Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, and in particular to a heat dissipation device for a vacuum cleaner. Background Technology

[0002] A vacuum cleaner is a household appliance that uses a high-speed rotating internal motor to generate negative pressure, thereby sucking in and filtering dust and impurities from the air. Its working principle is that the motor drives the surrounding blades to rotate at high speed, creating a momentary vacuum inside the vacuum cleaner. This creates a negative pressure difference with the external atmospheric pressure, drawing in dust-laden air and expelling filtered, clean air from the vacuum cleaner's outlet.

[0003] During vacuum cleaner use, the air intake filter continuously captures and filters dust, particles, and other impurities from the air. However, after prolonged use, the filter can become clogged due to the accumulation of impurities. This not only affects the vacuum cleaner's suction power and filtration efficiency but also makes it difficult for the return airflow to cool the motor.

[0004] Therefore, a vacuum cleaner heat dissipation device is proposed to address the above problems. Utility Model Content

[0009] In one embodiment of this utility model, rubber pads are symmetrically fixed to the ends of the horizontal plate; the surface of the rubber pads is an arc-shaped structure; by setting the rubber pads, because the rubber pads are flexible materials, the rubber pads will come into contact with the vertical plate before the horizontal plate strikes the vertical plate, further reducing the direct contact between the horizontal plate and the vertical plate, reducing the noise and impact generated when the horizontal plate strikes the vertical plate, making the shell more convenient to use.

The cooling water in the water tank will absorb the heat generated by the motor under the action of heat conduction, thereby reducing the heat accumulated inside the housing and realizing the auxiliary heat dissipation of the motor by the device.

[0011] In one embodiment of this utility model, the fixing component includes a pair of crossbars; the crossbars and the water tank are fixedly connected; a plurality of elastic plates are fixedly connected to the middle of the crossbars; a pair of grooves corresponding to the crossbars are opened on the inner wall of the housing; when the water tank needs to be installed inside the housing, the water tank can be slid into the housing through the handle on one side of the water tank.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figures 1 to 5As shown, a vacuum cleaner heat dissipation device of this utility model includes a housing 1, with a partition 12 installed on the inner wall of the housing 1; a sealing bag 13 is provided at the bottom of the partition 12; a filter screen 14 is installed at the bottom of the partition 12 by bolts; a mounting plate 15 is fixedly connected to the top of the partition 12; a motor 16 is installed inside the mounting plate 15; a rotating impeller assembly 17 is fixedly connected to the output end of the motor 16; the rotating impeller assembly 17 is located inside the mounting plate 15; a horizontal plate 18 is provided at the bottom of the rotating impeller assembly 17; the two ends of the horizontal plate 18 are protruding; the horizontal plate 18 and the output end of the motor 16 are both fixedly connected; multiple vertical plates 19 are rotatably connected to the bottom of the partition 12; a ball 110 is fixedly connected to the bottom of the vertical plate 19; the vertical plate 19 is located inside the filter screen 14; when the housing 1 is working, the motor 16 is energized and drives the rotating impeller assembly 17 to rotate. When the rotating impeller assembly 17 rotates, it generates airflow, which makes the inside of the sealing bag 13 a negative pressure state. The housing 1 can be cooled by a pipe. The suction nozzle is connected to perform vacuuming on the floor. When the motor 16 starts, the horizontal plate 18 also rotates. When the horizontal plate 18 rotates, the protruding parts at both ends of the horizontal plate 18 strike the vertical plate 19, causing the vertical plate 19 to shake under the impact. The vertical plate 19 then rotates the ball 110 towards the inner wall of the filter screen 14, causing the ball 110 to strike the filter screen 14. This causes the dust and debris accumulated on the surface of the filter screen 14 to be removed or redistributed under the impact, reducing the clogging effect of these impurities on the filter screen 14. This ensures that the airflow can return through the filter screen 14 and cool the motor 16. Finally, the airflow is filtered through the top of the housing 1 and discharged. Through the cooperation of the horizontal plate 18 and the vertical plate 19, the rotation of the horizontal plate 18 drives the vertical plate 19 to strike the filter screen 14 with the ball 110, reducing the dust and impurities accumulated on the surface of the filter screen 14. This allows the airflow to return stably from the filter screen 14 to cool the motor 16 and ensures a suitable working environment for the motor 16.

When the first magnet 2 moves, the distance between the first magnet 2 and the second magnet 22 shortens, so that the vertical plate 19 will sway at a certain angle under the repulsive force of the magnetic force before being hit by the horizontal plate 18, thereby reducing the force generated by the collision between the horizontal plate 18 and the vertical plate 19, and reducing the burden on the horizontal plate 18 from hitting the vertical plate 19; through the cooperation of the first magnet 2 and the second magnet 22, the vertical plate 19 will pre-rotate under the magnetic force of the first magnet 2 and the second magnet 22, reducing the reaction force on the horizontal plate 18 from hitting the vertical plate 19, and extending the service life of the horizontal plate 18.

[0027] Reference Figure 4 As shown, a plurality of ball bearings 3 are symmetrically and rotatably connected in the middle of the horizontal plate 18; the ball bearings 3 are arranged in a circumferential array; by setting the ball bearings 3, when the horizontal plate 18 and the vertical plate 19 come into contact, the ball bearings 3 will also come into contact with the horizontal plate 18 and rotate, so as to reduce the wear caused by friction between the horizontal plate 18 and the vertical plate 19 and extend the service life of the horizontal plate 18 and the vertical plate 19.

