Description

The present invention relates to a kind of electrostatic induction trash can cover, and more particularly to an induction trash can cover with a large induction area.

The conventional trash can cover needs to be opened manually by the user. However, the operation of pulling up the trash can cover may touch the filth, and the hand must be washed immediately so as not to leave the trash cover virus, germs or filth in the hand.

After that, a pedal-type trash can is proposed, and the trash can cover is lifted by stepping on the pedal with your foot. Because it can be operated with your feet, you do not have to worry about sanitary problems by touching the trash can cover. Furthermore, since the foot is wearing shoes and slippers, there is no worry of touching the trash can cover directly.

However, pedal-type trash cans are not suitable for users who are injured by the foot and in some situations. First, people with injuries on their feet or inconvenient behavior cannot use pedals in pedal-type trash cans, so pedal-type trash cans are not suitable for these people. In addition, there are many places where the trash can is placed in a small space, and it is hard to accommodate the trash can in the corners of the customers or in the kitchen cabinet, and there are many places where the user cannot step on.

For this reason, induction-type trash cans have been proposed. There are mainly two types of guidance methods for the current induction type trash can: infrared induction method and electrostatic induction method. The infrared induction method requires a sensor device and can only detect one point. That is, the user can bring his hand close to the sensor device, the temperature of the hand is detected by the sensor device, and the trash can cover can be opened. However, the infrared guidance method has a drawback that the lifting control of the trash can cover cannot be performed unless the user is aiming at the sensor device. When the sensor device is attached in the opposite direction of the user, the raising of the trash can cover cannot be controlled unless the user intentionally turns to the front of the sensor device and aims at the sensor device. Further, if the direction of the trash can placed in the corner or built in the cabinet is changed, the user must return the trash can to a predetermined position before throwing in the trash. Since this method is troublesome, the infrared induction method is not a kind design.

At present, an induction coil is attached to an electrostatic induction type that is often seen, and an area surrounded by the induction coil has a function of electrostatic induction. Compared with the infrared induction method, a wider detection area can be obtained. However, there has been a need to provide a static induction type trash can cover that improves the detection area that can be provided by only the induction coil, is convenient for the user, and can lift the trash can cover without bringing the trash can close to the side.

The main technical means of the present invention is that two induction coils are provided in two ring portions each having a step so that a larger induction area is secured, there is no blind spot in the induction area, and a better detection effect is provided. Can automatically rotate the flip cover.

According to the next technical means of the present invention, electrostatic induction can be received from all angles by providing two induction coils on the trash can cover, and an automatic rotation effect of the flip cover can be provided.

Another technical means of the present invention is that the elastic member assists the rotation of the interlocking device to reduce the load of the actuator rotation, and the actuator does not require a large load, so it can maintain a longer service life, Actuators do not have a risk of accidental tooth breakage due to large torque.

According to still another technical means of the present invention, the user can select the rotation operation of the flip cover by manual operation or electrostatic induction by a switch operation.

From the following description, the present invention can summarize the following advantages.

<A> The electrostatic induction type trash can cover according to the present invention provides a detection area with a large detection range by providing two induction coils on two stepped ring parts, respectively, and there is no blind spot in the detection area.

<B> The electrostatic induction type trash can cover of the present invention can receive the electrostatic induction at all angles and rotate the flip cover by installing two induction coils on the flip cover.

<C> The flip cover of the electrostatic induction trash can cover of the present invention is lifted from the base and the cover body, and the elastic member assists the rotation of the interlocking device, thereby reducing the load of the actuator rotation, and the actuator has a large load. Therefore, it is possible to maintain a longer service life, and there is no fear that the actuator will break down due to a large torque operation.

FIG. 10 and FIG. 11 are diagrams showing how the flip cover is pulled up from the base and the cover body by the electronic control device of the present invention. The first and second induction coils 46 and 47 of the present invention are attached to the first and second ring portions 14 and 15 of the pedestal 10, respectively. Due to the step between the first and second ring portions 4 and 15, the two induction coils 46 and 47 also have a step. An induction area is formed in the vicinity of the two induction coils 46, 47, and the induction area of the larger induction range formed via the two induction coils 46, 47 mounted at two different heights makes it extremely A good detection effect is provided, and the lifting effect of the flip cover 30 can be satisfied even if the user does not approach the trash can cover. In addition, by installing the two induction coils 46 and 47 on the trash box cover, static induction can be received at all angles and the flip cover 30 can be automatically lifted. The present invention has a large guidance range, there is no blind spot in the detection area, and the user can be detected just by approaching the trash can cover, so that the flip cover 30 can be raised automatically.

Please refer to FIG. When the user approaches the trash can cover to put in the trash, the detection area where the magnetic field is balanced is subjected to electrostatic interference, and the signal is transferred to the control board 42. The control board 42 drives the actuator 44. The rotation of the interlocking device 45 is interlocked. The interlocking device 45 further starts to rotate the flip cover 30 in conjunction with it. When the interlocking device 45 is rotated, the elasticity of the elastic member 33 attached between the flip cover 30 and the pedestal 10 is released, and the flip cover 30 is pulled up with respect to the pedestal 10 and the cover body 20. It is done. With the assistance of the elastic member 33, the interlocking shaft 451 of the interlocking device 45 is rotated. The elastic member 33 eliminates the need for the actuator 44 to output a large torque, reduces the rotational load on the actuator 44, maintains a longer service life of the actuator 44, and allows the interlock device 45 to rotate with a large torque. There is no fear of causing a tooth loss accident. When the flip cover 30 is pulled up, the first pivotal ear 32 is also pivoted and is locked to the position fixing portion 17 of the pedestal 10 by the second locking portion 323. The effect of position fixing is realized by restricting further rotation.

The control board 42 can set the time when the user puts the dust into the openings 11 and 21 of the trash box cover, that is, the lifting and holding time of the flip cover 30. After a set time, the actuator 44 can drive the interlocking device 45 to rotate and close the flip cover 30.
