Description

Technical Field

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

[0002] With the development of science and technology and social progress, more and more families have begun to use floor cleaning machines instead of traditional mops for cleaning. In order to collect water stains on the floor, a scraper strip is generally provided on the roller brush of the floor scrubber to keep close to the ground, so as to reduce the residual water stains on the ground. The floor scrubber in the prior art has a soft rubber scraper strip on the rear side of the roller brush. When the roller brush moves forward, the scraper strip is turned back under the friction of the ground and scrapes water close to the ground to reduce the residual water stains on the ground. When users mop the floor for small area stains, they tend to push and pull back and forth to clean. For large spaces such as the entire room and living room, the overall trend is to clean backwards, but after pulling back, the roller brush with water wets the ground again, and the residual water stains on the ground are not reduced, resulting in poor cleaning effect. Utility Model Content

[0003] Based on this, it is necessary to provide a wiper device and a cleaning device to address the problem that the roller brush with water wets the ground again after the floor scrubber is pulled back in the prior art, the residual water stains on the ground cannot be reduced, and the cleaning effect is poor.

[0004] The technical solution is as follows:

[0005] In one aspect, a wiper device is provided, which is applied to a cleaning device having a cleaning body, and the wiper device comprises:

[0007] A friction member, which is movably mounted on the cleaning body and is used for frictionally cooperating with the surface to be cleaned;

[0008] A transmission assembly, which is in transmission connection with the wiper element and the friction element;

[0009] When the cleaning body moves forward, the friction member drives the wiper member to move upward through the transmission assembly under the action of friction force; when the cleaning body moves backward, the transmission assembly is released by the friction member, and the wiper member moves downward to reset.

[0010] In the wiper device of the above embodiment, when the cleaning body moves forward, the friction member contacts and rubs the surface to be cleaned. Under the action of friction force, the friction member moves backward relative to the cleaning body, and drives the wiper member to move upward to the avoidance position through the transmission component, and the wiper member is away from the surface to be cleaned, so that no wiping is achieved during the forward push process. When the cleaning body moves backward, the friction member contacts and rubs the surface to be cleaned. Under the action of friction force, the friction member moves forward relative to the cleaning body to release the transmission component, and the wiper member moves downward to the wiping position under the action of gravity and contacts the surface to be cleaned, so that wiping is achieved during the backward pull process.

[0011] The wiper device in the present application utilizes the friction between the friction member and the surface to be cleaned during the movement of the cleaning body as the driving force, and selectively transmits the driving force to the wiper member through the transmission component, so that the wiper member does not wipe water during the forward push, and effectively wipes the water stains generated by the cleaning body during the backward pull, thereby satisfying the user's overall habit of cleaning backwards and ensuring the cleaning effect of the cleaning device. In addition, the friction between the friction member and the surface to be cleaned during the movement of the cleaning body is used as the driving force, which has a simple structure and does not require power drive. While easily achieving the above technical effects, it also reduces the cost of the wiper device.

[0041] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, a wiper device 10 is provided, which is applied to a cleaning device 30 having a cleaning body 20. The wiper device 10 includes a wiper member 100, a friction member 200 and a transmission assembly 300. The wiper member 100 is movably mounted on the cleaning body 20. The friction member 200 is movably mounted on the cleaning body 20 and is used for frictionally cooperating with the surface to be cleaned. The transmission assembly 300 is transmission-connected to both the wiper member 100 and the friction member 200. When the cleaning body 20 moves forward, the friction member 200 drives the wiper member 100 to move upward through the transmission assembly 300 under the action of friction force; when the cleaning body 20 moves backward, the transmission assembly 300 is released by the friction member 200, and the wiper member 100 moves downward to reset.

[0043] like Figure 2 and Figure 3As shown, specifically in this embodiment, the friction member 200 can move backward relative to the cleaning body 20 when the cleaning body 20 moves forward to drive the transmission assembly 300; and the friction member 200 can also move forward relative to the cleaning body 20 when the cleaning body 20 moves backward to release the transmission assembly 300.

