[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0028] In one embodiment, such as Figures 1-6As shown, an easy-to-maintain air quality detection device includes a detector body 1. The top of the detector body 1 is provided with an air inlet 4, and the side of the detector body 1 is provided with an air outlet 17. The upper part of the front of the detector body 1 is provided with a touch screen panel 2, and the lower side of the touch screen panel 2 is provided with a control panel 3. The detector body 1 is provided with an air pump 18 near the air inlet 4, and the back of the detector body 1 is provided with a winding box 5. The suction end of the air inlet 4 is connected to an air extraction hose 8, and the other end of the air extraction hose 8 is rotatably mounted with a winding mechanism, which is located inside the winding box 5.
[0029] In this embodiment, the air pump 18 is activated and the air inlet 4 begins to draw in the air to be detected. The air inlet 4 is connected to the winding mechanism through the air extraction hose 8, so that the device can be adapted to air detection in narrow and deep spaces.
[0030] In one embodiment, such as Figure 2 As shown, the winding mechanism includes a winding roller 9, which has a hollow structure. A winding hose 12 is wound around the surface of the winding roller 9. The fixed end of the winding hose 12 is connected to the winding roller 9. An exhaust port is provided at the shaft end of the winding roller 9. The exhaust port is rotatably connected to the end of an air extraction hose 8. The end of the air extraction hose 8 is fixedly connected to a winding box 5. The winding roller 9 is rotatably connected inside the winding box 5. A rotating assembly 10 is connected to the middle of the bottom of the winding roller 9 through the winding box 5. A handle 11 is provided at the bottom of the rotating assembly 10. By holding the handle 11 and rotating the rotating assembly 10, the winding roller 9 can be rotated to retract the winding hose 12.
[0031] In one embodiment, such as Figure 3 As shown, a locking block 13 is provided on the back of the detector body 1, and a locking slot 14 corresponding to the locking block 13 is provided on the side of the winding box 5 near the detector body 1. The winding box 5 is a detachable structure and can be disassembled if it is not required to detect special environments.
[0032] In one embodiment, such as Figure 4 As shown, the air inlet 4 and the suction hose 8 are connected by an upper fixing member 7 and a lower fixing member 16. A sealing ring 15 is provided at the bottom of the upper fixing member 7. The suction hose 8 and the air inlet 4 can also be detached. When it is not necessary to test special environments, the suction hose 8 and the winding box 5 can be detached, and normal testing can be performed only through the air inlet 4.
[0033] In one embodiment, such as Figure 5 As shown, the inner wall of the air inlet 4 is provided with a filter plate groove 401, a pair of sliding grooves 403 are provided on both sides of the filter plate groove 401, a pair of fixing grooves 402 are provided on the top of the inner wall of the filter plate groove 401, and a slot for placing the filter mechanism 6 is provided inside the air inlet 4.
[0034] In one embodiment, such as Figure 5 As shown, a filter mechanism 6 is snapped into the filter plate groove 401. The filter mechanism 6 is used to filter dust entering the device to ensure the quality of the test.
[0035] In one embodiment, such as Figure 5 and Figure 6 As shown, the filtering mechanism 6 includes a filter plate 601. The inner wall of the filter plate 601 is provided with a filter screen 602 corresponding to the air intake pipe. The two sides of the filter plate 601 are provided with sliders 603 corresponding to the slide grooves 403. A fixing plate 605 is fixedly connected to the top of the inner wall of the filter plate 601. A groove 604 is opened on the top of the filter plate 601. A pair of locking mechanisms are symmetrically arranged on both sides of the fixing plate 605. The sliders 603 are aligned with the slide grooves 403, and the filter plate 601 is inserted into the filter plate grooves 401.
[0036] In one embodiment, such as Figure 5 and Figure 6 As shown, the locking mechanism includes a spring 608, a connecting block 607 connected to one side of the spring 608, a locking block 606 connected to one side of the connecting block 607 through the filter plate 601, and a push block 609 connected to the top of the connecting block 607 through the filter plate 601. The push block 609 is slidably connected in the groove 604. Pushing the two push blocks 609 with protrusions on the top towards the middle causes the locking block 606 to retract, releasing the engagement with the fixing groove 402, thus allowing the filter plate 601 to be disassembled quickly, avoiding dust accumulation and reducing the number of maintenance operations inside the device. During installation, when the filter plate 601 is pushed back, the locking block 606 automatically retracts under the action of the spring 608 when it contacts the inclined surface above the fixing groove 402, and automatically pops out after entering the fixing groove 402, completing the fixing.
[0037] The above embodiment discloses an easy-to-maintain air quality detection device. When the air intake pump 18 is activated, the air intake port 4 begins to draw in the air to be tested. The air intake port 4 is connected to the winding mechanism via the suction hose 8. The winding hose 12 is then placed in a confined space for air testing. After testing, the operator rotates the rotating assembly 10 by holding the handle 11, causing the winding roller 9 to rotate and retract the winding hose 12. The operator operates the detector body 1 and observes the test results via the touchscreen panel 2 and control panel 3. The air after testing is discharged through the air outlet 17. Due to the design of the slot 14 and the locking block 13, the winding box 5 is a detachable structure. It can be disassembled if testing in special environments is not required. The suction hose 8 can also be removed by removing the upper fixing part 7 and the lower fixing part 16. The device can be used for normal testing only through the air inlet 4, making it suitable for both confined and deep environments as well as daily use. The air inlet 4 is equipped with a filter mechanism 6 to filter dust entering the device, ensuring testing quality. During installation, align the slider 603 with the slide groove 403, insert the filter plate 601 into the filter plate groove 401, and when the locking block 606 contacts the inclined surface above the fixing groove 402, it automatically retracts under the action of the spring 608, automatically popping out after entering the fixing groove 402, thus completing the fixing. During disassembly, push the two side push blocks 609 with protrusions on the top towards the middle, causing the locking block 606 to retract and release the engagement with the fixing groove 402, allowing the filter plate 601 to be removed quickly, preventing dust accumulation and reducing the frequency of maintenance inside the device.
