Title:
MAGNETRON AND MICROWAVE HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/065914
Kind Code:
A1
Abstract:
A magnetron and a microwave heating device. The magnetron comprises a tube core (21), a first tube shell (21a), a second tube shell (21b), an output ceramic (22), an antenna cap (23) and an antenna (24). The first tube shell (21a), the tube core (21), the second tube shell (21b), the output ceramic (22) and the antenna cap (23) are connected in sequence. The antenna (24) extends into the tube core (21), and sequentially passes through the second tube shell (21b) and the output ceramic (22) and extends into the antenna cap (23). The height H1 of the second tube shell (21b) relative to the tube core (21) is not greater than 14 mm, and the ratio of the height H1 of the tube core (21) to the height H2 of the output ceramic (22) is within the range of 0.4 to 2.3.
