[0094] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0095] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0096] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0098] This invention proposes a handle 1 for installation on a thermos flask to facilitate the handling and storage of the thermos flask. The thermos flask includes a body 2. In other embodiments, the handle 1 can also be used on a water bottle that does not have a thermos function.

[0099] Please see Figures 1 to 17 In one embodiment of the present invention, the handle 1 includes:

[0100] Mounting part 21 is assembled on the pot body 2, and mounting part 21 is provided with a first slot 217;

[0101] The handle base 11 and the handle portion 12 assembled on the handle base 11 are provided with a first snap-fit ​​portion 111 on the side of the handle base 11 facing the mounting portion 21, and a locking and releasing structure is also provided between the handle base 11 and the mounting portion 21.

[0102] The handle seat 11 moves along the axial direction of the kettle body 2, so that the first locking part 111 is locked into the first locking groove 217, so as to at least limit the radial movement of the handle seat 11 along the kettle body 2, and the locking and releasing structure can prevent the first locking part 111 from dislodging from the first locking groove 217.

[0103] Specifically, the mounting part 21 can be integrally formed into the body 2, or connected by bonding or welding. The handle base 11 and the mounting part 21 are detachable, so that when the body 2 is needed, the handle 1 can be installed on the body 2, making it convenient for the user to pick up the body 2 and for daily use; when the thermos needs to be stored, the handle 1 can be removed, so that there is no need to reserve storage space for the handle 1 of the thermos, thus making it convenient for the thermos to be stored and for daily use.

[0104] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2The up and down direction indicated in the figure is the axial direction of the pot body 2. Therefore, the handle seat 11 moves along the axial direction of the pot body 2, that is, the handle seat 11 can move upward or downward relative to the pot body 2. Designers can make designs according to actual conditions.

[0105] The handle base 11 moves axially along the body 2, causing the first engaging part 111 to engage with the first slot 217. The following explanation uses the example of the handle base 11 moving upwards relative to the body 2, allowing the first engaging part 111 and the first slot 217 to engage. After engagement, if the handle base 11 moves downwards relative to the body 2, the first engaging part 111 may disengage from the first slot 217. Therefore, the engagement of the first engaging part 111 and the first slot 217 primarily limits the radial movement of the handle 1 along the body 2. The locking and releasing structure restricts the first engaging part 111 from disengaging from the first slot 217, thus restricting the axial movement of the handle 1 along the body 2, thereby ensuring stable engagement between the first engaging part 111 and the first slot 217. Furthermore, by adding the locking and releasing structure, multi-position engagement between the mounting part 21 and the handle base 11 can be achieved, ensuring stable installation of the handle 1. Furthermore, when disassembling, the user only needs to release the latch between the protrusion 1121 and the slot 212 to disassemble the handle 1, thus facilitating quick installation of the handle 1 and making it convenient for daily use.

[0106] Furthermore, to further ensure the installation stability of the handle 1, the mounting part 21 can be provided with multiple first slots 217, which are arranged at intervals along the axial direction of the kettle body 2. Correspondingly, the handle base 11 is also provided with multiple first engaging parts 111, with each first engaging part 111 engaging with one first slot 217. In addition, the handle base 11 has a receiving groove 115 on the side facing the mounting part 21. The receiving groove 115 can accommodate the mounting part 21, thereby reducing the assembly thickness of the mounting part 21 and the handle part 12. At the same time, the receiving groove 115 and the engagement between the two are hidden within the receiving groove 115, which helps to improve the overall appearance of the thermos.

[0107] To facilitate the first snap-fit ​​portion 111 snapping into the first slot 217, in one embodiment, please refer to... Figure 2 , Figure 3 and Figure 7 The first slot 217 includes a connected mounting section 2171 and a snap-fit ​​section 2172. The snap-fit ​​section 2172 and the mounting section 2171 are arranged along the axial direction of the pot body 2. The first snap-fit ​​part 111 is inserted into the first slot 217 by the mounting section 2171 and slides towards the snap-fit ​​section 2172 to snap-fit ​​with the snap-fit ​​section 2172.

