Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and more specifically, to a quick-release structure for a water purifier filter cartridge. Furthermore, this utility model also relates to a parallel central water purifier including the aforementioned quick-release structure for the water purifier filter cartridge. Background Technology

[0002] A central water purifier is the first stage of purification for all the water used in a house. It can filter out sediment, rust, and large particles from tap water. It prevents the large amount of sediment and impurities generated in the urban and residential water supply network from causing harm to the human body, and also plays a positive role in protecting concealed pipes, faucets, plumbing, water heaters, boilers, central air conditioning, washing machines, dishwashers, coffee machines, and other water appliances (water purifiers, reverse osmosis systems, water softeners).

[0003] Current central water purifiers use PP cotton or carbon fiber composite filter rods as their filter cartridges, which have a very limited lifespan. The filter cartridges turn black and discolor within six months to a year, and the water output decreases. In areas with poor water quality, the filter cartridges are easily clogged, and the lifespan may even be less than six months. Moreover, flushing cannot restore the filter cartridges, affecting the lifespan of the machine and the user experience. Therefore, the filter cartridge assembly needs to be replaced regularly. Most existing filter cartridge assemblies are wrapped in filter cartridges, and the filter cartridges are connected to the main unit of the water purifier via threads. When replacing them, special tools are required, making filter cartridge replacement difficult and requiring professional operation, which affects the user experience.

[0004] In conclusion, how to solve the problem of difficult replacement of water purifier filter cartridges is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a quick-release structure for a water purifier filter cartridge. By combining the receiving cavity and locking module in the mounting base, the filter cartridge assembly can be quickly assembled. Moreover, no special tools are required during assembly and disassembly, reducing the difficulty of replacing the filter cartridge assembly. Users can disassemble and assemble it themselves, improving the user experience.

[0006] Another objective of this utility model is to provide a parallel central water purifier that includes the above-mentioned quick-release filter cartridge structure, has the same technical features, and can solve the same technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A quick-release structure for a water purifier filter cartridge, used for the installation and fixation of the filter cartridge assembly;

[0009] The quick-release structure of the water purifier filter cartridge includes:

[0010] Mounting base, including a receiving cavity, for mounting and radially fixing the filter cartridge assembly;

[0011] The quick-release assembly includes a locking module and a drive module. The locking module is slidably mounted relative to the mounting base, and the sliding direction is consistent with the radial direction of the filter cartridge assembly. The locking module includes a protruding edge that can be inserted into a slot on the outer periphery of the filter cartridge assembly for axially fixing the filter cartridge assembly. The drive module is provided with a transmission component for driving the locking module to slide relative to the mounting base. The transmission component and / or the drive module are provided with a self-locking structure.

[0012] Preferably, the transmission assembly includes a guide groove and a slider that slide relative to each other;

[0013] The guide groove is fixed relative to the drive module, and the drive module is slidably mounted relative to the mounting base;

[0014] The slider is fixed relative to the locking module;

[0015] When the guide groove slides relative to the slider, it can drive the locking module to slide relative to the mounting base.

[0016] Preferably, the relative sliding direction of the guide groove and the slider is at an angle to the sliding direction of the drive module, and the angle is smaller than the self-locking angle of the relative sliding of the slider and the guide groove.

[0017] Preferably, the guide groove includes a first straight groove, an inclined groove, and a second straight groove connected in sequence. The relative sliding directions of the first straight groove and the second straight groove with the slider and the sliding direction of the drive module are both at an angle, and the angle is less than the self-locking angle of the relative sliding of the slider with the guide groove.

[0018] Preferably, the length directions of the first straight slot and the second straight slot are consistent with the sliding direction of the drive module;

[0019] The sliding direction of the drive module is perpendicular to the sliding direction of the locking module.

