[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0026] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0027] See also Figures 1 to 4 As shown, according to an embodiment of the present invention, a range hood is provided, including a range hood body 1, a fan is arranged in the range hood body 1, the range hood body 1 has an air outlet, the air outlet is located on the air outlet side of the fan, a filter assembly 2 is arranged at the air outlet, and a driving mechanism is also arranged in the range hood body 1, the driving mechanism can drive the filter assembly 2 to move out of the range hood body 1 and return to the range hood body 1.

[0028] In this technical solution, since a driving mechanism that cooperates with the filter assembly 2 is added to the range hood of the present application, the driving mechanism can drive the filter assembly 2 to move out of the range hood body 1 and return to the range hood body 1. Therefore, when replacing the filter in the filter assembly 2, the driving mechanism can drive the filter assembly 2 to move out of the range hood body 1, so that the operating space becomes spacious, which is not only more convenient when replacing the filter, but also because the operating space is relatively large, it is not easy to dirty the hands with oil on the filter. After the filter is replaced, it is only necessary to drive the filter assembly 2 back into the range hood body 1. Among them, the range hood of the present application can be a T-type range hood, a side-mounted range hood, etc.

[0029] See also Figure 3 As shown, the air outlet is formed at the top of the range hood body 1, or the air outlet is formed at the front of the range hood body 1 (not shown in the figure).

[0030] In this technical solution, when the air outlet is formed at the top of the range hood body 1, the fan in the range hood body 1 is for upward air outlet, which can circulate the air in the kitchen to improve the working environment of the kitchen. When the air outlet is formed at the front of the range hood body 1, the fan in the range hood body 1 is for front air outlet, which can not only circulate the air in the kitchen to improve the working environment of the kitchen, but also send air to the cooks to make them feel cool.

[0031] See also Figure 1 and Figure 2 As shown, the driving mechanism includes a telescopic component (not shown in the figure) and a folding frame 3, the folding frame 3 is connected to the telescopic component and the filter assembly 2 respectively, and the telescopic component drives the filter assembly 2 to move out of the range hood body 1 and return to the range hood body 1 through the folding frame 3.

[0032] In this embodiment, when the telescopic component drives the filter assembly 2 to move out of the range hood body 1 and back into the range hood body 1 through the folding frame 3, the movement of the filter assembly 2 can be made more stable. That is, the folding frame 3 plays a role in maintaining stable movement.

[0033] As a specific implementation, in the process that the telescopic component drives the filter assembly 2 to move out of the range hood body 1 and return to the range hood body 1 through the folding frame 3, the telescopic direction of the telescopic component is perpendicular to the movement direction of the filter assembly 2.

[0034] In this technical solution, the vertical space of the range hood body 1 is small and the horizontal space is large, so when the telescopic direction of the telescopic component is perpendicular to the movement direction of the filter assembly 2, the telescopic component can be arranged horizontally in the range hood body 1, so as to facilitate the installation of the telescopic component. The telescopic direction of the telescopic component is perpendicular to the movement direction of the filter assembly 2 mainly because the folding frame 3 is provided, and the folding frame 3 plays a role in converting the movement direction.

[0035] See also Figure 1 and Figure 2 As shown, the folding frame 3 includes a first bracket 31, a second bracket 32 ​​and a guide rail 33. The first bracket 31 is cross-connected with the second bracket 32, and the first bracket 31 and the second bracket 32 ​​can rotate relative to each other. The first end of the first bracket 31 is rotationally connected to the guide rail 33, the second end of the first bracket 31 is rotationally connected to the filter assembly 2, the first end of the second bracket 32 ​​is slidably connected to the guide rail 33, the second end of the second bracket 32 ​​is slidably connected to the filter assembly 2, and the telescopic component is connected to the first end of the second bracket 32.

[0036] In this embodiment, since the telescopic component is connected to the first end of the second bracket 32, when the telescopic component moves and retracts, the first end of the second bracket 32 ​​will slide along the guide rail 33, and the second end of the second bracket 32 ​​will also slide along the filter assembly 2, and the sliding directions of the first end and the second end of the second bracket 32 ​​are opposite, so the second bracket 32 ​​will be opened or retracted. At the same time, the second bracket 32 ​​will also drive the second bracket 32 ​​to be opened or retracted, so that the folding frame 3 is unfolded or retracted, and the filter assembly 2 is moved out of the range hood body 1 and returned to the range hood body 1. Among them, the telescopic component can be an electric push rod 7, a hydraulic cylinder, etc. It can be understood that since the two ends of the first bracket 31 are rotatably connected to the guide rail 33 and the filter assembly 2 respectively, in the process of the telescopic component driving the filter assembly 2 to move through the folding frame 3, only the two ends of the second bracket 32 ​​change their positions relative to the guide rail 33 and the filter assembly 2, while the two ends of the first bracket 31 remain in position relative to the guide rail 33 and the filter assembly 2. This ensures that the filter assembly 2 has a stable motion trajectory, thereby ensuring that the filter assembly 2 is accurately moved out of the range hood body 1 and returned to the range hood body 1.

