Description

Technical Field

[0001] The present invention relates to an active static vortex ring generator, belonging to the technical field of air outlet of air conditioners. Background Art

[0002] Since the current generation of vortex rings is intermittent, generating airflows intermittently, the vortex ring device cannot carry more airflows. One of the factors limiting the air supply volume of the vortex ring lies in the pause time after the splint (airflow cutoff plate) closes the air supply duct. The main purpose of the pause is to make the airflows in the air supply duct static and improve the effect of the next vortex ring generation. Without the pause time, the generated vortex ring effect is very poor. In the existing truncated vortex ring device, the cutoff plate is arranged at the inlet of the air supply duct. When the cutoff plate closes the flow channel, the outlet of the air supply duct is connected to the outside, forming a semi-closed environment, resulting in a relatively long static time required for the airflows in the duct. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an active static vortex ring generator to solve the problem of the relatively long static time required for the airflows in the duct of the existing truncated vortex ring device; To achieve the above purpose / To solve the above technical problems, the present invention is implemented by the following technical solutions: An active static vortex ring generator, comprising: A main duct, on the top of which an axial flow fan is provided, and on the bottom of which a frame is provided; An intake duct, which is evenly spaced on the corresponding intake duct mounting holes on the frame; on one side of the intake duct, there is an active static cavity, and on the other side, there is a diversion cavity, and a gas guide pipe is provided in the diversion cavity; A cutoff disk, on which arc-shaped openings are provided corresponding to the positions of the intake ducts; A driving device, which is installed in the corresponding motor rotating shaft mounting holes on the frame through bearings and is connected to the cutoff disk at the same time, providing rotational power for the cutoff disk, and opening or closing the intake duct by rotating the cutoff disk.

[0004] Optionally, a diversion plate is provided in the active static cavity. The bottom of the diversion plate is connected to an active deceleration pipe through a flexible hose. On one side of the inner wall of the active static cavity, a rotary opening and closing valve is connected through a telescopic rotating shaft. An active static air hole communicating with the intake duct is opened at the lower part. The active deceleration pipe is connected to the active static air hole, and the two ends of the bottom of the rotary opening and closing valve are rotatably connected to the active static cavity.

[0005] Optionally, the active deceleration tube is hinged to the inner wall of the active static chamber, and one end close to the active static air hole is connected to the active static chamber through a return spring, so that the air inlet of the active deceleration tube has a position flush with the active static air hole and a position capable of making the air outlet of the active deceleration tube flush with the active static air hole.

[0006] Optionally, both ends of the top of the rotary opening and closing valve are provided with telescopic grooves, telescopic limiting rods are arranged in the telescopic grooves, and grooves are arranged at positions corresponding to the telescopic limiting rods on the upper part of one side of the inner wall of the active static chamber.

[0007] Optionally, the telescopic limiting rod includes a wedge-shaped telescopic block configured with the groove, and the wedge-shaped telescopic block is provided with a first energy storage spring.

[0008] Optionally, both ends of the bottom of the rotary opening and closing valve are provided with shaft installation holes and second energy storage springs, and shafts are arranged at positions corresponding to the shaft installation holes in the active static chamber.

[0009] Optionally, the side of the rotary opening and closing valve close to the active static chamber is a first stress surface, and the other side is provided with a second stress surface.

[0010] Optionally, a first telescopic valve is arranged on the upper part of the inner wall of the diversion chamber close to the intake pipe, the first telescopic valve is connected to a second telescopic valve, the first telescopic valve and the second telescopic valve are wrapped with an elastic membrane, and the second telescopic valve can retract into the first telescopic valve.

[0011] Optionally, sliding grooves are arranged at positions corresponding to both ends of the first telescopic valve and the second telescopic valve in the diversion chamber.

