Detailed implementation manners

[0032] To make the purpose, technical solutions and advantages of the present application clearer, the following will describe the technical solutions of the present utility model in detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application.

[0033] Currently, for those that can achieve air supply in two directions, two motors and two lead screws can also be used, with each motor driving one lead screw respectively, but the two motors greatly increase the overall cost of the machine.

[0034] Therefore, in order to achieve reference Figure 1 , the embodiment of the present utility model provides an air supply structure, including: a first lead screw 4, a second lead screw 5, and a motor 19;

[0035] A wind guiding mechanism 1 for air supply is respectively arranged on the first lead screw 4 and the second lead screw 5;

[0036] As a preferred implementation manner of the embodiment of the present utility model, as Figure 2 shown, the air guiding mechanism 1 includes: an air guiding plate 6, a gear 7 and a toothed plate 8; the air guiding plate 6 is fixedly arranged on the gear 7, the gear 7 is connected with the toothed plate 8; the toothed plate 8 is connected with the first lead screw 4 or the second lead screw 5.

[0037] The embodiment of the utility model does not limit the connection manner between the air guiding plate 6 and the gear 7, and the connection manner between the gear 7 and the toothed plate 8.

[0038] Exemplarily, the air guiding plate 6 is fixedly connected with the gear 7. The connection between the gear 7 and the toothed plate 8 is: a meshing groove that can mesh with the gear 7 is arranged on the surface of the toothed plate 8, and the gear 7 is meshingly connected with the meshing groove on the surface of the toothed plate 8.

[0039] It should be noted that the embodiment of the present utility model does not limit the connection manner between the toothed plate 8 of the air guiding mechanism 1 and the first lead screw 4 and the second lead screw 5, and those skilled in the art can adopt specific connection manners according to needs.

[0040] In one embodiment, the toothed plate 8 of the air guiding mechanism 1 is threadedly connected with the first lead screw 4 and the second lead screw 5 respectively through a lead screw nut 9.

[0041] In another embodiment, the toothed plate 8 of the air guiding mechanism 1 is connected with the first lead screw 4 and the second lead screw 5 respectively through flanges, or the toothed plate 8 of the air guiding mechanism 1 is connected with the first lead screw 4 and the second lead screw 5 respectively through welding.

[0042] In addition, the principle and process of the air guiding mechanism 1 for guiding air are prior art, and the present utility model will not elaborate herein.

[0043] The motor 19 drives the second lead screw 5 to rotate through a motor shaft;

[0044] In one embodiment, as Figure 1 shown in, the motor 19 drives the second lead screw 5 to rotate through a motor shaft, including:

[0045] The second lead screw 5 is provided with a first belt pulley 16, the motor shaft is provided with a second belt pulley 18, and the first belt pulley 16 and the second belt pulley 18 are connected by a belt. In this way, when the motor 19 rotates, the motor shaft drives the second belt pulley 18 to rotate, the second belt pulley 18 drives the first belt pulley 16 to rotate through the belt. Since the first belt pulley 16 is fixed on the second lead screw 5, when the first belt pulley 16 rotates, the second lead screw 5 rotates, and the rotation direction of the second lead screw 5 is the same as the rotation direction of the motor shaft.

[0046] In another embodiment, a first transmission gear is provided on the motor shaft, a second transmission gear is provided on the second lead screw 5, and a third transmission gear is additionally provided between the two transmission gears. The first transmission gear meshes with the third transmission gear, and the third transmission gear meshes with the second transmission gear. When the motor 19 rotates, the motor shaft drives the first transmission gear to rotate in the same direction. The first transmission gear drives the third transmission gear to rotate in the opposite direction, and the third transmission gear then drives the second transmission gear to rotate in the same direction. Finally, the second transmission gear drives the second lead screw 5 to rotate, and the rotation direction of the second lead screw 5 is the same as the rotation direction of the motor 19.

[0047] The first lead screw 4 is provided with a first gear 13, and the motor shaft of the motor 19 is provided with a second gear 17. The first gear 13 is in transmission connection with the second gear 17. When the first gear 13 is in transmission connection with the second gear 17, while the second gear 17 rotates, the first gear 13 rotates in the opposite direction.

[0048] As a preferred implementation manner of the embodiment of the present utility model, the transmission connection between the first gear 13 and the second gear 17 includes:

[0049] The first gear 13 and the second gear 17 mesh. In this way, the rotation directions of the first gear 13 and the second gear 17 are opposite. Since both the second gear 17 and the second lead screw 5 are driven by the motor shaft of the motor 19, and the first gear 13 can drive the first lead screw 4 to synchronously transmit power, when the first gear 13 and the second gear 17 are in transmission connection, the rotation directions of the first lead screw 4 and the second lead screw 5 are opposite.

[0050] As another alternative implementation manner of the embodiment of the present utility model, it further includes a third gear and a fourth gear;

[0051] The first gear 13 meshes with the third gear, the third gear meshes with the fourth gear, and then the fourth gear meshes with the second gear 17. Through the third gear and the fourth gear, the effect that the rotation directions of the first gear 13 and the second gear 17 are opposite can be generally achieved, and further the purpose that the rotation directions of the first lead screw 4 and the second lead screw 5 are opposite when the first gear 13 and the second gear 17 are in transmission connection can be achieved.

