In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0063] The following is combined Figure 25 and Figure 26 This invention describes a control method for a water supply system according to an embodiment of the invention. The entity executing this method can be a controller within the water supply system, or a cloud-based system, or an edge server.

[0064] Water purifiers and faucets constitute a water supply system. Water purifiers are water treatment devices that filter, purify, and heat water according to the user's water usage requirements.

[0065] The water purifier's inlet is connected to an external water supply network, and the water purifier's outlet 111 is connected to the faucet's inlet. After processing the water from the external water supply network, the water purifier delivers the water to the faucet, and water flows out of the faucet's outlet 111 for the user to use.

[0066] The water supply system is equipped with solenoid valves, which are automated components used to control fluids and can adjust the direction, flow rate, speed and other parameters of water in the inlet and outlet pipes.

[0067] In the water supply system, a solenoid valve is installed between the water outlet 111 of the water purifier and the water outlet 111 of the faucet. By controlling the opening and closing of the solenoid valve, the water flow from the faucet outlet 111 can be started and stopped.

[0068] In practice, the solenoid valve can be installed inside the water purifier or inside the faucet, and can be used to control the start and stop of water flow from the faucet outlet 111.

[0069] A solenoid valve is installed between the water outlet 111 of the water purifier and the water outlet 111 of the faucet, eliminating the mechanical valve built into the faucet in related technologies, and the water supply system is electrically controlled by the solenoid valve.

[0070] like Figure 25 As shown, the control method for the water supply system includes steps 2510 to 2520.

[0071] Step 2510: Receive the first input from the user to turn the faucet handle in the first direction.

[0072] When the faucet is in a water-off state, the user operates the handle on the faucet to turn in the first direction and to the first target position. The first sensor 430 in the handle generates a corresponding electronic control signal, and the water supply system receives the first input.

[0073] The first input is the control command input by turning the faucet handle. The first input can control the start and stop of water flow, water temperature and water flow in the water supply system.

[0074] When the handle is rotated to the first target position in the first direction, the elastic force generated by the elastic element 360 in the handle causes the handle to return to the initial position. This eliminates the need for the user to reset the handle, overcoming the defect in related technologies where the user needs to reset the handle after it is rotated, and simplifying the process of taking water from the faucet.

[0075] In practice, taking the faucet located in front of the user as an example, the first direction can be the direction in which the user operates the handle backward, that is, away from the user; the first direction can also be the direction in which the user operates the handle forward, that is, closer to the user.

[0076] Step 2520: In response to the first input, control the water purifier to produce water and open the solenoid valve so that water flows out of the faucet outlet 111.

[0077] In this embodiment, the action of controlling the water tap to start and stop in response to the first input is used. The first input is a control command in the water supply system. In some embodiments, the first input can also be a control command to control the water temperature or the water flow rate.

[0078] The water supply system responds to the first input by controlling the solenoid valve to open and the faucet to dispense water for the user.

[0079] In this embodiment, in response to the first input, the water purifier is controlled to start producing water. The water purification process of the water purifier mainly involves purifying the water from the water supply network, including removing solid impurities, dechlorinating, and removing metal particles.

[0080] The water production mode of a water purifier is the mode that the user sets on the water supply system to adjust the outlet water temperature, outlet water quality, water purification level, and other water treatment standards before the first input is received from the handle.

[0081] In this embodiment, upon receiving the first input from the handle, the water purifier starts producing water according to the pre-set water production mode in response to the first input. At the same time as the water purifier produces water, the solenoid valve is opened, connecting the leaching water pipeline between the faucet and the water purifier. The water produced by the water purifier flows out from the faucet outlet 111 for the user to use.

[0082] According to the control method of the water supply system provided in the embodiment of the present invention, the water flow of the faucet is controlled by rotating the handle in the first direction. After the handle is rotated, it can be automatically reset by the elastic element 360, so that the user does not need to reset the handle. The water intake process is more convenient and faster. Furthermore, a solenoid valve is set in the water supply system to control the water flow, thereby realizing the intelligent control of the water supply system.

[0083] In some embodiments, after receiving the first input, it is also necessary to make a further judgment on whether to control the solenoid valve to open based on the water production mode currently set by the water supply system.

[0084] The target temperature is the set safe water temperature, and also a water temperature limit to prevent scalding. Water below the target temperature will not cause scalding when used by the user; water above the target temperature may cause scalding when used by the user. The target temperature can be 45 degrees Celsius, 50 degrees Celsius, or can be set by the user according to their needs.

[0085] In practice, the target temperature can be 45 degrees Celsius, 50 degrees Celsius, or set by the user according to their needs.

[0086] For example, let's take the user's current water production mode as producing hot water at 80 degrees Celsius.

[0087] The set outlet water temperature of 80 degrees Celsius is higher than the target temperature of 45 degrees Celsius. After the user turns the handle in the first direction to the first target position, it is necessary to determine whether to control the solenoid valve to open based on the dwell time of the first input.

[0088] Using the first target duration as the criterion for judging the duration of water discharge from outlet 111, the first input is divided into two categories: the first input where the handle stays at the first target position for no more than the first target duration, and the first input where the handle stays for a longer than the first target duration.

[0089] In practice, a short turn is defined as the operation where the user rotates the handle in the first direction to the first target position and holds it for no more than the first target duration; a long turn is defined as the operation where the handle holds for more than the first target duration.

[0090] It is understandable that the first input received will be different depending on the time the handle stays after being turned to the first target position in the first direction. Based on the different first inputs and the difference between the current water temperature set by the faucet and the target temperature, it is determined whether to control the water outlet 111 of the faucet to dispense water.

[0091] If the current set water temperature is higher than the target temperature, turn the handle in the first direction to the first target position, and keep it in the first target position for a shorter time than the first target time. This will close the solenoid valve, and the water outlet 111 of the faucet will not flow out. Water with a temperature higher than the target temperature will not flow out directly to avoid scalding the user.

[0092] In other words, if the current set water temperature is higher than the target temperature, the user cannot control the solenoid valve to open by briefly turning the handle, and water will flow from the faucet outlet 111, which can effectively prevent the user from being scalded.

[0093] For example, if the first user sets the water temperature to 90 degrees Celsius for cooking, and the second user wants to wash their hands, the second user briefly pulls the handle. At this time, the water cannot be controlled from the faucet outlet 111, thus preventing the second user from being scalded by the 90-degree Celsius hot water.

[0094] In actual use, the current set water temperature can be displayed on the faucet's display screen 450, and the user can be prompted to turn the handle for a long time to release water.

[0095] In some embodiments, when the user-set water temperature is not higher than the target temperature, the user operates the handle for a shorter time at the first target position than the first target duration, thereby controlling the solenoid valve to open and the faucet to dispense water.

[0096] The user sets the water temperature to be no higher than the target temperature. The handle is turned in the first direction to the first target position, and the time held in the first target position is shorter than the first target time. The solenoid valve is opened, and water flows out of the faucet outlet 111. At this time, the water temperature flowing out of the faucet is below the target temperature and can flow out directly without scalding the user.

[0097] In other words, if the current water temperature set by the faucet is not higher than the target temperature, the user can control the water outlet 111 to flow by briefly turning the handle, and the handle can be automatically reset by the elastic element 360 degrees, without the need for the user to manually reset it, thus simplifying the water dispensing process.

[0098] In some embodiments, the user sets the outlet water temperature to be higher than the target temperature, and the user operates the handle at the first target position for a duration not less than the first target duration, controlling the water purifier to produce water according to the current water production mode, and controlling the solenoid valve to open so that water can be dispensed from the faucet for the user's use.

[0099] For example, users can set the water temperature to 90 degrees Celsius for cooking. After setting, they can simply pull the handle to control the water flow for the user.

[0100] The first input, which holds the handle at the first target position for a duration not less than the duration of the first target, is the input command that directly controls the water flow from the faucet.

[0101] By using the long lever, users can control the solenoid valve to start dispensing water from the faucet outlet 111 when the water temperature is different. This saves the time of adjusting the temperature when dispensing water, and the lever can automatically reset via the elastic element 360 degrees, eliminating the need for manual reset.

[0102] In some embodiments, if the current water temperature of the faucet is higher than the target temperature, and the handle is held in the first target position for a shorter time than the first target time, the water outlet 111 of the faucet is controlled to stop the water flow, so that water with a temperature higher than the target temperature will not flow out directly, and a reminder message is displayed on the display screen 450 of the faucet.

[0103] The display screen 450 can show reminder information that may include the current water temperature of the faucet and a prompt to control the water flow by extending the handle.

[0104] Users can adjust the temperature according to the prompts on the display screen 450, and then briefly turn the handle to control the water flow from the faucet outlet 111, or they can turn the handle long to control the water flow from the faucet.

[0105] In some embodiments, if the current water temperature of the faucet is higher than the target temperature, and the handle is held in the first target position for a shorter time than the first target time, the water outlet 111 of the faucet is controlled to stop the water flow, water with a temperature higher than the target temperature will not flow out directly, and the breathing light 460 of the faucet is controlled to flash in the target manner.

[0106] The faucet's breathing light 460 flashes in a target manner to remind the user that the current water temperature is higher than the target temperature, which may cause scalding.

[0107] In this embodiment of the invention, the breathing light 460 flashes in a targeted manner to provide a more convenient and faster reminder, allowing users to receive a danger warning without having to check the current water temperature coming out of the faucet.

[0108] In actual implementation, the faucet's breathing light 460 flashes in a targeted manner, whereby the targeted manner can be manifested in at least one of the following ways: target flashing color, target flashing interval, and target flashing brightness, etc.

[0109] Firstly, the faucet's breathing light 460 flashes with a target flashing color, which includes, but is not limited to, red, yellow, and green.

[0110] In this embodiment, if the current water temperature from the faucet is higher than the target temperature, and the handle is held in the first target position for a shorter time than the first target time, the water outlet 111 of the faucet is shut off, and the breathing light 460 of the faucet is controlled to flash in the target flashing color to remind the user that the current water temperature from the faucet is higher than the target temperature, which may cause scalding.

[0111] Secondly, the breathing light on the faucet flashes at 460-degree intervals.

[0112] In this embodiment, the water outlet 111 of the faucet is shut off, and the breathing light 460 of the faucet is controlled to flash at a frequency of 4 times per second to remind the user.

[0113] Thirdly, the breathing light of the faucet flashes at a target brightness of 460 degrees.

[0114] In this embodiment, the faucet's breathing light 460 flashes at a low brightness in standby mode. When the current water temperature is higher than the target temperature, the handle is held in the first target position for a shorter time than the first target duration, and the water outlet 111 is shut off, the faucet's breathing light 460 flashes at a higher brightness to remind the user.

[0115] Of course, in other embodiments, the target flashing mode of the breathing light 460 may also be in other forms, which can be determined according to actual needs. This application embodiment does not limit this.

[0116] In some embodiments, when the operating handle is turned in a second direction, the water supply system receives a second input from the handle and controls the outlet water temperature.

[0117] The handle on the faucet can be turned in different directions. Turning the handle in the first direction will reach the first target position, and turning it in the second direction will reach the second target position.

[0118] It is understandable that after the handle is rotated to the first target position in the first direction, and then rotated to the second target position in the second direction, it can be reset by the elastic force of the elastic element 360 in the handle.

[0119] When the handle is turned to the first target position in the first direction and to the second target position in the second direction, the first sensor 430 on the handle will generate different electronic control signals. The corresponding first and second inputs are instructions that can control the water supply system's start and stop, water temperature, and water flow.

[0120] For example, turning the handle in the first direction to the first target position corresponds to the first input used to control the water flow of the faucet; turning the handle in the second direction to the second target position corresponds to the second input used to control the water temperature of the faucet.

[0121] In practice, taking the faucet located in front of the user as an example, the first direction can be the direction in which the user operates the handle backward, that is, away from the user. At this time, the second direction can be the direction in which the user operates the handle forward, that is, closer to the user.

[0122] In some embodiments, after receiving the second input from the handle, the water temperature needs to be adjusted differently depending on the duration the handle remains at the second target position.

[0123] Understandably, the water supply system is equipped with a corresponding temperature module, which can heat or cool the water flowing out of outlet 111 according to the adjusted outlet temperature setting, so that the water temperature flowing out of outlet 111 is consistent with the adjusted outlet temperature setting.

[0124] In response to the second input, the water temperature setting of the faucet can be adjusted continuously or once.

