Detailed Description
The invention is further described below with reference to the drawings and specific examples.
Example 1
Referring to fig. 1-5, a water stop switching valve core comprises a valve core body 1, wherein a water inlet 11 is arranged on the side surface of the valve core body, and a water outlet 12 is arranged at the bottom of the valve core body; the water inlet 11 and the water outlet 12 are communicated to form a flow channel; the valve core body is provided with an accommodating cavity along the axial direction of the valve core body; the device also comprises an operating piece 2, a water stopping piece 3 and a water outlet switching piece 4 which are arranged in the accommodating cavity;
the operating member 2 includes a pressing water stop member 21 and a rotation switching member 22 which are provided independently of each other; the pressing water stop 21 moves along the axial direction of the accommodating cavity, and the tail end of the pressing water stop 21 is propped against the pressure relief hole 31 of the water stop 3 to seal or separate;
the water stop member 3 is a pressure cover and is provided with a water stop cavity 32, a fixed seat 33 is arranged at the bottom of the water stop cavity 32 and is fixedly connected with the bottom of the water stop cavity 32 to jointly enclose the water stop cavity 32; a sealing piece 34 is arranged on the fixed seat 33, and a water sealing part 13 which is close to the sealing piece 34 is arranged in the flow channel; the fixing seat 33 and the sealing piece 34 are provided with through holes 35 which are communicated with the water inlet 11 and the water stopping cavity 32 at corresponding positions; the fixing seat 33 is further provided with the pressure relief hole 31 which is communicated with the water outlet 12 and the water stopping cavity 32.
Therefore, when the water stop 21 is pressed to be sealed against the pressure release hole 31, water flows from the water inlet 11 into the water stop cavity 32 through the through hole 35; at this time, since the pressure release hole 31 is sealed, the water pressure above the sealing sheet 34 is greater than the water pressure below; the sealing piece 34 moves downwards to be propped against and sealed with the water sealing part 13 under the action of water pressure. So that the water flow cannot flow out of the water outlet 12 after passing through the flow channel, and water stop is realized.
When the water stop piece 21 is pressed to be separated from the pressure relief hole 31, water in the water stop cavity 32 originally flows into the flow channel from the pressure relief hole 31, the water pressure in the flow channel is larger than the water pressure of the water stop cavity 32, the sealing piece 34 moves upwards to be separated from the water sealing part 13 under the action of the water pressure, and water flows out of the water outlet 12 after entering the flow channel through the water inlet 11, so that water is introduced.
The water outlet switching piece 4 comprises a movable ceramic piece 41 and a fixed ceramic piece 42 which are arranged on the water outlet 12; the movable ceramic plate 42 is disposed in conjunction with the rotary switching member 22. The movable ceramic plate 41 is provided with a water outlet, and the fixed ceramic plate 42 is provided with two water outlets; the water outlet holes of the movable ceramic plate 41 are communicated with different water outlets on the fixed ceramic plate 42 by rotating the rotary switching piece 4, and different water outlets are selected to discharge water. The number of water outlets on the ceramic tile 42 may be 3 or more as required, which is a simple replacement in this embodiment, and will not be described in detail.
From the above, the pressing water stop 21 and the rotation switching member 22 are two completely independent components, and do not interfere with each other. Therefore, when the user switches from the water-through state to the water-stop state, the relative positions of the fixed ceramic plate 42 and the movable ceramic plate 41 are not changed, and when the user switches to the water-through state again, the water-out state can still be kept as the water-out of the last water-through state, the user does not need to repeatedly adjust, the use of the user is greatly facilitated, and the use experience is improved.
As can be seen from the above description, when the water is switched from water stop to water supply, the water is used to apply water pressure to the fixing seat 33 so as to drive the fixing seat 33 and the sealing piece 34 to move upwards. If the water pressure is relatively low, the water pressure is insufficient to drive the fixing seat 33 to move upwards, and the propping state of the sealing piece 34 and the water sealing part 13 cannot be released, so that the condition of 'low pressure opening' is formed, and the stability is not good enough.
To solve this, in the present embodiment, the pressing water stop 21 and the fixing seat 33 are provided with a lifting portion that abuts against each other; in the process of moving up the pressing water stop 21 along the axial direction, the lifting parts are propped against each other, so that the pressing water stop 21 drives the fixing seat 33 to move up. This ensures that the fixing seat 33 can be moved up in time in both the high-pressure and low-pressure states, ensuring the reliability of the water outlet state.
