However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0029] See Figures 1-9 A top cover detachable structure for a water purifier, the water purifier including a body 1 and a top cover 2 detachably installed on the body 1, the top of the body 1 is provided with an upwardly protruding connector, the connector cooperates with the inner side of the top cover 2, and the connector is provided with a fixing part for fixing the top cover 2. When the top cover 2 is installed, the inner side of the top cover 2 abuts against the connector, and the top cover 2 moves axially along the connector to a position that matches the fixing part, thereby achieving a fixed connection between the top cover 2 and the body 1. When the top cover 2 is removed, move the top cover 2 in the direction of the connector separating from the fixing part. After the top cover 2 is completely separated from the fixing part, the separation between the top cover 2 and the body 1 is achieved.

[0030] In the top cover disassembly and assembly structure of this water purifier, the top of the body 1 has an upwardly protruding connector that mates with the inner side of the top cover 2. The connector also has a fixing part for securing the top cover 2, eliminating the need for additional screws or other fasteners between the body 1 and the top cover 2. This effectively reduces the number of parts and eliminates the need for screwdrivers or other tools during installation, facilitating the removal and installation of the top cover 2 from the top of the body 1.

[0031] The entire top cover 2 and its internal structure can be manufactured using a one-piece molding process. The one-piece molding design eliminates the need for subsequent machining of screw holes and complex processes such as splicing multiple parts, significantly reducing the number of processing steps and simplifying production.

[0032] Compared with the complex multi-part structure of the CN219823728U patent in the background technology, this structure achieves fixation through the cooperation of the connector and the fixing part, without additional fasteners and the top cover 2 is integrally formed, which makes it easier to process and manufacture, has higher production efficiency, and has significant cost advantages. It is more suitable for large-scale mass production, while also providing users with a more convenient and reliable disassembly and assembly experience, effectively meeting the market's demand for low-cost and easy-to-maintain water purifiers.

[0033] The connector includes a first connecting block 101 and a second connecting block 102 disposed on the left and right sides of the top of the body 1. The first connecting block 101 protrudes vertically from the top of the body 1, and the second connecting block 102 is disposed horizontally on the top of the first connecting block 101. A first fixing groove 103 of the fixing part is formed between the first connecting block 101, the second connecting block 102 and the top of the body 1. The top cover 2 is provided with a guide block 201 that cooperates with the first fixing groove 103 on the inner side. The top cover 2 is installed on the body 1. The guide block 201 of the top cover 2 is inserted into the first fixing groove 103 along the second connecting block 102. The guide block 201 of the top cover 2 is limited between the second connecting block 102 and the top of the body 1. The second connecting block 102 forms an anti-detachment part to prevent the top cover 2 from detaching from the body 1.

[0034] The first connecting block 101, the second connecting block 102, and the top of the body 1 form a first fixing groove 103 for fixing. A guide block 201 on the inner side of the top cover 2 engages with the first fixing groove 103. The entire fixing process requires no additional screws or other fasteners. Eliminating screws not only reduces component procurement costs but also avoids the tedious screw assembly process during production. There is no need to machine screw holes between the body 1 and the top cover 2, nor is it necessary to manually or mechanically tighten screws, significantly improving production assembly efficiency and reducing labor and equipment investment costs.

[0035] From a manufacturing perspective, the guide block 201 can be integrally formed with the top cover 2. This integral forming process creates a complete structure between the top cover 2 and the guide block 201, eliminating the need for separate processing of the guide block 201 before assembly (such as welding or bonding). This reduces processing steps and assembly processes, lowering manufacturing complexity. Furthermore, the integral forming process avoids potential issues like weak connections or excessive gaps that may occur during assembly, improving the stability of the connection between the guide block 201 and the top cover 2. This ensures that the guide block 201 is less likely to detach or be damaged during insertion or removal from the first fixing groove 103 along the second connecting block 102, extending the service life of the top cover 2.

[0036] The first connecting block 101 and the second connecting block 102 are provided with a vertically arranged first limiting block 104 at their ends. When the top cover 2 is installed in place, one end of the guide block 201 abuts against the first limiting block 104.

[0037] When the top cover 2 is slidably installed on the top of the body 1, the inner side of the top cover 2 abuts against the corresponding connecting piece, and the guide block 201 slides to the first fixing groove 103. When one end of the guide block 201 abuts against the first limiting block 104, the top cover 2 can no longer slide, that is, the top cover 2 is installed in place.

[0038] The top cover 2 has a guide block 201 with a second limiting block 202 at one end. The second limiting block 202 is vertically arranged on the inner side of the top cover 2. When the top cover 2 is installed in place, the second limiting block 202 abuts against the second connecting block 102.

[0039] When the top cover 2 is slidably installed on the top of the body 1, the inner side of the top cover 2 abuts against the corresponding connecting piece, and the guide block 201 slides to the first fixing groove 103. When the second limiting block 202 abuts against the second connecting block 102, the top cover 2 can no longer slide, that is, the top cover 2 is installed in place.

[0040] The left and right sides of the body 1 are provided with several sets of first connecting blocks 101 and second connecting blocks 102, and each set of first connecting blocks 101 and second connecting blocks 102 is arranged at intervals along the front and rear direction of the body 1. The connector also includes a third connecting block 105 disposed on the top of the body 1, and the third connecting block 105 is connected to one of the first connecting blocks 101 and the second connecting block 102; The inner side of the top cover 2 is provided with an inner flange 203 for abutting against the third connecting block 105.

[0041] The cooperation between the third connecting block 105 and the inner flange 203 effectively increases the guiding area of ​​the top cover 2 for disassembly and assembly, so that the top cover 2 is not prone to displacement during disassembly and assembly, and the top cover 2 can be slidably disassembled and assembled on the top of the body 1 along the set path.

[0042] The connector includes a fourth connecting block 106 located on the front and rear sides of the top of the body 1. The fourth connecting block 106 is provided with a fastening slot 107 forming a fixing part. The inner side of the top cover 2 is provided with a fastening block 204 that cooperates with the fastening slot 107.

[0043] The fourth connecting block 106 extends laterally and is disposed on the inner side of the top cover 2.

[0044] The third connecting block 105 is provided with a guide slope 109 for guiding the installation or detachment of the top cover 2 from the body 1.

[0045] When the top cover 2 is installed, the bottom of the guide block 201 of the top cover 2 can abut against the top of the third connecting block 105. When the top cover 2 slides, the guide block 201 slides into the first fixing groove 103 along the guide slope 109. When the guide block 201 cannot move, the fastening block 204 is just inserted into the fastening groove hole 107. At this time, the fixed installation between the top cover 2 and the body 1 is completed.

[0046] The top cover 2 is detachable. Under the action of external force, the top cover 2 slides. The fastening block 204 on the front side of the top cover 2 first disengages from the fastening slot 107 on the front side of the body 1. At the same time, as the top cover 2 continues to slide, the guide block 201 disengages from the first fixing slot 103 in sequence. When the bottom of the guide block 201 gradually slides along the guide slope 109 to the top of the third connecting block 105, the fastening block 204 on the rear side of the top cover 2 disengages from the fastening slot 107 on the rear side of the body 1. At this time, the disassembly between the top cover 2 and the body 1 is completed.

[0047] The inner side of the top cover 2 is provided with reinforcing ribs 205 to increase the structural strength of the top cover 2.
