Description

Technical Field

[0001] This utility model relates to the technical field of egg beaters, and more particularly to an egg beater with adjustable speed. Background Technology

[0002] An egg beater is a kitchen food processing appliance that uses high-speed rotation to mix, whip, and emulsify ingredients. It typically uses a drive unit to rotate the mixing element, thus processing the ingredients. Different ingredients usually require different speeds. A common practice is to use a gear-and-fork speed control mechanism, which includes a set of corresponding gears and a fork assembly. Moving the operating handle of the fork assembly engages the fork body with different gears in the gear set to adjust the speed.

[0003] However, gear-type forks only have fixed gears and cannot flexibly switch the stirring speed, resulting in poor speed adjustment flexibility. Moreover, the operating stroke of the fork is relatively long, requiring the fork to be pushed or pulled a considerable distance to switch gears, making speed adjustment inconvenient. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides an egg beater that is easy to adjust speed. The beater has a rotating wheel and a potentiometer that work together. When the wheel rotates, the potentiometer can send a speed adjustment signal so that the drive unit can receive the speed adjustment signal and change the speed of the mixing component. The speed adjustment is highly flexible and convenient.

[0005] The technical solution adopted by this utility model to solve its problem is: An adjustable speed egg beater, comprising: The housing includes an installation cavity, a stirring component, and a driving component. The driving component is disposed in the installation cavity, and the stirring component is rotatably mounted on the housing. One end of the stirring component extends into the installation cavity and is connected to the driving component. A speed control assembly includes a rotating wheel and a potentiometer. The potentiometer is installed in the mounting cavity and electrically connected to the driving component. The potentiometer is equipped with a coupling, and the rotating wheel is equipped with a connecting shaft. Both the connecting shaft and the coupling are located in the mounting cavity. The rotating wheel passes through the housing, and the connecting shaft is connected to the coupling. When the rotating wheel rotates, the connecting shaft rotates in conjunction with the rotating wheel, driving the coupling to rotate. The potentiometer is used to send a speed control signal when the coupling rotates, and the driving component is used to receive the speed control signal.

[0006] As an optional implementation, the housing is provided with a connection port and a connection protrusion. The rotating wheel includes a limiting ring and a touch ring. The limiting ring and the touch ring surround to form the rotating groove. The touch ring is rotatably protruding from the connection port. The connection protrusion is disposed in the rotating groove so that when the touch ring rotates, the connection protrusion can be limited and abutted against the limiting ring to restrict the rotation trajectory of the touch ring.

[0007] As an optional implementation, the limiting ring is provided at both the top and bottom of the rotating wheel, and the connecting protrusion is provided at both the top and bottom of the connecting port, so that the connecting protrusion restricts the rotation trajectory of the touch ring from the top and bottom of the connecting port.

[0008] As an optional implementation, the housing is provided with a first limiting part, and the rotating wheel is provided with a second limiting part. The second limiting part is disposed in the rotation direction of the touch ring so that the second limiting part rotates in conjunction with the touch ring when it rotates, and the second limiting part can be limited and abutted against the first limiting part so that the first limiting part restricts the rotation trajectory of the touch ring.

[0009] As an optional implementation, the bottom of the rotating wheel is provided with a receiving cavity, and the connecting shaft and the potentiometer are both disposed in the receiving cavity, which is used to restrict the radial movement of the potentiometer.

[0010] As an optional implementation, the housing is provided with a third limiting part, and the top of the rotating wheel is provided with a fourth limiting part. The fourth limiting part abuts against the third limiting part to restrict the radial movement of the rotating wheel.

[0011] As an optional implementation, the drive unit includes a circuit board and a motor. The circuit board is electrically connected to the potentiometer, and the motor is connected to the stirring element. The circuit board is connected to the motor and is used to receive the speed regulation signal and control the motor to change the rotation speed of the stirring element.

[0012] As an optional implementation, the housing is provided with a mounting position, and the circuit board is disposed in the mounting position.

[0013] As an optional implementation, the stirring element includes a stirring wire and a connecting rod. The housing is provided with a connecting sleeve. One end of the connecting sleeve is connected to the motor, and the other end is connected to the connecting rod. The stirring wire is connected to the connecting rod. When the motor drives the connecting sleeve to rotate, the connecting rod and the connecting sleeve rotate in linkage, thereby driving the stirring wire to rotate.

[0014] As an optional implementation, the touch ring is provided with a plurality of friction protrusions, which are spaced apart on the outer side of the touch ring. The friction protrusions are used to increase the friction between the outside and the touch ring.

