[0060] DETAILED DESCRIPTION

[0061] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0062] Refer to the following Figure 1-Figure 12 The housing assembly 100 according to an embodiment of the present invention is described. The housing assembly 100 may include but is not limited to a plastic part, which forms a basic framework of the water purification device 1000. The housing assembly 100 is used to load functional components such as a filter element and a booster pump.

[0063] Usually, if Figure 1As shown, the housing assembly 100 includes: an outer shell 10, a middle shell 20 and a base 40, wherein the middle shell 20 is received in a chamber defined by the outer shell 10, for example, Fig.13 As shown, the outer shell 10 is a hollow frame structure with both upper and lower ends open, and the base 40 is used to close the lower end of the outer shell 10, so as to facilitate the assembly and disassembly of the outer shell 10 and the middle shell 20, and the outer shell 10 and the base 40, thereby improving the assembly efficiency of the water purification equipment 1000.

[0064] Specifically, the middle shell 20 includes a connecting base shell 21 and a hollow support column 22 vertically formed at the bottom of the connecting base shell 21 and extending downward in the vertical direction. The bottom of the hollow support column 22 is circumferentially provided with a first connecting member. The base 40 is provided with a second connecting member that cooperates with the first connecting member. One of the first connecting member and the second connecting member is a positioning column, and the other is a positioning groove. When the middle shell 20 and the base 40 are assembled, the first connecting member and the second connecting member can be aligned first, and then the positioning column can be embedded in the positioning groove to realize the connection between the middle shell 20 and the base 40. In order to make the middle shell 20 and the base 40 fit securely, the positioning column and the positioning groove can be interference fit.

[0065] According to the shell assembly 100 for the water purification device 1000 of the embodiment of the present invention, the middle shell 20 and the base 40 can be quickly assembled by cooperating with the first connecting member and the second connecting member, thereby improving the assembly efficiency of the shell assembly 100.

[0066] In an optional embodiment, the first connecting member is a positioning column 221, and the second connecting member is a positioning groove 4311. The positioning column 221 is cylindrical and has a center hole 2211 opening downward. The positioning groove 4311 has a through hole 421 penetrating the upper and lower surfaces of the base 40, and the through hole 421 corresponds to the center hole 2211. Figure 1 Combination Figure 2 , Figure 3 Combination Figure 4 and Figure 5 The positioning column 221 and the positioning groove 4311 are both cylindrical, and the cylindrical positioning column 221 is inserted into the cylindrical positioning groove 4311 to achieve the matching of the middle shell 20 and the base 40. In order to improve the stability of the matching between the middle shell 20 and the base 40, a plurality of positioning columns 221 can be arranged around the bottom of the hollow support column 22, and correspondingly, a plurality of positioning grooves 4311 are also arranged on the base 40.

[0067] In addition, a pin or a screw (not shown) can be inserted into the through hole 421 and the center hole 2211, and the pin or the screw extends from the lower surface of the base 40 into the through hole 421 and the center hole 2211 in sequence, thereby further improving the reliability of the cooperation between the middle shell 20 and the base 40 and preventing the middle shell 20 and the base 40 from loosening during transportation or handling.

[0068] In further optional examples, such as Figure 6 and Figure 7 As shown, the base 40 is provided with a plurality of bosses 43 in the circumference, and the positioning groove 4311 is formed on the boss 43. Among them, the positioning groove 4311 can be formed by the upper surface of the boss 43 being depressed downward or by the upper surface of the boss 43 protruding upward. In other words, the base 40 protrudes upward to form a boss 43 higher than the upper surface, so that the bottom surface of the positioning groove 4311 can be higher than the upper surface of the base 40. In this way, when the positioning column 221 and the positioning groove 4311 are connected and matched, the middle shell 20 and the base 40 can be separated in the vertical direction, so that an airflow channel 80 can be formed between the middle shell 20 and the base 40, which facilitates the timely discharge of heat released by other electronic devices such as the booster pump. In addition, since the airflow channel 80 is relatively unobstructed, when the humidity in the shell assembly 100 is relatively serious, the evaporated water can also be discharged in time.

[0069] In further optional examples, such as Figure 6 and Figure 7 As shown, an annular platform 431 is formed on the boss 43, and the annular platform 431 defines a positioning groove 4311 opening upward, and the through hole 421 passes through the upper surface and the lower surface of the boss 43. That is, the annular platform 431 is formed on the upper surface of the boss 43 to protrude upward, and the positioning column 221 is inserted into the positioning groove 4311 defined by the annular platform 431. Therefore, the horizontal height of the middle shell 20 is raised by the boss 43, ensuring that the middle shell 20 and the base 40 form an airflow channel 80, and the airflow channel 80 is opposite to the wire slot of the outer shell 10, which is convenient for the arrangement of the line.

[0070] In a specific embodiment, Figure 6 and Figure 7 As shown, the boss 43 is an oblong. That is, at least a portion of the projection of the boss 43 on the horizontal plane is an arc. For example, the projection of the boss 43 on the horizontal plane is an ellipse, or the projection of the boss 43 on the horizontal plane has arcs at both ends and a horizontal straight line in the middle. Of course, it can be understood that the above is only schematic and is not a limitation on the shape of the boss 43 in the embodiment of the present invention. The projection of the boss 43 on the horizontal plane can be a triangle, a quadrilateral, a hexagon or a circle, and the projection of the boss 43 on the horizontal plane can also be an irregular shape.

[0071] In a further optional example, a portion of the positioning column 221 is inserted into the positioning groove 4311. In other words, another portion of the positioning column 221 is not inserted into the positioning groove 4311. Figure 4 and Figure 5As shown, the spacing distance q between the middle shell 20 and the base 40 is equal to the sum of the height t1 of the boss 43 and the length t2 of the positioning column. It can be understood that, when the depth of the positioning groove 4311 is fixed, the more the portion of the positioning column 221 that is not inserted into the positioning groove 4311, the greater the spacing distance between the middle shell 20 and the base 40. Similarly, the greater the height t1 of the boss 43, the greater the spacing distance between the middle shell 20 and the base 40. In other words, the distance between the middle shell 20 and the base 40 can be adjusted by adjusting the size of t1 and t2.

[0072] It is understandable to those skilled in the art that when the water purification device 1000 is placed directly on the countertop, it is easy to scratch the countertop when the water purification device 1000 needs to be moved or cleaned. In particular, for countertops made of artificial quartz stone, once scratched, it is easy for color to seep, making it very difficult to repair the countertop.

[0073] Therefore, in some optional embodiments of the present invention, a groove 44 is provided on the lower surface of the base 40 at a position corresponding to the boss 43, and a flexible foot pad 60 is provided in the groove 44, wherein the flexible foot pad 60 can be made of materials such as rubber or silicone. Since the friction coefficient of the flexible foot pad 60 is relatively large, the static friction between the shell component 100 and the table surface can be increased, so that the shell component 100 can be stably placed on the table surface, and when the shell component 100 needs to be transported or moved, the flexible foot pad 60 contacts the table surface, and the flexible foot pad 60 has a certain deformation ability and buffering ability, which can prevent the shell component 100 from scratching the table surface, or the table surface from scratching the shell component 100, and plays a certain anti-scratch protection role. And the flexible foot pad 60 is plugged into the groove 44, and this connection method is simple and convenient for replacement and installation.

[0074] In addition, when the water purification equipment 1000 is running, the flexible foot pad 60 plays a role in buffering and shock absorption, preventing the internal components of the water purification equipment 1000 from falling off under the influence of long-term vibration, which is beneficial to improving the stability of the water purification equipment 1000. In addition, since the shell assembly 100 of the water purification equipment 1000 is in flexible contact with the table top, it can also reduce noise and improve environmental quality.

[0075] In an optional embodiment, the flexible foot pad 60 includes a pressure plate 61 and a plurality of mounting ears 62. Fig.10 Combination Fig.11 As shown, a plurality of mounting ears 62 are formed on the side of the pressing plate 61 facing the base 40, and the mounting ears 62 have a bayonet 621. A card 441 that matches the bayonet 621 is formed in the groove 44. That is, when the flexible foot pad 60 is inserted into the groove 44, the card 441 is embedded in the bayonet 621, thereby preventing the flexible foot pad 60 from falling off from the groove.

