[0002] Generally, the inside of a water purifier filter element is KDF and activated carbon. The filter element is used to clean the polluted water to the state required for production and living, that is, to make the water reach a certain cleanliness, remove solid particles in the water, kill bacteria, and filter out harmful chemical components. Most of the existing water purifier filter elements and bottom covers are installed on the purification box through bolts, and it takes a long time to disassemble and replace the filter element during maintenance, which is rather troublesome.

[0003] Moreover, usually a gasket needs to be set between the filter element and the mounting frame of the filter element. The gasket will release harmful substances when soaked in water for a long time, and it is also easy to hide dirt and grime in the groove where the gasket is installed. In addition, the gasket belongs to consumables, which also increases the maintenance cost of the equipment. Therefore, how to make the filter element easier to install and disassemble and cleaner at the same time has become an urgent technical problem in this field.

[0004] In view of this, a new water purification equipment filter element and water purification equipment are proposed in this field to solve the existing problems. Summary of the Utility Model

[0011] In the specific implementation of the filter element of the above water purification device, along the installation direction and the disassembly direction of the filter element, a first guiding inclined surface and a second guiding inclined surface are respectively provided on the mounting protrusion, and the first guiding inclined surface and the second guiding inclined surface can abut against the side wall of the clamping groove after the mounting protrusion is clamped into the clamping groove.

[0012] In the specific implementation of the filter element of the above water purification device, the clamping groove includes multiple sections arranged at intervals, and correspondingly, multiple mounting protrusions are provided. The multiple mounting protrusions can be respectively clamped in the multiple clamping grooves. The length of the bottom wall of the clamping groove is less than the length of the top opening, so that the clamping groove is in an inverted trapezoid shape, and the mounting protrusion can slide out of the clamping groove along the inclined side wall of the clamping groove.

[0013] In the specific implementation of the filter element of the above water purification device, a stepped mounting table is provided on the base, and correspondingly, a stepped mounting portion is provided on the housing.

[0028] First, the existing water purifier filter element is described.

[0029] The filter element of a water purifier generally contains KDF and activated carbon. The filter element is used to purify polluted water to the state required for production and life, that is, to make the water reach a certain degree of cleanliness. It removes solid particles in the water, kills bacteria, and filters out harmful chemical components. Most of the existing water purifier filter elements and bottom covers are installed on the purification box by bolts. It takes a long time to disassemble and replace the filter element during maintenance and replacement, which is more troublesome. Moreover, when installing the filter element, it is usually necessary to set a sealing gasket between the filter element and the filter element mounting frame. The sealing gasket will precipitate harmful substances when immersed in water for a long time, and it is easy to hide dirt in the groove where the sealing gasket is installed. In addition, the sealing gasket is a consumable item, which also increases the maintenance cost of the equipment. Therefore, how to make the filter element easier to install and disassemble and easier to clean has become a technical problem that needs to be solved in this field. For this reason, the following implementation method is proposed.

[0030] Embodiment 1

[0031] like Figures 1 - 5As shown in the figure, to solve the problem that the installation and disassembly of the filter element 11 of the existing water purification device 1 are inconvenient and not conducive to cleaning, the water purification device 1 of the present utility model includes a water tank 12 and a filter element 11 placed inside the water tank 12. An installation frame 121 for installing the filter element 11 is provided in the water tank 12. The installation frame 121 is circular ring-shaped, and the circular ring-shaped installation frame 121 is arranged at the bottom of the water tank 12. The filter element 11 includes a housing 111 and a base 112. A stepped installation platform 1122 is provided on the base 112, and a stepped installation portion 1111 is provided on the housing 111. The housing 111 and the base 112 are installed by welding between the installation portion 1111 and the installation platform 1122. An installation protrusion 1121 is provided on the outer side wall of the base 112. An arched gap is provided between the installation protrusion 1121 and the nearby base 112. The installation protrusion 1121 protrudes outward from the direction of the base 112 to the direction of the installation frame 121 and abuts against the inner side wall of the installation frame 121 in an interference fit manner. Along the installation direction of the filter element 11 (i.e., the downward direction), a guiding inclined surface 11211 is provided on the installation protrusion 1121. The guiding inclined surface 11211 can abut against the inner side wall of the installation frame 121 when the installation protrusion 1121 is installed on the installation frame 121. The interior of the filter element 11 includes a filtering element 113. The filtering element 113 is arranged inside the housing 111 and placed on the base 112. A plurality of installation strips 1123 protrude from the base 112. An installation groove 1124 is defined among the plurality of installation strips 1123. The filtering element 113 is installed in the installation groove 1124 to fix the filtering element 113.

