[0005] The liner assembly provided by the embodiment of the utility model includes a container body, a heating plate and a container water channel coupler. The heating plate is arranged at the lower end of the container body and blocks the lower end opening of the container body to form the bottom wall of the container body. The structure is simple, and the heating plate can directly heat the liquid in the container body, thereby improving the heating efficiency. The container water channel coupler is arranged at the lower part of the heating plate, so that the liquid in the container body can flow out through the container water channel coupler, and it is convenient to set up a liquid outlet device and other structures to lead out the liquid, which is conducive to realizing the function of automatic water discharge. Among them, the container body is made of glass, and the glass container body has the advantages of not easy to precipitate harmful substances at high temperature, high safety, and beautiful appearance, and is suitable for holding high-temperature liquids. Moreover, the glass container body does not need to be made into a double-layer structure, and the structure is simpler and easier to process and produce. Compared with the double-layer structure of the inner stainless steel liner and the outer shell used in the related art, the processing technology is simpler, and the sealing structure set between the double-layer structures is also omitted, which simplifies the structure of the liner assembly, reduces the parts, and simplifies the assembly process.

[0006] In some embodiments, a step portion protruding inward is provided on the inner side wall of the lower end of the container body, and the heating plate is provided on the upper surface of the step portion to block the opening of the lower end of the container body. In this way, the heating plate can be supported by the step portion, and the fixing of the heating plate is more secure, preventing the heating plate from falling downward due to the gravity of the liquid in the container body.

[0007] In some embodiments, a handle is provided on the outer side wall of the upper end of the container body, and the handle is a glass handle, and the handle and the container body are an integrated structure. Providing the handle makes it convenient for the user to pick up and place the container body, and the operation is more convenient. Furthermore, the handle and the container body are provided as an integrated structure, which has good mechanical properties and can improve the connection strength between the handle and the container body. In addition, the handle and the container body can be made into one piece and mass-produced to improve the processing efficiency of the product and reduce the processing cost of the product. In addition, by designing the handle and the container body as an integrated structure, the integrity of the liner assembly is improved, the number of parts is reduced, the installation process is reduced, the installation efficiency is improved, and the installation of the liner assembly is more convenient and reliable.

[0008] In some embodiments, the liner assembly also includes: a handle, which is ring-shaped, and an outwardly protruding flange is provided on the outer wall of the upper end of the container body. The handle cover is provided on the outer wall of the container body and abuts against the lower side of the flange to limit the upward movement of the handle.

[0009] In these embodiments, the handle is ring-shaped and is sleeved on the container body. The flange at the upper end of the container body can stop the handle, thereby preventing the handle from moving upward relative to the container body and then separating from the container body, thereby achieving easy operation by holding the handle to pick up and place the container body.

[0010] In some embodiments, the liner assembly further includes: a protrusion is also provided on the outer side wall of the upper end of the container body, the protrusion is provided below the flange and spaced apart from the flange, and the handle is installed between the flange and the protrusion.

[0011] In these embodiments, the raised portion is provided to limit the downward movement of the handle relative to the container body, thereby preventing the handle from moving downward relative to the container body and then separating from the container body, so that the handle can be restricted between the flange and the raised portion, and the position of the handle on the container body will not change significantly, making it more convenient to pick up or place the container body by holding the handle.

[0012] In some embodiments, the inner ring of the handle is provided with a soft ring body, which can be squeezed and deformed, and the inner diameter of the ring body is less than or equal to the outer diameter of the container body, so that there is an interference fit between the ring body and the container body.

[0013] In these embodiments, the soft ring body can be squeezed and deformed, and the inner diameter of the ring body can be set to be less than or equal to the outer diameter of the container body, so that the ring body can be stretched to a larger size and then mounted on the container body. The ring body and the container body have an interference fit, and the squeezing force between the ring body and the container body will further make the connection between the handle and the container body tighter and more stable, and can further prevent the handle from moving relative to the container body. In addition, the ring body that can be squeezed and deformed is also conducive to the annular handle passing through the protrusion to be installed at the designated position of the container body. Specifically, in the process of installing the handle, the annular handle is mounted on the container body from bottom to top, and the handle will pass through the protrusion. Since the ring body can be squeezed and deformed by the protrusion, the ring body can forcibly pass through the protrusion to achieve the installation of the handle.

