[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0047] See Figures 1-16 A portable vacuum cleaner includes a main unit 1, a side air outlet 2 connected to the outside air on the main unit 1, an air outlet adjustment component 3 inside the main unit 1, a ventilation structure 4 on the air outlet adjustment component 3, the air outlet adjustment component 3 being flexibly and movable inside the main unit 1 and having a first position and a second position, and an end air outlet 5 at the end of the main unit 1 corresponding to the air outlet adjustment component 3.

[0048] The air outlet adjustment component 3 is positioned at the first position under elastic action and blocks the end air outlet 5 of the main unit 1, and the ventilation structure 4 is connected to the side air outlet 2 to form a side air outlet structure on the main unit 1.

[0049] The air outlet adjustment component 3 moves along the second position direction and moves to the position of its blocked side air outlet 2, with the end air outlet 5 in an open state, so as to form an end air outlet structure on the main unit 1.

[0050] By incorporating an air outlet adjustment component 3 on the main unit 1, the portable vacuum cleaner can flexibly switch between side air outlets and end air outlets, ensuring effective cleaning of dust and debris in various usage scenarios, especially in hard-to-reach corners, thus improving the vacuum cleaner's efficiency and cleaning effect. When corners need cleaning, the air outlet adjustment component 3 can be moved to a second position, blocking the side air outlet 2 and opening the end air outlet 5, allowing air to be blown out from the end air outlet 5, effectively cleaning dust and debris in the corners.

[0051] The portable vacuum cleaner also includes an end air outlet pipe 6 that is detachably installed on the main unit 1. The end air outlet pipe 6 is installed on the main unit 1 and triggers the air outlet adjustment component 3 to move along the second position direction to open the end air outlet 5, and the end air outlet 5 is connected to the end air outlet pipe 6. The end air outlet pipe 6 is detached from the main unit 1, and the air outlet adjustment component 3 is elastically reset to the first position.

[0052] When the end air outlet 6 is detached from the main unit 1, the air outlet adjustment component 3 automatically resets to the first position under the elastic action, ensuring that the main unit of the vacuum cleaner is in the first use state, and the gas is discharged from the side air outlet 2, preventing the gas from leaking from the end air outlet 5, and preventing the gas entering the main unit 1 from blowing upward when the main unit of the vacuum cleaner is in the first use state.

[0053] By equipping the end air outlet pipe 6 on the end of the main unit 1, users can easily switch the air outlet mode of the vacuum cleaner. When the end air outlet pipe 6 is not in use, the end air outlet pipe 6 can be detached from the air outlet adjustment component 3 and automatically reset to the first position, keeping the vacuum cleaner clean and portable.

[0054] The air outlet regulating component 3 includes a sealing element 7. The sealing element 7 has a first opening groove 8 forming a ventilation structure 4. The sealing element 7 moves along the second position direction with the air outlet regulating component 3. The first opening groove 8 is offset from the side air outlet 2 of the main unit 1. The sealing element 7 blocks the side air outlet 2. One side of the air outlet regulating component 3 and the inner side of the main unit 1 form a sealing fit through the sealing element 7 to prevent gas from flowing outward to the side air outlet of the main unit 1. The other side of the air outlet regulating component 3 and the inner side of the main unit 1 leave an air outlet gap 12 for airflow to enter the end air outlet 5. When the sealing element 7 blocks the side air outlet 2 and the end air outlet 5 is opened, it ensures that the gas entering the main unit 1 can flow to the end air outlet 5 along the air outlet gap 12.

[0055] The design of the seal 7 ensures that the gas entering the main unit 1 will not leak from the side air outlet 2 in the end air outlet mode, thus avoiding noise generated by the vacuum cleaner during operation and ensuring that the gas is blown out along the end air outlet 5, thereby improving the blowing effect of the main unit in the second use state.

[0056] The main unit 1 is provided with an air guide seat 9, and the air guide seat 9 is provided with a ventilation slot 10. An elastic element 11 is provided between the air outlet adjustment component 3 and the air guide seat 9. One end of the elastic element 11 abuts against the air guide seat 9, and the other end of the elastic element 11 abuts against the air outlet adjustment component 3. The air outlet adjustment component 3 is elastically and movably set in the main unit 1 through the elastic element 11.

