Figure 1-Figure 5 As shown, the combination valve provided in the embodiment of the present invention comprises:

[0026] A combined valve body 201, and a core solenoid valve 202, a one-way valve 205 and a flushing solenoid valve 207 arranged on the combined valve body 201;

[0027] The combined valve body 201 includes a first end 201a and a second end 201b; the one-way valve 205 in the combined valve body includes a first one-way valve 2053A in the combined valve body and a second one-way valve 2053B in the combined valve body;

[0028] The core solenoid valve 202 and the flushing solenoid valve 207 are arranged in parallel at the second end 201b of the combined valve body 201;

[0029] The one-way valve 205 in the combination valve body is located at the first end of the combination valve body 201 ; the first one-way valve 2053A in the combination valve body is arranged opposite to the movement solenoid valve 202 , and the second one-way valve 2053B in the combination valve body is arranged opposite to the flushing solenoid valve 207 .

[0030] In this embodiment, the combination valve is applied to a smart toilet to control the flow direction of water entering the combination valve body 201. Specifically, the combination valve body 201 includes at least two combination valve sub-cavities. For example, the combination valve body 201 includes a first combination valve sub-cavity and a second combination valve sub-cavity, and a separation structure is provided between the first combination valve sub-cavity and the second combination valve sub-cavity (the separation structure is used to separate the first combination valve sub-cavity and the second combination valve sub-cavity so that the water paths cannot communicate with each other), wherein the outlet end of the movement solenoid valve 202 is located in the first combination valve sub-cavity (that is, it is ensured that the movement solenoid valve 202 is in the open state and when water enters the inlet end of the movement solenoid valve 202, water can flow from the outlet end of the movement solenoid valve 202 into the first combination valve sub-cavity); the outlet end of the flushing solenoid valve 207 is located in the second combination valve sub-cavity (that is, it is ensured that the flushing solenoid valve 207 is in the open state and when water enters the inlet end of the flushing solenoid valve 207, water can flow from the outlet end of the flushing solenoid valve 207 into the second combination valve sub-cavity).

[0031] The combination valve body 201 is also provided with a first outlet of the combination valve body and a second outlet of the combination valve body; the first outlet of the combination valve body is provided on the first combination valve sub-cavity, and the second outlet of the combination valve body is provided on the second combination valve sub-cavity. For example, the core solenoid valve 202 can be opened to control the water flow to the water path where the core solenoid valve 202 is located (specifically, it can flow in the first combination valve sub-cavity and flow to the first outlet of the combination valve body); the flushing solenoid valve 207 can also be opened to control the water flow to the water path where the flushing solenoid valve 207 is located (specifically, it can flow in the second combination valve sub-cavity and flow to the second outlet of the combination valve body).

[0032] The first outlet of the combination valve body and the second outlet of the combination valve body can be connected to different devices respectively to control the flow direction of water. For example, the first outlet of the combination valve body is connected to a ceramic water diverter valve 206, and the second outlet of the combination valve body is connected to a flush check valve 208.

[0033] In one embodiment, if Figure 1-Figure 5 As shown, the combination valve further includes at least one combination valve pressure reducing valve arranged on the combination valve body 201 .

[0034] In a specific application scenario, such as Figure 1-Figure 5 As shown, the combination valve pressure reducing valve includes a core pressure reducing valve 203 disposed on the combination valve body 201, and / or a pressure reducing valve 209 connected to the second end of the combination valve body 201. That is, the combination valve pressure reducing valve has at least 3 specific implementations, as follows:

[0035] 1) The combination valve pressure reducing valve comprises a core pressure reducing valve 203 arranged on the combination valve body 201; wherein the core pressure reducing valve 203 is located on a side of the core solenoid valve 202 away from the second end;

[0036] 2) The combination valve pressure reducing valve includes a pressure reducing valve 209 connected to the second end of the combination valve body 201;

[0037] 3) The combination valve pressure reducing valve comprises a movement pressure reducing valve 203 arranged on the combination valve body 201, and a pressure reducing valve 209 connected to the second end of the combination valve body 201; wherein, the movement pressure reducing valve 203 is located on the side of the movement solenoid valve 202 away from the second end.

