Description

Technical Field

[0001] This utility model relates to the field of valve plate structure, specifically a valve core assembly for non-equal hot and cold water regulation. Background Technology

[0002] Currently, many valve cores on the market use ceramic valve plates to regulate and control the outlet water temperature. The valve core contains a moving valve plate and a fixed valve plate. The fixed valve plate has cold water inlet, hot water inlet, and outlet. The moving valve plate has a connecting channel, one end of which is always connected to the outlet. By adjusting the position of the connecting channel, the other end can be connected to both the cold water inlet and the hot water inlet simultaneously or separately. The outlet water temperature can be controlled by adjusting the overlap area between the connecting channel and the cold and hot water inlets. However, existing temperature control valve cores have the following problems:

[0003] Within the temperature adjustment range suitable for human comfort, the rotation angle of the moving valve is relatively small. The temperature adjustment range refers to the range where the outlet water temperature is close to human body temperature during the rotation of the moving valve (generally 37±~3℃ in actual use). The moving valve adjusts most frequently within this range, and the water output within this range is mostly used directly for showering, requiring a high degree of accuracy in the outlet water temperature.

[0004] The corresponding rotation angle of the moving valve disc within the valve core's temperature adjustment range is approximately 15°. The rotation angle of the moving valve disc corresponds to a large temperature range; for every certain degree of rotation, the outlet temperature of the mixed water will change significantly, resulting in poor temperature adjustment accuracy of the valve core within the main temperature adjustment range. For example... Figure 1 As shown, this is a common fixed valve structure, including a first inlet 3, a second inlet 4, and an outlet 5. The first inlet 3 and the second inlet 4 are symmetrical. The temperature is changed by adjusting the moving valve to alter the opening and closing of the first inlet 3 and the second inlet 4. This means that even a slight adjustment to the moving valve can cause a significant change in the outlet water temperature, making it difficult for the user to fine-tune the outlet water temperature to achieve their desired result. Utility Model Content

[0005] The purpose of this invention is to provide a valve core assembly for non-equal hot and cold water regulation, which solves the problem of poor temperature regulation accuracy in the prior art by optimizing the water inlet.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve core assembly for non-equal hot and cold water regulation, comprising:

[0007] The fixed valve plate includes a first inlet, a second inlet, and an outlet; wherein the first inlet is a hot water inlet and the second inlet is a cold water inlet.

[0008] A movable valve plate rotates in conjunction with a fixed valve plate, and the movable valve plate is provided with a connecting groove that connects to the first inlet, the second inlet and the outlet.

[0009] The water outlet surfaces of the first and second inlets are wide at both ends and narrow in the middle.

[0010] As a further improvement to the above technical solution:

[0011] The first and second entrances are symmetrically arranged.

[0012] A first baffle plate is provided on the first inlet and a second baffle plate is provided on the second inlet. The upper surfaces of the first and second baffle plates are flush with the contact surface on the fixed valve plate.

[0013] An enlarged opening is provided on the side of the first and second entrances that are close to each other.

[0014] The lower parts of the first and second water-blocking plates are chamfered.

[0015] An oil storage chamber is provided on the contact surface between the fixed valve plate and the moving valve plate.

[0016] This utility model also discloses a valve core with precise temperature adjustment, including a housing, a base, a control handle, and a chuck. It also includes the aforementioned valve core assembly for non-uniform hot and cold water regulation. A fixed valve plate and a movable valve plate are installed between the chuck and the base. The fixed valve plate and the base are circumferentially fixed, and the movable valve plate and the chuck are circumferentially fixed. A sealing element is provided between the fixed valve plate and the base. A rotating seat is fitted around the control handle, rotatably mounted on the upper end of the housing. The control handle is oscillating within the rotating seat. A slot is provided at the upper end of the chuck, and the lower end of the control handle is located within the slot.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Non-equal hot and cold water regulation, wider temperature control range: By designing the first and second inlets of the fixed valve plate with a structure that is wide at both ends and narrow in the middle, non-equal water intake is achieved. This design changes the problem of large water intake and small temperature control range caused by the traditional equal-width inlet structure, allowing users to adjust the hot and cold water ratio more precisely and obtain a wider temperature control range corresponding to the adjustment angle, meeting the personalized water temperature needs of different users.

