Description

Technical Field

[0001] This application relates to the technical field of thermal insulation containers, and particularly to a packaging component and a thermal insulation kettle. Background Art

[0002] In existing containers such as thermal insulation kettles, there is a receiving cavity for containing liquid and a lid for sealing the receiving cavity. During use, hot water or other high-temperature liquids are placed in the receiving cavity, and then the receiving cavity is sealed with the lid to slow down the heat dissipation rate of the high-temperature liquid in the receiving cavity, thereby achieving heat preservation. Since the temperature of the liquid in the receiving cavity is relatively high, the gas in the receiving cavity absorbs heat and expands, causing the air pressure in the receiving cavity to increase, resulting in a pressure difference between the inside and outside of the receiving cavity. At this time, if you want to open the lid, you need to use a greater force, which is not convenient for users.

[0003] Some existing thermal insulation kettles set the water sealing plate in a two-section structure so that the receiving cavity can be exhausted when the lid is opened, thereby making the air pressure inside and outside the receiving cavity tend to be equal. However, when using this two-section water sealing plate, large-volume substances such as tea leaves in the receiving cavity may flow into the gap of the water sealing plate, resulting in a reduction in the sealing effect of the water sealing plate, or large-volume substances such as tea leaves may flow out through the water sealing plate. Summary of the Invention

[0004] Based on this, it is necessary to provide a packaging component and a thermal insulation kettle that can exhaust air and filter substances flowing through the packaging component.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0020] It can be understood that by using the first end surface and the second end surface with different heights to abut against the extension rod, the extension rod can be kept in two different positions, so that the accommodating cavity can be in a sealed state or an open state.

[0021] In one of the embodiments, the extension rod is fixedly connected to a chuck, the packaging element further includes a second sealing member, and an elastic member is disposed between the chuck and the second sealing member.

The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0043] Please refer to Figures 2 to 5 , this application provides a packaging component, which is used to be installed at the opening of the accommodation cavity 101. The packaging component can seal the opening of the accommodation cavity 101 so that the accommodation cavity 101 forms a closed chamber and is in a closed state. Alternatively, the packaging component can partially seal the accommodation cavity 101 or not seal the accommodation cavity 101, so that the accommodation cavity 101 can communicate with the outside world and is in an open state.

[0044] Specifically, the packaging component includes a housing 1, a first channel 11, a first sealing portion 21, and a second sealing portion 22. The first channel 11 is formed inside the housing 1. One end of the first channel 11 communicates with the outside world, and the other end is used to communicate with the accommodation cavity 101. For example, when the accommodation cavity 101 is in an open state, the first channel 11 communicates with the accommodation cavity 101, so that substances such as liquid or gas inside the accommodation cavity 101 can be discharged to the outside world through the first channel 11. Refer to Figure 3 , the first sealing portion 21 and the second sealing portion 22 can form a first seal 2 to be used for sealing the connection between the first channel 11 and the accommodation cavity 101, so that the accommodation cavity 101 is in a closed state. In addition, refer to Figure 4 , when the first seal 2 releases the seal of the connection between the first channel 11 and the accommodation cavity 101, the gas inside the accommodation cavity 101 can pass through the packaging component and be discharged to the outside world to achieve the exhaust operation of the accommodation cavity 101.

[0045] Refer to Figure 4 and Figure 6, on the side of the first sealing portion 21 facing the first channel 11, an exhaust chamber 211 is formed, and the first sealing portion 21 is provided with exhaust holes 212 that can communicate the accommodation chamber 101 and the exhaust chamber 211. The exhaust holes 212 can be holes penetrating through the first sealing portion 21. There are multiple exhaust holes 212, and the multiple exhaust holes 212 are equally spaced. For example, the multiple exhaust holes 212 are annularly arrayed around the second sealing portion 22. The first sealing portion 21 is used to separate the exhaust chamber 211 and the accommodation chamber 101. For example, the first sealing portion 21 is in direct or indirect contact with the housing 1 forming the first channel 11. At this time, only the accommodation chamber 101 and the exhaust chamber 211 can communicate through the exhaust holes 212, and the gas in the accommodation chamber 101 flows into the exhaust chamber 211 through the exhaust holes 212; moreover, due to the small aperture of the exhaust holes 212, large-volume objects such as tea leaves in the accommodation chamber 101 cannot or are difficult to pass through the exhaust holes 212. Thus, it is possible to filter the substances flowing into the exhaust chamber 211, that is, flowing into the encapsulation element, prevent large-volume substances such as tea leaves from flowing into the encapsulation element and affecting the sealing performance of the encapsulation element, and prevent large-volume substances such as tea leaves from flowing out of the encapsulation element.

