Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a cleaning device. Background Art

[0002] In the existing cleaning devices, the cleaning devices usually use a wiping head with a fixed angle to clean the objects to be cleaned. With the continuous improvement of the use environment of the cleaning devices, people are increasingly pursuing a wider use environment for the cleaning devices. Therefore, generally, a wiping head angle adjustment device is provided to adapt to different use environments. However, in the related art, the device for adjusting the wiping head angle is often provided at the handle, and the wiping head angle is adjusted by the cooperation of the moving device and the clamping device at the handle. However, since the backward movement of the moving device and the reset after the movement are all on the same channel, it often falls into the clamping position again when resetting, which is inconvenient for the operator to use.

The driving member will not contact the positioning channel again when resetting, which is convenient for use.

[0047] 2. The force-applying part includes a first elastic member and a second elastic member, and the first elastic member and the second elastic member are coaxially arranged, so that when the driving member moves from the positioning channel to the reset channel at the first end, the first elastic member will be subject to a certain resistance from the second elastic member when applying force to the driving member, so that the force applied by the first elastic member to the driving member is controllable, thereby preventing the driving member from being too tightly fitted to the inner wall of the reset channel and difficult to move; at the same time, when the driving member is at the position of the first end, since the first elastic member and the second elastic member are coaxially arranged, the driving member can be at the center position of the first end of the limit member, which is convenient for secondary movement.

[0048] 3. The driving member includes a third elastic member, which is arranged at one end of the wiping head. When the driving member moves to the first end, the third elastic member is stretched.

[0066] See also Figure 1 , Figure 2 and Figure 3The cleaning device 100 of the embodiment of the utility model includes a wiping head 10, a driving member 20 and a limiting member 30. The driving member 20 is connected to the wiping head 10; the limiting member 30 is arranged in cooperation with the driving member 20, and the limiting member 30 includes a positioning channel 322 and a reset channel 323 arranged along the first end 320 of the limiting member 30 to the second end 321 of the limiting member 30, the first end 320 is the end of the limiting member 30 close to the wiping head 10, the second end 321 is the end of the limiting member 30 away from the wiping head 10, and the positioning channel 322 is connected to the reset channel 323 at the second end 321; when the driving member 20 moves from the first end 320 to the second end 321 along the positioning channel 322 and is positioned to different positions, the angle between the wiping head 10 and the surface to be cleaned is different; after the driving member 20 moves from the first end 320 to the second end 321 along the positioning channel 322, it is driven into the reset channel 323 and resets to the first end 320 of the limiting member 30 along the reset channel 323.

[0067] In the cleaning device 100 of the utility model embodiment, the limit member 30 is provided with a positioning channel 322 and a reset channel 323, and the positioning channel 322 is connected to the reset channel 323. When it is necessary to adjust the angle between the wiping head 10 and the surface to be cleaned, the driving member 20 moves from the first end 320 to the second end 321 along the positioning channel 322 to different positions to achieve the angle adjustment of the wiping head 10. After the driving member 20 moves to the second end 321, the driving member 20 is driven by force from the reset channel 323 back to the position of the first end 320. In this way, the driving member 20 moves along the reset channel 323 when moving to adjust the angle between the wiping head 10 and the surface to be cleaned, and moves along the reset channel 323 when resetting. The driving member 20 will not contact the positioning channel 322 again when resetting, which is convenient for use.

[0068] In addition, by moving the driving member 20 in the positioning channel 322 , different angles between the wiping head 10 and the surface to be cleaned can be achieved, so that the cleaning device 100 cleans the surface to be cleaned from different angles.

[0069] Specifically, the cleaning device 100 is a device for cleaning the surface of an object to be cleaned. The wiping head 10 is a component of the cleaning device 100 that directly contacts the object to be cleaned, and can be made of a soft material with a certain adsorption capacity, such as a sponge, a cloth, and the like.

[0070] The wiping head 10 can be used to remove dirt or impurities on the surface of the object to be cleaned. The material of the wiping head 10 can be selected according to the different objects to be cleaned. For example, for glass surfaces, a soft fiber cloth can be used as the wiping head 10; for metal surfaces, a sponge with fine particles can be used as the wiping head 10. The wiping head 10 can move with the driving member 20. The wiping head 10 and the driving member 20 can be directly connected or indirectly connected.