[0057] The elastic element 11 is a spring;

[0058] In this embodiment, the top of the air guide seat 9 is provided with a first annular limiting groove, one end of the elastic member 11 is limited on the first annular limiting groove, the movable member 14 of the air outlet adjustment component 3 is provided with a second annular limiting groove, and the other end of the elastic member 11 is limited on the second annular limiting groove.

[0059] When the air outlet adjustment component 3 is in the first position, the airflow entering the main unit 1 flows out of the main unit 1 along the ventilation slot 10 and the side air outlet 2.

[0060] The air outlet adjustment component 3 is in the second position, and the airflow entering the main unit 1 flows out of the main unit 1 along the ventilation slot 10, the air outlet gap 12 and the end air outlet 5.

[0061] The host 1 is equipped with a brushed or brushless motor 13 for drawing airflow into the host 1, and the air guide seat 9 is positioned on the end of the brushed or brushless motor 13.

[0062] The design of the brushed or brushless motor 13 makes the vacuum cleaner highly efficient, especially the brushless motor, which is characterized by low noise.

[0063] In this embodiment, the air guide seat 9 is provided with a plurality of spaced ventilation slots 10 to form an air outlet grille.

[0064] In this embodiment, a positioning block is provided on the top of the brushed or brushless motor 13, and a limiting cavity 30 is provided at the bottom of the air guide seat 9. The limiting cavity 30 of the air guide seat 9 covers the positioning block of the brushed or brushless motor 13, so that the air guide seat 9 is positioned and installed on the top of the brushed or brushless motor 13.

[0065] The air outlet adjustment assembly 3 includes a movable part 14 and a sealing part 7. The movable part 14 has an extension block 15 extending toward the side air outlet 2. The extension block 15 has a limiting groove 17 for installing the sealing part 7. The ventilation structure 4 is disposed on the extension block 15 and the sealing part 7.

[0066] The movable part 14 and the sealing part 7 move along the second position direction with the air outlet adjustment assembly 3. The ventilation port structure 4 is misaligned with the side air outlet 2 of the main unit 1. The sealing part 7 blocks the side air outlet 2. An air outlet gap 12 is left between the other side of the movable part 14 and the inner side of the main unit 1 to allow airflow to enter the end air outlet 5.

[0067] In this embodiment, the sealing element 7 can be fixed to the limiting groove 17 of the extension block 15 by adhesive. When the air outlet adjustment component 3 is in the second position, the extension block 15 forms a flexible sealing fit with the inner side of the main unit 1 housing through the sealing element 7. Without the sealing element 7, a rigid sealing fit is formed between the extension block 15 and the inner side of the main unit 1 housing. With prolonged use, the air outlet adjustment component 3 will be pushed, which will cause wear between the extension block 15 and the inner side of the main unit 1 housing, resulting in poor sealing performance. Therefore, the sealing element 7 can solve this technical problem.

[0068] The extension block 15 of the movable component 14 is provided with a second opening groove 16 forming the ventilation structure 4;

[0069] The air outlet adjustment assembly 3 also includes a movable valve core 18, a positioning groove 19 is provided on the end of the movable part 14, a plug-in part 20 is provided at one end of the movable valve core 18 to be inserted into the positioning groove 19, and an elastic element 11 is provided on the movable part 14.

[0070] The elastic element 11 releases its elastic force to position the air outlet regulating component 3 in the first position, and the movable valve core 18 blocks the end air outlet 5;

[0071] The movable valve core 18, under the action of external force, squeezes the elastic element 11 and causes the movable element 14 to move in the direction close to the side air outlet 2, so that the air outlet adjustment component 3 moves in the second position direction and opens the end air outlet 5.

[0072] The host 1 is provided with a fixing member 21, which is inserted and installed on the end of the host 1.

[0073] The fixing member 21 is provided with a boss 22, the boss 22 is provided with an inner cavity 23 for inserting the movable member 14, the end air outlet 5 is provided on the boss 22 and communicates with the inner cavity 23, and there is an installation gap 24 between the fixing member 21 and the boss 22 for inserting the end air outlet 6. The end air outlet 6 is detachably installed on the main unit 1 through the installation gap 24.

