Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cooking equipment, and particularly relates to a container and a liquid heating device. BACKGROUND

[0002] The current liquid heating device usually comprises a base assembly 60a and a container body 10a placed on the base assembly 60a, as shown in the figure. Figure 1 When the temperature of the container body 10a is relatively high, the user is easy to touch the container body 10a and get scalded in the process of holding the handle 20a. SUMMARY

[0003] Therefore, the utility model aims to provide a container and a liquid heating device applying the container, so that the user is not easy to get scalded when taking and placing the container, and the safety is good.

[0004] The first aspect embodiment of the utility model provides a container, which comprises: a container body, the opposite two sides of the container body having connecting parts; a handle, the two ends of the handle being rotationally connected with the corresponding connecting parts; wherein at least one of the two connecting parts is provided with a plurality of stop protrusions distributed in the circumferential direction around the rotation center line of the handle on one of the outer side surface of the handle and the inner side surface of the corresponding end part of the handle, and the other is provided with a limiting protrusion, in the process of rotating the handle, the limiting protrusion can press the stop protrusions in turn in the lateral direction of the stop protrusions, and the limiting protrusion can stay between any two stop protrusions adjacent in the circumferential direction.

[0005] The container provided by the aspect embodiment is rotationally connected with the container body at the two ends of the handle, and the handle can be rotated and stayed at a plurality of positions, instead of being pulled up and placed on one side of the container body, when the user holds the handle, since the handle can be vertically or obliquely erected, the user will not touch the container body, which can effectively avoid the user getting scalded and improve the product use safety. Moreover, since the posture of the handle can be adjusted, when placing the container, the handle can be rotated to a suitable angle according to the use habit of the user and different scenes, which facilitates holding the handle in multiple postures and improves the user experience.

[0006] Specifically, the connecting part and the end of the handle are provided with a plurality of stop protrusions on one of them, and a limiting protrusion on the other, the plurality of stop protrusions are distributed around the rotation center line of the handle, and the limiting protrusion is located between two adjacent stop protrusions. During the rotation of the handle, the user overcomes the limitation of the stop protrusions, passes through and presses the stop protrusions, until the limiting protrusion stays between the two adjacent stop protrusions, and the position of the limiting protrusion is limited by the two stop protrusions, thereby limiting the position of the handle, so that the handle can be stably stopped at the hollow position, the operation is convenient, the flexibility is good, and the user can make the limiting protrusion stay between the appropriate adjacent two stop protrusions according to the needs. The design of the plurality of stop protrusions and the limiting protrusion is simple in structure and convenient to process.

[0007] Moreover, the limiting protrusion presses the stop protrusion from the side of the stop protrusion, compared with the limiting protrusion pressing the stop protrusion from the top of the stop protrusion, the limiting protrusion or the stop protrusion needs to have a certain elasticity, on the one hand, it can reduce the resistance during the rotation of the handle, and the user can rotate the handle more easily, and on the other hand, it can make the stop protrusion and the limiting protrusion have a certain structural strength, and improve the limiting effect.

[0008] In some embodiments, the plurality of stop protrusions are arranged in a single row, and the number of limiting protrusions is one, and the limiting protrusion presses the stop protrusion on the side of the plurality of stop protrusions facing or away from the rotation center line of the handle.

[0009] In these embodiments, the plurality of stop protrusions are arranged in a single row, and the number of limiting protrusions is one, and the structure is simple and convenient to process. During the rotation of the handle, the limiting protrusion presses the stop protrusion on the side of the plurality of stop protrusions facing or away from the rotation center line of the handle, so that the resistance during the rotation of the handle will not be too large, and the user can rotate the handle more easily.

[0010] In some embodiments, the plurality of stop protrusions are arranged in a single row, and the number of limiting protrusions is two, and the two limiting protrusions press the stop protrusion on the two sides of the plurality of stop protrusions facing and away from the rotation center line of the handle respectively.

