Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more of the described features. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
In the present application, the term "exemplary" is used to mean "serving as an example, instance, or illustration. Any embodiment described as "exemplary" in this disclosure is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is presented to enable any person skilled in the art to make and use the application. In the following description, details are set forth for purposes of explanation. It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known structures and processes have not been described in detail so as not to obscure the description of the application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
The filter element assembly includes a filter element and a housing. The housing defines a filter cavity. The filter element is arranged in the filter cavity. The shell is provided with a water inlet terminal and a water outlet terminal. The water source water enters the filter cavity through the water inlet terminal, is filtered by the filter element and is discharged out of the filter cavity through the water outlet terminal.
In the prior art, the user assembles the filter element assembly into the adapted mounting structure at the time of replacement. When the filter element assembly is assembled to the base, the water inlet terminal is embedded into the water inlet pipe in the base, and the water outlet terminal is embedded into the water outlet pipe in the base. However, the existing installation structure does not have a self-checking and resetting function, so that a user cannot judge whether the filter element assembly is installed in place or not, and further bad phenomena such as water leakage and the like are easy to occur.
Therefore, the embodiment of the application provides a mounting structure of a filter element assembly. The installation structure can provide a self-checking function after replacing the filter element assembly so as to prompt a user whether the filter element assembly is successfully installed or not, thereby reducing the risk of water leakage and even avoiding the occurrence of water leakage caused by the fact that the filter element assembly is not assembled in place.
Specifically, referring to fig. 1, an installation structure according to an embodiment of the present application includes a bracket 10, a base 20, and an elastic mechanism 30.
Referring to fig. 1 or 7, the bracket 10 has a first receiving chamber S1 in which the cartridge assembly 40 is placed. Referring to fig. 2, upon mounting the cartridge assembly 40 to the mounting structure, the cartridge assembly 40 is at least partially received within the first receiving chamber S1. For example, the housing of the cartridge assembly 40 is positioned within the first receiving chamber S1.
Referring to fig. 1, base 20 has a second receiving cavity S2 in which cartridge assembly 40 is disposed. When the cartridge assembly 40 is mounted to the mounting structure, the water inlet and outlet ends of the cartridge assembly 40 are embedded in the second accommodation chamber S2, and at the same time, the water inlet terminal is embedded in the water inlet pipe 21 in the base 20, and the water outlet terminal is embedded in the water outlet pipe 22 in the base 20. And, the base 20 and the bracket 10 are connected to each other.
Referring to fig. 4, the elastic mechanism 30 is connected to the base 20, and the elastic mechanism 30 has a toggle rod 31 extending out of the base 20. The elastic mechanism 30 has a locked state. As shown in connection with fig. 3 and 4, with the spring mechanism 30 in the locked state, and with the spring mechanism 30 being able to secure the cartridge assembly 40 within the first receiving cavity S1 and within the second receiving cavity S2, the tap lever 31 abuts against the bracket 10. When the user assembles the filter element assembly 40 to the mounting structure, whether the elastic mechanism 30 fixes the filter element assembly 40 in the first accommodating cavity S1 and the second accommodating cavity S2 can be determined by determining whether the toggle rod 31 of the elastic mechanism 30 extending out of the base 20 abuts against the bracket 10. The resilient mechanism 30 is in a locked condition when the cartridge assembly 40 is properly assembled in place if and only if the tap lever 31 is abutted against the bracket 10. If the tap lever 31 cannot be abutted against the bracket 10, the elastic mechanism 30 cannot fix the filter element assembly 40 in the first accommodating cavity S1 and the second accommodating cavity S2, and the user can reassemble until the tap lever 31 is abutted against the bracket 10.
