[0030] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0031] The following is for reference. Figures 1-9 This invention describes a dust collection device according to an embodiment of the present invention.

[0032] like Figures 1-3 As shown, the vacuum cleaner includes a main unit 1, a floor brush 2, and a rod assembly 3, with the rod assembly 3 connected between the main unit 1 and the floor brush 2. The rod assembly 3 includes a telescopic part 31 and a bending part 32 connected together. The bending part 32 has a straightened state and a bent state. In the straightened state, the bending part 32 and the telescopic part 31 extend along the same straight line. In the bent state, the bending part 32 and the telescopic part 31 form an angle.

[0033] Specifically, with the bent portion 32 in its straight state, adjusting the length of the telescopic portion 31 allows for convenient use by users of different heights and to accommodate varying suction distances. With the bent portion 32 in its bent state, when cleaning areas such as under sofas or beds, users do not need to bend over; adjusting the length of the telescopic portion 31 allows for a deeper and more comprehensive cleaning, improving the flexibility of the vacuum cleaner and enhancing user comfort.

[0034] The working principle of the vacuum cleaner is as follows: When the main unit 1 is working, the floor brush 2 moves on the floor to be cleaned and sucks in the dust-laden airflow. This airflow is then guided into the main unit 1 through the airflow channel inside the rod assembly 3. The main unit 1 contains a dust collection device, such as a dust cup, an air-ash separator, a suction motor, and a battery pack, all of which are not shown in the figure. The rod assembly 3 transmits force between the main unit 1 and the floor brush 2. The user operates the main unit 1, which transmits the force to the floor brush 2 via the rod assembly 3, thus performing the cleaning operation. The vacuum cleaner also includes a handle 4, which is connected to the rod assembly 3. The main unit 1 is mounted on the handle 4, and the user holds the handle 4 to perform the cleaning operation.

[0035] According to the present invention, the vacuum cleaner combines the telescopic part 31 and the bending part 32 together, replacing the solution of using two bending modules in the prior art. The rod assembly 3 is more stable when used in the straight state, so that the vacuum cleaner has both the flexibility of bending and the stability when used in the straight state. This allows users to easily clean the deep areas under furniture and is convenient for users of different heights, thus improving the ease of use of the vacuum cleaner.

[0036] According to some embodiments of this utility model, such as Figures 1-8 In the embodiment shown, the telescopic part 31 is located between the bending part 32 and the main unit 1, and the bending part 32 is connected to the floor brush 2.

[0037] In other words, the sequence of connection from one end of the main unit 1 to the other end of the floor brush 2 is: main unit 1, telescopic part 31, bending part 32, floor brush 2. Thus, the telescopic part 31 is set at the end closer to the main unit 1, that is, the end held by the user, so that the length of the rod assembly 3 can be adjusted, making it convenient for people of different heights to use.

[0038] According to some embodiments of the present invention, the telescopic part 31 is located between the bending part 32 and the floor brush 2, and the bending part 32 is connected to the main unit 1.

[0039] In other words, the sequence of connection from one end of the main unit 1 to the other end of the floor brush 2 is: main unit 1, bending part 32, telescopic part 31, floor brush 2. In this way, by setting the telescopic part 31 closer to the end of the floor brush 2, the floor brush 2 can be further extended into the bottom of the furniture to clean deeper areas by adjusting the length of the telescopic part 31.

[0040] In addition, the connection between the main unit 1, the bending part 32, the telescopic part 31 and the floor brush 2 is set to be detachable, so that the user can change the connection position of the telescopic part 31 according to the usage needs, thereby improving the flexibility of the vacuum cleaner.

[0041] According to some embodiments of this utility model, such as Figure 2 As shown, the telescopic part 31 includes a first connecting pipe 3101 and a second connecting pipe 3102 connected to the first connecting pipe 3101 and slidable relative to the first connecting pipe 3101. The bending part 32 is provided at the end of the first connecting pipe 3101 or the second connecting pipe 3102 so that the telescopic part 31 is connected to the floor brush 2 or the main unit 1 through the bending part 32.