[0044] When the cleaning body 20 moves forward, the friction member 200 contacts and rubs against the surface to be cleaned. Under the action of the friction force, the friction member 200 moves backward relative to the cleaning body 20, and drives the wiper member 100 to move upward to the avoidance position through the transmission assembly 300. The wiper member 100 is away from the surface to be cleaned, so that no wiping is achieved during the forward push process.

[0045] When the cleaning body 20 moves backward, the friction member 200 contacts and rubs the surface to be cleaned. Under the action of friction force, the friction member 200 moves forward relative to the cleaning body 20 to release the transmission assembly 300. The wiper member 100 moves downward to the wiping position under the action of gravity and contacts the surface to be cleaned, thereby achieving wiping during the backward pull process.

[0046] The wiper device 10 in the above embodiment uses the friction between the friction member 200 and the surface to be cleaned during the movement of the cleaning body 20 as a driving force, and selectively transmits the driving force to the wiper member 100 through the transmission assembly 300, so that the wiper member 100 does not wipe water during the forward push, and the wiper member 100 effectively wipes the water stains generated by the cleaning body 20 during the backward pull, thereby satisfying the user's overall habit of cleaning backwards and ensuring the cleaning effect of the cleaning device 30. In addition, the friction between the friction member 200 and the surface to be cleaned during the movement of the cleaning body 20 is used as a driving force, which has a simple structure and does not require a power source to drive. While the above technical effects are easily achieved, the cost of the wiper device 10 is also reduced.

[0047] The wiper 100 may be configured as a wiper blade, a wiper strip or other wiper structures. The wiper 100 may be directly and movably mounted on the cleaning body 20, or may be movably mounted on the cleaning body 20 via an intermediate element (e.g., a mounting seat). The wiper 100 may be rotatably mounted on the cleaning body 20, or may be slidably mounted on the cleaning body 20.

[0048] like Figure 3 , Figure 4 and Figure 5 As shown, the wiper device 10 further includes a mounting bracket 400, which is mounted on the front end of the cleaning body 20, and the wiper element 100 is movably mounted on the mounting bracket 400. In this way, the wiper element 100 can be pre-mounted on the mounting bracket 400 and then mounted on the cleaning body 20 through the mounting bracket 400, thereby improving the convenience of the wiper device 10.

[0049] The mounting bracket 400 can be mounted on the front end of the cleaning body 20 by snapping, plugging, screwing or other connection methods.

[0050] like Figure 5 , Figure 6 and Figure 7 As shown, optionally, the mounting bracket 400 is provided with at least one mounting portion 410, and each mounting portion 410 is used to be detachably connected to the cleaning body 20. In this way, the cleaning body 20 can flexibly replace the wiper device 10 according to actual use needs, thereby improving the practicality of the cleaning device 30.

[0051] The number of the mounting portions 410 can be flexibly adjusted according to the actual use requirements. In this embodiment, the number of the mounting portions 410 is three, and the three mounting portions 410 are arranged along the length direction of the mounting bracket 400 (such as Figure 5 The mounting portion 410 can be set as a card slot, and the cleaning body 20 is provided with buckles 202, the number of buckles 202 is the same as the number of card slots, and each buckle 202 is correspondingly engaged with each card slot.

[0052] like Figure 1 and Figure 5 As shown, in one embodiment, the movable direction of the wiper member 100 relative to the mounting bracket 400 is set to a first direction (eg Figure 1 In the direction shown by C in the figure), the mounting bracket 400 is provided with at least one first sliding portion 420 extending along the first direction, and the wiper member 100 is provided with at least one second sliding portion 110, and each second sliding portion 110 is correspondingly slidably matched with each first sliding portion 420. In this way, the mounting bracket 400 can guide the wiper member 100 through the first sliding portion 420 and the second sliding portion 110, so as to ensure that the wiper member 100 reciprocates along the first direction relative to the mounting bracket 400, thereby improving the reliability of the wiper device 10.

