Description

TECHNICAL FIELD

[0001] The present application relates to the field of cleaning appliances, in particular, to a cleaning device. BACKGROUND

[0002] The current market floor brush cleaning head generally adopts a hard connection mode with the main machine. This design limits the flexibility and application range of the cleaning tool. Specifically, since the floor brush cleaning head is hard connected with the main machine, the direction control of the main machine on the cleaning head is relatively single, mainly limited to forward and backward movement. This linear operation mode cannot face complex and variable cleaning environments.

[0003] In actual application, cleaning work often needs to be carried out at multiple angles and track paths to ensure comprehensive and thorough cleaning of the site. However, due to the limitation of direction control, the traditional hard connection floor brush cleaning head is difficult to realize flexible and variable angle adjustment, thereby bringing many inconveniences to cleaning work. For example, when cleaning the corners of walls, the edges of furniture or narrow spaces, due to the inability to freely adjust the angle of the cleaning head, the cleaning effect is often poor, and even manual assistance is needed to complete the cleaning task.

[0013] In some possible embodiments, the first adapter further comprises a third connecting part, which is arranged at an end of the first adapter away from the first connecting part;

[0014] The floor brush head further comprises a fifth connecting part, which is coaxial with the third connecting part, the fifth connecting part is connected with the third connecting part, and the fifth connecting part is connected with the floor brush head through a connecting shaft and can rotate around the connecting shaft.

[0015] In some possible embodiments, the first connecting part is further provided with a positioning assembly for fixing the relative positions of the first adapter and the second adapter;

[0016] The second connecting part is provided with a rotating assembly, which is embedded in the positioning assembly, for rotating the second adapter around the axis of the first adapter.

[0023] Compared with the prior art, the application has the following beneficial effects:

[0024] The cleaning device provided by the application combines the axial rotation freedom of the adapter with the lateral rotation freedom of the floor brush, and the two work together to realize multi-angle and omnidirectional trajectory movement, greatly widening the coverage of the cleaning work. In a conventional design, the combination of the main machine and the floor brush is limited to single-angle rotation in the forward direction of the hand, which limits the flexibility and efficiency of cleaning.

[0045] The specific embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0046] The cleaning device 10 provided by the application comprises an adapter 100, please refer to Figure 1 The adapter 100 comprises a first adapter 110 and a second adapter 120.

[0047] Please refer to Figure 2 The first adapter 110 comprises a first adapter pipe 111 and a first connecting portion 112 located at one end of the first adapter pipe 111, and the first adapter pipe 111 is a hollow columnar structure.

[0048] Please refer to Figure 3 The second adapter 120 comprises a second adapter pipe 121 and a second connecting portion 122 located at one end of the second adapter pipe 121, and the second adapter pipe 121 is a hollow columnar structure.

[0049] Please refer to Figure 4The first connecting part 112 is connected with the second connecting part 122, and the angle formed by the axis A2 of the first adapter pipe 111 and the axis A1 of the second adapter pipe 121 is obtuse; and the second adapter head 120 can rotate in the rotation area 400 with the axis A2 of the first adapter head 110 as the center.

[0050] The cleaning device 10 further comprises a main machine 200 and a floor brush head 300, please refer to Figure 4 The main machine 200 is connected with the second adapter head 120, and the floor brush head 300 is connected with the first adapter head 110.

[0051] In this embodiment, the cleaning device 10 realizes multi-angle and omnidirectional trajectory movement through the cooperation of the axial rotation degree of freedom of the adapter head 100 and the transverse rotation degree of freedom of the floor brush head 300.

[0052] The inventor found that in the traditional cleaning device 10, the combination of the main machine 200 and the floor brush head 300 usually only supports single-angle rotation in the forward direction of hand-holding, which limits the flexibility and efficiency of cleaning. The present scheme realizes axial rotation of the movement direction through the design of the adapter head 100. The adapter head 100 adopts a plumb surface elbow, and the user can control the direction of the floor brush head 300 by twisting the main machine 200. A certain included angle is formed between the first adapter pipe 111 and the second adapter pipe 121, and the second adapter pipe 121 can rotate along the axis of the first adapter pipe 111 in the rotation area 400. At the same time, the main machine 200 is dislocated with the movement axis during movement, so as to form trajectory movement in the direction of the included angle, so that the floor brush head 300 can clean at any angle in the working surface, thereby improving the coverage and efficiency of cleaning.

