Description

Technical Field

[0001] The present disclosure relates to the technical field of water purification equipment, and specifically to a quick-removal purification filter and a water purification container.

Background Art

[0002] Municipal tap water is prone to secondary pollution during the transportation process and contains harmful substances such as impurities, heavy metals, and microorganisms. Conventional water purification filters often adopt reverse osmosis or nanofiltration technology, require the addition of a pressure pump, have high costs, and complex structures. In addition, bacteria are likely to breed in the filter, so the microorganisms exceed the standards. Although there is already a gravity purification filter, there are problems such as the pressure relief being clogged, the water flow resistance being large, and the detachment being inconvenient. For example, the conventional exhaust hole is a single hole, resulting in a limited pressure relief effect, the filter screen crossbeam structure is simple, resulting in an increased water flow resistance, and for the connection between the filter and the cup body, screws are frequently used, making the detachment cumbersome. Therefore, there is a strong demand for an improved purification filter to improve the pressure relief efficiency, reduce the resistance, and achieve quick removal.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The technical problem to be solved by the present disclosure is to provide a quick-removal purification filter and a water purification container in order to solve the problems in the prior art such as poor pressure relief effect, large water flow resistance, and inconvenient detachment.

Means for Solving the Problems

[0004] To solve the above problems, the present disclosure provides the following technical solutions.

[0005] A quick-removal purification filter includes an open housing, a sterilization box provided near the bottom of the housing, the sterilization box includes a filter mesh and a filter lid, two pressure relief holes provided in the center of the filter lid, a water flow regulating hole provided at the bottom of the housing, male and female resin filtration areas provided below the filter mesh in the housing, an activated carbon filtration area between the filter mesh and the filter lid, a removable lid ring and a support crossbeam provided above the filter lid, the support crossbeam has a double C-shaped structure with opposing sides, a space left in the center of the support crossbeam for passage, an elliptical oblique projection provided on the outer circumference of the lid ring, the projection engaging with a groove in the water purification container, enabling quick attachment and detachment by a rotational locking mechanism.

[0006] By integrating multiple types of filtration media (male and female resins, activated carbon) and a sterilization module, and by providing double pressure relief holes, a unique double C-shaped support beam, and a rotating locking lid ring, the three core problems mentioned in the background technology—poor pressure relief, high water flow resistance, and inconvenient filter attachment and detachment—are comprehensively solved, resulting in a water purification function that is highly efficient, low-resistance, and easy to maintain.

[0007] Optionally, the pressure relief holes are arranged symmetrically, and the hole diameter ranges from 2 mm to 3 mm.

[0008] Compared to a single pressure relief hole, two symmetrically positioned pressure relief holes allow for more rapid and even release of pressure inside the filter, preventing clogging of the pressure relief due to unidirectional pressure differences. Limiting the hole diameter to 2mm-3mm ensures sufficient pressure relief flow rate and speed, while avoiding the impact of excessively large hole diameters on the integrity of the filter mesh structure or the short-circuiting of unfiltered water flow.

[0009] Optionally, the support crossbeam consists of two symmetrical C-shaped brackets and is arranged along the radial direction of the filter cover.

[0010] The function of this structure is to optimize the stability supporting the filter mesh, while its unique shape maximizes the central flow path and significantly reduces the shielding area for water flow, thereby effectively reducing resistance as water passes through the filter mesh.

[0011] A cover is optionally provided on the support crossbeam.

[0012] Its function is to cover the top of the supporting crossbeams and increase the structural strength of the cover.

[0013] The projections are optionally provided in multiple locations and are uniformly distributed, and the grooves are provided corresponding to the projections.

[0014] As a result, after the filter is attached to the cup body, the load received becomes more uniform and stable, avoiding locking failures, reduced sealing performance, or damage to connecting components caused by insufficient or uneven load-bearing points, thereby improving the reliability and durability of the quick-release structure.

[0015] Optionally, a rounded structure is provided on the edge of the projection.

[0016] This reduces friction and mechanical interference during the engagement and disengagement processes of the protrusions and grooves, making rotational operations more labor-saving and smoother, while also reducing wear on the protrusion edges and extending the service life of the quick-release structure.

[0017] Optionally, the housing has a truncated conical shape, and the male and female resin filtration regions have a progressively decreasing capacity from top to bottom.

