Description

Technical Field

[0001] The utility model relates to the technical field of aquarium culture, and more specifically, to an aquarium culture filter barrel. Background Art

[0002] To raise fish, one must first condition the water. Controlling the water quality during the aquarium culture process is particularly important. In the prior art, there are mainly two ways to treat the cultured water: one is to change the water regularly, that is, directly discharge the cultured water containing pollutants through the sewage pipe and add purified water for supplementation. This method will cause certain pollution and consume more water resources; the other is to filter and recycle the water, that is, use a filtering device to purify the cultured water and then inject it into the culture pond again for recycling the cultured water. However, with long-term filtration, a lot of dirt will accumulate on the filter material, affecting the water flow, increasing the filtration pressure, and deteriorating the filtration effect. This method requires frequent cleaning of the filter media. For the commonly used filter barrels in households, generally, the machine needs to be stopped and the filter media needs to be removed for cleaning. This method is relatively cumbersome, time-consuming and laborious, with low cleaning efficiency, and requires users to manually disassemble and rinse the relatively dirty filter media, resulting in a poor user experience.

[0003] The patent with the publication number CN215085123U discloses a filtering device with a backwashing function, including: a water pipe assembly, the filter box is rotatably connected to the end of the water inlet pipe and can be fixed at multiple angles. The inner cavity of the filter box is provided with filter media. The two ends of the filter box are respectively communicated with the water inlet hole and the water outlet hole, or respectively communicated with the water inlet hole and the sewage discharge hole. Only by changing the relative angle between the filter box and the water inlet pipe can the online backwashing function be realized, improving the cleaning efficiency. However, this design requires users to rotate the filter box to achieve communication with different water outlets, and the operation intensity is still relatively large, with poor convenience. The patent with the publication number WO2013097741A1 discloses a water pollution separation device. A backwashing pipeline is connected between the water inlet pipe and the water outlet pipe of the filter barrel, and a communication valve is arranged between the water inlet pipe, the water outlet pipe and the backwashing pipeline respectively. By controlling the on-off cooperation of the valve groups on different pipelines, the filter media can be automatically flushed using the backwashing pipeline, avoiding the operation of manually disassembling and cleaning the filter media. However, this design requires additional pipeline and valve group structures to be arranged outside the filter barrel, with a more complex structure and higher product cost, and is not suitable for popularization and application. Summary of the Utility Model

[0004] 1. Technical Problems to be Solved by the Utility Model

[0005] Aiming at the situation that the cleaning of the aquarium filter barrel in the prior art is time-consuming, laborious and inconvenient, the utility model intends to provide an aquarium culture filter barrel, which can realize rapid backwashing of the filter media without disassembling the filter media during use, with a simple operation process and effectively improving the user experience.

[0006] 2. Technical Solutions

[0007] To achieve the above object, the technical solution provided by the present utility model is as follows:

[0008] A water filtration bucket for aquarium cultivation of the present utility model includes a detachable barrel body and a barrel cover. A filtration component is placed inside the barrel body, and a water inlet pipe and a water outlet pipe are provided on the barrel cover for the entry of filtered water and the discharge of purified water after filtration, respectively. Specifically, a water dropping seat is provided at the bottom of the barrel cover. The water dropping seat has an inner cavity capable of holding water. The inner cavity of the water dropping seat is connected to the water inlet pipe. The water dropping seat is provided with an inlet communication port, an outlet communication port, and a sewage communication port. The inlet communication port is used to connect the inner cavity of the barrel body to the inner cavity of the water dropping seat; the outlet communication port is used to connect the inner cavity of the barrel body to the water outlet pipe; the sewage communication port is used to connect the inner cavity of the barrel body to the inner cavity of the water dropping seat. Correspondingly, a control switch is further provided on the barrel cover. The control switch is used to control the on-off of the inlet communication port or the sewage communication port, so that the inner cavity of the water dropping seat is connected to the inner cavity of the barrel body through the inlet communication port, or the inner cavity of the water dropping seat is connected to the inner cavity of the barrel body through the sewage communication port. A pull-out sewage pipe is provided at the bottom of the barrel body. One end of the sewage pipe located inside the barrel body is closed by a sewage plug. When the sewage pipe is pulled outwards, the inner end of the sewage pipe is separated from the sewage plug, so that the sewage pipe is connected to the inner cavity of the barrel body.

