It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

Example

[0040] Cooperate Figures 1 to 4 As shown, the utility model discloses a switching structure, which is mainly used in a smart toilet to realize automatic switching of two water channels.

[0041] A switching structure, characterized in that it includes:

[0042] A body 10, wherein the body 10 is provided with a switching chamber 11, a water inlet 121, a first water outlet 122, and a second water outlet 131 communicated with the switching chamber 11;

[0043] A switching member 20, wherein the switching member 20 is movably disposed in the switching chamber 11, and when the switching member 20 moves to a first position, the water inlet 121 is connected to the first water outlet 122, and when the switching member 20 moves to a second position, the water inlet 121 is connected to the second water outlet 131;

[0044] A driving member 30 cooperates with the switching member 20 to drive the switching member 20 to move toward the second position. The driving force of the driving member 30 makes the switching member 20 always have a tendency to move toward the second position.

[0045] The switching chamber 11 is in the first water level state, the self-weight of the switching member 20 overcomes the driving force of the driving member 30 so that the switching member 20 moves to the first position, the water inlet 121 enters water, and the switching member 20 is kept in the first position under the action of the water flow pressure, most of the water flow from the water inlet 121 flows out through the first water outlet 122, and a small part of the water flow enters the switching chamber 11 for storage, so that the switching chamber 11 rises to the second water level state;

[0046] When the switching chamber 11 is at the second water level, the self-weight of the switching member 20 is partially or completely offset by the buoyancy, the water inlet 121 stops water, and the switching member 20 moves to the second position under the driving force of the driving member 30 .

[0047] In this embodiment, the second water level in the second water level state is higher than the first water level in the first water level state; when the switching chamber 11 is in the first water level state, there is no water in the switching chamber 11 or it is in a low water level state; when the switching chamber 11 is in the second water level state, the switching chamber 11 is in a high water level state.

[0048] Cooperate Figure 3 to Figure 4 As shown, the switching chamber 11 is in the first water level state, and the switching member 20 is in the first position. At this time, the switching structure is in the first water outlet state. The water inlet 121 impacts the switching member 20 downward, and the switching member 20 is subjected to the downward pressure of the water flow. At the same time, the switching member 20 is also subjected to the downward gravity and the upward driving force of the driving member 30. In this state, the switching member 20 overcomes the driving force of the driving member 30 under the action of the water flow pressure and its own gravity and remains in the first position in the switching chamber 11 and seals the second water outlet 131. Water flows out of the first outlet and no water flows out of the second outlet. In this process, the water level in the switching chamber 11 rises to the second water level, and correspondingly, the upward buoyancy of the stored water on the switching member 20 becomes larger;

[0049] When the water inlet 121 stops taking in water in the first water outlet state, the water flow pressure disappears, and at the same time, a certain amount of water is stored in the switching chamber 11. At this time, the switching member 20 overcomes its own gravity and moves upward to the second position under the action of the driving force of the driving member 30 and the buoyancy (water stored in the switching chamber 11), and the switching structure switches from the first water outlet state to the second water outlet state. The switching member 20 seals the first water outlet 122 and opens the second water outlet 131. Water flows out of the second water outlet 131 while no water flows out of the first water outlet 122. At the same time, water flows in from the water inlet 121 again, and the water flow from the water inlet 121 directly enters the switching chamber 11, so that the switching chamber 11 maintains the second water outlet state.

[0050] In the second water outlet state, the water inlet 121 stops taking in water, and the switching structure maintains the second water outlet state for a certain period of time. When the water in the switching chamber 11 decreases by flowing out through the second water outlet 131, the water in the switching chamber 11 is emptied or basically emptied, and the buoyancy of the switching member 20 is also reduced. The switching member 20 moves downward. At this time, water is taken in by the water inlet 121 again, and the switching member 20 is subjected to the downward pressure of the water flow, causing the switching structure to switch to the first water outlet state again. Or when the water in the switching chamber 11 is emptied or basically emptied, the switching structure stops working. When working again, water is taken in by the water inlet 121, and the switching structure enters the first water outlet state.

[0051] Among them, when the switching structure switches from the first water outlet state to the second water outlet state, the time for the water inlet 121 to stop taking in water should be less than 1s. If the time is too long, the water stored in the switching chamber 11 will flow out through the second water outlet 131, the buoyancy of the switching component 20 will be too small, the switching component 20 will not be able to rise to the upper limit position, and the switching structure will not be able to switch to the second water outlet state; when the switching structure switches from the second water outlet state to the first water outlet state, the time for the water inlet 121 to stop taking in water should be greater than 0.1s. If the time is too short, there is still a lot of water stored in the switching chamber 11, the buoyancy of the switching component 20 will be too large, the switching component 20 will not be able to descend to the lower limit position, and the switching structure will not be able to switch to the first water outlet state.

