[0002] As one of the important components in the thermostatic valve core, the paraffin thermal element is mainly used to sense water temperature and thus generate driving action.

[0003] Currently, the paraffin-based thermistor in thermostatic valve cores has poor corrosion resistance and is prone to scale buildup due to the limitations of its material properties, which affects its sensing rate and driving capability. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a thermostatic valve core paraffin thermistor to solve these problems.

[0005] The objective of this invention can be achieved through the following technical solution: A thermostatic valve core paraffin thermal element, characterized in that the thermal element includes a shell made of titanium alloy, the shell of the thermal element has a temperature sensing cavity, and the temperature sensing cavity is filled with a paraffin mixture for sensing water temperature and generating a driving action, the shell of the thermal element has an elastic film provided on the upper part of the paraffin mixture, and the thermal element also includes a thermal element connecting seat pressed onto the shell, and the thermal element connecting seat is equipped with a water-proof protective sleeve, the thermal element connecting seat has an interconnected inner cavity, and a rubber plug and a push rod are fitted in the inner cavity.

[0006] In the above-mentioned thermostatic valve core paraffin thermal element, the paraffin mixture is composed of copper powder, paraffin and stabilizer mixed in a certain proportion.

[0007] In the above-mentioned thermostatic valve core paraffin thermal element, the bottom of the push rod is provided with a wear-resistant pad.

[0008] Compared with existing technologies, this thermostatic valve core paraffin thermal element has the advantages of corrosion resistance, scale resistance, good temperature sensing effect and long service life. Attached Figure Description

[0010] In the diagram, 1 is the outer shell; 2 is the temperature sensing cavity; 3 is the paraffin mixture; 4 is the elastic film; 5 is the thermistor connector; 6 is the waterproof sleeve; 7 is the inner cavity; 8 is the rubber stopper; 9 is the push rod; and 10 is the wear-resistant gasket. Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 As shown, this thermostatic valve core uses a paraffin-based thermistor. The thermistor includes a housing 1 made of titanium alloy, which possesses good toughness, corrosion resistance, high strength, non-magnetic properties, and is resistant to scale buildup. The housing 1 contains a temperature-sensing cavity 2 filled with a paraffin mixture 3 for sensing water temperature and generating a driving action. An elastic film 4 is located above the paraffin mixture 3 within the housing 1. The thermostatic valve core also includes a thermostatic element connector 5 press-fitted onto the housing 1, with a water-resistant sleeve 6 mounted on the connector 5. The connector 5 has an interconnected inner cavity 7, in which a rubber stopper 8 and a push rod 9 are fitted. When the paraffin mixture 3 is heated, its volume changes, causing the elastic film 4 to expand towards the inner cavity 7 of the connector 5, moving the push rod 9 and activating the thermostatic valve core.

[0013] Preferably, the paraffin mixture 3 is a mixture of copper powder, paraffin and stabilizer in a certain proportion.

[0014] To elaborate further, the bottom of the push rod 9 is equipped with a wear-resistant pad 10 to prevent direct contact with the rubber stopper 8.

[0015] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.

[0016] Although this document frequently uses terms such as outer shell 1, temperature sensing cavity 2, paraffin mixture 3, elastic film 4, thermal element connector 5, waterproof sheath 6, inner cavity 7, rubber plug 8, push rod 9, and wear-resistant gasket 10, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention.
