Description

Technical Field

[0001] The present invention relates to the technical field of foam devices, and in particular to a foam device and an intelligent toilet seat thereof. Background Art

[0002] At present, smart toilets have been used more and more widely. In the initial stage of development, smart toilets were mainly used for medical and elderly care, and were originally equipped with warm water cleaning functions. Later, sanitary ware companies in South Korea and Japan gradually introduced technology and began to manufacture them, adding toilet seat heating, warm water cleaning, warm air drying, sterilization and other functions.

[0003] At present, the most common smart toilets are roughly divided into three types: one is a smart toilet with cleaning, heating, sterilization, etc., the second is a smart toilet with automatic cover change, and the third is a smart toilet with automatic cover change and cleaning function. When the above three types of toilets are used by users, a certain amount of water will be stored in the ceramic body for water sealing and odor isolation. This part of water is prone to splashing during use, and the odor isolation effect is poor. Summary of the invention

[0004] The embodiment of the present invention proposes a foam device and a smart toilet thereof, aiming to solve the problem that in the prior art, the smart toilet is not provided with a foam device for generating foam to assist in adding foam to the water in the ceramic body for sealing and isolating odor, which causes this part of the water to be easily splashed during use by the user and has a poor odor-isolating effect.

[0005] In a first aspect, an embodiment of the present invention provides a foam device, comprising:

[0006] Foam box body;

[0007] The foam box body is provided with a first installation position;

[0011] The foam box body is also provided with a foam box outlet;

[0012] The combination valve transports water into the foam box body, and at the same time, the foaming agent in the foaming agent box flows into the foam box body. At the same time, the foam box air pump transports gas into the foam box body. The water, gas and foaming agent in the foam box body produce foam through the combined action, and the foam is output from the foam box outlet arranged on the foam box body.

[0013] In a second aspect, an embodiment of the present invention provides an intelligent toilet, comprising the foam device described in the first aspect.

[0014] By applying the technical solution of the present embodiment, the combination valve can transport water into the foam box body of the foam box body, while the foaming agent in the foaming agent box flows into the foam box body, and the foam box air pump can transport gas into the foam box body. The water, gas and foaming agent in the foam box body produce foam through the combined action, and the foam is output through the foam box outlet provided on the foam box body. The foam output through the foam box outlet can enter the ceramic body to prevent water in the ceramic body from splashing during use by the user, and also has an odor-isolating effect.

[0040] The combination valve 20 transports water into the foam box body, and at the same time, the foaming agent in the foaming agent box 430 flows into the foam box body 410. At the same time, the foam box air pump 421 transports gas into the foam box body 410. The water, gas and foaming agent in the foam box body 410 produce foam through the combined action, and the foam is output from the foam box outlet provided on the foam box body 410.

[0041] In this embodiment, the foam box outlet is connected to the ceramic body, that is, foam is generated in the foam box body 410 by the combined action of water, gas and foaming agent, and the foam is output to the ceramic body through the foam box outlet arranged on the foam box body 410 to enhance the cleaning effect on the ceramic body.

[0042] In one embodiment, if Figure 2b As shown, a second installation position 4102 is also provided on the foam box body 410 ; a foaming agent delivery pump 440 is also provided on the second installation position 4102 .

[0043] In a specific application scenario, the combination valve 20 transports water into the foam box body 410, and at the same time, the foaming agent in the foaming agent box 430 is pumped into the foam box body 410 by the foaming agent delivery pump 440, and at the same time, the foam box air pump 421 transports gas into the foam box body 410, and foam is generated by the combined action of water, gas and foaming agent in the foam box body 410, and the foam is output from the foam box outlet set on the foam box body 410.

[0044] In this embodiment, the foaming agent delivery pump 440 is used to pump the foaming agent in the foaming agent box into the foam box body 410, the combination valve 20 is used to deliver water into the foam box body 410, and the foam box air pump 421 is used to deliver gas into the foam box body 410. Foam is generated by the combined action of water, gas and foaming agent in the foam box body 410.

[0045] In one embodiment, if Figure 3 As shown, it also includes a foaming component 422 disposed in the foam box body 410.

[0046] In a specific application scenario, the foaming component 422 is a foaming stone, a porous filter, or an air hole provided on the foam box body 410 .

[0047] In this embodiment, the inlet end of the foaming component 422 is connected to the foam box air pump 421, and the outlet end of the foaming component 422 is located on the foam box body 410. The foaming component 422 is used to convert the input gas into a plurality of small bubbles.

[0048] In one embodiment, if Figure 1 , Figure 2a , Figure 2b and Figure 3 As shown, the foam box body 410 is also provided with a plurality of interfaces, namely, a foaming agent inlet 412a at the top of the box, a foam box water inlet 412b, and a foam box outlet 412c, a box body foaming agent inlet 411a, a box body foaming agent outlet 411b, an air pump interface inlet 411c, and an air pump interface outlet 411d.

