Description

Technical Field

[0001] The present invention relates to the technical field of storage tools, and in particular to a storage box. Background Art

[0002] Personal items that require high hygiene conditions, such as dentures and braces, need to be stored when not in use. In addition, these personal items also need to be stored when traveling or on a business trip. Generally, storage boxes are usually used to store these personal items.

[0003] In addition, since these frequently used personal items may be contaminated with dust and breed bacteria, they also need to be cleaned or disinfected frequently. Then, the cleaned or disinfected items are stored in a storage box. In addition, for products such as dentures that require a longer time to be soaked and cleaned, it is necessary to carry a special disinfection device when traveling or on a business trip. Therefore, the number of boxes that users need to carry increases.

[0004] For this reason, some storage boxes for storing personal items such as dentures are directly filled with clean water, disinfectant, etc., so that these personal items can be disinfected while being stored. However, although the gaps between the shell and the first cover of these storage boxes are sealed, liquid will still seep out of these gaps when they are carried, causing other items to get wet. Alternatively, in the event of an accidental fall, the shell and the first cover will open to each other, causing the liquid in the storage box to spill. Utility Model Content

[0005] The utility model aims at one of the above technical problems and proposes a storage box, which can improve the sealing performance of the gap between the shell and the first cover.

[0006] A storage box according to one aspect of the utility model comprises:

[0053] Embodiments of the present embodiment are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present embodiment, and should not be construed as limiting the present embodiment.

[0054] In the description of this embodiment, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this embodiment.

[0055] In the description of this embodiment, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0056] In the description of this embodiment, 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 this embodiment based on the specific content of the technical solution.

[0057] In the conventional storage boxes, there is a scheme in which a sealing ring is bonded to the ends of the housing and the cover of the storage box to seal the gap between the housing and the cover when the storage box is closed. When the housing and the first cover are closed, the sealing ring is squeezed to seal the gap between the housing and the first cover.

[0058] In conventional storage boxes, the shell and the cover body usually clamp the sealing ring in the relative direction (hereinafter referred to as the "first direction" for ease of explanation) when they are covered with each other, so as to deform the sealing ring. However, when the sealing ring is clamped, the sealing ring will deform in both radial directions. In addition, the shell and the first cover body themselves will also deform due to uneven force when they are covered, and the deformation may be greater due to the thin thickness of the first cover body. Therefore, a gap will be generated between the deformed sealing ring and the end faces of the shell and / or the cover body, which will also deform, instead of completely fitting the end faces of the shell and / or the cover body.

[0059] When the storage box is carried, it may be shaken, collided, or overturned. In this case, liquids such as clean water and disinfectant stored in the storage box may seep to the outside through these tiny gaps.

[0060] The following reference Figures 1 to 22 , describing the storage box of this embodiment.

[0061] Reference Figures 4 to 6 , and auxiliary reference Figures 1 to 3 Compared with the previous storage boxes, the storage box of this embodiment can improve the sealing of the gap between the shell 101 and the cover. Specifically, the storage box of this embodiment includes: a shell 101, a cover (for the convenience of distinction, the cover directly covered or opened relative to the shell 101 will be referred to as "the first cover 102" later), a locking portion 103 and a sealing member 104. The shell 101 is formed with a first storage cavity 105. The shell 101 has a first end 106, which is a portion located at the opening end of the first storage cavity 105. The first cover 102 can be covered or opened relative to the shell 101. The first cover 102 has a second end 107, and in the state of covering with the shell 101, the first end 106 and the second end 107 are opposite in a first direction. The locking portion 103 is locked and can be released in a manner that the shell 101 and the first cover 102 cover each other, and in the released state, the shell 101 and the first cover 102 can be opened from each other. The sealing member 104 is arranged to be sandwiched between the first end 106 and the second end 107 when the housing 101 and the first cover 102 are covered with each other and surround the first receiving chamber 105. The sealing member 104 is formed with an inclined portion 108 inclined relative to the first direction (see auxiliary reference). Fig.10 ). At least one of the first end portion 106 and the second end portion 107 is formed with a contact portion 109 (see Fig. 9 ), when the housing 101 and the first cover 102 are locked by the locking portion 103 and cover each other, the abutting portion 109 abuts against the inclined portion 108.

[0062] In the storage box of the embodiment, since the seal 104 has an inclined portion 108 inclined relative to the direction in which the housing 101 and the first cover 102 overlap each other, that is, the first direction, when the housing 101 and the first cover 102 overlap each other, the abutment portion 109 formed at one of the first end 106 and the second end 107 abuts against the inclined portion 108 from a direction intersecting with the first direction, rather than abutting against the inclined portion 108 in parallel with the first direction. In this way, on the one hand, the influence of a slight deformation of the housing 101 and the first cover 102 when overlapping along the first direction on the seal 104 can be reduced, and a gap between the seal 104 and the housing 101 and the first cover 102 can be suppressed. On the other hand, since the inclined portion 108 has a certain height relative to the gap between the covering position of the shell 101 and the first cover body 102, it will not only extend the sealing path of the seal 104, but also increase the difficulty of the liquid crossing this height. Therefore, it is possible to further suppress the liquid in the first storage chamber 105 from seeping to the outside through the inclined portion 108 of the seal 104.

[0063] Thus, the storage box of this embodiment can improve the sealing performance between the housing 101 and the first cover 102, and can more effectively prevent the liquid in the storage box from seeping to the outside.

[0064] Reference Figures 7 to 9 The shell 101 has a first bottom wall 110 and a first peripheral wall 111, and the first peripheral wall 111 and the first bottom wall 110 are integrally formed. In a top view, the first peripheral wall 111 can be circular, roughly square, triangular, other polygonal, and various irregular shapes. Here, for the sake of convenience, the first peripheral wall 111 is roughly square in shape when viewed from above. In other words, the overall appearance of the storage box is roughly cubic. The first peripheral wall 111 protrudes from the edges of the first bottom wall 110, and thus, the first peripheral wall 111 and the first bottom wall 110 jointly define the first storage cavity 105.

