[0002] As a commonly used medical waste bin, the pedal-type trash can can keep the trash can in a normally closed state, which can reduce the contact between medical staff and medical waste.

[0003] A common pedal-type trash can includes a barrel body and a barrel cover. The upper side of the barrel body is open, and the barrel cover is hinged on the upper side of the barrel body. A pedal is hinged on the lower side of the barrel body. The hinge axis of the pedal is located in the middle area of ​​the pedal, and the front side of the pedal is exposed on the lower side of the barrel cover. The rear side is hingedly connected to a transmission rod. The upper end of the transmission rod is hinged on the barrel cover, and the hinge axes at both ends of the transmission rod are parallel to the hinge axis of the pedal. Medical staff step on the front side of the pedal with their feet, so that the pedal rotates and drives the transmission rod to move upward. The transmission rod can drive the barrel cover to rotate and move away from the barrel body, thereby realizing the opening of the barrel body, which is convenient for medical staff to throw garbage into the barrel body. After the medical staff releases the pedal, the barrel cover rotates and falls.

[0004] With respect to the above-mentioned related technologies, after the medical staff releases the pedal, the barrel cover rotates and falls under the driving force of gravity. The barrel cover will gradually accelerate during the falling process. When the barrel cover closes the barrel body, it is easy to fan the odor in the barrel body out of the barrel body.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present application embodiment discloses a medical waste bin. Figure 1 and Figure 2 A medical waste bin includes a barrel body 1, a barrel cover 2, a pedal mechanism 4 and an elastic component 5. The top of the barrel body 1 is open for containing waste. A hinge component 3 for hingedly connecting the barrel cover 2 is provided on the outer wall below the opening of the barrel body 1, so that the barrel cover 2 can be rotated and opened and closed at the opening of the barrel body 1. The pedal mechanism 4 can drive the barrel cover 2 to rotate around the hinge shaft 33 of the hinge component 3 under the force of the pedal, so as to realize the automatic opening and closing of the barrel cover 2; at the same time, the elastic component 5 provided on the barrel cover 2 can deform and store energy in the process of the barrel cover 2 covering the barrel body 1, so that the barrel cover 2 slowly covers the barrel body 1 under the action of gravity, so as to avoid fanning out the odor in the barrel body 1.

[0034] In order to enable the pedal mechanism 4 to smoothly drive the barrel cover 2 to open and close, refer to Figure 1 and Figure 2 The hinge assembly 3 includes a first connecting member fixed on the barrel cover 2 and a second connecting member fixed on the barrel body 1. The end of the first connecting member away from the barrel cover 2 and the end of the second connecting member away from the barrel body 1 are hingedly connected through a first rotating pair, so that a certain distance is left between the first rotating pair and the side wall of the barrel body 1, and the barrel cover 2 can be rotated and closed on the barrel body 1. In order to facilitate the processing and forming of the hinge assembly 3, in the embodiment of the present application, the first connecting member is set as a pair of connecting ears 31 fixed on the outer wall of the barrel cover 2, and the second connecting member is set as a fixed ear 32 fixed on the outer wall of the barrel body 1. The first rotating pair is a hinge shaft 33 fixedly installed between the pair of connecting ears 31. The hinge shaft 33 is rotated and inserted in the fixed ear 32, so that the connecting ear 31 is hingedly connected with the fixed ear 32, and then the barrel cover 2 is rotated and installed on the barrel body 1. In order to further ensure that the rotating closing of the barrel cover 2 is more stable, in the embodiment of the present application, two groups of hinge assemblies 3 are provided, and the two groups of hinge assemblies 3 are arranged between the barrel cover 2 and the barrel body 1 at intervals.

[0035] Reference Figure 1 , Figure 3 and Figure 4, a third connecting member 6 is also provided on the barrel cover 2, and the third connecting member 6 is located between the two sets of hinge components 3, and the end of the third connecting member 6 away from the barrel cover 2 forms a connection point connected to the pedal mechanism 4, and the connection point is located in the spacing between the first rotating pair and the side wall of the barrel body 1. In the embodiment of the present application, the third connecting member 6 includes two connecting plates 61 and a connecting shaft 62 fixed between the two connecting plates 61, and the connecting shaft 62 is located in the spacing between the first rotating pair and the side wall of the barrel body 1.

[0036] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The pedal mechanism 4 includes a pedal 41 and a top plate 42. One end of the pedal 41 is a pedal portion 411 and the other end is a connecting portion 412. The middle part of the pedal 41 is mounted at the bottom of the barrel body 1 through a second rotational pair. The second rotational pair is specifically configured as a mounting shaft 7, so that the pedal 41 can rotate at the bottom of the barrel body 1 under the connection of the mounting shaft 7. The top plate 42 is located at one side of the barrel body 1 where the hinge assembly 3 is provided, and the lower end of the top plate 42 is hingedly connected to the end of the connecting portion 412, and the upper end is hingedly connected to the barrel cover 2 through a connecting shaft 62, so that by stepping on the pedal portion 411, the connecting portion 412 is tilted upward, and the top plate 42 pushes the third connecting member 6 to drive the barrel cover 2 to rotate in a direction away from the barrel body 1, thereby opening the barrel cover 2. When the pedal 41 is no longer stepped on, the barrel cover 2 rotates toward the barrel body 1 under the action of gravity. At this time, the third connecting member 6 presses down on the top plate 42, and the top plate 42 pushes the connecting portion 412 to rotate downward, and the pedal portion 411 tilts upward and resets.

