[0002] Negative ion air purifiers primarily work by generating negative ions and using them to purify air pollutants. They use an internal high-voltage generator or corona discharge method to produce negatively charged air molecules or oxygen negative ions. These negative ions actively capture harmful airborne substances such as dust, bacteria, and viruses. By binding to these pollutants, they settle or are adsorbed by filters, effectively removing impurities from the air. Negative ions also help improve indoor air quality by ionizing oxygen in the air into ozone, which has a certain antibacterial effect. They also promote the synthesis and storage of vitamins in the human body, enhance heart and lung function, and have a positive impact on human health.

The installation of a wireless charging device makes the air purifier more beautiful overall.

[0004] These prior arts all adopt the structure that the fan directly acts on the negative ion generator, that is, directly blows against it, which will cause the negative ions to accumulate in the purifier housing, resulting in poor purification effect. Utility Model Content

[0005] The utility model aims to solve the deficiencies in the prior art and provides a negative ion air purifier which can blow out the maximum concentration of negative ions in the body without causing internal accumulation.

[0006] In order to solve the above technical problems, the present invention solves them through the following technical solutions: a negative ion air purifier, comprising an air purifier housing, wherein the air purifier housing is divided into several working chambers by a partition structure, a fan, a PCB board and an ionization element are electrically connected and respectively arranged in each working chamber, the working chamber of the fan and the working chamber of the ionization element are interconnected, and a plurality of working holes communicating with the outside world are opened on the top of the housing corresponding to the working chamber where the ionization element is located.

[0007] In the above technical solution, the air purifier housing includes a detachable upper housing and a lower housing.

[0014] In the above technical solution, the third barrier block is provided with a plurality of notches, which cooperate with the third barrier block to form a communication channel between the first working chamber and the third working chamber.

[0015] In the above solution, a hook is provided on the rear working surface of the air purifier housing to facilitate installation.

[0016] Compared with the prior art, the utility model has the following beneficial effects: by connecting the working chamber of the fan and the working chamber of the ionization element through a connecting channel, the wind from the fan will not directly act on the ionization element, but will enter the working chamber of the ionization element through the connecting channel and be evenly distributed.

[0022] The present invention is described in further detail below with reference to the accompanying drawings.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0024] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0025] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0026] See also Figures 1 to 4 A negative ion air purifier includes an air purifier housing 1, which includes a detachable upper housing 12 and a lower housing 13. Of course, the housing 1 can also be made into an inseparable integral structure, but compared with the detachable structure, the inseparable structure will bring inconvenience in assembly. Therefore, in this solution, as a preferred embodiment, a detachable upper housing 12 and a lower housing 13 are used to realize the installation of internal components, and the connection method of the upper housing 12 and the lower housing 13 can be a snap connection, a bolt connection, etc.

[0027] In this solution, the upper shell 12 and the lower shell 13 both adopt a circular cross-section structure. Of course, they can also adopt a square or other shape structure that conforms to the actual situation.

[0028] Among them, the edge of the lower shell 13 is provided with a folded edge, and the first blocking block 131 and the second blocking block 132 are arranged in a ring from the inside to the outside on the inner working surface of the lower shell 13, so that three independent working chambers are formed on the lower shell 13, namely the first working chamber 14, the second working chamber 15 and the third working chamber 16.

[0029] An installation structure 141 is provided in the first working chamber 14 , and the fan 2 is provided in the first working chamber 14 through the installation structure 141 . In order to allow external air to enter, a plurality of air inlet holes 142 are provided at the bottom of the first working chamber 14 corresponding to the working position of the fan 2 .

[0030] The second working chamber 15 is arranged outside the outer circumference of the first working chamber 14 and is used to accommodate the PCB board 3 assembly and the high voltage generator 5 electrically connected thereto.

[0031] The third working chamber 16 is provided with an ionization element 4, including an ionization needle assembly. Several ionization needles are arranged on the ionization plate and are arranged in a ring in the third working chamber 16. The second working chamber 15 and the third working chamber 16 are separated by a second blocking block 132, which prevents the ionization element 4 from affecting the PCB board 3 assembly to the greatest extent.

[0032] Obviously, the fan 2 , the PCB board 3 and the ionization element 4 are all electrically connected.

[0033] The side of the lower shell 13 where the baffle structure is set is called the inner working surface, and the opposite side is called the outer working surface. A hook installation position is set on the outer working surface of the lower shell 13, and the hook 7 is installed on the outer working surface of the lower shell 13 through the installation position.

[0034] The upper shell 12 corresponding to the lower shell 13 is a disc-shaped structure, and its edge is also provided with a folding structure that matches the folded edge of the lower shell 13, so that a working chamber is formed inside when the lower shell 13 and the upper shell 12 are combined.

[0035] The inner working surface 120 of the upper shell is provided with a third partition block 121, and the setting of the third partition block 121 is located corresponding to the setting position of the second partition block 132, that is, the extended end of the third partition block 121 is against the bottom of the third working chamber 16, and the inner working surface of the third partition block 121 is fit with the outer working surface of the second partition block, and there is a gap between the inner working surface of the upper shell and the tops of the first partition block 131 and the second partition block 132 and the inner working surface of the upper shell 12.

[0036] Furthermore, a plurality of slots 1210 are provided on the third partition block 121, which cooperate with the third partition block 121 to form a connecting channel 6 between the first working chamber 14 and the third working chamber 16. In this way, the air brought by the fan 2 diffuses from the gap between the top of the first partition block 131 and the second partition block 132 and the inner working surface of the upper shell 12, and then diffuses from the connecting channel 6 into the third working chamber 16, contacts the ionization needle, and forms air with negative ions. This method of diffusing the air brought by the fan 2 through the connecting channel 6 can ensure the uniformity of the air output, allowing the ionized air molecules to pass through the holes on each edge, avoiding the defect of uneven air output caused by direct passage, and is conducive to maximizing the concentration of ionized air molecules without accumulation of internal concentration.

[0037] The upper shell can be described as the top of the upper shell according to the installation position, and a number of working holes 111 are opened at the position corresponding to the third working chamber 16, so that the air with negative ions formed in the third working chamber 16 is released from the working holes 111 to the external environment.

[0038] During operation, the device is hung on the top of the purification space by the hook 7, which is easy to install. After installation, the upper shell faces the ground. When negative high-voltage direct current is applied to the ionization element 4, the needle tip of the ionization needle will produce a large number of negative polarity ions. After the air comes into contact with the negative polarity ions, ionized air molecules are formed and released into the external environment through the working hole 111. They combine with debris objects in the air such as pollen, mold spores, dust, tobacco smoke, bacteria, etc. to achieve sedimentation, thereby achieving a purification effect.

[0039] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
