Description

Technical Field

[0001] This invention belongs to the technical field of milk shaking and milk warming products, specifically relating to a milk warmer with a milk shaking function. Background Technology

[0002] In the prior art, Chinese utility model patent CN213129177U, published on May 7, 2021, discloses a multifunctional bottle warmer, which includes a base with a heating chamber for holding a container, multiple nozzles distributed on the wall of the heating chamber, a circulating vortex channel surrounding the heating chamber, and a hot air mechanism disposed in the base for providing hot air. The multiple nozzles are connected to the circulating vortex channel, and the hot air mechanism is connected to the circulating vortex channel. The arrangement of the multiple nozzles and the circulating vortex channel can uniformly process the container in the heating chamber. In practical applications, this type of bottle warmer has good uniform heating and heat preservation effects.

[0003] Currently, consumers' needs for bottle warmers are no longer limited to heating and keeping bottles warm. Adding a shaking function to bottle warmers would further facilitate their use. After adding the shaking function, the part of the bottle warmer base used to hold the container (hereinafter referred to as the holding part) needs to be structurally improved to facilitate shaking (such as rotation and swaying). A shaking drive device connected to the holding part should be added so that the holding part can simultaneously realize the shaking function while maintaining communication with the hot air mechanism. However, the structural improvement of the holding part and the addition of the shaking drive device will affect the flow of hot air in the base. In order to guide the flow of hot air in the base and to avoid the hot air affecting the operation of electrical components in the base, it is necessary to improve the structure of the bottle warmer, especially the air duct structure.

[0004] In addition, air bottle warmers with a shaking function drive the shaking cup directly by connecting the motor and the shaking cup coaxially (hereinafter referred to as direct drive structure), or by connecting the motor to the shaking cup through a gear assembly or belt assembly (hereinafter referred to as indirect structure).

[0005] The common problems with current direct-drive and indirect-drive structures are: 1. The structures of both direct-drive and indirect-drive are unreasonable, resulting in high noise and poor stability; 2. Because the direct-drive and indirect-drive structures do not consider or configure the structure and location for installing temperature sensors, they cannot achieve precise temperature control of the bottle shaker; 3. Because the direct-drive and indirect-drive structures adopt an integral installation method and do not use modular design, installation and maintenance are difficult. Therefore, it is necessary to improve the transmission device of the air bottle warmer.

[0006] Additionally, Chinese Patent Document No. CN217852573U, published on November 22, 2022, discloses a baby shaker, which includes a housing, a baby bottle shaking bucket and a shaking bucket driving device inside the housing. The top of the baby bottle shaking bucket has a baby bottle inlet, which is exposed on the top of the housing. The shaking bucket driving device is connected to the shaking bucket and drives the baby bottle shaking bucket to shake inside the housing. The baby bottle shaking bucket includes a bucket body and a flexible cylinder. The upper end of the flexible cylinder is open and fixedly connected to the top of the housing. The lower end of the flexible cylinder is fixedly connected to and communicates with the top of the bucket body. A baby bottle fixing frame is provided inside the baby bottle shaking bucket, and multiple elastic locking claws are arranged at intervals along the circumference on the inner side wall of the baby bottle fixing frame.

[0007] The elastic clamping claw (equivalent to an elastic clamping element) is used to press firmly against the side of the bottle to achieve bottle positioning, as shown in the accompanying drawings of this document and the prior art schematic diagram of this application. Figure 21 and 22 As shown, the thickness of the entire elastic clamping claw remains constant, making it difficult for the distal end of the elastic clamping claw (the part that contacts the bottle) to rotate and deform. The distal end of the elastic clamping claw has a weak ability to adapt to the shape of the side of the bottle, resulting in only point contact between the elastic clamping claw and the bottle. This is not conducive to the clamping effect of the elastic clamping claw on the bottle and has certain limitations. Therefore, further improvement is needed. Summary of the Invention

The transmission device can be used as a separate module accessory, making it easy to adapt to different bottle warmer products.