[0108] Specifically, the groove width of the mounting section 2171 is greater than the groove width of the snap-fit ​​section 2172, forming a stepped or tapering guide structure along the direction close to the snap-fit ​​section 2172, facilitating the smooth sliding of the first snap-fit ​​part 111 into the snap-fit ​​section 2172 along the circumference of the kettle body 2. When the handle seat 11 approaches the mounting part 21, and the receiving groove 115 covers the mounting part 21, the first snap-fit ​​part 111 is inserted into the first snap-fit ​​groove 217 from the mounting section 2171. Then, by pushing the handle seat 11 upward, the first snap-fit ​​part 111 can be inserted into the snap-fit ​​section 2172, thereby preventing the first snap-fit ​​part 111 from dislodging from the groove of the snap-fit ​​section 2172, thus achieving the snap-fit ​​between the first snap-fit ​​part 111 and the first snap-fit ​​groove 217.

[0109] Furthermore, a third guide surface is provided on the inner side of the first slot 217, and a fourth guide surface is provided on the side of the first engaging part 111 away from the pot body 2. The third guide surface and the fourth guide surface slide against each other to guide the first engaging part 111 towards the first slot 217. Specifically, a third guide surface is provided on the inner side of the first slot 217 facing the pot body 2, and the distance from the third guide surface to the pot body 2 decreases in the direction away from the mounting section 2171. This means that the radial depth of the engaging section 2172 in the pot body 2 gradually decreases in the direction away from the mounting section 2171, thereby facilitating the insertion of the first engaging part 111 into the engaging section 2172. Furthermore, in order to improve the compatibility between the first snap-fit ​​part 111 and the first slot 217, a fourth guide surface is provided on the side of the first snap-fit ​​part 111 away from the pot body 2. Thus, when the first snap-fit ​​part 111 and the second slot 217 snap-fit ​​together, the third guide surface and the fourth guide surface fit together, thereby improving the snap-fit ​​stability of the two.

[0110] In an embodiment of the present invention, please refer to Figures 4 to 6 , Figures 11 to 13 , Figures 15 to 17The mounting part 21 is also provided with a first magnet 213, and the handle seat 11 is provided with a second magnet 113. The first magnet 213 and the second magnet 113 interact to drive the handle part 12 to move along the axial direction of the pot body 2, so that the first engaging part 111 engages with the first slot 217. Specifically, when the handle seat 11 approaches the mounting part 21, the first magnet 213 and the second magnet 113 attract each other, thereby providing an attractive force for the receiving groove 115 to cover the mounting part 21, which facilitates the insertion of the first engaging part 111 into the mounting section 2171. Since the first magnet 213 and the second magnet 113 have the effect of minimizing the system energy when they attract each other, the first magnet 213 and the second magnet 113 tend to align with each other. Thus, under the interaction of the first magnet 213 and the second magnet 113, the handle seat 11 can be automatically pushed to move along the axial direction of the pot body 2, thereby realizing the automatic engagement of the first engaging part 111 and the first slot 217. That is, due to the interaction between the first magnet 213 and the second magnet 113, the user only needs to bring the handle base 11 close to the mounting part 21 to achieve automatic engagement between the first snap-fit ​​part 111 and the first slot 217. Furthermore, the presence of the first magnet 213 and the second magnet 113 can further improve the installation strength between the mounting part 21 and the handle base 11, thereby improving the installation stability of the handle 1.

[0111] The number of first magnets 213 and second magnets 113 can correspond to the number of first slots 217 and first engaging parts 111. For example, in one embodiment, there are two first slots 217 and two first engaging parts 111 between the mounting part 21 and the handle base 11, and correspondingly, there are two first magnets 213 and two magnets 113 between them. Of course, the number of first magnets 213 and second magnets 113 can also be unequal to the number of first slots 217 and first engaging parts 111. Furthermore, both the first magnets 213 and second magnets 113 are configured as magnetic structures, meaning they are both magnetic, and not just one of them is a magnetic suction element 125.

[0112] In one embodiment of the present invention, please refer to Figures 1 to 8 The locking and releasing structure includes a slot 212 provided in the mounting part 21 and a first rotating buckle 112 rotatably mounted on the handle seat 11. The first rotating buckle 112 is provided with a locking protrusion 1121. The first rotating buckle 112 can rotate toward the handle seat 11, so that the locking protrusion 1121 passes through the handle seat 11 and engages with the slot 212.

