Description

Technical Field

[0001] The utility model relates to the field of bathing appliances, in particular to a regulating device with a novel thermostatic valve core component and a thermostatic bathing faucet. Background Art

[0002] Bathing is an indispensable part of daily life and is of great significance to improving the quality of life. As a key component of bathing equipment, the performance of the bath faucet directly affects the user's bathing experience. As an advanced bathing equipment, the thermostatic bath faucet realizes automatic adjustment of water temperature through the internal thermostatic device, thus providing users with a more comfortable and safe bathing environment.

[0003] The traditional thermostatic shower faucet mainly includes water delivery pipes, regulating devices and water outlet faucets. Among them, the regulating device is the core component of the thermostatic shower faucet, which includes the shell, control valve core assembly and thermostatic valve core assembly. The thermostatic valve core assembly is a key component to achieve constant water temperature, and its performance directly affects the overall performance of the thermostatic shower faucet.

[0004] The control principle of the thermostatic valve is mainly to automatically adjust the mixing ratio of hot and cold water to achieve the set water temperature by sensing the change in water temperature. When the water temperature at the outlet changes, the temperature sensing element inside the thermostatic valve core will sense this change and drive the valve core to move through the internal mechanical structure or electronic components, thereby adjusting the amount of hot and cold water inlet to stabilize the water temperature at the outlet within the set range.

[0005] However, the structure of the traditional thermostatic valve core assembly is relatively complex because it is composed of multiple components. In particular, multiple complex sealing structures and water pipes need to be assembled on the outside of the thermostatic rod. This complex structure not only increases the manufacturing cost, but also increases the difficulty of assembly. In addition, the matching accuracy between multiple components is required to be high. Once a problem occurs in a component, it may affect the performance of the entire thermostatic valve core assembly.

[0006] Therefore, how to simplify the structure of the thermostatic valve core assembly, reduce manufacturing costs and assembly difficulty, and at the same time ensure the stability and reliability of the constant temperature performance has become an urgent problem to be solved in the field of thermostatic shower faucets.

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 6As shown, a regulating device with a novel thermostatic valve core assembly includes a housing 1, a thermostatic valve core assembly 2 and a control valve core assembly 3. The thermostatic valve core assembly 2 and the control valve core assembly 3 are respectively arranged at the two ends of the housing 1 cavity, and a cold water inlet 4 and a hot water inlet 5 are arranged in the housing 1. This design makes the regulating device compact and convenient for controlling and regulating the cold and hot water flows. The thermostatic valve core assembly 2 includes a regulating valve 6, a displacement valve 7, a thermostatic rod 8 and an integrated water delivery device 9. The integrated water delivery device 9 includes an installation cavity, a cold water pipe 10, a hot water pipe 11 and a mixing water pipe 30. The regulating valve 6, the displacement valve 7 and the thermostatic rod 8 are sequentially installed in the installation cavity. This structure enables each component to cooperate closely to achieve precise water flow control. The displacement valve 7 moves back and forth under the action of the regulating valve 6 or the thermostatic rod 8. This design enables the displacement valve 7 to move flexibly according to water temperature changes or user adjustment requirements.

[0025] A cold water inlet 12 is formed between the displacement valve 7 and the regulating valve 6, and a hot water inlet 13 is formed between the displacement valve 7 and the thermostatic rod 8. A cold water pipe 10 and a hot water pipe 11 are arranged in the integrated water delivery device 9, and the cold water pipe 10 is aligned with the cold water inlet 12, and the hot water pipe 11 is aligned with the hot water inlet 13. An openable and closable cold water gap 14 is formed between the displacement valve 7 and the cold water pipe 10, and an openable and closable hot water gap 15 is formed between the displacement valve 7 and the hot water pipe 11. This design allows cold water and hot water to enter the cold water gap 14 and the hot water gap 15 through the cold water inlet 12 and the hot water inlet 13, respectively, thereby achieving mixing of cold and hot water.

[0026] The regulating valve 6 is rotated to control the moving position of the displacement valve 7, thereby controlling the ratio of cold and hot water entering from the cold water gap 14 or the hot water gap 15. When the user needs to adjust the water temperature, he only needs to rotate the regulating valve 6 to change the moving position of the displacement valve 7, thereby changing the ratio of cold and hot water entering from the cold water gap 14 or the hot water gap 15, and realizing accurate water temperature adjustment.