[0012] Optionally, a first inclined surface air guide plate and a second inclined surface air guide plate are arranged at the top of the first telescopic valve and the second telescopic valve, and the length of the first inclined surface air guide plate is greater than the length of the second inclined surface air guide plate.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: When the cutoff disc closes the intake pipe in the present invention, the high-speed fluid opens the rotary opening and closing valve. At this time, the air flow impacts the guide plate and presses the guide plate downward, thereby causing the active deceleration tube to rotate and extend out of the active static air hole. At this time, the fluid passes through the active deceleration tube and jets decelerated air flow in the direction close to the rotary motor. Then, the upward moving decelerated air flow collides with the downward moving air flow in the pipe, thereby consuming the energy of the fluid in the pipe and enabling it to be quickly static. Furthermore, the static time of the air flow in the air supply pipe can be greatly shortened, and the total air supply volume per unit time of the device can be increased; When the cut-off disc of the present invention does not fully open and close the intake pipe, due to the small intake area, non-uniform high-speed airflows will be generated. By guiding the high-speed airflows generated during opening into two air guide pipes and then discharging them outside the pipe, the impact on the uniformity of the intake pipe is reduced. At the same time, the high-speed airflows generated during closing are guided into the active deceleration pipe. After their reverse movement, they collide with the fluid in the pipe, further reducing the impact on the uniformity of the intake pipe. Description of the Drawings

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0018] As Figures 1-11 shown, an active static vortex ring generator is disclosed, including: Main pipeline 2, with an axial flow fan 1 provided at the top of the main pipeline 2 and a frame 4 provided at the bottom; Intake pipeline 8, which is evenly spaced on the corresponding intake pipeline mounting holes 401 on the frame 4; wherein one side of the intake pipeline 8 is provided with an active static chamber 801, and the other side is provided with a diversion chamber 802, and the diversion chamber 802 is provided with an air guide pipe; wherein the air guide pipe includes a first air guide pipe 5 and a second air guide pipe 6; Cut-off disc 3, with an arc-shaped opening provided at the position corresponding to the intake pipeline 8; The driving device is installed in the corresponding motor shaft mounting hole 402 on the frame 4 through bearings, and is connected to the cutting disc 3 at the same time, providing rotational power for the cutting disc 3, and opening or closing the intake pipe 8 by rotating the cutting disc 3.

[0019] In the specific implementation process of this embodiment, four intake pipes 8 are arranged at equal intervals in the circumferential direction on the frame 4, and the number of arc-shaped openings is the same as that of the intake pipes 8, and the positions correspond to the intake pipes 8 one by one. The driving device adopts a rotary motor 7.

[0020] As Figures 2-3 shown, in the specific implementation process of this embodiment, a flow guide plate 15 is provided in the active static chamber 801. The bottom of the flow guide plate 15 is connected to an active deceleration pipe 16 through a flexible hose (not shown in the figure). One side of the upper part of the inner wall of the active static chamber 801 is connected to a rotary opening and closing valve 11 through a telescopic rotating shaft 807. An active static air hole 808 communicating with the inside of the intake pipe 8 is opened at the lower part. The active deceleration pipe 16 is connected to the active static air hole 808. The two ends of the bottom of the rotary opening and closing valve 11 are rotatably connected to the active static chamber 801. When the rotary opening and closing valve 11 is opened, air enters the flow guide plate 15.

[0021] In this embodiment, the connection method and relationship between the bottom of the rotary opening and closing valve 11 and the intake pipe 8 are further elaborated. The two ends of the bottom of the rotary opening and closing valve 11 are provided with a shaft mounting hole 1103 and a second energy storage spring 14. A rotating shaft (schematic in the figure) is provided at the position of the active static chamber 801 corresponding to the shaft mounting hole 1103. The rotating shaft is inserted into the shaft mounting hole 1103. The second energy storage spring 14 is used to provide a force for automatic reset after the rotary opening and closing valve 11 is opened.

[0022] In the specific implementation process of this embodiment, the active deceleration pipe 16 is hinged to the inner wall of the active static chamber 801, and one end close to the active static air hole 808 is connected to the active static chamber 801 through a return spring 17, so that the air inlet of the active deceleration pipe 16 has a position flush with the active static air hole 808 and can make the air outlet of the active deceleration pipe 16 flush with the active static air hole 808.

[0023] Here, the two positions are further described. The air inlet of the active deceleration pipe 16 has a position flush with the active static air hole 808. After the flow guide plate 15 is pressed by the air flow, the flexible hose is further pressed down, and the active deceleration pipe 16 is further pressed down, and the active deceleration pipe 16 is passed from the active static air hole 808 into the intake pipe 8. At this time, the active deceleration pipe 16 enters the intake pipe 8, and the air inlet is flush with the active static air hole 808. When the air flow pressure gradually decreases, affected by the return spring 17, the active deceleration pipe 16 resets to Figure 2 state.