[0113] Specifically, the slot 212 of the mounting part 21 faces the handle seat 11, and the first rotating buckle 112 can rotate towards the handle seat 11, so that the latching protrusion 1121 passes through the handle seat 11 and engages with the slot 212. This not only ensures the engagement of the latching protrusion 1121 with the slot 212, but also improves the engagement stability of the first engaging part 111 and the first slot 217. When it is necessary to install the handle 1, bring the handle seat 11 close to the mounting part 21 so that the receiving groove 115 covers the mounting part 21, and move the handle seat 11 upward along the axial direction of the pot body 2 so that the first locking part 111 engages with the first locking groove 217; then rotate the first rotating buckle 112 towards the handle seat 11 so that the locking protrusion 1121 passes through the handle seat 11 and engages with the slot 212, thereby completing the installation of the handle 1; when it is necessary to remove the handle 1, simply rotate the first rotating buckle 112 in the opposite direction so that the locking protrusion 1121 disengages from the slot 212, and then move the handle seat 11 downward along the axial direction of the pot body 2 to release the engagement between the first locking groove 217 and the first locking part 111, thereby facilitating the removal of the handle 1.

[0114] In order to ensure the stable engagement between the protrusion 1121 and the slot 212, the inner peripheral wall of the slot 212 can be provided with protrusions, and the periphery of the protrusion 1121 can also be provided with concave points. Thus, when the protrusion 1121 is inserted into the slot 212, the protrusions are inserted into the concave points, thereby enabling the protrusion 1121 to engage with the slot 212.

[0115] Furthermore, the handle base 11 is also provided with a third magnet 214, which can attract the rotating latch to rotate towards the handle base 11. Specifically, the third magnet 214 can attract the first rotating latch 112 to rotate towards the handle base 11, therefore the first rotating latch 112 is made of magnetic materials such as iron, cobalt, and nickel. When the first latching part 111 and the second latching groove 217 are engaged, the user can gently push the first rotating latch 112, or even without the user pushing the first rotating latch 112, to make the latching protrusion 1121 of the first rotating latch 112 engage with the slot 212, further facilitating the installation of the handle 1. Moreover, the third magnet 214 can generate an attractive force on the first rotating latch 112, therefore the third magnet 214 can make the latching protrusion 1121 further tighten with the slot 212, reducing the possibility of the latching protrusion 1121 falling out of the slot 212, thereby further improving the installation stability of the handle 1.

[0116] Furthermore, the mounting part 21 is provided with a protrusion 215 protruding towards the handle seat 11, and the protrusion 215 is provided with a first guide surface 216 on the side facing the handle part 12. The handle seat 11 is provided with a clearance hole 114, and the protrusion 215 can be inserted into the clearance hole 114. The first rotating buckle 112 is provided with a second guide surface 1122 at the clearance hole 114. When the handle seat 11 moves along the axial direction of the kettle body 2, the first guide surface 216 and the second guide surface 1122 slide against each other to move the first rotating buckle 112 to rotate towards the handle seat 11. That is, when the first latching part 111 and the first slot 217 are latched, the first guide surface 216 of the protrusion 215 slides against the second guide surface 1122, thereby causing the first rotating latch 112 to rotate towards the handle base 11, which facilitates the third magnet 214 to attract the first rotating latch 112 and reduces the problem of the first rotating latch 112 and the handle part 12 rotating too much and the attraction failing; at the same time, when the handle 1 needs to be disassembled, the user rotates the first rotating latch 112 away from the handle base 11. At this time, the second guide surface 1122 can act on the first guide surface 216, thereby causing the handle base 11 to slide relative to the mounting part 21, thereby releasing the latching of the first latching part 111 and the second slot 217 at the same time as releasing the latching of the protrusion 1121 and the slot 212.