[0046] 3. The first joint, first thinning structure, and first thinning position of the elastic clamping element reduce the difficulty of the elastic clamping element and enable it to adapt to changes in the size of the baby bottle. The second joint adopts a thinning design, and the thickness at the second thinning position of the second joint is small, making it easier for the clamping part of the elastic clamping element to rotate and deform. When the baby bottle is placed in the clamping cavity, the second joint with the second thinning structure and second thinning position enables the elastic clamping element to better adapt to changes in the shape of the baby bottle, so that the clamping part and the baby bottle can form a surface contact, which is beneficial to the stable clamping effect of the elastic clamping element on the baby bottle.

[0069] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0070] like Figure 1-6 As shown, a bottle warmer with a shaking function includes a main unit 3, a shaking heating cup 1 for holding a baby bottle 4, a transmission device 52 connected to the shaking heating cup 1, a power device 51 connected to the transmission device 52, a first air duct assembly 6 that communicates with the inside of the shaking heating cup 1 and is located on the periphery of the shaking heating cup 1, and a hot air device 7 that is connected to the first air duct assembly 6 and delivers hot air into the shaking heating cup 1 through the first air duct assembly 6. The baby bottle 4 can also be replaced with other bottles or cups. When the user places the baby bottle 4 into the shaking heating cup 1, the power device 51 drives the shaking operation of the shaking heating cup 1 through the transmission device 52. When the hot air device 7 operates, it delivers hot air into the shaking heating cup 1 and is used to heat and keep the baby bottle 4 inside the shaking heating cup 1 warm.

[0071] The first air duct assembly 6 is annular with an annular air outlet 63 in the center. The annular air outlet 63 of the first air duct assembly 6 is designed to evenly distribute hot air to the milk warmer cup 1. The lower part of the milk warmer cup 1 has an air inlet 101 that communicates with the annular air outlet 63 and is distributed along the annular shape. The first air duct assembly 6 can deliver hot air into the milk warmer cup 1 in a circumferential direction, which is beneficial for the even heating and heat preservation of the milk bottle 4 inside the milk warmer cup 1. While the first air duct assembly 6 is connected to the inside of the milk warmer cup 1, it also allows the milk warmer cup 1 to be shaken relative to the first air duct assembly 6. For milk operation, a gap needs to be left between the first air duct assembly 6 and the milk heating cup 1 for the operation of the milk heating cup 1. Specifically, there is an active gap section 32 between the first air duct assembly 6 and the milk heating cup 1 that communicates with the inside of the main unit 3. The active gap section 32 is a passively designed structure. The setting of the active gap section 32 ensures that the first air duct assembly 6 will not obstruct the milk shaking operation of the milk heating cup 1, and the milk heating cup 1 can shake relative to the first air duct assembly 6. The active gap section 32 is located between the annular air outlet 63 and the air inlet 101.

[0072] The main unit 3 is equipped with a second air duct assembly 9, which connects the movable gap section 32 and the hot air device 7 and guides the cold air entering from outside the main unit 3 and the hot air entering the main unit 3 from the movable gap section 32 to the input end of the hot air device 7. The hot air generated by the hot air device 7 during operation is delivered to the milk warmer cup 1 through the first air duct assembly 6. Due to the existence of the movable gap section 32, some hot air will enter the main unit 3 through the movable gap section 32. The second air duct assembly 9 is set to guide the cold air entering from outside the main unit 3 and the hot air entering the main unit 3 from the movable gap section 32 to the input end of the hot air device 7, reducing the impact of hot air on the electrical components (specifically the power device 51 and the control device 10) located inside the main unit 3. At the same time, the second air duct assembly 9 enables the milk warmer to reuse the hot air entering the main unit 3 through the movable gap section 32, which can realize the partial recycling of hot air, achieve the effect of energy saving, and help improve the energy utilization efficiency.

[0073] In some embodiments of the invention, a temperature sensor assembly 33 is provided inside the transmission device 52. The second air duct assembly 9 guides the cold air entering from outside the main unit 3 and can cool the temperature sensor assembly 33. The temperature sensor assembly 33 extends upward into the milk heating cup 1 and comes into contact with the bottom of the milk bottle 4. The temperature sensor assembly 33 is used to detect the temperature of the milk bottle 4 and transmit the corresponding temperature signal to the control device 10.

