[0038] The utility model provides a filter 1.

[0039] In the embodiment of the present utility model, Figures 1 to 7 As shown, the filter 1 includes a filter element assembly 10 and a connecting seat 50; a connecting groove 131 is provided at one end of the filter element assembly 10, and a mounting groove 1311 is recessed on the groove wall of the connecting groove 131 in a direction away from the center; a movable member 14 and a first elastic member 15 are also provided in the mounting groove 1311, one end of the first elastic member 15 is connected to the groove bottom of the mounting groove 1311, and the other end elastically abuts against the movable member 14, the movable member 14 is movably inserted into the mounting groove 1311, and a side surface of the movable member 14 facing one end of the filter element assembly 10 is an inclined surface, and the inclined surface is inclined from one end close to the first elastic member 15 to the other end; the connecting seat 50 includes a seat body 51 and a clamping assembly Part 53, the fixing assembly 53 includes a first conical fastener 532, a second conical fastener 533 and a second elastic member 534, one end of the first conical fastener 532 is connected to the surface of the seat body 51, the second conical fastener 533 is movably mounted on a side of the first conical fastener 532 close to the seat body 51, the conical extension directions of the first conical fastener 532 and the second conical fastener 533 are arranged in opposite directions, one end of the second elastic member 534 is connected to the surface of the seat body 51, and the other end is elastically supported on an end face of the filter element assembly 10; the connecting seat 50 and the filter element assembly 10 have a first driving seat body 51 locked state, and a second driving seat body 51 separated state.

[0040] The filter 1 includes a filter element assembly 10 and a connecting seat 50. A connecting groove 131 is provided at one end of the filter element assembly 10. A mounting groove 1311 is recessed in the groove wall of the connecting groove 131 in a direction away from the center. A movable member 14 and a first elastic member 15 are arranged in the mounting groove 1311. One end of the first elastic member 15 is connected to the groove bottom of the mounting groove 1311, and the other end elastically abuts against the movable member 14. When the first elastic member 15 is in a relaxed state, the movable member 14 extends out of the notch of the mounting groove 1311. When a certain pressure is applied to the movable member 14, the movable member 14 partially extends into the mounting groove 1311, and the first elastic member 15 is compressed. The surface of the movable part 14 facing one end of the filter element assembly 10 is an inclined surface, and the inclined surface is inclined in the direction from one end close to the first elastic part 15 to the other end. The connecting seat 50 includes a seat body 51 and a clamping assembly 53, and the clamping assembly 53 includes a first conical fastener 532 and a second conical fastener 533. When the first elastic part 15 is in a relaxed state, the initial position of the movable part 14 is set at a position close to the central axis direction of the first conical fastener 532 and the second conical fastener 533, so when the first conical fastener 532 or the second conical fastener 533 abuts against the movable part 14, it has a pressing and compressing effect on the first elastic part 15. The first elastic part 15 can be a spring, a spring sheet, an elastic colloid, etc., which is not limited here.

[0041] Furthermore, the fastening assembly 53 further includes a second elastic member 534, one end of which is connected to the surface of the seat body 51, and the other end of which is elastically pressed against an end surface of the filter element assembly 10. When the connecting seat 50 is not connected to the filter element assembly 10, the second elastic member 534 is in a relaxed state, and when the connecting seat 50 is connected to the filter element assembly 10, that is, the first conical fastener 532 is inserted into the receiving groove, the second elastic member 534 is compressed. The second elastic member 534 can be a spring, a spring sheet, an elastic colloid, etc., which is not limited here.

[0042] Furthermore, the side surfaces of the first conical fastener 532 and the second conical fastener 533 are both conical, that is, the diameter is gradually reduced from one end to the other end. It can be understood that the inclination of the conical surface of the first conical fastener 532 and the second conical fastener 533 can be the same, or the inclination of the conical surface of the first conical fastener 532 is greater than the inclination of the second conical fastener 533, so as to facilitate the smoothness of the movable part 14 when sliding along the outer surface of the first conical fastener 532. In this embodiment, the conical extension directions of the first conical fastener 532 and the second conical fastener 533 are set in opposite directions, that is, the cone angle of the first conical fastener 532 is set away from the seat body 51, and the cone angle of the second conical fastener 533 is set towards the seat body 51, and the opposite end surfaces of the first conical fastener and the second conical fastener 533 are both planes.