[0020] Preferably, the drive module includes a limiting protrusion connected by an elastic element, wherein the compression direction of the elastic element is perpendicular to the sliding direction of the drive module;

[0021] The mounting base includes a limiting groove;

[0022] When the drive module slides to the preset position, the limiting protrusion can engage in the limiting groove.

[0023] Preferably, the quick-release assembly further includes a plurality of brackets, the brackets being fixedly connected to the mounting base, and the quick-release assembly being accommodated between the brackets and the mounting base.

[0024] A parallel central water purifier includes the quick-release filter cartridge structure, water circuit assembly, and several sets of filter cartridge assemblies as described in any one of the above-mentioned items.

[0025] The water system assembly includes interconnected main water channels and several valve heads;

[0026] The filter cartridge assembly includes an end cap, which is coaxially mounted in the receiving cavity. The end cap includes an end that is inserted into the valve head. An insertion groove is provided on the outer periphery of the end cap, and the outer wall of the valve head is provided with a valve head groove. A protruding edge can pass through the valve head groove and be inserted into the insertion groove.

[0027] Preferably, the top of the end cap is provided with a raised rib;

[0028] The drive module includes a receiving groove. When the end cap is installed in the receiving cavity, the rib is relatively movably received in the receiving groove. When the drive module moves to its own stroke end point, the side wall of the receiving groove abuts against the rib and brakes.

[0029] Preferably, the main waterway includes an inlet channel and an outlet channel, and a flow meter is installed in the outlet channel to detect the flow rate in the outlet channel.

[0030] The parallel central water purifier provided by this utility model includes the above-mentioned quick-release structure for the water purifier filter cartridge, and compared with the prior art, it has at least the following beneficial effects:

[0031] 1. A receiving cavity is provided in the mounting base to accommodate the filter cartridge assembly and to limit the radial movement of the filter cartridge assembly. At the same time, the locking module in the quick-release assembly is slidably installed with the mounting base, and the sliding direction is consistent with the radial movement of the filter cartridge assembly. When the protruding edge of the locking module is inserted into the insertion groove of the filter cartridge assembly, the axial movement of the filter cartridge assembly by the locking module is completed. Combined with the radial movement of the filter cartridge assembly by the receiving cavity, the filter cartridge assembly is locked, realizing the quick installation of the filter cartridge assembly.

[0032] When the filter cartridge assembly needs to be replaced, simply slide the locking module in the reverse direction to disengage the protruding edge from the insertion slot, thereby releasing the axial restriction on the filter cartridge assembly. The filter cartridge assembly can then be pulled out axially for replacement. The entire replacement process is simple and can be done by the user, which improves the user experience.

[0033] 2. The quick-release assembly also includes a drive module that drives the locking module to slide, and the transmission component or drive mechanism between the drive module and the locking module is equipped with a self-locking mechanism. That is, after the locking module completes the axial limiting of the filter cartridge assembly, the drive mechanism can limit the locking module to prevent the locking module from releasing the axial limiting of the filter cartridge assembly on its own, thus ensuring the installation stability of the filter cartridge assembly during use.

[0034] The parallel central water purifier provided by this utility model includes the above-mentioned quick-release structure for the water purifier filter cartridge and has the same beneficial effects. Attached Figure Description

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0057] The core of this utility model is to provide a quick-release structure for a water purifier filter cartridge. By combining the receiving cavity and locking module in the mounting base, the filter cartridge assembly can be quickly assembled. Moreover, no special tools are required for disassembly and assembly, reducing the difficulty of replacing the filter cartridge assembly. Users can disassemble and assemble it themselves, improving the user experience.

[0058] Another core aspect of this utility model is to provide a parallel central water purifier that includes the above-mentioned quick-release filter cartridge structure, which has the same technical features and can solve the same technical problems.

