Description

Title of the invention: Air Purifier

[0001] Technical Field

[0002] The present invention relates to the field of air purification technologies, and in particular, to an air purifier.

[0003] 3⁄4 body

[0004] In the existing air purification device, the air flow process is the air inlet _→ fan _→ filter _→ air outlet

In the patent CN202555096, the order of air flow is: air inlet→fan→filter→air outlet. In this design, the filter objectively hinders the air flow formed by the fan (because the fan Pushing the air through the filter), in this case, it will inevitably reduce the overall filtration effect of the air purifier. In the case of insufficient fan speed, the air flow rate filtered from the filter is not high, and will not be too large. Filtering effect.

[0021] t m^

[0022] In order to explain the technical content, the objects and effects achieved by the present invention in detail, the following embodiments are described in conjunction with the accompanying drawings.

[0023] The most critical idea of the present invention is that the air cleaner includes a casing 1, a fan 2, and a filter 3, and the filter 3 and the fan are sequentially disposed in an air passage between the air inlet 12 and the air outlet 11. 2. The present invention can improve the purification effect.

1 to 4, the air purifier of the present invention includes a casing 1, a fan 2 disposed in the casing 1, and a filter 3, the filter 3 is disposed obliquely, and the casing 1 is The air inlet 12 and the air outlet 11 are disposed. The air duct 12 is disposed in the casing 1 and communicates with the air outlet 11 , and the filter is sequentially disposed in the air passage between the air inlet 12 and the air outlet 11 . 3 and fan 2.

[0025] As can be seen from the above description, the present invention has the following advantages: In the air purifier of the present invention, the filter 3 and the fan 2 are sequentially disposed in the air passage between the air inlet 12 and the air outlet 11, and the fan 2 is disposed in the filter. Before the device 3, the air formed by the filter 3 against the fan 2 by the fan 2 pushing the air through the filter 3 can be avoided. The flow has a hindrance effect, and the invention utilizes the negative pressure principle to effectively enhance the overall filtering effect of the air purifier, and the air purifier of the structure enables the fan 2 to filter through the filter 3 even when the rotation speed is insufficient. The outgoing air has a higher flow rate, effectively filtering, and greatly improving the performance of the filter 3.

As can be seen from the above description, the advantage of using the tilt-mounted filter 3 is that it is placed vertically or horizontally.

In the case where the width or the upper and lower heights of the front and rear walls of the casing 1 are not increased, the area and volume of the filter 3 can be made larger, thereby increasing the purifying ability of the purifier.

[0027] Further, a fan cover 4 is disposed outside the fan 2, and the fan cover 4 includes a first port 41 and a second port 42. The first port 41 communicates with the air channel, and the second The cornice 42 communicates with the air outlet 11.

[0028] As can be seen from the above description, the provision of the fan cover 4 first serves to protect the fan 2, and the second makes it easier for the air in the fan 2 to flow out of the casing 1 along the rotation of the fan 2.

[0029] Further, the fan cover 4 includes an annular baffle 43 and a cover 4 connected to the side of the annular baffle 43.

4, the first port 41 is disposed on the cover 44, and the second port is disposed on the annular baffle 43

42.

[0030] As can be seen from the above description, the fan 2 is operated, and under the action of the baffle, the air in the fan 2 flows out of the casing 1 along the annular deflector 43 along the rotation of the fan 2.

[0031] Further, the air outlet 11 is disposed at an upper portion of the casing 1, the air inlet 12 is disposed at a lower portion of the casing 1, and a first support member 5 is disposed on an inner bottom surface of the casing 1 A second support member 6 is disposed on the inner side wall of the lower portion, and the two ends of the filter 3 are respectively connected to the first support member 5 and the second support member 6.

[0032] As can be seen from the above description, in the present embodiment, the filter 3 is inclined to the bottom of the casing 1, and does not form a swirling airflow at the bottom corner of the bottom, which is advantageous for the air flow in the casing 1, the purifier The air inlet 12 is located at the bottom of the side wall surface of the casing 1, and can directly suck the bottom air. The air outlet 11 is located at the top of the purifier and is vertically exhausted upward. This design increases the scope of the purifier purification cycle, and the purifier is indoors. The ability to clean air has been improved.

[0033] Further, the housing 1 is a rectangular box.

[0034] Further, the fan 2 is fixed on an inner side wall of the casing 1 and has a gap with the opposite inner side wall, and the gap communicates with the first port 41 of the fan 2, A wind deflector 7 is provided in the gap.

[0035] As can be seen from the above description, the wind deflector 7 is disposed obliquely above the first port 41, and the air is obscured at the windshield 7 After being blocked and stayed, it is then exhausted into the hood by the fan 2 and then discharged by the air outlet 11. This structure can effectively increase the rate at which the air fluid flows through the fan 2, thereby improving the purification efficiency.

Referring to FIG. 1 to FIG. 4, the first embodiment of the present invention is: The air purifier of the embodiment includes a casing 1, a fan 2 disposed in the casing 1, a fan cover 4, and a filter 3. The housing 1 is in the shape of a rectangular box. The housing 1 includes an air inlet 12, a duct and an air outlet 11.
