[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1 , Figure 2 and Figure 3 The manual-automatic integrated mixer shown in the figure comprises a barrel 1 and a barrel cover 2 threadedly connected to the barrel 1. The barrel 1 of the device is arranged as a cylindrical rotating body to facilitate fastening with the barrel cover 2. An inverted concave frame 11 is arranged on the barrel cover 2, and an electric motor 12 is arranged below the concave frame 11. A driving gear 13 is connected to the rotating shaft of the electric motor 12 as the power output during automatic stirring. A socket 6 is arranged at the center of the barrel cover 2, and a stirring rod 14 is arranged to rotate and slide in the socket 6. A stirring blade 16 is arranged at the bottom of the stirring rod 14, and the stirring blade 16 is located in the barrel 1. In this way, when in use, low-frequency manual stirring can be achieved by manually rotating the stirring rod 14. A driven gear 5 is slidably arranged on the top of the stirring rod 14 of the device, and the driven gear 5 is meshed with the driving gear 13 to achieve automatic high-frequency stirring of the stirring rod 14 driven by the electric motor 12. In order to facilitate the mutual conversion between the two, a limiting groove 7 is provided on the driven gear 5, and a limiting block 15 is provided on the top of the stirring rod 14, and the limiting block 15 is embedded in the limiting groove 7. In this way, when the limiting block 15 is inserted into the limiting groove 7, the driven gear 5 and the driving gear 13 are meshed to realize automatic stirring, otherwise manual stirring can be achieved.

[0021] In another embodiment, in order to facilitate the connection and use of the stirring rod 14, a rectangular sliding hole 8 for the limit block 15 to pass through is provided at the center of the cylinder cover 2; a rectangular sliding hole 8 for the limit block 15 to pass through is also provided on the driven gear 5, and the depth of the limit groove 7 is half the thickness of the driven gear 5. The limit groove 7, the rectangular sliding hole 8 and the limit block 15 are symmetrically arranged in two, and the limit groove 7 and the rectangular sliding hole 8 are arranged perpendicular to each other.

[0022] In the present device, the barrel 1 is used as a stirring container for a chemical room, and the barrel cover 2 can be fixed to the top of the barrel 1 by means of a threaded connection. When stirring is required, one way is to pull out the stirring rod 14 and directly put it into the barrel 1 for manual stirring, which is convenient for use. At the same time, the stirring rod 14 can also be inserted into the insertion hole 6 and inserted from the bottom of the barrel cover 2, and the limit block 15 is aligned with the rectangular slide hole 8. After the limit block 15 passes through the rectangular slide hole 8, the stirring rod 14 is rotated so that the limit block 15 is aligned with the limit groove 7 and falls, so that the limit block 15 is embedded in the The two limit grooves 7 are stuck, the two limit grooves 7 and the rectangular sliding hole 8 are distributed around the insertion hole 6 and are all connected to the insertion hole 6. The limit grooves 7 do not pass through the rotating shaft 4, and the rectangular sliding hole 8 passes through the rotating shaft 4 and the cylinder cover 2, which is convenient for the disassembly and installation of the stirring rod 14. After the limit block 15 is embedded in the limit groove 7, the rotating shaft 4 is electrically driven to rotate, so that the rotating shaft 4 can drive the stirring rod 14 to rotate, and automatic stirring can be performed in the cylinder 1. The device can switch between automatic and manual according to actual needs. It not only has high stirring efficiency, but also is convenient and practical.

[0023] In another embodiment, Figure 4 In order to ensure that the stirring rod 14 is separated from the driven gear 5, a boss is provided in the center of the driven gear 5, on which a fixing cover 9 is connected. The boss can be simply cylindrical and have threads provided thereon, on which the fixing cover 9 is screwed. Of course, it can also be other shapes and fastening structures, such as a square snap-on connection result; the jack 6, the limit groove 7, and the rectangular slide hole 8 are set through the fixing cover 9.

[0024] In another embodiment, a plurality of evenly distributed stirring blades 16 are fixed to the lower portion of the circumferential surface of the stirring rod 14 to facilitate stirring.

[0025] In another embodiment, a handle 10 is fixed on the circumferential surface of the cylinder cover 2, and a base 3 is fixed on the bottom of the cylinder body 1. The handle 10 facilitates the removal and installation of the cylinder cover 2, and the base 3 can support the cylinder body 1 on the desktop, so that the cylinder body 1 is more stable when placed.

[0026] When the device is used, if manual stirring is required, the stirring rod 14 can be used to stir directly in the barrel 1, and even the driven gear 5 can be directly separated from the driving gear 13 and the driven gear 5 can be directly rotated manually to achieve manual stirring. If automatic stirring is required, the stirring rod 14 can be inserted into the insertion hole 6 from the bottom of the barrel cover 2, and the limit block 15 is aligned with the rectangular slide hole 8. After the limit block 15 passes through the rectangular slide hole 8, the stirring rod 14 is rotated so that the limit block 15 is aligned with the limit groove 7 and falls, so that the limit block 15 is embedded in the two limit grooves 7 and stuck, and then the fixed cover 9 is threadedly connected to the top of the rotating shaft 4. At this time, the electric motor 12 is started, and the output end of the electric motor 12 drives the driving gear 13 to rotate, and the driving gear 13 drives the rotating shaft 4 and the driven gear 5 to rotate together through the meshing with the driven gear 5, so that the rotating shaft 4 can drive the stirring rod 14 to rotate at the same time, and finally can drive the stirring rod 14 to stir automatically. The device can switch between automatic and manual according to actual needs, which is not only efficient in stirring, but also convenient and practical.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