[0011] In these embodiments, during the rotation of the handle, the single row of stop protrusions moves between the two limiting protrusions, which can limit the up and down movement of the handle, thereby avoiding the limiting protrusion moving away from the stop protrusion and causing the handle to be mistakenly pulled up and laid down. Moreover, during the rotation of the handle, the two limiting protrusions press the stop protrusion at the same time, which increases the rotation resistance of the handle and improves the hand feeling. Moreover, each limiting protrusion can stay and limit between the two stop protrusions, which is conducive to stably maintaining the hollow posture of the handle.

[0012] In some embodiments, the plurality of stop protrusions are arranged in N rows, any two adjacent rows of stop protrusions form a group, and each row of stop protrusions is arranged circumferentially around the rotation center line of the handle; the number of limit protrusions is N-1, each limit protrusion moves between a group of stop protrusions and presses the stop protrusions on both sides, and N is a positive integer greater than or equal to 2.

[0013] In these embodiments, each limit protrusion moves between two rows of stop protrusions during rotation of the handle, which can limit the up-and-down movement of the limit protrusion and thus limit the up-and-down movement of the handle, so that the limit protrusion is prevented from moving away from the stop protrusions and causing the handle to be pulled up and laid down by mistake. Moreover, each limit protrusion presses the stop protrusions on both sides during rotation of the handle, which has a certain rotation resistance, so that when the limit protrusion stays between two adjacent stop protrusions in a row of stop protrusions, it is also limited by the other row of stop protrusions, which is conducive to the stable maintenance of the hollow posture of the handle.

[0014] In some embodiments, the number of limit protrusions is at least two, which are arranged circumferentially around the rotation center line of the handle, and each limit protrusion can press the stop protrusions during rotation of the handle, and all limit protrusions can stay between two adjacent stop protrusions at the same time.

[0015] In these embodiments, at least two limit protrusions press the stop protrusions during rotation of the handle, which increases the rotation resistance and improves the rotation feel of the handle. Moreover, all limit protrusions can be limited between two adjacent stop protrusions at the same time, and the plurality of stop protrusions can limit the at least two limit protrusions at multiple points, which improves the stability of the handle in the hollow state.

[0016] In some embodiments, the number of stop protrusions in each row is greater than or equal to 6. In this way, the handle can stay in at least 5 positions during rotation, which facilitates the rotation of the handle to a suitable angle.

[0017] In some embodiments, the stop protrusions are first protrusions protruding outward from the outer surface of the connecting portion, and the limit protrusions are second protrusions protruding outward from the end surface of the handle. The structure is simple and convenient to process.

[0018] In some embodiments, the plurality of stop protrusions are arranged on the upper half or lower half of the rotation center line of the handle. Since the handle rotates approximately 180°, the plurality of stop protrusions do not need to be arranged in a full circle, which can simplify the structure and save costs.

[0019] In some embodiments, the amount of interference between the limiting protrusion and the stopping protrusion during rotation of the handle is between 0.6mm and 1.2mm. The handle can have a certain resistance during rotation, but not too large, and the rotation feels good, and the handle can be stably stopped in the hollow.

[0020] In some embodiments, a first connecting hole is arranged on the connecting portion, an end of the handle is provided with a second connecting hole, and the container further comprises a handle connecting piece, which passes through the first connecting hole and the second connecting hole respectively, so that the handle can rotate around the handle connecting piece; wherein the plurality of stopping protrusions are distributed circumferentially and spaced apart around the handle connecting piece, and the gap between the part of the handle connecting piece extending into the first connecting hole and the first connecting hole is between 0.1mm and 0.4mm.

[0021] The gap between the part of the handle connecting piece extending into the first connecting hole and the first connecting hole represents the maximum movable amount of the handle connecting piece in the radial direction of the first connecting hole. If the gap between the part of the handle connecting piece extending into the first connecting hole and the first connecting hole is too small, the handle connecting piece is difficult to assemble into the first connecting hole; if the gap between the part of the handle connecting piece extending into the first connecting hole and the first connecting hole is too large, the handle will shake and even cause the stopping protrusions and the limiting protrusions to separate, so that the handle cannot be fixed. Therefore, in these embodiments, the gap between the part of the handle connecting piece extending into the first connecting hole and the first connecting hole is between 0.1mm and 0.4mm, which is convenient for assembly and does not cause the handle to shake greatly.

