Description

[Technical Field]

[0001] This invention relates to the field of vacuum cleaner technology, and more particularly to a cleaning device with a compact dust-scraping structure. [Background Technology]

[0002] Existing cleaning equipment, especially handheld vacuum cleaners, typically includes a main body, a detachable cyclone separator mounted on the main body, a motor within the main body to generate negative pressure, and a power supply system. The power supply system powers the motor to create negative pressure. After dust and air are drawn in, they pass through the cyclone separator to separate the dust and air. Dust remains inside the cyclone separator, while clean air is discharged. The motor and cyclone separator are usually connected to achieve airflow. Existing cyclone separators include a cup body and a separator housed within the cup body. This separator uses a filter structure at least in the first stage of filtration, and can also incorporate a second-stage cyclone or conical second-stage separation structure within the filter to achieve multi-stage filtration. Cyclone separation works by rotating the airflow around the separator after dust enters it, while simultaneously passing through the filter screen for primary filtration. Most dust and hair are filtered out in this primary filter, and the dust falls into and is stored in the cup. To empty the dust, the cyclone separator must be removed from the main body, or the bottom of the cup must be opened. It is worth noting that a large amount of dust and hair usually adheres to or tangles around the outer edge of the primary filter screen. Users have to manually remove the dirt adhering to the outer edge of the primary filter screen when emptying the dust, resulting in a very poor product experience and greatly reducing users' willingness to use handheld vacuum cleaners.

[0003] The closest existing technology can be found in Chinese Utility Model Patent CN210871286U, which discloses a cyclone filter for a handheld vacuum cleaner. Its cyclone separation structure includes a dust cup and a separator disposed in the dust cup. The primary separator of the separator is a filter screen separator. The filter screen needs to be manually cleaned when emptying the dust.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. [Summary of the Invention]

[0005] The purpose of this invention is to provide a cleaning device with a highly efficient and convenient dust removal structure.

[0006] The objective of this invention is achieved through the following technical solution: a cleaning device with a compact dust-scraping structure, comprising: a body, a motor disposed within the body, and a cyclone separator connected to the body. The body includes a main body and a pressing part sleeved within the main body and extending rearward beyond the main body. One end of the pressing part is provided with a connecting rod extending into the body. The cyclone separator is provided with a primary separator and a scraping part located on the outer surface of the primary separator. The scraping part is provided with a driving rod extending into the main body. The pressing part can be stretched rearward to connect with the driving rod and can drive the driving rod to move forward.

[0028] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Please see Figures 1 to 8 As shown, the present invention provides an efficient and simple dust-scraping structure and cleaning device. Specifically, the cleaning device can be one of a handheld vacuum cleaner, a canister vacuum cleaner, or a commercial vacuum cleaner, and can be further applied to a sweeping robot.

[0030] In the following detailed description, only handheld vacuum cleaners in cleaning equipment will be used as an example.

[0031] A handheld vacuum cleaner 100 includes a body 1, a handle 2 connected to the body 1, a cyclone separator 3 disposed on the body 1, a motor 4 disposed inside the body 1 for generating negative pressure, and a power supply system 5. In this solution, the power supply system is a battery pack.

[0032] The cyclone separator 3 includes a cup body 31 and a separation device 32 disposed within the cup body 31. The cup body 31 is generally cylindrical and includes a surrounding side wall 311 and a bottom wall 312 disposed at the bottom of the side wall 311, which can open or seal the bottom of the side wall 311. An axis X extending through the bottom wall 312 is disposed at the center of the cup body 31. Depending on different installation requirements, the cyclone separator 32 can be installed in the following ways: 1. The separation device 32 and the cup body 31 are detachably installed together and then detachably mounted on the body 1; 2. The separation device 32 is detachably or non-detachably fixedly mounted to the body 1, and the cup body 31 is also detachably fixedly mounted to the body 1; 3. The separation device 32 and the cup body 31 are both non-detachably mounted on the body 1, and when the cyclone separator 3 is emptying ash, the ash is emptied only by opening the bottom wall 312 of the cup body 31. Depending on the needs of the cleaning equipment, a suitable cyclone separator 3 installation method can be selected, which will not be elaborated here.

[0033] The body 1 includes a main body 11 for docking with the cyclone separator 3, an air intake channel 12 extending forward from the bottom of the main body 11, and a pressing part 13 extending backward from the main body 11 towards the cyclone separator 3. The air intake channel 12 is used to support the cyclone separator 3. The air intake channel 12 is provided with an airflow inlet and is connected to the airflow inlet of the cyclone separator 3. When the handheld vacuum cleaner 100 is started, dust is drawn in from the inlet of the air intake channel 12 and flows into the cyclone separator 3 for dust separation. The cyclone separator 3 is supported on the air intake channel 12 and is docked and connected to the main body 11 from front to back. In other embodiments, the cyclone separator 3 can adopt a central air intake method, with the dust inlet set on the bottom wall 312 of the cup body 31 of the cyclone separator 3. With this setting, it is not necessary to set up an air intake channel 12 to support the cyclone separator 3. Instead, the cyclone separator 3 is connected to the main body 11 by a fixed connection, but the cyclone separator 3 and the main body 11 are still connected from front to back. This will not be described in detail here.

[0034] The pressing part 13 is sleeved with the main body 11. The outer diameter of the pressing part 13 is smaller than the inner diameter of the main body 11. The pressing part 13 can slide and push back and forth along the inner side of the main body 11. The pressing part 13 is sleeved on the rear end of the main body 11 and extends rearward beyond the rear end of the main body 11. The outer contour of the pressing part 13 is roughly cylindrical. The pressing part 13 includes a rear end 131 extending outward from the rear end of the main body 11 and a front end 132 located inside the main body. The two sides of the rear end 131 are provided with gripping grooves 133 for the user to hold. The front end of the pressing part 13 is engaged with the inner side of the rear end of the main body 11 to prevent the pressing part 13 from detaching from the main body 11. Both the pressing part 13 and the inner side of the main body 11 are hollow. A visual electronic display screen can be provided on the rear wall of the pressing part 13. The visual electronic display screen can display information such as the current working status of the handheld vacuum cleaner.

