Description

Technical Field

[0001] This application relates to the field of medical waste disposal, and in particular to a semi-automatic trash can. Background Technology

[0002] In the field of medical waste management, with the continuous development of the medical industry, the amount of medical waste generated by hospitals, clinics, and other medical institutions is increasing daily, making the effective collection and closed-loop treatment of medical waste increasingly important. Proper handling of medical waste is not only related to the environmental hygiene within medical institutions, but also to the safety and health of medical staff and the surrounding environment. Reasonable medical waste disposal methods can reduce the risk of bacterial and viral transmission, prevent medical waste from polluting the environment, and are of great significance for ensuring public health and safety.

[0003] Currently, the conventional method for collecting and sealing medical waste is to collect it directly in ordinary trash cans and then manually tie the trash bags tightly. This method is simple and low-cost, but manually tying the trash bags exposes people to direct contact with medical waste, liquids, or gases, which can easily cause health hazards to those who come into contact with it.

[0004] Therefore, preventing direct human contact with medical waste during the bag replacement and sealing process is an urgent issue that needs to be addressed. Utility Model Content

[0005] To prevent direct contact between the human body and medical waste during the process of changing and sealing trash can bags, this application provides a semi-automatic trash can, employing the following technical solution: A semi-automatic trash can includes a bin body, a first pressure bar, a second pressure bar, a transmission mechanism, and a manual operating component.

[0006] The first and second pressure strips have a clamping section in the middle and rotating shafts at both ends; the clamping section fits into the opening of the garbage bag. The rotating shaft is rotatably connected to the barrel body; The transmission mechanism is connected to the rotating shaft; The manual operating component is connected to the first pressure bar rotating shaft; the first pressure bar rotating shaft is rotatably connected to the second pressure bar through a transmission mechanism, so that the closure of the first and second pressure bars seals the garbage bag.

[0007] By adopting the above technical solution, the clamping sections of the first and second pressure strips fit against the opening of the garbage bag, the rotating shaft is rotatably connected to the bin body, the transmission mechanism is connected to the rotating shaft, and the manual operating component is connected to the rotating shaft of the first pressure strip. This allows the rotating shaft of the first pressure strip to drive the second pressure strip to rotate relative to it through the transmission mechanism, thereby closing the first and second pressure strips to seal the garbage bag. This design fundamentally avoids direct contact between the user and medical waste, residual liquids, or gases when sealing the garbage bag, effectively reducing the risk of cross-infection and health hazards, and significantly improving the safety of the medical waste disposal process.

[0008] Preferably, the transmission mechanism includes a bearing assembly and a gear assembly; the bearing assembly is mounted on the barrel body.

[0009] By adopting the above technical solution, the bearing assembly is installed on the barrel body and, together with the gear assembly, forms a transmission mechanism, so that the first pressure bar and the second pressure bar can rotate relative to each other, thereby closing the first pressure bar and the second pressure bar to seal the garbage bag.

[0010] Preferably, the gear assembly includes a first gear and a second gear; the first gear and the second gear mesh with each other; the first gear is fixed to the shaft of the first pressure bar; and the second gear is fixed to the shaft of the second pressure bar.

[0011] By adopting the above technical solution, the structure in which the first gear and the second gear mesh with each other can realize the opposite or reverse rotation of the first pressure bar and the second pressure bar, thereby realizing the closing and opening of the first pressure bar and the second pressure bar, improving the convenience of operation and the stability of garbage bag sealing. At the same time, the gear transmission can precisely control the rotation angle of the pressure bar to ensure the sealing quality of the garbage bag.

[0012] Preferably, the transmission mechanism further includes a one-way locking mechanism; the one-way locking mechanism is fixed on the barrel body; the one-way locking mechanism is connected to the rotating shaft of the first pressure bar; the one-way locking mechanism is used to restrict the rotating shaft of the first pressure bar from rotating in the opposite direction.

[0013] By adopting the above technical solution, a one-way locking mechanism connected to and fixed on the body of the bin is set in the transmission mechanism of the semi-automatic trash can. This can restrict the reverse rotation of the first pressure bar shaft, avoid the misoperation of reverse rotation when the first and second pressure bars are closed, and ensure the normal operation of the trash bag sealing operation.

[0014] Preferably, the one-way locking mechanism includes a ratchet and a pawl; the ratchet is disposed on the pivot of the first pressure bar; the pawl is fixed on the barrel body; the pawl abuts against the tooth groove of the ratchet; and a torsion spring is provided inside the pawl for pawl reset.

[0015] By adopting the above technical solution, a one-way locking mechanism composed of a ratchet and a pawl can be set to restrict the reverse rotation of the first pressure bar shaft and prevent accidental operation of reverse rotation. At the same time, when the pawl is moved to disengage from the ratchet, the manual operating part can be controlled to rotate in the reverse direction to open the two closed pressure bars. In addition, a torsion spring is provided inside the pawl for pawl reset, which can make the pawl automatically return to the state of abutting the ratchet after operation.

