Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, and in particular to an electric thermos cup. Background Technology

[0002] Using a thermos to brew tea keeps the water at a constant temperature, allowing users to enjoy hot tea anytime. However, most thermoses designed for brewing tea have a tea strainer attached to the rim. With this type of thermos, the water level must completely cover the strainer for the tea leaves to be extracted. If not consumed promptly, the tea will become very strong, affecting the taste. Furthermore, since the thermos is always full of tea, users need to use a separate thermos if they want hot water, which is very inconvenient when traveling or outdoors. A Chinese utility model patent with application number 202020302354.2 and titled "A Novel Tea-Water Separation Suction Spout Vacuum Insulated Cup" discloses the following technical solution: A main cap is screwed to the top of the cup body. The lower end of the main cap is a soaking chamber, and the upper end is screwed to a water-absorbing cover. A groove is provided on the outer wall of the main cap along its height direction, and a through hole communicating with the soaking chamber is opened at the top of the groove. A straw extending to the bottom of the cup body is inserted into the groove. A water-absorbing tube is inserted into the soaking chamber at the bottom of the water-absorbing cover. A concave cavity is provided inside the water-absorbing cover, and a water-absorbing spout is rotatably provided in the concave cavity. When the water-absorbing spout is in a vertical state, it is connected to the water-absorbing tube. When the water-absorbing spout is rotated to a horizontal state, it blocks the water-absorbing tube and hides it in the water-absorbing cover. In this way, tea leaves are placed in the soaking chamber, and hot water from the cup body is brought into the soaking chamber by sucking the water-absorbing spout to soak the tea leaves. The tea is then drunk through the water-absorbing spout. However, this thermos has the following technical problems when used: First, the straw is placed in a groove on the outer wall of the main lid. When water in the cup enters the steeping chamber through the straw, the water flows down the inner wall of the main lid to the bottom of the steeping chamber. The tea leaves initially float on the water and take a long time to steep, so users have to wait a long time to drink the tea.

[0003] Secondly, when using this thermos, the spout needs to be rotated to a vertical position to draw in tea, and then rotated to a horizontal position to block the suction tube and hide it in the suction lid. This requires frequent rotation of the spout, causing it to wear down and loosen easily, reducing the seal between the spout and the suction tube and making it difficult to draw in tea. Furthermore, over time, the rotating part of the spout may become stuck due to material aging, preventing the spout from smoothly switching between vertical and horizontal positions. Additionally, the gap between the spout and the concave cavity is very small, making it difficult to clean thoroughly. Over time, bacteria can easily grow in this area, potentially affecting human health.

[0004] In addition, both the main cover and the absorbent top cover require threaded connections, which must be turned with both hands during operation. Therefore, they are not suitable for one-handed operation and are not very convenient.

[0005] Given the above-mentioned shortcomings of the existing technology, the applicant believes it is necessary to make technical improvements to provide a vehicle-mounted electric thermos cup. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned problems and shortcomings, and to provide a car-mounted electric thermos cup. By setting the lower straw in the tea-making inner liner, water in the thermos cup can be sprayed into the tea-making inner liner along the circumference of the upper opening of the lower straw, which speeds up the tea steeping and shortens the user's waiting time. The upper straw is directly inserted into the spout cap, which is not easy to wear and is easy to clean, thus improving hygiene. In addition, the locking structure allows the tea-making inner liner and spout cap to be fastened to or removed from the thermos cup with one hand, making it more convenient to use. When not drinking water, the upper straw can be placed in the straw slot on the handle, which eliminates the worry of losing the upper straw and ensures its cleanliness. It also makes it easy to put the cup lid back on the spout cap, covering the spout cap and ensuring sealing and heat preservation.

[0007] The technical solution of this utility model is implemented as follows: a car-mounted electric thermos cup includes a thermos cup body with a water outlet assembly and an electric heating base respectively provided at the top and bottom, a cup lid placed above the water outlet assembly, and a handle provided on one side of the thermos cup body; characterized in that: the water outlet assembly includes: a tea liner inserted into the mouth of the thermos cup body, a lower straw inserted into the bottom of the thermos cup body from the upper end of the tea liner, a water outlet cap placed above the tea liner, and an upper straw inserted into the bottom of the tea liner from the top of the water outlet cap; a locking structure is provided between the water outlet cap and the thermos cup body, the water outlet cap is fastened to the thermos cup body through the locking structure and at the same time locks the water liner to the thermos cup body; the handle is provided with a straw slot arranged along its height direction.

