Technical Field

[0001] The utility model relates to the field of food blenders, in particular to a hand-held stirring rod with stepless speed regulation. Background Technique

[0002] A food blender is a kitchen appliance that can quickly and efficiently stir and mix food and liquids. It is very suitable for making fruit juices, milkshakes, baked goods, etc. It is a useful assistant in the kitchen. It is easy to operate and clean, and there are various types to adapt to different stirring requirements and material characteristics. When purchasing, consumers should choose a suitable brand and model according to their own needs. When using, they need to follow the instructions to ensure correct and safe operation. The food blender not only improves cooking efficiency but also makes the food taste better. It is an indispensable electrical appliance in modern kitchens.

[0003] At present, for the food blenders on the market, their speed regulation and switch control are not concentrated in one place. This design configuration has obvious deficiencies. Taking traditional food blenders as an example, users usually need to preset the stirring speed first and then start the machine through a button. However, this method limits the possibility for users to adjust the stirring speed at any time during the operation of the machine, thus affecting the fine control of food processing effect and efficiency. In short, the existing design restricts the flexibility and real-time nature of operation, making it impossible for users to dynamically adjust performance parameters during the operation of the machine to achieve the best food processing effect. Content of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide a hand-held stirring rod with stepless speed regulation to solve the technical problem that its speed regulation device and switch device are not concentrated at the button and the working speed cannot be adjusted at any time while the machine is working.

[0005] To achieve the above object, the present utility model provides the following technical solution: A hand-held stirring rod with stepless speed regulation, including a left cover, a right cover and an axis. One side of the left cover is embedded with a button, and a first spring is arranged on one side of the button. The left cover is snap-fitted with the right cover. One end of the button is provided with a push rod, and a second spring is arranged on the outer side of the push rod. The push rod is embedded in the inner side of the right cover. An electronic board is arranged between the left cover and the right cover. A potentiometer is arranged on the electronic board, and a dial rod is arranged on one side of the potentiometer. The push rod abuts against the dial rod.

[0006] By adopting the above technical solution, when the user presses the button, the button will push the push rod to move back and forth inside the right cover. This movement causes the push rod to move and toggle the switch, thereby turning on the switch and then starting the motor, making the blender start to work.

[0007] Furthermore, a switch is provided on one side of the potentiometer. The switch is fixedly welded to the electronic board, and the electronic board is snap-fitted with the right cover.

[0008] By adopting the above technical solution, the switch provided on one side of the potentiometer can conveniently control the power on and off of the stirrer. Since the switch is fixedly welded to the electronic board, the stability and reliability of the circuit connection are enhanced, and the risk of failures caused by poor connection is reduced.

[0009] Furthermore, a motor is provided below the inner sides of the left cover and the right cover. The output end of the motor is sleeved with the axis through a connector, and a stirring blade is provided at the bottom end of the axis.

[0010] By adopting the above technical solution, the motor provided below the inner sides of the left cover and the right cover provides a powerful power source for the stirrer. The position of the motor is reasonably set, which not only ensures its stable operation but also facilitates the dissipation of heat, contributing to the extension of the service life of the motor.

[0011] Furthermore, the first spring and the second spring are used to provide the elastic reset property of the button and the ejector rod.

[0012] By adopting the above technical solution, after the user presses the button, the elastic force of the first spring will cause the button to return to its original position, which can ensure that the button can automatically reset after each use, facilitating the next operation.

[0013] Furthermore, the button, the left cover, the ejector rod, the right cover, and the connector are made of engineering plastics. The first spring, the second spring, the axis, and the stirring blade are made of stainless steel. The potentiometer is electrically connected to an external power supply through the electronic board.

[0014] By adopting the above technical solution, the engineering plastic material has the characteristics of being light, durable, and corrosion-resistant, which can reduce the overall weight of the stirrer, improve the portability, and at the same time ensure the stability and durability of the structure. In addition, the potentiometer is electrically connected to an external power supply through the electronic board, ensuring a stable power supply, enabling the stirrer to work continuously and stably, improving the reliability and safety of the stirrer, and providing a better user experience for users.

[0015] In summary, the present utility model mainly has the following beneficial effects:

[0016] In this utility model, through a push rod, a potentiometer, and an electronic board, when the user presses the button, the button will push the ejector rod to reciprocate inside the right cover. This movement causes the ejector rod to move and toggle the switch, thereby turning on the switch and starting the motor, making the blender start working. At the same time, the reciprocating movement of the ejector rod will also drive the lever of the potentiometer to move, thereby changing the resistance value of the potentiometer. This change in resistance value will affect the voltage output by the electronic board to the motor, resulting in a change in the motor speed. The motor further drives the change in the rotation speed of the mixing blade through the connector and the axis. This series of linkage designs enable the user to simultaneously start the blender and adjust the speed with a single button operation, significantly improving the usability of the food blender.

The embodiments described below by referring to the drawings are exemplary and are only used to explain this utility model and should not be construed as a limitation of this utility model.

[0021] Next, the embodiments of this utility model will be described according to its overall structure.

