[0003] In the existing cleaning equipment, when the user uses the cleaning equipment for cleaning, the user needs to install the roller brush in the cavity on the floor brush base.

However, in the existing cleaning equipment, the cavity where the roller brush is installed is often provided with a step structure, and the suction port is generally provided in a rectangular shape, which makes it easy for dirt to remain at the suction port or in the cavity. If you want to clean the suction port or the cavity, you need to rely on a special cleaning device, or perform manual cleaning. When performing manual cleaning, the user needs to manually pick up the roller brush handle first, which is time-consuming and labor-intensive, and affects the user experience.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. The cleaning equipment involved in the present application is described in detail below.

[0053] First embodiment

[0054] The first embodiment of the present application provides a cleaning device, and the cleaning device in the present application can be a handheld cleaning device, or a fully automatic cleaning device such as an automatic floor scrubber, or other cleaning devices equipped with a floor brush assembly. In a specific working scenario, the floor brush assembly installed on the cleaning device is mainly used to clean the contaminants attached to the surface to be cleaned, and the cleaning element in the floor brush assembly is used to directly contact the surface to be cleaned for cleaning.

[0055] With the advancement of technology, various smart home devices have further improved people's quality of life. Among them, as people pay more and more attention to environmental hygiene, cleaning equipment has become one of the most commonly used smart home devices.

[0056] In the existing cleaning equipment, when the user uses the cleaning equipment for cleaning, the user needs to install the roller brush in the cavity on the floor brush base. The roller brush can remove dry dirt and wet dirt on the surface to be cleaned, and then the dry dirt and wet dirt are sucked into the dust suction channel through the suction port. However, in the existing cleaning equipment, the cavity where the roller brush is installed is often provided with a step structure, and the suction port is generally provided in a rectangular shape, which makes it easy for dirt to remain at the suction port or in the cavity. If you want to clean the suction port or the cavity, you need to rely on a special cleaning device, or perform manual cleaning. When performing manual cleaning, the user needs to manually pick up the roller brush handle first, which is time-consuming and labor-intensive, and affects the user experience. Therefore, how to reduce the residual dirt at the suction port or in the cavity has become a technical problem to be solved.

[0057] In order to solve the above existing problems, the present application provides a cleaning device. The floor brush assembly of the cleaning device optimizes the specific structure of the sewage suction port, specifically setting the sewage suction port to a wide arc-shaped opening, and connecting the sewage suction port and the water scraper with a guide, and transitioning between the sewage suction port and the scraper with an arc structure, so that the sewage scraped from the roller brush by the water scraper and the sewage scraped from the surface to be cleaned by the scraper can be smoothly sucked into the sewage suction port. At the same time, since the shape of the sewage suction port is set to a wide arc-shaped opening, it is convenient for dirt to pass through the sewage suction port, thereby reducing the dirt residue at the sewage suction port and the cavity, and improving the user experience.

[0058] The floor brush assembly provided in the first embodiment of the present application is as follows: Figure 1 and Figure 8 As shown, Figure 1 A schematic diagram of the structure of a floor brush assembly of a cleaning device provided in the first embodiment, Figure 8 This is a schematic diagram of the overall structure of the cleaning device provided in the first embodiment.

[0059] In the present embodiment, the cleaning device includes a floor brush assembly, which includes: a cleaning element 11 and a floor brush base 12; the cleaning element 11 is rotatably mounted in a cavity 13 of the floor brush base 12; a sewage suction port 132 and a wiper 133 are provided on a cavity wall 131 of the cavity 13; the wiper 133 abuts against the cleaning element 11 to scrape the sewage on the cleaning element 11 when the cleaning element 11 rotates; the sewage suction port 132 is shaped as an arc-shaped wide mouth, and is connected to the wiper 133 through a guide 134, so that the sewage scraped by the wiper 133 is sucked into the sewage suction port 132 along the surface of the guide 134; the sewage suction port 132 is connected to a scraper bar 135, and the scraper bar 135 is used to contact the surface to be cleaned to scrape the sewage on the surface to be cleaned; the connection position of the sewage suction port 132 and the scraper bar 135 is transitioned in an arc structure, and the cleaning element 11 allows the sewage scraped by the scraper bar 135 to be sucked into the sewage suction port 132 along the surface of the arc structure.

[0060] In the floor brush assembly, the floor brush base 12 is the base of the floor brush assembly, which is used to install various functional components, such as various motors, sensors, pumps, pipes, cameras, etc., so that the floor brush assembly can realize the function of automatic cleaning. A roller 14 is arranged on the floor brush base 12. When cleaning the surface to be cleaned, the floor brush assembly needs to be placed on the surface to be cleaned. At this time, the cleaning element 11 and the roller 14 are in contact with the surface to be cleaned, and when the roller 14 drives the floor brush assembly to move, the cleaning element 11 sweeps away the dirt on the surface to be cleaned.

[0061] The cleaning element 11 can be a specific structure for cleaning, such as a roller brush, and the cleaning element 11 can be rotatably installed in the cavity 13 of the floor brush base 12. The cleaning element 11 can be set in different structural forms as required, such as a solid cylinder, a cylinder, etc. In addition, a felt surface, a collodion surface, etc. can be set on the surface of the cleaning element 11, so that the cleaning element 11 has different cleaning capabilities, which is not specifically limited here.

