In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Fig. 1-7 schematically show the construction of an ice cream maker according to the invention.

Referring to fig. 1 to 7, an ice cream maker 100 according to the present invention includes:

a base 1;

the barrel body 2 is arranged on the base 1 and comprises a first barrel body 21 and a second barrel body 22 which are sequentially arranged from inside to outside, a first cavity 2a is arranged between the first barrel body 21 and the second barrel body 22, a second cavity 2b is arranged inside the first barrel body 21, the first cavity 2a and the second cavity 2b are respectively used for containing cold storage agent and ice cream raw materials, and the first barrel body 21 and the second barrel body 22 are in sealing fit;

the stirring piece 4 is arranged in the first barrel body 21 and is used for stirring ice cream raw materials; and

the driving mechanism 5 is used for driving the stirring part 4 to rotate and comprises a power mechanism and a rotating shaft 51, and the power mechanism is in driving connection with the stirring part 4 through the rotating shaft 51;

wherein, power unit sets up on base 1, is equipped with through-hole 24 on the diapire of first staving 21, and pivot 51 inserts in first staving 21 through-hole 24 to with the sealed cooperation of first staving 21.

In the above arrangement, the driving mechanism 5 is in driving connection with the stirring part 4, and the stirring part 4 is driven to rotate, so that the relative rotation of the stirring part 4 and the barrel body 2 is realized. Since the rotational moment required for driving the stirring element 4 to rotate is smaller than in the case of driving the barrel 2 to rotate, the driving mechanism 5 can have a smaller size and lower power, which is beneficial to reducing the overall size of the ice cream machine 100 and the overall power of the ice cream machine 100.

Meanwhile, the power mechanism of the driving mechanism 5 is arranged on the base 1, so that the driving mechanism 5 is arranged at the bottom, and the space of the upper part is not required to be occupied, and the feeding is convenient.

It can be seen that the ice cream machine 100 is configured to have the structure that the driving mechanism is arranged at the bottom and the stirring member rotates, which is beneficial to improving the feeding convenience and reducing the overall dimension.

In addition, in above-mentioned setting, the pivot 51 of drive connection power unit and stirring piece 4 inserts in first staving 21 via through-hole 24 on the first staving 21 diapire for need not too much structure or too much air in interval between ice cream raw materials and the cold-storage agent, consequently, be favorable to realizing more directly more fully exchanging heat between ice cream raw materials and the cold-storage agent, improve heat exchange efficiency, accelerate ice cream preparation speed.

In the above setting mode, because sealed cooperation between first staving 21 and the second staving 22, and sealed cooperation between pivot 51 and the first staving 21, consequently, can prevent effectively that coolant, ice cream raw materials and the ice cream that makes from taking place to reveal, realize safer processing manufacture process, reduce the risk of taking place the food safety problem.

In order to realize the sealing between the first tub body 21 and the second tub body 22 to prevent the leakage of the coolant, at least one of a welding seal, an adhesive seal, and a gasket seal may be used to seal between the first tub body 21 and the second tub body 22.

For example, referring to fig. 2-3, in some embodiments, the ice cream maker 100 includes a first gasket 61, and the first gasket 61 is disposed between the bottom wall of the first bucket body 21 and the second bucket body 22, and is used for sealing the bottom wall of the first bucket body 21 and the second bucket body 22. Specifically, as can be seen from fig. 3, in some embodiments, the first sealing gasket 61 is disposed below the lower end surface of the through hole 24 and surrounds the periphery of the through hole 24. The rotation shaft 51 is inserted into the first tub 21 through the through hole 24 after passing through the first gasket 61. Based on this, a sealing gasket is used between the bottom of the first barrel body 21 and the second barrel body 22.

It should be understood that the manner of sealing between the bottom of the first tub 21 and the second tub 22 is not limited to the above-described gasket sealing manner. For example, as a modification, the first gasket 61 may be replaced by glue, that is, the first gasket 61 is not arranged at the position where the first gasket 61 is arranged, but glue is applied instead, and the bottom wall of the first barrel 21 and the second barrel 22 are adhered by the glue to realize the adhesive seal between the bottom wall of the first barrel 21 and the second barrel 22. Alternatively, referring to fig. 7, in other embodiments, the bottom wall of the first barrel 21 is welded to the second barrel 22, so that the bottom wall of the first barrel 21 is sealed to the second barrel 22 by welding.

In addition to sealing the bottom wall of the first tub 21 with the second tub 22, in some embodiments, the top of the first tub 21 and the second tub 22 are also sealed.

For example, referring to fig. 6, in some embodiments, the ice cream maker 100 includes a second gasket 62, and the second gasket 62 is disposed on the top of the first and

second tubs

21 and 22 for sealing the top of the first and

second tubs

21 and 22. At this time, the tops of the first and

second tub bodies

21 and 22 are sealed in a gasket manner.

For another example, referring to fig. 7, in other embodiments, the tops of the first and

second tub bodies

21 and 22 are welded, such that the top of the first tub body 21 and the top of the second tub body 22 may be sealed by welding.

For another example, although not shown, in other embodiments, the tops of the first barrel 21 and the second barrel 22 are connected by glue, so as to achieve an adhesive seal therebetween.