[0076] In a further optional example, the flexible foot pad 60 has two mounting ears 62, and the two mounting ears 62 are respectively located at both ends of the pressure plate 61. When the flexible foot pad 60 is inserted into the groove 44, the wall surface of the mounting ear 62 fits with the wall surface of the groove 44, thereby further firmly embedding the flexible foot pad 60 in the groove 44 to prevent it from falling off.

[0077] In addition, if Figure 4 Combination Figure 5 As shown, the pressure plate 61 is directly opposite to the through hole 421 of the boss 43. In this way, when a pin or a screw is provided in the through hole 421 of the boss 43 and the center hole 2211 of the positioning column 221, the pressure plate 61 can also play the role of shielding the pin and the screw, which can not only improve the appearance quality of the shell assembly 100, but more importantly, can isolate the pin or the screw from the outside world to prevent it from being oxidized and rusted, thereby further improving the stability of the structure of the shell assembly 100.

[0078] In further optional examples, such as Fig.11 As shown, the pressing plate 61 is provided with two spaced mounting ears 62, and a grid 611 is provided on the side of the pressing plate 61 between the two mounting ears 62 facing the base 40. In other words, the grid 611 is provided in the middle of the pressing plate 61, so that when the pressing plate 61 is squeezed or stabbed by external force, the pressing plate 61 can be partially damaged, and destructive fracture will not occur in the middle of the pressing plate 61. In addition, the mutual pulling of multiple grids 611 can effectively improve the anti-deformation ability of the pressing plate 61.

[0079] In further optional examples, such as Figure 3 Combination Figure 4 ,like Fig.10 As shown, the lower surface of the base 40 is a smooth surface, and the pressing plate 61 protrudes from the lower surface of the base 40. In this way, the portion of the housing assembly 100 that contacts the table is only the portion of the pressing plate 61 that protrudes from the lower surface of the base 40, thereby preventing the lower surface of the base 40 from contacting the table, and preventing the base 40 and the table from being damaged by scratching each other.

[0080] In further optional examples, such as Figure 1 , Figure 6 , Fig. 9 and Fig.10 As shown, the base 40 is provided with a drainage hole, and an isolation plate 46 is provided around the drainage hole 45. The isolation plate 46 is provided on the upper surface of the base 40 and extends upward. In this way, if there is water on the upper surface of the base 40, the water can be discharged from the drainage hole 45 to the outside, and the housing assembly 100 can be kept dry. In addition, the heat released by the heating element in the water purification device 1000, such as the booster pump or other electronic components, can also be discharged from the drainage hole.

[0081] In an optional embodiment, if Fig.14Combination Fig.16 As shown, the housing 10 of the housing assembly 100 for the water purification device 1000 includes a first side wall 11, a second side wall 12, a third side wall 14 and a fourth side wall 15 connected in sequence, and the first side wall 11 and the second side wall 12 are relative to the first direction (such as Fig.16 The third side wall 14 and the fourth side wall 15 are symmetrically arranged relative to the second direction (such as Fig.16 The first side wall 11, the second side wall 12, the third side wall 14 and the fourth side wall 15 are symmetrically arranged, and the connecting parts of the first side wall 11, the second side wall 12, the third side wall 14 and the fourth side wall 15 are smoothly connected, and at least two opposite side walls of the first side wall 11, the second side wall 12, the third side wall 14 and the fourth side wall 15 are arc-shaped walls.

[0082] For example, refer to Fig.16 , from the top view direction, the housing 10 is an oblong structure, the first side wall 11 and the second side wall 12 are located at the front and rear sides, and the third side wall 14 and the fourth side wall 15 are located at the left and right sides, wherein the first side wall 11 and the second side wall 12 may be arc-shaped walls, or the third side wall 14 and the fourth side wall 15 may be arc-shaped walls, or the first side wall 11 and the second side wall 12, the third side wall 14 and the fourth side wall 15 may all be arc-shaped walls. That is, at least a portion of the wall surface of the housing 10 is a curved surface, for example, an arc surface. The projection of the housing 10 on the horizontal plane may be an oblong, for example, an ellipse.

[0083] Since the first side wall 11 , the second side wall 12 , the third side wall 14 and the fourth side wall 15 are connected in a smooth transition, the outer wall surface and the inner wall surface of the shell 10 are relatively smooth and rounded, which can improve the structural strength of the shell 10 .

[0084] Of course, the housing 10 of the embodiment of the present invention is not limited to the above-mentioned oblong structure, and the arc-shaped wall of the housing 10 is not limited to Fig.15 As shown in FIG. 1 , the arc-shaped wall is convex outwardly away from the center of the housing 10 , and the arc-shaped wall may also be convex inwardly toward the center of the housing 10 .

[0085] Since at least two opposite side walls of the housing 10 are arc-shaped walls, the housing 10 has a stronger ability to resist deformation, improves its structural strength, is more resistant to external impacts, and increases the service life of the housing 10.

[0086] According to the shell assembly 100 for the water purification device 1000 of an embodiment of the present invention, by setting at least two opposite side walls of the outer shell 10 as arc-shaped walls, the horizontal distance of the outer shell 10 in the first direction and / or the second direction can be appropriately reduced, so that the structural strength of the outer shell 10 is stronger and the space occupied is small, and the various components of the water purification device 1000 can also be compactly arranged in the outer shell 10, thereby improving the structural strength of the outer shell 10 and avoiding hollowing and damage during transportation and handling.

[0087] In an optional embodiment, if Fig.16 As shown, the perimeters of the first side wall 11 and the second side wall 12 are greater than the perimeters of the third side wall 14 and the fourth side wall 15. In other words, the horizontal distance of the housing 10 in the first direction is smaller than the horizontal distance in the second direction, that is, the housing 10 in the first direction is smaller than the horizontal distance in the second direction. Fig.15 The extension distance in the left-right direction is greater than the extension distance in the front-back direction.

[0088] In an optional embodiment, if Fig.14 Combination Fig.16 As shown, the outer wall surfaces of the first side wall 11 and the second side wall 12 are planes, and the wall surfaces of the third side wall 14 and the fourth side wall 15 are convex in the direction away from the center of the shell 10. In other words, the third side wall 14 and the fourth side wall 15 are arc-shaped walls, and the first side wall 11 and the second side wall 12 are straight surfaces. From the top view direction, the shell 10 is an oblong. In other words, a part of the wall surface of the shell 10 is a plane, and the other part is a curved surface. Among them, the third side wall 14 and the fourth side wall 15 are located at the left and right ends of the shell 10, and the second side wall 12 and the fourth side wall 15 are located at the front and back sides of the middle part of the shell 10. Since the third side wall 14 and the fourth side wall 15 are arc-shaped walls, they have strong anti-deformation ability, the first side wall 11 and the second side wall 12 are straight structures, and the structure is relatively stable. The first side wall 11 and the second side wall 12 and the third side wall 14 and the fourth side wall 15 can compensate each other, thereby better improving the structural stability of the shell 10 and preventing the shell 10 from excessive deformation.

[0089] In an optional embodiment, refer to Fig.16 , the center angle α of the third side wall 14 and the fourth side wall 15 is between 30-180°. In this embodiment, the "center angle" refers to the angle of the circle corresponding to the cross section of the third side wall 14 and the fourth side wall 15, that is, from the top view direction, the third side wall 14 and the fourth side wall 15 can be semicircular or arcuate. For example, the center angle of the third side wall 14 and the center angle of the fourth side wall 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 side wall 14 and the fourth side wall 15 is fixed, the larger the center angle of the third side wall 14 and the fourth side wall 15, the larger the horizontal spacing between the first side wall 11 and the second side wall 12, and the larger the spatial volume defined by the shell 10. On the contrary, the smaller the central angle of the third side wall 14 and the fourth side wall 15 is, the smaller the horizontal distance between the first side wall 11 and the second side wall 12 is, and the smaller the space volume defined by the housing 10 is. In this way, the size of the housing 10 can be adjusted according to the size of each component to be placed, so that each component is arranged in an orderly and compact manner in the housing 10.

