Description

Technical Field

[0001] This utility model relates to the field of aquarium equipment technology, and in particular to a sewage discharge structure for a fish tank filter and a fish tank filter. Background Technology

[0002] Currently available smart aquarium filters generally adopt a one-piece sealed housing design in pursuit of higher filtration performance and integration. However, this sealed structure has significant technical shortcomings in terms of maintenance and cleaning, especially in effectively removing deposits from the bottom of the filter chamber.

[0003] Traditional cleaning methods typically rely on inserting a drain hose through the top opening of the filter to pump out the water. This method has fundamental shortcomings: First, the drainage efficiency is low and incomplete, as top pumping mainly removes the liquid from the middle and upper layers, and is extremely ineffective at removing stubborn impurities (such as fish feces and uneaten food) that have settled to the bottom due to gravity; second, due to structural limitations, a certain amount of sewage and suspended debris will always remain at the bottom of the chamber and cannot be completely emptied.

[0004] These unremoved bottom deposits can have serious consequences: First, the anaerobic decomposition of the deposits at the bottom continuously releases toxic substances such as ammonia and nitrite, leading to water quality deterioration and directly harming the health of fish. Second, the accumulation of sludge can clog the bottom flow channels, water pump inlets, or filter media gaps, resulting in reduced water flow and decreased performance of the filter, as well as increasing the risk of water pump impeller wear and jamming, thus shortening the service life of the equipment.

[0005] Therefore, there is an urgent need in the field for a solution that can easily remove deposits from the bottom of filters. Utility Model Content

[0006] The purpose of this application is to overcome the shortcomings of the prior art and provide a sewage discharge structure and aquarium filter for aquarium filters, which can directly discharge sediment from the bottom of the filter, is easy to operate, and can effectively extend the life of the equipment.

[0017] In one possible embodiment, the sealing plug is made of an elastic material, at least a portion of which has a larger external dimension than the inner diameter of the drain outlet, so as to achieve a seal through an interference fit.

[0018] In one possible embodiment, the sealing plug includes one or more waterproof ribs, the outer diameter of which is larger than the inner diameter of the drain outlet.

[0019] In one possible embodiment, an assembly groove is formed on the housing, and the connecting arm is detachably disposed in the assembly groove, wherein the assembly groove is arc-shaped.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0037] Unless the context requires otherwise, throughout the specification and claims, the word “comprising” and its variations, such as “including” and “having”, shall be understood to have an open, inclusive meaning, that is, to be interpreted as “including, but not limited to”.

[0038] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings to provide a clearer understanding of the purpose, features, and advantages of this utility model. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of this utility model, but are merely illustrative of the essential spirit of the technical solution of this utility model.

[0039] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0040] The singular forms “a” and “the” used in this specification and the appended claims include plural references unless otherwise expressly stated herein. It should be noted that the term “or” is generally used to mean “and / or” unless otherwise expressly stated herein.

[0041] In the following description, in order to clearly demonstrate the structure and working method of this utility model, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0042] like Figures 1 to 3 As shown, the wastewater discharge structure for the aquarium filter 100 in this embodiment includes a sealing plug 1, a housing 2, and a connecting arm. A wastewater discharge port 201 is opened at the bottom of the filter housing 2. Specifically, a removable sealing plug 1 is provided below the side wall 204 of the housing 2. The sealing plug 1 seals against the wastewater discharge port 201 to close it. After the sealing plug 1 is removed, the wastewater discharge port 201 is opened for wastewater discharge. Figure 1 As shown, the drain outlet 201 is preferably located at the lowest position of the bottom of the housing 2. The principle behind this design is that all solid particles and suspended matter that settle due to gravity will eventually gather here. When the sealing plug 1 is opened, these contaminants can be discharged directly and smoothly under the action of gravity, thereby achieving a cleaning effect.

[0043] The seal between the sealing plug 1 and the drain port 201 is crucial to ensuring that the filter does not leak during normal operation. For example... Figure 4As shown, the sealing plug 1 is provided with at least one annular waterproof rib 101. The outer diameter of the waterproof rib 101 is designed to be slightly larger than the inner diameter of the drain port 201. When the sealing plug 1 is pressed into the drain port 201, the waterproof rib 101 undergoes elastic deformation, forming a tight interference fit with the inner wall of the drain port 201. This interference fit sealing method based on elastic materials provides a simple, effective, and reliable static sealing solution. Multiple waterproof ribs 101 can form multiple sealing barriers, further enhancing waterproof security.

[0044] Besides sealing, reliable fixation of the sealing plug 1 is also crucial. This application provides multiple fixation mechanisms. First, a waterproof fixing buckle 102 is provided on the sealing plug 1. For example... Figure 3 As shown, the shape of the waterproof fixing buckle 102 is complementary to the internal structure of the drain outlet 201. When the sealing plug 1 is installed in place, the waterproof fixing buckle 102 will fasten onto the inner wall of the housing 2. This "fastening" action creates a mechanical interlock, which can effectively prevent the sealing plug 1 from accidentally falling off due to water flow impact or vibration during daily use.