[0014] In some embodiments, the handle includes a first semi-ring body and a second semi-ring body, and the first semi-ring body and the second semi-ring body can be enclosed in a ring shape. The first end of the first semi-ring body is rotatably connected to the first end of the second semi-ring body, and the second end of the first semi-ring body is detachably connected to the second end of the second semi-ring body. Rotating the first semi-ring body and / or the second semi-ring body can form a gap between the second end of the first semi-ring body and the second end of the second semi-ring body that is larger than the diameter of the container body, so that the handle cover can be set on the container body.

[0015] In these embodiments, the handle is further designed as a structure that can be opened and closed, so that when the handle needs to be installed, the handle is opened so that the handle can be wrapped around the outer wall of the container body, and then the handle is closed so that the handle is fixed on the outer wall of the container body, thereby achieving the installation of the handle. Among them, the handle includes a first semi-ring body and a second semi-ring body, and the first semi-ring body and the second semi-ring body can be surrounded by a ring shape. The first end of the first semi-ring body is connected to the first end of the second semi-ring body by a structure such as a rotating shaft, so that the two can be rotatably connected. Rotating the first semi-ring body and / or the second semi-ring body can form a gap larger than the diameter of the container body between the second end of the first semi-ring body and the second end of the second semi-ring body, so that the handle can be mounted on the container body; further, the second end of the first semi-ring body and the second end of the second semi-ring body are detachably connected by a connecting structure such as a screw, a bolt, or a snap. After the handle is mounted on the container body, the second end of the first semi-ring body is connected to the second end of the second semi-ring body, so that the handle forms a closed ring, thereby realizing the installation of the handle. When the handle needs to be removed, it can be achieved by opening the detachable connecting structure between the second end of the first semi-ring body and the second end of the second semi-ring body, thereby facilitating the removal of the handle.

[0016] In some embodiments, glue is provided between the heating plate and the inner wall of the container body, and the heating plate and the inner wall of the container body are bonded together by the glue. The glue can not only connect the heating plate and the container body together, but also play a role of sealing and waterproofing, preventing the liquid in the container body from flowing under the heating plate.

[0017] In some embodiments, a sealing ring is sleeved on the outer periphery of the heating plate, and the outer wall of the sealing ring is interference-fitted with the inner wall of the container body to seal the gap between the heating plate and the container body. The interference fit between the sealing ring and the container body can better achieve the sealing between the container body and the heating plate, and the sealing ring has the advantages of simple structure, simple installation process, and low cost.

[0018] In some embodiments, the inner tank assembly also includes: a container base, which is arranged below the heating plate and is detachably connected to the heating plate; a plurality of supporting feet, which are arranged on the lower surface of the container base and are spaced apart along the circumferential direction on the container base to support the container base.

[0019] In these embodiments, a container base is provided below the heating plate, and the container base and the heating plate are connected by fasteners such as screws. The container base can protect the heating plate on the one hand, and can isolate the heat of the heating plate on the other hand to prevent the user from contacting the high-temperature heating plate and getting burned. Furthermore, a plurality of legs are provided on the lower surface of the container base, and the container base is supported by the plurality of legs, which is conducive to maintaining the stability of the container body.

[0020] According to a second aspect of the utility model, the utility model provides an electric thermos, comprising: a main body assembly, wherein a receiving cavity is arranged inside the main body assembly; and an inner liner assembly provided by any embodiment of the first aspect, wherein the inner liner assembly can be detachably installed in the receiving cavity.

