[0068] The present invention will be further described below with reference to specific embodiments:

[0069] <Example 1>

[0070] like Figure 1 As shown, a split wall-mounted siphon toilet includes a water tank mechanism 1, a suspension mechanism 2, a support mechanism 3, and an excretion mechanism 4.

[0071] The toilet in this embodiment is mainly used in prefabricated bathrooms. Generally, there is an installation space between the prefabricated bathroom wall 200 and the building wall 100, and the main drain pipe is arranged in the installation space. In this embodiment, the water tank mechanism 1 and the hanging mechanism 2 are located outside the prefabricated bathroom and within the installation space; the support mechanism 3 and the excretion mechanism 4 are located inside the prefabricated bathroom, which can save the internal space of the prefabricated bathroom.

[0072] Specifically, such as Figure 2 As shown, the suspension mechanism 2 includes a suspension upright 21 and a seat plate 22 made of metal, preferably steel plate. The seat plate 22 is a flat plate that is fixed to the floor of the building or under the basin of the prefabricated bathroom. The left and right sides of the suspension upright 21 are integrally formed with trapezoidal or triangular side plates. The seat plate 22 and the suspension upright 21 are vertically arranged and fixedly connected by welding or fasteners to provide stable support. In addition, the suspension mechanism 2 is a floor-mounted suspension mechanism, which eliminates the dependence of traditional wall-mounted brackets on wall anchoring, improving the independence and flexibility of toilet placement and installation.

[0073] Preferably, the hanging vertical plate 21 is provided with at least one avoiding part 211, and the avoiding part 211 of the embodiment is a hollow hole. A plurality of first fixing holes 212 for fixing the support mechanism 3 and a plurality of second fixing holes 213 for fixing the excretion mechanism 4 are arranged on the left and right sides of the avoiding part 211 respectively.

[0074] As shown in Figure 1 and 3 The support mechanism 3 comprises a seat body 31 mounted on the front side of the hanging vertical plate 21 and a gasket 32 rotatably arranged on the seat body 31.

[0075] The seat body 31 is provided with an empty part 311 in the middle and is fixed on the front side of the hanging vertical plate 21 by a first fastening assembly, which is used for users to sit and defecate, and is beneficial to provide stable support force.

[0076] Specifically, the first fastening assembly is a first fastening bolt, a first fastening nut and a first fastening washer. The seat body 31 is made of plastic, and a metal plate with a first mounting hole is embedded in the back of the seat body 31, preferably a steel plate. The corresponding first fastening bolt passes through the corresponding first fixing hole 212 and the first mounting hole and is fixedly connected with the corresponding first fastening washer and the first fastening nut.

[0077] In the embodiment, the seat body 31 is fixed and the gasket 32 is rotatable. When a man urinates, the gasket 32 needs to be turned up. When a man defecates or a woman defecates, the gasket 32 can be used by being turned down.

[0078] The excretion mechanism 4 comprises a water bucket 41 mounted on the front side of the hanging vertical plate 21 and located below the seat body 31. The water bucket 41 is fixed on the front side of the hanging vertical plate 21 by a second fastening assembly. The water bucket 41 is formed with an excretion cavity 411 corresponding to the empty part 311. The upper end of the water bucket 41 is provided with a flushing channel 42, and the lower end of the water bucket 41 is provided with an excretion channel 43 communicating with the excretion cavity 411 and a siphon channel 44 communicating with the main drainage pipeline.

[0079] Specifically, the second fastening assembly is a second fastening bolt, a second fastening nut and a second fastening washer. The water bucket 41 is made of ceramic, which has the advantages of small volume and simple modification. The back of the water bucket 41 is provided with a second mounting hole. The corresponding second fastening bolt passes through the corresponding second fixing hole 213 and the second mounting hole and is fixedly connected with the corresponding second fastening washer and the second fastening nut.

[0080] In addition, the water bucket can also be manufactured by SMC molding, plastic injection molding, or even transparent plastic, so that the dirt has no place to hide, and the artistic and sanitary level of the toilet bowl is also improved.

[0081] The siphon passage 44 of the embodiment is a separate component made of PVC plastic, has the characteristics of low cost, not easy to block, easy to install, water saving, quiet, etc., can also reduce the size of the discharge passage and the installation space. In addition, the pipeline of the siphon passage 44 is made of full-plastic molding process, which easily realizes smooth inner wall and equal cross section of the pipeline, and reduces the risk of pipeline blockage.

