Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purifiers, in particular to a flow regulating valve for a water purifier. BACKGROUND

[0002] A water purifier, especially an instant water purifier, generally has a flow regulating valve for adjusting the temperature of normal water. The flow regulating valve can adjust the water flow of normal water entering the heating device to control the water temperature. By switching between different flows through the flow regulating valve, the user's use demand for different water temperatures can be met.

[0003] In the prior art, a movable valve core and a static valve core are provided, and flow holes are formed on the movable valve core and the static valve core. When it is necessary to adjust the flow, the movable valve core is rotated so that the flow holes on the movable valve core gradually correspond to the flow holes on the static valve core, thereby controlling the flow through the corresponding degree of the flow holes. When the flow holes on the movable valve core and the static valve core completely correspond, the adjustment from small flow to large flow is realized. This design cannot quickly switch between small flow and large flow, so the adjustment speed is slow. If the user needs normal water, a long adjustment time is required, which leads to poor user experience. CONTENT OF THE UTILITY MODEL

[0019] In one of the embodiments, the part of the driving assembly extending into the valve cavity is in sealing connection between the part and the inner wall of the valve cavity.

[0020] In one of the embodiments, the driving assembly comprises a driving member and a rotating shaft, the driving member is mounted to the valve body, one end of the rotating shaft is connected to the driving member, the other end of the rotating shaft extends into the valve cavity and is in circumferential limiting connection with the dynamic valve core, and the rotating shaft is in sealing connection with the inner wall of the valve cavity.

[0038] Referring to Figures 1 to 5 The present application provides a flow regulating valve 100 for water purifier, which is used for controlling the flow of fluid during fluid delivery, and can be applied to the fields of water purification, chemical reaction, pharmacy and other fields requiring fluid delivery. In the present application, the flow regulating valve 100 for water purifier is applied to the field of water purification, and is mainly used for instant water purifier.

[0039] Specifically, the flow regulating valve 100 for water purifier comprises a valve body 10, a static valve core 20 and a dynamic valve core 30, the valve body 10 has an inlet 11, an outlet 12 and a valve cavity 13, the inlet 11 and the outlet 12 can be communicated through the valve cavity 13; the static valve core 20 is installed in the valve cavity 13 and is sealingly connected with the inner wall of the valve cavity 13, and the static valve core 20 is provided with a first main flow hole 21 and at least one first auxiliary flow hole 22, the first main flow hole 21 and the first auxiliary flow hole 22 are arranged at intervals along the circumference of the valve cavity 13; the dynamic valve core 30 is rotatably installed in the valve cavity 13 and is provided with a second main flow hole 31 and a second auxiliary flow hole 32; the second main flow hole 31 and the second auxiliary flow hole 32 are arranged at intervals along the circumference of the valve cavity 13, and the second main flow hole 31 is matched with the first main flow hole 21, and the second auxiliary flow hole 32 is matched with the first auxiliary flow hole 22; wherein, with the rotation of the dynamic valve core 30, when the second main flow hole 31 is completely coincided with the first main flow hole 21, the second auxiliary flow hole 32 and the first auxiliary flow hole 22 correspond to each other and are communicated. Here, the inlet 11 is connected with the normal temperature water interface of the water purifier, and the outlet 12 is connected with the heating device in the water purifier. In this way, by arranging the first main flow hole 21 and the first auxiliary flow hole 22 on the static valve core 20 and the second main flow hole 31 and the second auxiliary flow hole 32 on the dynamic valve core 30, with the rotation of the dynamic valve core 30, the second main flow hole 31 gradually coincides with the first main flow hole 21 to realize the regulation of the flow, when the second main flow hole 31 is completely coincided with the first main flow hole 21, the second auxiliary flow hole 32 and the first auxiliary flow hole 22 correspond to each other and are communicated, which can realize the quick switching of small flow and large flow. Thus, the quick regulation of small flow and large flow can be realized under the condition of small rotation angle. In addition, since the relative rotation range of the dynamic valve core 30 and the static valve core 20 is small during the flow regulation, the wear degree of the dynamic valve core 30 and the static valve core 20 can be reduced, and the service life of the flow regulating valve 100 for water purifier can be improved.

[0040] As shown in Figure 1 and Figure 2 , the valve body 10 comprises a lower valve body 14 and an upper valve body 15, the upper valve body 15 is sealingly connected with the lower valve body 14 and surrounds the valve cavity 13; the inlet 11 is arranged on the upper valve body 15, the outlet 12 is arranged on the lower valve body 14; the static valve core 20 is sealingly connected with the lower valve body 14. In this way, by arranging the lower valve body 14 and the upper valve body 15 to be assembled together as the valve body 10, the internal structure can be installed first and then the upper and lower valve bodies 14 are connected during assembly, which is convenient for the assembly of the overall structure. Here, the upper valve body 15 and the lower valve body 14 can be sealed by arranging a sealing ring.

[0041] In the embodiment, the upper valve body 15 and the lower valve body 14 are screwed. In this way, the upper valve body 15 and the lower valve body 14 are screwed to realize detachable connection of the valve body 10 at a low cost, and when the water purifier flow regulating valve 100 needs to be repaired, the upper valve body 15 and the lower valve body 14 can be detached for repair of the internal structure.

