[0006] The box cover provided by the utility model has the following beneficial effects compared with the background technology:

[0007] In the above-mentioned box cover, a recessed portion is provided at the upper part of the side where the first cover body and the second cover body are connected to form a water receiving groove, and a drainage hole is provided on at least one side of the first cover body along the length direction of the water receiving groove, and the drainage hole is connected to the water receiving groove, thereby conveniently draining the accumulated water in the water receiving groove. By providing a sealing structure between the first cover body and the second cover body, the sealing structure and the water receiving groove are staggered along the width direction of the water receiving groove, thereby, the accumulated water in the water receiving groove can be preferentially discharged from the drainage hole, reducing the probability of accumulated water penetrating the sealing structure, and reducing the probability of water leakage at the connection position of the first cover body and the second cover body, thereby effectively improving the sealing performance at the connection position of the first cover body and the second cover body, and then improving the sealing performance of the box cover. When the box cover is applied to a storage box, the quality of the items in the storage box can be guaranteed, and the user experience can be improved.

[0008] In one embodiment, the sealing structure includes a first sealing body and a second sealing body, the first sealing body is at least arranged on a side of the first cover body close to the second cover body; a first sealing rib is arranged on a side of the first sealing body close to the second cover body; the second sealing body is at least arranged on a side of the second cover body close to the first cover body; a second sealing rib is arranged on a side of the second sealing body close to the first cover body; when the box cover is closed on the box body, the first sealing rib and the second sealing rib are staggered along the height direction of the box cover, and the first sealing rib abuts against the second sealing body, and the second sealing rib abuts against the first sealing body.

[0009] Therefore, the first sealing rib and the second sealing rib form double sealing protection at the connecting position of the first cover body and the second cover body, thereby effectively improving the sealing performance at the connecting position of the first cover body and the second cover body, reducing the probability of water leakage at the connecting position of the first cover body and the second cover body, and further improving the sealing performance of the box cover.

[0010] In one of the embodiments, a water retaining platform is provided on one side of the water receiving trough close to the sealing structure; the water retaining platform extends along the length direction of the water receiving trough and is connected to two side walls of the water receiving trough along the length direction.

[0011] Therefore, the water retaining platform can form a barrier to the accumulated water in the water tank, so that the accumulated water in the water tank is discharged through the drainage hole first, reducing the probability of the accumulated water overflowing to the sealing structure, thereby effectively improving the sealing performance at the connection position of the first cover body and the second cover body, reducing the probability of water leakage at the connection position of the first cover body and the second cover body, and further effectively improving the sealing performance of the box cover.

[0012] In one of the embodiments, the first sealing body is provided with first sealing blocks on both sides along the length direction of the water receiving trough, and the second sealing body is provided with second sealing blocks on both sides along the length direction of the water receiving trough; one end of the first sealing block along the width direction of the water receiving trough protrudes toward the second cover body, and the two ends of the first sealing rib are connected to the corresponding first sealing blocks; or, one end of the second sealing block along the width direction of the water receiving trough protrudes toward the first cover body, and the two ends of the second sealing rib are connected to the corresponding second sealing blocks; when the box cover is closed on the box body, the first sealing block abuts against the second sealing block.

[0013] Thus, the sealing performance at the corner where the first cover body and the second cover body are connected can be improved, thereby effectively improving the sealing performance of the box cover.

[0014] In one embodiment, a first groove is provided on a first lid surface where the first lid covers the box body; the first sealing body is annular, and the first sealing body includes a first side body, a second side body, a third side body, and a fourth side body that are connected in sequence. The first side body and the third side body are oppositely arranged, and the second side body and the fourth side body are oppositely arranged. The second side body, the third side body, and the fourth side body are arranged in the first groove, and the first sealing rib is arranged on one side of the first side body close to the second lid; a second groove is provided on a second lid surface where the second lid covers the box body; the second sealing body includes a first sub - part and two second sub - parts connected to both ends of the first sub - part, and a second sealing rib is arranged on one side of the first sub - part close to the first lid; the two second sub - parts are arranged in the second groove; when the box lid covers the box body, the first groove and the second groove enclose an annular slot, and the top of the circumferential side of the box body is inserted into the annular slot and abuts against the first sealing body and the second sub - part respectively;

[0015] And / or, at least one third sealing rib is provided on the first sealing body located in the first groove; when the box lid covers the box body, all the third sealing ribs abut against the inner wall surface of the box body.