[0024] like Figure 2 and Figure 3 As shown, telescopic grooves 1104 are provided at both ends of the top of the rotary opening and closing valve 11, and a telescopic limit rod is provided in the telescopic groove 1104. A groove 806 is provided at the position corresponding to the telescopic limit rod on the upper part of one side of the inner wall of the active static chamber 801, and the telescopic limit rod includes a wedge-shaped telescopic block 12 equipped with the groove 806, and the wedge-shaped telescopic block 12 is equipped with a No. 1 force storage spring 13. When the wedge-shaped telescopic block 12 is squeezed inward, it is separated from the groove 806 and the rotary opening and closing valve 11 is rotated along the telescopic shaft 807, and the upper part of the rotary opening and closing valve 11 is opened. When the airflow pressure gradually decreases, when the wedge-shaped telescopic block 12 returns to the groove 806, the elastic force of the No. 1 force storage spring 13 is received to insert the wedge-shaped telescopic block 12 into the groove 806.

[0025] like Figure 4 As shown, one side of the rotary opening and closing valve 11 close to the active static chamber 801 is a force-bearing surface 1101 , and the other side is provided with a force-bearing surface 2 1102 .

[0026] like Figure 5 As shown, the guide cavity 802 is provided with a No. 1 telescopic valve 9 on the upper part of the inner wall near the air intake pipe 8, and the No. 1 telescopic valve 9 is connected to the No. 2 telescopic valve 10. The outer sides of the No. 1 telescopic valve 9 and the No. 2 telescopic valve 10 are wrapped with elastic membranes, and the No. 2 telescopic valve 10 can be retracted into the No. 1 telescopic valve 9. The tops of the No. 1 telescopic valve 9 and the No. 2 telescopic valve 10 are provided with a No. 1 inclined air guide plate 901 and a No. 2 inclined air guide plate 1001. The length of the No. 1 inclined air guide plate 901 is greater than the length of the No. 2 inclined air guide plate 1001, wherein the No. 1 inclined air guide plate 901 is full-length, and the No. 2 inclined air guide plate 1001 is only a part, to prevent it from getting stuck and unable to retract. The guide cavity 802 is provided with sliding grooves 805 at the positions at both ends of the No. 1 telescopic valve 9 and the No. 2 telescopic valve 10.

[0027] When the cut-off disk of the present invention closes the air intake pipe, the high-speed fluid opens the rotary opening and closing valve. At this time, the airflow impacts the guide plate and presses the guide plate downward, thereby causing the active deceleration tube to rotate and extend the active static air hole. At this time, the fluid passes through the active deceleration tube to spray the deceleration airflow in the direction close to the rotating motor, thereby causing the upward-moving deceleration airflow to collide with the downward-moving airflow in the pipe, thereby consuming the energy of the fluid in the pipe and allowing it to quickly stop. In this way, the static time of the airflow in the air supply pipe can be greatly shortened, thereby increasing the total air supply volume per unit time of the device.

[0028] Working principle of the present invention: Reference Figure 1 and Figure 11As shown, in the initial state, the axial flow fan 1 is not turned on. A part of the second telescopic valve 10 is inserted into the first telescopic valve 9, and they can slide relative to each other. A layer of elastic membrane (not marked in the figure) is wrapped around the outer sides of the second telescopic valve 10 and the first telescopic valve 9, which can provide power for the rebound of the two valves. At the same time, it can seal the gap generated when the two valves are opened outwards. At this time, the three of them jointly close the diversion cavity 802 to prevent air leakage. Since there is no additional force at this time, the return spring 17 installed in the active static cavity 801 makes the active deceleration pipe 16 leave only a small outlet on the active static air hole 808. At the same time, because the diversion plate 15 and the active deceleration pipe 16 are connected by a flexible hose with a certain hardness (not marked in the figure), the diversion plate 15 is lifted by a certain distance under the action of the flexible hose. The wedge-shaped telescopic block 12 installed in the telescopic groove 1104 on the side of the rotary opening and closing valve 11 is located in the groove 806 at the entrance of the active static cavity 801 of the intake pipe 8 at this time, so that the rotary opening and closing valve 11 closes the active static cavity 801. The rotary motor 7 is installed in the motor shaft installation hole 402 through a bearing (not marked in the figure), and is connected to the cut-off disc 3 at the same time, providing rotational power for the cut-off disc 3. At this time, the four arc-shaped air inlets of the cut-off disc 3 do not coincide with the intake pipe 8, and all four intake pipes 8 are closed.

