In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.

[0048] The crushing device of the first embodiment of the present application is described below with reference to the accompanying drawings.

[0049] Combine Figure 1-Figure 7As shown, the pulverizing device of the first embodiment of the present application mainly includes roller cutters 5 and spacers 6. Two sets of roller cutters 5 are arranged side by side and opposite to each other, and the two sets of roller cutters 5 can rotate in opposite directions to engage with each other. Each set of roller cutters 5 includes a rotating shaft 501 and a plurality of tooth blades 502. The plurality of tooth blades 502 are axially sleeved on the rotating shaft 501. The plurality of tooth blades 502 of the two sets of roller cutters 5 are staggered to form a first pulverizing area between the two sets of roller cutters 5. When the material contacts the tooth blades 502, the material is drawn between the staggered tooth blades 502 of the two sets of roller cutters 5, thereby achieving a primary pulverization of the material entering the first pulverizing area. The staggered arrangement of the teeth 502 of the two groups of hobs 5 in the embodiment of the present application can be understood as: the teeth 502 of the first group of hobs 5 are located in the interval between the adjacent teeth 502 of the second group of hobs 5, and the teeth 502 of the second group of hobs 5 are located in the interval between the adjacent teeth 502 of the first group of hobs 5; and since the two groups of hobs 5 are staggered, the first tooth 502 of the first group of hobs 5 and the last tooth 502 of the second group of hobs 5 are not in the interval.

[0050] It should be noted that, in the embodiment of the present application, the number of the hobs 5 is not limited to two groups, but no matter how many the hobs 5 are, at least two groups of hobs 5 are arranged opposite to each other.

[0051] The spacer 6 corresponds to at least one group of roller cutters 5, that is, the spacer 6 can be provided in one group corresponding to one group of roller cutters 5, or in two groups corresponding to two groups of roller cutters 5. Generally speaking, the crushing effect when the spacer 6 corresponds to two groups of roller cutters 5 is better than the crushing effect when the spacer 6 corresponds to one group of roller cutters 5, and the corresponding design can be made according to the actual crushing working conditions. For example: when the crushing device is used to crush smaller granular materials or softer materials, the crushing device can adopt the form of the spacer 6 corresponding to one group of roller cutters 5; when the crushing device is used to crush larger block materials or hard objects, the crushing device can adopt the form of the spacer 6 corresponding to two groups of roller cutters 5 to improve the crushing effect and fully crush the block materials or hard objects to the appropriate target size.

[0052] The spacers 6 are staggered with the teeth 502 of the same group of hobs 5 for engagement, and the spacers 6 extend from the sides of the teeth 502 to the bottom of the teeth 502 and form a second crushing area with the bottom of the teeth 502. When the material enters the second crushing area at the bottom after being crushed in the first crushing area, the material is brought in between the staggered spacers 6 and the teeth 502, thereby achieving secondary crushing of the material entering the second crushing area, effectively improving the crushing effect, and achieving crushing of the material to a suitable target size. In the embodiment of the present application, the spacers 6 are staggered with the teeth 502 of the same group of hobs 5, which can be understood as follows: the spacers 6 are located in the gaps between adjacent teeth 502 of the hobs 5, and the teeth 502 of the hobs 5 are located in the gaps between adjacent spacers 6. Moreover, since the spacers 6 are staggered with the teeth 502 of the same group of hobs 5, the first tooth 502 and the last spacer 6 are not in the gaps.

[0053] According to the pulverizing device of the embodiment of the present application, the teeth 502 of the two groups of roller cutters 5 are arranged in an interlaced manner to form a first pulverizing area between the two groups of roller cutters 5. When the material enters the first pulverizing area, it can be pulverized once. The spacers 6 are arranged in an interlaced manner with the teeth 502 of the roller cutters 5, and a second pulverizing area is formed between the bottom of the spacers 6 and the bottom of the teeth 502. When the material enters the second pulverizing area at the bottom after being pulverized in the first pulverizing area, it can be pulverized a second time, thereby improving the pulverizing effect and effectively pulverizing the material to a suitable target size, for example, less than 3 mm. In addition, the side of the spacers 6 can scrape the material on the teeth 502 of the roller cutters 5 to prevent the material from adhering to the teeth 502 of the roller cutters 5, thereby preventing the material from getting stuck. Therefore, the pulverizing device of the present application has the characteristics of being easy to use, having a good pulverizing effect, and having a high pulverizing efficiency.