[0032] In the case of adopting the above-mentioned implementation manner, during the installation process of the filter element 11 of the present utility model, first, the filter element 11 assembled from the housing 111 and the base 112 is placed into the circular ring-shaped installation frame 121 from top to bottom. During this process, since the guiding inclined surface 11211 is provided on the installation protrusion 1121, the guiding inclined surface 11211 first contacts the inner side wall of the installation frame 121. Continuing to push the filter element 11 downward, the inner side wall of the installation frame 121 generates a certain extrusion force on the guiding inclined surface 11211. Since an arched gap is provided between the installation protrusion 1121 and the nearby base 112, the connection area between the nearby base 112 and the installation protrusion 1121 is reduced. Thus, the installation protrusion 1121 can undergo a large degree of deformation under the extrusion of the installation frame 121. At the same time, the filter element 11 slides into the circular ring-shaped installation frame 121 under the guiding action of the guiding inclined surface 11211, and the installation protrusion 1121 abuts against the inner side wall of the installation frame 121, realizing the installation of the filter element 11 and the installation frame 121. When disassembling the filter element 11, only need to drag the filter element 11 upward to pull the filter element 11 out of the installation frame 121.

[0033] The advantages of the above setting method are as follows: Since the filter element 11 of the present utility model is connected to the mounting frame 121 by abutting, it is convenient to operate during installation and disassembly. Moreover, since there is no gasket and the groove for placing the gasket is not provided as in the prior art, the connection between the installation protrusion 1121 and the mounting frame 121 is relatively smooth, avoiding dirt accumulation in the groove, reducing the cleaning task of the filter element 11, and also avoiding the harmful substances precipitated due to the aging of the gasket, reducing the maintenance cost of the equipment, and solving the problem that the installation and disassembly of the filter element 11 of the existing water purification equipment 1 are inconvenient and not conducive to cleaning. In addition, by providing an installation groove 1124 for placing the filter element 113 on the base 112, the installation and fixation of the filter element 113 are realized, and the structure is simple and easy to process. In addition, regarding the shape of the mounting frame 121, those skilled in the art can set it to other common shapes such as square, as long as it can satisfy the abutting connection with the installation protrusion 1121. These changes do not exceed the technical principle of the present utility model, so they will also be included in the protection scope of the present utility model.

[0034] The main implementation manners of the present utility model have been introduced above. Next, some preferred implementation manners of the present utility model will be introduced.

[0035] Embodiment 2

[0036] In a possible implementation manner, a clamping groove (not shown in the figure) is provided on the inner side wall of the circular mounting frame 121. The installation protrusion 1121 can be clamped in the clamping groove to realize the installation of the filter element 11 and the water tank 12. The clamping groove includes multiple sections arranged at intervals. Correspondingly, multiple installation protrusions 1121 are provided. The multiple installation protrusions 1121 can be respectively clamped in the multiple clamping grooves. The length of the bottom wall of the clamping groove is less than the length of the top opening, so that the clamping groove is in an inverted trapezoid shape. Thus, the two side walls in the length direction of the clamping groove are inclined (the length direction of the clamping groove refers to the horizontal direction according to the Figure 4 orientation in the figure), and the installation protrusion 1121 can slide out of the clamping groove along the inclined side wall of the clamping groove.

