Description

Technical Field

[0001] The utility model belongs to the field of water purification filter elements, and in particular relates to a filter element and a pet water dispenser. Background Art

[0002] Currently, the pet drinking fountains on the market consist of two parts: a water supply system and a filter element, among which the filter element plays the role of filtering and purifying drinking water.

[0003] Common filter elements are usually composed of filter cotton filled with activated carbon or ion resin. The filter element is installed in the water dispenser to filter the water source for direct drinking by pets. The filtering effect of such filter elements is poor, mainly because pets shed a lot of hair, and pet saliva is mixed with hair, food residues, and indoor dust and sand and other impurities. During the pet's drinking process, the circulating water in the pet water dispenser is secondary polluted, and impurities such as food residues, sand, and hair may be scattered on the surface of the filter element, affecting the water purification effect of the filter element and reducing the service life of the filter element. Utility Model Content

[0004] The technical purpose of the utility model is to provide a water dispenser filter element, aiming to solve the problem that the pet water dispenser filter elements currently on the market cannot collect impurities such as pet hair and food residues, resulting in poor water purification effect of the filter element.

[0005] To solve the above technical problems, the utility model is implemented as follows: a filter element is used for filtering drinking water in a pet drinking fountain;

[0006] The filter element comprises a plurality of stacked filter layers, and along the stacking direction of each of the filter layers, the first side of the filter element is the water inlet side, and the second side of the filter element is the water outlet side;

[0007] A groove is provided on at least the outermost filter layer close to the first side of the filter element, and the groove is used to receive suspended matter and sediment left after the drinking water passes through the filter layer;

[0008] Except for the outermost filter layer, at least one filter layer is filled with a filter medium, and the filter medium includes an ion exchange resin and a variety of porous adsorption materials.

[0009] Furthermore, the porous adsorption material includes activated carbon and medical stone.

[0010] Furthermore, a plurality of trough bodies are integrally formed on the filter layer, and each trough body is filled with the ion exchange resin, the activated carbon and the medical stone respectively.

[0011] Furthermore, each of the trough bodies is evenly spaced and arranged on the filter layer, at least one of the trough bodies overlaps with the groove, and the trough body overlapping with the groove is filled with the activated carbon.

[0012] Furthermore, the outermost filter layer of the filter element is filter cotton.

[0013] Furthermore, the filter cotton is circular, the bottom of the groove is circular, and the groove is arranged at the center of the filter cotton.

[0014] Furthermore, the groove wall of the groove expands outward from the groove bottom to the groove opening.

[0015] Furthermore, a filter screen matching the groove is detachably arranged in the groove.

[0016] Furthermore, the filter element is provided with a through hole extending from the water inlet side to the water outlet side, and the through hole is used for allowing the pipeline of the water supply system to pass through.

[0017] The utility model also provides a pet drinking fountain, comprising a water supply system and the filter element as described above, wherein the water supply system is connected to the filter element, and the water supply system is used to drive the drinking water to circulate from the water inlet side to the water outlet side of the filter element.

[0018] Compared with the prior art, the filter element and pet drinking fountain in the utility model have the following beneficial effects: the filter element includes multiple filter layers, and at least the outermost filter layer close to the first side of the filter element is provided with a groove, and the groove can accommodate suspended matter and sediment left after the drinking water passes through the filter layer, such as pet hair, food residues, mud and other solid suspended matter or sediment. These suspended matter and sediment are collected in the groove and will not cover the surface of other positions of the filter layer, thereby avoiding the suspended matter and sediment affecting the water purification effect of the filter element.

[0019] In addition to the outermost filter layer, at least one filter layer is filled with filter media, which includes at least two of ion exchange resin, porous adsorption material and separation membrane. These filter media can absorb micron- to millimeter-level impurities in drinking water, soften water and remove odors in drinking water, achieving a further filtering effect. Compared with the pet water dispenser filter element currently on the market, it has more filtering times, and filters in layers according to the size of impurities, which has a better filtering effect, reduces filter element blockage, and increases the service life of the filter element.

[0032] Example:

[0033] like Figures 1 to 7 As shown, in this embodiment, a filter element is used for filtering drinking water in a pet drinking fountain;

[0034] The filter element comprises a plurality of stacked filter layers 1, and along the stacking direction of each filter layer 1, the first side of the filter element is the water inlet side, and the second side of the filter element is the water outlet side;

[0035] A groove 111 is provided on at least the outermost filter layer 1 close to the first side of the filter element, and the groove 111 is used to receive suspended matter and sediment left after the drinking water passes through the filter layer 1;

[0036] Except for the outermost filter layer 1 , at least one filter layer 1 is filled with a filter medium 2 , and the filter medium 2 includes an ion exchange resin 21 and a variety of porous adsorption materials.

[0037] A filter element configured in this way has a multi-layered filter layer 1 structure, which can at least form three levels of filtration, namely, a first layer, a second layer and a third layer.

