Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning equipment, in particular to a surface cleaning system with a drying function. Background Art
[0002] With the development of technology, the types of surface cleaning equipment are increasing. Various surface cleaning equipment has gradually entered people's homes and become common appliances for cleaning floors. Existing handheld floor scrubbers are generally equipped with a base. When placed on the base, the handheld floor scrubber can be charged and self-cleaned.
[0003] To prevent wastewater from being thrown out of the base during self-cleaning, some technical solutions, such as the floor scrubber disclosed in CN216090337U, have a shielding member installed at the front of the base. This shielding member seals the gap between the roller brush cover of the handheld floor scrubber and the front end of the base, positioning the cleaning element in a relatively enclosed space. This allows the discarded wastewater to flow back into the cleaning tank. However, because the cleaning element is located in a relatively enclosed space, the water vapor generated by the cleaning element during drying is difficult to discharge, resulting in a longer drying cycle for the cleaning element. Furthermore, after drying, the humidity in this enclosed space is high, which can easily cause the cleaning element to produce odors or breed mold, which is not conducive to improving the user experience.
[0004] In addition, to improve the drying efficiency of the cleaned items, hot air is generally used for drying. To accelerate the flow of the hot air, the fan on the handheld floor scrubber is also activated during hot air drying. The water vapor carried by the hot air will condense into water droplets during the flow process and fall into the sewage bucket. Due to the high temperature of the hot air flow, the hot air flow does not completely cool to room temperature when passing through the sewage bucket, resulting in the airflow after passing through the sewage bucket still carrying a large amount of water vapor. This part of the water vapor will condense into water droplets when passing through the fan and be retained in the fan. This can easily cause the fan to be damaged by water, which is not conducive to ensuring the performance stability of the fan. Utility Model Content

[0013] Preferably, the front side of the base is provided with a front baffle connected to the side baffle as an integral structure, the front end of the shielding member is attached to the front baffle, and the rear end of the shielding member extends obliquely upward and can interfere with the front of the cover.
[0014] Preferably, the front baffle is higher than or flush with the side baffles.
[0015] Preferably, the length of the shielding member is less than or equal to the left-right width of the base.
[0016] Preferably, when the surface cleaning device is placed on the base, there is a gap between the cleaning member and the front baffle, and the shielding member that contacts the cover covers the gap between the cleaning member and the front baffle.
[0017] Preferably, the shielding member includes a mounting portion located at the front end, a resistance portion located at the rear end, and a connecting portion connecting the mounting portion and the resistance portion, the resistance portion is thinner than the connecting portion, the connecting portion has an arc-shaped cross-section perpendicular to the axial direction of the cleaning member, and the connecting portion extends backward at most to the vertical plane where the front edge of the cleaning member is located.
[0018] Preferably, the interference portion extends obliquely upward from front to back and is not lower than the cleaning member; and / or, an inclination angle θ of the interference portion relative to the horizontal direction is 0° to 15°.
[0019] Preferably, the interference portion gradually becomes thinner from front to back.
[0020] Preferably, the drying device is arranged inside the base, the front baffle is provided with an air outlet cavity connected to the air outlet end of the drying device, the front baffle is provided with an air outlet connecting the air outlet cavity and the cleaning tank, and at least part of the shielding member is located above the air outlet.
[0021] After adopting the above technical solution, the utility model has the following advantages:
[0022] 1. In the surface cleaning system provided by the present invention, when the surface cleaning device is placed on the base, the shielding member covers at least a portion of the cleaning member. Since the shielding member extends along the axial direction of the cleaning member, the sewage thrown out by the cleaning member can fall back into the cleaning tank under the blocking effect of the shielding member, thereby preventing the cleaning sewage of the cleaning member from splashing out of the cleaning tank.
[0023] Side baffles are provided on the left and right sides of the cleaning tank. When the surface cleaning device is placed on the base, a ventilation gap is provided between the side baffle and the side wall of the floor brush on the same side. That is, the floor brush, the shielding member, and the side baffles combine to form a cleaning space open on both sides. When the drying device dries the cleaning member, the drying airflow generated by the drying device can be discharged from the base through the ventilation gap after flowing through the outer peripheral surface of the cleaning member. That is, the drying airflow can carry the moisture of the cleaning member out of the cleaning space, thereby improving the air flow inside and outside the cleaning space, thereby improving the drying efficiency and effect of the cleaning member. In addition, because the cleaning space can be connected to the outside air through the ventilation gap, the humidity in the cleaning space is basically the same as that of the outside air after drying is completed, which can prevent the cleaning member from easily generating odor or breeding mold in a humid enclosed space, thereby improving the user experience.
