Quick-release mechanism for filter cartridge and water purifier

Abstract

The application provides a filter core quick dismounting mechanism and a water purifier. The filter core quick dismounting mechanism comprises a mounting base body, a swing component and a filter core. The mounting base body is provided with a first locking part. The swing component is swingably arranged on the mounting base body. The filter core is provided with a second locking part and is pluggably arranged on the swing component. The filter core has a locking position and an unlocking position. The filter core can be switched between the locking position and the unlocking position by swinging the swing component. In the locking position, the second locking part is located below the first locking part and abuts against the first locking part, so that the filter core is limited on the mounting base body. In the unlocking position, the second locking part is arranged in a staggered manner with the first locking part, so that the filter core can be separated from the swing component. Through the linkage design of the locking structure composed of the first locking part and the second locking part and the swing component, only one-direction pushing and pulling and plugging operation is needed in the whole dismounting process, without rotating action, so that the operation strength can be reduced and the dismounting efficiency can be improved.

Description

Technical Field

[0001] This application relates to the field of filter cartridge installation technology, and in particular to a quick-release filter cartridge mechanism and a water purifier. Background Technology

[0002] A water purifier is a device that removes impurities, harmful substances, and microorganisms from water through technologies such as physical filtration, chemical adsorption, or membrane separation. Its core function is to improve water quality to meet safety and health requirements for drinking, domestic, or industrial use. Water purifiers typically consist of a multi-stage filter system (such as PP cotton, activated carbon, RO reverse osmosis membrane, ultrafiltration membrane, etc.). Each stage of the filter system targets different contaminants (such as sediment, residual chlorine, heavy metals, bacteria, etc.) and filters them step by step, ultimately outputting clean water.

[0003] Traditional water purifier filter cartridges are mostly installed by rotation. Whether the rotating disc is fixed on the filter cartridge or on the water circuit board, the filter cartridge needs to be rotated to be installed or removed. The rotation process is relatively strenuous and the entire disassembly and assembly process takes a lot of time. Utility Model Content

[0022] In one embodiment, the mounting base includes:

[0023] The base, wherein the arc-shaped groove is disposed on the base; and

[0024] The top seat is separate from the base and is located on top of the base. The top seat and the base form the guide groove, and the first locking part is located on the top seat.

[0025] In one embodiment, the first locking portion is provided on both opposite sides of the mounting base;

Detailed Implementation

[0049] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0050] See Figures 1-11 This invention illustrates a preferred embodiment of a filter cartridge quick-release mechanism, comprising:

[0051] Mounting base 1, the mounting base 1 is provided with a first locking part 121;

[0052] The swinging component 2 is mounted on the mounting base 1 and is swayable left and right; and

[0053] The filter element 3 is provided with a second locking part 31 and is pluggably mounted on the swinging component 2. The filter element 3 has a locking position and an unlocking position, and the filter element 3 can switch between the locking position and the unlocking position as the swinging component 2 swings.

[0054] The locking position is such that the second locking part 31 is located below the first locking part 121 and abuts against the first locking part 121, so as to restrict the filter element 3 to the mounting base 1;

[0055] The unlocking station is arranged with the second locking part 31 and the first locking part 121 offset to allow the filter element 3 to be disengaged from the swinging part 2.

[0056] The quick-release filter element mechanism of this utility model, through the locking structure composed of the first locking part 121 and the second locking part 31 and the linkage design of the swinging component 2, allows the filter element 3 to be inserted at an angle onto the swinging component 2 during installation, so that the filter element 3 can swing with the swinging component 2, and then push the filter element 3 to swing forward (to... Figure 1 Taking the direction shown as an example (positive direction is to the right), the second locking part 31 slides down to below the first locking part 121 and abuts against the first locking part 121, thus completing the locking; when the filter element 3 needs to be removed, push the filter element 3 to swing in the opposite direction (to... Figure 1 Taking the direction shown as an example (the opposite direction is to the left), slide the second locking part 31 to be misaligned with the first locking part 121 to ensure that the first locking part 121 will not interfere with the upward sliding of the second locking part 31. Then, pull the filter element 3 out of the swinging part 2 to complete the unlocking. The entire disassembly and assembly process only requires unidirectional push-pull and plug-in operations, without the need for rotation, which can reduce the intensity of operation and improve the efficiency of disassembly and assembly.

