DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0036] The core of the present application is to provide a U-shaped grid filtering device which can guarantee sewage purification effect and effectively reduce the risk of impurities flowing back into the fish tank from the water inlet. Another core of the present application is to provide a U-shaped grid filtering device.

[0037] Please refer to Figures 1-7 .

[0038] The present embodiment provides a U-shaped grid filtering device, which comprises:

[0039] The front shell 1 is provided with a water inlet 11 at the bottom, and a plurality of rows of U-shaped groove structures 12 are arranged on the inner side of the front shell 1 in a spaced-apart manner. The U-shaped groove structures 12 in the same row are distributed in a spaced-apart manner to form a flow channel 4. The U-shaped groove structure 12 is used to accommodate the deposited impurities.

[0040] The rear shell 2 is used to be connected with the front shell 1 to form an accommodation cavity, and the bottom of the rear shell 2 is provided with a water outlet 21.

[0041] The filtering element 3 is arranged in the accommodation cavity.

[0042] The water pumping device is used to drive the impurity sewage to flow from the water inlet 11, pass through the flow channel 4 and pass through the filtering element 3, and then flow out from the water outlet 21.

[0043] It should be noted that the water pumping device can be set as a water pump to drive the sewage to flow. Moreover, the inner side of the front shell 1 refers to the side of the front shell 1 close to the accommodation cavity, and the inner side of the rear shell 2 also refers to the side of the rear shell 2 close to the accommodation cavity. The inner side of the front shell 1 is provided with a plurality of rows of U-shaped groove structures 12 in a spaced-apart manner, which means that the U-shaped structure ribs are extended on the plane plate of the front shell 1. The length direction of the U-shaped structure rib is parallel to the length direction of the front shell 1. When the impurity sewage flows from bottom to top, the impurities blocked by the filtering element 3 and the impurities deposited during the flow process can be carried and accommodated by the U-shaped structure rib.

[0044] In actual application process, the shape, structure, size, material, position, etc. of the front shell 1, the rear shell 2, the filtering element 3 and the water pumping device can be determined according to actual situation and actual demand.

[0045] When the U-shaped grid filter device is used, under the action force of the water pumping device (for example, a water pump), the impurity sewage flows into the containing cavity from the water inlet 11 of the front shell body 1, and the impurity sewage flows through the flow channel 4 of the front shell body 1 towards the rear shell body 2. In the flowing process, the impurity sewage is purified by passing through the filter piece 3, that is, the water can flow out through the filter piece 3, and the impurities are blocked by the filter piece 3. Finally, the purified water flows out from the water outlet 21 of the rear shell body 2, so as to realize the purification operation of the impurity sewage.

[0046] Moreover, since the U-shaped groove structure 12 is arranged on the inner side of the front shell body 1, the U-shaped groove structure 12 can not only effectively support the filter piece 3, but also effectively intercept the impurities in the sewage, that is, when the sewage flows through the flow channel 4, the impurities will be left in the U-shaped groove structure 12 under the action of gravity, each U-shaped groove structure 12 has the effect of accumulating and depositing impurities, and the risk of the impurities flowing back into the water tank from the water inlet 11 can be effectively reduced.

[0047] In summary, the U-shaped grid filter device provided by the utility model can not only guarantee the sewage purification effect, but also effectively reduce the risk of the impurities flowing back into the fish tank from the water inlet.

[0048] In one embodiment, as shown in Figure 2 The inner side of the rear shell body 2 is provided with a plurality of rows of structure ribs 22 which are distributed in an up-down interval, and the structure ribs 22 are used for supporting the filter piece 3. The structure ribs 22 and the U-shaped groove structure 12 can clamp and fix the filter piece 3, so as to avoid the position of the filter piece 3 moving in the use process and affecting the filtering effect of the filter piece 3.

[0049] In one embodiment, as shown in Figure 2 The structure rib 22 is an L-shaped structure which is horizontally arranged at the inner side corner of the rear shell body 2, and two L-shaped structures in the same row are oppositely distributed. By arranging the L-shaped structure of the structure rib 22, the fixing effect of the filter piece 3 can be effectively improved. Moreover, a vertical partition plate can be arranged on the inner side of the rear shell body 2, so as to ensure that the filter piece 3 is clamped and fixed at each position and does not appear the position deviation phenomenon in the use process. The rear shell body 2 is arranged in this way, so that the structure rib 22 of the rear shell body 2 contacts the filter piece 3, a water flow space is reserved, and the purified water flow can flow out from the water outlet 21 of the rear shell body 2.

[0050] In one embodiment, the filter piece 3 includes filter cotton, gauze or filter cloth.

[0051] It should be noted that the filter 3 is the core component of the water filter, responsible for intercepting impurities in sewage. The filter 3 can use high-strength wedge-shaped filter screens with high filtering precision and long service life. The material of the filter 3 is diverse, including stainless steel, polypropylene, polyester, etc., and the specific selection depends on the filtering requirements and fluid properties. That is, in actual application, the type of filter 3 can be determined according to actual conditions and actual needs.

[0052] In one embodiment, as shown in Figure 2 The water inlet 11 includes a first water inlet 13 and a second water inlet 14 arranged on the bottom of the front shell 1, and the second water inlet 14 is arranged above the first water inlet 13 to accommodate more impurities in the sewage at the same time.