[0018] The housing is designed in a truncated conical shape, and accordingly, the volume distribution of the male and female resin filtration areas is provided. Its function is to guide the water flow to converge towards the center through the tapered structure, and at the same time, by filling more resin at the top and less at the bottom, the water flow pressure distribution matches the distribution of higher pressure at the top and lower pressure at the bottom, not only making full use of the upper layer resin replacement capacity but also optimizing the spatial layout and reducing the filter volume.

[0019] Optionally, the support crossbeam includes a strip-shaped portion, a first curved portion, a second curved portion, a third curved portion, and a fourth curved portion, wherein the first and second curved portions are provided at the first end of the strip-shaped portion, and the third and fourth curved portions are provided at the second end opposite the first end, the first curved portion, the strip-shaped portion, and the third curved portion form one C-shape, and the second curved portion, the strip-shaped portion, and the fourth curved portion form another C-shape.

[0020] Optionally, the strip-shaped portion is provided with reinforcing ribs protruding in the direction of two pressure relief holes, and the reinforcing ribs and pressure relief holes are provided on opposite sides of the strip-shaped portion.

[0021] Optionally, the central portion of the filter cover is provided to protrude outwards from the filter, and accordingly, the four curved sections are provided with engagement steps at the locations corresponding to the central portion of the filter cover, thereby allowing them to avoid the filter cover.

[0022] Optionally, there may be a gap between the strip-shaped portion and the filter cover.

[0023] Optionally, the outer wall of the filter mesh is provided with a pattern that extends axially to increase friction, and further, multiple openings extending circumferentially are provided on the outer wall of the filter mesh. The pattern and openings are arranged alternately.

[0024] Optionally, the ring includes an outer ring and an inner ring, and the protrusion is provided on the outer wall of the outer ring. The outer ring and the inner ring are connected via a top portion, and a plurality of apertures are provided in the top portion. Corresponding to the positions of the apertures, a plurality of locking portions are provided on the inner wall of the outer ring, and a flange corresponding to the locking portions is provided on the outer periphery of the housing, and the flange is provided in the circumferential direction. The inner ring, the flange, the outer ring, and the top portion form a space communicating with the outside through the apertures.

[0025] Optionally, the inner ring is provided deeper than the outer ring.

[0026] Optionally, the top portion is provided as a flat surface.

[0027] Optionally, the inner ring includes two parts, a cylindrical portion and a tapered portion for contracting inward. The curved portion is connected to the cylindrical portion and the tapered portion simultaneously. The height of the outer ring is provided such that the end of the outer ring is located at the boundary line between the cylindrical portion and the tapered portion.

[0028] A water purification container including a cup body and a purification filter, wherein the purification filter is the quick-removable purification filter, and a concave groove engaging with the protrusion is provided on the inner wall of the cup body, and quick attachment and detachment of the purification filter are realized by rotational locking.

[0029] Optionally, in any cross-section along the radial direction of the cup body, any two concave grooves do not overlap. That is, any two concave grooves are independent of each other. For example, when there are four concave grooves and all four concave grooves are provided identically, the central angle corresponding to each concave groove is less than 90 degrees, and in this way, attachment and detachment can be completed by rotating through a small angle.

[0030] By giving the entire water purification container product advantages such as quick removal of the filter, low resistance, and high-efficiency pressure relief, the water purification container has remarkable advantages of being easy to operate, having high water purification efficiency, and being easy to maintain. <00001�0>[Effects of the Invention]

[0031] By adopting the proposed technology described herein, the following beneficial effects can be obtained compared to the prior art.

[0032] This disclosure effectively solves the clogging problem of conventional single-hole pressure reliefs by providing symmetrical double pressure relief holes, significantly improving water flow efficiency. The adoption of a double C-shaped support beam structure with opposing beams ensures support strength while greatly reducing water flow resistance. A unique rotational locking connection structure (where projections engage with grooves) enables quick and labor-saving attachment and detachment of the filter, greatly improving the user experience. Furthermore, the truncated conical housing and gradient volume filtration area design optimize space utilization and filtration effect, effectively preventing microbial growth when combined with a sterilization box. The overall structure simultaneously achieves multiple beneficial effects—high-efficiency pressure relief, low fluid resistance, convenient maintenance, and reliable purification—under gravity filtration conditions that do not require external power.

[0034] To further understand the contents of this disclosure, the disclosure will be described in detail with reference to the drawings and examples.

