Description

Technical Field

[0001] The utility model relates to the technical field of maternal and infant products, and particularly relates to a milk shaker. Background Art

[0002] A milk shaker is a device designed to shake a milk bottle to dissolve the milk powder quickly. Most milk shakers have a rotating drum, which the milk bottle is placed in and drives the drum to rotate rapidly. The milk bottle rotates synchronously with the drum to dissolve the milk powder quickly.

[0003] However, during use, the inventor discovered that the prior art milk shaker had the following drawbacks: While the milk shaker has a temperature control function, the temperature measurement component has significant deviations in the liquid temperature, which can cause the actual temperature of the liquid to be too high or too low. The temperature of the liquid consumed by infants is crucial to their health and comfort. If the liquid is too hot, it can burn the infant's oral and esophageal mucosa, causing pain and discomfort. If the liquid is too cold, it can increase the burden on the infant's digestive system, causing indigestion, bloating, or diarrhea. Utility Model Content

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0036] In the description of this utility model, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, contact connections, or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0037] A milk shaker 1, such as Figures 1-10 As shown, it includes: a base 10, a milk-shaking component 20 and a driving component 30. The milk-shaking component 20 has a placement cavity 215, which is used to accommodate a milk bottle; the driving component 30 is arranged below the milk-shaking component 20, and the driving component 30 includes a fixed shaft 31 and a driving part 32. The fixed shaft 31 is fixedly connected to the base 10, and the driving part 32 is connected to the milk-shaking component 20. The driving part 32 is sleeved on the outer periphery of the fixed shaft 31, and the driving part 32 is suitable for rotating relative to the fixed shaft 31 to drive the milk-shaking component 20 to rotate; the driving part 32 is provided with a supporting surface 320 on the side facing the milk-shaking component 20, and the supporting surface 320 is suitable for fitting with the bottom surface of the milk-shaking component 20 to support the milk-shaking component 20 and drive the milk-shaking component 20 to rotate.

[0038] It can be understood that by the support surface 320 of the driving part 32 being in contact with the bottom surface of the milk-shaking assembly 20, the flatness between the driving part 32 and the milk-shaking assembly 20 is improved, and then when the driving assembly 30 supports and drives the milk-shaking assembly 20 to rotate, the milk-shaking assembly 20 can rotate more smoothly, reducing the risk of the bottle in the placement cavity 215 tilting or shaking, reducing the generation of bubbles in the liquid, and being more beneficial to the health of the baby.

[0039] In some embodiments, as Figure 3-Figure 5As shown, the driving part 32 includes a support member 322 and a rotating member 321. The support member 322 has a supporting portion 3221. The supporting surface 320 is defined on a side of the support portion 3221 facing the milk shaking component 20, so as to be suitable for fitting with the bottom surface of the milk shaking component 20; the rotating member 321 is connected to the lower side of the support member 322 in an integral or separate manner, and the rotating member 321 is suitable for rotating relative to the fixed shaft 31 to drive the support member 322 to rotate.

[0040] It can be understood that, by the support surface 320 located on the support member 322 being in contact with the bottom surface of the milk-shaking component 20, the contact area between the support member 322 and the milk-shaking component 20 is increased, and the flatness is improved, so that the supporting force of the support member 322 on the milk-shaking component 20 is more evenly dispersed on the bottom surface of the milk-shaking component 20. In other words, the supporting force of the support member 322 on the milk-shaking component 20 is dispersed over a larger area, which is beneficial to reducing the shaking of the milk-shaking component 20 due to the uneven supporting force.

