Description

Technical Field

[0001] This utility model belongs to the field of air purifier technology, and in particular relates to an air purifier circuit board mounting structure. Background Technology

[0002] Air purifiers primarily remove air pollutants such as particulate matter, formaldehyde, bacteria, and viruses through technologies like filtration, adsorption, and decomposition. The circuit board is the core hardware component of an air purifier, mainly responsible for controlling and coordinating the various functional components. The circuit board converts the input AC power into DC power suitable for the internal components of the air purifier and manages the power distribution and usage to ensure the normal operation of each component.

[0003] However, the above-mentioned device still has the following problems in the implementation process: The most common method in the existing technology is to fix it with screws. By drilling screw holes in the circuit board in advance, the circuit board is fixed in the air purifier housing with screws. This method requires the installation of multiple screws with a screwdriver, which is time-consuming. Moreover, the frequent removal and removal of screws will cause damage to the housing. Therefore, an air purifier circuit board mounting structure is proposed to solve the above problems. Utility Model Content

The bottom of the purification device is fixedly connected to the support plate by screws. The mounting groove is located at the bottom of the purification device, and the top of the connecting frame is fixedly connected to the interior of the mounting groove.

[0005] The inner cavity of the connecting frame is movably connected to a circuit board. The bottom of the connecting frame has two mating holes. Connecting holes are also provided on the left and right sides of the bottom of the connecting frame. A cylindrical block is fixedly connected to the inner cavity of the connecting hole. Movable holes are also provided on the left and right sides of the connecting frame. A receiving groove is provided in the inner cavity of the cylindrical block.

[0007] As a preferred embodiment of this utility model, a matching plate is fixedly connected to the top of the inner cavity of the mounting groove, and a matching groove for use with the circuit board is opened at the bottom of the matching plate. The circuit board is movably connected to the inner cavity of the matching groove. By setting the matching plate and the matching groove, after the circuit board is docked with the matching plate, the matching groove can position the circuit board, so that the circuit board can quickly dock with the limiting rod.

[0008] In a preferred embodiment of this invention, a flip plate is movably connected to the inner cavity of the movable hole. A first tooth is fixedly connected to the surface of the flip plate, and there are multiple first teeth. A U-shaped plate is movably connected to the inner cavity of the mounting groove.

By setting the flip plate, the first tooth, the U-shaped plate, and the second tooth, the movement of the U-shaped plate will cause the first tooth and the second tooth to mesh. At this time, the position of the two flip plates can be controlled.

[0009] As a preferred embodiment of this utility model, a fixed plate is movably connected to the bottom of the flip plate. The fixed plate is fixedly connected to the connecting frame on the side near the connecting frame. A positioning hole is provided at the bottom of the fixed plate. A positioning plate is movably connected to the inner cavity of the positioning hole. The top of the positioning plate is fixedly connected to the flip plate.

By setting the positioning component, after the flipping plate contacts the circuit board, the pressure of the torsion spring on the torsion plate can position the flipping plate, thus enabling the flipping plate to position the circuit board.

[0011] As a preferred embodiment of this utility model, a travel hole is provided on the rear side of the U-shaped plate, and a travel rod is movably connected to the inner cavity of the travel hole. The rear side of the travel rod is fixedly connected to the inner wall of the mounting groove. Insertion holes are provided on the front and rear sides of the right side of the travel rod. By setting the travel hole, the travel rod, and the insertion holes, the travel rod and the travel hole can control the movement position of the U-shaped plate when it moves, so that the U-shaped plate will not cause the first tooth to disengage from the second tooth.

[0012] In a preferred embodiment of this invention, a movable groove is provided on the right side of the travel hole, and a movable block is movably connected to the inner cavity of the movable groove. A plug-in block for use with a plug-in hole is fixedly connected to the left side of the movable block. The plug-in block is plugged into the inner cavity of the plug-in hole. A moving hole is provided at the bottom of the movable groove, and the bottom of the movable block passes through the moving hole and extends to the outside of the U-shaped plate.

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

[0014] This invention utilizes a combination of movable holes, receiving grooves, limiting rods, and positioning components. When the circuit board is picked up and aligned with the matching groove at the bottom of the matching plate, the connecting rod passes through the circuit board, and then the U-shaped plate can be pushed back to its original position. At this time, the torsion spring undergoes elastic deformation, causing the flip plate to position the circuit board. This solves the problem that the installation process with multiple screws is time-consuming, and that frequent screw removal can damage the casing. Attached Figure Description

[0037] The working principle of this utility model:

[0038] In use, first remove the support plate 2 from the purification equipment 1 using a bolt cutter. Then, pull the movable block 26 to compress the spring 29 in the movable groove 25. When the movable block 26 drives the plug block 27 to disengage from the plug hole 24, push the U-shaped plate 17 to engage the second tooth 18 with the first tooth 16. At this time, the flip plate 15 will rotate. The rotation of the flip plate 15 will cause the positioning plate 21 to rotate in the positioning hole 20, and it will also cause the rotating rod 121 to rotate. The rotation of the rotating rod 121 will cause the torsion plate 12 to rotate. 2. Twist the torsion spring 123. When the flip plate 15 is rotated to the appropriate position, pick up the circuit board 5 and connect it with the matching groove 14 at the bottom of the matching plate 13. At this time, the plug rod will pass through the circuit board 5. Then, push the U-shaped plate 17 back to its original position.

The spring 29 will undergo elastic deformation to drive the plug block 27 to be inserted into the plug hole 24. At this time, the position of the U-shaped plate 17 can be fixed.

[0039] In summary, the air purifier circuit board 5 mounting structure, through the coordinated use of the movable hole 9, receiving groove 10, limiting rod 11, and positioning component 12, allows the circuit board 5 to be picked up and aligned with the matching groove 14 at the bottom of the matching plate 13. At this time, the connecting rod will pass through the circuit board 5, and then the U-shaped plate 17 can be pushed back to its original position. Then, the torsion spring 123 will undergo elastic deformation, causing the flip plate 15 to position the circuit board 5. This solves the problem that the installation process with multiple screws is time-consuming, and the frequent removal of screws will cause damage to the casing.