[0074] In some embodiments of the invention, the second air duct assembly 9 is located below the first air duct assembly 6, and the transmission device 52 is located inside the second air duct assembly 9. The second air duct assembly 9 guides cold air entering from outside the main unit 3 to cool the transmission device 52.

[0075] The second air duct assembly 9 is provided with an air outlet 96 and an air inlet 97 that communicates with the outside of the main unit 3. The air outlet 96 and the air inlet 97 are located on both sides of the transmission device 52 and are arranged opposite to each other. The cold air entering from the outside of the main unit 3 guided by the second air duct assembly 9 will inevitably pass through the transmission device 52, which is beneficial to the cooling of the transmission device 52.

[0076] The main unit 3 is provided with ventilation openings 31 that are connected to the outside of the main unit 3 and the hot air device 7 respectively, such as Figure 6 As shown, air inlet 97 and vent 31 are the same opening, or, as... Figure 1 As shown, air inlet 97 and ventilation outlet 31 are two different openings.

[0077] In some embodiments of the invention, the milk-shaking heating cup 1 is located above the transmission device 52, and the power device 51 is located above or below the transmission device 52, such as... Figure 4 , 5 As shown, the power unit 51 is located below the transmission unit 52, as... Figure 13 As shown, the power unit 51 is located above the transmission unit 52; as Figure 1 , 2 As shown in Figures 4 and 5, the transmission device 52 and the temperature sensor assembly 33 are located inside the second air duct assembly 9;

[0078] like Figure 1 , 2 As shown in Figure 5, the hot air device 7 includes a fan 71 and a heater 72, both of which are connected to the first air duct assembly 6. When the fan 71 is running, it drives the air flow, and when the heater 72 is running, it heats the air. The heater 72 is located inside the first air duct assembly 6, and the fan 71 is connected to the input end of the first air duct assembly 6.

[0079] like Figure 1-5 As shown, the fan 71 is vertically arranged, or, as... Figure 6 As shown, the fan 71 is arranged horizontally;

[0080] like Figure 2 , 4As shown in Figure 5, the host 3 is provided with a control device 10. The control device 10 may include a circuit board disposed inside the host 3 and a control board electrically connected to the circuit board and located on the outside of the circuit board. The control board is located on the side of the host 3. The fan 71 and heater 72 of the hot air device 7, the power device 51, and the temperature sensor assembly 33 are electrically connected to the control device 10 respectively. The power device 51 includes a motor, which is electrically connected to the control device 10. The output shaft of the motor is connected to the transmission device 52.

[0081] In some embodiments of the invention, the movable gap interval 32 includes an upper gap interval located above the annular air outlet 63 and a lower gap interval located below the annular air outlet 63. The annular air outlet 63 and the air inlet 101 are located between the upper gap interval and the lower gap interval and are interconnected. The upper gap interval is connected to the outside of the main unit 3. The upper gap interval includes a channel 36 formed by the inner side wall of the main unit 3 and the milk heating cup 1. The channel 36 is connected to the outside of the main unit 3. The lower gap interval is connected to the second air duct assembly 9. The hot air in the movable gap interval 32 does not flow completely into the interior of the main unit 3, which at least helps to reduce the accumulation of hot air inside the main unit 3.

[0082] There are several air inlets 101 arranged circumferentially on the side of the milk heating cup 1. Hot air can enter the milk heating cup 1 through multiple air inlets 101, which is conducive to the uniform heating of the milk bottle 4 inside the milk heating cup 1.

[0083] like Figure 1-6 As shown, the first air duct assembly 6 includes an annular portion 61 and an air inlet portion 62 connected to the annular portion 61. The annular portion 61 is arranged around the outside of the milk heating cup 1, and the annular air outlet 63 is arranged inside the annular portion 61. The movable gap interval 32 is located between the annular portion 61 and the milk heating cup 1. The hot air device 7 is connected to the air inlet portion 62.