[0053] Among them, the first direction can be a vertical direction or an inclined direction set at an angle to the vertical direction. It only needs to ensure that when the cleaning body 20 moves forward, the wiper element 100 is away from the surface to be cleaned, and when the cleaning body 20 moves backward, the wiper element 100 contacts the surface to be cleaned for wiping.

[0054] Among them, the number of the first sliding part 420 and the second sliding part 110 can be flexibly adjusted according to the actual use needs. Specifically in this embodiment, the first sliding part 420 is set as a first guide slot, and the first guide slot extends to the bottom wall of the mounting bracket 400. The second sliding part 110 is set as a first guide rib, and the number of the first guide slots is three. The three first guide slots all extend along the first direction and are arranged at intervals along the length direction of the mounting bracket 400. The number of the first guide ribs is the same as the number of the first guide slots, and the three first guide ribs are correspondingly slidably matched with the three first guide slots.

[0055] like Figure 5 and Figure 8 As shown, optionally, the wiper member 100 is further provided with at least one third sliding portion 120, and the cleaning body 20 is further provided with at least one fourth sliding portion 201 extending along the first direction, and each third sliding portion 120 is correspondingly slidably matched with each fourth sliding portion 201. In this way, the cleaning body 20 can guide the wiper member 100 through the third sliding portion 120 and the fourth sliding portion 201, so as to ensure that the wiper member 100 reciprocates along the first direction relative to the mounting bracket 400, thereby improving the reliability of the wiper device 10.

[0056] Among them, the number of the third sliding part 120 and the fourth sliding part 201 can be flexibly adjusted according to the needs of actual use. Specifically in this embodiment, the cleaning body 20 includes a top shell 22. The fourth sliding part 201 is set as a second guide slot, and the second guide slot extends to the bottom wall of the top shell 22. The third sliding part 120220 is set as a second guide rib, and the number of the second guide slots is three. The three second guide slots all extend along the first direction and are spaced apart along the length direction of the mounting bracket 400. The number of the second guide ribs is the same as the number of the second guide slots, and the three second guide ribs correspond to the three second guide slots in sliding cooperation.

[0057] like Figure 5 As shown, optionally, the bottom of the wiper 100 is configured to be in a pointed shape. In this way, the bottom of the wiper 100 is easily elastically deformed to keep in contact with the surface to be cleaned, ensuring that the wiper 100 effectively wipes water and improving the reliability of the wiper device 10.

[0058] like Figure 5 , Figure 6 and Figure 7 As shown, in one embodiment, the wiper device 10 further includes an elastic member 500, which is installed between the mounting bracket 400 and the wiper member 100 and is configured to be compressed when the cleaning body 20 moves forward and rebound when the cleaning body 20 moves backward.

[0059] like Figure 2 and Figure 6As shown, when the cleaning body 20 moves forward, the friction member 200 contacts and rubs against the surface to be cleaned. Under the action of the friction force, the friction member 200 moves backward relative to the cleaning body 20, and drives the wiper member 100 to move upward to the avoidance position through the transmission assembly 300. The elastic member 500 is compressed, and the wiper member 100 moves away from the surface to be cleaned, so that no wiping is achieved during the forward push process.

[0060] like Figure 3 As shown, when the cleaning body 20 moves backward, the friction member 200 contacts and rubs the surface to be cleaned. Under the action of the friction force, the friction member 200 moves forward relative to the cleaning body 20 to release the transmission assembly 300, and the elastic member 500 rebounds and resets. The wiper member 100 moves downward to the wiping position under the action of the elastic member 500 and contacts the surface to be cleaned, thereby achieving wiping during the backward pull process.

[0061] The elastic member 500 may be configured as a spring, an elastic sleeve, an elastic pad or other elastic structures.