[0117] See again Figures 1 to 8 In this embodiment, during the installation process, the user only needs to bring the handle seat 11 close to the mounting part 21. Under the mutual attraction of the first magnet 213 and the second magnet 113, and by using the magnetic force of the two to minimize the system energy, the handle seat 11 is driven to move along the axial direction of the pot body 2, so that the first snap-fit ​​part 111 automatically snaps into the first slot 217. At the same time as the handle seat 11 moves along the axial direction of the pot body 2, the first guide surface 216 slides against the second guide surface 1122, thereby causing the first rotating buckle 112 to rotate towards the handle seat 11, so as to reduce the included angle between the first rotating buckle 112 and the handle part 12. Then the third magnet 214 further attracts the first rotating buckle 112 to rotate towards the handle part 12, so that the snap protrusion 1121 automatically snaps into the slot 212. Therefore, in this solution, the user does not need to manually connect the handle base 11 and the mounting part 21, which facilitates the quick installation of the handle 1. When it is necessary to remove the handle 1, simply turn the first rotating buckle 112 away from the handle base 11 to remove the handle 1, which facilitates the user to quickly install and remove the handle 1 for convenient use.

[0118] In another embodiment of the invention, please refer to Figures 9 to 17 The locking and releasing structure includes a second slot 116 provided in one of the mounting part 21 and the handle seat 11, and a second rotating buckle 211 rotatably mounted in the other.

[0119] When the first latching part 111 is latched into the first slot 217, one end of the second rotating latch 211 is latched into the second slot 116 to prevent the first latching part 111 from coming out of the first slot 217.

[0120] Specifically, the second rotating latch 211 is rotatably configured and is inclined relative to the mounting portion 21 or the handle base 11. That is, one end of the second rotating latch 211 is close to the mounting portion 21, and the other end is close to the handle base 11. This allows one end of the second rotating latch 211 to engage with the second slot 116, preventing the handle base 11 from moving downwards relative to the mounting portion 21 and preventing the first engaging portion 111 from disengaging from the first slot 217. This allows the mounting portion 21 and the handle base 11 to be engaged by the locking and releasing structure. When it is necessary to release the locking and releasing structure, simply rotate the second rotating latch 211 in the opposite direction, causing that end of the second rotating latch 211 to disengage from the second slot 116, thus facilitating the removal of the handle 1.

[0121] When it is necessary to release the locking and releasing structure, in one embodiment, the locking and releasing structure further includes an unlocking hole 118 provided on the handle seat 11, and the unlocking part 1181 is slidably inserted into the unlocking hole 118; the unlocking part 1181 can slide towards the mounting part 21 to push the second rotating buckle 211 to the side near the first locking part 111 and swing towards the mounting part 21, so that the second rotating buckle 211 disengages from the second slot 116. Specifically, the unlocking part 1181 can be limited and installed in the unlocking hole 118, that is, the unlocking part 1181 will not come out of the unlocking hole 118. When it is necessary to release the engagement of the second rotating buckle 211 and the second slot 116, it is only necessary to press the unlocking part 1181. The unlocking part 1181 can also be set independently from the unlocking hole 118. When it is necessary to release the engagement of the second rotating buckle 211 and the second slot 116, the unlocking part 1181 is inserted into the unlocking hole 118 to press the side of the second rotating buckle 211 near the first engagement part 111, thereby releasing the lock.

[0122] The second slot 116 can be provided in the mounting part 21, and the corresponding second rotating buckle 211 can be provided in the handle seat 11; the second slot 116 can also be provided in the handle seat 11, and the corresponding second rotating buckle 211 can be provided in the mounting part 21.

[0123] In one implementation, please refer to Figures 9 to 13The second slot 116 is provided in the mounting part 21, and the second rotating buckle 211 is rotatably mounted on the handle seat 11. The end of the second rotating buckle 211 away from the first engaging part 111 extends obliquely toward the mounting part 21, and the other end abuts against the handle seat 11. When the first engaging part 111 engages with the first slot 217, the end of the second rotating buckle 211 away from the first engaging part 111 engages with the second slot 116. That is, when the second slot 116 can be provided in the mounting part 21, and the corresponding second rotating buckle 211 is provided in the handle seat 11, the lower part of the second rotating buckle 211 engages with the second slot 116, thereby preventing the handle seat 11 from moving downward, so as to prevent the first engaging part 111 and the first slot 217 from disengaging, while the upper end can abut against the handle seat 11, thereby ensuring the stable engagement of the second slot 116 and the second rotating buckle 211.

