Field of the Disclosure

[0002] The present disclosure relates to a SPA swimming pool, and in particular to a SPA air pump with an inflating function and a SPA swimming pool.

Background of the Disclosure

[0003] Swimming pools including a SPA massage function are gradually becoming popular among consumers. In addition to normal swimming pool functions, SPA massage swimming pools can input high-pressure air into the pool through the SPA air pump, thereby achieving a massaging effect on the human body.

[0004] The function of the SPA air pump in existing technology is relatively simple. The SPA air pump intakes external air and flushes it into the water creating bubbles that massage the human body.

[0005] When the swimming pool is an inflatable product, the user needs to prepare an air pump to inflate the inflatable product. This air pump is in addition to the SPA air pump, which is very inconvenient and requires too many items to prepare.

[0006] An improved SPA air pump that can provide massaging bubbles and inflate the swimming pool is desired.

[0050] As shown in FIGS. 1 to 6, the present disclosure provides a SPA air pump with an inflating function. The SPA air pump with an inflating function may comprise a housing 1 and an air nozzle 2. The housing may be a monolithically formed structure or formed from multiple parts. The housing 1 comprises an air inlet 11, a first air outlet 12 connected to a water cavity of an inflatable product, such as a swimming pool, and a second air outlet 13 for inflating an air cavity of the inflatable product. In embodiments, second air outlet 13 may connect to the air cavity of the inflatable product through a conduit. The conduit may be flexible or rigid. FIG. 7 depicts an exemplary inflatable product 100. Inflatable product 100 is an inflatable swimming pool that includes a bottom wall 104, an internal side wall 106, and an external side wall 108. Internal side wall 106 and external side wall cooperate to define an air cavity 110. In embodiments, internal side wall 106 and external side wall 108 cooperate with bottom wall 104 and a top wall 109 to define air cavity 110. Internal side wall 106 and bottom wall 104 cooperate to define a water cavity 112. An internal piping structure may be provided in the air cavity 110. The internal piping structure may include nozzles that terminate in the water cavity, and the first air outlet 12 may be in fluid communication with the internal piping structure to provide massage bubbles to the water cavity through the internal piping structure and nozzles.

[0051 ] In embodiments, air nozzle 2 may carry a locking member 20 which cooperates with an inner wall of the second air outlet 13 to secure the air nozzle 2 in place within the second air outlet 13. In the illustrated embodiment, the inner wall of the second air outlet 13 is a blocker 15. Exemplary blockers include tabs and other suitable shapes to limit movement. In the illustrated embodiment, locking member 20 includes a hook 22 formed on an extension portion 21 of the air nozzle 2. The locking member 20 is rotatable from a first unlocked position relative to the second air outlet to a second locked position relative to the second air outlet. In the unlocked position, the air nozzle 2 is removeable from the second air outlet 13. In the locked position, the air nozzle 2 is secured to the air outlet 13. Other arrangements of exemplary lock members 20 and blockers 15 may be used to secure air nozzle 2 to second air outlet 13.

[0052] In embodiments, the blocker 15 may extend from a first side of the second air outlet 13 to a second side of the second air outlet 13. For example, a portion of the second air outlet 13 may include a blocker 15 that extends substantially vertically within a portion of the second air outlet 13 to create two openings through a portion of the second air outlet 13. In embodiments, blocker 15 may extend horizontally within a portion of the second air outlet or at an angle between horizontal and vertical.

[0053] The housing 1 is equipped with an air passage 14. The first air outlet 12 is connected to the air passage 14, and the connection between the second air outlet 13 and the air passage 14 is provided with a movable sealing valve core 3. The sealing valve core 3 is connected to an elastic reset member 4 to bias the sealing valve core 3 to a first position in which the second air outlet 13 and the air passage 14 are sealed. As depicted in FIGS. 1, 2, 5, and 6, sealing valve core 3 may be formed with a channel 36. Channel 36 may receive stop 17, which serves to limit the translational movement of sealing valve core 3.

[0054] The air nozzle 2 is used to connect the sealing valve core 3 and the product to be inflated or deflated. The air nozzle 2 pushes the sealing valve core 3 to a second position in which the second air outlet 13 and the air passage 14 are connected, thus fluidly connecting the air inlet 11, the second air outlet 13, and the air cavity of the inflatable product. As indicated in FIG. 3, translational movement in a direction indicated by arrow A pushes the sealing valve core 3 to the second position. As the air nozzle 2 pushes the sealing valve core 3 to the second position against the biasing force of elastic reset member 4, the elastic reset member 4 accumulates an elastic reset force.