[0038] That is, in a water path corresponding to the core solenoid valve 202, the pressure may be stabilized by the pressure reducing valve 209 connected to the second end of the combination valve body 201 before water enters the core solenoid valve 202, or the pressure may be stabilized by the core pressure reducing valve 203 after water enters the core solenoid valve 202. Alternatively, the combination valve pressure reducing valve includes the core pressure reducing valve 203 and the pressure reducing valve 209, and the pressure is stabilized for the first time by the pressure reducing valve 209 connected to the second end of the combination valve body 201 before water enters the core solenoid valve 202, and then the pressure is stabilized for the second time by the core pressure reducing valve 203 after water enters the core solenoid valve 202.

[0039] In one embodiment, if Figure 1 As shown, the combination valve further includes a core check valve 204 and a flush check valve 208 disposed on the combination valve body 201;

[0040] The one-way valve 204 is located at a side of the pressure reducing valve 203 away from the second end 201b.

[0041] The flushing check valve 208 is located at a side of the flushing solenoid valve 207 away from the second end 201 b.

[0042] In this embodiment, the combination valve is further provided with the core check valve 204, the outlet end of which can be connected to the first outlet of the combination valve body, in order to prevent the water from flowing back through the core check valve 204 and flowing to the next position, thereby causing pollution to the waterway before the inlet end of the core check valve 204. Similarly, the combination valve is further provided with the flush check valve 208, the outlet end of which can be connected to the second outlet of the combination valve body, in order to prevent the water from flowing back through the flush check valve 208 and flowing to the next position, thereby causing pollution to the waterway before the inlet end of the flush check valve 208.

[0043] For example, when the core solenoid valve 202 and the flushing solenoid valve 207 of the combination valve are both connected to the tap water network, the core one-way valve 204 and the flushing one-way valve 208 are provided to effectively prevent sewage from flowing back and polluting the tap water network.

[0044] In a specific implementation, only one of the movement check valve 204 and the flushing check valve 208 can be selected and set at the corresponding position. For example, when the movement check valve 204 is selected, the movement check valve 204 is located on the side of the movement pressure reducing valve 203 away from the second end. If the flushing check valve 208 is selected, the flushing check valve 208 is located on the side of the flushing solenoid valve 207 away from the second end.

[0045] In one embodiment, if Figure 1 As shown, the combination valve further includes a ceramic water diversion valve 206 disposed on the combination valve body 201;

[0046] The ceramic water diverter valve 206 is located on a side of the core one-way valve 204 close to the first end 201 a.

[0047] In this embodiment, the ceramic water diverter valve 206 is further provided on the combination valve, and the ceramic water diverter valve 206 can be specifically connected to the first outlet of the combination valve body. When water flows through the movement solenoid valve 202, the movement pressure reducing valve 203, and the movement check valve 204 in sequence and flows into the ceramic water diverter valve 206, the ceramic water diverter valve 206 can be connected to multiple next devices (such as a steam box in a smart toilet, etc.), so that the ceramic water diverter valve 206 can supply water in multiple waterways.