[0125] Continuous adjustment refers to the continuous and uninterrupted adjustment process of the outlet water temperature setting, such as from setting one to setting two, from setting two to setting three, and so on, until the input ends.

[0126] Single adjustment refers to a single adjustment of the water flow rate. Each adjustment is made up to one water temperature level. For example, the water temperature level is adjusted from level one to level two, and then the adjustment is complete.

[0127] Taking the current water temperature setting as 20 degrees Celsius and the temperature setting adjusted each time as 10 degrees Celsius as an example.

[0128] Continuous adjustment refers to adjusting the outlet water temperature setting from 20 degrees Celsius to 30 degrees Celsius, then from 30 degrees Celsius to 40 degrees Celsius, and so on, until the input is finished; single adjustment refers to adjusting the outlet water temperature setting from 20 degrees Celsius to 30 degrees Celsius, and then the adjustment is finished.

[0129] In this embodiment, the adjustment of the water temperature setting can be set to a cyclic mode. For example, the water temperature range is 45 degrees Celsius to 95 degrees Celsius, and the temperature setting is adjusted by 10 degrees Celsius each time. The adjusted water temperature settings are 45 degrees Celsius, 55 degrees Celsius, 65 degrees Celsius, 75 degrees Celsius, 85 degrees Celsius and 95 degrees Celsius.

[0130] Understandably, the temperature setting can be adjusted by the user according to their needs. For example, the temperature setting can be set to 5 degrees Celsius or 10 degrees Celsius each time.

[0131] Furthermore, the water temperature setting can be adjusted by increasing the water temperature from the faucet or decreasing it.

[0132] The second target duration is the criterion for determining whether to continuously adjust or adjust the water temperature once. If the handle is held in the second target position for a shorter time than the second target duration, the water temperature of the faucet will be adjusted once, and the currently set water temperature level can be displayed on the display screen 450.

[0133] Taking the current water temperature setting as 20 degrees Celsius and the temperature setting adjusted each time as 10 degrees Celsius as an example.

[0134] The user operates the handle to turn in the second direction to reach the second target position and hold it. The holding time is shorter than the second target time. This allows for a single adjustment of the water temperature setting, increasing the water temperature setting by 10 degrees Celsius. At this time, the display screen 450 shows the water temperature setting as 30 degrees Celsius.

[0135] In this embodiment, the water temperature setting can also be lowered by 10 degrees Celsius, at which point the display screen 450 will show a water temperature setting of 10 degrees Celsius.

[0136] In practice, a short turn is defined as the operation where the user rotates the handle in the second direction to the second target position and holds it for no more than the second target duration; a long turn is defined as the operation where the handle holds for more than the second target duration.

[0137] In some embodiments, when the handle is in the second target position for a duration not less than the second target duration, the water temperature of the faucet is continuously adjusted.

[0138] In this embodiment, the duration of the handle in the second target position is not less than the second target duration. The calculation is based on the time exceeding the second target duration. The water temperature is adjusted step by step based on the first target time interval until the handle leaves the second target position.

[0139] The first target time interval is the time standard for continuous adjustment of the water temperature setting. During the time when the handle is in the second target position for longer than the second target time, the water temperature setting is adjusted by one level every time the first target time interval has elapsed. When the handle leaves the target position, the adjustment of the water temperature setting stops.

[0140] Understandably, the first target time interval, the second target duration, and the temperature setting adjusted each time can all be set according to requirements.

[0141] Taking a target duration of 3 seconds and a target time interval of 1 second as an example.

[0142] The current water temperature setting is 20 degrees Celsius. If the handle remains at the second target position for more than 3 seconds, the water temperature setting will be adjusted step by step. At the 4th second, the water temperature setting will be adjusted to 30 degrees Celsius. At the 5th second, it will be adjusted up one level to 40 degrees Celsius. The adjustment will stop when the handle leaves the second target position.

[0143] Understandably, the process of adjusting the water temperature setting can be displayed on the screen 450. Users can adjust the current water temperature setting based on the display screen 450, and decide whether to stop the continuous adjustment of the water temperature setting.

[0144] It is worth noting that turning and holding the handle in the second direction is used to control the water temperature setting of the faucet. After setting the water temperature setting, the user needs to turn and hold the handle in the first direction again to control the water purifier to produce water and open the solenoid valve so that water at the set temperature flows out of the faucet.

[0145] In some embodiments, the faucet is currently in standby mode and receives a temperature display input from the user turning the handle in a second direction. In response to the temperature display input, the current water temperature setting is displayed on the faucet display screen 450.

[0146] In this embodiment, the faucet is currently in standby mode. At this time, the user's first rotation of the handle in the second direction is an input command used to display the current water temperature setting.

[0147] In response to the temperature display input, the current water temperature setting is displayed on the faucet display screen 450. Users can determine whether to take water or adjust the water temperature setting based on the current water temperature setting displayed on the faucet display screen 450 before taking water.

[0148] Understandably, after receiving the temperature display input from the user turning the handle in the second direction, the user turns the handle in the second direction again, and at this time, the second input is received to adjust the water temperature setting.

[0149] In practice, the current water temperature setting can be either the lowest water temperature setting or the water temperature setting set when the faucet was previously turned off.

[0150] The lowest water temperature setting can be adjusted according to the user's water usage environment or ambient temperature.

[0151] For example, in a kitchen water environment, where users mainly use water for washing vegetables or cooking, the lowest setting can be set to 20 degrees Celsius. After checking the water temperature setting on the display screen, users can easily take water for use directly.

[0152] In bathroom water environments, users mainly use water for showering or washing hands. In this case, the lowest setting can be set to 40 degrees Celsius. After checking the water temperature setting on the display screen, users can directly take water for use, saving time in adjusting the water temperature and making the water taking process more convenient.

[0153] When the ambient temperature is low, the lowest water temperature setting can be appropriately increased to save time adjusting the water temperature, and users can directly draw water for use.

[0154] The current water temperature setting can be the water temperature setting when the faucet was last turned off. For example, if the user set the water temperature setting to 50 degrees Celsius when the faucet was last turned off, the set water temperature setting can remain unchanged after the user stops using it. When the user turns the faucet back on, the temperature display will receive the temperature input and show that the current water temperature setting is 50 degrees Celsius, so that the user can directly take water and continue using it.

[0155] In some embodiments, a third input from the user to the first sensor 440 on the handle is received, and the water flow rate of the faucet is adjusted in response to the third input.

[0156] The first sensor 440 can be a light-sensitive button, which collects the user's pressing intention through light sensing signals and receives the user's third input to the first sensor 440.

[0157] The third input from the user to the first sensor 440 can take the form of the user lightly touching the first sensor 440, the first sensor 440 collecting the user's operating intention, generating a corresponding electronic control signal, and sending it to the faucet controller.

[0158] Among them, the first sensor 440 is a sensor that can operate without obstacles in a water environment. The user only needs to lightly touch the first sensor 440 to make the water supply system receive the third input, and the operation process will not cause the faucet to shake significantly.

[0159] Understandably, the water flow rate of a faucet can be controlled by opening and closing a solenoid valve. In practice, the volumetric flow rate can be calculated based on the current flow rate, and the timing of opening and closing of the electrically controlled valve in the water outlet pipeline can be controlled to achieve a quantitative water flow from the faucet.

[0160] In response to the third input, the water flow rate of the faucet can be adjusted continuously or once.

[0161] Among them, continuous adjustment refers to the continuous and uninterrupted adjustment process of the water output level, such as from level one to level two, from level two to level three, and so on, until the input ends.

[0162] Single adjustment refers to a single adjustment of the water flow rate. Each adjustment is made by inputting one water flow rate level. For example, the water flow rate is adjusted from level one to level two, and then the adjustment is completed.

[0163] Taking the current set water output of 500 ml as an example, and the quantitative setting adjusted each time as 200 ml.

[0164] Continuous adjustment refers to adjusting the water output level from 500 ml to 700 ml, then from 700 ml to 900 ml, and so on, until the input ends; single adjustment refers to adjusting the water output level from 500 ml to 700 ml, and then the adjustment ends.

[0165] In some embodiments, after receiving the third input, the water flow rate of the faucet can be continuously adjusted or adjusted once based on the duration of the third input.

[0166] The third target duration is the criterion for judging whether the water flow rate of the faucet can be adjusted continuously or once. When the duration of the third input is shorter than the third target duration, the water flow rate of the faucet is adjusted once, and the currently set water flow rate is displayed on the display screen 450.

[0167] Taking the current set water output of 500 ml as an example, and the quantitative setting adjusted each time as 200 ml.

[0168] If the duration of the third input of the user's first sensor 440 is shorter than the third target duration, the water output level will be adjusted once, increasing the water output by 200 ml. At this time, the display screen 450 will show that the water output level is 700 ml.

[0169] In practice, the quantitative level of the water output can be set by the user according to their needs. For example, the quantitative level can be set to 200, 500, 700 and 100 ml each time.

[0170] Understandably, adjusting the water flow level can either increase the water flow from the faucet by raising it or decrease it by lowering it.

[0171] In practice, a third input where the user's dwell time on the first sensor 440 does not exceed the third target duration is called a brief touch; a third input where the user's dwell time on the first sensor 440 exceeds the third target duration is called a continuous touch.

[0172] In other words, when a user briefly touches the first sensor 440, the water output level of the water supply system can be adjusted once, thereby achieving quantitative water output control.

[0173] In some embodiments, when the duration of the third input to the first sensor 440 is not less than the third target duration, the water flow rate of the faucet is continuously adjusted.

[0174] When the duration of the third input exceeds the third target duration, the water flow level of the faucet is adjusted step by step based on the second target time interval until the user stops inputting and the adjustment ends.

[0175] The second target time interval is the time standard for adjusting each level during the continuous adjustment of the water output level. During the period when the duration of the third input from the user to the first sensor 440 exceeds the third target time interval, the water output is adjusted by one level each time interval is elapsed until the third input is no longer received.

[0176] In practice, the time interval for the second target, the duration of the third target, and the quantitative level for each adjustment can all be set according to requirements.

[0177] Taking the third target duration as 3 seconds and the second target interval as 1 second as an example.

[0178] The current water flow rate is 500 ml. After the third input lasts for more than 3 seconds, the water flow rate of the faucet will start to adjust continuously in stages. At the 4th second, the water flow rate will be adjusted to 700 ml. At the 5th second, it will be adjusted up one level to 900 ml. The adjustment will stop when the third input is no longer received.

[0179] By setting the third target duration and the second target time interval, the water flow rate of the faucet can be continuously adjusted step by step according to the user's continuous input to the first sensor 440.

[0180] Understandably, the process of adjusting the water flow will be displayed on the screen 450. Users can adjust the water flow according to the current water flow level displayed on the screen 450 and decide whether to stop inputting the third input.

[0181] It is worth noting that the third input of the user to the first sensor 440 is used to control the water output of the faucet outlet 111. After setting the water output level, the user needs to operate the handle again to turn and hold in the first direction to control the water purifier to produce water and open the solenoid valve so that the faucet can output a fixed amount of water.

[0182] In some embodiments, the water flow rate of the faucet can also be adjusted by adjusting the water flow rate information displayed on the display screen 450.

[0183] The display screen 450 can display the current water flow rate setting, and users can adjust the water flow rate setting on the display screen 450 via touch operation.

[0184] Among them, adjusting the water output level on the display screen 450 can be performed as a single touch input, including but not limited to click input, swipe input, and press input.

[0185] In this embodiment, receiving user input on the display screen 450 to adjust the water flow rate once or continuously can be manifested as receiving touch operation from the user on the display area of ​​the display screen 450.

[0186] To reduce the rate of user error, the touch operation area can be limited to a specific area, such as the lower middle area of ​​the faucet display screen 450; or a target control can be displayed on the interface of the display screen 450, and the water flow level can be adjusted by touching the target control.

[0187] For example, a user can briefly touch the target control on the display screen 450 to adjust the water flow level, thus achieving a single adjustment of the water flow level; or, a user can briefly touch the upper center of the display screen 450 to increase the water flow level by one level, and briefly touch the lower center of the display screen 450 to decrease the water flow level by one level.

[0188] For example, a user can continuously touch the target control on the display screen 450 to adjust the water flow level step by step; or, a user can continuously touch the upper center of the display screen 450 to control the water flow level to be increased by multiple levels, and after each second target time interval, it will continue to be increased by one level until no more input is received to the display screen 450.

