Description

TECHNICAL FIELD

[0001] The utility model relates to cleaning equipment technical field, in particular to a base and cleaning system for cleaning equipment. BACKGROUND

[0002] Taking a scrubber as an example, the scrubber cleans a surface to be cleaned by a cleaning member at the bottom of the scrubber. In the cleaning process, in order to improve the cleaning effect, water is sprayed to the cleaning member, so that the cleaning member performs wet cleaning. However, this also causes more water stains to remain on the surface to be cleaned. In order to reduce the problem of water stains, the scrubber on the market currently is provided with a lifting type scraping strip assembly at the front end of the cleaning member. However, after the cleaning work of the scrubber is completed and the base is self-cleaned, the cleaning member has a poor drying effect, which affects the next cleaning work and use experience. SUMMARY

[0003] In view of the above problems, the base and cleaning system for cleaning equipment provided by the embodiments of the present application are provided. The air outlet is formed between the flow guide wall of the air duct and the groove bottom wall of the cleaning groove, the position of the air outlet is lowered, the drying airflow can blow more to the cleaning member, and the self-cleaning effect of the cleaning equipment provided with the lifting type scraping strip at the front of the cleaning member is improved.

[0004] In order to achieve the above purpose, the embodiments of the present application provide the following technical solutions:

[0005] The first aspect of the present application provides a base for cleaning equipment, which is used for cleaning and drying a cleaning member of the cleaning equipment, and comprises:

[0006] A fan;

[0007] A base shell, which is provided with a cleaning groove for placing the cleaning member; the base shell is provided with an air duct, and an air outlet is formed between a flow guide wall of the air duct and a groove bottom wall of the cleaning groove, the air outlet communicates the air duct and the cleaning groove;

[0008] The fan is located in the air duct, and the airflow blown by the fan is blown out along the groove bottom wall of the cleaning groove to the cleaning member after passing through the air duct and the air outlet in sequence.

[0009] In the prior art, the air outlet is located on the front side of the cleaning member, although the cover is arranged above the cleaning member of the cleaning device, the cover can hinder the dirt from being thrown forward, but the cover covers a small area of the circumferential side of the cleaning member, the size of the air outlet can match the size of the circumferential side of the cleaning member which is not covered by the cover, and then the size of the air outlet is larger, and the airflow flowing out of the air outlet can directly blow to the cleaning member. However, for the cleaning device additionally provided with the lifting type strip assembly, even if the strip assembly is in the lifting position, the strip assembly covers a larger area on the front side of the cleaning member, and the strips in the strip assembly are located lower, if the air outlet of the base in the prior art is used for drying operation, only a small part of the airflow blown by the air outlet blows to the cleaning member, the airflow is wasted, and the drying effect is poor. In the embodiment of the present application, the air outlet is formed by the tank bottom wall and the flow guide wall, which reduces the position of the air outlet, so that the output airflow is not easily blocked by the shell of the brush assembly, and the airflow blown by the fan can reach the cleaning member more. The tank bottom wall participates in the formation of the air outlet, not only reduces the position of the air outlet, but also can guide the airflow flowing out of the air outlet to the bottom of the cleaning member, so as to timely take away the humid air at the bottom of the cleaning member, and further improve the drying effect.

[0010] Optionally, the cleaning member of the cleaning device is a rolling brush, and the tank bottom wall comprises a bearing part and a transverse extension part, the bearing part is used for placing the rolling brush and storing cleaning liquid;

[0011] The transverse extension part extends from the bearing part to the air duct, and the transverse extension part and the flow guide wall of the air duct form the air outlet; the height of the transverse extension part is higher than that of the bearing part, so that the liquid on the transverse extension part converges to the bearing part under the action of gravity.

[0012] Before drying, the cleaning member needs to be cleaned with cleaning liquid. During the cleaning process, the water distributor of the cleaning device sprays cleaning liquid, which preferentially collects in the lower bearing part and is not easily flowed to the higher transverse extension part, which can effectively prevent the cleaning liquid or the liquid such as sewage after cleaning from flowing back into the air outlet or the air duct through the transverse extension part, thereby reducing the influence of the cleaning liquid or the sewage on the air duct or the fan.

[0013] Moreover, in the prior art, the distance between the air outlet of the base and the front side of the brush is small, after the cleaning member is additionally provided with the strip assembly, the thickness of the front side of the cleaning member is increased, and the cleaning device placed on the base is easy to cause insufficient space on the front side of the cleaning member, the strip assembly is at risk of being damaged, and even the strip assembly may block the air outlet, further reducing the drying effect. In the embodiment of the present application, the transverse extension part is arranged to increase the distance between the air outlet and the front side of the brush, which can reduce the risk of damage to the strip assembly and the risk of blocking the air outlet, and ensure the drying effect.

[0014] Optionally, the lateral extension is less curved downward than the carrying portion.

[0015] The lateral extension is higher than the carrying portion, which makes the height difference between the lateral extension and the carrying portion; and the lateral extension is less curved downward, which means the lateral extension is more gentle, which is beneficial for guiding the air flow to the cleaning member, and the carrying portion is more likely to accumulate liquid. In this way, even if some liquid rushes forward to the lateral extension, it will be guided to the carrying portion, further reducing the risk of liquid backflow into the air outlet or air duct.

[0016] In some embodiments, the lateral extension includes an inclined top surface, which is inclined from low to high from the carrying portion to the air outlet direction, so as to better prevent liquid backflow and better guide liquid to the carrying portion.

[0017] Optionally, the depth of the groove bottom wall in the vertical direction is less than 1 / 3 of the radius of the roller brush.

[0018] The cleaning tank is shallow, and the groove bottom wall is gentle, which can reduce the resistance of the fluid passing through, and is more conducive to guiding the air flow blowing out of the air outlet.

[0019] Optionally, the cleaning tank further includes a longitudinal extension located in the air duct, and the flow guide wall cover is arranged on the longitudinal extension and maintains a gap, the longitudinal extension extends upward from the position of the lateral extension, and forms a turning flow channel with the flow guide wall, the turning flow channel is configured to adjust the air flow direction in the air duct to flow toward the lateral extension, such as adjusting the upward air flow in the air duct downward first, then to the air outlet, and then forming an air flow along the lateral extension, or, directly adjusting the upward or downward air flow in the air duct to flow in a nearly horizontal direction first, and then flowing to the air outlet to directly flow along the lateral extension.

[0020] The longitudinal extension can further hinder liquid backflow into the deeper position of the air duct. Specifically, if liquid enters the air outlet along the lateral extension due to special circumstances, this part of liquid will also be hindered by the longitudinal extension and cannot continue to flow to the deeper position of the air duct, and will return to the carrying portion under the hindering effect of the longitudinal extension and the guiding effect of the lateral extension, so as to further reduce the waste of cleaning liquid.

[0021] In the prior art, the air flow blown by the fan below the cleaning tank reaches the upper part of the cleaning tank along the air duct, and then directly blows to the roller brush laterally or laterally upward. In the embodiment of the present application, the air flow is adjusted to flow downward to the air outlet by using the turning flow channel, which ensures the air flow speed and air flow rate blowing to the roller brush, and is beneficial to further improve the drying effect.

[0022] Optionally, the air duct comprises a bottom flow channel and a turning flow channel distributed along the air flow direction;

[0023] The bottom flow channel is located below the cleaning tank, the fan is located in the bottom flow channel, and the outlet of the bottom flow channel faces upward;

[0024] The turning flow channel is located above the bottom flow channel and is in communication with the bottom flow channel and the air outlet respectively, at least part of the inner wall of the turning flow channel is a curved surface wall protruding upward, and the curved surface wall can guide the fluid flowing out of the bottom flow channel to flow downward to the air outlet. It should be noted that upward or downward here is relative to the vertical direction.

