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, common shaver cleaning devices typically include a water tank, a cleaning solution tank, and a cleaning basin, connected by tubing. During shaver cleaning, water from the water tank and cleaning solution from the cleaning solution tank are respectively introduced into the cleaning basin through two tubing lines. The water and cleaning solution form a mixture in the cleaning basin to clean the shaver located within. Typically, detection probes are installed in the water tank and the cleaning solution tank to monitor their levels.

[0004] However, if the detection probe malfunctions, the entire water tank or cleaning fluid tank needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0005] This application provides a razor cleaning device and razor system to solve the problem in the above-mentioned related technologies that when the detection probe malfunctions, the entire water tank or cleaning solution tank needs to be replaced, resulting in high maintenance costs.

[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 shaver cleaning device, including a water tank, a cleaning solution tank, a cleaning chamber, and a liquid path system. The liquid path system is connected to the water tank, the cleaning solution tank, and the cleaning chamber, and is used to transport liquid from the water tank and the cleaning solution tank to the cleaning chamber. A flow passage includes a detection device and a flow cavity, with a portion of the detection device located within the flow cavity, and the detection device is used to detect whether liquid is passing through the flow passage. One of the two flow passages is disposed between the water tank and the cleaning chamber, and the other of the two flow passages is disposed between the cleaning solution tank and the cleaning chamber.

[0008] The razor cleaning device provided in this embodiment achieves independent monitoring of the flow status of raw water and cleaning fluid before they enter the mixing unit by independently installing flow components with detection devices between the raw water tank and the cleaning chamber, and between the cleaning fluid tank and the cleaning chamber. This distributed detection layout can accurately identify any interruption, blockage, or supply abnormality of any liquid in the raw water tank or cleaning fluid tank during the transportation process, thereby triggering early warning or protection actions before the liquid enters the mixing chamber, effectively avoiding the generation of ineffective mixture due to the lack of a single raw material. This further improves the comprehensiveness and reliability of the liquid system status monitoring.

[0009] By setting up independent flow components and integrating detection devices, the liquid level detection function can be modularized. This way, when the detection device malfunctions and requires maintenance, only the flow components need to be replaced, without having to replace the entire raw water tank and cleaning fluid tank, thereby reducing maintenance costs.

[0010] In one possible implementation, the flow passage includes an inlet and an outlet; the flow passage cavity is provided with an inclined wall; wherein the inclination direction of the inclined wall is configured such that the cross-sectional area of ​​the flow passage cavity gradually increases from the inlet to the outlet.

[0011] Liquids (especially water) tend to form a strong, adhesive "water film" when flowing over a surface. This inclined wall structure effectively disturbs and disrupts the continuous water film formed on the sensing surface of the detection device, preventing the water film from distorting the detection signal (such as misinterpreting intermittent water flow as continuous liquid). This ensures that the detection device can respond quickly and accurately when liquid flows in, greatly improving the sensitivity and reliability of liquid level detection.

[0012] Furthermore, the inclined wall naturally slows down the flow rate of the liquid after it flows in, guiding it smoothly and steadily towards the outlet. This avoids the direct impact of high-speed liquid flow on the detection device and the resulting signal fluctuations. It ensures that the liquid can uniformly and fully cover the detection area, providing a stable and ideal detection environment for the device, thereby improving the accuracy and reliability of liquid level detection.

[0013] In one possible implementation, a baffle wall is provided inside the flow cavity; wherein the baffle wall is provided at the end of the liquid outlet facing the flow cavity, and the end of the baffle wall facing the inclined wall is provided with an opening so that the liquid outlet communicates with the flow cavity through the opening.

[0014] This design allows the baffle wall to further guide and stabilize the liquid flow, preventing the liquid from directly impacting the outlet and ensuring the stability of the liquid surface in the detection area. At the same time, the opening design ensures the smooth outflow of the liquid, further optimizing the detection environment and improving detection accuracy.

[0015] In one possible implementation, the flow chamber includes a top wall and a bottom wall opposite each other in a vertical direction, the bottom wall being configured as an inclined wall; the detection device includes two water level probes; the two water level probes are spaced apart along the direction of liquid flow in the flow chamber; one of the two water level probes is located on the top wall, and the other of the two water level probes is located on the bottom wall.

