Description

Technical Field

[0001] The utility model relates to the technical field of microwave stirring motors, in particular to a gear-driven microwave stirring motor mechanism. Background Art

[0002] A microwave stirring motor is an electric device that combines microwave heating and mechanical stirring functions, and is widely used in fields such as chemical industry, pharmaceuticals, and food processing. Its main function is to evenly distribute heat through mechanical stirring while microwave radiation penetrates the material and directly acts on the molecular structure of the material, enabling the material to be heated evenly during the microwave heating process, avoiding phenomena such as local overheating or uneven heating. In scenarios such as chemical reactions, drug synthesis, and food heating processes, the microwave stirring motor can significantly improve the heating efficiency, shorten the processing time, and ensure the quality and stability of the product. Its application scenarios also include installation in laboratory reactors, microwave extraction equipment, etc., and are particularly suitable for gentle and uniform heating of heat-sensitive materials.

[0003] The existing microwave stirring motor disrupts the microwave generated by the waveguide box through a stirrer, so that the microwave can be evenly distributed in the cavity of the microwave oven, and the microwave radiation penetrates the material and directly acts on the molecular structure of the material, enabling it to quickly heat up and accelerate the reaction process, and can achieve rapid and uniform heating and mixing of the material, reducing energy consumption and improving the stability of the process and the consistency of the product.

[0004] However, most of the existing microwave stirring motors adopt a direct drive design. Although this structure simplifies the transmission process between the motor and the stirrer, since the direct drive motor is directly installed inside the microwave cavity, the motor is inevitably exposed to the high-temperature environment generated inside the cavity and cannot effectively isolate the heat derived from the microwave heating process. This causes the high temperature inside the cavity to directly affect the normal operation of the motor, resulting in overheating of the motor, and further affecting its service life and operating efficiency. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the deficiencies existing in the prior art, and to propose a gear-driven microwave stirring motor mechanism, aiming to improve the problem that most of the existing microwave stirring motors are direct drive type and cannot reduce the influence of the heat derived from the inside of the cavity on the motor.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A gear-driven microwave stirring motor mechanism is installed on a cavity assembly.

[0009] Further, an outer wall of the cavity assembly is fixedly connected to a second support bracket, and the outer wall of the second support bracket is fixedly connected to the outer wall of the motor bracket.

[0010] Further, an outer wall of the motor bracket is fixedly connected to a gear cover, and both the driving gear and the driven gear are arranged inside the gear cover.

[0011] Further, the outer wall of the motor shaft is rotatably connected to the inside of the gear cover, and the outer wall of the stirring shaft is rotatably connected to the inside of the gear cover.

[0013] Further, the stirrer is arranged inside the cavity assembly, and the outer wall of the support frame is fixedly connected to the inside of the cavity assembly.

[0014] The present utility model has the following beneficial effects:

[0015] 1.

In the present utility model, by installing the driving gear and the driven gear between the gear cover and the motor bracket, the loosening of the driving gear and the driven gear can be effectively prevented. At the same time, the cooperation of the bracket support one and the bracket support two can well support the motor bracket and the motor body, thereby stabilizing the overall structure, improving the stability of the motor, and ensuring the use safety of the motor.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 6 , an embodiment provided by the present utility model is: a gear transmission microwave stirring motor mechanism is installed on the cavity component 1. The outer wall of the cavity component 1 is fixedly connected with a waveguide box component 2. The outer wall of the waveguide box component 2 is fixedly connected with a motor bracket 3. The outer wall of the motor bracket 3 is fixedly connected to the outer wall of the cavity component 1. The motor bracket 3 is installed and fixed at the bottom of the cavity component 1 through the waveguide box component 2, so as to stabilize the position of the motor bracket 3. The outer wall of the motor bracket 3 is fixedly connected with a motor body 5. The output end of the motor body 5 is fixedly connected with a motor shaft 11. The motor body 5 is fixed through the motor bracket 3, so that the motor body 5 can be stably installed at the bottom of the cavity component 1 and at the same time drive the motor shaft 11 to rotate. The outer wall of the motor shaft 11 is fixedly connected with a driving gear 6. A driven gear 8 is arranged on the outer wall of the motor bracket 3. The driving gear 6 meshes with the driven gear 8. The output end of the motor body 5 drives the motor shaft 11 to drive the driving gear 6 to rotate. When the driving gear 6 rotates, through the meshing between the gears, the rotational power is transmitted to the driven gear 8, causing it to start rotating. The inner part of the driven gear 8 is fixedly connected with a stirring shaft 9. The outer wall of the stirring shaft 9 is fixedly connected with a bearing 10. The driven gear 8 drives the stirring shaft 9 connected to its inside to rotate, effectively avoiding the direct contact between the stirring shaft 9 and the output end of the motor body 5 and reducing the direct transfer of heat. The bearing 10 ensures that the stirring shaft 9 runs smoothly when rotating inside the motor bracket 3, preventing jamming caused by increased friction or poor movement, and improving the operating stability of the motor. The outer wall of the stirring shaft 9 is fixedly connected with a stirrer 13. The outer wall of the stirrer 13 is fixedly connected with a support frame 14; the stirrer 13 is stably fixed through the support frame 14, so that the stirrer 13 can be well supported inside the cavity component 1, thereby ensuring the normal operation of the stirrer 13. The outer wall of the motor shaft 11 is rotatably connected inside the motor bracket 3. The outer wall of the bearing 10 is fixedly connected inside the motor bracket 3; through the bearing 10, the friction between the stirring shaft 9 and the motor bracket 3 can be reduced, thereby extending the service life of the motor bracket 3. The outer wall of the stirring shaft 9 is rotatably connected inside the cavity component 1. The outer wall of the stirring shaft 9 is rotatably connected inside the support frame 14;

