Description

Micro-grid atomizing device capable of discharging mist upwards

Technical Field

The invention belongs to the technical field of medical appliances, and relates to a micro-grid atomizer, in particular to a micro-grid atomizer capable of generating mist upwards.

Background

Micro-grid atomization is an auxiliary technology for sucking medicaments, and the core component of the micro-grid atomization is an atomization sheet, and the atomization principle is as follows: the liquid contacts one side of the atomizing sheet, and countless tiny atomized particles are formed on the other side of the atomizing sheet through high-speed oscillation of the atomizing sheet, so that mist is generated.

The existing atomizing sheet is usually installed in the atomizer in a vertical, inclined or horizontal mode, but the existing atomizing sheet has the problems of limiting the use angle or causing inconvenient use.

1. The structure of vertical or inclined atomizing sheet is shown in figure 1, and comprises a cup cover 1', a nozzle 2', a medicine bin 3 'and an atomizing sheet 4', wherein the structure can increase the use angle by increasing the inclined surface angle of the bottom of the liquid bin, but when the liquid medicine is less, even if the inclined surface is arranged in the bin, the medicine cup is inclined backwards, and the liquid medicine still cannot contact the metal sheet and does not generate fog.

2. One configuration for a flat-laid aerosolized tablet is shown in fig. 2, where the drug reservoir 3' is positioned entirely above the aerosolized tablet 4', with the liquid contacting the aerosolized tablet 4', with the fog facing downward and the liquid contacting surface facing upward. But this structure has a use limitation: the common aerosol inhalation is that a user inhales mainly at the side of the machine, and the mist is discharged downwards to be guided to the side, so that a transfer pipe and a transfer mask are needed, and a space of 2-4 cm is reserved between the transfer volume and the distance from a mist outlet, so that the mist turns and cannot be condensed into water in a large amount, and the size of a product is limited.

3. Another structure of the horizontally-arranged atomizing sheet is shown in fig. 3, the atomizing sheet 4' is atomized upwards, the atomizing sheet 4' contacts liquid downwards, and a drainage rod 5' is needed to be added. Foam type drainage sticks are common in the market, but have the following two main problems: firstly, the liquid does not accord with biological compatibility, and secondly, the residual quantity of the liquid in the drainage rod is high.
