[0035] Example 1

[0036] The following is combined with Figures 1-11 This utility model will be described in detail.

[0037] This embodiment provides a water outlet device with a water outlet path, including a first switching device 20 disposed in the water outlet path. The first switching device 20 includes a first valve body 201 and a first switching element 202 movably disposed in the first valve body 201. The first valve body 201 is provided with a first inlet 101 and a first outlet 102 and a second outlet 103 connected to the first inlet 101. The first switching element 202 has a first position and a second position during the movement process.

[0038] When the first switching component 202 is in the first position, the first inlet 101 is connected to the first outlet 102, resulting in a single water path outlet. When the first switching component 202 is in the second position, the first inlet 101 is connected to the first outlet 102 and the second outlet 103, resulting in a dual water path outlet, increased water flow area, and increased water flow rate. The first switching component 202 is always completely submerged in water during movement, and the water pressure areas on the upper and lower surfaces of the first switching component 202 are equal. The water pressure area on the upper surface refers to the sum of the areas of all upward-facing surfaces, and the water pressure area on the lower surface refers to the sum of the areas of all downward-facing surfaces, ensuring that the first switching component 202 is in a state of force balance. Figure 10As shown. Therefore, the force driving the first switching element 202 will not change with the water flow rate, thereby improving the user experience. In practical applications, the difference between the water pressure-receiving areas of the upper and lower surfaces of the first switching element 202 does not exceed 10%, that is, the water pressure-receiving area of ​​the upper surface is 10% more or less than that of the lower surface. Within this range, the first switching element 202 is basically in a state of force balance, and has almost no impact on the user's use.

[0039] like Figure 4 As shown, the first switching element 202 divides the first valve body 201 into a first space 301 and a second space 302. When the first switching element 202 is in the second position, the first water inlet 101 connects to the first space 301 and the second space 302. Specifically, the first valve body 201 is provided with a first water inlet 101 and a first water outlet 102 at the position between the first space 301 and the second space 302. The first switching element 202 is provided with a first connecting channel 401. One end of the first switching element 202 is connected to a first shaft 203. A second connecting channel 402 is provided between the first switching element 202 and the first shaft 203. The second space 302 is connected to the first water inlet 101 through the first connecting channel 401 and the second connecting channel 402, so that water can fill the first space 301 and the second space 302, and the first switching element 202 is completely submerged in water.

[0040] The second water outlet 103 is connected to the first space 301. When the first switching element 202 is in the first position, the first water inlet 101 is connected to the first space 301 through the first water outlet 102 and the second water outlet 103. The first switching device 20 also includes an elastic element 204. The first end of the elastic element 204 abuts against the first valve body 201, and the second end of the elastic element 204 abuts against the first shaft 203 through the first connecting flow channel 401 and the second connecting flow channel 402. The elastic element 204 is used to provide a force to reset the first switching element 202 from the second position to the first position. Therefore, by default, the first switching element 202 is in the first position, that is, single water outlet, to avoid excessive water flow causing splashing. The first switching element 202 and the first shaft 203 can be integrally formed or separately formed.

[0041] The first valve body 201 includes a first main body 2011 and a first water distribution body 2012 connected to each other. A first switching element 202 is movably and sealingly connected to the first main body 2011. The space enclosed by the first switching element 202 and the first main body 2011 constitutes a second space 302. A first shaft 203 is movably and sealingly connected to the first water distribution body 2012. The internal space of the first water distribution body 2012 constitutes the first space 301. When the first switching element 202 is in the first position, the first switching element 202 is sealed and connected to the first water distribution body 2012. The gap between the first water distribution body 2012 and the first main body 2011 constitutes a first water inlet 101. The first water distribution body 2012 is provided with a first water outlet 102 and a second water outlet 103.

[0042] like Figure 11 As shown, the first body 2011 is also provided with a protrusion 2013 facing the first switching member 202 to prevent it from completely abutting against the first body 2011 when the first switching member 202 is pressed to switch to the second position. Specifically, when the first switching member 202 is in the second position, the first switching member 202 abuts against the protrusion 2013 and forms a gap between it and the first body 2011. When water flows through the first connecting channel 401 into the second space 302, the gap between the first body 2011 and the first switching member 202 is filled with water, thereby exerting a force on the first switching member 202, so that the first switching member 202 is in a state of water pressure balance.

[0043] The first switching device 20 also includes a first control element 205. One end of the first shaft 203 passes through the first water distribution body 2012 and is engaged with the first control element 205. By operating the first control element 205, the first switching element 202 can be controlled to move between the first position and the second position.

[0044] like Figures 6 to 9 As shown, the outlet end of the first switching device 20 is connected to the second switching device 50. The second switching device 50 includes a second valve body 501 and a second switching element 503 movably disposed on the second valve body 501. The second valve body 501 is provided with a second inlet 601 and a first flow passage 602 and a second flow passage 603 connected to the second inlet 601. The second inlet 601 is connected to the first flow passage 102 and the second flow passage 103. By moving the second switching element 503, the second inlet 601 is connected to the first flow passage 602 or the second flow passage 603. The first flow passage 602 and the second flow passage 603 are connected to waterways with different water outlet patterns to meet the diverse usage needs of users.