In one implementation of the assembly of the cartridge assembly 40 by this mounting structure: by applying an operation force to the toggle rod 31, so that the water inlet terminal of the filter element assembly 40 is embedded into the first pipe orifice 21a of the water inlet pipe 21 in the base 20, the water outlet terminal is embedded into the second pipe orifice 22a of the water outlet pipe 22 in the base 20, then the toggle rod 31 is released, the filter element assembly 40 is placed in the first accommodating cavity S1 and the second accommodating cavity S2, and whether the toggle rod 31 is abutted against the bracket 10 is judged at the moment; if so, the cartridge assembly 40 is assembled in place; if not, the cartridge assembly 40 is not assembled in place and the user needs to reassemble the cartridge assembly 40 until the tap lever 31 abuts the bracket 10.
It should be noted that the mounting structure further includes a cover plate 60. The base 20 defines a second receiving chamber S2 having an opening. The cover plate 60 is matched with the opening and covers the opening to close the second accommodating cavity S2. The base 20 is provided with positioning holes. The cover plate 60 is provided with a positioning column. The positioning column is embedded into the positioning hole. The cover plate 60 is constructed with holes for passing the water outlet terminal and the water inlet terminal.
It should be noted that, in some embodiments, the filter element assembly 40 may be placed in the first accommodating cavity S1 and the second accommodating cavity S2 simultaneously, and then determine whether the tap lever 31 abuts against the base 20; in this structure, the base 20 is fixedly connected with the bracket 10.
In other embodiments, the base 20 is rotatably coupled to the bracket 10. An embodiment of the present application is further illustrated, described and exemplified in the form of a base 20 in rotational connection with a stand 10. As shown in fig. 2, the base 20 has a first position. The housing of the cartridge assembly 40 is generally of a cylindrical configuration. The first receiving chamber S1 and the second receiving chamber S2 are coaxial when the base 20 is in the first position state, so that the cartridge assembly 40 can be placed in the first receiving chamber S1 and the second receiving chamber S2. As shown in fig. 7, the base 20 also has a second position state. As shown in fig. 7, when the base 20 is in the second position, the filter element assembly 40 is first placed in the second accommodating chamber S2, and the filter element assembly 40 is held on the base 20 by the elastic mechanism 30; progressively inserting the cartridge assembly 40 into the first housing chamber S1 in a rotating manner, the seat 20 being in a first position when the first housing chamber S1 and the second housing chamber S2 are in a coaxial condition, as shown in fig. 2, the cartridge assembly 40 being housed simultaneously in said first housing chamber S1 and in said second housing chamber S2; and when the base 20 rotates relative to the bracket 10 to gradually embed the filter element assembly 40 into the first accommodating cavity S1, the toggle rod 31 will rotate relative to the bracket 10 along with the base 20, and after the filter element assembly 40 is assembled into the first accommodating cavity S1, it is determined whether the toggle rod 31 abuts against the base 20. If so, as shown in FIG. 4, the cartridge assembly 40 is assembled in place; if not, the cartridge assembly 40 is not assembled in place and the user needs to reassemble the cartridge assembly 40 until the tap lever 31 abuts the bracket 10.
Further, in the prior art, the bracket 10 is generally suspended at one end, so that there is a risk of the filter element assembly 40 being axially pushed out of the base 20 under the action of the water pressure on the filter element assembly 40, and for this purpose, as shown in fig. 1, the mounting structure further includes an elastic member 50. As shown in fig. 1, the elastic member 50 is disposed at an end of the bracket 10 away from the base 20 and is located in the first accommodating cavity S1. As shown in fig. 2, the spring member 50 is configured to abut the cartridge assembly 40 when the base 20 is in the first position to provide a first axial force to the cartridge assembly 40. The elastic member 50 can resist water pressure based on deformation thereof, so as to avoid sealing failure between the filter element assembly 40 and the water pipe of the base 20 caused by the influence of the water pressure of the filter element assembly 40, and reduce the risk of water leakage. Moreover, the spring 50 is capable of providing a first axial force to the cartridge assembly 40, effectively reducing the risk of the cartridge assembly 40 falling out during shipment due to shaking.
