Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, specifically to a mixing cover. Background Technology

[0002] In the current field of catering automation and beverage preparation, in order to ensure the uniformity of taste and quality of beverages containing fruit pulp, concentrated pulp or easily sedimented materials (such as mango puree and mandarin orange juice) at the time of production, it is usually necessary to install a stirring device in the storage container.

[0003] Stirring devices can generally be divided into consumer-grade self-stirring containers and integrated stirring systems in commercial beverage dispensers. Consumer-grade self-stirring containers typically integrate a small DC motor and battery compartment into the bottom or handle of the container, with stirring performed by a magnetic stir bar located at the bottom or a fixed small impeller. Integrated stirring systems in commercial beverage dispensers function as a fixed component of a large beverage storage tank (typically a few liters to tens of liters in capacity). The stirring motor is usually mounted externally (below or behind) of the tank, driving a large stirring paddle or plate inside via a drive shaft passing through a sealed structure. Both methods achieve the stirring function; however, these technologies generally lack modularity and operational flexibility. Users cannot selectively use or remove the stirring function from the same container according to actual needs. This means that for materials that do not require stirring (such as syrup or pure tea), either an expensive container with stirring function is used, resulting in resource waste, or two different containers are needed—one with stirring and one without—significantly increasing equipment procurement costs and storage space requirements.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, a stirring cover is provided, comprising: a cover body 1 and a stirring assembly 2. The stirring assembly 2 includes a stirring shell 21, a motor 22 and a stirring shaft 23. The stirring shell 21 is detachably connected to the cover body 1. The stirring shell 21 and the cover body 1 form a sealing cavity 3. The motor 22 is disposed in the sealing cavity 3. The stirring shaft 23 is connected to the motor 22. At least one stirring structure 24 is provided on the stirring shaft 23.

[0031] Specifically, the stirring cover is used on the stirring device to seal the stirring chamber and simultaneously stir the material inside. The stirring assembly 2 is located on the side of the cover 1 facing the stirring chamber, and the cover 1 covers the top of the stirring chamber so that the stirring shaft 23 and the stirring structure 24 extend into the stirring chamber. The stirring shell 21 is detachably connected to the cover 1, and a sealing cavity 3 is constructed between the stirring shell 21 and the cover 1. The motor 22 is located in the sealing cavity 3, and the output shaft of the motor 22 is connected to the stirring shaft 23 to drive the stirring shaft 23 to rotate, so that the stirring shaft 23 drives the stirring structure 24 to rotate for stirring. Three stirring structures 24 are provided on the stirring shaft 23, so that the material can be fully stirred. The three stirring structures 24 are located at the upper, middle and lower parts of the stirring shaft 23, respectively, forming upper, middle and lower stirring layers when stirring the material. Preferably, the main body of the cover 1 is injection molded from polyphenylene ether plastic material. This material has sufficient mechanical strength to support the stirring component 2 and a certain degree of flexibility to better seal with the stirring chamber and absorb the small vibrations generated during stirring.

[0032] The mixing housing 21 is detachably connected to the cover 1, allowing users to easily install or remove the mixing assembly 2 according to actual needs, achieving modularity and operational flexibility in the mixing function. When mixing is required, the mixing assembly 2 is installed on the cover 1; when mixing is not required, the mixing assembly 2 is removed, and the mixing cover can be used as a regular cover, greatly saving equipment procurement costs and storage space. Furthermore, the design of the sealing cavity 3 effectively prevents liquid leakage that may occur during motor 22 operation, improving the safety and reliability of the equipment.

[0033] In one embodiment, the stirring shell 21 is provided with snap-fit ​​members 25 on both sides, and the cover 1 is provided with snap-fit ​​part 11. The stirring shell 21 is snapped into the cover 1 through the snap-fit ​​members 25 and the snap-fit ​​part 11.

[0034] Specifically, such as Figure 3As shown, the snap-fit ​​component 25 is a protruding structure provided on both sides of the stirring shell 21, and the snap-fit ​​part 11 is a groove structure provided on the cover 1 that matches the protruding structure. When it is necessary to connect the stirring shell 21 and the cover 1, simply align the protruding structure on both sides of the stirring shell 21 with the groove structure on the cover 1, and then press it firmly so that the protruding structure snaps into the groove structure, thereby realizing the snap-fit ​​connection between the stirring shell 21 and the cover 1. This snap-fit ​​method is simple and convenient, easy for users to operate, and the connection is firm, which can ensure the stability of the stirring component 2 during the stirring process.