[0008] Furthermore, the locking structure includes a retaining ring disposed at the top of the thermos body and two locking assemblies symmetrically disposed on both sides of the water outlet cover; the water outlet cover is fastened to the thermos body by the locking assemblies and the retaining ring locking together.

[0009] Furthermore, the locking assembly includes an unlocking block embedded in the top surface of the water outlet cover, a transverse arm disposed at the bottom end of the unlocking block and arranged transversely along the inner top wall of the water outlet cover, a vertical arm integrally connected to the transverse arm and arranged vertically along the inner wall of the water outlet cover, and a locking tooth disposed at the bottom end of the vertical arm and concealed inside the water outlet cover; a reset spring is also provided between the unlocking block and the water outlet cover.

[0010] Furthermore, the top of the tea liner is provided with a reverse edge that is positioned at the mouth of the thermos body; the reverse edge is locked between the water outlet cap and the thermos body.

[0011] Furthermore, it also includes a tea canister located at the bottom of the electric heating base; the top of the tea canister is screwed onto and concealed at the bottom of the electric heating base.

[0012] Furthermore, the tea canister includes a canister body screwed to the bottom of the electric heating base, a lid placed on the top of the canister body, and a sliding cover plate slidably connected to the top surface of the lid; the lid body is provided with tea holes, and the sliding cover plate can close or open the tea holes.

[0013] Furthermore, the cover has two parallel strip-shaped slots, and a limiting vertical plate is provided at the bottom of the cover along the circumference of the strip-shaped slots; correspondingly, two parallel sliding plates are provided on the sliding cover, and a transverse protrusion is provided at the bottom of the sliding plate that is embedded in the bottom of the limiting vertical plate; the sliding cover is closed or opened by the sliding plates being inserted into the strip-shaped slots and sliding back and forth along the strip-shaped slots.

[0014] Furthermore, a sliding groove is provided on the cover body located between the two strip-shaped slots; an arc-shaped protrusion is provided on the sliding cover plate located between the two sliding insert plates, which can slide back and forth in the sliding groove; positioning protrusions are provided at the front and rear ends of the sliding groove respectively; positioning slots for fixing the arc-shaped protrusions are formed between the positioning protrusions and the front and rear side walls of the sliding groove respectively.

[0015] Furthermore, the insulated cup body includes an insulated inner liner, an extension cover disposed at the bottom of the insulated inner liner, and a protective shell fitted over the outer side of the insulated inner liner and the extension cover; the electric heating base includes a lower control part and an upper heating part embedded in the extension cover; the connection between the lower control part and the upper heating part forms an inserting annular groove, and the bottom of the extension cover and the bottom of the protective shell are respectively inserted into the inserting annular groove so that the insulated cup body and the electric heating base are assembled together.

[0016] Furthermore, the straw slot is located on the outer side of the handle, and a through hole begins at the bottom of the straw slot.

[0017] The beneficial effects of this utility model are: First, the lower straw is inserted into the bottom of the thermos from the top of the tea liner. This allows water in the thermos to spray onto the tea leaves along the circumferential direction of the upper opening of the straw, wetting them. As water enters the tea liner, the tea leaves are also fully soaked, thus shortening the user's waiting time and greatly improving the user experience.

[0018] Secondly, the upper straw is a single tube that is inserted directly into the tea container from the spout cap using a pull-in method. This makes the connection between the upper straw and the spout cap easy to clean, ensuring good hygiene, and there is no need to worry about the upper straw not being able to smoothly draw tea from the tea container. When you don't need to drink water, you can pull out the upper straw and place it in the straw slot on the handle, making it less likely to be lost and keeping it hygienic. Then, place the cup lid on the spout cap. The cup lid doesn't need to be very high to completely cover the spout cap and connect with the insulated cup body, thus reducing heat loss from the insulated cup body.