[0189] It is worth noting that after setting the water flow rate, the user needs to turn the handle in the first direction to control the water flow from the faucet outlet 111.

[0190] In some embodiments, when the faucet is currently in the water-discharging state, a fourth input from the user to turn the handle in the first direction is received, which controls the solenoid valve to close and the water outlet 111 of the faucet to stop the water flow.

[0191] In this embodiment, the faucet is currently in the water-discharging state. At this time, the user turns the second input of the handle in the first direction to control the water outlet 111 of the faucet to stop the water flow, and the faucet enters the standby state.

[0192] Understandably, the fourth input is a control command that changes the current on / off state of the solenoid valve. Whether the faucet is dispensing water in a metered or continuous manner, the fourth input can control the solenoid valve to close, so that the faucet stops dispensing water.

[0193] In actual operation, when the user needs to stop the water flow from the faucet, the operating handle is turned in the first direction to the first target position, and the water outlet 111 of the faucet stops flowing. The water cut-off control process is simple, and the handle will automatically reset after reaching the target position, without the need for the user to perform a reset operation.

[0194] In some embodiments, when the faucet is in a water-off state, the user receives a fifth input to the first trigger 420 on the faucet. In response to the fifth input, the water purifier can also be controlled to produce water, and the solenoid valve can be controlled to open so that water can flow from the faucet outlet 111 for the user's use.

[0195] When the faucet is currently in the water-dispensing state, it receives the sixth input from the user to the first trigger 420 on the faucet. In response to the sixth input, it controls the faucet outlet 111 to cut off the water flow.

[0196] Understandably, the fifth input is the command to control the faucet to dispense water, and the sixth input is the command to control the faucet to shut off the water. Whether the user inputs the fifth or sixth input to the first trigger 420 depends only on whether the faucet is currently in a water-off or water-dispensing state.

[0197] The first trigger 420 is installed on the faucet and is a non-contact trigger. It can trigger the input signal by receiving the obstruction signal within the target distance, so that the water supply system can receive the fifth and sixth inputs.

[0198] The target distance is the effective distance at which the first trigger 420 can receive the input signal. When the area outside the target distance is blocked, the first trigger 420 cannot be effectively triggered, and the control of water flow and water cut-off of the faucet cannot be realized.

[0199] The target distance of the first trigger 420 can be set according to the type of the first trigger 420 and the usage environment of the water supply system.

[0200] In actual implementation, the first trigger 420 can be a trigger device that emits infrared rays. Through the principle of infrared reflection, it receives the infrared rays reflected by the user's shield and forms an electronic control signal in the internal integrated circuit, namely the fifth input and the sixth input, to control the water flow and water cut-off of the faucet.

[0201] Taking the first trigger 420 as an infrared triggering device and the water supply system as an example of a kitchen scenario, the target distance can be set to 20 centimeters. By blocking the first trigger 420 within a 20-centimeter range, the water supply from the faucet can be controlled. The effective range of 20 centimeters can effectively prevent other devices in the kitchen from falsely triggering the first trigger 420.

[0202] The first trigger 420 is highly sensitive, simplifying the control process of water flow from and off the tap. Furthermore, the target distance setting can effectively prevent false triggering and improve the overall operability of the water supply system.

[0203] In some embodiments, after receiving the fifth input, it is also necessary to make a further judgment on whether to control the water flow from the faucet based on the water inlet temperature.

[0204] In actual implementation, when a user blocks the first trigger 420 and the duration of the fifth input does not exceed the target duration, it is called a brief blockage; when a user blocks the first trigger 420 and the duration of the fifth input exceeds the target duration, it is called a continuous blockage.

[0205] It is understandable that the fifth input received will be different depending on the duration of the user's blocking of the first trigger 420. Based on the different fifth inputs and the difference between the current water inlet temperature and the target temperature, it is determined whether to control the water outlet 111 of the faucet to flow.

[0206] If the current inlet water temperature is not higher than the target temperature and the duration of the fifth input is shorter than the target duration, then the water outlet 111 of the faucet will be controlled to flow out. The water temperature flowing out of the faucet is below the target temperature and can flow out directly without scalding the user.

[0207] If the user continuously blocks the first trigger 420, and the duration of the fifth input is not shorter than the target duration, the user can directly control the water flow from the faucet without needing to determine whether the water temperature at the faucet exceeds the target temperature.

[0208] If the current water temperature entering the faucet is higher than the target temperature, and the user blocks the first trigger 420, and the duration of the fifth input is shorter than the target duration, then the water outlet 111 of the faucet will be cut off, and water with a temperature higher than the target temperature will not flow out directly to avoid scalding the user.

[0209] In actual operation, if the duration of the fifth input is shorter than the target duration, the water outlet 111 of the faucet will be shut off. Water with a temperature higher than the target temperature will not flow out directly. The faucet will also display a reminder message on the display screen 450 or the breathing light 460 will flash in the target manner to remind the user.

[0210] The faucet's display screen 450 shows reminder information including the current water temperature at the faucet inlet and a prompt indicating that the first trigger 420 is continuously blocked from controlling water flow.

[0211] The faucet's breathing light 460 flashes in a targeted manner, wherein the targeted manner can be manifested in at least one of the following ways: target flashing color, target flashing interval, and target flashing brightness, etc.

[0212] Of course, in other embodiments, the target flashing mode of the breathing light 460 may also be in other forms, which can be determined according to actual needs. This application embodiment does not limit this.

[0213] The control method provided in this embodiment of the invention controls the operation actions such as water outlet start / stop, water temperature, and water flow in the water supply system by rotating the handle in the first and second directions to input the first and second inputs, and by inputting the third input through the first sensor 440. The actions controlled by the three inputs can be combined and replaced. The control method of this invention realizes intelligent control of the water supply system in terms of quantitative control, temperature adjustment, and water flow through the handle and the first sensor 440.

[0214] The following describes a specific implementation method.

[0215] like Figure 26 As shown, the water supply system is powered on and in standby mode. The water outlet 111 of the faucet is in a water-off state. Users can obtain water in the following two ways.

[0216] First, turn the handle to input the water input.

[0217] Turn the faucet handle in the first direction to the first target position to generate a corresponding electronic control signal. The water supply system receives the water intake input from the handle and responds to the water intake input by controlling the water purifier to purify water and opening the solenoid valve, so that water flows out of the faucet outlet 111.

[0218] The handle is easy to rotate, and after being rotated to the target position, the handle can be reset by the elastic force of the elastic element 360 degrees, without the need for user operation, making the water dispensing process simple and quick.

[0219] Secondly, the first trigger 420 is activated to input the infrared water intake input.

[0220] When the user triggers the first trigger 420, the water supply system receives the infrared water intake input. In response to the infrared water intake input, the system controls the water purifier to purify water and the solenoid valve to open, so that water flows out of the faucet outlet 111.

[0221] The first trigger 420 is only valid if it is triggered within the target distance range. The non-contact triggering process is not only simple and quick, but also effectively avoids accidental operation.

[0222] Correspondingly, the water outlet 111 of the faucet is currently in the water-flowing state. The user can control the water outlet 111 of the faucet to stop water flow by turning the handle in the first direction to output the handle water-stop input, or by blocking the first trigger 420 to input the infrared water-stop input.

[0223] Users can also control the faucet to dispense a fixed amount of water by operating the first sensor 440.

[0224] In practice, the system receives quantitative input from the user via a button on the first sensor 440 on the handle, and adjusts the water flow level of the faucet in response to the quantitative input.

[0225] Taking the user's button input that the dwell time on the first sensor 440 does not exceed the third target time as an example, the user controls the single adjustment of the quantitative water output level of the faucet and displays the current quantitative water output level on the display screen 450.

[0226] When the user inputs a quantitative amount into the first sensor 440 using a button, the first quantitative water output level is displayed on the display screen 450. When the user inputs a quantitative amount into the first sensor 440 using a button, the second quantitative water output level is displayed on the display screen 450. When the user inputs a quantitative amount into the first sensor 440 using a button, the third quantitative water output level is displayed on the display screen 450.

[0227] Users can also input a quantitative amount again into the first sensor 440 to control the flow into a custom quantitative level. Users can adjust the custom quantitative water output level through the display screen 450 and the first sensor 440.

[0228] After the user completes the control of the quantitative water output level, the user can then control the water output of the faucet outlet 111 by turning the handle in the first direction to output the handle water input, or by blocking the first trigger 420 to input the infrared water input.

[0229] Users can also control the water temperature setting of the faucet by turning the handle in the second direction.

[0230] In practice, the system receives quantitative input from the user on the handle and adjusts the water temperature setting of the faucet in response to the quantitative input.

[0231] Taking the example that the duration of the handle being held in the second target position is shorter than the duration of the second target, the water temperature setting of the faucet is adjusted once, and the current water temperature setting is displayed on the display screen 450.

[0232] The system receives the user's first quantitative input of the handle, which displays the first temperature setting on the display screen 450. The second quantitative input displays the second temperature setting on the display screen 450, and the third quantitative input displays the third temperature setting on the display screen 450, and so on.

[0233] After the user has adjusted the water temperature setting, the user can control the water outlet 111 to dispense water by turning the handle in the first direction to output the handle water intake input, or by blocking the first trigger 420 to input the infrared water intake input.

[0234] It is understandable that users can adjust the water flow and water temperature simultaneously when taking water. That is, they can adjust the temperature first and then the quantity, or they can adjust the quantity first and then the temperature. After adjusting the water flow and water temperature, they can control the water outlet 111 to dispense water by turning the handle in the first direction or blocking the first trigger 420.

[0235] The control method provided by this invention controls the start and stop of water flow, water flow rate and water temperature of the faucet through the handle, the first sensor 440 and the first trigger 420. The control accuracy of each operating component is high, and the accurate control of different actions of the faucet can be achieved. It can effectively avoid the occurrence of misoperation, improve the overall operability of the water supply system, and realize the intelligent control of the water supply system.

[0236] The following is combined Figures 1-25 A faucet according to an embodiment of the present invention.

[0237] like Figure 1 As shown, the faucet provided in this embodiment of the invention includes: a faucet assembly 200, a handle assembly 300, an elastic element 360, a first sensor 430, a first sensor 440, and a controller.

[0238] Faucet assembly 200 is the body of the faucet, and handle assembly 300 is located on the handle of the faucet. By installing handle assembly 300 on faucet assembly 200, the handle and body of the faucet are installed.

[0239] When the handle assembly 300 is pivotally mounted on the faucet assembly 200, the handle assembly 300 can rotate around the faucet assembly 200, rotating from an initial position to a target position.

[0240] An elastic element 360 is installed between the faucet assembly 200 and the handle assembly 300, and the elastic element 360 is elastically connected to the faucet assembly 200 and the handle assembly 300 respectively.

[0241] When the handle assembly 300 can rotate around the faucet assembly 200 to the target position, the elastic element 360 deforms to generate an elastic force, and the elastic element 360 delivers the elastic force to the handle assembly 300, so that the handle assembly 300 resets from the target position back to the initial position.

[0242] In related technologies, after the faucet handle is rotated around the faucet, the user usually needs to operate it again to rotate the handle in the opposite direction to control the handle to return to its original position.

[0243] In this embodiment of the invention, after the handle assembly 300 is rotated to the target position, it can be automatically reset by the elastic force of the elastic element 360, without requiring the user to operate again, making the water retrieval process simpler and more convenient.

[0244] The first sensor 430 is used to identify the user's operation and generate a first trigger signal. The first trigger signal can control at least one of the following operations: the start and stop of the faucet's water flow, the water temperature and the water flow rate, or a combination of the above operations.

[0245] The first sensor 430 can be installed on the faucet assembly 200 or the handle assembly 300, or different parts of the first sensor 430 can be installed on the faucet assembly 200 and the handle assembly 300 respectively.

[0246] In practice, the user operates the handle assembly 300 to rotate to the target position, the first sensor 430 is electrically connected to the controller, the first sensor 440 is used to receive the user's input, the first sensor 430 generates a first trigger signal, and then controls the faucet's water flow start / stop, water temperature or water flow, etc.

[0247] The first sensor 440 is installed inside the handle assembly 300 and can be electrically connected to the controller. It can also be electrically connected to the controller through the control board of the first sensor 430 in the handle assembly 300, which reduces the distribution of wires inside the faucet. Furthermore, since both the first sensor 430 and the first sensor 440 are installed in the handle assembly 300, the overall operability of the faucet handle is improved.