[0090] In an optional embodiment, refer to Fig.14 , Fig.16, Fig.18 and Fig. 20 The first side wall 11, the second side wall 12, the third side wall 14 and the fourth side wall 15 form a cavity with both upper and lower ends open, and the shell assembly 100 also includes: a middle shell 20, and the middle shell 20 is built in the cavity. That is, the outer shell 10 is a hollow frame structure, and the cavity can be used to install and position components such as the middle shell 20. In other words, the shell assembly 100 generally includes the outer shell 10 located on the outside and the middle shell 20 located on the inside.

[0091] Specifically, Fig.19 , Fig.21 and Fig. 22 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 escape holes 2111 penetrating the top and bottom surfaces thereof. The hollow support columns 22 are formed at the bottom of the connecting base shell 21 and correspond to the escape holes 2111. The hollow support columns 22 are formed from one side (such as Fig.21 The upper side of the middle shell 20) to the other side (such as Fig.21 The structure extends in a direction of the lower side of the middle shell 20.

[0092] It is understandable that, since the shape and structure of the connecting base shell 21 match the outer shell 10 , the inner wall surface of the outer shell 10 and the outer wall surface of the middle shell 20 better match and lean against each other to form the shell structure of the shell assembly 100 .

[0093] The hollow support column 22 divides the cavity into a plurality of independent installation and positioning spaces. For example, a filter element, a water pump or an adapter can be placed in the hollow support column 22. For example, the filter element can be placed in the hollow support column 22 through the avoidance hole 2111.

[0094] In addition, the hollow support column 22 may include one, two or more than two, for example, Figure 18-Figure 20 As shown, there are two hollow support columns 22, which are arranged side by side and spaced apart. It is understandable that the above is only for illustration and is not a limitation of the embodiment of the present invention. The number of hollow support columns 22 can be three, which are formed side by side in a line at the bottom of the connecting base shell 21.

[0095] In the optional example, Fig.18 Combination Fig. 20 , the projection of the connecting base shell 21 on the horizontal plane covers the projection of the hollow support column 22 on the horizontal plane. In other words, the outer periphery of the connecting base shell 21 exceeds the outer periphery of the hollow support column 22, and after the middle shell 20 is built into the cavity, the outer side surface of the connecting base shell 21 is closer to the inner wall surface of the outer shell 10 than the outer side surface of the hollow support column 22.

[0096] In the optional example, Figure 19-21 As shown, a plurality of hollow support columns 22 are arranged at intervals, and a structural reinforcement member 50 is provided between two hollow support columns 22, and the two ends of the structural reinforcement member 50 are respectively connected to the outer circumference of the two hollow support columns 22. In other words, one end of the plurality of hollow support columns 22 (such as Fig.21 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 (such as Fig.21 The lower end of the hollow support column 22 is connected to the structural reinforcement 50, so that even when the filter element and other components are loaded in the hollow support column 22, various forces can be dispersed on the structural reinforcement 50 and the connecting base shell 21, thereby improving the stability of the internal structure of the housing assembly 100. In addition, the structural reinforcement 50 can be arched, and the arched structural reinforcement 50 provides a larger force-bearing surface, thereby further improving the stability of the housing assembly 100 structure.

[0097] In the optional example, Fig.14 Combination Figure 15-16 As shown, the inner wall surface of the outer shell 10 is formed with a plurality of spaced convex ribs 19, and the convex ribs 19 and the inner wall surface of the outer shell 10 form a notch 191, and the top of the connecting base shell 21 is provided with a latch 213 that matches the notch 191. That is, the outer shell 10 and the middle shell 20 are connected by the latch 213 matching the notch 191.

[0098] The rib 19 may extend along the longitudinal direction of the housing 10. Fig.14 As shown, the ribs 19 may also extend along the circumferential direction of the housing 10, which is not shown. By providing a plurality of ribs 19 on the inner circumferential wall of the housing 10, the structural strength of the housing 10 can be effectively improved, and the pressure resistance of the housing 10 can be improved.

[0099] In a specific embodiment, referring to Fig.24 Combination Fig.25 As shown, the latch 213 is arranged at the outer peripheral edge of the connecting base shell 21 and extends downward, and the top surface of the convex rib 19 is recessed downward to form a notch 191 opening upward, and the latch 213 is inserted into the notch 191. That is, the latch 213 is inserted into the notch 191 from top to bottom, so that the middle shell 20 is suspended on the outer shell 10. The latch 213 and the notch 191 can be clearance or interference fit.

[0100] In a specific example, Fig.14 Combination Fig.15As shown, the convex ribs 19 include a plurality of convex ribs 19, and the plurality of convex ribs 19 are distributed on at least one of the first side wall 11, the second side wall 12, the third side wall 14, and the fourth side wall 15. In other words, the plurality of convex ribs 19 can be formed on the first side wall 11 and / or the second side wall 12 and / or the third side wall 14 and / or the fourth side wall 15. Preferably, the plurality of groups of convex ribs 19 are evenly distributed on the first side wall 11, the second side wall 12, the third side wall 14, and the fourth side wall 15. Accordingly, the outer periphery of the connecting base shell 21 is also evenly distributed with the latch tongues 213. Thus, through the corresponding cooperation of the plurality of latch tongues 213 and the plurality of notches 191, the middle shell 20 can be relatively stably arranged in the cavity.

[0101] In addition, the ribs 19 evenly distributed on the inner wall of the shell 10 can also enhance the overall strength of the shell 10 . Preferably, the length of the ribs 19 is substantially consistent with the longitudinal length of the wall of the shell 10 .

[0102] In a further optional example, two convex ribs 19 form a group, and one latch 213 corresponds to one group of convex ribs 19. That is, one latch 213 is embedded in two notches 191 at the same time. In this way, the force of the latch 213 can be dispersed on the two convex ribs 19, avoiding the problem of the convex ribs 19 breaking.

[0103] In further optional examples, such as Fig.17 As shown, the horizontal spacing l between two adjacent convex ribs 19 is between 1.5-3.5 mm. The spacing between two adjacent convex ribs 19 is the distance between the side of one convex rib 19 and the side of another convex rib 19. For example, the width of the horizontal spacing l is 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm or 3.5 mm. Of course, the above embodiments are only exemplary and cannot be understood as limiting the scope of protection of the present invention. For example, the spacing between the two convex ribs 19 can also be less than 1.5 mm or greater than 3.5 mm. That is, the horizontal spacing between the two convex ribs 19 can be adjusted accordingly according to the change in the size of the housing 10.

[0104] In further optional examples, such as Fig.15 Combination Fig.19 As shown, the rib 19 includes: a connecting section 192 and a cylindrical section 193. The connecting section 192 is connected between the inner wall surface of the outer shell 10 and the cylindrical section 193, and has the function of bearing the middle shell 20 and reinforcing the structural strength of the outer shell 10. When the middle shell 20 is inserted into the cavity, the cylindrical section 193 can play a guiding role, and can also abut against the outer peripheral surface of the middle shell 20 to play a limiting role. Therefore, there are relatively special requirements for the dimensions of the cylindrical section 193 and the connecting section 192.

[0105] Specifically, Fig.15 Combination Fig.17As shown, the radial dimension r of the cross section of the cylindrical section 193 is between 1-2 mm. For example, the diameter of the cylindrical section 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. The diameter of the cylindrical section 193 is set between 1-2 mm. The volume of the cylindrical section 193 is small, and it does not occupy the accommodating cavity, and it can also achieve the functions of guiding and positioning. In addition, the strong pressure resistance can prevent the cylindrical section 193 from breaking or deforming inward. Of course, according to actual conditions, the diameter of the cylindrical section 193 can be appropriately increased or reduced. For example, the diameter of the cylindrical section 193 can also be between 0.5 mm and 1.0 mm, or the diameter of the cylindrical section 193 can be between 2.0 mm and 5 mm.

[0106] The horizontal width d1 of the connecting section 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 section 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 of the connecting section 192 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 bearing capacity and compressive resistance of the connecting section 192.

[0107] The water purification device 1000 according to the embodiment of the present invention includes the shell assembly 100 of the above embodiment. Since the shell assembly 100 according to the embodiment of the present invention has high structural strength and small volume, the water purification device 1000 according to the embodiment of the present invention has high structural strength and small volume.