[0055] As stated, the SPA air pump with an inflating function is equipped with a second air outlet 13. The second air outlet 13 may connect to the air cavity 110 of the inflatable product through the air nozzle 2. This allows for inflation of the inflatable product without the need for an additional air pump, which is more convenient.

[0056] As discussed above and explained further below, when air nozzle 2 is inserted into second air outlet 13, the sealing valve core 3 is pushed to open to the second position, thereby connecting the second air outlet 13 with the air inlet 11 through air passage 14. After removing the air nozzle 2, the sealing valve core 3 will reset under the elastic resetting force accumulated in elastic reset member 4 and cut off the fluid connection between the second air outlet 13 and the air inlet 11 again, thus avoiding air leakage. In addition, when the second air outlet 13 is connected to the air inlet 11, the first air outlet 12 and the air inlet 11 remain connected. Thus, when using the SPA air pump to inflate, the SPA massage function can still be used normally.

[0057] To achieve the movement of the sealing valve core 3 to the second position by the air nozzle 2, the side of the sealing valve core 3 facing the air nozzle 2 has an abutting plate 31 extending towards the direction of the air nozzle 2. The abutting plate 31 is used to form a connection with the air nozzle 2. There may be two abutting plates 31, and an accommodating space 32 is formed between the two abutting plates 31 for the insertion of the air nozzle 2. The inner wall of the abutting plate 31 extends radially inward to form a shoulder 37. After being inserted into the accommodation space 32, the air nozzle 2 contacts the shoulder 37, thereby pushing the sealing valve core 3 to move. [0058] The air nozzle 2 has a locking member 20 which includes an extension portion 21 for inserting into the accommodation space 32. There may be two extension portions 21 corresponding to the two abutting plates 31. The extension portion 21 is provided with a hook 22. When the extension portion 21 of the air nozzle 2 is inserted into the accommodation space 32, the extension portion 21 of the air nozzle 2 contacts the shoulder 37 thereby pushing the abutting plate 31 inward to the second position, placing second air outlet 13 and air inlet 11 in communication via air passage 14.

[0059] When the air nozzle 2 is inserted into the second air outlet 13, the hook 22 of the air nozzle 2 extends beyond the blocker 15 formed in the second air outlet 13. The air nozzle

2 moves around its own axis, axis B as depicted in FIG. 3, between a first position, which may be an unlocked position, and a second position, which may be a locked position. When the air nozzle 2 is in the first position, the hook 22 is not positioned behind the blocker 15, and the air nozzle 2 can be removed from the second air outlet 13, and the sealing valve core

3 can close under the elastic restoring force of the elastic reset member 4. When the air nozzle 2 is in the second position, the hook 22 is positioned behind the blocker 15, locking the air nozzle 2 in place, and fixing the sealing valve core 3 in an open position against the biasing force of the elastic reset member 4. Thus, the air nozzle 2 relies on two degrees of freedom to lock the air nozzle 2 in place: a translational degree of freedom as indicated by arrow A in FIG. 3, and a rotational degree of freedom about axis B in FIG. 3.

[0060] To connect the SPA air pump with an inflating function to the air cavity of the inflatable product, the air nozzle 2 is formed with a threaded interface 23.

[0061] To seal the second air outlet 13 and air passage 14 when the sealing valve core 3 is in the first position, the sealing valve core 3 protrudes radially to form an abutting surface 33 having a protruding edge 34 on the side of the butting plate 31 away from the air nozzle 2. A sealing gasket 35 is arranged on the side of the protruding edge 34. When the sealing valve core 3 is in the first position, the sealing gasket 35 seals the side wall of the connection between the air passage 14 and the second air outlet 13. The abutting surface 33 distributes the force generated by the spring across the sealing gasket 35 to effect a seal of the second air outlet 13.

[0062] The elastic reset member 4 may be a spring. Alternatively, the elastic reset member can be replaced with other parts that can generate elastic reset force. [0063] The present disclosure further provides a SPA swimming pool, which comprises a swimming pool and an air pump arranged on the swimming pool, the air pump being the SPA air pump with an inflating function as described above.
