It will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and processes are not shown in detail to avoid obscuring the description of the invention with unnecessary detail. Thus, the present invention 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 housing is configured with a water inlet terminal and a water outlet terminal. Water from the water source enters the filtering cavity through the water inlet terminal and is discharged out of the filtering cavity through the water outlet terminal after being filtered by the filter element.
In the prior art, the user assembles the filter element assembly into a fitted mounting structure during replacement. When assembling filter element group spare to base, in the inlet pipe in the inlet terminal embedding base, in the outlet pipe in the outlet terminal embedding base. However, the existing mounting structure does not have the self-checking reset function, so that a user cannot judge whether the filter element assembly is mounted in place, and further, the undesirable phenomena such as water leakage and the like are easy to occur.
To this end, the embodiment of the application provides a mounting structure of a filter element assembly. This mounting structure can provide the self-checking function after changing filter element group spare to whether suggestion user filter element group spare is installed successfully, thereby reduce the emergence of the condition of leaking that the assembly of stopping even leads to because of filter element group spare does not put in place.
Specifically, referring to fig. 1, an embodiment of the present application provides a mounting structure including a bracket 10, a base 20, and an elastic mechanism 30.
Referring to fig. 1 or 7, the holder 10 has a first receiving cavity S1 in which the filter element assembly 40 is placed. Referring to fig. 2, the filter cartridge assembly 40 is at least partially received within the first receiving cavity S1 when the filter cartridge assembly 40 is mounted to the mounting structure. For example, the housing of the filter cartridge assembly 40 is located within the first receiving cavity S1.
Referring to fig. 1, the base 20 has a second receiving cavity S2 in which the filter element assembly 40 is placed. When installing filter element group spare 40 in this mounting structure, the business turn over water end embedding second of filter element group spare 40 holds the chamber S2 in, simultaneously, in the inlet tube 21 in the inlet terminal embedding base 20, in the outlet pipe 22 in the outlet terminal embedding base 20. And, the base 20 and the stand 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 tap lever 31 extending out of the base 20. The elastic mechanism 30 has a locked state. With reference to fig. 3 and 4, when the elastic mechanism 30 is in the locked state and the elastic mechanism 30 can fix the filter element assembly 40 in the first receiving cavity S1 and 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, the user can determine whether the elastic mechanism 30 fixes the filter element assembly 40 in the first receiving cavity S1 and the second receiving cavity S2 by determining whether the tap lever 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 state when and only when the tap lever 31 abuts the holder 10, when the filter element assembly 40 is correctly fitted in place. If the tap lever 31 cannot abut against the bracket 10, the elastic mechanism 30 cannot fix the filter element assembly 40 in the first receiving cavity S1 and the second receiving cavity S2, and at this time, the user can reassemble the filter element assembly until the tap lever 31 abuts against the bracket 10.
In one embodiment of assembling the filter cartridge assembly 40 via the mounting structure: by applying an operating force to the poke rod 31, 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 poke rod 31 is released, the filter element assembly 40 is placed in the first accommodating cavity S1 and the second accommodating cavity S2, and at the moment, whether the poke rod 31 abuts against the support 10 or not is judged; if so, the filter element assembly 40 is assembled in place; if not, the filter element assembly 40 is not assembled in place, and the user needs to reassemble the filter element assembly 40 until the tap lever 31 abuts against the support 10.
Note 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 adapted to 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. Holes for passing the outlet terminal and the inlet terminal are formed in the cover plate 60.
It should be noted that, in some embodiments, the filter element assembly 40 can be placed in the first receiving cavity S1 and the second receiving cavity S2 at the same time, and then it is determined whether the tap lever 31 abuts on the base 20; in this configuration, the base 20 is fixedly coupled to the stand 10.
