[0022] This utility model proposes a thermos that is convenient to take out and store.

[0023] Please see Figures 1 to 7 In one embodiment of this utility model, the thermos includes: The body of the pot 2 has a mounting portion 21 extending axially along its outer wall; and Handle 1, comprising a handle base 11 and two handle portions 12 rotatably mounted on the handle base 11, the handle base 11 being slidably engaged with the mounting portion 21 to prevent the handle base 11 from disengaging from the mounting portion 21 radially along the body 2; and Fastener 14 is inserted through handle seat 11 and connected to mounting part 21 to prevent handle seat 11 from disengaging from mounting part 21 along the axial direction of kettle body 2; The two handle portions 12 have a use position and a storage position. In the use position, the two handle portions 12 abut against each other on the side that is close to each other. The two handle portions 12 are rotated in opposite directions to switch to the storage position.

[0024] Specifically, the handle portion 12 is rotatably mounted on the handle base 11, thereby allowing the handle portion 12 to rotate relative to the handle base 11, that is, relative to the kettle body 2. (See usage position) Figure 1 and Figure 2 The two handle portions 12 abut against each other on their closest sides, thus forming a single unit for the user to grip. At this point, the two handle portions 12 are set at an angle to the body 2, that is, the handle portion 12 and the body 2 are set at an angle along the tangent at their mounting point, to facilitate the user's grip. Optionally, the angle between the two handle portions 12 and the body 2 can be equal to 90°, or it can be less than 90° or greater than 90°. (See storage location...) Figure 3 and Figure 4 The two handles 12 are positioned such that their opposite sides abut against the body 2, thus reducing the axial dimension of the thermos and minimizing the space occupied by the handles 12; alternatively, the distance between the two handles 12 and the outer surface of the body 2 is a preset distance, such as less than or equal to 10mm. In other words, when the thermos needs to be stored, the user can flexibly switch the handles 12 to the storage position, eliminating the need to reserve storage space for the handles 1, thereby facilitating the storage of the thermos and making it convenient for daily use.

[0025] Please see Figure 1 and Figure 3 , Figure 1 and Figure 3 The up and down direction indicated in the figure is the axial direction of the body 2. Therefore, the handle seat 11 moves along the axial direction of the body 2, that is, the handle seat 11 can move upward or downward relative to the body 2.

[0026] In existing technologies, there are several ways to install the handle and body of the thermos without detachment: the handle is directly welded or glued to the body, but this method may result in the handle accidentally falling off over time; the handle can also be integrally molded into the body, which, while preventing the handle from detaching, undoubtedly makes the manufacturing process of the thermos more difficult; or the handle can be installed to the body using fasteners, which, while balancing installation stability and ease of manufacturing, often requires multiple fasteners to ensure stable installation, thus affecting the overall structural integrity and aesthetics of the thermos.

[0027] Therefore, in order to balance the processing difficulty of the thermos, the installation stability of the handle 1, and the overall appearance of the thermos, in this embodiment of the utility model, the handle seat 11 is slidably engaged with the mounting part 21 to prevent the handle seat 11 from detaching from the mounting part 21 in the radial direction of the thermos body 2; the fastener 14 passes through the handle seat 11 and is connected to the mounting part 21 to prevent the handle seat 11 from detaching from the mounting part 21 in the axial direction of the thermos body 2; specifically, the mounting part 21 can be integrally formed on the thermos body 2. The handle seat 11 slides along the axial direction of the body 2 to engage with the mounting part 21, thereby completing the initial installation and positioning of the handle 1. The engagement between the handle seat 11 and the mounting part 21 can restrict the handle seat 11 from detaching from the mounting part 21 in the radial direction of the body 2, thus ensuring that the handle 1 will not move radially relative to the body 2. Then, the fastener 14 connects the handle seat 11 and the mounting part 21, thereby restricting the handle seat 11 from detaching from the mounting part 21 in the axial direction of the body 2, thus ensuring that the handle 1 will not move axially relative to the body 2. This installation method often only requires one fastener 14 to fix the handle 1, thus taking into account the processing difficulty of the thermos, the installation stability of the handle 1, and the overall appearance of the thermos.

