[0022] Embodiment

[0023] Please refer to Figure 1-7 , the present utility model provides the following technical solutions: A handheld vacuum cleaner facilitating the release of a dust cup, including a body 1 and a dust cup 2. The dust cup 2 is detachably connected to the front side of the body 1. A suction motor 8 is provided inside the body 1. A grip portion 14 is provided on one side of the body 1 away from the dust cup 2. A power switch 10 for controlling the operation of the device is provided inside the grip portion 14. The body 1 is also detachably provided with a battery pack 9 for supplying power to the device. A suction port 26 is provided at the front end of the dust cup 2. The suction port 26 is used to connect a dust collection accessory, such as a floor brush, and the inhaled dust is collected into the dust cup 2 through the suction port 26.

[0024] To facilitate the cleaning of the dust cup 2, the dust cup 2 is usually set to be detachably connected to the body 1. In this embodiment, the dust cup 2 is detachably connected to the body 1 through a release button 3. Specifically, the release button 3 is elastically connected to the bottom of the body 1. A pressing portion 31 for operation is formed at the bottom of the release button 3. A locking hook 32 is formed on the side of the release button 3 facing the dust cup 2. A locking portion 321 is formed inside the locking hook 32. The dust cup 2 is correspondingly provided with an annular buckle 21. The dust cup 2 is fixed to the body 1 by clamping the annular buckle 21 into the locking portion 321. A guiding portion 33 is also provided below the locking hook 32 of the release button 3. When the release button 3 moves upward under an external force, the annular buckle 21 disengages from the locking hook 32 to release the dust cup 2. The guiding portion 33 applies at least part of an outward thrust to the annular buckle 21, thereby forming an assisting force for the release of the dust cup 2 to facilitate the removal of the dust cup.

[0025] Furthermore, a limiting cavity 11 is formed at the bottom of the body 1. The release button 3 is abutted in the limiting cavity 11 through a first return spring 4. The limiting cavity 11 plays a role in limiting the movement of the release button 3 to ensure the precise docking of the locking hook 32 and the annular buckle 21.

[0026] Furthermore, the guiding portion 33 is a triangular convex block integrally formed on one side of the release button 3. That is, in this embodiment, the guiding contact surface of the guiding portion 33 is the inclined straight surface of the convex block. Optionally, the guiding contact surface can also be set to be a rounded corner shape.

[0027] Further, on one side of the dust cup 2 facing the body 1, there are a first positioning protrusion 22 and a second positioning protrusion 23. The first positioning protrusion 22 and the second positioning protrusion 23 are arranged vertically along the outer wall of the dust cup with a certain interval. The body 1 is respectively provided with a first positioning groove 12 and a second positioning groove 13, and the two form a plug-in positioning rather than being fixed to each other. This setting not only facilitates the positioning during the installation of the dust cup, but also makes the connection between the dust cup 2 and the body 1 more stable and fitting after being locked.

[0028] Further, on one side of the bottom of the dust cup 2 away from the body 1, a hinged end 24 is formed. The hinged end 24 is hinged with a sealing bottom cover 5. On the outer wall of the other side of the dust cup 2 away from the hinged end 24, there is a locking portion 25. The sealing bottom cover 5 is correspondingly provided with a locking buckle 51. After the locking buckle 51 is engaged with the locking portion 25, the bottom of the dust cup 2 is in a closed state; the body 1 is also movably connected with a bottom cover button 6. The bottom cover button 6 is abutted against the inside of the body 1 by a second return spring 7. The bottom cover button 6 is provided with a driving portion 61 for driving the locking buckle 51 to release, and an operating portion 62 for manual pressing located outside the body. When the operating portion 62 is pressed, the second return spring 7 is compressed, and the driving portion 61 drives the locking buckle 51 downward to disengage from the locking portion 25, and the sealing bottom cover 5 is opened. At this time, without detaching from the body, the dust cup 2 can be emptied. When the operating portion 62 is released, the driving portion 61 is reset under the restoring force of the second return spring 7. Preferably, the locking portion 25 and the locking buckle 51 are engaged inside the annular buckle 21 and do not interfere with the locking hook 32. In this way, while not affecting the locking and releasing of the dust cup 2, the overall structure is relatively compact.

[0029] In this embodiment, the suction motor 8 is located inside the body above the dust cup 2. The suction motor 8 is coaxially arranged with the dust cup 2. Above the holding portion 14, an air outlet passage 15 connecting the suction motor 8 is formed. An air outlet 151 is formed on the outer wall of the air outlet passage 15. Below the holding portion 14, a detachable battery pack 9 for power supply is provided.

[0030] Working principle and usage process of the present utility model: When the power switch 10 is turned on, the battery pack 9 supplies electric energy to the suction motor 8. After the suction motor 8 works, a negative pressure is formed inside the dust cup 2. When the dust-containing air flow enters from the suction port 26, the dust is filtered by the filter screen and retained in the dust cup 2, and the filtered air flow is discharged outward through the air passage formed in the suction motor 8 and the air outlet passage 15.

[0031] Opening method of the sealing bottom cover 5: When the operating portion 62 is pressed, the driving portion 61 drives the locking buckle 51 downward to disengage from the locking portion 25, and the sealing bottom cover 5 is opened. At this time, without detaching from the body, the dust cup 2 can be emptied. When the operating portion 62 is released, the driving portion 61 is reset under the elastic force.

[0032] Removing method of the dust cup 2: As Figure 4As shown, when the annular buckle 21 is clamped in the locking portion 321, the top of the dust cup 2 is hermetically attached to the body 1. At the same time, the first positioning protrusion 22 is inserted into the first positioning groove 12, and the second positioning protrusion 23 is inserted into the second positioning groove 13. At this time, the dust cup 2 is closely attached to and stably connected to the body 1; when the release button 3 is pushed upward through the pressing portion 31, as Figure 5 shown, the annular buckle 21 disengages from the locking portion 321. When it comes into contact with the guiding portion 33, it forms an abutment with the guiding contact surface of the guiding portion 33. Under the action of the force on the guiding contact surface, the lower end of the dust cup 2 is pushed outwards, and the side of the dust cup 2 connected to the body 1 slides downwards, causing the first positioning protrusion 22 to disengage from the first positioning groove 12 and the second positioning protrusion 23 to disengage from the second positioning groove 13, so that the dust cup 2 is completely separated from the body 1. At this time, the dust cup can be easily removed.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