[0062] The cavity 13 refers to the installation space reserved for the cleaning element 11 on the floor brush base 12, and is used to install and accommodate the cleaning element 11. The spatial structure of the cavity 13 has many structural forms.

[0063] In a preferred embodiment, the cleaning element 11 can be set as a roller brush, and the cavity 13 can be set as a cylindrical space corresponding to the cleaning element 11, and the axis of the cylindrical space is collinear with the axis of the cleaning element 11 installed in the cavity 13. In order to allow the cleaning element 11 to rotate freely, a preset distance is set between the cleaning element 11 and the cavity wall 131 of the cavity 13, so that an arc-shaped gap is formed between the cleaning element 11 and the cavity 13, thereby leaving space for scraping the sewage. The value of the preset distance depends on the specific needs and is not limited here. The sewage includes both liquid and solid sewage.

[0064] The scraper 133 is arranged on the cavity wall 131 of the cavity 13 and is always in contact with the cleaning element 11 to scrape the dirty water on the cleaning element 11 when the cleaning element 11 rotates. Specifically, the scraper 133 is generally arranged as a rigid long plate, and the first end is fixed on the cavity wall 131 of the cavity 13, and the second end is in contact with the cleaning element 11. When cleaning the surface to be cleaned, the roller 14 drives the floor brush base 12 to move, and the cleaning element 11 moves on the surface to be cleaned and rotates accordingly. When the cleaning element 11 rotates, the scraper 133 rubs against the outer surface of the cleaning element 11 and squeezes the cleaning element 11, thereby scraping the dirty water adsorbed on the outer surface of the cleaning element 11.

[0065] The scraper bar 135 is arranged on the floor brush base 12 and connected to the sewage suction port 132. In addition, the scraper bar 135 is arranged such that when the floor brush assembly is placed on the surface to be cleaned, the scraper bar 135 contacts the surface to be cleaned. When cleaning the surface to be cleaned, the roller 14 drives the floor brush base 12 to move, and the scraper bar 135 moves with the movement of the floor brush base 12, and always contacts the surface to be cleaned during the movement, so as to scrape the sewage on the surface to be cleaned.

[0066] The sewage suction port 132 is arranged on the cavity wall 131 of the cavity 13, specifically, the sewage suction port 132 is between the wiper plate 133 and the scraper strip 135. The sewage suction port 132 is connected to the first end of the sewage suction pipe 138, and the second end of the sewage suction pipe 138 is connected to the sewage tank, and the second end of the sewage suction pipe 138 (the sewage suction pipe 138 actually corresponds to the dust suction channel) is provided with a sewage suction power part such as a water pump to provide power for sucking sewage. When sucking sewage, the sewage suction power part is started, and the sewage suction port 132 will generate wind pressure (which can be negative pressure) to suck sewage, so that the sewage is sucked and flows into the sewage suction port 132, and flows through the sewage suction pipe 138 and finally flows into the sewage tank.

[0067] In this embodiment, the wiper plate 133, the scraper bar 135, and the sewage suction port 132 are mutually coordinated structures. Specifically, when the floor brush assembly is placed on the surface to be cleaned, the cleaning element 11 and the scraper bar 135 are in contact with the surface to be cleaned. When the roller 14 moves, the cleaning element 11 rotates accordingly, and the wiper plate 133 scrapes off the sewage adsorbed by the cleaning element 11. The scraper bar 135 also scrapes off the sewage on the surface to be cleaned as the floor brush base 12 moves. All the scraped sewage is concentrated in the arc-shaped gap between the cleaning element 11 and the cavity 13. When the roller 14 moves, the sewage suction port 132 generates wind pressure, so that the sewage in the arc-shaped gap is sucked and flows into the sewage suction port 132.

[0068] In this embodiment, the sewage suction port 132 is set to be an arc-shaped wide mouth, and is transitionally connected with the wiper plate 133 and the scraper strip 135 respectively. The arc-shaped wide mouth means that the size of the outer end opening of the sewage suction port 132 close to the cleaning element 11 is larger than the size of the inner end opening of the sewage suction port 132 close to the sewage suction pipe 138, and the outer end opening and the inner end opening adopt an arc transition. In other words, the arc-shaped wide mouth is a trumpet-shaped opening, and the inner wall of the trumpet-shaped opening is an arc curve, and the opening side with a larger size is aligned with the cleaning element 11. The design of the arc-shaped wide mouth can make the sewage suction port 132 cover a wider suction range, and when the sewage flows into the sewage suction pipe 138 through the arc-shaped wide mouth, the dirt in the sewage will not remain too much at the sewage suction port 132.

[0069] The sewage suction port 132 and the wiper plate 133 are connected by a guide 134, so that the sewage scraped by the water hanging plate can flow to the sewage suction port 132 along the guide 134. In addition, the guide 134 is preferably set to an arc shape so that the guide 134 can better fit the wiper plate 133 and the cavity wall 131 of the cavity 13.

[0070] In this embodiment, the connection position between the cleaning element 11 and the scraper bar 135 is also set to an arc structure, so that a smooth transition can be achieved between the cleaning element 11 and the scraper bar 135, so that the sewage scraped by the scraper bar 135 can flow unimpeded into the sewage suction port 132 along the arc structure, and dirt is prevented from remaining at the connection position between the cleaning element 11 and the scraper bar 135.

