Description

Technical Field

[0001] This utility model specifically relates to the field of vehicle cleaning tools, and more specifically to a vacuum cleaner that facilitates cleaning the interior of a vehicle. Background Technology

[0002] A vacuum cleaner for vehicle interior cleaning is a tool specifically designed to clean dust and debris inside a car. When opening and closing the car door, dust from outside enters the car with the airflow. Especially in windy conditions, construction zones, or environments with poor air quality, a large amount of dust accumulates inside the vehicle. Moreover, the interior environment of a vehicle is relatively enclosed, making it easy for dust, dander, food residue, and other contaminants to breed bacteria. Therefore, it is necessary to clean the dust inside the vehicle regularly.

[0003] Car interiors are typically lined with plush floor mats, which are made of cotton fabric with a napped surface. These mats can absorb water, dust, dirt, and provide sound insulation, effectively extending the lifespan of the car. However, cotton fabrics are made up of countless tiny interwoven fibers, creating numerous micro-gaps and pores between the fibers. Dust particles can penetrate these gaps and even get stuck at the fiber intersections, rather than remaining on the surface. Simply relying on the airflow generated by traditional negative pressure suction cannot effectively clean them. Furthermore, many car interior cotton fabrics have short fibers or textured surfaces, causing dust to adhere to the roots of the fibers or become embedded in the grooves. When wiping, the fibers can hinder cleaning tools from contacting the dust, thus affecting the cleaning effect of the vacuum cleaner. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum cleaner that facilitates cleaning the interior of vehicles. A detachable pressure-boosting connector is provided at the air inlet of the dust collection hood, and the air inlet at the end of the detachable pressure-boosting connector is narrower. This increases the suction pressure at the air inlet while maintaining the same suction pressure. Combined with the rectangular array of inclined comb teeth, this improves the dust removal effect, thereby solving the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vacuum cleaner for easy cleaning of vehicle interiors includes a vacuum cleaner body, which includes two symmetrically arranged vacuum cleaner housings, and dust collection covers are installed at the ends of the vacuum cleaner housings.

[0007] The dust collection hood is snapped onto a detachable booster connector at the end away from the vacuum cleaner housing. The detachable booster connector has a hollow collection hood that fits into the end of the dust collection hood, and the inner side of the hollow collection hood is connected to the inner side of the dust collection hood through an air inlet.

[0008] As a further technical solution of this utility model, a dust filter assembly is fixedly connected to the end of the vacuum cleaner shell between the vacuum cleaner shell and the dust collection cover, and a negative pressure adsorption assembly is provided at the end of the dust filter assembly near the vacuum cleaner shell.

[0009] As a further technical solution of this utility model, each of the vacuum cleaner housings is provided with an air vent on its side, and the top of the vacuum cleaner housing is provided with an integral handle hole; and the two handle holes are interconnected.

[0010] As a further technical solution of this utility model, the hollow collection cover has a rectangular array of positioning protrusions at one end near the dust collection cover, and the end of the dust collection cover has a positioning slot corresponding to the positioning protrusion, and the positioning protrusion and the positioning slot are inserted and engaged.

[0011] As a further technical solution of this utility model, the hollow collection cover is provided with a top claw and a bottom claw symmetrically on one end near the positioning protrusion, and the top claw and the bottom claw are integrally set with the hollow collection cover, while the other end of the top claw and the bottom claw are respectively engaged with the dust collection cover.

[0012] As a further technical solution of this utility model, the longitudinal section of the hollow collection cover is generally triangular, and the end of the hollow collection cover away from the dust collection cover is also provided with inclined comb teeth in a rectangular array. Each inclined comb tooth and the connection position of the hollow collection cover are also provided with multiple triangular shrinkage grooves, and the bottom of the inclined comb tooth and the bottom of the hollow collection cover are integrally set.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the hollow collection cover is first aligned with the opening of the dust collection cover, and the positioning protrusion at the end of the hollow collection cover cooperates with the positioning slot at the end of the dust collection cover. The positioning protrusion is inserted into the inner side of the positioning slot, thereby positioning the hollow collection cover at the end of the dust collection cover. At the same time, the top claw and bottom claw symmetrically arranged at the end of the hollow collection cover cooperate with each other to quickly fix the hollow collection cover to the end of the dust collection cover. It can also be quickly disassembled and assembled according to the usage.

[0015] 2. In this utility model, the hollow collection hood is arranged in a triangular shape, and the end of the hollow collection hood away from the dust collection hood is tapered. Therefore, the air inlet of the hollow collection hood is narrower and longer than that of the dust collection hood. Since the pressure during negative pressure adsorption remains unchanged, the reduced area of ​​the air inlet increases the airflow pressure during negative pressure adsorption, thereby increasing the adsorption pressure and improving the adsorption effect. In addition, the thickness of the end of the hollow collection hood is thinner, and the extended part can penetrate into relatively narrow gaps to adsorb dust, thereby improving the cleaning effect of dust.

