Waste sealing structure for waste collection box

Abstract

The present invention relates to a structure for preventing poor sealing of waste collection boxes, which is a type for sealing edges while moving plastic wrap closely in a stacked front and rear direction of waste. The spur gear of a first gear shaft is formed in a shape in which the tooth tip circle coincides with the outer diameter of the gear body, and the spur gear of a second gear shaft that meshes with the spur gear of the first gear shaft is formed in a shape in which the tooth root circle coincides with the outer diameter of the gear body and the tooth tip circle protrudes, so that they mesh with each other and form a groove on the outer diameter section separated from the gear part. An O-ring is inserted in this groove to press the plastic wrap closely and add a sealing part due to the pressing action of the two O-rings, and the meshing part of the gear is sealed so that it cannot be easily torn. This prevents the leakage of bad odors and menstrual blood due to the tearing of the plastic wrap as in the conventional case, and is useful for hygienic use of the waste collection box and future waste collection management.

Description

[Technical field]

[0001] The present invention relates to a structure for preventing poor sealing of waste in a waste collection box, and more particularly, to a structure for preventing poor sealing of waste in a waste collection box, which not only prevents the sealed portion of the wrapper from being torn and solves the problem of foul odors leaking when the edge portion of a wrapper roll with good adhesion is sealed by engaging with a pair of gears, but also further strengthens the sealing force to ensure safe packaging of waste. [Background technology]

[0002] In general, public restrooms at highway rest areas, schools, hospitals, and other institutions have separate restrooms for men and women, and toilet booths (decrepit booths) are provided with trash cans for throwing away used toilet paper, paper dispensers, shelves, etc., for convenience.

[0003] Recently, the toilet paper has been revised so that it can be thrown directly into the toilet after use and then flushed down the toilet, and trash cans have been eliminated in accordance with the Public Toilet Law Enforcement Order, which came into effect on January 1, 2018.

[0004] Typically, in order to properly dispose of and collect sanitary napkins after use by women, women-only public restrooms are provided with sanitary product collection boxes (hereinafter referred to as sanitary napkin collection boxes) for the collection of sanitary napkins only.

[0005] Existing sanitary napkin collection boxes and related prior art mostly rely on boxes to collect sanitary napkins after use, and such collection boxes do not solve the fundamental problem of bad odors (smell leakage). In particular, secondary bad odors are generated when toilet maintenance staff open the collection boxes and collect the sanitary napkins collected in the collection boxes. This not only causes air pollution due to the collection of used sanitary napkins, but also attracts pests, and the sanitary aspects of public toilets used by an unspecified number of people are constantly being pointed out, making it difficult to maintain a comfortable toilet interior.

[0006] Meanwhile, in addition to sanitary napkins, waste from hospitals (such as cotton, gauze, bandages, dressings, disposable gloves, masks, etc. that are discarded after wounds are treated) is treated separately because it has a chemical smell and is infectious.

[0007] However, waste disposal as mentioned above is often not done on a case-by-case basis, and there is a risk of secondary infection as well as the smell of chemicals, so hospitals should be more careful with disinfection. In reality, waste is disposed of in special waste bins or collected in one place for disposal, which leads to air pollution and infection.

[0008] Looking at the prior art in light of the above points, Korean Patent Publication No. 10-2213504 (Name: Sanitary Napkin Collection Box, Registration Date: February 2, 2021, hereinafter referred to as the "Patent Document") is disclosed.

[0009] The sanitary napkin collection box in the patent document has a lock door at the front for collecting used sanitary napkins, a rectangular body having a partition with a passage for used sanitary napkins formed on the inside of the upper part, and a horizontal insertion opening for inserting used sanitary napkins at the center of the upper part, the upper and side faces of which are exposed, and an upper cover having transparent wrap guide pieces that become narrower toward the bottom and are attached vertically downward on both sides of the lower part of the insertion opening, and a pair of upper covers fixed to correspond to both sides of the upper part of the body. a first support base having shaft guide grooves on both sides, parallel support portions formed at an upper portion between the shaft guide grooves and a sensor support portion formed in the middle, and a shaft support hole and a fixing hole for fixing to the main body formed at a lower portion of the sensor support portion; a second support base having a bottom portion formed with a through hole that corresponds to the passage for a used sanitary napkin at an upper portion of the partition wall of the main body and leads to a lower portion of the main body, and side portions having shaft through holes on both sides of the bottom portion, the bottom surface of the bottom portion is seated and fixed to the upper surface of the partition wall of the main body, and both side portions are disposed at an interval between the first support bases; a rotating shaft having both ends rollably supported in the shaft guide groove of the first support stand, first wrap and second wrap in roll form for wrapping and sealing a used sanitary napkin that is inserted by being attached to the rotating shaft; a roller shaft having both ends rotatably installed in the shaft support part of the first support stand and guiding the wrap from the first wrap and the second wrap to the inside lower part of the upper cover through the opening of the insertion port on the upper cover side; a light emitting unit that is fixedly installed in the sensor support part of the first support stand and detects a used sanitary napkin, and a light emitting unit facing the light emitting unit. the light receiving unit is fixed to a sensor support part of a first support stand that matches the light receiving unit and detects the presence or absence of light irradiated from the light emitting unit; a pair of first and second gear shafts having spur gears fixed to both sides of an axle and a tube-type cushioning material installed between the spur gears and installed so that both ends roll on the second support stand; a passive gear connected to the axle of the first gear shaft that passes through the second support stand; a driving gear installed so as to be rotatable on one side of the first support stand on which the passive gear is installed; and a driving motor installed on the second support stand to rotate the driving gear.

