Description

Technical Field

[0001] The present invention relates to the field of water purification equipment, and particularly to a water purification equipment and a filter element connector thereof. Background Art

[0002] The quality of the water that users drink plays a crucial role in the users' bodies. In order to have good-quality water for drinking, many users are equipped with a purification device at home, such as a water purifier or a purifier with a filter element. At least one group of filter elements is provided in the purification device. The water purifier has a water inlet and a water outlet. The filter element is arranged between the water inlet and the water outlet and communicates with the water inlet and the water outlet. The water source flowing from the water inlet to the filter element is purified after passing through the filter element. The purified water flow is further guided from the filter element to the outlet of the purification device. Therefore, users using the purification device can drink the water purified by the filter element.

[0003] Whether it is the above-mentioned water purifier or the above-mentioned purifier with a filter element, at least one filter element is provided. The filter element has a predetermined service life, that is to say, it needs to be replaced after being used for a certain period of time. Therefore, when installing the filter element, subsequent disassembly and replacement need to be considered. In the prior art, due to the consideration of the sealing of the waterway structure, a filter element adapter is usually used to fix the filter element. To maintain the sealing of the waterway, generally, the filter element adapter is fixed by means of bolts, screws, etc. On the one hand, this facilitates the disassembly of the filter element. On the other hand, it does not affect the sealing of the waterway. However, this will inevitably increase the number of some accessories for installing the filter element. Once these accessories are lost, it is very difficult to find suitable accessories in a short time, which will affect the installation of the filter element. In addition, disassembling and assembling the filter element using the filter element adapter in the prior art is also very complicated, and the filter element cannot be quickly disassembled and assembled.

[0004] In addition, since the filter element itself has a certain weight, and the filter element is usually installed in an installation cavity of the purification device. Therefore, when replacing the filter element, first, the accessories fixing the filter element need to be disassembled, and then the filter element is taken out from the installation cavity. However, this disassembly method is time-consuming and not conducive to the quick replacement of the filter element. Especially when the operator takes out the filter element from the installation cavity or installs the filter element in the installation cavity, it is not easy to exert force because when the user takes out the filter element from the installation cavity or installs the filter element in the installation cavity, the filter element needs to be held tightly, and at the same time, it is blocked by other parts of the purification device forming the installation cavity.

The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present invention can be applied to other embodiments, variations, improvements, equivalent solutions, and other technical solutions without departing from the spirit and scope of the present invention.

[0052] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationship indicated by terms such as "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present invention.

[0053] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "one" should not be construed as a limitation on the quantity. In addition, in the present invention, "front" and "rear" refer to the sequence of time in some places and the logical sequence in some places. The present invention is not limited in this regard.

[0054] Reference Figures 1 to 7B , a water purification device and its filter element connector according to a preferred embodiment of the present invention will be specifically described below. The water purification device 100 includes a device main body 10, at least one filter element connector 20, and at least one filter element 30. The filter element 30 is rotatably and detachably installed on the device main body 10 through the filter element connector 20.

[0055] The device main body 10 forms a water passage 101 and an installation cavity 102. The filter element 30 is detachably installed in the installation cavity 102 through the filter element connector 20. In a preferred embodiment of the present invention, when the filter element 30 is installed in the installation cavity 102 through the filter element connector 20, the filter element 30 is communicated with the water passage 101 through the filter element connector 20.

[0056] The filter element connector 20 includes a connection body 21, a mounting base 22, and a guiding structure 23. The mounting base 22 is fixed to the device body 10, and the connection body 21 is rotatably connected to the mounting base 22 through the guiding structure 23, so that the connection body 21 can be switched between a disassembly position and an installation position. The filter element 30 is mounted on the connection body 21.

[0057] Specifically, the guiding structure 23 includes two sliding wings 231 and two guiding arc grooves 232 for the two sliding wings to slide respectively. In one embodiment of the present invention, the two guiding arc grooves 232 are provided on the mounting base 22, and the two sliding wings 231 are provided on the connection body 21. Through the two guiding arc grooves 232 and the two sliding wings 231, the connection body can be rotatably mounted on the mounting base between the disassembly position and the installation position.

