The exhaust device 20 and the connecting pipe 70 are located in the accommodating space 115, and the exhaust device 20 is connected to the other end of the exhaust hole 1125 of the first shell 112 through the connecting pipe 70. The exhaust device 20 is used to exhaust the air in the storage space 114 to the accommodating space 115 through the connecting pipe 70 and the exhaust hole 1125, so that the storage space 114 is in a vacuum state.

[0046] It should be noted that the connection pipe 70 is not intended to limit the present invention. In other embodiments, the vacuum storage box 1 may omit the connection pipe 70 , and the air extraction device 20 may be directly connected to the air extraction hole 1125 .

[0047] In the present embodiment, the first shell 112 further has an assembly hole 1126. The assembly hole 1126 connects the storage space 114 and the accommodating space 115. The flexible seal 30 is made of a soft material such as rubber or silicone. The flexible seal 30 includes a first wide diameter section 31, a second wide diameter section 32 and a narrow diameter section 33. The opposite ends of the narrow diameter section 33 are respectively connected to the first wide diameter section 31 and the second wide diameter section 32, and the width of the narrow diameter section 33 is smaller than the width of the first wide diameter section 31 and the width of the second wide diameter section 32. The first wide diameter section 31 of the flexible seal 30 is located in the storage space 114 and abuts against the first surface 1122 of the first shell 112, the second wide diameter section 32 of the flexible seal 30 is located in the accommodating space 115 and abuts against the second surface 1123 of the first shell 112, and the narrow diameter section 33 of the flexible seal 30 is located in the assembly hole 1126. The thickness of the second wide diameter section 32 of the flexible sealing member 30 gradually decreases from the center to the outer edge thereof. The second wide diameter section 32 of the flexible sealing member 30 has a pressure receiving portion 321 , and the pressure receiving portion 321 covers the through hole 1124 of the first shell member 112 .

[0048] In the present embodiment, the first shell 112 further has two positioning posts 1127 and two positioning walls 1128, the two positioning posts 1127 and the two positioning walls 1128 protrude from the second surface 1123 of the first shell 112, and the two positioning posts 1127 are located between the two positioning walls 1128. The housing 10 further includes an assembly seat 12. The assembly seat 12 has two positioning holes 121 and two through holes 122, and the two through holes 122 are respectively connected to the two positioning holes 121. The assembly seat 12 is located in the accommodating space 115 and is superimposed on the second surface 1123 of the first shell 112, and the assembly seat 12 is against the two positioning walls 1128, and the two positioning posts 1127 of the first shell 112 are respectively located in the two positioning holes 121 of the assembly portion. The vacuum storage box 1 may further include two screws 80 . The two screws 80 are respectively passed through the two through holes 122 and locked in the two positioning posts 1127 to fix the assembly seat 12 to the first shell 112 .

[0049] In the present embodiment, the two positioning posts 1127 and the two positioning walls 1128 of the first shell 112 can help position the assembly seat 12 during the process of assembling the assembly seat 12 to the first shell 112. It should be noted that the two positioning posts 1127 and the two positioning walls 1128 of the first shell 112 are optional structures. In other embodiments, the first shell 112 may not have the two positioning posts 1127 and the two positioning walls 1128. In addition, the assembly seat 12 is not limited to being fixed to the first shell 112 by the screws 80. In other embodiments, the assembly seat 12 can be fixed to the first shell 112 by other suitable methods (such as clamping or bonding).

[0050] In this embodiment, the first shell 112 may also have a notch 1129, and the second shell 113 may also have a notch 1131. The notch 1129 of the first shell 112 and the notch 1131 of the second shell 113 together form a through hole 116, and the through hole 116 is connected to the accommodating space 115. The vacuum storage box 1 may also include a guide member 90. The guide member 90 is, for example, an annular body, and the guide member 90 is fixed to the through hole 116. In detail, the guide member 90 has a stop flange 91, a first stop protrusion 92, and a second stop protrusion 93. The first stop protrusion 92 and the second stop protrusion 93 are spaced apart from the stop flange 91 in the axial direction of the guide member 90. A portion of the first shell 112 is located between the abutting flange 91 and the first abutting protrusion 92 , and a portion of the second shell 113 is located between the abutting flange 91 and the second abutting protrusion 93 , so that the guide member 90 is fixed to the through hole 116 .

