Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and more specifically, to a filter cartridge installation support, a turntable, a water circuit board, and a water purifier. Background Technology

[0002] As users' demands for daily drinking water quality continue to increase, water purification equipment has entered thousands of households. Water purification equipment typically includes a water circuit board, filter cartridges, control devices, and corresponding piping. The water circuit board provides the chamber for liquid exchange during the operation of the filter cartridges, and mounting brackets are usually installed on the water circuit board to install the filter cartridges, so as to realize the water flow between the filter cartridge inlet and the water circuit board.

[0003] In practical use, filter cartridges need to be replaced regularly, making the ease of installation and waterproof sealing between the filter cartridge and the water circuit board crucial. For quick installation, a common method is to use a rotary installation for the filter cartridge and mounting base. The mounting base also includes a turntable with water inlets corresponding to those on the water circuit board and filter cartridge. After the filter cartridge is positioned and installed on the turntable, it rotates synchronously. When the filter cartridge and turntable rotate together until the water inlet position is misaligned with the water inlet position on the water circuit board, the water circuit is disconnected. When the water inlet position aligns with the water inlet position on the water circuit board, the water circuit is connected. The water inlet positions are accurately aligned only after the filter cartridge is fully rotated into place. A sealing structure between the water circuit board and the turntable prevents leakage during installation. This method allows users to easily remove and replace the filter cartridge themselves, offering high operational convenience. Patents such as CN209596696U, CN205634927U, and CN207286876U all employ the aforementioned rotary table installation method, utilizing the rotary table structure to control the flow of water between the filter element and the water inlet of the water circuit board. However, in practice, it has been found that even after repeated filter element removal and installation on the water circuit board, occasional water leakage still easily occurs at the water inlet, and the occurrence is highly random, making it difficult to accurately diagnose the cause of the leakage. This significantly impacts the user experience and affects the long-term safety of the water purification equipment. Utility Model Content

[0026] 3. Beneficial effects

[0027] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0028] (1) The filter cartridge installation turntable of this utility model provides a support component at the bottom of the inner cavity flow channel of the turntable water inlet, and uses the partition rib to provide a support path for the sealing ring in the inner cavity flow channel, thereby effectively alleviating the problem of deformation and displacement of the sealing ring under long-term use. It has been verified that it effectively improves the sealing stability between the turntable body and the water inlet of the water circuit board, and avoids water leakage and seepage problems when disassembling and assembling the filter cartridge.

[0029] (2) The filter element installation turntable of this utility model has a dividing rib extending in an arc shape in the inner cavity of the turntable water outlet, and the center of the arc of the dividing rib is concentrically distributed with the axis of rotation of the turntable body, so that the extension direction of the dividing rib tends to be consistent with the compression rotation direction of the sealing ring, avoiding the opposite compression trend of the sealing ring, further avoiding the sealing ring from being displaced under force, and ensuring the stability of the support path of the sealing ring.

[0030] (3) The filter cartridge installation turntable of this utility model has an expansion groove around the inner wall of the inner cavity flow channel end of the turntable water inlet in the circumferential direction. The inner diameter of the expansion groove is larger than the inner diameter of the inner cavity flow channel. The support is placed in the expansion groove for installation, so as to compensate for the flow of the inner cavity flow channel, so as to avoid occupying the flow space of the inner cavity flow channel as much as possible, and still ensure the end water flow demand of the inner cavity flow channel.

[0053] The present invention will be further described below with reference to the embodiments.

