The water softener has a water supply state, a regeneration state and a water supplementing state. When the water softener is in a water supply state, raw water flows to the multi-way valve 20 through the bypass valve 30 and the ejector 10 and enters the resin tank, and hardness ions (calcium ions, magnesium ions and the like) in the raw water are adsorbed by the resin in the resin tank, so that the raw water is softened; when the water softener is in a regeneration state, raw water and salt solution in the salt supply device are mixed to form regeneration solution, and the regeneration solution enters the resin tank through the multi-way valve 20 of the water softener to perform a regeneration reaction on resin in the resin tank, so that sufficient regenerated ions in the resin tank are ensured; when the salt solution in the salt supply device is used for a period of time, the salt solution in the salt supply device needs to be replenished, and the water softener is in a water replenishing state and needs to be supplied with raw water to enter the salt supply device, so that more salt in the salt supply device is dissolved, and more salt solution is formed for use.

The regeneration liquid enters a resin tank to carry out a regeneration reaction with resin, and the principle is as follows: the hardness ions (calcium ions, magnesium ions, etc.) adsorbed by the resin are replaced with ions (sodium ions) that exert a regenerating effect in the regenerating liquid. The sodium ions in the sucked regeneration liquid can exchange with the ineffective resin particles to restore the partial softening capability of the resin, and the exchanged solution containing calcium and magnesium ions is rapidly discharged under the pushing of gas, so that the regeneration is realized.

Referring to fig. 1, in an embodiment, a water softener ejector 10 is respectively connected to a salt supply device of the water softener, a multi-way valve 20 of the water softener, and a bypass valve 30 of the water softener, and the bypass valve 30 is connected to a water supply device for supplying raw water. The ejector 10 is positioned between the bypass valve 30 and the multi-way valve 20, and the ejector 10 can guide liquid to flow from the salt supply device or the bypass valve 30 to the multi-way valve 20 and enter a resin tank of the water softener through the multi-way valve 20; in addition, the ejector 10 is also capable of directing the flow of liquid from the multi-way valve 20 to the salt feeding device to replenish the salt feeding device with water. As for the composition of the liquid guided by the ejector 10, it is selected according to the state in which the water softener is located.

Specifically, referring to fig. 2, the bypass valve 30 has a first connection port 31, and the multiway valve 20 has a second connection port 21, and the second connection port 21 is different from the first connection port 31 in height. The ejector 10 includes a main body 100, the main body 100 having a flow passage 101 for conducting the bypass valve 30 and the multiple-way valve 20, the flow passage 101 having a first opening end 101a and a second opening end 101b having different height positions, the second connection port 21 being connected to the second opening end 101b, and the first connection port 31 being connected to the first opening end 101a.

Here, the height direction is the Y direction shown in fig. 2, and the flow channel 101 is normally open and is used to communicate the first connection port 31 and the second connection port 21 of the multiway valve 20. For example, when the water softener is in a water supply state, raw water flows into the resin tank through the first connection port 31, the flow passage 101, and the second connection port 21 in this order, is softened, flows to the multi-way valve 20, the flow passage 101, and the bypass valve 30, and the softened soft water is output from the bypass valve 30.

The ejector 10 has different height positions of the first connection port 31 of the bypass valve 30 and the second connection port 21 of the multiway valve 20, and the through-flow channel 101 of the ejector 10 has different height positions of the open ends, so as to be respectively connected with the first connection port 31 of the bypass valve 30 and the second connection port 21 of the multiway valve 20, thereby effectively solving the problem of dislocation butt joint of the bypass valve 30 and the multiway valve 20.

It should be noted that, in the above embodiment, referring to fig. 2, the main body 100 further has a fluidic channel separately provided from the flow channel 101, and the fluidic channel may selectively communicate with the multiway valve 20.

For example, when the water softener is in a water supply state, the jet channel and the multi-way valve 20 are in a blocking state, raw water flows into the resin tank through the bypass valve 30, the through-flow channel 101 and the multi-way valve 20 in sequence for softening treatment, flows into the multi-way valve 20, the through-flow channel 101 and the bypass valve 30, and soft water after softening treatment is output by the bypass valve 30; when the water softener is in a regeneration state, the jet flow channel and the multi-way valve 20 are in a conduction state, raw water sequentially flows through the bypass valve 30, the flow channel 101, the multi-way valve 20 and the jet flow channel to generate regeneration liquid, and the regeneration liquid flows into the resin tank through the multi-way valve 20 so as to achieve the purposes of resin cleaning and ion exchange; when the water softener is in a water supplementing state, the jet flow channel and the multi-way valve 20 are in a conducting state, raw water sequentially flows through the bypass valve 30, the through-flow channel 101, the multi-way valve 20 and the jet flow channel and flows into the salt supply device, so that enough salt solution is stored in the salt supply device.

