Description

FIELD OF THE INVENTION

The present invention is related to, and in particular to air blowers, and in particular to an air blower with functions of air compression, formation of air beam and heat dissipation of circuit board therein, in that 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. Air flow enters through a filter in the wind inlet and then flows in the wind path to absorb heat dissipated from the circuit board and then is compressed as a wind beam so as to be formed as ordered round or elliptical airflow which is heated by a heat device and then is dissipated from a wind outlet.

BACKGROUND OF THE INVENTION

There are many prior arts are related to air blowers (i. e. hair dryers, gas blowers), in fact, air blowers are indispensable in daily life for people. There are many inventions related to air blowers, such as U.S. Pat. Nos. 11,033,088B2, 10,869,529B2, 10,687,595B2, 10,441,049B2, 10,226,112B2, 10,213,001B2, 10,165,843B2, 10,085,538B2, 10,080,414B2, 10,021,951B2, 10,004,313B2, 9,986,810B2, 9,808,065B2, 9,420,864B2, etc.
In conventional air blowers, fan and motor suck air into the blower bodies. Then air is heated and is dissipated for use. In the flow path, air enters into the suction opening at an upper rear end the air blower, then the air being heated along a straight flow line by a heating device. Finally, the air is drained out of the casing of the air blower body. However, this prior art design has the defects that the mass center is concentrated at an upper section of the air blower so that the wrist and arm of the user feel ache and tired as using for a long time.
Therefore, there are many designs which aim to change the mass center of the air blower in the conventional technology. In one design the air inlet is modified to be at a bottom of the handle of the air blower and the fan, motor and other elements are arranged at the inner bottom of the air blower so as to lower the mass center of the air blower, while in this improvement design, the fan, motor, and other elements are mixed with the circuit board and sucked airflow at the same space, as a result, turbulent flow generates. Furthermore as the air flows through the heating device, the turbulent flow causes that heating process is not uniform and the turbulent flow becomes more dramatic and disorder,
Therefore, there is an eager demand for a novel air blower, which causes the air in the air blow is as a beam like wind with exists less turbulent. Furthermore the temperature of the circuit board in the air blower can be reduced effectively. Moreover, hairs, dregs and dusts in the outer side of the air blower are not sucked into the air blower. All the prior art defects are necessary to be improved for a novel designed air blower.