[0124] Furthermore, the handle base 11 is also provided with a fourth magnet 117, which can attract the end of the second rotating latch 211 near the first latching portion 111 to press against the handle base 11, thereby further improving the engagement stability of the second latching groove 116 and the second rotating latch 211. In another embodiment, a first elastic member 2111 can also be provided between the handle base 11 and the second rotating latch 211. The first elastic member 2111 can cause the end of the second rotating latch 211 near the first latching portion 111 to press against the handle base 11. The first elastic member 2111 can be an elastic torsion spring.

[0125] Please refer to it again. Figures 9 to 13 In this embodiment, during the installation process of the handle 1, the user only needs to bring the handle base 11 close to the mounting part 21. Under the mutual attraction of the first magnet 213 and the second magnet 113, and by utilizing the magnetic force of the two to minimize system energy, the handle base 11 is driven to move along the axial direction of the kettle body 2, so that the first locking part 111 automatically engages with the first slot 217. When the first locking part 111 and the first slot 217 are engaged, one end of the second rotating buckle 211 automatically engages with the second slot 116. Therefore, in this solution, the user does not need to manually engage the handle base 11 and the mounting part 21, thus facilitating the quick installation of the handle 1. Under the action of the fourth magnet 117, the second rotating buckle 211 is locked in the second slot 116. When it is necessary to remove the handle 1, simply press the unlocking part 1181 to make the second rotating buckle 211 rotate in the opposite direction, so that the end of the second rotating buckle 211 away from the first locking part 111 is disengaged from the second slot 116.

[0126] In another embodiment, please refer to Figures 14 to 17The second slot 116 is provided on the handle base 11, and the second rotating buckle 211 is rotatably mounted on the mounting part 21; and the end of the second rotating buckle 211 near the first engaging part 111 extends obliquely toward the handle base 11; when the first engaging part 111 engages with the first slot 217, the end of the second rotating buckle 211 near the first engaging part 111 engages with the second slot 116. That is, when the second slot 116 can be provided on the handle base 11, and the corresponding second rotating buckle 211 is provided on the mounting part 21, the upper part of the second rotating buckle 211 engages with the second slot 116, thereby preventing the handle base 11 from moving downward, so as to prevent the first engaging part 111 and the first slot 217 from disengaging.

[0127] Furthermore, a first elastic element 2111 is provided between the second rotating latch 211 and the handle base 11. The first elastic element 2111 causes the end of the second rotating latch 211 near the first engaging portion 111 to tend to swing towards the handle base 11. The first elastic element 2111 can be an elastic torsion spring. In another embodiment, the handle base 11 is also provided with a fourth magnet 117. The fourth magnet 117 can attract the end of the second rotating latch 211 near the first engaging portion 111 to press against the handle base 11, thereby further improving the engagement stability of the second slot 116 and the second rotating latch 211. The fourth magnet 117 can also be provided in the mounting portion 21, in which case the fourth magnet 117 is located at the end of the second rotating latch 211 away from the first engaging portion 111, thereby ensuring a stable engagement between the second rotating latch 211 and the second slot 116.

[0128] Please refer to it again. Figures 14 to 17 In this embodiment, during the installation process, the user only needs to bring the handle base 11 close to the mounting part 21. Under the mutual attraction of the first magnet 213 and the second magnet 113, and by utilizing the magnetic force of the two to minimize system energy, the handle base 11 is driven to move along the axial direction of the kettle body 2, so that the first locking part 111 automatically engages with the first slot 217. When the first locking part 111 and the first slot 217 are engaged, one end of the second rotating buckle 211 automatically engages with the second slot 116. Therefore, in this solution, the user does not need to manually engage the handle base 11 and the mounting part 21, thus facilitating the quick installation of the handle 1. Under the action of the first elastic member 2111, the second rotating buckle 211 is secured to the second slot 116. When it is necessary to remove the handle 1, simply insert the unlocking part 1181 through the unlocking hole 118 and push the second rotating buckle to rotate in the opposite direction, so that the end of the second rotating buckle 211 away from the first locking part 111 disengages from the second slot 116.

[0129] In an embodiment of the present invention, please refer to Figures 18 to 41The handle 12 is rotatably mounted on the handle base 11, and there are two handles 12; the two handles 12 have a use position, in which the sides of the two handles 12 that are close to each other abut against each other; the two handles 12 rotate in opposite directions to switch to the storage position.

