Description

Technical Field

[0001] This application relates to the field of electric stirring technology, and more particularly to an electric coffee milk frother. Background Technology

[0002] In recent years, with the promotion of coffee, more and more people choose to drink coffee to refresh themselves when they are tired. To further enhance the taste of coffee, milk is often added to neutralize its bitterness. A milk frother is a stirring tool used to emulsify milk. It mainly uses a rotating agitator to change the molecular structure of milk, thus transforming it into milk foam, thereby improving the taste and appearance of the coffee. Currently, milk frothers usually involve directly placing the agitator into the milk for stirring. However, due to the small size of the agitator, the emulsification effect is often not very pronounced.

[0003] Current milk frothers require the user to hold them and keep them suspended in the air to prevent the mixing head from contacting the bottom of the cup; however, prolonged suspension can cause arm pain, affecting the user experience. Furthermore, to protect the mixing head, a protective device is usually attached after mixing, which undoubtedly increases the complexity of operating the milk frother. Therefore, there is an urgent need for a coffee milk frother that offers good emulsification and is simple and comfortable to use. Utility Model Content

[0004] One objective of this application is to provide an electric coffee milk frother that can solve at least one of the defects in the aforementioned background technology.

[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: an electric coffee milk frother, comprising a handle and a stirring rod, wherein a drive assembly is installed inside the handle, and a through hole coaxial with the drive assembly is provided on the handle, and the stirring rod passes through the through hole and is fixedly connected to the drive assembly; an installation head is connected to the end of the stirring rod, and an installation hole for installing the stirring head is provided on the installation head; a hollow cover is installed on the handle, and the stirring rod is sleeved inside the cover, and a perforation for exchanging liquid is provided on the side of the cover.

[0006] With the above setup, the driving component drives the stirring rod to rotate the stirring head at high speed, thereby emulsifying the milk. When storing the milk frother, the cover protects the stirring rod from bending under external force. When the milk frother is working, the milk or the liquid being stirred forms a high-speed, irregular flow inside and outside the cover, breaking down the molecular structure for better emulsification. The mounting head is a universal part; different types of stirring heads engage with the mounting head through mounting holes, allowing users to replace different types of stirring heads according to their needs.

[0007] Preferably, the mounting holes are located on the end face of the mounting head, and there are multiple mounting holes arranged at equal intervals around the axis of the mounting head. The stirring head is elastically engaged within the mounting holes. This arrangement further improves the installation stability of the stirring head. The equal intervals between the mounting holes balance the angular momentum of the stirring head during rotation, preventing it from detaching under high-speed rotation. In addition, the elastic engagement method also improves the speed of stirring head replacement.

[0008] Preferably, a connector is provided between the mounting head and the stirring rod, and a cooperating connecting mechanism is provided between the connector and the stirring rod. The connector has a mounting block, and the mounting head has a mounting groove for engaging the mounting block. This configuration allows the mounting head and the stirring rod to be connected via the connector. Inserting the mounting block into the mounting groove secures the mounting head to the connector. The mounting block also presses and limits the movement of the stirring head, preventing it from shaking.

[0009] Preferably, the connecting mechanism includes a connecting block and a connecting groove. The connecting block is disposed on the connecting member, and the connecting groove is disposed on the stirring rod. The connecting block and the connecting groove are provided with mating threads. With this configuration, when the user needs to replace different stirring heads, they can simply unscrew the connecting member and replace it with a connecting member that has the different stirring head.

[0010] Preferably, the cover is detachably installed at the bottom of the handle. The handle has a connecting part with a slot, and the inner wall of the cover has a locking block for engaging the slot. This design allows the cover to be fixedly installed on the handle through the engaging action of the slot and the locking block. When cleaning the milk maker, the cover can be quickly removed by simply twisting it in the opposite direction.

[0011] Preferably, the cover is trumpet-shaped, and the narrow end of the cover is connected to the connecting part. This design allows the milk frother to be supported by the cover, and when the user removes their hand from the handle while the milk frother is in operation, the milk frother can remain stably upright in the container.

[0012] Preferably, the drive assembly includes a motor, a first mounting portion is provided inside the handle, and the motor is limited and mounted on the first mounting portion; the rotation shaft of the motor is fixedly connected to the stirring rod, and a shock-absorbing sleeve is provided around the motor. This configuration allows the position of the motor to be limited by the first mounting portion, and the shock-absorbing sleeve prevents the motor from colliding with the inside of the handle due to vibration, further improving the motor's safety.