[0043] When the first conical fastener 532 is moved in the plugging direction, the movable part 14 can be opened by cooperating with the inclined surface of the movable part 14 along the installation and insertion direction of the connecting seat 50 and the filter element assembly 10; since the second conical fastener 533 is in a position with a certain interval with the first conical fastener 532 when in the initial position, a fastening clamping groove is formed at the interval between the two, and the movable part 14 is opened and slides along the first conical fastener 532, and can slide into the clamping groove, so that the movable part 14 is clamped between the first conical fastener 532 and the second conical fastener 533, and due to the rebound of the first elastic part 15, the position of the movable part 14 in the clamping groove can be maintained, so that the movable part 14 is located in the clamping groove, which has a limiting effect on the first conical fastener 532 and the second conical fastener 533 in the plugging direction, and then a clamping position is formed between the filter element assembly 10 and the connecting seat 50, and the two cannot move relative to each other, thereby realizing a fast connection between the two.

[0044] Furthermore, the movable member 14 is located between the first conical fastener 532 and the second conical fastener 533. When the seat body 51 is driven to move the second conical fastener 533 in the plug-in direction, the end face of the second conical fastener 533 can exert a force on the inclined surface in the plug-in direction and in the direction of the mounting groove 1311, and also has an opening effect on the movable member 14. When the opening distance of the movable member 14 reaches the diameter of the end face of the second conical fastener 533, the second conical fastener 533 is continued to be driven to move in the plug-in direction. The conical side surfaces are in contact, and the conical side surfaces press against the movable part 14; however, as the movable part 14 moves along the side surface, as the distance between the side surface and the mounting groove 1311 increases, the force acting on the movable part 14 is reduced, and through the rebound of the first elastic part 15, the movable part 14 can maintain the outer surface of the second conical fastener 533 for pressing, and has a force on the second conical fastener 533 in the direction of plugging, and then the movable part 14 can push the second conical fastener 533 in the reverse direction to move toward the first conical fastener 532, so that the two are in contact. When the second conical fastener 533 abuts against the first conical fastener 532, the driving of the connecting seat 50 stops, the second elastic member 534 rebounds, and the first conical fastener 532 and the second conical fastener 533 both move in the opposite direction of the plug-in direction, and then the movable member 14 slides in the order from the outer surface of the second conical fastener 533 to the outer surface of the first conical fastener 532, and finally escapes from the end of the first conical fastener 532, realizing the unlocking and separation of the filter element assembly 10 and the connecting seat 50. In addition, after the movable member 14 escapes, the first elastic member 15 rebounds to restore the movable member 14 to its initial position, and the second conical fastener 533 is separated from the first conical fastener 532 due to the absence of the force of the movable member 14, and returns to its initial position, so that the next locking can be performed.

[0045] In this embodiment, the connection seat 50 and the filter cover 13 have a locked state and a separated state, and the conversion steps between the two are as follows:

[0046] The seat body 51 is driven for the first time, and the first conical fastener 532 is inserted into the connecting groove 131, and its conical surface presses the movable member 14 to open and compress the first elastic member 15 and the second elastic member 534, so that the movable member 14 is engaged between the first conical fastener 532 and the second conical fastener 533, and the connecting seat 50 and the filter element assembly 10 are converted into a locked state;

