[0018] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:
[0019] 1. In Scheme 1 and its preferred embodiments, a water circuit component includes a housing, a water pump, and a sealing component.
[0020] The housing is provided with an inlet, an outlet, a through hole, and a pump chamber. The inlet and outlet ends of the through hole and the pump chamber are respectively connected to the inlet and outlet. The water pump is installed in the housing and is adapted to be turned on to pressurize the water flowing through the pump chamber to the outlet, so as to ensure the water pressure at the outlet when the water pressure is low, thus facilitating use. When the water pump is turned on, the water passes through the pump chamber under the action of the water pump, and the force of the water on the sealing component is reduced. When the force of the water at the inlet on the sealing component is less than or equal to the first threshold, the sealing component blocks the through hole, and the water cannot pass through the through hole, so that the water passes through the pump chamber and ensures a better pressurization effect. The sealing component is installed on the housing to open the water passage under hydraulic action when the force exerted by the water at the water inlet exceeds a first threshold, so that water can flow directly out from the water passage under high water pressure, preventing water from being unable to pass through the pump chamber or the water pressure from dropping due to the large water resistance generated by the water pump, thereby ensuring the water pressure at the water outlet and allowing use when the water pump is turned off, reducing the cost of use.
[0021] 2. In Scheme 2 and its preferred embodiments, the water inlet hole is directed towards the sealing member so that the water pressure directly acts on the sealing member, facilitating the opening of the water passage hole.
[0022] 3. In Scheme 3 and its preferred embodiments, the water pump is adapted to prevent the pump chamber from connecting the inlet and outlet when it is shut down, so that the water pressure can be fully applied to the sealing element, which facilitates the movement of the sealing element and opens the water passage, ensuring that water does not pass through the pump chamber.
[0023] 4. In Scheme 4 and its preferred embodiments, a water pressure sensor and a controller are further included. The water pressure sensor is installed at the outlet and is adapted to issue a first signal when the water pressure at the outlet is less than or equal to a second threshold. The controller is electrically connected to the water pump and the water pressure sensor and is adapted to control the water pump to start upon receiving the first signal, thereby achieving automatic start-up of the water pump without the need for manual start-up, which is more convenient. Furthermore, the water pressure sensor, installed at the outlet, is more accurate than detecting the water pressure at the inlet, preventing the water pressure at the outlet from dropping below expectations due to water resistance and / or partial water pressure causing the sealing component to move, thus avoiding inconvenience in use.
[0024] 5. In Scheme 5 and its preferred embodiments, the water pressure sensor is adapted to send a second signal when the water pressure at the outlet is greater than the second threshold, and the controller is adapted to control the water pump to shut down when it receives the second signal. The water pump can shut down automatically to prevent waste.
[0025] 6. In Scheme 6 and its preferred embodiments, the second threshold is greater than the first threshold, so that the water pump is turned on before the sealing component blocks the water passage, to prevent the flow rate from decreasing or the shell from being damaged due to pressure buildup.
[0026] 7. In Scheme 7 and its preferred embodiments, a switch is also included. The switch is adapted to turn on and off to energize or de-energize the water pump, so that the user can choose whether to use the water pump function.
[0027] 8. In Scheme 8 and its preferred embodiments, the sealing component includes a force-applying component and a sealing component. The sealing component is adapted to move under hydraulic force when the force exerted by the water at the inlet hole is greater than a first threshold, so as to open the inlet or outlet end of the water passage. The two ends of the force-applying component act on the housing and the sealing component respectively, and are adapted to move the sealing component to block the inlet or outlet end of the water passage when the force exerted by the water at the inlet hole is less than or equal to the first threshold, thereby achieving sealing under low pressure.
[0028] 9. In Scheme 9 and its preferred embodiments, the sealing element is located inside the water passage hole. The sealing element includes a blocking part and a water passage part integrated with the blocking part. The water passage part is provided with a plurality of water passage holes or there is a water passage gap between the water passage part and the water passage hole to realize water passage. The blocking part is suitable for blocking or opening the water inlet end of the water passage hole, thereby realizing water passage and water stop.
[0029] 10. Solution 10 and its preferred embodiment: a water outlet device, including the above-mentioned water circuit component, having the beneficial effects brought about by the above-mentioned water circuit component. Attached Figure Description

[0044] Unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" used in the claims, description and drawings of this utility model shall be interpreted broadly to refer to any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, integral connection and fixed connection through other devices or components.
[0045] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".
