To make the objectives, solutions, and beneficial effects of this application clearer, the following further describes this application with reference to the accompanying drawings and preferred embodiments. Some accompanying drawings may not be accurate enough. In this case, this application shall be subject to the text descriptions. Embodiment 1
This application provides an embodiment of a range hood. The range hood is provided with a chassis 1 , a blower, and a housing assembly, as shown in FIG. 1 and FIG. 2. The range hood is a ceiling-mount range hood and is in a shape of an inverted T. The blower is disposed in the chassis 1. The housing assembly includes a housing member and a telescopic member. In this embodiment, the housing member refers to a fume collecting hood 2. The chassis 1 is connected to the fume collecting hood 2, and the chassis 1 is located above the fume collecting hood 2. The fume collecting hood 2 is provided with an air inlet connected to the blower. A surface that is of the fume collecting hood 2 and that is set downwardly is a fume guiding surface, and is used for guiding the air to flow into the air inlet and then flow into the blower.
The telescopic member includes an end head 4, a bouncing rod 5, a damper 6, and a rebounder 14, as shown in FIG. 3. The end head 4 is in a shape of a cylinder, and a top wall 13 of the end head 4 is a round plane. A side wall 12 of the end head 4 is provided with an accommodation hole. The telescopic member is provided with a camera 3, and the camera 3 is disposed in the accommodation hole of the side wall 12 of the end head 4.
An accommodation chamber is disposed on the fume guiding surface of the fume collecting hood 2, and the telescopic member is fixed in the accommodation chamber, as shown in FIG. 1 and FIG. 2. The telescopic member is set to be capable of switching between an extension location and a contraction location. That is, there are two locations for the telescopic member to remain: the extension location and the contraction location. When the telescopic member is located at the extension location, the camera 3 is placed out of the accommodation chamber, as shown in FIG. 2 and FIG. 5. In this case, the camera 3 can implement functions such as photographing, video recording, or human face recognizing. When the telescopic member is located at the contraction location, the camera 3 is hidden in the accommodation chamber, and a user cannot view the camera 3, as shown in FIG. 1 and FIG. 4. When the telescopic member is located at the contraction location, the camera 3 is blocked by the fume collecting hood 2 in a horizontal direction, and only the top wall 13 of the end head 4 of the telescopic member is visible. In this case, the end head 4 of the top wall 13 is joined to the fume collecting hood 2 of the fume guiding surface.
When the telescopic member switches between the extension location and the contraction location, the telescopic member moves along a vertical direction. The damper 6 is set to be configured to alleviate movement of the telescopic member when the telescopic member moves along the vertical direction. Specifically, the damper 6 acts on the bouncing rod 5, as shown in FIG. 3.
The telescopic member is set to be configured to switch between the extension location and the contraction location in a manner of pressing the top wall 13 of the end head 4 of the telescopic member. When the telescopic member is located at the contraction location, if the user presses the top wall 13 of the end head 4 along an arrow direction in FIG. 1 and FIG. 4 by using a finger and then moves the finger away, the bouncing rod 5 is bounced by the rebounder 14, and the bouncing rod 5 moves downward along an extension direction of the bouncing rod 5. The bouncing rod 5 drives the camera 3 to extend out of the accommodation chamber, and the telescopic member switches to the extension location. When the telescopic member is located at the extension location, if the user presses the top wall 13 of the end head 4 along an arrow direction in FIG. 2 and FIG. 5 by using the finger until the bouncing rod 5 is locked by the rebounder 14 at the location shown in FIG. 4, and then moves the finger away the telescopic member remains at the contraction location shown in FIG. 4. In this case, the camera 3 is hidden in the accommodation chamber. The arrow direction shown in FIG. 3 is the direction in which the top wall 13 of the end head 4 is pressed. One end of the bouncing rod 5 cooperates with the rebounder 14, and the other end is connected to the end head 4, as shown in FIG. 3 to FIG. 5. Specifically, the other end of the bouncing rod 5 (that is, the end that is of the bouncing rod 5 and that connects to the end head 4) is provided with an expansion head 7, and the end head 4 is provided with a narrow-mouthed accommodation groove 8 cooperated with the expansion head 7, as shown in FIG. 4 and FIG. 5. The expansion head 7 is disposed in the narrow-mouthed accommodation groove 8, and the expansion head 7 may rotate in the narrow-mouthed accommodation groove 8. However, in a state in which the range hood is normally used, the expansion head 7 cannot withdraw from the narrow-mouthed accommodation groove 8. Because a structure in which the expansion head 7 cooperates with the narrow- mouthed accommodation groove 8 is adopted, when the telescopic member is located at the extension location, the end head 4 is configured to rotate about an axis of the cylinder- shaped end head 4 under the action of manpower of the user (for example, the user uses a finger to rotate the end head 4), to adjust a shooting angle of the camera 3. Specifically, the shooting angle of the camera 3 may rotate by 360 degrees.