[0054] Example

[0055] Combination Figures 1-13 As shown, in a water purification device, a ring-shaped mounting base 310 is typically installed at the water inlet position of the water circuit plate 300. The inner cavity formed by the mounting base 310 can be fitted with the water inlet mounting end 203 of the filter element 200. The turntable 100 is installed in the inner cavity formed by the mounting base 310 and pressed against the water circuit plate 300 by the mounting base 310. The turntable 100 is located between the water circuit plate 300 and the water inlet mounting end 203 of the filter element 200. The mounting base 310 surrounds the outside of the turntable 100 and presses the turntable 100 to prevent axial movement. The filter element 200 has multiple filter element water inlets 201, and the turntable 100 has multiple turntable water inlets 111 corresponding to each other. The two ends of the turntable water inlets 111 respectively mate with the water inlets on the filter element 200 and the water inlets on the water circuit plate 300. When installing filter element 200, it is first positioned and connected to turntable 100 with the water inlet position aligned. Then, the entire unit is rotated to adjust the connection or disconnection status with the water inlet position on the water circuit board. The conventional installation method of filter element 200 and water circuit board 300 at this time will not be described in detail.

[0056] It should be noted that this embodiment first provides a filter element installation support member 120, which is configured to be installed in the inner cavity flow channel 114 of the filter element turntable inlet 111 and located at one end of the inner cavity flow channel 114 facing the water channel plate 300; the support member 120 includes a peripheral annular wall that can form an inner flow channel, which is configured to communicate with the inner cavity flow channel 114; in particular, at least a portion of the peripheral annular wall of the support member 120 extends in the inner cavity flow channel 114 and is configured to divide the end of the inner cavity flow channel 114 facing the water channel plate 300 into multiple flow channels; or / and, the inner flow channel of the support member 120 is provided with a partition rib 123, which is configured to divide the end of the inner cavity flow channel 114 facing the water channel plate 300 into multiple flow channels. Here, "or / and" means that, in practice, at least a portion of the peripheral annular wall of the support member 120 is used as a partition rib to spatially divide the inner cavity flow channel 114, or a partition rib 123 is provided in the inner flow channel of the support member 120 to spatially divide the inner cavity flow channel 114. Both methods can be selected or both can be used simultaneously.

[0057] Combination Figures 8-10 As shown, in one practical implementation, the peripheral ring wall of the support member 120 includes an outer support portion 121, which is configured to cooperate with the inner cavity flow channel 114 of the turntable sprue 111. The two ends of the outer support portion 121 are connected by an inner support portion 122, which is configured to separate the inner cavity flow channel 114. A partition rib 123 is also provided between the outer support portion 121 and the inner support portion 122, which spatially separates the internal flow channel of the support member 120. In this case, the inner support portion 122 and the partition rib 123 can be used together to spatially separate the inner cavity flow channel 114 of the turntable sprue 111.

[0058] This embodiment also provides a filter cartridge installation turntable. The turntable 100 includes a turntable body 110, which is configured to be installed in the inner cavity of the mounting base 310 on the water channel plate 300. The turntable body 110 is provided with a turntable water inlet 111, which is configured to be compatible with the water inlets on the filter cartridge 200 and the water channel plate 300, respectively. A support member 120 is provided in the inner cavity flow channel 114 of the turntable water inlet 111. The support member 120 is located at the end of the inner cavity flow channel 114 facing the water channel plate 300. The support member 120 has a partition rib 123, which extends in the inner cavity flow channel 114 of the turntable water inlet 111 and divides the end of the inner cavity flow channel 114 facing the water channel plate 300 into multiple flow channels. The extension height of the partition rib 123 in the inner cavity flow channel 114 is not higher than the end face height of the inner cavity flow channel 114 facing the water channel plate 300.

