Description

Technical Field

[0001] This application relates to the field of razor cleaning technology, and more particularly to a razor cleaning device and razor system. Background Technology

[0002] As living standards improve, users are paying more and more attention to the cleaning and maintenance of shavers. As a result, cleaning devices specifically designed for shavers have emerged, aiming to automatically clean, disinfect, and dry the shaver head.

[0003] Currently, the core components of common shaver cleaning devices typically include a cleaning chamber for housing and cleaning the shaver head, and a wastewater tank connected to it for collecting waste liquid. To achieve the function of draining the liquid after cleaning, a common technical solution is to install a valve structure for drainage in the flow channel between the cleaning chamber and the wastewater tank.

[0004] However, the valve body structure in related technologies occupies a large space, which is not conducive to the miniaturization of shaver cleaning devices. Utility Model Content

[0005] This application provides a razor cleaning device and a razor system to address the issue that the valve body structure of the razor cleaning device in the aforementioned related technologies occupies a large space, which is not conducive to the miniaturization of the razor cleaning device.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a razor cleaning device, including a housing, a base, and a cleaning chamber; wherein the cleaning chamber is detachably disposed within the base, a drain outlet is provided at the bottom of the cleaning chamber, and a flow channel communicating with the drain outlet and a wastewater tank is provided within the base; the flow channel includes a horizontal section extending in a horizontal direction, an annular wall is provided within the horizontal section, the central axis of the annular wall coincides with the axis of the horizontal section, and a sealing surface is provided on the side of the annular wall away from the drain outlet; a drain valve is provided on the side of the sealing surface away from the drain outlet; the drain valve includes a valve core and a sealing head, the sealing head is fixed to the end of the valve core, the end of the valve core with the sealing head is disposed facing the sealing surface, and the valve core can extend and retract in a horizontal direction within the horizontal section; the valve core is configured to drive the sealing head to press against or disengage from the sealing surface of the annular wall when moving horizontally, so as to seal or open the flow channel.

[0008] The shaver cleaning device in this embodiment allows users to easily disassemble the cleaning chamber by setting a detachable base and a cleaning chamber, thereby cleaning the cleaning chamber, reducing the difficulty of cleaning the cleaning chamber, and ensuring that the cleaning chamber is clean and tidy.

[0009] By setting a flow channel connecting the drain outlet and the wastewater tank inside the base, and designing the key part of the flow channel as a horizontal extension section, and setting the valve core drive direction of the drain valve to horizontal extension, the entire drain valve can make full use of the horizontal space inside the housing, effectively avoiding the extra vertical height required by the traditional vertical arrangement of valves, thereby greatly compressing the vertical dimension of the housing, making the overall structure of the shaver cleaning device more compact, which is conducive to the miniaturization of the shaver cleaning device.

[0010] By setting a horizontally extending coaxial annular wall in the flow channel to form a sealing surface, and cooperating with the valve core to drive the sealing head to press the sealing surface, axial sealing of the flow channel is achieved. This allows the sealing head to uniformly bear the linear thrust from the valve core when closed, thus effectively avoiding the problems of uneven wear and poor sealing caused by lateral force. Moreover, the cooperation between the annular sealing surface and the sealing head forms a large-area contact seal, which significantly improves the reliability and durability of the seal and effectively prevents liquid leakage.

[0011] In one possible implementation, the flow channel includes a first vertical section and a second vertical section; wherein one end of the first vertical section is connected to a drain outlet and the other end is connected to a horizontal section; one end of the second vertical section is connected to the horizontal section and the other end is connected to a wastewater tank; a portion of the annular wall structure forms the inner wall of the second vertical section.

[0012] This design allows a portion of the annular wall structure to directly form the inner wall of the second vertical section, enabling the sealing surface and the second vertical section to be integrally formed. This reduces the number of independent sealing parts, lowers assembly difficulty and production costs, and eliminates the risk of leakage that may result from assembly gaps between parts, greatly improving the sealing reliability of the flow channel.

[0013] In one possible implementation, a smooth transition bend is formed between the first vertical segment and the horizontal segment.

[0014] This design eliminates the sharp edges of traditional right-angle turns through the bend, making the flow path smoother when the fluid changes from vertical to horizontal, effectively reducing flow resistance, improving wastewater discharge efficiency, helping to achieve rapid and thorough emptying, reducing sanitary dead corners, and preventing dirt residue and channel blockage.

