Detailed Implementation
[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0019] It should be understood that the term "and / or" used herein is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0020] It should be understood that the terms "comprising," "including," or any other variations used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0021] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0023] Existing cleaning systems mainly consist of solenoid valves, pressure reducing valves, flow meters, air isolation valves, heaters, distribution valves, and a washer. Water enters through the valve body, passes through the solenoid valve, pressure reducing valve, flow meter, and air isolation valve, flows into the heater for heating, and then flows out through the distribution valve to control the water distribution path, allowing water to flow into the washer to achieve functions such as posterior washing, pulse washing, and feminine washing. Existing technical solutions are costly, bulky, and rely on flexible tubing for connections, resulting in complex spatial layouts and inconvenient manufacturing. Furthermore, the integrated flow meter, pressure reducing valve, and solenoid valve result in insufficient flow accuracy, typically exceeding ±2% under the same inlet water pressure and exceeding 60% under different inlet water pressures. This does not meet the flow control requirements for many product functions. For products with water efficiency requirements of level 2 or higher, achieving this accuracy range is difficult, necessitating more precise control components to realize flow control functionality.
[0024] This application provides a water circuit integration device, which is a water circuit integration device for a smart toilet. Please refer to the details below. Figure 1 , Figure 1 This is a first structural schematic diagram of an embodiment of the water circuit integration device provided in this application. The water circuit integration device includes a solenoid valve 20, a heater 30, a ball pump 40, and a housing 10. The housing 10 has multiple accommodating spaces, with the solenoid valve 20, heater 30, and ball pump 40 located in different accommodating spaces. Water passages are also formed in the housing 10 to connect the different accommodating spaces.
[0025] Specifically, the housing 10 is fixedly connected to the outer shell of the solenoid valve 20, the outer shell of the heater 30, and the outer shell of the ball pump 40. In this embodiment, the housing 10, the solenoid valve 20, and the heater 30 are integrally formed. The inlet and outlet of the ball pump 40 are fixedly connected to the outer shell of the housing 10.
[0026] In this embodiment, by integrating the solenoid valve with the heater and the ball pump, the number of hoses and the spacing between components are reduced compared to the prior art where each component is connected by a silicone hose. The ball pump in this embodiment enables precise control of the water flow rate. Under the same inlet pressure, the ball pump can achieve an accuracy within ±1%, and under different inlet pressures, it can achieve ±3%, making it easier to meet the control requirements of Level 1 water efficiency.
[0027] Furthermore, the housing 10 is also provided with an inlet 101 and an outlet 102, which are located on different sides of the housing 10. In other embodiments, the inlet 101 and the outlet 102 may also be located on the same side of the housing 10.
[0028] The shell 10 contains a first water passage 11, a second water passage 12, and a third water passage 13. Please refer to further details. Figure 2 and Figure 3 , Figure 2 This is a first cross-sectional structural diagram of an embodiment of the water system integration device provided in this application. Figure 3 This is a second cross-sectional structural diagram of an embodiment of the water circuit integrated device provided in this application. The first water circuit channel 11 connects the water inlet 101 of the housing 10 and the water inlet of the ball pump 40; the second water circuit channel 12 connects the water outlet of the ball pump 40 and the water inlet of the heater 30. The third water circuit channel 13 connects the water outlet of the heater 30 and the water outlet 102 of the housing 10.
[0029] The housing 10 is also provided with a fourth water channel 14 and a fifth water channel 15. The fourth water channel 14 connects the first water channel 11 and the inlet of the ball pump 40, and the fifth water channel 15 connects the outlet of the ball pump 40 and the second water channel 12.
[0030] Specifically, the first waterway 11 is arranged along the first direction X, and the second waterway 12 and the third waterway 13 are arranged along the second direction Y. The second waterway 12 and the third waterway 13 are arranged parallel and spaced apart. The fourth waterway 14 and the fifth waterway 15 are arranged along the third direction Z, and the fourth waterway 14 and the fifth waterway 15 are arranged parallel and spaced apart.
[0031] In this embodiment, the first direction X, the second direction Y, and the third direction Z are all set at an angle, meaning they are arranged along different directions. In one specific embodiment, the first direction X and the third direction Z form a 90-degree angle, the second direction Y and the third direction Z form a 90-degree angle, or the first direction X and the second direction Y form a 90-degree angle or an acute angle. Specifically, the first direction X is vertically downward or diagonally downward, meaning the first waterway 11 is set vertically downward or diagonally downward. The second direction Y and the third direction Z are two different directions set along a horizontal plane.
