Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and particularly to an inner packaging structure and a packing box assembly. Background Art

[0002] When electrical appliances such as cold fans are being packaged and transported, the storage of power cords needs to be handled. The traditional packing method is to directly clip the power cord into a foam slot. However, since most power cords are made of PVC material, the above packing method will cause the power cord to be hard-pressed against the foam for a long time. Since the PVC power cord contains catalyst substances such as plasticizers, under certain conditions, the plasticizer will precipitate, resulting in the surface of the wire skin becoming sticky. Under strong extrusion, the foam film-like surface will be lifted, concretely manifested as foam sticking, leaving a layer of white crystalline film on the power cord, affecting the appearance of the power cord and resulting in a poor user experience. The existing solution is to reserve a certain length at the end where the power cord is connected to the body, then fold the remaining part of the power cord, put a power cord plastic bag on the folded part of the power cord, and then place the power cord with the plastic bag in the foam slot or directly in the gap of the packing box for packing to achieve the isolation between the power cord and the foam. However, in the general environment where products pursue high production efficiency, the packing method of putting plastic bags on the power cord has low packing efficiency and increases the production cost of the product. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention lies in the defects of low packing efficiency of electrical appliances and increased product cost in the prior art, so as to provide an inner packaging structure and a packing box assembly that can improve the packing efficiency of electrical appliances and save product cost.

[0004] To solve the above problems, the present invention provides an inner packaging structure for packaging electrical appliances. The electrical appliance includes a body and a power cord body. The inner packaging structure includes:

[0005] A first packaging member for supporting the first end in the length direction of the body;

[0006] A second packaging member for supporting the second end in the length direction of the body;

[0007] Wherein, a wire passing slot for placing the power cord body is provided on the first packaging member or the second packaging member, and the width of the wire passing slot is greater than the diameter of the power cord body.

[0008] As a preferred technical solution of the inner packaging structure, the wire passing slot includes an inlet and an outlet, and inclined slots are provided at both the inlet and the outlet.

[0009] As a preferred technical solution of the inner packaging structure, the slope of the slope groove at the wire inlet is different from the slope of the slope groove at the wire outlet.

[0010] As a preferred technical solution of the inner packaging structure, the wire groove further includes a flat groove, the flat groove is communicated with the slope groove, and the included angle between the slope groove and the flat groove is 105°-150°.

[0011] As a preferred technical solution of the inner packaging structure, a first placement groove is arranged above the flat groove, and the depth of the flat groove is greater than the sum of the depth of the first placement groove and the diameter of the power cord body.

[0012] As a preferred technical solution of the inner packaging structure, the inner packaging structure further includes a third packaging member, the third packaging member is arranged between the first packaging member and the second packaging member, and a power cord plug card slot is arranged on the third packaging member.

[0013] As a preferred technical solution of the inner packaging structure, a chassis groove is integrally formed on the top surfaces of the first packaging member, the second packaging member and the third packaging member, and the depth of the chassis groove is greater than or equal to the thickness of the chassis of the electrical equipment.

[0014] As a preferred technical solution of the inner packaging structure, the distance between the front groove wall of the chassis groove and the front side walls of the first packaging member and the second packaging member is a, and a>0.

[0015] As a preferred technical solution of the inner packaging structure, the distance between the chassis groove and the top walls of the assembly inner cavities of the first packaging member and the second packaging member is b, and b>0.

[0016] As a preferred technical solution of the inner packaging structure, the height h1 of the assembly inner cavity of the first packaging member and the height h2 of the assembly inner cavity of the second packaging member are both smaller than the height h3 of the assembly inner cavity of the third packaging member.

[0017] A packing box assembly includes a packing box and the above-mentioned inner packaging structure, the inner packaging structure is placed in the packing box, and there is an assembly gap between the inner packaging structure and the inner wall of the packing box.

[0018] As a preferred technical solution of the packing box assembly, the front wall of the assembly inner cavity of the first packaging member of the inner packaging structure is flush with the front wall of the assembly inner cavity of the second packaging member, and has a first gap with the inner wall of the packing box, and the distance L1 of the first gap is smaller than the width of the power cord plug of the electrical equipment; and / or,

[0019] The rear wall of the assembly inner cavity of the first packaging member is flush with the rear wall of the assembly inner cavity of the second packaging member, and there is a second gap between it and the inner wall of the packaging box, and the distance L2 of the second gap is less than the width of the power cord plug.