[0052] The switching member 20 is provided with a water baffle 21 corresponding to the water inlet 121. When the switching member 20 moves to the first position, most of the water flow directly impacts the water baffle 21, so that the switching member 20 is kept in the first position under the impact force and pressure of the water flow; when the switching member 20 moves to the second position, most of the water flow avoids impacting the water baffle 21, and the switching member 20 is kept in the second position under the driving force of the driving member 30 and / or the water flow pressure. The water baffle 21 is arranged near the water inlet 121. When the switching structure is in the first water outlet state, most of the water flows out through the first water outlet 122, and the remaining small part of the water flow enters the switching chamber 11 for storage, laying the foundation for subsequent switching to the second water outlet state; when the switching structure is in the second water outlet state, as the position of the switching member 20 changes, the water baffle 21 is basically misaligned with the water inlet 121, and the water entering the water inlet 121 directly enters the switching chamber 11, and then flows out through the second water outlet 131.

[0053] In this embodiment, the water inlet 121 and the first water outlet 122 are arranged at the top of the switching chamber 11, the second water outlet 131 is arranged at the bottom of the switching chamber 11, and the switching member 20 is movably arranged up and down in the switching chamber 11. The top of the switching member 20 is provided with a first sealing portion 23 corresponding to the first water outlet 122, and the bottom of the switching member 20 is provided with a second sealing portion 24 corresponding to the second water outlet 131, which can be respectively abutted and sealed with the first water outlet 122 and the second water outlet 131. Specifically, the first sealing portion 23 is provided with a first conical surface. When the switching member 20 moves to the second position, the first conical surface is sealed with the first water outlet 122, and the water flow impacts the second conical surface so that the switching member 20 has a tendency to move to the second position; the second sealing portion 24 is provided with a second conical surface. When the switching member 20 moves to the first position, the second conical surface is sealed with the second water outlet 131, and the water flow impacts the first conical surface so that the switching member 20 has a tendency to move to the first position; the first sealing portion 23 and the second sealing portion 24 both have a truncated cone portion, the side surface of which forms the first conical surface and the second conical surface, and is sealed and engaged with the first water outlet 122 or the second water outlet 131 through the annular inclined surface (the first conical surface and the second conical surface), so that the sealing effect is better. The water retaining plate 21 is horizontally arranged on the top side of the switching member 20.

[0054] The switching member 20 is made of plastic, and its own weight must be increased in order to enable its gravity to meet the requirements during the switching process between the two water outlet states. Preferably, a counterweight material is provided on the switching member 20. Specifically, the switching member 20 is provided with a counterweight cavity 22, and the switching member 20 is provided with a feed port 221 connected to the counterweight cavity 22, and the counterweight cavity 22 is filled with a counterweight. The counterweight can be solid or liquid, and the specific material can also be selected in a variety of ways. In this embodiment, the feed port 221 is provided at the top of the switching member 20, and the counterweight in the switching member 20 is water, which enters and is stored in the counterweight cavity 22 of the switching member 20 through the feed port 221.

[0055] The driving member 30 is a compression spring, one end of which abuts against the bottom end of the switching member 20, and the other end abuts against the bottom wall of the switching chamber 11. Specifically, an annular groove 25 is provided at the bottom end of the switching member 20, and the compression spring is installed in the annular groove 25, and its bottom end abuts against the bottom wall of the switching chamber 11. The compression spring is always in a compressed state, and always provides an upward force acting on the switching member 20. Of course, the compression spring is one of the designs of the driving member 30, and the driving member 30 can also be designed as a magnet (a magnet with the same polarity is respectively provided at the bottom end of the switching member 20 and the corresponding bottom wall of the switching chamber 11), or it includes both a compression spring and a magnet, or other applicable designs.

[0056] The first water outlet 122 is connected to the brush ring water path 123 of the toilet, the second water outlet 131 is connected to the main flushing water path 132 of the toilet, and the water inlet 121 is connected to the water supply mechanism. When the switching structure is in the first water outlet state, the brush ring water path 123 of the toilet discharges water to flush the toilet ring surface, and when the switching structure is in the second water outlet state, the main flushing water path 132 of the toilet discharges water to flush the water seal at the bottom of the toilet, so that a strong siphon is generated in the sewage pipe to discharge the dirt in the toilet. Among them, the water supply mechanism is a water pump 41 or a solenoid valve or a water inlet valve or a flow increasing valve, and the water source of the water supply mechanism can be the water stored in the toilet water tank 40 or directly connected to the municipal tap water supply.

[0057] Cooperate Figures 2 to 4 As shown, in this embodiment, the main body 10 of the switching structure is designed as follows: the main body 10 is mainly made of plastic, and the main body 10 includes a main shell 12 and a lower cover 13, the lower cover 13 is arranged at the lower end of the main shell 12 and cooperates with the main shell 12 to form the switching chamber 11, the water inlet 121 and the first water outlet 122 are arranged on the main shell 12, and the second water outlet 131 is arranged on the lower cover 13.

[0058] The lower cover 13 is cylindrical with an open top, and the switching member 20 is assembled in the lower cover 13. Then, the top of the lower cover 13 is fixed to the bottom of the main shell 12 by snapping. The lower cover 13 and the main shell 12 enclose the switching chamber 11. A sealing ring is provided between the lower cover 13 and the main shell 12 to prevent water leakage in the switching chamber 11.
