Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically a portable vacuum cleaner. Background Technology

[0002] Vacuum cleaners can be classified into upright, canister, and portable types based on their structure. The working principle of a vacuum cleaner is that an electric motor drives blades to rotate at high speed, creating negative air pressure within a sealed casing to suck up dust and debris.

[0003] When cleaning the house, there are many corners that are difficult for the vacuum cleaner heads of some large vacuum cleaners to reach, so some small vacuum cleaners are needed to operate them.

[0004] While some small vacuum cleaners can be used to clean up dust, they cannot be used in different scenarios, such as spacious or small crevices, and cannot meet various needs, resulting in low applicability. Therefore, it is necessary to propose a portable vacuum cleaner to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a portable vacuum cleaner with different nozzles, which can be used in different scenarios and cleaning needs, thereby improving the versatility of the device.

[0007] Two fixed plates are fixedly connected to the upper end face of the housing and are distributed in a front-to-back manner. A positioning plate located outside the housing is fixedly connected to the upper end face of the filter screen. A pressure plate located above the positioning plate is provided on the opposite side of the two fixed plates. The lower end faces of the two pressure plates are slidably connected to the housing. A first spring is installed between the opposite side of the two pressure plates and the fixed plate.

[0008] A second suction head can be provided at one end of the suction channel. The end of the second suction head away from the suction channel is a telescopic tube, and the end of the first suction head away from the suction channel has a trapezoidal structure.

[0009] In order to collect dust, as a preferred embodiment of the portable vacuum cleaner of this utility model, a material guide groove is provided on the lower end face of the housing, and a dust collection box is threadedly connected inside the material guide groove.

[0010] To protect the motor, in a preferred embodiment of this portable vacuum cleaner, the outer wall of the motor is provided with a protective shell that is fixedly connected to the housing, and a battery compartment is installed on the right side of the protective shell.

[0011] For handheld operation, as a preferred embodiment of this portable vacuum cleaner, a handheld handle is fixedly connected to the right side of the upper surface of the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] Please see Figures 1 to 5A portable vacuum cleaner includes a housing 1, a motor 101 mounted on the right side of the housing 1, a fan blade 102 fixedly connected to the output end of the motor 101 mounted inside the housing 1, a filter screen 2 inserted inside the housing 1, and a suction channel 4 connected to the left side of the housing 1. Two mounting plates 403 arranged vertically are mounted on the inner wall of the suction channel 4. Each of the two mounting plates 403 has a limiting groove 404 on one side. Limiting rods 401 matching the limiting grooves 404 are movably connected to the upper and lower sides of the outer wall of the suction channel 4. A second spring 402 located outside the suction channel 4 is mounted on the outer wall of each of the two limiting rods 401. A first suction head 5 is provided at one end of the suction channel 4, and a second suction head 6 can also be provided at one end of the suction channel 4. The end of the second suction head 6 away from the suction channel 4 is a telescopic tube, and the end of the first suction head 5 away from the suction channel 4 has a trapezoidal structure.

[0022] Two fixed plates 201 arranged in a front-to-back pattern are fixedly connected to the upper end face of the housing 1. A positioning plate located outside the housing 1 is fixedly connected to the upper end face of the filter screen 2. A pressure plate 202 located above the positioning plate is provided on the opposite side of the two fixed plates 201. The lower end faces of the two pressure plates 202 are slidably connected to the housing 1. A first spring 203 is installed between the opposite side of the two pressure plates 202 and the fixed plate 201.

[0023] In this embodiment: when using a vacuum cleaner, the motor 101 drives the fan blade 102 to rotate, thereby directly adsorbing external dust through the vacuum channel 4. During use, different suction heads, such as the first suction head 5 and the second suction head 6, can be set to adapt to different scenarios and cleaning needs. Specifically, when used in a relatively spacious environment, the limiting rod 401 can be pulled outwards from the vacuum channel 4, stretching the second spring 402. Simultaneously, one end of the first suction head 5 is inserted into the vacuum channel 4, positioning it within the mounting plate 403. Then, the limiting rod 401 is slowly released, allowing it to enter the limiting groove 4 under the action of the second spring 402. Within 04, the first vacuum head 5, the vacuum channel 4, and the mounting plate 403 can be limited and fixed, enabling the installation and use of the first vacuum head 5. Conversely, when cleaning some crevices, the limiting rod 401 can be pulled outward of the vacuum channel 4, and the second spring 402 will be stretched until the limiting rod 401 separates from the limiting groove 404 and the limiting hole on the first vacuum head 5. Then, the first vacuum head 5 and the vacuum channel 4 can be disassembled, and the second vacuum head 6 can be installed with the vacuum channel 4 by installing the first vacuum head 5. Thus, the first vacuum head 5, the second vacuum head 6, and the vacuum channel 4 can work together to meet different scenarios and cleaning needs, thereby improving the versatility of the equipment.

