A vehicle-mounted dust collection device

Abstract

This utility model discloses a vehicle vacuum cleaner. A fan operates, drawing air from the vacuum chamber through ventilation holes, creating negative pressure inside. External air is then drawn in through the suction pipe, which is aimed at the area to be cleaned. Dust or moisture enters the air intake chamber along with the air through the suction pipe. Under the action of the filter assembly, large dust particles are intercepted and fall into the dust collection bin, while fine dust particles and moisture pass through the filter assembly into the air outlet chamber and are discharged through the ventilation holes. During the cleaning process, most of the water and dust mixture falls directly into the dust collection bin under gravity, preventing clogging of the filter assembly and ensuring effective vacuuming. Furthermore, dust and other debris do not accumulate in the air intake chamber, and the unobstructed airflow between the fan and the suction pipe further guarantees efficient vacuuming.

Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, specifically to a vehicle vacuum cleaner. Background Technology

[0002] Car vacuum cleaners are often used when cleaning a vehicle. Existing car vacuum cleaners have an air inlet and outlet on the body, a fan assembly inside the outlet, a dust filter between the fan assembly and the inlet, and a suction pipe or nozzle outside the inlet. When the fan assembly operates, a negative pressure is created inside the machine, forcing air in through the inlet, thus drawing dust and debris into the machine. The filter then traps the dust and debris in the cavity between the filter and the inlet. However, during car cleaning, liquids such as water may be accidentally sucked in and mix with the dust, creating a water-dust mixture. This mixture easily clogs the filter, quickly reducing suction effectiveness. Furthermore, the dust and debris trapped in the cavity between the filter and the inlet easily fills up, requiring frequent cleaning; otherwise, the accumulated dust and debris will also reduce suction efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a car vacuum cleaner that can solve the problem that the vacuuming effect of existing car vacuum cleaners is easily reduced during the car cleaning process.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A vehicle vacuum cleaner is provided, including a vacuum chamber, a fan, a dust collection bin, and a filter assembly. The dust collection bin and the filter assembly are both located inside the vacuum chamber. The filter assembly is positioned above the dust collection bin with a gap. An air inlet chamber is formed between the filter assembly and the dust collection bin. An air outlet chamber is formed between the filter assembly and the inner top surface of the vacuum chamber. The vacuum chamber is provided with a suction pipe and a ventilation hole. The suction pipe communicates with the air inlet chamber, and the ventilation hole communicates with the air outlet chamber. The fan is located outside the ventilation hole. The filter assembly is used to filter the gas entering the air outlet chamber from the air inlet chamber.

[0005] As a further improvement to the above technical solution, the filter assembly includes a bracket, a first filter element, and a second filter element. The bracket is installed inside the dust collection box, and the first filter element and the second filter element are stacked sequentially on the bracket from top to bottom. The filtration accuracy of the first filter element is greater than that of the second filter element.

[0006] As a further improvement to the above technical solution, the first filter element includes a first filter screen and a second filter screen, and the second filter element includes a third filter screen and a fourth filter screen. The first filter screen, the second filter screen, the third filter screen and the fourth filter screen are arranged sequentially from top to bottom, and their mesh size increases sequentially from top to bottom.

[0007] As a further improvement to the above technical solution, the inner wall of the dust collection box is provided with two oppositely arranged snap-fit ​​parts, and the edge of the bracket is snapped into both of the snap-fit ​​parts.

[0008] As a further improvement to the above technical solution, the snap-fit ​​part includes two snap-fit ​​strips arranged with an upper and lower gap, and a snap-fit ​​groove is formed between the two snap-fit ​​strips. The edge of the bracket snaps into the snap-fit ​​groove.

[0009] As a further improvement to the above technical solution, the top of the dust collection box is provided with a fan chamber and an air outlet channel. The ventilation hole connects the fan chamber and the air outlet channel. One end of the air outlet channel is connected to the fan chamber, and the other end extends to the side wall of the dust collection box, forming an air outlet on the side wall of the dust collection box. The fan is connected to the fan chamber through a first sealing ring, and the fan is covered with a cover plate. The cover plate is connected to the fan through a second sealing ring.

