Description

Technical Field

[0001] The present invention relates to the technical field of smart home appliances, and in particular to a cleaning device and a base thereof. Background Art

[0002] With the advancement of technology and the development of society, cleaning equipment for indoor floor cleaning (such as floor scrubbers and vacuum cleaners) has gradually entered people's lives. Traditional cleaning equipment generally consists of a body and a base. When the cleaning equipment is in the cleaning mode, the body and base are separated, and the body moves over the surface to be cleaned, allowing the roller brush on the body to clean the surface. When the cleaning equipment is in the drying mode, the body and base are connected, and the roller brush is attached to the outside of the base. Air flows through the drying channel of the base and blows towards the roller brush to dry it.

[0003] During the drying process, the roller brush rotates relative to the base, allowing the airflow to fully contact the outer surface of the roller brush, thus quickly drying the roller brush. However, precisely because the roller brush rotates, the centrifugal force can easily cause dirty water on the roller brush to be thrown into the drying channel, posing a significant safety hazard. Summary of the Invention

[0004] Based on this, it is necessary to provide a cleaning device and a base thereof with smaller safety hazards in order to address the problem of greater safety hazards.

[0005] A base, used for performing a first drying operation on a roller brush when the moisture content of the roller brush is greater than a set threshold, the base comprising:

[0006] a seat body, in which an air outlet passage is formed; and

[0007] A blocking component is connected to the base and includes a water-blocking and breathable member;

[0008] When the first drying operation is performed, the air outlet channel itself is constructed to form a drying channel with the air outlet facing the roller brush, and the water-blocking and air-permeable member at least partially closes the air outlet.

[0009] In one embodiment, the base is further configured to perform a second drying operation on the roller brush when the water content of the roller brush is less than or equal to the set threshold;

[0010] When the second drying operation is performed, the air outlet channel itself is also constructed to form a drying channel with the air outlet facing the roller brush, and the water-blocking and air-permeable component at least opens a portion of the air outlet.

[0011] In one embodiment, when the first drying operation is performed, the water-blocking and breathable member completely closes the air outlet; when the second drying operation is performed, the water-blocking and breathable member completely opens the air outlet.

[0012] In one embodiment, the blocking assembly further includes a rotating shaft, and the water-blocking and breathable member is a flexible member with one end wound around the rotating shaft;

[0013] When the first drying operation is performed, the rotating shaft is controlled to rotate in a first direction and wind up the water-blocking and breathable member, and the rotating shaft is controlled to move in the direction of gravity until the water-blocking and breathable member completely closes the air outlet;

[0014] When performing the second drying operation, the rotating shaft is controlled to rotate in a second direction opposite to the first direction and release the water-blocking and breathable member, and the rotating shaft is controlled to move downward along the gravity direction until the water-blocking and breathable member fully opens the air outlet.

[0015] In one embodiment, the blocking assembly further includes a driving member, a gear, and a rack, wherein the driving member is in transmission connection with the rotating shaft, the gear is sleeved on and fixed to the rotating shaft, and the rack extends along the direction of gravity and meshes with the gear.

[0016] The rotating shaft rotates under the action of the driving member and moves up and down under the action of the gear.

[0017] In one embodiment, the blocking assembly further includes a guide member, which is coupled to the base and configured to guide the rotating shaft to move up and down.

[0018] In one embodiment, a guide channel extending along the direction of gravity is formed on the guide member, and the rotating shaft passes through the guide channel.

[0019] In one embodiment, the water-blocking and breathable member is a water-absorbing component.

[0020] In one embodiment, the blocking component is located in the air outlet channel.

[0021] A cleaning device comprises a base as described in any one of the above embodiments.

[0022] In the aforementioned cleaning device and its base, when the base performs the first drying operation, the air outlet passage itself is configured to form a drying passage with the air outlet directed toward the roller brush, and the water-blocking and breathable member at least partially closes the air outlet. The water-blocking and breathable member provides ventilation, allowing airflow to pass through the member and toward the roller brush to dry it. Furthermore, the water-blocking and breathable member also provides a water-blocking function. Because the water-blocking and breathable member closes at least partially the air outlet, the water-blocking and breathable member effectively reduces the amount of sewage flowing into the air outlet passage, thereby mitigating safety hazards associated with the cleaning device and its base.

[0030] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0035] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0036] Please also refer to Figure 1 and Figure 2 The present application provides a cleaning device 1, which may include a floor scrubber, a vacuum cleaner, and other cleaning devices capable of cleaning a surface to be cleaned.

