[0068] Detailed Implementation

[0069] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0070] The water purification device 1000 according to an embodiment of the present invention includes: a housing assembly 100, a water pump assembly 300, a water circuit assembly, and a display assembly 500. The housing assembly 100 is used to install the water pump assembly 300, the water circuit assembly, the display assembly 500, and the filter element assembly, that is, the water pump assembly 300, the water circuit assembly, the display assembly 500, and the filter element assembly are built into the housing assembly 100.

[0071] Specifically, the housing assembly 100 includes an outer shell 10 and a middle shell 20. The outer shell 10 is a hollow frame structure with open upper and lower ends. The middle shell 20 is built inside the outer shell 10 and includes a connecting base shell 21 and a plurality of hollow support columns 22 protruding from the connecting base shell 21 and extending in the vertical direction. The filter element 200 of the filter element assembly is built inside the hollow support columns 22. In other words, the outer shell 10 surrounds the outside of the middle shell 20, and the hollow support columns 22 surround the outside of the filter element 200, thereby isolating the filter element 200 from the outside through the outer shell 10 and the hollow support columns 22.

[0072] During assembly, multiple filter elements 200 of the filter element assembly can be installed one by one into multiple hollow support columns 22, and then the outer shell 10 can be fitted onto the outer shell 20.

[0073] To improve the structural strength of the water purification device 1000 and reduce its space occupation, the inventors made the following improvements to the housing assembly 100 of the water purification device 1000.

[0074] The following reference Figures 1-12 The housing assembly 100 for a water purification device 1000 is described according to some embodiments of the present invention.

[0075] like Figure 1 Combination Figure 3 As shown, the housing 10 of the housing assembly 100 for the water purification device 1000 includes a first sidewall 11, a second sidewall 12, a third sidewall 14, and a fourth sidewall 15 connected end to end. The first sidewall 11 and the second sidewall 12 are positioned relative to a first direction (e.g., ...). Figure 3 The third sidewall 14 and the fourth sidewall 15 are symmetrically arranged relative to the second direction (e.g., in the front and back directions). Figure 3 The first sidewall 11, the second sidewall 12, the third sidewall 14 and the fourth sidewall 15 are symmetrically arranged in the left and right directions, and the connecting points of the first sidewall 11, the second sidewall 12, the third sidewall 14 and the fourth sidewall 15 are smoothly connected. At least two opposite sidewalls of the first sidewall 11, the second sidewall 12, the third sidewall 14 and the fourth sidewall 15 are arc-shaped walls.

[0076] For example, refer to Figure 3 From a top view, the outer shell 10 has an elongated oval structure. The first sidewall 11 and the second sidewall 12 are located on the front and rear sides, and the third sidewall 14 and the fourth sidewall 15 are located on the left and right sides. The first sidewall 11 and the second sidewall 12 can be curved walls, or the third sidewall 14 and the fourth sidewall 15 can be curved walls, or all three can be curved walls. In other words, at least a portion of the walls of the outer shell 10 are curved surfaces, such as arc surfaces. The projection of the outer shell 10 onto the horizontal plane can be an elongated oval, for example, an ellipse.

[0077] Because the first sidewall 11, the second sidewall 12, the third sidewall 14 and the fourth sidewall 15 are smoothly connected, the outer and inner walls of the outer shell 10 are relatively smooth and rounded, which can improve the structural strength of the outer shell 10.

[0078] Of course, the outer shell 10 of the present invention is not limited to the above-described elongated oval structure, and the arcuate wall of the outer shell 10 is not limited to... Figure 3 The curved wall can protrude outwards in a direction away from the center of the outer shell 10, as shown in the diagram. Alternatively, the curved wall can protrude inwards in a direction closer to the center of the outer shell 10.

[0079] Because at least two opposite sidewalls of the outer casing 10 are curved, the outer casing 10 has stronger resistance to deformation, improves its structural strength, is more resistant to external impacts, and increases the service life of the outer casing 10.

[0080] According to an embodiment of the present invention, the housing assembly 100 for a water purification device 1000 can appropriately reduce the horizontal distance of the housing 10 in the first direction and / or the second direction by setting at least two opposite side walls of the housing 10 as arc-shaped walls, thereby making the housing 10 structurally stronger, occupying less space, and allowing the various components of the water purification device 1000 to be compactly arranged inside the housing 10, improving the structural strength of the housing 10 and avoiding hollowing and damage during transportation and handling.

[0081] In optional embodiments, such as Figure 3 As shown, the perimeter of the first sidewall 11 and the second sidewall 12 is greater than the perimeter of the third sidewall 14 and the fourth sidewall 15. In other words, the horizontal distance of the outer shell 10 in the first direction is less than the horizontal distance in the second direction, that is, the outer shell 10 in... Figure 3 The extension distance in the left and right directions is greater than the extension distance in the front and back directions.

[0082] In optional embodiments, such as Figure 1 Combination Figure 3 As shown, the outer surfaces of the first sidewall 11 and the second sidewall 12 are planar, while the surfaces of the third sidewall 14 and the fourth sidewall 15 bulge outwards away from the center of the outer shell 10. In other words, the third sidewall 14 and the fourth sidewall 15 are arc-shaped walls, while the first sidewall 11 and the second sidewall 12 are straight surfaces. From the top view, the outer shell 10 is oblong. That is, part of the wall surface of the outer shell 10 is planar, and the other part is curved. Among them, the third sidewall 14 and the fourth sidewall 15 are located at the left and right ends of the outer shell 10, and the second sidewall 12 and the fourth sidewall 15 are located at the front and rear sides of the middle part of the outer shell 10. Since the third sidewall 14 and the fourth sidewall 15 are arc-shaped walls, they have strong resistance to deformation. The first sidewall 11 and the second sidewall 12 are straight structures, which are relatively stable. The first sidewall 11 and the second sidewall 12 can compensate for each other with the third sidewall 14 and the fourth sidewall 15, thereby better improving the structural stability of the outer shell 10 and preventing the outer shell 10 from deforming excessively.

[0083] In an optional embodiment, refer to Figure 3 The central angle α of the third sidewall 14 and the fourth sidewall 15 is between 30° and 180°. In this embodiment, the "central angle" refers to the angle of the circle corresponding to the cross-section of the third sidewall 14 and the fourth sidewall 15. That is, from the top view direction, the third sidewall 14 and the fourth sidewall 15 can be semicircular or arc-shaped. For example, the central angle of the third sidewall 14 and the central angle of the fourth sidewall 15 can be 30°, 45°, 60°, 90°, 120°, 135°, 150°, or 180°. It can be understood that when the radius of curvature of the third sidewall 14 and the fourth sidewall 15 is fixed, the larger the central angle of the third sidewall 14 and the fourth sidewall 15, the larger the horizontal distance between the first sidewall 11 and the second sidewall 12, and the larger the spatial volume defined by the outer shell 10. Conversely, the smaller the central angle of the third sidewall 14 and the fourth sidewall 15, the smaller the horizontal distance between the first sidewall 11 and the second sidewall 12, and the smaller the spatial volume defined by the outer casing 10. In this way, the size of the outer casing 10 can be adjusted according to the size of the various components that need to be placed, so that the components are arranged in an orderly and compact manner within the outer casing 10.

[0084] In an optional embodiment, refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 The first sidewall 11, the second sidewall 12, the third sidewall 14, and the fourth sidewall 15 form a cavity with open upper and lower ends. The housing assembly 100 also includes a middle shell 20, which is built into the cavity. That is, through the hollow frame structure of the outer shell 10, the cavity can be used to install and position components such as the middle shell 20. In other words, the housing assembly 100 generally includes the outer shell 10 located on the outside and the middle shell 20 located on the inside.

[0085] Specifically, such as Figure 6 , Figure 8 and Figure 9 As shown, the middle shell 20 includes a connecting base shell 21 and a plurality of hollow support columns 22. The outer contour of the connecting base shell 21 matches the inner contour of the outer shell 10, and the connecting base shell 21 has a plurality of clearance through holes 2111 extending through its top and bottom surfaces. The hollow support columns 22 are formed at the bottom of the connecting base shell 21, corresponding to the clearance through holes 2111, and the hollow support columns 22 extend from one side (e.g., Figure 8 The upper side of the middle shell 20) to the other side (such as Figure 8 It extends in the direction of the lower side of the middle shell 20.