[0130] Specifically, the handle 12 is rotatably mounted on the handle base 11, allowing it to rotate relative to the handle base 11, and thus relative to the kettle body 2. In the use position, the two handles 12 abut against each other on their closest sides, forming a single unit for the user to grip. At this position, the two handles 12 are angled to the kettle body 2, meaning the handles 12 and the kettle body 2 form an angle at their mounting points, facilitating a comfortable grip. Optionally, the angle between the two handles 12 and the kettle body 2 can be 90°, or less than 90°, or greater than 90°. In the storage position, the opposite sides of the two handles 12 can abut against the kettle body 2, reducing the axial dimension of the thermos and minimizing the space occupied by the handles 12; alternatively, the distance from the two handles 12 to the outer surface of the kettle body 2 can be a preset distance, such as less than or equal to 10mm. In other words, when it is necessary to store the thermos, users can flexibly choose to switch the handle 12 to the storage position, or directly remove the handle 1.

[0131] Furthermore, an elastic limiting structure 13 is provided between the handle portion 12 and the handle seat 11;

[0132] In the usage position, the elastic limiting structure 13 causes the two handle portions 12 to abut against each other on their adjacent sides; in the storage position, the elastic limiting structure 13 causes the two handle portions 12 to abut against the body 2 on their opposing sides. Specifically, the elastic limiting structure 13 allows the handle portions 12 to abut against the body 2, thereby ensuring that the handle portions 12 are stably in the storage state, facilitating the storage of the thermos; the elastic limiting structure 13 also allows the two handle portions 12 to abut against each other on their adjacent sides, thereby ensuring the connection stability of the two handle portions 12 during use, for user convenience. In other embodiments, each of the two handle portions 12 is provided with a magnetic suction member 125 on its adjacent side. In the usage position, the two magnetic suction members 125 are magnetically connected, thereby 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, and 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.

[0133] 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 against the outer circumference of the pot body 2 at the storage location, thereby further improving storage stability and reducing the possibility of handle 12 failure due to compression during storage.

[0134] Please see Figures 18 to 27 In one embodiment, the elastic pivot 131 assembly includes a pivot 131, a first limiting member 132, a second limiting member 133, and a second elastic member 134 sleeved on the pivot 131. One end of the handle seat 11 is provided with a first pivot hole 1101, and the pivot 131 is installed in the first pivot hole 1101. The first limiting member 132 can move axially along the first pivot hole 1101. The second limiting member 133 connects the pivot 131 and the handle portion 12. The first limiting member 132 faces the second limiting member. A first limiting protrusion 1321 is provided on one side of the 133, 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 that is adapted to the first limiting groove 1322 and a second limiting groove 1332 that is adapted to the first limiting protrusion 1321. The second 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.

[0135] At the storage position, the first limiting protrusion 1321 extends into a second limiting groove 1332, and the second 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 kettle body 2.

[0136] In the usage position, the first limiting protrusion 1321 extends into another second limiting groove 1332, and the second elastic member 134 causes the first limiting protrusion 1321 to press against the second limiting member 133, so that the two handle portions 12 are close to each other and abut against each other.

[0137] Specifically, the rotating shaft 131 is rotatably installed within the first rotating shaft hole 1101. Therefore, to reduce the likelihood of the rotating shaft 131 dislodging from the first rotating shaft hole 1101, in this design, one of the inner wall of the first rotating shaft hole 1101 and the circumferential direction of the rotating shaft 131 is provided with an annular retaining protrusion 1111, and the other is provided with an annular retaining groove 1103. The annular retaining protrusion 1111 can be slidably installed in the annular retaining groove 1103. 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 1101, thereby allowing the first rotating shaft hole 1101 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 1101. For example, a limiting surface is provided on the circumference of the first rotating shaft hole 1101, and the limiting surface restricts the rotation of the first limiting member 132 within the first rotating shaft hole 1101. That is, at least a portion of the cross-section of the first pivot hole 1101 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 1101 can be polygonal, and the cross-section of the corresponding first limiting member 132 is also polygonal.

