[0024] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. And the following definitions are provided: Figure 1 The direction from left to right shown on the paper is the same as the direction from front to back in this embodiment.

[0025] See Figures 1 to 4 As shown in the figure, the handheld vacuum cleaner provided in this embodiment includes a vacuum cleaner body 1 and an arc-shaped battery pack 4. The vacuum cleaner body 1 has a vertical dustbin 2 and a handle 3 arranged in the rear direction of the dustbin 2. An arc-shaped mounting cavity for arranging the arc-shaped battery pack 4 is formed between the dustbin 2 and the handle 3. The arc-shaped battery pack 4 is inserted into the arc-shaped mounting cavity from bottom to top in an arc direction.

[0026] Based on the above technical solution, the handheld vacuum cleaner includes a vacuum cleaner body 1 and an arc-shaped battery pack 4. The vacuum cleaner body 1 has a dustbin 2, a handle 3, and an arc-shaped mounting cavity. The arc-shaped battery pack 4 is inserted into the arc-shaped mounting cavity in an arc direction, making the overall structure simpler and the layout more reasonable. The design of the arc-shaped battery pack 4 and the arc-shaped mounting cavity makes the center of the whole machine tilted to the rear side and makes the battery pack less likely to fall out downwards, making the structure more stable.

[0027] In a preferred embodiment, the lower end of the outer wall of the arc-shaped mounting cavity has a notch, and the lower side of the battery pack forms a charging port 6. In the assembled state, the charging port 6 is exposed through the notch to allow charging of the battery pack. This eliminates the need for additional charging wiring on the vacuum cleaner body 1, resulting in a cleaner overall wiring structure.

[0028] As a further preferred embodiment, combined with Figures 2 to 4 As shown, the back 5 of the curved battery pack 4 is generally curved and bulges backward. Figure 2 As shown in the diagram, coordinate line X is the line connecting the planes containing the lower surface of the vacuum cleaner body 1, and coordinate line Y is an arc with its origin at a point away from the vacuum cleaner body 1. The arc-shaped battery pack 4 and the arc-shaped mounting cavity are generally located on the extension line of this arc. During assembly, the arc-shaped battery pack 4 is inserted into the arc-shaped mounting cavity along the extension direction of this arc (i.e., coordinate line Y). Due to the large overall weight of the battery pack, the weight of the assembled vacuum cleaner tilts away from the dustbin 2.

[0029] As a further preferred embodiment, from a side view, the arc-shaped battery pack 4 has battery cells arranged in an arc shape. The arc-shaped battery pack structure can accommodate more battery cells at the same height. Similarly, with the same number of battery cells, the arc-shaped battery pack 4 can have a smaller vertical height than the straight battery pack, thus requiring less space between the dustbin 2 and the handle 3.

[0030] As a further preferred embodiment, the lower end of the back 5 of the arc-shaped battery pack 4 also has a notch, and an elastic buckle structure 7 is provided in the notch. The arc-shaped mounting cavity has a slot that is adapted to the elastic buckle structure 7. In the assembled state, the buckle of the elastic buckle structure 7 extends at least partially backward from the arc surface where the back 5 of the arc-shaped battery pack 4 is located and engages with the slot, so that the arc-shaped battery pack 4 is confined in the arc-shaped mounting cavity.

[0031] In a preferred embodiment, the arc-shaped mounting cavity has an opening 11 on the side facing the handle 3. In the assembled state, at least part of the back 5 of the arc-shaped battery pack 4 protrudes through the opening 11, and the lower edge of the opening 11 forms a slot. The snap fastener of the elastic snap fastener structure 7 moves in a direction away from the arc-shaped battery pack 4 under the action of the internal elastic element to hold the lower edge of the opening 11, and can release the locking state between the snap fastener and the slot when the snap fastener is pressed. Thus, the assembly structure is simpler.

[0032] As a further preferred embodiment, the front end face of the arc-shaped battery pack 4 has an electrical interface 9, and two upwardly open guiding positioning grooves 8 are mirror-symmetrically formed on both sides of the electrical interface 9, and the arc-shaped mounting cavity has guiding ribs in an equal number and in a position opposite to the guiding positioning grooves 8, so that the electrical interface 9 can be accurately connected to the communication end in the accommodating cavity during assembly.

[0033] As a further preferred embodiment, the lower front end and both sides of the arc-shaped battery pack 4 are outwardly raised to form a base structure 10, and the base structure 10 is located outside the arc-shaped mounting cavity in the assembled state, and supports the dust collector main body 1 together with the bottom surface of the dust bucket 2 and the lower end of the handle 3, so that the handheld dust collector can be placed on the ground or a table. Further, the charging port 6 is formed on the base structure 10. Further, the upper edge of the both side portions of the base structure 10 (i.e. the portion having the charging port 6 and the other side portion opposite thereto) is an arc surface with a front high and rear low. Correspondingly, the lower edge of the notch is also an arc surface with a front high and rear low.

[0034] In addition, the internal structure of the battery pack is well known to those skilled in the art, including charging modules, circuit boards, and cell layouts, and the internal structure of the dust collector is also well known to those skilled in the art, and is not the main innovation of the present application, so it is omitted here.

[0035] The above description is only the preferred embodiment of the present application, which is only illustrative but not limiting. It is understood by those skilled in the art that many changes, modifications, or even equivalents can be made within the spirit and scope of the present application, but all will fall within the protection scope of the present application.
