Trash and garbage collecting apparatus by using bag

Abstract

The present disclosure includes a separating device in which trash, garbage, and air flow through a suction port. A vacuum suction device is provided at the outlet side of the separating device and generates a suction force so that trash, garbage, and air can be sucked through the suction port. Additionally, a passage portion connects the separating device and the vacuum suction device to each other. Further, a collection container is provided on the lower portion of the separating device, and a collection bag accommodates the trash. A bag fixing means is provided to fix the upper end of the collection bag, and a suction passage in communication with the inner upper portion of the collection container and the inner lower portion of the passage portion sucks in the air included in a flow space between the collection bag and the collection container.

         16 . A trash and garbage collecting apparatus using a bag, comprising:
 a suction port through which trash, garbage, and air are sucked;   a separating device in which trash and garbage are separated in communication with the suction port;   a vacuum suction device provided at an outlet side of the separating device and generating a suction force so that trash, garbage, and air are sucked through the suction port and the separating device;   a passage portion of which a first portion and a second portion communicate respectively with the separating device and the vacuum suction device to connect the separating device and the vacuum suction device to each other;   a collection container provided at a lower portion of the separating device;   a collection bag provided in the collection container and accommodating trash therein; and   a suction passage of which a lower end and an upper end communicate respectively with an inner upper portion of the collection container and an inner lower portion of the passage portion to suck air included in a flow space between the collection bag and the collection container,
 wherein the flow space is provided between the collection bag and the collection container, and is a space where air flows, and wherein a pressure drop occurs in air passing through the separating device, and a suction pressure (P 1 ) is formed lower than an internal pressure (P 2 ) by a pressure drop value (ΔP), 
 the suction passage has an upper end and a lower end respectively communicating with the collection container and the passage portion, and a spatial pressure (P 3 ) is formed equal to the suction pressure (P 1 ), 
 the spatial pressure (P 3 ) is formed lower than the internal pressure (P 2 ) by the pressure drop value (ΔP), and 
 the collection bag has a shape inflated toward an inner circumferential surface of the collection container by air having the internal pressure (P 2 ), 
 wherein the suction pressure (P 1 ) is pressure of air included in the passage portion, 
 the internal pressure (P 2 ) is pressure of air in the collection bag, and 
 the spatial pressure (P 3 ) is pressure of air in the flow space between the collection bag and the collection container. 
   
     
     
         17 . The trash and garbage collecting apparatus using a bag of  claim 16 , wherein the separating device comprises:
 a body part;   a separating container provided in the body part and accommodating garbage and air from the suction port; and   a separating plate provided at a lower portion of the separating container and separating the separating container from the collection container,   a nozzle provided at one portion of a lower surface of the separating plate, communicating with the separating container and the collection container, and allowing trash and garbage passing through the separating container to be transferred; and   a nozzle cap fitted over and coupled to an outer circumferential surface of the nozzle, and provided to gather and attach an upper portion of the collection bag,   wherein the upper portion of the collection bag is securely fitted between an outer circumferential surface of the nozzle and an inner circumferential surface of the nozzle cap, and the separating device is coupled to the collection container while a central portion and a lower portion of the collection bag are disposed in the collection container.   
     
     
         18 . The trash and garbage collecting apparatus using a bag of  claim 16 , wherein the separating device comprises:
 a conical basket provided at an inner upper portion of a separating container and provided for air sucked from the separating container to flow,   wherein the conical basket has a conical form of which a diameter is reduced in a direction from an upper portion to a lower portion, and   has a plurality of through holes formed through an outer circumferential surface to allow air sucked by the vacuum suction device to pass therethrough.   
     
     
         19 . The trash and garbage collecting apparatus using a bag of  claim 16 , wherein the separating device comprises:
 a second cylindrical basket which communicates with the passage portion and the separating container, has a cylindrical shape with an open upper portion, and allows air sucked from the separating container to flow therethrough.   
     
     
         20 . The trash and garbage collecting apparatus using a bag of  claim 17 , wherein the separating container comprises
 a spiral guide vein on an inner circumferential surface thereof to allow the trash passing through the suction port to be transferred toward the collection container.   
     
     
         21 . The trash and garbage collecting apparatus using a bag of  claim 17 , wherein the separating container comprises
 an inclined part formed on an inner circumferential surface thereof, and the inclined part allowing trash accommodated spirally in the separating container to be transferred toward a nozzle.   
     
     
         22 . The trash and garbage collecting apparatus using a bag of  claim 16 , wherein the separating device comprises:
 a body part; and   a separating part provided in the body part, wherein the bag fixing means is a nozzle ring coupled to a lower portion of an outer circumferential surface of the separating part so as to gather and attach an upper portion of the collection bag in a one-touch manner.   
     
     
         23 . The trash and garbage collecting apparatus using a bag of  claim 16 , wherein the separating device comprises:
 a first cylindrical basket which communicates with the passage portion and the separating container, has a cylindrical shape with an open upper portion, and allows air sucked from the separating container to flow therethrough,   wherein the first cylindrical basket has a plurality of through holes which is formed through an outer circumferential surface thereof and allows air sucked by the vacuum suction device to pass therethrough.