[0138] One end of the second elastic member 134 abuts against the side of the first limiting member 132 opposite to the second limiting member 133, and the other end abuts against the wall of the first rotating shaft hole 1101. The second 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. This allows the first limiting member 132 and the second limiting member 133 to interact, so that the first limiting member 132 can move along the axial direction of the first rotating shaft hole 1101. This allows the first limiting member 132 and the second limiting member 133 to jointly adjust the length of the second elastic member 134, thereby adjusting the elastic potential energy of the second elastic member 134.

[0139] 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 second elastic member 134 is at its maximum, and the elastic potential energy of the second elastic member 134 is at its minimum (possibly approaching zero). The pressing force of the second 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 second elastic member 1321... When the length of 34 is at its maximum, the elastic potential energy of the second elastic member 134 is at its maximum, and the pressing force of the second elastic member 134 on the first limiting member 132 is also at its maximum. Let this position be the middle position of the handle 12, which is usually located between the storage position and the use position. When the second limiting member 133 continues to rotate relative to the first limiting member 132 from the middle position, the first limiting protrusion 1321 slides toward the second limiting groove 1332. Correspondingly, the second limiting protrusion 1331 slides toward and into 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 second elastic member 134 is partially compressed, and the second elastic member 134 has a certain clamping force on the first limiting member 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 member 132 can make the second limiting member 133 have the tendency to continue to rotate, so that the handle part 12 also has the tendency to continue to rotate.

[0140] Therefore, in the storage position, the first limiting protrusion 1321 partially extends into a second limiting groove 1332, thereby using the second 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 kettle body 2; in the use position, the first limiting protrusion 1321 partially extends into another second limiting groove 1332, thereby using the second 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.

[0141] 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 to make the handle part 12 automatically move 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 automatically move 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.

[0142] Furthermore, the side of the first limiting protrusion 1321 has a fifth guide surface 1323, which causes the first limiting protrusion 1321 to taper in the direction close to the second limiting member 133. In this solution, due to the presence of the fifth guide surface 1323, the first limiting protrusion 1321 has an approximately triangular structure, thereby guiding the movement of the handle 1 from the middle position to the storage position and the use position, facilitating the switching of the handle 12 to different positions. Of course, in other embodiments, the first limiting protrusion 1321 can also be roughly trapezoidal or semi-circular.

[0143] In this configuration, the intermediate position can be exactly 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, this intermediate position may not be located between the storage position and the use position.

[0144] 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 kettle body 2, which is not conducive to the service life of the kettle 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 21 , Figure 24 and Figure 25 The handle portion 12 includes a first rotating end 121 and a second rotating end 122. The first rotating end 121 is rotatably mounted on 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 1102, and the hole wall of the second rotating shaft hole 1102 is provided with an arc-shaped groove 1103. A limiting protrusion 1221 is protruding from the side of the second rotating end 122. The second rotating end 122 is rotatably mounted on the second rotating shaft hole 1102, and the limiting protrusion 1221 is slidably engaged with the arc-shaped groove 1103. In the storage position, the limiting protrusion... 1221 abuts against one end of the arc-shaped groove 1103, thereby limiting the handle 12 and reducing the possibility of the handle 1 colliding with the kettle body 2; in the use position, the limiting protrusion 1221 abuts against the other end of the arc-shaped groove 1103, 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 1103, thereby allowing the arc-shaped grooves 1103 to further guide the rotation of the handle 12.

[0145] Please see Figure 28 , Figure 29 and Figure 37In another embodiment of the present invention, 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 1104. 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 1104. In the storage position, the third limiting protrusion 1241 abuts against one end of the arc-shaped limiting hole section 1104. In the use position, the third limiting protrusion 1241 abuts against the other end of the arc-shaped limiting hole section 1104. 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 1104, 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 1104, thereby providing support for the handle part 12. The third limiting protrusion 1241 abuts against the other end of the arc-shaped limiting hole section 1104 in the used 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 used position, the third limiting protrusion 1241 slides within the arc-shaped limiting hole section 1104, thereby enabling the arc-shaped limiting hole section 1104 to further guide the rotation of the handle 12.

[0146] Understandably, the cooperation between the third limiting protrusion 1241 and the arc-shaped limiting hole segment 1104 is similar to the cooperation between the limiting card protrusion 1221 and the arc-shaped card groove 1103. 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 1104 and the cooperation between the limiting card protrusion 1221 and the arc-shaped card groove 1103 can be set selectively.

