[0010] Beneficial effects

[0011] This invention provides a portable ultrasonic spray device for multi-layered eye protection and anti-pollution. Compared with existing technologies, it has the following advantages: This invention uses arc-shaped patches between the protective shell and the cap. After the cap is adjusted to a fixed distance, several arc-shaped patches can extend forward simultaneously, centrally surrounding the ultrasonic atomizing nozzle. This allows the arc-shaped patches to form a simulated eye socket, providing visual and sensory reference for subsequent eye spraying and preventing spray deviation. Furthermore, the cap covers the ultrasonic atomizing nozzle, and a cotton wiping plate is placed on the front of the cap's inner cavity. When the ultrasonic atomizing nozzle is not in use, the cap can be reset for protection, and the cotton wiping plate can be reset to clean any residual medication from the nozzle, preventing contamination and achieving multi-layered protection.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-7 This utility model provides a technical solution: a portable multi-protection anti-pollution ultrasonic spray device for the eyes, including a protective shell 1, a sprayer 2 and a cap 3. The sprayer 2 is fixedly installed inside the protective shell 1, and the cap 3 is slidably installed on the surface of the sprayer 2. An ultrasonic atomizing nozzle 4 is provided on the front side of the sprayer 2.

[0022] Furthermore, to prevent spray deviation and facilitate the lifting and positioning of the cap 3, arc-shaped frames 5 are fixedly connected to both sides of the protective shell 1 and the cap 3. Arc-shaped patches 6 are slidably connected inside the arc-shaped frames 5. A return spring 7 is fixedly connected between the arc-shaped patches 6 and the arc-shaped frames 5. A linkage plate 8 is rotatably connected to the opposite side of the two arc-shaped patches 6 on the same side, and the two linkage plates 8 are rotatably connected by a rotating pin. A roller 9 is rotatably connected to one side of the arc-shaped patches 6. An extrusion inclined plate 10 matching the roller 9 is fixedly connected to both sides of the sprayer 2. A limit sleeve 11 is fixedly connected to both sides of the cap 3 by opening an installation groove. A limit push-pull rod 12 is slidably connected inside the limit sleeve 11, and a limit spring 13 is fixedly connected between the limit push-pull rod 12 and the limit sleeve 11. A positioning slot 14 matching the limit push-pull rod 12 is opened on both sides of the sprayer 2, and two positioning slots 14 are set up vertically on the same side.

[0023] As a detailed explanation, the front side of the arc-shaped patch 6 is provided with a limiting sliding hole 18 that extends to the rear side, and there are two limiting sliding holes 18. The rear side of the inner cavity of the arc-shaped frame 5 is fixedly connected with a limiting sliding rod 19 that slides and adapts to the limiting sliding hole 18.

[0024] In order to facilitate the cleaning of the ultrasonic atomizing nozzle 4, a cotton wiping plate 15 for use with the ultrasonic atomizing nozzle 4 is installed on the front side of the inner cavity of the cap 3.

[0025] To prevent accidental activation of the control button 16, the rear side of the sprayer 2 is equipped with a control button 16 that is used in conjunction with the ultrasonic atomizing nozzle 4, and the rear side of the cap 3 is fixedly connected with an arc-shaped rear cover plate 17 that is used in conjunction with the control button 16.

[0026] In use, disengage the limiting push-pull rod 12 from the bottom positioning slot 14, then pull the lifting cap 3 until the limiting push-pull rod 12 and the top positioning slot 14 are aligned. As the cap 3 rises, it simultaneously raises the top arc frame 5 and the arc patch 6 until the ultrasonic atomizing nozzle 4 is exposed and positioned at the center of the four arc frames 5. The top arc patch 6 rises and moves, simultaneously driving the roller 9 to engage with the extrusion inclined plate 10, causing the extrusion inclined plate 10 to drive the top arc patch 6 to extend forward. Simultaneously, the top arc patch 6 extends forward, and the bottom arc patch 6 extends forward through the linkage plate 8, ultimately forming an eye socket outline. Then, push the device forward to ensure that the eye socket outline formed by several arc patches 6 fits properly around the eye socket where medication needs to be applied. Finally, press the control button 16 to spray medication onto the eye using the ultrasonic atomizing nozzle 4.