SUMMARY OF THE INVENTION

Accordingly, the object of the present invention is to provide an air blower with functions of air compression, formation of air beam and heat dissipation of circuit board therein, wherein a separating plate separates the inner space of the air blower into an air inlet path and a circuit board setting chamber so that the mass center of the air blower will not be concentrated in the palm. Thus the air blower is more light and compact. Furthermore, in the present invention, since the separating plate separates the inner space of the air blower into an air inlet path and a circuit board setting chamber, the penetrating hole in the separating plate will cause the air flow can flow into the circuit board setting chamber to dissipate heat generated in the circuit board. The heat from the circuit board can be used to reduce the heat power of the air blower. The temperature of the circuit board can be decreased effectively, while air flow in the air blower does not influent by the temperature reduction of the circuit board. A bottom of the handle is formed with an air filter which has a plurality of filtering functions so as to effectively hinder the entrance of the air, dregs, or dusts in the air and therefore, the lifetimes of the fan and motor are prolonged. The circular path and the guiding tube installed in the casing can guide the airflow therein sufficiently and smoothly so that the heat distribution is more uniform, heat flow is more rapid and accurate.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
Referring to FIGS. 1 to 4 , the structure of the air blower (hair dryer, gas blower) the present invention is illustrated. The present invention includes the following elements. A first casing 1A and a first casing 1B which are coupled as the casing 1 of the present invention. An inner side of the first casing 1A is formed with a plurality of male buckles 1C and an outer side of the second casing 1B is formed with a plurality of female buckles 1D. The first casing 1A is buckled to the second casing 1B by the male buckles 1C to be buckled to the female buckles 1D. One side of each male buckle is formed with a slope 1C1 so that when it is desired to detach the first casing 1A and the second casing 1B, the male buckles 1C can be easily separated from the female buckle 1D.
An upper side of the casing 1 is formed with a wind outlet 11. An inner side of the casing 1 is formed with a circular flow path 12. A flow guiding tube 13 is formed between the circular path 12 and the wind outlet 11. A heating device 3 is installed within the guiding tube 13. The heating device 3 is actuated by a circuit board 2. One end of the circular path 12 is communicated to the wind outlet 11 and another end of the circular path 12 is communicated to a wind path 41. The wind path 41 is formed as a lower handle 4 of the casing 1.
Referring to FIG. 5 , a bottom of the handle 4 is formed with a wind inlet 40 which is communicated to the wind path 41. An air filter is formed around an outer side of the wind inlet 340. The air filter includes a filter mask 5 is formed around the bottom of the wind inlet 40 and is capable of being detached therefrom. The filter mask 5 is formed with penetrating holes 50. An inner side of the filter mask 5 is installed with a filtering layer 6A and a filtering layer 6B which have different air venting effect. Referring to FIG. 6 , the filtering layer 6A is formed by fiber material (such as PET material, non-weave material, electric static proof material, or active carbon material, etc.). The penetrating holes in the filtering layer 6A are irregular circular or folded paths for preventing hair to be absorbed thereinto.
Referring to FIGS. 1 to 4 , a separating plate 14 is formed within the handle and serves to fix the circuit board 2 and the separating plate 14 separates an inner path of the handle 4 into a circuit board setting chamber 15 and a wind path 41. A fan 7A and a motor 7B are installed within the wind path 41. The circuit board 2 is installed in the circuit board setting chamber 15 for controlling the fan 7A, the motor 7B and the heating device 3. An upper side of the handle 4 is formed with a penetrating hole 140 for heat dissipation of the circuit board 2. The circuit board 2 is installed on the separating plate 41. The heating elements of the circuit board 2 faces to the penetrating hole 140 and thus to the wind path 41. The control elements of the circuit board 2 faces to the circuit board setting chamber 15.
Referring to FIGS. 1 to 4 and 12 to 18 , two ends of the guiding tube 13 are communicated with one another so as to form as a hollow tube. The wind inlet end 13 a of the guiding tube 13 has a hollow plane non-round shape. The wind outlet end 13 b of the guiding tube 13 has a hollow plane round shape. The guiding tube 13 is formed between the circular path 12 of the casing 1 and the wind outlet 11 of the casing 1. The wind outlet end 13 b of the guiding tube 13 is communicated to the wind outlet 11 and the wind inlet 13 a of the guiding tube 13 is communicated to the circular path 12. The guiding tube 13 is not communicated to other space of the casing 1.
When the circuit board 2 receives a start signal, the circuit board 2 controls the fan 7A, the motor 7B and the heating device 3 to actuate. The wind outside the casing 1 will be sucked from the wind inlet 40. The filter out of the wind inlet 40 will remove the hairs, dregs and dusts in air. Air into the handle 4 is guided by the separating plate 14 and then flows into the wind inlet path 41. Since the cross section of the wind outlet 11 is larger than the cross section of the wind inlet path 41, the air will be compressed in the wind inlet path 41 and then is guided into the circular path 12. At the same time, air also flows through the penetrating hole 140 and thus to dissipate heat of the circuit board 2. The air in the circular path 12 will further flow around the circular path 12 and then to the guiding tube 13. The guiding tube 13 will guide the irregular airflow and turbulent flow into an ordered round or elliptical air beam which is heated by the heating device 3 in the guiding tube 13 and then is drained out from the wind outlet 11 of the casing 1.
Advantages of the present invention will be described hereafter. In the present invention, the separating plate separates the inner space of the air blower into an air inlet path and a circuit board setting chamber so that the mass center of the air blower will not be concentrated in the palm. Thus the air blower is more light and compact. Furthermore, in the present invention, since the separating plate separates the inner space of the air blower into an air inlet path and a circuit board setting chamber, the penetrating hole in the separating plate will cause the air flow can flow into the circuit board setting chamber to dissipate heat generated in the circuit board. The heat from the circuit board can be used to reduce the heat power of the air blower. The temperature of the circuit board can be decreased effectively, while air flow in the air blower does not influent by the temperature reduction of the circuit board. A bottom of the handle is formed with an air filter which has a plurality of filtering functions so as to effectively hinder the entrance of the air, dregs, or dusts in the air and therefore, the lifetimes of the fan and motor are prolonged. The circular path and the guiding tube installed in the casing can guide the airflow therein sufficiently and smoothly so that the heat distribution is more uniform, heat flow is more rapid and accurate.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
