Description

TECHNICAL FIELD

[0001] The utility model relates to air purifier technical field, specifically air purifier shell's hardware connecting piece. BACKGROUND

[0002] Air purifier is a device for removing indoor air pollutants, which can effectively improve air quality and protect human health. Typical air purifiers use physical filter, activated carbon adsorption, electrostatic dust collection and other technical means to purify particulate matter, harmful gases and bacteria in the air. In modern families and office environments, air purifiers are becoming more and more popular, which puts higher requirements on their design and ease of use.

[0003] The basic structure of air purifier includes shell, fan, filter assembly and control system. Among them, the shell not only plays the role of protecting the internal elements, but also undertakes the task of aesthetic design, so as to integrate into different use environments. In order to facilitate user maintenance and replacement of internal filter, many air purifiers are designed with a detachable side plate part to facilitate quick access to internal components.

[0004] At present, the detachable side plate of air purifier shell is mainly fixed by the following methods:

[0005] 1. Bolt locking: this is the most common fixing method, which connects the side plate with the main body by bolts. Although this method is firm, it is easy to cause thread slipping or bolt loss during long-term use or frequent disassembly, affecting the stability of the connection. In addition, disassembling the bolt needs tools, which is relatively troublesome to operate.

[0006] 2. Buckle type connection: many manufacturers use plastic or metal buckle devices to fix the side plate through the elastic material properties of the buckle. This method is convenient to disassemble, but when the buckle material is integrated and aged, it is easy to cause loose or buckle breakage.

[0007] 3. Magnetic connection: use strong magnet to attract the side plate to the main body, which is very convenient to disassemble and can reduce the risk of appearance damage. However, the disadvantage of this method is that the strength of magnetic force needs to be accurately controlled, which is easy to loosen when it is weak, and difficult for users to disassemble when it is strong.

[0008] 4. Slide rail embedding: the side plate is embedded in the main body frame through the slide rail structure, which can realize quick plug and play. Such design needs accurate processing to ensure smooth sliding and accurate positioning, but may appear stuck after dust accumulation or component wear.

[0009] In summary, the existing connection mode or more or less there are some limitations. For example, bolted firm but cumbersome operation, integrated buckle convenient but easy to break. Therefore, the development of a new hardware connector is essential to meet the air purifier in fast, stable, durable, etc. comprehensive needs, and to enhance product competitiveness and user satisfaction, in view of this, we propose air purifier shell hardware connector.
