[0020] The scale inhibitor module according to a second aspect embodiment of the present invention is briefly described below.

[0021] The scale inhibitor module according to the present invention includes the end cap assembly described in any of the above embodiments. Since the scale inhibitor module according to the present invention is provided with the end cap assembly described in the above embodiments, the scale inhibitor module is easy to assemble and has a stable connection, is not prone to leakage, and is easy to disassemble. The scale inhibitor module is less likely to have residual water inside, is cleaner, and provides a better user experience.

[0022] The following is a brief description of a garment processing apparatus according to a third aspect embodiment of the present invention.

[0023] The garment treatment device according to the present invention includes the scale inhibition module described in any of the above embodiments.

[0024] In summary, the end cap assembly of this invention is manufactured as two separate parts. The cap body is connected to the scale inhibition module, and the filter screen is located inside the scale inhibition module. The connector connects the cap body and the filter screen. This end cap assembly is easy to industrially form and process. Furthermore, the cuboid shape of the cap body makes it easy for users to grip and open, improving the user experience. The connector is fixed to the cap body through a two-stage snap-fit ​​mechanism, ensuring the connector will not slip off. The connection process is simple and stable. The connector can be connected to the cap body through the existing threaded connection between the cap body and the scale inhibition module, eliminating the need for a separate connector installation structure, thus simplifying manufacturing. Three limiting members form a stable triangle, and deformation notches are formed on both sides of the limiting members. This allows the limiting members to deform during connector rotation, causing the positioning protrusion to engage with the positioning groove, thereby fixing the connector to the cap body. An interference fit is provided. The positioning groove and positioning protrusion prevent loosening between the limiting component and the first thread, and also position the installation angle of the connector. The positioning protrusion and positioning groove have a simple structure, making them easy to process. At the same time, the positioning groove is provided with a guide slope, which makes the installation of the connector faster and easier for the user to operate. The first thread is distributed axially and intermittently, which is conducive to the forming process of the cover mold, making it easy to process. Residual water can flow out through the installation channel, making cleaning convenient and preventing the growth of bacteria. The installation channel also makes it easy to adjust the installation angle of the limiting component during installation, reducing the resistance of the limiting component installation and making the installation of the connector easier. By setting positioning posts on the cover and positioning ribs on the connector, the connection stability between the connector and the cover can be improved, and the rotation or loosening of the limiting component can be prevented. The installation angle of the connector can also be positioned. The staggered arrangement of the installation channel and the positioning protrusion or the staggered arrangement of the limiting component and the positioning groove ensures that the positioning protrusion and the positioning groove do not interfere with the limiting component extending into the installation channel.

[0047] Washing machines typically have a scale-inhibiting module for filtering wash water. The scale-inhibiting module has an end cap assembly that facilitates opening and closing of the internal cavity. In existing designs, the end cap assembly can also cooperate with the filter screen to fix the position of the filter screen inside the scale-inhibiting module. However, the part of the end cap assembly that cooperates with the filter screen has a complex structure. This part is usually integrally formed with the end cap assembly and is not easy to process and manufacture.

[0048] The following is for reference. Figures 1-12 An end cap assembly 100 for a scale inhibition module 300 according to an embodiment of the present invention is described.

[0049] like Figure 4 As shown, the end cap assembly 100 according to the present invention includes: a cap body 110 and a connector 120. The cap body 110 is adapted to cooperate with the scale inhibition module 300; the connector 120 is disposed on the side of the cap body 110 facing the scale inhibition module 300, and the connector 120 is provided with a filter mounting position 120a for mounting a filter screen 200. After the cap body 110 is engaged with the scale inhibition module 300, the filter mounting position 120a is received within the scale inhibition module 300. Specifically, the end cap assembly 100 is installed at one end of the scale inhibition module 300. The scale inhibition module 300 has a chamber inside. The cover 110 can open and close the chamber after cooperating with the scale inhibition module 300. The filter screen 200 is installed in the chamber. The cover 110 and the filter screen 200 are connected by a connector 120. The connector 120 cooperates with both the cover 110 and the filter screen 200. The filter screen 200 is located at the filter screen mounting position 120a of the connector 120. The connector 120 and the cover 110 are two separate parts. When assembling the end cap assembly 100, the connector 120 and the cover 110 can be welded or bonded into one piece, or the connector 120 and the cover 110 can be detachably assembled. When assembling the scale inhibition module 300, the end cap assembly 100 can be assembled first, the connector 120 can be connected to the cover 110, the filter screen 200 can be installed in the filter screen mounting position 120a, and finally the end cap assembly 100 can be connected to the scale inhibition module 300.