[0054] According to one embodiment of the present application, Figure 2 and Figure 3 As shown, the spacer 6 includes a supporting portion 601 and a limiting portion 602. Along the height direction of the pulverizing device, the supporting portion 601 is located at the bottom of the tooth blades 502 of the hob 5 and engages with the tooth blades 502 of the hob 5 to form a second pulverizing area. The limiting portion 602 is connected to the supporting portion 601 and is located on the side of the tooth blades 502 and is provided with a limiting groove 603 that cooperates with the rotating shaft 501. In this embodiment of the application, the supporting portion 601 can, on the one hand, support the hob 5, and on the other hand, engage with the tooth blades 502 of the hob 5 to form a second pulverizing area, achieving secondary pulverization of the material and effectively improving the pulverizing effect. In addition, the limiting portion 602 can, on the one hand, limit the rotating shaft 501, facilitating its installation.

[0055] On the other hand, when the material enters the second crushing area at the bottom, it will be further crushed and then discharged from the bottom of the crushing device. However, at the same time, some of the crushed material may adhere to the teeth 502 of the roller 5. At this time, the limiting part 602 can also scrape off the part of the material to prevent the material from adhering to the teeth 502, thereby avoiding the phenomenon of material jamming in the roller 5.

[0056] According to one embodiment of the present application, referring to Figure 2-Figure 4As shown, two groups of spacers 6 are provided, corresponding to two groups of roller cutters 5, that is, the two groups of roller cutters 5 are each provided with a spacer 6, and the support portions 601 of the two groups of spacers 6 are arranged in a staggered manner. The support portions 601 are provided with tooth grooves 604. The blade teeth 503 of the tooth pieces 502 of the first group of roller cutters 5 engage with the tooth grooves 604 of the support portions 601 of the second group of spacers 6, and the blade teeth 503 of the tooth pieces 502 of the second group of roller cutters 5 engage with the tooth grooves 604 of the support portions 601 of the first group of spacers 6, that is, the blade teeth 502 of the two groups of roller cutters 5 cross-engage with their respective opposing spacers 6. Through the cross-engagement arrangement in this embodiment of the present application, when the material is brought to the second crushing area at the bottom, the blade teeth 503 can engage with the tooth grooves 604, which can fully crush the material and further improve the crushing effect.

[0057] According to one embodiment of the present application, Figure 3 As shown, the limiting portion 602 is in an arc shape, and the distance from the outer side surface of the limiting portion 602 on the same spacer 6 to the rotating shaft 501 is smaller than the distance from the tooth tip of the tooth 503 to the rotating shaft 501, that is, by exposing the tooth 503 of the tooth piece 502 to the outside of the limiting portion 602, the tooth 503 of the tooth piece 502 on both sides can be easily flushed by water flow to prevent material jamming, thereby improving the crushing efficiency.

[0058] According to one embodiment of the present application, Figure 3 As shown, the spacer 6 also includes a mounting portion 605, which is connected to the top of the limiting portion 602. The mounting portion 605 is provided with a first mounting hole 606, and the first mounting holes 606 of the mounting portions 605 of multiple spacers 6 are aligned axially, and are fastened by a first nut after a first fastening bolt penetrates all the first mounting holes 606; and the supporting portion 601 is provided with a second mounting hole 607, and the second mounting holes 607 of the supporting portions 601 of multiple spacers 6 are aligned axially, and are fastened by a second nut after a second fastening bolt penetrates all the second mounting holes 607.

[0059] According to one embodiment of the present application, Figure 1-Figure 3 As shown, a partition plate 7 is provided between the mounting portions 605 of each pair of adjacent spacers 6 to separate the two adjacent spacers 6. The partition plate 7 is provided with a third mounting hole 701, which is aligned with the first mounting hole 606. A first fastening bolt can be passed through all first and third mounting holes 606, 701, and then secured with a first nut. It should be understood that the mounting position of the partition plate 7 in this application should avoid interfering with the rotation of the gears 502 of the hob 5.

[0060] According to one embodiment of the present application, Figure 5As shown, the outer circumferential surface of the tooth piece 502 of the hob 5 is provided with 6-8 cutter teeth in the circumferential direction, in other words, 6-8 cutter teeth are provided on the edge of the tooth piece 502 in the circumferential direction of the tooth piece 502.