[0024] When the cleaning parts are dried by the blower, the drying airflow flowing through the outer surface of the cleaning parts is sucked away by the suction of the blower, which can accelerate the flow of the drying airflow, thereby improving the drying efficiency of the cleaning parts. When the drying device adopts hot air drying, the hot airflow with a higher temperature generated by the drying device can accelerate the drying speed of the cleaning parts. The outside air is introduced into the cleaning space from the ventilation gap under the suction of the blower and forms a cold airflow with a lower temperature. Since the temperature of the cold airflow is lower, the hot airflow flowing through the cleaning parts and the introduced cold airflow mix to accelerate the cooling of the airflow, so that the water vapor carried by the hot airflow can basically condense into water droplets before entering the sewage bucket. The water droplets fall into the sewage bucket when following the airflow into the sewage bucket, so that the airflow after passing through the sewage bucket basically does not carry water vapor, thereby avoiding the water vapor flowing into the fan with the airflow condensing into water droplets in the fan and falling into the fan, thereby reducing the risk of the fan being damaged by water and improving the performance stability of the fan.
[0025] 2. The front end of the shielding member is connected to the front side of the base. When the surface cleaning device is placed on the base, the rear end of the shielding member contacts the cover on the floor brush, so that the shielding member can basically cover the part of the cleaning member exposed from the cover. When the cleaning member is self-cleaning, the sewage thrown out falls back into the cleaning tank under the blocking effect of the shielding member.
[0026] The shielding member only forms ventilation openings between the left and right ends and the corresponding side panels, and the ventilation openings are connected to the ventilation gaps to form side ducts. When the drying device uses hot air to dry the cleaning parts, the shielding member can effectively prevent the hot air flow from dissipating quickly. The hot air flow can flow to the cleaning parts under the guidance of the shielding member, ensuring the drying effect of the hot air flow on the cleaning parts and avoiding the situation where the hot air flow dissipates quickly and causes the cleaning parts to dry more slowly. When the fan is working, the outside air flows in from the side duct to form a cold air flow. The ventilation openings and ventilation gaps are used to ensure the flow rate of the cold air flow, so that the water vapor carried by the hot air flow can be fully condensed when encountering the cold air flow, thereby avoiding the situation where the water vapor follows the air flow into the fan and condenses, while ensuring the drying effect of the cleaning parts and the water vapor condensation effect.
[0027] 3. A front baffle is provided on the front side of the base, which is integrated with the side baffles to enhance their structural strength. The front end of the shield is attached to the front baffle, while the rear end of the shield extends diagonally upward. The shield is rationally designed so that it contacts the front of the cover when the surface cleaning device is placed on the base. This allows the shield to simultaneously block discarded wastewater and introduce an appropriate amount of cool air to assist in drying. This also reduces the difficulty of placing the surface cleaning device on the base.
[0028] 4. The front baffle is preferably higher than or flush with the side baffle. The height of the front baffle ensures that the size of the ventilation opening is appropriate, thereby ensuring that the flow rate of the introduced cold air flow is appropriate. On the one hand, it avoids the situation where excessive cold air flow is introduced, causing the hot air flow to dissipate quickly and resulting in low drying efficiency of the cleaning parts. On the other hand, it also avoids the situation where insufficient cold air flow is introduced, causing water vapor to fail to condense in time.
[0029] 5. The length of the shielding member is preferably less than or equal to the left and right widths of the base. The length of the shielding member is reasonably set so that ventilation openings can be formed between the left and right ends of the shielding member and the corresponding side panels.
[0030] 6. When the surface cleaning device is placed on the base, a gap exists between the cleaning element and the front baffle. The drying airflow generated by the drying device can flow through this gap between the cleaning element and the front baffle, ensuring a drying effect on the cleaning element. The shielding member, which contacts the cover, covers the gap between the cleaning element and the front baffle, preventing the hot air generated by the drying device from quickly dissipating through this gap.
[0031] 7. The shielding member includes a mounting portion, an interfering portion, and a connecting portion. The mounting portion attaches the shielding member to the front baffle. The interfering portion interferes with the cover on the floor brush when the surface cleaning device is placed on the base. The connecting portion is located between the mounting portion and the interfering portion and can cover the gap between the front baffle and the cover. The specific structure of the shielding member is appropriately designed to ensure that it meets the requirement of covering at least part of the cleaning member.
