Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner technology, specifically a vacuum cleaner with an automatic dust collection function. Background Technology

[0002] A vacuum cleaner is a cleaning appliance that uses an electric motor to generate negative air pressure to suck up dust and debris. The core of a vacuum cleaner is a fan system driven by an electric motor. When the motor rotates at high speed, it quickly expels the air inside the machine, thus creating a momentary low pressure inside the machine. Since the air pressure inside the machine is much lower than the external atmospheric pressure, this pressure difference generates a strong suction force, drawing the outside air, along with dust and debris, into the machine through the suction port.

[0003] For example, a vacuum cleaner bracket with Chinese patent publication number CN218922412U includes: a bracket housing and a hanging bracket. The hanging bracket is folded and connected to the bracket housing. When the hanging bracket is folded, it rests against the bracket housing. When the hanging bracket is unfolded, it is connected to the bracket housing at an angle.

[0004] For example, a vacuum cleaner charging device and vacuum cleaner charging equipment, disclosed in Chinese Patent Publication No. CN208957986U, includes a main unit charging section and a battery compartment. The main unit charging section is provided with a main unit charging port for charging the main unit of the vacuum cleaner. The battery compartment is provided with a receiving cavity for accommodating the battery, and the receiving cavity contains a battery pack that can be detachably installed into the vacuum cleaner. The receiving cavity is provided with a battery charging port for charging the battery pack.

[0005] Currently, the small internal capacity of the storage chamber in most household vacuum cleaners means that the vacuum cleaner needs to frequently empty the impurities inside the storage chamber during operation, and it cannot achieve the function of segmented feeding and quick disassembly of the storage chamber. Therefore, a device is needed to improve this problem. Summary of the Invention

[0006] To address the problems in the prior art, the present invention provides a vacuum cleaner with an automatic dust collection function.

[0011] Specifically, the positioning device includes a guide rod, a base plate, a second rack, and a support vertical plate. The base plate is fixedly installed at the bottom end of the support vertical plate, the guide rod is symmetrically fixedly installed at the top end of the base plate, the second rack is fixedly installed at the rear end of the guide rod, and the guide rod is fixedly installed between the base plate and the support vertical plate.

[0012] Specifically, the extension device includes a limiting sleeve, an extension arm, a transmission gear, and a lower handle. The limiting sleeve is fixedly installed on the top of the rear end of the lower handle, the extension arm is fixedly installed on both sides of the lower handle, and the transmission gear is rotatably installed on the side of the extension arm away from the lower handle.

[0013] Specifically, the lower handle is fixedly installed at the top of the rear end of the air tube, the guide rod is slidably inserted into the rear end of the placement substrate, the movable guide rod is slidably inserted into the top end of the limiting sleeve, the support substrate is rotatably installed at the top front end of the placement substrate, and the first rack and the second rack are respectively engaged with the transmission gear.

[0014] Specifically, four positioning rods are symmetrically fixedly installed at the bottom end of the top cover plate. Threaded holes are opened inside the bottom end of the movable guide rod and at the top of the rear end of the lower handle. The thickness of the second rack and the first rack is 0.5 cm, the thickness of the transmission gear is 1 cm, and round holes are symmetrically opened inside the rear end of the substrate placement plate. The side end of the contact push plate near the positioning rod is inclined at 45°.

[0017] First, this invention allows the accumulation cavity to be quickly installed onto the support substrate by sliding the mounting rod inside. Simultaneously, it communicates with the top of the guide rod through the first interface, facilitating the collection of impurities inside the accumulation cavity. Furthermore, the support substrate can be rotated and adjusted to rotate the accumulation cavity below the top cover plate, so that when the top cover plate moves downward, it can press the accumulation cavity onto the top of the placement substrate, completing the segmented feeding of the accumulation cavity.

[0018] Second, the present invention allows the upper handle to be pulled upwards, which can separate the top cover plate from the accumulation cavity. At the same time, the first rack can drive the second rack to move to the rear end through the transmission gear, so that the guide rod can be pulled out from the inside of the accumulation cavity. Simultaneously, the contact push plate can be moved out from the bottom end of the positioning rod, and the positioning rod can be pulled out from the inside of the collar, releasing the accumulation cavity. Furthermore, when the upper handle moves downwards, the positioning rod at the bottom end of the top cover plate and the positioning rod on the placement base plate can be inserted into the inside of the collar, which can restrict and fix the accumulation cavity again. The upper handle can be restricted and fixed by external bolts through the movable guide rod, thus completing the work of quickly disassembling and assembling the accumulation cavity.

