[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] As introduced in the background technology, in order to solve the deficiencies in the existing technology, the present application proposes an energy-saving combined split air-conditioning unit with a pre-purification structure.

[0044] Example 1:

[0045] See also Figure 1 - Figure 11 An energy-saving combined split air-conditioning unit with a pre-purification structure includes an air-conditioning unit body 1, an air inlet 2 is provided on the side of the air-conditioning unit body 1, a purification channel 3 is connected to the outside of the air inlet 2, a filter mechanism 5 is slidably installed inside the purification channel 3, a driving mechanism 4 is installed inside the filter mechanism 5, and an adjustment mechanism 6 is installed on the top of the filter mechanism 5;

[0046] A chute is provided at the bottom of the purification channel 3. The outside of the purification channel 3 is connected to other mechanisms of the air conditioning unit. The filter mechanism 5 is slidably installed in the chute inside the purification channel 3. The outside of the drive mechanism 4 is transmission-connected to the filter mechanism 5. The outside of the drive mechanism 4 is connected to the inner wall of the air conditioning unit body 1.

[0047] The air inlet 2 can guide the air into the purification channel 3 inside the main body 1 of the air-conditioning unit. The filter mechanism 5 inside the purification channel 3 can filter the air passing through the purification channel 3. The driving mechanism 4 can drive the filter mechanism 5 to move inside the purification channel 3. When moving, the filter mechanism 5 can drive the driving mechanism 4 and the adjusting mechanism 6 to move synchronously. When moving inside the purification channel 3, the adjusting mechanism 6 can adjust the size of the filter holes on the filter mechanism 5. The driving mechanism 4 can also drive the filter mechanism 5 to move.

[0048] When working, external air enters the purification channel 3 inside the main body 1 of the air-conditioning unit from the air inlet 2, and the filter mechanism 5 can purify and filter the main impurities in the air. After passing through the purification and filtration of the filter mechanism 5, the air enters other mechanisms along the purification channel 3. When the filter mechanism 5 purifies and filters the air, the driving mechanism 4 can drive the filter mechanism 5 to move inside the purification channel 3, and the movement of the filter mechanism 5 inside the purification channel 3 can drive the adjustment mechanism 6 to move synchronously. When the adjustment mechanism 6 moves in the inclined section inside the purification channel 3, the size of the filter holes on the filter mechanism 5 can be adjusted. The movement of the adjustment mechanism 6 to adjust the size of the filter holes on the filter mechanism 5 can make the filter mechanism 5 more adaptable to the changes of impurities in the external air to adjust to the appropriate filter aperture size. After working for a period of time, the filter mechanism 5 can also be driven by the driving mechanism 4 to move and clean the impurities on the filter mechanism 5 to prevent the filter mechanism 5 from being clogged and affecting the purification and filtration effect by purifying and filtering the air for a long time.

[0049] Example 2:

[0050] The difference from the above embodiment is that, please refer to Figure 1 - Figure 11 The filtering mechanism 5 includes a filter storage cylinder 51 and a bottom sliding seat 53. The filter storage cylinder 51 is installed on the adjustment mechanism 6. The bottom sliding seat 53 is slidably installed inside the purification channel 3. A purification filter 52 is installed inside the filter storage cylinder 51. A filter collection reel 54 is rotatably installed inside the bottom sliding seat 53. A reel roller 55 is installed outside the filter collection reel 54. A transmission belt 56 is installed outside the reel roller 55.

[0051] The outside of the filter collection reel 54 is connected to the drive mechanism 4 through the reel roller 55 and the transmission belt 56. The drive mechanism 4 can drive the filter collection reel 54 to rotate inside the bottom sliding seat 53.

[0052] The driving mechanism 4 can drive the bottom sliding seat 53 to slide inside the purification channel 3 by being connected to the inner wall of the air-conditioning unit body 1 . When the bottom sliding seat 53 moves inside the purification channel 3 , it can drive the adjustment mechanism 6 to move synchronously.

[0053] One end of the purification filter 52 is wound around the inside of the filter storage cylinder 51, and the other end of the purification filter 52 is wound around the outside of the filter collection reel 54, so that the outside of the purification filter 52 is in contact with the outside of the adjustment mechanism 6;

[0054] The driving mechanism 4 drives the filter collection reel 54 to rotate, which can drive the purification filter 52 inside the filter storage cylinder 51 to move downward. When the driving mechanism 4 rotates, the purification filter 52 can be wound around the outside of the filter collection reel 54. When the purification filter 52 moves downward, the used purification filter 52 can be wound around the outside of the filter collection reel 54. When the purification filter 52 moves downward, the clean purification filter 52 inside the filter storage cylinder 51 can be covered on the outside of the adjustment mechanism 6.