[0050] In the end cap assembly 100 of the present invention, the connector 120 cooperates with the cap body 110 and the filter screen 200 respectively to connect the cap body 110 and the filter screen 200. The connector 120 and the cap body 110 are processed into two separate parts during production, which makes it easy to industrially form the end cap assembly 100 and easy to process.

[0051] According to some embodiments of the present invention, a first mating part is provided on the cover 110, and a second mating part is provided on the connector 120 connected to the first mating part. The first mating part and the second mating part are connected by at least one of the following connection methods: snap-fit, threaded fit, adhesive bonding, and welding. Specifically, the connector 120 and the cover 110 are connected by the first mating part and the second mating part. Using at least one of the above four connection methods to connect the connector 120 and the cover 110 can ensure the structural stability of the end cap assembly 100. In some embodiments, when assembling the end cap assembly 100, the connector 120 and the cover 110 can be welded or bonded into a single piece, and the structure of the end cap assembly 100 is stable. In other embodiments, the connector 120 and the cover 110 can be detachably assembled by snap-fit ​​or threaded fit, which facilitates the assembly or disassembly of the scale inhibitor module 300 by the operator. It is understood that the connection between the connector 120 and the cover 110 can also be a combination of several connection methods, such as snap-fit, threaded fit, bonding, and welding. In some embodiments, the connector 120 can be radially and axially limited by a threaded fit, and then the connector 120 can be circumferentially limited by a snap-fit. The connection between the connector 120 and the cover 110 is not limited to a combination of snap-fit ​​and threaded fit, but can also be other combinations of the above four connection methods, as long as a stable connection between the connector 120 and the cover 110 is ensured.

[0052] More specifically, a first mating portion is disposed on the cover 110, and the connector 120 has a side facing the filter screen 200, on which a filter screen mounting position 120a is disposed. The connector 120 also has another side directly opposite the side where the filter screen mounting position 120a is disposed. A peripheral wall is formed between the one side and the other side of the connector 120, and the peripheral wall of the connector 120 includes an outer peripheral wall and an inner peripheral wall. In some embodiments, a second mating portion is disposed on the peripheral wall of the connector 120. The connector 120 engages with the cover 110 via a second mating part on its peripheral wall, facilitating the assembly of the end cap assembly 100 by workers and making it easy to operate. In some embodiments, the second mating part is located on the other side of the connector 120, and the two sides of the connector 120 facing each other are respectively connected to the filter screen 200 and the cover 110, making the connection between the filter screen 200 and the cover 110 stable. In other embodiments, the second mating part is provided on the other side of the connector 120 and on the peripheral wall of the connector 120.

[0053] According to some embodiments of the present invention, such as Figure 2 , Figure 4 , Figure 5 , Figure 8 As shown, a receiving groove 110a is formed within the cover 110. The receiving groove 110a is sleeved on at least a portion of the outer periphery of the scale inhibition module 300 and is adapted to accommodate at least a portion of the connector 120. A first thread 110d is formed on the inner wall of the receiving groove 110a. A limiting member 122 is provided on the outer peripheral wall of the connector 120. The first thread 110d cooperates with the scale inhibition module 300 and the limiting member 122 respectively to restrict the axial movement of the connector 120 and the cover 110. Specifically, a second thread 300d is provided on at least a portion of the outer periphery of the scale inhibition module 300. The second thread 300d is adapted to thread-fit with the first thread 110d on the inner wall of the receiving groove 110a of the cover 110, thereby realizing the cooperation between the scale inhibition module 300 and the end cap assembly 100. A portion of the connector 120 is located inside the receiving groove 110a to mate with the cover 110, and another portion of the connector 120 is located inside the scale inhibition module 300 to mate with the filter screen 200. The connector 120 and the cover 110 are connected by a first thread 110d and a limiting member 122. When assembling the end cap assembly 100, the first thread 110d is first engaged with the limiting member 122 to restrict the radial movement of the connector 120. At this time, the connector 120 is engaged with the cover 110. The connector 120 can engage with the first thread 110d and rotate circumferentially to adjust the axial position of the connector 120. Then, the first thread 110d is engaged with the second thread 300d to restrict the axial movement of the connector 120. At this time, the scale inhibition module 300 is engaged with the cover 110, and the axial, circumferential, and radial movements of the connector 120 are all restricted, thereby completing the engagement of the scale inhibition module 300 and the end cap assembly 100.

