The orange accessory 2 and the slow squeezing accessory 3 are detachably assembled on the universal stand 1; the micro switch group 15 comprises a first micro switch 151 which is positioned in the middle of the universal base 1 and is used for limiting downwards when the orange function is reset, and a second micro switch 152 and a third micro switch 153 which are positioned on the edge of the universal base and are used for carrying out power-on zero detection and reset on the orange device;

the slow-squeezing accessory 3 comprises a fruit feeding barrel 31, a material pushing rod 32, a filter screen 33, a spiral knife 34, a slow-squeezing cup 35, a slag outlet 36 and a juice outlet 37; the bottom of the spiral knife 34 is provided with a clearance position to avoid the first microswitch 151 with the orange opening function; when the slow squeezing cup is placed for use, the first microswitch 151 is in a normally open state;

when the slow squeezing cup 35 is provided with the universal base, the second microswitch 152 and the third microswitch 153 are simultaneously triggered, and when the slow squeezing function is started to rotate forwards, the whole machine rotates forwards to slowly squeeze juice; when the slow squeezing and reversing function is started, the whole machine reverses so that the residue at the residue outlet can be thrown out, and the juice at the juice outlet flows out.

The orange device 2 comprises a cup cover 21, an orange scraper 22, an orange filter screen 23, an orange cup 24, a screw rod 25, a sleeve 26 and a bottom cover 27; the cup cover 21 is provided with a plurality of orange clamping plates 211, the orange scraper 22 rotates by a screw rod 25 matched with a sleeve 26 to move up and down, and the lower edge of the orange scraper 22 is connected with an orange filter screen 23; the orange cup 24 provides a guide cavity 241 for the screw rod 26 and the sleeve 26, and the bottom cover 27 is covered below the guide cavity 241.

The sleeve cooperates with the orange cup forming a keyway 242 to limit the sleeve from rotating and moving upwardly; when the sleeve 26 moves upwards, the orange filter screen 23 is pushed to move upwards, the orange filter screen 23 moves upwards, and the rotation of the screw rod 26 drives the rotation of the orange scraper 22, so that the orange scraper 22 ascends and rotates to scrape oranges.

The guide chamber 241 is provided with a restricting projection 243. The bottom of the orange cup 24 is provided with a plurality of turnbuckle parts 244 and clearance parts 245 for mounting the universal base 1.

The screw 25 is provided with a polygonal hole; the orange scraper 22 is provided with a handle 221, and the extending length of the handle 221 is larger than the rising height of the sleeve 26 so as to prevent the orange scraper 22 from falling off the screw rod 25 in the rising process.

In the specific implementation and use in combination with the above description and all the drawings, when the orange accessory 2 is screwed, the third microswitch 153 and the orange accessory 2 are kept away from each other, and are not triggered, but the second microswitch 152 is triggered, so that the control board program starts the detection zeroing function. That is, the motor rotates reversely to drive the screw rod 25 to rotate reversely, and the screw rod 25 cannot move upwards under the action of the boss on the cup. Under the action of reverse rotation of the screw rod, because the sleeve 26 is provided with the key and the key slot which are matched with the cup, the sleeve 26 cannot rotate and can only move downwards until the first micro switch 151 under the sleeve is touched, program control is reset to the zero position, and the zero reset action is completed. Under normal conditions, when the return-to-zero detection is started, the first microswitch 151 is automatically triggered when the sleeve is returned, and the motor does not need to be reversely rotated to return to zero.

