Abstract
Description
[Technical Field]
[0001] The present invention relates to a hot water sprayer that produces hot water at an appropriate temperature without using cold water. [Background technology]
[0002] Traditionally, when you wanted to wipe your body, you would put hot water in a washbasin, dilute it with water to make it the right temperature, and then use it to wipe your body. [Patent documents] DISCLOSURE OF THE INVENTION Problem to be solved by the invention
[0003] When you find yourself in a situation where you have to live in evacuation shelters for a long time, there will be no baths at the evacuation shelter, and you will want to take a bath. Babies, in particular, are prone to diaper rash. One method is to put hot water from a kettle or water boiled on a portable stove into a washbasin and use it to wipe their bodies, but this requires a large amount of hot water and water, and is impossible to do in a small space. The present invention has been made to solve the above problems.
[0004] The nozzle of the sprayer is provided with a groove and string to prevent the nozzle from falling off. A hot water tank is provided. A hole to prevent loosening is provided on the side of the hot water tank mounting cap. A receiving tube is provided on the top of the hot water tank to connect the hole to the hole. A pin is provided to secure the connection. A hot water tank case is provided to prevent heat loss from the hot water tank. A lantern-shaped funnel is provided for pouring hot water into. A groove is provided around the circumference of the funnel's inlet. The bottom periphery of the hot water tank case is fitted into the groove in the funnel, and the funnel is placed around the inside of the bottom periphery of the hot water tank case. Hooks for shoulder hanging are provided on the left and right sides of the hot water tank case. Effects of the hot water sprayer invention having the above configuration
[0005] This device instantly turns boiling water to the right temperature without using water, something that was previously impossible, and can be sprayed directly onto the skin or onto a towel to create a steamed towel. Because it uses a spray method, no water is wasted, so only a small amount of water is needed, and the temperature and amount of water can be adjusted with the nozzle, making it easy to carry. It can also be slung over the shoulder for easy use. The present invention is safe and comfortable to use. BEST MODE FOR CARRYING OUT THE INVENTION
[0006] Hereinafter, an embodiment of the present invention will be described. (a) The nozzle (2) of the hot water sprayer (1) is provided with a groove (3) and a string (5) for preventing the nozzle from falling off. (b) A hot water tank (10) is provided. (c) A hole (7) is provided on the side of the hot water tank mounting cap (6) to prevent loosening. (d) A receiving tube (11) is provided on the top of the hot water tank (10) to connect with the locking hole (7). (e) A pin (15) is provided to fix the connection. (f) A hot water tank case (8) is provided to prevent heat dissipation from the hot water tank (10). (g) A lantern-shaped funnel (12) is provided for pouring hot water. (h) A groove (13) is provided around the inlet of the funnel (12). TIFF2025160068000002.tif12162The funnel (12) fits around the inside of the bottom edge.Hooks (17) are provided on the left and right sides of the case for carrying it over the shoulder. (Ri) Make hot water at the right temperature without using cold water. The present invention has the above structure. When using the present invention, remove the funnel (12) from the bottom of the hot water tank case (8). Stretch out the contracted funnel (12) and fit it into the hot water tank inlet (10). Pour boiling water from a pot (16) into the hot water tank (10) until it reaches a uniform temperature, then close the hot water tank cap (6). Once the cap (6) is fully closed, align the locking hole (7) with the receiving tube (11) and insert the pin (15) to secure it in place. This prevents it from falling off, and it is ready to use. Operate the lever (4) several times to remove any air. Once the air has been removed, spray directly onto the palm of your hand, check that it is at the right temperature, and then use it. When spraying directly onto the skin, spray the water precisely and then wipe it off with a towel. When using it as a steamed towel, spray the water evenly over the towel. The water temperature and amount can be adjusted by rotating the nozzle (2). The hot water sprayer (1) puts hot water into the hot water tank (10), but the hot water tank case (8) blocks heat radiation, eliminating the risk of burns. It maintains the water temperature for a long time and only requires a small amount of water, making it easy to carry, simple to operate, and space-saving. Even just wiping the body can be soothing, especially in evacuation shelters without baths or at nursing care sites. It can also be worn over the shoulder, leaving both hands free for easy use.