[0071] The arrangement of the guide member 134 and the arc structure also enables the wind pressure generated by the sewage suction port 132 to fully act on the arc-shaped gap between the cleaning element 11 and the cavity 13, so that any point in the arc-shaped gap is affected by the wind pressure, thereby enabling the sewage to be fully sucked into the sewage suction port 132, and further avoiding dirt from remaining on the cavity wall 131 of the cavity 13.

[0072] In the floor brush assembly, since the dirty water scraped from the cleaning element 11 by the wiper 133 and the dirty water scraped from the surface to be cleaned by the scraper bar 135 can be smoothly sucked into the sewage suction port 132, the residual dirt in the cavity 13 is greatly reduced, and the cleaning frequency of the floor brush base 12 is also reduced, thereby improving the user experience.

[0073] In the floor brush assembly, the wiper 133 can always abut against the outer surface of the cleaning element 11. If the installation position or installation angle of the wiper 133 is different, the abutment angle between the wiper 133 and the outer surface of the cleaning element 11 will also be different, and the ability of the wiper 133 to scrape sewage will also be different. Among them, the wiper 133 can be set to be tangent to the outer surface of the cleaning element 11, and the wiper 133 can also be set to be at a preset angle with the cross section of the outer surface of the cleaning element 11, which is not limited here. In addition, a pre-tightening element such as a spring can be set on the wiper 133, so that the wiper 133 can always reliably abut against the cleaning element 11 under the action of the pre-tightening element.

[0074] In one embodiment, the cleaning element 11 will also exert a thrust on the wiper plate 133 to push the wiper plate 133 away during the rotation process. Therefore, in order to prevent the cleaning element 11 from pushing the wiper plate 133 away during the rotation and reducing the effect of the wiper plate 133 in scraping the sewage, in one embodiment, it can be seen that Figure 2 , Figure 2The schematic diagram of the position of the water scraper of the floor brush assembly provided in the first embodiment is as follows: The water scraper 133 is perpendicular to the cut surface of the outer surface of the cleaning element 11 , so that the direction in which the water scraper 133 scrapes the sewage is tangent to the outer surface of the cleaning element 11 .

[0075] In this embodiment, the wiper 133 is perpendicular to the tangent plane of the outer surface of the cleaning element 11, so that the line of action of the wiper 133 on the cleaning element 11 passes through the axis of the cleaning element 11. When the cleaning element 11 rotates, the line of action of the friction force between the wiper 133 and the cleaning element 11 is tangent to the outer surface of the cleaning element 11, and the scraping direction of the sewage is consistent with the direction of the friction force, so that the scraping direction of the sewage is also tangent to the outer surface of the cleaning element 11. At this time, although the cleaning element 11 rotates, the force of the cleaning element 11 on the wiper 133 is only the friction between the two, which makes it difficult for the cleaning element 11 to push the wiper 133 away, so that the wiper 133 can fully scrape the sewage when the cleaning element 11 rotates, thereby fully ensuring the effect of the wiper 133 scraping the sewage.

[0076] In the floor brush assembly, in order to ensure the suction effect of the suction port 132, the suction port 132 is set to be a wide arc-shaped opening. In order to improve the suction capacity of the suction port 132, the shape of the suction port 132 can be set to an ellipse, and the major axis of the ellipse is parallel to the axis of rotation of the cleaning element 11 (such as the axis of the roller brush), the minor axis of the ellipse is perpendicular to the axis of rotation of the cleaning element 11, and the length of the minor axis is set to a first preset length.

[0077] When the sewage suction port 132 is set to be an ellipse, the lengths of the major axis and the minor axis of the ellipse determine the size of the sewage suction port 132. The lengths of the major axis and the minor axis of the ellipse can be determined according to specific needs, and in order to reduce the volume of the floor brush assembly, in this embodiment, the major axis of the ellipse is parallel to the axis of the cleaning element 11.

[0078] When determining the size of the sewage suction port 132, the length of the short axis can be first determined as the first preset length, and then the length of the long axis can be determined. For example, when determining the size of the sewage suction port 132, the length of the short axis can be set to 19 mm, and then the length of the long axis can be further determined based on parameters such as the length of the axis of the cleaning element 11, the contact length between the wiper 133 and the cleaning element 11, and the contact length between the scraper 135 and the surface to be cleaned.

[0079] The reason why the sewage suction port 132 is set to be elliptical is to shorten the distance that the sewage near the two ends of the cleaning element 11 needs to pass when flowing into the sewage suction port 132, so as to ensure the sewage suction effect of the sewage suction port 132. At the same time, when the elliptical sewage suction port 132 generates wind pressure for suctioning sewage, the wind pressure near the two ends of the cleaning element 11 is also greater, and the traction force on the sewage is also greater, and then the speed at which the sewage flows into the sewage suction port 132 is also faster, so that the sewage suction effect of the sewage suction port 132 can be further improved.

[0080] In another embodiment, in order to improve the sewage suction effect of the sewage suction port 132, the structure of the cavity wall 131 of the cavity 13 can be set to be concave toward the sewage suction port 132, and the distance between the outer surface of the cleaning element 11 and the cavity wall 131 of the cavity 13 is set between the first preset value and the second preset value.