[0020] The technical solution of the present invention has the following advantages:

[0021] 1. The inner packaging structure provided by the present invention can be used for packaging electrical equipment, and the electrical equipment includes a body and a power cord body. The inner packaging structure includes: a first packaging member and a second packaging member. The first packaging member is used to support the first end in the length direction of the body; the second packaging member is used to support the second end in the length direction of the body; wherein, a wire groove position for placing the power cord body is provided on the first packaging member or the second packaging member, and the width of the wire groove position is greater than the diameter of the power cord body. By providing a wire groove position on the first packaging member or the second packaging member with a width greater than the diameter of the power cord body, when the power cord body passes through the wire groove position, the power cord body is in a loose state with the first packaging member or the second packaging member, ensuring that the contact time between the power cord and the first packaging member or the second packaging member under its own weight is relatively short, and it can avoid hard pressing between the power cord and the first packaging member or the second packaging member. Without wrapping the power cord with tape, it can also effectively avoid chemical reactions between the power cord and the foam, which can not only keep the power cord beautiful, but also improve the packing efficiency of electrical equipment and reduce production costs.

[0022] 2. The inner packaging structure provided by the present invention, the wire groove position includes an inlet and an outlet, and the inclined groove positions are provided at both the inlet and the outlet. By providing the inclined groove positions, when the power cord comes out from the bottom and then winds around the inlet of the wire groove position or passes through the outlet through the first packaging member or the second packaging member, the power cord does not closely adhere to the edge of the first packaging member or the second packaging member. While ensuring that the power cord does not break away from the wire groove position, it can ensure that the power cord will not come into long-term contact with the first packaging member or the second packaging member and cause chemical reactions. The structure is simple, and it can also improve the beauty of the power cord and the user experience.

[0023] 3. The inner packaging structure provided by the present invention, a first placement groove is provided above the flat groove position for placing other accessories (such as an ice crystal box) of the electrical equipment, and the depth of the flat groove position is greater than the sum of the depth of the first placement groove and the diameter of the power cord body. By providing the first placement groove, other accessories (such as an ice crystal box) can cover part of the wire groove position, making it difficult for the power cord to run to the upper part of the foam, ensuring that the power cord will not break out of the wire groove position and will not be hard pressed against the foam.

[0024] 4. The inner packaging structure provided by the present invention further includes a third packaging member disposed between the first packaging member and the second packaging member. A plug slot for placing a power cord plug is provided on the third packaging member. By providing the plug slot, the power cord plug is fixed, solving the problem that it is difficult to pack the power cord plug in the case of a small-sized package. The plug slot is suitable for a compatible power cord plug, improving the packing efficiency compared with the method of directly pasting the sealing tape on the fuselage and avoiding the problem of residual glue of the packaging tape.

[0025] 5. In the inner packaging structure provided by the present invention, a chassis slot is formed integrally on the top surfaces of the first packaging member, the second packaging member, and the third packaging member, and the depth of the chassis slot is greater than or equal to the thickness of the chassis to be assembled. After placing the chassis to be assembled, the top surface of the chassis to be assembled is flush with or lower than the edges of the first packaging member, the second packaging member, and the third packaging member, ensuring a buffer distance on the top surface of the chassis to be assembled and effectively preventing the phenomenon that the chassis to be assembled moves due to external vibration, improving the packaging effect.

[0026] 6. In the inner packaging structure provided by the present invention, the distance between the front slot wall of the chassis slot and the front side walls of the first packaging member and the second packaging member is a, where a > 0. After placing the chassis to be assembled, the chassis to be assembled is limited in the front-back and left-right directions, and there is a buffer distance in the front-back direction of the chassis to be assembled, avoiding damage caused by collision.

[0027] 7. In the inner packaging structure provided by the present invention, the distance between the chassis slot and the top walls of the assembly cavities of the first packaging member and the second packaging member is b, where b > 0. After placing the chassis to be assembled, a certain distance needs to be maintained between the chassis and the fuselage, which can avoid the chassis hitting the fuselage.