[0071] The driving member 20 can be a simple member such as a rod, a connecting rod or a slider, or a complex member with a specific shape and structure. The driving member 20 is used to transmit power and adjust the angle of the wiping head 10. When the driving member 20 moves along the positioning channel 322 under the guidance of the limiter 30, the angle of the wiping head 10 changes accordingly to meet different cleaning angle requirements.

[0072] The limiter 30 is used to limit the range of motion of the driver 20. The limiter 30 can be a track fixed on the cleaning device 100 or a structure with a groove. The positioning channel 322 is a channel formed by the limiter 30, extending from the first end 320 to the second end 321 of the limiter 30. The driver 20 moves along the positioning channel 322 to adjust the angle of the wiping head 10. The positioning channel 322 can be designed as a straight line, a curve or other specific shapes to meet different cleaning angle requirements.

[0073] The reset channel 323 is a channel formed by the stopper 30. The reset channel 323 is connected to the second end 321 of the positioning channel 322. The driving member 20 moves along the reset channel 323 and resets to the first end 320 to achieve the reset of the angle of the wiping head 10. The movement of the driving member 20 can be manual or automatic through a mechanical, pneumatic or hydraulic system.

[0074] See also Figure 3 In some embodiments, the cleaning device 100 further includes a force applying portion 101, which is used to drive the driving member 20 to move toward the reset channel 323 after the driving member 20 moves from the first end 320 to the second end 321 along the positioning channel 322, so that the driving member 20 is driven into the reset channel 323.

[0075] In this way, the force applying part 101 can drive the driving member 20 into the reset channel 323 after completing the positioning action, thereby realizing the reset operation of the driving member 20, so that the driving member 20 can return to the initial position after each cleaning operation.

[0076] Specifically, the force applying part 101 is used to provide the necessary force to drive the driving member 20 to enter the reset channel 323 after the driving member 20 moves along the positioning channel 322 to the second end 321, thereby reducing additional operations and improving efficiency. The force applying part 101 can be in various forms, such as a spring, a memory alloy, etc. The driving member 20 enters the reset channel 323 under the action of the force applying part 101, which is the beginning of the reset process.

[0077] See also Figure 3 , Figure 4 and Figure 5 In some embodiments, the cleaning device 100 further includes a first supporting portion 102 that is provided in cooperation with the limiting member 30;

[0078] The force applying part 101 includes a first elastic member 21 , and the first elastic member 21 is disposed between the driving member 20 and the first supporting part 102 ;

[0079] When the driving member 20 is located in the positioning channel 322, the first elastic member 21 is compressed by the squeezing force of the first supporting portion 102 and the driving member 20 to store force;

[0080] When the driving member 20 moves to the second end 321 , the first elastic member 21 releases force to push the driving member 20 to move toward the reset channel 323 .

[0081] Thus, by setting the first elastic member 21, when the driving member 20 moves to the second end 321 of the positioning channel 322, the unloading force of the first elastic member 21 can automatically push the driving member 20 to move toward the reset channel 323, thereby achieving automatic reset. Due to the fast response characteristics of the first elastic member 21, the driving member 20 can complete the process from positioning to reset in a very short time, thereby improving the response speed of the entire cleaning device 100. In addition, the first elastic member 21 can mitigate the vibration generated during the movement of the driving member 20, thereby making the movement process of the driving member 20 smooth.

[0082] Specifically, the first support portion 102 is used to provide a support point at one end of the first elastic member 21, and the first support portion 102 is a reference point for the compression and release of the first elastic member 21. The first elastic member 21 can be a spring, an elastic pad or other elastic component, which is used to store force when compressed and generate a driving force when released. When the driving member 20 reaches the second end 321, the first elastic member 21 releases its compressed accumulated energy to generate a driving force.

[0083] See also Figure 3 and Figure 5 In some embodiments, the force applying portion 101 is used to push the driving member 20 to move toward the reset channel 323 and to the reset position after the driving member 20 moves from the first end 320 to the second end 321 along the positioning channel 322, so that the driving member 20 is driven to enter the reset channel 323 from the reset position.

