Description

Technical Field

[0001] The utility model relates to the technical field of filtration, and in particular to a gravity water purifier kettle and a filter element thereof. Background Art

[0002] A gravity-fed water purifier is a simple and easy-to-use water purification device that uses gravity to filter water based on the principles of physical filtration and adsorption. It is commonly used in homes, offices, and other settings. In the prior art, the filter element of a gravity-fed water purifier generally uses a multi-layer filter material design, such as clay, activated carbon, palm shells, etc., which can remove odor, color, organic pollutants, and particulate matter from the water. The basic working process is as follows: water first passes through the first layer of filter material in the filter, such as clay, to remove large particles and sediment from the water. Next, the water enters the second layer of filter material, such as activated carbon, which has a large number of micropores and adsorbents on its surface that can absorb harmful substances and odors in the water. Finally, the water passes through the last layer of filter material, such as palm shells, to remove harmful substances such as microorganisms and bacteria in the water, making it safe to drink.

[0003] Gravity-type water purifiers that use a multi-layer filtration structure have difficulty achieving satisfactory filtration results because the filtration layer is essentially composed of particulate matter and the water flow rate is relatively fast. For example, publication number CN109005663B discloses a filter element and a gravity water purifier, wherein the filter element includes: a filter element body, with a water outlet at the lower end; and a flow restrictor cap installed at the lower end of the filter element body and covering the water outlet, and the flow restrictor cap is provided with a flow restrictor connected to the water outlet; the flow restrictor is smaller than the water outlet. This technical solution aims to reduce the water outlet speed of the filter element by limiting the inlet opening, but the above-mentioned problems still exist. Utility Model Content

[0030] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any way. It should be noted that a person skilled in the art may make various variations and improvements without departing from the scope of the present invention. Such variations and improvements are all within the scope of protection of the present invention. Example

[0031] This embodiment provides a gravity water purification filter element mainly used in a filter pot, such as Figure 1-6As shown, the filter cartridge 100 includes a core 200 for filtering water and a filter cartridge 100 for placing the core 200 .

[0032] The filter cartridge 100 primarily comprises a trough-shaped, open-top body 120 and a lid 110 that covers the opening of the body 120. The lid 110 is provided with multiple sets of water inlet holes 111 arranged in an array. In this embodiment, the diameters of the water inlet holes 111 are designed to be smaller in the middle and larger at the edges. Specifically, the diameters of the water inlet holes 111 in the middle of the lid 110 are smaller than those at the edges. This structural design effectively accommodates the static pressure distribution of the water column within the upper filter pot's raw water compartment, which decreases from the middle toward the edges, ensuring uniform water inflow. In some embodiments, a non-woven fabric layer 300 is further included. The edges of the non-woven fabric layer 300 are positioned on a platform of the body 120, and the lid 110 presses the non-woven fabric layer 300 against the body 120. Water entering through the water inlet holes 111 of the lid 110 undergoes primary filtration through the non-woven fabric layer 300 before flowing into the cavity of the core 200. The non-woven fabric 300 can not only further improve the filtering effect, but also improve the distribution uniformity of the incoming water. The bottom plate of the box body 120 is provided with a water outlet 121, which is a circular water outlet hole that can effectively receive filtered water from all directions.

[0033] The outer shape of the core 200 matches the groove structure of the box body 120, and its internal structure is a honeycomb structure formed by multiple independent cavities. The cavity of the core 200 includes a water filtering cavity 210 and a water outlet cavity 220, wherein the structure of the water filtering cavity 210 and the water outlet cavity 220 is a polygonal column structure in this embodiment, as shown in FIG. Figure 4-5As shown. The top of the water filter chamber 210 is open, and its bottom is closed. The bottom of the water outlet chamber 220 is open, and its top is closed. The water filter chamber 210 and the water outlet chamber 220 are in close contact and arranged in a certain manner to form a honeycomb structure. After connection and formation, each water outlet chamber 220 forms a common wall structure with at least two water filter chambers 210, and at least one wall surface of each water filter chamber 210 forms a common wall surface with the water outlet chamber 220. The so-called common wall surface is the filter surface 201 used for water filtration. In this embodiment, the water filter chambers 210 are arranged in parallel rows to form a water filter chamber row 202, and the water outlet chambers 220 are arranged in parallel rows to form a water outlet chamber row 203. The two rows of water filter chamber rows 202 are sandwiched by a second water filter chamber row 203. At this time, the open end of the water filter chamber 210 is substantially flush with the closed end of the water outlet chamber 220, and the closed end of the water filter chamber 210 is substantially flush with the open end of the water outlet chamber 220. In this structure, each water filter chamber 210 basically maintains four filtering surfaces 201 formed with the four surrounding water outlet chambers 220, thereby improving filtration efficiency. In some embodiments, the water filter chamber 210 includes a first water filter chamber 211 and a second water filter chamber 212. The first water filter chamber 211 is a pentagonal prism, the second water filter chamber 212 is a hexagonal prism, and the water outlet chamber 220 is also a hexagonal prism. There are two first water filter chamber rows formed by the first water filter chamber 211, which are located on both sides of the core 200 respectively. The second water filter chamber row formed by the second water filter chamber 211 is located between the two first water filter rows. There is a water outlet chamber row 203 sandwiched between the first water filter chamber row and the second water filter chamber row, as well as between the second water filter chamber rows. Under this structure, a core 200 that is basically completely similar to a honeycomb structure can be formed, thereby improving space utilization and enhancing filtration efficiency. Furthermore, the formation of the water outlet chamber row 202 is formed by the water outlet chamber 220 and the water filter chamber 210, so that the periphery of a water outlet chamber 220 is entirely the water filter chamber 210. Refer to the attached Figure 4-5 As shown, the six walls of the water outlet cavity 220 of the hexagonal prism structure form a common wall structure with the peripheral water filtering cavity 210. In this structural case, the water intake efficiency can be further improved, thereby effectively improving the filtering efficiency.