[0086] It is understandable that, due to the matching shape and structure of the connecting base shell 21 and the outer shell 10, the inner wall surface of the outer shell 10 and the outer wall surface of the middle shell 20 are better matched and mutually rely on each other to form the shell structure of the shell assembly 100.

[0087] The hollow support column 22 divides the cavity into multiple independent installation and positioning spaces. For example, filter elements, water pumps, or adapters can be placed inside the hollow support column 22. For instance, the filter element can be inserted into the hollow support column 22 through the clearance hole 2111.

[0088] Furthermore, the hollow support column 22 may include one, two, or more, for example, such as Figure 6 As shown in Figure 8, there are two hollow support columns 22, which are arranged side by side with intervals. It should be understood that the above is only illustrative and is not a limitation on the embodiment of the present invention. There can be three hollow support columns 22, which are arranged in a straight line at the bottom of the connecting base shell 21.

[0089] Optional examples, such as Figure 5 Combination Figure 7The projection of the connecting base shell 21 onto the horizontal plane overlaps the projection of the hollow support column 22 onto the horizontal plane. In other words, the outer periphery of the connecting base shell 21 extends beyond the outer periphery of the hollow support column 22. After the inner shell 20 is built into the cavity, the outer surface of the connecting base shell 21 is closer to the inner wall surface of the outer shell 10 than the outer surface of the hollow support column 22.

[0090] Optional examples, such as Figures 6-8 As shown, multiple hollow support columns 22 are spaced apart, and a structural reinforcing member 50 is provided between two hollow support columns 22. The two ends of the structural reinforcing member 50 are respectively connected to the outer peripheral surfaces of the two hollow support columns 22. That is, one end of the multiple hollow support columns 22 (e.g., ...) Figure 8 The upper end of each hollow support column 22 is connected to the connecting base shell 21, and the other end of each hollow support column 22 is connected to the connecting base shell 21. Figure 8 The lower end of each component (including the core) is connected to the structural reinforcement 50. This ensures that even when components such as filter elements are loaded inside the hollow support column 22, various forces can be distributed between the structural reinforcement 50 and the connecting base shell 21, thereby improving the stability of the internal structure of the shell assembly 100. Furthermore, the structural reinforcement 50 can be arched, providing a larger load-bearing surface and further enhancing the structural stability of the shell assembly 100.

[0091] Optional examples, such as Figure 1 Combination Figures 2-3 As shown, the inner wall surface of the outer shell 10 has multiple spaced ribs 19, and the ribs 19 and the inner wall surface of the outer shell 10 form a notch 191. The top of the connecting base shell 21 is provided with a latch 213 that mates with the notch 191. That is, the connection between the outer shell 10 and the middle shell 20 is achieved by the latch 213 engaging with the notch 191.

[0092] The rib 19 can extend along the longitudinal direction of the outer shell 10, such as... Figure 1 As shown, the rib 19 can also extend along the circumferential direction of the outer shell 10, but is not shown in the figure. By providing multiple ribs 19 on the inner circumferential wall of the outer shell 10, the structural strength of the outer shell 10 and its compressive strength can be effectively improved.

[0093] In one specific embodiment, refer to Figure 11 Combination Figure 12 As shown, the latch 213 is located on the outer periphery of the connecting base shell 21 and extends downward. The top surface of the rib 19 is recessed downward to form an upward-opening notch 191, into which the latch 213 is inserted. That is, the latch 213 is inserted into the notch 191 from top to bottom, thereby suspending the middle shell 20 on the outer shell 10. The latch 213 and the notch 191 can be fitted with clearance or interference.

[0094] In a specific example, such as Figure 1Combination Figure 2 As shown, the ribs 19 include multiple ribs, which are distributed on at least one of the first sidewall 11, the second sidewall 12, the third sidewall 14, and the fourth sidewall 15. In other words, the multiple ribs 19 can be formed on the first sidewall 11 and / or the second sidewall 12 and / or the third sidewall 14 and / or the fourth sidewall 15. Preferably, the multiple sets of ribs 19 are evenly distributed on the first sidewall 11, the second sidewall 12, the third sidewall 14, and the fourth sidewall 15. Correspondingly, latches 213 are also evenly distributed on the outer periphery of the connecting base shell 21. Thus, by the corresponding engagement of the multiple latches 213 with the multiple notches 191, the middle shell 20 can be relatively stably disposed within the cavity.

[0095] In addition, the ribs 19 evenly distributed on the inner wall of the outer shell 10 can also enhance the overall strength of the outer shell 10. Preferably, the length of the ribs 19 is approximately the same as the longitudinal length of the wall of the outer shell 10.

[0096] In a further optional example, two protruding ribs 19 form a group, and one latch 213 corresponds to one group of protruding ribs 19. That is, one latch 213 is simultaneously embedded in two notches 191. In this way, the force of the latch 213 can be distributed on the two protruding ribs 19, avoiding the problem of the protruding ribs 19 breaking.

[0097] Further optional examples, such as Figure 4 As shown, the horizontal distance l between two adjacent ribs 19 is between 1.5 and 3.5 mm. The distance between two adjacent ribs 19 is the distance between the side surfaces of one rib 19 and the other. For example, the width of the horizontal distance l can be 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, or 3.5 mm. Of course, the above embodiment is merely illustrative and should not be construed as limiting the scope of protection of this invention. For example, the distance between two ribs 19 can also be less than 1.5 mm or greater than 3.5 mm. That is, the horizontal distance between two ribs can be adjusted accordingly based on changes in the dimensions of the outer casing 10.

[0098] Further optional examples, such as Figure 2 Combination Figure 4 As shown, the rib 19 includes a connecting section 192 and a cylindrical section 193. The connecting section 192 connects the inner wall of the outer shell 10 to the cylindrical section 193, serving to support the middle shell 20 and reinforce the structural strength of the outer shell 10. When the middle shell 20 is inserted into the cavity, the cylindrical section 193 acts as a guide and also abuts against the outer circumferential surface of the middle shell 20, providing a limiting function. Therefore, the dimensions of both the cylindrical section 193 and the connecting section 192 have relatively specific requirements.

[0099] Specifically, such as Figure 2 Combination Figure 4As shown, the radial dimension r of the cylindrical segment 193 is between 1 and 2 mm. For example, the diameter of the cylindrical segment 193 can be 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm. Setting the diameter of the cylindrical segment 193 between 1 and 2 mm results in a smaller volume, which does not occupy the receiving cavity, while still achieving the functions of guidance and positioning. In addition, it has strong compressive strength, preventing the cylindrical segment 193 from breaking or deforming inward. Of course, the diameter of the cylindrical segment 193 can be appropriately increased or decreased according to the actual situation. For example, the diameter of the cylindrical segment 193 can also be between 0.5 mm and 1.0 mm, or between 2.0 mm and 5 mm.

[0100] The horizontal width d1 of the connecting segment 192 is between 1 and 2 mm, the horizontal thickness d2 is between 0.5 and 1.5 mm, and the vertical height h1 of the notch 191 is between 1 and 3 mm. For example, the horizontal width of the connecting segment 192 can be 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm, and the horizontal thickness can be 0.5 mm, 0.6 mm, 0.8 mm, 0.9 mm, 1 mm, 1.2 mm, 1.3 mm, 1.4 mm, and 1.5 mm. The vertical height of the notch 191 can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, and 3 mm, thereby improving the load-bearing capacity and compressive strength of the connecting segment 192.

[0101] The water purification device 1000 according to an embodiment of the present invention includes the housing assembly 100 of the above embodiment. Since the housing assembly 100 of the present invention has high structural strength and small size, the water purification device 1000 of the present invention has high structural strength and small size.

[0102] The following reference Figures 13-19 The housing assembly 100 is described in some other embodiments of the present invention.

[0103] like Figures 13 to 15 As shown, the housing assembly 100 includes a housing 10, which has a first sidewall 11 and a second sidewall 12 disposed opposite to each other. At least one of the first sidewall 11 and the second sidewall 12 is provided with a plurality of limiting protrusions extending vertically, and the plurality of limiting protrusions define a plurality of interconnected mounting cavities 13 within the housing 10.