[0028] Furthermore, the mounting part 21 is provided with a slot 211, and the handle seat 11 is provided with a corresponding snap-fit ​​part 113. The handle seat 11 slides along the axial direction of the pot body 2, and the snap-fit ​​part 113 snaps into the slot 211. The fastener 14 is provided on the end face of the handle seat 11 along the axial direction of the pot body 2 to restrict the snap-fit ​​part 113 from coming out of the slot 211. That is, the engagement between the snap-fit ​​part 113 and the slot 211 not only restricts the handle 1 from disengaging from the mounting part 21 radially along the body 2, but also restricts the handle 1 from disengaging from the mounting part 21 in one axial direction along the body 2. Therefore, as long as the fastener 14 restricts the handle 1 from disengaging from the mounting part 21 in the other axial direction along the body 2, the installation of the handle 1 can be guaranteed to be stable. Therefore, the fastener 14 is provided on the end face of the handle seat 11 along the axial direction of the body 2. Compared with the fastener 14 being directly installed on the side of the handle seat 11 away from the body 2, this solution installs the fastener 14 on the end face of the handle seat 11 along the axial direction of the body 2, making it less likely for the user to see the fastener 14 during use, thereby improving the appearance integration of the handle 1 and the body 2. Of course, in other embodiments, the fastener 14 can also be installed on the side of the handle seat 11 away from the body 2, or provided on the side of the handle seat 11 parallel to the axial direction of the body 2.

[0029] The engagement between the latching portion 113 and the slot 211 restricts the upward sliding of the handle 1. A corresponding fastener 14 is located on the lower end face of the mounting portion 21. For example, see [reference needed]. Figure 5 and Figure 6The lower side of the slot 211 has an opening. The engaging part 113 is inserted into the slot 211 through the opening and moves upward to engage with the slot 211. The fastener 14 is located on the lower end face of the mounting part 21. That is, when the handle base 11 moves upward relative to the body 2, the engaging part 113 and the slot 211 can engage. After engagement, if the handle base 11 moves downward relative to the body 2, the engaging part 113 may disengage from the slot 211 through the opening. Therefore, the fastener 14 restricts the downward movement of the handle 1, thereby ensuring the stable engagement of the engaging part 113 and the slot 211, and further fixing the handle base 11 to the body 2, thus achieving stable fixation of the handle 1. Moreover, the fastener 14 is located on the lower end face of the handle base 11, which can also effectively hide the fastener 14, so that the user will basically not see the fastener 14 during daily use, further improving the overall appearance of the thermos. Furthermore, during daily use, when a user picks up the thermos, the body 2 moves downwards relative to the handle 1 due to its own weight. Therefore, in daily use, the handle 1 supports the body 2 through the cooperation of the slot 211 and the engaging part 113. Thus, even if the fastener 14 accidentally loosens, the body 2 is not easily detached from the handle 1, further improving safety. Of course, in other embodiments, the engagement of the engaging part 113 and the slot 211 can restrict the downward sliding of the handle 1, with the corresponding fastener 14 located on the upper surface of the mounting part 21. The fastener 14 can be configured as a screw or bolt.

[0030] To facilitate the fastener 14 to be fastened to the mounting part 21, in one embodiment, the thickness of the end of the mounting part 21 along the axial direction of the pot body 2 is greater than the thickness of the mounting part 21 at other locations. In other words, the end of the mounting part 21 along the axial direction of the pot body 2 is thickened, thereby increasing the end face area of ​​the mounting part 21 and facilitating the installation of the fastener 14 and the mounting part 21.

[0031] Furthermore, in order to further ensure the installation stability of the handle 1, the mounting part 21 can be provided with multiple slots 211, which are arranged at intervals along the axial direction of the pot body 2. The handle seat 11 is also provided with multiple snap-fit ​​parts 113, and each snap-fit ​​part 113 snaps into one slot 211.

[0032] Furthermore, to facilitate the engagement of the snap-fit ​​part 113 into the slot 211, in one embodiment, the slot 211 includes a connected mounting section 212 and a snap-fit ​​section 213. The snap-fit ​​section 213 and the mounting section 212 are arranged along the axial direction of the pot body 2, and the width of the mounting section 212 is greater than or equal to the width of the snap-fit ​​section 213. The mounting part 21 is inserted into the mounting section 212, and the handle 11 is slid towards the snap-fit ​​section 213 so that the snap-fit ​​part 113 snaps into the snap-fit ​​section 213. Specifically, when the handle seat 11 approaches the mounting part 21 and the receiving groove 112 covers the mounting part 21, the snap-fit ​​part 113 is inserted into the slot 211 from the mounting section 212, and then the handle seat 11 is pushed upward, so that the snap-fit ​​part 113 can be inserted into the snap-fit ​​section 213, thereby the slot 211 can restrict the snap-fit ​​part 113 from coming out of the slot of the snap-fit ​​section 213, thereby realizing the snap-fit ​​between the snap-fit ​​part 113 and the slot 211.

