[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a household appliance plastic injection molded part, including an injection molded part body 1, the inner surface wall of the injection molded part body 1 is provided with multiple groups of movable grooves 2, rotating rods 3 are movably inserted between the inner surface walls of the multiple groups of movable grooves 2, the outer surfaces of the multiple rotating rods 3 are fixedly sleeved with dustproof blades 4, the outer surfaces of the multiple rotating rods 3 are fixedly sleeved with gears 5, the outer surfaces of the multiple gears 5 are meshedly connected with racks 6, the bottom of the rack 6 is fixedly connected with a slider 7, the inner surface wall of the slider 7 is threadedly connected with a threaded rod 8, the top of the injection molded part body 1 is provided with a slide groove 9, and the outer surface wall of the slider 7 is movably embedded in the slide groove 9, and a knob 10 is fixedly connected to one side of the outer wall of the threaded rod 8.

[0025] The effect achieved by the entire embodiment 1 is that when the household appliance is not in use, the user can rotate the knob 10, and the knob 10 drives the threaded rod 8 to rotate. Since the outer wall of the threaded rod 8 is threadedly connected with the slider 7, and the outer wall of the slider 7 is movably embedded in the inside of the slide groove 9, the rotation of the threaded rod 8 drives the slider 7 to move back and forth in the slide groove 9. The movement of the slider 7 simultaneously pulls the rack 6 to make a corresponding displacement. Since the outer wall of the rack 6 is meshedly connected with multiple gears 5, the rotation of the rack 6 drives the multiple gears 5 to rotate synchronously. The rotation of each gear 5 will respectively drive the corresponding rotating rod 3 to rotate, thereby causing the multiple dust-proof blades 4 to rotate accordingly. When the multiple dust-proof blades 4 rotate When the dust-proof blades 4 are rotated to a specific angle and are in a parallel state, the multiple dust-proof blades 4 will jointly form a closed barrier, which can effectively prevent external dust from entering the interior of the appliance through the ventilation holes, thereby ensuring the cleanliness and safety of the household appliance when not in use. By adjusting the angles of the multiple dust-proof blades 4, the ventilation gap of the injection molded part body 1 can be changed. In winter, since the heat dissipation requirements of household appliances are relatively low, the user can adjust the knob 10 to rotate the multiple dust-proof blades 4 to a specific angle, thereby reducing the ventilation gap between two adjacent dust-proof blades 4. This not only ensures the basic heat dissipation requirements of household appliances, but also can prevent dust from entering the interior of the appliance through the ventilation gap to the greatest extent.

[0026] Embodiment 2, as Figure 2-Figure 5 As shown, two clamping blocks 11 are fixedly connected to the bottom of the injection molding body 1, and one side of the outer wall of the two clamping blocks 11 is provided with an installation groove 12, and the inner wall of the two installation grooves 12 is fixedly connected with a return spring 13, and the outer wall of the two return springs 13 is fixedly connected to a limiting block 14, and two guide blocks 15 are fixedly connected to the bottom of the injection molding body 1, and an electrical appliance body 16 is movably sleeved between the outer walls of the two guide blocks 15, and the top of the electrical appliance body 16 is provided with two guide grooves 17, and the outer walls of the two guide blocks 15 are movably inserted in the two guide grooves 17, and the top of the electrical appliance body 16 is provided with two clamping grooves 18, and the outer walls of the two clamping blocks 11 are movably inserted in the two clamping grooves 18, and one side of the outer wall of the electrical appliance body 16 is provided with two limiting grooves 19, and the outer walls of the two limiting blocks 14 are movably inserted in the two limiting grooves 19.

[0027] The effect achieved by the entire embodiment 2 is that, by accurately inserting the two guide blocks 15 into the corresponding guide grooves 17, the injection molded part body 1 and the electrical appliance body 16 can achieve a preliminary stable connection. During this process, the two clamping blocks 11 will be smoothly inserted into the corresponding clamping grooves 18. At this time, the inclined surfaces of the two limit blocks 14 will contact the inner walls of the two clamping grooves 18 and be squeezed by the inner walls of the clamping grooves 18, thereby allowing the two limit blocks 14 to enter the corresponding installation grooves 12. Since the outer wall side of the two limit blocks 14 is fixedly connected with the return spring 13, the limit blocks 14 are The movement of the limit block 14 will squeeze the return spring 13, causing it to deform and store elastic potential energy. When the two blocks 11 completely enter the slot 18, the position of the limit block 14 will correspond to the position of the limit slot 19. At this time, under the elastic action of the return spring 13, the limit block 14 will quickly reset and accurately snap into the inside of the limit slot 19, thereby realizing the rapid installation of the injection molding body 1. When the injection molding body 1 needs to be disassembled, the injection molding body 1 can be easily removed from the electrical appliance body 16 by simply pressing the two limit blocks 14.

[0028] Working principle: When in use, first align the two guide blocks 15 with the two guide grooves 17. Through the precise docking of the guide blocks 15 and the guide grooves 17, the injection molded part body 1 and the electrical appliance body 16 are initially and firmly connected. During this process, the two clamping blocks 11 are smoothly inserted into the two clamping grooves 18. At the same time, the two limit blocks 14 are squeezed and the two return springs 13 are respectively compressed. When the two clamping blocks 11 completely enter the two clamping grooves 18, the two limit blocks 14 are precisely clamped into the two limit grooves 19 under the elastic action of the two return springs 13, so that The quick installation of the injection molded part body 1 is completed quickly. When the household appliance is idle, the user rotates the knob 10. The rotation of the knob 10 drives the threaded rod 8 to rotate. The threaded connection between the threaded rod 8 and the slider 7 makes the slider 7 move back and forth inside the slide groove 9. The slider 7 then drives the rack 6 to move. The movement of the rack 6 drives the multiple gears 5 to rotate. The rotation of the multiple gears 5 in turn rotates the multiple dust-proof blades 4 through the multiple rotating rods 3. When the multiple dust-proof blades 4 rotate to a parallel state, a closed barrier is formed to effectively prevent dust from entering and protect the household appliance.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