[0248] The first sensor 440 is installed in the mounting slot 512. When the first sensor 440 is triggered, it checks the corresponding electronic control device to control the operation of the faucet, such as starting and stopping the water flow, water temperature and flow rate.

[0249] Both the first sensor 430 and the first sensor 440 can generate corresponding electronic control signals to control the operation of the faucet, such as starting and stopping the water flow, water temperature, and water flow rate.

[0250] According to the embodiments provided by the present invention, by installing a first sensor 430 and a first sensor 440 on the handle, the operation of the faucet, such as water flow start / stop, water temperature, or water flow rate, can be controlled by the handle rebounding and the input to the first sensor 440, thereby realizing intelligent control of the faucet and making it convenient for users to use.

[0251] In some embodiments, the faucet assembly 200 is provided with inlet and outlet water pipes and electrical control circuits. The upper shell 100 is installed on the faucet assembly 200, and the outlet 111 of the upper shell 100 is connected to the outlet water pipe of the faucet assembly 200 to provide water for user use.

[0252] The controller is the control device for the faucet. The controller is installed inside the upper housing 100. The first sensor 430 and the first sensor 440 are connected to the signal transmission line of the controller to realize the rapid control of the faucet's water flow start and stop, water temperature or water flow rate.

[0253] The first trigger 420 is a non-contact trigger installed inside the upper housing 100. It is used to receive obstruction signals and control the water flow or water cut-off at the faucet outlet 111.

[0254] When the first trigger 420 detects a signal of obstruction from above, it generates a corresponding electrical control signal. The controller then controls the water flow of the faucet based on the electrical control signal generated by the first trigger 420.

[0255] In this embodiment, when the faucet is in standby mode, the user blocks the first trigger 420 to control the faucet outlet 111 to dispense water; when the faucet is in water dispensing mode, the user blocks the first trigger 420 to control the faucet to shut off the water flow.

[0256] In some embodiments, the first trigger 420 is an infrared trigger. The infrared trigger receives the blocking signal through the principle of infrared reflection, generates a corresponding electrical control signal, and is electrically connected to the controller to control the start and stop of water flow from the faucet.

[0257] Infrared trigger devices have very low power consumption, good concealment, and are easy to install within the upper housing 100mm to control water output. In addition, infrared triggers are inexpensive, which can reduce the manufacturing and maintenance costs of faucets.

[0258] Infrared triggers can be divided into active and passive types.

[0259] Firstly, an active infrared trigger.

[0260] In this embodiment, the infrared trigger includes an infrared emitter 421 and an infrared sensing probe 422.

[0261] Infrared transmitter 421 is used to emit infrared rays, and infrared sensor 422 is used to receive infrared rays reflected back by obstacles. In other words, it receives the corresponding blocking signal, generates an electronic control signal, and thus controls the water tap to start and stop.

[0262] The infrared transmitter 421 and the infrared sensor 422 are distributed along the width of the upper shell 100 and located on both sides of the pivot axis to avoid mutual obstruction between the infrared emission channel and the infrared reception channel, thereby improving the triggering accuracy of the infrared trigger.

[0263] The infrared sensor 422 can receive the obstruction signal reflected by a human body or other objects. In this way, when the user is holding an object, the object can be used to trigger the infrared sensor 422 to control the water flow of the faucet, thus improving the convenience of user operation.

[0264] For example, in a kitchen environment, when a user is chopping vegetables with a knife, they can directly use the knife to block the water flow on the faucet cover 100, without having to put the knife down, thus improving the ease of operation.

[0265] Secondly, passive infrared triggers.

[0266] In this embodiment, the infrared trigger is a passive infrared trigger.

[0267] A passive infrared trigger is used to receive infrared signals emitted by a human body or other heat source objects. The user covers the passive infrared trigger with their hand, causing it to receive the infrared signal and control the water flow of the faucet to start and stop.

[0268] Passive infrared triggers cannot receive obstruction signals reflected by non-heat source objects, which can effectively avoid false triggering and ensure that water output control is actively triggered by the user.

[0269] Taking the first trigger 420 as an example, which includes an infrared transmitter 421 and an infrared sensing probe 422.

[0270] like Figure 8 As shown, two trigger mounting holes of different shapes are provided on the upper shell 100. The infrared transmitter 421 extends into the square trigger mounting hole, and the infrared sensor 422 extends into the round trigger mounting hole.

[0271] Understandably, the upper housing 100 has two trigger mounting holes of different shapes to facilitate the installation and maintenance of the infrared transmitter 421 and the infrared sensor 422.

[0272] In some embodiments, such as Figure 1 As shown, the faucet also includes a display screen 450, which is installed inside the upper housing 100.

[0273] The display screen 450 is used to display the current water temperature, filtration status, and water flow rate of the faucet, as well as the adjustment process.

[0274] The display screen 450 may be a display screen 450 used only for displaying information, or it may be an operable display screen 450 with both information display and touch operation functions.

[0275] The display screen 450 is electrically connected to the controller, thereby displaying or controlling the operation of the faucet such as water flow start / stop, water temperature, or water flow rate, further improving the intelligence of the faucet.

[0276] In some embodiments, such as Figure 1 As shown, the faucet also includes: inner core 700.

[0277] The faucet assembly 200 has an inner core 700, in which an external water source or power source is arranged through inlet and outlet water pipes and electrical control circuits. The inner core 700 can be fixed to the user's platform by means of threaded connectors or clips 123, thereby fixing the position of the water pipes and electrical control circuits in the inner core 700.

[0278] The inner core 700 is located inside the faucet assembly 200. It is a long cylindrical structure with open ends. The water pipe connecting to the external water source extends from the bottom of the inner core 700, passes through the inner core 700, and is distributed in the upper shell 100.

[0279] The rotating buckle 800 is a connecting component, with one end connected to the faucet assembly 200 and the other end connected to the upper shell 100. The rotating buckle 800 is located at the connection end between the faucet assembly 200 and the upper shell 100.

[0280] The rotating buckle 800 limits the faucet assembly 200 and the upper shell 100 in the length direction of the faucet assembly 200. The faucet assembly 200 and the upper shell 100 are fixed in the length direction. The upper shell 100 can rotate around the faucet assembly 200 and will not fall off the faucet assembly 200.

[0281] like Figure 5 As shown, the rotating buckle 800 can be a ring-shaped shell with a hollow interior. Water pipes and wires arranged in the inner core 700 extend from the bottom of the rotating buckle 800, pass through the rotating shell, and are then arranged in the upper shell 100 of the faucet.

[0282] In some embodiments, the end of the swivel buckle 800 connected to the upper shell 100 is an outwardly extending flange 812, which is supported by the support step surface 811 inside the upper shell 100.

[0283] like Figure 6 As shown, the flange 812 extending outward from the rotating buckle 800 forms a boss structure. Corresponding to the direction away from the faucet assembly 200 inside the upper shell 100, a supporting step surface 811 is provided. The supporting step surface 811 supports the flange 812 of the rotating buckle 800, thereby realizing the limiting of the rotating buckle 800 on the upper shell 100 in the length direction of the faucet assembly 200.

[0284] It is understandable that the upper shell 100 is a hollow cavity structure. The lower end of the upper shell 100 has a water outlet 111 on one side and an opening on the other side for connecting with the faucet assembly 200. The supporting step surface 811 is set on the inner peripheral wall of the opening at the lower end of the upper shell 100 that connects with the faucet assembly 200.

[0285] In actual implementation, the rotating buckle 800 extends from the opening at the lower end of the upper shell 100 that connects to the faucet assembly 200, and the flange 812 is supported on the support step surface 811. The flange 812 and the support step surface 811 are tightly connected to achieve the connection between the rotating buckle 800 and the upper shell 100.

[0286] In some embodiments, a notch 813 is provided in one of the flange 812 of the swivel buckle 800 and the support step surface 811 of the upper shell 100, and a positioning protrusion is provided in the other. The positioning protrusion extends into the notch 813 to ensure the stability of the swivel buckle 800 in the circumferential direction.

[0287] In practice, a positioning protrusion can be set on the flange 812 and a notch 813 can be set on the supporting step surface 811; alternatively, a notch 813 can be set on the flange 812 and a positioning protrusion can be set on the supporting step surface 811.

[0288] like Figure 7 As shown, taking the example of setting a notch 813 on the flange 812 and setting a positioning protrusion on the supporting step surface 811,

[0289] When the swivel buckle 800 and the upper shell 100 are connected, the flange 812 on the swivel buckle 800 is supported by the support step surface 811 of the upper shell 100. The positioning protrusion of the support step surface 811 extends into the notch 813 of the flange 812. The swivel buckle 800 and the upper shell 100 are connected together. The swivel buckle 800 is not easy to slide, and the upper shell 100 and the swivel buckle 800 are not easy to fall off.

[0290] This ensures that the rotating buckle 800 limits the upper shell 100 in the length direction of the faucet assembly 200, and also ensures the circumferential stability of the rotating buckle 800.

[0291] In some embodiments, the annular swivel buckle 800 is provided with a plurality of locking portions 814 spaced apart along the circumferential direction. The locking portions 814 are used to cooperate with the locking protrusions 815 provided on the inner peripheral wall of the faucet assembly 200 to connect the faucet assembly 200 and the swivel buckle 800 together.

[0292] like Figure 7 As shown, the rotating buckle 800 is provided with multiple locking parts 814 spaced apart along the circumferential direction. The end of the locking part 814 forms a small protrusion with a small front end and a large tail end.

[0293] The rotating buckle 800 can be a plastic part with a certain degree of elasticity. When the rotating buckle 800 is installed with the faucet assembly 200, the front end of the small protrusion of the locking part 814 is narrow and has a beveled surface, which guides the installation of the rotating buckle 800. In addition, the elastic contraction radius of the plastic part of the rotating buckle 800 is reduced, so the rotating buckle 800 will not be stuck by the locking protrusion 815 of the faucet assembly 200.

[0294] After the locking part 814 of the rotating buckle 800 passes the locking protrusion 815, the plastic part of the rotating buckle 800 elastically recovers. The rear end of the small protrusion of the locking part 814 is wide and tightly overlaps with the locking protrusion 815. The locking part 814 of the rotating buckle 800 is firmly locked with the locking protrusion 815, and the rotating buckle 800 will not fall off the faucet assembly 200.

[0295] In some embodiments, the swivel buckle 800 may be a cylindrical structure, including: a main cylinder 816, a flange 812, and a plurality of locking portions 814.

[0296] like Figure 7 As shown, the outer peripheral wall of the main cylinder 816 of the rotating buckle 800 is provided with a weakening groove 817 to reduce the strength of the rotating buckle 800, so that the rotating buckle 800 can shrink and recover within a certain range, avoiding crack damage caused by excessive strength of the main cylinder 816.

[0297] Understandably, the weakening groove 817 reduces the strength of the rotating buckle 800 by a certain amount. The groove depth of the weakening groove 817 should not be too deep to avoid damage caused by the rotating buckle 800 being too weak.

[0298] The depth and number of weakening grooves 817 on the main cylinder 816 can be adjusted according to the size, thickness and material of the rotating buckle 800.

[0299] The flange 812 is connected to one end of the main cylinder 816 and extends outward to form a boss structure. Multiple locking parts 814 are connected to the other end of the main cylinder 816 and are distributed circumferentially around the main cylinder 816.

[0300] like Figure 6 As shown, the flange 812 of the rotating buckle 800 is tightly engaged with the support step surface 811 of the upper shell 100, and the locking part 814 is engaged with the locking protrusion 815 of the faucet assembly 200, thereby limiting the upper shell 100 and the faucet assembly 200 in the length direction of the faucet assembly 200. The upper shell 100 is connected to the faucet assembly 200 through the rotating buckle 800, and the upper shell 100 will not fall off the faucet assembly 200 and can rotate on the faucet assembly 200.

[0301] In some embodiments, the upper shell 100 is provided with a pivot section 140 at the end where it is connected to the faucet assembly 200. The pivot section 140 extends into the faucet assembly 200 to realize the pivotal installation of the upper shell 100 and the faucet assembly 200.

[0302] like Figure 2 As shown, the pivot section 140 of the upper shell 100 is provided with a pivot groove 141. The pivot section 140 of the upper shell 100 extends into the faucet assembly 200. An elastic washer 142 is provided in the pivot groove 141. When the upper shell 100 rotates relative to the faucet, the resistance generated by the elastic washer 142 can counteract the collision force between the upper shell 100 and the faucet, thereby improving the user's feel when rotating the upper shell 100.

