Detailed implementation manners

[0031] The present invention will be further described in conjunction with the following embodiments.

[0032] As Figures 1 to 10 it can be known, an energy-saving heat exchanger described in this embodiment includes a housing 2; a blowing mechanism is provided at the top of the housing 2; the blowing mechanism includes a drive seat 3, a motor 31, a first linkage assembly and a fan seat 4; the drive seat 3 is provided at the top of the housing 2; the motor 31 is provided on the drive seat 3; a transmission shaft 32 is provided at the output end of the motor 31; the transmission shaft 32 is connected to the fan seat 4 through the first linkage assembly;

[0033] A plurality of fixed fan blades 51 are rotatably provided on the side wall of the fan seat 4 along the circumferential direction; the fixed fan blades 51 are telescopically provided with movable fan blades 52; the blowing mechanism further includes a second linkage assembly; the transmission shaft 32 drives the fixed fan blades 51 to rotate and drives the movable fan blades 52 to telescopically move through the second linkage assembly.

[0034] Specifically, for the energy-saving heat exchanger described in this embodiment, when the motor 31 in the drive seat 3 is started, the fan seat 4 is driven to rotate through the transmission shaft 32 and the first linkage assembly. When the fan seat 4 rotates, wind flow is generated through the fixed fan blades 51 and the movable fan blades 52; when it is necessary to change the air volume of the energy-saving heat exchanger, the motor 31 drives the movable fan blades 52 to telescopically move in the fixed fan blades 51 through the transmission shaft 32 and the second linkage assembly, so as to change the total fan blade area of the movable fan blades 52 and the fixed fan blades 51. At the same time, the motor 31 drives the fixed fan blades 51 and the movable fan blades 52 to flip by a certain angle through the transmission shaft 32 and the second linkage assembly, so as to change the air volume of the energy-saving heat exchanger by changing the total fan blade area of the movable fan blades 52 and the fixed fan blades 51 and the flipping angle of the movable fan blades 52 and the fixed fan blades 51.

[0035] An energy-saving heat exchanger according to this embodiment, the first linkage assembly includes an upper one-way gear 61, a lower one-way gear 62, a first bevel gear 63, a second bevel gear 64 and a gear ring 65; an upper bevel gear surface is provided on the outer periphery of the upper one-way gear 61; an upper bevel gear surface is provided on the outer periphery of the lower one-way gear 62; an inner bevel gear surface is provided on the inner wall of the gear ring 65; the upper one-way gear 61 and the lower one-way gear 62 are respectively connected to the transmission shaft 32; the upper bevel gear surface meshes with the top of the first bevel gear 63; the lower bevel gear surface meshes with the bottom of the first bevel gear 63; the first bevel gear 63 is connected to the second bevel gear 64; the second bevel gear 64 meshes with the inner bevel gear surface; the gear ring 65 is connected to the fan base 4.

[0036] Specifically, through the above settings, when the motor 31 rotates clockwise, the transmission shaft 32 is linked with the upper one-way gear 61, and the transmission shaft 32 slips with the lower one-way gear 62. At this time, the upper one-way gear 61 drives the first bevel gear 63 to rotate clockwise, and the first bevel gear 63 drives the fan base 4 to rotate clockwise through the second bevel gear 64 and the gear ring 65; when the motor 31 rotates counterclockwise, the transmission shaft 32 is linked with the lower one-way gear 62, and the transmission shaft 32 slips with the upper one-way gear 61. At this time, the lower one-way gear 62 drives the first bevel gear 63 to rotate clockwise, and the first bevel gear 63 drives the fan base 4 to rotate clockwise through the second bevel gear 64 and the gear ring 65.

[0037] In summary, through the above settings in this embodiment, no matter whether the motor 31 rotates clockwise or counterclockwise, the fan base 4 always rotates in the same direction, ensuring the continuity of the rotation of the fan base 4, and generating air flow by fixing the fan blade 51 and the movable fan blade 52.

[0038] An energy-saving heat exchanger according to this embodiment, the second linkage assembly includes a bracket 7 provided in the fan base 4, a change one-way gear 41 rotatably provided on the bracket 7, a driving gear 42 circumferentially provided outside the change one-way gear 41, and a rotating gear 43 connected to the driving gear 42; the driving gear 42 meshes with the outer circumference of the change one-way gear 41; the change one-way gear 41 is connected to the transmission shaft 32; the rotating gear 43 is used to drive the fixed fan blade 51 to rotate and drive the movable fan blade 52 to expand and contract. An energy-saving heat exchanger according to this embodiment, the second linkage assembly further includes a rotating fixed rod 81, a movable rod 82, and a connecting rod 83; one end of the fixed rod 81 is rotatably provided on the bracket 7; the other end of the fixed rod 81 is telescopically provided at one end of the movable rod 82; the other end of the movable rod 82 is connected to the movable fan blade 52 through the connecting rod 83; the fixed rod 81 and the movable rod 82 are connected by a profile; the movable rod 82 and the connecting rod 83 are connected by a profile; the movable fan blade 52 and the fixed fan blade 51 are connected by a profile. An energy-saving heat exchanger according to this embodiment, a torsion spring 84 is provided between the fixed rod 81 and the bracket 7; a return spring 85 is provided between the movable rod 82 and the fixed fan blade 51; a plurality of driving protrusions 86 are provided on the outer wall of the movable rod 82; the plurality of driving protrusions 86 are spirally distributed on the outer wall of the movable rod 82; the driving protrusion 86 abuts against the rotating gear 43.

