Description

Technical Field

[0001] The utility model relates to the technical field of aquarium cultivation, and more specifically, to a water inlet seat, a bucket cover assembly for an aquarium cultivation filter bucket, and an aquarium cultivation filter bucket. Background Art

[0002] To raise fish, it is necessary to first condition the water. Controlling the water quality during the aquarium cultivation process is particularly important. In the prior art, there are mainly two ways to treat the cultivation water: one is to change the water regularly, that is, directly discharge the cultivation 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 cultivation water and then inject it into the cultivation pool again for recycling the cultivation 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 material. For the commonly used filter buckets in households, generally, the machine needs to be stopped and the filter material 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 material, 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 material. 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 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 bucket, and a communication valve is respectively arranged between the water inlet pipe, the water outlet pipe and the backwashing pipeline. By controlling the on-off cooperation of the valve groups on different pipelines, the filter material can be automatically flushed using the backwashing pipeline, avoiding the operation of manually disassembling and cleaning the filter material. However, this design requires an additional pipeline and valve group structure outside the filter bucket, 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 filter material in the filter bucket in the prior art is time-consuming, laborious and inconvenient, the utility model intends to provide a water inlet seat, a bucket cover assembly for an aquarium cultivation filter bucket, and an aquarium cultivation filter bucket. The aquarium cultivation filter bucket of this solution does not need to disassemble the filter material, can realize rapid flushing and cleaning of the filter material, has a simple operation process, and can effectively improve the user experience.

[0006] 2. Technical solution

[0007] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is:

[0008] The utility model discloses an aquaculture filter barrel, comprising a detachably mounted barrel body and a barrel cover, wherein the barrel body is used for placing a filter assembly, and the barrel cover is provided with a water inlet pipe and a water outlet pipe, which are respectively used for filtered water to enter and purified water to be discharged after filtration; the special feature of the present scheme is that a water drop seat is provided at the bottom of the barrel cover, the water drop seat has an inner cavity capable of containing water, the inner cavity of the water drop seat is connected with the water inlet pipe, and the water drop seat is provided with an inlet connecting port, an outlet connecting port and a sewage connecting port, wherein the inlet connecting port is used for connecting the inner cavity of the barrel body with the inner cavity of the water drop seat; the outlet connecting port is used for connecting the inner cavity of the barrel body with the water outlet pipe; the sewage connecting port is used for connecting the inner cavity of the barrel body with the inner cavity of the water drop seat; correspondingly, a control switch is also provided on the barrel cover, and the control switch is used for controlling the opening and closing of the inlet connecting port or the sewage connecting port, so that the inner cavity of the water drop seat is connected with the inner cavity of the barrel body through the inlet connecting port, or the inner cavity of the water drop seat is connected with the inner cavity of the barrel body through the sewage connecting port; a sewage connecting port is provided at the bottom of the barrel body, so as to discharge sewage after flushing.

[0009] Furthermore, the filter barrel of the present solution also includes a filter assembly, which is placed in the inner cavity of the barrel body and located below the drain seat, and a water inlet channel extending downward to the lower part of the barrel body is provided in the filter assembly; the water inlet channel corresponds to the position of the inlet connection port located above, and the water inlet channel is staggered with the position of the sewage connection port, that is, the sewage connection port corresponds downward to the upper surface position of the filter assembly; so that when the inlet connection port is in an open state and the sewage connection port is in a closed state, water enters the lower part of the inner cavity of the barrel body through the water inlet pipe, the inlet connection port and the water inlet channel in sequence; when the inlet connection port is in a closed state and the sewage connection port is in an open state, water enters the upper part of the inner cavity of the barrel body through the water inlet pipe and the sewage connection port. More preferably, the water inlet channel corresponds to the position of the inlet connection port located above and the bottom water inlet of the water inlet pipe, and when the inlet connection port is in a 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 connection port and the water inlet channel.

[0010] In the design of traditional filter barrels for aquaculture, the bottom water inlet of the water inlet pipe directly corresponds to the position of the water inlet channel in the filter component and maintains communication. The water inlet channel generally runs through the upper and lower height directions of the filter component and is downwardly connected to the inner cavity of the barrel body. The water source to be filtered directly enters the water inlet channel through the water inlet pipe and reaches the bottom of the barrel body. Then the water level gradually rises from bottom to top, and the filter component is used to perform sufficient filtration layer by layer. The clean water is discharged through the outlet pipe. When it is necessary to clean the dirt on the filter component, the filter component needs to be taken out and rinsed manually, which is inconvenient.