[0055] During operation, the purification filter 52 can filter impurities in the air, and the outer portion of the purification filter 52 is in contact with the outer portion of the adjustment mechanism 6 during filtering. When the position of the adjustment mechanism 6 changes, the size of the filter holes on the purification filter 52 can be adjusted. After a period of filtering, the filter collection reel 54 can be driven by the driving mechanism 4 to rotate. When the filter collection reel 54 rotates, the purification filter 52 can be driven downward. When the purification filter 52 moves downward, the purification filter 52 can move the clean purification filter 52 inside the filter storage cylinder 51 downward to cover the outer portion of the adjustment mechanism 6. When the filter collection reel 54 rotates, the used purification filter 52 can be reeled onto the outer portion of the filter collection reel 54. The reeling mechanism of the filter collection reel 54 can timely replace and recycle the purification filter 52 in use, thereby ensuring the filtration efficiency of the purification filter 52 on the air. Reeling in the used purification filter 52 can effectively prevent dust and other impurities outside the purification filter 52 from spreading inside the purification channel 3.

[0056] Example 3:

[0057] The difference from the above embodiment is that, please refer to Figure 1 - Figure 11 The adjustment mechanism 6 includes a bottom mounting seat 61, which is mounted on the top of the bottom sliding seat 53. An elastic connecting rod 62 is mounted on the top of the bottom mounting seat 61. The movable end of the elastic connecting rod 62 is connected to the upper mounting seat 63. The filter storage cylinder 51 is mounted inside the upper mounting seat 63. The bottom of the upper mounting seat 63 is connected to a filter hole adjustment plate 64.

[0058] When the driving mechanism 4 drives the bottom sliding seat 53 to move inside the purification channel 3 , it can drive the bottom mounting seat 61 to move inside the purification channel 3 synchronously.

[0059] The bottom mounting seat 61 and the upper mounting seat 63 are connected by an elastic connecting rod 62. The upper mounting seat 63 is installed at the connection between the inclined section and the horizontal section of the purification channel 3;

[0060] When the upper mounting seat 63 moves along the inclined section inside the purification channel 3, the upper mounting seat 63 can move up and down on the bottom mounting seat 61 through the elastic connecting rod 62. When the upper mounting seat 63 moves up and down on the bottom mounting seat 61, it can drive the filter hole adjustment plate 64 to move up and down synchronously.

[0061] The purification filter 52 covers the outside of the filter hole adjustment plate 64. When the purification filter 52 moves up and down, it moves up and down along the outside of the filter hole adjustment plate 64. The filter holes on the filter hole adjustment plate 64 and the purification filter 52 are both inclined structures.

[0062] The upper mounting seat 63 can adjust the position of the filter holes on the filter hole adjustment plate 64 when driving the filter hole adjustment plate 64 to move up and down. The greater the position deviation between the filter holes on the filter hole adjustment plate 64 and the filter holes on the purification filter 52, the smaller the filter holes formed by the filter hole adjustment plate 64 and the purification filter 52. The smaller the position deviation between the filter holes on the filter hole adjustment plate 64 and the filter holes on the purification filter 52, the larger the filter holes formed by the filter hole adjustment plate 64 and the purification filter 52.

[0063] When the bottom sliding seat 53 drives the bottom mounting seat 61 to move toward the wider side of the purification channel 3, the elastic connecting rod 62 rebounds and drives the upper mounting seat 63 to move upward. When the upper mounting seat 63 moves upward, it can drive the filter hole adjustment plate 64 to move upward. During the upward movement of the upper mounting seat 63, it can also drive the filter storage cylinder 51 to move up and down synchronously, and when the upper mounting seat 63 moves up and down, the filter storage cylinder 51 can be driven to move up and down synchronously. The filter 52 can also be retracted and extended to adapt to changes in the length of the purification filter 52, thereby maintaining the overall position of the filter holes on the purification filter 52 unchanged. During the up and down movement of the filter hole adjustment plate 64, the position of the filter holes on the filter hole adjustment plate 64 can be driven to move up and down. When the filter hole adjustment plate 64 moves up and down, the position of the filter holes on the filter hole adjustment plate 64 and the purification filter 52 can be adjusted. The smaller the positional deviation between the filter holes on the filter hole adjustment plate 64 and the filter holes on the purification filter 52, the larger the filter holes formed by the filter hole adjustment plate 64 and the purification filter 52. The larger the positional deviation between the filter holes on the filter hole adjustment plate 64 and the filter holes on the purification filter 52, the smaller the filter holes formed by the filter hole adjustment plate 64 and the purification filter 52. Therefore, the bottom sliding seat 53 can drive the bottom mounting seat 61 to move inside the purification channel 3 to adjust the size of the filter holes formed by the purification filter 52 and the filter hole adjustment plate 64.