More specifically, referring to fig. 1, the flow channel 101 is Z-shaped or S-shaped.

It can be understood that, in addition to the main body 100, the ejector 10 further includes the jet assembly 200 disposed inside the main body 100, and by making the flow channel 101Z-shaped or S-shaped, the flow channel 101 can have the open ends with different height positions without affecting the layout of the jet assembly 200, so as to smoothly interface with the bypass valve 30 and the multi-way valve 20.

In other embodiments, the flow channel 101 may have a C-shape or other shapes, so long as it has an open end with a different height position to interface with the bypass valve 30 and the multiplex valve 20.

In this embodiment, the body 100 of the ejector 10 has a flow passage 101. In other embodiments, the body 100 of the ejector 10 may further have at least two through-flow channels 101, and all of the through-flow channels 101 may be disposed at intervals side by side in the same direction.

Referring to fig. 2, the main body 100 includes a first cover 110, a second cover 120 and a third cover 130 that are detachably connected, the third cover 130 and the first cover 110 are respectively disposed on opposite sides of the second cover 120, and the through-flow channel 101 is disposed between the first cover 110, the second cover 120 and the third cover 130.

Specifically, referring to fig. 3 and 4, one side of the second cover 120 is buckled with the first cover 110 to form a first cavity, the other side of the second cover 120 is buckled with the third cover 130 to form a second cavity, the second cavity is communicated with the second connection port 21 of the multi-way valve 20, the first cavity is communicated with the first connection port 31 of the bypass valve 30, the first cavity is communicated with the second cavity, and the jet channel is communicated with the second cavity. Thus, the bypass valve 30 and the multi-way valve 20 are respectively arranged on different sides of the ejector 10, so that the bypass valve 30 and the multi-way valve 20 can be prevented from interfering with each other, and the ejector 10 can meet the requirements of integration and miniaturization design.

In the present embodiment, the first cover 110, the second cover 120 and the third cover 130 are all detachably connected, so that the ejector 10 can be quickly disassembled and maintained. For example, the first cover 110 is provided with a first fixing hole, the second cover 120 is provided with a second fixing hole, the third cover 130 is provided with a third fixing hole, and the first fixing hole, the second fixing hole and the third fixing hole are penetrated by the fastening piece 140 to lock the covers, and the fastening piece 140 can be a screw or a bolt. In other embodiments, the first cover 110, the second cover 120 and the third cover 130 may be integrally formed.

Referring to fig. 3 and 4, the second cover 120 includes a fixing portion 121 and a first protruding portion 122 connected to one end of the fixing portion 121, wherein the fixing portion 121 is sandwiched between the first cover 110 and the second cover 120 along a first direction, the first protruding portion 122 is located on an inner side of an inner wall of the first cover 110 along a second direction, and the second direction is perpendicular to the first direction.

Here, the first direction is the X direction shown in fig. 3 and 4, and the second direction is the Y direction (i.e., the height direction) shown in fig. 3 and 4. Through the above arrangement, the fixing portion 121 can seal the first cover 110 and the second cover 120 in the first direction, and the first protruding portion 122 can seal the first cover 110 and the second cover 120 in the second direction, so as to prevent the first cover 110 and the second cover 120 from having gaps and affecting the tightness.

In this embodiment, the fixing portion 121 and the first protruding portion 122 are integrally formed, so that the integrity is good and the mechanical strength is high, which is beneficial to improving the tightness between the cover bodies. In other embodiments, the fixing portion 121 and the first protruding portion 122 may be a split structure.

Referring to fig. 3 and 4, the ejector 10 further includes a sealing member 300, and the sealing member 300 is sandwiched between the first protruding portion 122 and the inner wall of the first cover 110. The longitudinal section of the sealing member 300 is circular and has a diameter d, the distance between the first protruding portion 122 and the inner wall of the first cover 110 is H, and the compression ratio w= (d-H)/d of the sealing member 300.

It is understood that the compression ratio of the sealing member 300 is related to the diameter d of the sealing member 300 and the distance H between the first protrusion 122 and the inner wall of the first cover 110. With the above arrangement, the first cover 110, the second cover 120, and the third cover 130 are assembled and fixed in the first direction, the sealing member 300 receives the lateral compression force in the second direction perpendicular to the first direction, and the problem of water leakage caused by excessive compression deformation of the sealing member 300 can be improved by controlling the compression ratio of the sealing member 300.

