In the present embodiment, the two positioning columns 1127 and the two positioning walls 1128 of the first casing 112 can help to position the assembling seat 12 during the process of assembling the assembling seat 12 to the first casing 112. It should be noted that the two positioning columns 1127 and the two positioning walls 1128 of the first housing 112 are optional structures. In other embodiments, the first housing 112 may be free of two positioning posts 1127 and two positioning walls 1128. The assembly seat 12 is not limited to being fixed to the first casing 112 by screws 80.

In this embodiment, the first casing 112 may further have a notch 1129, and the second casing 113 also has a notch 1131. The notch 1129 of the first casing 112 and the notch 1131 of the second casing 113 together form a through hole 116, and the through hole 116 is communicated with the accommodating space 115. The vacuum storage box 1 may further include a guide 90. The guiding element 90 is, for example, an annular body, and the guiding element 90 is fixed to the through hole 116. In detail, the guiding element 90 has an abutting flange 91, a first abutting projection 92 and a second abutting projection 93. The first abutting projection 92 and the second abutting projection 93 are kept apart from the abutting flange 91 in the axial direction of the guide 90.

In the present embodiment, the extension 42 of the button 40 has a slope 421 and a flat 422 connected to each other. The inclined guiding surface 421 is located at an end of the extending portion 42 opposite to the operating portion 41, the plane 422 and the inclined guiding surface 421 form an acute angle and are parallel to the second surface 1123, and the inclined guiding surface 421 and the plane 422 together form a pushing tip 423. In the present embodiment, the button 40 is movable between a first position (shown in fig. 4) and a second position (shown in fig. 5). When the button 40 is at the first position, the pushing tip 423 of the button 40 is separated from the second wide section 32 of the flexible sealing member 30, and the compression part 321 of the flexible sealing member 30 seals the through hole 1124, so that the storage space 114 is not connected to the accommodating space 115. The second position of the button 40 will be described in detail later.

The first elastic member 50 is a torsion spring. The first elastic member 50 includes a coil 51, a first elastic arm 52 and a second elastic arm 53 connected to each other. The end of the first resilient arm 52 remote from the coil 51 is fixed to the assembly seat 12, while the end of the second resilient arm 53 remote from the coil 51 presses against the flexible seal 30.

The end of second spring arm 53 remote from spring coil 51 has a coil portion 531, and coil portion 531 is helical and presses against the side of pressure receiving portion 321 of flexible seal 30 remote from through hole 1124. The outer diameter of the coil portion 531 gradually decreases from the side where the coil portion 531 abuts against the pressure receiving portion 321 toward the side away from the pressure receiving portion 321. In this embodiment. The spring constant of first spring 50 is, for example, greater than the spring constant of flexible seal 30.

In this embodiment, the first housing member 112 also has a positioning wall 1130. The positioning wall 1130 is adjacent to the positioning wall 1128. The coil 51 of the first elastic member 50 abuts against the positioning wall 1130, and the first elastic arm 52 of the first elastic member 50 is positioned by the positioning wall 1130 and the positioning wall 1128. It should be noted that the retaining wall 1130 is an optional structure. In other embodiments, the first housing member 112 may be devoid of the retaining wall 1130.

In this embodiment, the vacuum storage case 1 may further include a second elastic member 100. The second elastic member 100 is, for example, an extension spring. One end of the second elastic member 100 is fixed to the assembly seat 12, and the other end of the second elastic member 100 is fixed to the button 40. In detail, the assembly seat 12 further has a fixing post 124, and the extension portion 42 of the button 40 also has a fixing post 424. Opposite ends of the second elastic element 100 are fixed to the fixing

posts

124 and 424, respectively. The second elastic member 100 is used for applying a force to move the button 40 from the second position toward the first position.

In this embodiment, the vacuum storage box 1 may further include a control circuit board 110 and a power switch 120. The control circuit board 110 is located in the accommodating space 115, the power switch 120 is disposed on the first casing 112, and the power switch 120 and the air extractor 20 are electrically connected to the control circuit board 110 through an electric wire (not shown), for example.

In this embodiment, the second casing 113 has an outer surface 1132 and a battery jar 1133. The vacuum storage case 1 may further include a battery cover 130. The outer surface 1132 faces away from the receiving space 115, and the battery case 1133 is recessed from the outer surface 1132. The battery case 1133 is used to accommodate a plurality of batteries 2. A conductive member 140 electrically connected to the control circuit board 110 is disposed in the battery jar 1133, and the battery 2 is electrically connected to the control circuit board 110 through the conductive member 140 after being installed in the battery jar 1133. The battery 2 is used to provide the power required for the operation of the vacuum storage case 1. The battery cover 130 is mounted on the second housing 113 and covers the battery groove 1133.