[0028] 8. In the inner packaging structure provided by the present invention, the height h1 of the assembly cavity of the first packaging member and the height h2 of the assembly cavity of the second packaging member are both smaller than the height h3 of the assembly cavity of the third packaging member. During packaging, the weight of the fuselage is borne by the first packaging member and the second packaging member. There is a gap between the assembly cavity of the third packaging member and the fuselage, and there is also a certain gap between the bottom of the third packaging member and the bottom of the packaging box, enabling the third packaging member to move left and right for position adjustment, facilitating the assembly of the chassis. And after the chassis is placed in the chassis slot, the whole of the third packaging member is limited to prevent the third packaging member and the chassis from moving, improving the packaging effect.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0048] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Such as Figure 1 、 2As shown, it is a preferred embodiment of the inner packaging structure of the present invention. This inner packaging structure can be used for packing electrical appliances, can keep the power cord body beautiful, improve the packing efficiency of electrical appliances, and reduce the production cost at the same time.

[0050] The above-mentioned electrical appliances include but are not limited to the following types: tower cool fans, air conditioners, dehumidifiers. This embodiment takes the tower cool fan as an example. The tower cool fan includes a body 1, a power cord body 2, a power cord plug 14, a chassis 10, an ice crystal box 15, a remote control 16, etc. Of course, the tower cool fan should also have other structures and components that existing tower cool fans have. Since these structures and components are not involved in this embodiment, they will not be elaborated here.

[0051] The inner packaging structure of this embodiment includes: a first packaging member 3 and a second packaging member 4. The first packaging member 3 is used to support the first end in the length direction of the body 1, and the second packaging member 4 is used to support the second end in the length direction of the body 1, that is, the weight of the body 1 is jointly supported by the first packaging member 3 and the second packaging member 4. Among them, a wire groove position for placing the power cord body 2 is provided on the first packaging member 3 or the second packaging member 4, and the width of the wire groove position is greater than the diameter of the power cord body 2.

[0052] By setting a wire groove position on the first packaging member 3 or the second packaging member 4 with a width greater than the diameter of the power cord body 2, when the power cord body 2 passes through the wire groove position, a loose state is maintained between the power cord body 2 and the inner wall of the wire groove position without being tightly clamped, ensuring that the power cord contacts the first packaging member 3 or the second packaging member 4 under its own weight but will not be hard pressed, thereby keeping the power cord beautiful, eliminating the need to sleeve a plastic bag, improving the packing efficiency of electrical appliances, and reducing the production cost.

[0053] Specifically, as Figure 2 、 4As shown in FIGS. 3 and 5, the first packaging member 3 is made of foam material. The first packaging member 3 includes an upper left foam 301 and a lower left foam 302 both provided with first recesses, and a first installation position (assembly inner cavity) is formed through the first recesses. First insertion blocks 303 are respectively provided on opposite sides of the lower left foam 302, and a first slot 304 that cooperates with the first insertion blocks 303 is provided on the upper left foam 301. By providing the first insertion blocks 303 and the first slots 304, it plays a guiding and positioning role in the assembly of the upper left foam 301 and the lower left foam 302, improving the assembly efficiency. The wire passing groove position is provided on the upper left foam 301. The foam member has good resistance and certain flexibility, and can play a buffering and shock-absorbing effect on external impacts during packaging and transportation, playing a good protective role for electrical equipment. In addition, the foam member has a low mass, will not bring additional extra weight during the packaging and transportation of electrical equipment, and the foam member can be processed and formed at one time, and the wire passing groove position is formed at one time during the processing, with high production and processing efficiency and low production cost. When packaging electrical equipment, place the top of the fuselage 1 in the first recess of the lower left foam 302, and then assemble the upper left foam 301 to the lower left foam 302 through the first slot 304 and the first insertion blocks 303, so that the fuselage 1 is completely placed in the first installation position, which can protect the top of the fuselage 1 and avoid top bumps, further improving the protective effect of the first packaging member 3 on the fuselage 1.