[0037] The cleaning device 1 comprises a base 100 and a body. The body comprises a main body 220 and a roller brush 210 mounted on the main body 220. When the cleaning device 1 is in the cleaning mode, the body is separated from the base 100 and moves over the surface to be cleaned, allowing the roller brush 210 attached to the main body 220 to perform a cleaning operation on the surface to be cleaned. When the cleaning device 1 is in the drying mode, the body is connected to the base 100, the roller brush 210 is attached to the outside of the base 100, and the base 100 performs a drying operation on the roller brush 210.

[0038] Specifically, the drying operation includes a first drying operation and a second drying operation. When the water content of the roller brush 210 is greater than the set threshold, the base 100 performs the first drying operation on the roller brush 210. When the water content of the roller brush 210 is less than or equal to the set threshold, the base 100 performs the second drying operation on the roller brush 210.

[0039] It can be understood that the moisture content of the roller brush 210 can be measured by a moisture sensor, a weight sensor or other structures. The specific measurement form is not limited. It only needs to ensure that the cleaning device 1 can obtain the moisture content of the roller brush 210 during the drying process of the roller brush 210.

[0040] Please also refer to Figure 3 The base 100 includes a base body 10, a blocking assembly, and a drying assembly. An air outlet duct 11 is formed within the base body 10, and the drying assembly is located within the air outlet duct 11. The blocking assembly is coupled to the base body 10 and includes a water-blocking, breathable member 21. When the base 100 performs the first and second drying operations, the air outlet duct 11 is configured to form a drying channel with an air outlet 13 directed toward the roller brush 210. When the drying assembly is activated, external airflow is drawn through the air outlet 13 of the drying channel toward the roller brush 210, thereby drying the roller brush 210.

[0041] Specifically, the seat body 10 includes an upper seat 15 and a lower seat 17, and the upper seat 15 and the lower seat 17 are surrounded to form an air outlet channel 11. Optionally, the drying component can only include a fan 31, which is used to drive the external air flow to flow through the air outlet channel 11 and then flow out (the air flow along the air outlet channel 11). Figure 1 Alternatively, the fan 31 and the heating element 32 may be included, and the heating element 32 is used to heat the airflow flowing through the air outlet channel 11.

[0042] When the base 100 performs the first drying operation, the drying component works, and the water-blocking and breathable member 21 at least partially closes the air outlet 13. The water-blocking and breathable member 21 has a ventilation function. Under the action of the drying component, the air flow can pass through the water-blocking and breathable member 21 and the uncovered air outlet 13, or blow toward the roller brush 210 through the water-blocking and breathable member 21 to dry the roller brush 210. In addition, the water-blocking and breathable member 21 also has a water-blocking function. Since the water-blocking and breathable member 21 at least partially closes the air outlet 13, the amount of sewage flowing into the air outlet channel 11 can be effectively reduced under the blocking effect of the water-blocking and breathable member 21, so as to reduce the chance of sewage contacting the drying component or other components in the base 10, thereby preventing the drying component or other components from leaking electricity, thereby reducing the safety risks of the cleaning device 1 and its base 100.

[0043] Understandably, due to the ventilation effect of the water-blocking and breathable member 21, regardless of whether the water-blocking and breathable member 21 completely closes the air outlet 13, the airflow from the air outlet channel 11 can be blown toward the roller brush 210. In other words, the present application can reduce the safety hazards of the cleaning device 1 while ensuring that the roller brush 210 has a high drying efficiency.

[0044] In addition, to ensure that the roller brush 210 can be fully dried, during the process of the base 100 performing the first drying operation and the second drying operation, the roller brush 210 rotates relative to the base 100 around the rotation axis 22 of the roller brush 210 itself, so that the airflow can contact the roller brush 210 over a large range, thereby allowing all positions of the roller brush 210 to be dried.

[0045] Optionally, the water-blocking breathable member 21 can be made of cloth, sponge, rope-like braid, or other materials. Preferably, the water-blocking breathable member 21 is a water-absorbing member. Therefore, while the water-blocking breathable member 21 blocks water, it can also absorb sewage, thereby preventing the sewage from rebounding and splashing after contacting the water-blocking breathable member 21.

