Examples

Fig. 1 is a schematic structural diagram of a first view angle of a fumigation inhaler 100 provided in an embodiment of the present application, fig. 2 is a schematic structural diagram of a second view angle of a fumigation inhaler 100 provided in an embodiment of the present application, and fig. 3 is a schematic structural diagram of a third view angle of a fumigation inhaler 100 provided in an embodiment of the present application. Referring to fig. 1-3, the fumigant inhaler 100 includes a vaporizer 110, a reservoir 120, a fluidic mechanism 130, and a pipette (not shown). The fumigation inhaler 100 utilizes the jet principle of the jet mechanism 130 to mix the liquid in the evaporator 110 and the liquid in the liquid reservoir 120, thereby avoiding the loss of drug effect caused by direct boiling heating.

Referring to fig. 4 and 5, the evaporator 110 has a containing cavity for containing liquid therein, and the liquid in the containing cavity can be heated by the heater to generate steam. Optionally, the liquid in the containment chamber is water.

In some specific embodiments, the evaporator 110 includes an atomizing barrel 111, a partition 113, and a steam release cover 115. The atomizing barrel 111 is generally in a long cylindrical shape, and the atomizing barrel 111 may be made of a high temperature resistant material, such as ceramic or stainless steel. The partition 113 is hermetically connected with the atomizing barrel 111, the atomizing barrel 111 and the partition 113 enclose to form the accommodating cavity, the partition 113 is provided with a steam exhaust hole 1131, and the steam exhaust cover 115 is provided with a steam exhaust hole 1151; the steam release cover 115 can be rotated relative to the partition 113 to adjust the overlapping area of the steam exhaust 1131 and the steam release 1151.

For example, the partition 113 and the atomizing barrel 111 may be detachably connected, for example, a screw thread connection or a snap connection between the partition 113 and the atomizing barrel 111. Wherein, can improve the isolator 113 and the atomizing bucket 111 gas tightness through setting up waterproof rubber ring 117 between isolator 113 and the atomizing bucket 111, prevent to hold the steam leakage of intracavity. Wherein, the waterproof rubber ring 117 may be an O-shaped rubber ring.

In addition, the steam release cover 115 may be rotatably connected to the atomizing barrel 111, and the steam release cover 115 may also be rotatably connected to the partition 113. Illustratively, referring to fig. 6, a plurality of spaced-apart outer annular ribs 1133 are disposed circumferentially about the partition 113, with adjacent outer annular ribs 1133 defining slots 1135 therebetween. The steam release cover 115 includes a top cover and a cover wall connected to the periphery of the top cover, and an inner annular rib (not shown) is provided on the inner wall of the cover wall. The specific fit relationship between the outer annular rib 1133 and the inner annular rib is: the inner annular rib moves closer to the outer annular rib 1133, the inner annular rib enters and passes through the clamping groove 1135, and the inner annular rib and the outer annular rib 1133 rotate relatively and the outer annular rib 1133 and the inner annular rib are kept in contact by rotating the steam release cover 115. When it is desired to remove the cover 115, the cover 115 is rotated so that the inner annular rib moves along the groove 1135 away from the spacer 113 until the cover 115 is removed from the spacer 113.

In this application, the vapor escape path for water in the chamber after boiling to evaporate is divided into two paths, one for water to flow out of the fluidic mechanism 130 and the other for water to escape through the vapor vent 1151. Under the same condition, the evaporation amount of water in unit time is constant, and if the flow rate of steam entering the jet mechanism 130 is required to be changed, the steam discharge amount of the steam discharge cover 115 in unit time can be adjusted. In the present application, the steam release cover 115 rotates clockwise or counterclockwise to change the overlapping area of the steam exhaust holes 1131 and the steam release holes 1151, so as to change the cross-sectional area of the steam exhaust from the steam release cover 115, change the steam exhaust speed of the steam release cover 115, equivalently adjust the steam escape speed of the nozzle, and change the escape speed to slow down or accelerate the supply of the liquid medicine in the liquid storage cavity 121, thereby changing the amount of mist generated in unit time. The patient can selectively control the amount of the generated mist in unit time according to the requirement of the patient by rotating the steam release cover 115. For example, when the amount of mist formed by mixing the liquid medicine with the steam is too large and the amount of mist inhaled by the patient per unit time is too large, the patient feels a significant discomfort, the steam can be released by rotating the steam release cap 115, the released steam can be exhausted to the outside of the housing 140 through the steam guide pipe, both ends of the steam guide pipe are provided with openings, the steam release hole 1151 is communicated with one end of the steam guide pipe, the other end of the steam guide pipe is disposed outside the housing 140, and the steam in the steam release hole 1151 is exhausted to the outside of the housing 140 through the steam guide pipe.

In a specific arrangement, an atomizing nozzle may be employed to atomize the gas.

In other specific embodiments, the heater may be an electric heater. Wherein, the electric heater can be arranged in the accommodating cavity and also can be arranged outside the accommodating cavity. Illustratively, the electric heater is disposed outside the receiving chamber, i.e., outside the atomizing barrel 111. The electric heater comprises an electric heating plate for heating, a key switch and a power supply device. Alternatively, the electric heating plate is connected to the atomizing barrel 111 by screws. Wherein, the electric hot plate is connected with the key switch in series and the power supply device, after the power supply device supplies power to the electric hot plate, the heat generated by the electric hot plate is used for heating the outer wall of the atomizing barrel 111, and the key switch is used for controlling the circuit to be closed.

That is, one end of the pipette communicates with the liquid inlet passage, and the other end of the pipette is disposed in the liquid storage chamber 121. The pipette may be made of a polyvinyl chloride (PVC) material, among others. Further, the material may be polypropylene (PP), Polyethylene (PE), or the like.

The jet mechanism 130 is a jet device utilizing the venturi effect. The venturi effect is that low pressure is generated near fluid (liquid or gas) flowing at high speed, so that adsorption is generated. In this application, the water that holds the intracavity is heated to the boiling, water vaporization forms steam, steam enters into to the nozzle and escapes along admission passageway, near nozzle forms the negative pressure, produce the adsorption, inlet channel receives the adsorption and inhales the liquid medicine, liquid medicine and steam contact, high temperature steam heats the liquid medicine, form the fog with steam mixing after the liquid medicine vaporization, thereby avoided directly boiling the liquid medicine and leaded to the drug effect to lose, in addition, the liquid medicine that is in room temperature environment mixes with the steam of high temperature, can avoid the fog temperature that the two mixes the formation too high or low excessively to a certain extent, the stimulation to the affected part has been reduced.