[0038] First layer filtration: at least the outermost filter layer 1 close to the first side of the filter element. This filter layer 1 is arranged on the water inlet side of the filter element, and a groove 111 is arranged on the filter layer 1, which can accommodate the suspended matter and sediment left after the drinking water passes through the filter layer 1.

[0039] It can be understood that suspended matter usually refers to solid particles suspended in water, and the particle size is usually between a few microns and a few millimeters. Such solid particles will not settle by themselves but will be suspended in the water. Usually, sedimentation refers to the process in which solid particles can settle in water and settle on the bottom of the water or the bottom of the container. Sedimentation usually comes from the sedimentation of suspended matter. In a pet drinking fountain, suspended matter is generally pet hair and food residues, etc., and sediment is mostly mud and sand. When the pet drinking fountain is working, the drinking water to be purified in the water tank will be driven by a water pump through the filter element, and suspended matter and sediment will reach the groove 111 with the flow of the drinking water to be purified and adhere to the groove 111, and will not be deposited on the bottom of the water tank of the pet drinking fountain.

[0040] Therefore, the first layer of adsorption plays a role in collecting solid suspended matter or sediments of several microns to several millimeters, avoiding the solid suspended matter or sediments from clogging the surface of other positions of the filter layer 1, and improving the water permeability and water purification effects of the filter element.

[0041] Second layer filtration: except for the outermost filter layer 1, at least one filter layer 1 is filled with a filter medium 2, and the filter medium 2 includes an ion exchange resin 21 and a porous adsorption material.

[0042] The ion exchange resin 21 can remove cations in the drinking water to be purified by adsorption and ion exchange. For example, the cation exchange resin 21 contains a large number of anions with fixed negative charges, which will exchange ions with the cations with positive charges in the drinking water to be purified. Through ion exchange, the cation exchange resin 21 can effectively remove cations in the drinking water to be purified, such as sodium ions, magnesium ions and calcium ions, thereby achieving the purpose of softening and purifying the drinking water.

[0043] Porous adsorption materials include activated carbon 22, porous ceramics, nano silver particles or porous natural minerals. Porous adsorption materials can adsorb organic matter in drinking water, remove odor, pigments and harmful gases in water, and can also remove residual chlorine and some heavy metal ions in water, such as lead, mercury, etc., to improve the taste and quality of drinking water. Among them, porous natural minerals can be silicate minerals with porous structures, such as medical stone 23. Porous natural minerals also have a certain alkalinity, which can be used to adjust the pH value of drinking water. Moreover, most natural minerals contain a variety of mineral elements, which can increase the nutritional content in drinking water.

[0044] Therefore, the second layer of adsorption can play a variety of filtering roles, such as softening drinking water, removing residual chlorine, adsorbing heavy metal ions, adjusting the pH value of drinking water, and increasing the nutritional content of drinking water.

[0045] The third layer of filtration: the second side of the filter element is the water outlet side. Except for the outermost filter layer 1, at least one filter layer 1 is filled with filter medium 2, that is, the outermost filter layer 1 on the second side of the filter element is not filled with filter medium 2.

[0046] The outermost filter layer 1 on the second side of the filter element can be provided with the same or different filter material as the outermost filter layer 1 on the first side of the filter element. Its function is to perform the third layer of filtration on drinking water, and it can also serve to assist in fixing various filter media 2 in the second layer of filtration.

[0047] It can be understood that the first layer of filtration, the second layer of filtration and the third layer of filtration mentioned above only represent that the filter element can achieve three levels of filtration effects, and the filter layer 1 of the filter element does not have only three layers. The filter layer 1 of the filter element includes at least the outermost layers on both sides. Different numbers of layers can be set according to specific water purification requirements. This application does not limit the number of filter layers 1.

[0048] The filter medium 2 can be arranged in the same filter layer 1 or in different filter layers 1 .

[0049] like Figure 1 As shown, in the first embodiment, three different filter media 2 are evenly spaced and arranged in the same filter layer 1. Preferably, the three filter media 2 are arranged at the outermost filter layer 1 close to the first side of the filter element. Figure 1 The dotted line portion indicates that multiple filter layers 1 may be added.

[0050] like Figure 2 As shown, in the second embodiment, different from the first embodiment, three filter media 2 are arranged on the outermost filter layer 1 on the first side of the filter element. Such arrangement makes the thickness of the filter element thinner than that of the structure of the first embodiment.

[0051] like Figure 3 As shown, in the third embodiment, three different filter media 2 are stacked in different filter layers 1, and the drinking water to be purified passes through each filter layer 1 in sequence. Compared with the first and second embodiments, the purification area of ​​various filter media 2 on the filter element cross-section through which the drinking water passes reaches more than 90%, and the purification effect is better.

[0052] Furthermore, the porous adsorption material includes activated carbon 22 and medical stone 23 .

