DETAILED DESCRIPTION

[0028] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The utility model relates to a water outlet device, comprising a main body 100 and a first water diversion valve 300 .

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, the main body 100 can be a waterway plate structure, and the main body 100 can be installed in the housing 400 of the water outlet device. The interior of the main body 100 includes a water inlet channel group, a first functional channel 120, and a second functional channel 130. The first functional channel 120 is used to connect to an external spray gun 200 for use. The spray gun 200 has an independent switch for opening and closing. The spray gun 200 can be connected to one end of the first functional channel 120 via a hose. The second functional channel 130 is connected to the first functional channel 120. The first water diverter valve 300 is installed on the main body 100 and is located at the connection point between the first functional channel 120 and the second channel. The water inlet channel group is connected to the first water diverter valve 300, and the water inlet channel group is connected to an external water supply system such as a water heater, a tap water pipe, etc. A valve can be installed on the water inlet channel group to control whether water is flowing, and the valve can be used to control whether the water inlet channel group supplies water to the first water diverter valve 300. The first water diverter valve 300 controls the water supply to the first and second functional channels 120 and 130. The first water diverter valve 300 is equipped with an elastic valve core 310, which elastically moves within the valve. The elastic valve core 310 can move between a first position and a second position based on changes in water pressure within the first functional channel 120. Initially, there is no water in the first functional channel 120. Due to its own elastic force, the elastic valve core 310 is in the first position, sealing the water inlet side of the second functional channel 130. This maintains communication between the first functional channel 120 and the water inlet channel assembly. When the water inlet channel assembly selects to supply water to the first water diverter valve 300, water flows through the first water diverter valve 300 and, under the action of the elastic valve core 310, flows into the first functional channel 120. If the user then opens the spray gun 200, water flows through the first functional channel 120 and is sprayed out of the spray gun 200 for use. If the user does not open the spray gun 200, the spray gun 200 is in a closed state, and water flows into the first function channel 120 and gradually fills the first function channel 120 with water. Figure 4As shown, when the first functional channel 120 is filled with water, it is at full pressure. At this point, the water pressure pushes the elastic valve core 310 to move, opening the second functional channel 130. Water flows through the first water diverter valve 300 and enters the second functional channel 130, where it is discharged from the second functional channel 130. The second functional channel 130 can be a direct discharge system, where water is discharged directly from the second functional channel 130. For example, the outlet of the second functional channel 130 can be located at the bottom of the main body 100, facing downward. The second functional channel 130 is used to implement the downward discharge function of the water outlet device. The outlet of the second functional channel 130 can also be connected to a bubbler, etc., to achieve other water discharge effects. If the spray gun 200 is turned on, the water stored in the first functional channel 120 is immediately sprayed out of the spray gun 200, and the first functional channel 120 is no longer under full pressure. The elastic valve core 310 elastically returns to its original position, sealing the water inlet side of the second functional channel 130. After use, the water inlet channel group is controlled to stop supplying water to the first water diverter valve 300. The first water diverter valve 300 automatically switches between the first functional channel 120 and the second functional channel 130, eliminating the need for manual operation of the first water diverter valve 300. This improves operational convenience and optimizes the internal waterway structure of the main body 100. Furthermore, the presence of water flowing from the second functional channel 120 indicates whether the water inlet channel group has shut off the water supply to the first water diverter valve 300, preventing the first functional channel 120 from being exposed to pressure from the external water supply system for an extended period.

[0031] In some embodiments of the present invention, Figure 3 、 Figure 4 and Figure 7As shown, the first water diverter valve 300 includes a first valve chamber 330. The first valve chamber 330 is provided with a first water inlet valve port 331, a first water outlet valve port 332, and a second water outlet valve port 333. The first valve chamber 330 can be cylindrical. Alternatively, the first water inlet valve port 331 may be located on the sidewall of the first valve chamber 330, the first water outlet valve port 332 may be located at the bottom of the first valve chamber 330, and the second water outlet valve port 333 may be located at the top of the first valve chamber 330. The first water inlet valve port 331 connects the first valve chamber 330 with the water inlet channel assembly. The first water outlet valve port 332 connects with the first functional channel 120, and the second water outlet valve port 333 connects with the second functional channel 130. An elastic valve core 310 is installed in the first valve chamber 330 and moves axially up and down. When the elastic valve core 310 moves downward, it is in the first position, and when it moves upward, it is in the second position. The elastic valve core 310 exerts an elastic force that causes it to move from the second position toward the first position. When the elastic valve core 310 moves down to the first position, the upper part of the elastic valve core 310 blocks the second water outlet valve port 333. When the elastic valve core 310 moves up to the second position, the upper part of the elastic valve core 310 opens the second water outlet valve port 333. The first water outlet valve port 332 remains in communication with the first functional channel 120. The lower end of the elastic valve core 310 can be extended into the first functional channel 120. When the first functional channel 120 is filled with water, the water pressure will act on the bottom of the elastic valve core 310. The water pressure overcomes the elastic force of the elastic valve core 310 and pushes the elastic valve core 310 upward to the second position. The elastic valve core 310 includes a valve stem 311 and an elastic member 312. The elastic member 312 applies an elastic force to the valve stem 311 that causes the valve stem 311 to move toward the first position. The elastic member 312 can be a spring that is sleeved on the valve stem 311. One end of the spring is connected to the valve stem 311, and the other end is connected to the valve body of the first water diverter valve 300. The spring applies an elastic force to the valve stem 311, and the direction of the elastic force is from the second position to the first position.

