Referring to fig. 1 to 4, the airflow output apparatus includes: main part, handle, air current component, drive arrangement.

The handle is for holding by a user to manipulate the airflow output appliance. The main body is mainly used for outputting airflow.
The airflow element is used for stirring the airflow to enable the airflow to flow; the drive means is for driving the airflow member to move. In a specific embodiment, the airflow component is an axial fan, and the driving device is a motor. When the drive means is energized, the airflow member rotates about an axis to agitate the airflow.
Specifically, the main body comprises an inner peripheral wall and an outer peripheral wall, and at least part of the outer peripheral wall surrounds the inner peripheral wall to form a main body space therebetween; the handle comprises a handle shell wall, and the handle shell wall is used for enclosing a handle space.
The handle is connected to the main body so that the handle space is communicated with the main body space, and the inner peripheral wall is constructed into an annular structure so that a central air duct is surrounded; the main body is provided with an overflowing channel which is communicated with the main body space and the central air duct; the overflowing channel is arranged between the central air outlet and the central air inlet; the handle is provided with a handle air inlet, the airflow element and the driving device are arranged in the handle space, and the handle air inlet and the main body space are respectively positioned at two sides of the airflow element.
As a specific aspect, the inner and outer circumferential walls and other portions of the body may be assembled from a plurality of parts.
According to the scheme, due to the fact that the airflow component stirs the airflow to cause pressure difference, the airflow outside the handle air inlet enters the handle space through the handle air inlet and flows towards the main body space along the handle, the airflow flows to the overflowing channel to enter the central air duct and flows out of the central air duct from the central air outlet of the central air duct to form airflow output due to the fact that the front end (namely the first side) of the main body space is closed, the airflow outside the central air inlet enters the central air duct through the central air inlet due to negative pressure due to the fact that the airflow flowing through the overflowing channel is driven, and therefore airflow flow output by the central air outlet is enhanced. And such wind channel design makes the air current output utensil of this application can export enough amount of wind and comparatively concentrate and comparatively gentle air current, and it has simultaneously not easily by the advantage in foreign matter entering wind channel concurrently.
Preferably, the transfer passage is disposed between the central duct and the main body space such that the transfer passage serves as the only outlet for the air flow in the main body space. Namely, the overflowing channel is arranged between the central air duct and the main body space so as to communicate the central air duct and the main body space; the main body is in a closed structure except for the communication between the central air duct and the handle space, so that the airflow introduced by the handle air inlet enters the central air duct through the main body space and then flows along the central air duct.
As a more specific aspect, the main body further includes a guide wall connected to the inner circumferential wall or the outer circumferential wall to guide the air flow of the main body space through the flow passage at a predetermined angle, the guide wall having at least a guide surface obliquely intersecting the central axis. As the preferred scheme, the range of the included angle between the flow guide surface and the central axis is 13 degrees to 76 degrees.
Specifically, the main body further includes a closing wall connected to the outer circumferential wall or/and the inner circumferential wall to close a front side of the main body space to stop the flow of the air flowing toward the first side in the main body space.
As a specific aspect, the airflow output device further includes: a heater. The heater is used for heating the airflow; the heater is disposed in the main body space so that the air flowing toward the flow passage passes through the heater.
In order to obtain a better air duct effect, the ratio of the distance from the overflowing channel to the end face of the central air duct on the first side to the distance from the overflowing channel to the end face of the central air duct on the second side ranges from 1.35 to 9.05.
In addition, the handle air inlets may be multiple and located at the end of the handle, and the handle air inlets may be arranged in a certain array manner so as to provide a sufficient air inlet area, and as a preferred embodiment, the ratio of the distance from the airflow element to the handle air inlets to the distance from the airflow element to the communication position between the handle space and the main body space (i.e., the air source channel) has a value ranging from 0.28 to 0.92. The distance referred to here is based on the direction of the axis of rotation of the airflow member and is the minimum distance between two objects or spatial positions in the direction of the axis of rotation of the airflow member. The inner side of the air inlet of the handle can be provided with a filter screen and other devices.
As a specific aspect, the airflow output device further includes: a circuit board. The circuit board is at least electrically connected with the driving device; the heater is located between the circuit board and the flow passage. As a more specific aspect, a plurality of circuit boards may be provided in the main body space, and the circuit boards may be configured as a ring structure or a part of a ring structure.
