[0049] Embodiment 1, as shown in Figures 1-9 , discloses a multi-mode vortex air supply device, comprising:

[0050] The hollow sleeve 1 is internally annular, and is provided with first, second, third and fourth air holes 103, 104, 105 and 106, and the annular cavity is provided with an eccentric air control body 3, as shown in Figures 1-3 ;

[0052] The drive motor 5 has a transmission shaft passing through the mounting hole 101 on the hollow sleeve 1 and connected with the eccentric air control body 3, for driving the eccentric air control body 3 to rotate, thereby periodically compressing each gas storage cavity to generate vortex air flow; as shown in Figures 1-2 ;

[0053] Four wind controllers, divided into first wind controller 9, second wind controller 10, third wind controller 11, fourth wind controller 12, are sequentially distributed on the wind storage hollow sleeve 1 from inside to outside in the radial direction, the external support 109 is arranged on the wind storage hollow sleeve in the circumferential direction, the external support 109 is provided with 110, and the support spring 8 connected with the four wind controllers is sequentially arranged on the guide rail 110; each wind controller comprises an extrusion plate 901 and two position different linkage rods 903, the extrusion plate 901 is installed on the bearing plate 9 through the support spring 8, and the upper surface thereof is flush with the upper surface of the wind storage hollow sleeve 1, as shown in Figure 8 ;

[0054] The wedge-shaped extrusion block 7 is arranged in the accommodation groove 102 of the wind storage hollow sleeve 1 and is driven by the electric push rod 6 to move in the radial direction, and is used for selectively pressing down one extrusion plate 901 in the four wind controllers, as shown in Figure 7 ;

[0055] The sealing valve 2 comprises a sealing block 202 slidably arranged in the sealing groove 107, a linkage plate 203 slidably arranged in the sliding groove 108 and a reset spring 201, the lower end of the linkage rod 803 abuts against the upper surface of the linkage plate 203 when the extrusion plate 801 is pressed down, thereby driving the sealing block 202 to move downward to seal the specified combination of air holes, so as to switch the air supply mode, as shown in Figure 5 .

[0056] As shown in Figure 3 , the air holes comprise a first air hole 103, a second air hole 104, a third air hole 105 and a fourth air hole 106, the four air holes are respectively communicated with four air storage cavities, the third air hole 105 is provided with a sealing groove 107, and the second air hole 104 is provided with a sliding groove 108.

[0057] The four wind controllers each comprise an extrusion plate 901, a guide rail mounting hole 902 provided on the extrusion plate 901 and connected with the guide rail 110, and a linkage rod 903 arranged below the extrusion plate 901, the upper surface of the extrusion plate 901 is flush with the upper surface of the wind storage hollow sleeve 1, the lower end of the linkage rod 903 abuts against the upper surface of the linkage plate 203 when the extrusion plate 901 is pressed down, thereby driving the sealing block 202 to move downward to open and close different air holes.

[0058] The positions of the two linkage rods 903 arranged on the extrusion plate 901 at the bottom of the four wind controllers are different.

[0059] As shown in Figure 9 , the inner wall top of the wind storage hollow sleeve 1 is provided with a cover plate 14, and the cover plate 14 seals the eccentric wind controller body 3.

[0060] The working principle of the application is as shown in Figures 1-8 .

[0061] When the vortex air supply needs to be carried out, the transmission shaft of the driving motor 5 passes through the driving hole 101, and the transmission shaft of the driving motor 5 is arranged on the upper surface of the eccentric air control body 3, so that the driving motor 5 can drive the eccentric air control body 3 to rotate around the rotating shaft. Since the eccentric air control body 3 is arranged eccentrically in the inside of the air storage hollow sleeve 1, the distance between the outside of the eccentric air control body 3 and the inner wall of the air storage hollow sleeve 1 changes from small to large and then from large to small. Meanwhile, the inner wall of the air storage hollow sleeve 1 is divided into an air outlet arc surface 111 and an air inlet arc surface 112. When the adjacent two sealing plates 4 installed in the eccentric air control body 3 contact with the two arc surfaces, the volume of the cavity composed of the rotating air inlet arc surface 112 becomes larger and larger, and the volume of the cavity composed of the air outlet arc surface 111 becomes smaller and smaller.

