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 core 100, this filter core 100 are the formula filter core that cut straightly, and it can be fixed to on the purifier or on the installation frame (not shown) in the purifier. This purifier or installation frame all has the cavity, can hold filter core 100, and is provided with the locking groove that can be connected with filter core 100 on the lateral wall of this purifier or installation frame for lock filter core 100 and purifier or installation frame, prevent that filter core 100 from droing from it. Which will be described in detail below.

The cartridge 100 includes a body 200, a lock 300, and a handle 400. The body 200 may serve as a carrier for the lock 300 and the handle 400, allowing them to be attached to the body 200. The body 200 may also include a filter unit (not shown) of the filter cartridge 100, 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 element 300 is disposed within the body 200 and has an extended position (as shown in fig. 1-2) and a retracted position (as shown in fig. 3-4). The locking member 300 is reciprocally movable between an extended position and a retracted position. The direction of movement of the lock 300 is perpendicular to the axis of the cartridge 100. When the locking member 300 is in the extended position, at least a portion of the locking member 300 extends beyond the peripheral wall of the body 200, as shown in fig. 6, and the locking slot 700 can receive the extended portion of the locking member 300, thereby locking the filter cartridge 100 with the water purifier or mounting frame. When the locking member 300 is in the retracted position, the locking member 300 is withdrawn from the locking groove 700, and then the locking member 300 is retracted into the body 200, thereby releasing the locking relationship between the filter cartridge 100 and the water purifier or the mounting frame.

Handle 400 is pivotably connected to body 200 by pivot 410, wherein pivot 410 is perpendicular to the axis of cartridge 100. A first radial dimension a of at least a portion of the pivot 410 in a first radial direction is greater than a second radial dimension B in a second radial direction. As shown in fig. 5, the structure may be provided in the middle of the pivot 410, or a plurality of the structures may be provided on the pivot 410.

First, a position where the handle 400 is pivoted to a first radial direction parallel to the movable direction of the locking member 300 is defined as a first position, such as the snap-fit position shown in fig. 1-2. The position when the handle 400 is pivoted to the second radial direction parallel to the movable direction of the locking member 300 is defined as the second position, for example, the open position shown in fig. 3-4.

When the handle 400 is in the first position, the handle 400 utilizes the portion of the pivot 410 having the larger radial dimension to push the locking member 300 away from the pivot 410 until the locking member 300 is in the extended position, as shown in FIGS. 1-2. The cartridge 100 can be locked to the water purifier by means of the extended locking member 300.

When the handle 400 is in the second position, the radial dimension of the pivot 410 of the handle 400 in the direction of movement of the locking member 300 is small, creating a clearance between the locking member 300 and the pivot 410. In one embodiment, the locking member 300 may be provided in a shape having a chamfer 301 at a portion protruding out of the body 200, as shown in fig. 6. That is, when the user takes out the filter cartridge 100 from the cavity of the water purifier or the mounting frame, the locking member 300 moves the locking member 300 to the retracted position by the pushing action of the chamfer 301 and the locking groove 700 of the locking member along with the process of taking out the filter cartridge 100. Filter element 100 is randomly removed. There is also a preferred embodiment, which will be described in detail below.

Thus, when the user is installing filter element 100 on the water purifier, the water inlet and outlet of filter element 100 and the water inlet and outlet of the water purifier can be aligned and connected, after the connection is determined, handle 400 is rotated from the second position to the first position, and along with the rotation of handle 400, locking member 300 is also moved from the retracted position to the extended position. A portion of the locking member 300 protrudes outside the filter cartridge 100 and is inserted into a locking groove 700 of the water purifier or the mounting frame, thereby locking the filter cartridge 100 with the water purifier or the mounting frame. The water leakage phenomenon of the water purifier caused by the falling of the filter element 100 in the use process is prevented.

Therefore, the utility model discloses a set up the pivot of handle 400 as at least partly first radial dimension and be greater than the second radial dimension, from this, handle 400 can promote the locking piece and remove to stretching out the position at the pivot in-process to just can realize the locking of filter core 100 with the purifier through pivot handle 400, its operation is simple, and its structure itself is also simple. Meanwhile, through the structure, whether the filter element 100 is installed in place can be judged, and the water leakage phenomenon caused by the fact that the filter element is not installed in place is also prevented.

Illustratively, during pivoting of handle 400, the at least a portion of pivot 410 may interfere with the inner end surface of locking member 300 to urge locking member 300 to the extended position. The pivot 410 is located at the inner side of the locker 300 in the moving direction of the locker 300. An intermediate member may be provided between the lock 300 and the pivot 410 through which the pivot 410 interacts with the lock 300 during pivoting to urge the lock 300 to move to the extended position to lock the cartridge 100. However, this results in a complicated structure. Therefore, it is preferable that the pivot 410 directly acts on the inner end surface of the locking member 300 during the pivoting of the handle 400, thereby simplifying the product structure.

Illustratively, as shown in FIG. 5, at least a portion of the pivot 410 has a protrusion 413. The protrusion 413 extends outward in a first radial direction. The protrusion 413 may interfere with the inner end surface 302 of the locking member 300 through the first end surface 411 and the second end surface 412 during the pivoting of the handle 400. When the first end surface 411 interferes with the inner end surface 302 of the locking member 300, the locking member 300 is pushed to the protruding position.

This structure can easily realize the conversion of the circumferential movement of the handle 400 into the linear movement of the locking member 300. Simple structure, convenient processing and easy realization.

