The design of the plurality of interface interfaces formed facilitates the arrangement of multiple interfaces to facilitate more compact and rational placement of components within the device.

For example, please refer to FIG. 2 , which is a schematic diagram showing the internal structure of a water purification device according to another exemplary embodiment. In FIG. 2, the water purification apparatus may include an integrated waterway module 2, a control valve, a booster pump 3, and a filter cartridge set 4.

At the same time, the pump bracket 31 of the integrated waterway module 2 and the booster pump 3 is provided with a connection structure, and the pump bracket 31 can be integrally connected by the connection of the fasteners such as screws and the integrated waterway module 2. The integrated waterway module 2 supports the fixed booster pump 3 through the pump bracket 31 at the bottom, thereby avoiding the direct pressure of the booster pump 3 directly on the integrated waterway module 2, resulting in insufficient welding of the integrated waterway plate and the integrated waterway body, and water seepage The problem.

A plurality of bottom brackets 26 may be integrally formed or assembled outside the integrated waterway module 2 to support the respective filter elements in the filter cartridge group 4, respectively. At least one buckle for fixing the external circuit is installed outside the integrated waterway module, and the buckle form may be a C-clip or other existing cable organizer to regulate various power lines and signal lines in the water purification equipment.

In the integrated waterway module, at least two flow channels are respectively located on different planes, wherein the extending direction of the flow channel in one plane intersects with the extending direction of the flow channel on the other plane, and the flow direction of the inner mold is between the flow paths. Interlaced on each other. This structure is inconvenient for direct injection molding in the injection molding process because it is inconvenient to mold. The integrated water channel module 2 has such a structure that the inner cavity flow path intersects. One implementation method is block injection molding, and the other implementation mode is 3D printing molding, and of course, it can also be selected by combining molding molding and machining.

For example, please refer to FIGS. 3A-3C , which are schematic diagrams showing an integrated water circuit module structure according to another exemplary embodiment. In FIG. 3A, the integrated waterway module 2 in the present embodiment can be generally square, and the outer side of the integrated waterway module 2 is six interface interfaces 2A. In other embodiments, the integrated waterway module 2 can also be selected as other polyhedrons, and the number of interface interfaces 2A is not limited.

In FIG. 3A, the integrated waterway module 2 includes a body 22, a lower cover body 23 and an upper cover body 24. The lower cover body 23 and the upper cover body 24 respectively cover the upper and lower surfaces of the body 22, and of course On two adjacent surfaces, such as the side Face and top, of course, more covers can be used. In this embodiment, the body 22 and the lower cover body 23 and the upper cover body 24 are sealingly fixedly connected integrally.

A plurality of flow paths 21 may be integrally formed in the integrated waterway module 2 to facilitate the sequential communication of the components. Each interface interface 2A is formed with a plurality of interfaces 25, each of which may include an access or take-off interface of the control valve, the booster pump 3 or the filter cartridge 4. The interface of the control valve, booster pump 3 or filter cartridge 4 is divided into a water inlet and a water outlet. The plurality of flow paths 21 are respectively connected to the respective interfaces in the order required by the design.

As shown in FIG. 3A, the integrated waterway module 2 has two waterway layers 210 and a connection zone 220. The waterway layer 210 has a plurality of flow channels 21 therein, and the plurality of flow channels 21 in the waterway layer extend in the same plane. The connecting region 220 has a plurality of flow channels 21, and the extending direction of each of the flow channels 21 in the connecting region may be perpendicular or obliquely intersecting with the planar direction of the waterway layer 210. In the embodiment, vertical intersecting is taken as an example. Each of the flow passages 21 in the connection region 220 communicates with each of the interfaces 25 and the flow passages 21 in the water passage layer 210.

As shown in FIGS. 3A and 3C, the connection region 220 is located between the two waterway layers 210, and each of the flow channels 21 in the connection region 220 communicates with at least the first-class channel 21 of each waterway layer. Moreover, each of the flow channels in the connecting region 220 has the same extending direction, and the extending direction may be the same as the direction of the mold-removing after the injection molding, so as to facilitate the parting. At least one end of each flow channel 21 in the connection zone 220 is connected to the first-class track 21 in the waterway layer to facilitate the push-in and exit of the molding die.

Two waterway layers 210 are respectively located between the lower cover body 23 and the body 22, and between the upper cover body 24 and the body 22. Therefore, the groove shape of the two water channel layers 210 can be respectively formed on the main body 22 or the lower and

upper cover bodies

23 and 24, and then the body 22 and the lower cover body 23 and the upper cover body 24 are sealed and connected. Complete waterway layer 210. The body 22, the lower cover 23 and the upper cover 24 can be respectively injection molded, and then the three can be fixedly coupled together. The body and the cover may be ultrasonically welded, may be glued, may be snap-fitted, or may be connected by fasteners such as bolts.