[0062] like Figure 5 , Figure 6 and Figure 7 As shown, optionally, the movable direction of the wiper member 100 relative to the mounting bracket 400 is set to a first direction, the mounting bracket 400 is provided with at least one limiting portion 430, each limiting portion 430 extends along the first direction and is arranged at intervals along a direction perpendicular to the first direction, the elastic member 500 is set as a spring, the number of the springs is the same as the number of the limiting portions 430, each spring is correspondingly sleeved on each limiting portion 430, and each is in conflict with the wiper member 100. In this way, the limiting portion 430 can limit and guide the spring, ensure that the spring is extended and retracted along the first direction to apply a rebound force along the first direction to the wiper member 100, thereby ensuring that the wiper member 100 contacts the surface to be cleaned for wiping, and improving the reliability of the wiper device 10.

[0063] The number of springs and limiting parts 430 can be flexibly adjusted according to the actual use needs. Specifically in this embodiment, the limiting part 430 can be set as a limiting rib, and the number of limiting ribs is two, and the two limiting ribs are arranged at intervals along the length direction of the mounting bracket 400. The top of the wiper 100 is provided with limiting holes 130, and the number of limiting holes 130 is the same as the number of limiting ribs, and each limiting rib is correspondingly plugged and matched with each limiting hole 130. The spring is in contact with the top wall of the wiper 100.

[0064] like Figure 2 and Figure 5 As shown, in one embodiment, the transmission assembly 300 includes a transmission rope 310 , one end of the transmission rope 310 is connected to the wiper member 100 , and the other end of the transmission rope 310 is connected to the friction member 200 .

[0065] One end of the transmission rope 310 can be connected to the friction member 200 by snapping, plugging or other fixed assembly methods, and the other end of the transmission rope 310 can be connected to the wiper member 100 by snapping, plugging or other fixed assembly methods. Specifically in this embodiment, the transmission rope 310 can be set as a steel wire.

[0066] like Figure 2 , Figure 3 and Figure 5 As shown, further, the transmission assembly 300 includes a guide sleeve 320, the guide sleeve 320 is installed on the cleaning body 20, and the transmission rope 310 is movably arranged in the guide sleeve 320. In this way, the guide sleeve 320 can guide and protect the transmission rope 310, ensuring that the friction member 200 can drive the wiper member 100 to move upward through the transmission rope 310, thereby improving the reliability of the wiper device 10.

[0067] Specifically in this embodiment, the guide sleeve 320 can be installed on the cleaning body 20 by snapping, plugging or other methods.

[0068] like Figure 2 , Figure 3 and Figure 5 As shown, optionally, the movable direction of the friction member 200 relative to the cleaning body 20 is set to the second direction, and the end of the guide sleeve 320 close to the friction member 200 extends along the second direction, so that the transmission rope 310 between the guide sleeve 320 and the friction member 200 is tensioned along the second direction. In this way, the force transmission direction between the transmission rope 310 and the friction member 200 is the same as the second direction, ensuring that the friction member 200 can move smoothly on the cleaning body 20, thereby improving the reliability of the wiper device 10.

[0069] Specifically in this embodiment, the second direction can be the same as the movement direction of the cleaning body 20, or it can be set at an angle to the movement direction of the cleaning body 20. It only needs to ensure that when the cleaning body 20 moves forward, the friction member 200 drives the wiper member 100 to move upward through the transmission rope 310 to move away from the surface to be cleaned. When the cleaning body 20 moves backward, the force between the friction member 200 and the transmission rope 310 disappears, and the wiper member 100 can move downward to contact the surface to be cleaned.