[0082] The seat body 31 and the water bucket 41 of the embodiment are separately arranged on the hanging vertical plate 21. The seat body 31 is used to bear the weight of the user, and the water bucket 41 does not need to bear the weight of the user, which effectively improves the stability and service life of the water bucket 41, and can reduce the risk of leakage of the discharge passage 43. In addition, the seat body 31 does not need to additionally bear the weight of the water bucket 41, which can reduce the installation difficulty of the seat body 31.

[0083] In addition, the gasket 32 can also be rotatably provided with a cover plate for sealing the discharge cavity 411.

[0084] Preferably, the empty part 311 extends downward on the side with a blocking part 312, which is an annular convex edge with an outer diameter substantially matching the inner diameter of the discharge cavity 411. The blocking part 312 extends into the upper end of the discharge cavity 411 but does not directly contact the water bucket 41, preventing the splashing of fecal liquid from the gap between the seat body 31 and the water bucket 41 during defecation, and ensuring the hygiene of the whole toilet.

[0085] Preferably, the seat body 31 and the water bucket 41 can be made of one or more of ceramic material, metal material and plastic.

[0086] As shown in Figure 1 and 4 The water tank mechanism 1 is arranged at the rear of the hanging vertical plate 21 and has a flushing interface 1121 and a siphon interface 1521, which respectively provide flushing water and siphon starting water for the flushing passage 42 and the siphon passage 44 of the water bucket 41.

[0087] Specifically, the flushing passage 42 communicates with the flushing interface 1121 of the water tank mechanism 1 after passing through the avoiding part 211.

[0088] The discharge passage 43 is connected with the siphon passage 44 after passing through the avoiding part 211. The bottom of the liquid inlet end of the siphon passage 44 is provided with a jet port 441, which communicates with the siphon interface 1521 of the water tank mechanism 1, and can reduce the fouling of the water bucket. At the same time, the jet port of the embodiment is arranged on the siphon passage, away from the discharge cavity, which improves the hygiene level of the discharge cavity.

[0089] The siphon channel 44 and the water bucket 41 form a water seal surface 300, and the water tank provides water for siphon starting and water sealing through the siphon interface 1521.

[0090] As shown in the drawings, the water tank mechanism 1 comprises a tank body 11, a water inlet unit 12, a water outlet control unit 13, and a jet control unit 15. Figure 11

[0091] The tank body 11 has a water storage part 111 for storing water, a water outlet part 112 for connecting to the toilet, and a water outlet control part 113 arranged between the water storage part 111 and the water outlet part 112.

[0092] The water storage part 111 has at least one water storage pipe 1111 with a diameter D1 ranging from 40 to 200 mm. The water storage pipe 1111 can be a plastic pipe or a metal pipe, and the preferred embodiment is a PVC plastic pipe with a diameter of 50 mm, 63 mm, 75 mm, 90 mm, 110 mm, 125 mm, 140 mm, 160 mm, etc. These diameter specifications are common PVC plastic pipe specifications on the market, which are easy to produce and purchase, low in cost, and convenient to assemble.

[0093] The water storage part 111 of the embodiment is in the shape of a pipe column, and compared with the traditional water tank, the cross-sectional area of the water storage part 111 is smaller, which reduces the installation area in the horizontal direction and improves the space utilization in the horizontal direction. At the same time, under the condition of the same volume and installation position, the height H1 of the water storage part 111 is higher, and the potential energy of the water is greater, which can provide greater water pressure and water outlet speed and improve the cleaning effect of the toilet.

[0094] As we all know, under the condition of a certain water tank volume (water storage capacity), the potential energy of water is proportional to the height of the water tank, and the height of the water tank is inversely proportional to the cross-sectional area of the water tank. In the case of allowing the installation height, the preferred embodiment can use a smaller size PVC plastic pipe, and compared with the traditional water tank, the cross-sectional area of the PVC plastic pipe can be reduced by more than half. In this way, the potential energy of the water can be increased by more than one time, thereby providing greater water pressure and water outlet speed and improving the cleaning effect of the toilet.