[0054] More specifically, such as Figures 4-5 As shown, at least a portion of the outer peripheral wall of the connector 120 can contact at least a portion of the inner wall of the receiving groove 110a. The at least portion of the outer peripheral wall of the connector 120 is a limiting member 122, and the at least portion of the inner wall of the receiving groove 110a is a first thread 110d. The limiting member 122 and the first thread 110d can have various mating methods. In some embodiments of the present invention, the first mating portion on the cover 110 is constructed as the first thread 110d, and the second mating portion on the connector 120 is constructed as the limiting member 122. The limiting member 122 and the first thread 110d are connected to the connector 120 and the cover 110 by a snap-fit ​​and / or threaded engagement. For example, in some embodiments, the limiting member 122 is configured as a third thread. First, the connector 120 and the cover 110 are threadedly engaged by the limiting member 122 and the first thread 110d. At this time, at least a portion of the connector 120 is located in the receiving groove 110a. Then, the scale inhibition module 300 and the cover 110 are threadedly engaged by the second thread 300d and the first thread 110d. At this time, the end cap assembly 100 is sleeved on one end of the scale inhibition module 300. In other embodiments... In one example, the limiting member 122 is constructed as a limiting protrusion. The outer peripheral wall of the limiting protrusion on the connecting member 120 can undergo slight deformation so that the limiting member 122 extends into the bottom end of the receiving groove 110a and abuts against the bottom end of the first thread 110d. The limiting member 122 and the first thread 110d are engaged by a snap-fit. In other embodiments, the limiting member 122 is constructed as a combination of a third thread and a limiting protrusion. The limiting member 122 and the first thread 110d can first move to the bottom end of the first thread 110d through the engagement between the first thread 110d and the third thread, and then the limiting protrusion abuts against the bottom end of the first thread 110d. It is understood that the engagement method between the limiting member 122 and the first thread 110d is not limited to a snap-fit ​​engagement and / or a threaded engagement, but can also be other engagement methods that facilitate the connection between the connecting member 120 and the cover 110. The connector 120 can be connected to the cover 110 through the existing threaded connection between the cover 110 and the scale inhibition module 300. There is no need to set up a separate structure for installing the connector 120. The structure is simple and easy to process. Furthermore, the operation of assembling the connector 120 with the cover 110 and assembling the end cap assembly 100 with the scale inhibition module 300 is simple, time-saving and labor-saving.

[0055] According to some embodiments of the present invention, such as Figures 6-7As shown, the limiting member 122 is constructed as multiple limiting protrusions protruding from the outer peripheral wall of the connector 120, and the limiting protrusions are spaced apart on the outer periphery of the connector 120. Specifically, the limiting member 122 is provided to protrude from the outer peripheral wall of the connector 120, and the limiting member 122 is constructed as limiting protrusions, each limiting protrusion being spaced apart from each other. When the limiting protrusion extends into the bottom end of the receiving groove 110a and abuts against the bottom end of the first thread 110d, a snap-fit ​​engagement is achieved between the limiting protrusion and the first thread 110d. The limiting protrusion has a simple structure and is easy to manufacture. The engagement between the connector 120 and the cover 110 is achieved through the snap-fit ​​engagement between the limiting protrusion and the first thread 110d, which is simple and easy to operate.