[0070] like Figure 2 , Figure 3 and Figure 5As shown, in one embodiment, the moving direction of the wiper member 100 relative to the mounting bracket 400 is set to a first direction, the transmission assembly 300 further includes a rolling member 330, the rolling member 330 is rotatably mounted on the mounting bracket 400, and is located above the wiper member 100 along the first direction, and the transmission rope 310 between the friction member 200 and the wiper member 100 is tensioned and wound around the rolling member 330, so that the transmission rope 310 between the rolling member 330 and the wiper member 100 is tensioned and arranged along the first direction. In this way, the rolling member 330 can change the extension direction of the transmission rope 310 between the friction member 200 and the wiper member 100, so that the transmission rope 310 applies a driving force along the first direction to the wiper member 100, ensuring that the transmission rope 310 can pull the wiper member 100 to move upward, thereby improving the reliability of the wiper device 10.

[0071] Specifically in this embodiment, the direction of the line between the end of the guide sleeve 320 away from the friction member 200 and the position where the wiper member 100 is connected to the transmission rope 310 is set as the third direction. The rolling member 330 is rotatably mounted on the mounting bracket 400 and is located between the guide sleeve 320 and the wiper member 100 along the first direction. The transmission rope 310 between the guide sleeve 320 and the wiper member 100 is tensioned and wound around the rolling member 330, so that the transmission rope 310 between the rolling member 330 and the wiper member 100 is changed from being tensioned along the first direction along the original third direction.

[0072] Specifically in this embodiment, the rolling member 330 can be configured as a roller, and the roller can be rotatably mounted on the mounting bracket 400 via a rotating shaft.

[0073] like Figure 2 , Figure 3 and Fig. 9 As shown, in one embodiment, the friction member 200 is provided with a guide portion 210, and the guide portion 210 and the cleaning body 20 are arranged along the movement direction of the cleaning body 20 (such as Figure 1 In this way, the guide portion 210 can play a guiding role, ensuring that the friction member 200 can move smoothly on the cleaning body 20, thereby improving the reliability of the wiper device 10.

[0074] The installation position of the friction member 200 on the cleaning body 20 can be flexibly adjusted according to actual use requirements. For example, the friction member 200 can be installed on the bottom or side wall of the cleaning body 20 .

[0075] Optionally, the cleaning body 20 includes a lower shell 24 , and the friction member 200 is movably mounted on the bottom of the lower shell 24 .

[0076] like Fig. 9As shown, specifically in this embodiment, the bottom of the lower shell 24 is provided with a mounting groove 203, and both side walls of the mounting groove 203 are provided with guide ribs 204 extending along the second direction. The guide portion 210 can be set as a guide groove. The top of the friction member 200 is correspondingly installed in the mounting groove 203. Both opposite side walls of the friction member 200 are provided with guide grooves; the two guide ribs 204 are correspondingly slidably matched with the two guide grooves. Along the second direction, the width of the guide groove is greater than the width of the friction member 200. When the friction member 200 slides to a position that interferes with the rear side wall of the mounting groove 203, the wiper member 100 moves upward to the avoidance position. When the friction member 200 slides to a position that interferes with the front side wall of the mounting groove 203, the wiper member 100 moves downward to the wiping position.

[0077] Optionally, the friction member 200 is configured as a rubber block, and the bottom wall of the rubber block is configured to be inclined. In this way, when the cleaning body 20 is placed on the surface to be cleaned, the bottom of the rubber block will contact the surface to be cleaned to undergo elastic deformation, thereby ensuring that there is pressure between the friction member 200 and the surface to be cleaned to generate friction, thereby improving the reliability of the wiper device 10.

[0078] Among them, the friction part 200 can be a structure that can undergo elastic deformation as a whole, or a structure that can undergo elastic deformation in part, and can also be installed on the cleaning body 20 through a component that can undergo elastic deformation. It only needs to ensure that when the cleaning body 20 is placed on the surface to be cleaned, there is pressure between the friction part 200 and the surface to be cleaned so as to generate friction.

[0079] Specifically in this embodiment, the front side of the bottom wall is located above the rear side of the bottom wall.