[0051] The guide member 90 has a guide hole 94, and the assembly seat 12 has a guide groove 123. The guide hole 94 of the guide member 90 is aligned with the guide groove 123 of the assembly seat 12. The button 40 includes an operating portion 41 and an extension portion 42. The operating portion 41 is slidably located in the guide hole 94 of the guide member 90, and the extension portion 42 is slidably located in the guide groove 123 of the assembly seat 12. The guide hole 94 of the guide member 90 and the guide groove 123 of the assembly seat 12 can help the button 40 slide smoothly.

[0052] In this embodiment, the extension portion 42 of the button 40 has a guide slope 421 and a plane 422 connected to each other. The guide slope 421 is located at one end of the extension portion 42 relative to the operating portion 41, the plane 422 and the guide slope 421 form an acute angle and are parallel to the second surface 1123, and the guide slope 421 and the plane 422 together form a push tip 423. In this embodiment, the button 40 can be in the first position (such as Figure 4 ) and the second position (as shown Figure 5 When the button 40 is in the first position, the push tip 423 of the button 40 is separated from the second wide diameter section 32 of the flexible seal 30, and the pressure receiving portion 321 of the flexible seal 30 closes the through hole 1124, so that the storage space 114 is not connected to the accommodating space 115 and is not connected to the outside. The second position of the button 40 will be described in detail later.

[0053] The first elastic member 50 is a torsion spring. The first elastic member 50 includes a spring coil 51, a first elastic arm 52 and a second elastic arm 53 connected to each other. One end of the first elastic arm 52 away from the spring coil 51 is fixed to the assembly seat 12, and one end of the second elastic arm 53 away from the spring coil 51 presses against the flexible seal 30. In detail, one end of the first elastic arm 52 away from the spring coil 51 is fixed to the assembly seat 12 through a screw 80. One end of the second elastic arm 53 away from the spring coil 51 has a coil portion 531, and the coil portion 531 is a spiral structure and presses against the side of the pressure-bearing portion 321 of the flexible seal 30 away from the through hole 1124. The outer diameter of the coil portion 531 gradually decreases from the side of the coil portion 531 pressing against the pressure-bearing portion 321 to the side away from the pressure-bearing portion 321. In this embodiment. The elastic coefficient of the first elastic member 50 is, for example, greater than the elastic coefficient of the flexible seal 30.

[0054] In this embodiment, the first shell 112 further has a positioning wall 1130. The positioning wall 1130 is adjacent to the positioning wall 1128. The spring 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 positioning wall 1130 is an optional structure. In other embodiments, the first shell 112 may not have the positioning wall 1130.

[0055] In this embodiment, the vacuum storage box 1 may further include a second elastic member 100. The second elastic member 100 is, for example, a tension 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 also has a fixing column 124, and the extension portion 42 of the button 40 also has a fixing column 424. The opposite ends of the second elastic member 100 are respectively fixed to the fixing column 124 and the fixing column 424. The second elastic member 100 is used to apply a force to the button 40 to move from the second position to the first position.

[0056] 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 in the first shell 112, and the power switch 120 and the vacuum device 20 are electrically connected to the control circuit board 110, for example, through wires (not shown).

[0057] In this embodiment, the second shell 113 has an outer surface 1132 and a battery slot 1133. The vacuum storage box 1 may further include a battery cover 130. The outer surface 1132 faces away from the accommodating space 115, and the battery slot 1133 is formed by being recessed from the outer surface 1132. The battery slot 1133 is used to accommodate a plurality of batteries 2. A conductive member 140 electrically connected to the control circuit board 110 is provided in the battery slot 1133. After the battery 2 is installed in the battery slot 1133, it is electrically connected to the control circuit board 110 through the conductive member 140. The battery 2 is used to provide the power required for the operation of the vacuum storage box 1. The battery cover 130 is installed on the second shell 113 and covers the battery slot 1133.

[0058] In this embodiment, the vacuum storage box 1 may further include a protective member 150. The material of the protective member 150 is, for example, silicone or rubber. The hardness of the protective member 150 is less than the hardness of the housing 10, and the protective member 150 is sleeved on the second housing 113 and shields the battery cover 130. The protective member 150 can provide a buffering and scratch-proof protective effect for the second housing 113. It should be noted that the protective member 150 is an optional component. In other embodiments, the vacuum storage box 1 may omit the protective member 150.