[0037] In order to make the elastic component 5 deform and store energy smoothly when the barrel cover 2 is closed on the barrel body 1, refer to Figure 2 , Figure 3 , Figure 4 and Figure 6The elastic component 5 includes a flexible elastic expansion member, and two groups of elastic expansion members are arranged at intervals. In other embodiments, the elastic expansion member is set as an elastic rope, and in the embodiment of the present application, the elastic expansion member includes a spring 51 and a connecting rope 52 fixed to one end of the spring 51. The spring 51 and the connecting rope 52 are both located on the inner wall of the barrel cover 2, one end of the spring 51 is fixedly connected to the inner wall of the barrel cover 2, and the other end is fixedly connected to the connection point of the third connecting member 6 and the top plate 42 through the connecting rope 52. At the same time, the spring 51 is always in a pulling rope state, so that the connecting rope 52 is always in a tensioned state. When the barrel cover 2 is rotated toward the barrel body 1 to close, the barrel cover 2 drives the spring 51 and the connecting rope 52 to move toward the barrel body 1. When the third connecting piece 6 is rotated to below the top opening of the barrel body 1, one end of the connecting rope 52 is located below the top opening of the barrel body 1 and the other end is located above the top opening of the barrel body 1, so that the connecting rope 52 abuts against the edge of the top of the barrel body 1 and bends, so that the connecting rope 52 pulls the spring 51 to stretch, causing the spring 51 to deform and store energy. At this time, the barrel cover 2 can be slowly closed on the barrel body 1 under the elastic force of the spring 51, avoiding fanning out of the odor in the barrel body 1.

[0038] Considering the sealing performance of the barrel cover 2 on the barrel body 1, Figure 2 , Figure 3 and Figure 5 A receiving groove 10 for the connecting rope 52 to be inserted is provided on one side of the top of the barrel body 1 near the hinge assembly 3. When the barrel cover 2 is sealed on the barrel body 1, the connecting rope 52 is located in the receiving groove 10. To further prevent the connecting rope 52 from being worn off, the bottom wall of the receiving groove 10 is set in an arc shape, so that the connecting rope 52 is not easily worn off and broken when it is tightly fitted on the bottom wall of the receiving groove 10.

[0039] Reference Figure 2 , Figure 3 and Figure 4 A baffle frame 9 is installed on the inner wall of the barrel cover 2, and a channel is opened on the side wall of the baffle frame 9 near the third connecting member 6. The spring 51 is located in the baffle frame 9, and the end of the connecting rope 52 away from the spring 51 passes through the channel and is fixedly connected to the connection point of the third connecting member 6 and the top plate 42. The surface of the baffle frame 9 near the channel is set as an arc surface, so that the tensioned connecting rope 52 contacts the arc surface on the baffle frame 9, reducing the risk of the connecting rope 52 being worn.

[0040] In order to facilitate the fast hinge connection between the fixing ear 32 and the connecting ear 31 through the hinge shaft 33, refer to Figure 1 , Figure 4 and Figure 5In the embodiment of the present application, a mounting groove 8 for inserting the hinge shaft 33 is provided on the fixing ear 32, and the notch of the mounting groove 8 is downwardly opened, so that the hinge shaft 33 on the barrel cover 2 can be inserted into the mounting groove 8 from the notch of the mounting groove 8 under the support of the top plate 42. In order to enable the hinge shaft 33 to rotate smoothly in the mounting groove 8, the inner wall of the top of the mounting groove 8 is set to be an arc shape adapted to the hinge shaft 33, and a connecting structure 11 for enabling the hinge shaft 33 to rotate smoothly is provided between the fixing ear 32 and the connecting ear 31. In the embodiment of the present application, the connecting structure 11 includes two first arc strips 111 respectively installed at both ends of the fixing ear 32 and two second arc strips 112 installed on the surface of one side of a pair of connecting ears 31 close to each other, the center of the circle where the first arc strip 111 is located coincides with the center of the circle where the arc-shaped inner wall of the mounting groove 8 is located, and the center of the circle where the second arc strip 112 is located is located on the central axis of the hinge shaft 33. A slot for accommodating the first arc strip 111 is formed between the inner wall of the second arc strip 112 and the hinge shaft 33, and the inner diameter of the second arc strip 112 is the same as the outer diameter of the first arc strip 111. When the top plate 42 pushes the barrel cover 2 to rotate on the barrel body 1 to open and close, the first arc strip 111 is always rotated and locked in the slot.

[0041] The implementation principle of a medical waste bin in the embodiment of the present application is as follows: when the bin needs to be opened, the third connecting member 6 is pushed by the top plate 42 to drive the barrel cover 2 to rotate in a direction away from the barrel body 1 by stepping on the pedal 411, causing the connecting member 412 to tilt upward, thereby opening the barrel cover 2. When the pedal 41 is no longer stepped on, the barrel cover 2 rotates toward the barrel body 1 under the action of gravity, and the barrel cover 2 drives the spring 51 and the connecting rope 52 to move toward the barrel body 1. When the third connecting member 6 rotates to the bottom of the top opening of the barrel body 1, one end of the connecting rope 52 is located below the top opening of the barrel body 1, and the other end is located above the top opening of the barrel body 1, so that the connecting rope 52 abuts against the edge of the top of the barrel body 1 and bends, so that the connecting rope 52 pulls the spring 51 to stretch, prompting the spring 51 to deform and store energy. At this time, the barrel cover 2 can slowly cover the barrel body 1 under the elastic force of the spring 51, thereby avoiding fanning out the odor in the barrel body 1.