[0058] In another embodiment of the present invention, the two guiding arc grooves 232 are provided on the connection body 21, and the two sliding wings 231 are provided on the mounting base 22. The present invention is not limited in this regard.

[0059] It is worth mentioning that when the connection body 21 is in the disassembly position, the filter element 30 mounted on the connection body 21 is rotated out of the installation cavity 102 of the device body 10 through the guiding structure 23. At this time, the filter element 30 is in a disassembly state; when the connection body 21 is in the installation position, the filter element 30 mounted on the connection body 21 is rotated into the installation cavity 102 through the guiding structure 23 and is fixed in the installation cavity 102. At this time, the filter element 30 is in a working state.

[0060] That is to say, when the connection body 21 with the filter element 30 mounted thereon is mounted on the mounting base 22 of the device body 10 and the filter element 30 is fixed in the installation cavity 102 of the device body 10 and cannot be disassembled, the filter element 30 is in the working state. When the connection body 21 with the filter element 30 mounted thereon is mounted on the mounting base 22 and the filter element 30 can be disassembled from the connection body 21, the filter element 30 is in the disassembly state.

[0061] More notably, the mounting base 22 can be implemented as a part of the device main body 10, that is to say, the mounting base 22 can be integrally provided on the device main body 10. The mounting base 22 can also be implemented to be detachably mounted on the device main body 10. In at least one embodiment of the present invention below, only the case where the mounting base 22 is implemented to be detachably mounted on the device main body 10 is taken as an example for illustration, but those skilled in the art can understand that this is not a limitation to the present invention.

[0062] Those skilled in the art can understand that in the present invention, when the connecting body 21 is rotated to the dismounting position, the filter element 30 is rotated out of the mounting cavity 102 of the water purification device 100. Since there are no obstacles around the filter element 30 that is rotated out of the water purification device 100, therefore, the filter element 30 in the dismounting state is relatively easy to be dismounted for the operator.

[0063] Also notably, in the present invention, since the connecting body 21 is rotatably mounted on the mounting base 22, therefore, when the filter element 30 is switched from the working state to the dismounting state, the connecting body 21 can serve as a force arm for the operator's rotational operation, so that the user can facilitate the rotation of the connecting body 21 to rotate the filter element 30 out of the mounting cavity 102. In addition, since the filter element 30 connected to the connecting body 21 has a certain height, after the filter element 30 is mounted on the connecting body 21, the filter element 30 can extend the length of the force arm when the connecting body 21 rotates relative to the mounting base 22, thus reducing the force that the operator needs to apply to the connecting body 21 relative to the mounting base 22.

[0064] Specifically, the connecting body 21 includes a connecting body 211, wherein the connecting body 211 is rotatably connected to the mounting base 22. Specifically, the filter element connector 20 further includes a rotational connection structure 24, wherein by means of the rotational connection structure 24, the connecting body 21 is rotatably connected to the mounting base 22, so that the filter element 30 mounted on the connecting body 21 can be switched between the working state and the dismounting state.

[0065] The rotational connection structure 24 includes a pair of rotating shafts 241 and a pair of shaft holes 242, wherein the pair of rotating shafts 241 are provided on the connecting body 211, and the pair of shaft holes 242 are provided on the mounting base 22. Therefore, through the cooperation between the rotating shafts 241 and the shaft holes 242 of the rotational connection structure 24, the connecting body 21 can be rotatably connected to the mounting base 22.

[0066] It is worth mentioning that each of the rotating shafts 241 can be implemented to be detachably mounted on the connecting body 21, and a pair of the rotating shafts 241 can also be implemented to be integrally extended from both sides of the connecting body 21 respectively. Those skilled in the art can understand that the present invention is not limited in this regard. Preferably, a pair of the rotating shafts 241 are implemented to be integrally extended from both sides of the connecting body 21 respectively.

