Description
Technical Field
[0001] The utility model relates to the technical field of faucets, in particular to a faucet structure. Background Art
[0002] Faucets are essential facilities in life. After water flows out of the faucet, it is easy to splash. To solve this problem, the Chinese utility model patent No. CN201420393278.5 (Announcement No. CN204004774U) discloses a faucet diversion device, which includes a first gasket and a second gasket made of silicone material, and the first gasket and the second gasket are sewn together at the top, and an interlayer space for gauze to be sandwiched is formed between the first gasket and the second gasket. The two gaskets are sewn with Velcro that can be bonded to each other on the inner surface of one side and the outer surface of the other side; gauze is sandwiched between the interlayer space of the first gasket and the second gasket, and the lower hem of the gauze is exposed. With the first gasket as the inner surface, the first gasket and the second gasket are surrounded on the round tube of the faucet outlet, and the first gasket and the second gasket are tightened with Velcro; the faucet diversion device can tie the gauze to the faucet outlet, and when the faucet is turned on, the gauze can absorb the water splashing outward and rectify it downward.
[0003] Although this patent can solve the problem of water splashing, if the length of the guide device is short, when the water flows out of the faucet, it falls into the water receiving container below the faucet outlet. Due to the high height of the water falling, it is easy to cause loud noise in the water receiving container. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a faucet structure capable of preventing water splashing and loud noise in view of the current status of the prior art.
[0005] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a faucet structure, including a faucet and a vertically extending drainage rod, characterized in that the faucet is provided with a mounting tube, the mounting tube is located above the water outlet of the faucet, the drainage rod can be installed in the mounting tube so as to be movable up and down, and the drainage rod can move to a position on the water outlet path of the water outlet.
[0006] Preferably, the bottom of the installation tube is open and located just above the water outlet of the faucet, and the drainage rod can move upward to a position where the lower end is located in the installation tube or in the faucet. When the faucet does not discharge water, the drainage rod is hidden in the installation tube and the faucet, so as to prevent the drainage rod from being contaminated and affecting the water quality, and to facilitate the removal of the water receiving container, otherwise the drainage rod is partially located in the water receiving container, which will interfere with the movement of the water receiving container.
[0007] Preferably, the top of the mounting tube is closed to prevent water from splashing out from the top of the mounting tube, and the top wall of the mounting tube can also limit the upward movement of the drainage rod.
[0008] Preferably, the faucet structure further comprises a driving mechanism for driving the drainage rod to move up and down.
[0009] The driving mechanism can have a variety of structural forms, such as a push rod motor, which directly pushes the drainage rod up and down, but the push rod motor is not convenient to be set in the mounting tube, so the driving mechanism includes a motor and a rotating shaft connected to the motor drive, the rotating shaft can rotate forward or reverse around its axis, the axis of the rotating shaft is perpendicular to the axis of the drainage rod, the rotating shaft is a flexible member, and the peripheral wall of the mounting tube is provided with a receiving groove for the rotating shaft to be accommodated therein, and the outer wall surface of the rotating shaft is in contact with the drainage rod. When the rotating shaft is in a rotating state, the friction between the rotating shaft and the drainage rod must be able to drive the drainage rod to move up and down, and when the rotating shaft is in a stationary state, the friction between the rotating shaft and the drainage rod must be able to position the drainage rod. In this way, the motor can be set outside the mounting tube, and the rotating shaft is set in the peripheral wall of the mounting tube, and the driving mechanism will not occupy the space in the mounting tube, which is convenient for setting.
[0010] In order to enable the motor to drive the rotating shaft to rotate, the motor is connected to the rotating shaft through a transmission structure, and the transmission structure includes a first gear and a second gear that are meshed with each other. The first gear is connected to the motor, and the second gear is fixedly connected to the rotating shaft and the two are coaxially arranged.
[0011] In order to automatically control the lifting and lowering of the drainage rod, the faucet structure also includes a controller and a sensor for sensing the relative position of the drainage rod and the water receiving container, the sensor is electrically connected to the input end of the controller, and the driving mechanism is electrically connected to the output end of the controller. The sensor sends the detected position information of the drainage rod to the controller, and the controller determines whether the position of the drainage rod reaches the set value based on the received signal and adjusts the height of the drainage rod.