[0065] The first end 106 of the shell 101 is formed at one end of the first peripheral wall 111 away from the first bottom wall 110. The thickness of the first peripheral wall 111 at the first end 106 is greater than the thickness of other parts. The inner side surface of the first peripheral wall 111 (also referred to as the "first inner side surface 112" for ease of distinction) extends roughly smoothly, and the outer side surface of the first peripheral wall 111 (also referred to as the "first outer side surface 113" for ease of distinction) at the first end 106 extends outward while extending upward compared to other parts. As a result, the overall width of the end surface of the first peripheral wall 111 (also referred to as the "first end surface 114" for ease of distinction) is greater than the width of other parts of the first peripheral wall 111. It should be noted that in this specification, "inside" refers to the side of the first storage cavity 105 facing the storage box, and "outside" refers to the side facing the outside of the storage box.

[0066] Main reference Fig. 9 , and auxiliary reference Figure 5 as well as Figure 6 , the abutment portion 109 is formed at the first end portion 106 of the shell 101 and extends along the circumference of the first end portion 106. The abutment portion 109 protrudes upward from the first end surface 114 of the first peripheral wall 111. In a top view, the abutment portion 109 is also in a ring shape surrounding the first storage chamber 105. The inner side surface (for the convenience of distinction, also referred to as the "second inner side surface 115") and the outer side surface (for the convenience of distinction, also referred to as the "second outer side surface 116") of the abutment portion 109 are inclined surfaces respectively. The second inner side surface 115 of the abutment portion 109 is adjacent to the first inner side surface 112 of the first peripheral wall 111, and extends upward from the upper part of the second inner side surface 115 of the first peripheral wall 111 while tilting outward. The second outer side surface 116 of the abutment portion 109 extends upward from the first end surface 114 of the first end portion 106 while tilting inward. The top of the second inner side surface 115 and the top of the second outer side surface 116 of the abutting portion 109 are connected by an arc-shaped connecting surface. Thus, the abutting portion 109 is formed to gradually decrease in width from the base end connected to the first end surface 114 toward the distal end. In other words, the cross-section of the abutting portion 109 is roughly in the shape of an inverted "V". In addition, the angle formed by the second inner side surface 115 and the second outer side surface 116 of the abutting portion 109 relative to each other (for ease of distinction, also referred to as "first angle R1") is an acute angle, and the range of the angle is, for example, greater than 5° and less than 15°.

[0067] Reference Figure 7 , and auxiliary reference Figure 5 as well as Figure 1 A first hinge seat 117 is formed on one side of the circumference of the shell 101, and the first hinge seat 117 is formed on one side of the first circumferential wall 111 of the shell 101 located at the first end 106. The first hinge seat 117 is located on one side of the radial direction of the shell 101. It should be noted that "radial" should be understood in a broad sense, that is, when a three-dimensional component is cross-sectioned, the extension direction of the cross section is radial. The first hinge seat 117 is formed with a first hinge hole 118 that penetrates in a direction parallel to the side of the first circumferential wall 111 (that is, the side of the first circumferential wall 111 that forms the first hinge seat 117). The axis of the first hinge hole 118 is higher than the first end face 114 of the first end 106 along the first direction. The axis of the first hinge hole 118 is higher than the first end face 114 of the first end 106 along the first direction, for example, by more than 0.1 mm and less than 0.5 mm. The first hinge seat 117 is a part of a first hinge portion 119 to be described later, and is used for hinge connection with the first cover body 102 .

[0068] A second hinge seat 120 is formed on the other side of the circumference of the housing 101. The second hinge seat 120 is formed on the other side of the first circumferential wall 111 of the housing 101 located at the first end 106. That is, the second hinge seat 120 is located on the other side of the radial direction of the housing 101, and is opposite to the first hinge seat 117 in the radial direction of the housing 101 across the first receiving chamber 105. The second hinge seat 120 is formed with a second hinge hole 121 extending along the side parallel to the first circumferential wall 111 (similarly, also parallel to the axis of the first hinge hole 118). The second hinge hole 121 is an open hole, that is, a first connecting groove 122 is formed in the second hinge seat 120, and the first connecting groove 122 opens the second hinge hole 121 radially to the outside along the radial direction of the second hinge hole 121. The width of the first connecting groove 122 is smaller than the inner diameter of the second hinge hole 121. The axis of the second hinge hole 121 is lower than the first end surface 114 of the first end portion 106 along the first direction. The axis of the second hinge hole 121 is lower than the first end surface 114 of the first end portion 106 along the first direction, for example, by 3 mm or more and 6 mm or less. In addition, the distance between the axis of the second hinge hole 121 and the outer side of the portion of the first peripheral wall 111 forming the second hinge seat 120 is, for example, 3 mm or more and 6 mm or less.

[0069] Main reference Fig.11 , Fig.12 And auxiliary reference Figure 4 as well as Figure 5 , the first cover body 102 has a second bottom wall 123 and a second peripheral wall 124, and the second peripheral wall 124 and the second bottom wall 123 are integrally formed. In a top view, the shape of the periphery of the first cover body 102 roughly matches the shape of the periphery of the housing 101, thereby forming a storage box in which the housing 101 and the first cover body 102 are smoothly covered at the covering position (i.e., the position where the first end 106 and the second end 107 are roughly in contact) in the covered state. The size of the periphery of the second bottom wall 123 is smaller than the size of the first storage cavity 105. When the housing 101 and the first cover body 102 cover each other, part of the second bottom wall 123 is stored in the first storage cavity 105. The second bottom wall 123 has a plate-like portion 125 and a first connecting portion 126, the plate-like portion 125 is roughly flat, and the first connecting portion 126 is annular in a bottom view, and extends upward from the edges of the plate-like portion 125, roughly perpendicular to the plate-like portion 126. Taking the state where the first cover 102 and the housing 101 cover each other as an example, the first connection portion 126 extends from the edges of the plate-shaped portion 125 along the first direction in the direction opposite to the housing 101. A relief portion 127 is formed on one side of the second bottom wall 123, and the relief portion 127 is a substantially rectangular notch that is recessed upward relative to the second bottom wall 123.