[0034] The gravity water purification filter cartridge provided in this embodiment operates as follows: The cartridge body 200 is placed within the housing 120, with the outer wall of the cartridge body 200 closely contacting the inner wall of the housing 120, and the open end of the filtration cavity 210 and the closed end of the water outlet cavity 220 located at the upper end. The cartridge cover 110 is then closed and connected to the housing 120. After the cartridge is placed in a predetermined position within the filter pot, the raw water compartment is located above the cartridge, and the purified water compartment is located below the cartridge. After a predetermined amount of raw water is poured into the filter pot, the raw water enters the box body 120 through the water inlet hole 111 and enters the cavity through the open end of the water filter chamber 210. Under the action of the static pressure formed by gravity, the raw water in the water filter chamber 210 is filtered through the filter surface 201 and into the water outlet chamber 220 to form clean water. The filtered clean water flows out through the open end of the water outlet chamber 220 and converges to the water outlet hole 121. It flows through the water outlet hole 121 into the clean water compartment of the filter pot for drinking. The gravity water purification filter element provided in this embodiment forms a honeycomb structure core body in which the raw water enters from the upper end, is filtered through the side wall, and then flows out from the lower end. Compared with the layered filter structure, it achieves full filtration, effectively improving the filtration quality. In addition, the side filter structure effectively increases the filtration area, ensuring the filtration efficiency. Example

[0035] This embodiment 2 is a variation of embodiment 1. By changing the core cylindrical structure cavity to a pyramidal structure cavity, the area of ​​the raw water inlet is greatly increased, thereby effectively improving the filtration efficiency. It further simplifies the core manufacturing process and reduces the manufacturing cost. Specifically:

[0036] like Figure 7 As shown, the structure of the water filter chamber 210 is a quadrangular pyramid, with two opposing faces of the water filter chamber 210 being parallel triangular faces, and the other two opposing faces being inclined faces connected at the bottom to form a fixed angle. That is, the vertical cross-section of the water filter chamber 210 is V-shaped, and the inner cavity of the water filter chamber 210 has a V-shaped groove structure. The water filter chambers 210 are closely arranged with the upper end inlet faces located in the same horizontal plane. After close arrangement, the triangular walls of two adjacent water filter chambers 210 in the longitudinal direction serve as the shared wall surfaces of the two water filter chambers 210. The water outlet chamber 220 is located between the inclined faces of two adjacent water filter chambers 210 in the transverse direction, and between the inclined faces of the water filter chambers 210 at the edges and the wall surface of the core 200. The shape of the water outlet chamber 220 is basically an inverted V. With this structure, the upper end of the core 200 essentially entirely serves as the open end of the water filtration chamber 210, also known as the water inlet end, while the lower end essentially entirely serves as the open end of the water outlet chamber 220. This structurally eliminates the area occupied by the closed end of the water outlet chamber 220, effectively increasing the water inlet rate and thus improving filtration efficiency. Furthermore, the core formed with a V-groove cavity structure eliminates the need to seal the bottom of the water filtration chamber and the top of the water outlet chamber 220, effectively reducing manufacturing costs.

[0037] In this embodiment, a water filter chamber 210 and a water outlet chamber 220 with a V-shaped groove structure are formed by the corrugated filter plate 204 and the partition plate 205. The corrugated filter plate 204 is a single filter plate folded into multiple V-shaped continuous structural plates. A partition plate 205 is sandwiched and connected between two corrugated filter plates 204. In this case, the partition plate 205 serves as the triangular side of the water filter chamber 210. After the corrugated filter plate 204 and the partition plate 205 are connected and placed as a whole within the frame of the core 200, the partition plate 205 and the ends of the corrugated filter plate 204 are connected and fixed to the inner walls of the left and right side panels of the core 200. The outer side surfaces of the corrugated filter plates 204 on both sides are connected and fixed to the inner wall surfaces of the front and rear side panels of the core 200. The corrugated filter plates and partition plates form a V-shaped quadrangular pyramid structure, which is simple in process and easy to operate, further reducing the production cost of the core.
