Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
As shown in figures 1-6, the thermostatic valve core with stable temperature regulation comprises a shell 1, wherein the shell 1 is hollow. The side surface of the shell 1 is provided with a cold water inlet 2 and a hot water inlet 3, and the bottom of the shell 1 is provided with a mixed water outlet channel. The shell 1 is internally provided with a temperature adjusting component 5, a temperature adjusting piston 7, a temperature bulb 6 and a return spring 8. The temperature adjusting piston 7 is arranged inside the shell 1 in a sliding mode, and the thermal bulb 6 is connected with the temperature adjusting piston 7 through threads. The temperature adjusting component 5 is used for setting the outlet water temperature. The temperature bulb 6 detects the temperature of the mixed water and pushes the temperature adjusting piston 7 to slide up and down together with the return spring 8, so that the mixing proportion of cold water and hot water is changed to adjust, and the outlet water temperature of the mixed water is kept consistent with the set outlet water temperature. When the temperature-adjusting device works, cold water enters the shell 1 from the cold water inlet 2 at the upper end of the temperature-adjusting slide block 16, then enters the lower part of the temperature-adjusting piston 7 through the communicating hole 9 in the middle of the temperature-adjusting piston 7, hot water enters the shell 1 from the lower end of the temperature-adjusting piston 7, and is mixed with the cold water flowing down from the communicating hole 9 to form mixed water, and finally the mixed water flows out of the shell 1 from the mixed water outlet channel at the lower end of the shell 1.
The lower part of the temperature adjusting piston 7 is an annular part 10, a backflow ring 11 is arranged on the lower side of the temperature adjusting piston 7, the backflow ring 11 is sleeved at the lower end of the thermal bulb 6, and the upper end of the return spring 8 is propped against the bottom of the backflow ring 11, so that the backflow ring 11 can move up and down along with the temperature adjusting piston 7. The upper end of the backflow ring 11 is positioned at the inner side of the annular part 10, and the middle part of the backflow ring 11 is provided with a flow passing hole 12 for mixed water to flow through. When hot water flows into the valve core, the upper end of the return ring 11 blocks the hot water, so that the hot water flows to the upper part of the return ring 11 along the surface of the return ring 11 and then is mixed with cold water flowing down from the upper end of the temperature adjusting piston 7 through the communication hole 9. Because the flowing directions of the cold water and the hot water are opposite, the cold water and the hot water impact each other, the cold water and the hot water can be uniformly mixed in the area above the backflow ring 11, and then flow to the lower part of the backflow ring 11 from the overflowing hole 12 on the backflow ring 11 to be contacted with the temperature sensing part of the bulb 6 below the backflow ring 11. When the valve core without the backflow ring 11 is used, cold water at the upper end of the temperature adjusting piston 7 flows downwards from the communicating hole 9 in the middle of the temperature adjusting piston 7, water flow is concentrated, hot water at the lower end of the temperature adjusting piston 7 flows into the periphery of the lower end of the temperature adjusting piston 7 and is located on the outer side of the cold water flow, flow speed is low, mixing between the hot water and the cold water is not uniform, and a temperature sensing area of the thermal bulb 6 is more in contact with the cold water, so that inaccurate temperature sensing is caused. After the backflow ring 11 is arranged, cold and hot water can be mixed uniformly above the backflow ring 11, and then the cold and hot water is in contact with the temperature-sensitive area of the thermal bulb 6, so that the temperature-sensitive area of the thermal bulb 6 can truly reflect the temperature of mixed water, and the temperature regulation of the thermostatic valve core can be more stable and accurate.
The outer side surface of the upper end of the backflow ring 11 is provided with an inclined surface 13, so that the outer side surface of the upper end of the backflow ring 11 is conical. The inclined surface 13 is arranged so that hot water can flow along the inclined surface 13 to the upper part of the temperature adjusting piston 7 when contacting with the upper end of the return ring 11, and can be cut into the cold water flow more easily, and can be mixed with the cold water more quickly and better.
The 11 lateral surfaces of backward flow circle and 1 inner wall sliding fit of casing, the clearance is less between the two for water after the preliminary mixing mainly flows into backward flow circle 11 below from the discharge orifice 12 in the middle part of backward flow circle 11, increases the distance that rivers flow, makes cold water and hot water can mix more evenly at the in-process that flows.
The backflow ring 11 is sleeved on the temperature sensing part of the thermal bulb 6, the middle part of the backflow ring 11 is abutted against the protruding part of the thermal bulb 6, and the lower end of the backflow ring 11 is abutted against the upper end of the reset spring 8, so that after installation, the backflow ring 11 can slide up and down along with the temperature adjusting piston 7, and the upper end of the backflow ring 11 is always positioned inside the annular part 10 on the lower side of the temperature adjusting piston 7.
The filter screen 14 is installed in the cold water inlet 2 and the 3 outsides of hot water inlet, and filter screen 14 can block the particulate matter of aquatic, avoids inside great particulate matter enters into the case.
The upper part of the tempering piston 7 is also provided with an annular part 10, and the annular part 10 inclines outwards from the middle part of the tempering piston 7. The annular part 10 thus makes the contact area between the side of the tempering piston 7 and the inner wall of the housing 1 smaller, and when the two slide relatively, the friction force generated is smaller and the sliding is more flexible.
The reset spring 8 is a conical spring, the larger lower end of the conical spring is abutted against the bottom of the inner cavity of the valve core, and the upper end of the reset spring 8 is abutted against the bottom of the return ring 11. By using the conical spring, the stability of the reset spring 8 is better when the reset spring is pressed, the whole reset spring is not easy to incline, and the work is more stable.
The temperature adjusting assembly 5 comprises a temperature adjusting knob 15 and a temperature adjusting slider 16, the temperature adjusting knob 15 is rotatably arranged at the upper end of the inner cavity of the shell 1, and the temperature adjusting knob 15 can rotate in the shell 1. The temperature adjusting slider 16 is arranged below the temperature adjusting knob 15 and is in transmission connection with the temperature adjusting knob through threads. The side surface of the temperature regulating slider 16 is circumferentially engaged with the inner wall of the shell 1, so that the temperature regulating slider 16 can only slide up and down in the shell 1 and cannot rotate circumferentially relative to the shell 1. When the temperature adjusting knob 15 rotates, the temperature adjusting slider 16 slides up and down under the driving of the screw thread, thereby setting the outlet water temperature. The temperature adjusting slide block 16 is internally provided with a rear buffer spring 17 and a spring seat which is abutted against the upper end of the thermal bulb 6.
The above description is intended to be illustrative of the present invention and not to limit the scope of the utility model, which is defined by the claims appended hereto.
