Description

Technical Field

[0001] The present disclosure relates to the technical field of sealed storage, and particularly to a storage sealing structure and a vacuum storage tank. Background Art

[0002] A vacuum storage tank is a container for sealing and storing items, which is used for sealing and storing food. Different types of sealed tanks have emerged in the existing market to vacuum-store foods such as powders and solid beverages, making them less likely to get damp or deteriorate.

[0003] Currently, the vacuum storage tanks on the market do not come with a spoon by default, and an external spoon needs to be used to take out the powdered food. In particular, when the user takes the vacuum storage tank on a trip, an additional spoon needs to be carried as a tool for scooping the powdered food, which is likely to result in the spoon being lost, making the above operation rather troublesome.

[0004] To solve the above problems, the existing patent CN207725954U discloses a multi-functional tank lid, in which a fixed lid is fixed on the opening of the tank body, there is a sealing structure corresponding to the outer shape of the fixed lid, and a spoon holder is suspended below the movable tank lid for placing the spoon.

[0005] However, when the multi-functional tank lid is used to store powdered food, especially granular objects such as coffee powder, oatmeal powder, and hand-brewed coffee granules, if the tank body is already full of this food and the movable tank lid is then covered and buckled with the fixed lid, the spoon may be squeezed between the movable tank lid and the powdered food, thus there is a possibility of the spoon being deformed. Summary of the Utility Model

[0006] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a storage sealing structure and a vacuum storage tank that are more convenient for scooping powdered food and do not require the spoon to be placed inside the vacuum storage tank.

[0015] In one embodiment, the spring switch includes a switch button, a spring member, an outer peripheral semi-closed convex ring and a fixed column. The outer peripheral semi-closed convex ring is arranged on the lower cover. A part of the structure of the switch button extends along the vertical direction of the upper cover. The upper cover is convexly provided with a semi-circular convex ring. The opening of the outer peripheral semi-closed convex ring is arranged facing the opening of the semi-circular convex ring. When the upper cover and the lower cover are closed, the switch button is simultaneously located inside the outer peripheral semi-closed convex ring and the semi-circular convex ring. The two ends of the fixed column pass through the through hole of the switch button and are connected to the inner wall of the outer peripheral semi-closed convex ring.

[0033] For the convenience of understanding the present disclosure, the present disclosure will be described more comprehensively below with reference to the relevant accompanying drawings. Preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present disclosure can be understood more thoroughly and comprehensively.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present disclosure belongs. The terms used in the specification of the present disclosure herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail with reference to specific embodiments as follows:

[0037] As Figure 1 shown, it is a storage sealing structure 10 according to an embodiment of the present invention, which is used for sealing and connecting to the storage placement hole, that is, the opening, of the sealed storage tank body 21. Specifically, the connection is a screw connection. The storage sealing structure 10 includes a storage sealing cover 100, a vacuum extraction assembly 200, and a pressure recovery assembly 300.

[0038] As Figure 1 and Figure 3As shown, the storage sealing cover 100 is provided with a vacuum pumping cavity 101. Part of the vacuum pumping assembly 200 is disposed in the vacuum pumping cavity 101, and the rest is exposed to the outside. The vacuum pumping assembly 200 is used to evacuate the sealed storage tank body 21. Part of the air pressure recovery assembly 300 is disposed in the storage sealing cover 100, and the air pressure recovery assembly 300 is used to inject air into the sealed storage tank body 21 to balance the air pressure inside the sealed storage tank body 21 with the external air pressure. It can be understood that when it is necessary to extract the air inside the sealed storage tank body 21, the air can be extracted to the outside through the vacuum pumping cavity 101 by pressing the vacuum pumping assembly 200 multiple times, so that the inside of the sealed storage tank body 21 is in a vacuum state. When it is necessary to restore normal pressure, the air pressure recovery assembly 300 can be pressed to restore the air pressure inside the sealed storage tank body 21.

[0039] As Figure 1 and Figure 2 As shown, the storage sealing cover 100 includes an upper cover 110, a rotating shaft assembly 120, a spring switch 130, a magnetic connection assembly 140, a spoon 150 and a lower cover 160. The lower cover 160 is used for detachably installing on the storage placement hole. The upper cover 110 is rotatably connected to the lower cover 160 through the rotating shaft assembly 120. The spring switch 130 is disposed on the outer side of the lower cover 160, and part of the structure of the spring switch 130 extends along the vertical direction of the upper cover 110, so that the spring switch 130 is buckled on the upper cover 110 when the upper cover 110 and the lower cover 160 are closed.

