[0026] Example
[0027] Reference Figure 1-Figure 5The utility model provides a technical solution: a water dispenser with controllable flow, comprising a body 1 and a flow control mechanism 3, a control switch 2 is installed on the body 1, the flow control mechanism 3 comprises a hollow bin 31, the hollow bin 31 is stably installed inside the body 1, a water collecting bin 311 is slidably installed inside the hollow bin 31, a pressure sensor 32 is installed at the inner bottom of the hollow bin 31 and corresponds to the position of the water collecting bin 311, a water pipe 331 is installed outside the water collecting bin 311, and a first electronic control valve 33 is arranged on the water pipe 331.
[0028] In a preferred embodiment, a plurality of control buttons 4 are installed on the outside of the body 1, and the control buttons 4 are electrically connected to the PLC controller 5, and the PLC controller 5 is electrically connected to the pressure sensor 32 and the first electronic control valve 33. In order to save water resources, this device selects a suitable amount of water when receiving water, and sets the water amount to multiple types, 100ml, 200ml, 300ml and 500ml. Choose a suitable amount of water according to the capacity of your cup. When the released water volume reaches the set value, the waterproofing will stop, thereby avoiding the waste of water resources. Therefore, the first electronic control valve 33 is electrically connected to the PLC controller 5 to realize automatic opening and closing of the water pipe 331 to meet the use requirements.
[0029] In a preferred embodiment, two control switches 2 are provided, one for controlling hot water and the other for controlling water at room temperature. Two control switches 2 are provided to control hot water and water at room temperature respectively, so as to avoid water flowing out randomly and causing waste.
[0030] In a preferred embodiment, several control buttons 4 are respectively set to 100ml button, 200ml button, 300ml button and 500ml button, and the control buttons 4 are respectively set in the hot water area and the normal temperature water area. When collecting water, choose the appropriate amount of water according to the capacity of your own water cup. Setting the control buttons 4 in the hot water area and the normal temperature water area can meet the use of different people. No matter whether you are collecting hot water or normal temperature water, you can choose the amount of water to release, thereby achieving the effect of saving water resources.
[0031] This device allows water to flow into the interior of the water collecting bin 311, and determines the amount of water released by bearing the weight of the water collecting bin 311. In order to ensure the stable use of the water collecting bin 311, the hollow bin 31 is fixedly installed inside the body 1 through the support rod 6, and a limit rod 7 is fixedly installed inside the hollow bin 31. A sliding plate 8 is provided on the outer surface of the water collecting bin 311. The limit rod 7 penetrates the interior of the sliding plate 8 and makes the sliding plate 8 slide. A limit rod 7 is installed inside the hollow bin 31, and the limit rod 7 penetrates the sliding plate 8 on the outer surface of the water collecting bin 311, so that the water collecting bin 311 can always move up and down and can move stably. As the water inside the water collecting bin 311 continues to increase, the water collecting bin 311 will move downward, increasing the squeezing pressure on the pressure sensor 32, and the amount of water released can be obtained according to the size of the squeezing pressure.
[0032] In order to achieve quantitative water discharge, the present device adopts a two-time water discharge method. For the first water discharge, a water box 9 is installed inside the machine body 1. The bottom of the water box 9 is connected to a pipe 10. One end of the pipe 10 is arranged inside the water collecting bin 311. A second electronic control valve 11 is installed outside the pipe 10. The second electronic control valve 11 is electrically connected to the PLC controller 5. After the water volume is selected, the PLC controller 5 controls the second electronic control valve 11 to open, so that the water inside the water box 9 is transported to the inside of the water collecting bin 311. This is the first water discharge. The purpose is to weigh the water through the water collecting bin 311 so as to discharge a certain amount of water to prevent waste.
[0033] After the water in the water box 9 is transported to the water collecting bin 311, it is discharged from the water collecting bin 311 to achieve water discharge. However, since the water collecting bin 311 is rectangular in shape, the water in the water collecting bin 311 cannot be completely discharged, and some water will remain in the water collecting bin 311. When the water dispenser is not used for a period of time, bacteria are likely to grow inside the water collecting bin 311, thereby affecting its use. To avoid bacterial growth, a pumping mechanism 12 is installed on the body 1. The pumping mechanism 12 includes a suction pipe 121, a sliding plug 122, a drain pipe 123 and a pull rod 124. The suction pipe 121 passes through the outer surface of the body 1 and is fixedly installed inside the body 1. One end of the suction pipe 121 is placed inside the water collecting bin 311, and the outer surface of the suction pipe 121 is connected to the drain pipe 123. The interior of the suction pipe 121 is slidably connected to the sliding plug 122, and the sliding plug 122 is fixedly connected to the pull rod 124, and a disc 13 is installed on one end of the pull rod 124.