[0067] A pair of the shaft holes 242 of the rotary connection structure 24 are disposed on the mounting base 22. Therefore, through the cooperation between the rotating shaft 241 and the shaft hole 242 of the rotary connection structure 24, the connection body 211 of the connecting body 21 is rotatably connected to the mounting base 22.

[0068] Those skilled in the art can understand that a pair of the rotating shafts 241 can also be disposed on the mounting base 22, and a pair of the shaft holes 242 are correspondingly disposed on the connecting body 21. The present invention is not limited in this regard. To enable those skilled in the art to understand the present invention, in at least one embodiment of the present invention, only a pair of the rotating shafts 241 are disposed on the connecting body 21 and a pair of the shaft holes 242 are disposed on the mounting base 22 are described.

[0069] Referring to FIG. 3, Figure 5A , Figure 5B and Figure 6A , in an embodiment of the present invention, the connecting body 21 has a liquid passage 2101, a filtrate inlet 2102 and a filtrate outlet 2103. When the connecting body 21 is mounted on the mounting base 22 and the mounting base 22 is fixed to the mounting cavity 201 of the water purification device 100, the liquid passage 2101 of the connecting body 21 always remains in communication with the water passage 101 on the water purification device 100. In addition, when the filter element 30 is mounted on the connecting body 21, the filter element 30 is in communication with the filtrate inlet 2102 and the filtrate outlet 2103 of the connecting body 21, so that the liquid in the water passage 101 passes through the filter element 30 from the filtrate inlet 2102 of the connecting body 21 for purification treatment and is then led out from the filtrate outlet 2103.

[0070] The liquid passage 2101 has at least one liquid inlet 21011 and at least one liquid outlet 21012, wherein the filtrate inlet 2102 and the filtrate outlet 2103 are respectively communicated with the liquid passage 2101 and are between the liquid inlet 21011 and the liquid outlet 21012. The liquid inlet 21011 is communicated with the filtrate inlet 2102. The liquid outlet 21012 is communicated with the filtrate outlet 2103. When the filter element 30 is installed on the connection body 21, the filter element 30 is communicated with the filtrate inlet 2102 and the filtrate outlet 2103. Therefore, when liquid flows in from the liquid inlet 21011 of the liquid passage 2101, it flows from the filtrate inlet 2102 to the filter element 30 installed on the connection body 21, and after being purified by the filter element 30, it flows from the filtrate outlet 2103 to the liquid outlet 21012.

[0071] Referring to FIG. 3, Figure 5A , Figure 5B and Figure 6B , in another embodiment of the present invention, the connection body 21 has a liquid passage 2101a, a filtrate inlet 2102a, a filtrate outlet 2103a and a waste water outlet 2104a. The connection body 21a is connected to the device body 10a, and when the device body 10 is fixed in the installation cavity of the water purification device 100a, the liquid passage 2101a of the connection body 21 always remains in communication with the water passage 101 on the water purification device 100a. In addition, when the filter element 30 is installed on the connection body 21, the filter element 30 is communicated with the filtrate inlet 2102a and the filtrate outlet 2103a of the connection body 21.

[0072] The liquid passage 2101a has at least one liquid inlet 21011a, at least one liquid outlet 21012a and a waste water outlet 21013a, wherein the filtrate inlet 2102a and the filtrate outlet 2103a are communicated with the liquid passage 2101a and are between the liquid inlet 21011a and the liquid outlet 21012a. The liquid inlet 21011a is communicated with the filtrate inlet 2102a. The liquid outlet 21012a is communicated with the filtrate outlet 2103a. The waste water outlet 21013a is communicated with the waste water outlet 2104a. When the filter element 30 is installed on the connection body 21, the filter element 30 is communicated with the filtrate inlet 2102a, the filtrate outlet 2103a and the waste water outlet 2104a is conducted. Therefore, when the liquid flows in from the liquid inlet 21011a of the liquid passage 2101a, it flows from the filtrate inlet 2102a to the filter element 30 installed on the connection body 21, and after the liquid is purified by the filter element 30, it can flow from the filtrate outlet 2103a to the liquid outlet 21012a.

