[0029] The water level detection equipment provided by this utility model is described below with reference to specific embodiments.

[0030] Figures 1 to 5A schematic diagram of a water level detection device provided in an embodiment of the present invention is shown. For ease of explanation, only the parts related to the embodiment of the present invention are shown.

[0031] In this embodiment of the utility model, the water level detection device may include at least a water volume sensing plate 1, a pressure sensor 2, a support plate 3, a push rod 4, a container limiting plate 5, a control device, a water outlet device 7, a limiting groove 8, a drive device, and a power supply.

[0032] Specifically, the water volume sensing plate 1 is used to detect the amount of water overflowing from the container 6; the pressure sensor 2 is used to detect the pressure data of the water overflowing from the container 6; the support plate 3 is used to place the container 6; the push rod 4 is used to push the support plate 3 when the container 6 is filled with water, causing the support plate 3 and the container 6 to tilt, and to retract after the container 6 is filled with water, causing the support plate 3 and the container 6 to become horizontal; the control device is used to acquire the water volume data detected by the water volume sensing plate 1 and the pressure data detected by the pressure sensor 2 in real time, and to determine whether the container 6 is full of water based on the water volume data and the pressure data; the water outlet device 7 is used to stop discharging water after the container 6 is full of water; the limiting groove 8 is used to limit the height of the push rod 4; the driving device is used to drive the push rod 4 to rise when the container 6 is filled with water, and to drive the push rod 4 to retract after the container 6 is full of water; the power supply is used to supply power to the water volume sensing plate 1, the pressure sensor 2, the control device, and the water outlet device 7.

[0033] Specifically, such as Figure 1 As shown, Figure 1 This is a schematic diagram of a water level detection device for a container in an inclined state, provided by an embodiment of the present invention. The water volume sensing plate 1 and the pressure sensor 2 are disposed on one side of the container limiting plate 5, and the water volume sensing plate 1 and the pressure sensor 2 are horizontally overlapped. The support plate 3 and the push rod 4 are disposed on the other side of the container limiting plate 5, and the support plate 3 abuts against the push rod 4. Under the push of the push rod 4, the support plate 3 forms an inclined surface. When the container 6 is placed on the support plate 3 and limited by the container limiting plate 5, the liquid overflowing from the container 6 passes through the water volume sensing plate 1.

[0034] also, Figure 2 and Figure 4 This diagram illustrates the structure of a water level detection device for a water purifier, as provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of a water purifier with the container tilted. Figure 4 A schematic diagram of a water purifier with the container in a horizontal position; Figure 3 This diagram illustrates the structure of a water level detection device for a container in a horizontal state, according to Embodiment 1 of the present invention. Figure 5 The diagram shows a cross-sectional schematic of a water level detection device for a water purifier provided in Embodiment 1 of this utility model.

[0035] Specifically, the push rod 4 is disposed in the limiting groove 8. When the push rod 4 is completely in the limiting groove 8, the support plate 3 is parallel to the horizontal plane, and the container 6 is in a horizontal state.

[0036] Specifically, the control device is connected to the water volume sensing plate 1, the pressure sensor 2, and the water outlet device 7, respectively.

[0037] Specifically, the pressure sensor 2 is located on the side of the water flow sensing plate 1 away from the water outlet device 7.

[0038] Specifically, the drive device is connected to the push rod 4.

[0039] Specifically, the support plate 3 is fixedly connected to or hinged to the container limiting plate 5.

[0040] Specifically, the power supply is connected to the water volume sensing plate 1, the pressure sensor 2, the control device, and the water outlet device 7, respectively.

[0041] Specifically, the water volume sensing plate 1 detects water volume data based on changes in the total amount of light received.

[0042] Specifically, the control device may be a microprocessor or controller with data storage and computing capabilities.

[0043] Specifically, since there may be residual liquid on the water level sensor 1 before water overflows from the container 6, judging whether the container 6 is full of water based solely on the water level data detected by the water level sensor 1 may lead to misjudgment. Therefore, judging whether the container 6 is full of water by combining the data changes of the water level sensor 1 and the pressure sensor 2 can improve the accuracy of judging the water level of the container.