[0015] In one possible implementation, the end of the horizontal section away from the drain outlet is provided with an extension wall extending in a direction away from the horizontal section; the extension wall forms an installation cavity with at least one opening, and the drain valve is disposed in the installation cavity and fixedly connected to the extension wall.

[0016] This design allows the drain valve to be compactly housed within the extended structure of the flow channel, eliminating the need for additional installation space within the base. This significantly optimizes the utilization of the base's internal space, resulting in a more compact device structure and a more rational layout.

[0017] In one possible implementation, the drain valve includes an electromagnet; wherein the valve core is configured as a metal rod, the metal rod being driven and connected to the electromagnet, the electromagnet being used to drive the metal rod to move horizontally; a sealing head is fixed to the end of the metal rod; when the electromagnet is de-energized, the sealing head is configured to press against the sealing surface to seal the drain outlet; when the electromagnet is energized, the magnetic force generated by the electromagnet drives the metal rod to move the sealing head away from the sealing surface to open the drain outlet.

[0018] By employing an electromagnet to drive the axial movement of a metal rod, the sealing head is automatically opened and closed at the drain outlet. Utilizing the magnetic force generated by the energized electromagnet as the power source, the system offers rapid response and precise control. When the electromagnet is de-energized, the sealing head automatically seals the drain outlet via gravity or a reset structure after the magnetic force disappears, creating a normally closed state and effectively preventing wastewater leakage. When drainage is needed, an electrical signal controls the electromagnet to quickly open the drain outlet. The entire process requires no manual operation from the user, thus avoiding the hygiene risks associated with hand contact with sewage. Furthermore, it automates and intelligently manages the drainage process, significantly improving the hygiene level and ease of use of the equipment.

[0019] In one possible implementation, a raised ring is provided at the end of the sealing head that contacts the sealing surface; the raised ring is used to form a line contact seal with the sealing surface.

[0020] With this configuration, the convex ring at the end of the sealing head can form a line contact seal with the sealing surface, achieving extremely high sealing specific pressure under relatively small clamping force, significantly improving the reliability of the seal, while reducing the driving force required by the electromagnet, which helps to reduce the size of the components and power consumption.

[0021] In one possible implementation, the cross-section of the convex ring is semi-circular or triangular.

[0022] By setting the cross-sectional shape of the convex ring to semi-circular, its smooth arc profile achieves good line or surface contact with the sealing surface, forming an effective seal under lower clamping force and with low frictional resistance, which helps extend the service life of the seal. When the convex ring has a triangular cross-section, its sharp edges can generate higher contact pressure under the same clamping force, thus forming a more reliable sealing barrier, especially suitable for fluid media containing small particles. Both shapes are simple in structure and easy to manufacture, balancing manufacturing cost and durability requirements while ensuring reliable sealing.

[0023] In one possible implementation, the razor cleaning device includes a water tank and a cleaning solution tank; wherein the water tank is used to store cleaning water and the cleaning solution tank is used to store cleaning solution; the water tank and the wastewater tank are located at the bottom of the housing and are arranged side by side on a horizontal plane along a first direction, and the cleaning chamber and the cleaning solution tank are spaced apart on a horizontal plane along a second direction, wherein the first direction is perpendicular to the second direction.

[0024] This design fully utilizes the space at the bottom of the casing, placing the heavier raw water tank and wastewater tank as a counterweight at the very bottom. This effectively lowers the center of gravity of the shaver cleaning device, improving its stability and safety. By arranging the cleaning chamber and cleaning fluid tank at intervals in the second direction, multiple tanks can be distributed in a cross pattern on the horizontal plane, avoiding the stacking of different fluid systems in the vertical direction. This optimizes the pipeline connection path, reduces fluid transport resistance, and achieves a high degree of functional integration within a limited space, contributing to the miniaturization of shaver cleaning devices.

[0025] In one possible implementation, the cleaning fluid tank is detachably mounted on the base.