[0053] In some possible embodiments, the floor brush head 300 comprises a working surface G in contact with the ground.

[0054] The cleaning device 10 has at least two working states. In a first working state, please refer to Figure 4 The angle formed by the first adapter pipe 111 and the second adapter pipe 121 is convex in the direction away from the working surface G of the floor brush head 300; and in a second working state, please refer to Figure 5 The angle formed by the first adapter pipe 111 and the second adapter pipe 121 is convex in the direction towards the working surface G of the floor brush head 300.

[0055] In this embodiment, the adapter head 100 provides double-radian cooperation selection, which means that when the main machine 200 is twisted, the floor brush head 300 can have two different morphological movement directions for the user to choose from, further enriching the flexibility and diversity of cleaning.

[0056] In the first working state, the first adapter pipe 111 shaft and the floor brush head 300 retreat direction is an acute angle. Before rotating the main machine 200, please refer to Figure 6 (a), the floor brush head 300 is parallel to the main machine 200 axis, and can move forward and backward along D3; when rotating the main machine 200, the floor brush head 300 moves left when the main machine 200 rotates right along D2 clockwise; after rotating the main machine 200 and adjusting the main machine 200, please refer to Figure 6 (b), the main machine 200 axis and the floor brush head 300 axis form a certain angle, and when the main machine 200 moves forward and backward, the floor brush head 300 advances and retreats along D4 direction.

[0057] In the second working state, the first adapter pipe 111 shaft and the floor brush head 300 retreat direction is an obtuse angle. Before rotating the main machine 200, please refer to Figure 7 (a), the floor brush head 300 is parallel to the main machine 200 axis, and can move forward and backward along D6; when rotating the main machine 200, the floor brush head 300 moves right when the main machine 200 rotates right along D5 clockwise; after rotating the main machine 200 and adjusting the main machine 200, please refer to Figure 7 (b), the main machine 200 axis and the floor brush head 300 axis form a certain angle, and when the main machine 200 moves forward and backward, the floor brush head 300 advances and retreats along D7 direction.

[0058] In some possible embodiments, please refer to Figure 8 , the first adapter 110 further comprises a third connecting part 113, which is arranged at one end of the first adapter 110 opposite to the first connecting part 112, and the floor brush head 300 is connected with the third connecting part 113.

[0059] Please refer to Figure 9 and Figure 10 , the floor brush head 300 further comprises a fifth connecting part 310, which is coaxial with the third connecting part 113, and the fifth connecting part 310 is connected with the third connecting part 113, and the fifth connecting part 310 is connected with the floor brush head 300 through a connecting shaft 311, and can rotate along D1 direction with the connecting shaft 311 as the center.

[0060] In this embodiment, the connection between the third connecting part 113 and the fifth connecting part 310 can use a detachable connection mode, and the user can select a suitable floor brush head 300 according to different ground materials and cleaning requirements, so as to adapt to different cleaning requirements and scenes.

[0061] In some possible embodiments, please refer to Figure 12 , the first connecting part 112 is further provided with a positioning assembly 130 for fixing the relative positions of the first adapter 110 and the second adapter 120.

[0062] The second connecting part 122 is provided with a rotating assembly 140, which is embedded in the positioning assembly 130, and is used to rotate the second adapter 120 along the axis of the first adapter 110.

[0063] In this embodiment, the positioning assembly 130 and the rotating assembly 140 cooperate to realize the functions of fixed position and relative rotation between the first adapter 110 and the second adapter 120. The first adapter 110 is connected with the brush head 300, and the second adapter 120 can rotate around the axis of the first adapter 110, realizing multi-angle adjustment of the device during use. The user only needs to operate the main machine 200 to drive the brush head 300 to move in all directions through the rotating assembly 140.

[0064] In some possible embodiments, referring to Figure 12 , the positioning assembly 130 includes a first positioning ring 131 and a second positioning ring 132, and a groove for accommodating rotation of the rotating assembly 140 is formed between the first positioning ring 131 and the second positioning ring 132.

[0065] In this embodiment, the positioning assembly 130 includes a first positioning ring 131 and a second positioning ring 132, and a groove is formed on the surface of the first connecting part 112, which can accommodate the rotating assembly 140 connected with the second adapter 120. The size of the rotating assembly 140 should be calculated according to the width of the groove. When the rotating assembly 140 is embedded in the groove, the rotating assembly 140 can realize the rotating action while maintaining stability.