[0059] After the power switch 120 is triggered, the control circuit board 110 will cause the air extraction device 20 to start extracting the air in the storage space 114 through the connecting pipe 70 and the air extraction hole 1125, so that the storage space 114 is in a vacuum state (i.e., a negative pressure state). In this way, the items stored in the storage space 114 can be prevented from contacting with the air, thereby ensuring the quality of the items.

[0060] In addition, since one end of the first elastic arm 52 of the first elastic member 50 presses against the side of the pressure-bearing portion 321 of the flexible seal 30 away from the through hole 1124, the sealing performance of the pressure-bearing portion 321 of the flexible seal 30 with respect to the through hole 1124 can be strengthened when the button 40 is separated from the flexible seal 30, so that the storage space 114 is not connected to the outside, thereby ensuring that the storage space 114 is in a vacuum state to properly preserve the items.

[0061] Furthermore, since the coil portion 531 is a spiral structure and the outer diameter of the coil portion 531 is gradually reduced from the side where the coil portion 531 presses against the pressure-bearing portion 321 toward the side away from the pressure-bearing portion 321, the contact area between the coil portion 531 and the pressure-bearing portion 321 of the flexible seal 30 can be increased, so that the coil portion 531 can be firmly pressed against the pressure-bearing portion 321 of the flexible seal 30, thereby further enhancing the sealing performance of the pressure-bearing portion 321 of the flexible seal 30 with respect to the through hole 1124.

[0062] When the storage space 114 is in a vacuum state (negative pressure state), the cover 111 will be tightly pressed against the sealing cushion 60, and it is not easy to separate the cover 111 from the first shell 112 to take out the items. At this time, the user can press the operating part 41 of the button 40 to make the button 40 overcome the elastic force of the second elastic member 100 and move from the first position to the second position. Figure 5 , Figure 5 for Figure 4 A cross-sectional schematic diagram of the button 40 in the second position.

[0063] When the button 40 moves from the first position to the second position, the push tip 423 of the extension portion 42 of the button 40 overcomes the elastic force of the first elastic member 50, and lifts and deforms the pressure-receiving 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 connected to the accommodating space 115 and the outside through the through hole 1124, and air can enter the storage space 114 from the through hole 1124, thereby releasing the vacuum state of the storage space 114, so that the cover 111 can be easily separated from the first shell 112, so that the user can take out the items.

[0064] After releasing the button 40, the second elastic member 100 drives the button 40 to return from the second position to the first position. Since the tip 423 of the button 40 is separated from the pressure-bearing portion 321 of the flexible seal 30 when in the first position, the first elastic member 50 causes the pressure-bearing portion 321 of the flexible seal 30 to close the through hole 1124.

[0065] As shown in Table 1 below, Table 1 summarizes the number of times the first elastic member 50 allows the button 40 to successfully open the through hole 1124 of the flexible seal 30 in 30 actual tests under different wire diameters of the first elastic member 50, and the number of times the first elastic member 50 allows the flexible seal 30 to close the through hole 1124 in another 30 actual tests that fall within each sealing time interval.

[0066]

[0067] From the above table, the first elastic member 50 with a wire diameter of 0.3 mm allows the button 40 to successfully open the through hole 1124 with the flexible seal 30 each time in 30 actual tests, but the first elastic member 50 with a wire diameter of 0.3 mm will fail to close the through hole 1124 for more than 2 hours in half of the other 30 actual tests. The first elastic member 50 with a wire diameter of 0.5 mm allows the button 40 to successfully open the through hole 1124 with the flexible seal 30 each time in 30 actual tests, and the first elastic member 50 with a wire diameter of 0.5 mm can close the through hole 1124 for more than 2 hours each time in the other 30 actual tests. The first elastic member 50 with a wire diameter of 0.8 mm only allows the button 40 to successfully open the through hole 1124 in only 23 out of 30 actual tests, while the first elastic member 50 with a wire diameter of 0.8 mm can make the flexible seal 30 close the through hole 1124 for more than 2 hours each time in the other 30 actual tests. The first elastic member 50 with a wire diameter of 1 mm only allows the button 40 to successfully open the through hole 1124 in only 11 out of 30 actual tests, while the first elastic member 50 with a wire diameter of 1 mm can make the flexible seal 30 close the through hole 1124 for more than 2 hours each time in the other 30 actual tests.

