The invention discloses a water purification device and its pressure relief control system and method when replacing a filter element, wherein the pressure relief control system includes: a filter element replacement instruction receiving component, the filter element replacement instruction receiving assembly is used to receive the filter element replacement instruction, and perform Sending; Prompt module; Control module, the control module is respectively connected with the filter element replacement instruction receiving component and the prompt module, and the control module controls the filter system of the water purification equipment to be in a closed state when receiving the filter element replacement instruction to relieve the pressure of the pipeline, and After the preset time, the control prompt module sends out a prompt message allowing the replacement of the filter element. When the water purification equipment needs to replace the filter element, the system will send out a prompt message to allow the replacement of the filter element after the pressure in the pipeline is released, thereby preventing the occurrence of water spraying due to the 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...
