Description

Technical Field

[0001] This application relates to the field of filter cartridge installation technology, and in particular to a filter cartridge installation assembly 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

[0008] The filter element is provided with a locking part and is pluggably mounted on the swinging component. The filter element has a locking position and an unlocking position and can switch between the locking position and the unlocking position as the swinging component swings.

[0009] The locking position is where the locking part engages with the locking groove to restrict the filter element onto the mounting base;

[0010] The unlocking station is where the locking part disengages from the locking groove, allowing the filter element to detach from the swinging component.

[0011] In one embodiment, the filter element is provided with a handle, which can swing up and down relative to the filter element; when the handle swings upward, the handle can be erected on the filter element; when the handle swings downward, the handle can be placed horizontally on the filter element.

[0012] The mounting base and the handle each have a slot and a locking protrusion, respectively. The locking protrusion and the slot can be plugged and unplugged to restrict the swing of the filter element when it is in the locking position.

[0013] In one embodiment, the mounting base is further provided with an arc-shaped track extending in the swing direction of the swinging component. The arc-shaped track is obliquely downward toward the opening of the locking groove. The arc-shaped track is connected to the bottom wall of the locking groove. The arc-shaped track is slidably engaged with the locking part to guide the locking part into the locking groove.

[0014] In one embodiment, the mounting base has an arcuate groove;

[0015] The bottom of the swinging component is provided with an arc-shaped part, which is adapted to the arc-shaped groove, and the arc-shaped part can swing left and right along the arc-shaped groove.

[0016] In one embodiment, the mounting base has a guide groove that extends along the swing direction of the swinging component;

[0017] The swing component is provided with a guide portion, which is slidably disposed within the guide groove.

[0018] In one embodiment, the mounting base includes:

[0019] The base has the locking groove, the arc-shaped groove, the guide groove, and the mounting port. One end of the guide groove is closed, and the other end of the guide groove is connected to the mounting port, which allows the guide part to enter and exit the guide groove.

[0020] A limiting member is provided separately from the base. The limiting member is located on the base and blocks the mounting opening to restrict the guide portion within the guide groove.

[0021] In one embodiment, the bottom of the filter element has a first flow channel for allowing fluid to be filtered to flow into the interior of the filter element or for allowing filtered fluid to flow out of the interior of the filter element.

[0022] The top of the swing component is provided with a connecting rod, which is pluggable into the first flow channel and sealed with the first flow channel. The swing component also has a second flow channel, which passes through the top of the connecting rod and the bottom of the swing component, and the second flow channel communicates with the first flow channel.

[0023] The mounting base has a third flow channel, which penetrates the end face of the mounting base and the bottom of the swing component facing each other. The third flow channel communicates with the second flow channel and is sealed to the second flow channel.

[0024] In one embodiment, the sidewall of the first flow channel is provided with a first sealing element, which is disposed around the outer peripheral wall of the connecting rod and seals with the outer peripheral wall of the connecting rod.

[0025] The mounting base and the bottom of the swing component are provided with a second sealing element on their opposite end faces. The second sealing element surrounds the third flow channel and the second flow channel, and abuts against the bottom of the swing component.

[0030] The filter cartridge installation assembly of this utility model, through the linkage design of the swinging component and the locking structure, allows the filter cartridge to be installed at an angle by inserting it into the swinging component, so that the filter cartridge can swing with the swinging component. Then, the filter cartridge is pushed to swing forward (in this embodiment, forward is to the right), so that the locking part slides into the locking groove to complete the locking. When the filter cartridge needs to be removed, the filter cartridge is pushed to swing in the opposite direction (in this embodiment, reverse is to the left), so that the locking part is disengaged from the locking groove. Then, the filter cartridge is pulled out from the swinging component to unlock. The entire disassembly and assembly process only requires unidirectional pushing, pulling and inserting operations, without the need for rotation, which can reduce the operation intensity and improve the disassembly and assembly efficiency.

[0046] 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.

[0047] See Figures 1-11 This invention illustrates a preferred embodiment of a filter cartridge mounting assembly, comprising:

[0048] Mounting base 1, mounting base 1 has a locking groove 111;

[0049] The swinging component 2 is mounted on the mounting base 1 and is swayable left and right; and

[0050] The filter element 3 is provided with a locking part 31. The filter element 3 is pluggably mounted on the swinging part 2. The filter element 3 has a locking position and an unlocking position. The filter element 3 can switch between the locking position and the unlocking position as the swinging part 2 swings.

[0051] The locking position is achieved by the locking part 31 engaging with the locking groove 111 to restrict the filter element 3 onto the mounting base 1;

[0052] The unlocking station is where the locking part 31 disengages from the locking groove 111, so that the filter element 3 can disengage from the swinging part 2.

