The invention provides an integrated waterway component which is used for a water purifier.

Referring to fig. 1, in an embodiment of the present invention, the integrated waterway member 2 includes a member body having a plurality of first straight flow passages extending in a first direction and a plurality of second straight flow passages extending in a second direction formed therein; wherein the first direction and the second direction are arranged at an included angle. It can be appreciated that, because the integrated waterway member 2 integrates a plurality of straight flow channels in different directions, compared with the prior art that the connection of various waterway components in the water purifier is realized by adopting independent pipelines and pipeline connectors, the technical scheme saves the assembly steps of connecting the pipelines, thereby improving the assembly efficiency of the water purifier. In this embodiment, all the straight channels formed in the member body extend to the outer surface of the member body, and have the channel ports exposed on the outer surface of the member body, so that each straight channel can be connected with the corresponding other waterway components through the channel ports.

In this embodiment, further, when the integrated waterway member 2 is assembled into the water purifier, all of the first straight flow passages extending in the first direction may be connected by one type of waterway component, and all of the second straight flow passages extending in the second direction may be connected by another type of waterway component. That is, for the integrated waterway member 2, the direct current channels with different extending directions are used for connecting waterway components with different types, so that the waterway components with the same type can be intensively connected on the same side of the integrated waterway member 2 in the water purifier assembled with the integrated waterway member 2, the centralized assembly of waterway components with the same type is realized, and the assembly efficiency is improved.

In this embodiment, further, a plurality of third straight flow passages extending in the third direction are formed in the member body; wherein the third direction and the first direction and the second direction are arranged at an included angle; therefore, the integrated waterway component 2 integrates at least three direct current channels in different directions, is a three-dimensional integrated waterway component 2 and can meet the requirement of a complex waterway.

It can be understood that the more similar the extending directions of any two straight flow channels are in the first straight flow channel, the second straight flow channel and the third straight flow channel, the more easily the core-pulling structures matched with the straight flow channels in different directions interfere in the process of core-pulling and forming the straight flow channels, so that the setting of the core-pulling structures is affected; in this embodiment, preferably, any two directions of the first direction, the second direction and the third direction are perpendicular to each other, so that the position interference possibility of the core pulling structure corresponding to the straight flow channels in different directions can be reduced to the greatest extent.

In this embodiment, the component body is preferably an injection molding piece of an integral injection molding, and all flow channels in the component body are core-pulling molded direct current channels, so, compared with the mode that two base plates are welded into an integrated waterway plate commonly adopted in the prior art, the situation that products are poor in welding and even are scrapped can be effectively avoided, and therefore the product yield of basic waterway components is improved, and the mass production cost of the integrated waterway components 2 is reduced.

In this embodiment, the injection molding material adopted by the member body is preferably a mixed material of POM plastic or PP plastic and glass fiber, and these injection molding materials have high strength, which is beneficial to reducing the probability of collapse deformation of the straight runner in the core-pulling molding process.

Referring to fig. 2 and 3 together, in the present embodiment, further, the member body is integrally injection molded with a plurality of first straight pipes 21 extending in the first direction, a plurality of second straight pipes 22 extending in the second direction, and a plurality of third straight pipes 23 extending in the third direction, and the first straight flow passages, the second straight flow passages, and the third straight flow passages are formed in the first straight pipes 21, the second straight pipes 22, and the third straight pipes 23 in one-to-one correspondence. It can be understood that in this embodiment, the whole integrated waterway component 2 is integrally injection molded, and the straight pipe with the straight runner formed thereon has uniform pipe wall, no welding defect exists, and has good water pressure resistance, thereby being beneficial to meeting the requirements of water hammer and blasting test.

It can be understood that for the wall thickness of the straight pipe formed on the component body, if the wall thickness is too small, collapse deformation easily occurs in the core pulling forming process, if the wall thickness is too large, more materials are needed, and the cost is too high.

Further, in the present embodiment, at least one of the first straight pipe 21, the second straight pipe 22 and the third straight pipe 23 is a circular pipe, and accordingly, at least one of the first straight flow passage, the second straight flow passage and the third straight flow passage is a circular flow passage; and preferably, each straight pipe on the component body is a circular pipe, and the direct current channels formed by core pulling in the straight pipes are respectively arranged as circular channels. It can be understood that the round shape has better tension and better shape stability, so that the straight tube formed on the component body is arranged as the round tube, which is beneficial to avoiding collapse deformation in the core pulling forming process.

In the invention, the diameter range of the straight flow channel formed on the component body is preferably 6mm to 12mm; it can be understood that under the condition that the wall thickness of the straight pipe is certain, if the diameter of the straight flow channel is too large, collapse deformation easily occurs in the core-pulling forming process, and if the diameter of the straight flow channel is too small, the flow requirement of the water purifier is difficult to meet. In this embodiment, the diameter of the straight flow channel formed on the member body is further preferably 10mm, so as to achieve both core-pulling stability and flow requirement of the water purifier.

It can be understood that under the condition that the wall thickness and the inner diameter of the straight pipe are both fixed, the longer the straight pipe is, the longer the core pulling distance is, the more easily collapse deformation occurs in the core pulling process, and the greater the core pulling difficulty is. In this embodiment, further, the length of the straight pipe formed on the member body is less than or equal to 180mm, so as to avoid the overlong straight pipe and ensure the core pulling yield.

In this embodiment, further, on the integrated waterway member 2, a transfer straight runner extending along the fourth direction and communicating with both the first straight runner and the second straight runner is further formed in the member body, and a runner port of the transfer straight runner is provided with a plug to realize indirect communication between the first straight runner and the second straight runner; wherein the fourth direction is the opposite direction of the third direction. Of course, in this embodiment, other switching straight channels are also formed in the member body, and these switching straight channels all have flow passage ports for core pulling, and plugs are all provided in these flow passage ports to limit water outflow through the plugs; the extending directions of the switching straight flow passages can be specifically set according to specific requirements.

In the present invention, the integrated waterway member 2 may further have a fourth straight flow passage extending in the fifth direction and/or a fifth straight flow passage extending in the sixth direction formed therein, and may be specifically set according to specific needs; wherein the fifth direction is the opposite direction of the first direction, and the sixth direction is the opposite direction of the second direction.

Further, the outer wall surface of one first straight tube 21 is connected with the outer wall surface of the other first straight tube 21; and/or one first straight pipe 21 is connected with the other first straight pipe 21 through a reinforcing rib 26.

Specifically, in this embodiment, on the integrated waterway member 2, the outer wall surfaces of at least part of the adjacent two straight pipes extending in the same direction are connected to enhance the joint rigidity of the two connected straight pipes, and reduce the probability of bending deformation of the straight pipes in the extending direction thereof. In this embodiment, the integrated waterway member 2 further includes two adjacent straight pipes partially extending in the same direction and arranged at intervals, and in order to reduce the probability of bending deformation in the extending direction, it is preferable to provide reinforcing ribs 26 for connection therebetween. It should be noted that, in other embodiments of the present invention, any two adjacent straight pipes extending in the same direction may be connected by only one of the two connection methods.

Further, the first straight pipe 21 is connected to the second straight pipe 22 or the third straight pipe 23; and/or the first straight pipe 21 is connected with the second straight pipe 22 or the third straight pipe 23 through reinforcing ribs.
