Description

A kind of vapour-pressure type medical liquid atomizing instrument

Technical field

This utility model relates to a kind of vapour-pressure type medical liquid atomizing instrument, especially for the medical liquid atomizing instrument of treatment respiratory system disease.

Technical background

The medical liquid atomizing instrument that is used for the treatment of respiratory system disease at present is except the ultrasound wave type, also has compressed air type, it is to utilize small air pump that air compression formation high velocity air is impacted by little spray orifice to swing the medicinal liquid of makeup in little medicine glass, make it sputter and form fine vaporific microgranule ejection and inhale news, thereby reach the purpose of treatment or prevention for the patient.Mostly existing vapour-pressure type atomizing instrument is to adopt electromagnetic piston formula and motor with cup rotor formula (eccentric drives bent axle makes piston do straight reciprocating motion) to come compressed-air actuated.This dual mode all exists vibration big, and the bad patient of shortcomings such as noise height, particularly heart is difficult to stand the mechanicalness noise more than 50 decibels and makes people's discomfort that has the fidgets, thereby has influenced curative effect.

This utility model content

The purpose of this utility model is at above deficiency, and a kind of medical liquid atomizing instrument that adopts two air chamber structures of barrier film and low noise is provided.

The purpose of this utility model is achieved in that and comprises loam cake, shower nozzle, escape pipe, air inlet, housing and be installed in intravital two pairs of symmetric inside and outside air chambers of shell and motor, it is characterized in that shell respectively has a pair of symmetric inside and outside air chamber about intravital, outer air chamber and interior air chamber are tightly connected, be provided with leather cup and static diaphragm between the inside and outside air chamber, bar magnet is connected with interior air chamber, the exogenous QI outside is provided with escape pipe, housing is installed in the loam cake, base and air chamber medicated cushion, the gas storage sealing ring is formed air storage chamber, the exogenous QI outside is connected with the escape pipe of air storage chamber, base is provided with venthole, and venthole is connected with shower nozzle through a conduit.

The utlity model has following advantage: 1, energy-saving and low-noise and continuous operation for a long time; 2, stable, antidetonation and rapid heat dissipation; 3, sprinkler design novelty;

Description of drawings

Fig. 1 is a STRUCTURE DECOMPOSITION sketch map of the present utility model;

Fig. 2 is an outline drawing of the present utility model;

1 loam cake, 2 shower nozzles, 3 escape pipes, 4 air inlets, 5 housings, 6 interior air chambers, 7 outer air chambers, 8 motors, 9 bases, 10 housing seal circles, 11 bar magnets, 12 static diaphragms, 13 air storage chambers, 14 leather cups lid, 15 leather cups, 16 sealing gaskets, 17 air chamber medicated cushions, 18 gas storage sealing rings, 19 ventholes, 20 conventional nozzle, 21 animal formula nozzles, 22 conduits.

The specific embodiment

As shown in Figure 1, this utility model comprises loam cake 1, shower nozzle 2, escape pipe 3, air inlet 4, housing 5 and is installed in symmetric inside and outside air chamber (6,7) of two couples and motor 8 in the housing 5.The air inlet 4 that is installed in loam cake 1 is provided with the air inlet filter pulp, the below of loam cake 8 is provided with housing seal circle 10, when motor 8 work, in air is sucked into air drain in the housing 5 from air inlet 4, two pairs of symmetric inside and outside air chambers (6 about housing 5,7) produce air pressure by the vibration back and forth between two bar magnets 11, static diaphragm 12 cooperates the work of bar magnet 11, vibrating the air pressure that is produced back and forth is pressed onto the escape pipe 3 of air from outer air chamber 7 air storage chamber 13 that is formed by base 9 and air chamber medicated cushion 17, outer air chamber 7 is by leather cup lid 14, leather cup 15 joins with interior air chamber 6, like this at two pairs of symmetric inside and outside air chambers (6, just reduce noise when 7) vibrating back and forth.Housing 5 is installed in the loam cake 1, and sealing gasket 16 places the below of housing 5, and air chamber medicated cushion 17, gas storage sealing ring 18 place respectively and form air storage chamber 13 between sealing gasket 16 and the base 9.Escape pipe 3 joins by air storage chamber 13 venthole 19 and conduit 22 on base 9, and the other end of conduit 22 joins with the shower nozzle 2 that medicinal liquid is housed, and just medicinal liquid is become the vaporific news of inhaling by air pressure, thereby reaches the purpose of treatment.

As shown in Figure 2, outside the mouth that shower nozzle 2 of the present utility model can be conventional, the nose cup nozzle 20, can also be set as the nozzle 21 of forms such as replaceable cartoon style and animal.
