A filter disc for a food waste disposer

Abstract

This utility model discloses a filter disc for a food waste disposer, relating to the field of filter discs. This utility model, by incorporating a scraper, a first slider, a second slider, rollers, and a guide plate, ensures that when the user uses the filter disc, the scraper can smoothly remove residual solid food waste from the outer wall of the filter disc through its sliding motion. Simultaneously, through the arrangement of a limiting strip, a linkage column, a linkage rod, a rotating base, a limiting block, a spring, and a limiting block, as the user continues to rotate the filter disc, when the bottom of the filter disc is perpendicular to the ground, gravity causes the linkage rod to rotate and contact the limiting strip, restricting the rollers. This allows the scraper to move to the other end of the filter disc under the influence of gravity. At this point, the scraper, restrained by the first and second sliders, impacts the filter disc, generating vibration, which causes the residual solid food waste inside the filter disc to fall off the outer wall of the filter disc due to the impact and vibration.

Description

Technical Field

[0001] This utility model relates to the field of filter discs, specifically a filter disc for food waste disposers. Background Technology

[0002] Food waste disposers separate liquid food waste from solid food waste. Liquid food waste contains grease and wastewater, and a large amount of grease entering the sewer can easily cause pipe blockage, reduce the lifespan of the sewer, and increase the cost and trouble of pipe cleaning. At the same time, the separated grease can be specially treated and recycled, preventing grease from being directly discharged into the sewer and water bodies, reducing environmental pollution and helping to protect water resources and the ecological environment. After the grease is separated, the remaining solid food waste is easier to crush and process, which can improve the overall operating efficiency of the food waste disposer and reduce machine failures and wear caused by excessive grease.

[0003] The filter disc is installed at the inlet of the food waste disposer or the drain outlet of the sink. It can intercept larger food scraps and solid waste, preventing them from entering the disposer and causing blockages or damage. It also allows grease and wastewater to enter the disposer more smoothly for subsequent processing. At the same time, by rotating the filter disc, the separated solid food waste can be moved to the solid food waste collection bin for users to better process the solid food waste.

[0004] Existing filter discs separate liquid and solid food waste, which is then collected by the solid food waste collection bin. This allows for centralized collection of solid food waste. However, the initially separated solid food waste tends to adhere to the outer wall of the filter disc, requiring manual cleaning of the filter disc. This increases the user's workload and reduces the efficiency of the food waste disposer. Summary of the Invention

[0005] Based on this, the purpose of this utility model is to provide a filter disc for a food waste disposer to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter disc for a food waste disposer, comprising a food waste disposer and a filter disc, a rotating shaft fixedly mounted on the outer wall of the filter disc, a scraper slidably mounted inside the filter disc, and a first slider fixedly mounted on the outer wall of the scraper. The scraper slides inside the filter disc, driving the first slider to slide inside the filter disc. A second slider is fixedly mounted on the outer wall of the scraper, and a roller is rotatably mounted on the outer wall of the second slider. A guide plate corresponding to the roller is fixedly mounted on the outer wall of the filter disc. The roller begins to move within the guide plate, driving the scraper to begin sliding within the filter disc, and the guide plate slides within the guide plate... The device is equipped with a limiting strip, and a linkage column is fixedly installed on the outer wall of the limiting strip. A linkage rod is slidably installed on the outer wall of the linkage column. A rotating base is rotatably installed on the outer wall of the linkage rod. A limit block is slidably installed inside the filter disc, and a spring is sleeved on the outer wall of the limit block. Under the action of the spring, the limit block begins to restrict the position of the limiting strip. A limit block corresponding to the linkage rod is fixedly installed on the inner wall of the food waste disposer. Due to the restriction of the limit block, the linkage rod begins to rotate on the outer wall of the filter disc, which in turn causes the linkage column at the other end of the linkage rod to rotate and slide inside the linkage rod, thereby pulling the limiting strip to slide inside the guide plate.

[0007] By adopting the above technical solution, it is ensured that when using the filter disc, the user can smoothly remove the solid food waste remaining in the filter disc from the outer wall of the filter disc by sliding the scraper. At the same time, through the setting of the limiting strip, linkage column, linkage rod, rotating base, limit block, spring and limiting block, as the user continues to rotate, when the bottom of the filter disc is perpendicular to the ground, under the action of gravity, the rotation of the linkage rod contacts the limiting strip to restrict the roller, so that the scraper can move to the other end of the filter disc under the action of gravity. At this time, the scraper and the filter disc collide with the filter disc under the restriction of the first slider and the second slider, generating vibration, which causes the residual solid food waste in the filter disc to fall off the outer wall of the filter disc under the impact and vibration, further realizing the cleaning of the filter disc.