[0054] The second packaging member 4 is made of foam material. The second packaging member 4 includes an upper right foam 401 and a lower right foam 402 both provided with second recesses, and a second installation position (assembly inner cavity) is formed through the second recesses. Second insertion blocks 403 are respectively provided on opposite sides of the lower right foam 402, and a second slot 404 that cooperates with the second insertion blocks 403 is provided on the upper right foam 401. By providing the second insertion blocks 403 and the second slots 404, it plays a guiding and positioning role in the assembly of the upper right foam 401 and the lower right foam 402, improving the assembly efficiency. A remote control card slot 122 for placing the remote control 16 is also provided on the upper right foam 401. The foam member has good resistance and certain flexibility, and can play a buffering and shock-absorbing effect on external impacts during packaging and transportation, playing a good protective role for electrical equipment. In addition, the foam member has a low mass, will not bring additional extra weight during the packaging and transportation of electrical equipment, and the foam member can be processed and formed at one time, with high production and processing efficiency and low production cost. When packaging electrical equipment, place the bottom of the fuselage 1 in the second recess of the lower right foam 402, and then assemble the upper right foam 401 to the lower right foam 402 through the second slot 404 and the second insertion blocks 403, so that the fuselage 1 is completely placed in the second installation position, which can protect the bottom of the fuselage 1 and avoid bottom bumps, further improving the protective effect of the second packaging member 4 on the fuselage 1.

[0055] In a preferred embodiment, the wire passing slot includes a wire inlet and a wire outlet, and the wire inlet and the wire outlet are both provided with the slope slot 501. Specifically, the wire inlet and the wire outlet of the wire passing slot are both provided with the slope slot 501, and the power cord body 2 is stored by the wire passing slot body, and the wire passing slot body also has a certain guiding effect on the power cord body 2, which can effectively avoid the risk of damage caused by the power cord body 2 being entangled together. At the same time, the slope slot 501 is tilted downward, and the power cord body 2 passes through the upper left foam 301 after coming out from the bottom, and is wound around the wire inlet of the wire passing slot, and is wound out from the wire outlet. The power cord body 2 is not tightly attached to the edge of the upper left foam 301, and is not hard pressed. While ensuring that the power cord body 2 does not leave the wire passing slot, it is ensured that the power cord body 2 will not be in contact with the upper left foam 301 for a long time and chemical reaction will occur, thereby improving the beauty and user experience of the power cord body 2. In a preferred embodiment, the slope of the slope slot at the wire inlet is different from the slope of the slope slot at the wire outlet. Specifically, Figure 4 , 5 As shown in Figure 6, in this embodiment, the inclined slot includes a first inclined slot 5011 set at the line entrance of the line passing slot and a second inclined slot 5012 set at the line exit of the line passing slot. The first inclined slot 5011 and the second inclined slot 5012 are both set on the upper left foam 301. Since the edge portion opened on the upper left foam 301 is a right angle, the line entrance is made into an inclined slot 501, so that the power cord body 2 passes through the foam after coming out from the bottom and goes around to the upper left foam 301. The power cord body 2 is straightened and will not be tightly attached to the foam, thereby avoiding the power cord body 2 from sticking to the foam part. The first inclined slot 5011 is set at the line entrance, so that the power cord body 2 can avoid being tightly attached to the edge of the upper left foam 301 when it is in a taut state. The second inclined groove 5012 provided at the outlet can avoid a certain margin when the power cord body 2 is discharged, and avoid the power cord body from being pressed against the upper left foam 301 due to the change in angle when the power cord body is discharged. The inclination of the inclined groove 501 at the inlet is different from the inclination of the inclined groove 501 at the outlet, and can be adjusted according to the length of the power cord body 2, the size of the foam piece, etc., to maximize the above effect. At the same time, the groove width of the first inclined groove 5011 gradually decreases along the length direction, and the groove width of the second inclined groove 5012 gradually increases along the length direction, ensuring that when the power cord enters and exits, the power cord will not irregularly squeeze the upper left foam 301 due to bending and rebounding.

[0056] In other embodiments, the slope of the slope slot at the line inlet may be the same as the slope of the slope slot at the line outlet.

[0057] In a preferred embodiment, the wire trough position further includes a flat trough position 502 which is communicated with the inclined trough position 501, and the flat trough position 502 is disposed between the wire inlet and the wire outlet. The included angle between the inclined trough position 501 and the flat trough position 502 is 105°-150°, that is, the included angle between the bottom of the inclined trough position 501 and the bottom of the flat trough position 502. In this embodiment, the included angle between the first inclined trough 5011 and the flat trough position 502 is 105°, and the included angle between the second inclined trough 5012 and the flat trough position 502 is 150°.