[0009] Furthermore, the filtration bucket of this solution further includes a filtration component. The filtration component is placed in the inner cavity of the barrel body and below the water dropping seat. An inlet channel extending downward to the lower part of the inner cavity of the barrel body is provided inside the filtration component. The inlet channel corresponds to the position of the upper inlet communication port, and the inlet channel is staggered from the position of the sewage communication port, that is, the sewage communication port corresponds downward to the upper surface position of the filtration component. When the inlet communication port is in the open state and the sewage communication port is in the closed state, water enters the lower part of the inner cavity of the barrel body through the water inlet pipe, the inlet communication port, and the inlet channel in sequence. When the inlet communication port is in the closed state and the sewage communication port is in the open state, water enters the upper part of the inner cavity of the barrel body through the water inlet pipe and the sewage communication port. More preferably, the inlet channel corresponds to the positions of the upper inlet communication port and the bottom water inlet of the water inlet pipe. When the inlet communication port is in the connected and open state, the three form a straight path, and the filtered water directly enters the lower part of the inner cavity of the barrel body through the water inlet pipe, the inlet communication port, and the inlet channel.

[0010] In the design of traditional water filtration buckets for aquarium cultivation, the bottom water inlet of the water inlet pipe directly corresponds to and is connected to the position of the inlet channel inside the filtration component. The inlet channel generally runs through the upper and lower height directions of the filtration component and is connected downward to the inner cavity of the barrel body. The water source to be filtered directly enters the inlet channel through the water inlet pipe and then reaches the bottom of the barrel body. Then the water level gradually rises from bottom to top, and the filtration component is used for layer-by-layer full filtration. The purified water after filtration is discharged through the water outlet pipe. When it is necessary to clean the dirt on the filtration component, it is necessary to take out the filtration component and manually rinse it, which is relatively inconvenient to operate.

[0011] In this solution, by designing a water inlet seat with multiple connecting ports and cooperating with a control switch, rapid conversion of different water flow directions can be achieved. Specifically, in practice, it is preferred that the upper end of the inlet connecting port corresponds to the bottom water inlet of the water inlet pipe, and the lower end corresponds to the water inlet channel in the filtering component. The connecting state between the water inlet pipe and the water inlet channel can still be achieved by using the inlet connecting port to realize the normal filtering process. When the inlet connecting port is closed, at this time, when the bottom water inlet of the water inlet pipe is connected to the upper surface of the filtering component through the sewage connecting port, the water inlet pipe and the water inlet channel are in a non-connected state. Clean water can be introduced into the water inlet pipe, and the clean water enters the water storage inner cavity of the water inlet seat and then directly enters the inner cavity of the barrel through the sewage connecting port, that is, the clean water flushes layer by layer from the upper surface of the filtering component to the lower surface, and finally the sewage after flushing is discharged through the sewage pipe, realizing internal automatic backwashing. The filtering component does not need to be taken out during the flushing process, and the operation is relatively convenient. Further in practice, it is preferred that the bottom of the barrel cover and the water inlet seat are detachably installed, which is convenient for maintenance in case of abnormalities.

[0012] In this solution, to improve the safety of the sewage discharge process, the sewage pipe is set as a pull-out structure and sealed with a sewage plug to avoid pressure impact on the inside of the sewage pipe by the internal water source during the filtering and backwashing processes, which is beneficial to improving the use safety and avoiding accidental water leakage.

[0013] As a specific implementation option for the control switch, further, the control switch includes a switch part and a blocking part. The switch part is rotationally and movably installed on the barrel cover, and the blocking part is located at the bottom end of the switch part. By rotating the switch part, the blocking part can be rotated to cover the inlet connecting port, so that the inner cavity of the water inlet seat is connected to the inner cavity of the barrel through the sewage connecting port; or the blocking part can be rotated to cover the sewage connecting port, so that the inner cavity of the water inlet seat is connected to the inner cavity of the barrel through the inlet connecting port. In this way, the user can directly rotate the switch part on the barrel cover to control the on-off of the water flow in different directions, and the operation process is relatively convenient. Moreover, the distinguishing marks of the filtering function and the backwashing function can be further marked on the rotation path of the switch part, which is convenient for the user to accurately and intuitively judge the state of the internal water flow direction and distinguish the use under different states.

