[0084] For the louvered wind blocking section using the power input end, other louvered wind blocking sections do not need to output power to the linkage mechanism through the power transmission end, therefore, in some embodiments, the opening is in a closed state or is provided with an opening switch for closing or opening the opening, by closing or sealing the opening, the power source of the linkage mechanism is the power input end, such a louvered wind blocking section can ensure independent control of the rotation of the wind blocking blades without external influence, and when external control of the rotation of the wind blocking blades is needed, the opening can be opened.

[0085] In addition, in most embodiments of the utility model, the length direction of the support arm in the louvered wind blocking section is the same as the length direction of the air conditioner air outlet, so that when facing air conditioner air outlets of different lengths, generally only different lengths of support arms need to be replaced, without replacing the entire wind blocking structure, the previously used wind blocking blades can still be used, and the replacement cost can be greatly reduced.

[0086] The support arm is also provided with an external connecting position for fixing the support arm opposite the air conditioner air outlet, the external connecting position comprises one of a sliding rail, a sliding block or a mounting position, by using a hanging rack hung on the air conditioner and selecting a structure matched with the sliding rail, the sliding block or the mounting position, the support arm can be fixed at a position opposite the air conditioner air outlet, and a person skilled in the art can select a connection point of the hanging rack and the support arm, which can be fixed or changed along the sliding rail.

[0087] Although a single louvered wind blocking section can be used alone as long as its length is basically the same as the length of the air conditioner air outlet, in a more common case, the length of a single louvered wind blocking section is shorter than the length of the air conditioner air outlet, therefore, the utility model also provides a series body of louvered wind blocking sections, in some embodiments, the series body of louvered wind blocking sections is a first series body, the first series body comprises at least two louvered wind blocking sections connected with each other through external connecting ends, none of the louvered wind blocking sections is provided with a power input end, and the first series body can extend the wind blocking area of the synchronously rotating wind blocking blades, in some embodiments, the series body of louvered wind blocking sections is a second series body, the second series body comprises at least two louvered wind blocking sections connected with each other through external connecting ends, at least one of the louvered wind blocking sections is provided with a power input end, for example, in one case, the second series body has only one louvered wind blocking section provided with a power input end, and all the louvered wind blocking sections can be driven to rotate the wind blocking blades by the power provided by the power input end, so that all the wind blocking blades rotate synchronously, in another case, all the louvered wind blocking sections in the second series body are provided with power input ends, and the wind blocking blades in each louvered wind blocking section rotate independently, thereby providing air conditioning outlet in multiple directions.

[0088] In view of the fact that the connection firmness of the series body formed by directly connecting the louvered wind blocking segments in series cannot be guaranteed, some embodiments are provided with a connecting fastener on the series body of the louvered wind blocking segments, at least two adjacent louvered wind blocking segments are connected by the connecting fastener, the external connecting end is connected with the adjacent support arm by the connecting fastener, the connecting fastener is a connecting sleeve which at least partially covers the external connecting end or a plug which at least partially inserts the external connecting end, the connecting fastener in some embodiments is provided with a channel, the channel is for the power transmission end which first passes through the opening to pass through and connect with the power transmission end on the adjacent support arm, in some embodiments, the connection of the external connecting end with the connecting fastener and the connection of the power transmission end are synchronous, for example, when the external connecting end is connected with the connecting fastener, the power transmission end which passes through the channel is connected with the power transmission end on the adjacent support arm, while in other embodiments, the connection of the external connecting end with the connecting fastener and the connection of the power transmission end are not synchronous, for example, the external connecting end is provided with a far connection position and a near connection position in turn along the direction from the external connecting end to the middle part of the support arm, when the connecting fastener is connected with the external connecting end at the far connection position on both sides, the power transmission end is separated from the power transmission end on the adjacent support arm, when the connecting fastener is connected with the external connecting end at the near connection position on at least one side, the power transmission end which passes through the channel is connected with the power transmission end on the adjacent support arm, in this way, if the user wants to realize the synchronous rotation of all the wind blocking blades in the series body of the louvered wind blocking segments, the connecting fastener is connected with the external connecting end at the near connection position on at least one side, while if the user wants to realize the independent rotation of the wind blocking blades on different support arms, the connecting fastener is connected with the external connecting end at the far connection position on both sides, the operation is very simple.

