DETAILED DESCRIPTION

[0026] Application Application Application The present application is further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present application and implement it, but the embodiments are not intended to limit the present application.

[0027] Please refer to Figures 1 to 3, which are respectively a schematic 3D view of the appearance of the present invention, an exploded 3D view of the vacuum cover, and a cross-sectional view of the present invention from one perspective. The present invention provides a manual vacuum storage box, comprising a box body 1 and a vacuum cover 2 assembled on the box body 1; wherein:

[0028] The box body 1 can be used to carry food that needs to be preserved or kept fresh. After the vacuum cover 2 is placed on the box body 1, the interior of the box body 1 can be vacuumed through the vacuum cover 2 to prevent the food in the box body 1 from spoiling.

[0029] As shown in Figures 2 and 3, the air extraction cover 2 comprises a cover body 20, a support base 21 disposed on the cover body 20, and an air extraction assembly 22 connected between the cover body 20 and the support base 21. The cover body 20 is used to be assembled with the box body 1 to seal the opening at the top of the box body 1. As shown in Figures 3 and 4, a sealing ring 200 may be provided on the outer edge of the cover body 20. When the cover body 20 is assembled with the box body 1, the sealing ring 200 can be in close contact between the box body 1 and the cover body 20 to achieve a sealed effect.

[0030] Referring again to Figures 2 to 4 , the lid 20 is provided with a chamber 201. The chamber 201 protrudes from the bottom of the lid 20 into the box body 1, allowing the vacuum assembly 22 to be positioned within the chamber 201. The vacuum assembly 22 comprises a piston seat 220, a triggering member 221 that is linked to the piston seat 220 via the support seat 21, and a reset element 222 that abuts between the piston seat 220 and the support seat 21. A sealing ring 220a is provided around the piston seat 220, and a linkage protrusion 220b is provided on the piston seat 220. The support seat 21 has a through hole 210 corresponding to the linkage protrusion 220b, allowing the upper edge of the linkage protrusion 220b to engage with the through hole 210 (as shown in Figure 4 ). The reset element 222 is sleeved outside the linkage protrusion 220 b and abuts between the piston seat 220 and the support seat 21 . The reset element 222 can be a compression spring.

[0031] As mentioned above, one end of the pull member 221 is provided with a pivot portion 221a and is pivotally mounted on the pivot hole 210a on the above-mentioned support base 21, and a downwardly protruding linkage portion 221b is provided at a position opposite to the through hole 210 of the support base 21, and the above-mentioned linkage protrusion 220b is further provided with a connecting portion 220c, so that the linkage portion 221b can pass through the through hole 210 and be movably connected to the connecting portion 220c of the linkage protrusion 220b, so that a person can manually pull the other end of the pull member 221, and the piston seat 220 can be driven to move upward in the chamber 201 of the cover body 20 through the pull member 221, and then the piston seat 220 is pushed downward back to the initial position by the above-mentioned reset element 222, so that the piston seat 220 can move up and down in the chamber 201 of the cover body 20. Furthermore, the support base 21 may be provided with a recessed portion 210b for the pull member 221 to lie flat therein, and a notch 210c is formed at the other end of the recessed portion 210b corresponding to the pull member 221 to facilitate a person's fingers to reach into the notch 210c to pull the pull member 221 upward.

[0032] 3 and 4 , the cover body 20 is provided with a mounting hole 202 in communication with the above-mentioned box body 1 on its chamber 201, and a valve member 23 is provided on the mounting hole 202. The valve member 23 has a main body 230 and at least one valve plate 231 extending outward from the main body 230. The main body 230 is fixed to the mounting hole 202 so that the valve plate 231 can be attached to the inner wall of the chamber 201, and the chamber 201 is provided with an air hole 203 corresponding to the valve plate 231 (as shown in FIG. 4 ). The valve plate 231 completely covers the air hole 203 so that when the above-mentioned pull member 221 drives the piston seat 220 to move up and down in the chamber 201 of the cover body 20, the air in the box body 1 can be extracted from the air hole 203 and the extracted air can be prevented from returning to the box body 1.

[0033] Therefore, by adopting the above-mentioned structure, the manual vacuum storage box of the present application can be obtained.

[0034] 5 and 6 , when a person manually pulls the pull member 221, the pull member 221 drives the piston seat 220 to move up and down in the chamber 201 of the cover body 20, so that the air in the box body 1 can be pumped into the chamber 201 through the air hole 203, and the valve plate 231 prevents the air from returning to the box body 1, thereby achieving the purpose of vacuuming the box body 1 and preserving freshness.

[0035] Furthermore, as shown in Figures 2 and 7, the present application can further provide an exhaust button 24 on the vacuum cover 2, and the exhaust button 24 includes a press key 240 and an elastic element 241, and a pressure relief hole 204 is provided on the above-mentioned cover body 20, and a press hole 210d is provided on the support base 21 corresponding to the pressure relief hole 204. The exhaust button 24 is accommodated in the press hole 210d with the press key 240, and is elastically arranged on the pressure relief hole 204 in conjunction with the elastic element 241 and tightly seals the pressure relief hole 204; thereby, when the box body 1 is in a vacuum state, by pressing the press key 240, external air can enter the box body 1 through the pressure relief hole 204, thereby the vacuum cover 2 can be removed from the box body 1, thereby facilitating the opening of the vacuum storage box.

[0036] Therefore, with the manual vacuum storage box of the present application, although the vacuum cover 2 is manually operated, the vacuum cover 2 can be combined with the support base 21 through the above-mentioned combination of the cover body 20 and the support base 21. When the vacuum is manually operated, the vacuum cover 2 can better withstand the force of the human hand through the close fit between the cover body 20 and the box body 1 and the force applied by the pull member 221 of the support base 21. Therefore, it is suitable for manual operation and improves the durability of its manual vacuum operation.

[0037] The above-described embodiments are merely preferred embodiments for the purpose of fully illustrating the present application, and the scope of protection of the present application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art based on the present application are within the scope of protection of the present application. The scope of protection of the present application shall be subject to the claims.
