After long-term use, the filter plate will be blocked due to the interception of a large amount of impurities. At this time, it needs to be cleaned. However, due to the bolt fixation, professional tools are needed to loosen the multiple bolts one by one during cleaning, which is tedious and time-consuming. Therefore, a temperature control valve structure is proposed to solve the above problems. UTILITY MODEL CONTENTS
