Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, specifically to a filter structure for spray-coated air purification equipment that is easy to install and clean. Background Technology

[0002] Paint is a chemical mixture that can firmly cover the surface of an object, serving as a protector, decorator, marker, and for other special purposes. During the paint spraying process, a large amount of waste gas is often generated. To ensure a clean and safe environment, air purification equipment is usually used to filter this waste gas.

[0003] Currently, most air purifier filters are installed inside the purifier housing. Therefore, cleaning the internal filter requires removing the housing first and then removing the filter. Since the housing is usually fixed with bolts, the disassembly and assembly process is cumbersome and inconvenient for cleaning the inside. To address this, we propose a spray-coated filter structure for air purification equipment that is easy to install and clean. Utility Model Content

[0004] The purpose of this invention is to provide a filter structure for spray-coated air purification equipment that is easy to install and clean, in order to solve the problem mentioned in the background art that the filter screen of the current air purifier is cumbersome to disassemble and clean.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter structure for a spray-painted air purification device that is easy to install and clean, comprising an air purifier body, a cover plate, and a connecting mechanism. The cover plate is connected to the front side of the air purifier body via the connecting mechanism. An installation cavity is formed on the front side of the air purifier body, and an embedded groove is formed in the middle of the rear side of the installation cavity. A filter screen is disposed inside the embedded groove. The connecting mechanism includes a fixing plate, a bearing, a rotating cylinder, a compression spring, a stop plate, an L-shaped groove, a connecting plate, a pressing column, and a clamp. The air purifier body has a fixed plate fixedly connected to the front center of the left and right sides. A bearing is fixedly connected through the front center of the fixed plate. A rotating cylinder is fixedly connected to the inner ring side wall of the bearing. A compression spring is fixedly connected to the rear center of the inner cavity of the rotating cylinder. A stop plate is fixedly connected to the front end of the compression spring. An L-shaped groove is symmetrically opened through the front of the outer side wall of the rotating cylinder. A connecting plate is symmetrically fixedly connected to the front of the cover plate. A pressing column is fixedly connected to the rear of the connecting plate. A locking block is symmetrically fixedly connected to the rear of the outer side wall of the pressing column.

[0006] As a further description of the above technical solution:

[0007] The abutment is slidably connected to the inside of the rotating cylinder, and the outer side wall of the abutment is in contact with the inner side wall of the rotating cylinder.

[0008] As a further description of the above technical solution:

[0009] The length, width, and height of the cover plate are equal to the length, width, and height of the mounting cavity.

[0010] As a further description of the above technical solution:

[0011] The length, width, and height of the filter screen are equal to the length, width, and height of the embedded groove.

[0012] As a further description of the above technical solution:

[0013] A limiting mechanism is provided on the outer side of the rotating cylinder. The limiting mechanism includes a rotating disk, a slot, a mounting plate, a pull rod, a limiting block, and a connecting spring. The rotating disk is fixedly connected to the rear of the outer side wall of the rotating cylinder. The outer side wall of the rotating disk has a slot. The mounting plate is fixedly connected to the middle of the top front side of the fixed plate. The top center of the mounting plate is slidably connected to the pull rod. The bottom end of the pull rod is fixedly connected to the limiting block. A connecting spring is sleeved on the outer side of the pull rod.

[0014] As a further description of the above technical solution:

[0015] The upper and lower ends of the connecting spring are fixedly connected to the bottom of the mounting plate and the top of the limiting block, respectively.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The filter structure of this easy-to-install and clean spray air purification equipment allows for easy cleaning. When cleaning is required, the limiting mechanism releases the fixing of the rotating cylinder, and the rotating cylinder is rotated, causing the locking block to deflect inside the L-shaped groove. When the locking block rotates to the vertical part of the L-shaped groove, the compression spring resets, causing the abutment plate to push the extrusion column out of the rotating cylinder, releasing the fixing of the cover plate, and allowing the filter screen to be disassembled. This avoids the use of bolts for connection, making it convenient to disassemble and clean the filter screen, saving disassembly and assembly time, and improving the convenience of the device.

[0018] 2. This easy-to-install and clean spray air purification equipment uses a filter structure. Pulling the pull rod causes the limit block to rise, compressing the connecting spring. After the cover plate is installed, the slot is aligned with the limit block. Loosening the pull rod and resetting the connecting spring resets the limit block, causing it to be embedded in the slot and fixing the rotating disc, thereby fixing the rotating cylinder and preventing the connection mechanism from loosening, ensuring the stability of the connection and preventing loosening.

[0028] This utility model provides a filter structure for spray-painted air purification equipment that is easy to install and clean. It avoids the use of bolts for connection, facilitates filter screen disassembly and cleaning, saves assembly and disassembly time, and improves the convenience of the device. Please refer to [link / reference]. Figure 1-5 It includes an air purifier body 100, a cover plate 200, and a connecting mechanism 300;

[0029] Please refer to it again. Figure 1 The air purifier body 100 is used to install the cover plate 200 and the connecting mechanism 300;

[0030] Please refer to it again. Figure 1-3 The cover plate 200 is connected to the front side of the air purifier body 100 through the connecting mechanism 300. The front side of the air purifier body 100 is provided with an installation cavity 110, and the rear middle of the installation cavity 110 is provided with an embedded groove 120. A filter screen 130 is provided inside the embedded groove 120.

