Detailed Implementation

[0033] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0034] According to relevant technologies, the filter cartridge with the filter element is assembled with the filter element seat using a rotary locking structure. That is, after the filter cartridge is installed, it can be rotated at a certain angle and locked and fixed with the filter element seat. The filter cartridge and the filter element seat can be equipped with sensors to detect whether the assembly is in place. However, an additional installation structure is required for the sensors, which makes the installation and assembly of the sensors more complicated.

[0035] Therefore, this utility model provides a filter element installation structure. By setting a first sensing element 30 on the installation structure between the filter element assembly 10 and the filter element seat 20, the first sensing element 30 can sense and cooperate with the second sensing element 40 set in the water purification equipment 100. The first protrusion 121 on the filter cartridge 12 provides an installation position for the first sensing element 30. The structure is simple, the modifications are small, and the installation process of the first sensing element 30 can be simplified.

[0036] like Figures 2 to 5 According to the filter element installation structure of this utility model embodiment, the filter element installation structure includes a filter element assembly 10, a filter element seat 20, a first sensing element 30, and a second sensing element 40.

[0037] The filter element assembly 10 includes a filter cartridge 12, with a plug-in portion at the front end of the filter cartridge 12. A first protrusion 121 is provided on the outer peripheral wall of the plug-in portion, and a first mounting groove 122 is provided on the outer surface of the first protrusion 121. The filter element seat 20 has a plug-in groove 21, and a spiral slide 201 is provided on the inner peripheral wall of the plug-in groove 21. The filter cartridge 12 and the filter element seat 20 are rotatably engaged by the first protrusion 121 and the spiral slide 201. A first sensing element 30 is disposed in the first mounting groove 122, and a second sensing element 40 is fixed relative to the filter element seat 20. The first sensing element 30 includes a trigger portion, and the second sensing element 40 includes a sensing portion. The trigger portion and the sensing portion are inductively coupled. This arrangement simplifies the installation process of the first sensing element 30 and improves the integration of the filter element installation structure.

[0038] Specifically, the filter cartridge assembly 10 is used in the water purification device 100. When the water purification device 100 is running, the filter element 11 in the filter cartridge assembly 10 can be used to filter the water flowing from the water source through the outlet assembly, thereby providing users with clean drinking water. During assembly, the filter cartridge 12 can be inserted into the filter cartridge seat 20 first. The filter cartridge 12 can be rotated relative to the filter cartridge seat 20 so that the first protrusion 121 of the filter cartridge 12 can be rotated to a position that engages with the spiral slide of the filter cartridge seat 20, thereby assembling the filter cartridge 12 and the filter cartridge seat 20.

[0039] More specifically, to simplify the installation structure of the first sensor 30, a first mounting groove 122 can be provided on the outer surface of the first boss 121, and the first sensor 30 can be installed in the first mounting groove 122. This requires minimal modification to the filter cartridge 12 mold, is easy to modify, and is easy to implement. The second sensor 40 can be relatively fixed to the filter element seat 20 (this can be understood as the second sensor 40 being installed on the filter element seat 20, or it can be installed at any position outside the filter element seat 20 and inside the water purification device 100, and its position is relatively fixed to that of the filter element seat 20). In this way, when the filter element assembly 10 and the filter element seat 20 are assembled in place, the second sensor 40 can detect the signal emitted by the first sensor 30, ensuring the accuracy of the assembly and avoiding leakage. Furthermore, the first mounting groove 122 is set on the original first boss 121, eliminating the need for an additional installation structure for the first sensor 30. The structure is simple, requires minimal modification, and simplifies the installation process of the first sensor 30.

[0040] Therefore, according to the filter element installation structure of this utility model embodiment, by setting a first sensing element 30 on the installation structure between the filter element assembly 10 and the filter element seat 20, the first sensing element 30 can sense and cooperate with the second sensing element 40 set in the water purification device 100, and the first protrusion 121 on the filter cartridge 12 provides an installation position for the first sensing element 30. The structure is simple, the modifications are small, and the installation process of the first sensing element 30 can be simplified.

