Problems solved by technology

Under this structure, because the area of ​​the circlip is small, and the water pressure evenly covers the diaphragm, it is difficult to drive the entire diaphragm to move upwards, so it is difficult to accurately adjust the flow rate. Large, but the adjustment effect at the later stage of the stroke is very inconspicuous, which does not meet the user's flow adjustment needs.

Embodiment 1

[0074] First reference Figure 1-4 , The multifunctional valve core 1 of this embodiment includes a valve housing 10 in which a flow regulating component 20 and a water stop component 30 are provided.

[0075] The flow regulating assembly 20 includes a rotary actuator 21, a receiving seat 22, and a fixed seat 23. The receiving seat and the fixed seat have a first water outlet 221 and a second water outlet 231, respectively. The two water outlets cooperate to be assembled A first water flow channel 24 with a variable cross-sectional area is formed in the receiving seat and the fixing seat. The rotating actuating member 21 is arranged in conjunction with the receiving seat 22 to drive it to rotate relative to the fixed seat 23, thereby controlling the flow cross section overlapped by the first water passage and the second water passage to change accordingly. In this embodiment, the rotary actuator 21 and the receiving seat 22 are connected by buckles and claws.

[0076] At the same ...

Embodiment 2

[0099] reference Figure 14-20 The main difference between this embodiment and the first embodiment is that the eccentric relationship between the corresponding water passages of the receiving seat 22 and the fixed seat 23 is exchanged. In the specific structure, the receiving seat and the fixing seat are still integrated. The lower end of the receiving seat 22 is provided with a protruding post 223. The bottom of the protruding post is hollowed out with a through hole connected upward to the third water outlet 222, and the through hole constitutes The first water outlet 221. The through hole 221 has a constant cross-sectional area along the inflow direction of the water flow, and a cross section perpendicular to the direction of the water flow does not have the characteristic that the rate of change of the cross-sectional area changes monotonously along the direction of the rotation stroke, so its rotation relative to the fixed seat 23 always Have the same rate of change in cr...

Embodiment 3

[0105] reference Figure 21-25 The main difference between this embodiment and Embodiment 1 is that the receiving seat 22 and the fixing seat 23 are both separated. In a specific structure, the receiving base 22 includes a continuous receiving upper base 223 and a movable ceramic sheet 224, and the fixed base 23 includes a fixed base 232 and a fixed ceramic sheet 233 that are fixed to each other. The movable ceramic sheet 224 is provided with a first flow hole to form the first water outlet 221; the fixed ceramic sheet 233 is provided with a second flow hole to form the second water outlet 231.

[0106] The hole edge of the first flow hole 221 is formed by connecting and transitioning two arcs with the same radius of curvature, and the hole edge of the second flow hole 231 is formed by connecting and transitioning two arcs with different radii of curvature. Therefore, through the foregoing analysis, it can be easily obtained: the structure of the first flow hole 221 is similar to...

Abstract

The invention discloses a multi-function valve core for regulating flow and stopping water. The multi-function valve core for regulating flow and stopping water comprises a flow regulating assembly and a water stopping assembly; the flow regulating assembly comprises a rotating actuating member, a receiving seat and a fixing seat; the receiving seat and the fixing seat are correspondingly providedwith a first water opening and a second water opening, and the two openings communicate each other to form a first water flow passage; one of the first water opening and the second water opening is provided with an eccentric characteristic cross section, and the other is provided with a linear characteristic cross section, so that the rate of change of the flow cross section of the first water flow passage is gradually increased along the rotational stroke; the receiving seat is further provided with a second water flow passage connecting to the first water flow passage through a third wateropening; and a sealing element of the water stopping assembly selectively seals the third flow opening, so that the first water flow passage and the second water flow passage are connected or blocked.The multi-function valve core achieves the linear increase of the flow change rate with the regulation stroke through the unique flow regulating assembly, low flow section is precisely adjusted, highflow section is responded rapidly, and the regulation is in a wide range.

Description

Technical field [0001] The invention relates to the technical field of sanitary products, in particular to a multifunctional valve core capable of regulating flow and stopping water. Background technique [0002] At present, showers and shower faucets used in the sanitary field generally use valve cores for waterway control. Such valve cores are usually divided into corresponding single-function valve cores according to the following types of user needs, such as switching water, flow adjustment, temperature adjustment, Waterway switching, etc. [0003] However, the use of multiple valve cores to design shower equipment, not only the structure of the waterway outside the valve core is complicated, the assembly is difficult, and the product volume is also large; and the existing composite multi-function valve cores with more than two types have corresponding defects , The user experience is poor, and it has greater limitations in use. [0004] Aiming at a composite multi-functional v...
