As shown in fig. 1-4, the steam device provided by the embodiment of the present invention includes:

a steam box 400;

a plurality of ports disposed on the steam box body 400, wherein the plurality of ports includes at least one steam box water outlet 401a and a steam box water inlet 402 b;

a water level detection assembly 4002 disposed in the steam box body 400;

a steam box water pump 403 connected with the steam box water outlet 401 a;

a steam generator 404 connected to the steam box water pump 403;

a combination valve 20 connected to the steam cartridge 400;

a steam outlet (not identified in the figure) connected to the steam generator 404.

In this embodiment, when the combination valve 20 is connected to a tap water network or other water source, water flows from the combination valve into the steam box inlet 402b, wherein the combination valve 20 is connected to the steam box inlet 402b via a steam box inlet line. The water in the steam box body 400 is pumped into the steam generator 404 (the steam generator 404 may be an instant boiler in specific implementation) by the steam box water pump 403 to be heated to generate high-temperature steam, and finally the high-temperature steam is output from a steam outlet (the steam outlet is connected with a steam spray gun in specific implementation).

Wherein, the steam generator 404 is directly connected with the steam outlet through a pipeline, or connected with the steam outlet through a connecting device, and is not particularly limited; the steam application means (e.g., a steam spray gun or a cleaning spray gun) connected after the steam outlet is also not particularly limited.

When the steam box body 400 is implemented, the steam box body 400 can be formed by clamping or welding (such as ultrasonic welding) the box body and the box cover, or the steam box body 400 with a steam box cavity inside can be formed by integral molding.

In one embodiment, as shown in fig. 1, 2b, and 2c, further comprises a breathing port disposed on the vapor cartridge 400; the breathing port is a through hole of the steam box body or a breathing port 4001 of the steam box body.

In one particular application scenario, as shown in fig. 2b, 2c, the vapor cartridge breathing port 4001 comprises:

a through hole 4001a, the through hole is disposed on the steam box 400, and a bottom surface of a second end surface (referring to a top cover part of the steam box 400 in fig. 1) of the steam box 400 is a breathing hole sealing wall 4001 b;

the floater accommodating chamber 4001c is arranged on the second end face of the steam box body, and the floater accommodating chamber 4001c is provided with a through hole and communicated with the through hole 4001a to form an air guide channel;

and a breathing port float 4001d, wherein the breathing port float 4001d is accommodated in the float accommodating chamber 4001c, and can cling to the breathing port sealing wall 4001b under the action of buoyancy to close the through port 4001 a.

The through hole 4001a is an opening penetrating the second end surface of the steam box 400. The through-openings may in particular take any suitable shape, configuration and size. The existing air vents arranged at the top of the water tank can be used.

In this embodiment, the bottom surface of the through hole 4001a at the second end surface of the steam box 400 (the surface facing the inside of the steam box 400) is a breathing hole sealing wall 4001 b. That is, when the breathing port float 4001d abuts against the breathing port sealing wall 4001b, the through hole 4001a will be closed. When the breathing port float 4001d is separated from the breathing port sealing wall 4001b, the through hole 4001a is kept open.

The float accommodating chamber 4001c is a chamber provided on the bottom surface of the tank cover for accommodating the breathing port float 4001 d. The float accommodating chamber 4001c has a set length, and the breathing port float 4001d can move up and down inside thereof with a change in water level.

The floater accommodating chamber 4001c is provided with a plurality of through holes communicated with the through holes to form an air guide channel.

During actual use, when the water level in the vapor cartridge 400 is in a normal state, the breathing float 4001d will remain at the bottom of the float receiving chamber 4001c or within the float receiving chamber 4001c without contacting the breathing port sealing wall 4001 b.

At this time, the air guide passage is not closed, and the external air can enter into the steam box body 400 through the through-hole of the through-hole 4001a and the float accommodating chamber 4001 c.

When the water level in the steam box 400 reaches the position of the breathing port float 4001d and tends to rise continuously, the breathing port float 4001d rises along with the water level until it abuts against the breathing port sealing wall 4001 b.

At this time, the breathing port float 4001d will close the through hole 4001a, blocking the air conduction channel, thereby preventing the water in the steam box 400 from overflowing through the through hole 4001 a.

In this embodiment, the steam generator 404 is connected to the steam outlet through a steam connection device, and the next flow direction of the liquid or gas flowing out of the steam generator 404 can be effectively controlled through the steam connection device. And if high-temperature steam flows from the steam outlet to the steam spray gun 407, the steam spray gun 407 can be used to aim at an object to be cleaned, so that the user can conveniently operate the steam spray gun 407 to clean the object.