[0041] like Figures 3 to 4 In some embodiments of this utility model, the first mounting groove 122 is formed on the outer surface of the first boss 121 facing away from the filter cartridge 12; this facilitates the installation of the first sensing element 30.

[0042] Understandably, when the water purification equipment 100 is installed, the technician picks up the filter cartridge 12. At this time, the first protrusion 121 of the filter cartridge 12 faces away from the outer surface of the filter cartridge 12 and is opposite to the technician. Therefore, the first mounting groove 122 can be opened on the outer surface of the first protrusion 121 facing away from the filter cartridge 12, so that the technician can install the first sensing element 30 in the first mounting groove 122, thereby improving the convenience of installation.

[0043] Among them, combined with the appendix Figures 3 to 4It is understood that the first boss 121 has a first surface, a second surface and a third surface. The first surface connects the second surface and the outer surface of the filter cartridge 12, the third surface connects the third surface and the outer surface of the filter cartridge 12, and the second surface faces away from the outer surface of the filter cartridge 12. That is, the first mounting groove 122 is formed on the second surface of the first boss 121.

[0044] It should be noted that the radial direction in this embodiment can be understood as the radial direction of the filter element assembly 10, or as the radial direction of the filter cartridge 12.

[0045] like Figures 2 to 4 In some embodiments of this utility model, the first sensing element 30 is set as a first magnetic element, and the second sensing element 40 is set as a Hall switch. The first sensing element 30 and the second sensing element 40 are configured to magnetically engage. In this way, the magnetic engagement of the first magnetic element and the Hall switch ensures that the filter element assembly 10 and the filter element seat 20 are assembled in place.

[0046] For example, the first magnetic component can be disposed in the first mounting groove 122 of the filter cartridge 12, and the Hall switch can be disposed on the filter element holder 20. During the assembly of the water purification equipment 100, the filter cartridge 12 can be inserted into the insertion groove 21 of the filter element holder 20. If the filter cartridge 12 and the filter element holder 20 are properly assembled, the first magnetic component approaches the Hall switch at a predetermined position. The Hall switch senses that the magnetic field reaches the trigger threshold, thereby triggering and sending a signal indicating that the assembly is in place, ensuring that the filter element assembly 10 and the filter element holder 20 are properly assembled. If the filter cartridge 12 and the filter element holder 20 are not properly assembled, the Hall switch senses that the magnetic field has not reached the trigger threshold and therefore does not output a signal indicating that the assembly is in place.

[0047] like Figures 2 to 4 In some embodiments of this utility model, the first sensing element 30 is set as a second magnetic element, and the second sensing element 40 is set as a magnetic reed switch. The first sensing element 30 and the second sensing element 40 are configured to magnetically engage. In this way, the magnetic engagement of the second magnetic element and the magnetic reed switch ensures that the filter element assembly 10 and the filter element seat 20 are assembled in place.

[0048] For example, the second magnetic component can be disposed in the first mounting groove 122 of the filter cartridge 12, and the reed switch can be disposed on the filter element seat 20. During the assembly of the water purification equipment 100, the filter cartridge 12 can be inserted into the insertion groove 21 of the filter element seat 20. If the filter cartridge 12 and the filter element seat 20 are assembled in place, the second magnetic component approaches the reed switch at a predetermined position. The magnetic field strength near the reed switch reaches the threshold for the reed to be attracted, thereby closing the circuit and sending a signal indicating that the assembly is in place, ensuring that the filter element assembly 10 and the filter element seat 20 are assembled in place. If the filter cartridge 12 and the filter element seat 20 are not assembled in place, and the magnetic field strength near the reed switch does not reach the threshold for the reed to be attracted, then no signal indicating that the assembly is in place will be output.

[0049] In some embodiments of this utility model, the first sensing element 30 is a reflective mirror, the second sensing element 40 is a photoelectric sensor, and the spiral slide 201 has a light-transmitting hole opposite to the reflective mirror; in this way, the cooperation of the reflective mirror, the light-transmitting hole and the photoelectric sensor ensures that the filter element assembly 10 and the filter element seat 20 are assembled in place.