[0056] According to some embodiments of the present invention, such as Figures 6-7 As shown, the number of limiting members 122 is odd, and the outer peripheral wall of the connector 120 is provided with deformation notches 123 on both sides of the circumferential direction of the limiting members 122. Specifically, the connector 120 and the cover 110 are engaged with the first thread 110d through the limiting members 122. The number of limiting members 122 is odd, for example, there can be three or five limiting members 122. An odd number of feet results in a stable structure. Preferably, there are three limiting members 122, and the triangle shape is beneficial to the stability of the structure. More specifically, deformation notches 123 are formed on both sides of the limiting member 122, which facilitates the deformation of the limiting member 122 when it is engaged with the first thread 110d so that it can enter the designated position and then be restored and fixed. The length of the deformation notch 123 is the same as the length of the limiting member 122, and the width of each deformation notch 123 is not greater than the width of the limiting member 122, so as to prevent the limiting member 122 from being unable to be restored and fixed after being difficult to deform or excessively deformed. In addition, the number of limiting members 122 is no more than 5, so as to avoid multiple deformation notches 123 affecting the strength of the connecting member 120 at the location of the limiting member 122.

[0057] In the prior art, the part of the end cap assembly 100 that cooperates with the filter screen 200 has a complex structure, is prone to residual washing water, easily breeds bacteria, and is not easy to clean.

[0058] According to some embodiments of the present invention, such as Figure 8As shown, the inner wall of the receiving groove 110a is provided with an installation channel 110b that breaks the first thread 110d in the axial direction. The installation channel 110b is suitable for guiding the limiting member 122. Specifically, the first thread 110d is formed on the inner wall of the receiving groove 110a and the first thread 110d is axially discontinuously distributed, which is beneficial to the molding process of the cover 110 and facilitates processing. In addition, the first thread 110d of the cover 110 is prone to residual washing water. The discontinuity of the axially discontinuous thread is the installation channel 110b. The residual water in the gap of the first thread 110d can flow out through the installation channel 110b, which is convenient for cleaning and does not easily breed bacteria. At the same time, the discontinuous thread also makes it easy to adjust the installation angle of the limiting member 122 when installing the limiting member 122 of the connector 120, reducing the resistance to the installation of the limiting member 122 and making the installation easy.

[0059] In some embodiments of the present invention, such as Figures 8-9 As shown, there are multiple limiting members 122 and multiple installation channels 110b. The number of installation channels 110b is not less than the number of limiting members 122. Multiple limiting members 122 extend into the bottom wall of the receiving groove 110a through different installation channels 110b.

[0060] In some embodiments of the present invention, such as Figures 8-9 As shown, there are three limiting members 122 and four mounting channels 110b. The four mounting channels 110b divide the first thread 110d at equal distances. The included angle between any two adjacent mounting channels 110b is a right angle. Two limiting members 122 are set directly opposite the center of the cross section of the connector 120. The distance from the third limiting member 122 to the two opposite limiting members 122 is equal. The minimum included angle between any two adjacent limiting members 122 is a right angle. The limiting members 122 can extend into the bottom wall of the receiving groove 110a along the mounting channels 110b.

[0061] In some embodiments of the present invention, since the inside of the receiving groove 110a is not easy to clean, the cover 110 and the connector 120 are connected to form a sealing structure, which can seal the receiving groove 110a of the cover 110 to prevent washing water from entering the receiving groove 110a and avoid washing water residue. In other embodiments, after the cover 110 and the connector 120 are connected, a sealing element is provided at one end of the connector 120 facing the inside of the scale inhibition module 300. When the scale inhibition module 300 and the end cap assembly 100 are engaged, the sealing element is provided between the scale inhibition module 300 and the end cap assembly 100, which can form a sealing effect on the end cap assembly 100 to prevent washing water from entering the end cap assembly 100 and remaining. In other embodiments, the sealing structure is formed on the peripheral wall of the connector 120. After the cover 110 and the connector 120 are engaged, the sealing effect on the receiving groove 110a can be achieved.