[0070] The second peripheral wall 124 is formed around the outer side of the second bottom wall 123. The bottom of the second peripheral wall 124 is higher than the plate-like portion 125 of the second bottom wall 123. If the state in which the first cover 102 and the housing 101 cover each other is used as an example for explanation, the bottom of the second peripheral wall 124 is located at a position higher than the first end surface 114 of the first end portion 106 of the housing 101 along the first direction, and the plate-like portion 125 of the second bottom wall 123 is located at a position lower than the first end surface 114 of the first end portion 106 of the housing 101 along the first direction. The second peripheral wall 124 is connected to the first connecting portion 126 of the second bottom wall 123 through the second connecting portion 128, and the second connecting portion 128 is higher than the bottom of the second peripheral wall 124. As a result, a gap is formed between the second peripheral wall 124 and the first connecting portion 126 via the second connecting portion 128, and the gap also serves as a mounting groove 129 for mounting the seal 104. The form of the second connection portion 128 is not particularly limited. For example, the second connection portion 128 may be rib-shaped, and the second connection portion 128 includes a plurality of ribs, which are spaced apart along the circumference of the second peripheral wall 124 and the first connection portion 126. When the second peripheral wall 124 and the first connection portion 126 are provided with a mounting groove 129 via the second connection portion 128, the inner side surface of the second peripheral wall 124 (also referred to as the "third inner side surface 130" for the convenience of distinction) and the outer side surface of the first connection portion 126 (also referred to as the "third outer side surface 131" for the convenience of distinction) are opposite. The third inner side surface 130 extends toward the top direction of the first cover body 102 and is inclined toward one side of the first connection portion 126. The third outer side surface 131 extends toward the top direction of the first cover body 102 and is inclined toward one side of the second peripheral wall 124. Therefore, the cross-section of the mounting groove 129 defined by the third inner side surface 130 of the second peripheral wall 124 , the second connecting portion 128 , and the third outer side surface 131 of the first connecting portion 126 is substantially trapezoidal.

[0071] The second end 107 of the first cover 102 is formed on the bottom side of the second peripheral wall 124. In other words, the mounting groove 129 defined by the second peripheral wall 124, the second connecting portion 128 and the first connecting portion 126 is formed at the second end 107. In addition, the second end 107 of the first cover 102 is higher than the plate-shaped portion 125 of the second bottom wall 123 of the first cover 102. That is, the second end 107 of the first cover 102 is closer to the top of the first cover 102 relative to the plate-shaped portion 125 of the second bottom wall 123. The end face of the second end 107 (also referred to as "second end face 132" for the convenience of distinction) is roughly planar. When the first cover 102 and the housing 101 are covered with each other, the second end face 132 of the second end 107 and the first end face 114 of the first end 106 are opposite to each other with a slight gap therebetween. When viewed from a bottom perspective, the mounting groove 129 is in the shape of a closed loop extending along the circumference of the second end portion 107 , and surrounds the outer side of the second bottom wall 123 .

[0072] A third hinge seat 133 is formed on one side of the circumference of the first cover 102, and the third hinge seat 133 is formed on one side of the second peripheral wall 124 of the first cover 102 located at the second end 107. The third hinge seat 133 is located on one side of the radial direction of the first cover 102. The third hinge seat 133 is formed with a third hinge hole 134 that penetrates along the side parallel to the second peripheral wall 124 (i.e., the side of the second peripheral wall 124 formed with the third hinge seat 133). If the state in which the first cover 102 and the housing 101 are covered with each other is used as an example for explanation, the axis of the third hinge hole 134 is lower than the second end face 132 of the second end 107 along the first direction. The axis of the second hinge hole 121 is higher than the second end face 132 of the second end 107 along the first direction, for example, by more than 0.3 mm and less than 1 mm. The third hinge seat 133 is used to be hinged with the first hinge seat 117 of the housing 101 as a part of the first hinge portion 119 described later.

[0073] A first stopper 135 is formed on the other side of the circumference of the first cover 102, and the first stopper 135 is formed on the other side of the second peripheral wall 124 of the housing 101 located at the second end 107. That is, the first stopper 135 is located on the other side of the radial direction of the first cover 102, and is opposite to the third hinge seat 133 in the radial direction of the first cover 102 across the second bottom wall 123. The first stopper 135 has a first arm portion 136 as a base end and a second arm portion 137 as a distal end. The first arm portion 136 extends outward from the edge of the outer periphery of the first cover 102 in a manner substantially parallel to the second end surface 132 of the second end 107. The second arm portion 137 protrudes upward from the cantilever end of the first arm portion 136 compared to the first arm portion 136. A stopper surface 138 is formed on the upper surface of the first arm portion 136. If the state in which the first cover 102 and the housing 101 cover each other is used as an example for explanation, the stop surface 138 is higher than the second end surface 132 of the second end portion 107 along the first direction. In other words, the stop surface 138 is higher than the axis of the first hinge hole 118 of the first hinge seat 117 of the housing 101 along the first direction. The stop surface 138 is higher than the axis of the first hinge hole 118 along the first direction, for example, by less than 10 mm, and can be higher by, for example, more than 3 mm and less than 7 mm.

[0074] Among the four edges of the first cover body 102, the middle area along the direction opposite to the third hinge seat 133 and the first stop seat 135 (for the convenience of distinction, also referred to as the "first area 139" (refer to Fig.12 The strength of the portion in the dotted line frame is greater than the strength of the two sides of the first cover 102, namely, the edge located on one side of the third hinge seat 133 and the edge located on one side of the first locking seat 135.

[0075] The method for making the first region 139 of the first cover 102 stronger than other edge regions is not particularly limited.

[0076] For example, in the first region 139 of the first cover 102, the thickness of the rib-shaped second connection portion 128 connecting the second peripheral wall 124 and the first connection portion 126 can be greater than the thickness of the second connection portion 128 in other edge regions. Alternatively, in the first region 139, the second connection portion 128 is directly formed in a block shape and connects the second peripheral wall 124 and the first connection portion 126.

[0077] For example, in addition to forming the second connecting portion 128 of different thicknesses in the first area 139, the thickness of the second peripheral wall 124 and / or the thickness of the first connecting portion 126 in the first area 139 can also be greater than the thickness of the second peripheral wall 124 and / or the thickness of the first connecting portion 126 in other edge areas.

[0078] In addition, the strength of the material of the second connection portion 128 in the first region 139 may be greater than that of the material of the second connection portion 128 in other edge regions. For example, when the first cover 102 is injection molded by resin or the like, the second connection portion 128 in the first region 139 may be made of a metal material such as aluminum alloy, copper alloy, stainless steel, 45# steel, etc., which is stronger than the resin, and may be integrally molded with the first cover 102 by, for example, insert molding.

