[0002] Currently, after surgical operations, it is generally required to keep the wound dry and avoid contact with water to prevent infection. Therefore, patients are required not to wash their hair or take a shower after surgery. In particular, for ear surgeries (such as endoscopic ear surgery, open mastoid surgery, auricular debridement and suture), patients are required to avoid contact with water for two weeks. Therefore, most patients need to abstain from washing their hair for two weeks, which causes great inconvenience to patients. A small number of patients choose to purchase common earmuffs (such as hard plastic earmuffs, soft plastic films, etc.) on the market for protection before taking a shower. However, these types of earmuffs are ineffective and easily get water in, causing infection. In view of this, the present invention was developed. Utility Model Content

[0021] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.
[0022] like Figures 1-6 As shown, this embodiment provides a waterproof earmuff for use after ear surgery, including an earmuff 1, a mounting frame 2, a transverse tightening band 3, a longitudinal tightening band 4 and a connecting slider 5.
[0023] The mounting frame 2 has a mounting notch in the middle, into which the earmuff 1 is mounted. A sealing bead 11 is formed at the edge of the opening of the earmuff 1. The earmuff 1 is a curved cover, secured to the mounting frame 2 by adhesive. Specifically, a concave ring is formed between the earmuff 1 and the sealing bead 11, within which the mounting frame 2 is positioned. Arc-shaped hanging holes 21 are formed on the left and right sides and the top and bottom sides of the mounting frame 2.
[0024] The two ends of the transverse tightening band 3 are respectively detachably connected to the left and right sides of the mounting frame 2; a first hanging buckle 31 is provided at both ends of the transverse tightening band 3, and the first hanging buckle 31 is adapted to the hanging hole 21. The first hanging buckle 31 is a plastic buckle, and the first hanging buckle 31 includes a long vertical plate 311, two transverse plates 312 and two short vertical plates 313. The two transverse plates 312 are connected to the two ends of the long vertical plate 311 and face the same direction, and the two short vertical plates 313 are respectively connected to the ends of the two transverse plates 312 and face each other. The distance between the two short vertical plates 313 is less than the thickness of the mounting frame 2, and flared chamfers 314 are formed on both sides of the ends of the short vertical plates 313. The first hanging buckle 31 is clamped into the hanging hole 21 through deformation. The thickness of the first hanging buckle 31 is less than the length of the arc-shaped hanging hole 21, so setting the first hanging buckle 31 can make it movable and adjustable in the hanging hole 21. When the transverse tightening belt 3 is in a tightened state, the opening formed by the two short vertical plates 313 is staggered with the thin wall of the installation frame 2, and no stripping phenomenon will occur.
[0025] The connecting slider has a through hole 53, and the transverse tightening belt 3 passes through the through hole 53; a flexible pad 54 is provided on the inner side of the connecting slider 5, and the flexible pad 54 is made of silicone and is connected to the surface of the connecting slider 5 by bonding. A snap notch 51 is formed on one side of the connecting slider 5, and a snap column 52 is provided in the snap notch 51, and the hook portion of the hook 43 is locked on the inner side of the snap column 52.
[0026] One end of the longitudinal tightening band 4 is removably connected to the bottom of the mounting frame 2. Specifically, it has a second hook 42 that fits into the hanging hole 21. The second hook 42 has the same structure as the first hook 31, and its thickness is less than the length of the arc-shaped hanging hole 21. This allows for adjustable movement within the hanging hole 21. The other end of the longitudinal tightening band 4 is removably connected to the connecting slider 5. Specifically, it has a hook 43, the curved portion of which is secured to the inside of the post 52 via the hook. A chin pad 41 is provided on the longitudinal tightening band 4. The chin pad 41 has a sliding opening through which the longitudinal tightening band 4 passes, enhancing wearer comfort.
[0027] Working principle: the earmuff 1 is fixedly set in the mounting frame 2, the two ends of the horizontal tightening belt 3 are connected to the left and right ends of the mounting frame 2, and the two ends of the longitudinal tightening belt 4 are connected to the lower end of the mounting frame 2 and the connecting slider 5 on the horizontal tightening belt 3. First, the earmuff 1 is set on the ear that needs to be protected, and then the loop formed by pulling the horizontal tightening belt 3 is set at the forehead position, and then the connecting slider 5 is adjusted to the back of the ear of the other ear, and then the longitudinal tightening belt 4 is pulled to tie it to the chin position. In this way, the earmuff 1 and the mounting frame 2 are tightened in the horizontal direction by the horizontal tightening belt 3 and in the vertical direction by the longitudinal tightening belt 4, ensuring that the earmuff 1 fits tightly to the skin during shampooing and no water leaks in. The earmuffs of this solution are worn with good waterproof effect and are easy to wear.