[0084] In this way, after the driving member 20 completes the positioning action and reaches the second end 321 of the positioning channel 322, the force applying part 101 can not only push the driving member 20 to move toward the reset channel 323, but also drive the driving member 20 to accurately move to the reset position, and further enter the reset channel 323 from the reset position. This allows the wiping head 10 to be reset to the initial state after each cleaning, which improves convenience.

[0085] Specifically, the reset position may be a position close to the connection between the positioning channel 322 and the reset channel 323 at the second end 321 . From this position, the driving member 20 may smoothly enter the reset channel 323 and complete the reset process.

[0086] See also Figure 3 and Figure 6 In some embodiments, the limiting member 30 is further provided with a first guide portion 324;

[0087] The first guide portion 324 is used to guide the driving member 20 to enter the reset channel 323 from the reset position when the driving member 20 at the reset position is driven to move.

[0088] Thus, when the driving member 20 is at the reset position, the first guide portion 324 can effectively guide the driving member 20 to smoothly and accurately enter the reset channel 323. This improves the smoothness of the reset action of the driving member 20, and also improves the stability of the operation of the entire cleaning device 100, avoiding the jamming or misalignment phenomenon that may be caused by the poor reset path.

[0089] Specifically, the first guide portion 324 may be a groove or a protrusion of a specific shape on the limiting member 30 , and the first guide portion 324 may match a specific portion on the driving member 20 .

[0090] See also Figure 3 and Figure 6 In some embodiments, a side of the limiting member 30 close to the driving member 20 is recessed to form a positioning channel 322 and a reset channel 323;

[0091] A first inclined area is provided at the end of the side wall of the reset channel 323 close to the positioning channel 322 close to the second end 321, and the first inclined area is inclined along the direction from the second end 321 to the first end 320 away from the positioning channel 322; the first inclined area forms a first guide portion 324.

[0092] In this way, the first inclined area is inclined in a specific direction, providing a clear guide path for the driving member 20, so that the driving member 20 can slide naturally along the first inclined area when resetting, achieving a smooth transition from the positioning channel 322 to the reset channel 323, and avoiding possible jamming or misalignment during the reset process.

[0093] In addition, the design of forming the positioning channel 322 and the reset channel 323 by recessing one side of the limit member 30 effectively utilizes the space inside the cleaning device 100, making the overall structure more compact, reducing the volume and weight of the cleaning device 100, and facilitating carrying and use.

[0094] Specifically, the region of the reset channel 323 near the positioning channel 322 includes a side wall, and the end of the side wall near the second end 321 is provided with a first inclined region. The depression refers to a groove, a notch or other forms of depression structures formed on the stopper 30 .

[0095] See also Figure 3In some embodiments, the driving member 20 is provided with a clamping member 24, and when the driving member 20 moves from the first end 320 to the second end 321, the clamping member 24 slides along the positioning channel 322;

[0096] When the force applying part 101 drives the driving member 20 to move toward the reset channel 323, the clamping member 24 moves to the reset position, and the reset position is located on the side of the first inclined area away from the first end 320;

[0097] When the driving member 20 is driven to move toward the first end 320 , the engaging member 24 slides along the first inclined area to the return channel 323 , so as to return to the first end 320 along the return channel 323 .

[0098] Thus, by providing the clamping member 24 on the driving member 20 and sliding the clamping member 24 along the positioning channel 322, precise control of the angle of the wiping head 10 is achieved. The interaction between the clamping member 24 and the positioning channel 322 enables the wiping head 10 to be stably locked at different positions, thereby improving the stability and cleaning effect during the cleaning process.

[0099] Specifically, the clamping member 24 may be a protrusion, a groove or other structure on the driving member 20 . The clamping member 24 may contact the first inclined area and slide to the reset channel 323 along the inclined direction of the first inclined area.

[0100] See also Figure 3 and Figure 6 In some embodiments, a plurality of engaging positions 103 for positioning the driving member 20 are provided on the side wall of the positioning channel 322 close to the reset channel 323;

[0101] When the engaging member 24 moves along the positioning channel 322 from the first end 320 to the second end 321 and is positioned at different engaging positions 103 , the angles between the wiping head 10 and the surface to be cleaned are different.