[0303] The upper shell 100 and the faucet assembly 200 are typically made of metal. The upper shell 100 is pivotally mounted on the faucet assembly 200. When the upper shell 100 is rotated by the rotating buckle 800, the upper shell 100 and the faucet assembly 200 collide, causing noise and damage to the upper shell 100 and the faucet assembly 200.

[0304] The upper shell 100 extends into the pivot section 140 of the faucet assembly 200 and is provided with a pivot groove 141. An elastic washer 142 is installed in the pivot groove 141. The resistance generated by the elastic washer 142 can offset the collision force between the upper shell 100 and the faucet assembly 200, improve the user's hand feel, reduce the noise and damage generated between the upper shell 100 and the faucet assembly 200, and extend the service life of the faucet.

[0305] In some embodiments, a lubricating ring 720 may also be installed between the upper shell 100 and the faucet assembly 200. The lubricating ring 720 is clamped between the end face of the upper shell 100 and the support surface 721 of the inner peripheral wall of the faucet assembly 200.

[0306] like Figure 6 As shown, the lubrication ring 720 is an annular structure between the upper shell 100 and the faucet assembly 200. It is clamped between the upper shell 100 and the faucet assembly 200, can rotate freely, and is not connected to the upper shell 100 or the faucet assembly 200.

[0307] The lubricating ring 720 provides rotational lubrication for the upper shell 100 and the faucet assembly 200. The lubricating ring 720 is sandwiched between the upper shell 100 and the faucet assembly 200, so that the upper shell 100 does not directly contact the faucet assembly 200, thereby improving the rotational flexibility of the upper shell 100 and reducing mechanical wear caused by direct contact between the upper shell 100 and the faucet assembly 200.

[0308] Understandably, the lubricating ring 720 clamped between the upper shell 100 and the faucet assembly 200 is replaceable. When the rotation of the upper shell 100 on the faucet assembly 200 becomes stuck, the lubrication of the upper shell 100 on the faucet assembly 200 can be improved by replacing the lubricating ring 720, thereby extending the service life of the faucet.

[0309] The lubricating ring 720 can be made of wear-resistant and friction-reducing materials. In specific implementation, it can be made of polyoxymethylene resin. Polyoxymethylene resin has good stability, excellent friction resistance and mechanical strength, which can further improve the transmission performance of the lubricating ring 720 between the upper shell 100 and the faucet assembly 200 and the service life of the lubricating ring 720.

[0310] In some embodiments, such as Figure 5 As shown, the lubrication ring 720 can be stepped, and the stepped part of the lubrication ring 720 is the part that contacts the end face of the upper shell 100.

[0311] like Figure 6 As shown, the stepped lubricating ring 720 has a stepped portion 722, which is the part that is relatively raised relative to the other end, in contact with the upper shell 100, and another part in contact with the support surface 721 of the faucet assembly 200. The lubricating ring 720 is sandwiched between the upper shell 100 and the faucet assembly 200.

[0312] The stepped portion 722 of the lubrication ring 720 can limit the angle of rotation of the upper shell 100 on the faucet assembly 200, prevent the upper shell 100 from rotating 360 degrees on the faucet assembly 200, and avoid damage to the water pipes arranged in the upper shell 100 and the faucet assembly 200.

[0313] In actual operation, the stepped portion 722 of the lubricating ring 720 supports the upper shell 100, and the platform portion 723 supports the faucet assembly 200. When the upper shell 100 drives the rotating buckle 800 to rotate, when the lubricating ring 720 rotates to a certain position, the stepped protrusions of the stepped portion 722 and the platform portion 723 will contact the end face of the upper shell 100 or the supporting surface 721 of the faucet assembly 200 to prevent the lubricating ring 720 from rotating excessively, thereby limiting the rotation of the upper shell 100.

[0314] For example, such as Figure 6 As shown, the left side of the lubrication ring 720 is higher than the right side. When rotating, the stepped boss between the left and right sides will stop against the end face of the upper shell 100 or the support surface 721 of the faucet assembly 200 to prevent the lubrication ring 720 from rotating excessively.

[0315] The central angle of the stepped portion 722 of the lubrication ring 720 is the angle that the upper shell 100 can rotate. For example, if the central angle of the stepped portion 722 of the lubrication ring 720 is set to 60 degrees, the upper shell 100 can rotate freely within a 60-degree range on the faucet assembly 200.

[0316] It is understandable that the upper shell 100 and the lubricating ring 720 rotate in the same direction, and can rotate together from left to right or from right to left. When rotating in different directions, the different stepped parts 722 of the lubricating ring 720 stop and prevent the lubricating ring 720 from rotating excessively.

[0317] In some embodiments, such as Figure 18 As shown, the handle assembly 300 has a cavity structure. The end face of the handle assembly 300 cavity structure that is away from the faucet assembly 200 is the first end face 511, and the end face that is close to the faucet assembly 200 is the second end face.

[0318] A mounting groove 512 is provided on the first end face 511. The mounting groove 512 is used to install the first sensor 440. The shape of the mounting groove 512 matches the first sensor 440. For example, if the first sensor 440 is a circular flat button, the corresponding mounting groove 512 is a circular mounting groove 512 with a certain depth that can accommodate the first sensor 440.

[0319] A mounting structure for installing the faucet assembly 200 is provided on the second end face. The handle assembly 300 and the faucet assembly 200 can be securely installed by means of threaded connectors or snap-fit ​​structures 123.

[0320] The first sensor 440 is installed in the mounting slot 512. The first sensor 440 can be triggered in the direction of the first end face 511. That is, the trigger surface of the first sensor 440 that receives the user operation signal is set towards the first end face 511.

[0321] In actual operation, when a user lightly touches the first sensor 440 on the first end face 511, the first sensor 440 collects the user's light sensor signal, thereby triggering the first sensor 440 to control the water flow, water temperature, and water volume of the faucet. Furthermore, the user can control the water flow, water temperature, and water volume of the faucet by rotating the handle in different directions.

[0322] In some embodiments, such as Figure 19 As shown, an annular mounting shell 520 is provided in the mounting groove 512 of the handle body 500. The mounting shell 520 is used to fix the first sensor 440 in the mounting groove 512. The shape of the mounting shell 520 matches the shape of the mounting groove 512, and the circular mounting groove 512 corresponds to the circular mounting shell 520.

[0323] like Figure 21 As shown, the inner side of the mounting housing 520 is provided with a support step 521. The support step 521 is disposed away from the first end face 511. The first sensor 440 is tightly connected with the support step 521. The support step 521 abuts against the first sensor 440. The first sensor 440 is installed on the support step 521.

[0324] It is understandable that the diameter of the first sensor 440 is smaller than the diameter of the end of the mounting housing 520 that is away from the first end face 511, so that the first sensor 440 can be installed in the mounting housing 520 without causing any obstruction to the installation of the first sensor 440.

[0325] Furthermore, the diameter of the first sensor 440 is larger than the diameter of the end of the mounting housing 520 near the first end face 511. That is, the diameter of the first sensor 440 is slightly larger than the diameter of the formed support step 521, which can ensure the support and stability of the support step 521 for the first sensor 440.

[0326] In some embodiments, the first sensor 440 is installed inside the mounting housing 520. After the mounting housing 520 is installed inside the mounting groove 512 of the handle body 500, sealant is filled in the space formed by the mounting housing 520, the first sensor 440 and the bottom wall of the mounting groove 512 to form a sealed and waterproof structure for the first sensor 440.

[0327] In actual implementation, after the mounting housing 520 and the first sensor 440 are assembled, the sensor can be installed in the mounting groove 512. Then, hot melt adhesive can be injected into the space formed by the mounting housing 520, the first sensor 440 and the bottom wall of the mounting groove 512. After the temperature cools down, the hot melt adhesive hardens, which can make the first sensor 440 achieve IPX7 waterproof rating.

[0328] Understandably, the sealant is filled on the non-trigger surface of the first sensor 440 that is electrically connected to other control devices and transmits electronic control signals. This prevents the sealant from blocking the trigger surface that receives user operation signals. While enabling the first sensor 440 to achieve IPX7 waterproof rating, it does not affect the reception and transmission of the trigger signal of the first sensor 440.

[0329] In some embodiments, such as Figure 20 and Figure 22 As shown, a light-sensitive button sealing ring 530 is also provided to cooperate with the mounting shell 520, and a mounting shell sealing groove 522 for mounting the light-sensitive button sealing ring 530 is provided on the outer peripheral wall of the mounting shell 520.

[0330] The light-sensitive button sealing ring 530 can be a rubber sealing ring with elasticity and appropriate mechanical strength. The light-sensitive button sealing ring 530 has stable performance, is not easily corroded, and will not contaminate the medium.

[0331] When the mounting shell 520 is installed in the mounting groove 512, the photosensitive button sealing ring 530 is installed between the mounting shell 520 and the mounting groove 512. The photosensitive button sealing ring 530 elastically abuts against the inner peripheral wall of the mounting groove 512, forming an elastic sealing structure between the mounting shell 520 and the mounting groove 512, thereby improving the stability and sealing of the mounting shell 520 inside the mounting groove 512.

[0332] In some embodiments, such as Figure 20 As shown, the mounting housing 520 may include a first segment 523 and a second segment 524.

[0333] The first segment 523 of the mounting shell 520 is the part that is away from the first end face 511 of the handle body 500, and the second segment 524 of the mounting shell 520 is the part that is close to the first end face 511 of the handle body 500.

[0334] like Figure 21 As shown, the inner peripheral wall of the first segment 523 of the mounting shell 520 protrudes relative to the inner peripheral wall of the second segment 524, and the protruding part forms a support step 521, which is tightly connected to the light-sensitive button.

[0335] Understandably, the inner peripheral wall of the first segment 523 of the mounting shell 520 protrudes relative to the inner peripheral wall of the second segment 524. The thickness of the first segment 523 of the mounting shell 520 is greater than the thickness of the second segment 524. This not only forms a supporting step 521 on the inner peripheral wall of the mounting shell 520 to support the light-sensitive button, but also provides sufficient thickness for the setting of the mounting shell sealing groove 522, thus preventing the mounting shell 520 from being weakened due to the setting of the mounting shell sealing groove 522.

[0336] The thickness of the second segment 524 of the mounting shell 520 is less than that of the first segment 523. This effectively reduces the weight of the mounting shell 520 while providing operating space for the installation of the optical button inside the mounting shell 520, without hindering the installation of the optical button.

[0337] In some embodiments, a light-sensitive button limiting rib 525 is provided on one of the inner peripheral wall of the mounting shell 520 and the outer peripheral wall of the light-sensitive button, and a light-sensitive button limiting groove 526 that cooperates with the light-sensitive button limiting rib 525 is provided on the other, so as to improve the installation stability of the light-sensitive button in the mounting shell 520 and effectively prevent the light-sensitive button from rotating in the mounting shell 520.

[0338] When the mounting shell 520 and the light-sensitive button are installed together, the light-sensitive button limiting rib 525 extends into the light-sensitive button limiting groove 526 to achieve a stable installation of the mounting shell 520 and the light-sensitive button.

[0339] It is understandable that the number of light-sensitive button limiting ribs 525 and light-sensitive button limiting grooves 526 are equal and their positions are opposite.

[0340] In specific implementation, a light-sensitive button limiting rib 525 can be set on the mounting shell 520, and a light-sensitive button limiting groove 526 can be set on the light-sensitive button accordingly; alternatively, a light-sensitive button limiting rib 525 can be set on the light-sensitive button, and a light-sensitive button limiting groove 526 can be set on the mounting shell 520 accordingly.

[0341] Taking the installation shell 520 as an example, which has a light-sensitive button limiting rib 525 and a light-sensitive button limiting groove 526 on the light-sensitive button.

[0342] like Figure 20 and Figure 21 As shown, the mounting shell 520 is provided with a light-sensitive button limiting rib 525, and the light-sensitive button is provided with a corresponding light-sensitive button limiting groove 526. When the mounting shell 520 and the light-sensitive button are assembled, the light-sensitive button limiting rib 525 extends into the light-sensitive button limiting groove 526 to achieve a stable installation of the mounting shell 520 and the light-sensitive button.

[0343] By setting up the light-sensitive button limiting rib 525 and the light-sensitive button limiting groove 526, the mounting shell 520 and the light-sensitive button are stably installed by utilizing the structure of the mounting shell 520 and the light-sensitive button itself. This effectively prevents the light-sensitive button from rotating inside the mounting shell 520, reduces the number of external mounting parts, and facilitates the installation and maintenance of the mounting shell 520 and the light-sensitive button.