[0059] In practice, the applicant conducted long-term tracking and research to address the occasional water leakage during the disassembly and replacement of filter element 200, and finally made some discoveries. Currently, in the installation structure of filter element 200 and water circuit board 300, to ensure waterproof sealing, a sealing ring is installed between the turntable body 110 and the water circuit board 300 below. Specifically, each water inlet on the water circuit board 300 has an installation groove on its outer periphery, and a protruding sealing ring is arranged around the installation groove. This sealing ring is pressed between the bottom of the turntable body 110 and the water inlet of the water circuit board 300. When the turntable water inlet 111 on the turntable body 110 corresponds to the water inlet position on the water circuit board 300, the periphery is sealed using the sealing ring. During the rotation of the turntable body 110, the bottom surface of the turntable body 110 is always pressed against each sealing ring during rotation, again using the sealing ring for waterproofing. The rotary inlet 111 itself has a certain aperture, especially for high-flow filter cartridge 200 equipment, where the aperture of the rotary inlet 111 may be larger. When the rotary inlet 111 is rotated and passes through the inner cavity opening area, the upper part of the sealing ring is in an open and suspended state. Due to the elasticity of the sealing ring, it will easily return to its original position and spring back when it is in the inner cavity opening area of ​​the rotary inlet 111. After passing through the inner cavity opening area of ​​the rotary inlet 111, the sealing ring is then repositioned by the rotary body 1. 10. The bottom surface is re-squeezed and pulled; in practice, the turntable body 110 usually has multiple turntable water inlets 111, so the sealing ring may be repeatedly rotated and squeezed, reset and bounced outward, and then rotated and squeezed again. With long-term use, the sealing ring may be partially deformed, pulled and displaced, or even taken out of the mounting groove, resulting in water leakage. This situation is relatively rare, and the sealing ring is hidden under the inner turntable body 110, making it extremely hidden and difficult for users to notice.

[0060] Based on this discovery, the applicant optimized the design by setting a support member 120 inside the bottom of the inner cavity flow channel 114, that is, setting the support member 120 inside the end of the inner cavity flow channel 114 that is close to the water outlet of the water circuit plate 300. The partition rib 123 extends in the inner cavity flow channel 114, thereby providing a support path for the sealing ring in the inner cavity flow channel 114 with a certain aperture range. When the sealing ring is in the opening area of ​​the inner cavity of the rotary water outlet 111, it can be further and continuously squeezed by the partition rib 123, instead of being in an open and suspended state in a larger aperture range. This can effectively alleviate the deformation and displacement problem of the sealing ring under long-term use. It has been verified that this effectively improves the sealing stability between the rotary body 110 and the water outlet of the water circuit plate 300, and avoids water leakage problems when disassembling and assembling the filter element 200.

[0061] In practice, the extension height of the partition rib 123 in the inner cavity flow channel 114 is not higher than the end face height of the inner cavity flow channel 114 facing the water channel plate 300. That is, the bottom end of the partition rib 123 will not protrude beyond the bottom surface of the turntable body 110, so as to ensure the sealing between the bottom surface of the turntable body 110 and the upper water inlet of the water channel plate 300. In this embodiment, the bottom surface of the turntable body 110 refers to the wall surface of the turntable body 110 that is close to the water channel plate 300. More preferably, the end face height of the partition rib 123 and the inner cavity flow channel 114 in the direction facing the water channel plate 300 is kept at the same level. That is, the bottom of the partition rib 123 is kept at the same level as the bottom surface of the turntable body 110, so that the compression effect of the partition rib 123 and the bottom surface of the turntable body 110 on the sealing ring is more similar. In practice, the bottom surface height of the partition rib 123 can be slightly lower than the bottom surface height of the turntable body 110, which can also achieve the effect of providing a support path for the sealing ring.

[0062] To further optimize the supporting path function of the partition rib 123, in some embodiments, the partition rib 123 on the support member 120 extends in an arc shape in the inner cavity flow channel 114 of the turntable nozzle 111, and the arc center of the partition rib 123 is concentrically distributed with the axis of rotation of the turntable body 110. Combined with Figure 13 As shown, when the turntable body 110 rotates synchronously with the filter element 200, it rotates around the rotation axis A. The arc center of the partition rib 123 is also the axis A. Therefore, during the rotation, it has a longer support path, and the extension direction of the partition rib 123 tends to be consistent with the direction of compression and rotation of the sealing ring. This avoids the opposite compression and pulling trend of the sealing ring in the lateral direction, further avoiding the sealing ring from being displaced under force, and ensuring the stability of the support path of the sealing ring.