In other embodiments, the base 20 is rotatably coupled to the stand 10. An embodiment of the present application is further illustrated, described, and exemplified in a manner such that the base 20 is pivotally connected to the support frame 10. As shown in fig. 2, the base 20 has a first position state. The housing of the cartridge assembly 40 is generally a cylindrical structure. When the base 20 is in the first position, the first containing cavity S1 and the second containing cavity S2 are coaxial, so that the filter element assembly 40 can be placed in the first containing cavity S1 and the second containing cavity 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 cavity S2, and the filter element assembly 40 is held on the base 20 by the elastic mechanism 30; gradually embedding the filter element assembly 40 into the first accommodating cavity S1 in a rotating manner, and when the first accommodating cavity S1 and the second accommodating cavity S2 are in a coaxial state, the base 20 is in a first position state, as shown in fig. 2, and the filter element assembly 40 is accommodated in the first accommodating cavity S1 and the second accommodating cavity S2 simultaneously; and when the base 20 rotates relative to the support 10 to gradually insert the filter element assembly 40 into the first accommodating cavity S1, the poke rod 31 can rotate relative to the support 10 along with the base 20, and after the filter element assembly 40 is assembled to the first accommodating cavity S1, whether the poke rod 31 abuts against the base 20 is judged. If so, as shown in FIG. 4, the filter element assembly 40 is assembled in place; if not, the filter element assembly 40 is not assembled in place, and the user needs to reassemble the filter element assembly 40 until the tap lever 31 abuts against the support 10.
Further, in the prior art, one end of the frame 10 is typically suspended, so that there is a risk of the cartridge assembly 40 being forced axially out of the base 20 by the water pressure acting on the cartridge assembly 40, and for this purpose, the mounting structure further includes a resilient member 50, as shown in fig. 1. 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 resilient member 50 can abut the filter element assembly 40 when the base 20 is in the first position to provide a first axial force to the filter element assembly 40. The elastic member 50 can resist water pressure based on the deformation thereof, so as to prevent the filter element assembly 40 from causing sealing failure between the filter element assembly 40 and the water pipe of the base 20 due to the influence of the water pressure, and reduce the risk of water leakage. Moreover, the elastic member 50 can provide a first axial force to the filter element assembly 40, and the risk that the filter element assembly 40 is separated due to shaking in the transportation process is effectively reduced.
Also in the present embodiment, when the filter element assembly 40 is mounted to the first receiving cavity S1, the filter element assembly 40 is gradually inserted into the first receiving cavity 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 tap rod 31 cannot abut against the support 10, and the first axial force forms an included angle with the axis of the filter element assembly 40, the filter element assembly 40 is at risk of being ejected, so that whether the filter element assembly 40 is axially installed in place can be judged by observing whether the tap rod 31 abuts against the support 10. Thus, the provision of the resilient member 50 at the end of the frame 10 remote from the base 20 also effectively improves the reliability of the axial positioning of the filter element assembly 40.
In some embodiments, the resilient member 50 is configured as an elastic rib or spring. There is a gap between the end of the filter element assembly 40 and the end of the holder 10. The resilient member 50 extends beyond the end of the frame 10 by a length of 0.1mm to 0.3mm greater than the gap when the resilient member is in the original state, such that the resilient member 50 can abut against the filter element assembly 40 and be compressed and deformed by the assembly force to provide the filter element assembly 40 with a first axial force. The resilient member 50 may be made of plastic or metal sheet.
As an alternative to the above-mentioned embodiment, two opposite side walls of the bracket 10 are respectively configured with a first hooking interface 11 communicating with the first receiving chamber S1 and a second hooking interface 12 communicating with the first receiving chamber S1. Be equipped with the inlet tube 21 and the drain pipe of coaxial setting on the base 20, inlet tube 21 is located in the first interface 11 that articulates, the drain pipe is located in the second articulates interface 12, make the base 20 can be relative support 10 rotates. In operation, the base 20 is rotated. Specifically, the water inlet pipe 21 extends out of the bracket 10 from the first accommodating cavity S1 through the first hanging connector 11, and can be communicated with the incoming water side (water source); the water outlet pipe 22 extends from the second accommodating cavity S2 to the bracket 10 through the second hanging connector 12, and can be communicated with the water using side. The support 10 supports the water inlet pipe 21 through the first hanging connector 11 and supports the water discharge pipe through the second hanging connector 12. As shown in fig. 1, first and second hitch interfaces 11, 12 are each configured as a hook. When the filter element assembly 40 is installed, the filter element assembly 40 is installed in the base 20, the water inlet pipe 21 is installed in the first hooking interface 11, the water outlet pipe 22 is installed in the second hooking interface 12, and then a 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 close to the first accommodating cavity S1 of the bracket 10 until the base 20 is in the first position state.
It should be noted that, in some implementations, 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 using side and the water outlet side of the water purifier need to be released. After the unused filter element assembly 40 or the cleaned filter element assembly 40 is installed in place, the water inlet pipe 21 is fixed and conducted with the water inlet side, the water outlet pipe 22 and the water using side.