[0108] Reference Figure 22-Figure 26 A water purification device 1000 according to other embodiments of the present invention is described.

[0109] The present invention provides a water purification device 1000, which can be a water purifier, a water purification device 1000 or the like. Fig. 22 Combination Fig.24 As shown, the middle shell 20 of the water purification equipment 1000 has two filter element cavities d arranged side by side, that is, each hollow support column 22 defines a filter element cavity d, and a water pump 71 is installed at one end of the vertical direction of the middle shell 20, and the length direction of the water pump 71 is the same as the horizontal direction of the middle shell 20, so the arrangement of the two is more compact, so that the overall volume of the water purification equipment 1000 can be set smaller.

[0110] See also Figure 22 to Figure 24 The present invention proposes a water purification device 1000, which includes a shell 10, and the shell 10 is placed in a vertical direction when the water purification device 1000 is in use, so the vertical direction of the shell 10 is consistent with the up and down direction of the space. The shape of the shell 10 is specifically set according to different needs. In the present application, the shell 10 includes a cylindrical shell 10, an upper cover (not shown) covered on the upper end of the shell 10, and a base 40 at the lower end, so that the shell 10, the upper cover and the base 40 form an accommodating space. Among them, the cross section of the shell 10 is set in an 8-shaped shape, that is, the two side plates with a longer width of the shell 10 are concave with arc grooves extending up and down, and the setting of the arc groove is first to strengthen the strength of the shell 10, and secondly to make the inner surface of the shell 10 form multiple arc transitions to achieve a better noise reduction effect. In addition, a middle shell 20 is installed in the accommodating space of the shell 10, and a filter element is installed in the middle shell 20, and then the filter element filters the incoming water.

[0111] Specifically for the middle shell 20, a filter cartridge cavity d is provided on the middle shell 20, and the filter cartridge cavity d may be provided with one or more. When multiple filter cartridge cavities d are provided, the arrangement of the multiple filter cartridge cavities d may be determined according to different requirements. In the present application, two filter cartridge cavities d are provided on the middle shell 20, and the two filter cartridge cavities d extend in the up-down direction and are arranged side by side, so that the arc groove on the outer shell 10 corresponds to the interval between the two filter cartridge cavities d, so as to cooperate with the above-mentioned outer shell 10 to make the assembly more compact.

[0112] In addition, if Fig.23 and Fig.24 As shown, a water pump 71 is installed in the housing 10, and the water pump 71 is installed horizontally at one end of the vertical direction of the middle shell 20. It should be explained here that the water pump 71 is placed horizontally, that is, the length direction of the water pump 71 is consistent with the horizontal direction of the middle shell 20, so it is equivalent to placing the middle shell 20 vertically on the water pump 71, so that the internal space of the water purification equipment 1000 is compactly arranged to achieve a miniaturized setting. Among them, the water pump 71 can be installed at the upper end of the middle shell 20, or it can be installed at the lower end of the middle shell 20. In this application, it is preferred to install the water pump 71 at the lower end of the middle shell 20. Therefore, considering that the filter element of the present application is to be extracted from the upper end of the middle shell 20 when cleaning or replacing, if the water pump 71 is installed at the upper end of the middle shell 20, it will interfere with the removal of the filter element; in addition, the weight of the water pump 71 is heavy, so installing the water pump 71 at the lower end of the middle shell 20 can lower the overall center of gravity of the water purification equipment 1000 and achieve a stable placement effect.

[0113] In the technical solution of the present invention, the water purification device 1000 includes a housing 10, a middle housing 20 is vertically installed in the housing 10, and the middle housing 20 has two filter element cavities set up horizontally. Secondly, a water pump 71 is also installed in the housing 10, and the water pump 71 is installed at the upper end or the lower end of the middle housing 20, and the water pump 71 is arranged horizontally, that is, the length direction of the water pump 71 is consistent with the horizontal direction of the middle housing 20, so that the assembly of the two is more compact, and the internal space of the water purification device 1000 is reasonably arranged to achieve a miniaturized setting.

[0114] In the above embodiment, the water pump 71 is preferably installed at the lower end of the middle shell 20. Specifically, the water pump 71 can be connected to the lower end of the middle shell 20, that is, the water pump 71 is connected to the middle shell 20; or, the water pump 71 is connected to the bottom of the outer shell 10 for fixation, and is located at the lower end of the middle shell 20. In these two methods, when the water pump 71 is connected to the middle shell 20, since the vibration generated by the water pump 71 when working is relatively large, directly connecting the water pump 71 to the middle shell 20 will cause a large transmission to the middle shell 20 and affect the filter element; when the water pump 71 is directly connected to the bottom of the outer shell 10, the vibration of the water pump 71 will also directly exceed the outer shell 10 and cause the overall shaking of the water purification equipment 1000 to be relatively large, and also cause relatively large noise to be generated. Therefore, in another embodiment, please refer to Fig. 22 The water purification device 1000 further includes a base 40, which is installed at the lower end of the middle shell 20 to enclose the middle shell 20 to form an installation cavity, and the water pump 71 is installed in the installation cavity. Fig.25 Combination Fig.26 The water pump housing 41 includes a bottom plate 41a and an annular plate 41b erected along the periphery of the bottom plate 41a, so that the water pump housing 41 has an upper opening, and the upper end of the water pump housing 41 is connected to the middle housing 20 to form a relatively closed cavity, or a completely closed cavity. The water pump 71 is installed in the installation cavity formed by the water pump housing 41 and is connected to the inner bottom surface of the base 40, thereby effectively increasing the vibration transmission resistance and noise transmission resistance of the water pump 71. In addition, it should be noted that the water pump housing 41 is located in the outer housing 10.

[0115] In order to further reduce the vibration propagation of the water pump 71, in another embodiment, see Fig.25 The lower part of the water pump 71 is connected with a mounting seat 74, and the water pump 71 is mounted on the water pump housing 41 through the mounting seat 74. It is easy to understand that the mounting seat 74 is fixed to the inner surface of the water pump housing 41, and then the water pump 71 is supported by the mounting seat 74, which is equivalent to the water pump housing 41 supporting the water pump 71, so the mounting seat 74 can initially reduce the vibration of the water pump 71.

[0116] Furthermore, in order to achieve a better shock absorption effect, a plurality of shock-absorbing support pads 75 are provided on the mounting seat 74, and the plurality of shock-absorbing support pads 75 support the mounting seat 74. Therefore, when the water pump 71 is working, the shock-absorbing support pads 75 can further reduce the shock of the water pump 71 to reduce the vibration propagation of the water pump 71.

[0117] Considering that the water pump 71 generates vibrations during operation, cracks may easily appear at the water inlet of the water pump 71, resulting in water leakage. Fig.26 In another preferred embodiment, a drainage hole 45 is provided on the bottom surface of the water pump housing 41, so that when the water pump 71 leaks, the liquid can be discharged through the drainage hole 45 on the water pump housing 41 to avoid the liquid interfering with the wires connecting the water pump 71.

[0118] In any of the above embodiments, since the water pump 71 is connected to the waterway plate 72, the waterway plate 72 is equipped with components such as a pressure switch 73, for details, refer to Fig.23 Therefore, when the water pump 71 is installed on the water pump housing 41, the water pump housing 41 will interfere with the installation of the waterway plate 72 and the pressure switch 73, thereby affecting the installation of the waterway plate 72 and the pressure switch 73. Fig.25 and Fig.26 In this embodiment, a clearance gap a is provided on one side of the waterway plate 72 corresponding to the annular plate 41b of the water pump housing 41, so that the waterway plate 72 and the pressure switch 73 can be installed in the clearance gap a.

[0119] Furthermore, in order to reduce the influence of the opening of the clearance gap a on the overall noise reduction effect of the water pump housing 41, in another preferred embodiment, the water pump housing 41 is provided with a first cover plate (not shown in the figure), which covers the clearance gap a of the annular plate 41b and is detachably connected to the annular plate 41b. It is easy to understand that since the original parts such as the waterway plate 72 are placed at the clearance gap a, when the first cover plate covers the clearance gap a, the first cover plate itself has a certain accommodation position for accommodating the waterway plate 72 and other components, for example, the cover accommodation space is formed by the depression of the plate surface of the first cover plate, or the first cover plate is set with a certain curvature, so it can be surrounded at the clearance gap a to block the clearance gap a.

