[0002] As people's living standards continue to improve, their requirements for indoor environments are also increasing. In order to improve the indoor air environment, air purifiers are usually used indoors.

[0003] Existing air purifiers are equipped with negative ion generators. The working principle of a negative ion generator is to create an electric field in the space between the negative ion emitter and the negative ion ground wire. The air is ionized by the discharge at the tip of the negative ion emitter, thereby generating negative ions. The generated negative ions have the function of removing dust and purifying the air.

[0004] However, in the process of dust removal and air purification, dust in the air will adhere to the tip of the emitting end (carbon brush) of the negative ion generator and the receiving end (carbon brush) of the negative ion ground wire. If it is not cleaned in time, it will affect the efficiency of the negative ion generator in generating negative ions. Therefore, this application proposes a cleaning mechanism for negative ion generators. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figure 1-8 This utility model provides a technical solution: a negative ion generator cleaning mechanism, including a middle shell 1, which is a disc-shaped structure, and grooves are provided on both the upper and lower surfaces of the middle shell 1. An upper shell 2 is provided at the edge of the upper surface of the middle shell 1. A humidifier 5 is provided inside the upper shell 2. The humidifier 5 is a commercially available humidifier, which will not be described in detail in this application. A humidification hole is provided at the center of the top of the upper shell 2, and the atomizing nozzle of the humidifier 5 corresponds to the humidification hole. The humidifier 5 is controlled to work independently by a PLC control board 8. The humidifier 5 atomizes and sprays clean water, and then sprays the atomized clean water into the indoor air through the humidification hole at the top of the upper shell 2, thereby humidifying the indoor air.

[0030] The middle shell 1 has a negative ion output hole 10 on one side of its edge. A T-shaped branch pipe 17 is rotatably installed on the upper surface of the middle shell 1 at the position corresponding to the negative ion output hole 10. The two ends of the horizontal tube of the T-shaped branch pipe 17 are rotatably installed on the middle shell 1. A negative ion emitter 11 corresponding to the negative ion output hole 10 is provided in one of the pipe openings at the free end of the T-shaped branch pipe 17. A duct cover plate 7 covering the T-shaped branch pipe 17 is provided on the upper surface of the middle shell 1. A cleaning groove 18 is provided on the lower surface of the duct cover plate 7 at the position corresponding to the negative ion emitter 11. Before the negative ion generator 6 is working, the negative ion emitter 11 is driven by the T-shaped branch pipe 17 to rotate into the cleaning groove 18. At the same time, the emitter tip (carbon brush) at the end of the negative ion emitter 11 contacts the inner wall of the cleaning groove 18, and the dust adhering to the emitter tip (carbon brush) at the end of the negative ion emitter 11 is scraped off by the inner wall of the cleaning groove 18.

[0031] The middle shell 1 has a bottom cover 4 below it. A lower shell 3 is located between the lower surface of the middle shell 1 and the upper surface of the bottom cover 4. A fixing frame 13 is located on the upper surface of the bottom cover 4. A fan-shaped groove 21 is located on one side of the lower surface of the fixing frame 13. A negative ion ground wire 14 is located on the fixing frame 13. The end of the negative ion ground wire 14 extends into the fan-shaped groove 21. A brush plate 22 that cooperates with the carbon brush at the end of the negative ion ground wire 14 is rotatably installed in the fan-shaped groove 21. Before the negative ion generator 6 works, the brush plate 22 in the fan-shaped groove 21 rotates. Then, the rotating brush plate 22 scrapes off the dust adhering to the receiving end (carbon brush) at the end of the negative ion ground wire 14, thus preventing dust from adhering to the tip (carbon brush) of the emitting end of the negative ion emitter 11 and the receiving end (carbon brush) at the end of the negative ion ground wire 14, thereby improving the efficiency of the negative ion generator 6 in generating negative ions.

[0032] The inner wall of the cleaning groove 18 is bonded with a silicone layer, which will not damage the tip of the negative ion emitter 11 (carbon brush) when the cleaning groove 18 comes into contact with it; the brush plate 22 is made of silicone, which will not damage the receiving end (carbon brush) of the negative ion ground wire 14 when the brush plate 22 comes into contact with it.

