[0027] Figure 1 is a schematic structural diagram of the air purification device with filter screen easy to disassemble, likeFigure 1 The utility model discloses an air purification device of filter screen easy to disassemble, and the air purification device of filter screen easy to disassemble comprises a shell, a plurality of filter screens 200, a push rod 410, an elastic piece 420 and an access door 320. Figures 2 to 3 The shell 100 is provided with a mounting port, and the plurality of filter screens 200 are sequentially arranged from left to right, and the filter screens 200 are slidingly inserted into the shell 100 through the mounting port.

[0028] The push rod 410 is arranged in the shell 100 and extends along the left-right direction and abuts against the inner end edge of the filter screen 200, and one end of the push rod 410 is hingedly connected to the shell 100. The elastic piece 420 is used for connecting the other end of the push rod 410 to the shell 100, and is configured to move the other end of the push rod 410 outward when the elastic force is released. The access door 320 is mounted on the shell 100 and is used for controlling the opening and closing of the mounting port, so that the elastic piece is retracted and stored when the access door 320 is in the locked state.

[0029] Specifically, the access door 320 and the mounting port are sealingly matched to ensure the sealing property of the shell 100. Further, in the initial state, the push rod 410 is perpendicular to the filter screen 200, and when the other end of the push rod 410 moves outward, the push rod 410 gradually tilts outward, and at this time, the other end of the push rod 410 is located outside one end of the push rod 410. During the tilting of the push rod 410, the plurality of filter screens 200 are gradually moved outward, so that the filter screen 200 close to the other end of the push rod 410 is first pushed outward, and thus the plurality of filter screens 200 are sequentially pushed outward from left to right.

[0030] Further, since the push rod 410 is in the tilted state, the distance of each filter screen 200 moving outward from left to right gradually decreases, so that the single filter screen 200 can be conveniently taken and disassembled, and thus the replacement efficiency of the filter screen 200 can be improved, and the filter screen 200 can be conveniently maintained, repaired and replaced, and thus the practicability of the device is increased. Further, the elastic piece 420 pushes the other end of the push rod 410 outward through the elastic force, and when the filter screen 200 is inserted inward, the filter screen 200 pushes the push rod 410 to rotate inward, so that the elastic piece 420 is retracted and stored. Further, one vertical edge of the access door 320 is rotatably mounted on the shell 100 through the hinge plate 330.

[0031] When the filter screen 200 needs to be disassembled, the maintenance door 320 is opened first, and in the process of opening, the elastic member 420 releases the elastic force and pushes the other end of the push rod 410 outward, so that the push rod 410 rotates outward. In the process of rotating outward, the plurality of filter screens 200 are pushed to move outward in turn from left to right. As the opening angle of the maintenance door 320 increases, the elastic force released by the elastic member 420 gradually increases, so that the angle of the push rod 410 rotating outward increases, until the maintenance door 320 is completely opened, and the elastic member 420 is completely released, so that the plurality of filter screens 200 are arranged in a stepped manner and extend outward from the installation opening.

[0032] The filter screen 200 extending outward is disassembled and replaced, and after the replacement of the filter screen 200 is completed, the maintenance door 320 is pushed inward to close. The maintenance door 320 pushes the filter screen 200 inward to apply a pushing force to the filter screen 200, so that the filter screen 200 moves inward. The filter screen 200 moves inward to push the push rod 410 to rotate inward, so that the elastic member 420 retracts and accumulates the elastic force. When the filter screen 200 is completely installed in the housing 100, the maintenance door 320 is locked and closed, and the replacement or maintenance work of the filter screen 200 is completed.

[0033] In the embodiment, the inner side wall of the housing 100 is provided with a hinge seat 411, and one end of the push rod 410 is hinged to the hinge seat 411, so that the push rod 410 rotates in the housing 100.

[0034] In the embodiment, when the maintenance door 320 is closed, the inner side surface thereof abuts against the outer end edge of the filter screen 200, so as to prevent the filter screen 200 from shaking, thereby providing stability for the installation of the filter screen 200. Further, the inner side surface of the maintenance door 320 is a rubber surface.

[0035] In some embodiments of the utility model, as shown in Figure 2 and Figure 3 The filter screen easy-to-disassemble air purification device further comprises a top rod 430, the top rod 430 is slidably inserted into the housing 100, one end of the top rod 430 abuts against the push rod 410, and the other end of the top rod 430 abuts against the maintenance door 320.

[0036] Specifically, when the other end of the push rod 410 moves outward, the other end of the top rod 430 is pushed to extend out of the installation opening. When the top rod 430 moves outward, the other end of the push rod 410 is pushed to move inward synchronously, so that the elastic member 420 retracts and accumulates the elastic force. Since the other end of the push rod 410 abuts against the top rod 430, the maintenance door 320 can be easily and labor-savingly closed.

[0037] In some embodiments of the utility model, as shown in Figure 1 and Figure 2As shown, the shell 100 is provided with a plurality of sliding rails, each filter screen 200 is detachably mounted on a sliding rail, so that the filter screen 200 can be pulled and slid in the shell 100. A preset damping is arranged between the filter screen 200 and the sliding rail, and the preset damping is used to make the filter screen 200 slide uniformly on the sliding rail.

