DETAILED DESCRIPTION

[0030] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0033] Refer to Figures 1 - 5 , the present utility model discloses a liftable heating assembly, including a mounting base 10, a heating mechanism and a linkage mechanism. The heating mechanism includes a heating plate 20 and a heating element 21. The heating plate 20 is installed on the mounting base 10, and the heating plate 20 can move along the height direction of the mounting base 10. The heating element 21 is installed on the heating plate 20. Specifically, the heating element 21 can be structures such as a heating resistor or a heating wire installed at the bottom end of the heating plate 20. Of course, the heating element 21 can also be embedded in the heating plate 20, and its installation position is not limited.

[0034] The above-mentioned linkage mechanism includes a linkage seat 30, a linkage member and an elastic member 43. The linkage seat 30 is rotatably installed on the mounting base 10. A first guiding portion is provided on the linkage seat 30. The linkage member is connected to the heating plate 20. A second guiding portion is correspondingly provided on the linkage member. When the linkage seat 30 rotates, the first guiding portion can be in sliding cooperation with the second guiding portion. When the first guiding portion and the second guiding portion are in sliding cooperation, it can guide the linkage member to move along the height direction of the mounting base 10, and then drive the heating plate 20 connected to the linkage member to move up and down. The above-mentioned elastic member 43 is disposed between the linkage member and the mounting base 10, and the elastic member 43 is used to provide an elastic stress that drives the linkage member to move upward.

[0035] On the basis of the above structure, when using the liftable heating component of the utility model, the liftable heating component can be used in a supplementary food machine, a juicer, a food processor, etc. having a stirring cup 60 structure. By putting the food materials into the stirring cup 60 and then placing the stirring cup 60 into the machine body, the stirring shaft 61 in the stirring cup can be connected to the driving shaft of the driving structure on the machine body 50, so that the driving structure can drive the stirring shaft 61 in the stirring cup 60 to rotate, and then the stirring blade and other structures on the stirring shaft 61 rotate to stir the material in the stirring cup 60.

[0036] Before the blending cup 60 is placed into the machine body 50, the liftable heating component can first be rotated in one direction through the linkage seat 30 of the linkage mechanism. During the rotation of the linkage seat 30, the first guide portion on the linkage seat 30 slides with the second guide portion on the linkage member, so that the linkage member can be guided to move downward, thereby driving the heating plate 20 connected to the linkage member to move downward, and the elastic component 43 is compressed. In this way, the heating plate 20 is in a low position after falling and will not protrude from the bottom of the machine body 50, making it convenient for the blending cup 60 to be placed inside the machine body 50.

[0037] After the mixing cup 60 is placed in the machine body 50, the mixing shaft 61 on the mixing cup 60 can correspond to the driving shaft of the driving structure on the machine body 50, and then, it can be reversely rotated through the linkage seat 30. After the linkage seat 30 is reversely rotated, the elastic component 43 is reset, and the elastic component 43 provided can drive the heating plate 20 connected to the linkage member to move upward. At this time, the first guide part and the second guide part slide together to guide the heating plate 20 to move upward synchronously, and the heating plate 20 can be in a high position after being raised, and the mixing cup 60 is lifted upward. The mixing shaft 61 on the mixing cup 60 can be connected to the driving shaft of the driving structure during the lifting process, and then the driving shaft of the driving structure can drive the mixing shaft 61 in the mixing cup 60 to rotate, thereby realizing the stirring action.

[0038] Of course, the elastic stress provided by the elastic component 43 drives the linkage part to move upward, and the elastic stress provided can also keep the linkage seat 30 in an upward trend, so that the first guide part and the second guide part remain in a fit state, which is convenient for sliding cooperation and guiding downward movement during the next rotation.