[0026] This design allows users to easily remove the cleaning fluid tank from the base for independent replenishment or cleaning and maintenance of the tank's interior. This improves the convenience of changing the cleaning fluid and performing routine maintenance, avoiding cleaning dead spots and hygiene hazards caused by a fixed structure. Furthermore, the detachable modular design allows the cleaning fluid tank to be separated from the base as an independent unit, facilitating production assembly and subsequent maintenance.

[0027] In one possible implementation, a detection device is provided at the bottom of the cleaning fluid tank to detect whether there is cleaning fluid in the tank.

[0028] This design allows for direct and accurate monitoring of the liquid level in the cleaning fluid tank. When the cleaning fluid is insufficient or depleted, the device can promptly alert the user or automatically interrupt the cleaning process. This effectively prevents the shaver cleaning device from running dry or performing ineffective cleaning when there is no cleaning fluid, and avoids potential damage to critical components such as the pump and heater caused by dry burning or insufficient liquid operation. By placing the detection device at the bottom of the tank, it can detect the lowest liquid level to the greatest extent possible, ensuring timely and accurate detection.

[0029] In one possible implementation, the bottom of the cleaning fluid tank is provided with a pair of first electrical connections; the first electrical connections pass through the bottom of the cleaning fluid tank, and a portion of the structure is located inside the cleaning fluid tank. The portion of the first electrical connection located inside the cleaning fluid tank is configured as a probe end, and the portion of the first electrical connection located outside the cleaning fluid tank is configured as a connection end; a pair of second electrical connections are provided on the base, which match the positions of the first electrical connections; when the cleaning fluid tank is correctly installed in the base, the connection ends of the first electrical connections and the second electrical connections are electrically connected.

[0030] This configuration allows the first electrical connection part to perform both liquid level detection and electrical connection functions. The part of the first electrical connection part that extends into the tank directly serves as the detection electrode, and the liquid level is determined by detecting the conductivity between the electrodes. The part that extends out of the tank serves as the connection terminal. When the cleaning liquid tank is installed in place, the connection terminal automatically forms an electrical connection with the second electrical connection part on the base. This eliminates the need for the complex cable connection between the traditional liquid level sensor and the connector, thereby simplifying the structure, reducing the number of parts, and reducing the assembly difficulty.

[0031] In one possible implementation, the bottom of the cleaning fluid tank is provided with a positioning protrusion, and the base is provided with a positioning groove that mates with the positioning protrusion; when the cleaning fluid tank is correctly installed in the base, the positioning protrusion is located in the positioning groove.

[0032] By setting positioning protrusions and positioning grooves, the cleaning fluid tank can be prevented from shifting during installation, ensuring precise alignment between the first and second electrical connections, and preventing misinstallation.

[0033] A second aspect of this application provides a shaving system including a shaving razor and a shaving cleaning device as described in any of the first aspects. Attached Figure Description

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0060] To address the technical problems in the background art, this application provides a razor cleaning device. By providing a base on the housing and a specific flow channel on the base, the entire control valve structure can be integrated onto the base, making the entire razor cleaning device more compact. This solves the problem of the large space occupied by the valve body structure in related technologies, which hinders the miniaturization of razor cleaning devices.

[0061] The razor cleaning device and razor system provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0062] Figure 1 This is a schematic diagram of a razor system provided in an embodiment of this application. Figure 2 This is a cross-sectional structural diagram of a shaver system provided in an embodiment of this application. Figure 3 This is a cross-sectional structural diagram of a razor cleaning device provided in an embodiment of this application.

[0063] It should be noted that, for ease of description, in the embodiments of this application, the height direction of the shaver cleaning device is taken as the z-direction, the length direction of the shaver cleaning device is taken as the x-direction, and the width direction of the shaver cleaning device is taken as the y-direction.

[0064] like Figure 1As shown, this application embodiment provides a shaver system 1000, which may include a shaver cleaning device 100 and a shaver 200. The shaver cleaning device 100 is configured to clean, disinfect, and dry the shaver head 210 of the shaver 200, and to charge the shaver 200, etc.

[0065] like Figure 2 As shown, the razor 200 may include a razor head 210 and a handle 220. The razor head 210 may include a head housing 2101, a head foil 2102, and a blade holder (not shown). The head housing 2101 is used to connect the razor handle 220. The head foil 2102 is fixed to the head housing 2101 and forms a curved surface that contacts the skin during shaving. The head foil 2102 has micropores that allow hair to enter. The blade holder is rotatably disposed inside the head housing 2101 and located inside the head foil 2102. At least one blade (not shown) is mounted on the blade holder. During shaving, hair that enters the head foil 2102 is cut off by the blade on the rotating blade holder.

