Description

Technical Field

[0001] The invention relates to a medical waste cabinet and belongs to the field of medical instruments. Background Art

[0002] Medical waste cabinets are special equipment used by hospitals and other medical institutions to store medical waste. Due to the particularity of medical waste, medical institutions have continuously increased their control requirements for medical waste cabinets. At present, the functional requirements for medical waste cabinets are: it must be easy to put away, and the opening of the cabinet must be able to automatically close after putting away. After closing the cover, it is best to sterilize the medical waste to prevent the public from coming into contact with the medical waste and prevent secondary infection of germs.

[0003] However, the existing opening and closing door control methods of the medical waste cabinet delivery port are mainly manual structure and pedal structure. The existing opening and closing door structures of the medical waste cabinet delivery port are mostly whole-plate flip structure or sliding cover structure. The whole-plate flip structure has a large flip space, and the sliding cover structure is traditional and occupies a large space during use. Opening the flip cover by hand is not only difficult to operate, but also there is a risk of cross-infection of bacteria and viruses by the thrower. Even if a pedal-type opening mechanism is used, there are still many defects. The defects of the opening and closing structure of the delivery port of the existing medical waste cabinet are analyzed as follows:

[0004] (1) Medical staff usually hold the garbage in their hands when putting it out, and manual opening and closing is difficult and difficult to operate;

[0005] (2) Manual opening and closing can easily cause cross infection among medical staff, posing a great safety risk;

[0006] (3) The opening and closing door is a whole-plate flip structure or a sliding cover structure. The whole-plate flip structure has a large flip space. Even if a foot-operated opening mechanism is used, the impact force when it falls back is very large, which can easily force the airflow containing bacteria to flow to the face of the person who puts the medicine, easily causing secondary cross-infection to the person who puts the medicine, and easily causing damage to the cover. The sliding cover structure not only has problems with the placement of the cover, but also increases the workload and time of the person who puts the medicine.

[0007] In summary, the current medical waste cabinets cannot meet the requirements of medical institutions for the placement, temporary storage and sterilization of medical waste. Summary of the invention

[0008] The purpose of the present invention is to provide a multifunctional medical waste collection cabinet, which has a foot-controlled start-up port, a timed closing port, ultraviolet sterilization after the port is closed, and a hand-pinch prevention function during the closing process of the port.

The driven pulley is connected to the driving pulley through a synchronous belt. Both sides of the original sliding door plate are connected to the synchronous belt on the same side through a connector. The long side of the original sliding door plate is parallel to the synchronous drive shaft. An overlapping structure is provided between the original sliding door plate and the driven sliding door plate, and between the driven sliding door plates. Parallel guide grooves corresponding to the number of sliding door plates are provided on the inner sides of the left guide rail seat and the right guide rail seat. The original sliding door plate and the driven sliding door plate are respectively inserted in the corresponding guide rail grooves. The foot-controlled switch is installed on the foot strip board of the open garbage cabinet. The delayed double switch, the controller, the ultraviolet sterilization lamp, and the anti-pinch sensing switch are all installed on the cover seat body. The ultraviolet sterilization lamp is installed on the cover seat body or on the back of the sliding door. The foot-controlled switch, the delayed double switch, the ultraviolet sterilization lamp and the anti-pinch sensing switch are all electrically connected to the controller.

[0010] Furthermore, the driven sliding door plate includes a transition sliding door plate and a terminal sliding door plate.

[0011] Furthermore, the overlapping structure between the active sliding door plate and the driven sliding door plate is as follows: at least two active convex bodies are provided at intervals on the back side of the active sliding door plate, at least two driven convex bodies are provided at intervals on the front side of the transition sliding door plate, and at least two driven convex bodies are provided at intervals on the back side of the transition sliding door plate, at least two driven convex bodies are provided at intervals on the front side of the terminal sliding door plate, the active convex bodies are installed in the concave sliding grooves provided on the transition sliding door plate, and the driven convex bodies on the transition sliding door plate are installed in the concave sliding grooves of the terminal sliding door plate.

[0012] Furthermore, two active convex bodies are provided at intervals on the back of the original sliding door plate, two driven convex bodies are provided at intervals on the back of the transition sliding door plate, and concave sliding grooves corresponding to the driven convex bodies are provided at intervals on the front of the terminal sliding door plate.

[0013] Furthermore, the length of the inwardly concave sliding groove corresponds to the stroke of the sliding door plate.

[0014] Furthermore, the ultraviolet sterilization lamp is installed on the back side of the left and right sides of the cover body 1.

[0018] The working process is as follows:

[0019] When medical staff need to put out medical waste, they touch the foot-operated switch installed on the foot strip board of the open waste cabinet with their feet, so that the motor is energized and rotates forward, and the driving gear installed on the motor output shaft drives the driven gear to rotate. At this time, the synchronous drive shaft rotates in the same direction as the driven gear, thereby synchronously driving the two synchronous belts to move backward. Since the synchronous belt is fixedly connected to the original sliding door plate through a connector, the original sliding door plate moves backward horizontally, so that the original sliding door plate drives the driven sliding door plate to move horizontally and shrink section by section, so that the delivery port is gradually opened. When the original sliding door plate When the terminal sliding door panel and all the driven sliding door panels have reached the open limit position of the garbage delivery port, the terminal sliding door panel touches the delayed double switch installed on the rear side, causing the motor to lose power in the forward direction. After a preset time, the delayed double switch provides reverse current to the motor, causing the motor to rotate in the opposite direction, thereby driving the original sliding door panel and all the driven sliding door panels to move back in the opposite direction and unfold section by section. When the garbage delivery port is completely closed, the controller turns on the ultraviolet sterilization lamp to emit light, and relies on ultraviolet rays to sterilize and disinfect the garbage. The light will automatically turn off after the preset sterilization time and return to the original starting state.