[0079] A second storage cavity 140 is formed at the top of the first cover body 102, and the second storage cavity 140 is defined by the plate-like portion 125 of the second bottom wall 123 and the first connecting portion 126. A fourth hinge hole 141 is formed on the first cover body 102 above the third hinge seat 133. The axis of the fourth hinge hole 141 is parallel to the axis of the third hinge hole 134. The fourth hinge hole 141 is a part of the second hinge portion 142, and is used to be hinged with the fourth hinge seat 144 of the second cover body 143 described later. A first magnet 145 is embedded on the inner side of the second peripheral wall 124, and the first magnet 145 is embedded on the side opposite to the position where the fourth hinge hole 141 is formed, separated by the second storage cavity 140.

[0080] Continue to refer to Figure 3 , Figure 4 The storage box further includes a second cover 143, which is mounted to the first cover 102 and can be closed or opened relative to the second storage cavity 140. The second cover 143 is roughly formed in the shape of a flat plate. A fourth hinge seat 144 is formed on one side of the edge of the second cover 143, and the fourth hinge seat 144 is located on one side of the radial direction of the second cover 143. The fourth hinge seat 144 is formed with a fifth hinge hole 146 that passes through the side parallel to the second cover 143. The fourth hinge seat 144 is a part of the second hinge portion 142 described later, and is used to be hinged with the fourth hinge hole 141 of the first cover 102 mentioned above. A second magnet 147 is embedded on the other side of the edge of the second cover 143. When the second cover 143 covers the second storage cavity 140, the second magnet 147 and the first magnet 145 are attracted to each other.

[0081] Continue to refer to Figure 5 , Figure 6 as well as Fig.10 , and auxiliary reference Fig.12As described above, the seal 104 is arranged to be sandwiched between the first end 106 and the second end 107 and surround the first storage cavity 105 when the housing 101 and the first cover 102 are covered with each other. The seal 104 is formed with an inclined portion 108 inclined relative to the first direction. At least one of the first end 106 and the second end 107 is formed with an abutment portion 109, and when the housing 101 and the first cover 102 are locked by the locking portion 103 and covered with each other, the abutment portion 109 abuts against the inclined portion 108.

[0082] The seal 104 is disposed at the second end 107 of the first cover 102. The seal 104 is annular and is installed in the installation groove 129 formed at the second end 107. The height from the bottom to the top of the seal 104 is the same as the depth of the installation groove 129, or slightly greater than the depth of the installation groove 129. For example, the height from the bottom to the top of the seal 104 is greater than the depth of the installation groove 129 by more than 0 mm and less than 0.3 mm. In other words, after the seal 104 is installed in the installation groove 129, the seal 104 is substantially flush with the second end face 132 of the second end 107, or the height exposed from the second end face 132 of the second end 107 is less than 0.3 mm. In addition, the height of the portion of the seal 104 exposed from the second end face 132 of the second end 107 is less than the gap between the second end face 132 of the second end 107 and the first end face 114 of the first end 106 when the first cover 102 and the housing 101 are covered with each other.

[0083] The seal 104 has a planar bottom surface 148, and when installed in the installation groove 129, the bottom surface 148 is in contact with the second connection portion 128. The seal 104 has two side surfaces (referred to as "fourth inner side surface 149" and "fourth outer side surface 150" for easy distinction), and the fourth inner side surface 149 and the fourth outer side surface 150 are formed to be gradually inclined from the top (the side where the inclined portion 108 is formed) to the bottom (the side abutting the second connection portion 128), that is, the outer periphery of the cross section of the seal 104 is generally trapezoidal. When installed in the installation groove 129, the fourth inner side surface 149 of the seal 104 is opposite to the third outer side surface 131 of the first connection portion 126, and the fourth outer side surface 150 of the seal 104 is opposite to the third inner side surface 130 of the second peripheral wall 124. In addition, the width of the installation groove 129 is slightly larger than the width of the seal 104 as a whole, so that after the seal 104 is installed in the installation groove 129, there is a gap relative to the installation groove 129. That is, there is a gap between the fourth inner side surface 149 of the seal 104 and the third outer side surface 131 of the first connecting portion 126, and / or between the fourth outer side surface 150 of the seal 104 and the third inner side surface 130 of the second peripheral portion.

[0084] The seal 104 has a first receiving groove 151 formed on one side of the top across the entire length. Two opposing inclined portions 108 are formed in the first receiving groove 151, and the two inclined portions 108 are formed so that the cross-section of the first receiving groove 151 gradually decreases from the opening of the first receiving groove 151 toward the bottom width of the first receiving groove 151. The first receiving groove 151 is formed by being recessed from the approximately middle portion 157 of the top surface of the seal 104 toward the bottom side. Arc-shaped guide angles 152 are formed between the two inclined portions 108 and the top surface of the seal 104, respectively. The guide angles 152 provide a smooth transition between the first receiving groove 151 and the top surface. In addition, the guide angles 152 are used to expand the opening of the first receiving groove 151 to a certain extent. The angle formed by the two inclined portions 108 relative to each other (for ease of distinction, also referred to as the "second angle R2") is an acute angle, and the range of the angle is, for example, greater than 5° and less than 15°. In addition, the size of the second angle R2 formed by the two inclined portions 108 is substantially the same as the size of the first angle R1 formed by the second inner side surface 115 and the second outer side surface 116 of the abutment portion 109. Alternatively, the second angle R2 is slightly smaller than the first angle R1. In addition, the width of the opening end of the first receiving groove 151 is substantially the same as the width of the base end of the abutment portion 109 connected to the first end surface 114, and the height of the abutment portion 109 is slightly greater than the depth of the first receiving groove 151.

[0085] The following describes the installation, closing, and opening methods of the housing 101 and the first cover 102 of the storage box.

[0086] Continue to refer to Figure 7 , Fig.11 as well as Figure 1 , Figure 5 The shell 101 and the first cover 102 are connected to each other through the first hinge 119. The first hinge 119 of the storage box for connecting the shell 101 and the first cover 102 is formed on one side of the circumference. The first hinge 119 includes: the first hinge seat 117 formed on one side of the circumference of the shell 101, the third hinge seat 133 formed on one side of the circumference of the first cover 102, and the first hinge shaft 153. The first hinge shaft 153 is inserted into the first hinge hole 118 and the second hinge hole 121 in a manner that the first hinge hole 118 and the second hinge hole 121 are coaxial. Since the axis center of the first hinge hole 118 is higher than the first end surface 114 of the first end portion 106 along the first direction, when the first hinge shaft 153 is inserted into the first hinge hole 118 and the second hinge hole 121, the axis center of the first hinge shaft 153 is higher than the first end surface 114 of the first end portion 106 along the first direction.

