Description

Technical Field

[0001] The utility model belongs to the technical field of small household appliances, and particularly relates to an egg beater. Background Technique

[0002] An egg beater is a household small appliance used to fully mix the egg white and egg yolk of eggs into egg liquid or beat the egg white and egg yolk separately until foamy. With the popularization of egg beaters, more and more families begin to use egg beaters. By assembling different stirring parts, the egg beater can achieve different functions. For example, by assembling a stirring cage, whipping operation can be achieved, and by assembling a dough hook, dough kneading operation can be carried out, etc. It is convenient to use and has various functions.

[0003] The conventional egg beater directly supplies power to the motor by using an external power supply through a power cord to ensure that the egg beater can operate for a long time. However, limited by the position of the socket and the length of the power cord, the user can only use the egg beater within a specific range. Therefore, there is a cordless egg beater, that is, the power cord is removed, and a rechargeable battery is used to supply power to the motor, so that the user can use the egg beater in different positions. For example, the handheld cordless egg beater disclosed in Patent No. 202120518260.3. However, this structure needs to be equipped with a specific charging base, and charging is achieved by connecting the first charging part at the bottom of the main body to the second charging part inside the base. As a result, during use, the first connecting part is exposed outside and is easily damaged, ultimately affecting the charging performance. Moreover, the rechargeable battery of this structure is placed inside the main body, and it is rather troublesome to disassemble the rechargeable battery later. The main body needs to be disassembled. Considering that other components such as a motor are installed inside the main body, frequent disassembly is likely to increase the damage rate of other components and ultimately reduce the service life of the product. Therefore, the existing cordless egg beaters have problems such as difficult disassembly of the rechargeable battery and easy damage of the charging components exposed outside. Summary of the Utility Model

And in order to display the working state of the whole egg beater, a status indication display screen 2022 electrically connected to the main circuit board 5 is provided above the upper cover 202.

[0038] Preferably, in order to isolate the motor 4 from the circuit board, avoid heat affecting the components of the circuit board, and reduce the service life of the components, a partition 21 that divides the main body housing 201 into upper and lower layers is provided in the main body housing 201. The main circuit board 5 is provided in the lower layer of the main body housing 201. In this structure, by providing the partition 21 in the main body housing 201, the motor 4 is isolated from the circuit board, avoiding heat affecting the components of the circuit board and reducing the service life of the components.

[0039] Preferably, to facilitate the fixation of the motor, a motor installation bin 22 located in the upper layer of the main machine housing 201 is provided above the partition plate 21. The motor 4 is placed in the motor installation bin 22. A transmission mechanism 23 connected between the motor 4 and the stirring member 3 is further provided in the upper layer of the main machine housing 201. In this embodiment, the quick positioning and installation of the motor 4 are realized by setting the motor installation bin 22, and it is also convenient to fix the motor 4.

[0040] Preferably, for convenient use, the transmission mechanism 23 includes a first gear 231, a second gear 211, and a third gear 233. The first gear 231 is connected to the output shaft of the motor 4. The second gear 211 and the third gear 233 are respectively located on both sides of the first gear 231, and the second gear 211 and the third gear 233 mesh with the first gear 231. An insertion sleeve 234 is axially provided on the second gear 211 and the third gear 233. The other ends of the insertion sleeve 234 are respectively inserted with one of the stirring members 3. In this structure, by starting the motor 4 to work, the first gear 231 is driven to rotate, synchronously driving the second gear 211 and the third gear 233 on both sides to rotate, and finally driving the two stirring members 3 to rotate to realize the function of beating eggs.

[0041] Preferably, a start switch 25 and a gear adjustment switch 26 electrically connected to the main circuit board 5 are provided on the holding part 1. In this structure, the gear adjustment switch 26 can adjust the gear of the stirring member 3. The start switch 25 is used as the gear start button of this egg beater. It should be noted that the specific structure of the gear adjustment switch 26 and how to adjust the gear of the stirring member 3 belong to the conventional technology in this field, so no specific description is made here.

[0042] Preferably, to limit the insertion depth of the stirring member 3 into the insertion sleeve 234, a limit ring 27 is provided on the outer body of the rod of the stirring member 3. In this structure, the insertion depth of the stirring member 3 into the insertion sleeve 234 can be limited by setting the limit ring 27.