[0033] Furthermore, the inner side of the slot 211 is provided with a first guide surface, and the side of the engaging part 113 facing away from the pot body 2 is provided with a second guide surface. The first guide surface and the second guide surface slide against each other to guide the engaging part 113 towards the slot 211. Specifically, the slot 211 has a first guide surface on the inner side facing the pot body 2, and the distance from the second guide surface to the pot body 2 decreases in the direction away from the mounting section 212. This means that the radial depth of the engaging section 213 relative to the pot body 2 gradually decreases in the direction away from the mounting section 212, thereby facilitating the insertion of the engaging part 113 into the engaging section 213. In order to improve the compatibility between the engaging part 113 and the slot 211, the side of the engaging part 113 facing away from the pot body 2 is provided with a second guide surface. So when the engaging part 113 and the second slot 211 are engaged, the first guide surface and the second guide surface fit together, thereby improving the engagement stability.

[0034] Furthermore, to further conceal the fastener 14, in one embodiment, the end face of the handle base 11 is provided with a recessed groove 114. The fastener 14 passes through the handle base 11 via the recessed groove 114, and the recessed groove 114 is located close to the body 2 of the kettle. Specifically, the presence of the recessed groove 114 allows the fastener 14 to completely sink into the recessed groove 114 after installation, that is, into the handle base 11, thereby further concealing the fastener 14. Moreover, the recessed groove 114 is located close to the body 2 of the kettle, making it difficult for the user to observe its presence during normal use, thus further improving the overall appearance of the thermos.

[0035] Furthermore, the handle base 11 has a receiving groove 112 on the side facing the kettle body 2. The mounting part 21 is inserted into the receiving groove 112, the snap-fit ​​part 113 is provided in the receiving groove 112, and the fastener 14 passes through the groove wall of the receiving groove 112 and is fastened to the mounting part 21. Specifically, the handle base 11 has a receiving groove 112 on the side facing the kettle body 2. When the handle 1 is installed, the mounting part 21 is inserted into the receiving groove 112. On the one hand, the receiving groove 112 and the mounting part 21 are inserted into each other to realize the snap-fit ​​between the handle base 11 and the kettle body 2, thereby preventing the handle base 11 from moving accidentally relative to the kettle body 2 and assisting the fastener 14 in fixing the handle base 11. On the other hand, it increases the connection area between the handle base 11 and the mounting part 21, which facilitates the assembly of the fastener 14. In addition, the cooperation between the mounting part 21 and the receiving groove 112 can reduce the assembly thickness of the mounting part 21 and the handle seat 11, while hiding the receiving groove 112 and the snap-fit ​​between the two in the receiving groove 112, which helps to improve the overall appearance of the thermos.

[0036] Please see Figure 1 , Figure 2 , Figures 8 to 22 In an embodiment of this utility model, an elastic limiting structure 13 is provided between the handle portion 12 and the handle seat 11; in the use position, the elastic limiting structure 13 causes the sides of the two handle portions 12 that are close to each other to abut against each other; in the storage position, the elastic limiting structure 13 causes the sides of the two handle portions 12 that are opposite to each other to abut against the body of the kettle 2.

[0037] Specifically, the elastic limiting structure 13 allows the handle portion 12 to press firmly against the body 2, thus ensuring the handle portion 12 is stably in a retracted state, facilitating the storage of the thermos. The elastic limiting structure 13 also allows the two handle portions 12 to press together on their adjacent sides, ensuring the connection stability of the two handle portions 12 during use, thus facilitating user operation. In other embodiments, each of the two handle portions 12 has a magnetic suction member 125 on its adjacent side. In the use position, the two magnetic suction members 125 are magnetically connected, further improving the connection stability of the two handle portions 12 during use. One of the two magnetic suction members 125 can be configured as a magnet, while the other can be configured as a magnetic material such as iron, cobalt, or nickel; of course, both magnetic suction members 125 can also be configured as magnets.