[0029] As Figure 8 shown, when the device is turned on, the axial flow fan 1 rotates, pumping the external air flow into the main pipe 2. At the same time, the rotary motor 7 is turned on to drive the cut-off disc 3 to rotate. When the arc-shaped opening of the cut-off disc 3 gradually coincides with the intake pipe 8, a gap will be opened first. At this time, the air flow can only enter from this gap, so high-speed air flow will be generated. Since the inclined air guide plates are provided at the tops of the second telescopic valve 10 and the first telescopic valve 9, the air flow is guided into the diversion cavity 802, and the air flow gives a lateral thrust to the second telescopic valve 10 and the first telescopic valve 9, making them move along the sliding groove 805 in the direction away from the first air guide pipe 5. Furthermore, within a certain limit when the cut-off disc 3 rotates to open the intake pipe 8, all the air flow enters the diversion cavity 802 and is discharged out of the device through the first air guide pipe 5 and the second air guide pipe 6.

[0030] As Figure 7 shown, when the second telescopic valve 10 and the first telescopic valve 9 are opened to the maximum limit, they can no longer follow the movement of the cut-off disc 3. At the same time, the elastic membrane accumulates a certain amount of elastic force. As the overlapping area of the arc-shaped opening of the cut-off disc 3 and the intake pipe 8 increases, the air flow velocity decreases and can no longer offset the elastic force of the elastic membrane. Therefore, at the next moment, the second telescopic valve 10 and the first telescopic valve 9 are quickly retracted along the sliding groove 805 under the drive of the elastic membrane, closing the diversion cavity 802, so that the air flow flows out from the intake pipe 8.

[0031] AsFigure 10 As shown, when the cutoff disc 3 starts to gradually close the intake pipe 8, as the overlapping area decreases, the flow velocity in the intake pipe 8 gradually increases. Therefore, the pressure exerted by the airflow on the force-receiving surface two 1102 also increases accordingly. At the same time, the wedge-shaped expansion block 12 is slowly pushed, and the first energy storage spring 13 installed between the wedge-shaped expansion block 12 and the expansion slot 1104 is compressed. When the opening area of the intake pipe 8 decreases to a certain critical value, that is, when the driving force of the airflow on the rotary opening and closing valve 11 causes the wedge-shaped expansion block 12 to completely contract from the groove 806, at the next moment, the rotary opening and closing valve 11 rotates around the expansion rotating shaft 807 to open, so that the force-receiving surface one 1101 faces the airflow. Since the area of the force-receiving surface one 1101 is larger than the area of the force-receiving surface two 1102, the driving force of the airflow on the rotary opening and closing valve 11 is further enhanced at this time, driving the rotary opening and closing valve 11 to rotate around the expansion rotating shaft 807 to the maximum area, and at the same time compressing the second energy storage spring 14. Subsequently, the airflow enters the guide plate 15, generating a downward pressure on it, thereby causing the active deceleration pipe 16 to rotate around the expansion rotating shaft 807, and the outlet position of the reset spring 17 extends into the intake pipe 8, and the direction is opposite to the airflow in the pipe. At the next moment, the airflow introduced into the active static chamber 801 flows out from the active deceleration pipe 16 and collides with the airflow in the intake pipe 8, losing the energy and momentum of the airflow in the pipe, so that after the cutoff disc completely closes the intake pipe 8, the static time required for the airflow in the intake pipe 8 is reduced, and the generation frequency of the vortex ring per unit time is increased.

[0032] As Figure 9 As shown, after the cutoff disc completely closes the intake pipe 8, the reset spring 17 and the second energy storage spring 14 release energy, causing the active deceleration pipe 16 to contract, and at the same time the rotary opening and closing valve 11 resets to close the active static chamber 801.

[0033] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
