Description

Technical Field

[0001] The utility model belongs to the technical field of automotive parts, and particularly relates to a device for purifying an automotive air-conditioning system and an automotive air-conditioning system. Background Art

[0002] Currently, the main method to solve the problems of bacteria or viruses and peculiar smell in automotive air is to use a multi-effect filter element. However, its effect is limited. Only when the air containing bacteria passes through the filter element can it kill the bacteria in the air (a passive method). However, when using a filter element without antibacterial effect, the filter element may get moldy. At the same time, when the air-conditioner is in the cooling mode, when the air encounters the evaporator, due to the low temperature, water vapor will condense into liquid water. Over time, the water adhering to the surface of the evaporator will breed bacteria and mold, resulting in the air blown out by the air-conditioning system having a peculiar smell.

[0003] To solve the problems of mold and peculiar smell, some companies have designed antibacterial modules adapted to the air-conditioning system. For example, BYD's Green Clean System and Valeo's Mustard Antibacterial Pen, etc. (active methods). They can continuously release antibacterial substances, which diffuse into different parts of the air-conditioning system through the air, thereby killing bacteria and mold and reducing the generation of peculiar smell. However, they are generally installed on or below the filter element, mainly solving the problems of the filter element getting moldy and the peculiar smell generated after getting moldy. And due to the limited action space, the amount of antibacterial substances reaching the evaporator end is less, weakening its antibacterial ability and causing an unpleasant smell at the air-conditioning outlet.

[0004] Therefore, there is an urgent need for a purification device at present, which can be installed in an automotive air-conditioning system to actively purify the air-conditioning system, improve the problem that the antibacterial effect of all components inside the air-conditioning system is not ideal, and reduce the generation of peculiar smell in the automotive cockpit.

[0141] The housing 2 is the pipeline housing 2 on the positive - pressure side of the automotive air - conditioning system, and can be transmitted along the internal air flow of the air - conditioning system to the evaporator, so that the antibacterial substance 5 acts on the evaporator.

[0142] Please refer to Figure 3 As shown, the purification device is arranged on the positive - pressure side of the automotive air - conditioning system. After being inserted into the pipeline through the hole on the housing 2, the purification device is assembled on the housing 2 through the assembly structure 1 and the sealing structure 3. After the installation on the positive - pressure side of the automotive air - conditioning system is completed, the antibacterial substance 5 stored in the storage structure 4 can be sprayed into the air through the spray diffusion structure, inhibiting the growth of surrounding bacteria and other microorganisms and removing odor molecules. There is no odor when the automotive air - conditioner is turned on.

[0143] The above description of the embodiments is for the convenience of those of ordinary skill in the art to understand and use the utility model. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative labor. Therefore, the utility model is not limited to the above - mentioned embodiments, and the improvements and modifications made by those skilled in the art without departing from the scope of the utility model according to the disclosure of the utility model should be within the protection scope of the utility model.
