Embodiment Construction

[0022] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", horizontal" etc. are based on th...

Abstract

The invention discloses a proportional aerosol valve for inhalation administration. The valve comprises a valve body, a lower side of the valve body is connected with a base, a base liquid inlet is arranged on the base, and a sealing cup is connected to the valve body; the quantitative aerosol valve further comprises an aspiration component, the aspiration component comprises an upper valve rod, and a limiting bulge is arranged on an outer wall of the upper valve rod; an upper valve rod liquid inlet groove is formed in the upper valve rod and located above the limiting bulge, and a first sealing ring is arranged above a proportional valve chamber; the upper valve rod liquid inlet groove is formed in the upper valve rod and located on the side wall below the limiting bulge, the lower end ofthe upper valve rod is connected with a lower valve rod, a spring is arranged between the lower valve rod and the base, and a second sealing ring is arranged on the outer side of the upper valve rodand located between the valve body and the base. The aspiration component comprises the upper valve rod and the lower valve rod arranged at the lower end of the upper valve rod, the upper valve rod and the lower valve rod can be assembled and disassembled, the spring is located at the lower end of the lower valve rod and arranged outside the proportional valve chamber, the storage amount of the proportional valve chamber is not occupied, each pressing can be guaranteed to reach the standard injection amount.

Description

【Technical field】 [0001] The invention relates to a valve for inhaling and administering a quantitative aerosol. 【Background technique】 [0002] Quantitative valve is a special valve that can precisely control the flow rate released by the fluid source each time. Quantitative valves are widely used in daily chemical and pharmaceutical industries. For example, common aerosols and other products are equipped with quantitative valves. The structure of the existing quantitative valve is relatively complex, and the assembly is inconvenient, and the sealing effect between the various parts is not very ideal, and the situation of air leakage often occurs; moreover, the springs are arranged inside the quantitative valve chamber, occupying the The storage capacity of the quantitative valve chamber will inevitably lead to deviations in the accuracy of the aerosol spray volume, which cannot meet the requirements of production and use. [0003] The present invention just produces base...