[0014] To ensure that the blocking part can be accurately shifted to the corresponding position to completely close the corresponding communication port, further, limiting rib plates are respectively provided on the outer sides of the inlet communication port and the sewage discharge communication port on the water inlet seat. The limiting rib plates extend upward to a height higher than the top heights of the inlet communication port and the sewage discharge communication port, that is, also higher than the height of the bottom wall of the blocking part, so as to be able to limit the rotation angle of the blocking part. When the blocking part rotates to be blocked by the limiting rib plate, it reminds the user that the rotary switch part has reached the position, avoiding the displacement of the blocking part exceeding the range and unable to fully cover the corresponding communication port. Further, to improve the stability of the repeated deflection of the blocking part, a supporting part for supporting above the blocking part is provided along the rotation path of the blocking part at the bottom of the bucket lid, avoiding deformation of the blocking part due to water pressure, etc., and also improving the structural stability during its long-term use. Further, a connecting rib plate is connected between the outer wall of the inlet communication port and the outer wall of the sewage discharge communication port. The height of the connecting rib plate is the same as the heights of the outer wall of the inlet communication port and the outer wall of the sewage discharge communication port, which not only helps to improve the structural strength, but also can provide lower support during the repeated deflection of the blocking part.

[0015] As a specific design of the sewage discharge pipe, further, the sewage discharge pipe includes a connecting pipe section located outside the bucket body, and a main pipe section that can extend into the bucket body through a pulling and fitting manner. The inner end of the main pipe section is closed by a sewage discharge plug. A connecting port is provided at the outer end of the connecting pipe section for connecting to an external sewage discharge pipe. A handle for facilitating pulling is provided on the connecting pipe section, which is convenient for the user to directly perform the pulling operation, making it more convenient.

[0016] To further improve the safety of the discharge of flushing sewage, further, the sewage discharge pipe is rotatably installed in cooperation with the bucket body. After the sewage discharge pipe is pulled out to be separated from the sewage discharge plug, it can rotate circumferentially outside the bucket body. In practice, it is preferably that the outer end of the sewage discharge pipe is initially in a vertical distribution state with the water outlet facing upward at the high part to prevent sewage from flowing out easily; after rotation, the outer end of the sewage discharge pipe can be in a horizontal state or with the water outlet facing downward, which is convenient for external connection and sewage outflow. In practice, a sewage discharge valve can be provided at the end of the sewage discharge pipe outside the bucket body. By adopting the method of first pulling, then rotating, and finally opening the valve for sewage discharge, the safety of sewage discharge can be effectively improved, avoiding inconvenience caused by accidental sewage outflow.

[0017] In cooperation with the pull-out design of the sewage discharge pipe, to achieve a compact design of the filter bucket, further, a receiving cavity for receiving the sewage discharge pipe that is recessed inward is provided on the outer wall of the bucket body. When the sewage discharge pipe is closed by the sewage discharge plug, at least part of the sewage discharge pipe is hidden in the receiving cavity. After the sewage discharge pipe is separated from the sewage discharge plug, the sewage discharge pipe extends outside the bucket body. This helps to streamline the volume occupation of the filter bucket in the non-flushing sewage discharge state, and the overall shape is beautiful and compact.

[0018] In order to ensure the stability of pulling out the sewage pipe, a limit part is further provided on the outer wall of the main pipe section of the sewage pipe located inside the barrel body. The limit part is used to limit the axial displacement of the sewage pipe when it is pulled out of the barrel body to prevent the sewage pipe from being over-pulled or not pulled into place.

[0019] As a selective design of the sewage plug, further, the sewage plug includes a closing portion for closing the inner end port of the sewage pipe, and an embedded portion that cooperates to be embedded in the inner cavity of the sewage pipe, and the outer wall of the embedded portion is sealed with the inner wall of the sewage pipe, such as a sealing ring. This not only facilitates the sewage plug to be quickly embedded in the sewage pipe and closed, but also ensures the sealing of the sewage plug and the sewage pipe, and prevents the water source in the barrel from entering the sewage pipe in the non-flushing sewage state.