[0016] Thereby, the sealing performance when the box lid covers the box body can be improved, so that the stability of the internal environment of the storage box can be improved, and the quality of the items in the storage box can be guaranteed. In addition, by making the first sealing body annular and the second sealing body in the shape of 冖, that is to say, the first lid is provided with a whole - circle sealing body, and the second lid is provided with a partial sealing body. In this way, the sealing performance between the circumferential side of the box lid and the box body and at the connection position between the first lid and the second lid can be improved. At the same time, the usage amount of the sealing body can be reduced, and the cost can be saved.

[0017] In one embodiment, a first convex rib is provided on one side of the first sealing block away from the first sealing body, and the side of the first convex rib away from the first sealing block abuts against the outer groove wall of the first groove; a second convex rib is provided on one side of the second sealing block away from the second sub - part, and the side of the second convex rib away from the second sealing block abuts against the outer groove wall of the second groove; when the box lid covers the box body, the first convex rib and the second convex rib abut against each other.

[0018] Thereby, even when the second lid rotates relative to the first lid, the first convex rib and the second convex rib can still maintain an abutting state, so that the sealing performance at the corner of the connection position between the first lid and the second lid can be further improved, and thus the sealing performance of the box lid can be further improved, so that the stability of the internal environment of the storage box can be guaranteed, and further the quality of the items in the storage box can be guaranteed.

[0019] In one embodiment, at least one first protrusion is disposed in the first groove, a first opening is disposed on at least one of the second side body, the third side body and the fourth side body, and the first protrusion extends into the first opening; at least one second protrusion is disposed in the second groove, a second opening is disposed on at least one of the two second sub-parts, and the second protrusion extends into the second opening;

[0020] And / or, a third groove is provided on the side wall of the first cover body close to the second cover body; the first side body is provided in the third groove; a fourth groove is provided on the side wall of the second cover body close to the first cover body, and the first sub-part is provided in the fourth groove.

[0021] Thus, by the cooperation of the first protrusion and the first opening, the first sealing body can be restricted from sliding in the first groove; by the cooperation of the second protrusion and the second opening, the second sealing body can be restricted from sliding in the second groove, that is, the first sealing body and the second sealing body are circumferentially limited; thereby, the sealing performance when the box cover is closed on the box body and the first cover body and the second cover body are connected can be ensured. In addition, by setting the third groove and the fourth groove, the first sealing body and the second sealing body can be limited in the height direction of the box cover, which can prevent the first sealing body from sliding out of the first groove and the second sealing body from sliding out of the second groove, thereby ensuring the sealing performance when the box cover is closed on the box body and the first cover body and the second cover body are connected.

[0022] In one of the embodiments, the water receiving trough is provided with first recesses on both side walls along the length direction of the water receiving trough; the first recess is located on the side of the drainage hole away from the box body; the connecting part is provided with convex parts on both sides along the length direction of the water receiving trough; the connecting part is provided in the water receiving trough, and the convex part is rotatably engaged in the corresponding first recess so that the connecting part is rotatably connected in the water receiving trough; a notch structure is provided on the connecting part, and the notch structure can allow the two convex parts to move toward each other to disengage from the corresponding first recess.

[0023] Thus, by making the connection part connected to the water receiving groove, the convex part rotates and fits in the corresponding first concave part, so that the second cover body can be rotatably connected to the first cover body. In this way, when taking out items from the box body, the second cover body can be opened without opening and removing the entire box cover; and, because the connection part is connected to the water receiving groove, when the second cover body rotates to the limit angle relative to the first cover body, the second cover body can be inclined relative to the first cover body, and the second cover body can abut against the side wall of the water receiving groove, so that the second cover body can be ensured to be stable in the open state, and the probability of the second cover body accidentally collapsing during the process of storing and retrieving items can be reduced. In addition, by making the connection part provided with a notch structure, the notch structure can allow the two convex parts to move toward each other to disengage from the corresponding first concave part, so that the disassembly and assembly of the second cover body can be facilitated. In this way, when the storage box is in a small space and it is inconvenient to flip the second cover body, the second cover body can be removed with the help of the notch structure to store and retrieve items.