[0025] The turning flow channel with a curved surface wall structure can reduce the resistance in the air flow turning process, ensure the air flow speed blowing to the roller brush, and is beneficial to further improve the drying effect.

[0026] Optionally, the base shell comprises:

[0027] The lower shell is provided with an air inlet in communication with the air inlet end of the fan;

[0028] The upper shell is mounted on the lower shell, the bottom flow channel is located between the upper shell and the lower shell, and the upper shell forms at least part of the tank bottom wall of the cleaning tank;

[0029] The flow guide wall of the air duct covers the outlet of the bottom flow channel and forms the air outlet between the upper shell.

[0030] When the cleaning piece needs to be dried, the fan is turned on, under the action of the fan, the air of the external environment forms an air flow which enters the air inlet end of the fan through the air inlet at the bottom of the lower shell, and then flows out of the fan from the air outlet end of the fan. The air flow flowing out of the air outlet end of the fan enters the turning flow channel under the guiding action of the bottom flow channel, and finally blows to the cleaning piece from the air outlet.

[0031] The air outlet is formed by the flow guide wall and the upper shell, and the upper shell and the lower shell are combined to form the base shell, which is simple in structure and convenient to assemble. The flow guide wall can be a separate part independent of the upper shell and the lower shell, and the flow guide wall is installed after the upper shell and the lower shell are assembled, so as to form a complete air duct and air outlet.

[0032] Optionally, the longitudinal section shape of the flow guide wall is inverted U-shaped; wherein the longitudinal section is parallel to the traveling direction of the cleaning device and perpendicular to the horizontal plane.

[0033] The longitudinal section shape of the flow guide wall is approximately inverted U-shaped. The originally upward airflow in the air duct can be adjusted to be downward by using the inverted U-shaped structure, thereby forming an airflow flowing along the transverse extension at the air outlet, and the structure is simple.

[0034] Optionally, one or more support partitions are arranged between the free end of the flow guide wall and the transverse extension, so that the air outlet is divided into multiple sub-air outlets, and the support partitions support the free end of the flow guide wall to ensure the stability of the opening size of the air outlet.

[0035] Optionally, the vertical distance between the free end of the flow guide wall and the transverse extension is 3-8 mm, the size of the opening of the air outlet is limited, so that the air outlet can output airflow with a large wind speed; the included angle between the extension dotted line of the free end of the flow guide wall and the extension dotted line of the transverse extension is 70-90°, so that the airflow of the air outlet can flow quickly along the transverse extension, and the airflow flowing in other directions is reduced. By limiting these sizes, the free end of the flow guide wall and the transverse extension can better cooperate to blow the airflow blown by the fan to the bottom of the cleaning piece from the gap between the squeegee and the bottom wall of the groove with a large wind speed and a large air volume, thereby improving the drying effect on the cleaning piece.

[0036] Optionally, the base shell further comprises an air inlet in communication with the air inlet end of the fan, and the air inlet is located at the bottom of the base shell and is arranged downward.

[0037] The base is supported on a support surface such as the ground or a table top by the bottom of the base shell. The air inlet arranged downward at the bottom of the base shell not only makes full use of the space of the base shell, but also makes the appearance of the base more simple and improves the use experience, and is also conducive to ensuring the air flow and air speed entering the air duct, thereby improving the drying effect.

[0038] Optionally, the number of air inlets is at least two, and the at least two air inlets are respectively located on both sides of the fan.

[0039] A larger number of air inlets is conducive to improving the air volume entering the air duct and improving the drying effect.

[0040] Optionally, the carrier portion is a transparent member, and the base further comprises:

[0041] An infrared emitter is located below the transparent member, and the infrared emitter is used to emit infrared rays, at least part of the infrared rays can penetrate the transparent member and radiate to the cleaning piece.

[0042] In the present scheme, the transparent member can be a light-transmitting glass, and the infrared emitter can be an infrared heating tube. The infrared light generated by the infrared heating tube has strong penetration. The infrared light passes through the light-transmitting glass above the infrared heating tube and then irradiates the cleaning member, i.e., the roller brush. A part of the infrared light penetrates the roller brush and irradiates into the interior of the brush. The infrared light generates radiation heat in the interior of the brush, and the radiation heat dries the roller brush from the inside to the outside.

[0043] When the infrared light penetrates the light-transmitting glass above the infrared heating tube, the light-transmitting glass absorbs a part of the infrared light and converts the infrared light into heat, so that the temperature of the glass rises. In the self-cleaning stage, the heat of the glass is transferred to the self-cleaning water in the water distributor and then injected into the base. The heated water can generate nearly 100℃ boiling water, so that the roller brush is deeply soaked, cleaned and high-temperature sterilized. In the drying stage, the heat of the glass is transferred to the bristles on the surface of the roller brush by heat conduction.

[0044] Because the drying principle of the infrared drying is different from the conventional drying method, the water on the bristles is easily evaporated by the infrared drying. However, if the humid hot air cannot be removed in time after the evaporation, the problems of false drying and re-humidification can occur. The problem of false drying refers to that the drying speed of the cleaning member is too fast, so that the water cannot be completely evaporated before the drying is stopped. Because of the residual heat, the cleaning member feels dry when it is touched, but it is actually not completely dried. The problem of re-humidification refers to that the drying speed of the cleaning member is too fast, so that the evaporated water vapor accumulates in the vicinity to form local humid air. After the drying is stopped, the temperature of the cleaning member gradually decreases. After the temperature decreases, the surface of the cleaning member is particularly easy to adsorb the local humid air and become slightly wet, so that the drying effect is poor. These problems are particularly prominent at the bottom of the cleaning member. Therefore, the present scheme further includes a fan and an air outlet and the like matched components, so that a large amount of air flow can be output to the bottom of the cleaning member to improve the efficiency of removing the humid hot air, and then the drying efficiency is further improved. The present scheme uses the three heat transfer modes of heat radiation, heat conduction and heat convection for all-around three-dimensional drying technology, so that the roller brush is dried from the inside to the outside.

[0045] The second aspect of the present application provides a base for a cleaning device. The base is used for cleaning and drying a cleaning member of the cleaning device. The base comprises:

[0046] a fan;

[0047] a base shell provided with a cleaning tank for placing the cleaning member; the base shell is provided with an air duct, and the base shell is further provided with an air outlet communicating with the air duct and the cleaning tank. The vertical distance between the free end of the flow guide wall of the air duct and the tank bottom wall of the cleaning tank is 3-8mm;

[0048] The fan is located in the air duct. The air flow blown by the fan is sequentially blown out through the air duct and the air outlet, and then blown along the tank bottom wall of the cleaning tank to the cleaning member.

[0049] Similar to the first aspect of the foregoing embodiment, the vertical distance between the free end of the guide wall and the bottom wall of the groove is 3-8 mm, indicating that the position of the air outlet is relatively low, and the airflow blown by the fan can be blown more to the cleaning piece, thereby improving the drying effect. Moreover, the airflow flowing out of the air outlet can be guided to the cleaning piece by the bottom wall of the groove, and the wind power is more concentrated on the cleaning piece, which is conducive to further improving the drying effect.