[0016] By placing two water level probes on the top and bottom walls of the flow cavity respectively and arranging them at intervals along the direction of liquid flow, the inherent space of the flow cavity in the vertical direction is fully utilized. This allows the water level probes to overlap in the projection area perpendicular to the flow direction, thereby achieving dual-point detection within a limited space. This avoids the increase in the volume of the liquid circuit system caused by lateral expansion and effectively improves the structural integration.

[0017] In one possible implementation, the orthographic projections of the two water level probes in a first plane at least partially overlap; wherein the first plane is perpendicular to the direction of liquid flow within the flow cavity.

[0018] By ensuring that the orthographic projections of the two water level probes on a plane perpendicular to the direction of liquid flow at least partially overlap, the detection areas can be partially overlapped in space. This ensures that when liquid flows through the flow cavity, it can simultaneously cover the effective detection areas of both probes, avoiding detection blind spots caused by liquid flow direction deviation or uneven flow field distribution, thereby improving the accuracy of the detection device.

[0019] In one possible implementation, in the vertical direction, the end of the water level probe located on the bottom wall inside the flow cavity is higher than the end of the outlet near the bottom wall; in the vertical direction, the end of the water level probe located on the top wall inside the flow cavity is flush with the end of the outlet near the bottom wall.

[0020] By setting the water level probe located on the bottom wall higher than the bottom of the liquid outlet, a certain liquid level can always be maintained in the flow chamber, ensuring continuous contact between the water level probe and the liquid, guaranteeing continuous detection, preventing frequent switching of the detection signal due to liquid draining, and thus improving detection stability.

[0021] By positioning the water level probe on the top wall flush with the bottom of the outlet, the probe is only triggered when liquid can flow out. This design accurately determines whether the liquid has reached a flowable state, effectively identifying abnormal liquid levels caused by insufficient flow or air resistance, and avoiding false detections caused by localized liquid level fluctuations.

[0022] In one possible implementation, the liquid system includes a transfer station, which includes a first inlet connected to the raw water tank, a second inlet connected to the cleaning liquid tank, and an outlet connected to the cleaning chamber.

[0023] One of the two flow-through components is located between the raw water tank and the first inlet, and the other of the two flow-through components is located between the cleaning liquid tank and the second inlet.

[0024] By setting up a transfer station, the cleaning solution in the cleaning solution tank and the clean water in the raw water tank can be pre-mixed to form a uniform mixed solution before being uniformly transported to the cleaning chamber. This can avoid the problem of uneven mixing between the raw water and the cleaning solution in the cleaning chamber and ensure the stability of the cleaning effect.

[0025] In one possible implementation, the liquid circuit system includes a first pipeline, a second pipeline, and a third pipeline; wherein the first pipeline is used to connect the raw water tank to a flow passage located between the raw water tank and the first inlet; the second pipeline is used to connect the cleaning liquid tank to a flow passage located between the cleaning liquid tank and the second inlet; and the third pipeline is used to connect the outlet of the transfer station to the cleaning chamber; the inner diameter of the first pipeline is larger than the inner diameter of the second pipeline, so that the flow rate of water flowing from the raw water tank to the transfer station is greater than the flow rate of cleaning liquid flowing from the cleaning liquid tank to the transfer station, thereby forming a predetermined proportion of mixed solution in the transfer station.

[0026] By differentiating the inner diameters of the first and second pipelines and utilizing fluid dynamics principles, water and cleaning fluid can flow to the transfer station at different stable flow rates under the same or similar driving pressure. This achieves the effect of automatically controlling the mixing ratio without complex electronic control components, simplifying the structure of the liquid circuit system and thus reducing costs.

[0027] In one possible implementation, the ratio of the inner diameter of the first pipe to the inner diameter of the second pipe is 5-7.

[0028] By limiting the ratio of the inner diameter of the first pipe to the inner diameter of the second pipe to a range of 5-7, the mixing ratio of cleaning solution and water can be optimized within a suitable range, ensuring that the cleaning solution has a sufficient concentration to effectively dissolve oil stains and disinfect. This also avoids waste and residue caused by excessive use of cleaning solution.

[0029] In one possible implementation, the inner diameter of the first pipe is 3 mm; the inner diameter of the second pipe is 0.5 mm.