[0032] The fourth waterway channel 14 is arranged perpendicular to the first waterway channel 11 and is connected to the first waterway channel 11. The fifth waterway channel 15 is arranged perpendicular to the second waterway channel 12 and is connected to the second waterway channel 12. Furthermore, the fourth waterway channel 14 and the fifth waterway channel 15 extend in the same direction.
[0033] The housing 10 also includes a first outlet and a second outlet (not labeled in the figure). The first outlet and the second outlet of the housing 10 are located on the same side and are fixedly and sealed to the inlet / outlet of the ball pump 40, respectively. The first outlet and the second outlet of the housing 10 are the end ports of the fourth water channel 14 and the fifth water channel 15, respectively.
[0034] The first water passage 11 is located on different cross-sections from the second and third water passages 12 and 13. Specifically, the second and third water passages 12 are on the same cross-section. The length of the fifth water passage 15 is less than the length of the fourth water passage 14 along the third direction Z, so that the fifth water passage 15 is not connected to the first water passage 11. Water flow direction: Water enters the first water passage 11 from the inlet 101, flows to the fourth water passage 14, enters the spherical pump 40, then flows through the outlet of the spherical pump 40 and the fifth water passage 15 into the second water passage 12, then into the heater 30, flows through the outlet of the heater 30 into the third water passage 13, and finally flows out through the outlet 102.
[0035] In other embodiments, the fourth water channel 14 and the fifth water channel 15 can also be omitted; specifically, the inlet and outlet of the spherical pump 40 can be extended. In other embodiments, the length of the fifth water channel 15 is also greater than the length of the fourth water channel 14, and the fifth water channel 15 is staggered with the first water channel 11 so that neither the fifth water channel 15 nor the second water channel 12 is connected to the first water channel 11.
[0036] In this embodiment, the housing 10 is also equipped with a pressure relief valve 50 and a pressure relief water passage 51. The pressure relief valve 50 is located in the fourth water passage 14, and the pressure relief water passage 51 connects the fourth water passage 14 and the third water passage 13. The pressure relief valve 50 diverts the water pressure before it enters the ball pump 40 to the outlet 102 through the pressure relief water passage 51. Specifically, when the water pressure in the water passage is too high, the pressure is relieved through the branch of the pressure relief water passage 51, thereby protecting the ball pump 40 and the housing 10. The pressure relief water passage 51 is connected to the outlet pipe of the heater 30, which is the third water passage 13, and thus connects to the outlet 102.
[0037] In one specific embodiment, the pressure relief valve 50 is disposed in the fourth water passage 14 along the second direction Y. That is, the pressure relief valve 50 is disposed in a direction perpendicular to the fourth water passage 14, and one end of it is connected to the fourth water passage 14. Specifically, the control valve core of the pressure relief valve 50 is connected to the fourth water passage 14. The pressure relief valve 50 is disposed on a branch perpendicular to the fourth water passage 14.
[0038] In this embodiment, the solenoid valve 20 is disposed on the side of the housing 10 away from the ball pump 40, and is disposed opposite to the ball pump 40.
[0039] Furthermore, a solenoid valve control chamber 201 is provided inside the housing 10 to accommodate the valve core of the solenoid valve 20. The solenoid valve control chamber 201 can be located in the first water passage 11, or at the junction of the first water passage 11 and the fourth water passage 14. Specifically... Figure 3 As shown, the solenoid valve control chamber 201 is located at the junction of the first water passage 11 and the fourth water passage 14. In a specific embodiment, the solenoid valve 20 is arranged perpendicular to the first water passage 11 and parallel to the fourth water passage 14. Specifically, the solenoid valve 20 is arranged along the extension line of the fourth water passage 14, that is, it is arranged on the side of the fourth water passage 14 away from the ball pump 40, and is arranged opposite to the ball pump 40 on both sides of the housing 10.
[0040] In this embodiment, the valve cores of the pressure relief valve 50 and the solenoid valve 20 are located on different planes, that is, on different cross-sections. Specifically, the valve core of the solenoid valve 20 is at the front end of the pressure relief valve 50, that is, the valve core of the solenoid valve 20 is located at the end of the fourth water passage 14 near the first water passage 11. The pressure relief valve 50 is located in the middle of the fourth water passage 14, forming a branch of the fourth water passage 14. The water flow is first controlled by the solenoid valve 20 to determine whether it flows into the fourth water passage 14, and then flows to the third water passage 13 through the pressure relief valve 50 and the pressure relief water passage 51. The pressure relief valve 50 can be located at any position in the middle of the fourth water passage 14.
