Abstract
Description
Technical Field
[0001] The present application relates to the technical field of toilets, and in particular to a hybrid power flushing system and an energy-saving toilet. Background Art
[0002] The existing water pump flushing system of toilets on the market generally sends external water (such as tap water) to the water tank, and then pumps the water in the water tank to flush the toilet through the water pump. Therefore, the energy of the flushing water circuit of the toilet comes from the water pump. However, due to the need to control the cost of toilet products, the water pump used in the toilet is not powerful enough, which makes the sewage discharge capacity during flushing relatively general, especially when encountering hard dirt or a lot of paper towels, it is easy to get clogged, which leads to a poor customer experience.
[0003] When the water pressure of the external water source is low, this part of the water pressure energy cannot be fully utilized. The flushing system mainly uses a constant-power water pump to pump the water in the water tank for flushing. Therefore, the water pump can play the role of converting electrical energy into kinetic energy to deliver water for flushing; however, when the water pressure of the external water source is high, the existing toilet sends the external water source to the water tank, and then the water is pumped by the water pump. The energy for delivering water still comes from the water pump, and the energy of the external water source water pressure energy is not fully utilized. The free energy is not utilized, which is not energy-saving and environmentally friendly.
[0004] Moreover, the toilet flushing system design scheme mentioned above on the market, which sends external water source to the water tank and then is pumped by a water pump, adopts a single water pump flushing system and only uses the energy of the water pump. Therefore, in order to improve the flushing effect, the power of the water pump must be increased. A high-power water pump consumes more electricity, the water pump itself is larger in size, consumes more materials, and is more expensive. All of these will be passed on to consumers, reducing the cost-effectiveness of the toilet cost. Summary of the invention

DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments; the technical features designed in different implementation modes of the present application described below can be combined with each other as long as they do not conflict with each other; based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0024] In the description of this application, it should be noted that all terms (including technical terms and scientific terms) used in this application have the same meanings as those generally understood by ordinary technicians in the field to which this application belongs, and cannot be understood as limitations on this application; it should be further understood that the terms used in this application should be understood to have meanings consistent with the meanings of these terms in the context of this specification and in the relevant fields, and should not be understood in an idealized or overly formal sense, unless explicitly defined in this application.
[0025] This application provides Figure 1-15 The energy-saving intelligent toilet shown in Example 1 at least includes a toilet body 800 and a hybrid power flushing system.
[0026] The hybrid water flushing system comprises a water tank 100, a jet water delivery pipe 200 for flushing the bottom of a toilet body 800, a scrubbing water delivery pipe 300 for flushing the peripheral wall of the toilet body 800, a power pump 400, and a water inlet valve mechanism 500 arranged in the water tank 100. The water inlet end of the power pump 400 is connected to the water tank 100, and the water outlet end thereof is respectively connected to the water inlet of the scrubbing water delivery pipe 300 and the water inlet of the jet water delivery pipe 200, so as to supply water to the scrubbing water delivery pipe 300 and the jet water delivery pipe 200. The water inlet valve mechanism 500 comprises a water source water inlet end 510 for an external water source to flow in, a first water outlet pipe 520 and a second water outlet pipe 530 for supplying water to the water tank 100, and a first valve structure 540 and a second valve structure 550 for respectively controlling the flow path between the first water outlet pipe 520 and the second water outlet pipe 530 and the water source water inlet end 510 to be open or closed. The second water outlet pipe 530 is connected to the water inlet of the jet water pipeline 200 so that the external water source flows through the second water outlet pipe 530 to the water outlet of the jet water pipeline 200 for discharge.
[0027] When in use, water flows through the following three paths, wherein the jet water delivery pipeline 200 has two water flow directions, and the scrubbing water delivery pipeline 300 has one water flow direction, as described in detail below.