[0033] Among them, a first micro motor 16 is provided on the upper surface of the middle shell 1 near the T-shaped branch pipe 17. The output end of the first micro motor 16 is fixedly connected to one end of the horizontal tube of the T-shaped branch pipe 17. Before the negative ion generator 6 works, the first micro motor 16 is controlled to work by the PLC control board 8. Then the first micro motor 16 drives the T-shaped branch pipe 17 to rotate counterclockwise. Then the T-shaped branch pipe 17 drives the negative ion emitter head 11 to rotate counterclockwise, so that the negative ion emitter head 11 rotates into the cleaning groove 18. At the same time, the emitter tip (carbon brush) of the negative ion emitter head 11 contacts the inner wall of the cleaning groove 18. The dust adhering to the tip (carbon brush) of the negative ion emitter head 11 is scraped off by the inner wall of the cleaning groove 18. After the tip (carbon brush) of the negative ion emitter head 11 contacts the inner wall of the cleaning groove 18, the first micro motor 16 drives the T-shaped branch pipe 17 to rotate clockwise. At the same time, the T-shaped branch pipe 17 drives the negative ion emitter head 11 to rotate clockwise, so that the negative ion emitter head 11 rotates out of the cleaning groove 18. Then the negative ion emitter head 11 is aligned with the negative ion output hole 10, which facilitates the subsequent discharge of the tip of the negative ion emitter head 11 to ionize the air and generate negative ions.

[0034] Among them, a second micro motor 19 is provided on one side of the lower surface of the middle shell 1. The output end of the second micro motor 19 is provided with a rotating shaft 20. The end of the rotating shaft 20 is fixedly connected to the rotating shaft of the brush plate 22. The second micro motor 19 can drive the brush plate 22 to reciprocate in the fan-shaped groove 21. During the reciprocating rotation of the brush plate 22, the dust adhering to the receiving end (carbon brush) of the negative ion ground wire 14 can be scraped off.

[0035] Specifically, before the negative ion generator 6 starts working, the second micro motor 19 drives the brush plate 22 to rotate back and forth in the fan-shaped groove 21. During the reciprocating rotation, the surface of the brush plate 22 just contacts the receiving end (carbon brush) at the end of the negative ion ground wire 14. Then, the rotating brush plate 22 scrapes off the dust adhering to the receiving end (carbon brush) at the end of the negative ion ground wire 14, avoiding dust adhering to the tip of the emitter (carbon brush) at the end of the negative ion emitter head 11 and the receiving end (carbon brush) at the end of the negative ion ground wire 14, thus improving the efficiency of the negative ion generator 6 in generating negative ions.

[0036] The upper surface of the middle shell 1 is provided with a negative ion generator 6. The negative ion generator 6 is electrically connected to the negative ion emitter 11 through a wire, and the negative ion generator 6 is electrically connected to the negative ion ground wire 14 through a wire. The negative ion generator 6 is controlled by the PLC control board 8 to form an electric field in the space between the negative ion emitter 11 and the negative ion ground wire 14. The air is ionized by the discharge at the tip of the emitter of the negative ion emitter 11, thereby generating negative ions. These negative ions are emitted into the air through the negative ion emitter 11 to purify the air and replenish the air with negative ions.

[0037] The working principle of the negative ion generator 6 is as follows: The negative ion generator 6 is a device that generates negative air ions. The device processes the input DC or AC power through an EMI processing circuit and a lightning protection circuit, and then raises it to AC high voltage through a pulse circuit, overvoltage current limiting, and high and low voltage isolation circuit. After rectification and filtering by special grade electronic materials, a pure DC negative high voltage is obtained. The DC negative high voltage is connected to the release tip (the emitter tip of the negative ion emitter 11) made of metal or carbon. The DC high voltage at the tip (the emitter tip of the negative ion emitter 11) generates a high corona discharge, which releases a large number of electrons (e-) at high speed. Since electrons cannot exist in the air for long (the lifespan of existing electrons is only on the order of nanoseconds), they are immediately captured by oxygen molecules (O2) in the air, thereby generating negative air ions.

