[0001] The invention relates to the technical field of water dispensers, in particular to a self-sensing quantitative water-discharging direct drinking water dispenser. Background Art

[0002] The built-in high-efficiency filtration system of the direct drinking water machine can effectively remove impurities, bacteria, viruses, heavy metals and other harmful substances in the water, ensure the safety and purity of drinking water, and provide users with safe and convenient drinking water services. It can be seen in homes or some public places. With the continuous advancement of technology, direct drinking water machines with automatic sensing water outlets have gradually appeared. There is no need to manually operate buttons or switches. Just put the cup in the corresponding position to automatically dispense water. The water output can be set according to demand, which is more convenient to use.

[0003] However, while this type of direct drinking water machine is convenient to use, it also has certain safety hazards. When objects other than cups are placed in the designated position, such as when children place toys underneath, the direct drinking water machine may not be able to identify whether the object placed underneath is a cup and will still automatically dispense water. If the water discharged from the water outlet is hot water at this time, it may cause scalding to the child. In addition, there is a certain space between the cup mouth and the water outlet. During the water dispensing process, once the child's hand reaches the lower end of the water outlet, it is easy to cause scalding.

[0004] Based on the above situation, it is necessary to design a self-sensing quantitative water outlet direct drinking water machine to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0018] Reference Figure 1-Figure 10As shown, a self-sensing quantitative water-discharging direct drinking water machine includes a machine body 1, a water-discharging control component, a protective cover 3 and a controller 4. The machine body 1 is provided with a hot and cold water supply component for discharging water, which can discharge hot water and cold water according to user needs. It is also provided with a water-discharging control component, which includes a radar sensor 2 installed above the machine body 1, a reed switch 21 installed below the water cup placement position and an electromagnetic valve 22 arranged on the hot and cold water supply component. When the radar sensor 2 detects the presence of an object such as a cup, a signal will be transmitted to the controller 4. At the same time, the reed switch 21 will also transmit a signal to the controller 4 after being connected. After receiving the two sets of signals from the radar sensor 2 and the reed switch 21, the controller 4 will control the electromagnetic valve 22 to open for water discharge, thereby avoiding the phenomenon of misjudgment caused by starting the electromagnetic valve 22 after receiving a single signal from the radar sensor 2 or the reed switch. For example, if a cup is temporarily placed above the machine body 1, a signal will be transmitted to the controller 4. The box body is mistakenly detected as a water cup by the radar sensor 2, and the water outlet control component also includes an elastic tube installed below the water cup placement on the body 1, the elastic tube includes a top tube 11 and a bottom tube 12, the reed switch 21 is installed in the bottom tube 12, and a magnetic plate is provided at the bottom of the top tube 11, and a spring 13 is connected between the top tube 11 and the bottom tube 12. When the water cup is placed at the water cup placement on the body 1, the water cup will be pressed down on the top tube 11 under the action of its own gravity. At this time, the top tube 11 compresses the spring 13 downward to drive the magnetic plate downward and approach the reed switch 21. The two reeds in the reed switch 21 will attract and turn on the circuit. At this time, the controller 4 will receive the signal of the reed switch 21. Therefore, even if the radar sensor 2 detects the presence of the water cup, the reed switch 21 is not turned on, indicating that the water cup may not be placed in the specified position, so the controller 4 will not control the solenoid valve 22 to open for water discharge.

[0019] In order to prevent children from putting their hands under the water outlet pipe of the machine body 1 during play and causing burns, a connecting frame is provided inside the machine body 1, and a protective cover 3 is connected to the bottom of the connecting frame through a telescopic member 31 for protection during water outlet. The telescopic member 31 can be an electric telescopic rod or other device. The protective cover 3 can be a circle or square with a larger diameter. When the protective cover 3 falls, it can protect the outside of the cup. When the radar sensor 2 and the reed switch 21 both generate electrical signals and transmit the signals to the controller 4, the controller 4 will control the telescopic member 31 to extend and drive the protective cover 3 to move downward. , for protection, a quantitative water outlet component is also provided in the hot and cold water supply component, the quantitative water outlet component includes a flow meter 5 for detecting the output water volume and is electrically connected to the controller 4, the controller 4 controls the telescopic member 31 to close the flow meter 5 according to the signal when the flow meter 5 is closed, after the water outlet is completed, the solenoid valve 22 is closed, and the detection signal of the flow meter 5 disappears, at this time, the controller 4 controls the telescopic member 31 to drive the protective cover 3 to move upward, release the protection, and facilitate the removal of the water cup after the water is received, and the protective cover 3 is a hollow structure to avoid the presence of water vapor in the protective cover 3 when receiving hot water, which makes it inconvenient to observe the water receiving situation.

[0020] Reference Figure 7 As shown, further, it also includes a preliminary warning component, which includes a warning piece 6 and a first pressure sensor 61 arranged at the lower end of the protective cover 3. The controller 4 controls the operation of the warning piece 6 according to the signal of the first pressure sensor 61. When the telescopic piece 31 drives the protective cover 3 to move downward, if there is an object on the part of the body 1 where the cup is placed, such as a child's hand or other items placed thereon, the first pressure sensor 61 will conflict with the object and generate a pressure signal. At this time, the controller 4 starts the warning piece 6 to sound an alarm according to the pressure signal of the first pressure sensor 61, wherein the warning piece 6 can be a buzzer or a warning light, or a warning device combining a light and a sound, to remind the surrounding people, draw attention, and reduce the risk of scalding. When the telescopic piece 31 drives the protective cover 3 to move downward to the extreme state, the first pressure sensor 61 fits with the body 1, so that the first pressure sensor 61 will not be pressurized to generate a pressure signal.

