The water retaining rib plays a role in slowing down water flow, impact of water flow on the rear wall of the downstream end of the liquid inlet channel is reduced, the rear end of the liquid inlet channel, namely the overflow amount of the downstream end is effectively reduced, correspondingly, the overflow amount of the upstream end of the liquid inlet channel can be increased, the downstream overflow amount of the liquid inlet channel cannot be obviously larger than the upstream overflow amount, and further the water outlet uniformity of a liquid outlet is favorably improved.

Further preferably, the height of the water retaining rib is increased one by one along the water flow direction of the liquid inlet channel. Therefore, the water retaining rib can effectively resist the impact of water flow for many times, and is favorable for improving the water outlet uniformity of the liquid outlet.

Further preferably, the distance between the water retaining ribs is gradually reduced along the water flow direction of the liquid inlet channel. Therefore, the overflow quantity at the downstream of the liquid inlet channel can be further reduced, correspondingly, the overflow quantity at the upstream of the liquid inlet channel can be increased, so that the downstream overflow quantity of the liquid inlet channel can not be obviously larger than the upstream overflow quantity, and the uniformity of water outlet of the liquid outlet can be improved.

Further preferably, the water retaining ribs are located at the middle downstream position of the liquid inlet channel. Therefore, after the water is retained by the water retaining ribs, the downstream overflow amount in the liquid inlet channel is reduced, and the upstream overflow amount of the liquid inlet channel is increased, so that the downstream overflow amount of the liquid inlet channel is not obviously greater than the upstream overflow amount, and the water outlet uniformity of the liquid outlet is improved.

In order to avoid the inlet inflow water when through the urgency, a large amount of water overflows from the upstream end of inlet channel, the position that the inside wall of inlet channel corresponds the inlet has the breakwater of upwards extending. Therefore, the water baffle can block the water flow flowing into the liquid inlet.

Preferably, the upper partition board is provided with a boss extending to the side of the liquid outlet corresponding to the downstream end of the liquid inlet channel, and the boss is provided with a water leakage hole. Like this, behind the direct lateral wall of rushing to the inlet channel of water, the water that spills over can be through leaking the hole and flow downwards, can prevent that water from directly spilling over to the liquid outlet, is favorable to improving the equal liquid effect.

In order to avoid the situation that the water flow is small, the water overflowing from the upper partition plate directly flows into the liquid outlet, and the vertical projections of the upper partition plate and the liquid outlet on the horizontal plane have no overlapping part.

In order to further improve the water outlet uniformity of the liquid outlets, the liquid outlets are uniformly distributed along the length direction of the water outlet platform at intervals.

Further preferably, the liquid outlet is provided with a flow guide part at the bottom of the water outlet platform. Through setting up water conservancy diversion portion, can make the water that the liquid outlet flows out along the internal face of water conservancy diversion portion, avoid direct flow down.

After setting up down the baffle, lower baffle top has formed the cavity that the water supply flow flowed through, under the great condition of velocity of water flow, the water that spills over from inlet channel can flow into the cavity of baffle top down earlier, and the cavity of supreme baffle below is flowed into in the reverse direction again, flows through the liquid outlet at last, and like this, rivers are after circuitous flow many times, can slow down the velocity of flow of liquid outlet to improve out the water homogeneity.

Further preferably, the vertical projections of the lower partition plate and the liquid outlet on the horizontal plane have an overlapping part. Therefore, water flowing into the cavity above the upper partition plate can be prevented from directly flowing downwards from the liquid outlet.

Further preferably, vertical projections of the lower partition plate and the upper partition plate on a horizontal plane have no overlapping part. Because the liquid distributor is usually small in size, if the lower partition plate extends inwards excessively, the sectional area of the water outlet channel is reduced, the water outlet effect is affected, and even the water outlet is difficult.

In order to facilitate installation and positioning, the bottom of the upper cover plate is provided with a positioning block which extends outwards and is used for positioning the installation of the liquid distributor.