[0010] The sanitary napkin collection box 1 as described above has a structure that detects the insertion of used sanitary napkins, operates the driving motor M, and continuously transfers the first wrapper roll W1 and the second wrapper roll W2 mounted on the support stand 2 side to seal waste P such as used sanitary napkins inserted. By collecting used sanitary napkins inside the main body, it solves the most problematic issues of contamination and bad odors with used sanitary napkins and also allows for a clean, sealed and packaged collection box.

[0011] However, as described above, when the wrap rolls W1, W2 are supplied and meshed with each other, and the cushion material 30 is pressed tightly against the sanitary napkins to wrap them after use, and the spur gears 12, 22 of the first gear shaft 10 and the second gear shaft 20 are rotated by meshing with the drive gear G1 and the passive gear G2 on the drive motor M side, the ends where the spur gears mesh with each other cause poor sealing of the wrap roll at the boundary with the cushion material 30, as shown in the accompanying Figures 1 and 2.

[0012] That is, when a used sanitary napkin is inserted and passes between the cushioning materials of the first and second gear shafts, in the case of a thickly folded sanitary napkin or a large-volume baby diaper, the wrap is pulled by the large volume of waste at the spur gear portion where the first and second wraps are in close contact with each other, and the wrap is torn at the edge of the spur gear.

[0013] Typically, the spur gear applied to such collection boxes is an injection molded product made of a plastic material that is easy to produce and is made of a harder material than the original wrap. Due to the nature of the wrap, it is an easy part to seal the edges by making them stick together. However, when the volume of waste inputted becomes large as described above, this can cause the original wrap to be damaged as described above.

[0014] As waste P, used sanitary napkins are wrapped and gradually pile up in the collection box 1, but there is a problem in that the wrap roll breaks due to the tensile force generated at the edge of the spur gear where the wrap roll engages with the spur gear, as shown in part "A" in FIG. 3.

[0015] The torn parts cause the smell of waste or menstrual blood to leak out, contaminating the collection box. This causes odors in the interior space of the toilet booth, and when the collection box is opened to collect used sanitary napkins, workers smell an unclean odor during the process of collecting them, which creates problems such as the need to clean or disinfect the contaminated parts of the collection box.

[0016] Prior art documents in the technical field to which the present invention pertains include the above-mentioned Korean Patent Publication No. 10-2213504. Summary of the Invention [Problem to be solved by the invention]

[0017] The present invention has been invented to solve the above-mentioned problems of the related art, and its object is to provide a structure for preventing poor sealing of waste in a waste collection box, which not only prevents the sealed portion of the wrapper from breaking and solves the problem of foul odors leaking when the edge portion of the wrapper roll, which has good adhesion, is sealed by engaging a pair of gears, but also strengthens the sealing force to ensure safe packaging of waste. [Means for solving the problem]

[0018] According to the present invention for achieving the above object, a waste wrap roll is provided in a form in which both ends can rotate on an internal support of a collection box through an input port of the collection box, and when waste is input, two wrap rolls are supplied in a combined form with the waste sandwiched therebetween. As the wrap roll passes between a first gear shaft and a second gear shaft having spur gears on both sides, the spur gears mesh with each other and the cushioning material on the first and second gear shafts is pressed tightly against each other to seal the ends of the wrap roll. The spur gears on the first and second gear shafts are gear bodies that are partitioned into a gear portion and an outer diameter portion, The spur gear of the first gear shaft is formed so that its tip circle coincides with the outer diameter portion of the gear body, and the spur gear of the second gear shaft which meshes with the spur gear of the first gear shaft is formed so that its root circle coincides with the outer diameter portion of the gear body and its tip circle protrudes. A groove is formed on the outer diameter portion of the gear body of the spur gear, and an O-ring is inserted in the groove to tightly fit the lap web. One end side of the outer diameter portion of the gear body is formed to be inclined so that the lap web can pass through the groove without any interference at a right angle to the lap web.

