[0009] According to some embodiments of the present invention, the connector forms a mating groove that is open in the axial direction, and the first locking part is configured as a first protrusion extending circumferentially on the inner peripheral wall of the mating groove; the end of the filter element is received in the mating groove, and the second locking part is configured as a second protrusion extending circumferentially on the end of the filter element.

[0010] According to some embodiments of the present invention, a filter channel extending axially and open at the end of the filter element is formed inside the filter element; a pipe plug extending axially is formed on the connector, a connector channel is formed inside the pipe plug, the pipe plug is received inside the filter channel and the connector channel is connected to the filter channel.

[0011] According to some embodiments of the present invention, the pipe plugs are configured as multiple, with one of them located at the axial center of the connector, and the remaining pipe plugs are circumferentially distributed around the axial center of the connector.

[0012] According to some embodiments of the present invention, the connector includes: a connector body on which the pipe plug is formed; a locking member rotatably disposed on one axial side of the connector body and having a first locking portion, the locking member having a through hole extending axially; wherein, the through holes are configured to be multiple corresponding to the pipe plugs, the pipe plugs being inserted one by one through the through holes, and at least one of the through holes extending circumferentially around the axial center of the connector.

[0013] According to some embodiments of the present invention, the connector has a limiting plug extending in the axial direction, the end of the filter element has a limiting hole opening in the axial direction, the limiting plug passes through the limiting hole, and the end diameter of the limiting plug is larger than the opening diameter of the filter channel.

[0014] According to some embodiments of the present invention, the filter assembly further includes: a first sealing member, which is fixedly disposed within the filter channel; and a second sealing member, which is movably disposed within the filter channel, and the second sealing member is movable relative to the first sealing member to engage or disengage with the first sealing member; wherein the pipe plug is adapted to push the second sealing member to move to disengage the engaged first sealing member from the second sealing member.

[0015] According to some embodiments of the present invention, the filter assembly further includes: an elastic member disposed within the filter channel and connected to the second seal, the elastic member being adapted to push the second seal to move so as to engage the separated first seal with the second seal.

[0016] According to some embodiments of the present invention, the end of the pipe plug is provided with a pin protruding outward along the axial direction, and the end of the second sealing member is formed with a groove recessed inward along the axial direction. The pin is adapted to be inserted into the groove and push the second sealing member to move axially.

[0017] According to some embodiments of the present invention, the peripheral wall of the filter channel is formed with an annular groove, at least a portion of the first seal is embedded in the annular groove, and at least another portion of the first seal extends out of the annular groove.

[0018] In summary, according to the filter assembly of this utility model embodiment, the connector has a first locking portion, and the end of the filter element has a second locking portion. The second locking portion can selectively move relative to the first locking portion to lock or unlock with the first locking portion. Therefore, after the filter element is installed in place, by controlling the movement of the second locking portion relative to the first locking portion to lock with the first locking portion, the filter element can be fixed, ensuring a stable connection between the filter element and the connector under normal use. Similarly, when it is necessary to disassemble the filter element, by controlling the movement of the second locking portion relative to the first locking portion to unlock with the first locking portion, the filter element can be easily separated from the connector. The connector has a mating groove that is open in the axial direction. The first locking portion is constructed as a first protrusion extending circumferentially on the inner peripheral wall of the mating groove. The end of the filter element is received in the mating groove, and the second locking portion is constructed as a second protrusion extending circumferentially on the end of the filter element. Therefore, during assembly, the end of the filter element is first aligned with the mating groove of the connector and slowly pushed in until the end of the filter element is received in the mating groove. During the pushing process, the second protrusion at the end of the filter element is axially offset from the first protrusion on the inner circumferential wall of the mating groove. The second protrusion slides along the inner circumferential wall of the mating groove until the end of the filter element is completely received within the mating groove. Subsequently, by rotating the filter element, the second protrusion gradually aligns with the first protrusion circumferentially and comes into close contact, forming an effective locking structure. The assembly process is simple and intuitive, improving the convenience and efficiency of operation. A filter channel extending axially and opening at the end of the filter element is formed inside the filter element. The filter channel starts from one end of the filter element and extends to the other end, opening at the end of the filter element, allowing the organic clothing treatment agent to smoothly enter the filter element, flow through the filter channel and be effectively filtered, and then leave the filter element. An axially extending pipe plug is formed on the connector, and a connector channel is formed inside the pipe plug. The connector channel is a passage for the organic clothing treatment agent to flow inside the connector, responsible for introducing the organic clothing treatment agent from the outside of the connector into the inside, or transporting the organic clothing treatment agent from the inside to the outside. The tubing plug is housed within the filter channel, connecting the connector channel to the filter channel. Once the tubing plug is inserted into the filter channel, the organic laundry detergent can enter the filter channel of the filter element from the outside of the connector through the connector channel for necessary filtration. After filtration, the purified organic laundry detergent can flow out through the other end of the filter element and re-enter the connector, facilitating the delivery of the purified organic laundry detergent to the washing tub of the dry cleaning equipment.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In related technologies, filter components suffer from inconvenient installation and disassembly, causing difficulties in equipment maintenance and filter replacement. Furthermore, the unstable connection between the filter element and the connector can easily lead to leakage of organic clothing treatment agents during the filtration process, affecting the overall performance and stability of the filter component.