[0032] Further, such as Figure 3 、 Figure 4 and Figure 7As shown, a conical and elastic water retaining member 320 is sleeved on the elastic valve core 310. The water retaining member 320 can be made of an elastic material such as rubber. The water retaining member 320 is located in the first functional channel 120, the upper end of the water retaining member 320 is the small end, and the lower end is the large end, and the outer diameter of the large end is larger than the outer diameter of the small end. The small end of the water retaining member 320 is closer to the second water outlet valve port 333 than its large end, that is, in the first functional channel 120, the small end of the water retaining member 320 is located on the upstream side of the large end. The outer wall of the large end of the water retaining member 320 can be elastically deformed in the radial direction. The outer wall of the large end of the water retaining member 320 can abut against the inner wall of the first functional channel 120. Under normal circumstances, the outer wall of the large end of the water retaining member 320 expands radially outward and abuts against the inner wall of the first functional channel 120. There is a certain gap between the outer wall of the small end of the water retaining member 320 and the inner wall of the first functional channel 120. When water flows toward the first functional channel 120, the water flows from the small end toward the large end along the outer wall of the water retaining member 320. The water impacts the large end outer wall of the water retaining member 320, causing the large end of the water retaining member 320 to shrink radially inward and away from the inner wall of the first functional channel 120, and the water continues to flow downstream of the first functional channel 120. When the first functional channel 120 is filled with water and cannot be drained out through the spray gun 200, no water flow impacts the large end outer wall of the water retaining member 320, and the large end of the water retaining member 320 is radially reset to abut against the inner wall of the first functional channel 120. The water pressure in the first functional channel 120 acts on the large end plane of the water retaining member 320, pushing the water retaining member 320 axially upward, driving the elastic valve member to switch upward from the first position to the second position.

[0033] In some specific embodiments of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 8As shown, the water inlet channel group includes a cold water channel 111, a hot water channel 112, a mixing water channel 113, a mixing valve 140, and a second water diverter valve 150. The water inlet end of the cold water channel 111 is connected to the cold water pipe of the external water supply system. The water inlet end of the hot water channel 112 is connected to the hot water pipe of the external water supply system. A one-way valve can be installed in each of the cold water channel 111 and the hot water channel 112 to control the unidirectional flow of external water into the cold water channel 111 and the hot water channel 112. The cold water channel 111 and the hot water channel 112 are connected in parallel to the water inlet side of the mixing valve 140. The mixing valve 140 is used to adjust the mixing ratio of cold and hot water in the cold water channel 111 and the hot water channel 112. The mixing valve 140 is installed on the upstream side of the mixing water channel 113, and the mixed water enters the mixing water channel 113. The second water diverter valve 150 is installed on the downstream side of the mixing water channel 113 and is provided with a first flow channel 151. The first flow channel 151 is used to control the opening and closing of the mixing channel 113 and the first water diverter valve 300. The second water diverter valve 150 is rotatably mounted on the main body 100. By rotating the second water diverter valve 150, the first flow channel 151 and the first water diverter valve 300 can be connected or disconnected. When the first flow channel 151 and the first water diverter valve 300 are connected, water in the mixing channel 113 can enter the first water diverter valve 300 through the first flow channel 151. When the first flow channel 151 and the first water diverter valve 300 are disconnected, water in the mixing channel 113 cannot enter the first water diverter valve 300 through the first flow channel 151.

[0034] Furthermore, the main body 100 also includes a third functional channel 160. The third functional channel 160 is used to connect to the top spray outlet. The water outlet end of the third functional channel 160 can be set upward at the top of the main body 100. The third functional channel 160 is located on the water outlet side of the second water diverter valve 150, and the second water diverter valve 150 is provided with a second flow channel 152. The second flow channel 152 is used to control the opening and closing of the mixing water channel 113 and the third functional channel 160. When the second water diverter valve 150 is rotated, when the second flow channel 152 and the third functional channel 160 are aligned and connected, the water in the mixing water channel 113 can enter the third functional channel 160 through the second flow channel 152. When the second flow channel 152 and the third functional channel 160 are misaligned and disconnected, the water in the mixing water channel 113 cannot enter the third functional channel 160 through the second flow channel 152.

[0035] Furthermore, the main body 100 also includes a fourth functional channel 170. The fourth functional channel 170 is used to connect a handheld shower. The fourth functional channel 170 is located on the water outlet side of the second water diverter valve 150. The second water diverter valve 150 is provided with a third flow channel 153. The third flow channel 153 is used to control the opening and closing of the mixing water channel 113 and the fourth functional channel 170. When the second water diverter valve 150 is rotated, when the third flow channel 153 and the fourth functional channel 170 are aligned and connected, the water in the mixing water channel 113 can enter the fourth functional channel 170 through the third flow channel 153. When the third flow channel 153 and the fourth functional channel 170 are misaligned and disconnected, the water in the mixing water channel 113 cannot enter the fourth functional channel 170 through the third flow channel 153.