[0104] It is understood that the housing assembly 100 of the present invention, by forming a plurality of vertically extending limiting protrusions inwardly on at least one of the first sidewall 11 and the second sidewall 12 of the outer shell 10, can enhance the structural strength of at least one of the first sidewall 11 and the second sidewall 12, thereby enhancing the structural strength of the outer shell 10. This provides better protection for the internal components installed within the outer shell 10, thereby reducing the risk of damage to the internal components during transportation and handling. Furthermore, the limiting protrusions define a plurality of interconnected mounting cavities 13 within the outer shell 10, which helps improve the installation stability of the internal components within the outer shell 10, thereby further enhancing the protective effect of the outer shell 10 on the internal components within the outer shell 10, and further reducing the risk of damage to the internal components within the outer shell 10 during transportation and handling.

[0105] Furthermore, such as Figures 16 to 17 As shown, the limiting protrusion smoothly transitions on the inner wall surface of the side wall.

[0106] It is understandable that by making the limiting protrusion smoothly transition on the inner wall surface of the side wall, the inner wall of the mounting cavity 13 defined by the limiting protrusion can be made to change more smoothly, thereby improving the noise reduction effect of the mounting cavity 13.

[0107] Furthermore, such as Figures 13 to 16 As shown, limiting protrusions are formed on both the first sidewall 11 and the second sidewall 12. Specifically, the limiting protrusions include a plurality of first limiting protrusions 111 formed on the first sidewall 11 and a plurality of second limiting protrusions 121 formed on the second sidewall 12, with the plurality of first limiting protrusions 111 and the plurality of second limiting protrusions 121 corresponding one-to-one. In this way, the structural strength of the outer shell 10 can be further improved.

[0108] Furthermore, such as Figure 15 As shown, the housing assembly 100 also has a third sidewall 14 and a fourth sidewall 15 disposed opposite to each other. The first sidewall 11, the third sidewall 14, the second sidewall 12 and the fourth sidewall 15 are connected end to end in sequence, and the connection points of the first sidewall 11, the third sidewall 14, the second sidewall 12 and the fourth sidewall 15 are smoothly connected.

[0109] In this way, the inner wall of the outer shell 10 can smoothly transition at the joints of the first side wall 11, the third side wall 14, the second side wall 12 and the fourth side wall 15, so that the cross-section of each mounting cavity 13 is approximately arc-shaped, thereby further improving the noise reduction effect of the mounting cavity 13.

[0110] Furthermore, such as Figure 15As shown, both the third sidewall 14 and the fourth sidewall 15 are plate-shaped, and the third sidewall 14 is set in a semi-circular arc shape; and / or, the fourth sidewall 15 is set in a semi-circular arc shape. In this way, the outer shell 10 has a structure that is narrow in the middle and wide at both ends, which not only simplifies the structure of the outer shell 10, but also further improves the noise reduction effect of the mounting cavity 13.

[0111] Furthermore, such as Figure 17 As shown, both the first sidewall 11 and the second sidewall 12 are plate-shaped, and the limiting protrusion is formed by a local inward bulge on the sidewall, making the cross-section of the outer shell 10 resemble a peanut shell. This simplifies the structure of the outer shell 10.

[0112] In optional embodiments, such as Figures 14 to 15 As shown, a first limiting protrusion 111 is provided on the first side wall 11, and a second limiting protrusion 121 is provided on the second side wall 12. The first limiting protrusion 111 and the second limiting protrusion 121 are arranged opposite to each other to define two mounting cavities 13 within the outer casing 10.

[0113] It is understood that the first sidewall 11 and the second sidewall may have at least one limiting protrusion, for example, as Figure 16 As shown, in some alternative embodiments of the housing 10 of the present invention, two first limiting protrusions 111 are provided on the first sidewall 11, and two second limiting protrusions 121 are provided on the second sidewall 12. The two first limiting protrusions 111 and the two second limiting protrusions 121 are arranged opposite to each other to define three mounting cavities 13 in the housing 10.

[0114] Of course, in other embodiments of the present invention, more mounting cavities 13 may be provided as needed.

[0115] Of course, the limiting protrusion can also be formed in other structural forms. It should be noted that the above-described method of forming the limiting protrusion is illustrative. The limiting protrusion can also be formed by the inner wall surfaces of the first sidewall 11 and the second sidewall 12 protruding inward, that is, the outer wall surfaces of the first sidewall 11 and the second sidewall do not have obvious concave surfaces.

[0116] like Figure 17 As shown, in some alternative embodiments of the housing 10 of the present invention, the limiting protrusion is formed by extending inwardly on the inner side of the side wall.

[0117] It should be particularly noted that the shell assembly 100 of the present invention has a peanut shell-shaped cross-section for the outer shell 10, which not only improves the structural strength of the outer shell 10, thereby improving the protective effect of the outer shell 10 on the internal components inside the outer shell 10, but also improves the noise reduction effect of the mounting cavity 13 inside the outer shell 10.

[0118] Furthermore, such as Figure 14 and Figure 18 As shown, the housing assembly 100 also includes a middle shell 20, which includes a connecting base shell 21 and a plurality of hollow support columns 22 protruding from the connecting base shell 21 and extending in the vertical direction. The middle shell 20 is installed inside the outer shell 10, and the periphery of the connecting base shell 211 is adapted to abut against the inner wall surface of the outer shell 10. Each hollow support column 22 is installed in a mounting cavity 13.

[0119] It is understood that the housing assembly 100 of the present invention can improve the overall structural strength of the housing assembly 100 by providing a middle shell 20 inside the outer shell 10; moreover, by adapting the periphery of the connecting base shell 21 to abut the inner wall surface of the outer shell 10, and by installing any hollow support column 22 in a mounting cavity 13 (the mounting cavity 13 has a limiting effect on the hollow support column 22), the assembly stability of the middle shell 20 inside the outer shell 10 can be improved.

[0120] Furthermore, such as Figure 15 and Figure 18 As shown, the connecting base shell 21 includes a base plate 211 and a surrounding plate 212 disposed around the base plate 211. The outer peripheral surface of the surrounding plate 212 is adapted to abut against the inner wall surface of the outer shell 10. The hollow support column 22 protrudes downward on the base plate 211. The base plate 211 is provided with a clearance through hole 2111 that communicates with the inner cavity of the hollow support column 22.

[0121] Thus, by protruding the hollow support column 22 downwards onto the substrate 211, the structure of the middle shell 20 can be simplified, making it easier to form. Moreover, by providing the surrounding plate 212, not only can the contact area between the upper end of the middle shell 20 and the inner wall of the outer shell 10 be increased, thereby enhancing the assembly stability of the middle shell 20, but the structural strength of the connecting substrate 211 can also be enhanced, thereby increasing the structural strength of the middle shell 20.

[0122] Of course, the connecting base shell 21 can also be located in the middle of the hollow support column 22.

[0123] Furthermore, such as Figure 19 As shown, a recess 2112 is provided in the middle of the substrate 211, and a hollow support column 22 is provided in the recess 2112. In this way, the structural strength of the substrate 211 can be enhanced, thereby enhancing the structural strength of the shell 20. In addition, by providing the recess 2112 in the middle of the substrate 211, installation space can also be provided for the water circuit components of the water purification device 1000.

[0124] It is understandable that the projection of the connecting substrate 211 on the horizontal plane is consistent with the projection of the outer shell 10, both being peanut-shell shaped, in order to facilitate the installation of the middle shell 20.

[0125] Specifically, such as Figure 13As shown, the housing 10 has an upper opening, and the housing assembly 100 also includes an upper cover 30 that covers the upper opening of the housing 10. The housing 10 also has a lower opening, and the housing assembly 100 also includes a base 40 that covers the lower opening of the housing 10.

[0126] In this embodiment, the outer shell 10 is integrally injection molded, thereby further improving the structural strength of the outer shell 10.

[0127] The water purification device 1000 according to an embodiment of the present invention includes the housing assembly 100 of the above embodiment. Since the housing assembly 100 of the present invention has high structural strength and small size, the water purification device 1000 of the present invention has high structural strength and small size.

[0128] In one specific embodiment of the present invention, such as Figure 13 and Figure 15 As shown, the housing assembly 100 for the water purification device 1000 includes a housing 10, the housing 10 having a first sidewall 11 and a second sidewall 12 disposed opposite to each other, at least one of the first sidewall 11 and the second sidewall 12 being inwardly protruding to form a plurality of limiting protrusions extending vertically, the plurality of limiting protrusions defining a plurality of interconnected mounting cavities 13 within the housing 10.