[0061] It should be noted that if the cutter teeth 503 of a single tooth piece 502 are less than 6-8, the engagement force of the hob 5 will increase, thereby increasing the driving force of the driving member (such as a motor, a motor, etc.) driving the hob 5 to rotate, and in turn the energy consumption of the driving member will be improved; if the cutter teeth 503 of a single tooth piece 502 are more than 6-8, the cutter teeth 503 on the tooth piece 502 will be more dense, and it will be difficult for large blocky materials to be engaged. Specifically, if the number of cutter teeth 503 is more than 6-8, the number of cutter teeth 503 that simultaneously contact the blocky material increases, and the blocky material is difficult to be brought into the first crushing area between the two groups of cutter teeth 503 of the hob 5, thereby resulting in ineffective crushing of the material. Therefore, by setting the cutter teeth 503 of the tooth piece 502 to 6-8, the energy consumption of the driving member can be reduced while ensuring that the material quickly enters the first crushing area to improve the crushing effect.

[0062] According to an embodiment of the present application, since the smaller the spacing between adjacent tooth pieces 502 on the same shaft 501, the greater the friction with the other group of tooth pieces 502, the driving force of the driving member (such as a motor, a motor, etc.) driving the hob 5 to rotate will increase, and in turn the energy consumption of the driving member will be improved. Therefore, the spacing between adjacent tooth pieces 502 on the same shaft 501 is set to 1.5-2.5 mm, so that the particle size of the crushed material can meet the requirements, while reducing the additional friction generated during operation, thereby reducing the energy consumption of the driving member.

[0063] According to an embodiment of the present application, as shown in Figure 5 and Figure 7 As shown, the cutter teeth 503 of the plurality of tooth pieces 502 on the same shaft 501 form a cutter tooth group in the axial direction, when the tooth piece 502 is provided with a plurality of cutter teeth 503, the corresponding cutter tooth group is also multiple groups, in each cutter tooth group, the plurality of cutter teeth 503 are staggered to form a rotational difference between the cutter teeth 503 of each adjacent two tooth pieces 502, that is, the adjacent two tooth pieces 502 have a certain deflection angle relative to the shaft 501 to make the cutter teeth 503 staggered in rotation, wherein the deflection direction of the tooth piece 502 can be clockwise or counterclockwise, that is, deflected in the same rotation direction, or the deflection direction of the tooth piece 502 can be part clockwise and part counterclockwise, that is, deflected in different rotation directions, which can be adjusted according to the actual crushing conditions. The present application can ensure that the tooth pieces 502 of the two hobs 5 fully engage the material to improve the crushing effect by setting the rotational difference of the cutter teeth 503.

[0064] In the related art, the orthographic projections of the teeth 503 of the multiple teeth 502 on the rotating shaft 501 of the cutter 5 are generally arranged to overlap in the axial direction. This causes the pressure on the cutter 5 to be concentrated on the teeth 503 in the axial direction. After crushing bulk materials or hard objects for a long time, the cutter 5 can easily be damaged. The present application provides a rotational position difference between the teeth 503, so that the pressure on the cutter 5 is distributed accordingly along the rotational position difference, that is, the pressure is dispersed along the circumference of the rotating shaft 501. Therefore, through this arrangement, the present application can disperse the pressure on the cutter body of the cutter 5, avoid excessive pressure concentration, and help protect the cutter 5, thereby extending the service life of the crushing device.

[0065] According to an embodiment of the present application, the rotational position difference between the teeth 503 of two adjacent tooth plates 502 is set to 4°-6°.

[0066] It should be noted that by setting the rotational position difference angle to 4°-6°, the present application ensures the manufacturability of the cutter body of the hob 5 while satisfying the requirements for engagement performance. Furthermore, precisely because of this cutter body structure, large-sized bulk materials or hard objects can be crushed while operating at low speeds. Furthermore, due to the low speed operation, the crushing device of the present embodiment can achieve low-noise operation.

[0067] According to one embodiment of the present application, Figure 5 and Figure 7 As shown, the teeth 503 of multiple teeth 502 on the same rotating shaft 501 are gradually offset along the axial direction at a certain deflection angle to form the rotational position difference of the above embodiment. Specifically, the rotational position difference between tooth 1 503 and tooth 2 503 is 4°-6° (e.g., 5°), and the rotational position difference between tooth 2 503 and tooth 3 503 is also 4°-6° (e.g., 5°). Similarly, a certain angle of rotational position difference is formed between adjacent teeth 503 along the same deflection direction. This ensures that the hob 5 fully engages the material and maximizes the pressure distribution effect on the hob 5, further protecting the hob 5.