[0022] In some embodiments, the thickness H of the first connecting hole is between 4.5mm and 5.5mm, and the distance L between the first connecting hole and the top of the connecting portion is between 6.5mm and 7.5mm. The first connecting hole has a certain structural strength, which is beneficial to make the container bear more than 8kg.

[0023] In some embodiments, the handle connecting piece comprises a connecting shaft and a stop portion at both ends of the connecting shaft, the connecting shaft extends into the first connecting hole and the second connecting hole, and the connecting portion and the end of the handle are limited between the two stop portions. The handle can be prevented from easily separating from the container body.

[0024] In some embodiments, the top of the container body has a connecting lug protruding upward, and the connecting lug is configured as the connecting portion. In this way, there is no need to punch holes in the main body part of the container body, which can avoid water leakage and ensure the structural strength of the main body part of the container body.

[0025] In some embodiments, a part of the side wall of the container body is configured as the connecting portion. The protruding connecting lug structure can be avoided, and the material can be reduced to save costs.

[0026] In some embodiments, the handle is a high-temperature-resistant polypropylene handle. It is safe and harmless, has good high-temperature resistance, is not easy to scald the user, has high mechanical strength, good electrical insulation, and light weight.

[0027] The second aspect of the utility model provides a kind of liquid heating device, and the liquid heating device includes the container and heating piece of any one of the above embodiments, and heating piece is used to heat the liquid in container.

[0052] The embodiments of the present application will be described below with reference to the accompanying drawings. Figures 2 to 4 The embodiments of the present application will be described below with reference to the accompanying drawings.

[0053] As Figures 2 to 4 The first aspect of the embodiments of the present application provides a container, which comprises: a container body 10, the opposite sides of the container body 10 are provided with connecting portions 110; a handle 20, the two ends of the handle 20 are respectively rotationally connected with the corresponding connecting portions 110; wherein at least one of the two connecting portions 110 is provided with a plurality of stop protrusions 111 which are distributed in the circumferential direction around the rotation center line of the handle 20 on one of the outer side surface of the handle 20 and the inner side surface of the end portion of the corresponding handle 20, and a limiting protrusion 210 is provided on the other one, the limiting protrusion 210 can press the stop protrusions 111 in the lateral direction in sequence during the rotation of the handle 20, and the limiting protrusion 210 can stay between any two circumferentially adjacent stop protrusions 111.

[0054] The container provided by the embodiment of the present aspect is rotatably connected at both ends of the handle 20 with the container body 10, and the handle 20 can be rotated and stopped at multiple positions, rather than being pulled to be placed on one side of the container body 10. When a user holds the handle 20, the user will not touch the container body 10 because the handle 20 can be vertically or obliquely erected, which can effectively avoid the user from being scalded and improve the product use safety. Moreover, the posture of the handle 20 can be adjusted, and when the container is placed, the handle 20 can be rotated to a suitable angle according to the user's use habit and different scenes, which facilitates the user to hold the handle 20 in multiple postures and improves the user experience.

[0055] Specifically, one of the connecting part 110 and the end of the handle 20 is provided with multiple stop protrusions 111, and the other is provided with a limiting protrusion 210. The multiple stop protrusions 111 are circumferentially spaced around the rotation center line of the handle 20. During the rotation of the handle 20, the user overcomes the limitation of the stop protrusions 111, passes through and extrudes the stop protrusions 111, until the limiting protrusion 210 is stopped between two circumferentially adjacent stop protrusions 111, and the position of the limiting protrusion 210 is limited by the two stop protrusions 111, thereby limiting the position of the handle 20, so that the handle 20 can be stably stopped at the hollow position, which is convenient to operate and has good flexibility. The user can stop the limiting protrusion 210 between the appropriate adjacent two stop protrusions 111 according to the need. The design of the multiple stop protrusions 111 and the limiting protrusion 210 is simple in structure and convenient to process.