[0045] Secondly, such as Figures 1 to 3 As shown, this application embodiment introduces a connecting arm structure. In one embodiment, the connecting arm is specifically an elastic arm 3 integrally formed with the sealing plug 1. The other end of the elastic arm 3 is connected to an operating handle 4. The entire assembly of the sealing plug 1, elastic arm 3, and operating handle 4 is connected to the disassembly port 203 on the filter housing 2 via the operating handle 4. Figure 2 and Figure 3 As shown, the operating handle 4 can be detachably inserted into the disassembly port 203. The mating structure between the disassembly port 203 and the operating handle 4 can be, for example, a groove and a slider, a snap-fit ​​and a slot, etc., which allows the user to complete the installation and fixation with a simple pushing or pressing action. For example, a locking block 2031 is provided in the disassembly port 203, and the operating handle 4 has a slot 41, and the locking block 2031 can be inserted into the slot 41.

[0046] The detachable connection between the operating handle 4 and the disassembly port 203 greatly improves the convenience of maintenance. When cleaning is required, the user only needs to apply a pulling force to the operating handle 4 to remove the entire sealing plug assembly from the housing 2; after cleaning, the operating handle 4 can be snapped back into the disassembly port 203.

[0047] Of course, in another embodiment, the operating handle 4 can also be fixedly installed in the disassembly port 203, so that the connecting arm and the sealing plug 1 can be connected to the housing, thus preventing the sealing plug 1 from being lost.

[0048] Alternatively, preferably, the connecting arm can be a flexible arm 3.

[0049] There are many ways to fix the connecting arm. For example, a special mounting groove 202 can be made on the housing 2, and then the connecting arm (elastic arm 3) can be directly pressed into and fastened in the mounting groove 202. The size of the mounting groove 202 can be slightly smaller than the size of the corresponding part of the elastic arm 3, and the elastic deformation of the elastic arm 3 itself can be used to form an interference fit for fixation. This method also achieves detachability, but the fixing point may be different from the position of the operating handle 4.

[0050] The elastic arm 3 serves more than just a connection. Due to its inherent elasticity, the elastic arm 3 can bend and extend during the user's removal and installation of the sealing plug 1, providing the necessary operating space and tolerance, making operation more effortless, and reducing the risk of damage to components due to excessive force. This explains in principle why using an elastic arm can improve user experience and component lifespan. Furthermore, the user can pull on the elastic arm 3 to remove the sealing plug 1.

[0051] Preferably, the assembly groove 202 has an arc-shaped structure, which allows the elastic arm 3 to be long enough.

[0052] In a preferred embodiment, the sealing plug 1, the elastic arm 3, and the operating handle 4 are integrally molded from a corrosion-resistant elastic material (e.g., silicone).

[0053] Now, the working process of the entire sewage discharge structure is described with reference to the attached diagram. When the filter is working normally, the sealing plug 1 reliably seals at the sewage discharge port 201. The waterproof rib 101 and the waterproof retaining buckle 102 work together to ensure no leakage. When sewage discharge is required, the user simply pinches the operating handle 4 and applies force in the direction away from the housing 2. Since the operating handle 4 is detachably connected to the disassembly port 203, it can be easily removed with a little force. The user then pulls the sealing plug 1 out of the sewage discharge port 201 using the operating handle 4 and the elastic arm 3. At this time, all the dirt and sewage accumulated at the lowest point of the housing will be quickly and thoroughly discharged from the sewage discharge port 201 under gravity. After sewage discharge, the user repositions the sealing plug 1 back into the sewage discharge port 201 until the waterproof retaining buckle 102 engages with a "click," and the operating handle 4 also re-engages into the disassembly port 203, thus completing the entire cleaning process. This process requires no tools, is simple, and usually takes less than 3 minutes to complete.

[0054] If the operating handle 4 is fixedly connected to the disassembly port 203, then by pulling out the elastic arm 3 and holding the elastic arm 3, the sealing plug 1 can be pulled out.

[0055] Finally, this application also protects an aquarium filter 100 that includes any of the above-described drainage structures. Because this aquarium filter 100 possesses the drainage structures described in this application, it inherits all the aforementioned beneficial effects, including a longer service life, more stable filtration performance, and a more convenient maintenance experience.

[0056] In summary, the embodiments of this application creatively solve the long-standing problem of bottom dirt removal by using a core structure—a drain outlet located at the lowest point of the filter housing and a removable sealing plug. Through specific designs and expansion of various alternative solutions for sealing methods (such as interference fits and waterproof ribs), fixing structures (such as waterproof fasteners, assembly grooves, and disassembly ports), and connection methods (such as flexible arms, detachable connections, and fixed connections), a well-structured and comprehensive technical solution system is formed, ultimately achieving the combined technical effects of thorough wastewater discharge, efficient maintenance, water quality assurance, and extended equipment lifespan. The preferred embodiments of this utility model have been described in detail above; however, it should be understood that, if necessary, aspects of the embodiments can be modified to utilize various aspects, features, and concepts from patents, applications, and publications to provide other embodiments.

[0057] In light of the detailed description above, these and other changes can be made to the embodiments. Generally, the terminology used in the claims should not be considered limited to the specific embodiments disclosed in the specification and claims, but should be understood to include all possible embodiments together with the full scope of equivalents enjoyed by these claims.

[0058] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
