The nozzle shaft 34 of the ultrasonic oscillator 14 is firmly fixed to the lower part of the storage tank 16 while the nozzle nut 40 is supported together.

  As shown in FIG. 4, the storage tank 16 is a container for storing a predetermined amount of liquid (such as water or other lotion) inside, and is used for installing the vent opening / closing adjustment unit 26 at the top. A first communication part 16a is formed, and a second communication part 16b for installing the ultrasonic oscillator 14 is formed in the lower part. In the drawing, an unexplained reference numeral 16 ′ is a member that is coupled to the storage tank 16 and seals the internal space, and corresponds to a cover.

  The second communication portion 16 b supplies the liquid stored in the storage tank 16 to the outside through the nozzle shaft 34 in a state where the nozzle shaft 34 of the ultrasonic oscillator 14 is firmly fixed via the inner packing 58. The liquid that functions and is provided to the outside through the nozzle shaft 34 is atomized by the ultrasonic vibration generated by the ultrasonic oscillator 14 and jetted to the outside. At this time, the liquid sprayed to the outside is further atomized through the mesh 50 located at one end of the nozzle shaft 34.

  The first communication part 16 a serves to allow external air to flow into the storage tank 16 by installing the vent opening / closing adjustment part 26 in the upper part of the storage tank 16. That is, when the vent opening / closing adjustment unit 26 is opened, external air is introduced into the storage tank 16 through the first communication part 16a of the storage tank 16 so that atmospheric pressure acts. The internal storage liquid can be continuously supplied smoothly to the nozzle shaft 34 of the ultrasonic oscillator 14 through the second communication portion 16b.

  The circuit board 18 serves to supply the power of the battery 20 to the ultrasonic oscillator 14 by operating the injection switch 28. More specifically, power is supplied to the piezo element 36 through the ring terminal 38. At this time, the circuit board 18 can variably adjust the energization time to the ultrasonic oscillator 14 when the injection switch 28 is operated once. On the other hand, by adopting an on / off type as the injection switch 28, the energization time from the circuit board 18 to the ultrasonic oscillator 14 can be interlocked by switching the injection switch 28. For this purpose, the circuit board 18 includes a first connector 18a for electrical connection with the lead wire 44 of the ultrasonic oscillator 14, a second connector 18b for electrical connection with the battery 20, and the A charging port 18c exposed to the outside by opening and closing the connection cover 30 is provided.

For this purpose, the projection 22d is bent about 90 degrees.

  When the cover switch 22 moves in a sliding manner with respect to the sub-main body 12, the cover switch 22 is provided with a torsion spring so as to feel a sense of operation for the user and to provide resilience to the on or off position. It is supported via a return spring 60 of the form. For this purpose, the cover switch 22 includes a coupling hole 22e for coupling with the free end of the return spring 60. In an embodiment of the present invention, the coupling hole 22e is formed at a position penetrating the protrusion 22d of the cover switch 22. That is, the return spring 60 is installed so that the one end side fixed end portion is supported at an appropriate fixing position with respect to the sub-main body 12, and the other end side free end portion is the coupling hole 22 e of the cover switch 22. By being fixed inside, it is possible to provide operational feeling and resilience when the cover switch 22 is moved in the vertical direction. In particular, the return spring 60 further moves upward with respect to the cover switch 22 when the free end of the other end side deviates more than a specific angle with respect to the sub-main body 12 around the fixed end of the one end. Providing a moving elastic force that allows movement, and if it deviates below a certain angle, it provides a restoring elastic force that allows it to move downward and restore to its original position. .

