Description

Technical Field

[0001] The utility model relates to the technical field of air sampling devices, in particular to a disassembly tool for the air inlet filter of an air sampler. Background Technique

[0002] An air sampler is an instrument for collecting air pollutants or polluted air. There is a filter in the air sampler, whose function is to timely discharge the dust accumulated at the bottom of the air filter, preventing the dust in the air filter housing from accumulating more and more, so as to avoid prematurely clogging the air filter element. This design helps to protect the performance of the air filter, ensure the normal operation of the sampler, and extend its service life. In this way, the filter ensures that the sampler can continuously and effectively collect and analyze air samples, which is of great significance for environmental monitoring, scientific research, and air quality control in industrial production.

[0003] The filter is threadedly connected to the air inlet on the air sampler. After the filter on the air sampler has been used for a long time, it needs to be disassembled for filter replacement or internal filter membrane cleaning, as well as internal maintenance of the air sampler (personal air sampling pump).

[0004] There is an air inlet on the filter, and there are two cards on both sides of the air inlet. Since the filter is threadedly connected to the air sampler, when disassembling, the filter is rotated and disassembled from the air sampler by manually turning the cards. Since the cards are relatively small, when turning the filter, it is laborious and difficult to rotate, and it will cause great pain to the human hand. In the prior art, in addition to turning the cards to rotate and disassemble the filter, the filter can also be rotated and disassembled by clamping the air inlet of the filter with tweezers or pliers. However, this method is likely to damage the air inlet, resulting in the filter being unusable. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above problems, and a disassembly tool for the air inlet filter of an air sampler is designed to solve the problem that the filter on the air sampling device is small in size and inconvenient to disassemble.

[0006] To achieve the above purpose, the technical solution of the utility model is that a disassembly tool for the air inlet filter of an air sampler is used for quickly disassembling the air inlet filter of an air sampler. There are two cards on the filter to facilitate turning the filter to rotate. The disassembly tool includes a tool body. The bottom of the tool body has a cavity for accommodating the filter and at least two card slots for engaging with the cards on the filter. The upper part of the tool body has a screwing structure for facilitating turning the tool body to rotate.

[0007] A handle is provided on the upper part of the tool body for facilitating the rotation of the tool body, and the handle is integrally formed with the tool body.

[0008] Preferably, the outer contour of the upper portion of the tool body is a polygon.

[0009] Preferably, the top of the tool body has an interpenetrating hole with a polygonal cross-sectional shape.

[0010] Preferably, the insertion hole is provided with a rotating rod which is adapted to the shape of the insertion hole.

[0011] Preferably, a through hole is provided in the middle of the rotating rod, which passes through the rotating rod from top to bottom.

[0012] Preferably, the tool body has an air outlet hole connected to the mold cavity, and the air outlet hole is connected vertically.

[0013] Preferably, the top of the tool body protrudes outward to form a flange portion for facilitating manual pulling of the tool body.

[0014] Compared with the prior art, the beneficial effects are:

[0015] The disassembly tool of the utility model is used to disassemble the air inlet filter of the atmospheric sampler (individual air sampling pump), which is convenient for cleaning the filter membrane and replacing the filter. It is a practical small tool for maintenance. According to the appearance characteristics of the filter, a cavity is opened at the bottom of the tool body, and the tool can be directly put on the filter. The card on the filter will be connected with the card slot at the bottom of the tool body. There is a disassembly structure on the upper part of the tool body that is convenient for twisting the tool body by rotation. In this way, the tool can be twisted by hand to loosen the filter and easily disassembled, so as to replace the filter or clean the internal filter membrane, and perform internal maintenance operations on the atmospheric sampler (individual air sampling pump). Compared with the existing technology, the disassembly method of the filter is improved, which is more convenient, faster, and not easy to damage the filter. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] Embodiment 1

[0027] As Figure 1 , Figure 2 shown, a preferred embodiment of the present invention provides a disassembly tool for the filter tip at the air inlet of an air sampler. The filter tip 4 is threadedly connected to the air inlet on the air sampler 3. This disassembly tool can be sleeved on the filter tip 4 and is snap-connected to the card 401 on the filter tip 4. By rotating the disassembly tool, the filter tip 4 can be quickly disassembled.