[0019] According to the present invention, the gear body on which the spur gear of the first gear shaft is formed and the groove of the gear body on which the spur gear of the second gear shaft is formed are formed to be offset from each other, so that the pressurized sealing of the wrap raw material through the O-ring is performed at two points.

[0020] According to the present invention, one or more pressure protrusions are formed at intervals on an outer diameter portion of a spur gear of the first gear shaft, and a seating groove having a width and depth is formed on an outer diameter portion of a gear body on which the spur gear of the second gear shaft is formed, and a band-shaped bundling that contacts the pressure protrusions is inserted into the seating groove to perform pressure sealing of the wrap raw material.

[0021] According to the present invention, the gear portion is formed to a depth of 1.5 to 2.5 mm from the tip circle to the root circle, and meshing of the spur gear is performed. Effect of the Invention

[0022] The waste collection box structure according to the present invention prevents waste from being easily sealed. In this type, waste is stacked on the front and back, and when the wrap roll is moved closely to seal the periphery, the spur gear of the first gear shaft is formed in a shape in which the tooth tip circle coincides with the outer diameter of the gear body, and the spur gear of the second gear shaft which meshes with the spur gear of the first gear shaft is formed in a shape in which the tooth root circle coincides with the outer diameter of the gear body and the tooth tip circle protrudes, so that they mesh with each other and form a groove on the outer diameter section separated from the gear section. An O-ring is inserted in this groove to press the wrap roll closely and add a sealing part due to the pressing action of the two O-rings, and the meshing part of the gear is sealed so that it does not easily break, thereby preventing the leakage of bad odors and menstrual blood due to the breakage of the wrap roll as in the conventional case, and providing useful advantages in hygienic use of the waste collection box and future waste collection management.

[0024] The present invention will now be described in more detail with reference to the accompanying drawings.

[0025] Prior to this, the terms and words used in this specification and claims should not be interpreted limited to their ordinary or dictionary meanings, but should be interpreted in a way that corresponds to the technical idea of ​​the present invention, based on the principle that an inventor can appropriately define the concept of a term in order to best describe his / her invention.

[0026] Therefore, it should be understood that the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent the entire technical idea of ​​the present invention, and therefore there may be various equivalents and modifications that can be substituted for them at the time of this application.

[0027] The waste sealing structure of the present invention will be described below with reference to the accompanying Figs. 4 to 10.

[0028] The wrap rolls are provided so that both ends can rotate on the internal support stand 2 of the collection box through an inlet on the collection box side, and when waste P is input, two wrap rolls W1, W2 are supplied in a form in which they are joined together with the waste sandwiched between them. As the wrap rolls pass between the first gear shaft 10 and the second gear shaft 20, which are provided with spur gears 12, 22 on both sides, the spur gears 14, 14 mesh with each other and the cushioning material 30 on the first gear shaft and the second gear shaft is tightly pressed to seal the edges of the wrap rolls. The spur gears 12, 22 on the first gear shaft 10 and the second gear shaft 20 each consist of a gear body 11, 21 that is partitioned into a gear portion 12a, 22a and an outer diameter portion 12b, 22b.

[0029] The spur gear is made of synthetic resin, not metal, and is made of resin by pressing the wrap roll tightly rather than the parts that need to transmit the power of the gear. In order to improve the sealing effect by pressing the wrap roll tightly rather than the parts that need to transmit the power of the gear, the gear teeth are densely formed with at least 80 to 150 teeth from the base circle.

[0030] The spur gear 12 of the first gear shaft 10 is formed in such a way that its addendum circle coincides with the outer diameter portion 12a of the gear body 11, and the spur gear 22 of the second gear shaft 20 which meshes with the spur gear 12 of the first gear shaft 10 is formed in such a way that its tooth circle coincides with the outer diameter portion 22a of the gear body 21 and its addendum circle protrudes.

[0031] In other words, the meshing rotation of the spur gear of the first gear shaft and the spur gear of the second gear shaft are arranged so that their outer diameter portions are in close contact with each other, and the O-ring inserted in the groove described later allows the wrap base to be pressed and compressed with a minimum gap.

