[0044] like Figure 1 and Figure 2As shown, this embodiment provides a water outlet switching device, which is used on a toilet to switch the brush ring water outlet or the main flush water outlet of the toilet. Specifically, the water outlet switching device includes a body 100 and a switching mechanism 200. The body 100 is provided with a water inlet channel 110, a first water outlet channel 120, a second water outlet channel 130 and a first switching chamber 100a, and the first water outlet channel 120 and the second water outlet channel 130 can be connected to the water inlet channel 110 respectively. The switching mechanism 200 includes a first float 210 and a switching unit 220, the first float 210 is provided in the first switching chamber 100a, and when the first switching chamber 100a is filled with water, the first float 210 can float up and block the entrance of the first water outlet channel 120; the switching unit 220 can open the entrance of the second water outlet channel 130 under the action of an external force, and the switching unit 220 can be reset and block the entrance of the second water outlet channel 130 when the external force is removed. It also includes a first limiting unit 300, which can be in a limiting state when water is flowing into the water inlet channel 110, and limit the first buoy 210 from floating up or falling down; and it can be reset to a non-limiting state when water is not flowing through the water inlet channel 110, so that the first buoy 210 can float up under the action of buoyancy or fall back under the action of gravity. The water outlet switching device of this embodiment can switch the water from the water inlet channel 110 to flow into the first water outlet channel 120 or the second water outlet channel 130 by intermittently flowing water through the water inlet channel 110. The specific switching process is as follows:

[0045] like Figure 2 and Figure 3 As shown, Figure 2 To switch the water outlet device to a state where no water is flowing in, Figure 3 The state where the water outlet device is switched to discharge water from the first water outlet channel 120. Figure 2 In the state, when water enters its water inlet channel 110, the water flow from the water inlet channel 110 can drive the first limiting unit 300 to switch to the limiting state, and jam the first buoy 210 so that the first buoy 210 cannot float up. At this time, the entrance of the first water outlet channel 120 is open, and the water from the water inlet channel 110 can flow into the first water outlet channel 120 and be discharged. It should be emphasized that at this time, since the first water outlet channel 120 is flowing with water, the water in the first switching chamber 100a is in a state of pressure relief, and its pressure cannot flush the switching unit 220, so the entrance of the second water outlet channel 130 is not opened, and the water from the water inlet channel 110 cannot be discharged from the second water outlet channel 130.

[0046] like Figure 3 and Figure 4 As shown, Figure 4 The water outlet device is switched to discharge water from the second water outlet channel 130. Figure 3In the state, when the water flow through the water inlet channel 110 stops, the limiting unit 300 can be reset to the non-limiting state. At this time, the first float 210 floats up under the action of buoyancy and blocks the entrance of the first water outlet channel 120. Next, when the first float 210 has not fallen back, if water is passed through the water inlet channel 110 again, the water flow from the water inlet channel 110 can drive the first limiting unit 300 to switch to the limiting state again, and clamp the first float 210 so that the first float 210 cannot fall, and continue to block the entrance of the first water outlet channel 120. At this time, the water from the water inlet channel 110 has sufficient water pressure to drive the switching unit 220 to open, and allow the water from the water inlet channel 110 to flow into the second water outlet channel 130 and be discharged. Of course, it should be noted that the water outlet device is switched on. Figure 4 If the water inlet channel 110 stops flowing again, the water outlet device is switched back to Figure 2 state, so as to prepare for the next water outlet channel 120 to discharge water.

[0047] In addition, if Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the first limiting unit 300 includes a first one-way valve body 310 and a first elastic member 320, and the first one-way valve body 310 is provided with a movable shaft, and the first elastic member 320 is sleeved on the movable shaft. When water flows through the water inlet channel 110, the water from the water inlet channel 110 can drive the first one-way valve body 310 to move forward and compress the first elastic member 320, and the first one-way valve body 310 moving forward can clamp the first buoy 210 through the movable shaft, so that the first buoy 210 cannot float up or fall back. It should be noted that, in this embodiment, the first one-way valve body 310 and the first elastic member 320 are respectively the valve body and the elastic member of the one-way valve in the prior art, and the first elastic member 320 can also be a spring or other elastic member in the prior art, which will not be repeated here.

[0048] In addition, if Figure 1 and Figure 2 As shown, in this embodiment, the circumference of the first buoy 210 is provided with a limiting portion 211, and the first one-way valve body 310 can clamp the limiting portion 211 and limit the first buoy 210 from floating up or falling back. Specifically, in this embodiment, the limiting portion 211 is a protrusion provided on the circumference of the first buoy 210. Of course, in other embodiments, the limiting portion 211 can also be a groove provided on the circumference of the first buoy 210, which will not be repeated here.

