[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] Please refer to Figures 1-4 A cup body structure of an electric heating cup, comprising an outer shell 1, an inner container 2 and an intermediate transition piece 3, the intermediate transition piece 3 forms a connecting transition of the outer shell 1 and the inner container 2 at a cup opening.

[0037] The outer shell 1 has an outer cup opening 101, an outer cup neck 102, an outer cup shoulder 103 and an outer cup body 104 arranged in sequence from top to bottom. The inner container 2 has an inner cup opening 201, an inner cup neck 202, an inner cup shoulder 203, an inner cup body 204 and an inner cup bottom 205 arranged in sequence from top to bottom.

[0038] After the outer shell 1, the inner container 2 and the intermediate transition piece 3 are assembled, the top of the inner cup opening 201 is higher than the top of the outer cup opening 101 to form a height difference.

[0039] As shown in Figure 2 , 3 The intermediate transition piece 3 is sleeved on the inner cup opening 201 and the inner cup neck 202, the top of the intermediate transition piece 3 is engaged with the inner cup opening 201, and the middle part of the intermediate transition piece 3 is engaged with the outer cup opening 101.

[0040] The outer shell is a part connected and covered by an externally connected cup cover, and the transition connection of the outer shell and the inner container is formed by the intermediate transition piece, so that when the outer shell has stains or sewage, it is not easy to directly flow to the inner cup opening of the inner container, effectively ensuring the hygiene of the liquid in the inner container.

[0041] In some embodiments, the outer shell can be made of PP material, the intermediate transition piece can be made of SUS304 material, and the inner liner can be made of SUS306L material.

[0042] In some embodiments, the top edge of the inner cup mouth 201 is turned outward and extended downward to form a joint skirt 206, and the inner side of the top of the intermediate transition piece is fitted to the outer side of the joint skirt 206.

[0043] Preferably, the joint skirt 206 and the part of the top of the inner cup mouth 201 close to the joint skirt form a top thermal insulation cavity 207 on the inner side of the joint skirt.

[0044] In some embodiments, the intermediate transition piece 3 has, from top to bottom, a transition top 301 (i.e. the top of the intermediate transition piece described above), a height difference eliminating part 302, a transition middle 303 (i.e. the middle of the intermediate transition piece described above), an extension part 304, and a transition bottom 305.

[0045] The inner side of the transition top 301 is fitted to the outer side of the joint skirt 206. The height difference eliminating part 302, the transition middle 303, the extension part 304, and the transition bottom 305 all have gaps with the inner cup mouth 301 and the inner cup neck 202 to form a transition thermal insulation cavity 306 in communication with the top thermal insulation cavity 207.

[0046] The height difference eliminating part 302 is configured to be gradually outwardly expanded from top to bottom (or gradually inwardly contracted from bottom to top) to form an outer guide slope.

[0047] The top of the extension part 304 has a smaller diameter than the transition middle 303 to form a diameter difference, thereby forming a limiting step 307.

[0048] The outer side of the transition middle 303 is fitted to the inner side of the top of the outer cup mouth 101.

[0049] The inner side of the outer cup mouth 101 is formed with a limiting block 105 corresponding to the limiting step 307, which is used to abut against the limiting step 307 when the outer side of the transition middle 303 is tightly fitted to the inner side of the top of the outer cup mouth 101 to limit the downward movement of the transition middle 303.

[0050] The part of the inner cup shoulder 203 close to the inner cup neck 202 has a bearing platform 208 corresponding to the transition bottom 305, and the bottom edge of the transition bottom 305 is turned outward and extended horizontally to form a connecting wing plate 308. The bottom of the outer cup mouth 101 and / or the outer cup neck 102 is extended downward to form a top pressing wing plate 106 corresponding to the connecting wing plate 308.

[0051] Preferably, the outer edge of the connecting wing plate 308 is turned outward and extended downward to form a support skirt 309 corresponding to the inner cup shoulder 203.

[0052] Preferably, a first sealing gasket 4 is provided between the top pressure wing plate 106 and the connecting wing plate 308.

[0053] Preferably, a second sealing gasket (not shown) is provided between the foundation and the bottom of the transition.

[0054] like Figure 3 As shown, a first sealing gasket 4 is provided between the top pressure wing plate 106 and the connecting wing plate 308. When assembling the intermediate transition piece 3 and the outer shell 1, one assembly method is as follows: First, the first sealing gasket 4 is placed on the transition bottom 305 from top to bottom and supported by the connecting wing plate 308. Then, the intermediate transition piece 3 is inserted into the outer shell 1 from the outer cup body 104 upwards, and the height difference elimination part 302 is squeezed through the limiting block 105 and then passes out from the outer cup opening 101, so that the transition middle part 303 fits with the inner side of the top of the outer cup opening 101, and the limiting block 105 and the limiting step 307 abut against each other, and the first sealing gasket 4 is pressed tightly onto the connecting wing plate 308 by the top pressure wing plate 106.