[0120] Before using the water purification device 1000, the air tightness of the water purification device 1000 is generally tested to prevent water leakage during use of the water purification device 1000. The general testing method is to fill the water pump 71 and each water path with test gas, and then use a test probe to approach the water inlet and outlet of the water pump 71 (such as Fig.23As shown, the adjacent water inlet is set), and the connection port connecting the waterway plate 72 is tested to see if there is any air leakage. In this regard, based on the above embodiment, since the water pump housing 41 and the middle housing 20 cooperate to form a closed cavity for placing the water pump 71, when the inspector tests the air tightness of the water purification equipment 1000, it is necessary to open the water pump housing 41 and then move the monitoring head close to the flow path structure of the water pump 71, which is more troublesome. Therefore, please refer to Fig.25 and Fig.26 In this embodiment, a first inspection port b is provided on the annular plate 41b of the water pump housing 41 for exposing the water inlet and the water outlet e of the water pump 71. When the inspector needs to inspect the water inlet and the water outlet e of the water pump 71, the inspector can directly insert the inspection head into the first inspection port b for inspection. Furthermore, in order to facilitate the inspector to perform air tightness inspection on the connection port between the water pump 71 and the waterway plate 72, a second inspection port c is provided on the enclosure 42 for exposing the connection port between the water pump 71 and the waterway plate 72. Therefore, when the inspector needs to inspect the connection port between the water pump 71 and the waterway plate 72, the inspector can directly insert the inspection head into the second inspection port c for inspection.

[0121] Furthermore, the opening of the first inspection port b and the second inspection port c will affect the noise reduction ability of the water pump housing 41. Therefore, in another embodiment, the water pump housing 41 is provided to further include a first cover plate (not shown in the figure), the first cover plate covers the first inspection port b, and is detachably connected to the enclosure 42; and / or the water pump housing 41 further includes a second cover plate, the second cover plate covers the second inspection port c, and is detachably connected to the annular plate 41b. Preferably, the first inspection port b and the second inspection port c are both covered by a cover plate, so when it is necessary to conduct an air tightness test on the water purification equipment 1000, the first cover plate and the second cover plate are first disassembled to expose the area to be tested. After the test is completed, the first cover plate and the second cover plate are respectively closed corresponding to the first inspection port b and the second inspection port c, thereby avoiding the opening of the inspection port from affecting the noise reduction effect of the base 40.

[0122] There are many ways to disassemble and connect the first cover plate and the second cover plate, so they are not described in detail. And the disassembly methods are common knowledge in the field, so the disassembly methods that are easy to think of or obtained by reasonable reasoning by those skilled in the art are within the protection scope of this application.

[0123] Based on any of the above embodiments, please refer to Fig. 22, further describing the shell 10 of the water purification device 1000, the shell 10 comprises a shell 10 with upper and lower openings, an upper cover plate covering the upper opening of the shell 10, and a base 40 covering the lower opening of the shell 10; wherein the shell 10 is arranged in a cylindrical shape. It should be explained that the shell 10, the upper cover plate and the base 40 enclose a closed cavity, the water pump shell 41 is installed in the cavity, and the water pump 71 is installed in the water pump shell 41, and then the noise generated by the water pump 71 is first blocked and reduced by the water pump shell 41, and then blocked by the shell 10, thereby reducing the working noise of the water purification device 1000. It should also be explained that the shell 10 is arranged in a cylindrical shape, which can be understood as the surface of the shell 10 is smoothly transitioned in its circumferential direction, that is, each corner in the circumferential direction is rounded, so it can achieve a better noise reduction effect.

[0124] Furthermore, in order to make the overall assembly of the water purification equipment 1000 more compact and reduce the overall volume. Therefore, in this embodiment, arc grooves extending in the up-down direction are provided inwardly on the opposite side surfaces of the outer shell 10, and the two arc grooves are provided at the intervals between the two filter element cavities d. This is equivalent to the outer shell 10 being wrapped around the outside of the middle shell 20 to achieve the above purpose, and the shape of the water pump shell 41 is similar to that of the outer shell 10. It can be said that the cross-sections of the two are arranged in an 8-shape, so it is easy to assemble. In addition, arc grooves are provided on the opposite side surfaces of the outer shell 10, one of which increases the overall use strength of the outer shell 10, and the other plays an auxiliary effect on the noise reduction effect, thereby increasing the noise reduction ability of the outer shell 10.

[0125] In a specific embodiment of the present invention, referring to Fig. 22 and Fig.24 As shown, the water purification device includes: an outer shell 10; a middle shell 20, which is installed in the outer shell 10, and the middle shell 20 has a bottom plate and two filter element cavities d arranged side by side on the bottom plate; a water pump shell 41, which is located in the outer shell 10 and is connected to the middle shell 20 to form a water pump installation cavity with the bottom plate of the middle shell 20; a water pump 71, which is installed in the water pump installation cavity.

[0126] Reference Fig.26 and Fig. 27 The water pump housing 41 includes a bottom plate 41a and an annular plate 41b erected on the upper surface of the base plate, wherein the annular plate 41b has a plurality of corners in its circumferential direction, and the corners of the enclosure plate are rounded. A sound-absorbing layer is provided on the inner surface of the annular plate 41b.

[0127] Reference Fig.26 and Fig. 27The water pump 71 is connected to a waterway plate 72; a clearance gap a is provided on one side of the annular plate 41b, and the waterway plate 72 is placed at the clearance gap a. The annular plate 41b is provided with a first inspection port b for exposing the water inlet and outlet of the water pump 71. The annular plate 41b is provided with a second inspection port c for exposing the connection port between the water pump 71 and the waterway plate 72.

[0128] The water pump housing 41 further includes a first cover plate (not shown), which covers the clearance notch a of the enclosure plate and is detachably connected to the annular plate 41b. The water pump housing 41 further includes a second cover plate (not shown), which covers the first detection port b and is detachably connected to the annular plate 41b; and / or the water pump housing 41 further includes a third cover plate (not shown), which covers the second detection port c and is detachably connected to the annular plate 41b.

[0129] The housing 10 is a shell having upper and lower openings, an upper cover (not shown) covering the upper opening of the shell, and a base 40 covering the lower opening of the shell; the shell is cylindrical.

[0130] The two opposite side surfaces of the shell are inwardly concavely provided with arc grooves extending in the up-down direction, and the two arc grooves are arranged at the intervals corresponding to the two filter element cavities d.

[0131] Reference Figure 22-29 A water purification device 1000 according to other embodiments of the present invention is described.

[0132] The present invention provides a water purification device 1000, which is a device such as a water purifier or a water purifier. The water pump of the water inlet is installed through a base 40 in a housing, so that the noise propagation of the water pump is blocked in a small installation cavity of the base 40, and at the same time, the base 40 and the housing are used to perform double-layer noise isolation to effectively reduce the noise radiation of the water pump, thereby achieving a good noise reduction effect.

[0133] See also Figure 22 to Figure 24The present invention proposes a water purification device 1000, which includes a shell 10, and the shape of the shell 10 is set according to different needs. In the present application, the shell 10 includes a cylindrical shell 10, an upper cover (not shown) provided at the upper and lower ends of the shell 10, and a base 40, whereby the shell 10, the upper cover and the base 40 are assembled to form an accommodating space. Among them, the cross-section of the shell 10 is arranged in an 8-shaped shape, that is, the two side panels with a longer width of the shell 10 are concave with arc grooves extending up and down, and the setting of the arc groove is first to strengthen the strength of the shell 10, and secondly, to form a plurality of arc transitions on the inner surface of the shell 10 to achieve a better noise reduction effect. In addition, a middle shell 20 is installed in the accommodating space of the shell 10, and a filter element is installed in the middle shell 20, and then the filter element filters the incoming water.