[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 outlet 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 through the inlet connecting port, realizing the normal filtering process. When the inlet connecting port is closed, when the bottom water outlet 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 at this time. 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 barrel inner cavity through the sewage connecting port, that is, the clean water flushes layer by layer from top to bottom on the upper surface of the filtering component, 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. In practice, further, 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] 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 cooperatively 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. Further, a distinguishing mark for the filtering function and the backwashing function can be marked on the rotation path of the switch part, which is convenient for the user to accurately and intuitively judge the water flow direction state inside and distinguish the use in different states.

[0013] In practice, a further optimized design that can be selected is that the top wall surfaces of the inlet connecting port and the sewage connecting port on the water inlet seat are on the same plane and are both lower than the top height of the outlet connecting port, and the heights are kept flush. The outlet connecting port extends upward to correspond to the bottom water outlet of the water outlet pipe and is basically in contact and cooperation, which is convenient for forming a water outlet path, and the water in the inner cavity of the water inlet seat is not easily introduced into the outlet connecting port. Similarly, preferably, the bottom height of the inlet connecting port on the water inlet seat is lower than the bottom height of the sewage connecting port, and the bottom of the inlet connecting port extends to correspond to the water inlet channel on the filtering component and is basically in contact and cooperation, which is convenient for forming a water inlet path. In practice, it can be selected that the top planes of the inlet connecting port and the sewage connecting port on the water inlet seat are on the same horizontal plane or on the same inclined plane, and the blocking part can be rotated to cover different positions in the rotation path by rotating the switch part.

[0014] To ensure that the blocking part can accurately shift to the corresponding position to completely close the corresponding communication port, further, limiting rib plates are respectively provided on the outside 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 height 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 being 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, and the height of the connecting rib plate is the same as the height 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. Further, a sewage valve is also provided on the sewage pipe.

[0015] The present utility model also provides a bucket lid assembly for an aquarium culture filtration bucket, which includes a bucket lid and a water inlet seat. The specific designs of the bucket lid and the water inlet seat are the same as those of the bucket lid and the water inlet seat in the above-mentioned aquarium culture filtration bucket, and will not be elaborated.

[0016] The present utility model also provides a water inlet seat for an aquarium culture filtration bucket, which is configured to be installed at the bottom of the bucket lid of the filtration bucket. The specific design of the water inlet seat is the same as that of the water inlet seat in the above-mentioned aquarium culture filtration bucket, and will not be elaborated. Optionally, the water inlet seat includes a bottom wall part and a ring wall part that surrounds the bottom wall part circumferentially and extends upward. A water-containing inner cavity with a certain height is formed between the ring wall part and the bottom wall part; the inlet communication port, the outlet communication port and the sewage discharge communication port are all opened on the bottom wall part; for the convenience of realizing the detachable connection between the water inlet seat and the bucket lid, it is preferably provided with an installation part for connection on the water inlet seat.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0045] The present invention will be further described below with reference to the embodiments.

[0046] Embodiment

[0047] Combined with Figures 1 - 17As shown in the figure, a water aquaculture filter barrel according to this embodiment includes a detachably installed barrel body 100 and a barrel cover 200. For example, a plurality of buckle members 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 a water inlet pipe 201 and a water outlet pipe 202 are provided on the barrel cover 200. 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 communicated with the water inlet pipe 201, and an inlet communication port 222, an outlet communication port 221, and a sewage discharge communication port 223 are provided on the water dropping seat 220. The inlet communication port 222 is used to communicate 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 communicate the inner cavity of the barrel body 100 with the water outlet pipe 202; the sewage discharge communication port 223 is used to communicate the inner cavity of the barrel body 100 with the inner cavity of the water dropping seat 220; a control switch 210 is further 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 discharge communication port 223, so that the inner cavity of the water dropping seat 220 is communicated with 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 communicated with the inner cavity of the barrel body 100 through the sewage discharge communication port 223. A sewage discharge pipe 300 is further provided at the bottom of the barrel body 100 for discharging flushing sewage. Further, a sewage discharge valve 302 can be provided on the sewage discharge pipe 300.

[0048] Further, the filter barrel of this embodiment further includes a filter component 110. The filter component 110 is placed in the inner cavity of the barrel body 100 and is located below the water dropping seat 220, and a water inlet channel 111 extending downward to the lower part of the barrel body 100 is opened in the filter component 110; the water inlet channel 111 corresponds to the position of the upper inlet communication port 222. More preferably, the water inlet 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 the 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 water inlet channel 111 in sequence; the water inlet channel 111 is staggered from the position of the upper sewage discharge communication port 223, so that when the inlet communication port is closed, the water source basically does not enter the water inlet channel 111, but enters the upper part of the inner cavity of the barrel body 100 from top to bottom through the sewage discharge communication port 223, that is, enters the internal filter component 110.