[0035] The following is for reference. Figures 1-3 The filter component 1 according to an embodiment of the present invention is described.

[0036] like Figures 1-3 As shown, the filter assembly 1 according to this utility model is used in dry cleaning equipment. The filter assembly 1 is used to filter organic clothing treatment agents to achieve purification of the organic clothing treatment agents.

[0037] Organic garment cleaners are organic solvents containing organic compounds, used in dry cleaning to clean clothes. Unlike water-based detergents, organic garment cleaners effectively dissolve oily stains while avoiding the damage water can cause to certain fabrics. Organic garment cleaners achieve highly efficient cleaning during dry cleaning while protecting the structure and color of the clothing fibers. Examples of organic garment cleaners include tetrachloroethylene and hydrocarbon solvents.

[0038] The filter assembly 1 includes a connector 11 and a filter element 12. The connector 11 is used to connect the filter element 12 to other pipelines, allowing used organic laundry detergent containing impurities to be introduced into the filter element 12 through other pipelines, where the filter element 12 filters the organic laundry detergent. By providing the connector 11, the filter element 12 can be installed and removed according to actual needs, improving the convenience of assembly and maintenance.

[0039] The end of the filter element 12 is connected to the connector 11 to install the filter element 12, so that the filter element 12 can receive organic clothing treatment agents delivered by other pipelines and filter the organic clothing treatment agents.

[0040] The connector 11 has a first locking portion 1121, and the end of the filter element 12 has a second locking portion 121. The second locking portion 121 can selectively move relative to the first locking portion 1121 to lock or unlock with the first locking portion 1121. Therefore, after the filter element 12 is installed in place, by controlling the second locking portion 121 to move relative to the first locking portion 1121 to lock with the first locking portion 1121, the filter element 12 can be fixed, ensuring a stable connection between the filter element 12 and the connector 11 under normal use. Similarly, when it is necessary to disassemble the filter element 12, by controlling the second locking portion 121 to move relative to the first locking portion 1121 to unlock with the first locking portion 1121, the filter element 12 can be easily separated from the connector 11.

[0041] Therefore, according to the filter assembly 1 of this utility model, the cooperation between the first locking part 1121 and the second locking part 121 not only simplifies the installation and disassembly process of the filter element 12, but also ensures the tight connection between the filter element 12 and the connector 11 during use, thus guaranteeing the overall performance and stability of the filter assembly 1.

[0042] It should be noted that the filter assembly 1 according to this utility model does not limit the way the second locking part 121 moves relative to the first locking part 1121. For example, the second locking part 121 can be locked or unlocked with the first locking part 1121 by rotation, sliding or other forms of mechanical action to adapt to different usage conditions.

[0043] According to some embodiments of this utility model, such as Figure 2 and Figure 3As shown, the second locking part 121 can be selectively rotated relative to the first locking part 1121 until it abuts against the first locking part 1121 in the axial direction of the filter element 12 to lock it in place. Therefore, when it is necessary to install and lock the filter element 12 onto the connector 11, the second locking part 121 is controlled to rotate relative to the first locking part 1121 until the second locking part 121 abuts against the first locking part 1121 in the axial direction of the filter element 12. At this time, the second locking part 121 and the first locking part 1121 are in close physical contact and form a barrier in the axial direction of the filter element 12, effectively preventing the filter element 12 from moving in the axial direction, thereby achieving a firm connection between the filter element 12 and the connector 11.