[0024] In one embodiment, the connecting portion includes a connecting sub-portion and two lugs; the connecting sub-portion is arranged on one side of the second cover body; the two lugs are arranged on both sides of the connecting sub-portion along the length direction of the water receiving trough; the two lugs are respectively provided with the convex portions on one side away from the connecting sub-portion; the notch structure includes two first notches, each of the first notches is located between each of the lugs and the connecting sub-portion.

[0025] In this way, the overall structural strength of the connection portion can be improved, while the local strength between the lug and the connection sub-portion can be reduced. In this way, under the action of external force, the two lugs can move toward the corresponding first notches, thereby driving the protrusions to disengage from the corresponding recesses to facilitate the disassembly and assembly of the second cover body.

[0026] A storage box comprises a box body and the box cover described in any of the above embodiments, wherein the box cover is used to cover the box body.

[0027] Thereby, the sealing performance of the storage box can be improved, and the stability of the internal environment of the storage box can be ensured, thereby ensuring the quality of the items in the storage box and improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] Thus, the sealing performance when the box cover 120 is mated with the box body 110 can be improved, thereby improving the stability of the internal environment of the storage box 10 and ensuring the quality of the items in the storage box 10. In addition, by making the first sealing body 123 annular and the second sealing body 124 in the shape of a Chinese character '冖', that is to say, the first cover body 121 is provided with a whole - circle sealing body and the second cover body 122 is provided with a partial sealing body. In this way, the sealing performance between the peripheral side of the box cover 120 and the box body 110 and at the connection position between the first cover body 121 and the second cover body 122 can be improved. At the same time, the usage amount of the sealing body can be reduced, saving costs.

[0074] As Figure 5 、 Figures 15 to 20 As shown, in one embodiment, at least one third sealing rib 1233 is provided on the first sealing body 123 located in the first groove 1216. When the box cover 120 is mated with the box body 110, all the third sealing ribs 1233 abut against the inner wall surface of the box body 110.

[0075] Thus, at least one third sealing rib 1233 can form at least one - layer of sealing protection between the first cover body 121 and the box body 110, thereby improving the sealing performance between the box body 110 and the box cover 120, ensuring the stability of the internal environment of the storage box 10, and ensuring the quality of the items in the storage box 10.

[0076] Specifically, as Figure 5As shown, two third sealing ribs 1233 are arranged on the first sealing body 123 located in the first groove 1216 , and the two third sealing ribs 1233 are arranged at intervals along the height direction of the box cover 120 .

[0077] Thus, double sealing protection can be formed between the first cover 121 and the box body 110, thereby improving the sealing performance when the box cover 120 is closed on the box body 110, ensuring the stability of the internal environment of the storage box 10 and ensuring the quality of the items in the storage box 10.

[0078] like Fig.12 , Fig.13 , Figure 20 to Figure 22 , Fig. 27 , Fig.28 As shown, in one embodiment, a first rib 1232 is provided on a side of the first sealing block 1235 away from the first sealing body 123, and the side of the first rib 1232 away from the first sealing block 1235 abuts against the outer groove wall of the first groove 1216; a second rib 1244 is provided on a side of the second sealing block 1246 away from the second sub-portion 1242, and the side of the second rib 1244 away from the second sealing block 1246 abuts against the outer groove wall of the second groove 1224; when the box cover 120 is closed on the box body 110, the first rib 1232 and the second rib 1244 abut against each other.

[0079] Therefore, even when the second cover body 122 rotates relative to the first cover body 121, the first rib 1232 and the second rib 1244 can still maintain an abutment state, thereby further improving the sealing of the corner where the first cover body 121 and the second cover body 122 are connected, thereby further improving the sealing of the box cover 120, ensuring the stability of the internal environment of the storage box 10, and further ensuring the quality of the items in the storage box 10.

[0080] Specifically, Fig.21 , Fig. 22 , Fig. 27 , Fig.28 As shown, one end of the first rib 1232 close to the second cover body 122 is shorter than one end of the first sealing block 1235 close to the second cover body 122, and one end of the second rib 1244 close to the first cover body 121 is longer than one end of the second sealing block 1246 close to the first cover body 121; in this way, when the box cover 120 is closed on the box body 110, the abutting position of the first sealing block 1235 and the second sealing block 1246 and the abutting position of the first rib 1232 and the second rib 1244 are staggered along the width direction of the water receiving groove 1211, thereby further improving the sealing performance of the corner where the first cover body 121 and the second cover body 122 are connected, thereby further improving the sealing performance of the box cover 120.

