Compared with the technical scheme that the filter element can be assembled and disassembled with the waterway plate 1 only by rotating the filter element in the prior art, the application can be disassembled and replaced by pushing the filter element assembly along the linear direction, the pushing of the filter element along the linear direction is a simpler and visual operation mode, and a user only needs to push the filter element to be in butt joint with or separated from the waterway plate 1, so that the complexity of the user operation is reduced, and the assembling and disassembling process is more convenient and quick. Moreover, the operation mode of pushing along the straight line is easier to understand and operate by common users, does not need additional training or guidance, and has better user friendliness. Moreover, for the large-flux filter element, the outer diameter of the large-flux filter element is increased compared with that of the small-flux filter element, the mode of rotating and disassembling the filter element is unfavorable for a user to operate the filter element by one hand, the mode of linear ejection is convenient and easy to operate, the single-hand operation can be realized, and the convenience of the user for replacing the filter element is improved.

In addition, for the technical solution of rotary installation of the filter element in the prior art, the rotary installation generally requires that the filter element and the waterway plate are designed with structures related to mechanical rotation, and such structures are easy to wear or damage in the screwing process for a long time, and the abrasion risk can be reduced in the manner of pushing along a straight line in the application.

In summary, pushing the cartridge in a straight line to effect removal and replacement of the cartridge provides a more convenient, reliable and user-friendly cartridge installation and removal process.

As a preferred embodiment of the present application, as shown in fig. 4 to 7, the first guide groove includes a first chute section and a second chute section which are sequentially disposed in communication in the feeding direction of the guide member 4, a locking groove 219 for locking the guide member 4 is formed at a connection position of the first chute section and the second chute section, and the guide member 4 moves along the first chute section to have a pushing stroke and moves along the second chute section to have a withdrawing stroke.

The design of the first chute section, the second chute section and the locking groove 219 enables a fast and accurate movement of the guide 4 and an accurate locking in the locked position, thereby ensuring a fast and reliable connection between the filter flask 3 and the waterway plate 1. Moreover, the pushing stroke is used for installation, the withdrawing stroke is used for disassembly, and the user can quickly and conveniently replace the filter element assembly through the guide piece 4 with the pushing stroke and the withdrawing stroke, so that the convenience of the core replacement operation is improved, and the user is facilitated to maintain and replace the filter element more easily at regular intervals, so that the long-term effectiveness of the water purifier is ensured.

In a specific embodiment, as shown in fig. 3 to 7, one end of the guide member 4 protrudes from the rotating member 5 to form a guide protruding portion, the first chute section and the second chute section are of a concave structure, the guide protruding portion extends into the first chute section and moves along the first chute section to have a pushing stroke, the guide protruding portion extends into the second chute section and moves along the second chute section to have an withdrawing stroke, and when the guide protruding portion moves to a connecting position of the first chute section and the second chute section, the guide protruding portion is blocked into the locking groove 219 and is in locking engagement with the locking groove 219, thereby locking the filter flask 3 and the bracket 2, and thus locking the filter flask 3 and the waterway plate 1.

As a preferred example of the present embodiment, as shown in fig. 5 to 7, the first chute section includes a first straight line section 23, a first bending section 24 and a second bending section 25 which are sequentially communicated, the second chute section includes a third bending section 26, a fourth bending section 27 and a second straight line section 28 which are sequentially communicated, and a locking groove 219 is formed at a connection position of the second bending section 25 and the third bending section 26; the cartridge assembly also has an extreme position against the support 2 to be restrained from movement, in which the ejection mechanism acts on the filter flask 3 to move the filter flask 3 from the extreme position to the locked position or from the unlocked state into the exit stroke.

The multistage design of first spout section and second spout section for the filter core subassembly only need be along straight line direction ejector pin filter flask 3 in installation and dismantlement in-process, and the filter core subassembly can be according to the orbit removal of predetermineeing, and guide 4 can drive the feeding of filter flask 3 along straight line direction along the multistage structure slip of first spout section and second spout section promptly, makes the operation more convenient, and the whole operation process is lower relatively to the requirement of operating space, can reduce the requirement of filter core assembly and water purifier in the application to outside service environment.

The design of the locking groove 219 ensures that the cartridge assembly is securely locked against accidental loosening or movement during normal use. The ejection mechanism can act on the filter flask when the filter element assembly is propped against the bracket 2 so as to enable the filter flask to move from a limiting position to a locking position or enter an exit stroke from an unlocking state, so that the installation and the disassembly of the filter element assembly are more controllable and reliable. In addition, setting of the limit position can give the user obvious in-place hand feeling, prompt the user to loose hands, improve the explicit effect and improve the core replacement experience of the user.

As shown in fig. 5 to 7, specifically, when the filter element assembly is installed to the waterway board 1, the guide member 4 enters the first straight line section 23 along the inlet 21, the filter bottle 3 is pushed to move the guide member 4 along the first straight line section 23 and drive the filter bottle 3 to do straight feeding motion along the direction parallel to the first straight line section 23, when the guide member 4 moves to the transition position of the first bending section 24 and the second bending section 25, the filter bottle 3 moves to the limit position which can not be pushed forward any more, at this time, the user releases his hand, the ejection mechanism applies force to the filter bottle 3 to drive the filter bottle 3 to move, so that the guide member 4 is driven to move from the transition position of the first bending section 24 and the second bending section 25 to the connection position of the second bending section 25 and the third bending section 26, and the guide member 4 falls into the locking groove 219 and is locked with the locking groove 219, so that the filter bottle 3 enters the locking position. When the filter element assembly needs to be disassembled, the filter flask 3 is pushed to move the filter flask 3 forwards along the direction parallel to the first straight line segment 23, the guide piece 4 is separated from the locking groove 219, the filter flask 3 enters an unlocking state from the locking position, at the moment, the ejector mechanism is released, force is applied to the filter flask 3 to drive the filter flask 3 to move, the guide piece 4 is driven to slide along the third bending section 26, the fourth bending section 27 and the second straight line segment 28 in sequence, the filter flask 3 is driven to withdraw backwards along the direction parallel to the second straight line segment 28 until the guide piece 4 is separated from the outlet 22, and the filter flask 3 is disassembled.

