Description

Technical Field

[0001] This utility model relates to the field of water pipe drainage technology, and in particular to an anti-clogging filter device for water pipes. Background Technology

[0002] Water pipes are pipes that supply water. In modern renovations, water pipes are usually installed by embedding them in the wall. There are three types of water pipes: the first type is metal pipes, such as hot-dip galvanized cast iron pipes with inner plastic lining; the second type is plastic-coated metal pipes, such as steel-plastic composite pipes; and the third type is plastic pipes, such as PB pipes. To prevent foreign objects from entering the pipes, barriers such as grilles are usually installed at the water inlet to avoid blockages caused by foreign objects.

[0003] In existing technologies, to address the problem of water pipes being easily clogged by household waste, users typically install filters at the drain outlet to intercept the waste. However, in actual use, to ensure the interception effect, the filter holes are usually small in diameter. When intercepting larger pieces of household waste, the filter is easily clogged, preventing sewage from being discharged in a timely manner. Users then have to manually clean the sewage. Furthermore, the household waste stored inside the filter is inconvenient to remove during cleaning, which presents significant limitations. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technology where the filter screens used to ensure interception effect are usually small in diameter, and the filter screens are easily clogged when intercepting some large household waste, resulting in sewage not being discharged in time and requiring users to clean them manually in the sewage. In addition, the household waste stored in the filter screen is inconvenient to remove during cleaning, which has great limitations. Therefore, this utility model proposes an anti-clogging filter device for water pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water pipe anti-clogging filter device, comprising a drain pipe, a filter being snapped into the middle of the drain pipe, the filter comprising a fixed plate, a diverter screen, and a fixed cylinder, a slot being provided on the outer side of the upper middle part of the fixed plate, the diverter screen being inserted into the fixed plate through the slot, the fixed cylinder being fixedly installed at the lower end of the fixed plate, a slot 1 being provided on both sides of the fixed cylinder, a movable cylinder being snapped into the fixed cylinder, a locking block being fixedly installed at the upper end of the movable cylinder, a sliding groove being provided on one side of the fixed plate, the locking block being slidably snapped into the sliding groove, a slot 2 being provided on both sides of the movable cylinder, the slot 2 being engaging with the slot 1, a filter screen being snapped into the middle of the lower end of the fixed cylinder and the movable cylinder, a fixed rod being fixedly installed at the middle of the upper part of the filter screen, and multiple blocking rods being evenly fixedly installed on the surface of the fixed rod.

[0006] Preferably, the plurality of the barrier bars are arranged in a spiral, and the surface of the diversion net is uniformly provided with a plurality of drainage channels.

[0007] Preferably, a baffle is fixedly installed at the middle of the lower end of both the fixed cylinder and the movable cylinder, and the filter screen is located above the baffle.

[0008] Preferably, a pull rod is rotatably mounted on the outer side of the middle part of the fixing plate.

[0009] Preferably, the drain pipe has a drain outlet in the middle, and the filter is snapped into the middle of the drain outlet.

[0010] Preferably, the lower end of the drain pipe is connected to a drain pipe.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting up a diversion net higher than the drain outlet, wastewater mixed with domestic waste is poured into the pool and discharged during use. The drain opening of the diversion net is large, so it will not be blocked by large garbage and thus affect the drainage rate. Smaller garbage and wastewater will enter the middle of the fixed cylinder and the movable cylinder together. A filter screen that can block garbage and wastewater is set at the bottom of the fixed cylinder and the movable cylinder. Above, there are spirally fixed barrier bars that are evenly arranged along the fixed rod. The barrier bars can form an effective physical barrier when the water flows through and increase the contact area with garbage in the water flow. Most garbage will be intercepted by multiple barrier bars, and when the water flow encounters the barrier bars, it will be forced to change direction. This flow method helps to attach garbage to the barrier bars, thereby further reducing the possibility of garbage clogging the filter screen.

[0013] 2. In this utility model, by setting a pull rod on one side of the fixed plate, when the filter needs to be cleaned of domestic waste after a period of use, simply move the pull rod to a position perpendicular to the filter and then pull it up to remove the filter. Then, remove the movable cylinder along the slide groove, and then remove the filter screen and the components above it, making it convenient for users to clean the waste inside.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-5 As shown, this utility model provides a water pipe anti-clogging filter device, including a drain pipe 1, a filter 2 snapped into the middle of the drain pipe 1, the filter 2 including a fixing plate 21, a diverter net 23 and a fixing cylinder 25, a slot 22 is opened on the outer side of the upper middle part of the fixing plate 21, the diverter net 23 is inserted into the fixing plate 21 through the slot 22, the fixing cylinder 25 is fixedly installed on the lower end of the fixing plate 21, and a slot 26 is opened on both sides of the fixing cylinder 25, the fixing cylinder 25 is snapped into a movable cylinder 2. 8. A locking block 29 is fixedly installed at the upper end of the movable cylinder 28. A sliding groove 27 is provided on one side of the fixed plate 21. The locking block 29 and the sliding groove 27 are slidably engaged. A second locking groove 30 is provided on both sides of the movable cylinder 28. The second locking groove 30 is engaged with the first locking groove 26. A filter screen 32 is engaged between the middle of the lower end of the fixed cylinder 25 and the movable cylinder 28. A fixing rod 33 is fixedly installed at the middle of the upper end of the filter screen 32. Multiple blocking rods 34 are evenly fixedly installed on the surface of the fixing rod 33.