[0056] It is worth noting that the rotation center line of the handle 20 refers to the center line around which the handle 20 rotates during rotation. In the case that the handle 20 is rotatably connected to the connecting part 110 through the connecting shaft 310, the rotation center line of the handle 20 can be the axis of the connecting shaft 310.

[0057] Moreover, the limiting protrusion 210 extrudes the stop protrusion 111 from the side of the stop protrusion 111, and the limiting protrusion 210 extrudes the stop protrusion 111 from the top of the stop protrusion 111. Compared with the case that the limiting protrusion 210 or the stop protrusion 111 needs to have a certain elasticity, on the one hand, the resistance during the rotation of the handle 20 can be reduced, which facilitates the user to rotate the handle 20 more easily, and on the other hand, the stop protrusion 111 and the limiting protrusion 210 can have a certain structural strength, thereby improving the limiting effect.

[0058] Among them, the corresponding limiting protrusion 210 and multiple stop protrusions 111 can be arranged only on one connecting part 110 and the end of the handle 20 corresponding thereto, which simplifies the structure and facilitates the processing. The limiting and stopping structure described above can also be arranged on both connecting parts 110 and the two ends of the handle 20, thereby improving the stability of the handle 20 when being rotated and stopped in the air.

[0059] Alternatively, multiple stop protrusions 111 can be provided on the connecting part 110, and a limiting protrusion 210 can be provided at the end of the handle 20. In this way, when rotating the handle 20, only one limiting protrusion 210 needs to be moved to pass through and press the multiple stop protrusions 111 in sequence, making it easier to rotate the handle 20 and more convenient to operate. Of course, a limiting protrusion 210 can also be provided on the connecting part 110, and multiple stop protrusions 111 can be provided at the end of the handle 20. In this way, when rotating the handle 20, multiple stop protrusions 111 can be rotated simultaneously, passing through and pressing the limiting protrusions 210 in sequence.

[0060] Furthermore, in related technologies, such as Figure 1 As shown, the container body 10a is placed on the base assembly 60a. Since the handle 20a is fixed to the side wall of the container body 10a, when placing the container body 10a, the handle 20a can only be placed facing outwards for easy retrieval later, which restricts the placement posture of the container body 10a. However, in this embodiment, since the handle 20a can rotate and stop above the container body 10, there is no need to overly consider the orientation of the handle 20a when placing the container body 10. The handle 20a can be rotated to a suitable position when retrieving the container body 10 later, facilitating container storage. Furthermore, when storing, the handle 20a can be rotated to fit snugly against the container body 10, or roughly flipped to a horizontal position, saving storage space.

[0061] Regarding the specific placement of the stop protrusion 111 and the limiting protrusion 210, in some embodiments, the multiple stop protrusions 111 are arranged in a single row, and the number of limiting protrusions 210 is one. The limiting protrusion 210 presses against the stop protrusions 111 on the side of the multiple stop protrusions 111 facing or away from the rotation center line of the handle 20.

[0062] In these embodiments, the multiple stop protrusions 111 are arranged in a single row, and the number of limiting protrusions 210 is one, resulting in a simple structure and convenient manufacturing. When the handle 20 is rotated, the limiting protrusion 210 presses against the stop protrusions 111 from one side toward the rotation center line of the handle 20 or away from the rotation center line of the handle 20, which can prevent excessive resistance during the rotation of the handle 20, making it easier for the user to rotate the handle 20.

[0063] Specifically, when the limiting protrusion 210 rotates between the two stop protrusions 111, the stop protrusions 111 located at the upper left and upper right of the limiting protrusion 210 can limit the limiting protrusion 210, or the stop protrusions 111 located at the lower left and lower right of the limiting protrusion 210 can limit the limiting protrusion 210, thereby restricting the rotation of the limiting protrusion 210 and thus restricting the rotation of the handle 20.

