Description

Ultrasonic Bathtub Fogger

technical field

The invention relates to the field of electronic sanitary equipment, in particular to a bathtub mist maker.

Background technique

During the bathing process, it is generally desired to form more water vapor above the bathtub, so that the human skin is bathed in warm water vapor, which is not only comfortable but also warm. However, the water vapor formed by the natural evaporation of hot water in the bathtub is very limited, which is difficult to meet the demand. For this reason, there are currently some stand-alone or all-in-one bathtub foggers that utilize ultrasonic transducers to convert water into water vapor. This kind of system has a complex structure. Firstly, it is necessary to use a guide tube to guide the hot water in the bathtub to the working area of the ultrasonic transducer, and then guide the water vapor to the steam outlet on the side of the bathtub through the air channel. This not only greatly increases the cost of the bathtub, but also the dirt in the bathtub is very easy to enter and deposit in the guide pipe or the steam outlet, so that the water vapor discharged from the steam outlet is polluted, and the temperature of the water vapor is greatly reduced ; Or blockage of the guide tube, resulting in failure.

Contents of the invention

In view of the above problems, the object of the present invention is to provide an ultrasonic bathtub mist maker, which can independently float on the water surface in the bathtub and directly form water vapor on the water surface, which not only costs less, but also can Form clean and higher temperature water vapor.

The technical solution adopted by the present invention to solve the technical problem is: the ultrasonic bathtub fogger includes a base body, and above the base body is provided with an ultrasonic atomizing sheet with the working surface facing upwards; the inside of the base body is sealed with a A circuit board and a battery module powered by the atomizing sheet; an annular neck and an annular cavity are sequentially arranged above the ultrasonic atomizing sheet; water holes are evenly distributed on the surrounding wall of the annular neck, and the hollow inner cavity of the annular cavity constitutes buoyancy body; the center of gravity of the mist maker is at the lower part of the base body, and the weight of the mist maker satisfies the following characteristics: when the mist maker is placed in water, the horizontal plane is above the annular neck, and the lower on the upper surface of the annular cavity.

Preferably, the base body is hemispherical, and the ultrasonic atomizing sheet is embedded in the upper surface of the base body.

Preferably, the battery module is a button battery or a 23A/12V dry battery with a small volume.

As a preference, a cold storage chamber filled with cold storage agent is provided in the base body, and the lower bottom surface of the cold storage chamber is in thermal contact with the cold surface of the thermoelectric generation sheet in the base body; the lower part of the base body is composed of a metal block, and the metal block The block is in thermal contact with the hot surface of the thermoelectric sheet; the thermoelectric sheet constitutes the battery module, and the generating electrodes of the thermoelectric sheet are coupled to the circuit board.

The beneficial effect of the present invention is that: when the ultrasonic bathtub fogger is in use, it can float on the water surface only by being placed in the bathtub. Since the ultrasonic atomizing sheet is in a relatively shallow position below the water surface, it can A large amount of mist is generated on the surface of the bathtub; after multiple mist generators are thrown into the bathtub, a large amount of hot steam can be formed above the bathtub. High and clean.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention is further described:

In the first embodiment shown in FIG. 1 , the ultrasonic bathtub mist maker includes a hemispherical base 1 , and above the base 1 is provided an ultrasonic atomizing sheet 2 with a horizontally upward working surface. The ultrasonic atomizing sheet 2 Surrounded by the base body 1, the ultrasonic atomizing sheet 2 is embedded; the base body 1 is sealed with a circuit board 3 and a battery module 4 for supplying power to the ultrasonic atomizing sheet 2; the circuit board 3 will The direct current provided by the battery module 4 is converted into a high-frequency alternating current to drive the ultrasonic atomizing sheet 2 to vibrate at a high frequency at a frequency of 0.6MHz~2.4MHz; the upper part of the ultrasonic atomizing sheet 2 is sequentially provided with an annular neck 5, an annular Cavity 6; water holes 50 are evenly distributed on the peripheral wall of the annular neck 5, so that the water body outside the annular neck 5 can flow into the annular neck 5 through the water holes 50, and the hollow inner cavity of the annular cavity 6 constitutes a buoyancy body ; The center of gravity of the mist maker is located directly below the base body 1. For this reason, a counterweight can be provided directly below the base body 1; and the weight of the mist maker satisfies the following characteristics: the mist maker is placed on When in water, the water level is above the annular neck 5 and lower than the upper surface of the annular chamber 6 .

In the aforementioned ultrasonic bathtub fogger, the battery module 4 is a button battery or a 23A/12V dry battery, and has a small volume.

When the above-mentioned ultrasonic bathtub fogger is in use, it only needs to be placed in the bathtub to float on the water surface. Since the ultrasonic atomizing sheet 2 is in a relatively shallow position below the water surface, it can directly generate a large amount of mist on the water surface; After multiple mist generators are thrown into the bathtub, a large amount of hot steam can be formed above the bathtub. The mist generator is small and simple in structure, low in cost, and the hot steam is directly generated on the water surface, so the temperature is higher and cleaner.

For the second embodiment shown in Figure 2, the difference from the first embodiment is that the base body 1 is provided with a cold storage chamber 7 filled with cold storage agent, and the lower bottom surface of the cold storage chamber 7 is connected to the thermoelectric power generation sheet 8 in the base body. The cold surface of the base body 1 is in heat conduction contact; the lower part of the base body 1 is composed of a metal block 9, and the metal block 9 is directly used as a counterweight of the base body 1; the metal block 9 is in heat conduction contact with the hot surface of the thermoelectric sheet 8; The thermoelectric generating sheet 8 constitutes the battery module, and the generating electrode of the thermoelectric generating sheet 8 is coupled to the circuit board 3; in the second embodiment, the thermoelectric generating sheet 8 directly contacts the hot water in the bathtub through the metal block , so the hot surface of the thermoelectric generation sheet 8 is basically the same temperature as the hot water in the bathtub, and the cold surface of the thermoelectric generation sheet 8 is in contact with the cold storage chamber 7, so that the temperature difference between the cold and hot surfaces of the thermoelectric generation sheet 8 is relatively large, which can form Larger current, to impel the ultrasonic atomizing sheet 2 to vibrate. Wherein, for the cold storage chamber 7, in order to store more cooling capacity, the mist maker can be placed in a refrigerator to refrigerate when the mist maker is not working.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications and equivalent replacements made within the spirit and principles of the present invention should be included within the protection scope of the present invention .