[0020] To facilitate the installation of the drain plug, a positioning plate for installing the drain plug is further provided in the barrel body, and a fixed slot matching the positioning plate is provided on the side of the drain plug facing away from the drain pipe, so as to facilitate the rapid positioning and installation of the drain plug, ensure its position stability and correspondence with the position of the drain pipe port, and avoid the position of the two being offset after repeated pulling and pulling.

[0049] The present invention will be further described below with reference to the embodiments.

[0050] Embodiment

[0051] Combined with Figures 1 - 17As shown in the figure, an aquarium filtration bucket according to this embodiment includes a detachable barrel body 100 and a barrel cover 200. For example, a plurality of snap-fit components 102 are provided around the barrel body 100 for snap-fit installation with the barrel cover 200. In practice, various detachable installation methods can be adopted, which will not be elaborated here. The filter component 110 is placed inside the barrel body 100, and the barrel cover 200 is provided with a water inlet pipe 201 and a water outlet pipe 202. In this embodiment, a water dropping seat 220 is provided at the bottom of the barrel cover 200. The water dropping seat 220 has an inner cavity capable of holding water. The inner cavity of the water dropping seat 220 is connected to the water inlet pipe 201. The water dropping seat 220 is provided with an inlet communication port 222, an outlet communication port 221, and a sewage communication port 223. The inlet communication port 222 is used to connect the inner cavity of the barrel body 100 with the inner cavity of the water dropping seat 220; the outlet communication port 221 is used to connect the inner cavity of the barrel body 100 with the water outlet pipe 202; the sewage communication port 223 is used to connect the inner cavity of the barrel body 100 with the inner cavity of the water dropping seat 220; a control switch 210 is also provided on the barrel cover 200. The control switch 210 is used to control the on-off of the inlet communication port 222 or the sewage communication port 223, so that the inner cavity of the water dropping seat 220 is connected to the inner cavity of the barrel body 100 through the inlet communication port 222, or the inner cavity of the water dropping seat 220 is connected to the inner cavity of the barrel body 100 through the sewage communication port 223. A pull-out sewage pipe 300 is also provided at the bottom of the barrel body 100. One end of the sewage pipe 300 located inside the barrel body 100 is closed by a sewage plug 320. When the sewage pipe 300 is pulled outwards, the inner end of the sewage pipe 300 is separated from the sewage plug 320, so that the sewage pipe 300 is connected to the inner cavity of the barrel body 100.

[0052] Furthermore, the filtration bucket of this embodiment further includes a filtration component 110. The filtration component 110 is placed in the inner cavity of the barrel body 100 and is located below the water dropping seat 220. An intake channel 111 extending downward to the lower part of the barrel body 100 is provided inside the filtration component 110; the intake channel 111 corresponds to the position of the upper inlet communication port 222. More preferably, the intake channel 111 corresponds to the positions of the upper inlet communication port 222 and the bottom water outlet of the water inlet pipe 201 in sequence. The three form a straight channel. When the inlet communication port is in a connected and open state, the filtered water enters the lower part of the inner cavity of the barrel body 100 through the water inlet pipe 201, the inlet communication port 222, and the intake channel 111 in sequence; the intake channel 111 is staggered from the position of the upper sewage communication port 223, so that when the inlet communication port 222 is closed, the water source basically does not enter the intake channel 111, but enters the filtration component 110 inside the barrel body 100 from top to bottom through the sewage communication port 223.

