Description:
TECHNICAL FIELD 
       [0001]    This utility model relates to an inhalation device, in particular, an aerosolizing inhalation device that aerosolizes the solution with the substance of physiologic activity into aerosol and delivers it into lungs via the respiratory tract. 
       BACKGROUND 
       [0002]    With regard to existing aerosolizing lung inhalation devices for medical purposes, a broad range of ultrasonic atomizers are available for clinic and family use. However, the diameter of aerosol particles from the existing aerosolizing devices are large, and most aerosol particles are retained by the upper respiratory tract and bronchus. As a result, they cannot effectively reach the bronchiole or alveolus. In addition, such devices are not easy to carry due to their big sizes.

     DETAILED DESCRIPTION 
       [0018]    As shown in  FIG. 1 , in accordance with an embodiment, the invention includes a housing ( 2 ), and a battery ( 3 ), a pneumatic switch ( 4 ), an atomizer ( 6 ) and a liquid-supplying bottle ( 7 ), all of which are arranged in turn and disposed in the housing ( 2 ), which is a hollow cylinder, on the front of which is an indicator ( 1 ). The liquid-supplying bottle ( 7 ) is provided with a vent duct ( 8 ), and one end of the liquid-supplying bottle ( 7 ) is connected to the atomizer ( 6 ). On the other side of the atomizer ( 6 ), there are the pneumatic switch ( 4 ) and battery ( 3 ) successively. The battery ( 3 ), pneumatic switch ( 4 ) and atomizer ( 6 ) are in series connection to form a loop. The pneumatic switch ( 4 ) controls the operation of the atomizer ( 6 ). In this example, the pneumatic switch ( 4 ) is a mechanical switch made of rubber film and metal and driven by pressure difference. Alternatively, it may be a Hall element, semiconductor force-sensitive chip, silicon matrix bridge chip, capacitance or induction sensor. The housing ( 2 ) is provided with an air orifice ( 5 ) between the pneumatic switch ( 4 ) and atomizer ( 6 ) for air inhalation from outside. 
         [0019]    As shown in  FIGS. 2 and 3 , in accordance with an embodiment of the invention, atomizer ( 6 ) is a jet heating atomizer that includes the liquid-supplying structure ( 101 ) and heating body ( 102 ). The liquid-supplying structure ( 101 ) is a porous structure or fiber structure, on one end of which there is a jet hole ( 103 ), while on the other end, there is a protuberance ( 104 ). The jet hole ( 103 ) is made of foamed ceramics, micro-porous ceramics, foamed metal, stainless steel fiber felt or chemical fiber through molding and drilling. The heating body ( 102 ) is located inside the liquid-supplying structure ( 101 ), electrically connected with the battery ( 3 ), and controlled with the pneumatic switch ( 4 ). The liquid-supplying bottle ( 7 ) contacts the protuberance ( 104 ), so that the aerosolizing liquid can penetrate into the liquid-supplying structure ( 101 ). The heating body ( 102 ) is a micro-porous ceramic framework with Ohmic metal electro-thermal material or a porous component created with electrically conductive ceramics/PTC material, which is associated with sintered electrode. The jet heating atomizer carries out the primary atomization in the jet hole ( 103 ) with the suction airflow, and then the secondary atomization by spraying onto the heating body ( 102 ). The atomization for twice enables even atomization, and small aerosolized particles with a mean diameter of about 1 μm, which is the most optimal technical parameter for lung inhalation. 
         [0020]    As shown in  FIGS. 4 and 5 , in accordance with an embodiment of the invention, atomizer ( 6 ) is an impregnation atomizer, which includes the liquid-supplying structure ( 201 ) and heating body ( 202 ). The liquid-supplying structure ( 201 ) is a porous structure or fiber structure, on one end of which is a protuberance ( 204 ), while on the other end is the heating body ( 202 ). The heating body ( 202 ) is electrically connected with the battery ( 3 ), and controlled with the pneumatic switch ( 4 ). The liquid-supplying bottle ( 7 ) contacts the protuberance ( 204 ), so that the aerosolizing liquid can penetrate into the liquid-supplying structure ( 201 ). The heating body ( 202 ) is a micro-porous ceramic framework with Ohmic metal electro-thermal material or a porous component created with electrically conductive ceramics/PTC (Positive Temperature Coefficient) material, which is associated with sintered electrode. The impregnation atomizer leverages the heating body ( 202 ) to directly heat the liquid-supplying structure ( 201 ), thus aerosolizing the solution. 
         [0021]    In an embodiment, on one end of the atomizer ( 6 ) in the above-mentioned two examplary embodiments, the protuberances ( 104 ,  204 ) are connected with the liquid-supplying bottle ( 7 ). The aerosolizing solution in the liquid-supplying bottle ( 7 ) enters the atomizer ( 6 ) through the liquid-supplying structure ( 101 ,  201 ). The liquid-supplying structure ( 101 ,  201 ) is made of foamed ceramics, micro-porous ceramics, perforated metal, stainless steel fiber felt or chemical fiber through molding and drilling. The heating body ( 102 ,  202 ) is a micro-porous ceramic framework with Ohmic metal electro-thermal material or a porous component directly created with electrically conductive ceramics/PTC material, which is associated with sintered electrode. The surface of the heating body ( 101 ,  202 ) is sintered into high-temperature glaze to fix the zeolite grains, which are made of natural zeolite, artificial non-organic micro-porous ceramics or aluminum oxide grains. 
         [0022]    In an embodiment, the invention operates as follows: The medicine is dissolved with propanediol, and the aerosolizing solution is put into the changeable liquid-supplying bottle ( 7 ). The liquid-supplying bottle ( 7 ) is put into the housing ( 10 ), contacts the atomizer ( 6 ), and supplies the liquid to it. When the user sucks, the pneumatic switch ( 4 ) accomplishes the mechanical contact under the action of pressure difference, connecting the battery ( 3 ) with the atomizer ( 6 ). The battery ( 3 ) electrifies the atomizer ( 6 ), and the heating body ( 102 ,  202 ) starts to heat. When the user sucks, the indicator ( 1 ) is lit, and the atomizer ( 6 ) condenses and dilutes the air in the liquid-supplying bottle ( 7 ), thus making mist, which is sucked out through the vent duct ( 8 ) on the liquid-supplying bottle. 
         [0023]    The fiber structure for production of the liquid-supplying bottle and liquid-supplying structure is made of chemical fiber or nylon fiber. 
         [0024]    The atomizer of this invention atomizes the aerosolizing solution impregnated from the liquid-supplying bottle, and the mist is diluted with the inhaled air into aerosol, which is inhaled by the user. In an embodiment, the invention may be used as cigarette substitute or as medical device delivering medicine to lungs.
