[0038] The structure of the remaining parts is the same as the structure and connection relationship described in Example 1 or Example 2, and will not be repeated here to avoid cumbersome writing.

[0039] On the basis of the above embodiments, the present application continues to combine the accompanying drawings to further describe the technical features involved and the working process of the present application, so as to help technical personnel in this field to fully understand the technical solution of the present application and be able to reproduce it.

[0040] In the present application, the box body 1 is used to place the nest frame 27, which is used as the basis for bees to build honeycombs. A nest frame stopper 28 needs to be provided at the connection position between the nest frame 27 and the box body 1. The nest frame stopper 28 should have a certain thickness and can be processed with a placement groove corresponding to the nest frame 27. The placement grooves are distributed in the length direction of the nest frame stopper 28. The presence of the placement grooves allows sufficient air flow gaps and bee activity gaps between adjacent nest frames 27.

[0041] In the present application, a plurality of side wall mite removal holes 26 distributed in a matrix are processed on the inner wall of the box body 1 which is arranged vertically to the nest frame 27. The side wall mite removal holes 26 on both sides of the nest frame 27 are respectively located at the upper and lower parts of the inner wall of the box body 1. This arrangement can facilitate the air carrying the mite removal agent to flow into the box body 1 from the upper side wall mite removal holes 26 in the first cycle and flow out from the lower side wall mite removal holes 26; in the second cycle, it flows in from the lower side wall mite removal holes 26 and flows out from the upper side wall mite removal holes 26.

[0042] In the present application, the side wall mite removal holes 26 are connected to corresponding pipelines respectively. Such pipelines refer to the side wall mite removal holes 26 in rows or the side wall mite removal holes 26 in columns, which are connected to the corresponding in-box air collecting boxes 18 through pipelines. The in-box air collecting boxes 18 are respectively located in the upper chamber and the lower chamber at the corresponding positions. The upper chamber and the lower chamber are formed in the side wall chamber 32 by the cavity partition 25. The side wall chamber 32 is formed by the outer box body 23 and the inner box body 24. The outer box body 23 and the inner box body 24 are connected to form a whole box body 1 through the cavity partition 25.

[0043] The mite removal agent can be placed in the air collecting box 18 in the box, and is released under the action of the air input by the rear end branch pipe 16 and flows out from the corresponding mite removal holes 26 on the side wall through the pipeline.

[0044] The rear branch pipe 16 is a branch pipeline of the distribution tube outlet pipe 14. The top of the distribution tube outlet pipe 14 has multiple joints, each of which is connected to the distribution tube 5 at the corresponding position. The distribution tube 5 is fixed to the side wall of the cover body 2 through the distribution tube seat body 4. The inside of the distribution tube 5 is provided with a push rod piston 13 that moves relative to it. When the push rod piston 13 reciprocates inside the distribution tube 5, it can send the gas sent into the distribution tube inlet pipe 6 into the distribution tube outlet pipe 14, and can also send the gas in the distribution tube outlet pipe 14 into the distribution tube inlet pipe 6, so as to realize the first cycle and the second cycle.

[0045] Based on the description in the above paragraph, the connection position between the distribution tube air inlet pipe 6 and the distribution tube 5, and the connection position between the distribution tube air outlet pipe 14 and the distribution tube 5 need to be provided with a one-way valve with opposite opening states, so as to ensure the smooth progress of the first cycle and the second cycle process. In the present application, the distribution tube air inlet pipe 6 is connected to the medicine placement box 7, and the medicine placement box 7 also includes a placement box air inlet pipe 8, and the placement box air inlet pipe 8 is connected to the internal chamber of the cover body 2 through the top filter tube 9. The above structure can ensure the fluidity of the air in the cover body 2 and solve the problem of the gas source in the medicine placement box 7, and when the number of cycles increases, the supply of the mite removal agent can be reduced.

