[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1-7 As shown, this utility model embodiment provides an air purification and environmental protection device, including a lower housing 10 and an upper housing 11;

[0036] In one embodiment, a filter screen 14 is detachably installed inside the lower housing 10, and an air inlet 13 communicating with the interior is opened on its outer side wall; an air outlet 30 is opened on the top wall of the upper housing 11, and a negative pressure fan 18 is fixedly installed inside it; a slot 19 is opened on the side of the upper housing 11 near the lower housing 10; a fixing plate 20 for interlocking with the slot 19 is fixedly connected to the lower housing 10; symmetrically distributed cavities 21 are provided in the fixing plate 20; through grooves 24 are opened on opposite sides of the two cavities 21; a movable plate 22 is slidably connected inside the cavity 21; a return spring 23 is fixedly connected to one side of the movable plate 22; the other end of the return spring 23 is fixedly connected to the inner wall of the cavity 21; an arc-shaped block 25 is fixedly connected to the other side of the movable plate 22; the arc-shaped block 25 slides along the inner side wall of the through groove 24; equidistantly distributed arc-shaped grooves 101 are opened on the inner wall of the slot 19; the arc-shaped end of the arc-shaped block 25 abuts against the inner wall of the arc-shaped groove 101.

[0037] When it is necessary to connect the upper housing 11 and the lower housing 10, the fixing plate 20 of the lower housing 10 is aligned with the slot 19 of the upper housing 11 and inserted. At this time, the arc-shaped end of the arc-shaped block 25 contacts the inner wall of the slot 19 and is squeezed. The arc-shaped block 25 compresses the return spring 23 through the movable plate 22 and retracts into the cavity 21. When the fixing plate 20 is inserted to the appropriate position, the arc-shaped block 25 pops out along the through groove 24 under the elastic force of the return spring 23, and its arc-shaped end abuts against the arc groove 101 of the inner wall of the slot 19, so as to achieve quick fixation of the upper housing 11 and the lower housing 10. During disassembly, simply apply external force upwards or downwards to separate the upper housing 11 and the lower housing 10. The arc-shaped block 25 will then be compressed and retracted, disengaging from the arc-shaped groove 101, thus completing the disassembly. Through the cooperation of the return spring 23 with the arc-shaped block 25 and the arc-shaped groove 101, tool-free quick disassembly and assembly of the upper housing 11 and the lower housing 10 are achieved, simplifying the maintenance and repair process of the internal components of the equipment. At the same time, it facilitates the timely replacement of the filter screen 14, greatly improving the ease of use of the equipment.

[0038] In one embodiment, the fixed plate 20 has a slot 28, and the inner top wall of the slot 19 is fixedly connected to a plug 102 that engages with the slot 28; there are two plugs 102, and each of the two plugs 102 has a protrusion 103 integrally formed on its opposite side; the inner wall of the slot 28 has symmetrically formed grooves 29 for the protrusions 103 to be inserted into. The cavity 21 has symmetrically formed sliding grooves 27, and both sides of the movable plate 22 are fixedly connected to sliders 26, which slide in cooperation with the inner sidewall of the sliding groove 27;

[0039] During the insertion of the fixed plate 20 into the slot 19, the insert block 102 is simultaneously inserted into the slot 28. When the insert block 102 is fully inserted into the slot 28, the protrusion 103 on the insert block 102 is embedded in the groove 29 on the inner wall of the slot 28 due to its own elastic deformation, forming a secondary fixation. At the same time, when the movable plate 22 slides in the cavity 21, the sliders 26 on both sides slide synchronously along the slide groove 27, guiding and limiting the movement trajectory of the movable plate 22. The cooperation between the insert block 102 and the slot 28, and the protrusion 103 and the groove 29, further enhances the stability of the shell connection based on the arc block 25 and the arc groove 101, effectively preventing loosening or displacement after long-term use of the equipment. The sliding cooperation between the slider 26 and the slide groove 27 ensures the smooth movement of the movable plate 22 in the cavity 21, avoiding tilting or jamming of the movable plate 22 due to uneven force, and improving the reliability and service life of the overall structure.

[0040] In one embodiment, a circular channel 31 is provided inside the upper housing 11 near the air outlet 30. A plurality of baffles 32 are slidably connected to the inner wall of the circular channel 31. A linkage disc 33 is fixedly connected to one side of each baffle 32. An adjusting roller 34 is coaxially fixedly connected to one side of the linkage disc 33. One end of the adjusting roller 34 passes through the upper housing 11 and is fixedly connected to a knob 35. The outer circumferential surface of the adjusting roller 34 has a knurled structure. The number of baffles 32 corresponds to and matches the number of air outlets 30, and the projected area of ​​a single baffle 32 is not less than the cross-sectional area of ​​the corresponding air outlet 30.

