Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

The utility model provides a filter element 10, as shown in figure 1. The cartridge 10 is an in-line cartridge that can be secured to a water purifier, such as to a mounting frame 500 within the water purifier. This mounting frame 500 can be provided, for example, on the top of the water purifier, for locking the cartridge 10 in cooperation with a locking mechanism provided at the end of the cartridge 10 where the handle 300 is located. The top is relative to the position shown in fig. 1, and the position of the mounting frame 500 changes when the water purifier is placed in other orientations. Of course, the mounting frame 500 may not be separately provided as long as a corresponding member (such as a locking groove 510 to be described later) is provided on a side wall of the filter cartridge for receiving the filter cartridge 10 in the water purifier. For ease of understanding, the principle of the present invention will be described below by taking the embodiment shown in fig. 1 as an example.

The mounting frame 500 has a mounting hole for the filter cartridge 10 to pass through, and a locking groove 510 is formed on an inner sidewall of the mounting hole. A locking member 200 is provided on the cartridge 10. The locking groove 510 can cooperate with the locking member 200 to lock the cartridge 10 and the mounting frame 500 together, thereby securely locking the cartridge 10 in the water purifier.

Specifically, cartridge 10 includes a body 100, a lock member 200, and a handle 300, as shown in fig. 1-3. The body 100 may serve as a carrier for the locking member 200 and the handle 300 so that they are coupled to the body 100. The body 100 may also include a filter device (not shown) of the filter cartridge 10, such as a reverse osmosis filter membrane, which is not the focus of the present invention and will not be described in detail.

The locking member 200 is disposed within the body 10 and has a retracted position (as shown in fig. 2) and an extended position (as shown in fig. 3). The locking member 200 is reciprocally movable between a retracted position and an extended position. When the locking member 200 is in the retracted position, the locking member 200 is retracted into the body 100, so that the locking member 200 is withdrawn out of the locking groove 510, thereby releasing the locking relationship between the cartridge 10 and the mounting frame 500. When the locking member 200 is in the extended position, at least a portion of the locking member 200 extends out of the body 100, and the locking groove 510 can receive the extended portion of the locking member 200, thereby locking the cartridge 10 with the mounting frame 500.

The handle 300, which is pivoted on the pivot axis O-O, is pivotably connected to the locking member 200. The handle 300 has a snap-fit position and an open position. The fastening position can be a position where the handle 300 is attached to the upper inclined surface of the filter element 10, so that after the filter element 10 is locked in the installation frame 500, the handle 300 is tightly attached to the upper end surface of the filter element 10, the use of a user is not affected, and the user cannot touch the handle by mistake. The open position may be a position where handle 300 is rotated to enable removal of cartridge 10 from mounting frame 500. Illustratively, the handle 300 may be perpendicular to the end surface of the body 100 when the handle 300 is in the open position. This is more ergonomic and facilitates the user in removing the cartridge 10 from the mounting frame. Of course, the snap-fit position and the open position may be in other directions or angles, and are not described in any greater detail herein. It is certain that the handle 300 can be rotated between the snap-fit position and the open position.

As shown in fig. 4, the lock member 200 is provided with a first engagement portion 210, and the handle 300 is provided with a second engagement portion 310. Wherein the first engaging portion 210 and the second engaging portion 310 engage with each other to move the locking member 200 from the extended position to the retracted position when the handle 300 is pivoted from the fastening position to the opening position. That is, the circumferential movement of the handle 300 about the pivot is converted into the linear movement of the locking member 200 by the mutual engagement of the first and

second engagement portions

210 and 310.

In a preferred embodiment, the first and second

fitting parts

210 and 310 may have a groove and protrusion structure, which will be described in detail below.

In another embodiment, as shown in fig. 5, the first and second

fitting portions

210 and 310 may also be in a rack and pinion configuration. Wherein the first mating portion 210 'may be a rack and the second mating portion 310' may be a gear. The circular motion of the second fitting portion 310 'of the gear structure may be converted into the linear motion of the first fitting portion 210' of the rack structure by the gear and rack being engaged with each other.

Thus, when the user removes the filter cartridge 10 from the water purifying device, the handle 300 can be rotated to the open position, and at this time, the axial movement of the handle 300 is converted into the linear movement of the locking member 200 by the mutual engagement of the second engaging portion 310 of the handle 300 and the first engaging portion 210 of the locking member 200. As a result, the locking member 200 is withdrawn out of the locking groove 510 and retracted into the filter cartridge 10, thereby releasing the locking relationship between the filter cartridge 10 and the mounting frame 500. The user can remove the cartridge 10 from the water purifier by pulling the handle 300.

Preferably, as shown in fig. 4 and 6A-6B, one of the first mating portion 210 and the second mating portion 310 is a recess, and the other is a rotatable protrusion within the recess. In the illustrated embodiment, the first mating portion 210 is a groove and the second mating portion 310 is a protrusion. The principle will be explained below by taking the illustrated embodiment as an example.