[0064] In other embodiments, the plurality of stop protrusions 111 are arranged in a single row, and the number of limiting protrusions 210 is two, one of which presses against the stop protrusions 111 on the side of the plurality of stop protrusions 111 facing the rotation center line of the handle, and the other limiting protrusion 210 presses against the stop protrusions 111 on the side of the plurality of stop protrusions 111 away from the rotation center line of the handle.

[0065] In these embodiments, during the rotation of the handle 20, the single row of stop protrusions 111 moves between the two limiting protrusions 210, which can restrict the vertical movement of the handle 20, thereby preventing the limiting protrusions 210 from moving away from the stop protrusions 111 and causing the handle 20 to be accidentally pulled down. Moreover, during the rotation of the handle 20, the two limiting protrusions 210 simultaneously compress the stop protrusions 111, increasing the rotational resistance of the handle 20 and improving the feel. Furthermore, each limiting protrusion 210 can stop and be limited between the two stop protrusions 111, which helps the handle 20 to maintain a stable hollow posture.

[0066] In other embodiments, the multiple stop protrusions 111 are arranged in N rows, with any two adjacent rows of stop protrusions 111 forming a group. Each row of stop protrusions 111 is circumferentially spaced around the rotation center line of the handle 20. The number of limiting protrusions 210 is N-1, and each limiting protrusion 210 moves between a group of stop protrusions 111 and presses against the stop protrusions 111 on both sides. N is a positive integer greater than or equal to 2.

[0067] In these embodiments, during the rotation of the handle 20, each limiting protrusion 210 moves between two rows of stop protrusions 111. These two rows of stop protrusions 111 restrict the vertical movement of the limiting protrusion 210, thereby limiting the vertical movement of the handle 20 and preventing the limiting protrusion 210 from moving away from the stop protrusions 111, which could cause the handle 20 to be accidentally pulled down. Moreover, when the handle 20 is rotated, each limiting protrusion 210 simultaneously compresses the stop protrusions 111 on both sides, providing a certain rotational resistance. Thus, when the limiting protrusion 210 stops between two adjacent stop protrusions 111 in a row of stop protrusions 111, it is also simultaneously limited by the other row of stop protrusions 111, which helps the handle 20 maintain a stable hollow posture.

[0068] As an example, such as Figure 3 and Figure 4 As shown, multiple stop protrusions 111 are arranged in two rows, and there is one limiting protrusion 210. The limiting protrusion 210 moves between the two rows of stop protrusions 111 and squeezes the stop protrusions 111 on both sides.

[0069] As an example, the plurality of stop protrusions 111 are arranged in three rows, and the number of the limiting protrusions 210 is two, and the two limiting protrusions 210 are respectively inserted between the corresponding two rows of stop protrusions 111.

[0070] In some other embodiments, the number of the limiting protrusions 210 is at least two, and the limiting protrusions 210 are circumferentially spaced around the rotation center line of the handle 20, and each limiting protrusion 210 can extrude the stop protrusion 111 during the rotation of the handle 20, and all the limiting protrusions 210 can simultaneously stay between the adjacent two stop protrusions 111 at the position of the limiting protrusions 210.

[0071] In these embodiments, at least two limiting protrusions 210 extrude the plurality of stop protrusions 111 during the rotation of the handle 20, which increases the rotation resistance and improves the rotation feeling of the handle 20. Moreover, all the limiting protrusions 210 can stay between the adjacent two stop protrusions 111 at the position of the limiting protrusions 210, and the plurality of stop protrusions 111 realize multi-point limiting for the at least two limiting protrusions 210, which improves the stability of the handle 20 in the hollow.

[0072] As an example, two limiting protrusions 210 are arranged at each end of the handle 20, and the plurality of stop protrusions 111 are arranged in a single row on the connecting portion 110, and the two limiting protrusions 210 are located on the side of the plurality of stop protrusions 111 away from the rotation center line of the handle 20, and are circumferentially spaced around the rotation center line of the handle 20. The rotation of the handle 20 drives the rotation of the two limiting protrusions 210, and the two limiting protrusions 210 respectively extrude the stop protrusions 111 passed thereby. When the handle 20 rotates to the specified position, the two limiting protrusions 210 are limited between the adjacent two stop protrusions 111 at the position of the limiting protrusions 210, and the whole realizes two-point limiting for the handle 20, which is beneficial to the stable stop of the handle 20 in the hollow.

