[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] This embodiment provides a cleaning device, such as Figure 1 As shown, the cleaning device includes a cleaning head, a moving rod 100, a negative pressure assembly, and a dust collection assembly. The moving rod 100 is pivotally connected to the cleaning head, and its hollow interior forms a negative pressure channel 101. The cleaning head has an adsorption port 113, and both the dust collection assembly and the adsorption port 113 are connected to the negative pressure channel 101. When the negative pressure assembly is activated, the cleaning head can draw surrounding debris into the negative pressure channel 101 through the adsorption port 113, and the debris enters the dust collection assembly through the negative pressure channel 101.

[0043] like Figures 1-3 As shown, the cleaning head includes a housing 1 and a roller brush 3. The roller brush 3 is rotatably mounted on the housing 1 and located in front of the suction port 113. The debris rolled up by the roller brush 3 can move to the position of the suction port 113 as the roller brush 3 rotates, thus facilitating its adsorption by the suction port 113 and improving the cleaning effect.

[0044] In this embodiment, the outer casing 1 includes a main body 11 and an end cap 12. The main body 11 is provided with a connecting portion 114, and the end cap 12 is detachably connected to the main body 11. When the end cap 12 is installed on the main body 11, a mounting groove 111 is formed between the end cap 12 and the connecting portion 114. The roller brush 3 is rotatably disposed within the mounting groove 111, that is, the roller brush 3 is rotatably disposed between the connecting portion 114 and the end cap 12. The adsorption port 113 is opened on the surface of the mounting groove 111. The mounting groove 111 enables the negative pressure generated by the adsorption port 113 to be more concentrated, and also prevents dust from scattering and avoids secondary pollution.

[0045] In this embodiment, the cleaning head also includes a drive assembly 4, which includes a mounting frame 41, a drive motor 42, and a transmission component 43. The mounting frame 41 is disposed within the accommodating space, the drive motor 42 is fixedly mounted on the mounting frame 41, and the transmission component 43 is used to drive the drive motor 42 and the roller brush 3. When the user uses the cleaning device, the drive motor 42 starts to drive the roller brush 3 to rotate continuously, ensuring that debris on the bottom surface that the cleaning head has moved over is rolled into the mounting groove 111 by the roller brush 3 and sucked into the suction port 113.

[0046] To facilitate the disassembly of the roller brush 3, the mounting part is provided with a connecting shaft 44, and the transmission component 43 is a transmission belt. The transmission belt is sleeved on the output shaft of the drive motor 42 and the connecting shaft 44 and is tensioned by the output shaft and the connecting shaft 44. One end of the roller brush 3 can be sleeved on the connecting shaft 44 and rotate synchronously with the connecting shaft 44.

[0047] It is worth noting that in addition to some debris and particles, the debris may also contain thin, thread-like objects, such as hair and thread, which can easily get tangled on the surface of the roller brush 3 as it rotates, making them difficult to clean.

[0048] like Figures 2-4 As shown, to solve the above problems, this embodiment also provides a cleaning head. The outer shell 1 of the cleaning head is provided with a receiving space. The receiving space has a cutting slit 112. The cutting component 2 is movably disposed in the receiving space to have a cutting position and a retracted position. When the cutting component 2 is in the cutting position, the cutting component 2 can extend out of the outer shell 1 through the cutting slit 112 to cut the rolled material wrapped around the surface of the roller brush 3. When the cutting component 2 is in the retracted position, the cutting component 2 retracts into the receiving space through the cutting slit 112.

[0049] To prevent the roller brush 3 from getting tangled in easily coiled material, the cutting component 2 can be moved to the cutting position to cut off the coiled material on the surface of the roller brush 3, making it easier for the user to clean the roller brush 3. When the user needs to disassemble or assemble the roller brush 3, the cutting component 2 can be moved to the retracted position, so that the cutting component 2 retracts into the accommodating space and no longer protrudes, thus preventing the cutting component 2 from scratching the operator.

[0050] The cleaning head can cut off the tangled material on the surface of the roller brush 3 to facilitate cleaning by the user, and can also prevent the user from being scratched when disassembling and assembling the roller brush 3, thus improving the user experience.

[0051] In this embodiment, to ensure that the cutting component 2 remains stably in the cutting position during use of the cleaning device, thereby promptly cutting off the rolled material on the surface of the roller brush 3 and allowing the rolled material to be sucked into the suction port 113, when the end cap 12 is installed on the main body 11, the end cap 12 can drive the cutting component 2 from the retracted position to the cutting position. This structure ensures that after the end cap 12 is fastened to the main body 11, the cutting component 2 is in the cutting position, enabling it to cut off the rolled material on the surface of the roller brush 3.

[0052] Preferably, such as Figure 4 and Figure 5 As shown, the end cap 12 is provided with a snap-fit ​​part 121, and the cutting component 2 is provided with a snap-fit ​​groove 212. When the end cap 12 is installed on the main body 11, the snap-fit ​​part 121 is inserted into the snap-fit ​​groove 212 to fix the cutting component 2 in the cutting position. That is to say, the snap-fit ​​part 121 can always keep the cutting component 2 in the cutting position, preventing the cutting component 2 from falling out of the cutting position due to vibration or orientation when the user uses the cleaning device.

