Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined arbitrarily with each other.

[0033] An embodiment of the present utility model provides a water outlet valve 100, including: a valve body 1 and a floating member 2 disposed inside the valve body 1, and the floating member 2 can switch the water inlet and outlet of the valve body 1.

[0034] As Figure 1 - Figure 2 、 Figure 4 - Figure 5 shown, the valve body 1 is provided with a valve cavity 10, and the inner wall of the valve cavity 10 is provided with a first water inlet 101, a second water inlet 102 and a water outlet 103. The opening directions of the first water inlet 101 and the second water inlet 102 are opposite to each other, so that the water flow directions entering the valve cavity 10 from the first water inlet 101 and the second water inlet 102 are opposite to each other.

[0035] The floating member 2 is disposed in the valve cavity 10 and has a first working state of blocking the first water inlet 101 (see Figure 5 ) and a second working state of blocking the second water inlet 102 (see Figure 6 ). The floating member 2 is arranged such that under the action of the water flow entering the first water inlet 101 or the second water inlet 102, it can move in the valve cavity 10 in the relative direction of the first water inlet 101 and the second water inlet 102 to switch between the first working state and the second working state (see Figure 5 the direction indicated by the arrow), so as to realize the on-off relationship switching of the first water inlet valve port 104, the second water inlet valve port 105 and the water outlet valve port 106.

[0036] In the embodiment of the present utility model, the water outlet valve 100 realizes the on-off control of the two first water inlet ports 101 and the second water inlet port 102 by arranging a floating member 2 capable of moving under the action of water flow in the valve cavity 10, without the need for additional power, saving costs, having low noise, and having a simple and reliable structure.

[0037] In addition, the water outlet valve 100 of the present utility model realizes the on-off control of the first water inlet port 101 and the second water inlet port 102 only through the action of water flow by designing the directions of the first water inlet port and the second water inlet port, without the need for the cooperation of its own gravity, so the installation requirements are low and the adaptability is strong.

[0038] As Figure 4 shown, the floating member 2 has opposite first water stop surfaces 201 and second water stop surfaces 202 along the movement direction. In the first working state, the first water stop surface 201 of the floating member 2 blocks the first water inlet port 101; in the second working state, the floating member 2 blocks the second water inlet port 102.

[0039] In an exemplary embodiment, the floating member 2 can also be provided with water stop surfaces on its circumferential side to cooperate with the inner wall of the valve cavity 10 to realize water stop.

[0040] As Figure 4 、 Figure 5 shown, the valve cavity 10 is provided with a guiding cavity 10a communicating the first water inlet port 101 and the second water inlet port 102. The floating member 2 is at least partially arranged in the guiding cavity 10a and can move in the guiding cavity 10a under the action of the water flow entering the first water inlet port 101 or the second water inlet port 102.

[0041] The embodiment of the present utility model can guide the floating movement of the floating member 2 by arranging the guiding cavity 10a, ensuring the reliability of the movement of the floating member 2.

[0042] The diameter of the guiding cavity 10a in the embodiment of the present utility model is larger than the diameters of the first water inlet port 101 and the second water inlet port 102. The opposite two wall surfaces of the guiding cavity 10a along the movement direction of the floating member 2 respectively form a first sealing surface A and a second sealing surface B.

[0043] In the first working state, the first water stop surface 201 of the floating member 2 cooperates with the first sealing surface A to block the first water inlet port 101; in the second working state, the floating member 2 cooperates with the second sealing surface B to block the second water inlet port 102.

[0044] In the embodiment of the present utility model, by setting the diameter of the guiding cavity 10a to be larger than the diameters of the first water inlet 101 and the second water inlet 102, a first sealing surface A and a second sealing surface B are thus formed, so that the sealing area with the first water stopping surface 201 and the water stopping surface 202 of the floating member 2 can be increased, and the sealing effect can be enhanced. Therefore, the water outlet valve 100 of the embodiment of the present utility model can be applied to a more precise sealing environment.