[0046] The second sealing portion 22 can be in direct or indirect contact with the housing 1 forming the first channel 11 to hermetically separate the first channel 11 and the exhaust chamber 211. When the second sealing portion 22 hermetically separates the first channel 11 and the exhaust chamber 211, the exhaust holes 212 communicating with the exhaust chamber 211 are hermetically separated from the first channel 11. At this time, the accommodation chamber 101 is in a sealed state; when the second sealing portion 22 is separated from the housing 1, that is, after the second sealing portion 22 is separated from the first channel 11, the first channel 11 is communicated with the exhaust chamber 211, and thus is connected to the exhaust holes 212. At this time, the gas in the accommodation chamber 101 can flow out to the outside in sequence through the exhaust holes 212, the exhaust chamber 211, and the first channel 11, thereby realizing the exhaust operation of the accommodation chamber 101.

[0047] In one embodiment, the encapsulation element further includes a second seal 3, which is disposed between the first seal 2 and the first channel 11, and the second seal 3 can directly or indirectly abut against the housing 1 to partially seal the first channel 11. For example, the second seal 3 is provided with a through hole 31 penetrating through the second seal 3, and the through hole 31 can communicate the first channel 11 and the exhaust chamber 211. When the second seal 3 abuts against the housing 1, the first channel 11 can only communicate with spaces such as the exhaust chamber 211 through the through hole 31. Wherein, the second seal 3 can directly abut against the housing 1, and the first sealing portion 21 and the second sealing portion 22 of the first seal 2 indirectly abut against the housing 1 through the second seal 3 respectively. For example, the first sealing portion 21 abuts against the second seal 3, and the inner wall of the first sealing portion 21 facing the first channel 11 and the partial end face of the second seal 3 facing the first sealing portion 21 enclose the exhaust chamber 211; the second sealing portion 22 can abut against the second seal 3 to seal the through hole 31 of the second seal 3 and make the accommodation cavity 101 in a sealed state, or the second sealing portion 22 can be separated from the second seal 3 to enable the first channel 11 to communicate with the exhaust hole 212 for exhaust operation.

[0048] In one embodiment, the first sealing portion 21 can be an elastic sealing portion. For example, the first sealing portion 21 can be prepared from an elastic material such as silica gel, so that the first sealing portion 21 can be deformed by extrusion. The first sealing portion 21 can be connected to the second sealing portion 22. For example, the first sealing portion 21 and the second sealing portion 22 are integrally formed of the same material, so that the first sealing portion 21 can move following the second sealing portion 22. When the second sealing portion 22 is separated from the second seal 3, the first sealing portion 21 can abut against the second seal 3; when the second sealing portion 22 abuts against the second seal 3 to seal the through hole 31, the second sealing portion 22 will move towards the second seal 3 until it abuts tightly against the second seal 3. At the same time, the second sealing portion 22 will drive the first sealing portion 21 to move towards the second seal 3 to drive the first sealing portion 21 to extrude the second seal 3 and produce elastic deformation. Therefore, when the second sealing portion 22 is separated from or abuts against the second seal 3, the first sealing portion 21 always abuts against the second seal 3, that is, the exhaust chamber 211 remains in communication with the accommodation cavity 101 only through the exhaust hole 212, preventing the substances in the accommodation cavity 101 from entering the exhaust chamber 211 through the connection between the first sealing portion 21 and the second seal 3 without passing through the filtration of the exhaust hole 212.

