Description

Technical Field

[0001] This invention relates to the technical field of water purification, and more specifically, to a modular water purifier. Background Technology

[0002] As people pursue a higher quality of life, their requirements for water quality are increasing. Water purifiers are becoming increasingly popular because they produce fresher, more hygienic, and safer purified water.

[0003] Some water purifiers require water to be pressurized before they can filter the water, such as reverse osmosis water purifiers. Therefore, these water purifiers are equipped with booster pumps. In the prior art, the booster pump is usually fixed to the housing of the water purifier and connected to the water inlet on the water circuit board inside the water purifier via a hose. The filter cartridge is connected to the water circuit board.

[0004] However, booster pumps installed in this way are difficult to manufacture, install, and repair / replace. During manufacturing and installation, the booster pump and filter cartridge need to be fixed separately inside the water purifier, and hoses need to be connected to the booster pump and the water inlet of the water circuit board. This requires a long installation time and results in high production costs. If the booster pump fails, it needs to be removed from the water purifier, the piping disconnected, and a new booster pump installed following the same manufacturing and installation procedures. This usually requires professional personnel, further increasing the user's operating costs. Summary of the Invention

[0005] To at least partially address the problems existing in the prior art, the present invention provides a modular water purifier. The modular water purifier includes a pump assembly, a pump base assembly, a filter element assembly, and a filter element holder assembly. The modular water purifier also includes a water circuit connection assembly. The pump assembly is detachably installed to the pump base assembly, and the pump assembly and the pump base assembly are in water circuit communication. The filter element assembly is detachably installed to the filter element holder assembly, and the filter element assembly and the filter element holder assembly are in water circuit communication. The pump base assembly and the filter element holder assembly are in water circuit communication via the water circuit connection assembly.

[0006] By configuring the pump assembly, pump base assembly, filter element assembly, and filter element holder assembly as separate modular components, rapid installation and disassembly of the pump assembly and filter element assembly can be achieved. During the production and installation of the modular water purifier, simply fix the pump base assembly and filter element holder assembly separately, connect them via a water circuit connector, and then install the pump assembly and filter element assembly onto their respective components. During maintenance and replacement of the pump and filter element, simply remove them from the pump base assembly and filter element holder assembly, and replace them with new ones. Therefore, the modular water purifier provided by this invention enables rapid installation and disassembly of the pump assembly and filter element assembly, significantly reducing installation and disassembly time and procedures, thereby lowering production and maintenance costs.

[0007] For example, the pump assembly has a pump mounting head, which is provided with a pump inlet connector and a pump outlet connector. The pump mounting head can be used to connect to a pump base assembly. When the pump assembly is installed to the pump base assembly via the pump mounting head, the pump inlet connector and the pump outlet connector can be connected to the water passages within the pump base assembly, thereby further enabling quick assembly and disassembly of the pump assembly and the pump base assembly.

[0008] For example, the pump assembly includes: a housing, with a pump mounting head located on the housing; and a pump, which is encapsulated within the housing. Because different water purifiers have different water circuit layouts and water production capacities, the types and models of pumps used will also differ, resulting in variations in pump shape and structure. Designing a matching pump base assembly for each pump would increase manufacturing costs due to the complex structure of the pump base assembly with various interfaces and internal flow channels. However, by rationally designing the housing structure, various types of pumps can be encapsulated, and the fixing method between the pump and the housing can be more flexible. This makes standardization of the housing and pump base assembly possible, meaning that one or a few pump base assemblies can be adapted to various types of pumps. Therefore, this structure can significantly reduce the number of molds, lower inventory, and reduce production costs.

[0009] For example, the pump inlet connector and pump outlet connector are mounted on the housing, with the pump inlet connected to the pump inlet connector and the pump outlet connected to the pump outlet connector. This allows the same housing and pump base assembly to be used for different water purifiers, thus achieving standardization and greatly facilitating future design and production.

[0010] For example, a first electrical connector is provided on the housing, and the pump's power cord is electrically connected to the first electrical connector. The first electrical connector enables quick connection of the pump assembly to an external power source and facilitates the standardization of the housing.

[0011] For example, the first electrical connector is disposed on the pump mounting head. Thus, by rationally arranging the structure of the pump housing assembly, when the pump assembly is installed onto the pump housing assembly, the first electrical connector can be connected to the power supply through the pump housing assembly; conversely, when disassembling the pump assembly, removing the pump assembly disconnects the first electrical connector from the power supply. This further reduces the time and procedures required for installing and disassembling the pump assembly, thereby lowering installation and disassembly costs.

[0012] Exemplarily, the pump assembly further includes one or more of the following components: an elastic sleeve fitted onto the outer wall of the pump, the elastic sleeve being clamped between the outer wall of the pump and the inner wall of the housing; a first damping elastic member clamped between the pump and the pump mounting head along the axial direction of the housing; and a second damping elastic member clamped between the pump and the inner wall of the tail end of the housing along the axial direction of the housing, the tail end and the pump mounting head being located at opposite ends of the housing along the axial direction. The elastic sleeve can also secure the pump within the housing. By changing the external dimensions of the elastic sleeve, different models of pumps can use the same housing, thereby reducing the number of molds and lowering processing costs. The first and second damping elastic members can form an elastic buffer between the pump and the housing, reducing the impact caused by vibration, thereby reducing pump noise. Furthermore, the first and second damping elastic members can also secure the pump within the housing. Simultaneously, by changing the external dimensions of the first and second damping elastic members, different models of pumps can use the same housing.

[0013] For example, the housing can be a filter bottle. Since the filter bottle and housing have the same structure, they can be manufactured using the same set of molds. This reduces the number of molds, related water connectors, water pipes, and other component types required for producing the filter bottle and housing, lowering inventory and production costs. It also allows the pump and filter element to use the same design and production scheme, reducing design and production complexity and achieving standardization of the booster pump and filter element. The filter bottle can be any existing filter bottle. When using such a filter bottle as the housing, there is no need to design the housing itself, nor to design and produce special molds, related water connectors, water pipes, and other components, significantly reducing costs. Furthermore, the manufacturing process for filter bottles is already very mature, with wider supply channels, a larger market share, and greater versatility and replaceability. More importantly, discarded and expired filter bottles can be selected as the housing, further reducing costs and enabling waste recycling, making it more energy-efficient and environmentally friendly.