[0084] In some embodiments of the invention, such as Figure 7-13As shown, the transmission device 52 includes an input component A and an output component B connected to the input component A via a transmission belt C. The output component B includes an output base B1, a first bearing B2 and a second bearing B3 arranged vertically on the output base B1, and a rotating sleeve B4 fitted around the first bearing B2 and the second bearing B3. The first bearing B2 and the second bearing B3 can be ball bearings. The output component B of the transmission device 52 adopts a two-bearing structure (specifically, the first bearing B2 and the second bearing B3), with the two bearings arranged vertically between them. This structure helps to improve the stability of the rotating sleeve B4 during operation. The milk heating cup 1 is fixed to the rotating sleeve B4. The output end of the power device 51 is connected to the input end of the input component A. The transmission belt C is wound around the rotating sleeve B4 and located on the first bearing. Between bearing B2 and bearing B3, when the input component A is running, it drives the rotating sleeve B4 of the output component B to rotate via the transmission belt C. The force exerted by the transmission belt C on the rotating sleeve B4 is located between the two bearings, which also helps to improve the stability of the rotating sleeve B4 during operation, thereby improving the transmission stability of the transmission device and reducing the noise during operation of the transmission device. The inner side of the output base B1 is provided with a first mounting hole B13, and the temperature sensor component 33 is disposed in the first mounting hole B13. The first mounting hole B13 is provided with a spring E1 located at the lower part of the temperature sensor component 33. The main unit 3 is provided with a positioning platform for supporting the bottom of the spring E1. The positioning platform is provided with a column for mounting the spring E1. The first mounting hole B13 passes through the upper part of the output base B1, and the temperature sensor component 33 protrudes upward from the output base B1.

[0085] like Figure 7-9 As shown, the power unit 51 is located below the input component A. When the power unit 51 is running, it drives the input component A to run, and the input component A drives the rotating sleeve B4 of the output component B to rotate via the transmission belt C; of course, as... Figure 13 As shown, due to the limitations of the installation location, the power unit 51 can also be installed on the upper part of the input component A.

[0086] In some embodiments of the invention, the transmission belt C is located in the middle, upper middle, or lower middle part between the first bearing B2 and the second bearing B3, such as... Figure 7 As shown, the transmission belt C is located in the middle between the first bearing B2 and the second bearing B3. The force exerted by the transmission belt C on the rotating sleeve B4 is located in the middle position between the two bearings, which is beneficial to improving the stability of the rotating sleeve B4 during operation.

[0087] like Figure 7 , 11As shown in Figure 12, the rotating sleeve B4 is provided with a first limiting structure for positioning the first bearing B2 and the second bearing B3. The first limiting structure includes a first limiting platform B41 disposed inside the rotating sleeve B4 and located between the first bearing B2 and the second bearing B3, and a first protrusion B42 disposed inside the rotating sleeve B4 and located at the bottom of the second bearing B3. The first protrusion B42 prevents the second bearing B3 from falling downward. When the second bearing B3 is installed inside the rotating sleeve B4, the second bearing B3 is limited between the first protrusion B42 and the first limiting platform B41 after passing the first protrusion B42. The first bearing B2 is directly embedded in the rotating sleeve B4 and placed on the first limiting platform B41.

[0088] like Figure 7 , 10 As shown in Figure 12, the output base B1 is provided with a second limiting structure for positioning the second bearing B3. The second limiting structure includes a second limiting platform B11 disposed on the side of the output base B1 and disposed at the bottom of the second bearing B3, and a second protrusion B12 disposed on the side of the output base B1 and disposed against the upper part of the second bearing B3. The second limiting platform B11 is used to support the second bearing B3. When the second bearing B3 is fitted on the output base B1, the second bearing B3 is limited between the second protrusion B12 and the second limiting platform B11 after passing the second protrusion B12.

[0089] like Figure 7 , 11 As shown in Figure 12, the rotating sleeve B4 has a first mounting groove B43 for winding the transmission belt C on its side, and a mounting platform B44 is provided on the outer side of the rotating sleeve B4. The milk heating cup 1 is fixed to the mounting platform B44, and the transmission belt C is located below the mounting platform B44. The mounting platform B44 can be connected to the milk heating cup 1 by fasteners.

[0090] In some embodiments of the invention, such as Figure 7-10 As shown, the input component A includes an input base A1, an input shaft A2 disposed on the input base A1, and a third bearing A3 disposed between the input base A1 and the input shaft A2. The input shaft A2 is used to connect to the output end of the power device 51. The transmission belt C is wound around the input shaft A2. When the input shaft A2 rotates, the rotating sleeve B4 is driven to rotate through the transmission belt C.