[0030] This configuration ensures that the first and second pipelines obtain appropriate fluid flow rates under normal pump drive pressure, avoiding problems such as excessive flow resistance and easy blockage caused by too small pipe diameter, and also avoiding problems such as inaccurate mixing ratio control and increased equipment size caused by too large pipe diameter.

[0031] In one possible implementation, the transfer station is equipped with a mixing chamber; wherein the first inlet, the second inlet and the outlet are all connected to the mixing chamber; the first inlet and the second inlet are respectively connected to the liquid outlets of two flow-through components, and the outlet is connected to the cleaning chamber. The mixing chamber is configured to mix the water in the raw water tank and the cleaning liquid in the cleaning liquid tank into a mixed solution before transporting it to the cleaning chamber.

[0032] This configuration allows the raw water and cleaning solution to be transported to the mixing chamber through two separate flow channels, where they are fully pre-mixed to form a uniform solution before being uniformly transported to the cleaning chamber. This avoids the problem of uneven mixing that may occur between the raw water and cleaning solution in the cleaning chamber, ensuring the stability of the cleaning effect.

[0033] In one possible implementation, the mixing chamber is S-shaped; in the direction of liquid flow within the mixing chamber, the first inlet and the second inlet are located at one end of the mixing chamber, and the outlet is located at the other end of the mixing chamber.

[0034] This design, with its S-shaped mixing chamber structure, extends the fluid flow path, increases the turbulence and contact time of water and cleaning fluid within the chamber, thereby promoting thorough and uniform mixing and helping to improve the quality of the mixed solution and the stability of the cleaning effect.

[0035] In one possible implementation, the transfer station includes an end cap and a base; wherein the base has a groove structure and the end cap has a protruding sealing part; when the end cap covers the side of the base with the groove structure, the sealing part is sealed within the groove structure, and a mixing cavity is formed between the sealing part and the groove structure.

[0036] This application embodiment adopts a split structure design of end cap and base, with grooves on the base and sealing parts on the end cap to cooperate with them, so that when the base and end cap are assembled, a sealed mixing cavity can be naturally formed. This simplifies the processing and assembly process of the mixing cavity, and avoids leakage problems that may occur when multiple parts are spliced ​​through the one-piece molded sealing structure.

[0037] In one possible implementation, the transfer station is a three-way structure. This design simplifies the transfer station's structure and thus reduces costs.

[0038] 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

[0071] 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.

[0072] To address the technical problem of uneven concentration of the mixed solution of clean water and cleaning fluid in the cleaning tank, resulting in poor cleaning effect, this application provides a shaver cleaning device. By setting an independent flow-through component with a detection device in the liquid circuit system, the liquid level detection function can be modularized. In this way, when maintenance is required later, only the flow-through component needs to be replaced, without replacing the entire raw water tank and cleaning fluid tank, thereby reducing maintenance costs.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] like Figure 1 As 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.

[0077] like Figure 2As 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.

[0078] The specific structure of the shaver cleaning device 100 is described below with reference to the accompanying drawings.

[0079] 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.

[0080] 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) 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) of the shaver cleaning device 100. This allows the structure of the shaver cleaning device 100 to be more compact.

[0081] In this embodiment, the shaver cleaning device 100 may further include a fluid system connecting the raw water tank 11, the cleaning solution 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 solution from the cleaning solution 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.

[0082] 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 liquid 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, without being reused. Of course, in other embodiments, the raw water tank 11, cleaning fluid tank 12, cleaning chamber 131, and wastewater tank 14 can also form a circulating bidirectional fluid path through the liquid circuit system. In the embodiments of this application, the circulation method of the liquid circuit system is not further limited.

[0083] 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.

[0084] 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.

[0085] In some embodiments, a drain valve assembly 70 is provided at the drain outlet 132 of the cleaning chamber 131. This drain valve assembly 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.

[0086] By incorporating the drain valve assembly 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 discharged, improving the automation and reliability of the entire cleaning process.

[0087] Figure 4 An exploded view of the base of a razor cleaning device provided in an embodiment of this application; Figure 5 This is an exploded structural diagram of a drain valve assembly of a razor cleaning device provided in an embodiment of this application. Figure 6 This is a cross-sectional structural diagram of a razor cleaning device with its drain outlet open, provided as an embodiment of this application.

[0088] 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 disposed within the base 13, with an opening at the top and a drain outlet 132 at the bottom, which is connected to the wastewater tank 14 through the base 13.