[0014] For example, the pump base assembly is provided with a pump base slot, and the pump mounting head of the pump assembly is detachably installed in the pump base slot. The bottom of the pump base slot is provided with a pump base inlet connector and a pump base outlet connector. The pump base inlet connector is connected to the pump inlet connector, and the pump base outlet connector is connected to the pump outlet connector. By connecting the pump base slot to the pump mounting head, the degree of freedom of the pump assembly can be restricted to a certain extent, thereby allowing the pump assembly to be more securely fixed to the pump base assembly. Furthermore, fixing via the pump base slot has advantages such as simple structure and low processing cost.

[0015] For example, the outer wall of the pump base assembly is provided with a pump base connection inlet and a pump base connection outlet. The pump base connection inlet connects to the pump base inlet connector inside the pump base assembly, and the pump base connection outlet connects to the pump base outlet connector inside the pump base assembly. Both the pump base connection inlet and outlet are connected to the water circuit connection assembly. In this way, the water entering and exiting the pump base assembly passes through the filter cartridge assembly, allowing the water purifier's inlet and outlet to be located on the same side as the filter cartridge assembly, resulting in a neater layout of the water purifier's inlet and outlet. Especially when the water purifier is a shell-type water purifier or when other components are located on the outside of the pump base assembly and filter cartridge assembly, having the water purifier's inlet and outlet located on the same side as the filter cartridge assembly makes it easier to arrange the water purifier's outer shell or the other components.

[0016] For example, a second electrical connector is also provided at the bottom of the pump seat slot, which is detachably electrically connected to the first electrical connector. In this way, when installing and removing the pump assembly, the steps of connecting and disconnecting the first electrical connector to the power supply can be reduced, further reducing the time and procedures for installation and removal, thereby reducing the cost of installation and removal.

[0017] For example, the pump base assembly is detachably connected to the filter cartridge assembly. By connecting the pump base assembly to the filter cartridge assembly, only one of the pump base assembly or the filter cartridge assembly needs to be secured, and the other of the pump base assembly or the filter cartridge assembly can be secured accordingly, resulting in lower fixing costs for the modular water purifier. When one of the pump base assembly and the filter cartridge assembly needs to be replaced or repaired, the pump base assembly and the filter cartridge assembly can be disassembled, and only the parts required for repair can be replaced, reducing replacement and repair costs.

[0018] For example, the pump base assembly is hinged to the filter cartridge assembly. By providing a hinge, the modular water purifier can be fixed by securing only one of the pump base assembly or the filter cartridge assembly. Furthermore, in situations where installation space is limited, the pump base assembly and the filter cartridge assembly can rotate relative to each other via the hinge to adapt to the specific requirements.

[0019] For example, the hinge includes: a first hinge shaft connected to the lower side of the pump seat assembly, the first hinge shaft having a first shaft hole; a second hinge shaft connected to the lower side of the filter element seat assembly, the second hinge shaft having a second shaft hole; and a pin passing through the first and second shaft holes, the first hinge shaft being pivotable relative to the second hinge shaft. The hinge connects the lower sides of the pump seat assembly and the filter element seat assembly, reducing interference between them when they pivot relative to each other, making it possible for them to pivot between 0 and 180 degrees. Moreover, this hinge has advantages such as simple structure and flexible pivoting.

[0020] For example, the axis of the first shaft hole is perpendicular to the axial direction of the pump assembly, and the axis of the second shaft hole is perpendicular to the axial direction of the filter element assembly. In this way, the pump assembly and the filter element assembly can pivot in a plane perpendicular to the axes of the first and second shaft holes, respectively, with the axes of the first and second shaft holes as the center. Thus, the structure of the water purifier after pivoting is also regular, and can be adapted to more installation occasions.

[0021] For example, the water connection assembly includes a first water connection pipe and a second water connection pipe located on both sides of the hinge, both of which connect between the pump base assembly and the filter element housing assembly. Positioning the first and second water connection pipes on both sides of the hinge facilitates a pivotal connection between the pump base assembly and the filter element housing assembly, thereby simplifying the structure and making installation easier.

[0022] For example, the pump assembly has a pump mounting head, and the pump seat assembly has a pump seat slot that can accommodate at least a portion of the pump mounting head. A pump locking portion is provided on the outer wall of the pump mounting head, and a pump locking mating portion is provided on the pump seat assembly. The pump locking portion engages with the pump locking mating portion to lock the pump assembly to the pump seat assembly. By providing the pump locking portion and the pump locking mating portion, the pump assembly can be locked to the pump seat assembly, ensuring that the pump assembly will not detach from the pump seat assembly during use, thus improving the stability of the modular water purifier.

[0023] For example, the pump locking part includes a pump locking protrusion disposed on the outer side wall of the pump mounting head. The pump seat assembly includes: a pump seat body, a pump seat slot disposed on the pump seat body; a pump rotating member, which is rotatably disposed on the pump seat body around the pump seat slot between a pump locked position and a pump unlocked position. The pump locking mating part includes a pump locking mating protrusion disposed on the inner side wall of the pump rotating member. The pump locking mating part is spaced apart from the bottom of the slot, and the spaced space is used to accommodate the pump locking part. When the pump rotating member is in the pump unlocked position, the pump locking mating part is offset from the pump locking part along the circumferential direction of the pump seat slot. When the pump rotating member is in the pump locked position, the pump locking mating part is aligned with the pump locking part along the circumferential direction of the pump seat slot, and the pump locking part is engaged in the spaced space. With this arrangement, the pump assembly can be directly inserted into the pump seat body, and the pump assembly can be locked and unlocked by rotating the pump rotating member, ensuring that the pump assembly will not detach from the pump seat body during use, thus improving the stability of the modular water purifier. Furthermore, due to the direct-insertion installation, water will not flow between the pump assembly and the pump base assembly.

[0024] For example, the pump base assembly also includes a pump locking sleeve, which is rotatably fitted onto the pump base body around the pump base slot and connected to the pump rotating component. By providing the pump locking sleeve, dust and other impurities can be effectively prevented from falling onto the pump rotating component, thus avoiding situations such as rotational jamming or unstable rotational speed. Furthermore, it prevents users from contacting the pump rotating component, avoiding dangerous accidents when the pump rotating component is rotating. In addition, the pump locking sleeve also surrounds the pump base body and the pump rotating component, making the pump base assembly look cleaner.