[0062] According to some embodiments of the present invention, such as Figures 7-8 As shown, a first positioning part is provided on the cover 110, and a second positioning part is provided on the connector 120 to cooperate with the first positioning part. After the first positioning part and the second positioning part cooperate, the cover 110 and the connector 120 are locked to restrict the circumferential movement of the connector 120 and the cover 110. Specifically, after the first thread 110d engages with the limiting member 122, the radial movement of the connecting member 120 is restricted. At this time, the connecting member 120 can only rotate in the circumferential direction to adjust its axial position. A first positioning part and a second positioning part are provided. When the connecting member 120 rotates a certain angle in the circumferential direction, the first positioning part engages with the second positioning part. At this time, the connecting member 120 can no longer rotate. The circumferential rotation of the connecting member 120 is restricted, so the limiting member 122 cannot move in the axial direction. Through the engagement between the limiting member 122 and the first thread 110d, and the engagement between the first positioning part and the second positioning part, the connecting member 120 is positioned in three directions. The connecting member 120 cannot move, the engagement between the connecting member 120 and the cover 110 is stable, and the connecting member 120 will not slip off from the cover 110.

[0063] According to some embodiments of the present invention, such as Figures 7-8 As shown, one of the first positioning part and the second positioning part has a positioning protrusion 121 extending axially, and the other of the first positioning part and the second positioning part has a positioning groove 111 extending axially. Specifically, when assembling the end cap assembly 100, the limiting member 122 of the connector 120 is first engaged with the first thread 110d. At this time, the radial movement of the connector 120 is restricted. Then, the connector 120 is rotated until the positioning protrusion 121 engages with the positioning groove 111. At this time, the connector 120 cannot continue to rotate, and the circumferential movement of the connector 120 is restricted, as is the axial movement. The connector 120 is fixed to the cover body 110 through two snap-fit ​​engagements. The positioning groove 111 and the positioning protrusion 121 can prevent the engagement between the limiting member 122 and the first thread 110d from loosening, and can also position the installation angle of the connector 120. The structure of the positioning protrusion 121 and the positioning groove 111 is simple and easy to process.

[0064] In some embodiments of the present invention, such as Figures 7-8 As shown, the first positioning part is disposed on the bottom wall of the receiving groove 110a of the cover 110 and extends in a direction away from the bottom wall of the receiving groove 110a. The second positioning part is disposed on the bottom wall of the connector 120 and extends in a direction towards the bottom wall of the receiving groove 110a. When the connector 120 moves to the point where the first positioning part and the second positioning part cooperate, the connector 120 can no longer rotate.

[0065] In some embodiments of the present invention, the first positioning part and the second positioning part are interference fit to prevent slippage between the positioning protrusion 121 and the positioning groove 111. Since the limiting member 122 has deformation notches 123 on both sides, the limiting member 122 can undergo slight deformation while the first positioning part and the second positioning part are engaged, and then recover after the first positioning part and the second positioning part are engaged.

[0066] In some embodiments of the present invention, such as Figures 7-8 As shown, the first mating part on the cover 110 is the positioning groove 111 and the first thread 110d, and the second mating part on the connector 120 is the positioning protrusion 121 and the limiting member 122. The mating method between the first mating part and the second mating part is a combination of two snap-fit ​​mating methods. Specifically, when assembling the end cap assembly 100, the limiting member 122 of the connector 120 is first inserted into the bottom wall of the receiving groove 110a along the installation channel 110b. At this time, the connector 120 is rotated until the limiting member 122 is misaligned with the installation channel 110b and abuts against the bottom wall of the first thread 110d. The radial movement of the connector 120 is restricted. Then, the connector 120 is rotated until the positioning protrusion 121 engages with the positioning groove 111. At this time, the connector 120 cannot continue to rotate. The circumferential movement of the connector 120 is restricted and the axial movement is restricted. The connector 120 is fixed to the cover 110 through two snap-fit ​​mating methods. The simple mating method between the first mating part and the second mating part makes the mating between the connector 120 and the cover 110 convenient and stable.

[0067] According to some embodiments of the present invention, such as Figure 8 As shown, a positioning post 110c protruding towards the connector 120 is formed in the receiving groove 110a. The positioning post 110c is adapted to abut against the connector 120, and a positioning groove 111 is formed on the positioning post 110c. Specifically, the positioning post 110c is disposed on the bottom wall of the receiving groove 110a of the cover 110 and extends in a direction away from the bottom wall of the receiving groove 110a. The connector 120 and the cover 110 are engaged by the limiting member 122 and the first thread 110d, and then by the positioning protrusion 121 and the positioning groove 111, which makes the engagement more stable. Furthermore, the positioning groove 111 is disposed on the positioning post 110c, which can improve the connection stability between the connector 120 and the cover 110.