[0081] like Fig.12 , Fig.13 , Fig.21 , Fig. 22 As shown, specifically, the first convex rib 1232 is L-shaped in the first groove 1216, and the second convex rib 1244 is L-shaped in the second groove 1224. In this way, when the side wall of the box body 110 is inserted into the first groove 1216 and the second groove 1224, the first convex rib 1232 and the first sealing block 1235 are distributed on both sides of the side wall of the box body 110, the first convex rib 1232 abuts against the outer wall surface of the box body 110, and the first sealing block 1235 abuts against the inner wall surface of the box body 110; the second convex rib 1232 is L-shaped in the second groove 1224. 44 and the second sealing block 1246 are distributed on both sides of the side wall of the box body 110, the second rib 1244 abuts against the outer wall surface of the box body 110, and the second sealing block 1246 abuts against the inner wall surface of the box body 110, thereby improving the sealing between the first cover body 121 and the box body 110 near the corner and between the second cover body 122 and the box body 10, thereby further improving the sealing of the storage box 10, ensuring the stability of the internal environment of the storage box 10, and further ensuring the quality of the items in the storage box 10.

[0082] like Figures 14 to 19 , Fig. 20 , Figure 26 to Figure 28 As shown, in one embodiment, at least one first protrusion 125 is arranged in the first groove 1216, and a first opening 1234 is arranged on at least one of the second side body 123b, the third side body 123c and the fourth side body 123d, and the first protrusion 125 extends into the first opening 1234; at least one second protrusion 126 is arranged in the second groove 1224, and a second opening 1245 is arranged on at least one of the two second sub-parts 1242, and the second protrusion 126 extends into the second opening 1245.

[0083] Therefore, by arranging at least one first protrusion 125 in the first groove 1216, a first opening 1234 is arranged on at least one of the second side body 123b, the third side body 123c and the fourth side body 123d, at least one second protrusion 126 is arranged in the second groove 1224, and a second opening 1245 is arranged on at least one of the two second sub-parts 1242, so that the first protrusion 125 extends into the first opening 1234; the second protrusion 126 extends into the second opening 1245, thereby limiting the first sealing body 123 from sliding in the first groove 1216 and limiting the second sealing body 124 from sliding in the second groove 1224, that is, the first sealing body 123 and the second sealing body 124 are circumferentially limited.

[0084] like Figures 16 to 20As shown, specifically, there may be two first protrusions 125 and two first openings 1234. The two first protrusions 125 are arranged opposite to each other in the first groove 1216 along the length direction of the water receiving tank 1211, and the two first openings 1234 are arranged on the second side body 123b and the fourth side body 123d respectively. Figure 23 to Figure 25 As shown, there may be two second protrusions 126 and two second openings 1245 . The two second protrusions 126 are arranged opposite to each other in the second groove 1224 along the length direction of the water receiving trough 1211 , and the two second openings 1245 are respectively arranged on the two second sub-portions 1242 .

[0085] like Fig.11 , Figures 14 to 20 , Fig.21 , Figure 25 to Figure 28 As shown, in one embodiment, a third groove 1217 is provided on the side wall of the first cover body 121 close to the second cover body 122; the first side body 123a is provided in the third groove 1217; a fourth groove 1225 is provided on the side wall of the second cover body 122 close to the first cover body 121, and the first sub-portion 1241 is provided in the fourth groove 1225.

[0086] It can be understood that the third groove 1217 is open at both ends along the length direction of the water receiving trough 1211, and the fourth groove 1225 is open at both ends along the length direction of the water receiving trough 1211; thereby, the first side body 123a can be conveniently arranged in the third groove 1217, and the first sub-portion 1241 can be arranged in the fourth groove 1225, so as to facilitate the installation of the first sealing body 123 and the second sealing body 124; at the same time, the third groove 1217 can limit the first side body 123a in the height direction of the box cover 120, and the fourth groove 1225 can limit the first sub-portion 1241 in the height direction of the box cover 120, so as to avoid the first sealing body 123 from sliding out of the first groove 1216 and the second sealing body 124 from sliding out of the second groove 1224, thereby ensuring the sealing when the box cover 120 is closed on the box body 110 and the connection position between the first cover body 121 and the second cover body 122.