Illustratively, the filter cartridge 100 further includes a rotational reset element (not shown). The rotating reset element may apply a circumferential force to the handle 400, and the direction of the circumferential force may be the direction in which the handle 400 moves from the second position to the first position. In summary, the rotary reset may maintain the pivot 410 of the handle 400 at a position where the first radial direction is parallel to the movable direction of the locking member 300.

In one embodiment, the rotating reset element may be configured such that when the handle 400 is rotated to the first position, the elastic potential energy of the rotating reset element is just released. The handle 400 thus remains in the first position and does not continue to be rotated by the rotating reset member. In another embodiment, the rotating reset element retains a portion of the elastic potential energy when the handle 400 is rotated to the first position. However, the handle 400 is already attached to the end surface of the filter element 100, i.e., is engaged with the end surface of the filter element 100, and cannot rotate any more. A portion of the potential energy retained by the rotating reset element enables the handle 400 to be more closely attached to the end face of the filter cartridge 100. The handle 400 is prevented from being rotated to be erected without being subjected to an external force and being erroneously touched by a user.

Therefore, by arranging the rotary reset piece, the handle 400 can be kept at the first position after the user finishes installing the filter element 100, and then the locking piece 300 is kept at the extending position, so that the filter element 100 and the water purifier or the installation frame are kept in a locked state. Further, the water leakage phenomenon caused by that the filter element 100 is loosened in the using process and separated from the water purifier due to the fact that the handle 400 is separated from the first position and is touched by a user by mistake can be prevented.

Illustratively, the rotary return member is a torsion spring. The torsion spring may be sleeved on the pivot 410. One end of the torsion spring is connected to the handle 400, for example to a pivot 410 of the handle 400. And the other end may be connected to the body 200. Thus, the torsion spring stores elastic potential energy when the handle 400 is rotated from the first position to the second position relative to the body 200. When the user releases his or her hand or no longer acts on the handle 400, the torsion spring releases the elastic potential energy, forcing the handle 400 to rotate to the first position. The torsion spring is a standard component, so that the cost is low, and meanwhile, the installation between the handle 400 and the body 200 is convenient.

Illustratively, the filter cartridge 100 further includes a first translational reset 500. The first translational reset member 500 may return the locking member 300 from the extended position to the retracted position. Illustratively, the pivot 410 may have a first end surface 411 and a second end surface 412 disposed opposite to each other. When the handle 400 rotates from the first position to the second position, the contact surface with the locking member 300 is changed from the first end surface 411 to the second end surface 412, and the second radial dimension B of the oppositely disposed second end surface 412 is smaller than the first radial dimension a of the oppositely disposed first end surface 411, so that the locking member 300 is moved by the first translational reset member 500 to a direction close to the pivot 410, i.e., from the extended position to the retracted position. Until locking member 300 is retracted into cartridge 100, the locking relationship between cartridge 100 and the water purifier is released. Thus, the user can release the locking relationship of the filter element 100 by rotating the handle 400 from the first position to the second position, thereby simplifying the process of detaching the filter element 100 and improving the user experience. Alternatively, the number of the first end surface 411 and the second end surface 412 on the pivot 410 is not limited to the embodiment shown in the drawings, and may be one or more than two as long as the function thereof can be achieved.

Preferably, the first translational reset member 500 may also be coupled to or abut between the locking member 300 and the sidewall 201 of the body 200, as shown in fig. 1-4. The pushing of the latch member 300 from the extended position to the retracted position by the first translational reset member 500 may push the latch member 300 to retract into the filter cartridge 100 when the handle 400 is rotated to the second position. Thereby unlocking filter cartridge 100 from the water purifier. The process of the user disassembling the filter element 100 is simplified, and the user experience is improved. Meanwhile, the mounting structure of the first translational reset member 500 is relatively simple and easy to implement.

Illustratively, the handle 400 has an arc-shaped segment 420, and both ends of the pivot 410 are connected to both ends of the arc-shaped segment 420, respectively, to form a D-shaped structure. The user can manipulate the arc segment 420 to rotate the pivot 410. The operation of the user is convenient.

Illustratively, the locking member 300 is two in number, one on each side of the handle 400. When the handle 400 is rotated between the first position and the second position, the locking members 300 can be simultaneously moved between the extended position and the retracted position. On one hand, by the locking member 300 being oppositely disposed, it is ensured that the pivot 410 disposed at the center is uniformly stressed and moves smoothly during the process that the pivot 410 pushes the locking member 300 to move by rotating. On the other hand, the two oppositely arranged locking members 300 are more stable when the filter element 100 is locked with the water purifier, so that the water leakage phenomenon caused by the infirm installation of the filter element 100 is further reduced.

Illustratively, the filter cartridge 100 further includes a second translational reset 600. The second translational reset member 600 is located between the two locking members 300, and by virtue of its pulling force, the locking members 300 can be returned from the extended position to the retracted position. Since the inner space of the body 200 of the filter cartridge 100 is limited, if the elastic force of the first translational reset piece 500 is increased, the volume of the first translational reset piece 500 may be increased, and thus the volume of the body 200 may be increased. Therefore, with the first translational reset member 500, a second translational reset member 600 may be added for use with the first translational reset member 500. In this way, the effect of the locking element springing back from the extended position to the retracted position can be improved without increasing the volume of the body 200. Of course, it is also possible to provide no first translational reset member 500, only the second translational reset member 600, thereby returning the locking member 300 to the retracted position by the second translational reset member 600. Thereby providing the user with a variety of options.

In another embodiment, a water purifier is further provided, wherein a locking groove 700 is formed on the water purifier, and can accommodate the locking member 300 protruding outside the filter element 100, so as to lock the filter element 100 and the water purifier. This purifier still includes any kind of filter core as above, no longer gives unnecessary details.
