Description

Technical Field

[0001] The present invention relates to the technical field of egg beaters, and specifically to a stepless variable-speed egg beater capable of manual adjustment. Background Art

[0002] During the process of bread production, eggs need to be whipped before use. Manual egg beating is inefficient, laborious and not safe and hygienic enough. In order to save time and effort, a variable-speed electric egg beater is used during egg beating. Generally, egg beaters are used in the kitchen. However, in the kitchen, in addition to eggs that need to be stirred, there are other ingredients that also need to be stirred, such as fruit juice or flour and other ingredients that need to be stirred.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present invention provides a stepless variable-speed egg beater capable of manual adjustment, having the following beneficial effects:

[0016] 1. For the stepless variable-speed egg beater capable of manual adjustment, by providing an installation mechanism, the stirring rod can be adjusted and replaced correspondingly under different usage conditions, thereby improving the practicability of the egg beater, avoiding the need to use different models of stirrers, ensuring the practical value of the egg beater. At the same time, the installation mechanism is relatively simple for installing or disassembling the stirring rod, which reduces the installation force of the user when adjusting and replacing the stirring rod, improves the speed of installing or removing the stirring rod, and improves the use efficiency of the egg beater.

[0017] 2. The stepless variable speed egg beater that can be manually adjusted has a "cross"-shaped installation tenon block, which ensures the sealing performance of the connection between the installation tenon block and the installation tenon groove, thereby increasing the firmness of the connection between the stirring rod and the egg beater housing, avoiding the loosening of the installation tenon block when the stirring rod rotates, and improving the stability of the stirring rod during use.

[0018] 3.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-8 , the present invention provides a new technical solution: a stepless variable speed egg beater that can be manually adjusted, including an egg beater housing 1. A stirring rod 2 is provided at the left end of the egg beater housing 1. The stirring rod 2 is a conventional structure and will not be described in detail. The shape of the stirring rod used in different environments is different. For example Figure 5 lists two different shapes of the stirring rod 2, but the shape of the stirring rod 2 is not limited to Figure 5There are two stirring rods 2 of different shapes, and there are also other different styles of stirring rods 2, so that the stirring rods 2 can be replaced correspondingly in different environments. A motor 3 is fixedly connected inside the egg beater housing 1. A gearbox 4 is arranged at the left end of the motor 3, and the input shaft of the gearbox 4 is fixedly connected to the output shaft of the motor 3. The gearbox 4 and the motor 3 are existing structures and will not be elaborated too much. A storage battery 5 is fixedly connected inside the egg beater housing 1. The storage battery 5 is an existing structure and will not be elaborated too much. The storage battery 5 is respectively connected to the motor 3 and the gearbox 4 through external wires. And a PCB board 6 is arranged inside the egg beater housing 1. The PCB board 6 is connected to the gearbox 4 and the motor 3 respectively through signal lines. A power switch 7 is arranged on the right surface of the grip part of the egg beater housing 1. The power switch 7 is an existing structure and will not be elaborated too much. And the power switch 7 is connected to the PCB board 6 through a signal line. A gear shift key 8 is arranged on the left surface of the grip part of the egg beater housing 1. The gear shift key 8 is also connected to the PCB board 6 through a signal line. In this way, the power switch 7 controls the motor 3, and the gear shift key 8 controls the gearbox 4;

[0033] A connecting rod 10 is fixedly connected to the right end of the stirring rod 2. An installation tenon block 11 is movably sleeved on the connecting rod 10, and the form of the installation tenon block 11 is set as a "cross" shape. At the same time, the right end of the connecting rod 10 extends into the right surface of the installation tenon block 11. An installation tenon groove 12 that matches the installation tenon block 11 is opened on the left surface of the egg beater housing 1. The installation tenon groove 12 communicates with the inside of the egg beater housing 1. In this way, the stirring rod 2 is spliced on the installation tenon groove 12 of the egg beater housing 1 through the installation tenon block 11. In this way, the right end of the connecting rod 10 extends into the inside of the egg beater housing 1. By setting the installation tenon block 11 as a "cross" shape, the tightness of the connection between the installation tenon block 11 and the installation tenon groove 12 is ensured, thereby increasing the firmness of the connection between the stirring rod 2 and the egg beater housing 1, avoiding the loosening of the installation tenon block 11 when the stirring rod 2 rotates, and improving the stability of the stirring rod 2 during use;

[0034] A docking block 13 is fixedly connected to the right end of the connecting rod 10, and the structure of the docking block 13 is set as a regular triangular pyramid. A connecting shaft 9 is fixedly connected to the output shaft of the gearbox 4. The connecting shaft 9 does not contact the inner wall of the egg beater housing 1. A docking groove 14 that matches the docking block 13 is provided on the left surface of the connecting shaft 9. Thus, the connecting rod 10 is spliced with the docking block 13 and the docking groove 14. In this way, the power generated by the motor 3 is driven by the output shaft of the gearbox 4 to rotate out, so that the connecting shaft 9 rotates. In this way, the connecting rod 10 rotates synchronously under the restriction of the docking block 13 and the docking groove 14, thereby driving the stirring rod 2 to rotate. By setting the docking block 13 as a regular triangular pyramid, the situation that the docking block 13 and the docking groove 14 are misaligned is avoided, ensuring the stability when the docking block 13 and the docking groove 14 are spliced, and improving the efficiency of the device when replacing the stirring rod;