[0015] In summary, the egg beater with easy speed adjustment provided by this utility model has the following technical effects: the connecting shaft of the rotating wheel is connected to the coupling of the potentiometer, and the coupling is connected to the driving component. When the rotating wheel rotates, the connecting shaft drives the coupling to rotate, so that the potentiometer sends a speed adjustment signal to the driving component. The driving component changes the stirring speed of the mixing component according to the speed adjustment signal. The potentiometer allows the stirring speed to be freely changed within the speed range, making speed adjustment convenient and highly flexible. Attached Figure Description

[0024] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0025] See Figures 1 to 7 This utility model discloses a convenient speed-adjustable egg beater, including a housing 1 and a speed-adjusting component 2, wherein the housing 1 is connected to the speed-adjusting component 2.

[0026] Specifically, the housing 1 is provided with an installation cavity 11, a stirring component 12, and a driving component 13. The installation cavity 11 is located inside the housing 1, and the driving component 13 is located inside the installation cavity 11. The stirring component 12 is rotatably connected to the housing 1. One end of the stirring component 12 extends into the installation cavity 11 and connects to the driving component 13, while the other end is located outside the housing 1, so that the driving component 13 drives the stirring component 12 to rotate and stir the food.

[0027] The speed control assembly 2 includes a rotary wheel 21 and a potentiometer 22. The potentiometer 22 is disposed in the mounting cavity 11 and is electrically connected to the drive component 13. The rotary wheel 21 is provided with a connecting shaft 211, and the potentiometer 22 is provided with a coupling 221. The connecting shaft 211 is connected to the coupling 221 so that the potentiometer 22 is connected to the rotary wheel 21. Both the connector and the coupling 221 are disposed in the mounting cavity 11. The rotary wheel 21 is rotatably disposed in the housing 1, which facilitates the user to rotate the rotary wheel 21.

[0028] In use, the drive unit 13 starts, driving the stirring component 12 to rotate. When the user wants to adjust the rotation speed of the stirring component 12, they only need to slightly rotate the rotating wheel 21. The rotating wheel 21 drives the connecting shaft 211 to rotate, and the connecting shaft 211 drives the coupling 221 to rotate. The rotation of the coupling 221 changes the resistance value of the potentiometer 22 itself, and the potentiometer 22 outputs a continuous speed adjustment signal to the drive unit 13. The drive unit 13 receives the speed adjustment signal and adjusts the rotation speed of the stirring component 12 according to the speed adjustment signal. During the process, the user only needs to rotate the rotating wheel 21 to achieve speed adjustment, which is convenient. Moreover, the potentiometer 22 is essentially a continuously adjustable resistive element, which contains a resistive body and a brush. When the rotating wheel 21 is rotated, the brush inside the potentiometer 22 will slide continuously in a circle along the resistive body, so that the resistance value of the potentiometer 22 changes linearly and continuously. After this continuously changing speed adjustment signal is sent to the drive unit 13, the drive unit 13 controls the rotation speed of the stirring component 12 to change continuously without interruption. The speed adjustment is not limited by gears and has high flexibility.

[0029] Compared to existing technologies, current egg beaters typically achieve speed adjustment through a gear set and a shift fork assembly. The gear set includes a sliding sleeve and multiple gears with different numbers of teeth, corresponding to multiple speed settings. Different gears are connected to different drive shafts. The shift fork assembly includes a shift fork body and a handle, with the shift fork body connected to both the sliding sleeve and the handle. The handle passes through the egg beater's housing 1. During use, the handle is moved to the desired speed setting. The handle drives the shift fork body, which in turn pushes the sliding sleeve to engage with different gears, thus switching speed settings. During speed adjustment, each speed change requires pushing or pulling the shift fork a considerable distance towards the desired setting. Furthermore, the number of teeth on the gears limits the number and speed of the speed settings. Since the number of teeth is preset, the mixing element 12 can only rotate at the preset speed setting, resulting in low speed adjustment flexibility and poor convenience.

[0030] Therefore, in this embodiment, a potentiometer 22 and a rotating wheel 21 are used in conjunction to achieve speed regulation. When the rotating wheel 21 is rotated, the coupling 221 is driven to rotate, thereby causing the resistance of the potentiometer 22 to change continuously. During this process, the potentiometer 22 continuously sends a speed regulation signal to the driving component 13. Since the resistance of the potentiometer 22 itself changes linearly and continuously, the driving component 13 also receives a continuously changing speed regulation signal, thus driving the stirring component 12 to continuously change its speed. Therefore, the user only needs to slightly rotate the rotating wheel 21 to achieve speed regulation, without having to push it a long distance. Speed ​​regulation is convenient and not limited by gears; it can be freely adjusted within a preset speed range, offering high speed regulation flexibility.