[0089] For example, a mounting cavity 137 for mounting the drain valve assembly 70 is formed on the base 13. One end of the mounting cavity 137 is connected to the drain port 132 of the cleaning chamber 131. Part of the outer wall of the mounting cavity 137 can provide a certain support for the drain valve assembly 70 to increase the stability of the drain valve assembly 70.

[0090] For example, such as Figure 5 As shown, the drain valve assembly 70 can be an electromagnetically driven drain valve, which may include an electromagnet 71, a metal rod 72 driven and connected to the electromagnet 71, and a sealing sleeve 73 fixed to the end of the metal rod 72.

[0091] like Figure 3 As shown, when the electromagnet 71 is de-energized, the sealing sleeve 73 is configured to seal the drain outlet 132. Exemplarily, the sealing sleeve 73 is interference-fitted with the sidewall at the drain outlet 132 to achieve a reliable seal. This "power-off safe" design prevents liquid leakage in the event of an accidental power outage. Figure 6 As shown, when the electromagnet 71 is energized, the magnetic force generated by the electromagnet 71 drives the metal rod 72 to move the sealing sleeve 73 away from the drain outlet 132, thereby opening the drain outlet 132.

[0092] 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.

[0093] In one possible implementation, such as Figure 7 As shown, the end of the sealing sleeve 73 that contacts the drain outlet 132 is provided with a protruding ring 74. The protruding ring 74 is used to form a line contact seal with the inner wall of the drain outlet 132.

[0094] In this way, the convex ring 74 at the end of the sealing sleeve 73 can form a line contact seal with the inner wall of the drain outlet 132, 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.

[0095] 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. Of course, in other embodiments, the cross-sectional shape of the convex ring 74 can also be other shapes. In this embodiment, the cross-sectional shape of the convex ring 74 is not further limited.

[0096] In one possible implementation, such as Figure 8 and Figure 9 As shown, the liquid circuit system may include a transfer station 21 and two flow passages 50. The transfer station 21 may include a first inlet 211 connected to the raw water tank 11, a second inlet 212 connected to the cleaning liquid tank 12, and an outlet 213 connected to the cleaning chamber 131.

[0097] It should be noted that the first inlet 211 and the flow passage 50, as well as the second inlet 212 and the flow passage 50, can be connected by hoses or the like.

[0098] In this embodiment, the flow element 50 may include a detection device 40 and a flow cavity 53. Part of the structure of the detection device 40 is located in the flow cavity 53. The detection device 40 is used to detect whether liquid flows through the flow element 50. One of the two flow elements 50 is disposed between the raw water tank 11 and the first inlet 211, and the other of the two flow elements 50 is disposed between the cleaning liquid tank 12 and the second inlet 212.

[0099] The razor cleaning device 100 provided in this embodiment achieves independent monitoring of the flow status of raw water and cleaning liquid before they enter the mixing unit by independently installing flow elements 50 with detection devices 40 between the raw water tank 11 and the first inlet 211, and between the cleaning liquid tank 12 and the second inlet 212. This distributed detection layout can accurately identify any interruption, blockage, or supply abnormality of any liquid in the raw water tank 11 or the cleaning liquid tank 12 during the transportation process, thereby triggering early warning or protection actions before the liquid enters the mixing chamber, effectively avoiding the generation of invalid mixed liquid due to the lack of a single raw material. This further improves the comprehensiveness and reliability of the liquid circuit system status monitoring.

[0100] By setting up an independent flow-through component 50 and integrating the detection device 40, the liquid level detection function can be modularized. In this way, when the detection device 40 malfunctions and needs maintenance, only the flow-through component 50 can be replaced, without replacing the entire raw water tank 11 and cleaning liquid tank 12, thereby reducing maintenance costs.

[0101] To achieve a stable mixing ratio, the liquid system may include a first pipe 22, a second pipe 23, and a third pipe 24. The first pipe 22 connects the raw water tank 11 to the flow-through component 50 located between the raw water tank 11 and the first inlet 211. The second pipe 23 connects the cleaning liquid tank 12 to the flow-through component 50 located between the cleaning liquid tank 12 and the second inlet 212. The outlet 213 of the transfer station 21 and the cleaning chamber 131 are connected via the third pipe 24.