[0057] See Figures 2-3 In one embodiment, the top of the mounting base 1 is provided with a support groove 122;

[0058] The filter element 3 is provided with a support part 32, which is detachably and can swing left and right within the support groove 122 to limit the self-swing of the filter element 3 in the non-operating state. That is, by cooperating with the support part 32 of the support groove 122 provided on the top of the mounting base 1, the filter element 3 is ensured to obtain stable support and swing restraint in the locking position, effectively preventing the filter element 3 from shaking and automatically disengaging due to water flow impact, thus ensuring the stability of the installation and limiting the self-swing of the filter element 3 in the non-operating state. At the same time, the characteristic that the support part 32 can swing within the support groove 122 allows the filter element 3 to naturally avoid interference during disassembly and assembly, and the disassembly and assembly of the support part 32 and the support groove 122 can be completed with simple plugging and unplugging, which significantly improves the convenience of disassembly and assembly, improves maintenance efficiency while ensuring reliability, and thus comprehensively optimizes the practicality, durability and ease of operation of the structure.

[0059] See Figures 2-3 In one embodiment, the support groove 122 has an arc-shaped segment 1221 and a first planar segment 1222, the first planar segment 1222 being located on one side of the arc-shaped segment 1221 and extending vertically.

[0060] The support portion 32 is provided with an arc-shaped protrusion 321 and a second flat section 322. The arc-shaped protrusion 321 is adapted to the arc-shaped section 1221, that is, the arc of the arc-shaped protrusion 321 is adapted to the arc of the arc-shaped section 1221. The second flat section 322 is located on one side of the arc-shaped protrusion 321 and extends vertically, abutting against the first flat section 1222. In this way, the arc-shaped protrusion 321 and the arc-shaped section 1221 cooperate to achieve controllable swing of the support portion 32 within the support groove 122. At the same time, the rigid contact between the second flat section 322 and the first flat section 1222 forms a double limiting structure, which maintains the swing adjustment function during installation and effectively suppresses the self-swing of the support portion 32 in the non-operational state through mechanical limiting. Thus, while ensuring the stability of the filter element 3 in the locking position, it also takes into account the convenience of disassembly and assembly, significantly improving the installation accuracy, working reliability and service life of the filter element 3.

[0061] See Figures 5-6 In one embodiment, the mounting base 1 has an arcuate groove 111;

[0062] The bottom of the swinging component 2 is provided with an arc-shaped portion 21, which is adapted to the arc-shaped groove 111. That is, the arc of the arc-shaped portion 21 is adapted to the arc of the arc-shaped groove 111, and the arc-shaped portion 21 can swing left and right along the arc-shaped groove 111. In this way, by providing an arc-shaped groove 111 on the mounting base 1 and forming a matching swing pair structure with the arc-shaped portion 21 at the bottom of the swinging component 2, the filter element 3 can swing smoothly along a predetermined arc trajectory. This ensures the precise alignment of the locking part and the locking groove, and improves the stability and smoothness of the swinging process through the arc-shaped guide structure. At the same time, it simplifies the mating structure between the mounting base 1 and the swinging component 2.

[0063] See Figures 2-3 In one embodiment, the mounting base 1 has a guide groove 13 that extends along the swing direction of the swinging member 2.

[0064] The swing component 2 is provided with a guide portion 22, which is slidably disposed within the guide groove 13. Thus, by providing a guide groove 13 extending along the swing direction on the mounting base 1, and forming a sliding fit structure with the guide portion 22 of the swing component 2, the movement trajectory of the filter element 3 during swing is ensured to be precisely controllable. This improves the alignment accuracy and operational smoothness of the first locking portion 121 and the second locking portion 31, and also achieves a stable connection between the swing component 2 and the mounting base 1 through the guiding and limiting effect, enhancing the stability and reliability of the overall structure, while simultaneously achieving a simple and efficient mechanical fit.

[0065] See Figure 6 , Figure 8 as well as Figure 9 In one embodiment, the mounting base 1 includes:

[0066] Base 11, arc-shaped groove 111 is provided on base 11; and

[0067] The top seat 12 is separate from the base 11, with the top seat 12 located on top of the base 11. The top seat 12 and the base 11 together form a guide groove 13, and the first locking part 121 is located on the top seat 12. Thus, by designing the mounting base 1 as a separate structure of base 11 and top seat 12, it facilitates manufacturing, assembly, and maintenance. Furthermore, by having the base 11 and top seat 12 together form the guide groove 13, when installing the swing component 2, it is only necessary to position the arc-shaped part 21 of the swing component 2 within the arc-shaped groove 111 of the base 11, and then assemble the top seat 12 onto the base 11. This achieves precise positioning and reliable locking of the swing component 2 on the mounting base 1, significantly simplifying the installation process of the swing component 2, reducing assembly difficulty, and ensuring a balance between structural stability and ease of operation.

