Description

Technical Field

[0001] The invention relates to bathroom technology, in particular to a mixing flush valve, a toilet flushing system and a toilet. Background Art

[0002] At present, the water tank of smart toilets generally adopts low water tanks, resulting in low water potential energy in the water tank. Therefore, flushing with the potential energy of the water in the water tank alone will affect the flushing effect. For this reason, the current flushing method using a booster pump pressurizes the water from the water tank and then outputs it. However, the operating power of the booster pump is relatively large. When there is a power outage, the built-in supercapacitor cannot be used and needs to be driven by an external larger battery, which is more troublesome to use and more expensive.

[0025] like Figure 1-Figure 9 As shown, an embodiment of the present application provides a mixing flush valve 100 , including a valve body 1 , a floating member 2 provided on the valve body 1 , and a first water channel switching mechanism 3 .

[0026] like Figure 3As shown, the valve body 1 is provided with an inner cavity, which includes a first water inlet channel 11 and a second water inlet channel 12, a brush ring channel 13 and a spray channel 14. The first water channel switching mechanism 3 is provided on the valve body 1, and is configured to control the opening and closing of the brush ring channel 13 and the spray channel 14 with the first water inlet channel 11 or the second water inlet channel 12. The water inlet end of the first water inlet channel 11 is configured to be connected to a municipal water source (tap water), and the second water inlet channel 12 is configured to be connected to pressurized water.

[0027] The floating member 2 isolates the first water inlet channel 11 and the second water inlet channel 12, and can move in the inner cavity under the change of the water inlet pressure difference between the first water inlet channel 11 and the second water inlet channel 12 to switch between a first working state of blocking the first water inlet channel 11 and a second working state of blocking the second water inlet channel 12.

[0028] The two-way water inlet and two-way water outlet provided by the mixed flush valve 100 are distributed through the floating member 2 and the first water channel switching structure 3 to achieve multiple water outlet modes. At the same time, the water inlet waterway is distributed by setting a floating member 7 that can move under the change of the water inlet pressure difference to achieve water channel distribution in the first water inlet channel 11 and the second water inlet channel 12, so that there is no need to use mechanical or electric control valves and other components, which can reduce the overall volume of the valve body, reduce noise and the number of control mechanisms or design complexity, and ensure that the water inlet waterway can be switched in the power-off state. Furthermore, the floating member 2 isolates the first water inlet channel 11 and the second water inlet channel 12, which can prevent the water flow in the first water inlet channel 11 and the second water inlet channel 12 from flowing in series.

[0029] When the mixed flush valve 100 is used in conjunction with the booster pump 200 to flush the toilet 300, the mixed flush valve 100 can realize two flushing water paths of booster flushing and tap water flushing. Therefore, when the booster pump 200 fails to work due to power outages or other factors, the toilet 300 can still be flushed using the flushing water path of tap water, ensuring that the toilet 300 has at least one function of normal flushing and brushing.

[0030] like Figure 3 , Figure 4 As shown, the inner cavity of the mixing flush valve 100 includes a first distribution water cavity 101 and a second distribution water cavity 102, and a switching channel 15 connecting the first distribution water cavity 101 and the second distribution water cavity 102. The first water inlet channel 11 and the second water inlet channel 12 are respectively connected to the first distribution water cavity 101, and the floating member 2 is movably arranged in the first distribution water cavity 101 and is configured to control the opening and closing of the first water inlet channel 11 and the second water inlet channel 12. The first water path switching mechanism 3 is installed in cooperation with the second distribution water cavity 102, and is configured to control the opening and closing of the first water inlet channel 11 and the second water inlet channel 12.

[0031] like Figure 2As shown, the first water channel switching mechanism 3 can be a drive motor control valve, an electromagnetic control valve or a pilot electromagnetic valve. Taking the drive motor control valve as an example, it includes a blocking member 30 provided in the second water distribution chamber 102, and a drive motor 31 connected to the blocking member 30. The drive motor 31 can drive the blocking member 30 to move so that the blocking member 30 switches between a first action state of blocking the brush ring flow channel 13 and a second action state of blocking the spray flow channel 14.

[0032] like Figure 4 As shown, the outlet port of the switching channel 15, the brush ring channel 13, and the spray channel 14 are arranged along the circumference of the first water distribution chamber 101. The blocking member 30 is a gate, and can rotate under the drive of the driving motor 31 to switch between the first action state and the second action state.

[0033] like Figure 3-Figure 6 As shown, the floating member 2 in this embodiment includes a disc 20 and a column 21, and the column 202 is composed of a plurality of blades. The first water distribution chamber 101 is provided with a first stopper 1013 and a second stopper 1014. The two ends of the floating member 2 are respectively stopped by the first stopper 1013 and the second stopper 1014 in the first working state and the second working state, and the first stopper 1013 and the second stopper 1014 are arranged at the two ends of the first water distribution chamber 101 along the water flow direction. The floating member 2 in this embodiment adopts a bidirectional non-return column to achieve a higher non-return effect.