[0050] The third aspect of the present application provides a base for a cleaning device, the base being used for washing and drying a rolling brush of the cleaning device, the base comprising:

[0051] a fan;

[0052] a base housing, a top of the base housing being provided with a washing groove for placing the rolling brush; the base housing is provided with an air duct, and the base housing is further provided with an air outlet communicating with the air duct and the washing groove; the fan is located in the air duct, and the distance from the horizontal plane tangent to the bottom of the rolling brush to the top edge of the air outlet is less than the distance from the horizontal plane passing through the axis of the rolling brush to the top edge of the air outlet; the airflow blown by the fan is blown out through the air duct and the air outlet in turn, and then blown to the rolling brush along the bottom wall of the washing groove; the washing groove is provided with a transparent member for carrying the rolling brush, which is located below the rolling brush and can be in contact with the rolling brush;

[0053] an infrared emitter located below the transparent member, the infrared emitter being used for emitting infrared rays, at least part of the infrared rays being able to penetrate the transparent member and radiate to the rolling brush;

[0054] a heat dissipation member located below the infrared emitter and in the air duct;

[0055] The airflow blown by the fan at least passes through the heat dissipation member, so as to transport the heat of the heat dissipation member to the rolling brush.

[0056] The infrared light generated by the infrared emitter has strong penetration, and is irradiated to the rolling brush through the transparent member above the infrared emitter. A part of the infrared light penetrates the brush bristles and irradiates into the brush bristles, and the infrared light generates radiation heat in the brush bristles, thereby drying the rolling brush bristles from the inside to the outside.

[0057] The infrared light penetrates the transparent member above the infrared heating tube. The transparent member absorbs part of the infrared light and converts it into heat, causing the temperature of the transparent member to rise. In the self-cleaning stage, the heat of the transparent member is transferred to the cleaning liquid in the cleaning tank, heating the cleaning liquid. The high-temperature cleaning liquid (such as 100℃, or other temperature values between 60-100℃) deeply soaks the roller brush for cleaning and high-temperature sterilization. The transparent member can form part of the bottom wall of the cleaning tank, and the other part of the bottom wall is formed by the base shell. The transparent member can be in contact with the roller brush, and then in the drying stage, the heat of the transparent member can be transferred to the bristles on the surface of the roller brush through heat conduction.

[0058] The heat dissipation member can absorb infrared light to generate heat. The airflow blown by the fan passes through the heat dissipation member and is heated to form a hot airflow, which is blown to the roller brush through the air outlet. The high-temperature airflow dries the bristles through convection heat exchange, removes the water vapor evaporated on the bristles, and accelerates the drying speed. At the same time, the high-temperature airflow can also achieve the effect of full-link drying. In summary, the infrared emitter as a heat source optimizes the heat conduction mode in the prior art, realizes a full-dimensional drying technology including three heat conduction modes of heat radiation, heat conduction and heat convection, and performs full-dimensional drying on the roller brush from the inside to the outside, reducing or even avoiding the current problems of the roller brush such as not being dried, emitting odor, etc.

[0059] Optionally, the air duct includes at least two sub-air ducts distributed along the width direction of the base, and the at least two sub-air ducts can respectively guide the airflow to different positions of the roller brush in the axial direction; and the heat dissipation member is located in at least one of the sub-air ducts.

[0060] The air outlet can be a long and narrow air outlet formed along the width direction of the base (if the cleaning member is a roller brush, the direction also refers to the axial direction of the roller brush). The airflows from the sub-air ducts at different positions also pass through the air outlet at different positions to blow to the cleaning member.

[0061] For the sub-air ducts provided with the heat dissipation members, the airflow flowing out of the sub-air ducts can be heated by the heat dissipation members to form hot airflow; for the sub-air ducts without the heat dissipation members, the temperature of the airflow flowing out of the sub-air ducts is relatively low, which can be referred to as normal-temperature airflow. The heat dissipation members can be arranged in all the sub-air ducts, so that the airflow blown out of all the sub-air ducts is hot airflow. Alternatively, the heat dissipation members can be arranged in part of the sub-air ducts, and the heat dissipation members are not arranged in the other part of the sub-air ducts, for example, the heat dissipation members can be arranged in some sub-air ducts corresponding to the middle position of the roller brush, and the heat dissipation members are not arranged in the sub-air ducts corresponding to the two end positions of the roller brush; or the heat dissipation members are not arranged in some sub-air ducts corresponding to the middle position of the roller brush, and the heat dissipation members are arranged in the sub-air ducts corresponding to the two end positions of the roller brush. In this way, the airflow flowing out of the air outlet is a mixture of hot airflow and normal-temperature airflow, which is beneficial to stirring the flow field of the airflow, and the temperature of the drying airflow at different positions of the roller brush can be adjusted according to the drying requirements at the different positions, so as to facilitate fine and intelligent control of drying and improve the use experience.

[0062] Optionally, the base further comprises: a reflecting member, the reflecting member is located below the transparent member, the reflecting member and the transparent member jointly enclose a cavity, and the infrared emitter is located in the cavity; at least part of the infrared rays are reflected to the transparent member through the reflecting member and radiated to the roller brush through the transparent member, the bottom of the reflecting member has an opening communicating with the cavity, and the heat dissipation member is opposite to the opening.

[0063] The length of the heat dissipation member is greater than or equal to the length of the opening; and / or the width of the heat dissipation member is greater than or equal to the width of the opening.

[0064] The reflecting member can be a mirror surface reflecting shell arranged on both sides of the infrared emitter and semi-enclosing the infrared emitter, and the remaining direction infrared light emitted by the infrared emitter is reflected by the reflecting member and then emitted from the upper transparent member, thereby increasing the irradiation intensity of the infrared light below the roller brush and improving the energy efficiency.

[0065] The length of the heat dissipation member and the length of the opening both refer to the length parallel to the axial direction of the roller brush. The width of the heat dissipation member and the width of the opening both refer to the width parallel to the advancing direction of the cleaning device.

[0066] The length of the heat dissipation member being greater than or equal to the length of the opening can ensure the heat dissipation effect on the infrared emitter in the length direction; and the width of the heat dissipation member being greater than or equal to the width of the opening can ensure the heat dissipation effect on the infrared emitter in the width direction.

[0067] Optionally, the heat dissipation member comprises a heat dissipation substrate and a plurality of fins, and the plurality of fins are distributed along the axial direction of the infrared emitter, wherein the length direction of the infrared emitter is parallel to the axis of the roller brush.

[0068] The heat dissipation base can increase the heat dissipation area and also can be used as a mounting carrier of the fins. The more the fins are, the larger the heat dissipation area is, and the more the heat dissipation effect is improved.

[0069] The heat dissipation base can extend along the rolling brush axis, and the fins can be located in the corresponding sub-air ducts. The more the fins arranged in the sub-air ducts are, the higher the temperature of the air flow out of the sub-air ducts can be; on the contrary, the less the fins arranged in the sub-air ducts are, the lower the temperature of the air flow out of the sub-air ducts can be.

[0070] Optionally, the transparent member forms part of a bottom wall of the cleaning tank, the transparent member is an infrared light transparent glass member, and the light transmittance of the transparent member is 20%-40%.

[0071] The transparent member with a light transmittance of 20%-40% can ensure the transmission effect of infrared rays and also has a certain shielding effect on the internal structure of the base below the transparent member.

[0072] The fourth aspect embodiment of the present application provides a base for a cleaning device, which is used for cleaning and drying a cleaning member of the cleaning device, and has the following characteristics.

