Referring to FIG. 1, a hand-held water dispenser 100 according to an embodiment of the present invention includes a cup body 110, a soft gel 120, a pressure sensor 130, a temperature sensor 140, and a processor (not shown).

[0035] The cup 110 is a hollow structure. The cup 110 includes a cup wall 112 and a bottom case 114. The cup wall 112 is a cylindrical structure in which a liquid can be contained. The cup wall 112 includes a crotch end and a closed end opposite the crotch end, and the bottom case 114 is disposed at the closed end.

[0036] The soft rubber 120 is disposed at the closed end, and the soft rubber 120 covers the closed end. Soft rubber 120 can be made of flexible material

[0037] The pressure sensor 130 is mounted in the bottom case 114 and connected to the soft rubber 120. The pressure sensor 130 is used to measure the pressure applied to the soft gel 120.

Specifically, in the embodiment, the soft rubber 120 includes a sheet-like main body 122 and a protrusion disposed on the sheet-like main body 122.

124, the protrusion 124 is connected to the pressure sensor 130. The projection 124 has a truncated cone shape and a certain surface area. The pressure measured by the pressure sensor 130 is the pressure exerted by the liquid above the projection 124 on the projection 124. Based on the known surface area of the projection 124 and the measured pressure data, the pressure experienced by the projection 124 can be measured, and the height of the liquid in the cup 110 can be roughly converted, and according to the height and the known cup 110. The cross-sectional area is converted into the volume of the liquid.

[0039] It can be understood that the protrusions 124 may also be other shape structures, and are not limited to a truncated cone shape.

[0040] The temperature sensor 140 is disposed on the inner side wall of the closed end. The processor is in communication with the pressure sensor 130 and the temperature sensor 140. The processor is configured to receive and process pressure data and temperature data measured by the pressure sensor 130 and the temperature sensor 140.

[0041] The temperature sensor 140 is used to measure the temperature of the soft gel 120. Due to the different temperatures of the liquid in the cup 110, the liquid The soft rubber 120 directly contacting the body will cause thermal expansion and contraction, thereby affecting the surface area of the portion in contact with the pressure sensor 130, affecting the measurement of the pressure, thereby affecting the measurement of the liquid volume. The temperature data of the soft gel 120 is measured by the temperature sensor 140, and the pressure data is compensated. The processor integrates the pressure data and the temperature data to accurately calculate the volume of the liquid in the cup 110.

[0042] The handheld water holding device 100 measures pressure data and temperature data of the soft rubber 120 in the cup body 110 by the pressure sensor 130 and the temperature sensor 140, and actually calculates the liquid volume inside the cup body 110, thereby calculating the user. The amount of drinking water satisfies the user's need to monitor the amount of drinking water in the smart water cup, which can promote users to drink more scientifically and regularly.

In addition, the above-mentioned hand-held water storage device 100 may further include a display screen (not shown), and the display screen is disposed outside the cup wall 12 12 . The processor is in communication with the display. After the processor calculates the volume of the liquid in the cup body 110, the liquid volume data can be transmitted to the display screen and displayed through the display screen, so that the user can easily know the current amount of drinking water.

In addition, in the embodiment, the hand water container 100 further includes a tray 150 disposed between the soft rubber 120 and the pressure sensor 130, and the protrusion 124 is connected to the pressure sensor 130 through the tray 150. The liquid in the cup 110 exerts pressure on the tray 150 through the projections 124, which conduct pressure to the pressure sensor 130.

[0045] The bottom case 114 has an annular structure, and the pressure sensor 130 and the tray 150 are housed in the bottom case 114. One side of the tray 150 is fixedly coupled to the pressure sensor 130, and the other side of the tray 150 is fixedly coupled to the bottom case 114 so that the tray 150 can be deformed under the pressure of the projection 124.

[0046] Specifically, the hand-held water dispenser 100 further includes a first threaded fastener 160 and a second threaded fastener 170.

The tray 150 is coupled to the pressure sensor 130 by a first threaded fastener 160. The bottom case 114 is further provided with a connecting plate 116, and the pressure sensor 130 and the connecting plate 116 are connected by a second threaded fastener 170.

[0047] Due to the majority of the pressure sensor 130 on the market, because of the structural size and the like, the measuring point is difficult to fully fit the protrusion 124 on the soft rubber 120, and the tray 150 is added to the hand-held water holding device 100. The pressure of the soft gel 120 can be well transferred to the pressure sensor 130 through the tray 150.

[0048] In addition, please refer to FIG. 2 together, and a method for monitoring the volume of the liquid in the handheld water holding device 100, further comprising the following steps: [0049] Step S210, providing the above-mentioned handheld water holding device.

[0050] The hand-held water holding appliance 100 described above is provided, and the cup 110 can hold a liquid therein. The liquid will exert pressure on the soft gel 120.

[0051] Step S220, the pressure data of the liquid applied to the soft body in the cup body is measured by the pressure sensor.

[0052] The pressure applied to the soft rubber 120 is measured by a pressure sensor 130 installed in the bottom case 114 to obtain pressure data. Specifically, the soft rubber 120 can apply pressure to the pressure sensor 130 through the protrusion 124 thereon, and the protrusion 124 has a truncated cone shape and has a certain surface area. The pressure measured by the pressure sensor 130 is the pressure exerted by the liquid above the projections 1 24 on the projections 124. Based on the known surface area of the projection 124 and the measured pressure data, the pressure experienced by the projection 124 can be measured, and the height of the liquid in the cup 110 can be roughly converted, and according to the height and the known cup 110. The cross-sectional area is converted into the volume of the liquid.

[0053] Step S230, measuring temperature data of the soft rubber by using a temperature sensor.

[0054] The temperature of the soft gel 120 is measured by a temperature sensor 140 mounted on the closed end to obtain temperature data. Specifically, the temperature sensor 140 is used to measure the temperature of the soft gel 120. Due to the different temperature of the liquid in the cup body 110, the soft rubber 120 directly contacting the liquid will cause thermal expansion and contraction, thereby affecting the surface area of the portion in contact with the pressure sensor 130, affecting the measurement of the pressure, thereby affecting the measurement of the liquid volume. The temperature data of the soft gel 120 is measured by the temperature sensor 140, and the pressure data is compensated.

[0055] Step S240, combining the pressure data and the temperature data, the volume of the liquid in the cup is obtained.

[0056] The processor can combine the measured pressure data and the temperature data to obtain the volume of the liquid in the cup body 110, so as to meet the user's need to monitor the drinking water volume of the smart water cup, and promote the user to drink more scientific and regular water. .