[0021] Reference Figure 7As shown, further, a buffer member 32 is slidably connected to the lower end of the protective cover 3, and a first pressure sensor 61 is installed below the buffer member 32. A second pressure sensor 33 is provided between the protective cover 3 and the buffer member 32, and an emergency stop switch 34 electrically connected to the controller 4 is also provided on the body 1. When an object is placed on the water cup on the body 1 or a child places his hand on it when playing, the buffer member 32 will first contact the object placed below, and as the telescopic member 31 drives the protective cover 3 to continue to move downward, the protective cover 3 will be blocked by the object and will not continue to move downward, but the continued downward movement of the protective cover 3 will gradually reduce the gap between the two. When the second pressure sensor 33 is squeezed between the protective cover 3 and the buffer member 32, the second pressure sensor 33 generates a pressure signal and transmits it to the controller 4. The controller 4 activates the emergency stop switch 34 to stop the telescopic member 31 from driving the protective cover 3 to move downward, and will not open the solenoid valve 22 to discharge water, thereby avoiding safety hazards such as pressure on children's hands caused by the downward movement of the protective cover 3.

[0022] Among them, refer to Figure 6As shown, the hot and cold water supply assembly includes a first water tank 7 and a second water tank 71. A heating element 72 such as a heating pipe is provided inside the second water tank 71 for heating the direct drinking water, and a temperature sensor may be provided inside the second water tank 71. When the temperature sensor detects that the water level inside the second water tank 71 is lower than the set value, the heating element 72 is started for heating. The first water tank 7 and the second water tank 71 are connected to the external water supply pipe through a water delivery pipe 73. The water delivered through the water delivery pipe 73 is water that has been filtered by various filtering devices and can be directly drunk. When the water in the first water tank 7 or the second water tank 71 is drunk, new water will be introduced through the water delivery pipe 73 to ensure a continuous water supply. A hot water pipe 74 and a cold water pipe 75 are respectively connected to the first water tank 7 and the second water tank 71. The output ends of the hot water pipe 74 and the cold water pipe 75 are connected to a water outlet pipe 76 installed on the body 1. By uniformly discharging the cold water and the hot water through the water outlet pipe 76, and the protective cover 3 is located on the outer periphery of the water outlet pipe 76, only one protective cover needs to be provided. The protective cover 3 is sufficient, and there is no need to set a protective cover 3 on the cold water pipe 75 or the hot water pipe 74, which reduces the space occupation. In the limited space of the machine body 1, more water inlets may be set to facilitate multiple people to collect water at the same time, and an operation panel may be provided above the machine body 1. The controller 4 is also electrically connected to the data storage module 9. Before collecting water, the required water volume or the respective water volume of cold and hot water can be operated on the operation panel, such as 100ml, 200ml, 300ml and other gears, and the water-saving gear output by the user is stored in the data storage module 9, if the user inputs a hot water level of 100ml and a cold water level of 200ml, the solenoid valve 22 on the hot water pipe 74 will be closed after 100ml of hot water is discharged according to the detection of the flow meter 5, and the solenoid valve 22 on the cold water pipe 75 will be opened at the same time, and 200ml of cold water will flow out. During this process, the protective cover 3 remains in a descending state until the water discharge is completed, the flow meter 5 detection signal disappears, and the controller 4 controls the telescopic member 31 to drive the protective cover 3 to move upward, so that the cup after the water collection is completed can be taken away.

[0023] Further, see Figure 4 As shown, a reserved groove 8 is provided on the body 1 for the protective cover 3 to move up and down, a distance sensor 81 is provided on the inner top wall of the reserved groove 8, and an ultraviolet disinfection lamp 82 is provided at the lower end of the protective cover 3. When the protective cover 3 moves upward, the bottom end of the protective cover 3 is located at the outer periphery of the water outlet pipe 76. At this time, the distance sensor 81 detects that the protective cover 3 moves to a certain height above, and transmits a signal to the controller 4. The controller 4 controls the ultraviolet disinfection lamp 82 to turn on, and regularly disinfects the water inlet to prevent bacterial growth and be more hygienic. On the contrary, when the water is received, the protective cover 3 moves downward, and the distance sensor 81 detects that it is far away from the protective cover 3, then the ultraviolet disinfection lamp 82 is turned off.

[0024] Among them, such as at night or when the frequency of water collection is less, the protective cover 3 is always in the upper position, and the ultraviolet disinfection lamp 82 is also always turned on. In order to avoid the situation where the ultraviolet disinfection lamp 82 is always turned on and causes energy waste, a time detection module 83 electrically connected to the controller 4 is also included. The controller 4 controls the opening and closing of the ultraviolet disinfection lamp 82 according to the signal of the time detection module 83. A certain time can be set during the working time of the ultraviolet disinfection lamp 82, such as a timing of 30 minutes, etc. If the set time is exceeded, it will be turned off, and it will be turned on after being closed for a certain period of time to achieve intermittent work.