[0021] The electric thermos provided by the embodiment of the utility model has all the beneficial effects of the liner assembly provided by any embodiment of the first aspect, which are not listed here one by one. Furthermore, by providing a detachably connected liner assembly and a main body assembly, the liner assembly can be separated from the main body assembly when liquid needs to be poured in, specifically, taken out from the accommodating cavity formed by the main body assembly, so that liquid can be added conveniently, and the liner assembly can be conveniently cleaned without being constrained by the main body assembly.

[0022] In some embodiments, the host component includes: a shell, a accommodating cavity is arranged in the shell, one end of the accommodating cavity has an opening, and the shell also includes a closed installation cavity; a host water channel coupler, arranged on the inner bottom wall of the accommodating cavity, the host water channel coupler is adapted to the container water channel coupler; a liquid outlet component, arranged in the installation cavity, the liquid outlet component is connected to the host water channel coupler, and the liquid outlet component is used to output the liquid in the container body to the outside.

[0023] In these embodiments, the host assembly also includes a host waterway coupler and a liquid outlet assembly for outputting liquid to the outside, and the waterway connection between the liner assembly and the liquid outlet assembly is realized by the cooperation of the container waterway coupler and the host waterway coupler; the liquid outlet assembly usually includes a liquid outlet pipe extending from bottom to top and a liquid outlet nozzle located at the top of the liquid outlet pipe and extending laterally. At this time, the liquid outlet pipe can be arranged in the installation cavity, but in order to facilitate the user to take the liquid, the liquid outlet nozzle needs to be arranged outside the shell, and auxiliary structures such as a liquid taking switch are often required. The weight of the liquid outlet nozzle and the auxiliary structure will cause the center of gravity of the host assembly to move up and tilt forward. After the liner assembly is assembled in the accommodating cavity of the shell, the center of gravity of the whole machine can be moved backward to reduce the risk of tilting forward. The position of the shell is consistent with the liner assembly, so the existence of the shell can move the center of gravity of the host assembly backward, thereby improving the overall structural stability of the host assembly, reducing the risk of the host assembly overturning due to unstable center of gravity after the liner assembly is removed, and ensuring the safety of use. At the same time, by configuring the shell, the inner tank assembly can be concealed, thereby improving the overall appearance of the liquid heating device, facilitating the appearance design of the liquid heating device, and improving design flexibility.

[0052] The following will be combined Figures 2 to 8 The utility model is introduced into an inner tank assembly and an electric water bottle provided in an embodiment.

[0053] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an embodiment of one aspect of the utility model provides an inner liner assembly for an electric thermos, wherein the inner liner assembly includes: a container body 10, the container body 10 is made of glass, and the container body 10 is in a cylindrical shape with openings at both ends; a heating plate 20, the heating plate 20 is arranged at the lower end of the container body 10 and blocks the lower end opening of the container body 10; a container water channel coupler 30, which is arranged at the lower part of the heating plate 20 and is used to connect the container body 10 with the outside.

[0054] The inner tank assembly provided by the embodiment of the utility model has a heating plate 20 arranged at the lower end of the container body 10 and blocks the lower end opening of the container body 10 to form the bottom wall of the container body 10, which has a simple structure, and the heating plate 20 can directly heat the liquid in the container body 10, thereby improving the heating efficiency; the container water channel coupler 30 is arranged at the lower part of the heating plate 20, so that the liquid in the container body 10 can flow out through the container water channel coupler 30, and it is convenient to set up a liquid outlet device and other structures to lead out the liquid, which is conducive to realizing the function of automatic water outlet. Among them, the container body 10 is made of glass, and the glass container body has the advantages of not easy to precipitate harmful substances at high temperature, high safety, and beautiful appearance, and is suitable for holding high-temperature liquids; and the glass container body does not need to be made into a double-layer structure, the structure is simpler, and it is easier to process and produce. Compared with the double-layer structure of the inner stainless steel inner tank 11' and the outer shell 12' used in the related art, the processing technology is simpler, and the sealing structure 13' arranged between the double-layer structure is also omitted, which simplifies the structure of the inner tank assembly, reduces the parts, and simplifies the assembly process.

