[0028] The following description, in conjunction with the accompanying drawings, details specific embodiments of the present invention. The detailed description and drawings below are provided to exemplify the principles of the invention; however, the invention is not limited to the described preferred embodiments, and the scope of protection of the invention is defined by the claims.

[0029] like Figs. 1-6 As shown, an embodiment of the present invention provides a drone 100, which includes a main body 100, a power unit, and a first solenoid valve 400 (the first solenoid valve 400 in the figure is a schematic diagram showing the installation position).

[0030] The main body 100 is the main frame of the drone. Other components of the drone can be mounted on the main body 100. Other functional components carried by the drone, such as cameras, can also be mounted on the main body 100.

[0031] The main body 100 includes a power chamber 110, which provides installation and working space for the power equipment. The main body 100 also has an air inlet 120 and an exhaust outlet, both of which communicate with the power chamber 110. The air inlet 120 can be formed by multiple air intake holes on the peripheral wall of the power chamber 110. Multiple air intake holes ensure uniform air intake into the power chamber 110 and allow air to be drawn in from multiple directions, guaranteeing sufficient air supply. The exhaust outlet can be located below the main body 100 and face downwards.

[0032] The power unit can pressurize or accelerate the air entering through the air inlet 120. When the pressurized or accelerated air is discharged from the exhaust port, it can provide an upward thrust to the main body 100. When the upward thrust is greater than the weight of the drone, it can lift the drone. When the upward thrust is less than the weight of the drone, the drone descends.

[0033] The power unit is located inside the power chamber 110 and pressurizes or accelerates the air that enters the power chamber 110 from the air inlet 120.

[0034] The first solenoid valve 400 is configured to control the opening and closing of the exhaust port, allowing the exhaust port to be closed, fully open, or partially open. This allows the user to control the degree of opening and closing of the exhaust port via the first solenoid valve 400, thereby controlling the discharge of pressurized or accelerated air and thus controlling the drone's flight direction and speed.

[0035] In the drone of this embodiment, the power unit pressurizes or accelerates air drawn in from outside the drone through the air inlet 120, and then exhausts it through the exhaust port. The exhaust pressurized or accelerated air generates thrust on the drone, thereby driving it to move. The first solenoid valve 400 controls the opening and closing of the exhaust port, allowing the user to control the degree of opening and closing of the exhaust port to control the exhaust of pressurized or accelerated air, thus controlling the drone's flight direction and speed. The drone of this embodiment adopts a bladeless design, resulting in low noise, low wind resistance, and minimal impact on flight even in strong winds.

[0036] In this embodiment of the invention, the power equipment includes a compressor 200 and a motor 300. The compressor 200 can pressurize the air entering from the air inlet 120. The motor 300 is used to drive the compressor 200.

[0037] In this embodiment of the invention, the power equipment includes a high-speed fan and a motor 300. The high-speed fan can accelerate the air entering from the air inlet 120. The motor 300 is used to drive the high-speed fan.

[0038] Of course, in other embodiments of the present invention, the power equipment may simultaneously include a compressor and a high-speed fan, which can simultaneously pressurize and accelerate the air entering from the air inlet 120. The accompanying drawings of this application only show the case where the power equipment includes a compressor 200 and a motor 300.

[0039] In this embodiment of the invention, the main body 100 further includes a first exhaust pipe 130, which communicates with the power chamber 110. The first exhaust pipe 130 has a first air outlet 131, which is the exhaust port of the main body 100, and the first air outlet 131 faces downwards from the drone. After setting the first exhaust pipe 130, it is only necessary to ensure that the first air outlet 131 faces downwards from the drone. The location of the exhaust opening on the power chamber 110 in the main body 100 is relatively free; the exhaust opening on the power chamber 110 can be located on the outer periphery or bottom of the main body 100.

[0040] In this embodiment of the invention, the main body 100 includes at least three first exhaust pipes 130, which are evenly distributed on the outer periphery or bottom of the power chamber 110. By providing at least three first exhaust pipes 130 and exhaust ports, the opening and closing degree of the exhaust ports can be controlled separately, thereby allowing individual control of the thrust generated at each exhaust port. This allows the thrust at each exhaust port to be adjusted according to user needs, causing the drone to deflect and thus changing its flight direction.

[0041] The first solenoid valve 400 is installed inside the first exhaust pipe 130. The first solenoid valve 400 is used to control the opening and closing of the first exhaust port 131. The first exhaust pipe 130 provides installation space and a mounting base for the first solenoid valve 400. By controlling the degree of opening and closing of the first solenoid valve 400, the degree of opening and closing of the first exhaust port 131 can be controlled, which in turn controls the degree of opening and closing of the exhaust port.

[0042] like Figs. 1-3 As shown, by setting three exhaust ports and three first exhaust pipes 130, the drone can be deflected in various directions. Of course, more exhaust ports and first exhaust pipes 130 can also be set. With more exhaust ports and first exhaust pipes 130, the multiple first exhaust pipes 130 are evenly distributed on the outer periphery or bottom of the power cavity 110, which can more accurately control the deflection direction of the drone.

[0043] like Fig. 5 As shown in the embodiment of the invention, the main body 100 further includes a second exhaust pipe 140. The second exhaust pipe 140 is connected to the power chamber 110 and has a second air outlet 141 facing the side of the drone. Air pressurized or accelerated by the power equipment can be discharged from the side of the drone through the second exhaust pipe 140 and the second air outlet 141. The pressurized or accelerated air can provide thrust to the drone from the side, and this thrust, in conjunction with the thrust at the first air outlet 131, can propel the drone to the designated location more quickly.

