[0037] Water purification devices, also known as water purifiers, are crucial components in water purification systems that filter water sources. They offer functions such as ultrafiltration, nanofiltration, and reverse osmosis filtration. They primarily utilize filter cartridges to remove solid particles and harmful chemical components from the water. However, in actual production, researchers have found that most existing water purification devices use threaded connections to install the filter cartridges onto the connector base. This threaded connection requires numerous rotations when disassembling the filter cartridge, increasing the complexity and difficulty of removal.

[0038] This utility model proposes a water purification device and equipment, aiming to solve the technical problems of the inconvenience and difficulty in disassembling filter bottles in existing water purification devices.

[0039] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 In one embodiment of this utility model, the water purification device includes a connecting seat 1 and a filter bottle 2. The connecting seat 1 includes a mounting frame 11, a seat body 12, and a valve core 13. The mounting frame 11 is provided with a locking groove 111. The seat body 12 is disposed on the mounting frame 11 and surrounds the mounting frame 11 to form a receiving cavity. The valve core 13 is disposed in the receiving cavity. The filter bottle 2 passes through the mounting frame 11 and is inserted into the valve core 13. The filter bottle 2 is provided with a locking block 21. The locking block 21 can slide into the locking groove 111 to lock the position of the filter bottle 2.

[0040] The technical solution of this utility model achieves the installation and disassembly of the filter bottle 2 by using a locking block 21 on the filter bottle 2 in conjunction with a locking groove 111 on the mounting frame 11. This simplifies the installation and disassembly process of the filter bottle 2 and reduces the difficulty of disassembling it. In this embodiment, the water purification device is installed to the installation position via the mounting frame 11, which supports the base 12, valve core 13, and filter bottle 2, providing support for each component of the water purification device. The base 12 is disposed on the mounting frame 11 and forms a receiving cavity with the mounting frame 11. The valve core 13 is disposed in the receiving cavity, and the filter bottle 2 passes through the mounting frame 11 and is inserted into the valve core 13. Furthermore, the filter bottle 2 is provided with a locking block 21, and the mounting frame 11 has a locking groove 111. The locking block 21 can slide into the locking groove 111 to lock the position of the filter bottle 2; at the same time, the locking block 21 can also slide out of the locking groove 111 to release the locking of the filter bottle 2. Specifically, when installing filter bottle 2 to connector 1, the user only needs to hold filter bottle 2 and push it to allow the locking block 21 of filter bottle 2 to slide into the locking groove 111, thus locking the position of filter bottle 2 and completing the installation of filter bottle 2. When removing filter bottle 2 from connector 1, the user only needs to hold filter bottle 2 and push it to allow the locking block 21 of filter bottle 2 to slide out of the locking groove 111, thus releasing the position lock of filter bottle 2 and completing the disassembly of filter bottle 2. This water purification device achieves the installation and disassembly of filter bottle 2 by using the cooperation of locking block 21 and locking groove 111. It only requires pushing filter bottle 2 to allow the locking block 21 of filter bottle 2 to slide into or out of the locking groove 111, which simplifies the installation and disassembly process of filter bottle 2 and reduces the difficulty of disassembling and assembling filter bottle 2. This water purification device is applied in the technical fields of water purification equipment and related fields.

[0041] Please see Figure 5 and Figure 6In one embodiment of this utility model, the locking groove 111 includes a first groove 1111 and a second groove 1112 that are interconnected. The first groove 1111 extends axially along the mounting frame 11, and the second groove 1112 extends circumferentially along the mounting frame 11. The locking block 21 can pass through the first groove 1111 and slide into the second groove 1112. In this embodiment, the mounting frame 11 has a through hole 112 for the filter bottle 2 to pass through, and the locking groove 111 is formed on the side wall of the through hole 112. Specifically, the locking groove 111 is composed of a first groove 1111 extending axially along the mounting frame 11 and a second groove 1112 extending circumferentially along the mounting frame 11. Since the axial and circumferential directions of the mounting frame 11 are perpendicular to each other, the locking groove 111 has an L-shaped structure. When installing filter bottle 2, the user simply lifts it upwards, aligning the locking block 21 of filter bottle 2 through the first groove 1111 and into the second groove 1112. Then, the user rotates filter bottle 2 until the locking block 21 is positioned in the second groove 1112, thus completing the installation. Conversely, when removing filter bottle 2, the user simply rotates it in the opposite direction until the locking block 21 aligns with the first groove 1111, then pulls filter bottle 2 downwards to remove it. During the installation and removal of filter bottle 2, the user only needs to rotate it a small angle, eliminating the need for numerous rotations, thus simplifying the process and reducing the difficulty of installation and removal. It should be noted that the angle required for installation and removal is primarily determined by the circumferential length of the second groove 1112 along the mounting bracket 11, and this angle can be 30°, 45°, etc. In a specific embodiment, to prevent the filter bottle 2 from rotating along the second groove 1112 and falling out of the first groove 1111 due to vibration or other factors, a third groove can be provided at the end of the second groove 1112 away from the first groove 1111, with the extension direction opposite to that of the first groove 1111. After the locking block 21 is placed in the second groove 1112, the user can continue to rotate the filter bottle 2 so that the locking block 21 is aligned with the third groove and falls into the third groove to lock the position of the locking block 21, thereby locking the position of the filter bottle 2 and preventing the filter bottle 2 from falling out.