Compared with the prior art, the utility model has the advantages that: this liquid distributor is through the inlet channel internally mounted who is at the casing and keeps off water spare, the water that flows in from the inlet flows the in-process along inlet channel, because the existence of fender water spare, can avoid the phenomenon that the overwhelming majority of water in the inlet channel spills over from inlet channel low reaches end, thereby make inlet channel's water spill over from the last baffle relatively evenly, the overflow volume that makes inlet channel low reaches end is a bit bigger than the overflow volume of upper reaches end, and then the liquid outlet that passes through the lower side of the last baffle flows, improves the homogeneity of going out water.

Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 5, the liquid distributor of the present embodiment includes a casing 1 and a cover plate 2, both the casing 1 and the cover plate 2 are in a long shape, wherein the casing 1 is a lower casing, the cover plate 2 is an upper cover plate, both the outer side and the two ends of the casing 1 are provided with mounting posts 19, the corresponding positions of the cover plate 2 are provided with mounting lugs 24, during installation, the cover plate 2 covers the casing 1, and screws penetrate through the mounting lugs 24 and are connected and fixed on the corresponding mounting posts 19, so that the cover plate 2 is detachably assembled on the casing 1. After the installation, the cover plate 2 and the shell 1 enclose a liquid distribution cavity 3 together. In this embodiment, the housing 1, i.e. the lower housing, is provided with a liquid inlet 11 and a liquid outlet 12, and the liquid inlet 11 is communicated with the liquid outlet 12 through the liquid distribution cavity 3.

In this embodiment, the liquid inlet channel 13 is disposed on the outer side of the housing 1, i.e., the lower housing, the liquid inlet channel 13 is disposed along the length direction of the housing 1, the liquid inlet channel 13 is a component of the liquid distribution chamber 3, and the liquid inlet 11 is directly communicated with the liquid inlet channel 13. The liquid inlet 11 of this embodiment has 1 and is arranged at the end of the housing 1, and the liquid inlet 11 is communicated with the upstream end of the liquid inlet channel 13, and the liquid inlet direction is perpendicular to the water flow direction inside the liquid inlet channel 13. The inner side wall 131 at the upstream end of the liquid inlet channel 13 is provided with the water baffle 16 extending upwards, and after the water baffle 16 is arranged, the phenomenon that the upstream end of the liquid inlet channel 13 overflows by using a large amount of water due to the fact that water rushes out of the upstream end of the liquid inlet channel 13 when the water in the liquid inlet 11 flows through the liquid inlet channel urgently can be avoided.

Referring to fig. 3 and 6, the direction of the water flow in the inlet channel 13 is shown by the arrow a in fig. 3, and a water blocking member is installed inside the inlet channel 13, and the water blocking member is used for blocking the liquid flowing in from the inlet 11 from directly rushing to the rear wall 132 at the downstream end of the inlet channel 13. The water blocking piece of this embodiment adopts the water blocking muscle 14 of arranging along the rivers direction interval of inlet channel 13, and water blocking muscle 14 is located inlet channel 13's well low reaches, and the water blocking muscle 14 highly increases one by one along inlet channel 13's rivers direction to, the interval of water blocking muscle 14 diminishes gradually along inlet channel 13's rivers direction.

The structure of the water retaining rib 14 is arranged in the liquid inlet channel 13, and in the process that water flow entering the liquid inlet channel 13 from the liquid inlet 11 flows from upstream to downstream, the water flow firstly touches the water retaining rib 14 near the midstream of the liquid inlet channel 13, so that the water flow is prevented from directly rushing to the rear wall 132 of the downstream end of the liquid inlet channel 13, and the water flow continuously flows downstream after crossing the water retaining rib 14 at the position because the height of the water retaining rib is lowest; then, the water flow touches the next water blocking rib 14, namely the middle water blocking rib 14 shown in the figure, because the height of the water blocking rib 14 is higher than that of the previous water blocking rib 14, the water blocking rib 14 further blocks the water flow at the position so as to block the water flow from rushing to the rear wall 132 at the downstream end of the liquid inlet channel 13; when the water flow passes through the middle water blocking rib 14 and then continues to flow downstream, the water flow finally touches the water blocking rib 14 close to the downstream end, the height of the water blocking rib 14 is higher than that of the middle water blocking rib 14, the water flow is further blocked, and the water flow is prevented from rapidly rushing to the rear wall 132 of the downstream end of the liquid inlet channel 13.

