[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown in the figure, a buffer water-blocking structure in front of the fan of a HVAC unit according to an embodiment of the present invention includes a housing 1. A fixing rod 11 is fixedly connected inside the housing 1, and four fixing rods 11 are arranged correspondingly. A stop block 12 is provided inside the housing 1, and multiple stop blocks 12 are arranged in a linear array. A push block 120 is fixedly connected to the side wall of one of the stop blocks 12. A fixing sleeve 13 is fixedly connected to the side wall of the stop block 12. A spring 14 is fixedly connected between adjacent fixing sleeves 13. A threaded cylinder 15 is fixedly connected to the side wall of the push block 120, and a regulating valve 16 is threadedly connected inside the threaded cylinder 15. A gear 17 meshes with the top of the regulating valve 16. A motor 18 is fixedly connected inside the housing 1. During operation, the gear 17 is rotatably connected to the housing 1, and the gear 17 is fixedly connected to the output end of the motor 18. During the operation of the air conditioner, the operator can drive the motor... The motor 18 drives the gear 17 to rotate. After the gear 17 rotates, the regulating valve 16, which is meshed with the gear 17, will rotate synchronously. Since the threaded cylinder 15, which is fixed to the side wall of the push block 120, is threadedly connected to the regulating valve 16, and the stop block 12, which is fixed to the push block 120, is limited by the fixing rod 11, the push block 120 will be displaced. The stop block 12, which is fixed to the push block 120, will move synchronously. Since the springs 14, which are fixed between adjacent fixed sleeves 13, have the same elastic coefficient, multiple stop blocks 12 will have approximately the same displacement, and the gap between adjacent stop blocks 12 will change. Through the above structure, the motor 18 drives the push block 120 to produce displacement, and the same springs 14 are set between multiple stop blocks 12. Then, by means of the principle of force interaction, multiple stop blocks 12 will produce equidistant displacement, which improves the flexibility of the water-blocking structure.

[0026] like Figures 2 to 4As shown, a first movable block 2 is fixedly connected to the side wall of one of the stop blocks 12, and the two first movable blocks 2 are arranged correspondingly; a second movable block 22 is fixedly connected to the side wall of one of the stop blocks 12, and the two second movable blocks 22 are arranged correspondingly; a first fixed block 21 and a second fixed block 23 are fixedly connected to the inner side wall of the outer shell 1, and the first fixed block 21 and the second fixed block 23 are respectively positioned and sized to correspond to the first movable block 2 and the second movable block 22; during operation, the two first fixed blocks 21 fixed to the inner side wall of the outer shell 1 contact the inside of the first movable block 2, and whenever the stop block 12 with the first movable block 2 fixed to it moves, the first fixed block 21 remains inside the first movable block 2, and at the same time... The second movable block 22, fixed to the side wall of the baffle 12, and the second fixed block 23, fixed to the side wall of the outer shell 1, are in contact with each other. When the baffle 12, to which the second movable block 22 is fixed, moves, the second movable block 22 and the second fixed block 23 also remain in contact. When liquid passes through, the first movable block 2, the first fixed block 21, the second movable block 22, and the second fixed block 23 can contact each other to prevent liquid from entering the baffle. Through the above structure, the first movable block 2, the first fixed block 21, the second movable block 22, and the second fixed block 23 are set to fill the gap between the baffle 12 and the outer shell 1, thereby preventing liquid from passing through the gap between the outer shell 1 and the baffle 12, and improving the water-blocking ability and practicality of the baffle.

[0027] like Figure 2 , Figure 4 and Figure 5 As shown, a first protrusion 3 and a second protrusion 31 are fixedly connected to the side wall of the baffle 12, and the first protrusion 3 and the second protrusion 31 are arranged correspondingly. When working, the first protrusion 3 and the second protrusion 31 fixed to the side wall of the baffle 12 are semi-circular, and the semi-circular shape faces the air intake side of the air conditioner. Through the above structure, the semi-circular first protrusion 3 and the second protrusion 31 block the liquid stream, increase the water blocking capacity of the baffle 12, and help solve the problem of the wind driving the liquid stream through the baffle when there is too much liquid, thus improving the water blocking capacity of the baffle.

[0028] like Figure 5 As shown, a limiting rod 4 is fixedly connected to the side wall of the push block 120; a limiting cylinder 41 is fixedly connected to the inner side wall of the outer shell 1, and the limiting rod 4 is slidably connected inside the limiting cylinder 41; during operation, the limiting rod 4 fixed to the side wall of the push block 120 is slidably connected inside the limiting cylinder 41, and whenever the push block 120 moves, the limiting cylinder 41 can limit the push block 120 by means of its relationship with the limiting rod 4; through the above structure, the limiting rod 4 and the limiting cylinder 41 limit the push block 120, which helps to prevent the push block 120 from tilting or detaching under stress, enhances the structural stability of the baffle, and helps to extend the service life of the baffle.

