For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The vacuum cleaner 100 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0037] like Figure 1 , Figure 2 , Figure 4 As shown, a vacuum cleaner 100 according to an embodiment of the present invention includes: a main body 10, a dust cup 20, a display module 30, and an unlocking component 40.

[0038] A limiting groove 101 is provided on the main body 10, and a stopper 102 is provided on the main body 10; the dust cup 20 is suitable for fitting on the main body 10, and the side of the dust cup 20 stops on the stopper 102, and the stopper 102 plays a role in supporting the dust cup 20. The dust cup 20 can be installed on the main body 10 in conjunction with the unlocking assembly 40.

[0039] The display module 30 is arranged on the main body 10, and the display module 30 moves between a starting position and an ending position. A gap is formed between the display module 30 at the starting position and the side of the dust cup 20, and the display module 30 at the ending position does not overlap with the area formed by the bottom and top of the dust cup 20.

[0040] The unlocking assembly 40 is located in the gap, which can hide the unlocking assembly 40, making the appearance of the vacuum cleaner 100 more beautiful and simple. The unlocking assembly 40 is connected to the dust cup 20, and is used for installing and removing the dust cup 20 on the main body 10.

[0041] The unlocking assembly 40 includes a movable member 41, and the movable member 41 moves between a locking position and a releasing position, wherein the movable member 41 extends into the limiting groove 101 in the locking position, and extends out of the limiting groove 101 in the releasing position. Specifically, the dust cup 20 is matched with the main body 10, and when the movable member 41 extends into the limiting groove 101, the dust cup 20 is installed on the main body 10 under the joint action of the stopper 102; when the movable member 41 extends out of the limiting groove 101, the stopper 102 alone cannot completely fix the dust cup 20, so that the dust cup 20 can be removed from the main body 10.

[0042] It should be noted that in existing vacuum cleaners, the display module is mostly located on the side of the dust cup, so that the display module seriously affects the installation and removal of the dust cup. In the present invention, when the display module 30 is movable to the end position, it can be separated from the spatial area formed by the bottom and top of the dust cup 20, so as to expose the unlocking component 40, which is convenient for the user to operate the unlocking component 40. In addition, when the display module 30 is at the end position, the side of the dust cup 20 is not blocked by the display module 30, which is convenient for the dust cup 20 to be installed on the main body 10, or to be removed from the main body 10.

[0043] According to the vacuum cleaner 100 of the embodiment of the present invention, by arranging the unlocking component 40 in the gap between the display module 30 and the dust cup 20, the overall structure of the vacuum cleaner 100 is more compact and the appearance is more simple and beautiful. By moving the display module 30 on the main body 10, the unlocking component 40 can be exposed, and the side of the dust cup 20 is free of obstructions, which facilitates the installation and removal of the dust cup 20 on the main body 10.

[0044] In some embodiments, such as Figure 3 As shown, the unlocking assembly 40 further includes: a housing 42 and an elastic member (not shown). A cavity 421 is formed in the housing 42, and the movable member 41 is located in the cavity 421. The movable member 41 can extend or retract into the housing 42 at least partially along the axis direction of the dust cup 20. For example, the movable member 41 can be inserted into the limiting groove 101 after extending upward from the housing 42, thereby fixing the dust cup 20, and the movable member 41 can be disengaged from the limiting groove 101 after retracting downward from the housing 42, thereby unlocking the dust cup 20.

[0045] The elastic member is arranged between the movable member 41 and the housing 42 to keep the movable member 41 moving toward the limiting groove 101. That is, under the action of the elastic member, the movable member 41 always remains extended into the limiting groove 101 to fix the dust cup 20 on the main body 10.

[0046] Specifically, the elastic member is a spring, which has a simple structure and is easy to install and use. Of course, the elastic member is not limited to this, and can also be parts such as an elastic sleeve, which will not be described in detail here.

[0047] Specifically, if Figure 3 As shown, a first exit hole 422 is provided on the housing 42 , and a portion of the movable member 41 is fitted in the first exit hole 422 to enable the movable member 41 to extend out of or retract into the housing 42 .

[0048] Optional, such as Figure 3 As shown, the unlocking assembly 40 also includes: an unlocking member 44, which can be extended or retracted on the housing 42, and the unlocking member 44 has a triggering portion 441 located in the cavity 421, and the triggering portion 441 stops on the movable member 41 to enable the movable member 41 to move between the locked position and the released position. For example, the unlocking member 44 can be used as a button to start the unlocking assembly 40. Since the unlocking member 44 can extend out of the housing 42, the movable member 41 can be moved from the locked position to the released position by pressing the unlocking member 44, thereby unlocking the dust cup 20. When the unlocking member 44 loses its pressure, the movable member 41 can be guaranteed to return to the locked position under the action of the elastic member, so that the dust cup 20 can be fixed again.

[0049] Specifically, if Figure 3 As shown, the housing 42 is provided with a second hole 423 , and the unlocking member 44 is fitted on the second hole 423 . The unlocking member 44 is triggered by pressing a portion of the unlocking member 44 outside the second hole 423 .

[0050] Optional, such as Figure 3 As shown, there are two unlocking members 44, and the two unlocking members 44 are arranged on opposite sides of the housing 42. In this way, it is convenient for the user to operate with two fingers at the same time, which is more convenient to use.

