As shown in fig. 6, the clip member 140 has a rectangular block structure with an arc-shaped notch 144 formed on one side, and the side of the clip member 140 with the arc-shaped notch 144 is parallel to the moving direction of the sliding member 130. The clamping member 140 is provided with a first guiding through hole 141, the first guiding through hole 141 is a long strip-shaped through hole, the extending direction of the first guiding through hole 141 and the side edge of the clamping member 140, which forms the arc-shaped notch 144, are arranged at a certain angle, that is, the extending direction of the first guiding through hole 141 and the moving direction of the sliding member 130 are arranged at a certain angle, and the first guiding through hole 141 is matched with the guiding column 132 on the sliding member 130. Preferably, the clamping member 140 is further provided with a second guiding through hole 142, the second guiding through hole 142 is a long-strip-shaped through hole, an extending direction of the second guiding through hole 142 is perpendicular to a side of the clamping member 140 where the arc-shaped notch 144 is formed, that is, the extending direction of the second guiding through hole 142 is perpendicular to a moving direction of the sliding member 130, and the second guiding through hole 142 is matched with a connecting bolt or a guiding structure of the end cap 150 (described in detail below). Two or more (even number) of the clamping parts 140 are oppositely arranged, and the two opposite clamping parts 140 are in a symmetrical structure.
As shown in fig. 7, the end cap 150 has the same shape as the end face of the housing 110, and a second through hole 151 is formed in the end cap 150, and the second through hole 151 allows the filter element housing to pass through. The end cap 150 is provided with a coupling hole 152 for coupling with the outer shell 110, and the coupling hole 152 may be coupled with a coupling structure inside the outer shell 110 by a fastener, preferably a bolt. Preferably, four connecting holes 152 are provided to correspond to the second guide through holes 142 of the two clip members 140, respectively, and when the end cap 150 is coupled to the housing 110 by bolts, the bolts are engaged with the second guide through holes 142 to guide the movement of the clip members 140. Further, a guiding structure matched with the second guiding through hole 142 may also be disposed on the end cover 150 or inside the housing 110.
Since the first guiding through hole 141 of the clip member 140 is disposed at a certain angle with respect to the moving direction of the sliding member 130, and the first guiding through hole 141 is matched with the guiding post 132, when the guiding post 132 slides in the first guiding through hole 141, the clip member 140 can be driven to move along the moving direction of the sliding member 130 and in the direction perpendicular to the moving direction of the sliding member 130. However, since the extending direction of the second guide through hole 142 is perpendicular to the moving direction of the sliding member 130, the second guide through hole 142 is engaged with the bolt connected to the cap 150, so that the chucking member 140 can move only in the extending direction of the second guide through hole 142, i.e., in the direction perpendicular to the moving direction of the sliding member 130. The opposing arrangement of the two clip members 140 eventually achieves that the two clip members 140 gradually get closer to or farther away as the sliding member 130 moves.
Further, as shown in fig. 5, in order to avoid the influence of a bolt or a guide structure engaged with the second guide through hole 142 of the clip member 140 when the sliding member 130 slides, an avoiding notch 134 is provided on the sliding member 130, and the avoiding notch 134 has a certain length in the moving direction of the sliding member 130, and preferably, the avoiding notch 134 may be provided as a through hole having a certain length in the moving direction of the sliding member 130.
As shown in fig. 7, preferably, the end cap 152 is further provided with a limit block 153, the position and shape of the limit block 153 correspond to the position and shape of the notch 112 on the housing 110, when the end cap 150 is connected to the housing 110, the limit block 153 enters the notch 112 from the opening of the notch 112, and the limit block 153 and the notch 112 form a hole matching with the shape of the guide block 131 on the sliding member 130, so as to guide the movement of the guide block 131.
As shown in fig. 8, when the housing 110 is rotated to a first position relative to the connection structure (in which the filter cartridge is vertically disposed), the sliding member 130 is located at a right position, in which the two clip members 140 are closest to each other, and the edges of the arcuate notches 144 of the two clip members 140 can clip the filter cartridge housing such that the filter cartridge housing cannot be separated from the filter cartridge housing mounting structure 100.
As shown in fig. 9 and 10, when the outer shell 110 rotates to the second position relative to the connection structure, the sliding member 130 is located at the left position, and the two clip members 140 are farthest away, at this time, the edges of the arc-shaped notches 144 of the two clip members 140 cannot be engaged with the filter cartridge housing 200, and the filter cartridge housing 200 can be separated from the filter cartridge housing installation structure 100.
Further, an elastic member 160 is disposed between the two clip members 140, as shown in fig. 6, an elastic member mounting groove 143 is disposed on the clip member 140, and the elastic member 160 is located in the elastic member mounting groove 143. When the sliding member 130 is located at the right side, the elastic member 160 is in a compressed state, and when the sliding member 130 moves from the right side to the left side, the amount of compression of the elastic member 160 is reduced, and at the same time, the elastic member 160 provides thrust to the two clamping members 140, so that the sliding member 130 moves from the first position to the second position in a labor-saving manner. Preferably, the elastic member 160 is a spring.
It can be understood that the two clamping components are not limited to move simultaneously, and can also be fixed, and the other clamping component can move relative to the fixed clamping component under the driving of the connecting structure, so that the clamping and releasing of the filter element shell can also be realized.
The invention provides a water purifier, as shown in fig. 10 and 11, the water purifier comprises the filter element housing installation structure 100, a clamping groove 210 is arranged at the end part of a filter element housing 200 of the water purifier, and the clamping groove 210 is matched with two clamping components 140 in the filter element housing installation structure 100 to realize clamping and separation of the filter element housing 200 and the filter element housing installation structure 100.
As shown in fig. 10, when the cartridge housing 200 rotates the housing 110 to the second position, the cartridge housing 200 can be separated from the cartridge housing mounting structure 100. When the filter cartridge housing 200 is perpendicular to the first connection structure 121 or the second connection structure 122, that is, the housing 110 rotates to the first position, the filter cartridge housing 200 is clamped to the filter cartridge housing installation structure 100. As shown in fig. 12, when the housing 110 is rotated to the first position, the edge of the arc-shaped notch 144 of the clip member 140 is located in the clip groove 210 of the filter cartridge housing 200, and the two clip members 140 cooperate to engage with the clip groove 210.
The filter element shell mounting structure provided by the invention can realize clamping connection or separation with the filter element shell by overturning the shell and the connecting structure, so that the filter element shell is more convenient and faster to mount and dismount. The filter element shell can be disassembled and assembled through simple overturning, inserting and pulling actions, so that the filter element replacement does not need to be operated by professional personnel any more, and the cost for replacing the filter element is saved.