[0049] In a specific application scenario, the foaming agent inlet 412a at the top of the box is connected to the foaming agent box 430; the combination valve 20 is connected to the foam box water inlet 412b through the foam box water inlet pipeline;

[0050] The box body foaming agent outlet 411b is communicated with the box top foaming agent inlet 412a; the box body foaming agent inlet 411a is communicated with the foam box cavity in the foam box; the air pump interface inlet 411c is connected to the foam box air pump 421 through the foam box gas inlet pipeline; the air pump interface outlet 411d is communicated with the air pump interface inlet 411c.

[0051] In particular, the foam box body 410 can be formed by snapping or welding (such as ultrasonic welding) the box body and the box cover, or it can be integrally formed to form a foam box body 410 including a foam box cavity.

[0052] In this embodiment, it is preferred to set the foaming agent inlet 412a at the top of the box, the foam box water inlet 412b, and the foam box outlet 412c at the top of the foam box body 410. The foam box water inlet 412b is set on the foam box body 410 to facilitate the delivery of water to the foam box cavity in the foam box body 410. The foaming agent inlet 412a at the top of the box is set on the foam box body 410 to deliver the foaming agent to the foam box cavity in the foam box body 410. The foam box outlet 412c is set on the foam box body 410 to facilitate the output of foam to the next device (such as a ceramic body) connected to the foam box outlet 412c through a connecting pipe.

[0053] The foam box body 410 is provided with a box body foaming agent inlet 411 a and a box body foaming agent outlet 411 b to facilitate the flow of the foaming agent, so that the foaming agent finally flows into the foam box cavity in the foam box body 410 .

[0054] The foam box body 410 is provided with an air pump interface inlet 411c and an air pump interface outlet 411d to facilitate the flow of gas, so that the gas eventually flows into the foam box cavity.

[0055] In one embodiment, if Figure 2a , Figure 2b and Figure 3 As shown, the air pump outlet 421a of the foam box air pump 421 is connected to the air pump interface inlet 411c;

[0056] The inlet end of the foaming component 422 is connected to the air pump interface outlet 411d through a foaming component air inlet pipe; the outlet end of the foaming component 422 is located in the foam box body (specifically, the outlet end of the foaming component 422 is located in the foam box cavity in the foam box body).

[0057] In the present embodiment, the foam box air pump 421 and the foaming component 422 can be combined to generate bubbles, and the air is pumped into the foaming component 422 by the foam box air pump 421, and the air is converted into a plurality of small bubbles by the foaming component 420 and enters the foam box cavity, and the bubbles are generated by the water and the foaming agent. Specifically, after the foam box air pump 421 pumps the external gas in the surrounding environment, the gas flows through the air pump outlet 421a, the air pump interface inlet 411c, the air pump interface outlet 411d, and the foaming component 422 in sequence, and finally flows into the foam box cavity. The gas blown out from the foaming component 422 acts together with the water and the foaming agent in the foam box cavity to generate bubbles, and then the bubbles can flow out from the foam box outlet 412c to the next device (such as a ceramic body) connected to the foam box outlet 412c through a connecting pipeline.

[0058] In one embodiment, if Figure 2b As shown, the delivery pump inlet 441 of the foaming agent delivery pump 440 is connected to the foaming agent outlet 411b of the box body, and the delivery pump outlet 442 of the foaming agent delivery pump 440 is connected to the foaming agent inlet 411a of the box body.

[0059] In this embodiment, in order to enhance the power of pumping the foaming agent from the foaming agent box 430 into the foam box cavity, a foaming agent delivery pump 440 can be provided on the foam box 411. When the foaming agent delivery pump 440 starts working, the foaming agent takes the foaming agent box 430 as the starting point of the flow path, passes through the foaming agent inlet 412a at the top of the box, the foaming agent outlet 411b of the box body, the foaming agent delivery pump 440, and the foaming agent inlet 411a of the box body in sequence, and the foaming agent finally flows into the foam box cavity of the foam box body 410.

[0060] In one embodiment, if Figure 1 As shown, a transfer tube 412d is also provided on the foam box body 412; wherein, the transfer tube inlet of the transfer tube 412d is connected to the outlet of the foaming agent box 430 through the foam box foaming agent inlet pipeline, and the transfer tube outlet of the transfer tube 412d is connected to the foaming agent inlet 412a at the top of the box.

[0061] In this embodiment, an adapter tube 412d is also provided on the foam box body 412 in order to set a unified adapter joint, which can be externally connected to other components (such as a foaming agent box, a descaling liquid box, etc.), and can also be installed on other devices.

[0062] In one embodiment, as a first embodiment of a combination valve, as Figure 4-Figure 8 As shown, the combination valve 20 includes:

[0063] 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;

[0064] 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;

[0065] 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;

[0066] 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 .