[0062] When the eccentric air control body 3 rotates, the sealing plate 4 located in the installation groove 301 will be attached to the inner wall of the air storage hollow sleeve 1, so as to divide the internal space of the air storage hollow sleeve 1 into four air storage cavities, as shown in the figure. Figure 6 The first sealing plate 401, the second sealing plate 402 and the air inlet arc surface 112 form a first air storage cavity, the second sealing plate 402, the third sealing plate 403 and the air inlet arc surface 112 form a second air storage cavity, the third sealing plate 403, the fourth sealing plate 404 and the air outlet arc surface 111 form a third air storage cavity, and the fourth sealing plate 404, the fifth sealing plate 405 and the air outlet arc surface 111 form a fourth air storage cavity. The size relationship of the four cavity volumes is: the second air storage cavity > the first air storage cavity > the third air storage cavity > the fourth air storage cavity. Meanwhile, the first air hole 103, the second air hole 104, the third air hole 105 and the fourth air hole 106 are respectively communicated with the four air storage cavities, and the compensation spring 13 arranged on the sealing plate 4 is arranged in the spring receiving cavity 302, so that the outside of the sealing plate 4 can be attached to the inside of the air storage hollow sleeve 1 at all times when the eccentric air control body 3 rotates.

[0063] The output end of the electric push rod 6 can drive the wedge-shaped extrusion block 7 in the positioning slot 102 to move. Since the number of air controllers is four, they are arranged from inside to outside as the first air controller 9, the second air controller 10, the third air controller 11, and the fourth air controller 12. Taking the first air controller 9 as an example, the extrusion plate 901 of the air controller 9 is connected to the supporting spring 8 at the bottom, and the bearing plate 901 is provided with a guide rail mounting hole 902 and is nested on the guide rail 110 to prevent the air controller from tilting and rotating when the wedge-shaped extrusion block 7 is pressed, but only moving downward. The lower surface of the extrusion plate 901 is provided with two linkage rods 903, and the positions of the two linkage rods 903 at the bottom of the four air controllers on the extrusion plate 901 are different. The linkage rod of the first air controller 9 realizes the closing of the air holes 104 and 106, the linkage rod of the second air controller 10 realizes the closing of the air holes 103 and 106, the linkage rod of the third air controller 11 realizes the closing of the air holes 104 and 105, and the linkage rod of the fourth air controller 12 realizes the closing of the air holes 103 and 105.

[0064] Since the upper surfaces of the extrusion plates 901 of the air controllers are flush with the upper surface of the air storage hollow sleeve 1, when the electric push rod 6 drives the wedge-shaped extrusion block 7 to move, the wedge-shaped extrusion block 7 will extrude the extrusion plate 901 of the air controller 9 downward.

[0065] State one: when the wedge-shaped extrusion block 7 extrudes the extrusion plate 901 of the innermost first air controller 9 downward, the extrusion plate 901 will compress the supporting spring 8, and at the same time, drive the linkage rod 903 to move downward along the guide rail 110. Then, the lower end of the linkage rod 903 will contact the upper surface of the linkage plate 203, thereby moving the sealing block 202 provided on the linkage plate 203 downward, and also stretching the return spring 201. Since the linkage plate 203 and the sealing block 202 are respectively slidably arranged in the sliding groove 108 and the sealing groove 107, the linkage plate 203 and the sealing block 202 can be more stable when sliding. When the sealing block 202 moves downward, it will seal the second air hole 104 and the fourth air hole 106, so that air can only enter the first air storage cavity from the first air hole 103, and be blown out from the third air hole 105. Since the volume of the first air storage cavity entering from the first air hole 103 is small, when the eccentric air controller 3 drives the sealing plate 4 to extrude the airflow from the air storage cavity connected with the third air hole 105, it will cause poor vortex ring generation effect, and the air supply distance of the airflow is the shortest. This is the first air supply mode.