[0073] Further, the connection body 211 of the connection body 21 has two end faces 2110, specifically a first end face 2110a and a second end face 2110b. The connection body 21 further includes two extension arms, specifically a first extension arm and a second extension arm. The connection body 21 integrally extends outward from the first end face 2110a to form the first extension arm. The connection body 21 integrally extends outward from the second end face 2110b to form the second extension arm. Those skilled in the art can understand that in another embodiment of the present invention, the connection body 21 integrally extends outward from the second end face 2110b to form the first extension arm, and the connection body 21 integrally extends outward from the first end face 2110a to form the second extension arm. The present invention is not limited in this regard. To enable those skilled in the art to understand the present invention, in the following examples of the present invention, only the connection body 211 of the connection body 21 integrally extending outward from the first end face 2110a to form the first extension arm and integrally extending outward from the second end face 2110b to form the second extension arm is taken as an example for illustration.

[0074] It is worth mentioning that in the present invention, the first extension arm and the second extension arm of the connection body 21 are simultaneously a pair of the rotating shafts 241 of the rotating connection structure 24, as Figure 4A and Figure 4B shown.

[0075] It is also worth mentioning that the liquid channel 2101 is arranged to extend from one end of one extension arm to the other end of the other extension arm. For example, the liquid inlet 21011 and the liquid outlet 21012 of the liquid channel 2101 are respectively arranged at one end of the first extension arm and one end of the second extension arm of the connection body 211.

[0076] More notably, in the present invention, the shaft hole 242 of the rotational connection structure 24 is coaxially arranged on the mounting base 22 to be adapted to the first extension arm and the second extension arm of the connection body 21, so that the connection body 211 can rotate relative to the mounting base 22 through the first extension arm and the second extension arm via the rotating shaft 241 and the shaft hole 242.

[0077] Furthermore, the mounting base 22 includes two seat bodies 221, and each seat body 221 is fixed to the device main body 10 of the water purification device 100 and is located in the mounting cavity 102. In at least one embodiment of the present invention, each seat body 221 is detachably arranged on the device main body 10.

[0078] Each seat body 221 respectively has an inner side surface 22101 close to the connection body 21 and an outer side surface 22102 opposite to the inner side surface 22101.

[0079] The shaft hole 242 of the rotational connection structure 24 is arranged on the inner side surface 22101 of each seat body 221, so that the connection body 21 can be rotatably connected to the mounting holes of the two seat bodies 221 of the device main body 10 through the shaft hole 242 arranged on the connection body 21 and adapted to the rotating shaft 241. Preferably, each shaft hole 242 extends from the inner side surface 22101 of the seat body 221 to the outer side surface 22102, so that the two extension arms can respectively pass through the shaft hole 242, facilitating the liquid inlet arranged on the first extension arm and the liquid outlet arranged on the second extension arm to be respectively communicated with the water path 101 through the mounting holes.

[0080] It is worth mentioning that when the connection body 21 is installed on the device main body 10, the first end surface 2110a of the connection body 21 is opposite to the inner side surface 22101 of one seat body 221 fixed to the device main body 10, and the second end surface 2110a of the connection body 21 is opposite to the inner side surface 22101 of the other seat body 221 fixed to the device main body 10.

[0081] Furthermore, the filter element connector 20 includes a guiding structure 25, wherein the guiding structure 25 includes at least a pair of balls 251 and at least a pair of arc-shaped guiding grooves 252. The balls 251 are disposed on the first end face 2110a and the second end face 2110b of the connection body 21. The arc-shaped guiding grooves 252 are respectively disposed on the inner side faces 22101 of each seat body 221 of the device body 10. After the connection body 21 is connected to the device body 10, the filter element 30 mounted on the connection body 21 can be switched between the working state and the disassembly state by means of the rotational connection structure 24, that is to say, by means of the rotational connection structure 24, the connection body 21 can be switched between the installation position and the disassembly position.