[0095] The water outlet control part 113 and the water outlet part 112 are integrally formed, the water outlet control part 113 has an annular side wall with a large upper end and a small lower end, the upper end of the annular side wall is integrally formed with a connecting part combined with the water storage part 111, and is connected with the water storage part 111 by special glue, heat melting or screw thread. The lower end of the annular side wall is integrally formed with the water outlet part 112, and the water outlet part 112 has a flushing interface 1121 and a water outlet interface 1122 connected to the flushing channel. ​

[0096] Preferably, the flushing interface 1121 is arranged on the side wall of the water outlet 112, and the water outlet interface 1122 is arranged at the bottom end of the water outlet 112, and an arc-shaped guide portion 1123 for guiding water to the flushing interface 1121 is arranged on the inner portion of the water outlet 112.

[0097] Generally, the water consumption of the flushing channel is greater than that of the siphon channel, but the siphon channel needs to provide water for siphon in advance when discharging sewage, so the water outlet interface 1122 is arranged at the bottom, and when the water outlet control unit 13 is opened, the water outlet interface 1122 can supply water to the siphon channel at the first time.

[0098] The radial width of the arc-shaped guide portion 1123 is determined by the amount of water required to enter the water outlet interface 1122, and generally the radial width of the arc-shaped guide portion 1123 occupies at least half of the inner diameter of the water outlet 112, and the extension line is slightly higher than the lowest point of the flushing interface 1121, which is beneficial to the outflow of more water from the flushing interface 1121 under the condition of meeting the water outlet interface water outlet.

[0099] In other words, in the present embodiment, the water outlet control portion 113 and the water outlet portion 112 correspond to a three-way connector, which can be a plastic connector or a metal connector.

[0100] In addition, the box body 11 can be installed on the wall surface of a building or the like through a water pipe bracket, for realizing the installation and fixation of the pipe column water tank.

[0101] The water inlet unit 12 is installed in the water storage portion 111 and has a water inlet valve 122 for connecting a tap water pipe 121, the water inlet valve 122 is a relatively mature accessory, and is mainly purchased externally, when the liquid level in the box body 11 is lower than the specified requirement, the water inlet valve 122 is opened, and the tap water pipe 121 discharges liquid; when the liquid level in the box body 11 meets the specified requirement, the water inlet valve 122 is closed, and the tap water pipe 121 stops discharging liquid.

[0102] As shown in Figure 11 Generally, there are two situations of failure of the water inlet valve 122, one is that the tap water pipe 121 cannot be opened, which will cause no water for the next flushing, and the user can discover it by himself in the next use; the other is that the tap water pipe 121 cannot be closed, which will cause waste of water resources if not discovered in time.

[0103] In order to detect the above-mentioned situations of the water inlet valve 122, the upper end of the water storage portion 111 is provided with an overflow port 1114, the overflow port 1114 is communicated with a water leakage box 141 having a waste water port, and the water leakage box 141 is provided with a water leakage alarm unit 142, when the water inlet valve 122 cannot be closed, the excess water in the box body 11 will flow into the water leakage box 141 from the overflow port 1114.

[0104] The water leakage alarm unit 142 is a circuit mainly composed of a small battery, a prompt light or a buzzer and two conductive ends extending into the water leakage box 141, and has a low cost. When the water leakage box 141 has water, the two conductive ends are conductive, the circuit is powered on, the prompt light flashes or the buzzer sounds an alarm, thereby reminding the user of the water tank failure and preventing the water leakage accident from further expanding, and saving water resources.

[0105] As shown in Figure 12 13 The water outlet control unit 13 has a water outlet valve core 131 for sealing / conducting the water outlet control part 113 and a switch assembly 132 for driving the water outlet valve core 131 to work.

[0106] The water outlet valve core 131 has a spherical part 1311 for plugging the annular side wall and a righting part 1312 arranged on the spherical part 1311. The spherical part 1311 is hollow and has a notch at the bottom; the righting part 1312 has a plurality of righting plates arranged on the upper end of the spherical part 1311, the width of the righting plates is adapted to the inner wall of the water storage part 111 and is greater than the outer diameter of the spherical part 1311, so that a water flow gap is formed between the inner wall of the water storage part 111 and the spherical part 1311.

[0107] The righting part 1312 is used to guide the water outlet valve core 131 to move along the direction of the inner wall of the water storage part 111, and can prevent it from swinging up and down. When falling, the water outlet valve core 131 can accurately plug the annular side wall.