[0016] Preferably, the pressure strip is a round steel structure; the clamping section is provided with multiple hooks; the hooks are used to hook the edge of the garbage bag; the clamping section is covered with rubber material.

[0017] By adopting the above technical solutions, the pressure strip of the round steel structure ensures the structural strength; the hooks hold the edge of the garbage bag to prevent the garbage bag from slipping; the rubber-coated clamping section makes the garbage bag more evenly stressed when sealing, increases the friction with the garbage bag, further stabilizes the garbage bag, and improves the stability and success rate of sealing.

[0018] Preferably, the barrel body is provided with a protective cover; the protective cover covers the meshing areas of the bearing assembly, gear assembly, ratchet, and pawl.

[0019] By adopting the above technical solution, setting up a protective cover to cover the meshing areas of the bearing assembly, gear assembly, ratchet, and pawl, these components can be protected, preventing them from being affected by the external environment or accidentally touched. This ensures the stable and reliable operation of the transmission mechanism and one-way locking mechanism of the semi-automatic trash can, thereby ensuring that the trash can can properly seal the trash bag.

[0020] Preferably, the first pressure bar's rotating shaft is equipped with an automatic reset mechanism; the automatic reset mechanism includes a coil spring and a coil spring fixing plate; the coil spring fixing plate is fixed to the protective cover or barrel body; one end of the coil spring is connected to the rotating shaft of the first pressure bar; the other end of the coil spring is connected to the coil spring fixing plate.

[0021] By adopting the above technical solution and setting an automatic reset mechanism, one end of the coil spring is connected to the first pressure bar shaft and the other end is connected to the coil spring fixing plate fixed on the cover or the barrel body. This allows the first pressure bar to automatically reset after the closing operation, making it convenient to use the garbage can again to seal the garbage bag.

[0022] Preferably, the barrel body includes a barrel body, a fixing frame, and a bearing seat; the fixing frame is located at the opening edge of the barrel body; the fixing frame is detachably connected to the barrel body via a snap-fit ​​structure; the bearing seat is fixed to the fixing frame; and the bearing assembly is fixed to the bearing seat.

[0023] By adopting the above technical solution, the fixing frame is set at the edge of the opening of the bin and is detachably connected to the bin body through a buckle structure, which facilitates the installation and disassembly of the fixing frame and is conducive to later maintenance and replacement; the bearing seat is fixed on the fixing frame, which can provide stable support for the bearing assembly and ensure that the semi-automatic trash can can properly seal the trash bag.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. This semi-automatic trash can includes a bin body, a first pressure bar, a second pressure bar, a transmission mechanism, and a manual operating component. The first pressure bar is rotated by the manual operating component, and the second pressure bar is rotated by the transmission mechanism, thereby closing the pressure bar and sealing the trash bag to prevent direct contact between the human body and the trash bag and medical waste, thus protecting the health of personnel.

[0025] 2. By setting a one-way locking mechanism, the rotation of the first pressure bar can be restricted to reverse when it is closed, preventing accidental reverse rotation; the clamping section of the pressure bar is equipped with hooks and covered with rubber material to tightly fit and hook the edge of the garbage bag, preventing the garbage bag from slipping off; by setting an automatic reset mechanism, the first pressure bar can be automatically reset after the closing operation, which is convenient for subsequent use of the garbage can to seal the garbage bag.

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0028] A semi-automatic trash can, as shown in the reference Figures 1-2 The device includes a bin body 1, a first pressure strip 2, a second pressure strip 3, a transmission mechanism 4, and a manual operating component 5. The rotating shafts of the first pressure strip 2 and the second pressure strip 3 are rotatably connected to the bin body 1. The transmission mechanism 4 is connected to the rotating shaft. The manual operating component 5 is connected to the rotating shaft of the first pressure strip 2. The rotating shaft of the first pressure strip 2 is rotatably connected to the second pressure strip 3 through the transmission mechanism 4, so that the first pressure strip 2 and the second pressure strip 3 can be closed to seal the garbage bag.

[0029] The first pressure bar 2 is rotated by the manual operating component 5, and then the second pressure bar 3 is rotated by the transmission mechanism 4, thereby closing the pressure bar and sealing the garbage bag. The entire process does not require personnel to directly touch the garbage bag, fundamentally avoiding direct contact between the human body and the garbage bag for sealing operations, and reducing the harm to human health caused by medical waste and medicinal gases.

[0030] The first pressure strip 2 and the second pressure strip 3 have a clamping section in the middle and rotating shafts at both ends. The clamping section is the part that fits against the opening of the garbage bag, clamping the garbage bag tightly to achieve a seal when closed. The clamping section is a round steel structure and is equipped with multiple hooks 10. The hooks 10 can be protrusions used to hook the edge of the garbage bag to prevent it from slipping. Alternatively, the hooks 10 can also be hooks or other structures. The clamping section is also covered with rubber material, which increases the friction with the garbage bag, better clamping the garbage bag, and also preventing scratches on the garbage bag. The rotating shaft is the part that is rotatably connected to the bin body 1, allowing the pressure strips to rotate around the rotating shaft on the bin body 1 to achieve the closing and opening actions. The rotating shaft can be a smooth cylindrical stainless steel structure, facilitating smooth rotation at the corresponding installation position on the bin body 1.