In the present embodiment, the vacuum storage box 1 may further include a protective member 150. The protection member 150 is made of, for example, silicon rubber or rubber, the hardness of the protection member 150 is less than that of the housing 10, and the protection member 150 is sleeved on the second housing 113 and shields the battery cover 130. The protection member 150 can provide a buffer and scratch-resistant protection effect for the second casing member 113. It should be noted that the protector 150 is an optional component. In other embodiments, the vacuum storage box 1 may omit the protector 150.

After the power switch 120 is activated, the control circuit board 110 causes the air extractor 20 to start to extract air from the storage space 114 through the connecting tube 70 and the air extracting hole 1125, so that the storage space 114 is in a vacuum state (i.e., a negative pressure state). In this way, the articles stored in the storage space 114 can be prevented from contacting with air, so as to ensure the quality of the articles.

In addition, since one end of the first elastic arm 52 of the first elastic member 50 presses the pressed portion 321 of the flexible sealing member 30 away from the through hole 1124, the sealing performance of the pressed portion 321 of the flexible sealing member 30 against the through hole 1124 can be enhanced under the condition that the button 40 is separated from the flexible sealing member 30, so that the storage space 114 is not communicated with the outside, and the storage space 114 is ensured to be in a vacuum state, thereby properly storing the article.

Furthermore, since the coil portion 531 is of a spiral structure and the outer diameter of the coil portion 531 is gradually decreased from the side where the coil portion 531 presses against the pressed portion 321 toward the side away from the pressed portion 321, the contact area between the coil portion 531 and the pressed portion 321 of the flexible seal 30 can be increased, so that the coil portion 531 firmly presses against the pressed portion 321 of the flexible seal 30, and the sealing performance of the pressed portion 321 of the flexible seal 30 against the through hole 1124 can be further enhanced.

When the storage space 114 is in a vacuum state (negative pressure state), the cover 111 is tightly abutted against the sealing cushion 60, and it is not easy to separate the cover 111 from the first casing member 112 to take out the article. At this time, the user may press the operating portion 41 of the button 40 to move the button 40 from the first position to the second position against the elastic force of the second elastic member 100. Referring to fig. 5, fig. 5 is a schematic cross-sectional view of the button 40 of fig. 4 in a second position.

When the button 40 moves from the first position to the second position, the pushing tip 423 of the extending portion 42 of the button 40 overcomes the elastic force of the first elastic member 50 to lift and deform the pressed portion 321 of the flexible sealing member 30, so that the through hole 1124 is opened. In this way, the storage space 114 can be communicated with the accommodating space 115 through the through hole 1124, and air can enter the storage space 114 from the through hole 1124 to release the vacuum state of the storage space 114, so that the cover 111 can be easily separated from the first casing 112, and a user can take out articles.

After releasing the button 40, the second elastic member 100 drives the button 40 to return from the second position to the first position, and since the pushing tip 423 is separated from the compression portion 321 of the flexible sealing member 30 when the button 40 is at the first position, the first elastic member 50 makes the compression portion 321 of the flexible sealing member 30 close the through hole 1124.

As shown in table 1 below, table 1 summarizes the number of times that the first elastic member 50 allows the button 40 to successfully open the through hole 1124 in 30 actual tests and the number of times that the first elastic member 50 allows the flexible seal member 30 to close the through hole 1124 in each sealing time interval in another 30 actual tests under different wire diameters of the first elastic member 50.

From the above table, the first elastic member 50 with a wire diameter of 0.3mm allows the button 40 to successfully open the through hole 1124 of the flexible sealing member 30 every 30 practical tests, but half of the practical tests of the first elastic member 50 with a wire diameter of 0.3mm will not allow the flexible sealing member 30 to close the through hole 1124 for more than 2 hours in another 30 practical tests. The first elastic member 50 with a wire diameter of 0.5mm allows the button 40 to successfully open the through hole 1124 of the flexible sealing member 30 in each of 30 practical tests, and the first elastic member 50 with a wire diameter of 0.5mm allows the flexible sealing member 30 to close the through hole 1124 in more than 2 hours in each of 30 practical tests. First elastic member 50 with a wire diameter of 0.8mm allows button 40 to successfully open through-hole 1124 only 23 times in 30 tests, while first elastic member 50 with a wire diameter of 0.8mm allows flexible seal 30 to close through-hole 1124 for more than 2 hours each time in 30 tests. The first elastic member 50 with a diameter of 1mm allows the button 40 to successfully open the through hole 1124 only 11 times in 30 actual tests, and the first elastic member 50 with a diameter of 1mm allows the flexible sealing member 30 to close the through hole 1124 for more than 2 hours each time in 30 additional tests.