Thus, since the water channel layer 210 in which the plurality of flow paths are horizontally arranged is formed on the open end surface of the body 22, the molding core does not protrude into the interior. The cores forming the multiple flow paths in the connection region 220 are pointed inwardly in the same direction, and no interference occurs. The utility model can solve the problem that the multi-layer inner cavity waterway cannot be normally divided during injection molding, and the injection mold of the main body 22 can adopt upper and lower split molds, or can adopt upper, lower, left and right multi-directional split molds, and the inner molding core does not. Will be stuck.

The body and the cover can also be a double-molded injection-inlaid connection. For example, after separately molding the main body 22, the lower cover body 23 and the upper cover body 24, the main body 22, the lower cover body 23 and the upper cover body 24 are placed in a mold, and injection welding is performed at the joint of the three. Since the internal pressure requirement of the water purifying equipment pipeline in the present disclosure is high, the pipeline needs to bear a large pressure, and an implementation manner is that, in one molding, a side seam is reserved on both sides of the joint sealing body of the body and the cover body. Forming a hollow joint for integral injection and fusion of the rubber during the second injection molding. After the body 22, the lower cover body 23 and the upper cover body 24 are put into the mold, the joint strength is greatly improved after the injection welding of the three joints, and the sealing failure between the flow passages 21 due to excessive pressure is avoided.

The main body and the cover body are double-molded and injection-inlaid, so that the flow passages of the integrated waterway module have better sealing performance and the pressure resistance performance is greatly improved. At the same time, the overall strength of the integrated waterway module is enhanced.

Another embodiment of the present disclosure is mainly directed to a runner design in which the flow passages have different cross-sectional areas along different regions from one end to the other end, thereby changing the pressure loss of the water flow in the flow passage, which is advantageous for improvement. Water output, At the same time reduce the power demand to drive the water flow.

In a possible implementation manner, the two ends of the flow channel are respectively a water inlet portion and a water outlet portion, and at least one expansion portion is disposed between the water inlet portion and the water outlet portion, and the cross-sectional area of the expansion portion is larger than the water inlet The cross-sectional area of the section and the outlet. That is to say, the cross-sectional area of the water inlet portion, the water outlet portion and the expansion portion of the flow passage are not equal, and the cross-sectional area of the expansion portion of the middle portion is increased, thereby reducing the pressure loss of the water flow in the flow passage. Increased water output and reduced power demand to drive water flow.

For example, as shown in FIG. 5, FIG. 8 and FIG. 9, FIG. 5 is a side view of an integrated waterway module according to an exemplary embodiment, FIG. 8 is a right side view of FIG. 5, and FIG. 9 is FIG. A cross-sectional view along the PP plane. An exemplary embodiment of the present disclosure shows at least one flow passage in an integrated waterway module, and FIG. 9 shows two flow passages, a first flow passage and a second flow passage.

The first flow path includes a water inlet portion 211, a water outlet portion 212, and a expansion portion 213 provided between the water inlet portion 211 and the water outlet portion 212. A smooth transition is made between the water inlet portion 211 and the expansion portion 213 and between the expansion portion 213 and the water outlet portion 212. In this embodiment, the cross section of the flow channel is circular. In other embodiments, the cross section of the flow channel may be other polygonal shapes such as an ellipse or a rectangle. The diameter of the water inlet portion 211 is A1, the diameter of the water outlet portion 212 is B1, the diameter of the expansion portion 213 is C1, and C1>A1>B1, that is, the cross-sectional area of the expansion portion 213 is larger than that of the water inlet portion 211. The cross-sectional area, the cross-sectional area of the water inlet portion 211 is larger than the cross-sectional area of the water outlet portion 212, so that the flow path forms a typical small-large-small structure. In this way, the flow rate of water in the first flow passage is slowed, and the friction with the side wall of the flow passage is reduced, thereby contributing to the reduction of water flow loss.

The second flow path includes a water inlet portion 214, a water outlet portion 215, and a expansion portion 216 provided between the water inlet portion 214 and the water outlet portion 215. The water inlet portion 214 and the expansion portion 216 are smoothly transitioned between the expansion portion 216 and the water outlet portion 215. In this embodiment, the cross section of the flow channel is circular. In other embodiments, the cross section of the flow channel may be other polygonal shapes such as an ellipse or a rectangle. The diameter of the water inlet portion 214 is A2, the diameter of the water outlet portion 215 is B2, the diameter of the expansion portion 216 is C2, and C2>B2>A2, that is, the cross-sectional area of the expansion portion 216 is larger than that of the water inlet portion 214. Cross-sectional area and water outlet portion 215. In this way, the flow rate of water in the second flow passage becomes gentle, and the friction with the side wall of the flow passage is reduced, thereby contributing to the reduction of water flow loss. The cross-sectional area of the water outlet portion 215 is larger than the cross-sectional area of the water inlet portion 214, and the flow rate of the water flow at the water outlet portion 215 is smaller than the flow velocity thereof at the water inlet portion 214, so that the instantaneous pressure of the water inlet portion 214 can be alleviated in this manner. The effect of the change on the water pressure at the outlet portion 215.