[0053] Activated carbon 22 can absorb organic matter in drinking water, remove peculiar smell, pigment and harmful gas in water, and can also remove residual chlorine and some heavy metal ions in water, such as lead and mercury, to improve the taste and quality of drinking water. Medical stone 23 has the ability to absorb heavy metal ions and has a certain alkalinity, which can be used to adjust the pH value of drinking water, and medical stone 23 contains a variety of mineral elements, such as silicon, iron, calcium, etc. Medical stone 23 releases these minerals into water, increasing the nutritional content of water.

[0054] Furthermore, a plurality of tank bodies are integrally formed on the filter layer 1 , and each tank body is filled with an ion exchange resin 21 , activated carbon 22 and medical stone 23 , respectively.

[0055] like Figure 4As shown, three slots are integrally formed on the outermost filter layer 1 on the first side close to the filter element, and the three slots are sequentially filled with ion exchange resin 21, activated carbon 22 and medical stone 23. With such an arrangement, the integral molding manufacturing process is simple and fast, and the filter medium 2 can be fixed on the filter layer 1.

[0056] Furthermore, if Figures 4 to 6 As shown, the grooves are evenly spaced apart on the filter layer 1 , at least one groove overlaps with the groove 111 , and the groove overlapping with the groove 111 is filled with activated carbon 22 .

[0057] The outermost filter layer 1 is thinner at the groove 111, and its supporting force is poor. When the water pump of the pet water dispenser is started, the water flow may cause the filter element to bend at the groove 111, thereby causing the filter element to fail to stably cover the water outlet passage of the pet water dispenser. Figure 4 As shown, the groove body overlapping with the groove 111 is filled with activated carbon 22. This arrangement can not only improve the drinking water purification effect, but also increase the support force and stability of the filter element.

[0058] Furthermore, the outermost filter layer 1 of the filter element is filter cotton.

[0059] The filter layer 1 is usually a filter cotton formed by a combination of cellulose, polyester fiber, glass fiber and other materials, and is prepared by a molding process such as pressing molding. During the preparation, a filter cotton having multiple grooves is formed by a pressing molding process. After the filter medium 2 is filled into a layer of filter cotton, another layer or layers of filter cotton are pressed and molded on the filter cotton filled with the filter medium 2, so that the filter medium 2 can be fixed, with low cost and high production efficiency. Figure 5 and 6 As shown, the outermost filter layers 1 of the filter element are respectively water inlet side filter cotton 11 and water outlet side filter cotton 12.

[0060] Furthermore, the filter cotton is circular, the bottom of the groove 111 is circular, and the groove 111 is arranged at the center of the filter cotton.

[0061] like Figure 4 and 7 As shown, the filter cotton, the bottom of the groove 111 and the position setting of the groove 111 can make the groove 111 collect impurities at different positions more evenly, improve the collection efficiency of suspended matter and sediment in the groove 111, and then improve the filtering efficiency of the filter element.

[0062] Furthermore, the groove wall of the groove 111 expands outward from the groove bottom to the groove opening.

[0063] like Figure 5 As shown, the groove wall of the groove 111 is inclined, which is conducive to the collection of impurities into the groove 111, thereby improving the water purification effect and filtering efficiency of the filter element.

[0064] Furthermore, a filter screen (not shown in the figure) matching the groove 111 is detachably arranged in the groove 111 .

[0065] The filter screen can also be filter cotton of similar material to the filter layer 1. The filter screen can be inserted into the groove 111. By regularly replacing the filter screen, the life of the filter element can be extended. The filter screen has a low cost and can save resources.

[0066] Furthermore, a through hole 3 is provided on the filter element, which passes from the water inlet side to the water outlet side. The through hole 3 is used for the pipeline of the water supply system to pass through.

[0067] Specifically, in one embodiment, if Figure 4 As shown, the through hole 3 is arranged at a non-center of the filter layer 1, and the filter layer 1 is arranged around the through hole 3, and the filter groove is avoided. Since the filter element is designed with a groove 111, suspended matter and sediment will gather in the groove 111 with the flow of drinking water, avoiding the accumulation of suspended matter such as hair in the through hole 3 of the filter element in the traditional filter element, so that the dirt adhesion on the pipe surface of the water supply system in the pet water dispenser is reduced, which is convenient for cleaning the pet water dispenser and replacing the filter element.

[0068] The utility model also provides a pet drinking fountain, comprising a water supply system and the filter element as described above, wherein the water supply system is connected to the filter element, and the water supply system is used to drive the drinking water to circulate from the water inlet side to the water outlet side of the filter element.

[0069] The pet water dispenser configured in this way has good water purification effect, and the filter element as a consumable material has low consumption, which reduces the cost of use. Compared with the traditional pet water dispenser, the filter element can collect impurities such as pet hair and food residues and mud, effectively avoiding filter element clogging and prolonging the service life of the filter element.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
