Description

Single-handle double-inlet and double-outlet temperature regulating valve core

Technical Field

The utility model belongs to shower system field relates to a single handle advances two times case that adjusts temperature.

Background

The prior art shower system, as shown in fig. 14, basically comprises a shower tap (1 '), cold and hot water inlet pipes (2 ', 3 ') communicating with the shower tap, and a water outlet pipe (4 ') communicating with the shower tap, along which water outlet pipe (4 ') warm water flows from a hand shower (5 ') or a top shower (6 '). The main control unit in the shower faucet is a mixing valve core, cold water and hot water respectively enter the mixing valve core and are mixed into warm water to flow out, the mixing valve core plays a role in mixing cold water and hot water and simultaneously controlling the flow limitation of a water path switch, if the Chinese patent discloses a novel shower faucet, the application number is CN201520090732.4, and the mixing valve core in the novel shower faucet is just as the structure.

However, the existing shower system with mixing and then water discharging has the defect that for the convenience of cleaning, the shower faucet (1 ') is usually arranged at the height of the waist of a human body, and the hanging point or the top shower head (6') of the hand-held shower head (5 ') is arranged above the head of the human body, so that the height difference needs a longer water outlet pipeline (4') for transitional warm water. Therefore, when a person feels that the water temperature is not proper during bathing, the water temperature is adjusted by rotating the adjusting handle of the shower faucet (1 '), and the water outlet pipeline (4 ') is long, so that when the water temperature is adjusted each time, the warm water in the water outlet pipeline (4 ') is required to flow out, the adjusted warm water can flow out, and the change of the water temperature sprayed by the shower head can be felt until the water temperature is adjusted to be suitable for personal bathing.

In the actual bathing process, the water temperature is often adjusted to the personal suitable water temperature by adjusting for a plurality of times, and the water temperature adjusting process is insensitive, and is troublesome, time-consuming and water-consuming.

Based on this, the inventor proposes a new shower system, namely, a water mixing area is arranged at the rear, the water mixing area is closer to the water outlet of the hand-held shower head (5 ') and the top shower head (6'), and cold water and hot water respectively enter and exit from the shower faucet before the water mixing area.

In the prior art, a cold and hot water double-switch valve core exists, such as a ceramic valve disc assembly with application number 201120579550.5 and a cold and hot water double-switch valve core with the same, the ceramic valve disc assembly comprises a stator (1) and a rotor (2), the rotor (2) can rotate on the stator (1) along the axis thereof, the stator (1) is provided with four through holes (A, B, C, D) which are inlet and outlet of cold and hot water, the rotor (2) is provided with two cavities (E, F), when the rotor (2) rotates on the stator (1) along the axis thereof, each cavity on the rotor (2) can simultaneously communicate or separate two through holes on the stator (1) which correspond to the stator and are located on the same ring belt, so as to realize double-switch and double-throttle of cold and hot water. According to the ceramic valve plate assembly and the corresponding valve core, the cold water and the hot water are used for regulating the water quantity in the same proportion, so that the effects of opening, closing and regulating the flow are realized simultaneously, and the ceramic valve plate assembly and the corresponding valve core have no temperature regulation function. The switch valve core is often matched with a thermostatic valve core (the thermostatic valve core is a device which automatically adjusts the mixing proportion of cold water and hot water and enables the temperature of mixed water to be automatically kept at a set temperature) to control the temperature of the mixed water. Therefore, the structure of the faucet is complex, and the effects of on-off control and water quantity and temperature regulation can be achieved only by installing the switch valve core and the thermostatic valve core at the same time and controlling by the double handles. Therefore, the living cost is increased invisibly, and the operation is inconvenient.

So, current case can not satisfy novel shower system's the demand that adjusts the temperature, needs to treat to provide a new case that adjusts the temperature in order to adapt to novel shower system.

Disclosure of Invention

Aiming at the defects of slow temperature adjustment of outlet water and time and water consumption in the existing shower system, the existing water mixing valve core is difficult to meet the requirements of a new shower system, and the invention particularly provides the temperature adjusting valve core which has a single handle and can realize the double-inlet and double-outlet switch of cold water and hot water.

In the process of clockwise rotation of the handle 2, the coverage area of the cold water circulation groove 61 and the cold water outlet hole 73 of the stator is gradually reduced, namely the cold water flow is gradually reduced, and the water outlet proportion of cold water and hot water is in a hot-large-cold-small state.