[0053] Specifically, in combination with Figures 4 - 11As shown, the water inlet seat 220 may include a bottom wall portion 227 covering the upper end of the barrel body 100, and an annular wall portion 228 extending upward circumferentially around the bottom wall portion 227. A water-containing inner cavity with a certain height is formed between the annular wall portion 228 and the bottom wall portion 227. For example, Figure 9 and Figure 10 As shown, the inlet communication port 222, the outlet communication port 221, and the sewage discharge communication port 223 are provided on the bottom wall portion 227 and penetrate through the thickness direction vertically. The outlet communication port 221 may extend upward with an annular barrel wall of a certain height to closely correspond and fit with the bottom water outlet position of the water outlet pipe 202. The bottom of the outlet communication port 221 corresponds to the upper position of the filter assembly 110, facilitating the subsequent filtered purified water to be discharged through the outlet communication port 221 and the water outlet pipe 202 in sequence. The upper end of the inlet communication port 222 may extend with an annular barrel wall of a certain height corresponding to the position of the water inlet pipe 201, and the lower end may extend downward with an annular barrel wall of a certain height to closely correspond to the position of the water inlet channel 111, facilitating the effective concentration of the water flow and enabling it to smoothly concentrate and enter the water inlet channel 111. Similarly, the upper end of the sewage discharge communication port 223 may also extend with an annular barrel wall of a certain height, and the lower end of the sewage discharge communication port 223 corresponds to the upper position of the filter assembly 110. More precisely, preferably, the top heights of the inlet communication port 222 and the sewage discharge communication port 223 on the water inlet seat 220 are maintained on the same plane and are both lower than the top height of the outlet communication port 221. The outlet communication port 221 extends upward to correspond to and be in basic contact and fit with the bottom water outlet position of the water outlet pipe 202, facilitating the formation of a water outlet path, and the water in the inner cavity of the water inlet seat 220 is not easily introduced into the outlet communication port 221. Similarly, preferably, the bottom height of the inlet communication port 222 on the water inlet seat 220 is lower than the bottom height of the sewage discharge communication port 223. The bottom of the inlet communication port 222 extends to correspond to and be in basic contact and fit with the position of the water inlet channel 111 on the filter assembly 110, facilitating the formation of a downward water inlet path.

[0054] In practice, the filter assembly 110 may adopt an integrated filter element or a split filter element, etc. Preferably, a multi-layer filter basket structure may be adopted, that is, multiple layers of filter media are installed and fixed through the filter basket frame 112 to form an integral filter media adapted to the shape of the inner cavity of the barrel body 100. The integral filter media is placed in the barrel body 100, and a water inlet channel 111 is provided inside the integral filter media. The water inlet channel 111 preferably penetrates the height direction of the integral filter media. Combining with Figure 3 the direction indicated by the arrow, so that the water source can directly reach the lower part of the barrel body 100 through the water inlet pipe 201 and the water inlet channel 111, and then gradually filter from bottom to top using multiple layers of filter media. The filtered sewage is discharged through the water outlet pipe 202. The filter assembly 110 may also adopt other forms of filter media, which will not be elaborated here.

[0055] In actual application of this embodiment, it can have a sewage filtration function and an internal backwashing and cleaning function. Under the sewage filtration function, the control switch 210 controls the bottom water inlet of the water inlet pipe 201 to be connected to the water inlet channel 111 through the inlet communication port 222. At this time, the sewage discharge communication port 223 cannot be connected to the inner cavity of the barrel 100. The sewage to be filtered can only enter the water inlet channel 111 through the water inlet pipe 201 and the inlet communication port 222, realizing layer-by-layer filtration from bottom to top, and then finally discharged through the water outlet pipe 202. Under the internal backwashing and cleaning function, the control switch 210 controls the inner cavity of the water drop seat 220 to be connected to the inner cavity of the barrel 100 through the sewage discharge communication port 223, that is, the bottom water inlet of the water inlet pipe 201 is connected to the upper surface of the filtration component 110 through the sewage discharge communication port 223. At this time, the water inlet pipe 201 cannot be connected to the inlet communication port 222. The water source entering the water inlet pipe 201 will enter the water-containing inner cavity of the water drop seat 220, and then flow downward through the sewage discharge communication port 223, so as to directly wash the filtration component 110 from top to bottom, realizing reverse flushing and cleaning of the filter media. After flushing, the sewage is discharged through the sewage pipe 300 at the bottom.

[0056] In this solution, to improve the safety of the sewage discharge process, the sewage pipe 300 is set as a pull-out structure and is closed by a sewage plug 320. Specifically, the sewage outlet 103 is generally arranged at the bottom of the barrel 100. The bottom of the barrel 100 mentioned here can be either on the bottom wall surface of the barrel 100 or on the side wall surface of the barrel 100 near the lower part. In this embodiment, for the convenience of pipe connection and practical application, the sewage outlet 103 can be opened on the side wall surface near the bottom of the barrel 100. The sewage pipe 300 is movably installed in the sewage outlet 103, and a sealing member is provided between the sewage pipe 300 and the sewage outlet 103 to maintain sealing. A sewage valve 302 can be further arranged at the outer end of the sewage pipe 300 to control the on-off of the pipeline. In the normal filtration state, the inside of the sewage pipe 300 is closed by the sewage plug 320, so that the sewage in the barrel will not enter the sewage pipe 300, and the water flow pressure impact on the sewage pipe 300 is also avoided. Especially when the sewage valve 302 is accidentally opened and forgotten to be closed, the direct outflow of sewage through the sewage pipe 300 is avoided to cause damage. Only when in the backwashing and cleaning state, at this time the user actively pulls out the sewage pipe 300 to separate the sewage pipe 300 from the sewage plug 320, and the backwashing water can enter the sewage pipe 300 and be discharged. Even if the sewage valve 302 is accidentally opened and forgotten to be closed, if the user does not actively pull out the sewage pipe 300, the water flow will not overflow, effectively improving the use safety and avoiding other losses caused by water overflow.

