Description

Technical Field

[0001] The utility model relates to the technical field of air detection, in particular to an anti-false detection curtain for air filter element detection. Background Art

[0002] Some industries have high requirements for indoor air purification, such as pharmaceutical production workshops that require sterilization and dust-free workshops that produce precision electronic equipment. Therefore, it is necessary to regularly inspect the air filters of their air purification equipment to prevent outside air with a large amount of impurities from entering the room.

[0003] Usually when testing the air filter element of the filter, it is necessary to deliver test smoke to the air channel with the air filter element. A rigid filter is generally provided at the air outlet end of the air channel. Therefore, during the test, the handheld end of the handheld filter testing device generally covers a part of the air outlet end of the air channel, and waits for the filter testing device to judge the result. After the test result is normal, it is transferred to another area of ​​the air outlet end of the air channel for testing. The testing route is S-shaped until, after multiple tests, the test area completely covers the entire air channel, completing the test of the entire air filter element.

[0004] However, during the current detection, since the air outlet end of the air channel is completely connected to the indoor room, the air can flow freely. The filtered air in the room can easily flow through the handheld end of the filter detection device, causing the filter detection device to misjudge that the filtration performance of the air filter element in this area is normal, making the detection result of the filter detection device unreliable, affecting the degree of indoor air purification.

[0005] Based on the above background, the inventor has designed an anti-false detection curtain for air filter element detection to solve the above problems, and thus proposed this application. Summary of the Invention

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] Example 1:

[0037] like Figures 1 to 4 As shown, this embodiment provides an anti-false detection curtain for detecting an air filter element 6, comprising a curtain body 1 for blocking indoor air from flowing into the vicinity of a detection position, and a shaping frame 2 for shaping and mounting at the filter element detection position, wherein:

[0038] The shape of the shaping frame 2 and the cross-sectional shape of the curtain body 1 are both annular, and the top end of the curtain body 1 is fixedly connected to the shaping frame 2 .

[0039] In order to solve the problem that the purified air in the room may flow directly to the vicinity of the detection position, this embodiment provides a shaping frame 2 and a curtain body 1. Before the detection, the curtain body 1 can be installed on the channel of the filter element to be detected through the shaping frame 2, forming a barrier between the purified air in the room and the detection position to prevent the purified air in the room from flowing directly to the vicinity of the detection port of the detection device for the air filter element 6, thereby ensuring the accuracy of the detection results of the detection device for the air filter element 6.

[0040] Specifically, in this embodiment, Figures 1 to 3 As shown, the quick-install structure further includes a quick-install structure for quickly disassembling and assembling the shaping frame 2, and the quick-install structure is arranged on the side of the shaping frame 2 away from the curtain body 1. By arranging the quick-install structure, the installation speed of the shaping frame 2 can be accelerated.

[0041] Specifically, in the embodiment, Figures 1 to 3 As shown, the quick-install structure is a permanent magnet 3;

[0042] The forming frame 2 is provided with a mounting groove 21, and the permanent magnet 3 is installed and fixed in the mounting groove 21. Generally speaking, the rigid filter screen 5 is generally made of steel. Therefore, the permanent magnet 3 is provided, and the forming frame 2 and the curtain body 1 can be adsorbed onto the rigid filter screen 5 through the permanent magnet 3, which greatly simplifies the installation process of the forming frame 2.

[0043] In an optional embodiment, the shape of the forming frame 2 is any one of a square ring, a circular ring, and an elliptical ring. In this embodiment, the forming frame 2 is a square ring, so as to better match the rigid filter screen. Technicians can also set the shape of the forming frame 2 to other shapes such as a circular ring, an elliptical ring, etc. as needed, which will not be repeated here.

[0044] In this embodiment, Figures 1 to 4 As shown, a closing structure 11 for closing the bottom end of the curtain body 1 is provided at the bottom of the curtain body 1 away from the forming frame 2. The setting of the closing structure 11 can prevent indoor air from flowing from the bottom to the vicinity of the detection position, which can further reduce the probability of error in the detection results of the detection device.

[0045] In this embodiment, Figures 1 to 4The closing structure 11 is a rope-threading closing structure 11;

[0046] The closing rope 4 is provided in the threading closing structure 11. The threading closing structure 11 and the threading closing rope 4 allow the operator to simply pull the threading closing rope 4 to complete the closing, which is simple to operate. In this embodiment, the handheld detection device can be passed through the threading closing structure 11 at the bottom of the curtain body 1 to the vicinity of the detection position.

[0047] In this embodiment, the curtain body 1 is made of any one of polyethylene material, polypropylene material, and polyester material. In this embodiment, the curtain body 1 is made of polyethylene material. Technicians can choose polypropylene material, polyester material or other air-leakage-proof materials as needed.

[0048] In this embodiment, the top end of the curtain body 1 and the bottom end of the shaping frame 2 are detachably fixedly connected, so that the curtain body 1 can be easily replaced.

[0049] In this embodiment, an adhesive layer is provided on the top of the curtain body 1;

[0050] The top of the curtain body 1 is bonded and fixed to the shaping frame 2. After the curtain body 1 is used multiple times or for a long time, the curtain body 1 can be directly torn off from the shaping frame 2 and replaced, thereby reducing the use cost.

[0051] Example 2:

[0052] like Figure 5 As shown, in this embodiment, it also includes an air leakage-proof zipper 7 provided between the top end of the curtain body 1 and the bottom end of the shaping frame 2;

[0053] The air leakage-proof zipper 7 includes a first chain tooth 71 and a second chain tooth 72 respectively arranged at the top end of the curtain body 1 and the bottom end of the shaping frame 2, and a slider (not shown in the figure) arranged on the first chain tooth 71 or the second chain tooth 72.

[0054] The air leakage-proof zipper 7 in this embodiment is used to connect the curtain body 1 and the shaping frame 2, and its function is the same as that of the adhesive layer in Example 1. The air leakage-proof zipper 7 is an existing part, and its specific structure is not described here.

[0055] The rest of the structure of this embodiment is the same as that of the above-mentioned embodiment 1 and will not be described again here.

[0056] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art will be able to make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
