Description

TECHNICAL FIELD

[0001] The utility model relates to water treatment device technical field, concretely relates to a kind of jet device and multiway valve. BACKGROUND

[0002] With the rapid development of China's economy, people's demand for water is increasing, and the hardness of tap water (i.e. calcium and magnesium ion concentration) is high, which has problems such as easy scaling, poor experience of washing face and bathing. As an important water treatment equipment, softener can effectively remove calcium and magnesium ions in water through ion exchange technology, thereby reducing water hardness and improving water quality taste and feel.

[0003] The working process of existing household softener mainly includes softening process and regeneration process. In the softening process, the resin exchange tank inside the softener is filled with cation resin. When hard water containing calcium and magnesium ions passes through the resin exchange tank, the sodium ions (or other functional ions) on the resin will exchange with the calcium and magnesium ions in the water. Most of the calcium and magnesium ions are adsorbed by the resin to make the water flow out with lower concentration of calcium and magnesium ions, thereby achieving water softening. In the regeneration process, when the calcium and magnesium ions adsorbed on the surface of the resin reach saturation state, its exchange capacity will decrease. At this time, reverse flow regeneration technology is needed to use salt water to flush the resin and replace the calcium and magnesium ions on the resin to restore the exchange capacity of the resin. Salt absorption regeneration process of softener usually needs to use a jet device. The jet device can mix salt solution in the salt supply device with raw water to form regeneration liquid, which enters the resin tank to replace the hardness ions in the resin, thereby completing the regeneration process. However, in related technology, the concentrated salt water and raw water entering the jet device are not fully mixed before being ejected by the jet device into the resin tank, which affects the regeneration effect and further affects the softening effect of the softener, resulting in poor user experience.

[0051] Figure 1 A partial cross-sectional structure schematic diagram of the fluidic device provided by the present embodiment is shown. As shown in the figure, Figure 1As shown, the embodiment provides a jet device, which comprises a jet device body 100, a jet channel is formed in the jet device body 100, and a raw water inlet 111 and a salt liquid inlet 112 are arranged on the jet device body 100 and communicate with the jet channel. A water blocking part 131 is arranged in the jet channel, and a gap exists between the water blocking part 131 and the inner wall of the jet channel. The water blocking part 131 is located downstream of the raw water inlet 111 and the salt liquid inlet 112 along the flow direction of the raw water. The raw water flowing into the jet channel through the raw water inlet 111 and the salt liquid flowing into the jet channel through the salt liquid inlet 112 can flow to the outlet of the jet channel from the gap between the water blocking part 131 and the inner wall of the jet channel after impacting the water blocking part 131.

Figure 3 A sectional structural schematic diagram of the shell 110 provided by the embodiment is shown. Figure 4 A sectional structural schematic diagram of the generator 120 provided by the embodiment is shown. Figure 5 A structural schematic diagram of the water blocking part 130 provided by the embodiment is shown from one perspective. Figure 6 A structural schematic diagram of the water blocking part 130 provided by the embodiment is shown from another perspective. Figures 2-6 And in combination with Figure 1As shown, the jet flow device body 100 comprises an outer shell 110, a generator 120 and a water blocking member 130. The outer shell 110 is a hollow structure, and one end of the outer shell 110 is provided with a first mounting port 113 which is in communication with a hollow cavity 1101 in the outer shell 110. A raw water inlet 111 and a salt liquid inlet 112 are both arranged on the outer shell 110. The generator 120 is arranged in the hollow cavity 1101. The generator 120 is provided with a raw water inlet flow channel 121, a water cavity 122 and a mixed liquid inlet flow channel 123 which are sequentially communicated in the direction of the flow of the raw water in the generator 120. The salt liquid inlet 112 is in communication with the water cavity 122. The water blocking member 130 is mounted on the first mounting port 113 and partially extends into the hollow cavity 1101. An end of the water blocking member 130 extending into the hollow cavity 1101 is provided with a water blocking portion 131. A mixed liquid outlet flow channel is further arranged on the water blocking member 130. The raw water inlet 111, the raw water inlet flow channel 121, the water cavity 122, the mixed liquid inlet flow channel 123 and the mixed liquid outlet flow channel are sequentially communicated to form the jet flow channel. By arranging the jet flow device body 100 as the outer shell 110, the generator 120 and the water blocking member 130 which are separate from each other, the processing convenience can be improved.

