Description

Technical Field

[0001] This utility model relates to the field of dough mixers, and specifically discloses a dough mixer that can mix dough evenly. Background Technology

[0002] A dough mixer, a common household kitchen appliance, is mainly used to mix flour, water, and other ingredients into a smooth dough. It is widely used in homemade pasta making, such as steamed buns, dumplings, bread, and more. Currently, household dough mixers on the market are mainly divided into vertical and horizontal types, and most consist of a motor, a mixing paddle, and a mixing drum. However, existing household dough mixers still have the following problems in practical use:

[0003] 1. The lack of a lid design leads to flour splattering and hygiene issues:

[0004] Household dough mixers typically use an open mixing structure, which can cause flour to splatter during high-speed mixing, not only staining kitchen countertops but also wasting ingredients. Furthermore, the open design allows dust and foreign objects to fall into the dough, affecting food hygiene. Additionally, prolonged exposure to air causes the dough to dry out and harden, negatively impacting the kneading results.

[0005] 2. The method of fixing the agitator blades is inconvenient, making cleaning and replacement difficult:

[0006] Household dough mixers typically use blades bolted to or welded directly to the shaft, making disassembly cumbersome and difficult for ordinary users to do quickly. After prolonged use, dough residue can remain in the blade gaps, easily breeding bacteria and affecting food safety. Furthermore, fixed blades cannot be fitted with different shaped mixing heads to suit various dough-making needs (such as kneading, mixing, and whipping), reducing the equipment's practicality and flexibility.

[0007] Therefore, a dough mixer that can evenly mix dough is needed to solve this problem. Utility Model Content

[0008] This utility model proposes a dough mixer that can evenly mix dough. Through the design of a liftable and sealed cylinder cover and a spring-pressing mechanism, it can effectively prevent flour from splashing and maintain the moisture of the dough, thereby improving the hygiene and dough quality. In addition, the spring-clip quick-release design allows for tool-free disassembly and assembly of the mixing blades, which is convenient for cleaning and replacement, enhancing the ease of use and functionality.

[0009] This utility model is implemented as follows: a dough mixer that can mix dough evenly includes a base and a dough mixing drum. The upper end of the base is provided with an installation plate through a lifting mechanism. A stirring component is installed on the outer wall of the installation plate. A drum cover is provided on the lower side of the installation plate. A pressing mechanism is provided between the drum cover and the installation plate.

[0010] The clamping mechanism includes two limiting rods fixedly connected to the upper end face of the cylinder cover. The upper ends of the two limiting rods extend above the mounting plate and are fixedly connected to the limiting plate. The outer walls of the two limiting rods are sleeved with a first spring located between the cylinder cover and the mounting plate.

[0011] As a preferred embodiment of the present invention, the mixing assembly includes a drive motor mounted on the upper surface of the mounting plate. The output end of the drive motor extends to the lower part of the mounting plate and is fixedly connected to a first rotating shaft extending to the lower part of the cylinder cover. The lower end of the first rotating shaft is detachably connected to a second rotating shaft via a snap-fit ​​mechanism. A stirring blade is fixedly connected to the outer wall of the second rotating shaft.

[0012] As a preferred embodiment of the present invention, the dough kneading machine for uniform dough mixing includes a sliding groove inside the first rotating shaft, with two locking rods extending to the outside of the first rotating shaft slidably connected inside the sliding groove. A second spring is provided inside the sliding groove between the two locking rods. The locking mechanism also includes a cylinder fixedly connected to the upper end face of the second rotating shaft, with two first locking holes matching the locking rods through the outer wall of the cylinder.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0029] Please see Figure 1-4 A dough mixer that can mix dough evenly includes a base 1 and a dough mixing drum 2. The upper end of the base 1 is provided with a mounting plate 7 via a lifting mechanism. A stirring component is installed on the outer wall of the mounting plate 7. A drum cover 10 is provided on the lower side of the mounting plate 7. A pressing mechanism is provided between the drum cover 10 and the mounting plate 7.

[0030] The clamping mechanism includes two limiting rods 13 fixedly connected to the upper end face of the cylinder cover 10. The upper ends of the two limiting rods 13 extend above the mounting plate 7 and are fixedly connected to the limiting plate 15. The outer walls of the two limiting rods 13 are each sleeved with a first spring 14 located between the cylinder cover 10 and the mounting plate 7.

[0031] In this embodiment: the lifting mechanism drives the mounting plate 7 to move downward, thereby driving the mixing component to extend into the dough mixing drum 2 for dough mixing. When the mounting plate 7 moves downward, the limiting rod 13 and the limiting plate 15 drive the drum cover 10 to move downward and cover the dough mixing drum 2. When the mounting plate 7 continues to move downward, the first spring 14 presses the drum cover 10 tightly onto the dough mixing drum 2, ensuring that the drum cover 10 fits tightly with the dough mixing drum 2, preventing loosening during mixing, and improving stability. By setting the liftable drum cover 10, flour splashing is effectively prevented, raw material waste is reduced, kitchen cleanliness is maintained, and closed mixing reduces dust pollution. At the same time, it slows down the evaporation of dough moisture, making the dough more uniform and improving the quality of the dough.