[0102] In this way, by setting a plurality of latching positions 103 on the side wall of the positioning channel 322 close to the reset channel 323, the driving member 20 can be stably locked at a plurality of predetermined positions, and each latching position 103 corresponds to a different angle between the wiping head 10 and the surface to be cleaned, thereby achieving different angle adjustments between the wiping head 10 and the surface to be cleaned, which enables the cleaning device 100 to meet the requirements of cleaning angles for different cleaning scenarios and surface shapes.

[0103] Specifically, the engaging positions 103 may be a plurality of fixed positions for positioning the driving member 20 provided on the side wall of the positioning channel 322. These engaging positions 103 may be protrusions, grooves or other mechanical structures. For example, the engaging positions 103 may be grooves spaced apart from the first end 320 toward the second direction.

[0104] When the clamping member 24 is positioned at different clamping positions 103, the angle between the wiping head 10 and the surface to be cleaned will change accordingly. This means that by changing the position of the clamping member 24, the inclination of the wiping head 10 can be adjusted to meet different cleaning requirements.

[0105] See also Figure 5 , Figure 7 and Figure 8 In some embodiments, the cleaning device 100 further includes a rod body 40, the driving member 20 and the limiting member 30 are both disposed in the rod body 40, and the positioning channel 322 and the reset channel 323 are both extended along the axial direction of the rod body 40;

[0106] The first supporting portion 102 is a portion of the inner wall of the rod body 40 close to the positioning channel 322 .

[0107] In this way, by arranging the driving member 20 and the limiting member 30 in the rod body 40, the adverse effects of external factors on the driving member 20 and the limiting member 30 are reduced, and the service life of the driving member 20 and the limiting member 30 is extended. In addition, the first support portion 102 serves as the inner wall of the rod body 40, which makes it difficult for the first elastic member 21 to shake when it is pressed against the first support portion 102, thereby making the reset process more stable.

[0108] Specifically, the rod body 40 may be a long strip structure made of metal or plastic. The rod body 40 may form a hollow area, and the driving member 20 and the stopper 30 may be arranged in the hollow area. The axial direction of the rod body 40 refers to the direction in which the central axis of the rod body 40 extends.

[0109] See also Figure 3 and Figure 6 , in some embodiments, the positioning channel 322 is connected to the resetting channel 323 at the first end 320;

[0110] The driving member 20 returning to the first end 320 is driven to enter the positioning channel 322 from the reset channel 323 .

[0111] Thus, by connecting the positioning channel 322 with the reset channel 323 at the first end 320 , the driving member 20 can return to the positioning channel 322 after completing the reset action, which forms a complete circulation operation path, so that the cleaning device 100 can perform the cleaning operation again after reset.

[0112] See also Figure 3 and Figure 6 In some embodiments, the force applying portion 101 included in the cleaning device 100 is also used to drive the driving member 20 to move toward the positioning channel 322 after the driving member 20 moves from the second end 321 to the first end 320 along the reset channel 323, so that the driving member 20 is driven into the positioning channel 322.

[0113] In this way, the force applying part 101 is not only used to push the driving member 20 into the reset channel 323, but also can drive the driving member 20 to return from the reset channel 323 to the positioning channel 322, thereby realizing a two-way force applying function, which makes the operation of the cleaning device 100 more convenient.

[0114] See also Figure 5 In some embodiments, the cleaning device 100 further includes a second supporting portion 104 that cooperates with the limiting member 30;

[0115] The force applying part 101 includes a second elastic member 22 , and the second elastic member 22 is disposed between the driving member 20 and the second supporting part 104 ;

[0116] When the driving member 20 is located in the reset channel 323, the second elastic member 22 is compressed by the squeezing force of the second supporting portion 104 and the driving member 20 to store force;

[0117] When the driving member 20 moves to the first end 320 , the second elastic member 22 releases force to push the driving member 20 to move toward the positioning channel 322 .

