Abstract
Description
Technical Field
[0001] The utility model belongs to the field of faucets, in particular to a faucet device and a water purifier. Background Art
[0002] When using a faucet to collect water, users may handle other things while waiting for the container to be filled with water, and fail to close the faucet in time, resulting in continuous overflow. This situation not only wastes water resources, but may also damage furniture and soak the floor.
[0003] Most current technologies use the method of continuously pressing a button to collect water or timed and quantitative water collection to prevent excessive overflow. Among them, the method of continuously pressing a button to collect water requires the entire process to rely on user operation, and the method of timed and quantitative water collection also requires the user to adjust parameters according to the amount of water collected. These methods are not completely free from manual control and do not fundamentally solve the overflow problem. Utility Model Content

[0051] An embodiment of the present application provides a faucet device. Figure 1 This is a schematic diagram of a faucet device provided in an embodiment of the present application. Figure 1 ,like Figure 1 As shown, the faucet device includes a faucet 1, an infrared sensor unit 2 and a control unit 3. The faucet 1 and the infrared sensor unit 2 are electrically connected to the control unit 3 respectively. The control unit 3 is used to obtain the container height and the liquid level height through the infrared sensor unit 2, and control the faucet 1 to discharge water or stop discharging water based on the container height and the liquid level height. The container height is the height of the container 4 placed under the faucet 1, and the liquid level height is the height of the solution contained in the container.
[0052] In the embodiment of the present application, the infrared sensor unit 2 obtains the container height and the liquid level height, and controls the faucet 1 to discharge water or stop discharging water based on the container height and the liquid level height, so that the faucet 1 device is completely free from manual control, realizes full-automatic water switching, and fundamentally solves the overflow problem. Moreover, the faucet device is suitable for various containers 4.
[0053] Figure 2 This is a schematic diagram of a faucet device provided in an embodiment of the present application. Figure 2 ,like Figure 2 As shown, the infrared sensing unit 2 includes an infrared sensor 21, a guide rail 22 and a motor 23. The guide rail 22 is located on the faucet 1, the infrared sensor 21 is movably arranged on the guide rail 22, and the motor 23 is connected to the infrared sensor 21. The motor 23 can drive the infrared sensor 21 to move along the guide rail 22.
[0054] In the embodiment of the present application, the control unit 3 is electrically connected to the motor 23. After detecting the container 4 placed on the water receiving platform, the control unit 3 can control the motor 23 to drive the infrared sensor 21 to move along the guide rail 22 from the initial position, and obtain the height of the container during the movement of the infrared sensor 21. The control unit 3 can also control the motor 23 to stop driving the infrared sensor 21 to move when the infrared sensor 21 returns to the initial position, and obtain the liquid level through the infrared sensor 21 stopped at the initial position. The initial position is located directly above the faucet 1.
[0055] In the embodiment of the present application, the infrared sensor 21 uses the propagation and reflection characteristics of infrared rays to measure the distance of an object. The infrared sensor 21 can emit infrared rays of a specific frequency to the location of the target object, and receive the infrared rays reflected back after the infrared rays contact the target object. Based on the time difference between the emission time and the reception time of the infrared rays and the propagation speed of the infrared rays (the speed of light), the distance between the infrared sensor 21 and the target object can be calculated.
[0056] In some possible embodiments, the infrared sensor 21 includes an infrared transmitting module, an infrared receiving module and a data processing module. The infrared transmitting module is used to transmit a first infrared signal to the target object, the infrared receiving module is used to receive a second infrared signal reflected after the first infrared signal contacts the target object, and the data processing module is used to obtain the distance between the infrared sensor 21 and the target object based on the difference between the transmission time of the first infrared signal and the reception time of the second infrared signal.
[0057] In the embodiment of the present application, the first distance H1 from the infrared sensor 21 to the water receiving platform, the second distance H2 from the infrared sensor to the top of the container, and the third distance H3 from the infrared sensor to the liquid surface of the solution can be obtained by the infrared sensor unit 2. Among them, the difference between the first distance H1 and the second distance H2 is the height of the container, and the difference between the first distance H1 and the third distance H3 is the liquid surface height.
[0058] In some possible embodiments, before placing the container 4 on the water receiving platform, the infrared sensor 21 is used to measure a first distance H1 from the infrared sensor 21 to the water receiving platform.
[0059] Optionally, the control unit 3 may save the first distance H1 into a database for subsequent use.
[0060] In the embodiment of the present application, the infrared sensing unit 2 will continuously emit infrared rays to the water receiving platform. After the container 4 is placed on the water receiving platform, the container 4 blocks the infrared rays, thereby triggering the control unit 3 to execute a scanning procedure. In the scanning procedure, the control unit 3 controls the motor 23 to drive the infrared sensor 21 to move along the guide rail 22 from the initial position, and controls the infrared sensor 21 to stop at the initial position. In the process of the infrared sensor 21 moving from the initial position and returning to the initial position, the infrared sensor 21 can obtain multiple distance values corresponding to different target objects, where the target object corresponding to the minimum distance value is the vertex of the container 4. The distance from the infrared sensor 21 to the vertex of the container 4 is the second distance H2. The difference between the first distance H1 and the second distance H2 is the container height.