[0047] The seat body 51 is driven for the second time, and the first conical fastener 532 and the second conical fastener 533 continue to be inserted into the connecting groove 131. The end surface of the second conical fastener 533 facing the moving direction presses against the moving part 14 along the inclined surface thereof, so that the moving part 14 opens, compresses the first elastic part 15, and moves into the mounting groove 1311. As the moving part 14 is continuously inserted, it opens to the size of the end plane of the second conical fastener 533, and then slides along the conical outer surface of the second conical fastener 533. The moving part 14 is subjected to the rebound force of the first elastic part 15 and extends out of the mounting groove 1311, and the second The conical surface of the conical fastener 533 has a resisting force toward the first conical fastener 532, so that the second conical fastener 533 moves toward the first conical fastener 532 and connects with the first conical fastener 532; the driving of the seat body 51 stops, the second elastic member 534 recovers and drives the seat body 51 to move in the opposite direction, and the movable member 14 slides along the outer surface of the second conical fastener 533 and the first conical fastener 532 after docking, and disengages from the fixing assembly 53 after passing the conical surface of the first conical fastener 532, thereby realizing the separation of the movable member 14 from the fixing assembly 53, and the connecting seat 50 and the filter element cover 13 are converted into a separated state.

[0048] The technical solution of the utility model can realize the connection and separation of the filter element cover 13 and the connecting seat 50 by the first driving limit clamping and the second driving pressing separation of the filter element assembly 10 and the fixing assembly 53 on the connecting seat 50, and the filter element cover 13 and the connecting seat 50 can be connected and separated by continuously driving the seat body 51. The operation is simple and the connection efficiency is high. In addition, the structure of the first conical fastener 532 and the second conical fastener 533 is simple, and the mold structure thereof is simple, and the manufacturing cost is low.

[0049] In one embodiment of the present invention, Figure 6 As shown, the maximum diameter of the second tapered fastener 533 is greater than the maximum diameter of the first tapered fastener 532 .

[0050] In this embodiment, the maximum diameter of the second conical fastener 533 is greater than the maximum diameter of the first conical fastener 532. When the second conical fastener 533 abuts against the first conical fastener 532, the driving connection seat 50 stops, and the second elastic member 534 rebounds, that is, when the movable member 14 moves along the outer surface of the second conical fastener 533 and the connection between the two to the outer surface of the first conical fastener 532, the diameter of the connecting end surface of the second conical fastener 533 is greater than the diameter of the connecting end surface of the first conical fastener 532. The sliding of the movable member 14 can directly move from the outer surface of the second conical fastener 533 to the outer surface of the first conical fastener 532, avoiding the situation where the movable member 14 slides to the connection between the two, ensuring the effect of the movable member 14 escaping from the outer surface of the second conical fastener 533 to the fixing assembly 53, and improving the stability of the movable member 14 in converting from the locked state to the separated state.

[0051] In one embodiment of the present invention, Figures 5 to 7 As shown, the connecting seat 50 also includes a connecting column 531, and the connecting column 531 includes a limiting portion 5311 and a connecting portion 5313 connected to each other. The diameter of the limiting portion 5311 is larger than the diameter of the connecting portion 5313. The limiting portion 5311 is connected to the surface of the seat body 51, and one end of the connecting portion 5313 away from the limiting portion 5311 is connected to the first conical fastener 532. The second conical fastener 533 is movably mounted on the connecting portion 5313, and the end face of the second conical fastener 533 facing away from the first conical fastener 532 is abutted against the limiting portion 5311.

[0052] In this embodiment, the connection seat 50 further includes a connection column 531, and the connection column 531 includes a limit portion 5311 and a connection portion 5313 connected to each other, and the diameter of the limit portion 5311 is larger than the diameter of the connection portion 5313. One end of the connection portion 5313 away from the limit portion 5311 is connected to the first conical fastener 532, and the second conical fastener 533 is movably sleeved on the connection portion 5313. When in the locked state, the movable member 14 is clamped on the outer surface of the connection portion 5313. Furthermore, when the second conical fastener 533 is pushed by the movable part 14 in the initial state and before the locking state, the second conical fastener 533 can be abutted against the limiting portion 5311, and the limiting portion 5311 can have the effect of maintaining the relative movable stroke of the second conical fastener 533 on the connecting column 531, thereby limiting the moving distance of the second conical fastener 533, and ensuring the relative distance between the second conical fastener 533 and the first conical fastener 532 when in the locking state, thereby improving the abutting effect of the second conical fastener 533 on the movable part 14.