[0081] In this embodiment, the cavity wall 131 of the cavity 13 is actually set as an inclined surface, and the inclined surface is inclined to the sewage suction port 132, so that the distance from the two ends of the cleaning element 11 to the cavity wall 131 is smaller than the distance from the middle position of the cleaning element 11 to the cavity wall 131. When the sewage suction port 132 starts to suck sewage, the sewage at both ends of the cleaning element 11 will flow to the sewage suction port 132 along the cavity wall 131 of the cavity 13 under the wind pressure of the sewage suction port 132. In this process, the cavity wall 131 guides the sewage. At the same time, because the cavity wall 131 of the cavity 13 is inclined to the sewage suction port 132, the cavity wall 131 can constitute an extension of the arc-shaped wide mouth of the sewage suction port 132, so that the wind pressure effect of the sewage suction port 132 to suck sewage is stronger, thereby further improving the sewage suction effect of the sewage suction port 132.

[0082] In this embodiment, the numerical range between the first preset value and the second preset value corresponds to the distance range from the outer surface of the cleaning element 11 to the cavity wall 131, and the first preset value and the second preset value can be set to different values ​​according to specific needs. For example, in one embodiment, the first preset value can be set to 4.5 mm, and the second preset value can be set to 6.5 mm, so that the shortest distance from both ends of the outer surface of the cleaning element 11 to the cavity wall 131 is 4.5 mm, and the shortest distance from the cleaning element 11 to the center point of the suction port is 6.5 mm.

[0083] In addition, in order to allow the sewage sucked to the sewage suction port 132 to smoothly enter the sewage tank, the sewage suction pipe 138 can be set as a smooth pipe. In one embodiment, the sewage suction port 132 is connected to the sewage tank through the sewage suction pipe 138, and the sewage suction pipe 138 is set as a hose so that the sewage sucked into the sewage suction pipe 138 can be smoothly sucked into the sewage tank.

[0084] In this embodiment, the position where the hose connects to the sewage suction port 132 is set to be a smooth arc. After the sewage enters the sewage suction pipe 138, the water level will not rise instantly, so the wind pressure requirement for sewage suction is not high, and the sucked sewage is not easy to flow back from the sewage suction pipe 138 to the sewage suction port 132 and flow out, thereby avoiding secondary contamination of the cleaned cleaning surface.

[0085] The structure described above is a basic structure of the floor brush assembly provided in this embodiment. The floor brush assembly sets the sewage suction port as an arc-shaped wide mouth, and the sewage suction port and the wiper are connected and transitioned by a guide, and the sewage suction port and the scraper are transitioned by an arc structure, so that the sewage scraped from the cleaning element by the wiper and the sewage scraped from the surface to be cleaned by the scraper can be smoothly sucked into the sewage suction port, thereby reducing the dirt residue in the cavity and at the sewage suction port, and there is no need to frequently clean the cavity and the sewage suction port.

[0086] The above structure is mainly aimed at optimizing the structure of the dirt suction part of the floor brush assembly, and by improving the dirt suction effect of the dirt suction part structure and reducing the dirt residue, the purpose of reducing the cleaning frequency of the dirt suction part structure is achieved. In addition to this optimization method, this embodiment can also improve the above basic structure on the basis of the above-mentioned floor brush assembly structure, or add other feasible structures to the basic structure to obtain more functions or performances to meet the needs of different application scenarios. The following is a specific introduction to the two improvements to the basic structure. Of course, it can be understood that the two improvements to the basic structure can be separate or simultaneous, and no limitation is made here.

[0087] The first implementation method for improving the basic structure is to configure the cleaning element and the cavity wall to be a structure that can move relative to each other, so as to improve the cleaning method of the floor brush base.

[0088] In the existing floor brush assembly, the method of cleaning the floor brush base mainly relies on a special cleaning device, or is cleaned manually.

[0089] This embodiment provides a self-cleaning floor brush assembly structure based on the above basic structure to achieve automatic cleaning of the floor brush base.

[0090] Specifically, the cleaning element 11 and the cavity wall 131 can move relative to each other, and the cleaning element 11 or the cavity wall 131 can reciprocate between a position where the cleaning element 11 and the cavity wall 131 are in contact with each other and a position where the cleaning element 11 and the cavity wall 131 are a preset distance apart.

[0091] Among them, the cleaning element 11 and the cavity wall 131 are structures that can move relative to each other. In a specific embodiment, the cavity wall 131 can be fixed relative to the floor brush base 12, while the cleaning element 11 can move relative to the floor brush base 12, thereby realizing the relative movement of the cleaning element 11 and the cavity wall 131. Specifically, the cleaning element 11 can be movably arranged on the floor brush base 12, and the cleaning element 11 can reciprocate between the first position and the second position; when the cleaning element 11 is in the first position, the cleaning element 11 and the cavity wall 131 maintain a preset distance; when the cavity wall 131 is in the second position, the cleaning element 11 and the cavity wall 131 are in contact.

[0092] The cavity wall 131 may also be arranged to be movable relative to the floor brush base 12, while the cleaning element 11 is fixed relative to the floor brush base 12, so as to achieve relative movement of the cleaning element 11 and the cavity wall 131. Specifically, the cavity wall 131 may be movably arranged on the floor brush base 12, and the cavity wall 131 may reciprocate between the third position and the fourth position; when the cavity wall 131 is located at the third position, the cleaning element 11 maintains a preset distance from the cavity wall 131; when the cavity wall 131 is located at the fourth position, the cleaning element 11 fits against the cavity wall 131.