[0063] To ensure the stability of the support path of the partition rib 123 and prevent it from rotating within the turntable nozzle 111, in some embodiments, it is further preferred that a limiting part 115 is provided between the turntable nozzle 111 and the support member 120. The limiting part 115 is configured to restrict the support member 120 from rotating within the inner cavity flow channel 114 of the turntable nozzle 111. (See also...) Figure 6 and Figure 7As shown, in one embodiment, an expansion groove 116 is provided around the circumferential portion of the inner wall of the inner cavity flow channel 114 of the rotary water inlet 111. The expansion groove 116 extends downward to a certain depth to accommodate the support member 120. The inner diameter of the expansion groove 116 is larger than the inner diameter of the inner cavity flow channel 114, thus forming a limiting part 115 between the end of the expansion groove 116 and the adjacent inner wall of the inner cavity flow channel 114. The support member 120 is placed downward into the expansion groove 116, and the end of the support member 120 abuts against the limiting part 115 in the corner area. At this time, both ends of the support member 120 are abutted and fixed by the limiting part 115, effectively preventing rotation. The installation method of the expansion groove 116 can also compensate for the flow rate at the end of the inner cavity flow channel 114. Other limiting methods can also be used in practice, which will not be elaborated here.

[0064] As for different designs of the support member 120, one or more separate dividing ribs 123 can be set as the support member 120 and distributed at intervals in the inner cavity flow channel 114. The support member 120 can be integrally formed with the inner cavity flow channel 114, or the support member 120 can be set as an integral structure independent of the inner cavity flow channel 114, which is more convenient for installation. In this case, it is preferable that the support member 120 has an internal flow channel formed inside, and this internal flow channel is correspondingly connected to the inner cavity flow channel 114 of the turntable sprue 111. For example, combined with Figures 8-11 As shown, in one embodiment, the support member 120 includes an outer support portion 121 that is fitted into the inner cavity of the turntable sprue 111. If the support member 120 is placed using the aforementioned expansion groove 116 structure, the outer support portion 121 can be configured as an arc-shaped portion that matches the expansion groove 116, and the radial extension width of the outer support portion 121 is approximately the same as the radial extension width of the expansion groove 116, so as to avoid occupying the flow space of the inner cavity flow channel 114 as much as possible, while still ensuring the water flow rate at the end of the inner cavity flow channel 114; the two ends of the outer support portion 121 are connected by an inner support portion 122, and an internal flow channel is formed between the outer support portion 121 and the inner support portion 122; the inner support portion 122 extends in the inner cavity flow channel 114 of the turntable sprue 111, and at this time, the inner support portion 122 acts as a partition rib 123 to spatially divide the inner cavity flow channel 114. At this point, a single internal flow channel is formed between the outer support portion 121 and the inner support portion 122. The inner support portion 122 is directly used as a partition rib 123 to provide a support path for the sealing ring. This design, while increasing the support path, minimizes the space occupied by the partition rib 123 within the internal flow channel 114 to meet the water flow requirements of the internal flow channel 114 and avoids excessively affecting the water flow rate of the internal flow channel 114. Preferably, the inner support portion 122 extends radially along the internal flow channel 114, dividing the internal flow channel 114 into two. In some designs, a partition rib 123 is further provided between the outer support portion 121 and the inner support portion 122 of the support member 120. The partition rib 123 spatially divides the internal flow channel of the support member 120. Figures 8-13As shown, the partition rib 123 divides the internal flow channel between the outer support portion 121 and the inner support portion 122 into a first flow channel 124 and a second flow channel 125. Both the partition rib 123 and the inner support portion 122 extend inside the inner cavity flow channel 114, and a third flow channel is also formed between the inner support portion 122 and the inner wall of the inner cavity flow channel 114, thereby dividing the bottom space of the inner cavity flow channel 114 into three sets of flow channels. At this time, the partition rib 123 and the inner support portion 122 form two sets of partition rib structures, which can provide a support path for the sealing ring. While ensuring the sealing stability, it is necessary to ensure that the flow area at the bottom of the inner cavity flow channel 114 is not excessively reduced. More preferably, the inner support portion 122 and the partition rib 123 also extend in an arc shape in the inner cavity flow channel 114 of the turntable nozzle 111, and the center of the arc is concentrically distributed with the axis of rotation of the turntable body 110. The inner support 122 and the partition 123 divide the inner cavity flow channel 114 into three flow channel structures with basically the same width in the radial direction. This ensures both the end flow area of ​​the inner cavity flow channel 114 and the sufficient extension length of the inner support 122 and the partition 123, providing a sufficient support path.