[0032] The interference portion is thinner than the connecting portion, making it easier for the interference portion to undergo elastic deformation than the connecting portion, so that the interference portion can smoothly interfere with the cover when the surface cleaning device is placed on the base. The cross-sectional shape of the connecting portion along a direction perpendicular to the axial direction of the cleaning member is preferably arc-shaped, so that the sewage thrown out by the cleaning member can quickly flow back into the cleaning tank along the inner surface of the connecting portion after splashing onto the connecting portion. The connecting portion extends backward at most to the vertical plane where the leading edge of the cleaning member is located, that is, the rear end of the connecting portion will not extend backward beyond the frontmost point of the cleaning member, so that the cleaning member can smoothly enter the cleaning tank when the surface cleaning device is placed on the base, avoiding the connection portion from hindering the cleaning member from entering the cleaning tank, and appropriately reducing the difficulty of placement for the user.
[0033] 8. The interference portion extends obliquely upward from front to back and is not lower than the cleaning member. The inclination angle θ of the interference portion relative to the horizontal direction is 0° to 15°. The structure of the interference portion is reasonably set so that the cleaning member can smoothly enter the cleaning tank when the surface cleaning device is placed on the base, and the interference portion can smoothly interfere with the cover on the floor brush, avoiding the situation where the cleaning member contacts the interference portion when entering the cleaning tank and presses the interference portion into the cleaning tank.
[0034] 9. The resistance part preferably becomes thinner from front to back. The change in thickness of the resistance part further increases the elastic deformation of the resistance part, thereby further improving the elastic effect of the resistance part, so that the resistance part can smoothly resist the cover when the surface cleaning device is placed on the base.
[0035] 10. The drying device is disposed within the base, and the front baffle is provided with an air outlet cavity and an air outlet. The drying airflow generated by the drying device flows through the air outlet cavity and the air outlet to the cleaning member to dry the cleaning member. At least a portion of the shielding member is positioned above the air outlet. A portion of the drying airflow blown through the air outlet can flow through the inner surface of the shielding member and dry the shielding member, thereby maintaining the shielding member in a dry state after drying.

[0058] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following terms indicating orientations or positional relationships, such as "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," are based solely on the orientations or positional relationships shown in the accompanying drawings and are intended solely for the purpose of facilitating and simplifying the description of the present invention. They do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation, and therefore should not be construed as limiting the present invention.
[0059] Example 1
[0060] Combine Figures 1 to 12 The first embodiment of the present invention provides a surface cleaning system with a drying function, comprising:
[0061] A surface cleaning device 10 is provided with a floor brush 100 and a blower 210, wherein the floor brush 100 is provided with a cleaning member 110 for cleaning the surface to be cleaned;
[0062] A base 20 is provided with a cleaning tank 510, and a shielding member 300 is provided on the front side of the cleaning tank 510 for covering at least part of the cleaning member 110;
[0063] A drying device 400 for drying the cleaning element 110;
[0064] The shielding member 300 extends along the axial direction of the cleaning member 110;
[0065] Side baffles 520 approximately perpendicular to the axial direction of the cleaning member 110 are provided on the left and right sides of the cleaning tank 510 , and a ventilation gap 531 is provided between the side baffles 520 and the side wall of the floor brush 100 on the same side.
[0066] When the drying device 400 dries the cleaning element 110, the drying airflow generated by the drying device 400, after flowing through the outer peripheral surface of the cleaning element 110, can be discharged from the base 20 through the ventilation gap 531. In other words, the moisture in the cleaning element 110 can be discharged from the cleaning space along with the drying airflow, thereby improving the air flow inside and outside the cleaning space, thereby improving the drying efficiency and effect of the cleaning element 110. In addition, because the cleaning space is connected to the outside air through the ventilation gap 531, the humidity in the cleaning space is substantially the same as that of the outside air after drying is completed. This can prevent the cleaning element 110 from generating odors or breeding mold in a humid enclosed space, thereby improving the user experience.
[0067] When the self-cleaning element 110 is dried by the fan 210, the drying airflow flowing through the outer peripheral surface of the cleaning element 110 is sucked away by the suction force of the fan 210, which can accelerate the flow of the drying airflow and thus increase the drying speed of the cleaning element 110. When the drying device 400 adopts hot air drying, the hot air flow with a higher temperature generated by the drying device 400 can accelerate the drying efficiency of the cleaning part 110. The outside air is introduced into the cleaning space from the ventilation gap 531 under the suction of the fan 210 and forms a cold air flow with a lower temperature. Since the temperature of the cold air flow is relatively low, the hot air flow flowing through the cleaning part 110 and the introduced cold air flow are mixed to accelerate the cooling of the air flow, so that the water vapor carried by the hot air flow can basically condense into water droplets before entering the sewage bucket. When the water droplets follow the air flow into the sewage bucket, they fall into the sewage bucket, so that the air flow after passing through the sewage bucket basically does not carry water vapor, thereby avoiding the water vapor following the air flow into the fan 210 condensing into water droplets in the fan 210 and falling in the fan 210, thereby reducing the risk of the fan 210 being damaged by water and improving the performance stability of the fan 210.
