Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] This utility model provides a water outlet device, for reference. Figure 1 and Figure 2 The system includes: a water tank 1, a water outlet 2 protruding from the water tank 1, and a water receiving platform 3 located below the water outlet 2, the water receiving platform 3 being used to place a water container; a distance sensor 4, the distance sensor 4 being arranged adjacent to the water outlet 2, the sensing area of ​​the distance sensor 4 at least partially covering the space between the water outlet 2 and the water receiving platform 3, used to sense the distance between the liquid surface in the water container and the distance sensor 4, when the distance between the liquid surface and the distance sensor 4 reaches a preset distance, the water outlet 2 stops discharging water, so as to realize automatic control of water discharging.

[0031] The distance sensor 4 includes a sensing element, which is equipped with a heating and light-transmitting plate. The heating and light-transmitting plate is spaced between the water receiving platform 3 and the sensing element. In this way, when the outlet water temperature is high, the heating and light-transmitting plate can be heated to prevent water vapor from condensing on the sensing element and effectively prevent water vapor from affecting the operation of the sensing element.

[0032] The water outlet device also includes a heat dissipation component 5. The heat dissipation area of ​​the heat dissipation component 5 at least partially covers the sensing element. In this way, the heat dissipation component 5 can blow away or absorb the water vapor near the sensing element, avoiding water vapor adhering to the sensing element and causing errors in the sensing information. This helps to improve the accuracy of the automatic water shut-off control of the water outlet device.

[0033] Specifically, the heat-generating light-transmitting plate is a light-transmitting material with a heat-generating function, including at least a heat-generating layer. The heat-generating layer is electrically connected to a power supply device, which raises the temperature of the heat-generating light-transmitting plate and prevents steam from condensing into water on the heat-generating light-transmitting plate.

[0034] In some embodiments, the distance sensor 4 further includes a housing with an opening structure, the sensing element is disposed in the inner cavity of the housing, and the heating and light-transmitting plate is disposed at the opening of the housing. In this way, water vapor can be prevented from entering the interior of the sensing element and causing damage to the sensing element; and steam can be prevented from condensing at the opening of the distance sensor 4, which would affect the sensing accuracy of the sensing element.

[0035] In some embodiments, the water outlet device further includes a first controller 9, which is electrically connected to both the heating and light-transmitting plate and the heat dissipation assembly 5. Thus, the first controller 9 can control the opening and closing of the heating and light-transmitting plate and the heat dissipation assembly 5. Specifically, the first controller 9 can also adjust the parameters of the heating and light-transmitting plate and the heat dissipation assembly 5. For example, the first controller 9 can control the heating temperature of the heating and light-transmitting plate, adjusting the temperature according to changes in ambient temperature and outlet water temperature to prevent steam condensation. For example, the first controller 9 can also control the heat dissipation efficiency and heat dissipation range of the heat dissipation assembly 5 to adapt the heat dissipation function to different environments.

[0036] In some embodiments, the water outlet device further includes a first temperature sensor 6, which is located near the sensing element and is used to collect the temperature of the sensing element. The temperature of the sensing element collected by the first temperature sensor 6 is the first collection temperature.

[0037] Specifically, the first temperature sensor 6 is electrically connected to the first controller 9 and can feed back the first collected temperature to the first controller 9. The first controller 9 determines whether the temperature near the sensor meets the conditions for steam condensation based on the first collected temperature, and then controls the opening and closing of the heat-generating light-transmitting plate and the heat dissipation component 5.

[0038] In some embodiments, the water outlet device further includes a second temperature sensor 7, which is located away from the water outlet 2 and is used to collect the ambient temperature. The ambient temperature collected by the second temperature sensor 7 is the second collection temperature.

[0039] Specifically, the second temperature sensor 7 is electrically connected to the first controller 9 and can feed back the second collected temperature to the first controller 9. The first controller 9 can determine whether the ambient temperature meets the conditions for steam condensation based on the second collected temperature, and is used to control the opening and closing of the heat-generating light-transmitting plate and the heat dissipation component 5.

[0040] In some embodiments, the water outlet device includes at least a first temperature sensor 6 and a second temperature sensor 7. The first temperature sensor 6 and the second temperature sensor 7 are electrically connected to the first controller 9, and can feed back the first collected temperature and the second collected temperature to the first controller 9. The first controller 9 compares the absolute value of the difference between the first collected temperature and the second collected temperature with a first preset temperature to determine whether the conditions for steam condensation are met, and then controls the opening of the heating and light-transmitting plate and the heat dissipation component 5.

