Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a hand-held vacuum cleaner with a rounded corner air guide structure. Background Art

[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structure. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in a sealed shell, absorb dust, and then use a filter sleeve installed in the vacuum cleaner to filter the dust. However, traditional vacuum cleaners have the following shortcomings when used:

[0003] 1. The filter cover of the vacuum cleaner has a relatively simple structure and is prone to blockage when filtering dust, which affects the efficiency of the vacuum cleaner.

[0004] Therefore, we propose a portable vacuum cleaner with a rounded corner air guide structure. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A portable vacuum cleaner with a rounded corner air guide structure, comprising:

[0008] A cup body, a filter sleeve is installed inside the cup body for filtering dust, a dust cavity is formed between the cup body and the filter sleeve, an air guide pipe is fixedly penetrated between the filter sleeve and the cup body for conveying wind and dust, an air outlet is opened on the outer wall of the filter sleeve, the outlet end of the air guide pipe is fixedly connected to the air outlet, the bottom end of the air guide pipe is bent and the outlet end of the air guide pipe is R-shaped for guiding the wind to rotate;

[0009] The outer wall of the filter sleeve is integrally formed with a guide plate for guiding the wind, the guide plate is located on one side of the air outlet, and the guide plate and the cup body are in conflict;

[0010] The bottom of the filter sleeve is provided with an air outlet for exhausting air.

[0011] In a possible design, a fixing ring and a sealing ring are provided on the outer wall of the filter sleeve, the fixing ring is fixed to the cup body, and the sealing ring is in contact with the inner wall of the cup body.

[0012] In a possible design, a connecting ring is integrally formed at the top end of the filter sleeve, and the connecting ring is open.

[0013] In a possible design, a reinforcement ring is fixedly provided on the top inner wall of the cup body, and the air guide pipe passes through the reinforcement ring.

[0015] In a possible design, the guide plate is U-shaped, and the opening of the guide plate is arranged horizontally.

[0016] In the present application, when in use, wind carries dust through the air duct. Under the guidance of the air duct and the guide plate, the dust comes out from the outlet and rotates around the filter sleeve at high speed. Under the action of the filter sleeve, the dust is retained in the dust chamber and rotates, while the wind passes through the filter sleeve and is discharged from the exhaust port.

[0017] Beneficial effects:

[0018] In the utility model, the portable vacuum cleaner has a rounded air guide structure. Through the arrangement of the air guide pipe, under the guidance of the air guide pipe, dust can be better rotated when entering the dust chamber, thereby preventing dust from adhering to the outer wall of the filter sleeve and blocking the filter sleeve, thereby ensuring the use efficiency of the vacuum cleaner.

[0019] In the utility model, the portable vacuum cleaner has a rounded air guide structure, and the connection between the cup body and the air guide pipe can be reinforced by setting a reinforcement ring, thereby improving the overall strength of the structure;

[0020] In the utility model, the dust can be guided to form a better rotating state, thereby preventing the dust from blocking the filter sleeve, ensuring the use efficiency of the vacuum cleaner, and reinforcing the structure to improve the overall strength of the structure.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1

[0027] Reference Figure 1-Figure 3 , an air guide structure, which is used in the field of vacuum cleaners, includes a cup body 1, a filter sleeve 2, an air guide pipe 3 and other components. The cup body 1 is the main part of the vacuum cleaner and is used to contain dust. The filter sleeve 2 is installed on the inner side of the cup body 1 and mainly plays the role of filtering dust. A dust cavity 9 is formed between the filter sleeve 2 and the cup body 1, and the dust cavity 9 is used to temporarily store the dust sucked in by the vacuum cleaner.

[0028] The air duct 3 is an important component of the present invention, which penetrates the filter sleeve 2 and is fixedly connected to the filter sleeve 2. The outlet end of the air duct 3 is fixedly connected to the air outlet 8 on the filter sleeve 2. The bottom end of the air duct 3 is bent and its outlet end is R-shaped. Such a design can effectively guide the wind to rotate, thereby preventing dust from blocking the filter sleeve 2.

[0029] A guide plate 7 is integrally formed on the outer wall of the filter sleeve 2. The guide plate 7 is located on one side of the air outlet 8 and contacts the cup body 1. The design of the guide plate 7 helps to guide the wind so that the dust enters the dust chamber 9 and rotates at a high speed.

[0030] Example 2

[0031] Improved on the basis of Example 1:

[0032] An exhaust port 11 is provided at the bottom of the filter sleeve 2 for exhausting the filtered air. The design of the exhaust port 11 enables the vacuum cleaner to maintain a good ventilation state during operation.

[0033] A fixing ring 4 and a sealing ring 10 are also provided on the outer wall of the filter sleeve 2. The fixing ring 4 is used to fix the filter sleeve 2 and the cup body 1 to ensure that the filter sleeve 2 does not move or fall off when the vacuum cleaner is working. The sealing ring 10 contacts the inner wall of the cup body 1 to play a sealing role and prevent dust from leaking from the gap between the filter sleeve 2 and the cup body 1.

[0034] A connecting ring 5 is integrally formed at the top of the filter sleeve 2, and the connecting ring 5 is open.

[0035] At the same time, a reinforcement ring 6 is fixedly provided on the top inner wall of the cup body 1, and the air duct 3 passes through the reinforcement ring 6. The provision of the reinforcement ring 6 can enhance the stability of the air duct 3 and improve the overall strength of the structure.

[0036] It is worth mentioning that the inner diameter of the top end of the filter sleeve 2 is smaller than the inner diameter of the bottom end. This design makes the top of the filter sleeve 2 more compact and can better cooperate with the cup body 1.

[0037] In addition, the guide plate 7 is U-shaped, and its opening is arranged horizontally. Such a design enables the guide plate 7 to more effectively guide the direction of the wind and increase the rotation effect of the wind in the dust chamber 9 at the same time.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