[0052] As a preferred implementation manner of the embodiment of the present utility model, the first gear 13 and the second gear 17 are bevel gears. It should be noted that the first gear 13 and the second gear 17 can also be spur gears. However, when the first lead screw 4 moves towards the second lead screw 5 to form a same-direction rotation (which will be introduced in detail below) and then separates again, it is not easy for the spur gears to re-mesh. Therefore, in order to facilitate re-meshing, there are also certain requirements for the setting directions of the first gear 13 and the second gear 17.

[0053] Preferably, in order to be similar to the existing air supply, as Figure 1 shown, the first lead screw 4 and the second lead screw 5 are located on the same straight line. It is equivalent to dividing a traditional single lead screw into two halves. In this way, when the first lead screw 4 moves and merges with the second lead screw 5 to form a single lead screw, it is the same as the traditional air supply structure.

[0054] The first lead screw 4 moves towards the second lead screw 5 to form a co-rotating motion, or the implementation structure for the first lead screw 4 to move and merge with the second lead screw 5 into a single lead screw is as follows:

[0055] One end of the first lead screw 4 close to the second lead screw 5 is provided with a first mating part, and one end of the second lead screw 5 close to the first lead screw 4 is provided with a second mating part;

[0056] When the first gear 13 is in transmission connection with the second gear 17, the first mating part and the second mating part are not connected;

[0057] When the first mating part and the second mating part are connected, the first gear 13 and the second gear 17 are not in transmission connection. When the first mating part and the second mating part are connected, the first lead screw 4 and the second lead screw 5 rotate in the same direction.

[0058] Preferably, the first mating part is arranged on the first gear 13.

[0059] In one embodiment, the first mating part is a plug, and the second mating part is a socket.

[0060] In another embodiment, the first mating part is a socket, and the second mating part is a plug.

[0061] Among them, the plug can be a small gear 14, and the socket is a mating tooth groove 15. The plug can also be a plug with an edge, and the socket is a socket adapted to the plug with an edge.

[0062] Among them, the movement of the first lead screw 4 depends on a movement structure. The movement structure is connected to the first lead screw 4 and is used to move the first mating part of the first lead screw 4 to be connected with the second mating part of the second lead screw 5, and / or is used to move the first gear 13 to be in transmission connection with the second gear 17.

[0063] Exemplarily, as Figure 1As shown in the figure, an inner sliding groove 10 is provided inside the first lead screw 4, and an air pump is connected inside the inner sliding groove 10. A piston plate 11 is slidably arranged inside the inner sliding groove 10. The piston plate 11 is fixedly connected to the first gear 13 through a hexagonal connecting rod 12. The air pump blows air, and the piston plate 11 is pushed through the inner sliding groove 10 of the first lead screw 4, thereby indirectly driving the hexagonal connecting rod 12 to extend and push the first gear 13, so that the first gear 13 is disengaged from the second gear 17, and the small gear 14 is pushed into the docking tooth groove 15 inside the first belt pulley 16. At this time, the first lead screw 4 and the second lead screw 5 move synchronously and blow air in the same direction.

[0064] The air supply structure provided by the embodiment of the present invention includes a first lead screw, a second lead screw and a motor. The first lead screw and the second lead screw are respectively provided with a wind guiding mechanism for air supply. The motor drives the second lead screw to rotate through the motor shaft. In addition, the motor is in transmission connection with the first gear of the first lead screw through the second gear on the motor shaft. When the first gear and the second gear are in transmission connection, while the second gear rotates, the first gear rotates in the opposite direction. Since both the second gear and the second lead screw are driven by the motor shaft of the motor, and the first gear can drive the first lead screw to synchronously transmit power, when the first gear and the second gear are in transmission connection, the rotation directions of the first lead screw and the second lead screw are opposite, and one motor can be used to drive two lead screws to realize air supply in two different directions, meeting the requirements of air supply in different directions.

[0065] It should be noted that for the air supply structure in the above embodiment, its main purpose is to make the second lead screw rotate in the same direction as the motor, while the first lead screw rotates in the opposite direction to the motor. In actual use, those skilled in the art can make the second lead screw rotate in the opposite direction to the motor, while the first lead screw rotates in the same direction as the motor, and the effect of separate flow and diversion can also be achieved.

[0066] Exemplarily, a transmission gear is used to replace Figure 1 the belt pulley in, that is, two transmission gears respectively replace the first belt pulley and the second belt pulley. In this way, the way that the motor drives the second lead screw to rotate through the motor shaft changes from belt transmission to gear transmission, and the rotation direction of the second lead screw is opposite to the rotation direction of the motor at this time.

[0067] The realization that the first lead screw rotates in the same direction as the motor can be achieved by adding a reversing gear between the first gear and the second gear on the basis of Figure 1 . That is, the first gear meshes with the reversing gear, and the reversing gear meshes with the second gear, so that the first gear and the second gear change from Figure 1 the reverse rotation in to the same direction rotation, and further makes the motor and the first lead screw communicate and rotate. And other structures are the same as Figure 1 and no improvement is made.

[0068] Based on the same concept, the embodiment of the present invention also provides an air supply device, including: the air supply structure provided in the above embodiment.

[0069] Among them, the air supply equipment includes but is not limited to air conditioners, purifiers, and humidifiers.