The foregoing is merely a preferred embodiment of this application, and other embodiments may further be obtained by performing addition, deletion, modification, or replacement on some technical features. For example, the housing assembly for the range hood may be the housing member provided with the accommodation chamber, or may be the chassis or a control panel, or the like. For another example, the rebounder may alternatively be replaced by another existing component that can implement the same functions and effects. For another example, it may alternatively be that the telescopic member further includes an electric-powered apparatus. The end head is rotated by using the electric-powered apparatus, to adjust the shooting angle of the camera. Here, "the electric-powered apparatus" may be understood as an apparatus that can convert electric energy into particular mechanical motion, for example, a motor drive apparatus. For another example, it may alternatively be that a degree by which the camera extends out of the accommodation chamber may be set to be adjustable. For another example, the solution of the housing assembly for the range hood provided in this application may alternatively be applied to an inclined range hood.
Embodiment 2 This application further provides Embodiment 2 of another range hood. Embodiment
2 of the range hood is obtained based on further improvement of Embodiment 1 of the foregoing range hood. The main differences between Embodiment 2 of the range hood and Embodiment 1 of the foregoing range hood are as follows: A telescopic member in Embodiment 2 of the range hood includes an electric- powered apparatus. The telescopic member is controlled, by using the electric-powered apparatus, to switch between an extension location and a contraction location. Specifically, the electric-powered apparatus includes a motor 9, a worm wheel 10, and a worm 11 , as shown in FIG. 6. The worm 1 1 is connected to an end head 4 of the telescopic member. Both the worm wheel 10 and the worm 1 1 are provided with teeth (not shown), and the worm wheel 10 is engaged with the worm 1 1. The motor 9 drives the worm wheel 10 to rotate, and the worm wheel 10 drives the worm 1 1 to perform rectilinear motion along an arrow direction in FIG. 6, to control the telescopic member to switch between the extension location and the contraction location. For another structure and cooperation relationship of Embodiment 2 of the range hood, refer to the corresponding descriptions in Embodiment 1 of the range hood.
Embodiment 3
This application further provides Embodiment 3 of another range hood. Embodiment
3 of the range hood is obtained based on further improvement of Embodiment 1 of the foregoing range hood. The main differences between Embodiment 3 of the range hood and Embodiment 1 of the foregoing range hood are as follows:
An end that is of a bouncing rod 5 in Embodiment 3 of the range hood and that connects to an end head 4 is provided with a narrow-mouthed accommodation groove 8, and the end head 4 is provided with an expansion head 7 cooperating with the narrow- mouthed accommodation groove 8 of the bouncing rod 5, as shown in FIG. 7 and FIG. 8. The expansion head 7 of the end head 4 is disposed in the narrow-mouthed accommodation groove 8 of the bouncing rod 5, and the expansion head 7 may rotate in the narrow-mouthed accommodation groove 8. However, in a state in which the range hood is normally used, the expansion head 7 cannot withdraw from the narrow-mouthed accommodation groove 8. Because a structure in which the expansion head 7 cooperates with the narrow-mouthed accommodation groove 8 is adopted, when the telescopic member is located at the extension location, the end head 4 is configured to rotate about an axis of the cylinder-shaped end head 4 under the action of manpower of the user, to adjust a shooting angle of the camera 3.
