Description

Technical Field

[0001] This utility model relates to the field of fixed bracket technology, and in particular to a multi-layer air purifier filter core assembly. Background Technology

[0002] Air filters are designed to provide clean air that meets standards. Generally, ventilation filters capture and adsorb dust particles of different sizes in the air to improve air quality. They purify the air with low dust content and deliver it indoors to ensure the process requirements of clean rooms and the air cleanliness of general air-conditioned rooms.

[0003] In existing technologies, multi-layer air purifier filter components accumulate a lot of particulate impurities on the filter element during long-term air purification, which reduces the filter element's lifespan and requires replacement, increasing the cost of air purification. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing multi-layer air purifier filter components, where many particulate impurities adhere to the filter element during long-term air purification, leading to a reduced filter element lifespan and the need for replacement, thus increasing the cost of air purification. Therefore, this invention proposes a multi-layer air purifier filter component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer air purifier filter element assembly, comprising a filter element body and an activated carbon filter cartridge, wherein a fixing device is provided on the outside of the filter element body, the fixing device comprising a fixing ring and a filter cotton cartridge, the inner side of the fixing ring being fixedly connected to the filter element body, two vertical plates being fixedly connected to the top of the fixing ring, two round rods being slidably connected to one side of the vertical plates, a pull plate being fixedly connected to one end of the two round rods, a spring being sleeved on the arc surface of the round rods, the two ends of the two springs being fixedly connected to the pull plate and the vertical plate respectively, and an arc-shaped clamping plate being fixedly connected to one end of the round rods.

[0006] The effect achieved by the above components is as follows: the pull plate is moved away from the vertical plate under force, causing the round rod to move. At this time, the spring is in a stretched state. While the round rod is moving, it drives the arc-shaped clamping plate to move, so that the arc-shaped anti-slip pad eliminates the limiting effect on the filter cotton cylinder.

[0007] Preferably, an arc-shaped anti-slip pad is fixedly connected to one side of the arc-shaped clamp, and the arc-shaped anti-slip pad is made of rubber.

[0008] The effect achieved by the above components is to increase friction by forming an arc-shaped anti-slip pad.

[0009] Preferably, two limiting rods are fixedly connected to the sides of the two pull plates that are close to each other, and the arc surfaces of the two limiting rods are slidably connected to the vertical plate.

[0010] The effect achieved by the above components is that the movement of the pull plate causes the limiting rod to slide on the vertical plate.

[0011] Preferably, one end of the limiting rod is fixedly connected to a limiting plate, and a limiting ring is fixedly connected to the side of the two vertical plates that are close to each other.

[0012] The effect achieved by the above-mentioned components is to prevent the vertical plate from deforming due to the limiting ring.

[0013] Preferably, the bottom end of the limiting ring is fixedly connected to four support rods, and one end of each of the four support rods is fixedly connected to the fixing ring.

[0014] The aforementioned components achieve the effect of fixing the support rod between the fixed ring and the limiting ring.

[0015] Preferably, the arc surface of the limiting ring is provided with a transmission device, the transmission device includes two fixing blocks, one end of the two fixing blocks is fixedly connected to the limiting ring, and a fixing rod is fixedly connected to the side of the two fixing blocks that are far apart from each other.

[0016] The effect achieved by the above components is that the fixing rod is fixed on the fixing block.

[0017] Preferably, the arc surface of the fixing rod is rotatably connected to a ring.

[0018] The effect achieved by the above components is that the ring and the fixed rod are matched, and the ring rotates on the fixed rod.

[0019] Preferably, a connecting plate is fixedly connected to the arc surface of the ring, and an arc-shaped tie rod is fixedly connected to one side of the two connecting plates that are close to each other.

[0020] The effect achieved by the above components is that the arc-shaped tie rod, under force, drives the connecting plate to rotate around the ring as the center.

[0021] Preferably, the arc-shaped tie rod is externally fixedly connected with an anti-slip sleeve, which is made of rubber.

[0022] The effect achieved by the above components is to increase friction by implementing anti-slip sleeves.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] In this invention, a fixing device is used to install a filter cotton cartridge outside the filter element body when it is necessary to increase the service life of the filter element. The filter cotton cartridge first purifies the air. The fixing device solves the problem that in traditional multi-layer air purifier filter elements, many particulate impurities adhere to the filter element during long-term air purification, which reduces the service life of the filter element and requires replacement with a new filter element, thus increasing the cost of air purification.

[0025] In this invention, through a transmission device, when it is necessary to easily pull the filter element assembly, the anti-slip sleeve is pulled. The anti-slip sleeve is subjected to tension, which is transmitted to the connecting plate. The continuous tension applied to the connecting plate can drive the filter element assembly to move. Through the transmission device, the problem of traditional multi-layer air purifier filter elements being produced in a cylindrical shape and being inconvenient to remove after being placed inside the air purifier is solved.