[0028] When flushing, the water source inlet end 510 of the water inlet valve mechanism 500 is connected to an external water source (for example, a municipal tap water waterway 10, the external water source generally has a hydraulic power) to allow water to flow in, and the first valve structure 540 is opened to connect the water source inlet end 510 and the first water outlet pipe 520, so that the external water source supplies water to the water tank 100 through the first water outlet pipe 520, and the power pump 400 draws water from the water tank 100 and sends it to one of the water inlets of the scrubbing water supply pipe 300 and the water inlet of the jet water supply pipe 200, and the water outlets of the scrubbing water supply pipe 300 and the jet water supply pipe 200 spray water to respectively flush the peripheral wall and the bottom of the toilet body 800. In addition, the second valve structure 550 is opened to connect the water source inlet end 510 and the second water outlet pipe 530. Through the dynamic impact brought by the external water source, the water flows from the second water outlet pipe 530 to the other water inlet of the jet water pipe 200, flows through the jet water pipe 200, and is sprayed from its water outlet to the bottom of the toilet body 800.
[0029] Therefore, one water channel of the jet water pipe 200 of the above-mentioned hybrid water flushing system can fully utilize the water pressure kinetic energy of the external water source for water spraying and flushing, and since the water outlet of the jet water pipe 200 is designed at the bottom of the toilet body 800, this water channel also has a certain gravitational potential energy. By utilizing the energy other than the power pump 400 mentioned above, the power pump 400 of the hybrid power flushing system can adopt a low-power power pump 400 (the low power here means: when the toilet can achieve the same flushing effect, compared with the pump used in the existing flushing system that only uses a water pump as the kinetic energy source, the power of the power pump required for use in this application is smaller), a part of the power water of the power pump 400 flows to the scrubbing water pipe 300 for washing (i.e., flushing the surrounding wall of the toilet body 800), and another part of the power water of the power pump 400 flows to one water channel of the jet water pipe 200 to spray the bottom of the toilet body 800, and the other water channel of the jet water pipe 200 is started through the second valve structure 550, so as to make full use of the water pressure kinetic energy of the water source to transport water to the bottom of the toilet body 800 for spraying, thereby achieving energy saving effect. At the same time, the two water channels spray at the bottom of the toilet, which can achieve better flushing and sewage discharge effect.
[0030] Optionally, the hybrid power flushing system further includes a reversing mechanism 600. The water inlet end of the reversing mechanism 600 is connected to the water outlet end of the power pump 400, the first outlet 610 of the reversing mechanism 600 is connected to the water inlet of the scrubbing water pipeline 300, and the second outlet 620 thereof is connected to the water inlet of the jetting water pipeline 200. The reversing mechanism 600 is used to switch the water source of the water outlet end of the power pump 400 to selectively connect the scrubbing water pipeline 300 and / or the jetting water pipeline 200, so as to supply water to the scrubbing water pipeline 300 and the jetting water pipeline 200.
[0031] like Figure 2 , Figure 8-9 As shown, the flow path formed by the water inlet end of the reversing mechanism 600 and its first outlet 610 and the flow path formed by the water inlet end and its second outlet 620 can be selectively connected, so that the reversing mechanism 600 can be used to switch the water source of the water outlet end of the power pump 400 to selectively connect the scrubbing water pipeline 300 or the jetting water pipeline 200. With the above design, the power water of the power pump 400 can be freely switched on or off in the two different flow paths of the scrubbing water pipeline 300 and the jetting water pipeline 200, and the control of each flow path is more flexible and convenient to use. For example, in actual use, according to the needs, it can be switched to the scrubbing water pipeline 300 for washing the toilet, and then switched to the jetting water pipeline 200 to spray water on the bottom of the toilet.
[0032] It should be noted that: for the conduction order and interval time of the power water of the power pump 400 in the two different flow paths of the scrubbing water pipeline 300 and the jet water pipeline 200, technical personnel in this field can set them according to their needs, including but not limited to the solution that the power water of the power pump 400 first goes to the scrubbing water pipeline 300 and then to the jet water pipeline 200.