[0044] The second locking part 121 can be selectively rotated relative to the first locking part 1121 until it is axially misaligned with the first locking part 1121 to unlock. Therefore, when the filter element 12 needs to be disassembled for replacement or maintenance, the operation opposite to the locking process is performed, and the second locking part 121 rotates relative to the first locking part 1121 until the second locking part 121 is axially misaligned with the first locking part 1121, thereby releasing the physical contact between the second locking part 121 and the first locking part 1121, thus allowing the filter element 12 to be easily separated from the connector 11.

[0045] Locking and unlocking are achieved by rotating the second locking part 121 relative to the first locking part 1121, which not only simplifies the installation and disassembly process of the filter element 12, but also significantly improves the reliability and ease of use of the filter assembly 1.

[0046] It should be noted that the second locking part 121 can be rotated relative to the first locking part 1121 by rotating the filter element 12. This allows the filter element 12 to be held directly and rotated clockwise or counterclockwise to easily complete the locking or unlocking action without the need for additional tools or complicated operating steps, thus enhancing the user experience and improving operating efficiency.

[0047] According to some embodiments of this utility model, such as Figures 1-3As shown, the connector 11 has an axially open mating groove. The first locking part 1121 is constructed as a first protrusion extending circumferentially on the inner circumferential wall of the mating groove. The end of the filter element 12 is received within the mating groove, and the second locking part 121 is constructed as a second protrusion extending circumferentially on the end of the filter element 12. Therefore, during assembly, the end of the filter element 12 is first aligned with the mating groove of the connector 11 and slowly pushed in until the end of the filter element 12 is received within the mating groove. During the pushing process, the second protrusion at the end of the filter element 12 is axially offset from the first protrusion on the inner circumferential wall of the mating groove, and the second protrusion slides along the inner circumferential wall of the mating groove until the end of the filter element 12 is completely received within the mating groove. Subsequently, by rotating the filter element 12, the second protrusion gradually aligns with and comes into close contact with the first protrusion circumferentially, forming an effective locking structure. The assembly process is simple and intuitive, improving the convenience and efficiency of operation.

[0048] According to some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, a filter channel 122 is formed inside the filter element 12, extending axially and opening at the end of the filter element 12. The filter channel 122 starts from one end of the filter element 12 and extends to the other end, opening at the end of the filter element 12, so that the organic clothing treatment agent can smoothly enter the filter element 12, flow through the filter channel 122 and be effectively filtered, and then leave the filter element 12.

[0049] A pipe plug 1111 extending axially is formed on the connector 11, and a connector flow channel 1111a is formed inside the pipe plug 1111. The connector flow channel 1111a is a channel through which the organic laundry detergent can flow inside the connector 11, responsible for introducing the organic laundry detergent from the outside of the connector 11 into the inside, or transporting the organic laundry detergent from the inside to the outside. The pipe plug 1111 is housed within the filter flow channel 122 and communicates with the filter flow channel 122. When the pipe plug 1111 is inserted into the filter flow channel 122, the organic laundry detergent can enter the filter flow channel 122 of the filter element 12 from the outside of the connector 11 through the connector flow channel 1111a for necessary filtration. After filtration, the pure organic laundry detergent can flow out through the other end of the filter element 12 and re-enter the interior of the connector 11, so as to facilitate the delivery of the pure organic laundry detergent to the washing tub of the dry cleaning equipment.

[0050] According to some embodiments of this utility model, such as Figures 1-3 As shown, there are multiple pipe plugs 1111, one of which is located at the axial position of the connector 11, and the remaining pipe plugs 1111 are distributed circumferentially around the axial position of the connector 11.