[0068] In some embodiments of the present invention, a positioning rib is formed on the connector 120. The positioning rib is disposed on the bottom wall of the connector 120 and extends toward the bottom wall of the receiving groove 110a. A positioning protrusion 121 is provided inside the positioning rib, and a positioning groove 111 is formed on the positioning post 110c. The positioning rib and the positioning post 110c can be connected through the positioning protrusion 121 and the positioning groove 111. When the connector 120 moves to the point where the positioning protrusion 121 on the positioning rib engages with the positioning groove 111 on the positioning post 110c, the connector 120 can no longer rotate, which can prevent the limiting member 122 from rotating or loosening, and can also position the installation angle of the connector 120.

[0069] According to some embodiments of the present invention, such as Figure 8 As shown, the positioning groove 111 has guide slopes 111a on both sides in the circumferential direction. Specifically, the guide slopes 111a are adapted to guide the positioning protrusion 121 to engage with the positioning groove 111 after the positioning protrusion 121 rotates into the positioning groove 111. The guide slopes 111a improve the installation efficiency of the connector 120 and facilitate user operation.

[0070] According to some embodiments of the present invention, such as Figures 9-10 As shown, the angle between the lines connecting the mounting channel 110b and the first positioning part to the axis of the cover 110 is α, and the angle between the lines connecting the limiting member 122 and the second positioning part to the axis of the connector 120 is β, where α is greater than or less than β. Specifically, the mounting channel 110b and the limiting member 122 cooperate to restrict the radial movement of the connector 120. Then, the first positioning part and the second positioning part cooperate to restrict the circumferential rotation of the connector 120, thereby restricting the axial movement of the connector 120. To ensure that the first positioning part and the second positioning part do not interfere with the limiting member 122 extending into the mounting channel 110b, it should be ensured that the first positioning part and the second positioning part do not cooperate during the process of the limiting member 122 extending into the mounting channel 110b. Therefore, the mounting channel 110b... The installation channel 110b and the first positioning part are staggered, or the limiting member 122 and the second positioning part are staggered. The angle α between the installation channel 110b and the first positioning part and the axis of the cover 110, and the angle β between the limiting member 122 and the second positioning part and the axis of the connector 120, should satisfy that α is not equal to β, that is, α is greater than or less than β. Only after the limiting member 122 extends into the installation channel 110b and the connector 120 is rotated by a certain angle can the first positioning part and the second positioning part cooperate.

[0071] According to some embodiments of the present invention, such as Figures 11-12As shown, the cover 110 has a plurality of claws 112 extending toward the connector 120. Each claw 112 has a hook 1121 extending radially outward at its free end. The connector 120 is cylindrical and has a locking ring 124 protruding radially inward on its inner circumferential wall. The locking ring 124 engages with the hook 1121 and stops in the axial direction. Specifically, the bottom wall of the cover 110 has a claw 112, which is constructed in multiple ways. The free end of each claw 112 extends outward in the radial direction to form a hook 1121. The connector 120 is cylindrical in shape and has a snap ring 124 on its inner circumferential wall that is suitable for snapping with the hook 1121. The snap ring 124 is constructed to protrude inward in the radial direction. When assembling the end cap assembly 100, the connector 120 only needs to be pressed down until the snap ring 124 snaps with the hook 1121 to complete the connection between the cover 110 and the connector 120, thereby completing the assembly of the end cap assembly 100. The structure is simple and the operation is convenient.

[0072] In the prior art, the outer surfaces of the end cap assembly 100 and the scale inhibition module 300 are mostly cylindrical, making it inconvenient for users to apply force to unscrew the end cap assembly 100. When there is water or detergent on the surface of the end cap assembly 100, the user's hand may slip, resulting in a poor user experience.

[0073] In some embodiments of the present invention, such as Figure 2 As shown, the overall cross-section of the cover 110 is the same as that of the scale inhibition module 300. For example, in some embodiments, the overall cross-section of the cover 110 after it is fitted with the scale inhibition module 300 is circular, and the overall appearance of the cover 110 after it is fitted with the scale inhibition module 300 is cylindrical. In other embodiments, the overall cross-section of the cover 110 after it is fitted with the scale inhibition module 300 is polygonal, and the overall appearance of the cover 110 after it is fitted with the scale inhibition module 300 is a polygonal prism. It can be understood that the overall appearance of the cover 110 after it is fitted with the scale inhibition module 300 is not limited to the cylindrical or polygonal shape mentioned in the above embodiments, but can also be other structures that are easy to remove, place and install.