[0027] Referring toFigure 3 - Figure 6 On the outer wall of the waveguide box assembly 2, a first support bracket 4 is fixedly connected, and the outer wall of the first support bracket 4 is fixedly connected to the outer wall of the motor bracket 3. The first support bracket 4 can effectively provide support for the motor bracket 3 and the motor body 5, enhancing the stability of the motor bracket 3. On the outer wall of the cavity assembly 1, a second support bracket 12 is fixedly connected, and the outer wall of the second support bracket 12 is fixedly connected to the outer wall of the motor bracket 3. The second support bracket 12 firmly fixes the motor bracket 3 on the outer wall of the waveguide box assembly 2, preventing the negative impact of the vibration generated during the operation of the motor body 5 on the overall structure. On the outer wall of the motor bracket 3, a gear cover 7 is fixedly connected. The driving gear 6 and the driven gear 8 are both arranged inside the gear cover 7. The gear cover 7 provides effective protection for the driving gear 6 and the driven gear 8, resisting potential interference from the external environment to these key gears. The outer wall of the motor shaft 11 is rotatably connected inside the gear cover 7, and the outer wall of the stirring shaft 9 is rotatably connected inside the gear cover 7. The gear cover 7 also plays a role in isolating the heat inside the cavity assembly 1, thus preventing the heat from directly being transferred from the stirring shaft 7 and the motor shaft 11 to the motor body 5. This not only reduces the heat burden of the stirring shaft 9 on the motor body 5 but also effectively prevents the overheating problem of the motor body 5. The stirrer 13 is arranged inside the cavity assembly 1, and the outer wall of the support frame 14 is fixedly connected inside the cavity assembly 1. The stirrer 13 improves the uniformity of the microwave distribution in the oven cavity by disturbing the microwaves generated in the waveguide box, ensuring that the food can be heated evenly, so that the microwaves act more evenly on each part of the food, improving the heating effect, while the support frame 14 is used to support the stirrer 13 as a whole.

[0028] Working principle: When it is necessary to reduce the heat transferred from the stirring shaft 9 to the motor body 5, the motor shaft 11 is driven by the output end of the motor body 5 to drive the driving gear 6 to rotate, so that the driving gear 6 can drive the driven gear 8 to rotate together, and then drive the stirring shaft 9 inside the driven gear 8 to rotate, thus preventing the stirring shaft 9 from directly contacting the output end of the motor body 5. Among them, the bearing 10 can prevent the stirring shaft 9 from getting stuck when rotating inside the motor bracket 3, and the gear cover 7 can protect the driving gear 6 and the driven gear 8, thus preventing the heat of the cavity assembly 1 from being directly transferred to the motor, which may lead to the temperature rise of the motor, improving the practicability of the motor and extending the service life of the motor. When it is necessary to reinforce the overall structure of the motor, the first support bracket 4 and the second support bracket 12 can support the motor bracket 3 and the motor body 5, so that the motor bracket 3 can be more firmly installed on the outer wall of the waveguide box assembly 2. At the same time, the gear cover 7 can provide necessary protection for the driving gear 6 and the driven gear 8, thus preventing interference from external factors to the driving gear 6 and the driven gear 8, thereby stabilizing the overall structure and ensuring the safe use of the motor.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
