[0016] Furthermore, the sensing device is a micro switch, which is arranged on the casing near the feed port. When the protective cover closes the feed port, the protective cover touches the micro switch, and the micro switch sends a signal to the circuit board, and the circuit board controls the start and stop of the motor.

[0017] During the juicing process, if the user pushes the protective cover to make it slide and open the feed port, and at the same time the protective cover moves away from the micro switch, the micro switch sends a signal to the circuit board, and the circuit board controls the motor to stop, and the first extrusion part and the second extrusion part stop extruding, thereby preventing the user's hand from reaching into the feed port during the extrusion process, thereby ensuring the user's safety.

[0018] The beneficial effects of the utility model are as follows:

[0019] In the utility model, the protective door maintains the closed juice outlet under the elastic force of the elastic member, thereby preventing the user from accidentally inserting the finger into the juice outlet and preventing the user from being pinched, thereby ensuring the safety of the user.

[0020] In the utility model, the juice receiving bag is suspended and placed in the squeezing area, the juice outlet overcomes the elastic force of the elastic member to push the protection door to rotate, and at the same time the juice outlet extends out of the juice outlet. Due to the blocking effect of the juice outlet, the user is prevented from accidentally inserting his fingers into the juice outlet, thereby preventing the user from being pinched and injured, thereby ensuring the user's safety.

[0021] According to the utility model, during the juicing process, if the user pushes the protective cover to make the protective cover slide and open the feed port, and at the same time the protective cover moves away from the micro switch, the micro switch sends a signal to the circuit board, and the circuit board controls the motor to stop, and the first extrusion part and the second extrusion part stop extruding, thereby preventing the user's hand from being inserted into the feed port during the extrusion process, thereby ensuring the user's safety.

[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0031] Example, combined with Figures 1 to 8 As shown, a safety protection device for a juicer comprises a housing 1, a squeezing device 2, a protection door 3 and an elastic member 4, wherein the squeezing device 2 is arranged in the inner cavity of the housing 1, and comprises a first squeezing portion 21 and a second squeezing portion 22, wherein the first squeezing portion 21 and the second squeezing portion 22 are opposite to each other, and a squeezing area 5 is formed between the first squeezing portion 21 and the second squeezing portion 22;

[0032] The casing 1 is provided with a feed inlet 11 and a juice outlet 12 corresponding to the extrusion area 5. The protection door 3 is rotatably arranged on the casing 1 to close or open the juice outlet 12. The elastic member 4 is arranged on the casing 1, and the elastic member 4 is connected to the protection door 3. The elastic force of the elastic member 4 pushes the protection door 3 to maintain the closed state of the juice outlet 12.

[0033] Furthermore, a rotating shaft 13 is disposed near the juice outlet 12 of the housing 1 , and the rotating shaft 13 is connected to the protection door 3 , and the protection door 3 rotates around the rotating shaft 13 as a rotation center.

[0034] Furthermore, the elastic member 4 is a torsion spring, which is sleeved on the rotating shaft 13 , one end of the torsion spring abuts against the housing 1 , and the other end of the torsion spring abuts against the protection door 3 , and the torsion spring constitutes a reset mechanism of the protection door 3 .

[0035] Furthermore, it also includes a juice receiving bag 6, the top of which is open, and a juice outlet 61 is provided at the bottom of the juice receiving bag 6. The juice receiving bag 6 is suspended and placed in the squeezing area 5, and the juice outlet 61 pushes the protection door 3 to rotate and extend out of the juice outlet 12.

[0036] Furthermore, it also includes a filter bag 10 , which is suspended in the squeezing area 5 and placed in the juice receiving bag 6 .

[0037] Furthermore, a protective cover 7 is included, which is slidably disposed on the casing 1 , and the protective cover 7 slides to close or open the feed port 11 .

[0038] Furthermore, it also includes a sensing device for monitoring whether the feed port 11 is closed. The extrusion device 2 includes an extrusion module 8, a motor 9 and a circuit board (not shown in the figure). The extrusion module 8 includes the first extrusion part 21 and the second extrusion part 22. The extrusion module 8 is connected to the motor 9, and the sensing module and the motor 9 are electrically connected to the circuit board respectively.

[0039] The sensing device is arranged on the casing 1. When the protective cover 7 closes the feed port 11, the protective cover 7 enters the sensing range of the sensing device. The sensing device sends a signal to the circuit board. The circuit board controls the start and stop of the motor 9. The motor 9 controls the first extrusion part 21 and the second extrusion part 22 to move closer to or separate from each other.

[0040] Furthermore, the sensing device is a micro switch (not shown in the figure), which is arranged on the casing 1 near the feed port 11. When the protective cover 7 closes the feed port 11, the protective cover 7 touches the micro switch, and the micro switch sends a signal to the circuit board, and the circuit board controls the start and stop of the motor 9.

[0041] Working principle:

[0042] The user pushes the protective cover 7 to slide and open the feed port 11, and hangs the juice receiving bag 6 and places it in the squeezing area 5. The juice outlet 61 of the juice receiving bag 6 overcomes the elastic force of the torsion spring and pushes the protective door 3 to rotate and extend out of the juice outlet 12. Due to the obstruction of the juice outlet 61, the user cannot put his fingers into the juice outlet 12.

[0043] Next, the user places fruits (eg oranges) in the filter bag 10 , hangs the filter bag 10 in the squeezing area 5 and places it in the juice receiving bag 6 .

[0044] Next, the user pushes the protective cover 7 to slide and close the feed port 11. At the same time, the protective cover 7 touches the micro switch, and the micro switch sends a signal to the circuit board. The circuit board controls the start and stop of the motor 9. The motor 9 controls the first squeezing part 21 and the second squeezing part 22 to move closer to each other to squeeze the fruit (for example, oranges) to extract juice, and the orange juice flows out along the juice outlet 12.

[0045] During the juicing process, if the user pushes the protective cover 7, the protective cover 7 slides to open the feed port 11, and the protective cover 7 moves away from the micro switch, the micro switch sends a signal to the circuit board, and the circuit board controls the motor 9 to stop, and the first squeezing part 21 and the second squeezing part 22 stop squeezing, thereby preventing the user's hand from reaching into the feed port 11 during the squeezing process, thereby ensuring the user's safety.

[0046] During the cleaning process, the protective cover 7 is pushed to slide and open the feed port 11. The user takes out the filter bag 10 and the juice receiving bag 6, causing the juice outlet 61 to leave the juice outlet 12. At this time, the protective cover 7 closes the juice outlet 12 under the elastic force of the torsion spring, preventing the user from accidentally inserting his fingers into the juice outlet 12, thereby ensuring the user's safety.