[0046] refer to Figures 1-8 A water outlet device, which can be a shower or faucet, etc. The water outlet device includes a water circuit assembly, a temperature regulating valve 81, a water circuit body 9, and various water circuit valve cores 82, etc.
[0047] refer to Figures 2-4 The water circuit body 9 includes a first body 91 and a second body 92. The first body 91 has a mounting hole 911 and several water outlets 912 communicating with the mounting hole 911. The water outlets 912 can be connected to shower heads, overhead showers, etc. A thermostatic valve 81 is installed on the second body 92 and is used for temperature adjustment. Each water circuit valve core 82 is installed in the mounting hole 911 and corresponds to each water outlet 912. The water circuit valve core 82 is suitable for opening and closing the water outlets 912. The working principle of the water circuit valve core 82 is existing technology and will not be described in detail.
[0048] The water circuit components include housing 1, water pump 2, sealing component 3, water pressure sensor 4, controller 5, power supply 6, and switch 7.
[0049] refer to Figure 4 , Figure 6 The housing 1 is provided with a water inlet 11, a water outlet 12, a water passage 13, and a pump chamber 14. The two ends of the housing 1 are respectively connected to the first body 91 and the second body 92 to realize the connection of the corresponding water channels.
[0050] Water inlet 11, water passage 13, and water outlet 12 are arranged along the first direction 10. Water enters through water through the water inlet 11 along the first direction 10 and is adapted to communicate with the outlet end of the temperature control valve 81. Water exits through the water outlet 12 along the first direction 10 and is adapted to communicate with the mounting hole 911, and is controlled by the water circuit valve core 82 to communicate with each water outlet 912.
[0051] The inlet and outlet ends of the water passage 13 are connected to the inlet 11 and the outlet 12, respectively, and the water passage 13 extends along the first direction 10.
[0052] The pump chamber 14 is connected in parallel with the water passage 13. The water inlet end and the water outlet end of the pump chamber 14 are respectively connected to the water inlet 11 and the water outlet 12. In this embodiment, the water inlet end of the pump chamber 14, the water inlet end of the water passage 13, the water outlet end of the water passage 13 and the water outlet end of the pump chamber 14 are arranged along the first direction 10.
[0053] refer to Figure 7The water pump 2 is installed in the housing 1, and its output end is located inside the pump chamber 14. The water pump 2 is adapted to be turned on to pressurize the water flowing through the pump chamber 14 to the outlet 12, and to prevent the pump chamber 14 from connecting the inlet 11 and the outlet 12 when turned off. The water pump 2 can be a conventional impeller pump, piston pump, etc., and its working principle is existing technology and will not be described in detail. In this embodiment, the water pump 2 is an impeller pump, and the output end of the water pump 2 is an impeller. The impeller rotates inside the pump chamber 14 to achieve the pressurization effect. When the water pump 2 is not started, the resistance of the impeller prevents the pump chamber 14 from connecting the inlet 11 and the outlet 12. Of course, in other embodiments, when the water pump 2 is not started, the pump chamber 14 can connect the inlet 11 and the outlet 12. For example, in the case of an impeller pump, there is a gap between the impeller and the pump chamber 14.
[0054] refer to Figure 6 , Figure 8 The sealing element 3 is installed on the housing 1. The sealing element 3 is adapted to open the water passage 13 under the action of water force when the force exerted by water on the water inlet 11 is greater than the first threshold, and to block the water passage 13 when the force exerted by water on the water inlet 11 is less than or equal to the first threshold. Specifically, the sealing component 3 includes a force-applying component 32 and a sealing component 31. The sealing component 31 includes a sealing part 311 and a water-passing part 312 integrated with the sealing part 311. The water-passing part 312 is provided with a plurality of water-passing holes 3121 (or there is a water-passing gap between the water-passing part 312 and the water-passing hole 13). The sealing component 31 is located inside the water-passing hole 13. The sealing part 311 is adapted to move under the action of water force when the force exerted on it by the water at the water inlet hole 11 is greater than a first threshold (sliding in this embodiment, rotation in other embodiments, etc.) to open the water inlet end of the water-passing hole 13, so that water passes through the water inlet hole 11, the water inlet end of the water-passing hole 13, the water-passing holes 3121 on the sealing component 3, the water outlet end of the water-passing hole 13, and the water outlet hole 12 in sequence.