[0068] According to one embodiment of the present application, the rotating shaft of the hob 5 is connected to a driving member (not shown in the figure), which drives the rotating shaft 501 to rotate and thus rotate the hob 5. The driving member is generally a motor, a motor or other device, which can drive the hob 5 to a low-noise operating state of less than 47 minutes, preventing noise and improving the user experience of the crushing device. Specifically, by adjusting the input voltage of the driving member, the speed of the driving member is reduced, and a constant voltage is set at the same time, for example, it can be 100V-120V (full load is 220V), so that the driving member can output a constant low speed, for example, it can be 90RPM-120RPM, so that compared with the full load state, the noise can be greatly reduced under low voltage and low speed conditions. In addition, if encountering a material that is difficult to crush and has a high hardness, the input voltage of the driving member can be increased in real time to meet the instantaneous high torque requirement. When the crushing is successful, the input voltage of the driving member is restored to a low voltage state. In this way, the user always feels that it is in a low noise state throughout the process.

[0069] According to one embodiment of the present application, Figures 8-10 As shown, the pulverizing device further includes a housing 3, the roller cutter 5 and the spacer 6 of the above embodiment are arranged in the housing 3, a feed port 301 is formed on the housing 3, the feed port 301 is arranged at the top of the housing 3, and the feed port 301 is connected to the first pulverizing area of ​​the roller cutter 5, a drainage channel 4 suitable for passing water is formed between the side wall of the housing 3 and the roller cutter 5, and the drainage channel 4 is connected to the feed port 301. Figure 10 The middle arrow indicates the direction of water flow. The material and part of the water flow into the first crushing area of ​​the crushing device through the feed port 301 for primary crushing, and then fall into the second crushing area at the bottom for secondary crushing. After being fully crushed, it is discharged from the bottom or discharged into the water channel in the water cup 1 described below.

[0070] In actual crushing conditions, since some of the crushed powdered material may adhere to the tooth pieces 502 of the hob 5 and not be scraped off by the spacer 6, on the one hand, it will affect the rotation of the hob 5 and thus the crushing effect, and in severe cases, the material may be stuck. On the other hand, it may breed bacteria and produce odor. Therefore, the present application sets a drainage channel 4 so that another part of the water flows through the feed port 301 and flows into the drainage channels 4 on both sides. The drainage channels 4 divert the water flow to the tooth pieces 502 on both sides of the hob 5, and flush the teeth 503. In this way, under the flushing and cleaning of the water flow, the material remaining on the teeth 503 can be easily washed away, thereby achieving self-cleaning of the tool and avoiding the material jamming and the generation of odor.

[0071] According to one embodiment of the present application, Figures 8-15As shown, a filtering device is provided between the feed inlet 301 of the pulverizing device housing 3 and the first pulverizing area. The filtering device includes a filter hopper 2, and the side wall of the filter hopper 2 is provided with a through hole 201 that communicates with the drainage channel 4. Since some material may enter the drainage channel 4 with the water flow, the embodiment of the present application provides a filter hopper 2 with a through hole in the side wall of the filter hopper 2 to filter the material, so that the material in the filter hopper 2 is concentrated and enters the first pulverizing area of ​​the roller 5, preventing the material from entering the drainage channel 4, which can further improve the self-cleaning effect.

[0072] According to one embodiment of the present application, Figure 11-13 As shown, a filter channel 202 is provided along the height of the filter hopper 2. Material and a portion of the water to be filtered flow through the inlet of the filter channel 202 into the filter channel 202 of the filter hopper 2. The material then flows through the outlet 203 at the bottom of the filter channel 202 to the first crushing area of ​​the crushing device for crushing. A through hole 201 is provided on the side wall of the filter hopper 2 and is connected to the filter channel 202. Another portion of the water to be filtered flows through the through hole 201 and flows into the drainage channel 4. The drainage channel 4 directs the water to the teeth 503 of the tooth blades 502 on both sides of the hob 5, flushing the teeth 503 and achieving self-cleaning of the cutter. The specific number of through holes 201 is not particularly limited and can be adjusted according to actual working conditions. In the embodiment of the present application, there are multiple through holes 201, and the multiple through holes 201 are provided on at least two opposite side walls of the filter hopper 2, so that water flows into the drainage channel 4 to flush the teeth 503 on both sides of the hob 5, further improving the self-cleaning effect.

