Description

Pure humidifier evaporation piece mould structure Technical Field The utility model relates to an evaporative humidifier, in particular to a pure humidifier evaporation sheet die structure. Background In the season of air drying, the skin of people is cracked, the humidity of air is required to be increased to improve the comfort of living environment, and then a humidifier is required. The general humidifier is an ultrasonic humidifier, and is mainly characterized in that water is atomized through ultrasonic high-frequency vibration and then is diffused into the air through a blowing device, so that the aim of air humidification is fulfilled. Although the ultrasonic humidifier has low price and high humidification intensity, the ultrasonic humidifier has higher requirement on water quality, tap water cannot be added, regular cleaning is needed, and otherwise health problems can be caused. The evaporative humidifier represented by the pure humidifier achieves the aim of humidification by natural evaporation and rapid diffusion of water vapor by a pneumatic device, and has the advantages of natural evaporation, healthy bacteriostasis and high humidification efficiency. In order to achieve the aim of efficient evaporation, the pure humidifier adopts 38 evaporation sheets which are precisely arranged to form an array, meanwhile, the surface of a single evaporation sheet is designed into a honeycomb or hexagonal micro-convex structure, and a uniform ultrathin water film with the total surface tension of more than 2 square meters is formed through the surface tension of water, so that the contact area of the water film and air is increased to the greatest extent. The evaporation sheet array is driven by gear transmission and rotates slowly like a large water truck, so that the contact frequency of water and air is increased, and meanwhile, the through-flow fan is matched, so that the air flow velocity on the surface of a water film is increased, and the humidifying efficiency is increased. Therefore, the evaporation sheet is used as a core part of the pure humidifier, and in order to meet the purpose of efficient evaporation, the space between the evaporation sheet arrays needs to be precisely controlled, and the evaporation sheet needs to have a larger surface area and a lighter weight. In order to ensure the stability of rotation and reduce vibration and noise caused by rotation, the evaporation sheet also needs to ensure uniform wall thickness and good flatness while having a larger diameter and smaller wall thickness. The prior art manufacturing method is difficult to meet the above requirements. In view of this, the present utility model has been made. Disclosure of utility model The utility model aims to provide a pure humidifier evaporation sheet die structure so as to solve the technical problems in the prior art. The utility model aims at realizing the following technical scheme: The utility model relates to a pure humidifier evaporation sheet mould structure, which comprises a front mould and a rear mould; The mold core of the front mold and the mold core of the rear mold are respectively provided with a plurality of rows of cooling water channels 1; the rear die is provided with an outer ring round ejector rod 2 and an inner ring round ejector rod 3; the rear die parting surface is provided with a two-stage exhaust groove structure; and the cavity plane of the cavity of the front die and the cavity plane of the cavity of the rear die are densely distributed with regular hexagonal micro-concave structures. Compared with the prior art, the pure humidifier evaporation sheet die provided by the utility model has the advantages that the formed product is large in diameter, thin in thickness, light in weight, clear and complete in micro-convex structure, free of deformation and good in flatness, and meets the higher requirements of the pure humidifier on the evaporation sheet.