[0037] In the case of adopting the above-mentioned implementation manner, during the installation process of the filter element 11 of the present utility model, after the installation protrusion 1121 on the filter element 11 enters the interior of the installation frame 121, continue to push the filter element 11 downward so that the installation protrusion 1121 enters the card slot on the inner side wall of the installation frame 121. Since the installation protrusion 1121 abuts against the inner side wall of the installation frame 121 in a deformed state before entering the card slot, when the installation protrusion 1121 enters the card slot, the installation protrusion 1121 will return from the original deformed state to the initial state. Thus, the upper and lower side surfaces of the installation protrusion 1121 can be clamped in the card slot, restricting the up and down movement of the filter element 11 in the installation frame 121, thereby realizing the installation and fixation between the filter element 11 and the installation frame 121. When disassembling the filter element 11, since the two side walls in the length direction of the card slot are inclined, only need to rotate the filter element 11 to drive the installation protrusion 1121 to rotate together. When the installation protrusion 1121 rotates to the inclined side wall of the card slot, the installation protrusion 1121 can move along the inclined side wall of the card slot and deform under the extrusion of the inclined side wall. The end of the inclined side wall of the card slot is connected to the inner side wall of the installation frame 121. Thus, the installation protrusion 1121 can rotate along the inclined side wall of the card slot to the inner side wall of the installation frame 121 and abut against the inner side wall, and then drag the filter element 11 upward to disassemble the filter element 11 from the interior of the installation frame 121.

[0038] The advantages of the above setting method are as follows: Compared with the previous implementation manner in which the installation between the filter element 11 and the installation frame 121 is achieved only by the abutment of the installation protrusion 1121 and the inner side wall of the installation frame 121, in this implementation manner, a card slot for fixing the installation protrusion 1121 in the vertical direction is added, further enhancing the stability of the connection between the filter element 11 and the installation frame 121. In addition, by setting the card slot in multiple sections and setting the two side walls in the length direction of the card slot to be inclined, it is also convenient for the disassembly of the filter element 11.

[0039] Embodiment Three

[0040] In the first-mentioned embodiment one, along the installation direction of the filter element 11, a guiding inclined surface 11211 is provided on the installation protrusion 1121. In the second-mentioned embodiment two, a scheme is proposed in which the card slots on the inner side wall of the installation frame 121 are set in multiple sections, and the two side walls in the length direction of the card slot are set to be inclined. Different from the previous embodiments, in this implementation manner, along the installation direction and the disassembly direction of the filter element 11, a first guiding inclined surface (i.e., the guiding inclined surface 11211 in Embodiment One) and a second guiding inclined surface are respectively provided on the installation protrusion 1121. The first guiding inclined surface and the second guiding inclined surface can abut against the side walls in the width direction of the card slot after the installation protrusion 1121 is clamped into the card slot (the width direction of the card slot refers to Figure 4In the vertical direction of the middle azimuth), at the same time, the card slot can be set as a whole section or multiple sections. If the card slot is multiple sections, the two side walls in the length direction of the card slot can be set in an inclined or non-inclined form.

[0041] In the case of adopting the above-mentioned implementation manner, during the installation process of the filter element 11 of the present utility model, it is similar to the second embodiment described above. The difference is that after the installation protrusion 1121 reaches the position of the card slot, it does not entirely enter the interior of the card slot, but abuts against the side wall of the card slot through the first guiding inclined surface and the second guiding inclined surface. In this way, it can also play a role in restricting the movement of the installation protrusion 1121 in the vertical direction. During the disassembly process of the filter element 11, due to the existence of the second guiding inclined surface on the installation protrusion 1121, when the filter element 11 is dragged upward, the installation protrusion 1121 can slide out of the card slot under the guiding action of the second guiding inclined surface, thereby realizing the disassembly of the filter element 11. By setting the first guiding inclined surface and the second guiding inclined surface, while making the installation connection between the filter element 11 and the installation frame 121 more stable, the purpose of convenient disassembly is also achieved.

[0042] It should be noted that the above-mentioned implementation manner is only used to illustrate the principle of the present utility model and is not intended to limit the protection scope of the present utility model. Under the condition of not deviating from the principle of the present utility model, those skilled in the art can adjust the above structure so that the present utility model can be applied to more specific application scenarios.

[0043] In addition, the present utility model also provides a water purification device 1, and the water purification device 1 has the filter element 11 of the water purification device 1 mentioned in any of the above implementation manners.

[0044] So far, the technical solution of the present utility model has been described in combination with the preferred implementation manners shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific implementation manners. Under the premise of not deviating from the principle of the present utility model, those skilled in the art can make equivalent changes or replacements to the relevant technical features, and the technical solutions after these changes or replacements will all fall within the protection scope of the present utility model.