[0048] In one embodiment, if Figure 1-5 As shown, as a preferred embodiment of the combination valve, the combination valve includes:

[0049] A combined valve body 201, and a core solenoid valve 202, a one-way valve 205 and a flushing solenoid valve 207 arranged on the combined valve body 201;

[0050] It also includes a core pressure reducing valve 203 disposed on the combined valve body 201, and a pressure reducing valve 209 connected to the second end 201b of the combined valve body 201;

[0051] It also includes a core check valve 204 and a flush check valve 208 disposed on the combined valve body 201;

[0052] It also includes a ceramic water diversion valve 206 disposed on the combined valve body 201;

[0053] The combined valve body 201 includes a first end 201a and a second end 201b; the one-way valve 205 in the combined valve body includes a first one-way valve 2053A in the combined valve body and a second one-way valve 2053B in the combined valve body;

[0054] The core solenoid valve 202 and the flushing solenoid valve 207 are arranged in parallel at the second end 201b of the combined valve body 201;

[0055] The one-way valve 205 in the combination valve body is located at the first end 201a of the combination valve body 201; the first one-way valve 2053A in the combination valve body is arranged opposite to the core solenoid valve 202, and the second one-way valve 2053B in the combination valve body is arranged opposite to the flushing solenoid valve 207;

[0056] The movement pressure reducing valve 203 is located at a side of the movement solenoid valve 202 away from the second end 201b;

[0057] The core one-way valve 204 is located at a side of the core pressure reducing valve 203 away from the second end 201b;

[0058] The flushing check valve 208 is located at a side of the flushing solenoid valve 207 away from the second end 201b;

[0059] The ceramic water diversion valve 206 is located on a side of the core one-way valve 204 close to the first end 201 a.

[0060] In a specific application scenario, a first pipeline 2011 of the combined valve body 201 is provided at the second end 201b of the combined valve body 201, and the first pipeline 2011 of the combined valve is connected to one end of the movement solenoid valve 202 and one end of the flushing solenoid valve 207;

[0061] The other end of the flushing solenoid valve 207 is connected to the second valve 2053B of the combination valve body of the one-way valve 205 in the combination valve body through the second combination valve pipeline 2012;

[0062] The second valve 2053B of the one-way valve in the combination valve body 205 of the combination valve body is also connected to one end of the flushing one-way valve 208 through the third pipeline 213 of the combination valve;

[0063] The other end of the movement solenoid valve 202 is connected to one end of the movement pressure reducing valve 203 through the fourth pipeline 2014 of the combination valve;

[0064] The other end of the movement pressure reducing valve 203 is connected to the first valve 2053A of the combination valve body check valve 205 of the combination valve body through the fifth combination valve pipeline 2015;

[0065] The one-way valve 205 in the combination valve body is also connected to one end of the one-way valve 204 of the core through the sixth pipeline 2016 of the combination valve;

[0066] The other end of the core check valve 204 is connected to the ceramic water diversion valve 206 through the seventh pipeline of the combination valve (not shown in the figure);

[0067] The other end of the flushing check valve 208 is also connected to an eighth pipeline of the combined valve for water outlet (not shown in the figure);

[0068] The other end of the ceramic water diversion valve 206 is also connected to a ninth pipeline of the combined valve for discharging water (not shown in the figure).

[0069] In this embodiment, the second end 201b of the combination valve body 201 may also be connected to a pressure reducing valve 209. After water enters the pressure reducing valve 209 (for example, tap water flows into the water inlet pipe of the ceramic body of the toilet), it enters the combination valve first pipe 2011 in the combination valve body 201. Since the combination valve first pipe 2011 is connected to one end of the core solenoid valve 202 and one end of the flushing solenoid valve 207, when only one of the core solenoid valve 202 or the flushing solenoid valve 207 is opened, the water in the combination valve first pipe 2011 flows to the core solenoid valve 202 or the flushing solenoid valve 207 that is in the opened state. If both the core solenoid valve 202 and the flushing solenoid valve 207 are opened, the water in the combination valve first pipe 2011 flows to the core solenoid valve 202 and the flushing solenoid valve 207, respectively.