[0035] Three groups of limit sliders 16 are respectively fixedly connected to one end of the connecting rod 10 located inside the installation tenon block 11. The number of one group of limit sliders 16 is four. The four limit sliders 16 are respectively fixedly connected to the outer surface of the connecting rod 10 in a form of rotating 90 degrees. The limit sliders 16 are set as spherical. Three limit sliding grooves 15 that match the limit sliders 16 are respectively provided on the inner ring of the installation tenon block 11. Thus, the limit sliders 16 are slidably connected with the limit sliding grooves 15. In this way, when the connecting rod 10 rotates on the installation tenon block 11, the limit sliders 16 slide in the limit sliding grooves 15. By setting the limit sliders 16 as spherical, the smoothness of the contact surface between the limit sliders 16 and the limit sliding grooves 15 is increased, thereby reducing the friction formed when the limit sliders 16 slide, ensuring the stability when the connecting rod 10 rotates. At the same time, the limit sliders 16 and the limit sliding grooves 15 have a limiting effect, so that the situation that the connecting rod 10 and the installation tenon block 11 are separated is avoided, and the firmness of the stirring rod 2 during use is improved;

[0036] An internal movable groove 17 is formed in the left wall of the egg beater housing 1. The lower end of the internal movable groove 17 communicates with the vertical groove at the upper end of the installation tenon groove 12. A locking rod 18 is arranged in the internal movable groove 17. The lower end of the locking rod 18 extends into the installation tenon groove 12 through the internal movable groove 17. A locking groove 19 is formed on the upper surface of the vertical plate at the upper end of the installation tenon block 11. Thus, the locking rod 18 is clamped with the locking groove 19. A through chute 20 communicating with the internal movable groove 17 is formed on the left side surface of the egg beater housing 1. A push rod 21 is fixedly connected to the outer surface of the locking rod 18. The left end of the push rod 21 extends out of the egg beater housing 1 through the through chute 20, and the push rod 21 is slidably connected with the through chute 20. In this way, the up and down displacement of the locking rod 18 can be controlled by pushing the push rod 21. The lower end of the locking rod 18 is hemispherical, and an inclined surface is arranged on the vertical plate at the upper end of the installation tenon block 11. Thus, when the installation tenon block 11 extends into the installation tenon groove 12 from left to right, the inclined surface on the installation tenon block 11 contacts the lower end of the locking rod 18. Thus, the locking rod 18 moves upward along the inclined surface of the installation tenon block 11, and thus the locking rod 18 contracts into the internal movable groove 17. When the locking rod 18 and the locking groove 19 are at the same horizontal position, the locking rod 18 falls into the locking groove 19 under the action of inertia. In this way, the fixing of the installation tenon block 11 is completed. The lower end of the locking rod 18 is set to be hemispherical, which reduces the friction force formed when the locking rod 18 contacts the inclined surface of the installation tenon block 11, avoids the mechanical jamming of the locking rod 18, and thus ensures the smoothness of the locking rod 18 during operation;

[0037] Two control grooves 22 are respectively formed in the left and right inner walls of the internal movable groove 17. The control grooves 22 are located below the through chute 20. Two control sliding plates 23 respectively extending into the two control grooves 22 are fixedly connected to the outer surface of the locking rod 18. A chute is formed at one end of the control sliding plate 23 located in the control groove 22. A control sliding rod 24 slidably connected with the control sliding plate 23 is fixedly connected in the control groove 22. Both ends of the control sliding rod 24 are fixedly connected to the upper and lower inner walls of the control groove 22. A control spring 25 movably sleeved on the control sliding rod 24 is fixedly connected to the upper surface of the control sliding plate 23. The upper end of the control spring 25 is fixedly connected to the top inner wall of the control groove 22. In this way, when the locking rod 18 moves up and down, it drives the control sliding plate 23 to slide on the control sliding rod 24, and at the same time squeezes or stretches the control spring 25. In this way, the stability of the clamping between the locking rod 18 and the locking groove 19 in any case is ensured, the practicability of the device is improved. At the same time, the control sliding plate 23 slides on the control sliding rod 24, which avoids the shaking of the locking rod 18 during sliding and improves the accuracy of clamping with the locking groove 19.

[0038] Working principle: When a stepless variable-speed egg beater that can be manually adjusted needs to manually adjust different stirring rods 2, when the stirring rod 2 drives the installation tenon block 11 to extend from left to right into the installation tenon groove 12, the inclined surface on the installation tenon block 11 contacts the lower end of the locking rod 18, so that the locking rod 18 moves upward along the inclined surface of the installation tenon block 11, so that the locking rod 18 contracts into the built-in movable groove 17, and at the same time, the control spring 25 contracts. When the locking rod 18 and the locking groove 19 are at the same horizontal position, the locking rod 18 drops into the locking groove 19 under the action of the resilience of the control spring 25, thus completing the fixation of the stirring rod 2;

[0039] When it is necessary to remove the stirring rod 2, only need to control the upward displacement of the locking rod 18 through the push rod 21, so that the contact between the locking rod 18 and the locking groove 19 is lost, and thus the stirring rod 2 can be removed.

[0040] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
