Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning equipment such as shoe sole cleaning machines, and specifically relates to a drainage component and a cleaning machine having the same. Background Technology

[0002] A shoe sole cleaning machine is a cleaning device used to clean shoe soles. It is widely used in cleanrooms, laboratories and other places with high environmental requirements, such as bioengineering, pharmaceuticals or food processing. It automatically cleans shoe soles by rolling brushes to apply cleaning water, and then dries the soles with an absorbent blanket to prevent outdoor dust and dirt from being brought indoors.

[0003] An existing technology, disclosed in CN118402740A, discloses an automatic intelligent lift-up shoe sole cleaning machine, comprising a frame, a fixed support inside the frame, a cleaning mechanism inside the fixed support, a water inlet pipe extending through the bottom of the inner side of the frame, a drainage trough at the bottom of the inner side of the frame, and a filter plate at the top of the drainage trough, with the upper surface of the filter plate flush with the lower surface of the scraper. As shown in the attached figure, the filter plate is planar. During prolonged use of this cleaning machine, dust and other debris from cleaning shoe soles accumulate on the upper surface of the filter plate, turning into dirt, which eventually clogs all the filter holes on the filter plate. The inability to drain water leads to overflow issues, requiring the removal of accumulated dirt from the filter plate before reuse. This results in a short maintenance cycle for the cleaning machine, necessitating frequent cleaning of the filter plate and increasing the user's workload. Secondly, the filter plate structure itself presents challenges in actual maintenance. Because the filter plate continuously filters the water inside the machine, it cannot be directly removed during use. Instead, the dirt must be painstakingly removed bit by bit using hands or other external tools (such as a shovel), a cumbersome and inconvenient method for manual cleaning. Utility Model Content

[0004] The purpose of this utility model is to overcome the existing technical defects and provide a drainage component that can prevent all filter holes from being blocked at the same time during long-term use, thereby extending the maintenance time of the equipment.

[0005] In a first aspect, in order to solve the above-mentioned technical problems, the present invention provides a drainage component, including a first filter element with a drainage cavity formed at the bottom. The first filter element includes a first filter part and a second filter part that is hollow and protrudes from the middle of the first filter part. The bottom of the second filter part is an opening. The surface of the first filter part is provided with a plurality of first filter holes communicating with the drainage cavity. The side of the second filter part is provided with a plurality of second filter holes communicating with the drainage cavity.

[0006] Furthermore, the top surface of the second filter section is also provided with a plurality of second filter holes that communicate with the drainage cavity.

[0007] Furthermore, the second filter section is a trapezoid with a smaller top and a larger bottom, so that all sides of the second filter section are inclined surfaces.

[0008] Furthermore, the first filter section has supporting edges bent downwards on all four sides, so that the first filter section and the second filter section are suspended in the air, and a drainage cavity communicating with the first filter hole and the second filter hole is formed at the bottom of the first filter element.

[0009] Furthermore, the bottom of the first filter section is provided with a plurality of support feet, the bottom of which is flush with the bottom of the support edge.

[0010] Furthermore, the first filter section is provided with multiple countersunk screw holes for screws to pass through.

[0011] Furthermore, the drainage component also includes a second filter element movably mounted on the upper part of the first filter element. The second filter element includes a third filter element covering the first filter element and a fourth filter element protruding from the middle of the third filter element and mounted on the outer periphery of the second filter element. The third filter element has a third filter hole through it at the position corresponding to each first filter hole, and the fourth filter element has a fourth filter hole through it at the position corresponding to each second filter hole. The third filter element has a baffle bent upwards around its perimeter, with a height lower than that of the fourth filter element, so as to form a filter cavity for accommodating filter residue between the baffle, the third filter element and the fourth filter element.

[0012] Furthermore, a handle is provided at the top of the fourth filter section.

[0013] Secondly, this utility model also provides a cleaning machine, including a drainage component as described in any of the first aspects.

[0014] Furthermore, the bottom of the cleaning machine is recessed with a water collection trough, and the drainage component is suspended in the water collection trough.

[0015] Furthermore, the first filter element is fixed to the water collection tank by screws.

[0016] This utility model has the following beneficial effects: Firstly, in this invention, a raised and hollow second filter section is designed in the middle of the horizontal first filter section. Both the first and second filter sections are provided with filter holes. When this first filter element is applied to cleaning equipment such as shoe sole cleaning machines to filter sewage, dust and other debris in the sewage will continuously accumulate on the first filter section, eventually clogging all the first filter holes. However, because the second filter section is higher than the first filter section, the second filter holes on the second filter section will not be clogged by the mud deposited at the bottom. At this time, sewage can be discharged outward through the second filter holes. Furthermore, the side drainage method of the second filter section also reduces the possibility of clogging by deposited mud, unless the height of the deposited mud and debris exceeds the height of the entire second filter section. Thus, during long-term use of the equipment, all filter holes can be prevented from being clogged at the same time, extending the maintenance time of the equipment and reducing the workload of personnel in equipment maintenance. Moreover, the method of setting filter holes on all four sides can effectively increase the number of filter holes compared to the existing method of setting filter holes on a single horizontal plane, thereby increasing the drainage volume.