[0073] The "height direction of the filter hopper 2" mentioned in the text can be understood as the direction from the inlet of the filter hopper 2 to the outlet 203. Figure 10 and Figure 13 The filter bucket 2 is placed vertically. Of course, in other usage scenarios, the filter bucket 2 can also be tilted or placed horizontally. When the filter bucket 2 is tilted or placed horizontally, the height direction of the filter bucket 2 also changes with the direction of the filter bucket 2.

[0074] In actual pulverizing conditions, when the amount of material being pulverized is large, some unpulverized material may accumulate in the filter hopper 2 above the first pulverizing zone of the roller 5. If relatively lightweight foreign matter, such as toothpicks or dental floss, is mixed into the material, it may float near the through-hole 201 of the filter hopper 2. This prevents the toothpicks or dental floss from being pulverized by the roller 5 and instead passes through the through-hole 201 of the filter hopper 2 into the drainage channel 4, causing blockage.

[0075] In order to solve the above technical problems, Figures 9-15As shown, the filter device of the present application further includes a blocking assembly, which is disposed on the outside of the filter bucket 2. The blocking assembly is located upstream in the drainage channel 4 and corresponds to the through hole 201 of the filter bucket 2. The "corresponding" mentioned here can be understood as meaning that the blocking assembly is disposed at the outlet of the through hole 201. A certain distance is provided between the blocking assembly and the outlet of the through hole 201. By disposing the blocking assembly at intervals at the outlet of the through hole 201, slender objects such as toothpicks and dental floss can be blocked without obstructing the flow of water, thereby preventing toothpicks and other slender objects from passing through the through hole 201 and entering the drainage channel 4.

[0076] In the embodiment of the present application, the blocking assembly includes a first blocking member 8 and a second blocking member 9, the first blocking member 8 and the second blocking member 9 are spaced apart, and in a plane perpendicular to the axial direction of the through hole 201, the orthographic projection of the first blocking member 8 partially overlaps with the orthographic projection of the second blocking member 9, and a water storage chamber 11 is formed between the outer side of the filter 2 and the first blocking member 8, and the water storage chamber 11 is connected to the drainage channel 4 through the gap between the first blocking member 8 and the second blocking member 9; wherein the axial direction of the through hole 201 is as shown Figure 15 The direction of the dashed line is shown.

[0077] According to an embodiment of the present application, by arranging a first blocking member 8 and a second blocking member 9 on the outside of the through hole 201 of the filter bucket 2 and upstream of the drainage channel 4, and arranging the first blocking member 8 and the second blocking member 9 at intervals so that their orthographic projections in a plane perpendicular to the axial direction of the through hole 201 partially overlap, when a slender object such as a toothpick flows into the through hole 201, the toothpick and other slender objects will be blocked by at least one of the first blocking member 8 and the second blocking member 9, or the toothpick and other slender objects may also be stuck between the first blocking member 8 and the second blocking member 9, which prevents the toothpick and other slender objects from continuing to pass through the through hole 201. In this way, the embodiment of the present application can block slender objects such as toothpicks through the blocking component set up above, preventing them from flowing through the through hole 201 to the drainage channel 4 outside the filter bucket 2, thereby avoiding water channel blockage; and at least part of the water filtered through the through hole 201 flows into the water storage chamber 11 and then flows into the drainage channel 4, and the other part of the water flows directly into the drainage channel 4. These two parts of filtered water can flow together through the drainage channel 4 to the two sides of the hob 5 for flushing. The flushed water can be directly discharged or flow into the water channel of the water cup 1 below to ensure washing water return.

[0078] It should be understood that the drainage channel 4 and the water storage chamber 11 in the embodiment of the present application are both connected to the through hole 201 of the filter bucket 2 so that the filtered water can flow into the drainage channel 4.

[0079] It should be noted that since some fine particles may flow into the through hole 201, the water storage chamber 11 is provided between the filter hopper 2 and the first blocking member 8 to collect and precipitate these particles for secondary filtration. When the water in the water storage chamber 11 spreads upward to the gap between the first blocking member 8 and the second blocking member 9, it can flow into the drainage channel 4, thereby effectively improving the filtration effect. In addition, the bottom of the water storage chamber 11 can effectively block slender objects such as toothpicks. Therefore, the embodiment of the present application achieves at least two levels of filtration through the through hole 201 and the water storage chamber 11, further ensuring the filtration effect of the filter device, thereby effectively concentrating the material in the first pulverization area of ​​the pulverization device for pulverization, and improving the self-cleaning effect of the roller.