[0038] In this design, the rotation angle of the two handles 12 is typically greater than 90°, allowing them to fit more closely to the outer surface of the pot body 2, further reducing storage space. In this design, the rotation angle of both handles 12 is 120°. During the design process, designers can rationally select the rotation angle of the two handles 12 according to design requirements and the radius of the pot body 2. Furthermore, the opposite side of the two handles 12 has an arc-shaped surface 123 that fits against the outer circumference of the pot body 2. This arc-shaped surface 123 is close to the outer surface of the pot body 2, allowing it to fit snugly against the outer circumference of the pot body 2 at this storage location, thereby further improving storage stability and reducing the possibility of handle 12 failure due to compression during storage.

[0039] In one embodiment, reference is made to Figures 8 to 11 The elastic limiting structure 13 includes a rotating shaft 131, and a first limiting member 132, a second limiting member 133, and a first elastic member 134 sleeved on the rotating shaft 131. One end of the handle seat 11 is provided with a first rotating shaft hole 115, and the rotating shaft 131 is installed in the first rotating shaft hole 115. The first limiting member 132 can move axially along the first rotating shaft hole 115. The second limiting member 133 connects the rotating shaft 131 and the handle portion 12. The side of the first limiting member 132 facing the second limiting member 133. The device is provided with a first limiting protrusion 1321, and a first limiting groove 1322 is formed between two adjacent first limiting protrusions 1321. The second limiting member 133 is provided with a second limiting protrusion 1331 adapted to the first limiting groove 1322 and a second limiting groove 1332 adapted to the first limiting protrusion 1321. The first elastic member 134 is provided on the side of the first limiting member 132 away from the second limiting member 133. The handle 1 can drive the second limiting member 133 to rotate relative to the first limiting member 132. In the storage position, the first limiting protrusion 1321 extends into a second limiting groove 1332, and the first elastic member 134 causes the first limiting protrusion 1321 to press against the second limiting member 133, so that the handle portion 12 abuts against the body 2; in the use position, the first limiting protrusion 1321 extends into another second limiting groove 1332, and the first elastic member 134 causes the first limiting protrusion 1321 to press against the second limiting member 133, so that the two handle portions 12 abut against each other on the side that is close to each other.

[0040] Specifically, the rotating shaft 131 is rotatably installed within the first rotating shaft hole 115. Therefore, to reduce the likelihood of the rotating shaft 131 dislodging from the first rotating shaft hole 115, in this design, one of the inner wall of the first rotating shaft hole 115 and the circumferential direction of the rotating shaft 131 is provided with an annular retaining protrusion 1151, and the other is provided with an annular retaining groove 1311. The annular retaining protrusion 1151 can be slidably installed in the annular retaining groove 1311. The first limiting member 132 is sleeved on the rotating shaft 131, and the first limiting member 132 can be limited and installed in the first rotating shaft hole 115, thereby allowing the first rotating shaft hole 115 to restrict the rotation of the first limiting member 132, so that the first limiting member 132 can only slide along the axial direction of the first rotating shaft hole 115. For example, a limiting surface is provided on the circumference of the first rotating shaft hole 115, and the limiting surface restricts the rotation of the first limiting member 132 within the first rotating shaft hole 115. That is, at least a portion of the cross-section of the first pivot hole 115 is non-circular, and the cross-section of the corresponding first limiting member 132 is also non-circular, thereby enabling them to rotate and limit each other. The axial direction of the first pivot hole 115 can be polygonal, and the cross-section of the corresponding first limiting member 132 is also polygonal.

[0041] One end of the first elastic member 134 abuts against the side of the first limiting member 132 away from the second limiting member 133, and the other end abuts against the wall of the first rotating shaft hole 115. The first elastic member 134 enables the first limiting member 132 to always have a tendency to press against the second limiting member 133. The second limiting member 133 can fix the handle portion 12 and the rotating shaft 131, so that the handle 1 can drive the second limiting member 133 and the rotating shaft 131 to rotate relative to the first limiting member 132, and enable the first limiting member 132 and the second limiting member 133 to interact with each other, so that the first limiting member 132 can move along the axial direction of the first rotating shaft hole 115, so that the first limiting member 132 and the second limiting member 133 can jointly adjust the length of the first elastic member 134, thereby adjusting the elastic potential energy of the first elastic member 134.

