DETAILED DESCRIPTION
[0046] In order to make the technical problems, technical schemes and beneficial effects of the utility model clearer and more understandable, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.
[0047] Please refer to Figures 1 to 12 A mechanical switching valve comprises a switching valve body 1, a blocking piece 2 and a self-locking piece 3, wherein,
[0048] The switching valve body 1 is provided with an inner cavity 11, a water inlet 12, a first water outlet 13 and a second water outlet 14. The water inlet 12 and the first water outlet 13 are both located at the lower part of the inner cavity 11, and the second water outlet 14 is located at the upper part of the inner cavity 11. Preferably, the switching valve body 1 is further provided with a water inlet channel 15 communicating with the water inlet 12, and the water inlet channel 15 comprises a water passing section extending upward and then winding downward, and the highest point of the water passing section is higher than the second water outlet 14, so that the siphon effect can be avoided.
[0049] The blocking piece 2 is movably installed in the inner cavity 11 and is provided with a first blocking part 21 and a second blocking part 22 at the lower part and the upper part respectively, which can be used for blocking the first water outlet 13 and the second water outlet 14 respectively, and the self-locking piece 3 is swingably installed in the cavity.
[0050] In an embodiment, the water inlet 12 and the first water outlet 13 are arranged at the two sides of the inner cavity 11 respectively, and the first blocking part 21 is located at the lower side of the outer peripheral part of the blocking piece 2. The second water outlet 14 is located at the top of the inner cavity 11, and the second blocking part 22 is located at the top of the blocking piece 2, which can better utilize the upward buoyancy to form a better sealing effect. In addition, the guiding structure 4 in the vertical direction is arranged between the inner wall of the inner cavity 11 and the outer peripheral part of the blocking piece 2, which can provide accurate guidance for the movement of the blocking piece 2.
[0051] In order to make better use of water power, in one embodiment, the bottom of the blocking member 2 is provided with an inner recess 23 which is open towards the water inlet 12. The water inlet 12 is always at the bottom of the inner recess 23. When the water inlet 12 is filled with water, the water power can push the blocking member 2 upwards, thus improving the sensitivity and speed of the upward movement of the blocking member 2. In another embodiment, the bottom and the periphery of the blocking member 2 are provided with a clearance 26. This can avoid the blocking member 2 being adsorbed to the inner wall of the inner cavity 11 and thus being difficult to move. Please refer to Figure 13 and Figure 14 .
[0052] In one embodiment, the blocking member 2 is provided with a first buoyancy chamber 24 which is open upwards. In the initial stage of water filling, the first buoyancy chamber 24 provides buoyancy, thus improving the sensitivity and speed of the upward movement of the blocking member 2. When the water level reaches the first buoyancy chamber 24, in the water-off state, the water in the first buoyancy chamber 24 can make the blocking member 2 fall quickly. In the case that there is still water in the inner cavity 11, the blocking member 2 can release the self-locking member 3, thus enabling the self-locking member 3 to switch to the second position by using the buoyancy of the water, thereby improving the speed of switching of the self-locking member 3 from the first position to the second position and improving the sensitivity of the switching valve. Preferably, the self-locking member 3 is swingably mounted between the horizontal rotating shaft 31 and the inner cavity 11 and swingably arranged in or on the top of the first buoyancy chamber 24, thus avoiding space waste and reducing the size of the mechanical switching valve.
[0053] On the basis of the above embodiments, regarding the limiting structure between the blocking member 2 and the self-locking member 3, in one embodiment, the blocking member 2 is provided with a first limiting portion 25 which is upward, and the self-locking member 3 is provided with a second limiting portion 32 which is downward. When the self-locking member 3 is in the first position, the first limiting portion 25 and the second limiting portion 32 are opposite to each other. When the self-locking member 3 is in the second position, the first limiting portion 25 and the second limiting portion 32 are staggered. In addition, the self-locking member 3 is provided with a second buoyancy chamber 33 which is open downward. When the water level reaches the second buoyancy chamber 33, the self-locking member 3 can be provided with buoyancy, thus being able to switch from the first position to the second position.
[0054] In use, the mechanical switching valve has the following states:
[0055] Initial state: there is no water in the inner cavity 11, the blocking member 2 falls to the bottom of the inner cavity 11, the first blocking portion 21 seals the first water outlet 13, the second blocking portion 22 does not seal the second water outlet 14, and the second water outlet 14 and the water inlet 12 are communicated. The self-locking member 3 is in the first position by gravity and limits the upward movement of the blocking member 2, i.e. blocks the track of the upward movement of the blocking member 2.
[0056] When the water inlet 12 is first supplied with water, the inner cavity 11 is supplied with water, the blocking piece 2 floats upwards and abuts against the self-locking piece 3, and cannot continue to move upwards, so that the first blocking part 21 maintains the state of blocking the first water outlet 13, and the second water outlet 14 is supplied with water and can be used as circle water.
[0057] When the water inlet 12 is first stopped with water, the inner cavity 11 is drained through the gap between the first blocking part 21 and the first water outlet 13, the blocking piece 2 moves downwards and releases the self-locking piece 3, and the self-locking piece 3 is floated to the second position in the residual water in the inner cavity 11 and releases the limiting of the upward movement of the blocking piece 2.
[0058] When the water inlet 12 is secondly supplied with water, the blocking piece 2 floats upwards and blocks the second water outlet 14 through the second blocking part 22, the first blocking part 21 opens the first water outlet 13, and the first water outlet 13 is supplied with water and can be used as main flushing water.
[0059] When the water inlet 12 is secondly stopped with water, the water in the inner cavity 11 is completely drained through the first water outlet 13, and the blocking piece 2 and the self-locking piece 3 return to the initial state.
[0060] When the water inlet 12 is thirdly supplied with water, the second water outlet 14 is supplied with water and can be used as supplementary water.
[0061] The mechanical switching valve provided by the utility model, through setting the blocking piece 2 that floats upwards and downwards and the self-locking piece 3 that can adjust the state through gravity and buoyancy, different blocking states of the first water outlet 13 and the second water outlet 14 of the switching valve can be formed at different water supply and water stop time, so that three-stage water can be realized only through mechanical structure, the traditional electric valve can be replaced, and electricity is not needed in use, and power failure is not feared.