[0053] The filter element installation assembly of this utility model, through the linkage design of the swinging component 2 and the locking structure, allows the filter element 3 to be installed at an angle by inserting it into the swinging component 2, so that the filter element 3 can swing with the swinging component 2. Then, the filter element 3 is pushed to swing forward (in this embodiment, forward is to the right), so that the locking part 31 slides into the locking groove 111 to complete the locking. When the filter element 3 needs to be removed, the filter element 3 is pushed to swing in the opposite direction (in this embodiment, reverse is to the left), so that the locking part 31 is disengaged from the locking groove 111. Then, the filter element 3 is pulled out from the swinging component 2 to unlock. The entire disassembly and assembly process only requires unidirectional pushing, pulling and inserting operations, without the need for rotation, which can reduce the operation intensity and improve the disassembly and assembly efficiency.

[0054] It can be understood that when the filter element 3 is in the locked position, the filter element 3 is vertically mounted on the mounting base 1, that is, the axis of the filter element 3 is parallel to the vertical direction.

[0055] See Figures 1-2 In one embodiment, the filter element 3 is provided with a handle 32, which can swing up and down relative to the filter element 3; when the handle 32 swings upward, the handle 32 can be erected on the filter element 3 for easy gripping and carrying; when the handle 32 swings downward, the handle 32 can be placed horizontally on the filter element 3 to store the handle 32 in the filter element 3, avoiding the handle 32 taking up too much space and saving space.

[0056] In the mounting base 1 and the handle 32, one has a slot 321 and the other has a snap-fit ​​protrusion 131. When the handle 32 is placed horizontally on the filter element 3, the snap-fit ​​protrusion 131 and the slot 321 can be inserted and removed to limit the swing of the filter element 3 in the locked position, so that the filter element 3 is reliably installed on the mounting base 1, ensuring the stability of the installation during the water flow process and effectively preventing the filter element 3 from accidentally disengaging. When the handle 32 swings upward, the snap-fit ​​protrusion 131 disengages from the slot 321. The operation is simple and convenient, which can improve the efficiency of disassembly and assembly of the filter element 3.

[0057] See Figures 1-2 as well as Figure 9 In one embodiment, the handle 32 is provided with a positioning part, and the slot 321 is provided on the positioning part;

[0058] The mounting base 1 has a positioning groove 132, and a snap-fit ​​protrusion 131 is provided in the positioning groove 132. While the snap-fit ​​protrusion 131 and the snap-fit ​​groove 321 are engaged, the positioning part is provided in the positioning groove 132 to increase the connection stability between the handle 32 and the mounting base 1, so that the filter element 3 is more securely installed on the mounting base 1.

[0059] See Figures 3-4 In one embodiment, the mounting base 1 is further provided with an arc-shaped track 112, which extends in the swing direction of the swinging component 2. The arc-shaped track 112 is obliquely downward toward the opening of the locking groove 111 and connects to the bottom wall of the locking groove 111. The arc-shaped track 112 is slidably engaged with the locking part 31 to guide the locking part 31 into the locking groove 111. By providing an obliquely downward arc-shaped track 112 on the mounting base 1 and forming a sliding engagement structure with the locking part 31, the guiding effect of the arc-shaped track 112 ensures that the locking part 31 slides accurately into the locking groove 111 along a predetermined path. This optimizes the smoothness of the swing locking of the filter element 3 and enhances the reliability and assembly convenience of the locking structure (including the locking groove 111 and the locking part 31) by using gravity-assisted locking through the obliquely downward track design.

[0060] See Figures 5-6 In one embodiment, the mounting base 1 has an arcuate groove 113;

[0061] The bottom of the swinging component 2 is provided with an arc-shaped portion 21, which is adapted to the arc-shaped groove 113. That is, the arc of the arc-shaped portion 21 and the arc of the arc-shaped groove 113 are adapted to each other, and the arc-shaped portion 21 can swing left and right along the arc-shaped groove 113. In this way, by setting the arc-shaped groove 113 on the mounting base 1 and forming a swing pair structure adapted to 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 portion 31 and the locking groove 111, and improves the stability and smoothness of the swing 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.

[0062] See Figure 8 and Figure 10 In one embodiment, the mounting base 1 has a guide groove 114 that extends along the swing direction of the swinging member 2.

[0063] The swing component 2 is provided with a guide portion 22, which is slidably disposed within the guide groove 114. Thus, by providing a guide groove 114 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 locking portion 31 and the locking groove 111, 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.

[0064] See Figures 7-8 as well as Figure 10 In one embodiment, the mounting base 1 includes:

[0065] The base 11 has a locking groove 111, an arc-shaped track 112, an arc-shaped groove 113, a guide groove 114, and a mounting port 115. One end of the guide groove 114 is closed, and the other end of the guide groove 114 is connected to the mounting port 115. The mounting port 115 allows the guide part 22 to enter and exit the guide groove 114.