[0129] Optionally, such as Figures 16 to 17 As shown, the limiting protrusion smoothly transitions on the inner wall surface of the side wall.

[0130] Optionally, such as Figures 13 to 16 As shown, the limiting protrusion includes a plurality of first limiting protrusions 111 formed on the first sidewall 11 and a plurality of second limiting protrusions 121 formed on the second sidewall 12, with the plurality of first limiting protrusions 111 and the plurality of second limiting protrusions 121 being arranged in a one-to-one correspondence.

[0131] Optionally, such as Figure 17 As shown, the limiting protrusion is formed by a local inward bulge on the side wall, making the cross-section of the outer shell 10 resemble a peanut shell.

[0132] Optionally, such as Figure 15 As shown, the housing assembly 100 also has a third sidewall 14 and a fourth sidewall 15 disposed opposite to each other. The first sidewall 11, the third sidewall 14, the second sidewall 12 and the fourth sidewall 15 are connected end to end in sequence, and the connection points of the first sidewall 11, the third sidewall 14, the second sidewall 12 and the fourth sidewall 15 are smoothly connected.

[0133] Optionally, the third sidewall 14 is configured as a semi-circular arc; and / or, the fourth sidewall 15 is configured as a semi-circular arc.

[0134] Optionally, the housing assembly 100 further includes a middle shell 20, which includes a connecting base shell 21 and a plurality of hollow support columns 22 protruding from the connecting base shell 21 and extending in the vertical direction. The middle shell 20 is installed inside the outer shell 10, and the periphery of the connecting base shell 21 is adapted to abut against the inner wall surface of the outer shell 10. Each of the hollow support columns 22 is installed in a mounting cavity 13.

[0135] Optionally, such as Figure 14 and Figure 18 As shown, the connecting base shell 21 includes a base plate 211 and a surrounding plate 212 disposed around the base plate 211. The outer peripheral surface of the surrounding plate 212 is adapted to abut against the inner wall surface of the outer shell 10. The hollow support column 22 protrudes downward on the base plate 211. The base plate 211 is provided with a clearance through hole 2111 communicating with the inner cavity of the hollow support column 22.

[0136] Optionally, such as Figure 19 As shown, the substrate 211 has a recess 2112 in the middle, and the hollow support column 22 is disposed in the recess 2112.

[0137] The present invention includes the water purification device 1000 of the above embodiments, including a housing assembly 100. The housing assembly 100 includes a shell 10, the shell 10 having a first sidewall 11 and a second sidewall 12 disposed opposite to each other, at least one of the first sidewall 11 and the second sidewall 12 having a plurality of limiting protrusions extending vertically, the plurality of limiting protrusions defining a plurality of interconnected mounting cavities 13 within the shell 10.

[0138] Optionally, the water purification device 1000 further includes a plurality of filter elements 200, and the housing assembly 100 further includes a middle shell 20. The middle shell 20 includes a connecting base shell 21 and a plurality of hollow support columns 22 protruding from the connecting base shell 21 and extending in the vertical direction. The middle shell 20 is installed inside the outer shell 10, and the periphery of the connecting base shell 21 is adapted to abut against the inner wall surface of the outer shell 10. The plurality of filter elements 200 are installed one-to-one in the plurality of hollow support columns 22, and the plurality of hollow support columns 22 are installed one-to-one in the plurality of mounting cavities 13.

[0139] Optionally, the water purification device 1000 further includes a water pump assembly 300, which is installed inside the housing 10 and located below the middle housing 20.

[0140] Optionally, the water purification device 1000 further includes a water pump assembly 300 and a plurality of filter elements 200. The housing assembly 100 further includes a middle shell 20, which includes a connecting base shell 21 and a plurality of hollow support columns 22 protruding from the connecting base shell 21 and extending in the vertical direction. The middle shell 20 is installed inside the outer shell 10, and the periphery of the connecting base shell 21 is adapted to abut against the inner wall surface of the outer shell 10. The plurality of filter elements 200 are installed one-to-one in the plurality of hollow support columns 22. The water pump assembly 300 is installed in one of the mounting cavities 13, and the plurality of hollow support columns 22 are installed one-to-one in the remaining mounting cavities 13. Alternatively, the water pump assembly 300 is installed in one of the hollow support columns 22, and the plurality of filter elements 200 are installed one-to-one in the remaining hollow support columns 22, and the hollow support columns 22 are installed one-to-one in the plurality of mounting cavities 13.

[0141] The following reference Figures 13-34 The housing assembly 100 is described in some other embodiments of the present invention.

[0142] In one embodiment of the present invention, such as Figure 20 Combination Figures 21-24 As shown, the water purification device 1000 includes a housing assembly 100 and a display assembly 500. The display assembly 500 includes a display panel 501 and control keys 502 mounted on the display panel 501. The housing assembly 100 includes a shell 10, which includes a shell body and a display and control section corresponding to the display assembly 500. The display and control section is integrally formed with the shell body, and the display assembly 500 is mounted on the inner wall of the display and control section.

[0143] It is understood that the water purification device 1000 of the present invention improves the structural integrity of the outer shell 10 by installing the display component 500 on the inner wall of the display and control unit and integrally molding the display and control unit with the shell body, thereby improving the structural strength of the outer shell 10 and better protecting the internal components installed in the outer shell 10, thereby reducing the risk of damage to the internal components in the outer shell 10 during transportation and handling.

[0144] Furthermore, the control key 502 is configured as a touch key, which is attached to the inner wall surface of the display control unit.

[0145] It is understandable that by setting the control key 502 as a touch key, when the display component 500 is inserted into the housing 10 along with the filter element 200 and other components, the control key 502 can be retracted inward, thereby avoiding interference between the control key 502 and the side wall of the housing 10. This allows the display component 500 to be installed inside the housing 10 without opening an insertion port on the side wall of the housing 10.

[0146] Of course, the display component 500 can also be installed without a mounting port through other structural forms. For example, in another embodiment of the present invention, the control key 502 is set as a telescopic key, and the display control unit has a key through hole, through which the telescopic key is movably inserted. In this embodiment, such as Figure 23 As shown, when the display component 500 is inserted into the housing 10 along with components such as the filter element 200, the control key 502 can also be retracted inward to avoid interference between the control key 502 and the side wall of the housing 10. In this embodiment, the retractable design of the control key 502 can be achieved by elastic elements such as compression springs and elastic pressure plates.

[0147] Furthermore, such as Figure 21 Combination Figure 22 , Figure 23 Combination Figure 24 As shown, the display panel 501 is provided with an indicator lamp 503, and the display control unit is formed with a thin-walled transparent diffuser 16. The wall thickness of the thin-walled transparent diffuser 16 is reduced, and the indicator lamp 503 is provided corresponding to the thin-walled transparent diffuser 16.

[0148] It is understandable that by reducing the wall thickness of the thin-walled transparent diffuser 16, the light emitted by the indicator lamp 503 can be diffused from the thin-walled transparent diffuser 16 and thus received by the user.

[0149] Of course, other structural forms can also be used to allow the light emitted by the display lamp 503 to pass through the housing 10 and diffuse. For example, in other embodiments of the present invention, the display control unit is provided with a light-diffusing hole (not shown), and the display lamp 503 is provided corresponding to the light-diffusing hole, which can diffuse the light emitted by the display lamp 503.

[0150] Further, refer to Figure 24 As shown, the display component 500 also includes a protective plate 504, which is mounted on the display plate 501. A protective post 505 is provided on the protective plate 504 corresponding to the display lamp 503. A focusing hole 506 is provided on the protective post 505, and the display lamp 503 is installed in the focusing hole 506. The focusing hole 506 is provided in relation to the diffuser hole. A guide hole 507 is provided on the protective plate 504 corresponding to the control key 502.

[0151] Thus, the protective plate 504 can protect the indicator light 503 and the control key 502. Moreover, by setting a protective post 505 on the protective plate 504 and opening a focusing hole 506 on the protective post 505, the light emitted by the indicator light 503 can be focused and emitted along the extension direction of the focusing hole 506.