[0055] Furthermore, in some embodiments, Figure 2 As shown, the wall thickness D of the container body 10 is 5 mm to 10 mm. Within this range, the container body 10 can be guaranteed to have sufficient structural strength, and the container body 10 will not be too heavy and difficult to carry due to the excessive thickness of the wall D. Further, the wall thickness D of the container body 10 is preferably 7 mm to 8 mm. In some embodiments, as Figure 2 As shown, a step portion 110 protruding inward is provided on the inner side wall of the lower end of the container body 10, and the heating plate 20 is provided on the upper surface of the step portion 110 to block the opening of the lower end of the container body 10. In this way, the heating plate 20 can be supported by the step portion 110, and the heating plate 20 is fixed more firmly, preventing the heating plate 20 from falling downward due to the gravity of the liquid in the container body 10.

[0056] In the first embodiment of the present application, Figure 2 and Figure 3As shown, a handle 120 is provided on the outer side wall of the upper end of the container body 10, and the handle 120 is a glass handle 120, and the handle 120 and the container body 10 are an integrated structure. The handle 120 is provided to facilitate the user to pick up and place the container body 10, and the operation is more convenient. Furthermore, the handle 120 and the container body 10 are provided as an integrated structure, which has good mechanical properties and can improve the connection strength between the handle 120 and the container body 10. In addition, the handle 120 and the container body 10 can be made into one piece and mass-produced to improve the processing efficiency of the product and reduce the processing cost of the product. In addition, by designing the handle 120 and the container body 10 as an integrated structure, the integrity of the liner assembly is improved, the number of parts is reduced, the installation process is reduced, the installation efficiency is improved, and the installation of the liner assembly is more convenient and reliable.

[0057] In the second embodiment of the present application, the structure of the handle 120 is different from that of the first embodiment. Figure 4 and Figure 5 As shown, the liner assembly includes a container body 10 and a handle 120. The handle 120 is ring-shaped. An outwardly protruding flange 130 is provided on the outer wall of the upper end of the container body 10. The handle 120 is sleeved on the outer wall of the container body 10 and abuts against the lower side of the flange 130 to limit the upward movement of the handle 120.

[0058] In these embodiments, the handle 120 is ring-shaped and is sleeved on the container body 10. The flange 130 at the upper end of the container body 10 can stop the handle 120, thereby preventing the handle 120 from moving upward relative to the container body 10 and then separating from the container body 10, thereby realizing the container body 10 being picked up and placed by holding the handle 120, which is convenient for operation.

[0059] In some embodiments, Figure 4 and Figure 5 As shown, the liner assembly also includes: a protrusion 140 is also provided on the outer side wall of the upper end of the container body 10, the protrusion 140 is arranged below the flange 130 and spaced apart from the flange 130, and the handle 120 is installed between the flange 130 and the protrusion 140.

[0060] In these embodiments, the raised portion 140 is provided to limit the downward movement of the handle 120 relative to the container body 10, thereby preventing the handle 120 from moving downward relative to the container body 10 and then separating from the container body 10, so that the handle 120 can be restricted between the flange 130 and the raised portion 140, and the position of the handle 120 on the container body 10 will not change significantly, making it more convenient to pick up or place the container body 10 by holding the handle 120.

[0061] In some embodiments, Figure 4 and Figure 5As shown, the inner ring of the handle 120 is provided with a soft ring body 121 , which can be squeezed and deformed, and the inner diameter of the ring body 121 is less than or equal to the outer diameter of the container body 10 , so that the ring body 121 and the container body 10 have an interference fit.