[0043] Preferably, in order to further protect the motor, a left isolation cover 28 and a right isolation cover 29 that cooperate with each other are connected to the outer shell of the motor 4, and a limiting sleeve 30 is provided on the side above the left isolation cover 28 to facilitate the insertion of the plug sleeve 234, and two limiting columns 11 are provided at the bottom of the right isolation cover 29, and a limiting hole 12 that cooperates with the limiting column 11 is provided in the motor mounting compartment 22. In this embodiment, screw mounting through holes 32 are respectively provided on both sides of the left isolation cover 28 and the right isolation cover 29, and the screws are later passed through the symmetrical screw mounting through holes 32 and threadedly connected with the nuts. Finally, the left isolation cover 28 and the right isolation cover 29 are locked on the outside of the motor 4, and in order to improve the heat dissipation effect, heat dissipation holes can be set on the sides of the left isolation cover 28 and the right isolation cover 29. This structure improves the protection of the motor 4 by setting a protective cover composed of the left isolation cover 28 and the right isolation cover 29 outside the motor 4. At the same time, a limiting sleeve 30 for limiting the socket 234 is set on the side of the left isolation cover 28, so that the socket 234 can only rotate circumferentially with the rotation of the corresponding second gear 211 and the third gear 233, and cannot achieve radial runout, thereby finally improving the stability of the stirring member 3 when rotating.

[0044] In this structure, a magnetic connection is adopted between the external battery pack 6 and the working part 2. When it is needed, the magnet 2 31 at the bottom of the working part 2 is magnetically connected with the magnet 1 7 on the upper surface of the battery pack 6 to fix the battery pack 6. After the battery pack 6 is fixed, it is just ensured that the two-way communication pin 16 is electrically plugged into the two-way communication hole 103, the negative charging pin 15 is electrically plugged into the negative charging hole 102, and the positive charging pin 14 is electrically plugged into the positive charging hole 101, so that the rechargeable battery 8 inside the battery pack 6 supplies power to the charging control circuit board 9 and the motor 4, so that the egg beater disclosed in this application can be powered by an external power supply, and the electrical connection between the battery pack 6 and the working part 2 is a hidden connection, so as to avoid the problem that the charging components are exposed to the outside and easily damaged when not in use, and the overall appearance is also more beautiful;

[0045] Meanwhile, an external connection is adopted between the battery pack 6 and the working part 2, making it relatively convenient to disassemble the battery later. When the internal rechargeable battery 8 is damaged, only the battery pack 6 needs to be disassembled to quickly replace the rechargeable battery 8. Moreover, when replacing the rechargeable battery 8, there is no need to disassemble and assemble the working part 2, avoiding the problem that the existing wireless egg beater has a high damage rate of other components and a reduced service life of the product because the rechargeable battery 8 is placed inside the working part 2 and frequent disassembly is likely to touch other electronic components. In this structure, since the charging control circuit board 9 and the main circuit board 5 are connected by two-way communication, it can ultimately be achieved that when the whole machine is working, the working part 2 can detect the state of the battery pack 6 in real time. When the power of the rechargeable battery 8 inside the battery pack 6 is too low, the low-power signal of the rechargeable battery 8 can be communicated and sent to the main circuit board 5 so that the working part 2 can obtain the low-power information of the battery pack 6. At the same time, when a problem or fault occurs in the rechargeable battery 8 inside the battery pack 6, the working part 2 stops working, and the status indicator display screen 2022 on the upper cover 202 gives a fault code prompt, making the use safer.

[0046] It should be noted that the specific models of the main circuit board 5 and the charging control circuit board 9, how the main circuit board 5 and the charging control circuit board 9 achieve two-way communication connection, how the charging control circuit board 9 obtains the battery power of the rechargeable battery 8, and how the main circuit board 5 generates a fault code and prompts the fault code through the status indicator display screen 2022 after a problem or fault occurs in the rechargeable battery 8 obtained belong to the conventional technologies in this field, so no detailed description will be given.

[0047] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modification of the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made all fall within the protection scope of the present invention.