[0042] Please see Figure 5 and Figure 6In one embodiment of this utility model, the sidewall of the first groove 1111 is inclined, and the bottom surface of the second groove 1112 is flat. In this embodiment, the sidewall of the first groove 1111 is an inclined slope, that is, the first groove 1111 is designed as a rhombus. This allows the user to simply insert the locking block 21 into the first groove 1111 and rotate the filter bottle 2 to drive the locking block 21 to rotate in the first groove 1111 when installing the filter bottle 2. During this process, the user does not need to lift the filter bottle 2 upwards, which reduces the difficulty of installing the filter bottle 2. Accordingly, in order to adapt to the rhomboid structure of the first groove 1111, both sides of the locking block 21 are inclined. In order to prevent the locking block 21 from sliding out of the second groove 1112, the bottom surface of the second groove 1112 can be designed as a flat surface to prevent the locking block 21 from sliding under the gravity of the filter bottle 2.

[0043] Please see Figure 5 and Figure 6 In one embodiment of this utility model, the filter bottle 2 is provided with a top block 22, the top block 22 having a top edge 221; when the locking block 21 slides into the locking groove 111, the top edge 221 abuts against the mounting bracket 11. In this embodiment, the top block 22 is used to lock the position of the filter bottle 2 to prevent the filter bottle 2 from shaking. Specifically, when the filter bottle 2 is installed to the connecting seat 1, the top edge 221 of the top block 22 abuts against the inner wall of the through hole 112 of the mounting bracket 11 to lock the position of the filter bottle 2, thereby preventing the filter bottle 2 from shaking. In one specific embodiment, the top block 22 also has an inclined abutment surface 222, which is inclined radially from the direction close to the filter bottle 2 to the direction away from the filter bottle 2. The top edge 221 is the side edge of the abutment surface 222 that is furthest from the filter bottle 2. When the filter bottle 2 is installed to the connecting seat 1, the abutment surface 222 abuts against the side edge of the opening of the first groove 1111, which can provide guidance for the rotation of the filter bottle 2 and at the same time, can prevent the filter bottle 2 from getting stuck due to the setting of the top block 22. In one specific embodiment, the top block 22 is located directly below the locking block 21.

[0044] In one embodiment of this utility model, there are multiple locking blocks 21 and locking grooves 111, with each locking block 21 corresponding to one of the multiple locking grooves 111. In this embodiment, the position of the filter bottle 2 is locked by the cooperation of multiple locking blocks 21 and multiple locking grooves 111, which can improve the reliability of the filter bottle 2 being installed on the connecting seat 1. In a specific embodiment, there are two locking blocks 21 and two locking grooves 111, with each locking block 21 corresponding to one of the two locking grooves 111. Accordingly, a top block 22 is provided below each locking block 21, and when the filter bottle 2 is installed on the connecting seat 1, each top block 22 abuts against the inner wall of the through hole 112 of the mounting bracket 11.

[0045] Please see Figure 1 and Figure 5In one embodiment of this utility model, the mounting bracket 11 is provided with a limiting groove 113 extending circumferentially therein, and the seat 12 is provided with a limiting block 121 that can be inserted into the limiting groove 113. Specifically, when installing the seat 12 onto the mounting bracket 11, it is only necessary to place the seat 12 on the mounting bracket 11 and rotate the seat 12 so that the limiting block 121 is inserted into the limiting groove 113 to complete the installation of the seat 12. This can reduce the installation difficulty of the seat 12, thereby reducing the assembly difficulty of the connecting seat 1. In a specific embodiment, the mounting bracket 11 is provided with two limiting grooves 113 extending circumferentially therein, and the seat 12 is provided with two limiting blocks 121. The two limiting blocks 121 are provided in a one-to-one correspondence with the two limiting grooves 113. In addition, the number of limiting grooves 113 and limiting blocks 121 can also be three, four, etc. In this embodiment, the mounting bracket 11 extends upward to form a first extension block 1131, and the end of the first extension block 1131 away from the mounting bracket 11 extends along the circumference of the mounting bracket 11 to form a second extension block 1132. The limiting groove 113 is formed by the first extension block 1131, the second extension block 1132 and the mounting bracket 11.