[0025] For example, the pump base assembly also includes a pump reset component connected between the pump base body and the pump rotating component. By providing the pump reset component, the pump rotating component can automatically rotate to the pump locked position when the pump assembly is installed, reducing operation steps and improving the human-machine interaction.

[0026] For example, the filter element assembly has a filter element mounting head, and the filter element seat assembly has a filter element seat slot. The filter element seat slot accommodates at least a portion of the filter element mounting head. A filter element locking part is provided on the outer side wall of the filter element mounting head, and a filter element locking mating part is provided on the filter element seat assembly located on the side of the filter element seat slot. The filter element locking part cooperates with the filter element locking mating part to lock the filter element assembly to the filter element seat assembly. By providing the filter element locking part and the filter element locking mating part, the filter element assembly can be locked to the filter element seat assembly, ensuring that the filter element assembly will not detach from the filter element seat assembly during use, thereby improving the stability of the modular water purifier.

Detailed Implementation

[0041] In the following description, numerous details are provided to enable a thorough understanding of the invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the invention, and that the invention can be practiced without one or more of these details. Furthermore, to avoid obscuring the invention, some technical features well-known in the art have not been described in detail.

[0042] Some water purifiers require pumps, such as the booster pump in reverse osmosis water purifiers and the pump in small-flow water purifiers with storage tanks. To facilitate production, installation, maintenance, and replacement of pumps and filter cartridges, this invention provides a modular water purifier, such as... Figure 1 As shown in the accompanying drawings, some embodiments of the modular water purifier provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0043] like Figure 1-4 As shown, the modular water purifier may include a pump assembly 100, a pump base assembly 200, a filter element assembly 300, a filter element base assembly 400, and a water circuit connection assembly.

[0044] Pump assembly 100 is detachably mounted to pump base assembly 200. The manner in which pump assembly 100 is detachably mounted to pump base assembly 200 can be arbitrary. The manner in which pump assembly 100 is detachably mounted to pump base assembly 200 will be described in detail below with reference to specific embodiments. Pump assembly 100 and pump base assembly 200 can be in water communication. It is understood that pump assembly 100 may include a booster pump and / or a water pump (not shown), etc. Both the booster pump and the water pump can be any type of booster pump and water pump that is currently available or may become available in the future, as long as they can perform their functions. Pump base assembly 200 can be used to fix pump assembly 100. Exemplarily, pump base assembly 200 may be provided with an external interface. The external interface is used to connect external components. External components include, for example, one or more of the following devices: filter cartridge assembly, solenoid valve, high-pressure switch, water quality detector, check valve, etc. External components may also include, for example, one or more external pipes, such as inlet pipes, pure water pipes, and wastewater pipes, which are connected to external interfaces.

[0045] The filter element assembly 300 is detachably mounted to the filter element holder assembly 400. The manner in which the filter element assembly 300 is detachably mounted to the filter element holder assembly 400 can be arbitrary. The manner in which the filter element assembly 300 is detachably mounted to the filter element holder assembly 400 will be described in detail below with reference to specific embodiments. The filter element assembly 300 can employ various types of filter elements known in the art or that may emerge in the future. For ease of description, the principle of the present invention will be illustrated below using the filter element assembly 300 including a reverse osmosis filter element as an example. It should be noted that the filter element assembly 300 may only contain a reverse osmosis filter element; alternatively, the filter element assembly 300 may also be a composite filter element composed of a reverse osmosis filter element and other filter media. Of course, the filter element assembly 300 and the filter element holder assembly 400 can be in water communication. The filter element holder assembly 400 can be used to fix the filter element assembly 300. The filter element holder assembly 400 may also be provided with one or more of the aforementioned external interfaces. Those skilled in the art can select the type and number of external interfaces provided on the pump seat assembly 200 and the filter seat assembly 400 as needed.

[0046] The pump base assembly 200 and the filter element housing assembly 400 can be connected by a water passage connection assembly. The water passage connection assembly can include any structure that enables water passage connection, such as a flexible hose, a rigid pipe, or internal water passages within the pump base assembly 200 and the filter element housing assembly 400. The water passage connection assembly can include, for example, a first water passage connection pipe 510 (e.g.,...). Figure 3 (as shown) and the second water circuit connection pipe 520 (as shown) Figure 1-2 and Figure 4 (As shown).

[0047] After the pump base assembly 200 and the filter cartridge assembly 400 are connected by the water circuit connection component, they can form a complete water circuit within the modular water purifier. (See [link]) Figure 9 When the booster pump included in the pump assembly 100 is powered on and started, water can enter the filter assembly through the water circuit connection assembly under the action of the booster pump. In this way, the modular water purifier can provide high-pressure water to its downstream reverse osmosis filter.

[0048] Preferably, the pump base assembly 200 and the filter cartridge base assembly 400 can be fixed at any suitable location. Installing the pump assembly 100 and the filter cartridge assembly 300 onto the pump base assembly 200 and the filter cartridge base assembly 400 respectively allows for separate fixation of the pump and the filter cartridge. For water purifiers with a casing, the pump base assembly 200 and the filter cartridge base assembly 400 can be fixed at any suitable location within the water purifier. For water purifiers without a casing, the pump base assembly 200 and the filter cartridge base assembly 400 can be installed independently.

[0049] By configuring the pump assembly 100, pump base assembly 200, filter element assembly 300, and filter element base assembly 400 as individual modular components, the pump assembly 100 and filter element assembly 300 can be quickly installed and removed. During the production and installation of the modular water purifier, simply fix the pump base assembly 200 and filter element base assembly 400 in place, connect them via a water circuit connector, and then install the pump assembly 100 and filter element assembly 300 onto the respective components. During maintenance and replacement of the pump and filter element, simply remove the pump assembly 100 and filter element assembly 300 from the pump base assembly 200 and filter element base assembly 400, respectively, and replace them with new ones.

[0050] Therefore, the modular water purifier provided by the present invention can realize the rapid installation and disassembly of the pump assembly 100 and the filter assembly 300, greatly reducing the installation and disassembly time and procedures, thereby reducing production and maintenance costs.

[0051] Preferably, such as Figure 3-4 As shown, the pump assembly 100 may have a pump mounting head. The pump mounting head of the pump assembly 100 refers to the portion of the pump assembly 100 that connects to the pump base assembly 200. In the figure, it is shown as the lower end of the pump assembly 100. The pump mounting head may be equipped with a pump inlet connector (not shown due to angle) and a pump outlet connector (not shown due to angle). The pump mounting head can be used to connect to the pump base assembly 200. When the pump assembly 100 is installed onto the pump base assembly 200 via the pump mounting head, the pump inlet connector and the pump outlet connector can connect to the water passages within the pump base assembly 200, thereby further enabling quick assembly and disassembly of the pump assembly 100 and the pump base assembly 200.