[0031] Reference Figure 1 and Figure 3 As shown, this utility model provides a technical solution: a multi-layer air purifier filter element assembly, including a filter element body 1 and an activated carbon filter cartridge 4. The filter element body 1 is provided with a fixing device 2 on its exterior, and a transmission device 3 is provided on the arc surface of the limiting ring 210.

[0032] The following section will describe in detail the specific setup and function of its fixing device 2 and transmission device 3.

[0033] Reference Figure 2As shown in this embodiment: the fixing device 2 includes a fixing ring 201 and a filter cotton cylinder 207. The inner side of the fixing ring 201 is fixedly connected to the filter element body 1. Two vertical plates 202 are fixedly connected to the top of the fixing ring 201. Two round rods 203 are slidably connected to one side of the vertical plates 202. A pull plate 212 is fixedly connected to one end of the two round rods 203. A spring 204 is sleeved on the arc surface of the round rod 203. The two ends of the two springs 204 are fixedly connected to the pull plate 212 and the vertical plate 202, respectively. An arc-shaped clamping plate 205 is fixedly connected to one end of the round rod 203. When the pull plate 212 is subjected to force and moves away from the vertical plate 202, the round rod 203 moves. At this time, the spring 204 is in a stretched state. When the round rod 203 moves, it drives the arc-shaped clamping plate 205 to move, so that the arc-shaped anti-slip pad 206 eliminates the limiting effect on the filter cotton cylinder 207. An arc-shaped anti-slip pad 206, made of rubber, is fixedly connected to one side of the arc-shaped clamping plate 205. This increases friction. Two limiting rods 208 are fixedly connected to the sides of the two pull plates 212 that are close to each other. The arc surfaces of the two limiting rods 208 are slidably connected to the vertical plate 202. This allows the pull plates 212 to move, causing the limiting rods 208 to slide on the vertical plate 202. A limiting plate 209 is fixedly connected to one end of each limiting rod 208, and a limiting ring 210 is fixedly connected to the sides of the two vertical plates 202 that are close to each other. This prevents the vertical plate 202 from deforming. Four support rods 211 are fixedly connected to the bottom of the limiting ring 210, with one end of each support rod 211 fixedly connected to the fixed ring 201. This fixes the support rods 211 between the fixed ring 201 and the limiting ring 210.

[0034] Reference Figure 4 As shown in this embodiment: the transmission device 3 includes two fixed blocks 31, one end of which is fixedly connected to the limiting ring 210. A fixed rod 32 is fixedly connected to each of the two fixed blocks 31 on opposite sides. This achieves the effect of fixing the fixed rod 32 to the fixed block 31. A ring 33 is rotatably connected to the arc surface of the fixed rod 32. This achieves the effect of the ring 33 and the fixed rod 32 being compatible, and the ring 33 rotating on the fixed rod 32. A connecting plate 34 is fixedly connected to the arc surface of the ring 33. An arc-shaped pull rod 35 is fixedly connected to the side of the two connecting plates 34 that are close to each other. This achieves the effect of the arc-shaped pull rod 35 being forced to rotate the connecting plate 34 around the ring 33. An anti-slip sleeve 36, made of rubber, is fixedly connected to the outside of the arc-shaped pull rod 35. This achieves the effect of increasing friction.

[0035] Working principle: Using fixing device 2, when it is necessary to extend the service life of the filter element, the operator first pulls the pull plate 212 away from it. The pull plate 212, under tension, moves the round rod 203. At this time, the spring 204 is in a contracted state. The round rod 203 moves the arc-shaped clamping plate 205, which in turn moves the arc-shaped anti-slip pad 206 away from the filter element body 1. When the arc-shaped clamping plate 205 moves to abut against the vertical plate 202, the filter cotton cylinder 207 can be fitted around the filter element body 1. After the filter cotton cylinder 207 is assembled, the pull plate 212 is released, the restrictive force on the pull plate 212 is eliminated, and the spring 204 rebounds, driven by the pull plate 212. The round rod 203 moves, causing the arc-shaped clamp 205 to bring the arc-shaped anti-slip pad 206 and the filter cotton cylinder 207 into contact, so that the filter cotton cylinder 207 and the filter element body 1 are in contact. When the filter element body 1 purifies the air, the air is first purified by the filter cotton cylinder 207. More particulate impurities in the air adhere to the filter cotton cylinder 207, thereby preventing excessive particulate impurities from adhering to the filter element body 1 and the activated carbon filter cylinder 4 after long-term use. Through the fixing device 2, the problem of many particulate impurities adhering to the filter element during long-term air purification in traditional multi-layer air purifier filter elements is solved, which leads to a reduction in the service life of the filter element and the need to replace it with a new filter element, thus increasing the cost of air purification.

[0036] With the transmission device 3, when it is necessary to easily pull the filter element assembly, the operator first pulls the anti-slip sleeve 36. The tension on the anti-slip sleeve 36 is transmitted to the connecting plate 34. The continuous tension applied to the connecting plate 34 can drive the filter element assembly to move. Through the transmission device 3, the problem of traditional multi-layer air purifier filter elements being produced in a cylindrical shape and being inconvenient to remove after being placed inside the air purifier is solved.
