DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] In the description of the present invention, it should be noted that, for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like, indicating directions and positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present invention.

[0029] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0030] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0031] A base 1, used for a milk mixer, such as Figure 1 and Figure 2As shown, the apparatus comprises a main unit 10, a base 20, and a water outlet arm 30. The main unit 10 is provided with a water outlet pipe adapted to communicate with the water bottle 2 of the milk mixer. The base 20 is connected to one side of the main unit 10 and is used to receive and heat the water bottle 2. The water outlet arm 30 is connected to the main unit 10 and extends outward toward the other side of the main unit 10. The water outlet arm 30 has a connecting end 31 and a free end 32 disposed opposite each other. The connecting end 31 is rotatably connected to the main unit 10, allowing the water outlet arm 30 to switch between a water outlet position and a stowage position. The free end 32 has a water outlet 351, which is connected to the water outlet pipe to allow liquid to flow out of the water outlet 351. When the water outlet arm 30 is in the water outlet position, the water outlet 351 is vertically aligned with the bottle placement area. When the water outlet arm 30 is in the stowage position, the water outlet 351 is vertically offset from the placement area.

[0032] It is understood that when the water outlet arm 30 is in the avoidance position, the water outlet 351 is offset from the placement area, which helps reduce the risk of the water outlet arm 30 colliding with the feeding bottle and reduces the interference of the water outlet arm 30 with the movement path of the feeding bottle, making it easier for the user to place the feeding bottle in the placement area. Furthermore, when the water outlet arm 30 is in the water outlet position, the water outlet 351 and the placement area are arranged in a vertical direction relative to each other, which is suitable for aligning the water outlet 351 with the bottle mouth, thereby facilitating water filling into the feeding bottle, thereby improving the convenience of using the milk mixer and improving the efficiency of preparing milk powder.

[0033] In a specific embodiment, the base 1 also includes a placement table, which protrudes from one side of the lower end of the main unit 10. When the water outlet arm 30 is in the water outlet position, the water outlet 351 and the placement table are arranged opposite to each other in the vertical direction. The size of the top surface 12 of the placement table is slightly larger than the size of the bottom surface of the bottle to form a placement area. When the bottle is placed in the placement area, the bottle mouth of the bottle can be arranged opposite to the water outlet 351 of the water outlet arm 30 in the vertical direction.

[0034] In another specific embodiment, the base 1 also includes an extension platform, which protrudes from one side of the lower end of the main unit 10. The extension platform is provided with a placement groove suitable for accommodating a baby bottle. The placement groove defines a placement area. When the water outlet arm 30 is in the water outlet position, the water outlet 351 is arranged opposite to the placement groove in the vertical direction. Then, when the baby bottle is placed in the placement groove, the bottle mouth of the baby bottle can be arranged opposite to the water outlet 351 of the water outlet arm 30 in the vertical direction.

[0035] In some embodiments, as Figure 7-Figure 9As shown, the base 1 also includes a milk-shaking assembly 40 for rotating a milk bottle. The milk-shaking assembly 40 is connected to the main unit 10 and has a receiving cavity 4211 for placing the milk bottle. The receiving cavity 4211 defines a placement area. When the water outlet arm 30 is in the water outlet position, the water outlet 351 of the water outlet arm 30 is vertically arranged relative to the receiving cavity 4211, thereby allowing the bottle mouth of the milk bottle to be arranged relative to the water outlet 351, so that the water outlet arm 30 can inject warm water into the milk bottle through the water outlet 351. When the water outlet arm 30 is in the avoidance position, the vertical projection of the water outlet 351 is offset from the receiving cavity 4211, which helps to prevent the upper part of the receiving cavity 4211 from being blocked, thereby facilitating the user to vertically place the milk bottle into or remove it from the receiving cavity 4211, thereby improving the ease of operation.

[0036] It can be understood that warm water can be injected into the bottle through the water outlet 351 on the water outlet arm 30. Furthermore, the milk shaking component 40 can realize the function of automatic milk shaking, so as to make the milk powder brewing more convenient, save manpower and time, and improve the efficiency of milk powder brewing.

[0037] It is worth mentioning that if the water outlet 351 is fixedly located above the accommodating chamber 4211, the distance between the water outlet 351 and the opening of the accommodating chamber 4211 needs to be greater than the height of the milk bottle, so that the milk bottle can be first moved between the water outlet 351 and the accommodating chamber 4211 and then lowered into the accommodating chamber 4211, which is relatively inconvenient. In this embodiment, the milk bottle can be vertically inserted into the accommodating chamber 4211 by simply rotating the water outlet arm 30 to the avoidance position, which is simple to operate. Moreover, the distance between the water outlet 351 and the opening of the accommodating chamber 4211 does not need to be greater than the height of the milk bottle, which helps to shorten the distance between the water outlet 351 and the opening of the accommodating chamber 4211, making the structure of the base 1 more compact, and thus helping to reduce the overall height of the milk mixer.

