The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the terms "and / or" includes any and all combinations of one or more of the associated listed items.

[0041] In this application, the terms "first", "second", etc. are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, order of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0042] Referring to Figures 1-7 The present application provides a cold brewing kettle 1000, comprising a kettle body 100 and a filter bottle 200, the kettle body 100 comprises a kettle body 110 and a kettle cover 120, the top of the kettle body 110 is provided with a first opening 111, and the kettle cover 120 is partially inserted into the kettle body 110 from the first opening 111, and a first sealing ring 310 is arranged between the two.

[0043] The filter bottle 200 is placed in the kettle body 100, and the filter bottle 200 comprises a bottle body 210 and a bottle cover 220. The side wall of the bottle body 210 is hollow and has a filter screen (not shown in the figure) built-in. The top of the bottle body 210 is provided with a second opening 211, and the bottle cover 220 is partially inserted into the bottle body 210 from the second opening 211, and a second sealing ring 320 is arranged between the two.

[0044] Wherein, the cold brew kettle is placed on the table top, the installation mode of the kettle cover 120 and the bottle cover 220 is from top to bottom, and the disassembly direction is opposite. The structural configuration of the first sealing ring 310 and the second sealing ring 320 is as follows:

[0045] The first sealing ring 310 comprises a first annular portion 311, and a first lip portion 312 arranged upwardly inclined on the outer circumferential surface of the first annular portion 311, and / or the second sealing ring 320 comprises a second annular portion 321 and a second lip portion 322 arranged upwardly inclined on the outer circumferential surface of the second annular portion 321.

[0046] For the "upwardly inclined arrangement", it is understood that when the kettle cover 120 and the kettle body 110 are separated, and the bottle cover 220 and the bottle body 210 are separated, the lip portion has a tendency to extend upwardly along the radial direction of the corresponding sealing ring from inside to outside. When the kettle cover 120 and / or the bottle cover 220 are installed, the edge of the lip portion is adaptively deformed under the action of the corresponding opening to facilitate installation. When pulled out, since the extension direction of the lip portion is opposite to the pulling direction, the friction force between the wall where the opening is located and the edge of the lip portion is transmitted to the root of the lip portion, the lip portion deforms and accumulates at the root, increasing the radial force of the lip portion on the opening, thereby further increasing the friction force between the opening and the lip portion, improving the fitting strength between the kettle cover 120 and the kettle body 110, and the fitting strength between the bottle cover 220 and the bottle body 210, and avoiding the kettle cover 120 and / or the bottle cover 220 from being accidentally pulled out. For "fitting strength", it can also be called connection strength, but compared with the prior art, the kettle cover and the kettle body are not directly connected, but are indirectly connected through the first sealing ring, so the fitting strength is more appropriate. The same applies to the bottle cover and the bottle body.

[0047] When the friction force is large enough, the bottle cover 220 can be gripped to lift the entire bottle body 210, to facilitate the replacement of the internal filter, cleaning operation or addition of cold brew. Similarly, when the friction force is large enough, the kettle cover 120 can be gripped to lift the entire kettle body 110. It should be noted that the kettle body 110 is in a full load state at this time. It should be noted that the "full load state" corresponds to the internal liquid not exceeding the top of the internal bottle body 210. In the illustration, the outer periphery of the kettle body 100 is provided with a handle 150, which can also be used to lift the kettle body 100.

[0048] The kettle cover 120 is provided with a first groove for embedding the first annular part 311, and the bottle cover 220 is provided with a second groove for embedding the second annular part 321. The outer diameter of the first sealing ring 310 is greater than the inner diameter of the first opening 111, and the outer diameter of the second sealing ring 320 is greater than the inner diameter of the second opening 211, so that after the kettle cover 120 and the bottle cover 220 are installed, the sealing ring is deformed to generate sufficient force on the corresponding opening and play an effective sealing role. It should be noted that the sealing of the first sealing ring 310 is to prevent the liquid in the kettle body 110 from leaking out, and the second sealing ring 320 is to prevent the cold-brewed coffee in the bottle body 210 from leaking out.

[0049] In an embodiment, the first lip 312 and the second lip 322 gradually decrease in thickness from inside to outside along the radial direction of the respective sealing ring, which is conducive to the deformation of the lip edge and further facilitates installation, while facilitating demolding production. Among them, the first lip 312 and the second lip 322 have an upper surface 410 and a lower surface 420 along the axial direction of the respective sealing ring, combined with the above-mentioned Figure 6 Taking the first sealing ring 310 as an example, the lower surface 420 is inclined upward and has a first slope, and the upper surface 410 is inclined upward and has a second slope, and the second slope is smaller than the first slope. Among them, the upper surface 410 or the lower surface 420 is an arc surface or an inclined surface, which allows the upper surface 410 to be a plane, i.e. the slope is 0.