[0039] It should also be noted that when the blending cup 60 is heated, the blending cup 60 is placed on the heating plate 20. At this time, the heating plate 20 can slide and cooperate with the second guide portion of the linkage member while the first guide portion of the linkage seat 30 is rotating, guiding the heating plate 20 to rise upward, so that a certain distance can be formed between the heating plate 20 and the mounting base 10. During the heating process of the heating element 21 of the heating plate 20, the mounting base 10 will not be too hot during the heating process of the heating element 21 due to the spacing from the mounting base 10, so the body of the device will not be affected by excessive temperature, which complies with safety regulations.

[0040] The heating plate 20 can be lowered to a lower position again under the linkage effect of the linkage seat 30 and the linkage member. At this time, the stirring shaft 61 of the stirring cup 60 is separated from the driving shaft of the driving structure of the body 50. The stirring cup 60 is taken out without being interfered by the driving shaft, and the stirring cup 60 is easy to take and put.

[0041] Furthermore, the linkage part in this embodiment includes a linkage sleeve 41 and a linkage rod 42. The linkage rod 42 is arranged outside the linkage sleeve 41. The above-mentioned elastic component 43 can be inserted into the linkage sleeve 41 and clamped between the top wall of the linkage sleeve 41 and the bottom wall of the mounting base 10. During assembly, the linkage seat 30 is assembled to the mounting base 10, and then the linkage sleeve 41 is inserted into the linkage seat 30. After the linkage sleeve 41 is inserted into the linkage seat 30, the linkage rod 42 of the linkage sleeve 41 can slide with the first guide portion, so that the linkage rod 42 forms a second guide portion.

[0042] In this way, when the linkage seat 30 rotates, the linkage seat 30 can rotate externally relative to the linkage sleeve 41, and rotate with the linkage sleeve 41 as the rotation center, and the first guide portion can slide with the linkage rod 42, and the linkage rod 42 can slide along the first guide portion during the rotation of the linkage seat 30, thereby guiding the linkage sleeve 41 to move up and down.

[0043] Based on this structure, the heating plate 20 is assembled to the top of the linkage sleeve 41 , and when the linkage rod 42 is guided by the first guide portion to move up and down, the heating plate 20 connected to the linkage sleeve 41 can be driven to move up and down.

[0044] Specifically, a guide track 31 can be provided on the linkage seat 30, and the guide track 31 gradually extends at an angle in the rotation direction of the linkage seat 30. The guide track 31 can be formed as a first guide portion. After the linkage sleeve 41 is connected and assembled to the linkage seat 30, the linkage rod 42 can be located below the guide track 31 and slide with the guide track 31. The elastic stress provided by the elastic component 43 can tend to keep the linkage sleeve 41 downward, and the linkage rod 42 can be pressed downward against the bottom of the guide track 31 under the action of the elastic stress.

[0045] Since the guiding track 31 extends obliquely in the rotational direction, when the linkage seat 30 rotates in one direction, the linkage rod 42 slides downward along the inclined direction of the guiding track 31. Then, the linkage rod 42 can gradually move downward during the rotation of the linkage seat 30, driving the linkage sleeve 41 to gradually move downward and guiding the heating plate 20 to gradually descend. On the contrary, when the linkage seat 30 rotates in the opposite direction, the linkage rod 42 slides upward along the inclined direction of the guiding track 31. Then, the linkage rod 42 can gradually move upward during the rotation of the linkage seat 30, driving the linkage sleeve 41 to gradually move upward and guiding the heating plate 20 to gradually ascend.

[0046] And since the elastic stress provided by the elastic member 43 can enable the linkage sleeve 41 to maintain a tendency of upward movement, the guiding track 31 can abut against the linkage rod 42 from above. In this way, when the linkage seat 30 rotates, the guiding track 31 can always remain in contact with the linkage rod 42, facilitating the downward guiding of the linkage member during rotation.