[0019] More precise adjustment and easier operation: Due to the non-uniform water inlet design, this valve core assembly requires a larger rotation angle to achieve the same temperature change. This means that the sensitivity of temperature changes to the rotation angle is reduced, allowing users to make fine adjustments more easily and thus control the outlet water temperature more precisely, avoiding large fluctuations in water temperature caused by minor operations.

[0020] To ensure overall flow and avoid abnormal water output: an enlarged opening is set on the side where the first and second inlets are close to each other, ensuring that the overall water flow is still sufficient even when a baffle is set, thus avoiding problems such as abnormal water output or insufficient flow caused by local water flow obstruction.

[0021] Excellent lubrication and sealing performance: A sunken oil reservoir is provided on the contact surface between the stationary valve plate and the moving valve plate, which helps to store lubricant, reduce friction, make the moving valve plate rotate more smoothly, and extend its service life. At the same time, a seal is provided between the stationary valve plate and the base to ensure good sealing performance and prevent water leakage.

[0022] In summary, this utility model, through non-equal water inlet design, refined structural optimization, and reasonable component layout, achieves a wider temperature adjustment range, more precise temperature control, smoother water flow, and more convenient operation, thereby improving the performance of the valve core assembly and the user experience.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figure 1 As shown, this is the structure of the fixed valve plate in the prior art. The existing moving valve plate has a water inlet with a uniform width, which results in a larger water inflow and a smaller temperature adjustment range.

[0038] like Figures 2 to 7 As shown, the valve core assembly for non-equal hot and cold water regulation in this embodiment includes:

[0039] The fixed valve plate 2 includes a first inlet 3, a second inlet 4, and an outlet 5;

[0040] The movable valve plate 1 rotates and cooperates with the fixed valve plate 2. The movable valve plate 1 is provided with a connecting groove 6 that connects to the first inlet 3, the second inlet 4 and the outlet 5.

[0041] Among them, the water outlet surfaces of the first inlet 3 and the second inlet 4 are wide at both ends and narrow in the middle.

[0042] The first entrance 3 and the second entrance 4 are symmetrically arranged.

[0043] A first baffle plate 31 is provided on the first inlet 3 and a second baffle plate 41 is provided on the second inlet 4. The upper surfaces of the first baffle plate 31 and the second baffle plate 41 are flush with the contact surface on the fixed valve plate 2.

[0044] An enlarged opening 34 is provided on the side of the first inlet 3 and the second inlet 4 that are close to each other. Compared with the existing moving valve plate, the enlarged opening 34 here can ensure the overall flow rate and avoid the phenomenon of water output being affected by the presence of a water baffle.

[0045] The lower parts of the first water-blocking plate 31 and the second water-blocking plate 41 are chamfered. The chamfer design allows the water to flow smoothly and avoids water flow impact.

[0046] An oil reservoir 7 is provided on the contact surface between the stationary valve plate 2 and the moving valve plate 1. The oil reservoir 7 is a sunken design with a depth of 0.1-0.3 mm. The oil reservoir is filled with lubricating oil, which helps the rotation between the stationary valve plate 2 and the moving valve plate 1.

[0047] like Figure 8 The diagram shows a comparison between this valve core assembly and existing technologies. Under the same temperature change, this valve core assembly rotates 33°, while the existing technology rotates only 15°. This demonstrates that this valve core assembly is easier to adjust and facilitates accurate temperature control. A larger rotation angle corresponds to the same temperature change, meaning a smaller temperature change per unit angle (e.g., 33° corresponds to 7℃, approximately 4.7° per degree Celsius; 15° corresponds to 7℃, approximately 2.1° per degree Celsius), thus allowing for more precise adjustment.

[0048] like Figure 9 As shown, the precisely temperature-adjustable valve core of this embodiment includes a housing 13, a base 14, a control handle 15, and a chuck 16. A fixed valve plate 2 and a movable valve plate 1 are installed between the chuck 16 and the base 14. The fixed valve plate 2 and the base 14 are circumferentially fixed, and the movable valve plate 1 and the chuck 16 are circumferentially fixed. A sealing element is provided between the fixed valve plate 2 and the base 14. A rotating seat 17 is sleeved on the outside of the control handle 15. The rotating seat 17 is rotatably mounted on the upper end of the housing 13, and the control handle 15 is oscillatingly disposed within the rotating seat 17. A slot 18 is provided at the upper end of the chuck 16, and the lower end of the control handle 15 is located within the slot 18.

[0049] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