[0087] After the housing 101 and the first cover 102 are connected to each other through the first hinge 119 , the first cover 102 is rotatably closed or opened relative to the housing 101 .

[0088] continue Fig.13 , Fig.14 as well as Figure 2 , Figure 3 As described above, the locking portion 103 is locked and released in a manner that the housing 101 and the first cover 102 overlap each other. In the released state, the housing 101 and the first cover 102 can be opened from each other. The locking portion 103 is formed on the other side of the circumference of the storage box and is opposite to the first hinge portion 119 in the radial direction of the storage box. The locking portion 103 locks the housing 101 and the first cover 102 by, for example, a snap-fit ​​structure. The locking portion 103 includes: the second hinge seat 120 formed on the housing 101, the first stop seat 135 formed on the first cover 102, a handle 154, and a second stop seat 155. One end of the handle 154 is rotatably mounted to the second hinge seat 120, and the other end is formed with a gripping portion 156. One end of the second stop seat 155 is rotatably mounted to the middle portion 157 of the handle 154, and the other end is formed with a claw 158 that can be stopped at the first stop seat 135. In addition, as described above, the first locking seat 135 has a locking surface 138 that is higher than the axis of the first hinge shaft 153 along the first direction. When the locking portion 103 locks the shell 101 and the first cover body 102, the claw 158 of the second locking seat 155 is locked on the locking surface 138 by pressing toward the shell 101 along the first direction.

[0089] The handle 154 is used to lock or open the housing 101 and the first cover 102. The handle 154 has a main body (also referred to as a "first main body 159" for ease of distinction) and sidewalls 160 formed on both sides of the first main body 159. The first main body 159 is formed into an arc shape with the middle arched outwards compared to the two ends. The two sidewalls 160 extend from the upper end to the lower end on both sides of the first main body 159. The two sidewalls 160 protrude inwards relative to the first main body 159.

[0090] A second hinge shaft 161 is formed at the upper end of the first main body 159, and the two axial ends of the second hinge shaft 161 are respectively mounted on the two side wall parts 160. The second hinge shaft 161 is clamped into the second hinge hole 121 via the first connection groove 122 formed in the second hinge seat 120. That is, at the installation position of one end of the handle 154 and the second hinge seat 120, one end of the handle 154 crosses the first connection groove 122 in a squeezed manner through the second hinge shaft 161 and is clamped into the second hinge hole 121. In this way, the handle 154 is rotatably mounted to the housing 101.

[0091] The lower end of the first main body 159 is formed with a recessed portion 162 that is recessed toward the upper end. When the locking portion 103 locks the housing 101 and the first cover 102, the two side wall portions 160 of the handle 154 abut against the first outer side surface 113 of the peripheral wall of the housing 101. In addition, between the lower end of the first main body 159 and the first outer side surface 113 of the peripheral wall, a holding space is formed at the position of the recessed portion 162 by the two side wall portions 160, thereby forming a holding portion 156 at the lower end of the handle 154. The two side wall portions 160 are respectively formed with sixth hinge holes 163 at the position of the middle portion 157 of the handle 154, and the sixth hinge holes 163 are used for hinge connection with the second stop seat 155. The second hinge hole 121 is an open hole, that is, the two side wall portions 160 are respectively formed with second connection grooves 164, and the second connection grooves 164 open the sixth hinge hole 163 radially to the outside along the radial direction of the sixth hinge hole 163. The width of the second connection groove 164 is smaller than the inner diameter of the sixth hinge hole 163.

[0092] The second stopper 155 has a main body (also referred to as the "second main body 165" for the sake of distinction), two third arms 166 and a claw 158. The second main body 165, the two third arms 166 and the claw 158 are integrally formed. The second main body 165 is roughly plate-shaped, and the two third arms 166 are respectively arranged on both sides of the lower end of the second main body 165, and are parallel to each other. The two third arms 166 extend to the outside of the second main body 165 at an obtuse angle. The obtuse angle (also referred to as the "third angle R3" for the sake of distinction) formed between the third arm 166 and the second main body 165 is, for example, greater than 130° and less than 160°. A third hinge shaft 167 is provided at the far end of the two third arms 166 opposite to the second main body 165, and the third hinge shaft 167 is located between the two third arms 166. The third hinge shaft 167 is clamped to the sixth hinge hole 163 via the second connection grooves 164 formed in the two side wall portions 160 of the handle 154. That is, at the installation position of the second stop seat 155 and the middle portion 157 of the handle 154, one end of the second stop seat 155 crosses the second connection groove 164 in an extruded manner through the third hinge shaft 167, and is clamped into the sixth hinge hole 163. Thus, the second stop seat 155 is rotatably mounted to the handle 154. The claw 158 is provided at the upper end of the second main body portion 165, and the claw 158 is formed to extend outward from the upper end of the second main body portion 165 in a manner substantially perpendicular to the second main body portion 165 and then bend and extend downward, so that a hook portion 168 is formed at the far end.

[0093] The locking operation and releasing operation of the locking portion 103 will be described below.

[0094] [Lock Operation]

[0095] Reference Figures 15 to 17, and mainly refer to Fig.15 In the released state, the handle 154 is freely rotatably hung in the second hinge hole 121 of the second hinge seat 120 of the shell 101 through the second hinge shaft 161, and the second clamping seat 155 is freely rotatably hung in the sixth hinge hole 163 of the middle part 157 of the handle 154 through the third hinge shaft 167.

[0096] First, the first cover body 102 is rotated to a position covering the shell 101. At this time, the abutment portion 109 formed at the first end 106 of the shell 101 is partially inserted into the first receiving groove 151 of the seal 104, and the distal end of the abutment portion 109 abuts against the inclined portion 108 formed in the first receiving groove 151.