  Further, the support plate 22c of the cover switch 22 has a mist injection hole 22f opened so as to be able to communicate with the outlet of the nozzle shaft 34 of the ultrasonic oscillator 14, and a magnetic 62 below the mist injection hole 22f. A mounting hole 22g is provided. At this time, the mist injection hole 22f is converted to a state in which it can communicate with the outlet of the nozzle shaft 34 of the ultrasonic oscillator 14 when the cover switch 22 is moved up to the switch-on state. The mounting hole 22g is configured to allow a magnetic sensor (not shown) to detect when the cover switch 22 is moved up to the switch-on state. This is for installation of the magnetic 62. That is, the magnetic 62 is to detect a magnetic sensor provided on the circuit board 18 when the cover switch 22 is moved up to the switch-on state. This operation corresponds to a kind of magnetic switch that enables the liquid to be ejected by the ultrasonic oscillator 14.

  As shown in FIGS. 9, 10, and 12, the hinge lever 24 is a member that is rotatably installed with respect to the sub-main body 12, and that pivots by contact with the protruding portion 22 d as the cover switch 22 is raised. The rotary shaft 24a is pivotably coupled to the sub-main body 12, and is extended to receive pressure by contact with the protruding portion 22d of the cover switch 22 at one end around the rotary shaft 24a. A pressure receiving portion 24b and a pressurizing portion 24c projecting outward for switching the opening and closing of the vent hole opening / closing adjustment portion 26 at the other end centering on the rotating shaft 24a are provided.

  In this case, as shown in FIGS. 9 and 10, the sub-body 12 is coupled to the coupling groove 22b formed between the gripping portion 22a of the cover switch 22 and the support plate 22c, and the cover switch 22 is An installation portion 12a that protrudes in the up-down direction so as to be slidable, a solid boss portion 12b that protrudes for pivotal support of the one end side fixed end portion of the return spring 60, and the left and right side sub-main body 12 The screw-type hollow boss portion 12c protruded for assembly, the hollow-type boss portion 12d protruded for supporting the rotary shaft 24a of the hinge lever 24, and the ultrasonic oscillator 14 installed. A fixing hole 12e having a shape opened for the purpose and a through hole 12f that allows the pressurizing portion 24c of the hinge lever 24 to appear and disappear are provided. Here, the installation portion 12 a serves to guide a fixed position when the cover switch 22 moves in the vertical direction with respect to the sub-main body 12.

  As shown in FIGS. 10, 13, and 14, the vent opening / closing adjustment unit 26 is installed in the first communication portion 16 a of the storage tank 16, and the inside and outside of the storage tank 16 are operated by the operation of the hinge lever 24. By communicating with each other, the air inflow passage corresponding to the passage allowing the outside air to freely flow in and out is selectively opened. For this purpose, the air vent opening / closing adjustment part 26 is installed in the first communication part 16a to open and close the air inflow passage, and the back surface of the air vent packing 26a is elastically supported to always open the air inflow passage. An air vent spring 26b that biases in the closing direction is provided.

  At this time, the first communication portion 16a of the storage tank 16 is formed by a separate housing 16c for accommodating the air vent packing 26a and the air vent spring 26b, and the housing 16c includes the first communication portion 16a. A vent hole 16d for communicating the portion 16a and the inside of the storage tank 16 is formed separately. The air vent packing 26a includes a body 26c having an opening 26d formed on the back surface for receiving a free end portion of the air vent spring 26b in the housing 16c, and the hinge on the front surface of the body 26c. A pressure receiving portion 26e protruding so as to be pressurized by the pressure portion 24c of the lever 24, and an airtight action so as to protrude radially outwards over the entire circumference of the pressure receiving portion 26e to seal the air inflow passage in the housing 16c. An airtight portion 26f is provided.

  As shown in FIGS. 1 to 4, the injection switch 28 is installed in a form exposed to the outside from the side of the lower main body 10, and inputs a signal to the circuit board 18 when pressurized by a user. Then, the ultrasonic vibration action by the ultrasonic oscillator 14 is started.

  Hereinafter, a series of operation processes for using the mist sprayer according to the present invention will be described in order.

  When an upward operating force is applied to the gripping portion 22a of the cover switch 22 that is movable in the vertical direction with respect to the sub-main body 12, the magnetic 62 installed in the mounting hole 22g of the cover switch 22 also rises together. When this is detected by a magnetic sensor provided on the circuit board 18, a preparation stage for mist injection is started.