[0032] Grooves 12-1, 22-1 are formed in the outer diameter portions 12b, 22b of the gear bodies 11, 21 of the spur gears 12, 22, and O-rings 40 are interposed in the grooves 12-1, 22-1 to tightly contact the lap webs W1, W2 which are supplied at angles narrowing on the front and rear sides, respectively.

[0033] One end side of the outer diameter parts 12b, 22b of the gear bodies 11, 21 is formed to be inclined, and configured so that the wrap webs W1, W2 can pass through the recessed grooves 12-1, 22-1 without interference at right angles to the wrap webs W1, W2.

[0034] The grooves 12-1, 22-1 of the gear body 11 on which the spur gear 12 of the first gear shaft 10 is formed and the gear body 22 on which the spur gear 22 of the second gear shaft 20 is formed, and the O-ring 40 elastically fitted in the grooves are formed in a mutually offset shape as shown in attached FIG. 8, so that the wrap raw fabrics W1, W2 are pressurized and sealed at two points through the O-ring 40.

[0035] Alternatively, as shown in the accompanying FIG. 7, the grooves 12-1, 22-1 and the O-rings 40 formed on the outer diameter portions 12b, 22b of the spur gears 12, 22 are formed to face each other, so that the wrap sheet can be pressurized and sealed even when the O-rings 40 are in maximum contact with each other.

[0036] The O-ring 40 is made of a urethane rubber material and has a predetermined cushioning and elasticity to tightly seal the wrap webs W1 and W2.

[0037] Meanwhile, as one embodiment of the present invention, as shown in the accompanying FIG. 9, one or more pressure protrusions 12b-2 are formed at intervals on the outer diameter portion 12b of the spur gear 12 of the first gear shaft 10, and a seating groove 22b-2 having a width and depth is formed on the outer diameter portion 22b of the gear body 21 on which the spur gear 22 of the second gear shaft 20 is formed, and a band-shaped band ring 23 that contacts the pressure protrusions 12b-2 is inserted into the seating groove 22b-2 to perform pressure sealing of the wrap raw material.

[0038] On the other hand, it is preferable that the depth from the tip circle to the bottom circle of the gear portions 12a, 22a is 1.5 to 2.5 mm so that the spur gears 12, 22 mesh with each other.

[0039] For reference, the wrap roll is often used for packaging food, and sticks to non-electrically charged objects and electrically heated objects (non-conductors) due to the property of static electricity (static electricity generated on the surface when the wrap roll is unwrapped from the roll). In addition, since it has elasticity, a force that tries to return to its original shape is generated, and the wrap roll sticks well to the wrap roll while wrapping the sanitary napkin after use, as mentioned above, and is sealed. Here, the wrap roll naturally tightly packs the waste due to the pressure of the cushioning material made of foam sponge material.

[0040] For reference, one of the spur gears of the waste collection box according to the present invention is structured so that power is transmitted by meshing rotation of a driving gear provided on the rotating shaft of a driving motor, and simple operation control is performed through the control unit of the collection box, and detailed description thereof will be omitted below.

[0041] The waste sealing operation of the waste collection box of the present invention constructed as above will be described below.

[0042] Referring to FIG. 2, when waste P such as sanitary napkins is put into the collection box, the waste P is detected, and the detected signal operates the drive motor to rotate the spur gear 12 of the first gear shaft 10, which is installed on the support base 2 so that both ends can rotate, through the drive gear. As the spur gear 22 of the second gear shaft 20 meshes with the spur gear 12 of the first gear shaft 10 and rotates, the wrap rolls W1 and W2 with the waste P placed therebetween move downward, and their edges are pressurized and sealed.

[0043] As described above, the wrap raw rolls W1, W2 are sealed by the cushioning material 30 interposed between the spur gear 12 of the first gear shaft 10 and the spur gear 22 of the second gear shaft 20, which presses against the outside of the wrap raw roll according to the shape of the waste P that has entered, and the edges of the wrap raw rolls W1, W2 are pressurized at two points by the O-rings 40 on the outer diameter portions 12b, 22b of the spur gear 12 of the first gear shaft 10 and the spur gear 22 of the second gear shaft 20. The wrap raw rolls W1, W2 are pressed down by the meshing of the gear portions 12a, 22a, allowing the cushioning material 30 to pass through while sealing three points at both ends of the wrap raw rolls W1, W2 in the direction of travel, based on the waste P.