[0108] The switch assembly 132 includes a connecting piece installed on the upper end of the water outlet valve core 131, at least one guide wheel 1322 installed on the tank 11 or other buildings, a pulling piece 1323 for manual rotation or pulling of the user, and a pull rope 1321 connected between the connecting piece and the pulling piece 1323. The pull rope 1321 is also installed on the guide wheel 1322. By rotating or pulling the pulling piece 1323, the water outlet valve core 131 is moved upward, thereby achieving water release. When the water in the water storage part 111 is released, the water outlet valve core 131 will automatically plug the annular side wall due to gravity. At this time, the water inlet valve 122 is opened, the water storage part 111 stores water, and the buoyancy of the water outlet valve core 131 is insufficient to make the water outlet valve core 131 float up at this time. On the contrary, under the action of water pressure and its own gravity, it will be sealed more tightly.

[0109] In order to limit the moving height of the water outlet valve core 131, a water outlet valve core limiting part 1112 for limiting the height direction movement of the water outlet valve core 131 is arranged inside the water storage part 111, and the water outlet valve core limiting part 1112 is an annular baffle structure.​

[0110] like Figure 11 As shown, the jet control unit 15 is used to control the amount of water entering the siphon channel 44, and it includes a housing and a control valve core 154.

[0111] The housing has a jet inlet section 151 that connects to the water outlet 1122, a jet outlet section 152 that connects to the siphon channel 44, and a jet control section 153 disposed between the jet inlet section 151 and the jet outlet section 152.

[0112] In this embodiment, the jet inlet section 151, the jet outlet section 152, and the jet control section 153 are all integrally formed. The upper end of the jet inlet section 151 is provided with a connecting section for connecting to the water outlet section 112, and is connected to the water outlet interface 1122 of the water outlet section 112 via special adhesive, heat fusion, or threaded connection. Alternatively, the jet inlet section 151 and the water outlet interface 1122 can be directly connected via a pipe fitting.

[0113] The jet control section 153 has an annular wall that is larger at the top and smaller at the bottom. The bottom of the annular wall is connected to the jet outlet section 152. The jet outlet section 152 has a siphon interface 1521 that is connected to the jet port of the siphon channel 44.

[0114] To better support the water tank mechanism 1, the jet outlet section 152 also has a support mounting port 1522 for mounting support components.

[0115] In this embodiment, the siphon interface 1521 is disposed on the side wall of the jet outlet section 152, and the support mounting port 1522 is disposed at the bottom of the jet outlet section 152. An arc-shaped guide wall 155 is disposed between the side wall of the jet outlet section 152 and the siphon interface 1521. The arc-shaped guide wall 155 serves two purposes: firstly, to guide the flow and reduce water flow resistance, so that the water used for siphon start-up can reach the siphon channel as quickly as possible, and at the same time, to reduce noise; secondly, to seal the support mounting port 1522.

[0116] A support member is provided on the support member mounting port 1522. The length of the support member is set according to the distance from the shell to the support surface (generally the ground). It is used to support the water tank mechanism 1 and increase the installation stability of the water tank mechanism 1.

[0117] The control valve core 154 is used to control the liquid outflow of the jet flow control section 153. The control valve core 154 has a hollow control inner cavity 1541, and at least one upper through hole 1542 is arranged on the top of the control valve core 154 to communicate with the control inner cavity 1541, which is used for internal exhaust, and the size of the upper through hole 1542 affects the exhaust efficiency. The bottom of the control valve core 154 is used to block the jet flow control section 153, and at least one lower through hole 1543 is arranged to communicate the control inner cavity 1541 and the jet flow control section 153, which is used for liquid inflow of the control inner cavity 1541.

[0118] Specifically, the control valve core 154 includes an upper valve core with the upper through hole 1542 and a lower valve core with the lower through hole 1543. The upper end of the upper valve core is arc-shaped, which is used for flow guiding to make water flow out of the jet flow inflow section 151 more quickly. The control inner cavity 1541 is formed between the upper valve core and the lower valve core. The upper valve core and the lower valve core are fixed together by clamping or glue connection or threaded connection or hot melting connection or welding, and have a pill shape.

[0119] The bottom of the control valve core 154 is shaped into an arc-shaped sealing part 1545 which is adapted to the annular wall part, and is used to control the liquid outflow area of the jet flow control section 153. A liquid discharge channel 1546 is arranged between the annular wall part and the arc-shaped sealing part 1545. The liquid discharge channel 1546 is at least one liquid discharge hole arranged on the arc-shaped sealing part 1545 or a liquid discharge slot arranged on the jet flow control section 153. When the control valve core 154 is blocked on the arc-shaped sealing part 1545, water in the shell can continue to be discharged through the liquid discharge channel 1546, which prevents water from accumulating at the bottom of the shell and avoids the growth of bacteria for a long time without use.