[0118] Thus, by setting the second elastic member 22, when the driving member 20 moves to the first end 320, the unloading force of the second elastic member 22 can automatically push the driving member 20 to move toward the positioning channel 322. Due to the fast response characteristics of the first elastic member 21, the driving member 20 can move toward the positioning channel 322 in a very short time, thereby improving the response speed of the entire cleaning device 100. In addition, the second elastic member 22 can mitigate the vibration generated during the movement of the driving member 20, thereby making the movement process of the driving member 20 smooth.

[0119] Specifically, the second support portion 104 is used to provide a support point at one end for the second elastic member 22, and the second support portion 104 is a reference point for the compression and release of the second elastic member 22. The second elastic member 22 can be a spring, an elastic pad or other elastic component, which is used to store force when compressed and generate a driving force when released. When the driving member 20 reaches the first end 320, the second elastic member 22 releases its compressed accumulated energy to generate a driving force.

[0120] See also Figures 2 to 5In one embodiment, the first elastic member 21 and the second elastic member 22 are coaxially arranged, so that when the driving member 20 moves from the positioning channel 322 to the reset channel 323 at the first end 320, the first elastic member 21 will be subject to a certain resistance from the second elastic member 22 when applying force to the driving member 20, so that the force applied by the first elastic member 21 on the driving member 20 is controllable, thereby preventing the driving member 20 from being too tightly fitted to the inner wall of the reset channel 323 and being difficult to move; at the same time, when the driving member 20 is at the position of the first end 320, since the first elastic member 21 and the second elastic member 22 are coaxially arranged, the driving member 20 is able to be at the center position of the first end 320 of the limiting member 30, which is convenient for secondary movement.

[0121] See also Figure 3 In some embodiments, the force-applying portion 101 is used to push the driving member 20 to move toward the positioning channel 322 and to the initial position after the driving member 20 returns from the second end 321 to the first end 320 along the reset channel 323, so that the driving member 20 is driven to enter the positioning channel 322 from the initial position.

[0122] In this way, the force-applying portion 101 can drive the driving member 20 into the positioning channel 322 and move to the initial position after completing the resetting action, so as to prepare for the next cleaning task.

[0123] Specifically, the initial position may be a position close to the connection between the positioning channel 322 and the reset channel 323 at the first end 320 . From this position, the driving member 20 may smoothly enter the positioning channel 322 and complete the process of adjusting the angle of the wiping head 10 .

[0124] See also Figure 3 In some embodiments, the limiting member 30 is further provided with a second guide portion 325;

[0125] The second guide portion 325 is used to guide the driving member 20 to enter the positioning channel 322 from the initial position when the driving member 20 located at the initial position is driven to move.

[0126] Thus, when the driving member 20 is at the initial position, the second guide portion 325 can effectively guide the driving member 20 to smoothly and accurately enter the positioning channel 322. This improves the smoothness of the movement of the driving member 20, and also improves the stability of the operation of the entire cleaning device 100, avoiding the jamming or misalignment phenomenon that may be caused by the unsmooth movement path.

[0127] Specifically, the second guide portion 325 may be a groove or a protrusion of a specific shape on the limiting member 30 , and the second guide portion 325 may match a specific portion on the driving member 20 .

[0128] See also Figure 3In some embodiments, a second inclined region is provided at the end of the side wall of the positioning channel 322 close to the reset channel 323 close to the first end 320, and the second inclined region is inclined in the direction from the first end 320 to the second end 321 in a direction away from the reset channel 323; the second inclined region forms a second guide portion 325.

[0129] In this way, the second inclined area is inclined along a specific direction, providing a clear guide path for the driving member 20, so that the driving member 20 can slide naturally along the second inclined area when resetting, achieving a smooth transition from the reset channel 323 to the positioning channel 322, and avoiding possible jamming or misalignment during the movement of the driving member 20.

[0130] Specifically, the region of the reset channel 323 close to the reset channel 323 includes a side wall, and an end of the side wall close to the first end 320 is provided with a second inclined region.