It can be seen that the wire diameter (elastic modulus) of the first elastic member 50 cannot be too large, otherwise it is difficult for the pressing tip 423 of the button 40 to make the pressure receiving portion 321 of the flexible sealing member 30 open the through hole 1124 when the button 40 is pressed. On the other hand, the wire diameter (elastic coefficient) of the first elastic element 50 cannot be too small, otherwise the elasticity of the first elastic element 50 is offset by the elasticity of the flexible sealing element 30 because the flexible sealing element 30 is made of soft material such as silicon rubber or rubber, and the flexible sealing element 30 cannot be assisted to close the through hole 1124. Therefore, in the above practical test, first elastic member 50 with a wire diameter of 0.5mm can ensure that flexible sealing member 30 can successfully open through hole 1124 each time button 40 is pressed, and at the same time, has enough elasticity to allow flexible sealing member 30 to close through hole 1124.

It should be noted that the wire diameter of the first elastic member 50 is not limited to 0.5 mm. Since the elastic coefficient of the first elastic element 50 is not only the wire diameter but also the material of the first elastic element 50, the wire diameter and the material of the first elastic element 50 can be selected according to the actual requirement, so as to achieve the effect that the button 40 can successfully open the through hole 1124 of the flexible sealing element 30 and have enough elasticity to seal the through hole 1124 of the flexible sealing element 30.

It should be noted that the structure for deforming the pressed portion 321 of the flexible sealing member 30 of the button 40 is not limited to the tip structure. The tip configuration can be adjusted to any suitable configuration so long as it allows the compression portion 321 of flexible seal 30 to deform when button 40 is moved to the second position.

Next, referring to fig. 6 to 7, fig. 6 is a partial perspective view of a vacuum storage box according to a second embodiment of the present invention. Fig. 7 is an exploded view of fig. 6.

The vacuum storage box 1a of the present embodiment is similar to the vacuum storage box 1 described above with reference to fig. 1 to 5, and the difference between the two is mainly the form of the first elastic member, so the following description is only directed to the first elastic member 50a of the vacuum storage box 1a of the present embodiment, and fig. 6 and 7 only show a part of the vacuum storage box 1a, and the same parts between the two are not repeated and drawn again.

In the present embodiment, the first elastic element 50a is a spring, and the first elastic element 50a includes a bending arm 51a, a first elastic arm 52a and a second elastic arm 53 a. The first elastic arm 52a is connected to one side of the bending arm 51a, and the second elastic arm 53a is connected to the other side of the bending arm 51 a. The first elastic arm 52a is fixed to the assembly seat 12 of the housing 10. The end of the second spring arm 53a away from the bending arm 51a has an arc convex surface 531a, and the arc convex surface 531a presses against the side of the pressed portion 321 of the flexible sealing member 30 away from the through hole 1124.

As shown in table 2 below, table 2 summarizes the number of times that the first elastic member 50a allows the button 40 to successfully open the through hole 1124 in 30 practical tests and the number of times that the first elastic member 50a allows the flexible seal member 30 to close the through hole 1124 in each sealing time interval in another 30 practical tests under different thickness conditions of the first elastic member 50 a.

From the above table, the first elastic member 50a with a thickness of 0.1mm allows the button 40 to successfully open the through hole 1124 of the flexible sealing member 30 every 30 practical tests, but the first elastic member 50a has more than half of the time that the flexible sealing member 30 cannot close the through hole 1124 in more than 2 hours in another 30 practical tests. The first elastic member 50a with a thickness of 0.15mm allows the button 40 to successfully open the through hole 1124 of the flexible sealing member 30 in each of 30 actual tests, and allows the flexible sealing member 30 to close the through hole 1124 in more than 2 hours in each of 30 additional actual tests of the first elastic member 50 a. First elastic member 50a, having a thickness of 0.2mm, allows only 26 of 30 actual tests of button 40 to successfully open flexible seal 30 through hole 1124, while first elastic member 50a allows flexible seal 30 to close through hole 1124 for more than 2 hours each time in 30 additional actual tests.