[0019] In addition, this utility model has a locking component between the water outlet cap and the thermos body. This eliminates the need for twisting; simply pressing the water outlet cap will lock both the water outlet cap and the tea liner onto the thermos body. The water outlet cap and the tea liner can be quickly opened by pressing the locking component. The operation is very convenient and can be completed with one hand, further enhancing the user experience. Attached Figure Description

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0035] like Figures 1 to 4 As shown, this utility model provides a car-mounted electric thermos cup, including a thermos cup body 1 with a water outlet assembly 2 and an electric heating base 3 respectively provided at the top and bottom, a cup lid 4 placed above the water outlet assembly 2, and a handle 5 provided on one side of the thermos cup body 1; in order to achieve the purpose of this utility model: the water outlet assembly 2 includes: a tea water liner 21 inserted into the mouth of the thermos cup body 1, a lower straw 23 inserted into the bottom of the thermos cup body 1 from the upper end of the tea water liner 21, a water outlet cover 22 placed above the tea water liner 21, and an upper straw 24 inserted into the bottom of the tea water liner 21 from the top of the water outlet cover 22; a locking structure 7 is provided between the water outlet cover 22 and the thermos cup body 1, and the water outlet cover 22 is fastened to the thermos cup body 1 by the locking structure 7 and at the same time locks the water liner 21 to the thermos cup body 1; the handle 5 is provided with a straw slot 51 arranged along its height direction.

[0036] In use, the user first pours hot water into the thermos body 1, then places tea leaves into the tea liner 21 and inserts the tea liner 21 into the thermos body 1. Next, the user places the spout cap 22 on top of the tea liner 21 and presses it down. The locking mechanism 7 then locks the entire spout assembly 2 onto the thermos body 1. When the user wants to drink tea, they hold the top of the upper straw 24 in their mouth and inhale, causing the air pressure in the tea liner 21 to be lower than the air pressure in the thermos body 1. Under this pressure difference, the hot water in the thermos body 1 flows through the lower straw 23 into the tea liner 21. The hot water sprays in an umbrella-like pattern along the circumference of the lower straw 23 onto the tea leaves, wetting them. In this way, the tea liner 21 is quickly steeped while water is entering, allowing the user to drink tea immediately without a long wait. The user can also remove the spout assembly 2 and drink the hot water directly from the thermos body 1, offering greater flexibility.

[0037] The upper straw 24 is a single tube inserted into the water outlet cover 22. When not in use, the user can remove it and place it in the straw slot 51 on the handle 5, preventing the upper straw 24 from being lost or soiled. This prevents the upper straw 24 from bending, thus reducing its risk of damage. Furthermore, the straw hole on the water outlet cover 22 can be thoroughly cleaned with a straw brush, eliminating hard-to-reach areas and ensuring good hygiene. The cup lid 4 is made to the standard size of a thermos lid, completely covering the water outlet component 2, resulting in a well-balanced distribution of the thermos's components.

[0038] To ensure the airtightness of the electric thermos, such as Figure 4 , Figure 5 , Figure 7 As shown, sealing rings 25 are provided at the connection between the tea inner liner 21 and the lower straw 23, and at the connection between the spout cap 22 and the upper straw 24. A sealing gasket 221 is provided at the bottom of the spout cap 22 to form a sealing structure with the tea inner liner 21. The sealing gasket 221 is placed on top of the tea inner liner 21, and a through hole is also provided on the sealing gasket 221 for the upper straw 24 to pass through. In this way, when the upper straw 24 passes through the sealing gasket 221, the elastic deformation of the sealing gasket 221 material itself will naturally form a sealing structure between the two.

[0039] In order to enable the locking structure 7 to lock the water outlet cap 22 to the thermos cup body 1 together, as follows: Figures 2 to 5 as well as Figure 9 As shown, the locking structure 7 includes a retaining ring 71 located at the top of the thermos body 1 and two locking components 72 symmetrically arranged on both sides of the water outlet cover 22. The water outlet cover 22 is fastened to the thermos body 1 by the locking components 72 and the retaining ring 71. In this way, the water outlet cover 22 can be easily opened by pressing both locking components 72 simultaneously with one hand.

