Description

[Detailed description of the invention] This invention uses the vibration of an ultrasonic vibrator to atomize water into fine particles, and by inhaling this mist into the nasal cavity and oral cavity, it moistens the mucous membranes, calms the dry state of the mucous membranes, and relieves inflammation. Concerning a liquid sprayer for soothing.

In a conventional liquid sprayer, as shown in FIG. 1, water is sucked up by a water absorbing body 22 and supplied to an ultrasonic vibrator 1 to be atomized, and the atomized water is discharged from a mist outlet 2. When you are there,
A part of this spray water adheres to the edge of the mist outlet 2 and condenses into water droplets, which then flow through the housing 3 (bottom surface of the mask) and are released from the housing 3 through the peephole 8 for checking the amount of water in the water tank 20. The drawback was that it spilled outside.

The present invention was made in view of the drawbacks of the conventional example described above, and its purpose is to bring the tip of the draining rib protruding from the edge of the mist outlet into contact with the water absorbing body. The water droplets that aggregate at the edge of the mist outlet are guided back to the water absorbing body,
Furthermore, it is an object of the present invention to provide a liquid sprayer that can transmit water through the surface of a water absorbing body and return it to a water supply tank, and prevent water droplets from spilling.

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 substantially round hole-shaped opening for the lower part of the device for mounting the ultrasonic transducer 1 thereon.

Immediately below the partition plate 6, there is built-in a printed wiring board 16 on which an oscillation circuit section 9 for vibrating the ultrasonic transducer 1 and a power switch 10 are mounted, and below the printed wiring board 16, a power supply section 1 is installed.
1 is provided.

The power supply section 11 has a dual power supply system, and can be supplied with a dry cell battery 12 to be used as a power source.A household AC power source can also be used as a power source via an external AC power adapter connected to a 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.The metal horn 15 has a tapered chamfered portion 31 on its outer periphery.

Reference numeral 20 denotes a water supply tank that is set on the partition plate 6 so as to be able to be taken in and out.A tank cap 39 is attached to the water absorption tank 20 in a watertight manner, and an inclined guide hole 40 is bored in the tank cap 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.

Furthermore, a peephole 8 for checking the amount of water is opened in the housing 3 so as to face the water absorption tank 20.

The water absorbing body 22 has a core material 33 made of a belt-like felt material such as a 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 leather resin molded product such as polypropylene resin, and the protection plates 34 on the front and back sides are held together. It is partially welded and integrated, and has a symmetrical shape along the longitudinal direction.

This welded portion 37 is provided with a mounting hole 35 bored therein.

Further, both ends of the core material 33 protrude slightly from both ends of the protection plate 34.

The bottom of the housing 3 is composed of a detachable bottom cover 17, and the upper part is composed of an accent ring 18 and a transparent, detachable bottomed cylindrical mask 25.

A through hole 26 and a mist ejection hole 2 are opened in the bottom walls of the accent ring 18 and the master holder 25, respectively, facing the installed dose lower, so that the ultrasonic vibration 1 is located facing the mist ejection hole 2. I have to.

There is a hook button 36 near the through hole 26 of the accent ring 18.
is drilled.

Then, the water absorbent body 22 is inserted into the guide hole 40, the lower end is immersed in water in the water absorption tank 20, and the upper end side attachment hole 35 is removably fitted into the hook button 36 to position the water absorbent body 22. 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 is projected further forward than the tip surface of the ultrasonic transducer 1.

Since the water absorbent body 22 is fitted with the hook button 36 in this manner, the water absorbent body 22 can be reliably brought into contact with the ultrasonic transducer 1 without floating or shifting.

Further, since the attachment hole 35 is provided in the welded portion 37 that is in close contact with the protection plate 34, the fitting force with the hook button 36 can be strengthened, making it difficult to remove the water absorbent body 22.

Furthermore, a draining rib 4 is provided in an arc shape to protrude from the lower edge of the mist outlet 2 toward the housing side, and when the mask 25 is attached, the tip of the draining rib 4 touches the surface of the water absorbent body 22. Even if the fitting between the mounting hole 35 and the hook button 36 deteriorates and loosens due to repeated attachment and detachment of the water absorbent body 22, the draining rib 4 presses the water absorbent body 22 and causes it to float or become misaligned, resulting in a worsening of the spray condition. So that you don't have to do anything.

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 the form of a thin film.

When waves occur on the vibrating surface due to vibration, the water film is torn off from the crest of the wave, and mist particles are generated and sprayed forward from the mist spouting hole 2.

At this time, a part of the spray water adheres to the edge of the mist jet hole 2, but when it aggregates and becomes water droplets, it flows along the draining rib 4 onto the water absorbent body 22, and further coats the surface of the protection plate 34. The water then flows downward and is collected into the water supply tank 20 through the guide hole 40, thereby preventing it from spilling out through the viewing window 8 or the like.

Since the present invention is constructed as described above, in short, the water droplets that adhere to the edge of the mist outlet and aggregate flow along the draining ribs to the water absorbing body, and then flow down along the water absorbing body to the water absorbing tank. The water is collected inside the housing, so it does not spill outside the housing, making it even more comfortable to use.Furthermore, the draining ribs touch and hold down the water absorbent body, ensuring that the water absorbent body does not lift up and receives ultrasonic vibrations. being brought into contact with a child,
This has the advantage that there is no risk of poor spraying.