[0152] Specifically, such as Figure 22 Combination Figure 23 As shown, the protective plate 504 also has a guide post 508 corresponding to the control key 502. A guide hole 507 is formed on the guide post 508, and the control key 502 is partially disposed within the guide hole 507, allowing it to extend and retract within the guide hole 507. Thus, by providing the guide hole 507, the extension and retraction direction of the control key 502 can be restricted, thereby facilitating the assembly of the display component 500.

[0153] Furthermore, such as Figure 22 and Figure 25 As shown, the housing assembly 100 also includes a middle housing 20, the filter element 200 of the water purification device 1000 is mounted on the middle housing 20, the display assembly 500 is mounted on the outer side of the middle housing 20, and the middle housing 20 is mounted inside the outer housing 10.

[0154] Thus, by setting the middle shell 20, the overall structural strength of the shell assembly 100 can be improved, thereby enhancing the protection of the filter element 200 of the water purification equipment 1000. Of course, the middle shell 20 can also be omitted, in which case the display assembly 500 can be directly installed on the filter element 200.

[0155] Furthermore, such as Figure 14 and Figure 19 As shown, in order to enhance the protection of the display panel 501 and components such as the display lamp 503 and control key 502 provided on the display panel 501, the display assembly 500 also includes a display box 509, the display panel 501 is installed in the display box 509, and the display box 509 is installed on the middle shell 20.

[0156] In this embodiment, preferably, the display box 509 is integrally formed on the outer side of the middle shell 20. This not only reduces the installation process of mounting the display box 509 onto the middle shell 20, thereby improving assembly efficiency, but also enhances the structural strength of the middle shell 20.

[0157] Furthermore, such as Figures 13-15 , Figure 20 and Figure 26 As shown, the outer shell 10 is configured as a hollow structure with openings at both ends. The shell assembly 100 also includes a top cover 30 and / or a base 40; the top cover 30 covers the upper opening of the outer shell 10, and / or the base 40 covers the lower opening of the outer shell 10. Thus, by configuring the outer shell 10 as a hollow structure with openings at both ends, it is convenient to integrally injection mold the outer shell 10.

[0158] Furthermore, the upper end of the middle shell 20 is connected to the upper end of the inner wall surface of the outer shell 10 via a snap-fit ​​structure. This allows for easy assembly and disassembly of the middle shell 20 and the outer shell 10.

[0159] Specifically, such as Figure 22 and Figure 28 As shown, the middle shell 20 includes a connecting base shell 21 and a plurality of hollow support columns 22 protruding from the connecting base shell 21 and extending in the vertical direction. The periphery of the connecting base shell 21 is adapted to abut against the inner wall surface of the outer shell 10, and the display component 500 is mounted on the outer side of a hollow support column 22.

[0160] like Figure 26 Combination Figure 27 , Figure 28 Combination Figure 29 The inner wall surface of the outer shell 10 is formed with a limiting groove 17, and the connecting base shell 21 is provided with a limiting protrusion 2113 protruding downward, the limiting protrusion 2113 being adapted to snap into the limiting groove 17. The snap-fit ​​structure includes the limiting groove 17 and the limiting protrusion 2113.

[0161] This simplifies the snap-fit ​​structure, making it easier to assemble and disassemble the middle shell 20 and the outer shell 10.

[0162] In this embodiment, as Figure 19 As shown, the connecting base shell 21 includes a base plate 211 and a surrounding plate 212 disposed around the base plate 211. The outer peripheral surface of the surrounding plate 212 is adapted to abut against the inner wall surface of the outer shell 10. The hollow support column 22 protrudes downward on the base plate 211. The base plate 211 has a clearance through hole 2111 communicating with the inner cavity of the hollow support column 22. The limiting protrusion 2113 is formed by protruding downward from the lower side edge of the base plate 211.

[0163] In this embodiment, as Figure 26 Combination Figure 27 As shown, the limiting groove 17 is formed by a semi-annular protrusion on the inner wall surface of the outer shell 10, which surrounds the inner wall surface of the outer shell 10.

[0164] This facilitates the insertion of the limiting card protrusion 2113 and the limiting card slot 17, thereby making it easy to disassemble and assemble the middle shell 20 and the outer shell 10.

[0165] In this embodiment, as Figure 19 As shown, a recess 2112 is provided in the middle of the substrate 211, and the hollow support column 22 is disposed in the recess 2112. This enhances the structural strength of the substrate 211, thereby enhancing the structural strength of the inner shell 20. Furthermore, by providing the recess 2112 in the middle of the substrate 211, installation space can be provided for the water circuit components of the water purification device 1000.

[0166] Furthermore, such as Figure 14 , Figures 30-32 As shown, the water purification device 1000 also includes a main control board 600, which is electrically connected to the display board 501; the water purification device 1000 also includes a TDS detection unit 601, which is integrated on the main control board 600. Thus, by integrating the TDS detection unit 601 onto the main control board 600, the overall structure of the water purification device 1000 can be simplified; moreover, the assembly process of the water purification device 1000 can also be simplified.

[0167] Furthermore, such as Figures 16-17 As shown, the cross-section of the outer shell 10 is elliptical, or the cross-section of the outer shell 10 is peanut-shell shaped, or the cross-section of the outer shell 10 is waist-shaped.

[0168] In this embodiment, in order to improve the structural strength of the outer shell 10 and the noise reduction effect of the outer shell 10, the cross-section of the outer shell 10 is shaped like a peanut shell.

[0169] Without loss of generality, such as Figure 14 As shown, the water purification equipment 1000 also includes a filter element 200, a water pump assembly 300, a water circuit assembly, etc.; the filter element 200 is installed inside the hollow support column 22; the water circuit assembly includes a water circuit plate 401 and water circuit pipes, etc.; the water pump assembly 300 includes a water pump housing 302 and a water pump 301 installed inside the water pump housing 302.

[0170] The water purification device 1000 according to an embodiment of the present invention includes the housing assembly 100 of the above embodiment. Since the housing assembly 100 of the present invention has high structural strength and small size, the water purification device 1000 of the present invention has high structural strength and small size.

[0171] In a specific embodiment of the water purification device 1000 of the present invention, such as Figure 20 Combination Figures 21-24 As shown, the water purification device 1000 includes a housing assembly 100 and a display assembly 500. The display assembly 500 includes a display panel 501 and control keys 502 mounted on the display panel 501. The housing assembly 100 includes a shell 10, which includes a shell body and a display and control section corresponding to the display assembly 500. The display and control section is integrally formed with the shell body, and the display assembly 500 is mounted on the inner wall surface of the display and control section.

[0173] Optionally, the housing assembly 100 further includes a middle housing 20, on which the filter element 200 of the water purification device 1000 is mounted, and the display assembly 500 is mounted on the outer side of the middle housing 20.

[0174] Optionally, the display assembly 500 further includes a display box 509, the display panel 501 is installed inside the display box 509, and the display box 509 is installed on the middle shell 20.

[0175] Optionally, the display box 509 is integrally formed on the outer side of the middle shell 20.

[0176] Optionally, such as Figure 21 Combination Figure 22 , Figure 23 Combination Figure 24 As shown, the display panel 501 is provided with an indicator lamp 503, and the display control unit is formed with a thin-walled transparent diffuser 16. The wall thickness of the thin-walled transparent diffuser 16 is reduced, and the indicator lamp 503 is provided corresponding to the thin-walled transparent diffuser 16; or, the display control unit is provided with a diffuser hole, and the indicator lamp 503 is provided corresponding to the diffuser hole.

[0177] Optionally, refer to Figure 24 As shown, the display assembly 500 further includes a protective plate 504, which is mounted on the display panel 501. A protective post 505 is provided on the protective plate 504 corresponding to the display lamp 503. A focusing hole 506 is provided on the protective post 505, and the display lamp 503 is installed in the focusing hole 506. The focusing hole 506 is provided corresponding to the diffuser hole. A guide hole 507 is provided on the protective plate 504 corresponding to the control key 502.

[0178] Optionally, the outer shell 10 is configured as a hollow structure with openings at both ends, and the shell assembly 100 further includes an upper cover 30 and / or a base 40; the upper cover 30 covers the upper opening of the outer shell 10, and / or the base 40 covers the lower opening of the outer shell 10.

