[0029] Referring to Figures 1 to 5 The utility model discloses a cabinet bottom oil fume exhauster's mounting structure, include: smoke machine main body 100, the top of smoke machine main body 100 is equipped with at least two hanger rod subassembly 200, at least two hanger rod subassembly 200 is along the length direction interval arrangement of smoke machine main body 100, hanger rod subassembly 200 includes the rod piece 210 that is located the top wall of smoke machine main body 100 and extends upwards, the upper part of rod piece 210 movably provided with at least two blocking pieces 220, blocking piece 220 can along the radial extension of rod piece 210 and be in unfolded state or along the radial retraction of rod piece 210 and be in storage state, rod piece 210 and blocking piece 220 in storage state can pass through the preinstallation hole 310 of the bottom plate of hanging cabinet 300, blocking piece 220 in unfolded state can abut to the upper surface of the bottom plate of hanging cabinet 300, and elastic member 230 is arranged between blocking piece 220 and rod piece 210, drives blocking piece 220 to keep in unfolded state.

[0030] Referring to Figures 1 to 4When installing the cabinet bottom range hood, the installer lifts up the various hanger rod assemblies 200 on the range hood body 100 towards the corresponding pre-installation holes 310, the blocking pieces 220 can compress the elastic pieces 230 and switch to the storage state when the blocking pieces 220 contact the pre-installation holes 310, and the blocking pieces 220 can switch to the unfolded state under the action of the elastic pieces 230 after the blocking pieces 220 pass the pre-installation holes 310, and the blocking pieces 220 are hung on the hanging bottom plate, thereby realizing the pre-installation of the cabinet bottom range hood, and the subsequent installation steps of the cabinet bottom range hood can be completed by using other fastening structures, so that the installation method is low in difficulty, suitable for single-person installation operation, and beneficial to reducing labor costs.

[0031] It can be understood that the pre-installation hole 310 can pass the rod piece 210 and the blocking piece 220 in the storage state together, and the blocking piece 220 in the unfolded state cannot be separated from the pre-installation hole 310 downward, therefore, the design range of the hole diameter size of the pre-installation hole 310 is large, the axial direction of the rod piece 210 does not need to be accurately aligned with the center line of the pre-installation hole 310, and the pre-installation of the cabinet bottom range hood can be realized, that is, the precision requirement of the pre-installation is low, and the operation requirement of single-person installation is met.

[0032] Referring to Figure 3 , Figure 4 and Figure 5 In some embodiments of the utility model, the lower end of the rod piece 210 is connected to the top wall of the range hood body 100, one end of the blocking piece 220 is rotatably connected to the upper part of the rod piece 210 through the radial pivot 240 along the rod piece 210, and the other end of the blocking piece 220 rotates around the pivot 240 to be stored in the side wall of the rod piece 210 or unfolded relative to the rod piece 210. It can be understood that when the blocking piece 220 rotates downward around the pivot 240 to the side of the rod piece 210, the blocking pieces 220 approach each other to make the maximum radial size of the hanger rod assembly 200 smaller and smoothly pass through the pre-installation hole 310, and after the blocking piece 220 passes the pre-installation hole 310, the elastic piece 230 drives the blocking piece 220 to rotate upward around the pivot 240 and unfold relative to the rod piece 210, and the maximum radial size of the hanger rod assembly 200 is larger and prevents the blocking piece 220 from passing through the pre-installation hole 310 downward. Of course, in other embodiments, the blocking piece 220 can also slide outward along the radial direction of the rod piece 210.

[0033] Referring to Figure 3 and Figure 4In some embodiments of the utility model, the upper portion of the rod piece 210 is provided with a through hole groove 211 along its radial direction, the extension direction of the pivot 240 is orthogonal to the through hole groove 211, the two resistance pieces 220 are provided, the pivot 240 is simultaneously provided in the two resistance pieces 220, the elastic piece 230 is a torsion spring provided in the pivot 240, the main body of the torsion spring is located in the through hole groove 211, and the two ends of the torsion spring are respectively abutted on the lower side of the two resistance pieces 220 to drive the resistance piece 220 to unfold upwards, and the upper end of the rod piece 210 is provided with a positioning piece 212 for limiting the angle position of the resistance piece 220 unfolded relative to the rod piece 210. Through the above structure, it is beneficial to improve the compactness of the boom assembly 200 and simplify the structure of the boom assembly 200, also help to reduce the maximum diameter size of the boom assembly 200 when the resistance piece 220 is in the storage state, so that the rod piece 210 and the resistance piece 220 in the storage state can smoothly pass through the pre-installation hole 310. It can be imagined that the two ends of the torsion spring drive the two resistance pieces 220 to switch to the unfolded state and abut on the bottom plate of the wall cupboard 300 located at the outer peripheral edge of the pre-installation hole 310.