When the Chinese angelica is in the orange function and the Chinese angelica zero detection is finished, the Chinese angelica is cut into halves and placed on the orange scraper, the cover is covered, the orange function key is started, the motor rotates forwards to drive the screw rod to rotate forwards, and the screw rod cannot move upwards under the action of the limiting boss 243 on the cup. Under the action of the forward rotation of the screw 25, the sleeve 26 cannot rotate but can only move upwards due to the key slot 242 matching the sleeve 26 with the orange cup 24. When the sleeve 26 moves upwards to push the orange filter screen to move upwards, the orange filter screen 23 also pushes the orange scraper 22 to move upwards, and the rotation of the screw rod 25 drives the rotation of the orange scraper 22, so that the orange scraper 22 can rotate while rising. The rising time is set, when the rising time is up, the program can control the motor to switch and rotate reversely, the screw rod 25 is driven to rotate reversely under the reverse rotation of the motor, and the screw rod cannot move upwards under the action of the limiting boss 243 on the cup. Under the action of the reverse rotation of the screw 25, the sleeve 26 cannot rotate but can only move downwards because the sleeve 26 is provided with a key and a key groove which are matched with the orange cup 24. Because the cup cover 21 is provided with the spring, the orange scraper 22 and the orange filter screen 23 can be reset downwards under the action of the spring force while the sleeve 26 is downward. The motor stops rotating reversely until the protruding key slot of the sleeve 26 touches the first microswitch 151 below the bottom, so as to finish the juicing action of orange. And according to the above actions again, completing the juicing actions of a plurality of rounds.

The bottom of the screw rod 25 is a polygonal hole corresponding to the output shaft of the motor, and the polygon has certain guidance, so that the output shaft 13 of the motor and the orange accessory 2 can be conveniently installed and aligned. The upper part of the screw rod 25 is also provided with a polygonal hole, the polygon corresponds to the polygon of the orange scraping handle, and the bottom of the orange scraping handle is also provided with a guide, so that the orange scraping 22 and the screw rod 25 can be conveniently aligned. And the handle of the orange scraper 22 extends into the position with the length larger than the rising height D1-D2 of the sleeve 26, so that the oranges are prevented from falling off the screw rod in the rising process.

The middle of the orange cup 24 is polygonal, and the middle of the orange cup is polygonal and corresponds to the sleeve 26, so that the sleeve 26 can be conveniently positioned and guided in the orange cup 24. The top of the orange cup 24 is provided with a structure which can not move upwards against the screw rod, but the sleeve 26 can move upwards deeply. The orange accessory is an integrated detachable and washable mechanism. When the orange cup needs to be cleaned, the bottom cover is only required to be unscrewed and can be separated from the buckle of the cup, the screw rod 25 and the sleeve 26 can also be detached for cleaning, and the inside of the orange cup 24 can be cleaned. After cleaning, the cleaning agent can be installed back in the original state, and the bottom cover is screwed tightly. When the user does not screw the sleeve 26 and the screw rod 25 in place, the system can also perform the zeroing detection when the system is placed on the host machine, and the resetting function of the sleeve is realized.

When the orange function is used, the orange juice extracting height is D-D1-D2, which corresponds to the corresponding radius of the orange.

Firstly, in the process that the sleeve is driven to move upwards by the motor in the forward rotation mode, an upward L1 is formed within the normally set time t1, when the clamping or other conditions occur, the L2 stroke is completed within the set time t1, and the condition that the mechanism is damaged by jacking due to the fact that the L2 is larger than the L1 occurs, so that the stroke protection in the rising stage is guaranteed because the thread section capable of rising of the screw rod is provided with the stroke L3, and the stroke protection in the rising stage is guaranteed because the L3 is larger than the L2 and is larger than the L1. Secondly, in the process that the motor reversing sleeve moves downwards, the time required from the top end to the bottom is t2 normally, the micro switch can be triggered, but t3 is set in the program, and t3 is greater than t2, so that measures for avoiding damaging other mechanisms are guaranteed under the condition that the micro switch fails or the threads are blocked.

The invention can realize the two-in-one juicer with orange and slow juicing functions by replacing accessories. The universal base 2 is fixed by the motor and does not move, and the lifting juicing and slow juicing functions of orange can be realized by only replacing accessories. The orange accessory 2 can be a juicing mechanism which can automatically lift without being pressed by hands, and the lifting juicing can be circulated for 2 times or more, so that the orange juice can be completely scraped. And the accessory structure can be manually disassembled, cleaned and installed.

When the orange accessory 2 has zero detection, the detection can be automatically carried out and reset in each starting process no matter under the condition of power failure or thread jamming. When the orange accessory 2 has multiple faults or is blocked for protection, firstly, a section of stroke protection is reserved in the ascending stage, and secondly, time protection is set in the descending stage. The upper cover of the orange accessory can also be provided with a spring, and the orange accessory can be better reset and descended by utilizing the elasticity of the spring.