[0058] In other embodiments, the included angle between the inclined trough position 501 and the flat trough position 502 is 110°, 120°, etc.

[0059] In a preferred embodiment, a first placement groove 701 is provided above the flat trough position 502, and the depth of the flat trough position 502 is greater than the sum of the depth of the first placement groove 701 and the diameter of the power cord body 2. Specifically, as shown in FIGS. Figure 1 , 7 and 11, the first placement groove 701 is formed on the upper surface of the upper left foam 301 for placing the ice crystal box 15. Since there are two ice crystal boxes 15 for the tower type cold fan, a second placement groove is also formed on the upper surface of the upper right foam 401 for placing the ice crystal box 15.

[0060] Since the first placement groove 701 is provided above the flat trough position 502, after the ice crystal box 15 is placed, the ice crystal box 15 can cover part of the power cord body 2 in the flat trough position 502, making it difficult for the power cord body 2 to come out of the wire trough position, better fixing the power cord body 2, and at the same time not generating hard pressure with the upper left foam 301 or the upper right foam 401.

[0061] In a preferred embodiment, the inner packaging structure further includes a third packaging member 8 which is disposed between the first packaging member 3 and the second packaging member 4, and the third packaging member 8 is made of foam material. Specifically, as shown in FIGS. Figure 2 , 9As shown in FIGS. 9 and 10, the third packaging member 8 includes an upper-middle foam 801 and a lower-middle foam 802 both provided with third recesses, and a third mounting position is formed by the third recesses. Third insertion blocks 803 are respectively provided on opposite sides of the lower-middle foam 802, and the upper-middle foam 801 is provided with third slots 804 that cooperate with the third insertion blocks 803. By providing the third insertion blocks 803 and the third slots 804, it plays a guiding and positioning role in the assembly of the upper-middle foam 801 and the lower-middle foam 802, improving the assembly efficiency. The foam member has good resistance performance and certain flexibility, and can play a buffering and shock-absorbing effect on external impacts during packaging and transportation, playing a good protective role for electrical equipment. In addition, the foam member has a low mass, will not bring additional extra weight during the process of packaging and transporting electrical equipment, and the foam member can be formed in one processing, with high production and processing efficiency and low production cost. When packaging electrical equipment, the bottom of the fuselage 1 is placed in the third recess of the lower-middle foam 802, and then the upper-middle foam 801 is assembled to the lower-middle foam 802 through the third slots 804 and the third insertion blocks 803, so that the fuselage 1 is completely placed in the third mounting position, further enhancing the protective effect of the third packaging member 8 on the fuselage 1.

[0062] In a preferred embodiment, a plug card slot 601 for placing the power cord plug 14 is provided on the third packaging member 8. Specifically, as Figure 1 、 2 shown in FIGS. 8 and 9, a receiving groove 602 for connecting the power cord body 2 of the power cord plug 14 is further formed on the upper-middle foam 801 provided with the plug card slot 601. After the power cord body 2 comes out from the bottom of the fuselage 1, it winds around the wire passing groove position through the edge of the upper-left foam 301, so that a part of the power cord body 2 is placed in the wire passing groove position, and then the power cord plug 14 is placed in the plug card slot 601. By providing the receiving groove 602, the part of the power cord body 2 close to the power cord plug 14 is fixed, so that the power cord plug 14 is better fixed in the plug card slot 601, improving the limit fixing effect.

[0063] In a preferred embodiment, a chassis slot 901 is integrally formed on the top surfaces of the first packaging member 3, the second packaging member 4, and the third packaging member 8. Specifically, as Figure 1 、 7As shown in Figures 9 and 11, the number of the chassis 10 is two, and the shape is semi-circular. A part of the chassis slot 901 is formed on the top surface of one end of the upper left foam 301 close to the middle upper foam 801, the top surfaces of both ends of the middle upper foam 801, and the top surface of one end of the upper right foam 401 close to the middle upper foam 801, so as to jointly form two chassis slots 901. When packing, one chassis 10 is placed in the chassis slot 901 formed between the upper left foam 301 and the middle upper foam 801, and the other chassis 10 is placed in the chassis slot 901 formed between the middle upper foam 801 and the upper right foam 401, and the edges of the two chassis 10 are respectively adapted to the chassis slot 901.

