Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a high-efficiency air filter element. Background Art

[0002] Air filters are also called air purification devices. With the rapid development of science and technology, people have higher and higher requirements for the quality of life. In order to ensure the health of people, air filters are widely used in home kitchens and bathrooms, clean workshops, clean factories, laboratories, clean rooms, and dust prevention of electronic machinery and communication equipment. However, paper air filter elements cannot be washed. After the filter element is washed with water, even if it is dried in the sun, the filter paper has been deformed and no longer has the previous effectiveness. Therefore, the air filter must not be washed with water. It is best to use a clean soft brush to brush off the dust on the surface along the folds of the filter element.

[0003] A Chinese utility model patent with publication number CN218451993U discloses a high-efficiency filter element for an air filter, comprising a base, telescopic rods are symmetrically fixedly connected to both sides of the top of the base, compression springs are arranged on the top sides of the two telescopic rods, a support platform is fixedly connected to the top of the telescopic rods, a knocking mechanism is symmetrically fixedly installed on the top of the base close to the inner side of the telescopic rods, the knocking mechanism comprises a fixed block, a rotating disk is fixedly installed on the side of the fixed block, a connecting block is rotatably connected to one side of the top surface of the rotating disk, and the connecting column is fixedly connected to the knocking block through the limit block.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device cleans the dust on the filter element by means of a soft-bristle brush that moves up and down. In the actual process, when the staff slides the fixed column up and down, the dust adhering to the filter element is easily scattered around under the action of the soft-bristle brush, which can easily cause the dust to escape to the vicinity of the air filter, resulting in a poor user experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a high-efficiency air filter element.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A high-efficiency air filter element comprises an outer frame, a slide groove is provided on the upper surface of the outer frame, a filter element main body is slidably arranged in the slide groove, a baffle for closing the slide groove is provided at the upper end of the inner wall of the slide groove, a mounting groove is provided on the side wall of the outer frame, an air intake plate for ventilation is installed in the mounting groove, a first placement groove is provided on the inner top wall of the outer frame, a rotating hole is provided on the inner wall of the first placement groove, a movable groove is provided on the inner wall of the first placement groove, a second placement groove is provided on the inner bottom wall of the outer frame, a cleaning component for cleaning the filter element main body is provided on the outer frame, and a sealing component for blocking dust is provided on the outer frame.

[0008] By adopting the above technical solution, when the staff activates the filter element body, the outside air moves into the outer frame through the air intake plate, and then the filter element body filters the air. After the filter element body has been used for a period of time, a large amount of impurities are easily attached to the filter element body. At this time, the staff needs to clean the filter element body. At this time, the staff needs to start the sealing component, so that the sealing component can form a partition between the air intake plate and the filter element body. Afterwards, the staff only needs to start the cleaning component to move the bristles up and down and clean the filter element body, thereby reducing the probability of dust on the filter element body moving outside the outer frame.

[0009] Furthermore, the closing assembly includes a rotating rod rotatably arranged in a rotating hole, a torsion spring with one end fixed to the side wall of the rotating rod, a barrier cloth with one end fixed to the side wall of the rotating rod, and a limiting rod fixed to the lower end of the barrier cloth, and the other end of the torsion spring is fixed to the inner wall of the rotating hole.

[0010] By adopting the above technical solution, when the staff needs to form a partition between the air intake plate and the filter element body, the staff needs to move the limit rod downward, so that the barrier cloth can move downward along with the limit rod, and then the barrier cloth forms a partition between the air intake plate and the filter element body, so that the barrier cloth can block the dust.

[0011] Furthermore, a first motor is arranged on the side wall of the outer frame, a rotating rod is fixed on the output shaft of the first motor, one end of the rotating rod away from the first motor is rotatably connected to the inner wall of the second mounting groove, a rotating block is arranged on the rotating rod, a connecting belt is fixed on the side wall of the rotating block, and the other end of the connecting belt is fixed to the bottom surface of the limiting rod.

[0012] Furthermore, the rotating block is rotatably connected to the rotating rod, and the rotational resistance between the rotating block and the rotating rod is much greater than the force required by the connecting belt to drive the limiting rod to move.

[0013] By adopting the above technical solution, when the staff needs to move the limit rod downward, the staff only needs to start the first motor to rotate the output shaft of the first motor, and then the rotating rod and the rotating block rotate with the output shaft of the first motor (at this time, the rotating rod and the rotating block rotate synchronously). Subsequently, when the limit block moves to the lowest point, the connecting belt is wrapped around the rotating block, the barrier cloth moves to the lowest point and forms a partition between the air intake plate and the filter element body, and the limit rod cannot continue to move, so that the force between the rotating block and the rotating rod gradually increases, and finally the rotating block and the rotating rod rotate relative to each other, thereby reducing the probability of the output shaft of the first motor being damaged by overheating due to stopping rotation.

