DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] like Figures 2 to 12 As shown, the decorative cover structure provided by the present invention includes a box assembly 100, and a decorative cover 300 that is vertically slidably mounted on the outside of the box assembly 100. A box outer cover 200 can also be provided on the outside of the decorative cover 300. The box outer cover 200 is fixedly connected to the smoke collection hood. The decorative cover 300 is slidably mounted between the box assembly 100 and the box outer cover 200. The box outer cover 200 serves to shield the box assembly 100, and the decorative cover 300 serves to shield the air outlet hood and the air duct on the top of the range hood.

[0045] A locking structure 400 is provided between the box assembly 100 and the decorative cover 300. When the locking structure 400 is locked, the box assembly 100 and the decorative cover 300 are relatively fixed. The locking structure 400 includes a first connector provided on the inner side wall of the decorative cover 300, and a driving assembly and a second connector provided on the box assembly 100. The driving assembly is connected to the second connector to drive the second connector to connect to or disconnect from the first connector, so that the locking structure 400 is in a locked or unlocked state. When the locking structure 400 is in the locked state, the box assembly 100 and the decorative cover 300 are relatively fixed. When the locking structure 400 is in the unlocked state, the box assembly 100 and the decorative cover 300 can move relative to each other.

[0046] During use, when the second connector is driven to separate from the first connector by the driving assembly of the locking structure 400, the housing assembly 100 and the decorative cover 300 are unlocked, and the decorative cover 300 can slide vertically relative to the housing assembly 100 to meet different height requirements. When the second connector is connected to the first connector, the sliding lock between the housing assembly 100 and the decorative cover 300 is locked, thereby fixing the position of the decorative cover 300. In this solution, the locking structure 400 is used to lock or unlock the decorative cover 300 slidably connected to the housing assembly 100, thereby facilitating the adjustment and fixation of the upper and lower positions of the cover, reducing the time required to adjust the cover, and improving the efficiency of the range hood installation.

[0047] Furthermore, there are two locking structures 400 , and the two locking structures 400 are respectively arranged on both sides of the box assembly 100 . The locking structures 400 located on the left and right sides of the box assembly 100 are subjected to more uniform force and have higher stability.

[0048] Preferably, the first connecting member is disposed at a lateral middle portion of the decorative cover 300 .

[0049] In this embodiment, the transverse surfaces of the decorative cover 300 are both U-shaped, and in the operating orientation of the range hood, the two locking structures 400 are located at opposite sides and symmetrically arranged about the center of the housing assembly 100. Preferably, the first connector is fixed to the middle of the lateral portion of the decorative cover 300, and the second connector is installed in the middle of the lateral portion of the housing assembly 100, corresponding to the first connector. When the two are connected, the housing assembly 100 and the decorative cover 300 are locked and fixed.

[0050] Furthermore, the locking structure 400 includes a fixing seat 410, which is provided with a through hole 411 facing the first connecting member, and the length direction of the through hole 411 is perpendicular to the side of the decorative cover 300. The second connecting member is located in the through hole 411 and can slide along the through hole 411. The driving component is arranged at an end of the fixing seat 410 away from the first connecting member and is connected to an end of the second connecting member away from the first connecting member. The driving mechanism pushes and pulls the second connecting member to connect or separate the second connecting member from the first connecting member.

[0051] The driving assembly further includes an elastic reset member, which is disposed between the fixing seat 410 and the second connecting member. The elastic reset member is used to make the second connecting member tend to move toward the direction where the first connecting member is located.

[0052] Specifically, the elastic return member is a spring 440, which is sleeved on the second connecting member. The second connecting member is provided with a stop portion for fixing one end of the spring 440. The other end of the spring 440 is connected to the fixing seat 410 in the through hole 411. The through hole 411 is provided with an end cover 450 near the opening of the first connecting member. The end cover 450 has a hole that allows the top end of the first connecting member to pass through, but cannot allow the stop portion to pass through. The spring 440 and the second connecting member are compressed and installed in the through hole 411 through the end cover 450. The spring 440 pushes the stop portion and pushes the top end of the second connecting member out of the end cover 450, thereby realizing the connection between the second connecting member and the first connecting member.

[0053] In this embodiment, the first connecting member is a rack 422; the second connecting member is a pin 421, and the pin 421 is connected to the driving assembly. The pin 421 is used to engage with or disengage from the rack 422 under the drive of the driving assembly.