[0012] Preferably, the faucet structure further includes a switch for controlling the opening or closing of the faucet, and the switch is electrically connected to the input end of the controller. When the faucet is turned on, a signal is sent to the controller, and the controller controls the driving mechanism to operate so that the drainage rod moves downward. During the downward movement, the sensor detects the position of the drainage rod and sends a signal to the controller. The controller controls the driving mechanism to make the drainage rod hover at an appropriate position, such as the distance between the bottom wall of the drainage rod and the bottom wall of the water receiving container is between 0 and 100 mm; when the faucet is closed, a signal is sent to the controller, and the controller controls the driving mechanism to operate so that the drainage rod moves upward.
[0013] In order to prevent the drainage rod from moving too far downward and interfering with the bottom wall of the water receiving container, a sensor for sensing the relative position of the drainage rod and the water receiving container is also provided on the drainage rod.
[0014] Preferably, the sensor is a position sensor, which is arranged at the bottom of the drainage rod so as to be movable up and down, and an elastic member is also provided on the drainage rod, and the sensor maintains a tendency to move downward under the action of the elastic member. When the position sensor touches the bottom wall of the water receiving container, the motor stops working and rotates in the opposite direction to drive the drainage rod upward by a certain distance, such as between 0 and 100 mm. Because the elastic member is connected to the position sensor, the position sensor and the bottom wall of the water receiving container are in elastic contact, and no hard interference will occur to cause damage to the components.
[0015] Preferably, the bottom of the drainage rod is provided with a groove penetrating the bottom wall thereof, the sensor and the elastic member are both provided in the groove, and the sensor maintains a tendency of the lower end being exposed from the groove under the action of the elastic member. Because of the effect of pressure, water will not enter the groove, so the sensor of this solution does not need to worry about water entering the sensor, similar to the principle that water will not enter the water cup when a water cup is turned upside down on the water surface and then pressed down.
[0016] In the above solution, the elastic member is a spring extending vertically, the upper end of which is fixedly connected to the top wall surface of the groove, and the lower end of which is fixedly connected to the top of the position sensor.
[0017] Preferably, the sensor is an ultrasonic sensor, which is arranged on the faucet. The ultrasonic sensor can detect the water surface or bottom wall of the water receiving container, and can suspend the drainage rod at a certain distance (such as 30 mm) from the bottom wall of the water receiving container. This is more convenient than the position sensor, and there is no need to raise the drainage rod after the sensor touches the bottom wall of the water receiving container; in addition, the ultrasonic sensor can measure distance in a non-contact manner, and the ultrasonic sensor is arranged on the mounting tube, which can solve the problem of sensor waterproofing.
[0018] Compared with the prior art, the utility model has the following advantages: the utility model provides a drainage rod on the faucet, and the drainage rod can be moved to a position on the water outlet path of the water outlet. After the water flows out of the faucet, it will flow downward along the peripheral wall of the drainage rod by utilizing the Coanda effect, thereby reducing the splashing problem when the water flows downward. Moreover, because the drainage rod can move up and down, the drainage rod can be moved to a position where its lower end is closer to the bottom wall of the water receiving container, thereby reducing the noise of the water falling into the water receiving container.

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] Example 1
[0026] like Figures 1 to 4 As shown, the faucet structure of this preferred embodiment includes a faucet 1, a drainage rod 2, a driving mechanism 3 and a sensor.
[0027] A mounting tube 4 is provided on the faucet 1, the bottom of the mounting tube 4 is open and is located directly above the water outlet 11 of the faucet 1, the drainage rod 2 extends vertically, and the drainage rod 2 is installed in the mounting tube 4 so as to be movable up and down, the drainage rod 2 can move to a position on the water outlet path of the water outlet 11, and the drainage rod 2 can move upward to a position where the lower end is located in the mounting tube 4 or in the faucet 1.
[0028] When water flows out of the faucet 1, the drainage rod 2 moves to a position on the water outlet path of the water outlet 11. After the water flows out of the faucet 1, it will flow downward along the peripheral wall of the drainage rod 2 by utilizing the Coanda effect, thereby reducing the splashing problem when the water flows downward. Moreover, because the drainage rod 2 can move up and down, the drainage rod 2 can be moved to a position where its lower end is closer to the bottom wall of the water receiving container, thereby reducing the noise of the water falling into the water receiving container.
[0029] When the faucet 1 does not produce water, the drainage rod 2 is hidden in the installation tube 4 and the faucet 1. This can prevent the drainage rod 2 from being contaminated and affecting the water quality. It can also facilitate the removal of the water receiving container. Otherwise, the drainage rod 2 is partially located in the water receiving container, which will interfere with the movement of the water receiving container.
[0030] The top of the installation tube 4 is closed to prevent water from splashing out from the top of the installation tube 4 . At the same time, the top wall of the installation tube 4 can also limit the upward movement of the drainage rod 2 .