[0147] For further details, please refer to Figures 28 to 35 The elastic limiting structure 13 includes a third elastic element 135, with its two ends respectively connected to two third limiting protrusions 1241. The third limiting protrusions 1241 are rotatable about the rotating part 124 to adjust the length of the third elastic element 135. In the storage position, the third limiting protrusions 1241 rotate to the side of the rotating part 124 away from the kettle body 2. In the use position, the third limiting protrusions 1241 rotate to the side of the rotating part 124 close to the kettle body 2.

[0148] 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 the two rotating parts 124 are close together, the distance between the two third limiting parts is the shortest, corresponding to the shortest length of the third elastic element 135 and the minimum elastic potential energy of the third elastic element 135, which is set as the first extreme position; when the two third limiting protrusions 1241 rotate to the side where the two rotating parts 124 are opposite to each other, the distance between the two third limiting parts is the farthest, corresponding to the longest length of the third elastic element 135, and the minimum elastic potential energy of the third elastic element 135. The elastic potential energy of component 135 is at its maximum, and it is set as the second limit position (corresponding to the middle position of 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 away from the pot body 2 or to the side facing the pot body 2, under the pulling force of the third elastic component 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 pot body 2; and in the use position, the two handles 12 press against each other.

[0149] 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 pot body 2. This does not mean that the third limiting protrusion 1241 is completely located on the side of the rotating part 124 away from the pot body 2. In other words, the third limiting protrusion 1241 is not located in the radial direction of the pot body 2. It can form a certain angle with the radial direction of the pot body 2. That is, the storage position is not completely located in the middle of the first and second extreme positions. It can be set according to the actual rotation angle of the handle part 12. In the use position, the third limiting protrusion 1241 rotates to the side of the rotating part 124 close to the pot body 2. This does not mean that the third limiting protrusion 1241 is completely located on the side of the rotating part 124 away from the pot body 2. In other words, the third limiting protrusion 1241 is not directly opposite the pot body 2. It can form a certain angle with the radial direction of the pot body 2. That is, the use position is not completely located in the middle of the first and second extreme positions. It can be set according to the actual rotation angle of the handle part 12. In this design, the angle of the arc-shaped limiting hole segment 1104 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 1104 is 240°.

[0150] To facilitate the installation of the third elastic element 135, hooks are provided at both ends of the third elastic element 135, and the two hooks are respectively attached to the two third limiting protrusions 1241. In one embodiment, the third elastic element 135 is configured as a tension spring. Due to the middle position, the third limiting protrusion 1241 rotates to the side opposite to the two rotating parts 124, at which point the elastic potential energy of the third elastic element 135 is at its maximum. Under the elastic action of the third 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.

[0151] Please see Figures 36 to 41 In another embodiment of the present invention, the elastic limiting structure 13 includes a limiting spring 136, the limiting spring 136 being disposed on the side of the rotating part 124 near the kettle body 2, and limiting flats 1242 being provided on 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.

[0152] 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 both 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 it in the use position. The two limiting flat parts 1242 can be arranged parallel to each other or at a certain angle, allowing designers to design them according to the required rotation angle of the handle 12.

[0153] Furthermore, when 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.

[0154] 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 1104, 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 1104 can also be replaced by the engagement structure of the limiting locking protrusion 1221 and the arc-shaped locking groove 1103. The limiting spring 136 can be fixed to the handle seat 11 by fasteners such as screws and bolts.

[0155] To ensure that the two handles 12 can move in the same direction, in one embodiment, please refer to... Figures 42 to 44 A gear set 14 is provided between the two handle portions 12, which enables the two handle portions 12 to rotate simultaneously towards or away from each other. Specifically, in this design, the two handle portions 12 are driven by four sequentially arranged gears 141 meshing together. The two outer gears 141 are located in the rotating part 124 and can rotate with the handle portion 12. The two inner gears 141 are rotatably mounted on the handle portion 12, so that when the user rotates one of the two handle portions 12, the other can rotate accordingly. The number of gears 141 in the gear set 14 can be less than four, such as two; or more than four, such as six or eight, but the number of gears 141 is always an even number.
