Referring to Figures 1-5, the hand cleaning and disinfecting device includes a fixing belt A0 and a liquid storage and spray device A1; the fixing belt A0 can be put on a person's wrist; the liquid storage and spray device A1 is fixed on the The fixing belt A0. When in use, the fixing belt A0 of the present application can be worn on the user's wrist. When the disinfectant needs to be sprayed for hand disinfection, only the liquid storage spray device A1 needs to be triggered to complete the spraying of the disinfectant. clean and disinfect. The connection between the liquid storage and spray device A1 and the fixing belt A0 can be a detachable connection; the liquid storage and spray device A1 can be a pressing nozzle or an electric nozzle; the liquid storage and spray device includes a liquid spray button 11, a nozzle 12, and a movable pump It is composed of core 13, buckle cover 14, and base 15;

The inside of the base 15 is a cavity for storing liquid. The upper end of the base 15 is open; the buckle cover 14 is detachably fixed to the opening of the base 15; the spray button 11 and the buckle cover 14 can be Sliding connection; the sliding stroke of the spray button 11 is limited by the V-shaped groove on the side of the buckle cover 14, the movable pump core 13 is fixedly connected to the buckle cover 14, and the spray button 11 can be slidably fixed to the movable pump At the liquid outlet end of the core 13, a number of convex points 115 are provided on the side of the spray button 11, a number of grooves provided on the side of the buckle cover 14 are V-shaped, and the top of the adjacent V-shaped grooves is connected with downwards. The convex point 115 of the liquid spray button 11 slides in the V-shaped groove of the buckle cover 14, and the several convex points 115 of the liquid button 11 are elastic convex points.

A first sleeve 111 is provided inside the spray button 11; the sleeve is hollow, one end of the movable pump core 13 communicates with the inside of the first sleeve 111, and the edge of the spray button 11 is one There is a first protrusion 113 on the side, the first protrusion 113 is provided with a hollow channel, the first protrusion 113 is arrow-shaped, the first protrusion 113 of the spray button 11 and the first sleeve 111 Internally connected, the first protrusion 113 is fixedly connected to the nozzle 12, the first protrusion 113 is used to indicate the direction of spraying liquid, and the spray button 11 has an arrow on the edge and the other side has an arrow tail. The first sleeve 111 is slidably sleeved on the liquid outlet end of the movable pump core 13; the buckle cover 14 has a hollow cylindrical first groove 141 in the center, and the movable pump core 13 is fixed in the first cylindrical groove 141 of the buckle cover 14; the liquid suction port of the movable pump core 13 is arranged in the cavity of the base 15.

A convex second sleeve 112 is provided on the inner side of the first sleeve 111 on the inner side of the spray button 11, and an annular second groove 142 is provided on the outer side of the central cylindrical first groove 141 of the buckle cover 14. The second sleeve 112 is slidably connected to the second groove 142.

The opening of the buckle cover 14 and the base 15 is a detachable sealed connection.

Working principle: Disinfectant is stored in the base 15 and the buckle cover 14 and the cavity in the base 15 form a closed space to prevent the disinfectant from leaking; when the spray button 11 is pressed vertically, the two sides of the spray button 11 The convex points of the buckle cover 14 and the adjacent V-shaped groove are connected to the top recess, so that the spray button 14 cannot be pressed, thereby preventing false triggering. When the spray button 11 is rotated and pressed down, the spray button 11 is sprayed. The convex points on both sides of the button 11 can be relatively movable in the V-shaped groove of the buckle cover 14. The second sleeve 112 of the liquid spray button 11 and the second groove 142 of the buckle cover can be slidably connected to guide the axial movement. The space enclosed by the pump core 13 becomes smaller, and the disinfectant inside is squeezed, and then sprayed from the nozzle 12 through the spray channel 11. When the spray button 11 is released, the movable pump core 13 resets and sprays When the liquid button 11 moves upward, the space enclosed by the movable pump core 13 becomes larger, and the liquid below is sucked.

Example 2

Referring to Figures 6-10, the hand cleaning and disinfection device includes a fixing belt A0 and a liquid storage spray device B2; the fixing belt A0 can be put on a person's wrist; the liquid storage spray device B2 is fixed on the The fixed belt A0; the liquid storage and spray device includes a liquid spray button 21, a nozzle 22, a movable pump core 23, a buckle cover 24 and a base 25, which is different from Embodiment 1. The arrow state of the liquid spray button 21 is the second A protrusion 213 has no arrow-shaped protrusion on the other side; the buckle cover 24 has a cylindrical first sleeve 211, and the inner sleeve is placed on the liquid spray button 21. A number of grooves provided on the side of the buckle cover 24 are strip-shaped, and a number of convex points 214 are provided on the side of the spray button 21. The convex points 214 slide in the strip-shaped grooves of the buckle cover. The protrusions 214 of the liquid button 21 are elastic protrusions.

Working principle: When the spray button 21 is pressed in the vertical direction, the convex points on both sides of the spray button cooperate with the groove of the buckle cover 24 to form a guiding effect. The spray button 21 can move up and down, but the left and right rotation is subject to resistance Rotate the spray button 21 to overcome the deformation of the convex points on both sides of the spray button 21 so that the spray button 21 rotates. The second sleeve 212 of the spray button 21 is slidably connected with the second groove 142 of the buckle cover to act as an axial guide. The space enclosed by the movable pump core 23 becomes smaller, and the disinfectant inside is squeezed, and then sprayed from the nozzle 22 through the spray pressing channel. When the spray button 21 is released, the movable pump core 23 is reset, The liquid ejection button 21 moves upward, and the space enclosed by the movable pump core 23 becomes larger, and the liquid below is sucked.

The application is worn on the user's wrist. When it is necessary to spray the disinfectant on the hand, press the spray button continuously, and the disinfectant will be sprayed through the nozzle and sprayed onto the hand. The application is worn on the user's wrist, which avoids other contact transmission and is more convenient to use.

The buckle cover and the opening of the base are detachably sealed in connection. In this way, the disinfectant can be filled by removing the buckle cover.

The spray button can be rotated with resistance relative to the fixing belt. In this way, the user can adjust the nozzle to a proper position by turning the spray button before spraying the disinfectant, and during spraying, the spray range of the disinfectant can be conveniently increased.

The disinfectant can be a disposable disinfectant, which is more convenient to use.

The present invention has the functions of preventing non-spraying and guiding, so the present application has good practical value and safety.

The above-mentioned embodiments and drawings do not limit the product form and style of this application, and any appropriate changes or modifications made by a person of ordinary skill in the art should be regarded as not departing from the patent scope of this application.
