As shown in fig. 1 to 4, an embodiment of the present invention provides a water tank, which includes a water tank main body 1 having a water containing cavity 11 and an overflow protection structure 2 connected to the water tank main body 1.
The tank body 1 has a tank outlet 12 communicating with the water containing chamber 11.
The overflow protection structure 2 comprises a housing 21, a draft tube 22, an overflow port 23 and a water inlet pipe head 24.
The case 21 is mounted on the tank main body 1, and the inlet pipe head 24 is mounted on the case 21.
The guide tube 22 is arranged in the shell 21, and the water inlet tube head 24 is communicated with the water containing cavity 11 through the guide tube 22.
A water flow channel 25 for communicating the overflow port 23 and the water containing cavity 11 is formed between the draft tube 22 and the housing 21.
The utility model provides a water tank mainly used closestool in. The water tank comprises a water tank body 1 and an overflow protection structure 2. The tank body 1 has a water containing chamber 11 therein, and a tank outlet 12 at the lower half or bottom thereof. The water outlet 12 of the water tank is used for connecting with a water-using appliance.
The overflow protection structure 2 is installed on the tank body 1 to prevent water leakage of the toilet bowl caused by water overflow of the tank.
The overflow protection structure 2 comprises a shell 21, a draft tube 22, an overflow port 23 and a water inlet pipe head 24.
The upper part of the water tank body 1 is provided with a water tank inlet, and the shell 21 is arranged at the water tank inlet. The draft tube 22 is installed in the housing 21, a water flow passage 25 is formed between the draft tube 22 and the housing 21, and a lower end opening of the water flow passage 25 communicates with the water containing chamber 11. The overflow port 23 is provided at one side of the housing 21 between the upper and lower ends of the draft tube 22. The overflow port 23 is communicated with the water containing cavity 11 through a water flow channel 25. A water inlet nipple 24 is mounted on the housing 21 and is connected to a water inlet pipe of the toilet for supplying water into the water tank. The lower end of the draft tube 22 is communicated with the water containing cavity 11, and the water inlet tube head 24 is communicated with the water containing cavity 11 through the draft tube 22. The guide pipe 22 is used for guiding the water in the water inlet pipe head 24 to the water containing cavity 11.
The utility model provides a water tank, its honeycomb duct 22 do not directly communicate with overflow mouth 23, and overflow mouth 23 passes through rivers passageway 25 and holds the water cavity 11 intercommunication.
In normal state, water flows into the water containing cavity 11 through the water inlet pipe head 24 and the guide pipe 22, and then is discharged to the water using appliance through the water tank outlet 12.
When an abnormal condition occurs (for example, the water outlet 12 of the water tank is blocked or the water inlet pipe head 24 cannot be closed), the water level in the water containing cavity 11 is increased, and the water in the water containing cavity 11 can be discharged through the water flow channel 25 and the overflow port 23, so that the water is prevented from being discharged from the flow guide pipe 22. In this process, the flow direction of water can be referred to as arrow a in fig. 4. In the process, the water falling from the water inlet pipe head 24 impacts the water in the flow guide pipe 22, the speed energy of the water flow is converted into pressure energy, the water level of the flow guide pipe 22 is reduced, and the water leakage of the toilet caused by the overflow of the water tank is avoided. Specifically, the water level line in the water inlet pipe head 24 is B, and the water level line in the draft tube 22 is C, and obviously, the water level line C is significantly lower than the water level line B, so that water can be effectively prevented from being discharged from the upper end of the draft tube 22.
In one embodiment, as shown in fig. 2-4, the water intake tip 24 is positioned above the draft tube 22, and the tip outlet 241 of the water intake tip 24 is directed toward the upper end of the draft tube 22.
A preset distance is arranged between the tube head water outlet 241 and the upper end of the guide tube 22.
Through arranging tube head delivery port 241 and honeycomb duct 22 interval, not direct connection can have the impact when making water flow downwards, does benefit to and pushes down the water level in the honeycomb duct 22.
The preset distance can be specifically set according to needs, for example: the preset distance is set as L0L is more than or equal to 5mm0≤100mm。
In one embodiment, as shown in FIGS. 2-4, the draft tube 22 extends vertically within the housing 21. The downward projection of the tip water outlet 241 falls into the draft tube 22.
That is, the cross-sectional area of the flow guide tube 22 is larger than the area of the tube head water outlet 241, and the tube head water outlet 241 is located right above the flow guide tube 22, so as to ensure that the water flowing from the tube head water outlet 241 falls into the flow guide tube 22 as much as possible.
In one embodiment, the area of the outlet 241 of the cartridge is S1The cross-sectional area of the draft tube 22 is S2. Then, 1 is less than or equal to S2/S1≤4。
So set up, both can guarantee from the water that falls in the tube head delivery port 241 get into the honeycomb duct 22, can avoid again influencing the impulsive force of the water of whereabouts because of honeycomb duct 22 is too thick, can make the water that falls have continuous pressure to the surface of water, be favorable to reducing the water level in the honeycomb duct 22.
In one embodiment, as shown in FIG. 3, the upper end of the draft tube 22 has a flared draft tube 26. The radius of the draft tube 26 becomes gradually smaller in the direction from the top to the bottom. The tip outlet 241 is directed toward the drain tube 26.
The trumpet-shaped drainage tube 26 is connected or installed at the upper end of the drainage tube 22, and the tube head water outlet 241 faces the drainage tube 26, so that the water falling from the tube head water outlet 241 is favorably received, the water is smoothly drained into the drainage tube 22, and the waste of the water is avoided.
In one embodiment, as shown in FIG. 3, the upper end of the draft tube 26 has a water retaining ring 27.
By installing or connecting the water guard ring 27 at the upper end of the drain tube 26, it is possible to prevent water from splashing to the outside after contacting the drain tube 26.
In one embodiment, the water deflector ring 27 and the draft tube 26 are integrally formed with the draft tube 22.
The water retaining ring 27, the drainage tube 26 and the flow guide tube 22 are all plastic parts and can be integrally formed in an injection molding mode, the structural strength is high, and the processing and forming are convenient.
In one embodiment, as shown in fig. 1-3, the inlet stub 24 is supported on the housing 21 by a connector 28.
The connector 28 may be a bolt, a connecting rod, or the like, which facilitates installation, replacement, and maintenance of the inlet stub 24.
In one embodiment, the tip outlet 241 has a water flow separation feature therein.
The water flow separation structure can be ribs or holes arranged in the water outlet 241 of the tube head, and can divide water flow into strands so as to realize different water supply requirements.
In one embodiment, the length of the draft tube 22 is L1Wherein L is not less than 5mm1Less than or equal to 500 mm. The longer the length of the draft tube 22 is, the larger the impact force of the falling water in the draft tube 22 is, which is beneficial to reducing the water level in the draft tube 22, and can effectively prevent the water from being discharged from the upper end of the draft tube 22, thereby avoiding the water leakage of the toilet caused by the overflow of the water tank. To sum up, the utility model provides a water tank can effectively prevent the water tank overflow, need not to reduce the water intake velocity of closestool, has improved user's use and has experienced.