[0070] In a specific application scenario, if the movement solenoid valve 202 is open and the flushing solenoid valve 207 is closed, water flows into the movement pressure reducing valve 203 through the movement solenoid valve 202, and the water flows into the ceramic water diversion valve 206 through the one-way valve 205 in the combined valve body and the movement one-way valve 204 after being stabilized by the movement pressure reducing valve 203;

[0071] If the flushing solenoid valve 207 is opened and the core solenoid valve 202 is closed, water flows to the flushing one-way valve 208 after passing through the one-way valve 205 in the combined valve body;

[0072] If the movement solenoid valve 202 and the flushing solenoid valve 207 are both opened, water flows into the movement pressure reducing valve 203 through the movement solenoid valve 202. After being stabilized by the movement pressure reducing valve 203, the water passes through the one-way valve 205 in the combination valve body and the movement one-way valve 204 in turn and flows into the ceramic water diversion valve 206; at the same time, the water flows to the flushing one-way valve 208 after passing through the one-way valve 205 in the combination valve body.

[0073] In this embodiment, when only the movement solenoid valve 202 is opened (that is, the movement solenoid valve 202 is opened and the flushing solenoid valve 207 is closed), water first flows into the movement pressure reducing valve 203 through the movement solenoid valve 202, and then the water is stabilized in the movement pressure reducing valve 203, and then flows to the movement one-way valve 204 through the one-way valve 205 in the combination valve body, and then the water flows to the ceramic water diversion valve 206 after being diverted by the movement one-way valve 204, and finally flows to the next component connected to the ceramic water diversion valve 206 (specifically, such as the steam box in the smart toilet).

[0074] When only the flush solenoid valve 207 is opened (i.e., the flush solenoid valve 207 is opened and the movement solenoid valve 202 is closed), water flows through the second pipe 2012 of the combination valve to the one-way valve 205 in the combination valve body, and then the water flows through the third pipe 2013 of the combination valve to the flush one-way valve 208, and finally flows to the next component connected to the flush one-way valve 208 (specifically, such as the water tank in the smart toilet).

[0075] When the core solenoid valve 202 and the flush solenoid valve 207 are both opened, the water flow direction is a combination of the above two situations, that is, the water in the two branches will flow. Through this structure of the combined valve, it is realized that the corresponding solenoid valve is selectively opened according to the water demand of other functional components (such as the steam box and the water tank) in the intelligent toilet.

[0076] In one embodiment, if Figure 1 , Figure 3 , Figure 4a , Figure 4b and Figure 5 As shown, as the first embodiment of the one-way valve 205 in the combination valve body, the one-way valve 205 in the combination valve body is a vacuum explosion structure; the vacuum explosion structure includes:

[0077] Vacuum bursting diaphragm 2051;

[0078] A vacuum bursting diaphragm valve 2053 having one end flexibly connected to the vacuum bursting diaphragm 2051;

[0079] and an air inlet disposed on the combined valve body 201 and adapted to the vacuum bursting diaphragm valve 2053; the number of the air inlets is greater than or equal to 2;

[0080] If the vacuum bursting diaphragm valve 2053 is subjected to positive pressure, the vacuum bursting diaphragm valve 2053 closes the air inlet; if the vacuum bursting diaphragm valve 2053 is subjected to negative pressure, the vacuum bursting diaphragm valve 2053 is separated from the air inlet.

[0081] In a specific application scenario, such as Figure 3 , Figure 4a, Figure 4b and Figure 5 As shown, the vacuum bursting diaphragm 2051 is provided with two air inlets, which are respectively denoted as the first air inlet 2052A of the vacuum bursting diaphragm and the second air inlet 2052B of the vacuum bursting diaphragm. The number of the vacuum bursting diaphragm valves 2053 is two, which are respectively denoted as the first check valve 2053A of the combination valve body and the second check valve 2053B of the combination valve body. The first check valve 2053A of the combination valve body is connected to the vacuum bursting diaphragm 2051 through the first deformed thin wall 2054A, and the second check valve 2053B of the combination valve body is connected to the vacuum bursting diaphragm 2051 through the second deformed thin wall 2054B.