[0055] The force-applying component 32 is located inside the water passage 13. In this embodiment, the force-applying component 32 is a spring; however, in other embodiments, it can be other components, such as magnetic components. The two ends of the force-applying component 32 act on the wall of the water passage 13 of the housing 1 and the water passage portion 312 of the sealing component 31, respectively. The force-applying component 32 is adapted to apply a force opposite to the first direction 10 to the sealing component 31, causing it to move towards the water inlet end of the water passage 13. This is suitable for moving the sealing component 31 when the force exerted by the water at the water inlet 11 is less than or equal to a first threshold, thereby sealing the water inlet end of the water passage 13. In other embodiments, the sealing component 31 can achieve the same effect by sealing the water outlet end of the water passage 13. In this case, the sealing component 31 and the force-applying component 32 can be installed at the water outlet 12. To facilitate the force applied to the sealing component 31, the water inlet direction of the water inlet 11 directly points towards the sealing component 31 to prevent water loss.
[0056] refer to Figure 2 , Figure 7 The water pressure sensor 4 is installed in the housing 1 and at the water outlet 12. The water pressure sensor 4 is adapted to emit a first signal when the water pressure at the water outlet 12 is less than or equal to a second threshold, and to emit a second signal when the water pressure at the water outlet 12 is greater than the second threshold.
[0057] The controller 5 is electrically connected to the water pump 2 and the water pressure sensor 4, and is adapted to control the water pump 2 to turn on when a first signal is received, and to control the water pump 2 to turn off when a second signal is received. Preferably, the second threshold is greater than the first threshold to prevent the water pump 2 from not being turned on before the sealing member 3 seals the water passage 13. Of course, optionally, the second threshold can also be equal to or less than the first threshold, but it is necessary to determine whether it is low-pressure water flow or water stoppage to prevent the water pump 2 from dry burning.
[0058] Power supply 6 supplies power to the aforementioned electrical components. Power supply 6 can be in the form of a battery, which is then an internal power supply 6, or it can be an external power supply 6 (such as AC power).
[0059] The switch 7 is adapted to open or close so that the power supply 6 is electrically connected to or disconnected from the water pump 2, thereby autonomously selecting whether to activate the water pump 2.
[0060] In use, under high pressure, i.e., when the water pressure sensor 4 senses that the water pressure at the outlet 12 is greater than the second threshold, the water pressure sensor 4 sends a second signal, which is received by the controller 5 to ensure that the water pump 2 is shut off. The water pressure entering through the inlet 11 acts directly on the seal 31, and the force applied to the seal 31 is greater than the first threshold. The sealing part 311 of the seal 31 opens the water inlet end of the water passage 13, and the force-applying part 32 stores energy. Water flows sequentially through the inlet 11, the water passage 13, and the outlet 12, and flows to the outlet 912 under the action of the water valve core 82.
[0061] Under low pressure conditions, i.e., when the water pressure sensor 4 detects that the water pressure at the outlet 12 is less than or equal to the second threshold, the water pressure sensor 4 sends a first signal. The controller 5 receives the first signal and starts the water pump 2 to increase the pressure. Water from the inlet 11 enters the outlet 12 through the pump chamber 14 (some water may also flow through the water passage 13), and flows to the outlet 912 under the action of the water valve core 82. Since most of the water passes through the pump chamber 14 under the action of the water pump 2, the force of the water at the inlet 11 on the seal 31 is reduced. When the force of the water on the seal 31 is less than or equal to the first threshold, the seal 31 blocks the water passage 13 under the action of the force-applying component 32, so that water only passes through the pump chamber 14. This ensures that the water pressure at the outlet is maintained at a high level during the shower, making it convenient to use.
[0062] When the user does not want to increase the pressure through the water pump 2, the water pump 2 is disconnected from the power supply 6 by the switch 7, and the water pump 2 will not work. At this time, under low pressure, if the pump chamber 14 is connected to the inlet hole 11 and the outlet hole 12, the water at the inlet hole 11 can reach the outlet hole 12 through the pump chamber 14 and the water passage hole 13. If the pump chamber 14 is not connected to the inlet hole 11 and the outlet hole 12, the water can accumulate at the inlet hole 11 until the force exerted by the water pressure on the seal 31 is greater than the first threshold, and the water reaches the outlet hole 12 through the water passage hole 13.
[0063] Compared with the prior art, this embodiment has the following beneficial effects:
[0064] In one exemplary embodiment, a water circuit assembly includes a housing 1, a water pump 2, and a sealing component 3.
