Abstract

An air blower with functions of air compression, formation of air beam and heat dissipation of circuit board therein includes a main casing; the casing being formed with a wind outlet, a guiding tube, a circular path and a handle; a heating device installed within the guiding tube; an air filter formed around an outer side of the wind inlet; the air filter including a filter mask which is formed around a bottom of the wind inlet and is capable of being detached therefrom; and a separating plate formed within the handle and serving to fix the circuit board and the separating plate separating an inner path of the handle into a circuit board setting chamber and a wind path; and a fan and a motor being installed within the wind path; and the circuit board being installed in the circuit board setting chamber.

1 . An air blower with functions of air compression, formation of an air beam and heat dissipation of a circuit board therein, comprising
 a main casing formed of a first casing and a second casing which are coupled with one another; the first and second casing being formed with buckles; the main casing being formed with a wind outlet, a guiding tube communicated to the wind outlet, a curved path communicated to the guiding tube and a handle communicated to the curved path; a first end of the curved path being communicated to the wind outlet and a second end thereof being communicated to a wind path of the handle; a bottom of the handle being formed with a wind inlet which is communicated to the wind path;   a heating device installed within the guiding tube;   an air filter formed around an outer side of the wind inlet; the air filter including a filter mask which is formed around a bottom of the wind inlet and is capable of being detached therefrom; and   a separating plate formed within the handle and serving to fix the circuit board and the separating plate separating an inner path of the handle into a circuit board setting chamber and the wind path; and   a fan and a motor being installed within the wind path; and the circuit board being installed in the circuit board setting chamber for controlling the fan, the motor and the heating device;   wherein an upper side of the separating plate is formed with a penetrating hole for heat dissipation of the circuit board;   wherein the circuit board is installed on the separating plate; a heating element of the circuit board faces to the penetrating hole of the separating plate and thus to the wind path; and a control element of the circuit board faces to the circuit board setting chamber;   wherein the curved path is communicated to the guiding tube; a first end of the guiding tube is communicated to the wind outlet and a second end of the guiding tube is communicated to the curved path; and the two ends of the guiding tube are communicated with one another so as to form as a hollow tube; and   wherein an air into the handle is guided by the separating plate and flows into the wind path; a cross section of the wind inlet is larger than a cross section of the wind path to cause that the air is compressed in the wind path and is guided into the curved path and flows through the penetrating hole of the separating plate to dissipate heat of the circuit board; the air in the curved path flows around the curved path to the guiding tube; and the guiding tube guides an irregular airflow and turbulent flow into an ordered round or elliptical air beam which is heated by the heating device in the guiding tube and is drained out from the wind outlet of the casing.   
     
     
         2 . The air blower with functions of air compression, formation of the air beam and heat dissipation of the circuit board therein as claimed in  claim 1 , wherein the buckles includes male buckles and female buckles; one side of each male buckle is formed with a slope so that when it is desired to detach the first casing and the second casing, a male buckle can be separated from a female buckle.
