[0021] like Figures 1 to 3 As shown, an embodiment of the utility model discloses a microwave treatment handle with a self-heating function, including a shell 1 and a waveguide antenna assembly 2. The shell 1 is provided with a mounting cavity 10, and the waveguide antenna assembly 2 is arranged in the mounting cavity 10.

[0022] The waveguide antenna assembly 2 includes a heat dissipation device 3, an antenna bracket 21, and a plurality of waveguide antennas 22 arranged side by side. The antenna bracket 21 is provided with a storage groove 211, and the waveguide antenna 22 is arranged in the storage groove 211. The antenna bracket 22 is also provided with a cooling chamber 212, which is a sealed cavity. The cooling chamber 212 surrounds the four sides and the bottom of the storage groove 211, and the cooling chamber 212 is filled with a coolant. Since the cooling chamber 212 surrounds the four sides and the bottom of the storage groove 211, the coolant can be wrapped around the waveguide antenna 22, so as to facilitate the cooling of the waveguide antenna 22.

[0023] The heat dissipation device 3 includes a heat conducting plate 31, a heat pipe 32 and a cooling module. The heat conducting plate 31 is fitted on the side wall of the antenna bracket 21. The heat conducting plate 31 can form a part of the side wall of the antenna bracket 21, so that the heat conducting plate 31 is directly in contact with the coolant to reduce the heat conduction barrier and improve the heat conduction efficiency. One end of the heat pipe 32 is connected to the heat conducting plate 31, and the other end is connected to the cooling module. The cooling module and the heat conducting plate 31 are respectively located on different peripheral sides of the antenna bracket 22, which is conducive to improving the structural layout of the waveguide antenna assembly 2 and improving the heat dissipation efficiency.

[0024] The heat generated by the waveguide antenna 22 when working will first be absorbed by the coolant, and then the heat absorbed by the coolant will be transferred to the heat pipe 32 through the heat conduction plate 31. The heat pipe 32 has excellent thermal conductivity and thermal conduction efficiency, and can quickly transfer the heat on the heat conduction plate 31 to the cooling module. The cooling module quickly diffuses the heat transferred by the heat pipe 32 to the outside world, thereby cooling the waveguide antenna 22.

[0025] Preferably, the cooling module includes a heat sink 33, a fan 34 and a radiator 35, wherein the fan 34 and the radiator 35 are arranged on the heat sink 33. The radiator 35 is provided with a plurality of groups of heat sinks that are spaced and arranged side by side, which can increase the contact area between the heat sink and the outside and improve the heat conduction efficiency. The fan 34 is provided with a first air inlet 341 and a first air outlet 342, and the radiator 35 is arranged immediately in front of the first air outlet 342. A second air inlet 13 is provided on the side wall of the housing 1 at a position directly opposite to the first air inlet 341, and a second air outlet 14 is provided on the side wall of the housing 1 at a position directly opposite to the radiator 35.

[0026] The air inlet direction of the first air inlet 341 is perpendicular to the air outlet direction of the first air outlet 342. The fan 32 is a centrifugal fan. Air can be sucked in through the second air inlet 13 on the side of the housing 1, pass through the first air inlet 341 to reach the blades of the fan 32, and be thrown out from the first air outlet 342 under the rotation of the blades. That is, the air is sucked in from the axial direction of the centrifugal fan, thrown out from the radial direction of the centrifugal fan, and forms hot air after thermal convection with the heat sink 33 and the radiator 35. The hot air is then thrown out from the second air outlet 14 on the top of the housing 1, ensuring that the hot air coming out of the second air outlet 14 is as far away from the tissues around the treatment area as possible, so as to avoid the possibility that the hot air from the second air outlet 14 contacts the tissues around the treatment area during the operation of the handle.

[0027] A locking block 36 is provided at the position where the heat pipe 32 is connected to the heat conducting plate 31 . The side wall of the locking block 36 is provided with a locking groove matching the outer contour of the heat pipe 32 . The heat pipe 32 is correspondingly embedded in the locking groove. The locking block 36 is fastened to the heat conducting plate 31 to fix the heat pipe 32 .

[0028] In addition, two groups of heat pipes 32 and heat conducting plates 31 are provided, respectively located on two opposite sides of the antenna bracket 21, and the cooling module is located on the side between the two opposite sides of the antenna bracket 21. The structural layout of the waveguide antenna assembly 2 can be further improved, while improving the heat dissipation efficiency.

[0029] The bottom end of the storage groove 211 is connected to the cooling chamber 212, the energy emitting end of the waveguide antenna 22 is immersed in the cooling liquid, and a ceramic plate 23 is also provided at the bottom end of the cooling chamber, and the ceramic plate 23 is attached to the end surface of the energy emitting end of the waveguide antenna 22. The ceramic plate 23 is conducive to the penetration of microwaves and improves the treatment effect.

[0030] The housing 1 includes a bottom shell 11 and an upper cover 12. The installation cavity 10 is arranged in the bottom shell 11. The waveguide antenna assembly 2 and the heat dissipation device 3 are both arranged in the bottom shell 11. An opening is arranged at the top of the bottom shell 11. The upper cover 12 is detachably arranged on the opening to facilitate the assembly, disassembly and maintenance of the waveguide antenna assembly 2 and other components inside the housing 1.

The structural design requirements of the microwave treatment head are greatly simplified, and the structural complexity and design and manufacturing costs of the microwave treatment head are reduced.

[0032] The above is only an embodiment of the present invention and is not intended to limit the present invention.