[0017] Secondly, the addition of a second filter element allows dirt and debris to settle in the upper filter chamber. During equipment maintenance and cleaning, simply remove the second filter element, empty the debris, and clean it. This facilitates the maintenance and cleaning of the equipment's drainage trough. After the second filter element is removed, the first filter element continues to filter and drain the water entering the equipment, preventing debris from entering the water pump and causing damage. The first filter element does not accumulate dirt for a short period after the second filter element is removed, cleaned, and then reinstalled, thus not affecting the continuous long-term use of the drainage component. The handle on the second filter element makes it easy to remove.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0020] To better understand the technical content of this utility model, the following will further introduce and explain this utility model in conjunction with the accompanying drawings and specific embodiments. It should be noted that if there are descriptions such as "first" and "second" in the text, they are used to distinguish different components, etc., and do not represent the order of priority, nor do they limit "first" and "second" to be different types.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1 like Figures 1 to 2 As shown in the figure, the drainage component shown in this embodiment includes a first filter element 1. The bottom of the first filter element 1 forms a drainage cavity 10. The first filter element 1 includes a first filter part 11 with a flat surface and a second filter part 12 that is hollow and protrudes from the middle of the first filter part 11, so that the whole first filter element 1 forms a structure with flat sides and a protruding middle. The bottom of the second filter part 12 is open. The surface of the first filter part 11 is provided with a plurality of first filter holes 13 that communicate with the drainage cavity 10. The side of the second filter part 12 is provided with a plurality of second filter holes 14 that communicate with the drainage cavity 10. That is, when the first filter element is used, the water at its upper end can flow down to the drainage cavity 10 at the bottom through the first filter holes 13 and the second filter holes 14.

[0023] In the above structure, a raised and hollow second filter section is designed in the middle of the horizontal first filter section. Both the first and second filter sections are provided with filter holes. When the first filter element is applied to cleaning equipment such as shoe sole cleaning machines to filter sewage, dust and other debris in the sewage will continuously accumulate on the first filter section, eventually clogging all the first filter holes. However, because the second filter section is higher than the first filter section, the second filter holes on the second filter section will not be clogged by the mud deposited at the bottom. At this time, sewage can be discharged outward through the second filter holes. The side drainage method of the second filter section also reduces the possibility of clogging by the deposited mud, unless the height of the deposited mud and debris exceeds the height of the entire second filter section. Thus, during long-term use of the equipment, all filter holes can be prevented from being clogged at the same time, extending the maintenance time of the equipment and reducing the workload of personnel in equipment maintenance. Moreover, the method of setting filter holes on all four sides can effectively increase the number of filter holes compared to the existing method of setting filter holes on a single horizontal plane, thereby increasing the drainage volume.

[0024] In one embodiment, such as Figures 1 to 2 As shown, in order to form a drainage cavity at the bottom of the first filter element, the first filter part 11 is provided with support edges 15 that are bent downwards on all four sides. Through the surrounding effect of the support edges 15, a drainage cavity 10 communicating with the first filter hole 13 and the second filter hole 14 is formed at the bottom of the first filter element 1. When it is applied in the water collection tank of the cleaning equipment, the support edges 15 are used to support the entire first filter element 1, so that the first filter part 11 and the second filter part 12 are suspended in the air, ensuring that the wastewater in the cleaning equipment can fall into the drainage cavity below after being filtered by the first filter element. The water pump on the cleaning equipment then discharges the water in the drainage cavity outwards.

[0025] Of course, in some specific implementation cases, it is not necessary to set up supporting edges around the first filter section. The water collection tank of the cleaning equipment can be designed as a stepped trough structure with a larger top and a smaller bottom. In this way, the first filter element is placed in the upper large trough, so that the filtered water falls into the lower small trough. Alternatively, several supporting feet can be set at the bottom of the first filter section, so that the first filter element is suspended in the water collection tank to achieve its filtering and drainage functions.

[0026] In one embodiment, such as Figures 1 to 2 As shown, the bottom of the first filter section 11 is also provided with a plurality of support feet 16. The bottom of the support feet 16 is flush with the bottom of the support edge 15, which plays a supporting role at various positions of the first filter section 11, and avoids the problem of downward bending and deformation due to gravity after the soil is deposited on the upper side of the first filter section.

