[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up an installation device, when the equipment is in use, the user pulls the connecting block to the left, and the connecting block drives the stop bar, which moves out of the surface of the connecting plate. At the same time, the connecting block slides along the surface of the limiting rod, and the first spring is stretched and deformed. At this time, the user pulls the handle, and the handle drives the rotating rod to rotate. The torsion spring is stretched and deformed, and then the handle and the filter plate are in a horizontal state. Then, by pulling the handle, the filter plate can be easily removed. By setting up an installation device, the filter plate can be effectively installed and disassembled, which improves the convenience of filter plate maintenance. When using general equipment, the operation of installing and replacing the filter plate is complicated, which not only consumes a lot of time for the user, but may also damage the equipment due to improper operation.

[0015] 2. In this utility model, by setting a protective device, when the device is in use, the user pulls the fixing bar upwards, and the fixing bar then drives the fixing rod to detach from the fixing block and the inner wall of the fixing plate. At the same time, the fixing bar drives the sliding rod to slide upwards, and the second spring is subsequently deformed by the force. At this time, the protective plate is pushed, and the slider slides downwards on the inner wall of the device body. By setting a protective device, the air outlet is effectively protected, which reduces the air outlet from being blocked by foreign objects when the device is not in use. Generally, if the air outlet of a device is not covered when it is not in use, it is easily blocked by dust and debris, which affects the air output efficiency and purification effect of the device, and increases the frequency and cost of maintenance. This protective device effectively extends the service life of the air purifier and improves the practicality of the device. Attached Figure Description

[0028] The effect achieved by the above components is that by setting the limiting strip 52, it is convenient to limit the filter plate 51.

[0029] Specifically, a handle 56 is fixedly connected to one end of the rotating rod 55, a torsion spring 57 is sleeved and connected to the surface of the rotating rod 55, one end of the torsion spring 57 is fixedly connected to the upper surface of the mounting base 54, the end of the torsion spring 57 away from the mounting base 54 is fixedly connected to the surface of the handle 56, and a mounting block 58 is fixedly connected to the side of the equipment body 1.

[0030] The effect achieved by the above components is that by setting the torsion spring 57, the pull handle 56 can be attached to the connecting plate 53 when not in use.

[0031] Specifically, a stop bar 59 is slidably connected to the inner wall of the mounting block 58. One end of the stop bar 59 abuts against the surface of the connecting plate 53, and a connecting block 510 is fixedly connected to the end of the stop bar 59 away from the connecting plate 53.

[0032] The effect achieved by the above components is that by setting the baffle 59, it is easy to abut the connecting plate 53 and prevent the filter plate 51 from moving outward from the inner wall of the main body 1.

[0033] Specifically, a limiting rod 511 is fixedly connected to the lower surface of the mounting block 58, and the connecting block 510 is slidably connected to the surface of the limiting rod 511. A first spring 512 is sleeved and connected to the surface of the limiting rod 511. One end of the first spring 512 is fixedly connected to the lower surface of the mounting block 58, and the end of the first spring 512 away from the mounting block 58 is fixedly connected to the surface of the connecting block 510.

[0034] The effect achieved by the above components is that by setting the limit rod 511, it is easy to accurately constrain the sliding trajectory of the connecting block 510.

[0035] Specifically, a protective device 6 is provided above the air outlet 4. The protective device 6 includes a protective plate 61 and a slider 62. The protective plate 61 is provided above the air outlet 4. The slider 62 is slidably connected to the inner wall of the side of the equipment body 1. A limit block 63 is fixedly connected to the surface of the slider 62. A slide rail 64 is provided on the inner wall of the equipment body 1. The limit block 63 is slidably connected to the slide rail 64.

[0036] The effect achieved by the above components is that by setting up the protective plate 61, the air outlet 4 can be protected, preventing debris from accumulating and causing blockage of the air outlet 4.

[0037] Specifically, a fixing plate 65 is fixedly connected to the end of the protective plate 61 away from the slider 62, a fixing block 66 is fixedly connected to the side of the main body 1 of the equipment, and a fixing rod 67 is connected through the inner wall of the fixing plate 65.

[0038] The effect achieved by the above components is that by setting the fixing plate 65, it is convenient to provide additional fixing points for the protective plate 61.

[0039] Specifically, a fixing bar 68 is fixedly connected to the upper end of the fixing rod 67, and a sliding rod 69 is fixedly connected to the lower surface of the fixing bar 68. The sliding rod 69 is slidably connected to the inner wall of the fixing block 66. A second spring 610 is sleeved and connected to the surface of the sliding rod 69. One end of the second spring 610 is fixedly connected to the upper surface of the fixing block 66, and the end of the second spring 610 away from the fixing block 66 is fixedly connected to the lower surface of the fixing bar 68.

[0040] The effect achieved by the above components is that by setting the second spring 610, it is easy to realize the automatic return of the fixing rod 67.

[0041] Working principle: When using the equipment, the user pulls the connecting block 510 to the left. The connecting block 510 then moves the stop bar 59, which moves out of the surface of the connecting plate 53. Simultaneously, the connecting block 510 slides along the surface of the limiting rod 511, causing the first spring 512 to deform under tension. At this time, the user pulls the handle 56, which drives the rotating rod 55 to rotate. The torsion spring 57 deforms under tension, bringing the handle 56 and the filter plate 51 into a horizontal position. Pulling the handle 56 again allows the filter plate 51 to be easily removed. The installation device 5 effectively facilitates the installation and removal of the filter plate 51, improving the ease of maintenance. In general equipment, installing and replacing the filter plate 51 is complex, consuming a lot of the user's time and potentially damaging the equipment due to improper operation. Frequent disassembly and installation shorten the equipment's lifespan and increase maintenance costs. This installation device 5 effectively simplifies the filter plate 51 replacement process and improves the equipment's usability.

[0042] When the device is in use, the user pulls the fixing bar 68 upwards, which then causes the fixing bar 68 to detach the fixing rod 67 from the inner wall of the fixing block 66 and the fixing plate 65. At the same time, the fixing bar 68 causes the sliding rod 69 to slide upwards, and the second spring 610 deforms under the force. This pushes the protective plate 61, and the slider 62 slides downwards on the inner wall of the device body 1. By setting the protective device 6, the air outlet 4 is effectively protected, reducing the possibility of the air outlet 4 being blocked by foreign objects when the device is not in use. Generally, if the air outlet 4 is not covered when the device is not in use, it is easily blocked by dust and debris, affecting the air output efficiency and purification effect of the device, increasing the frequency and cost of maintenance. This protective device 6 effectively extends the service life of the air purifier and improves the practicality of the device.