[0131] See also Figure 3 In some embodiments, the driving member 20 is provided with a clamping member 24, and when the driving member 20 moves from the second end 321 to the first end 320, the clamping member 24 slides along the reset channel 323;

[0132] When the force applying part 101 drives the driving member 20 to move toward the positioning channel 322 , the clamping member 24 moves to the initial position, which is located at a side of the second inclined area away from the second end 321 ;

[0133] When the driving member 20 is driven to move toward the second end 321 , the engaging member 24 slides along the second inclined area to the positioning channel 322 .

[0134] Thus, by arranging the clamping member 24 on the driving member 20 and sliding the clamping member 24 along the resetting channel 323, the angle of the wiping head 10 is reset. Moreover, after the clamping member 24 moves to the initial position, it can slide to the positioning channel 322 to complete the conversion from resetting to positioning.

[0135] See also Figure 4 and Figure 5 In some embodiments, the second supporting portion 104 is a portion of the inner wall of the rod body 40 on which the driving member 20 and the limiting member 30 are disposed, close to the reset channel 323 .

[0136] In this way, the second support portion 104 serves as the inner wall of the rod body 40 , which makes it difficult for the second elastic member 22 to shake when being pressed against the second support portion 104 , thereby making the positioning process more stable.

[0137] See also Figure 1 and Figure 2 In some embodiments, the driving member 20 includes a third elastic member 23, and the third elastic member 23 is disposed between the driving member 20 and the wiping head 10;

[0138] When the driving member 20 moves along the positioning channel 322 from the first end 320 to the second end 321 , the third elastic member 23 stretches to store force;

[0139] After the driving member 20 is driven into the reset channel 323 , the third elastic member 23 releases the force to pull the driving member 20 back to the first end 320 along the reset channel 323 .

[0140] In this way, the driving member 20 moves from the positioning channel 322 to the reset channel 323 under the action of the first elastic member 21. Due to the restoring force of the third elastic member 23, the driving member 20 automatically returns to the first end 320. In this way, the operator's operation of moving the driving member 20 to the first end 320 again can be reduced, thereby greatly improving the user experience.

[0141] Specifically, the third elastic member 23 may be an elastic rope, and the third elastic member 23 may connect the driving member 20 and the wiping head 10 , so that the angle of the wiping head 10 changes with the movement of the driving member 20 .

[0142] See also Figure 7 and Figure 8 In one embodiment, a through slot 41 may be formed on the rod body 40, and the through slot 41 extends from the first end 320 to the second end 321. The driving member 20 includes a connecting portion 25, and the connecting portion 25 is used to move along the through slot 41. The connecting portion 25 is driven to move along the extending direction of the through slot 41. During the movement of the connecting portion 25, the driving member 20 as a whole moves along the extending direction of the through slot 41.

[0143] See also Figures 1 to 8 In a specific embodiment, the cleaning device 100 is in an initial state, the driving member 20 is located at the first end 320 of the positioning channel 322, and the angle of the wiping head 10 at this time is the initial angle. The operator or the automatic control system drives the driving member 20 to move along the positioning channel 322 from the first end 320 to the second end 321. During this process, the first elastic member 21 and / or the third elastic member 23 stretch and store force. As the driving member 20 moves, the angle of the wiping head 10 relative to the surface to be cleaned changes. The clamping member 24 slides along the positioning channel 322 and is positioned to different clamping positions 103 so that the wiping head 10 is fixed at different angles.

[0144] After the cleaning operation is completed, the force applying part 101 starts to work, driving the driving member 20 to move toward the reset channel 323. At this time, the second elastic member 22 is compressed to assist the movement of the driving member 20. After the driving member 20 enters the reset channel 323, the first elastic member 21 and / or the third elastic member 23 release the force, automatically pulling the driving member 20 back to the first end 320 along the reset channel 323. The second supporting part 104 and the first inclined area provide a guiding function in this process.

[0145] The driving member 20 is pulled by the third elastic member 23 to return to the first end 320 of the positioning channel 322, ready for the next cleaning operation or to stop the cleaning operation. The force applying part 101 can act on the driving member 20 again to push the driving member 20 from the reset channel 323 into the positioning channel 322. The above process can be repeated to achieve continuous cleaning operations. The limiting member 30 limits the range of motion of the driving member 20 during the entire process to ensure the safety and accuracy of the operation.