[0064] In a preferred embodiment, the depth of the chassis slot 901 is greater than or equal to the thickness of the chassis 10 to be assembled. After placing the chassis 10 to be assembled, the top surface of the chassis 10 to be assembled is flush with or lower than the top surface edges of the upper left foam 301, the middle upper foam 801, and the upper right foam 401, ensuring a buffer distance on the top surface of the chassis 10, effectively preventing the phenomenon that the chassis 10 moves due to external vibration and improving the packaging effect.

[0065] In a preferred embodiment, the distance between the front slot wall of the chassis slot 901 and the front side walls of the first package 3 and the second package 4 is a, and a > 0. Specifically, as Figure 1 shown, since the chassis 10 is embedded in the chassis slot 901, the chassis 10 is limited in the front-back and left-right directions. The distances between the front side walls of the two chassis slots 901 and the front side walls of the upper left foam 301, the middle upper foam 801, and the upper right foam 401 are all greater than 0. At the same time, the distance c between the rear slot wall of the chassis slot 901 and the rear side walls of the upper left foam 301, the middle upper foam 801, and the upper right foam 401 is also greater than 0. That is to say, after placing the chassis 10, there is a certain assembly gap between the front and rear side walls of the chassis 10 and the edges of the upper left foam 301, the middle upper foam 801, and the upper right foam 401, and there is a buffer distance in the front and back of the chassis 10, avoiding the collision between the chassis 10 and the packaging box when placed in the packaging box and causing damage, and improving the stability of the chassis 10 assembly.

[0066] In a preferred embodiment, the distance between the chassis slot 901 and the top walls of the assembly inner cavities of the first package 3 and the second package 4 is b, and b > 0. Specifically, as Figure 2 shown, during assembly, after the chassis 10 is placed in the chassis slot 901, a certain distance needs to be maintained between the bottom of the chassis 10 and the fuselage 1, which can avoid the chassis 10 hitting the fuselage 1.

[0067] In a preferred embodiment, the assembly inner cavity height h1 of the first package 3 and the assembly inner cavity height h2 of the second package 4 are both less than the assembly inner cavity height h3 of the third package 8. Specifically, asFigure 3 As shown, after the upper left foam 301 is assembled with the lower left foam 302, the upper right foam 401 is assembled with the lower right foam 402, and the middle upper foam 801 is assembled with the middle lower foam 802, an assembly inner cavity is formed in the first packaging member 3, and an assembly inner cavity is formed in the second packaging member 4. The height of the assembly inner cavities of the two side foam members (the first packaging member 3 and the second packaging member 4) is less than the height of the assembly inner cavity of the middle foam member. This is because when packaging, the weight of the fuselage 1 is borne by the lower left foam 302 and the lower right foam 402. There is a gap between the assembly inner cavities of the middle upper foam 801 and the middle lower foam 802 and the fuselage 1, and there is a certain assembly gap between the bottom of the middle lower foam 802 and the bottom of the packaging box, so that the middle upper foam 801 and the middle lower foam 802 can move left and right for position adjustment, facilitating the assembly of the chassis 10 into the two chassis 10 slots respectively. And after the chassis 10 is placed in the chassis slot 901, the middle upper foam 801 is limited, so that the middle upper foam 801 cannot move, and then the middle lower foam 802 inserted with the middle upper foam 801 is limited, avoiding the movement of the whole third packaging member 8 and the chassis 10, and improving the packaging effect.

[0068] This embodiment also provides a packaging box assembly, including a packaging box and an inner packaging structure. The inner packaging structure is placed inside the packaging box, and there is an assembly gap between the inner packaging structure and the inner wall of the packaging box.

[0069] The above-mentioned packaging box can be selected from the common 0201 box type or other box types, and can be a swing lid packaging box. The box body, the box lid and the box bottom are integrally formed. The box lid is swung down to cover the box mouth, and there are swing lids 13 on both sides. This kind of packaging box has a simple structure and high packaging efficiency.

[0070] The packaging box assembly proposed in this embodiment includes the inner packaging structure of the above technical solution. Therefore, it has all the beneficial effects of the above inner packaging structure and will not be elaborated here in detail.