[0040] The magnetic connection assembly 140 is connected to the rotating shaft assembly 120. The magnetic connection assembly 140 is disposed on the outer side of the lower cover 160, and the magnetic attraction part of the spoon 150 is magnetically connected to the outer wall of the magnetic connection assembly 140.

[0041] In this embodiment, the storage sealing structure 10 adopts an upper and lower cover 160 structure. The upper cover 110 can be opened by pressing the spring switch 130 for scooping operation, without opening the entire storage sealing structure 10, thus saving the time for opening the storage sealing structure 10 and the operation is relatively simple. When the upper cover 110 is closed to be closed with the lower cover 160, the air inside the sealed storage tank body 21 is discharged by pressing the vacuum pumping assembly 200 multiple times to achieve the vacuum storage effect. Since the magnetic attraction part of the spoon 150 is magnetically connected to the outside of the magnetic connection assembly 140, when it is necessary to use the spoon 150 to scoop powder foods such as coffee powder, only the spoon 150 needs to be removed by hand, and the spring switch 130 is pressed to open the upper cover 110 for scooping. This structure does not require the spoon 150 to be placed in the vacuum storage tank 20, and the situation where the spoon 150 is squeezed between the upper cover 110 and the powder food will not occur.

[0042] As Figure 1 and Figure 3As shown, in one embodiment, the storage sealing structure 10 further includes an internal sensor 400. The internal sensor 400 is disposed on the vacuum extraction assembly 200. The vacuum extraction assembly 200 is provided with an induction through-hole 201. The vacuum extraction chamber 101, the induction through-hole 201, and the induction area of the internal sensor 400 are sequentially communicated, so that the internal sensor 400 displays the state information inside the sealed storage tank body 21. In this embodiment, the internal sensor 400 is a barometric pressure sensor. It can be understood that the barometric pressure sensor is used to detect the barometric pressure information inside the sealed storage tank body 21. When the vacuum extraction assembly 200 is pressed, the pointer of the barometric pressure sensor points to a lower barometric pressure value to display the vacuum state inside the sealed storage tank body 21; when the pressure recovery assembly 300 is long-pressed, the pointer of the barometric pressure sensor points to a higher barometric pressure value until the pointer points to the atmospheric pressure value (not shown in the drawings) to display the atmospheric pressure state inside the sealed storage tank body 21. Of course, the internal sensor 400 is not limited to the barometric pressure sensor, such as a temperature sensor or a humidity sensor.

[0043] As Figure 2 , Figure 6 and Figure 7 shown, in one embodiment, the rotating shaft assembly 120 includes a movable convex block 121, a fixed convex block 122, a torsion spring member 123, and a rotating column 124. The movable convex block 121 is disposed on the outer side of the upper cover 110, and the fixed convex block 122 is disposed on the outer side of the lower cover 160. The fixed convex block 122 is connected to the magnetic connection assembly 140. The torsion spring member 123 is disposed between the movable convex block 121 and the fixed convex block 122. The rotating column 124 passes through the through-hole of the fixed convex block 122, the torsion spring member 123, and the through-hole of the movable convex block 121, so that the upper cover 110 is rotatably connected to the lower cover 160 with the rotating column 124 as the rotation center. The two ends of the torsion spring member 123 are respectively abutted against the movable convex block 121 and the fixed convex block 122, so that when the spring switch 130 is pressed to open the upper cover 110, the upper cover 110 is opened to a certain angle by the action of the torsion spring member 123. Specifically, when opened to a certain angle, the movable convex block 121 abuts against the fixed convex block 122, and this angle is 90°. The effect diagram is as Figure 5 shown. Further, as Figure 7 shown, the fixed convex block 122 is provided with a receiving groove 1221, and the torsion spring member 123 is located in the receiving groove 1221, so that the flatness of the entire rotating shaft assembly 120 is better.

