Detailed implementation manner

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0036] Refer to Figures 1-5 , the present invention discloses a pre-filter scale inhibitor, including an outer shell a 100 and an outer shell b 200. After the outer shell a 100 and the outer shell b 200 are connected, a complete water treatment chamber is formed. The outer shell a 100 and the outer shell b 200 are connected by a quick-release part 300. The outer shell a 100 is provided with a purified water outlet 101, and a protective cap 102 is covered on the finished purified water outlet 101. The outer shell b 200 is provided with a water inlet 201, and the water source to be roughly filtered enters the water treatment chamber from the water inlet 201 and is discharged through the purified water outlet 101. An inner core assembly 500 is arranged inside the water treatment chamber, and the water is roughly filtered through the inner core assembly 500.

[0037] Refer to Figure 1 , in order to solve the connection stability between the outer shell a 100 and the outer shell b 200, and to facilitate the daily maintenance of the inner core assembly 500, this embodiment discloses a quick-release part 300, combined with Figures 2-5 , Figure 7Describe its disassembly and assembly principle in detail. The quick-release part 300 includes a hoop 301 and a positioning member 302. The positioning member 302 is used to connect between the outer shell a100 and the outer shell b200. The hoop 301 is sleeved on the positioning member 302 to apply a locking force to it, so that the outer shell a100 and the outer shell b200 are tightly connected.

[0038] Furthermore, the connecting edge between the outer shell a100 and the outer shell b200 is designed with an arc-shaped fit. This structural design can cooperate with the positioning member 302 to achieve the anti-disconnection effect between the outer shell a100 and the outer shell b200. Specifically, the opening edge of the outer shell a100 expands outward integrally to form an outward-expanded edge 103. Both sides of the outward-expanded edge 103 are arc-shaped surfaces. The opening edge of the outer shell b200 contracts inward integrally to form an inward-contracted edge 203. A raised edge 202 is provided at the junction of the inward-contracted edge 203 and the outer shell b200. When the outer shell b200 covers the opening of the outer shell a100, the inward-contracted edge 203 is embedded inside the outward-expanded edge 103 and fits together. The raised edge 202 abuts against the end of the outward-expanded edge 103. The positioning member 302 is sleeved on the outward-expanded edge 103 and the raised edge 202, thereby restricting the separation between the raised edge 202 and the outward-expanded edge 103;

[0039] It should be noted that the inward-contracted edge 203 and the outward-expanded edge 103 need to be sealed, such as using a gasket, etc.

[0040] Refer to Figure 3 , which discloses a specific implementation manner of the positioning member 302. It mainly consists of an elastic positioning ring 3021. A notch 3022 is provided on the positioning ring 3021, which is convenient for sleeving on the outward-expanded edge 103. The inner side of the positioning ring 3021 fits with the outer side edge of the outward-expanded edge 103. In order to achieve the technical effect of anti-dropping, a raised surface 3023 matching the outer surface of the outward-expanded edge 103 is formed on the inner side of the positioning ring 3021. An inner groove 3024 is formed by the transition at the upper end of the raised surface 3023. The inner groove 3024 is mainly used to accommodate the raised edge 202. Then, the raised edge 202 on the outer shell b200 is snapped into the inner groove 3024 for positioning, and the outward-expanded edge 103 of the outer shell a100 is positioned through the raised surface 3023. After the hoop 301 locks the positioning ring 3021, the tight fit between the outer shell a100 and the outer shell b200 is achieved.

[0041] Similarly, with Figure 3Taking this as an example, the structural composition of the hoop 301 will be described in detail. The hoop 301 in this embodiment includes a base 3011 and a metal strip 3012 connected to the base 3011. The metal strip 3012 can be made of a flexible material, such as a steel sheet or other metal materials with high toughness. A plurality of equally spaced driving grooves 3014 are formed on the metal strip 3012, and a screw 3013 cooperating with the driving grooves 3014 is provided on the base 3011. The shape of the driving grooves 3014 is the same as the tooth shape of the screw 3013. In this embodiment, the tooth shape of the screw 3013 is preferably rectangular, so as to have high self-locking property.