[0052] A pump seat slot 210 may be provided on the pump seat assembly 200. The pump mounting head of the pump assembly 100 is detachably installed in the pump seat slot 210. A pump seat inlet connector 221 and a pump seat outlet connector 222 may be provided at the bottom of the pump seat slot 210. The pump seat inlet connector 221 is connected to the pump inlet connector of the pump assembly 100. The pump seat outlet connector 222 is connected to the pump outlet connector of the pump assembly 100.

[0053] By connecting the pump seat slot 210 to the pump mounting head, the degree of freedom of the pump assembly 100 can be restricted to a certain extent, thereby allowing the pump assembly 100 to be more securely fixed to the pump seat assembly 200. Furthermore, fixing via the pump seat slot 210 has advantages such as simple structure and low processing cost.

[0054] The outer wall of the pump base assembly 200 may be provided with a pump base connection inlet 231 and a pump base connection outlet 232. The pump base connection inlet 231 is internally connected to the pump base inlet connector 221 within the pump base assembly 200. The pump base connection outlet 232 is internally connected to the pump base outlet connector 222 within the pump base assembly 200. Both the pump base connection inlet 231 and the pump base connection outlet 232 are connected to the water circuit connection assembly.

[0055] In this way, the water inlet and outlet of the pump base assembly 200 both pass through the filter cartridge assembly 400, allowing the water purifier's inlet and outlet to be located on the same side as the filter cartridge assembly 400, resulting in a neater layout. This is especially beneficial when the water purifier has a casing or when other components are located outside the pump base assembly 200 and filter cartridge assembly 400; having the inlet and outlet on the same side as the filter cartridge assembly 400 makes it easier to arrange the water purifier's casing or other components.

[0056] Preferably, such as Figure 1-4 As shown, the pump assembly 100 may include a housing 120 and a pump 130. A pump mounting head may be located on the housing 120. The housing 120 is secured to the pump base assembly 200 via the mounting head. The pump 130 is encapsulated within the housing 120. The housing 120 may be bottle-shaped as shown; in other embodiments not shown, the housing 120 may also have other shapes, as long as they can accommodate the pump 130.

[0057] Because different water purifiers have different water circuit layouts and water production capacities, the types and models of pumps 130 used will also differ, resulting in variations in the shape and structure of the pumps 130. Designing a matching pump base assembly 200 for each pump 130 would increase manufacturing costs due to the complex structure of the pump base assembly 200 with its various interfaces and internal flow channels. However, by rationally designing the structure of the housing 120, various types of pumps 130 can be encapsulated, and the fixing method between the pump 130 and the housing 120 can be more flexible, for example, through accessory components (such as elastic sleeves). This makes standardization of the housing 120 and the pump base assembly 200 possible, meaning that one or a few pump base assemblies 200 can be adapted to various types of pumps 130. Therefore, this structure can significantly reduce the number of molds, lower inventory, and reduce production costs.

[0058] Optionally, the pump inlet and outlet of the pump 130 can be directly connected to the pump base assembly 200. A through-hole can be provided on the housing 120, through which the pump inlet and outlet of the pump 130 connect to the pump base inlet connector 221 and pump base outlet connector 222 on the pump base assembly 200. In this case, the pump inlet and outlet through the through-hole form the aforementioned pump inlet connector and pump outlet connector.

[0059] For example, the aforementioned pump inlet and outlet connectors can be mounted on the housing 120. The pump inlet of the pump 130 itself can be connected to the pump inlet connector, and the pump outlet of the pump 130 itself can be connected to the pump outlet connector. Optionally, the pump inlet of the pump 130 itself and the pump inlet connector on the housing 120 can be connected via a quick connector. A quick connector is a connector that allows for connection or disconnection of pipelines without tools. By providing a quick connector, it is easy to disassemble the pump 130 from the housing 120. Optionally, the pump inlet of the pump 130 itself and the pump inlet connector on the housing 120 can also be connected by welding, bonding, or any other method. The pump outlet of the pump 130 itself and the pump outlet connector on the housing 120 can also be connected using any of the above methods. The connection methods between the pump inlet and outlet of the pump 130 itself and the pump inlet and outlet connectors on the housing 120 can be the same or different.

[0060] Since the interface positions and dimensions of different pump models 130 may vary, the housing 120 serves as an adapter between the pump 130 and the pump base assembly 200, enabling complete standardization of both. If needed, the internal fixing of different pumps 130 to the housing 120 can be achieved using additional components such as elastic sleeves, and water circuit connections can be made using additional components such as hoses. This allows the same housing 120 and pump base assembly 200 to be used for different water purifiers, achieving standardization and greatly facilitating future design and production.

[0061] like Figure 8 As shown, the filter cartridge assembly 300 may include a filter bottle 320 and a filter element 330 housed within the filter bottle 320. The housing 120 may be a filter bottle 320. Optionally, the housing 120 may also be any existing suitable filter bottle, such as a filter bottle for a pre-filter cartridge assembly, a filter bottle for a post-filter cartridge assembly, etc., in which the inlet and outlet ports of the filter bottle can serve as the inlet and outlet ports of the housing 120; the filter bottle 320 may also include a filter bottle for a reverse osmosis filter cartridge assembly or other filter bottles with more than two ports, two of which can serve as the inlet ports of the housing 120, and the remaining ports may be used to install the first electrical connector 110 or left unused. Correspondingly, the pump base assembly 200 may also be a filter cartridge base assembly 400.

[0062] Since the filter bottle 320 and the housing 120 have the same structure, they can be manufactured using the same set of molds. This reduces the number of molds, related water connectors, water pipes, and other components required for producing the filter bottle 320 and housing 120, thus reducing inventory and production costs. Furthermore, it allows the pump and filter element to use the same design and production scheme, reducing design and production complexity and achieving standardization of the booster pump and filter element. The filter bottle 320 can be any existing filter bottle. When using such a filter bottle as the housing 120, there is no need to design the housing 120 itself, eliminating the need for dedicated molds and further reducing the number of related water connectors, water pipes, and other components, significantly lowering costs. Simultaneously, the manufacturing process for the filter bottle 320 is already very mature, with wider supply channels, a larger market presence, and greater versatility and replaceability. More importantly, discarded and expired filter bottles 320 can be selected as the housing 120, further reducing costs and enabling waste recycling, making it more energy-efficient and environmentally friendly.

