[0017] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0018] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0019] The milk mixer provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0020] Example 1: The embodiment of the present application provides a milk mixer with an improved hinge structure 5 of an opening and closing cover 4, comprising an outer shell 1, a drying shell 2 and a sterilizing shell 3, and an opening and closing cover 4, which is foldably mounted on the top of the sterilizing shell 3 through the hinge structure 5, and the hinge structure 5 includes a base 51 mounted on the outer wall of the sterilizing shell 3, and a pair of connecting rods 53 are rotatably mounted on the base 51 through a hinge shaft 52. A pair of notches 54 are provided on the side wall of the sterilizing shell 3, and each connecting rod 53 is movably arranged in the notch 54 and is fixedly connected to one end of the bottom surface of the opening and closing cover 4 away from the end of the hinge shaft 52. A mounting groove 55 is also provided on the base 51, and a damping assembly 6 and a retaining assembly 7 for cooperating with the hinge shaft 52 are provided in the mounting groove 55. The damping assembly 6 is used to provide damping force for the rotation of the hinge shaft 52, and the retaining assembly 7 is used to lock the hinge shaft 52 after the opening and closing cover 4 is opened.

[0021] In this embodiment of the present application, the damping assembly 6 includes a damping block 61 that is slidably installed at one end of the mounting groove 55. One end of the twisted shaft 52 is conical and extends into the mounting groove 55. One end of the damping block 61 is provided with a conical groove that is adapted to the end of the twisted shaft 52, and a spring 62 is provided between the other end and the inner wall of the mounting groove 55.

[0022] In this embodiment of the present application, knurling is provided on the peripheral wall of the conical end of the twist shaft 52 .

[0023] like Figures 1 to 5 As shown, due to the adoption of the above structure, when the opening and closing cover 44 is opened and closed, the hinge shaft 52 rotates synchronously with the connecting rod 53, and its tapered end rotates in the mounting groove 55 and squeezes the damping block 61. The spring 1 62 always applies a thrust toward the tapered end of the hinge shaft 52 to the damping block 61, so that the tapered groove of the damping block 61 fits tightly with the tapered end of the hinge shaft 52. The knurling of the peripheral wall of the tapered end of the hinge shaft 52 increases the friction coefficient of the contact surface with the damping block 61. When the hinge shaft 52 rotates, the damping block 61 slides due to the friction force. The cover plate 51 is in a state of being moved in a downward direction, but is limited by the guide structure of the mounting groove 55 and can only slide slightly along the axis of the hinge shaft 52. At this time, the elastic force of the spring 1 62 is converted into a damping force that hinders the rotation of the hinge shaft 52, so that the cover plate is subjected to continuous resistance during the opening and closing process, thereby avoiding rapid opening and closing due to gravity or external force. When the cover plate stops moving, the damping block 61 maintains close contact with the tapered end of the hinge shaft 52 under the action of the spring 1 62, forming a static friction force, thereby preventing the cover plate from rotating on its own due to slight shaking, thereby achieving a smooth and controllable opening and closing process.

[0024] The knurling is a straight knurling with a tooth pitch of 0.5-1.0 mm and a depth of 0.2-0.3 mm.

[0025] Example 2: In this embodiment, in addition to the structural features of the aforementioned embodiments, the retaining assembly 7 includes a hook 71 fixed on the peripheral wall of the twist shaft 52, and a floating pressing member 72 is installed at one end of the mounting groove 55. The upper end of the floating pressing member 72 extends out of the outer shell 11, and the lower end is floatingly mounted with a clamping plate 74 through a reset member 73. The clamping plate 74 is provided with a clamping groove 75 for the hook 71 to engage.

[0026] In this embodiment of the present application, the floating pressing member 72 includes a mounting shell 721 fixed on the top of the outer shell 11 and extending into the mounting groove 55. A pressing block 723 is floatingly installed in the mounting shell 721 through a spring 2 722. A connecting rod 53 is fixed to the lower end of the pressing block 723. The lower end of the connecting rod 53 passes through the bottom of the mounting shell 721 and extends into the mounting groove 55. The clamping plate 74 is installed at the lower end of the connecting rod 53.

[0027] In this embodiment of the present application, the reset member 73 includes a bolt 731, which slides through the clamping plate 74 and is connected to the bottom of the floating pressing member 72 through a screw hole. A spring 732 is installed between the lower end of the bolt 731 and the bottom surface of the clamping plate 74.

[0028] like Figures 2 to 5 As shown, due to the adoption of the above-mentioned structure, when the opening and closing cover 44 is opened, the hook 71 on the peripheral wall of the hinge shaft 52 first pushes the card plate 74 to slide down along the bolt 731, and the spring three 732 and the spring two 722 are compressed and shortened. When the opening and closing cover 44 is opened to a preset angle, the slot 75 is aligned with the hook 71, and the spring three 732 and the spring two 722 release elastic potential energy to push the card plate 74 up, so that the slot 75 and the hook 71 are precisely engaged, thereby locking the rotational freedom of the hinge shaft 52 and preventing the cover from accidentally closing due to external force.