[0067] In a specific application scenario, at least one combination valve pressure reducing valve is also provided on the combination valve body 201 .

[0068] 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 separates 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).

[0069] 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).

[0070] 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.

[0071] As a preferred embodiment of the combination valve, Figure 4-Figure 8As shown, the combination valve 20 includes a combination valve body 201, a core solenoid valve 202, a combination valve body check valve 205, and a flushing solenoid valve 207 arranged on the combination valve body 201;

[0072] 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;

[0073] 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;

[0074] It also includes a core check valve 204 and a flush check valve 208 disposed on the combined valve body 201;

[0075] It also includes a ceramic water diverter valve 206 disposed on the combined valve body 201;

[0076] 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;

[0077] 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;

[0078] The movement pressure reducing valve 203 is located at a side of the movement solenoid valve 202 away from the second end 201b;

[0079] The core one-way valve 204 is located at a side of the core pressure reducing valve 203 away from the second end 201b;

[0080] The flushing check valve 208 is located at a side of the flushing solenoid valve 207 away from the second end 201b;

[0081] 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.

[0082] 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;

[0083] 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;

[0084] 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;

[0085] 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;

[0086] 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;

[0087] 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;

[0088] 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);

[0089] 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);

[0090] 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).

[0091] 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.

[0092] 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;

[0093] 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;

[0094] 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.

[0095] 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 foam box in the smart toilet).

[0096] 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).

[0097] 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, the corresponding solenoid valves are selectively opened according to the water demand of other functional components (such as the foam box and the water tank) in the intelligent toilet.

[0098] In one embodiment, as a second embodiment of the combination valve, as Figure 4-Figure 8 As shown, the combination valve 20 includes:

[0099] A combined valve body 201, a core solenoid valve 202 arranged on the combined valve body 201, and a one-way valve 205 in the combined valve body;

[0100] 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;

[0101] The core solenoid valve 202 is disposed at the second end 201b of the combined valve body 201;

[0102] The one-way valve 205 in the combined valve body is located at the first end 201a of the combined valve body 201 ; the first one-way valve 2053A in the combined valve body is arranged opposite to the core solenoid valve 202 .

[0103] In this 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 set the second combination valve sub-cavity and its corresponding structure as in the first embodiment of the combination valve (equivalent to simplifying the water path structure where the flushing solenoid valve 207 in the upper half of the first embodiment of the combination valve is located). Water can be directly introduced into the foam box 410 through the water path structure where the core solenoid valve 202 is located.

[0104] In one embodiment, if Figure 4 , Figure 7a , Figure 7b and Figure 8 As shown, as a preferred embodiment of the one-way valve 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:

[0105] Vacuum bursting diaphragm 2051;

[0106] A vacuum bursting diaphragm valve 2053 having one end flexibly connected to the vacuum bursting diaphragm 2051;

[0107] 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;

[0108] 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.

[0109] In a specific application scenario, such as Figure 6 , Figure 7a , Figure 7b and Figure 8As 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] When implementing it, Figure 4 , Figure 7a , Figure 7b and Figure 8 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.

[0114] In one embodiment, if Figure 4 , Figure 5a , Figure 9a and Figure 9b 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;

[0115] The movement one-way valve sealing ring 2043 is sleeved on one end of the movement one-way valve bracket 2042 .

[0116] In this embodiment, the water in the core check valve 204 can only be discharged according to the arrow (such as Figure 9b It is essentially a one-way valve to prevent water from flowing in the reverse direction.

[0117] 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.

[0118] 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 .

[0119] 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.

[0120] If water flows back from the one-way valve cover 2044 into the one-way valve cavity 2041 (such as Figure 9bThe 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.

[0121] In one embodiment, if Figure 4 , Figure 5a , Fig.10 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;

[0122] The flushing one-way valve sealing ring 2083 is sleeved on one end of the flushing one-way valve bracket 2082 close to the flushing solenoid valve 207;

[0123] 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 .

[0124] In this embodiment, the water in the flush check valve 208 can only be flushed according to the arrow (such as Fig.10 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.

[0125] That is, if water flows back from the flush check valve pipe 2084 into the flush check valve cavity 2081 (such as Fig.10 ), 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.

[0126] The embodiment of the present invention also provides an intelligent toilet, including the foam device. By arranging the foam device in the intelligent toilet, the combined valve delivers water to the foam box cavity of the foam box body, and the foaming agent box delivers the foaming agent to the foam box cavity, and the foam box bubble generating component delivers gas to the foam box cavity, and the water, gas, and foaming agent in the foam box cavity jointly generate foam, and the foam is outputted from the foam box outlet arranged on the foam box body, and the foam outputted through the foam box outlet can enter the ceramic body to prevent the water in the ceramic body from splashing during use by the user, and also has a odor isolation effect.