[0093] Of course, the cleaning element 11 and the cavity wall 131 may also be configured as a structure that can move relative to the floor brush base 12, and no specific limitation is made here.

[0094] Furthermore, a driving device (such as a motor) may be further provided to drive the cleaning element 11 or the cavity wall 131 , thereby achieving relative movement between the cleaning element 11 and the cavity wall 131 .

[0095] For example, taking the embodiment in which the cavity wall 131 is fixed relative to the floor brush base 12 and the cleaning element 11 is movable relative to the floor brush base 12 as an example, the floor brush assembly of this embodiment is as follows: Figure 3 , Figure 4 and Figure 5 As shown, Figure 3 A schematic diagram of the structure of a floor brush assembly provided with a cleaning element displacement device provided in the first embodiment, Figure 4 This is a schematic structural diagram of a cleaning element of a floor brush assembly provided in the first embodiment when the cleaning element is located in a first position. Figure 5 A schematic structural diagram of the cleaning element of the floor brush assembly provided in the first embodiment when it is located in the second position.

[0096] In this embodiment, the floor brush assembly also includes: a cleaning element handle 15 and a cleaning element displacement device 16; the cleaning element handle 15 is connected to the end of the cleaning element 11 to provide rotational support for the cleaning element 11, so that the cleaning element 11 can be rotatably installed in the cavity 13 of the floor brush base 12; the cleaning element handle 15 is transmission-connected to the cleaning element displacement device 16, and the cleaning element handle 15 drives the cleaning element 11 to reciprocate between the first position and the second position under the push-pull action of the cleaning element displacement device 16; when the cleaning element 11 is in the first position, it maintains a preset distance from the cavity wall 131 of the cavity 13; when the cleaning element 11 is in the second position, it fits against the cavity wall 131 of the cavity 13.

[0097] In this embodiment, in addition to setting the sewage suction port 132 as a wide arc-shaped opening, connecting the sewage suction port 132 and the wiper 133 with a guide 134, and transitioning the sewage suction port 132 and the scraper 135 with an arc structure, the relevant structure of the cleaning element 11 is further set so that the cleaning element 11 can reciprocate between the first position and the second position, so that the cleaning element 11 can clean the sewage suction port of the floor brush base 12 by changing the position of the cleaning element 11.

[0098] The cleaning element handle 15 is a structure for installing the cleaning element 11 in the cavity 13, and a support structure for providing rotation support for the cleaning element 11 is provided on the cleaning element handle 15. The cleaning element 11 and the cleaning element handle 15 are an integrated structure. When the cleaning element 11 needs to be installed on the floor brush base, the user only needs to hold the cleaning element handle 15 to install the cleaning element 11 into the cavity 13 of the floor brush base 12. When the cleaning element needs to be removed from the floor brush base, force can be directly applied to the cleaning element handle 15 to remove the cleaning element from the floor brush base.

[0099] The cleaning element displacement device 16 is a structure that is in transmission connection with the cleaning element handle 15 and provides a push-pull force for the cleaning element handle 15. When the cleaning element handle 15 is subjected to the force provided by the cleaning element displacement device 16, the force is simultaneously applied to the cleaning element 11, so that the cleaning element 11 can move back and forth between the first position and the second position.

[0100] It should be clear that the first position and the second position are the positions of the cleaning element 11 relative to the floor brush base. The first position refers to the position where the cleaning element 11 maintains a preset distance from the cavity wall 131 of the cavity 13, and the second position refers to the position where the cleaning element 11 fits the cavity wall 131 of the cavity 13. When cleaning the surface to be cleaned, the cleaning element 11 needs to be placed in the first position. When cleaning the position of the suction port 132, the cleaning element 11 needs to be placed in the second position.

[0101] Before a user uses the floor brush assembly provided with the cleaning element displacement device 16 to clean the surface to be cleaned, the user needs to first push the cleaning element 11 to the first position through the cleaning element displacement device 16. When cleaning the surface to be cleaned, the cleaning element 11 rotates, and the dirt suction port 132 sucks the dirt on the cleaning element. After cleaning the surface to be cleaned, if the position of the dirt suction port 132 is to be self-cleaned, the cleaning element 11 only needs to be pulled to the second position using the cleaning element displacement device 16.

[0102] In this embodiment, the position of the cleaning element 11 can be adjusted to clean the sewage suction port or the surface to be cleaned, that is, this embodiment switches the position of the cleaning element 11 so that the floor brush assembly has a cleaning mode for cleaning the surface to be cleaned and a self-cleaning mode for cleaning the sewage suction port 132, and can continue to switch between the two modes, thereby improving the user experience.

[0103] In addition, in this type of floor brush assembly, the cleaning element displacement device 16 also has many specific settings. Specifically, the cleaning element displacement device 16 can be set to a manual push-pull structure, or it can be set to an automatic push-pull structure. In order to achieve the automatic cleaning function, it is preferred that the cleaning element displacement device 16 is set to an automatic push-pull structure.

[0104] Specifically, the cleaning element displacement device 16 includes a first power member 161 and a first push rod 162; the first end of the first push rod 162 is transmission connected to the first power member 161, and the second end of the first push rod 162 is transmission connected to the cleaning element handle 15; the first push rod 162 pushes the cleaning element 11 to the first position when the first power member 161 provides thrust, and pulls the cleaning element 11 to the second position when the first power member 161 provides pulling force.