Also in this embodiment, when the filter element assembly 40 is mounted to the first accommodating chamber S1, the filter element assembly 40 is gradually embedded in the first accommodating chamber S1 following the base 20, the filter element assembly 40 is gradually contacted with the elastic member 50, and the first axial force provided by the elastic member 50 is gradually parallel to the axis of the filter element assembly 40; if the filter element assembly 40 is not assembled in place during installation, the toggle rod 31 cannot abut against the support 10, the first axial force has an included angle with the axis of the filter element assembly 40, and the filter element assembly 40 is at risk of being ejected, so that whether the filter element assembly 40 is assembled in place in the axial direction can be judged by observing whether the toggle rod 31 abuts against the support 10. Thus, providing the spring 50 at the end of the bracket 10 remote from the base 20 can also effectively increase the reliability of the axial positioning of the cartridge assembly 40.
In some embodiments, the resilient member 50 is configured as a resilient rib or tab. There is a gap between the end of the cartridge assembly 40 and the end of the bracket 10. The spring member 50 is typically in its original state with a length extending beyond the end of the carrier 10 that is between 0.1mm and 0.3mm greater than the gap, such that the spring member 50 can abut the cartridge assembly 40 and be compressed by the assembly force to deform to provide a first axial force to the cartridge assembly 40. The elastic member 50 may be made of plastic or metal sheet.
As an alternative to the above-described embodiment, the side walls of the support 10, which are disposed opposite each other, are each provided with a first coupling opening 11 which communicates with the first receiving space S1 and a second coupling opening 12 which communicates with the first receiving space S1. The base 20 is provided with a water inlet pipe 21 and a water outlet pipe which are coaxially arranged, the water inlet pipe 21 is arranged in the first hanging connector 11, and the water outlet pipe is arranged in the second hanging connector 12, so that the base 20 can rotate relative to the bracket 10. In particular embodiments, the base 20 rotates. Specifically, the water inlet pipe 21 extends out of the bracket 10 from the first accommodating chamber S1 through the first hanging connector 11, and can be communicated with the water inlet side (water source); the water outlet pipe 22 extends out of the bracket 10 from the second accommodating cavity S2 through the second hanging connector 12 so as to be communicated with the water side. The stand 10 supports a water inlet pipe 21 through a first hooking joint 11 and a water outlet pipe through a second hooking joint 12. As shown in fig. 1, the first and second hooking interfaces 11 and 12 are each configured as a hooking shape. When the filter element assembly 40 is installed, the filter element assembly 40 is installed in the base 20, then the water inlet pipe 21 is installed in the first hanging connector 11, the water outlet pipe 22 is installed in the second hanging connector 12, and then the force is applied to the filter element assembly 40 or the base 20 to drive the base 20 to rotate around the axes of the water inlet pipe 21 and the water outlet pipe 22 to approach the first accommodating cavity S1 of the bracket 10 until the base 20 is in the first position state.
In some embodiments, when the filter element assembly 40 is replaced, the fixing constraint between the water inlet side and the water inlet pipe 21 of the water purifier and the fixing constraint between the water outlet side and the water outlet side of the water purifier need to be released. After the unused cartridge assembly 40 or the cleaned cartridge assembly 40 is installed in place, the inlet tube 21 is then secured to and in communication with the water side, outlet tube 22 and water side.
As an alternative to the above embodiment, the bracket 10 is configured with a limiting portion. With the elastic mechanism 30 in the locked state, and when the elastic mechanism 30 can fix the filter element assembly 40 in the first accommodating cavity S1 and the second accommodating cavity S2, the toggle rod 31 abuts against the limiting portion. The stop is located at a precise location on the support 10. In particular, the exact location of the stop is set by the practitioner according to the relative position of the base 20 and the bracket 10 and the length of the dial, so that the filter cartridge assembly 40 can rest against the stop after it is in place. The stopper portion may be constructed in a planar structure as shown in fig. 4. The stop may also be a groove formation or boss (neither shown) or the like on the bracket 10.