[0073] A fan;

[0074] A base shell is provided with a cleaning tank for placing the cleaning member; the base shell is provided with an air duct, and is also provided with an air outlet communicating with the air duct and the cleaning tank; the fan is located in the air duct, and the distance from the horizontal plane tangent to the bottom of the cleaning member to the top edge of the air outlet is less than the distance from the horizontal plane passing through the central axis of the cleaning member to the top edge of the air outlet; the air flow blown out by the fan passes through the air duct and the air outlet in sequence and then blows towards the cleaning member along the bottom wall of the cleaning tank; the cleaning tank is provided with a transparent member for carrying the cleaning member, which is located below the cleaning member and can contact the cleaning member;

[0075] An infrared emitter is located below the transparent member, and the infrared emitter is used for emitting infrared rays, at least part of which can penetrate the transparent member and radiate to the cleaning member;

[0076] A heat dissipation member is located below the infrared emitter and outside the air duct;

[0077] The air flow delivered to the cleaning member by the air outlet is a normal temperature air flow.

[0078] Different from the third aspect embodiment, the heat dissipation member can also be arranged outside the air duct, and thus the air flow blown out by the air duct can be a normal temperature air flow. The use of the normal temperature air flow can reduce the risk of scalding the rolling brush by excessively high temperature.

[0079] The fifth aspect embodiment of the present application provides a cleaning system, which comprises:

[0080] The base for the cleaning device according to any one of the preceding embodiments;

[0081] The cleaning device comprises a body assembly and a floor brush assembly; the body assembly is rotationally connected with the floor brush assembly, the top of the body assembly is provided with a handle, and the floor brush assembly is capable of moving on a surface to be cleaned.

[0082] The cleaning system comprises the base of the preceding embodiments, and thus has the beneficial effects of the base of the preceding embodiments, which will not be described herein.

[0083] Optionally, the floor brush assembly comprises a cleaning piece and a squeegee assembly; the cleaning piece is used for brushing the surface to be cleaned; the squeegee assembly is used for scraping dirt on the surface to be cleaned; the squeegee assembly comprises a squeegee and a driving part; the squeegee is arranged on the front side of the cleaning piece in the moving direction; and the driving part is configured to drive the squeegee to rise or fall; the squeegee rises in the retracted state, and the squeegee falls in the working state.

[0084] Under the driving action of the driving part, the squeegee can rise or fall. During the movement of the floor brush assembly in the moving direction (generally forward), the cleaning piece can brush the surface to be cleaned in the moving direction; during the forward pushing of the body assembly, the squeegee assembly is raised, so as to prevent the squeegee assembly from hindering the dirt on the ground in front from being sucked away; during the backward pulling of the body assembly, the squeegee is driven by the driving part to move towards the surface to be cleaned and to be attached to the surface to be cleaned, i.e., the squeegee assembly falls, and the squeegee can scrape the dirt on the surface to be cleaned, thereby facilitating the reduction of the water stains remaining on the surface to be cleaned and improving the cleaning effect.

[0085] Optionally, when the cleaning device is placed on the base, the distance between the squeegee and the bottom wall of the groove is 3-6 mm, and the distance between the squeegee and the air outlet is 0-6 mm.

[0086] Alternatively, the ratio of the distance between the squeegee and the bottom wall of the groove to the length of the air outlet in the vertical direction is 0.9-1.1, and the ratio of the distance between the squeegee and the bottom wall of the groove to the distance between the squeegee and the air outlet is 0.9-1.2.

[0087] By limiting the aforementioned related size parameters of the squeegee, the bottom wall of the groove and the air outlet, the airflow blown out of the air outlet can quickly enter the gap between the squeegee and the bottom wall of the groove, so as to reach the bottom of the cleaning piece, reduce the outflow of the airflow and ensure the drying effect.

[0088] When the cleaning device is placed on the base, the aforementioned scraping strip assembly is in a lifted state, so that a certain distance is formed between the scraping strip and the bottom wall of the groove. In combination with the limitation of the distance size, a sufficient distance can be formed between the scraping strip and the bottom wall of the groove, and the scraping strip does not block the air outlet, so that the drying air flow can smoothly blow to the cleaning piece, and the drying effect on the cleaning piece is ensured.

[0107] As Figure 1As shown, the cleaning system comprises a cleaning device 100 and a base 200. The cleaning device 100 can comprise a scrubbing assembly 104. In operation, the cleaning device 100 travels on a surface to be cleaned, and the cleaning element at the bottom of the scrubbing assembly 104 contacts and rubs against the surface to be cleaned to clean the surface.

[0108] The cleaning device can include, but is not limited to, a scrubber, an electric mop, etc.

[0109] Figure 4 The cleaning element is exemplarily shown as a roller brush 110. It can be understood that the cleaning element can also be a track or a double roller brush, etc. However, the application is not limited thereto. For the convenience of description, the cleaning system of the embodiments of the application is described below by taking the cleaning element as the roller brush 110 and the cleaning device as the scrubber.

[0110] The scrubbing assembly 104 can further comprise a scrubbing body and a walking wheel 102. The scrubbing body is a main support structure of the scrubbing assembly 104, and the roller brush 110 and the walking wheel 102 can be mounted on the scrubbing body. For example, the scrubbing body can have a receiving cavity, and the roller brush 110 can be located in the receiving cavity and can rotate around the axis of the roller brush 110 itself. When the cleaning device is in operation, the roller brush 110 contacts the surface to be cleaned, and the roller brush 110 is driven to rotate at a high speed by a roller brush motor mounted in the scrubbing body, so that the roller brush 110 can contact and rub against the surface to be cleaned to clean the surface. The walking wheel 102 contacts and rolls on the surface to be cleaned to assist the cleaning device to travel on the surface to be cleaned, and can improve the stability of the scrubbing assembly 104 on the surface to be cleaned.

[0111] As shown in FIG. 1, Figure 3 The base 200 is provided with a cleaning tank 202 for placing the roller brush 110. When the cleaning device 100 is parked on the base 200 after completing the cleaning operation, the cleaning device 100 can be self-cleaned, and the roller brush 110 is cleaned and dried in the cleaning tank 202 during the self-cleaning process.

[0112] As shown in FIG. 1, Figure 1 The cleaning device 100 further comprises a clean water tank 103 and a dirty water tank 101. The clean water tank 103 can provide cleaning liquid to the roller brush to wet the roller brush and realize wet cleaning. When the cleaning device 100 is placed on the base 200, the cleaning liquid provided by the clean water tank 103 can also be used for self-cleaning. The dirty water tank 101 is used to store the dirty water or solid dirt after cleaning.

[0113] Figure 2The structural diagram of the existing base is shown, and the existing base 10 includes an existing cleaning tank 11 and an existing air outlet 12. The existing air outlet 12 is located at the front side of the cleaning piece, and the front side of the cleaning piece of the existing cleaning device is not provided with a scraping strip assembly, but although the cover is installed above the cleaning piece, the cover can hinder the dirt from being thrown forward, but the cover covers a smaller area of the circumferential side of the cleaning piece, the size of the existing air outlet 12 can match the size of the circumferential side of the cleaning piece which is not covered by the cover, and then the size of the existing air outlet 12 is larger, and the airflow flowing out of the existing air outlet 12 can be directly blown to the cleaning piece. However, for the cleaning device 100 provided with the lifting type scraping strip assembly 120 (see Figure 4 ), even if the scraping strip assembly 120 is in the lifting position, the scraping strip assembly 120 covers a larger area of the front side of the cleaning piece, and the scraping strip 123 in the scraping strip assembly 120 is located lower, if the existing air outlet 12 is used for drying operation, only a small part of the airflow blown out of the existing air outlet 12 blows to the cleaning piece, the airflow is wasted more, and the drying effect is poorer.