[0032] As a technical optimization of this utility model, the stirring assembly includes a drive motor 8 installed on the upper surface of the mounting plate 7. The output end of the drive motor 8 extends to the lower part of the mounting plate 7 and is fixedly connected to a first rotating shaft 9 extending to the lower part of the cylinder cover 10. The lower end of the first rotating shaft 9 is detachably connected to a second rotating shaft 11 through a snap-fit ​​mechanism. The outer wall of the second rotating shaft 11 is fixedly connected to a stirring blade 12.

[0033] In this embodiment: the drive motor 8 is started, the drive motor 8 drives the first rotating shaft 9 to rotate, and then drives the second rotating shaft 11 to rotate through the snap-fit ​​mechanism. The second rotating shaft 11 further drives the stirring blade 12 to rotate, so as to stir the dough.

[0034] As a technical optimization of this utility model, the locking mechanism includes a groove 19 opened inside the first rotating shaft 9, two locking rods 20 extending to the outside of the first rotating shaft 9 are slidably connected inside the groove 19, and a second spring 21 located between the two locking rods 20 is provided inside the groove 19. The locking mechanism also includes a cylinder 18 fixedly connected to the upper end face of the second rotating shaft 11, and two first locking holes matching the locking rods 20 are opened through the outer wall of the cylinder 18.

[0035] In this embodiment: When disassembling the stirring blade 12, press the two locking rods 20 inward to disengage them from the first locking hole, thereby removing the cylinder 18 from the outer wall of the first rotating shaft 9. This allows the stirring blade 12 to be removed for cleaning or replacement. When installing the stirring blade 12, press the two locking rods 20 inward again. The two locking rods 20 slide relative to each other into the slide groove 19 and compress the second spring 21. The cylinder 18 is then fitted onto the outer wall of the first rotating shaft 9, and the locking rods 20 are aligned with the first locking hole. When the locking rods 20 are released, they slide outward under the elastic force of the second spring 21 and lock into the first locking hole, fixing the second rotating shaft 11 to the first rotating shaft 9, thereby fixing the stirring blade 12. The quick disassembly and assembly of the stirring blade 12 is achieved through the locking mechanism. Users can easily disassemble it without tools, making cleaning convenient and preventing bacterial growth.

[0036] As a technical optimization of this utility model, the lifting mechanism includes a sleeve 3 fixedly connected to the upper end face of the base 1, a column 4 slidably connected inside the sleeve 3, a mounting plate 7 fixedly connected to the upper end face of the column 4, a servo motor 5 installed inside the sleeve 3, and a threaded rod 6 threadedly connected to the column 4 at the output end of the servo motor 5.

[0037] In this embodiment: the servo motor 5 is started, and the servo motor 5 drives the threaded rod 6 to rotate, which in turn drives the column 4 to move up or down along the sleeve 3, thereby driving the stirring assembly and the cylinder cover 10 to rise and fall.

[0038] As a technical optimization of this utility model, the lower end face of the dough mixing cylinder 2 is fixedly connected to a sliding plate 16 that is slidably connected to the base 1. The outer wall of the base 1 is threaded with two fixing bolts 17, and the outer wall of the sliding plate 16 is provided with two second locking holes that match the fixing bolts 17.

[0039] In this embodiment: by inserting the fixing bolt 17 into the second locking hole, the slide plate 16 is easily fixed, thereby fixing the dough mixing cylinder 2, which facilitates the installation and disassembly of the dough mixing cylinder 2.

[0040] As a technical optimization of this utility model, heat dissipation holes are provided on the outer wall of the sleeve 3.

[0041] In this embodiment, heat dissipation holes are opened on the outer wall of the sleeve 3 to facilitate heat dissipation of the servo motor 5.

[0042] As a technical optimization of this utility model, the outer wall of the sleeve 3 is provided with a control panel, and the servo motor 5 and the drive motor 8 are both electrically connected to the control panel.

[0043] In this embodiment, the servo motor 5 and drive motor 8 can be easily controlled to operate normally via the control panel.

[0044] The working principle and usage process of this utility model are as follows: First, flour and water are poured into the mixing drum 2. Then, the servo motor 5 is started. The servo motor 5 drives the threaded rod 6 to rotate, which in turn drives the column 4 to move downwards along the sleeve 3. The column 4 further drives the mounting plate 7 to move downwards, thereby causing the mixing assembly to extend into the mixing drum 2. When the mounting plate 7 moves downwards, the limiting rod 13 and the limiting plate 15 drive the drum cover 10 to move downwards and cover the mixing drum 2. As the mounting plate 7 continues to move downwards, the first spring 14 presses the drum cover 10 tightly onto the mixing drum 2. Then, the drive motor 8 is started. The drive motor 8 drives the first rotating shaft 9 to rotate, which in turn drives the second rotating shaft 11 to rotate through the snap-fit ​​mechanism. The second rotating shaft 11 further... The mixing blade 12 is rotated to mix the dough. When disassembling the mixing blade 12, the two locking rods 20 are pressed inward to disengage them from the first locking hole, allowing the cylinder 18 to be removed from the outer wall of the first rotating shaft 9. The mixing blade 12 can then be removed for cleaning or replacement. When installing the mixing blade 12, the two locking rods 20 are pressed inward again, causing them to slide into the groove 19 and compress the second spring 21. The cylinder 18 is then fitted onto the outer wall of the first rotating shaft 9, and the locking rods 20 are aligned with the first locking hole. The locking rods 20 are released, and under the elastic force of the second spring 21, they slide outward and lock into the first locking hole, fixing the second rotating shaft 11 to the first rotating shaft 9, thereby fixing the mixing blade 12.