[0047] Of course, it is also possible to provide a guiding groove on the linkage seat 30, and the linkage rod 42 can be inserted into the guiding groove. In this way, when the linkage seat 30 rotates in one direction, the upper side wall of the guiding groove can push down the linkage rod 42, and the linkage rod 42 can move downward along the guiding groove. When the linkage seat 30 rotates in the reverse direction, the lower side wall of the guiding groove can push up the linkage rod 42 to guide the linkage rod 42 to move upward. In addition, the above-mentioned guiding groove and guiding track 31 can be selected as a spiral groove or a spiral track, or an inclined groove or an inclined track, and can be specifically selected according to actual needs.

[0048] Furthermore, guiding tracks 31 can be provided on both sides of the linkage seat 30, corresponding linkage rods 42 are provided on both sides of the linkage sleeve 41, and the linkage rods 42 on both sides are in sliding fit with the guiding tracks 31 on both sides of the linkage seat 30 one by one. In this way, when the linkage seat 30 rotates, the guiding tracks 31 on both sides of the linkage seat 30 and the linkage rods 42 on both sides of the linkage member slide one by one, and the guiding forces received on both sides are balanced, so that the lifting movement process of the linkage member is more stable.

[0049] Furthermore, a positioning sleeve 15 can be provided on the mounting base 10, and the above-mentioned linkage seat 30 is rotatably sleeved outside the positioning sleeve 15. On the basis of the structure provided with the positioning sleeve 15, the linkage sleeve 41 of the above-mentioned linkage member is rotatably inserted into the positioning sleeve 15.

[0050] Specifically, a guiding through hole 151 is provided on the positioning sleeve 15, and the guiding through hole 151 extends along the height direction of the mounting base 10. After the linkage sleeve 41 is inserted into the positioning sleeve 15, the linkage rod 42 on the linkage sleeve 41 extends out through the guiding through hole 151 and is in sliding fit with the guiding track 31.

[0051] In this way, when the linkage seat 30 rotates, the linkage seat 30 can rotate relative to the positioning sleeve 15, and the linkage sleeve 41 is assembled based on the inside of the positioning sleeve 15. The linkage rod 42 extends from the guide opening 151 and slides with the guide track 31 during the rotation of the linkage seat 30, so that the linkage rod 42 can move stably up and down in the guide opening 151 under the action of the guide track 31. In this way, the lifting process of the linkage sleeve 41 is guided by the positioning sleeve 15, and the lifting process is stable.

[0052] Furthermore, the mounting base 10 in this embodiment includes a bottom plate 14 and a mounting shell 13, and a mounting cavity is provided in the mounting shell 13. During assembly, the bottom plate 14 covers the bottom end of the mounting cavity, and the bottom plate 14 can be assembled with the bottom end of the mounting shell 13 by screws. Based on this structure, the linkage seat 30 is rotatably installed in the mounting cavity, the heating plate 20 is arranged at the top end of the mounting shell 13, and the linkage member is connected to the bottom end of the heating plate 20 and extends into the mounting cavity.

[0053] Specifically, the linkage seat 30 and the linkage member can be assembled on the bottom plate 14. After assembly, the installation shell 13 is sealed on the outer periphery of the bottom plate 14, so that the linkage seat 30 and the linkage member can be located in the installation cavity, which is convenient for assembly. Of course, a through hole is set at the top of the installation shell 13, so that after the heating plate 20 is assembled on the top of the installation shell 13, the linkage member extends into the installation cavity through the through hole and is linked with the linkage seat 30.

[0054] Furthermore, in order to facilitate the rotation of the linkage seat 30, a rotation opening 12 may be provided on the outer peripheral wall of the mounting shell 13, and a toggle plate 11 may be provided in the mounting cavity, the toggle plate 11 being connected to the linkage seat 30 and extending from the rotation opening 12 to drive the linkage seat 30 to rotate. In this way, when the heating plate 20 needs to be raised or lowered, the toggle plate 11 may be rotated, and the toggle plate 11 slides in the rotation opening 12, which may drive the toggle plate 11 to rotate, and then drive the linkage seat 30 connected thereto to rotate, which is convenient for operation.