[0068] It can be seen from this that the wire diameter (elastic coefficient) of the first elastic member 50 cannot be too large, otherwise the tip 423 of the push button 40 will have difficulty in causing the pressure-bearing portion 321 of the flexible seal 30 to open the through hole 1124 when the button 40 is pressed. On the other hand, the wire diameter (elastic coefficient) of the first elastic member 50 cannot be too small, otherwise the elasticity of the first elastic member 50 will be offset by the elasticity of the flexible seal 30 because the flexible seal 30 is made of soft materials such as silicone or rubber, and will not be able to help the flexible seal 30 close the through hole 1124. Therefore, in the above-mentioned actual test, the first elastic member 50 with a wire diameter of 0.5 mm can ensure that each time the button 40 is pressed, the flexible seal 30 can successfully open the through hole 1124, and at the same time has sufficient elasticity to cause the flexible seal 30 to close the through hole 1124.

[0069] 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 member 50 is not only affected by the wire diameter, but also by the material, a wire diameter and material suitable for the first elastic member 50 can be selected according to actual needs to achieve the effect of enabling the button 40 to successfully open the through hole 1124 with the flexible seal 30 and having sufficient elasticity to close the through hole 1124 with the flexible seal 30.

[0070] It should be noted that the structure that allows the pressure receiving portion 321 of the flexible sealing member 30 of the button 40 to deform is not limited to a tip structure. As long as the pressure receiving portion 321 of the flexible sealing member 30 can be deformed when the button 40 moves to the second position, the tip structure can be adjusted to any suitable structure.

[0071] Next, see Figure 6 to Figure 7 , Figure 6 FIG. 4 is a partial three-dimensional schematic diagram of a vacuum storage box according to a second embodiment of the present invention. Figure 7 for Figure 6 Schematic diagram of the decomposition.

[0072] The vacuum storage box of this embodiment is similar to the one described above. Figures 1 to 5 The difference between the vacuum storage box 1 and the vacuum storage box 1 is mainly that the first elastic member 50a of the vacuum storage box of this embodiment is different. Therefore, the following is a detailed description of the first elastic member 50a of the vacuum storage box of this embodiment. Figure 6 , 7 Only part of the vacuum storage box is drawn, and the same parts between the two are not repeated and drawn again.

[0073] In this embodiment, the first elastic member 50a is a spring sheet, and the first elastic member 50a includes a bending arm 51a, a first elastic arm 52a, and a second elastic arm 53a. 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 51a. The first elastic arm 52a is fixed to the assembly seat 12 of the housing 10. The end of the second elastic arm 53a away from the bending arm 51a has an arcuate convex surface 531a, and the arcuate convex surface 531a presses against the side of the pressure receiving portion 321 of the flexible sealing member 30 away from the through hole 1124.

[0074] As shown in Table 2 below, Table 2 summarizes the number of times the first elastic member 50a allows the button 40 to successfully open the through hole 1124 of the flexible seal 30 in 30 actual tests under different thickness conditions of the first elastic member 50a, and the number of times the first elastic member 50a allows the flexible seal 30 to close the through hole 1124 in another 30 actual tests that fall within each sealing time interval.

[0075]

[0076] From the above table, the first elastic member 50a with a thickness of 0.1 mm allows the button 40 to successfully open the through hole 1124 with the flexible seal 30 each time in 30 actual tests, but the first elastic member 50a cannot close the through hole 1124 for more than 2 hours in more than half of the other 30 actual tests. The first elastic member 50a with a thickness of 0.15 mm allows the button 40 to successfully open the through hole 1124 with the flexible seal 30 each time in 30 actual tests, and the first elastic member 50a can close the through hole 1124 for more than 2 hours each time in the other 30 actual tests. The first elastic member 50a with a thickness of 0.2 mm only allows the button 40 to enable the flexible seal 30 to successfully open the through hole 1124 in only 26 out of 30 actual tests, while the first elastic member 50a can enable the flexible seal 30 to close the through hole 1124 for more than 2 hours each time in the other 30 actual tests.