[0053] In one embodiment, as shown in Figure 1 , Figure 4 and Figure 5 The inner bottom of the front shell 1 is provided with a first U-shaped sedimentation groove 15 and a second U-shaped sedimentation groove 16 spaced apart from the first U-shaped sedimentation groove 15, and the first U-shaped sedimentation groove 15 is arranged on the top of the first water inlet 13, and the second U-shaped sedimentation groove 16 is arranged on the top of the second water inlet 14, and the first U-shaped sedimentation groove 15 and the second U-shaped sedimentation groove 16 are staggered.

[0054] For example, three first U-shaped sedimentation grooves 15 can be arranged on the inner bottom of the front shell 1, and the bottom of each first U-shaped sedimentation groove 15 is arranged on the top of the first water inlet 13, and two second U-shaped sedimentation grooves 16 are arranged on the inner bottom of the front shell 1, and the bottom of each second U-shaped sedimentation groove 16 is arranged on the top of the second water inlet 14, and the first U-shaped sedimentation groove 15 and the second U-shaped sedimentation groove 16 are staggered, so that the flow trajectory of the sewage is more tortuous, which helps more impurities in the sewage to be deposited freely.

[0055] As shown in Figure 5 The impurity sewage enters from the five water inlets on the bottom of the front shell 1 and the oil film inlet 17 on the top, and under the action of the water pumping device, the impurity sewage can flow along the flow channel 4 in the direction of the arrow, and under the blocking action of the filter 3, the sewage passes through the filter 3, and the impurities are blocked in the U-shaped groove structure 12 of the front shell 1. The U-shaped groove structure 12 deposits impurities, and the flow channel 4 will not be blocked due to the impact of the water flow, forming a vertically placed filter 3 that effectively filters sewage.

[0056] When the impurity sewage flows into the containing cavity from the first water inlet 13 and the second water inlet 14, the sewage flows under the action of the water pumping device (such as a water pump), and the sewage can flow from bottom to top through the flow channel 4, and when the sewage flows through the first U-shaped deposition groove 15 and the second U-shaped deposition groove 16, the free deposition impurities in the water and the impurities blocked by the filter 3 can fall into the first U-shaped deposition groove 15 and the second U-shaped deposition groove 16. When the sewage continues to flow upwards, the free deposition impurities in the water and the impurities blocked by the filter 3 can fall into the U-shaped groove structure 12, so that the purified water flows through the filter 3 into the rear shell 2, and finally flows out from the water outlet 21 of the rear shell 2. Since the impurities in the sewage are carried and collected by the first U-shaped deposition groove 15, the second U-shaped deposition groove 16 and the U-shaped groove structure 12, the impurities can be effectively prevented from flowing back into the water tank or the fish tank from the water inlet 11.

[0057] In an embodiment, as shown in FIG. 1, the top of the front shell 1 is provided with an oil film inlet 17, the inner top of the front shell 1 is provided with a U-shaped groove structure 12, and the U-shaped groove structure 12 is arranged at the bottom of the oil film inlet 17. Figure 5

[0058] It should be noted that the design and function of the oil film inlet 17 are crucial to ensure the filtering effect and prolong the service life of the device. In the filtering system of the water changer, the oil film inlet 17 is used to introduce the oil film in the water, help to remove the oil film on the water surface, increase the light transmittance of the light, and be beneficial to the photosynthesis of the aquatic plants in the water tank. The inner top of the front shell 1 is provided with a U-shaped groove structure 12, and the U-shaped groove structure 12 is arranged at the bottom of the oil film inlet 17, in order to use the U-shaped groove structure 12 to accommodate the oil film and impurities, so as to improve the impurity removal effect and oil film removal effect of the device. Among them, the side closer to each other of the two U-shaped groove structures 12 arranged at the oil film inlet 17 is shorter, and the side farther away from each other is longer (which can wrap one side of the oil film inlet 17), and the short sides of the U-shaped groove structures 12 can form a channel for the sewage flow, which is in communication with the flow channel 4.

[0059] In an embodiment, the front shell 1 and the U-shaped groove structure 12 are of an integrated structure, and the rear shell 2 and the structural rib 22 are of an integrated structure, so as to facilitate the manufacturing and processing of the front shell 1 and the rear shell 2.

[0060] It should be noted that the front shell 1 and the rear shell 2 are used to construct the main support structure of the device, and the front shell 1 and the rear shell 2 can be made of corrosion-resistant metal materials, so as to improve the use strength of the device and avoid corrosion of the front shell 1 and the rear shell 2 during use.

[0061] ​In one embodiment, one of the front shell 1 and the rear shell 2 is provided with a clamping groove, and the other is provided with a clamping piece, and the clamping groove and the clamping piece are clamped and fixed. By setting the clamping groove and the clamping piece, the front shell 1 and the rear shell 2 can be effectively fixed, and the filter element 3 in the containing cavity can be conveniently replaced regularly. Moreover, when one of the front shell 1 and the rear shell 2 appears damage phenomenon, the damaged part can be replaced by disassembling operation, and the undamaged part continues to cooperate, thereby improving the service life of the device and reducing the maintenance cost of the device.

[0062] In addition to the above-mentioned U-shaped grid filter device, the utility model also provides a water changer comprising the U-shaped grid filter device disclosed in the above-mentioned embodiments, and the structures of other parts of the water changer refer to the prior art, which will not be described herein again, but it is necessary to ensure that the water changer can reliably remove impurities in the fluid.

[0063] It should be noted that the first U-shaped deposition tank 15 and the second U-shaped deposition tank 16, the first water inlet 13 and the second water inlet 14 mentioned in the present application are only distinguished by position, and there is no sequence.

[0064] In addition, it should be noted that the "horizontal", "vertical" and the like in the present application indicate the orientation or positional relationship, which is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of simplifying the description and facilitating understanding, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model.
