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 integrally injection molded, and a plurality of straight pipes are molded on the member body, and straight channels are core-pulled and molded in the straight pipes, wherein the straight pipes are circular pipes, and the straight channels are correspondingly arranged as circular channels.

In this embodiment, the component body is an injection molded part formed by integral injection molding, and all flow channels in the component body are direct flow channels formed by core pulling, 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 poorly welded and even are scrapped can be effectively avoided, thereby improving the product yield of the integrated waterway component and reducing the mass production cost of the integrated waterway component 2; meanwhile, in the embodiment, the straight pipe formed on the component body is set to be a round pipe, on one hand, the round better shape stability can be utilized to reduce the probability of collapse deformation in the core pulling forming process, on the other hand, the core pulling of the inner round runner can be conveniently realized through a round rod core pulling strip, the die is simple and easy to manufacture, and the preparation cost is lower.

In addition, it should be noted that in this embodiment, the whole integrated waterway component 2 is integrally injection molded, and the straight pipe with the straight channel formed thereon has uniform pipe wall, no welding defect exists, and has good water pressure resistance, thus being beneficial to meeting the requirements of water hammer and explosion test.

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.

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.

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 main 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.

Referring to fig. 2 and 3 together, in the present embodiment, further, the integrated waterway member 2 includes a plurality of first straight pipes 21 extending in a first direction, a plurality of second straight pipes 22 extending in a second direction, and a plurality of third straight pipes 23 extending in a third direction, wherein any two directions of the first direction, the second direction, and the third direction are disposed at an angle to each other; that is, the integrated waterway member 2 integrates at least three direct current channels in different directions, which is a three-dimensional integrated waterway member 2, and can meet the requirement of a complex waterway.

It can be understood that, in the first straight pipe 21, the second straight pipe 22 and the third straight pipe 23, the more similar the extension directions of any two straight pipes are, the easier the core-pulling structures matched with the straight pipes in different directions are to interfere in position in the process of core-pulling forming the internal straight flow channel, so that the setting of the core-pulling structure 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 tube in different directions can be reduced to the greatest extent.

In this embodiment, further, on the integrated waterway component 2, the plurality of straight pipes integrally injection molded further includes a straight switching pipe extending along the fourth direction and communicating with both the first straight pipe 21 and the second straight pipe 22, and a pipe orifice of the straight switching pipe located at the end of the fourth direction is provided with a plug to realize indirect communication between the first straight pipe 21 and the second straight pipe 22; wherein the fourth direction is the opposite direction of the third direction. Of course, in this embodiment, other straight connecting pipes are also formed in the member body, and these straight connecting pipes all have pipe orifices for core pulling, and plugs are disposed in these pipe orifices to limit water outflow through the plugs; the extension direction of the straight connecting pipes can be specifically set according to specific requirements.

In the present invention, the plurality of straight pipes integrally injection molded on the integrated waterway member 2 may further include a fourth straight pipe extending in the fifth direction and/or a fifth straight pipe extending in the sixth direction, 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.

In this embodiment, further, on the integrated waterway member 2, at least part of the outer wall surfaces of two adjacent 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. 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.

In this embodiment, further, when the integrated waterway member 2 is assembled into the water purifier, all the first straight pipes 21 extending in the first direction may be connected by waterway components of one type, all the second straight pipes 22 extending in the second direction may be connected by waterway components of another type, and all the third straight pipes 23 extending in the third direction may be connected by waterway components of another type. That is, for the integrated waterway member 2, the straight pipes with different extending directions are used for connecting waterway components of different types, so that the waterway components of the same type can be intensively connected to 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 of the same type is realized, and the assembly efficiency is improved.
