[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] This specific embodiment is a self-unloading worm gear type can opener, and its structural schematic diagram is shown below. Figures 1-7 As shown, the can opener includes a body 1, a drive wheel assembly 2, a cutting wheel assembly 3, a drive component 4, and a transmission worm shaft 403. The drive wheel assembly 2 includes a guide bushing 201 that cooperates with the transmission worm shaft 403 and a drive wheel body 202. The drive wheel body 202 is fixedly connected to the outer surface of the guide bushing 201. A plastic bracket 102 is fixedly connected inside the body 1. The drive component 4 is movably connected to one side of the plastic bracket 102 through a disc spring 1023. The guide bushing 201 is slidably connected to the plastic bracket 102, and an elastic element 204 is installed between the guide bushing 201 and the inner wall of the body 1. The guide bushing 201 passes through the plastic bracket 102. By fixing the plastic bracket 102 inside the machine body 1, the drive wheel set 2 and the cutting wheel set 3 are installed on the plastic bracket 102, and the drive wheel set 2 is movably connected to the plastic bracket 102 through the disc spring 1023. When the drive assembly 4 drives the transmission worm shaft 403 to rotate, and the distance between the drive wheel set 2 and the cutting wheel set 3 is too tight, the drive assembly 4 can slide on the plastic bracket 102 and unload the force through the disc spring 1023, thereby increasing the distance between the drive wheel set 2 and the cutting wheel set 3, thus adapting to can walls of different thicknesses, avoiding the drive assembly 4 from getting stuck and unable to rotate, and achieving better performance. Because the top edge of the can has a certain curvature, the cutting wheel of the cutting wheel group 3 can be arranged at an angle along the direction of travel, with the end facing down and maintaining a certain angle with the horizontal wall. The angle of inclination is between 5 and 30°, so that the blade of the cutting wheel cuts into the can at an upward angle, and the bottom surface can roll the cut edge of the can after cutting to flatten it, making it less likely to cut your hand.

[0027] like Figure 4 and Figure 5As shown: In this embodiment, the drive assembly 4 includes a drive motor 401 and a gearbox 402 mounted on the drive motor 401. The transmission worm shaft 403 is fixedly connected to the output end of the gearbox 402. A first mounting groove 1021 is provided on the side of the plastic bracket 102 near the drive assembly 4. The gearbox 402 is located in the first mounting groove 1021. A plurality of slide rods 1022 are fixedly connected on the side of the gearbox 402 away from the drive motor 401. The other end of the slide rod 1022 passes through the plastic bracket 102 and is fixedly connected to a disc spring 1023. Preferably, there are three slide rods 1022. The first mounting groove 1021 is provided on the plastic bracket 102. The disc spring 1023 is located in the first mounting groove 1021. The drive motor 401 is connected to the internal circuit board through a flexible wire to prevent the drive assembly 4 from jamming.

[0028] like Figure 5 As shown: In this embodiment, a guide groove 203 is provided at one end of the guide sleeve 201, and a guide pin 2031 that cooperates with the guide groove 203 is fixedly connected to the outer surface of the transmission worm shaft 403. Under the action of the elastic member 204, the guide pin 2031 on the transmission worm shaft 403 can always fit against the inclined surface of the guide groove 203 of the guide sleeve 201. When not working, the guide pin is always located at the lowest point of the inclined surface of the guide groove 203.

[0029] To increase friction, such as Figure 5 As shown: In this embodiment, the drive wheel body 202 has an annular stepped groove 205 on the side near the cutting wheel assembly 3. The inner wall of the stepped groove 205 has a toothed groove, which is used to increase the friction with the edge of the can.

[0030] like Figure 3 and Figure 4 As shown: In this embodiment, an L-shaped mounting position 101 is provided on the machine body 1. The interior of the machine body 1 forms a drive wheel mounting cavity and a cutting wheel mounting cavity through the L-shaped mounting position 101. The plastic bracket 102 has an L-shaped structure and is fixedly installed in the drive wheel mounting cavity and the cutting wheel mounting cavity. A second mounting groove 103 is provided on the side of the plastic bracket 102 in the cutting wheel mounting cavity near the L-shaped mounting position 101. The cutting wheel assembly 3 is rotatably installed in the second mounting groove 103. By setting the plastic bracket 102, not only is the movement of the guide bushing 201 guided, but the installation of the cutting wheel assembly 3 is also facilitated, making the movement of the drive wheel body 202 driven by the guide bushing 201 more stable.

[0031] like Figure 4 and Figure 5As shown: In this embodiment, the elastic element 204 is a spring. A spring seat 104 is fixedly connected to the inner wall of the cutting wheel mounting cavity. A groove is provided on the spring seat 104. One end of the elastic element 204 is sleeved on the outer surface of the guide sleeve 201, and the other end of the elastic element 204 is located in the groove. By setting the spring seat 104, it is easy to fix the elastic element 204 and sleeve it on the outer surface of the guide sleeve 201, making it more convenient to replace the elastic element 204.

[0032] like Figure 1 , Figure 3 and Figure 7 As shown: In this embodiment, a magnet 6 is fixedly connected to the L-shaped mounting position 101, which allows the body 1 to be firmly attached to the top of the can and to lift the can lid after it is opened. A switch 7 is installed on the outer surface of the body 1, and two charging contacts 8 are installed at the bottom of the body 1. The body 1 is mounted on the charging base 9 through the charging contacts 8. The charging base 9 is provided with a charging port 901 and an inclined charging placement slot 902. The top of the charging placement slot 902 has a clearance groove 903 corresponding to the magnet 6, and the bottom of the charging placement slot 902 is fixedly connected to a charging pin 904 corresponding to the charging contact 8. The charging pin 904 is electrically connected to the charging port 901. When in use, the charging base 9 is placed on a table and connected to the power supply through the charging port 901. In this way, the body 1 can be placed in the inclined charging placement slot 902 without tipping over. At this time, the charging pin 904 at the bottom of the charging placement slot 902 contacts the charging contacts 8 at the bottom of the body 1, which facilitates charging. This is very convenient.

[0033] Working principle: After the can opener is started, the drive motor 401 works, which drives the transmission worm shaft 403 to rotate through the drive wheel set 2. At this time, the guide pin 2031 on the transmission worm shaft 403 pushes the guide sleeve 201 to move horizontally through the guide groove 203, and compresses the elastic element 204. The drive wheel body 202 moves automatically towards the cutting wheel set 3 under the drive of the guide sleeve 201 to clamp the can lip, so that the blade of the cutting wheel set 3 cuts into the can. Under the continuous rotation of the transmission worm shaft 403, the drive wheel body 202 and the cutting wheel set 3 always maintain a clamped state on the can lip, and the drive wheel body 202 moves automatically along the top of the can lip. The cutting wheel set 3 cuts the can lip, and finally completes the automatic opening. When the drive assembly 4 drives the transmission worm shaft 403 to rotate, causing the distance between the drive wheel set 2 and the cutting wheel set 3 to be too tight, the drive assembly 4 can slide on the plastic bracket 102 and relieve the force through the disc spring 1023, thereby increasing the distance between the drive wheel set 2 and the cutting wheel set 3, thus adapting to can walls of different thicknesses, avoiding the drive assembly 4 from getting stuck and unable to rotate, and achieving better performance.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
