Wherein, the combined valve body 201 is also provided with a first combined valve body outlet and a second combined valve body outlet; the first outlet of the combined valve body is arranged on the first combined valve cavity, and the second outlet of the combined valve body is arranged on the second combined valve cavity.

wherein, the core electromagnetic valve 202 and the flushing electromagnetic valve 207 are arranged in parallel at the second end 201b of the combined valve body 201;

the combination valve body inner check valve 205 is located at the first end 201a of the combination valve body 201; the first valve 2053A of the check valve in the combined valve body is arranged opposite to the core electromagnetic valve 202, and the second valve 2053B of the check valve in the combined valve body is arranged opposite to the flushing electromagnetic valve 207;

the core pressure reducing valve 203 is positioned on one side of the core electromagnetic valve 202 away from the second end 201 b;

the movement check valve 204 is positioned on one side of the movement pressure reducing valve 203 far away from the second end 201 b;

In a specific application scenario, a first combination valve pipeline 2011 is arranged at the second end 201b of the combination valve body 201, and the first combination valve pipeline 2011 is connected with one end of the movement electromagnetic valve 202 and one end of the flushing electromagnetic valve 207;

the other end of the flushing solenoid valve 207 is connected to the second combined valve body check valve 2053B of the combined valve body check valve 205 through a second combined valve pipe 2012;

the second combined valve 2053B of the combined valve body internal check valve 205 is further connected with one end of the flushing check valve 208 through a third combined valve pipe 2013;

the other end of the movement electromagnetic valve 202 is connected with one end of the movement pressure reducing valve 203 through a fourth pipeline 2014 of the combination valve;

the other end of the movement pressure reducing valve 203 is connected with a first combination valve body inner check valve 2053A of the combination valve body inner check valve 205 through a combination valve fifth pipeline 2015;

the combination valve body inner check valve 205 is further connected with one end of the movement check valve 204 through a combination valve sixth pipeline 2016;

the other end of the movement check valve 204 is connected with the ceramic shunt valve 206 through a seventh pipeline of the combination valve (not shown in the figure);

the other end of the flushing check valve 208 is also connected with an eighth pipeline (not shown in the figure) of a combined valve for water outlet;

the other end of the ceramic shunt valve 206 is also connected with a ninth pipeline (not shown in the figure) of a combination valve for water outlet.

In this embodiment, the second end 201b of the combination valve body 201 may further be connected with a pressure reducing valve 209, and after water enters the pressure reducing valve 209 (for example, tap water flows into a water inlet pipe in a ceramic body of the toilet), the water enters a first pipe 2011 of the combination valve in the combination valve body 201. Since the first conduit 2011 of the combination valve is connected to both one end of the core solenoid valve 202 and one end of the flush solenoid valve 207, when only one of the core solenoid valve 202 or the flush solenoid valve 207 is opened, the water in the first conduit 2011 of the combination valve flows to the solenoid valve in the open state in the core solenoid valve 202 or the flush solenoid valve 207. If both of the core solenoid valve 202 and the flush solenoid valve 207 are open, water in the first conduit 2011 of the combination valve flows to the core solenoid valve 202 and the flush solenoid valve 207, respectively.

In a specific application scenario, if the core electromagnetic valve 202 is opened and the flush electromagnetic valve 207 is closed, water flows into the core pressure reducing valve 203 through the core electromagnetic valve 202, and the water is subjected to pressure stabilization through the core pressure reducing valve 203 and then flows into the ceramic water diversion valve 206 through the combination valve body internal check valve 205 and the core check valve 204 in sequence;

if the flushing solenoid valve 207 is opened and the core solenoid valve 202 is closed, water flows to the flushing check valve 208 through the check valve 205 in the combined valve body;

if the core electromagnetic valve 202 and the flushing electromagnetic valve 207 are both opened, water flows into the core pressure reducing valve 203 through the core electromagnetic valve 202, and the water is subjected to pressure stabilization through the core pressure reducing valve 203 and then flows into the ceramic water diversion valve 206 through the combination valve body internal check valve 205 and the core check valve 204 in sequence; meanwhile, water flows to the flushing check valve 208 after passing through the check valve 205 in the combined valve body.

In this embodiment, when only the core solenoid valve 202 is opened (i.e. when the core solenoid valve 202 is opened and the flush solenoid valve 207 is closed), water first flows into the core pressure reducing valve 203 through the core solenoid valve 202, then the water is stabilized in the core pressure reducing valve 203, then flows into the core check valve 204 through the check valve 205 in the combined valve body, and the water flows to the ceramic shunt valve 206 after being shunted by the core check valve 204, and finally flows to the next component (specifically, a foam box in the intelligent toilet) connected with the ceramic shunt valve 206.

When only the flush solenoid 207 is open (i.e. the flush solenoid 207 is open and the movement solenoid 202 is closed), water flows through the second conduit 2012 of the combination valve to the one-way valve 205 inside the combination valve body, then flows through the third conduit 2013 of the combination valve to the flush one-way valve 208, and finally flows to the next component (specifically, a water tank in an intelligent toilet) connected to the flush one-way valve 208.