[0077] It can be seen from this that the thickness (elastic coefficient) of the first elastic member 50a cannot be too large, otherwise the tip 423 of the button 40 will have difficulty in causing the pressure-receiving portion 321 of the flexible seal 30 to open the through hole 1124 when the button 40 is pressed. On the other hand, the thickness (elastic coefficient) of the first elastic member 50a cannot be too small, otherwise the elasticity of the first elastic member 50a will be offset by the elasticity of the flexible seal 30 because the flexible seal 30 is made of a soft material such as silicone or rubber, and will not be able to help the flexible seal 30 close the through hole 1124. Therefore, in the above-mentioned actual test, the first elastic member 50a with a thickness of 0.15 mm can ensure that each time the button 40 is pressed, the flexible seal 30 can successfully open the through hole 1124, and at the same time, it has sufficient elasticity to cause the flexible seal 30 to close the through hole 1124.

[0078] 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 member 50a is not only affected by the thickness, but also by the material, a suitable thickness and material of the first elastic member 50a can be selected according to actual needs to achieve the effect that the button 40 can successfully open the through hole 1124 with the flexible seal 30 and at the same time have sufficient elasticity to close the through hole 1124 with the flexible seal 30.

[0079] Next, see Figures 8 to 9 , Figure 8 FIG. 4 is a partial three-dimensional schematic diagram of a vacuum storage box according to a third embodiment of the present invention. Fig. 9 for Figure 8 A partial stereoscopic schematic diagram from another perspective.

[0080] The vacuum storage box of this embodiment is similar to the one described above. Figures 1 to 5 The difference between the vacuum storage box 1 and the vacuum storage box 1 is mainly that the first elastic member 50b is different in form, so the following is only a detailed description of the first elastic member 50b of the vacuum storage box of this embodiment. Figure 8 , 9 Only the assembly seat 12, the first elastic member 50b and the button 40 are shown, and the vacuum storage box of this embodiment is similar to the vacuum storage box of the embodiment shown in FIG. Figures 1 to 5 The same parts among the vacuum storage boxes 1 are not described or illustrated again.

[0081] In this embodiment, the first elastic member 50b is a spring sheet, which is fixed to the button 40 and can slide relative to the assembly seat 12 together with the button 40. The first elastic member 50b has a bent tip 51b, which is used to press the pressure-receiving portion (such as the pressure-receiving portion) of the flexible seal when the button 40 is in the first position. Figure 4 The pressure receiving portion 321 of the flexible sealing member 30 is far away from the through hole (such as Figure 4 On the other hand, the bent tip 51b is used to make the button 40 leave the pressure-receiving portion of the flexible seal when the button 40 is in the second position, so as to avoid the bent tip 51b obstructing the process of the button 40 forcing the flexible seal to open the through hole.

[0082] 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 can be fixed to the assembly seat. Under such a configuration, when the button is in the first position, the bent tip of the first elastic member can still press against the pressure-receiving portion of the flexible seal; when the button is in the second position, the button forces the flexible seal to open the through hole while also causing the first elastic member to be lifted upward and deformed.

[0083] According to the vacuum storage box shown in the above embodiment, due to the design of one end of the first elastic member pressing against the flexible seal covering the through hole, when the button does not push the flexible seal, the sealing performance of the flexible seal to the through hole is strengthened, so that the storage space is not connected to the outside, thereby ensuring that the storage space is in a vacuum state. When the button pushes the flexible seal, the through hole is opened to release the vacuum state of the storage space. Therefore, it can be ensured that the vacuum storage box can effectively provide a vacuum effect to properly preserve items, and the user can easily open the vacuum storage box when it is necessary to take out items from the vacuum storage box.

[0084] Furthermore, since the coil portion has a spiral structure and the outer diameter of the coil portion is gradually reduced from the side where the coil portion presses against the pressure-bearing portion toward the side away from the pressure-bearing portion, the contact area between the coil portion and the pressure-bearing portion of the flexible seal can be increased, so that the coil portion can firmly press against the pressure-bearing portion of the flexible seal to further enhance the sealing performance of the pressure-bearing portion of the flexible seal for the through hole.

[0085] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
