[0002] At present, the throttle holes in the wastewater solenoid valves used in water purifiers are generally small in diameter to achieve the throttling function. The characteristics of the water purifier determine that after the water purifier has filtered and purified the water, the inorganic salt content in the remaining wastewater is relatively high. The growth of inorganic salt crystal nuclei can easily cause the throttle holes of the wastewater solenoid valve to be blocked, which in turn causes the wastewater solenoid valve to become ineffective after being blocked, making the water purifier unable to be used normally. Summary of the invention

[0028] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] The valve in this embodiment is specifically a wastewater valve used in a water purifier. The wastewater valve used in the prior art water purifier mostly adopts a conventional valve, in which the throttling function is realized by a throttling hole opened in the valve cavity 8, and the size of the throttling hole is generally less than 10mm, which has the advantages of simple structure and low manufacturing cost. However, when the conventional valve is used as a wastewater valve in a water purifier, since the inorganic salt content in the wastewater in the water purifier is much higher than that in ordinary water, the throttling hole of the conventional valve in the water purifier is easily blocked, affecting the realization of the normal function of the water purifier.

[0031] like Figures 1 to 3 As shown, in view of the above problems existing in the prior art, the valve in this embodiment mainly includes: a valve body 5, a valve core 4 and a pressure reducing and throttling structure. The valve body 5 in this embodiment is provided with a valve cavity 8, the valve core 4 is arranged in the valve cavity 8, and can reciprocate in the valve cavity 8, one end of the pressure reducing and throttling structure is connected with the valve cavity 8, and the other end is used to communicate with the outside of the valve; wherein, the pressure reducing and throttling structure in this embodiment includes a throttling channel 13, and a movable body movably arranged in the throttling channel 13, and a throttling gap for throttling is formed between the movable body and the throttling channel 13.

[0032] Furthermore, the valve in this embodiment is provided with a pressure reducing throttling structure having one end connected to the valve cavity 8 and the other end used to communicate with the outside of the valve. At the same time, the pressure reducing throttling structure includes a throttling channel 13 and a movable body movably arranged in the throttling channel 13. A throttling gap for throttling is formed between the movable body and the throttling channel 13, so that when the valve throttles through the throttling gap between the movable body and the throttling channel 13, the movable body can move in the throttling channel 13 under the action of the water flow, thereby effectively avoiding the formation of inorganic salt crystals in the throttling gap, thereby avoiding or at least alleviating the problem of blockage.

[0033] Specifically, the movable body in this embodiment is a rolling ball 2 that is movably arranged in the throttling channel 13. The gap between the rolling ball 2 and the throttling channel 13 can be controlled within a certain range. When water flows through, the turbulent water flow in the water flow will play a throttling back pressure role. The rolling ball 2 will move or rotate with the change of water pressure and the edge of the water flow, thereby effectively preventing the wastewater valve from being blocked due to the crystallization of inorganic salts, thereby ensuring the normal operation of the wastewater valve.

[0034] Of course, in addition to the rolling ball 2, the movable body can also be an ellipsoid, a cylinder, etc., which can move under the action of water flow and can form a throttling gap with the throttling channel 13.

[0035] As for how the pressure reducing throttling structure is connected with the valve chamber 8, the throttling channel 13 in the present embodiment can be arranged in the valve chamber 8, and the pressure reducing throttling structure also includes a first water hole 14 connecting the throttling channel 13 and the valve chamber 8. When throttling is required, the water in the valve chamber 8 enters the throttling channel 13 through the first water hole 14 and is throttled through the throttling gap.

[0036] In this embodiment, the aperture of the first water hole 14 is smaller than the aperture of the throttling channel 13, thereby preventing the rolling ball 2 from entering the first water hole 14 and blocking the first water hole 14. The extension direction of the first water hole 14 is perpendicular to the extension direction of the throttling channel 13, thereby the movement of the movable body is not likely to affect the flow of water in the first water hole 14.

[0037] Specifically, the valve in this embodiment also includes a drainage cavity 7 with a drainage hole 6, the drainage cavity 7 is formed in the valve cavity 8, and is connected to the valve cavity 8 through an opening, and the valve core 4 reciprocates in the valve cavity 8 to open or close the opening on the drainage cavity 7. The pressure reducing throttling structure also includes a second water hole 15 connecting the throttling channel 13 and the drainage cavity 7, and the second water hole 15 is used to connect the throttling channel 13 with the drainage hole 6 in the drainage cavity 7, thereby realizing that the water after throttling is discharged to the outside of the valve through the drainage hole 6. The aperture of the second water hole 15 is smaller than the aperture of the rolling ball 2, thereby preventing the rolling ball 2 from affecting the water flow of the second water hole 15.

[0038] The valve in this embodiment is specifically a solenoid valve. When the valve is powered on, water enters the valve from the water inlet. The valve core 4 has a silicone head 3. The silicone head 3 moves upward as the valve core 4 moves upward after the electromagnetic coil is powered on. The water entering the valve flows directly out of the valve from the drainage cavity 7 through the drainage hole 6 under the water pressure. When the solenoid valve loses power, the valve core 4 moves downward under the elastic force of the reset spring, and the silicone head 3 blocks the opening of the drainage cavity 7 under the action of the reset spring. At this time, the water cannot be discharged from the drainage hole 6, but enters the throttling channel 13 through the first water hole 14, passes through the throttling gap between the throttling channel 13 and the rolling ball 2, and then enters the drainage cavity 7 from the second water hole 15 for discharge.

[0039] Preferably, the valve in this embodiment also includes a plug 1 detachably mounted on the valve body 5. When the plug 1 is removed, the throttling channel 13 can be connected to the outside of the valve. In this way, even under extremely harsh water conditions, such as failure of the front-end filter device of the water purifier, resulting in impurities in the water clogging the solenoid valve, the valve in this embodiment can still disassemble the plug 1, and then take out the plug 1 to clear the throttling channel 13, which facilitates the maintenance of the valve.

[0040] This embodiment also provides a device with a valve, including the valve as described above. Therefore, the advantages possessed by the above-mentioned valve should also be possessed by the device with a valve in this embodiment, which will not be described in detail here.

[0041] In this embodiment, the device having a valve may be a water purifier, a drinking fountain, etc.

[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