[0073] As an example, two limiting protrusions 210 are arranged at each end of the handle 20, and the plurality of stop protrusions 111 are arranged in a double row on the connecting portion 110, and the two limiting protrusions 210 are located between the two rows of stop protrusions 111, and are circumferentially spaced around the rotation center line of the handle 20. The rotation of the handle 20 drives the rotation of the two limiting protrusions 210, and the two limiting protrusions 210 respectively extrude the stop protrusions 111 passed thereby. When the handle 20 rotates to the specified position, the adjacent two stop protrusions 111 in each row of stop protrusions 111 limit one of the two limiting protrusions 210, and the other adjacent two stop protrusions 111 limit the other of the two limiting protrusions 210, and the other row of stop protrusions 111 also limits the two limiting protrusions 210, and the whole realizes eight-point limiting for the handle 20, which is beneficial to the stable stop of the handle 20 in the hollow.

[0074] Further, in some embodiments, the number of each row of stop protrusions 111 is greater than or equal to 6. In this way, the handle 20 can be stopped at least at 5 positions during rotation, facilitating rotation of the handle 20 to the appropriate angle.

[0075] In actual applications, the number of each row of stop protrusions 111 can be designed as needed. For example, Figure 4 As shown, the stop protrusions 111 are arranged in two rows, and the number of each row of stop protrusions 111 is 11.

[0076] For the specific structure of the stop protrusions 111 and the limiting protrusions 210, further, in some embodiments, as shown in Figure 3 and Figure 4 The stop protrusions 111 are first protrusions protruding outward from the outer surface of the connecting portion 110, and the limiting protrusions 210 are second protrusions protruding outward from the end surface of the handle 20. The structure is simple and facilitates processing.

[0077] Especially when the stop protrusions 111 are integrally formed with the connecting portion 110, and the limiting protrusions 210 are integrally formed with the handle 20, they are firmly connected and can prevent the stop protrusions 111 and the limiting protrusions 210 from falling off and being damaged during rotation of the handle 20.

[0078] Of course, the stop protrusions 111 and the limiting protrusions 210 can also be structures such as protruding columns.

[0079] Further, in some embodiments, as shown in Figure 4 The plurality of stop protrusions 111 are arranged on the upper half or the lower half of the rotation center line of the handle 20. Since the handle 20 is rotated by approximately 180°, the plurality of stop protrusions 111 do not need to be arranged in a full circle, which can simplify the structure and save costs.

[0080] Further, in some embodiments, the interference amount of the limiting protrusions 210 and the stop protrusions 111 during rotation of the handle 20 is between 0.6 mm and 1.2 mm. This can make the handle 20 have a certain resistance during rotation, but not too large, and the rotation feels good, and can also make the handle 20 can be stably stopped in the hollow.

[0081] It is worth noting that the interference amount here refers to the deformation amount of the limiting protrusions 210 and the stop protrusions 111 during rotation of the handle 20, and one or both of them are pressed flat by 0.6 mm to 1.2 mm, and each other to make the handle 20 continue to rotate.

[0082] Further, in some embodiments, as shown in Figures 2 to 4As shown, the connecting portion 110 is provided with a first connecting hole 112, and the end of the handle 20 is provided with a second connecting hole 220. The container further comprises a handle connecting piece 30, which respectively penetrates the first connecting hole 112 and the second connecting hole 220, so that the handle 20 can rotate around the handle connecting piece 30. A plurality of stop protrusions 111 are circumferentially spaced around the handle connecting piece 30. The gap between the part of the handle connecting piece 30 extending into the first connecting hole 112 and the first connecting hole 112 is 0.1mm to 0.4mm.