[0046] In the present application, the cover body 2 is also integrally provided with an outer box body 23 at the top, the bottom end of the outer box body 23 is connected to the internal chamber of the cover body 2, and a box exhaust plate 11 with a plurality of through holes is integrally provided at the top opening position of the outer box body 23. The inside of the outer box body 23 is connected to the ventilation filter cartridge 30 through a frame, the bottom end of the ventilation filter cartridge 30 is blocked, and the top end is blocked by the box exhaust plate 11, the ventilation filter cartridge 30 includes a filter outer shell and a filter inner shell, and the filter inner shell and the filter outer shell are respectively processed with a plurality of filter holes on the circumferential side walls, and a gap sufficient for the filter core to fill is left between the filter inner shell and the filter outer shell. The gas in the cover body 2 enters the ventilation filter cartridge 30 through the filter outer shell, the filter core, and the filter inner shell, and is discharged through the box exhaust plate 11 under the action of the ventilation fan 31 inside the ventilation filter cartridge 30. The function of this structure is to promote the gas at the box inlet 19 to flow into the interior of the cover body 2, and to send the gas inside the cover body 2 out through the ventilation filter cartridge 30 and the ventilation fan body 31, so as to realize the flow of internal airflow, improve fluidity, and facilitate the diffusion of the mite removal agent sent through the side wall mite removal hole 26 in the box body 1, thereby improving the degree of diffusion.

[0047] In the present application, the top filter cartridge 9 also needs to be filled with a filter core, and the function of the filter core is to filter the air inside the cover body 2 to avoid affecting the medicine in the medicine placement box 7 and the medicine in the box air collection box 18, thereby improving the use of the medicine. The top filter cartridge 9 is distributed at the top plate 10 of the box body in the circumferential direction of the box body exhaust plate 11, and corresponds to the placement box air inlet pipe 8 at the location.

[0048] In the present application, a shock absorbing structure, such as a shock absorbing gasket, may be provided at the connection position between the cover connecting portion 3 and the top end surface of the box body 1 to prevent the working device on the top of the cover body 2 from affecting the bee colony in the box body 1. Figures 1 to 5 In the structure shown in , grooves sufficient for placing shock-absorbing gaskets are reserved on the top end surface of the box body 1 and the bottom end surface of the cover body connecting part 3. In addition to the above-mentioned positions, shock-absorbing gaskets also need to be distributed on the connecting end surfaces of the box body 1 and the cover body connecting part 3.

[0049] In the present application, in addition to forming an entrance at the bottom of one side of the box 1, the box entrance 19 also needs to extend a certain distance away from the box 1 to ensure that there are sufficient inlet exhaust holes 20 distributed on the top inner wall and bottom surface of the box entrance 19, so that the mite removal agent delivered by the front branch pipe 15 can be sprayed into the position of the box entrance 19 through the inlet exhaust holes 20, thereby realizing the mite removal operation for the bees entering and exiting through the box entrance 19.

[0050] The front end branch pipe 15 can be connected to the front end branch pipe 15 through the corresponding front end air collecting boxes 17 on both sides, and the front end branch pipe 15 is connected to the distribution tube outlet pipe 14, which is also under the control of the distribution tube 5. During the relative movement of the push rod piston 13 and the distribution tube 5, the alternation of the first cycle and the second cycle can be realized.

[0051] The movement processes of the distribution cylinders 5 connected on both sides of the cover body 2 are opposite, that is, when the distribution cylinder 5 and the push rod piston 13 on one side of the cover body 2 are pushed in the direction of the distribution cylinder outlet pipe 14, the distribution cylinder 5 and the push rod piston 13 on the other side move in the direction away from the distribution cylinder outlet pipe 14.

[0052] At the entrance of the box entrance 19, a baffle may be hingedly provided, the top of the baffle being hinged to the top of the box entrance 19, and a gap sufficient for movement is left between the bottom of the baffle and the bottom end surface of the box entrance 19. When the bee moves toward the box entrance 19, the baffle can be rotated toward the inside of the box entrance 19 under the action of the top hinge, and when the bee is separated from the baffle, the baffle returns to a natural drooping state under the action of natural gravity.

[0053] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
