Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] This utility model relates to a liquid level detection structure, including a liquid storage box 100 and a liquid level detection mechanism 200.

[0027] like Figure 1As shown, the interior of the liquid storage box 100 is divided into a liquid storage chamber 110 and a detection chamber 120 by a partition 101. The lower part of the liquid storage chamber 110 and the lower part of the detection chamber 120 are connected. Alternatively, a first connecting port 102 can be provided at or near the bottom of the partition 101, connecting the liquid storage chamber 110 and the detection chamber 120. A U-shaped connecting pipe structure is formed between the liquid storage chamber 110 and the detection chamber 120. A liquid level detection mechanism 200 is installed on the liquid storage box 100, and detects the liquid level in the detection chamber 120. The liquid level detection mechanism 200 can be connected to an external control system, and feeds back the detected liquid level signal to the external control system for user viewing. In actual use, the liquid storage chamber 110 is used to store foaming liquid. A liquid outlet 111 can be opened at the bottom of the storage chamber 110. The liquid in the storage chamber 110 is discharged outward through the liquid outlet 111, or an external foaming device can draw the liquid from the storage chamber 110 through a pump and a hose. When foaming liquid needs to be added, it is poured into the storage chamber 110, or it is supplied to the storage chamber 110 through an external liquid supply device. The foaming liquid flows into the detection chamber 120 through the first connecting port 102 in the storage chamber 110. According to the principle of communicating vessels, the liquid levels in the storage chamber 110 and the detection chamber 120 are consistent. During use, especially during the liquid addition process, foam will form on the surface of the foaming liquid in the storage chamber 110. Since the density of the foam is less than that of the foaming liquid, the foam will remain on the surface of the liquid in the storage chamber 110 and will not flow into the detection chamber 120. The foaming liquid flowing into the detection chamber 120 remains in a stable liquid state without foaming, so that the liquid level detection mechanism 200 is not affected by the foam and can accurately detect the liquid level height in the detection chamber 120, that is, can accurately detect the current liquid volume in the storage box 100.

[0028] The liquid level detection structure can be applied to various devices that require the use of foaming liquids such as hand sanitizer, shower gel, and shampoo. This utility model also relates to a foaming device, including the liquid level detection structure. The foaming device can foam foaming liquids such as hand sanitizer, shower gel, and shampoo for user use. It also relates to a smart toilet seat, which utilizes the aforementioned liquid level detection structure or foaming device. Furthermore, it relates to a toilet bowl, including the aforementioned liquid level detection structure, foaming device, or smart toilet seat. The foaming device extracts foaming liquid from the storage box 100 and foams it to form foam. The foam is then delivered to the toilet bowl cavity, where it can be used to clean the cavity or to form a foam layer on the water seal of the cavity.

[0029] In one embodiment, the liquid level detection mechanism 200 is a Time-of-Flight (TOF) sensor. A TOF sensor is a sensor based on signal time-of-flight distance measurement technology. The TOF sensor is mounted on top of the detection chamber 120, facing downwards to sense the liquid level height within the chamber. Because the foaming liquid surface in the detection chamber 120 does not bubble, the TOF sensor can accurately detect the current liquid level height.

[0030] In one embodiment, a second communication port 103 is provided between the upper part of the liquid storage chamber 110 and the upper part of the detection chamber 120. The second communication port 103 can be opened at the top of the partition 101. The second communication port 103 is provided with a waterproof and breathable membrane 300. Except for the first communication port 102 and the second communication port 103, the other positions of the detection chamber 120 can be sealed. The provision of the second communication port 103 can ensure that the gas pressure in the detection chamber 120 and the liquid storage chamber 110 remains equal. The gas in the detection chamber 120 and the liquid storage chamber 110 can communicate through the waterproof and breathable membrane 300. At the same time, the waterproof and breathable membrane 300 can isolate the foam in the liquid storage chamber 110, preventing the foam from flowing into the detection chamber 120 and thus not interfering with the detection of the liquid level detection mechanism 200.

[0031] like Figure 2 As shown, in one embodiment, the liquid level detection structure further includes a control module 400 and a display module 500. The control module 400 is one implementation of the aforementioned external control system. Both the liquid level detection mechanism 200 and the display module 500 can be electrically connected to the liquid level detection mechanism 200 via wires or other means. The liquid level detection mechanism 200 feeds back the currently detected liquid level height signal to the control module 400, and the control module 400 generates a relevant signal and sends it to the display module 500. The display module 500 can display the current foaming liquid storage amount or storage ratio in the storage box 100 in real time through digital display, progress bar, or text.

[0032] like Figure 2As shown, in one embodiment, the liquid level detection structure further includes a control module 400 and a buzzer 600. Both the liquid level detection mechanism 200 and the buzzer 600 can be electrically connected to the liquid level detection mechanism 200 via wires or other means. When the liquid level detection mechanism 200 detects that the liquid level in the detection chamber 120 has reached the highest preset threshold and / or the lowest preset threshold, the buzzer 600 sounds. For example, when a user adds foaming liquid to the storage chamber 110, the liquid level in the detection chamber 120 rises synchronously with the increase in the liquid level in the storage chamber 110. When the liquid level detection mechanism 200 detects that the liquid level in the detection chamber 120 has risen to the highest preset threshold, it feeds a signal back to the control module 400, which then controls the buzzer 600 to sound, reminding the user that the foaming liquid has been added and prompting the user to stop adding liquid. As the foaming liquid is used, the liquid level in the storage chamber 110 and the detection chamber 120 decreases synchronously. The liquid level detection mechanism 200 detects that the liquid level in the detection chamber 120 has dropped to the minimum preset threshold. The liquid level detection mechanism 200 feeds the signal back to the control module 400, and the control module 400 controls the buzzer 600 to sound, reminding the user to replenish the foaming liquid.

[0033] The liquid storage chamber 110 has a filling port 112 at its upper part, which can be located at or near the top of the liquid storage chamber 110. Users can add liquid to the liquid storage chamber 110 through the filling port 112. A cover 700 is installed on the filling port 112. The cover 700 can be opened or closed by flipping, screwing, or pulling the cover. A tactile switch 800 is also installed on the liquid storage box 100, which can be located on or near the filling port 112. The tactile switch 800 is electrically connected to the control module 400. When the cover 700 is closed on the filling port 112, the cover 700 presses the tactile switch 800, which sends a signal back to the control module 400, indicating that the filling port 112 is currently closed. When the cover 700 opens the liquid inlet 112, the cover 700 moves away from the tactile switch 800. The tactile switch 800 sends a signal to the control module 400, which then knows that the liquid inlet 112 is currently open. When the tactile switch 800 and the control module 400 detect that the cover 700 has been away from the cover 700 for more than a preset time, the control module 400 controls the buzzer 600 to sound, thus reminding the user to close the cover 700 on the liquid inlet 112.