[0035] The separation device 32 includes a primary separator 33 and a secondary separator 34 disposed inside the primary separator 33. The primary separator 33 includes an annular body 331 and a secondary dust storage part 332 that extends downward from the lower end of the body 331. A primary cyclone space for cyclone circulation is formed between the primary separator 33 and the cup body 31. Dust is drawn into the primary cyclone space from the airflow inlet of the cup body 31. The dust rotates around the primary separator 33 in the primary cyclone space. The body 331 of the primary separator 33 is a perforated filter screen 333 arranged around it. Large dust particles in the dust rotate around the primary separator 33 and are thrown into the lower end of the cup body 31 due to centrifugal force. Other dust enters the interior of the body 331 of the primary separator 33 from the perforated body 331.

[0036] The secondary ash storage section 332 narrows inward from the lower end of the filter screen 333 and then extends vertically downward to form a structure combining an inverted cone and a cylinder. When the bottom wall is closed, the cylindrical bottom of the secondary ash storage section 332 extends downward and abuts against the bottom wall 312 of the cup body 31. The secondary separator 34 is disposed inside the body part 331 of the primary separator 33 and is surrounded by the body part 331. The secondary separator 34 includes a cone that is axially arranged around the axis of the cup body 31.

[0037] Among them, a scraping member 35 is provided on the outer surface of the separator 32. The scraping member 35 includes a scraping part 351 surrounding the filter screen 333 of the primary separator 33 and a drive rod 352 connected to the scraping part 351 and extending rearward into the main body 11. The drive rod 352 is provided with a through-hole 3521.

[0038] The front end of the pressing part 13 is provided with a connecting rod 14 extending into the main body 11. The connecting rod 14 is provided with a protruding buckle 141 that can extend and engage with the communicating hole 3521. When the pressing part 13 is pulled backward out of the main body 11, the connecting rod 14 moves backward relative to the driving rod 352 until the protruding buckle of the connecting rod 14 is received in the communicating hole 3521. Then the pressing part 13 presses forward again, and the connecting rod 14 drives the driving rod 352 to move forward. The driving rod 352 is connected to a ring surrounding the first-stage separation. The scraping part 351 on the outer periphery of the device 33 is made of flexible material and can abut against the outer wall of the primary separator 33 and scrape the outer surface of the primary separator 33 back and forth along the X-axis. When the pressing part 31 is pushed to the front end, the boss 15 provided in the main body 11 presses the buckle 141 out of the connecting hole 3521. In this way, the connecting rod 14 is disengaged from the driving rod 352. A spring (not shown) is provided on the driving rod 352 to reset the driving rod 352 backward.

[0039] In the initial state, the scraper 351 is located at the root end of the primary separator 33 to avoid adverse effects on the separation effect of the cyclone separator 3. When the pressing part 13 is stretched and pressed again, the connecting rod 14 drives the scraper 35 to move towards the bottom 312 of the cup body 31. At the same time, the scraper 35 scrapes the outer surface of the primary cyclone separator 33, cleaning the dust and hair adsorbed or wrapped on the surface of the primary cyclone separator 33 and removing them from the outer surface of the primary cyclone separator 33. These dirty objects fall into the cup body 31 for collection. In this way, the user can avoid manually cleaning the primary cyclone separator 33.

[0040] The rear end face of the main body 1 is provided with a pressable unlock button 16. The unlock button 16 is connected to the bottom wall of the cup body 31 via a connecting rod. When the user presses the unlock button 16, the latch on the bottom wall of the cup body 31 is unlocked and pops open, allowing the bottom wall 312 of the cup body 31 to be opened for emptying ash. In a further embodiment, the unlock button 16 can be connected to the pressing part 13. When the unlock button 16 is not pressed to unlock, the pressing part 13 cannot be stretched out of the main body 11.

[0041] The handle 2 is supported below the body 1, and the power supply system 4 is located at the bottom of the handle 2. That is, the handle 2 is located between the body 1 and the power supply system 4. The pressing part 13 extends backward but does not exceed the rear end of the power supply system 4. When the main body 11 is stretched out, the rear end of the pressing part 13 extends backward beyond the rear end of the power supply system 4.

[0042] In this way, the overall length of the handheld vacuum cleaner 100 can be reduced to a smaller size, without the length being increased due to the addition of a dust scraping mechanism.

[0043] According to the structural scheme of the present invention, the pressing part 13 can be configured to be stretchable even when the handheld vacuum cleaner 100 is in use. During the use of the handheld vacuum cleaner 100, if the primary separator 33 is blocked by dust or hair, the pressing part 13 can be pressed at any time to drive the scraping part 15 to clean the outer surface of the primary separator 33. There is no need to remove the cup body 31 for manual cleaning, which is cleaner, more hygienic and convenient.

[0044] In this invention patent, the present invention is a cleaning solution that can be used to clean the first stage separator 33 of a cyclone separator in a cleaning appliance. Its application scope is not limited to any form of cleaning appliance. This structure can be used in handheld, gun-type, upright and any other form of cleaning appliance, which will not be described in detail in this patent.

[0045] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention, and those skilled in the art can easily implement other modifications. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein. The above is merely one specific embodiment of the present invention, and any improvements made based on the inventive concept are considered to be within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