[0027] In one embodiment, such as Figures 1 to 2As shown, the top surface of the second filter section 12 is also provided with several second filter holes 14 that communicate with the drain chamber 10, which further increases the drainage volume and avoids the problem of filter holes being blocked.

[0028] In one embodiment, such as Figures 1 to 2 As shown, the second filter section 12 is a trapezoid with a smaller top and a larger bottom, so that all sides of the second filter section 12 are inclined surfaces. This allows water to be easily concentrated on the sides of the second filter section when it is used in cleaning equipment, making it easy to drain water outwards.

[0029] In another embodiment, such as Figures 1 to 2 As shown, the first filter section 11 is also provided with a plurality of countersunk screw holes 17 for screws to pass through, for fixing the first filter element to the cleaning equipment by screws.

[0030] Understandably, in other implementation cases, the first filter element can also be fixed to the cleaning equipment by welding.

[0031] Understandably, in actual use, the first filter element can be placed directly in the water collection tank of the cleaning equipment without using screws, making it easy to remove. In this case, the threaded hole can also be used as a filter hole.

[0032] In other embodiments, the first filter element is manufactured in a one-piece molding process.

[0033] Example 2 like Figures 1 to 6 As shown, the drainage component 100 shown in this embodiment, based on the structure described in Embodiment 1, further includes a second filter component 2 movably mounted on the upper part of the first filter component 1. The second filter component 2 includes a third filter component 21 stacked and covering the first filter component 11, and a fourth filter component 22 protruding from the middle of the third filter component 21 and mounted on the outer periphery of the second filter component 12. The third filter component 21 has a third filter hole 23 penetrating at the position corresponding to each first filter hole 13, and the fourth filter component 22 has a fourth filter hole 24 penetrating at the position corresponding to each second filter hole 14. Thus, when this drainage component is applied to a cleaning device, the cleaning wastewater flows downward to the drainage chamber after passing through the third filter hole 23, the first filter hole 13, the fourth filter hole 24, and the second filter hole 14 in sequence.

[0034] In this embodiment, as Figures 3 to 6As shown, the third filter section 21 has vertically bent edges 25 on all four sides, with a height lower than that of the fourth filter section 22, forming a filter chamber 26 for accommodating filter residue between the edges 25, the third filter section 21, and the fourth filter section 22. This second filter element allows dirt and debris to settle in the upper filter chamber. During equipment maintenance and cleaning, simply remove the second filter element, empty the debris, and clean it. This facilitates the maintenance and cleaning of the equipment's drainage system. After the second filter element is removed, the first filter element continues to filter and drain the incoming water, preventing debris from entering the water pump and causing damage. The first filter element does not accumulate dirt for a short period after the second filter element is removed, cleaned, and then reinstalled, thus not affecting the long-term use of the drainage component.

[0035] In this embodiment, as Figures 3 to 6 As shown, the top of the fourth filter section 22 is provided with a handle 27, which makes it easy to remove the second filter element for cleaning.

[0036] In one embodiment, such as Figures 3 to 6 As shown, the surface of the third filter section 21 is provided with reinforcing ribs 28 to strengthen the strength of the third filter section 21 and prevent the third filter section 21 from bending and deforming downwards due to gravity after the soil is deposited on the upper side.

[0037] In another embodiment, such as Figures 3 to 6 As shown, a fifth filter hole 29 is provided on at least one side of the retaining edge 25 for discharging water from the filter chamber 26 when the second filter element is lifted.

[0038] In other embodiments, the second filter element is manufactured in a one-piece molding process.

[0039] In other embodiments, the second filter element, except for the handle, is manufactured in one piece. Example 3 like Figures 7-10 As shown, the cleaning machine described in this embodiment includes a drainage component 100 as described in Embodiment 1 or Embodiment 2.

[0040] Specifically, a water collection tank 200 is recessed at the bottom inner side of the cleaning machine, and a drainage component 100 is suspended in the water collection tank 200 by a support side and a support foot, so that the water filtered by the drainage component 100 can fall downward into the drainage chamber 10 at the bottom.

[0041] In one embodiment, the first filter element 1 is fixed in the water collection tank 200 by screws to prevent the user from removing the first filter element during maintenance and cleaning, which would cause dirt and other debris in the wastewater to enter the water pump of the cleaning equipment and damage the water pump.

[0042] In one embodiment, such as Figure 10 As shown, a drain outlet 203 connected to the drain chamber 10 is provided on one side of the water collection tank. The drain outlet is connected to a water pump (not shown in the figure) through a pipe 201 and is used to pump out wastewater.

[0043] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