As a further preferable aspect, as shown in fig. 5, in order to obtain a better air flow effect, the main body includes, similar to the first embodiment: the inner peripheral wall, the outer peripheral wall, the closing wall and the flow guide wall. Specifically, the inner circumferential wall is used for enclosing at least one part of the central air duct; the outer circumferential wall is used for surrounding the inner circumferential wall so that a main body space is formed between the outer circumferential wall and the inner circumferential wall; the closing wall is used for stopping the air flow in the main body space from flowing out of the first side of the main body; the flow guide wall is used for guiding the airflow flowing to the second side of the main body in the main body space to the flow passage arranged on the main body; wherein, in the direction that central wind channel extends, the closed wall is close to main part first side relatively, and the guiding wall is close to the main part second side relatively.
More specifically, the flow passage is relatively close to the second side of the main body. This makes it easier to draw the air flow at the central air inlet.
The guide wall at least partially forms a channel wall of the overflowing channel, and the inner peripheral wall at least partially bends to form the channel wall of the overflowing channel.
Specifically, the circuit board is disposed in the main body space at a position relatively close to the closing wall, and the heater is disposed in the main body space at a position relatively close to the guide wall, in a direction in which the central duct extends.
The peripheral wall is provided with an air supply passage for introducing an air flow generated by the air flow source into the main body space, such as the above-mentioned communication between the handle space and the main body space, although other modes of air supply passages may be constructed. As a specific solution, the air supply channel is arranged between the closing wall and the flow guiding wall in the direction in which the central air duct extends. The air supply passage is at least partially disposed between the circuit board and the heater in a direction in which the central air duct extends.
Through such setting, can make circuit board self can by effectual heat dissipation, carry the air current that the circuit board gived off the heat simultaneously also by heating to a certain extent, kill two birds with one stone. And the air current heated by the heater does not flow through the circuit board, thereby ensuring that the circuit board and the electric elements installed on the circuit board are not overheated.
As a further preferable aspect, the airflow output device of the present application further includes: a flow divider. The shunt piece is used for enabling a part of the airflow from the air source channel to flow to the circuit board and a part of the airflow to flow to the heater; the shunt member is disposed between the circuit board and the heater in a direction in which the central air passage extends.
More specifically, the heater is disposed between the flow dividing member and the flow guide wall in a direction in which the central air passage extends. The circuit board is arranged between the splitter and the closing wall in the direction in which the central air duct extends.
The adoption of the flow dividing piece can ensure that the airflow can radiate the circuit board, and simultaneously can shorten the distance of airflow backflow from the air source channel, so that a part of airflow does not need to reach the closed wall or flow to the overflowing channel in the reverse direction after being stopped by the circuit board, and the loss of airflow flow speed caused by shielding is reduced.
Preferably, the central air duct has at least two cross-sections with different areas for better air output of the central air duct. The central duct extends through opposite sides of the main body, and defines one side of the input airflow as a front side (first side) of the main body and one side of the output airflow as a rear side (second side) of the main body.
Specifically, the central air duct includes in order from the main body rear side to the front side: a current collecting section, a current converging section and a jet flow section.
The cross section of the collecting section is gradually reduced from the rear side of the main body to the front side of the main body; the cross section of the confluence section is gradually reduced from the rear side of the main body to the front side of the main body; the cross-section of the jet section increases from the rear side of the body to the front side of the body. With the adoption of the scheme, the air flow can effectively suck the external air flow in the central air duct at the collecting section, the collecting section can enable the two air flows to be combined, and the combined air flow has high flow speed. The jet section provides a softer output of the gas stream.
More specifically, the flow passage is disposed between the collector section and the bus section. The length of the jet flow section is greater than that of the collecting section. The length of the jet flow section is greater than the length of the confluence section. The length of the jet flow section is greater than or equal to the sum of the lengths of the current collecting section and the bus section. By such a design, the air flow can be adjusted in the central air duct, thereby obtaining the desired effect.
The minimum cross section of the central air duct is the junction of the confluence section and the jet flow section. By adopting the scheme, stronger pressure can be generated by the airflow output by the flow passage.
The central air duct is of a revolving body structure. Therefore, when the air flow is output, the condition of unbalance cannot be generated in the central air duct.
The flow guiding direction of the overflowing channel is tangent to the air duct wall of the confluence section of the central air duct. This further reduces the resistance to the airflow, thereby ensuring the flow rate of the airflow.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