[0045] In an exemplary embodiment, the diameter of the guiding cavity 10a may also be equal to the diameters of the first water inlet 101 and the second water inlet 102, and the circumferential sides of the floating member 2 are sealingly fitted with the inner wall of the circumferential side of the guiding cavity 10a to block the first water inlet 101 and the second water inlet 102.

[0046] As Figure 3 shown, the floating member 2 includes a blocking portion 20, and a first blocking gasket 21 and a second blocking gasket 22 provided on opposite sides of the blocking portion 20 along the movement direction. The first blocking gasket 21 has a first water stopping surface 201, and the second blocking gasket 22 has a second water stopping surface 202.

[0047] The blocking portion 20 is provided with a water stopping ring rib 203, and a first installation groove 204 and a second installation groove 205 provided on both sides of the water stopping ring rib 203. The first blocking gasket 21 is installed in the first installation groove 204 and abuts against the water stopping ring rib 203; the second blocking gasket 22 is installed in the second installation groove 205 and abuts against the water stopping ring rib 203. The first blocking gasket 21 and the second blocking gasket 22 are in contact with the water stopping ring rib 203, enhancing the sealing effect, preventing water leakage, and at the same time increasing the sealing strength.

[0048] As Figure 5 shown, the valve body 1 further includes a first water inlet flow channel 11, a second water inlet flow channel 12, and a water outlet flow channel 13 that are communicated with the first water inlet 101, the second water inlet 102, and the water outlet 103. The floating member 2 includes an extension portion 23 connected to the blocking portion 20, and the first water inlet flow channel 11 or the second water inlet flow channel 12 is provided with a limiting cavity 110 that cooperates with the extension portion 23 for sliding. The limiting cavity 110 not only has a guiding function, but also can keep the floating member 2 from falling off.

[0049] In the embodiment of the present utility model, the blocking portion 20 and the extension portion 23 are integrally formed, which is simple to manufacture. Of course, the blocking portion 20 and the extension portion 23 can also be separately installed, which is not limited herein.

One ends of the first water inlet flow channel 11, the second water inlet flow channel 12 and the water outlet flow channel 13 are communicated with the first water inlet valve port 104, the second water inlet valve port 105 and the water outlet valve port 106, and the other ends are communicated with the first water inlet 101, the second water inlet 102 and the water outlet 103.

[0051] As Figure 2 shown, the valve body 1 includes a first valve body 1a and a second valve body 1b assembled in the relative direction of the first water inlet 101 and the second water inlet 103. The first valve body 1a is provided with a first water inlet flow channel 11, and the second valve body 1b is provided with a second water inlet flow channel 12. The valve cavity 10 is formed after the first valve body 1a and the second valve body 1b are assembled for installing, replacing and maintaining the floating member 2.

[0052] As Figure 4 、 Figure 5 shown, in the drawings of this embodiment, the second water inlet flow channel 12 and the water outlet flow channel 13 are designed side by side, and the water inlet direction of the second water inlet 103 is opposite to the water outlet direction of the water outlet 103. The water outlet flow channel 13 in the drawings of this embodiment is arranged in the second valve body 1b. Of course, the water outlet flow channel 13 can be designed arbitrarily. Specifically, it can be designed according to the actual situation and is not limited here.

[0053] When the water outlet valve 100 of the embodiment of the present utility model works, as Figure 4 shown, in the first working state: water flows in from the second water inlet valve port 105 and through the second water inlet 101. The extension part 23 of the floating member 2 is limited in the first water inlet flow channel 11, and the blocking part 20 of the floating member 2 is located in the guiding cavity 10a. Driven by the water flow, the floating member 2 moves towards the first water inlet 101 until the first sealing gasket 21 fits against the first sealing surface A to block the first water inlet 101. At this time, the second water inlet 102 is opened, and the second water inlet 102 and the water outlet 103 are communicated.

[0054] As Figure 5 shown, in the second working state: water flows in from the first water inlet valve port 104 and through the first water inlet 102. Driven by the water flow, the floating member 2 moves towards the second water inlet 102 until the second sealing gasket 22 fits against the second sealing surface B to block the second water inlet 10. At this time, the first water inlet 101 is opened, and the first water inlet 101 and the water outlet 103 are communicated.