[0134] Specifically for the middle shell 20, a filter cartridge cavity d is provided on the middle shell 20, and the filter cartridge cavity d may be provided with one or more. When multiple filter cartridge cavities d are provided, the arrangement of the multiple filter cartridge cavities d may be determined according to different requirements. In the present application, two filter cartridge cavities d are provided on the middle shell 20, and the two filter cartridge cavities d extend in the up-down direction and are arranged side by side, so that the arc groove on the outer shell 10 corresponds to the interval between the two filter cartridge cavities d, so as to cooperate with the above-mentioned outer shell 10 to make the assembly more compact.

[0135] The lower end of the middle shell 20 is installed with a water pump shell 41, and the water pump shell 41 and the bottom plate of the middle shell 20 are enclosed to form an installation cavity, and the water pump 71 is installed in the installation cavity. It is easy to understand that the water pump shell 41 is installed at the bottom of the middle shell 20, and then the water pump 71 is installed in the water pump shell 41. First, because the accommodation space formed is small, when the water pump 71 is installed in the water pump shell 41, the propagation resistance of the noise generated by the water pump 71 in the small space is large, and the sound wave itself will interfere, so the noise reduction effect can be initially achieved; second, because the water pump shell 41 is installed in the outer shell 10, and the water pump 71 is installed in the water pump shell 41, the noise generated by the water pump 71 is hindered by the double shell plate (water pump shell 41 and outer shell 10), which greatly increases the propagation resistance of the noise, thereby achieving an excellent noise reduction effect. It is also worth mentioning that the shape of the water pump housing 41 can be set according to different requirements. In this embodiment, in order to match the shape of the housing 10, it is preferred to set the cross-sectional shape of the water pump housing 41 to correspond to the housing 10. The connection between the water pump housing 41 and the middle housing 20 can be a fixed connection or a detachable connection, such as welding, bonding, plugging, clamping, screw connection or bolt connection.

[0136] The technical solution of the present invention is to set a water pump housing 41 at the bottom of the middle shell 20, and the water pump housing 41 is located in the outer shell 10, and then install the water pump 71 in the water pump housing 41. Therefore, during the operation of the water pump 71, the noise generated is initially blocked by the small space of the water pump housing 41, so as to increase the propagation resistance of the noise. At the same time, part of the noise that passes through the water pump housing 41 is again blocked by the outer shell 10 during the propagation process, which further reduces the propagation of the noise. Therefore, under the double-layer noise blocking effect of the water pump housing 41 and the outer shell 10, the noise generated by the operation of the water pump 71 is isolated, so as to achieve an excellent noise reduction effect.

[0137] For further information, see Fig.25 and Fig.26 The water pump housing 41 includes a bottom plate 41a and an annular plate 41b erected on the upper surface of the bottom plate 41a, wherein the annular plate 41b has a plurality of corners in its circumferential direction, and the corners of the annular plate 41b are chamfered. It is easy to understand that the corners of the annular plate 41b are chamfered, which can achieve a better silencing effect than the case of a straight corner setting.

[0138] In another embodiment, in order to achieve a better sound-absorbing effect, a sound-absorbing layer is provided on the inner surface of the annular plate 41b. Therefore, the sound-absorbing layer provided can absorb the noise generated by the water pump 71 to achieve a better noise reduction effect. Among them, the sound-absorbing layer can be a sound-absorbing cotton setting or a perforated plate setting; the perforated plate is explained, and the perforated plate is a microporous plate setting, that is, a plurality of sound-absorbing holes are provided on the plate body, and the aperture of the sound-absorbing hole and the hole spacing between each sound-absorbing hole are specifically determined according to the wavelength of the noise generated by the water pump 71. It is also worth mentioning that the perforated plate can be formed by opening a sound-absorbing hole on the bottom plate 41a of the water pump housing 41, or it can be a perforated plate separately provided inside the water pump housing 41. Compared with the latter, the separately provided perforated plate and the annular plate 41b are spaced to form a double-layer sound insulation plate setting, so it can achieve a better sound-absorbing effect.

[0139] In another embodiment, see Fig. 22 and Fig.23 Since the water pump 71 is connected to the waterway plate 72, and the waterway plate 72 is installed with components such as the pressure switch 73, when the water pump 71 is installed on the water pump housing 41, the water pump housing 41 will interfere with the installation of the waterway plate 72 and the pressure switch 73, thereby affecting the installation of the waterway plate 72 and the pressure switch 73. Furthermore, in this embodiment, a clearance gap a is provided on one side of the annular plate 41b corresponding to the waterway plate 72, so that the waterway plate 72 and the pressure switch 73 can be placed in the clearance gap a for installation.

[0140] Furthermore, in order to reduce the influence of the opening of the clearance gap a on the overall noise reduction effect of the water pump housing 41, in another preferred embodiment, the water pump housing 41 is provided with a first cover plate (not shown in the figure), which covers the clearance gap a of the annular plate 41b and is detachably connected to the annular plate 41b. It is easy to understand that since the original parts such as the waterway plate 72 are placed at the clearance gap a, when the first cover plate covers the clearance gap a, the first cover plate itself has a certain accommodation position for accommodating the waterway plate 72 and other components, for example, the cover accommodation space is formed by the depression of the plate surface of the first cover plate, or the first cover plate is set with a certain curvature, so it can be surrounded at the clearance gap a to block the clearance gap a.

[0141] Before using the water purification device 1000, the air tightness of the water purification device 1000 is generally tested to prevent water leakage during use of the water purification device 1000. The general testing method is to fill the water pump 71 and each water path with test gas, and then use a test probe to approach the water inlet and outlet of the water pump 71 (such as Fig.23 As shown, the adjacent water inlet is set), and the connection port connecting the waterway plate 72 is tested to see if there is any air leakage. In this regard, based on the above embodiment, since the water pump housing 41 and the middle housing 20 cooperate to form a closed cavity for placing the water pump 71, when the inspector tests the air tightness of the water purification equipment 1000, it is necessary to open the water pump housing 41 and then move the monitoring head close to the flow path structure of the water pump 71, which is more troublesome. Therefore, please refer to Fig.25 and Fig.26 In this embodiment, a first inspection port b is provided on the annular plate 41b for exposing the water inlet and the water outlet e of the water pump 71. When the inspector needs to inspect the water inlet and the water outlet e of the water pump 71, the inspector can directly insert the inspection head into the first inspection port b for inspection. Furthermore, in order to facilitate the inspector to perform air tightness inspection on the connection port between the water pump 71 and the waterway plate 72, a second inspection port c is provided on the annular plate 41b for exposing the connection port between the water pump 71 and the waterway plate 72. Therefore, when the inspector needs to inspect the connection port between the water pump 71 and the waterway plate 72, the inspector can directly insert the inspection head into the second inspection port c for inspection.

[0142] Further, refer to Fig.25 and Fig.26, since the opening of the first inspection port b and the second inspection port c will affect the noise reduction ability of the water pump housing 41. Therefore, in another embodiment, the water pump housing 41 is provided to further include a second cover plate (not shown in the figure), the second cover plate covers the first inspection port b, and is detachably connected to the annular plate 41b; and / or the water pump housing 41 further includes a third cover plate, the third cover plate covers the second inspection port c, and is detachably connected to the annular plate 41b. Preferably, the first inspection port b and the second inspection port c are both covered by a cover plate, so when it is necessary to conduct an air tightness test on the water purification equipment 1000, the second cover plate and the third cover plate are first removed to expose the area to be tested. After the test is completed, the second cover plate and the third cover plate are respectively closed corresponding to the first inspection port b and the second inspection port c, thereby avoiding the opening of the inspection port affecting the noise reduction effect of the water pump housing 41.

[0143] There are many ways to disassemble and connect the second cover plate and the third cover plate, so they are not described in detail. And the disassembly methods are common knowledge in the field, so the disassembly methods that are easy to think of or obtained by reasonable reasoning by those skilled in the art are within the protection scope of this application.