[0041] In some embodiments, the water outlet device further includes a body 10, which includes a receiving cavity capable of accommodating the water tank 1, the first controller 9, and the water pipes connected to the water tank 1 and the wiring connected to the first controller 9. The body 10 can provide structural support and protect the internal components, water pipes, water tank 1 and other components from external physical damage.

[0042] Specifically, the exterior of the body 10 is provided with a water receiving area, which includes a baffle between the water tank 1 and the water outlet 2, and a top wall opposite to the water receiving platform 3. The water receiving area is located directly below the water outlet 2.

[0043] Specifically, it also includes an operation display screen 8 disposed on the outside of the body 10. The operation display screen 8 is electrically connected to the first controller 9. Thus, the operation display screen 8 can be used to display various parameters received by the first controller 9, and the parameters of the first controller 9 can be adjusted through the operation display screen 8. For example, the above parameters may include the outlet water temperature, ambient temperature, the height of the water container, and the liquid level in the water container.

[0044] Specifically, the operation display screen 8 may include a parameter display module, a parameter input module, and an information conversion module. The parameter display module is connected to the signal conversion module and can display the signal information of the signal conversion module on the screen of the operation display screen 8. The parameter input module is connected to the signal conversion module and can transmit the input parameters to the first controller 9 through the signal conversion module.

[0045] In some embodiments, the heat dissipation component 5 includes a drive device and a cooling fan. The cooling fan is driven and connected to the drive device, which is electrically connected to a first controller 9. The first controller 9 can control the opening and closing of the heat dissipation component 5 and can control the speed of the cooling fan, thereby controlling the heat dissipation efficiency of the cooling fan. Specifically, the cooling fan can be at least one of a blower fan and a suction fan.

[0046] Specifically, the body 10 is provided with a vent, and the heat dissipation component 5 is disposed in the vent. Understandably, the size and position of the vent are adapted to the size and position of the heat dissipation component 5, effectively dissipating the heat generated during the operation of the heat dissipation component 5. Specifically, the sensor is disposed on the top wall of the water-receiving area, and the vent is disposed on the side wall of the water-receiving area, such that the heat dissipation area of ​​the heat dissipation component 5 at least partially covers the sensor, and dissipates the heat generated by the heat dissipation component 5 in a direction away from the water-receiving area. Exemplarily, the heat dissipation component 5 includes a suction fan, the vent is disposed on the side wall of the water-receiving area, and the suction fan is disposed in the vent and rotates relative to the vent, thus allowing the suction fan to dissipate the absorbed heat through the vent. Understandably, the vent can also be disposed on the top wall of the water-receiving area, as long as the heat dissipation component 5 can reduce water vapor on the sensor; this invention does not impose any limitations on this.

[0047] In some embodiments, a hot water button is provided on the exterior of the body 10, and the hot water button is electrically connected to the first controller 9. When the user presses the hot water button, the first controller 9 receives the activation signal from the hot water button. The first controller 9 can control the heating and light-transmitting plate to start preheating, so that the heating and light-transmitting plate reaches a second preset temperature before the hot water is dispensed from the water outlet device, avoiding water vapor condensation caused by the heating and light-transmitting plate not heating up in time, which would affect the operation of the distance sensor 4. Specifically, the hot water button can be a touch-sensitive hot water button, which is set on the operation display screen 8.

[0048] Specifically, the water outlet device also includes a heating device that can heat the water in the water tank 1. The heating device is connected to the first controller 9, which can control the heating temperature of the heating device and thus control the temperature of the hot water in the water tank 1.

[0049] Specifically, a third temperature sensor is installed in the water tank 1 to collect the temperature of the hot water in the water tank 1. The third temperature sensor is connected to the first controller 9. The first controller 9 can transmit the third temperature collected by the third temperature sensor to the operation display screen 8. The user can also set the target temperature through the operation display screen 8 and control the heating device to turn on through the first controller 9 so that the water in the water tank 1 is heated to the target temperature.

[0050] In some embodiments, the water outlet device further includes a second controller, which is disposed between the water tank 1 and the water outlet 2. The second controller can be used to control the connection and closure between the water tank 1 and the water outlet 2. The second controller is electrically connected to the distance sensor 4, which transmits the collected distance signal to the second controller. The second controller can control the water outlet state of the water outlet 2 according to the liquid level in the water container.