[0050] For example, the reflective mirror can be disposed within the first mounting groove 122 of the filter cartridge 12, and the photoelectric sensor can be disposed on the filter element holder 20. During the assembly of the water purification equipment 100, the filter cartridge 12 can be inserted into the insertion groove 21 of the filter element holder 20. If the filter cartridge 12 and the filter element holder 20 are properly assembled, the reflective mirror can receive and reflect light through the light-transmitting hole. The light can be received by the photoelectric sensor, which will then send a signal indicating that the assembly is in place, ensuring that the filter element assembly 10 and the filter element holder 20 are properly assembled. If the filter cartridge 12 and the filter element holder 20 are not properly assembled, the reflective mirror will not be aligned with the light-transmitting hole, the photoelectric sensor will not detect light reflection, and will not output a signal indicating that the assembly is in place.

[0051] In some other embodiments of this utility model, the first sensing element 30 is set as a light-emitting element, the second sensing element 40 is set as a photoelectric sensor, and the spiral slide 201 is provided with a light-transmitting hole opposite to the light-emitting element; in this way, the cooperation of the light-emitting element, the light-transmitting hole and the photoelectric sensor ensures that the filter element assembly 10 and the filter element seat 20 are assembled in place.

[0052] For example, the light-emitting element can be disposed in the first mounting groove 122 of the filter cartridge 12, and the photoelectric sensor can be disposed on the filter element holder 20. During the assembly of the water purification equipment 100, the filter cartridge 12 can be inserted into the insertion groove 21 of the filter element holder 20. If the filter cartridge 12 and the filter element holder 20 are properly assembled, the light-emitting element can emit light through the light-transmitting hole. The light can be received by the photoelectric sensor, which will then issue a signal indicating that the assembly is in place, ensuring that the filter element assembly 10 and the filter element holder 20 are properly assembled. If the filter cartridge 12 and the filter element holder 20 are not properly assembled, the light-emitting element will not be aligned with the light-transmitting hole, the photoelectric sensor will not detect light reflection, and will not output a signal indicating that the assembly is in place.

[0053] In some embodiments of this utility model, the second sensing element 40 is configured as a pressure sensor and is disposed on the inner peripheral wall of the filter element seat 20. The second sensing element 40 is in abutting cooperation with one of the first sensing element 30 and the first boss 121 to detect whether the filter cartridge 12 is installed in the filter element seat 20. In this way, through the structure of the first sensing element 30 and the cooperation of the pressure sensor, it is ensured that the filter element assembly 10 and the filter element seat 20 are assembled in place.

[0054] In some examples, the first sensing element 30 is disposed within the first mounting groove 122, and the pressure sensor can be disposed within the spiral slide 201 of the filter element holder 20. During the assembly of the water purification device 100, if the filter cartridge 12 and the filter element holder 20 are properly assembled, the first sensing element 30 can press against the pressure sensor. The pressure sensor can detect that the pressure has reached a threshold and send a signal indicating that the assembly is complete, ensuring that the filter element assembly 10 and the filter element holder 20 are properly assembled. If the filter cartridge 12 and the filter element holder 20 are not properly assembled, the pressure sensor detects that the pressure of the first sensing element 30 has not reached the threshold and does not output a signal indicating that the assembly is complete.

[0055] In other examples, the outer peripheral surface of the plug is provided with an elastic protrusion, the first sensing element 30 is disposed on the elastic protrusion, and the pressure sensor can be disposed in the spiral slide 201 of the filter element seat 20. When the water purification equipment 100 is assembled, if the filter cartridge 12 and the filter element seat 20 are assembled in place, the first sensing element 30 can press against the pressure sensor under the elastic pressure of the elastic protrusion. The pressure sensor can detect that the pressure has reached the threshold and send a signal that the assembly is in place, ensuring that the filter element assembly 10 and the filter element seat 20 are assembled in place.

[0056] like Figure 5 In some embodiments of this utility model, the inner peripheral wall of the first mounting groove 122 is provided with a plurality of first protrusions 1221, and the first sensing element 30 or the second sensing element 40 is disposed in the first mounting groove 122 and abuts against the first protrusions 1221; this can improve the assembly strength of the first sensing element 30 or the second sensing element 40 and prevent the first sensing element 30 or the second sensing element 40 from coming out.