[0087] like Fig.10 , Figures 11 to 16 , Figure 20 to Figure 24As shown, in one of the embodiments, the water receiving groove 1211 is respectively provided with a first recess 1212 on both side walls along the length direction thereof; the first recess 1212 is located on the side of the drainage hole 1215 away from the box body 110; the connecting portion 1221 is respectively provided with a protrusion 1222 on both sides along the length direction of the water receiving groove 1211; the connecting portion 1221 is provided in the water receiving groove 1211, and the protrusion 1222 is rotatably matched in the corresponding first recess 1212, so that the connecting portion 1221 is rotatably provided in the water receiving groove 1211; a notch structure 1223 is provided on the connecting portion 1221, and the notch structure 1223 can allow the two protrusions 1222 to move toward each other to disengage from the corresponding first recess 1212.

[0088] Thus, by connecting the connecting portion 1221 to the water receiving groove 1211, the convex portion 1222 is rotatably matched in the corresponding first concave portion 1212, so that the second cover 122 can be rotatably connected to the first cover 121. In this way, when taking out items from the box 110, it is sufficient to open the second cover 122 without opening and removing the entire box cover 120; and, since the connecting portion 1221 is arranged in the water receiving groove 1211, when the second cover 122 is rotated to the limit angle relative to the first cover 121, the second cover 122 can be arranged to be inclined relative to the first cover 121, and the second cover 122 can abut against the side wall of the water receiving groove 1211, so that the second cover 122 can be ensured to be stable in the open state, reducing the probability of the second cover 122 accidentally collapsing during the process of taking out items. In addition, by providing a notch structure 1223 on the connecting portion 1221, the notch structure 1223 can allow the two protrusions 1222 to move toward each other to disengage from the corresponding first recessed portions 1212, thereby facilitating the assembly and disassembly of the second cover body 122. In this way, when the storage box 10 is in a narrow space and it is inconvenient to flip the second cover body 122, the second cover body 122 can be removed with the aid of the notch structure 1223 to facilitate the storage and retrieval of items.

[0089] like Fig.23 , Fig.24 As shown, in one embodiment, the connecting portion 1221 includes a connecting sub-portion 1221a and two lugs 1221b; the connecting sub-portion 1221a is arranged on one side of the second cover body 122; the two lugs 1221b are arranged on both sides of the connecting sub-portion 1221a along the length direction of the water receiving trough 1211; the two lugs 1221b are respectively provided with protrusions 1222 on the side away from the connecting sub-portion 1221a; the notch structure 1223 includes two first notches 1223a, and each first notch 1223a is located between each lug 1221b and the connecting sub-portion 1221a.

[0090] Therefore, by setting the connecting sub-portion 1221a on one side of the second cover body 122; two lugs 1221b are set on both sides of the connecting sub-portion 1221a along the length direction of the water receiving groove 1211; the two lugs 1221b are respectively provided with convex portions 1222 on the side away from the connecting sub-portion 1221a, so that the overall structural strength of the connecting portion 1221 can be improved; by setting a first notch 1223a between each lug 1221b and the connecting sub-portion 1221a, the local strength between the lug 1221b and the connecting sub-portion 1221a can be reduced, so that under the action of external force, the two lugs 1221b can move toward the corresponding first notch 1223a, thereby driving the convex portion 1222 to disengage from the corresponding recessed portion, so as to facilitate the disassembly and assembly of the second cover body 122.

[0091] It is understandable that the convex portion 1222 may be an axis-shaped structure, and the end of the convex portion 1222 may be an arc surface, so that the convex portion 1222 can be easily rotated and fitted into the concave portion.

[0092] like Figures 14 to 16 As shown, in one embodiment, the first cover body 121 is provided with openings 1213 on both sides along the length direction of the water receiving groove 1211 , respectively. The openings 1213 extend along the length direction of the water receiving groove 1211 and communicate with the first recess 1212 .

[0093] Therefore, the lug 1221b together with the convex portion 1222 thereon can be conveniently driven to move toward the first notch 1223a through the opening 1213, so that the convex portion 1222 is separated from the corresponding first concave portion 1212, thereby facilitating the disassembly and assembly of the second cover body 122.

[0094] like Figures 14 to 16 As shown, in one embodiment, two second recesses 1214 are provided on the first cover 121 , and the two second recesses 1214 are distributed on both sides of the length direction of the water receiving trough 1211 and are located above the corresponding first recesses 1212 .