[0046] When the base 100 performs the second drying operation, the water-blocking and breathable member 21 opens at least part of the air outlet 13. Specifically, the threshold value can be set according to demand. It only needs to be ensured that when the water content of the roller brush 210 is greater than the set threshold, the roller brush 210 can rotate to throw out more sewage, and most of the sewage thrown out can be blocked by the water-blocking and breathable member 21. When the water content of the roller brush 210 is less than or equal to the set threshold, the amount of sewage that can be thrown out by the roller brush 210 is very small, or even negligible. Since the water content of the roller brush 210 is small when the base 100 performs the second drying operation, setting the water-blocking and breathable member 21 to open at least part of the air outlet 13 at this time can reduce the obstruction of the water-blocking and breathable member 21 on the airflow, so that the airflow can be blown quickly and in large quantities to the roller brush 210. Therefore, the cleaning device 1 in this application can further improve the drying efficiency of the roller brush 210 while ensuring low safety hazards.

[0047] Furthermore, when the base 100 performs the first drying operation, the water-blocking and breathable member 21 completely closes the air outlet 13. This ensures that the cleaning device 1 can dry the roller brush 210 while effectively preventing sewage from entering the interior of the base 10 through the air outlet 13, thereby reducing safety risks for the cleaning device 1. When the base 100 performs the second drying operation, the water-blocking and breathable member 21 completely opens the air outlet 13. This increases the air volume of the air outlet 11 while allowing only minimal or no sewage to be thrown into the air outlet channel 11 from the air outlet 13, thereby improving the drying efficiency of the roller brush 210.

[0048] Optionally, the water-blocking breathable member 21 can open or close the air outlet 13 by moving along the axial direction of the air outlet 13, or the water-blocking breathable member 21 can open or close the air outlet 13 by moving within the plane where the air outlet 13 is located.

[0049] Specifically, the blocking assembly further includes a rotating shaft 22, and the water-blocking and breathable member 21 is a flexible member with one end wound around the rotating shaft 22. When the base 100 performs a first drying operation, the rotating shaft 22 is controlled to rotate in a first direction and wind around the water-blocking and breathable member 21. The rotating shaft 22 is controlled to move downward in the direction of gravity until the water-blocking and breathable member 21 completely closes the air outlet 13. When the base 100 performs a second drying operation, the rotating shaft 22 is controlled to rotate in a second direction opposite to the first direction, releasing the water-blocking and breathable member 21. The rotating shaft 22 is controlled to move downward in the direction of gravity until the water-blocking and breathable member 21 completely opens the air outlet 13.

[0050] On the base 10, the air outlet 13 is generally located at the upper portion of the base 10. When the base 100 completes the second drying operation, the rotating shaft 22 and the water-blocking breathable member 21 are both located at the bottom of the base 10, and only one end of the water-blocking breathable member 21 is wound around the rotating shaft 22, with the rest of the water-blocking breathable member 21 stacked together. When the base 100 performs the first drying state, the rotating shaft 22 is controlled to rotate in a first direction and move upward in the direction of gravity. During the rotation of the rotating shaft 22, the portion of the water-blocking breathable member 21 wound around the rotating shaft 22 increases, and the water-blocking breathable member 21 can gradually rise and unfold under the drive of the rotating shaft 22. When the water-blocking breathable member 21 rises to a position that completely covers the air outlet 13, the rotating shaft 22 stops rotating and stops moving.

[0051] Please refer again Figure 1 When the base 100 performs the second drying state, the rotating shaft 22 is controlled to rotate in the second direction (clockwise, such as Figure 1 The rotating shaft 22 is controlled to move downward along the direction of gravity, and during the rotation of the rotating shaft 22, the portion of the water-blocking breathable member 21 released increases, and the water-blocking breathable member 21 can gradually move downward and stack under the drive of the rotating shaft 22. When the water-blocking breathable member 21 moves down to the position where the air outlet 13 is fully opened, the rotating shaft 22 stops rotating and stops moving. By setting the rotating shaft 22 to drive the water-blocking breathable member 21 to move up and down, and the water-blocking breathable member 21 to be stacked and unfolded to jointly realize the opening and closing of the air outlet 13, not only is the operation simpler, but the space occupied by the water-blocking breathable member 21 can also be reduced, thereby effectively reducing the production cost of the cleaning equipment 1.

[0052] Please also refer to Figure 4 and Figure 5 Optionally, the rotating shaft 22 can be rotated and moved up and down by human power or control of the driving member 26. Preferably, the blocking assembly further includes a driving member 26, a gear 23, and a rack 24. The driving member 26 is in transmission connection with the rotating shaft 22. The gear 23 is sleeved and fixed on the rotating shaft 22. The rack 24 extends in the direction of gravity and meshes with the gear 23. The rotating shaft 22 rotates under the action of the driving member 26 and moves up and down under the action of the gear 23.

