Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a packaging structure for an air duct cover. Background Art

[0002] The range hood is usually provided with a duct cover for covering the smoke outlet and the telescopic smoke duct. The duct cover is generally a separately detachable component. Since the cross section of the duct cover is usually U-shaped, when packaging the duct cover, the manufacturer usually directly bends the two opposite sides of the duct cover inward so that the cross section of the duct cover presents a triangle, and then places it in the packaging box of the whole machine and transports it together with the whole machine. After transporting it to the user's home, the duct cover is unfolded so that its cross section presents a U-shape again. However, this method will cause the two opposite sides of the duct cover to be severely deformed inward, which is not conducive to subsequent installation steps. Placing the duct cover directly in the packaging box of the whole machine will increase the packaging volume of the whole machine, which is not convenient for transportation and handling of the packaging box. The duct cover may also move during handling and transportation, which may easily cause the duct cover and the whole machine to be deformed or scratched by impact, seriously affecting the appearance of the duct cover and the whole machine.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference Figures 1 to 6 In one embodiment of the utility model, a packaging structure for a duct cover is provided, comprising a packaging box 200, a protective structure and a limiting plate 230. The packaging box 200 has a receiving cavity 201. The protective device is located in the receiving cavity 201, and a slot for accommodating the upper corner edge and the lower corner edge of the duct cover 100 is provided on the surface of the protective device. The limiting plate 230 is located in the receiving cavity 201, and the limiting plate 230 can be embedded in the duct cover 100 and abut against the two opposite side walls of the duct cover 100.

[0034] By adopting the air duct cover packaging structure of the embodiment of the utility model, the air duct cover 100 can be placed in the accommodating cavity 201 of the packaging box 200 during packaging, and the card slots of the protective device can fix the upper corner edges and the lower corner edges of the air duct cover 100, thereby reducing the risk of the two opposite side walls of the air duct cover 100 bending inward. In addition, by providing a limit plate 230, the limit plate 230 can be embedded in the air duct cover 100 and abut against the two opposite side walls of the air duct cover 100, thereby further reducing the risk of the two opposite side walls of the air duct cover 100 bending and deforming inward. At the same time, since the air duct cover packaging structure of the embodiment of the utility model can independently package the air duct cover 100, it can also reduce the risk of deformation and damage of the air duct cover 100 due to collision with other parts during handling and transportation.

[0035] It is understandable that the cross section of the duct cover 100 is usually U-shaped, the corner of the duct cover 100 specifically refers to the U-shaped corner of the duct cover 100, and the corner edge of the duct cover 100 specifically refers to the two side edges of the corner.

[0036] It is understandable that the surface of the protective device is provided with a slot for accommodating the upper corner edge and the lower corner edge of the air duct cover 100, which is only for Figures 1 to 6 As an exemplary illustration, in order to avoid bending and deformation between the two opposite side walls of the air duct cover 100, the slot provided on the surface of the protective device may also be used only to accommodate the upper corner edge of the air duct cover 100 or the lower corner edge of the air duct cover 100, and the present invention does not make any specific limitation on this.

[0037] Reference Figures 1 to 6 In some embodiments, the protective device includes a lower protective device 210 and an upper protective device 220. The lower protective device 210 is located at the bottom of the accommodating cavity 201, and the upper surface of the lower protective device 210 is provided with a lower groove for accommodating the two corner edges of the lower end of the air duct cover 100; the upper protective device 220 is located at the top of the accommodating cavity 201, and the lower surface of the upper protective device 220 is provided with an upper groove for accommodating the two corner edges of the upper end of the air duct cover 100.

[0038] In the above structure, during packaging, the two corner edges of the lower end of the air duct cover 100 are fixed by the lower groove of the lower protective device 210, and the two corner edges of the upper end of the air duct cover 100 are fixed by the upper groove of the upper protective device 220, thereby further reducing the risk of the two opposite side walls of the air duct cover 100 bending inward. In addition, the upper protective device 220 can also prevent the upper edge of the air duct cover 100 from directly abutting against the upper side wall of the accommodating chamber 201, and the lower protective device 210 can prevent the lower edge of the air duct cover 100 from directly abutting against the upper side wall of the accommodating chamber 201, thereby preventing the air duct cover 100 from abutting against the upper and lower side walls of the accommodating chamber 201 and causing damage to the air duct cover 100 or the packaging box 200, and also reducing the risk of the operator being scratched by the upper edge or lower edge of the air duct cover 100 during packaging.

[0039] It can be understood that in order to better fix the air duct cover 100, in some embodiments, the side of the lower protective device 210 abuts against the side wall of the installation cavity, and the side of the upper protective device 220 also abuts against the side wall of the installation cavity, thereby preventing the upper protective device 220 and the lower protective device 210 from shaking horizontally during handling and transportation, thereby better fixing the air duct cover 100 and preventing the air duct cover 100 from shaking and shifting during handling and transportation.