[0066] In some possible embodiments, referring to Figure 11 and Figure 12 , the rotating assembly 140 includes an arc-shaped assembly 141, which is at least partially embedded in the groove, and the arc-shaped assembly 141 is fixed on the second connecting part 122 through a pin 142.

[0067] In this embodiment, the rotating assembly 140 includes an arc-shaped assembly 141. The arc-shaped assembly 141 can be at least partially embedded in the groove in the positioning assembly 130. This embedded design not only provides stable support for the rotating assembly 140, but also limits the shaking range of the rotating assembly 140 during rotation, thereby ensuring the stability of the rotating action. The arc-shaped assembly 141 is fixed on the second connecting part 122 through the pin 142. The pin 142 can not only withstand various forces and moments generated by the rotating assembly 140 during rotation, but also ensure the close cooperation between the arc-shaped assembly 141 and the second connecting part 122, and the user can also disassemble and maintain when needed.

[0068] In some possible implementation manners, referring to Figure 11 The arc-shaped component 141 comprises a plurality of arc-shaped components 141, which are oppositely arranged on the second connecting portion 122.

[0069] For example, two oppositely arranged arc-shaped components 141 are used in the figure. Specifically, the two arc-shaped components 141 are oppositely arranged on both sides of the rotating component 140, and form a close fitting relationship with the groove in the positioning component 130. Such opposite arrangement not only enhances the overall strength of the rotating component 140, but also enables it to maintain stability during rotation. At the same time, due to the close fit between the arc-shaped component 141 and the groove, it effectively prevents the rotating component 140 from shaking or falling off during use. At the same time, it can facilitate the user to disassemble and reduce the cost.

[0070] In some possible implementation manners, referring to Figure 12 The adapter 100 further comprises a sealing ring 150, which is arranged between the first connecting portion 112 and the second connecting portion 122.

[0071] In this embodiment, a sealing ring 150 is installed on the fitting surface between the first connecting portion 112 and the second connecting portion 122. The sealing ring 150 uses a soft rubber sealing material. Such material has good elasticity and wear resistance, which can effectively block the invasion of external impurities such as dust and moisture, thereby protecting the internal structure and components of the adapter 100 from damage, prolonging the service life of the equipment. It can also withstand various forces and torques generated during rotation, ensuring that the adapter 100 always remains stable and reliable during rotation.

[0072] In some possible implementation manners, referring to Figure 11 The second adapter 120 further comprises a fourth connecting portion 123, which is arranged at an end of the second adapter 120 opposite to the second connecting portion 122, and the host 200 is connected with the fourth connecting portion 123.

[0073] In this embodiment, the connection between the adapter 100 and the host 200 can use a detachable connection method, which facilitates the maintenance and cleaning of the equipment 10; or a non-detachable connection method, which can increase the overall stability of the equipment.

[0074] In some possible implementation manners, the first adapter 110 and the second adapter 120 are detachable.

[0075] In this embodiment, the first adapter 110 and the second adapter 120 can be connected through the positioning assembly 130 and the rotating assembly 140. When using this connection method, the first adapter 110 and the second adapter 120 can be disassembled. The detachable connection facilitates the user to maintain, clean and replace the parts of the device.

[0076] Specifically, after the device is used for a long time, it may be necessary to clean the dust or dirt inside the adapter 100, or some parts need to be replaced due to wear and tear. At this time, the user only needs to simply operate the fixing part of the positioning assembly 130 and the rotating assembly 140 to separate the first adapter 110 and the second adapter 120.

[0077] In addition, the detachable connection also provides more choices and flexibility for the user. For example, the user can also replace different specifications or types of floor brush heads 300 to adapt to different floor materials and cleaning requirements.

[0078] The cleaning device 10 provided in the present application combines the axial rotation freedom of the connecting shaft 311 with the lateral rotation freedom of the floor brush, and the two work together to realize multi-angle and omnidirectional trajectory movement, greatly widening the coverage of the cleaning work. In the conventional design, the combination of the main machine 200 and the floor brush is limited to single-handed forward direction angle rotation, which limits the flexibility and efficiency of cleaning. The present application adds a connecting piece to increase the axial rotation ability of the main machine 200 movement direction. When the rotating head rotates, a misalignment angle will naturally be formed between the main machine 200 and the movement axis, so that the trajectory has a included angle direction during movement, so that the floor brush head 300 can clean the ground at any angle.

[0079] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