[0074] According to some embodiments of the present invention, such as Figure 2 , Figure 8As shown, the cover 110 is constructed as a polygonal prism, with a receiving groove 110a formed on its end face. Specifically, to facilitate the user's gripping and opening of the cover 110, the overall appearance of the cover 110 is designed as a polygonal prism structure, with multiple edges on its outer periphery to prevent slippage due to lubrication from water or detergent when the cover 110 is rotated open. More specifically, each surface of the polygonal prism of the cover 110 has a rounded transition with adjacent surfaces to prevent scratches to the user's hands. In some embodiments of the present invention, the cover 110 has a rectangular cross-section with four edges, and the scale inhibition module 300 has the same cross-section as the cover 110. After the cover 110 and the scale inhibition module 300 are fitted together, the overall appearance is a cuboid, which facilitates the overall installation of the scale inhibition module 300 and makes it convenient for the user to pick up and put down the scale inhibition module 300 or to disassemble and assemble the end cap assembly 100, resulting in a good user experience.

[0075] In some embodiments of the present invention, such as Figure 8 As shown, the cover 110 has a rectangular cross-section. A circle extending from the center of the rectangle to the longest side of the rectangle and tangent to the longest side has an outer edge. The surface where the first thread 110d is located is formed on the outer edge of the circle and extends toward the side away from the receiving groove 110a. The first thread 110d is formed on the side of the surface where the first thread 110d is located toward the center of the circle. A gap is formed between the side of the surface where the first thread 110d is located away from the center of the circle and the inner wall of the cover 110. The hollow design of the cover 110 here can reduce the overall weight of the end cap assembly 100.

[0076] like Figure 8As shown, in some embodiments of the present invention, the end cap assembly 100 includes a cap body 110 and a connector 120. The cap body 110 has a cuboid shape, with each surface transitioning to the adjacent surface by an arc. The inner wall of the cap body 110 has a first thread 110d, which is discontinuously distributed. The discontinuities between the first threads 110d form installation channels 110b, and there are four installation channels 110b that are equally spaced. The inside of the cap body 110 has a receiving groove 110a. A positioning post 110c protruding toward the connector 120 is formed at the center of the receiving groove 110a. A positioning groove 111 is formed on the positioning post 110c. A guide slope 111a is formed on the circumferential edge of the positioning groove 111. The positioning groove 111 is positioned opposite one of the installation channels 110b. The connector 120 has two ends. One end of the connector 120 forms a filter mounting position 120a, and the other end of the connector 120 forms three limiting protrusions. The peripheral wall of the connector 120 forms a sealing structure. Each limiting protrusion also has a deformation notch 123 on both sides. Two of the three limiting protrusions are set directly opposite the center of the cross section of the connector 120. The distance from the third limiting protrusion to the two directly opposite limiting protrusions is equal. The minimum included angle between any two adjacent limiting protrusions is a right angle. A positioning rib is provided on the bottom wall of the connector 120. The positioning rib extends toward the bottom wall of the receiving groove 110a. A positioning protrusion 121 is provided inside the positioning rib. The line connecting the positioning protrusion 121 and each limiting protrusion does not pass through the axis of the connector 120.

[0077] When assembling the end cap assembly 100, first insert the limiting protrusion into the receiving groove 110a along the mounting channel 110b and make the positioning rib contact the positioning post 110c. At this time, rotate the connector 120, and the limiting protrusion contacts the bottom wall of the first thread 110d and is offset from the mounting channel 110b until the connector 120 is rotated until the positioning protrusion 121 is about to mate with the positioning groove 111. At this time, the limiting protrusion undergoes a slight deformation so that the positioning protrusion 121 and the positioning groove 111 have an interference fit. After the positioning protrusion 121 mates with the positioning groove 111, the limiting protrusion returns to its original position. When assembling the end cap assembly 100 and the filter screen 200, install the filter screen 200 in the filter screen mounting position 120a. When assembling the end cap assembly 100 and the scale inhibition module 300, the end cap assembly 100 carries the filter screen 200 and extends into the interior of the scale inhibition module 300, and the first thread 110d of the cover body 110 engages with the second thread 300d on the outer periphery of the scale inhibition module 300, thereby completing the installation of the scale inhibition module 300.