[0035] The engagement between the stirring housing 21 and the cover 1 is achieved through the cooperation of the snap-fit ​​part 25 and the snap-fit ​​part 11. Compared with traditional bolt connections, no additional tools are required, which greatly improves the efficiency of installation and disassembly and further enhances the modularity and operational flexibility of the stirring function.

[0036] In one embodiment, a wireless power supply component 4 is provided inside the sealed cavity 3, and the wireless power supply component 4 is connected to the motor 22.

[0037] Specifically, the use of wireless power supply avoids complex wiring connections inside the sealed cavity 3, reduces safety hazards caused by aging or damage of wires, and improves the sealing performance of the sealed cavity 3, further ensuring the safety and reliability of the equipment.

[0038] In one embodiment, the wireless power supply component 4 includes an electromagnetic transmitter, an electromagnetic receiver coil 41, and an electromagnetic receiver circuit board 42 disposed on the stirring device. The electromagnetic receiver coil 41 and the electromagnetic receiver circuit board 42 are connected, and the electromagnetic receiver circuit board 42 is connected to the motor 22.

[0039] Specifically, such as Figure 2 As shown, when the stirring cover is placed in the designated position of the stirring equipment, the electromagnetic transmitter inside the stirring equipment is aligned with the electromagnetic receiver coil 41 in the sealed cavity 3. The electromagnetic transmitter generates a high-frequency alternating magnetic field, which penetrates the cover 1 and the stirring shell 21, inducing a current in the electromagnetic receiver coil 41. After rectification, filtering and voltage stabilization by the electromagnetic receiver circuit board 42, the current outputs a stable and reliable DC power to supply the motor 22. This non-contact energy transmission method is similar to the widely used Qi wireless charging standard. Its key advantage is that the stirring component 2 can be made into a fully sealed whole without any external power interface, fundamentally eliminating the leakage and waterproof failure problems caused by physical joints.

[0040] The wireless power supply design not only simplifies the structure of the mixing lid but also greatly enhances its safety and convenience. Users do not need to worry about equipment malfunctions or safety hazards caused by tangled wires, loose connections, or liquid leakage. Simply place the mixing lid correctly on the mixing equipment, and it will automatically start wireless power supply and drive the motor 22. In addition, the fully sealed mixing component 2 design facilitates cleaning and maintenance, effectively extending the service life of the equipment and reducing long-term operating costs.

[0041] In one embodiment, the outer surface of the motor 22 is covered with a waterproof sleeve 5, and the connection between the motor 22 and the stirring structure 24 has an oil seal structure.

[0042] Specifically, the waterproof sleeve 5 is made of a material with good waterproof performance, such as rubber or silicone, and tightly wraps around the outer surface of the motor 22, effectively preventing liquid from entering the motor 22 and protecting it from liquid corrosion. An oil seal structure (not shown) is located at the connection between the output shaft of the motor 22 and the quick-release structure 6. The oil seal structure is a rotating shaft lip seal ring, which maintains a tight fit to the shaft even when the output shaft of the motor 22 rotates at high speed, forming a reliable dynamic waterproof barrier. Even in the extreme case of brief immersion of the motor 22, this oil seal structure can effectively prevent liquid from seeping into the motor 22 along the output shaft.

[0043] The waterproof sleeve 5 and the oil seal structure provide effective sealing protection for both the exterior of the motor 22 and the connection parts, greatly improving the working stability of the motor 22 in humid environments and extending the service life of the motor 22.

[0044] In one embodiment, the output shaft of the motor 22 is located outside the sealed cavity 3, and the output shaft of the motor 22 is detachably connected to the stirring shaft 23 through the quick-release structure 6. The oil seal structure is located at the connection between the output shaft of the motor 22 and the quick-release structure 6.

[0045] Specifically, such as Figures 1 to 3As shown, the stirring shaft 23 is quickly installed and disassembled from the output shaft of the motor 22 via the quick-release structure 6. This quick-release structure 6 allows users to replace or repair the stirring shaft 23 without opening the sealing cavity 3, avoiding the risk of decreased sealing performance or damage to the motor 22 due to improper operation. Specifically, when disassembling the stirring shaft 23, the user only needs to operate the unlocking component on the quick-release structure 6 to separate the stirring shaft 23 from the output shaft of the motor 22. The entire process is simple and quick, requiring no tools. Similarly, when installing the stirring shaft 23, the user only needs to align the stirring shaft 23 with the connection point on the quick-release structure 6 and apply a certain amount of pressure to securely connect the stirring shaft 23 to the output shaft of the motor 22. The quick-release structure 6 not only improves the maintenance efficiency of the stirring cover but also reduces maintenance costs, further enhancing the practicality and economy of the stirring cover.