[0114] In order to improve the drying effect of the cleaning piece in the self-cleaning process, the base 200 for the cleaning device 100 is provided, and the base 200 is used for cleaning and drying the cleaning piece of the cleaning device 100. The specific embodiments are described in detail below. Figures 1 to 9

[0115] Embodiment 1

[0116] The base 200 of embodiment 1 is used for cleaning and drying the cleaning piece of the cleaning device 100, and the base 200 includes a fan 210 and a base shell 220.

[0117] As shown in Figure 6 , the base shell 220 is provided with a cleaning tank 202 for placing the cleaning piece; the base shell 220 is provided with an air duct 230 Figure 4 , a guide wall 223 of the air duct 230 and a tank bottom wall of the cleaning tank 202 form an air outlet 201, and the air outlet 201 communicates the air duct 230 and the cleaning tank 202; as shown in Figure 3 and Figure 4 , the fan 210 is located in the air duct 230, and the airflow blown out of the fan 210 is blown out in sequence through the air duct 230 and the air outlet 201, and then blown to the cleaning piece along the tank bottom wall of the cleaning tank 202.

[0118] ​The air outlet 201 is formed by the bottom wall of the cleaning tank 202 and the flow guide wall 223, which reduces the position of the air outlet 201, so that the output airflow is not easily blocked by the shell of the brush assembly 104, and the airflow blown by the fan 210 can reach the cleaning member more.

[0119] In some optional embodiments, as shown in Figure 5 The cleaning member of the cleaning device 100 is a roller brush 110, as shown in Figure 6 The bottom wall of the tank includes a bearing part 2211 and a transversely extending part 2212. The bearing part 2211 is used to place the roller brush 110 and store the cleaning liquid. The transversely extending part 2212 extends from the bearing part 2211 to the air duct 230, and the height of the transversely extending part 2212 is higher than that of the bearing part 2211, so that the liquid on the transversely extending part 2212 flows to the bearing part 2211 under the action of gravity. The transversely extending part 2212 and the flow guide wall 223 of the air duct 230 form the air outlet 201.

[0120] Before drying, the cleaning member needs to be cleaned with cleaning liquid. During the cleaning process, the water distributor of the cleaning device 100 sprays cleaning liquid, which preferentially collects in the lower bearing part 2211 and is not easily directed to the higher transversely extending part 2212. This can effectively prevent the cleaning liquid or the sewage after cleaning from flowing back into the air outlet 201 or the air duct 230 through the transversely extending part 2212, thereby reducing the impact of the cleaning liquid or the sewage on the air duct 230 or the fan 210.

[0121] In addition, in the prior art, the distance between the existing air outlet 12 and the front side of the brush assembly is small. If a scraper assembly 120 is installed on the front side of the cleaning member, the thickness of the front side of the cleaning member will increase, and the cleaning device placed on the existing base will also easily cause insufficient space on the front side of the cleaning member, and the scraper assembly 120 has the risk of being damaged. Even the scraper assembly 120 can block the existing air outlet 12, further reducing the drying effect. In the embodiments of the present application, the transversely extending part 2212 can increase the distance between the air outlet 201 and the front side of the brush assembly 104, which can reduce the risk of damage to the scraper assembly 120 and the risk of blocking the air outlet 201, and ensure the drying effect.

[0122] Without limitation, the cleaning liquid can be water or a mixture of water and cleaning agent.

[0123] In some optional embodiments, as shown in Figure 6As shown, the degree of downward concavity of the lateral extension 2212 is less than the degree of downward concavity of the bearing portion 2211.

[0124] Compared to the support portion 2211, the lateral extension 2212 is positioned higher, creating a height difference between them. Furthermore, the lateral extension 2212 has a less pronounced downward curve, indicating a gentler slope that facilitates airflow guidance to the cleaning component and reduces the accumulation of cleaning liquid. In contrast, the more curved support portion 2211 is more prone to liquid accumulation. Thus, even if some liquid flows forward towards the lateral extension 2212, it will be guided to the support portion 2211, further reducing the risk of liquid backflow into the air outlet 201 or the duct 230.

[0125] In some embodiments, the lateral extension 2212 includes an inclined top surface that slopes from low to high in the direction from the support portion 2211 toward the air outlet 201, which can better prevent liquid backflow and better guide the liquid to the support portion 2211.

[0126] In some alternative embodiments, the depth of the bottom wall of the tank in the vertical direction ( Figure 6 The distance between the tangent line at the lowest point of the cleaning tank 202 and the horizontal plane parallel to the top of the cleaning tank 202 is less than 1 / 3, 1 / 5, 1 / 8, 1 / 10 or 1 / 11 of the radius of the roller brush 110.

[0127] The cleaning tank 202 is shallow and has a gentle slope at the bottom. This structure can reduce the resistance when the fluid passes through and is more conducive to guiding the airflow out of the air outlet 201.

[0128] Figure 6 In the embodiment shown, the vertical depth H of the cleaning tank 202 is approximately 3 mm, the radius of the roller brush 110 is approximately 30 mm, and the vertical depth H of the bottom wall of the tank is approximately 1 / 10 of the radius of the roller brush 110.

[0129] In some optional embodiments, the cleaning tank 202 further comprises a longitudinal extension 2213 located in the air duct 230, and the guide wall 223 is arranged on the longitudinal extension 2213 with a gap, the longitudinal extension 2213 extends upward from the position of the transverse extension 2212, and the longitudinal extension 2213 and the guide wall 223 form a diversion flow channel 232, which is configured to adjust the air flow in the air duct 230 to flow towards the transverse extension 2212, such as adjusting the upward air flow in the air duct 230 to flow downward first, and then to the air outlet 201 to form an air flow along the transverse extension 2212, or directly adjusting the upward or downward air flow in the air duct 230 to flow horizontally first, and then to the air outlet 201 to flow along the transverse extension 2212 directly.

[0130] The longitudinal extension 2213 can further hinder the liquid from flowing back into the air duct 230 deeper. Specifically, if the liquid enters the air outlet 201 along the transverse extension 2212 due to special circumstances, the liquid will also be hindered by the longitudinal extension 2213 and cannot continue to flow deeper into the air duct 230, and will return to the bearing part 2211 under the hindering effect of the longitudinal extension 2213 and the guiding effect of the transverse extension 2212, which is also conducive to reducing the waste of cleaning liquid.

[0131] In the prior art, the air flow blown by the fan below the cleaning tank reaches the upper part of the cleaning tank along the air duct, and then flows directly to the side or upward to the roller brush. In the embodiments of the present application, the diversion flow channel 232 can adjust the air flow to flow downward to the air outlet 201, which ensures the air flow speed and air flow rate blowing to the roller brush 110, and is conducive to further improving the drying effect.

[0132] In some optional embodiments, as shown in Figure 5 The air duct 230 comprises a bottom flow channel 231 and a diversion flow channel 232 distributed along the air flow direction; the bottom flow channel 231 is located below the cleaning tank 202, the fan 210 is located in the bottom flow channel 231, and the outlet of the bottom flow channel 231 faces upward; the diversion flow channel 232 is located above the bottom flow channel 231 and is in communication with the bottom flow channel 231 and the air outlet 201 respectively, and at least part of the inner wall of the diversion flow channel 232 is a curved upward inner wall, which can guide the fluid flowing out of the bottom flow channel 231 to flow downward to the air outlet 201. It should be noted that the upward or downward here is relative to the vertical direction.

[0133] The diversion flow channel 232 with a curved inner wall structure can reduce the resistance in the air flow diversion process, ensure the air flow speed blowing to the roller brush 110, and be conducive to further improving the drying effect.