In an embodiment, as another embodiment of the connection between the steam generator 404 and the steam outlet, the steam generator 404 and the steam outlet are connected by a steam connection device; wherein the steam connecting device comprises a reversing valve connected with a generator outlet of the steam generator (the reversing valve is not shown in fig. 3a and 3 b), a steam socket 405 connected with one of a plurality of reversing valve outlets of the reversing valve, and a steam plug 406 detachably connected with the steam socket 405;

and the other reversing valve outlet of the plurality of reversing valve outlets of the reversing valve is also connected with the cleaning spray gun inlet through a cleaning spray gun one-way valve.

In this embodiment, the flow of the fluid (e.g., hot steam or hot water) from the steam generator 404 to the diverter valve may be followed by the selected open diverter valve outlet to determine the next destination for the fluid. If the outlet of the reversing valve connected to the steam socket is opened, the fluid flowing out of the steam generator 404 passes through the steam socket 405, the steam plug 406, and finally reaches the steam outlet, which may be connected to a steam spray gun 407 and/or a cleaning spray gun (not shown in the figure). For example, when only the steam spray gun 407 is connected to the steam outlet, the outlet of the reversing valve connected to the inlet of the cleaning spray gun is controlled to be opened (at this time, the outlet of the reversing valve connected to the steam socket is closed), and then the fluid flowing out of the steam generator 404 sequentially passes through the one-way valve of the cleaning spray gun, the inlet of the cleaning spray gun, and finally reaches the cleaning spray gun. When the cleaning spray gun is implemented, the cleaning spray gun can be arranged on a main machine shell (the main machine shell can be understood as an intelligent toilet cover) arranged on a ceramic body of the intelligent toilet, and the cleaning spray gun can be aimed at the hip of a user for cleaning.

In an embodiment, as shown in fig. 1-4, the steam box 400 is provided with a plurality of ports, which are respectively a box top descaling liquid inlet 402d, a steam box water outlet 401a, a box descaling liquid inlet 401b, and a box descaling liquid outlet 401 c.

In a specific application scenario, the steam box 400 further includes a three-way structure connected to the steam box 400; the three-way structure comprises a steam box adapter port 402a, a steam box boiler water inlet 402c and a water pump interface water inlet 401d, wherein the water pump interface water inlet 401d, the steam box boiler water inlet 402c and the steam box adapter port 402a are sequentially communicated from bottom to top;

or the steam box comprises a steam box adapter port 402a, a steam box boiler water inlet 402c and a water pump interface water inlet 401d which are arranged on the steam box body; the water pump interface water inlet 401d, the steam box boiler water inlet 402c and the steam box adapter interface 402a are sequentially communicated from bottom to top.

In this embodiment, the three-way structure composed of the steam box adapter 402a, the steam box boiler water inlet 402c and the water pump interface water inlet 401d can be arranged on the steam box body 400 in an integrated manner, or can be separated from the steam box body in a split manner to form an independent three-way structure (the three-way structure is connected with the steam box body 400).

For example, when the three-way structure composed of the steam box adapter 402a, the steam box boiler water inlet 402c, and the water pump interface water inlet 401d is integrally disposed on the steam box 400, the steam box adapter 402a is communicated with the steam box boiler water inlet 402c and the water pump interface water inlet 401d, and the water flows only in the direction indicated by the arrow (see fig. 4).

Since the box top descaling liquid inlet 402d communicates with the box body descaling liquid outlet 401c, the descaling liquid flows into the steam box body 400 after flowing through the box top descaling liquid inlet 402 d. The descaling fluid in the vapor cartridge 400 can flow out of the cartridge descaling fluid outlet 401c and be pumped to the next location, e.g., the descaling fluid can flow out of the cartridge descaling fluid outlet 401c and be pumped to the cartridge descaling fluid inlet 401 b.

The steam box body 400 is provided with a steam box water outlet 401a, water entering the steam box body 400 from the steam box water inlet 402b is pumped to a water pump interface water inlet 401d by a steam box water pump 403, then flows to a steam box switching interface 402a from the water pump interface water inlet 401d, and then flows into the steam generator 404 through a steam generator pipeline to be heated to obtain high-temperature steam.

Through on the box top of steam box body with set up each interface of above-mentioned listing on the steam box body 400, can effectively insert descaling liquid and water, then through the flow direction of the tube coupling control water between the interface and descaling liquid to realize the drainage effect.

In one embodiment, as shown in fig. 2a, the apparatus further comprises a descaling fluid delivery pump 408 disposed on the steam box 400, and a descaling fluid box (not shown in fig. 1 and 2 a) connected to the inlet end of the adapting pipe 402e through a fourth connecting pipe of the steam box;

wherein, the delivery pump inlet 408b of the descaling liquid delivery pump 408 is connected with the descaling liquid outlet 401c of the box body through a fifth connecting pipe of the steam box;

and a conveying pump outlet 408a of the descaling liquid conveying pump 408 is connected with the descaling liquid inlet 401b of the box body through a sixth steam box connecting pipe.