[0041] In at least one embodiment, the drive assembly 30 further includes a stator sleeved on the outer periphery of the fixed shaft 31, and the rotating member 321 is implemented as a rotor sleeved on the outer periphery of the stator, thereby driving the support member 322 to rotate through the Lorentz force between the stator and the rotor. It is understandable that if the stator is sleeved on the outer side of the rotor and connected to the support member 322 through the inner rotor, the supporting force of the inner rotor on the support member 322 is concentrated in the middle area of ​​the support member 322. In this embodiment, an outer rotor is used to connect to the support member 322, and the contact surface between the outer rotor and the support member 322 is annular, which is conducive to increasing the contact area between the outer rotor and the support member 322, so that the supporting force of the outer rotor on the support member 322 is distributed over a larger area, which is conducive to reducing the deformation of the support member 322, thereby improving the flatness of the support member 322, and making the milk shaking assembly 20 more stable during rotation and reducing the generation of bubbles. In addition, the use of an outer rotor can reduce the volume of the permanent magnet, so that the driving component 30 has better operating stability and further improves the smoothness of the milk shaking component 20 during the rotation process.

[0042] It is worth mentioning that, compared with connecting the motor and the milk-shaking assembly 20 through a transmission assembly such as a pulley, so that the motor indirectly drives the milk-shaking assembly 20 to rotate through the transmission assembly, in this embodiment, the rotating member 321 is directly connected to the support member 322, and drives the milk-shaking assembly 20 to rotate through the support member 322, which is beneficial to improving the reliability of the transmission and making the structure of the milk shaker 1 more compact.

[0043] In some embodiments, as Figure 2-Figure 5As shown, the drive assembly 30 further includes a fixed member 33 having a chamber 331 for accommodating the rotating member 321. Specifically, the fixed member 33 is disposed around the outer periphery of the rotating member 321, thereby protecting the rotating member 321 and extending its service life. Furthermore, the fixed member 33 also provides a soundproofing effect, thereby reducing noise generated during use of the milk shaking assembly 20 and thereby enhancing the user experience.

[0044] Further, such as Figure 3 and Figure 7 As shown, the support member 322 also has a second matching portion 3224, which extends axially from the support portion 3221 into the cavity 331 of the fixing member 33, and the outer peripheral surface of the second matching portion 3224 is radially opposite to the inner peripheral surface of the fixing member 33, and the lower side edge of the support portion 3221 is axially opposite to the upper end surface of the fixing member 33, so that the fixing member 33 is suitable for auxiliary positioning of the support member 322.

[0045] Specifically, the outer circumference of the second fitting portion 3224 is adapted to fit with the inner circumference of the fixing member 33, or there is a reasonable installation gap between the outer circumference of the second fitting portion 3224 and the inner circumference of the fixing member 33, so that the fixing member 33 can radially limit the support member 322. Furthermore, the lower side edge of the support portion 3221 is adapted to fit with the upper end surface of the fixing member 33, or there is a reasonable installation gap between the lower side edge of the support portion 3221 and the upper end surface of the fixing member 33, so that the fixing member 33 can assist in supporting the outer side of the support member 322, which is beneficial to prevent the outer side of the support member 322 from sagging and deformation due to gravity and other reasons, thereby improving the flatness of the support surface 320, so that the support surface 320 remains in contact with the bottom surface of the milk shaking assembly 20, which is beneficial to prevent the milk shaking assembly 20 from shaking during rotation.

[0046] In at least one embodiment, Figure 3 and Figure 5 As shown, a bearing 323 is disposed between the support member 322 and the fixed shaft 31. This reduces friction between the support member 322 and the fixed shaft 31, allowing the support member 322 to rotate more smoothly and stably. Specifically, the support member 322 is rotatably connected to the fixed shaft 31 via the bearing 323, and the rotating member 321 is fixedly connected to the support member 322, thereby driving the support member 322 to rotate about the fixed shaft 31.

[0047] In at least one other embodiment, the rotating member 321 is rotatably connected to the fixed shaft 31 through a bearing 323, and the support member 322 is connected and fixed to the rotating member 321, so that the rotating member 321 can drive the support member 322 to rotate around the fixed shaft 31. This application does not impose any specific restrictions on this.