[0134] In some optional embodiments, as shown in Figure 5As shown, the base 200 further comprises a sealing sleeve 240 sleeved outside the junction of the diversion wall 223 and the bottom flow channel 231 and the diversion flow channel 232, and the sealing sleeve 240 is used to form an air seal to prevent air flow from leaking through the junction of the bottom flow channel 231 and the diversion flow channel 232.

[0135] In some optional embodiments, as shown in Figure 4 As shown, the base shell 220 comprises an upper shell 221, a lower shell 222, and a diversion wall 223, the lower shell 222 is provided with an air inlet 203 in communication with the air inlet end of the fan 210, the upper shell 221 is mounted on the lower shell 222, the bottom flow channel 231 is located between the upper shell 221 and the lower shell 222, and the upper shell 221 forms at least part of the tank bottom wall of the cleaning tank 202; the diversion wall 223 of the air duct 230 covers the outlet of the bottom flow channel 231 and forms an air outlet 201 between the diversion wall 223 and the upper shell 221.

[0136] When the drying and cleaning piece is needed, the fan 210 is turned on, under the action of the fan 210, the air in the external environment forms an air flow that enters the air inlet end of the fan 210 through the air inlet 203 at the bottom of the lower shell 222, and then flows out of the fan 210 from the air outlet end of the fan 210. The air flow flowing out of the air outlet end of the fan 210 enters the diversion flow channel 232 under the guidance of the bottom flow channel 231, and finally blows towards the cleaning piece through the air outlet 201.

[0137] The air outlet 201 is defined by the diversion wall 223 and the upper shell 221, and the upper shell 221 and the lower shell 222 are combined to form the base shell 220, which is simple in structure and easy to assemble. The diversion wall 223 can be a separate component independent of the upper shell 221 and the lower shell 222, and the diversion wall 223 is installed after the upper shell 221 and the lower shell 222 are assembled, thereby forming the complete air duct 230 and the air outlet 201.

[0138] In some optional embodiments, as shown in Figure 6 As shown, the longitudinal cross-sectional shape of the diversion wall 223 is inverted U-shaped; wherein the longitudinal cross-section is parallel to the running direction of the cleaning equipment 100 and perpendicular to the horizontal plane.

[0139] The longitudinal cross-sectional shape of the diversion wall 223 is approximately inverted U-shaped. The inverted U-shaped structure can adjust the air flow direction in the air duct 230 to flow downward, which is simple in structure.

[0140] Optionally, one or more support partitions are provided between the free end of the diversion wall and the transversely extending portion 2212, so that the air outlet is divided into a plurality of sub-air outlets, and the support partitions support the free end of the diversion wall to ensure the stability of the size of the air outlet opening.

[0141] Optionally, the vertical distance between the free end of the flow guide wall and the lateral extension 2212 is 3-8 mm, by limiting the size of the opening of the air outlet 201, so that the air outlet 201 can output air flow reaching a larger wind speed; the angle between the extension dotted line of the free end of the flow guide wall and the extension dotted line of the lateral extension 2212 is 70-90°, so that the air flow of the air outlet 201 can flow quickly along the lateral extension 2212, and the air flow flowing in other directions is reduced. By limiting these sizes, the free end of the flow guide wall and the lateral extension 2212 can better cooperate to blow the air flow blown by the fan 210 to the bottom of the cleaning piece at a larger wind speed and a larger air volume from the gap between the squeegee 123 and the groove bottom wall, thereby improving the drying effect on the cleaning piece.

[0142] In some optional embodiments, as shown in Figure 9 The base housing 220 further includes an air inlet 203 in communication with the air inlet end of the fan 210, and the air inlet 203 is arranged downward at the bottom of the base housing 220.

[0143] The base 200 is supported on the supporting surface such as the ground or table top by the bottom of the base housing 220. The air inlet 203 arranged downward at the bottom of the base housing 220 not only makes full use of the space of the base housing 220, but also makes the appearance of the base 200 more simple and improves the use experience, and is also conducive to ensuring the air inlet flow and air inlet speed in the air duct 230, thereby improving the drying effect.

[0144] In some optional embodiments, the number of air inlets 203 is at least two, and the at least two air inlets 203 are respectively located on both sides of the fan 210.

[0145] In the embodiment shown in FIG. 9, the air inlets 203 are two, and the two air inlets 203 are respectively arranged on both sides of the fan 210.

[0146] The larger number of air inlets 203 is conducive to improving the air inlet amount into the air duct 230, and is also conducive to improving the drying effect.

[0147] In some optional embodiments, as shown in Figure 5 and Figure 6 The carrier portion is a transparent member 260, and the base further includes an infrared emitter 250, which is located below the transparent member 260, and the infrared emitter 250 is used to emit infrared rays, and at least part of the infrared rays can penetrate the transparent member 260 and radiate to the cleaning piece.

[0148] In the present scheme, the transparent member 260 can be a light-transmitting glass, and the infrared emitter 250 can be an infrared heating tube. The infrared light generated by the infrared heating tube has strong penetration, and can penetrate through the light-transmitting glass above the infrared heating tube and then irradiate onto the cleaning member. A part of the infrared light penetrates through the brush bristles and irradiates into the interior of the brush bristles. The infrared light generates radiation heat in the interior of the brush bristles, and the radiation heat dries the brush bristles from the inside to the outside.

[0149] When the infrared light penetrates through the light-transmitting glass above the infrared heating tube, the light-transmitting glass absorbs a part of the infrared light and converts the infrared light into heat, so that the temperature of the glass rises. In the self-cleaning stage, the heat of the glass is transferred to the self-cleaning water injected into the base, so that the water is heated to generate boiling water at a temperature close to 100℃, and the brush is deeply soaked and cleaned and high-temperature sterilized. After the drying stage is entered, the heat of the glass dries the brush bristles on the surface of the brush by heat conduction.

[0150] Because the drying principle of the infrared drying is different from the conventional drying mode, the infrared drying makes the water on the wool extremely easy to evaporate. However, if the humid hot air cannot be removed in time after the evaporation, the problems of false drying and re-moistening will occur. The problem of false drying refers to that the drying speed of the cleaning member is too fast, so that the water has not been completely evaporated before the drying is stopped. Because of the residual heat, the cleaning member feels dry when touched, but in fact, the cleaning member is not completely dried. The problem of re-moistening refers to that the drying speed of the cleaning member is too fast, so that the evaporated water vapor accumulates in the vicinity to form local humid air. After the drying is stopped, the cleaning member gradually cools down. The surface of the cleaning member is particularly easy to adsorb the local humid air and become slightly wet, so that the drying effect is poor. These problems are particularly prominent at the bottom position of the cleaning member. Therefore, the present scheme further increases the fan 210 and the air outlet 201 and other matched components, so that a large amount of airflow can be output to the bottom of the cleaning member to improve the efficiency of removing the humid hot air, and then further improve the drying efficiency. The present scheme uses the three heat conduction modes of heat radiation, heat conduction and heat convection for omnidirectional three-dimensional drying technology, and performs omnidirectional drying on the brush from the inside to the outside.

[0151] Embodiment 2

[0152] The base 200 of the embodiment 2 also includes the fan 210 and the base shell 220. The base shell 220 is provided with a cleaning tank 202 for placing the cleaning member. The base shell 220 is provided with an air duct 230, and the base shell 220 is further provided with an air outlet 201 communicating with the air duct 230 and the cleaning tank 202. As shown in Figure 6 the vertical distance L between the free end of the flow guide wall of the air duct 230 and the tank bottom wall of the cleaning tank 202 is 3-8 mm. The fan 210 is located in the air duct 230. The airflow blown out by the fan 210 is sequentially blown out through the air duct 230 and the air outlet 201, and then blows along the tank bottom wall of the cleaning tank 202 to the cleaning member.