[0054] As shown in Figure 3 , Figure 5 and Figure 6 , the water blocking member 130 comprises a mounting portion 132 and at least two connecting brackets 133. The mounting portion 132 is inserted into the first mounting port 113 and is provided with a through hole 1321 along the axial direction of the mounting portion 132. The at least two connecting brackets 133 are arranged on the mounting portion 132 along the circumference of the through hole 1321 and extend into the hollow cavity 1101 of the outer shell 110. The water blocking portion 131 is connected to an end of the connecting bracket 133 away from the mounting portion 132. The gap between the at least two connecting brackets 133 is in communication with the through hole 1321 to form the mixed liquid outlet flow channel. By arranging the connecting bracket 133, the stable installation of the water blocking portion 131 can be realized. The disturbance to the raw water and the salt liquid can be realized without affecting the flow of the raw water and the salt liquid, so that the raw water and the salt liquid can be fully mixed.

[0055] In the present embodiment, the number of the connecting brackets 133 is four. The four connecting brackets 133 are uniformly arranged around the through hole 1321 to jointly support the water blocking portion 131. Of course, in other embodiments, the number of the connecting brackets 133 can also be three, five, six or even more, which is not limited herein.

[0056] In order to realize the fixation of the water blocking member 130 and the outer shell 110, a clamping protrusion 1331 is arranged on the connecting bracket 133. A clamping groove (not shown in the figure) which is in clamping cooperation with the clamping protrusion 1331 is arranged on the cavity wall of the hollow cavity 1101 of the outer shell 110.

[0057] As shown in Figure 1 and Figure 5As shown, a first limiting step 1102 is arranged on the cavity wall of the hollow cavity 1101 of the shell 110, and the end face of the mounting portion 132 abuts against the first limiting step 1102, so as to limit the mounting position of the water blocking piece 130, thereby making the water blocking portion 131 have an optimal interval from the generator 120, and ensuring the impact effect of raw water and salt solution on the water blocking portion 131.

[0058] Figure 7 As shown in the structural schematic diagram of the generator 120 provided in the embodiment, Figure 7 and in combination with Figure 1 , Figure 4 As shown, the raw water inlet flow channel 121 comprises a jetting section 1211 and a throat section 1212 which are sequentially communicated, the inlet of the jetting section 1211 is communicated with the raw water inlet 111, the outlet of the throat section 1212 is communicated with the water cavity 122, and the aperture of the throat section 1212 is smaller than that of the jetting section 1211. In this way, the flow rate of the raw water is suddenly increased when passing through the throat section 1212, thereby generating a negative pressure at the water cavity 122, and the salt solution can be sucked into the water cavity 122 from the salt solution inlet 112 under the action of the negative pressure, and then the raw water and the salt solution are mixed in the mixed liquid inlet flow channel 123. In the embodiment, the water cavity 122 is a notch arranged on the side wall of the generator 120, so as to ensure the flow area of the salt solution and mix the raw water and the salt solution in an optimal proportion.

[0059] Optionally, the aperture of the jetting section 1211 gradually decreases along the flow direction of the raw water, so as to provide a guide for the flow of the raw water in the jetting section 1211, and make the raw water flow smoothly into the throat section 1212. In the embodiment, the jetting section 1211 is a multi-stage stepped hole, so as to achieve the effect that the aperture of the jetting section 1211 gradually decreases along the flow direction of the raw water.

[0060] As shown in the structural schematic diagram of the generator 120 provided in the embodiment, Figure 1 and Figure 7 As shown, the first and second sealing pieces are arranged between the generator 120 and the shell 110, and are respectively located on the two sides of the water cavity 122, so as to isolate the raw water, the salt solution and the mixed liquid, and avoid water leakage among them. Optionally, the outer wall of the generator 120 is provided with a first mounting groove 124 for mounting the first sealing piece and a second mounting groove 125 for mounting the second sealing piece, so as to stably mount the first and second sealing pieces and avoid falling off or displacement of the first and second sealing pieces during use.