[0102] For example, the inner diameter of the first pipe 22 is larger than the inner diameter of the second pipe 23. Utilizing the principles of fluid mechanics, under the same or similar driving pressure, the flow rate of water flowing from the raw water tank 11 to the transfer station 21 is greater than the flow rate of cleaning liquid flowing from the cleaning liquid tank 12 to the transfer station 21, thereby automatically forming a mixed solution of a predetermined ratio in the transfer station 21.

[0103] By differentiating the inner diameters of the first pipe 22 and the second pipe 23, and utilizing the principles of fluid mechanics, water and cleaning fluid are directed to the transfer station 21 at different stable flow rates under the same or similar driving pressure. This achieves the effect of automatically controlling the mixing ratio without complex electronic control components, simplifying the structure of the liquid circuit system and thus reducing costs.

[0104] In some embodiments, the ratio of the inner diameter of the first pipe 22 to the inner diameter of the second pipe 23 can be 5-7. For example, the ratio of the inner diameter of the first pipe 22 to the inner diameter of the second pipe 23 is 5, 6, or 7. In the embodiments of this application, the ratio of the inner diameter of the first pipe 22 to the inner diameter of the second pipe 23 is not further limited.

[0105] By limiting the ratio of the inner diameter of the first pipe 22 to that of the second pipe 23 to a range of 5-7, the mixing ratio of cleaning solution and water can be optimized within a suitable range, ensuring that the cleaning solution has a sufficient concentration to effectively dissolve oil stains and disinfect. This also avoids waste and residue caused by excessive use of cleaning solution.

[0106] In one possible implementation, the inner diameter of the first conduit 22 can be 3 mm, and the inner diameter of the second conduit 23 can be 0.5 mm. In this case, the ratio of the inner diameter of the first conduit 22 to the inner diameter of the second conduit 23 is 6.

[0107] By setting the inner diameter of the first pipe 22 to 3mm and the inner diameter of the second pipe 23 to 0.5mm, it is possible to ensure that the first pipe 22 and the second pipe 23 obtain appropriate fluid flow under the normal water pump drive pressure. This avoids the problems of excessive flow resistance and easy blockage caused by too small a pipe diameter, and also avoids the problems of inaccurate mixing ratio control and increased equipment size caused by too large a pipe diameter.

[0108] like Figure 8 and Figure 9 As shown, the transfer station 21 in the liquid system is a three-way structure, which includes a first inlet 211 connected to the raw water tank 11, a second inlet 212 connected to the cleaning liquid tank 12, and an outlet 213 connected to the cleaning chamber 131. The water entering from the first inlet 211 and the cleaning liquid entering from the second inlet 212 can mix at the outlet 213 and be output to the cleaning chamber 131.

[0109] In this embodiment, the liquid circuit system may include two independent flow elements 50. One of the two flow elements 50 is disposed between the raw water tank 11 and the first inlet 211 of the transfer station 21, and the other of the two flow elements 50 is disposed between the cleaning liquid tank 12 and the second inlet 212 of the transfer station 21. Each flow element 50 is provided with a detection device 40.

[0110] The structure of the flow element 50 will be described in detail below with reference to the accompanying drawings.

[0111] like Figure 9 and Figure 10 As shown, each flow element 50 includes an inlet 51, an outlet 52, and a flow cavity 53 located between the inlet 51 and the outlet 52. Each flow element 50 is equipped with a detection device 40, and a portion of the structure of the detection device 40 is located within the flow cavity 53. For example, the probe end of the detection device 40 is located within the flow cavity 53. That is, the probe end of the water level detection needle is located within the flow cavity 53.

[0112] By setting up an independent flow-through component 50 and integrating a detection device 40, the liquid level detection function can be modularized, so that the implementation of this function does not depend on specific structures such as the transfer station 21, thereby improving the flexibility and versatility of the liquid circuit system design.

[0113] See Figure 10 As shown, the flow cavity 53 is provided with an inclined wall 54, and the inclined direction of the inclined wall 54 is configured from the liquid inlet 51 to the liquid outlet 52, and the cross-sectional area of ​​the flow cavity 53 gradually increases.