[0153] Figure 6 In the embodiment shown, the vertical distance L between the free end of the guide wall and the bottom wall of the cleaning tank 202 (also) Figure 5 The height referred to in h5 (which will be mentioned below) is approximately 5.5mm. It is understandable that the vertical distance L between the free end of the guide wall and the bottom wall of the cleaning tank 202 can also be 3mm, 4mm, 5mm, 6mm, 7mm or 8mm.

[0154] Similar to the first aspect of the embodiment described above, the vertical distance between the free end of the guide wall and the bottom wall of the tank can be 3-8 mm, indicating that the position of the air outlet 201 is relatively low, and the airflow blown by the fan 210 can blow more towards the cleaning parts, thus improving the drying effect. Moreover, the airflow flowing out of the air outlet 201 can be guided to the cleaning parts by the bottom wall of the tank, resulting in stronger and more concentrated airflow on the cleaning parts, which is conducive to further improving the drying effect.

[0155] The other structures of the base 200 in Embodiment 2 are the same as those in Embodiment 1, and will not be described again.

[0156] Example 3

[0157] like Figure 4 As shown, the base 200 of Embodiment 3 includes a fan 210, a base housing 220, an infrared emitter 250, and a heat sink 270. The base housing 220 has a cleaning tank 202 for placing the roller brush 110; the base housing 220 has an air duct 230 and an air outlet 201 connecting the air duct 230 and the cleaning tank 202. The fan 210 is located within the air duct 230, extending from the horizontal plane S1 tangent to the bottom of the roller brush 110 to the top edge of the air outlet 201. Figure 5 The distance h1 between the height positions corresponding to S2 and S2 is less than the distance h2 between the horizontal plane S3 along the axis of the roller brush 110 and the top edge of the air outlet 201. The airflow blown out by the fan 210 passes through the air duct 230 and the air outlet 201 in sequence and then blows along the bottom wall of the cleaning tank 202 toward the roller brush 110. The transmitting element 260 is located below the roller brush 110 and can contact the roller brush 110. The infrared emitter 250 is located below the transmitting element 260 and is used to emit infrared rays. At least part of the infrared rays can penetrate the transmitting element 260 and radiate to the roller brush 110. The heat sink 270 is located below the infrared emitter 250 and is located in the air duct 230. The airflow blown out by the fan 210 passes through the heat sink 270 at least to transfer the heat of the heat sink 270 to the roller brush 110. The infrared light generated by the infrared emitter 250 has strong penetrating power. It shines on the roller brush 110 through the transducer 260 above the infrared emitter 250. Some of the infrared light penetrates the brush bristles of the roller brush 110 and shines into the bristles. The infrared light generates radiant heat inside the bristles, drying the brush bristles of the roller brush 110 from the inside out.

[0158] When infrared light penetrates the transducer 260 above the infrared heating tube, the transducer 260 absorbs a portion of the infrared light, converting it into heat and raising its temperature. During the self-cleaning stage, the heat from the transducer 260 is transferred to the cleaning liquid in the cleaning tank 202, heating the liquid. The higher temperature of the cleaning liquid (e.g., 100℃, or other temperatures between 60-100℃) deeply immerses and cleans the roller brush 110, and also sterilizes it at high temperatures. The transducer 260 can form part of the bottom wall of the cleaning tank 202, while the other part of the bottom wall is formed by the base housing 220. The transducer 260 can contact the roller brush 110, and then, during the drying stage, the heat from the transducer 260 can iron and dry the bristles on the surface of the roller brush 110 through heat conduction.

[0159] The heat sink 270 can be made of materials with high thermal conductivity, such as aluminum or copper, and the surface can be blackened to further increase the absorption of infrared light and the heat conversion capacity.

[0160] The fan 210 in this embodiment can be an axial flow fan.

[0161] The heat sink 270 absorbs infrared light to generate heat. Airflow from the fan 210 is heated by the heat sink 270, forming a hot airflow. This hot airflow is then blown onto the roller brush 110 through the outlet 201. The high-temperature airflow dries the brush bristles through convection heat transfer, carrying away evaporated water vapor and accelerating the drying process. Simultaneously, the high-temperature airflow achieves a complete drying effect. In summary, the infrared emitter 250, acting as a heat source, optimizes the heat conduction methods in existing technologies, achieving a comprehensive three-dimensional drying technology that includes thermal radiation, thermal conduction, and thermal convection. This allows for all-around drying of the roller brush 110 from the inside out, reducing or even eliminating problems such as incomplete drying and unpleasant odors currently found in the roller brush 110.

[0162] For example, the temperature of the hot air flowing out of the air outlet 201 can reach above 50°C.

[0163] In some alternative embodiments, such as Figure 9 As shown, the air duct 230 includes at least two sub-air ducts 2221 distributed along the width direction of the base 200. The at least two sub-air ducts 2221 can respectively guide the airflow to different positions along the axial direction of the roller brush 110; the heat sink 270 is located in at least one sub-air duct 2221.

[0164] The air outlet 201 can be a narrow air outlet formed along the width direction of the base 200 (if the cleaning component is a roller brush 110, this direction also refers to the axial direction of the roller brush 110). The airflow from the sub-air ducts 2221 at different positions also passes through the air outlet 201 and blows towards the cleaning component at different positions.

[0165] For the sub-air duct 2221 provided with the heat dissipation piece 270, the airflow flowing out of the sub-air duct 2221 can be heated by the heat dissipation piece 270 to form a hot airflow; for the sub-air duct 2221 without the heat dissipation piece 270, the airflow flowing out of the sub-air duct 2221 is at a normal temperature and can be called a normal-temperature airflow. The heat dissipation piece 270 can be arranged in all the sub-air ducts 2221, so that the airflow blown out of all the sub-air ducts 2221 is a hot airflow. The heat dissipation piece 270 can also be arranged in part of the sub-air ducts 2221 and not arranged in another part of the sub-air ducts 2221, for example, the heat dissipation piece 270 can be arranged in some sub-air ducts 2221 corresponding to the middle position of the roller brush 110, and the heat dissipation piece 270 is not arranged in the sub-air ducts 2221 corresponding to the two end positions of the roller brush 110; or, the heat dissipation piece 270 is not arranged in some sub-air ducts 2221 corresponding to the middle position of the roller brush 110, and the heat dissipation piece 270 is arranged in the sub-air ducts 2221 corresponding to the two end positions of the roller brush 110. In this way, the airflow flowing out of the air outlet 201 is a mixture of hot airflows and normal-temperature airflows, which is beneficial to stirring the flow field of the airflows, and the temperature of the drying airflows at different positions of the roller brush 110 can be adjusted according to the drying requirements at the different positions, so as to facilitate fine and intelligent control of drying and improve the use experience.

[0166] The number of the sub-air ducts 2221 can be two, three, four or more. Figure 9 Five sub-air ducts 2221 are exemplarily shown.

[0167] In some optional embodiments, as shown in Figure 8 The base 200 further includes: a reflecting piece 280, the reflecting piece 280 is located below the penetrating piece 260, the reflecting piece 280 and the penetrating piece 260 jointly enclose a cavity 282, and the infrared emitter 250 is located in the cavity 282; at least part of the infrared rays are reflected to the penetrating piece 260 through the reflecting piece 280 and radiated to the roller brush 110 through the penetrating piece 260, the reflecting piece 280 has an opening 281 at the bottom and the opening 281 is communicated with the cavity 282, and the heat dissipation piece 270 is opposite to the opening 281; the length of the heat dissipation piece 270 is greater than or equal to the length of the opening 281; and / or, the width of the heat dissipation piece 270 is greater than or equal to the width of the opening 281.