[0038] Specifically, the arrangement of the sliding rail can increase the stability during the insertion of the filter screen 200. Further, the preset damping can provide resistance to the outward sliding of the filter screen 200, and the arrangement of the preset damping can prevent the elastic member 420 from instantaneously releasing the elastic force to pop out the filter screen 200 outward, thereby making the filter screen 200 move outward at a uniform speed.

[0039] In some embodiments of the utility model, the elastic member 420 is a damping spring structure.

[0040] In some embodiments of the utility model, as shown in Figure 2 The elastic member 420 is a spring, one end of the spring is fixedly connected with the push rod 410, and the other end is fixedly connected with the inner wall of the shell 100. Specifically, the spring is in a compressed and stored state in the initial state, when the spring releases the elastic force, the other end of the push rod 410 is pushed outward by the spring, thereby making the push rod 410 rotate outward.

[0041] In some embodiments of the utility model, as shown in Figure 2 And Figure 3 As shown, the shell 100 is provided with an air inlet 110 and an air outlet 140, and the air outlet 140 is provided with a flow distribution assembly.

Further, the flow distribution assembly can diffuse the purified air discharged outward from the air outlet 140 to the surrounding, thereby being capable of quickly improving the surrounding air quality. Further, the flow distribution assembly is a back-shaped flow distributor.

[0043] In some embodiments of the utility model, each filter screen 200 filters a target object, and each target object is different. Specifically, the arrangement of each filter screen 200 for filtering a different target object can filter various impurities in the air to purify the air. Specifically, the arrangement of a plurality of filter screens 200 is different from the integrated single filter screen 200 which filters a plurality of target objects at a time, thereby being capable of preventing the filter screen 200 from being overloaded during filtering, thereby increasing the effective filtering time of the filter screen 200 and improving the efficiency of filtering air.

[0044] In the embodiment, the number of the filter screens 200 is at least three, and the three filter screens 200 are respectively a first filter screen, a second filter screen and a third filter screen. The first filter screen is used for filtering a first target object. The second filter screen is used for filtering a second target object. The third filter screen is used for filtering a third target object. Specifically, the first target object is dust particles; the second target object is oil stains; and the third target object is odor molecules.

[0045] Further, the filter holes on the third filter screen are in a honeycomb shape, and each filter hole is filled with high-efficiency odor-removing activated carbon particles. Specifically, the filter holes in the honeycomb shape have the advantages of high adsorption efficiency, small wind resistance and low energy consumption. The high-efficiency odor-removing activated carbon particles can effectively remove harmful gases in the air.

[0046] Further, the plastic honeycomb of the filter hole structure of the third filter screen is a carrier, and is filled with high-efficiency catalytic spherical activated carbon particles. The activated carbon particles are designed on the basis of previous adsorption materials by using a design concept of "chemical adsorption + catalytic decomposition", and by introducing catalytic functional groups on the surface, the activated carbon particles have a qualitative change effect of "chemical adsorption + catalytic decomposition" on pollutants in space, so that the pollutants are changed into non-toxic and harmless substances, the purification function is more powerful, and no secondary pollution is generated, so that the effect of environmental protection and reliability is achieved.

[0047] In some embodiments of the utility model, the air purification device with filter screens easy to disassemble further includes a vibration assembly, the vibration assembly is connected with the plurality of filter screens 200 to drive the plurality of filter screens 200 to vibrate. The vibration assembly is configured to drive the plurality of filter screens 200 to vibrate once every preset time.

[0048] Specifically, one vibration of the filter screen 200 is a fixed time period, and the filter screen 200 continuously vibrates to shake off the filtered objects on the filter screen 200 within the time period. Further, the vibration assembly drives the filter screen 200 to vibrate, which can shake off the target objects on the filter screen 200, so that the cleaning operation of the filter screen 200 can be completed, and the filter screen 200 can maintain a good filtering state for filtering work, thereby improving the filtering efficiency and prolonging the service life of the filter screen 200.

[0049] In some embodiments of the utility model, as shown in Figure 1 and Figure 2 As shown, the shell 100 is provided with a plurality of rotating blocks 310, the rotating blocks 310 are rotatably arranged, and the rotating blocks 310 can be rotated to the front side of the installation opening, so that when the access door 320 closes the installation opening, the rotating blocks 310 can abut against the outside of the access door 320.

[0050] Specifically, the rotating block 310 is provided with a rotating shaft, and the rotating block 310 is rotatably arranged on the shell 100 through the rotating shaft. Further, the rotating shaft is fixed on the shell 100, and the surface of the rotating block 310 capable of abutting against the inspection door 320 is an abutting surface, and the abutting surface is provided with rubber. The abutting surface is in interference fit with the inspection door 320, so that the abutting force of the rotating block 310 on the inspection door 320 can be increased, thereby preventing the inspection door 320 from shaking and increasing the stability of the inspection door 320 in the closed state. Further, the rotating block 310 is provided with a flat head, and the flat head can be conveniently operated by hand, so that the rotating block 310 can be rotated.