[0028] Reference Figure 4 As shown, rubber pads 4 are symmetrically fixed to the ends of the horizontal plate 18; the surface of the rubber pads 4 is an arc-shaped structure; by setting the rubber pads 4, because the rubber pads 4 are flexible materials, the rubber pads 4 will contact the vertical plate 19 before the horizontal plate 18 strikes the vertical plate 19, further reducing the direct contact between the horizontal plate 18 and the vertical plate 19, reducing the noise and impact generated when the horizontal plate 18 strikes the vertical plate 19, making the housing 1 more convenient to use.

[0029] Reference Figure 2 and Figure 5 As shown, a water tank 5 is slidably fitted in the middle of the housing 1; the motor 16 is located inside the water tank 5; a fixing component for stabilizing the water tank 5 is provided in the middle of the water tank 5; when using the housing 1 for vacuuming, the fixing component can be used to release the water tank 5 and slide the water tank 5 out of the housing 1, then cooling water can be added into the water tank 5 and the water tank 5 can be reinstalled into the housing 1. The cooling water in the water tank 5 will absorb the heat generated by the motor 16 under the action of heat conduction, thereby reducing the heat accumulated inside the housing 1 and realizing the auxiliary heat dissipation of the motor 16 by the device.

[0030] Reference Figure 5 As shown, the fixing assembly includes a pair of crossbars 6; the crossbars 6 and the water tank 5 are fixedly connected; multiple elastic plates 62 are fixedly connected to the middle of the crossbars 6; a pair of grooves corresponding to the crossbars 6 are opened on the inner wall of the housing 1; when the water tank 5 needs to be installed inside the housing 1, the water tank 5 can be slid into the housing 1 through the handle on one side of the water tank 5. At this time, the crossbars 6 will enter the grooves inside the housing 1, and the elastic plates 62 will be deformed under the squeezing action. When the water tank 5 is completely inside the housing 1, the handle can be released. At this time, the water tank 5 will be fixed inside the housing 1 under the friction of the elastic plates 62 and the grooves, realizing the quick fixing of the water tank 5 by the device.

[0031] Reference Figure 5 As shown, multiple fins 7 are fixed to the inner wall of the water tank 5; the fins 7 are arranged in an array; by setting the fins 7, the cooling water in the water tank 5 can absorb the heat accumulated in the cavity between the shell 1 and the mounting plate 15 through the water tank 5 and the fins 7, thereby increasing the contact area of ​​the cooling water for heat exchange with the shell 1.

[0032] Reference Figure 4 As shown, the two ends of the horizontal plate 18 are arc-shaped; by setting the two ends of the horizontal plate 18 to arc shape, the resistance encountered by the horizontal plate 18 when it strikes the vertical plate 19 is smaller, further reducing the impact between the horizontal plate 18 and the vertical plate 19.

[0033] Working principle: When the housing 1 is working, the motor 16 is energized and drives the impeller assembly 17 to rotate. The rotation of the impeller assembly 17 generates airflow, creating a negative pressure state inside the sealed bag 13. The housing 1 can be connected to a suction nozzle through a pipe to perform dust collection on the ground. When the motor 16 starts, it also causes the horizontal plate 18 to rotate. When the horizontal plate 18 rotates, the protruding parts at both ends of the horizontal plate 18 strike the vertical plate 19, causing the vertical plate 19 to shake under the impact. The vertical plate 19 then carries the ball 110 towards the inner wall of the filter screen 14, causing the ball 110 to strike the filter screen 14. This causes the dust and debris accumulated on the surface of the filter screen 14 to be removed from the filter screen 14 or redistributed under the impact, reducing the impact of these impurities on the filter screen 14. The blocking effect ensures that the airflow can return through the filter screen 14 and cool the motor 16. Finally, the airflow will be discharged after being filtered through the top of the housing 1. Through the cooperation of the first magnet 2 and the second magnet 22, the first magnet 2 will move with the horizontal plate 18 when it rotates. When the first magnet 2 moves, the distance between the first magnet 2 and the second magnet 22 will shorten. This will cause the vertical plate 19 to sway at a certain angle under the repulsive force of the magnetic force before being hit by the horizontal plate 18, thereby reducing the force generated by the collision between the horizontal plate 18 and the vertical plate 19 and reducing the burden on the horizontal plate 18 from hitting the vertical plate 19. By setting the ball bearing 3, when the horizontal plate 18 and the vertical plate 19 come into contact, the ball bearing 3 will also come into contact with the horizontal plate 18 and rotate, thereby reducing The wear caused by friction between the horizontal plate 18 and the vertical plate 19 is mitigated. By incorporating a rubber pad 4, which is made of flexible material, the rubber pad 4 contacts the vertical plate 19 before the horizontal plate 18 strikes it, further reducing direct contact between the two plates and minimizing noise and impact. When using the housing 1 for vacuuming, the water tank 5 can be released from its fixation by the fixing assembly and slid out of the housing 1. Cooling water can then be added to the water tank 5 and it can be reinstalled into the housing 1. The cooling water in the water tank 5 absorbs the heat generated by the motor 16 through heat conduction, thereby reducing heat buildup inside the housing 1. Heat; when the water tank 5 needs to be installed inside the housing 1, the water tank 5 can be slid into the housing 1 through the handle on one side of the water tank 5. At this time, the crossbar 6 will enter the groove inside the housing 1, and the elastic plate 62 will be deformed under the pressure. When the water tank 5 is completely inside the housing 1, the handle can be released. At this time, the water tank 5 will be fixed inside the housing 1 by the friction between the elastic plate 62 and the groove. By setting the fins 7, the cooling water in the water tank 5 will absorb the heat accumulated in the cavity between the housing 1 and the mounting plate 15 through the water tank 5 and the fins 7. By setting the protrusions at both ends of the cross plate 18 to be arc-shaped, the resistance when the cross plate 18 hits the vertical plate 19 is smaller, further reducing the impact between the cross plate 18 and the vertical plate 19.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