[0089] Unlike the setting of the channel, the connecting fastener in some embodiments sets a transfer linkage mechanism, which is connected with the power transmission end passing through the opening and connected with the power transmission end on the adjacent support arm through the transfer linkage mechanism. In some embodiments, the connection of the external end with the connecting fastener is synchronous with the connection of the power transmission end, for example, when the external end is connected with the connecting fastener, the power transmission end passing through the opening is connected with the transfer linkage mechanism, and in other embodiments, the connection of the external end with the connecting fastener is not synchronous with the connection of the power transmission end, for example, the external end is provided with a far connection position and a near connection position in the external end to the middle of the support arm in sequence, when the connecting fastener is connected with the external end at the far connection position on both sides, the power transmission end is separated from the transfer linkage mechanism, and when the connecting fastener is connected with the external end at the near connection position on at least one side, the power transmission end passing through the opening is connected with the transfer linkage mechanism. In this way, if the user wants to realize the synchronous rotation of all the wind deflector blades in the series connection body of the louvered wind deflector section, the connecting fastener is connected with the external end at the near connection position on at least one side, and if the user wants to realize the independent rotation of the wind deflector blades on different support arms, the connecting fastener is connected with the external end at the far connection position on both sides, which is also very simple to operate.

[0090] As for the specific transfer linkage mechanism, it can be determined according to the specific form of the power transmission end. As described above, the power transmission end can be one of a transmission gear, a transmission rod or a transmission rack, and the transfer linkage mechanism is a transfer rod connected with the transmission rod or a transfer gear engaged with the transmission gear. As described above, the external end and the connecting fastener can also be connected by clamping or magnetic attraction, and the specific connection structure can be referred to the foregoing description. The present utility model also preferably adopts magnetic attraction. Similarly, as described above, the power transmission end and the power transmission end on the adjacent support arm can also be connected by clamping or magnetic attraction, and the power transmission end and the transfer linkage mechanism can also be connected by clamping or magnetic attraction. The specific connection structure can be referred to the foregoing description. The present utility model also preferably adopts magnetic attraction.

[0091] As described above, the series connection body of the louvered wind deflector section can also be provided with an external connection position on the connecting fastener, which fixes the connecting fastener in a position where the louvered wind deflector section faces the air outlet of the air conditioner. The external connection position includes one of a sliding rail, a sliding block or a mounting position. By using a hanging rack hung on the air conditioner and selecting a structure matching the sliding rail, the sliding block or the mounting position, the connecting fastener can be fixed in a position where the louvered wind deflector section faces the air outlet of the air conditioner.

[0092] The utility model also provides a connecting arm, the connecting arm is used for lengthening the support arm in louvered wind shielding section, but is not connected with the wind shielding blade, and is used for coping with the use situation that needs longer louvered wind shielding section and does not need more wind shielding area. The connecting arm is connected with the external terminal of support arm, in part embodiment, the connecting arm is equipped with passageway, the passageway is passed and is connected with the power transmission end on the other support arm through the opening, in other embodiment, the connecting arm is equipped with adapter linkage mechanism, the adapter linkage mechanism is connected with the power transmission end on the other support arm through the opening and is connected through adapter linkage mechanism. Specifically, the power transmission end is one of transmission gear, transmission rod or transmission rack, and the adapter linkage mechanism is adapter rod connected with transmission rod or transmission rack or adapter gear engaged with transmission gear.

[0093] In part embodiment, at least one end of the connecting arm is same with the external terminal structure of support arm, so that the connecting arm still has the same external terminal with the original support arm after being connected with the support arm, thereby can be smoothly connected with the other support arm. Of course, the skilled person can also refer to the connecting fastener in the foregoing when implementing the connecting arm.

[0094] The utility model further provides a kind of air conditioner wind shielding system, including at least two air conditioner air outlets being arranged in series with each other, closed place being provided between adjacent two air conditioner air outlets and closing air conditioner air outlet, and the system further includes the series connection body of louvered wind shielding section, the series connection body includes blank section not connected with wind shielding blade and wind shielding section connected with wind shielding blade, the length of the blank section is same with the length of closed place and is opposite closed place, and the wind shielding section is opposite air conditioner air outlet.The blank section can obviously include the part of support arm not connected with wind shielding blade and / or connecting fastener, and the system can ensure that closed place without air conditioner air outlet is not configured any wind shielding facility, so that the wind shielding utilization degree of the series connection body of louvered wind shielding section is highest.