[0097] Next, the second stopper 155 is pulled so that the hook 168 of the claw 158 of the second stopper 155 passes over the second arm 137 of the first stopper 135 and hangs on the first arm 136. At this time, the installation position of the second stopper 155 and the middle portion 157 of the handle 154 (i.e., the position where the third hinge shaft 167 and the sixth hinge hole 163 are hinged to each other) is located below the side away from the housing 101 (i.e., obliquely below) compared to the installation position of one end of the handle 154 and the second hinge seat 120 (i.e., the position where the second hinge shaft 161 and the second hinge hole 121 are hinged to each other).

[0098] Main reference Fig.16 Then, the holding portion 156 of the handle 154 is pressed along the side close to the shell 101, and the handle 154 rotates toward the side of the shell 101 with the second hinge axis 161 as the rotation center. At the same time, the hook portion 168 of the claw 158 of the second stop seat 155 abuts against the stop surface 138 of the second arm portion 137, and as the installation position of the second stop seat 155 and the middle portion 157 of the handle 154 moves toward the side close to the shell 101, the hook portion 168 also continues to press the stop surface 138.

[0099] While the hook portion 168 presses the stop surface 138 toward one side of the handle 154, the abutting portion 109 continues to be inserted into the first receiving groove 151, and the two side surfaces of the abutting portion 109 (i.e., the second inner side surface 115 and the second outer side surface 116) adhere to and press the two inclined portions 108 in the first receiving groove 151. Thus, a sealing structure is formed.

[0100] Main reference Fig.17 Then, the installation position of the first stop seat 135 and the middle portion 157 of the handle 154 crosses the position along the first direction that is collinear with the installation position of one end of the handle 154 and the second hinge seat 120 (dead point position, refer to Fig.16The first cover 102 is connected to the second hinge shaft 161 and the third hinge shaft 167 in the middle of the handle 154 (a dot-dash line connecting the second hinge shaft 161 and the third hinge shaft 167), and continues to move toward the side close to the shell 101, and finally, the two side wall portions 160 of the handle 154 are attached to the shell 101. As a result, the shell 101 and the first cover body 102 are locked to each other by the locking portion 103. At this time, the installation position of the second stop seat 155 and the middle portion 157 of the handle 154 is located on a side closer to the shell 101 (inwardly obliquely downward) than the installation position of one end of the handle 154 and the second hinge seat 120. And, in this state, the reaction force from the first stop seat 135 has a component force that pulls the handle 154 toward the inner oblique upper side of the shell 101.

[0101] [Release operation]

[0102] Continue to refer to Fig.17 In the locked state, the two side wall portions 160 of the handle 154 fit the shell 101, and the installation position of the second locking seat 155 and the middle portion 157 of the handle 154 is located closer to the shell 101 than the installation position of one end of the handle 154 and the second hinge seat 120.

[0103] First, the grip portion 156 of the handle 154 is operated, and a finger or an operating wrench is clamped in the recessed portion 162 of the handle 154 .

[0104] Then, the handle 154 is pulled toward the outside of the housing 101, so that the installation position of the first stop seat 135 and the middle part 157 of the handle 154 faces the outside of the housing 101, crossing the position along the first direction that is colinear with the installation position of one end of the handle 154 and the second hinge seat 120. After crossing the dead point position, due to the reaction force from the first stop seat 135, there is a component force that pulls the handle 154 toward the outer oblique upper side of the housing 101, and the stop hook 168 of the second stop seat 155 leaves the stop surface 138 of the second arm 137. As a result, the locking of the locking part 103 is released.

[0105] The following briefly describes the installation, closing, and opening methods of the first cover 102 and the second cover 143 of the storage box.

[0106] Continue to refer to Figure 5 , Fig.11Etc., the first cover body 102 and the second cover body 143 are connected to each other through the second hinge part 142. The second hinge part 142 of the storage box for connecting the first cover body 102 and the second cover body 143 is formed on one side of the circumference of the first cover body 102. The second hinge part 142 connects the second cover body 143 and the first cover body 102 respectively, so that the second cover body 143 and the first cover body 102 can cover or open each other in a rotating manner. The second hinge part 142 includes the fourth hinge hole 141 formed above the third hinge seat 133 of the first cover body 102, the fourth hinge seat 144 formed on the second cover body 143, and the fourth hinge shaft 169. The fourth hinge shaft 169 is inserted into the fourth hinge hole 141 and the fifth hinge hole 146 in a manner that the fourth hinge hole 141 and the fifth hinge hole 146 are coaxial.

[0107] Thus, after the first cover 102 and the second cover 143 are connected to each other through the second hinge 142, the second cover 143 is rotatably closed or opened relative to the first cover 102. In the closed state, the second cover 143 covers the second storage cavity 140, and the second magnet 147 and the first magnet 145 are attracted to each other so that the second cover 143 remains in the closed state with the first cover 102.

[0108] In the storage box of the embodiment, by making the seal 104 have an inclined portion 108 inclined relative to the direction in which the shell 101 and the first cover 102 overlap each other, that is, the first direction, it is possible to reduce the influence of the slight deformation of the shell 101 and the first cover 102 when they overlap along the first direction on the seal 104, and to suppress the generation of a gap between the seal 104 and the shell 101 and the first cover 102. On the other hand, since the inclined portion 108 has a certain height relative to the gap at the overlapping position of the shell 101 and the first cover 102, it will not only extend the sealing path of the seal 104, but also increase the difficulty of the liquid crossing the height, so that the liquid in the first storage chamber 105 can be suppressed from seeping to the outside through the inclined portion 108 of the seal 104. As a result, the sealing performance of the gap between the shell 101 and the first cover 102 can be improved, and the liquid in the storage box can be more effectively suppressed from seeping to the outside.

[0109] In the storage box of the embodiment, a first storage groove 151 is formed in the sealing member 104, and two inclined portions 108 opposing each other are formed in the first storage groove 151, so that the cross-section of the first storage groove 151 gradually decreases from the opening of the first storage groove 151 toward the bottom width of the first storage groove 151, and correspondingly, the cross-section of the abutment portion 109 is formed into a roughly inverted "V" shape, so that the abutment portion 109 and the sealing member 104 can be more evenly squeezed against each other as the shell 101 and the cover body are covered with each other, thereby fitting more closely.

[0110] In addition, since the contact portion 109 is based on the first direction, when inserted into the first receiving groove 151, it is respectively attached to and pressed against the two inclined portions 108 of the seal 104 obliquely upward toward the inside and outside, even if the housing 101 and / or the first cover 102 is deformed along the first direction due to the closing, the two inclined surfaces (the second outer surface 116 and the second inner surface 115) of the contact portion 109 can maintain the attached state with the two inclined portions 108 in the first receiving groove 151. Thus, the sealing performance can be further improved.