[0035] (Examples) Referring to Figures 1-6, the quick-removal purification filter includes an open housing 1, a sterilization box 2 located near the bottom of the housing 1, the sterilization box 2 includes a filter mesh 3 and a filter lid 4, the filter lid 4 has two pressure relief holes 41 in the center, a water flow regulating hole 11 is provided at the bottom of the housing 1, male and female resin filtration areas 92 are provided below the filter mesh 3 inside the housing 1, the space between the filter mesh 3 and the filter lid 4 is an activated carbon filtration area 91, a removable lid ring 5 and a support crossbeam 6 are provided above the filter lid 4, the support crossbeam 6 has a double C-shaped structure with opposing beams, a space 66 for passage remaining in the center between the support crossbeam 6 and the inner wall of the lid ring, and as shown in Figure 6, an elliptical oblique projection 51 is provided on the outer circumference of the lid ring 5. Referring to Figures 5, 6, 7 and 8, the projection 51 engages with a groove 8 inside the water purification container, enabling quick attachment and detachment by a rotational locking mechanism. "Angled placement" refers to a configuration where the projection and the edge of the lid ring are not parallel but have an angle between them. This ensures better sealing performance and avoids misalignment issues when the user is screwing the lid in.

[0036] The lid ring 5 and the support crossbeam 6 may be integrally molded, and the support crossbeam 6 may be detachably connected to the lid ring 5.

[0037] Referring to Figure 2, raw water enters through the filter opening and flows sequentially through each filtration layer. The main operating principle includes: 1) Pressure relief. As the water flow descends and passes through the filter lid 4, the two symmetrical pressure relief holes 41 allow air to be quickly expelled, balancing the internal and external pressures and avoiding air resistance. 2) Filtration. The water flow sequentially passes through the activated carbon filtration area (adsorbs impurities and odors) and the male and female resin filtration areas (removes heavy metals and softens water quality), and finally flows out through the bottom water flow regulating hole. The sterilization box 2 continuously suppresses the growth of microorganisms. 3) Support and quick removal. The backward-facing double C-shaped support crossbeams 6 provide sufficient support, and the empty space within them minimizes water flow resistance. The projection 51 on the lid ring 5 and the groove 8 on the inner wall of the cup body can engage or disengage in less than one rotation, allowing for quick attachment and detachment.

[0038] Referring to Figure 4, the pressure relief holes 41 are arranged symmetrically, with a hole diameter range of 2 mm to 3 mm, and in this embodiment, the hole diameter range may be 2 mm, 2.5 mm, or 3 mm. As the water flow enters the filter and permeates downward, the trapped air collects below the filter cover 4. Because the two pressure relief holes 41 are arranged symmetrically, the air is discharged uniformly and quickly upward from the filter through multiple paths, avoiding the "airlock" phenomenon that can be formed by a single-hole pressure relief, thereby ensuring smooth water flow. The specific hole diameter range is the result of hydrodynamic optimization to achieve the optimal pressure relief effect.

[0039] Referring to Figure 3, the support crossbeam 6 consists of two symmetrical C-shaped brackets and is arranged along the radial direction of the filter cover 4. The two C-shaped brackets are placed back to back, and the "space" formed in their center provides a main passage for the water flow. This structure has a smaller skeletal shielding area compared to conventional cross-shaped or radial crossbeams. The water flow passes through the gap between the central space and the C-shaped brackets with little obstruction, flows smoothly downward, and can effectively reduce water pressure loss.

[0040] Optionally, the support crossbeam 6 includes a strip-shaped portion 61 and four curved portions: a first curved portion 62, a second curved portion 63, a third curved portion 64, and a fourth curved portion 65. The first and second curved portions are provided at the first end of the strip-shaped portion, and the third and fourth curved portions are provided at the second end opposite the first end. The first curved portion, the strip-shaped portion, and the third curved portion form one C-shape, and the second curved portion, the strip-shaped portion, and the fourth curved portion form another C-shape. The two C-shapes share one strip-shaped portion, and the strip-shaped portion is easy to grip by hand. With these two C-shaped shapes, the stability is increased, and the occurrence of cracks can be reduced.

[0041] The position of the strip-shaped portion can correspond to the symmetrical central axis of the two pressure relief holes (line A or B in Figure 4). Each strip-shaped portion is formed with reinforcing ribs 611 protruding in the direction of the two pressure relief holes; that is, the axial cross-section of the strip-shaped portion is similar to a T shape, with reinforcing ribs and pressure relief holes provided on opposite sides of the strip-shaped portion. The height of the strip-shaped portion may be set so that the reinforcing ribs can just support the cover 7.