[0040] The specific structure of the locking assembly 72 is as follows: Figure 5 , Figure 7 , Figure 8As shown, the locking assembly 72 includes an unlocking block 721 embedded in the top surface of the water outlet cover 22, a transverse arm 722 disposed at the bottom end of the unlocking block 721 and arranged transversely along the inner top wall of the water outlet cover 22, a vertical arm 723 integrally connected to the transverse arm 722 and arranged vertically along the inner wall of the water outlet cover 22, and a locking tooth 724 disposed at the bottom end of the vertical arm 723 and hidden inside the water outlet cover 22; a return spring 73 is also provided between the unlocking block 721 and the water outlet cover 22. The entire locking assembly 72 has an L-shaped structure. When the water outlet cap 22 needs to be opened, simply press the unlocking block 721 to move the locking teeth 724 outward and disengage them from the retaining ring 71, thus easily opening the water outlet cap 22. When the water outlet cap 22 is locked onto the thermos cup body 1, the locking teeth 724 engage with the retaining ring 71. At this time, the return spring 73 exerts an outward pushing force on the unlocking block 721, causing the unlocking block 721 to pull the locking teeth 724 against the ring wall of the retaining ring 71, thereby ensuring that the water outlet cap 22 is securely locked onto the thermos cup body 1. Furthermore, during the unlocking and locking process of the water outlet cap 22, the locking assembly 72 only undergoes lateral linear movement, making the operation very time-saving and labor-saving.

[0041] Further as Figure 5 , Figure 7 As shown, in order to prevent the locking assembly 72 from shifting when it is activated, and thus to enable it to function more stably, the water outlet cover 22 is composed of an outer cover shell 222 and an inner cover shell 223 that are fitted together, and the sealing gasket 221 is embedded in the inner cover shell 223. The outer cover 222 has a receiving cavity 2223 at the center of its top surface. A positioning block 224 is embedded in the receiving cavity 2223. A return spring 73 is provided on both sides of the locking positioning block 224. On the top surface of the outer cover 222 located on both sides of the receiving cavity 225, there are unlocking block slots 2221 for the unlocking block 721 to be embedded. The unlocking block 721 is embedded in the unlocking block slot 2221. The bottom of the unlocking block slot 2221 is also provided with a strip hole 2222 for the bottom end of the unlocking block 721 to pass through, and the inner end of the unlocking block 721 is also embedded in the receiving cavity 2223. In this way, when the unlocking block 722 moves, under the combined action of the unlocking block slot 2221, the strip hole 2222 and the receiving cavity 2223, the unlocking block 721 can be limited in all directions (up, down, left, right and front) to effectively prevent the unlocking block 721 from shaking during movement. In order to allow the upper suction tube 24 to pass through, the receiving cavity 225 and the positioning block 224 are respectively provided with through holes for the upper suction tube 24 to pass through.

[0042] like Figure 5 , Figure 8As shown, the bottom end of the unlocking block 721 is provided with a connecting protrusion. During assembly, the connecting protrusion passes through the slot 2222 and connects with the horizontal arm 722. The locking assembly 72 is preferably made of a tough, food-grade plastic material such as PP. The unlocking block 721 and the horizontal arm 722 can be bonded together with food-grade high-temperature resistant silicone. The horizontal arm 722, the vertical arm 723, and the locking teeth 724 can be integrally molded or made separately and bonded together with food-grade high-temperature resistant silicone.

[0043] To prevent the return spring 73 from falling off, such as Figure 5 As shown, the positioning block 224 is provided with a spring hole groove, and the inner end of the unlocking block 721 is provided with a protrusion that is fitted onto the reset spring 73. In this way, both ends of the reset spring 73 are limited and are not easy to fall off.

[0044] Furthermore, to prevent the lateral arm 722 from shifting during movement, such as... Figure 7 , 8 As shown, the top surface of the inner cover 223 is provided with a transverse arm limiting groove 2231, and an arc-shaped clearance groove is provided in the transverse arm limiting groove 2231. The transverse arm 722 is provided with an arc-shaped clearance position 725, thereby forming a hole for the upper straw 24 to pass through. In this way, the transverse arm 722 is hidden in the transverse arm limiting groove 2231, and the top surface of the inner cover 223 and the bottom surface of the outer cover 222 can be tightly fitted together. The two are firmly connected together by food-grade organic silicone, thereby limiting the transverse arm 722 in the left and right and up and down, preventing it from shifting or shaking during movement.

[0045] like Figure 5 , Figure 7 As shown, the vertical arm 723 is disposed between the outer cover shell 222 and the inner cover shell 223, and the locking teeth 724 are disposed below the bottom end of the inner cover shell 223. In this way, when the water outlet cap 22 is fastened onto the thermos cup body 1, the bottom end of the inner cover shell 223 abuts against the outer wall of the cup mouth of the thermos cup body 1, making the contact area between the two larger, thus making the locking more secure.

