Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted vacuum cleaners, and in particular to a vehicle-mounted dust suction and air purification system and a vehicle body interior. Background Art

[0002] The existing vehicle dust removal generally uses a portable vacuum cleaner, which is usually a wireless vacuum cleaner developed by a third-party manufacturer or a wired vacuum cleaner connected to a 12V cigarette lighter power supply. For the former, although it is easy to use, there is the embarrassment of being stored in the vehicle for a long time and having no power when it is needed. At the same time, the temperature inside the car is very high in the high temperature environment in summer, and the built-in batteries of some vacuum cleaners with poor quality control may swell or even spontaneously combust and explode after long-term use; for the latter, it is cumbersome to connect to a 12V cigarette lighter when using it, and it is very inconvenient to connect the power cord to store it after use, and it can only be left in the trunk, which looks a bit messy. When the vehicle is driving, a child passenger in the back seat drops biscuit crumbs, and it is inconvenient for the parents in the back seat to take the vacuum cleaner from the trunk to clean it up. The dust box of the portable vacuum cleaner is small, and it is not convenient to dump it in the car after it is full, resulting in it being unable to continue to be used. Summary of the invention

[0013] At least a portion of the vacuum handle and / or the ventilation pipe can be movably arranged in the communication hole.

[0014] In one embodiment, the dust suction device further includes a limiting member, which is disposed in the inner cavity of the shell near the connecting hole, and the dust suction handle is detachably connected to the limiting member.

[0015] In one embodiment, the negative pressure device comprises:

[0022] In one embodiment, the driving motor includes a first working state and a second working state with different output powers, which are used to drive the dust collection device to work with different exhaust volumes.

[0023] In one embodiment, the negative pressure device further includes a filter device, and the filter device is detachably arranged to cover the air inlet end of the fan.

[0024] In one embodiment, the vehicle-mounted dust suction and air purification system further includes a baffle disposed in the first accommodating chamber, wherein the baffle is located on a side of the filter device facing away from the fan, and is used to prevent garbage with kinetic energy from directly entering the filter device.

[0039] The present invention provides a vehicle-mounted dust collection and air purification system 100 .

[0040] See also Figure 1In one embodiment of the present invention, the vehicle-mounted dust suction and air purification system 100 includes a shell 1, a dust suction device 2, a negative pressure device 3, and a garbage collection device 4; wherein the shell 1 is provided with a first accommodating chamber 11, and the side wall of the first accommodating chamber 11 is provided with an opening 12; the dust suction device 2 includes a ventilation pipe 21, and the ventilation pipe 21 is connected with the first accommodating chamber 11 through the opening 12; the negative pressure device 3 is arranged in the first accommodating chamber 11, and is used to extract air from the first accommodating chamber 11 so that the accommodating chamber is in a negative pressure state; the garbage collection device 4 includes a garbage collection box 41, which is detachably arranged in the first accommodating chamber 11 and is arranged corresponding to the opening 12;

[0041] It can be understood that the vehicle-mounted dust suction and air purification system 100 is not limited to the specific location in the vehicle, and can be assembled in the side door of the vehicle body or behind the rear seat of the vehicle body, thereby effectively saving space in the vehicle and solving the need of rear passengers to use and vacuum when they need to dispose of garbage; in addition, since the negative pressure device 3 of the vehicle-mounted dust suction and air purification system 100 is directly arranged in the vehicle body, the negative pressure device 3 can be directly powered by the vehicle's low-voltage power supply system, and there is no need to set up an additional battery, thereby avoiding the problem of insufficient power when carrying a rechargeable portable vacuum cleaner and the risk of built-in battery bulging and spontaneous combustion and explosion caused by long-term use; the garbage collection box 41 can be detachably connected to the first accommodating chamber 11 by means of a snap connection or magnetic attraction, and the present invention does not limit the specific connection method.