[0031] The driving mechanism 3 is used to drive the drainage rod 2 to move up and down. In this embodiment, the driving mechanism 3 includes a motor 31 and a rotating shaft 32 connected to the motor 31 through a transmission structure. The rotating shaft 32 can rotate forward or reverse around its axis. The axis of the rotating shaft 32 is perpendicular to the axis of the drainage rod 2. The rotating shaft 32 is a flexible member. The peripheral wall of the mounting tube 4 is provided with a receiving groove 41 in which the rotating shaft 32 can be accommodated, and the outer wall surface of the rotating shaft 32 is in contact with the drainage rod 2. When the rotating shaft 32 is in a rotating state, the friction between the rotating shaft 32 and the drainage rod 2 needs to be able to drive the drainage rod 2 to move up and down. When the rotating shaft 32 is in a stationary state, the friction between the rotating shaft 32 and the drainage rod 2 needs to be able to position the drainage rod 2. The rotating shaft 32 can be a rubber member. In this way, the motor 31 can be set outside the mounting tube 4, and the rotating shaft 32 is set in the peripheral wall of the mounting tube 4. The driving mechanism 3 will not occupy the space in the mounting tube 4, which is convenient for setting.
[0032] The transmission structure includes a first gear (not shown in the figure) and a second gear 33 that are meshed with each other. The first gear is connected to the motor 31, and the second gear 33 is fixedly connected to the rotating shaft 32 and the two are coaxially arranged.
[0033] The sensor is used to sense the relative position of the drainage rod 2 and the water receiving container. The faucet structure also includes a controller and a switch for controlling the faucet 1 to be turned on or off. The sensor is electrically connected to the input end of the controller, the drive mechanism 3 is electrically connected to the output end of the controller, and the switch is electrically connected to the input end of the controller. The electrical connection between the components can adopt the existing technology, and the switch structure can also adopt the existing technology, which will not be repeated here.
[0034] When the faucet 1 is turned on, a signal is sent to the controller, and the controller controls the driving mechanism 3 to work, so that the drainage rod 2 moves downward. During the downward movement, the sensor detects the position of the drainage rod 2 and sends a signal to the controller. The controller controls the driving mechanism 3 to make the drainage rod 2 hover at an appropriate position, for example, the bottom wall of the drainage rod 2 is between 0 and 100 mm from the bottom wall of the water receiving container; when the faucet 1 is closed, a signal is sent to the controller, and the controller controls the driving mechanism 3 to work, so that the drainage rod 2 moves upward.
[0035] In this embodiment, the sensor is a position sensor 5. The bottom of the drainage rod 2 is provided with a groove 21 penetrating the bottom wall thereof. The position sensor 5 is arranged in the groove 21 so as to be movable up and down. An elastic member 51 is arranged in the groove 21. Under the action of the elastic member 51, the sensor keeps moving downward and the lower end is exposed from the groove 21. When the position sensor 5 touches the bottom wall of the water receiving container, the motor 31 stops working and rotates in the opposite direction to drive the drainage rod 2 upward by a certain distance, for example, so that the bottom wall of the drainage rod 2 is between 0 and 100 mm from the bottom wall of the water receiving container. Because the elastic member 51 is connected to the position sensor 5, the position sensor 5 is in elastic contact with the bottom wall of the water receiving container, and no hard interference will be generated to cause damage to the components.
[0036] Because of the effect of pressure, water will not enter the groove 21, so the sensor of this solution does not need to worry about the problem of water entering the sensor, which is similar to the principle that when a cup is turned upside down on the water surface and then pressed down, water will not enter the cup.
[0037] The elastic member 51 is a spring extending vertically, with an upper end fixedly connected to the top wall surface of the groove 21 and a lower end fixedly connected to the top of the position sensor 5 .
[0038] Example 2
[0039] like Figure 5 As shown, the difference between Example 2 and Example 1 is:
[0040] The sensor of this embodiment is an ultrasonic sensor 6, which is arranged on the faucet 1. The ultrasonic sensor 6 can detect the water surface or the bottom wall of the water receiving container, and can suspend the drainage rod 2 at a position where its bottom wall is a certain distance (for example, 30 mm) from the bottom wall of the water receiving container. This is more convenient than the position sensor 5, and there is no need to raise the drainage rod 2 after the sensor touches the bottom wall of the water receiving container; in addition, the ultrasonic sensor 6 can measure distance in a non-contact manner, and the ultrasonic sensor 6 is arranged on the mounting tube 4, which can solve the problem of sensor waterproofing.