[0016] 3. In this utility model, when cleaning dust from the surface of cotton fabric laid at the bottom of a vehicle, the bottom of the hollow collection cover needs to be attached to the surface of the cotton fabric, and the hollow collection cover needs to be pushed towards the air inlet. At this time, the inclined comb teeth at the end of the hollow collection cover can be inserted into the root of the cotton fabric fibers to clean the dust remaining at the root of the fibers. With the negative pressure airflow of the air inlet, the dust at the root of the fibers enters the inner side of the dust collection cover, further improving the dust cleaning effect. At the same time, each inclined comb tooth is also provided with a shrinkage groove. With the toughness of the shrinkage groove itself, the inclined comb tooth can be adjusted according to the concavity and convexity of the cotton fabric. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-9 This utility model provides a vacuum cleaner that facilitates cleaning the interior of a vehicle, including a vacuum cleaner body, which includes two symmetrically arranged vacuum cleaner shells 1, and a dust collection cover 2 is installed at the end of the vacuum cleaner shell 1.

[0030] The dust collection hood 2 is attached to a detachable booster connector 3 at the end away from the vacuum cleaner housing 1. The detachable booster connector 3 has a hollow collection hood 31 that fits into the end of the dust collection hood 2, and the inner side of the hollow collection hood 31 is connected to the inner side of the dust collection hood 2 through an air inlet.

[0031] Furthermore, a dust filter assembly 4 is fixedly connected to the end of the vacuum cleaner housing 1 between the vacuum cleaner housing 1 and the dust collection cover 2, and a negative pressure adsorption assembly 5 is provided at the end of the dust filter assembly 4 near the vacuum cleaner housing 1.

[0032] Furthermore, each of the vacuum cleaner housings 1 has an air vent on its side, and the top of the vacuum cleaner housing 1 is integrally provided with a handle hole 11; and the two handle holes 11 are interconnected.

[0033] By adopting the above technical solution, the airflow inside the dust collection cover 2 is extracted by the negative pressure adsorption component 5, so that the inside of the dust collection cover 2 is negative pressure. The external airflow carries the dust into the dust collection cover 2 through the air inlet. After the airflow is filtered by the dust filter component 4, it is discharged from the air outlet on the side of the vacuum cleaner housing 1. The dust is left inside the dust filter component 4.

[0034] Furthermore, the hollow collection cover 31 has a rectangular array of positioning protrusions 36 near the dust collection cover 2, and the end of the dust collection cover 2 has a positioning slot 21 corresponding to the positioning protrusions 36, and the positioning protrusions 36 and the positioning slot 21 are inserted and engaged.

[0035] Furthermore, the hollow collection cover 31 is provided with a top claw 32 and a bottom claw 35 symmetrically on one end near the positioning protrusion 36, and the top claw 32 and the bottom claw 35 are integrally formed with the hollow collection cover 31, while the other ends of the top claw 32 and the bottom claw 35 are respectively engaged with the dust collection cover 2.

[0036] By adopting the above technical solution, the hollow collection cover 31 is first aligned with the opening of the dust collection cover 2, and the positioning protrusion 36 at the end of the hollow collection cover 31 cooperates with the positioning slot 21 at the end of the dust collection cover 2. The positioning protrusion 36 is inserted into the inner side of the positioning slot 21, thereby positioning the hollow collection cover 31 at the end of the dust collection cover 2. At the same time, the top claw 32 and bottom claw 35 symmetrically arranged at the end of the hollow collection cover 31 cooperate with each other to quickly fix the hollow collection cover 31 to the end of the dust collection cover 2. It can also be quickly disassembled and assembled according to the usage.

[0037] More specifically, the longitudinal section of the hollow collection cover 31 is generally triangular, and the end of the hollow collection cover 31 away from the dust collection cover 2 is provided with inclined comb teeth 33 in a rectangular array. Each of the inclined comb teeth 33 and the connection position of the hollow collection cover 31 is also provided with multiple triangular shrinkage grooves 34, and the bottom of the inclined comb teeth 33 and the bottom of the hollow collection cover 31 are integrally set.

[0038] By adopting the above technical solution, when cleaning the dust on the surface of the cotton fabric laid at the bottom of the vehicle, the bottom of the hollow collection cover 31 needs to be attached to the surface of the cotton fabric, and the hollow collection cover 31 needs to be pushed towards the air inlet. At this time, the inclined comb teeth 33 at the end of the hollow collection cover 31 can be inserted into the root of the cotton fabric fibers to clean the dust remaining at the root of the fibers. With the negative pressure airflow of the air inlet, the dust at the root of the fibers enters the inner side of the dust collection cover 2, further improving the dust cleaning effect. At the same time, each inclined comb tooth 33 is also provided with a shrinkage groove 34. With the toughness of the shrinkage groove 34 itself, the inclined comb tooth 33 can be adjusted according to the concavity and convexity of the cotton fabric.