[0031] Furthermore, the specific structure and working principle of the potentiometer are existing technologies and are not part of the technical content to be protected in this application, so they will not be described in detail here.

[0032] Furthermore, the housing 1 is provided with a connection port 14 and a connection protrusion 15. The connection protrusion 15 is located on one side of the connection port 14. The rotating wheel 21 includes a limiting ring 212 and a touch ring 213, and the limiting ring 212 and the touch ring 213 surround to form a rotating groove 214. The limiting ring 212 is located in the mounting cavity 11, and the touch ring 213 is rotatably protruding from the connection port 14. The connection protrusion 15 is located in the rotating groove 214.

[0033] Furthermore, a limiting ring 212 is provided at the top and bottom of the rotating wheel 21, and a connecting protrusion 15 is provided at the top and bottom of the connecting hole. The touch ring 213 and the two limiting rings 212 respectively form two rotating grooves 214. The two rotating grooves 214 are located at the top and bottom of the rotating wheel 21 respectively. Therefore, there are two limiting rings 212, two connecting protrusions 15 and two rotating grooves 214. The two connecting protrusions 15 are respectively set in the two rotating grooves 214.

[0034] In use, first rotate the touch ring 213. The touch ring 213 drives the connecting shaft 211 to rotate, and the connecting shaft 211 drives the coupling 221 to rotate, so that the potentiometer 22 sends a speed regulation signal to the drive unit 13. The drive unit 13 receives the speed regulation signal and adjusts the speed of the stirring component 12 according to the speed regulation signal. During the process, the limiting ring 212 and the rotating groove 214 rotate with the touch ring 213, and the connecting protrusion 15 is always set in the rotating groove 214. In this way, when the limiting ring 212 is offset, the connecting protrusion 15 at the top or bottom of the connecting port 14 will abut against the limiting ring 212 at the corresponding position, so that the connecting protrusion 15 restricts the rotation trajectory of the touch ring 213 from the top and bottom of the connecting port 14, preventing the rotation of the touch ring 213 from not being converted into a change in the resistance value of the potentiometer 22 through the connecting shaft 211 and the coupling 221 due to position offset, thus causing speed regulation obstacles. Therefore, the setting of the connecting protrusion 15 and the limiting ring 212 improves the speed regulation stability.

[0035] To limit the rotation of the touch ring 213, the housing 1 is provided with a first limiting part, which is specifically a limiting area provided on the surface of the housing 1 and located on the left and right sides of the connection port 14. The rotating wheel 21 is provided with a corresponding second limiting part 215, which is specifically a limiting protrusion, and there are two of them. The two second limiting parts 215 are respectively provided at the two ends of the rotation direction of the touch ring 213, and the two ends of the touch ring 213 correspond to the maximum and minimum values ​​of the speed adjustment.

[0036] When the touch ring 213 is rotated, the second limiting part 215 rotates accordingly. When the touch ring 213 rotates to the end, the speed has reached the maximum or minimum value and cannot be adjusted to a larger or smaller value. At this time, the second limiting part 215 will abut against the first limiting part on the left or right side of the connection port 14 to prevent the touch ring 213 from continuing to rotate to the end that has been reached, thus preventing speed adjustment failure and improving speed adjustment stability.

[0037] To further improve speed regulation stability, a receiving cavity 216 is provided at the bottom of the rotor 21, and the connecting shaft 211 and the potentiometer 22 are both located in the receiving cavity 216.

[0038] Furthermore, the housing 1 is provided with a third limiting part 16, which is specifically a limiting strip protruding from the inner side of the housing 1. The top of the rotating wheel 21 is provided with a fourth limiting part 217, which is specifically a limiting rod. The fourth limiting part 217 and the third limiting part 16 limit and abut against each other to restrict the radial movement of the rotating wheel 21.

