DETAILED DESCRIPTION
[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.
[0032] The embodiment of the present application provides an anti-siphon device for installation in a toilet, such as Figure 1-Figure 6As shown, the anti-siphon device 1 comprises: a shell with a cavity formed inside, and a water inlet interface 111 and a water outlet interface 121 are provided on the shell;
[0033] The shell is also provided with an overflow port 122 and a vent, wherein the overflow port 122 is located at the bottom of the shell, and an overflow pipe 123 is provided in the shell surrounding the overflow port 122 and extending upward from the overflow port 122. When the water level in the shell is higher than the top opening of the overflow pipe 123, the water can enter the overflow pipe 123 and flow out of the overflow port 122. The vent is higher than the overflow pipe 123, and the inside of the shell can be ventilated with the outside through the vent.
[0034] The anti-siphon device provided in the embodiment of the present application can be used to connect to the upstream of the water tank of the toilet. By setting the vent to balance the pressure inside and outside the shell, it can prevent the water from flowing back to the water inlet component and polluting the water source when the upstream water inlet component has negative pressure. By setting the overflow port, when the water level is higher than the preset height due to the continuous water supply of the water inlet component, the water can flow out from the overflow port, so that the water flows away along the set overflow path.
[0035] In the technical solution provided in the embodiment of the present application, by setting the overflow port 122 at the bottom of the shell, water overflows from the overflow pipe 123 when it is higher than the preset water level, and then flows out from the overflow port 122 at the bottom. The overflow port is set at the bottom of the shell to facilitate the discharge of overflow water. For example, water can be discharged directly from the bottom of the shell, or the overflow port is located at the bottom to make it easier to connect the overflow port 122 through a pipeline, for example, to a sewage pipe of a toilet or to other structures that can drain water. In other words, setting the overflow port 122 at the bottom of the shell makes it easier to arrange the preset flow path of the overflow water.
[0036] In one embodiment, if Figure 1 As shown, the housing includes a first top housing 113 and a second top housing 114 located at the top, and the cavity includes a first cavity 14 located below the first top housing 113 and a second cavity 15 (reference Figure 5 ), the water inlet interface 111 is arranged corresponding to the first cavity 14 so that water flows to the first cavity 14, and the overflow pipe 123 is located in the second cavity 15; wherein, the vent includes a first vent 1131 located on the first top shell 113 and a second vent 1141 located on the second top shell 114, and the vents are respectively arranged on the first top shell 113 and the second top shell 114, so that both parts of the cavity can be effectively ventilated to achieve pressure balance inside and outside the shell.
[0037] In this embodiment, the cavity is divided into a first cavity 14 and a second cavity 15 which are connected. The water inlet interface 111 is arranged corresponding to the first cavity 14, and the overflow pipe 123 is located in the second cavity 15. Water first flows into the first cavity 14 from the entrance of the water inlet interface 111, and then flows into the second cavity 15. This can avoid splashing water to the overflow pipe 123, thereby avoiding the situation where water still flows out of the overflow port 122 in a non-overflowing state.
[0038] In one example, reference Figure 4 and Figure 5 The second vent 1141 is located directly above the overflow pipe 123 , and the second vent 1141 is connected to the overflow pipe 123 up and down, so the air flow is smooth, which is more conducive to the balance of air pressure inside and outside the shell.
[0039] In one example, if Figure 1 As shown, the second top shell 114 is lower than the first top shell 113. Setting the first top shell 113 higher can make the first cavity 14 have a higher height, which is conducive to arranging a structure such as a water diversion structure in the first cavity 14. For example, the second tube body 1122 and the water diversion component 13 for diverting water are arranged in the first cavity as described below, so that the water can flow down slowly, and the height of the second top shell 114 only needs to be located above the overflow pipe 123 to meet the water level height in the shell. Therefore, the height of the second top shell 114 can be set lower than the first top shell 113, which can save layout space.
[0040] In one example, if Figure 1 and Figure 6 As shown, the shell includes a shell body 12 and a cover body 11 located above the shell body 12 , and the cover body 11 and the shell body 12 are buckled together to form the cavity, wherein the cover body 11 has the first top shell 113 and the second top shell 114 .