[0034] Referring to Figure 4 and Figure 5 In some embodiments of the utility model, the two resistance pieces 220 are respectively a first metal plate and a second metal plate, the cross section of the first metal plate and the second metal plate is U-shaped, the pivot 240 is provided on the two sides of the first metal plate and the two sides of the second metal plate, and when the two resistance pieces 220 are in the storage state, the two side plates of the second metal plate are wrapped on the outer wall of the two side plates of the first metal plate. It can be understood that the width size of the U-shaped opening of the first metal plate and the U-shaped opening of the second metal plate is greater than the diameter size of the rod piece 210, so that the first metal plate and the second metal plate can be wrapped outside the rod piece 210 when in the storage state, reduce the maximum radial size of the boom assembly 200, and facilitate the rod piece 210 and the resistance piece 220 in the storage state to smoothly pass through the pre-installation hole 310.

[0035] Referring to Figure 3 and Figure 5In some embodiments of the utility model, the first metal plate and the second metal plate are both arranged obliquely outward from top to bottom and away from the rod 210, so that the first metal plate and the second metal plate can rotate towards each other when passing through the pre-installation hole 310 upwards to abut against the outer peripheral wall of the rod 210. It can be understood that under the action of the torsion spring, the first metal plate and the second metal plate rotate upwards around the pivot 240 to the unfolded state, at this time, the included angle between the first metal plate and the rod 210 and the included angle between the second metal plate and the rod 210 are both acute angles, when the upper end of the rod 210 passes through the pre-installation hole 310 upwards, the first metal plate and the second metal plate abut against the profiled edge of the lower end of the pre-installation hole 310, with the rod 210 moving upwards, the first metal plate and the second metal plate compress the torsion spring and rotate downwards to abut against the outer wall of the rod 210, so that the first metal plate and the second metal plate are automatically switched to the storage state without manual adjustment.

[0036] Referring to Figure 3 and Figure 4 In some embodiments of the utility model, the positioning member 212 is a cap body formed on the upper end of the rod 210, the radial dimension of the cap body is greater than the diameter dimension of the rod 210, and the one end of the anti-removal member 220 close to the pivot 240 is provided with a stop surface 221 capable of abutting against the lower end surface of the cap body. It can be understood that the lower end surface of the cap body and the stop surface 221 cooperate to limit the angle of expansion of the anti-removal member 220 relative to the rod 210, and when the gravity of the smoke machine body 100 drives the anti-removal member 220 to abut against the upper surface of the bottom plate of the wall cupboard 300, the angle position of the anti-removal member 220 can be stabilized, and the hanging assembly can stably hang the smoke machine body 100.

[0037] In some embodiments of the utility model, the rod 210 can move relative to the smoke machine body 100 to make the top wall of the smoke machine body 100 abut against the bottom wall of the wall cupboard 300. It can be understood that when there is a height space between the smoke machine body 100 and the bottom wall of the hanging, the smoke machine body 100 will shake, which is not conducive to the stable installation of the cabinet bottom range hood, and the problem can be solved after the rod 210 moves relative to the smoke machine body 100.

[0038] In some embodiments of the utility model, the lower part of the rod 210 is provided with a threaded column part, and the smoke machine body 100 is provided with a threaded hole or a nut member corresponding to the threaded column part. In this embodiment, the cap body is provided with a slot, and when the door plate of the hanging is opened, a screwdriver can be inserted into the slot to rotate the rod 210, and the smoke machine body 100 can move upwards relative to the wall cupboard 300 until the upper end surface of the smoke machine body 100 abuts against the bottom wall of the wall cupboard 300, so that the smoke machine body 100 does not shake or move.

[0039] Referring to Figure 2 In some embodiments of the present application, the top wall of the smoke machine body 100 is provided with a plurality of mounting holes 110, and the smoke machine body 100 is connected to the bottom wall of the hanging cabinet through fastening bolts passing through the mounting holes 110. It can be understood that after the pre-installation of the smoke machine body 100 is completed by using the hanger assembly 200, the fastening bolts can be used to pass through the mounting holes 110 and be screwed to the bottom plate of the hanging cabinet 300. Specifically, the smoke inlet of the smoke machine body 100 is generally designed in a detachable manner, and by detaching the parts near the smoke inlet, the smoke machine body 100 can be fixed to the hanging cabinet 300 by using the fastening bolts.

[0040] In some embodiments of the present application, the diameter of the rod 210 is smaller than the hole diameter of the pre-installation hole 310, which not only reduces the assembly difficulty, but also reserves a certain space for fine adjustment of the position of the smoke machine body 100 in the front, back, left and right directions on the hanging cabinet 300.

[0041] The technical features of the above embodiments can be combined arbitrarily, and in order to make the description concise, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.

[0042] Although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the present application, and the scope of the present application is defined by the claims and their equivalents.
