DETAILED DESCRIPTION
[0033] 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.
[0034] The embodiment of the present application provides a water tank for installation in a toilet, such as Figure 1-Figure 7 As shown, the water tank 1 includes a box body 11 formed with a water storage chamber 118, and the box body 11 is provided with a water inlet 113 and a water outlet 114 connected to the water storage chamber 118; wherein, the box body 11 is also provided with an overflow port 116, when the water level in the water tank exceeds a predetermined height, the water in the water tank flows out from the overflow port 116.
[0035] The technical solution provided by the embodiment of the present application is to set an overflow port 116 on the box body 11. When a problem occurs in the water inlet component that supplies water to the water tank or other structural failures occur (for example, failure of the liquid level meter leads to inaccurate liquid level detection) and the water in the water tank 1 exceeds a predetermined height, the water in the water tank 1 can overflow from the overflow port 116, and the overflowing water can flow away along a set overflow path, for example, be guided to a sewage pipe through a pipeline for discharge or guided to flow into the pelvic cavity of the toilet, so that the overflow water will not flood the bathroom or cause damage to electronic components.
[0036] In the case where the overflow port 116 of the water tank 1 is connected to a sewage pipe of a toilet, the overflow water of the water tank 1 can be discharged from the sewage pipe, but the odor of the sewage pipe will flow into the water tank 1 from the overflow port 116 and be emitted from the water tank 1 to the atmosphere, thus affecting the environment. Figure 4 , Figure 5 and Figure 7The water tank 1 further comprises a water seal structure 15 disposed in the box body 11, wherein the water seal structure 15 forms a water seal cavity 157, and the water seal structure 15 is configured to separate the overflow port 116 from the water storage cavity 118 through the water in the water seal cavity 157; wherein the water in the water storage cavity 118 flows into the water seal cavity 157 when it exceeds a predetermined height, and the water in the water seal cavity 157 flows out to the overflow port 116. By providing the water seal structure 15, it is possible to prevent odor from entering the water tank 1 from the overflow port 116 and being emitted from the water tank 1 to the atmosphere.
[0037] In one exemplary embodiment, Figure 4 and Figure 5 As shown, the water seal structure 15 includes a first partition 151 and a second partition 152 , wherein the first partition 151 is located between the water storage chamber 118 and the water seal chamber 157 , and the second partition 152 is close to the overflow port 116 , wherein the height of the first partition 151 is greater than the height of the second partition 152 .
[0038] The height of the first partition 151 determines the water level of the predetermined height of the water storage chamber 118. When the water in the water storage chamber 118 reaches the top of the first partition 151 (that is, the water level in the water storage chamber 118 reaches the predetermined height), it will flow into the water seal chamber 157 from the top of the first partition 151. There is usually water for water sealing in the water seal chamber 157. After the water in the water storage chamber 118 enters the water seal chamber 157, the water level in the water seal chamber 157 exceeds the second partition 152, so that the water will flow out from the top of the second partition 152 to the overflow port 116.
[0039] In an exemplary embodiment, the overflow channel 17 is formed on the side of the second partition 152 away from the first partition 151, and the overflow port 116 is located at the lower end of the overflow channel 17. By arranging the overflow port 116 at the lower end, it is convenient to arrange the pipeline between the overflow port 116 and the sewage pipe of the toilet, and by arranging the overflow port 116 downward and arranging the overflow channel 17 on the outer side of the second partition 152, the odor entering from the overflow port 116 needs to pass through the overflow channel 17 and then bend to flow into the water seal structure 15, instead of rushing directly to the water seal structure 15, that is, increasing the bending path of the odor can hinder the flow of the odor into the water tank 1.
[0040] In an exemplary embodiment, the water seal structure 15 further includes a bottom plate 154 sealingly disposed at the bottom of the first partition plate 151 and the second partition plate 152, and the bottom plate 154 is higher than the bottom of the water storage chamber 118. By providing the bottom plate 154, the water seal chamber 157 of the water seal structure 15 can be disposed at a preset height of the water tank, rather than at the bottom of the water tank, because the depth of the water seal chamber 157 does not need to be too deep, as long as the water seal is satisfied.
[0041] In an exemplary embodiment, the water seal structure 15 also includes a third partition 153 extending downward from the top plate of the box body 11, and the third partition 153 is configured to extend into the water in the water seal cavity 157 to separate the overflow port 116 from the water storage cavity 118 from above the water in the water seal cavity 157.