[0179] Optionally, the upper end of the middle shell 20 is connected to the upper end of the inner wall surface of the outer shell 10 by a snap-fit ​​structure.

[0180] Optionally, the middle shell 20 includes a connecting base shell 21 and a plurality of hollow support columns 22 protruding from the connecting base shell 21 and extending in the vertical direction, wherein the periphery of the connecting base shell 21 is adapted to abut against the inner wall surface of the outer shell 10.

[0181] The inner wall surface of the outer shell 10 is formed with a limiting groove 17, and the connecting base shell 21 is provided with a limiting protrusion 2113 protruding downward, the limiting protrusion 2113 being adapted to be engaged in the limiting groove 17.

[0182] Optionally, the water purification device 1000 further includes a main control board 600, which is electrically connected to the display board 501;

[0183] The water purification equipment 1000 also includes a TDS detection unit 601, which is integrated on the main control board 600.

[0184] Optionally, the cross-section of the outer shell 10 is elliptical, or the cross-section of the outer shell 10 is peanut-shell shaped, or the cross-section of the outer shell 10 is waist-shaped.

[0185] The following reference Figures 13-41 The housing assembly 100 is described in some other embodiments of the present invention.

[0186] like Figure 19 As shown, the housing assembly 100 includes a middle shell 20, the middle shell 20 includes a connecting base shell 21 and at least two hollow support columns 22 protruding from the connecting base shell 21 and extending downward. The inner cavity of the hollow support column 22 is a filter element cavity 221 for installing the filter element 200 of the water purification equipment 1000, and a structural reinforcement 50 is provided between the two hollow support columns 22, the structural reinforcement 50 connecting the two hollow support columns 22.

[0187] It is understood that the housing assembly 100 of the present invention, by providing at least two hollow support columns 22 protruding on the connecting base shell 21 and providing structural reinforcement members 50 to connect the two hollow support columns 22, can increase the constraint on the hollow support columns 22, thereby improving the overall structural strength of the middle shell 20, thereby reducing the risk of damage to the middle shell 20 and filter element 200 during transportation and handling.

[0188] For the sake of simplicity, the present invention is explained using an example of two hollow support columns 22. However, it should be noted that the number of hollow support columns 22 may also be more than two. When there are more than two, structural reinforcement members 50 may also be provided between other adjacent hollow support columns 22 to further improve the overall structural strength of the shell 20.

[0189] Furthermore, such as Figure 19As shown, the structural reinforcement 50 includes a first reinforcing plate 51, a second reinforcing plate 52, and a third reinforcing plate 53 connected in sequence. The first reinforcing plate 51 and the third reinforcing plate 53 are both located on the same side of the second reinforcing plate 52. The free end of the first reinforcing plate 51 is connected to a hollow support column 22, and the free end of the third reinforcing plate 53 is connected to another hollow support column 22. This simplifies the structure of the structural reinforcement 50 and facilitates its molding.

[0190] Furthermore, such as Figure 19 As shown, the second reinforcing plate 52 is offset from the common axial section of the two hollow support columns 22.

[0191] Specifically, the two hollow support columns 22 are spaced apart to form a water passage gap 23 between them, which is used for the water pipe of the water purification device 1000 to pass through. It can be understood that by offsetting the second reinforcing plate 52 from the common axial section of the two hollow support columns 22, the structural reinforcement 50 can avoid the water passage gap 23 in the shell assembly 100 of the present invention, thus making the structural design of the shell 20 compact and reasonable.

[0192] Furthermore, such as Figure 19 As shown, the side of the first reinforcing plate 51 opposite to the third reinforcing plate 53 is provided with a first reinforcing rib 54 connecting the first reinforcing plate 51 and the hollow support column 22 connected thereto; and / or, the side of the third reinforcing plate 53 opposite to the first reinforcing plate 51 is provided with a second reinforcing rib 55 connecting the third reinforcing plate 53 and the hollow support column 22 connected thereto.

[0193] Thus, by setting reinforcing ribs to connect the corresponding reinforcing plates and the hollow support columns 22, the structural strength between the structural reinforcing member 50 and the hollow support columns 22 can be improved, thereby further improving the overall structural strength of the inner shell 20.

[0194] In this embodiment, preferably, as follows: Figure 19 As shown, the first reinforcing plate 51 has a first reinforcing rib 54 on its side, and the third reinforcing plate 53 has a second reinforcing rib 55 on its side.

[0195] Furthermore, such as Figures 18 to 19 As shown, the connecting base shell 21 includes a base plate 211 and a surrounding plate 212 disposed around the periphery of the base plate 211. The hollow support column 22 protrudes downward onto the base plate 211, and the base plate 211 has a clearance through hole 2111 communicating with the inner cavity of the hollow support column 22. Thus, by providing the surrounding plate 212, the structural strength of the connecting base plate 211 can be enhanced, thereby enhancing the structural strength of the middle shell 20.

[0196] Furthermore, such as Figure 19 As shown, a recess 2112 is provided in the middle of the substrate 211, and the hollow support column 22 is disposed in the recess 2112. This enhances the structural strength of the substrate 211, thereby enhancing the structural strength of the inner shell 20. Furthermore, by providing the recess 2112 in the middle of the substrate 211, installation space can be provided for the water circuit components of the water purification device 1000.

[0197] Furthermore, the structural reinforcement 50 is integrally formed on the outer surface of the hollow support column 22. This not only reduces the assembly process of the structural reinforcement 50, but also further enhances the structural strength of the inner shell 20.

[0198] Furthermore, such as Figures 1 to 5 As shown, one of the hollow support columns 22 has an electrical control installation area on its outer side for installing electrical control components of the water purification equipment 1000, and a baffle plate 60 is provided on the upper side of the electrical control installation area.

[0199] Thus, by installing a baffle plate 60 above the electrical control installation area, water can be effectively dripped and flowed towards the electrical control installation area, thereby improving the safety of the water purification equipment 1000 in operation.

[0200] Specifically, such as Figure 31 Combination Figure 32 As shown, the upper surface of the baffle plate 60 is a conical surface that is higher in the middle and lower around the edges. This facilitates the diversion of water away from the electrical control installation area.

[0201] Of course, the upper surface of the baffle plate 60 can also be configured with other structural forms, as long as it facilitates water flow and does not flow into the electrical control installation area.

[0202] Furthermore, such as Figure 31 Combination Figure 32 As shown, the baffle plate 60 has a first side and a second side that are adjacent to the hollow support column 22 and arranged opposite to each other. The first side and / or the second side of the baffle plate are provided with downwardly extending side guide plates 61. In this way, water flow can be further prevented from entering the electrical control installation area.

[0203] Specifically, such as Figure 31 Combination Figure 32 As shown, the electrical control installation area is provided with an electrical control box 602 integrally formed with the hollow support column 22. The electrical control box 602 is used to install the main control board 601 of the water purification equipment 1000.

[0204] Specifically, such as Figure 31 Combination Figure 32As shown, the electrical control installation area is provided with a WiFi installation box 701 integrally formed with the hollow support column 22. The WiFi installation box 701 is used to install the WiFi unit 700 of the water purification equipment 1000.

[0205] Specifically, such as Figure 31 Combination Figure 32 As shown, the electrical control box 602 is located below the WiFi installation box 701. Of course, the electrical control box 602 can also be located above or to the side of the WiFi installation box 701.

[0206] In other embodiments of the present invention, only one of the electrical control box 602 and the WiFi installation box 701 may be provided in the electrical control installation area.

[0207] Furthermore, such as Figure 18 Combination Figure 22 As shown, the housing assembly 100 also includes an outer shell 10, with the middle shell 20 installed inside the outer shell 10, and the periphery of the connecting base shell 21 adapted to abut against the inner wall surface of the outer shell 10. Thus, by providing the outer shell 10, not only can the middle shell 20 and the filter element 200 installed inside the middle shell 20 be protected, but the overall structural strength of the housing assembly 100 can also be improved.

[0208] Specifically, the outer peripheral surface of the enclosure 212 is adapted to abut against the inner wall surface of the outer shell 10. It can be understood that by providing the enclosure 212, the contact area between the upper end of the middle shell 20 and the inner wall surface of the outer shell 10 can be increased, thereby enhancing the assembly stability of the middle shell 20 within the outer shell 10.

