Among them, "up" and "down", "left" and "right", "front" and "rear" are opposite directions.

[0046] In the description of the present utility model, it is necessary to understand that the technical features defined by the terms "first", "second", "third" and the like with sequential concepts are only for the purpose of clearly describing the defined technical features so that the defined technical features can be clearly distinguished from other technical features, but do not represent such naming in actual implementation, and therefore cannot be understood as a limitation of the present utility model.

[0047] The present invention is described in detail below in conjunction with specific embodiments and drawings.

[0048] Figures 1 to 5 , Figure 7 An ice cream machine including the ice cream stirring and extruding mechanism of the utility model is shown, and the ice cream machine includes a body 100, an inner tank 200, a stirring member 300, an extruding member 400, a front cover member 500, a feeding member 510, a discharging member 520, a discharging valve assembly 530, a motor 600, a refrigeration device and a heat preservation cover 101.

[0049] The fuselage 100 is the basis of the whole ice cream machine, and is used to install and carry other structures of the ice cream machine. Generally, the fuselage is an assembly structure, so as to assemble other structures of the ice cream machine.

[0050] The inner liner 200 is preferably made of aluminum to meet food hygiene requirements and have good thermal conductivity. The inner liner 200 is fixed horizontally in the fuselage. The inner liner 200 is cylindrical and has an opening 201 at its front end and is closed by a rear wall 202 at its rear end. The opening 201 corresponds to the opening 102 at the front side of the fuselage. The rear wall 202 of the inner liner is provided with a guide wheel 203 located on the same circumference. The rear wall 202 of the inner liner is provided with a through hole.

[0051] The refrigeration device is used to provide coldness to the inner tank, and keep the inner tank at a relatively low temperature so as to cool down the ice cream puree added to the inner tank into ice cream that can be output from the discharge port. The refrigeration device can be a compressor refrigeration device, an electronic refrigeration device, or a refrigeration device of other structural forms, which is not limited by the present invention. The cold output end of the refrigeration device contacts the inner tank to provide coldness for the inner tank. In order to keep warm and avoid the loss of coldness, a heat preservation cover 101 is provided in the body 100, the inner tank 200 is located in the heat preservation cover 101, and the space between the heat preservation cover and the inner tank is filled with heat preservation material.

[0052] The stirring member 300 is disposed transversely to the inner pot 200. The stirring member 300 includes an inner end support ring 301, an outer end support ring 302 and a stirring blade 303. The stirring blade 303 is connected between the inner end support ring and the outer end support ring so as to rotate along the cylindrical inner wall of the inner pot with the inner end support ring and the outer end support ring. The stirring blade 303 is distributed at intervals in the circumferential direction of the inner end support ring and the outer end support ring. Figure 6 There are two stirring blades in the structure. Figure 6 , Figure 8 As shown, the inner end support ring 301 includes two axially spaced ribs 304, and an internal gear 305 is provided between the two ribs. Moreover, the guide wheel 203 is supported on the circumferential surface 306 of the two ribs to ensure the rotation of the stirring member and the assembly relationship with the inner pot. The outer end support ring at the front end of the stirring member 300 extends into the blind hole portion of the front cover member 500 to achieve radial support of the stirring member by the front cover member and rotational cooperation with the front cover member. Moreover, the stirring member 300 is axially limited between the front cover member 500 and the rear wall 202 of the inner pot to limit the axial movement of the stirring member when it rotates.

[0053] The extrusion member 400 is disposed transversely at the bottom of the inner container 200 , and the axis 405 of the extrusion member is parallel to the axis 307 of the stirring member. Figure 6The extrusion member in the embodiment is composed of spiral wing plates 402 distributed continuously on the shaft 401. Therefore, when the extrusion member rotates in one direction around its axis, the spiral wing plates can squeeze and push the ice cream in the inner container to the discharge channel. In order to transmit power, the rear end of the extrusion member 400 is provided with an external gear 403. The external gear 403 and the internal gear 305 form a pair of gear pairs, and accordingly, the external gear and the internal gear mesh to realize the transmission of the extrusion member and the stirring member. Moreover, the number of teeth of the internal gear is greater than the number of teeth of the external gear. When the extrusion member and the stirring member are transmitted through the gear pair, the angular velocity of the extrusion member is greater than the angular velocity of the stirring member, so that when the extrusion member quickly extrude the ice cream, the stirring member slowly stirs the ice cream and stirs the ice cream in the inner container evenly. The rear end of the extrusion member 400 extends backward from the inner container through the through hole of the rear wall 202 of the inner container to connect with the motor 600 to receive power. Preferably, in order to facilitate connection and disassembly, the rear end of the extrusion member and the motor are preferably matched by splines. Furthermore, the rear wall 202 of the inner container and the extruded member 400 are sealed by a sealing member 404 squeezed therebetween.

[0054] The front end of the extrusion member 400 is inserted into the hole of the front cover member 500 like a shaft to realize that the extrusion member is radially supported by the front cover member and rotates with the front cover member. The extrusion member 400 is axially limited between the front cover member 400 and the rear wall 202 of the inner liner to limit the axial movement of the extrusion member when rotating.

[0055] The profile of the opening 201 is larger than the profile of the extruded member 400 and the profile of the stirring member 300, which is reflected in that the axial projection profile of the opening 201 is larger than the axial projection profile of the extruded member 400 and the axial projection profile of the stirring member 300, so that the stirring member 300 and the extruded member 400 can be taken out of the inner container through the opening 201 and loaded into the inner container through the opening.

[0056] The front cover member 500 , the charging member 510 , the discharging member 520 and the discharging valve assembly 530 are assembled into one body.

