Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and in particular to a stirring head. Background Technology

[0002] With the rapid development of society and the economy, people's pace of life is getting faster and faster. Most wage earners prefer to eat at fast food restaurants and other popular dining options. Automatic cooking machines are widely used in fast food restaurants and other popular dining options to improve the efficiency of food preparation and reduce the workload of chefs. Whether an automatic cooking machine can produce delicious dishes depends not only on the movement of the wok itself but also on the automatic stirring and cooking mechanism.

[0003] Automatic stir-fry machines on the market are generally divided into two categories. One type uses the rotation of the pot to stir the food in the pot. This method is not only complex in structure, but also does not stir the food evenly or fully, thus prolonging the stirring time and causing the food to be of poor quality due to uneven heating. The other type uses a rotating spatula to stir the food in the pot. This type of stirring mechanism has a relatively simple structure, but the spatula area is small and it stirs in a fixed posture. When there is a lot of food in the pot, it is also difficult to stir the food fully, affecting the quality of the food.

[0004] The technical problem to be solved by this utility model is: how to solve the problem that existing stirring heads cannot fully stir the ingredients, thus affecting the quality of the dishes. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a stirring head with a simple and compact structure and thorough mixing.

[0006] The technical solution adopted by this utility model is as follows: a stirring head, including a stirring bridge and a stirring mechanism installed on the stirring bridge. The stirring mechanism includes a stirring power component, a stirring seat, a side shovel, and a stirring spade. The stirring power component is installed on the stirring bridge. The output shaft of the stirring power component is driven by an outer drive shaft and an inner drive shaft. The outer drive shaft is rotatably connected to the stirring bridge. The inner drive shaft is rotatably disposed inside the outer drive shaft. The stirring seat is fixedly connected to the outer drive shaft. The side shovel is connected to the side of the stirring seat. The stirring spade is disposed at the end of the stirring seat and passes through the stirring seat and is connected to the inner drive shaft.

[0007] The stirring head of this application is equipped with a side spatula and a stirring spatula, and the side spatula and the stirring spatula are driven to rotate independently by a stirring power component. During cooking, the ingredients in the pot can be thoroughly stirred at the same time, which can make the ingredients heat evenly, shorten the cooking time, improve the cooking efficiency, and make the dishes heat evenly, thus improving the quality of the dishes.

[0008] In some embodiments, the mixing shovel and the mixing seat are arranged at an angle, and the inner drive shaft is connected to the mixing shovel via a universal coupling.

[0009] By adopting the above technical solution, the stirring spatula rotates on its own axis while following the rotation of the stirring base, which allows the stirring spatula to change its own posture during the stirring process. This enables the ingredients in the pot to be stirred more thoroughly, resulting in more even heating, shorter cooking time, and improved product quality.

[0010] In some embodiments, the mixing shovel includes a mixing shaft and a mixing frame. One end of the mixing shaft is slidably connected to a universal coupling, and the other end is fixedly connected to the mixing frame. At least one main scraper is provided on the mixing frame.

[0011] By adopting the above technical solution, the stirring shaft and the coupling slide together, so that the main scraper keeps in contact with the inner wall of the pot, thereby ensuring that the food in the pot can be turned over, preventing sticking, and ensuring that the food is heated evenly.

[0012] In some embodiments, the universal coupling has a connecting shaft at one end near the stirring shaft, the stirring shaft has a sliding cavity for the connecting shaft to be inserted, the connecting shaft has a limiting groove at one end inserted into the sliding cavity, and a limiting member is provided on the stirring shaft, with the limiting member passing through the limiting groove.

[0013] By adopting the above technical solution, the limiting groove and the limiting component can limit the sliding distance of the stirring spatula, which can ensure that the main scraper keeps in contact with the pot wall and prevent the stirring head from getting stuck due to the stirring spatula extending too far.

[0014] In some embodiments, the stirring shaft and the connecting shaft are detachably connected by a limiting member.

[0015] Using the above technical solution, the mixing spatula can be quickly replaced as needed.

[0016] In some embodiments, the stirring bridge includes a base and a fixed sleeve, the fixed sleeve being disposed at one end of the base, and an outer drive shaft being rotatably connected to the fixed sleeve.