Through the setting of the special-shaped bracket 14, the upper handle 16 can be supported to drive the first rack 13 to move.

[0033] like Figure 4 The support component 3 includes a connecting device 17, a positioning device 18, and an extension device 40. The positioning device 18 is slidably inserted into the rear end of the connecting device 17, and the extension device 40 is fixedly installed on the top of the rear end of the connecting device 17 to support the operation of the positioning device 18.

[0034] like Figure 5 and Figure 6The connecting device 17 includes a placement substrate 19, an air tube 20, a suction head 21, a positioning rod 22, an anti-detachment plate 23, a contact push plate 24, a movable hole 25, a connecting crossbar 26, a second interface 27, and a magnetic suction plate 28. The air tube 20 is fixedly installed at the bottom center of the placement substrate 19, the suction head 21 is installed at the bottom of the air tube 20, the magnetic suction plate 28 is fixedly installed at the top side of the placement substrate 19, the positioning rod 22 is symmetrically slidably inserted into the top of the placement substrate 19, the anti-detachment plate 23 is fixedly installed at the bottom of the outer ring of the positioning rod 22, the connecting crossbar 26 is symmetrically slidably inserted into the inner two sides of the placement substrate 19, the contact push plate 24 is fixedly installed at the side of the connecting crossbar 26, and the movable hole 25 is symmetrically opened on the inner two sides of the placement substrate 19. A round hole is opened in the rear end of the placement substrate 19 to facilitate the sliding of the guide rod 29 inside the placement substrate 19.

[0035] like Figure 7 The positioning device 18 includes a guide rod 29, a guide rod 30, a mating base plate 31, a second rack 32, and a supporting vertical plate 33. The mating base plate 31 is fixedly installed at the bottom end of the supporting vertical plate 33. The guide rod 29 is symmetrically fixedly installed at the top end of the mating base plate 31. The second rack 32 is fixedly installed at the rear end of the guide rod 29. The guide rod 30 is fixedly installed between the mating base plate 31 and the supporting vertical plate 33. The guide rod 29 slides inside the placement base plate 19, so that the supporting vertical plate 33 and the mating base plate 31 can be supported to move in a straight line.

[0036] like Figure 8 The extension device 40 includes a limiting sleeve 34, an extension arm 35, a transmission gear 36, and a lower handle 37. The limiting sleeve 34 is fixedly installed on the top of the rear end of the lower handle 37, the extension arm 35 is fixedly installed on both sides of the lower handle 37, and the transmission gear 36 is rotatably installed on the side end of the extension arm 35 away from the lower handle 37. The limiting sleeve 34 allows the movable guide rod 15 to move up and down in a straight line.

[0037] The lower handle 37 is fixedly installed at the top rear end of the air tube 20. The guide rod 29 is slidably inserted into the rear end of the placement substrate 19. The movable guide rod 15 is slidably inserted into the top end of the limiting sleeve 34. The support substrate 5 is rotatably installed at the top front end of the placement substrate 19. The first rack 13 and the second rack 32 respectively mesh with the transmission gear 36. Four positioning rods 22 are symmetrically fixedly installed at the bottom end of the top cover plate 12. Threaded holes are opened in the bottom end of the movable guide rod 15 and at the top rear end of the lower handle 37. The thickness of the second rack 32 and the first rack 13 is 0.5 cm, and the thickness of the transmission gear 36 is 1 cm. Circular holes are symmetrically opened in the rear end of the placement substrate 19. The contact push plate 24 is close to... The side end of the positioning rod 22 is inclined at 45°, and the bottom end of the positioning rod 22 is arc-shaped. The bottom end of the movable guide rod 15 is fixedly installed with an anti-detachment plate. Plastic gaskets are installed on the rear end of the second interface 27 and the side end of the first interface 4 away from the accumulation cavity 9. A sealing ring is fixedly installed on the bottom end of the top cover plate 12. The end of the connecting crossbar 26 away from the contact push plate 24 is connected to the end of the guide rod 29 away from the second rack 32. The top and bottom ends of the guide rod 30 are horizontally aligned with the first interface 4 and the second interface 27, respectively. A sliding hole is opened inside the limiting sleeve 34. A guide groove that matches the connecting crossbar 26 is opened on the side end of the movable hole 25. The top end of the magnetic suction plate 28 is flush with the bottom end of the iron plate 7.

