[0038] refer to Figure 1 As shown, the first embodiment of the present invention provides a non-contact safe packaging medical waste collection device, including a box body 11, a disinfection system 12, a sealing mechanism 13 and a controller 14.

[0039] A garbage inlet 111 is provided on the upper side wall of the box body 11. Of course, a garbage inlet 111 may also be provided on the top of the box body 11. A shielding plate is provided at the garbage inlet 111. The upper end of the shielding plate is hinged to the box body 11, and the lower end of the shielding plate is a free end.

[0040] The controller 14 is a PLC controller 14, which is arranged inside the box 11. A control panel is arranged on the outer wall of the box 11, and the control panel is connected to the controller 14. Instructions can be issued through the control panel. The chip of the controller 14 can be STM32F103RBT6 or STC12C5608AD.

[0041] A first guide plate 112 is provided inside the box body 11 at the garbage inlet 111 , and the first guide plate 112 extends obliquely downward from the garbage inlet 111 toward the middle of the box body 11 . Garbage thrown in from the garbage inlet 111 will fall on the first guide plate 112 and then slide down along the first guide plate 112 .

[0042] A vibrator 113 may be provided at the bottom of the first guide plate 112 . The vibrator 113 is electrically connected to the controller 14 . Vibration of the vibrator 113 can make the garbage on the first guide plate 112 slide downward more easily, thereby avoiding accumulation on the first guide plate 112 .

[0043] A first sensor 114 is provided inside the box body 11, and the first sensor 114 corresponds to the garbage inlet 111. The first sensor 114 is used to sense whether there is garbage falling on the first guide plate 112. The first sensor 114 is connected to the controller 14 through a signal line, and the first sensor 114 can transmit the sensed information to the controller 14 for processing.

[0044] The disinfection system 12 includes a disinfectant storage container 121 and a spray head 122 .

[0045] The disinfectant storage container 121 is arranged inside the box 11, and the disinfectant storage container 121 can also be arranged outside the box 11. The nozzle 122 is supported on the inner wall of the box 11 and corresponds to the first guide plate 112. The disinfectant storage container 121 and the nozzle 122 are connected through a pipeline, and a water pump 123 is arranged on the pipeline, and the water pump 123 is electrically connected to the controller 14. When the sensor senses that garbage is thrown in from the garbage input port 111, the controller 14 will control the water pump 123 to work, extract the disinfectant in the disinfectant storage container 121 and transport it to the nozzle 122, and then spray it from the nozzle 122 onto the garbage on the first guide plate 112, so as to achieve the disinfection of the garbage. A solenoid valve is arranged in the nozzle 122, and the solenoid valve is electrically connected to the controller 14, so that the nozzle 122 can be controlled separately to spray the disinfectant.

[0046] Of course, an ultraviolet lamp 115 may also be provided in the box 11, the ultraviolet lamp 115 corresponds to the first guide plate 112, the ultraviolet lamp 115 is connected to the controller 14, and the ultraviolet lamp 115 can also perform ultraviolet disinfection on the garbage on the first guide plate 112. By disinfecting and sterilizing the garbage with disinfectant and ultraviolet rays at the same time, the viruses carried on the garbage can be greatly reduced.

[0047] A collecting trough 15 is provided in the box body 11, and a garbage bag is placed in the collecting trough 15. A box door 116 is provided at a position corresponding to the collecting trough 15 on the front side wall of the box body 11. The bottom of the collecting trough 15 is slidably matched with the inner bottom surface of the box body 11. The collecting trough 15 can be pulled out from the box door 116 by opening the box door 116. When the collecting trough 15 is inside the box body 11, the collecting trough 15 is located directly below the discharge end of the first guide plate 112, so that the sterilized garbage on the first guide plate 112 will flow down along the first guide plate 112 and fall into the garbage bag in the collecting trough 15.

[0048] The sealing mechanism 13 is disposed at the upper end of the collecting tank 15 , and is used to seal the garbage bag in the collecting tank 15 .

[0049] The sealing mechanism 13 includes a first sealing strip 131 , a second sealing strip 132 , a latch assembly 133 and a sealing spring 134 .

[0050] The first seal 131 is fixedly disposed at the upper end of the collecting tank 15 and close to the front side of the collecting tank 15 , and the second seal 132 is slidably disposed at the upper end of the collecting tank 15 . The second seal 132 is parallel to the first seal 131 , and the length of the second seal 132 is greater than the length of the first seal 131 .