[0066] The specific structure of the shaver cleaning device 100 is described below with reference to the accompanying drawings.

[0067] This application provides a razor cleaning device 100, combined with... Figure 1 , Figure 2 and Figure 3 As shown, the shaver cleaning device 100 may include a housing 10, and a raw water tank 11, a cleaning solution tank 12, a cleaning chamber 131, and a wastewater tank 14 integrated within the housing 10. The raw water tank 11 stores cleaning water. The cleaning solution tank 12 stores cleaning solution. The cleaning chamber 131 has a top opening for receiving and cleaning the shaver head 210. The wastewater tank 14 collects wastewater generated after cleaning.

[0068] For example, see Figure 2 and Figure 3 As shown, the cleaning chamber 131 and the cleaning solution tank 12 are spaced apart along the length direction (x direction, i.e., the second direction) of the shaver cleaning device 100. The raw water tank 11 and the waste water tank 14 are arranged side by side along the width direction (y direction, i.e., the first direction) of the shaver cleaning device 100.

[0069] This allows for a more compact structure in the shaver cleaning device 100. By fully utilizing the space at the bottom of the housing 10, the heavier raw water tank 11 and wastewater tank 14 can be placed at the very bottom of the housing 10 as a counterweight, effectively lowering the center of gravity of the shaver cleaning device 100 and improving its stability and safety. By arranging the cleaning chamber 131 and cleaning liquid tank 12 at intervals in the x-direction, multiple tanks can be distributed in a cross pattern on the horizontal plane, avoiding the stacking of different fluid systems in the vertical direction. This optimizes the pipe connection path, reduces fluid transport resistance, and achieves a high degree of functional integration within a limited space, contributing to the miniaturization of the shaver cleaning device 100.

[0070] In this embodiment, the shaver cleaning device 100 may further include a fluid system (not shown) connecting the raw water tank 11, the cleaning fluid tank 12, the cleaning chamber 131, and the wastewater tank 14. This fluid system is configured to deliver water from the raw water tank 11 and cleaning fluid from the cleaning fluid tank 12 to the cleaning chamber 131 to clean the shaver head 210, and to deliver the wastewater generated after cleaning from the cleaning chamber 131 to the wastewater tank 14.

[0071] In some embodiments, the raw water tank 11, cleaning fluid tank 12, cleaning chamber 131, and wastewater tank 14 form a non-circulating unidirectional fluid path through a fluid circuit system. This ensures that during a single cleaning process, the liquid flows unidirectionally from the raw water tank 11 and cleaning fluid tank 12 to the wastewater tank 14, and is not reused.

[0072] Of course, in other embodiments, the raw water tank 11, cleaning liquid tank 12, cleaning chamber 131, and wastewater tank 14 can also form a bidirectional fluid path that can circulate through the liquid circuit system. In the embodiments of this application, the circulation mode of the liquid circuit system is not further limited.

[0073] In this embodiment, only the partial liquid path system from the raw water tank 11 and the cleaning liquid tank 12 to the cleaning chamber 131, and from the cleaning chamber 131 to the wastewater tank 14 is described.

[0074] See Figure 3 As shown, the cleaning chamber 131 may include a drain outlet 132, which is connected to the wastewater tank 14. The wastewater generated after cleaning is transported from the drain outlet 132 of the cleaning chamber 131 to the wastewater tank 14. Figure 3 The dashed arrows in the diagram represent the paths through which wastewater is discharged. Figure 3 The drain outlet 132 is in the open state.

[0075] In some embodiments, a drain valve 70 is provided at the drain outlet 132 of the cleaning chamber 131. This drain valve 70 is configured to seal the drain outlet 132 during the cleaning and mixing solution retention phase to ensure thorough cleaning and soaking. During the drainage phase, the drain outlet 132 is opened to quickly drain the wastewater.