[0034] like Figure 2 As shown, the valve body 1a includes a shell body 10a and a joint 11a installed on the shell body 10a, and the second water inlet flow channel 12 is formed by the joint 11a. The lower end of the shell body 10a is provided with an interface for installing the joint 11a, and the joint 11a is installed on the shell body 10a through the interface. The first stopper 1013 is formed by the end of the joint, and the floating member 2 moves between the first stopper 1013 and the second stopper 1014.

[0035] The first stopper 1013 of the first water distribution chamber 101 has a through hole (see Figure 3 , Figure 6 The floating member 2 passes through the position (not numbered), and the column 202 of the floating member 2 passes through the through hole. When the first water inlet channel 11 and the second water inlet channel 12 are switched, the through hole is used to guide the column 202 to slide, thereby increasing the stability of the activity.

[0036] like Figure 2As shown, the valve body 1 includes a first valve body 1a, a valve cover 1b and a second valve body 1c. The first valve body 1a is provided with an open end at one end along the longitudinal direction, and the valve cover 1b cooperates with the first valve body 1a to cover and shield the open end. The first valve body 1a and the valve cover 1b together enclose a first water inlet channel 11, a second water inlet channel 12 and a first distribution water chamber 101. The first valve body 1a and the valve cover 1b are detachably connected by connecting bolts. The first valve body 1a is provided with an interface end at one end along the transverse direction, and the second valve body 1c is connected to the interface end of the first valve body 1a. The second valve body 1c and the first valve body 1a together form a brush ring channel 13, a spray channel 14, a transfer channel 15 and a second distribution water chamber 10.

[0037] The first water inlet channel 11 , the second water inlet channel 12 and the first distribution water chamber 101 extend vertically. The first water inlet channel 11 is arranged side by side with the second water inlet channel 12 and the first distribution water chamber 101 , and the first distribution water chamber 101 is arranged downstream of the second water inlet channel 12 .

[0038] The mixing flush valve 100 arranges the first water inlet channel 11 and the second water inlet channel 12 and the first distribution water chamber 101 side by side, and the second water inlet channel 12 and the first distribution water chamber 101 are arranged in the same row, so that the valve body 1 has a compact structure, a small overall volume, and occupies less space. In addition, the first valve body 1a and the valve cover 1b are designed to be assembled, which can facilitate the installation of the anti-siphon member 4 and the floating member 2. Of course, the valve body 1 can also be integrally formed, which can reduce the number of parts and assembly structures.

[0039] A portion of the open end of the first valve body 1a forms the water outlet port of the first water inlet channel 11, and the other portion forms the connecting port between the first distribution chamber 101 and the first water inlet channel 11. The mixed flush valve 100 of this embodiment also includes an anti-siphon component 4 provided at the water outlet port of the first water inlet channel 11, and the anti-siphon component 4 is installed on the valve cover 1b. When water enters the second water inlet channel 12, the water flow pushes open the anti-siphon component 4 and opens the water outlet port of the first water inlet channel 11. When the water pressure in the second water inlet channel 12 disappears or the second water supply channel 17 generates negative pressure, the floating component 2 blocks the second water inlet channel 12, and the anti-siphon component 4 blocks the water outlet port 170 of the first water inlet channel 11 (see FIG. 1 ). Figure 6 ), to prevent water from flowing back into the first water inlet channel 11.

[0040] The mixing flush valve 100 can prevent the first water supply channel 16 from being connected to the second distribution water chamber 102 by setting an anti-siphon member 4, so that water flows back from the second distribution water chamber 102 to the first water inlet channel 11 and flows back to the water tank 400 through the first water supply channel 16, causing pollution to the water in the water tank.

[0041] The mixing flush valve 100 arranges the first water inlet channel 11, the second water inlet channel 12 and the first distribution water chamber 101 side by side, and sets the second water inlet channel 12 and the first distribution water chamber 101 in the same row, thereby saving overall space and having a compact structure.

[0042] like Figure 1 , Figure 3 As shown, the mixing flushing valve 1 also includes a first water supply channel 16 connected to the second water inlet channel 12, and a second water path switching mechanism 5 that controls the on-off of the first water supply channel 16 and the second water inlet channel 12. The second water path switching mechanism 5 can be a mechanical control valve, an electromagnetic control valve or a pilot electromagnetic valve. Taking the pilot electromagnetic valve as an example, when the floating member 2 is in the first working state, the first water inlet channel 11 and the first water supply channel 16 are blocked; when the floating member 2 is in the second working state, the first water inlet channel 11 and the first water supply channel 16 are connected.

