Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 4, a heatable hand-held compressed atomizer comprises a cap 2 having a mist outlet 201 and a housing 1 having a liquid medicine chamber 100. The cup cover 2 is arranged at the top of the shell 1 and connected into a whole. An atomization assembly for atomizing the liquid medicine in the liquid medicine cavity 100 is arranged in the shell 1, and the atomization assembly is powered by a power supply in the shell 1 to work. The shell 1 is also provided with a heating device 8 and a heat conducting fin 6, and the heat conducting fin 6 is arranged in the liquid medicine cavity 100. The heat generating portion of the heating device 8 establishes a heat conduction path with the heat conductive sheet 6. The heating means 8 are also operated by power supply within the housing 1. The heat conducting sheet 6 is contacted with the liquid medicine, so that the liquid medicine can be heated to a certain temperature, and the heating device 8 is not contacted with the liquid medicine under the condition of not performing waterproof treatment so as to avoid the incapability of working due to water inflow. The temperature of the final medicine fog can be raised to 30-40 ℃ by heating the liquid medicine, so that the discomfort caused by low temperature is eliminated, and the use experience of a user is improved.

As shown in fig. 3, the atomization assembly comprises a gas transmission pipe 5 and an atomization component 4; the bottom of the gas pipe 5 is connected with a gas source, and the top is provided with a small hole I501 and extends into the cavity of the atomization component 4 to form an up-flow channel 300 communicated with the liquid medicine cavity 100. The atomizing member 4 has a tubular structure having a hollow space so that the gas transmission pipe 5 is inserted therein to form the upper flow path 300. The top of the atomizing part 4 is provided with a small hole II401, the cup cover 2 is internally provided with a baffling column 202, and the bottom of the baffling column 202 is positioned above the small hole II401 of the atomizing part 4 to form a mist outlet gap 400; the heat conducting sheet 6 is disposed below the atomizing member 4 and forms a liquid inlet gap 200 communicating with the upper flow path 300. The aperture of the small hole I501 is smaller than that of the small hole II401, and the diameter of the bottom of the deflection column 202 is larger than that of the small hole II 401.

As shown in FIG. 4, when the atomizing assembly works, air is introduced into the bottom of the air pipe 5 to form an air flow, and when the air flow passes through the small holes I501 and II401 at the top, a Venturi effect is generated to provide motive force for the liquid medicine in the liquid medicine chamber 100 to flow. Under the effect, the flow path of the liquid medicine is the liquid inlet gap 200, the upper flow channel 300, the small hole II401 and the mist outlet gap 400 in sequence. When the liquid medicine passes through the small hole II401, the baffling column 202 is arranged above the small hole II, so that the liquid medicine can be impacted by the airflow to be atomized to form medicine mist, and finally the medicine mist is discharged through the mist outlet 201 to be inhaled by a user.

Specifically, the bottom of the atomizing member 4 has an annular plate 402, and the annular plate 402 of the atomizing member 4 and the heat conductive plate 6 form the inlet gap 200 therebetween. Because the liquid inlet gap 200 generated by the annular sheet 402 is small, the liquid inlet amount is small, so that the liquid medicine can be heated and heated rapidly in the process of flowing through the liquid inlet gap 200.

Preferably, since the amount of liquid fed into the liquid feeding gap 200 is small, the temperature may rise rapidly, and in order to avoid this, the heating device 8 further includes a buffer sheet 7 for reducing the temperature of the heat conductive sheet 6, and the buffer sheet 7 is closely disposed between the heat generating portion of the heating device 8 and the heat conductive sheet 6. The buffer sheet 7 is a silica gel sheet, and the heat conductivity coefficient of the silica gel sheet is lower than that of the heat conducting sheet 6, so that the heat can not be quickly conducted to the heat conducting sheet 6 to cause the rapid temperature rise.

Preferably, the buffer sheet 7 is distributed with a plurality of through holes 701, since the buffer sheet 7 is likely to have too low heat transfer efficiency to heat the chemical solution to a suitable temperature if it completely covers the heat generating portion of the heating device 8. The heat transfer between the heat-conducting fin 6 and the heat generating portion of the heating device is performed through the through hole 701 by the gas in the through hole 701, and the heat transfer efficiency is higher than that of the buffer sheet 7, thereby ensuring that the temperature of the heat-conducting fin 6 can meet the actual requirement.

Preferably, the heating device should be heat-insulated in order to avoid damage to the electrical components by heat generated by the heating device being transferred to the lower space. Therefore, a heat insulation seat 9 is further arranged in the shell 1, the heating device 8 and the heat conducting fins 6 are arranged on the heat insulation seat 9, and the heat insulation seat 9 forms a seal for the bottom of the liquid medicine cavity 100. The heat insulation seat 9 plays a role of heat insulation on one hand, and also plays a role of fixing the heating device 8, the heat conducting sheet 6, the buffer sheet 7 and the heating circuit board on the other hand. The heating circuit board is arranged below the heating device 8, and the heat conducting sheet 6 is positioned at the top of the heat insulation seat 9 and is flush with the top opening. The heat insulation seat 9 is fixed in the shell 1 through screws, and meanwhile, the top heat conduction sheet 6 of the heat insulation seat 9 can also seal the bottom of the liquid medicine cavity 100, so that the liquid medicine is prevented from entering the lower part and short-circuiting an electric element.

Preferably, the compression atomizer further comprises an air pump 10 as an air source, the air pump 10 is arranged in the shell 1 and located in the space of the liquid medicine cavity 100, an air outlet of the air pump 10 is connected with the bottom of the air conveying pipe 5, and an air inlet of the air pump is connected with the outside air through filter cotton. The air pump 10 is also operated by power supplied from a power source. If the compression atomizer is not provided with the air pump 10, the air conveying pipe 5 can be connected with an external air source through an external air pipe.

Preferably, in order to facilitate installation and replacement of internal components, the bottom of the housing 1 is an open structure, and a base 3 is provided, and the base 3 is provided with an air inlet 301.

Preferably, a temperature sensor is provided in the drug solution chamber 100. The temperature sensor collects the temperature of the liquid medicine and feeds the temperature back to the controller, and then the controller controls the temperature of the heating device 8 to realize the adjustment and control of the temperature of the medicine fog. It should be noted that the control method and process may adopt the method in the prior art to realize the adjustment and control of the temperature, and the method is not improved in any way, so that the detailed description is omitted.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
