Description

Technical Field

[0001] This utility model specifically relates to an extractor and a replacement filter structure using the extractor. Background Technology

[0002] In daily life, floor drains are a key component of drainage systems, and they are usually equipped with floor drain filters to filter debris from the water and prevent pipe blockage. However, existing floor drain filters have many inconveniences in use.

[0003] Because floor drains are usually installed low, and there is a specific fit between the filter and the drain body, removing the filter when cleaning or replacing it becomes a major challenge. Traditional floor drain filters often have a simple structure and lack a dedicated extraction mechanism. Users can only reach directly into the drain to grab it, which not only easily gets their hands dirty, but also makes it difficult to apply enough force to remove some tightly installed filters, and may even damage the filter due to improper force. Utility Model Content

[0004] In view of the defects of the prior art, the technical problem to be solved by this utility model is to provide an extractor and a replacement filter structure for using the extractor.

[0005] An extractor includes a handle with a lifting portion at its lower end. The lifting portion has a first protrusion extending downward, and a first limiting flange extending around the first protrusion. A through hole is provided on the lifting portion around the first protrusion. A push rod is movably disposed inside the handle, and the end of the push rod can pass through the through hole and move below the lifting portion.

[0006] In one embodiment, an elastic element is provided between the push rod and the grip rod, which causes the push rod to initially maintain a displacement away from the lifting part.

[0007] In one embodiment, the grip bar is provided with a drive member that can drive the top rod to move toward the lifting part.

[0008] In one embodiment, the driving component includes a driving button, the grip has an inner cavity, the push rod is movably disposed in the inner cavity and can reciprocate along the axial direction of the grip, one side of the grip has an opening communicating with the inner cavity, the driving button is movably disposed in the opening, one side of the push rod has a slot, one end of the driving button is located in the slot and extends with an inclined pressure block, one end of the slot has a first guide slope that can abut against the inclined surface of the inclined pressure block.

[0009] In one embodiment, a second limiting flange is provided on the periphery of the drive button, and the second limiting flange movably abuts against the inner side of the inner cavity.

[0010] In one embodiment, the lower side of the first limiting flange is a second guide slope.

[0011] In one embodiment, the lifting portion is provided with limiting walls on both sides symmetrically, and a third guide slope is provided on the opposite inner side of the two limiting walls, with the first protrusion located between the two limiting walls.

[0012] In one embodiment, an extension rod is detachably connected to the upper end of the grip.

[0013] A filter replacement structure includes the extractor described above, and also includes a drain screen. The drain screen includes a drain portion and a second protrusion that can be elastically deformed. The second protrusion has a cavity with a downward opening. A connecting hole communicating with the cavity is provided at the upper end of the second protrusion. The first protrusion can be inserted into the connecting hole. The first limiting flange can pass through the connecting hole with the first protrusion and abut against the top side of the cavity.

[0014] In one embodiment, the second protrusion is a thin-walled conical protrusion or a trapezoidal protrusion.

[0015] In summary, the advantages of this utility model over the prior art are:

[0016] The extractor of this application inserts into the target component (such as the perforation of a floor drain filter) through the first protrusion, and then achieves a stable connection with the target component through the first limiting flange, ensuring that the target component will not easily fall off during the extraction process; and through the push rod, it can pass through the perforation and move to below the lifting part. After extraction, the target component can be pushed out of the extraction part by the push rod, realizing convenient separation of the target component from the extractor. The operation is simple and efficient. Attached image description;

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1 to 4 The present invention preferably provides an extractor, characterized in that it includes a handle 1, a lifting portion 2 at the lower end of the handle 1, a first protrusion 4 extending downward within the lifting portion 2, a first limiting flange 5 extending around the first protrusion 4, and a through hole 6 penetrating around the first protrusion 4 on the lifting portion 2. A push rod 7 is movably disposed within the handle 1, the end of the push rod 7 passing through the through hole 6 and displaced below the lifting portion 2. Specifically, the lifting portion is fixed to the lower end of the handle, passes through the first protrusion into the target component (such as the perforation of a drain filter), and is stably connected to the target component by the first limiting flange, ensuring that the target component will not easily fall off during extraction; and the push rod can pass through the through hole and displaced below the lifting portion. After extraction, the target component can be pushed out of the extraction portion by the push rod, achieving convenient separation of the target component from the extractor, making the operation simple and efficient.

