Problems solved by technology

However, existing air filters generally have large air flow resistance, which affects the filtration efficiency of harmful substances in the air.
At the same time, the large air flow resistance also causes the air output of the filter to be small, which makes it difficult to supply the user with enough clean air to breathe, which seriously affects the comfort of the user.

Embodiment 1

[0036] Such as figure 1 Shown: an air filter 1, including a cover 11, a baffle 12 and a box body 13 that cover each other; a filter screen 2 is arranged between the cover 11 and the baffle 12; a fan 3 is arranged in the box body 13 The top wall of the cover 11 is provided with an air inlet 111; the panel of the baffle 12 is provided with a circular ventilation hole 121, and the panel of the baffle 12 is provided with an air guide strip 122; the side wall of the box body 13 is provided with an outlet The air outlet 131 ; the fan 3 drives the air to flow through the air inlet 111 , the filter screen 2 and the air hole 121 in sequence, and then flows out through the air outlet 131 . The cover body 11 , the baffle plate 12 and the box body 13 are detachably closed to facilitate assembly and disassembly, and also facilitate replacement of the filter screen 2 . The air guide bar 122 makes the air filtered by the filter screen 2 enter the fan 3 smoothly.

[0037] The air guide bar ...

Embodiment 2

[0039] On the basis of Example 1, such as image 3 As shown in , the air guide bar 122 is arc-shaped, and the clockwise direction of the arc radiation is opposite to the clockwise direction of the fan blade rotation. Through this arrangement, the air guide strip 122 is consistent with the actual direction of the air flow, and the air flow is smoother. When in use, the air guide bar 122 is in contact with the filter screen 2 , which can support and fix the filter screen 2 and prevent the filter screen 2 from hindering the airflow from entering the ventilation hole 121 . The filter screen covers the top wall of the cover. The edge of the baffle 12 is an annular flange 125 . The top wall 113 of the cover body 11 and the air guide bar 122 compress and fix the filter screen 2 , and the top wall 113 of the cover body 11 matches with the annular flange 125 on the edge of the baffle plate 12 and compresses the filter screen 2 . Through fitting and pressing, the baffle plate 12 and ...

Embodiment 3

[0041] Such as Figure 4 As shown: on the basis of Embodiment 1, the filter screen 2 covers the top wall of the cover body 11, and the top wall edge 112 of the cover body 11 matches with the upper edge 132 of the box body 13 and compresses the filter screen 2. Through fitting and pressing, the box body 13 and the filter screen 2 form a sealed cavity, which further improves the sealing performance.

[0042] Protruding blocks 114 are provided on the inner wall of the cover body 11 , and grooves 133 corresponding to and fitting with the positions of the protruding blocks 114 are provided on the outer side of the box body 13 . Through the fit and engagement of the protruding block 114 and the groove 133, it is convenient to disassemble and assemble, and also avoids air leakage, thereby improving the filtering effect. In this embodiment, the protrusions 114 are disposed at relative positions on the inner wall of the cover body 11 , and the grooves 133 are disposed at relative posi...

Abstract

The invention discloses an air filter which comprises a cover body, a baffle and a box body which are sequentially covered.A filter net is arranged between the cover body and the baffle.A fan is arranged inside the box body.An air inlet is formed in the top wall of the cover body.The baffle is provided with an air flow guiding strip and a circular vent hole.The side wall of the box body is provided with an air outlet.The fan drives air to sequentially flow through the air inlet, the filter net, the vent hole and the air outlet.According to the air filter, the filtering efficiency of suspended particles particularly PM2.5, bacteria, harmful gas and the like is high, air inside the air filter flows smoothly, the airtightness is good, the comfort of a user is high, and the air filter is particularly suitable for being adopted when it is cold.

Description

technical field [0001] The invention relates to air filtration and purification equipment, in particular to an air filter equipped with a power unit. Background technique [0002] Air pollution is the pollution of the atmosphere caused by substances that are harmful to human health and the surrounding environment. These substances may be gases, solid or liquid suspensions, etc. The smog that appears in a large area in China is a serious pollution phenomenon caused by solid or liquid suspensions formed by dust, sulfuric acid, nitric acid, organic hydrocarbons, etc. in the air and small water droplets in the air. [0003] Particulate matter with a diameter less than or equal to 2.5 microns is called fine particulate matter (PM2.5). Particulate matter can stay in the atmosphere for a long time, and can enter the body with breathing, accumulate in the trachea or lungs, and affect health. PM2.5 mainly causes damage to the respiratory system and cardiovascular system, including...
