In addition to the pump body, there are other factors that may also cause the temperature to fail to reach the specified temperature. At this time, the entire system needs to be maintained, which takes time. During this period, the comfort level will be reduced, affecting the normal use of the user. Therefore, a device is urgently needed to solve the above problems. Utility Model Content