The water blocking piece is not limited to the water blocking rib 14, and only needs to be started to block water flow, for example, the water blocking piece can adopt a water blocking strip arranged in a spiral shape, can also adopt a water blocking strip which is continuously arranged along the water flow direction and bent back and forth, and can also be improved through the structure of the liquid inlet channel 13 per se so as to slow down the impact of the water flow on the rear wall of the downstream end of the liquid inlet channel 13.

Referring to fig. 3 and 7, the top of the inner sidewall 131 of the liquid inlet channel 13 extends to the direction away from the liquid inlet channel 13 to form an upper partition 15, and the upper partition 15 is strip-shaped. The upper partition 15 is provided with a boss 17 extending in a direction away from the liquid inlet channel 13 at a position corresponding to the downstream end of the liquid inlet channel 13, and the boss 17 is provided with a water leakage hole 171. The lower part of the inner side wall 131 of the liquid inlet channel 13 extends to the direction far away from the liquid inlet channel 13 to form a water outlet platform 18, the water outlet platform 18 is in a strip shape, and the water outlet platform is positioned below the upper partition 15 and the boss 17 and is parallel to the upper partition 15 and the boss 17. The liquid outlet 12 is disposed on the water outlet platform 17, and a flow guiding portion 121 is formed at the bottom of the water outlet platform 18 of the liquid outlet 12, as shown in fig. 2. In addition, the liquid outlets 12 are distributed at intervals along the length direction of the water platform 18, and in order to improve the uniformity of the discharged water, in this embodiment, the liquid outlets 12 are distributed at intervals along the length direction of the water platform 18. As shown in fig. 7, the vertical projections of the upper partition 15 and the liquid outlet 12 on the horizontal plane have no overlapping portion, that is, the liquid outlet 12 is located obliquely below the upper partition 15, so that it can be seen that the liquid inlet channel 13 and the liquid outlet 12 are respectively located at two sides of the upper partition 15.

As shown in fig. 5 and 7, the cover plate 2 has a lower partition 21 extending inward into the liquid distribution chamber 3, and the lower partition 21 is located above the water outlet platform 18 and parallel to the water outlet platform 18. The vertical projection of the lower partition plate 21 and the liquid outlet 12 on the horizontal plane has an overlapping part, and in this embodiment, the orthographic projection surface of the lower partition plate 21 on the water outlet platform 18 completely covers the liquid outlet 12. And, the vertical projection of the lower partition 21 and the upper partition 15 on the horizontal plane has no overlapping part, so that a water flow channel is formed between the lower partition 21 and the inner side wall 131 of the liquid inlet channel 13.

As can be seen from the water flow direction shown by the arrow in fig. 7, after the water flowing into the liquid inlet channel 13 from the liquid inlet 11 overflows from the upper partition 15 inside the liquid inlet channel 13, at this time, the water pressure is relatively large, the water overflowing from the upper partition 15 does not directly flow into the lower liquid distribution cavity 32 below the upper partition 15, but first flows into the upper liquid distribution cavity 31, the water entering the upper liquid distribution cavity 31 flows onto the cover plate inner side wall 26, returns back to the lower partition 21, then flows into the lower liquid distribution cavity 32 after flowing through the lower partition 21, and finally flows out from the liquid outlet 12. Therefore, the water overflowing from the liquid inlet channel 13 flows through collision and multiple roundabouts, the pressure of the water is released, the water outlet speed of the liquid outlet 12 can be slowed down, the overflow amount of the downstream end of the liquid inlet channel 13 is avoided, and the phenomenon that the water overflows at the upstream end of the liquid inlet channel 13 is avoided, so that the water outlet uniformity of the liquid outlet 12 is relatively improved, the overflow amount of the downstream end of the liquid inlet channel 13 is slightly larger than that of the upstream end, and the water outlet requirement of the liquid distributor is met.

The bottom of the cover plate 2 of this embodiment has positioning blocks 22 extending outward, the positioning blocks 22 are distributed at intervals along the length direction of the cover plate 2, and the positioning blocks 22 correspond to the liquid outlets 12 one by one. The bottom of the cover plate 2 is provided with a supporting block 23 extending inwards, and after the cover plate 2 is installed on the shell 1, the supporting block 23 is supported on the water outlet platform 18 of the shell 1 to play a role in preventing loosening.