Box body descaling liquid import 401b communicates with each other with box body descaling liquid export 401c, box body descaling liquid export 401c through steam box fifth connecting pipe with descaling liquid transfer pump 408's transfer pump entry 408b is connected, descaling liquid transfer pump 408's transfer pump exit 408a through steam box sixth connecting pipe with box body descaling liquid import 401b is connected. The steam box water pump inlet 403a is connected with the steam box water outlet 401a through a steam box third connecting pipe, and the steam box water pump outlet 403b of the steam box water pump 403 is connected with the water pump interface water inlet 401d through a steam box second connecting pipe.

As shown in fig. 1, fig. 3a and fig. 3b, a water inlet of the steam generator 404 is connected to the steam box adapter 402a through a steam generator pipe, a water outlet of the steam generator 404 is connected to one end of a steam connection device composed of a steam socket 405 and a steam plug 406 (specifically, one end of the steam socket 405 in the steam connection device is connected to the water outlet of the steam generator 404), and the other end of the steam connection device is connected to the steam spray gun 407 through a spray gun water pipe 407a (specifically, one end of the steam plug 406 away from the steam socket 405 in the steam connection device is connected to one end of the spray gun water pipe 407 a).

In this embodiment, as shown in fig. 4 and 5, the steam device has two operation modes, the first of which is a steam cleaning function mode, when it is detected that the steam plug 406 is plugged into the steam socket 405, the inlet water in the combination valve 20 flows into the steam box inlet 402b through the ceramic shunt valve in the combination valve 20 and then flows into the steam box body 400, and the steam box water pump 403 is operated to pump water from the steam box cavity of the steam box body 400 to the steam box outlet 401a, and the water flows to the water pump interface inlet 401d through the steam box water pump 403. Because the water pump interface water inlet 401d, the steam box boiler water inlet 402c and the steam box adapter 402a are sequentially communicated from bottom to top, at this time, water flows from the water pump interface water inlet 401d to the steam box adapter 402a, then flows into the steam generator 404 through a steam generator pipeline (for example, the steam generator 404 adopts an instant heating boiler in specific implementation) to be heated to generate high-temperature steam, the high-temperature steam sequentially passes through the steam connecting device and the spray gun water pipe 407a and then reaches the steam spray gun 407, and is sprayed out by the steam spray gun 407 to clean the ceramic body.

The second is a steam generator cleaning function mode, at this time, the steam socket 405 and the steam plug 406 are in a separated state, as shown in fig. 1 and fig. 3, the descaling fluid delivery pump 408 works, and the descaling fluid flows through the adaptor pipe 402e, the box top descaling fluid inlet 402d, and the box body descaling fluid inlet 401b from the descaling fluid box in sequence along the fourth connecting pipe of the steam box and then enters the steam box cavity of the steam box body 400. Meanwhile, one of the outlets of the ceramic shunt valves of the combination valve 20 into which water has entered is opened, and water flows out from the outlet of the ceramic shunt valve to the steam box water inlet 402b, and flows into the steam box cavity of the steam box body 400, and the water is mixed with the descaling fluid. When the mixed liquid of water and descaling liquid reaches a certain volume (for example, 0.5L), the steam box water pump 403 pumps the mixed liquid out of the steam box water outlet 401a, and the mixed liquid flows to the water pump interface water inlet 401d through the steam box water pump inlet 403a and the steam box water pump outlet 403b of the steam box water pump 403 in sequence. The mixed liquor then flows out of the steam box adapter 402a, which is in communication with the water pump interface water inlet 401d, and flows into the steam generator 404 through the steam generator tubing. When the volume of the mixed liquid in the steam generator 404 reaches a certain volume (e.g., 0.5L), the combination valve 20 stops feeding water, the water stops flowing into the steam box cavity, the steam box water pump 403 also stops working to stop pumping the mixed liquid from the steam box cavity into the steam generator 404, and the mixed liquid in the steam generator 404 is heated or kept still for a certain time (e.g., 5 min). The combined valve 20 is then re-flowed through the ceramic shunt valve into the steam box inlet 402b, then to the steam box boiler inlet 402c, and then through the steam box transition 402a to flow through the steam generator tubing into the steam generator 404. When water is continuously supplied into the steam generator 404, the mixed liquid after descaling, which is originally contained in the steam generator 404, flows into the ceramic body along the second outlet of the steam socket 405 by water pressure, wherein the second outlet of the steam socket 405 and the ceramic body are connected through the ceramic body connecting pipe. Through this mode of operation, can play the effect of clean scale in the steam generator.