As an alternative to the above-mentioned embodiment, a stopper is configured on the support 10. Under the condition that the elastic mechanism 30 is 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 tap lever 31 abuts against the limiting part. The stopper is located at a definite position on the bracket 10. When the filter element assembly is implemented, the exact position of the limiting part is set according to the relative position of the base 20 and the support 10 and the length of the poking rod, so that the filter element assembly 40 can abut against the limiting part after being installed in place. The stopper portion may be constructed in a planar structure as shown in fig. 4. The stop may also be a groove structure or a boss (neither shown) or the like on the bracket 10.
As an alternative to the above 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. When the elastic mechanism 30 is in the locked state, the first section 311 may abut against the bracket 10. The second section 312 is located within the base 20. The second section 312 has a first locking structure 312a configured thereon, the first locking structure 312a mating with a second locking structure 40a on the cartridge assembly 40. As shown in fig. 6, the first locking structure 312a is hook-shaped. The second locking structure 40a of the cartridge assembly 40 is generally protruded and integrally formed on an outer sidewall of the inlet terminal or the outlet terminal. The first locking structure 312a can cooperate with the second locking structure 40a when the elastic mechanism 30 is in the locked state, so as to provide a second axial force for the filter element assembly 40, and the second axial force is used for limiting the water inlet terminal and the water outlet terminal of the filter element assembly 40 to be separated from the corresponding water inlet pipe 21 and the corresponding water outlet pipe 22. Moreover, because the water pressure on the incoming water side has certain fluctuation, the elastic member 50 for providing the first axial force to the filter element assembly 40 is arranged on the support 10, and the elastic member 50 has elasticity and can adaptively change the deformation amount according to the fluctuation of the water pressure, so that the first axial force is variable, the second axial force can change along with the first axial force, severe collision of the first locking structure 312a and the second locking structure 40a during the fluctuation of the water pressure is avoided, 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 the axial movement of the filter element assembly 40, the second axial force between the first locking structure 312a and the second locking structure 40a can be smaller, and the water inlet terminal or the water outlet terminal can be prevented from being pressed for a long time to be deformed or even broken due to failure.
As an alternative to the above-described embodiment, the elastic mechanism 30 has an unlocked state, as shown in fig. 8. In the unlocked state, the user can remove the filter cartridge assembly 40 from the mounting structure or install the filter 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 second section 312 has a circular arc structure in the middle. The second locking structure 40a is disposed on the arc structure. The second section 312 is further provided with a connecting column, which is connected to the arc structure and located at the radial outer side of the arc structure. The connecting column is fixedly connected to the elastic member 32. The elastic member 32 is fixedly coupled to the base 20. The elastic member 32 may be a spring or other member having a deformation capability. In the present embodiment, the elastic member 32 is preferably a spring.
In a specific implementation process, the arc structure is matched with any one of the water inlet terminal or the water outlet terminal so as to 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, so that the tap lever 31 can rotate between the normal position and the triggering position. In general, in order to save labor during unlocking, the end of the second section 312 far from the first section 311 is provided with a first rotation connection 312b. The base 20 is provided with a second rotation connecting portion 23 adapted to the first rotation connecting portion 312b. For example, the first rotation connecting portion 312b is a hole structure (e.g., a through hole), and the second rotation connecting portion 23 is a column structure adapted to the hole structure. For another example, the first rotation connecting portion 312b is a column structure, and the second rotation connecting portion 23 is a hole structure (e.g. a through hole) adapted to the column.
As shown in fig. 4, when the tap lever 31 is in the normal position, the elastic member 32 is in a first elastic state, and the elastic mechanism 30 is in the locked state. The resilient mechanism 30 limits the filter element assembly 40 from large displacements in the axial direction. As shown in fig. 8, when the tap lever 31 is in the triggering position, the elastic member 32 is in the second elastic state, and the elastic mechanism 30 is in the unlocking state, so that the filter cartridge assembly 40 can be taken out of the base 20 or the filter cartridge assembly 40 can be installed in the base 20.
