Description

Technical Field

[0001] This utility model relates to the field of cleaning vacuuming technology, specifically a rapid cleaning vacuuming device. Background Technology

[0002] Cleaning is an indispensable part of property management. The goal of cleaning is to provide customers with a good and comfortable working and living environment, thereby maintaining and enhancing the value of the property. Tools are one of the important factors affecting the efficiency of cleaning work. Choosing the right cleaning tools can improve the efficiency and quality of cleaning work. When cleaning beds, blankets, fabric sofas, curtains, or some hard-to-reach corners, property cleaning vacuum cleaners have unparalleled advantages over traditional cleaning methods.

[0003] Existing vacuum cleaners need to separate the sucked-up dust and debris from the air during use to prevent subsequent air discharge from polluting the surrounding environment. However, after prolonged use, the surface of the filter screen used to separate dust and debris at the exhaust port is easily blocked by debris, causing filter clogging. This prevents subsequent dust from passing through the filter and separating from the debris, resulting in a significant reduction in suction power and thus a decrease in the cleaning effect of dust and debris. Utility Model Content

[0004] The purpose of this invention is to provide a fast cleaning vacuuming device to solve the problem mentioned in the background art that the filter will become clogged after long-term use.

[0005] To achieve the above objectives, this utility model provides the following technical solution, including a three-wheeled vacuum cleaner, on which a vacuum box is installed. An air supply pipe is connected to the bottom of the rear side of the vacuum box. The bottom of the air supply pipe is connected to a suction pipe via a tapering structure. A fan is installed on the top right side of the vacuum box. The vacuum box contains a C-shaped exhaust chamber and a cleaning chamber, which are connected. A filter screen is fixedly connected to the bottom of the C-shaped exhaust chamber. A motor is embedded in the cleaning chamber of the vacuum box. The output shaft of the motor is fixedly connected to a threaded rod. The left side of the threaded rod is movably connected to the inner wall of the cleaning chamber. A movable plate is threadedly connected to the surface of the threaded rod. Two electric telescopic rods are fixedly connected to the bottom of the movable plate. The output shafts of the two electric telescopic rods extend to the C-shaped exhaust chamber and are fixedly connected to a scraper. The scraper contacts the inner wall of the C-shaped exhaust chamber. A sealing structure is installed in the cleaning chamber. A dust collection screen is movably connected to the top of the C-shaped exhaust chamber in the dust collection box. The front side of the dust collection screen extends to the outside of the dust collection box.

[0006] Preferably, the tapered structure includes two tapered tubes, which are respectively connected to the air supply tube and the air inhalation tube, and a throat tube is connected between the two tapered tubes. A spiral plate is fixedly connected to the inner cavity of the throat tube.

[0007] Preferably, the sealing structure includes an electric push rod, the surface of which is embedded inside the cleaning chamber, and the output shaft of the electric push rod is fixedly connected to a baffle, the surface of which is movably connected to the inner wall of the cleaning chamber.

[0008] Preferably, grooves are provided on both the front and rear sides of the cleaning chamber in the dust collection box, and a limiting block is movably connected to the right side of the inner cavity of the groove. The two limiting blocks are fixedly connected to the baffle between each other.

[0009] Preferably, the top of the cleaning chamber in the dust collection box is provided with a T-shaped groove, and a T-shaped block is movably connected to the inner cavity of the T-shaped groove. The bottom of the T-shaped block is fixedly connected to the movable plate.

[0010] Preferably, a limiting plate is fixedly connected to the surface of the air supply pipe, and the left side of the limiting plate is fixedly connected to the three-wheeled vacuum cleaner.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This solution allows the motor output shaft to rotate the threaded rod while cleaning debris from the filter screen surface, indirectly moving the electric telescopic rod. When it reaches the connection between the C-shaped exhaust chamber and the cleaning chamber, it moves the scraper downwards. Subsequently, when the motor output shaft moves the scraper to the cleaning position of the filter screen, the electric telescopic rod moves the scraper upwards to clean the surface of the filter screen, thus solving the problem of filter screen clogging caused by prolonged use.

[0020] Example 1:

[0021] Please see Figure 1-4 This utility model provides a technical solution: a rapid cleaning and vacuuming device, including a three-wheeled vacuum cleaner 1, a vacuum box 2 installed on the three-wheeled vacuum cleaner 1, an air supply pipe 3 connected to the bottom of the rear side of the vacuum box 2, an air intake pipe 4 connected to the bottom of the air supply pipe 3 through a tapering structure, an exhaust fan 5 installed on the top right side of the vacuum box 2, a C-shaped exhaust chamber and a cleaning chamber opened inside the vacuum box 2, the C-shaped exhaust chamber and the cleaning chamber being connected, a filter screen 6 fixedly connected to the bottom of the C-shaped exhaust chamber in the vacuum box 2, and a motor 7 embedded in the cleaning chamber of the vacuum box 2. The output shaft of the machine 7 is fixedly connected to a threaded rod 8. The left side of the threaded rod 8 is movably connected to the inner wall of the cleaning chamber. A movable plate 9 is threadedly connected to the surface of the threaded rod 8. Two electric telescopic rods 10 are fixedly connected to the bottom of the movable plate 9. The output shafts of the two electric telescopic rods 10 extend to the C-shaped exhaust chamber and are fixedly connected to a scraper 11. The scraper 11 contacts the inner wall of the C-shaped exhaust chamber. A sealing structure is installed in the cleaning chamber. A dust collection screen 12 is movably connected to the top of the C-shaped exhaust chamber in the dust collection box 2. The front side of the dust collection screen 12 extends to the outside of the dust collection box 2.