[0042] In other words, the telescopic part 31 and the bending part 32 are integrated and located on the same rod assembly 3. Thus, when the telescopic part 31 is in the retracted state, the bending part 32 is connected to one end of the telescopic part 31. Compared with setting the telescopic part 31 and the bending part 32 separately on two rod assemblies, the number of accessories is reduced and the space required for storage is smaller. In addition, users only need to install one rod assembly to realize the telescopic and bending functions at the same time, thus optimizing the user experience.

[0043] According to some embodiments of the present invention, the bending portion 32 includes: a first hinge 3201 and a second hinge 3202, the second hinge 3202 being pivotally connected to the first hinge 3201, the first hinge 3201 being closer to one end of the floor brush 2 than the second hinge 3202, the first hinge 3201 and the second hinge 3202 being connected by a flexible tube 3203, in the bent state, the first hinge 3201 and the second hinge 3202 being pivotally relative to each other, and the flexible tube 3203 being deformed, in the straight state, the first hinge 3201 and the second hinge 3202 being in the same straight line.

[0044] Specifically, when the bent portion 32 is in a bent state, the first hinge 3201 and the second hinge 3202 can pivot relative to each other, causing the flexible tube 3203 to be exposed between the first hinge 3201 and the second hinge 3202 and to undergo bending deformation to achieve different degrees of curvature. When the bent portion 32 is in a straight state, the first hinge 3201, the second hinge 3202, and the telescopic portion 31 are aligned in a straight line.

[0045] The first hinge 3201 and the second hinge 3202 can be bent between 0° and 180° to accommodate cleaning operations in confined areas. The airflow of the flexible tube 3203 connects the first hinge 3201 and the second hinge 3202 and forms part of the airflow channel of the rod assembly 3. In this example, the flexible tube 3203 may be a telescopic hose.

[0046] According to some embodiments of the present invention, the bending portion 32 further includes a locking arm 3204 and a locking portion 3205. The locking portion 3205 is provided on the outer wall of the first hinge member 3201, and the locking arm 3204 is provided on the outer wall of the second hinge member 3202. The locking arm 3204 selectively engages with the locking portion 3205 for locking.

[0047] With this configuration, since the first hinge 3201 is closer to the end of the floor brush 2 than the second hinge 3202, the second hinge 3202 can often bend forward relative to the first hinge 3201 during user use. Therefore, a locking arm 3204 is provided on the outer wall of the second hinge 3202, and a locking part 3205 is provided on the outer wall of the first hinge 3201. The user rotates the second hinge 3202 to be in a straight line with the first hinge 3201 by acting on the rod assembly 3 above the second hinge 3202 and the main unit 1. Then, the locking arm 3204 and the locking part 3205 engage in a locking engagement, ensuring the stability of the bent part 32 when it is in a straight state. When the bent part 32 needs to be bent, the locking arm 3204 engages with the locking part 3205 to lock, allowing the second hinge 3202 to rotate relative to the first hinge 3201.

[0048] According to some embodiments of the present invention, one end of the locking arm 3204 has a pressing portion 3206, and the other end has a locking portion 3207. Furthermore, the bending portion 32 also includes a reset member 3208, which is disposed below the pressing portion 3206 to reset the pressing portion 3206 and to lock the locking portion 3207 and the locking portion 3205 in a locked engagement.

[0049] Specifically, see Figure 6 and Figure 8 As shown, when the bending part 32 needs to be bent, the user presses the pressing part 3206, causing the locking part 3207 to separate from the locking part 3205. At this time, the first hinge 3201 and the second hinge 3202 can rotate relative to each other. When it needs to be restored, it rotates in the opposite direction to the bending direction. When the locking part 3205 moves to lock with the locking part 3207, the reset part 3208 returns to its original position, causing the pressing part 3206 to reset. It also provides a force for the locking part 3207 to abut against the locking part 3205, thereby completing the locking engagement between the locking part 3207 and the locking part 3205. At this time, the bending part 32 is in a straight state and can transmit the force to the floor brush 2 together with the telescopic part 31.

