Description

  The present invention relates to a device for squeezing or mincing vegetables and fruits to make juice, and more particularly to a safety device for a juicer that ensures operational safety for the user.

  Most juicers on the market now have a material entry tunnel in the fuselage. A material pusher is placed in the material entry tunnel, and the user throws vegetables and fruits into the material entry tunnel, which causes the vegetables and fruits to fall onto a disk cutter at the bottom of the material entry tunnel. The material pusher presses vegetables and fruits, and at the same time, uses a cutter to chop and grind vegetables and fruits into juice.

  A known juicer controls the operation of the motor by means of a switch. That is, when the switch is turned on, the motor continues operation and drives the continuous rotation of the cutter. On the other hand, when the switch is turned off, the motor and the cutter stop rotating simultaneously. This type of design has the following disadvantages: When the material pusher leaves the material entry tunnel, but the next vegetable or fruit is not yet put, the cutter is still in rotation, so if a foreign object enters the material entry tunnel, May be damaged by strong impacts, and even foreign objects may be thrown out of the aircraft, causing injury to people nearby. Before the user pushes out the material pusher from the material entry tunnel, the user can first turn off the power and then turn on the power again when vegetables and fruits are turned on again. However, such repeated operations are very inconvenient. is there.

  Similarly, conventional juicers that do not include a material pusher have safety issues as well. In particular, the fact that the opening of the juicer's fuselage is relatively large and easily accessible by the child is a very dangerous and serious drawback.

  On the other hand, patent document 1 posts the design which solves the problem of the above-mentioned conventional juicer. However, in Patent Document 1, since the switch device is installed in the material entry tunnel, there is a possibility that vegetable or fruit juice may permeate into the switch device, or the quality of vegetables or fruits may be contaminated by the switch device. It is not easy. Further, in Patent Document 1, when the material pusher reaches a certain depth of the material entry tunnel, it is designed to contact the switch device and turn on the power, so that the material pusher is lifted and leaves its depth. Then, the power is turned off without touching the switch device. That is, there is no freedom in starting the power source, and the user cannot control the timing of motor operation according to the actual situation. The present invention has been made in view of the above-mentioned drawbacks of the conventional juicer safety device.

U.S. Patent No. 11/620801

  The main problem to be solved by the present invention is to provide a juicer safety device that improves the degree of freedom of motor startup and can meet higher hygiene requirements.

In order to solve the above-mentioned problems, the present invention provides the following juicer safety device.
Juicer's safety device is equipped with a fuselage and a material pushing cylinder, a switch device is installed outside the material entry tunnel, and a safety ring is combined with the material pushing cylinder in a movable state.
When the material pushing cylinder is inserted into the material entry tunnel, the material pushing cylinder activates the motor power, and the safety ring is operated to control the power on and off. It is freely controllable and very convenient to operate, and the hygiene concerns due to the installation of the switch device in the material entry tunnel can be eliminated.
Since the safety ring has an appropriate weight, when the material push-in cylinder is inserted into the material entry tunnel, the safety ring falls by itself, interlocks the switch device, activates the power supply, or a little later. The safety ring can be dropped to delay power activation.
When the material pushing cylinder is lifted, the safety ring is also lifted at the same time, the power supply is cut off, and only the material pushing cylinder is lifted, and the safety ring can be kept in its original position and maintained in the energized state.
A switch device is installed outside the material entrance tunnel, the switch device is electrically connected to the power source of the motor, and the outer periphery of the material pushing cylinder can be moved relative to the material pushing cylinder in the axial direction. Install a ring, and include an object of appropriate weight inside the safety ring, increase the overall weight of the safety ring, and install a protruding part under the safety ring that can contact the switch device To do.
When the material push-in cylinder enters the material entry tunnel, and the safety ring covers the material entry tunnel and the projecting part contacts the switch device, the motor is energized and the operation of the cutter device is interlocked. .
When the safety ring is moved upward and the projecting parts and the switch device are separated, the motor is turned off and the cutter device stops operating.
A handle is installed outside the material entry tunnel, the switch device is installed inside the handle, and a vertically extending slot is installed at the upper end of the handle, and the switch device is formed on the inner wall of the slot. When exposed and this causes the protruding part below the safety ring to be inserted into the slot, it can contact the switch part and activate the power supply.
The switch device in the handle includes an inching switch and a connecting rod that is movably installed inside the handle. The connecting rod is exposed to the inner wall of the slot, and the protruding part below the safety ring is the slot. When the rod is inserted, it directly contacts the connecting rod, and the inching switch is interlocked by the connecting rod to start the power supply.
In a situation where the operation of the cutter device must be continued, a through-hole penetrating in the axial direction at the upper and lower ends is installed in the material pushing cylinder, and a material pushing rod is inserted into the through-hole in a movable state in the axial direction. As a result, the material push-in cylinder is kept inserted in the material entry tunnel, and relatively small volumes of vegetables and fruits are introduced through the through-hole, and the material push-in rod is used to Vegetables and fruits can be made into juice by inserting them into the through holes.