[0033] Optionally, the second valve structure 550 is a hydraulic on-off water flow device. The water inlet triggering end of the hydraulic on-off water flow device is connected to the second outlet 620 of the reversing mechanism 600 through the first opening pipe 560. When the water pressure of the water flowing from the second outlet 620 to the water inlet triggering end of the hydraulic on-off water flow device is greater than or equal to a predetermined value, the hydraulic on-off water flow device is triggered to open the flow path between the water source water inlet end 510 and the second water outlet pipe 530. When the water pressure of the water flowing from the second outlet 620 to the water inlet triggering end of the hydraulic on-off water flow device is lower than a predetermined value, the hydraulic on-off water flow device is not triggered to close the flow path between the water source water inlet end 510 and the second water outlet pipe 530.
[0034] like Figure 2-4 , Figure 8-9 As shown, the opening and closing of the second valve structure 550 can be controlled by the hydraulic control principle: when in use, the reversing mechanism 600 switches to the second outlet 620 to open, and the pump power water flows to the jet water pipeline 200 at the second outlet 620 in one way, and also flows to the water inlet trigger end of the second valve structure 550 (hydraulic on-off water flow device) through the first opening pipe 560. At this time, the water flow in the first opening pipe 560 has a certain water pressure energy. When the water pressure energy is greater than or equal to a certain predetermined value, the hydraulic on-off water flow device can open the flow path between the water source water inlet end 510 and the second water outlet pipe 530, and the water flow of the second water outlet pipe 530 flows to the jet water pipeline 200 to enhance the injection. Similarly, when there is no water flow in the first opening pipe 560, the water flow is stationary, or the water flow pressure is too small, the flow path between the water source water inlet end 510 and the second water outlet pipe 530 is closed, and the jet water pipeline 200 does not perform the second enhanced injection.
[0035] Specifically, the control process of the hydraulic on-off water flow device (using a diaphragm valve-like structure) of this embodiment 1 is as follows: the water flow action of the first open pipe 560 pushes the first diaphragm 551 to deform, driving the first spring 552 to compress, thereby lifting the first lever 553, the top of the first lever 553 originally presses the first pressure relief sealing sheet 555 to block the first pressure relief port 554, and after the first lever 553 is lifted, the first pressure relief sealing sheet 555 is pulled out, so that the first pressure relief port 554 is opened, thereby achieving the effect of the hydraulic on-off water flow device conducting the flow path driven by the water flow power of the first open pipe 560. On the contrary, when there is no water flow in the first open pipe 560, the water flow is stationary, or the water flow pressure is too small, the first spring 552 is reset and the first pressure relief port 554 is sealed.
[0036] It should be noted that the hydraulic control principle of the hydraulic on-off water flow device of the present embodiment 1 is the same as that of the existing diaphragm valve: the diaphragm valve realizes the opening and closing control of the corresponding valve port by changing the pressure on both sides of the diaphragm to deform the diaphragm. Therefore, the existing diaphragm valve structure can be selected for the structural design of the hydraulic on-off water flow device, and its structure and working principle are not described in detail here.
[0037] In addition, the second valve structure 550 may also adopt existing valve structures of other control principles, such as a solenoid valve for controlling the flow path between the water source inlet end 510 and the second water outlet pipe 530 to be open or closed, including but not limited to the above-mentioned hydraulic on-off water flow device (i.e., diaphragm valve) solution. The purpose of using the above-mentioned hydraulic on-off water flow device in this embodiment 1 is that compared with other valves such as solenoid valves, which require other auxiliary energy for their normal operation, the hydraulic on-off water flow device only needs to use the existing water power to control its automatic opening and closing, which is energy-saving and automatic.
[0038] Optionally, a first valve structure 540 is provided on the connection passage between the water source inlet end 510 and the first water outlet pipe 520. The first valve structure 540 is a float 541 limiting device, wherein when the liquid level of water in the water tank 100 is lower than a predetermined value, the float 541 limiting device enables the flow path between the water source inlet end 510 and the first water outlet pipe 520 to be conducted. When the liquid level of water in the water tank 100 is higher than or equal to a predetermined value, the float 541 limiting device closes the flow path between the water source inlet end 510 and the first water outlet pipe 520.
