Description

Air purifier

Technical field

The invention relates to the field of air purification, and in particular to an air purifier.

Background technique

With the development of society and the improvement of living standards, more and more consumers are paying attention to and using air purifiers. Currently, existing air purifiers need to be cleaned or replaced after a period of use. If the bacteria and dirt inside the air purifier are not cleaned in time, the air purifier will not be able to purify the air, but will increase the pollution. In the current air purifier, a pre-filter, a HEPA filter, an activated carbon filter, and other filtering filters are usually disposed. For example, in the case of a pre-filter, it needs to be taken out of the air purifier during cleaning, rinsed under water and then returned to the air purifier. However, the above cleaning method is troublesome. In response to this, some air purifiers have been modified to clean the pre-filter inside. The patent application with the application number 201220267704.1 provides a self-cleaning air purifier, which is cleaned by the water sprayed from the water spray port by means of a water spray port connected with a water spray pipe to clean the parts which are easy to accumulate ash inside. Dirty water flows out from the bottom. However, the above patent still has the following problems: 1. The dirty water discharged from the bottom will pollute the use environment of the air purifier, increasing the burden of cleaning the indoor environment; 2. The water flow has some strong adhesion to the pre-filter. The dirt can not be cleaned effectively; 3. The HEPA filter is usually set after the front filter, and the general HEPA filter will affect the filtration effect if it is cleaned.

Summary of the invention

The invention provides an air purifier for solving the problem that the pre-filter cannot be effectively cleaned inside the air purifier in the prior art.

In order to solve the above technical problem, the present invention provides an air purifier comprising a body, a pre-filter and a HEPA filter. The pre-filter and the HEPA filter are disposed in the body, wherein the two bodies are relatively vertical. A sliding rail is disposed on the side wall, and the first sliding member and the second sliding member are disposed on the sliding rail, the first sliding member and the second sliding member are located in front of the front screen, and the second sliding member is located below the first sliding member. a spray pipe having a spray hole is arranged on the first sliding member, and a sponge strip facing the front filter mesh is arranged on the second sliding member, and the sponge strip is connected Touch the front filter.

In a preferred embodiment of the invention, a louver is disposed between the pre-filter and the HEPA filter.

In a preferred embodiment of the invention, the orifices of the water spray pipe are arranged in two rows at intervals.

The air purifier provided by the present invention cleans the front filter through the water jet of the spray pipe provided on the first sliding member, removes the dirt which is easy to be washed, and then passes the sponge provided on the second sliding member. The strip is wiped against the front screen to remove dirt with strong adhesion. By arranging the second sliding member under the first sliding member, the sponge strip on the second sliding member can absorb the dirty water after washing, thereby preventing the dirty water from flowing out. By arranging the louver between the front filter and the HEPA filter, the louver can be closed when cleaning the front filter to prevent the water sprayed from the spray hole during the cleaning process from cleaning the HEPA filter, thereby affecting the louver Filter the effect.

detailed description

As shown in FIG. 1 , the air purifier provided by the present invention includes a body 10 , a front screen 101 and a HEPA screen 102 . The front screen 101 and the HEPA screen 102 are disposed in the body 10 . A slide rail 104 is disposed on two opposite vertical sidewalls of the body 10. The slide rail 104 is provided with a first sliding member 105 and a second sliding member 106. The first sliding member 105 and the second sliding member 106 are located on the front screen 101. In front, the second slider 106 is located below the first slider 105. A water spray pipe 107 having an injection hole 108 is disposed in the first sliding member 105. Here, as shown in FIG. 2, the nozzle holes 108 in the water spout pipe 107 are arranged in two rows at intervals to ensure a wide and uniform flow of water to the pre-filter 101. The second slider 106 is provided with a sponge strip 109 facing the front screen 101, and the sponge strip 109 contacts the front screen 101.

Herein, the first sliding member 105 and the second sliding member 106 are connected to the driving mechanism and the control circuit inside the air purifier, and the automatic sliding is realized by the cooperation of the control circuit and the driving mechanism. The initial position of the first sliding member 105 is, for example, sliding. At the top of the rail 104, the initial position of the second slider 106 is, for example, the slide rail 104. At the bottom, the sliding stroke of the two is specifically: the first sliding member 105 slides from the top of the sliding rail 104 to the bottom, in the process, the nozzle hole 108 sprays water to the front screen 101, and the first sliding member 105 is reset from the bottom to the bottom. At the top, the spout 107 is closed while the second slide 106 slides from the bottom of the slide 104 to the top, after which the second slide 106 slides to the bottom to reset. However, the present invention is not limited thereto. In other embodiments, a slide switch may be disposed outside the side wall of the body 10 to directly control the sliding of the first slider 105 and the second slider 106. The sponge strip 109 disposed on the second sliding member 106 can wipe the pre-filter 101 after the water is flushed before the filter 101, and remove the dirt with strong adhesion on the pre-filter 101. Adsorb the dirty water after cleaning to solve the problem of dirty water flowing out and not easy to clean. In addition, an opening may be provided in the body 10 at the initial position of the second slider 106, and the sponge strip 109 may be replaced through the opening. In this way, the cleaning of the air purifier requires only the replacement of the sponge strip, and the sponge strip can be reused many times after cleaning, which also saves cost.

Here, the louver 103 is disposed between the front filter 101 and the HEPA filter 102, and the louver is opened and closed on the outside of the body 10. When the air cleaner is normally used, the louver 103 is set to an open state, that is, The blades of the louver are not closed; when the pre-filter 101 is cleaned, the louver 103 is placed in a closed state, that is, the blades of the louver are closed. That is, when the pre-filter 101 is cleaned, the louver 103 serves as a waterproof function to prevent the water flow during the washing process from being sprayed onto the HEPA filter 102, thereby affecting the filtering effect.

The above embodiments are not intended to limit the invention in any way, and all the technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