[0209] Furthermore, such as Figures 15 to 17 As shown, the outer shell 10 has a first sidewall 11 and a second sidewall 12 disposed opposite to each other. At least one of the first sidewall 11 and the second sidewall 12 is provided with a plurality of limiting protrusions extending vertically. The plurality of limiting protrusions define a plurality of interconnected mounting cavities 13 within the outer shell 10. Each of the hollow support columns 22 is installed in a mounting cavity 13.

[0210] Thus, by defining multiple mounting cavities 13 within the outer casing 10 to mount the hollow support column 22, the constraint on the hollow support column 22 can be enhanced, thereby improving the assembly stability of the middle shell 20 within the outer casing 10. Furthermore, by inwardly protruding at least one of the first sidewall 11 and the second sidewall 12 of the outer casing 10 to form a plurality of vertically extending limiting protrusions, the structural strength of at least one of the first sidewall 11 and the second sidewall 12 can be enhanced, thereby increasing the structural strength of the outer casing 10. This provides better protection for internal components (such as the middle shell 20, filter element 200, etc.) installed within the outer casing 10, thereby reducing the risk of damage to the internal components during transportation and handling.

[0211] Furthermore, such as Figures 15 to 17 As shown, the limiting protrusion smoothly transitions on the inner wall surface of the side wall.

[0212] It is understandable that by making the limiting protrusion smoothly transition on the inner wall surface of the side wall, the inner wall of the mounting cavity 13 defined by the limiting protrusion can be made to change more smoothly, thereby improving the noise reduction effect of the mounting cavity 13.

[0213] Furthermore, such as Figures 15 to 17 As shown, limiting protrusions are formed on both the first sidewall 11 and the second sidewall 12. Specifically, the limiting protrusions include a plurality of first limiting protrusions 111 formed on the first sidewall 11 and a plurality of second limiting protrusions 121 formed on the second sidewall 12, with the plurality of first limiting protrusions 111 and the plurality of second limiting protrusions 121 corresponding one-to-one. In this way, the structural strength of the outer shell 10 can be further improved.

[0214] Furthermore, such as Figures 15 to 17 As shown, the housing assembly 100 also has a third sidewall 14 and a fourth sidewall 1515 disposed opposite to each other. The first sidewall 11, the third sidewall 14, the second sidewall 12 and the fourth sidewall 15 are connected end to end in sequence, and the connection points of the first sidewall 11, the third sidewall 14, the second sidewall 12 and the fourth sidewall 15 are smoothly connected.

[0215] In this way, the inner wall of the outer shell 10 can smoothly transition at the joints of the first side wall 11, the third side wall 14, the second side wall 12 and the fourth side wall 15, so that the cross-section of each mounting cavity 13 is approximately circular, thereby further improving the noise reduction effect of the mounting cavity 13.

[0216] Furthermore, such as Figures 15 to 17As shown, both the third sidewall 14 and the fourth sidewall 15 are plate-shaped, and the third sidewall 14 is set in a semi-circular arc shape; and / or, the fourth sidewall 15 is set in a semi-circular arc shape. This not only simplifies the structure of the outer casing 10, but also further improves the noise reduction effect of the mounting cavity 13.

[0217] Furthermore, such as Figures 15 to 17 As shown, both the first sidewall 11 and the second sidewall 12 are plate-shaped, and the limiting protrusion 121 is formed by a local inward bulge on the sidewall, making the cross-section of the outer shell 10 resemble a peanut shell. This simplifies the structure of the outer shell 10.

[0218] In this embodiment, as Figures 15 to 17 As shown, a first limiting protrusion 111 is provided on the first sidewall 11, and a second limiting protrusion 121 is provided on the second sidewall 12. The first limiting protrusion 111 and the second limiting protrusion 121 are arranged opposite to each other to define two mounting cavities 13 within the outer casing 10.

[0219] Specifically, such as Figure 13 As shown, the outer casing 10 has an upper opening, and the casing assembly 100 further includes an upper cover 30 that covers the upper opening of the outer casing 10. The outer casing 10 also has a lower opening, and the casing assembly 100 further includes a base 40 that covers the lower opening of the outer casing 10.

[0220] In this embodiment, the outer shell 10 is integrally injection molded.

[0221] This invention also proposes a water purification device 1000. For example... Figures 13 to 28 As shown, the water purification device 1000 includes the housing assembly 100 as described above. The specific structure of the housing assembly 100 is as described in the above embodiments. Since the water purification device 1000 of the present invention adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0222] Specifically, such as Figure 28 As shown, the water purification device 1000 includes a plurality of filter elements 200, which are installed in the filter element cavity 221 of the hollow support column 22.

[0223] Furthermore, such as Figure 14 Combination Figure 25 As shown, the water inlet device also includes a water pump assembly 300, which is installed inside the outer casing 10 and located below the middle casing 20.

[0224] Specifically, such as Figures 11 to 13As shown, the water pump assembly 300 includes a water pump housing 302 and a water pump 301 installed in the water pump housing 302. The water pump 301 is placed horizontally so that the space inside the housing 10 is arranged compactly, which is conducive to realizing the miniaturization design of the water purification equipment 1000.

[0225] Specifically, such as Figures 11 to 13 As shown, the water purification equipment 1000 includes an electrical control component, which includes a main control board 600, which is installed inside an electrical control box 602.

[0226] Specifically, such as Figure 31 Combined with the diagram Figure 32 As shown, the electronic control component also includes a WiFi unit 700, which is installed inside the WiFi mounting box 701.

[0227] Without loss of generality, such as Figure 22 and Figure 25 As shown, the water purification equipment 1000 also includes water circuit components, which include a water circuit board 401 and water circuit pipes.

[0228] In one specific embodiment of the present invention, such as Figure 18 and Figure 19 As shown, the housing assembly 100 for the water purification device 1000 includes a middle shell 20. The middle shell 20 includes a connecting base shell 21 and at least two hollow support columns 22 protruding from the connecting base shell 21 and extending downward. The inner cavity of the hollow support column 22 is a filter element 200 cavity for installing the filter element 200 of the water purification device 1000, and a structural reinforcement member 50 is provided between the two hollow support columns 22.

[0229] Optionally, such as Figure 19 As shown, the structural reinforcement 50 includes a first reinforcement plate 51, a second reinforcement plate 52, and a third reinforcement plate 53 connected in sequence. The first reinforcement plate 51 and the third reinforcement plate 53 are both located on the same side of the second reinforcement plate 52. The free end of the first reinforcement plate 51 is connected to a hollow support column 22, and the free end of the third reinforcement plate 53 is connected to another hollow support column 22.

[0230] Optionally, the second reinforcing plate 52 is offset from the common axial section of the two hollow support columns 22.

[0231] Optionally, the side of the first reinforcing plate 51 opposite to the third reinforcing plate 53 is provided with a first reinforcing rib 54 connecting the first reinforcing plate 51 and the hollow support column 22 connected thereto; and / or, the side of the third reinforcing plate 53 opposite to the first reinforcing plate 51 is provided with a second reinforcing rib 55 connecting the third reinforcing plate 53 and the hollow support column 22 connected thereto.

[0232] Optionally, one of the hollow support columns 22 has an electrical control mounting area on its outer side for mounting the electrical control components of the water purification equipment 1000, and a baffle plate 60 is provided on the upper side of the electrical control mounting area.

[0233] Optionally, the upper surface of the baffle plate 60 is a conical surface that is higher in the middle and lower around the edges.

[0234] Optionally, the baffle plate 60 has a first side and a second side that are adjacent to the hollow support column 22 and are arranged opposite to each other, and the first side and / or the second side of the baffle plate 60 are provided with a downwardly extending side guide plate 61.

[0235] Optionally, the housing assembly 100 further includes an outer shell 10, the middle shell 20 is installed inside the outer shell 10, and the periphery of the connecting base shell 21 is adapted to abut against the inner wall surface of the outer shell 10.

[0236] Optionally, the outer casing 10 has a first sidewall 11 and a second sidewall 12 disposed opposite to each other, at least one of the first sidewall 11 and the second sidewall 12 is provided with a plurality of limiting protrusions extending vertically, and the plurality of limiting protrusions define a plurality of interconnected mounting cavities 13 within the outer casing 10; any of the hollow support columns 22 is installed in one of the mounting cavities 13.

