Abstract
The invention relates to a medical vaporizer. The medical vaporizer comprises an upper cover and a lower cover, wherein a conical bulge with the bottom of the lower cover as the bottom and the center of the upper part of the lower cover as the vertex is arranged in the lower cover; an air inlet pipe is arranged in the axis position of the conical bulge, and the inner diameter of an inlet port of the air inlet pipe is gradually reduced; the conical bulge is sleeved with an inner valve; a conical pipe is mounted on the outer side surface of the conical bulge; a support is arranged on the inner wall of the conical pipe, and the other end of the support is contacted with the outer side surface of the conical bulge, so that a gap exists between the conical pipe and the conical bulge; a stepped-shaft valve plate is arranged at the upper part of the inner valve, the outer diameter of the upper part of the stepped-shaped valve plate is larger, the outer diameter of the lower part of the stepped-shaped valve plate is smaller, and the lower end of the stepped-shaped valve plate is aligned to the smaller end of the conical pipe and the inlet port of the air inlet pipe; the upper cover is arranged on the lower cover. According to the medical vaporizer, the stepped-shaped valve plate is arranged at the inlet port of the air inlet pipe, so that vaporized liquid can collide with the stepped valve plate twice after driven by high-pressure air flow and then is blown out by the air flow, the effect is good, the influence of the covers on vaporization quality is eliminated, and the interchangeability is improved.
Description
Technical field
The invention belongs to pressurized nebulizer technical field, particularly relate to a kind of medical vaporizer.
Background technology
Pressurized nebulizer is a kind of atomization of liquid instrument be widely used, and is used for prevention and therapy respiratory system disease in medical treatment.In the prior art, atomized liquid is driven by pressure-air and collides with nebulizer upper cover, and drop, because clash into the less of volume change, is atomized.Therefore in atomization, have higher requirement for the inner wall shape of upper cover, cannot exchange between various different nebulizer.And drop is only in upper cover generation primary collision in atomization process, and atomizing effect is poor.In prior art, internal valve venthole is generally less than 2MM, and production control requires higher.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of medical vaporizer, the input port of air inlet pipe arranges a valve block in trapezoid shaft, twice collision can be carried out with stepped valve block after atomized liquid is driven by high pressure draught, blow out through air-flow again, atomizing effect is good, atomized liquid can not contact with upper cover, eliminates the impact of lid on atomization quality.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of medical vaporizer, comprise upper cover and lower cover, have in described lower cover one with bottom lower cover the end of for, following lid central upper portion is the conical protrusions on top, the axial location of described conical protrusions is provided with air inlet pipe, the input port internal diameter of described air inlet pipe reduces gradually, in described conical protrusions, cover has internal valve, the lateral surface of described conical protrusions is provided with conical pipe, with support on described conical pipe inwall, the lateral surface of described support other end contact conical protrusions, make to there is gap between conical pipe and conical protrusions, described internal valve top is larger with a top external diameter, the multidiameter valve block that lower outer diameter is less, align in the input port of one end that the lower end of described multidiameter valve block is less with conical pipe and air inlet pipe, cover under described and upper cover is housed.
Described upper cover and lower cover are threaded connection and are installed together.
The injection moulding of described lower cover plastics is made, and mould part corresponding to described lower cover lower edge position is empty avoiding mould.
Described input port internal diameter is more than 2 millimeters.
Gap between described conical pipe and conical protrusions is 0.5 millimeter.
Beneficial effect
The invention has the advantages that, the input port of air inlet pipe arranges a valve block in trapezoid shaft, twice collision can be carried out with stepped valve block after atomized liquid is driven by high pressure draught, blow out through air-flow again, atomizing effect is good, atomized liquid can not contact with upper cover, eliminates the impact of lid on atomization quality, improves interchangeability.

Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of internal valve of the present invention.
Fig. 3 is the longitudinal profile structural representation of internal valve of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
As shown in Figures 1 to 3, a kind of medical vaporizer, comprise upper cover 1 and lower cover 3, have in described lower cover 3 one with bottom lower cover 3 end of for, with the conical protrusions of lower cover 3 central upper portion for top, the axial location of described conical protrusions is provided with air inlet pipe, the input port internal diameter of described air inlet pipe reduces gradually, in described conical protrusions, cover has internal valve 6, the lateral surface of described conical protrusions is provided with conical pipe 8, with support 10 on described conical pipe 8 inwall, the lateral surface of described support 10 other end contact conical protrusions, make to there is gap between conical pipe 8 and conical protrusions, described internal valve 6 top is larger with a top external diameter, the multidiameter valve block 5 that lower outer diameter is less, align in the input port of one end 2 that the lower end 4 of described multidiameter valve block 5 is less with conical pipe 8 and air inlet pipe, described lower cover 3 is equipped with upper cover 1.
Together with described upper cover 1 and lower cover 3 are connected and installed by screw thread 7.
Described lower cover 3 plastics injection moulding is made, and the mould part of described lower cover 3 lower edge position 9 correspondence is empty avoiding mould.
Described input port internal diameter is more than 2 millimeters.
Gap between described conical pipe 8 and conical protrusions is 0.5 millimeter.
In real work, high-speed gas enters nebulizer inside through input port, negative region of no pressure can be formed around air-flow, conical pipe 8 and conical protrusions the upper/lower terminal mineralization pressure in gap poor, drive atomized liquid upwards sprays along suction hose 2, twice collision can be carried out with stepped valve block after the atomized liquid sprayed is driven by high pressure draught, again through air-flow blowout, atomizing effect is good, and atomized liquid can not contact with upper cover, eliminate the impact of lid on atomization quality, improve interchangeability.
