Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1 to 2, a range hood, which is a ceiling range hood, includes a fan frame 4 and a fan 1 disposed inside the fan frame 4, where the fan 1 includes a volute 11.

Referring to fig. 2 and 3, a fan fixing device for fixing the fan 1 is provided at an inner side of the fan frame 4. In the present embodiment, the air inlet of the fan 1 faces the front side and/or the rear side. The fan fixing device comprises a fixing piece 2 arranged along the left and right direction of the fan frame 4, namely the extending direction of the fixing piece 2 is vertical to the axial direction of the fan 1. The fixing member 2 includes a housing 21, and both ends of the housing 21 in the length direction (left-right direction) are connected to the inner sides of the corresponding sides of the left and right sides of the fan frame 4, respectively. The fan fixing device also comprises a bracket 3 used for being connected with the fan 1. The support 3 is in a strip shape, the support 3 is arranged on the front side of the volute casing 11, can be connected to the volute casing 11 through welding or screws, and is used for supporting the volute casing 11 in a fixed state of the volute casing 11.

Referring to fig. 3 to 5, the fixing member 2 further includes a cover plate 22, a slider 24, and an elastic member 26, and the cover plate 22 and the housing 21 are engaged with each other such that an accommodating space is formed between the housing 21 and the cover plate 22. The bracket 3 is arranged on the side of the cover plate 22 remote from the housing 21. The slide blocks 24 are provided with two slide blocks 24, each slide block 24 corresponds to one elastic piece 26, and the elastic pieces 26 are arranged in the accommodating space. The first sliding groove 214 is formed at a position of the housing 21 near each end in the length direction, the first sliding groove 214 penetrates through the wall thickness of the housing 21, and the second sliding groove 223 is formed at a position of the cover plate 22 near each end in the length direction. The first slide groove 214 and the corresponding second slide groove 223 correspond in position and are identical in shape. To facilitate the engagement of the slider 24 with the first sliding groove 214, a pin 243 extending forward to penetrate the first sliding groove 214 may be provided at the front side of the slider body 241, and the pin 243 slides along the first sliding groove 214.

A distance between corresponding ends (e.g., upper ends) of the two first sliding grooves 214 (i.e., a distance between center positions of the end portions of the two first sliding grooves 214) is a, a distance between other corresponding positions of the two first sliding grooves 214 (i.e., a distance between centers of corresponding positions of the two first sliding grooves 214) is not less than a, and a maximum distance between other corresponding positions of the two first sliding grooves 214 is b, which may be located in the middle of each first sliding groove 214. Preferably, the distance between the corresponding other ends (lower ends) of the two first sliding grooves 214 is smaller than b, and more preferably is also a. In the present embodiment, each first sliding groove 214 is in an arc shape protruding toward the corresponding end in the length direction of the housing 21, and the distance between the other ends of the two first sliding grooves 214 is also preferably a, i.e., the distances between the corresponding ends of the two first sliding grooves 214 are equal.

A baffle 28 is disposed in the receiving space, such as the middle of the cover plate 22, and each elastic member 26 is connected between the baffle 28 and the corresponding slider 24. In this embodiment, the elastic member 26 is preferably a spring, and both ends thereof are connected to the stopper 28 and the slider 24, respectively. When the distance between the sliders 24 is minimal, the elastic member 26 is in tension, so that the two sliders 24 tend to remain close to each other; when the sliders 24 move away from each other, the elastic member 26 gradually expands to continue to increase the tension, pushing the sliders 24 gradually away. The elastic member 26 provides a preload to the slider 24. The distance between the corresponding ends of the two first sliding grooves 214 is only required to be such that the elastic member 26 is always in a stretched state.

The two sliders 24 can be manually slid along the first sliding groove 214 (the second sliding groove 223) so as to be able to move toward or away from each other, thereby clamping the bracket 3 when the two sliders 24 are close and releasing the bracket 3 when the two sliders 24 are away. The bracket 3 may be connected to the volute 11 by welding or screws.

Referring to fig. 6, the slider 24 may be in a stable state at an upper end of the first slide groove 214 (the second slide groove 223) and a lower end of the first slide groove 214 (the second slide groove 223), respectively. The end of the elastic element 26 connected to the stop 28 is fixed at point O, which points a/B correspond to the two stable positions of the slider 24. The two positions are the intersection of two circles. The slider 24 moves along an arc between points a-B in the figure under the action of the first sliding chute 214 (the second sliding chute 223). It can be seen that, on the motion locus, the lengths of the elastic elements 26 at the points a and B are equal and shortest, and the lengths of the elastic elements 26 at other points are all greater than those at the points a/B, that is, D1 (the length of the connecting line between a and O) < D2 (the length of the connecting line between B and O) < D3 (the length of the connecting line between other points on the arc and O). The slider 24 will always be clamped at point a or B.

The slider 24 includes a slider body 241 connected to the link assembly 23, a snap joint 242 provided on the slider body 241 for snap-fitting with the bayonet 31 of the bracket 3, and a pin 243 slidably fitted with the first slide groove 214. The slider body 241 is disposed between the housing 21 and the cover plate 22, and the latch 242 is inserted through the second slide groove 223 of the cover plate 22 to be engaged with the bracket 3. The holder 3 has bayonets 31 formed at both ends in the left-right direction, which are recessed from the end surfaces toward the inside (recessed from both ends toward the middle), respectively, and which engage with the sliders 24.

Referring to fig. 2 and 3, when the range hood needs to be moved and transported, and the volute 11 needs to be fixed on the fan fixing device, the slider 24 is placed at a position (in this embodiment, the upper end) with the minimum distance between the two first sliding grooves 214, at this time, the clamping head 242 of the slider 24 is clamped with the bayonet 31 of the bracket 3, and the volute 11 enters a fixed state, so that the range hood is prevented from being deformed due to vibration and other reasons during transportation to cause abnormal performance or structure of the range hood.

Referring to fig. 7 and 8, when the range hood needs to be used and the volute 11 needs to be loosened from the fan fixing device, the sliding blocks 24 are manually moved downward along the first sliding groove 214 (the second sliding groove 223), the distance between the two sliding blocks 24 is gradually increased until the clamping head 242 of the sliding block 24 is separated from the bayonet 31 of the bracket 3, so that the volute 11 is suspended, and the volute 11 enters a free state, thereby preventing the vibration from being transmitted to the fan frame 4 to cause the resonance of the whole range hood when the fan 1 runs. In the above process, since the first sliding groove 214 (the second sliding groove 223) is arc-shaped, when the sliding block 24 slides to the position with the maximum position, and the hand is released at this time, the sliding block 24 automatically slides downwards under the action of the elastic piece 26 until the sliding block slides to the lower end of the first sliding groove 214 (the second sliding groove 223), that is, the sliding block 24 is in a suspended state corresponding to the volute 11, and at this time, the sliding block 24 can be kept in a stable state without applying force to the sliding block 24, which is convenient for the operation of detaching the fan 1.