[0038] In some embodiments, as Figure 3-Figure 6 As shown, the main unit 10 has a limiting wall 11, which is arranged opposite the outer wall of the connecting end 31 and has at least two limiting grooves 111 spaced apart along the rotation direction of the connecting end 31. The water outlet arm 30 has a locking member 33, at least a portion of which protrudes from the outer wall of the connecting end 31, and the distal end of the locking member 33 is adapted to engage with the limiting groove 111 to maintain the water outlet arm 30 in the water outlet position or the avoidance position. It is understood that the limiting wall 11 can be located on the horizontal wall surface of the main unit 10 or on the vertical wall surface of the main unit 10, and this application does not impose specific limitations on this.

[0039] That is, when the water spout arm 30 is in the water spout position, the locking member 33 on the water spout arm 30 engages with at least one limiting groove 111 on the limiting wall 11, thereby maintaining the water spout arm 30 in the water spout position. This reduces the risk of accidental rotation of the water spout arm 30 during the water spout process, thereby preventing water from falling outside the feeding bottle and scalding the user, thereby improving the safety of the milk mixer. Furthermore, when the water spout arm 30 is in the avoidance position, the locking member 33 on the water spout arm 30 engages with at least one other limiting groove 111 on the limiting wall 11, thereby maintaining the water spout arm 30 in the avoidance position. This reduces the risk of the user being struck by the rotating water spout arm 30 when placing or removing a feeding bottle, thereby improving the safety of the milk mixer.

[0040] It is worth mentioning that the avoidance position can be located only on one side of the water outlet position. That is, there is at least one avoidance position on one side of the water outlet position, and the water outlet arm 30 can only rotate from the water outlet position to one side to reach the avoidance position. This facilitates the placement of the control panel 121 on the other side of the water outlet position, which helps prevent the water outlet arm 30 from rotating and interfering with the control panel 121. The avoidance position can also be located on both sides of the water outlet position. That is, there is at least one avoidance position on each side of the water outlet position, and the water outlet arm 30 can rotate to either side to reach the avoidance position, which helps improve the operational flexibility of the water outlet arm 30. This application does not impose specific limitations on this.

[0041] In a specific embodiment, Figure 3 and Figure 4 As shown, the locking member 33 is a protrusion 331, which is protruding from the side wall of the water outlet arm 30 opposite the limiting wall 11. The distal end of the protrusion 331 is adapted to fit within the limiting groove 111. During the rotation of the water outlet arm 30, the protrusion 331 abuts against the limiting wall 11. At this time, a gap exists between the side wall of the connecting end 31 of the water outlet arm 30 and the limiting wall 11 of the main unit 10, allowing the connecting end 31 of the water outlet arm 30 to rotate relative to the main unit 10. It is worth mentioning that the protrusion 331 can be integrally formed with the outer shell of the water outlet arm 30, thereby reducing the number of parts in the base 1 and thus reducing costs.

[0042] In another specific embodiment, Figure 5 and Figure 6 As shown, the locking member 33 is a ball plunger 332, which is mounted on the side wall of the water outlet arm 30 opposite the limiting wall 11. The positioning bead of the ball plunger 332 is adapted to fit within the limiting groove 111. It is worth mentioning that the ball plunger 332 is a standard part, which is easy to purchase and install, and has a low cost.

[0043] It is understandable that the water outlet arm 30 can be rotated manually by the user, thereby reducing the installation of components such as motors, which is conducive to making the structure of the base 1 simpler and lower in cost; the water outlet arm 30 can also be driven by a motor, which is conducive to improving the convenience of operation. This application does not impose any specific restrictions on this.

[0044] In some embodiments, as Figure 1 As shown, the water dispensing arm 30 includes a main body 34 and an extension 35. One end of the main body 34 is connected to the top surface 12 of the main unit 10, and the other end of the main body 34 is vertically opposed to the milk-shaking assembly 40. The main body 34 is higher than the top surface 12 of the main unit 10, which helps prevent interference between the main body 34 and the main unit 10 during rotation. The extension 35 extends from the end of the main body 34 toward the milk-shaking assembly 40 and has a water outlet 351 at the end of the extension 35. This minimizes the distance between the water outlet 351 and the bottle mouth, reducing the risk of water splashing out of the bottle and improving operational safety.

[0045] In some embodiments, as Figure 2 As shown, the angle α between the water outlet position and the avoidance position of the water outlet arm 30 is 35°≤α≤90°, thereby avoiding the placement area and making the vertical projection of the water outlet arm 30 deviate from the placement area, thereby facilitating the user to vertically place the bottle in the accommodating cavity 4211. Preferably, 45°≤α≤80°.