[0105] The first power member 161 provides a push-pull force for the first push rod 162 , so that the first push rod 162 pushes and pulls the cleaning element handle 15 , thereby providing a push-pull force for the cleaning element handle 15 .

[0106] The first power member 161 can be controlled by the control element to provide a push or pull force. Specifically, the control element can be set as a control module, so that the floor brush assembly can automatically enter the cleaning mode or the self-cleaning mode, thereby realizing the fully automatic switching between the cleaning mode and the self-cleaning mode. The control member can also be set as a control button. When the user triggers the control button, the first power member 161 starts, thereby providing a push and pull force to the first push rod 162, so that the floor brush assembly enters the cleaning mode or the self-cleaning mode through user operation, thereby realizing the semi-automatic switching between the cleaning mode and the self-cleaning mode.

[0107] Of course, the first power member 161 can also be controlled by the control module and the control button at the same time, so that the floor brush assembly can enter the cleaning mode or the self-cleaning mode in an automatic control mode, and can also enter the cleaning mode or the self-cleaning mode in a semi-automatic control mode. Of course, the control priority of the control button can be set higher than the control priority of the control module, so as to facilitate user operation.

[0108] The specific structure of the first power member 161 can also be selected in many ways, such as being set as a motor or a pump. Taking the first power member 161 as a motor as an example, the specific structure of the cleaning element displacement device 16 can be set as follows: when the first power member 161 is set as a motor, the first end of the first push rod 162 is threadedly connected to the output shaft of the motor, so that the first push rod 162 pushes and pulls the cleaning element handle 15 as the output shaft of the motor rotates.

[0109] In this structure, the first end of the first push rod 162 is threadedly connected to the output shaft of the motor. When the output shaft of the motor rotates, if the rotation direction causes the second end of the first push rod 162 to continuously approach the output shaft of the motor, then the motor provides a pulling force for the first power member 161; if the rotation direction causes the second end of the first push rod 162 to continuously move away from the output shaft of the motor, then the motor provides a thrust for the first power member 161.

[0110] In addition, since the wiper plate 133 is in contact with the cleaning element 11 , in order to enable the cleaning element 11 to move smoothly between the first position and the second position, the wiper plate 133 may also be configured to be a structure that can move with the movement of the cleaning element 11 .

[0111] Specifically, Figure 4 and Figure 5 As shown, the cavity wall 131 of the cavity 13 is provided with a slide groove 136, and the wiper 133 is inserted into the slide groove 136 under the thrust of the supporting member 137; when the cleaning element 11 is located in the first position, the wiper 133 is extended out of the slide groove 136 and abuts against the cleaning element 11 by the action of the supporting member 137; when the cleaning element 11 is located in the second position, the wiper 133 overcomes the action of the supporting member 137 under the abutting action of the cleaning element 11 and retracts into the slide groove 136.

[0112] In this structure, the wiper 133 is inserted into the slide groove 136 and is always pushed by the top holding member 137. When the cleaning element 11 is in the first position, the wiper 133 is always in contact with the cleaning element 11 under the action of the top holding member 137, and the force of the top holding member 137 enables the wiper 133 to always be against the cleaning element 11 when the cleaning element 11 rotates, thereby ensuring the effect of the wiper 133 in scraping the sewage.

[0113] When the cleaning element 11 moves from the first position to the second position under the push-pull action of the cleaning element moving device 16, since the cleaning element 11 and the wiper 133 are in contact with each other, the wiper 133 is simultaneously subjected to the thrust of the supporting member 137 and the abutment of the cleaning element 11. Since the force provided by the cleaning element moving device 16 is greater than the thrust of the supporting member 137, the wiper 133 overcomes the force of the supporting member 137 under the abutment force of the cleaning element 11 and retracts into the slide groove 136.

[0114] When the cleaning element 11 moves from the second position to the first position under the push-pull action of the cleaning element moving device 16, the cleaning element 11 will gradually move away from the cavity wall 131 of the cavity 13 during the movement, and the wiper 133 will gradually extend out of the slide groove 136 under the thrust of the supporting member and always maintain contact with the cleaning element 11 until the cleaning element 11 moves to the second position.

[0115] In this embodiment, the supporting member 137 always provides thrust for the wiper 133, and does not affect the movement of the wiper 133. In a specific embodiment, the supporting member 137 can be set as a spring. Alternatively, a magnet can be set as the supporting member 137 to provide thrust for the wiper 133. Of course, other feasible structures can also be set as the supporting member 137, which is not limited here.

[0116] In this type of cleaning device in which the cleaning element and the cavity wall are arranged to move relative to each other, the dirt suction component (such as the dirt suction port or the cavity) on the floor brush assembly not only has a good dirt suction effect, but also can adjust the relative position of the cleaning element and the cavity wall so that the floor brush assembly also has a self-cleaning mode, thereby improving the user experience.

[0117] The second implementation method for improving the basic structure is to provide a structure that can automatically lift up the handle of the cleaning element to improve the disassembly method of the cleaning element.

[0118] In the existing floor brush assembly, the cleaning element 11 is installed in the cavity 13 of the floor brush base 12 through the cleaning element handle 15. When the cleaning element 11 needs to be removed, the user needs to manually apply force to lift the cleaning element handle 15 from the floor brush assembly to achieve the purpose of removing the cleaning element 11.