[0039] When in use, the float 541 limiting device is designed in the water tank 100, and the float 541 is installed in the water tank 100 to sense the liquid level, thereby automatically replenishing and stopping the water tank 100.
[0040] It should be noted that the float 541 limit device is an existing device, and its structure and construction are all existing technologies. The design principle of automatically opening and closing the water inlet flow path by sensing the water level is also publicly available, and will not be repeated here. For the float 541 limit device, those skilled in the art can select an adaptive model according to their needs.
[0041] In addition, for the realization of the water jetting effect at the water outlet of the water jetting pipeline 200 and the water outlet partial pressure water discharge effect: Optionally, the jet water delivery pipeline 200 includes a first pipe section 210 and a second pipe section 220. The water inlet of the first pipe section 210 is connected to the second water outlet pipe 530, and the water outlet at the other end thereof is connected to a pressure-dividing water outlet mechanism 240, which is used to divide the water flow at the water outlet of the second pipe section 220 into at least two flow paths for water to flow out. Among them, the pressure-dividing water outlet mechanism 240 has a pressure-limiting opening function. When the water pressure of the water flow at the water outlet of the first pipe section 210 is greater than or equal to a predetermined value, the pressure-dividing water outlet mechanism 240 is opened to divide the water flow into at least two flow paths for water to flow out. When the water pressure of the water flow at the water outlet of the first pipe section 210 is lower than a predetermined value, the pressure-dividing water outlet mechanism 240 is closed to allow the water flow to flow out through one flow path. The water inlet at one end of the second pipe section 220 is connected to the second outlet 620 of the reversing mechanism 600, and the water outlet at the other end flows out water.
[0042] The design of the pressure-dividing water outlet mechanism 240 can control the water from the external water source to the jet water delivery pipe 200 to flow out through one or more flow paths according to the water pressure of the external water source. The pressure-dividing design can avoid the problem of excessive jetting force of the jet water delivery pipe 200 when the water pressure of the external water source is too high. The design of the pressure-dividing water outlet mechanism 240 is added to add a water outlet for high-pressure external water, which helps to increase the water jetting area and jetting force, improve the water pushing force in the pit at the bottom of the toilet, and avoid the problem of excessive noise caused by single-hole high-pressure water jetting.
[0043] Specifically, the pressure-limiting opening function and the pressure-dividing function of the pressure-dividing water outlet mechanism 240 can be realized through the cooperation of the nozzle 241 and the pressure-limiting opening device 242 on the nozzle 241 .
[0044] Optionally, the hybrid power flushing system further includes a nozzle 241. The nozzle 241 includes a main body 2416, a first nozzle water inlet pipe 2411, and a second nozzle water inlet pipe 2412. The main body 2416 is provided with a first spray hole 2413 and a second spray hole 2414 for spraying water, and the outlet ends of the first nozzle water inlet pipe 2411 and the second nozzle water inlet pipe 2412 are respectively connected to the first spray hole 2413 and the second spray hole 2414. The jet water delivery pipeline 200 includes a first pipe section 210 and a second pipe section 220. The water inlet of the first pipe section 210 is connected to the second water outlet pipe 530, and the water outlet thereof is connected to the first nozzle water inlet pipe 2411. The water inlet of the second pipe section 220 is connected to the second outlet 620 of the reversing mechanism 600, and the water outlet thereof is connected to the second nozzle water inlet pipe 2412. Optionally, the main body 2416 is provided with a third spray hole 2415. The third spray hole 2415 is connected to the first nozzle water inlet pipe 2411 through the pressure-limiting opening device 242. When the water pressure of the water flowing from the first nozzle water inlet pipe 2411 to the pressure-limiting opening device 242 is greater than or equal to a predetermined value, the pressure-limiting opening device 242 is opened to allow the water to flow to the third spray hole 2415 for spraying. When the water pressure of the water flowing from the first nozzle water inlet pipe 2411 to the pressure-limiting opening device 242 is lower than a predetermined value, the pressure-limiting opening device 242 is closed.
