Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically a faucet that facilitates water temperature adjustment. Background Technology

[0002] The faucets used in the kitchen and bathroom are all equipped with adjustable hot and cold water functions. Switching between hot and cold water is as simple as turning the faucet. The switching method is simple and effortless, making it convenient for our daily use.

[0003] To reduce the discomfort caused by the sudden temperature change between hot and cold water, some bathroom faucets are equipped with protective devices during this transition, facilitating temperature adjustment. A search revealed a faucet in patent application CN1621720A, specifically a water heater temperature-adjustable faucet. Its key feature is a water flow regulating device between the inlet and outlet. This device is continuously adjustable. It consists of a fixed water-blocking plate within the faucet body and an adjustable water-blocking plate within the same body. Each water-blocking plate has an opening, and the two plates overlap. Adjusting the adjustable plate changes the area of ​​the overlapping opening. This water heater temperature-adjustable faucet allows for convenient temperature adjustment during showering.

[0004] The device uses two water-blocking plates, and the water temperature is adjusted by changing the size of the opening between the two water-blocking plates. However, since the temperature sensing element is located inside the faucet, there is a large temperature difference between the water flowing out from the outside and the water temperature sensed by the temperature sensing element when the faucet switches between hot and cold water. There is a delay in water temperature adjustment. When manually adjusting based on skin feedback, discomfort can easily occur due to the temperature difference, and water resources will be wasted during adjustment. Utility Model Content

[0005] The purpose of this utility model is to provide a faucet that facilitates water temperature adjustment. By setting a temperature sensor at the water outlet of the faucet, the temperature of the flowing water is sensed. Water at an unsuitable temperature is stored by changing the direction of water flow through a switching structure, thus saving water resources. Water at a suitable temperature flows out normally from the faucet outlet for user use, avoiding the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a faucet for convenient water temperature adjustment, including a base, a faucet valve body and a control panel fixed on one side of the base, a faucet switch for controlling the water flow size rotatably connected to one end of the faucet valve body, and a water outlet pipe connected to the other end of the faucet valve body, wherein a temperature sensing control structure is provided at the water outlet end of the water outlet pipe.

[0007] The temperature sensing control structure includes a connector, the top of which is threaded to the outer wall of the outlet pipe. A temperature sensor is fixed inside the connector. A switching structure capable of changing the water flow path is provided at the bottom of the connector. A drive structure for driving the switching structure to rotate is rotatably connected to the outer wall of the connector. Both the temperature sensor and the drive structure are electrically connected to the control panel.

[0008] Preferably, the switching structure includes a water inlet pipe, one end of which is fixedly connected to a rubber tube, and the other end of which is glued to an inlet pipe for supplying water at an unsuitable temperature.

[0009] Preferably, the drive structure includes a drive motor, a connecting ring is threaded onto the outer wall of the connector, a fixing block is welded to one end of the connecting ring, the drive motor is fixed to the top of the fixing block by screws, and a transmission structure is provided at the output end of the drive motor.

[0010] Preferably, the transmission structure includes a first gear and a second gear, a rotating rod is rotatably connected to the bottom of the fixed block, the first gear is fixedly connected to the output end of the drive motor through a rotating shaft, the second gear is fixed to the outer wall of the rotating rod, and the first gear meshes with the second gear.

[0011] Preferably, the rotating rod is L-shaped, and one end of the horizontal rotating rod is fixedly connected to the outer wall of the water inlet pipe.

[0012] Preferably, the connector includes a first connecting part and a second connecting part. The first connecting part is threaded to the outer wall of the water outlet pipe, and a crossbar is fixed in the inner cavity of the second connecting part. The temperature sensor is fixed in the middle of the crossbar.

[0013] Preferably, the water inlet pipe is located on one side of the water outlet pipe, and the water inlet pipe is tied to the outer wall of the water outlet pipe by cable ties.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by placing the temperature sensor inside the outlet connector, can monitor the actual temperature data of the flowing water, avoiding the temperature sensing lag problem caused by the rearward position of the sensor in traditional designs. With a preset temperature value, the device allows users to determine whether the water temperature is suitable simply by observing whether the inlet pipe has been moved away from the outlet pipe after turning on the faucet, without needing to manually measure the temperature. This avoids the risk of users coming into contact with unsuitable water temperatures.

[0016] 2. By setting an L-shaped rotating rod switching structure, the water flow path is switched through gear transmission. When water is discharged, if the temperature sensor detects that the water temperature exceeds the set threshold, the main control board in the control panel drives the motor to rotate and move the water into the inlet pipe, allowing water at an unsuitable temperature to enter the inlet pipe; when the water temperature is detected to be suitable, the water flows out normally, and one end of the inlet pipe can be connected to a water storage tank for storage, so that the recycled water can be conveniently used for flushing toilets, irrigation, and other scenarios, improving the household water recycling rate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a faucet that is convenient for adjusting water temperature, including a base 1, a faucet valve body 2 and a control panel 3 fixed on one side of the base 1, a faucet switch 4 for controlling the water flow size rotatably connected to one end of the faucet valve body 2, and a water outlet pipe 5 connected to the other end of the faucet valve body 2, with a temperature sensing control structure 6 provided at the water outlet end of the water outlet pipe 5.