[0050] Among them, the first lip 312 in the figure is arranged in multiple along the axial direction, and the inclination angles of each first lip 312 are different, i.e. the same or different between each first lip 312. The "same" is reflected in that the outer diameter size, the first slope and the second slope are all the same, and the "different" is reflected in that any of the above parameters is different. The plurality of first lips 312 can further improve the sealing performance and enhance the cooperation strength between the kettle cover 120 and the kettle body 110, which needs to be determined according to the sealing requirements, the cooperation strength, and the weight of the kettle body. For example, in the figure, the first lip 312 is three, which are upper, middle and lower, the first lips 312 located at the upper and lower are the same, the first lip 312 in the middle is different from the other two, and the slope of the upper surface of the first lip 312 is 0.

[0051] Although this application only provides a figure showing that the second lip 322 is one, the above-mentioned number and structure of the first lip 312 are also applicable to the second lip 322, for example, the second lip 322 is arranged in multiple along the axial direction, and the inclination angles of each second lip 322 are the same or different.

[0052] In another embodiment, combined with the above-mentioned Figure 7For example, the second sealing ring 320 is taken as an example, the second opening 211 is provided with a second matching area 212 matched with the second lip 322, the second matching area 212 is relatively recessed, that is, the second matching area 212 is provided with a protrusion 213 protruding outwardly above the second matching area 212, when the bottle cap 220 is pulled out, the protrusion acts on the second lip 322 in the axial direction, and can directly apply an axial force to the second sealing ring 320 to prevent the separation between the bottle cap 220 and the bottle body 210, and can further extrude the second lip 322 to deform radially inwardly, so as to further increase the force of the second lip 322 on the second opening 211.

[0053] Correspondingly, the above structure is also applicable to the first lip 312, that is, the first opening 111 is provided with a first matching area matched with the first lip 312, and the first matching area is relatively recessed.

[0054] The kettle body 110 includes a detachably connected base 130 and an upper cover 140, and a third sealing ring 330 arranged between the base 130 and the upper cover 140, the upper cover 140 has a top wall 141 and a side wall 142, the top wall 141 is provided with the first opening 111 and has an extension 113 extending downwardly from the first opening 111 and sealingly matched with the kettle cover 120. Specifically, the upper cover 140 and the base 130 are connected through buckling, after the upper cover 140 is detached, the top of the base 130 is open, the opening is larger, and cleaning is facilitated. In an embodiment, the first opening 111 is a flared opening structure, specifically a conical structure gradually shrinking inwardly from top to bottom, and the outer circle of the first annular portion 311 is parallel to the first opening 111.

[0055] The kettle cover 120 has a first pinch portion 121 protruding from the top of the kettle body 110, and the bottle cap 220 has a second pinch portion 221 protruding from the top of the bottle body 210. The kettle cover 120 is a hollow structure and the bottom is open, the second pinch portion 221 extends into the inner cavity of the kettle cover 120, and the structure is compact.

[0056] The kettle cover 120 includes an outer cover 122 matched with the kettle body 110 and axially penetrating, and an inner cover 123 arranged inside the outer cover 122, the inner cover 123 has a sealing state of closing the kettle body 100 and an open state of opening the kettle body 100. In this embodiment, the inner cover 123 and the outer cover 122 are threadedly connected, and the open state is not that the inner cover 123 completely separates from the outer cover 122, but as long as the liquid in the kettle body 100 can be poured out through the outer cover 122.

[0057] The actual use mode of the cold brewing kettle of the present application is: first open the kettle cover 120, then pinch the bottle cap 220 to take out the filter bottle 200 as a whole, separate the bottle cap 220 and the bottle body 210, then put the cold brewing material (such as coffee powder, tea powder, tea leaves, coffee beans, etc.) into the bottle body 210, put the bottle body 210 back into the kettle body 110, pour cold water into the bottle body 210 (wherein the cold water cannot cover the filter screen cover to avoid tea leaves and coffee beans overflowing from the bottle body 210), cover the bottle cap 220, cover the kettle cover 120, stand for extraction, rotate the inner cover 123 (the inner cover 123 does not need to be completely rotated out, and there will be a buckle structure prompt when rotating), and pour out the beverage.

[0058] In an embodiment, the first sealing ring 310 has a greater tightening force than the second sealing ring 320, the outer diameter of the bottle cap 220 is smaller than the through hole of the outer cover 122, and the actual operation further includes rotating and separating the inner cover 123 from the outer cover 122, pinching and lifting the bottle cap 220, and abutting the bottle body 210 against the bottom end of the outer cover 122. Since the first sealing ring 310 has a greater tightening force than the second sealing ring 320, the bottle cap 220 is continuously forced, and finally the bottle cap 220 and the bottle body 210 are separated, and the cold brewing material is added into the bottle body 210.

[0059] The cold brewing kettle of the present application is inserted and fitted between the kettle cover and / or bottle cap and the corresponding kettle body and bottle cap, which is convenient to install, and the lip of the sealing ring is inclined upward, so that the kettle cover and / or bottle cap are not easy to pull out, and even the kettle cover and / or bottle cap can be pinched to lift the kettle body or bottle body, which is convenient to operate.

[0060] The technical features of the above embodiments can be combined in any way. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure. When the technical features in different embodiments are embodied in the same figure, it can be considered that the figure also discloses the combination of the embodiments involved.

[0061] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application.