[0048] In some embodiments, as Figure 3-Figure 5 As shown, the drive assembly 30 further includes a control module 34 for controlling the rotation of the drive portion 32. Figure 10 As shown, the control module 34 includes a ring-shaped circuit board 341, leads 342, and terminals 343. The circuit board 341 is sleeved on the fixed shaft 31 and located below the driving unit 32, making the structure of the driving assembly 30 more compact, reducing the space occupied by the driving assembly 30, and helping to reduce the overall size of the breast shaker 1.

[0049] Furthermore, the lead 342 connects the conductive circuit board 341 and the terminal 343 , and the terminal 343 is used to connect to the main control board of the milk shaker 1 , so that the main control board can control the driving component 30 through the circuit board 341 , thereby improving the controllability of the driving part 32 .

[0050] In some embodiments, as Figure 3 and Figure 5 As shown, the support member 322 further has a first mating portion 3223 that protrudes axially from the middle region of the support portion 3221 toward the milk-shaking assembly 20. Furthermore, the milk-shaking assembly 20 includes a cradle 21 defining a placement cavity 215 for placing a feeding bottle therein. The bottom wall 211 of the cradle 21 is adapted to mate with the support surface 320, thereby supporting the cradle 21 and driving its rotation.

[0051] Furthermore, if Figure 3 and Figure 5 As shown, the cradle 21 has a connecting groove 214 recessed upward from the bottom wall 211 of the cradle 21. The connecting groove 214 is mounted and adapted to fit within the first mating portion 3223 to position and connect the cradle 21 and the support member 322. In other words, the plug-in engagement between the connecting groove 214 and the first mating portion 3223 allows the support member 322 to radially limit the cradle 21, improving the coaxiality between the cradle 21 and the support member 322. This helps prevent eccentric rotation between the cradle 21 and the feeding bottle, thereby improving the smoothness of the feeding bottle's rotation and reducing any shaking during the rotation of the feeding bottle.

[0052] In some embodiments, as Figure 3 and Figure 5 As shown, the support portion 3221 is provided with an axially extending first connection hole 3222, which is circumferentially distributed on the outer periphery of the first matching portion 3223; the cradle 21 has a second connection hole 213, which is provided on the bottom wall 211 of the cradle 21 and is axially arranged opposite to the first connection hole 3222 for fixedly connecting the cradle 21 and the support member 322.

[0053] In other words, by providing the first connecting hole 3222 and the second connecting hole 213, a connector is used to connect the support portion 3221 of the support member 322 and the cradle 21, thereby improving the connection strength and reliability between the support member 322 and the cradle 21, and allowing the support member 322 to drive the cradle 21 to rotate synchronously. It is worth mentioning that the connector connecting the support member 322 and the cradle 21 ensures that the support surface 320 of the support member 322 is in contact with the bottom surface of the cradle 21, which helps prevent axial movement of the cradle 21 relative to the support member 322 during rotation, thereby reducing the shaking of the feeding bottle during rotation.

[0054] In other embodiments, the first connection hole 3222 may also be provided in the first matching portion 3223 , and this application does not impose any specific limitation on this.

[0055] In some embodiments, as Figure 9 As shown, the bottom wall 211 of the cradle 21 further defines a groove 212 that communicates with the placement cavity 215. The groove 212 is recessed downward from the bottom wall 211 of the cradle 21. A second connecting hole 213 is defined at the bottom of the groove 212. The groove 212 is used to accommodate the head of the connector. It will be appreciated that the groove 212 communicates with the placement cavity 215, allowing the connector to be screwed into the second connecting hole 213 and the first connecting hole 3222 through the placement cavity 215 and the groove 212, facilitating the installation of the drive assembly 30 and the cradle 21 assembly from bottom to top.