When a sealing gasket sealing manner is adopted between the first barrel body 21 and the second barrel body 22, referring to fig. 1-2 and fig. 6, in some embodiments, the ice cream machine 100 further includes a top cover 3 and a fastening member 71, the top cover 3 is disposed at the top of the barrel body 2, and the fastening member 71 fastens the second barrel body 22 and the top cover 3. Specifically, as shown in fig. 2 and 4, in some embodiments, a boss 26 is formed on an upper portion of an inner wall of the second tub 22, and a fastening member 71 is inserted into the boss 26 to fasten the second tub 22 and the top cover 3. The top of the first barrel body 21 extends between the boss 26 and the top cover 3.

Based on the above arrangement, under the fastening effect of the fastening piece 71, the top cover 3 can extrude the sealing gasket between the first barrel body 21 and the second barrel body 22, so that the sealing gasket between the first barrel body 21 and the second barrel body 22 is deformed under pressure, and a better sealing effect is realized. For example, in the case where the first gasket 61 is provided between the first tub 21 and the second tub 22, the lid 3 may press the first gasket 61 through the first tub 21 under the fastening action of the fastening member 71, that is, the lid 3 presses the first tub 21 under the fastening member 7, and then presses the first gasket 61 through the first tub 21, so as to increase the deformation of the first gasket 61. For another example, in the case where the second gasket 62 is provided between the first tub 21 and the second tub 22, the top cover 3 may press the second gasket 62 by the fastening action of the fastening member 71, increasing the deformation of the second gasket 62.

In the above setting mode, because fastener 71 sets up at the top of staving 2, and the bottom of non-staving 2, can reduce fastener 71 to the taking of staving 2 bottom space, consequently, be favorable to increasing the heat transfer area between first staving 21 bottom and the second staving 22, promote heat exchange efficiency for ice cream preparation efficiency.

In addition, in order to achieve sealing between the rotating shaft 51 inserted into the first barrel 21 and the first barrel 21, referring to fig. 3, in some embodiments, the ice cream machine 100 includes a sealing ring 63, the sealing ring 63 is disposed between the rotating shaft 51 and the through hole 24, and the rotating shaft 51 is in sealing fit with the first barrel 21 through the sealing ring 63. In this way, the sealing ring 63 seals the gap between the shaft 51 and the through hole 24, preventing the ice cream material or the prepared ice cream in the first chamber 2a from leaking through the gap between the shaft 51 and the through hole 24.

Wherein, the sealing ring 63 may be disposed between the rotating shaft 51 and the through hole 24 in an interference manner. Based on this, even if the rotation shaft 51 rotates all the time and rubs against the seal ring 63, the seal ring 63 can achieve effective sealing, and leakage of the ice cream material or the prepared ice cream at the through hole 24 can be reliably prevented.

In order to fix the rotating shaft 51, referring to fig. 3 and 4, in some embodiments, the ice cream maker 100 further includes a connecting member 73, the rotating shaft 51 is connected to the barrel 2 through the connecting member 73, and the connecting member 73 allows the rotating shaft 51 to pass through from bottom to top and limits the displacement of the rotating shaft 51 from top to bottom. On the basis, on one hand, the connection piece 73 does not influence the upward insertion of the rotating shaft 51 into the barrel body 2, and can still conveniently realize the insertion of the rotating shaft 51 from bottom to top, and on the other hand, the connection piece 73 can prevent the rotating shaft 51 from falling downwards after the rotating shaft 51 is inserted, so that the reliable limit of the rotating shaft 51 is realized. It can be seen that the connecting member 73 is provided to facilitate the insertion of the rotating shaft 51 into the barrel 2 from bottom to top, and prevent the rotating shaft 51 from falling out. Simultaneously, the connecting piece 73 that sets up need not to occupy the space of first staving 21 diapire, is favorable to the area of contact maximize with first staving 21 diapire and ice cream raw materials, increases bottom heat exchange efficiency.

Specifically, referring to fig. 4, in some embodiments, a tapered cavity 733 and a limiting cavity 734 are disposed in the connecting member 73 and sequentially communicate from bottom to top. The cross-sectional area of the tapered cavity 733 decreases from bottom to top. The cross-sectional area of the bottom end of the confinement chamber 734 is greater than the cross-sectional area of the top end of the tapered chamber 733 such that the junction of the confinement chamber 734 and the tapered chamber 733 forms a step 735. Shaft 51 includes a shaft body 511 and an axon 512, and axon 512 is located between both ends of shaft body 511 in the axial direction and projects from shaft body 511 toward the radial outside. Axis body 511 passes through tapered cavity 733 and limiting cavity 734, and axon 512 presses against step 735. Based on this, the connecting piece 73 forms a one-way dead-lock structure, so that when the rotating shaft 51 is inserted from bottom to top, the connecting piece 73 is squeezed, the tapered cavity 733 is deformed outwards, expansion occurs, and the insertion of the rotating shaft 51 is smoothly realized, and after the rotating shaft 51 is inserted, if the rotating shaft 51 is pulled downwards, the step 735 limits the axon 512, even the tapered cavity 733 is deformed inwards, narrowing occurs, and the rotating shaft 51 is prevented from being pulled downwards.
