DETAILED DESCRIPTION

[0021] Please see Figures 1-5 This utility model provides a technical solution: a heat dissipation structure for a vacuum cleaner, including a body 1 and a dustproof device 4. A suction pipe 2 is provided on one side of the body 1, a vacuum cleaner 3 is installed on the upper surface of the body 1, heat dissipation holes are opened on the upper surface of the vacuum cleaner 3, and the dustproof device 4 is provided on the upper surface of the vacuum cleaner 3.

[0022] The specific setup and function of its dustproof device 4 and collection device 5 will be explained below.

[0023] In this implementation scheme: the dustproof device 4 includes a card holder 45, which is fixedly connected to the body 1. An outer frame 42 is rotatably connected to the surface of the card holder 45. A filter cloth 41 is fixedly connected to the inner wall of the outer frame 42. An iron rod 44 is fixedly connected to the surface of the outer frame 42. A magnetic suction rod 43 is fixedly connected to the side of the vacuum cleaner 3 near the iron rod 44. The iron rod 44 and the magnetic suction rod 43 are magnetically connected. By setting up the dustproof device 4, dust is blocked, greatly reducing the possibility of dust entering the heat dissipation holes. This helps to maintain the unobstructed heat dissipation holes, ensure the heat dissipation efficiency of the vacuum cleaner, and reduce the internal overheating problem caused by dust clogging the heat dissipation holes.

[0024] Specifically, the iron rod 44 is L-shaped, and a sliding sleeve 47 is fixedly connected to one side of the vacuum cleaner 3. By setting the iron rod 44, it magnetically engages with the magnetic suction rod 43. When the outer frame 42 is rotated to bring the iron rod 44 and the magnetic suction rod 43 closer together, they attract each other and are tightly fixed. This not only ensures that the filter cloth 41 will not shake or shift during use, but also stably performs its dustproof function.

[0025] Specifically, an arc-shaped ring 46 is slidably connected to the inner wall of the sliding sleeve 47, and multiple air vents are opened on the surface of the filter cloth 41. By setting the arc-shaped ring 46, pressing the arc-shaped ring 46 and then releasing it, the pressure spring 48 will generate elastic force due to the loss of restraint, squeezing the arc-shaped ring 46 to collide with the filter cloth 41. This collision action can effectively make the filter cloth 41 vibrate, thereby shaking off the dust attached to the surface of the filter cloth 41 and achieving the purpose of cleaning the filter cloth 41.

[0026] Specifically, a pressure spring 48 is fixedly connected to one side of the arc-shaped ring 46. The side of the pressure spring 48 away from the arc-shaped ring 46 is fixedly connected to the vacuum cleaner 3. By setting the pressure spring 48, when the arc-shaped ring 46 is pressed and then released, the pressure spring 48 loses its restraint, quickly rebounds and generates elastic force. This elastic force is the direct power source for pushing the arc-shaped ring 46 to collide with the filter cloth 41, causing the filter cloth 41 to shake, thereby shaking off the dust attached to the surface.

[0027] Specifically, one side of the machine body 1 is provided with a collecting device 5, the collecting device 5 comprises a lead screw 54, the lead screw 54 is fixedly connected with the dust collector 3, the surface of the lead screw 54 is sleeved with a fixed block 52, and the upper surface of the fixed block 52 is fixedly connected with a box body 51.

[0028] In the embodiment: through the arrangement of the collecting device 5, after the dust on the surface of the filter cloth 41 is shaken off by the arc-shaped ring 46 driven by the pressure spring 48, the box body 51 can effectively receive the dust, prevent the dust from floating or escaping in the equipment, realize the centralized collection of the dust, and maintain the cleanliness of the equipment and the surrounding environment.

[0029] Specifically, the box body 51 is arranged on the lower surface of the arc-shaped ring 46, and one side of the lead screw 54 is provided with a knob 53.

[0030] Specifically, the inner wall of the knob 53 is provided with a thread, the knob 53 is threadedly connected with the lead screw 54, and the knob 53 abuts against the fixed block 52.

[0031] In the embodiment: through the arrangement of the lead screw 54, the lead screw 54 is connected with the box body 51 through the knob 53, stable support and positioning are provided for the box body 51, when the equipment is normally operated, the box body 51 is ensured to be firmly arranged at the specified position for collecting dust, and the box body 51 will not be displaced due to vibration or other external forces, and the collecting device 5 can reliably receive the dust shaken off from the filter cloth 41.

[0032] Working principle: through the arrangement of the dustproof device 4 and the collecting device 5, when in use, the dust is blocked by the filter cloth 41, the situation that the dust enters the heat dissipation hole is reduced, the filter cloth 41 is rotated towards the arc-shaped ring 46, the magnetic iron rod 44 is separated from the magnetic rod 43, then the arc-shaped ring 46 is pressed, the arc-shaped ring 46 is loosened, the pressure spring 48 loses the constraint and generates elastic force to press the arc-shaped ring 46 to collide with the filter cloth 41, dust on the surface of the filter cloth 41 is shaken off, then the dust falls into the box body 51, then the outer frame 42 is rotated to reset, the iron rod 44 is magnetically attracted and fixed with the magnetic rod 43, the knob 53 is rotated to be separated from the lead screw 54, and the box body 51 can be taken down. Through the arrangement of the utility model, the dust is blocked, the possibility that the dust enters the heat dissipation hole is greatly reduced, which helps to maintain the smoothness of the heat dissipation hole and ensure the heat dissipation efficiency of the vacuum cleaner, and reduces the problem of internal overheating caused by dust blocking the heat dissipation hole.