[0082] In an embodiment of the present invention, the balls 251 are symmetrically disposed on the first end face 2110a and the second end face 2110b of the connection body 21. The arc-shaped guiding grooves 252 are symmetrically disposed on the inner side faces 22101 of each seat body 221. Those skilled in the art can understand that, in another embodiment of the present invention, the arc-shaped guiding grooves 252 are symmetrically disposed on the first end face 2110a and the second end face 2110b of the connection body 21, and the balls 251 are disposed on the inner side faces 22101 of each seat body 221 of the device body 10. To enable those skilled in the art to understand the present invention, in the following embodiments of the present invention, only three pairs of balls and one pair of arc-shaped guiding grooves are respectively implemented for the balls 2511 and the arc-shaped guiding grooves 252, and the balls 251 are disposed on the first end face 2110a and the second end face 2110b as an example for illustration. Those skilled in the art can understand that the present invention is not limited in this regard.

[0083] It is worth mentioning that when the extending direction of the arc-shaped guiding groove 252 is adapted to the way the filter element 30 rotates relative to the installation base 22. Preferably, positioning grooves 2520 are respectively disposed at both ends of each arc-shaped guiding groove 252, wherein the balls 251 are telescopically disposed on the connection body 21 in a direction perpendicular to the first end face 2110a and the second end face 2110b, so that after the connection body 21 is mounted on the installation base 22, the guiding structure 25 can not only guide the filter element 30 to be switched between the working state and the disassembly state. When the filter element 30 is rotated to the working state or the disassembly state, by means of the positioning grooves 2520, the connection body 21 on which the filter element 30 is mounted is fixed relative to the installation base 22.

[0084] Specifically, when the connecting body 21 rotates relative to the mounting base 22, the ball 251 provided on the connecting body 21 is guided by the arc-shaped guide groove 252 provided on the inner side surface 22102 of the mounting base 22 and rotates. When the ball 251 slides in the arc-shaped guide groove 252, the ball 251 is pressed into the connecting body 21 for mounting the ball 251. When the ball 251 slides to the positioning groove 2520, the ball 251 is released and held in the positioning groove 2520. In this way, while the connecting body 21 is guided by the guiding structure 25 and rotates, it can be positioned.

[0085] Further, the connecting body 211 is provided with a mounting portion 212 for detachably mounting the filter element 30. In an embodiment of the present invention, the filtrate inlet 2102 and the filtrate outlet 2103 are respectively provided on the mounting portion 212, and when the filter element 30 is fixed to the mounting portion 212 of the connecting body 211, the filter element 30 is docked with the filtrate inlet 2102 and the filtrate outlet 2103 at the connecting body 211.

[0086] In another embodiment of the present invention, the filtrate inlet 2102a, the filtrate outlet 2103a, and the wastewater outlet 2104a are provided on the mounting portion 212, and when the filter element 30 is installed and fixed to the mounting portion 212 of the connecting body 211, the filter element 30 is docked with the filtrate inlet 2102a, the filtrate outlet 2103a, and the wastewater outlet 2104a at the connecting body 211.

[0087] Reference Figures 2 to 3C , specifically, in an embodiment of the present invention, the mounting portion 212 is implemented as a groove with a threaded structure on the inner wall to cooperate with the filter element 30 with a threaded structure to be installed and fixed to the mounting portion 212 by means of threaded connection. The filtrate inlet 2102 and the filtrate outlet 2103 are respectively provided on the bottom wall of the groove. Further, after the filter element 30 is installed and fixed to the mounting portion 212, the filter element 30 is docked with the filtrate inlet 2102 and the filtrate outlet 2103 and is sealed and conducted.