[0056] In other words, the drive assembly 30 can be first installed on the base 10, and then the cradle 21 can be fixedly mounted on the support member 322 of the drive assembly 30, which helps improve the efficiency of installation and removal. Furthermore, the groove 212 can accommodate the head of the connector. When a feeding bottle is placed in the cradle 21, the head of the connector and the feeding bottle are prevented from contacting each other, allowing the feeding bottle to be placed stably in the cradle 21, which helps reduce the shaking of the feeding bottle during rotation. In at least one embodiment, the groove 212 and the second connecting hole 213 can be implemented as countersunk holes.

[0057] Further, such as Figure 2 As shown, the milk shaking assembly 20 further includes a bottom plate 22, which covers the bottom wall 211 of the cradle 21 to cover the groove 212. In other words, the bottom surface of the milk bottle is able to abut against the bottom plate 22, which helps to further improve the flatness, reduce the risk of the milk bottle shaking during rotation, and reduce the generation of bubbles.

[0058] In some embodiments, as Figure 2As shown, the milk shaking assembly 20 also includes an elastic cover 23, which surrounds the cradle 21 and is arranged at the upper end of the cradle 21, and extends into the placement cavity 215 to clamp the milk bottle so that the milk bottle remains in the placement cavity 215, which is beneficial to prevent the milk bottle from moving up and down relative to the cradle 21 during the rotation process, and further reduce the generation of bubbles.

[0059] In some embodiments, as Figure 3 and Figure 6 As shown, the fixed shaft 31 has a main body 312 and at least one mounting portion 313. The upper end of the main body 312 is rotatably connected to the driving portion 32 to support the driving portion 32. The mounting portion 313 extends radially from the lower end of the main body 312. The base 10 is provided with a accommodating cavity 11 and a mounting groove 121. The accommodating cavity 11 is used to accommodate the driving assembly 30. The mounting groove 121 is recessed downward from the base 12 of the base 10. The mounting groove 121 is installed and adapted to the mounting portion 313 to position and connect the fixed shaft 31 and the base 10.

[0060] In other words, the plug-in fit between the mounting groove 121 and the mounting portion 313 allows the base 10 to radially limit the fixed shaft 31, thereby improving the installation efficiency of the breast shaker 1. Furthermore, the mounting portion 313 increases the contact area between the fixed shaft 31 and the base 10, thereby ensuring that the fixed shaft 31 more reliably supports the driving portion 32 and further improving the flatness of the supporting surface 320 of the driving portion 32.

[0061] In at least one embodiment, Figure 6 and Figure 8 As shown, the three mounting portions 313 extend radially from the lower end of the main body portion 312 at intervals, and the three mounting portions 313 are evenly distributed circumferentially, and the inner wall of the mounting groove 121 is suitable for fitting with the outer wall of the mounting portion 313, so that the base 10 can play a circumferential limiting role on the fixed shaft 31, which is beneficial to avoid the fixed shaft 31 from rotating or tilting relative to the base 10, further improving the flatness of the support surface 320 of the driving portion 32, and reducing the risk of shaking or tilting of the milk shaking component 20 during rotation.

[0062] In some embodiments, as Figure 6 and Figure 8As shown, the mounting portion 313 is provided with a first mounting hole 3131, which extends axially through the mounting portion 313. The base 10 has a second mounting hole 122, which is formed at the bottom of the mounting slot 121 and is axially opposed to the first mounting hole 3131, for connecting the fixed base 10 and the fixed shaft 31. In other words, by providing the first mounting hole 3131 and the second mounting hole 122, a connector is provided to connect the fixed shaft 31 and the base 10, thereby improving the connection strength and reliability between the fixed shaft 31 and the base 10 and facilitating the installation, removal, and replacement of the drive assembly 30.

[0063] In some embodiments, as Figure 6 and Figure 10 As shown, the mounting portion 313 is further provided with a boss 3132 that protrudes axially upward from the mounting portion 313. A positioning hole 3411 is formed on the circuit board 341 of the control module 34. The positioning hole 3411 is adapted to fit within the boss 3132, thereby securing the circuit board 341 to the fixed shaft 31. In other words, the boss 3132 serves to limit the circuit board 341 in both the axial and radial directions, improving the connection reliability between the circuit board 341 and the fixed shaft 31 and preventing the circuit board 341 from moving relative to the fixed shaft 31 and generating abnormal noise.