[0042] refer to Figure 4-Figure 6 In the example shown, an escape recess 117 is formed above the water tank 11, and the escape recess 117 is used to avoid the structure of the toilet, such as a toilet bowl, when installed on the toilet, and a water seal structure 15 is provided near one side of the box body 11. In order to facilitate the formation of the water seal structure inside the box body, an opening and a sealing plate 14 for sealing the opening are provided at the top of the box body 11, and a first sealing ring 141 is provided between the sealing plate 14 and the box body 11 to seal the opening.
[0043] In this example, the water seal structure 15 includes a main plate 156, a first partition plate 151, a second partition plate 152, a third partition plate 153, a bottom plate 154 and a second sealing ring 155. The main plate 156 is fixedly connected to the top plate and the side wall of the box body 11. The first partition plate 151, the second partition plate 152, the third partition plate 153 and the bottom plate 154 are all fixed on the main plate 156. The bottom plate 154 is located at the bottom of the first partition plate 151 and the second partition plate 153 and is sealed by the second sealing ring 155. Among them, the main plate 156, the first partition plate 152, the second partition plate 152 and the bottom plate 154 and the side wall of the box body 11 together form a water seal cavity 157, and the third partition plate 153 extends downward from the top of the box body 11 into the water seal cavity 157. In this way, a channel connecting the water storage cavity 118 and the overflow port 116 is formed under the third partition plate 153. The water in the water storage cavity 118 can flow to the overflow port 116 through the channel. When there is water in the water seal cavity 157 under the third partition plate 153, the channel can be water-sealed to prevent the odor entering from the overflow port 116 from flowing into the water tank.
[0044] In addition, to facilitate the forming of the water tank 1, the box body 11 is configured to include an upper box body 111 and a lower box body 112, which are buckled and connected to form the box body 11. A fixing plate 13 can be fixed at the bottom of the lower box body 112, and the fixing plate 13 is used to install the water tank 1 on the toilet.
[0045] It is understandable that the structure of the box body 11 can be adaptively modified according to the installation position of the toilet or other needs, and the water seal structure 15 can also have various deformations and is not limited to the above-mentioned settings.
[0046] In one embodiment, the water tank 1 further comprises a liquid level gauge 12 disposed on the tank body 11, and the liquid level gauge 12 is configured to detect the water level in the water storage chamber 118. The water level detected by the liquid level gauge 12 can control the water inlet assembly to enter the water storage chamber 118.
[0047] In one embodiment, the water tank 1 further comprises a water pump 16 disposed in the water storage chamber 118, a water pumping pipe 161 is disposed at the water inlet end of the water pump 16, and a water outlet end of the water pump 16 is connected to the water outlet 114 of the box body 11; wherein a groove 1181 is disposed at the bottom of the box body 11 (refer to Figure 7 ), the groove 1181 can be formed by the bottom of the box body 11 being recessed downward, and the recessed downward will form a convex portion 119 at the bottom of the box body 11 (refer to Figure 4 and Figure 5 ), the end of the water pumping pipe 161 is located in the groove 1181, so that the water pumping pipe 161 can easily draw water from the water storage chamber 118.
[0048] In one embodiment, a vent 115 may be further provided on the box body 11. Ventilation of the water tank 1 through the vent 115 can balance the internal and external pressures, thereby preventing the water from being unable to enter the water tank 11 due to excessive pressure.
[0049] The embodiment of the present application also provides a toilet water channel structure, such as Figure 8 As shown, it includes a water inlet assembly 3, an anti-siphon device 4 and the water tank 1 as described above; wherein the water inlet assembly 3 is connected to the water inlet of the anti-siphon device 4, and the water outlet of the anti-siphon device 4 is connected to the water inlet 113 of the water tank 1. The water inlet assembly 3 and the anti-siphon device 4 can be installed on the base assembly 7 of the toilet. The anti-siphon device 4 is set to prevent the water from flowing back into the water inlet assembly 3 due to negative pressure in the water inlet assembly 3, thereby polluting the water source. The embodiment of the present application can adopt the anti-siphon device in the prior art, and its structure is not described in detail here.
[0050] In one example, reference Figure 8 The water inlet assembly 3 includes a first water pipe 31, and may also include switch components such as a solenoid valve for controlling water inlet. The first water pipe 31 is connected to the water inlet of the anti-siphon device 4, and the water outlet of the anti-siphon device 4 is connected to the water inlet 113 of the water tank 1 through the second water pipe 5.