[0088] It can be understood that when the filter element 30 installed in the installation part 212 needs to be replaced, first, the connection body 21 installed with the filter element 30 can be rotated out of the installation cavity of the water purification device 100, so that the connection body 21 rotates from the working state to the disassembly state. It is worth mentioning that the filter element 30 itself serves as a lever arm, enabling the operator to rotate the connection body 21 installed with the filter element 30 out of the installation cavity of the water purification device 100 with only a small force.

[0089] It is worth mentioning that in the present invention, during the rotation of the connection body 21 relative to the installation base 22, the guiding structure 25 can simultaneously provide guidance. Especially when the balls 251 are arranged on the two end faces 2110 of the connection body 21, and the arc-shaped guide grooves 252 are arranged on the inner side faces 22101 of each seat body 221, during the rotation of the connection body 21 relative to the installation base 22, the balls 251 and the arc-shaped guide grooves 252 relatively slide in a rolling friction manner, correspondingly reducing the frictional force between the connection body 21 and the installation base 22, and further enabling the operator to be more labor-saving when converting the connection body 21 installed with the filter element 30 between the working state and the disassembly state relative to the installation base 22.

[0090] When the connection body 21 installed with the filter element 30 is rotated relative to the installation base 22 to the disassembly state, the user can disassemble the filter element 30 from the installation part 212 of the connection body 211, replace it, and then use the filter element 30 as a lever arm to convert the connection body 21 installed with the replaced filter element 30 from the disassembly state to the working state relative to the device main body 10 to complete the replacement of the filter element 30.

[0091] Those skilled in the art can understand that with the filter element connector 20 of the present invention, the replacement of the filter element 30 becomes more convenient.

[0092] Reference Figures 4A to 5C , in another embodiment of the present invention, the installation part 212 of the connection body 211 is implemented as a plug-in slot for plugging the filter element 30. The filtrate inlet 2102 and the filtrate outlet 2103 are respectively arranged on the bottom wall of the plug-in slot, so that after the filter element 30 is plugged into the plug-in slot, the filtrate inlet 2102 and the filtrate outlet 2103 are communicated with the filter element 30.

[0093] Furthermore, in the present embodiment, the connection body 21 includes a filter element adapter 213, wherein the filter element adapter 213 is detachably inserted into the installation portion 212 of the connection body 211, and the filter element adapter 213 can be docked with the filter element 30.

[0094] It is worth mentioning that when the filter element 30 installed on the connection body 21 together with the connection body 21 is switched from the working state to the disassembly state relative to the installation base 22, the filter element 30 can be directly removed without any other extra steps. In addition, when the filter element 30 is switched from the disassembly state to the working state, the filter element 30 is simultaneously fixed and sealedly docked with the filtrate inlet 2102 and the filtrate outlet 2103 on the connection body 21.

[0095] It is worth mentioning that in the present embodiment, when the connection body 21 is switched between the working state and the disassembly state relative to the installation base 22, the filter element 30 installed on the connection body 21 can also serve as a lever arm for the operator, thereby making it easier for the operator to replace the filter element 30. More notably, since the filter element 30 installed on the connection body 21 can be directly removed when switched from the working state to the disassembly state without any other extra steps, the quick replacement of the filter element 30 can be achieved.

[0096] In the present embodiment, the filter element adapter 213 is detachably inserted into the installation portion 212 of the connection body 211. Two sliding wings 231 are respectively arranged on both sides of the adapter 213. Specifically, one side of the adapter 213 integrally extends outward to form one sliding wing 231. The symmetrically opposite side of the adapter 213 integrally extends outward to form the other sliding wing 231. In another embodiment of the present invention, guiding arc grooves 232 are respectively arranged on both sides of the adapter 213 instead of the sliding wings 231. Preferably, to enable those skilled in the art to understand the present invention, in the following embodiments of the present invention, only the example where the sliding wings 231 are arranged on both sides of the filter element adapter 213 is used for illustration.

[0097] The adapter 213 of the filter element adapter 213 has a docking end 2131 and a diversion end 2132. The docking end 2131 of the adapter 213 is further provided with a docking inlet 213101 and a docking outlet 213102. When the filter element adapter 213 is installed on the connection body 211, the docking inlet 213101 and the docking outlet 213102 are respectively docked with the filtrate inlet 2102 and the filtrate outlet 2103 of the connection body 21.

