HEATING ONE-WAY DISPENSER

WIPO Patent Application WO/2020/155682

A1

A heating one-way dispenser, comprising: a housing (1), two feed openings (2) provided on the upper surface of the housing and communicated with each other, a feed channel (3) connected between the feed openings, a travel guide sleeve (3) provided in the feed channel, a sealing ball seat (4) sleeved on the travel guide sleeve, a sealing steel ball (5) mounted on the sealing ball seat, a discharge channel (6) provided in an intermediate position of the sealing channel and penetrating through the sealing channel in a normal direction, and a plurality of discharge ports (7) provided around the housing and communicated with the discharge channel. By means of the fluid pressure, the dispenser can push the sealing steel ball with the pushing force of the fluid per se to open or close the discharge channel so as to realize dispensing of glue to the corresponding channel and a reverse cutoff function of the other channel; temperature heating control is carried out on the dispenser by means of a heating temperature control device, so that the fluidity of the flowing viscous fluid is improved, and the reaction speed of shutoff and dispensing of a check valve is improved; the problem that the existing apparatus is prone to gluing backflow in the use process is solved.