[0042] The central portion of the filter cover 4 protrudes outward from the filter, and correspondingly, the four curved portions are provided with engagement steps 621 at the points corresponding to the central portion of the filter cover 4. There may be a gap between the strip-shaped portion 61 and the filter cover.

[0043] The outer wall of the filter screen 3 is provided with a pattern 32 that extends axially to increase friction, and the outer wall of the filter screen 3 is further provided with a plurality of openings 31 that extend circumferentially. The pattern 32 and openings 31 are arranged alternately. Optionally, the lid ring includes an outer ring 54 and an inner ring 55, with projections provided on the outer wall of the outer ring 54. The inner ring is provided deeper than the outer ring. The outer ring and the inner ring are connected via a top portion 56, which is provided as a flat surface. A plurality of openings 53 are provided on the top portion. Corresponding to the positions of the openings, a plurality of locking portions 57 are provided on the inner wall of the outer ring, and a flange 12 corresponding to the locking portions is provided on the outer circumference of the housing 1, which is provided circumferentially. The inner ring, flange, outer ring, and top portion form a space that communicates with the outside via the openings 53.

[0044] The inner ring 55 includes two parts: a cylindrical portion 551 and a tapered portion 552 for contraction inward. The curved portion is connected to both the cylindrical portion 551 and the tapered portion 552 simultaneously. The height of the outer ring is precisely at the boundary line between the cylindrical portion and the tapered portion.

[0045] A cover 7 is provided on the support crossbeam 6. To prevent the cover 7 from falling into the recess, a downward-facing ring edge is provided around the circumference of the cover 7, and it also contacts the slope of the cover ring 5 to restrict its position. When using the filter, the cover 7 can be removed first.

[0046] Multiple protrusions 51 are provided and uniformly distributed, and grooves 8 are provided corresponding to the protrusions 51. The multiple protrusions 51 are uniformly distributed along the outer circumference of the lid ring 5 and match with the corresponding number of grooves 8 inside the cup body. When the filter is rotated, multiple points engage simultaneously, so that the connection strength is distributed all around rather than concentrated at a few points, ensuring connection stability and uniform sealing, as well as making attachment and detachment smoother.

[0047] The edges of the projection 51 are provided with a rounded structure. The rounded structure replaces a sharp right-angle edge. When attaching or detaching the filter, the projection 51 slides along the slope of the groove 8, and the rounded design makes the contact surface smoother, effectively reducing the coefficient of sliding friction and achieving a labor-saving effect similar to an "inclined road," allowing the user to complete locking or unlocking with minimal torque.

[0048] Housing 1 has a truncated conical shape, and the male and female resin filtration areas have progressively decreasing volumes from top to bottom. Housing 1 is larger at the top and smaller at the bottom, and the water flow naturally converges towards the center as it flows downwards. The progressive decrease in the volume of the male and female resin filtration areas from top to bottom means that more ion exchange resin is packed into the upper layer, allowing for preferential treatment of most impurity ions in the water. As the water flow moves downwards, the impurity concentration decreases, and the amount of resin required decreases accordingly. This distribution efficiently utilizes the resin exchange capacity, avoids waste of resin at the bottom, and results in a more compact overall structure.

[0049] The water purification container includes a cup body and a purification filter 10. The cup body includes a filter holder 20, and the purification filter is the quick-removal purification filter. The inner wall of the filter holder of the cup body is provided with a groove 8 that engages with a projection 51, and a rotating locking mechanism enables quick attachment and detachment of the purification filter. The inner wall of the cup body of the water purification container has a groove 8 pre-formed to match the projection 51 of the filter lid ring 5. The user places the filter in the cup body and rotates it slightly at an angle (usually less than 90 degrees), causing the projection 51 to slide into the bottom of the groove 8, achieving a locked seal. If replacement or cleaning is necessary, the filter can be removed by rotating it in the reverse direction. The entire system uses gravity to drive the water flow through the filter to complete the purification, requiring no additional power and providing convenient daily drinking water purification.

[0050] The above provides a schematic description of the Disclosure and its embodiments, but this description is not limiting, and the drawings show only one example of an embodiment of the Disclosure, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the Disclosure and designs a similar structural configuration and embodiment without requiring creative effort, without departing from the creative intent of the Disclosure, such design shall also fall within the scope of the Disclosure.