[0068] In one embodiment, the base 11 and the top seat 12 can be connected together by a structure such as a snap fastener or a fastener. The fastener can be any one of the following: a screw, a bolt and nut, a rivet, etc.

[0069] See Figure 7 In one embodiment, the bottom of the filter element 3 has a first flow channel 33, which is used to allow the fluid to be filtered to flow into the interior of the filter element 3 or to allow the filtered fluid to flow out from the interior of the filter element 3.

[0070] The top of the swing component 2 is provided with a connecting rod 23, which is pluggable and detachable in the first flow channel 33 and sealed with the first flow channel 33. The swing component 2 also has a second flow channel 24, which passes through the top of the connecting rod 23 and the bottom of the swing component 2. The upper end of the second flow channel 24 is connected to the first flow channel 33.

[0071] The mounting base 1 has a third flow channel 112. The upper end of the third flow channel 112 penetrates the end faces of the mounting base 1 and the bottom of the swinging component 2, which are facing each other. The upper end of the third flow channel 112 connects to the lower end of the second flow channel 24 and is sealed with the second flow channel 24. The other end of the third flow channel 112 penetrates the side wall of the mounting base 1 and is connected to a water supply source or water-using device. In this way, the filter element 3 and the swinging component 2 are quickly connected through the pluggable sealing fit between the connecting rod 23 and the first flow channel 33, while ensuring reliable connection between the first flow channel 33 and the second flow channel 24. In addition, the sealing fit between the bottom of the swinging component 2 and the end face of the mounting base 1 ensures reliable connection between the second flow channel 24 and the third flow channel 112. This achieves efficient fluid transmission while effectively preventing leakage, combining the advantages of quick assembly and disassembly and reliable sealing. The overall structure is simple, practical, and inexpensive to manufacture, reducing the overall cost of the quick assembly and disassembly mechanism for the filter element.

[0072] See Figure 7 In one embodiment, the side wall of the first flow channel 33 is provided with a first sealing member (not shown in the figure). The first sealing member is arranged around the outer peripheral wall of the connecting rod 23 and is sealed to the outer peripheral wall of the connecting rod 23 to seal the gap between the first flow channel 33 and the connecting rod 23, thereby sealing the gap between the first flow channel 33 and the second flow channel 24 to prevent water leakage.

[0073] The mounting base 1 and the bottom of the swinging component 2 are provided with a second sealing element 4. The second sealing element 4 is arranged around the third flow channel 112 and the second flow channel 24. The second sealing element 4 abuts against the bottom of the swinging component 2 to seal the gap between the third flow channel 112 and the second flow channel 24 and prevent water leakage.

[0074] In one embodiment, the sidewall of the first flow channel 33 has a first embedding groove, the first embedding groove is arranged around the first flow channel 33, and the first seal is embedded in the first embedding groove to reliably fix the first seal on the filter element 3, ensuring that the inner ring of the first seal can fit tightly against the outer peripheral wall of the connecting rod 23.

[0075] The mounting base 1 and the bottom of the swing component 2 have a second embedding groove on their opposite end faces. The second embedding groove surrounds the third flow channel 112. The second seal 4 is embedded in the second embedding groove to reliably fix the second seal 4 to the mounting base 1 and ensure that the second seal 4 can fit tightly with the bottom of the swing component 2.

[0076] In one embodiment, both the first sealing element and the second sealing element 4 are sealing rings. Thus, by using sealing rings as the first and second sealing elements 4, the standard part characteristics of sealing rings are utilized to reduce production costs and assembly difficulty, while fully leveraging the excellent elastic sealing performance of sealing rings to ensure efficient sealing at the connections of each flow channel. This achieves reliable leak prevention while also offering advantages such as simple structure, convenient maintenance, and strong versatility.

[0077] Of course, in other embodiments, both the first sealing element and the second sealing element 4 can be rubber flange gaskets, air-expanding sealing strips, or other structures.