[0046] In one embodiment, the quick-release structure 6 includes a quick connector 61 disposed on the output shaft and a connector 62 disposed on the stirring shaft 23 and engaging with the quick connector 61.

[0047] Specifically, such as Figure 1 and Figure 3 As shown, when it is necessary to connect the stirring shaft 23 to the output shaft of the motor 22, simply align the connector 62 on the stirring shaft 23 with the quick connector 61 on the output shaft of the motor 22, and then gently push the stirring shaft 23 so that the connector 62 snaps into the quick connector 61, thus achieving a quick connection between the stirring shaft 23 and the output shaft of the motor 22. When disassembly is required, simply pull the stirring shaft 23 forcefully to disengage the connector 62 from the quick connector 61, thus completing the disassembly. The quick-release structure 6 makes the connection and disassembly of the stirring shaft 23 and the output shaft of the motor 22 more convenient and quick, further improving the modularity and operational flexibility of the stirring function. Users can quickly replace the stirring shaft 23 or perform other maintenance operations according to actual needs.

[0048] In one embodiment, quick connector 61 is any one of spline, square interface, or ball joint.

[0049] Specifically, if the quick connector 61 adopts a spline structure, the spline has multiple teeth, providing a larger connection area and better alignment, making the connection between the stirring shaft 23 and the output shaft of the motor 22 more stable and able to withstand greater torque. If a square interface is adopted, its structure is simple and easy to manufacture; during connection, simply align and insert the square interface, ensuring the coaxiality of the stirring shaft 23 and the output shaft of the motor 22. When a ball-loaded snap-fit ​​structure is adopted, a ball and a spring are provided inside the quick connector 61, and a corresponding slot is provided on the connector 62. When the connector 62 is inserted into the quick connector 61, the ball is snapped into the slot under the action of the spring, achieving quick connection. During disassembly, simply press the ball to disengage it from the slot, and the connector 62 can be pulled out. Different forms of quick connectors 61 provide users with more choices. Users can choose the most suitable form of quick connector 61 according to actual usage scenarios and needs to meet different stirring requirements.

[0050] In one embodiment, three stirring structures 24 are provided on the stirring shaft 23, and the stirring structures 24 are movably connected to the stirring shaft 23 so that the stirring structures 24 can move relative to each other along the guiding direction of the stirring shaft 23.

[0051] Specifically, the stirring structure 24 is slidably mounted on the stirring shaft 23 and can move along the guide direction of the stirring shaft 23. After the stirring structure 24 moves to the designated position, a limiting component can be used to fix the stirring structure 24 on the stirring shaft 23. The limiting component can be a common mechanical limiting element such as a locking nut or a positioning pin. When the stirring structure 24 slides to the preset position, the locking nut is rotated to make it threadedly engage with the stirring shaft 23 to form axial compression, or the positioning pin is inserted through the positioning hole between the stirring structure 24 and the stirring shaft 23 to achieve circumferential fixation. The user can flexibly adjust the position of the three stirring structures 24 on the stirring shaft 23 according to the characteristics of the material being stirred, such as viscosity and particle size. For example, when stirring a material with high viscosity, the three stirring structures 24 can be relatively close together and concentrated in the middle area of ​​the stirring shaft 23 to enhance the stirring force and allow the material to be mixed more thoroughly; while when stirring a material with low viscosity and good fluidity, the three stirring structures 24 can be dispersed and located at the upper, middle, and lower parts of the stirring shaft 23 respectively to expand the stirring range and improve the stirring efficiency. This movable stirring structure 24 greatly enhances the adaptability of the stirring cover to different materials, further improving the stirring effect. At the same time, the setting of the limiting component ensures the stability of the stirring structure 24 during the stirring process, preventing displacement due to material resistance, and guaranteeing the uniformity and reliability of the stirring.

[0052] In one embodiment, the stirring structure 24 includes three stirring blades 241.

[0053] Specifically, the three stirring blades 241 can provide a more thorough stirring action. During the stirring process, the three blades can form a wider stirring zone, ensuring that the material is uniformly mixed in the stirring chamber. The three blades can more effectively break up the agglomeration structure in the material, promote the flow and mixing of the material, thereby improving the stirring efficiency and quality.

[0054] In other alternative embodiments, the stirring structure 24 may include two or four or other numbers of stirring blades 241.