[0051] By constructing multiple pipe plugs 1111, multiple delivery paths can be used to deliver the organic clothing treatment agent, enhancing the delivery capacity and accelerating the delivery speed. Correspondingly, multiple filter channels 122 corresponding to the pipe plugs 1111 are formed within the filter element 12, each filter channel 122 being connected to the connector channel 1111a of one pipe plug 1111. When the organic clothing treatment agent enters the filter element 12 through different pipe plugs 1111, it can flow into its respective filter channel 122 for filtration, improving the filtration efficiency and ensuring thorough purification of the organic clothing treatment agent on each delivery path. Furthermore, the presence of multiple pipe plugs 1111 and filter channels 122 makes the overall structure of the filter element 12 more compact and efficient, achieving a larger filtration area and higher filtration rate within a limited volume.

[0052] One of the multiple tubing plugs 1111 is located at the axial position of the connector 11. This not only ensures that the tubing plug 1111 at the axial position can efficiently receive and dispense organic garment treatment agent, but also provides a reference for the layout of the remaining tubing plugs 1111. The axial position refers to the geometric center of the connector 11, that is, the point where all points are equidistant from the outer surface of the connector 11. The remaining tubing plugs 1111 are circumferentially distributed around the axial position of the connector 11, optimizing space utilization and making the layout of the tubing plugs 1111 more compact and efficient. Each tubing plug 1111 undertakes a specific delivery task, working together to meet the dry cleaning equipment's need for multi-path, high-efficiency delivery of organic garment treatment agent.

[0053] According to some embodiments of this utility model, such as Figures 1-3 As shown, the connector 11 includes a connector body 111 and a locking member 112. A tubing plug 1111 is formed on the connector body 111 for conveying organic clothing treatment agent. The locking member 112 is rotatably disposed on one axial side of the connector body 111 and has a first locking portion 1121 for engaging with a second locking portion 121 to fix the connector 11 to the filter element 12. During assembly, after the tubing plug 1111 on the connector body 111 is inserted into the filter channel 122, rotating the filter element 12 will cause the connector body 111 to rotate synchronously. Because the locking member 112 is rotatably disposed on one axial side of the connector body 111, when the filter element 12 is rotated and the connector body 111 rotates synchronously, the locking member 112 does not obstruct the rotation of the connector body 111. Furthermore, by setting the first locking part 1121 on the locking member 112, during the rotation of the filter element 12, the relative position of the second locking part 121 on the filter element 12 and the first locking part 1121 on the locking member 112 changes, thereby achieving the locking of the second locking part 121 and the first locking part 1121.

[0054] The locking member 112 has an axially extending through hole 1122. Multiple through holes 1122 are configured to correspond to the pipe plugs 1111, with each pipe plug 1111 passing through one of the through holes 1122. This allows the pipe plugs 1111 to pass through the locking member 112 and be inserted into the filter channel 122, thereby achieving communication between the connector channel 1111a and the filter channel 122, enabling the organic clothing treatment agent to flow between the connector 11 and the filter element 12. When the connector body 111 rotates under the influence of the filter element 12, the pipe plug 1111 located at the axial center of the connector 11 rotates on its own axis, while the remaining pipe plugs 1111, circumferentially distributed around the axial center of the connector 11, revolve within their respective through holes 1122 as the connector body 111 rotates, maintaining a stable connection with the filter channel 122. Therefore, at least one through hole 1122 extends circumferentially around the axial position of the connector 11, so that the through hole 1122 extending circumferentially around the axial position can adapt to the trajectory change of the pipe plug 1111 during revolution, ensuring that the locking member 112 will not hinder the rotation of the connector body 111, thereby realizing the effective locking or unlocking of the second locking part 121 and the first locking part 1121.

[0055] According to some embodiments of this utility model, a limiting plug extending axially is formed on the connector 11, and a limiting hole opening axially is formed at the end of the filter element 12. During assembly, the limiting hole at the end of the filter element 12 is aligned with the limiting plug on the connector 11. After the limiting plug passes through the limiting hole, a preliminary connection is established between the filter element 12 and the connector 11, thus achieving assembly positioning of the filter element 12 and the connector 11 and improving assembly efficiency. The end diameter of the limiting plug is larger than the opening diameter of the filter channel 122, therefore the limiting plug can only pass through the limiting hole and not through the filter channel 122, thereby effectively avoiding misalignment problems that may occur during the assembly of the filter element 12.