  At this time, the installation portion 12a formed on the sub-main body 12 serves to guide the coupling groove 22b formed between the grip portion 22a of the cover switch 22 and the support plate 22c to a fixed position. The spring 60 provides an operating elastic force that makes the user who operates the cover switch 22 feel a feeling of operation and raises the cover switch 22 completely upward. Further, with the cover switch 22 completely moved upward, the position of the mist injection hole 22f formed in the cover switch 22 is changed to the same position as the outlet position of the nozzle shaft 34 of the ultrasonic oscillator 14. .

  In this process, the protrusion 22d of the cover switch 22 transmits the operating force to the pressure receiving portion 24b of the hinge lever 24, so that the hinge lever 24 is centered on the rotation shaft 24a with respect to the sub-main body 12. Thus, the pressure portion 24c of the hinge lever 24 is rotated in the counterclockwise direction (reference to FIG. 10), so that the pressure of the air vent packing 26a installed in the housing 16c communicating with the first communication portion 16a of the storage tank 16 is received. The applied pressure is transmitted to the portion 26e.

  As a result, the vent opening / closing adjustment part 26 provided in the first communication part 16a of the storage tank 16 is switched from the closed state to the open state, so that atmospheric pressure acts on the inside of the storage tank 16. become able to. That is, the air vent packing 26a contracts the air vent spring 26b while retreating due to the operating force applied from the hinge lever 24, whereby the airtight portion 26f of the air vent packing 26a opens the first communication portion 16a. Therefore, the external air can flow into the storage tank 16 through the first communication portion 16a through the vent hole 16d formed in the housing 16c.

  Next, when the injection switch 28 is operated, the circuit board 18 supplies the power of the battery 20 to the piezo element 36 of the ultrasonic oscillator 14. At this time, in the ultrasonic oscillator 14, the liquid stored in the storage tank 16 is atomized by the ultrasonic wave generated by the vibration generated between the wave washer 46 and the flat washer 48, and is passed through the outlet of the nozzle shaft 34. It will be injected outside. That is, when the mist sprayer is used, the air inflow passage formed in the first communication portion 16a of the storage tank 16 is artificially opened, and the atmospheric pressure due to the external air is continuously applied to the inside of the storage tank 16. Thus, the mist can be continuously and gently sprayed from the ultrasonic oscillator 14 installed so as to be able to communicate with the second communication portion 16b of the storage tank 16 to the outside. In this process, the mesh 50 installed at the outlet of the nozzle shaft 34 further promotes the atomization of the mist sprayed to the outside, thereby further improving the skin beauty effect.

  When the cover switch 22 is lowered downward after the series of mist injection processes, the external force due to the operating force applied to the pressure receiving portion 24b of the hinge lever 24 is lost and the hinge lever 24 is turned off. The external force applied to the air vent packing 26a is also lost together. As a result, in the vent opening / closing adjustment part 26, the air vent packing 26a closes the first communication part 16a of the storage tank 16 to the original state by the restoring force of the air vent spring 26b.

  As a result, in the storage tank 16, the air continuously flowing in from the outside is blocked by the opening of the first communication portion 16a, so that the phenomenon of liquid leaking outside the device after the mist injection is finished is eliminated. Will be able to. That is, since the atmospheric pressure acting in the storage tank 16 during the mist injection is shut off simultaneously with the operation of the cover switch 22 due to the end of the injection, the external leakage of the liquid stored in the storage tank 16 is further reduced. It can be actively blocked.

  As described above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above, and is generally known in the technical field to which the present invention belongs. It goes without saying that various modifications and variations can be made by those who have the technical scope of the present invention and within the equivalent scope of the claims disclosed below.

  The present invention can be applied to a mist sprayer having a vent opening / closing adjustment function that automatically switches the storage tank side vent opening / closing in conjunction with the opening / closing operation of the cover switch.