[0053] In this embodiment, the latching part 121 has a driving inclined surface 122, and the latching groove 212 has a driven inclined surface 213. During the process of installing the end cap 12 onto the main body 11, the driving inclined surface 122 and the driven inclined surface 213 slide against each other to drive the cutting assembly 2 from the retracted position to the cutting position. This structure combines the structure for driving the cutting assembly 2 to move and the structure for locking the cutting assembly 2 into the latching part 121, thereby greatly reducing the complexity of the structure, saving space, and reducing costs.

[0054] In order to facilitate the linkage between the snap-fit ​​part 121 and the snap-fit ​​groove 212, the outer shell 1 is provided with a notch. When the end cap 12 is installed on the main body 11, the snap-fit ​​part 121 enters the outer shell 1 through the notch and inserts into the snap-fit ​​groove 212.

[0055] Preferably, such as Figure 4 and Figure 6 As shown, the cleaning head also includes a first elastic element 24, one end of which is connected to the housing 1, and the other end of which is connected to the cutting assembly 2. The first elastic element 24 is configured to drive the cutting assembly 2 from the cutting position to the retracted position. When the user removes the end cap 12 and the roller brush 3, the first elastic element 24 can drive the cutting assembly 2 back to the retracted position, so that the cutting assembly 2 retracts into the receiving space and avoids cutting the user.

[0056] like Figures 6-8As shown, the cutting assembly 2 includes a fixed cutting member 22 and a movable cutting member 23. The fixed cutting member 22 includes a first cutting tooth 221, and the movable cutting member 23 includes a second cutting tooth 233. The movable cutting member 23 can reciprocate relative to the fixed cutting member 22 so that the first cutting tooth 221 and the second cutting tooth 233 cut the wound material. When the movable cutting member 23 and the fixed cutting member 22 reciprocate relative to each other, the first cutting tooth 221 and the second cutting tooth 233 move crosswise, which can shear the wound material, improving cutting efficiency and cutting effect.

[0057] It is worth noting that the fixed cutting component 22 is provided with multiple first cutting teeth 221 at intervals, and the moving cutting machine is provided with multiple second cutting teeth 233 at intervals, so that the cutting range of the cutting component 2 can cover the entire axial dimension of the roller brush 3.

[0058] To ensure the stability of the movable cutting component 23 and the fixed cutting component 22, the cutting assembly 2 also includes a bracket 21. The bracket 21 is disposed within the accommodating space. The fixed cutting component 22 is fixedly connected to the bracket 21, and the movable cutting component 23 is movably connected to the bracket 21. The cutting assembly 2 also includes a second elastic element 25, which is configured to drive the bracket 21 to move towards the end cap 12. A locking groove 212 is disposed on the bracket 21. This structure provides the bracket 21 with more degrees of freedom of movement, so that the user will not damage the bracket 21 when fastening the end cap 12 to the main body 11. It also ensures that the locking groove 212 of the bracket 21 and the locking part 121 of the end cap 12 stably abut and lock, thus ensuring the stability of the cutting assembly 2.

[0059] like Figure 6 and Figure 9 As shown, the cutting assembly 2 also includes a driving component 26 and a driving disk 27. The driving component 26 is connected to the driving disk 27 in a transmission manner. The driving disk 27 is eccentrically provided with a driving shaft 271. The movable cutting component 23 has a driving hole 231. The driving shaft 271 is disposed in the driving hole 231 to drive the movable cutting component 23 to reciprocate relative to the fixed cutting component 22. When the driving component 26 drives the driving disk 27 to rotate, the eccentric shaft on the driving disk 27 drives the movable cutting component 23 to reciprocate relative to the fixed cutting component 22 through the inner wall of the driving hole 231, thereby converting the rotational motion of the driving component 26 into the linear reciprocating motion of the movable cutting component 23.

[0060] Specifically, the drive hole 231 has two drive inner walls 232 spaced apart. The distance between the two drive inner walls 232 is less than the rotation diameter of the eccentric shaft. Therefore, when the eccentric shaft rotates with the drive disk 27, the eccentric shaft can alternately abut against the two drive inner walls 232, thereby causing the moving cutting machine to reciprocate.

[0061] To improve the stability between the movable cutting component 23 and the fixed cutting component 22, the bracket 21 is provided with a guide post 211, the fixed cutting component 22 is provided with a first guide hole 222, and the movable cutting component 23 is provided with a second guide hole 234. The guide post 211 passes through the first guide hole 222 and the second guide hole 234 to guide the movable cutting component 23 and the fixed cutting component 22. By using the guide post 211 passing through the first guide hole 222 and the second guide hole 234, the initial positions of the fixed cutting component 22 and the movable cutting component 23 can be unified, and the movement of the movable cutting component 23 can also be guided.

[0062] Preferably, the cutting assembly 2 further includes a sealing strip 28, which is disposed on the movable cutting member 23 and configured to seal the gap between the cutting assembly 2 and the cutting slit 112. The sealing strip 28 can prevent dust and particles entering the mounting groove 111 from entering the interior of the housing 1 through the gap between the cutting assembly 2 and the cutting slit 112, effectively protecting the electronic components inside the housing 1 and extending their service life.

[0063] In some embodiments, the sealing strip 28 is disposed on the fixed cutting member 22. Alternatively, both the fixed cutting member 22 and the movable cutting member 23 are provided with sealing strips 28 to further improve the sealing effect.

[0064] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