[0022] A hand-held stirring rod with stepless speed change, such as Figure 1 - Figure 2As shown in the figure, it includes a left cover 3, a right cover 9 and an axis 12. One side of the left cover 3 is embedded with a button 1. One side of the button 1 is provided with a first spring 2. The left cover 3 is snap-connected to the right cover 9. One end of the button 1 is provided with a push rod 4. A second spring 5 is arranged outside the push rod 4. The push rod 4 is embedded in the inner side of the right cover 9. An electronic board 8 is arranged between the left cover 3 and the right cover 9. A potentiometer 7 is arranged on the electronic board 8. A toggle lever is arranged on one side of the potentiometer 7. The push rod 4 abuts against the toggle lever. When the user presses the button 1, the button 1 will push the push rod 4 to move back and forth inside the right cover 9. This movement causes the push rod 4 to move and toggle the switch 6, thereby turning on the switch 6, and then starting the motor 10, making the stirrer start to work. At the same time, the reciprocating movement of the push rod 4 drives the toggle lever of the potentiometer 7 to move. This movement will change the resistance value of the potentiometer 7. The change in the resistance value will affect the voltage output by the electronic board 8 to the motor 10, further causing the rotation speed of the motor 10 to change. The motor 10 drives the rotation speed of the stirring blade 13 to change correspondingly through the connector 11 and the axis 12.

[0023] Refer to Figure 1 、 Figure 2 As shown in the figure, a switch 6 is arranged on one side of the potentiometer 7. The switch 6 is welded and fixed to the electronic board 8. The electronic board 8 is snap-connected to the right cover 9. The switch 6 arranged on one side of the potentiometer 7 can conveniently control the on-off of the power supply of the stirrer. Since the switch 6 is welded and fixed to the electronic board 8, the stability and reliability of the circuit connection are enhanced, and the risk of failure caused by poor connection is reduced. At the same time, the electronic board 8 is snap-connected to the right cover 9. This structure makes the installation of the electronic board 8 more firm and not easily loosened or damaged due to vibration or impact. This stable installation method helps to protect the electronic components, thereby extending the service life of the stirrer.

[0024] Refer to Figure 1 、 Figure 2 As shown in the figure, a motor 10 is arranged below the inner sides of the left cover 3 and the right cover 9. The output end of the motor 10 is sleeved with the axis 12 through a connector 11. A stirring blade 13 is arranged at the bottom end of the axis 12. The motor 10 arranged below the inner sides of the left cover 3 and the right cover 9 provides a powerful power source for the stirrer. The position of the motor 10 is set reasonably, which not only ensures its stable operation but also facilitates the dissipation of heat, helping to extend the service life of the motor 10. At the same time, the output end of the motor 10 is sleeved with the axis 12 through a connector 11. This connection method ensures the stability and efficiency of power transmission. The stirring blade 13 at the bottom end of the axis 12 can efficiently complete the food stirring task, and its design and material selection ensure both the stirring effect and durability.

[0025] Refer to Figure 1 、 Figure 2, the first spring 2 and the second spring 5 are used to provide elastic reset for the button 1 and the ejector rod 4. When the user presses the button 1, the elastic force of the first spring 2 will cause the button 1 to return to its original position. This can ensure that the button 1 automatically resets after each use, facilitating the next operation. At the same time, the second spring 5 provides elastic reset for the ejector rod 4. After the ejector rod 4 is pushed by the button 1 to move reciprocally, the second spring 5 will use its elastic force to reset the ejector rod 4. This can ensure that the ejector rod 4 accurately returns to its initial position after each operation, ensuring the stability of the device and the accuracy of the next operation.

[0026] Refer to Figure 1 , Figure 2 , the materials of the button 1, the left cover 3, the ejector rod 4, the right cover 9, and the connector 11 are engineering plastics, and the materials of the first spring 2, the second spring 5, the shaft center 12, and the stirring blade 13 are stainless steel. The potentiometer 7 is electrically connected to an external power supply through an electronic board 8. The engineering plastic material has the characteristics of being light, durable, and corrosion-resistant, which can reduce the overall weight of the stirrer, improve portability, and at the same time ensure the stability and durability of the structure. At the same time, the stainless steel material has high hardness and corrosion resistance, which can ensure that these components maintain excellent elasticity and cutting performance during long-term use, improving the service life and stirring effect of the stirrer.

[0027] The implementation principle of the present utility model is as follows: The button 1 is installed in the column hole of the left cover 3 through the first spring 2. First, when the button 1 is pressed, the button 1 pushes the ejector rod 4 to move reciprocally inside the right cover 9. The ejector rod 4 moves in position, toggles the switch 6, and makes the switch 6 closed. Then the motor 10 of the machine starts to work. At the same time, the reciprocating movement drives the lever of the potentiometer 7 to move in position, thereby changing the resistance value of the potentiometer 7, causing the voltage output by the electronic board 8 to the motor 10 to change, and thus changing the rotation speed of the motor 10. The motor 10 drives the rotation speed of the stirring blade through the connector 11 and the shaft center 12, thereby improving the convenience of use of the food stirrer.

[0028] Parts not involved in the present utility model are the same as or can be implemented by using the prior art, and will not be elaborated here.
