Description

Technical Field

[0001] The utility model belongs to the field of faucet temperature display instruments, and more specifically, particularly relates to a faucet temperature display instrument which is easy to install. Background Art

[0002] The faucet temperature display is a water temperature display device installed on the faucet. Its function is to visually present the water flow temperature at the faucet outlet in digital form to the user. By observing the numbers on the display screen, the user can clearly understand the water temperature of the faucet output and avoid skin burns from contact with high-temperature water. At present, faucet temperature displays are mostly installed at the faucet outlet with a threaded connection and a waterproof pad. Due to the different calibers of faucet outlets of different brands, the faucet temperature display needs to be specially designed and manufactured with a corresponding threaded connection. It can be seen that the threaded connection structure of the traditional faucet temperature display is relatively fixed, and the temperature display cannot be connected to the output end of faucets of different calibers. It has poor versatility and is inconvenient to install and use. In addition, the temperature measuring probe of the traditional faucet temperature display will contact the water flow for temperature measurement. The surface of the probe will adhere to scale after long-term use, affecting the accuracy of the probe detection. Utility Model Content

[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] like Figure 1-Figure 8 As shown, the utility model provides a faucet temperature display instrument that is easy to install, including a water outlet pipe 2; the water outlet pipe 2 is installed at the water outlet end of the faucet valve body 1; it also includes a temperature measuring device 3; the temperature measuring device 3 includes an installation shell 301, a sealing shell 302, a switch button 303, a temperature measuring frame 304, a clamping knob 305, a water retaining shell 306, an LCD display 307, a support rod 308, a clamping plate 309, a push-pull rod 310, a displacement cylinder 311, a programmable microcontroller 312, a USB charging interface 313, an infrared temperature sensor 314 and a battery pack 315; the right end of the support rod 308 is hinged to the left side of the clamping plate 309, and the left end of the support rod 308 is hinged to the inner side of the installation shell 301; the right end of the push-pull rod 310 is hinged to the left side of the clamping plate 309, and the left end of the push-pull rod 310 is hinged to the inner side of the installation shell 301 On the inner side, the push-pull rod 310 is hinged with the displacement cylinder 311; the clamping knob 305 is rotatably connected to the outer side of the displacement cylinder 311, and the bottom end of the clamping knob 305 is bonded with a water retaining shell 306; the T-shaped convex strip on the left side of the sealing shell 302, a programmable microcontroller 312 is installed inside the sealing shell 302, and the lower side of the sealing shell 302 is connected to the temperature measuring frame 304 by bolts, and an infrared temperature measuring sensor 314 is installed on the temperature measuring frame 304; the programmable microcontroller 312 is connected to the LCD display 307 by wires, the programmable microcontroller 312 is connected to the battery pack 315 by wires, the programmable microcontroller 312 is connected to the infrared temperature measuring sensor 314 by wires, and the programmable microcontroller 312 is connected to the switch button 303 by wires; the USB charging interface 313 is connected to the battery pack 315 by wires.

[0027] When installing the faucet temperature display instrument of the present invention, the installation shell 301 is first nested on the outer side of the water outlet pipe 2. At this time, the water outlet pipe 2 is located between the six groups of clamping plates 309 distributed in the circular array. One hand holds the outer side of the installation shell 301 to keep the installation shell 301 still, and the other hand pinches the rough texture structure of the clamping knob 305 and twists the clamping knob 305. Since the thread on the outer side of the clamping knob 305 and the thread structure on the inner side of the installation shell 301 are meshed with each other, the clamping knob 305 moves vertically downward along the thread rotation process, and the clamping knob 305 drives the displacement cylinder 311 connected to the inner side rotation to move downward synchronously. The six groups of support plate structures on the side surface of the displacement cylinder 311 respectively pull the six groups of push-pull rods 310 hingedly connected to each other to synchronously flip downward. The six groups of push-pull rods 310 push the six groups of clamping plates 309 hinged at the front end during the flipping process. The clamping plates 309 are supported by the pulling of the support rods 308 301, and then the faucet valve body 1 is opened, and the water flows out from the water outlet of the water pipe 2. The infrared temperature sensor 314 detects the high-temperature infrared radiation of the water flow in the water retaining shell 306. The infrared temperature sensor 314 detects the generated electrical signal and transmits it to the programmable microcontroller 312 for digital processing. Finally, the programmable microcontroller 312 transmits the data to the LCD display 307 for display, and the non-contact temperature measurement of the water flow by the faucet temperature display is completed.

[0028] In the disclosed embodiment, an annular groove is provided on the outer side surface of the displacement cylinder 311, and six groups of support plates are provided on the upper side surface of the displacement cylinder 311. The support plates are distributed in an annular array around the central axis of the displacement cylinder 311. The central part of the push-pull rod 310 is hinged to the top of the support plate of the displacement cylinder 311. The displacement cylinder 311 flips over by pulling the push-pull rod 310 through the support plate, so that the six groups of push-pull rods 310 respectively drive the six groups of clamping plates 309 to complete the clamping of the water outlet pipe 2.

[0029] In the disclosed embodiment, the clamping knob 305 is a cylindrical structure that passes through from top to bottom. The outer side surface of the clamping knob 305 is provided with a threaded structure and a rough texture structure from top to bottom. The rough texture on the outer side surface of the clamping knob 305 increases the hand contact friction, making it convenient for the clamping knob 305 to be rotated and tightened on the inner side of the mounting shell 301 through the threaded structure. A ring plate is provided on the inner side surface of the clamping knob 305, and the ring plate of the clamping knob 305 is embedded in the annular groove on the outer side surface of the displacement cylinder 311, so that the displacement cylinder 311 is pulled vertically up and down during the rotation of the clamping knob 305.

[0030] In the embodiment of the present disclosure, the mounting shell 301 is a cylindrical structure that passes through from top to bottom. The outer side surface of the mounting shell 301 is provided with a T-shaped groove with an upper opening. The T-shaped convex strip on the left side surface of the sealing shell 302 is inserted into the T-shaped groove of the mounting shell 301, so that after the sealing shell 302 and the mounting shell 301 are separated and disassembled, the battery pack 315 can be charged separately through the USB charging interface 313, and there is no need to frequently separate and disassemble the mounting shell 301 and the water outlet pipe 2. A threaded structure is provided on the inner side surface of the mounting shell 301, and the threaded structure on the outer side surface of the clamping knob 305 is meshed and connected to the threaded structure on the inner side surface of the mounting shell 301. The clamping knob 305 can move vertically up and down on the inner side of the mounting shell 301 through the threaded structure of the mounting shell 301.

[0031] In the disclosed embodiment, the water retaining shell 306 is made of transparent glass, and the bottom of the water retaining shell 306 is lower than the position of the infrared optical lens of the infrared temperature sensor 314 to prevent water from splashing onto the infrared temperature sensor 314 and avoid contact between the infrared temperature sensor 314 and the water.

[0032] In the disclosed embodiment, there are six groups of splints 309, and a rubber gasket is bonded to the contact surface between each group of splints 309 and the water outlet pipe 2. The rough structure on the surface of the rubber gasket increases the contact friction between the splints 309 and the outer surface of the water outlet pipe 2, making the splints 309 clamp the water outlet pipe 2 more stably and preventing the temperature measuring device 3 from slipping off the outer surface of the water outlet pipe 2.

[0033] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The LCD display 307, programmable microcontroller 312, USB charging interface 313, infrared temperature sensor 314 used above are all common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.

[0034] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