[0038] The duct cover 7 is equipped with a fan 9 inside, and the output end of the fan 9 corresponds to the negative ion emitter 11. An air duct is formed below the duct cover 7 to blow air towards the negative ion output hole 10. The fan 9 is controlled by the PLC control board 8. When the negative ion emitter 11 of the negative ion generator 6 generates air negative ions at the negative ion output hole 10, the fan 9 works at the same time. Then the fan 9 blows air towards the negative ion output hole 10, thereby dispersing the air negative ions around the negative ion output hole 10 and increasing the space for negative ion air purification.

[0039] An air inlet is provided on one side of the edge of the middle shell 1. Outside air is connected to the air duct through the air inlet. When the fan 9 is working, outside air enters the upper surface of the middle shell 1 through the air inlet and is then blown along the air duct to the negative ion output port 10.

[0040] Among them, a hollow groove 12 corresponding to the fan-shaped groove 21 is opened on one side of the lower surface of the bottom cover 4. The hollow groove 12 ensures that the fan-shaped groove 21 is connected to the bottom of the bottom cover 4, and ensures that the receiving end (carbon brush) of the negative ion ground wire 14 in the fan-shaped groove 21 can contact the air at the bottom.

[0041] The upper surface of the mounting bracket 13 is evenly provided with counterweights 23 around the central axis, and the upper surface of the bottom cover 4 is provided with a bottom shell 15 covering the mounting bracket 13 and the counterweights 23, thereby increasing the weight of the bottom cover 4. This lowers the center of gravity of the purifier when it is placed in a horizontal position indoors, preventing the purifier from tipping over.

[0042] Among them, a PLC control board 8 is provided on one side of the upper surface of the middle shell 1. The PLC control board 8 is electrically connected to the humidifier 5, the negative ion generator 6, the fan 9, the first micro motor 16 and the second micro motor 19 respectively. The PLC control board 8 controls the operation of the humidifier 5, the negative ion generator 6, the fan 9, the first micro motor 16 and the second micro motor 19 respectively.

[0043] Working principle: When in use, the humidifier 5 and the negative ion generator 6 are combined. The humidifier 5 humidifies the indoor air and forms an electric field in the space between the negative ion emitter 11 and the negative ion ground wire 14. The air is ionized by the discharge at the tip of the negative ion emitter 11, thereby generating negative ions. These negative ions are emitted into the air through the negative ion emitter 11, thus purifying the air and replenishing it with negative ions.

[0044] Before the negative ion generator 6 operates, the PLC control board 8 controls the first micro motor 16 to operate. Then, the first micro motor 16 drives the T-shaped branch pipe 17 to rotate counterclockwise. The T-shaped branch pipe 17 then drives the negative ion emitter head 11 to rotate counterclockwise, causing the negative ion emitter head 11 to rotate into the cleaning groove 18. At the same time, the emitter tip (carbon brush) at the end of the negative ion emitter head 11 contacts the inner wall of the cleaning groove 18. The emitter tip (carbon brush) at the end of the negative ion emitter head 11 is cleaned by the inner wall of the cleaning groove 18. The dust adhering to the surface is scraped off; after the tip (carbon brush) of the negative ion emitter 11 contacts the inner wall of the cleaning groove 18, the first micro motor 16 drives the T-shaped branch pipe 17 to rotate clockwise. At the same time, the T-shaped branch pipe 17 drives the negative ion emitter 11 to rotate clockwise, causing the negative ion emitter 11 to rotate out of the cleaning groove 18. Then, the negative ion emitter 11 is aligned with the negative ion output hole 10, which facilitates the subsequent discharge of the tip of the negative ion emitter 11 to ionize the air and generate negative ions.

[0045] Simultaneously, the second micro motor 19 drives the brush plate 22 to reciprocate within the fan-shaped groove 21. During the reciprocating rotation, the surface of the brush plate 22 comes into contact with the receiving end (carbon brush) at the end of the negative ion ground wire 14. The rotating brush plate 22 then scrapes off the dust adhering to the receiving end (carbon brush) at the end of the negative ion ground wire 14, preventing dust from adhering to the tip (carbon brush) of the emitter end of the negative ion emitter head 11 and the receiving end (carbon brush) at the end of the negative ion ground wire 14, thus improving the efficiency of the negative ion generator 6 in generating negative ions.
