通常情况下,制作凸台141的材质为塑胶;当凸台141换气口的截面的当量直径小于0.3mm时,会增加使用塑胶制成凸台141的难度。若凸台141的材质选用硅胶,根据制作工艺,凸台141的换气口的截面的当量直径可以小于0.3mm,但硅胶的一致性相对于塑胶较差,且硅胶制成凸台141相对于塑胶制成凸台141对流体具有更大的阻力,无法保证换气效果更好。Usually, the material for making the boss 141 is plastic; when the equivalent diameter of the cross-section of the ventilation port of the boss 141 is less than 0.3 mm, it will be more difficult to use plastic to make the boss 141 . If the material of the boss 141 is silica gel, according to the manufacturing process, the equivalent diameter of the section of the ventilation port of the boss 141 can be less than 0.3mm, but the consistency of the silica gel is relatively poor compared to plastic, and the boss 141 made of silica gel is relatively The boss 141 made of plastic has greater resistance to the fluid, which cannot guarantee a better ventilation effect.
当凸台141的换气口的截面的当量直径大于0.7mm时,沿程阻力变小,易造成漏液;且当量直径大于0.7mm时,需要抽吸两口以上才会换气一次(理想状态下为每抽吸两口换一次气),可以会影响下液速度,进而造成干烧等问题。研究发现,分别在抽吸一口、抽吸两口、抽吸三口换一次气的凸台141的换气口的截面的当量直径如表1所示。When the equivalent diameter of the cross-section of the air exchange port of the boss 141 is greater than 0.7mm, the resistance along the way becomes smaller, which is easy to cause liquid leakage; The next is to change the air every two puffs), which may affect the speed of the liquid, which will cause problems such as dry burning. The study found that the equivalent diameters of the cross-sections of the air exchange ports of the boss 141 for one air exchange at one suction port, two suction ports, and three suction ports are shown in Table 1.

现有的换气通道通常为微槽或微孔,微槽或微孔与储液腔的底壁或侧壁的上的通孔直接相连,即,换气通道的换气口(储液腔的底壁或侧壁上的通孔的端口)与储液腔的内表面平齐,气泡容易沿着储液腔的底壁或侧壁生长,使得气泡难脱离,且气泡脱离大小不可控,易出现多个气泡融合,进而易挡住进液口,造成换气不稳定,导致供液不足,产生抽吸焦味。而本申请实施例中通过在储液腔14的内壁面上设置凸台141,且凸台141上设置有换气口,该换气口与换气通道18连通,即换气通道18的换气口高于储液腔14的内壁面,以利于破坏从换气通道18进入储液腔14中气泡的表面张力,利于气泡的脱离,使换气更流畅,降低气泡卡住进液口的风险,改善抽吸过程中由于换气不好,从而下液不流畅产生焦味的问题。Existing ventilation channels are usually microgrooves or micropores, and the microgrooves or micropores are directly connected to the through holes on the bottom wall or the side wall of the liquid storage chamber, that is, the ventilation port of the ventilation channel (liquid storage chamber The bottom wall or the port of the through hole on the side wall) is flush with the inner surface of the liquid storage chamber, and the bubbles are easy to grow along the bottom wall or side wall of the liquid storage chamber, making it difficult for the bubbles to detach, and the size of the detachment of the bubbles is uncontrollable. It is easy for multiple bubbles to fuse, and then it is easy to block the liquid inlet, resulting in unstable ventilation, insufficient liquid supply, and a burnt smell. However, in the embodiment of the present application, a boss 141 is set on the inner wall surface of the liquid storage chamber 14, and a ventilating port is arranged on the boss 141, and the ventilating port communicates with the ventilating passage 18, that is, the ventilating passage 18 of the ventilating passage 18 communicates with the ventilating passage. The air port is higher than the inner wall surface of the liquid storage chamber 14, so as to destroy the surface tension of the air bubbles entering the liquid storage chamber 14 from the air exchange channel 18, facilitate the detachment of the air bubbles, make the air exchange more smooth, and reduce the possibility of air bubbles getting stuck in the liquid inlet. Risk, improve the problem of burnt smell due to poor ventilation during the suction process.

The distance between the boss 141 and the sidewall of the liquid storage cavity 14 is greater than 1mm. By setting the boss 141 to be spaced apart from the side wall of the liquid storage chamber 14, usually the radius of the air bubble is 1 mm, and the distance between the boss 141 and the side wall of the liquid storage chamber 14 is greater than 1 mm, so that the air bubbles can be prevented from moving along the side wall of the storage chamber 14. The growth of the side wall of the liquid chamber 14 can reduce the diameter of the detachment of the bubbles, so that the detachment of the bubbles can be faster and smaller, and the burning smell of the suction can be avoided as much as possible. By protruding the top surface of the boss 141 from the bottom wall of the liquid storage chamber 14, the bubbles can be prevented from growing along the bottom wall of the liquid storage chamber 14, the diameter of the bubbles can be reduced, and the bubbles can be separated faster and smaller .