[0045] like Figure 5-7 As shown, when the external water source flows to the first nozzle water inlet pipe 2411 through the second water outlet pipe 530 and the first pipe section 210, the first nozzle water inlet pipe 2411 is connected to the water inlet end of the pressure limiting opening device 242. When the water pressure here is greater than or equal to a predetermined value, the pressure limiting opening device 242 opens to allow the water to flow to the third spray hole 2415 connected thereto and spray out. On the contrary, when the water pressure is lower than the predetermined value, the pressure limiting opening device 242 is closed, and the water cannot be sprayed out from the third spray hole 2415.
[0046] It should be noted that: like Figure 7 As shown, the control principle of the pressure limiting opening device 242 used in this embodiment 1 is the same as that of the existing pressure valve. When in use, the water flow action pushes the second diaphragm 2421 to deform, driving the second spring 2422 to compress and open the valve port, thereby opening the water inlet and outlet channels of the pressure limiting opening device 242. Therefore, the existing structure can be selected for the structure of the pressure limiting opening device 242, and its structure and working principle will not be repeated here.
[0047] In this embodiment 1, the nozzle 241 of the three-hole spray hole is designed to realize the two-hole water spraying splitting of one water channel. According to the above design concept, the design of the number and position of the split-pressure water spraying holes of one water channel can be adjusted according to the actual needs, including but not limited to the solution of embodiment 1.
[0048] In addition, the partial pressure water outlet design of Example 1 is a preferred embodiment of the present application and is not a mandatory option. When the flushing system is actually used, the partial pressure water outlet design may not be performed. For example, Figure 16-17 As shown, the nozzle 241 is only designed with a first nozzle water inlet pipe 2411 and a second nozzle water inlet pipe 2412, and the first nozzle water inlet pipe 2411 and the second nozzle water inlet pipe 2412 are correspondingly connected to the first spray hole 2413 and the second spray hole 2414, so that water spraying without partial pressure design can be realized.
[0049] For the internal preset values in the pressure-limiting opening device 242 and the hydraulic air supply mechanism 722 mentioned in this article, those skilled in the art can adaptively adjust the values according to actual needs (under what water pressure value state is required to make the liquid circuit conductive).
[0050] Optionally, the power pump 400 and the reversing mechanism 600 are electrically connected to the control system. If the second valve structure 550 is a solenoid valve, the solenoid valve is electrically connected to the control system.
[0051] By electrically connecting the power pump 400 and the reversing mechanism 600 to the control system, intelligent and automatic control of the states of the power pump 400 and the reversing mechanism 600 is achieved, and the operation of the flushing system is more intelligent and automatic.
[0052] It should be noted that: The control system is a prior art, for example, a PLC controller can be used, which has a programmable memory for storing programs inside, executing user-oriented instructions such as logical operations, sequential control, timing, counting and arithmetic operations, and controlling various types of machinery or production processes through digital or analog input / output. It is a prior art, and the control system will not be described in detail. The working principle of the power pump 400, the reversing mechanism 600, the solenoid valve and the control system to perform signal reception-information processing-feedback-power pump 400, the reversing mechanism 600, and the solenoid valve state adjustment is also a prior art, and will not be described in detail here.
[0053] In this embodiment 1, the control system is configured to include a PCB control panel. The PCB control panel is designed on the reversing mechanism 600 and the power pump 400. The reversing mechanism 600 and the power pump 400 can be controlled by operating the PCB control panel.
[0054] The reversing mechanism 600 is a switching motor controlled by a PCB control panel, wherein the switching motor for switching the flow path is an existing device, and its structure and working principle are not described in detail here.
[0055] To achieve the water jet effect for brushing the water delivery pipeline 300: Optionally, a ring washing nozzle 310 is provided at the water outlet of the scrubbing water delivery pipeline 300 .