[0045] The second valve body 501 includes a second main body 5011 and a second water distribution body 5012 connected to each other. The gap between the second switching member 503 and the second main body 5011 forms a second flow passage 603. The gap between the second switching member 503, the second main body 5011, and the second water distribution body 5012 forms a second inlet 601 and a first flow passage 602. A second control member 502 is also rotatably connected to the outside of the second valve body 501. One end of the second switching member 503 passes through the second water distribution body 5012 and engages with the first end of the second control member 502. By controlling the movement of the second end of the second control member 502, the first end of the second control member 502 drives the second switching member 503 to move accordingly, realizing the switching of the second inlet 601 with the first flow passage 602 or the second flow passage 603. After switching, under the pressure of the water flow in the first flow passage 602 or the second flow passage 603, the second switching member 503 can be maintained in the adjusted position without external force.

[0046] like Figures 6 to 9 As shown, the water outlet of the second switching device 50 is provided with a face mask water outlet device 70. The face mask water outlet device 70 is provided with an aerated water path and a shower water path. The first flow channel 602 is connected to the aerated water path, and the second flow channel 603 is connected to the shower water path. Specifically, the face mask water outlet device 70 includes a face mask body 702 and an aerator 701 installed on the face mask body 702. The face mask body 702 is provided with a plurality of water outlet holes, which constitute the shower water path, and the internal channels of the aerator 701 constitute the aerated water path.

[0047] like Figure 4 , Figure 9 As shown, the inlet end of the first switching device 20 is connected to a connector device 80. The connector device 80 includes a connector body 801 and a one-way valve 802 provided in the connector body 801. The one-way valve 802 opens in one direction along the water outlet direction. The connector body 801 makes it easy for the water outlet device to be connected to the pipe 120. The one-way valve 802 prevents water from flowing back.

[0048] In this embodiment, a housing 90 is also included. The housing 90 is provided with a connector device 80, a first switching device 20, a second switching device 50 and a faceplate water outlet device 70 that are connected in sequence along the water outlet direction. The side wall of the housing 90 is also provided with an active window 901 for operating the first switching component 202 and the second switching component 503. The first control component 205 and the second control component 502 are located at the corresponding active window 901.

[0049] The working process of the water outlet device proposed in this embodiment is as follows:

[0050] By default, the first switching element 202 is located in the first position under the action of the elastic element 204, which is a single water outlet. Figure 6 and Figure 8 As shown, the first switching element 202 is sealed to the first water distribution body 2012. At this time, the first inlet 101 is connected to the first outlet 102. After the water flows through the one-way valve 802, it enters the first switching device 20 through the first inlet 101. A portion of the water flowing out of the first outlet 102 enters the first space 301 through the second outlet 103. The water in the first space 301 flows into the second space 302 through the second connecting channel 402 and the first connecting channel 401, so that the first switching element 202 is completely submerged in water, achieving hydraulic balance. Another portion of the water flowing out of the first outlet 102 flows to the second inlet 601. By moving the second switching element 503, the second inlet 601 is connected to either the first flow channel 602 or the second flow channel 603, thereby controlling the water outlet pattern. When the second inlet 601 is connected to the first flow channel 602, as... Figure 6 As shown, this is the outlet for aerated water; when the second inlet 601 is connected to the second flow channel 603, as... Figure 8 As shown, the shower head is currently dispensing water.

[0051] When a stronger water flow is needed, press the first switching element 202 to switch it to the second position, causing the first switching element 202 to abut against the protrusion 2013. The first switching element 202 moves from the first position to the second position, at which point there is dual water outlet. Figure 7 and Figure 9 As shown, at this time, the elastic element 204 is compressed, the first switching element 202 is disengaged from the first water distribution body 2012, and the first inlet 101 is connected to the first outlet 102 and the second outlet 103, increasing the water flow area and raising the outflow rate. At this time, the first inlet 101 is connected to the first space 301, and simultaneously, the first inlet 101 is connected to the first connecting channel 401 and the second space 302 through the second connecting channel 402. The gap between the first switching element 202 and the first body 2011 is filled with water, so that the first switching element 202 is completely submerged in water to achieve hydraulic balance. After flowing out from the first outlet 102 and the second outlet 103, the water flows to the second inlet 601. By moving the second switching element 503, the second inlet 601 is connected to either the first flow channel 602 or the second flow channel 603, thereby controlling the water flow pattern. When the second inlet 601 is connected to the first flow channel 602, as... Figure 7 As shown, this is the outlet for aerated water; when the second inlet 601 is connected to the second flow channel 603, as... Figure 9 As shown, the shower head is currently dispensing water.

[0052] When it is necessary to switch to the default water flow rate, stop pressing the first switching element 202. The first switching element 202 will return to the first position under the elastic force of the elastic element 204. The first water inlet 101 and the second water outlet 103 will no longer be connected. The first switching device 20 will switch from dual water outlet to single water outlet.