[0029] When it is necessary to close the cover, the pressing block 723 at the upper end of the floating pressing member 72 is pressed, and the pressing block 723 overcomes the elastic force of the second spring 722 and moves downward, driving the card plate 74 to move downward through the connecting rod 53, and the card slot 75 disengages from the hook 71, releasing the locked state, closing the opening and closing cover 44 to make the hook 71 away from the card slot 75, releasing the pressing block 723, and the second spring 722 pushes the pressing block 723, the connecting rod 53 and the card plate 74 to rise, so that the retaining assembly 7 returns to its initial state and prepares for the next locking. This structure realizes reliable locking and convenient unlocking after the cover is opened through mechanical linkage, thereby improving operational safety.

[0030] The engagement angle between the hook 71 and the slot 75 is 90°, that is, the locking is triggered when the opening and closing cover 4 is opened to 90° with the top of the sterilization shell 3. This angle can be adjusted according to ergonomic requirements.

[0031] Example 3: In this embodiment, in addition to the structural features of the aforementioned embodiments, a magnet 1 8 is fixedly provided at one end of the opening and closing cover 44 away from the hinge structure 5 , and a magnet 2 9 corresponding to the magnet 1 8 is fixedly provided on the top inner wall of the housing 11 .

[0032] like Figure 2As shown, in this embodiment of the present application, due to the adoption of the above-mentioned structure, when the opening and closing cover 44 is closed, the magnet 1 8 at the cover end away from the hinge end and the magnet 2 9 on the inner wall of the shell 11 generate a magnetic attraction due to the opposite poles. The magnetic force and the damping force of the hinge structure 5 work together to ensure that the cover is tightly fitted on the top of the sterilization shell 33. The magnetic attraction force is directional and is only triggered when the cover is fully closed. The magnitude of the attraction force matches the magnetic strength of the magnet, which ensures the sealing effect without causing excessive resistance to the opening operation. When the cover needs to be opened, the external force applied by the user overcomes the magnetic attraction and damping force, causing the opening and closing cover 44 to rotate around the hinge shaft 52, and the magnet 1 8 separates from the magnet 2 9, achieving easy opening. This design improves the airtightness of the sterilization shell 33 during the sterilization process through magnetic auxiliary sealing, preventing water vapor from leaking or external pollutants from entering.

[0033] Example 4: In this embodiment, in addition to the structural features of the previous embodiments, the connecting rod 53 is U-shaped.

[0034] like Figure 4 As shown, in this embodiment of the present application, due to the adoption of the above-mentioned structure, the two ends of the U-shaped connecting rod 53 are respectively fixed to the hinge shaft 52 and the opening and closing cover 44, and its opening direction is toward the outside of the sterilization shell 33, forming a hollow support structure.

[0035] On the one hand, this design enhances the bending strength of the connecting rod 53 through its U-shaped geometric shape, making it less likely to deform during frequent opening and closing, thereby ensuring the stability of the hinge structure 5. The U-shaped arm of the connecting rod 53 is vertically connected to the hinge shaft 52, ensuring uniform force transmission during rotation, so that the cover is subjected to balanced force when opening and closing, and combined with the damping force of the damping component 6, further improving the smoothness of the opening and closing action.

[0036] Example 5: like Figure 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, a light board 10 is installed on the outer wall of the sterilization shell 33, an ultraviolet germicidal lamp 11 is installed on the light board 10, and a light-transmitting hole 12 corresponding to the position of the ultraviolet germicidal lamp 11 is opened on the side wall of the sterilization shell 33.

[0037] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the ultraviolet sterilization lamp 11 is fixed on the lamp board 10, the lamp board 10 is installed on the outer wall of the sterilization shell 33, and the light-transmitting hole 12 is aligned with the position of the lamp bead. When the milk mixer starts the sterilization function, the ultraviolet sterilization lamp 11 is powered on and emits light. Ultraviolet rays with a wavelength of 200-280nm are shot into the inner cavity of the sterilization shell 33 through the light-transmitting hole 12, destroying the DNA or RNA structure of microorganisms such as bacteria and viruses, causing them to lose their reproductive ability, thereby achieving a sterilization effect. The position of the light-transmitting hole 12 precisely corresponds to the lamp board 10, ensuring that the ultraviolet energy is concentratedly projected into the interior of the sterilization shell 33 to avoid energy scattering. At the same time, the inner wall of the sterilization shell 33 can be designed to be a reflective material to enhance the diffuse reflection of ultraviolet rays and cover more sterilization areas. This structure places the ultraviolet light source externally, avoids direct contact between the light source and the liquid or utensils in the sterilization shell 33, improves safety and light source life, and the sealing design of the light-transmitting hole 12 also prevents water vapor from eroding the lamp board 10.

[0038] Example 6: like Figure 4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, a convex ring 13 adapted to the inner cavity of the sterilization shell 33 is fixedly provided on the bottom surface of the opening and closing cover 44 .

[0039] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the shape of the convex ring 13 is adapted to the contour of the top of the inner cavity of the sterilization shell 33. When the opening and closing cover 44 is closed, the convex ring 13 is embedded in the inner wall of the sterilization shell 33 to form a physical sealing structure. The convex ring 13 is made of elastic material (such as silicone) and has a certain compression deformation ability. When the cover is closed, it fits tightly with the inner wall of the sterilization shell 33, and cooperates with the magnetic attraction of magnet 1 8 and magnet 2 9 to further improve the sealing performance. The convex ring 13 can prevent external dust and impurities from entering the sterilization shell 33, avoiding secondary contamination. In addition, the setting of the convex ring 13 gives the cover a clear sense of positioning when it is closed. The user can judge whether the cover is completely closed by touch or hearing, which improves the intuitiveness of the operating experience.