It should be noted that the embodiment shown in fig. 4 is different from the embodiment shown in fig. 6A-6B in the number of the first engaging portions 210 and the second engaging portions 310, and the operation principle is basically the same. In contrast, the embodiment of fig. 6A-6B more clearly illustrates the working principle of the first and

second mating portions

210 and 310, and therefore will be described below with reference to fig. 6A-6B.

As shown in fig. 6A, the second fitting part 310 in the form of a groove has a slope 212 inclined with respect to the circumferential direction about the pivot axis O-O. The second mating portion 310 in the form of a protrusion slides along the ramp 212 during pivoting of the handle 300 from the latched position to the open position (i.e., pivoting in the direction of arrow a) to urge the locking member 200 to move from the extended position to the retracted position to unlock the cartridge 10. When the handle 300 is in the snap-fit position, the second mating portion 310 in the form of a protrusion is inserted into the first mating portion 210 in the form of a recess. When the handle 300 is pivoted to the open position and the second mating portion 310 is rotated about the pivot axis O-O in the direction of arrow a, the inclined surface 312 on the protrusion slides along the inclined surface 212, as shown in fig. 6B. The ramp 312 pushes the ramp 212 to move along the direction of arrow M, thereby moving the locking member 200 along the direction of arrow M. In this embodiment, the inclined surface 312 of the second mating portion 310 has the same or similar shape as the inclined surface 212 of the first mating portion 210. The purpose is to achieve a better effect of the pushing action.

Exemplarily, the second fitting part 310 in the form of a groove may be V-shaped as seen in a radial direction extending outwardly perpendicular to the pivot axis O-O. The two faces of the V-shape are a bevel 212 and a bevel 214, respectively. The second fitting portion 310 has only a pushing effect on the inclined surface 212 therein during the rotation of the handle 300. The groove with the V-shaped structure is easy to process.

Of course, in other embodiments not shown, the groove may have other shapes, such as triangular, as long as it has a slope 212.

Illustratively, the second fitting part 310' in the form of a protrusion may also have an elongated configuration as shown in fig. 7. In this case, the inclined surface 212 of the first fitting part 210 will be pushed by the pointed end 313 'of the second fitting part 310'. That is, the second fitting portion 310' may also take various forms of protrusions, which are not illustrated here. As long as the second fitting portion 310 can push the locking member 200 along the inclined surface 312 when rotating in the first fitting portion 210, the circumferential movement of the handle 300 is converted into the linear movement of the locking member 200. On the contrary, the first matching portion 210 is a protrusion, and the second matching portion 310 is a groove, which will not be described again.

In summary, the first and second engaging

portions

210 and 310 have a protrusion and groove structure, so that the circumferential movement of the handle 300 can be converted into the linear movement of the locking member 200, and the method has a simple structure, is easy to process, and can reduce the cost of the product.

Exemplarily, as shown in fig. 8 and 9, the first fitting portion 210 in the form of a groove further has a flat surface 213 connected to the inclined surface 212, the flat surface 213 extending in the circumferential direction. During the rotation of the handle 300 from the fastening position to the opening position, the inclined surface 312 of the second engaging portion 310 in the form of a protrusion slides on the inclined surface 212, thereby pushing the movement of the locking member 200. When the handle 300 is rotated to the open position, the second engaging portion 310 will move to the plane 213, and the tip 313 of the second engaging portion 310 will abut against the plane 213, so as to keep the handle 300 at the open position. That is, when the tip 313 moves to the flat surface 213, the rotation of the handle 300 within a certain angle will not act on the pushing of the locking member 200, and at this time, the locking member 200 also moves just to the retracted position. Also, when the handle 300 is in the open position, the handle 300 may be held in the open position without rotation without application of an external force. Thus, by providing the flat surface 213 in the recess, when the handle is rotated to the open position, the handle 300 can stay in this position even if the user is no longer manipulating the handle 300, without worrying about the handle rotating back to the engaged position due to the reaction force of the inclined surface 212 to the protrusion by loosening the hand.

Illustratively, as shown in fig. 4, 8 and 9, the number of the first fitting portions 210 is two. The two first mating portions 210 are centrosymmetric about the pivot axis O-O. In this case, the flat surface 213 of each first fitting portion 210 is connected to another first fitting portion 210. In this way, since the first engaging portions 210 are two parts that are centrosymmetric, when the handle 300 is rotated, the acting force applied to the first engaging portions 210 by the second engaging portions 310 is symmetric, which is beneficial to improving the stability of each moving element in motion.

The principles of the present invention have been described above by taking the first mating portion 210 as a groove and the second mating portion 310 as a protrusion. As previously described, a groove may also be provided on the handle 300 and a protrusion may also be provided on the locking member 200. In this case, in order to improve the strength of the pin of the handle 300, it may be necessary to increase the diameter of the pin.

Illustratively, the first mating portion 210 is a groove. In this case, the groove extends to the end face of the locking member 200 facing the outer peripheral wall of the cartridge 10, as shown in fig. 4, 6A and 8. I.e., the recess has an opening communicating with the outer peripheral wall of the locking member 200. This facilitates the machining of the recess on the one hand and also facilitates the mounting during the connection of the handle 300 to the locking member 200 on the other hand.