[0057] As a specific implementation option for the control switch 210, in combination with Figure 6As shown, the control switch 210 includes a switch part 211 and a blocking part 212. The switch part 211 is rotatably mounted on the bucket lid 200, and the blocking part 212 is located at the bottom end of the switch part 211. Specifically, the bucket lid 200 is provided with a pipe inlet 204 for fitting and installing the water inlet pipe 201, a pipe outlet 205 for fitting and installing the water outlet pipe 202, and a switch mounting opening 203 for rotatably mounting the switch part 211. The switch part 211 passes through the switch mounting opening 203, and the bottom of the switch part 211 has a blocking part 212. The blocking part 212 extends horizontally. Rotating the switch part 211 can drive the blocking part 212 to rotate synchronously. The inlet communication port 222 and the sewage communication port 223 are arranged close to each other and are located on the rotation path of the blocking part 212, and the bottom surface of the blocking part 212 can basically contact and cover the upper end of the inlet communication port 222 or the sewage communication port 223 to achieve a closed isolation effect. When the blocking part 212 rotates to the upper end of the inlet communication port 222 and covers the inlet communication port 222, the inlet communication port 222 is isolated from the water inlet pipe 201. At this time, the water entering the water inlet pipe 201 can only flow downward through the sewage communication port 223. When the blocking part 212 rotates to the upper end of the sewage communication port 223 and covers the sewage communication port 223, the sewage communication port 223 is isolated from the water inlet pipe 201. At this time, the water entering the water inlet pipe 201 can only enter the water inlet channel 111 downward through the inlet communication port 222. The control switch 210 is designed with a simple structure, low production cost, and very convenient for users to operate, with a good experience. Users can directly rotate the switch part 211 on the bucket lid 200 to control the on-off of the water path in different directions. The operation process is relatively convenient, and the distinguishing marks or arrow directions of the filtering function and the backwashing function can be further marked on the rotation path of the switch part 211, which is convenient for users to accurately and intuitively judge the internal water path direction state and distinguish the use in different states.

[0058] In practice, further, it is preferably to adopt a detachable installation between the bottom of the bucket lid 200 and the water inlet seat 220. For example, a plurality of installation parts 224 are provided on the bottom wall part 227 of the water inlet seat 220, and they are fixedly installed with the bucket lid 200 by bolt fastening, etc. This is also convenient for timely opening for internal maintenance in case of abnormalities, especially for checking and maintaining the state of the control switch 210.

[0059] Such as Figure 6As shown, the outer walls of the inlet communication port 222 and the sewage discharge communication port 223 can be connected by a connecting rib plate 225. The height of the connecting rib plate 225 is flush with the top heights of the inlet communication port 222 and the sewage discharge communication port 223, which not only enhances the structural strength but also can support the bottom of the blocking part 212 during the rotation of the blocking part 212. Similarly, a support part 206 is provided along the rotation path of the blocking part 212 at the bottom of the bucket lid 200 for supporting above the blocking part 212 during rotation, preventing the blocking part 212 from deforming under water pressure during long-term use, etc., and also improving its structural stability during long-term use and ensuring the accuracy of its position shielding and isolation. Optionally, the sewage discharge communication port 223 can adopt a kidney-shaped hole structure, and the opening area is larger than the area of the inlet communication port 222, facilitating the rapid downward flow of water during flushing. The blocking part 212 correspondingly adopts a kidney-shaped flat plate structure with a suitable shape, which is simple and lightweight and can completely cover the sewage discharge communication port 223.

