[0003] Given that the existing technology and the general-purpose design of this product meet the needs of most users, the inventors found in practice that the air conditioner vent and surrounding area are prone to blackening.

[0004] The present invention aims to solve the above-mentioned technical problems and provides a negative ion generator device for central air conditioning outlets, which can prevent the area near the central air conditioning outlet from being blackened due to the adsorption of airborne particles.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] This utility model provides a negative ion generator device for a central air conditioning outlet, comprising a main body on which a negative ion generator is installed. The main body has a front cover 1 and a rear cover 2, and the carbon brush of the negative ion generator is installed in a cavity formed by the front and rear covers. The above structure can be referred to in CN 216159196 U, which discloses a negative ion generator device for a central air conditioning outlet with self-cleaning function, and will not be described in detail here.

[0019] Through long-term practice, the inventors discovered that after a period of use, the surface of the equipment near the air outlet of the central air conditioning unit with self-cleaning function turns black. In view of this, the inventors have provided a corresponding solution by adding a conductive integrated cover to the central air conditioning unit with self-cleaning function to avoid the above-mentioned problem.

[0020] See Figure 1-2 The front cover of the negative ion generator device at the air outlet of the central air conditioner is equipped with a conductive integrated cover 3. Since the conductive integrated cover has conductive properties, it can quickly conduct static electricity in the vicinity of the cover through the grounding terminal, thereby reducing or minimizing blackening and other phenomena on the surface of the central air conditioner near the negative ion output port. In this embodiment, the conductive integrated cover has several outlets formed by several interlaced strips. The width and thickness of the strips can increase the strength of the air outlet side of the conductive integrated cover. More importantly, the width of the strips is usually selected to be greater than 0.8-4cm and the height is 0.5-2cm, which can also effectively increase the effective contact area between the conductive integrated cover and the air, making the adsorption of static electricity more efficient. The conductive integrated cover is electrically connected to the grounding terminal of the negative ion generator device at the air outlet of the central air conditioner.

[0021] It should be noted that the conductive integrated cover is provided with a circular hole facing the discharge carbon brush. The circular hole has a radius of 3-8 cm around the discharge carbon brush as the center. This expanded circular hole does not affect the efficiency of negative ion release, and can adsorb static electricity through the circumferential circular hole frame and conduct it to the grounding terminal through the adjacent strip.

[0022] See Figure 3-4 As shown, the conductive integrated cover has a rectangular frame 3a, which increases the contact surface of the cover's edge. The rectangular frame is divided into a front rectangular frame 3a-1 and a rear rectangular frame 3a-2 by a vertical frame 3b. The vertical frame can abut against the surface of the front cover, and the grounding path can be expanded by contacting the fixing screws of the front and rear covers. Triangular connecting blocks 3c are provided between the rear rectangular frame 3a-2 and the vertical frame 3b, and between the front rectangular frame 3a-1 and the vertical frame 3b. The triangular connecting blocks can increase the structural strength of the vertical frame.

[0023] See Figure 4 The triangular connecting blocks are symmetrically distributed vertically between the front rectangular frame 3a-1 and the vertical frame 3b, and each symmetrically distributed triangular connecting block has a vertically distributed strip at its corresponding position.

[0024] In addition, the conductive integrated cover is made of a first material, which is a conductive material, such as metal, and can be stamped into a single piece. Of course, the conductive integrated cover can also be made of a second material, the surface of which is coated with a conductive material. The second material is a non-conductive material. One option is to use a second material such as plastic to injection mold the basic structure of the conductive integrated cover, and then coat the surface with a conductive coating.

[0025] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