[0042] In the technical solution of the present invention, when it is necessary to clean the garbage in the car, the dust suction device 2 is placed close to the garbage. Since the negative pressure device 3 makes the first accommodating chamber 11 in a negative pressure state, the ventilation pipe 21 is connected with the first accommodating chamber 11 from the opening 12, so that the ventilation pipe 21 is also in a negative pressure state, and the garbage is sucked into the ventilation pipe 21 and enters the garbage collection box 41 corresponding to the opening 12 along the ventilation pipe 21. The garbage collection box 41 is detachably arranged in the first accommodating chamber 11. When the garbage is full, the garbage can be dumped by disassembling the garbage collection box 41. In addition, by assembling the vehicle-mounted dust suction and air purification system 100 into the vehicle body, the space in the vehicle is effectively saved, the need for rear passengers to use and suck as they need to deal with garbage is solved, and the risk of spontaneous combustion and explosion of built-in battery bulging due to insufficient power and long-term use is avoided.

[0043] In one embodiment of the present invention, the length of the ventilation pipe 21 is adjustable; the dust suction device 2 includes a dust suction handle 22, and the dust suction handle 22 is provided with an air inlet hole 221 at one end of the length direction thereof, and the air inlet hole 221 is connected to the other pipe opening of the ventilation pipe 21, and the dust suction handle 22 is used for the user to hold; specifically, the ventilation pipe 21 can adopt a bellows, and it should be noted that the bellows is a tubular elastic element made of metal or other materials, and there are many regularly arranged corrugated folds on its surface, which can produce displacement in the axial, radial and angular directions, so as to conveniently adjust the direction of the length of the ventilation pipe 21; in addition, the ventilation pipe 21 can also adopt a braided hose to provide higher pressure resistance and wear resistance, and the present invention is not limited to this. In one embodiment of the present invention, a narrow-diameter air inlet 221 can be used. According to the Bernoulli principle, reducing the diameter of the suction port can significantly increase the airflow speed. By increasing the airflow speed, the suction force is increased, and the dead corners in the vehicle are better sucked in. In another embodiment, a gradually expanding conical transition section can be designed between the air inlet 221 and the ventilation pipe 21 to reduce airflow resistance, maintain high-speed airflow entering the pipe and increase the absorption range of garbage. By adjusting the length of the ventilation pipe 21 and providing a vacuum handle 22 that is easy to hold, it is suitable for more usage scenarios and provides a larger vacuum range, thereby improving the applicability of the vehicle-mounted vacuum purification system 100.

[0044] In order to save more space in the vehicle and facilitate storage, in one embodiment of the present invention, the housing 1 further includes an inner cavity 13, a part of which is divided to form the first accommodating cavity 11, and a connecting hole 14 is provided on the side wall of the inner cavity 13 of the housing, and the connecting hole 14 is staggered with the opening of the first accommodating cavity; at least part of the vacuum handle 2 and / or the ventilation pipe 21 can be movably inserted into the connecting hole. When not in use, the vacuum device 2 can be placed in the inner cavity 13 without occupying space in the vehicle, and when the vehicle-mounted vacuum cleaning system 100 is used for vacuuming, only the vacuum handle 22 needs to be taken out, and the interior of the vehicle can be vacuumed through the ventilation pipe 21 with adjustable length.

[0045] Further, it is understandable that when the vacuum handle 22 is placed in the inner cavity 13, it is inevitable to cause shaking due to reasons such as vehicle driving, thereby making the vacuum handle 22 in the inner cavity 13 in an uncertain position, difficult to take out, and even causing damage; for this reason, in one embodiment of the present invention, the vacuum device 2 also includes a limiter 23, the limiter 23 is arranged in the inner cavity 13, and the vacuum handle 22 is detachably connected to the limiter 23. Specifically, the present invention does not limit the specific structure of the limiter 23. In one embodiment, it can be a spring buckle limiter 23, by installing a spring buckle on both sides of the connecting hole 14 or in the inner cavity 13, when the vacuum handle 223 is inserted, the buckle automatically pops out and clamps the handle. A small release button is set near the connecting hole 14, and after pressing the button, the spring buckle retracts, allowing the vacuum handle 22 to be pulled out. In another embodiment of the present invention, a magnetic adsorption type stopper 23 may be used to detachably fix the vacuum handle 22 to the inner cavity 13 by magnetic force. By providing the stopper 23, the vacuum handle 22 can be reliably stored in the inner cavity 13 when not in use.