[0144] Based on any of the above embodiments, the housing assembly 100 of the water purification device 1000 is further described. Fig. 22 The shell assembly 100 includes a shell 10 with upper and lower openings, an upper cover covering the upper opening of the shell 10, and a base 40 covering the lower opening of the shell 10; wherein the shell 10 is cylindrical. It should be explained that the shell 10, the upper cover and the base 40 enclose a closed cavity, the water pump shell 41 is installed in the cavity, and the water pump 71 is installed in the water pump shell 41, so that the noise generated by the water pump 71 is first blocked and reduced by the water pump shell 41, and then blocked by the shell 10, thereby reducing the working noise of the water purification equipment 1000. It should also be explained that the shell 10 is cylindrical, which can be understood as the surface of the shell 10 is smoothly transitioned in its circumferential direction, that is, each corner in the circumferential direction is rounded, so it can achieve a better sound-absorbing effect.

[0145] Furthermore, in order to make the overall assembly of the water purification equipment 1000 more compact and reduce the overall volume. Therefore, in this embodiment, arc grooves extending in the up-down direction are provided inwardly on the opposite side surfaces of the outer shell 10, and the two arc grooves are provided at the intervals between the two filter element cavities d. This is equivalent to the outer shell 10 being wrapped around the outside of the middle shell 20 to achieve the above purpose, and the shape of the water pump shell 41 is similar to that of the outer shell 10. It can be said that the cross-sections of the two are arranged in an 8-shape, so it is easy to assemble. In addition, arc grooves are provided on the opposite side surfaces of the outer shell 10, one of which can increase the overall use strength of the outer shell 10, and the other has an auxiliary effect on the noise reduction effect, thereby increasing the noise reduction ability of the outer shell 10.

[0146] In a specific embodiment of the present invention, referring to Figure 22-Figure 29 The water purification device 1000 comprises: a housing 10 having a vertical direction; a middle housing 20 vertically mounted in the housing 10, the middle housing 20 having two filter element chambers d arranged side by side in a transverse direction; and a water pump 71 transversely mounted at one end of the middle housing 20 in a vertical direction. Preferably, the water pump 71 is mounted below the middle housing 20.

[0147] Preferably, the water purification device 1000 further includes a water pump housing 41, which is installed at the lower end of the middle frame to enclose with the middle shell 20 to form an installation cavity, and the water pump 71 is installed in the installation cavity.

[0148] Preferably, a mounting seat 74 is connected to the lower part of the water pump 71, and the water pump 71 is mounted on the water pump housing 41 through the mounting seat 74. Preferably, a plurality of shockproof support pads 75 are provided on the mounting seat 74, and the plurality of shockproof support pads 75 support the mounting seat 74.

[0149] Preferably, a drainage hole is formed on the bottom surface of the water pump housing 41. Preferably, the water pump is connected to a waterway plate 72; the water pump housing 41 includes a bottom plate 41a, and an annular plate 41b erected along the periphery of the bottom plate 41a, a clearance gap a is formed on one side of the annular plate 41b, and the waterway plate 72 is placed at the clearance gap a.

[0150] Preferably, the annular plate 41b is provided with a first inspection port b for exposing the water inlet and outlet of the water pump 71; and / or the annular plate 41b is provided with a second inspection port c for exposing the connection port between the water pump 71 and the waterway plate 72.

[0151] Preferably, the housing 10 is a shell with upper and lower openings, an upper cover covering the upper opening of the shell, and a base 40 covering the lower opening of the shell; wherein the shell is cylindrical. Preferably, two opposite sides of the shell are concavely provided with arc grooves extending in the up-down direction, and the two arc grooves are provided at the intervals between the two filter element cavities.

[0152] Reference Fig. 22 , Figure 27-Figure 34 A water purification device 1000 according to other embodiments of the present invention is described.

[0153] The present invention provides a water purification device 1000, which is a device such as a water purifier or a water purifier. The water pump power line of the water purification device 1000 is routed through a cable tie groove on a bottom plate 41a of a water pump housing 41, thereby improving the fixing strength of the water pump power line and preventing it from being pulled away from the water pump.

[0154] The present invention discloses a water purification device 1000, please refer to Fig. 22 , the water purification equipment 1000 includes a shell 10, and the shape of the shell 10 is specifically set according to different needs. In the present application, the shell 10 includes a cylindrical shell 10 with upper and lower openings, an upper cover (not shown) provided on the shell 10 and the base 40 provided on the lower opening of the shell 10, so that the shell 10, the base 40 and the upper cover are assembled to form an accommodating space. Among them, the cross-section of the shell 10 is arranged in an 8-shaped shape, that is, the two side panels with a longer width of the shell 10 are concave with arc grooves. The setting of the arc groove is first to strengthen the strength of the shell 10, and secondly, to form a plurality of arc surface transitions on the inner surface of the shell 10 to achieve a better noise reduction effect. In addition, a middle shell 20 is installed in the accommodating space of the shell 10, and a filter element is installed in the middle shell 20, and the filter element filters the incoming water.

[0155] Specifically, for the middle shell 20, a filter cartridge cavity d is provided on the middle shell 20, and the filter cartridge cavity d may be provided with one or more. When multiple filter cartridge cavities d are provided, the arrangement of the multiple filter cartridge cavities d may be determined according to different requirements. In the present application, two filter cartridge cavities d are provided on the middle shell 20, and the two filter cartridge cavities d extend in the up-down direction and are arranged side by side, thereby, the corresponding outer shell 10 can be matched more compactly.

[0156] In addition, a water pump housing 41 is installed at the lower end of the middle shell 20, and the water pump housing 41 is located between the middle shell 20 and the base 40. The water pump housing 41 and the middle shell 20 enclose an installation cavity, and a water pump is installed in the installation cavity, which is equivalent to enclosing the water pump in a smaller space to reduce the noise propagation of the water pump. The water pump housing 41 includes a bottom plate 41a, and an annular plate 41b erected along the periphery of the bottom plate 41a, and the annular plate 41b is fixed to the middle shell 20, wherein the fixing method is preferably a detachable fixing method, such as screws, clamping, clamping or bonding. The outer side surface of the annular plate 41b is provided with a wiring groove, and the bottom surface of the bottom plate 41a is provided with a cable tie groove 410, and then the power cord of the water pump 71 passes through the wiring groove of the annular plate 41b to the cable tie groove 410 for position fixing and then passes through the outer shell 10.

[0157] For a detailed description of the cable trough 410, please refer to Fig. 27 and Fig.28 , the wire harness groove is arranged on the bottom surface of the base 40, and the wire harness groove can be directly formed by the convex arrangement of the bottom surface of the water pump housing 41, or it can be a groove body separately arranged on the bottom surface of the water pump housing 41. Among them, in order to play the role of wiring, to prevent the wires from being easily pulled after being installed in the wiring harness groove 410, because the wiring harness groove 410 is arranged in a bent setting, the wiring harness groove 410 has at least one bend, and then the wiring harness groove 410 increases the sliding resistance of the wire through the bend to achieve the wiring harness effect. Of course, in order to achieve a better wiring harness effect, it is preferred to set the wiring harness groove 410 to have multiple bends. It is also worth mentioning that in order to protect the water pump wires and prevent them from being squeezed and damaged by the sharp corners of the wiring harness groove 410 during the process of circling the wiring harness groove 410, it is preferred that the bend of the wiring harness groove 410 has a rounded transition.

[0158] During the specific winding process, the power cord of the water pump 71 extends out from the water pump housing 41, and then goes down through the wiring groove on the annular plate 41b of the water pump housing 41. It is worth mentioning here that the wire inlet M of the wire trough 410 is opposite to the wire outlet N of the wire trough. Therefore, after the water pump wire is routed downward from the wire trough to the wire trough 410, it is wound and fixed through the wire trough 410, and then passes through the outer casing 10 from the wire outlet N of the wire trough 410 to be connected to an external power source.

[0159] It is also worth mentioning that, since the water pump housing 41 of the present application is located inside the housing 10, that is, there is a base 40 below the water pump housing 41 for covering, the water pump housing 41 is concealed. Therefore, compared with the water pump power cord of the existing water purification device 1000 fixed at the bottom of the housing 10, it is effectively prevented that the water pump power cord is scratched by external objects during use or transportation of the water purification device 1000, thereby interfering with or damaging the water pump power cord.