[0039] During the use of the whisk, the drive component 13 will vibrate, and the vibration will be transmitted to other components in the mounting cavity 11 through the housing 1. Therefore, after a long period of use, the potentiometer 22 and the rotating wheel 21 may be misaligned due to vibration. At this time, the receiving cavity 216 will limit the misalignment of the potentiometer 22, and the third limiting part 16 will limit the misalignment of the fourth limiting part 217 to prevent the connection between the coupling 221 and the connecting shaft 211 from becoming loose due to the misalignment of the potentiometer 22 and the rotating wheel 21, thereby causing speed regulation failure. Therefore, the setting of the receiving cavity 216 improves the positional accuracy of the potentiometer 22, and the setting of the third limiting part 16 and the fourth limiting part 217 improves the positional accuracy of the rotating wheel 21, thereby improving the stability of speed regulation.

[0040] Specifically, the drive unit 13 includes a circuit board 131 and a motor 132. The circuit board 131 and the potentiometer 22 are electrically connected so that the potentiometer 22 can send a speed regulation signal to the circuit board 131. The motor 132 is connected to the stirring unit 12, and the circuit board 131 is connected to the motor 132.

[0041] In use, when the connecting seat drives the coupling 221 to rotate, the potentiometer 22 sends a speed regulation signal to the circuit board 131. The circuit board 131 receives the signal and drives the motor 132 according to the speed regulation signal, so that the motor 132 drives the stirring piece 12 to rotate at different speeds. In the whole process, only the rotating wheel 21 is a mechanical component. The potentiometer 22, the circuit board 131 and the motor 132 are all connected by electronic signal transmission. Compared with mechanical speed regulation structures such as gear and fork types, the speed regulation process of this utility model is less prone to mechanical wear due to long-term use, thus avoiding speed regulation obstacles and other problems. While reducing the wear rate, it also improves the stability of speed regulation.

[0042] Furthermore, a mounting position 17 is provided inside the housing 1, and the circuit board 131 is disposed in the mounting position 17, and the mounting position 17 is disposed on the side of the housing 1 away from the stirring component 12.

[0043] During assembly, the circuit board 131 is located on the side of the housing 1 away from the mixing element 12. The rotary wheel 21 and potentiometer 22 are both located above the circuit board 131. The motor 132 is located between the mixing element 12 and the circuit board 131. In this way, the mixing element 12, the motor 132, the circuit board 131 and the potentiometer 22 are concentrated in the upper part of the whisk, which makes the wiring distance short, avoids vibration and wear of long wires and signal interference, and improves the stability of speed regulation.

[0044] Furthermore, when a user grips the whisk, they typically gather their five fingers together in the lower half of the whisk. Since the touch ring 213 is rotatably mounted on the side of the housing 1 opposite to the mixing element 12, and the lower half of the whisk is connected to the side of the upper half opposite to the mixing element 12, the touch ring 213 can be rotated by moving the thumb while maintaining the grip, making speed adjustment convenient and easy for one-handed operation. In addition, the main switch of this whisk is located in the lower half of the whisk, precisely at the position where the user's fingers touch when gripping it, allowing for easy one-handed operation of both power on / off and speed adjustment.

[0045] Specifically, the mixing component 12 includes mixing wires 121 and connecting rods 122. The housing 1 is provided with a connecting sleeve 18, which is located in the mounting cavity 11. One end of the connecting sleeve 18 is connected to the motor 132, and the other end is connected to the connecting rod 122. The mixing wires 121 are connected to the connecting rod 122 and are distributed at intervals on the connecting rod 122. Multiple mixing wires 121 are provided, all of which are used to mix food ingredients.

[0046] In use, potentiometer 22 sends a speed control signal to circuit board 131. After receiving the signal, circuit board 131 drives motor 132 to rotate connecting sleeve 18 at different speeds. Connecting sleeve 18 drives connecting rod 122 to rotate. Stirring wire 121 rotates in conjunction with connecting rod 122, so that stirring wire 121 rotates to stir food. The vibration force of motor 132 is relatively large when it starts. If it is directly transmitted to connecting rod 122, it is easy to cause connecting rod 122 to break. Therefore, connecting sleeve 18 is added between connecting rod 122 and motor 132. Connecting sleeve 18 drives connecting rod 122 to rotate. In this way, connecting sleeve 18 first distributes the vibration of motor 132 and then transmits the remaining vibration to connecting rod 122, reducing the burden on connecting rod 122, extending the service life of stirring component 12, and improving structural stability.

[0047] When a user rotates the rotary wheel 21, their hands may have some cooking ingredients on them, such as flour and oil, which reduces the friction between the hand and the rotary wheel 21 and makes it easy to slip. Therefore, multiple friction protrusions 2131 are set at intervals on the outer side of the touch ring 213 to increase the friction between the hand and the touch ring 213 and improve the convenience of speed adjustment.

[0048] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