[0044] In fact, in the aforementioned embodiments, by setting multiple first exhaust pipes 130, the drone can be deflected in various directions, allowing it to reach any location specified by the user. In this embodiment, a second exhaust pipe 140 is also provided, which is equivalent to adding lateral thrust to the drone, enabling it to be propelled to the designated location more quickly.

[0045] The drone also includes a second solenoid valve 500 (the second solenoid valve 500 in the attached diagram is a schematic diagram showing its installation location), which is installed inside the second exhaust pipe 140. The second solenoid valve 500 is used to control the opening and closing of the second exhaust port 141, thereby controlling the thrust provided at the second exhaust port 141 as needed.

[0046] Of course, multiple second exhaust pipes 140 can be provided, and the multiple second exhaust pipes 140 are evenly distributed on the outer periphery or bottom of the power chamber 110. Each second exhaust pipe 140 is equipped with a second solenoid valve 500 to control the opening and closing of the second air outlet 141.

[0047] In this embodiment of the invention, the air inlet 120 is located above the main body 100, that is, at a position slightly above the main body 100. The air inlet 120 may be formed by multiple air inlets located slightly above the peripheral wall of the power chamber 110.

[0048] The exhaust port is located below the main body 100, specifically at a lower position. Without the first exhaust pipe 130, the exhaust opening on the power chamber 110 is the exhaust port in this embodiment of the invention. This opening is located below the main body 100 and faces downwards, and the first solenoid valve 400 is directly installed at this opening. With the first exhaust pipe 130, the exhaust opening on the power chamber 110 can be located at a lower position on the peripheral wall of the main body 100 or at the bottom; the opening's orientation is not limited. The first outlet 131 of the first exhaust pipe 130 is the exhaust port, and it faces downwards.

[0049] The power unit is located between the air intake 120 and the exhaust port, facilitating the pressurization or acceleration of air drawn in through the air intake 120 and the discharge of pressurized or accelerated air through the exhaust port. When the pressurized or accelerated air is discharged from the exhaust port, it provides an upward thrust to the main body 100. When the upward thrust is greater than the weight of the drone, the drone can be lifted. When the upward thrust is less than the weight of the drone, the drone descends.

[0050] In this embodiment of the invention, the main body 100 further includes a support plate 150, which is located inside the power cavity 110, and the power equipment is disposed on the support plate.

[0051] When the power equipment includes a compressor 200 and a motor 300, the compressor 200 and motor 300 are mounted on a support plate 150. During installation, the motor 300 and compressor 200 can be first mounted on the support plate 150 to form a single unit, and then this unit can be installed into the power chamber 110. A stepped structure can also be provided above the power chamber 110, which can be used to position the power equipment and the support plate. When pressurized air is discharged from the exhaust port, the resulting reaction force can push the unit formed by the motor 300, compressor 200, and support plate 150 against the stepped structure, making the installation more stable.

[0052] In the case where the power equipment includes a high-speed fan and a motor 300, the high-speed fan and motor 300 are mounted on the support plate 150. During installation, the motor 300 and the high-speed fan can be first mounted on the support plate 150 to form a whole, and then this whole can be installed into the power chamber 110. A stepped structure can also be provided above the power chamber 110, which can be used to position the power equipment and the support plate. When the accelerated air is discharged from the exhaust port, the resulting reaction force can push the whole formed by the motor 300, the high-speed fan, and the support plate 150 against the stepped structure, making the installation more stable.

[0053] like Fig. 4 , Fig. 6 As shown in the embodiment of the invention, the drone also includes a sensor 600, a controller, a processor, etc. The sensor 600 can detect parameters such as airflow velocity, flow rate, and pressure, and transmit the detected parameters to the processor. The user can input their requirements as needed, and the processor can process the user's input requirements and the parameters detected by the sensor 600. The controller can then control the opening or closing of the first solenoid valve 400 and the degree of opening of the second solenoid valve 500, thereby fulfilling the user's requirements.

[0054] In this embodiment of the invention, the drone also includes a dryer 700, which is located at the point where the airflow passes through. The dryer 700 can absorb moisture in the airflow, prevent electronic components from getting damp, and protect the components inside the drone.

[0055] like Fig. 4 , Fig. 6 As shown in the embodiments of the present invention, the drone also includes other functional components, which will not be described in detail here.

[0056] In the drone of this embodiment, the power unit pressurizes or accelerates the air drawn in from outside the drone through the air inlet 120. The pressurized or accelerated air is then discharged from the drone through the exhaust port, generating thrust and thus driving the drone to move. The first solenoid valve 400 controls the opening and closing of the exhaust port, thereby controlling the direction and speed of the drone. The second solenoid valve 500 controls the opening and closing of the second air outlet 141, thereby accelerating the drone. The drone of this embodiment adopts a bladeless design, resulting in low noise, low wind resistance, and minimal impact on flight even in strong winds.

[0057] As mentioned above, although exemplary embodiments of the present invention have been described in the specification with reference to the accompanying drawings, the present invention is not limited to the specific embodiments described above, and the scope of protection of the present invention should be defined by the claims and their equivalents.