[0098] In addition, the diversion end 2132 of the adapter body 2131 is further provided with a diversion inlet 213201 and a diversion outlet 213202. The diversion inlet 213201 is communicated with the docking inlet 213101, and the diversion outlet 213202 is communicated with the docking outlet 213102. Therefore, when the filter element 30 is fixed to the filter element adapter 213, the filter element 30 is simultaneously communicated with the diversion inlet 213201 and the diversion outlet 213202 of the filter element adapter 213. That is to say, when the liquid flows in from the liquid inlet 21011 of the liquid passage 2101, the liquid first enters the filtrate inlet 2102, and then enters the filter element 30 through the docking inlet 213101 and the diversion inlet 213201 on the filter element adapter 213.

[0099] After the liquid is filtered by the filter element 30, the formed potable water flows out of the filter element 30, passes through the diversion outlet 213202 of the diversion end 2132 of the adapter body 2131 and the docking outlet 213102 of the docking end 2131, and then flows from the filtrate outlet 2103 to the liquid outlet 21012 of the liquid passage 2101.

[0100] In another embodiment of the present invention, the docking end 2131 further has a docking waste water port 213103a. When the filter element adapter 213 is installed on the installation part 212 and the connection body 21 is rotated to the installation position, the docking waste water port 213103a is hermetically docked with the waste water outlet 2104a, so that the docking waste water port 213103a is hermetically communicated with the waste water outlet 2104a.

[0101] Each of the guiding arc grooves 232 is respectively adapted to the sliding wing 231, so that when the filter element adapter 213 is installed on the installation part 212 of the connection body 211 and the connection body 21 is switched between the working state and the disassembly state relative to the installation base 22, the two sliding wings 231 of the filter element adapter 213 can be guided by the guiding arc grooves 232 and slide along the guiding arc grooves 232. Since each of the sliding wings 231 of the filter element adapter 213 is correspondingly limited in each guiding arc groove 232 of each installation base 22, the filter element adapter 213 is fixed relative to the connection body 21.

[0102] Preferably, each of the guiding arc grooves 232 is provided on the inner side surface 22101 of each seat body 221. Each of the guiding arc grooves 232 has a first arc end 2321 and a second arc end 2322. When the filter element 30 installed on the sliding wing 231 is rotated to the disassembly state, the sliding wing 231 is positioned at the first arc end 2321 of the guiding arc groove 232. When the filter element 30 installed on the sliding wing 231 is rotated to the working state, the sliding wing 231 is positioned at the second arc end 2322 of the guiding arc groove 232. It can be understood that a sliding wing 231 instead of the guiding arc groove 232 can be provided on the inner side surface 22101 of each seat body 221. The present invention is not limited in this regard. To enable those skilled in the art to understand the present invention, in at least one embodiment of the present invention, only the example that each guiding arc groove 232 is provided on the inner side surface 22101 of each seat body 221 is described.

[0103] A notch 222 communicating with the first arc end 2321 of the guiding arc groove 232 is further symmetrically provided on the inner side surface 22101 of each of the two seat bodies 221 of the device body 10. When the filter element 30 with the filter element adapter 213 installed thereon is switched from the working state to the disassembly state, the two sliding wings 231 on the filter element adapter 213 are rotated to the first arc end 2321 of the guiding arc groove 232 provided with the notch 222. At this time, the filter element adapter 213 can be directly disassembled from the installation part 212 of the connection body 211.