[0008] Furthermore, the scraper has through holes corresponding to the filter disc, and two sets of first sliders are symmetrically arranged on the outer wall of the scraper, and two sets of second sliders are symmetrically arranged on the outer wall of the scraper.

[0009] By adopting the above technical solution, the sliding of the scraper within the filter disc is ensured to be more stable.

[0010] Furthermore, the guide plate is parallel to the bottom edge of the filter disc.

[0011] By adopting the above technical solution, it is ensured that the scraper always stays in contact with the bottom edge of the filter disc under the guidance of the roller.

[0012] Furthermore, the linkage column has a circular cross-section, and the linkage rod has a groove corresponding to the linkage column.

[0013] By adopting the above technical solution, it is ensured that the linkage column slides smoothly within the linkage rod while rotating within the linkage rod.

[0014] Furthermore, the rotating base is located at the center of the linkage rod, and the rotating base is fixedly connected to the filter disc.

[0015] By adopting the above technical solution, the rotation of the linkage rod is ensured to be smoother, and the linkage rod can better drive the limit bar.

[0016] Furthermore, the end section of the limiting block is designed with a circular structure, and the limiting strip has a groove corresponding to the limiting block.

[0017] By adopting the above technical solution, it is ensured that when the limiting bar moves to the corresponding position, it can remain stable due to the restriction of the limiting block.

[0018] Furthermore, one end of the spring is in contact with the inner wall of the filter disc, and the other end of the spring is in contact with the outer wall end of the limiting block.

[0019] By adopting the above technical solution, it is ensured that the limit block can successfully limit the position of the limit bar.

[0020] Furthermore, two sets of limiting blocks are arranged inside the food waste disposer with the rotating shaft as the center. The angle between the limiting blocks and the ground is less than 90 degrees, and the linkage rod is located between the two sets of limiting blocks.

[0021] By adopting the above technical solution, it is ensured that the scraper can be better subjected to gravity, thereby achieving better impact on the filter disc.

[0022] This invention, by incorporating a scraper, a first slider, a second slider, rollers, and a guide plate, ensures that when using the filter disc, the user can smoothly remove residual solid food waste from the outer wall of the filter disc through the sliding of the scraper. Simultaneously, through the arrangement of a limiting strip, a linkage column, a linkage rod, a rotating base, a limiting block, a spring, and a limiting block, as the user continues to rotate the filter disc, when the bottom of the filter disc is perpendicular to the ground, gravity causes the linkage rod to rotate and contact the limiting strip, restricting the rollers. This allows the scraper to move to the other end of the filter disc under the influence of gravity. At this point, the scraper, restrained by the first and second sliders, impacts the filter disc, generating vibration. This vibration causes residual solid food waste to fall from the outer wall of the filter disc, further achieving the cleaning of the filter disc. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] A filter disc for food waste disposers, such as Figure 1 - Figure 5As shown, the device includes a food waste disposer 1 and a filter tray 2. A rotating shaft 21 is fixedly installed on the outer wall of the filter tray 2. A scraper 3 is slidably installed inside the filter tray 2, and a first slider 31 is fixedly installed on the outer wall of the scraper 3. The scraper 3 slides inside the filter tray 2, causing the first slider 31 to slide inside the filter tray 2. A second slider 32 is fixedly installed on the outer wall of the scraper 3, and a roller 4 is rotatably installed on the outer wall of the second slider 32. A guide plate 41 corresponding to the roller 4 is fixedly installed on the outer wall of the filter tray 2. The roller 4 begins to move within the guide plate 41, causing the scraper 3 to begin to slide inside the filter tray 2. A limiting strip 5 is slidably installed inside the guide plate 41, and the outer wall of the limiting strip 5 is fixedly installed. A linkage column 51 is fixedly installed, and a linkage rod 6 is slidably installed on the outer wall of the linkage column 51. A rotating base 61 is rotatably installed on the outer wall of the linkage rod 6. A limit block 7 is slidably installed inside the filter disc 2, and a spring 71 is sleeved on the outer wall of the limit block 7. Under the action of the spring 71, the limit block 7 begins to restrict the position of the limit strip 5. A limit block 8 corresponding to the linkage rod 6 is fixedly installed on the inner wall of the food waste disposer 1. Due to the restriction of the limit block 8, the linkage rod 6 begins to rotate on the outer wall of the filter disc 2, which in turn causes the linkage column 51 at the other end of the linkage rod 6 to begin to rotate and slide inside the linkage rod 6, thereby pulling the limit strip 5 to slide inside the guide plate 41.