[0080] According to one embodiment of the present application, the upper opening of the water storage chamber 11 corresponds to all the through holes 201 on the filter bucket 2, so that the water storage chamber 11 can cover all the through holes 201, that is, the water flowing out of all the through holes 201 can first pass through the sedimentation filtration of the water storage chamber 11, and then flow into the drainage channel 4, thereby further improving the filtering effect.

[0081] According to one embodiment of the present application, Figure 10 As shown, the first blocking member 8 is disposed on a side close to the filter hopper 2, and the first blocking member 8 extends from the bottom of the filter hopper 2 toward the top of the filter hopper 2. In the embodiment of the present application, the bottom of the first blocking member 8 is disposed on the top of the housing 3 of the pulverizing device to form a water storage chamber 11 between the housing 3 and the filter hopper 2. The water storage chamber 11 can filter water on the one hand, and on the other hand, the bottom of the water storage chamber 11 can prevent slender objects such as toothpicks from falling directly into the drainage channel 4.

[0082] The second blocking member 9 is arranged on the side of the first blocking member 8 facing away from the filter funnel 2 . The top of the second blocking member 9 is connected to the top of the filter funnel 2 , and the second blocking member 9 extends toward the bottom of the filter funnel 2 .

[0083] According to one embodiment of the present application, Figure 15 As shown in the figure, Ⅰ, Ⅱ, Ⅲ, Ⅳ, and Ⅴ represent slender objects such as toothpicks. Figure 15 The figure shows five angles at which slender objects such as toothpicks can be inserted into the through-hole. No matter which angle they are inserted into the through-hole, they will be blocked by the first blocking member 8 and the second blocking member 9 and cannot continue to flow out through the through-hole 201. Among them, toothpick No. 1 is inserted vertically into the through-hole 201, and toothpicks No. 2, No. 3, No. 4 and No. 5 are inserted into the through-hole 201 at an angle. When the side wall of the filter hopper 2 is a vertical surface, toothpick No. 1 cannot be inserted into the through-hole 201. Only toothpicks No. 2, No. 3, No. 4 and No. 5 at an angle can be inserted into the through-hole 201, but they will be blocked by the first blocking member 8 and the second blocking member 9 and cannot pass through the through-hole 201. When the side wall of the filter hopper 2 is as shown in FIG. Figure 12 and Figure 13When the inclined surface is shown, toothpick No. Ⅰ in the vertical direction cannot be inserted into the through hole 201. Toothpicks No. Ⅱ, No. Ⅲ, No. Ⅳ and No. Ⅴ in the inclined direction can be inserted into the through hole 201, but will also be blocked by the first blocking member 8 and the second blocking member 9 and cannot pass through the through hole 201. The specific blocking method of the blocking assembly is described below.

[0084] When a toothpick or other thin object is Figure 15 When a toothpick (size II) enters through-hole 201 at the bottom of filter funnel 2 in the direction indicated by the middle toothpick, the end of the toothpick or other slender object is blocked by first blocking member 8, i.e., the toothpick or other slender object is stuck between through-hole 201 and first blocking member 8. At the same time, because first blocking member 8 and housing 3 at the top of the pulverizing device form a water storage chamber 11, the bottom of water storage chamber 11 also blocks the toothpick. Therefore, the toothpick or other slender object cannot continue to flow through through-hole 201 of filter funnel 2 into drainage channel 4.

[0085] When a toothpick or other thin object is Figure 15 When the toothpicks No. Ⅲ and No. Ⅳ enter the through hole 201 on the upper part of the filter bucket 2 in the direction shown, the ends of the toothpicks or other slender objects will be blocked by the second blocking member 9, that is, the toothpicks or other slender objects will be stuck between the through hole 201 and the second blocking member 9 and cannot flow through the through hole 201 of the filter bucket 2 into the drainage channel 4.

[0086] When a toothpick or other thin object is Figure 15 When a toothpick (size V) enters the through-hole 201 on the upper portion of the filter hopper 2 in the direction indicated by the toothpick, the end of the toothpick or other slender object will be stuck between the first blocking member 8 and the second blocking member 9, preventing it from passing through the through-hole 201 of the filter hopper 2 and into the drainage channel 4. Therefore, by disposing the aforementioned blocking assembly outside the filter hopper 2 and upstream of the drainage channel 4, the embodiment of the present application can effectively prevent slender objects such as toothpicks from passing through the through-hole 201 from various locations.