[0049] In one embodiment, the second sealing portion 22 may be generally cylindrical in structure. One end of the second sealing portion 22 facing the first channel 11 forms a sealing surface 221, and the area of the sealing surface 221 is larger than the area of the through hole 31, so that when the sealing surface 221 abuts against the second seal 3, the through hole 31 of the second seal 3 can be completely sealed. The first sealing portion 21 is disposed around the outer periphery of the sealing surface 221, and the first sealing portion 21 is generally disc-shaped; when the first sealing portion 21 is in a relaxed state, that is, when the first sealing portion 21 does not undergo elastic deformation, the first sealing portion 21 protrudes from the sealing surface 221 in the direction toward the through hole 31. Therefore, when the first sealing portion 21 is initially in contact with the second seal 3, the sealing surface 221 of the second sealing portion 22 is separated from the second seal 3, and at this time, the accommodating cavity 101 is in an open state; when the sealing surface 221 of the second sealing portion 22 abuts against the second seal 3, the first sealing portion 21 is pressed against the second seal 3 and undergoes elastic deformation, and at this time, the accommodating cavity 101 is in a sealed state.

[0050] Referring to Figures 2 to 5 , in one embodiment, the encapsulation element further includes a driving assembly. The driving assembly may be connected to the second sealing portion 22 to drive the second sealing portion 22 to seal the through hole 31 or drive the second sealing portion 22 to separate from the through hole 31. Therefore, the user can control the driving assembly to separate the second sealing portion 22 from the through hole 31 to exhaust the accommodating cavity 101, or control the driving assembly to seal the through hole 31 by the second sealing portion 22 to seal the accommodating cavity 101.

[0051] In one embodiment, the driving assembly includes a control unit 41 and an extension rod 42. One end of the extension rod 42 is connected to the control unit 41. For example, the extension rod 42 abuts against the control unit 41; the other end of the extension rod 42 passes through the through hole 31 and is connected to the second sealing portion 22. For example, the second sealing portion 22 covers the end face of the extension rod 42, and the extension rod 42 has a clearance fit with the through hole 31. The control unit 41 is disposed at one end of the encapsulation element facing the outside, so that at least a part of the control unit 41 is exposed to the outside, thereby facilitating the user to operate the control unit 41. The user can operate the control unit 41 to drive the extension rod 42 and the second sealing portion 22 connected to the extension rod 42 to move, so that the second sealing portion 22 moves toward the second seal 3 under the control of the control unit 41 to seal the through hole 31, or moves away from the second seal 3 under the control of the control unit 41 to communicate the through hole 31 with the exhaust hole 212 for exhausting.

[0052] In one embodiment, the control unit 41 includes a board body 413 and a toggling member 412. The board body 413 is fixedly connected to the housing 1, and a moving groove 411 is formed on the board body 413 and extends in a direction perpendicular to the extending direction of the extending rod 42. A part of the toggling member 412 is received in the moving groove 411 so that the toggling member 412 can move along the extending direction of the moving groove 411; another part of the toggling member 412 can protrude out of the board body 413 so that a user can operate the part of the toggling member 412 protruding out of the board body 413 to drive the toggling member 412 to move. One end of the toggling member 412 facing the extending rod 42 is provided with a first end face 4121 and a second end face 4122. In the extending direction of the extending rod 42, the first end face 4121 and the second end face 4122 are at different heights, and the first end face 4121 and the second end face 4122 are respectively used for abutting against the extending rod 42; for example, in the extending direction of the extending rod 42, the first end face 4121 is closer to the second sealing portion 22 than the second end face 4122, that is, the first end face 4121 is lower than the second end face 4122. When the extending rod 42 abuts against the first end face 4121, the second sealing portion 22 connected to the extending rod 42 is separated from the second sealing member 3; when the extending rod 42 abuts against the second end face 4122, since the second end face 4122 is higher than the first end face 4121, the height of the extending rod 42 increases when it moves from abutting against the first end face 4121 to abutting against the second end face 4122, and the height of the second sealing portion 22 connected to the extending rod 42 increases and gradually moves towards the second sealing member 3 until it is in sealing abutment with the second sealing member 3.