[0060] To ensure that the blocking part 212 can accurately shift to the corresponding position to completely close the corresponding communication port, further, on the water inlet seat 220, limiting rib plates 226 are respectively provided on the outer sides of the inlet communication port 222 and the sewage discharge communication port 223 in the opposite direction. The upward extension height of the limiting rib plates 226 is higher than the top heights of the inlet communication port 222 and the sewage discharge communication port 223, that is, also higher than the bottom wall height of the blocking part 212, so as to be able to limit the rotation angle of the blocking part 212. For example, in combination with Figure 9 in terms of orientation, when the blocking part 212 rotates to completely cover the inlet communication port 222, at this time, the right side of the blocking part 212 abuts against the position of the right limiting rib plate 226, restricting further rotation to the right; when the blocking part 212 rotates to completely cover the sewage discharge communication port 223, at this time, the left side of the blocking part 212 abuts against the position of the left limiting rib plate 226, restricting further rotation to the left. When blocked by the limiting rib plate 226, it reminds the user that the rotary switch part 211 has reached the position, preventing the displacement of the blocking part 212 from exceeding the range and unable to fully cover the corresponding communication port.

[0061] As an implementable design for the sewage pipe 300, in combination with Figure 12 and Figure 13 shown, the sewage pipe 300 includes a connecting pipe section 311 located outside the barrel body 100 and a main pipe section 310 that can extend into the barrel body 100 through a pulling and fitting manner. The inner end port of the main pipe section 310 is closed by a sewage plug 320, and a connecting port is provided at the outer end of the connecting pipe section 311 for connecting to an external sewage pipe. The sewage valve 302 is also installed at the outer end of the connecting pipe section 311. A handle 301 for facilitating pulling is provided on the connecting pipe section 311. Through the handle 301, it is convenient for the user to directly perform the pulling operation, which is more convenient. Specifically, the handle 301 can be provided at the bottom of the connecting pipe section 311.

[0062] In order to further improve the safety of flushing sewage discharge, the sewage pipe 300 is further installed in a rotational cooperation with the barrel body 100. After the sewage pipe 300 is pulled out and separated from the sewage plug 320, it can be rotated around the circumference outside the barrel body 100. In practice, it is preferred that the outer end of the sewage pipe 300 is initially in a vertical distribution state, with the water outlet upward at a high position to prevent sewage from flowing out easily; and after rotation, the outer end of the sewage pipe 300 can be horizontal or the water outlet is downward, which is convenient for external connection and sewage outflow, such as Figure 17 As shown, state a is the vertical distribution state of the sewage pipe 300, and state b is the horizontal distribution state of the sewage pipe 300. Compared with the direct pulling and draining method, the multiple protection methods of first pulling, then rotating, and finally opening the valve to drain sewage further increase the protection performance and ensure that the user actively selects the drainage function, which can effectively improve the safety of sewage discharge and avoid the inconvenience caused by accidental sewage outflow.

[0063] In order to realize the compact design of the filter barrel, in conjunction with the pull-out design of the sewage pipe 300, further, the outer wall of the barrel body 100 is provided with a receiving chamber 101 which is recessed inward and used to accommodate the sewage pipe 300. When the sewage pipe 300 is closed by the sewage plug 320, the sewage pipe 300 is at least partially hidden in the receiving chamber 101. Preferably, the sewage pipe 300 and the sewage valve 302 arranged on the upper part are completely hidden in the receiving chamber 101. After the sewage pipe 300 is separated from the sewage plug 320, the sewage pipe 300 extends to the outside of the barrel body 100. In this way, the sewage pipe 300 can always be hidden in the chamber in the normal filtering state, and only needs to be pulled out and displayed in the backwashing state, which effectively simplifies the volume occupied by the filter barrel, and the overall shape is beautiful and compact. In coordination with this, the bottom of the filter assembly 110 is provided with a corresponding avoidance chamber 113 corresponding to the position of the receiving chamber 101.