[0059] Please refer to Figures 1-11 A quick-release structure for a water purifier filter cartridge, used for the installation and fixing of the filter cartridge assembly 4;

[0060] The quick-release structure of the water purifier filter cartridge includes:

[0061] Mounting base 1 includes receiving cavity 16 for mounting and radially fixing filter cartridge assembly 4;

[0062] The quick-release assembly 2 includes a locking module 21 and a drive module 22. The locking module 21 is slidably mounted relative to the mounting base 1, and the sliding direction is consistent with the radial direction of the filter cartridge assembly 4. The locking module 21 includes a protruding edge 212 that can be inserted into the insertion groove 412 on the outer periphery of the filter cartridge assembly 4 for axially fixing the filter cartridge assembly 4. The drive module 22 is provided with a transmission component for driving the locking module 21 to slide relative to the mounting base 1. The transmission component and / or the drive module 22 are provided with a self-locking structure.

[0063] like Figure 2 As shown, the filter cartridge assembly 4 includes an end cap 41 and a cylinder 42. The end cap 41 and the cylinder 42 form a closed cavity. The filter element 43 is assembled in the cavity formed by the end cap 41 and the cylinder 42. The end cap 41 is provided with an end head 411 for connecting the water circuit assembly 3, and the end head 411 is provided with a plug groove 412.

[0064] In some embodiments, the insertion groove 412 is provided on the outer peripheral wall of the end cap 41 and / or the cylinder 42.

[0065] like Figure 2 and Figure 3 As shown, a receiving cavity 16 is provided at the bottom of the mounting base 1, and the end cap 41 and / or filter cartridge assembly 4 can be snapped into the receiving cavity 16 to achieve radial positioning of the filter cartridge assembly 4;

[0066] The locking module 21 is slidably installed on the mounting base 1, and the sliding direction is consistent with the radial direction of the filter cartridge assembly 4. The protruding edge 212 of the locking module 21 can engage with the insertion groove 412, thereby realizing the axial limit of the filter cartridge assembly 4, that is, the relative position of the filter cartridge assembly 4 and the mounting base 1 is locked. When replacing the filter cartridge assembly 4, it is only necessary to slide the locking module 21 in the opposite direction to disengage the protruding edge 212 from the insertion groove 412, thereby releasing the axial limit of the filter cartridge assembly 4. The filter cartridge assembly 4 can then be pulled out of the receiving cavity 16 along the axial direction to complete the replacement of the filter cartridge assembly 4. The operation is simple and easy for users to complete by themselves, which helps to improve the user experience.

[0067] In some embodiments, such as Figure 3 and Figure 4 As shown, the top of the receiving cavity 16 is provided with a first mounting hole 13 for the end cap 411 to pass through. The locking module 21 and the receiving cavity 16 are located on opposite sides of the mounting base 1. When the filter cartridge assembly 4 is snapped into the receiving cavity 16, the end cap 411 passes through the first mounting hole 13, and the protruding edge 212 is inserted into the insertion groove 412 located at the end cap 411. This allows the top wall of the receiving cavity 16 to axially limit the filter cartridge assembly 4 in one direction, while the locking module 21 only needs to axially limit the filter cartridge assembly 4 in the other direction.

[0068] Meanwhile, the sliding power of the locking module 21 is provided by the drive module 22. A transmission component with a self-locking structure is provided between the drive module 22 and the locking module 21, that is, the locking module 21 can only be driven to slide by the drive module 22 and cannot be driven in the opposite direction. This ensures that the locking module 21 can have a relatively stable positional relationship during use, thus ensuring the stable installation and locking of the filter cartridge assembly 4.

[0069] And / or, the drive module 22 itself has a self-locking structure. When it drives the locking module 21 to the locking position, the self-locking structure can lock the position of the drive module 22, thereby preventing the locking module 21 from moving to the non-locking position and preventing the locking module 21 from releasing the lock on the filter cartridge assembly 4.

[0070] In some embodiments, the transmission assembly includes a guide groove 221 and a slider 211 that slide relative to each other;

[0071] The guide slot 221 is fixed relative to the drive module 22, and the drive module 22 is slidably mounted relative to the mounting base 1.

