Description

Technical Field

[0001] The utility model relates to the technical field of filter fans, in particular to a plate-type primary filter fan structure. Background Art

[0002] The plate-type primary filter fan is an efficient and practical air purification device. It combines the dual functions of filtering and fan, and can effectively remove large particles of dust, hair, fiber and other impurities during the air circulation process. The device is mainly composed of a filter part and a fan part. The filter part adopts a plate structure, and its filter material is usually made of polyester fiber, glass fiber or synthetic fiber paper, etc. The fan part is responsible for generating airflow to filter the air through the filter. The fan adopts an efficient and energy-saving motor and high-quality fan blades, which can generate a stable and strong airflow to ensure that the air can flow smoothly during the filtering process.

[0003] For example, the Chinese patent "A plate-type primary filter" with announcement number CN21958001U includes an aluminum alloy frame, a T-shaped opening is provided at the top of the aluminum alloy frame, a sealing plate is provided at the top of the T-shaped opening, a filter element No. 1 and a filter element No. 2 are fixedly connected to the bottom of the sealing plate, and a disassembly mechanism and a limit mechanism are provided at the top of the aluminum alloy frame; the disassembly mechanism includes a slot provided on both sides of the sealing plate, grooves are provided on both sides of the T-shaped opening, and sliding holes are provided at the top of the grooves. , a No. 1 spring is fixedly connected to one side away from the two grooves, a clamping block is fixedly connected to the end of the No. 1 spring, and the clamping block is slidably connected to the groove, a slider is fixedly connected to the top of the clamping block, and a slide is fixedly connected to the top of the slide, the limiting mechanism includes a slide groove, a No. 2 spring, a sliding clamping plate, an L-shaped plate and a limiting groove, a slide groove is opened on the top of the slide, a No. 2 spring is fixedly connected to the bottom end of the slide groove, a sliding clamping plate is fixedly connected to the top of the No. 2 spring, and the sliding clamping plate is slidably connected to the slide groove.

[0004] Although the above-mentioned existing technology can achieve primary filtration, in actual use, on the one hand, the body inspection and disassembly is not convenient enough. The body side panel must be removed by removing the screws before inspection and maintenance, which makes the removal steps of the body side panel cumbersome, thereby reducing the efficiency of body inspection. On the other hand, the plate-type primary effect is not flexible enough to move. When checking whether the plate-type primary effect needs to be replaced after a period of use, the plate needs to be removed and observed, which reduces the efficiency of plate-type primary effect inspection. Therefore, it does not meet existing needs. In this regard, we propose a plate-type primary-effect filter fan structure. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can make the machine body maintenance more convenient through the baffle and the magnetic strip. When maintenance is needed, pull the handle to drive the baffle to rotate. At the same time, the baffle and the magnetic strip on the machine body are separated from each other and the torsion spring is in a compressed state. At this time, after the baffle is rotated 180°, the front end of the machine body is in an open state, and then the operator performs maintenance work. When the maintenance is completed, the baffle is rotated 180° again by the handle. At this time, the magnetic strip on the baffle is mutually attracted with the magnetic strip on the machine body through magnetic force, so that the baffle blocks the opening of the front end of the machine body, thereby improving the removal efficiency of the side panel of the machine body, thereby speeding up the efficiency of the maintenance work.

[0017] 2. The utility model can quickly move the plate-type primary effect through the guide rail and the pulley. During maintenance, after the fan maintenance is completed, the plate-type primary effect is pulled outward to move the connecting rod on the plate-type primary effect in the guide rail. At this time, the pulley on the connecting rod slides inside the guide rail, and the plate-type primary effect is smoothly moved by the pulley until the plate-type primary effect is pulled out of the machine body. After the inspection of the plate-type primary effect is completed, the connecting rod on the plate-type primary effect is aligned with the opening of the guide rail and pushed into the guide rail, and the plate-type primary effect is continued to be pushed until the plate-type primary effect returns to its original position, making the inspection of the plate-type primary effect more convenient, thereby reducing the blind spots in the inspection.

[0018] 3. The utility model can absorb the vibration generated when the fan is working through the fixed seat and the rubber pad. When filtering, the motor is started to make the output shaft of the motor drive the driving pulley to rotate. At this time, the belt on the driving pulley drives the transmission pulley to rotate. At this time, the vibration generated when the motor and the fan are working is transmitted to the base through the machine body. The rubber pad on the base absorbs the vibration on the base by deformation until the vibration stops. At this time, the rubber pad releases the absorbed energy by resetting. The force generated during the resetting process of the rubber pad pushes the machine body to return to its original position, which is conducive to the stability and safety of the machine body operation.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1-4 The utility model provides an embodiment: a plate-type primary filter fan structure, including a base 1, an organic body 2 is fixedly arranged on the upper end of the base 1; and also includes:

[0026] A mounting seat 19 is arranged at the upper and lower ends of both sides of the front end of the outer body 2, and the mounting seat 19 is fixedly connected to the body 2. A rotating rod 21 is arranged between the mounting seat 19 and the same side of the body 2. The rotating rod 21 is rotatably connected to the mounting seat 19.