[0055] Embodiment 2,

[0056] See also Figures 1 - 8 The present embodiment provides a baby food machine, comprising a machine body 50, a driving assembly, a blending cup 60 and the heating assembly of Embodiment 1. A processing cavity 51 is provided on the machine body 50, the driving assembly is installed on the top of the machine body 50, and the driving shaft of the driving assembly extends into the top of the processing cavity 51, while the mounting base 10 of the heating assembly is provided at the bottom of the processing cavity 51 and connected to the machine body 50; the blending cup 60 can be installed to the processing cavity 51 through the side of the machine body 50.

[0057] When using the baby food machine of this embodiment, the food materials are put into the mixing cup 60, and then the mixing cup 60 is placed in the processing chamber 51 of the machine body. The mixing shaft 61 in the mixing cup can be connected to the driving shaft of the driving structure at the top of the heating chamber, so that the driving structure can drive the mixing shaft 61 in the mixing cup 60 to rotate, and then the mixing blade and other structures on the mixing shaft 61 rotate to stir the material in the mixing cup 60.

[0058] Specifically, before the mixing cup 60 is placed in the machine body 50, the liftable heating component can first be rotated in one direction through the linkage seat 30 of the linkage mechanism. During the rotation of the linkage seat 30, the first guide portion on the linkage seat 30 slides with the second guide portion on the linkage member, so that the linkage member can be guided to move downward, thereby driving the heating plate 20 connected to the linkage member to move downward, and the elastic component 43 is compressed, so that the heating plate 20 is in a low position after falling and will not protrude from the bottom of the machine body 50, making it convenient for the mixing cup 60 to be placed inside the machine body 50.

[0059] After the mixing cup 60 is placed in the machine body 50, the mixing shaft 61 on the mixing cup 60 can correspond to the driving shaft of the driving structure on the machine body 50, and then, it can be reversely rotated through the linkage seat 30. After the linkage seat 30 is reversely rotated, the elastic component 43 is reset, and the elastic component 43 provided can drive the heating plate 20 connected to the linkage member to move upward. At this time, the first guide part and the second guide part slide together to guide the heating plate 20 to move upward synchronously, and the heating plate 20 can be in a high position after being raised, and the mixing cup 60 is lifted upward. The mixing shaft 61 on the mixing cup 60 can be connected to the driving shaft of the driving structure during the lifting process, and then the driving shaft of the driving structure can drive the mixing shaft 61 in the mixing cup 60 to rotate, thereby realizing the stirring action.

[0060] Of course, the elastic stress provided by the elastic component 43 drives the linkage part to move upward, and the elastic stress provided can also keep the linkage seat 30 in an upward trend, so that the first guide part and the second guide part remain in a fit state, which is convenient for sliding cooperation and guiding downward movement during the next rotation.

[0061] It should also be noted that when the blending cup 60 is heated, the blending cup 60 is placed on the heating plate 20. At this time, the heating plate 20 can slide and cooperate with the second guide portion of the linkage member while the first guide portion of the linkage seat 30 is rotating, guiding the heating plate 20 to rise upward, so that a certain distance can be formed between the heating plate 20 and the mounting base 10. During the heating process of the heating element 21 of the heating plate 20, the mounting base 10 will not be too hot during the heating process of the heating element 21 due to the spacing from the mounting base 10, so the body of the device will not be affected by excessive temperature, which complies with safety regulations.

[0062] The heating plate 20 can be lowered to a lower position again under the linkage action of the linkage seat 30 and the linkage member. At this time, the stirring shaft 61 of the stirring cup 60 is disengaged from the drive shaft 71 of the drive structure of the machine body 50, and the stirring cup 60 can be taken out without being interfered by the drive shaft, facilitating the taking and placing of the stirring cup 60.

[0063] The heating component in this embodiment is the same as that in Embodiment 1, and its structure, action process, and action effect applied to the baby food maker are the same as those in Embodiment 1.

It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