[0087] In actual working conditions, most of the tableware contains cooking residues, which are easy to sink into the water and accumulate in the crushing device for crushing. Due to the buoyancy of toothpicks, some toothpicks are not easy to accumulate in front of the crushing device and will float above the residue. They may flow into the water path of the water cup 1 through the through hole 201 of the filter hopper 2, and then jam the washing pump and affect its operation. Due to the influence of water flow, toothpicks are generally inserted into the through hole 201 in an inclined manner for No. II, No. III, No. IV and No. V toothpicks. In the embodiment of the present application, in order to achieve the above-mentioned blocking effect, the height H2 of the second blocking member 9 is greater than the height H1 of the first blocking member 8. Specifically, the ratio of the height H2 of the second blocking member 9 to the height H1 of the first blocking member 8 is set in the range of 2.6 to 3.2. For example, the height H1 of the first blocking member 8 can be 20mm-23mm, and the height H2 of the second blocking member 9 can be 60mm-63mm. This can maximize the restriction of toothpicks and other slender objects from flowing through the through hole 201 into the waterway, and can also enable the first blocking member 8 to communicate with the water storage chamber 11 formed on the outside of the filter bucket 2 and the drainage channel 4, thereby ensuring the water flow passing through, and thus ensuring the spray washing efficiency.

[0088] According to one embodiment of the present application, Figure 15 As shown, the interval W1 between the first blocking member 8 and the second blocking member 9 ranges from 15mm to 16mm. The main consideration here is that the amount of water that can pass through meets the water volume requirement of the washing cycle. It can prevent slender objects such as toothpicks from passing through the through hole 201, and ensure the water flow space, further ensuring the efficiency of the spray washing.

[0089] It should be understood that in the embodiment of the present application, the distance between the first blocking member 8 and the through hole 201 and the distance between the second blocking member 9 and the through hole 201 should be smaller than the length of slender objects such as toothpicks, so as to better block slender objects such as toothpicks.

[0090] According to one embodiment of the present application, Figure 12 and Figure 13 As shown, the cross-sectional area of ​​the filter bucket 2 gradually decreases from the top to the bottom of the filter bucket 2, thereby making the side wall of the filter bucket 2 an inclined surface, which is convenient for collecting the residue into the first crushing area of ​​the crushing device, and can enable the water flowing out of the through hole 201 to better enter the water storage chamber 11 for sedimentation and filtration, further improving the filtering effect.

[0091] The specific shape of the filter funnel 2 of the present application is not particularly limited. In some embodiments, the shape of the filter funnel 2 can be a truncated cone or a prism.

[0092] like Figure 13 As shown, a step portion 10 is provided between the through hole 201 at the upper portion of the filter hopper 2 and the through hole 201 at the lower portion. By providing the step portion 10, it can also play a role in blocking slender objects such as toothpicks, such as Figure 15The toothpick No. Ⅰ vertically inserted into the through hole 201 is directly inserted into the step portion 10 and cannot enter the through hole 201.

[0093] According to one embodiment of the present application, Figure 11 As shown, the length-to-width ratio of the bottom discharge port 203 of the filter bucket 2 ranges from 1.1 to 1.3. For example, the length L of the bottom discharge port 203 of the filter bucket 2 is 70mm-72mm, and the width W2 is 59mm-62mm. By setting the size of the bottom discharge port 203 of the filter bucket 2, it can be effectively ensured that the material falls into the first crushing area of ​​the crushing device.

[0094] According to one embodiment of the present application, Figure 11 As shown, the filter funnel 2 has multiple through-holes 201 spaced apart. From the top to the bottom of the filter funnel 2, the distance F between two adjacent through-holes 201 ranges from 7 mm to 8 mm, and the ratio of the width to the height of the through-holes 201 ranges from 1.1 to 1.6. For example, the width W3 of the through-holes 201 ranges from 7 mm to 8 mm, and the height H3 of the through-holes 201 ranges from 5 mm to 6 mm. Because toothpicks are sufficiently shredded, their size is within 5 mm, allowing them to enter the through-holes 201 of the filter funnel 2. By adjusting the size of the through-holes 201, the present application can effectively prevent unshredded toothpicks from entering while appropriately allowing shredded toothpicks to enter.

[0095] According to one embodiment of the present application, the center hole distance between two adjacent through holes 201 perpendicular to the height direction of the filter funnel 2 is 8 mm to 9 mm, which can effectively prevent uncrushed toothpicks from entering.

[0096] According to one embodiment of the present application, at least one row of through holes 201 is provided along the height direction of the filter bucket 2. In this example, the through holes 201 are provided in two rows to improve the filtering effect.

