Description

Liquid discharge machine

The present invention relates to a discharge machine, and more particularly to a liquid discharge machine.

A liquid discharge machine suitable for storing and discharging a liquid, the liquid discharge machine comprising a hollow outer casing unit, a liquid storage tank disposed in the outer casing unit, a water storage tank defined by the liquid storage tank and suitable for a liquid storage space for accommodating the liquid, a discharge module disposed in the outer casing unit and connected to the liquid storage tank, an input module disposed outside the outer casing unit, and an electrical connection disposed in the outer casing unit The input module and the control module of the discharge module, and a capacitance level gauge disposed in the housing unit and electrically connected to the control module.

The liquid storage tank includes a detection hole adjacent to the bottom of the liquid storage tank and extending through the liquid storage tank and communicating with the liquid storage space. The capacitance level gauge includes a power receiving portion located outside the liquid storage tank and electrically connected to the control module, and a detecting portion connecting the power receiving portion and passing through the detecting hole to contact the liquid in the liquid storage space .

In use, the control module can control the amount of liquid corresponding to the discharging of the discharging module according to the instruction input by the user in the input module, and can also determine the capacitance data measured according to the capacitance liquid level. The height of the liquid remaining in the reservoir to remind the user to add liquid at the right time.

However, since the capacitance level gauge is directly in contact with the liquid for measurement, there is a concern that the hygienic condition is poor, and if the detection hole is poorly sealed, there is a disadvantage that the liquid leaks. In addition, the capacitance level gauge is generally suitable for detecting a liquid having a small consistency, and if it is used for detecting a liquid having a large viscosity (for example, fructose), it is easy to have a problem of poor accuracy.

Another liquid discharge machine of the prior art has the same main structure as the former liquid discharge machine, but the other liquid discharge device has a pressure sensor disposed under the liquid storage tank, and according to the liquid storage tank The change in gravity imparted by the pressure sensor calculates the weight of the remaining liquid in the reservoir.

The other liquid discharge machine can improve the problem of poor hygiene and poor accuracy of the existing liquid discharge machine, however, limited by the detection principle of the pressure sensor, the other liquid discharge machine The liquid storage tank needs to be disposed up and down on the pressure sensor, so that during the transportation process, the liquid storage bucket may be repeatedly displaced up and down to hit the pressure sensor due to the bumpiness of the road surface during transportation, and the pressure is also caused by the pressure. The sensor is disposed in the outer casing unit and located under the liquid storage tank, so that it is not easy to be coated with other packaging materials to mitigate the impact, so the liquid storage tank and the pressure sensor are easily damaged.

Therefore, the object of the present invention is to provide a liquid discharge machine which is hygienic, has good accuracy, and is not easily damaged during transportation.

Thus, the novel liquid discharge machine is suitable for storing and discharging liquid, and the liquid discharge machine comprises a body device.

The body device comprises a shell unit, a liquid storage tank, a discharging module, an input module, a weighing module, and a control module.

The shell unit has a casing, a liquid inlet formed in the casing, and a liquid outlet formed on the casing and spaced apart from the inlet. The housing has a bottom wall, a surrounding wall extending upwardly from the periphery of the bottom wall, and a top wall connecting the top periphery of the surrounding wall.

The discharge module is disposed in the accommodating space and communicates with the second opening and the liquid outlet, and can be controlled to transfer a predetermined amount of liquid from the second opening to the liquid outlet. The input module is disposed outside the housing and can be operated to input an instruction.

The weighing module has a plurality of weight sensors, each weight sensor having a bonding area that fits the bottom wall, and a top abutting area opposite the bonding area and located below the bottom wall.

The control module is disposed in the accommodating space and electrically connected to the discharging module, the input module, and the weighing module. The control module can receive the command of the input module, and control the discharging module to transfer a predetermined amount of liquid from the second opening to the liquid outlet to discharge the outside of the body device.

When the body device is placed on a surface, the control module can determine whether the weight of the liquid in the liquid storage tank is less than a predetermined value according to the weight of the body device measured by the weight sensors.

The utility model has the following advantages: when the weighing device is arranged to place the body device on a surface, the control module can determine the weight of the body device measured by the weight sensors. Whether the weight of the liquid in the liquid storage tank is less than a predetermined value. In addition, since the abutment zones are located under the bottom wall, it is easy to cover the abutment zones with the impact-reducing packaging material during transportation to avoid damage to the abutment zones.