[0080] like Figure 5 , Figure 6 and Figure 7 As shown, in one embodiment, there is at least one friction member 200 and at least one transmission assembly 300, each friction member 200 is mounted on the cleaning body 20 and is correspondingly connected to each transmission assembly 300, and each transmission assembly 300 is connected to the wiper member 100. In this way, by increasing the number of friction members 200 and transmission assemblies 300, the driving force received by the wiper member 100 is more evenly distributed, ensuring that the wiper member 100 can move smoothly along the first direction relative to the mounting bracket 400, thereby improving the reliability of the wiper device 10.

[0081] The number of friction members 200 and the number of transmission assemblies 300 can be flexibly adjusted according to actual use needs. Specifically in this embodiment, the number of friction members 200 and the number of transmission assemblies 300 are both two, and the two friction members 200 are arranged on the cleaning body 20 at intervals and are correspondingly connected to the two transmission assemblies 300. The two transmission assemblies 300 are correspondingly connected to the two ends of the wiper member 100.

[0082] In one embodiment, a cleaning device 30 is provided, comprising a cleaning body 20 and a wiper device 10 in any of the above embodiments, wherein the wiper device 10 is mounted on the cleaning body 20 .

[0083] The cleaning device 30 in the above embodiment uses the friction between the friction member 200 and the surface to be cleaned during the movement of the cleaning body 20 as a driving force, and selectively transmits the driving force to the wiper member 100 through the transmission assembly 300, so that the wiper member 100 does not wipe water during the forward push, and the wiper member 100 effectively wipes the water stains generated by the cleaning body 20 during the backward pull, thereby satisfying the user's overall habit of cleaning backwards and ensuring the cleaning effect of the cleaning device 30. In addition, the friction between the friction member 200 and the surface to be cleaned during the movement of the cleaning body 20 is used as a driving force, which has a simple structure and does not require a power source to drive. While the above technical effects are easily achieved, the cost of the cleaning device 30 is also reduced.

[0084] It should be noted that the present application takes the cleaning device 30 as a floor scrubber as an example for detailed description. In other embodiments, the cleaning device 30 may also be a floor sweeper or a floor mopping machine.

[0085] like Figure 2 , Figure 4 and Figure 7 As shown, further, the cleaning body 20 includes a roller brush 21 and a top shell 22, the top shell 22 is covered above the roller brush 21, and the wiper device 10 is installed at the front end of the top shell 22. In this way, the wiper device 10 is located at the front end of the roller brush 21, ensuring that the wiper member 100 can effectively wipe away the water stains generated when the roller brush 21 retreats when the cleaning body 20 is pulled back, thereby improving the cleaning effect of the cleaning device 30.

[0086] Specifically in this embodiment, the fourth sliding portion 201 and the buckle 202 are both disposed at the front end of the top shell 22 .

[0087] like Figure 2 and Figure 4As shown, optionally, the surface to be cleaned is set as the ground. The cleaning body 20 also includes an upper shell 23, a lower shell 24, a front push wiper 25, a power wheel 26 and a sewage suction port. The upper shell 23 is detachably connected to the lower shell 24, the top shell 22 is detachably connected to the front end of the upper shell 23, the roller brush 21 is located at the front end of the lower shell 24, the power wheel 26 is located at the rear end of the lower shell 24, and the front push wiper 25 is installed at the front end of the lower shell 24 and is used to scrape water stains on the ground. The working principle of the cleaning device 30 is as follows: the vacuum motor generates suction, and the clean water in the clean water tank is sprayed onto the roller brush 21 through the water pump. Driven by the motor of the roller brush 21, the roller brush 21 starts to rotate, generating friction with the ground, scraping up the dust and dirt on the ground, and dissolving them in the water to become sewage, which is sucked away through the sewage suction port. At the same time, the wiper parts 100 on the front and rear sides of the roller brush 21 and the front push wiper plate 25 scrape off the water stains on the ground. The power-assisted wheel 26 can realize forward and reverse rotation during the cleaning process, making forward pushing and backward pulling more labor-saving, thereby completing a cleaning cycle.