[0017] By adopting the above technical solution, the fixed sleeve can limit the runout of the external drive shaft, making the rotation of the external drive shaft more stable.

[0018] In some embodiments, the stirring bridge also includes a bracket and a fixed seat mounted on the base. The bracket is used to fix the stirring power component, and the fixed seat is located at one end of the bracket. The output shaft of the stirring power component is rotatably connected to the fixed seat.

[0019] By adopting the above technical solution, the bracket can facilitate the installation of the stirring power component, and the fixed seat can make the output shaft of the stirring power component rotate more smoothly.

[0020] In some embodiments, a first drive gear and a second drive gear are sequentially arranged on the output shaft of the stirring power unit along the axial direction, a first transmission gear that meshes with the first drive gear is arranged on the outer transmission shaft, and a second transmission gear that meshes with the second drive gear is arranged on the inner transmission shaft.

[0021] The above technical solution, which uses gear meshing transmission, features high transmission efficiency and precision, as well as a compact structure, making the stirring head more compact and energy-efficient.

[0022] In some embodiments, the inner drive shaft and the outer drive shaft are coaxially arranged, and the inner drive shaft and the outer drive shaft are arranged at an angle to the output shaft of the stirring power component. The first drive gear, the second drive gear, the first transmission gear and the second transmission gear are all bevel gears.

[0023] In some implementations, the side spatula and the mixing seat are detachably connected by fasteners.

[0024] By adopting the above technical solution, the side shovel can be quickly loaded, unloaded, or replaced as needed, making the operation more flexible and convenient. Attached Figure Description

[0033] Please see Figures 1 to 4 A preferred embodiment of the present invention provides a stirring head 100, comprising a stirring bridge 10 and a stirring mechanism 20 mounted on the stirring bridge 10. The stirring mechanism 20 includes a stirring power component 21, a stirring seat 22, a side shovel 23, and a stirring shovel 24. The stirring power component 21 is mounted on the stirring bridge 10. The output shaft of the stirring power component 21 is drivenly connected to an outer drive shaft 25 and an inner drive shaft 26. The outer drive shaft 25 is rotatably connected to the stirring bridge 10. The inner drive shaft 26 is rotatably disposed inside the outer drive shaft 25. The stirring seat 22 is fixedly connected to the outer drive shaft 25. The side shovel 23 is connected to the side of the stirring seat 22. The stirring shovel 24 is disposed at the end of the stirring seat 22 and passes through the stirring seat 22 to connect with the inner drive shaft 26. The stirring head 100 of this application is equipped with a side spatula 23 and a stirring spatula 24, and the side spatula 23 and the stirring spatula 24 are driven to rotate independently by the stirring power unit 21. During cooking, the ingredients in the pot can be stirred thoroughly at the same time, which can make the ingredients heat evenly, shorten the cooking time, improve the cooking efficiency, and make the dishes heat evenly, thus improving the quality of the dishes.

[0034] Preferably, such as Figures 1 to 3As shown, the stirring spatula 24 is set at an angle to the stirring base 22, and the inner drive shaft 26 is connected to the stirring spatula 24 via a universal coupling 27. The stirring spatula 24 rotates on its own axis while following the rotation of the stirring base 22, causing the stirring spatula 24 to change its own posture during the stirring process. This allows for more thorough stirring of the ingredients in the pot, resulting in more even heating, shorter cooking time, and improved product quality.

[0035] Furthermore, the stirring spatula 24 includes a stirring shaft 241 and a stirring frame 242. One end of the stirring shaft 241 is slidably connected to a universal coupling 27, and the other end is fixedly connected to the stirring frame 242. At least one main scraper 243 is provided on the stirring frame 242. The stirring shaft 241 and the universal coupling 27 are slidably engaged, so that the main scraper 243 keeps in contact with the inner wall of the pot, thereby ensuring that the food in the pot can be turned over, preventing sticking, and ensuring that the food is heated evenly.

