DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0022] See also Figure 1 The present application provides a high-temperature induction shower head, including a shower head body 10 and a splash diffusion structure 20.

[0023] The shower head body 10 is used to sense the ambient temperature, and the splash structure 20 is used to increase the spraying range.

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The sprinkler head body 10 includes a threaded tube 110, a water outlet tube 120 welded to the bottom end of the threaded tube 110, and a sealing plug 130 provided inside the water outlet tube 120. It also includes a groove 140 opened at the bottom of the sealing plug 130 and a temperature sensing part 150 fitted with the groove 140; the temperature sensing part 150 includes a glass ball 151 and an expansion liquid 152.

[0025] Among them, the design of the threaded barrel 110 allows the sprinkler head to be easily connected to a water pipe or other fixing device by rotation without the use of additional tools, thereby greatly simplifying the installation process, and the outer bottom of the threaded barrel 110 can also be set to a rectangle, which is convenient for users to better install the sprinkler head.

[0026] The water outlet tube 120 serves as a liquid channel, which can ensure that water or other liquids can flow out of the threaded tube 110 smoothly, thereby avoiding water flow turbulence or blockage.

[0027] Among them, the design of the sealing plug 130 can seal the water outlet at the bottom of the threaded barrel 110, and the outer wall of the sealing plug 130 fits tightly with the inner ring of the rubber ring 211, so that the outer ring of the rubber ring 211 fits with the inner wall of the threaded barrel 110. This design ensures that water or other liquids are blocked inside the threaded barrel 110.

[0028] Among them, the groove 140 is cleverly arranged at the opposite ends of the sealing plug 130 and the fixing bolt 223. This design detail facilitates the installation of the temperature sensing part 150, and the shape and size of the groove 140 can be adjusted according to specific needs, and the groove 140 can be designed into a polygonal or wavy shape. At the same time, in order to ensure the convenience of installation and disassembly of the temperature sensing part 150, the depth and width of the groove 140 also need to be reasonably designed.

[0029] Among them, the temperature sensing part 150 is mainly composed of a glass ball 151 and an expansion liquid 152. The interior of the glass ball 151 is filled with the expansion liquid 152. This special liquid will produce a volume change when the temperature changes, thereby driving the glass ball 151 to deform. The two ends of the glass ball 151 are tightly fitted with the inner walls of the two grooves 140 respectively. When the temperature changes, the deformation of the glass ball 151 will directly affect the working state of the sprinkler head.

[0030] See also Figure 1 , Figure 2 , Figure 4 The splash expansion structure 20 includes a spraying part 210 and a splashing part 220 installed on the water outlet tube 120; the spraying part 210 includes a rubber ring 211, a plurality of inclined holes 212 and a plurality of spraying pipes 213; the splashing part 220 includes two support rods 221, a splashing plate 222 and a top fixing bolt 223.

[0031] Among them, the design of the spray part 210 directly determines the spray effect and the distribution of water flow, and increases its spray range. The bottom ring of the rubber ring 211 is fixedly connected to the inner bottom of the water outlet cylinder 120, while its top ring is smaller than the bottom ring and extends to the inner top of the water outlet cylinder 120, forming a conical structure. This design is not only conducive to the guidance of water flow, but also can divert water sources into the spray pipe 213 through the inclined holes 212; a number of inclined holes 212 are evenly spaced on the side wall of the water outlet cylinder 120. These holes are arranged obliquely, the purpose is to lead the water flow out of the water outlet cylinder 120 and make it have a certain spray angle. The number and size of the inclined holes 212 can be adjusted according to actual needs to achieve the best spray effect; one end of the plurality of spray pipes 213 is fixedly connected to the inner wall of the plurality of inclined holes 212, and the other end faces different directions. This design enables the water flow to be further diffused and sprayed through the spray pipe 213 after flowing out of the inclined holes 212, thereby achieving a wider coverage range and more uniform water flow distribution.

[0032] Among them, the splashing part 220 is an important component of the sprinkler head. Its main function is to disperse the water flow into fine water droplets and spray it out at a wider angle, so as to increase the coverage and effect of the spray. The two support rods 221 can ensure the stability and positioning accuracy of the splash plate 222. Some auxiliary structures are added to the splash plate 222, such as anti-slip textures or water flow guide grooves, to increase the dispersion and splashing effect of the water flow, and the edge can also be designed to be inclined or wavy to further increase the splashing angle and coverage of the water flow; the top fixing bolt 223 is threadedly connected to the inner wall of the splash plate 222 for fixing the temperature sensing part 150.

[0033] The working principle of the high-temperature induction sprinkler head is as follows: when a fire occurs, the sprinkler head senses the change in external temperature. When the preset threshold is reached, it triggers the expansion liquid 152 to expand, causing the glass ball 151 to deform and break. The sealing plug 130 is flushed out of the water outlet tube 120 by the water pressure, which can reset the rubber ring 211. After the water flows out from the inclined hole 212, it can be further diffused and sprayed through the injection pipe 213. At the same time, the water flow impacts the splash plate 222, thereby increasing the splashing angle and coverage of the water flow, thereby achieving a fire extinguishing effect.

[0034] It should be noted that the specific models and specifications of the temperature sensing part 150, the water splash plate 222, and the injection pipe 213 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0035] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