Illustratively, as shown in fig. 4, a pin 320 is provided on the handle 300, a shaft hole is provided on the locking member 200, the first fitting portion 210 is provided on an inner wall of the shaft hole, and the second fitting portion 310 is provided on an outer wall of the pin. By the arrangement, the processing difficulty can be reduced, the yield of products is improved, and the cost is reduced.

In another embodiment, as shown in fig. 10, one of the first mating portion 210 and the second mating portion 310 may be a slide track, and the other may be a slider sliding along the slide track, wherein the slide track and the slider are engaged with each other when the handle 300 is pivoted between the open position and the closed position. For example, as shown in FIG. 10, the first engaging portion 210 "is a slide way, the second engaging portion 310" is a slide block, and the slide block has only freedom in the direction along the O-O axis, and when the slide block rotates around the pivot axis O-O, the slide way can be driven to move along the O-O axis. Conversely, the first mating portion 210 "is a slider and it has only a degree of freedom in the direction along the O-O axis; the second mating portion 310 "is a slide. As the second mating portion 310 "rotates about the pivot axis O-O, the first mating portion 210" will be forced by the ramps to move along the axis O-O.

If the first and second fitting parts 210 'and 310' of this structure are applied to the filter cartridge 10, the locking member 200 can be reciprocated between the retracted position and the extended position only by the rotation of the handle 300. Under the premise of simplified structure, the bidirectional movement of the handle 300 driving the locking piece is also realized. When a user desires to install the cartridge 10 into the water purifier, the handle 300 can be rotated to an open position to retract the locking member 200 into the cartridge 10, and then the water inlet/outlet (not shown) of the cartridge 10 can be aligned with the water inlet/outlet of the water purifier until the locking member 200 is aligned with the locking groove 510 of the mounting frame 500. The handle 300 can then be rotated to the latched position, allowing a portion of the locking member 200 to extend out of the cartridge 10 and be received by the locking slot 510. At this point, locking of the cartridge and mounting frame 500 can be accomplished.

In the embodiment shown in fig. 4, the bidirectional movement of the handle 300 with the locking member can also be achieved by the cooperation of the gear and the rack.

For the embodiments shown in fig. 2-4, 6A-6B, and 7-12, the locking of the cartridge 10 can be accomplished by a reset member. Illustratively, as shown in fig. 2-3, the locking element 200 further includes a reset element 400. The reset member 400 may also be coupled to or abut the locking member 200. The reset member 400 applies a force to the latch member 200 to return from the retracted position to the extended position to latch the filter cartridge 10. When the handle 300 is rotated from the fastening position to the opening position, the locking member 200 is moved from the extended position to the retracted position by the interaction between the first engaging portion 210 and the second engaging portion 310. During the movement of the locking member 200, the kinetic potential energy thereof is converted into the elastic potential energy of the restoring member 400. When the handle 300 rotates from the open position to the closed position, the reset unit 400 converts the elastic potential energy into the kinetic potential energy to return the locking unit 200 from the retracted position to the extended position.

In one embodiment, as shown in fig. 2-3, the return element 400 may be a compression spring. The locking member 200 compresses the spring during movement of the locking member 200 from the extended position to the retracted position, converting kinetic potential energy to elastic potential energy for storage within the spring. During the rotation of the handle 300 from the open position to the engaging position, the first engaging portion 210 and the second engaging portion 310 are no longer constrained to each other, and at this time, the spring converts the elasticity into power potential energy to push the locking member 200 from the retracted position to the extended position.

The restoring member 400 may take various forms such as an elastic member made of an elastic material, a tension spring, a torsion spring (as will be described later). Also, the restoring member 400 may have various kinds as long as its function can be achieved.

Through being provided with the piece 400 that resets, locking piece 200 can be under the mutual constraint effect that does not have first cooperation portion 210 and second cooperation portion 310, makes locking piece 200 be in the state of stretching out, is favorable to more like this locking the filter core 10 in the purifier, reduces the phenomenon of leaking.

Illustratively, as shown in fig. 2 to 3, the locking member 200 is two in number, and is provided corresponding to both ends of the handle 300, respectively. In this case, the reset member 400 is located between the two locking members 200. Thus, on the one hand, the handle 300 is uniformly stressed on the locking member 200 in structure due to the two reset members 400 being oppositely arranged. On the other hand, since the reset member 400 is disposed between the two locking members 200, the reset member 400 can be compressed by the relative movement of the two locking members 200, which is relatively simple in structural design and easy to implement.

Exemplarily, as shown in fig. 11, a fixing shaft 110 is provided between the two locking members 200, and the fixing shaft 110 extends in the axial direction of the filter cartridge 10. The reset member 400 is a torsion spring, which is sleeved on the fixed shaft 110, and two ends of the torsion spring respectively abut against the two locking members 200.
