[0029] Figures 2 to 6 The microwave device cavity cleaning device provided by an embodiment of the present invention is collectively shown, which is used to clean the inner cavity of microwave devices such as filters, phase shifters, combiners, couplers, and duplexers. The device can complete the cleaning operation without removing the cover. Compared with the traditional cleaning method, it has high cleaning efficiency and good cleaning effect, and can effectively avoid secondary contamination caused by retuning after removing the cover for cleaning.

[0030] like Figure 1As shown, in order to conveniently explain the specific structure and use of the microwave device inner cavity cleaning device, a microwave device 1 suitable for the microwave device inner cavity cleaning device is shown in the figure, and the microwave device 1 includes a shell 11 and a port 12 connected to the shell 11, and an inner cavity 100 (in the inner cavity 100) opened in the shell 11 Figure 5 As shown in the figure, the shell 11 is preset with an air inlet hole 111 and an air outlet hole 112 both connected to the inner cavity 100, and the inner cavity 100 has at least one through air duct between the air inlet hole 111 and the air outlet hole 112.

[0031] like Figure 2 As shown, the microwave device inner cavity cleaning device 2 includes a frame 21, a positioning fixture 22, a blowing device 23 and a dust suction device 24 all arranged on the frame 21, the positioning fixture 22 is used to install and fix the microwave device 1, the blowing device 23 is used to blow clean compressed air into the inner cavity 100 through the air inlet 111 to blow the pollutants in the inner cavity 100 to the vicinity of the air outlet 112, and the dust suction device 24 is used to suck out the pollutants in the inner cavity 100 together with the gas through the air outlet 112.

[0032] Please combine Figure 3 Specifically, the blowing device 23 includes an air source 231 and an air blowing nozzle 232 connected to the air source 231, the air blowing nozzle 232 is arranged on the positioning fixture 22 and is used to dock with the air inlet 111, the dust suction device 24 includes a dust collector 241 and an air suction nozzle 242 connected to the dust collector 241, the air suction nozzle 242 is arranged on the positioning fixture 22 and is used to dock with the air outlet 112, and while blowing gas into the inner cavity 100 through the air blowing nozzle 232, the pollutants in the inner cavity 100 can be sucked out together with the gas through the air suction nozzle 241. The process of cleaning the inner cavity 100 does not require disassembly of the cover plate of the microwave device 1, and the cleaning efficiency is high and the cleaning effect is good.

[0033] Furthermore, the positioning fixture 22 includes a slot 221 and a clamping claw 222, the slot 221 is adapted to the shell 11 and is used to be embedded in the shell 11, and the clamping claw 222 is adapted to the port 12 and is used to clamp the port 12, while ensuring installation stability and positioning accuracy, the slot 221 and the clamping claw 222 can be used to quickly fix and separate the microwave device 1, so as to facilitate the batch cleaning process of multiple microwave devices 1.

[0034] like Figure 4 As shown, the blowing nozzle 232 includes a blowing hole 2321 that can penetrate into the inner cavity 100 along the air inlet hole 111 , and the blowing nozzle 232 is bent or tilted so that the blowing hole 2321 is tilted toward the suction nozzle 241 .

[0035] Please combine Figure 5 For the air nozzle structure perpendicular to the bottom surface of the shell 11, the air blown out will directly rush to the inner wall of the shell 11, causing most of the energy of the air flow to be absorbed by the shell 11, making it difficult for the air to diffuse and flow at high speed in the inner cavity 100, resulting in poor cleaning effect. The air blowing nozzle 232 is bent or tilted to tilt the air blowing hole 2321 toward the air suction nozzle 241, so that the air blown out of the air blowing hole 2321 can flow more smoothly toward the air suction nozzle 241 at high speed, thereby better driving the pollutants to the vicinity of the air suction nozzle 241, greatly improving the cleaning effect.

[0036] Preferably, the blowing device 23 also includes a holder 233, the blowing nozzle 232 is arranged on the holder 233, and the positioning fixture 22 is provided with a slide groove 223 adapted to the holder 233, and the holder 233 is detachably connected to the positioning fixture 22 through the slide groove 223, thereby facilitating the disassembly and replacement of the blowing nozzle 232 to adapt to microwave devices 1 of different specifications, thereby improving the applicability of the blowing device 23.

[0037] Preferably, the slide grooves 223 are provided in plurality, and the slide grooves 223 extend along the surface of the positioning fixture 22 to form at least one limiting space for the holder 233 to adjust the position, and the holder 233 is embedded in the slide grooves 223 and can slide along the slide grooves 223. Since a large number of protruding screws and screws are arranged on the surface of the housing 11, the opening position of the air inlet 111 needs to be avoided, resulting in the position of the air inlet 111 being misaligned to varying degrees. At this time, the blowing nozzle 232 can be moved and adjusted through the holder 233, and can adapt to the air inlet 111 opened at different positions, further improving the applicability of the blowing device 23.

[0038] Preferably, the blowing nozzles 232 are provided in plurality, and the plurality of blowing nozzles 232 are connected to the gas source 231 and arranged at intervals. The gas source 231 can switchably control one or more blowing nozzles 232 to start and blow out gas.

[0039] Correspondingly, the shell 11 of the microwave device 1 is provided with a plurality of air inlet holes 111, and a plurality of air blowing nozzles 232 are arranged in correspondence with each other in the plurality of air inlet holes 111. A specific cleaning method can be set by the air source 231 and the related control circuit to ensure the cleaning effect. For example, when the plurality of air blowing nozzles 232 are respectively the first air blowing nozzle, the second air blowing nozzle and the third air blowing nozzle, the first air blowing nozzle can be started to start blowing to clean a part of the area, and then the second air blowing nozzle can be started to start blowing to clean another part of the area, and then the third air blowing nozzle can be started to blow to clean the last part of the area, and finally the first, second and third air blowing nozzles can be started at the same time to start blowing to clean the whole area, and the vacuum cleaner 241 can be kept in an open state throughout the whole process. In actual use, cleaning can be performed according to the cleaning requirements of each passage inside the microwave device 1, and the cleaning of different positions of the inner cavity 100 can be completed in a planned manner through the plurality of air blowing nozzles 232, so that the cleaning effect is better.

[0043] Specifically, the shaking device 25 includes a power component 251, a base 252 and a bracket 253. The bracket 253 is arranged on the base 252 and can rotate relative to the base 252. The power component 251 includes a rotary cylinder or a motor connected to the bracket 253. The power component 251 can drive the bracket 253 to reciprocate along the base 252.

[0044] Preferably, the base 252 and the power assembly 251 are arranged on both sides of the bracket 253, one end of the bracket 253 is connected to the base 252, and the other end is connected to the power assembly 251. That is, the base 252 and the power assembly 251 are not directly connected, so that the distance between the two is adjustable, and then different microwave devices 1 can be conveniently fixed by replacing brackets of different lengths to adapt to positioning fixtures of different specifications, thereby further improving the applicability of the microwave device inner cavity cleaning device 2.

[0045] Preferably, the shaking device 25 also includes a bearing (not shown in the figure, the same below) embedded in the base 252, and the bracket 253 is connected to the bearing.