[0041] Furthermore, a first water temperature sensor 61 and a second water temperature sensor 62 are also provided inside the housing 10. Please refer to [link / reference] for details. Figure 4 , Figure 4 This is a second structural schematic diagram of an embodiment of the water circuit integrated device provided in this application. A first water temperature sensor 61 is disposed in the second water circuit channel 12 for detecting the temperature of the cold water end, and a second water temperature sensor 62 is disposed in the third water circuit channel 13 for detecting the temperature of the hot water end.
[0042] The outer casing 10 is further provided with a first pressure plate 611 and a second pressure plate 621. The first pressure plate 611 is used to fix the first water temperature sensor 61, and the second pressure plate 621 is used to fix the second water temperature sensor 62. Specifically, both the first water temperature sensor 61 and the second water temperature sensor 62 include a sensing element inserted into the water channel for sensing water temperature. The first water temperature sensor 61 is disposed in the second water channel 12 along a direction parallel to the second water channel 12 (i.e., along the second direction), as detailed in [reference needed]. Figure 2The first water temperature sensor 61 is disposed in the second water passage 12 in the direction away from the heater 30, that is, in the direction of the extension line of the second water passage 12, and the first water temperature sensor 61 is sealed and connected to the second water passage 12. The second water temperature sensor 62 is disposed in the third water passage 13 in a direction perpendicular to the third water passage 13. Specifically, the second water temperature sensor 62 is disposed in the third water passage 13 in the third direction Z. That is, like the solenoid valve 20, it is disposed on the side of the third water passage 13 away from the ball pump 40. That is, the second water temperature sensor 62 and the second pressure plate 621 are disposed on the same side of the housing 10 as the solenoid valve 20, and are all disposed on the front side of the housing 10. The first pressure plate 611 is disposed on the side of the outer shell of the housing 10 away from the heater 30, and is used to fix the first water temperature sensor 61. That is, the first pressure plate 611 is disposed on the same side as the outlet 102 of the housing 10.
[0043] Please refer to further details. Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of an embodiment of the spherical pump provided in this application. Figure 6 This is a cross-sectional structural diagram of an embodiment of the spherical pump provided in this application. The spherical pump 40 is a power unit that uses a motor 41 to drive the rotation of a shaft 42 and a piston 43 to move water. The flow rate of the spherical pump is controlled by the water delivery space formed by the cooperation of the shaft 42 and the piston 43. Figure 6 As shown, the spherical pump 40 comprises a motor 41, a rotating shaft 42, a piston 43, a slide 44, and a pipe housing 45. The pipe housing 45 contains an inlet pipe 451 and an outlet pipe 452. A water delivery space is formed between the piston 43 and the rotating shaft 42. When the motor 41 rotates at high speed, a negative pressure is created in the water delivery space, drawing water in through the inlet pipe 451 and discharging it through the outlet pipe 452. Generally, two symmetrical water delivery spaces are provided to improve water delivery efficiency. In this embodiment, based on the required flow rate, the capacity of a single water delivery space is set to 0.45 mL / r. To ensure the accuracy and stability of the water delivery flow rate of the spherical pump 40, the fitting clearance between the spherical surfaces of the piston 43 and the rotating shaft 42 and the motor housing 411 and the pipe housing 45 needs to be controlled. In this embodiment, the fitting clearance between the spherical surfaces of the piston 43 and the rotating shaft 42 and the motor housing 411, as well as with the pipe housing 45, is less than or equal to 0.03 mm. It should be noted that if any gap is greater than 0.03mm, the flow deviation inside the ball pump will exceed ±2%, resulting in poor precision control.
[0044] The water delivery space comprises a first water delivery space 401 formed on the side facing the inlet pipe 451 and a second water delivery space 402 formed on the side facing the outlet pipe 452. Specifically, the sizes of the first water delivery space 401 and the second water delivery space 402 are controlled by the piston 43 and the rotating shaft 42. Figure 6As shown, the water delivery space of the second water delivery space 402 is larger than that of the first water delivery space 401. In other embodiments, the water delivery space of the first water delivery space 401 may also be larger than that of the second water delivery space 402. The piston 43 rotates axially along the shaft core 421 of the rotating shaft 42, thereby transporting water from the first water delivery space 401 to the second water delivery space 402, and then flowing out from the outlet pipe 452 connected to the second water delivery space 402.
[0045] In this embodiment, the solenoid valve 20 and the ball pump 40 are respectively disposed on opposite sides of the housing 10, the heater 30 is disposed on one side of the housing 10 and the solenoid valve 20 and the ball pump 30, and the outlet 102 is disposed on the side of the housing 10 away from the heater 30. Specifically, the solenoid valve 20 is disposed on the front side of the housing 10, the ball pump 40 is disposed on the rear side of the housing 10, and the heater 30 is disposed on the right side of the housing 10. The outlet 102 is disposed on the left side of the housing 10. The inlet 101 and the outlet 102 are disposed on different layers of the housing 10, and further, the inlet 101 is disposed on the lower side of the housing 10.