[0024] The temperature sensor 602 is a DS18B20-PAR model, fixed in the middle of the crossbar 6013 of the connector 601 at the outlet end, directly contacting the water flow. The data is transmitted to the main control board of the control panel 3 via RS485 bus. The main control board has a built-in PID algorithm that compares the real-time temperature with the preset threshold. When the water temperature is detected to be outside the safe range, i.e., T>40℃ or T<36℃, the drive motor 6041 is triggered.

[0025] The temperature sensing control structure 6 includes a connector 601, the top of which is threaded to the outer wall of the water outlet pipe 5. A temperature sensor 602 is fixed inside the connector 601. A switching structure 603 capable of changing the water flow path is provided at the bottom of the connector 601. A driving structure 604 that drives the switching structure 603 to rotate is rotatably connected to the outer wall of the connector 601. Both the temperature sensor 602 and the driving structure 604 are electrically connected to the control panel 3.

[0026] The switching structure 603 includes a water inlet pipe 6031, one end of which is fixedly connected to a rubber tube 6032, and one end of the rubber tube 6032 is glued to an inlet pipe 6033 for supplying water at an unsuitable temperature.

[0027] By setting the rubber tube 6032, when switching the water flow direction, the offset of the inlet pipe 6033 allows the rubber tube 6032 to deform and move to the right.

[0028] The drive structure 604 includes a drive motor 6041. A connecting ring 6042 is threaded onto the outer wall of the connector 601. A fixing block 6043 is welded to one end of the connecting ring 6042. The drive motor 6041 is fixed to the top of the fixing block 6043 by screws. A transmission structure is provided at the output end of the drive motor 6041.

[0029] The transmission structure includes a first gear 6044 and a second gear 6045. A rotating rod 6046 is rotatably connected to the bottom of the fixed block 6043. The first gear 6044 is fixedly connected to the output end of the drive motor 6041 through a rotating shaft. The second gear 6045 is fixed to the outer wall of the rotating rod 6046. The first gear 6044 and the second gear 6045 mesh.

[0030] After the drive motor 6041 is started, the first gear 6044 drives the second gear 6045 to rotate, causing the rotating rod 6046 to rotate. The rotating rod 6046 causes the water inlet pipe 6033 to shift. When the water inlet pipe 6033 is below the water outlet pipe 5, it is used to transfer water to the water inlet pipe 6033.

[0031] The rotating rod 6046 is L-shaped, and one end of the horizontal rod of the rotating rod 6046 is fixedly connected to the outer wall of the water inlet pipe 6033.

[0032] The connector 601 includes a first connecting part 6011 and a second connecting part 6012. The first connecting part 6011 is threaded to the outer wall of the water outlet pipe 5. A crossbar 6013 is fixed in the inner cavity of the second connecting part 6012. The temperature sensor 602 is fixed in the middle of the crossbar 6013.

[0033] The first connecting part 6011 is used to connect the connector 601 to the water outlet pipe 5, and the second connecting part 6012 is used to install the temperature sensor 602.

[0034] The water inlet pipe 6031 is located on one side of the water outlet pipe 5, and the water inlet pipe 6031 is tied to the outer wall of the water outlet pipe 5 by cable ties. The cable ties are used to secure the water inlet pipe 6031 to the outer wall of the water outlet pipe 5.

[0035] When in use, when water is started to flow, if the temperature sensor 602 detects that the water temperature exceeds the set threshold, it sends a PWM signal through the main control board in the control panel 3 to drive the motor 6041 to rotate forward. The first gear 6044 drives the second gear 6045 to rotate, causing the rotating rod 6046 to rotate. The rotating rod 6046 drives the inlet pipe 6033 to shift below the outlet pipe 5, so that the opening of the rubber tube 6032 is aligned with the main outlet channel, and water at an unsuitable temperature enters the inlet pipe 6033. When the water temperature is detected to be suitable, the water flows out normally.

[0036] The device uses a preset temperature value. After the user turns on the faucet switch 4, there is no need to manually measure the temperature. The user can determine whether the water temperature is suitable simply by checking whether the inlet pipe 6033 is moved away from the outlet pipe 5. This avoids the risk of the user coming into contact with water of unsuitable temperature. One end of the inlet pipe 6033 can be connected to a water storage tank for storage, so that the recycled water can be conveniently used for flushing toilets, watering, and other scenarios, thereby improving the recycling rate of household water.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