[0056] According to some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the filter assembly 1 also includes a first seal 13 and a second seal 14. The first seal 13 is fixedly disposed within the filter channel 122, while the second seal 14 is movably disposed within the filter channel 122. The second seal 14 moves relative to the first seal 13 to engage or disengage with the first seal 13. When the second seal 14 engages with the first seal 13, the first seal 13 and the second seal 14 together effectively seal the filter channel 122. This ensures the airtightness of the filter channel 122 when the filter element 12 is not connected to the connector 11, preventing unnecessary loss of organic clothing treatment agent during filter element 12 replacement or maintenance, and also protecting the interior of the filter assembly 1 from external contamination.

[0057] The connector 1111 is adapted to move the second seal 14 to separate the engaged first seal 13 from the second seal 14. During assembly, as the connector 1111 is inserted into the filter channel 122, its tip gradually approaches and eventually contacts the second seal 14. As the connector 1111 continues to penetrate, it applies a backward thrust to the second seal 14, causing it to slide axially backward within the filter channel 122, gradually disengaging it from its engagement with the first seal 13 until they are completely separated. After separation, the first seal 13 and the second seal 14 no longer obstruct fluid flow, and the connector channel 1111a within the connector 1111 communicates with the filter channel 122. At this point, the organic garment treatment agent can freely enter the filter channel 122 through the connector channel 1111a. By pushing the second seal 14 with the pipe plug 1111 to separate the engaged first seal 13 from the second seal 14, the filter channel 122 can be quickly switched between sealing and flow, making operation convenient.

[0058] According to some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the filter assembly 1 also includes an elastic element 15, which is disposed within the filter channel 122 and connected to the second seal 14. The elastic element 15, utilizing its elasticity, continuously applies a forward thrust to the second seal 14. When the filter element 12 is disconnected from the connector 11, or when the filter element 12 needs to be replaced or maintained, the thrust causes the second seal 14 to slide axially forward within the filter channel 122 until the second seal 14 re-engages tightly with the first seal 13. This ensures the airtightness of the filter channel 122 when the filter element 12 is not connected, effectively preventing the loss of organic clothing treatment agents. It also provides necessary protection for the interior of the filter assembly 1, preventing the intrusion of external pollutants.

[0059] By incorporating the elastic element 15, not only is automatic engagement of the first seal 13 and the second seal 14 achieved when needed, but the operation process is also simplified, improving the automation level of the filter assembly 1 and the user experience. Furthermore, the continuous elastic force of the elastic element 15 ensures the stability and durability of the sealing effect, maintaining an effective seal on the filter channel 122 for an extended period.

[0060] According to some embodiments of this utility model, such as Figures 1-3As shown, the end of the pipe plug 1111 has a pin 1111b protruding outward along the axial direction, and the end of the second seal 14 has a groove recessed inward along the axial direction. The pin 1111b is adapted to insert into the groove and push the second seal 14 to move axially. When the pipe plug 1111 is inserted into the filter channel 122, the pin 1111b can be inserted into the groove and, using this as a fulcrum, effectively push the second seal 14 to move in the axial direction. Through the tight fit between the pin 1111b and the groove, the pipe plug 1111 can achieve a stable interaction with the second seal 14, which not only realizes the effective pushing of the pipe plug 1111 onto the second seal 14, but also ensures the accuracy and reliability of the pushing process. Through the pushing action of the pin 1111b, the precise separation between the second seal 14 and the first seal 13 is achieved, making the operation simple and efficient.

[0061] According to some embodiments of this utility model, such as Figure 2 As shown, the peripheral wall of the filter channel 122 has an annular groove 1221. The annular groove 1221 provides space to accommodate at least a portion of the first seal 13, allowing the seal to be securely installed on the peripheral wall of the filter channel 122, preventing it from easily falling off or shifting. At least a portion of the first seal 13 is embedded in the annular groove 1221. By embedding at least a portion of the seal into the annular groove 1221, accurate positioning and fixation of the seal can be achieved, helping to ensure the stability of the seal's position in the filter channel 122, thereby improving the sealing effect. At least another portion of the first seal 13 extends out of the annular groove 1221. The portion of the first seal 13 extending out of the annular groove 1221 is used to engage with the second seal 14 to jointly seal the filter channel 122.

[0062] The following is a brief description of the dry cleaning equipment according to this utility model.

[0063] The dry cleaning equipment according to this utility model includes the filter component 1 in any of the above embodiments.