[0031] Please refer to it again. Figure 4 The connecting mechanism 300 includes a fixed plate 310, a bearing 320, a rotating cylinder 330, a compression spring 340, a stop plate 350, an L-shaped groove 360, a connecting plate 370, a pressing column 380, and a locking block 390.

[0032] Please refer to it again. Figure 4 A fixing plate 310 is fixedly connected to the front middle part of the left and right sides of the air purifier body 100. A bearing 320 is fixedly connected through the front middle part of the fixing plate 310. A rotating cylinder 330 is fixedly connected to the inner ring side wall of the bearing 320. A compression spring 340 is fixedly connected to the rear middle part of the inner cavity of the rotating cylinder 330.

[0033] Please refer to it again. Figure 4 The front end of the compression spring 340 is fixedly connected to the abutment plate 350. The outer side wall of the rotating cylinder 330 is symmetrically provided with an L-shaped groove 360. The front side of the cover plate 200 is symmetrically fixedly connected to the connecting plate 370. The rear side of the connecting plate 370 is fixedly connected to the extrusion column 380. The rear side of the outer side wall of the extrusion column 380 is symmetrically fixedly connected to the locking block 390.

[0034] In summary, when cleaning is required, the limiting mechanism 400 releases the fixing of the rotating cylinder 330, and the rotating cylinder 330 is rotated, causing the locking block 390 to deflect inside the L-shaped groove 360. The locking block 390 rotates to the vertical part of the L-shaped groove 360, and the compression spring 340 resets, causing the abutment plate 350 to push the squeezing column 380 out of the rotating cylinder 330, releasing the fixing of the cover plate 200, and disassembling the filter screen 130. This avoids the use of bolts for connection, making it convenient to disassemble the filter screen 130 for cleaning, saving disassembly and assembly time, and improving the convenience of the device.

[0035] Please refer to it again. Figure 4 The abutment plate 350 is slidably connected to the inside of the rotating cylinder 330, and the outer side wall of the abutment plate 350 is in contact with the inner side wall of the rotating cylinder 330.

[0036] Please refer to it again. Figure 1 The length, width, and height of the cover plate 200 are equal to the length, width, and height of the mounting cavity 110.

[0037] Please refer to it again. Figure 3 The length, width, and height of the filter screen 130 are equal to the length, width, and height of the embedded groove 120.

[0038] Please refer to it again. Figure 5 A limiting mechanism 400 is provided on the outer side of the rotating cylinder 330. The limiting mechanism 400 includes a rotating disk 410, a slot 420, a mounting plate 430, a pull rod 440, a limiting block 450, and a connecting spring 460. The rotating disk 410 is fixedly connected to the rear part of the outer side wall of the rotating cylinder 330. The slot 420 is opened on the outer side wall of the rotating disk 410. The mounting plate 430 is fixedly connected to the middle part of the top front side of the fixed plate 310. The pull rod 440 is slidably connected through the top middle part of the mounting plate 430. The limiting block 450 is fixedly connected to the bottom end of the pull rod 440. The connecting spring 460 is sleeved on the outer side of the pull rod 440.

[0039] Please refer to it again. Figure 5 The upper and lower ends of the connecting spring 460 are fixedly connected to the bottom of the mounting plate 430 and the top of the limiting block 450, respectively.

[0040] In summary, pulling the lever 440 causes the limiting block 450 to rise, compressing the connecting spring 460. After the cover plate 200 is installed, the slot 420 aligns with the limiting block 450. Loosening the lever 440 allows the connecting spring 460 to reset the limiting block 450, causing it to embed itself in the slot 420 and fix the rotating disk 410, thereby fixing the rotating cylinder 330. This prevents the connecting mechanism 300 from loosening, ensuring the stability of the connection and preventing it from becoming loose.

[0041] In practical use, when those skilled in the art need to clean the filter screen 130, they pull the lever 440, causing the limiting block 450 to rise, releasing the fixation on the rotating disk 410, thereby releasing the fixation on the rotating cylinder 330. Rotating the rotating cylinder 330 causes the locking block 390 to deflect inside the L-shaped groove 360, rotating it to the vertical part of the L-shaped groove 360. Through the reset of the compression spring 340, the abutment plate 350 pushes the extrusion column 380 out of the rotating cylinder 330, releasing the fixation on the cover plate 200. The filter screen 130 can then be disassembled and cleaned. After cleaning, the lever 440 is pulled again, causing the limiting block 450 to rise, compressing the connecting spring 460, and installing the filter screen 130 into the inner groove 120. Then, the locking block 390 is removed. Aligning with the vertical portion of the L-shaped groove 360, the extrusion column 380 is positioned within the rotating cylinder 330, thereby embedding the locking block 390 within the L-shaped groove 360. Simultaneously, the extrusion column 380 extrudes the abutment plate 350, compressing the compression spring 340. When the locking block 390 is positioned at the rear of the L-shaped groove 360, the rotating cylinder 330 is rotated, positioning the locking block 390 at the end of the L-shaped groove 360, thus limiting the locking block 390 and allowing the cover plate 200 to be installed in the mounting cavity 110. After the cover plate 200 is installed, the locking groove 420 is aligned with the limiting block 450. The pull rod 440 is loosened, and the limiting block 450 is reset by the reset of the connecting spring 460, embedding the limiting block 450 within the locking groove 420 and fixing the rotating disk 410, thereby fixing the rotating cylinder 330.