[0066] When the wedge-shaped extrusion block 7 continues to move, the second air controller 10 is extruded, and the first air controller 9 is no longer in contact. When the first air controller 9 is extruded, the supporting spring 8 is energized, so that the supporting spring 802 drives the first air controller 9 to reset, so that the second air hole 104 and the fourth air hole 106 are no longer sealed;

[0067] The second air controller 10 generates a second air supply mode, which is air inlet from the second air hole 104 and air outlet from the third air hole 105. The third air controller 11 generates a third air supply mode, which is air inlet from the first air hole 103 and air outlet from the fourth air hole 106. The fourth air controller 10 generates a fourth air supply mode, which is air inlet from the second air hole 104 and air outlet from the fourth air hole 106. Since the vortex ring generated by the fourth air supply mode has the best length-diameter ratio, the transmission distance of the vortex ring is the farthest in this mode. As the air flow generated by the vortex ring decreases, the stability of the vortex ring decreases, and the transmission distance also decreases. Therefore, the air flow size of a single vortex ring generated by the four modes and the air supply distance are: the fourth air supply mode > the third air supply mode > the second air supply mode > the first air supply mode.

[0068] Embodiment 2, as shown in Figure 10 The system comprises:

[0069] A temperature and humidity sensor for real-time collection of environmental temperature and humidity data;

[0070] A communication module for uploading the environmental temperature and humidity data to the control module;

[0071] A control module for receiving the environmental temperature and humidity data, logically judging according to the required air supply mode of the user, determining the corresponding working mode and the required driving parameters, and sending driving signals to the driving motor and the electric push rod respectively;

[0072] The driving motor responds to the instruction, and the transmission shaft drives the eccentric air controller to rotate in the air storage hollow sleeve. Through the cooperation of the eccentric structure and the sealing plate, the air flow in the air storage cavity is extruded to form a vortex ring;

[0073] The electric push rod moves the wedge-shaped extrusion block according to the instruction, extrudes the extrusion plate of the corresponding air controller according to the preset stroke, triggers the sealing valve action through the linkage rod, realizes the opening and closing combination of different air holes, and completes the switching of the four modes.

[0074] The temperature and humidity sensor collects the environmental temperature and humidity data in real time, and uploads the data to the control module through the communication module. At the same time, the user can select the required air supply mode (such as strong wind concentration, weak wind diffusion, etc.) through the customer terminal, and the instruction is transmitted to the control module through the communication module;

[0075] After the control module receives the environmental data and user instructions, it performs logical judgment to determine the corresponding working mode and required driving parameters (such as the moving distance of the electric push rod, the rotating speed of the driving motor, etc.), and sends precise driving signals to the driving motor and the electric push rod, respectively;

[0076] The driving motor responds to the instructions, and its transmission shaft drives the eccentric air control body to rotate in the hollow sleeve. Through the cooperation of the eccentric structure and the sealing plate, the airflow in the gas storage cavity is extruded to form a vortex ring.

[0077] The electric push rod moves the wedge-shaped extrusion block according to the instructions, extrudes the corresponding extrusion plate of the air control device according to the preset stroke, triggers the sealing valve action through the linkage rod, realizes the opening and closing combination of different air holes, and completes the switching of four modes (such as sealing the first and fourth air holes corresponding to state one, sealing the first and third air holes corresponding to state two, etc.).

[0078] During the operation of the device, the control module feeds back the current working mode and environmental temperature and humidity data to the customer terminal through the communication module for real-time viewing by the user. If in the automatic mode, the control module will dynamically adjust the driving parameters according to the changes in temperature and humidity, optimize the vortex ring quality and air supply effect, and ensure the comfort level.

[0079] The above is only the preferred embodiment of the present application. It should be noted that for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should also be considered within the scope of protection of the present application.