[0076] By setting the drain valve 70, precise control of the drain outlet 132 of the cleaning chamber 131 can be achieved, ensuring that the cleaning chamber 131 can reliably store liquid during the cleaning and mixed solution retention stages, guaranteeing thorough cleaning and soaking. During the drainage stage, wastewater can be quickly drained, improving the automation and reliability of the entire cleaning process.

[0077] like Figure 4 As shown, the shaver cleaning device 100 may include a base 13, which is disposed within the housing 10. The base 13 has a groove that matches the shape of the cleaning chamber 131. The cleaning chamber 131 is detachably disposed within the base 13, with an opening at the top and a drain outlet 132 at the bottom, which is connected to a wastewater tank 14 via the base 13.

[0078] Combination Figure 4 and Figure 5 As shown, the base 13 has a flow channel 130 connecting the drain outlet 132 and the wastewater tank 14. The flow channel 130 may include a horizontal section 1301 extending in a horizontal direction, and an annular wall 1302 is provided within the horizontal section 1301. For example, the annular wall 1302 may be located within the horizontal section 1301 near the drain outlet 132. This provides reserved space for the installation of the drain valve 70.

[0079] Optionally, the central axis of the annular wall 1302 coincides with the axis of the horizontal section 1301, and the side of the annular wall 1302 away from the drain outlet 132 has a sealing surface 1303. A drain valve 70 is provided on the side of the sealing surface 1303 away from the drain outlet 132. The drain valve 70 may include a valve core 72 and a sealing head 73. The sealing head 73 is fixed to the end of the valve core 72, and the end of the valve core 72 with the sealing head 73 is positioned facing the sealing surface 1303. The valve core 72 can extend and retract horizontally within the horizontal section 1301. The valve core 72 is configured to drive the sealing head 73 to press against or disengage from the sealing surface 1303 of the annular wall 1302 during horizontal movement, thereby sealing or opening the flow passage 130.

[0080] The shaver cleaning device 100 in this embodiment of the application, by setting a detachable base 13 and a cleaning chamber 131, allows the user to easily disassemble the cleaning chamber 131, thereby cleaning the cleaning chamber 131, reducing the difficulty of cleaning the cleaning chamber 131, and ensuring that the cleaning chamber 131 is clean and tidy.

[0081] By providing a flow channel 130 connecting the drain outlet 132 and the wastewater tank 14 within the base 13, and designing a horizontal extension section in the key part of the flow channel 130, and setting the driving direction of the valve core 72 of the drain valve 70 to horizontal extension, the entire drain valve 70 can make full use of the horizontal space inside the housing 10, effectively avoiding the extra vertical height required by the traditional vertical arrangement of valves, thereby significantly compressing the vertical dimension of the housing 10, making the overall structure of the shaver cleaning device 100 more compact, which is conducive to the miniaturization of the shaver cleaning device 100.

[0082] By setting a horizontal section 1301 coaxially with an annular wall 1302 to form a sealing surface 1303 in the horizontally extended flow channel 130, and cooperating with the valve core 72 to drive the sealing head 73 to press the sealing surface 1303, the axial sealing of the flow channel 130 is achieved. This allows the sealing head 73 to uniformly bear the linear thrust from the valve core 72 when closed, thereby effectively avoiding the problems of uneven wear and poor sealing caused by lateral force. Moreover, the cooperation between the annular sealing surface 1303 and the sealing head 73 forms a large-area contact seal, which significantly improves the reliability and durability of the seal and effectively prevents liquid leakage.

[0083] See also Figure 5 As shown, the flow channel 130 may include a first vertical section 1304 and a second vertical section 1305. One end of the first vertical section 1304 is connected to the drain outlet 132, and the other end is connected to the horizontal section 1301. One end of the second vertical section 1305 is connected to the horizontal section 1301, and the other end is connected to the wastewater tank 14. A portion of the structure of the annular wall 1302 forms the inner wall of the second vertical section 1305.

[0084] It should be noted that the extension direction of the first vertical segment 1304 and the second vertical segment 1305 is approximately the vertical direction (z direction). Specifically, it can be parallel to the vertical direction (z direction) or set at a certain angle to the vertical direction (z direction). In the embodiments of this application, the extension direction of the first vertical segment 1304 and the second vertical segment 1305 is not further limited.