[0111] Furthermore, by making the first angle R1 between the two side surfaces of the abutting portion 109 and the second angle R2 between the two inclined portions 108 be greater than 5° and less than 15°, the abutting portion 109 can more reliably protect the fitting state with the two inclined portions 108. When the two angles are less than 5°, the abutting portion 109 may not be able to effectively press the two inclined portions 108, and when the two angles are greater than 15°, the contact between the abutting portion 109 and the two inclined portions 108 may be affected by the deformation of the first cover 102.

[0112] In the storage box of the embodiment, by forming an installation groove 129 at the first end 106 of the shell 101 and installing the seal 104 in the installation groove 129, the deformation amount and deformation direction of the seal 104 can be limited, thereby suppressing gaps and the like caused by disordered and uncontrollable deformation of the seal 104.

[0113] Furthermore, by making the cross-section of the installation groove 129 defined by the third inner side surface 130 of the second peripheral wall 124, the second connecting portion 128 and the third outer side surface 131 of the first connecting portion 126 roughly trapezoidal, and making the outer periphery of the cross-section of the seal 104 roughly trapezoidal, the seal 104 can be deformed obliquely upward and fit into the installation groove 129 as the shell 101 and the cover body further cover each other, thereby further suppressing the generation of a gap between the seal 104 and the first cover body 102 caused by the deformation of the first cover body 102.

[0114] In the storage box of the embodiment, by making the axis of the first hinge shaft 153 (first hinge hole 118) higher than the first end face 114 of the first end portion 106 along the first direction, and the axis of the second hinge hole 121 higher than the second end face 132 of the second end portion 107 along the first direction, it is possible to achieve that when the first cover body 102 and the shell body 101 are covered with each other, the second end face 132 of the second end portion 107 and the first end face 114 of the first end portion 106 are opposed to each other with a slight gap therebetween, so that the portion of the squeezed seal 104 that escapes the mounting groove 129 can freely stretch in the gap, thereby preventing the seal 104 from abutting against the first end face 114 due to being squeezed, thereby causing wrinkles in the portion within the mounting groove 129, resulting in the formation of gaps, etc.

[0115] In the storage box of the embodiment, by making the axis of the first hinge shaft 153 (first hinge hole 118) higher than the first end face 114 of the first end portion 106 along the first direction, and in addition, the stopping surface 138 is higher than the axis of the first hinge hole 118 along the first direction, the first cover body 102 and the shell 101 can be more firmly locked to each other through the locking portion 103, thereby preventing the first cover body 102 and the shell 101 from loosening along the first direction.

[0116] In addition, by making the stop surface 138 higher than the axis of the first hinge hole 118 by more than 3 mm and less than 7 mm along the first direction, the first cover 102 and the housing 101 can be firmly locked to each other while reducing the deformation of the first cover 102, especially reducing the deformation of the first area 139 of the first cover 102. When the stop surface 138 is less than 3 mm higher than the axis of the first hinge hole 118 along the first direction, the first cover 102 and the housing 101 may be loose, resulting in the abutment 109 being unable to fully press the seal 104, thereby causing a gap between the abutment 109 and the seal 104. When the stop surface 138 is higher than the axis of the first hinge hole 118 along the first direction by more than 10 mm, the deformation of the first area 139 of the first cover 102 may be too large, thereby causing a gap between the seal 104 and the abutment 109 in the first area 139 of the first cover 102.

[0117] In the storage box of the embodiment, by making the strength of the first region 139, which is the middle region of the first cover 102 along the direction in which the third hinge seat 133 and the first stop seat 135 are opposite to each other, the deformation of the first cover 102 in the first region 139 can be suppressed. For example, when the first cover 102 and the housing 101 are connected by the first hinge portion 119 located on one side of the circumference of the storage box and locked by the locking portion 103 located on the other side of the circumference of the storage box, the first cover 102 as a whole tends to be bent, and the force applied to the portion in the first region 139 is the largest. Therefore, by making the strength of the first region 139 greater than the strength of the other regions, the deformation of the first cover 102 in the first region 139 can be suppressed, and the deformation of the sealing member 104 due to the deformation of the first region 139 can be suppressed. Thus, the gap between the abutting portion 109 and the sealing member 104 in the first region 139 can be suppressed, and the sealing performance of the storage box in the first region 139 can be further improved.

[0118] In the storage box of the embodiment, when the housing 101 and the first cover 102 are locked to each other by the locking portion 103, the installation position of the second stop seat 155 and the middle portion 157 of the handle 154 is closer to the side of the housing 101 than the installation position of one end of the handle 154 and the second hinge seat 120, so that the housing 101 and the first cover 102 can be locked more reliably, and the housing 101 and the first cover 102 can be prevented from being loosened in the event of a fall, collision, or other accident. For example, when the housing 101 and the first cover 102 are locked to each other by the locking portion 103, due to the reaction force from the first stop seat 135, there is a component force that pulls the handle 154 obliquely upward toward the inside of the housing 101, and through this component force, it can be achieved that when there is no external force acting on the handle 154, the locking portion 103 as a whole maintains a self-locking state, thereby preventing the locking portion 103 from being accidentally loosened.

[0119] In addition, when locking, the hook portion 168 of the claw 158 of the second locking seat 155 crosses the first arm portion 136 and abuts against the locking surface 138 of the second arm portion 137. The first arm portion 136 can limit the sliding of the hook portion 168 relative to the second arm portion 137, and it can further be achieved that when there is no external force acting on the handle 154, the locking portion 103 as a whole remains in a self-locking state, thereby preventing the locking portion 103 from being accidentally released.

[0120] In addition, refer to Figure 3In other embodiments, the storage box may further include a water filter frame 170, which is detachably stored in the first storage cavity 105. The water filter frame 170 may include a handle 171, and when the first cover 102 and the housing 101 are covered, the handle 171 of the water filter frame 170 extends into the avoidance portion 127 formed on one side of the second bottom wall 123.

[0121] The water filter rack 170 can more easily remove personal items soaked in the first storage chamber 105. In addition, the second storage chamber 140 is formed in the first cover 102, so that personal items taken out of the first storage chamber 105 or other personal items that do not need to be soaked can be conveniently stored.