[0042] Specifically, when the first limiting protrusion 1321 is fully engaged with the second limiting groove 1332, the corresponding second limiting protrusion 1331 is engaged with the first limiting groove 1322. At this time, the length of the first elastic member 134 is at its maximum, the elastic potential energy of the first elastic member 134 is at its minimum (possibly approaching zero), and the pressing force of the first elastic member 134 on the first limiting member 132 is at its minimum (possibly approaching zero). When the end of the first limiting protrusion 1321 abuts against the end of the second limiting protrusion 1331, the corresponding first limiting groove 1322 and the second limiting groove 1332 are positioned opposite each other. At this time, the first elastic member 1321... When the length of 34 is at its maximum, the elastic potential energy of the first elastic element 134 is at its maximum, and the pressing force of the first elastic element 134 on the first limiting element 132 is also at its maximum. This position is also the middle position of the handle 12, which is located between the storage position and the use position. When the second limiting element 133 continues to rotate relative to the first limiting element 132 from the middle position, the first limiting protrusion 1321 slides towards the second limiting groove 1332, and correspondingly the second limiting protrusion 1331 slides towards the first limiting groove 1322. When the first limiting protrusion 1321 is not fully engaged in the second limiting groove 1332 (see...), Figure 21 At this time, the first elastic element 134 is partially compressed, and the first elastic element 134 has a certain clamping force on the first limiting element 132. Under the action of this clamping force, the first limiting protrusion 1321 always has the tendency to be completely inserted into the second limiting groove 1332. That is, the first limiting element 132 can make the second limiting element 133 have the tendency to continue to rotate, so that the handle part 12 also has the tendency to continue to rotate.

[0043] Therefore, in the storage position, the first limiting protrusion 1321 partially extends into a second limiting groove 1332, thereby using the first elastic member 134 to press the first limiting protrusion 1321 against the side wall of the second limiting groove 1332, so that the second limiting member 133 has a tendency to continue rotating, thereby causing the handle 12 to press against the body 2; in the use position, the first limiting protrusion 1321 partially extends into another second limiting groove 1332, thereby using the first elastic member 134 to press the first limiting protrusion 1321 against the side wall of the second limiting groove 1332, so that the second limiting member 133 has a tendency to continue rotating, so that the two handles 12 are close to each other and press against each other.

[0044] Furthermore, when the handle 1 moves from the middle position to the storage position, the user only needs to gently flick the handle part 12, and the elastic limiting structure 13 can push the handle 1 from the middle position to the storage position; when the handle 1 moves from the middle position to the use position, the user only needs to gently flick the handle part 12, and the elastic limiting structure 13 can push the handle 1 from the middle position to the use position, thereby facilitating the switching of the handle part 12 in different positions and improving the ease of use of the handle 1.

[0045] Furthermore, the first limiting protrusion 1321 is an approximately triangular structure, facilitating the switching of the handle 12 to different positions. Of course, in other embodiments, the first limiting protrusion 1321 can also be approximately trapezoidal or semi-circular. The intermediate position can be precisely located between the storage position and the use position, meaning the rotation angle from the intermediate position to the storage position is the same as the rotation angle from the intermediate position to the use position. In this case, the clamping force of the handle 12 on the kettle body 2 is equal to the clamping force between the two handles 12. Of course, in other embodiments, the intermediate position may not be located between the storage position and the use position.

[0046] However, under the action of this elastic limiting structure 13, when the handle 1 moves from the middle position to the storage position, it often has a certain impact force, which may cause the handle 1 to collide with the body 2, which is not conducive to the service life of the body 2 and also affects the user's experience; similarly, when the handle 1 moves from the middle position to the use position, it often has a certain impact force, which may also cause the two handle parts 12 to collide. Therefore, in one embodiment, please refer to Figure 8 , Figure 9 and Figure 12 The handle portion 12 includes a first rotating end 121 and a second rotating end 122. The first rotating end 121 is rotatably mounted to one end of the handle base 11 via an elastic limiting structure 13. The other end of the handle base 11 is provided with a second rotating shaft hole 116, and the hole wall of the second rotating shaft hole 116 is provided with an arc-shaped groove 1161. A limiting protrusion 1221 protrudes from the side of the second rotating end 122. The second rotating end 122 is rotatably mounted to the second rotating shaft hole 116, and the limiting protrusion 1221 is slidably engaged with the arc-shaped groove 1161. In the storage position, the limiting protrusion 1221... 21 abuts against one end of the arc-shaped groove 1161, thereby limiting the handle 12 and reducing the possibility of the handle 1 colliding with the body 2; in the use position, the limiting protrusion 1221 abuts against the other end of the arc-shaped groove 1161, thereby limiting the handle 12 and reducing the possibility of the two handles 12 colliding; when the handle 12 rotates between the storage position and the use position, the limiting protrusion 1221 slides between the arc-shaped grooves 1161, thereby allowing the arc-shaped grooves 1161 to further guide the rotation of the handle 12.