[0041] When it is necessary to adjust the airflow volume of the air outlet 30, turn the knob 35. The knob 35 drives the adjusting roller 34 to rotate synchronously. The adjusting roller 34 drives the linkage disc 33 to rotate, which in turn drives all the baffles 32 to slide along the inner wall of the circular channel 31. During the sliding process, the relative position of the baffles 32 with the air outlet 30 changes, thereby adjusting the opening size of the air outlet 30. The knurled structure of the adjusting roller 34 increases the friction, making it easy to keep stationary after force is applied and rotation is performed. The opening size of the air outlet 30 can be directly adjusted by the baffles 32, which can be coordinated with the speed adjustment of the negative pressure fan 18 to achieve precise control of the airflow volume and airflow range, and can flexibly adapt to the needs of different space sizes or usage scenarios. The number of baffles 32 corresponds to the air outlet 30 and the projected area of ​​each baffle 32 is sufficient to ensure the effectiveness of the adjustment. The design of the knob 35 and the knurled structure of the adjusting roller 34 improves the convenience of operation, and the adjustment can be completed without complicated steps.

[0042] In one embodiment, an elastic sealing gasket 16 is embedded at the top edge of the lower housing 10, and the top of the elastic sealing gasket 16 abuts against the bottom edge of the upper housing 11 to form a seal. The filter screen 14 includes a pre-filter, an activated carbon filter, and a HEPA filter stacked sequentially. A control panel 17 is fixedly installed on the outer side wall of the upper housing 11. The control panel 17 is electrically connected to the negative pressure fan 18, and the control panel 17 is provided with an adjustment button for adjusting the speed of the negative pressure fan 18 and an operating status indicator light.

[0043] After the upper housing 11 and the lower housing 10 are connected and fixed, the elastic sealing gasket 16 on the top of the lower housing 10 deforms due to compression and fills the edge gap between the two housings, blocking the path of unfiltered air leakage from the gap. After the air enters the lower housing 10 from the air inlet 13, it passes through the pre-filter, activated carbon filter and HEPA filter in the filter screen 14 in sequence to complete the purification, and finally is discharged from the air outlet 30 under the action of the negative pressure fan 18. The user can change the speed of the negative pressure fan 18 through the adjustment button on the control panel 17, thereby adjusting the purification and air output efficiency. The operating status indicator on the control panel 17 displays the working status of the device in real time. The elastic sealing gasket 16 effectively improves the sealing performance of the housing, preventing unfiltered air from bypassing the filter screen 14 and being discharged directly, ensuring purification efficiency. The multi-layer stacked combination of the filter screen 14 can remove different types of air pollutants in a targeted manner, greatly improving the comprehensiveness and depth of air purification. The setting of the control panel 17 makes the device operation more intuitive and convenient. Users can flexibly adjust the operating parameters according to their needs, and at the same time, they can keep track of the device status in real time through the indicator lights, improving the user experience.

[0044] In operation, the user starts the device via control panel 17, and the negative pressure fan 18 begins to run, creating a negative pressure environment inside the device. External air enters the lower housing 10 through the air inlet 13 on the outer wall of the lower housing 10 due to the pressure difference. The incoming air first flows through the detachable filter 14, then through a pre-filter to remove large particles such as dust and hair, followed by an activated carbon filter to adsorb odors and harmful gases such as formaldehyde, and finally through a HEPA filter to remove fine particulate matter such as PM2.5, completing multi-layer purification. The purified air then flows upward under the action of the negative pressure fan 18, entering the upper housing 11, and finally exiting through the air outlet 30 on the top wall, achieving indoor air purification and circulation.

[0045] To adjust the airflow, the knob 35 can be turned to rotate the adjusting roller 34 and the linkage disc 33, causing the baffle 32 to slide along the circular groove 31, changing its relative position with the air outlet 30, thereby adjusting the opening size of the air outlet 30. Simultaneously, the speed of the negative pressure fan 18 can be changed using the adjustment buttons on the control panel 17. The combination of these two methods allows for precise control of the airflow. The operating status indicator light displays the equipment's working status in real time, allowing users to easily monitor its operation.

[0046] When it is necessary to replace the filter 14 or maintain internal components, simply apply external force to separate the upper housing 11 from the lower housing 10. At this time, the arc-shaped block 25 on the fixing plate 20 is squeezed, compressing the return spring 23 and retracting into the cavity 21, disengaging from the arc-shaped groove 101 on the inner wall of the slot 19. The protrusion 103 on the insert block 102 also disengages from the groove 29 of the slot 28, thus separating the two parts. The operation is convenient and requires no tools. During installation, the fixing plate 20 is inserted into the slot 19. Under the action of the return spring 23, the arc-shaped block 25 is engaged in the arc-shaped groove 101, and the protrusion 103 is embedded in the groove 29, achieving a stable connection. At the same time, the elastic sealing gasket 16 on the top of the lower housing 10 abuts against the bottom of the upper housing 11 to form a seal, preventing unfiltered air leakage and ensuring the purification effect.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
