In the embodiment of the utility model, a groove is formed on the side wall of the kettle by injection molding in the manufacturing process of the kettle.
The photosensor 310 is a device that converts an optical signal into an electrical signal based on the photoelectric effect. Specifically, the photosensor 310 further includes a circuit board 313. The light emitter 311 emits a light beam uninterruptedly, and the light beam is reflected to the receiver 312 by the reflection of the light reflection structure 320, so that the receiver 312 may receive the light signal emitted by the light emitter 311, and at this time, the circuit board 313 may output an electrical signal, and when the receiver 312 cannot receive the light signal emitted by the light emitter 311, the circuit board 313 may output another electrical signal, or may not output an electrical signal. The controller controls the opening and closing of the water valve according to the received different electric signals.
In the embodiment of the present invention, a height of the kettle 100 near the top thereof is set as a preset liquid level, and when the liquid level in the kettle reaches the preset liquid level, water is not required to be injected into the kettle, and the controller can control the water valve to close; when the liquid level in the kettle 100 does not reach the preset liquid level, water needs to be filled into the kettle, and the controller can control the water valve to be opened. The position of the photoelectric sensor 310 on the stand 200 corresponds to the height of the preset liquid level when the water jug 100 is placed on the stand 200. The light reflecting structure 320 is a portion of the sidewall of the kettle 100 and is disposed corresponding to the photo sensor 310. As shown in fig. 5, when the liquid level in the kettle 100 does not reach the predetermined liquid level, the first inclined surface 321, the transition plane 322 and the second inclined surface 323 of the light reflecting structure 320 form a light reflecting surface, a light path is established between the light emitter 311 and the receiver 312 through the light reflecting structure 320, the photoelectric sensor 310 outputs a first electrical signal, and the controller controls the water valve to open. During the water filling process, the liquid level in the kettle will continuously rise, and when the liquid level in the kettle 100 reaches the preset liquid level (as shown in fig. 6), because of the existence of the liquid in the kettle 100, the light path of the first inclined plane 321 cannot be transmitted to the transition plane 322, so that the light path transmission between the light emitter 311 and the receiver 312 is blocked, the photoelectric sensor outputs the second electric signal, and the controller controls the water valve to be closed.
In particular, the jug is made of a transparent plastic material, such as PS (polystyrene based plastics) or PP (polypropylene) and the like. The side wall of the kettle in the recess forms a first inclined plane 321, a transition plane 322 and a second inclined plane 323. When the liquid level in the kettle 100 does not reach the preset liquid level, the light emitted from the light emitter is vertically irradiated into the inner part of the side wall of the kettle and irradiated onto the first inclined surface 321; one side of the first inclined plane 321 is inside the sidewall of the kettle, and the other side is air, so that the first inclined plane 321 is an interface of two different media, and one side is an optically dense medium (kettle material) and the other side is an optically thinner medium (air), so that total reflection occurs at the first inclined plane 321. Thus, all incident light is reflected by the first inclined surface 321 and transmitted along the inside of the kettle sidewall parallel to the transition plane 322 until reaching the second inclined surface 323, and likewise, light is reflected from the second inclined surface 323 and, after passing vertically through the outer wall of the kettle, transmits an optical signal to the receiver 312. Thus, an optical path is established between the light emitter 311 and the receiver 312, the photoelectric sensor outputs a second electrical signal, and the controller controls the water valve to open. In the water injection in-process, the liquid level in the kettle 100 can constantly rise, when the liquid level in the kettle 100 reaches and predetermines the liquid level, one side of first inclined plane 321 is inside and the opposite side is water (the material of transparent kettle is very close with the refracting index of water), then can take place the refraction on first inclined plane 321 this moment, most light can directly pass first inclined plane 321 and shine to in the water, the reverberation of first inclined plane 321 can be very weak, finally, receiver 312 receives very weak light signal, correspondingly, photoelectric sensor outputs the second signal of telecommunication, then the controller can control the water valve and close.
In a similar manner, the photoelectric sensor is also able to detect whether the kettle is placed on the stand. That is, when the water bottle 100 is not placed on the stand 200, the light reflecting structure 320 is not present, and the light path transmission between the light emitter and the receiver 312 is not formed, the controller controls the water valve to be closed. When the water bottle 100 is placed on the stand 200 and the liquid level does not reach the preset liquid level, the photoelectric sensor detects the existence of the water bottle and the controller controls the water valve to open. Thereby ensuring that the water kettle 100 is not automatically filled when not in the stand 200.
The transition plane 322 is parallel to the side wall of the kettle 100, and the included angles between the first inclined plane 321 and the transition plane 322 and the second inclined plane 323 are both 45 °. In fact, the sidewall of the kettle forms a recess during injection molding, and the inner wall of the recess is formed by sequentially connecting the first inclined plane 321, the transition plane 322 and the second inclined plane 323. This can successfully establish the optical path transmission between the light emitter 311 and the receiver 312.