[0056] For the system to create a foam shield effect: Optionally, a foam generating mechanism 700 for generating a foam shield is connected between the first outlet 610 of the reversing mechanism 600 and the scrubbing water delivery pipeline 300 .
[0057] Optionally, the foam generating mechanism 700 includes a jet mixer 710 and a foaming liquid storage tank 720. The inlet end of the jet mixer 710 is connected to the first outlet 610, and the outlet end thereof is connected to the scrubbing water delivery pipeline 300. A venturi tube is provided inside the jet mixer 710, and a liquid suction nozzle 711 and an air suction nozzle 712 are provided at the throat of the venturi tube and are communicated with the inside of the jet mixer 710. The liquid suction nozzle 711 is connected to the liquid outlet of the foaming liquid storage tank 720.
[0058] like Figure 2 , Figure 8-10 As shown, the material in the foaming liquid storage tank 720 is connected to the liquid suction nozzle 711 through the liquid outlet. When the first outlet 610 is opened, the water flow for washing the ring flows through the venturi tube. When the water flows out through the venturi tube, a negative pressure suction force is generated at the rear end of the venturi tube nozzle, that is, at the throat of the venturi tube (the working principle of the venturi tube is that the internal part changes from thick to thin from the inlet section, the contraction section to the throat, and is divided into the inlet section, the contraction section, the throat and the diffusion zone according to the flow direction of the fluid. The outlet of the venturi tube The rear side is what is commonly called the throat, where the fluid flows out and diffuses, and a negative pressure zone is formed here when the fluid flows through the inside of the Venturi tube). The liquid suction nozzle 711 and the air suction nozzle 712 generate suction, and the air suction nozzle 712 sucks in the air 20, and the liquid suction nozzle 711 sucks in the material in the foaming liquid storage tank 720, and then they are sucked into the Venturi tube together, mixed in the pipe at the rear end of the Venturi tube outlet to produce foam water, which flows out through the wash ring nozzle 310 to the toilet body 800 to produce a foam shield.
[0059] Optionally, the foaming liquid storage tank 720 includes a sealed tank body 721 with a closed inner cavity, a liquid outlet is provided on the sealed tank body 721, and the liquid outlet is connected to the liquid suction nozzle 711 through the foaming liquid outflow pipe 740. The sealed tank body 721 is provided with a hydraulic air supply mechanism 722, and the trigger end of the hydraulic air supply mechanism 722 is connected to the water outlet end of the power pump 400 through the second opening pipe 730.
[0060] Among them, when the power pump 400 is turned on, the water flow at the water outlet end of the power pump 400 flows to the second open pipe 730, and the water flow in the second open pipe 730 to the hydraulic air supply mechanism 722 can trigger the hydraulic air supply mechanism 722, so that the air 20 outside the sealed tank body 721 enters the air flow path of the top cavity of the inner cavity of the sealed tank body 721 from the hydraulic air supply mechanism 722, so that the air 20 enters the top cavity of the inner cavity of the sealed tank body 721 from the hydraulic air supply mechanism 722.
[0061] Among them, when the power pump 400 is turned off, there is no water flow in the second open tube 730 or the water flow existing in it fails to trigger the hydraulic air supply mechanism 722, so that the air flow passage for the air 20 outside the sealed tank body 721 to enter the top cavity of the inner cavity of the sealed tank body 721 from the hydraulic air supply mechanism 722 is closed, so that the air 20 cannot enter the top cavity of the inner cavity of the sealed tank body 721 from the hydraulic air supply mechanism 722.
