Description

Mask Crusher {Crusher of Mask}

The present invention relates to a mask shredding machine, and more particularly, to reduce the storage volume of a mask by cutting a mask used by a pair of shredding rolls, and to install a UV lamp on one side of a collection box in which shredded masks are temporarily stored to irradiate with ultraviolet rays. It relates to a mask shredder with improved safety and storage that can safely handle mask debris without fear of infection when emptying the collection box by removing the virus remaining in the mask shredder.

Masks are used to block external contaminants such as fine dust, yellow dust, and viruses from entering the human body through the respiratory system. In particular, in order to be protected from highly contagious viruses such as corona, masks must be changed frequently.

Therefore, a large number of masks discarded after use can be generated per person per day, and in places where a large number of people are concentrated, such as schools and hospitals, the amount of masks discharged is considerable and the volume is also significantly increased.

In addition, since it is unclear whether the mask discarded after use was used by an infected person, it is difficult for a manager who collects garbage or manages the environment to handle it due to concerns about infection, and wild animals are harmed by illegally dumped waste masks. This may occur, or a problem of collecting and recycling waste masks may occur.

In order to solve the above problems, it is important to prevent secondary infection by collecting disposable masks that are discarded after use separately from general garbage so that environmental sanitation workers can more safely handle them, and by crushing them during collection to prevent recycling. In this method of crushing, crushing immediately after collection is also useful in reducing the storage volume.

For this reason, mask shredding can be applied to existing document shredders, but it is not possible to prepare for viruses that may remain in the mask, so there is still an inherent risk of secondary infection by administrators who handle it for management.

Chinese Registered Office No. 21190318 (2020.11.10. Registration; hereinafter referred to as 'Prior Document 1') suggested a document shredder with a built-in sterilization module. Prior Document 1 provides a device that separates the case, installs a document shredder in one space, and provides an air sterilization device in the other space, enabling document shredding and air sterilization to be performed simultaneously using one device. Although the mask can be pulverized by inserting it into the shredder of Prior Document 1, there is no means for sterilizing the cut mask. Of course, in Prior Document 1, an air sterilization device is provided, but it is separated from the shredder and independently purifies the air, and there is no method for sterilizing the inside of the shredder.

Chinese Registered Utility No. 213669713 (registered on July 13, 2021; hereinafter referred to as 'Prior Document 2') suggested a low-noise card shredder. The prior art document 1 makes it possible to check the amount of internal debris through a transparent window, but has no sterilization function for the debris.

Therefore, although the volume of mask debris can be reduced by shredding the mask using an existing document or card shredder, the virus on the mask cannot be sterilized. Since there is an inherent risk of infection, the need for a shredder having a function of breaking and sterilizing the mask itself has emerged.

Chinese registered utility No. 21190318 (2020.11.10. registration): document shredder with built-in sterilization module China Registered Practical No. 213669713 (registered on July 13, 2021): Low-noise card shredder

The main body 20 has a mask inlet 21 for introducing a mask into the upper surface, and an operation button 22 is formed on one side thereof. The operation button 22 may be formed as a power button to supply power before use. Here, the cutting roller can be driven by power supply, but a detection sensor is mounted inside the mask inlet 21 so that the controller 60 turns on power to the cutting roller 30 when it detects that the mask is input into the mask inlet. By supplying and operating, it can be configured in a low power mode in which power is supplied and operated only when necessary.

The cutting roller 30 is located below the mask inlet 21 of the body and crushes the input mask. The cutting roller 30 may use various known shapes, and it is particularly preferable to use a shape capable of pulverizing an iron core located on the bridge of the nose of the mask. It is preferable that the cutting rollers are arranged in a pair, and a pair of cutting rollers may be arranged in two rows, respectively, in order to cut the mask into smaller sizes.

The cutting roller 30 has a gear installed on the shaft to receive power from a motor so as to be shredded while being rotated, and the motor receives power under the control of a control unit to operate.

The collection box 40 is disposed inside the lower part of the main body 20 and is installed to be drawn out to the front or side of the main body. This collection box is a container for collecting and temporarily storing the mask fragments shredded by the cutting roller. Therefore, the collection box 40 forms a transparent window at a portion exposed to the outside of the main body 20 so that the amount of collected mask debris can be easily checked from the outside and the mask debris loaded inside can be quickly emptied and managed.

The UV lamp 50 passes through the cutting roller 30 and radiates UV to the shredded mask material to kill the virus attached to the mask. The UV lamps 50 may be provided at the front and rear of the mask shatter, respectively, so that UV irradiation is performed through the front and rear surfaces.

In addition, since the UV lamp is installed in the space between the lower part of the cutting roller and the upper part of the collection box, UV is irradiated to the upper surface of the mask fragments loaded in the collection box as well as while the mask fragments shredded through the cutting roller are put into the collection box, thereby enabling sterilization. It can be done.

The controller 60 is installed inside the main body 20 to control various operations, and when the operation button 22 is clicked, power is supplied to a motor that drives the cutting roller 30 to operate the transfer roller. , When a detection sensor is installed in the mask inlet, the control unit supplies power to the motor when the detection signal is received by the detection sensor to drive the cutting roller, and supplies power to the motor several seconds after the detection signal of the detection sensor is removed. can be blocked to stop the driving of the cutting roller.

In addition, by supplying power to the UV lamp 50 at the same time as supplying power to the motor, UV irradiation may be performed on the shattered mask.

As shown, in the mask shredding machine according to the present invention, a blower fan 70 is further installed to lower the internal humidity of the collection box 40 loaded with the mask shavings to block the growth of viruses. Since the mask has a large amount of moisture on one side due to breathing, if it is crushed and loaded by the shredder in a state containing moisture, the virus proliferates inside and may cause secondary contamination to the area near the mask shredder.

Therefore, by installing the blowing fan 70 therein, it is possible to quickly dry the moisture of the mask through air circulation and suppress the growth of viruses. Here, a filter unit 72 may be further installed on the air discharge passage 71 in which the blowing fan 70 is installed to filter viruses or foreign substances in the discharged air so that only clean air is discharged.

As shown in FIG. 3B, the filter unit 72 may be formed to have an inclined surface with an upper part protruding and a lower part retracting. If the filter unit 72 is formed at an angle, when the suction force of the blowing fan is removed, lumps such as dust filtered on the surface of the filter unit can be put back into the collection box.

In addition, a humidity sensor 73 may be further installed in the main body 20 so that the blowing fan 70 operates according to a humidity set value. The measurement value of the humidity sensor 73 is transmitted to the control unit 60, and when the humidity is high based on the preset humidity setting value, the control unit supplies power to the blowing fan 70 to drive the blowing fan to discharge the air inside the collection box. It can be made to dry. At this time, since the outside air is introduced through the mask inlet 21, drying can be performed as a whole. In addition, when the measured value of the humidity sensor is less than the set humidity value, the control unit cuts off power provided to the blowing fan to stop the blowing fan.