[0085] This configuration allows a portion of the annular wall 1302 to directly form the inner wall of the second vertical section 1305, enabling the sealing surface 1303 and the second vertical section 1305 to be integrally formed. This reduces the number of independent sealing parts, lowers assembly difficulty and production costs, and eliminates the risk of leakage that may result from assembly gaps between parts, greatly improving the sealing reliability of the flow channel 130.

[0086] See also Figure 5As shown, a smoothly transitioning bend 1306 is formed between the first vertical segment 1304 and the horizontal segment 1301. Exemplarily, this bend 1306 can be an arc-shaped wall structure. In this embodiment, the curvature of this arc-shaped wall structure is not further limited.

[0087] This design eliminates the sharp edges of traditional right-angle turns through the bend 1306, making the flow path smoother when the fluid changes from vertical to horizontal, effectively reducing flow resistance, improving wastewater discharge efficiency, helping to achieve rapid and thorough emptying, reducing sanitary dead corners, and avoiding dirt residue and channel blockage.

[0088] See Figure 6 As shown, the horizontal section 1301 has an extension wall 1307 extending away from the drain outlet 132 at one end. The extension wall 1307 forms a mounting cavity 137 with at least one opening, and the drain valve 70 is disposed in the mounting cavity 137 and fixedly connected to the extension wall 1307.

[0089] For example, the extension wall 1307 has openings on both sides, one side being located on the side opposite the sealing surface 1303 in the horizontal direction, and the other side being located on one side of the horizontal section 1301 in the circumferential direction. By providing openings on both sides, the drain valve 70 can be easily installed in the receiving cavity, reducing assembly difficulty.

[0090] This configuration allows the drain valve 70 to be compactly housed within the extended structure of the flow channel 130, eliminating the need for additional installation space within the base 13. This significantly optimizes the utilization of the internal space of the base 13, resulting in a more compact device structure and a more rational layout.

[0091] like Figure 6 As shown, the drain valve 70 includes an electromagnet 71. The valve core 72 is configured as a metal rod, which is driven by the electromagnet 71, which drives the metal rod to extend and retract horizontally. A sealing head 73 is fixed to the end of the metal rod.

[0092] When the electromagnet 71 is de-energized, the sealing head 73 is configured to press the sealing surface 1303 to seal the drain outlet 132. When the electromagnet 71 is energized, the magnetic force generated by the electromagnet 71 drives the metal rod to move the sealing head 73 away from the sealing surface 1303 to open the drain outlet 132.

[0093] By using an electromagnet 71 to drive the valve core 72 to move axially, the sealing head 73 is driven to automatically seal and open the drain outlet 132. Utilizing the magnetic force generated by the energized electromagnet 71 as the power source, the action is rapid and the control is precise. When the electromagnet 71 is de-energized, the sealing head 73 automatically seals the drain outlet 132 by gravity or a reset structure after the magnetic force disappears, forming a normally closed state and effectively preventing wastewater leakage. When drainage is needed, the drain outlet 132 can be quickly opened by energizing the electromagnet 71 via an electrical signal. The entire process requires no manual operation from the user, thus avoiding the hygiene risks of hand contact with sewage. Furthermore, it automates and intelligently integrates the drainage process, significantly improving the hygiene level and ease of use of the equipment.

[0094] like Figure 5 As shown, when the electromagnet 71 is energized, the magnetic force generated by the electromagnet 71 drives the valve core 72 to move the sealing head 73 away from the drain outlet 132, thereby opening the drain outlet 132.

[0095] like Figure 7 As shown, when the electromagnet 71 is de-energized, the sealing head 73 is configured to seal the drain outlet 132. For example, the sealing head 73 is press-fitted with the sealing surface 1303 of the annular wall to achieve a reliable seal. This "power-off safe" design prevents liquid leakage in the event of an accidental power outage.

[0096] The drain valve driven by electromagnet 71 has the advantages of fast response and precise control. Therefore, this setting enables rapid opening and closing, which is beneficial for the accurate execution of automated cleaning programs. Its power-off safety design, which seals when powered off and opens when powered on, can maintain the seal of the cleaning chamber 131 in the event of an accidental power failure, preventing liquid leakage and improving the safety and reliability of the product.

[0097] In one possible implementation, such as Figure 8 As shown, a raised ring 74 is provided at the end of the sealing head 73 that contacts the sealing surface 1303. The raised ring 74 is used to form a line contact seal with the sealing surface 1303.