[0039] The dust collection cover 2 has a mounting slot at the bottom near the vacuum cleaner housing 1, and a positioning protrusion that engages with the mounting slot is located at the corresponding position on the vacuum cleaner housing 1. During installation, the mounting slot at the bottom of the dust collection cover 2 should be aligned with the positioning protrusion at the bottom of the vacuum cleaner housing 1 to ensure stability after installation. A disassembly press buckle 6 is also movably connected to the upper inner side of the vacuum cleaner housing 1.

[0040] One end of the disassembly press buckle 6 is movably connected to the vacuum cleaner housing 1 via a pin, and the other end is snapped into the top of the inner side of the dust collection cover 2. A return spring is also fixedly connected to the bottom of the disassembly press buckle 6. Applying an upward pushing force to the disassembly press buckle 6 and pressing the disassembly press buckle 6 downward will disengage the disassembly press buckle 6 from the dust collection cover 2, allowing the dust collection cover 2 to be disassembled.

[0041] The negative pressure adsorption component 5 includes a sealing shell, wherein one end of the sealing shell is connected to the inner side of the dust collection cover 2, and the other side is connected to the inner side of the vacuum cleaner housing 1. An air-drawing impeller is provided on the inner side of the sealing shell, and a rotary motor for driving is fixedly connected to the outer side of the sealing shell.

[0042] The output shaft of the rotary motor passes through the sealed shell and is fixedly connected to the impeller inside. The rotary motor drives the impeller to rotate rapidly, which quickly draws out the airflow inside the dust collection hood 2, creating a negative pressure inside the dust collection hood 2. The other end of the dust collection hood 2 is provided with an air inlet, through which external airflow can enter the inside of the dust collection hood 2.

[0043] A push-button switch 7 is also fixedly connected to the top of the vacuum cleaner housing 1, and the push-button switch 7 is electrically connected to the rotary motor in the negative pressure suction assembly 5. Specific Implementation

[0044] Example 1

[0045] An energy storage structure, such as a battery or lithium battery, can be installed inside the vacuum cleaner housing 1. The energy storage structure is electrically connected to the rotary motor and the push switch 7. When the push switch 7 is pressed, a circuit is formed between the rotary motors to supply power to the rotary motors.

[0046] Example 2

[0047] A plug-in wire can be installed on the side of the vacuum cleaner housing 1 to connect to an external power supply. The plug type is the same as that of the cigarette lighter signal inside the vehicle. The plug-in wire is electrically connected to the rotary motor and the push switch 7 respectively.

[0048] Insert the plug with the wire into the vehicle's cigarette lighter socket, and then press the push switch 7 to supply power to the rotary motor via the vehicle's power supply.

[0049] The working principle of this utility model is as follows: When using it, first determine whether to install the detachable pressure connector 3 based on the cleaning location. When cleaning smooth surfaces and areas with large operating spaces, such as seats or hollow areas, the air inlet at the end of the dust collection hood 2 can be used directly for cleaning. The drive motor in the negative pressure adsorption component 5 drives the impeller to rotate, extracting the gas inside the dust collection hood 2, causing the air pressure inside the dust collection hood 2 to drop. The negative pressure in the dust collection hood 2 then allows external airflow to carry dust into the dust collection hood 2. When cleaning dust from cotton fabrics laid at the bottom of the vehicle or in small spaces, the hollow collection hood 31 can be installed at the end of the dust collection hood 2. Align the hollow collection hood 31 with the opening of the dust collection hood 2, and ensure that the positioning protrusion 36 at the end of the hollow collection hood 31 cooperates with the positioning slot 21 at the end of the dust collection hood 2. Insert the positioning protrusion 36 into the inside of the positioning slot 21 to position the hollow collection hood 31 at the end of the dust collection hood 2. Simultaneously, symmetrically arranged... The top claw 32 and the bottom claw 35 work together to quickly fix the hollow collection cover 31 to the end of the dust collection cover 2. The hollow collection cover 31 is triangular in shape, and the end of the hollow collection cover 31 away from the dust collection cover 2 is conical. Therefore, the air inlet of the hollow collection cover 31 is narrower and longer than the air inlet of the dust collection cover 2. Since the pressure during negative pressure adsorption remains unchanged, the reduced area of ​​the air inlet increases the airflow pressure during negative pressure adsorption, thereby increasing the adsorption pressure. Then, the bottom of the hollow collection cover 31 is pressed against the surface of the cotton fabric, and the hollow collection cover 31 is pushed towards the air inlet. At this time, the inclined comb teeth 33 at the end of the hollow collection cover 31 can be inserted into the root of the cotton fabric fibers to clean the dust remaining at the root of the fibers. At the same time, each inclined comb tooth 33 is also provided with a shrinkage groove 34. With the toughness of the shrinkage groove 34 itself, the inclined comb tooth 33 can be adjusted according to the concavity and convexity of the cotton fabric. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