[0041] like Figure 6 In the example shown, a buckle 115 is provided on the cover body 11 , and a clamping block 124 is provided on the shell body 12 . The cover body 11 is connected to the shell body 12 by clamping the buckle 115 and the clamping block 124 .
[0042] The housing is also provided with a connecting portion 16 for mounting the anti-siphon device. For example, the anti-siphon device can be connected to the base assembly 4 of the toilet through the connecting portion (refer to Figure 7 and Figure 8 ). Figure 6 In the example shown, the cover body 11 and the shell body 12 may be respectively provided with a first connecting portion 16 , and the shell body 12 is provided with a connecting portion 16 , which is installed and fixed by passing bolts through the connecting portion 16 .
[0043] In one embodiment, if Figure 1 and Figure 5 As shown, a water inlet pipe 112 with a water inlet interface 111 is provided on the shell, and the water inlet pipe 112 includes a first tube body 1121 extending into the cavity of the shell, and the first tube body 1121 is used to drain the water entering the cavity to prevent water splashing.
[0044] The water inlet pipe 112 further includes a second tube body 1122 located outside the cavity. The second tube body 1122 is bent toward one side relative to the first tube body 1121. The second tube body 1122 is arranged on one side so as to be conveniently used for connecting the water inlet assembly.
[0045] In one embodiment, the vent includes a first vent 1131, which is arranged along the circumference of the first tube 1121, and the angle along the circumference is greater than 180 degrees. The first vent 1131 is arranged along the circumference of the first tube 1121, so that the first vent 1131 has a larger area, which is conducive to sufficient ventilation.
[0046] In one embodiment, a water guiding component 13 for guiding water coming from the water inlet interface 111 may be further disposed in the cavity, and the water guiding component 13 includes a water baffle 131 disposed obliquely.
[0047] like Figure 5 and Figure 6 In the example shown, a bolt connection portion 133 is provided on the water guide component 13, and the water guide component 13 can be connected to the inner wall of the shell through the bolt connection portion 133. In order to ensure the stability of the water baffle 131, a support column 132 is also connected to the bottom of the water baffle 131, and the support column 132 can be supported on the bottom of the shell, so that when the water flow hits the water baffle 131, the water baffle 131 has stability.
[0048] like Figure 5 In the example shown, the water inlet pipe 11 at the water inlet interface 111 is provided with a first tube body 1121 extending into the cavity, and the water baffle 131 is correspondingly arranged below the first tube body 1121. The water outlet of the first tube body 1121 flows onto the water baffle 131, and then flows down along the water baffle 131. The water flows down slowly, which can effectively prevent water splashing.
[0049] In this example, the upper surface of the water baffle 131 is set away from the overflow pipe 123, and the water is diverted to a position away from the overflow pipe 123 and then falls to the bottom of the shell, which can prevent water from splashing into the overflow pipe 123, thereby preventing water from still flowing out of the overflow port 122 in a non-overflow state.
[0050] The embodiment of the present application also provides a toilet water system, such as Figure 7-Figure 9As shown, it includes a water inlet assembly 2, a water tank 5 and the anti-siphon device 1 as described above, wherein the water inlet assembly 2 is connected to the water inlet interface 111 of the anti-siphon device 1, and the water tank 5 is connected to the water outlet interface 121 of the anti-siphon device 1.
[0051] An embodiment of the present application further provides a toilet, comprising a toilet body and the toilet water system as described above installed on the toilet body.
[0052] In one embodiment, a base assembly 4 is provided on the toilet, and the anti-siphon device 1 can be installed on the base assembly 4. Figure 7 and Figure 8 As shown, the anti-siphon device 1 can be installed on the base assembly 4, and then the base assembly 4 is installed on the toilet body. A water inlet assembly 2 is also installed on the base assembly 4, and the water inlet assembly 2 has a water inlet 21 connected to a water source, and also has a water inlet pipe 22 connected to the water inlet interface 111 of the anti-siphon device 1. The water inlet assembly can also include a control component such as a solenoid valve for controlling water inlet.
[0053] refer to Fig. 9 After the base assembly 4 is installed on the toilet body, the water outlet interface 22 of the anti-siphon device 1 is connected to the water tank 5 through the water outlet pipe 3, and the water tank 5 supplies water to the spray head assembly of the toilet.
