[0038] Embodiment 1

[0039] As Figure 1 - Figure 5 shown, the sliding structure provided by the present utility model includes: a fixed outer shell 1, a movable inner shell 2, a slide rail 3, and a boss 4. The fixed outer shell 1 has a first assembly surface 5.

[0040] As Figure 1 shown, the fixed outer shell 1 is fixedly connected to the wall surface of the kitchen. The movable inner shell 2 is located inside the fixed outer shell 1. The movable inner shell 2 is connected to the fixed outer shell 1 through the slide rail 3 to achieve free up and down movement. And a lead screw motor 11 is provided on the fixed outer shell 1. The transmission part of the lead screw motor 11 is connected to the movable inner shell 2 to drive the movable inner shell 2 to lift.

[0041] The slide rail 3 includes a fixed part and a sliding part that are slidably connected, which are existing structural parts in the prior art. The sliding part is connected to the movable inner shell 2.

[0042] As Figure 3 and Figure 4As shown, the boss 4 is connected between the first assembly surface 5 and the fixing part, and is used to lift the fixing part of the slide rail 3 so that the fixing part is spaced from the first assembly surface 5. After the lifting range hood works for a period of time, the oil stains on the fixed housing 1 will condense into droplets and gradually flow downward along the inner wall of the fixed housing 1. When it flows to the position of the boss 4, it will be blocked by the boss 4, so that it will not flow into the fixing part, avoiding oil stains from entering the inside of the slide rail 3 and affecting its normal operation. The minimum distance D between the first assembly surface 5 and the fixing part is greater than or equal to 4 mm, preferably 5 mm.

[0043] As Figure 4 shown, a support platform 6 is provided on the fixed housing 1. The support platform 6 includes two first assembly surfaces 5 extending vertically and arranged at an angle. A boss 4 and a slide rail 3 are provided on each first assembly surface 5.

[0044] The support platform 6 extends in the up and down direction, and the shape of its cross section can be trapezoidal or triangular. The surface of the support platform 6 facing the front is formed by two first assembly surfaces 5 arranged at an angle. One slide rail 3 can be provided on each first assembly surface 5 to improve the running stability.

[0045] The angle between the two first assembly surfaces 5 on the support platform 6 can be 90°, and the two slide rails 3 will also form a 90° angle. Of course, the angle between the two first assembly surfaces 5 can also be other angles, such as 80° or 120°, etc.

[0046] The bosses 4 on the two first assembly surfaces 5 on the support platform 6 are connected into an integral structure, which can reduce the number of installations. During installation, connect the integral structure to the support platform 6, and only one connection is required to complete the fixation of the two bosses 4.

[0047] As Figure 3 and Figure 4 shown, a groove 21 is provided on the movable inner shell 2. A slide rail fixing frame 7 is connected to the inner wall of the groove 21. The slide rail fixing frame 7 includes two second assembly surfaces 71 extending vertically and arranged at an angle. One of the two second assembly surfaces 71 is connected to the sliding part of one of the two slide rails 3 on the support platform 6, and the other of the two second assembly surfaces 71 is connected to the sliding part of the other of the two slide rails 3 on the support platform 6.

[0048] The groove 21 on the movable inner shell 2 is in concave-convex correspondence with the support platform 6, so as to avoid the distance between the inner wall of the fixed housing 1 and the outer wall of the movable inner shell 2 from being too far. The slide rail fixing frame 7 has two perpendicular arms, and the two second assembly surfaces 71 are respectively provided on the two arms. The two arms are respectively attached to and connected to the two side surfaces of the groove 21. The slide rail fixing frame 7 plays a strengthening role, and its material can be different from that of the movable inner shell 2. The slide rail fixing frame 7 has higher strength.

[0049] AsFigure 2 As shown, the number of the supporting platforms 6 is at least two. The sliding structure includes a reinforcing frame 8 which is arranged horizontally. At least two supporting platforms 6 are connected to the reinforcing frame 8, and the reinforcing frame 8 connects each supporting platform 6 together, increasing the stability.

[0050] As Figure 1 shown, the upper ends of the respective supporting platforms 6 are connected by an upper support plate 9, and the lower ends of the respective supporting platforms 6 are connected by a lower support plate 10. The reinforcing frame 8 is located between the upper support plate 9 and the lower support plate 10.

[0051] Embodiment 2

[0052] As Figure 6 shown, the difference from Embodiment 1 is that the top surface of the convex platform 4 in Embodiment 1 is a plane, while in this embodiment, the top surface 14 of the convex platform 4 is an inclined surface. From top to bottom, the inclined surface inclines towards the first assembly surface 5. After the oil stain left on the first assembly surface 5 from top to bottom flows to the top surface 14 of the convex platform 4, it is blocked by the inclined surface and will not flow forward, but will flow out from the left and right sides of the top surface 14 and continue to flow downward.

[0053] Embodiment 3

[0054] As Figure 7 shown, the difference from Embodiment 1 is that in this embodiment, the top of the convex platform 4 has a guiding portion, and the guiding portion includes a first guiding inclined surface 12 and a second guiding inclined surface 13 respectively located on the left and right sides of the convex platform 4. The top ends of the first guiding inclined surface 12 and the second guiding inclined surface 13 intersect, and from top to bottom, the distance between the first guiding inclined surface 12 and the second guiding inclined surface 13 in the left - right direction gradually increases.

[0055] The cross - sectional shape of the guiding portion can be triangular, and the cross - section is perpendicular to the front - back direction. The first guiding inclined surface 12 and the second guiding inclined surface 13 on the left and right sides of the guiding portion form an oil - guiding surface, guiding the oil stain to flow towards the left and right sides of the convex platform 4, thereby further reducing the oil stain flowing towards the fixing portion.

[0056] The lifting range hood provided by the present utility model includes the above - mentioned sliding structure. Because the lifting range hood provided by the present utility model incorporates the above - mentioned sliding structure, the lifting range hood provided by the present utility model also has the advantages of the sliding structure.

[0057] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