[0013] Preferably, a second mounting portion is provided within the handle, and a power supply component is installed within the second mounting portion. The power supply component is connected to the motor circuit. This configuration allows the position of the power supply component to be defined by the second mounting portion. The power supply component can serve as a power source to drive the motor, thereby causing the stirring rod to rotate the stirring head at high speed and emulsify the milk.

[0014] Preferably, a circuit board connected to the power supply assembly is installed inside the handle. The circuit board is equipped with a switch, an indicator light, and a charging port. This configuration allows the switch to control the start and stop of the milk frother, the indicator light to display the current operating status of the milk frother, and the charging port to recharge the power supply assembly when its battery is low.

[0015] Preferably, the handle includes a first housing and a second housing, and the first housing and the second housing are provided with mutually cooperating mounting structures. This configuration allows the first housing and the second housing to be separated via the mounting structures when the milk maker malfunctions, thereby improving the convenience of maintenance.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: This invention uses a drive assembly to drive the stirring rod, which in turn drives the stirring head to rotate at high speed, thus agitating milk or other liquids. The housing protects the stirring rod, preventing it from bending under external force. When the milk frother is working, the milk or other liquid being agitated flows rapidly and irregularly inside and outside the housing, breaking down the molecular structure and achieving emulsification. Users can replace the stirring head with different types to achieve better emulsification results.

[0017] The mounting head has multiple mounting holes, and the stirring head is spring-loaded and snaps into the mounting head. Users can quickly replace the stirring head by pressing it or directly turning the connector. The cover is trumpet-shaped, with its narrow end connecting to the connector. The cover supports the milk frother, ensuring it remains stable in the container even when the user removes their hand from the handle during operation. This invention offers advantages such as convenient operation and excellent emulsification. Attached Figure Description

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] One aspect of this application provides an electric coffee milk frother, one preferred embodiment of which is, for example... Figure 1 and Figure 2 As shown, the device includes a handle 1 and a stirring rod 100. A drive mechanism is installed inside the handle 1, which has a through hole coaxial with the drive assembly. The stirring rod 100 passes through the through hole and connects to the drive mechanism, enabling the drive mechanism to drive the stirring rod 100 to rotate at high speed, thus achieving a stirring function. A mounting head 2 is connected to the end of the stirring rod 100 away from the drive mechanism. The mounting head 2 has a mounting hole 21 for mounting a stirring head (not shown in the figure). Fixing the stirring head onto the mounting head 2 allows it to rotate synchronously with the stirring rod 100, causing the milk or the liquid being stirred to flow at high speed within the container, altering the molecular structure and achieving an emulsification effect. The mounting head 2 can be used as a universal part; different types of stirring heads can be engaged with the mounting head 2 through the mounting hole 21, allowing users to replace different types of stirring heads according to their needs.

[0031] Furthermore, such as Figure 1 As shown, a hollow cover 4 is also installed on the handle 1, and the stirring rod 100 is sleeved inside the cover 4. The side of the cover 4 is provided with a perforation 41 for exchanging liquid. When the milk frother is working, the milk or the liquid being stirred flows at high speed with the stirring head. At this time, the liquid inside the cover 4 collides with the cover 4 under the action of centrifugal force, and some of the liquid inside the cover 4 is discharged to the outside of the cover 4 through the perforation 41. By affecting the flow speed of the liquid outside the cover 4, the liquid is made to flow irregularly, thereby achieving a better emulsification effect.

[0032] In addition, the cover 4 also serves a protective function. When the milk maker is stored, the cover 4 can prevent the stirring rod 100 from bending under external force, further improving the safety of the milk maker.

[0033] It should be noted that the mixing head of a traditional milk frother is usually integrated with the mixing rod 100, which limits its application. When the milk frother needs to be replaced with a different type of mixing head, the mixing rod 100 usually needs to be removed as well, which is a relatively complicated operation.

[0034] To address the aforementioned issues, in this embodiment, as follows: Figure 3As shown, mounting holes 21 are provided at the end of the mounting head 2, and there are multiple mounting holes 21. These mounting holes 21 are arranged at equal intervals around the axis of the mounting head 2. This arrangement of mounting holes 21 at equal intervals balances the angular momentum of the stirring head during rotation, preventing it from detaching under high-speed rotation and further improving the installation stability of the stirring head. To increase the speed of changing the stirring head, the stirring head is elastic. By pressing the stirring head and partially inserting it into the mounting hole 21, the stirring head will engage with the mounting hole 21 under its own elasticity.