[0119] This embodiment provides a floor brush assembly structure capable of automatically lifting the cleaning element handle based on the above-mentioned basic floor brush assembly.

[0120] Specifically, see Figure 6 , Figure 6 A schematic structural diagram of a floor brush assembly provided with a second power member provided in the first embodiment.

[0121] In this embodiment, the floor brush assembly also includes: a cleaning element handle 15; a groove 17 is provided on the side of the floor brush base 12; the cleaning element handle 15 is snapped into the groove 17 and connected to the end of the cleaning element 11 to provide rotational support for the cleaning element 11, so that the cleaning element 11 can be rotatably installed in the cavity 13 of the floor brush base 12; a second power member 181 and a second push rod 182 are provided on the floor brush base 12, the first end of the second push rod 182 is transmission-connected to the second power member 181, and the second end of the second push rod 182 abuts against the cleaning element handle 15; when the cleaning element 11 is disassembled, the second push rod 182 is pushed by the second power member 181 to push the cleaning element handle 15 out of the groove 17.

[0122] In this embodiment, in addition to setting the sewage suction port 132 as a wide arc-shaped mouth, and connecting the sewage suction port 132 and the wiper plate 133 with a guide member 134, and transitioning between the sewage suction port 132 and the scraper strip 135 with an arc structure, the relevant structure of the cleaning element handle 15 is further set, so that the cleaning element handle 15 can be pushed out of the groove 17 for installing the cleaning element handle 15 by the second power member 181, and there is no need to manually pick up the cleaning element handle 15.

[0123] Specifically, a snap-fit ​​structure or a magnetic structure is provided between the cleaning element handle 15 and the floor brush base 12 , so that the cleaning element handle 15 will not separate from the floor brush base 12 along the axial direction of the cleaning element 11 when the cleaning element 11 is installed on the floor brush base 12 .

[0124] In this embodiment, the line of action of the pushing force of the second power member 181 and the second push rod 182 on the cleaning element handle 15 is parallel to the axis of the cleaning element 11 , and the direction of the force is away from the floor brush base 12 .

[0125] When using the floor brush base 12 of this structure, when the user installs the cleaning element 11, he only needs to hold the cleaning element handle 15 to insert the cleaning element 11 into the cavity 13 of the floor brush base 12. When the cleaning element 11 is inserted into the cavity 13, the cleaning element handle 15 just fits into the groove 17.

[0126] When the user wants to take out the cleaning element 11, he only needs to start the second power member 181 so that the second power member 181 provides a driving force for the second push rod 182, and the second push rod 182 will push the cleaning element handle 15 out of the groove 17. The user can directly take the cleaning element handle 15 to remove the cleaning element 11 without having to pick out the cleaning element handle 15.

[0127] When the user installs the cleaning element 11, it is only necessary to align the cleaning element 11 with the cavity 13 and install it. During the installation process, the cleaning element handle 15 will push against the second push rod 182 and snap into the groove 17. At this time, the second push rod 182 has completed the reset process and can push the cleaning element handle 15 out of the groove 17 again when the cleaning element 11 is disassembled next time.

[0128] The specific arrangement of the second power member 181 and the second push rod 182 can refer to the arrangement of the first power member 161 and the first push rod 162. Exemplarily, the second power member 181 can also be similar to the first power member 161 and be set as a motor or a pump. At the same time, the transmission connection between the second power member 181 and the second push rod 182 can also be set as a threaded connection. Of course, the second power member 181 and the second push rod 182 can also be set in other ways, again without limitation.

[0129] For example, see Figure 7 , Figure 7 A partial schematic diagram of the position of the second power member of the floor brush assembly provided in the first embodiment. Specifically, a sleeve 183 is provided on the cleaning element handle 15, and the sleeve 183 is sleeved outside the second push rod 182 and abuts against the second push rod 182, so that the thrust of the second push rod 182 is transmitted to the cleaning element handle 15 through the sleeve 183. The sleeve 183 is provided to make the thrust of the second push rod 182 act more evenly on the cleaning element handle 15, so that the cleaning element handle 15 can be easily ejected.

[0130] The floor brush assembly provided with the second power part not only has the dirt suction components (such as the dirt suction port) on the floor brush assembly having a good dirt suction effect, but also makes the disassembly process of the cleaning element more convenient, further improving the user experience.

[0131] The floor brush assembly provided by the present application is introduced in detail above. Since the sewage suction port is set to a wide arc-shaped mouth, and the sewage suction port and the wiper are connected and transitioned by a guide, and the sewage suction port and the scraper are transitioned by an arc structure, the sewage scraped from the cleaning element by the wiper, and the sewage scraped from the surface to be cleaned by the scraper can be smoothly sucked into the sewage suction port, thereby reducing the dirt residue at the sewage suction port and the cavity, and reducing the cleaning frequency of the sewage suction component on the floor brush base. In a preferred embodiment, the cleaning element can be further made to fit with the cavity wall of the cavity, so as to self-clean the sewage suction port. In another preferred embodiment, the cleaning element handle can be further made to be automatically pushed out of the groove accommodating the cleaning element handle, so as to facilitate the automatic disassembly of the cleaning element, so as to further enhance the user experience.