[0010] As a further improvement to the above technical solution, the lower surface of the cover plate is provided with two limiting strips, which respectively abut against the two inner walls of the air outlet channel.

[0011] As a further improvement to the above technical solution, the dust collection box is provided with an air inlet, which is connected to the air inlet cavity; a connector is provided at the air inlet, and a connecting pipe is provided on the connector, with both ends of the connecting pipe connected to the air inlet and the dust collection pipe, respectively.

[0012] As a further improvement to the above technical solution, the vacuum cleaner box includes a door and a box body with an opening on one side.

[0013] As a further improvement to the above technical solution, a door sealing ring is provided on the opening edge of the box body, and the box door is connected to the opening of the box body through the door sealing ring.

[0014] The beneficial effects of this invention are as follows: When the fan operates, it draws air out of the dust collection box through the ventilation holes, creating negative pressure inside the dust collection box. External air is then drawn in through the suction pipe, which is aimed at the area to be cleaned. Dust or moisture can enter the air inlet chamber along with the air through the suction pipe. Under the action of the filter components, large dust particles are intercepted and fall into the dust collection bin, while fine dust particles and moisture pass through the filter components with the air and enter the air outlet chamber, and are discharged outside the box through the ventilation holes. Less debris falls into the dust collection bin, making it less likely to fill up and reducing the frequency of cleaning, thus facilitating use. During the cleaning process, most of the water and dust mixture falls directly into the dust collection bin under gravity, preventing it from clogging the filter components and ensuring the dust collection effect. Furthermore, dust and other debris do not accumulate in the air inlet chamber, and the airflow path between the fan and the suction pipe is unobstructed, further ensuring the dust collection effect.

The various technical features in this utility model can be combined interactively without contradicting each other.

[0028] Please see Figure 1-8 The preferred embodiment of this utility model provides a vehicle vacuum cleaner, including a vacuum chamber 1, a fan 2, a dust collection bin 3, and a filter assembly 4. The dust collection bin 3 and the filter assembly 4 are both located inside the vacuum chamber 1. The fan 2 is used to provide suction so that air is drawn into the vacuum chamber 1. Under the action of the filter assembly 4, dust and other debris fall into the dust collection bin 3, and the filtered air is discharged from the vacuum chamber 1.

[0029] Specifically, the filter assembly 4 is positioned above the dust collection bin 3, forming an air inlet chamber 41 between the filter assembly 4 and the dust collection bin 3, and an air outlet chamber 42 between the filter assembly 4 and the inner top surface of the dust collection box 1. The dust collection box 1 is equipped with a suction pipe 11 and a ventilation hole 12. The suction pipe 11 is connected to the air inlet chamber 41, and the ventilation hole 12 is connected to the air outlet chamber 42. The fan 2 is located outside the ventilation hole 12. The filter assembly 4 is used to filter the gas entering the air outlet chamber 42 from the air inlet chamber 41. When the blower 2 operates, it draws air from the dust collection box 1 through the ventilation hole 12, creating a negative pressure inside the dust collection box 1. External air is then drawn in through the suction pipe 11, which is aimed at the area to be cleaned. Dust or moisture can enter the air intake chamber 41 along with the air through the suction pipe 11. Under the action of the filter assembly 4, large dust particles are intercepted and fall into the dust collection bin 3, while fine dust particles and moisture pass through the filter assembly 4 into the air outlet chamber 42 and are discharged outside the vehicle through the ventilation hole 12. Less debris falls into the dust collection bin 3, making it less prone to filling and reducing the frequency of cleaning, thus facilitating use. During the cleaning process, most of the water and dust mixture falls directly into the dust collection bin 3 under gravity, preventing it from clogging the filter assembly 4 and ensuring effective dust collection. Furthermore, dust and other debris do not accumulate in the air intake chamber 41, and the unobstructed airflow between the blower 2 and the suction pipe 11 further guarantees effective dust collection.