[0064] Example 4:

[0065] The difference from the above embodiment is that, please refer to Figure 1 - Figure 11 The driving mechanism 4 includes a power motor 41, which is installed inside the bottom sliding seat 53. A power shaft 42 is installed on the driving end of the power motor 41, a transmission roller 43 is installed on the outside of the power shaft 42, a forward ratchet 44 is installed on the outside of the power shaft 42, an adjustment dial 45 is installed on the outside of the power shaft 42, and a reverse ratchet 46 is installed on the outside of the power shaft 42. A ratchet clamping mechanism 47 is installed on the outside of the transmission roller 43 and the adjustment dial 45.

[0066] The outside of the adjusting dial 45 is connected to the inner wall of the air conditioning unit body 1 through a centrifugal connecting rod 48 , and the connection between the adjusting dial 45 and the centrifugal connecting rod 48 is at the edge of the adjusting dial 45 .

[0067] The outside of the power shaft 42 is connected to the ratchet clamping mechanism 47 on the outside of the transmission roller 43 through the forward ratchet 44, and the outside of the power shaft 42 is connected to the ratchet clamping mechanism 47 on the outside of the adjustment dial 45 through the reverse ratchet 46.

[0068] When the power shaft 42 rotates forward, it can drive the transmission roller 43 to rotate forward through the engagement of the forward ratchet 44 with the ratchet engaging mechanism 47 on the power shaft 42. When the transmission roller 43 rotates forward, it can drive the filter collection reel 54 to rotate through the transmission connection between the transmission belt 56 and the reel roller 55. When the power shaft 42 rotates reversely, it can drive the adjusting dial 45 to rotate reversely through the engagement of the reverse ratchet 46 with the ratchet engaging mechanism 47 on the adjusting dial 45. When the adjusting dial 45 rotates, it can drive the bottom sliding seat 53 to move at the bottom of the purification channel 3 through the connection structure between the centrifugal connecting rod 48 and the inner wall of the air-conditioning unit body 1.

[0069] The ratchet engaging mechanism 47 includes an engaging sliding sleeve 471 . The driving roller 43 and the adjusting dial 45 are both externally mounted with the engaging sliding sleeve 471 . A engaging spring 472 is mounted internally of the engaging sliding sleeve 471 . The movable end of the engaging spring 472 is connected to a ratchet engaging block 473 . The ratchet engaging block 473 is slidably mounted internally of the engaging sliding sleeve 471 .

[0070] The bottom of the ratchet clamping block 473 is an inclined structure. The ratchet clamping block 473 is clamped with the outside of the forward ratchet 44 and the reverse ratchet 46 through the bevel angle of the bottom. The inclination directions of the forward ratchet 44 and the reverse ratchet 46 are opposite. The bottom bevel angle of the ratchet clamping block 473 on the transmission roller 43 and the bottom bevel angle of the ratchet clamping block 473 on the adjustment dial 45 are opposite in inclination direction.

[0071] When the power shaft 42 drives the reverse ratchet 46 to rotate forward, the reverse ratchet 46 can drive the forward ratchet 44 and the reverse ratchet 46 to rotate synchronously, and the inclination directions of the teeth on the forward ratchet 44 and the reverse ratchet 46 are opposite. When the power shaft 42 drives the forward ratchet 44 to rotate forward, the forward ratchet 44 can engage with the ratchet engaging block 473 on the transmission roller 43 to drive the transmission roller 43 to rotate. When the transmission roller 43 rotates, the transmission belt 56 and the winding rod roller 55 can drive the filter collection reel 54 to rotate inside the bottom sliding seat 53. When the filter collection reel 54 rotates inside the bottom sliding seat 53, the purification filter 52 can be reeled in. When the power shaft 42 drives the reverse ratchet 46 to rotate forward, the reverse ratchet 46 can squeeze the ratchet engaging block 473 on the adjusting dial 45 into the interior of the engaging sliding sleeve 471, thereby When the wheel 46 rotates forward, it cannot drive the adjusting dial 45 to rotate. When the power shaft 42 drives the forward ratchet 44 to rotate reversely, the forward ratchet 44 can squeeze the ratchet clamping block 473 on the transmission roller 43 into the interior of the clamping sliding sleeve 471, so that when the forward ratchet 44 rotates reversely, it cannot drive the transmission roller 43 to rotate. When the power shaft 42 drives the reverse ratchet 46 to rotate reversely, the reverse ratchet 46 can engage with the ratchet clamping block 473 on the adjusting dial 45 to drive the adjusting dial 45 to rotate. When the adjusting dial 45 rotates, it can drive the power motor 41 and the bottom sliding seat 53 to move back and forth through the connection between the centrifugal connecting rod 48 and the inner wall of the air-conditioning unit body 1, so that when the power shaft 42 moves forward, it can drive the filter collection reel 54 to reel up the purification filter 52, and when the power shaft 42 rotates reversely, it drives the adjusting dial 45 to rotate to adjust the position of the bottom sliding seat 53.

[0072] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