[0042] Referring to Figure 2 , Figure 4 , Figures 6-8 , the inner core assembly 500 includes a first partition 501 and a second partition 502. The first partition 501 and the second partition 502 are hermetically connected to the inner wall of the outer shell a100. One or more mandrels 503 are provided between the first partition 501 and the second partition 502. The mandrels 503 are preferably cylindrical, with a quantity of three, and a through filtering cavity 5031 is formed inside. Both ends of the mandrel 503 are hermetically connected to the first partition 501 and the second partition 502 respectively. Among them, a first through hole 5012 is provided on the first partition 501 at the position of the filtering cavity 5031, and a filtering layer 5013 is provided on each first through hole 5012. A second through hole 5022 is formed on the second partition 502, and the second through holes 5022 are distributed on the outer periphery of the mandrel 503. Water enters the filtering cavity 5031 through the first through hole 5012, and particulate matters and the like are retained in the filtering cavity 5031. The purified water enters the outer shell a100 through the side wall of the mandrel 503, and then is discharged through the second through holes 5022 on the second partition 502.

[0043] Furthermore, the number of the second through holes 5022 is multiple, and the positions and sizes of the multiple second through holes 5022 are designed according to the number of the mandrels 503. In the blank area outside the connection between the mandrel 503 and the second partition 502, the second through holes 5022 are maximally opened, so as to improve the drainage capacity and avoid the situation of too small water flow.

[0044] Furthermore, referring to Figure 4 , Figure 7 and Figure 8 , preferably, the shapes of the outer shell a100, the outer shell b200, the first partition 501 and the second partition 502 are all of a rotational body structure. A first sealing ring 5011 is connected to the circumferential surface of the first partition 501, and a second sealing ring 5021 is connected to the circumferential surface of the second partition 502. The first sealing ring 5011 and the second sealing ring 5021 are preferably O-ring seals. A retaining ring 106 is provided on the inner wall of the outer shell a100, and the retaining ring 106 is used to limit the position of the second partition 502 in the outer shell a100. Please refer to Figures 6 to 8When the outer shell b200 is connected to the outer shell a100, the inwardly retracted edge 203 on the outer shell b200 abuts against the first partition 501, and the second partition 502 abuts against the retaining ring 106.

[0045] It should be noted that "abut" can be understood as that two components are in a fitting state. When the quick-release part 300 releases the locking, the inner core assembly 500 can be quickly taken out.

[0046] Refer to Figure 7 、 Figure 8 In order to improve the sealing performance between the inner core assembly 500 and the outer shell a100, a preferred implementation manner is disclosed in this embodiment. Specifically, an annular boss a104 and an annular boss b105 are connected to the inner wall of the outer shell a100. Taking the state where the outer shell b200 is connected to the outer shell a100 as an example, the first partition 501 is located at the central position of the annular boss a104, and the second partition 502 is located at the central position of the annular boss b105. The edges of the annular boss a104 and the annular boss b105 are transitioned to the inner wall of the outer shell a100 with an arc surface. The purpose of such a setting is to facilitate the installation and disassembly of the inner core assembly 500. By the annular boss a104 and the annular boss b105 protruding inward along the inner wall of the outer shell a100, the first sealing ring 5011 and the second sealing ring 5021 are thus squeezed, thereby improving the sealing effect.

[0047] Optionally, a bracket 400 is installed on the outer peripheral surface of the outer shell a100, and the bracket 400 is used to install the outer shell a100 at an actual use position such as a wall.

[0048] Through the design of the quick-release part 300 of the present utility model, the installation and disassembly processes are simplified, ensuring the close fitting of the outer shell a100 and the outer shell b200 during use, and effectively preventing problems such as loosening or water leakage caused by vibration or pressure changes.

[0049] Through the quick replacement of the inner core assembly 500, it is convenient for daily maintenance. By quickly disassembling the outer shell a100 and the outer shell b200, the inner core assembly 500 can be easily taken out for cleaning, replacement or repair, greatly reducing the maintenance time and cost. The design of the inner core assembly 500 enables water to smoothly pass through the filter cavity 5031, and particulate matter and other impurities are effectively intercepted in the filter cavity, while the purified water is discharged into the outer shell a100 through the side wall of the core rod 503 and then discharged through the second through hole 5022. It only needs to regularly clean the filter cavity of the core rod 503.

[0050] Through the sealed connection between the first partition 501, the second partition 502 and the inner wall of the outer shell a100, and in cooperation with the design of the annular boss a104 and the annular boss b105 protruding inward along the inner wall of the outer shell a100, the overall sealing performance is improved.

[0051] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