[0132] Second embodiment

[0133] The second embodiment of the present application also provides a second cleaning device.

[0134] The cleaning device provided in this embodiment includes a floor brush assembly, which includes: a cleaning element and a floor brush base. The cleaning element is installed in a cavity of the floor brush base; the cleaning element and the cavity wall of the cavity can move relative to each other, and the cleaning element or the cavity wall can reciprocate between a position where the cleaning element fits the cavity wall and a position where the cleaning element and the cavity wall are at a preset distance.

[0135] The specific structure of the floor brush assembly in this type of cleaning device can refer to the relevant content of the first implementation method of the first embodiment for improving the basic structure, and will not be described in detail here.

[0136] For example, the floor brush assembly of this type of cleaning equipment can refer to Fig. 9 , Fig. 9 A schematic structural diagram of some components on the floor brush base of the floor brush assembly provided in the second embodiment.

[0137] Specifically, the floor brush assembly of the cleaning equipment includes: a cleaning element, a cleaning element handle, a cleaning element displacement device 16 and a floor brush base 12; the cleaning element handle is connected to the end of the cleaning element to provide a rotating support for the cleaning element so that the cleaning element can be rotatably installed in the cavity of the floor brush base 12; the cleaning element handle is transmission-connected to the cleaning element displacement device 16, and the cleaning element handle drives the cleaning element to reciprocate between a first position and a second position under the push-pull action of the cleaning element displacement device 16; when the cleaning element is in the first position, it maintains a preset distance from the cavity wall 131 of the cavity; when the cleaning element is in the second position, it fits against the cavity wall 131 of the cavity.

[0138] It should be clear that the difference between this embodiment and the first embodiment is that the floor brush assembly of this embodiment only includes a structure that enables the cleaning element to move relative to the cavity wall of the cavity (such as a roller brush displacement device and a roller brush handle that cooperates with the roller brush displacement device) and the components mentioned in the second embodiment, and the sewage suction port 132 is not necessarily set to the same structure as the first embodiment.

[0139] In the floor brush assembly of the cleaning device of this embodiment, the cleaning element and the cavity wall of the cavity can move relative to each other, so that it can freely switch between the cleaning mode for cleaning the surface to be cleaned and the self-cleaning mode for cleaning the sewage suction port, thereby realizing automatic self-cleaning of the sewage suction port and improving the user experience.

[0140] Third embodiment

[0141] The third embodiment of the present application also provides a third cleaning device.

[0142] The cleaning device comprises: a cleaning element, a cleaning element handle and a floor brush base; a groove is arranged on the side of the floor brush base; the cleaning element handle is buckled in the groove and connected with the end of the cleaning element to provide rotation support for the cleaning element, so that the cleaning element can be rotatably installed in the cavity of the floor brush base; a second power member and a second push rod are arranged on the floor brush base, the first end of the second push rod is transmission-connected with the second power member, and the second end of the second push rod abuts against the cleaning element handle; when the cleaning element is disassembled, the second push rod is pushed by the second power member to push the cleaning element handle out of the groove.

[0143] The specific structure of the floor brush assembly in this cleaning device can refer to the relevant content of the second embodiment of the improvement of the basic structure in the first embodiment, and no redundant description is given here. It should be clear that the difference between this embodiment and the first embodiment is that the floor brush assembly of this embodiment may only include the second power member and the second push rod structure and the related structures mentioned in the third embodiment, and the same structure as the first embodiment may not be provided at the sewage suction port.

[0144] In the cleaning device of this embodiment, the cleaning element handle of the floor brush assembly can be pushed out of the groove accommodating the cleaning element handle by the second push rod under the driving force provided by the second power member, thereby avoiding the process of manually picking up the cleaning element handle, thereby making the removal process of the cleaning element easier. Moreover, in a preferred embodiment, the third embodiment can also be combined with the second embodiment to enhance the user experience of using the cleaning device equipped with the floor brush assembly.

[0145] It should be noted that, although several structures, components or units for realizing related functions are mentioned in the above detailed description, such division is not mandatory. In fact, according to the specific implementation of the present application, the features and functions of two or more structures, components or units described above can be concretized in one structure, component or unit. Conversely, the features and functions of one structure, component or unit described above can be further divided into multiple components, structures or units to be concretized.

[0146] Application Scenario 1

[0147] When the user uses the cleaning equipment to clean the surface to be cleaned, the rotation of the roller drives the floor brush base to move, and the roller brush cleans the floor as the roller rotates. The scraper blade scrapes the sewage on the roller brush as the roller brush rotates, and the scraper bar scrapes the sewage on the floor as the floor brush base moves. The sewage scraped by the scraper blade and the scraper bar is smoothly sucked into the sewage tank under the suction force of the sewage suction port.

[0148] Application Scenario 2

[0149] When the user uses the cleaning device to clean the surface to be cleaned, the roller brush is located at the first position, at which time the roller brush maintains a preset distance from the cavity wall. After the user uses the cleaning device to clean the surface to be cleaned for a period of time, the roller brush is moved from the first position to the second position through the roller brush displacement device, at which time the roller brush fits the cavity wall, and the rotation of the roller brush is controlled to achieve self-cleaning of the suction port of the cavity. Afterwards, the roller brush is moved from the second position to the first position through the roller brush displacement device, and the cleaning device is used again to clean the surface to be cleaned.

[0150] Application Scenario 3