[0035] Furthermore, such as Figure 4 and Figure 5 As shown, a connector 3 is installed between the mounting head 2 and the stirring rod 100. A cooperating connection mechanism is provided between the connector 3 and the stirring rod 100 to ensure stable installation of the connector 3 on the stirring rod 100. The connector 3 has a mounting block 32, and the mounting head 2 has a mounting groove 22 for engaging with the mounting block 32. During installation, the mounting head 2 is inserted into the mounting groove 22 to securely connect to the connector 3. The mounting block 32 also presses and limits the stirring head, preventing it from shaking. The mounting block 32 and the mounting groove 22 can be engaged by an interference fit. In other embodiments, other fitting methods can be used to improve the connection stability between the mounting head 2 and the connector 3. In this way, the stirring rod 100, the connector 3, and the mounting head 2 can be connected into an integrated structure, which improves the stability of the milk frother during stirring.

[0036] Specifically, such as Figure 5 As shown, the connecting mechanism includes a connecting block 31 and a connecting groove 101. The connecting block 31 is disposed on the connecting member 3, and the connecting groove 101 is disposed on the stirring rod 100. The mating surfaces of the connecting block 31 and the connecting groove 101 are provided with mutually mating threads. When the user needs to replace different stirring heads, he / she can simply unscrew the connecting member 3 and replace it with a connecting member 3 that has a different stirring head.

[0037] In this embodiment, as Figure 6 As shown, the cover 4 is detachably installed at the bottom of the handle 1. The handle 1 is provided with a connecting part 400, and the connecting part 400 is provided with a slot 401. The inner wall of the cover 4 is provided with a locking block 42 for engaging with the slot 401. The cover 4 can be fixedly installed on the handle 1 by engaging the slot 401 and the locking block 42. When the milk maker needs to be cleaned, the cover 4 can be quickly disassembled by simply twisting the cover 4 or the handle 1 in the opposite direction.

[0038] Specifically, such as Figure 1As shown, the cover 4 is flared, narrower at the top and wider at the bottom. The narrow end of the cover 4 is connected to the connecting part 400 to improve the support performance of the cover 4. When the breast frother is working, the cover 4 can support the breast frother, so that the breast frother can stand stably in the container even if the user takes their hand off the handle 1. This further improves the user's comfort and avoids arm pain caused by holding the breast frother for a long time.

[0039] In this embodiment, as Figure 2 As shown, the drive assembly includes a motor 200. A first mounting portion is provided inside the handle 1, which is used to mount the motor 200 and limit its movement, thereby preventing the motor 200 from shaking inside the handle 1. Furthermore, a shock-absorbing sleeve 201 is fitted onto the surface of the motor 200. The shock-absorbing sleeve 201 prevents the motor 200 from colliding with the inside of the handle 1 due to vibration, further improving the safety of the motor 200. The shock-absorbing sleeve 201 is preferably made of soft and elastic materials such as sponge or silicone.

[0040] Furthermore, the handle 1 contains a second mounting part and a circuit board 5 connected to the second mounting part. A power supply component 300 is mounted within the second mounting part, and the power supply component 300 is electrically connected to the motor 200. The power supply component 300 can power the motor 200, enabling the rotating shaft of the motor 200 to drive the stirring rod 100 to rotate synchronously. The circuit board 5 is equipped with a switch 51, an indicator light 52, and a charging port 53. The user can control the start and stop of the milk frother using the switch 51. When the user presses the switch 51, the motor 200 starts running, and the indicator light 52 illuminates, displaying the current operating status of the milk frother. Of course, the milk frother can also be set to multiple operating levels. The user can adjust the level by pressing the switch 51; different levels correspond to different colors or numbers of indicator lights 52. When the power supply component 300's battery is low, it can be charged through the charging port to avoid frequent replacement of the power supply component 300.

[0041] In this implementation, such as Figure 7 As shown, the handle 1 includes a first housing 11 and a second housing 12, with mutually cooperating mounting structures on the first housing 11 and the second housing 12. Installation is completed by placing the power supply assembly 300 and the drive assembly into the first housing 11, and then closing the second housing 12 onto the first housing 11. When the milk maker malfunctions, the first housing 11 and the second housing 12 can be separated through the mounting structures, thereby improving the convenience of maintenance.

[0042] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