[0051] The sealing spring 134 is arranged on the left and right sides of the collecting groove 15, one end of the sealing spring 134 is connected to the outer wall of the collecting groove 15, and the other end of the sealing spring 134 is connected to the end of the second seal 132. Under the action of the contraction elastic force of the sealing spring 134, the second seal 132 can be pulled to slide toward the first seal 131. When the second seal 132 slides to abut against the first seal 131, the mouth of the garbage bag can be sealed under the action of the supporting force of the first seal 131 and the second seal 132. In order to facilitate sealing, the clamping surfaces of the first seal 131 and the second seal 132 can be processed into a serrated structure. Of course, in order to achieve a better sealing effect, a heating element 135 can be provided on the side of the first seal 131 close to the second seal 132 and on the side of the second seal 132 close to the first seal 131. The heating element 135 is connected to the controller 14. In this way, when the second seal 132 abuts against the first seal 131, the controller 14 controls the heating element 135 to generate heat, thereby heat-sealing the mouth of the garbage bag.

[0052] The latch assembly 133 is disposed at the upper end of the inner rear side wall of the collection trough 15 , and is used to latch the second seal 132 , so that the second seal 132 is located on the opposite side of the first seal 131 , which facilitates the garbage bag in the collection trough 15 to pack garbage.

[0053] refer to Figure 2As shown, the bayonet assembly 133 includes a limit pin 1331, a return spring 1332 and an electromagnet 1333. A limit slot is provided at the upper end of the rear side wall of the collecting tank 15. The electromagnet 1333 is arranged at the bottom of the limit slot. The electromagnet 1333 is connected to the controller 14. The limit pin 1331 is made of metal. The limit pin 1331 is supported in the limit slot by the return spring 1332 and is located directly above the electromagnet 1333. The bayonet assembly 133 has a first state in which the upper end of the limit pin 1331 extends out of the limit slot under the action of the return spring 1332 when the electromagnet 1333 is not energized, and a second state in which the limit pin 1331 moves downward under the action of the magnetic force so that its upper end retracts into the limit slot when the electromagnet 1333 is energized to generate magnetic force. When the second clamping strip is located at the rear side of the collecting slot 15, the limit pin 1331 is in the first state. At this time, the limit pin 1331 is used to clamp the second seal 132 to prevent the second seal 132 from sliding toward the first seal 131. When the garbage bag needs to be sealed, the electromagnet 1333 is energized, and then the limit pin 1331 is retracted into the limit slot under the action of magnetic force, so that the second seal 132 can slide toward the first seal 131 and clamp the first seal 131 to achieve the sealing operation.

[0054] It should be noted that, in another embodiment, reference Figure 3 and 4 As shown, the latch assembly 133 includes a limit pin 1331, a reset spring 1332 and a toggle pin 1335. A limit slot is provided at the upper end of the rear side wall of the collecting trough 15. The limit pin 1331 is supported in the limit slot by the reset spring 1332. A notch is provided at the rear side wall of the collecting trough 15 at a position corresponding to the limit pin 1331. A pressure plate 1334 is provided on the limit pin 1331. The pressure plate 1334 and the limit pin 1331 form a T-shaped structure. The pressure plate 1334 passes through the notch. The toggle pin 1335 is arranged on the rear side wall of the box body 11 and corresponds to the pressure plate 1334. The toggle pin 1335 slides in cooperation with the box body 11. When the push pin 1335 is not subjected to external force, it is in a free state. At this time, the upper end of the limit pin 1331 extends out of the limit slot under the action of the reset spring 1332 to clamp the second seal 132; when the push pin 1335 is pushed downward, the push pin 1335 presses the pressure plate 1334 downward, and then the limit pin 1331 moves downward, and the upper end of the limit pin 1331 retracts into the limit slot. At this time, the second seal 132 slides toward the first seal 131 under the action of the sealing spring 134, and clamps the first seal 131 to achieve the sealing operation.

[0055] The non-contact safe packaging medical waste collection device further comprises a crushing mechanism 16 .

[0056] refer to Figure 5As shown, the crushing mechanism 16 includes a crushing roller 161 and a second driving mechanism. There are two crushing rollers 161. The two crushing rollers 161 are supported side by side and rotatably in the box body 11 and are located between the first guide plate 112 and the collecting tank 15. A crushing zone is formed between the two crushing rollers 161. The crushing zone is located directly below the discharge end of the first guide plate 112. The garbage sliding off the first guide plate 112 can directly fall into the crushing zone. The second driving mechanism includes a motor 162 and a reducer 163. The motor 162 and the reducer 163 are both supported inside or outside the box body 11. The reducer 163 has two output shafts. The two output shafts of the reducer 163 are respectively connected to one end of the two crushing rollers 161 through a coupling. The output shaft of the motor 162 is connected to the input shaft of the reducer 163. The motor 162 is also electrically connected to the controller 14. In this way, the motor 162 can drive the two crushing rollers 161 to crush the objects in the crushing area, and the crushed materials directly fall into the garbage bag in the collecting trough 15.