[0064] In at least one embodiment, the radial dimension of the boss 3132 is slightly larger than the radial dimension of the positioning hole 3411, so that the boss 3132 can be engaged with the circuit board 341 through the positioning hole 3411, which is beneficial to avoid axial movement of the circuit board 341 relative to the fixed shaft 31, and further improve the connection reliability between the circuit board 341 and the fixed shaft 31.

[0065] In some embodiments, as Figure 2 and Figure 11 Figure 14 As shown, the milk shaker 1 also includes a temperature measuring assembly 40. The upper end of the temperature measuring assembly 40 extends into the placement cavity 215 of the milk shaking assembly 20. The temperature measuring assembly 40 is movably connected to the base 10 along the axial direction, so that the upper end of the temperature measuring assembly 40 is suitable for contacting the milk bottle. The upper end of the temperature measuring assembly 40 has a sensor 41 for sensing the temperature of the milk bottle. Furthermore, the fixed shaft 31 of the drive assembly 30 has an axially extending cavity 311, which is used to accommodate the temperature measuring assembly 40, so that the fixed shaft 31 and the temperature measuring assembly 40 are slidably connected.

[0066] In some embodiments, as Figure 11-13As shown, the temperature measurement assembly 40 includes a movable rod 43 and a sensor 41. The sensor 41 is fixed to the upper end of the movable rod 43, which extends into the placement cavity 215. The movable rod 43 is axially movable and connected to the base 10, so that the sensor 41 is suitable for contacting the feeding bottle. The movable rod 43 has an axially extending connecting cavity 431, which accommodates the connecting wire of the sensor 41. The temperature sensing portion 411 of the sensor 41 is suspended above the connecting cavity 431. It is worth noting that the contact between the sensor 41 and the feeding bottle includes direct contact and indirect contact.

[0067] It is understood that the provision of the connecting cavity 431 allows the connecting wires of the sensor 41 to be accommodated within the movable rod 43, thereby simplifying the routing of the temperature measurement assembly 40. The movable rod 43 also protects the connecting wires of the sensor 41, thereby improving the reliability of the electrical connection of the sensor 41. Furthermore, the temperature-sensing portion 411 of the sensor 41 is suspended above the connecting cavity 431, which facilitates heat dissipation from the sensor 41, making the temperature measured by the sensor 41 closer to the actual temperature of the liquid in the bottle.

[0068] In some embodiments, as Figure 11 and Figure 13 As shown, the temperature measuring assembly 40 also includes an elastic member 45, which is adapted to extend and retract along the axial direction of the movable rod 43 and drive the movable rod 43 to move upward, so that the sensor 41 contacts the bottle. That is, when the bottle is placed in the cradle 21, the weight of the bottle causes the movable rod 43 to move downward, and the bottom surface of the bottle is thereby aligned with the cradle 21, which helps to improve the flatness and reduce the risk of shaking when the bottle is rotated, thereby reducing the generation of bubbles. Furthermore, the elastic member 45 provides an upward force to the movable rod 43, so that the sensor 41 contacts the bottle, thereby making the temperature measured by the sensor 41 closer to the temperature of the liquid in the bottle, thereby improving the reliability of the temperature control function of the milk shaker 1.

[0069] In at least one embodiment, Figure 11 and Figure 13 As shown, the movable rod 43 includes a main section 433 and an extension section 434 in sequence. The radial dimension of the main section 433 is larger than the radial dimension of the extension section 434, defining a step surface 435 at the junction of the main section 433 and the extension section 434; the elastic member 45 is sleeved on the outer periphery of the extension section 434, one end of the elastic member 45 abuts against the step surface 435, and the other end of the elastic member 45 abuts against the base 10, thereby driving the movable rod 43 to move upward.