[0091] like Figure 7 , 10As shown, the input base A1 is provided with a third limiting structure for positioning the third bearing A3. The third limiting structure includes a support platform A11 disposed inside the input base A1 and disposed at the bottom of the third bearing A3, and a third protrusion A12 disposed inside the input base A1 and disposed at the top of the third bearing A3. When the third bearing A3 is installed in the input base A1, the third bearing A3 is limited between the third protrusion A12 and the support platform A11 after passing the third protrusion A12.

[0092] like Figure 7-10 As shown, the input shaft A2 has a wheel A21 on its side, which is located above the input base A1. The input shaft A2 has a coupling structure at its end, which is used to connect to the output end of the power device 51. Specifically, the coupling structure includes an input coupling located at the end of the input shaft A2, which is used to connect to the output end of the power device 51 (specifically, the motor output end of the power device 51 has an output coupling, which is connected to the input coupling of the input shaft A2). The wheel A21 has a second mounting groove A22 on its side for winding the transmission belt C. The input base A1 has a second mounting hole A13 penetrating its upper and lower parts. Figure 7-9 As shown, the power unit 51 is located below the input component A, and the coupling structure is located at the lower end of the input shaft A2. The output end of the power unit 51 extends into the second mounting hole A13 and is connected to the coupling structure of the input shaft A2; of course, as... Figure 13 As shown, due to the limitation of the installation position, the power unit 51 can also be set on the upper part of the input component A, and the coupling structure is located at the upper end of the input shaft A2;

[0093] like Figure 7-10 and Figure 12 As shown, the transmission device 52 includes a base plate D, an input component A and an output component B, both of which are disposed on the base plate D. The output base B1 is connected to the base plate D, the input base A1 is connected to the base plate D, and the power device 51 is disposed on the base plate D. The transmission device 52 can be used as a separate module accessory, which makes it easy to adapt the transmission device 52 to different air bottle warmer products. At the same time, it makes the installation and maintenance of the transmission device 52 easier. The base plate D, the output base B1 and the input base A1 are integrally formed, and the base plate D, the output base B1 and the input base A1 constitute a single part, which helps to reduce the number of parts in the transmission device 52.

[0094] like Figure 7-10 and Figure 12 As shown, the upper part of the substrate D is provided with a first mounting post D1 located outside the input component A and the output component B. The first mounting post D1 is connected to the inner top of the host 3 by fasteners.

[0095] In some embodiments of the invention, such as Figure 14-20As shown, the inner side of the milk heating cup 1 is provided with a clamping cavity 11 for holding the milk bottle 4. An elastic clamping element 2 is connected to the inner side of the milk heating cup 1. The elastic clamping element 2 includes a first joint 24 and a clamping part 23 for contacting the milk bottle 4, which are connected in sequence on the inner side of the milk heating cup 1. The first joint 24 reduces the difficulty of deformation of the elastic clamping element 2, so that the elastic clamping element 2 can adapt to the change in the size of the milk bottle 4.

[0096] like Figure 15-19 As shown, the elastic clamping element 2 also includes a second joint 22 located between the first joint 24 and the clamping part 23. The second joint 22 is provided with a second thinning structure for reducing the thickness of the second joint 22 and forming a second thinning position 220 on the second joint 22. The second joint 22 adopts a thinning design, and the thickness at the second thinning position 220 of the second joint 22 is small, making it easier for the distal end of the elastic clamping element 2 (i.e., the clamping part 23) to rotate and deform (specifically, swing down or tilt up). When the baby bottle 4 is placed in the clamping cavity 11, the second joint 22 with the second thinning structure and the second thinning position 220 enables the elastic clamping element 2 to better adapt to the changes in the shape of the baby bottle 4, so that the clamping part 23 and the baby bottle 4 can form a surface contact, which is beneficial to the stable clamping effect of the elastic clamping element 2 on the baby bottle 4. The structure includes a second thinning groove 221 disposed on the second joint portion 22. The second thinning groove 221 is disposed to reduce the thickness of the second joint portion 22, so that the elastic clamping element 2 can better adapt to the shape changes of the bottle 4. The second thinning groove 221 is located on the side of the second joint portion 22 opposite to the bottle 4, so as to prevent the second thinning groove 221 from being exposed on the surface of the second joint portion 22 opposite to the bottle 4. The two ends of the second thinning groove 221 respectively penetrate the two ends of the second joint portion 22, so that the second thinning position 220 is easy to deform. The thickness of the second thinning position 220 is less than the thickness of the first joint portion 24. Compared with the first joint portion 24, the second joint portion 22 is more easy to deform. The second joint portion 22 enables the elastic clamping element 2 to better adapt to the local shape changes of the bottle 4, so that the clamping part 23 and the bottle 4 can form a surface contact.