[0095] Embodiment 1

[0096] See Figure 1 The embodiment provides a louvered wind shielding section, Figure 1The structure of one end of the louvered wind shield section is shown, including a support arm 5, a wind shield louver 1, and a linkage mechanism. The middle of the wind shield louver 1 extends a rotating shaft 9 in the direction of the support arm. The support arm 5 is provided with a rotating bearing 3 at a position corresponding to the rotating shaft 9. The rotating shaft 9 is inserted into the rotating bearing 3 to form a rotating joint. In order to facilitate the installation and removal of the rotating shaft 9 on the rotating bearing 3, a slide 10 is provided on the rotating bearing 3 for the rotating shaft 9 to slide into the rotating bearing hole. The side of the linkage mechanism facing the wind shield louver 1 is a rack 7. The support arm 5 is provided with a containing space 4 for accommodating the linkage mechanism. The rotating shaft 9 is provided with a gear 2 that matches the rack 7. The rack 7 reciprocates in the containing space 4 of the support arm 5 and can drive the wind shield louver 1 to rotate relative to the support arm 5 through the gear 2. The reciprocating movement of the linkage mechanism in the containing space 4 is limited, one of the reasons being to prevent the rotation angle of the wind shield louver 1 relative to the support arm 5 from exceeding a certain range, such as 0°-180°, 30°-120°, etc. Therefore, a blocking wall 6 is provided on the linkage mechanism, and a limiting block 8 is provided in the support arm 5. The reciprocating movement of the linkage mechanism in the containing space 4 is limited by the movement of the limiting block 8 relative to the blocking wall 6, i.e. when the blocking wall 6 blocks the limiting block 8, the linkage mechanism stops moving.

[0097] As an alternative to the louvered wind shield section described in this embodiment, the distance between the two wind shield louvers 1 is short, for example, less than the width of the wind shield louver 1. The upper part of the wind shield louver 1 is provided with a blocking surface 22, and the lower part of the wind shield louver 1 is provided with a blocking surface 21. When the blocking surface 21 of the lower part of the wind shield louver 1 abuts against the blocking surface 22 of the upper part of the wind shield louver 1, the wind shield louver 1 is prevented from continuing to rotate. This can replace the function of the limiting block 8 and the blocking wall 6, but the limiting block 8 and the blocking wall 6 can set the rotation angle of the wind shield louver 1 in any rotation range, and only need to adjust the maximum distance between the limiting block 8 and the blocking wall 6. In order to prevent the linkage mechanism from escaping from the containing space, the top of the limiting block 8 is provided with a stop block that blocks the linkage mechanism, allowing the linkage mechanism to move within the containing space. A special stop block is a cover plate that covers the containing space.

[0098] As another alternative to the louvered wind shield section described in this embodiment, the end of the linkage mechanism is provided with a limiting block 24, and the side of the support arm facing the end of the linkage mechanism is provided with a blocking wall 23. When the blocking wall 23 abuts against the limiting block 24, the linkage mechanism can stop moving.

[0099] See Figure 2 , Figure 2 In Figure 1The diagram further shows the power input end. The louvered windbreak section also includes a power input end, which includes an operating lever 16 for manual operation by the user. Since the side of the linkage mechanism connected to the power input end is not a rack but a linkage rod 25, the linkage mechanism is a linkage rod relative to the power input end. The linkage rod 25 is provided with a connecting groove 18. The power input end also includes a push-pull strip 17 inserted into the connecting groove 18. The push-pull strip 17 can push and pull the linkage rod 25. The linkage rod 25 and the push-pull strip 17 are rotatably connected through the connecting groove 18. The push-pull strip 17 is fixedly connected to the operating lever 16.

[0100] See Figure 3 , Figure 3 It shows another kind of difference from Figure 2 The power input end of the linkage mechanism is connected to a rack 19 on the side facing the power input end. The power input end includes a power gear 20 that drives the rack 19 to move.

[0101] See Figure 4 , Figure 4 yes Figure 3 The diagram shows a comparison of the structure before and after assembly. The left side of the diagram shows the structure before assembly, and the right side shows the structure after assembly. The diagram shows a protrusion 28 located at the end of the operating lever and protruding outwards as a whole relative to the end of the operating lever. The support arm has a blocking surface 26 that blocks the protrusion 28, and the linkage mechanism has a blocking surface 27 that blocks the protrusion 28. During assembly, part of the operating lever is first passed through the space enclosed by the blocking surface 26 and blocked by the protrusion 28. Then the linkage mechanism is installed. The blocking surfaces 26 and 27 restrict the movement space of the protrusion 28 to prevent the operating lever from detaching from the linkage mechanism.