[0032] Please see Figure 1 - Figure 3 The scraper 3 has through holes corresponding to the filter disc 2. Two sets of first sliders 31 are symmetrically arranged on the outer wall of the scraper 3, and two sets of second sliders 32 are symmetrically arranged on the outer wall of the scraper 3. By restricting the first sliders 31 and the second sliders 32, the sliding of the scraper 3 in the filter disc 2 is made more stable.

[0033] Please see Figure 2 - Figure 3 The guide plate 41 is parallel to the bottom edge of the filter disc 2. When the roller 4 slides in the guide plate 41, it is always at the same level as the bottom of the filter disc 2, ensuring that the scraper 3 is always in contact with the bottom edge of the filter disc 2 under the guidance of the roller 4.

[0034] Please see Figure 2 The linkage column 51 has a circular cross-section. The linkage rod 6 has a corresponding groove. When the linkage rod 6 rotates, it drives the linkage column 51 to slide within the linkage rod 6, ensuring that the linkage column 51 slides smoothly within the linkage rod 6 while rotating within the linkage rod 6.

[0035] Please see Figure 3 The rotating base 61 is located at the center of the linkage rod 6, and the rotating base 61 is fixedly connected to the filter disc 2. Under the restriction of the rotating base 61, the rotation of the linkage rod 6 is ensured to be smoother, and the linkage rod 6 can better drive the limiting bar 5.

[0036] Please see Figure 2The end section of the limiting block 7 is designed with a circular structure. The limiting strip 5 has a groove corresponding to the limiting block 7. As the limiting strip 5 moves, the limiting block 7 restricts the movement of the limiting strip 5 to two different positions, ensuring that the limiting strip 5 can remain stable when it moves to the corresponding position due to the restriction of the limiting block 7.

[0037] Please see Figure 2 One end of the spring 71 is in contact with the inner wall of the filter disc 2, and the other end of the spring 71 is in contact with the outer end of the limiting block 7. Under the action of the spring 71's own stress, it is ensured that the limiting block 7 can smoothly limit the position of the limiting strip 5.

[0038] Please see Figure 1 and Figure 4 There are two sets of limiting blocks 8 inside the food waste disposer 1 with the rotating shaft 21 as the center. The angle between the limiting blocks 8 and the ground is less than 90 degrees. The linkage rod 6 is located between the two sets of limiting blocks 8. Under the restriction of the limiting blocks 8, as the filter disc 2 rotates, the linkage rod 6 can release the restriction on the limiting strip 5 at an angle where the bottom edge of the filter disc 2 is approximately perpendicular to the ground, ensuring that the scraper 3 can be better subjected to gravity, thereby achieving a better impact on the filter disc 2.

[0039] The working principle of this utility model is as follows: When a user uses the food waste disposer 1, solid and liquid food waste is first filtered through the filter disc 2. After the food waste is separated by the filter disc 2, the user rotates the filter disc 2 to move the solid food waste into the recycling bin outside the food waste disposer 1. As the user continues to rotate the filter disc 2, when the bottom edge of the filter disc 2 is rotated to a perpendicular position to the ground, the limiting block 8 causes the linkage rod 6 to begin rotating on the outer wall of the filter disc 2. This, in turn, causes the linkage column 51 at the other end of the linkage rod 6 to begin rotating and sliding within the linkage rod 6. Pull the limiting strip 5 to slide within the guide plate 41. As the limiting strip 5 slides, it no longer restricts the roller 4. At this time, under the action of the spring 71, the limiting block 7 begins to restrict the position of the limiting strip 5, thereby causing the roller 4 to move within the guide plate 41. This drives the scraper 3 to slide within the filter disc 2. Finally, under the action of gravity, the scraper 3 moves to the other end of the filter disc 2. At the same time, due to gravity, the scraper 3 collides with the filter disc 2, thereby causing the solid food waste in the filter disc 2 to separate from the filter disc 2 under the impact of the scraper 3, thus achieving better cleaning of the filter disc 2.

[0040] Similarly, when the user starts filtering the next batch of food waste, the filter disc 2 is first rotated to reset it. As the filter disc 2 continues to move, the scraper 3 begins to move towards the bottom of the filter disc 2. When the scraper 3 reaches the bottom of the filter disc 2, as the filter disc 2 rotates further, when the end of the linkage rod 6 comes into contact with another set of limiting blocks 8, the linkage rod 6 begins to rotate under the restriction of the limiting blocks 8, which in turn drives the limiting strip 5 to slide within the guide plate 41. At the same time, under the restriction of the limiting block 7, the roller 4 is thus restricted.
