Detailed Description
In order to further describe the technical means and effects adopted by the present application to achieve the preset purpose, the following detailed description refers to the specific implementation, structure, characteristics and effects according to the present application with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
As shown in connection with fig. 1-5. The cyclone filter device specifically comprises a dust cup 1 with an air inlet 11, a cylindrical or conical HEPA filter 2 arranged at the upper end of the dust cup 1, a lower cover 3 arranged at the lower end of the HEPA filter 2 to seal the lower end of the HEPA filter 2, an upper cover 4 arranged at the periphery of the upper end of the HEPA filter 2 to fix the HEPA filter 2 in the upper end of the dust cup 1, and a wind deflector 51 and an air deflector 52 extending downwards from the upper cover 4. Wherein, the wind shield 51 is arranged at one side of the air inlet 11 and is positioned between the dust collecting cup 1 and the HEPA filter 2, and the wind shield 51 is used for guiding the cyclone entering the air inlet 11 to rotate along one direction of the air deflector 52 along with dust; the starting end 521 of the air deflector 52 is connected with the air deflector 51, and the tail end 522 of the air deflector 52 extends towards the inner wall of the dust cup 1 relative to the starting end 521 of the air deflector 52 to separate dust from the cyclone under the action of centrifugal force due to the centrifugal force generated in the process of rotating the dust along the air deflector 52, and the dust impacts the inner wall of the dust cup 1 and slides down along the inner wall of the dust cup 1 to sink into the bottom of the dust cup 1, thereby achieving the purpose of cyclone separation.
Wherein, upper cover 4, deep bead 51 and aviation baffle 52 are integrated into one piece structure to be convenient for production and processing and installation use.
In order to guide all the cyclone dust entering from the air inlet 11 to the air deflector 52 as much as possible, the height of the air deflector 51 is set to be greater than the height between the lower side edge of the air inlet 11 and the upper cover 4, so that the lower end of the air deflector 51 extends below the air inlet 11, as shown in fig. 5. And, the outer side of the wind deflector 51 is disposed in contact with the inner wall of the dust cup 1 to prevent the cyclone introduced from the air inlet 11 from rotating toward the wind deflector 52 with dust.
In order to make the cyclone generate centrifugal force continuously during the movement along the air deflector 52 to improve the separation effect of the dust, the starting end 521 of the air deflector 52 to the end 522 of the air deflector 52 are gradually extended towards the inner wall of the dust cup 1. For example, the air deflector 52 is formed by sequentially connecting a plurality of arc plates, and the last arc plate from the first arc plate of the starting end 521 to the tail end 522 gradually faces the inner wall of the dust collecting cup 1 and is far away from the HEPA filter 2, so that the cyclone can continuously generate centrifugal force to throw dust from the last arc plate to the inner wall of the dust collecting cup 1 in the moving process along the air deflector 52, then slide downwards along the inner wall of the dust collecting cup 1 and sink into the bottom of the dust collecting cup 1, and the purpose of cyclone separation is achieved. In addition, the radian between the starting end 521 of the air deflector 52 and the tail end 522 of the air deflector 52 exceeds half-circular radian, so that the air deflector 52 is covered on the outer side surface of at least half-circular radian of the HEPA filter 2 to improve the separation capability.
Therefore, after entering from the air inlet 11, the cyclone is blocked by the wind shield 51 and guided to the wind deflector 52 to continuously generate centrifugal force in the process of rotating in the dust cup 1, and finally, when the dust reaches the tail end 522 of the wind deflector 52, the dust is thrown to the inner wall of the dust cup 1 and then slides downwards along the inner wall of the dust cup 1 to sink into the bottom of the dust cup 1, so that the purpose of cyclone separation is achieved, and then, the cyclone airflow is discharged from the upper end of the HEPA filter 2 through the HEPA filter 2. Since most of the dust falls to the bottom of the dust cup 1 after being separated during the movement along the wind deflector 52, the cyclone air flowing through the hepa filter 2 has a smaller dust content, thereby reducing the amount of dust adsorbed by the hepa filter 2 and achieving the technical effects of improving the dust separation effect and prolonging the service life of the hepa filter 2.
Further shown in connection with fig. 6 and 7. The cyclone filter device of the invention can be used in a dust collector. The dust collector comprises a suction head 6 with a dust collection port, a support rod 7 with the lower end fixedly connected with the suction head 6, a handle 8 arranged at the upper end of the support rod 7, a host machine 9 fixed at the upper end of the support rod 7 or the lower end of the handle 8, and a cyclone filter device connected with the host machine 9; a cyclone channel 71 is arranged in the support rod 7, the lower end of the cyclone channel 71 is connected with the suction head 6, and the upper end of the cyclone channel 71 is communicated with the air inlet 11; and a blower for generating a suction vacuum force to generate cyclone in the cyclone passage 71 is provided in the main body 9, and a suction port 91 is provided at a lower end of the main body 9, and the suction port 91 is connected to an upper end of the hepa filter 2.
Wherein, the lower end of the dust cup 1 is provided with a concave buckling position 12, the upper end of the supporting rod 7 is provided with a convex buckling 72, and the supporting rod 7 is provided with an exposed upper end of the cyclone channel 71. When the cyclone filter device is mounted on the support rod 7, the buckle 72 provides support for the cyclone filter device and is buckled and connected with the buckling position 12 so as to fix the cyclone filter device on the support rod 7, at this time, the upper end of the cyclone channel 71 is communicated with the air inlet 11, and the air suction port 91 at the lower end of the host 9 is communicated with the upper end of the HEPA filter 2. Therefore, when the fan works to generate suction vacuum force, dust enters the suction head 6 from the dust collection opening and forms cyclone in the cyclone channel 71, then the cyclone brings the dust into the cyclone filter device from the air inlet 11, and clean air enters the suction opening 91 from the upper tail end of the HEPA filter 2 after the dust is separated from the cyclone filter device, so that dust collection operation is completed and dust collection effect is good.
The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, and alternatives falling within the spirit and principles of the present application.