[0062] In these embodiments, the soft ring body 121 can be squeezed and deformed, and the inner diameter of the ring body 121 can be set to be less than or equal to the outer diameter of the container body 10, so that the ring body 121 can be stretched and then sleeved on the container body 10, and the ring body 121 and the container body 10 have an interference fit. The squeezing force between the ring body 121 and the container body 10 will further make the connection between the handle 120 and the container body 10 more compact and stable, and can further prevent the handle 120 from moving relative to the container body 10. In addition, the ring body 121 that can be squeezed and deformed is also conducive to the annular handle 120 passing through the protrusion 140 to be installed at the designated position of the container body 10. Specifically, in the process of installing the handle 120, the annular handle 120 is sleeved on the container body 10 from bottom to top, and the handle 120 will pass through the protrusion 140. Since the ring body 121 can be squeezed and deformed by the protrusion 140, the ring body 121 can forcibly pass through the protrusion 140 to achieve the installation of the handle 120.

[0063] In the third embodiment of the present application, Figure 6 As shown, compared with the second embodiment, the structure of the handle 120 is further improved so that the handle 120 can be switched between an open state and a closed state. The handle 120 includes a first semi-ring body 122 and a second semi-ring body 123. The first semi-ring body 122 and the second semi-ring body 123 can be surrounded by a ring shape. The first end of the first semi-ring body 122 is rotatably connected to the first end of the second semi-ring body 123, and the second end of the first semi-ring body 122 is detachably connected to the second end of the second semi-ring body 123. Rotating the first semi-ring body 122 and / or the second semi-ring body 123 can form a gap larger than the diameter of the container body 10 between the second end of the first semi-ring body 122 and the second end of the second semi-ring body 123, so that the handle 120 can be sleeved on the container body 10.

[0064] In these embodiments, the handle 120 is further designed as a structure that can be opened and closed, so that when the handle 120 needs to be installed, the handle 120 is opened so that the handle 120 can be covered on the outer wall of the container body 10, and then the handle 120 is closed so that the handle 120 is fixed on the outer wall of the container body 10 to achieve the installation of the handle 120. The handle 120 includes a first semi-ring body 122 and a second semi-ring body 123, and the first semi-ring body 122 and the second semi-ring body 123 can be surrounded by a ring shape. The first end of the first semi-ring body 122 and the first end of the second semi-ring body 123 are connected by a rotating shaft 124 and other structures so that the two can be rotatably connected. Rotating the first semi-ring body 122 and / or the second semi-ring body 123 can form a gap larger than the diameter of the container body 10 between the second end of the first semi-ring body 122 and the second end of the second semi-ring body 123, so that the handle 120 can be sleeved on the container body 10; further The second end of the first semi-ring body 122 is detachably connected to the second end of the second semi-ring body 123 by means of a connecting structure such as screws, bolts, and snaps. After the handle 120 is sleeved on the container body 10, the second end of the first semi-ring body 122 is connected to the second end of the second semi-ring body 123, so that the handle 120 forms a closed ring, thereby realizing the installation of the handle 120. In the case where the handle 120 needs to be removed, it can be achieved by opening the detachable connecting structure between the second end of the first semi-ring body 122 and the second end of the second semi-ring body 123, thereby facilitating the removal of the handle 120.

[0065] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, with regard to the specific structure of the handle 120, optionally, the handle 120 includes at least two protrusions protruding outward, so as to facilitate the user to hold the container body 10 with both hands, thereby ensuring the stability of the operation.

[0066] For the sealing structure 13 between the heating plate 20 and the container body 10, as shown in FIG. Figure 7 As shown, in some embodiments, glue 40 is provided between the heating plate 20 and the inner wall of the container body 10, and the heating plate 20 and the inner wall of the container body 10 are bonded and connected by the glue 40. The glue 40 can not only connect the heating plate 20 and the container body 10 together, but also play a role of sealing and waterproofing, preventing the liquid in the container body 10 from flowing under the heating plate 20.

[0067] For the sealing structure 13 between the heating plate 20 and the container body 10, as shown in FIG.

