The invention discloses a water purification unit, and a pressure relief control system and method used in filter element replacement of the water purification unit. The pressure relief control systemcomprises a filter replacement instruction receiving component, which is used for receiving a filter replacement instruction and sending the instruction; a prompting module; and a control module, which is separately connected with the filter replacement instruction receiving component and the prompting module, and used for enabling the filtering system of the water purifying unit to be in a closed state so as to relieve pressure in a pipeline when having received the filter replacement instruction and controlling the prompting module to send a prompt message that permits filter element replacement after preset time. When the water purifying unit needs filter element replacement, the system will send the prompt message that permits filter element replacement after pressure in the pipelineis relieved, thereby preventing the phenomenon of outward water spraying due to pressure in the pipeline.
Description
technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a pressure relief control system for water purification equipment when replacing a filter element, a water purification equipment, and a pressure relief control method for water purification equipment when replacing a filter element. Background technique [0002] At present, most water purification equipment can replace the filter element according to the usage of the filter element. However, when the filter element of the water purification equipment is removed, due to the pressure in the pipeline, the pipeline will spray water outwards, which will cause some troubles to the personnel who replace the filter element. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the first purpose of the present invention is to propose a pressure relief c...