[0044] Specifically, the water level detection device can be applied to a water purifier. Before the container 6, which is to be filled with water, is placed on the support plate 3, the push rod 4 is completely within the limiting groove 8, and the support plate 3 is parallel to the horizontal plane. After the user places the container 6 on the support plate 3, the driving device drives the push rod 4 to rise. Under the push of the push rod 4, the support plate 3 and the container 6 become tilted, and the container 6 is limited by the container limiting plate 5. During the water dispensing process of the water dispensing device 7, the amount of water in the container 6 gradually increases. When water overflows from the container 6, the overflowing water will pass through the water volume sensing plate 1 located on the side of the container limiting plate 5 away from the push rod 4. The water volume sensing plate 1 detects the amount of water... The data and pressure data detected by the pressure sensor 2, which is horizontally overlapped with the water volume sensing plate 1, will change. The control device acquires the water volume data detected by the water volume sensing plate 1 and the pressure data detected by the pressure sensor 2 in real time. When both the water volume data and the pressure data change, it is determined that the container 6 is full of water. The control device sends a stop water dispensing signal to the water dispensing device 7. The water dispensing device 7 stops dispensing water, and the drive device drives the push rod 4 to retract, so that the support plate 3 and the container 6 become horizontal, making it convenient for the user to pick up the container 6. At this time, the container 6 still has some remaining space, which can prevent liquid from spilling or scalding the user when picking it up. In this embodiment of the utility model, when the container is filled with water, the push rod makes the container tilt. When water overflows from the container, the data changes of the water volume sensing plate and the pressure sensor can determine that the container is full of water. The water outlet is then automatically stopped, so that it can accurately determine whether the container is full of water. This eliminates the need for users to wait for the container to fill up for a long time or manually stop the water dispensing, thus improving the user experience.

[0045] In another embodiment of the present invention, in order to remind the user when the container 6 is full of water, the water level detection device further includes a water level information output device, which is connected to the control device.

[0046] Specifically, the water level information output device may include a water level information display module;

[0047] Specifically, the water level information display module can display a "water cup is full" message after the container 6 is filled with water;

[0048] Specifically, the water level detection device can be applied to a water purifier. Before the container 6 to be filled with water is placed on the support plate 3, the push rod 4 is completely within the limiting groove 8, and the support plate 3 is parallel to the horizontal plane. After the user places the container 6 on the support plate 3, the driving device drives the push rod 4 to rise. Under the push of the push rod 4, the support plate 3 and the container 6 become tilted, and the container 6 is limited by the container limiting plate 5. During the water dispensing process of the water dispensing device 7, the water volume in the container 6 gradually increases. When water overflows from the container 6, the overflowing water will pass through the water volume sensing plate 1 located on the side of the container limiting plate 5 away from the push rod 4. The water volume data detected by the water volume sensing plate 1 and the pressure data detected by the pressure sensor 2, which is horizontally overlapped with the water volume sensing plate 1, will change, and the control... The control device acquires water volume data detected by the water volume sensor 1 and pressure data detected by the pressure sensor 2 in real time. When both water volume and pressure data change, it determines that the container 6 is full of water. The control device sends a stop water dispensing signal to the water dispensing device 7, which stops dispensing water. The drive device drives the push rod 4 to retract, making the support plate 3 and the container 6 horizontal, making it easier for the user to pick up the container 6. At this time, the container 6 still has some remaining space, which can prevent liquid from spilling or scalding the user when picking it up. In addition, the control device sends a first prompt signal to the water level information display module in the water level information output device. The water level information display module displays a "water cup is full" prompt message to remind the user after the container 6 is full of water. In this embodiment of the invention, when the container is filled with water, a push rod tilts the container. When water overflows from the container, the changes in data from the water level sensor and pressure sensor determine that the container is full. The system then automatically stops the water flow from the outlet and alerts the user that the container is full. This allows for accurate judgment of whether the container is full, eliminating the need for users to wait for the container to fill or manually stop the water flow, thus improving the user experience.