[0024] Furthermore, an elastic element 8 is provided between the top rod 7 and the grip rod 1, which causes the top rod 7 to initially maintain a displacement away from the lifting part 2. Specifically, the elastic element can be a tension spring or a spring, preferably a tension spring, with its two ends connected between the grip rod and the top rod. This elastic element prevents the top rod from arbitrarily passing through the perforation in the initial state, avoiding interference with the extraction operation when the top rod is not in operation. Especially when grasping a drain filter, the stability of the grasping operation is not affected by accidental movement of the top rod. Only when it is necessary to separate the target component is the top rod moved by external force overcoming the elastic force of the elastic element, ensuring the stability of the extractor's operation.

[0025] Furthermore, the grip 1 is provided with a driving member 9 that can drive the push rod 7 to move towards the lifting part 2. Further, the driving member 9 includes a driving button 91. The grip 1 has an inner cavity 92, the push rod 7 is movably disposed within the inner cavity 92 and can reciprocate along the axial direction of the grip 1. One side of the grip 1 has an opening 93 communicating with the inner cavity 92. The driving button 91 is movably disposed within the opening 93. One side of the push rod 7 has a slot 94. One end of the driving button 91 extends into the slot 94 with an inclined pressure block 95. One end of the slot 94 has a first guide slope 96 that abuts against the inclined surface of the inclined pressure block 95.

[0026] The drive component provides convenient driving force for the movement of the push rod. After removing the drain filter, the operator only needs to operate the drive component to easily control the push rod to move towards the extraction part, pushing the filter out. This eliminates the need for manual pushing of the push rod, improving operational convenience and accuracy. Specifically, the lateral displacement of the drive button is converted into the axial displacement of the push rod through the cooperation of the drive button, the inclined pressure block, and the first guide slope. The transmission method is simple and reliable. After removing the drain filter, the operator only needs to press the drive button to move the push rod, easily separating the filter from the extractor. This convenient and labor-saving operation improves the ease of use of the extractor.

[0027] Furthermore, a second limiting flange 97 is provided around the drive button 91, and the second limiting flange 97 movably abuts against the inner side of the inner cavity 92. Specifically, the second limiting flange can limit the range of movement of the drive button within the opening, prevent the drive button from falling off the grip, and ensure the stability and reliability of the drive component's operation.

[0028] Furthermore, the lower side of the first limiting flange 5 is a second guide slope 11. Specifically, the second guide slope plays a guiding role in the process of the first protrusion engaging with the connection hole of the drain filter, making it easier for the first protrusion to be inserted into the connection hole, reducing the difficulty of the connection operation, improving the connection efficiency, and making the preparation work for removing the drain filter smoother.

[0029] Furthermore, the lifting part 2 is symmetrically provided with limiting walls 12 on both sides, and a third guide slope 13 is provided on the opposite inner side of the two limiting walls 12, with the first protrusion 4 located between the two limiting walls 12. Specifically, the limiting walls can limit the drain filter, preventing the filter from shifting laterally during extraction and ensuring the stability of extraction. The third guide slope acts as a guide when the filter and the extraction part are engaged, facilitating the quick and accurate engagement of the filter with the first protrusion and improving the convenience of extracting the drain filter.

[0030] Furthermore, an extension rod 14 is detachably connected to the upper end of the handle 1. Specifically, the upper end of the handle is detachably connected to the extension rod via a threaded connection, snap-fit ​​connection, or interference fit. The extension rod allows for flexible adjustment of the overall length of the extractor according to the depth of the drain, enabling the extractor to adapt to drains of different depths. This expands the extractor's applicability and improves its versatility, allowing for convenient extraction of drain filters in both shallow and deep water areas.

[0031] A filter replacement structure includes the aforementioned extractor and a drain screen. The drain screen includes a drain portion 15 and a second protrusion 16 capable of elastic deformation. The second protrusion 16 has a cavity 17 with a downward opening. A connecting hole 18 communicating with the cavity 17 is provided at the upper end of the second protrusion 16. A first protrusion 4 can be inserted into the connecting hole 18, and a first limiting flange 5 can pass through the connecting hole 18 with the first protrusion 4 and abut against the top side of the cavity 17. Specifically, by utilizing the first protrusion and the first limiting flange of the extractor in conjunction with the connecting hole and cavity of the second protrusion of the drain screen, a stable gripping of the drain screen can be achieved, facilitating its removal from the installation position. The elastic deformation characteristic of the second protrusion facilitates the insertion and removal of the first protrusion, making the replacement of the drain screen more convenient and solving the problem of difficult extraction using traditional methods.

[0032] Furthermore, the second protrusion 16 is a thin-walled conical or trapezoidal protrusion. Specifically, the thin-walled conical or trapezoidal protrusion structure has better elastic deformation capability, which is more conducive to the first protrusion passing through the connecting hole and the first limiting flange abutting and separating from the top side of the cavity. This further improves the flexibility and reliability of the drain screen and extractor, making the filter replacement operation smoother and reducing the difficulty of operation.