[0104] Preferably, in the present embodiment, each of the sliding wings 231 of the filter element adapter 213 is implemented as an arc shape adapted to the guiding arc groove 232. More preferably, the radius of curvature of the guiding arc groove 232 gradually increases from the first arc end 2321 where the guiding arc groove 232 communicates with the notch 222 to the second arc end 2322 of the guiding arc groove 232. Therefore, when the filter element 30 mounted on the filter element adapter 213 is switched from the disassembly state to the working state, the two sliding wings 231 of the filter element adapter 213 can not only be mounted on the mounting base 22 through the guiding arc groove 232, but also each sliding wing 231 is subjected to the pressure exerted by the guiding structure, so that while the filter element adapter 213 can be maintained in the working state, the docking inlet 213101 and the docking outlet 213102 at the docking end 2131 of the filter element adapter 213 are hermetically docked with the filtrate inlet 2102 and the filtrate outlet 2103 of the connecting body 21, thereby also avoiding the phenomenon of liquid leakage due to the lack of sealing between the filter element adapter 213 and the connecting body 21 after the filter element adapter 213 is fixed to the connecting body 21. From the above description, it can be understood that the filter element 30 can not only be detachably mounted on the device main body 10 by means of the filter element connector 20, but also can simultaneously hermetically dock the filter element 30 with the water channel 101 formed by the device main body 10. In addition, the filter element 30 can also be switched between the working state and the disassembly state through the filter element connector 20 to facilitate the replacement of the filter element 30.

[0105] In addition, when the filter element adapter 213 is rotated and the sliding wing 231 is rotated from the second arc end 2322 to the first arc end 2321, the pressure on the sliding wing 231 by the guiding arc groove 232 gradually decreases. Furthermore, when the sliding wing 231 slides to the first arc end 2321, the sliding wing 231 is released from the guiding arc groove 232 to facilitate the disassembly of the filter element adapter 213.

[0106] More preferably, a blocking member 223 is provided at the second arc end 2322 of the second guiding arc groove 232 of each seat body 221, so that after the sliding wing 231 of the filter element adapter 213 slides from the first arc end 2321 of the guiding arc groove 232 to the second arc end 22102, each sliding wing 231 can be blocked by the blocking member 223, and correspondingly, the filter element adapter 213 is fixed to the mounting base 22.

[0107] It is worth mentioning that in another embodiment of the present invention, the sliding wing 231 is implemented as the arc groove, and the guiding structure 2111 is implemented as the guide wing. Accordingly, the notch 222 and the blocking member 223 are respectively arranged at the first arc end 2321 and the second arc end 2322 of the sliding wing 231.

[0108] It can be understood by those skilled in the art that, in this embodiment, when the filter element 30 needs to be replaced, it is only necessary to convert the filter element 30 installed on the filter element connector 20 from the working state to the disassembly state, and during the operation, the filter element 30 is directly used as a lever arm for rotation, thereby saving more effort. Subsequently, the filter element 30 can be directly pulled out from the filter element connector 20. Subsequently, the replaced filter element 30 can be directly installed on the filter element connector 20, and then the filter element 30 can be rotated relative to the mounting base 22 with the filter element 30 as the fulcrum, so that the replaced filter element 30 can be converted to the working state.

[0109] It is worth mentioning that, in one embodiment of the present invention, the filter element adapter 213 is detachably connected to the filter element 30. In another embodiment of the present invention, the filter element adapter 213 is implemented as a part of the filter element 30. That is, in the present invention, the filter element 30 includes a filter element body 31 and the filter element adapter 213 disposed on the filter element body 31.

[0110] It is worth mentioning that when the filter element adapter 213 is implemented as a part of the filter element 30, the filter element 30 is fixed to the connecting body 21 through the plugging with the mounting portion 212 of the connecting body 211 and the cooperation between the sliding wing 231 of the filter element adapter 213 and the guiding arc groove 232 on the inner side surface 22101 of each seat body 221. Therefore, when replacing the filter element 30, it is not necessary to use other accessories to fix the filter element 30, thereby facilitating the rapid replacement of the filter element 30.

[0111] The embodiments used to explain the functional and structural principles of the present invention have been fully described and illustrated, and the present invention is not limited to changes based on the principles of these embodiments. Therefore, the present invention includes all modifications within the scope and spirit of the appended claims.