[0031] The transmission mechanism 4 includes a bearing assembly 41 and a gear assembly 42. The bearing assembly 41 is mounted on the barrel 1 and supports the rotation of the shaft. The bearing assembly 41 can be a common rolling bearing, capable of rolling flexibly when the shaft rotates. Alternatively, other types of bearings, such as sliding bearings, can be used. The gear assembly 42 includes a first gear and a second gear, which mesh with each other. The first gear is fixed to the shaft of the first pressure bar 2, and the second gear is fixed to the shaft of the second pressure bar 3. When the shaft of the first pressure bar 2 rotates, the first gear rotates accordingly, driving the second gear to rotate through the meshing action of the gears, thereby causing the shaft of the second pressure bar 3 to rotate, achieving relative rotation between the first pressure bar 2 and the second pressure bar 3. The gears can be spur gears, helical gears, or other types of gears.

[0032] The transmission mechanism 4 also includes a one-way locking mechanism 6. The one-way locking mechanism 6 is fixed to the barrel body 1 and connected to the rotating shaft of the first pressure bar 2, used to restrict the reverse rotation of the rotating shaft of the first pressure bar 2. The one-way locking mechanism 6 includes a ratchet 61 and a pawl 62. The ratchet 61 is located on the rotating shaft of the first pressure bar 2, and the pawl 62 is fixed to the barrel body 1, abutting against the tooth groove of the ratchet 61. When the rotating shaft of the first pressure bar 2 rotates in the forward direction, the pawl 62 slides on the tooth groove of the ratchet 61; when attempting to rotate in the reverse direction, the pawl 62 will lock in the tooth groove of the ratchet 61, preventing reverse rotation. A torsion spring is provided inside the pawl 62 for resetting the pawl 62. When an external force causes the pawl 62 to leave the tooth groove of the ratchet 61, the torsion spring will cause the pawl 62 to return to the position abutting against the tooth groove of the ratchet 61.

[0033] refer to Figure 3 The barrel body 1 includes a barrel body 11, a fixing frame 12, and a bearing seat 13. The fixing frame 12 is located at the opening edge of the barrel body 11 and is detachably connected to the barrel body 11 via a snap-fit ​​structure, preferably a spring snap-fit ​​structure. The bearing seat 13 is fixed to the fixing frame 12 and is used to install the rotating shaft and bearing assembly 41, providing support for the rotation of the pressure strip. The bearing seat 13 can be fixed to the fixing frame 12 by bolts. The bearing seat 13 is generally made of metal, such as stainless steel, which has good strength and corrosion resistance, and its shape is usually square.

[0034] refer to Figure 4 The barrel body 1 is equipped with a protective cover 9, which covers the meshing areas of the bearing assembly 41, gear assembly 42, ratchet 61, and pawl 62. The protective cover 9 protects these components from external dust and debris, extending their service life, and also prevents accidental contact with these moving parts, improving safety during use. The protective cover 9 can be made of plastic or metal.

[0035] refer to Figure 5 The first pressure bar 2 has an automatic reset mechanism 7 on its rotating shaft. The automatic reset mechanism 7 includes a coil spring 72 and a coil spring fixing plate 71. The coil spring fixing plate 71 is fixed to the protective cover 9 or the barrel body 1. One end of the coil spring 72 is connected to the rotating shaft of the first pressure bar 2, and the other end is connected to the coil spring fixing plate 71. When the rotating shaft of the first pressure bar 2 is rotated, the coil spring 72 deforms and stores energy. When the external force disappears, the coil spring 72 releases the energy, causing the rotating shaft of the first pressure bar 2 to rotate in the opposite direction back to its initial position, thus achieving automatic reset. Alternatively, other types of elastic elements can be used to achieve the automatic reset function.

[0036] The implementation principle of this embodiment is as follows: The semi-automatic trash can controls the rotation of the first pressure bar 2 via a manual operating component 5, and the second pressure bar 3 rotates accordingly via a transmission mechanism 4, thereby closing the first and second pressure bars 2 and 3 to seal the trash bag and prevent direct contact between the human body and the trash bag. A one-way locking mechanism 6 prevents accidental reverse rotation of the pressure bars, improving operational safety and stability. An automatic reset mechanism 7 allows the pressure bars to automatically return to their initial position after operation, facilitating future use. The entire trash can structure is rationally designed, with each component working together to effectively solve the problems of potential harm from direct contact with the trash bag and inconvenient operation in existing technologies, thus improving the safety and convenience of medical waste disposal.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