[0082] During specific implementation, the first one-way valve 2053A in the combination valve body is aligned with the fifth pipeline 2015 of the combination valve, and the second one-way valve 2053B in the combination valve body is aligned with the second pipeline 2012 of the combination valve.

[0083] In this embodiment, when negative pressure is generated in the fifth pipeline 2015 of the combination valve, the first deformed thin wall 2054A between the first valve 2053A of the one-way valve in the combination valve body and the vacuum bursting diaphragm 2051 is bent and deformed due to the negative pressure, and the first valve 2053A of the one-way valve in the combination valve body is separated from the first air inlet 2052A of the vacuum bursting diaphragm, so that the first air inlet 2052A of the vacuum bursting diaphragm is in an open state, and air enters from the first air inlet 2052A of the vacuum bursting diaphragm, which has a bursting effect.

[0084] Similarly, when negative pressure is generated in the second pipeline 2012 of the combination valve, the second deformed thin wall 2054B between the second valve 2053B of the one-way valve in the combination valve body and the vacuum bursting diaphragm 2051 is bent and deformed due to the negative pressure, and the second valve 2053B of the one-way valve in the combination valve body is separated from the second air inlet 2052B of the vacuum bursting diaphragm, so that the second air inlet 2052B of the vacuum bursting diaphragm is in an open state, and air enters from the second air inlet 2052B of the vacuum bursting diaphragm, achieving a bursting effect.

[0085] When implementing it, Figure 1 , Figure 4a , Figure 4b and Figure 5 As shown, the first one-way valve 2053A and the second one-way valve 2053B of the combination valve body are both arranged on the side of the vacuum bursting diaphragm 2051 close to the second end 201b, which can effectively prevent the first one-way valve 2053A and the second one-way valve 2053B of the combination valve body from being opened when water flows, thereby causing water leakage.

[0086] In one embodiment, if Figure 6 As shown, as a second embodiment of the one-way valve in the combination valve body, the one-way valve in the combination valve body is a negative pressure destructive check valve; the negative pressure destructive check valve comprises a valve core 205b, the valve core 205b is arranged near the first end of the combination valve body, the valve core 205b has a radially outwardly expanded middle diaphragm 205f, a spring 205c is arranged between the middle diaphragm 205f and the vent 205a, a second sealing gasket 205e is arranged on the side of the middle diaphragm 205f close to the spring 205c, and a first sealing gasket 205d is arranged on the side of the middle diaphragm 205f away from the spring 205c. When the first sealing gasket 205d contacts the middle diaphragm 205f, water can be prevented from flowing out of the valve core 205b through the middle diaphragm 205f. When the second sealing gasket 205e contacts the middle partition plate 205f, it can prevent water from flowing from the middle of the upper end of the valve core 205b into another valve seat to which the valve core 205b is connected.

[0087] The check and negative pressure destroying function of the negative pressure destructive check valve is that when negative pressure is generated on one side of the vent 205a, the valve core 205b is pushed to move under the combined action of the spring 205c and the vent 205a, and the first sealing gasket 205d is pressed on the valve seat A at the middle diaphragm 205f, so that water cannot flow out of the valve core 205b from the middle diaphragm 205f; when the first sealing gasket 205d is not pressed on the valve seat A at the middle diaphragm 205f and the seal fails, air enters through the vent 205a and the valve seat A, destroying the negative pressure on the side of the valve seat A close to the middle diaphragm 205f, thereby achieving the effect of negative pressure destruction.

[0088] In one embodiment, if Figure 1 , Figure 2a , Figure 7a and Figure 7b As shown, the movement check valve 204 includes a movement check valve cavity 2041, a movement check valve support 2042 and a movement check valve sealing ring 2043 which are sequentially arranged in the movement check valve cavity, and also includes a movement check valve cover 2044 which is arranged at the outlet of the movement check valve cavity;

[0089] The movement one-way valve sealing ring 2043 is sleeved on one end of the movement one-way valve bracket 2042 .