[0049] Specifically, in combination with Figures 4 - 11 As shown in the figure, the water dropping 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 holding 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 10As 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 can extend upward by a certain height of an annular barrel wall to closely correspond and fit with the bottom water inlet 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 purified water after filtration 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 can extend by a certain height of an annular barrel wall corresponding to the position of the water inlet pipe 202, and the lower end can extend downward by a certain height of an annular barrel wall to closely correspond to the position of the water inlet passage 111, facilitating the effective concentration of the water flow and enabling it to smoothly concentrate and enter the water inlet passage 111. Similarly, the upper end of the sewage discharge communication port 223 can also extend by a certain height of an annular barrel wall, and the lower end of the sewage discharge communication port 223 corresponds to the upper position of the filter assembly 110. More precisely, preferably, in this embodiment, the top heights of the inlet communication port 222 and the sewage discharge communication port 223 on the water inlet seat 220 are kept flush, and both are lower than the top height of the outlet communication port 221. The outlet communication port 221 extends upward to correspond to and is basically in contact and fit with the bottom water inlet position of the water outlet pipe 202, facilitating the formation of a water outlet passage, 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 is basically in contact and fit with the position of the water inlet passage 111 on the filter assembly 110, facilitating the formation of a downward water inlet passage.

[0050] In practice, the filter assembly 110 can adopt an integrated filter element or a split filter element, etc. Preferably, a multi-layer filter basket structure can be adopted, that is, multiple layers of filter media are installed and fixed through the filter basket frame 112 into an overall filter media adapted to the shape of the inner cavity of the barrel body 100. The overall filter media is placed in the barrel body 100, and a water inlet passage 111 is provided inside the overall filter media. The water inlet passage 111 preferably penetrates through the height direction of the overall filter media. Combining Figure 3 with 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 passage 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 can also adopt other forms of filter media, which will not be elaborated here.

[0051] 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 communicated with the water inlet channel 111 through the inlet communication port 222. At this time, the sewage discharge communication port 223 cannot be communicated with the water inlet pipe 201. 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 bottom water inlet of the water inlet pipe 201 to be directly communicated with the upper surface of the filtration component 110 through the sewage discharge communication port 223. At this time, that is, the water inlet pipe 201 cannot be communicated with the inlet communication port 222. The water source entering the water inlet pipe 201 will enter the inner cavity chamber of the water dropping 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 the reverse flushing and cleaning of the filter media. After flushing, the sewage is discharged through the sewage pipe 300 at the bottom.

[0052] As a specific implementation option for the control switch 210, in combination with Figure 6As shown in the figure, the control switch 210 includes a switch part 211 and a blocking part 212. The switch part 211 is rotatably installed on the bucket cover 200, and the blocking part 212 is located at the bottom end of the switch part 211. Specifically, a pipe inlet 204 is provided on the bucket cover 200 for fitting and installing the water inlet pipe 201, a pipe outlet 205 is provided for fitting and installing the water outlet pipe 202, and a switch installation opening 203 is provided for rotatably installing the switch part 211. The switch part 211 passes through the switch installation opening 203, and a blocking part 212 is provided at the bottom of the switch part 211. 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 is very convenient for users to operate, with a good experience. Users can directly rotate the switch part 211 on the bucket cover 200 to control the on-off of the water path in different directions. The operation process is relatively convenient, and the distinction 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, so as to facilitate users to accurately and intuitively judge the internal water path direction state and distinguish the use in different states.

[0053] In practice, further, it is preferably to adopt a detachable installation between the bottom of the bucket cover 200 and the water inlet seat 220. For example, multiple groups 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 cover 200 by bolts. 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.

[0054] Such as Figure 6As shown, the outer walls of the inlet connection port 222 and the sewage connection port 223 can be connected by a connecting rib plate 225. The connecting rib plate 225 is located on the rotation path of the blocking portion 212, which not only enhances the structural strength, but also supports the bottom of the blocking portion 212 during the rotation of the blocking portion 212. Similarly, the bottom of the barrel cover 200 is provided with a support portion 206 along the rotation path of the blocking portion 212, which is used to support the top of the blocking portion 212 during the rotation process. The upper and lower parts cooperate to prevent the blocking portion 212 from being deformed by water pressure during long-term use, and also improve its long-term structural stability and ensure the accuracy of its position shielding and isolation. Optionally, the sewage connection port 223 can adopt a waist-shaped hole structure, the opening area of ​​which is larger than the area of ​​the inlet connection port 222, so that the water can flow down quickly during flushing. The blocking portion 212 correspondingly adopts a waist-shaped flat plate structure with a corresponding shape, which is simple and light in structure and can completely cover the sewage connection port 223.