[0068] Combine Figure 1 、 Figure 2 In this embodiment, the surface cleaning device 10 is described using a handheld floor scrubber as an example. The surface cleaning device 10 further includes a body 600, with a handle 610 provided at the top. The bottom of the body 600 is pivotally connected to the rear side of the floor brush 100 via a joint, allowing the body 600 to swing back and forth relative to the floor brush 100. The floor brush 100 includes a floor brush body 120 and a cover 130, which is removably mounted on the top side of the floor brush body 120. When the cover 130 is mounted on the top side of the floor brush body 120, the cover 130 cooperates with the floor brush body 120 to form a roller brush cavity 140 for mounting a cleaning member 110. The cleaning member 110 is removably mounted within the roller brush cavity 140. The front and bottom sides of the roller brush chamber 140 are open. When the cleaning member 110 is installed in the roller brush chamber 140, the cover 130 covers the top of the cleaning member 110. The bottom side of the cleaning member 110 protrudes downward from the bottom surface of the floor brush 100, allowing the cleaning member 110 to effectively clean the surface to be cleaned. The cleaning member 110 can adopt an existing single roller brush structure, a dual roller brush structure, or a crawler mop structure, without further limitation.
[0069] In this embodiment, a side plate 150 is provided at one end of the cleaning member 110. The side plate 150 is approximately perpendicular to the axial direction of the cleaning member 110. One end of the cleaning member 110 is rotatably mounted on the side plate 150 via a bearing, so that one end of the cleaning member 110 is supported by the side plate 150. The floor brush body 120 is provided with a frame plate 160 opposite to the side plate 150. When the cleaning member 110 is installed in the roller brush chamber 140, the side plate 150 and the frame plate 160 are arranged opposite each other and are respectively located on the left and right sides of the floor brush 100. The other end of the cleaning member 110 is supported by the frame plate 160, which is also approximately perpendicular to the axial direction of the cleaning member 110.
[0070] Combine Figure 4 The floor brush 100 is provided with a motor 710 for driving the cleaning member 110 to rotate. The motor 710 drives the cleaning member 110 to rotate through a transmission structure. Specifically, in this embodiment, the frame 160 is provided with a hinged joint 720 on the side facing the center of the floor brush 100. One end of the motor 710 is hinged to the frame 160 through the cooperation of the hinged joint 720 with the hinged shaft. The other end of the motor 710 is provided with a transmission head 730. The cleaning member 110 is hollow and a transmission hole is provided inside the cleaning member 110 to cooperate with the transmission head 730. When the cleaning member 110 is installed in the roller brush chamber 140, the motor 710 and the transmission head 730 are accommodated in the cleaning member 110 and the transmission head 730 is inserted into the transmission hole. The end of the cleaning member 110 facing the frame 160 is sleeved on the outside of the hinged joint 720 so that the other end of the cleaning member 110 is supported. The working motor 710 drives the cleaning member 110 to rotate around its own central axis through the cooperation between the transmission head 730 and the transmission hole. The rotating cleaning member 110 can effectively wipe the surface to be cleaned. As an alternative to this embodiment, the motor 710 can also be fixed to the frame 160; or, the motor 710 can also be arranged in the floor brush body 120, the transmission head 730 is arranged on one side of the frame 160, and a gear structure is provided between the motor 710 and the transmission head 730 for transmitting power. As an alternative to this embodiment, when the cleaning member 110 adopts a single roller brush structure, the motor 710 can also be directly installed inside the cleaning member 110. In this case, an electrical connection structure is provided between the floor brush body 120 and the cleaning member 110. When the cleaning member 110 is installed in the roller brush chamber 140, the motor 710 is connected to electricity through the electrical connection structure. When the cleaning member 110 adopts a double roller brush structure, the motor 710 for driving the cleaning member 110 can be arranged in one of the roller brushes, and a transmission assembly can be arranged between the two roller brushes; when the cleaning member 110 adopts a crawler mop structure, the motor 710 for driving the cleaning member 110 can be arranged in one of the roller bodies, and the roller body drives the other roller body to rotate synchronously through the mop.