That is, when the plug cavity 4061 of the steam plug 406 is inserted into the socket cavity 4051 of the steam socket, the hook at the bottom end of the plug button 4062 is clamped with the clamping structure 4057, the bottom end surface of the bottom end of the plug cavity 4061 (i.e., the first end 4061a of the plug cavity can be set to be a cylindrical surface during specific implementation) abuts against the socket reversing slider 4054 to move downward, at this time, the space between the socket reversing slider 4054 and the socket cavity 4051 is sealed by the socket reversing slider sealing ring 4055, and meanwhile, the space between the plug end cover 4063 and the plug cavity 4061 is sealed by the plug end cover sealing ring 4064. When steam of high temperature is generated in the steam generator 404, it enters the socket cavity 4051 from the socket inlet 4053 and then flows toward the steam nozzle 4065 in the direction of the steam flow arrow in fig. 9.

When the socket direction changing slider 4054 is in the initial position, the distance between the socket direction changing slider sealing ring 4055 and the bottom end of the socket cavity 4051 is greater than the distance between the socket inlet 4053 and the bottom end of the socket cavity 4051, so that the fluid flowing into the socket inlet 4053 does not flow into the socket cavity space above the socket direction changing slider 4054. However, when the socket direction changing slider 4054 moves downward and the distance between the socket direction changing slider sealing ring 4055 and the bottom end of the socket cavity 4051 is smaller than the distance between the socket inlet 4053 and the bottom end of the socket cavity 4051, the high temperature steam generated in the steam generator 404 can flow into the socket cavity space above the socket direction changing slider 4054 after entering the socket cavity 4051 from the socket inlet 4053, so that the flow guiding of the high temperature steam is realized when the steam plug 406 is inserted into the steam socket 405.

When the user inserts the steam plug 406 into the steam socket 405, the key hooks 4062b engage with the retaining structures 4057. If the user needs to detach the steam plug 406 from the steam socket 405, the user needs to press the button pressing point 4062a, the plug button body moves in a direction of approaching the central axis of the plug cavity 4061, at this time, the button hook 4062b is separated from the locking structure 4057, and the hook return spring 4062c is compressed by the pressure of the plug button body. When the user completely pulls out the entire steam plug 406 from the steam socket 405, the hook return spring 4062c recovers its deformation to move the plug button body from a direction close to the central axis of the plug cavity 4061 toward a direction away from the central axis of the plug cavity 4061, thereby achieving the return of the plug button body.

In this embodiment, the combination valve is applied to an intelligent toilet bowl, and is used for controlling the flow direction of water entering into the combination valve body 201. Specifically, the combination valve body 201 includes at least two combination valve cavities. For example, the combination valve body 201 includes a first combination valve sub-cavity and a second combination valve sub-cavity, a separation structure is arranged between the first combination valve sub-cavity and the second combination valve sub-cavity (the separation structure separates the first combination valve sub-cavity and the second combination valve sub-cavity, and then water paths cannot be communicated with each other), wherein an outlet end of the movement solenoid valve 202 is located in the first combination valve sub-cavity (that is, when the movement solenoid valve 202 is in an open state and an inlet end of the movement solenoid valve 202 is filled with water, water can flow into the first combination valve sub-cavity from the outlet end of the movement solenoid valve 202); the outlet of the flush solenoid 207 is located in the second combination valve sub-cavity (i.e. when the flush solenoid 207 is opened and the inlet of the flush solenoid 207 is filled with water, water can flow into the second combination valve sub-cavity from the outlet of the flush solenoid 207).

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.

The first outlet of the combined valve body and the second outlet of the combined valve body can be respectively connected with different devices so as to control the flow direction of water in the next step. For example, a ceramic shunt valve 206 is connected to a first outlet of the combined valve body, and a flushing check valve 208 is connected to a second outlet of the combined valve body.

As a preferred embodiment of the combination valve, as shown in fig. 11-15, the combination valve 20 includes a combination valve body 201, and a movement electromagnetic valve 202, a combination valve body internal check valve 205, and a flushing electromagnetic valve 207, which are arranged on the combination valve body 201;

the combined valve further comprises a movement pressure reducing valve 203 arranged on the combined valve body 201, and a pressure reducing valve 209 connected with the second end 201b of the combined valve body 201;

the valve also comprises a movement check valve 204 and a flushing check valve 208 which are arranged on the combined valve body 201;

the valve also comprises a ceramic shunt valve 206 arranged on 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 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 steam 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 steam box and a water tank) in the intelligent toilet bowl.

In an embodiment, as a second embodiment of the combination valve, as shown in fig. 11 to 15, 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;

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.

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. 11, 14A, 14B, and 15, 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 to the vacuum blasting diaphragm 2051 through a first deformed thin wall 2054A, and the second combined valve body check valve 2053B is connected to 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 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. 11, 14a, 14B and 15, 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. 17), 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. 17), the back-flowing water presses the flush check valve sealing ring 2083 against the side wall of the flush check valve cavity 2081, so as to prevent the water from flowing back into the combination valve body 201 and contaminating the combination valve body 201 and the valves therein.