[0074] The fixing member 21 and the boss 22 are provided with a guide slot 25 that connects the installation gap 24. The movable valve core 18 is provided with a guide block 26 that is inserted into the guide slot 25. The end air outlet pipe 6 is inserted into the installation gap 24 and acts on the guide block 26 to trigger the movable valve core 18 and the movable member 14 to move in the direction close to the side air outlet 2. The guide block 26 is limited to move on the guide slot 25.

[0075] In this embodiment, the end air outlet 6 is a hollow pipe. The top of the boss 22 and the movable valve core 18 are stepped with a slope. The top of the movable valve core 18 is provided with a first slope and a first slope opening. The position of the first slope is higher than the position of the first slope opening. The top of the boss 22 is provided with a second slope opening that forms the end air outlet 5. The second slope opening is provided corresponding to the first slope. The top of the boss 22 is provided with a second slope that is provided corresponding to the first slope opening. The position of the second slope is higher than the position of the second slope opening.

[0076] In this embodiment, because the movable valve core 18 is provided with a guide block 26 for inserting into the guide slot 25, relative rotation between the movable valve core 18 and the fixed member 21 is prevented. The second inclined opening also corresponds to the first inclined surface, and the first inclined opening corresponds to the second inclined surface. When the end air outlet pipe 6 is inserted into the installation gap 24, the end air outlet pipe 6 pushes the movable valve core 18 through the guide block 26 located within the installation gap 24, thereby compressing the elastic member 11 between the air guide seat 9 and the movable member 14. The first and second inclined openings open. Through the two inclined openings and the two inclined surfaces, the gas entering the main unit 1 is prevented from being directly blown out of the end air outlet pipe 6. When the first and second inclined openings are open, the two inclined surfaces slow down the flow rate.

[0077] When the end air outlet 6 is removed, the first inclined surface seal forms the second inclined surface opening of the end air outlet 5, and the second inclined surface seals the first inclined surface opening.

[0078] In this embodiment, the air guide seat 9 is provided with a locking groove 29 corresponding to the extension block 15. When the end air outlet pipe 6 is installed on the main unit 1 and the air outlet adjustment component 3 is triggered to move in the second position direction, the extension block 15 of the movable member 14 is inserted into the locking groove 29. The locking groove 29 serves to prevent air from entering and to guide and limit the movement, ensuring that the extension block 15 of the movable member 14 and the sealing member 7 move in the direction of the sealing side air outlet 2, and that the air outlet adjustment component 3 is in the second position, with the extension block 15 and the sealing member 7 limited in the locking groove 29.

[0079] In this embodiment, a limiting ring 32 is provided on the movable valve core 18, and a guide block 26 is disposed on the side of the limiting ring 32. When the end air outlet pipe 6 is detached from the main unit 1, the elastic member 11 drives the movable member 14 and the movable valve core 18 to move along the first position direction of the air outlet regulating assembly 3. The limiting ring 32 cooperates with the bottom of the fixing member 21 to prevent the movable valve core 18 from disengaging from the fixing member 21 and to limit the movement stroke of the movable valve core 18 and the movable member 14. This ensures that the air regulating assembly 3 is in the first position, with the side air outlet 2 open and the end air outlet 5 closed.

[0080] The movable valve core 18 is provided with a limiting ring 32. When the air outlet adjustment component 3 is in the first position, the limiting ring 32 of the movable valve core 18 abuts against the fixing member 21.

[0081] The main unit 1 includes a first housing 27 and a second housing 28. An installation compartment for installing a brushed or brushless motor 13, an air guide seat 9, an air outlet adjustment component 3 and a fixing component 21 is provided between the first housing 27 and the second housing 28.

[0082] In this embodiment, both the first housing 27 and the second housing 28 are provided with grip grooves for inserting a human hand to form a handle on the first housing 27 and the second housing 28, so as to facilitate the user's use and carrying.

[0083] When dust attached to the corners of the floor is blown out, if the tube connecting the nozzle to the main unit 1 is a flexible hose, the nozzle should be pointed upwards towards the corner. When dust or other debris is stirred up above the corner, the nozzle can effectively suck it up. The flexible hose connection design allows the nozzle to be flexibly adjusted to ensure that when dust is blown out of the corner, it can promptly suck up the stirred-up dust, preventing secondary contamination and improving cleaning effectiveness.

[0084] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