As an alternative to the above-described embodiment, the tap lever 31 has a first section 311 and a second section 312 connected to each other. The first section 311 is located outside the base 20. The first section 311 may abut against the bracket 10 when the elastic mechanism 30 is in the locked state. The second section 312 is located within the base 20. The second section 312 has a first locking feature 312a configured thereon, the first locking feature 312a being adapted to a second locking feature 40a on the cartridge assembly 40. As shown in fig. 6, the first locking structure 312a is hook-shaped. The second locking structure 40a on the cartridge assembly 40 is generally convex and integrally disposed on the outside wall of the water inlet or outlet terminal. The first locking structure 312a is engageable with the second locking structure 40a when the resilient mechanism 30 is in the locked condition to provide a second axial force to the cartridge assembly 40 for restricting the water inlet and outlet terminals of the cartridge assembly 40 from exiting the corresponding water inlet and outlet tubes 21, 22. Moreover, since the water pressure on the water inlet side has a certain fluctuation, the elastic member 50 for providing the first axial force to the filter element assembly 40 is arranged on the bracket 10, and the elastic member 50 has elasticity, so that the deformation amount can be adaptively changed according to the fluctuation of the water pressure, and the first axial force is variable, so that the second axial force can be changed along with the first axial force, the first locking structure 312a and the second locking structure 40a are prevented from generating severe collision when the water pressure fluctuates, the service lives of the first locking structure 312a and the second locking structure 40a are prolonged, the locking effect of the elastic mechanism 30 can be further improved, and the water leakage risk is reduced. Moreover, since the first axial force can act to limit axial movement of the cartridge assembly 40, the second axial force between the first locking structure 312a and the second locking structure 40a can be smaller, and deformation or even failure fracture of the water inlet or outlet terminals due to long-time compression can be avoided.
As an alternative to the above embodiment, as shown in fig. 8, the elastic mechanism 30 has an unlocked state. In the unlocked state, a user can remove the cartridge assembly 40 from the mounting structure or install the cartridge assembly 40 into the base 20. The elastic mechanism 30 further includes an elastic member 32, and two ends of the elastic member 32 are respectively connected to the base 20 and the second section 312.
In a specific implementation, the middle portion of the second section 312 has a circular arc structure. The second locking structure 40a is provided to the circular arc structure. The second section 312 is further provided with a connecting post, which is connected to the circular arc structure and is located radially outside the circular arc structure. The connecting post is fixedly connected to the elastic member 32. The elastic member 32 is fixedly connected with the base 20. The elastic member 32 may be a spring or other element having a deformation capability. In the embodiment of the present application, the elastic member 32 is preferably a spring.
In a specific implementation process, the circular arc structure is matched with any one of the water inlet terminal or the water outlet terminal, so that the circular arc structure can be tightly attached to the outer side wall of the water inlet terminal or the water outlet terminal when the elastic mechanism 30 is in a locking state.
Further, the second section 312 is rotatably connected to the base 20 to enable the tap lever 31 to rotate between a normal position and a trigger position. In general, in order to save effort during unlocking, the end of the second section 312 remote from the first section 311 is provided with a first rotational connection 312b. The base 20 is provided with a second rotation connection portion 23 adapted to the first rotation connection portion 312b. For example, the first rotating connection portion 312b is a hole-like structure (such as a through hole), and the second rotating connection portion 23 is a cylinder structure adapted to the hole-like structure. For another example, the first rotating connection portion 312b is a cylindrical structure, and the second rotating connection portion 23 is a hole structure (such as a through hole) adapted to the cylindrical structure.
As shown in fig. 4, when the toggle lever 31 is in the normal position, the elastic member 32 is in the first elastic state, and the elastic mechanism 30 is in the locked state. The resilient mechanism 30 limits the cartridge assembly 40 from large axial displacement. As shown in fig. 8, when the tap lever 31 is in the trigger position, the elastic member 32 is in the second elastic state, and the elastic mechanism 30 is in the unlocked state, where the filter element assembly 40 can be removed from the base 20 or the filter element assembly 40 can be mounted into the base 20.