[0057] Taking the first sensing element 30 as an example: The first sensing element 30 installed in the first mounting groove 122 can abut against a plurality of first protrusions 1221. The plurality of first protrusions 1221 on the inner peripheral wall of the first mounting groove 122 abut against the first sensing element 30 and apply a pre-tightening force, thereby clamping the first sensing element 30 in the first mounting groove 122 and preventing the first sensing element 30 from coming out of the first mounting groove 122.

[0058] In some other embodiments of this utility model, the periphery of the first mounting groove 122 is provided with a plurality of second protrusions, and the first sensing element 30 or the second sensing element 40 is disposed in the first mounting groove 122 and cooperates with the second protrusions to limit the first sensing element 30 or the second sensing element 40 from coming out; in this way, the assembly strength of the first sensing element 30 or the second sensing element 40 can be improved, and the first sensing element 30 or the second sensing element 40 can be prevented from coming out.

[0059] Taking the first sensing element 30 as an example: During installation, the first sensing element 30 can be embedded in the first mounting groove 122. During this process, the first sensing element 30 can abut against a plurality of second protrusions around the periphery of the first mounting groove 122, causing the plurality of second protrusions to deform, thereby passing over the plurality of second protrusions and embedding in the first mounting groove 122. Subsequently, the plurality of second protrusions recover from deformation and abut against the first sensing element 30 in the first mounting groove 122 in the opposite direction, thereby restricting the first sensing element 30 from falling out and improving the installation strength of the first sensing element 30.

[0060] The installation of the second sensing element 40 is the same as described above, and will not be repeated here.

[0061] like Figures 3 to 4 In some embodiments of this utility model, the outer surface of the first boss 121 is also provided with a second mounting groove 123. In the circumferential direction of the filter cartridge 12, the length of the first mounting groove 122 is smaller than the length of the second mounting groove 123. This can improve the assembly applicability and achieve the weight reduction of the filter element assembly 10.

[0062] It is understood that the outer surface of the first boss 121 is provided with a first mounting groove 122 and a second mounting groove 123. In the circumferential direction of the filter cartridge 12, the length of the first mounting groove 122 is smaller than the length of the second mounting groove 123. In this way, the mounting groove of the first boss 121 can be adapted to install the first sensing element 30 and the second sensing element 40 of different sizes; or, when the first sensing element 30 is set as a magnetic element, a reflective mirror, or other structural components of different sizes, the mounting groove can be adapted to assemble its different sizes, thereby improving applicability.

[0063] like Figures 3 to 4 In some embodiments of this utility model, the filter element assembly 10 further includes a housing 11, a filter cartridge 12 disposed inside the housing, and a second sensing element 40 disposed outside the housing. The first sensing element 30 is a magnetic element, and the second sensing element 40 is a Hall sensor. The first sensing element 30 and the second sensing element 40 are magnetically coupled. In this way, the second sensing element 40 can be disposed outside the housing 10, which is convenient for maintenance. There is no need to set up an installation structure for the second sensing element 40 on the filter element seat 20, and the installation detection of the filter cartridge 12 can be ensured.

[0064] Understandably, in order to reduce changes to the structure of the water purification equipment 100, the second sensing element 40 can be placed outside the housing 11 and set as a Hall sensor, while the first sensing element 30 can be set as a magnetic element. When the filter cartridge 12 and the filter element seat 20 are installed in place, the magnetic field of the magnetic element can pass through the housing and be sensed by the Hall sensor set outside the housing 11, thereby detecting whether the filter cartridge 12 is installed in place.

[0065] In some specific examples of this utility model, the filter element assembly 10 is provided with a first locking member, and the filter element seat 20 is provided with a second locking member. When the filter element assembly 10 and the filter element seat 20 are assembled in place, the first locking member and the second locking member lock together, thereby stably locking the filter element assembly 10 on the filter element seat 20, improving the assembly strength and preventing water leakage.

[0066] like Figures 1 to 2 According to the present utility model, the water purification device 100 includes the filter element installation structure in the above embodiment. By applying the filter element installation structure in the above embodiment, water leakage of the water purification device 100 can be avoided, and the working stability of the water purification device 100 can be improved.