[0046] In one embodiment of the present invention, the negative pressure device 3 includes a fan 31, a driving unit 32 and an exhaust pipe 33; wherein the fan 31 includes an air inlet end and an air outlet end which are arranged opposite to each other, and the air inlet end is arranged corresponding to the first accommodating chamber 11; the driving unit 32 is connected to the fan 31 to drive the fan 31 to rotate; the exhaust pipe 33 is connected to the air outlet end of the fan 31 at one end, and is connected to the outside air at the other end to guide the air sucked by the fan to the outside air. It can be understood that the negative pressure device 3 described in the present invention can also be an air pump, so that the first accommodating chamber 11 is in a negative pressure state by exhausting air. In addition, by arranging the fan 31, the driving unit 32 and the exhaust pipe 33, the air inlet end and the air outlet end are respectively arranged on both sides of the negative pressure device 3 to avoid inhaling the gas just discharged and improve the suction efficiency; on the other hand, the air flow path is made as straight as possible to reduce bending and obstruction and reduce energy loss.

[0047] Furthermore, in one embodiment of the present invention, the driving unit 32 includes a motor housing 1 and a driving motor: the driving motor is arranged in the motor housing 1, and includes an output shaft, and the output shaft is connected to the fan 31 to drive the fan 31 to rotate; the motor housing 1 cover is arranged outside the driving motor end, and the output shaft is exposed, and the surface of the motor housing is provided with an air inlet and an air outlet, and the air inlet is arranged corresponding to the air outlet of the fan, and one end of the exhaust pipe is connected to the air outlet of the motor housing. By arranging the motor housing 1, and arranging the air inlet of the motor housing 1 corresponding to the air outlet of the fan 31, the air discharged by the fan 31 can be completely absorbed by the motor housing 1 and discharged through the exhaust pipe 33, further avoiding the inhalation of the gas just discharged, and improving the suction efficiency.

[0048] In order to improve the applicability of the vehicle-mounted dust collection and purification system 100, in one embodiment of the present invention, the drive motor is provided with a plurality of power output gears, including at least a first working state and a second working state with different output powers, for driving the dust collection device to work with different exhaust volumes; wherein the output power of the first working state is greater than the output power of the second working state. The dust collection device 2 has a dust collection state relative to the first working state and an exhaust state relative to the second working state. It can be understood that when the drive motor is in the first working state, the drive motor has a high power output, the suction force is greater, and the dust collection device 2 is in a dust collection state; and when the air in the car is dirty or has a peculiar smell, the drive motor can also be switched to the second working state, the drive motor has a low power output, and while avoiding the absorption of items in the car, the exhaust is quickly exhausted to the outside of the car to purify the air in the car. Further, in order to finely control the actual use scenario, the drive motor can also be provided with more power output gears to provide different suction forces to meet the needs of absorbing large and small garbage and changing the exhaust speed.

[0049] In addition, it is foreseeable that when the fan 31 sucks air, it is inevitable that garbage will be sucked into the fan 31, which will cause damage to the fan 31 and discharge the garbage outside the vehicle to cause pollution. Therefore, in one embodiment of the present invention, the negative pressure device 3 also includes a filter device 34, and the filter device 34 is detachably covered on the air inlet section of the fan 31. The filter device 34 can be a filter net or a multi-layer filter structure including activated carbon, so as to prevent the exhaust gas outside the vehicle body from entering the vehicle from the exhaust pipe 33 when the negative pressure device 3 is shut down; in addition, it can be understood that in order to improve the filtering effect, the filter net needs to be cleaned or replaced with a new filter element regularly. For this reason, the filter device 34 is designed to be detachable; the present invention does not limit the specific size of the filter net, which can be changed according to the actual air permeability requirements and the size of the fan 31.

[0050] Furthermore, in one embodiment of the present invention, the vehicle-mounted dust collection and air purification system 100 further includes a baffle 5, which is disposed in the first accommodating chamber 11 and is located on the side of the filter device 34 facing away from the fan 31, so as to prevent garbage with kinetic energy from directly entering the filter device 34. It is foreseeable that when the garbage is sucked into the first accommodating chamber 11, it has kinetic energy, and if it directly enters the filter device 34 and the fan 31, it is easy to cause damage to them. By providing the baffle 5, the garbage can hit the baffle 5 and fall into the garbage collection box 41 under the action of gravity, thereby completing the garbage collection.

[0051] The present invention also proposes a vehicle body interior, which includes an on-board dust collection and air purification system. The specific structure of the on-board dust collection and air purification system refers to the above-mentioned embodiment. Since the vehicle body interior adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0052] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