[0044] As Figure 3As shown, in one embodiment, the magnetic connection assembly 140 includes a magnetic connection housing 141 and a magnetic attraction member 142. An accommodation groove 1411 is formed in the magnetic connection housing 141, and the magnetic attraction member 142 is located in the accommodation groove 1411, so that the magnetic attraction part of the spoon 150 is magnetically connected to the magnetic connection housing 141 through the magnetic attraction member 142. It can be understood that when it is necessary to remove the spoon 150 to scoop powder-like food, it can be removed manually; after use, just put the spoon 150 back in place. At this time, the magnetic attraction part of the spoon 150 is magnetically connected to the magnetic connection housing 141 through the magnetic attraction member 142 to complete the placement action. In this embodiment, as Figure 6 and Figure 7 shown, a receiving groove 1412 is formed on the outer side of the magnetic connection housing 141. The receiving groove 1412 is used to receive the magnetic attraction part of the spoon 150 to play a guiding role when the spoon 150 is magnetically connected to the magnetic connection housing 141.

[0045] As Figures 4 to 6 shown, in one embodiment, the spring switch 130 includes a switch button 131, a spring member 132, an outer peripheral semi-closed convex ring 133 and a fixing column 134. The outer peripheral semi-closed convex ring 133 is provided on the lower cover 160. A part of the structure of the switch button 131 extends along the vertical direction of the upper cover 110. The effect diagram is as Figure 5 and Figure 6 shown. As Figure 2 and Figure 5 shown, the upper cover 110 is convex with a semi-circular convex ring 111. The opening of the outer peripheral semi-closed convex ring 133 is arranged facing the opening of the semi-circular convex ring 111 to form an outer peripheral convex ring when the upper cover 110 and the lower cover 160 are closed. The switch button 131 is located inside the outer peripheral convex ring, that is, inside both the outer peripheral semi-closed convex ring 133 and the semi-circular convex ring 111. Both ends of the fixing column 134 pass through the through hole of the switch button 131 and are connected to the inner wall of the outer peripheral semi-closed convex ring 133. The spring member 132 is located inside the outer peripheral semi-closed convex ring 133. Both ends of the spring member 132 respectively abut against the lower cover 160 and the switch button 131. Further, the switch button 131 is convex with a positioning column 1311. A positioning groove 1331 is formed in the outer peripheral semi-closed convex ring 133. One end of the spring member 132 is located in the positioning groove 1331, and the other end of the spring member 132 is sleeved on the positioning column 1311, so that the spring member 132 plays a fixing role.

[0046] It can be understood that when the upper cover 110 is closed with the lower cover 160, the outer peripheral semi-closed convex ring 133 and the semi-circular convex ring 111 can form an outer peripheral convex ring, and the switch button 131 is located within the outer peripheral convex ring. When the upper cover 110 is opened, by applying manual force to press the switch button 131, it rotates around the fixed column 134 as the rotation center. At this time, the spring member 132 is compressed, and the spring button no longer latches onto the upper cover 110, causing the upper cover 110 to rotate away from the lower cover 160 to complete the operation of opening the upper cover 110. After the manual force disappears, the spring member 132 applies force outward to the switch button 131 to restore the state of the switch button 131. Among them, under the action of the outer peripheral convex ring and the fixed column 134, the switch button 131 will not shift or even detach from the outer peripheral convex ring. When the upper cover 110 is opened, a part of the structure of the switch button 131 extends upward.

[0047] Furthermore, in combination with Figure 4 and Figure 8 As shown, a latching groove 1111 is provided in the semi-circular convex ring 111, and the switch button 131 protrudes with a latching portion 1312. The latching portion 1312 is located within the latching groove 1111 so that the switch button 131 latches onto the upper cover 110 when the upper cover 110 and the lower cover 160 are closed. It can be understood that when the upper cover 110 and the lower cover 160 are closed, the switch button 131 is located within the latching groove 1111 through the latching portion 1312 to latch onto the upper cover 110, avoiding the situation where the upper cover 110 is suddenly opened; when the upper cover 110 is opened, the switch button 131 is pressed, causing the latching portion 1312 to move away from the latching groove 1111, so that the upper cover 110 rotates away from the lower cover 160 to complete the operation of opening the upper cover 110.

[0048] Furthermore, as shown in Figure 4 The switch button 131 is provided with an avoidance notch 1313. It can be understood that when the switch button 131 is pressed to compress the spring member 132, the switch button 131 rotates around the fixed column 134 as the rotation center, causing the latching portion 1312 to move away from the latching groove 1111. Among them, the avoidance notch 1313 plays an avoidance role, enabling the latching portion 1312 to move away from the latching groove 1111 at a certain rotation angle to open the upper cover 110.

