[0039] Please refer to Figures 1 to 6In an embodiment of the present application, the sealing device 200 comprises a sealing cover 201, the main body 100 is provided with a receiving groove 202 corresponding to the liquid injection hole 104, the sealing cover 201 is detachably installed in the receiving groove 202, and the sealing cover 201 is fixedly connected with a sealing plug 203 corresponding to the liquid injection hole 104. The sealing plug 203 is detachably inserted into the liquid injection hole 104. The sealing plug 203 can seal the liquid injection hole 104. The receiving groove 202 can ensure that the sealing cover 201 is more stably installed on the main body 100.

[0040] Please refer to Figures 1 to 6 In an embodiment of the present application, the sealing cover 201 is fixedly connected with a mounting column 204 on one side close to the receiving groove 202, the main body 100 is provided with a mounting hole 205 corresponding to the mounting column 204 in the inside of the receiving groove 202, and the mounting column 204 is rotatably inserted into the mounting hole 205. In this way, when the sealing plug 203 and the sealing cover 201 are removed, the sealing cover 201 can still be connected to the main body 100, which facilitates the installation and removal operation and prevents the sealing cover 201 from being lost.

[0041] In an embodiment of the present application, the sealing cover 201, the sealing plug 203 and the mounting column 204 are integrally formed by using an elastic material, such as silica gel or rubber material. The elastic material can not only ensure the sealing effect of the sealing plug 203 on the liquid injection hole 104, but also ensure the connection stability between the sealing cover 201 and the receiving groove 202. In addition, the elastic material can make the mounting column 204 have good flexibility, thereby avoiding fatigue damage during the installation and removal process.

[0042] Please refer to Figures 1 to 6 In an embodiment of the present application, the main body 100 is provided with an air hole 206 in the inside of the receiving groove 202, which is in communication with the liquid storage cavity 101. The inside of the receiving groove 202 is provided with an inclined table 207 on the outside of the air hole 206. One end of the sealing cover 201 is arranged on the inclined table 207 to form a gap in communication with the air hole 206. The air hole 206 and the gap can avoid the difficulty of liquid absorption caused by the negative pressure in the liquid storage cavity 101 when the suction device 300 absorbs the liquid. In addition, the gap can make the operation of removing the sealing cover 201 more convenient.

[0043] Please refer to Figures 1 to 6 In an embodiment of the present application, the suction device 300 comprises a long strip 301 made of soft and water-absorbing material, such as medical sponge or cotton. The long strip 301 is partially filled in the liquid suction cavity 102 and partially exposed outside the liquid suction cavity 102.

[0044] In an embodiment of the present application, the long strip 301 can also be made of plant fiber processed into pulp fiber material, medical non-woven fabric made of polypropylene and other polymer materials, and other materials or devices having water absorption performance.

[0045] Referring to Figures 1 to 6 In an embodiment of the present application, the cross section of the liquid absorption cavity 102 is circular, and the cross section of the long strip 301 is also circular. The central angle of the part of the long strip 301 exposed outside the liquid absorption cavity 102 is α, which satisfies 80°<α<120°. In actual use, when the central angle of the part of the long strip 301 exposed outside the liquid absorption cavity 102 is greater than 120°, the stability of the long strip 301 installed inside the liquid absorption cavity 102 will decrease, and the long strip 301 will easily slide out of the liquid absorption cavity 102. When the central angle of the part of the long strip 301 exposed outside the liquid absorption cavity 102 is less than 80°, the smearing area of the long strip 301 exposed outside will decrease, thereby reducing the smearing effect of the liquid medicine.

[0046] Referring to Figures 1 to 6 In an embodiment of the present application, the handle 400 includes an arc-shaped hand holding portion 401, which facilitates holding during operation. One end of the hand holding portion 401 is fixedly connected to an integrally formed mounting portion 402, which is inserted into the handle mounting cavity 103. A buckle structure for clamping the main body 100 is arranged at the connection between the mounting portion 402 and the hand holding portion 401, which can ensure the connection strength between the handle 400 and the main body 100.

[0047] Referring to Figures 1 to 6 In an embodiment of the present application, the buckle structure includes a clamping seat 403 fixedly connected to the connection between the mounting portion 402 and the hand holding portion 401. Arranging the clamping seat 403 at the connection between the mounting portion 402 and the hand holding portion 401 can not only increase the connection strength between the mounting portion 402 and the hand holding portion 401, but also facilitate operation during installation or disassembly. A clamping groove 404 is arranged on the clamping seat 403, and a clamping hook 405 corresponding to the clamping groove 404 is arranged on the end cover 107. The clamping hook 405 buckled in the clamping groove 404 can increase the connection stability between the end cover 107 and the handle 400, thereby ensuring the stability and reliability of the medicine dispenser during use.

[0048] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered by the protection scope of the present application.
