Description

Technical Field

[0001] This utility model relates to the field of plumbing accessories technology, specifically to a filter, and more particularly to a foldable filter. Background Technology

[0002] There are many types of filters. This utility model relates to filters in the field of daily necessities technology. These are simple filters, typically placed at the drain in a bathroom, used to filter hair and other debris. Existing filters of this type generally use a round cap made of soft rubber material with several small filter holes for water to pass through. Newer filters, such as the ultra-thin round filter cap provided in Chinese Utility Model Patent No. 202221584874.2, incorporate a metal counterweight, solving the problem of previous filter caps being easily washed away by strong water flow. While this ultra-thin design has its advantages, it also has disadvantages. Therefore, there are also filters, such as the one in Chinese Design Patent No. 202130292940.3, whose filter holes are higher in the vertical direction, making them less prone to clogging by hair and other debris.

[0003] While high-quality filters offer advantages such as large drainage capacity and resistance to clogging, in today's context of international trade, products often require long-distance transportation to reach consumers, with warehousing and transportation costs accounting for a significant proportion. Therefore, improvements are necessary. Summary of the Invention

[0004] The purpose of this invention is to design a filter that solves the problem that while current filters with sufficient height have a large drainage capacity and are not easily clogged, they also have high storage and transportation costs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A filter, shaped like a top hat, includes a brim, a body, and a top. The body has several filter holes. The filter is characterized in that the wall thickness at the junction of the upper part of the body and the top is reduced, so that the body can be folded to reduce the overall height of the product.

[0007] In a preferred embodiment, the hat top, brim, and body are integrally formed, and a metal counterweight is provided on the edge of the hat top, which is detachably connected to the hat body.

[0008] In a further preferred embodiment, the counterweight is a ring-shaped counterweight made of zinc alloy, and the inner side of the filter is provided with an installation groove for accommodating the counterweight. During installation, an external force is applied to the counterweight to make it enter the installation groove.

[0009] In a further preferred embodiment, the outer side of the mounting groove is integrally formed with a buckle. During installation, an external force is applied to the buckle to deform it and insert the counterweight. After the external force is removed, the buckle resets and thus holds the counterweight in place.

[0010] In a further preferred embodiment, the outer side of the position where the buckle engages with the hat body is provided with rounded corners.

[0011] In a further preferred embodiment, the included angle between the outer wall of the mounting groove and the inner side of the buckle is 95 degrees to 135 degrees.

[0012] In a further preferred embodiment, the top of the cap at the corresponding location on the inner side of the annular counterweight is intentionally de-rubbed, creating a cavity between the top of the cap and the counterweight.

[0013] In a preferred embodiment, the center of the cap is thickened so that it can be used in conjunction with a pop-up drainer. Pressing the center of the cap can indirectly act on the pop-up cover of the pop-up drainer.

[0014] In a preferred embodiment, the wall thickness between the center of the hat top and the edge of the hat top is relatively thin and corrugated, forming a pressing deformation zone; the upper part of the hat body is a folding deformation zone, and the counterweight is located between the pressing deformation zone and the folding deformation zone.

[0015] In a preferred embodiment, the wall thickness at the junction of the upper part of the cap and the top of the cap is reduced by hollowing out from bottom to top.

[0016] The beneficial effects of this utility model are:

[0017] The filter employing this invention features a thinner wall at the junction of the upper part of the cap and the top, allowing the cap to fold under external force, thus reducing the overall height of the product. This enables the use of smaller packaging boxes, lowering logistics and warehousing costs in long-distance trade. Calculations show that selling each product to the US through Amazon currently saves approximately $0.60, a considerable amount for a small item like a filter.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0026] Figure 8 yes Figure 3 A magnified view of part A in the middle. Detailed Implementation

[0027] The filter provided in this specific embodiment is as follows: Figure 1 and Figure 2 As shown, it is shaped like a top hat and includes: a brim 1, a body 2, and a crown 3. The brim 1, body 2, and crown 3 are provided with several filter holes. Figure 3 As shown, the upper part of the hat body 2 connects to the hat top 3 (e.g.) Figure 8 The wall thickness at the location indicated by the middle arrow B is reduced, thus allowing the hat body 2 to be as [likely referring to a specific structure or feature] when an external force is applied to the top 3 of the hat. Figure 4 The product's overall height is reduced by folding, as shown.