When the movement solenoid valve 202 and the flushing solenoid valve 207 are both opened, the flow direction of the waterway is combined with the two situations, namely, the two shunted waterways are both communicated. Through the structure of the combined valve, the corresponding electromagnetic valve is opened selectively according to the water requirements of other functional components (such as a foam box and a water tank) in the intelligent toilet bowl.

In one embodiment, as a second embodiment of the combination valve, as shown in fig. 4 to 8, the combination valve 20 includes:

the combined valve body 201, and a movement electromagnetic valve 202 and a combined valve body inner one-way valve 205 which are arranged on the combined valve body 201;

the combination valve body 201 comprises a first end 201a and a second end 201 b; the combination valve body inner check valve 205 comprises a combination valve body inner check valve first valve 2053A;

wherein, the core electromagnetic valve 202 is arranged at the second end 201b of the combined valve body 201;

In the present embodiment, the difference from the first embodiment of the combination valve is that the structure of the combination valve 20 is simplified, and there is no need to provide a second combination valve sub-chamber and its corresponding structure (corresponding to the simplified water path structure where the flush solenoid valve 207 in the upper half of the first embodiment of the combination valve is located) as in the first embodiment of the combination valve. Water can be directly fed into the foam box body 410 through a waterway structure where the core electromagnetic valve 202 is located.

In one embodiment, as shown in fig. 4, 7a, 7b and 8, as a preferred embodiment of the combination valve body internal check valve, the combination valve body internal check valve 205 is of a vacuum explosion structure; the vacuum blasting structure includes:

a vacuum rupture disk 2051;

a vacuum rupture disk valve 2053 having one end flexibly connected to the vacuum rupture disk 2051;

and an air inlet arranged on the combined valve body 201 and matched with the vacuum blasting diaphragm valve 2053; the number of the air inlets is more than or equal to 2;

if the vacuum blasting diaphragm valve 2053 is subjected to positive pressure, the vacuum blasting diaphragm valve 2053 closes the air inlet; if the vacuum burst disk valve 2053 is under the negative pressure, the vacuum burst disk valve 2053 is separated from the air inlet.

In a specific application scenario, as shown in fig. 6, 7a, 7B, and 8, 2 air inlets are provided on the vacuum blasting diaphragm 2051, and are respectively marked as a first vacuum blasting diaphragm air inlet 2052A and a second vacuum blasting diaphragm air inlet 2052B, the number of the vacuum blasting diaphragm valves 2053 is 2, and is respectively marked as a first combined valve body check valve 2053A and a second combined valve body check valve 2053B, the first combined valve body check valve 2053A is connected with the vacuum blasting diaphragm 2051 through a first deformed thin wall 2054A, and the second combined valve body check valve 2053B is connected with the vacuum blasting diaphragm 2051 through a second deformed thin wall 2054B.

In specific implementation, the first one-way valve 2053A in the combination valve body is aligned with the fifth combination valve conduit 2015, and the second one-way valve 2053B in the combination valve body is aligned with the second combination valve conduit 2012.

In this embodiment, when negative pressure is generated in the fifth pipeline 2015 of the combination valve, the first thin deformation wall 2054A between the first valve 2053A of the one-way valve in the combination valve body and the vacuum rupture diaphragm 2051 bends and deforms 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 rupture diaphragm, so that the first air inlet 2052A of the vacuum rupture diaphragm is in an open state, and air enters from the first air inlet 2052A of the vacuum rupture diaphragm to achieve a blasting effect.

Similarly, when negative pressure is generated in the second pipeline 2012 of the combination valve, the second thin deformation wall 2054B between the second check valve 2053B and the vacuum rupture diaphragm 2051 in the combination valve body bends and deforms due to the negative pressure, and the second check valve 2053B is separated from the second air inlet 2052B of the vacuum rupture diaphragm in the combination valve body, so that the second air inlet 2052B of the vacuum rupture diaphragm is in an open state, and air enters from the second air inlet 2052B of the vacuum rupture diaphragm, thereby achieving the blasting effect.

In specific implementation, as shown in fig. 4, 7a, 7B and 8, the first combined valve body check valve 2053A and the second combined valve body check valve 2053B are both disposed on the side of the vacuum burst membrane 2051 close to the second end 201B, so that the first combined valve body check valve 2053A and the second combined valve body check valve 2053B are prevented from being flushed away by water during flowing, which may cause water leakage.

In this embodiment, the water in the flush check valve 208 can only flow in the direction of the arrow (as shown by the arrow in fig. 10), which is essentially a check valve to prevent the water from flowing in the reverse direction. Compared with the structure of the core one-way valve 204, the structure of the flushing one-way valve 208 is the same as that of the core one-way valve connector 2084 and the core one-way valve cover 2044, and has the same structure and the same principle of preventing water backflow.

That is, if water flows back into the flush check valve cavity 2081 from the flush check valve connection pipe 2084 (in the opposite direction of the arrow in fig. 10), the back-flowing water presses the flush check valve sealing ring 2083 against the sidewall of the flush check valve cavity 2081, so as to prevent water from flowing back into the combination valve body 201 and contaminating the combination valve body 201 and the valves therein.