[0049] In addition, if Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the switching unit 220 includes a second one-way valve body 221 and a second elastic member 222. Specifically, when the first water outlet channel 120 is blocked by the first buoy 210, the water from the water inlet channel 110 has sufficient water pressure to drive the second one-way valve body 221 to move forward and compress the second elastic member 222, and the second one-way valve body 221 moving forward can open the entrance of the second water outlet channel 130. Among them, the second one-way valve body 221 and the second elastic member 222 are respectively the valve body and the elastic member of the one-way valve in the prior art, and the second elastic member 222 can also be a spring or other elastic member in the prior art, which will not be repeated here.

[0050] like Figures 1 to 4 As shown, in this embodiment, the water outlet switching device further includes a one-way plug 400, and a drainage hole 100c connected to the water inlet channel 110 is provided at the bottom of the first switching chamber 100a, and the end face of the one-way plug 400 matches the drainage hole 100c. During operation, water inflow into the water inlet channel 110 can drive the one-way plug 400 to move upward and block the drainage hole 100c, so that the water in the first switching chamber 100a will not be discharged from the drainage hole 100c. When the water inlet channel 110 does not flow in, the water in the first switching chamber 100a can be gradually discharged from the drainage hole 100c, so that the first float 210 will gradually fall to the lowest position.

[0051] In addition, in this embodiment, the first water outlet channel 120 is used to provide water for the brush ring, and the second water outlet channel 130 is used to provide main flushing water. By switching the water outlet device, water can be discharged from the first water outlet channel 120 or the second water outlet channel 130.

[0052] This embodiment also provides another water outlet switching device, which is as follows:

[0053] like Figure 5 , Figure 6 and Figure 7As shown, in this embodiment, the body 100 is provided with a second switching chamber 100b connected to the water inlet channel 110 in addition to the first switching chamber 100a, and the first water outlet channel 120 and the second water outlet channel 130 are respectively connected to the first switching chamber 100a and the second switching chamber 100b. The switching unit 220 includes a second float 225, which can float up to open the entrance of the second water outlet channel 130 and fall back to block the entrance of the second water outlet channel 130. It also includes a second limiting unit, which can be in a limiting state when the water inlet channel 110 is filled with water, limiting the second float 225 from floating up or falling; and it can be reset to a non-limiting state when the water inlet channel 110 is not filled with water, allowing the second float 225 to float up under the action of buoyancy or fall back under the action of gravity. The second limiting unit includes a third one-way valve body 223 and a third elastic member 224. When water flows through the water inlet channel 110, the water from the water inlet channel 110 can drive the third one-way valve body 223 to move forward and compress the third elastic member 224, and the third one-way valve body 223 moving forward can clamp the second float 225, so that the second float 225 cannot float up or fall back. Among them, the third one-way valve body 223 and the third elastic member 224 are respectively the valve body and elastic member of the one-way valve in the prior art, and the third elastic member 224 can also be a spring or other elastic member in the prior art, which will not be repeated here. In addition, the limiting unit 300 is consistent with the above embodiment and will not be repeated here.

[0054] The specific switching process of this water outlet device is as follows:

[0055] like Figure 5 and Figure 6 As shown, Figure 5 To switch the water outlet device to a state where no water is flowing in, Figure 6 The state where the water outlet device is switched to discharge water from the first water outlet channel 120. Figure 5 In the state, when water enters its water inlet channel 110, the water flow from the water inlet channel 110 can drive the first limiting unit 300 to switch to the limiting state, and clamp the first buoy 210 so that the first buoy 210 cannot float up. At this time, the entrance of the first water outlet channel 120 is open, and the water from the water inlet channel 110 can flow into the first water outlet channel 120 and be discharged. At this time, the third one-way valve body 223 moves forward under the action of water pressure and clamps the second buoy 225, so that the second buoy 225 cannot float up, and continues to block the entrance of the second water outlet channel 130. Therefore, the entrance of the second water outlet channel 130 is not opened, and the water from the water inlet channel 110 cannot be discharged from the second water outlet channel 130.

[0056] like Figure 6 and Figure 7 As shown, Figure 7The water outlet device is switched to discharge water from the second water outlet channel 130. Figure 6 In the state, when the water inlet channel 110 stops passing water, the first limiting unit 300 can be reset to the non-limiting state, at which time the first buoy 210 floats up under the action of buoyancy and blocks the entrance of the first water outlet channel 120. The third one-way valve body 223 is also reset under the action of the third elastic member 224, and the second buoy 225 floats up under the action of buoyancy and opens the entrance of the second water outlet channel 130. Then, if water is passed through the water inlet channel 110 again, the water flow from the water inlet channel 110 can drive the first limiting unit 300 to switch to the limiting state again, and clamp the first buoy 210 so that the first buoy 210 cannot fall, and continue to block the entrance of the first water outlet channel 120. At the same time, the third one-way valve body 223 also moves forward again and clamps the second buoy 225 so that the second buoy 225 cannot fall, so that the entrance of the second water outlet channel 130 is in an open state. At this time, the water from the water inlet channel 110 can only flow into the second water outlet channel 130 and be discharged. Figure 7 If the water inlet channel 110 stops flowing again, the water outlet device will return to the state of Figure 5 state, so as to prepare for the next water outlet channel 120 to discharge water.