[0036] Furthermore, such as Figure 3 and Figure 4 As shown, the universal coupling 27 has a connecting shaft 28 at one end near the stirring shaft 241. The stirring shaft 241 has a sliding cavity (not shown) for the connecting shaft 28 to be inserted into. The end of the connecting shaft 28 that is inserted into the sliding cavity has a limiting groove 281. A limiting member 244 is provided on the stirring shaft 241, and the limiting member 244 passes through the limiting groove 281. The limiting groove 281 and the limiting member 244 cooperate to limit the sliding distance of the stirring spatula 24, which can ensure that the main scraper 243 keeps in contact with the pot wall and prevent the stirring head 100 from getting stuck due to the stirring spatula 24 extending too far.

[0037] To facilitate loading and unloading of the mixing shovel 24, preferably, the mixing shaft 241 and the connecting shaft 28 are detachably connected by a limiting member 244.

[0038] Optionally, the limiting component 244 can be one of the fasteners such as a screw or a pin.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, the stirring bridge 10 includes a base 11 and a fixing sleeve 12. The fixing sleeve 12 is disposed at one end of the base 11, and the outer drive shaft 25 is rotatably connected to the fixing sleeve 12. The fixing sleeve 12 can limit the runout of the outer drive shaft 25, making the rotation of the outer drive shaft 25 more stable.

[0040] Preferably, to facilitate smoother rotation of the outer drive shaft 25, a first bearing (not shown) is provided between the fixed sleeve 12 and the outer drive shaft 25. Similarly, to facilitate smoother rotation of the inner drive shaft 26, a second bearing (not shown) is provided between the outer drive shaft 25 and the inner drive shaft 26, and a third bearing (not shown) and a fourth bearing (not shown) corresponding to the universal coupling 27 are respectively provided between the outer drive shaft 25 and the stirring base 22.

[0041] In one embodiment, the stirring bridge 10 further includes a bracket 13 and a fixing seat 14 mounted on the base 11. The bracket 13 is used to fix the stirring power component 21, and the fixing seat 14 is disposed at one end of the bracket 13. The output shaft of the stirring power component 21 is rotatably connected to the fixing seat 14. The bracket 13 facilitates the installation of the stirring power component 21, and the fixing seat 14 makes the rotation of the output shaft of the stirring power component 21 more stable.

[0042] Preferably, in order to reduce the resistance to the rotation of the stirring power component 21 and make its rotation smoother, a fifth bearing (not shown in the figure) is provided between the fixed base 14 and the output shaft of the stirring power component 21.

[0043] Optionally, to improve safety and make the stirring head 100 more aesthetically pleasing, the stirring bridge 10 also includes a cover plate 15, which covers the opening of the base 11, allowing the stirring power component 21 and the transmission component to be housed in the cavity formed by the cover plate 15 and the base 11.

[0044] In this embodiment, the stirring power component 21 is a motor. A first driving gear (not shown) and a second driving gear (not shown) are sequentially arranged along the axial direction on the output shaft of the stirring power component 21. A first transmission gear (not shown) meshing with the first driving gear is arranged on the outer transmission shaft 25, and a second transmission gear (not shown) meshing with the second driving gear is arranged on the inner transmission shaft 26. The use of gear meshing transmission has the characteristics of high transmission efficiency and precision, and a compact structure, making the stirring head 100 more compact and energy-efficient.

[0045] In other embodiments, other transmission mechanisms may be used for power transmission, such as synchronous pulleys and synchronous belts, sprockets and chains, etc.

[0046] Optionally, the inner drive shaft 26 and the outer drive shaft 25 are coaxially arranged, and the inner drive shaft 26 and the outer drive shaft 25 are arranged at an angle to the output shaft of the stirring power unit 21. The first drive gear, the second drive gear, the first transmission gear and the second transmission gear are all bevel gears.

[0047] Preferably, to ensure more even stirring during cooking, a speed difference can exist between the side spatula 23 and the stirring spatula 24. Furthermore, the rotational speed of the stirring spatula 24 should be greater than the rotational speed of the stirring base 22, because the stirring spatula 24, as the primary stirring component, is used to stir and tumble the ingredients at the bottom and middle of the pot, while the side spatula 23, as an auxiliary stirring component, mainly stirs and tumbles the ingredients in the upper middle part of the pot to prevent them from sticking to the pot walls.

[0048] To allow for quick installation, removal, or replacement of the side shovel 23 as needed, the side shovel 23 is detachably connected to the mixing base 22 via fasteners, making operation more flexible and convenient.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