[0046] Furthermore, in order to make it smoother and easier to attach the water outlet cap 22 to the thermos body 1, the inner cap shell 223 and the outer wall of the thermos body 1 are respectively provided with inclined surfaces that abut against each other, and the retaining ring 71 is located at the bottom of the inclined surfaces.

[0047] In order to ensure that the inner tea container 21 is securely clamped between the spout cap 22 and the thermos body 1, such as Figure 3 , Figure 5As shown, the top of the tea liner 21 is provided with a reverse edge 211 at the mouth of the thermos body 1; the reverse edge 211 is locked between the water outlet cap 22 and the thermos body 1. In this way, when the water outlet cap 22 is fastened to the thermos body 1, the sealing gasket 221 is placed on the reverse edge 211, and the squeezing force generated by the locking structure 7 causes the sealing gasket 221 to elastically deform, thereby firmly locking the reverse edge 211 between the water outlet cap 22 and the thermos body 1, preventing air leakage and water seepage at this point.

[0048] like Figure 1 , Figure 2 As shown, to facilitate convenient access to tea during travel, this utility model also includes a tea canister 6 located at the bottom of the electric heating base 3; the top of the tea canister 6 is screwed and concealed at the bottom of the electric heating base 3. This elevates the electric heating base 3, allowing the tea canister 6 to be placed in the car's cup holder when using the electric thermos in the car, with the electric heating base 3 higher than the cup holder and its power socket also higher. This eliminates the need for bending the power cord to connect the electric thermos to the car's cigarette lighter, preventing internal cord breakage, extending its lifespan, and reducing safety risks. Furthermore, with the top of the tea canister 6 concealed at the bottom of the electric heating base 3, water from the thermos will not spill onto the tea canister 6 when pouring water, preventing the tea leaves inside from becoming damp. The heat generated by the electric heating base 3 also helps keep the tea leaves dry, ensuring tea quality and improving the user experience.

[0049] Furthermore, to facilitate taking tea leaves from tea canister 6, such as Figure 10 As shown, the tea canister 6 includes a canister 61 screwed to the bottom of the electric heating base 3, a lid 62 covering the top of the canister 61, and a sliding cover plate 63 slidably connected to the top surface of the lid 62. The lid 62 has a tea leaf hole 64, and the sliding cover plate 63 can open or close the tea leaf hole 64. The bottom of the electric heating base 3 is correspondingly provided with a receiving cavity 30 for the top of the canister 61 to be concealed, and the top of the canister 61, the lid 62, and the sliding cover plate 63 are concealed in the receiving cavity 30. In this way, when taking out tea, it is not necessary to unscrew the lid 62; simply sliding the sliding cover plate 63 can open the tea leaf hole 64 and pour out the tea, which is very convenient to use. When it is necessary to remove the lid 62 from the can 61, push open the sliding cover 63 to expose the tea leaf hole 64, insert your index or middle finger into the tea leaf hole 64 while your thumb moves the outside of the sliding cover 63 to easily open the lid 62. Conversely, the lid 62 can be installed on the can 61.

[0050] Furthermore, to ensure that the sliding cover 63 slides stably without wobbling from side to side, such as Figure 11 , Figure 12As shown, the cover 62 has two parallel strip-shaped slots 621, and a limiting vertical plate 622 is provided at the bottom of the cover 62 along the circumference of the strip-shaped slots 621; the sliding cover 63 has two parallel sliding inserts 631, and a transverse protrusion 632 is provided at the bottom of the sliding insert 631 that is engaged with the bottom of the limiting vertical plate 622; the sliding cover 63 is closed or opened by the sliding inserts 631 being inserted into the strip-shaped slots 621 and sliding back and forth along the strip-shaped slots 621. In this way, when the sliding cover 63 is slidable, since the sliding inserts 631 are inserted into the strip-shaped slots 621 and the transverse protrusion 632 is engaged with the bottom of the limiting vertical plate 622, the sliding cover 63 will not slip off the cover 62 and will not wobble from side to side during the sliding process, thus enabling the tea hole 64 to be opened or closed very stably.