[0027] When the thermostatic rod 8 is heated and lengthened, it will push the displacement valve 7 to increase the cold water gap 14 and reduce the hot water gap 15; when the thermostatic rod 8 is cooled and shortened, it will push the displacement valve 7 to reduce the cold water gap 14 and increase the cold water gap 14. This design enables the thermostatic rod 8 to automatically adjust the mixing ratio of cold and hot water according to the change of water temperature to keep the water temperature constant.

[0028] The cold water pipe 10 and the hot water pipe 11 of the integrated water delivery device 9 are provided with a spacing protrusion 16, and a sealing ring 17 is provided between the spacing protrusion 16 and the displacement valve 7. This design realizes the separation of cold and hot water and avoids premature mixing. The spacing protrusion 16 and the sealing ring 17 work together to effectively prevent the mutual penetration and mixing of cold water and hot water in the pipe, ensuring the independence of cold and hot water before mixing.

[0029] The cold water pipe 10 is arranged below the cold water inlet 4, and the cold water gap 14 is arranged below the cold water pipe 10. The cold water pipe 10, the cold water inlet 4, and the cold water gap 14 are arranged in a vertical straight line. This design allows the cold water to be directly discharged into the cold water gap 14, reducing the bends and resistance of the water flow path, and improving the smoothness and efficiency of the water flow.

[0030] The hot water inlet 5 is arranged on the other side of the housing 1, and the hot water pipe 11 includes a transverse pipe 111. The inner wall of the end of the transverse pipe 111 and the displacement valve 7 form the hot water gap 15. This design allows hot water to flow smoothly into the hot water gap 15 and mix with cold water. At the same time, the design of the hot water pipe 11 meets the decoration requirements, which not only ensures the functionality of the shower system, but also meets the requirements of aesthetics and practicality.

[0031] A first mixing water pipe 301 is disposed transversely in the middle of the integrated water delivery device 9, and a second mixing water pipe 302 is disposed at the lower part of the integrated water delivery device 9. After the cold and hot water are mixed, they are simultaneously discharged into the first mixing water pipe 301 and the second mixing water pipe 302. This design realizes multi-purpose control after the cold and hot water are mixed. The user can choose which mixing pipe to obtain the mixed water flow according to the needs, so as to meet different shower needs.

[0032] There is a heat insulation gap 18 between the integrated water delivery device 9 and the inner wall of the housing 1, and a supporting ridge 19 is provided on the outer wall of the integrated water delivery device 9, and the top of the supporting ridge 19 abuts against the inner wall of the housing 1. This design prevents the integrated water delivery device 9 from being conducted to the outside, thus avoiding heat loss. The heat insulation gap 18 and the supporting ridge 19 work together to form an effective heat insulation layer, reducing the transfer and loss of heat and improving the energy efficiency of the shower system.

[0033] The thermostatic rod 8 is sleeved with a first spring 20, one end of which abuts against the integrated water delivery device 9, and the other end abuts against the raised portion 21 of the thermostatic rod 8. This design achieves close proximity of the regulating valve 6, the displacement valve 7, and the thermostatic rod 8. The elastic action of the first spring 20 maintains a certain pressure between the components, thereby achieving close fit and stable operation.

[0034] The regulating valve 6 includes a second spring 22, an adjusting knob 23 and a push block 24. One end of the thermostatic rod 8 passes through the cavity of the displacement valve 7 and is inserted into the groove of the push block 24. The position of the displacement valve 7 is controlled by adjusting the position of the push block 24. This design enables the regulating valve 6 to accurately control the position of the displacement valve 7, thereby achieving accurate adjustment of the mixing ratio of cold and hot water. The user only needs to rotate the adjusting knob 23 to change the position of the displacement valve 7 through the interaction between the second spring 22 and the push block 24, thereby achieving the purpose of adjusting the water temperature.

[0035] In summary, this regulating device with a new thermostatic valve core assembly 2 realizes constant control and efficient use of shower water temperature through its unique design and mechanism coordination. Cold water and hot water are effectively separated and mixed in the integrated water delivery device 9, and the constant and comfortable water temperature is ensured through the precise control of the regulating valve 6 and the thermostatic rod 8. At the same time, the device also has the advantages of compact structure, multi-purpose control, heat insulation and energy saving, providing users with a more convenient and comfortable shower experience.

This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