[0071] Combine Figure 5The surface cleaning device 10 of this embodiment further includes a liquid supply assembly 800, which includes a clean water tank 810, a water pump 820, and a water diverter 830, which are arranged sequentially from upstream to downstream via a pipeline. The clean water tank 810 can be detachably mounted on the body 600, or can be detachably mounted on the floor brush body 120, or fixed to the bottom of the cover 130. The water pump 820 is disposed within the floor brush body 120. The water diverter 830 is disposed on the front side of the floor brush body 120 or on the bottom of the front cover 130. The water diverter 830 is provided with a plurality of water outlet holes spaced apart in the left-right direction, and the water outlet holes are disposed toward the cleaning element 110. The cleaning liquid in the clean water tank 810 flows to the water diverter 830 under the pumping action of the water pump 820. The cleaning liquid flowing into the water diverter 830 is sprayed from the water outlet holes onto the cleaning element 110, thereby allowing the cleaning element 110 to absorb the liquid and moisten it. As a preferred solution of this embodiment, the water distribution member 830 can adopt the existing technology of dividing a water inlet waterway into two N (N is a natural number) to divert the liquid into a structure with multiple water outlets. Of course, other components such as nozzles or nozzles that meet the liquid supply requirements can also be used instead of the water diversion component 830. As an improvement to this embodiment, the liquid supply component 800 can be provided with a heating component 840 upstream of the water diversion component 830. The heating component 840 is used to heat the liquid flowing through, and the heated liquid is sprayed out from the water diversion component 830. As an alternative to this embodiment, the liquid supply component 800 can also be provided with a spray component for spraying the cleaning liquid onto the surface to be cleaned on the basis of the water diversion component 830. The spray component is connected to the end of the pipeline through an electronic control valve. At this time, a ground spray button for the user to selectively operate can be provided on the handle 610. If the user presses the ground spray button, the electronic control valve opens, and the liquid supply component 800 can spray the cleaning liquid onto the surface to be cleaned through the spray component.
[0072] In this embodiment, the floor brush body 120 is provided with a sewage suction port 170 centered on the left and right sides. The sewage suction port 170 is located behind the roller brush chamber 140 and is connected to the roller brush chamber 140. The surface cleaning device 10 of this embodiment also includes a sewage suction assembly 200. The sewage suction assembly 200 includes a fan 210 and a sewage bucket 220. The sewage bucket 220 is detachably mounted on the body 600. A sewage suction channel is provided between the lower end of the body 600 and the floor brush body 120 to connect the sewage suction port 170 and the sewage bucket 220. The specific structure of the sewage bucket 220 can refer to the prior art and will not be described here. The fan 210 can be located at the upper end of the body 600, or it can be used as a component of the suction power source assembly. The suction power source assembly can be detachably mounted on the body 600. The suction power source assembly detached from the body 600 can be connected to a dust collection accessory for dry dust collection. When the fan 210 is working, it provides suction to form a negative pressure in the sewage bucket 220 and form a sewage suction airflow flowing from the sewage suction port 170 into the sewage bucket 220. The dirt at the sewage suction port 170 can flow into the sewage bucket 220 along the sewage suction airflow, thereby collecting the dirt.
[0073] In this embodiment, the floor brush 100 is further provided with a scraping member 180 for scraping the cleaning member 110. The scraping member 180 extends axially along the cleaning member 110. The scraping member 180 may be a single scraping bar structure, a single comb tooth structure, or a combination of a scraping bar and comb teeth. The specific structure of the scraping member 180 is not particularly limited. Furthermore, a floor scraper 190 is further provided at the lower edge of the front side of the floor brush body 120. The floor scraper 190 extends axially along the cleaning member 110, with the leading edge of the floor scraper 190 extending downward and capable of contacting the surface to be cleaned. The water diverter 830, the scraper 180, the sewage suction port 170 and the floor scraper 190 are distributed sequentially from top to bottom. The water diverter 830 and the scraper 180 can be arranged together at the bottom of the cover 130, or together at the front side of the floor brush body 120. They can also be arranged separately and the water diverter 830 is arranged at the bottom of the cover 130 and the scraper 180 is arranged at the front side of the floor brush body 120. There are no excessive restrictions on the installation positions of the water diverter 830 and the scraper 180.
[0074] The surface cleaning device 10 also includes a battery pack 910 and a control board 920. The battery pack 910 is used to supply power to the electrical components of the surface cleaning device 10. The control board 920 is used to control the entire system. Electrical components such as the motor 710, fan 210, water pump 820, and drying device 400 are controlled by the control board 920.