[0046] In some embodiments, as Figure 7-Figure 9 As shown, the milk shaking assembly 40 includes a base 41, a rotating drum assembly 42 and a driving assembly 43. The base 41 is connected to the main unit 10 and is located below the water outlet 351. The rotating drum assembly 42 and the driving assembly 43 are both arranged on the base 41. The rotating drum assembly 42 has a accommodating cavity 4211, and the driving assembly 43 is suitable for driving the rotating drum assembly 42 to rotate.

[0047] It is understood that when a feeding bottle is placed in the accommodating chamber 4211 of the rotating drum assembly 42, the accommodating chamber 4211 and the water outlet 351 are arranged vertically opposite each other, thereby enabling the bottle mouth of the feeding bottle to be arranged opposite the water outlet 351, so that the water outlet assembly can inject warm water into the feeding bottle through the water outlet 351. In other words, the accommodating chamber 4211 defines a placement area, which serves to position the feeding bottle, allowing the user to easily align the bottle mouth with the water outlet 351, thereby improving the ease of operation.

[0048] Furthermore, after water filling is complete, the water outlet arm 30 can be rotated to a clear position, thereby preventing the water outlet arm 30 from blocking the upper portion of the feeding bottle and making it easier for the user to tighten the bottle cap. After the bottle cap is tightened, the base 1 can start shaking milk without having to move the feeding bottle, further improving the ease of operation and the efficiency of preparing milk powder.

[0049] In some embodiments, as Figure 7 and Figure 8 As shown, the rotating drum assembly 42 includes an inner cylinder 421, a base 422 and an elastic member 423. The inner cylinder 421 defines a receiving cavity 4211 for placing a feeding bottle; the base 422 is connected to the bottom of the inner cylinder 421 through the elastic member 423. The elastic member 423 is suitable for expanding and contracting along the axial direction of the inner cylinder 421 to drive the base 422 to rise and fall relative to the inner cylinder 421. At least a portion of the base 422 extends from the bottom of the inner cylinder 421 into the receiving cavity 4211 to support the feeding bottle.

[0050] It can be understood that when the bottle is placed in the accommodating cavity 4211 of the inner cylinder 421, the base 422 is against the bottom end of the bottle, and the elastic member 423 drives the base 422 to move up and down along the axial direction of the inner cylinder 421, so that the bottle can be shaken up and down slightly on the basis of following the rotation of the inner cylinder 421 to produce irregular shaking and swinging, which is conducive to alleviating the problem of milk powder being difficult to dissolve and clumping near the center axis of the bottle caused by the conventional single-rotation milk shaking method, thereby improving the efficiency of milk powder dissolution.

[0051] In some embodiments, as Figure 7 and Figure 9 As shown, the rotating drum assembly 42 further includes a clamping ring 424 mounted on the inner drum 421. The clamping ring 424 is used to clamp the feeding bottle, thereby reducing collision between the feeding bottle and the inner drum 421 and preventing the feeding bottle from separating from the inner drum 421 during rotation, bumping, or swinging. In other words, by abutting the waist portion of the feeding bottle with the clamping ring 424, the feeding bottle can achieve centrifugal swing while reducing the risk of collision and damage between the feeding bottle and the inner drum 421, as well as the risk of separation of the feeding bottle from the inner drum 421, thereby improving the safety of the milk shaking assembly 40 during use.

[0052] Specifically, the clamping ring 424 includes a fixing portion 4241 and a deformation portion 4243. A flange 4212 extending radially outward is provided on the top of the inner cylinder 421. The fixing portion 4241 has a groove 4242 adapted to the flange 4212 so that the clamping ring 424 is fixed to the inner cylinder 421. The deformation portion 4243 extends along the axial direction of the inner cylinder 421 and is annularly arranged on the inner circumference side of the inner cylinder 421. At least part of the deformation portion 4243 is suitable for interfering with the bottle to clamp the bottle.

[0053] In some embodiments, as Figure 1 and Figure 2 As shown, the base 1 includes a control panel 121 located on the top surface 12 of the main unit 10. The control panel 121 has several buttons for controlling water flow and / or selecting the water temperature. In other words, through the control panel 121, the user can select the start and stop of water flow, the amount of water flowed, the water temperature, and other settings to improve the efficiency of milk powder preparation. Furthermore, the control panel 121 can also control the position of the water outlet arm 30, further enhancing the automation of the milk mixer and making milk powder preparation more convenient.

[0054] A milk mixer, such as Figure 1 As shown, the milk maker comprises the aforementioned base 1 and kettle 2. The kettle 2 has a chamber 201 for accommodating liquid. When the kettle 2 is placed on the bottom plate 20 of the water outlet assembly of the base 1, the chamber 201 is adapted to communicate with the water outlet 351 of the main body 10 of the water outlet assembly, allowing liquid to flow out of the water outlet 351. It can be understood that the separate arrangement of the kettle 2 and the base 1 makes it easier for the user to remove the kettle 2 to collect water, thereby improving the convenience of using the milk maker.

[0055] The above describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and description merely illustrate the principles of the present invention.