[0102] Example 2

[0103] See Figure 5 , Figure 5 The diagram shows the structure of one end of another louvered windbreak section, which is partly the same as that in Embodiment 1, for example, including a support arm and windbreak blades 29. A gear 32 is provided on the rotating shaft of the windbreak blades 29. The main difference is that the linkage mechanism is a linkage gear 30, which is located between two adjacent rotating shafts. One end of the operating lever is provided with a gear 31 that meshes with both the gear 32 and the linkage gear 30.

[0104] Example 3

[0105] See Figure 6 , Figure 6 This shows the structure of one end of another louvered windbreak section, which is related to... Figure 5The structures are generally the same. For example, the linkage mechanism has a connecting groove 34 on the side facing the power output end. The power input end also includes an operating rod and a push-pull bar 35 that is inserted into and rotatably connected to the connecting groove 34. The main difference is that the power input end also includes a gear 37 and a rotating wheel 35. The push-pull bar 35 is fixed to the gear 37 through the rotating wheel 36. One end of the operating rod is provided with a thread that meshes with the gear 37. Rotating the operating rod can indirectly push and pull the linkage mechanism by pushing and pulling the push-pull bar 35.

[0106] Example 4

[0107] See Figure 7 , Figure 7 This shows the structure of one end of another louvered windbreak section, as described in Embodiment 1. Figure 1 The louvered windbreak section is the same, the main difference being that the linkage mechanism is a worm gear 39. The power input end includes a connecting shaft connected to the worm gear 39 and an operating lever. A gear 40 is provided on the connecting shaft, and one end of the operating lever has a thread 41 that meshes with the gear 40. Rotating the operating lever drives the worm gear 39 to rotate. As an improvement in this embodiment, the gear 40 is a bevel gear, and one end of the operating lever is provided with another bevel gear that matches the bevel gear. The operating lever controls the rotation of the worm gear 39 through the bevel gear set.

[0108] Example 5

[0109] See Figure 8 , Figure 8 This shows the structure of one end of another louvered windbreak section, which is related to... Figure 6 The basic structure is largely the same, with the main difference being that the rotating shaft connected to the windshield blade has a rotating bar 42, and the linkage mechanism has a connecting groove 43 on the side facing the windshield blade for the rotating bar 42 to be inserted. The rotating bar 42 and the linkage mechanism are rotatably connected through the connecting groove 43. The movement of the linkage mechanism can drive the windshield blade to rotate by the rotating bar 42 inserted into the connecting groove 43.

[0110] Example 6

[0111] This embodiment demonstrates a structure that connects two louvered windbreak sections described in Embodiment 1 in series. Figure 9 , Figure 9 The louvered windbreak section described in Example 1 is shown. Figure 1 The structure shown is before the two ends of the support arm 5 are connected (only the support arm portion is shown). The support arm 5 has an external end, with a slot 11 on some of the external ends and a locking block 12 on others. When the locking block 12 is inserted into the slot 11, the two louvered windbreak sections can be connected in series. Of course, those skilled in the art can also... Figure 1 The end of the support arm shown is as followsFigure 9 The end of the support part is modified so that both ends of the support arm in the louvered wind blocking section of Embodiment 1 can be connected in series with other support arms. The clamping groove 11 and the clamping block 12 can also be magnets, which are connected by magnetic attraction.

[0112] Embodiment 7

[0113] See Figure 10 , this embodiment is based on Embodiment 6 to supplement the linkage mechanism and the power transmission end, the linkage mechanism is a rack 62, the power transmission end is a transmission rod 60, the support arm is provided with an opening 61 for the transmission rod 60 to pass through, the support arm is connected to another support arm through the external end, the transmission rod 60 can pass through the opening 61 and be connected to the transmission rod 63 on another support arm, in this embodiment, the above two connections are not synchronized, as shown in Figure 10 , although the two support arms have been connected to each other, when the transmission rod 60 is not connected to the transmission rod 63, the transmission rod 61 is provided with a clamping block, and the transmission rod 63 is provided with a clamping groove, the user needs to connect the two support arms to each other and then connect them. Figure 11 This embodiment is improved, that is, a magnet 64 is arranged on the transmission rod, when the two support arms are connected to each other, the two transmission rods are also connected to each other through the magnet 64, so the connection of the support arm to another support arm through the external end is synchronized with the connection of the transmission rod to another transmission rod.

