[0022] 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a negative ion air purifier, 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.

[0024] 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 negative ion generator 6 is located on one side of the upper surface of the middle shell 1. A negative ion output hole 10 is opened on one side of the edge of the middle shell 1. A T-shaped branch pipe is located on the upper surface of the middle shell 1 corresponding to the position of the negative ion output hole 10. A negative ion emitter 11 corresponding to the negative ion output hole 10 is located in one end of the T-shaped branch pipe. The negative ion generator 6 and the negative ion emitter 11 are electrically connected by a wire. A negative ion output groove 12 is opened on one side of the lower surface of the bottom cover 4. A fixing frame 13 is located on the upper surface of the bottom cover 4. 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 negative ion output groove 12. The negative ion generator 6 and the negative ion ground wire 14 are electrically connected by a wire.

[0025] The negative ion generator 6 is controlled by the PLC control board 8. An electric field is formed 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, thus purifying the air and replenishing it with negative ions.

[0026] 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. This device processes the input DC or AC power through an EMI processing circuit and a lightning protection circuit, then steps it up to a high AC voltage through a pulse circuit, overvoltage current limiting, and high / low voltage isolation circuits. After rectification and filtering by special-grade electronic materials, a pure DC negative high voltage is obtained. This DC negative high voltage is connected to a release tip made of metal or carbon (the emitting tip of the negative ion emitter 11). The high DC high voltage at the tip (the emitting tip of the negative ion emitter 11) generates a high corona discharge, rapidly releasing a large number of electrons (electrons). - Electrons cannot exist in the air for long (the lifespan of an electron is only on the order of nanoseconds), and they are immediately captured by oxygen molecules (O2) in the air, thus generating negative air ions.

[0027] The upper surface of the middle shell 1 is equipped with a fan 9 at the center. The output end of the fan 9 corresponds to the negative ion emitter 11. The fan 9 is controlled by the PLC control board 8. When the negative ion generator 6 and the negative ion emitter 11 generate negative air 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 negative air ions around the negative ion output hole 10 and increasing the space for negative ion air purification.

[0028] The upper surface of the middle shell 1 is provided with a duct cover 7 that covers the fan 9, and a duct is formed below the duct cover 7 that blows towards the negative ion output hole 10; an air inlet is opened on one side of the edge of the middle shell 1, and the outside air is connected to the duct through the air inlet. When the fan 9 is working, the outside air of the purifier enters the upper surface of the middle shell 1 through the air inlet, and then blows towards the negative ion output hole 10 along the duct.

[0029] 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 and the fan 9 respectively, and controls the operation of the humidifier 5, the negative ion generator 6 and the fan 9 through the PLC controller 8.

[0030] The bottom cover 4 has a bottom shell 15 covering the fixing frame 13 on its upper surface. At the same time, a counterweight is installed on the fixing frame 13 to increase 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, thus preventing the purifier from tipping over.

[0031] Working principle: When in use, the humidifier 5 and the negative ion generator 6 are combined. The humidifier 5 humidifies the indoor air, and an electric field is formed 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. In this way, the purifier can humidify the indoor air from the top and generate negative ions to remove dust, improving the practicality of the purifier.

[0032] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
