[0033] like Figure 1-2 As shown, in one embodiment, a window opener 10 is provided, which includes an outer tube 1, a waterproof tube 2, a transmission assembly 3 and a drive assembly 4.

[0034] The outer tube 1 is provided with a chain opening 11 .

[0035] The outer tube 1 includes a first tube body 12 and first end covers 13 disposed at both ends of the first tube body 12, the chain opening 11 is disposed in the first tube body 12, and the waterproof tube 2, the mounting seat 31 and the chain 34 are respectively disposed in the first tube body 12. When the waterproof tube 2, the mounting seat 31 and the chain 34 need to be disassembled, it is only necessary to open the first end cover 13, which is simple and convenient, thereby improving the disassembly efficiency of the window opener 10.

[0036] The outer tube 1 further includes a first waterproof ring 14 disposed between the first tube body 12 and the first end cover 13. The first waterproof ring 14 can prevent water outside the first tube body 12 from entering the first tube body 12 through the gap between the first tube body 12 and the first end cover 13, thereby improving the waterproofness of the outer tube 1.

[0037] The first waterproof ring 14 is made of rubber material. Since the rubber material has good elasticity, by pressing the first tube body 12 and the first end cover 13 tightly, it is difficult for a gap to exist between the two, thereby further improving the waterproofness of the outer tube 1.

[0038] The waterproof tube 2 is arranged inside the outer tube 1 .

[0039] The waterproof tube 2 includes a second tube body 21 and a second end cap 22 covering one end of the second tube body 21, and the driving assembly 4 is disposed in the second tube body 21. When the driving assembly 4 needs to be disassembled, it is only necessary to open the second end cap 22, which is simple and convenient, thereby improving the disassembly efficiency of the window opener 10.

[0040] The waterproof tube 2 also includes a second waterproof ring 23 disposed between the second tube body 21 and the second end cover 22. The second waterproof ring 23 can prevent water outside the second tube body 21 from entering the second tube body 21 through the gap between the second tube body 21 and the second end cover 22, thereby improving the waterproofness of the waterproof tube 2.

[0041] The second waterproof ring 23 is made of rubber material. Since the rubber material has good elasticity, by pressing the second tube body 21 and the second end cover 22 tightly, it is difficult for a gap to exist between the two, thereby further improving the waterproof performance of the waterproof tube 2.

[0042] The transmission assembly 3 includes a mounting seat 31, a gear 32, a sprocket 33 and a chain 34 arranged in the outer tube 1. The gear 32 and the sprocket 33 are rotatably arranged in the mounting seat 31 respectively, the gear 32 and the sprocket 33 are meshingly connected, the sprocket 33 and the chain 34 are transmission connected, and one end of the chain 34 passes through the chain mouth 11 and is connected to the window.

[0043] The transmission assembly 3 also includes a chain guide box 35 disposed in the outer tube 1, and the chain guide box 35 is used to guide the movement of the chain 34 so that the chain 34 can move regularly along a preset direction to avoid the chain 34 from getting entangled during movement, thereby improving the reliability of the movement of the chain 34.

[0044] The transmission assembly 3 also includes a meshing worm (not shown) and a worm wheel 36, the worm is connected to the driving assembly 4, the worm wheel 36 is rotatably disposed in the mounting seat 31, and the worm wheel 36 is meshingly connected to the gear 32. The power between the two staggered axes can be transmitted by the worm and the worm wheel 36, which can not only obtain a larger transmission ratio but also a more compact structure compared to the staggered axis helical gear 32. Since the meshing tooth surfaces of the worm and the worm wheel 36 are in line contact, a larger bearing capacity can be obtained compared to the staggered axis helical gear 32.

[0045] The driving assembly 4 is arranged in the waterproof tube 2, and the driving assembly 4 is used to drive the gear 32 to rotate, so that the gear 32 drives the sprocket 33 to rotate, and the sprocket 33 drives the chain 34 to move, so that the chain 34 drives the window to close or open. Through the newly added waterproof tube 2, the driving assembly 4 inside can effectively isolate the water entering from the outer tube 1, so that the driving assembly 4 can be in a dry environment, thereby avoiding the phenomenon of short circuit of the driving assembly 4, thereby improving the safety of the window opener 10.

[0046] The driving assembly 4 includes a circuit board 41, a driving member 42, a wire element 43 and a waterproof wire tube 44. The wire element 43 includes a first wire and a second wire 431. The waterproof wire tube 44 is sleeved on the second wire 431. The waterproof tube 2 is provided with a wire hole (not shown in the figure). The waterproof wire tube 44 is inserted into the wire hole. One end of the circuit board 41 is connected to the driving member 42 through the first wire, and the other end is connected to the external power supply through the second wire 431. The circuit board 41 and the driving member 42 are respectively arranged in the waterproof tube 2, and the driving member 42 is used to drive the gear 32 to rotate. Since the waterproof wire tube 44 and the hole wall of the wire hole can be in closer contact, it is not easy for external water to enter the waterproof tube 2 through the gap between the waterproof wire tube 44 and the hole wall of the wire hole, thereby improving the waterproofness of the waterproof tube 2. Specifically, the wire hole is provided with a second end cap 22, the circuit board 41 and the driving member 42 are respectively arranged in the second tube body 21, and the driving member 42 is a motor.

[0047] Working principle:

[0048] The driving member 42 drives the worm to rotate, the worm drives the turbine to rotate, the turbine drives the gear 32 to rotate, the gear 32 drives the sprocket 33 to rotate, when the sprocket 33 rotates clockwise, the sprocket 33 drives the chain 34 in the chain box to extend from the chain opening 11, so as to open the window. When the sprocket 33 rotates counterclockwise, the sprocket 33 drives the chain 34 from the chain opening 11 into the chain box, so as to close the window.

[0049] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