[0014] Furthermore, an iron sheet is provided on the side wall of the barrier cloth close to the filter element body, and an electromagnet is provided on the inner wall of the movable groove close to the filter element body.

[0015] By adopting the above technical solution, when the barrier cloth moves downward following the limit rod, the staff only needs to energize the electromagnet to make the electromagnet adsorb the iron sheet, so that the barrier cloth is close to the inner wall of the moving groove close to the filter element body, thereby improving the barrier effect of the barrier cloth and further reducing the probability of dust moving outside the outer frame.

[0016] Furthermore, a cleaning groove is provided on the inner wall of the outer frame, and the cleaning assembly includes a cleaning rod slidably arranged in the cleaning groove, bristles arranged on the side wall of the cleaning rod, a second motor arranged on the upper surface of the outer frame, and a threaded rod fixed to the output shaft of the second motor, and the threaded rod passes through the cleaning rod and is threadedly connected.

[0017] Furthermore, a collecting groove is provided on the side wall of the outer frame, and a collecting box for collecting dust is slidably arranged in the collecting groove.

[0018] By adopting the above technical solution, when the staff needs to clean the filter element body, the staff needs to start the second motor to rotate the output shaft of the second motor, so that the threaded rod rotates with the output shaft of the second motor, and then the cleaning rod moves up and down under the action of the threaded rod, so that the bristles clean the side wall of the filter element body and the collection box collects the fallen dust, thereby reducing the difficulty of cleaning the filter element body for the staff.

[0019] Furthermore, a control switch is provided on the upper surface of the outer frame, and the control switch is electrically connected to the electromagnet.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff activates the filter element body, the outside air moves into the outer frame through the air intake plate, and then the filter element body filters the air. After the filter element body has been used for a period of time, a large amount of impurities are easily attached to the filter element body. At this time, the staff needs to clean the filter element body. At this time, the staff needs to start the sealing component, so that the sealing component can form a partition between the air intake plate and the filter element body. Afterwards, the staff only needs to start the cleaning component to move the bristles up and down and clean the filter element body, thereby reducing the probability of dust on the filter element body moving outside the outer frame at this time;

[0022] 2. In the present application, when the staff needs to move the limit rod downward, the staff only needs to start the first motor to rotate the output shaft of the first motor, and then the rotating rod and the rotating block rotate along with the output shaft of the first motor (at this time, the rotating rod and the rotating block rotate synchronously). Subsequently, when the limit block moves to the lowest point, the connecting belt is wrapped around the rotating block, the barrier cloth moves to the lowest point and forms a partition between the air intake plate and the filter element body, and the limit rod cannot continue to move, so that the force between the rotating block and the rotating rod gradually increases, and finally the rotating block and the rotating rod rotate relative to each other, thereby reducing the probability of the output shaft of the first motor being damaged by overheating due to stopping rotation;

[0023] 3. In the present application, when the barrier cloth moves downward following the limit rod, the staff only needs to energize the electromagnet to make the electromagnet adsorb the iron sheet, so that the barrier cloth is close to the inner wall of the moving groove close to the filter element body, thereby improving the barrier effect of the barrier cloth, and further reducing the probability of dust moving outside the outer frame.

A collecting groove 83 is provided on the side wall of the outer frame 1. The collecting box 84 is a rectangular parallelepiped structure with an upper end opening. The collecting box 84 is slidably arranged in the collecting groove 83 for collecting dust.

[0035] When the staff needs to clean the filter element body 21, the staff needs to start the second motor 53 to rotate the output shaft of the second motor 53, so that the threaded rod 54 rotates with the output shaft of the second motor 53, and then the cleaning rod 51 moves up and down under the action of the threaded rod 54, so that the bristles 52 clean the side walls of the filter element body 21, and the collection box 84 collects the fallen dust, thereby reducing the difficulty of cleaning the filter element body 21 for the staff.

[0036] A first placement groove 55 is provided on the inner top wall of the outer frame 1, a rotation hole 56 is provided on the inner wall of the first placement groove 55, a movable groove 57 is provided on the inner wall of the rotation groove, and a second placement groove 58 is provided on the inner bottom wall of the outer frame 1.

[0042] The use principle of a high-efficiency air filter element in this embodiment is:

[0043] When the staff activates the filter element body 21, the outside air moves into the outer frame 1 through the air intake plate 4, and then the filter element body 21 filters the air. After the filter element body 21 has been used for a period of time, a large amount of impurities are easily attached to the filter element body 21. At this time, the staff needs to clean the filter element body 21. At this time, the staff needs to start the sealing component 6, so that the sealing component 6 can form a partition between the air intake plate 4 and the filter element body 21. Afterwards, the staff only needs to start the cleaning component 5 to move the bristles 52 up and down and clean the filter element body 21, thereby reducing the probability of dust on the filter element body 21 moving to the outside of the outer frame 1.