[0344] In some embodiments, the upper housing 100 includes: a main housing 110, a mounting box 120, and a display cover 130.

[0345] like Figure 1As shown, the main housing 110 is the mounting part of the upper housing 100 and the faucet body 210. One end of the main housing 110 is pivotally mounted on the faucet body 210, and the other end of the main housing 110 is provided with a water outlet 111.

[0346] The main housing 110 is a hollow cavity structure, and the mounting box 120 is installed inside the cavity structure of the main housing 110.

[0347] The mounting box 120 is a box-shaped structure with an open bottom. The circuit board 410 is installed inside the mounting box 120 and is inserted from the open bottom of the mounting box 120 for installation.

[0348] The display cover 130 is installed above the mounting box 120. The shape of the display cover 130 matches the mounting box 120, covering the mounting box 120 and preventing water from entering the mounting box 120.

[0349] Understandably, the display cover 130 is made of a transparent material and will not obstruct the circuit board 410 from transmitting or receiving signals.

[0350] During installation, the main housing 110 can be installed on the faucet body 210, and then the mounting box 120 with the circuit board 410 installed can be fixedly installed on the main housing 110. Finally, the display cover 130 is fixedly installed on the top of the mounting box 120 to form a sealed and waterproof structure to prevent water from contacting the circuit board 410 and damaging the circuit board 410.

[0351] When installing the main housing 110, mounting box 120 and display cover 130, threaded connectors, snap-fit ​​123 or other installation methods can be used.

[0352] In some embodiments, a first sealing groove 121 is provided on the top surface of the mounting box 120, that is, the relatively sealed end of the mounting box 120. When installing the display cover 130 and the mounting box 120, hot melt adhesive is injected into the first sealing groove 121 to achieve a fixed connection and seal between the display cover 130 and the mounting box 120.

[0353] The first sealing groove 121 on the top surface of the mounting box 120 is closed. When hot melt adhesive is injected, the hot melt adhesive flows in the first sealing groove 121 and fills the first sealing groove 121, so that the display cover 130 and the mounting box 120 are fixedly connected. It can also effectively prevent water from entering the mounting box 120 and thus damaging the first trigger 420 inside the mounting box 120.

[0354] In some embodiments, such as Figure 8 and Figure 9As shown, a second sealing groove 122 is provided in the inner ring of the first sealing groove 121, and a sealing ring is provided at the position of the second sealing groove 122 to prevent hot melt adhesive from flowing into the mounting box 120 when the first sealing ring is injected, thus preventing the first trigger 420 from being blocked.

[0355] The sealing ring provided in the second sealing groove 122 can be a rubber sealing ring with elasticity and appropriate mechanical strength, which has stable performance, is not easily corroded, and will not contaminate the medium.

[0356] The sealing ring is installed in the second sealing groove 122 and elastically abuts against the mounting box 120 and the display cover 130, forming an elastic sealing structure between the mounting box 120 and the display cover 130. This prevents the adhesive from the first sealing ring from flowing into the mounting box 120 and further improves the sealing performance of the mounting box 120 and the display cover 130.

[0357] In some embodiments, such as Figure 8 He Ru Figure 10 As shown, the peripheral wall of the mounting box 120 is provided with a protruding buckle 123, which is used to mount the mounting box 120 to the main housing 110.

[0358] The peripheral wall of the mounting box 120 may be provided with multiple protruding buckles 123. Multiple buckle protrusions 123 are provided at corresponding positions on the inner peripheral wall of the main housing 110, which engage with the buckles 123 on the peripheral wall of the mounting box 120 to achieve fixed installation of the mounting box 120 and the main housing 110.

[0359] The mounting box 120 is installed together with the main housing 110 by means of a snap-fit ​​123, which ensures the stability of the installation of the mounting box 120 and the main housing 110, while facilitating disassembly and maintenance.

[0360] By using the snap-fit ​​structure 123 on the periphery of the mounting box 120, the mounting box 120 and the main housing 110 are securely installed using the structure of the mounting box 120 itself, reducing the number of faucet mounting parts and facilitating the installation and maintenance of the mounting box 120 and the main housing 110.

[0361] The circuit board 410 is installed inside the mounting box 120. The circuit board 410 is bonded to the inner peripheral wall of the mounting box 120 by hot melt adhesive. Hot melt adhesive is injected at the contact position between the circuit board 410 and the inner peripheral wall of the mounting box 120. After the hot melt adhesive cools and solidifies, the circuit board 410 and the mounting box 120 are fixedly bonded.

[0362] It is understandable that the fixed bonding between the circuit board 410 and the mounting box 120 can ensure the installation stability of the circuit board 410 and the mounting box 120, while preventing water from entering the mounting box 120 and damaging the circuit board 410 and the first trigger 420 of the mounting box 120.

[0363] In some embodiments, such as Figure 10 As shown, a stepped surface 124 is provided on the inner peripheral wall of the mounting box 120. The stepped surface 124 faces the faucet body 210, that is, the end of the stepped surface 124 that faces the mounting box 120 is open.

[0364] When installing the circuit board 410 and the mounting box 120, the circuit board 410 is mounted on the stepped surface 124 and is tightly overlapped with the stepped surface 124.

[0365] It is understandable that the inner circle of the mounting box 120 at the step surface 124 is smaller than the outer circle of the circuit board 410, which can ensure the installation stability of the circuit board 410 on the step surface 124.

[0366] Hot melt adhesive is injected at the contact point between the circuit board 410 and the inner peripheral wall of the mounting box 120. The circuit board 410 abuts against the stepped surface 124, which prevents the hot melt adhesive from flowing into the mounting box 120 and obstructing the first trigger 420.

[0367] In some embodiments, such as Figure 11 and Figure 12 As shown, the handle assembly 300 includes: a support 310, a pressure cap 320, and a handle body 500.

[0368] The support 310 and the gland 320 can be connected by threaded fasteners, snap fasteners 123 or other connection methods. The support 310 and the gland 320 can also be an integrated structural component.

[0369] At least one of the support 310 and the pressure cap 320 is pivotally mounted to the faucet assembly 200 by means of a threaded connection, a snap 123 or other installation method, for the purpose of enabling the mating installation of the handle assembly 300 and the faucet assembly 200.

[0370] The elastic element 360 is located between the support 310 and the pressure cap 320. The elastic element 360 can be elastically connected to the support 310 or the pressure cap 320, or different parts of the elastic element 360 can be elastically connected to the support 310 and the pressure cap 320 respectively.

[0371] The handle body 500 is the operating component that the user directly contacts. The handle body 500 can be connected to the cover 320 by threaded connectors, snap clips 123 or other connection methods.

[0372] like Figure 11 As shown, the handle body 500 is installed on the pressure cap 320 of the handle assembly 300. The user operates the handle body 500 to control the handle assembly 300 to rotate to the target position, so that the first sensor 430 generates the first trigger signal to control the faucet's water intake, metering, and temperature control.

[0373] When the user stops operating the handle body 500, the elastic element 360 sends a reset elastic force to the handle assembly 300, causing the handle assembly 300 to reset from the target position to the initial position.

[0374] After the user controls the handle assembly 300 to rotate to the target position, the operation stops immediately and the handle immediately resets. This operation can be called a short turn. After the user controls the handle assembly 300 to rotate to the target position and stays there for the target duration, the operation stops again. During the target duration, the first sensor 430 continuously generates the first trigger signal. This operation can be called a long turn.

[0375] like Figure 11 As shown, the handle body 500 is connected to the pressure cover 320 via a threaded connector. The handle is installed onto the pressure cover 320 via a handle screw, thus achieving a secure connection between the handle body 500 and the pressure cover 320.

[0376] Furthermore, a decorative cap is installed on the part of the handle screw that protrudes 500mm from the handle body, which not only enhances the appearance of the handle but also prevents the handle screw from scratching the user.

[0377] In some embodiments, such as Figure 11 and Figure 12 As shown, the elastic element 360 is sleeved on the boss between the support 310 and the pressure cap 320, and the elastic element 360 is located between the support 310 and the pressure cap 320.

[0378] A boss facing the other component is provided on one of the two components, support 310 and pressure cap 320. Elastic member 360 is sleeved on the boss to realize the installation of elastic member 360 between support 310 and pressure cap 320.

[0379] In specific implementation, a boss facing the cover 320 can be provided on the support 310, or a boss facing the support 310 can be provided on the cover 320, or a boss facing the other component can be provided on both components.

[0380] Taking the example of providing a boss facing the other component on both the support 310 and the gland 320, such as... Figure 13 and Figure 15 As shown, a support boss 311 protruding toward the pressure cap 320 is provided on the support 310, and a pressure cap boss 321 protruding toward the support 310 is provided on the pressure cap 320.

[0381] When the support 310 and the gland 320 are installed, the support boss 311 and the gland boss 321 are joined to form a boss, and the elastic member 360 is sleeved on the boss formed by the joint of the support boss 311 and the gland boss 321.

[0382] The support 310 and the gland 320 can be connected together by threaded fasteners, snap clips 123 or other connection methods.

[0383] For example, such as Figure 12 As shown, a support screw post 316 is provided on the support 310, and a pressure cover threaded hole 324 is provided at the corresponding position on the pressure cover 320. The support 310 and the pressure cover 320 are connected together by the first screw 350.

[0384] The number of support screw posts 316, gland threaded holes 324 and first screws 350 can be adjusted according to the actual installation situation. The positions of support screw posts 316 and gland threaded holes 324 are set relative to each other, and the number of support screw posts 316, gland threaded holes 324 and first screws 350 is equal.

[0385] In some embodiments, the elastic member 360 is sleeved on the boss between the support 310 and the pressure cap 320, and a limiting post is provided around the elastic member 360, wherein the elastic member 360 is located between the limiting post and the boss.

[0386] A limiting post facing the other component is provided on one of the two components, support 310 and gland 320.

[0387] In specific implementation, a limiting post facing the pressure cap 320 can be set on the support 310, or a limiting post facing the support 310 can be set on the pressure cap 320, or limiting posts facing each other can be set on both components.

[0388] Taking the setting of a limiting post in the gland 320 as an example, such as Figure 13 and Figure 12 As shown, the pressure cap 320 is provided with a pressure cap boss 321 facing the support 310 and a pressure cap limiting post 325, and the support 310 is provided with a support boss 311 facing the pressure cap 320. The limiting post is arranged around the outer periphery of the pressure cap boss 321 and spaced apart from the pressure cap boss 321. The elastic member 360 is sleeved on the boss and located between the limiting post and the boss.

[0389] The setting of the limiting post and the boss fixes the rotational position of the elastic element 360 in the handle assembly 300, effectively preventing the elastic element 360 from moving in the non-rotational direction.

[0390] In some embodiments, the elastic element 360 is a torsion spring, wherein the shape of the end of the torsion spring matches the shape of the boss.

[0391] For example, the boss is a circular boss, and the torsion spring is a circular torsion spring. The diameter of the torsion spring is slightly larger than the diameter of the boss, so that the torsion spring can be fitted onto the boss.

[0392] like Figure 14As shown, the elastic element 360 has a first leg 361 and a second leg 362. The end of the elastic element 360 is sleeved on the boss. The first leg 361 and the second leg 362 are circumferentially spaced about the axis of rotation of the handle assembly 300.

[0393] A spring-loaded paddle rib 322 is provided on at least one of the support 310 and the pressure cap 320 for actuating the elastic element 360 to rotate, wherein the spring-loaded paddle rib 322 is located between the first support leg 361 and the second support leg 362.

[0394] In specific implementation, spring lever ribs 322 can be set on the support 310, or on the pressure cap 320. Alternatively, spring lever ribs 322 can be set on both the support 310 and the pressure cap 320. When the support 310 and the pressure cap 320 are connected, the two spring lever ribs 322 are joined together to form a complete spring lever rib 322.

[0395] like Figure 12 As shown, a spring-loaded paddle rib 322 is provided on the pressure cover 320. The spring-loaded paddle rib 322 is located between the first leg 361 and the second leg 362 of the elastic member 360. When the handle assembly 300 rotates, the spring-loaded paddle rib 322 on the pressure cover 320 drives the elastic member 360 to rotate.

[0396] When the handle assembly 300 stops rotating, the elastic force generated by the elastic element 360 drives the handle assembly 300 back to its initial position through the spring tab 322.