In other embodiments, the cross-sectional area of the water inlet portion 211 may also be equal to the cross-sectional area of the water outlet portion 212.

For example, as shown in FIG. 9, in the first flow path, the expansion portion 213 is located adjacent to the water outlet portion 212. The angle α between the expansion portion 213 and the water inlet portion 211 is about 100°, and the angle α between the expansion portion 213 and the water inlet portion 211 is in the range of 80° to 180°; the expansion portion 213 is The angle β between the water outlet portions 212 is about 105°, and the angle β between the expansion portion 213 and the water outlet portion 212 is in the range of 80° to 180°. In the second flow path, the expansion portion 216 is adjacent to the water inlet portion 214. The angle θ between the expansion portion 216 and the water inlet portion 214 is about 95°, and the angle θ between the expansion portion 216 and the water inlet portion 214 is in the range of 80° to 180°; the expansion portion 216 is The angle γ between the water outlet portion 215 is about 85°, and the angle γ between the expansion portion 216 and the water outlet portion 215 is between 80° and 180°. The scope is feasible.

The above angles α, β, γ, θ can smoothly transition between the various components of the flow channel, which is beneficial to reduce the friction between the fluid and the side wall of the flow channel, thereby facilitating the reduction of water flow loss.

For example, as shown in FIG. 5 to FIG. 9 , an integrated waterway module according to an exemplary embodiment of the present disclosure includes a plurality of interfaces 25 , one end of which may be respectively connected to the

water inlet portions

211 , 214 and Water outlets 212, 215. The

water inlet portions

211, 214 and the water outlet portions 212, 32 of the flow passage can be connected to the external device through these interfaces 25. Further, the cross-sectional area of the interface 25 is larger than the cross-sectional areas of the

water inlet portions

211, 214 and the water outlet portions 212, 215 to facilitate sealing. Of course, in other embodiments, the cross-sectional area of the interface 25 can also be equal to the cross-sectional area of the water inlet or outlet portion to which it is attached. A part of the interface 25 is temporarily not connected to the

water inlet portions

211, 214 or the water outlet portions 212, 215, but serves as a backup interface, which can be used when an additional flow path is required.

In this embodiment, the cross-sectional area of the flow passage is designed to be unequal, so that the water flow pressure loss in a portion of the flow passage is reduced, which solves the problem of large water flow pressure loss in the flow passage in the related art; in the embodiment of the present disclosure, since the flow passage includes a water inlet portion, a water outlet portion, and at least one expansion portion disposed therebetween, and the cross-sectional area of the expansion portion is larger than a cross-sectional area of the water inlet portion and the water outlet portion, that is, a water inlet portion of the flow passage The cross-sectional area of the region, the water outlet portion and the expansion portion is not equal, and the cross-sectional area of the expansion portion is increased, thereby reducing the pressure loss of the water flow, increasing the water output, and reducing the power demand for driving the water flow.

At the same time, the expansion portion of the above embodiment can also accommodate the water quality sensor probe, and the expansion portion serves as a water flow buffer to improve the stability of the detection data.

Referring to Figure 10, there is shown a cross-sectional schematic view of the installation of a backstop structure at the interface of the flow channel, in accordance with an exemplary embodiment. The backstop structure may be disposed at an interface of the integrated waterway module, and FIG. 10 is a cross-sectional schematic view of the interface for mounting the check valve, according to an exemplary embodiment. In this embodiment, the interface of the check valve installed in the integrated water passage is taken as an example for description. The arrow in Figure 10 shows the direction of water flow in the interface. The flow of water flows from one end of the interface (left end in Figure 10) to the other end of the interface (right end in Figure 10). By setting a check valve to prevent water flow along the direction of water flow The opposite direction flows out.

The interface for mounting the check valve is integrally formed, for example, by an injection molding process. The interface 25 includes a cavity 110 and a limiting portion 120.

In the present embodiment, the cavity 110 is cylindrical, which is formed inside the interface 25, and the check valve 200 and the joint 300 are inserted into the cavity 110 from one end of the cavity 110, and the outer contours of the valve 200 and the joint 300 are checked. Matches the inner contour of the cavity 110.

The limiting portion 120 is located in the cavity 110, and the check valve 200 is inserted into the cavity 110 to be abutted by the limiting portion 120.

Since the interface is integrally formed, the interface structure has a plasticity characteristic, and the interface can be designed to have an integral cavity matching the contour of the check valve, so that the check valve can be directly inserted into the interface, that is, the check valve can be directly installed. In the waterway system, there is no need to additionally install a similar connection structure such as a bushing, and therefore, the related art must be passed through the casing. The installation of the check valve causes the water system to be miniaturized and the possibility of water leakage is large; the miniaturization of the interface portion is realized, space is saved, the connection point is reduced, the possibility of water leakage is reduced; and the interface also has The utility model is used for abutting the check valve to prevent the check valve from being detached from the cavity, thereby facilitating the installation and positioning of the check valve.