It should be noted that the elastic state of the elastic member 32 can be broadly understood. For example, when the elastic member 32 is in an unstressed state, the elastic state of the elastic member 32 is a state in which the deformation amount is 0. In the present embodiment, the elastic member 32 has a first deformation amount when the elastic member 32 is in the first elastic state. When the elastic element 32 is in the second elastic state, the pulling rod 31 needs to be rotated by applying the force F to the first section 311, and thus the elastic element 32 needs to be deformed in the x direction, so that the first deformation amount of the elastic element 32 in the first elastic state is generally smaller than the second deformation amount of the elastic element 32 in the second elastic state. Typically, the first amount of deformation is 0, i.e., the first locking structure 312a engages the second locking structure 40a when the spring is at its original length. When the tap lever 31 is in the triggering position, the tap lever 31 compresses the spring to deform the spring, and the first locking structure 312a is disengaged from the second locking structure 40a when the tap lever 31 rotates.
As an alternative to the above-described embodiment, the filter cartridge assembly 40 is easily installed and the locking effect of the filter cartridge assembly 40 in use is enhanced. As shown in fig. 7, the base 20 has a second position state, when the base 20 is in the second position state, the axis of the first accommodating cavity S1 and the axis of the second accommodating cavity S2 are arranged at an acute angle, and at this time, the tap lever 31 is detached from the bracket 10. At this time, the elastic member 32 may be compressed by operating the first section 311 such that the first locking structure 312a is disengaged from the second locking structure 40a, thereby unlocking the filter cartridge assembly 40. Specifically, in the embodiment of the present application, as shown in fig. 8, in the case that the first section 311 is driven to move close to the bracket 10 by applying an external force to the first section 311, the tap lever 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 unlocking, the external force applied to the first section 311 needs to have a component directed from the first section 311 to the stent 10 in order to cause the elastic member 32 to compress.
Namely: referring to fig. 4, after the filter cartridge assembly 40 is installed in place, the filter cartridge assembly 40 cannot be unlocked by an external force when the tap lever 31 is in contact with the holder 10. At this time, since the resistance of the elastic member 32 needs to be overcome when unlocking, the elastic member 32 is compressed; the user applies only a force to the tap lever 31 perpendicular to the stand 10 and the direction of the force is directed to the stand 10 by the tap lever 31. However, since the tap lever 31 is in contact with the bracket 10, when the user applies a force in a direction in which the tap lever 31 points to the bracket 10, the tap lever 31 cannot rotate to compress the elastic member 32, and thus cannot be unlocked. Thus, after the filter element assembly 40 is installed in place, the tap lever 31 contacts the bracket 10 and the mounting mechanism is in a self-locking state. The locking of the filter element assembly 40 by the elastic means 30 can be released only when the tap lever 31 is out of contact with the holder 10. Therefore, the mounting structure can effectively keep the filter element assembly 40 fixed after the filter element assembly 40 is mounted in place, improve the reliability of the filter element assembly 40 after replacement, and effectively prevent water leakage in the use process.
Specifically, the second position state of the base 20 may be plural. Generally, the position of the base 20 when the filter element assembly 40 is completely disengaged from the resilient member 50 can be the second position. At this time, since it is not necessary to overcome the first axial force when removing the filter cartridge assembly 40 from the base 20 or installing the filter cartridge assembly 40 into the base 20, it is easy to remove the filter cartridge assembly 40 from the base 20 and also to install the filter cartridge assembly 40 into the base 20.
The embodiment of the present application further provides an installation method of the filter element assembly 40, which includes the following steps:
providing a filter element assembly 40 and a mounting structure for the filter element assembly 40; the mounting structure of the filter element assembly 40 adopts a part or all of the embodiments;
the filter element assembly 40 is placed in the first containing cavity S1 and the second containing cavity S2, and the tap lever 31 is released.
It is judged whether the tap lever 31 abuts against the stand 10,
if yes, the elastic mechanism 30 is in the locked state, and the filter element assembly 40 is installed;
if not, the positions of the filter element assembly 40 in the first accommodating cavity S1 and the second accommodating cavity S2 are adjusted until the tap lever 31 abuts against the support 10, and/or the elastic mechanism 30 is adjusted to make the tap lever 31 abut against the support 10, so that the elastic mechanism 30 is in the locked state.
The installation method of the filter element assembly 40 provided by the embodiment of the application can reduce the water leakage risk and even avoid the water leakage condition caused by the improper assembly of the filter element assembly 40.
The embodiment of the application also provides a water purifier, which comprises the filter element assembly 40 and an installation structure thereof.