[0028] During use, when maintenance is needed, pull the handle 23, and the baffle 20 is driven to rotate by the handle 23. At the same time, the baffle 20 and the magnetic strip 18 on the body 2 are separated from each other and the torsion spring 22 is in a compressed state. At this time, after the baffle 20 is rotated 180°, the front end of the body 2 is in an open state, and the operator performs maintenance work again. When the maintenance is completed, the baffle 20 is rotated 180° again by the handle 23. At this time, the magnetic strip 18 on the baffle 20 is attracted to the magnetic strip 18 on the body 2 through magnetic force, so that the baffle 20 blocks the opening at the front end of the body 2.

[0029] See also Figure 1 and Figure 4 Magnetic strips 18 are fixedly arranged at the upper and lower ends inside the rear end of the baffle 20 and the upper and lower ends inside the front end of the body 2, and the positions of the magnetic strips 18 on the baffle 20 correspond to the magnetic strips 18 on the body 2, so that the baffle 20 can be fixed by the magnetic force between the magnetic strips 18.

[0030] See also Figure 1Two guide rails 12 are fixedly arranged at the upper and lower ends of one side inside the body 2, a plate-type primary effect 13 is arranged between the guide rails 12 on one side, and a plate-type high-efficiency filter 17 is arranged between the guide rails 12 on the other side, so as to facilitate filtering the gas through the plate-type primary effect 13 and the plate-type high-efficiency filter 17.

[0031] See also Figure 1 and Figure 4 Three connecting rods 14 are fixedly provided at the upper and lower ends of the plate-type primary effect 13 and the plate-type high-efficiency 17. The connecting rods 14 are equidistantly distributed and extend to the inside of the guide rail 12. Fixed rods 16 are fixedly provided on both sides of the connecting rods 14 located inside the guide rail 12. A pulley 15 is provided outside the fixed rod 16. The pulley 15 is rotatably connected to the fixed rod 16, and the pulley 15 is slidably matched with the guide rail 12, so that the movement of the plate-type primary effect 13 and the plate-type high-efficiency 17 is more stable through the pulley 15.

[0032] See also Figure 1 and Figure 2 A fixing seat 5 is fixedly provided at the four corners of the lower end of the base 1, a rubber pad 6 is provided at the lower end of the fixing seat 5, and the rubber pad 6 is connected to the fixing seat 5 by hot pressing, so that the vibration generated by the fan 7 and the motor 9 when working can be absorbed by the rubber pad 6.

[0033] See also Figure 1 and Figure 3 A fan 7 is arranged on the other side of the body 2, a transmission pulley 8 is arranged at the front end outside the fan 7, a motor 9 is fixedly arranged at the middle position inside the body 2, a driving pulley 10 is fixedly arranged outside the output shaft of the motor 9, a belt 11 is arranged outside the driving pulley 10, and the other end of the belt 11 is connected to the transmission pulley 8, so that the fan 7 can work through the cooperation of the motor 9 and the belt 11.

[0034] See also Figure 1 An air inlet 4 is provided inside one side of the body 2, and an air outlet 3 is provided inside the other side of the body 2, and the air outlet 3 is connected to the fan 7, so that the filtered gas can be discharged from the inside of the body 2 through the air outlet 3.

[0035] Working principle: After the inspection of the fan 7 is completed, the plate-type primary effect 13 is pulled outward, so that the connecting rod 14 on the plate-type primary effect 13 moves in the guide rail 12. At this time, the pulley 15 on the connecting rod 14 slides inside the guide rail 12, and the plate-type primary effect 13 moves smoothly through the pulley 15 until the plate-type primary effect 13 is pulled out of the body 2. After the inspection of the plate-type primary effect 13 is completed, the connecting rod 14 on the plate-type primary effect 13 is aligned with the opening of the guide rail 12 and pushed into the guide rail 12, and the plate-type primary effect 13 is continued to be pushed until the plate-type primary effect 13 is pulled out of the body 2. 13 is restored to its original position. When filtering, the motor 9 is started so that the output shaft of the motor 9 drives the driving pulley 10 to rotate. At this time, the belt 11 on the driving pulley 10 drives the transmission pulley 8 to rotate. At this time, the vibration generated by the motor 9 and the fan 7 when working is transmitted to the base 1 through the machine body 2. The rubber pad 6 on the base 1 absorbs the vibration on the base 1 by deformation until the vibration stops. At this time, the rubber pad 6 releases the absorbed energy by resetting. The force generated during the resetting process of the rubber pad 6 pushes the machine body 2 to return to its original position.
