Description

Technical Field

[0001] This utility model relates to a filter, specifically a water purification filter with upper and lower mesh. Background Technology

[0002] To improve the cleanliness of the water in a cup, activated carbon is usually placed inside. Activated carbon uses its adsorption properties to adsorb impurities in the water, thereby achieving thorough purification.

[0003] Existing technology, such as the Chinese utility model patent with publication number CN213605673U entitled "A Thermos Cup with Purification Function," discloses the following technical solution: "A thermos cup with purification function includes a lid and a body. The body includes a filter plug, an ultraviolet lamp, and an inner liner. The filter plug is inserted into the cup opening, and the ultraviolet lamp is located in the inner liner. Furthermore, a battery is installed in the gap between the cup body and the inner liner, and the ultraviolet lamp is electrically connected to the battery. The connection between the ultraviolet lamp and the battery is waterproofed. The filter plug at the cup opening filters the water poured into the cup, removing large molecular impurities. The ultraviolet lamp in the inner liner kills bacteria in the water, further purifying the water in the thermos cup. A tea strainer is detachably connected below the filter plug. The filter plug consists of a first filter membrane, a second filter membrane, and coconut shell activated carbon. The multi-layered filter membrane effectively filters the water in the thermos cup, while the coconut shell activated carbon not only has an adsorption effect but also gives the water a sweet taste."

[0004] While the above method can purify the water in the cup to some extent, the activated carbon is located at the top of the tea strainer, between the lid and the strainer. Therefore, it can only adsorb and purify the water during the pouring process. However, during pouring, the water flows quickly from top to bottom, and the activated carbon's adsorption rate is limited, resulting in some water remaining unpurified. Utility Model Content

[0005] The purpose of this utility model is:

[0006] The structure of the water filter in the cup has been improved by setting up a double-layer filter, with activated carbon filled in the lower layer. This ensures that the activated carbon is kept away from the cup lid, allowing the water to pass through the activated carbon for adsorption and purification during pouring. When the water in the cup reaches a certain volume, the activated carbon comes into contact with the water and can achieve adsorption and purification, thus improving the degree of adsorption and purification of the water by the activated carbon.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A water purifier with upper and lower meshes includes an insulated cover, an upper filter, and a lower filter. The insulated cover is detachably connected to the upper filter and is sealed to the upper filter via an inner insulation ring. The lower filter is detachably connected to the upper filter and is sealed to the upper filter. The upper filter includes an upper cylinder with an upper bottom at its lower part, and mesh holes are provided on both the upper cylinder and the upper bottom. The lower filter includes a lower cylinder with a lower bottom at its bottom, and mesh holes are provided on both the lower cylinder and the lower bottom. An outer insulation ring is provided around the upper filter. The lower cylinder contains a first activated carbon.

[0009] Furthermore, the heat-insulating cover is located at the top of the upper filter, and the lower filter is located at the bottom of the upper filter; the heat-insulating cover, the upper filter, and the lower filter are all coaxially arranged.

[0010] Furthermore, the bottom of the lower cylinder is detachably connected to the bottom of the upper cylinder, and the mesh hole on the bottom of the upper cylinder connects the interior of the upper cylinder and the interior of the lower cylinder; the axial length of the upper cylinder is greater than the axial length of the lower cylinder.

[0011] Furthermore, the bottom of the upper cylinder is provided with an upper thread, and the top of the lower cylinder is provided with a lower thread. The upper thread and the lower thread are screwed together to connect the upper cylinder and the lower cylinder.

[0012] Furthermore, the inner insulation ring is located at the lower part of the insulation cover, and the outer periphery of the inner insulation ring is provided with an upper inner lip and a lower inner lip. Both the upper inner lip and the lower inner lip are interference-fitted with the inner wall of the upper cylinder to achieve a seal.

[0013] Furthermore, the top periphery of the upper cylinder is provided with a flange, which corresponds to the annular stepped surface in the middle of the heat insulation cover.

[0014] Furthermore, an outer insulation ring is provided around the outer periphery of the upper cylinder, and the outer insulation ring is located near the flange; the outer insulation ring includes an upper lip and a lower lip.

[0015] Furthermore, the upper cylinder contains a second activated carbon, which is in the form of strips.

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

[0017] The structure of the water filter for the water cup has been improved by adding a removable filter to the bottom of the original filter, forming a double-layer filter. The lower filter is filled with activated carbon, which is kept away from the heat preservation cover. This ensures that the water can be purified by the activated carbon during pouring. When the water in the cup reaches a certain amount, the activated carbon in the lower filter comes into contact with the water, thus achieving adsorption and purification and improving the degree of adsorption and purification of the water by the activated carbon.