  The present invention can ensure the operational safety of the user.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1 and FIG. 3, a juicer safety device according to an embodiment of the present invention includes a juicer body 1 and a material pushing cylinder 4. A material entry tunnel 11 is installed on the machine body 1, and a cutter device 12 is installed below the material entry tunnel 11. A motor 16 is connected to the lower side of the cutter device 12, and when the motor 16 is energized and operated, the rotation of the cutter device 12 can be driven. In this way, the vegetables and fruits input from the material entry tunnel 11 are used as juice, and the juice flows out from the juice outlet 13 on the side of the machine body 1. On the other hand, the residue of vegetables and fruits is discharged to the residue collection tank 14.

  Next, as shown in FIG. 3 and FIG. 4, the juicer safety device according to an embodiment of the present invention has a handle 15 installed outside the material entry tunnel 11 of the fuselage 1. A slot 151 that extends vertically and has an appropriate depth is provided on the upper surface of the handle 15. A switch device is installed inside the handle 15. The switch device includes an inching switch 2 and a connecting rod 3. The inching switch 2 is electrically connected to the power source of the motor 16. The connecting rod 3 is movably installed inside the handle 15, and one end of the connecting rod 3 contacts the inching switch 2.

  As shown in FIGS. 2 and 4, the material push-in cylinder 4 of the juicer safety device according to the embodiment of the present invention is provided with a through hole 43 penetrating in the axial direction. A plurality of introduction grooves 45 extending in the axial direction are provided on the outer peripheral surface of the material pushing cylinder 4. A safety ring 41 is combined with the outer periphery of the material pushing cylinder 4 in a movable state. On the inner diameter of the safety ring 41, an introduction block 411 corresponding to the introduction groove 45 and slide is installed. As a result, the safety ring 41 moves relative to the material pushing cylinder 4 in the axial direction, but cannot perform relative rotation. Further, a protruding part 42 that can be inserted into the slot 151 at the upper end of the handle 15 is installed below the safety ring 41. A material pushing rod 44 can be pushed into the through hole 43. Inside the safety ring 41, components having an appropriate mass such as a metal block can be installed, thereby increasing the weight of the safety ring 41 as a whole. Alternatively, the safety ring 41 can be manufactured by using an appropriate material, and can be a safety ring 41 having an appropriate weight.

  Then, the usage method of this invention is demonstrated. After the vegetables and fruits are put into the material entry tunnel 11, the material push-in cylinder 4 is inserted into the material entry tunnel 11, but the safety ring 41 has a certain weight, so that it stays at a position below the material push-in cylinder 4, so that the material In the process in which the pushing cylinder 4 enters the material entry tunnel 11, the safety ring 41 falls by itself. Accordingly, the protruding component 42 is inserted into the slot 151 at the upper end of the handle 15 and comes into contact with the connecting rod 3. The connecting rod 3 is energized in conjunction with the inching switch 2 (see FIG. 5). In the process in which the material pushing cylinder 4 continues to move downward, after the material pushing cylinder 4 is completely inserted into the material entry tunnel 11, the protruding component 42 also keeps contact with the connecting rod 3. As a result, the motor 16 is energized and is in an operating state (see FIG. 6). When the user wants to turn on the power, the user can start the power by holding the safety ring 41, inserting the material pushing cylinder 4 into the material entry tunnel 11, and lowering the safety ring 41 downward. After the safety ring 41 is moved upward, and the protruding part 42 leaves the contact with the connecting rod 3, the connecting rod 3 can be returned to the original position by the elasticity of the inching switch 2 itself. There are roughly the following two methods for moving the safety ring 41 upward. One is a system in which the safety ring 41 is lifted at the same time when the material pushing cylinder 4 is lifted upward, and the power is cut off at the same time. The other is that when it is not desired to immediately turn off the power, only the material pushing cylinder 4 is lifted upward, and the safety ring 41 maintains the original position covering the upper end of the material entry tunnel 11, thereby The motor 16 continues energization and continues operation.
