Description

Technical Field

[0001] This utility model belongs to the field of heating system outlet water temperature display technology, and in particular relates to an outlet water temperature display and control device. Background Technology

[0002] Traditional faucets do not have electronic temperature displays, so users cannot intuitively know the current water temperature or monitor temperature changes in real time. Users often need to estimate the water temperature based on past experience. Some heating systems may have large temperature fluctuations during the heating process, resulting in the actual water temperature not matching the user's expectations. This is especially true when multiple people use the water continuously, as the water temperature may fluctuate, causing inconvenience. When the water temperature is too high, direct contact with hot water can easily cause scalding, especially for the elderly, children, or people with sensitive skin, who are at greater risk of scalding. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a water temperature display and control device, which solves the problem that traditional faucets are not equipped with electronic temperature display screens, and users rely solely on experience to estimate water temperature, which can easily lead to scalding. Moreover, it does not require manual opening and closing, and the display automatically turns off when there is no water flow, without consuming additional power.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a water temperature display and control device, including a faucet, comprising: a faucet for connecting to the water outlet pipe of a heating system and controlling water outlet; a control unit mounted on the faucet for sensing water flow to turn on and off the power supply and for detecting water temperature; a display for displaying the water temperature; and a battery electrically connected to the control unit and the display for providing power; when water is dispensed from the faucet, the control unit senses the water flow, turns on the power supply to the display, and displays the water temperature on the display.

[0006] Furthermore, the control unit includes a mounting base fixedly connected to the surface of the faucet, a temperature sensor is installed on one side of the bottom of the mounting base, the temperature sensor extends into the pipe of the faucet, a magnetic switch is installed inside the mounting base, and an opening and closing assembly is provided at the bottom of the mounting base, the opening and closing assembly being disposed inside the pipe of the faucet; the opening and closing assembly is used to sense water flow and trigger the magnetic switch.

[0007] To achieve the above technical solution, the battery is connected to a temperature sensor, a magnetic switch, and a display via a circuit. The opening and closing assembly is located inside the faucet. When water flows through, the opening and closing assembly is activated, controlling the magnetic switch to turn on the power to the display. The temperature sensor is used to detect the temperature of the water flow in the pipe. The temperature sensor converts the water temperature change into an electrical signal and transmits it to the display.

[0008] Furthermore, the opening and closing assembly includes a baffle plate, a magnet is fitted at the end of the baffle plate away from the mounting base, a rotating shaft is provided at the end of the baffle plate near the mounting base, a connecting block is provided at the bottom of the mounting base, and the rotating shaft is hinged to the connecting block; when the baffle plate is pushed upward by the water flow, it will flip upward, and the magnetic switch in the mounting base will connect the power supply of the display unit under the magnetic force of the magnet.

[0009] Furthermore, the magnetic switch is a reed switch or a Hall sensor.

[0010] To achieve the above technical solution, the baffle plate flips upward when pushed by the water flow, and controls the magnetic switch in the mounting base through the baffle plate to connect the display current; the movement of the magnet changes the magnetic field strength around the magnetic switch, and when the magnetic field strength changes, the generated Hall voltage is used to drive a switching element such as a transistor or relay, thereby completing the connection or disconnection of the circuit.

[0011] Furthermore, an elastic element for assisting the water baffle plate in resetting is provided between the bottom of the mounting base and the water baffle plate.

[0012] Furthermore, the elastic element is a spring or an elastic assembly, the elastic assembly including an arc-shaped telescopic rod connected to the bottom of the mounting base and the far end of the baffle plate, a spring sleeved on the outside of the arc-shaped telescopic rod, and a rubber sleeve wrapped around the outside of the return spring.

[0013] To achieve the above technical solution, when the water baffle is pushed by the water flow, it will push the arc-shaped telescopic rod to retract and push the return spring to squeeze. When the water stops flowing, the return spring will be used to spring the water baffle back to its original position.

[0014] Furthermore, the battery is also connected to a charging port for charging the battery.

[0015] To achieve the above technical solution, the battery is connected to the display via a circuit, and the battery receives charging from an external power source through a charging port; the display shows temperature information based on the received signal.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model features an opening and closing mechanism. Specifically, when water flows from the faucet, the water flow in the pipe pushes a baffle plate at the bottom of the mounting base, causing a magnet on the baffle plate to move along with it. When the magnet moves to the bottom of the mounting base, it controls a reed switch inside the mounting base to connect the current, and the water temperature is displayed on the screen. When there is no water flow, the baffle plate resets. Users can observe the real-time temperature display on the screen to determine if the water temperature is suitable for use, thus avoiding scalding. Furthermore, it does not require manual opening and closing and automatically shuts off when not in use, consuming no additional power.

[0018] 2. This utility model ensures the water baffle's reset effect by setting a reset spring or elastic component. At the same time, by setting a rubber sleeve, the water baffle moves and causes the arc-shaped telescopic rod to retract, while the reset spring is squeezed. The rubber sleeve protects the arc-shaped telescopic rod and the reset spring, preventing them from contacting the water flow and improving their service life. In addition, the rubber sleeve can expand and contract without affecting the movement of the arc-shaped telescopic rod and the reset spring.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Implementation Method 1

[0031] Please see Figure 1 , Figure 2 , Figure 5 As shown, the water temperature display and control device of this utility model includes a water outlet pipe for connecting to the heating system, a faucet 1 for controlling the water outlet, a control unit 2 fixedly mounted on the faucet, and a display 32 for displaying the water temperature; wherein, the control unit 2 and the display 32 are connected by a wire and electrically connected to a battery 31; when the faucet 1 dispenses water, the control unit 2 will turn on the current of the display 32 and display the water temperature on the display 3.