[0028] The filter using the technical solution of this utility model has a thinner wall thickness at the connection between the upper part of the cap body 2 and the cap top 3, so that the cap body 2 can be folded when an external force is applied to the cap top 3, thereby reducing the overall height of the product. Therefore, a smaller packaging box can be used to reduce logistics and warehousing costs in ocean trade.

[0029] In the preferred technical solution, such as Figure 5 and Figure 6 As shown, the hat top 3, hat brim 1, and hat body 2 are integrally formed, as... Figure 3 As shown, a metal counterweight 4 is provided on the edge of the cap top 3, and the counterweight 4 is detachably connected to the cap body 2. The counterweight 4 is made of zinc alloy, which has a high density and is reasonably priced. The use of the counterweight 4 significantly increases the overall weight of the filter, making it less likely to be washed away by strong water flow. Moreover, the greater weight allows the cap brim 1 to make a tighter contact with the ground, thus making the filter work more reliably.

[0030] In a further preferred embodiment, the counterweight 4 is as follows: Figure 7 As shown, the ring-shaped counterweight 4 is made of zinc alloy. An installation groove for accommodating the counterweight 4 is provided inside the filter. During installation, external force is applied to the counterweight 4 to guide it into the installation groove. Because the brim 1, hat body 2, and hat crown 3 are integrally molded from soft rubber material, typically silicone, adjusting the size of the installation groove to be slightly smaller than the ring-shaped counterweight 4 allows the groove to spring back and hold the counterweight 4 in place, facilitating installation and removal. Alternatively, the size of the installation groove can be adjusted to be equal to or slightly larger than the ring-shaped counterweight 4, or other methods such as adhesive can be used to bond the two together.

[0031] In a further preferred embodiment, a buckle 5 is integrally formed on the outer side of the mounting groove. During installation, an external force is applied to the buckle 5 to deform it, allowing the counterweight 4 to be inserted. After the external force is removed, the buckle 5 returns to its original position, thus securing the counterweight 4. The buckle 5 ensures more reliable fixation of the counterweight 4.

[0032] In further preferred technical solutions, such as Figure 8 As shown, the outer side of the position where the buckle 5 engages with the hat body has rounded corners, such as... Figure 8 As shown in C, setting a fillet C to reduce localized material usage facilitates demolding.

[0033] In further preferred technical solutions, such as Figure 8 As shown, the angle between the outer wall 21 of the mounting groove and the inner side 51 of the buckle 5 is 95 degrees to 135 degrees. Practice has shown that setting such an angle is beneficial for the buckle 5 to be demolded from the silicone part; otherwise, the buckle 5 may have difficulty being demolded, or even be damaged.

[0034] In further preferred technical solutions, such as Figure 3 As shown, the top of the cap 3 on the inner side of the ring-shaped counterweight 4 is partially debonded, forming a cavity between the top of the cap 3 and the counterweight 4. This design allows the top of the cap 3 to have enough space to deform when pressed, resulting in a better feel and better functionality.

[0035] In a further preferred embodiment, the middle portion 31 of the cap 3 is thickened, allowing it to be used in conjunction with a pop-up drain assembly. Pressing the middle portion 31 of the cap 3 indirectly acts on the pop-up cover of the pop-up drain assembly. This design allows the filter to be used in conjunction with the pop-up drain assembly for better results.

[0036] In a further preferred embodiment, the wall thickness between the middle part 31 and the edge of the cap top 3 is relatively thin and corrugated, forming a pressing deformation zone; the upper part of the cap body 2 is a folding deformation zone, and the counterweight 4 is located between the pressing deformation zone and the folding deformation zone. This arrangement not only does not affect the pressing and folding functions but also minimizes the impact on the filtration function.

[0037] In the preferred technical solution, such as Figure 8 As shown, the wall thickness at the junction of the upper part of the hat body 2 and the hat top 3 is reduced by hollowing out from bottom to top, as... Figure 8 The direction is indicated by the middle arrow B. Practice has shown that conventional ejection methods can cause springback due to stress tension, while this method effectively releases stress and prevents springback. Furthermore, this ejection method is beneficial for mold making and product demolding during production.

[0038] In the preferred embodiment, the filter holes on the cap body 2 are only located at the lower part of the cap body 2. This is because the holes at the lower part of the cap body 2 are sufficient for drainage. If many holes were also made at the upper part, the time required to remove the holes during production would be longer, increasing product costs. In addition, mold costs would also increase.

[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications or substitutions should be considered within the protection scope of the present invention.
