Abstract
Description
Technical Field
[0001] This utility model relates to the field of stirring device technology, and in particular to a novel stirring device. Background Technology
[0002] Currently, milk frothers on the market generally have the following three structures:
[0003] The first type is a shaft-driven stirring system, where the motor shaft goes directly into the pot body and drives the stirring system directly. Although this type of operation is stable, it is difficult to clean because of the presence of the circuit board, and it cannot be put into dishwashers or other cleaning devices.
[0004] The second type is a stirring head with a magnet. A magnetic drive head is mounted on a motor shaft, and a support with a magnet is placed inside the pot (cup). The motor drives the drive head, and the interaction between the two magnets causes the stirring head on the support to rotate at high speed to froth the milk. Although the stirring head can be removed from the pot for easy cleaning, this type of operation is unstable. It is easy for the stirring head to demagnetize and stop rotating if it is not placed in the correct position or is not centered. It has high requirements for manufacturing tolerances and, because of the presence of the circuit board, it cannot be put into dishwashers or other cleaning devices.
[0005] The third type has appeared on the market, which separates the cup body from the electrified base based on the second type. This allows the cup to pass through dishwashers commonly used in Europe and America, greatly solving the cleaning problem. However, it still has the same demagnetization problem as the second type, making it easy for the device to malfunction. At the same time, the stirring is achieved by the interaction of magnetic forces between magnets, and the stirring head inside the upper cup body is driven by a motor with a magnetic stirring head. This requires high dimensional and process precision.
[0006] Therefore, all products currently on the market face this technical challenge, resulting in a relatively high rate of defective products. There is an urgent need for a technology to improve this quality issue, ensuring stable performance, excellent quality, and ease of use. Utility Model Content
[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of stirring device.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A novel stirring device includes a base and a cup body. The base houses a main board and a motor electrically connected to the main board. A drive head is mounted on the rotating shaft of the motor. A mounting slot is provided at the top of the base, and the drive head is located at the mounting slot. The bottom of the cup body can be inserted into the mounting slot. An inwardly recessed mounting groove is provided on the bottom end face of the cup body. A shaft is mounted on the bottom of the mounting groove via a bearing. One end of the shaft is placed inside the cup body and connected to the stirring head. The other end of the shaft is placed at the groove of the mounting slot and is provided with a transmission head. The drive head and the transmission head are attracted to each other by a magnetic attraction component.
[0010] Preferably, the magnetic attractor is a magnet or a combination of a magnet and an iron block.
[0011] Preferably, a waterproof gasket is provided at the mounting groove of the shaft.
[0012] Preferably, the stirring head is provided with a matching hole, and the matching hole is provided with two symmetrical and outwardly protruding bosses. The shape of the end of the shaft placed in the cup body corresponds to the shape enclosed by the two bosses, and the side of the shaft is provided with a beveled groove.
[0013] Preferably, the inner end face of the base is provided with a clearance groove relative to the location where the drive head is provided, and the drive head is placed in the clearance groove;
[0014] Alternatively, the mounting slot may be provided with a clearance hole at the drive head, so that the drive head is exposed.
[0015] Preferably, a knob is provided on the base, and the knob is electrically connected to the main board.
[0016] By adopting the above-mentioned solution, this utility model separates the cup body for holding food and the base with the circuit system, so that the cup body only has mechanical components, and the cup body can be put into the dishwasher for cleaning; at the same time, the positioning design of bearings and shafts, on the one hand, relies on the bearings as the connecting parts between the cup body and the bearings to make the rotation more stable, and on the other hand, relies on the structural positioning to ensure that after each assembly, the cup body is in a reasonable position, and the drive head and transmission head are aligned, thereby ensuring the stability of magnetic transmission.

[0024] like Figures 1 to 4As shown, this embodiment provides a novel stirring device, including a base 1 and a cup body 2. The base 1 has a built-in main board 11 and a motor 12 electrically connected to the main board 11. A drive head 13 is provided on the rotating shaft of the motor 12. The top of the base 1 is provided with a mounting slot 14. The drive head 13 is located at the mounting slot 14. The bottom of the cup body 2 can be inserted into the mounting slot 14. The bottom end face of the cup body 2 is provided with an inwardly recessed mounting groove 21. A shaft 23 is mounted on the bottom of the mounting groove 21 through a bearing 22. One end of the shaft 23 is placed inside the cup body 2 and connected to a stirring head 24. The other end of the shaft 23 is placed at the groove of the mounting groove 21 and is provided with a transmission head 25. The drive head 13 and the transmission head 25 form a mutual attraction force by a magnetic suction member 3.