[0022] Analysis of the above content: During use, the operator starts the exhaust fan 5, which draws external air into the suction pipe 4. The air velocity increases through a tapering structure, and then the air enters the dust collection box 2 through the air delivery pipe 3. The air moves within the C-shaped exhaust chamber of the dust collection box 2. At this time, the filter screen 6 intercepts debris and particles in the air, separating them from the dust. The separated dust and air are then filtered through multiple filter plates in the C-shaped exhaust chamber. The dust then enters the dust collection screen 12 (the dust collection screen 12 can be made of a material similar to that of a bag filter), while the air is discharged through the interceptor net installed on the right side of the dust collection screen 12 and then through the exhaust fan 5. When there is a large amount of debris on the filter screen 6, the sealing structure connecting the C-shaped exhaust chamber and the cleaning chamber opens. Then, the output shaft of the motor 7 drives the threaded rod 8 to rotate. During rotation, the threaded rod 8 moves two electric telescopic rods 10 via the movable plate 9. When it reaches the designated position... At the same time, the electric telescopic rod 10 drives the scraper 11 to move downward synchronously through the controller (Note: the circuit of how the two electric telescopic rods 10 drive downward synchronously is very mature in the existing technology and does not need to be described). When the scraper 11 moves to the designated position, the output shaft of the motor 7 drives the scraper 11 to move to the left through the above operation. When the scraper 11 touches the filter screen 6, the electric telescopic rod 10 drives the scraper 11 to move upward. During the upward movement, the scraper 11 cleans the debris on the filter screen 6 (since the size of the debris is larger than the mesh of the filter screen 6, it is not easy to cause the mesh of the filter screen 6 to be blocked after scraping, thus achieving cleaning, and the filter screen 6 can be disassembled for cleaning or replacement). At the same time, the collection groove in the scraper 11 collects the debris that has been cleaned. When the filter screen 6 is cleaned, the scraper 11 re-enters the cleaning chamber and is then sealed by the sealing structure, thus solving the problem that the filter screen will be blocked by long-term use.

[0023] Example 2:

[0024] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the tapered structure includes two tapered tubes 13, which are respectively connected to the air supply tube 3 and the air intake tube 4. The two tapered tubes 13 are connected to a throat tube 14 in the middle, and a spiral plate 15 is fixedly connected to the inner cavity of the throat tube 14.

[0025] Analysis of the above content: When the exhaust fan 5 draws outside air into the air supply pipe 3 through the intake pipe 4, the air enters the trumpet-shaped converging pipe 13. At this time, the air first expands and then contracts in the converging pipe 13. During the contraction process, it enters the throat 14, where the diameter of the throat 14 is small, thereby increasing the air velocity. At the same time, the designed spiral plate 15 causes the air to rotate. Centrifugal force will squeeze the air against the outer wall of the throat 14, resulting in a decrease in pressure in the central area. This causes the air velocity to increase due to the conversion of static pressure energy into kinetic energy (similar to the increased air velocity at the center of a tornado). Then, it expands and contracts again through another converging pipe 13, making it faster for outside air to enter the dust collection box 2. This effectively reduces the resistance in the air duct and increases the intake speed of air and dust.

[0026] Example 3:

[0027] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the sealing structure includes an electric push rod 16, the surface of which is embedded in the interior of the cleaning chamber, and the output shaft of which is fixedly connected to a baffle 17, the surface of which is movably connected to the inner wall of the cleaning chamber.

[0028] Analysis of the above content: After the scraper 11 has cleaned the debris and shavings on the filter screen 6, the electric telescopic rod 10 retracts the scraper 11 into the cleaning chamber. The operator starts the electric push rod 16, and the output shaft of the electric push rod 16 drives the baffle 17 to move. During the movement, the baffle 17 gradually seals the connection between the C-shaped exhaust chamber and the cleaning chamber, preventing the airflow in the C-shaped exhaust chamber from entering the cleaning chamber, thereby completing the seal.

[0029] Example 4:

[0030] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: the front and rear sides of the cleaning chamber in the dust collection box 2 are provided with grooves, and the right side of the inner cavity of the groove is movably connected to a limiting block 18, and the two limiting blocks 18 are fixedly connected to the baffle 17.

[0031] Analysis of the above content: By setting the limiting block 18 to move in the groove, the baffle 17 will not deviate from the moving trajectory during the movement. At the same time, it can prevent the baffle 17 from tilting when it moves to the connection port between the C-shaped exhaust chamber and the cleaning chamber because the bottom is hollow.

[0032] Example 5:

[0033] Please see Figure 1-4The present invention provides a technical solution based on embodiment one: a T-shaped groove 19 is provided at the top of the cleaning chamber in the dust collection box 2, a T-shaped block 20 is movably connected to the inner cavity of the T-shaped groove 19, and the bottom of the T-shaped block 20 is fixedly connected to the movable plate 9.

[0034] Analysis of the above content: By setting the T-slot 19 and the T-block 20 together, the movable plate 9 can be limited to the movement trajectory divided by the T-slot 19 by the T-block 20 during the movement process, so as to prevent misalignment.

[0035] Example 6:

[0036] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: a limiting plate 21 is fixedly connected to the surface of the air pipe 3, and the left side of the limiting plate 21 is fixedly connected to the three-wheeled vacuum cleaner 1.

[0037] Analysis of the above content: By setting the limiting plate 21 to fix and limit the air supply pipe 3, it is prevented that the air supply pipe 3 will fall off due to vibration when the three-wheeled vacuum cleaner 1 moves with the air supply pipe 3.