The number of salt liquid inlets 112 is two, and the two salt liquid inlets 112 are arranged along the circumference of the shell 110 to improve the passing efficiency and volume of the salt liquid. Of course, the embodiment does not limit the specific number of raw water inlets 111 and the specific number of salt liquid inlets 112, and the designer can adjust them according to actual needs.

[0062] Figure 9 A structure schematic diagram of the cover 200 provided by the embodiment is shown. Figure 10 A structure schematic diagram of the cover 200 provided by the embodiment is shown. Figures 9-10 And in combination with Figure 1 , Figure 3 As shown, the fluidic device further comprises a cover 200 and a filter 300. The shell 110 further comprises a second mounting port 114 which is in communication with the hollow cavity 1101 and is arranged at one end of the shell 110 away from the first mounting port 113. The cover 200 is sealed to the second mounting port 114. The filter 300 is arranged in the hollow cavity 1101 and is located between the cover 200 and the generator 120. That is, the shell 110 is a hollow cavity structure with two open ends, one of which forms the first mounting port 113, and the other of which forms the second mounting port 114. The raw water inlet 111 and the salt liquid inlet 112 are arranged on the side wall of the shell 110. By arranging the filter 300, the raw water flowing into the hollow cavity 1101 from the raw water inlet 111 can be filtered to avoid impurities in the raw water from blocking the throat section 1212 with a smaller aperture, thereby ensuring that the entire fluidic device can be used normally. By arranging the cover 200, on the one hand, the cover 200 can facilitate the disassembly and replacement of the filter 300, and on the other hand, the cover 200 can also limit the installation of the filter 300. Optionally, the cover 200 is threadedly connected to the second mounting port 114, which is tightly connected and facilitates disassembly and assembly.

[0063] As shown in Figure 1 , Figure 4 and Figure 10 , the cavity wall of the raw water inlet flow channel 121 of the generator 120 is further provided with a second limiting step 1201, and one end of the cover 200 facing the hollow cavity 1101 of the shell 110 is provided with a limiting groove 202. One end of the filter 300 abuts against the second limiting step 1201, and the other end is limited to be installed in the limiting groove 202, thereby realizing stable installation of the filter 300.

[0064] Optionally, the end of the cover 200 away from the filter 300 is outwardly provided with a handle 201. When installing the fluidic device, the operator can hold the handle 201 to install it on the valve shell of the multi-way valve, thereby increasing the convenience of installation of the fluidic device.

[0065] Continuing as shown in Figure 1 and Figure 2 The embodiment also provides a multi-way valve applied to a soft water device. The multi-way valve comprises a valve body and the above-mentioned injector. The valve body has a mounting channel, and the injector is inserted into the mounting channel. The opening of the mounting channel is blocked by a fixing cap 400. By inserting the injector into the mounting channel of the valve body, the assembly process of the injector can be simplified, the assembly efficiency is improved, and the step of machining a threaded structure on the outer wall of the shell 110 of the injector can be omitted, thereby improving the machining efficiency. By arranging the fixing cap 400, the stable installation of the injector can be realized, and the displacement of the injector during use is avoided, thereby affecting the regeneration effect. In the embodiment, the fixing cap 400 is threadedly connected to the opening of the mounting channel, and the fixing cap 400 is convenient to disassemble and connect tightly. Of course, in other embodiments, the fixing cap 400 can also be connected to the valve body in other ways, which is not limited herein.

[0066] As shown in Figure 8 The third sealing member is located between the raw water inlet 111 and the brine inlet 112, and the fourth sealing member is located downstream of the brine inlet 112, so as to isolate the raw water, the brine and the mixed liquid, and avoid water leakage between the three. Optionally, the outer wall of the shell 110 is provided with a third mounting groove 115 for mounting the third sealing member and a fourth mounting groove 116 for mounting the fourth sealing member, so as to realize the stable installation of the third sealing member and the fourth sealing member, and avoid the falling or displacement of the third sealing member and the fourth sealing member during use.