[0018] Meanwhile, if higher water purification requirements are needed, the upper filter can also provide space for activated carbon, allowing for full adsorption and purification of the double-layer activated carbon in the upper and lower filters during the water pouring process.

[0029] The upper filter 3 includes an upper cylinder 31, and an upper cylinder bottom 33 is provided at the lower part of the upper cylinder 31. Both the upper cylinder 31 and the upper cylinder bottom 33 are provided with mesh holes 34.

[0031] An outer insulation ring 4 is provided around the upper filter 3; the outer insulation ring 4 is used to achieve a sealed connection between the upper filter 3 and the inner wall of the open water cup, realize the positioning of the water filter, and at the same time have a heat preservation effect.

[0032] The lower cylinder 51 contains a first activated carbon, which is used to adsorb impurities in the water to purify the water. The first activated carbon can be in granular or strip form.

[0033] The heat-insulating cover 1 is located on top of the upper filter 3, and the lower filter 5 is located at the bottom of the upper filter 3, that is, the lower filter 5 is located at the end of the upper filter 3 away from the heat-insulating cover 1; the heat-insulating cover 1, the upper filter 3 and the lower filter 5 are all coaxially arranged, which conforms to the structure of a common open-mouthed water cup.

[0034] The bottom of the lower cylinder 51 is detachably connected to the bottom of the upper cylinder 31. The mesh hole 34 on the bottom of the upper cylinder 33 connects the inside of the upper cylinder 31 and the inside of the lower cylinder 51. That is, water in the upper cylinder 31 can flow into the lower cylinder 51 through the mesh hole 34 on the bottom of the upper cylinder 33. The axial length of the upper cylinder 31 is greater than the axial length of the lower cylinder 51.

[0035] The bottom of the upper cylinder 31 is provided with an upper thread 35, and the top of the lower cylinder 51 is provided with a lower thread 54. The upper thread 35 and the lower thread 54 are screwed together to connect the upper cylinder 31 and the lower cylinder 51 by thread; that is, the lower cylinder 51 can be disassembled and assembled relative to the upper cylinder 31 by rotation.

[0036] The inner insulation ring 2 is located at the lower part of the insulation cover 1. The outer periphery of the inner insulation ring 2 is provided with an inner upper lip 21 and an inner lower lip 22.

The outer insulation ring 4 includes an upper outer lip 41 and a lower outer lip 42. The upper outer lip 41 and the lower outer lip 42 form a multi-stage insulation seal and a stable position for the entire water filter.

[0039] The upper cylinder 31 contains a second activated carbon, which is in the form of strips. The second activated carbon is used to adsorb impurities in the water to purify the water.

[0040] The working principle of this utility model is as follows:

[0041] First, rotate the lower cylinder 51 of the lower filter 5 relative to the upper cylinder 31 of the upper filter 3 to remove it, put the first activated carbon into the lower cylinder 51, and then screw the lower cylinder 51 onto the bottom of the upper cylinder 31.

[0042] If higher water purification is required, the heat insulation cover 1 can be removed and the second activated carbon can be placed into the upper cylinder 31.

[0043] The water filter is then placed into the open cup, so that the outer insulation ring 4 contacts the inner wall of the open cup, thus completing the installation and positioning of the water filter.

[0044] When you need to pour water into the cup, remove the heat preservation cover 1 from the top of the upper cylinder 31 of the upper filter 3, and pour water into the upper cylinder 31. When the water is poured into the upper cylinder 31, it will come into contact with the second activated carbon. At this time, the second activated carbon can adsorb and purify the water flow.

[0045] The water then flows through the mesh hole 34 into the water cup or into the lower cylinder 51 of the lower filter 5. When it flows into the lower cylinder 51, it comes into contact with the first activated carbon, which then adsorbs and purifies the water.

[0046] The lower filter 5 is placed at the bottom of the upper filter 3, so that the first activated carbon in the lower filter 5 is far away from the heat preservation cover 1. Therefore, when the water filter is placed in an open water cup, the lower filter 5 can be located in the middle or lower part of the inner side of the open water cup.

[0047] In this state, if the water level in the open cup reaches or exceeds the middle level, it can continuously contact the first activated carbon in the lower filter 5. Therefore, after pouring water into the open cup, the water in the open cup can be continuously purified.