[0168] The reflecting piece 280 can be a mirror surface reflecting shell arranged on both sides of the infrared emitter 250 and semi-enclosing the infrared emitter 250, the remaining directions of the infrared light emitted by the infrared emitter 250 are reflected by the reflecting piece 280 and then emitted from the upper penetrating piece 260, so as to increase the irradiation intensity of the infrared light below the roller brush 110 and improve the energy efficiency.

[0169] The length of the heat dissipation member 270 and the length of the opening 281 both refer to the length parallel to the axial direction of the roller brush 110. The width of the heat dissipation member 270 and the width of the opening 281 both refer to the width parallel to the direction of travel of the cleaning device 100.

[0170] The length of the heat dissipation member 270 being greater than or equal to the length of the opening 281 can ensure the heat dissipation effect on the infrared emitter 250 in the length direction; the width of the heat dissipation member 270 being greater than or equal to the width of the opening 281 can ensure the heat dissipation effect on the infrared emitter 250 in the width direction.

[0171] Exemplarily, the cross section of the reflecting member 280 can be designed as an ellipse, the infrared emitter 250 can be an infrared heating tube, the infrared heating tube is at one of the foci of the ellipse, and the center point of the roller brush 110 is at the other focus. By using the light rays emitted from one focus of the ellipse, the infrared light is emitted after passing through the wall surface of the ellipse and must pass through the other focus, thereby achieving full utilization of the infrared light.

[0172] In some optional embodiments, as shown in Figure 8 The heat dissipation member 270 includes a heat dissipation substrate 271 and a plurality of fins 272, and the plurality of fins 272 are distributed along the axial direction of the infrared emitter 250, wherein the length direction of the infrared emitter 250 is parallel to the axis of the roller brush 110.

[0173] The heat dissipation substrate 271 can increase the heat dissipation area and also serve as a mounting carrier for the fins 272. The more the number of fins 272, the larger the heat dissipation area, and the more conducive to improving the heat dissipation effect.

[0174] The heat dissipation substrate 271 can extend along the axial direction of the roller brush 110, and the fins 272 can be located in the corresponding sub-air duct 2221. The more the number of fins 272 arranged in the sub-air duct 2221, the higher the temperature of the airflow flowing out of the sub-air duct 2221; conversely, the fewer the number of fins 272 arranged in the sub-air duct 2221, the lower the temperature of the airflow flowing out of the sub-air duct 2221.

[0175] In some optional embodiments, the transparent member forms part of the tank bottom wall of the cleaning tank 202, the transparent member 260 is a glass member that is transparent to infrared light, and the light transmittance of the transparent member 260 is 20%-40%.

[0176] The transparent member 260 with a light transmittance of 20%-40% can not only ensure the transmission effect of infrared light, but also have a certain shielding effect on the internal structure of the base 200 below the transparent member 260.

[0177] In some embodiments, the transparent member 260 is made of black glass, and the light transmittance is about 30%.

[0178] The other structures of the base 200 in Embodiment 3 are the same as those in Embodiment 2, and will not be described again.

[0179] Example 4

[0180] The difference between Example 4 and Example 3 is that the heat sink 270 is located outside the air duct 230; the airflow delivered to the cleaning component by the air outlet 201 is at room temperature. Using room temperature airflow can reduce the risk of the roller brush 110 being damaged by excessively high temperatures.

[0181] The other structures of the base 200 in Embodiment 4 are the same as those in Embodiment 3, and will not be described again.

[0182] Example 5

[0183] Based on the foregoing, Embodiment 5 provides a cleaning system, which includes: a base 200 for cleaning device 100 and cleaning device 100 as described in any of the foregoing embodiments.

[0184] The cleaning device 100 includes a body assembly and a floor brush assembly 104; the body assembly and the floor brush assembly 104 are rotatably connected, the top of the body assembly is provided with a handle, and the floor brush assembly 104 can move on the surface to be cleaned.

[0185] The aforementioned clean water tank 103 and wastewater tank 101 can be installed on the body assembly.

[0186] The cleaning system includes the base 200 of the aforementioned embodiment, and therefore also has the beneficial effects of the base 200 of the aforementioned embodiment, which will not be described again here.

[0187] In some alternative embodiments, such as Figure 4 As shown, the floor brush assembly 104 includes a cleaning component and a scraper assembly 120. The cleaning component is used to clean the surface to be cleaned, and the scraper assembly 120 is used to scrape off dirt from the surface to be cleaned. The scraper assembly 120 includes a scraper 123 and a drive unit 121. The scraper 123 is located at the front of the cleaning component in the direction of travel. The drive unit 121 is configured to drive the scraper 123 to rise or fall. When the scraper 123 rises, it is in a retracted state, and when the scraper 123 falls, it is in an active state.

[0188] Driven by the drive unit 121, the scraper 123 can rise or fall. As the floor brush assembly 104 moves along the direction of travel (generally forward), the cleaning component can clean the surface to be cleaned along that direction. When the body assembly is pushed forward, the scraper assembly 120 rises to prevent it from obstructing the removal of dirt from the ground. When the body assembly is pulled back, the drive unit 121 drives the scraper 123 towards and against the surface to be cleaned, i.e., the scraper assembly 120 descends. The scraper 123 can then scrape away dirt from the surface to be cleaned, thereby reducing residual water stains and improving cleaning effectiveness.

[0189] The driving part 121 comprises a driving member, which can be a motor, and a transmission member, which can be a cam structure or a rod structure, etc. The scraping strip assembly 120 can further comprise a base 122, which is connected to the transmission member and the scraping strip 123 respectively. Under the driving of the driving member, the transmission member drives the scraping strip 123 to rise or fall through the base 122.

[0190] In some optional embodiments, when the cleaning device 100 is placed on the base 200, the distance h3 between the scraping strip 123 and the groove bottom wall is 3-6 mm, and the distance h4 between the scraping strip 123 and the air outlet 201 is 0-6 mm.

[0191] In some optional embodiments, referring to Figure 5 and Figure 10 , the ratio of the distance h3 between the scraping strip 123 and the groove bottom wall to the vertical length h5 of the air outlet 201 is 0.9-1.1, and the ratio of the distance h3 between the scraping strip 123 and the groove bottom wall to the distance h4 between the scraping strip 123 and the air outlet 201 is 0.9-1.2.

[0192] By limiting the aforementioned related size parameters of the scraping strip 123, the groove bottom wall and the air outlet 201, the airflow blown out of the air outlet 201 can quickly enter the gap between the scraping strip 123 and the groove bottom wall, so as to reach the bottom of the cleaning piece, reduce airflow escape, and ensure the drying effect.

[0193] For example: Figure 5 In the embodiment shown, when the cleaning device 100 is placed on the base 200, the distance h3 between the scraping strip 123 and the groove bottom wall is about 4.5 mm, and the distance h4 between the scraping strip 123 and the air outlet 201 is about 4 mm.

[0194] When the cleaning device 100 is placed on the base 200, the aforementioned scraping strip assembly 120 is in the raised state, so that a certain distance is formed between the scraping strip 123 and the groove bottom wall. In combination with the limitation of the distance size, a sufficient distance can be formed between the scraping strip 123 and the groove bottom wall, and the scraping strip 123 will not block the air outlet 201, so as to ensure that the drying airflow is smoothly blown to the cleaning piece and ensure the drying effect on the cleaning piece.

[0195] The embodiments or implementations in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts between the embodiments can be mutually referred to.

[0196] In the description of the specification, the description of "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are contained in at least one embodiment or example of the present application.