[0020] When the delivery port is in an open state, if someone puts their hand into the delivery port or someone holds their hand on the frame around the delivery port, the anti-pinch sensor switch will be activated. The anti-pinch sensor switch will cut off the power to the motor and interrupt the movement of all sliding door panels, thereby effectively preventing accidents of pinching hands during the opening and closing process of the sliding door panels.

[0021] This multifunctional medical waste cabinet has the functions of foot-operated start, automatic timed closing of the delivery port, automatic UV sterilization and finger-pinch prevention in the closed state, which fully meets the functional setting requirements of medical institutions for medical waste cabinets.

The driven gear 8 is installed on the synchronous drive shaft 6, and driving pulleys 9 are installed at both ends of the synchronous drive shaft 6. Driven wheel seats 11 corresponding to the driving pulleys 9 are installed on the opposite sides of the synchronous drive shaft 6. A driven pulley is installed on the driven wheel seat 11. The driven pulley is connected to the driving pulley 9 through a synchronous belt 10. The two sides of the original sliding door plate 12 are connected to the synchronous belt 10 on the same side through connectors 13. The long side of the original sliding door plate 12 is parallel to the synchronous drive shaft 6. An overlap structure is provided between the original sliding door plate 12 and the driven sliding door plate 14, and between the driven sliding door plates. In this example, there are two driven sliding door plates 14, the first one is a transition sliding door The first embodiment is a terminal sliding door plate 14B, wherein two active convex bodies 121 are provided at intervals on the back of the original sliding door plate 12, and concave sliding grooves 141 corresponding to the active convex bodies 121 are provided at intervals on the front of the transition sliding door plate 14A, and two driven convex bodies 142 are provided at intervals on the back of the transition sliding door plate 14A, and concave sliding grooves 141 corresponding to the driven convex bodies 142 are provided at intervals on the front of the terminal sliding door plate 14B, and the active convex bodies 121 are installed in the concave sliding grooves 141 provided on the transition sliding door plate 14A, and the driven convex bodies 142 on the transition sliding door plate 14A are installed in the concave sliding grooves 141 of the terminal sliding door plate 14B, and the inner The distance between the two ends of the concave sliding groove 141 is the stroke of the corresponding sliding door plate; three parallel guide grooves are provided on the inner sides of the left guide rail seat 2 and the right guide rail seat 3, and the prime sliding door plate 12, the transition sliding door plate 14A and the terminal sliding door plate 14B are respectively inserted in the corresponding guide rail grooves, and the foot-controlled switch 15 is installed on the foot line board of the open garbage cabinet.

[0034] The working process is as follows:

[0035] See also Figure 1-Figure 5 , i.e., the control circuit schematic diagram of the medical waste cabinet. When the medical staff needs to put in the medical waste, they touch the foot-controlled switch 15 with their feet, so that the motor 4 is energized and rotates forward, and the driving gear 7 installed on the motor output shaft drives the driven gear 8 to rotate. At this time, the synchronous drive shaft 6 rotates in the same direction as the driven gear 8, thereby synchronously driving the two synchronous belts 10 to move backward. Since the synchronous belt 10 is fixedly connected to the original moving door plate 12 through the connector 13, the original moving door plate 12 moves backward horizontally, so that the original moving door plate drives the driven moving door plate 14 to move horizontally and condense section by section, so that the delivery port is gradually opened. When the original moving door plate 1 2 and all the driven sliding door panels 14 reach the open limit position of the delivery port, the terminal sliding door panel 14B touches the delayed double switch 16 installed on the rear side, causing the motor 4 to rotate forward and lose power. After a preset time, the delayed double switch 16 provides reverse current to the motor 4, causing the motor 4 to rotate in the opposite direction, thereby driving the driving sliding door panel 12 and all the driven sliding door panels 14 to move back and unfold section by section. When the garbage delivery port is completely closed, the controller 17 turns on the ultraviolet sterilization lamp 18 to emit light, and sterilizes the garbage with ultraviolet rays. After the predetermined time of sterilization, the lamp automatically turns off and returns to the original starting state. When the delivery port is in an open state, if someone puts his hand into the delivery port or someone holds his hand on the frame around the delivery port, the anti-pinch sensor switch 19 will be activated, and the anti-pinch sensor switch 19 will cause the motor 4 to lose power, interrupting the unfolding and movement of all sliding door panels, thereby effectively preventing the hand-pinching accident during the unfolding and closing process of the sliding door panels.

[0036] This multifunctional medical waste cabinet has the functions of foot-operated start, automatic timed closing of the delivery port, automatic UV sterilization and finger-pinch prevention in the closed state, which fully meets the functional setting requirements of medical institutions for medical waste cabinets.