[0078] In some embodiments of the present invention, the first thread 110d is longer than the second thread 300d, so that the cover 110 can be rotated into position so that the rectangular cover 110 is aligned and installed with the rectangular scale inhibitor module 300.

[0079] The end cap assembly 100 of the present invention manufactures the connector 120 and the cap 110 as two separate parts. The connector 120 cooperates with the cap 110 and the filter screen 200 respectively to connect the cap 110 and the filter screen 200, which is easy to industrially form and easy to process.

[0080] The scale inhibitor module 300 according to a second aspect embodiment of the present invention is briefly described below.

[0081] like Figure 1 As shown, the scale inhibition module 300 according to the present invention includes the end cap assembly 100 described in any of the above embodiments. Since the scale inhibition module 300 according to the present invention is provided with the end cap assembly 100 of the above embodiments, the scale inhibition module 300 is easy to assemble and connect stably, is not prone to leakage, and is easy to disassemble. The scale inhibition module 300 is less likely to have residual water inside, is cleaner, and provides a better user experience.

[0082] The following is a brief description of a garment processing apparatus according to a third aspect embodiment of the present invention.

[0083] The garment treatment device according to the present invention includes the scale inhibition module 300 described in any of the above embodiments. Since the garment treatment device according to the present invention is provided with the scale inhibition module 300 of the above embodiments, the garment treatment device is easy to clean and assemble, and the garment treatment device has a simple structure, is easy to process, and works more stably.

[0084] In summary, the end cap assembly 100 of the present invention is manufactured as two separate parts. The cap body 110 is connected to the scale inhibition module 300, the filter screen 200 is disposed inside the scale inhibition module 300, and the connector 120 connects the cap body 110 and the filter screen 200. This end cap assembly 100 is easy to industrially form and process. Furthermore, the cuboid shape of the cap body 110 facilitates user handling and opening, improving the user experience. The connector 120 is positioned in three directions by two snap-fit ​​connections, thus fixing the connector 120 to the cap body 110. The connector 120 will not slip off from the cover 110, the connection process is simple and stable, and the connector 120 can be connected to the cover 110 through the existing threaded connection between the cover 110 and the scale inhibitor module 300, without the need for a separate structure for installing the connector 120, which is convenient for processing; there are three limiting members 122 forming a stable triangle, and the two sides of the limiting members 122 have deformation notches 123, which facilitates the deformation of the limiting members 122 when the connector 120 rotates, so that the positioning protrusion 121 engages with the positioning groove 111, thereby fixing the connector 120 to the cover 110, and providing an interference fit positioning groove. The positioning protrusion 121 and the positioning groove 111 prevent loosening of the fit between the limiting member 122 and the first thread 110d, and also position the installation angle of the connecting member 120. The positioning protrusion 121 and the positioning groove 111 have a simple structure and are easy to process. At the same time, the positioning 111 is provided with a guide slope 111a, which makes the installation of the connecting member 120 faster and easier for the user to operate. The axially discontinuous distribution of the first thread 110d is conducive to the molding process of the cover 110, which is easy to process. Residual water can flow out through the installation channel 110b, which is convenient for cleaning and does not easily breed bacteria. The installation channel 110b also facilitates the installation of the limiting member 122. Adjusting the installation angle of the limiting member 122 reduces the resistance to its installation, making it easier to install the connector 120. Providing a positioning post 110c on the cover 110 and a positioning rib on the connector 120 improves the connection stability between the connector 120 and the cover 110, prevents the limiting member 122 from rotating or loosening, and also positions the installation angle of the connector 120. The staggered arrangement of the installation channel 110b and the positioning protrusion 121, or the staggered arrangement of the limiting member 122 and the positioning groove 111, ensures that the positioning protrusion 121 and the positioning groove 111 do not interfere with the limiting member 122 extending into the installation channel 110b.
