Description

Technical Field

[0001] This utility model relates to the field of bathroom valve technology, and in particular to a water temperature and flow regulating valve structure. Background Technology

[0002] Most common shower bodies or concealed shower faucets have separate water temperature and flow rate regulating valves. These two valves and their operating mechanisms (such as knobs and handles) are usually installed separately in different locations. This separate installation of the two regulating valves requires a large space within the shower body or faucet body, resulting in a relatively large overall structure.

[0003] For concealed thermostatic shower faucets, an installation groove needs to be made in the wall. However, the overall size of the existing thermostatic shower faucet body is too large, and the corresponding installation groove size also needs to be large. An overly large installation groove can easily affect the pipe wiring and the installation of other equipment, so further improvement and optimization are needed. Utility Model Content

[0004] To address the aforementioned problems, the present invention aims to provide a water temperature and flow regulating valve structure. By coaxially mounting the water temperature and flow regulating operating mechanism, the valve body structure is made compact, the overall size is greatly reduced, and it is convenient for water temperature and flow regulation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A water temperature and flow regulating valve structure includes a valve body, a thermostatic regulating valve core, and a flow regulating valve core. The valve body has a cold water inlet, a hot water inlet, a thermostatic regulating valve seat, a flow regulating valve seat, and a warm water outlet. The thermostatic regulating valve core and the flow regulating valve core are respectively installed in the thermostatic regulating valve seat and the flow regulating valve seat. The thermostatic regulating valve seat has a coaxially arranged rotating gear ring sleeve. The teeth on the rotating gear ring sleeve mesh with a transmission gear on the flow regulating valve core. The rotating gear ring sleeve has two transmission rods connected to a rotating dial. A temperature regulating knob connected to the thermostatic regulating valve core is coaxially arranged outside the rotating dial.

[0006] Furthermore, the teeth are disposed on the outer cylindrical surface of the rotating toothed ring, and the teeth on the outer cylindrical surface are incomplete teeth.

[0007] Furthermore, the rotating gear ring sleeve is provided with a positioning step, the positioning step is connected to a limiting pressure plate, and the limiting pressure plate is fixed to the valve body.

[0008] Furthermore, the rotating dial is equipped with a rotating handle.

[0009] Furthermore, the rotating dial is provided with a handle hole for the rotating handle and a connection hole for the transmission rod.

[0010] Furthermore, an insulating ring is provided between the rotary dial and the temperature adjustment knob.

[0011] Furthermore, the valve body is located in a concealed housing, and the valve body extends to the outside of the concealed housing. A panel is provided on the outside of the concealed housing, and the rotary dial and temperature adjustment knob are located on the outside of the panel.

[0012] Furthermore, the warm water outlet includes two outlets, which are respectively located on both sides of the valve body.

[0013] This utility model has the following beneficial effects: 1. This utility model sets a coaxial rotating gear ring sleeve on the thermostatic regulating valve seat. The rotating gear ring sleeve adjusts the flow regulating valve core through the transmission gear. The rotating gear ring sleeve is connected to the rotating dial ring through the transmission rod. The temperature regulating knob and the rotating dial ring are set coaxially, which makes it easier to design a more compact valve body structure and greatly reduces the overall size of the valve body. The operating mechanisms of the two regulating valves are coaxially stacked, which also facilitates the use of water temperature and flow regulation.

[0014] 2. The outer cylindrical surface of the rotating gear ring sleeve of this utility model is provided with incomplete teeth for meshing transmission. The number of teeth is set according to the rotation angle of the flow regulating valve to avoid the rotation angle exceeding the adjustment range. Attached Figure Description
