For the convenience of description, the present invention is placed on a horizontal surface and used on a horizontal surface, and "high and low" and "up and down" are defined in this way.

[0052] Example 1

[0053] This embodiment discloses a squeezing element that can be used at least in a tea beverage processing device, and can be used at least for squeezing lemon slices to extract lemon juice.

[0054] like Figures 1 to 3 As shown, the extrusion element 1 includes:

[0055] One end of the rotating shaft 11 is configured to be capable of being transmission-connected to the driving motor 21 of the tea beverage processing device, so that the driving motor 21 can drive the extrusion element 1 to rotate;

[0056] A spiral wall 12 is provided on a side wall of the rotating shaft 11 to define a spiral channel 101 together with the rotating shaft 11. The spiral channel 101 extends from one end of the rotating shaft 11 to the other end.

[0057] The spiral channel 101 includes an inlet end and an outlet end, and the width of the spiral channel 101 gradually decreases from the inlet end to the outlet end.

[0058] Preferably, the spiral channel 101 is opened toward the outside of the side wall of the rotating shaft. The width of the spiral channel 101 refers to the width of the opening of the spiral channel 101. For example, the width of the inlet end is P1, and the width of the outlet end is P2.

[0059] The utility model uses an extrusion element provided with a spiral channel with a gradually varying width to squeeze materials (such as ice cubes and lemon slices) to extract juice. On the one hand, it can be used to extract lemon juice and stimulate the aroma of lemon, and at the same time, larger ice cubes can be crushed. On the other hand, the extrusion element is installed in the tea beverage processing device and is driven by a drive motor to extrude the material, which is not only safe and hygienic but also highly efficient.

[0060] The materials refer to fruits, vegetables, ice cubes and other substances that can be placed in the tea beverage processing device for processing.

[0061] Preferably, the ratio of the width of the inlet end to the width of the outlet end is 1.08 to 3.8, that is, P1 / P2=1.08 to 3.8, so as to ensure that the material is not blocked in the spiral channel while improving the pressurization effect of the material in the spiral channel.

[0062] In order to improve the compactness of the layout of the tea beverage processing device, the inlet end and the outlet end are respectively arranged at one end on each side of the axially opposite sides of the rotating shaft, and the inlet end and the outlet end are relatively far away from each other, that is, the inlet end and the outlet end are respectively arranged on opposite sides of the rotating shaft, and the inlet end and the outlet end are far away from each other, that is, the inlet end is located at one end of the rotating shaft, the outlet end is located at the other end of the rotating shaft, and the opening directions of the inlet end and the outlet end are opposite to each other (for example, the direction of the inlet end is upward, and the opening direction of the outlet end is downward). That is, the rotation angle α of the spiral channel 101 extending from the inlet end to the outlet end is N*360°+180°, where N≥0 and is an integer. In this embodiment, α=180°.

[0063] Preferably, the extrusion element 1 is horizontally arranged in the tea beverage processing device, with the inlet end located at the right end of the side wall of the rotating shaft and the outlet end located at the left end of the side wall of the rotating shaft. In the initial state, the inlet end faces directly upward and the outlet end faces directly downward. This arrangement not only facilitates the entry and exit of materials into and out of the spiral channel, but also makes the layout of the tea beverage processing device more reasonable and compact.

[0064] According to one implementation of this embodiment, the rotating shaft 11 includes a transmission end 111 and an assembly end 112, that is, the two ends of the rotating shaft 11 are respectively the transmission end 111 and the assembly end 112, and the outer side of the transmission end is provided with an inner concave or outer convex structure for transmission connection, and the inner concave or outer convex structure for transmission connection cooperates with the output shaft of the drive motor. Exemplarily, the outer side of the transmission end 111 (the side away from the assembly end 112) is provided with a transmission groove 102, and the transmission groove 102 cooperates with the output shaft of the drive motor 21, that is, the output shaft is inserted into the transmission groove 102 to drive the extrusion element to rotate synchronously with it. The assembly end 112 is rotatably connected to the cooking barrel of the tea beverage processing device. Preferably, the inlet end of the spiral channel 101 is close to the transmission end 111, and the outlet end of the spiral channel 101 is close to the assembly end 112, so as to achieve a better extrusion effect.

[0065] In order to further improve the extrusion effect of the extrusion element on the material, the depth of the spiral channel 101 gradually decreases from the inlet end to the outlet end.

[0066] Preferably, the rotating shaft and the spiral wall are made by integral molding, for example, by integral casting.

[0067] Further preferably, the extrusion element is made of food-grade stainless steel.

[0068] Example 2

[0069] This embodiment discloses a tea beverage processing device, such as Figure 2 Shown, including:

[0070] The main unit 2 includes a drive motor 21;

[0071] The cooking drum 3 includes a cooking chamber 301, one end of which is provided with an output port for the output shaft of the driving motor 21 to pass through;

[0072] The extrusion element 1 described in the first embodiment can be detachably assembled in the cooking chamber 301;

[0073] The transmission end 111 of the rotating shaft 11 is in transmission connection with the output shaft, and the assembly end 112 of the rotating shaft is rotationally connected to the cavity wall of the cooking cavity 301 (the cavity wall is arranged opposite to the cavity wall with the output port).