[0047] Please see Figure 13 , Figure 15 and Figure 19In another embodiment of this utility model, the handle portion 12 has a rotating portion 124, and a third limiting protrusion 1241 protrudes from one axial side of the rotating portion 124. The handle seat 11 has an arc-shaped limiting hole section 1162. The rotating portion 124 is rotatably mounted on the handle seat 11, and the third limiting protrusion 1241 is rotatably mounted on the arc-shaped limiting hole section 1162. In the storage position, the third limiting protrusion 1241 abuts against one end of the arc-shaped limiting hole section 1162. In the use position, the third limiting protrusion 1241 abuts against the other end of the arc-shaped limiting hole section 1162. Specifically, the third limiting protrusion 1241 protrudes from one axial side of the rotating part 124. When the handle part 12 rotates, the rotating part 124 can drive the third limiting protrusion 1241 to rotate around the rotating part 124 as an axis. The handle seat 11 is provided with an arc-shaped limiting hole section 1162, which can limit the third limiting protrusion 1241. In the retracted position, the third limiting protrusion 1241 abuts against one end of the arc-shaped limiting hole section 1162, thereby limiting the handle part 12. The third limiting protrusion 1241 abuts against the other end of the arc-shaped limiting hole section 1162 in the storage position, thereby limiting the handle 12 and reducing the possibility of collision between the two handles 12. When the handle 12 rotates between the storage position and the use position, the third limiting protrusion 1241 slides in the arc-shaped limiting hole section 1162, thereby enabling the arc-shaped limiting hole section 1162 to further guide the rotation of the handle 12.

[0048] Understandably, the cooperation between the third limiting protrusion 1241 and the arc-shaped limiting hole segment 1162 is similar to the cooperation between the limiting card protrusion 1221 and the arc-shaped card groove 1161. Therefore, in order to simplify the structure and reduce structural redundancy, the cooperation between the third limiting protrusion 1241 and the arc-shaped limiting hole segment 1162 and the cooperation between the limiting card protrusion 1221 and the arc-shaped card groove 1161 can be set selectively.

[0049] For further details, please refer to Figures 13 to 17 The elastic limiting structure 13 includes a second elastic member 135, the two ends of which are respectively connected to two third limiting protrusions 1241. The third limiting protrusions 1241 can rotate about the rotating part 124 as an axis to adjust the length of the second elastic member 135. In the storage position, the third limiting protrusions 1241 rotate to the side of the rotating part 124 away from the pot body 2. In the use position, the third limiting protrusions 1241 rotate to the side of the rotating part 124 close to the pot body 2.

[0050] Specifically, during the rotation of the third limiting protrusion 1241 around the rotating part 124, when the two third limiting protrusions 1241 rotate to the side where they are close to each other, the distance between the two third limiting protrusions 1241 is the shortest, corresponding to the shortest length of the second elastic element 135 and the minimum elastic potential energy of the second elastic element 135, which is set as the first extreme position; when the two third limiting protrusions 1241 rotate to the side where they are opposite to each other, the distance between the two third limiting protrusions 1241 is the farthest, corresponding to the longest length of the second elastic element 135. The second elastic element 135 has the greatest elastic potential energy and is set as the second limit position (corresponding to the middle position of the handle 12). When the two third limiting protrusions 1241 rotate to between the limit position and the second limit position, that is, when the third limiting protrusions 1241 rotate to the side of the rotating part 124 away from the body 2 or towards the body 2, under the pulling force of the second elastic element 135, the third limiting protrusions 1241 always tend to move closer to each other, so that in the storage position, the handle 12 presses against the body 2; and in the use position, the two handles 12 press against each other.