[0097] The elastic clamping element 2 also includes an arm 21 connected between a first joint 24 and a second joint 22. The first joint 24 serves as a transition connection between the arm 21 and the milk warmer cup 1, and the second joint 22 serves as a transition connection between the arm 21 and the clamping part 23. The thickness of the second thinning position 220 is less than the thickness of the arm 21, and / or the thickness of the second thinning position 220 is less than the thickness of the clamping part 23. Figure 18 and 19 As shown, the thickness of the second thinning position 220 is less than the thickness of the arm portion 21 and the clamping portion 23, respectively; as Figure 15-19As shown, the first joint 24, arm 21, second joint 22, and clamping part 23 are connected sequentially from top to bottom. The arm 21 extends obliquely downward toward the center of the milk warming cup 1, and the clamping part 23 extends obliquely downward toward the center of the milk warming cup 1, so that the milk bottle 4 can be placed in the clamping cavity 11 from top to bottom. Figure 20 As shown, under natural, unforced conditions, the angle θ1 between the arm 21 and the central axis of the milk heating cup 1 is greater than or equal to the angle θ2 between the clamping part 23 and the central axis of the milk heating cup 1. The second joint 22 is arc-shaped and protrudes towards the center of the milk heating cup 1. The elastic clamping element 2 is generally thin-plate shaped, and the thin-plate elastic clamping element 2 is easy to undergo elastic deformation.

[0098] The number of elastic clamping elements 2 is two or more, and the two or more sets of elastic clamping elements 2 are arranged at intervals along the circumference, such as... Figure 14-17 As shown, the number of elastic clamping elements 2 is four sets, which are evenly distributed along the circumferential direction;

[0099] like Figure 16 and 17 As shown, the elastic clamping element 2 is provided with a forked groove 25 so that the clamping part 23 forms sub-clamping parts located on both sides of the forked groove 25. The sub-clamping parts are equivalent to fingers. The sub-clamping parts on both sides of the forked groove 25 can be deformed and adjusted according to the shape of the side of the bottle 4. The sub-clamping parts formed after the clamping part 23 forks can better contact the side of the bottle 4. The forked groove 25 is provided on the clamping part 23. The number of forked grooves 25 is one set, or the number of forked grooves 25 is two or more sets, and the two or more sets of forked grooves 25 are arranged at intervals in the lateral direction. The forked groove 25 extends to the second joint 22. The second joint 22 on both sides of the forked groove 25 can be deformed and adjusted according to the shape of the side of the bottle 4 so that the sub-clamping parts can better contact the side of the bottle 4; or, as Figure 3 and 4 As shown, the bifurcation groove 25 extends to the second joint portion 22 and the arm portion 21. The second joint portion 22 on both sides of the bifurcation groove 25 and the arm portion 21 on both sides of the bifurcation groove 25 can be deformed and adjusted according to the shape of the side of the bottle 4, so that the clamping part can make better surface contact with the side of the bottle 4.

[0100] In some embodiments of the invention, such as Figure 14-17 As shown, the milk heating cup 1 includes a cup body 12 and a clamping sleeve 13 disposed on the cup body 12. The side of the clamping sleeve 13 is inserted into the inner side of the cup body 12. The milk heating cup 1 adopts a two-part structure of cup body 12 and clamping sleeve 13, which facilitates the production and processing of the milk heating cup 1. The elastic clamping element 2 is disposed on the inner side of the clamping sleeve 13. The cup body 12 is connected to the output end of the transmission device 52, specifically, the cup body 12 is fixedly connected to the mounting platform B44 of the rotating sleeve B4.

