Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vacuum cleaners, and in particular to an automatic dust removal structure. Background Technology
[0002] After using the vacuum cleaner, dust is collected inside the dust cup. Meanwhile, due to the filter cartridge's filtration of the airflow, dust particles adhere to its surface. Therefore, to achieve thorough cleaning of the vacuum cleaner after use, it is necessary to empty the dust cup and clean the filter cartridge surface.
[0003] In the prior art, the cleaning of the dust cup inside the vacuum cleaner has the following problems: (1) The cleaning of the dust cup and the filter cartridge in the vacuum cleaner are independent of each other, resulting in low cleaning efficiency of the vacuum cleaner; (2) At present, the cleaning of the dust cup of the vacuum cleaner faces the problem of dirty hands, which is not conducive to hygiene; (3) The current cleaning method is not thorough enough, and a lot of dust is often adsorbed on the inner wall of the dust cup. Utility Model Content
[0004] The present invention aims to overcome the shortcomings of low cleaning efficiency in existing vacuum cleaners by providing an automatic dust removal structure that improves cleaning efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic dust removal structure includes a body and a dust cup cover. The body has a dust outlet at one end, and a filter cartridge is detachably fixed to the dust outlet. One end of the dust cup cover is fitted onto the outer wall of the body and is slidably and sealingly connected to the body along its height. The filter cartridge is located inside the dust cup cover. The interior of the body connects to the interior of the dust cup cover via the dust outlet and the filter cartridge. The other end of the dust cup cover has a cleaning port. A dust removal ring is located inside the dust cup cover. The inner circumferential surface of the dust removal ring contacts the surface of the filter cartridge, and the outer circumferential surface of the dust removal ring contacts the side wall of the dust cup cover. A transmission mechanism is located inside the dust cup cover. The dust cup cover is connected to the dust removal ring via the transmission mechanism. Under the forward drive of the dust cup cover, the dust removal ring slides in the reverse direction within the dust cup cover via the power transmission of the transmission mechanism.
[0006] The end of the machine body is provided with a dust outlet, and a filter cartridge is detachably fixed at the dust outlet. One end of the dust cup cover is sleeved on the outer wall of the machine body and is slidably connected to the machine body along the height direction of the dust cup cover. The filter cartridge is located inside the dust cup cover. The interior of the machine body is connected to the interior of the dust cup cover after passing through the dust outlet and the filter cartridge in sequence. The other end of the dust cup cover is provided with a cleaning port. A dust removal ring is provided inside the dust cup cover. The inner circumferential surface of the dust removal ring contacts the surface of the filter cartridge, and the outer circumferential surface of the dust removal ring contacts the side wall of the dust cup cover. A transmission mechanism is provided inside the dust cup cover. The dust cup cover is connected to the dust removal ring through the transmission mechanism. Under the forward drive of the dust cup cover, the dust removal ring is slidably connected to the dust cup cover in the reverse direction through the power transmission of the transmission mechanism. The machine has a built-in motor to create negative pressure. Dust drawn in by this negative pressure enters the filter cartridge through the dust outlet, is filtered, and then collected inside the dust cup hood. The machine body is existing technology, so its internal structure will not be described in detail here. When cleaning the dust cup hood, the operator simply pushes the dust cup hood downwards towards the machine body, creating relative movement. Through the power transmission mechanism, the dust-removing ring slides upwards in the opposite direction within the dust cup hood. During this sliding process, the dust-removing ring simultaneously pushes dust from the filter cartridge surface, the inside of the dust cup hood, and the inner sidewall of the dust cup hood upwards via its inner and outer circumferential surfaces, bringing it to the cleaning port. This ensures thorough cleaning and facilitates dust removal. The cleaning of the dust cup hood and filter cartridge can be performed simultaneously, improving cleaning efficiency. Furthermore, the operator only needs to hold the outer wall of the dust cup hood to complete the entire cleaning process, minimizing hand dirt. The cleaning port of the dust cup hood is usually closed by a lid when the machine is in operation.
[0007] Preferably, the transmission mechanism includes two rigid chains, which are symmetrically distributed in a U-shape around the filter cartridge and located inside the dust cup hood. Two steering rings, each matching one of the two rigid chains, are rotatably connected to the end of the machine body. One end of each rigid chain is detachably fixed to the inner wall of the dust cup hood, and the other end, after passing around the steering rings, is detachably fixed to the bottom of the dust-collecting ring. The top of the dust-collecting ring serves as the dust-collecting surface. Utilizing the principle that rigid chains can only bend in one direction, the operator pushes the dust cup hood downwards, converting the downward linear motion of the dust cup hood relative to the machine body into an upward linear motion of the dust-collecting ring. This allows the dust-collecting ring to simultaneously drive dust and debris from the filter cartridge surface, the inside of the dust cup hood, and the inner wall of the dust cup hood through the dust-collecting surface to the cleaning port, thus improving the cleaning effect.
[0008] Preferably, one end of the filter cartridge is connected to the dust outlet, while the other end is closed. This improves both the filtration efficiency and the ease of cleaning the dust.