[0053] Furthermore, the diameter of the limiting portion 5311 is greater than or equal to the minimum diameter of the second conical fastener 533. This arrangement can prevent the movable part 14 from sliding onto the limiting portion 5311, thereby maintaining the sliding effect of the movable part 14 on the outer surface of the second conical fastener 533.

[0054] In one embodiment of the present invention, Figure 5 , Figure 7 As shown, there are multiple second elastic members 534 , and the multiple second elastic members 534 are arranged at intervals along the circumference of the connecting column 531 .

[0055] In this embodiment, there are multiple second elastic members 534, and multiple second elastic members 534 are arranged at intervals along the circumference of the connecting column 531. The second elastic member 534 can have a reverse force for the tightness of the connecting seat 50 and the filter element assembly 10 in the locked state, and the separation and ejection of the two in the conversion state. When there are multiple second elastic members 534, the multiple second elastic members 534 can have the same elastic force at different positions between the end faces of the connecting seat 50 and the filter element assembly 10, so that the forces at different positions of the connecting seat 50 and the filter element assembly 10 are kept consistent, so that the overall moving distance is kept consistent, and the stability is improved.

[0056] Furthermore, a guide column can be arranged on the surface of the seat body 51 facing the filter element assembly 10, and the guide column is extended along the extension direction of the filter element assembly 10. The second elastic member 534 is sleeved outside the guide column. The guide column can limit the direction of the elastic force of the second elastic member 534, thereby keeping the forces at different positions of the connecting seat 50 and the filter element assembly 10 consistent.

[0057] In one embodiment of the present invention, Figures 1 to 4 As shown, the filter element assembly 10 includes a filter element body 11 and a filter element cover 13. One end of the filter element cover 13 is connected to the filter element body 11, and the other end is provided with a connecting groove 131. The other end of the second elastic member 534 elastically abuts against the other end surface of the filter element cover 13.

[0058] The connecting seat 50 and the filter element cover 13 have a first locking state of the seat body 51 and a second separation state of the seat body 51 .

[0059] In this embodiment, the filter element assembly 10 includes a filter element body 11 and a filter element cover 13. The filter element body 11 includes a housing and a filter element, which is used for installing and fixing the filter element. One end of the filter element cover 13 is connected to the end opening of the housing, and the other end is connected to the connection seat 50. The connection seat 50 is provided with a water inlet channel and a water outlet channel. When the connection seat 50 is connected to the filter element body 11, the water inlet channel is connected to the water inlet of the filter element, and the water outlet channel is connected to the water outlet of the filter element, forming a connection between the connection seat 50 and the filter element assembly 10. The water inlet channel and the water outlet channel can be connected to an external pipeline. The filter element cover 13 can be used as an intermediate connector for connecting the filter element body 11 with an external pipeline, realizing a quick and effective connection.

[0060] In one embodiment of the present invention, Figure 2, Figure 4 , Figure 5 , Figure 7 As shown, there are two movable parts 14 and two first elastic parts 15 , and the connecting groove 131 has two mounting grooves 1311 . The two mounting grooves 1311 are arranged opposite to each other, and one movable part 14 and one first elastic part 15 are correspondingly arranged in one mounting groove 1311 .

[0061] In this embodiment, the number of movable members 14 and first elastic members 15 are both two, the number of mounting grooves 1311 provided in the connection groove 131 is two, the two mounting grooves 1311 are arranged oppositely, and one movable member 14 and one first elastic member 15 are arranged in one mounting groove 1311 correspondingly. The two mounting grooves 1311 are arranged oppositely, and the two movable members 14 and the first elastic member 15 are arranged in two mounting grooves 1311 correspondingly, respectively. When the clamping assembly 53 is inserted into the connection groove 131, the movable members 14 of the mounting grooves 1311 on the opposite sides can simultaneously perform locking and clamping operations on the clamping assembly 53, so that different positions of the filter element cover 13 are simultaneously limited and locked with the clamping assembly 53, thereby improving the locking tightness and effectiveness of the filter element cover 13 and the connection seat 50.

[0062] Furthermore, the number of the mounting grooves 1311, the movable member 14, and the first elastic member 15 can also be three, four, five, etc., which are not limited here.