[0070] It is understood that by providing the stepped surface 435 on the movable rod 43 and sleeve-mounting the elastic member 45 on the outer periphery of the extension section 434 so that the elastic member 45 is clamped between the stepped surface 435 and the base 10, the structure of the temperature measuring assembly 40 is simplified and compact, which not only helps to reduce the difficulty and cost of manufacturing the movable rod 43, but also reduces the space occupied by the temperature measuring assembly 40, which helps to reduce the size of the milk shaker 1. It is worth mentioning that the elastic member 45 can be implemented as a spring.

[0071] In at least one embodiment, Figure 2 As shown, the main section 433, the extension section 434 and the elastic member 45 are all accommodated in the cavity 311 of the fixed shaft 31 of the driving assembly 30, and the outer peripheral wall 422 of the main section 433 is suitable for fitting with the inner peripheral wall 422 of the fixed shaft 31, so that the fixed shaft 31 can limit the movable rod 43, which is conducive to keeping the movable rod 43 in vertical movement.

[0072] In some embodiments, as Figure 11 As shown, a bottom hole 123 is formed on the base 12 of the base 10, and the extension section 434 of the movable rod 43 is adapted to pass through the bottom hole 123 to extend to the bottom of the base 10; the temperature measuring assembly 40 further includes a positioning member 44, which is fixed to the end of the extension section 434. The radial dimension of the positioning member 44 is larger than the radial dimension of the bottom hole 123, so that the positioning member 44 can be maintained below the base 10, thereby limiting the maximum length of the movable rod 43 extending into the placement cavity 215, thereby preventing the temperature measuring assembly from being separated from the base 10. In at least one embodiment, the positioning member 44 and the extension section 434 of the movable rod 43 are detachably connected by a snap-fit ​​structure to facilitate installation, removal and replacement of the temperature measuring assembly 40.

[0073] In some embodiments, as Figure 12 and Figure 13 As shown, the temperature measurement assembly 40 further includes an upper cover 42, which is disposed on the outside of the sensor 41 to protect the sensor 41. Furthermore, the upper cover 42 is adapted to abut against a feeding bottle, and the sensor 41 abuts against an end wall 421 of the upper cover 42 to sense the temperature of the feeding bottle. A gap 423 is provided between the sensor 41 and the peripheral wall 422 of the upper cover 42 to allow heat dissipation.

[0074] It will be appreciated that the end wall 421 of the upper cover 42 is adapted to fit snugly against the feeding bottle, and the sensor 41 is adapted to fit snugly against the end wall 421 of the upper cover 42. This helps prevent an air gap between the feeding bottle and the sensor 41, allowing heat from the liquid in the feeding bottle to be transferred to the sensor 41 through the end wall 421 of the upper cover 42, thereby enabling the sensor 41 to more quickly measure the temperature of the liquid in the feeding bottle. Furthermore, a gap 423 is provided between the sensor 41 and the peripheral wall 422 of the upper cover 42, allowing heat from the sensor 41, particularly heat from the pins 412 of the sensor 41, to dissipate promptly, thereby preventing heat from accumulating in the pins 412 and affecting the accuracy of the results measured by the sensor 41.

[0075] It is worth noting that the upper cover 42 can be made of a material with a higher thermal conductivity coefficient to further increase the speed at which the heat of the liquid is conducted to the sensor 41, which is conducive to making the temperature measured by the sensor 41 closer to the real-time temperature of the liquid in the bottle.

[0076] In some embodiments, as Figure 14 As shown, the movable rod 43 includes a temperature measuring section 432, which is located at one end of the movable rod 43 close to the milk shaking assembly 20. The temperature measuring section 432 is capable of fixing the sensor 41 so that the temperature sensing portion 411 of the sensor 41 is suspended above the connecting cavity 431. The upper cover 42 is fixedly connected to the temperature measuring section 432 to cover the outside of the sensor 41.