[0042] In an embodiment, the first main flow hole 21 is arranged along the circumferential direction of the valve cavity 13. In this way, the flow of fluid is controlled by the first main flow hole 21, and when the movable valve core 30 rotates, the second main flow hole 31 gradually coincides with the first main flow hole 21 to realize accurate control of the flow.

[0043] As shown in Figure 4 and Figure 5 , the number of the first auxiliary flow holes 22 is multiple, and the multiple first auxiliary flow holes 22 are arranged along the circumferential direction of the valve cavity 13, the number of the second auxiliary flow holes 32 is equal to that of the first auxiliary flow holes 22, and each first auxiliary flow hole 22 is matched with a second auxiliary flow hole 32. In this way, by arranging multiple first auxiliary flow holes 22 and second auxiliary flow holes 32, when the second main flow hole 31 completely coincides with the first main flow hole 21, the multiple second auxiliary flow holes 32 and the multiple first auxiliary flow holes 22 correspond to each other and communicate, and by adjusting the number of the first auxiliary flow holes 22 and the second auxiliary flow holes 32, the value of the maximum flow can be adjusted to meet the demand of the water purifier flow regulating valve 100 for large flow and realize quick switching between small flow and large flow.

[0044] In an embodiment, the first auxiliary flow hole 22 is arranged along the radial direction of the valve cavity 13 and is in a long strip shape; and / or, the second auxiliary flow hole 32 is arranged along the radial direction of the valve cavity 13 and is in a long strip shape. Here, by arranging the first auxiliary flow hole 22 and the second auxiliary flow hole 32 in a long strip shape along the radial direction of the valve cavity 13, when the movable valve core 30 rotates, the first auxiliary flow hole and the second auxiliary flow hole 32 can quickly correspond, thereby further improving the speed of the water purifier flow regulating valve 100 in switching between small flow and large flow.

[0045] Optionally, the long strip-shaped first auxiliary flow hole 22 and the second auxiliary flow hole 32 can be a waist-shaped hole, a fan-shaped hole, a rectangular hole, etc. In the embodiment, the first auxiliary flow hole 22 and the second auxiliary flow hole 32 are both configured as a waist-shaped hole.

[0046] In an embodiment, along the axial direction of the valve cavity 13, the projection of the first main flow hole 21 on the static valve core 20 can be located in the second main flow hole 31. That is, the area of the second main flow hole 31 is greater than that of the first main flow hole 21, so that the first main flow hole 21 can have sufficient flow.

[0047] Preferably, the second main flow hole 31 is arranged in a fan shape.

[0048] As shown in Figures 3 to 5 The water purifier flow regulating valve 100 further comprises a driving assembly 40, which is mounted on the valve body 10 and part of which extends into the valve cavity 13 and is connected with the dynamic valve core 30 in the circumferential direction. The part of the driving assembly 40 extending into the valve cavity 13 is sealingly connected with the inner wall of the valve cavity 13. In this way, the driving assembly 40 rotates to drive the dynamic valve core 30 to rotate, thereby achieving flow regulation. At the same time, the driving assembly 40 is sealingly connected with the inner wall of the valve cavity 13, which can prevent water leakage in the valve cavity 13 and ensure the stability of the work.

[0049] In an embodiment, the driving assembly 40 comprises a driving member 41 and a rotating shaft 42. The driving member 41 is mounted on the valve body 10, one end of the rotating shaft 42 is connected with the driving member 41, and the other end extends into the valve cavity 13 and is connected with the dynamic valve core 30 in the circumferential direction. The rotating shaft 42 is sealingly connected with the inner wall of the valve cavity 13.

[0050] Further, the dynamic valve core 30 is provided with an annular extension section 33 facing the driving member 41. The extension section 33 is provided with a notch 331, and the rotating shaft 42 is provided with a limiting protrusion 421. The limiting protrusion 421 is clamped in the notch 331 and is limited in the circumferential direction of the valve cavity 13 by abutting against the wall surface of the notch 331. In this way, the circumferential limitation between the driving member 41 and the dynamic valve core 30 can be achieved.

[0051] Please refer to Figure 3 and Figure 4 The driving assembly 40 further comprises a resilient member 43, which is sleeved on the extension section 33. One end of the resilient member 43 abuts against the dynamic valve core 30, and the other end abuts against the rotating shaft 42. The resilient member 43 can provide a force in the axial direction of the valve cavity 13. On the one hand, the sealing between the rotating shaft 42 and the valve cavity 13 can be more reliable. On the other hand, the dynamic valve core 30 can be stably abutted against the static valve core 20, so that the relative movement between the two is more stable.

[0052] Here, the resilient member 43 can be a spring or a sleeve with elastic function.

[0053] The technical features of the above-described embodiments can be combined in any way. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0054] The above-described embodiments are merely illustrative of several embodiments of the present application, which are described in more detail and in a specific manner, but should not be construed as limiting the scope of the patent application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