[0053] In one embodiment, a chuck 421 is fixedly connected to the extending rod 42. For example, the extending rod 42 is provided with a card slot, and the chuck 421 is arranged in the card slot. An elastic member 422 can be arranged between the chuck 421 and the second sealing member 3. The elastic member 422 is used to drive the extending rod 42 to abut against the toggling member 412, and the elastic member 422 has a pre-compression amount between the chuck 421 and the second sealing member 3. Among them, the elastic member 422 can specifically be a spring.

[0054] In this embodiment, the sealing chamber 101 of the packaging element contains a high-temperature liquid, and the air pressure in the chamber 101 is greater than the external air pressure after the chamber 101 is sealed for a period of time. When the chamber 101 needs to be sealed, the elastic deformation trend generated by the elastic member 422 drives the extension rod 42 to move toward the toggle member 412 and abut against the second end surface 4122 through the chuck 421. At this time, the extension rod 42 drives the second sealing portion 22 to move toward the second sealing member 3 to abut against the second sealing member 3, and the second sealing member 3 is squeezed by the first sealing member 2 and abuts against the housing 1. When it is necessary to vent the accommodating chamber 101 and put the accommodating chamber 101 in an open state, when the first end face 4121 of the operating toggle member 412 abuts against the extension rod 42, since the first end face 4121 is lower than the second end face 4122, the extension rod 42 will move downward to squeeze the elastic member 422 and make the second sealing portion 22 connected to the extension rod 42 away from the second sealing member 3. At this time, the gas in the accommodating chamber 101 can be discharged to the outside through the exhaust hole 212, the exhaust chamber 211, the through hole 31, and the first channel 11; and since the air pressure in the accommodating chamber 101 is relatively high, the gas in the accommodating chamber 101 will press the second sealing member 3 against the shell 1 and prevent the elastic member 422 from releasing its elastic potential energy. After the gas in the accommodating chamber 101 is discharged for a period of time, the air pressure in the accommodating chamber 101 decreases, and the squeezing effect of the gas in the accommodating chamber 101 on the second sealing member 3 disappears or weakens. At this time, the elastic member 422 drives the second sealing member 3 away from the shell 1 to make the first channel 11 fully open.

[0055] Reference Figure 1 The present application also provides a thermos pot, which includes a pot body 100 and a cover body 200. A receiving chamber 101 is formed in the pot body 100, and a filter cover 102 having a plurality of filter holes can also be accommodated in the housing 1, and the filter cover 102 is arranged in the receiving chamber 101. The receiving chamber 101 can be used to accommodate high-temperature liquids such as hot water, and the filter cover 102 can be used to accommodate soaked objects such as tea leaves, and the filter cover 102 is covered on the second sealing member 3 and accommodates at least part of the first sealing member 2, and the minimum size of the soaked object is larger than the aperture of the exhaust hole 212, so that the exhaust hole 212 can completely filter the soaked object and prevent the soaked object from being discharged from the exhaust hole 212. In other embodiments, the size of a small-sized soaked object such as tea leaves can be smaller than the aperture of the exhaust hole 212, and the small-sized soaked objects such as tea leaves can be discharged through the exhaust hole 212, while the large-sized soaked objects are filtered by the exhaust hole 212.

[0056] The cover 200 includes the above-mentioned packaging element, which is installed at the opening of the accommodating chamber 101 to seal or open the accommodating chamber 101. When the accommodating chamber 101 needs to be sealed, the toggle member 412 is driven to make the second end face 4122 abut against the extension rod 42; when the accommodating chamber 101 needs to be opened, the toggle member 412 is driven to make the first end face 4121 abut against the extension rod 42, and at this time, the gas is discharged from the exhaust hole 212, and after the gas is discharged for a period of time, the second sealing member 3 is automatically separated from the housing 1, so that the first channel 11 is fully opened, and the liquid in the accommodating chamber 101 can be poured out.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