[0114] Embodiment 8

[0115] See Figure 12 , this figure shows that the power transmission end in this embodiment can be a transmission gear 65, the gear 66 is connected to the rotating shaft of the wind deflector blade, the linkage mechanism is a linkage gear 67, which is different from the transmission rod and the rack structure or connection method described in Embodiment 7, the transmission gear 65 of this embodiment is engaged with the gear 66, but not directly engaged with the linkage gear 67, the external end of the support arm is also provided with an opening 68 for the transmission gear 65 to pass through, specifically, part of the teeth of the transmission gear 65 protrude outward through the opening 68, so as to engage with the transmission gear on the other support arm, that is, as described in Embodiment 7, when the external end of the support arm is connected to the other support arm, the transmission gear 65 is engaged with the transmission gear on the other support arm. Of course, one improvement of this embodiment is to replace the transmission gear 65 with a transmission gear set, the effect of which can be seen in the relevant content of the specific embodiment.

[0116] Embodiment 9

[0117] See Figure 13This embodiment demonstrates a structure different from the structure described in Embodiment 6, which connects two louvered windbreak sections as described in Embodiment 1 in series. The main difference lies in the fact that a far connection position 69 and a near connection position 70 are sequentially arranged along the outer end of the support arm towards the middle of the support arm. Furthermore, a linkage mechanism and a power transmission end are added. The linkage mechanism is a worm gear 71, and the power transmission end is a transmission rod 72 connected to the worm gear 71. A corresponding transmission rod 73 is also provided on the other support arm, except that the transmission rod 72 has a plug, while the transmission rod 73 has a groove. Figure 13 In this state, the support arm is engaged with another support arm at the far connection position 69. At this time, the transmission rod 72 and the transmission rod 73 are still in a separated state. Figure 14 In this state, the support arm engages with another support arm at a near connection position 70, at which point the transmission rods 72 and 73 are engaged. Therefore, the user can visually determine whether the transmission rods are connected by observing different connection positions.

[0118] Example 10

[0119] See Figure 15 In Examples 10 and 9 Figure 13 The states are exactly the same, the only difference being that the transmission rod 74 is equipped with a magnet, and the opening 75 through which the transmission rod 74 passes is in Figure 15 The opening is open, but it can actually be closed. After closing, the transmission rods 74 can still be magnetically connected to each other through the opening via magnets. Of course, it is also possible to set a switch on the opening 75 without affecting the magnetic connection of the transmission rods 74.

[0120] Example 11

[0121] Example 8 shows that the transmission gear does not mesh with the linkage mechanism, but rather meshes with a gear set on the rotating shaft of the windshield. As for the various structures on the rotating shaft of the windshield, this example refers to the various structures described in Examples 1-5, and correspondingly replaces the transmission gear with a transmission rod or a transmission rack.

[0122] Example 12

[0123] See Figure 16 This embodiment provides a simple series connection of louvered windbreak sections, which includes two louvered windbreak sections and connecting fasteners 14. More complex series connections often include at least three or more louvered windbreak sections. In fact, Figure 10-11 , Figure 13-15 The series connection of the louvered windbreak sections has already been partially shown, with the support arms of this series connection directly connected to each other. However, in this embodiment, the series connection of the louvered windbreak sections adds a connecting fastener 14 between the two louvered windbreak sections. This connecting fastener 14 at least strengthens the connection strength between the two louvered windbreak sections. Figure 16The outer end of the support arm is not provided with an obvious external connection structure such as the clamping structure mentioned above, but can be provided with a magnet, and two support arms can be connected in series by means of the connecting member 14, which can also play the role of external connection.

[0124] See Figure 16 The outer end of the support arm 5 is only provided with an opening 13 for the power transmission end, and the connecting fastener 14 is a connecting sleeve, which sleeves the outer end of the support arm 5 on both sides, thereby connecting two support arms in series. The connecting member 14 is provided with a channel 15, and the power transmission end passing through the opening 13 is connected with the power transmission end on the other support arm 5 through the channel 15. The specific structure of the power transmission end can be referred to the previous embodiments. When the connecting fastener is clamped on both sides of the outer end of the support arm (of course, it can also be magnetically connected), the power transmission ends on the support arms are connected with each other. The louvered wind deflector section can be selected to have a power input end or not to have a power input end, so that the series body composed of louvered wind deflector sections without a power input end only prolongs the wind deflection range and cannot rotate the wind deflector blades, but after being connected in series with the series body of the louvered wind deflector sections containing at least one power input end, the wind deflector blades can be rotated to produce a wind deflection effect. The specific structure of the power input end can be referred to the previous embodiments. This embodiment does not show the specific structure inside the support arm. In fact, the power input end can be provided on the series body, and then the wind deflection area controlled by the louvered wind deflector section with a power input end has the ability to independently control the wind deflection direction.

