Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to a dustproof and heat dissipation integrated fan circuit board. Background Technology

[0002] An electric fan, also known as a fan or air ventilator, is a household appliance that uses an electric motor to drive fan blades to rotate and accelerate air circulation. Its core functions include cooling and air circulation. It consists of an AC motor, a fan blade assembly, and a gearbox. Its working principle is based on the rotation of a current-carrying coil in a magnetic field. Household electric fans are essentially axial flow fans, meaning the airflow is parallel to the fan blade's rotation axis. They can be classified by power supply voltage (DC brushless fans and AC fans) and by bearing type (ball bearing fans and oil bearing fans). A circuit board is installed inside the fan casing to arrange and control the fan's electrical circuitry.

[0003] However, in the existing technology, during the production of fans, in order to prevent the circuit board from aging and being damaged by a large amount of dust and impurities, the circuit board is sealed and protected. However, as the fan is used for a long time, some electrical components inside will heat up, and the sealed circuit board has no outlet to dissipate the heat, which makes the circuit board operate in a high-temperature environment, which is prone to damage. Utility Model Content

[0004] The purpose of this utility model is to provide a dustproof and heat dissipation integrated fan circuit board, which has the advantages of sealing and protecting the circuit board to prevent dust from entering and damaging the circuit board, and allowing the circuit board's working environment to be ventilated to prevent operation in high-temperature environments, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof and heat dissipation integrated fan circuit board, comprising a placement component, a sealing component, and two ventilation components. The placement component is used to install and place the electrical components of the fan. The sealing component is disposed on the placement component to surround the fan electrical components and provide dustproof and ventilation protection. The other two ventilation components are disposed on the sealing component to surround the fan electrical components, provide dustproof and ventilation protection, and seal the wiring. The sealing component includes a mounting cover, a U-shaped plate, a filter screen, and four fixing components. The mounting cover is disposed on the placement component. The U-shaped plate is fixedly mounted on the mounting cover by fasteners. The filter screen is fixedly mounted inside the U-shaped plate. All four fixing components are disposed inside the mounting cover.

[0006] Furthermore, the fixing component includes a retaining plate and two spring plates. The retaining plate is fixedly installed on the top inner wall of the mounting cover, and both spring plates are disposed on the placement component.

[0007] Furthermore, each of the two outer walls of the card plate is provided with a triangular protrusion one, and each of the outer walls of the two spring plates that are close to each other is provided with a triangular protrusion two, and the triangular protrusion one and the triangular protrusion two are connected to each other.

[0008] Furthermore, the placement assembly includes a base plate, a placement frame, and a circuit board. The placement frame is fixedly installed on the top of the base plate, the circuit board is fixedly installed inside the placement frame by fasteners, and the spring plate is fixedly connected to the base plate.

[0009] Furthermore, a limiting plate is fixedly installed on the top of the base plate, and the limiting plate is adapted to the mounting cover.

[0010] Furthermore, the breathable component includes three fixed frames, three filter screens, two rings, and valves. The three fixed frames are all fixedly installed on the mounting cover, the three filter screens are respectively fixedly installed inside the fixed frames, the two rings are all fixedly installed on the mounting cover, and the valves are evenly distributed inside the two rings.

[0011] Furthermore, the valve is made of rubber and is shaped like a quarter circle.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are: This invention utilizes a closed assembly to remove the base plate and circuit board. The circuit board is then moved and aligned with the placement frame. It is then positioned within the placement frame and secured to the base plate with fasteners. Next, the mounting cover is lifted and positioned on the base plate. Moving the mounting cover moves the clamping plate, which then engages with the spring plate. The clamping plate compresses the spring plate, causing it to deform and bend away from each other. When the gap between the spring plates aligns with the clamping plate, the clamping plate enters the gap, releasing its elasticity and resetting, hooking back into place with the clamping plate to secure the mounting cover. A U-shaped plate and a filter screen work together to create an opening above the circuit board, allowing ventilation through the U-shaped plate and filtering dust through the filter screen to prevent contamination. This design provides enclosed protection for the circuit board, preventing dust from entering and damaging it, while also allowing ventilation to the working environment and preventing damage during high-temperature operation.