[0043] like Figure 1 , Figure 3 As shown, the mixing flush valve 1 further includes a second water supply channel 17, which is connected to the water inlet end of the first water supply channel 16. The second water supply channel 17 is always connected to the first water supply channel 16 to replenish water for the water tank 400. like Figure 3-Figure 5 As shown, when flushing with the first flushing waterway, water enters the first water inlet channel 11, and the water flow pushes the floating member 2 to move and connect the first water inlet channel 11 with the first distribution water chamber 101. The water flows into the first distribution water chamber 101 and flows into the second distribution water chamber 102 from the switching channel 15. The driving motor 31 drives the blocking member 30 to rotate to the first action state, blocking the brush ring channel 13, and the water flows out from the spraying channel 14, so that the toilet can be brushed. After the brushing is completed, the driving motor 31 drives the blocking member 30 to rotate to the second action state, blocking the spraying channel 14, and the water flows out from the brush ring channel 13, so that the toilet can be sprayed and flushed.

[0044] like Figure 6-Figure 8 As shown, when flushing with the second flushing waterway, water enters the second water inlet channel 12, and the water flow pushes the anti-siphon member 4 to open the water outlet port of the first water inlet channel, pushing the floating member 2 to move, connecting the second water inlet channel 12 with the first distribution water chamber 101, and the water flows into the first distribution water chamber 101 and flows into the second distribution water chamber 102 from the transfer channel 15. The driving motor 31 drives the blocking member 30 to rotate to the first action state, blocking the brush ring channel 13, and the water flows out from the spraying channel 14, so that the brushing of the toilet 300 can be performed. After the brushing is completed, the driving motor 31 drives the blocking member 30 to rotate to the second action state, blocking the spraying channel 14, and the water flows out from the brush ring channel 13, so that the spraying flushing of the toilet 300 can be performed.

[0045] like Fig. 9 , Fig.10 As shown, the embodiment of the present application also provides a toilet flushing system, comprising: a booster pump 200, a water tank 400, and a mixed flushing valve 100 as described in any of the above embodiments. The water inlet end of the booster pump 200 is connected to the water tank 400, and the water outlet end of the booster pump 200 is connected to the first water inlet flow channel 11 of the mixed flushing valve 100. The brush ring flow channel 13 and the spray flow channel 14 of the mixed flushing valve 100 are arranged to be respectively connected to the spray interface (not shown) and the brush ring interface (not shown) of the toilet 300.

[0046] In an exemplary embodiment, the mixing flush valve 100 further includes an energy storage power supply (not shown) connected to the first water circuit switching mechanism 3 and the second water circuit switching mechanism 5. The energy storage power supply is configured to supply power to the first water circuit switching mechanism 3 and the second water circuit switching mechanism 5 of the mixing flush valve 100 when a power outage occurs.

[0047] Since the first water circuit switching mechanism 2 of the embodiment of the present application adopts a drive motor control valve and is combined with a non-power-consuming floating part 2 for water inlet circuit distribution, the structural design is simple, and in a power outage state, it can still ensure that one water supply circuit is open to ensure water supply to the downstream flushing or brush ring, so that the flushing function of the toilet can be guaranteed even in a power-off state.

[0048] In addition, the floating member 2 does not consume energy and the blocking member 30 will not be unable to open due to excessive water pressure. Furthermore, the embodiment of the present application is equipped with an anti-siphon member 4 for a water inlet waterway (tap water inlet waterway), which can not only prevent siphoning, but also prevent the problem of difficulty in opening the first waterway switching mechanism 3 due to the effect of water pressure, reduce the power consumption of the first waterway switching mechanism 3, and further reduce the capacity of the energy storage power supply.

[0049] like Fig. 9 , Fig.10 As shown, the embodiment of the present application further provides a toilet, comprising: a toilet body having a spray interface and a brush ring interface (not shown), and a toilet flushing system as described in any of the above embodiments assembled with the toilet body. Among them, the first water inlet flow channel 11 of the mixed flushing valve 100 of the toilet flushing system is configured to be connected to the booster pump 200 to provide pressurized water; the second water inlet flow channel 12 is configured to be connected to a municipal water source (tap water source); the brush ring flow channel 13 and the spray flow channel 14 of the mixed flushing valve 100 are respectively connected to the spray interface and the brush ring interface.

[0050] When in the power-on state, water enters the first water inlet channel 11, and the booster pump 200 draws water from the water tank 400 into the mixing flush valve 100 to distribute water, and the toilet 300 is brushed and sprayed.

[0051] When in a power-off state, the energy storage power supply supplies power to the first water circuit switching mechanism 3 and the second water circuit switching mechanism 5 of the mixed flushing valve 100. The first water circuit switching mechanism opens the second water inlet channel 12 to let water in, enters the mixed flushing valve 100 to distribute the water, and performs brushing and spraying on the toilet 300. At the same time, the water in the second water inlet channel 12 enters the water tank 400 through the third water outlet 20 to replenish the water tank 400. Of course, in the absence of an energy storage power supply, the mixed flushing valve 100 of the embodiment of the present application can at least ensure that one of the brushing and spraying can be used.