[0097] According to one embodiment of the present application, a plurality of through holes 201 are provided on at least two opposite side walls of the filter bucket 2 to improve water return and filtration efficiency.

[0098] According to one embodiment of the present application, Figure 14 As shown, the first blocking member 8 and the second blocking member 9 may be baffles that block all through holes 201 along the height direction of the filter funnel 2 .

[0099] On the other hand, the dishwasher of the second embodiment of the present application mainly includes: an inner tank (not shown in the figure), a water cup 1, a filtering device and a crushing device. A tableware rack is provided at the upper part of the inner tank to place tableware, and a water cup 1 is provided at the bottom of the inner tank. A water path is provided in the water cup 1, and the water path is connected to the drainage channel 4. A spray arm and a washing pump connected to the water path are provided on the water cup 1. The washing pump sends water in the water path to the spray arm, and then sprays and rinses the tableware.

[0100] like Figures 8-10 As shown, the crushing device is disposed within the water cup 1 and is located below the feed inlet of the water cup 1. The filtering device is disposed between the feed inlet of the water cup 1 and the crushing device. Specifically, the inlet of the filter channel 202 of the filter hopper 2 of the filtering device is connected to the feed inlet of the water cup 1, and the discharge port 203 of the filter channel 202 extends to the first crushing area above the crushing device within the water cup 1. Dishwasher residue and water to be filtered enter the filter hopper 2 through the feed inlet of the water cup 1. The filter hopper 2 can effectively collect dishwasher residue in the first crushing area of ​​the crushing device for crushing. On the other hand, the water to be filtered can be filtered through the through hole 201 of the filter hopper 2, flow into the drainage channel 4, flush the roller 5, and then flow into the water channel within the water cup 1, ensuring water return to facilitate the dishwasher's circulation spray flushing.

[0101] In one embodiment of the present application, Figure 10 As shown, the arrows represent water flow. The residue and the water to be filtered flow into the filter hopper 2 through the feed port of the water cup 1, and then enter the first crushing area of ​​the roller 5 and are crushed. Since the cutting speed of the roller 5 is not that fast, when there is too much residue to be crushed, it will accumulate above the roller 5. At this time, lighter objects (mainly slender objects such as toothpicks) will float near the through hole 201 of the filter hopper 2, and then flow into the through hole 201 of the filter hopper 2 and be blocked by the blocking component, and part of the water flow will also flow into the through hole 201; large-volume block residue cannot enter the through hole 201, but continues to sink towards the roller 5 under the action of gravity. Some fine particle residue may flow through the through hole 201 and then further enter the water storage chamber 11 for sedimentation and filtration. The filtered water flushes the roller 5 through the drainage channel 4 and enters the water path of the water cup 1, and is then pumped into the washing pump for spray washing. Therefore, the present application can not only ensure the crushing of residue, but also ensure that the water in the dishwasher remains circulated.

[0102] In one embodiment of the present application, a filter is provided between the water channel of the water cup 1 and the washing pump to further filter the water used to flush the roller 5 before being pumped into the washing pump to ensure the washing effect, and the filtered residue is discharged through the water channel after washing is completed.

[0103] According to the dishwasher of the embodiment of the present application, the filter 2 is arranged between the water cup 1 and the hob 5, so that the residual of the dishwasher can be effectively collected to the first crushing area of the hob 5 for crushing. Meanwhile, the blocking assembly is arranged outside the through hole 201 of the filter 2, so that the toothpick and other slender objects can be blocked to prevent them from flowing into the water path of the water cup 1 through the through hole 201, thereby avoiding the water path from being blocked and ensuring the normal operation of the dishwasher. The water filtered through the through hole 201 flows into the drainage channel 4 at least partially after flowing into the water storage cavity 11, and the other part of the water directly flows into the drainage channel 4. The two parts of the water filtered through the through hole 201 flow through the drainage channel 4 and can flow together to the two sides of the hob 5 for flushing and washing, so as to realize the self-cleaning of the hob. The flushed water and the crushed residual fall into the water path of the water cup 1, and the crushed residual is further filtered through the filter screen in the water path. The filtered water is pumped into the spray arm through the washing pump for spraying, so as to realize the circulating spray washing of the dishwasher. Therefore, the dishwasher of the embodiment of the present application can automatically process the residual, crush the residual of the dishwasher to a dischargeable size, avoid affecting the water path circulating spray in the water cup, prevent the water path in the dishwasher from being blocked, solve the problem of manually processing the residual in the related art, and realize the maintenance-free function of the dishwasher.