[0049] As shown in Figure 3 and Figure 5As shown, in one embodiment, the storage sealing structure 10 further includes an upper and lower cover sealing ring 500. The upper and lower cover sealing ring 500 is disposed around the inner peripheral side of the upper cover 110 and faces the lower cover 160. A sealing convex ring 161 protrudes from the peripheral side of the lower cover 160. The upper and lower cover sealing ring 500 is in interference fit with the sealing convex ring 161, so that the upper cover 110 and the lower cover 160 are completely closed through the spring switch 130. It can be understood that the upper and lower cover sealing ring 500 is used for sealing, so that external air cannot enter the sealed storage tank main body 21. Specifically, when the upper cover 110 and the lower cover 160 are closed, the upper and lower cover sealing ring 500 is in interference fit with the sealing convex ring 161 to play a sealing role, so that the upper cover 110 and the lower cover 160 are sealed and closed, and external air cannot pass through between the upper cover 110 and the lower cover 160 and enter the sealed storage tank main body 21, ensuring that the food in the sealed storage tank main body 21 is not easily affected by moisture or deterioration.

[0050] As Figure 3 shown, in one embodiment, the storage sealing structure 10 further includes a sealing ring 600 for the mouth. The sealing ring 600 for the mouth is disposed around the inner peripheral side of the lower cover 160 and faces the storage placement hole. The sealing ring 600 for the mouth is used for interference fit with the periphery of the storage placement hole, so that the storage sealing structure 10 is hermetically screwed to the sealed storage tank main body 21. In this embodiment, the sealing ring 600 for the mouth faces the storage placement hole of the sealed storage tank main body 21. When the storage sealing structure 10 is screwed to the sealed storage tank main body 21, the storage sealing structure 10 abuts against the periphery of the storage placement hole through the sealing ring 600 for the mouth, so as to achieve the effect of blocking the sealed storage tank main body 21 and prevent external air from entering the sealed storage tank main body 21.

[0051] As Figure 9 shown, the present disclosure further provides a vacuum storage tank 20, including a sealed storage tank main body 21 and the storage sealing structure 10 of any one of the above embodiments. The storage sealing structure 10 blocks the sealed storage tank main body 21, so that the sealed storage tank main body 21 and the storage sealing structure 10 are completely closed. The inner cavity of the sealed storage tank main body 21 is communicated with the vacuum pumping cavity 101 through the storage placement hole. It can be understood that when air extraction operation is required, the air in the sealed storage tank main body 21 can be pumped out through the vacuum pumping cavity 101 by pressing the vacuum extraction assembly 200 multiple times; in the normal state, the upper cover 110 and the lower cover 160 are hermetically closed, so that the storage sealing structure 10 and the sealed storage tank main body 21 are completely closed, and air will not flow out of the sealed storage tank main body 21, and external air will not enter the sealed storage tank main body 21. In this embodiment, the sealed storage tank main body 21 is made of glass or metal.

[0052] Further, the vacuum storage tank 20 further includes a label sticker 22, which is adhered to the outer wall of the sealed storage tank body 21. It can be understood that when food is placed into the sealed storage tank body 21 and sealed, the label is placed into the label sticker 22, and the label can be used to record the name of the stored food and the storage time, so that the user can understand the corresponding information.

[0053] Compared with the prior art, the present disclosure has at least the following advantages:

[0054] The above-mentioned storage and sealing structure 10 adopts an upper and lower cover 160 structure. By pressing the spring switch 130, the upper cover 110 can be opened for scooping operation without opening the entire storage and sealing structure 10, thus saving the time for opening the storage and sealing structure 10 and making the operation relatively simple; when the upper cover 110 is closed and closed with the lower cover 160, by pressing the vacuum extraction component 200 multiple times, the air in the sealed storage tank body 21 is discharged to achieve a vacuum storage effect. Since the magnetic attraction part of the spoon 150 is magnetically connected to the outside of the magnetic connection component 140, when it is necessary to use the spoon 150 to scoop powder foods such as coffee powder, the user only needs to remove the spoon 150 by hand and press the spring switch 130 to open the upper cover 110 for scooping. This structure does not require the spoon 150 to be placed in the vacuum storage tank 20, and the situation where the spoon 150 is squeezed between the upper cover 110 and the powder food will not occur.

[0055] The above-described embodiments merely represent several implementation manners of the present disclosure, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