[0057] A second guide plate 117 is further provided between the crushing mechanism 16 and the collecting tank 15. The second guide plate 117 is supported on the inner wall of the box body 11. The lower end of the second guide plate 117 extends downwardly at an angle to above the opening end of the collecting tank 15. The second guide plate 117 is provided so that all the crushed garbage falls into the garbage bag. A vibrator 113 may be provided at the bottom of the second guide plate 117. The vibrator 113 is electrically connected to the controller 14. The vibration of the vibrator 113 can make the garbage on the second guide plate 117 slide downward more easily to avoid accumulation on the second guide plate 117.

[0058] A second sensor 17 is also provided inside the box body 11. The second sensor 17 is supported above the collecting trough 15 by a support rod and is located below the second guide plate 117. The second sensor 17 is used to detect the amount of garbage in the garbage bag. The second sensor 17 is connected to the controller 14. The information on the amount of garbage detected by the second sensor 17 can be fed back to the background management terminal through the controller 14, so that people can remotely understand the storage amount in the garbage bag. When the storage amount of garbage reaches a certain amount, it can be collected and processed in time.

[0059] The working principle of the non-contact safe packaging medical waste collection device provided by the embodiment of the present invention is as follows:

[0060] When people throw garbage into the garbage bin from the garbage inlet 111, it will fall onto the first guide plate 112. At the same time, when the first sensor 114 senses that garbage has fallen onto the first guide plate 112, it will feed back a signal to the controller 14. The controller 14 controls the water pump 123 to work, so that the disinfectant in the disinfectant storage container 121 is extracted and sprayed from the nozzle 122, and the disinfectant is sprayed onto the garbage, thereby achieving the disinfection of the garbage and reducing the risk of virus transmission. The disinfected garbage slides along the first guide plate 112 into the crushing mechanism 16 for crushing, and the crushed garbage falls into the garbage bag in the collection tank 15. When a certain amount of garbage is stored in the garbage bag, the latch assembly 133 is controlled to make the limit pin 1331 retract into the limit slot, so that the second seal 132 can slide toward the first seal 131 under the action of the sealing spring 134, and clamp with the first seal 131 to achieve the sealing operation of the garbage bag. Then, the box door 116 is opened, and the collecting trough 15 is pulled out from the box body 11, so that the sealed garbage bag is taken out and replaced with a new garbage bag. During the garbage collection process, the sanitation workers do not have direct contact with the garbage, which greatly reduces the risk of being infected by bacteria and viruses. In addition, during the process of pulling out the collecting trough 15, since the length of the second seal 132 is greater than the length of the first seal 131, the second seal 132 is blocked by the side wall of the box body 11, and the second seal 132 slides backward relative to the collecting trough 15. When sliding over the limit pin 1331, it is stuck by the limit pin 1331, and then it is convenient to replace a new garbage bag. Moreover, when the collecting trough 15 is sent back into the box body 11, the second seal 132 is also at the rear end of the collecting trough 15, which will not affect the collection of garbage. Example 2

[0061] refer to Figure 6 As shown, the second embodiment of the present invention provides a non-contact safe packaging medical waste collection device, which differs from the first embodiment in the sealing mechanism 13. The structure, working principle and technical effects of the remaining parts are the same as those in the first embodiment and will not be elaborated here.

[0062] The sealing mechanism 13 includes a first seal 131, a second seal 132 and a first driving mechanism. The first seal 131 is fixedly arranged at the upper end of the collecting trough 15 and close to the front side of the collecting trough 15. The second seal 132 is slidably arranged at the upper end of the collecting trough 15. The second seal 132 is parallel to the first seal 131. The first driving mechanism is arranged on the left and right sides of the collecting trough 15 and is respectively connected to the two ends of the second seal 132. The first driving mechanism is used to drive the second seal 132 to slide toward or away from the first seal 131. When the second seal 132 abuts against the first seal 131, the garbage bag can be sealed.

[0063] In this embodiment, the first driving mechanism includes an electric push rod 136, one end of the electric push rod 136 is connected to the outer wall of the collecting tank 15, and the other end of the electric push rod 136 is connected to the end of the second seal 132. The electric push rod 136 is also connected to the controller 14, and the extension and retraction of the electric push rod 136 can be controlled by the controller 14. The extension and retraction of the electric push rod 136 can drive the second seal 132 to slide back and forth at the upper end of the collecting tank 15.

[0064] In another embodiment of the sealing mechanism 13, the first driving mechanism includes a hydraulic cylinder and a hydraulic station, one end of the hydraulic cylinder is connected to the outer wall of the collecting tank 15, and the other end of the hydraulic cylinder is connected to the end of the second seal 132.