[0063] Preferably, a first electrical connector 110 may also be provided on the housing 120. The power cord of the pump 130 is electrically connected to the first electrical connector 110. By supplying power to the first electrical connector 110, the motor inside the pump 130 can be started, thereby starting the pump. The power cord of the pump 130 and the first electrical connector 110 can be electrically connected in any way, such as using a quick-connect fitting. The first electrical connector 110 can be a plug or a socket. The first electrical connector 110 enables quick connection between the pump assembly 100 and an external power source and facilitates the standardization of the housing 120.

[0064] Furthermore, such as Figure 4 As shown, the first electrical connector 110 can be disposed on the pump mounting head. A second electrical connector 240 can also be disposed at the bottom of the pump seat slot 210. The second electrical connector 240 can be detachably electrically connected to the first electrical connector 110. The second electrical connector 240 and the first electrical connector 110 can adopt structures known in the art, such as plugs and sockets, and electrical contacts, and therefore will not be described in further detail herein. By reasonably arranging the structure of the pump seat assembly 200, when the pump assembly 100 is installed onto the pump seat assembly 200, the first electrical connector 110 can be connected to the power supply through the pump seat assembly 200; conversely, when the pump assembly 100 is disassembled, removing the pump assembly 100 disconnects the first electrical connector 110 from the power supply. This further reduces the time and procedures required for installing and disassembling the pump assembly 100, thereby reducing installation and disassembly costs.

[0065] Preferably, such as Figure 8As shown, the pump assembly 100 may further include one or more of an elastic sleeve 140, a first damping elastic element 151, and a second damping elastic element 152. The elastic sleeve 140 may be fitted onto the outer wall of the pump 130. The elastic sleeve 140 may be clamped between the outer wall of the pump 130 and the inner wall of the housing 120. The first damping elastic element 151 may be clamped between the pump 130 and the pump mounting head along the axial direction of the housing 120. The second damping elastic element 152 may be clamped between the pump 130 and the inner wall of the tail portion of the housing 120 along the axial direction of the housing 120. The tail portion and the pump mounting head may be respectively located at two ends of the housing 120 along the axial direction.

[0066] The elastic sleeve 140 can also fix the pump 130 inside the housing 120. By changing the external dimensions of the elastic sleeve 140, different models of pumps 130 can use the same housing 120, thereby reducing the number of molds and reducing processing costs.

[0067] The first damping elastic element 151 and the second damping elastic element 152 can have the same or different structures. Preferably, the first damping elastic element 151 and the second damping elastic element 152 can be springs. As is known in the art, the pump 130 vibrates during operation, and generates significant noise when it impacts the housing 120. The first damping elastic element 151 and the second damping elastic element 152 can form an elastic buffer between the pump 130 and the housing 120, reducing the impact caused by vibration and thus reducing the noise of the pump 130. Furthermore, the first damping elastic element 151 and the second damping elastic element 152 can also fix the pump 130 within the housing 120. Simultaneously, by changing the external dimensions of the first damping elastic element 151 and the second damping elastic element 152, different models of pumps 130 can use the same housing 120.

[0068] Preferably, the pump base assembly 200 is detachably connected to the filter element housing assembly 400. The method by which the pump base assembly 200 is detachably connected to the filter element housing assembly 400 can be arbitrary, such as through threaded connections, snap-fit, etc. Based on this, the water connection assembly includes a first water inlet and a second water inlet. The first water inlet can be located on the pump base assembly 200. The second water inlet can be located on the filter element housing assembly 400. A snap-fit ​​connector and a snap-fit ​​seat are respectively provided on the first water inlet and the second water inlet. The first water inlet and the second water inlet are connected by snapping the snap-fit ​​connector into the snap-fit ​​seat.

[0069] By connecting the pump base assembly 200 to the filter cartridge assembly 400, only one of the pump base assembly 200 or the filter cartridge assembly 400 needs to be fixed, and the other of the pump base assembly 200 or the filter cartridge assembly 400 can be fixed accordingly, resulting in lower fixing costs for the modular water purifier. When one of the pump base assembly 200 and the filter cartridge assembly 400 needs to be replaced or repaired, the pump base assembly 200 and the filter cartridge assembly 400 can be disassembled, and only the parts required for repair can be replaced, reducing the cost of replacement and repair.

[0070] Preferably, the pump base assembly 200 can be hinged to the filter cartridge assembly 400 via a hinge 250. The hinge 250 can be any type of existing or future hinge, as long as it achieves the aforementioned functions. By providing the hinge 250, the modular water purifier can be fixed by securing only one of the pump base assembly 200 or the filter cartridge assembly 400. Furthermore, in situations with limited installation space, the pump base assembly 200 and the filter cartridge assembly 400 can rotate relative to each other via the hinge 250 to adapt to the specific requirements.

[0071] Furthermore, such as Figure 1-4 As shown, hinge 250 may include a first hinge shaft 251, a second hinge shaft 252, and a pin 253. The first hinge shaft 251 may be connected to the lower part of the side surface of the pump seat assembly 200. The first hinge shaft 251 may have a first shaft hole. The second hinge shaft 252 may be connected to the lower part of the side surface of the filter element seat assembly 400. The second hinge shaft 252 may have a second shaft hole. The pin 253 may pass through the first shaft hole and the second shaft hole. The first hinge shaft 251 is pivotable relative to the second hinge shaft 252. Hinges 250 connect the lower parts of the sides of the pump seat assembly 200 and the filter element seat assembly 400, reducing interference between them when they pivot relative to each other, making it possible for them to pivot between 0 and 180 degrees. Moreover, this hinge 250 has advantages such as simple structure and flexible pivoting.

[0072] Furthermore, such as Figure 1-4 As shown, the axis of the first shaft hole can be perpendicular to the axial direction of the pump assembly 100. The axis of the second shaft hole can be perpendicular to the axial direction of the filter element assembly 300. In this way, the pump assembly 100 and the filter element assembly 300 can pivot in a plane perpendicular to the axes of the first and second shaft holes, respectively, with the axes of the first and second shaft holes as their centers. This results in a regular structure for the water purifier after pivoting, making it adaptable to more installation scenarios.