[0032] The control unit 2 includes a mounting base 21 installed on the faucet 1. The mounting base 21 is embedded in the faucet 1 and communicates with the internal pipe of the faucet. A temperature sensor 22 is installed on the bottom right side of the mounting base 21. The temperature sensor 22 extends into the pipe of the faucet 1 and is connected to the display 32 via a wire for detecting water temperature. A magnetic switch is installed inside the mounting base 21 and is connected to a battery via a wire. An opening and closing component 23 is also installed at the bottom of the mounting base 21. The opening and closing component 23 is installed inside the pipe of the faucet 1 and is used to sense water flow and trigger the magnetic switch, thereby activating the display power. Specifically, the opening / closing assembly 23 includes a baffle plate 231. A magnet 232 is mounted on the end of the baffle plate 231 away from the mounting base 21, and a rotating shaft 236 is provided on the end of the baffle plate 231 near the mounting base 21. A connecting block 237 is provided at the bottom of the mounting base 21, and the rotating shaft 236 and the connecting block 237 are hinged to each other. When the baffle plate 231 is pushed upward by the water flow, it will flip upward, and the magnet 232 will move accordingly. The magnetic field of the magnet will change the magnetic field strength around the magnetic switch, and the magnetic field will be used to connect the switching element. The switching element can be a reed switch, Hall sensor, etc., thereby connecting or disconnecting the power circuit of the display. The working principle of the magnetic switch is a well-known technology and will not be described in detail here. A cover plate 211 is also provided on the top of the mounting base 21 to close the mounting base. For easy installation and to allow the battery 31 to be charged by an external power source, a charging port 33 for charging the battery 31 is also provided on the housing. Users can observe the temperature display on monitor 32 to determine if the water temperature is suitable for use, thus avoiding scalding. The monitor automatically turns off when there is no water flow, eliminating the need for manual operation and consuming no additional power.

[0033] To assist the water baffle 231 in resetting and make the resetting more stable, a useful elastic element is also provided between the bottom of the mounting base 21 and the water baffle 231. In this embodiment, the elastic element is a spring 235.

[0034] Implementation Method 2

[0035] Please see Figure 1 , Figure 3-6As shown, this embodiment is basically the same as embodiment one, except that the elastic element is further optimized. The elastic element includes an arc-shaped telescopic rod 234 fixedly connected to the bottom of the mounting base 21 and the far end of the baffle plate 231, a spring 235 sleeved on the outside of the arc-shaped telescopic rod, and a rubber sleeve 233 wrapped around the outside of the spring 235. When the baffle plate 231 is pushed by the water flow, it will cause the baffle plate 231 to flip upward, which will push the arc-shaped telescopic rod 234 to retract and push the return spring 235 to squeeze. The baffle plate 231 controls the magnetic switch in the mounting base 21 to turn on the current, and the water temperature is displayed on the display 32. When there is no water flow, the spring 235 will use the baffle plate 231 to spring back to its original position. The rubber sleeve 233 protects the arc-shaped telescopic rod 234 and the return spring 235, preventing them from contacting the water flow and improving their service life. At the same time, the rubber sleeve 233 can extend and retract without affecting the movement of the arc-shaped telescopic rod 234 and the return spring 235.

[0036] One specific application of this embodiment is:

[0037] In use, install faucet 1 on the water outlet pipe of the water heater, and fix the external brackets of display 32 and battery 31 in a waterproof position. When faucet 1 is used, the water flow will push the baffle 231. At this time, the top of the baffle 231 rotates on the connecting block 237 via the pivot 236. When the baffle 231 moves, it will cause the arc-shaped telescopic rod 234 to retract, and the spring 235 will be compressed. The rubber sleeve 233 protects the arc-shaped telescopic rod 234 and the return spring 235, preventing them from contacting the water flow and improving their service life. The magnet 232 on the baffle 231 moves along with it. The magnet 232 cooperates with the magnetic switch 238 in the mounting base 21 to turn on the power to the battery 31 and display 32, so that the current is transmitted to Display 32; Temperature sensor 22 is a thermistor or RTD (resistance temperature detector). The temperature sensor 22 changes its resistance value according to the water temperature change. This change is converted into an electrical signal and sent to display 32. After proper calibration and processing, the water temperature is displayed in digital form. At this time, the user can observe the temperature display on display 32 to determine whether the water temperature is suitable for use, thus avoiding scalding. When the faucet 1 is closed and the water flow stops, the baffle 231 will be reset by the elastic action of the return spring 235. Then the magnet 232 will move away from the magnetic switch 238. At this time, the magnetic switch 238 in the mounting base 21 is de-energized. This method does not require manual opening and closing and automatically closes when there is no water flow, without consuming additional power.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