[0078] In one embodiment, a first locking part 121 is provided on both opposite sides of the mounting base 1;

[0079] Each side of the filter element 3 is provided with a second locking part 31. When the filter element 3 is in the locking position, the second locking part 31 is located below the corresponding first locking part 121 and abuts against the corresponding first locking part 121. In this way, the first locking parts 121 symmetrically arranged on both sides of the mounting base 1 cooperate with the corresponding second locking parts 31 arranged on both sides of the filter element 3 to achieve a bidirectional locking structure, which enhances the assembly stability and positioning accuracy of the filter element 3, ensures that the filter element 3 is firmly fixed in the mounting base 1, reduces the risk of displacement or loosening caused by uneven force on one side, and improves the reliability and service life of the overall structure.

[0080] In one embodiment, three first locking parts 121 are provided on each of the opposite sides of the mounting base 1, and a clearance groove is formed between two adjacent first locking parts 121. The clearance groove is used to allow the corresponding second locking part 31 to move in and out of the mounting base 1.

[0081] Three second locking parts 31 are provided on each of the opposite sides of the filter element 3. When the filter element 3 is in the locking position, the second locking parts 31 are located below the corresponding first locking parts 121 and abut against the corresponding first locking parts 121. In this way, by symmetrically setting three first locking parts 121 and adjacent clearance grooves on both sides of the mounting base 1, a multi-level locking cooperation is formed with the three second locking parts 31 corresponding to both sides of the filter element 3. The clearance grooves enable the smooth entry and exit of the second locking parts 31 to improve the convenience of disassembly and assembly. The mutual abutment of multiple sets of locking structures in the locking position forms multiple limits, which significantly enhances the stability and reliability of the filter element 3 installation. At the same time, the assembly process is optimized to ensure that the filter element 3 can effectively resist water flow impact in the locking state, thus improving the overall practicality and durability of the structure.

[0082] In one embodiment, among the three first locking portions 121 located on the same side, the bottom of the middle first locking portion 121 is provided with a first flat portion 1211, and the bottom of the remaining first locking portions 121 are provided with a first inclined surface 1212, the first inclined surface 1212 being inclined downward toward the adjacent clearance groove.

[0083] Of the three second locking portions 31 located on the same side, the bottom of the middle second locking portion 31 is provided with a second flat portion 311, which abuts against the first flat portion 1211. The top of the remaining second locking portions 31 is provided with a second inclined surface 312, which has the same slope as the first inclined surface 1212 and abuts against the first inclined surface 1212. Thus, by forming a planar contact between the first flat portion 1211 of the middle first locking portion 121 and the second flat portion 311 of the middle second locking portion 31, the main load-bearing support is achieved. At the same time, by utilizing the first inclined surface 1212 of the two sides of the first locking portion 121 and the second inclined surface 312 of the corresponding second locking portion 31 to form an oblique fit, stable load-bearing and accurate positioning in the locked state are ensured. The oblique guiding effect significantly reduces the assembly resistance, allowing the filter element 3 to be smoothly installed. This improves the ease of assembly while ensuring the reliability and stability of the locking structure, effectively preventing the filter element 3 from accidentally loosening under water flow conditions, and enhancing the overall performance and durability of the product.

[0084] Of course, in other embodiments, each side of the mounting base 1 may have only one first locking part 121; correspondingly, each side of the filter element 3 may have only one second locking part 31.

[0085] A preferred embodiment of this utility model provides a water purifier, including the above-mentioned quick-release filter mechanism.

[0086] The water purifier of this utility model, due to the adoption of the aforementioned quick-release filter cartridge mechanism, also utilizes the locking structure composed of the first locking part 121 and the second locking part 31, along with the linkage design of the swinging component 2. When installing the filter cartridge 3, the filter cartridge 3 is inserted obliquely onto the swinging component 2, allowing the filter cartridge 3 to swing with the swinging component 2. Then, the filter cartridge 3 is pushed to swing forward (to... Figure 1 Taking the direction shown as an example (positive direction is to the right), the second locking part 31 slides down to below the first locking part 121 and abuts against the first locking part 121, thus completing the locking; when the filter element 3 needs to be removed, push the filter element 3 to swing in the opposite direction (to... Figure 1 Taking the direction shown as an example (the opposite direction is to the left), slide the second locking part 31 to be misaligned with the first locking part 121 to ensure that the first locking part 121 will not interfere with the upward sliding of the second locking part 31. Then, pull the filter element 3 out of the swinging part 2 to complete the unlocking. The entire disassembly and assembly process only requires unidirectional push-pull and plug-in operations, without the need for rotation, which can reduce the intensity of operation and improve the efficiency of disassembly and assembly.