[0098] In this way, the convex ring 74 provided at the end of the sealing head 73 can form a line contact seal with the sealing surface 1303, achieving extremely high sealing specific pressure under relatively small clamping force, significantly improving the reliability of the seal, while reducing the driving force required for the electromagnet 71, which helps to reduce the size of the components and power consumption.

[0099] For example, the cross-sectional shape of the convex ring 74 can be semi-circular or triangular, so that the outer surface of the convex ring 74 is hemispherical or conical.

[0100] By setting the cross-sectional shape of the convex ring 74 to semi-circular, its smooth arc profile achieves good line or surface contact with the sealing surface, forming an effective seal under lower clamping force and with low frictional resistance, which helps extend the service life of the seal. When the cross-section of the convex ring 74 is triangular, its sharp edges can generate higher contact pressure under the same clamping force, thus forming a more reliable sealing barrier, especially suitable for fluid media containing small particles. Both shapes are simple in structure and easy to manufacture, ensuring reliable sealing while balancing manufacturing cost and durability requirements.

[0101] Of course, in other embodiments, the cross-section of the convex ring 74 may be of other shapes. In this embodiment, the cross-sectional shape of the convex ring 74 is not further limited.

[0102] To detect the liquid levels in the raw water tank 11 and the cleaning solution tank 12, a detection device can be installed in the cleaning solution tank 12. The presence of water in the raw water tank 11 is determined by the operating time of the inlet pump. The detection device also detects the presence of cleaning solution in the cleaning solution tank 12. The detection device in the cleaning solution tank 12 is described below with reference to the accompanying drawings.

[0103] like Figure 9 and Figure 10 As shown, a detection device 60 is provided at the bottom of the cleaning fluid tank 12. The detection device 60 is used to detect whether there is cleaning fluid in the cleaning fluid tank 12.

[0104] By directly installing a detection device 60 at the bottom of the cleaning fluid tank 12, the system can directly and sensitively detect whether the cleaning fluid is depleted, providing a low-level warning and ensuring that users can replenish the cleaning fluid in a timely manner. Furthermore, this design facilitates assembly, simplifies the structure of the detection device 60, and consequently reduces costs.

[0105] For example, the detection device 60 may include two water level probes, the probe ends of which are located at the bottom of the cleaning fluid tank 12, for more direct detection of the remaining cleaning fluid and to achieve low liquid level warning.

[0106] For example, such as Figure 11 As shown, the cleaning fluid tank 12 is detachably connected to the housing 10, specifically, the cleaning fluid tank 12 is detachably mounted on the base 13. The bottom of the cleaning fluid tank 12 has a pair of first electrical connection portions 121 (e.g., two metal contacts or probe receiving ends), wherein the first electrical connection portions 121 pass through the bottom of the cleaning fluid tank 12, so that a portion of the structure is located inside the cleaning fluid tank 12. The portion located inside the cleaning fluid tank 12 is configured as a probe end, and the portion located outside the cleaning fluid tank 12 is configured as a connection end.

[0107] Accordingly, a pair of second electrical connections 15 (e.g., two elastic metal pins or spring pins) are provided on the base 13 to match the position of the first electrical connection 121.

[0108] When the cleaning fluid tank 12 is correctly installed in the housing 10, the connecting end of the first electrical connection part 121 and the second electrical connection part 15 are electrically connected, together forming the detection device 60 (i.e., the liquid level probe). The detection end of the first electrical connection part 121 (i.e., the part inside the cleaning fluid tank 12 that is in contact with the liquid) is located at the bottom of the cleaning fluid tank 12 through the opening at the bottom of the tank or the bottom of the tank itself, which is made of conductive material, and is used to detect whether there is still cleaning fluid in the tank.

[0109] This configuration allows the first electrical connection part 121 to perform both liquid level detection and electrical connection functions. The part of the first electrical connection part 121 that extends into the tank directly serves as a detection electrode, and the liquid level is determined by detecting the conductivity between the electrodes. The part that extends out of the tank serves as a connection terminal. When the cleaning liquid tank is installed in place, the connection terminal automatically forms an electrical connection with the second electrical connection part 15 on the base. This eliminates the need for complex cable connections between traditional liquid level sensors and connectors, thereby simplifying the structure, reducing the number of parts, and reducing assembly difficulty.