[0065] The housing 1 is provided with a water inlet 11, a water outlet 12, a water passage 13, and a pump chamber 14. The water inlet and outlet ends of the water passage 13 and the pump chamber 14 are respectively connected to the water inlet 11 and the water outlet 12. The water pump 2 is installed in the housing 1 and is adapted to be turned on to pressurize the water flowing through the pump chamber 14 to the water outlet 12, so as to ensure the water pressure at the water outlet 12 when the water pressure is low, thus facilitating use. When the water pump 2 is turned on, the water passes through the pump chamber 14 under the action of the water pump 2, and the force of the water force on the sealing member 3 is reduced. When the force of the water at the water inlet 11 on the sealing member 3 is less than or equal to the first threshold, the sealing member 3 blocks the water passage 13, and the water cannot pass through the water passage 13, so that the water passes through the pump chamber 14, ensuring a better pressurization effect. The sealing component 3 is installed on the housing 1. It is adapted to open the water passage 13 by hydraulic force when the force exerted by the water at the water inlet 11 is greater than the first threshold, so that water can flow directly out from the water passage 13 under high water pressure, preventing water from being unable to pass through the pump chamber 14, or the problem of water pressure reduction due to the large water resistance generated by the water pump 2, thereby ensuring the water pressure at the water outlet 12 and allowing use when the water pump 2 is turned off, reducing the cost of use.
[0066] In one exemplary embodiment, the water inlet 11 is directed toward the sealing member 3 so that the water pressure directly acts on the sealing member 3, facilitating the opening of the water passage 13.
[0067] In one exemplary embodiment, the water pump 2 is adapted to disconnect the pump chamber 14 from the inlet hole 11 and the outlet hole 12 when it is shut down, so that the water pressure can be fully applied to the sealing member 3, which facilitates the movement of the sealing member 3 and opens the water passage hole 13, ensuring that water does not pass through the pump chamber 14.
[0068] In one exemplary embodiment, the system further includes a water pressure sensor 4 and a controller 5. The water pressure sensor 4 is installed at the water outlet 12 and is adapted to emit a first signal when the water pressure at the water outlet 12 is less than or equal to a second threshold. The controller 5 is electrically connected to the water pump 2 and the water pressure sensor 4 and is adapted to control the water pump 2 to start upon receiving the first signal, thereby achieving automatic start-up of the water pump 2 without the need for manual start-up, which is more convenient. Furthermore, the water pressure sensor 4, installed at the water outlet 12, is used to detect the water pressure at the water outlet 12. Compared to detecting the water pressure at the water inlet 11, this method is more accurate and prevents the water pressure at the water outlet 12 from dropping below expectations due to water resistance of the water pump 2 and / or partial water pressure causing the sealing member 3 to move, thus avoiding inconvenience caused by the water pressure at the water pump 2.
[0069] In one exemplary embodiment, the water pressure sensor 4 is adapted to send a second signal when the water pressure at the water outlet 12 is greater than a second threshold, and the controller 5 is adapted to control the water pump 2 to shut down when the second signal is received, so that the water pump 2 can shut down automatically to prevent waste.
[0070] In one exemplary embodiment, the second threshold is greater than the first threshold, so that the water pump 2 is turned on before the sealing member 3 blocks the water passage 13, to prevent the flow rate from decreasing or the housing 1 from being damaged due to pressure buildup.
[0071] In one exemplary embodiment, a switch 7 is also included, which is adapted to turn on or off to energize or de-energize the power supply 6 to the water pump 2, so that the user can choose whether to use the function of the water pump 2.
[0072] In one exemplary embodiment, the sealing member 3 includes a force-applying member 32 and a sealing member 31. The sealing member 31 is adapted to move under the action of water force when the force exerted on it by the water at the water inlet 11 is greater than a first threshold, so as to open the water inlet end or water outlet end of the water passage 13. The two ends of the force-applying member 32 act on the housing 1 and the sealing member 31 respectively, and are adapted to move the sealing member 31 to block the water inlet end or water outlet end of the water passage 13 when the force exerted on it by the water at the water inlet 11 is less than or equal to the first threshold, thereby achieving sealing under low pressure.
[0073] In one exemplary embodiment, the sealing element 31 is located inside the water passage hole 13. The sealing element 31 includes a blocking part 311 and a water passage part 312 integrated with the blocking part 311. The water passage part 312 is provided with a plurality of water passage holes 3121 or there is a water passage gap between the water passage part 312 and the water passage hole 13 to realize water passage. The blocking part 311 is adapted to block or open the water inlet end of the water passage hole 13, thereby realizing water passage and water stop.
[0074] In one exemplary embodiment, a water outlet device includes the aforementioned water circuit component and has the beneficial effects brought about by the aforementioned water circuit component.