[0072] The slider 211 is fixed relative to the locking module 21;

[0073] When the guide groove 221 slides relative to the slider 211, it can drive the locking module 21 to slide relative to the mounting base 1.

[0074] like Figure 4As shown, the mounting base 1 is provided with a first guide component 11 and a second guide component 12, which are used for the sliding installation of the drive module 22 and the locking module 21, respectively. There is a non-zero included angle between the first guide component 11 and the second guide component 12, so the sliding direction of the locking module 21 and the drive module 22 also has a non-zero included angle.

[0075] The first guide component 11 is a slide groove design, and the bottom of the drive module 22 is provided with guide ribs 224, which are slidably disposed in the slide groove. The second guide component 12 is a slide rail composed of baffles on both sides, and the locking module 21 is slidably installed in the slide rail.

[0076] like Figure 5 , Figure 6 and Figure 7 As shown, the locking module 21 includes a slider 211 and the driving module 22 includes a guide groove 221. The slider 211 and the guide groove 221 are slidably installed. When the driving module 22 slides, the slider 211 and the guide groove 221 slide relative to each other, driving the locking module 21 to slide, that is, driving the protrusion 212 to insert or pull out of the insertion groove 412.

[0077] In some embodiments, the transmission component may adopt a linkage mechanism, that is, the movement of the drive module 22 is transmitted to the locking module 21 through the linkage mechanism, which drives the locking module 21 to slide radially along the filter cartridge assembly 4, so as to realize the insertion or removal of the protrusion 212 and the insertion groove 412.

[0078] In some embodiments, the relative sliding direction of the guide groove 221 and the slider 211 forms an angle with the sliding direction of the drive module 22, and the angle is smaller than the self-locking angle of the relative sliding of the slider 211 and the guide groove 221.

[0079] By setting the angle between the length direction of the guide groove 221 and the sliding direction of the drive module 22, the slider 211 and the guide groove 221 can be self-locked during sliding. That is, the guide groove 221 can only be driven to slide by the sliding of the drive module 22, which in turn drives the relative sliding of the slider 211 and the guide groove 221. The relative sliding of the slider 211 and the guide groove 221 cannot drive the sliding of the drive module 22. In other words, the self-locking between the slider 211 and the guide groove 221 enables the drive module 22 to drive the locking module 21 in one direction.

[0080] In some embodiments, the guide groove 221 includes a first straight groove, an oblique groove, and a second straight groove connected in sequence. The relative sliding directions of the first straight groove and the second straight groove with the slider 211 are both at an angle to the sliding direction of the drive module 22, and the angle is less than the self-locking angle of the relative sliding of the slider 211 with the guide groove 221.

[0081] like Figure 5 and Figure 6As shown, the guide groove 221 adopts a three-section structure. The first and second straight slots have self-locking capabilities. For example, the relative sliding direction of the first and second straight slots and the slider 211 is perpendicular to the sliding direction of the locking module 21. When the slider 211 is in the first and second straight slots, it can drive the locking module 21 to slide, but cannot drive it in the opposite direction. When the slider 211 is in the first and second straight slots, the protrusion 212 is in the position of being fully inserted into or fully pulled out of the insertion slot 412. That is, the locking module 21 achieves axial limiting and complete release of the limiting on the filter cartridge assembly 4, thus realizing the self-locking of the locking module 21 at the end of the stroke.

[0082] In some embodiments, the length direction of the first straight slot and the second straight slot is consistent with the sliding direction of the drive module 22;

[0083] The sliding direction of the drive module 22 is perpendicular to the sliding direction of the locking module 21.

[0084] like Figure 5 As shown, when the slider 211 slides to the position of the first straight slot and the second straight slot, the relative sliding direction of the slider 211 and the guide groove 221 is perpendicular to the sliding direction of the locking module 21, so the locking module 21 can be self-locked at this time.