[0110] Furthermore, to ensure accurate alignment of the electrical connections, the bottom of the cleaning fluid tank 12 is provided with a positioning protrusion 122, and the base 13 is provided with a corresponding positioning groove 16. This convex-concave mating structure prevents the cleaning fluid tank 12 from shifting during installation, ensuring precise alignment of the first electrical connection 121 and the second electrical connection 15, while also preventing misinstallation.

[0111] For example, a sealing structure (not shown) can be provided between the outlet of the cleaning fluid tank 12 (not shown in the figure) and the flow channel interface of the base 13. When the cleaning fluid tank 12 is installed in place, the sealing structure seals the outlet of the cleaning fluid tank 12 and the flow channel interface of the base 13, thereby achieving a sealed connection of the fluid circuit and preventing cleaning fluid leakage.

[0112] For example, the shaver cleaning device 100 may include a control unit (not shown in the figure), which is electrically connected to the detection device 60. When the liquid level in the cleaning fluid tank 12 is higher than the detection end at the bottom of the cleaning fluid tank 12, the circuit between the control unit and the detection device 60 is connected, and the control unit determines that "cleaning fluid is available". When the liquid level drops below the detection end, the circuit between the control unit and the detection device 60 is disconnected, and the control unit determines that "cleaning fluid is insufficient". At this time, a low liquid level warning can be issued to the user through an audible and visual alarm (such as a flashing LED indicator or a buzzer), prompting the user to add or replace the cleaning fluid in time.

[0113] Of course, in other embodiments, the detection device 60 may also be a float switch, a Hall sensor, a gravity sensor, or other similar structures. In this embodiment, the specific structure of the detection device 60 is not further limited.

[0114] In one possible implementation, a wastewater detection device (not shown in the figure) can be installed inside the wastewater tank 14 to detect the liquid level inside the wastewater tank 14. An indicator light (not shown in the figure) can be installed on the housing of the shaver cleaning device 100. The wastewater detection device is signal-connected or electrically connected to the indicator light. When the wastewater detection device detects that the liquid level in the wastewater tank 14 has reached a preset height (for example, when the wastewater is about to fill), the indicator light emits a warning signal to remind the user to clean it in time, effectively preventing wastewater overflow.

[0115] It should be noted that, in this embodiment of the application, the specific value of the preset height is not further limited, and can be set according to the capacity of the wastewater tank 14.

[0116] By installing a wastewater detection device to monitor the liquid level in wastewater tank 14, an indicator light can remind users to clean it in time when the wastewater is about to be full, effectively preventing hygiene problems and equipment failures caused by wastewater overflow and improving the user experience.

[0117] For example, the wastewater detection device can be a water level detection needle installed inside the wastewater tank 14. By using a water level detection needle as the wastewater detection device, the structure of the wastewater detection device can be simplified, thereby reducing costs.

[0118] Of course, in other embodiments, the wastewater detection device may also be any one of an optical water level sensor or a capacitive water level sensor. In this embodiment, the specific structure of the wastewater detection device is not further limited.

[0119] In some embodiments, combined with Figure 9 and Figure 12 As shown, the cleaning chamber 131 is equipped with a water level sensor 133, a water inlet 138, and a drain outlet 132. The liquid circuit system may include a water inlet pump (not shown in the figure) connected to the water inlet 138. The water level sensor 133 is signal-connected or electrically connected to the water inlet pump. The water level sensor 133 is configured to control the water inlet pump to stop working when it detects that the liquid level in the cleaning chamber 131 has reached a preset height, thereby realizing automatic control of the liquid level and ensuring a constant water injection volume.

[0120] By monitoring the liquid level in the cleaning chamber 131 in real time through the water level sensor 133 and controlling the start and stop of the water pump, the liquid level in the cleaning chamber 131 can be automatically controlled, ensuring that the water injection volume for each cleaning is constant and reliable, avoiding too much or too little water injection, optimizing the cleaning process and saving resources.

[0121] It should be noted that, in this embodiment of the application, the water level sensor 133 installed in the cleaning chamber 131 can also be replaced with other liquid level detection devices, such as a probe or similar structure.