[0054] Preferably, the rack 422 includes a plurality of tooth structures spaced apart along the length direction of the rack 422 , each tooth structure includes a first tooth line 4221 and a second tooth line 4222 connected to each other, and the angle between the first tooth line 4221 and the extension direction of the rack 422 is 25°-45°;

[0055] The included angle between the second tooth line 4222 and the extending direction of the rack 422 is 80°-100°.

[0056] Specifically, the rack 422 is provided with a plurality of tooth structures along its length direction. Taking a single tooth structure as an example, it is formed by a first tooth line 4221 and a second tooth line 4222 connected to each other, wherein the angle a between the first tooth line 4221 and the rack 422 in the length direction is in the range of 25°-45°, and the angle b between the second tooth line 4222 and the rack 422 in the length direction is in the range of 80°~100°. Such a design is conducive to the pulling and pulling of the decorative cover 300 and the clamping with the second connecting piece.

[0057] Furthermore, the driving assembly includes a first transmission rod 431, a second transmission rod 432, a first rotating shaft 433 and a second rotating shaft 434; the first transmission rod 431 includes a first end 4311 and a second end 4312 opposite to each other, and the second transmission rod 432 includes a third end 4321 and a fourth end 4322 opposite to each other; the fourth end 4322 of the second transmission rod 432 is connected to the second connecting member, and the position between the third end 4321 and the fourth end 4322 of the second transmission rod 432 is connected to the fixed member through the second rotating shaft 434. The seat 410 is hinged, and the position between the first end 4311 and the second end 4312 of the first transmission rod 431 is hinged to the fixed seat 410 through the first rotating shaft 433; the second end 4312 of the first transmission rod 431 is located on the side of the third end 4321 of the second transmission rod 432 facing away from the fixed seat 410, and the second end 4312 of the first transmission rod 431 is used to push the third end 4321 to rotate toward the fixed seat 410, so that the fourth end 4322 rotates toward the direction away from the fixed seat 410.

[0058] like Figure 7 As shown, when the decorative cover 300 is pulled upward, the pin 421 abuts against the rack 422 due to the action of the spring 440 and is pressed by the tooth structure on the rack 422, thereby preventing the decorative cover 300 from sliding off. When it is necessary to retract the decorative cover 300, the first end 4311 of the first transmission rod 431 is pushed to the left, and the second end 4312 of the first transmission rod 431 pushes the third end 4321 of the second transmission rod 432 to the right, the second transmission rod 432 rotates, and the fourth end 4322 of the second transmission rod 432 moves to the left, driving the pin shaft 421 to move to the left, thereby separating the pin shaft 421 from the rack 422, thereby ensuring the retraction of the decorative cover 300; when the decorative cover 300 moves to the appropriate position, the first transmission rod 431 is released, and the pin shaft 421 is driven by the spring 440 to move toward the rack 422 and engage with the tooth structure on the rack 422, thereby locking the box assembly 100 and the decorative cover 300.

[0059] Preferably, an inwardly recessed escape portion 412 is provided on the surface of the fixing base 410 corresponding to the junction of the first transmission rod 431 and the second transmission rod 432. The second end 4312 of the first transmission rod 431 and the third end 4321 of the second transmission rod 432 are both bent inwardly toward the escape portion 412. The provision of the escape portion 412 allows the first transmission rod 431 and the second transmission rod 432 to have greater rotational space.

[0060] The housing assembly 100 is provided with a first notch 101 and a second notch 102. The first notch 101 is provided to allow for the second connector to connect to the first connector through the first notch 101. The second notch 102 is provided to allow for the first end 4311 of the first transmission rod 431 to be positioned outside the housing assembly 100. After the range hood is secured to the roof, a worker can reach into the rear of the housing assembly 100 and push the first transmission rod 431 to adjust the relative position between the housing assembly 100 and the decorative cover 300.

[0061] In this embodiment, the locking structure 400 includes a fixing seat 410, a pin 421, an end cover 450, a spring 440, a first transmission rod 431, a second transmission rod 432, a first rotating shaft 433 and a second rotating shaft 434, wherein the spring 440 is sleeved on the pin 421, and the pin 421 is provided with a stopper for abutting against one end of the spring 440, the spring 440 is installed in the through hole 411 on the fixing seat 410, and the through hole 411 can be provided with a sink for abutting against one end of the spring 440 away from the stopper on the pin 421, the end cover 450 is provided with a hole for the working end of the pin 421 to pass through, and the end cover 450 is provided with a hole for the working end of the pin 421 to pass through.