[0073] Preferably, combined with Figure 1-4As shown, the water connection assembly may include a first water connection pipe 510 and a second water connection pipe 520. The first water connection pipe 510 and the second water connection pipe 520 may be located on opposite sides of the hinge 250. Both the first water connection pipe 510 and the second water connection pipe 520 are connected between the pump base assembly 200 and the filter element base assembly 400. Specifically, the pump base assembly 200 may be provided with a pump base connection inlet 231 and a pump base connection outlet 232. The pump base connection inlet 231 and the pump base connection outlet 232 may be located on opposite sides of the hinge 250. The filter element base assembly 400 may be provided with a filter element base connection inlet 432 and a filter element base connection outlet 431. The filter element base connection inlet 432 and the filter element base connection outlet 431 may be located on opposite sides of the hinge 250. The pump base connection inlet 231 and the filter element seat connection outlet 431 can be located on one side of the hinge 250. The pump base connection outlet 232 and the filter element seat connection inlet 432 can be located on the other side of the hinge 250. The first water connection pipe 510 can connect the pump base connection inlet 231 and the filter element seat connection outlet 431. The second water connection pipe 520 can connect the pump base connection outlet 232 and the filter element seat connection inlet 432. The first water connection pipe 510 and the second water connection pipe 520 can be flexible hoses, which can avoid being restricted by the water connection components when the pump base assembly 200 moves relative to the filter element seat assembly 400. The first water connection pipe 510 and the second water connection pipe 520 can be used for the inlet and outlet pipes of the pump 130, respectively. By placing the first water circuit connecting pipe 510 and the second water circuit connecting pipe 520 on both sides of the hinge 250, it is more convenient to set the pump seat assembly 200 and the filter element seat assembly 400 as pivotable connections. As a result, the structure of the water circuit connecting assembly is simple and the installation is convenient.

[0074] Preferably, such as Figure 4-5 As shown, pump assembly 100 may have a pump mounting head. Pump base assembly 200 may have a pump base slot 210. Pump base slot 210 may accommodate at least a portion of the pump mounting head. A pump locking part may be provided on the side wall of the pump mounting head. A pump locking engagement part located on the outer side of the pump base slot 210 may be provided on pump base assembly 200. The pump locking part and the pump locking engagement part can cooperate to lock pump assembly 100 to pump base assembly 200. The pump locking part and the pump locking engagement part may have various structures, as long as they can lock and unlock. Several preferred embodiments will be described in detail below. By providing the pump locking part and the pump locking engagement part, pump assembly 100 can be locked to pump base assembly 200, ensuring that pump assembly 100 will not detach from pump base assembly 200 during use, thereby improving the stability of the modular water purifier.

[0075] In a preferred embodiment, such as Figure 4As shown, the pump locking part 160 can be a pump locking protrusion provided on the outer side wall of the pump mounting head. The pump locking protrusion can be provided at any suitable position on the outer side wall of the mounting head. The number of pump locking protrusions on the outer side wall of the pump mounting head can be arbitrary. Preferably, there are multiple pump locking protrusions, and they are evenly distributed along the circumferential direction of the outer side wall of the pump mounting head.

[0076] The pump base assembly may include a pump base body 281 and a pump rotating member 282. A pump base slot 210 may be disposed on the pump base body 281. The pump rotating member 282 may be rotatably disposed on the pump base body 281 around the pump base slot 210, between a pump locked position and a pump unlocked position. The pump rotating member 282 may be rotated manually between the pump locked position and the pump unlocked position. Optionally, the pump rotating member 282 may also be driven to rotate by a component such as a motor, between the pump locked position and the pump unlocked position. The pump locking engagement portion 270 may be a pump locking engagement protrusion disposed on the inner sidewall of the pump rotating member 282. The pump locking engagement portion 270 is spaced apart from the bottom of the pump base slot 210. The spaced space may be used to accommodate the pump locking portion 160. When the pump rotating member 282 is in the pump unlocked position, the pump locking engagement portion 270 may be offset from the pump locking portion 160 in the circumferential direction of the pump base slot 210. In this way, the pump assembly 100 can be inserted into or removed from the pump seat 281 along its axial direction. When the pump rotating member 282 is in the pump locked position, the pump locking engagement part 270 can be aligned with the pump locking part 160 along the circumferential direction of the pump seat slot 210, and the pump locking part 160 can be engaged in the spaced-apart space. At this time, the pump locking engagement part 270 can be fully aligned with the pump locking part 160, or it can be partially aligned with the pump locking part 160, as long as the pump locking part 160 can be engaged in the spaced-apart space. In this way, the pump assembly 100 cannot be pulled out, thereby locking the pump assembly 100 to the pump seat 281.

[0077] With this configuration, the pump assembly 100 can be directly inserted into the pump base 281. The pump assembly 100 is locked and unlocked by rotating the pump rotating component 282, ensuring that the pump assembly 100 will not detach from the pump base 281 during use, thus improving the stability of the modular water purifier. Furthermore, due to the direct insertion installation, water flow between the pump assembly 100 and the pump base assembly 200 will not be interrupted.

[0078] Preferably, such as Figure 3-4As shown, the pump seat assembly 200 may further include a pump locking sleeve 290. The pump locking sleeve 290 is rotatably fitted onto the pump seat body 281 around the pump seat slot 210. The pump locking sleeve 290 can be connected to the pump rotating member 282. The manner in which the pump locking sleeve 290 is connected to the pump rotating member 282 can be arbitrary. In the embodiment shown, the inner sidewall of the pump locking sleeve 290 may be provided with a protrusion 291. The outer sidewall of the pump rotating member 282 may be provided with a groove 292. The pump locking sleeve 290 is connected to the pump rotating member 282 by engaging the protrusion 291 into the groove 292. In other embodiments not shown, the pump locking sleeve 290 can be connected to the pump rotating member 282 by welding, bonding, or other methods.

[0079] By installing the pump locking sleeve 290, dust and other impurities can be effectively prevented from falling onto the pump rotating component 282, which could lead to rotational jamming or unstable rotation speed. Furthermore, it prevents users from contacting the pump rotating component 282, avoiding potential accidents during its rotation. In addition, the pump locking sleeve 290 also surrounds the pump base 281 and the pump rotating component 282, making the pump base assembly 200 appear cleaner.