[0055] On the one hand, it can limit the upper and lower positions of the intermediate transition piece 3, ensuring the stability of the intermediate transition piece 3 on the outer shell 1. The first sealing gasket 4 can be selected as a sealing gasket with a certain elastic deformation capability, such as an elastic rubber sealing gasket or an elastic silicone sealing gasket, thereby making the upper and lower limiting effect of the intermediate transition piece 3 better. On the other hand, the first sealing gasket 4 can effectively prevent water from seeping into the heat insulation cavity between the outer cup mouth 101 and the transition middle part 303 and reaching the inner cup body. Therefore, it is possible to choose to weld and seal the contact position between the outer cup mouth 101 and the transition middle part 303 or not to weld and seal it, both of which can ensure good waterproof capability.

[0056] Preferably, the bottom side of the limiting block 105 is inclined to cooperate with the outer guide slope formed by the height difference elimination part 302.

[0057] Preferably, at least the height difference elimination part 302 has a certain elastic deformation property so that when the intermediate transition part 3 is assembled with the outer shell 1, the height difference elimination part 302 can smoothly squeeze through the protrusion of the limiting block 105, such as a height difference elimination part with a thickness of less than 1 mm made of SUS304.

[0058] Similarly, when the second sealing gasket is provided between the support and the transition bottom, during the assembly of the intermediate transition and the inner container, one of the assembly methods is that the second sealing gasket is first sleeved on the inner cup shoulder from top to bottom and supported by the support, and then the inner cup mouth is sleeved in the intermediate transition from bottom to top, and the engaging skirt is engaged with the inner side of the transition top.

[0059] In some embodiments, the inner side of the outer cup body 104 is formed with a plurality of positioning flaps 107 arranged in the up-down direction, and the side of the plurality of positioning flaps 107 is arranged around the inner cup body 204 to correspondingly position the inner cup body 204.

[0060] The bottom of the positioning flaps 107 forms a sealing ring positioning portion 108, which is combined with the inner side of the bottom of the outer cup body 104 and the outer side of the bottom of the inner cup body 204 to form a downwardly open positioning groove 109, and the positioning groove 109 is provided with a sealing ring 5 around the outer cup body 104 and the inner cup body 204.

[0061] In the present embodiment, the bottom of the outer cup body 104 is further connected with an outer bottom shell 6, which covers the inner cup bottom 205 and forms a mounting cavity 7 between the outer bottom shell 6 and the inner cup bottom 205.

[0062] In some embodiments, as an electric heating cup that can heat the liquid (such as water, milk) contained in the inner container, the electric heating assembly for heating is mounted in the mounting cavity 7.

[0063] In some embodiments, the outer bottom shell 6 is connected to the outer cup body 104 from bottom to top.

[0064] Preferably, the outer bottom shell 6 is connected with a heat shield 8 for pressing the sealing ring 5 from bottom to top in the positioning groove 109.

[0065] In some embodiments, the heating body 9 of the electric heating assembly is close to the bottom side of the inner cup bottom 205, and constitutes a heat shield 8 for shielding the heating body 9, which means that the heat shield 8 can separate the mounting cavity 7 into two spaces, one of which is used to mount the heating body 9 and heat-resistant components, and the other of which is used to mount circuit boards, batteries and other components that are less resistant to heat, so that when the heating body 9 is heated, the heat shield 8 can also have a heat insulation effect of protecting the components in addition to pressing the sealing ring 5.

[0066] The heat shield 8 can have a wiring channel for connecting the two spaces.

[0067] In the overall structure of the cup, the top heat insulation cavity 207, the heat insulation cavity between the outer cup body and the inner cup body, and the installation cavity 7 can be independent of each other. At the junction of the intermediate transition piece 3 and the outer cup mouth 101 and the junction of the intermediate transition piece 3 and the inner cup mouth 201 along the route from the internal cavity to the installation cavity 7, multiple sealing arrangements are provided, so that when the junctions are infiltrated with water, the situation that water flows into the installation cavity 7 is not easy to occur, effectively ensuring the safety of electricity use.

[0068] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the application being defined by the appended claims rather than by the above description, and it is therefore intended that all changes and modifications that come within the meaning and range of equivalency of the claims are resolvable thereunder. Any reference signs in the claims should not be construed as limiting the claims concerned.