In order to realize the up-and-down movement of the pressing water stop 21, the pressing water stop 21 comprises a ball pen pressing mechanism 211 and a pressing rod 212 linked with the ball pen pressing mechanism, and the tail end of the pressing rod 212 is connected with a guide rod 213; the guide rod 213 has a drainage cavity 214 connected with the water-stopping cavity 32, one end of which is sleeved at the end of the pressure rod 212, and the other end of which is sleeved outside a push rod 215; the end of the push rod 215 is exposed to the outside of the press rod 212 and is connected to a sealing sleeve 216.
The user can move up and down the pressing stopper 21 by repeatedly pressing the ballpoint pen pressing mechanism 211. This part of the structure belongs to the prior art and will not be described in detail. The purpose of the drainage chamber 214 is that in the water stop condition, the drainage chamber 214 is also filled with water to balance most of the water pressure in the water stop chamber 32. Thus, the pressure of the water received by the pressure lever 212 and the sealing sleeve 216 is relatively small, and the force required for switching from water stop to water passage is relatively small.
On the other hand, in the water-stop state, the flexible sealing piece 34 is compressed when sealing with the water sealing part 13, so that the fixing seat 33 and the sealing piece are both sunken to a certain extent, and at this time, the sealing sleeve 216 may be separated from the pressure release hole 31, so that the valve core is not closed when in water-stop. In order to solve this problem, a compensating spring 217 with a compression amount is disposed in the drainage cavity 214, so as to apply a downward force to the ejector rod 215 and the sealing sleeve 216 at any time, so that the sealing sleeve can keep propping against the pressure release hole 31 when water is stopped, and further keep the valve core stable in a water stopping state.
The lifting part comprises a first propping block 218 arranged on the periphery of the guide rod 213 and a second propping block 331 arranged on the fixed seat 33; when the sealing sleeve 216 seals the pressure release hole 31 of the fixing seat 33, the second propping block 331 is located above the first propping block 218 and is located in the same vertical plane with the first propping block.
Example 2
Referring to fig. 6 to 8, this embodiment differs from embodiment 1 in that: the movable ceramic plate 41 and the fixed ceramic plate 42 are respectively provided with a water outlet hole; the water outlet area of the movable ceramic plate 41 and the fixed ceramic plate 42, which are overlapped, is changed by rotating the rotary switching piece 22, so that the water outlet quantity of the water outlet 12 is changed. The rest is the same as in example 1 and will not be described again.
Example 3
Referring to fig. 9-12, in this embodiment, the water outlet 12 and the water inlet 11 are respectively disposed on the side surface of the valve core body 1, and the water outlet 12 is located above the water inlet 11. And, the said pressing water stop 21 includes a ball pen pressing mechanism 211, and a movement rod 219 linked therewith; a seal ring 2191 is arranged at the end of the moving rod 219;
the water stopping cavity 32 is arranged below the water inlet 11, and the fixing seat 33 is arranged at the top end of the water stopping cavity 32; the moving rod 219 passes through the fixing seat 33 and extends into the water stopping cavity 32; when the pressing water stop 21 is at a low position, the moving rod 219 moves downwards along the axial direction to separate the sealing ring 2191 at the tail end of the moving rod from the pressure release hole 31; when the pressing water stop 21 is at the high position, the moving rod 219 moves upward in the axial direction to make the sealing ring 2191 at the end of the moving rod seal against the pressure release hole 31. Thus its water stop and water passage state is the reverse of that of example 1.
In this embodiment, the outer circumference of the moving rod 219 and the fixed seat are further provided with a pushing part in abutting fit; the pushing part is a first pressing block 2192 extending outwards along the axial direction from the outer periphery of the moving rod 219 and a second pressing block 332 on the fixed seat 33; when the moving rod 219 is located at the water stop position, the first pressing block 2192 is located above the second pressing block 332; when the moving rod 219 moves down from the water stop position to the water passing position, the first pressing block 2192 and the second pressing block 332 are pressed against and pushed, and the generated pushing force moves the fixing seat 33 down from the water stop position to the water passing position, so that no matter the water pressure is high or low, the fixing seat 33 can be opened in time when the fixing seat needs to be opened.
In this embodiment, the structure of the water outlet switching member 4 in embodiment 1 or 2 may be selected, and the distance is the same as that of embodiments 1 and 2, and will not be described again. The only difference is that in this embodiment, the stationary ceramic plate 42 is placed on the side of the movable ceramic plate 41 close to the water inlet.
The above description is illustrative of the embodiments using the present teachings, and is not intended to limit the scope of the present teachings to any particular modification or variation of the present teachings by those skilled in the art.