[0080] Preferably, such as Figure 3-4 As shown, the pump base assembly 200 may further include a pump reset member 283. The pump reset member 283 may be connected between the pump base body 281 and the pump rotating member 282. The pump reset member 283 can be used to return the pump rotating member 282 from the pump unlocked position to the pump locked position. Preferably, the pump reset member 283 may be a spring.

[0081] As described above, during the installation of pump assembly 100, the pump rotating member 282 moves to the pump unlock position, at which point the pump reset member 283 can be in a state of significant compression or stretching. When pump assembly 100 is installed in place, i.e., when the pump locking part 160 passes over the pump locking mating part 270 and moves to the bottom between the pump locking mating part 270 and the pump seat slot 210, the pump reset member 283 can release its stored elastic potential energy, causing the pump rotating member 282 to return to the pump locked position. At this time, the pump reset member 283 can be in a naturally extended state, or in a state of minor compression or stretching.

[0082] By setting the pump reset component 283, when the pump assembly 100 is installed in place, the pump rotating component 282 can rotate to the pump locking position by itself, reducing operation steps and improving the human-machine interaction.

[0083] Furthermore, such as Figure 4As shown, both the pump locking part 160 and the pump locking mating part 270 can be wedge-shaped protrusions. When the pump assembly 100 is not yet inserted into the pump seat slot 210 on the pump seat assembly 200, the pump rotating member 282 is in the pump locked position. As the pump assembly 100 is gradually inserted into the pump seat slot 210 along the axial direction, the pump locking part 160 can squeeze the pump locking mating part 270, thereby driving the pump rotating member 282 to rotate from the pump locked position to the pump unlocked position. When the pump rotating member 282 is in the pump unlocked position, the pump locking part 160 on the pump assembly 100 can pass over the pump locking mating part 270 and move into the space spaced between the pump locking mating part 270 and the bottom of the pump seat slot 210. At this time, the pump rotating member 282 can be manually rotated or returned to the pump locked position by the pump reset member 283, thereby locking the pump assembly 100 onto the pump seat body 281.

[0084] With this configuration, when the pump assembly 100 is inserted into the pump seat slot 210, the pump rotating component 282 can rotate accordingly. This reduces the number of operation steps while locking the pump assembly 100 to the pump seat 281, resulting in a better human-machine interaction.

[0085] In the second preferred embodiment, such as Figure 5 As shown, the pump locking portion 160' may include a locking groove on the outer side wall of the mounting head of the pump assembly 100. The locking groove may extend in the circumferential direction of the pump mounting head. One end of the locking groove is closed and the other end is open. The locking groove may be formed by an L-shaped protrusion 293 provided on the pump mounting head. The pump locking engagement portion 270' may be a locking protrusion provided on the inner side wall of the pump seat slot 210. The locking protrusion can engage with the locking groove. Exemplarily, two locking protrusions may be provided on the inner side wall of the pump seat slot 210.

[0086] When installing the pump assembly 100, the L-shaped protrusion 293 on the pump assembly 100 can be aligned with the gap between the two locking protrusions. After the pump assembly 100 is inserted into place axially, the pump assembly 100 can be rotated to allow the locking protrusion to enter the locking groove from the opening of the locking groove, thus locking the locking protrusion into the locking groove and securing the pump assembly 100 to the pump seat assembly 200. When disassembling the pump assembly 100, rotating the pump assembly 100 can separate the locking protrusion from the locking groove, thus unlocking the pump assembly 100 from the pump seat assembly 200. Then, the pump assembly 100 can be pulled out axially.

[0087] By setting the locking protrusion and locking groove, the pump assembly 100 can be easily and quickly locked to the pump base assembly 200, ensuring that the pump assembly 100 will not detach from the pump base body 281 during use, thus improving the stability of the modular water purifier. Furthermore, the locking protrusion and locking groove have a simple structure and are easy to implement.

[0088] In the third preferred embodiment, such as Figure 6 As shown, both the pump inlet and outlet connectors are rigid water pipes extending axially along the housing 120. The rigid water pipes can extend from the mounting head in a direction away from the housing 120. Correspondingly, the pump seat inlet connector 221 and pump seat outlet connector 222 can also be rigid water pipes. The pump seat assembly 200 may further include a first quick connector 295 and a second quick connector 296. With the pump assembly 100 installed on the pump seat assembly 200, the first quick connector 295 can be fitted onto the pump inlet connector and the pump seat inlet connector 221, allowing them to connect. The second quick connector 296 can be fitted onto the pump outlet connector and the pump seat outlet connector 222, allowing them to connect.

[0089] This design allows the pump assembly 100 to be locked to the pump base assembly 200, ensuring that the pump assembly 100 will not detach from the pump base assembly 200 during use, thus improving the stability of the modular water purifier. Furthermore, this solution has advantages such as simple structure and ease of implementation.

[0090] In the fourth preferred embodiment, such as Figure 7 As shown, the pump locking portion 160” of the pump assembly 100 may include an external thread on its mounting head, and the pump locking mating portion 270” of the pump seat assembly 200 may also include an external thread on its outer peripheral surface. The pump assembly 100 and the pump seat assembly 200 can be connected by a threaded sleeve 904, which may have an internal thread. The pump assembly 100 and the pump seat assembly 200 are locked by being threadedly connected to the threaded sleeve 900.

[0091] The above only describes the differences between the second to fourth embodiments and the first embodiment. The same reference numerals are used for the same or similar components as in the second to fourth embodiments and the first embodiment. For the sake of brevity, these same or similar components will not be described in detail here.

[0092] Preferably, such as Figure 3-4As shown, the filter element assembly 300 may have a filter element mounting head. The mounting head of the filter element assembly 300 refers to the portion of the filter element assembly 300 that connects to the filter element seat assembly 400, and is shown as the lower end of the filter element assembly 300 in the figure. The filter element seat assembly 400 may have a filter element seat slot 410. The filter element seat slot 410 can accommodate at least a portion of the filter element mounting head. A filter element locking part may be provided on the side wall of the filter element mounting head. A filter element locking engagement part located on the side of the filter element seat slot 410 may be provided on the filter element seat assembly 400. The filter element locking part and the filter element locking engagement part can cooperate to lock the filter element assembly 300 to the filter element seat assembly 400. The filter element locking part and the filter element locking engagement part can have various structures, as long as they can lock and unlock each other. By setting up a filter element locking part and a filter element locking mating part, the filter element assembly 300 can be locked to the filter element seat assembly 400, ensuring that the filter element assembly 300 will not detach from the filter element seat assembly 400 during use, thereby improving the stability of the modular water purifier.

