Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a self-cleaning electric knife includes a knife body 1 and a cleaning assembly 2 disposed on the knife body 1. The cleaning component 2 comprises a fixed sleeve 3 fixedly connected with the cutter body 1, a movable sleeve 4 detachably connected with the fixed sleeve 3, a cleaning sleeve 5 connected on the cutter body 1 in a sliding manner, and a tension spring 6 connecting the cleaning sleeve 5 and the movable sleeve 4.

As shown in fig. 2 and 3, the fixing sleeve 3 is bonded to the cutter body 1 through a glue, and an external thread is formed on the outer side of the fixing sleeve 3. The inner side of the movable sleeve 4 is formed with an internal thread which is in threaded fit with the fixed sleeve 3, and the movable sleeve 4 is connected with the fixed sleeve 3 through threaded fit. One side of the movable sleeve 4 facing the top end of the cutter body 1 is inwards formed with a limiting ring 7, and the position of the movable sleeve 4 is fixed by the tight abutting of the limiting ring 7 and the end surface of the fixed sleeve 3. A first ring hook 8 is formed at the position, close to the center, of one side, facing the top end of the cutter body 1, of the limiting ring 7. A protection barrel 9 with a circular ring-shaped section is formed at the edge of the end face of the limiting ring 7 towards one side of the top end of the cutter body 1, a guide strip 10 parallel to the axis of the protection barrel 9 is formed on the inner wall of the protection barrel 9, and avoidance openings 11 are respectively formed in two side positions of one end, far away from the limiting ring 7, of the protection barrel 9. An arc-shaped accommodating groove 12 is formed on the end face of the limiting ring 7 at a position close to the two avoidance openings 11.

As shown in fig. 2 and 4, the inner wall of the cleaning sleeve 5 is attached to the outer wall of the cutter body 1, and a second ring hook 13 is formed at a position opposite to the first ring hook 8 (shown in fig. 3) on the side of the cleaning sleeve 5 facing the movable sleeve 4. Two ends of the tension spring 6 are respectively hooked with the first ring hook 8 and the second ring hook 13. The outer side wall of the cleaning sleeve 5 is formed with a guide groove 14 matched with the guide strip 10, and the cleaning sleeve 5 moves linearly on the cutter body 1 through the matching of the guide groove 14 and the guide strip 10. The cleaning sleeve 5 is provided with a sealing plate 15 with a section equal to that of the accommodating groove 12 at the position close to the two sides of one end of the movable sleeve 4. Each sealing plate 15 corresponds to the avoidance port 11, and the sealing plates 15 are attached to the inner wall of the protection cylinder 9 and have a width larger than that of the avoidance port 11. The edge of one end of the cleaning sleeve 5 facing the top end of the cutter body 1 is formed with an arc chamfer 16. When the tension spring 6 drives the cleaning sleeve 5 to be retracted into the protection cylinder 9, the sealing plate 15 is inserted into the accommodating groove 12, and the part of the cleaning sleeve 5 without the inverted arc surface chamfer 16 is fully retracted into the protection cylinder 9.

The specific working process is as follows:

when tissues and blood coagulates on the cutter body 1 are cleaned in the operation process, hands press the two sides of the cleaning sleeve 5 from the avoiding opening 11, and then the cleaning sleeve 5 is driven to move towards the top end of the cutter body 1. When the cleaning sleeve 5 slides along the cutter body 1, coagulations such as tissues, blood and the like on the cutter body 1 are removed from the cutter body 1. Then the cleaning sleeve 5 is loosened, and the cleaning sleeve 5 is restored and collected in the protective cylinder 9 under the action of the tension spring 6.

When the operation is finished and the whole electric knife needs to be cleaned and disinfected, the movable sleeve 4 is detached from the fixed sleeve 3, and the parts of the cleaning assembly 2 except the fixed sleeve 3 are detached into parts to be cleaned and disinfected independently, so that the cleaning assembly 2 can be cleaned completely.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