[0397] like Figure 16 As shown, a spring limiting rib 234 is provided on the faucet assembly 200. The spring limiting rib 234 is located between the first leg 361 and the second leg 362 of the elastic member 360. The spring limiting rib 234 plays a role in stopping and limiting the elastic member 360.

[0398] When the handle assembly 300 rotates, the spring paddle rib 322 stops against one of the pins of the elastic element 360, causing the elastic element 360 to rotate. When one of the pins stops against the spring limiting rib 234, the handle assembly 300 stops rotating due to the limiting effect of the spring limiting rib 234, effectively avoiding damage to the elastic element 360 caused by excessive rotation of the handle assembly 300.

[0399] In some embodiments, such as Figure 16 As shown, the faucet assembly 200 is provided with a support shaft 236, which is a connecting shaft-shaped component used to support the connecting handle assembly 300 and the faucet assembly 200.

[0400] like Figure 13 and 15As shown, support holes 312 and pressure cap holes 323 are provided on the support 310 and pressure cap 320 of the handle assembly 300, opposite to the support shaft 236.

[0401] like Figure 11 As shown, when the faucet assembly 200 and the handle assembly 300 are connected, the support shaft 236 passes through the support hole 312 and the pressure cap hole 323. A support threaded hole can be provided in the center of the support shaft 236. The connection between the faucet assembly 200 and the handle assembly 300 can be achieved by a threaded connector passing through the support hole 312, the pressure cap hole 323 and the support threaded hole.

[0402] It is understandable that, such as Figure 13 and Figure 15 As shown, the support hole 312 and the pressure cap 320 can be set at the center of the support boss 311 and the pressure cap boss 321, which does not affect the installation and torsion of the elastic element 360, and can also save space and reduce the overall volume of the faucet.

[0403] In some embodiments, a mounting position may be provided on the handle assembly 300 for mounting the first sensor 430.

[0404] like Figure 12 As shown, a mounting post 313 can be provided on the support 310 of the handle assembly 300, and a mounting groove 314 is provided at the end of the mounting post 313 near the faucet assembly 200. The mounting groove 314 on the mounting post 313 defines the mounting position.

[0405] It is understandable that the mounting position is spaced apart from the rotation axis of the handle assembly 300, and the mounting position also rotates when the handle assembly 300 rotates around the rotation axis.

[0406] At least a portion of the first sensor 430 is mounted on the mounting position of the support 310, and the first sensor 430 located in the mounting position also rotates when the handle assembly 300 is rotated.

[0407] When the handle assembly 300 drives the first sensor 430 in the mounting position to rotate to the target position, the first sensor 430 generates a first trigger signal, thereby controlling the faucet's water intake and temperature control.

[0408] In some embodiments, the first sensor 430 is a Hall sensor device, including a magnet 431 and a Hall sensor 432.

[0409] like Figure 12 As shown, magnet 431 is mounted on the mounting position of support 310, and Hall sensor is mounted on faucet assembly 200.

[0410] When the user rotates the handle assembly 300 to the target position, the magnet 431 in the handle assembly 300 approaches the Hall sensor 432, and the Hall sensor 432 is triggered by the magnet 431 to generate a current signal, which is the first trigger signal.

[0411] In some embodiments, such as Figure 17 As shown, the Hall sensor 432 located on the faucet assembly 200 can be respectively set on both sides of the rotation direction of the magnet 431.

[0412] When the handle assembly 300 rotates in different directions around the rotation axis, the magnet 431 can approach different Hall sensors 432 respectively, and the different Hall sensors 432 on both sides generate different first trigger signals.

[0413] When the user rotates the handle, it approaches the Hall sensors 432 on both sides in different directions, generating different first trigger signals, which in turn control the faucet's water flow, water temperature, or water volume.

[0414] In some embodiments, such as Figure 11 and Figure 12 As shown, a stop rib 235 is provided on the faucet assembly 200. The stop rib 235 is located above the support shaft 236. A travel limit rib 315 is provided between the mounting post 313 of the support 310 and the support hole 312.

[0415] The travel limit rib 315 on the support 310 and the stop rib 235 on the faucet assembly 200 are distributed at intervals along the axis of rotation of the handle assembly 300.

[0416] When the handle assembly 300 rotates around the support shaft 236 to the target position, the stop rib 235 stops the travel limit rib 315. The travel limit rib 315 is distributed on both sides of the stop rib 235. When the handle assembly 300 rotates around the support shaft 236 in different directions, the stop rib 235 can stop the travel limit rib 315.

[0417] The stop rib 235 and the travel limit rib 315 can limit the rotation of the handle assembly 300 within a certain range, so as to avoid the handle assembly 300 from rotating excessively and the first sensor 430 from failing to generate the first trigger signal.

[0418] In some embodiments, the faucet assembly 200 includes a faucet body 210 and a mounting bracket 230.

[0419] The faucet body 210 is the main part of the faucet. A water pipe and an electric wire can be inserted through the middle of the faucet body 210 to connect to the first sensor 430 for electrical control, so as to control the faucet's water flow, water temperature, or water flow rate.

[0420] likeFigure 11 As shown, the mounting bracket 230 is an important connecting component that connects the handle assembly 300 and the faucet assembly 200. The handle assembly 300 is pivotally mounted on the mounting bracket 230, and the mounting bracket 230 is mounted on the faucet body 210, thereby achieving a stable installation of the handle assembly 300 and the faucet assembly 200.

[0421] like Figure 16 As shown, the mounting bracket 230 is provided with a spring limiting rib 234 and a support shaft 236. The spring limiting rib 234 and the support shaft 236 are provided with a mounting bracket threaded hole 232, and the mounting bracket 230 can be installed on the faucet body 210 by means of threaded connection.

[0422] In some embodiments, a mounting base 220 is provided on the faucet body 210, and the mounting bracket 230 is mounted on the faucet via the mounting base 220 on the faucet body 210.

[0423] In specific implementation, such as Figure 11 As shown, the mounting bracket 230 can be installed on the mounting base 220 by using a threaded connector that passes through the threaded hole 232 of the mounting bracket and the threaded hole 222 of the mounting base.

[0424] A portion of the first sensor 430 is mounted in the mounting base 220, and another portion of the first sensor 430, which is used to generate current information, is mounted on the fabricated mounting post 313.

[0425] Taking the Hall sensor as an example, the magnet 431 is installed in the mounting position of the support 310. When the handle assembly 300 is rotated, the magnet 431 approaches the Hall sensor 432 in the mounting base 220, thereby generating a first trigger signal.

[0426] like Figure 24 As shown, a sensor positioning rib 741 is provided on the outer peripheral wall of the inner core 700. The mounting base 220 is part of the inner core 700. The sensor positioning rib 741 cooperates with the sensor notch 433 provided in the first sensor 430 to realize the fixed installation of the first sensor 430 on the mounting base 220.

[0427] In some embodiments, the mounting base 220 and the mounting bracket 230 are connected by a snap-fit ​​123.

[0428] like Figure 11 As shown, a slot 221 is provided on the mounting base 220, and a positioning rib is provided at the corresponding position on the mounting bracket 230. The mounting bracket 230 can be locked in place by the positioning rib on the mounting bracket 230 and the slot 221 on the mounting base 220, so that the mounting bracket 230 is securely installed on the mounting base 220.

[0429] In practice, the slots 221 of the mounting base 220 can be set on the left and right sides of the mounting base 220, and corresponding positioning ribs are set on the left and right sides of the mounting frame 230. The mounting frame 230 is installed on the mounting base 220 by the positioning ribs on both sides and the slots 221.

[0430] like Figure 1 and Figure 18 As shown, the faucet includes a handle body 500 and a faucet body 210. The faucet body 210 includes a faucet assembly 200 and a water outlet 111. The faucet assembly 200 is installed and fixed together with the faucet body 210 and the handle body 500. The user draws water from the water outlet 111.

[0431] The handle body 500 is the main operating component of the faucet. The handle body 500 is installed on the faucet assembly 200. The handle body 500 can rotate around the faucet assembly 200. In actual operation, the water outlet 111 of the faucet or the water temperature can be adjusted by rotating the handle body 500.

[0432] like Figure 2 As shown, the faucet provided in this embodiment of the invention may further include: a water outlet, a hot water pipe 620, and a normal temperature water pipe 630.

[0433] The water outlet is a cylindrical shell with a hollow cavity inside. The hollow cavity inside is a water outlet cavity 613. The water outlet is provided with a water outlet hole 614, a hot water inlet 615 and a normal temperature water inlet 616.

[0434] The water outlet 614 is connected to the water outlet cavity 613 and is used to allow water to flow out of the water outlet cavity 613. The hot water inlet 615 and the room temperature water inlet 616 are the two water inlets of the faucet, both of which are connected to the water outlet cavity 613 and are used to deliver hot water and room temperature water to the water outlet cavity 613 and then flow out from the water outlet 614 for the user's use.

[0435] In actual implementation, the water outlet 614 can be located at the bottom of the water outlet, and the hot water inlet 615 and the normal temperature water inlet 616 can be located on the peripheral wall of the water outlet for easy access to water.

[0436] In this embodiment, the hot water inlet 615 is connected to one end of the hot water pipe 620, and the other end of the hot water pipe 620 is connected to the hot water source. The hot water pipe 620 is used to transport hot water from the hot water source into the hot water inlet 615.

[0437] Correspondingly, the ambient temperature water inlet 616 is connected to one end of the ambient temperature water pipe 630, and the other end of the ambient temperature water pipe 630 is connected to the ambient temperature water source. The ambient temperature water pipe 630 is used to transport ambient temperature water from the ambient temperature water source into the ambient temperature water inlet 616.

[0438] The hot water source can be water with a temperature above 45 degrees Celsius, while the room temperature water source can be water with a temperature below 45 degrees Celsius. The specific temperature value can also be set according to the user's needs.

[0439] Hot water pipe 620 and normal temperature water pipe 630 can be made of other materials such as galvanized pipe, polyvinyl chloride resin pipe, aluminum-plastic pipe and type 3 polypropylene pipe.

[0440] In related technologies, the faucet spout is only connected to one water inlet pipe. Users need to wait a long time to allow the residual water in the pipe to drain completely before taking hot water or vice versa. Furthermore, taking hot water and then taking room temperature water may result in users being scalded by the residual hot water in the pipe.

[0441] Understandably, the water in the hot water pipe 620 and the room temperature water pipe 630 flows into the water outlet chamber 613 through the hot water inlet 615 and the room temperature water inlet 616, and then flows directly out from the water outlet 614. The water outlet chamber 613 is small in volume and will not retain too much hot or room temperature water. After taking hot water, the user can take room temperature water directly without waiting for a long time and will not be scalded by residual hot water.

[0442] According to the faucet provided by the present invention, by defining a water outlet cavity 613, a water outlet hole 614, a hot water inlet 615, and a room temperature water inlet 616 within the water outlet, water from the hot water pipe 620 and the room temperature water pipe 630 flows into the water outlet cavity 613 through the hot water inlet 615 and the room temperature water inlet 616, and then flows directly out from the water outlet hole 614. The water outlet cavity 613 has a small volume, so it will not retain too much hot water or room temperature water, improving the convenience of water access and effectively preventing users from being scalded.

[0443] In some embodiments, such as Figure 2 As shown, the water outlet includes: a water outlet housing 610 and an aerator 640.

[0444] The inside of the faucet housing 610 is a hollow cavity, which defines the water outlet 614, the hot water inlet 615 and the room temperature water inlet 616, and the appearance is a cylindrical shell.

[0445] The faucet housing 610 has a certain mechanical strength and is corrosion resistant. It can be made of materials such as stainless steel, cast iron, all-plastic, brass, zinc alloy, and polymer composite materials.

[0446] The aerator 640 is installed in the water outlet chamber 613, that is, the aerator 640 is connected to the faucet shell 610. The aerator 640 can be securely connected to the faucet shell 610 by means of threaded connection or snap-fit ​​123.

[0447] The aerator 640 allows the flowing water and air to mix thoroughly, creating a foaming effect, increasing flushing power, thereby reducing water consumption, and also serves to prevent splashing, reduce noise, filter, and maintain a constant water flow.

[0448] In actual operation, the aerator 640 is installed at the water outlet 614 of the water outlet chamber 613, which plays a role in saving water, preventing splashing, reducing noise, filtering and maintaining a constant water flow for the water flowing out of the water outlet 614.

