When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0023] See also Figure 1 and Figure 2As shown, a microwave treatment device according to an embodiment of the utility model comprises a microwave treatment handle 200 and a microwave treatment head 100, and the microwave treatment head 100 is detachably connected to the microwave treatment handle 200. Since the microwave treatment head 100 is used as a disposable consumable during the microwave energy output treatment of the microwave treatment device, the microwave treatment head 100 is detachably connected to the microwave treatment handle 200, which facilitates the rapid replacement of the microwave treatment head 100.

[0024] The microwave treatment handle 200 includes a shell 2 and a waveguide antenna assembly 3. The shell 2 is provided with an installation cavity 20. The waveguide antenna assembly 3 is arranged in the installation cavity 20. An installation frame 21 is provided at one end of the installation cavity 20 close to the microwave treatment head 100.

By pressing the button 17, the first hook 16 and the second hook 27 are separated, thereby realizing the quick separation of the microwave therapy head 100 and the microwave therapy handle 200, thereby improving the speed of assembly and disassembly of the microwave therapy head 100 and the microwave therapy handle 200.

[0035] The mounting frame 21 includes a mounting plate 211 disposed on the inner wall of the housing 2, and the mounting opening 22 is disposed in the middle of the mounting plate 211. The receiving chamber 11 is provided with a receiving opening for receiving the energy transmitting end of the waveguide antenna assembly 3, and the receiving opening is opposite to the mounting opening 22.

[0036] The housing 2 includes a mounting portion 2-2 and a holding portion 2-1.

[0038] In addition, a foreign matter receiving portion 131 is provided in the negative pressure communication chamber 13, and the foreign matter receiving portion 131 is located below the negative pressure air inlet 14. The foreign matter receiving portion 131 can receive foreign matter such as blood, sweat, and other liquids or tissues that enter the negative pressure communication chamber 13 and are isolated by the hydrophobic breathable membrane in the negative pressure channel 13.