[0125] Embodiment 13

[0126] See Figure 17 This embodiment provides a special series body of louvered wind deflector sections, which uses two Figure 12The louvered wind blocking section and the connecting fastener 46 which is sleeved on the outer end of the two louvered wind blocking section supporting arms, the outer end of the supporting arm is provided with an opening 45, the transmission gear 44 which is adjacent to the opening 45 passes through the opening 45, the teeth of part of the transmission gear 44 pass through the opening 45 and the channel of the connecting fastener 46 and are engaged with the transmission gear on the other supporting arm. The connecting fastener is provided with a clamping hole 49 and a clamping hole 48 which are clamped with the clamping head 47 of the supporting arm outer end, the clamping head 47 is provided with a far connecting position at the outer end of the supporting arm and a near connecting position 76, when the clamping head 47 is clamped with the clamping hole 48, the outer end of the supporting arm is connected with the connecting fastener 46 at the far connecting position, at this time, the transmission gears 44 are separated, so that all the wind blocking blades of the series connection body of the louvered wind blocking section cannot be synchronously rotated, but the wind blocking blades on the two supporting arms are independently synchronously rotated, and when the clamping head 47 is clamped with the clamping hole 49, the outer end of the supporting arm is connected with the connecting fastener 46 at the near connecting position 76, at this time, the transmission gears 44 are engaged with each other. Therefore, all the wind blocking blades of the series connection body of the louvered wind blocking section can be synchronously rotated.

[0127] Embodiment 14

[0128] This embodiment separately shows the supporting arm, see Figure 18 The figure shows that the supporting arm is provided with a mounting position 50 on one side, which can fix the supporting arm at a position opposite to the air outlet of the air conditioner.

[0129] Embodiment 15

[0130] See Figure 19 This embodiment is an improvement of embodiment 13, the main difference is that the adapter linkage gear 53 is arranged in the connecting fastener 52, and there is no longer a channel, when the outer end of the supporting arm is connected with the connecting fastener 52 and is at the near connecting position 78, the transmission gears 51 and 54 which are adjacent to the opening in the two outer ends of the supporting arms connected by the connecting fastener 52 are engaged with the adapter linkage gear 53, so that all the wind blocking blades of the series connection body of the louvered wind blocking section can be synchronously rotated in the same direction, when the outer end of the supporting arm is connected with the connecting fastener 52 and is at the far connecting position 56, at least one of the transmission gears 51 and 54 which are adjacent to the opening in the two outer ends of the supporting arms connected by the connecting fastener 52 is separated from the adapter linkage gear 53, so that all the wind blocking blades of the series connection body of the louvered wind blocking section cannot be synchronously rotated, but the wind blocking blades on the two supporting arms are independently synchronously rotated.

[0131] Embodiment 16

[0132] The embodiment shows an air conditioner wind blocking system, which comprises two air conditioner air outlets 80 arranged in series, a closed part 81 for closing the air conditioner air outlet arranged between the two adjacent air conditioner air outlets 80, the closed part 81 being unable to produce air conditioner air outlet, and a series connection of louver wind blocking sections, the series connection of louver wind blocking sections comprising a blank section 83 without wind blocking blades and a wind blocking section 82 with wind blocking blades, the length of the blank section 83 being the same as the length of the closed part 81 and facing the closed part, and the wind blocking section 82 facing the air conditioner air outlet 80. The blank section obviously can comprise the part of the supporting arm without wind blocking blades and / or the connecting fastener, and the system can ensure that the closed part 81 without air conditioner air outlet is not provided with any wind blocking facility, so that the wind blocking utilization of the series connection of louver wind blocking sections is the highest.

[0133] The basic principle, main features and advantages of the air conditioner wind blocking system are shown and described above. It should be understood by the person skilled in the art that the air conditioner wind blocking system is not limited by the above embodiments, the above embodiments and the description in the specification are only for illustrating the principle of the air conditioner wind blocking system, and the air conditioner wind blocking system can have various changes and improvements without departing from the spirit and scope of the air conditioner wind blocking system, and these changes and improvements all fall within the scope of the claimed air conditioner wind blocking system.