[0070] According to a second aspect of the utility model, the utility model provides an electric thermos, comprising: a main body assembly, wherein a receiving cavity is arranged inside the main body assembly; and an inner liner assembly provided by any embodiment of the first aspect, wherein the inner liner assembly can be detachably installed in the receiving cavity.

[0071] The electric water bottle provided in the embodiment of the utility model has all the beneficial effects of the inner tank assembly provided in any embodiment of the first aspect, which are not listed one by one here.

[0072] Furthermore, by providing a detachably connected liner assembly and a main body assembly, the liner assembly can be separated from the main body assembly when liquid needs to be poured in, specifically, taken out from the accommodating cavity formed by the main body assembly, so that liquid can be added conveniently, and the liner assembly can be conveniently cleaned without being constrained by the main body assembly.

[0073] In some embodiments, the host component includes: a shell, a accommodating cavity is arranged in the shell, one end of the accommodating cavity has an opening, and the shell also includes a closed installation cavity; a host water channel coupler, which is arranged on the inner bottom wall of the accommodating cavity, and the host water channel coupler is adapted to the container water channel coupler 30; a liquid outlet component, which is arranged in the installation cavity, the liquid outlet component is connected to the host water channel coupler, and the liquid outlet component is used to output the liquid in the container body 10 to the outside.

[0074] In these embodiments, the host assembly also includes a host waterway coupler and a liquid outlet assembly for outputting liquid to the outside. The waterway connection between the liner assembly and the liquid outlet assembly is realized by the cooperation of the container waterway coupler 30 and the host waterway coupler; the liquid outlet assembly usually includes a liquid outlet pipe extending from bottom to top and a liquid outlet nozzle located at the top of the liquid outlet pipe and extending laterally. At this time, the liquid outlet pipe can be arranged in the installation cavity, but in order to facilitate the user to take the liquid, the liquid outlet nozzle needs to be arranged outside the shell, and auxiliary structures such as a liquid taking switch are often required. The weight of the liquid outlet nozzle and the auxiliary structure will cause the center of gravity of the host assembly to move up and tilt forward. After the liner assembly is assembled in the accommodating cavity of the shell, the center of gravity of the whole machine can be moved backward to reduce the risk of tilting forward. The position of the shell is consistent with the liner assembly, so the existence of the shell can move the center of gravity of the host assembly backward, thereby improving the overall structural stability of the host assembly, reducing the risk of the host assembly overturning due to unstable center of gravity after the liner assembly is removed, and ensuring the safety of use. At the same time, by configuring the shell, the inner tank assembly can be concealed, thereby improving the overall appearance of the liquid heating device, facilitating the appearance design of the liquid heating device, and improving design flexibility.

[0075] Furthermore, in some embodiments, the host assembly also includes: a host electrical connection coupler, which is arranged on the inner bottom wall of the accommodating cavity, and a container electrical connection coupler adapted to the host electrical connection coupler is arranged on the container body 10; a power supply, which is arranged in the installation cavity, and the power supply is electrically connected to the host electrical connection coupler, and the inner tank assembly is connected to electricity through the cooperation of the container electrical connection coupler and the host electrical connection coupler. Further, in some embodiments, the container electrical connection coupler and the container waterway coupler 30 can be integrated into a container water-electricity integrated coupler, and the host electrical connection coupler and the host waterway coupler can be integrated into a host water-electricity integrated coupler. By configuring the adapted container water-electricity integrated coupler and the host water-electricity integrated coupler, the detachable connection of the liquid circuit and the circuit can be combined into one, which can save material costs. Moreover, this integrated structure only requires single-point positioning, which reduces assembly requirements, thereby further reducing the difficulty of assembly positioning, improving the convenience of assembly operations, fully increasing the possibility of placing the container assembly in place at one time, and reducing the possibility of repeated disassembly and assembly, thereby reducing the risk of liquid dripping or spilling, helping to ensure safe use, and can reduce the user's physical exertion and improve the practicality of the product.