[0046] The heater 30 also includes a thermostat 31 and a fuse 32. The fuse 32 and the thermostat 31 respectively control the heating temperature and protect the heater 30. The thermostat 31 is located on the surface of the heater 30 housing facing the solenoid valve 20, and the fuse 32 is located on the surface of the heater 30 housing away from the ball pump 40. By placing the thermostat 31 and the fuse 32 on the two exposed surfaces of the heater 30, the heater 30 can be tightly connected to the solenoid valve 20 and the ball pump 40, saving space occupied by the overall structure.
[0047] In this embodiment, the heater 30 is a plate heater, and the interior of the heater 30 is divided into two heating chambers by heating plates 33, such as... Figure 2 As shown, water flows into the lower chamber 301 of the heater through the second water channel 12, passes through the heating element 33 and enters the upper chamber 302 of the heater, where it is heated rapidly. Then, it enters the third water channel 13 from the upper chamber 302 of the heater.
[0048] In other embodiments, heater 30 may also be a tubular heater; please refer to the following for details. Figure 7 , Figure 7 This is a schematic diagram of the second embodiment of the housing provided in this application. The housing 10, solenoid valve 20, and ball pump 40 remain structurally unchanged. The heater 30 is a tubular heater, located on the right side of the housing 10. The tubular heater provides more stable heating control.
[0049] This application also provides another integrated water system device, please refer to [link / reference needed]. Figure 8 , Figure 8This is a structural schematic diagram of the third embodiment of the water system integration device provided in this application. Figure 8 As shown, the water inlet 101 is angled downwards, thus changing the water inlet pipe to a side-facing water inlet. Furthermore, the water inlet 101 can also be located on the same side as the water outlet 102. By changing the orientation of the water inlet pipe, it facilitates the use of split-type units.
[0050] This application also provides a cleaning system; please refer to further details. Figure 9 , Figure 9 This is a schematic diagram of the framework of an embodiment of the cleaning system provided in this application. Figure 9 As shown, the cleaning system includes the water circuit integration device described in any of the above embodiments, as well as an air isolation valve 70, a distribution valve 80, and a cleaner 90.
[0051] The solenoid valve 20, the ball pump 40, and the heater 30 are integrated on the housing 10 and fixed together with the housing 10, or integrally formed.
[0052] In this embodiment, the air isolation valve 70, the distribution valve 80, the cleaner 90, and the water outlet of the housing 10 are connected by a hose.
[0053] In this embodiment, water enters through the inlet of the housing 10, passes through the solenoid valve 20, enters the ball pump 40 through the inlet pipe (i.e., the fourth water channel 14), and then flows out through the outlet pipe (i.e., the fifth water channel 15) of the ball pump 40. It then enters the heater 30 through the inlet pipe (second water channel 12) of the heater 30, and then flows out through the outlet pipe (third water channel 13) of the heater 30. After exiting the heater 30, the water flows through the air isolation valve 70, the distribution valve 80, and the cleaner 90 in sequence, forming a water spray.
[0054] This application also provides a smart toilet; please refer to further details. Figure 10 , Figure 10 This is a structural schematic diagram of an embodiment of the smart toilet provided in this application. Figure 10 As shown, the smart toilet integrates the cleaning system described in the above embodiment. The housing 10, solenoid valve 20, and heater 30 are integrally formed into a single unit. A ball pump 40 is fixedly and sealed to the housing 10. Specifically, the housing 10 has inlet and outlet on the side opposite to the solenoid valve 20, for fixed and sealed connection with the inlet and outlet of the ball pump 40. The air isolation valve 70, distribution valve 80, washer 90, and outlet 102 of the housing 10 are connected via flexible hoses.
[0055] The beneficial effects of this application are as follows: The inlet and ball pump are connected through a first water channel within the housing; the ball pump and heater are connected through a second water channel; and the heater and outlet are connected through a third water channel. This integrates the solenoid valve, ball pump, and heater together through the water channels within the housing, reducing the water flow path between them, improving their integration, and enhancing the ball pump's control accuracy of water flow. It also reduces the number of components between the solenoid valve, heater, and ball pump, minimizing leakage points and improving the stability of the water circuit. Furthermore, the housing effectively reduces the assembly cost between the solenoid valve, heater, and ball pump. This application also utilizes the ball pump to achieve precise control of water flow, achieving an accuracy within ±1% under the same inlet pressure and ±3% under different inlet pressures.
[0056] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