[0062] like Figure 1 , Figure 8-10 As shown, the water outlet of the power pump 400 is connected to the water inlet of the reversing mechanism 600 through the second power pump pipe 420, and the water outlet of the second power pump pipe 420 is connected to the second open pipe 730. When the power pump 400 is turned on, the water outlet of the second power pump pipe 420 delivers water to the second open pipe 730, and the second open pipe 730 delivers water to the trigger end of the hydraulic air supply mechanism 722. Under the action of the water flow (self-driven energy), the hydraulic air supply mechanism 722 is triggered to open, so that a small amount of air 20 outside the sealed tank body 721 flows into the cavity at the top of the inner cavity of the sealed tank body 721 through the hydraulic air supply mechanism 722. At this time, the liquid outlet at the bottom of the inner cavity of the sealed tank body 721 squeezes out the foaming liquid 30, and the suction force of the liquid suction nozzle 711 makes the foaming liquid 30 flow to the jet mixer 710. Similarly, when the power pump 400 is turned off, the hydraulic air supply mechanism 722 fails to be triggered, and the foaming liquid 30 in the sealed tank body 721 will not be squeezed out.
[0063] Specifically, the control process of the hydraulic air supply mechanism 722 of the first embodiment is as follows: like Figure 8-15 As shown, the lower part of the inner cavity of the sealed tank body 721 contains a foaming liquid 30 (including but not limited to detergent and other reactive agents that can generate bubbles), and the top is empty. The components of the hydraulic air supply mechanism 722 include a third diaphragm 7224, a movable rod 7221, a first sealing sheet 7222, and a second sealing sheet 7223; wherein, the gap between the movable rod 7221 and the bottom wall of the sealed tank body 721 forms an air passage, which is connected to the opening at the first sealing sheet 7222 and the opening at the second sealing sheet 7223. The first sealing sheet 7222 is opened or closed to connect or close the opening thereto with the air path of the top cavity of the inner cavity of the sealed tank body 721, and the second sealing sheet 7223 is opened or closed to connect or close the opening thereto with the air path of the external air 20.
[0064] like Figure 12-13As shown, in the initial state, the hydraulic air supply mechanism 722 is not triggered, its first sealing plate 7222 is sealed, and the second sealing plate 7223 is open. At this time, the external air 20 enters the air path formed by the gap between the movable rod 7221 and the bottom wall of the sealed tank body 721 from the opening at the second sealing plate 7223, but cannot flow from the opening at the first sealing plate 7222 into the inner cavity of the sealed tank 721. In this closed state, the foaming liquid 30 in the tank will not flow out.
[0065] like Figure 14-15 As shown, when the power pump 400 is turned on, the second opening pipe 730 delivers water, and the water action triggers the deformation of the third diaphragm 7224, driving the movable rod 7221 to move upward. At this time, the movable rod 7221 pushes the first sealing sheet 7222, the first sealing sheet 7222 is opened, and the second sealing sheet 7223 is sealed. At this time, the opening at the second sealing sheet 7223 is sealed so that the external air 20 cannot enter the air path formed by the gap between the movable rod 7221 and the bottom wall of the sealed tank body 721 from the opening, and the opening at the first sealing sheet 7222 is opened, and the small amount of air in the air path in the previous initial state enters the inner cavity of the sealed tank 721 from the opening at the first sealing sheet 7222. With this design, a small amount of external air 20 can be controlled to enter the tank, so that the foaming liquid 30 can flow out. On the contrary, when the second opening pipe 730 does not deliver water, the self-elastic force or spring force of the third diaphragm 7224 provides a reset force without an applied force, and the first sealing sheet 7222 is sealed, entering an initial untriggered state.
[0066] It should be noted that: In this embodiment 1, the sealed tank body 721 of the foaming liquid storage tank 720 and the hydraulic air supply mechanism 722 cooperate to use the existing water power to control the air supply in the tank, so as to achieve the outflow of the foaming liquid 30 in the tank. The scheme for achieving the above-mentioned effect by cooperating with the sealed tank body 721 and the hydraulic air supply mechanism 722 is not a mandatory implementation scheme of this application. According to the above-mentioned design concept, other structural designs can also be used to realize the delivery of the foaming liquid 30 to the jet mixer 710, including but not limited to the scheme of embodiment 1. In addition, for the hydraulic air supply mechanism 722, those skilled in the art can also use other existing mechanisms to realize the delivery of a small amount of air 20 into the tank to make the foaming liquid 30 flow out, including but not limited to the structural design of the hydraulic air supply mechanism 722 of embodiment 1.