[0066] The limiting member 12 is separately set from the base 11 and is located on the base 11. The limiting member 12 blocks the mounting opening 115 to restrict the guide part 22 within the guide groove 114. That is, the mounting base 1 is a split structure, with the base 11 integrating the locking groove 111, the arc-shaped track 112, the arc-shaped groove 113, and the guide groove 114 with the mounting opening 115. With the limiting member 12 blocking the mounting opening 115, the reliable limiting and stable sliding of the guide part 22 within the guide groove 114 is achieved, and the insertion of the guide part 22 during installation is also convenient, which also facilitates the installation of the swing component 2. While ensuring structural stability, it also improves the ease of assembly.

[0067] See Figure 8 In one embodiment, the base 11 further has a mounting groove that connects to the mounting opening 115, and the limiting member 12 is disposed within the mounting groove. Thus, by adding a mounting groove structure to the base 11 that connects to the mounting opening 115, the limiting member 12 can be securely embedded within the mounting groove. This ensures both the effective sealing of the mounting opening 115 by the limiting member 12 and the reliable limiting of the guide portion 22. Furthermore, the groove positioning structure improves the accuracy and firmness of the limiting member 12 assembly, simplifying the assembly process while enhancing the overall structural stability and durability.

[0068] In one embodiment, the limiting member 12 is connected to the mounting base 1 by fasteners (not shown in the figure). Thus, by using fasteners to connect the limiting member 12 and the mounting base 1, the limiting member 12 is ensured to be firmly and reliably fixed, effectively preventing loosening and detachment during use, while also facilitating quick disconnection during disassembly and maintenance. This improves assembly flexibility and maintenance convenience while ensuring structural stability.

[0069] In one embodiment, the fastener can be a screw, bolt and nut assembly, rivet, etc.

[0070] In one embodiment, the mounting base 1 further includes a housing 13, which is sleeved on the base 11, and the snap-fit ​​protrusion 131 and the positioning groove 132 are both provided on the housing 13.

[0071] See Figures 5-6 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.

[0072] 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.

[0073] The mounting base 1 has a third flow channel 116. The upper end of the third flow channel 116 penetrates the end faces of the mounting base 1 and the bottom of the swinging component 2, which are arranged facing each other. The upper end of the third flow channel 116 connects to the second flow channel 24 and is sealed to the second flow channel 24. The other end of the third flow channel 116 penetrates the side wall of the mounting base 1 and is connected to the water supply source or water-using device. In this way, the filter element 3 and the swinging component 2 can be 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 116. 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, which can reduce the overall cost of the filter element mounting assembly.

[0074] See Figures 5-6 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.

[0075] 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 116 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 116 and the second flow channel 24 and prevent water leakage.

[0076] 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.

[0077] 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 116. 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.

[0078] 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.

[0079] 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.

[0080] In one embodiment, the mounting base 1 has locking grooves 111 on both opposite sides;

[0081] Locking portions 31 are provided on both opposite sides of the filter element 3, and the locking portions 31 cooperate with the corresponding locking grooves 111. In this way, the locking grooves 111 symmetrically arranged on both sides of the mounting base 1 cooperate with the corresponding locking portions 31 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.

[0082] Of course, in other embodiments, the number of locking grooves 111 and locking parts 31 can be one or more.

[0083] In one embodiment, the mounting base 1 has guide grooves 114 on both opposite sides;

[0084] Guide portions 22 are provided on both opposite sides of the swing component 2, and the guide portions 22 slide in engagement with the corresponding guide grooves 114. In this way, by sliding in engagement between the guide grooves 114 symmetrically arranged on both sides of the mounting base 1 and the guide portions 22 correspondingly arranged on both sides of the swing component 2, a bidirectional guiding structure is realized, which improves the stability and motion accuracy of the assembly, ensures that the swing component 2 slides smoothly along the predetermined trajectory, reduces the risk of deviation or jamming, and enhances the reliability and service life of the structure.

[0085] A preferred embodiment of this utility model provides a water purifier, including the above-mentioned filter cartridge mounting assembly.

[0086] The water purifier of this utility model, due to the adoption of the above-mentioned filter cartridge installation assembly, also uses the linkage design of the swinging component 2 and the locking structure. When installing the filter cartridge 3, the filter cartridge 3 is inserted at an angle onto the swinging component 2, so that the filter cartridge 3 can swing with the swinging component 2. Then, push the filter cartridge 3 to swing forward (in this embodiment, forward is to the right), so that the locking part 31 slides into the locking groove 111 to complete the locking. When it is necessary to remove the filter cartridge 3, push the filter cartridge 3 to swing in the opposite direction (in this embodiment, reverse is to the left), so that the locking part 31 exits the locking groove 111. Then, pull the filter cartridge 3 out of the swinging component 2 to unlock. The entire disassembly and assembly process only requires unidirectional push-pull and insertion / removal operations, without the need for rotation, which can reduce the operation intensity and improve the disassembly and assembly efficiency.