[0160] The technical solution of the present invention is to provide a water pump housing 41 at the lower end of the middle shell 20, and then the water pump housing 41 and the middle shell 20 enclose an installation cavity for the water pump to be installed, which is equivalent to enclosing the water pump in a smaller space to reduce the noise propagation of the water pump. In addition, a cable trough 410 is provided on the bottom surface of the water pump housing 41, and the cable trough 410 is bent, so when the water pump power line passes through the cable trough 410 and then extends out of the outer shell 10, even if the water pump power line is subjected to external tension, it is difficult to slide and cause the connection between the water pump power line and the water pump to be detached.

[0161] On the basis of the above-mentioned embodiment, the cable trough 410 is bent. If the bending angle of the cable trough 410 is large, the cable bundling effect of the trough is poor. If the bending angle of the cable trough 410 is small, the water pump wire is easily damaged during the detour. Therefore, preferably, the bending angle of the bending part of the cable trough 410 is set to 85°~125°, for example, the bending angle is: 85°, 90°, 95°, 100°, 105°, 110°, 115° or 120°, etc. Of course, it is worth mentioning that since the cable trough 410 is preferably provided with multiple bending parts in the present application, it can be understood that the bending angle of each bending part is preferably within the above-mentioned value range.

[0162] It is also worth mentioning that in order to protect the water pump wires and prevent them from being squeezed and damaged by the sharp corners of the wire harness trough 410 during the process of routing the wire harness trough 410, it is preferred that the bends of the wire harness trough 410 have rounded transitions.

[0163] In a preferred embodiment, the cable trough 410 includes a first trough section 411, a second trough section 412, a third trough section 413 and a fourth trough section 414 connected in sequence, and a bend of the cable trough 410 is formed by an angle between each trough section. In the present application, the angle between each trough section is particularly set to 90°. However, it should be noted that the connection angle between the first trough section 411, the second trough section 412 and the third trough section 413 connected in sequence is 90°, wherein the first trough section 411 and the third trough section 413 can be located on the same side of the second trough section 412, or can be located on opposite sides of the second trough section 412. Similarly, the connection angle between the second trough section 412, the third trough section 413 and the fourth trough section 414 connected in sequence is 90°, at which time the second trough section 412 and the fourth trough section 414 can be located on the same side of the third trough section 413, or can be located on opposite sides of the second trough section 412. Considering that, in order to achieve a better beam-binding effect, in this embodiment, please refer to Fig.28Preferably, the first slot section 411 and the third slot section 413 extend toward the opposite sides of the second slot section 412 respectively, and the second slot section 412 and the fourth slot section 414 extend toward the opposite sides of the third slot section 413 respectively, so as to achieve the above-mentioned better wiring bundling effect.

[0164] It is also worth mentioning that in order to protect the water pump wires and prevent them from being squeezed and damaged by the sharp corners of the wire harness trough 410 during the process of routing the wire harness trough 410, it is preferred that the angles between the groove sections are chamfered.

[0165] In another embodiment, please continue to refer to Fig.28 , the outlet N of the cable trough 410 is configured as a constricted opening. It is easy to understand that the outlet N of the cable trough 410 is configured as a constricted opening, so that when the water pump power cord is installed in the cable trough 410, the notch of the cable trough 410 can clamp the water pump power cord, and then during the use of the water purification device 1000, the water pump power cord is not easily pulled or loosened. Of course, it is also preferred to set the inlet M of the cable trough 410 to be a constricted opening to further enhance the fixing strength of the water pump power cord.

[0166] In yet another embodiment, see Fig.29 and Fig.30 , a first wire clamping structure 420 is provided on the groove wall of the cable trough 410, and the first wire clamping structure 420 is located in the outlet N of the cable trough 410. It is easy to understand that for the same reason as the previous embodiment, in order to enhance the fixing strength of the water pump power cord, it is not easy to be pulled or loosened. Therefore, in this embodiment, a first wire clamping structure 420 is provided at the outlet N of the cable trough 410, so the water pump power cord installed at the outlet N of the cable trough 410 is clamped and fixed by the first wire clamping structure 420. Of course, the first wire clamping structure 420 can also be provided in the inlet of the cable trough 410 at the same time, thereby further enhancing the fixing strength of the water pump power cord. Among them, there are many ways to set the first wire clamping structure 420, for example: a clamping point protruding inward from the groove wall of the cable trough 410; or a glue point coated on the groove wall of the cable trough 410; or a clamp bonded to the groove wall of the cable trough 410, etc. In this embodiment, the first wire clamping structure 420 is preferably provided as a glue point on the groove wall.

[0167] Further, on the basis of the previous embodiment, a plurality of second wire clamping structures 430 are also provided on the groove wall of the cable trough 410, and the plurality of second wire clamping structures 430 are spaced apart in the cable trough 410. It is easy to understand that a plurality of spaced apart second wire clamping structures 430 are also provided on the groove wall of the cable trough 410, so when the water pump power cord is placed in the cable trough 410, the part of the wire body accommodated in the cable trough 410 can be clamped by the cooperation of the first wire clamping structure 420 and the second clamping, thereby not only preventing the water pump power cord from being easily pulled, but also preventing the water pump power cord from slipping out of the cable trough 410. Among them, the setting method of the second wire clamping structure 430 can also refer to the setting method of the first wire clamping structure 420. In this embodiment, the second wire clamping structure 430 is preferably a glue point coated on the groove wall of the cable trough 410.

[0168] In another embodiment, see Fig.31 and Fig.32 , a rubber strip 440 is provided on at least one groove wall of the cable trough 410, and the rubber strip 440 is fixed to the groove wall of the cable trough 410 and extends along the extension of the cable trough 410. It is easy to understand that the rubber strip 440 is provided on the groove wall of the cable trough 410, so when the water pump power cord is accommodated in the cable trough 410, the rubber strip 440 protruding from the groove wall of the cable trough 410 clamps the water pump power cord to enhance the fixing strength of the water pump power cord. Among them, the setting mode of the rubber strip 440 can be a continuous rubber strip 440, or it can be an intermittently set rubber strip 440. In addition, the rubber strip 440 can be provided on one side groove wall of the cable trough 410, or the rubber strip 440 can be provided on both groove walls of the cable trough 410.

[0169] In yet another embodiment, see Fig.33 and Fig.34 The cable trough 410 has a notch opposite to the bottom of the trough, and the edge of the notch protrudes inwardly with a limiting protrusion 450. Specifically, the limiting protrusion 450 is formed by the edge of the notch protruding inwardly, and the thickness of the limiting protrusion 450 is small so as to have a certain deformation capacity. Therefore, when the water pump power cord is placed in the cable trough 410, the water pump power cord first presses the limiting protrusion 450 to bend and deform toward the bottom of the trough, and then when the water pump power cord is accommodated in the cable trough 410, the limiting protrusion 450 returns to its original state to limit the water pump power cord in the cable trough 410 to prevent it from falling out.

[0170] Based on any of the above embodiments, please refer to Fig.29 , Fig.31 and Fig.33, the bottom surface of the base 40 is also provided with a wire fixing structure 460, and the wire fixing structure 460 is provided adjacent to the wire outlet N. It is easy to understand that since the external power line of the water pump power line extending from the wire outlet N of the wire trough 410 is outside the housing 10, when the part of the wire body extending outside the housing 10 is subjected to tension, the water pump power line will be pulled out of the wire outlet N of the wire trough 410, causing the wires in the entire wire trough 410 to be detached. Therefore, in this embodiment, the wire outlet N adjacent to the wire trough 410 is provided with a wire fixing structure 460, and the wire body at the wire outlet N of the wire trough 410 is fixed to avoid the above-mentioned problem.

[0171] There are many ways to set the wire fixing structure 460, as long as the water pump power line can be fixed. Specifically in the embodiment, the wire fixing structure 460 includes a wire fixing plate, the opposite ends of the wire fixing plate are fixed to the surface of the water pump housing 41, and the plate body of the wire fixing plate and the surface of the water pump housing 41 are surrounded to form a wire fixing through hole. The wire fixing plate and the water pump housing 41 are detachably connected, and in this embodiment, a screw connection is adopted, and then when fixing the wire, it is only necessary to press the wire fixing plate onto the water pump power line, and then fix the two ends with screws.