[0044] In particular, one end of the outer diameter portion of the spur gears 12, 22 is formed to be inclined, and the wrap raw sheets W1, W2 are sealed as described above while forming a naturally opposed oblique angle rather than a right angle with the end of the outer diameter portion 12b, 22b, so that it is possible to prevent the tearing phenomenon that occurs when the wrap raw sheets W1, W2 are pushed by the end of the spur gear due to the meshing of the existing spur gear.

[0045] In addition, the sealing of the wrap rolls W1, W2 according to the present invention is achieved by sealing at two points using two O-rings 40, and the engagement of the gear portions 12a, 22a is separated from the outer diameter portion by being separated from the O-ring 40 provided in the grooves 12-1, 22-1 on the outer diameter portion 12b, 22b, and is sealed by the engagement of the denser number of teeth of the gear portions 12a, 22a. This eliminates the tearing phenomenon that often occurs at the end of the engagement at the right angle of the spur gear as the wrap roll increases with the volume of waste, and achieves stable sealing that prevents the smell of waste from leaking out.

[0046] In particular, the sealing by the gear portions 12a and 22a is such that the spur gear 12 of the first gear shaft 10 is formed in a shape in which the tip circle thereof coincides with the outer diameter portion 12a of the gear body 11, and the spur gear 22 of the second gear shaft 20 which meshes with the spur gear 12 of the first gear shaft 10 is formed in a shape in which the root circle thereof coincides with the outer diameter portion 22a of the gear body 21 and the tip circle thereof is protruded.

[0047] The meshing of these gear portions 12a, 22a is performed with a depth of 1.5 to 2.5 mm from the tip circle to the root circle and with 80 to 150 dense gear teeth, so that the sealing effect is dense and excellent.

[0048] In accordance with the present invention, in conjunction with the meshing of the gear portions 12a, 22a, the O-ring 40 may be provided in the grooves 12-1, 22-1 at the same position as the outer diameter portions 12b, 22b as shown in FIG. 7, thereby sealing the wrap web through elastic pressure contact between the O-rings. Alternatively, as shown in FIG. 8, the O-ring 40 may be provided in the grooves 12-1, 22-1 of the gear body 11 on which the spur gear 12 of the first gear shaft 10 is formed and the gear body 22 on which the spur gear 22 of the second gear shaft 20 is formed, and the O-ring 40 may be disposed in a shifted manner, thereby allowing the wrap webs W1, W2 to be pressurized and sealed at two points through the O-ring 40, thereby enabling more stable sealing.

[0049] Attached FIG. 9 shows another embodiment of the present invention, in which one or more pressure protrusions 12b-1 protrude from the outer diameter portion 12b of the spur gear 12 of the first gear shaft 10, and the outer diameter portion 22b of the gear body 21 on which the spur gear 22 of the second gear shaft 20 is formed has a belt-shaped band ring 23 provided in a seating groove 22b-1 having width and depth, and the wrap raw material W1, W2 is sealed by a structure in which the pressure protrusions 12b-1 press the wrap raw material W1, W2 by clamping it between the band ring 23.

[0050] The band-shaped bundling 23 is made of an elastic urethane rubber material, and the pressing protrusions 12b-1, which are relatively in close contact with the wrap material, rotate while pressing the wrap material, so that the same pressurized sealing effect as described above is achieved.

[0051] As described above, the front of the pressurized and sealed wrap rolls W1 and W2 simultaneously forms two straight pressure sections B and pressure section C formed by the meshing of the gear sections as shown in attached Figure 10, so that the wrap rolls can be sealed in a way that prevents odors, menstrual blood, etc. from leaking out to the edges, unlike conventional gear sealing.

[0052] Therefore, the waste collection box can be used in a more hygienic manner inside a toilet booth or in a hospital treatment room, and the waste can be collected hygienically without odor problems while preventing contamination of the waste collection box during the subsequent waste collection process.

[0053] The structure for preventing poor sealing of the wrap roll of the present invention is a relatively simple structure, but when considering the aspect of sealing and packaging waste without generating unpleasant odors and collecting it, it is a technology that is sufficient to meet the requirements of a waste collection box.

[0054] As described above, the present invention has been described using specific details such as concrete components, limited examples, and drawings. However, this is merely provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above examples. Various modifications and variations are possible from such descriptions by those having ordinary knowledge in the field to which the present invention pertains.

[0055] Therefore, the concept of the present invention should not be limited to the described embodiments, but should be understood to include not only the claims set forth below, but also all things that are equivalent to or have equivalent modifications within the scope of the claims, which are within the scope of the concept of the present invention.