[0074] It should be noted that the gap between the spiral wall of the extrusion element and the side wall of the cooking chamber 301 is small. Preferably, the gap between the two is not greater than 3 mm. Such a setting ensures that the extrusion element rotates smoothly. On the one hand, it is not easy to be stuck by large particles of pulp, so that the material is always located in the spiral channel as much as possible to ensure the cooking effect of the material; on the other hand, it does not hinder the circulation of liquid in the cooking chamber, and facilitates the self-cleaning operation of the cooking barrel.

[0075] According to one embodiment of the present invention, the tea beverage processing device further includes a feed barrel 4 and a discharge barrel 5 connected to the cooking barrel 3. The cooking barrel 4 is provided with a feed channel 401, which is in communication with the cooking chamber 301 and opposite to the inlet end of the extrusion element 1, allowing material to pass through the feed channel 401 and enter the spiral channel 101. The discharge barrel 5 is provided with a discharge channel 501, which is in communication with the cooking chamber 301 and opposite to the outlet end of the extrusion element 1, allowing material processed by the extrusion element to be discharged from the discharge channel 501 out of the cooking chamber 301.

[0076] In this embodiment, the cooking cylinder 3 is arranged horizontally, and the feed cylinder 4 and the discharge cylinder 5 are both arranged vertically. The center lines of the feed cylinder 4 and the discharge cylinder 5 are parallel, and the center lines of the two are respectively perpendicular to the center line of the cooking cylinder 3. The feed cylinder 4 is located on the right part of the upper side wall of the cooking cylinder 3, and the discharge cylinder 5 is located on the left part of the lower side wall of the cooking cylinder 3.

[0077] The inner sidewall of the cooking drum 3 (i.e., the sidewall of the cooking chamber) is smooth to facilitate cleaning of the tea beverage processing device. Alternatively, the inner sidewall of the cooking drum 3 is provided with a spiral protrusion that cooperates with the spiral channel 101 to seal the spiral channel except for the outlet and inlet ends, preventing fruits and vegetables from overflowing into the spiral channel, improving the squeezing effect of the squeezing element, and enhancing the cooking effect of the tea beverage processing device.

[0078] In order to facilitate the entry of materials into the spiral channel from the inlet end, the feed barrel 4 is provided with a push plug 41 that can be detachably assembled at the inlet of the feed barrel 4, and the push plug 41 cooperates with the feed barrel 4. Specifically, the push plug 41 includes a connected handle portion and a pushing portion, and the pushing portion cooperates with the feed barrel 4 to be inserted into the feed channel 401. Preferably, the length of the pushing portion is not less than the length of the feed channel 401. The handle portion is always located on the outside of the feed barrel 4, and the width of the handle portion is not less than the outer diameter of the feed barrel 4, so that the push plug 41 can be operated by the handle portion, that is, the handle portion can completely cover the feed barrel 4 when projected downward. That is, the shape of the push plug 41 is similar to a "T" shape, the pushing portion constitutes the lower vertical part of the "T", and the handle portion constitutes the upper horizontal part of the "T".

[0079] In order to facilitate the discharge of processed materials out of the cooking chamber, the tea beverage processing device also includes a discharge baffle 31 located in the cooking chamber 301. The discharge baffle 31 is rotatably connected to the assembly end 112 of the rotating shaft 11. Specifically, the discharge baffle 31 is provided with a rotating hole that cooperates with the assembly end 112 of the rotating shaft 11, that is, the assembly end 112 of the rotating shaft 11 can rotate in the rotating hole to improve the rotational stability of the rotating shaft. The position of the discharge baffle 31 cooperates with the discharge barrel 5 to prepare for the material processed by the extrusion element to be discharged from the cooking chamber 301 by the discharge barrel 5. The discharge baffle is provided at the left end of the rotating shaft to push the extruded and crushed food out of the discharge channel. Preferably, a bearing that cooperates with the assembly end is provided in the rotating hole to make the extrusion element 1 rotate more smoothly. In order to facilitate the removal of the extrusion element 1 from the cooking barrel 3, the outer side of the cooking barrel 3 (the side away from the output port) is provided with an end cover 32 that can open or close the cooking chamber, that is, the end cover 32 can open or close the cooking chamber 301. After the end cover 32 is opened, the discharge baffle 31 and the extrusion element 1 can be taken out of the cooking chamber 301 in sequence for maintenance, replacement, and cleaning. When the end cover 32 is closed, its inner side wall constitutes the cavity wall of the cooking chamber 301 opposite to the output port. Exemplarily, the end cover 32 can be installed on the outer side of the cooking barrel 3 in a detachable manner such as threaded connection, clamping, snap connection, magnetic connection, etc. The end cover 32 can also be hinged to the side wall of the cooking barrel 3 at one end and clamped to the side wall of the cooking barrel 3 at the other end to achieve opening or closing of the cooking chamber.