[0064] In order to ensure the pulling stability of the sewage pipe 300, further, a limiting portion 313 is provided on the outer wall of the main pipeline section 310 of the sewage pipe 300 located inside the barrel body 100, and the limiting portion 313 is used to limit the axial displacement of the sewage pipe 300 when it is pulled out of the barrel body 100, so as to prevent the sewage pipe 300 from being over-pulled or not pulled in place. The limiting portion 313 can be distributed around the outer wall of the main pipeline section 310. Specifically, a movable matching connecting portion 312 is surrounded at the outer end of the main pipeline section 310, and the connecting portion 312 is used to cooperate with the sewage outlet 103 at the bottom of the barrel body 100, so that the sewage pipe 300 is installed on the barrel body 100, and the connecting portion 312 can adopt a connecting flange structure. In practice, the main pipeline section 310 can choose to adopt a two-section splicing structure, and the limiting portion 313 is set on the rear section of the pipeline close to the direction of the sewage plug 320, so as to facilitate processing and installation.

[0065] As an alternative design for the sewage drain plug 320, further, the sewage drain plug 320 includes a closing portion 321 for closing the inner end port of the sewage pipe 300, and an embedded portion that fits and embeds into the inner cavity of the sewage pipe 300. The embedded portion can be set as a cylindrical shape that extends a certain length in the middle of the closing portion 321, and a conical guiding section can be provided at the front end of the cylinder close to the sewage pipe 300 direction to facilitate the quick insertion of the embedded portion into the sewage pipe 300. A sealing ring 323 is provided between the outer wall of the embedded portion and the inner wall of the sewage pipe 300. Specifically, a sealing groove can be opened on the outer wall of the embedded portion, and the sealing ring 323 is located in the sealing groove. In this way, it is not only convenient for the sewage drain plug 320 to be quickly embedded into the sewage pipe 300 and achieve closure, but also can ensure the sealing performance between the sewage drain plug 320 and the sewage pipe 300, and prevent the water source in the barrel from entering the sewage pipe 300 in the non-flushing sewage state.

[0066] To facilitate the installation of the sewage drain plug 320, further, a positioning plate 106 for installing the sewage drain plug 320 is provided inside the barrel 100. A fixed clamping groove 324 that cooperates with the positioning plate 106 is provided on the side of the sewage drain plug 320 facing away from the sewage pipe 300, which is convenient for quickly positioning and installing the sewage drain plug 320, ensuring its position stability, and the correspondence with the port position of the sewage pipe 300, and preventing the positions of the two from shifting after multiple pulls. Specifically, an annular fixing portion 322 is further provided outside the closing portion 321 of the sewage drain plug 320, and the fixed clamping groove 324 is formed between the fixing portion 322 and the closing portion 321. Correspondingly, combined with Figure 15 As shown, two groups of fixing plates 105 are provided in parallel at the bottom of the barrel 100. The positioning plate 106 is connected between the two groups of fixing plates 105, and a positioning groove 107 extending downward is provided at the top of the positioning plate 106. The fixed clamping groove 324 of the sewage drain plug 320 correspondingly fits and embeds into the positioning groove 107, and the fixing portion 322 and the closing portion 321 of the sewage drain plug 320 are respectively located on both sides of the positioning groove 107, realizing the positioning installation of the sewage drain plug 320 in the barrel 100 and ensuring the position accuracy of the sewage drain plug 320. The fixing plate 105 can also be used as the bottom support component of the upper filter assembly 110 above to support the upper filter assembly 110. Similarly, to maintain the placement stability of the filter assembly 110, multiple groups of support ribs 104 can be provided circumferentially around the bottom of the barrel 100.

[0067] In this solution, by designing a water inlet seat 220 with multiple communication ports and cooperating with a control switch 210, rapid conversion of different water flow directions can be achieved, including the upward filtering water flow direction and the downward backwashing water flow direction. An anti-backwashing self-cleaning function is added on the basis of the conventional filtering function. During the flushing process, the filtering component 110 does not need to be taken out, and the operation is relatively convenient, effectively improving the user experience. At the same time, with the design of the pull-out sewage pipe 300, it helps to further ensure the drainage safety and avoid accidental water leakage. For the aquarium breeding environment, the filtering bucket of this solution can not only meet the simple and rapid conversion of the filtering function and the backwashing function, but also effectively improve the safety of sewage discharge and effectively avoid sewage leakage. For household aquarium breeding, the user experience is greatly improved.

This description is not restrictive, but only one of the implementation manners of the present invention, and the actual situation is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments to this technical solution without creative efforts without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