[0055] In order to ensure that the blocking portion 212 can accurately shift to the corresponding position to completely close the corresponding communication port, further, the water drop seat 220 is provided with a limiting rib plate 226 on the outer side of the inlet communication port 222 and the sewage communication port 223 in the opposite direction. The limiting rib plate 226 extends upward to a height higher than the height of the blocking portion 212, thereby limiting the rotation angle of the blocking portion 212. Figure 9 In terms of orientation, when the blocking portion 212 rotates to completely cover the inlet connection port 222, the right side of the blocking portion 212 abuts against the right side limit rib 226, limiting further rotation to the right; when the blocking portion 212 rotates to completely cover the sewage connection port 223, the left side of the blocking portion 212 abuts against the left side limit rib 226, limiting further rotation to the left. When blocked by the limit rib 226, the user is reminded that the rotation switch portion 211 is in place, preventing the blocking portion 212 from moving beyond the limit rib 226 and failing to fully cover the corresponding connection port.

[0056] In this solution, to improve the safety of the sewage discharge process, the bottom of the barrel body 100 is installed in a drawable fit with the sewage discharge pipe 300. One end of the sewage discharge pipe 300 located inside the barrel body 100 is closed by a sewage discharge plug 320. When the sewage discharge pipe 300 is pulled outwards, the inner end of the sewage discharge pipe 300 is separated from the sewage discharge plug 320, so that the sewage discharge pipe 300 is communicated with the inner cavity of the barrel body 100. The sewage discharge pipe 300 is set as a drawable structure and is closed by the sewage discharge plug 320. Specifically, a sewage discharge port 103 is provided at the bottom of the barrel body 100, and the sewage discharge pipe 300 is movably installed in the sewage discharge port 103, and a sealing member is provided between the sewage discharge pipe 300 and the sewage discharge port 103 to maintain sealing. A sewage discharge valve 302 can be provided at the outer end of the sewage discharge pipe 300 to control the on-off of the pipeline. In the normal filtration state, the inside of the sewage discharge pipe 300 is closed by the sewage discharge plug 320, so that the sewage in the barrel will not enter the sewage discharge pipe 300, and the water flow pressure impact on the sewage discharge pipe 300 is also avoided. Especially when the sewage discharge valve 302 is accidentally opened and forgotten to be closed, the direct outflow of sewage through the sewage discharge 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 discharge pipe 300 to separate the sewage discharge pipe 300 from the sewage discharge plug 320, and the backwashing water can enter the sewage discharge pipe 300 and be discharged. Even if the sewage discharge valve 302 is accidentally opened and forgotten to be closed, if the user does not actively pull out the sewage discharge pipe 300, the water flow will not overflow, effectively improving the use safety and avoiding other losses caused by water overflow.

[0057] As an implementable design of the sewage discharge pipe 300, in combination with Figure 12 and Figure 13 shown, the sewage discharge 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 drawable fit. The inner end port of the main pipe section 310 is closed by the sewage discharge plug 320, and a connecting port is provided at the outer end of the connecting pipe section 311 for connecting to an external sewage discharge pipe. The sewage discharge valve 302 is also installed at the outer end of the connecting pipe section 311. A handle 301 for easy drawing is provided on the connecting pipe section 311. Through the handle 301, it is convenient for the user to directly perform the drawing operation, which is more convenient. Specifically, the handle 301 can be provided at the bottom of the connecting pipe section 311.

[0058] To further improve the safety of the discharge of the flushing sewage, furthermore, the sewage discharge pipe 300 is installed in a rotational fit with the barrel body 100. After the sewage discharge pipe 300 is pulled out to be separated from the sewage discharge plug 320, it can rotate circumferentially outside the barrel body 100. In practice, it is preferably that the outer end of the sewage discharge pipe 300 is initially in a vertical distribution state, with the water outlet facing upwards at the high part to avoid the easy outflow of sewage; after rotation, the outer end of the sewage discharge pipe 300 can be in a horizontal state or the water outlet facing downwards, which is convenient for external connection and sewage outflow, as Figure 17As 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.

[0059] 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.

[0060] 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.

[0061] 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 near the sewage pipe 300 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 convenient for the sewage drain plug 320 to be quickly embedded into the sewage pipe 300 and achieve closure, and it can ensure the sealing performance between the sewage drain plug 320 and the sewage pipe 300, preventing the water source in the barrel from entering the sewage pipe 300 during the non-flushing sewage state.

[0062] 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 card slot 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 on the outside of the closing portion 321 of the sewage drain plug 320, and the fixed card slot 324 is formed between the fixing portion 322 and the closing portion 321. Correspondingly, as shown in 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 card slot 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.

[0063] In this solution, by designing a water inlet seat 220 with multiple connecting 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-impact 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 household aquarium farming, 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 without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