[0077] That is, the movable rod 43 comprises, from top to bottom, a connecting end temperature-measuring section 432, a main section 433, and an extension section 434. The connecting cavity 431 axially extends through the temperature-measuring section 432, the main section 433, and the extension section 434. The sensor 41 is fixed to the end of the temperature-measuring section 432, thereby allowing the temperature-sensing portion 411 of the sensor 41 to be suspended above the connecting cavity 431. It will be appreciated that heat from the upper cover 42 and the sensor 41 is dissipated through the connecting cavity 431, which helps prevent heat accumulation and ensures that the temperature measured by the sensor 41 is closer to the actual temperature of the liquid in the bottle.

[0078] In at least one embodiment, Figure 12-14 As shown, the upper cover 42 and the temperature measuring section 432 are detachably connected via a snap-fit ​​structure, facilitating installation, removal, and replacement of the sensor 41. Furthermore, when the upper cover 42 is engaged with the temperature measuring section 432, the outer circumference of the upper cover 42 is coplanar with the outer circumference of the main section 433. This maintains a large contact area between the end wall 421 of the upper cover 42 and the feeding bottle while also preventing interference between the upper cover 42 and other structures of the milk shaker 1 during movement of the temperature measuring assembly 40.

[0079] In some embodiments, as Figure 14As shown, the temperature measuring section 432 has an avoidance groove 4322, which is recessed radially inward from the outer periphery of the temperature measuring section 432. The avoidance groove 4322 is capable of accommodating the pin 412 of the sensor 41, so that there is a gap 423 between the pin 412 of the sensor 41 and the peripheral wall 422 of the upper cover 42, thereby allowing heat to be dissipated. This is beneficial for preventing the pin 412 of the sensor 41 from being overheated and affecting the temperature measurement accuracy of the sensor 41, so that the temperature measured by the sensor 41 is closer to the actual temperature of the liquid in the bottle.

[0080] It is worth mentioning that the avoidance groove 4322 is provided to make the structure between the upper cover 42 , the sensor 41 and the movable rod 43 more compact, which is beneficial to reducing the radial size of the temperature measuring component 40 .

[0081] In some embodiments, as Figure 14 As shown, the temperature measuring section 432 further has a wiring hole 4323 that extends radially to connect the avoidance groove 4322 and the connecting cavity 431. The connecting wire of the sensor 41 is adapted to pass through the wiring hole 4323 and enter the connecting cavity 431. In other words, the pin 412 of the sensor 41 bends and extends downward from the temperature sensing portion 411 to be accommodated in the avoidance groove 4322. The end of the pin 412 is connected to a connecting wire, which passes through the wiring hole 4323 to enter the connecting cavity 431. The connecting wire then extends along the connecting cavity 431 and exits from the lower end of the movable rod 43 to connect to the main control board or the circuit board 341 of the drive assembly 30.

[0082] In some embodiments, as Figure 14 As shown, the temperature measuring section 432 is further provided with a pair of positioning grooves 4321. The two positioning grooves 4321 are arranged radially opposite each other to accommodate the pins 412 of the sensor 41, so that the temperature sensing portion 411 of the sensor 41 is maintained above the communication cavity 431. In other words, the pins 412 of the sensor 41 are embedded in the positioning grooves 4321, which helps prevent the sensor 41 from moving relative to the movable rod 43, thereby improving the connection reliability between the sensor 41 and the movable rod 43, and helping to maintain contact between the sensor 41 and the upper cover 42, thereby improving the accuracy of the temperature measurement by the sensor 41.

[0083] It is worth mentioning that the sensor 41 can be conveniently fixed to the movable rod 43 through the positioning groove 4321 , thereby improving the production efficiency of the temperature measuring assembly 40 .

[0084] In some embodiments, as Figure 1 As shown, the milk shaker 1 further includes a housing 50 , in which the milk shaking assembly 20 , the driving assembly 30 and the temperature measuring assembly 40 are all accommodated.