[0040] Reference Figures 1 to 6 In some embodiments, the lower protective device 210 includes two lower protective members 211 arranged opposite to each other, and the lower slot includes a lower L-shaped groove 212 opened on the upper surface of each lower protective member 211, the projection of the lower L-shaped groove 212 in the up and down directions is "L"-shaped, and the two lower L-shaped grooves 212 are arranged opposite to each other.

[0041] By adopting the above structure, the lower protection device 210 is divided into two independent lower protection parts 211, and the upper surface of each lower protection part 211 is provided with a lower L-shaped groove 212, thereby being able to respectively fix the two corner edges of the lower end of the air duct cover 100. By dividing the lower protection device 210 into two independent lower protection parts 211, the two corner edges of the lower end of the air duct cover 100 can be respectively packaged and fixed, and the operation is more convenient and simple.

[0042] Reference Figures 1 to 6 In some embodiments, there is a gap between the two lower protective members 211, thereby saving materials of the protective device and further reducing the cost of the duct cover packaging structure.

[0043] It can be understood that in addition to being divided into two independent lower protective parts 211, the lower protective device 210 can also be directly set as an integrally formed structure, and a U-shaped groove compatible with the air duct cover 100 is opened on the upper surface of the lower protective device 210, and the projection of the U-shaped groove in the up and down directions is "U"-shaped, thereby fixing the entire lower edge of the air duct cover 100, further avoiding the lower end of the air duct cover 100 directly abutting against the inner wall of the accommodating cavity 201 and causing damage to the air duct cover 100 or the packaging box 200, and at the same time further reducing the risk of the operator being scratched by the lower edge of the air duct cover 100 during packaging.

[0044] Reference Figures 1 to 6 In some embodiments, the upper protective device 220 includes two upper protective members 221 arranged opposite to each other, and the upper slot includes an upper L-shaped groove 222 opened on the upper surface of each upper protective member 221, the projection of the upper L-shaped groove 222 in the up and down directions is "L" shaped, and the two upper L-shaped grooves 222 are arranged opposite to each other.

[0045] By adopting the above structure, the upper protection device 220 is divided into two independent upper protection pieces 221, and the lower surface of each upper protection piece 221 is provided with an upper L-shaped groove 222, thereby respectively fixing the two corner edges of the upper end of the air duct cover 100. Therefore, by dividing the upper protection device 220 into two independent upper protection pieces 221, the two corner edges of the upper end of the air duct cover 100 can be respectively packaged and fixed, and the operation is more convenient and simple.

[0046] Reference Figures 1 to 6 In some embodiments, there is a gap between the two upper protective members 221, thereby saving materials of the protective device and further reducing the cost of the duct cover packaging structure.

[0047] It can be understood that, in addition to being divided into two independent upper protective parts 221, the upper protective device 220 can also be directly set as an integrally formed structure, and a U-shaped groove compatible with the air duct cover 100 is opened on the upper surface of the upper protective device 220, and the projection of the U-shaped groove in the up and down directions is "U"-shaped, thereby fixing the entire upper edge of the air duct cover 100, further avoiding the upper end of the air duct cover 100 directly abutting against the inner wall of the accommodating cavity 201 and causing damage to the air duct cover 100 or the packaging box 200, and at the same time further reducing the risk of the operator being scratched by the upper edge of the air duct cover 100 during packaging.

[0048] It can be understood that in order to better fix the air duct cover 100, in some embodiments, the two lower protective parts 211 of the lower protective device 210 are respectively against the two opposite corners of the lower end of the accommodating chamber 201, and the two upper protective parts 221 of the upper protective device 220 are respectively against the two opposite corners of the upper end of the accommodating chamber 201, thereby preventing the upper protective device 220 and the lower protective device 210 from shaking horizontally during handling and transportation, thereby better fixing the air duct cover 100 and preventing the air duct cover 100 from shaking and shifting during handling and transportation.

[0049] In some embodiments, the guard is a foam member.

[0050] In the above structure, by setting the protective device as a foam component, the air duct cover 100 can be effectively fixed and protected. At the same time, when it collides with other structures during handling and transportation, the protective device can also play a buffering role, effectively reducing the risk of bending, deformation or damage of the air duct cover 100. In addition, the foam component is a universal material and is easy to obtain.

[0051] It is understandable that the protective device may be made of not only foam components but also flexible components, such as silicone components, rubber components, etc., and the present invention does not make any specific limitation on this.

[0052] Reference Figure 1 In some embodiments, the upper protection device 220 and the lower protection device 210 are both located on the same side of the limiting plate 230 and abut against the limiting plate 230 .

[0053] In the above structure, the upper protective device 220 and the lower protective device 210 are both arranged on the same side of the limiting plate 230 and abut against the limiting plate 230, thereby making the packaging structure of the air duct cover more compact and stable, and further preventing the air duct cover 100 from shaking or shifting during transportation.