[0080] Preferably, the end cover 32 and the discharge baffle 31 are integrally formed to facilitate removal of the extrusion element 1 .

[0081] For example, the cooking drum 3 (excluding the end caps), feed drum 4, and discharge drum 5 are integrally formed and removably connected to the main unit 2 for ease of maintenance, replacement, cleaning, and transportation. Alternatively, the cooking drum 3, feed drum 4, and discharge drum 5 are integrally formed with the outer shell of the main unit 2 to enhance the structural stability and connection strength of the tea beverage processing device. Alternatively, the cooking drum 3 (excluding the end caps), feed drum 4, and discharge drum 5 can be removably connected to each other, and the cooking drum 3 is further removably connected to the main unit 2 for ease of transportation and maintenance. In actual application, the choice can be made based on specific circumstances.

[0082] To enable the tea beverage processing device of the present invention to achieve a self-cleaning function, the tea beverage processing device also includes a self-cleaning component, which includes a water supply system 6, a water pump 7, and a steam generator 8 connected in sequence. The steam generator 8 has an inlet and an outlet. The inlet is connected to the water supply system 6 through the water pump 7 and a first pipe to pump liquid in the water supply system 6 into the steam generator. The liquid is heated by the steam generator 8 to form high-temperature steam (about 100°C, the boiling point of the liquid). The outlet is connected to the feed channel 401 through a second pipe 81 to guide the high-temperature water vapor generated by the steam generator into the feed channel 401, the cooking chamber 301, and the discharge channel 501, subjecting the components in direct contact with the material to high-temperature treatment, thereby improving food safety and hygiene.

[0083] It should be noted that when the steam generator 8 is not working, it can also form a channel connecting the water pump and the second pipe 81, that is, at this time the water pump can pump the liquid in the water supply system directly into the feed channel 401. In this way, the self-cleaning mode of the tea beverage processing device includes at least two modes: steam sterilization and liquid flushing. In the liquid flushing mode, the steam generator is not working, and the water pump pumps the liquid in the water supply system directly into the feed channel 401, the cooking chamber 301, and the discharge channel 501 for flushing; in the steam sterilization mode, the steam generator is working, and the water pump pumps the liquid in the water supply system into the steam generator to convert it into high-temperature water vapor, which is then introduced into the feed channel 401, the cooking chamber 301, and the discharge channel 501 for high-temperature sterilization. Preferably, when self-cleaning, the tea beverage processing device can choose to first perform the liquid flushing mode and then the high-temperature sterilization mode to achieve a better self-cleaning effect.

[0084] The self-cleaning component can be integrated into the main unit, or can be separated from the main unit, or can be partially integrated into the main unit and partially separated from the main unit. In other words, the water supply system can be configured as a fixed water tank or a detachable water tank or directly connected to a water pipe for water supply.

[0085] In this embodiment, the steam generator 8 and the water pump 7 are located in the housing of the main unit, and the water supply system 6 is configured as a detachable water tank, which is separately provided on the housing of the main unit.

[0086] The water pump is connected to the water supply system through a first pipe, and the water pump is connected to the steam generator through a first pipe; the steam generator is connected to the side wall of the feed barrel 4 through a second pipe.

[0087] Preferably, the second pipe 81 is a hard pipe, and the second pipe 81 extends from the outlet of the steam generator 8 to the outside of the shell of the main machine and is connected to the side wall of the feed barrel 4.

[0088] The first pipeline can be a soft pipe or a hard pipe.

[0089] The tea beverage processing device also includes a control panel 22, which is arranged in the housing of the main unit. The control panel 22 is configured to be electrically connected to at least the drive motor 21, the water pump 7, and the steam generator 8 to control the working progress of the drive motor 21, the water pump 7, and the steam generator 8.

[0090] To achieve a more compact structure and a more rational and stable layout for the tea beverage processing device, an assembly chamber is located near the center of the main unit. The drive motor 21, control panel 22, water pump 7, and steam generator 8 are located within the assembly chamber, with the drive motor positioned above these panels, water pump 7, and steam generator 8, and the water pump below them. The main unit's housing defines a first area at the front for holding a cup 9. This area is located directly below the cooking drum, allowing the cup 9 to be placed directly below the discharging drum to receive the processed material. A second area is defined at the rear for assembling the water supply system. The first and second areas are located on the front and rear sides of the assembly chamber, respectively.

[0091] This tea beverage processing device uses a squeeze element with a gradually varying spiral channel to quickly crush ice and extract lemon juice, stimulating the lemon aroma while also breaking up large ice cubes. The squeeze element is installed within the processing barrel, providing high safety and effectively preventing safety malfunctions caused by accidental operation. The feed barrel is positioned above the squeeze element, while the discharge barrel is located below it, enabling automatic discharging. Furthermore, a self-cleaning component facilitates regular cleaning and disinfection of the device, ensuring safety, efficiency, reliability, and sanitation. This ensures safer and more hygienic prepared food and enhances the device's automation level.

[0092] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