[0114] It should be noted that liquids (especially water) tend to form a strong, adhesive "water film" when flowing over a surface. The inclined wall 54 structure effectively disturbs and disrupts the continuous water film formed on the sensing surface of the detection device, preventing signal distortion caused by the water film (such as misinterpreting intermittent water flow as continuous liquid). This ensures that the detection device can respond quickly and accurately when liquid flows in, greatly improving the sensitivity and reliability of liquid level detection.

[0115] Furthermore, the inclined wall 54 naturally slows down the flow rate of the liquid after it flows in, guiding the liquid to flow smoothly and steadily towards the outlet 52. This avoids the direct impact of high-speed liquid flow on the detection device and the resulting signal fluctuations. It ensures that the liquid can uniformly and fully cover the detection area, providing a stable and ideal detection environment for the detection device, thereby improving the accuracy and reliability of liquid level detection.

[0116] For example, the flow cavity 53 may include a top wall 56 and a bottom wall 57 opposite each other in the vertical direction (z direction), and the bottom wall 57 is configured as an inclined wall 54. In other words, the inclined wall 54 is formed on the bottom wall 57.

[0117] In this embodiment, the detection device 40 may include two water level probes, which are spaced apart along the direction of liquid flow within the flow cavity 53. One of the two water level probes is located on the top wall 56, and the other is located on the bottom wall 57.

[0118] For example, one of the two water level probes passes through the outside of the bottom wall 57, and a portion of the structure of the water level probe is located within the flow cavity 53. The other of the two water level probes passes through the top wall 56, and a portion of the structure of the water level probe is located within the flow cavity 53.

[0119] By placing two water level probes on the top wall 56 and bottom wall 57 of the flow cavity 53 respectively and arranging them at intervals along the liquid flow direction, the inherent space of the flow cavity 53 in the vertical direction (z direction) is fully utilized, so that the water level probes can be arranged in an overlapping manner in the projection area perpendicular to the flow direction. This achieves dual-point detection function in a limited space, avoids the increase in the volume of the liquid circuit system due to lateral expansion, and effectively improves the structural integration.

[0120] See Figure 10 As shown, the orthographic projections of the two water level probes in the first plane at least partially overlap. The first plane is perpendicular to the direction of liquid flow within the flow cavity 53.

[0121] By ensuring that the orthographic projections of the two water level probes on a plane perpendicular to the direction of liquid flow at least partially overlap, the detection areas can be partially overlapped in space. This allows the two probes to completely cover the flow cavity 53 in the direction perpendicular to the liquid flow.

[0122] This ensures that when the liquid flows through the flow cavity 53, it can simultaneously cover the effective detection area of ​​the two water level probes, avoiding detection blind spots caused by liquid flow direction deviation or uneven flow field distribution, thereby improving the accuracy of the detection device.

[0123] Understandably, when the liquid level is below the tip of one water level probe, the other water level probe is not in contact with the liquid, there is no electrical connection between the two probes, the circuit is broken, and the detection circuit outputs a signal (such as a low level or a "no water" state). When the liquid level is above the tip of the other water level probe, both probes are in contact with the liquid, and there is electrical connection between them. The water acts as a conductive medium, connecting the circuit between the two probes, and the detection circuit outputs another signal (such as a high level or a "water present" state). Here, the tips of the water level probes are all located at the ends of a portion of the structure within the flow cavity 53.

[0124] This setting allows for the issuance of a signal indicating no water (including water and cleaning fluid) when the liquid level is insufficient to support the flow of liquid from the outlet 52, thereby improving the accuracy of liquid level detection.

[0125] For example, in the vertical direction (z-direction), one end of the water level probe located on the bottom wall 57 within the flow cavity 53 is higher than the end of the outlet 52 near the bottom wall 57. In the vertical direction (z-direction), one end of the water level probe located on the top wall 56 within the flow cavity 53 is flush with the end of the outlet 52 near the bottom wall 57.

[0126] By setting the water level probe located on the bottom wall 57 higher than the bottom of the outlet 52, it is possible to ensure that a certain liquid level is always maintained in the flow cavity 53, maintain continuous contact between the water level probe and the liquid, ensure continuous detection, prevent frequent switching of the detection signal due to liquid draining, and thus improve detection stability.

[0127] By positioning the water level probe located on the top wall 56 flush with the bottom of the outlet 52, the probe is only triggered when liquid can flow out of the outlet 52. This design accurately determines whether the liquid has reached a flowable state, effectively identifies abnormal liquid levels caused by insufficient flow or air resistance, and avoids false detections caused by localized liquid level fluctuations.

