DETAILED DESCRIPTION

[0039] The following combination Figure 1-13 The present invention will be described in detail.

[0040] This embodiment provides a water outlet device 10, which includes a water inlet channel, a water outlet channel 1013, and a flow channel 1014 connected to the water inlet channel and the water outlet channel 1013, and further includes:

[0041] The first water outlet device 20 is provided with a water inlet cavity connected to the water inlet channel, a water outlet cavity connected to the water outlet channel 1013, and a switching member for controlling whether the water inlet cavity is connected to the water outlet cavity;

[0042] A second water outlet device includes a circuit board 30, and a switch valve 40 and a flow sensor 50 connected to the circuit board 30. The switch valve 40 is used to open or close the flow channel 1014 to control whether the water outlet channel 1013 is connected to the water inlet channel. The sensing end of the flow sensor 50 is located in the water outlet channel 1013 or the flow channel 1014 to measure the current water output. When the water output reaches a preset value, the circuit board 30 closes the switch valve 40; and

[0043] The handle 70 is connected to the switching member and is provided with a first rotation axis 701 and a second rotation axis 702 perpendicular to each other. The handle 70 is connected to the switching member, and the first rotation axis 701 is coaxially arranged with the rotation axis of the switching member.

[0044] Therefore, when the handle 70 rotates around the first rotation axis 701, it drives the switching member to form a first switch to open and close the first water outlet device 20, and when the handle 70 rotates around the second rotation axis 702, it also constitutes a second switch to trigger the circuit board 30 to open the switch valve 40 and the flow sensor 50.

[0045] In summary, the water outlet device 10 proposed in this embodiment includes a first water outlet device 20 for manual water outlet and a second water outlet device for automatic quantitative water outlet. During use, by changing the movement posture of the handle 70, it respectively forms a first switch for driving the first water outlet device 20 and a second switch for driving the second water outlet device. This avoids the need for two handles 70 to separately drive the first water outlet device 20 and the second water outlet device, achieving manual and automatic quantitative water outlet, thereby reducing product size and improving user experience.

[0046] In this embodiment, Figure 12 、 Figure 13 As shown, the circuit board 30 is provided with a first quantitative switch 601 and a second quantitative switch 602 for respectively starting the switch valve 40, and the swing handle 70 triggers the first quantitative switch 601 and the second quantitative switch 602 respectively. The circuit board 30 is provided with a first water output program and a second water output program respectively cooperating with the first quantitative switch 601 and the second quantitative switch 602.

[0047] In this embodiment, Figure 4 As shown, the water inlet channel includes a hot water channel 1011 and a cold water channel 1012, and the other end of the flow channel 1014 is connected to the cold water channel 1012. In other embodiments, the other end of the flow channel 1014 is connected to the hot water channel 1011. The water inlet chamber includes a cold water chamber connected to the cold water channel 1012 and a hot water chamber connected to the hot water channel 1011, and the switching element has a first state in which neither the cold water chamber nor the hot water chamber is connected to the water outlet chamber, a second state in which both the cold water chamber and the hot water chamber are connected to the water outlet chamber, and a third state in which either the cold water chamber or the hot water chamber is connected to the water outlet chamber. Therefore, the first water outlet device 20 can adopt a common mixing valve, whose valve stem 201 constitutes the switching element, and water outlet and water temperature adjustment are achieved by rotating the valve stem 201.

[0048] In this embodiment, the handle 70 is driven to rotate around the first rotation axis 701, so that the handle 70 drives the switching element to rotate, so that the switching element switches between the first state, the second state and the third state, thereby realizing the manual water discharge function. Figure 9As shown, when the handle 70 is in position A, the switching element is in the first state. Rotating the handle 70 about the first rotation axis 701 from position A to position B drives the switching element to the second state. Continuing to rotate the handle 70 until it can no longer rotate, it moves from position B to position C, driving the switching element to the third state. The rotation angle of the handle 70 is the angle α corresponding to the transition from position A to position C, and position B is any position between positions A and C.

[0049] In this embodiment, when the switch is in the first state, the handle 70 can trigger the first quantitative switch 601 and the second quantitative switch 602 to realize the automatic quantitative water discharge function. Figure 12 As shown, by pressing the handle body 801 inward to rotate it by B1 degrees, the handle 70 triggers the first quantitative switch 601, and the circuit board 30 controls the switch valve 40 to open the flow channel 1014, and cold water flows out. The flow sensor 50 counts the current water output; when the water output reaches the water output set in the first water output program, the circuit board 30 controls the switch valve 40 to close the flow channel 1014, realizing automatic quantitative water output. Figure 13 As shown, pressing the handle body 801 outward to rotate it B2 degrees triggers the second quantitative switch 602. The water dispensing process is the same and will not be described in detail. The first water output program and the second water output program are usually set to two water outputs. Specifically, the first water output program is 500 ml and the second water output program is 1000 ml. During subsequent use, it can also be modified to other water outputs to expand its scope of use. Among them, pressing inward rotates the handle body 801 away from the user, and conversely, pressing outward rotates the handle body 801 toward the user.

