DETAILED DESCRIPTION

[0039] Combine the following Figure 1-13 The present invention is described in detail.

[0040] This embodiment provides a water outlet device 10, which is provided with a water inlet channel, a water outlet channel 1013 and a flow passage 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] The 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 by signal, wherein the switch valve 40 is used to open or close the flow passage 1014 to control whether the water outlet passage 1013 is connected to the water inlet passage, and the sensing end of the flow sensor 50 is arranged in the water outlet passage 1013 or the flow passage 1014 to count 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. The handle 70 is provided with a first rotation axis 701 and a second rotation axis 702 which are 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 for opening and closing the first water outlet device 20, and when the handle 70 rotates around the second rotation axis 702, it also constitutes a second switch that triggers 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. When in use, by changing the movement posture of the handle 70, it can respectively constitute a first switch for driving the first water outlet device 20 and a second switch for driving the second water outlet device, avoiding the need to set two handles 70 to drive the first water outlet device 20 and the second water outlet device respectively, realizing manual and automatic quantitative water outlet, thereby reducing the product volume and improving the user experience.

[0046] In this embodiment, Fig.12 , Fig.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 handle 70 is swung to trigger 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 both the cold water chamber and the hot water chamber are not 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 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 a 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 it drives the switching member to rotate, so that the switching member switches between the first state, the second state and the third state, thereby realizing the manual water discharge function. Fig. 9As shown, when the handle 70 is in position A, the switching member is in the first state; the handle 70 is driven to rotate around the first rotation axis 701, so that it moves from position A to position B, and the switching member is driven to rotate to the second state; the handle 70 is driven to rotate until it cannot rotate, so that it moves from position B to position C, and the switching member is driven to rotate to the third state. Among them, the rotation angle of the handle 70 is the angle α corresponding to the position from position A to position C, and position B is any position between position A and position 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. Fig.12 As shown, the handle body 801 is pressed inward to rotate it by B1 degrees, the handle 70 triggers the first quantitative switch 601, the circuit board 30 controls the switch valve 40 to open the flow channel 1014, cold water flows out, and 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. Fig.13 As shown, the handle body 801 is pressed outward to rotate it B2 degrees, and the handle 70 triggers the second quantitative switch 602. The water output process is the same and will not be repeated. The first water output program and the second water output range 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. In the subsequent use process, it can also be modified to other water outputs to expand its scope of use. Among them, pressing inward means that the handle body 801 rotates away from the user, and conversely, pressing outward means that the handle body 801 rotates in a direction close to the user.

[0050] In this embodiment, Figure 4-Figure 6 As shown, the valve seat 101 is also included.

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. Among them, the first mounting position 8021 is a groove, and the second mounting position 8022 is a cylindrical convex portion. When the handle body 801 rotates around the first rotation axis 701, it drives the valve core seat 802 to rotate together and drives the switching member to rotate; when the handle body 801 rotates around 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 also 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.