[0085] In some embodiments, the drive module 22 includes a limiting protrusion 223 connected by an elastic member, wherein the compression direction of the elastic member is perpendicular to the sliding direction of the drive module 22.

[0086] Mounting base 1 includes a limiting groove 15;

[0087] When the drive module 22 slides to the preset position, the limiting protrusion 223 can be engaged in the limiting groove 15.

[0088] like Figure 5 As shown, a limiting protrusion 223 is provided on the side of the drive module 22. When the drive module 22 drives the locking module 21 to move to the end of the stroke, the limiting protrusion 223 can be engaged in the limiting groove 15 of the mounting base 1 to lock the position of the drive module 22. By locking the position of the drive module 22, the position of the locking module 21 is locked.

[0089] In some embodiments, a self-locking component is directly provided between the locking module 21 and the mounting base 1. For example, the locking module 21 is provided with an auxiliary limiting protrusion, and the mounting base 1 is provided with an auxiliary limiting groove. When the locking module 21 moves to a preset stroke point, the auxiliary limiting protrusion can be engaged in the auxiliary limiting groove, thereby locking the locking module 21 at the preset stroke point.

[0090] In some embodiments, the drive module 22 has a U-shaped structure, with a pull handle 222 in the middle for easy pulling by the user, and drive parts on both sides to drive the two sets of locking modules 21 to move towards or away from each other, so that the protruding edge 212 can be inserted into the insertion slot 412 from different directions. In some embodiments, multiple insertion slots 412 are combined into an annular groove coaxial with the filter cartridge assembly 4, so that the filter cartridge assembly 4 is not subject to the installation angle design during installation, and can be installed at any angle to meet the insertion angle requirements of the protruding edge 212 and the insertion slot 412.

[0091] In some embodiments, the contact surface between the protruding edge 212 and the side wall of the insertion groove 412 is a wedge-shaped surface. As the insertion depth of the protruding edge 212 increases, the positive pressure between the protruding edge 212 and the side wall of the insertion groove 412 increases, so as to reduce the axial movement margin of the filter cartridge assembly 4 and ensure its stability after installation.

[0092] like Figure 1 As shown, the driving part of the driving module 22 has a hollow structure, and the locking module 21 is housed in the hollow structure of the driving part, which can effectively prevent the locking module 21 from being accidentally activated and thus releasing the axial locking of the filter cartridge assembly 4.

[0093] In some embodiments, the quick-release assembly 2 further includes a plurality of brackets 5, which are fixedly connected to the mounting base 1, and the quick-release assembly 2 is accommodated between the brackets 5 and the mounting base 1.

[0094] like Figure 1 and Figure 4 As shown, the mounting base 1 is provided with several threaded holes for mounting the bracket 5. The quick-release component 2 is accommodated between the bracket 5 and the mounting base 1, effectively preventing the quick-release component 2 from detaching from the mounting base 1.

[0095] In addition to the quick-release structure of the water purifier filter cartridge disclosed in the above embodiments, this utility model also provides a parallel central water purifier, including any of the above quick-release structure of the water purifier filter cartridge, water circuit assembly 3 and several sets of filter cartridge assemblies 4.

[0096] Water circuit component 3 includes an interconnected main water channel 31 and several valve heads 32;

[0097] The filter cartridge assembly 4 includes an end cap 41, which is coaxially mounted in the receiving cavity 16. The end cap 41 includes an end 411 that is inserted into the valve head 32. An insertion groove 412 is provided on the outer periphery of the end 411, and a valve head groove 321 is provided on the outer wall of the valve head 32. The protruding edge 212 can pass through the valve head groove 321 and be inserted into the insertion groove 412.

[0098] like Figure 1 , Figure 2 , Figure 8 and Figure 9As shown, the water circuit assembly 3 includes a main water channel 31 and several valve heads 32 connected in parallel on the main water channel 31. The valve heads 32 are fixedly connected to and connected to the end 411, thereby realizing the connection between the filter cartridge assembly 4 and the water circuit assembly 3.

