Description

air purification equipment

technical field

The utility model relates to an air purification equipment, which belongs to the field of air purification equipment.

Background technique

Air purifier, also known as air cleaner, refers to the ability to absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), effectively Products that improve air cleanliness. There are many different technologies and media in an air purifier that enable it to provide clean and safe air to the user. At present, air purification technologies include: adsorption technology, negative (positive) ion technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc. Among them, high-efficiency filtration technology is more commonly used; the materials used in filtration technology mainly include: activated carbon, synthetic Fiber, HEAP high-efficiency materials, etc. The characteristics of the above-mentioned materials are that they basically need to be replaced regularly after a period of use. Therefore, the current air purifiers based on filtration technology have high maintenance costs. However, air purifiers based on negative (positive) ion technology and electrostatic dust collection technology have high manufacturing costs, making it difficult for these air purifiers to enter low- and middle-income families. The Chinese utility model patent titled "Centrifugal Air Purifier" with the application number "201410807431.9" discloses a centrifugal air purifier, which includes a cylindrical shell and a filter element arranged in the shell , the filter element is a plate made of water-absorbing material, the filter element is curled in a spiral shape, and after the filter element is curled, a gap is left between two adjacent filter element side walls to form a spiral ventilation channel in cross section; The casing is provided with an air inlet and an air outlet, and the two ends of the air passage communicate with the air inlet and the air outlet respectively. However, although the device can perform air filtration, the sterilization effect is relatively poor, so the air purification effect is not ideal.

Utility model content

In order to solve the above problems, the utility model designs an air purification device, which can not only filter the air, but also sterilize the air, and has a good air purification effect.

The technical scheme of the utility model is:

The air purification equipment includes a cylindrical shell, the shell is provided with a filter core, the filter core is provided with a layer of filter screen, and the surface of the filter screen is provided with a layer of filter paper, which improves the filtering effect, and the filter core is curled It is in a spiral shape. After the filter element is crimped, a gap is left between two adjacent filter element side walls to form a spiral ventilation channel in cross section; the end center of the shell is provided with an air inlet, and the side wall is provided with a An air outlet, the air outlet is located at the end of the filter element, the center of the filter element is provided with an ozone generator, and the ozone generator is used to disinfect the air in the housing with ozone, which improves the purification effect,

Further, an exhaust fan is also provided at the air outlet to make the air flow faster.

When in use, turn on the fan to make the air rotate at high speed in the ventilation channel, and the dust particles in the air will hit the side wall of the ventilation channel under the action of centrifugal force and be absorbed by the filter element on the surface of the side wall of the ventilation channel. At the same time, the air in the casing is disinfected by ozone through the ozone generator, which has high purification efficiency and low maintenance and manufacturing costs. .

The utility model has the advantages that not only air filtration but also air sterilization can be performed, and the air purification effect is good.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

The preferred embodiments of the present utility model are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Example 1

As shown in Figure 1, a kind of air purification equipment comprises a cylindrical shell 1, and the filter element 2 is arranged in the said shell 1, and said filter element 2 is provided with a layer of filter screen, and the surface of said filter screen is provided with There is a layer of filter paper, which improves the filtering effect. The filter element 2 is curled in a spiral shape. After the filter element 2 is curled, a gap is left between the side walls of the two adjacent filter elements 2 to form a spiral ventilation channel in cross section; The end center of the housing 1 is provided with an air inlet (not shown), and the side wall is provided with an air outlet 4. The air outlet 4 is located at the end of the filter element 2, and the center of the filter element 2 is provided with an ozone generator. 3. Ozone disinfection is carried out to the air in the casing 1 through the ozone generator 3, which improves the purification effect,

The air outlet 4 is also provided with an exhaust fan to make the air circulation more rapid.

When in use, turn on the fan to make the air rotate at high speed in the ventilation channel, and the dust particles in the air will hit the side wall of the ventilation channel under the action of centrifugal force and be absorbed by the filter element on the surface of the side wall of the ventilation channel. At the same time, the air in the casing is disinfected by ozone through the ozone generator, which has high purification efficiency and low maintenance and manufacturing costs.