[0051] It should be noted that, in the storage position, the third limiting protrusion 1241 rotates to the side of the rotating part 124 away from the body 2, which does not mean that the third limiting protrusion 1241 is completely located on the side of the rotating part 124 away from the body 2. That is, the third limiting protrusion 1241 is not located in the radial direction of the body 2, but can form a certain angle with the radial direction of the body 2. In other words, the storage position is not completely located in the middle of the first and second extreme positions, and it can be set according to the actual rotation angle of the handle 12. In the use position, the third limiting protrusion 1241 rotates to the side of the rotating part 124 close to the body 2, which does not mean that the third limiting protrusion 1241 is completely located on the side of the rotating part 124 away from the body 2. That is, the third limiting protrusion 1241 is not directly opposite the body 2, but can form a certain angle with the radial direction of the body 2. In other words, the use position is not completely located in the middle of the first and second extreme positions, and it can be set according to the actual rotation angle of the handle 12. In this design, the angle of the arc-shaped limiting hole segment 1162 is equal to the sum of the rotation angle of the handle portion 12 and the occupancy angle of the third limiting protrusion 1241. In this design, the third limiting protrusion 1241 is configured as a fan shape with an included angle of 120°. The rotation angle of the handle portion 12 is also 120°. Therefore, the angle of the arc-shaped limiting hole segment 1162 is 240°.

[0052] To facilitate the installation of the second elastic element 135, hooks are provided at both ends of the second elastic element 135, and the two hooks are respectively attached to the two third limiting protrusions 1241. In one embodiment, the second elastic element 135 is configured as a tension spring. At the middle position, the third limiting protrusions 1241 rotate to the side opposite to the two rotating parts 124, at which point the elastic potential energy of the second elastic element 135 is at its maximum. Under the elastic action of the second elastic element 135, when the handle 1 moves from the middle position to the storage position, the user only needs to gently flick the handle part 12 to automatically move the handle part 12 to the storage position; when the handle 1 moves from the middle position to the use position, the user only needs to gently flick the handle part 12 to automatically move the handle part 12 to the use position, thereby facilitating the switching of the handle part 12 between different positions and improving the ease of use of the handle 1.

[0053] Please see Figures 18 to 22 In another embodiment of this utility model, the elastic limiting structure 13 includes a limiting spring 136, which is disposed on the side of the rotating part 124 near the body 2. Limiting flats 1242 are provided on both opposite sides of the rotating part 124. In the storage position, one end of the limiting spring 136 abuts against one of the limiting flats 1242. In the use position, one end of the limiting spring 136 abuts against the other limiting flat 1242.

[0054] Specifically, in this embodiment, two rotating parts 124 are spaced apart and located at opposite ends of the limiting spring piece 136. Since the middle of the limiting spring piece 136 is fixed to the handle base 11, and limiting flat parts 1242 are provided on opposite sides of the rotating parts 124, when the handle 12 drives the rotating parts 124 to rotate, it can push one end of the limiting spring piece 136 to swing, causing the limiting spring piece 136 to deform and generate elastic potential energy. This allows the handle 12 to press against the kettle body 2 in the storage position and to abut against each other in the use position. The two limiting flat parts 1242 can be arranged parallel to each other or at a certain angle, and the designer can design them according to the required rotation angle of the handle 12.

[0055] Furthermore, in the middle position, the limiting spring 136 abuts against the rotating part 124 between the two limiting flat positions 1242. At this time, the deformation of the limiting spring 136 is the greatest. Under the elastic action of the limiting spring 136, the rotating part 124 always has the tendency to make the limiting flat position 1242 abut against the limiting spring 136. Therefore, when the handle 1 moves from the middle position to the storage position, the user only needs to gently flick the handle part 12 to make the handle part 12 move automatically to the storage position; when the handle 1 moves from the middle position to the use position, the user only needs to gently flick the handle part 12 to make the handle part 12 move automatically to the use position, thereby facilitating the switching of the handle part 12 to different positions and improving the ease of use of the handle 1.

[0056] At this time, the engagement of the limiting spring 136 and the limiting flat part 1242, and the engagement of the third limiting protrusion 1241 and the arc-shaped limiting hole section 1162, can be respectively provided at the two rotating ends of the handle part 12, or they can be respectively provided at the same limiting end of the handle part 12. That is, the rotating part 124 is divided into two connected sections along its axial direction, one section is provided with the limiting flat part 1242, and the other section is provided with the third limiting protrusion 1241. The engagement structure of the third limiting protrusion 1241 and the arc-shaped limiting hole section 1162 can also be replaced by the engagement structure of the limiting locking protrusion 1221 and the arc-shaped locking groove 1161. The limiting spring 136 can be fixed to the handle seat 11 by fasteners 14 such as screws and bolts.