[0050] In this embodiment, Figure 4-Figure 6 As shown, the valve seat 101 is further provided with a cold water channel 1012, a hot water channel 1011, a water outlet channel 1013, and a flow passage 1014. The water outlet channel 1013 is provided with a first mounting cavity 1015 for mounting the flow sensor 50. The valve seat 101 also has an assembly surface 1017 for mounting the first water outlet device 20 and a second mounting cavity 1016 for mounting the on-off valve 40. The flow passage 1014 connects the second mounting cavity 1016 with the cold water channel 1012. In other embodiments, the sensing end of the flow sensor 50 may also be mounted in the flow passage 1014.

[0051] In this embodiment, Figure 9 、 Figure 12 as well as Figure 13The illustrated handle 70 includes a handle body 801 and a valve core seat 802. One end of the valve core seat 802 is provided with a first mounting position 8021 for connection to a switching element. The other end of the valve core seat 802 is provided with a second mounting position 8022 rotatably connected to the handle body 801. The axes of the first mounting position 8021 and the second mounting position 8022 respectively form the first rotation axis 701 and the second rotation axis 702. The first quantitative switch 601 is located on one side of the second rotation axis 702, and the second quantitative switch 602 is located on the other side of the second rotation axis 702. The first mounting position 8021 is a recessed groove, and the second mounting position 8022 is a cylindrical protrusion. When the handle body 801 rotates about the first rotation axis 701, it rotates the valve core seat 802 and the switching element. When the handle body 801 rotates about the second rotation axis 702, the handle body 801 rotates relative to the valve core seat 802, thereby triggering the first quantitative switch 601 and the second quantitative switch 602, respectively. Furthermore, the handle 70 is further provided with a first actuating portion 9031 and a second actuating portion 9032 for triggering the first quantitative switch 601 and the second quantitative switch 602 respectively.

[0052] In this embodiment, a return spring is provided between the handle body 801 and the valve core seat 802, for returning the handle body 801 to the opposite direction of its pressing and rotating direction. Figure 12 、 Figure 13 As shown, the return spring includes a first return spring 2301 and a second return spring 2302, which are respectively movably mounted outside the first actuating portion 9031 and the second actuating portion 9032. When the handle body 801 is pressed inward, causing the first actuating portion 9031 to trigger the first quantitative switch 601, the external pressing force disappears, and the handle body 801 is reset under the elastic force of the first return spring 2301. Similarly, when the handle body 801 is pressed outward, causing the second actuating portion 9032 to trigger the second quantitative switch 602, the external pressing force disappears, and the handle body 801 is reset under the elastic force of the second return spring 2302.

[0053] This embodiment also provides a water tap, such as Figure 7-13 As shown, the valve body 100 includes a valve body 100 in which the quantitative water outlet device 10 as described above is installed, and further includes a water inlet pipe connected to the water inlet channel and a water outlet pipe 120 connected to the water outlet channel 1013.

A temperature sensing element is also included, and the sensing end of the temperature sensing element is provided in the water outlet channel 1013 or at any position from the water outlet channel 1013 along the water outlet direction to the water outlet end of the water outlet pipe 120, for monitoring the current outlet water temperature. Specifically, the temperature sensing element is provided in the switching device 1402.

[0055] In this embodiment, Figure 11 As shown, the valve body 100 further includes a pressing cap 150, whose threads are adapted to fit on the side of the valve body 100, thereby pressing the manual dosing device against the valve seat 101. The valve body 100 further includes a decorative ring 160, which is connected to the side of the valve body 100. The circuit board 30 is mounted on the decorative ring 160, and a clearance space 170 is provided between the decorative ring 160 and the handle 70 for the handle 70 to rotate and swing.

[0056] In this embodiment, Figure 11 As shown, the valve body 100 is provided with a window 180, within which is a display screen 190. This display screen 190 is electrically connected to the circuit board 30 and is used to display the water temperature value monitored by the temperature sensor and the flow value monitored by the flow sensor 50, thereby visualizing the flow and temperature and improving the user experience. Specifically, when the handle 70 is turned to activate the first water outlet device 20, the display screen 190 displays the current water temperature.
