Description

Technical Field

[0001] The present invention relates to the field of hand cleaning and disinfection, and particularly to a hand cleaning and temperature measuring device. Background Art

[0002] Through investigation and statistics, on average, a person touches their own cheeks with their hands up to 2,000 - 3,000 times a day, 3 - 5 times per minute when awake. During this period, people will come into contact with door handles, faucets, elevator buttons, etc., and a large amount of bacteria will adhere to their hands. Touching their own cheeks directly will increase the risk of bacteria and viruses on the hands entering the human body through the eyes, nose, mouth, and ears.

[0003] Contact transmission is one of the main transmission routes of bacteria and viruses, and the disinfection and cleaning of hands are very important. Currently, the hand disinfection devices that can be purchased or used on the market all spray disinfectant liquid by pressing a button, but there is no anti - misspray setting. In the case where the user is not paying attention, it is possible to waste disinfectant liquid by pressing the button multiple times (such as the prior art: hand disinfection device: 202010193562.8).

[0004] At the same time, the most common symptom of virus infection is fever and fatigue. Therefore, the most common measurement measure in major public places is to detect body temperature. Currently, the commonly used cleaning tool for people is a small - volume spray disinfection bottle that can be carried around, which can only be used for spray disinfection. When the user suspects that they or nearby people are infected with the virus and need to detect their body temperature, they have to find a separate infrared thermometer or thermometer for detection, and it is impossible to perform real - time tracking of body temperature measurement.

[0049] Please refer to Figure 5As shown, the specific shape of the card slot 237 includes a pressing-down section 2371, a buckling section, and a reset section. The pressing-down section 2371, the buckling section, and the reset section are sequentially distributed in a descending stepped shape. The pressing-down section 2371 is designed as a vertically downward groove. The buckling section communicates with the end of the pressing-down section 2371. The buckling section includes a first guiding section 2372 and a positioning groove section 2373. The first guiding section 2372 communicates with the end of the pressing-down section 2371.

The connecting section 2375 communicates with the waist of the pressing-down section 2371 and the depth of the pressing-down section 2371 is deeper than that of the connecting section 2375.

[0050] The working principle of the secondary pressing of the spray upper cover: The buckle 2221 of the spray upper cover 22 cooperates with the card slot 237 and is located at the top of the pressing-down section 2371 of the card slot 237. When the user presses the spray upper cover 22, the buckle 2221 moves vertically downward along the pressing-down section 2371. When reaching the lowest point of the pressing-down section 2371, it enters the next step, that is, enters the buckling section 2372. At this time, the user releases the hand. The spray upper cover 22 is affected by the spring 272 of the movable pump core and has an upward movement force. The buckle moves along the upper groove wall of the buckling section and finally stops moving at the vertex groove 2377 of the positioning groove section 2373. The position of the spray upper cover is at a low place and the overall device is beautiful.

[0051] When the user applies a downward pressure to the spray upper cover 22 again, the buckle moves downward along the lower groove wall of the positioning groove section 2373 from the vertex groove 2377. When reaching the lower limit position, it enters the next step, that is, enters the reset section. At this time, the external force is removed. The spray upper cover 22 as a whole is again affected by the spring 272 of the movable pump core and has an upward movement force. The buckle sequentially passes through the second guiding section 2374, the inclined platform 2376, and the connecting section 2375 along the upper groove wall of the reset section, and finally enters the next step at the end of the connecting section 2375, that is, returns to the pressing-down section 2371, and then moves vertically upward to complete the reset.

[0052] The working principle of the liquid spraying device of the present invention is as follows: disinfectant is stored in the cavity of the liquid storage base, and the buckle cover is rotated above the open opening of the liquid storage base through the cooperation of the inner and outer threads to form a closed space to prevent the disinfectant in the cavity from leaking out. When the wearer presses the spray upper cover 22 once, the convex buckle of the spray upper cover is pressed down along the track of the card slot, and rebounds and locks at the vertex groove under the action of the spring of the movable pump core. The spray upper cover is at a low position, the space of the cavity inside the first sleeve becomes smaller, the disinfectant in the cavity is squeezed, and the disinfectant is sprayed out from the nozzle through the liquid pipeline and the liquid outlet pipeline;

[0053] When the wearer presses the spray cover for the second time, the convex buckle of the spray cover is pressed down along the track of the card slot and reset to the initial position under the action of the spring of the movable pump core. The spray cover is in a high position, the space of the internal cavity of the first sleeve becomes larger, and the external gas cannot flow in quickly through the nozzle. Therefore, a negative pressure is formed in the internal cavity of the first sleeve for a short time, and the one-way ball valve is turned on. The disinfectant in the liquid storage base flows into the cavity inside the first sleeve through the one-way ball valve. At this time, the volume of the disinfectant in the liquid storage base is reduced, and the internal air pressure of the liquid storage base is reduced. The outside gas enters the liquid storage base through the air inlet hole in the convex column to balance the internal air pressure of the liquid storage base.

[0054] The present invention changes the prior art of one-press liquid discharge into a two-press liquid discharge, so that the device is in a lower position when not in use, ensuring the overall structure is beautiful while preventing the wearer from triggering it by mistake, resulting in waste of disinfectant.

[0055] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