[0057] This embodiment provides another water outlet switching device, which is as follows:

[0058] like Figure 8 , Fig. 9 and Fig.10 As shown, in this embodiment, the switching unit 220 includes a swing piece 226 hinged to the body 100, and the swing piece 226 can swing relative to the body 100. Specifically, the floating first buoy 210 can drive the swing piece 226 to swing and open the entrance of the second water outlet channel 130, and the swing piece 226 can be reset and block the entrance of the second water outlet channel 130 when the external force is removed. Among them, the swing piece 226 is S-shaped, and the swing piece 226 is provided with a matching surface 226a, and the matching surface 226a matches the entrance of the second water outlet channel 130, and the swing piece 226 can drive the matching surface 226a to block the entrance of the second water outlet channel 130.

[0059] The specific switching process of this water outlet device is as follows:

[0060] like Figure 8 and Fig. 9 As shown, Figure 8 To switch the water outlet device to a state where no water is flowing in, Fig. 9 The state where the water outlet device is switched to discharge water from the first water outlet channel 120. Figure 8In the state, when water enters the water inlet channel 110, the water flow from the water inlet channel 110 can drive the first limiting unit 300 to switch to the limiting state, and clamp the first buoy 210 so that the first buoy 210 cannot float up. At this time, the entrance of the first water outlet channel 120 is open, and the water from the water inlet channel 110 can flow into the first water outlet channel 120 and be discharged. At this time, the swing piece 226, under the action of water pressure, just blocks the entrance of the second water outlet channel 130, so the entrance of the second water outlet channel 130 is not opened, and the water from the water inlet channel 110 cannot be discharged from the second water outlet channel 130.

[0061] like Fig. 9 and Fig.10 As shown, Fig.10 The water outlet device is switched to discharge water from the second water outlet channel 130. Fig. 9 In the state, when the water inlet channel 110 stops passing water, the first limiting unit 300 can be reset to the non-limiting state, and the first buoy 210 floats up under the action of buoyancy and blocks the entrance of the first water outlet channel 120. At the same time, the floating first buoy 210 will press against the swing piece 226, causing the swing piece 226 to hinge and open the entrance of the second water outlet channel 130. Then, if water is passed through the water inlet channel 110 again, the water flow from the water inlet channel 110 can drive the first limiting unit 300 to switch to the limiting state again, and clamp the first buoy 210 so that the first buoy 210 cannot fall, and continue to block the entrance of the first water outlet channel 120. At the same time, the buoy that remains in the floating state can continue to press against the swing piece 226 so that the swing piece 226 continues to be in the state of opening the entrance of the second water outlet channel 130. At this time, the water from the water inlet channel 110 can only flow into the second water outlet channel 130 and be discharged. Of course, it should be noted that the water outlet device is switched Fig.10 If the water inlet channel 110 stops flowing again, the water outlet device will return to the state of Figure 8 state, so as to prepare for the next water outlet channel 120 to discharge water.

[0062] The present embodiment also provides a toilet (not shown), which includes a toilet seat (not shown), a cover mechanism (not shown) and a water switching device. The toilet seat is provided with a brush ring water inlet (not shown) and a main flush water inlet (not shown). The water switching device is the water switching device provided by the present embodiment above. The water switching device can intermittently pass water through the water inlet channel 110 to switch the water from the water inlet channel 110 to flow into the brush ring water inlet or the main flush water inlet for water supply, thereby realizing the switching of toilet brush ring water outlet or main flush water outlet.

[0063] The water outlet switching device provided in the present embodiment can switch the water outlet of the first water outlet channel 120 or the second water outlet channel 130 by intermittent water flow, thereby realizing the switching of the water outlet of the toilet brush ring or the main flushing water outlet. This water outlet switching device does not have a motor or a solenoid valve, etc., but uses a mechanical structure to realize the water outlet switching of the first water outlet channel 120 or the second water outlet channel 130 through the pressure and buoyancy of the incoming water. Compared with the existing switching using a motor or a solenoid valve, this water outlet switching device not only has the characteristics of low cost, but also has better waterproof reliability because it does not need to power the water outlet switching device.