[0120] When water flows into the jet flow inflow section 151 of the shell, the control valve core 154 needs to float up by the buoyancy of the control inner cavity 1541 to open the jet flow control section 153, thereby quickly providing water for siphon start. Therefore, the upper through hole 1542 and the lower through hole 1543 should not be too large, otherwise it will affect the floating speed of the control valve core 154. At the same time, when the water for siphon start is finished (after 1-2 seconds), the control valve core 154 needs to sink quickly to block the jet flow control section 153, thereby quickly reducing the liquid outflow of the jet flow control section 153 to prevent water waste. Therefore, the control valve core 154 must be made of a material with a density greater than water, or a counterweight is arranged to achieve this, so that when a certain amount of water enters the control inner cavity 1541, its gravity will be greater than the buoyancy, which can achieve rapid sinking.

[0121] As Figure 15As shown, the side wall of the control valve core 154 is circumferentially provided with a plurality of guide protrusions 1544 matched with the inner wall of the jet inlet section 151, which are used for guiding the control valve core 154 up and down and setting a flow gap between the control valve core 154 and the inner wall of the jet inlet section 151.

[0122] Preferably, the inner wall of the water outlet section 112 or the jet inlet section 151 is provided with a control valve core limiting portion 1512 for limiting the movement of the control valve core 154 in the height direction. In the embodiment, the valve core limiting portion 1512 is arranged on the inner wall of the water outlet section 112.

[0123] Specifically, the valve core limiting portion 1512 is an arc-shaped blocking edge, which is arranged on the side away from the arc-shaped guide portion 1123 and flush with the arc-shaped bottom of the flushing interface 1121, facilitating the production of the tee joint and providing drainage for the flushing interface 1121.

[0124] Principle of the water tank mechanism 1:

[0125] When the water outlet control unit 13 is opened, most of the water will enter the flushing channel through the flushing interface 1121 under the guidance of the arc-shaped guide portion 1123, and the other part of the water will enter the jet inlet section 151 through the water outlet interface 1122.

[0126] Since the control valve core 154 is hollow, when water flows in, it will instantly fill the entire jet inner cavity of the shell (the jet inner cavity is always filled with water before the water in the tank 11 is used up). Since the control valve core 154 is hollow, the buoyancy generated is greater than the gravity, so that the control valve core 154 floats up and controls the liquid outlet of the jet outlet section 152, thereby quickly providing water for siphon starting to the siphon channel 44. At the same time, the control inner cavity 1541 will be filled with water through the lower through hole 1543, and the air inside will be discharged from the upper through hole 1542 until the control inner cavity 1541 is filled with water.

[0127] With the air in the control inner cavity 1541 being discharged, the buoyancy of the control valve core 154 will decrease, and when its gravity is greater than the buoyancy, it will quickly move down and block the jet control section 153 again. At this time, the water supply for siphon starting is finished. Preferably, the time for the control valve core 154 to block the jet control section 153 again should be controlled after the siphon starting.

[0128] At this time, since the water in the jet flow cavity and the control cavity 1541 is also drained through the lower through hole 1543 of the control cavity 1541 and the drainage channel 1546, the water is slowly drained at a rate much lower than the rate of the siphon starting water, and the duration is greater than the flushing time. Therefore, after the water bucket 41 is flushed, this part will continue to be provided to the water bucket 41 through the siphon channel 44 and used as water seal water, thereby saving the siphon starting water that is otherwise partially wasted and improving the utilization rate of water resources. Compared with the traditional water tank, the same cleaning effect can be achieved with less water.

[0129] In addition, the siphon channel 44 and the water bucket 41 have a water seal surface, and the lowest position of the jet control section 153 of the embodiment is higher than the water seal surface 300 of the siphon channel 44, and the control valve core 15 is generally higher than or equal to the lowest position of the jet control section 153. Therefore, as long as there is water in the control cavity 1541 or the inside of the shell, it can flow out to the siphon channel 44 under the action of potential energy and form a water seal.

[0130] When the water level of the water bucket 41 is higher than the water seal surface, the water will automatically drain.
