Description

Technical Field

[0001] This utility model relates to an evaporative humidifier, and more particularly to a mold structure for an evaporator plate of a pure humidifier. Background Technology

[0002] During dry seasons, people's skin may crack, necessitating increased air humidity to improve the comfort of their living environment. This is where humidifiers come in handy. Most humidifiers are ultrasonic humidifiers, which primarily use high-frequency ultrasonic vibrations to atomize water, which is then diffused into the air via a blower to humidify the air. While ultrasonic humidifiers are inexpensive and provide strong humidification, they are very sensitive to water quality and cannot be used with tap water. Regular cleaning is also necessary; otherwise, they may cause health problems.

[0003] Evaporative humidifiers, represented by pure humidifiers, achieve humidification by rapidly diffusing water vapor through natural evaporation and a fan. Their advantages include natural evaporation, health and antibacterial properties, and high humidification efficiency.

[0004] To achieve efficient evaporation, the pure humidifier uses an array of 38 precisely arranged evaporation plates. Each plate has a honeycomb or hexagonal micro-convex structure, forming a uniform, ultra-thin water film of over 2 square meters through the surface tension of water, maximizing the contact area between the water film and the air. The evaporation plate array is driven by gears, rotating slowly like a waterwheel to increase the frequency of water-air contact. This, combined with a cross-flow fan, increases the airflow velocity over the water film surface, further enhancing humidification efficiency.

[0005] Therefore, as the core component of a pure humidifier, the evaporator array requires precise control of spacing to achieve efficient evaporation. The evaporator also needs a large surface area and light weight. To ensure rotational stability and reduce vibration and noise, the evaporator also needs a large diameter, a small wall thickness, and uniform wall thickness with good flatness.

[0006] Existing manufacturing methods are unlikely to meet the above requirements.

[0007] In view of the above, this utility model is hereby proposed. Utility Model Content

[0040] The venting groove 4, which is connected to the evaporator plate adhesive position, is 5mm wide and 0.01mm deep, and 36 venting grooves are evenly distributed around the outer circle of the evaporator plate.

[0041] The 36 exhaust grooves 4 are surrounded by a circular air intake groove 5 with a depth of 0.3 mm and a width of 5 mm; around the circular air intake groove 5 are 4 air intake grooves 6 with a depth of 0.3 mm and a width of 5 mm that are connected to the outside of the mold cavity.

[0042] The mold adopts a two-plate mold structure with two cavities in one mold, and each cavity is equipped with a needle valve type hot runner injection structure.

[0043] The evaporator of the pure humidifier has an evaporator plate with a diameter of 190mm and a thickness of 0.8mm; the front and back of the evaporator plate are covered with hexagonal protrusions with a protrusion height of 0.1mm.

[0044] In summary, the evaporator plate mold for the pure humidifier in this embodiment features a two-cavity design.

[0045] To more clearly demonstrate the technical solution and effects provided by this utility model, the following detailed description of the embodiments of this utility model is provided with reference to specific examples.

[0046] Example 1

[0047] As shown in the figure:

[0048] Take a pure humidifier as an example:

[0049] like Figure 1a , Figure 1b As shown, the evaporator plate of the pure humidifier has a diameter of 190mm and a thickness of 0.8mm;

[0050] like Figure 1c As shown, the evaporator plate has hexagonal protrusions densely distributed on both sides, with a protrusion height of 0.1 mm.

[0051] To meet the various functional requirements of the evaporator for the evaporator in a pure humidifier, the evaporator mold needs to ensure that there are no defects such as deformation or missing glue during the molding process, that the surface micro-convex structure is clear, and that the surface roughness meets the requirements.

[0052] Taking the evaporator plate mold of a pure humidifier as an example, we will now introduce in detail the mold structure that meets various molding requirements:

[0053] 1. For example Figure 2 As shown, the mold adopts a two-plate mold structure with two cavities per mold, and each cavity is filled with a hot runner injection method using a needle valve.

[0054] 2. For example Figure 3 As shown, the front mold uses five rows of 8 mm diameter cooling water channels to control the front mold temperature;

[0055] 3. For example Figure 4 As shown, the rear mold uses four rows of 8 mm diameter cooling water channels to control the mold temperature.

[0056] 4. For example Figure 5 As shown, the mold ejects the product using 12 10mm diameter round ejector pins on the outer ring and 6 2mm diameter round ejector pins on the inner ring.

[0057] 5. For example Figure 6 , Figure 7 As shown, the mold's rear parting surface employs a two-stage venting structure. The venting grooves, connected to the evaporator plate's glue position, are 5mm wide and 0.01mm deep, distributed circumferentially around the outer edge of the evaporator plate, totaling 36 grooves. Surrounding these 36 venting grooves is a circular air-guiding groove, 0.3mm deep and 5mm wide. Around this circular air-guiding groove are four additional air-guiding grooves, each 0.3mm deep and 5mm wide. Gas venting from the cavity ultimately exits the mold through these four air-guiding grooves.

[0058] 6. The front and rear model cavity planes are densely packed as follows: Figure 1c The diagram shows a regular hexagonal micro-concave structure.

[0059] In summary, the evaporator plate mold for the pure humidifier features a two-cavity design, with injection via a two-point needle valve hot runner system. The product is ejected using 12 ejector pins (10mm diameter and 6 2mm diameter). The front and rear mold cores have densely packed hexagonal micro-concave structures on their cavities, and the front and rear cores are equipped with 5 and 4 cooling channels (8mm diameter) respectively. The rear mold parting surface has 36 venting grooves (0.01mm deep), and the gas is ultimately discharged from the cavity through venting channels. The resulting product has a large diameter, thin thickness, and light weight, with a clear and complete micro-convex structure. The product does not deform and has good flatness, meeting the high requirements of pure humidifiers for evaporator plates.