[0061] Optionally, considering that the initial position of the infrared sensor 21 is not located at the two ends of the guide rail 22, in order to ensure that the target object corresponding to the smallest distance value among the multiple distance values is the vertex of the container 4, the control unit 3 controls the motor 23 to drive the infrared sensor 21 to move back and forth along the guide rail 22 for one circle, that is, the infrared sensor 21 first moves from the initial position to one end of the guide rail 22, then returns to one end of the guide rail 22, and finally returns to the initial position.
[0062] In some possible embodiments, when the infrared sensor 21 stops moving, the control unit 3 controls the faucet 1 to start discharging water.
[0063] Optionally, under the condition that the water volume received by the container 4 before the infrared sensor 21 stops moving is lower than the expected water volume, the control unit 3 can control the faucet 1 to start discharging water at any time after the container 4 is placed on the water receiving station.
[0064] In the embodiment of the present application, after the infrared sensor 21 returns to the initial position, the control unit 3 controls the infrared sensor 21 to measure the third distance H3 from the infrared sensor 21 to the liquid surface in real time. The difference between the first distance H1 and the third distance H3 is the liquid surface height.
[0065] In some possible embodiments, based on the first distance H1, the second distance H2, and the third distance H3, the control unit 3 controls the faucet 1 to continue to discharge water or stop discharging water. When the difference between the height of the container and the height of the liquid level is greater than or equal to the preset distance, the control unit 3 controls the faucet 1 to continue to discharge water. When the difference between the height of the container and the height of the liquid level is less than the preset distance, the control unit 3 controls the faucet 1 to stop discharging water.
[0066] Optionally, the user can set and change the value of the preset distance according to personal needs.
[0067] In some possible embodiments, based on the second distance H2 and the third distance H3, the control unit 3 controls the faucet 1 to continue discharging water or stop discharging water. When the difference between the third distance H3 and the second distance H2 is less than the target distance, the control unit 3 controls the faucet 1 to stop discharging water.
[0068] Optionally, the user can set and change the value of the target distance according to personal needs.
[0069] In some possible embodiments, the control unit 3 includes a control panel. The control panel includes at least one preset distance gear. At least one preset distance gear is an adjustable preset distance gear. When the user uses the container 4 to collect water, he can select one of the preset distance gears according to the required water consumption, and can also adjust the preset distance value of the preset distance gear.
[0070] In some possible embodiments, the faucet 1 includes a switch valve. The switch valve is electrically connected to the control unit 3, and the control unit 3 can control the switch valve to open or close the faucet 1.
[0071] Optionally, the control unit 3 can control the flow rate of water according to the opening degree of the switch valve.
[0072] In some possible embodiments, the control unit 3 includes a reminder device, which is used to send a reminder signal when the faucet 1 stops discharging water.
[0073] Optionally, the reminder signal may be in the form of an indicator light or a voice reminder.
[0074] In some possible embodiments, the faucet device further includes a container scanning unit and a timer. The container scanning unit is used to scan the shape of the container 4 and obtain multiple container width values and multiple container height values from the bottom end of the container 4 to the top end of the container. The multiple container width values and the multiple container height values correspond to each other one by one, and the multiple container height values include a first container height value. The timer is used to measure the first time when the liquid level reaches the first container height value, and the water discharge time of the faucet 1.
[0075] Optionally, the container width value refers to the width value of the water-holding portion inside the container 4 .
[0076] In some possible embodiments, the container scanning unit and the timer are respectively electrically connected to the control unit 3. The control unit 3 is used to calculate the preset time according to multiple container width values, multiple container height values and the first time, and control the sensor unit to obtain the liquid level when the water discharge time reaches the preset time.
[0077] In some possible embodiments, the first time when the liquid level reaches the first container height value is obtained by a timer, and the shape of the container 4 is determined by a container scanning unit. The control unit 3 calculates the time required for the liquid level to reach the expected container height according to the first time and the container shape, and sets a preset time according to this time. By adding a container scanning unit and a timer to the faucet device, the infrared sensor 21 can be used to obtain the liquid level only at the beginning and end of the water discharge of the faucet 1. This faucet device is suitable for large containers 4.
[0078] In some possible embodiments, the faucet 1 includes a water spout and a connecting pipe, one end of the connecting pipe is connected to the water spout, and the other end of the connecting pipe is connected to a water storage tank or a water supply pipeline.
[0079] Optionally, when the faucet device is applied to a water dispenser or a water purifier, the other end of the connecting pipe can be connected to a water storage tank.
[0080] Optionally, when the faucet device is applied to a sink in a kitchen or bathroom, the other end of the connecting pipe can be connected to a water supply pipeline.
[0081] In the embodiment of the present application, when the container 4 is placed on the water receiving platform, the control unit 3 controls the motor 23 to drive the infrared sensor 21 to move back and forth along the guide rail 22 for one circle, thereby obtaining the height of the container. When the infrared sensor 21 returns to the top of the faucet 1, the control unit 3 controls the infrared sensor 21 to continue to measure the liquid level in real time. Based on the container height and the liquid level, the control unit 3 controls the faucet 1 to discharge water or stop discharging water, thereby completely freeing the faucet device from manual control, realizing fully automatic water on and off, and fundamentally solving the overflow problem.