[0029] like Figures 3 to 5As shown, ventilation slots 5 are provided on the side wall of the outer casing 1, and multiple ventilation slots 5 are arranged in a corresponding manner. During operation, the liquid between the outer casing 1 and the baffle 12 evaporates naturally and can be discharged through the ventilation slots 5 on the side wall of the outer casing 1. Through the above structure, the water vapor between the outer casing 1 and the baffle 12 is discharged by setting ventilation slots 5 on the side wall of the outer casing 1, which helps to keep the inside of the baffle dry and reduces the maintenance requirements of the baffle.

[0030] like Figure 4 As shown, a protective cover 6 is fixedly attached to the side wall of the outer casing 1; an exhaust hole 61 is provided on the side wall of the protective cover 6; during operation, the protective cover 6 fixed to the side wall of the outer casing 1 can protect the regulating valve 16 and the gear 17 by itself, avoiding external interference. At the same time, since the side wall of the protective cover 6 has an exhaust hole 61, water vapor can be discharged through the exhaust hole 61. Through the above structure, the protective cover 6 protects the regulating valve 16 and the gear 17, which helps to avoid external interference to the normal operation of the regulating valve 16 and the gear 17 and improves the stability of the baffle.

[0031] like Figures 1 to 5 As shown, the outer shell 1, fixing rod 11, stop block 12, and fixing sleeve 13 are made of stainless steel. During operation, the use of stainless steel in the outer shell 1, fixing rod 11, stop block 12, and fixing sleeve 13 allows the high structural strength and strong oxidation resistance of stainless steel to be fully utilized. Through the above, the use of stainless steel in the outer shell 1, fixing rod 11, stop block 12, and fixing sleeve 13 enhances their structural strength and oxidation resistance, which is beneficial to extending the service life of the baffle.

[0032] During operation, gear 17 is rotatably connected to housing 1, and gear 17 is fixedly connected to the output end of motor 18. During air conditioner operation, the operator can drive gear 17 to rotate via motor 18. After gear 17 rotates, regulating valve 16, which meshes with gear 17, will rotate synchronously. Since the threaded cylinder 15, fixed to the side wall of push block 120, is threadedly connected to regulating valve 16, and the stop block 12, fixedly connected to push block 120, is limited by fixing rod 11, push block 120 will displace, becoming fixedly connected to... The stop blocks 12 will move synchronously. Since the springs 14 fixed between adjacent fixed sleeves 13 have the same elastic coefficient, multiple stop blocks 12 will undergo approximately the same displacement, and the gap between adjacent stop blocks 12 will change. The two first fixed blocks 21 fixed to the inner wall of the outer shell 1 contact the inside of the first movable block 2. Whenever the stop block 12 fixed to the first movable block 2 moves, the first fixed block 21 remains inside the first movable block 2. At the same time, the second movable block 22 fixed to the side wall of the stop block 12 and the second fixed block fixed to the side wall of the outer shell 1... When the stop block 12, which is fixed to the second movable block 22, moves, the second movable block 22 and the second fixed block 23 also remain in contact. When liquid passes through, the first movable block 2, the first fixed block 21, the second movable block 22, and the second fixed block 23 can contact each other to prevent liquid from entering the baffle. The first protrusion 3 and the second protrusion 31 fixed to the side wall of the stop block 12 are semi-circular, and the semi-circle faces the air inlet side of the air conditioner. The limiting rod 4 fixed to the side wall of the push block 120 is slidably connected to the inside of the limiting cylinder 41. Whenever the push block 120 moves, the limiting cylinder... 41 can limit the push block 120 by means of its relationship with the limit rod 4. After the liquid between the outer shell 1 and the stop block 12 evaporates naturally, it can be discharged through the ventilation slot 5 opened on the side wall of the outer shell 1. The protective cover 6 fixed to the side wall of the outer shell 1 can protect the regulating valve 16 and the gear 17 by itself and avoid external interference. At the same time, since the side wall of the protective cover 6 is provided with an exhaust hole 61, water vapor can be discharged through the exhaust hole 61. The outer shell 1, the fixed rod 11, the stop block 12 and the fixed sleeve 13 made of stainless steel can give full play to the advantages of high structural strength and strong oxidation resistance of stainless steel.