[0449] In some embodiments, such as Figure 2 As shown, a water tap fastener 650 is also installed below the water tap housing 610 and the aerator 640, which serves to secure the water tap housing 610 and the aerator 640.

[0450] The faucet fastener 650 can be fastened to the faucet housing 610 and the aerator 640 by means of threaded connection or snap-fit ​​123.

[0451] like Figure 3 As shown, the inner peripheral wall of the water tap fastener 650 is provided with a first limiting step surface 651, which is away from the water outlet 614 of the water tap shell 610; the inner peripheral wall of the water tap shell 610 is provided with a second limiting step surface 617, which faces the water outlet 614 of the water tap shell 610 and is located above the first limiting step surface 651.

[0452] In this embodiment, the second limiting step surface 617 of the faucet shell 610 is disposed opposite to the first limiting step surface 651 of the faucet fastener 650 to form a clamping structure, which clamps the aerator 640 installed in the faucet shell 610 and improves the stability of the aerator 640.

[0453] like Figure 3 As shown, the lower end of the aerator 640 is tightly connected to the first limiting step surface 651, and the upper end of the aerator 640 is tightly connected to the second limiting step surface 617, and is securely clamped between the first limiting step surface 651 and the second limiting step surface 617.

[0454] It is understandable that by setting the first limiting step surface 651 and the second limiting step surface 617, the aerator 640 can be firmly clamped by the faucet shell 610 and the faucet fastener 650, without the need to set threaded connection parts or buckle 123 parts on the aerator 640 for installation, which facilitates the installation and replacement of the aerator 640.

[0455] In some embodiments, the faucet fastener 650 is sleeved on the outside of the faucet housing 610, and the width of the first limiting step surface 651 of the faucet fastener 650 is greater than the width of the end of the faucet housing 610, thereby providing support and fixing for the faucet housing 610.

[0456] likeFigure 3 As shown, the aerator 640 is installed inside the faucet housing 610. The width of the first limiting step surface 651 is greater than the width of the end of the faucet housing 610. The aerator 640 is supported on the first limiting step surface 651, specifically the part of the first limiting step surface 651 that protrudes from the end of the faucet housing 610.

[0457] That is, the faucet shell 610 is supported on the outer ring of the first limiting step surface 651, and the aerator 640 is supported on the inner ring of the first limiting step surface 651.

[0458] The width of the first limiting step surface 651 on the water tap fastener 650 is greater than the width of the end of the water tap shell 610. It can support and fix the water tap shell 610 while cooperating with the second limiting step surface 617 to firmly clamp the aerator 640.

[0459] In some embodiments, such as Figure 2 As shown, the water tap fastener 650 has an internal thread on its inner peripheral wall, and correspondingly, the water tap housing 610 has an external thread on its outer peripheral wall. The water tap fastener 650 and the water tap housing 610 are securely connected by the threaded connection.

[0460] It is understandable that the internal thread of the water tap fastener 650 and the external thread of the water tap shell 610 are matched in terms of the number of thread turns and the direction of thread rotation. The internal and external threads are connected to achieve the connection between the water tap fastener 650 and the water tap shell 610, thereby providing a stable installation for the aerator 640.

[0461] In some embodiments, such as Figure 2 As shown, the water outlet also includes a water outlet sealing ring 660, which is located between the aerator 640 and the water outlet to prevent leakage caused by pressure, corrosion, and thermal expansion and contraction between the aerator 640 and the water outlet.

[0462] The water outlet sealing ring 660 can be a rubber water outlet sealing ring 660, which has a certain elasticity and anti-corrosion function. It can fully fill the space between the aerator 640 and the water outlet to ensure sealing. It is also elastic and will not cause mechanical damage to the aerator 640 and the water outlet.

[0463] In this embodiment, the water outlet sealing ring 660 is clamped between the second limiting step surface 617 of the water outlet shell 610 and the upper end of the aerator 640, and abuts against the aerator 640 and the water outlet.

[0464] Understandably, the width of the spout sealing ring 660 can be equal to the width of the second limiting step surface 617, further improving the sealing between the aerator 640 and the spout.

[0465] In some embodiments, the faucet housing 610 is installed at one end of the faucet upper housing 100, and the hot water pipe 620 and the room temperature water pipe 630 are installed inside the upper housing 100.

[0466] The upper shell 100 is a hollow cavity structure. The faucet shell 610 is installed at one end of the upper shell 100 of the faucet. An opening is provided at this end, which is connected to the water outlet 614 of the faucet shell 610. The user draws water from the water outlet 614.

[0467] Hot water pipe 620 and room temperature water pipe 630 are installed in the cavity structure of upper shell 100. Hot water pipe 620 and room temperature water pipe 630 can be placed horizontally in the cavity of upper shell 100 to facilitate connection with hot water inlet 615 and room temperature water inlet 616 on water tap shell 610.

[0468] In some embodiments, the faucet housing 610 includes a faucet housing 611 and a faucet housing cover 612.

[0469] The faucet housing 611 is the main body of the faucet housing 610. The faucet housing 611 defines a water outlet cavity 613. The faucet housing 611 is provided with a water outlet hole 614, a hot water inlet 615 and a normal temperature water inlet 616.

[0470] The faucet cover 612 is the upper cover part of the faucet cover 610, located above the faucet cover 611 and connected to the faucet cover 611. The radius of the faucet cover 612 is larger than the radius of the faucet cover 611. When the faucet cover 612 is installed above the faucet cover 611, it protrudes outward at least partially relative to the faucet cover 611.

[0471] The upper shell 100 is provided with a water tap housing 610 mounting hole. The water tap housing 611 extends into and passes through the water tap housing 610 mounting hole, thereby realizing the installation of the water tap housing 611 on the upper shell 100.

[0472] After the faucet housing 611 is installed on the upper housing 100, the faucet housing cover 612 is installed on top of the faucet housing 611. The radius of the faucet housing cover 612 is larger than the radius of the faucet housing 611. At this time, the faucet housing cover 612 protrudes outward in the radial direction at least partially relative to the mounting hole of the faucet housing 610.

[0473] The faucet housing 611 passes through the faucet housing 610 mounting hole in the upper housing 100, and the faucet housing cover 612 is installed on top of the faucet housing 611 to facilitate the installation and maintenance of the faucet housing 610.

[0474] In some embodiments, such as Figure 3 As shown, the upper shell 100 is provided with a third limiting step surface 618, and the outer peripheral wall of the water nozzle shell 611 is provided with a fourth limiting step surface 619.

[0475] In this embodiment, the third limiting step surface 618 is provided in the water tap shell 610 mounting hole of the upper shell 100, and the inner peripheral wall of the water tap shell 610 mounting hole protrudes inward to form the third limiting step surface 618.

[0476] The outer peripheral wall of the faucet housing 611 is provided with a fourth limiting step surface 619 that supports the third limiting step surface 618. When the faucet housing 611 passes through the mounting hole of the faucet housing 610, the fourth limiting step surface 619 supports the third limiting step surface 618, ensuring the stable installation of the faucet housing 611 on the upper shell 100.

[0477] By utilizing the structure of the upper shell 100 and the faucet shell 611, the third limiting step surface 618 and the fourth limiting step surface 619 are formed, eliminating the need for external connecting parts. This enables the faucet shell 611 and the upper shell 100 to be stably installed, facilitating the installation and maintenance of the faucet shell 611 and reducing the production cost of the faucet.

[0478] Understandably, the width of the third limiting step surface 618 can be slightly larger than the width of the fourth limiting step surface 619 to ensure that the third limiting step surface 618 is fully supported by the fourth limiting step surface 619 without any suspended parts, thereby further improving the installation stability of the water nozzle housing 611.

[0479] In some embodiments, a pipe limiting buckle 670 is also installed inside the cavity of the upper shell 100. The pipe limiting buckle 670 is used to fix the hot water pipe 620 and the normal temperature water pipe 630 installed inside the cavity of the upper shell 100.

[0480] The pipe limiting buckle 670 is provided with a water pipe limiting groove. The hot water pipe 620 and the normal temperature water pipe 630 pass through the water pipe limiting groove. The pipe limiting buckle 670 is connected to the upper shell 100, thereby fixing the hot water pipe 620 and the normal temperature water pipe 630 inside the upper shell 100.

[0481] The water pipe limiting groove can be an unclosed circular limiting groove, the diameter of which matches the diameter of the hot water pipe 620 and the normal temperature water pipe 630. The hot water pipe 620 and the normal temperature water pipe 630 can be installed from the water pipe limiting groove and clamped.

[0482] In actual implementation, the water pipe limiting groove on the pipe limiting buckle 670 is used to fix the hot water pipe 620 and the normal temperature water pipe 630 respectively. The diameter of the water pipe limiting groove is set according to the diameter of the corresponding hot water pipe 620 and normal temperature water pipe 630.

[0483] The pipe limit buckle 670 can be securely connected to the upper shell 100 by means of threaded connection or snap buckle 123.

[0484] You can first pass the hot water pipe 620 and the normal temperature water pipe 630 through the pipe limiting buckle 670, and then connect the pipe limiting buckle 670 to the upper shell 100; or you can first securely connect the pipe limiting buckle 670 to the upper shell 100, and then pass the hot water pipe 620 and the normal temperature water pipe 630 through the pipe limiting buckle 670. Both methods can achieve a secure installation of the hot water pipe 620 and the normal temperature water pipe 630 inside the upper shell 100.

[0485] In some embodiments, such as Figure 4 As shown, the pipe limit buckle 670 includes: a base 671 and two claws 673.

[0486] The base 671 is the mounting part for the pipe limit buckle 670 and the upper shell 100. By setting corresponding connecting holes or connecting buckles on the base 671, the pipe limit buckle 670 and the upper shell 100 are fastened together.

[0487] Taking the connection between the pipe limit buckle 670 and the upper shell 100 via a threaded connector as an example.

[0488] Mounting holes for base 671 are provided on both sides of base 671. During installation, threaded connectors are inserted through the mounting holes of base 671 and installed with the corresponding mounting holes in upper shell 100 or other mounting components.

[0489] The clamping arm 672 extends from the top of the base 671 to both sides to clamp two claws 673. The clamping arm 672 extends to form an unclosed circular clamping groove, the diameter of which is set according to the diameter of the corresponding clamping claw 673.

[0490] In this embodiment, the base 671 can be a three-dimensional T-shaped support, with the horizontal part used to connect with the upper shell 100, and the clamping arm 672 extending outward from the vertical part of the base 671 in a circular trajectory, and is not closed.

[0491] The central portion of the two claws 673 defines the outlet pipe limiting groove for fixing the hot water pipe 620 and the normal temperature water pipe 630.

[0492] Understandably, the two claws 673 respectively fix the hot water pipe 620 and the normal temperature water pipe 630. The pipe limiting buckle 670 formed by the claws 673 and the base 671 can fix the hot water pipe 620 and the normal temperature water pipe 630 inside the upper shell 100. The claws 673 and the base 671 are detachably connected together, which facilitates the maintenance of the pipe limiting buckle 670, the hot water pipe 620 and the normal temperature water pipe 630.

[0493] In some embodiments, such as Figure 4 As shown, the chuck 673 includes a support ring 675 and multiple chuck bodies 676.

[0494] Multiple claw bodies 676 are connected to the support ring 675. The multiple claw bodies 676 extend outward from the end face of the support ring 675 and are spaced apart along the circumference of the support ring 675.

[0495] A limiting boss 677 is provided on the outer side wall of the claw body 676. The claw 673 is installed on the base 671 to form a pipe limiting buckle 670. The limiting boss 677 and the support ring 675 of the claw body 676 are located on both sides of the clamping arm 672. The clamping arm 672 is clamped between the limiting boss 677 and the support ring 675.

[0496] A clamping protrusion 674 is provided on the inner side wall of the claw body 676. The clamping protrusion 674 can lock the hot water pipe 620 and the normal temperature water pipe 630 through the main penetrating claw 673.

[0497] Understandably, the clamping protrusion 674 has a certain directionality, which facilitates the through-installation of the hot water pipe 620 and the normal temperature water pipe 630 in the clamp 673. When the water pipe is inserted from one side of the clamp 673, the clamping protrusion 674 guides the inserted water pipe. When the water pipe is pulled out from the other side of the clamp 673, the clamping protrusion 674 will hold the water pipe in place, so that the water pipe will not be easily pulled out, thus improving the stability of the water pipe within the upper shell 100.