[0122] Reference Fig.18 In the above embodiment, the seal 104 is provided at the second end 107 of the first cover 102, and the abutment portion 109 is formed at the first end 106 of the housing 101, but the present invention is not limited thereto. Alternatively, the abutment portion 109 may be formed at the second end 107 of the first cover 102, and the seal 104 may be provided at the first end 106 of the housing 101.

[0123] Reference Fig.19 Alternatively, in order to further improve the sealing performance, the sealing member 104 may be formed with a plurality of first receiving grooves 151 along the width direction, and correspondingly, abutment portions 109 may be formed at a plurality of locations on the other of the first end portion 106 and the second end portion 107, and when the shell 101 and the first cover body 102 are covered with each other, each abutment portion 109 is respectively inserted into the corresponding first receiving groove 151.

[0124] It should be noted that a mounting groove 129 may be formed in the second end portion 107, in which a seal 104 having a plurality of first receiving grooves 151 formed along the width direction may be installed; or a plurality of mounting grooves 129 (for example, two) may be formed in the second end portion 107, in which each mounting groove 129 may be respectively installed a seal 104 having a first receiving groove 151 formed therein.

[0125] In addition, when the seal 104 is formed with multiple installation grooves 129 and the abutment portions 109 are formed at multiple locations, the seals 104 may be all installed at the second end 107 and the abutment portions 109 may be all formed at the first end 106; the seals 104 may be all installed at the first end 106 and the abutment portions 109 may be all formed at the second end 107; or some of the seals 104 may be installed at the first end 106 and other parts of the seals 104 may be installed at the second end 107, and some of the abutment portions 109 may be formed at the first end 106 and other parts of the abutment portions 109 may be formed at the second end 107.

[0126] Reference Fig. 20 In the above embodiment, an example is described in which the first receiving groove 151 is formed in the seal 104, and the abutment portion 109 is formed at the second end 107 correspondingly, but it is not limited to this. The seal 104 may also be provided at one of the first end 106 and the second end 107, and the seal 104 may be formed with a protrusion 172 protruding toward the other of the first end 106 and the second end 107 across the entire length. The inclined portion 108 is formed on the side of the protrusion 172. A second receiving groove 173 is formed across the entire circumference at the other of the first end 106 and the second end 107, and the abutment portion 109 is formed in the second receiving groove 173. When the housing 101 and the first cover 102 are locked by the locking portion 103 and cover each other, the protrusion 172 is inserted into the second receiving groove 173, and the inclined portion 108 abuts against the abutment portion 109. In this manner, the protrusion 172 can be formed in a substantially inverted "V" shape, and two inclined portions 108 are respectively formed on both sides of the protrusion 172. Correspondingly, the second receiving groove 173 is also substantially formed in an inverted "V" shape, and the abutment portions 109 are respectively formed in the second receiving groove 173. Thus, when the housing 101 and the first cover 102 are covered with each other, the two inclined portions 108 abut against the two abutment portions 109 respectively.

[0127] Similarly, the seal 104 may be formed at the first end 106 , and correspondingly, the second receiving groove 173 may be formed at the second end 107 ; or the seal 104 may be formed at the second end 107 , and correspondingly, the second receiving groove 173 may be formed at the first end 106 .

[0128] Continue to refer to Fig. 20 In addition, in order to improve the rigidity of the protrusion 172 of the seal 104, one of the seals 104 may be provided at the first end 106 and the second end 107, and a rib 174 protruding toward the other of the first end 106 and the second end 107 may be formed across the entire circumference; and at least the protrusion 172 of the seal 104 wraps at least a portion of the rib 174. For example, the rib 174 is formed at the first end 106, and the cross section of the rib 174 may be substantially in an inverted "V" shape, and correspondingly, the protrusion 172 of the seal 104 is formed by wrapping the rib 174, so that when the protrusion 172 is inserted into the second receiving groove 173 formed at the second end 107, the protrusion 172 can be suppressed from deforming in a bending manner in the second receiving groove 173, and the abutting portion 109 and the seal 104 can be pressed against each other more evenly as the housing 101 and the cover body are covered with each other, so as to fit more closely.

[0129] Reference Fig.21In the storage box of the embodiment, an example is described in which the seal 104 is formed with multiple inclined portions 108 in opposite locations, but the invention is not limited thereto. The seal 104 may also be formed with only one inclined portion 108. For example, a first inclined surface 175 may be formed across the entire circumference at the second end 107 of the first cover 102, and the seal 104 may be formed at the position of the inclined surface. Correspondingly, a second inclined surface 176 is formed at the position of the first end 106 of the shell 101 connected to the first storage cavity 105 as the abutment portion 109. When the first cover 102 and the shell 101 are covered with each other, the seal 104 formed on the first inclined surface 175 abuts against the second inclined surface 176 as the abutment portion 109.

[0130] Reference Fig. 22 In the storage box of the embodiment, an example in which the housing 101 and the first cover 102 are connected to each other through the first hinge 119 is described, but the present invention is not limited thereto. For example, the storage box may not have the first hinge 119, but may include a plurality of locking portions 103, which are spaced apart along the circumference of the storage box. By locking all the locking portions 103, the housing 101 and the first cover 102 are locked. In addition, by releasing all the locking portions 103, the first cover 102 can be opened relative to the housing 101.

[0131] In the storage box of the embodiment, an example is described in which the second storage cavity 140 is formed in the first cover 102, but the present invention is not limited thereto. The second cover 143 may not form the second storage cavity 140, but may only have the function of a cover. In this case, the storage box may not have the second cover 143.

[0132] In the storage box of the embodiment, the locking portion 103 is described as an example of a buckle structure, but it is not limited to this. The locking portion 103 can be any locking structure as long as it can reliably lock the first cover 102 and the housing 101 and can be released. For example, it can be a rotation clamping structure, a thread locking structure, and other locking structures.

[0133] The first storage cavity 105 of the storage box of the embodiment can be used to contain liquids such as purified water and disinfectant, and to store and soak personal items with high requirements for hygiene such as dentures, toothbrushes, spoons, chopsticks, razors, etc.

[0134] Although examples of the present embodiment have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present embodiment, and the scope of the present embodiment is defined by the claims and their equivalents.