[0071] Furthermore, the front wall of the assembly inner cavity of the first packaging member 3 of the inner packaging structure is flush with the front wall of the assembly inner cavity of the second packaging member 4, and has a first gap with the inner wall of the packaging box. The distance L1 of the first gap is less than the width of the power cord plug 14 of the electrical equipment; and / or, the rear wall of the assembly inner cavity of the first packaging member 3 is flush with the rear wall of the assembly inner cavity of the second packaging member 4, and has a second gap with the inner wall of the packaging box. The distance L2 of the second gap is less than the width of the power cord plug 14. Through the above design, when the packaging box assembly of this embodiment packages the electrical equipment, the power cord plug 14 of the electrical equipment has two packaging forms.

[0072] The packaging box assembly of this embodiment has two packaging methods:

[0073] Wind the power cord 2 of the electrical equipment around the inlet of the wire groove position of the first packaging member 3 or the second packaging member 4 and into the flat groove position 502, and then wind it out from the outlet;

[0074] Place the power cord plug 14 of the electrical equipment in the plug card slot 601 on the third packaging member 8; alternatively, insert the power cord plug 14 into the first gap between the front wall of the assembly inner cavity of the first packaging member 3, the front wall of the assembly inner cavity of the second packaging member 4 and the inner wall of the packaging box, and then place it at the bottom of the packaging box; or insert the power cord plug 14 into the second gap between the rear wall of the assembly inner cavity of the first packaging member 3, the rear wall of the assembly inner cavity of the second packaging member 4 and the inner wall of the packaging box, and then place it at the bottom of the packaging box, effectively limiting and fixing the power cord plug 14 while improving the packing efficiency.

[0075] By adopting the above two packaging methods for the power cord plug 14, the packing of the power cord plug 14 can be divided into two forms according to the different widths of the power cord plug 14 and the sizes of the assembly gaps, improving the packing efficiency and effect.

[0076] In this embodiment, wind the power cord 2 of the electrical equipment around the inlet of the wire groove position of the first packaging member 3 or the second packaging member 4 and into the flat groove position 502, and then wind it out from the outlet; put the power cord plug 14 into a short plastic bag about 200 mm long, and then place it in the plug card slot 601 on the third packaging member 8. Fix the power cord plug 14 in the above-mentioned clamping manner, which is relatively easy to operate in actual production, and at the same time well solves the problem that the power cord plug 14 is difficult to pack, avoids the risk of the power cord plug 14 being randomly placed and damaging the whole machine during transportation, and at the same time avoids the risk of the power cord 2 being clamped and adhered to the foam film by the first packaging member 3 or the second packaging member 4.

[0077] Further, the packaging method of the tower fan by the packaging box assembly of this embodiment will be described in detail below:

[0078] First, put the left-lower foam 302, the middle-lower foam 802 and the right-lower foam 402 into the packaging box, then put the body 1 covered with the whole-machine plastic bag into the first recess of the left-lower foam 302, the second recess of the middle-lower foam 802 and the third recess of the right-lower foam 402, and then put the left-upper foam 301, the middle-upper foam 801 and the right-upper foam 401 respectively, and plug and fix them respectively; then wind the power cord 2 out from the wire groove position of the left-upper foam 301, put the power cord plug 14 into a plastic bag and place the power cord plug 14 in the plug card slot 601 of the middle-upper foam 801 for fixing; finally, adjust the positions of the middle-upper foam 801 and the middle-lower foam 802, place the two chassis 10 in the chassis slot 901, and assemble the ice crystal box 15 and the remote control 16 to complete the assembly and packing process.

[0079] In other embodiments, the slope slot 501 may be provided only at the inlet of the wire slot, or only at the outlet of the wire slot.

[0080] In other embodiments, it may only be necessary to ensure that the front wall of the assembly cavity of the first packaging member 3 of the inner packaging structure is flush with the front wall of the assembly cavity of the second packaging member 4, and there is a first gap between the front wall and the inner wall of the packaging box. The distance L1 of the first gap is less than the width of the power cord plug 14 of the electrical equipment. In this case, the power cord plug 14 can be placed on the front wall of the assembly cavity. Or it may only be necessary to ensure that the rear wall of the assembly cavity of the first packaging member 3 is flush with the rear wall of the assembly cavity of the second packaging member 4, and there is a second gap between the rear wall and the inner wall of the packaging box. The distance L2 of the second gap is less than the width of the power cord plug 14. In this case, the power cord plug 14 can be placed on the rear wall of the assembly cavity.

[0081] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