[0237] The present invention includes the water purification device 1000 of the above embodiments, including a housing assembly 100. The housing assembly 100 includes a middle shell 20, the middle shell 20 including a connecting base shell 21 and at least two hollow support columns 22 protruding from the connecting base shell 21 and extending downward. The inner cavity of the hollow support column 22 is a filter element 200 cavity for installing the filter element 200 of the water purification device 1000, and a structural reinforcement member 50 is provided between the two hollow support columns 22.

[0238] The following reference Figures 13-41 The housing assembly 100 is described in some other embodiments of the present invention.

[0239] In embodiments of the present invention, such as Figure 33 , Figure 34 and Figure 40As shown, the housing assembly 100 includes an outer shell 10 and an upper cover 30. The outer shell 10 has an upper opening, and the upper cover 30 covers the upper opening of the outer shell 10. The edge of the upper cover 30 is provided with a lifting flange 31.

[0240] The housing assembly 100 of the present invention, by providing a lifting flange 31 on the edge of the upper cover 30, makes it convenient for the user to grasp the upper cover 30 with their hand (i.e., the upper cover 30 is easy to grasp by grasping the lifting flange 31), making it easy for the user to open the upper cover 30; at the same time, without the need for auxiliary tools, the upper cover 30 and the outer shell 10 are not easily damaged, and the whole structure is simple and reasonable.

[0241] Furthermore, such as Figure 33 As shown, the lifting flange 31 protrudes from the outer surface of the housing 10. This further facilitates the user's gripping.

[0242] Furthermore, such as Figure 34 Combination Figure 35 , Figure 36 Combination Figure 37 As shown, the lifting flange 31 includes a connecting portion 311 protruding from the upper surface of the cover 30, and a gripping portion 312 extending outward from the connecting portion 311. The gripping portion 312 protrudes from the outer side of the outer shell 10. This makes the structure of the lifting flange 31 simple and easy to manufacture.

[0243] Specifically, such as Figure 34 Combination Figure 35 , Figure 36 Combination Figure 37 As shown, the gripping part 312 is plate-shaped to facilitate user gripping. Of course, the gripping part 312 can also be configured in other shapes that are easy for users to grip, such as a pull ring or a block, etc., and the present invention is not limited thereto.

[0244] Furthermore, such as Figure 36 Combination Figure 37 As shown, a thinning notch 313 is provided on the lower surface of the upper cover 30 at the connection portion 311.

[0245] It is understood that the upper cover 30 is typically integrally injection molded. In the housing assembly 100 of the present invention, by opening a thinning notch 313 at the connecting portion 311 on the lower surface of the upper cover 30, the thickness variation of the upper cover 30 at the lifting flange 312 can be more uniform, thereby facilitating the injection molding of the upper cover 30.

[0246] It should be noted that in other embodiments of the present invention, the lifting flange 31 may also be configured as a pull ring or even a handle, as long as it is convenient for the user to grip. Of course, in actual production, factors such as aesthetics, convenience, and processing difficulty must also be considered, and those skilled in the art can make their own choices according to the actual situation.

[0247] Furthermore, such as Figure 15 , Figure 20 and Figure 41 As shown, the upper surface of the outer casing 10 is provided with an annular recessed groove 18, and the periphery of the upper cover 30 is adapted to be accommodated in the annular recessed groove 18 so that the upper cover 30 covers the upper opening of the outer casing 10; during assembly, it is only necessary to install the periphery of the upper cover 30 into the annular recessed groove 18. In this way, the assembly between the upper cover 30 and the outer casing 10 is simple and convenient.

[0248] Furthermore, the periphery of the upper cover 30 is interference-fitted with the annular recessed groove 18. This improves the connection stability between the upper cover 30 and the outer shell 10, making the connection between the upper cover 30 and the outer shell 10 more secure.

[0249] Of course, in order to improve the connection stability between the top cover 30 and the outer shell 10, a snap-fit ​​structure or a screw locking structure can also be used to connect the top cover 30 and the outer shell 10.

[0250] Specifically, the cross-section of the outer shell 10 is elliptical; or, the cross-section of the outer shell 10 is peanut-shell shaped; or, the cross-section of the outer shell 10 is waist-shaped. This improves the structural strength and noise reduction effect of the outer shell 10.

[0251] In this embodiment, as Figures 33-34 As shown, the cross-section of the outer shell 10 is shaped like a peanut shell.

[0252] Furthermore, such as Figures 6 to 10 As shown, the lifting flange 31 is disposed at the narrower end of the upper cover 30. It can be understood that by disassembling the upper cover 30 by placing the lifting flange 31 at the narrower end of the upper cover 30, the force on the lifting flange 31 can be reduced when the user removes the upper cover 30 by grasping the lifting flange 31. This not only facilitates the removal of the upper cover 30, but also reduces the risk of damage and deformation to the lifting flange 31, thereby increasing its service life.

[0253] Furthermore, such as Figure 2 , Figure 5 ,and Figure 15As shown, the housing assembly 100 further includes a middle shell 20, which includes a plurality of hollow support columns 22 for connecting the base shell 21 and for installing the filter element 200 of the water purification equipment 1000. The connecting base shell 21 includes a base plate 211 and a surrounding plate 212 disposed around the base plate 211. The hollow support columns 22 protrude downward on the base plate 211. The middle shell 20 is installed inside the outer shell 10.

[0254] Specifically, the inner side of the enclosure 212 is inclined outward from bottom to top, and the inner side of the upper cover 30 is provided with an annular limiting protrusion 32. The outer ring surface of the annular limiting protrusion 32 is inclined inward from top to bottom. The annular limiting protrusion 32 is located on the inner side of the enclosure 212, and the outer ring surface of the annular limiting protrusion 32 is adapted to abut against the inner side of the enclosure 212.

[0255] It is understood that, through the above structural design, when the top cover 30 is assembled, the inner surface of the surrounding plate 212 can guide the annular limiting protrusion 32, thereby facilitating the assembly of the top cover 30. Furthermore, when assembling the top cover 30 from one side (i.e., assembling one side of the top cover 30 first, and then pressing down on the opposite side), the outer ring surface of the annular limiting protrusion 32 will interfere with the inner surface of the surrounding plate 212 to a small extent, thus improving the user's feel when assembling the top cover 30. When removing the top cover 30 from one side, the outer ring surface of the annular limiting protrusion 32 will interfere with the inner surface of the surrounding plate 212 to a small extent, thus not only improving the user's feel when removing the top cover 30, but also reducing the risk of the top cover 30 accidentally falling off.

[0256] Specifically, such as Figure 19 As shown, the base plate 211 has a clearance through hole 2111 communicating with the inner cavity of the hollow support column 22; the outer peripheral surface of the surrounding plate 212 is adapted to abut against the inner wall surface of the outer shell 10. Thus, by providing the surrounding plate 212, not only can the contact area between the upper end of the middle shell 20 and the inner wall surface of the outer shell 10 be increased, thereby enhancing the assembly stability of the middle shell 20, but the structural strength of the connecting base plate 211 can also be enhanced, thereby strengthening the structural strength of the middle shell 20 and the shell assembly 100.

[0257] Furthermore, such as Figure 19 As shown, a recess 2112 is provided in the middle of the substrate 211, and the hollow support column 22 is disposed in the recess 2112. This enhances the structural strength of the substrate 211, thereby enhancing the structural strength of the inner shell 20. Furthermore, by providing the recess 2112 in the middle of the substrate 211, installation space can be provided for the water circuit components of the water purification device 1000.

[0258] It is understood that the projection of the connecting substrate 211 on the horizontal plane is consistent with the projection of the outer shell 10, both being elliptical, peanut-shell-shaped, or waist-shaped, to facilitate the installation of the middle shell 20.

[0259] Specifically, such as Figure 20 As shown, the outer shell 10 also has a lower opening, that is, the outer shell 10 is a hollow structure with openings at both ends. This not only facilitates the forming of the outer shell 10, but also facilitates the installation of internal structures such as the middle shell 20.

[0260] In this embodiment, the outer shell 10 is integrally injection molded.

[0261] Specifically, such as Figure 33 and Figures 39-40 As shown, the housing assembly 100 also includes a base 40, which covers the lower opening of the housing 10.
