Description

Tap control valve

Technical Field

The utility model relates to the technical field of bathroom equipment, in particular to a faucet control valve.

Background

The conventional tap temperature control switch that uses in the market is the hand wheel of manual formula (that is the case control), needs the hand wheel of manual regulation in order to control the aperture of case when using to control tap's play water temperature, but manual regulation case hardly accurate control temperature, causes play water temperature unstable, especially child has the hidden danger of scald in the use. In addition, the on-off of the tap is controlled by hand contact, bacteria are easy to remain on the contact part, secondary pollution is caused, and the possibility of disease transmission exists. With the progress of society, traditional tap products have failed to meet the requirements of vast consumers. Some faucets are disclosed in the prior art, the faucet is opened and closed by induction, so that the faucet is opened and closed in a non-contact way, and the faucet is safer to use.

The faucet comprises a faucet main body and a control assembly, wherein the control assembly comprises a valve seat, an executing piece and a controller; the valve seat is provided with a first water inlet flow passage, a second water inlet flow passage and a second water outlet flow passage, the first water outlet flow passage and the second water inlet flow passage are communicated, and the second water inlet flow passage is connected with the tap main body; the valve seat is internally provided with a first valve core and a second valve core, the first valve core can adjust the communication area of the first water inlet flow channel and the second water outlet flow channel, the second valve core can adjust the communication area of the second water inlet flow channel and the second water outlet flow channel, the executing piece is connected with the first valve core and the second valve core and can control the opening of the first valve core and the second valve core, the executing piece is electrically connected with the controller, and the controller can control the executing piece to operate and close. After the water inlet temperature changes, the water tap can maintain the stability of the water outlet temperature to a certain extent. The defects are that: because the cold water valve core and the hot water valve core are controlled by separate motors, each motor is responsible for adjusting the water quantity and the temperature, so that the water yield and the water outlet temperature after cold water and hot water are mixed are difficult to coordinate, and the control is not very good.

Therefore, some improved control valves have appeared in the market later, such as "control box for faucet" disclosed in chinese patent application No. 202223016264.5 (issued to CN 218598877U), which includes a box body, a valve seat built in the box body, and a first water inlet channel, a second water inlet channel and a water outlet channel on the valve seat. According to the utility model, the first water inlet channel and the second water inlet channel are respectively arranged on the valve seat, the respective water outlet quantity is controlled through the first valve core arranged on the first water inlet channel and the second valve core arranged on the second water inlet channel, the first valve core and the second valve core are synchronously controlled to run by the first motor, and the mixing valve core arranged on the water outlet channel is driven by the second motor, so that the proportion of the mixed water outlet quantity is controlled, and the water temperature of the water outlet channel is controlled. The water outlet quantity and the water outlet temperature are controlled by the independent operation of the first motor and the second motor, and the control of the first motor and the second motor is easy to be coordinated, so that the water outlet quantity of the first water inlet channel and the water outlet quantity of the second water inlet channel are always kept synchronous, and unstable water outlet temperature caused by the fact that cold water and hot water are in different proportions is avoided.

However, because the control valve adopts a double-operation mode of double motors and double valve cores, the control valve has more internal parts, so that the volume is relatively large, the whole structure is not compact, the problem of high cost exists, and meanwhile, the prior assembly and the later maintenance and disassembly of the control valve are difficult to a certain extent. In certain specific occasions, the control valve is only required to realize the regulation function of the water outlet temperature, the control of the water outlet amount is not required, and the regulation and control of the mixed water outlet amount are realized by simply switching and controlling an external water tap, so that the control valve with double motors and double valve cores is not suitable from the aspects of cost reduction and convenient use.

Therefore, how to provide a control valve which has compact and reasonable structure, small volume and low cost, can be more convenient for early-stage manufacturing, assembly and later-stage maintenance and use, has flexible temperature adjustment and can meet the water outlet requirements of different temperatures is a problem which needs to be solved by the technicians in the field.