[0049] In another embodiment of the present invention, in order to remind the user when the container 6 is full of water, the water level detection device further includes a water level information output device, which is connected to the control device.

[0050] Specifically, the water level information output device may include an audio output module;

[0051] Specifically, the audio output module can output a prompt audio after the container 6 is filled with water;

[0052] Specifically, the water level detection device can be applied to a water purifier. Before the container 6, which is to be filled with water, is placed on the support plate 3, the push rod 4 is completely within the limiting groove 8, and the support plate 3 is parallel to the horizontal plane. After the user places the container 6 on the support plate 3, the driving device drives the push rod 4 to rise. Under the push of the push rod 4, the support plate 3 and the container 6 become tilted, and the container 6 is limited by the container limiting plate 5. During the water dispensing process of the water dispensing device 7, the amount of water in the container 6 gradually increases. When water overflows from the container 6, the overflowing water will pass through the water volume sensing plate 1 located on the side of the container limiting plate 5 away from the push rod 4. The water volume sensing plate 1 detects the water volume data, and the pressure data detected by the pressure sensor 2, which is horizontally overlapped with the water volume sensing plate 1, is also detected. The flow rate will change. The control device acquires the water volume data detected by the water volume sensor 1 and the pressure data detected by the pressure sensor 2 in real time. When both the water volume data and the pressure data change, it is determined that the container 6 is full of water. The control device sends a stop water dispensing signal to the water dispensing device 7. The water dispensing device 7 stops dispensing water, and the drive device drives the push rod 4 to retract, so that the support plate 3 and the container 6 become horizontal, making it convenient for the user to pick up the container 6. At this time, the container 6 still has some remaining space, which can prevent the liquid from spilling or scalding the user when picking it up. In addition, the control device sends a second prompt signal to the audio output module in the water level information output device. The audio output module outputs a prompt audio to remind the user after the container 6 is full of water. In this embodiment of the invention, when the container is filled with water, a push rod tilts the container. When water overflows from the container, the changes in data from the water level sensor and pressure sensor determine that the container is full. The system then automatically stops the water flow from the outlet and alerts the user that the container is full. This allows for accurate judgment of whether the container is full, eliminating the need for users to wait for the container to fill or manually stop the water flow, thus improving the user experience.

[0053] In another embodiment of the present invention, in order to remind the user when the container 6 is full of water, the water level detection device further includes a water level information output device, which is connected to the control device.

[0054] Specifically, the water level information output device may include a water level information display module and an audio output module;

[0055] Specifically, the water level information display module can display a "water cup is full" message after the container 6 is filled with water;

[0056] Specifically, the audio output module can output a prompt audio after the container 6 is filled with water;

[0057] Specifically, the water level detection device can be applied to a water purifier. Before the container 6 to be filled with water is placed on the support plate 3, the push rod 4 is completely within the limiting groove 8, and the support plate 3 is parallel to the horizontal plane. After the user places the container 6 on the support plate 3, the driving device drives the push rod 4 to rise.

When water overflows from the container 6, the overflowing water will pass through the water volume sensing plate 1 located on the side of the container limiting plate 5 away from the push rod 4. The water volume data detected by the water volume sensing plate 1 and the pressure data detected by the pressure sensor 2, which is horizontally overlapped with the water volume sensing plate 1, will change. The control device acquires the water volume sensing data in real time. The control device detects the water volume data from plate 1 and the pressure data from pressure sensor 2. When both the water volume data and pressure data change, it is determined that container 6 is full of water. The control device sends a stop water dispensing signal to the water dispensing device 7, which stops dispensing water. The drive device drives the push rod 4 to retract, making the support plate 3 and container 6 horizontal, making it easier for the user to pick up container 6. At this time, container 6 still has some remaining space, which can prevent liquid from spilling or scalding the user when picking it up. In addition, the control device sends a third prompt signal to the water level information display module and the audio output module in the water level information output device. The water level information display module displays the prompt message "Water cup is full" to the user, and the audio output module outputs a prompt audio to remind the user after container 6 is full of water.