[0025] This embodiment mainly involves a separate design for the cup body (for holding food or beverages, such as milk, chocolate powder, or oatmeal) and the base 1 containing the circuit system. This allows the cup body 2 to have only mechanical components, making it dishwasher safe for washing without the need for hand washing, thus making cleaning more convenient. Simultaneously, the positioning design of the bearing 22 and shaft 23 ensures stable rotation by using the bearing 22 as a connector to the cup body 2, and the structural positioning ensures that the cup body 2 is in a suitable position after each assembly, keeping the drive head 13 and transmission head 25 aligned, thereby ensuring stable magnetic transmission.
[0026] In practical use, the cup 2 containing the beverage to be stirred or frothed is placed on the mounting slot 14 of the base 1. Alternatively, the cup 2 can be placed on the base 1 first, and then the beverage can be poured into the cup 2. Once the cup 2 and the base 1 are in place, the motor 12 is turned on. After the motor 12 is powered on, the drive head 13 on the motor 12's rotating shaft will rotate. Because the drive head 13 and the transmission head 25 are attracted to each other by the magnetic attraction 3, the transmission head 25 can be rotated in the air. The stirring head 24 located at the other end of the shaft 23 will then stir or froth the beverage. The shaft 23 is kept stable during rotation thanks to the bearing 22.
[0027] Furthermore, the magnetic transmission between the drive head 13 and the transmission head 25 mainly relies on the mutual attraction between the magnetic suction components 3. In this embodiment, the magnetic suction component 3 can be a magnet or a combination of a magnet and an iron block. That is, the drive head 13 can be directly set as a magnet, and the transmission head 25 can be embedded with a magnet, or one of the magnets can be replaced with an iron block. Of course, the optimal solution is to use magnets for both.
[0028] Furthermore, in order to provide waterproofing for the shaft 23, a waterproof gasket 26 is inserted through the mounting groove 21 of the shaft 23. The waterproof gasket 26 is inserted through the shaft 23 and fills the gap at the shaft 23 to achieve waterproofing.
[0029] Furthermore, depending on whether it is for stirring or foaming, different stirring heads 24 need to be replaced. For example, a horizontal bar is used for stirring, while a spiral mesh ring is used for foaming. Therefore, this embodiment has the function of replacing the stirring head 24. The stirring head 24 is provided with a mating hole 101. The mating hole 101 is provided with two symmetrical and outwardly protruding bosses 102. The shape of the end of the shaft 23 placed in the cup body 2 corresponds to the shape enclosed by the two bosses 102. The side of the shaft 23 is provided with a slanted groove 103. The shape of the bosses 102 can be a semi-circular ellipse. In this way, during assembly, the bosses 102 and the holes enclosed by the bosses 102 are first put into the shaft 23, and then slightly rotated so that the bosses 102 are respectively embedded in the slanted grooves 103. In this way, the stirring head 24 cannot be pulled out. The direction of rotation driven by the motor 12 corresponds to this direction, so it will not rotate back and forth and the stirring head will not detach. Once the rotation stops, it can be rotated back to disengage the boss 102 from the inclined groove 103, allowing the stirring head 24 to be pulled out and replaced with another stirring head 24. This stirring head 24 is replaceable and easy to clean.
[0030] Furthermore, to bring the drive head 13 and the transmission head 25 closer together, the inner end face of the base 1 in this embodiment is provided with a clearance groove 15 relative to the location where the drive head is located. The drive head 13 is placed in the clearance groove 15. This makes the housing thinner at this location by relying on the clearance groove 15, allowing the drive head 13 to move further upward to reduce the distance between it and the transmission head 25. Alternatively, a clearance hole (not shown in the figure, but the specific design could be to directly open through the clearance groove 15 to form a clearance hole) can be provided directly at the location of the drive head 13, exposing the drive head 13. After the drive head 13 is exposed, the magnetic attraction force between it and the transmission head 25 can be strengthened.
[0031] In addition, a knob 16 is provided on the base 1 in this embodiment. The knob 16 is electrically connected to the motherboard 11. The user controls the motor to start by rotating the knob 16. As for the power supply, a charging port can be provided and a rechargeable battery can be provided inside, or a DC power supply port can be directly provided.
[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