[0013] This invention, by setting up a breathable component, allows for the soldering of wires to the circuit board before placing the mounting cover. One end of the wire is picked up and inserted into the corresponding ring. After entering the ring, it contacts the valve. As the wire continues to move, the valve is pushed and flipped outwards. Simultaneously, the gap between the wire and the ring is filled, preventing dust from entering the mounting cover through the gap. The fixed frame and the second filter work together to create an opening on the side of the circuit board. The fixed frame allows for side heat dissipation and ventilation, while the second filter filters out dust and impurities, preventing dust from contaminating the circuit board. This invention has the advantages of arranging connecting wires and preventing dust and impurities from entering through the gaps in the wire arrangement and contaminating or damaging the circuit board.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] This utility model provides, for example Figures 1-4 As shown, a dustproof and heat-dissipating integrated fan circuit board includes a placement component 1, a sealing component 2, and two ventilation components 3. The placement component 1 is used to install and place the electrical components of the fan. The sealing component 2 is disposed on the placement component 1 to surround the fan electrical components and provide dustproof and ventilation protection. The other two ventilation components 3 are disposed on the sealing component 2 to surround the fan electrical components, provide dustproof and ventilation protection, and seal the wiring. The sealing component 2 includes a mounting cover 201, a U-shaped plate 202, a filter 203, and four fixing components. The mounting cover 201 is disposed on the placement component 1. The U-shaped plate 202 is fixedly mounted on the mounting cover 201 by fasteners. The filter 203 is fixedly mounted inside the U-shaped plate 202. All four fixing components are disposed inside the mounting cover 201. More specifically, the base plate 101 and the circuit board 103 are removed, the circuit board 103 is moved, the circuit board 103 is aligned with the placement frame 102, the circuit board 103 is moved and placed inside the placement frame 102 for positioning, and then fixed by fasteners. The circuit board 103 is fixed on the base plate 101. The mounting cover 201 is then lifted and positioned on the base plate 101. The mounting cover 201 moves, causing the clamping plate 204 to move as well. The clamping plate 204, as the mounting cover 201 moves, comes into contact with the spring plate 205. The movement of the clamping plate 204 compresses the spring plate 205, causing it to deform and bend away from each other. When the gap between the spring plates 205 is flush with the clamping plate 204, the clamping plate 204 enters the space between the spring plates 205. Within the spacing, the spring plate 205 releases its elastic force to reset and hooks with the clamping plate 204, limiting the mounting cover 201. The U-shaped plate 202 and the filter screen 203 cooperate to open the top of the circuit board 103, allowing ventilation through the U-shaped plate 202 and filtering dust through the filter screen 203 to prevent dust from contaminating the circuit board 103. This has the advantages of sealing and protecting the circuit board 103, preventing dust from entering and damaging the circuit board 103, and allowing ventilation of the working environment of the circuit board 103 to prevent operation in high-temperature environments.

[0018] In addition, the fixing component includes a clamping plate 204 and two spring plates 205. The clamping plate 204 is fixedly installed on the top inner wall of the mounting cover 201, and the two spring plates 205 are both disposed on the placement component 1.

[0019] In addition, triangular protrusions are provided on both outer walls of the card plate 204, and triangular protrusions are provided on the outer walls of the two spring plates 205 that are close to each other. The triangular protrusions are connected to each other.

[0020] like Figure 1As shown, in some embodiments, the placement assembly 1 includes a base plate 101, a placement frame 102, and a circuit board 103. The placement frame 102 is fixedly installed on the top of the base plate 101, and the circuit board 103 is fixedly installed inside the placement frame 102 by fasteners. The spring plate 205 is fixedly connected to the base plate 101.

[0021] In some embodiments, a limiting plate is fixedly installed on the top of the base plate 101, and the limiting plate is adapted to the mounting cover 201.

[0022] like Figure 1 As shown, in some embodiments, the breathable component 3 includes three fixed frames 301, three filter screens 302, two rings 303, and valves 304. The three fixed frames 301 are all fixedly mounted on the mounting cover 201, the three filter screens 302 are respectively fixedly mounted inside the fixed frames 301, the two rings 303 are all fixedly mounted on the mounting cover 201, and the valves 304 are evenly distributed within the two rings 303. More specifically, before placing the mounting cover 201, the wires are soldered to the circuit board 103, one end of the wire is picked up and inserted into the corresponding ring 303. The inner part contacts the valve 304. As the wire continues to move, the valve 304 is pushed and flipped outward with the movement of the wire. At the same time, the gap between the wire and the ring 303 is filled, preventing dust from entering the mounting cover 201 through the gap. The fixing frame 301 and the second filter 302 cooperate to open the side of the circuit board 103. The fixing frame 301 allows for side heat dissipation and ventilation, while the second filter 302 filters dust and impurities, preventing dust from contaminating the circuit board 103. This has the advantages of arranging the connecting wires and preventing dust and impurities from entering through the gaps in the wire arrangement and contaminating or damaging the circuit board 103.

[0023] In some embodiments, the valve 304 is made of rubber and is arranged in a quarter-circle shape.

[0024] Working principle: Step 1: Placement and docking. Take out the base plate 101 and circuit board 103. Move the circuit board 103 until it aligns with the placement frame 102. Place the circuit board 103 within the placement frame 102 for positioning. Then, fix the circuit board 103 to the base plate 101 using fasteners. At this point, pick up the mounting cover 201 and place its opening on the base plate 101. Move the mounting cover 201, which in turn moves the clamping plate 204. As the mounting cover 201 moves, the clamping plate 204 engages with the spring plate 205. The movement of the clamping plate 204 also engages with the spring plate 205. The spring plates 205 are compressed, causing them to deform and bend away from each other. When the gap between the spring plates 205 is flush with the clamping plate 204, the clamping plate 204 enters the gap between the spring plates 205. The spring plates 205 release their elasticity, reset, and hook with the clamping plate 204, limiting the mounting cover 201. The U-shaped plate 202 and the filter screen 203 cooperate to open the top of the circuit board 103, allowing air to pass through the U-shaped plate 202 and filtering dust through the filter screen 203 to prevent dust from contaminating the circuit board 103.

[0025] Step 2: Ventilation cable routing. Before placing the mounting cover 201, solder the wire to the circuit board 103. Pick up one end of the wire and insert it into the corresponding ring 303. After entering the ring 303, it contacts the valve 304. The wire continues to move, causing the valve 304 to be pushed and flipped outward as the wire moves. At the same time, the gap between the wire and the ring 303 is filled, preventing dust from entering the mounting cover 201 through the gap. The fixing frame 301 and the second filter 302 cooperate to open the side of the circuit board 103. The fixing frame 301 provides side heat dissipation and ventilation, and the second filter 302 filters dust and impurities to prevent dust from contaminating the circuit board 103.