[0054] It is understandable that, in addition to setting the upper protective device 220 and the lower protective device 210 on the same side of the limit plate 230 and abutting against the limit plate 230, in some embodiments, the limit plate 230 can also be directly set between the upper protective device 220 and the lower protective device 210, and the present invention does not make specific limitations on this.

[0055] Reference Figures 1 to 8 In some embodiments, the air duct cover 100 includes an upper cover body 110 and a lower cover body 120. The upper cover body 110 can be inserted into the lower cover body 120 and slide relative to the lower cover body 120. The limit plate 230 can be embedded in the upper cover body 110 and abut against the two opposite side walls of the upper cover body 110.

[0056] In order to match the difference of different installation heights, the air duct cover 100 is often made into two parts, namely, an upper cover body 110 and a lower cover body 120. The upper cover body 110 is inserted into the lower cover body 120 and can slide relative to the lower cover body 120, thereby adjusting the overall height of the air duct cover 100 according to different installation heights. At this time, in order to facilitate the packaging of the air duct cover 100, by adopting the air duct cover packaging structure of the embodiment of the utility model, the upper cover body 110 can be inserted into the lower cover body 120 during packaging, thereby reducing the overall volume of the air duct cover 100, and further reducing the volume of the air duct cover packaging structure. By embedding the limiting plate 230 into the upper cover body 110 and abutting against the two side walls opposite to the upper cover body 110, the risk of the two side walls opposite to the upper cover body 110 and the lower cover body 120 bending and deforming inward can be reduced.

[0057] Reference Figures 1 to 8 In some embodiments, the width of the lower card slot is greater than or equal to the sum of the thicknesses of the lower cover body 120 and the upper cover body 110. When the upper cover body 110 is inserted into the lower cover body 120, the two corner edges of the lower ends of the lower cover body 120 and the upper cover body 110 are both embedded in the lower card slot; the width of the upper card slot is greater than or equal to the sum of the thicknesses of the lower cover body 120 and the upper cover body 110. When the upper cover body 110 is inserted into the lower cover body 120, the two corner edges of the lower ends of the upper cover body 110 and the lower cover body 120 are both embedded in the upper card slot.

[0058] By adopting the above structure, the lower card groove can fix the lower ends of the upper cover body 110 and the lower cover body 120 at the same time, and the upper card groove can fix the upper ends of the upper cover body 110 and the lower cover body 120 at the same time, thereby making the air duct cover packaging structure more firm and stable, and can better fix the air duct cover 100 to avoid bending and deformation of the opposite side walls of the air duct cover 100.

[0059] It can be understood that in some embodiments, when the upper cover body 110 is inserted into the lower cover body 120, the lower end of the upper cover body 110 is flush with the lower end of the lower cover body 120, and the upper end of the upper cover body 110 is located inside the lower cover body 120. At this time, it is only necessary that the width of the lower card slot is greater than or equal to the sum of the thicknesses of the lower cover body 120 and the upper cover body 110.

[0060] It can be understood that in some embodiments, when the upper cover body 110 is inserted into the lower cover body 120, the upper end of the upper cover body 110 is flush with the upper end of the lower cover body 120, and the lower end of the upper cover body 110 is located inside the lower cover body 120. At this time, it is only necessary that the width of the upper card slot is greater than or equal to the sum of the thicknesses of the lower cover body 120 and the upper cover body 110.

[0061] In some embodiments, the duct cover packaging structure further includes an isolation member for isolating the upper cover body 110 and the lower cover body 120 , and the isolation member can be embedded between the upper cover body 110 and the lower cover body 120 .

[0062] By adopting the above structure, the isolation piece is embedded between the upper cover body 110 and the lower cover body 120 during packaging, thereby isolating the upper cover body 110 and the lower cover body 120, avoiding scratches and damages of the upper cover body 110 and the lower cover body 120 due to relative movement during handling and transportation, thereby protecting the upper cover body 110 and the lower cover body 120.

[0063] It can be understood that the above-mentioned isolation member can be a first packaging plastic bag for packaging the upper cover body 110, or a second packaging plastic bag for packaging the lower cover body 120, or the isolation member can include both the first plastic bag and the second plastic bag, which is not specifically limited in the present invention.

[0064] In some embodiments, the limiting plate 230 may be made of honeycomb paperboard.

[0065] In the above structure, honeycomb paperboard is a high-quality packaging material with the characteristics of light weight, low price, high strength and recyclability. By using honeycomb paperboard as the limit plate 230, the air duct cover 100 can be better protected and the risk of bending and deformation of the two opposite side walls of the air duct cover 100 can be reduced.

[0066] It is understandable that, in addition to honeycomb paperboard, the limiting plate 230 may also be made of corrugated paperboard or other limiting materials, and the present invention does not make any specific limitation on this.

[0067] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
