[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example 1
[0023] like Figure 1 As shown;
[0024] A filter effect detection auxiliary device comprises a box body 1.
[0025] In this embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "conventional detection auxiliary devices are expensive, and the filter sizes that can be detected are limited. A single monitoring device can only monitor filters of one size, which has great limitations." In terms of actual use, this problem is obviously a real problem that exists and is difficult to solve. Therefore, in order to solve this technical problem, a partition component 2 is added on this basis.
[0026] like Figure 1-Figure 4 As shown;
[0027] In combination with the above content, in order to improve the flexibility of the device and facilitate monitoring of filters of different sizes, it also includes a partition component 2 arranged inside the box body 1;
[0028] The partition component 2 includes a limiting slide groove 21 opened on the two inner walls of the box body 1, a limiting slider 22 that slides back and forth is arranged inside the limiting slide groove 21, a partition plate 23 that moves back and forth inside the box body 1 is arranged between the two limiting sliders 22, and a cylinder 24 that drives the limiting slider 22 to slide back and forth is arranged inside the limiting slide groove 21 on the front side wall of the limiting slider 22.
[0029] In an optional embodiment, a sealing cover is sleeved on the limit slider 22, which is sealed with the limit slide groove 21, and sealing gaskets are fixed to the left and right side walls of the partition 23, which are sealed with the left and right side walls of the box body 1. The limit slider 22 matches the limit slide groove 21, and the limit slider 22 slides back and forth inside the limit slide groove 21.
[0030] In this embodiment: the limit slider 22 is driven by the cylinder 24 to slide back and forth inside the limit slide groove 21. Since the partition 23 is set between the two limit sliders 22, the partition 23 follows the limit slider 22 to move back and forth, thereby adjusting the size of the two partition areas inside the box body 1.
[0031] In an optional embodiment, a fan 11 is installed on the left side wall of the box body 1 , and an air outlet of the fan 11 extends into the interior of the box body 1 .
[0032] In an optional embodiment, the partition 23 divides the interior of the box body 1 into a filter placement area and a sealing area.
[0033] In an optional embodiment, the box body 1 at the top of the filter placement area is covered with a hollow cover plate 12, and the box body 1 at the top of the sealing area is covered with a cover plate 13. An air collecting hood 14 is installed in the hollow part of the hollow cover plate 12, and an air outlet detection port 15 is provided on the top of the air collecting hood 14.
[0034] In this implementation scheme: a cover plate, a hollow cover plate, and an air collecting hood form a group. The size of the bottom of the air collecting hood is the same as that of the hollow cover plate. The cover plate and the hollow cover plate are spliced and fit with the top of the box to ensure air tightness. By using multiple sets of cover plates and air collecting hoods, it can be used to detect filters of various sizes.
[0035] The working principle of the utility model is as follows: before use, according to the size of the filter to be tested, the movable partition is adjusted so that the length of the filter placement area matches the length of the filter, and then a cover is placed above the sealing area to make the sealing area an independent closed space. The filter placement area is covered with a hollow cover, and the filter to be tested is placed. The air collecting hood is covered, the fan is turned on, and the dust particle detector is used to detect the amount of dust particles near the fan. After a period of time, the amount of dust particles is detected at the air outlet of the air collecting hood to complete the detection of the filtering effect. 24 drives the limit slider 22 to slide back and forth inside the limit slide groove 21. Since the partition 23 is set between the two limit sliders 22, the partition 23 follows the limit slider 22 to move back and forth, thereby adjusting the size of the two separated areas inside the box body 1. A cover plate, a hollow cover plate, and an air collecting hood are a group. The size of the bottom of the air collecting hood is the same as that of the hollow cover plate. The cover plate and the hollow cover plate are spliced and fit with the top of the box to ensure air tightness. Through the coordinated use of multiple sets of cover plates and air collecting hoods, it can be suitable for the detection of filters of various sizes.
[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