[0067] The present application provides the following preferred operation process example of the hybrid water flushing system of this embodiment 1 for water flushing: like Figure 1-3As shown, the water source inlet end 510 of the water inlet valve mechanism 500 is connected to the municipal tap water waterway, and the incoming water flows into the water tank 100 through the first outlet pipe 520 of the water inlet valve mechanism 500 until the buoy 541 of the first valve structure 540 (buoy 541 limiting device) floats up and closes the waterway. At this time, the water tank 100 has completed water intake.
[0068] like Figure 2 As shown, the first power pump pipe 410 connects the water inlet end of the power pump 400 and the bottom of the water tank 100 to absorb water, the second power pump pipe 420 connects the water outlet end of the power pump 400 to discharge water, and is connected to the reversing mechanism 600, and the circuit switch on the PCB control panel is started to make the power pump 400 work, and water flows to the reversing mechanism 600.
[0069] like Figure 8 As shown, when the reversing mechanism 600 is located at the first initial position, the first outlet 610 is opened, and the water output from the power pump 400 flows directly out of the wash ring from the brushing water delivery pipeline 300 and the wash ring nozzle 310 .
[0070] like Fig. 9 As shown, after a certain period of time T1, the PCB control panel controls the switching mechanism 600 to switch to the second position, and the second outlet 620 is opened, while the first outlet 610 and the scrubbing water delivery pipeline 300 and the wash ring nozzle 310 do not output water. The water output from the power pump 400 flows through the second nozzle water inlet pipe 2412 and the first opening pipe 560. The water in the first opening pipe 560 triggers the second valve structure 550, so that the water in the water inlet valve mechanism 500 flows out to the first nozzle water inlet pipe 2411 through the second outlet pipe 530. Figure 5-7 As shown, the first spray hole 2413 on the nozzle 241 is connected to the first nozzle water inlet pipe 2411, and the second spray hole 2414 is connected to the second nozzle water inlet pipe 2412. The spray holes on the nozzle 241 spray water to flush out the water and dirt in the toilet pit.
[0071] After a period of time T2, when the PCB control panel controls the reversing mechanism 600 to switch back to the first initial position, the first outlet 610 is opened and the second outlet 620 is closed. At this time, water flows out of the wash ring nozzle 310, and no water flows through the first opening tube 560 (at this time, the first spring 552 is reset and the first pressure relief port 554 is resealed). No water flows out of the first nozzle water inlet pipe 2411 and the second nozzle water inlet pipe 2412, and the nozzle 241 does not spray water, thus completing the water seal replenishment of the toilet.
[0072] After flushing is completed, when the water in the water tank 100 drops to a certain position, the float 541 of the first valve structure 540 (the float 541 limiting device) falls, and the first valve structure 540 opens the first water outlet pipe 520 to re-introduce water into the water tank 100 .
[0073] In summary, the hybrid flushing system provided by the present application has the following beneficial effects: The hybrid power flushing system of the present application can use a low-power power pump 400 for washing, and then switch the power water of the power pump 400 to the bottom of the smart toilet for spraying. At the same time, the power water of the power pump 400 triggers the start of tap water with energy to the bottom of the toilet for enhanced spraying through the hydraulic control principle; when the tap water pressure is medium or above, the two-way water channel can be enhanced to spray at the bottom of the toilet body 800, thereby achieving a strong sewage discharge capacity, and the pressure-limiting and pressure-dividing design of the spray outlet can also reduce the noise at high pressure. That is, the flushing system of the present application uses a low-power power pump 400 and external tap water to enhance the spraying, so that the toilet can achieve a stronger sewage discharge effect, can effectively save energy, and can effectively reduce the cost of toilet products.
[0074] In addition, the flushing system can also realize the function of creating a foam shield, and the smart toilet can achieve a stronger sewage discharge effect.