[0099] The valve head 32 and the end 411 are connected by a coaxial sleeve. The valve head 32 is provided with a through valve head groove 321, and the protruding edge 212 can pass through the valve head groove 321 and be inserted into the insertion groove 412. That is, the protruding edge 212 can also realize the axial limit of the valve head 32 and the end 411, so as to prevent the end 411 from accidentally separating from the valve head 32.

[0100] In practical applications, by connecting several valve heads 32 and filter cartridge assemblies 4 one by one, multiple filter cartridge assemblies 4 are arranged in parallel in the water circuit. Multiple filter cartridge assemblies 4 filter the water flow at the same time, increasing the total amount of water filtered per unit time. Furthermore, by increasing the number of filter cartridge assemblies 4, the amount of water filtered by a single filter cartridge assembly 4 per unit time is reduced, thereby extending the service life of the filter cartridge assembly 4.

[0101] In some embodiments, such as Figure 1 As shown, a second mounting hole 14 is provided on the side of the mounting base 1 for through-fixing of the water circuit assembly 3, so as to improve the overall relative positional stability of the water circuit assembly 3, the mounting base 1 and the filter cartridge assembly 4.

[0102] In some embodiments, the top of the end cap 41 is provided with a rib 413;

[0103] The drive module 22 includes a receiving groove 225. When the end cover 41 is installed in the receiving cavity 16, the protruding rib 413 is relatively movably received in the receiving groove 225. When the drive module 22 moves to its own stroke end point, the side wall of the receiving groove 225 abuts against the protruding rib 413 and brakes.

[0104] like Figure 10 and Figure 11 As shown, a rib 413 is provided on the top of the end cap 41;

[0105] like Figure 6 As shown, the drive module 22 has a receiving groove 225 on its side. When the filter cartridge assembly 4 is installed, the protruding rib 413 can be engaged in the receiving groove 225. When the drive module 22 moves to the end of its stroke, the side wall of the receiving groove 225 will abut against the protruding rib 413, thereby restricting the movement of the drive module 22. That is, when the filter cartridge assembly 4 is installed, the maximum stroke of the drive module 22 can be restricted, preventing the drive module 22 from detaching from the mounting base 1.

[0106] In some embodiments, the main water channel 31 includes an inlet channel and an outlet channel, and a flow meter 33 is installed in the outlet channel to detect the flow rate in the outlet channel.

[0107] like Figure 2 , Figure 8 and Figure 9 As shown, a flow meter 33 is installed in the water outlet channel to detect the water output of the central water purifier. When the water output is less than the minimum value of the preset range, it indicates that the filter cartridge assembly 4 is severely clogged, prompting the replacement of the filter cartridge assembly 4.

[0108] like Figure 12 , Figure 13 and Figure 14 As shown, the water flows through the inlet channel and the corresponding valve head 32 and is diverted to different filter cartridge assemblies 4. The diverted water flows through the inlet end 411 of the filter cartridge assembly 4 and enters the inside of the cylinder 42. It is filtered from the outside to the inside along the radial direction of the filter element 43. Then, it flows through the outlet end 411 of the filter cartridge assembly 4 and the valve head 32 and converges into the outlet channel to complete the water discharge.

[0109] like Figure 1 As shown, several filter cartridge assemblies 4 of this parallel central water purifier are arranged horizontally, and the sliding direction of the locking module 21 in the quick-release assembly 2 is consistent with the arrangement direction of the filter cartridge assemblies 4. The sliding direction of the drive module 22 is perpendicular to the arrangement direction of the filter cartridge assemblies 4, thereby reducing the probability of accidental contact of the locking module 21 and improving the ease of operation of the drive module 22.

[0110] The structure of the other parts of this parallel central water purifier is described in reference to existing technologies and will not be repeated here.

[0111] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
