[0003] The existing technology has the following problems: the most important performance of the current constant temperature and humidity chamber is to achieve the heat preservation function, that is, to ensure that the humidity and temperature in the constant temperature and humidity chamber are maintained within a certain range. In actual use, when the temperature in the constant temperature and humidity chamber is too high, it is necessary to ensure that the internal temperature can be quickly reduced. When the temperature in the constant temperature and humidity chamber is too low, it is necessary to ensure that the internal temperature can be quickly increased.

[0038] The working principle of the present invention is as follows: the inner wall of the constant temperature and humidity chamber assembly 100 of the present invention is provided with a serpentine water pipe for temperature control, and at the same time, the inner wall of the constant temperature and humidity chamber assembly 100 is provided with a heating structure for heating and heating. The present invention mainly improves and designs the temperature control structure inside the constant temperature and humidity chamber. The reaction piston type hot and cold water regulating assembly 200 of the present invention forms a self-regulating plug structure for mixing hot and cold water in different proportions in the constant temperature and humidity chamber assembly 100. Through the structure of the reaction piston type hot and cold water regulating assembly 200, the constant temperature and humidity chamber assembly 100 is self-regulated for heating, heat preservation and cooling. At the same time, the constant temperature and humidity chamber heat sensing assembly 300 forms a piston in the constant temperature and humidity chamber assembly 100 that triggers the self-regulation of the reaction piston type hot and cold water regulating assembly 200. Driving structure, the constant temperature and humidity chamber thermal sensing component 300 serves as a trigger structure for temperature control self-regulation. At the same time, the high-pressure water tank component 400 forms a water storage tank structure in the constant temperature and humidity chamber component 100 to supply rated pressure to the reaction piston type hot and cold water regulating component 200. Through the action of the high-pressure water tank component 400, it is ensured that the reaction piston type hot and cold water regulating component 200 is provided with safe rated high-pressure water. This function is to avoid the influence of excessive high-pressure water on the self-regulation of the reaction piston type hot and cold water regulating component 200. Because if too high pressure water is sent to the reaction piston type hot and cold water regulating component 200, it will affect the sealing and unblocking effect of the internal hot and cold water, thereby affecting the temperature control effect in the constant temperature and humidity chamber component 100. Its specific working principle As shown below, in the initial state, the cold water sealing head 204 seals the cold water inlet cover 207, and the hot water sealing head 216 and the hot water inlet cover 215 are in an unsealed structure. At this time, the hot water in the hot water storage tank 406 enters the serpentine wall tube inside the constant temperature and humidity chamber 101 through the temperature control water outlet pipe 211 on the reaction piston type hot and cold water regulating component 200. At this time, an auxiliary heating mode is formed inside the constant temperature and humidity chamber 101. When the temperature inside the constant temperature and humidity chamber 101 is too high, the paraffin in the paraffin chamber 302 will melt and expand. At this time, the primary piston 303 will press the gas in the piston gas chamber 306 to enter the central cavity tube 201. At this time, the filling of gas will cause the pressure in the central cavity tube 201 to increase. At this time, the excessive pressure will press the secondary piston 2 05 forms a thrust, because the secondary piston 205 is fixed, the central cavity tube 201 slides relative to the secondary piston 205 at that time, and due to the effect of the reaction force, the central cavity tube 201 drives the cold water sealing head 204 to release the blockage of the cold water inlet cover 207, and the central cavity tube 201 drives the hot water sealing head 216 to block the hot water inlet cover 215. At this time, a cooling mode in which only cold water but no hot water is introduced is formed in the constant temperature and humidity chamber assembly 100. At the same time, when the temperature drops to a certain temperature, that is, the temperature becomes low, but the temperature in the constant temperature and humidity chamber 101 reaches the rated temperature, that is, the intermediate temperature, the paraffin in the paraffin chamber 302 will partially recover to its original state, and the cold water sealing head 204 semi-blocks the cold water inlet cover 207.The hot water sealing head 216 and the hot water inlet cover 215 are in a semi-sealed structure, and the constant temperature and humidity chamber 101 is in a heat preservation mode. The reaction piston type hot and cold water regulating assembly 200 and the constant temperature and humidity chamber thermal sensing assembly 300 are important core components of the present invention. The constant temperature and humidity chamber thermal sensing assembly 300 triggers temperature sensing, allowing the reaction piston type hot and cold water regulating assembly 200 to switch automatically between heating mode, heat preservation mode, and cooling mode within the constant temperature and humidity chamber assembly 100.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