The guide member 4 is moved from the first bending section 24 to the second bending section 25, and the backward withdrawing stroke of the second bending section 25 is realized by the acting force of the ejection mechanism, so as to avoid the guide member 4 from reversely moving to obstruct the disassembly and assembly of the filter element during the moving process, the following preferred embodiment can be adopted to realize the unidirectional movement of the guide member 4.

As shown in fig. 5 to 7, the first bending section 24 and the second bending section 25 have a first inner inflection point 29 and a first outer inflection point 210 at the connection position, the first outer inflection point 210 is located on the downstream side of the advancing stroke as compared to the first inner inflection point 29, so that the first inner inflection point 29 and the first outer inflection point 210 are arranged in a staggered manner, and the lateral dimension between the first inner inflection point 29 and the first outer inflection point 210 is larger than the radius of the guide 4 to form a first corner. The second bending section 25 and the third bending section 26 have a second inner inflection point 211 and a second outer inflection point 212 at the connection position, the second inner inflection point 211 being located on the downstream side of the push stroke as compared to the second outer inflection point 212 such that the second inner inflection point 211 and the second outer inflection point 212 are arranged in a staggered manner, and the lateral dimension between the second inner inflection point 211 and the second outer inflection point 212 is larger than the radius of the guide 4 to form a second corner. The third bending section 26 and the fourth bending section 27 have a third inner inflection point 213 and a third outer inflection point 214 at the connection position, the third inner inflection point 213 being located on the upstream side of the withdrawal stroke than the third outer inflection point 214 such that the third inner inflection point 213 and the third outer inflection point 214 are arranged in a staggered manner, and a lateral dimension between the third inner inflection point 213 and the third outer inflection point 214 is larger than a radius of the guide 4 to form a third corner. The guide 4 moves unidirectionally along the first, second and third corners, respectively.

The definition of the lateral dimensions of the inner and outer inflection points at the corners and the radius dimensions of the guide 4 may define a definition for the movement of the guide 4 during the movement of the guide 4 such that it can only move in a single direction and not in the opposite direction. Taking the first corner as an example, the transverse dimension between the first inner inflection point 29 and the first outer inflection point 210 is greater than the radius of the guide 4, so that when the filter flask 3 is in the limit position, most of the structure of the guide 4 moves between the downstream side of the first inner inflection point 29 and the upstream side of the first outer inflection point 210, and when the ejection mechanism acts on the guide 4, the guide 4 can be estimated to the second bending section 25 where the downstream side of the first inner inflection point 29 is located, and the first inner inflection point 29 forms a stop limit for the guide 4, so that the guide 4 cannot retract to the first bending section 24, but can only slide along the second bending section 25 to enter the locking groove 219.

Specifically, the first bending section 24, the second bending section 25, the third bending section 26 and the fourth bending section 27 integrally form a W-like structure, and are limited by the respective inflection points and the dimensions at the corners to achieve the retaining effect on the guide 4. By this arrangement, the guide 4 can be prevented from reversing to affect smooth installation of the filter flask 3 after the hand is loosened. According to the embodiment, the guide piece 4 can be guided in a unidirectional motion through the special structural design of the first guide groove without adding other additional parts, the structure is simple and reliable, the manufacturing cost is low, and therefore the production and manufacturing cost is reduced.

Of course, the first bending section 24, the second bending section 25, the third bending section 26 and the fourth bending section 27 may also form other shaped structures.

As a preferred embodiment of the present application, as shown in fig. 1 and 4, the support 2 is a sleeve, and when the guide member 4 is located in the second chute section, the ejection mechanism can act on the filter flask 3 to drive the filter flask 3 to move, so that one end of the filter flask 3 is pulled out from the sleeve.

The support 2 of sleeve form can provide abundant structural basis for the arrangement of first guide slot on the one hand to provide abundant direction for the removal of guide 4, help the quick and convenient installation of filter element assembly, on the other hand can also realize the hidden arrangement of filter element assembly, avoid filter element assembly installation and the in-process of dismantling to take place to interfere with other spare parts in the water purifier, further promoted filter element assembly's the efficiency of installing and removing. Still further, when the guide piece 4 is located the second spout section, ejection mechanism can act on filter flask 3 in order to drive filter flask 3 and remove and make the one end of filter flask 3 deviate from the sleeve to can make things convenient for the user application of force in order to take out filter element assembly from the sleeve in, further promoted dismantlement efficiency.

As a specific example of this embodiment, as shown in fig. 1 and 4, the sleeve has a first open end 215 into which the filter flask 3 is inserted, and a second open end 216 through which the second water port of the filter flask 3 is in abutting communication with the first water port 11 of the waterway plate 1, and the second open end 216 is spaced from the waterway plate 1 so as to leave a movement space in which the filter flask 3 is moved from the limit position to the lock position, and the filter flask 3 is switched from the lock position to the unlock state.
