[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0025] Please refer to 1-5, an integrated hood includes: a foot ring 1, a movable part is movably sleeved on the foot ring 1, a rubber sleeve 9 is fixedly connected to the bottom of the foot ring 1, a second support frame 7 is fixedly connected inside the foot ring 1, a cross groove 71 is opened in the second support frame 7, a plurality of abutment members are slidably arranged in the cross groove 71, and the ends of the abutment members abut on the rubber sleeve 9.

[0026] Specifically, the utility model inserts the bottom of the foot ring 1 into the vent, and abuts the rubber sleeve 9 against the inner wall of the vent by sliding the abutment piece in the cross groove 71, so that the hood is locked in the vent as a whole, thus avoiding the additional work of drilling holes to install the hood and facilitating the inspection and replacement of the hood.

[0027] Furthermore, a support rod 2 is inserted into the cross groove 71 , a wedge ring 22 is fixedly sleeved on the outer side of the support rod 2 , a plurality of wedge blocks 72 are slidably arranged in the cross groove 71 , and the wedge blocks 72 are connected to the abutment member via a spring 73 .

[0028] Specifically, one end of the spring 73 is fixedly connected to the wedge block 72, and the other end is fixedly connected to the abutment. By sliding the support rod 2 up and down, the wedge ring 22 is driven to abut against multiple wedge blocks 72, and then the spring 73 is squeezed, so that the spring 73 is compressed and has an elastic force. The elastic force of the spring 73 squeezes the abutment to slide, and the abutment is pressed against the rubber sleeve 9, thereby locking the foot ring 1 and the vent.

[0029] Furthermore, the abutment member includes a slider 74 and an abutment plate 75 . The slider 74 is slidably disposed in the cross groove 71 . One end of the abutment plate 75 is fixedly connected to one end of the slider 74 passing through the second support frame 7 , and the other end of the abutment plate 75 abuts on the rubber sleeve 9 .

[0030] Specifically, the slider 74 is T-shaped and is restricted to slide in the cross groove 71. One end of the abutment plate 75 abutting the rubber sleeve 9 is an arc block, which increases the contact area between the abutment plate 75 and the rubber sleeve 9 as much as possible, thereby increasing the locking stability between them.

[0031] Furthermore, the movable part includes a middle ring 8 and a cap top 3 , the middle ring 8 is movably sleeved on the foot ring 1 , and the blade group 4 is detachably connected between the middle ring 8 and the cap top 3 .

[0032] Specifically, the blade group 4 is composed of a plurality of blades, and the blades are fixed to the cap top 3 and the middle ring 8 by rivets.

[0033] Furthermore, a first support frame 6 is disposed in the middle circle 8 , and the first support frame 6 is connected to the support rod 2 via a second bearing 61 .

[0034] Specifically, the first support frame 6 is riveted to the middle ring 8, and the inner ring of the second bearing 61 is fixedly sleeved on the support rod 2, and the outer ring of the second bearing 61 is embedded in the first support frame 6. The stability of the movable part is increased by setting the first support frame 6.

[0035] Furthermore, a threaded sleeve 5 is externally threadedly connected to the top of the support rod 2 , and the threaded sleeve 5 is connected to the cap top 3 via a first bearing 53 .

[0036] Specifically, the outer ring of the first bearing 53 is fixedly connected to the cap top 3, and the inner ring of the first bearing 53 is fixedly sleeved on the screw sleeve 5. When the screw sleeve 5 is turned, the screw sleeve 5 rotates in place, and the support rod 2 moves in the vertical direction to achieve the installation locking of the hood.

[0037] Furthermore, a through hole 52 is formed in the screw sleeve 5 , a straight notch 21 is formed on the top of the support rod 2 , a waterproof sticker 51 is pasted on the top of the screw sleeve 5 , and the waterproof sticker 51 is located directly above the through hole 52 .

[0038] Specifically, by opening a through hole 52 on the screw sleeve 5 and a straight groove 21 on the top of the support rod 2, it is possible to limit the support rod 2 with a screwdriver during installation, thereby rotating the screw sleeve 5 to achieve vertical movement of the support rod 2. The waterproof sticker 51 attached to the screw sleeve 5 is to prevent rainwater from entering the screw sleeve 5 and corroding the screw sleeve 5 and the support rod 2.

[0039] In this utility model, reference is made to Figures 1 to 5 , the assembly method of the hood is as follows:

[0040] First, install the wedge block 72, spring 73, and abutment into the second support frame 7, then fix the second support frame 7 on the foot ring 1, and install the rubber sleeve 9 on the foot ring 1 by means of snap connection or rivet locking. Then, pass the support rod 2 with the wedge ring 22 into the second support frame 7 from the lower side of the foot ring 1, and then sleeve the middle ring 8 on the outside of the foot ring 1. At the same time, fix the first support frame 6 on the support rod 2 through the second bearing 61, and lock the two ends of the first support frame 6 on the middle ring 8 by rivets. Then, connect the cap top 3 and the screw sleeve 5 through the bearing, and spirally connect the support rod 2 and the screw sleeve 5. Finally, nail the two ends of the blade group 4 to the cap top 3 and the middle ring 8 by rivets to complete the assembly of the hood.

[0041] In this utility model, reference is made to Figures 1 to 5 The installation method of the hood is as follows: first, put the foot ring 1 and the rubber sleeve 9 into the vent, then the foot ring 1 is clamped on the vent, and the screw sleeve 5 is screwed to make the support rod 2 slide downward in the screw sleeve 5, and then drive the middle ring 8 to clamp into the smooth protrusion on the outside of the foot ring 1, and the limited middle ring 8 can only rotate on the same horizontal plane outside the foot ring 1. In the prior art, the middle ring 8 and the foot ring 1 are rotatably connected, and a groove is provided in the middle ring 8. A smooth protrusion is provided on the outside of the foot ring 1. The limited connection between the groove and the protrusion is adopted. On the one hand, it can be limited, and on the other hand, it does not affect the rotation. At the same time, the wedge ring 22 squeezes the wedge block 72, so that the wedge block 72 overcomes the elastic force of the spring 73 and slides outward, and then the spring 73 is in a compressed state, and the elastic force of the spring 73 squeezes the wedge block 72 and the abutment, and then the rubber sleeve 9 is tightly locked in the vent, that is, the hood is locked in the vent.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