It should be noted that the elastic state of the elastic member 32 can be understood in a broad sense. For example, when the elastic member 32 is in an unstressed state, the elastic member 32 is in an elastic state with a deformation amount of 0. In the embodiment of the present application, when the elastic member 32 is in the first elastic state, the elastic member 32 has a first deformation amount. While when the elastic member 32 is in the second elastic state, the application of force F to the first section 311 needs to rotate the tap lever 31, so that the elastic member 32 is required to deform in the x-direction, and thus, in general, the first deformation amount of the elastic member 32 in the first elastic state is smaller than the second deformation amount of the elastic member 32 in the second elastic state. Typically, the first amount of deformation is 0, i.e., the first locking structure 312a mates with the second locking structure 40a when the spring is at its original length. When the toggle rod 31 is at the triggering position, the toggle rod 31 compresses the spring to deform the spring, and at this time, the first locking structure 312a is separated from the matching relationship with the second locking structure 40a when the toggle rod 31 rotates.
As an alternative to the above embodiments, to facilitate installation of the cartridge assembly 40 and to enhance the locking effect of the cartridge assembly 40 during use. As shown in fig. 7, the base 20 has a second position, and when the base 20 is in the second position, the axis of the first accommodating cavity S1 and the axis of the second accommodating cavity S2 form an acute angle, and at this time, the toggle rod 31 is disengaged from the bracket 10. At this point, the spring 32 may be compressed by operating the first section 311 such that the first locking structure 312a disengages from the second locking structure 40a, thereby unlocking the cartridge assembly 40. Specifically, in the embodiment of the present application, as shown in fig. 8, when an external force is applied to the first section 311 to drive the first section 311 to move close to the bracket 10, the toggle rod 31 moves from the normal position to the trigger position, and compresses the elastic member 32, so that the elastic mechanism 30 is in the unlocked state. That is, when unlocked, an external force applied to the first section 311 is required to have a component directed to the bracket 10 by the first section 311 in order to compress the elastic member 32.
Namely: referring to fig. 4, after the cartridge assembly 40 is mounted in place, the cartridge assembly 40 cannot be unlocked by an external force when the tap lever 31 is in contact with the bracket 10. At this time, since the resistance of the elastic member 32 needs to be overcome at the time of unlocking, the elastic member 32 is compressed; the user applies only a force to the tap lever 31 perpendicular to the holder 10 and the direction of this force is directed by the tap lever 31 towards the holder 10. However, when the user applies a force directed to the bracket 10 by the tap lever 31 due to the contact between the tap lever 31 and the bracket 10, the tap lever 31 cannot rotate and cannot compress the elastic member 32, and thus cannot unlock. Thus, after the cartridge assembly 40 is installed in place, the tap lever 31 contacts the bracket 10 and the installation mechanism is in a self-locking state. The locking of the filter element assembly 40 by the elastic mechanism 30 can only be released after the toggle rod 31 is out of contact with the bracket 10. Therefore, the mounting structure can effectively keep the filter element assembly 40 fixed after the filter element assembly 40 is mounted in place, improves the reliability of the filter element assembly 40 used after replacement, and effectively prevents water leakage in the use process.
Specifically, the base 20 may be in a plurality of second position states. Generally, the position of base 20 when cartridge assembly 40 is completely disengaged from spring 50 may be the second position. At this point, the cartridge assembly 40 is conveniently removed from the base 20 and the cartridge assembly 40 is conveniently installed into the base 20 because the first axial force need not be overcome when removing the cartridge assembly 40 from the base 20 or installing the cartridge assembly 40 into the base 20.

providing a cartridge assembly 40 and a mounting structure for the cartridge assembly 40; the cartridge assembly 40 mounting structure employs some or all of the foregoing embodiments;

if not, the position of the filter element assembly 40 in the first accommodating cavity S1 and the second accommodating cavity S2 is adjusted until the toggle rod 31 abuts against the bracket 10, and/or the elastic mechanism 30 is adjusted so that the toggle rod 31 abuts against the bracket 10, so that the elastic mechanism 30 is in the locking state.
The mounting method of the filter element assembly 40 provided by the embodiment of the application can reduce the water leakage risk and even prevent the water leakage caused by the fact that the filter element assembly 40 is not assembled in place.