[0053] Specifically, when the base 100 performs a first drying operation, the driver 26 drives the rotating shaft 22, which in turn drives the gear 23 to rotate in a first direction, allowing the gear 23 to roll on the rack 24 and gradually move the rotating shaft 22 and the water-blocking breathable member 21 upward. When the base 100 performs a second drying operation, the driver 26 drives the rotating shaft 22, which in turn drives the gear 23 to rotate in a second direction, allowing the gear 23 to roll on the rack 24 and gradually move the rotating shaft 22 and the water-blocking breathable member 21 downward. The provision of the driver 26, gear 23, and rack 24 eliminates the need for manual operation and allows the rotating shaft 22 to move up and down stably, thereby enabling the water-blocking breathable member 21 to normally open and close the air outlet 13.

[0054] In some embodiments, the gear 23 and rack 24 are used together to form a transmission structure. This transmission structure can be one, two, or more sets. Preferably, the transmission structure is two sets, each disposed at either end of the rotating shaft 22. In other words, there are two gears 23 and two racks 24, each of which is fixed to opposite ends of the rotating shaft 22, and the two racks 24 correspond to and work in conjunction with the two gears 23. This further improves the stability of the movement of the rotating shaft 22.

[0055] Furthermore, the blocking assembly further includes a guide member 25, which is coupled to the base 10 and configured to guide the shaft 22 to move up and down. Under the action of the guide member 25, the shaft 22 can stably move up and down, thereby preventing the shaft 22 from shaking and causing abnormal opening and closing of the air outlet 13.

[0056] Furthermore, the guide member 25 defines a guide channel 252 extending in the direction of gravity, through which the rotating shaft 22 passes. Specifically, the edge of the guide channel 252 guides the rotating shaft 22 to prevent it from shaking during its vertical movement. Furthermore, the relatively simple design of the guide channel 252 further enhances the ease of manufacturing of the cleaning device 1.

[0057] Of course, the manner in which the water-blocking and breathable member 21 opens and closes the air outlet 13 is not limited to the above-described one. In other embodiments, the water-blocking and breathable member 21 may further comprise a plurality of blades, wherein the plurality of blades are controlled to rotate relative to the base 10 to collectively and completely close the air outlet 13, and at least one of the plurality of blades rotates in the opposite direction relative to the base 10 to at least partially open the air outlet 13.

[0058] Alternatively, the blocking assembly can be disposed outside the base 10 and can open or close the air outlet 13 from outside the base 10, or it can be disposed within the air outlet passage 11. Preferably, the blocking assembly is located within the air outlet passage 11 and can open or close the air outlet 13 from within the base 10. Positioning the blocking assembly within the air outlet passage 11 not only protects the base 10 from damage but also prevents exposure, thereby enhancing the aesthetics of the cleaning device 1.

[0059] It is worth mentioning that in the seat 10, the aperture of the air outlet 13 of the air outlet channel 11 is smaller than the aperture of other positions in the air outlet channel 11. The blocking breathable member 21 is arranged in the air outlet channel 11 and is aligned with the air outlet 13 in the flow direction of the airflow, and other components in the blocking assembly, such as the rack 24, the driving member 26 and the guide member 25 are arranged at a position where the airflow avoids. In this way, the rack 24, the driving member 26 and the guide member 25 can be prevented from blocking the flow of the airflow, while also ensuring that the blocking breathable member 21 can fully open or completely close the air outlet 13.

[0060] The above-mentioned cleaning device 1 and its base 100, when the base 100 performs the first drying operation, the air outlet channel 11 itself is constructed to form a drying channel with the air outlet 13 facing the roller brush 210, and the water-blocking and breathable member 21 at least partially closes the air outlet 13. The water-blocking and breathable member 21 has a ventilation function, so that airflow can still pass through the water-blocking and breathable member 21 and blow toward the roller brush 210 to dry the roller brush 210. In addition, the water-blocking and breathable member 21 also has a water-blocking function. Since the water-blocking and breathable member 21 at least partially closes the air outlet 13, the water-blocking and breathable member 21 can effectively reduce the amount of sewage flowing into the air outlet channel 11 under the action of the water-blocking and breathable member 21, thereby reducing the safety hazards of the cleaning device 1 and its base 100.

[0061] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