[0083] The gap between the part of the handle connecting piece 30 extending into the first connecting hole 112 and the first connecting hole 112 represents the maximum movable amount of the handle connecting piece 30 in the first connecting hole 112 in the radial direction of the first connecting hole 112. If the gap between the part of the handle connecting piece 30 extending into the first connecting hole 112 and the first connecting hole 112 is too small, the handle connecting piece 30 is difficult to assemble into the first connecting hole 112. If the gap between the part of the handle connecting piece 30 extending into the first connecting hole 112 and the first connecting hole 112 is too large, it will cause the handle 20 to shake and even cause the stop protrusions 111 to separate from the limiting protrusions 210, so that the handle 20 cannot be fixed. Therefore, in these embodiments, the gap between the part of the handle connecting piece 30 extending into the first connecting hole 112 and the first connecting hole 112 is between 0.1mm and 0.4mm, which is convenient for assembly and will not cause the handle 20 to shake greatly.

[0084] For example, the gap between the part of the handle connecting piece 30 extending into the first connecting hole 112 and the first connecting hole 112 is 0.2mm or 0.3mm.

[0085] Further, in some embodiments, as shown in Figure 3 The thickness H of the first connecting hole 112 is 4.5mm to 5.5mm, and the distance L between the first connecting hole 112 and the top of the connecting portion 110 is 6.5mm to 7.5mm. The first connecting hole 112 has a certain structural strength, which is beneficial to make the container can bear more than 8kg.

[0086] For example, the thickness H of the first connecting hole 112 is 4.8mm or 5mm or 5.2mm. The distance L between the first connecting hole 112 and the top of the connecting portion 110 is 6.6mm or 7mm or 7.3mm.

[0087] Further, in some embodiments, as shown in Figure 3 The handle connecting piece 30 comprises a connecting shaft 310 and a stop portion 320 located at both ends of the connecting shaft 310. The connecting shaft 310 extends into the first connecting hole 112 and the second connecting hole 220, and the connecting portion 110 and the end of the handle 20 are limited between the two stop portions 320. It can avoid the handle 20 from easily separating from the container body 10.

[0088] Further, in some embodiments, as shown in Figures 2 to 4 the top of the container body 10 has a protruding connecting lug configured as the connecting portion 110. In this way, no hole is needed to be punched in the main body of the container body 10, thus avoiding water leakage and ensuring the structural strength of the main body of the container body 10.

[0089] In other embodiments, a part of the sidewall of the container body 10 is configured as the connecting portion 110. The protruding connecting lug structure can be omitted, thus reducing material usage and saving cost.

[0090] In specific applications, as shown in Figure 2 and Figure 4 when the container cover 40 is closed on the container body 10, the container cover 40 is lower than the first connecting hole 112. On the one hand, water leakage is avoided, and on the other hand, heat is prevented from overflowing onto the handle 20, which helps to reduce the temperature of the handle 20 and avoid user scalding.

[0091] Further, in some embodiments, the handle 20 is a high-temperature-resistant polypropylene handle 20. It is safe and harmless, has good high-temperature resistance, is not easy to scald users, has high mechanical strength, good electrical insulation, and light weight.

[0092] As shown in Figure 2 the second aspect of the utility model provides a kind of liquid heating device, and the liquid heating device includes the container and heating piece of any one of the above embodiments, and the heating piece is used to heat the liquid in container. The liquid heating device provided by the present aspect embodiment has the container of any one of the above embodiments, and further has the beneficial effects of any one of the above embodiments, which will not be repeated here.

[0093] Further, in some embodiments, as shown in Figure 2 the liquid heating device further includes a container cover 40, a heating disc 50 and a base assembly 60. The container cover 40 is closed on the container body 10, the heating disc 50 is arranged at the bottom of the container body 10 and used to heat the liquid in the container body 10, the container body 10 is placed on the base assembly 60, and the base assembly 60 can provide power to the heating disc 50 to control the heating disc 50 to be powered and heated.

[0094] Further, in some embodiments, the container can be a medicine pot, a kettle, a teapot, a health pot, a heat preservation barrel, etc. The liquid heating device can be a medicine pot with a container, an electric kettle, an electric teapot, an electric health pot, an electric heat preservation barrel, etc., which will not be listed one by one.