[0128] In one possible implementation, see [link to previous section] Figure 10 As shown, a baffle wall 55 is provided inside the flow cavity 53. The baffle wall 55 covers the end of the liquid outlet 52 facing the flow cavity 53, and has an opening at the end facing the inclined wall 54, allowing the liquid outlet 52 to communicate with the flow cavity 53 through the opening. The baffle wall 55 further guides and stabilizes the liquid flow, preventing the liquid from directly impacting the liquid outlet 52, ensuring the stability of the liquid surface in the detection area. Simultaneously, the opening design ensures smooth liquid outflow, further optimizing the detection environment and improving detection accuracy.

[0129] The above embodiments describe the transfer station 21 as a three-way structure. Of course, in some embodiments, the transfer station 21 can also be other structures.

[0130] like Figure 11 As shown, the transfer station 21 can be a disc-shaped structure. The interior of the transfer station 21 can be equipped with a mixing chamber 214. The mixing chamber 214 is configured to pre-mix the water from the raw water tank 11 and the cleaning liquid from the cleaning liquid tank 12 into a uniform mixed solution, and then transport it to the cleaning chamber 131 through the outlet 213.

[0131] By setting up a transfer station 21, water and cleaning fluid are pre-mixed into a mixed solution before being delivered to the cleaning chamber 131. This ensures that the concentration of the cleaning fluid entering the cleaning chamber 131 is uniform, thereby providing a stable and effective cleaning effect for the shaver head 210 and avoiding the problem of insufficient local cleaning power caused by uneven mixing of cleaning fluid and water in the cleaning chamber 131.

[0132] Combination Figure 11 , Figure 12 and Figure 13 As shown, the transfer station 21 has a disc-shaped structure, which may include an end cap 215 and a base 216. The base 216 has a groove structure 2161, and the end cap 215 has a protruding sealing part 2151. When the end cap 215 covers the side of the base 216 with the groove structure 2161, the sealing part 2151 is sealed within the groove structure 2161, forming a mixing cavity 214 between the sealing part 2151 and the groove structure 2161. The end cap 215 and the base 216 can be fixedly connected by welding or snap-fitting. Welding can be ultrasonic welding.

[0133] The structure of the mixing chamber 214 is described below.

[0134] See also Figure 14 As shown, the mixing chamber 214 is S-shaped. In the direction of liquid flow within the mixing chamber 214, the first inlet 211 and the second inlet 212 are located at one end of the S-shape, and the outlet 213 is located at the other end. This S-shaped structure extends the fluid flow path, increases the turbulence and contact time of water and cleaning fluid within the chamber, thereby promoting thorough and uniform mixing. This helps improve the quality of the mixed solution and the stability of the cleaning effect.

[0135] When the transfer station 21 is placed along the z-direction, the first inlet 211 and the second inlet 212 can be located at the bottom (or near the bottom) of the transfer station 21, and the outlet 213 can be located at the top (or near the top) of the transfer station 21. The two liquid streams collide with each other near the first inlet 211 and the second inlet 212, achieving initial vigorous mixing. The subsequently flowing mixed liquid pushes the previous mixed liquid upward, completing further homogenization as it flows towards the outlet 213, and finally discharging a homogeneous mixed solution from the top outlet 213.

[0136] By placing the first inlet 211 and the second inlet 212 at the same end of the S-shape, and the outlet 213 at the other end of the S-shape, the flow path from the first inlet 211 and the second inlet 212 to the outlet 213 can be further extended, allowing water and cleaning fluid to come into more thorough contact and mix, thereby promoting full and uniform mixing and further improving the quality of the mixed solution and the stability of the cleaning effect.

[0137] In one possible implementation, a detection element (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 detection element is signal-connected or electrically connected to the indicator light. When the detection element 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.

[0138] 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.

[0139] By setting up a detection device to monitor the liquid level of 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.

[0140] For example, the detection element can be a water level detection needle disposed within the wastewater tank 14. By setting the detection element as a water level detection needle, the structure of the detection element can be simplified, thereby reducing costs.

[0141] Of course, in other embodiments, the detection element 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 detection element is not further limited.

[0142] In some embodiments, combined with Figure 15 and Figure 16 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.

[0143] 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.

[0144] 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.