[0095] Therefore, when the second cover body 122 is connected to the first cover body 121, the two second recesses 1214 can play a guiding role, and the two protrusions 1222 on the connecting part 1221 can slide along the two second recesses 1214 into the water receiving groove 1211, so that the connecting part 1221 is provided with the water receiving groove 1211, and the protrusions 1222 on both sides of the connecting part 1221 are rotatably matched with the corresponding first recesses 1212, thereby realizing the rotational connection between the first cover body 121 and the second cover body 122.

[0096] like Figures 4 to 8As shown, in one embodiment, the first cover body 121 is fixed to the box body 110 by a first snap-fit ​​structure 128, and the first snap-fit ​​structure 128 includes a first snap-fit ​​groove 1281 and a first snap-fit ​​protrusion 1282 that snap-fit ​​with each other; the first snap-fit ​​groove 1281 is arranged on one of the first cover body 121 and the box body 110, and the snap-fit ​​protrusion is arranged on the other of the first cover body 121 and the box body 110; the side of the second cover body 122 away from the first cover body 121 is fixed to the box body 110 by a second snap-fit ​​structure 129, and the second snap-fit ​​structure 129 includes a second snap-fit ​​groove 1291 and a second snap-fit ​​protrusion 1292 that snap-fit ​​with each other; the second snap-fit ​​groove 1291 is arranged on one of the second cover body 122 and the box body 110, and the second snap-fit ​​protrusion 1292 is arranged on the other of the second cover body 122 and the box body 110.

[0097] Therefore, by providing the first snap-fit ​​structure 128 and the second snap-fit ​​structure 129 , the fixed connection between the first cover 121 and the box body 110 and the fixed connection between the second cover 122 and the box body 110 can be conveniently achieved.

[0098] It is understandable that if Figure 5 As shown, the box body 110 is provided with a plurality of first card grooves 1281 on both sides along the length direction of the water receiving groove 1211, and the plurality of first card grooves 1281 are arranged at intervals along the width direction of the water receiving groove 1211, and the first cover body 121 is provided with a plurality of first card protrusions 1282 on both sides along the length direction of the water receiving groove 1211, and the plurality of first card protrusions 1282 are arranged at intervals along the width direction of the water receiving groove 1211; specifically, the box body 110 is provided with three first card grooves 1281 on both sides along the length direction of the water receiving groove 1211, and the first cover body 121 is provided with two first card protrusions 1282 on both sides along the length direction of the water receiving groove 1211; in this way, the first cover body 121 can be assembled on both ends of the box body 110.

[0099] like Figures 6 to 8 As shown, the box body 110 is respectively provided with a first latching protrusion 1282 and a second latching protrusion 1292 on both sides along the width direction of the water receiving groove 1211, a first latching groove 1281 is provided on the side of the first cover body 121 away from the second cover body 122, and a second latching groove 1291 is provided on the side of the second cover body 122 away from the first cover body 121.

[0100] The first latching protrusion 1282 and the second latching protrusion 1292 may have the same structure, both of which may be convex structures; the first latching groove 1281 and the second latching groove 1291 may have the same structure, both of which may be groove structures adapted to the convex structures.

[0101] like Figure 8As shown, in one embodiment, a ridge 1293 is provided on the side of the second cover 122 away from the first cover 121 , and the end of the ridge 1293 is an inclined surface. When the second cover 122 is covered on the box body 110 , the ridge 1293 abuts against the inner wall surface of the box body 110 .

[0102] Thus, when the second cover 122 is fixedly connected to the box 110 through the second buckle structure 129, the convex strip 1293 abuts against the inner wall surface of the box 110, so that the second cover 122 can be well fixed on the box 110. In addition, the end surface of the convex strip 1293 is an inclined surface, which plays a guiding role when the second cover 122 is covered on the box 110, so that the convex strip 1293 can slide into the box 110 and abut against the inner wall surface of the box 110.

[0103] It is understandable that there may be a plurality of convex strips 1293, and the plurality of convex strips 1293 are arranged at intervals along the length direction of the water receiving groove 1211. Specifically, there may be two convex strips 1293.

[0104] Second, see Figures 1 to 7 An embodiment of the utility model provides a storage box 10, comprising a box body 110 and a box cover 120 in any of the above embodiments, the box cover 120 is used to cover the box body 110. Thus, the sealing performance of the storage box 10 can be improved, the stability of the internal environment of the storage box 10 can be ensured, and the quality of the items in the storage box 10 can be ensured, and the user experience can be improved.

[0105] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