Preferably, the seal 300 is a silicone or rubber ring.

Further, referring to fig. 3, the compression ratio of the sealing member 300 ranges from 10% to 30%.

It can be appreciated that if the compression ratio of the sealing member 300 is too high, the sealing member 300 is easily damaged due to the excessive compression force, so that a water leakage problem occurs between the first cover 110 and the second cover 120; if the compression ratio of the seal 300 is too small, the seal 300 is subjected to too small a pressing force, and the seal fails, so that the first cover 110 and the second cover 120 cannot be sealed. By controlling the compression ratio of the sealing member 300 to be in an optimal range, it is ensured that the sealing member 300 is not damaged due to excessive pressing force, and the first and second covers 110 and 120 are effectively sealed.

Still further, referring to FIG. 3, the seal 300 has a hardness of 60-90 degrees.

It can be appreciated that if the hardness of the seal 300 is too high, the seal 300 may have problems such as difficult assembly and excessive stress, for example, poor sealing and dripping problems may occur when the structure is easily deformed or the surface roughness of the sealing surface is large; if the hardness of the seal 300 is too small, the seal 300 may suffer from insufficient side pressure, such as a problem of poor sealing due to a large impact force of the liquid on the seal 300. By controlling the hardness of the seal 300 to be in an optimal range, the seal 300 is ensured to be easy to assemble, and meanwhile, the seal 300 is ensured to have a good sealing effect.

Referring to fig. 3, the number of the sealing members 300 is at least two, and all the sealing members 300 are arranged side by side along the first direction. In this way, the sealing effect between the first cover 110 and the second cover 120 can be enhanced.

In this embodiment, all the sealing members 300 are the same in material and size. In other embodiments, the materials and dimensions of all the sealing members 300 may not be completely the same or completely different, so as to be adjusted according to the actual situation.

Referring to fig. 3, the second cover 120 further includes a second protruding portion 123, the second protruding portion 123 is connected to an end of the fixing portion 121 away from the first protruding portion 122, the second protruding portion 123 is located on an inner side of an inner wall of the third cover 130 in the second direction, and a sealing member 300 is further disposed between the second protruding portion 123 and the inner wall of the third cover 130.

With the above arrangement, the second protrusion 123 is provided to enable the third cover 130 to be sealed with the second cover 120 in the second direction; the third cover 130 and the second cover 120 are assembled and fixed along the first direction, and the sealing member 300 receives a lateral compression force in the second direction perpendicular to the first direction, so that the problem of water leakage caused by excessive compression deformation of the sealing member 300 can be solved.

In the present embodiment, the number of the sealing members 300 between the second protruding portion 123 and the inner wall of the third cover 130 is not limited to one, i.e. there may be at least two sealing members 300 between the second protruding portion 123 and the inner wall of the third cover 130.

Referring to fig. 2 and 5, the first opening end 101a has two first openings arranged at intervals, the first connection port 31 includes a first inlet 31a and a first outlet 31b, and the first inlet 31a and the first outlet 31b are respectively connected with one first opening; the second opening end 101b has two second openings arranged at intervals, the second connection port 21 includes a second inlet 21a and a second outlet 21b, and the second inlet 21a and the second outlet 21b are respectively connected with one second opening. By the arrangement, the bypass valve 30 and the multiway valve 20 can be communicated and butted with the corresponding inlet and outlet through the arrangement of the flow passage 101.

For example, when the water softener is in a water supply state, raw water flows through the first inlet 31a of the bypass valve 30, the through-flow passage 101, and the second inlet 21a of the multi-way valve 20 in this order into the resin tank for softening treatment, flows to the second outlet 21b of the multi-way valve 20, the through-flow passage 101, and the first outlet 31b of the bypass valve 30, and the softened soft water is outputted from the first outlet 31b of the bypass valve 30.

Referring to fig. 1, a water softener according to an embodiment includes the above-described water softener ejector 10.

Specifically, the water softener further comprises a bypass valve 30, a multi-way valve 20, a resin tank and a salt supply device. When the water softener is in a water supply state, raw water enters the resin tank through the bypass valve 30, the ejector 10 and the multi-way valve 20 to soften the raw water; when the water softener is in a regeneration state, the regeneration liquid enters the resin tank through the multi-way valve 20 to regenerate the resin tank; when the water softener is in a water supplementing state, raw water enters the salt supply device through the bypass valve 30 and the ejector 10 to supplement water to the salt supply device.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