[0075] Combine Figure 6 、 Figure 7 The rear side of the base 20 is provided with an upwardly projecting boss 540. A charging unit 550 is located at the top of the boss 540 and can be connected to the mains via a power cord. A power connector 620 is located at the lower end of the body 600. The power connector 620 and the charging unit 550 can be removably plugged into each other. When the surface cleaning device 10 is placed on the base 20, the power connector 620 plugs into the charging unit 550, thereby charging the battery pack 910.
[0076] The base 20 adopts a shell structure, and the front side of the top wall of the base 20 is concave to form a cleaning tank 510. The side baffles 520 are located at the front of the left and right sides of the base 20, and are combined with the cleaning tank 510 to form a cleaning tank 510. Figure 8 The distance L1 between the left and right side baffles 520 is slightly greater than the maximum width W of the entire floor brush 100. When the surface cleaning device 10 is placed on the base 20, the floor brush 100 is located between the two side baffles 520 in the left-right direction and is approximately centered relative to the base 20. The left and right side baffles 520 are both approximately perpendicular to the axial direction of the cleaning member 110. The rear edges of the side baffles 520 extend rearward across the entire cleaning member 110. A ventilation gap 531 is defined between one of the side baffles 520 and the side panel 150, and a ventilation gap 531 is also defined between the other side baffle 520 and the frame panel 160.
[0077] The front side of the base 20 is provided with an upwardly projecting front baffle 560. The top edge of the front baffle 560 is higher than the top wall of the base 20. The front baffle 560 is integrally connected to the left and right side baffles 520, forming a U-shaped baffle structure. This improves the overall structural strength of the base 20. In this embodiment, the front baffle 560 is flush with the side baffles 520, i.e., the top edge of the front baffle 560 is flush with the top edge of the side baffles 520.
[0078] Combine Figure 9 、 Figure 10 The front end of the shielding member 300 is attached to the front baffle 560 of the base 20, and the rear end of the shielding member 300 is suspended in the air. The length of the shielding member 300 is less than the left and right widths of the base 20. Specifically, the length of the shielding member 300 is slightly less than the distance between the two side baffles 520. When the surface cleaning device 10 is placed on the base 20, the rear end of the shielding member 300 contacts the cover 130 on the floor brush 100, so that the portion of the cleaning member 110 exposed from the front baffle 560 can be covered. Ventilation openings 532 are formed between the left and right ends of the shielding member 300 and the corresponding side baffles 520. The ventilation openings 532 and the ventilation gaps 531 are in communication, and the two together form side air ducts 530. When the drying device 400 dries the cleaning member 110, the shielding member 300 effectively prevents the rapid dissipation of the hot air flow. Guided by the shielding member 300, the hot air flow can flow toward the cleaning member 110, ensuring the hot air flow's drying effect on the cleaning member 110 and preventing the rapid dissipation of the hot air flow, which would otherwise slow the drying of the cleaning member 110. When the fan 210 is operating, outside air flows in from the side duct 530 to form a cold air flow. The ventilation opening 532 and ventilation gap 531 ensure the flow rate of the cold air flow, allowing moisture carried by the hot air flow to fully condense when it encounters the cold air flow. This prevents moisture from flowing into the fan 210 and condensing, while ensuring both the drying effect and moisture condensation effect on the cleaning member 110. As an alternative to this embodiment, the length of the shielding member 300 can also be set to be equal to the left and right widths of the base 20.
[0079] The height relationship between the front baffle 560 and the side baffles 520 ensures that the ventilation opening 532 is appropriately sized, thereby ensuring that the amount of cold air introduced is appropriately directed. This prevents excessive cold air from being introduced, which causes the hot air to dissipate quickly and reduces the drying efficiency of the cleaning element 110. Furthermore, it prevents insufficient cold air from being introduced, which prevents moisture from being condensed in a timely manner. As an alternative to this embodiment, the front baffle 560 can also be positioned higher than the side baffles 520, i.e., the upper edge of the front baffle 560 is slightly higher than the upper edge of the side baffles 520.
[0080] The drying device 400 is installed in the cavity formed by the base 20, and an air inlet 541 is provided on the rear wall of the boss 540. In this embodiment, in order to improve the drying efficiency, the drying device 400 preferably adopts hot air drying. Specifically, the drying device 400 includes an airflow generating module 410 arranged upstream and a heating module 420 arranged downstream. The airflow generating module 410 works to form an airflow flowing downstream, and the heating module 420 heats the airflow flowing through to form a hot air flow that continues to flow downstream. The airflow generating module 410 can adopt an existing vortex fan module, etc., and there are no excessive restrictions here; the heating module 420 can adopt a heating wire structure, etc., and there are no excessive restrictions here.