[0028] Referring to Figures 3 - 5 , the disassembly tool mainly includes a tool body 1. At the bottom of the tool body 1, there is a cavity 101, and the shape of the cavity 101 is consistent with the shape of the filter tip 4. At the bottom of the tool body 1, at least two clamping grooves 102 (the number of the clamping grooves 102 is an integer multiple of the number of the cards 401) are provided in the circumferential direction of the cavity 101. These two clamping grooves 102 can be snap-connected to the two cards 401 on the filter tip 4. In this way, when the tool body 1 is rotated, the filter tip 4 can be driven to rotate as a whole through the cards 401, so as to disassemble the filter tip 4. The force application points during rotation are all concentrated on the cards 401, so the air inlet of the filter tip 4 will not be damaged.

[0029] At the top of the tool body 1, there is an insertion hole 104. The cross-sectional shape of the insertion hole 104 is polygonal, and in this embodiment, it is a regular hexagon. A rotating rod 2 is inserted into the insertion hole 104. The rotating rod 2 is a prism with a regular hexagon cross-sectional shape. By screwing the rotating rod 2 with a wrench, the tool body 1 is driven to rotate, and then the filter tip 4 is driven to rotate, and finally the filter tip 4 can be quickly disassembled.

[0030] In this embodiment, the insertion hole 104 is a blind hole, so that after the rotating rod 2 is inserted into the insertion hole 104, it will not penetrate into the cavity 101 and damage the air inlet of the filter tip 4.

[0031] Reference Figure 3 , in this embodiment, there is a through hole 201 penetrating up and down in the middle of the rotating rod 2. At the same time, there is an air outlet hole 103 in the insertion hole 104. The air outlet hole 103 can communicate the insertion hole 104 with the cavity 101. The excess gas in the air sampler 3 can be discharged through the air outlet hole 103 and the through hole 201 on the rotating rod 2.

[0032] A flange portion 105 is formed by protruding outward at the top of the tool body 1, making the top of the tool body 1 thicker, so that after rotating in place, the tool body 1 can be manually pulled off from the filter tip 4.

[0033] Embodiment 2

[0034] As Figure 6 shown, the difference between this embodiment and Embodiment 1 is that no rotating rod 2 is provided in the insertion hole 104 of the tool body 1, and the structures of other parts are the same as those in the embodiment. During disassembly, only an inner hexagon wrench needs to be inserted into the insertion hole 104, and then the wrench is rotated to drive the tool body 1 to rotate, and then the filter tip 4 is driven to rotate, and finally the filter tip 4 can be quickly disassembled from the air sampler 3.

[0035] Embodiment 3

[0036] As Figure 7 shown, the difference between this embodiment and Embodiment 1 is that no insertion hole 104 and rotating rod 2 are provided on the tool body 1, and only the through hole 201 for exhaust is retained, and the exhaust hole penetrates upward to the top surface of the tool body 1. The difference is that an external hexagon is provided on the upper part of the tool body 1, that is, the external contour shape of the upper part of the tool body 1 is a regular hexagon. In this way, only need to clamp the upper part of the tool body 1 with a wrench and then turn the wrench to drive the tool body 1 to rotate, and then drive the filter tip 4 to rotate, and finally the filter tip 4 can be quickly disassembled from the air sampler 3.

[0037] Embodiment 4

[0038] As Figure 8As shown, the difference between Example 1 and the embodiment lies in that an insertion hole 104 and a rotating rod 2 are also provided on the tool body 1, and only the through hole 201 for exhaust is retained. There is a handle 11 on the outer side of the tool body 1, and the handle 11 is integrally formed with the tool body 1. By turning the handle 11, the tool body 1 is driven to rotate, and then the filter tip 4 is driven to rotate, and finally the filter tip 4 is quickly disassembled from the air sampler 3.

[0039] The above technical solution only reflects the preferred technical solution of the technical solution of the present utility model. Some changes that those skilled in the art may make to some parts thereof all reflect the principle of the present utility model and fall within the protection scope of the present utility model.