[0034] When the water dispenser stops being used and has not been used for a period of time, the pull rod 124 can be pulled, and the movement of the pull rod 124 can drive the sliding plug 122 to move inside the water suction pipe 121, so that a negative pressure is formed inside the water suction pipe 121. At this time, the water retained in the water collection bin 311 will be sucked into the water suction pipe 121, and the water will be transported inside the water suction pipe 121. When the water is transported to the position of the drain pipe 123, the water will enter the drain pipe 123, thereby discharging the water.
[0035] In order to ensure the formation of negative pressure inside the water suction pipe 121, the device uses a sealing plug to block one end of the drain pipe 123 in daily use, so as to prevent the outside air from being sucked into the water suction pipe 121 during drainage. When the sliding plug 122 cannot be moved during drainage operation, the sealing plug can be removed, and the water in the drain pipe 123 will be automatically discharged, thereby discharging the water retained in the water collection bin 311, and the inside of the water collection bin 311 will dry out in a short time to prevent the growth of bacteria.
[0036] Specifically, the working process or working principle of a water dispenser with controllable flow rate is: when people need to drink water, they hold a cup and place it at the water inlet, then turn on the switch to release the bottled water, and the water flows directly into the cup. However, in real life, people often play with their mobile phones, whether they are eating or resting, so when getting water, some people will play with their mobile phones while getting water. When they are fascinated by playing with their mobile phones, they ignore the fact that the cup is getting water, and thus they will not observe the water getting situation, which easily causes the water inside the cup to overflow. Even if the person getting the water finds it later, the water has already overflowed from the cup, resulting in a waste of water. Therefore, this device is designed to solve this problem.
[0037] When using the device, bottled water is placed on the body 1, and the bottled water is released for drinking. In order to avoid water waste, the device selects a suitable waterproof amount according to the capacity of one's cup when releasing water. For example, 100 ml of water needs to be released. According to whether one drinks hot water or room temperature water, press the corresponding button, and the PLC controller 5 controls the second electronic control valve 11 to open, release the water in the water box 9, and put it into the corresponding water collecting bin 311. 100 ml of water is about 100 g, so the water in the water box 9 is transported to the water collecting bin 311 through the pipe 10. As the amount of water in the water collecting bin 311 continues to increase, the water collecting bin 311 will be weighted, thereby squeezing the pressure sensor 32. When the pressure sensor 32 detects that the pressure value is 100 g, the second electronic control valve 11 can be controlled to close through the PLC controller 5 to stop the continued transportation of water.
[0038] Then, the first electronic control valve 33 is controlled to open through the PLC controller 5, so that the water inside the water collection bin 311 can be transported to the inside of the water pipe 331. The control switch 2 of the device is set on the water pipe 331. The water receiver only needs to open the control switch 2 to release the water inside the water collection bin 311, and the water volume inside the water collection bin 311 is the water volume selected by the water receiver. Even if the waterproof status is not observed, the water will not overflow, thereby saving water resources.
[0039] In reality, the water pipe 331 cannot release all the water inside the water collection bin 311, and a small amount of water will remain at the bottom of the water collection bin 311. When the water dispenser is not used for a period of time, such as during holidays, the bottom of the water collection bin 311 is wet and it is easy to breed bacteria if it is not used for a period of time. Therefore, when the water dispenser is not to be used, the pull rod 124 is pulled to drive the sliding plug 122 to move outward inside the water suction pipe 121. At this time, the water suction pipe 121 will form a negative pressure, which can press the water inside the water collection bin 311 into the inside of the water suction pipe 121. When the water flows inside the water suction pipe 121, it will be discharged through the drain pipe 123. In this way, the water inside the water collection bin 311 is treated, so that the inside of the water collection bin 311 becomes dry in a short time to avoid the breeding of bacteria, and the machine body 1 can be used directly later.
[0040] It should be noted that the pressure sensor 32 and the PLC controller 5 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