[0037] It should be noted that, for the cross connection between the first bracket 31 and the second bracket 32, one of the first bracket 31 and the second bracket 32 ​​may be provided with a sleeve near the middle, and the other may be provided with a plug near the middle, and the plug can be rotatably inserted in the sleeve. For the first end of the first bracket 31 being rotatably connected to the guide rail 33, one of the first end of the first bracket 31 and the guide rail 33 may be provided with a sleeve, and the other may be provided with a plug, and the plug can be rotatably inserted in the sleeve. For the second end of the first bracket 31 being rotatably connected to the filter assembly 2, one of the second end of the first bracket 31 and the filter assembly 2 may be provided with a sleeve, and the other may be provided with a plug, and the plug can be rotatably inserted in the sleeve.

[0038] See also Figure 1 and Figure 2As shown, a first guide slot 4 is constructed on the guide rail 33 , and the extension direction of the first guide slot 4 is the same as the telescopic direction of the telescopic component. The first end of the second bracket 32 ​​has a first guide portion 34 , and the first guide portion 34 is slidably connected in the first guide slot 4 .

[0039] In this technical solution, the first guide portion 34 is slidably connected to the first guide slot 4 and has a guiding function, which can ensure that the first end of the second bracket 32 ​​slides on the guide rail 33 in the same direction as the telescopic direction of the telescopic component. The first guide portion 34 includes a connecting shaft at the first end of the second bracket 32 ​​and two flat plates at both ends of the connecting shaft, and the two flat plates are respectively in contact with the two side walls of the first guide slot 4. The two flat plates can increase the contact area between the first end of the second bracket 32 ​​and the two side walls of the first guide slot 4, so that the first end of the second bracket 32 ​​slides more smoothly along the first guide slot 4.

[0040] See also Figure 1 and Figure 2 As shown, a second guide slot 5 is constructed on the filter assembly 2, and the extension direction of the second guide slot 5 is parallel to the telescopic direction of the telescopic component. The second end of the second bracket 32 ​​has a second guide portion 35, and the second guide portion 35 is slidably connected in the second guide slot 5.

[0041] In this embodiment, the second guide portion 35 is slidably connected to the second guide slot 5 and has a guiding function, which can ensure that the second end of the second bracket 32 ​​slides on the filter assembly 2 in a direction parallel to the telescopic direction of the telescopic component. The filter assembly 2 includes a fixed frame and a filter screen, and the filter screen has a frame around it. The filter screen is detachably mounted on the fixed frame. When the filter assembly 2 is removed from the smoke machine body 1, the filter screen can be popped out of the fixed frame, so that it can be quickly replaced. The second guide slot 5 is provided on the side wall of the fixed frame, and the second guide portion 35 can be a plug rod formed at the second end of the second bracket 32, and the plug rod is slidably connected to the second guide slot 5.

[0042] See also Figure 1 and Figure 2 As shown, there are two driving mechanisms, and the two driving mechanisms can synchronously drive the filter assembly 2 from both sides to move out of the range hood body 1 and return to the range hood body 1 .

[0043] In this technical solution, by designing two driving mechanisms to drive the filter assembly 2 to move from both sides at the same time, it can be ensured that the forces on both sides of the filter assembly 2 are balanced during the movement, thereby making the movement of the filter assembly 2 more stable and the movement trajectory more accurate.

[0044] See also Figure 3As shown, at least two fans are arranged in the range hood main body 1, and the range hood main body 1 has at least two air outlets, each air outlet is located at the air outlet side of each fan, and a filter assembly 2 is arranged at each air outlet. At least two driving mechanisms are also arranged in the range hood main body 1, and each driving mechanism can drive each filter assembly 2 to move out of the range hood main body 1 and return to the range hood main body 1.

[0045] In this embodiment, the air circulation speed in the kitchen can be accelerated by increasing the number of fans in the range hood body 1 and the number of air outlets on the range hood body 1, thereby quickly improving the stuffy environment in the kitchen. At the same time, the filter assembly 2 arranged at each air outlet has a corresponding driving mechanism, so the filter on each filter assembly 2 is very easy to replace.

[0046] As a specific implementation, the filter assembly 2 is provided with an early warning monitoring device (not shown in the figure), which is used to monitor the dirtiness and blockage of the filter assembly 2 and issue an alarm when the dirtiness and blockage of the filter assembly 2 reaches a set degree.

[0047] In this technical solution, the early warning monitoring device is a combination of an air volume sensor and an alarm device. When the air volume sensor detects that the air volume per unit time on the filter assembly 2 is less than the set value, it will determine that the filter is seriously dirty and clogged, and thus send an electrical signal to the alarm device. After receiving the electrical signal, the alarm device will issue an alarm, thereby prompting the user to replace the filter.

[0048] Finally, it should be noted that the range hood further comprises a smoke exhaust duct 6 , which is fixed to the range hood body 1 .

[0049] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