[0030] The filter assembly 4 includes a support 43, a first filter element 44, and a second filter element 45. The support 43 is installed inside the dust collection box 1. The first filter element 44 and the second filter element 45 are stacked sequentially on the support 43 from top to bottom, and the filtration precision of the first filter element 44 is greater than that of the second filter element 45. This achieves graded processing. The second filter element 45 is used to intercept large particulate impurities, reducing the load on the first filter element 44 to protect it and reduce the risk of clogging. The first filter element 44 finely filters out small particles, improving the overall purification rate.

[0031] In this embodiment, the first filter element 44 includes a first filter screen 441 and a second filter screen 442, and the second filter element 45 includes a third filter screen 451 and a fourth filter screen 452. The first filter screen 441, the second filter screen 442, the third filter screen 451 and the fourth filter screen 452 are arranged sequentially from top to bottom, and their mesh size increases sequentially from top to bottom. The arrangement of four filter screens can further improve the particulate matter interception rate, improve the cleanliness of the discharged air, and avoid secondary pollution.

[0032] The inner wall of the dust collection box 1 is provided with two oppositely arranged snap-fit ​​parts 13. The edge of the bracket 43 snaps into both snap-fit ​​parts 13. The snap-fit ​​part 13 includes two snap-fit ​​strips 131 arranged with an upper and lower gap. A snap-fit ​​groove 132 is formed between the two snap-fit ​​strips 131. The edge of the bracket 43 snaps into the snap-fit ​​groove 132. The bracket 43 and the snap-fit ​​strips 131 are detachable. After long-term use, the bracket 43 can be removed to facilitate cleaning of the filter or replacement of a new filter to ensure the filtration effect.

[0033] The top of the dust collection box 1 is provided with a fan chamber 14 and an air outlet 15. The ventilation hole 12 connects the fan chamber 14 and the air outlet 42. One end of the air outlet 15 is connected to the fan chamber 14, and the other end extends to the side wall of the dust collection box 1, forming an air outlet 16 on the side wall of the dust collection box 1 to achieve side air outlet. This allows the exhaust direction to avoid the user's head, reducing the disturbance of noise directly hitting the ears and improving the comfort of use. The fan 2 is connected to the fan chamber 14 through a first sealing ring 21. The fan 2 is covered by a cover plate 22, which is connected to the fan 2 through a second sealing ring 23 to ensure airtightness and allow negative pressure to be formed inside the dust collection box 1.

[0034] The lower surface of the cover plate 22 is provided with two limiting strips 221. The two limiting strips 221 abut against the two inner walls of the air outlet duct 15 respectively. The cooperation of the two can play a limiting role to fix the position of the cover plate 22.

[0035] The dust collection box 1 is provided with an air inlet 17, which is connected to the air inlet chamber 41. A connector 171 is provided at the air inlet 17, and a connecting pipe 172 is provided on the connector 171. The two ends of the connecting pipe 172 are connected to the air inlet 17 and the dust collection pipe 11, respectively. The dust collection pipe 11 and the connecting pipe 172 are easy to assemble and disassemble, and the connecting pipe 172 can fix the dust collection pipe 11, reducing the vibration or displacement of the dust collection pipe 11.

[0036] In other embodiments, the end of the suction pipe 11 away from the air inlet chamber 41 is connected to a suction nozzle, which can fit into the area to be cleaned, optimize the airflow path, enhance the concentration of suction power, and improve cleaning efficiency.

[0037] In this embodiment, the dust collection box 1 includes a door 19 and a box body 18 with an opening on one side. A first hook 181 is provided near the opening of the box body 18. One side of the door 19 is connected to the edge of the opening of the box body 18 by a hinge, and the other side is detachably connected to the first hook 181 by a second hook 191. When the dust collection bin 3 is full, the door 19 can be opened relatively easily, the dust collection bin 3 can be taken out, the debris inside can be emptied, the empty dust collection bin 3 can be put back into the box body 18, and the door 19 can be closed.

[0038] A door sealing ring 182 is provided on the opening edge of the box 18. The box door 19 is connected to the opening of the box 18 through the door sealing ring 182. When the box door 19 is closed, the door sealing ring 182 is squeezed between the box door 19 and the box 18 to play a sealing role, preventing external dust and debris from entering the box 18 through the door gap and ensuring the cleanliness of its internal environment.
