[0029] The following detailed description illustrates the specific implementation method:

[0030] The reference numerals in the accompanying drawings include: housing 1, dust cup 2, drive unit 3, grip unit 4, control unit 5, noise reduction assembly 6, end cap 7, filter assembly 8, cover 9, pressing part 10, locking block 11, locking plate 12, front cover 13, rear cover 14, top rod 15, spring 16, top block 17, lowering block 18, top shell 19, bottom shell 20, display screen 21, control board 22, protective cover 23, and push button switch 24.

[0031] As attached Figure 1-7 As shown in the figure, this embodiment illustrates a handheld vacuum cleaner, including a housing 1, a dust cup 2, a drive unit 3, a grip unit 4, and a control unit 5. The dust cup 2 is located at the front end of the housing 1, the drive unit 3 is located at the rear end of the housing 1, the control unit 5 is located above the drive unit 3, and the grip unit 4 is located at the rear end of the housing 1. A detachable noise reduction component 6 is located at the rear end of the drive unit 3. The noise reduction component 6 includes a detachably connected end cap 7 and a filter assembly 8, which is wrapped around the rear end of the drive unit 3.

[0032] The working principle of the handheld vacuum cleaner in this embodiment is as follows: by pressing the switch on the drive unit 3, the drive unit 3 is started to work. The motor inside the drive unit 3 rotates to generate a negative pressure environment, and draws in dust and impurities from the outside through the suction channel at the front end of the housing 1. The air carrying the dust and impurities enters the housing 1 and is then filtered by the dust cup 2, and finally discharged through the air outlet of the drive unit 3.

[0033] In this embodiment, a filter assembly 8 is installed at the rear end of the drive unit 3 to absorb some of the noise from the motor of the drive unit 3, thereby reducing the noise transmitted to the outside. At the same time, the filter assembly 8 also acts as a final layer of filtration, which can absorb some odors.

[0034] Specifically, the top and bottom of the end cap 7 are snapped into the drive unit 3 and the housing 1, respectively. The end cap 7 achieves quick installation or removal from the drive unit 3 and the housing 1 through the snap-fit ​​connection, which facilitates cleaning of the filter assembly 8.

[0035] The end cap 7 includes a cover body 9, which has a hollow structure. Pressing parts 10 are provided on both sides of the cover body 9, a locking block 11 is provided at the bottom inside the cover body 9, and a locking plate 12 is provided in the upper middle part of the cover body 9. The locking block 11 engages with the housing 1, and the locking plate 12 engages with the driving part 3. The pressing parts 10 on both sides are linked to the locking block 11 and the locking plate 12 respectively. The user can press the pressing parts 10 to disengage the locking block 11 and the locking plate 12 from the housing 1 and the driving part 3 respectively.

[0036] Specifically, the cover 9 includes a front cover 13 and a rear cover 14 connected by screws, a retaining plate 12 is disposed between the front cover 13 and the rear cover 14, a pressing part 10 is disposed on both sides of the rear cover 14, and a retaining block 11 is disposed at the bottom of the rear cover 14.

[0037] The pressing part 10 has a push rod 15 at its inner bottom, and the locking block 11 has inclined surfaces on both sides corresponding to the push rod 15. The push rod 15 and the inclined surfaces of the locking block 11 are linked, and a spring 16 is provided between the locking block 11 and the rear cover 14. Specifically, when the end cover 7 needs to be removed, when the user presses the pressing part 10, the pressing part 10 drives the push rod 15 to move inward. The push rod 15 pushes the locking block 11 upward through the inclined surfaces of the locking block 11, causing the locking block 11 to disengage from the housing 1. After disassembly, the locking block 11 returns to its original position downward under the action of the spring 16.

[0038] The pressing part 10 has a top block 17 at its top, and a descending block 18 on the locking plate 12. The descending block 18 has inclined surfaces on both sides, which engage with the top block 17. The inclined surfaces of the top block 17 and the descending block 18 are linked. A spring 16 is installed between the locking plate 12 and the rear cover 14. When the end cover 7 needs to be removed, the user presses the pressing part 10, which causes the top block 17 to move inward. The top block 17 pushes the locking plate 12 downward through the inclined surfaces of the descending block 18, causing the locking plate 12 to disengage from the drive part 3. After disassembly, the locking plate 12 returns to its original position under the action of the spring 16.

[0039] It is understood that corresponding locking holes (not shown in the figure) are provided on the housing 1 and the drive unit 3 for the locking block 11 and the locking plate 12 to engage.

[0040] In the above embodiment, the filter assembly 8 is rotatably snapped to the end cap 7.

[0041] Specifically, the drive unit 3 includes a top shell 19 and a bottom shell 20. The bottom shell 20 is screwed to the housing 1, and the top shell 19 is snapped to the bottom shell 20. The control unit 5 is disposed on the top shell 19.

[0042] The control unit 5 includes a display screen 21, a control board 22, a protective cover 23, and a push-button switch 24. The control board 22 and display screen 21 are fixed to the control unit 5 with screws, and the protective cover 23 is snap-fitted onto the control unit 5. The push-button switch 24 and display screen 21 are connected to the control board 22 via signal transmission.

[0043] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