[0024] Secondly, when it is necessary to clean the filter screen 2, the pressure plate 202 can be slid away from each other, the first spring 203 is compressed until the pressure plate 202 is separated from the positioning plate, and then the positioning plate can be pulled upward to remove the filter screen 2 from the housing 1 for cleaning, thus achieving the effect of easy cleaning of the filter screen 2.

[0025] As a technical optimization of this utility model, a material guide groove 104 is provided on the lower end face of the housing 1, and a dust collection box 3 is threadedly connected inside the material guide groove 104.

[0026] In this embodiment, the dust entering the housing 1 can fall into the dust collection box 3 through the guide channel 104 and be collected in a concentrated manner.

[0027] As a technical optimization of this utility model, the outer wall of the motor 101 is provided with a protective shell that is fixedly connected to the housing 1, and a battery box 103 is installed on the right side of the protective shell.

[0028] In this embodiment: the motor 101 can be protected by a protective shell, and the battery box 103 facilitates the installation of batteries to provide power to the motor 101. The outer wall of the battery box 103 is equipped with control buttons for controlling the operation of the motor 101.

[0029] As a technical optimization of this utility model, a hand handle is fixedly connected to the right side of the upper end face of the housing 1.

[0030] In this embodiment, a handheld stick is used to facilitate the operation of the handheld device.

[0031] Working principle: When using the vacuum cleaner, the motor 101 drives the fan blades 102 to rotate, which directly adsorbs external dust through the suction channel 4. The adsorbed dust enters the housing 1 and falls into the dust collection box 3 through the guide groove 104. During use, different suction heads, such as the first suction head 5 and the second suction head 6, can be set to adapt to different scenarios and cleaning needs. Specifically, when using it in a relatively spacious environment, the limiting rod 401 can be pulled outward of the suction channel 4, the second spring 402 is stretched, and one end of the first suction head 5 is inserted into the suction channel 4, so that the first suction head 5 is located in the mounting plate 403. Then, the limiting rod 401 is slowly released, so that the limiting rod 401 passes through the first suction head 5 under the action of the second spring 402. The limiting hole is inserted into the limiting groove 404, thereby limiting and fixing the first vacuum head 5, the vacuum channel 4, and the mounting plate 403, realizing the installation and use of the first vacuum head 5. Conversely, when cleaning some gaps, the limiting rod 401 can be pulled to the outside of the vacuum channel 4, and the second spring 402 is stretched until the limiting rod 401 separates from the limiting groove 404 and the limiting hole on the first vacuum head 5, thereby disassembling the first vacuum head 5 from the vacuum channel 4. Then, the second vacuum head 6 is installed with the vacuum channel 4 by installing the first vacuum head 5. The telescopic tube on the second vacuum head 6 can be pulled according to the depth of the gap. Thus, the first vacuum head 5, the second vacuum head 6, and the vacuum channel 4 can work together to be applicable to different scenarios and cleaning needs, thereby improving the versatility of the equipment.

[0032] Secondly, when it is necessary to clean the filter screen 2, the pressure plate 202 can be slid away from each other, and the first spring 203 is compressed until the pressure plate 202 is separated from the positioning plate. Then the positioning plate can be pulled upward to remove the filter screen 2 from the housing 1 for cleaning, thus achieving the effect of easy cleaning of the filter screen 2. After cleaning, the two pressure plates 202 can be pushed away from each other and close to the fixing plate 201 to compress the first spring 203. Then the filter screen 2 can be inserted into the housing 1, and the pressure plate 202 can be released. Under the elastic force of the first spring 203, the pressure plate 202 slides to the top of the positioning plate and presses and fixes the positioning plate.

[0033] Finally, the dust collection box 3 can be separated from the guide trough 104 by rotating the screw to remove the dust inside the dust collection box 3.