[0051] Furthermore, in order to smoothly insert the sliding plate 631 into the slotted groove 621, such as... Figure 11 As shown, an insertion groove 624 with a width greater than the transverse protrusion 632 is provided at one end of the strip-shaped groove 621. One side wall of the insertion groove 624 is flush with the wall of the strip-shaped groove 621, while the other side wall extends inward toward the inside of the cover 2. The transverse protrusion 632 faces outward and has an inverted triangular structure at its bottom. The sliding cover plate 63 and the sliding insert plate 631 are usually made of a tough plastic material such as PP in one piece. When the transverse protrusion 632 is inserted into the insertion groove, the transverse protrusion 632 is squeezed inward by the groove wall of the insertion groove 624 and undergoes a slight tilting deformation, which drives the sliding insert plate 631 to be inserted into the insertion groove 624 together. Then, under the action of material elasticity, it returns to a vertical state, and the transverse protrusion 632 is embedded in the bottom of the limiting vertical plate 622.

[0052] Furthermore, to make the sliding cover 63 slide more smoothly, such as Figure 11 As shown, a sliding groove 623 is provided on the cover 62 located between the two strip-shaped slots 621; an arc-shaped protrusion 633 that can slide back and forth in the sliding groove 623 is provided on the sliding cover plate 63 located between the two sliding insert plates 631; positioning protrusions 6231 are respectively provided at the front and rear ends of the sliding groove 623; positioning slots 6232 for fixing the arc-shaped protrusion 633 are respectively formed between the positioning protrusions 6231 and the front and rear side walls of the sliding groove 623. In this way, the resistance of the arc-shaped protrusion 633 when sliding is small, so that the sliding cover plate 63 can slide more smoothly, and the positioning slots 6232 limit the arc-shaped protrusion 633, so that the position of the sliding cover plate 63 can be stabilized, keeping the tea hole 64 in an open or closed state.

[0053] To further reduce the resistance when the sliding cover 63 slides, such as Figure 11As shown, a sliding ridge 6233 is also provided at the bottom of the sliding groove 623 located between the two positioning ridges 6231. This reduces the contact area between the arc-shaped ridge 633 and the sliding ridge 6233, resulting in less sliding resistance when the arc-shaped ridge 633 slides in the sliding groove 623, thus allowing for smoother sliding.

[0054] To quickly assemble the insulated cup body 1 with the electric heating base 3, such as Figure 4 , Figure 6 As shown, the insulated cup body 1 includes an insulated inner liner 11, an extension cover 12 disposed at the bottom of the insulated inner liner 11, and a protective shell 13 fitted over the outer sides of the insulated inner liner 11 and the extension cover 12. The insulated inner liner 11 and the extension cover 12 are preferably made of stainless steel and are connected together by welding. The protective shell 13 is preferably made of tough PP material. The electric heating base 3 includes a lower control part 32 and an upper heating part 31 embedded in the extension cover 12. The connection between the lower control part 32 and the upper heating part 31 forms an inserting annular groove 33. The bottom of the extension cover 12 and the bottom of the protective shell 13 are respectively inserted into the inserting annular groove 33, thereby assembling the insulated cup body 1 and the electric heating base 3 together. This allows the insulated cup body 1 and the heating base 3 to be quickly snapped together, thereby greatly improving assembly efficiency.

[0055] To further improve the strength of the above-mentioned fastening structure and enhance product quality, such as Figure 6 As shown, the bottom of the extension cover 12 is provided with an outwardly extending inserting protruding ring portion 121, and the bottom of the protective shell 13 is provided with an inwardly extending inserting step portion 131. The inserting protruding ring portion 121 and the inserting step portion 131 are respectively inserted into the inserting ring groove 33. The thermos cup body 1 and the electric heating base 3 are assembled together by utilizing the elastic force generated by the deformation of the material, and the protective shell 13 is flush with the outer side of the lower control part 32.

[0056] like Figure 1 , Figure 2 , Figure 6 As shown, threaded posts are respectively provided at the center of the upper heating part 31 and the lower control part 32, and the lower control part 32 and the upper heating part 31 are connected together by screws. The upper heating part 31 is hidden inside the extension cover 12 and closely fits the bottom of the heat-insulating inner liner 11, which is conducive to rapid heating of the heat-insulating inner liner 11, and can also improve the impact resistance of the upper heating part 31 and extend its service life.
