Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to an easily detachable eye ultrasonic atomizer. Background Art

[0002] With the increasing popularity of electronic products, the number of patients with dry eyes is gradually increasing and tends to be younger. The efficacy of dry eye treatment can be significantly increased through atomization heating fumigation and drug penetration therapy. The existing technology usually uses a single-chip piezoelectric ceramic transducer to atomize the liquid using ultrasound, and then deliver it to the eye after heating. The ultrasonic atomizer composed of a single-chip piezoelectric ceramic transducer is currently the most common and earliest ultrasonic atomization method. This technology uses a piezoelectric ceramic transducer to vibrate and emit ultrasonic waves in the liquid. When the ultrasonic wave is transmitted to the interface between the liquid and the air, due to the huge difference in acoustic impedance of different media, the ultrasonic energy will quickly gather at the interface and eventually tear the liquid into tiny droplets to form atomization. The atomizers currently used usually install a single-chip piezoelectric ceramic transducer on the atomizing water tank and make it an integral structure with the atomizer host. The water tank in the atomizer will produce scale after long-term use. In particular, the atomizer needs to be heated during use, which will also cause scale to form faster. The integral design makes it inconvenient to clean and disinfect the tank. At the same time, the single-chip piezoelectric ceramic transducer has an inherent characteristic. After 2000-3000 hours of use, the mist output will gradually decay by 30%-40%. Calculated based on the equipment working 8 hours a day and 300 days a year, after two years, the mist output of the single-chip piezoelectric ceramic transducer will decay by more than 50%. Once a component is damaged, it is inconvenient to replace and repair it, and the entire device may even have to be scrapped. Therefore, the design service life of some medical ultrasonic atomizers does not exceed three years. Utility Model Content

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] like Figure 1-Figure 5 As shown, this example provides an easily detachable eye ultrasonic nebulizer, including: a main body 100 and a tank body 200.

[0023] A recess 101 is provided on one side of the main body 100, a recess 102 is provided at the bottom of the recess 101, a limiting groove 103 is also provided on one side of the recess 101, and the limiting groove 103 extends to the bottom of the recess 102; the tank body 200 is installed in the recess 102, and an atomizer cup 201 is provided inside for containing liquid medicine, the upper end of the atomizer cup 201 is overlapped with the upper edge of the tank body 200, and a top cover 202 is also provided on the upper end of the tank body 200, at least a part of the lower end of the top cover 202 is located in the atomizer cup 201, and a connecting ring 203 is provided on the outer wall of the top cover 202, and the connecting ring 203 is matched with the upper end of the tank body 200, and a vertical portion 204 is also provided on the outer side of the tank body 200, and the vertical portion 204 is matched with the limiting groove 103, and the tank body 200 can be taken out of the recess 102 by taking the vertical portion 204 out of the limiting groove 103.

[0024] Specifically, limiting strips 104 are provided on both sides of the limiting groove 103, and clamping strips 215 are provided on both sides of the vertical portion 204. When the can body 200 is placed in the groove 102, the clamping strip 215 is located between the limiting strip 104 and the side of the limiting groove 103, thereby clamping the can body 200.

[0025] Specifically, the bottom of the atomizer cup 201 is arc-shaped, and a support ring 205 is provided at the upper end. A ring groove 206 is provided at the bottom of the support ring 205, and a positioning ring 207 is provided at the upper end of the tank body 200. When the atomizer cup 201 is placed in the tank body 200, the positioning ring 207 cooperates with the ring groove 206, thereby clamping the atomizer cup 201 in the tank body 200.

[0026] Specifically, a clamping ring 208 is further provided at the upper end of the tank body 200, and the cross-section of the clamping ring 208 is L-shaped. A convex ring 209 is provided at the bottom of the connecting ring 203 along the circumferential direction. The convex ring 209 cooperates with the inner wall of the clamping ring 208 to clamp the top cover 202, and the bottom of the convex ring 209 abuts against the supporting ring 205 to prevent the equipment from shaking and causing the positioning ring 207 to be out of fit with the annular groove 206, thereby causing the atomizer cup 201 to tip over.

[0027] Specifically, an annular protrusion 210 is further provided on the bottom surface of the convex ring 209 along its circumferential direction. The protrusion 210 is located between the inner wall of the clamping ring 208 and the support ring 205 to limit the circumference of the support ring 205 and further ensure the stability of the atomizer cup 201.

[0028] Specifically, the top of the top cover 202 is connected to the mist delivery pipe, and a plurality of protrusions 211 are provided along the circumferential direction at the bottom of the top cover 202. There is a spacing between the outer wall of the protrusion 211 and the inner wall of the atomizer cup 201 to form a spoiler mechanism, so that the lateral air intake is blocked by the spoiler mechanism and then changes direction, forming a uniform annular airflow from bottom to top along the spoiler ring, blowing the mist to the mist delivery pipe, and preventing the air intake from directly impacting the mist column laterally.

[0029] Specifically, the vertical portion 204 is provided with an air inlet 212 that passes through the upper end, and a through hole 213 is provided at the lower end of the air inlet 212 for communicating with the main body 100. A U-shaped portion 214 is also provided at the bottom of the connecting ring 203. The two sides of the U-shaped portion 214 are connected to the convex ring 209, and the lower end of the U-shaped portion 214 is connected to the air inlet 212 to form an air inlet. When in use, gas is introduced from the main body 100 into the air inlet 212 through the through hole 213, and then the gas enters the atomization cup 201 through the air inlet, thereby starting to atomize the medicine liquid.

[0030] Specifically, a water level sensor is provided at the bottom of the tank body 200 to monitor the liquid level in the tank body 200 in real time to avoid the situation where the liquid level is too low and the temperature is too high. A horizontal bar is provided on the side wall of the tank body 200, which is a water level line, to facilitate observation of the water level in the tank body 200 so that water can be added in time.

[0031] Since the above are only preferred embodiments of the present invention and are not intended to limit the present invention, it is obvious that those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
