[0026] like Figure 2 , Figure 3 and Figure 4 as well as Figure 5As shown, the wall surface of the sliding seat 11 is provided with a detachable cleaning assembly, and the cleaning assembly includes an outer shell 20, a collecting body 21 and a guiding body 30. The outer shell 20 is fixedly connected to the sliding seat 11, and the collecting body 21 is detachably connected to the outer shell 20. The outer shell 20 has a cavity, and a plurality of guiding bodies 30 are arranged on the top surface of the outer shell 20. The plurality of guiding bodies 30 form interval channels and guide the cleaning liquid into the collecting body 21 for filtration. The collecting body 21 forms a box structure with an opening at the top. The guiding body 30 is fixedly installed on the top surface of the collecting body 21. The top surface of the collecting body 21 is linearly distributed with a plurality of guiding bodies 30. The guiding body 30 is of equal length to the collecting body 21. The top of the guiding body 30 forms a free end, and the guiding body 30 extends obliquely in a direction away from the opening of the collecting body 21. In the present scheme, a collecting body 21 is provided and placed inside the outer shell 20. The cleaning liquid sprayed on the top surface of the sliding seat 11 flows into the collecting body 21. After being filtered by the collecting body 21, the debris and welding slag are stored in the cavity of the collecting body 21, thereby filtering the cleaning liquid, reducing the impurities in the cleaning liquid in the cavity of the base 10, and inhibiting clogging. A plurality of guide bodies 30 are provided, and an inclined extending fin structure is formed by the plurality of guide bodies 30. When the cleaning liquid sprayed from the nozzle impacts the sliding seat 11, the liquid impacts each guide body 30. The guide body 30 is used to guide the liquid into the cavity of the collecting body 21, thereby inhibiting the splashing of the inclined liquid, enabling better filtering, and alleviating the impurities in the splashing liquid from directly falling back into the cavity of the base 10 to pollute the cleaning liquid.

[0027] like Figure 5 As shown, the horizontal cross-section of the guide body 30 includes a rectangle but is not limited to a rectangle, and the length of each guide body 30 decreases evenly toward the direction close to the sliding seat 11. In the present embodiment, the guide body 30 takes a rectangular plate as an example, and collects the cleaning liquid by means of the inclined extended rectangular plate. The guide body 30 with decreasing size is the shortest near the sliding seat 11, which can ensure that the cleaning liquid splashed near the sliding seat 11 can be quickly introduced into the collecting body 21, and the design of the highest guide body 30 away from the sliding seat 11 can further suppress the splashed liquid from falling into the cavity of the base 10, thereby achieving a better collection effect.

[0028] A number of holes for drainage are evenly arranged on the bottom surface of the collecting body 21, and filter material is laid on the bottom surface of the collecting body 21. The holes and filter material are not shown in the figure. The filter material in the collecting body 21 can be a sponge. In conjunction with the holes at the bottom of the collecting body 21, the liquid flows back from the holes to the cavity of the base 10, and impurities are stored in the collecting body 21. The collecting body 21 can be taken out for cleaning and maintenance, which has the characteristics of convenient maintenance, simple and efficient operation.

The collecting body 21 is arranged in the belly of the outer shell 20. The opposite side walls of the outer shell 20 are fixedly connected with baffles 22. The top of the collecting body 21 forms a retaining edge, and the bottom surface of the retaining edge of the collecting body 21 abuts against the baffle 22. By setting the baffle 22, the baffle 22 is used to form a support on the bottom surface of the collecting body 21, so that the collecting body 21 can be prevented from falling off in the cavity of the outer shell 20, and at the same time, the convenience of removing the collecting body 21 is guaranteed. It should be noted that this scheme is suitable for the circuit board of the instrument, and the overall size is relatively small. It is not used for cleaning large circuit boards, so there are no excessive restrictions on the overall size.

[0030] The working principle of the utility model is as follows: the collecting body 21 is placed in the belly of the outer shell 20, the cleaning liquid sprayed on the top surface of the sliding seat 11 flows into the collecting body 21, the liquid impacts each guide body 30, and the guide body 30 is used to guide the liquid into the cavity of the collecting body 21, and the splashing of the tilting liquid is suppressed. After filtering by the collecting body 21, the debris and welding slag are stored in the cavity of the collecting body 21, so as to achieve the filtration of the cleaning liquid and reduce the impurities in the cleaning liquid in the cavity of the base 10;

[0031] The baffle 22 is used to form a support on the bottom surface of the collector 21, so that the collector 21 can be prevented from falling off in the cavity of the outer shell 20, so that the collector 21 can be installed and removed when cleaning impurities and welding slag.