[0051] In some embodiments, a water dispensing button is provided on the exterior of the body 10, and the water dispensing button is electrically connected to the distance sensor 4 and the second controller. When the user presses the water dispensing button, the second controller controls the water tank 1 to be in a passage with the water outlet 2, and the water in the water tank 1 flows out through the water outlet 2. The distance sensor 4 begins to collect distance information between itself and the water container and feeds this distance information back to the second controller. Specifically, the water dispensing button can be a touch-sensitive water dispensing button, which is set on the operation display screen 8.

[0052] In some embodiments, the sensing element includes at least a first sensing element, which is positioned near the water outlet 2. The first sensing element can detect a first distance between itself and the liquid surface in the water container. Understandably, as the amount of water in the container increases, the first distance between the first sensing element and the liquid surface decreases. Specifically, the first sensing element is electrically connected to a second controller. The first sensing element feeds back the detected first distance to the second controller. When the first distance is less than a first preset distance, the second controller can control the connection between the water tank 1 and the water outlet 2 to close, and the water outlet 2 stops discharging water. Understandably, the first preset distance can be set according to the actual application scenario, and will not be elaborated here.

[0053] In some embodiments, the sensing element includes at least a second sensing element, which is positioned near the water outlet 2. A second distance exists between the second sensing element and the highest point of the water container; this second distance varies with the height of the water container. Specifically, the second sensing element is electrically connected to a second controller. The second sensing element feeds back the collected second distance to the second controller. When the water container is placed on the water receiving platform 3, the second distance is less than a second preset distance. When the user moves the water container away, the second distance becomes greater than or equal to the second preset distance, and the second controller controls the water outlet 2 to stop discharging water. It is understood that the second preset distance can be set according to the actual application scenario, and will not be elaborated upon here.

[0054] In one embodiment, the sensing element includes at least a first sensing element and a second sensing element. The first and second sensing elements are electrically connected to a second controller. The first sensing element is at a first distance from the liquid surface in the water container, and the second sensing element is at a second distance from the highest point of the water container. The first and second sensing elements can respectively feed back the collected first and second distances to the second control device. When the absolute value of the difference between the first and second distances is less than or equal to a third preset distance, the second control device can control the water outlet 2 to stop discharging water. Understandably, the third preset distance can be set according to actual application conditions, and will not be elaborated here.

[0055] In some embodiments, the sensing element may include at least two first sensing elements and at least two second sensing elements, which can collect multiple first distances and multiple second distances, thereby improving the accuracy of the distance sensor 4.

[0056] In some embodiments, a water storage tank is provided below the water receiving platform 3, and a perforated plate is provided between the water receiving platform 3 and the water storage tank, so that the water on the water receiving platform 3 can flow into the water storage tank through the perforated plate, thus preventing water accumulation on the water receiving platform 3; specifically, the water storage tank can be connected to the outside of the water outlet device through a drain pipe to discharge the sewage in the water outlet tank.

[0057] In some embodiments, the water outlet device further includes a water purifier, which includes a filtration system capable of effectively purifying the water to be used in the water tank 1; in one example, the filtration system is disposed in the water tank 1; in another example, the filtration system is disposed between the water tank 1 and the water outlet 2. This helps to ensure the cleanliness and hygiene of the water source in the water outlet device, making the water outlet device suitable for various usage environments and improving its applicability and safety.

[0058] In some embodiments, a handle is provided on the left and right end faces of the exterior of the body 10 to facilitate the handling of the water outlet device.

[0059] The following combines the above Figure 1 and Figure 2 Specific embodiments of this utility model are introduced below. The technical solution of this utility model is described in more detail in the following embodiments. These embodiments are for illustrative purposes only, as various modifications and variations will be apparent to those skilled in the art within the scope of the disclosure of this application.

[0061] This embodiment provides a water outlet device, see reference. Figure 1 and Figure 2 It includes a body 10, a first controller 9, a second controller, a water tank 1, a water outlet 2 protruding from the water tank 1, and a water receiving platform 3 located below the water outlet 2. The body 10 is used to house the water tank 1 and the first controller 9. The second controller is located between the water tank 1 and the water outlet 2 and is used to control the water outlet 2's water output status.

[0062] The water outlet device also includes a distance sensor 4, which is arranged adjacent to the water outlet 2. The sensing area of ​​the distance sensor 4 at least partially covers the space between the water outlet 2 and the water receiving platform 3, and is used to sense the distance between the liquid level in the water container and the distance sensor 4, so as to realize automatic control of water outlet.

[0063] The distance sensor 4 includes a sensing element, which is equipped with a heating and light-transmitting plate. The heating and light-transmitting plate is spaced between the water receiving platform 3 and the sensing element. It can heat up the water by heating the light-transmitting plate, thus preventing water vapor from condensing on the sensing element and effectively preventing water vapor from affecting the operation of the sensing element.

