The sealing member 2 seals the gap between the antenna 300 and the mounting hole 1, and the hole wall of the mounting hole 1 is embedded in the embedding groove 21 and is interference fit with the sealing member 2, which improves the sealing reliability of the sealing member 2, can effectively avoid safety hazards caused by excessive microwave leakage, and prevent steam or oil smoke from penetrating into the inner pot to affect the normal use of the user, and can also improve the efficiency of heating food by the microwave heating device.

[0043] In this embodiment, the cavity wall of the inner pot 100 provided with the mounting hole 1 is convexly provided toward the outer side of the inner pot 100 to form a first boss 3, the interior of the first boss 3 forms a first accommodating cavity, and the portion of the sealing member 2 located in the inner pot 100 is located in the first accommodating cavity. The sealing member 2 is not protruded from the inner side of the cavity wall of the inner pot 100, the sealing member 2 does not occupy the space inside the inner pot 100, and does not affect the installation of other components in the microwave heating device.

[0044] The wall of the mounting hole 1 is bent outwardly along the circumferential direction to form a flange 12, which is fitted with the outer wall of the first boss 3, and the flange 12 and the wall of the mounting hole 1 are both inserted into the embedding groove 21. The flange 12 improves the connection strength between the seal and the mounting hole 1, thereby improving the reliability of the installation of the seal 2.

[0045] The sealing member 2 is made of an elastic and deformable material, so as to be embedded in the mounting hole 1 and to achieve an interference fit with the antenna 300 , thereby achieving a good sealing effect.

[0046] In this embodiment, the cavity wall of the inner liner 100 is provided with a second boss 4 protruding outward, a second accommodating cavity is formed inside the second boss 4, and the first boss 3 is formed on the second boss 4, that is, the cavity wall of the inner liner 100 is provided with second bosses 4 and first bosses 3 of different sizes protruding outward in sequence, the first accommodating cavity is connected to the second accommodating cavity, and the antenna 300 is fixedly connected to the second boss 4. During installation, one end of the antenna 300 is provided with the second boss 4 and the mounting hole 1 in sequence, and the other end of the antenna 300 is limited by the cavity bottom of the second accommodating cavity and is located in the second accommodating cavity, which plays a role in positioning the antenna 300. It is also convenient to assemble the antenna 300 toward the top of the inner liner 100, reduce the extension size of the antenna 300 into the inner liner 100, and increase the effective volume of the inner liner 100.

[0047] In this embodiment, a shielding member 5 is sleeved on the outer side of the antenna 300, and the shielding member 5 is interference-fitted with the outer side wall of the antenna 300. The shielding member 5 can further shield the microwaves leaking through the mounting hole 1 and the antenna 300.

[0048] Optionally, the antenna 300 is connected to a flange 301 located inside the inner pot 100, the shielding member 5 is arranged between the flange 301 and the cavity wall of the inner pot 100, and the flange 301 is fixed to the inner pot 100 by a first fastener to position the shielding member 5. The flange 301 plays a role in fixing the shielding member 5, and the shielding member 5 can effectively prevent microwaves from leaking from the gap between the mounting hole 1 and the antenna 300, and can also isolate the corrosion of the sealing member 2 by oil smoke, steam, etc. when heating meat food, thereby enhancing the sealing reliability between the sealing member 2, the antenna 300 and the inner pot 100.

[0049] The first fastener passes through the flange plate 301, the shielding member 5 and the cavity wall of the inner liner 100 in sequence for connection, and the shielding member 5 is pressed against the inner side of the cavity wall of the inner liner 100, thereby improving the microwave shielding effect of the shielding member 5.

Under the action of the connecting force of the first connector 6 and the second connector 7, the flange 301 applies force to the shielding member 5, so that the shielding member 5 is pressed against the inner wall of the inner liner 100, thereby improving the sealing between the inner liner 100 and the antenna 300.

[0051] The first connecting member 6 may be a bolt, and the second connecting member 7 may be a nut. The connecting structure is simple and easy to install.

[0052] The portion of the sealing member 2 disposed in the inner liner 100 can be completely disposed in the first accommodation cavity, or the portion of the sealing member 2 disposed in the inner liner 100 is flush with the cavity opening of the first accommodation cavity, which can ensure that the shielding member 5 is disposed in close contact with the inner wall of the inner liner 100, thereby improving the sealing between the inner liner 100 and the antenna 300. In the case of providing the second boss 4, the shielding member 5 is disposed in close contact with the cavity bottom of the second accommodation cavity of the second boss 4.

[0053] The thickness of the shielding member 5 is set to 0.6 mm to 1.5 mm. Under the premise of ensuring the sealing performance, the thickness of the shielding member 5 is reduced to improve the compactness of the structure of the microwave heating device. Optionally, the thickness of the shielding member 5 is 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm or 1.5 mm, which is not specifically limited here.

[0055] Embodiment 2

The microwave heating device includes an inner pot 100, and a microwave solid-state source 200, a DC power supply 400, a power board 500, and a heat dissipation fan 600 are arranged outside the inner pot 100. The microwave solid-state source 200 is connected to an antenna 300 through a coaxial cable 700, and one end of the antenna 300 passes through the inner pot 100 and is placed inside the inner pot 100. The power board 500 and the DC power supply 400 are used to supply power to the microwave solid-state source 200, and the heat dissipation fan 600 is used to dissipate heat for the microwave solid-state source 200, the antenna 300, the power board 500, etc. The microwave solid-state source 200 emits microwaves of a certain wavelength, and the microwaves are fed into the inner pot 100 through the coaxial cable 700 and the antenna 300 to heat the food.

[0057] The inner pot 100 is a food heating area, and the antenna 300 is a microwave feeding component.

The provision of the second crimping member 9 supports the shielding member 5, thereby preventing a gap from appearing between the shielding member 5 and the antenna 300 under the pressure of the first crimping member 8, thereby affecting the shielding effect of the shielding member 5.

[0060] The second crimping member 9 includes a second crimping body 91 and a support plate 92.

The inner diameter of the support plate 92 is larger than the outer diameter of the portion of the sealing member 2 located outside the inner liner 100. The shielding member 5 abuts between the second crimping body 91 and the first crimping member 8. The second crimping body 91 is placed between the shielding member 5 and the sealing member 2. The inner diameter of the support plate 92 is larger than the outer diameter of the sealing member 2, so as to provide sufficient support force for the setting of the shielding member 5 and improve the shielding effect of the shielding member 5. The side wall of the second crimping body 91 is bent along the circumferential direction to provide a support plate 92. The support plate 92 abuts against the outer side of the cavity wall of the inner liner 100.

Under the action of the connecting force of the third connector 10 and the fourth connector 11, the first crimping member 8 applies force to the shielding member 5, so that the shielding member 5 is pressed against the second crimping member 9, thereby improving the sealing between the liner 100 and the antenna 300.

[0063] The third connecting member 10 may be a bolt, and the fourth connecting member 11 may be a nut. The connecting structure is simple and easy to install.