[0093] In a preferred embodiment, such as Figure 4 As shown, the filter element locking part 360 can be a filter element locking protrusion provided on the outer wall of the filter element mounting head. The filter element locking protrusion can be provided at any suitable position on the outer wall of the filter element mounting head. The number of filter element locking protrusions on the outer wall of the filter element mounting head can be arbitrary. Preferably, there are multiple filter element locking protrusions, and they are evenly distributed along the circumferential direction of the outer wall of the filter element mounting head.

[0094] The filter cartridge holder assembly includes a filter cartridge holder body 481 and a filter cartridge rotating member 482. A filter cartridge holder slot 410 can be disposed on the filter cartridge holder body 481. The filter cartridge rotating member 482 is rotatably disposed on the filter cartridge holder body 481 around the filter cartridge holder slot 410, between a filter cartridge locked position and a filter cartridge unlocked position. The filter cartridge rotating member 482 can be rotated manually between the filter cartridge locked position and the filter cartridge unlocked position. Optionally, the filter cartridge rotating member 482 can also be driven to rotate by a motor or other components, between the filter cartridge locked position and the filter cartridge unlocked position. The filter cartridge locking engagement part 470 can be a filter cartridge locking engagement protrusion disposed on the inner side wall of the filter cartridge rotating member 482. The filter cartridge locking engagement part 470 is spaced apart from the bottom of the filter cartridge holder slot 410. The spaced space can be used to accommodate the filter cartridge locking part 360. When the filter element rotating member 482 is in the filter element unlocked position, the filter element locking engagement part 470 can be offset from the filter element locking part 360 along the circumferential direction of the filter element seat slot 410. In this way, the filter element assembly 300 can be inserted into or removed from the filter element seat 481 along its axial direction. When the filter element rotating member 482 is in the filter element locked position, the filter element locking engagement part 470 can be aligned with the filter element locking part 360 along the circumferential direction of the filter element seat slot 410, and the filter element locking part 360 can be engaged within the spaced-apart space. At this time, the filter element locking engagement part 470 can be completely aligned with the filter element locking part 360, or partially aligned with the filter element locking part 360, as long as the filter element locking part 360 can be engaged within the spaced-apart space. This prevents the filter element assembly 300 from being pulled out, thereby locking the filter element assembly 300 to the filter element seat 481.

[0095] With this design, the filter element assembly 300 can be directly inserted into the filter element holder 481. The filter element assembly 300 is locked and unlocked by rotating the filter element rotating component 482, ensuring that it will not detach from the filter element holder 481 during use, thus improving the stability of the modular water purifier. Furthermore, due to the direct insertion installation, water will not flow between the filter element assembly 300 and the filter element holder assembly 400.

[0096] Preferably, such as Figure 3-4As shown, the filter element holder assembly 400 may further include a filter element locking sleeve 490. The filter element locking sleeve 490 is movably fitted onto the filter element holder body 481 along the axial direction of the filter element holder slot 410. A first inclined surface 491 is provided on the side wall of the filter element locking sleeve 490. The first inclined surface 491 may be formed by a recess provided on the side wall of the filter element locking sleeve 490. A second inclined surface 492 may be provided on the side wall of the filter element rotating member 482. The second inclined surface 492 may be formed by a protrusion provided on the outer side wall of the filter element rotating member 482. The first inclined surface 491 faces the second inclined surface 492. The first inclined surface 491 and the second inclined surface 492 are parallel to each other. Both the first inclined surface 491 and the second inclined surface 492 are along the direction from the filter element locked position to the filter element unlocked position (i.e., Figure 4 (as shown in the clockwise direction) tilted in the opposite direction to the insertion direction of the filter element assembly 300.

[0097] By incorporating the filter element locking sleeve 490, dust and other impurities can be effectively prevented from falling onto the filter element rotating component 482, thus avoiding issues such as rotational jamming or unstable rotation speed. Furthermore, it prevents users from contacting the filter element rotating component 482, avoiding potential accidents during its rotation. In addition, the filter element locking sleeve 490 also surrounds the filter element housing 481 and the filter element rotating component 482, resulting in a cleaner appearance for the filter element housing assembly 400.

[0098] Preferably, such as Figure 3-4 As shown, the filter cartridge holder assembly 400 may further include a filter cartridge reset member 483. The filter cartridge reset member 483 may be connected between the filter cartridge holder body 481 and the filter cartridge rotating member 482. The filter cartridge reset member 483 may be used to return the filter cartridge rotating member 482 from the filter cartridge unlocked position to the filter cartridge locked position. Preferably, the filter cartridge reset member 483 may be a spring.

[0099] As described above, during the installation of the filter element assembly 300, the filter element rotating member 482 moves to the filter element unlock position, at which point the filter element reset member 483 can be in a state of significant compression or stretching. When the filter element assembly 300 is installed in place, that is, when the filter element locking part 360 passes over the filter element locking mating part 470 and moves to the bottom between the filter element locking mating part 470 and the filter element seat slot 410, the filter element reset member 483 can release its stored elastic potential energy, causing the filter element rotating member 482 to return to the filter element locked position. At this time, the filter element reset member 483 can be in a naturally extended state, or in a state of minor compression or stretching.

[0100] By setting the filter element reset component 483, when the filter element assembly 300 is installed in place, the filter element rotating component 482 can rotate to the filter element locking position by itself, reducing operation steps and improving the human-machine interaction.

[0101] Unless otherwise specified or obviously contradictory, the embodiments mentioned above in which the pump assembly 100 is connected to the pump seat assembly 200 and the embodiments in which the filter element assembly 300 is connected to the filter element seat assembly 400 are applicable to each other.

[0102] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front", "rear", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0103] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," and "above" are used herein to describe the spatial positional relationship between one or more components or features shown in the figures and other components or features. It should be understood that spatial relative terms include not only the orientation of the component as depicted in the figures but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0104] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, parts, components, and / or combinations thereof.

[0105] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.

[0106] The present invention has been described through the above embodiments. However, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit the invention to the scope of the described embodiments. Furthermore, those skilled in the art will understand that the present invention is not limited to the above embodiments, and many more variations and modifications can be made based on the teachings of the present invention, all of which fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
