A plurality of elastic plates 41 abut against each other to seal the water outlet 3, and the elastic plates 41 elastically deform when subjected to an external force, so that the water control device 4 adjusts the water output according to the force received.

The elastic plate 41 is made of elastic materials, such as plastic, silica gel, soft rubber, etc., and the Shore hardness is between 20-40. Through the abutment between a plurality of slightly arched elastic plates 41, the It can bear the set pressure without water leakage, so as to achieve the same effect as the spring structure, but the structure is far simpler than the prior art.

In order to facilitate more effective discharge of water from the box body 1 through the water outlet 3, the water control device 4 can be connected to an external water pump (not shown in the figure), so that the water box has a wider application range.

When the pressure is insufficient to force the elastic plate 41 to undergo elastic deformation capable of allowing water to pass, the water cannot be discharged from the water control device 4. As the amount of water in the box body 1 increases, the pressure on the elastic plate 41 also gradually increases, and the elastic plate 41 undergoes elastic deformation, so that the speed of the water discharged through the water control device 4 changes from small to large. According to actual conditions, an external water pump can be used to further increase the force received by the elastic plate 41, thereby accelerating the drainage speed.

When those skilled in the art face the drainage structure of the water tank used in the nursing machine, since most of the prior art applications are spring ejection structures, the main design principle is to realize it through the elastic deformation of the spring after the force is applied. The drainage control of the water outlet 3, therefore, even if those skilled in the art want to improve the existing spring ejection structure, in order to overcome the problems that the spring is easy to rust, the spring is easy to fail and cause water leakage, most of the problems in the structure are It also focuses on the transformation of the spring ejection structure itself and the selection of spring materials.

For example, those skilled in the art will focus on the problem of long-term contact with liquid, which is the key component of the spring ejection structure, and the spring is prone to rust. Usually, the sealing between the movable connecting plate provided on the top of the spring and the pipe is strengthened to avoid water seepage. Leaking below the movable connecting plate and contacting the spring, or selecting suitable materials to directly improve the anti-rust ability of the spring.

If a structure like a piston is used as the movable connecting plate to achieve the effect of strengthening the sealing of the pipeline, but because the water inside the box 1 flows to the water outlet 3, there is not much water at the water outlet 3, which produces The pressure is also limited. The water pressure in the water outlet 3 is usually difficult to overcome the friction between the movable connecting plate of the piston and the like and the pipe. At this time, the movable connecting plate will also be supported by the spring, making it even more difficult. The water is effectively discharged through the water outlet 3.

To directly improve the anti-rust ability of the spring, for example, install a water-proof structure such as a tarpaulin around the spring, or use an anti-rust spring. However, the tarp is prone to breakage with the extension or diastolic movement of the spring for a long time. The use of anti-rust springs will rust in some environments.

Even if a person skilled in the art adopts the above method to improve the existing spring ejection structure, it is difficult to avoid the application with the spring as the core, and there is still the problem of complex overall structure, and it is difficult to overcome the problem of the spring itself that is prone to jams. Problems such as hysteresis, rebound and other failures, and the spring cannot be reset in time, which cause water leakage in the spring ejection structure. In addition, when the pressure generated by the amount of water in the box body 1 is insufficient to allow the water to be smoothly discharged from the water outlet 3, it is difficult to adjust conveniently, quickly and effectively due to the limitation of the structure of the spring ejection structure. Moreover, when the spring ejection structure is adopted, the drainage method is to drain around the pipe, and a special water receiving structure is required.

In the present invention, the drainage cover 6 can be installed on the water outlet 3 by means of threads or the like, and the water control device 4 can be installed on the water outlet 3 through the connecting piece 5, which is easy to disassemble. Although the spring ejection structure in the prior art can also be detachably installed on the water outlet 3, when the spring fails and needs to be replaced, due to the structural characteristics of the spring ejection structure, one end of the spring is fixedly installed on the structure For the pipeline, only the overall spring ejection structure can be removed for processing. Although it is also necessary to disassemble the overall structure in the present invention, the connecting piece 5 and the water control device 4 can be easily disassembled, and only the defective parts need to be replaced.

The innovation of the present invention is also that the inventor of the present invention directly abandoned the application of the spring, and replaced the spring ejection structure with a structure in which the elastic plate 41 arched or bounced and abutted each other, using non-metallic materials. The elastic plate 41 is made to realize the sealing of the water outlet 3, thereby overcoming various problems existing in the spring ejection structure. The discharged water can be directly connected to the corresponding pipe for discharge, and it is convenient to install an external drive when necessary. Devices such as water pumps to enhance the drainage effect, these are difficult to think of those skilled in the art when trying to improve the existing spring ejection structure, thus providing a new application in the drainage application of the water box of the nursing machine. The direction of solving the problem.

In summary, the present invention solves the problem that the spring ejection structure is provided at the water outlet of the water box in the prior art. The structure is relatively complex and easy to malfunction and cause water leakage. The spring is mostly made of metal and is in contact with liquid for a long time. The problem of rust.

Moreover, the structure is simple and the application is convenient. The elastic plate 41 of the water control device 4 protrudes toward the inner direction of the box body 1, and the sealing effect on the water outlet 3 is better. The water control device 4 is installed on the connecting piece 5, and the connecting piece 5 is installed in the annular groove 61 provided in the drain cover 6 to realize the stable installation of the water control device 4 on the drain cover 6. Moreover, the water control device 4 is easily taken out of the drain cover 6 under the driving of the connecting piece 5, and only the connecting piece 5 is separated from the annular groove 61. The drainage cover 6 is installed on the water outlet 3, which is convenient for disassembly and installation, and can be used to transform the existing water tank. A return port 8 is provided, and the condensed water obtained by the nursing machine after condensing the water vapor of the clothes is sent into the box body 1, which is convenient for centralized processing. A water level measuring device 7 is provided to measure the water level in the box 1 so that the operator can grasp the water level in the box 1.