[0081] The front baffle 560 includes a front plate 561 and a rear plate 562 spaced apart from each other and connected at the top. An air outlet cavity 563 is formed between the front plate 561 and the rear plate 562. The bottom of the base 20 is provided with an air guide channel 570 for guiding the airflow generated by the drying device 400 into the air outlet cavity 563. The rear end of the air guide channel 570 communicates with the port at the air outlet end of the drying device 400, and the front end of the air guide channel 570 communicates with the air outlet cavity 563. The rear plate 562 of the front baffle 560 is also provided with a plurality of air outlets 564 spaced apart in the left-right direction. The airflow flowing into the air outlet cavity 563 ultimately flows through the air outlets 564 to the cleaning member 110.
[0082] In this embodiment, the shielding member 300 includes a mounting portion 310 at the front end, a resisting portion 320 at the rear end, and a connecting portion 330 connecting the mounting portion 310 and the resisting portion 320. Specifically, the mounting portion 310, the connecting portion 330, and the resisting portion 320 are arranged from front to back and are sequentially connected. The mounting portion 310 has a mounting groove 311 with an open bottom side that mates with the top side of the front baffle 560. The mounting portion 310 is attached to the front baffle 560 through the engagement of the mounting groove 311 with the front baffle 560. The connecting portion 330 has an arc-shaped cross-section perpendicular to the axial direction of the cleaning member 110. The connecting portion 330 extends obliquely upward along the arc from front to back. The resisting portion 320 extends rearward from the upper edge of the connecting portion 330. The resisting portion 320 is arranged higher than or flush with the upper edge of the cleaning member 110. In addition, the interference portion 320 is preferably thinner than the connecting portion 330, that is, the thickness of the interference portion 320 is preferably less than the thickness of the connecting portion 330. Specifically in this embodiment, the shielding member 300 adopts a combined structure, wherein the mounting portion 310 and the connecting portion 330 can be made of plastic materials such as plastic and resin, and the interference portion 320 can be made of elastic materials such as rubber and silicone. As an alternative to this embodiment, the shielding member 300 can be made of elastic materials such as silicone or rubber as a whole. Furthermore, the interference portion 320 extends horizontally from front to back, and the thickness of the interference portion 320 is consistent from front to back. Combined Figure 11As an alternative to this embodiment, the interference portion 320 may gradually become thinner from front to back, that is, the thickness of the interference portion 320 gradually decreases from front to back. Figure 12 As another alternative to this embodiment, the interference portion 320 may extend obliquely upward from front to back, and the inclination angle θ of the interference portion 320 relative to the horizontal direction is 0° to 15°. Specifically, θ may be set to a reasonable value such as 0°, 1°, 3°, 5°, 7°, 10°, 12°, or 15°. As another alternative to this embodiment, the interference portion 320 not only gradually becomes thinner from front to back, but also extends obliquely upward from front to back. As an alternative to this embodiment, the thickness of the interference portion 320 may also be set to be equal to the thickness of the connecting portion 330.
[0083] In order to reduce the difficulty for the user to place the surface cleaning device 10 on the base 20, in this embodiment, the connecting portion 330 extends backward at most to the vertical plane where the front edge of the cleaning member 110 is located, that is, the rear end of the connecting portion 330 will not extend backward beyond the frontmost point of the cleaning member 110, so that the cleaning member 110 can smoothly enter the cleaning tank 510 when the surface cleaning device 10 is placed on the base 20, which can appropriately reduce the difficulty for the user to place the surface cleaning device 10. Figure 10 In the figure, straight line L1 represents the position of the rear edge of the connecting portion 330, point E represents the front edge of the cleaning member 110, straight line L2 represents the vertical plane where point E is located, and straight line L1 is located in front of straight line L2.
[0084] In this embodiment, when the surface cleaning device 10 is placed on the base 20, a certain gap is formed between the cleaning member 110 and the front baffle 560. The shielding member 300, which contacts the cover 130, can cover the gap between the cleaning member 110 and the front baffle 560. The drying airflow generated by the drying device 400 can flow between the cleaning member 110 and the front baffle 560 through the gap, thereby ensuring a drying effect on the cleaning member 110. The shielding member 300, which contacts the cover 130, covers the gap between the cleaning member 110 and the front baffle 560, preventing the hot air generated by the drying device 400 from quickly dissipating through the gap.
