[0048] In summary, according to the fixing structure of the push rod of the utility model, by providing an inspection port 121 on the front plate 12, the fixing bracket 21 is connected to the rear plate 13 and aligned with the inspection port 121, and the connecting portion 222 of the push rod bracket 22 is connected to the fixing bracket 21. Then, when the electric push rod 3 fails and the telescopic panel 4 is hidden in the telescopic inner cavity, the screws connecting the connecting portion 222 and the fixing bracket 21 are removed through the inspection port 121, the electric push rod 3 is no longer limited, and the telescopic panel 4 is pulled forward, so that the telescopic panel 4 can be dragged forward, and the telescopic panel 4 no longer interferes with the cover plate, thereby facilitating the removal of the cover plate to repair the electric push rod 3 and the electrical components under the cover plate.

[0049] According to the second aspect of the present invention, the range hood is provided with a push rod fixing structure as in any one of the first aspect, and further, as Figure 3 and Figure 4 As shown, the housing 1 may further include a telescopic panel 4 and a transmission assembly 5.

Specifically, the telescopic inner cavity a can protect the equipment arranged in the telescopic inner cavity a, reduce the influence of smoke, water vapor, etc., and thus extend the service life of the equipment; further, the telescopic panel 4 is slidably connected to the telescopic inner cavity a, and connecting plates are connected to both sides of the telescopic panel 4; in this way, the telescopic panel 1 is fixed to the telescopic inner cavity a through the connecting plates; further, when it is applied to the range hood, when the range hood is working, the telescopic panel 4 slides out of the telescopic inner cavity a, so that the telescopic panel 4 reaches working position; when the user finishes cooking, the telescopic panel 4 retracts into the telescopic inner cavity a; further, the top plate 11 forms the bottom plate of the telescopic inner cavity a, so that the sealing of the bottom of the telescopic inner cavity a can be ensured by setting the top plate 11 at the bottom of the telescopic inner cavity a; further, the electric push rod 3 drives the telescopic panel 4 to slide in the telescopic inner cavity a through the transmission assembly 5; specifically, when the range hood is working, the electric push rod 3 drives the telescopic panel 4 to slide out in the telescopic inner cavity a through the transmission assembly 5; when the user finishes cooking, the electric push rod 3 drives the telescopic panel 4 to retract into the telescopic inner cavity a through the transmission assembly 5.

[0050] In the description of the present invention, a first feature being “above” or “below” a second feature may include that the first and second features are directly in contact with each other, or may include that the first and second features are not in direct contact but are in contact with each other via another feature therebetween.

[0051] Furthermore, if Figure 3 As shown, a front panel 6 may also be included. Furthermore, the front panel 6 covers the front plate 12 and is detachably connected to the shell 1. By arranging the front panel 6 on the side of the front plate 12 facing the user, the front plate 12 can be protected on the one hand, and the range hood can be easily maintained on the other hand.

[0052] Furthermore, if Figure 5As shown, the front panel 6 is provided with a first connecting member 61 and a second connecting member 62. Furthermore, the front panel 12 is provided with an installation port 122 symmetrical to the inspection port 121. In this way, the symmetrical arrangement of the inspection port 121 and the installation port 122 on the front panel 12 is conducive to improving the aesthetics of the structure of the front panel 12. In addition, the multiple utilizations of the front panel 12 can also be achieved. For example, in a specific embodiment, when the inspection port 121 is damaged, due to the symmetrical arrangement of the inspection port 121 and the installation port 122 on the front panel 12, the front panel 12 can be turned over, that is, the installation port 122 is used as the inspection port 121. In this way, the replacement of the front panel 12 due to damage of the inspection port 121 can be avoided, thereby improving the utilization rate of the structural parts. It should be noted that, in another specific embodiment, the inspection port 121 and the installation port 122 can also be asymmetrically arranged on the front panel 12, which will not be repeated here. Further, in a specific embodiment, the number of the first connecting members 61 is two, and the two first connecting members 61 are respectively connected to the front panel 12 through the inspection port 121 and the installation port 122, thereby ensuring the firmness of the connection between the upper part of the front panel 6 and the front panel 12; further, the second connecting member 62 is connected to the lower edge of the front panel 6 and connected to the rear panel 13, thereby ensuring the firmness of the connection between the lower part of the front panel 6 and the rear panel 13. It should be noted that, in another specific embodiment, the number of the first connecting members 61 can also be other numbers, which will not be repeated here.

[0053] In the description of the present invention, a first feature “above”, “over” and “above” a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature.

In this way, the position of the second connecting rod 52 can be adjusted by the synchronization shaft 54, so that the extension lengths of both sides of the telescopic panel 4 when moving in the telescopic inner cavity a can be made consistent, so as to avoid the deflection of the telescopic panel 4 in the telescopic inner cavity a, which affects the extension or retraction of the telescopic panel 4 into the telescopic inner cavity a. Further, the driving end of the electric push rod 3 is connected to the first end of the first connecting rod 51, and the second end of the first connecting rod 51 is connected to the synchronization shaft 54. The synchronization shaft 54 ​​can realize the synchronization of the two sides of the telescopic panel 4 when extending or retracting into the telescopic inner cavity a.

[0056] Furthermore, when the first connecting rod 51 and the second connecting rod 52 make linear movement, the moving direction of the first connecting rod 51 and the second connecting rod 52 is the same as the moving direction of the driving end of the electric push rod 3; in this way, when the first connecting rod 51 and the second connecting rod 52 make linear movement, the telescopic panel 4 can be driven to move between the starting position and the end position of the linear movement position, and by setting the moving direction of the first connecting rod 51 and the second connecting rod 52 to be the same as the moving direction of the driving end of the electric push rod 3, it can be ensured that the movement of the telescopic panel 4 is consistent with the moving direction of the first connecting rod 51, the second connecting rod 52 and the electric push rod 3, thereby ensuring that the telescopic panel 4 can be normally extended or retracted in the telescopic inner cavity a.

[0057] Furthermore, guide assemblies 7 are provided on both sides of the telescopic inner cavity a. Specifically, guide assemblies 7 are provided on the left and right walls of the telescopic inner cavity a.

[0058] Furthermore, in a specific embodiment, a slide groove is provided on the fixed rail 71, and further, slide bars are provided on the upper and lower sides of the movable rail 72, and the slide bars are slidably connected in the slide groove. In this way, through the cooperation of the slide bar and the slide groove, the movable rail 72 and the fixed rail 71 can be slidably cooperated, thereby providing a guide for the sliding of the telescopic panel 4 in the telescopic inner cavity a, so that the telescopic panel 4 can slide along a predetermined route in the telescopic inner cavity a.

[0059] Furthermore, in a specific embodiment, a plurality of sliders are provided on the slide bar, and the slide bar is slidably connected in the slide groove, and further, the slider is slidably connected to the wall surface of the slide groove on the corresponding side; in this way, the movable rail 72 and the fixed rail 71 can be slidably connected by the sliding connection between the slider and the wall surface of the slide groove on the corresponding side, so as to realize the coordinated sliding of the movable rail 72 and the fixed rail 71, thereby providing a guiding effect for the sliding of the telescopic panel 4 in the telescopic inner cavity a, so that the telescopic panel 4 can slide along a predetermined route in the telescopic inner cavity a.

[0060] In summary, the range hood according to the second aspect of the present invention is provided with a push rod fixing structure as in any one of the first aspect, so that when the electric push rod 3 fails and the telescopic panel 4 is hidden in the telescopic inner cavity, the cover plate can be removed through the provided inspection port 121 to facilitate maintenance of the electric push rod 3 and the electrical components under the cover plate.
