Description

TECHNICAL FIELD

[0001] The utility model relates to a temperature regulator technical field, concretely is a temperature regulator casing with anti -leakage design. BACKGROUND

[0002] The temperature regulator is an automatic temperature regulating device, mainly controls the flow path of cooling liquid. It contains temperature sensing components, opens or closes the flow of cooling liquid through the principle of thermal expansion and contraction, thereby adjusting the heat dissipation capacity of the cooling system, and ensuring that the engine works in the appropriate temperature range. The main structure of the wax type temperature regulator currently widely used in conventional use mainly consists of a barrel shell, paraffin wax, a rubber tube, a push rod and a barrel cover. Among them, the sealing between the barrel shell and the barrel cover is mainly formed by the rubber tube pressed into a closed state, the purpose is to prevent the internal paraffin wax from overflowing. On the other hand, after the assembly is completed, the barrel shell will also be internally spun into the upper edge of the barrel shell, so that the barrel cover and the rubber tube are completely clamped therein.

[0003] In summary, the existing temperature regulator main barrel structure has the following problems in use: although the sealing between the barrel shell and the barrel cover is formed by the rubber tube pressed into a closed state, the overall anti-leakage effect is good, but the upper end of the rubber tube will inevitably be physically and mechanically aged under the condition of long-term hard extrusion and frequent switching between high and low temperatures. Under the double factors, the rubber tube appears hardening and cracking, and then appears internal and external leakage, thereby affecting the sealing performance and normal use of the temperature regulator. Moreover, once the rubber tube is damaged and leaks, the entire temperature regulator or temperature regulator main barrel needs to be replaced, thereby causing material waste and increasing the comprehensive use cost of the temperature regulator. Therefore, the present application provides a temperature regulator casing with anti-leakage design and convenient disassembly and maintenance. SUMMARY