[0064] Specifically, the sensing element includes at least a first sensing element and a second sensing element. The first sensing element and the second sensing element are electrically connected to the second controller. The first sensing element has a first distance from the liquid surface in the water container, and the second sensing element has a second distance from the highest point of the water container. The first sensing element and the second sensing element can respectively feed back the collected first distance and the second distance to the second control device.

[0065] The water outlet device also includes a heat dissipation component 5. The heat dissipation area of ​​the heat dissipation component 5 at least partially covers the sensing element, which can blow away or absorb water vapor near the sensing element, prevent water vapor from adhering to the sensing element and causing errors in the sensing information, and help improve the accuracy of the automatic water stop control of the water outlet device.

[0066] Specifically, the water outlet device also includes a first temperature sensor 6 and a second temperature sensor 7. The first temperature sensor 6 is located close to the sensing element, and the temperature of the sensing element collected by the first temperature sensor 6 is the first collection temperature. The second temperature sensor 7 is located away from the water outlet 2, and the ambient temperature collected by the second temperature sensor 7 is the second collection temperature.

[0067] The first temperature sensor 6 and the second temperature sensor 7 are electrically connected to the first controller 9, respectively, and can feed back the first and second collected temperatures to the first controller 9.

[0068] The water outlet device also includes an operation display screen 8 located outside the body 10. The operation display screen 8 is electrically connected to the first controller 9 and has a water outlet button.

[0069] The working process of the water outlet device provided in this embodiment is as follows:

[0070] The user places a water container on the water receiving platform 3 and presses the water dispensing button on the operation display screen 8. The second controller then activates the water outlet 2 to dispense water. The first sensor transmits a first distance between the outlet and the liquid surface in the water container to the second controller. The second sensor transmits a second distance between the outlet and the highest point of the water container to the second controller. The second controller compares the absolute value of the difference between the first and second distances with a third preset distance. If the absolute value of the difference is greater than the third preset distance, the second controller continues to dispense water from the outlet 2. If the absolute value is less than or equal to the third preset distance, the second controller stops dispensing water from the outlet 2. Specifically, the user can set the third preset distance according to the actual application.

[0071] The first temperature sensor 6 transmits the first collected temperature from the sensing element to the first controller 9, and the second temperature sensor 7 transmits the second collected temperature to the first controller 9. The first controller 9 compares the absolute value of the difference between the first and second collected temperatures with a first preset temperature. The first preset temperature is the critical temperature at which steam condenses into water. If the absolute value of the difference between the first and second collected temperatures is greater than the first preset temperature, the heating function of the heat-transmitting plate and the heat dissipation component 5 are activated; if the absolute value of the difference between the first and second collected temperatures is less than the first preset temperature, the heating function of the heat-transmitting plate and the heat dissipation component 5 do not need to be activated.

[0072] Example 2

[0073] The similarities between this embodiment and Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that the water outlet device provided in this embodiment includes a hot water button, which is located on the outside of the body 10 and is electrically connected to the first controller 9.

[0074] The working process of the water outlet device provided in this embodiment is as follows:

[0075] The user places the water container on the water receiving platform 3. If only the water dispensing button is pressed, the heating function of the heating and light-transmitting plate and the heat dissipation component 5 will not be activated. The second controller controls the water outlet 2 to be in the water dispensing state. The first sensor transmits the first distance between itself and the liquid surface in the water container to the second controller. The second sensor transmits the second distance between itself and the highest point of the water container to the second controller. The second controller compares the absolute value of the difference between the first distance and the second distance with a third preset distance. If the absolute value of the difference between the first distance and the second distance is greater than the third preset distance, the second controller controls the water outlet 2 to continue dispensing water. If the absolute value of the difference between the first distance and the second distance is less than or equal to the third preset distance, the second controller controls the water outlet 2 to stop dispensing water.

[0076] If the user places the water container on the water receiving platform 3, presses the hot water button, the first controller 9 controls the heating function of the heating and light-transmitting plate and the heat dissipation component 5 to be turned on, and then presses the water outlet button, the second controller controls the water outlet 2 to be in the water outlet state until the absolute value of the difference between the first distance and the second distance is less than or equal to the third preset distance, the second controller controls the water outlet 2 to stop water outlet, and the first controller 9 controls the heating function of the heating and light-transmitting plate and the heat dissipation component 5 to be turned off.

[0077] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