[0065] In some embodiments, to achieve a tight fit between the arc-shaped outer support 121 and the expansion groove 116, it is preferable to provide multiple sets of outwardly protruding mounting ribs 126 at intervals on the arc-shaped outer wall of the outer support 121. The mounting ribs 126 extend along the vertical installation direction of the support 120, that is, along the axial direction of the outer support 121, and the mounting ribs 126 cooperate with the inner wall of the turntable sprue 111. In practice, the support 120 can be integrally molded by injection molding and needs to be installed in a tight fit with the expansion groove 116. If only the arc-shaped outer wall of the outer support 121 is directly attached to the inner wall of the expansion groove 116, due to factors such as manufacturing errors, it is easy for the outer support 121 to be difficult to embed into the expansion groove 116, resulting in a lower installation fit rate. By setting multiple sets of mounting ribs 126 for multi-point installation, slight manufacturing errors will not affect the overall installation of the support 120, resulting in a higher installation fit rate.

[0066] In some embodiments, more preferably, the partition rib 123 extends continuously and uninterruptedly in the inner cavity flow channel 114 of the rotary gate 111, so as not to form an interruption in the support path and to ensure the continuous compression sealing effect on the sealing ring.

[0067] Combination Figure 3 and Figure 4As shown, to facilitate rapid positioning between the filter element 200 and the rotary water inlet 111 during installation, in some embodiments, the top of the rotary water inlet 111 facing the filter element 200 is provided with an upwardly extending water inlet rib 112. The water inlet rib 112 can serve as a positioning element. When the water inlet mounting end 203 of the filter element 200 is screwed into the mounting base 310, the water inlet rib 112 can be fitted and inserted into the filter element water inlet 201 on the water inlet mounting end 203 to achieve positioning. More preferably, the wall surface of the rotary body 110 facing the filter element 200 is provided with an upwardly extending positioning post 113. The extension height of 113 is higher than the height of the sprue rib plate 112. The sprue mounting end 203 of the filter element 200 is provided with a corresponding positioning hole 202. The positioning post 113 preferably has a polygonal cross section to avoid rotation between it and the positioning hole 202. By setting the positioning post 113, the installation of the filter element 200 and the turntable body 110 can be pre-guided and positioned by the positioning post 113 and the positioning hole 202 before the sprue rib plate 112 contacts the filter element sprue 201, ensuring accurate matching between the two. Then, the sprue rib plate 112 is used for further guidance and positioning.

[0068] This embodiment also provides a water channel plate 300, which is provided with a mounting base 310 for mounting a filter element 200. The mounting base 310 has a turntable 100 as described above in its inner cavity. By optimizing the structure of the turntable 100, the stability of the sealing effect between the mounting base 310 and the filter element 200 on the water channel plate 300 is effectively improved.

[0069] This embodiment also provides a water purifier, including a filter element 200 and a water circuit board 300 as described above. The water outlet mounting end 203 of the filter element 200 is installed in the inner cavity of the mounting base 310 on the water circuit board 300. By optimizing the structure of the turntable 100 inside the mounting base 310, the overall performance of the water purifier is made more stable, effectively improving the user experience.