[0057] In the illustrated structure, the front cover member 500 is cylindrical and is detachably assembled on the front side of the body 100 through a snap-fit ​​structure. Figure 4-5 and Figure 7 As shown, the left and right sides of the inner cavity of the front cover member 500 are each equipped with a rod-shaped lock buckle 502 extending forward and backward through a spring sheet 501, and the rear end of the rod-shaped lock buckle has an outward hook 503, which protrudes from the outer wall of the front cover member through a through hole. When the front cover member 500 is pushed back in correspondence with the inner liner, the hooks 503 of the two rod-shaped lock buckles can hook the fuselage 100, thereby assembling the front cover member to the fuselage, and the rear end of the front cover member 500 and the edge of the opening 201 of the inner liner are sealed by a first sealing ring 504. When the front cover member is to be removed, as shown in FIG. Figure 5By pressing the front end of the rod-shaped member in the direction indicated by the arrow in the figure, the hook 503 is disengaged from the body, and the front cover member can be removed from the body. Figure 7 As shown, when the front cover member is removed from the front side of the body, the opening 201 of the inner container is exposed so that the stirring member and the extruding member can be taken out for cleaning and the inner container can be cleaned.

[0058] The feeding component 510 is provided with a feeding channel 511, and the feeding channel 511 has an upward feeding port 512. The feeding component is assembled to the front cover component by sliding insertion. The feeding component can be first assembled to the front cover component and then assembled to the fuselage together with the front cover component, or the front cover component can be first assembled to the fuselage and then the feeding component can be assembled to the front cover component. During disassembly, the feeding component can be first removed from the fuselage together with the front cover component and then the feeding component can be removed from the front cover component, or the feeding component can be first removed from the front cover component and then the front cover component can be removed from the fuselage. In the assembled state, the feeding channel 511 is located at the front side of the fuselage and connected to the upper part of the opening 202 of the inner tank, and the rear end of the feeding component and the front cover are sealed by a second sealing ring 513.

[0059] The discharging member 520 is provided with a discharging channel 521, and the discharging channel has a discharging port 522 deflected downward. The discharging member is assembled to the front cover member by sliding insertion. In the illustrated structure, the discharging member can be first assembled to the front cover member and then assembled to the fuselage together with the front cover member, or the front cover member can be first assembled to the fuselage and then assembled to the front cover member. During disassembly, it is inconvenient to press the rod-shaped lock due to the obstruction of the discharging member. Therefore, it is advisable to remove the discharging member from the front cover member first and then remove the front cover member from the fuselage. In the assembled state, the discharging channel 521 is located at the front side of the fuselage and connected to the open lower part of the liner, and the rear end of the discharging member and the front cover are sealed by a third sealing ring 523.

[0060] The discharge valve assembly 530 includes a valve plug 531, a connecting rod 532 and a handle 533. The valve plug is located in the discharge channel 521 like a piston and can move forward and backward. Figure 3 When the valve plug moves to the rear end of the discharge channel, the discharge channel is closed. Figure 4 When the valve plug moves to the front end of the discharge channel, the discharge channel is opened, and the ice cream from the inner container is discharged through the discharge channel and the discharge port in the direction indicated by the arrow in the figure. The handle 533 is provided with a cam 534. The rear end of the connecting rod 532 is connected to the valve plug, and the front end of the connecting rod is rotated to connect to the cam 534. By turning the handle, the cam and the connecting rod move with the valve plug in the discharge channel to open or close the discharge channel. Fig. 9As shown, for sealing, the valve plug 531 integrally extends a sealing sleeve 535 toward the handle, and the front end of the sealing sleeve is squeezed by the end cover 536 at the front end of the discharge channel 521 to achieve sealing. Preferably, the valve plug and the sealing sleeve are made of silicone. In view of the assembly relationship between the discharge valve assembly and the discharge channel, the discharge valve assembly and the discharge member are integrally assembled on the front cover member or removed from the front cover member.

[0061] In order to ensure the assembly relationship between the feed component 510 and the discharge component 520 and the front cover component 500, the discharge component is provided with a pin 524, and the front cover component is provided with a bayonet 505. When the discharge component is assembled to the front cover component, the pin and the bayonet are clamped together. The feed component 510 is pressed by the decorative cover 540 clamped on the discharge component 520 and is kept in the assembly position. The clamping of the decorative cover and the discharge component can adopt the same clamping structure of the discharge component and the front cover component. In other embodiments, the feed component can also be directly clamped on the front cover component.

[0062] The inner pot, extrusion member and stirring member can be cleaned without disassembling the front cover member, the feeding member and the discharging member. At this time, water is added to the inner pot through the feeding port, the extrusion member and the stirring member are rotated, and the discharging channel is opened to release the water in the inner pot. This process is repeated to achieve cleaning.

[0063] The ice cream machine adds the prepared ice cream puree into the inner tank through the feeding port, and the refrigeration device cools the ice cream inner tank to a low temperature to make ice cream. After the ice cream is made, the discharge channel is opened, and the ice cream is slowly pushed out of the machine by the extrusion component to complete the making. Since the feeding port and the discharge port are both located at the front side of the machine body and kept close to each other, it is convenient to add and receive materials during use, and the height of the equipment is reduced.

[0064] When cleaning is required, the front cover component is disassembled from the body, and the extrusion component and the stirring component can be taken out from the opening of the inner container. Similarly, the extrusion component and the stirring component are installed back into the inner container from the opening of the inner container, and then the front cover component, the feeding component and the discharging component are installed.

[0065] The inner container, the stirring component and the extruding component of the utility model are arranged transversely, which means that their axes are arranged horizontally when in use.