It can be seen that the thickness (elastic modulus) of the first elastic member 50a cannot be too large, otherwise it is difficult for the pressing tip 423 of the button 40 to make the pressure receiving portion 321 of the flexible sealing member 30 open the through hole 1124 when the button 40 is pressed. On the other hand, the thickness (elastic coefficient) of the first elastic element 50a cannot be too small, otherwise the elasticity of the first elastic element 50a is offset by the elasticity of the flexible sealing element 30 because the flexible sealing element 30 is made of soft material such as silicon rubber or rubber, and thus the flexible sealing element 30 cannot be assisted to close the through hole 1124. Thus, in the above practical test, first resilient member 50a having a thickness of 0.15mm ensures that each push of button 40 successfully opens flexible seal 30 into through-hole 1124, while having sufficient resiliency to allow flexible seal 30 to close through-hole 1124.

It should be noted that the thickness of the first elastic member 50a is not limited to 0.15 mm. Since the elastic coefficient of the first elastic element 50a is not only the thickness, but also the material is one of the factors influencing the elastic coefficient of the first elastic element 50a, the thickness and the material suitable for the first elastic element 50a can be selected according to the actual requirement, so as to achieve the effect that the button 40 can successfully enable the flexible sealing element 30 to successfully open the through hole 1124, and at the same time, the flexible sealing element 30 has enough elasticity to seal the through hole 1124.

Next, referring to fig. 8 to 9, fig. 8 is a partial perspective view of a vacuum storage box according to a third embodiment of the present invention. Fig. 9 is a partial perspective view of fig. 8 from another perspective.

The vacuum storage box of the present embodiment is similar to the vacuum storage box 1 described above with reference to fig. 1 to 5, and the difference between the two is mainly that the form of the first elastic member is different, so that only the first elastic member 50b of the vacuum storage box of the present embodiment is described in detail below, and fig. 8 and 9 only show the assembly seat 12, the first elastic member 50b and the button 40, and the same portions between the vacuum storage box of the present embodiment and the vacuum storage box 1 described above with reference to fig. 1 to 5 are not described and depicted again.

In this embodiment, the first elastic element 50b is a spring, and the first elastic element 50b is fixed to the button 40 and can slide with the button 40 relative to the assembly seat 12. The first elastic element 50b has a bending tip 51b, and the bending tip 51b is used for pressing the pressed portion of the flexible sealing element (e.g. pressed portion 321 of flexible sealing element 30 shown in fig. 4) away from the side of the through hole (e.g. through hole 1124 shown in fig. 4) when the button 40 is at the first position, so as to help the flexible sealing element to close the through hole. On the other hand, the bending tip 51b is used to separate from the pressed portion of the flexible seal when the button 40 is at the second position, so as to avoid the bending tip 51b from interfering with the process of the button 40 forcing the flexible seal to open the through hole.

It should be noted that the first elastic member 50b is not limited to being fixed to the button 40. In other embodiments, the first elastic member may be fixed to the assembly seat. Under the configuration, when the button is at the first position, the bending tip of the first elastic element can still press the pressed part of the flexible sealing element; when the button is in the second position, the button forces the flexible sealing member to open the through hole and simultaneously lifts and deforms the first elastic member.

According to the vacuum storage box of the above embodiment, since the first elastic member is configured to press the flexible sealing member covering the through hole, the sealing performance of the flexible sealing member with respect to the through hole is enhanced when the button does not push the flexible sealing member, so that the storage space is not connected to the outside, thereby ensuring that the storage space is in a vacuum state, and the through hole is opened when the button pushes the flexible sealing member, thereby releasing the storage space from the vacuum state, thereby ensuring that the vacuum storage box can effectively provide a vacuum effect to properly store the articles, and allowing a user to easily open the vacuum storage box when the user needs to take out the articles from the vacuum storage box.

Furthermore, because the winding portion is in a spiral structure and the outer diameter of the winding portion is gradually reduced from the side of the winding portion, which is pressed against the pressed portion, to the side away from the pressed portion, the contact area between the winding portion and the pressed portion of the flexible sealing member can be increased, so that the winding portion can firmly press against the pressed portion of the flexible sealing member, and the sealing performance of the pressed portion of the flexible sealing member to the through hole is further enhanced.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the utility model. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