[0051] Optional, such as Figure 3As shown, the two trigger parts 441 are formed with a first inclined surface 4411, and the movable part 41 is formed with a second inclined surface 411 at the positions corresponding to the two first inclined surfaces 4411, and the second inclined surface 411 and the first inclined surface 4411 are mutually abutted. For example, the movable part 41 extends in or out in the vertical direction, and the two trigger parts 441 extend or retract in the horizontal direction on the housing 42. When the trigger part 441 is pressed to retract into the housing 42, the first inclined surface 4411 and the second inclined surface 411 act to push the movable part 41 downward, thereby disengaging from the limiting groove 101; when the pressure on the trigger part 441 disappears, the movable part 41 can move vertically upward again under the action of the elastic part, and the second inclined surface 411 and the first inclined surface 4411 act to reset the trigger part 441 to extend out of the housing 42. The movement form is simple and the operation is convenient.

[0052] In some embodiments, such as Figure 3 As shown, a guide mechanism 43 is provided between the movable part 41 and the housing 42 , and the guide mechanism 43 enables the movable part 41 to move along the axial direction of the dust cup 20 .

[0053] Specifically, Figure 3 As shown, the guide mechanism 43 includes a slide rail 431 arranged in the cavity 421 and a slide groove (not shown) arranged on the movable part 41. The slide rail 431 and the slide groove cooperate to realize the extension or retraction of the movable part 41 on the housing 42, ensuring the reliable movement of the movable part 41.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the main body 10 includes: a handle assembly 11; a display module 30 is circular, and the display module 30 is pivotally arranged on the handle assembly 11, that is, the display module 30 moves from the initial position to the terminal position by rotating. With this rotation method, the operation is simple and convenient. The part where the handle assembly 11 is connected to the main body 10 forms an arc portion 12, and the housing 42 is arc-shaped. The housing 42 and the arc portion 12 together form a circular block, and the diameter of the circular block is equal to that of the display module 30. It can be understood that the outline of the display module 30 is the same as the outline formed by the unlocking assembly 40 and the arc portion 12, and the two overlap each other, which can better hide the unlocking assembly 40, and the appearance is more beautiful and simple.

[0055] In other examples, the display module 30 may also be slidably disposed on the handle assembly 11. For example, the display module 30 slides upward to the end position, at which time the unlocking assembly 40 may also be exposed, thereby enabling the removal and installation of the dust cup 20.

[0056] Optional, such as Figure 1 As shown, a mounting hole 121 is provided on the arc portion 12 , and a rotating shaft 301 is provided on the display module 30 , and the rotating shaft 301 is fitted in the mounting hole 121 .

[0057] Optionally, the rotation angle of the display module 30 on the arc portion 12 does not exceed 180 degrees. Within this angle range, the display module 30 can completely separate from the area formed by the bottom and top of the dust cup 20 after rotation, ensuring that there is no obstruction on the side of the dust cup 20.

[0058] In some embodiments, such as Figure 2 As shown, the main body 10 has a first mating surface 103, and the limiting groove 101 is formed on the first mating surface 103. The top of the dust cup 20 is mated on the first mating surface 103. The first mating surface 103 can play a role in positioning the top of the dust cup 20 to ensure reliable installation between the dust cup 20 and the main body 10.

[0059] In some embodiments, such as Figure 1 and Figure 2 As shown, the main body 10 has a second mating surface 104, the stopper 102 is arranged on the second mating surface 104, and the side of the dust cup 20 is mated on the second mating surface 104. The second mating surface 104 can play a role in positioning the side of the dust cup 20, and work together with the first mating surface 103 to further ensure the reliable installation of the dust cup 20 and the main body 10. Specifically, when the dust cup 20 is installed, the side of the dust cup 20 stops on the second mating surface 104, the top of the dust cup 20 stops on the first mating surface 103, and then is supported by the stopper 102 to prevent it from moving downward, and finally the dust cup 20 is locked by the unlocking component 40.

[0060] Specifically, if Figure 1 As shown, the second mating surface 104 is an arc-shaped surface, which is mated on the side of the dust cup 20, thereby limiting the movement of the dust cup 20 in the horizontal direction.

[0061] Specifically, if Figure 2 As shown, a positioning groove 105 is provided on the second mating surface 104, and a positioning protrusion 202 is provided on the side of the dust cup 20. The positioning protrusion 202 and the positioning groove 105 cooperate with each other to better limit the movement of the dust cup 20 in the horizontal direction.

[0062] Optional, such as Figure 2As shown, the stopper 102 is formed as a hook, and a slot (not shown) or a matching hook 201 that matches the hook is provided on the side of the dust cup 20. For example, the stopper 102 is a hook, and a slot is provided on the side of the dust cup 20. In this case, the hook can be elastically movable along the vertical direction on the second matching surface 104. When the dust cup 20 is installed, it moves along the horizontal direction and matches the second matching surface 104. The hook elastically moves upward and then resets, and finally engages in the slot, which can hold up the side of the dust cup 20 and prevent the dust cup 20 from moving downward. Alternatively, the stopper 102 is a hook, and a mating hook 201 is provided on the side of the dust cup 20. In this case, the mating hook 201 can be elastically movable on the dust cup 20 in the vertical direction. When the dust cup 20 is installed, it is mated with the second mating surface 104 in the horizontal direction. The mating hook 201 moves upward and then resets, and finally engages with the hook. The two cooperate with each other to support the dust cup 20 and prevent the dust cup 20 from moving downward.

[0063] In some embodiments, the display module 30 is a power display module of the vacuum cleaner 100. For example, the display module 30 can be a power display screen that displays the power of the vacuum cleaner 100 in real time. Of course, the display module 30 can also be used to display actual information of the vacuum cleaner 100, such as working time, working mode, etc.

[0064] In some embodiments, the unlocking assembly 40 is fixed to the dust cup 20 by screws and buckles, so that the unlocking assembly 40 and the dust cup 20 can be detachable, which is convenient for replacement and maintenance and helps to extend the service life.