[0050] In this embodiment, the locking part 3205 is a protruding structure. During rotation in the direction opposite to the bending direction, the inclined surface on the protruding structure can push up the locking part 3207 and move it to the locking position. After the protruding structure moves into place, the reset member 3208 returns to its original position. In this embodiment, the reset member 3208 is a reset spring.

[0051] According to some embodiments of the present invention, the bending part 32 further includes a protective cover 3209, which is arranged around the outer peripheral surface of the locking arm 3204, and the inner wall of the locking arm 3204 is locked in place with the locking part 3205.

[0052] Reference Figure 4 and Figure 6 As shown, a protective cover 3209 is provided around the outer periphery of the locking arm 3204 to prevent the locking arm 3204 from being accidentally touched or damaged by collision during use. At the same time, it reduces the relative shaking between the locking part 3205 and the locking arm 3204 in the straightened state and improves the stability in the straightened state.

[0053] According to some embodiments of the present invention, the bending portion 32 further includes a support wheel 3210, which is disposed on the outer wall of the first hinge member 3201 and is used to support the bending portion 32.

[0054] Reference Figure 4 and Figure 6 As shown, a support wheel 3210 is provided on the first hinge 3201. When the bent portion 32 is used, the support wheel 3210 can provide a certain support, reducing the user's hand burden, and at the same time preventing the first hinge 3201 from directly rubbing against the ground, scratching the ground, or causing wear to the first hinge 3201. The support wheel 3210 and the locking arm 3204 are located on the same side of the rod assembly 3, specifically on the rear wall of the rod assembly 3.

[0055] According to some embodiments of the present invention, the outer walls of the first hinge member 3201 and the second hinge member 3202 are both provided with abutting planes 3211. When the first hinge member 3201 and the second hinge member 3202 pivot relative to each other to the maximum bending degree, the first hinge member 3201 and the second hinge member 3202 abut against each other through the abutting planes 3211.

[0056] Reference Figure 5 and Figure 9 As shown, when the bending portion 32 is bent to 180°, the first hinge 3201 and the second hinge 3202 can abut against each other through the abutment plane 3211, thereby avoiding excessive bending. Compared with some bending tubes in the prior art that have a limiting protrusion or limiting rib at the pivot, it is less prone to breakage and damage.

[0057] According to some embodiments of the present invention, the first hinge member 3201 includes: a first sleeve 3212 and a first seal 3213, the first seal 3213 being connected inside the first sleeve 3212; the second hinge member 3202 includes: a second sleeve 3214 and a second seal 3215, the second seal 3215 being connected inside the second sleeve 3214; the first sleeve 3212 and the second sleeve 3214 are pivotally connected; a flexible tube 3203 is provided inside the space between the first sleeve 3212 and the second sleeve 3214; one end of the flexible tube 3203 is connected to the first seal 3213, and the other end is connected to the second seal 3215.

[0058] Reference Figure 7 As shown, the first sleeve 3212 and the second sleeve 3214 are pivotally connected. Inside them, the first seal 3213 is used to seal one end of the flexible tube 3203, and the second seal 3215 is used to seal the other end of the flexible tube 3203, so that the suction airflow passes through the airflow channel of the rod assembly 3 formed by the first seal 3213, the flexible tube 3203 and the second seal 3215.

[0059] According to some embodiments of this utility model, such as Figure 2 As shown, the second connecting pipe 3102 is provided with a plurality of spaced-apart locking holes 3103 along its length, and the first connecting pipe 3101 is provided with a retractable locking block. The length of the telescopic part 31 can be adjusted by the locking block and the locking holes 3103.

[0060] Compared with the prior art, the vacuum cleaner of this utility model combines the telescopic part 31 and the bending part 32 together, replacing the solution of using two bending modules in the prior art. The rod assembly 3 is more stable when used in the straight state, so that the vacuum cleaner has both the flexibility of bending and the stability when used in the straight state. It allows users to easily clean the deep areas under furniture and is convenient for users of different heights.