[0046] Please see Figure 5 and Figure 8 In one embodiment of this utility model, the mounting bracket 11 is provided with a stop block 114, and the seat 12 is provided with an arc-shaped block 122. When the limiting block 121 is inserted into the limiting groove 113, the arc-shaped block 122 can abut against the stop block 114. In this embodiment, the mounting bracket 11 has a receiving groove, the seat 12 is received in the receiving groove, and the stop block 114 is provided on the inner wall of the receiving groove. Specifically, when the limiting block 121 is inserted into the limiting groove 113, the stop block 114 is located directly above the arc-shaped block 122 and can abut against the arc-shaped block 122. Thus, the position of the seat 12 can be locked in the vertical direction, ensuring the reliability of the seat 12 when it is installed on the mounting bracket 11. When the limiting block 121 is disengaged from the limiting groove 113, the stop block 114 and the arc-shaped block 122 are misaligned. At this time, the seat 12 can be removed by lifting it upwards. In one specific embodiment, there are two stop blocks 114, and two arc-shaped blocks 122 are correspondingly provided on the base 12, with the two stop blocks 114 and the two arc-shaped blocks 122 arranged in a one-to-one correspondence. In addition, the number of stop blocks 114 and arc-shaped blocks 122 can also be three, four, etc.

[0047] Please see Figure 4 , Figure 5 and Figure 7In one embodiment of this utility model, the valve core 13 is provided with a locking part 131 corresponding to the locking groove 111. The locking part 131 can be inserted into the locking groove 111. An elastic element 132 is provided between the end of the valve core 13 away from the mounting bracket 11 and the seat 12. The elastic element 132 can drive the valve core 13 to move towards the mounting bracket 11. In this embodiment, the seat 12 has two channels, and the valve core 13 is provided with corresponding insertion rods 133 inserted into the two channels. Specifically, during the disassembly of filter bottle 2, as filter bottle 2 is gradually removed, valve core 13 moves downward under its own weight and the thrust of elastic element 132, causing locking part 131 to gradually insert into the second groove 1112 of locking groove 111. Once filter bottle 2 is completely removed, locking part 131 is inserted into the second groove 1112. At this point, mounting bracket 11 and valve core 13 cannot rotate relative to each other, and due to the restriction of insertion rod 133, seat 12 and valve core 13 cannot rotate relative to each other. This prevents relative rotation between seat 12 and mounting bracket 11 after filter bottle 2 is removed, ensuring the integrity of connecting seat 1. Correspondingly, both sides of locking block 21 are inclined, meaning both sides of locking block 21 are inclined slopes. This allows locking block 21 to gradually lift valve core 13 as filter bottle 2 rotates during installation, preventing jamming during filter bottle 2 installation. In this embodiment, the locking part 131 is formed by creating multiple grooves on the valve core 13, with the portion between two adjacent grooves constituting the locking part 131. In a specific embodiment, the elastic element 132 can be a spring, and the structure and use of springs are relatively mature, which can reduce the manufacturing cost of the water purification device.

[0048] Please see Figure 2 and Figure 3In one embodiment of this utility model, the filter bottle 2 includes a bottle body 23 with a filtration chamber, a filter element 24 disposed in the filtration chamber, and a first fixing block 25 and a second fixing block 26 respectively disposed at both ends of the filter element 24. The first fixing block 25 and the bottle body 23 both pass through the mounting bracket 11 and are inserted into the valve core 13, forming an inlet chamber 134 and an outlet chamber 135 together with the valve core 13. The filter element 24 divides the filtration chamber to form an inlet area 241 communicating with the inlet chamber 134 and an outlet area 242 communicating with the outlet chamber 135. In this embodiment, the locking block 21 and the top block 22 are both disposed on the bottle body 23 and integrally formed with the bottle body 23. The base 12 is provided with an inlet 123 and an outlet 124 spaced apart, the inlet 123 communicating with the inlet chamber 134 and the outlet 124 communicating with the outlet chamber 135. Specifically, during water supply, the water flowing in from the inlet 123 flows sequentially through the inlet chamber 134 and the inlet area 241, passes through the filter element 24, and then flows sequentially through the outlet area 242 and the outlet chamber 135, finally flowing out from the outlet 124. In a specific embodiment, the first fixing block 25 is provided with a first annular protrusion 251 and a second annular protrusion 252. The outer side of the first annular protrusion 251 abuts against the inner wall of the filter chamber, and a connecting hole 112 is opened on the first annular protrusion 251 to connect the inlet chamber 134 and the inlet area 241. Furthermore, the valve core 13 has a chamber, in which an annular partition plate 136 is provided. The outer side of the second annular protrusion 252 abuts against the inner side of the annular partition plate 136 to divide the chamber of the valve core 13 into the inlet chamber 134 and the outlet chamber 135. To ensure the water purification device is airtight, sealing rings are provided between the valve core 13 insert rod 133 and the inner wall of the channel of the seat 12, between the outer side of the second annular protrusion 252 and the inner side of the annular partition plate 136, and between the outer side of the bottle body 23 and the inner side of the chamber of the valve core 13. Each sealing ring is installed by opening a groove.
