Description

[Detailed description of the invention] This invention uses the vibration of an ultrasonic vibrator to atomize water into fine particles, and inhales the atomized water into the nasal cavity and oral cavity to moisten the mucous membranes, soothe the dry state of the mucous membranes, and prevent inflammation. Concerning a liquid sprayer for soothing.

In the past, the amount of spray was set at a fixed amount in advance at the design or manufacturing stage, and the amount of spray needed for the inhalation effect or the amount of spray that matched the user's preference was adjusted for each device. It is inconvenient to use because it cannot be adjusted, and the level of satisfaction with the amount of spray varies depending on the user.

The present invention was developed in view of the drawbacks of the conventional examples mentioned above, and its purpose is to control the amount of spray with a simple structure that only adjusts the tightening force of the clamping means to which the water absorbent is attached. To provide a liquid atomizer that can be adjusted.

The present invention will be explained in detail below with reference to the accompanying drawings.

3 is a housing made of synthetic resin molding;
The upper part of the inside is separated from the street by a partition plate 6,
The partition plate 6 has a lower mounting capacity opening in the shape of a substantially round hole for mounting the ultrasonic transducer 1 thereon.

Immediately below the partition plate 6, there is built-in a printed wiring board 8 on which an oscillation circuit section 9 for vibrating the ultrasonic transducer 1 and a power supply switch 10 are mounted, and below the printed wiring board 8, a power supply section 1- is mounted.
1 is provided.

The power supply section 11 has a dual power supply system, and can be supplied with a dry cell battery 12 and used as a power source, or can also be used as a power source with a household AC power source via an external AC power adapter connected to the jack 13. It looks like this.

Reference numeral 1 denotes an ultrasonic vibrator consisting of an electrostrictive element 14 that generates vibrations and a metal horn 15 that magnifies the vibrations.A tapered chamfered portion 31 is formed on the outer periphery of the tip of the metal horn 15.

Reference numeral 20 denotes a water tank that can be freely inserted and removed on the partition plate 6. A tank camp 39 is attached to the water tank 20 in a watertight manner, and an inclined guide hole 40 is bored in the tank camp 39. This guide hole 40
The water absorbent body 22 is held so as to be gradually bent, thereby preventing an accident in which the water absorbent body 22 is locally extremely bent and the suction of water is stopped or lowered there.

The water absorbent body 22 has a core material 33 made of a belt-like felt body made of non-woven fabric made of acrylic resin, etc., and its front and back sides are sandwiched between belt-like protection plates 34 made of a synthetic resin molded product such as polypropylene resin. They are partially welded and integrated with each other, and have a symmetrical shape along the longitudinal direction, and mounting holes 35 are formed at both ends of the water absorbing body 220.

Further, both ends of the core material 33 protrude slightly from both ends of the protection plate 340.

The bottom of the housing 3 is composed of a detachable bottom cover 16, and the upper part is composed of an accent ring 17 and a transparent mask 25, which is detachable.

A bolt portion 4 is provided protruding from the accent ring 17 in the vicinity of the ultrasonic transducer 1, and the bolt portion 4 and the nand 5 constitute the clamping means 2.

That is, the attachment hole 35 of the water absorbing body 22 at the end on the ultrasonic transducer 1 side
Insert the bolt part 4 into the hole, screw the NAND 5 from above,
This allows the tightening force of the Nand 5 to be adjusted.

In this way, one end of the water absorbing body 22 is inserted into the guide hole 40, one end is immersed in water in the water absorption tank 20, the other end side attachment hole 35 is passed through the bolt part 4, and the Nand 5 is tightened from above to absorb water. The body 22 is positioned, and the tip of the core material 33 is brought into oblique contact with the chamfered portion 31 on the side surface of the tip of the ultrasonic transducer 1, so that the front surface of the core material 33 protrudes forward beyond the tip surface of the ultrasonic transducer 1. It's a shame.

When the power switch 10 is turned on, a high frequency voltage generated by the oscillation circuit section 9 and having a frequency substantially equal to the mechanical resonance frequency of the metal horn 15 is applied to the electrostrictive element 14.

The ultrasonic vibrations generated by the electrostrictive element 14 are transmitted through the metal horn 1.
5, and the spray surface at the tip of the metal horn 15 is caused to vibrate greatly due to the amplitude enlarging action of the metal horn 15.

On the other hand, the core material 33 of the water absorbing body 22 sucks up the water in the water absorption tank 20 by capillary action, and supplies the water to the vibrating surface of the tip of the metal horn 15 in a thin film form.

When vibrations cause waves on the vibrating surface, the water film is torn off from the wave crest, generating mist particles that are sprayed forward.

At this time, the amount of spray is determined by the amount of water supplied to the water absorbing body 22 as long as it is within the spraying capacity of the ultrasonic vibrator 1.
By tightening the NAND 5 and compressing the core material 33 of the water absorbing body 22 thinly, the amount of water supplied can be reduced and the amount of spray can be reduced. By loosening the NAND 5 and inflating the core material 33, the amount of water supplied can be increased and the amount of spray can be reduced. can be easily adjusted by simply turning the Nando 5.

Since the present invention is constructed as described above, it is possible to attach and position the water absorbent body to the housing using the clamping means, and the water absorbent body can be reliably brought into contact with the ultrasonic transducer, and the clamping means can be tightened. The attachment allows you to adjust the amount of water supplied to the ultrasonic vibrator of the water absorber by simply tightening or loosening it by adjusting the force, and the user also has the advantage of being able to adjust the amount of spray with a simple structure. be.