[0085] In this embodiment, at least a portion of the shielding member 300 is positioned above the air outlet 564 on the front baffle 560. A portion of the dry airflow exiting the air outlet 564 can flow through the inner surface of the shielding member 300 and dry the shielding member 300, thereby maintaining a dry state even after drying. In this embodiment, the connecting portion 330 of the shielding member 300 is positioned directly above the air outlet 564, guiding the hot airflow exiting the air outlet 564.
[0086] When the surface cleaning device 10 is working, the motor 710 drives the cleaning element 110 to rotate, and the liquid supply component 800 provides cleaning liquid to the cleaning element 110. The cleaning element 110 absorbs the liquid and moistens it, then wipes the surface to be cleaned. The fan 210 provides suction to form a sewage suction airflow that flows from the sewage suction port 170 to the sewage bucket 220. The dirt squeezed out of the cleaning element 110 by the scraping element 180 can be sucked into the sewage bucket 220 along the sewage suction airflow.
[0087] Combine Figure 1 、 Figure 3 、 Figure 10 After the surface cleaning device 10 finishes working, the surface cleaning device 10 is placed on the base 20. At this time, the charging component 550 in the base 20 is plugged into the power connection component 620 in the body 600 to charge the battery pack 910. The floor scraper 190 is against the rear edge of the cleaning tank 510, the cleaning component 110 is located in the cleaning tank 510, and the interference portion 320 of the shielding component 300 is against the cover 130 of the floor brush 100. The cover 130, the shielding component 300, the front baffle 560 and the floor scraper 190 are combined to form a cleaning space. The left and right sides of the cleaning space are connected to the outside through the side air duct 530. When the cleaning element 110 is self-cleaning, the motor 710 drives the cleaning element 110 to rotate, and the liquid supply assembly 800 supplies cleaning liquid to the cleaning element 110. The cleaning element 110, moistened with the liquid, is scraped and squeezed by the scraping element 180. The squeezed-out wastewater falls into the cleaning tank 510. The wastewater in the cleaning tank 510 can then flow into the wastewater bucket 220 under the suction action of the fan 210. After the self-cleaning is completed, the drying device 400 is activated. The hot air flow generated by the drying device 400 flows through the air guide channel 570 to the air outlet chamber 563. The hot air flow flowing into the air outlet chamber 563 is blown toward the cleaning element 110 through the air outlet 564. At the same time, the fan 210 operates to provide suction, and the hot air flow flowing through the outer peripheral surface of the cleaning element 110 is sucked away by the suction action of the fan 210. This accelerates the flow of the hot air flow, thereby improving the drying efficiency of the cleaning element 110. Under the suction of the fan 210, the outside air is introduced into the cleaning space through the side air duct 530 and forms a cold air flow. Since the temperature of the cold air flow is relatively low, the hot air flow flowing through the cleaning component 110 is mixed with the introduced cold air flow to accelerate the cooling of the air flow, so that the water vapor carried by the hot air flow can basically condense into water droplets before entering the sewage bucket 220. When the water droplets follow the air flow into the sewage bucket 220, they fall into the sewage bucket 220, so that the air flow after flowing through the sewage bucket 220 basically does not carry water vapor, thereby avoiding the water vapor following the air flow into the fan 210 condensing into water droplets in the fan 210 and falling into the fan 210, thereby reducing the risk of the fan 210 being damaged by water.
[0088] As an alternative to this embodiment, the fan 210 may not be activated when drying the cleaning member 110. In this case, the hot air generated by the drying device 400 flows toward the cleaning member 110 through the air outlet 564. The hot air flowing through the outer peripheral surface of the cleaning member 110 may flow out of the cleaning space through the side duct 530. That is, the hot air may carry moisture from the cleaning member 110 through the side duct 530 and be discharged from the cleaning space, thereby improving the air flow inside and outside the cleaning space, thereby improving the drying efficiency and effect of the cleaning member 110. In addition, because the cleaning space can be connected to the outside air through the side duct 530, the humidity in the cleaning space is substantially the same as that of the outside air after drying is completed, thereby preventing the cleaning member 110 from generating odor or breeding mold in a humid, enclosed space.
[0089] In addition to the above preferred embodiments, the present invention has other implementation methods. Those skilled in the art can make various changes and modifications based on the present invention. As long as they do not depart from the spirit of the present invention, they should all fall within the scope defined in the claims of the present invention.