[0090] In this embodiment, the water in the core check valve 204 can only be discharged according to the arrow (such as Figure 7b It is essentially a one-way valve to prevent water from flowing in the reverse direction.

[0091] In a specific application scenario, the movement check valve support 2042 includes a movement check valve water inlet baffle plate 20421 and a movement check valve water inlet baffle column 20422 connected to the rear end of the movement check valve water inlet baffle plate, one end of the movement check valve water inlet baffle plate 20421 is pressed against the periphery of the movement check valve cavity 2041 near one end of the flushing solenoid valve; wherein the movement check valve sealing ring 2043 is sleeved in the movement check valve support and pressed against the movement check valve cavity near one end of the flushing solenoid valve. The movement check valve 204 also includes a movement check valve spring 2045 sleeved on the movement check valve water inlet baffle column 20422.

[0092] More specifically, a core check valve water inlet mounting column 20423 is provided in the core check valve bracket 2042 near one end of the flushing solenoid valve, and the core check valve sealing ring 2043 is sleeved on the core check valve water inlet mounting column 20423 .

[0093] That is, if the movement solenoid valve 202 is opened and the flushing solenoid valve 207 is closed, water flows into the movement pressure reducing valve 203 through the movement solenoid valve 202, and after the water is stabilized by the movement pressure reducing valve 203, it passes through the one-way valve 205 in the combined valve body and the movement one-way valve 204 in turn and flows into the ceramic water diversion valve 206. During this flushing process, when water flows into the movement one-way valve cavity 2041, it will apply an upward force to the movement one-way valve water inlet baffle 20421, and use the movement one-way valve water inlet baffle 20421 to compress the movement one-way valve spring 2045, so that a gap is generated around the movement one-way valve water inlet baffle 20421 and the movement one-way valve cavity 2041, so that water flows out from one end of the movement one-way valve cover 2044.

[0094] If water flows back from the one-way valve cover 2044 into the one-way valve cavity 2041 (such as Figure 7b The reverse flow of water presses the sealing ring 2043 of the movement check valve against the side wall of the movement check valve cavity 2041, thereby preventing the water from flowing back into the combination valve body 201 and contaminating the combination valve body 201 and the valves disposed therein.

[0095] In one embodiment, if Figure 1 , Figure 2a , Figure 8 As shown, the flushing check valve 208 includes a flushing check valve cavity 2081, and a flushing check valve bracket 2082 and a flushing check valve sealing ring 2083 which are sequentially arranged in the flushing check valve cavity 2081, and also includes a flushing check valve pipe 2084 arranged on the flushing check valve cavity 2081;

[0096] The flushing check valve sealing ring 2083 is sleeved on one end of the flushing check valve bracket 2082 close to the flushing solenoid valve 207;

[0097] The flushing one-way valve connecting pipe 2084 is located at an end of the flushing one-way valve bracket away from the flushing solenoid valve 207 .

[0098] In this embodiment, the water in the flush check valve 208 can only be flushed according to the arrow (such as Figure 8 The flush check valve 208 is essentially a one-way valve to prevent water from flowing in the reverse direction. The structure of the flush check valve 208 is the same as that of the core check valve 204, except that the flush check valve pipe 2084 and the core check valve cover 2044 are different, and the other structures and the principle of preventing water from flowing in the reverse direction are also the same.

[0099] That is, if water flows back from the flush check valve pipe 2084 into the flush check valve cavity 2081 (such as Figure 8 ), the reverse flow water presses the flushing check valve sealing ring 2083 against the side wall of the flushing check valve cavity 2081, preventing water from flowing back into the combination valve body 201 and contaminating the combination valve body 201 and the valves arranged therein.

[0100] The embodiment of the present invention further provides an intelligent toilet, comprising the above-mentioned combination valve. By arranging the combination valve with a simplified structure in the intelligent toilet, water flow pressure loss can be effectively avoided.