[0038] The working principle is as follows: When in use, the fan 10 can be turned on. The blades installed at the bottom of the fan 10 create negative pressure inside the accumulation chamber 9 when they rotate at high speed. This allows impurities on the ground to be absorbed through the air pipe 20 and suction head 21, causing the impurities to accumulate inside the accumulation chamber 9, thus completing the dust collection work. When too many impurities accumulate inside one accumulation chamber 9, the fan 10 can be stopped. Then, the bolt installed inside the rear end of the lower handle 37 can be unscrewed and removed from the lower handle 37 and the movable guide rod 15. The upper handle 16 can then be pulled upwards, causing the top cover plate 12 to detach from the top of the accumulation chamber 9 until the filter cartridge 11 moves above the accumulation chamber 9. Simultaneously, the movable guide rod 15 slides into the... The limiting sleeve 34 ensures that the fan 10 moves upward in a straight line. When the movable guide rod 15 moves upward, it drives the first rack 13 to rotate the transmission gear 36. When the transmission gear 36 rotates, it drives the second rack 32 to move away from the placement substrate 19, allowing the guide rod 29 to pull the guide rod 30 out from the inside of the second interface 27 and the first interface 4. This disconnects the accumulation cavity 9 from the air pipe 20. At the same time, when the guide rod 29 moves, it can also drive the movable hole 25 to move synchronously through the connecting crossbar 26, allowing the contact push plate 24 to move to a position that is misaligned with the bottom of the positioning rod 22. At this time, the positioning rod 22 will slide downward and fall into the interior of the movable hole 25, allowing the positioning rod 22 to be pulled out from the bottom of the side of the accumulation cavity 9. The bottom of the accumulation cavity 9 can be unlocked by removing the collar 8. When the positioning rod 22 is moved downwards to its limit position, its top end is flush with the top end of the placement substrate 19, preventing it from falling off. After the accumulation cavity 9 is released, the user can rotate it. The support substrate 5 is rotated and mounted on the top front end of the placement substrate 19, supporting the rotation adjustment of the accumulation cavity 9. When the empty accumulation cavity 9 is rotated to be perpendicularly aligned with the filter cartridge 11, the upper handle 16 can be moved downwards until the top cover plate 12 is moved to the top of the accumulation cavity 9. At this point, the positioning rod 22 at the bottom of the top cover plate 12 can be inserted into the collar 8 at the top side of the accumulation cavity 9. Simultaneously, when the upper handle 16 is moved downwards, it can... The first rack 13 moves downward along the surface of the transmission gear 36, causing the second rack 32 to move forward. This supports the vertical plate 33 and the mating base plate 31, allowing the guide rod 30 to move and insert into the second interface 27 and the first interface 4. This facilitates the guide rod 30 reconnecting with the accumulation cavity 9. When the guide rod 29 resets, it moves the movable hole 25 forward. The contact push plate 24 is inclined at 45° to the side surface near the positioning rod 22, improving the smoothness of contact between the contact push plate 24 and the positioning rod 22. When the contact push plate 24 moves forward, it presses the positioning rod 22 upward, allowing the positioning rod 22 to be inserted into the collar 8 at the bottom side of the accumulation cavity 9, thus fixing the bottom of the accumulation cavity 9.To complete the quick assembly and disassembly of the accumulation chamber 9, during use, when the guide rod 30 moves to contact the second interface 27 and the first interface 4, plastic gaskets are installed on the sides of both the second interface 27 and the first interface 4 to prevent air leakage at the connection between the guide rod 30 and the accumulation chamber 9. Simultaneously, when the top cover plate 12 moves downward to its extreme position, the sealing ring at the bottom of the top cover plate 12 connects with the accumulation chamber 9, preventing air leakage at the connection area between the accumulation chamber 9 and the top cover plate 12. When the accumulation chamber 9 rotates... The iron plate 7 can be rotated to adhere to the magnetic plate 28, facilitating the alignment of the storage cavity 9 with the first interface 4 and the guide rod 30. Simultaneously, an anti-detachment plate is installed at the bottom of the movable guide rod 15 to prevent it from detaching from the limiting sleeve 34 when the upper handle 16 moves upward. The anti-detachment plate 23 prevents the positioning rod 22 from detaching from the placement substrate 19. The second rack 32 is offset from the first rack 13 to prevent interference when the first rack 13 moves up and down. This completes the operation.