[0009] Preferably, the dust cup cover has channels on both the left and right inner sidewalls that match the corresponding rigid chains. One end of each channel is close to the machine body and open outwards, while the other end is far from the machine body and closed. One end of the rigid chain is detachably fixed inside the channel, and the other end passes through the open end of the channel, passes around the steering ring, and is detachably fixed to the bottom of the dust removal ring. The connection method of the two ends of the rigid chain is existing technology and will not be described in detail here. Placing one end of the rigid chain inside the channel helps to improve the cleaning effect of the dust removal ring on the dust inside the dust cup cover and on the sidewalls of the dust cup cover.
[0010] The beneficial effects of this utility model are: 1. The dust removal ring pushes the dust and debris on the filter cartridge surface, the inside of the dust cup cover, and the inner side wall of the dust cup cover upwards through its inner and outer circumferential surfaces, driving them to the cleaning port. This ensures thorough cleaning and facilitates the removal of dust and debris. During the above process, the cleaning of the dust cup cover and the filter cartridge can be carried out simultaneously, thereby improving cleaning efficiency. 2. The operator only needs to hold the outer wall of the dust cup cover to complete the entire cleaning process, which does not easily get their hands dirty. Attached Figure Description

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In the embodiments described, an automatic dust removal structure includes a body 1 and a dust cup cover 2. The end of the body 1 is provided with a dust outlet 3, and a filter cartridge 4 is detachably fixed at the dust outlet 3. The dust cup cover 2 is characterized in that one end is sleeved on the outer wall of the body 1 and is slidably connected to the body 1 along the height direction of the dust cup cover 2. The filter cartridge 4 is located inside the dust cup cover 2. The interior of the body 1 is connected to the interior of the dust cup cover 2 through the dust outlet 3 and the filter cartridge 4 in sequence. The other end of the dust cup cover 2 is provided with a cleaning port 5. A dust removal ring 6 is provided inside the dust cup cover 2. The inner circumferential surface of the dust removal ring 6 is in contact with the surface of the filter cartridge 4, and the outer circumferential surface of the dust removal ring 6 is in contact with the side wall of the dust cup cover 2. A transmission mechanism 7 is provided inside the dust cup cover 2. The dust cup cover 2 is connected to the dust removal ring 6 through the transmission mechanism 7. Under the forward drive of the dust cup cover 2, the dust removal ring 6 is slidably connected to the dust cup cover 2 in the reverse direction through the power transmission of the transmission mechanism 7.
[0018] like Figure 3 , Figure 4 and Figure 5 As shown, the transmission mechanism 7 includes two rigid chains 8, which are symmetrically distributed in a U-shape around the filter cartridge 4 inside the dust cup hood 2. Two steering rings 9, each matching one of the two rigid chains 8, are rotatably connected to the end of the body 1. One end of each rigid chain 8 is detachably and fixedly connected to the inner wall of the dust cup hood 2, and the other end of each rigid chain 8 is detachably and fixedly connected to the bottom of the dust collection ring 6 after passing around the steering rings 9. The top of the dust collection ring 6 is the dust collection surface 10. One end of the filter cartridge 4 is connected to the dust outlet 3, and the other end of the filter cartridge 4 is closed.
[0019] The dust cup cover 2 has channels 11 on its left and right inner walls that match the corresponding rigid chains 8. One end of the channel 11 is close to the body 1 and is open to the outside, while the other end of the channel 11 is far away from the body 1 and is closed. One end of the rigid chain 8 is detachably fixed inside the channel 11, and the other end of the rigid chain 8 passes through the open end of the channel 11 and passes around the deflector ring 9 and is detachably fixed to the bottom of the dust removal ring 6.
[0020] The machine body 1 draws in dust and debris through negative pressure, which then enters the filter cartridge 4 through the dust outlet 3. After being filtered by the filter cartridge 4, the dust is collected inside the dust cup hood 2. The machine body 1 is existing technology, so its internal structure will not be described in detail here. When it is necessary to clean the dust and debris inside the dust cup hood 2, the operator only needs to push the dust cup hood 2 downward toward the machine body 1, so that it moves relative to the machine body 1. Utilizing the principle that the rigid chain 8 can only bend in one direction, the operator pushes the dust cup hood 2 downward, which transforms the downward linear motion of the dust cup hood 2 relative to the machine body 1 into the upward reverse linear motion of the dust removal ring 6. As the dust removal ring 6 slides upward, it simultaneously pushes the dust and debris on the surface of the filter cartridge 4, the inside of the dust cup cover 2, and the inner sidewall of the dust cup cover 2 upward through its inner and outer circumferential surfaces, driving them to the cleaning port 5. This ensures thorough cleaning and facilitates the removal of dust and debris. During the above process, the cleaning of the dust cup cover 2 and the filter cartridge 4 can be carried out simultaneously, thereby improving cleaning efficiency. At the same time, the operator only needs to hold the outer sidewall of the dust cup cover 2 to complete the entire cleaning process, which does not easily get their hands dirty.
[0021] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