[0101] like Figure 15-17 As shown, the clamping sleeve 13 is provided with a window portion opposite to the elastic clamping element 2 and a linkage plate 14 connected to the window portion for abutting against the inner wall of the cup body 12. The elastic clamping element 2 is disposed inside the linkage plate 14, and the first joint portion 24 is connected to the linkage plate 14. Since the clamping sleeve 13 is connected to the cup body 12, there is an installation gap between the cup body 12 and the clamping sleeve 13. When the milk heating cup 1 rotates as a whole, the clamping sleeve 13 is prone to shaking, resulting in instability when the clamping sleeve 13 moves. After the linkage plate 14 is provided on the clamping sleeve 13, when the milk bottle 4 is placed on the milk heating cup 1, it pushes the elastic clamping element 2 outward, causing the linkage plate 14 to move towards the side of the cup body 12. The linkage plate 14 is close to the side of the cup body 12, which helps to improve the stability of the clamping sleeve 13 when it operates. The side and bottom of the linkage plate 14 are provided with a partition groove 15 between the window portion and the window portion. The partition groove 15 allows the linkage plate 14 to deform.

[0102] A horizontal positioning structure and a vertical positioning structure are provided between the cup body 12 and the clamping sleeve 13. These structures facilitate the installation and removal of the clamping sleeve 13 from the cup body 12. The clamping sleeve 13 is detachably mounted on the cup body 12. The horizontal positioning structure includes a slot 17 located on one of the cup body 12 and the clamping sleeve 13, and an insert 16 located on the other of the cup body 12 and the clamping sleeve 13 and engaging with the slot 17. The slot 17 and the insert 16 are located between the opposite sides of the cup body 12 and the clamping sleeve 13. The engagement of the slot 17 and the insert 16 restricts the horizontal movement of the clamping sleeve 13 relative to the cup body 12 (specifically, the circumferential movement of the clamping sleeve 13 relative to the cup body 12). Figure 2-4 As shown, the insert 16 is disposed on the outer side of the clamping sleeve 13, and the slot 17 is disposed on the inner side of the cup body 12. The number of slots 17 and inserts 16 are several sets, evenly distributed circumferentially and corresponding one-to-one. The vertical positioning structure includes a locking groove 19 disposed on one of the cup body 12 and the clamping sleeve 13, and a locking block 18 disposed on the other of the cup body 12 and the clamping sleeve 13, which cooperates with the locking groove 19. The locking groove 19 and the locking block 18 are located between the opposite sides of the cup body 12 and the linkage plate 14. The cooperation of the locking groove 19 and the locking block 18 is used to restrict the vertical movement of the clamping sleeve 13 relative to the cup body 12. Figure 2-4 As shown, the fastening groove 19 is provided on the side of the cup body 12, the fastening block 18 is provided on the linkage plate 14, the linkage plate 14 is located on the insertion block 16, and the fastening groove 19 is located on the slot 17. The number of fastening grooves 19 and fastening blocks 18 are several sets, evenly distributed along the circumference and corresponding one to one. The number of fastening grooves 19, fastening blocks 18, slots 17 and insertion blocks 16 are all the same.

[0103] The first joint portion 24 is provided with a first thinning structure for reducing the thickness of the first joint portion 24 and forming a first thinning position 240 on the first joint portion 24. The first thinning structure and the first thinning position 240 make it easier for the elastic clamping element 2 to swing down or tilt up, so that the elastic clamping element 2 can adapt to changes in the size of the bottle 4. The thickness of the first thinning position 240 is less than the thickness of the arm portion 21. The first thinning structure includes a first thinning groove 241 provided on the first joint portion 24. The first thinning groove 241 is located at the lower part of the first joint portion 24, so as to avoid the first thinning groove 241 being exposed on the upper surface of the first joint portion 24 that is easily visible to the user. The two ends of the first thinning groove 241 respectively penetrate through the two ends of the first joint portion 24. The first joint portion 24 is arc-shaped, and the concave surface of the arc-shaped first joint portion 24 faces downward. This shape of the first joint portion 24 facilitates the elastic clamping element 2 to swing down or tilt up.