[0023] The specific settings and functions of this embodiment are described below. The diversion net 23 is higher than the drain outlet 12, which can increase the speed at which water enters the drain pipe 11 through the drain trough 24. In use, wastewater mixed with domestic waste is poured into the pool and discharged through the drain pipe 1. The drain trough 24 of the diversion net 23 has a large opening, so it will not be blocked by large garbage and thus affect the drainage rate. Smaller garbage and wastewater will enter the middle of the fixed cylinder 25 and the movable cylinder 28 together. At the bottom of the fixed cylinder 25 and the movable cylinder 28, there is a filter net 32 ​​that can block garbage and wastewater. Above it, there are spirally fixed blocking bars 34 that are evenly arranged along the fixed rod 33. The blocking bars 34 can form an effective physical barrier when the water flows through and increase the contact area with garbage in the water. Most garbage will be blocked by multiple blocking bars 34, and when the water flows into the blocking bars 34, it will be forced to change direction. This flow method helps to attach garbage to the blocking bars 34, thereby further reducing the possibility of garbage clogging the filter net 32.

[0024] Example 2, as Figure 1 , Figure 2 and Figure 3 As shown, multiple barrier bars 34 are arranged in a spiral pattern, multiple drainage channels 24 are evenly distributed on the surface of the diversion net 23, baffles 31 are fixedly installed at the middle of the lower end of the fixed cylinder 25 and the movable cylinder 28, the filter screen 32 is located above the baffles 31, a pull rod 35 is rotatably installed on the outer side of the middle of the fixed plate 21, a drain outlet 12 is opened in the middle of the drain pipe 1, the filter 2 is snapped into the middle of the drain outlet 12, and a drain pipe 11 is connected through the lower end of the drain pipe 1.

[0025] The overall effect of this embodiment is that the diversion net 23 is higher than the drain outlet 12, which increases the speed at which water enters the drain pipe 11 through the drain trough 24. During use, wastewater mixed with household waste is poured into the pool and discharged through the drain pipe 1. The drain trough 24 of the diversion net 23 has a large opening, preventing large debris from clogging the drainage rate. Smaller debris and wastewater enter the middle of the fixed cylinder 25 and the movable cylinder 28 together. A filter screen 32 is provided at the bottom of the fixed cylinder 25 and the movable cylinder 28 to block debris and wastewater. Above, spirally fixed blocking rods 34 are evenly arranged along the fixed rod 33. The blocking rods 34 can prevent water from flowing through... This forms an effective physical barrier and increases the contact area with garbage in the water flow. Most of the garbage will be intercepted by multiple barrier bars 34, and when the water flow encounters the barrier bars 34, it will be forced to change direction. This flow pattern helps to attach the garbage to the barrier bars 34, thereby further reducing the possibility of garbage clogging the filter screen 32. When the filter 2 needs to be cleaned of domestic waste after a period of use, simply move the lever 35 to a position perpendicular to the filter 2, and then pull it upward to remove the filter 2. Then, remove the movable cylinder 28 along the slide groove 27, and then remove the filter screen 32 and the components above it, making it convenient for users to clean the garbage inside.

[0026] The usage and working principle of this device: The height of the diversion net 23 is higher than that of the drain outlet 12. When wastewater mixed with domestic waste is poured into the pool and discharged through the drain pipe 11, due to the large opening and height of the drain trough 24 of the diversion net 23, more water will directly enter the middle of the filter 2 through the drain trough 24, and will not be blocked by large garbage, thus affecting the drainage rate. Smaller garbage and wastewater will enter the middle of the fixed cylinder 25 and the movable cylinder 28 together. The bottom of the fixed cylinder 25 and the movable cylinder 28 is equipped with a filter screen 32 that can block garbage and wastewater. Above, there are spirally fixed blocking rods 34 evenly arranged along the fixed rod 33. The blocking rods 34 can block garbage and wastewater. As water flows through, it forms an effective physical barrier, increasing the contact area with garbage in the water. Most of the garbage will be intercepted by multiple barrier bars 34, and when the water flows into the barrier bars 34, it will be forced to change direction. This flow pattern helps to attach garbage to the barrier bars 34, thereby further reducing the possibility of garbage clogging the filter screen 32. When the filter 2 needs to be cleaned of domestic waste after a period of use, simply move the lever 35 to a position perpendicular to the filter 2, and then pull it upward to remove the filter 2. Then, remove the movable cylinder 28 along the slide groove 27, and then remove the filter screen 32 and the components above it, making it convenient for users to clean the garbage inside.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