[0039] Specifically, for the energy-saving heat exchanger according to this embodiment, when the motor 31 rotates clockwise, the transmission shaft 32 slips with the change one-way gear 41, and at this time, the movable fan blade 52 and the fixed fan blade 51 cannot be driven to work.

[0040] When it is necessary to change the total fan blade area of the movable fan blade 52 and the fixed fan blade 51 and the flipping angle of the movable fan blade 52 and the fixed fan blade 51, the motor 31 rotates counterclockwise, so that the transmission shaft 32 drives the change one-way gear 41 to rotate, and the change one-way gear 41 drives the rotating gear 43 to rotate through the driving gear 42. Due to the action of the torsion spring 84, the driving protrusion 86 abuts against the rotating gear 43. Therefore, when the rotating gear 43 rotates, the movable rod 82 moves axially and rotates at the same time. Therefore, the movable rod 82 drives the movable fan blade 52 to move, thereby changing the total fan blade area of the movable fan blade 52 and the fixed fan blade 51, and the movable rod 82 drives the movable fan blade 52 and the fixed fan blade 51 to rotate, thereby changing the rotation angle of the movable fan blade 52 and the fixed fan blade 51.

[0041] An energy-saving heat exchanger according to this embodiment, one end of the fixed rod 81 is provided with a swing arm 9; one end of the swing arm 9 is provided with a strip-shaped groove 91 along the length direction; a floating pin 92 is movably arranged in the strip-shaped groove 91; the floating pin 92 is telescopically arranged in the swing arm 9; a tension spring 93 is arranged between the floating pin 92 and the other end of the swing arm 9; the bracket 7 is provided with a guide groove; the floating pin 92 is movably arranged in the guide groove. An energy-saving heat exchanger according to this embodiment, the guide groove includes a first arc groove 71, a second arc groove 72 and a vertical groove 73; one end of the first arc groove 71 is communicated with the top of the vertical groove 73; one end of the second arc groove 72 is communicated with the bottom of the vertical groove 73; the other end of the first arc groove 71 is communicated with the other end of the second arc groove 72; the depth of the top of the vertical groove 73 is the same as the depth of the first arc groove 71; the depth of the bottom of the vertical groove 73 is the same as the depth of the second arc groove 72; the depth of the first arc groove 71 is greater than the depth of the second arc groove 72; an inclined surface 74 is arranged in the middle of the vertical groove 73. An energy-saving heat exchanger according to this embodiment, the inner wall of the second arc groove 72 is provided with a one-way pawl 75 that cooperates with the floating pin 92.

[0042] Specifically, through the above settings, when the floating pin 92 is located at the bottom of the vertical groove 73, the outermost driving protrusion 86 abuts against the rotating gear 43, and at this time, the movable fan blade 52 is completely retracted into the fixed fan blade 51; when it is necessary to change the total fan blade area of the movable fan blade 52 and the fixed fan blade 51 and the flipping angle of the movable fan blade 52 and the fixed fan blade 51, the driving motor 31 rotates counterclockwise, so that the transmission shaft 32 drives the conversion one-way gear 41 to rotate, and the conversion one-way gear 41 drives the rotating gear 43 to rotate through the driving gear 42. Due to the action of the torsion spring 84, the driving protrusion 86 abuts against the rotating gear 43. Therefore, when the rotating gear 43 rotates, the movable rod 82 moves axially and rotates at the same time. At this time, the floating pin 92 moves along the second arc groove 72. After the adjustment is completed, the motor 31 rotates clockwise again. Since the floating pin 92 is clamped with the one-way pawl 75 of the second arc groove 72, the position of the movable fan blade 52 and the rotation angle of the fixed fan blade 51 are fixed at this time.

[0043] When it is necessary to readjust the total blade area of the movable blade 52 and the fixed blade 51, as well as the flipping angles of the movable blade 52 and the fixed blade 51, it is only necessary to make the motor 31 rotate counterclockwise again until the innermost driving protrusion 86 abuts against the rotating gear 43. At this time, the protruding area of the movable blade 52 is the largest, and the rotation angle of the fixed blade 51 is the largest. At the same time, the floating pin 92 moves to the other end of the first arc-shaped groove 71; and when the innermost driving protrusion 86 moves to the position of the rotating gear 43, under the action of the torsion spring 84 and the return spring 85, the movable rod 82 is restored, and the movable blade 52 and the fixed blade 51 are reset at the same time. After passing through the first arc-shaped groove 71, the floating pin 92 moves back to the bottom of the vertical groove 73.

[0044] In an energy-saving heat exchanger described in this embodiment, a heating element 21 is provided at the bottom of the casing 2. Through the above setting, hot air can be provided to the runner assembly 11.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
