As shown in fig. 1 to 3, fig. 1 is a schematic view of a water outlet device according to an embodiment of the present invention from one viewing angle. Fig. 2 shows an exploded view of spray bar 10 and spray head 20. Fig. 3 is an exploded view of the water outlet device according to the embodiment of the present invention.

The water outlet device comprises a spray rod 10 and a spray head 20, wherein the spray head 20 is arranged at one end of the spray rod 10, and the other end of the spray rod 10 can be connected with a water supply pipe. The water supply pipe is capable of providing a flow of water into spray bar 10. When the user finishes using the toilet, the spray head 20 can spray water flow to clean the buttocks and the lower body.

It should be noted that, the water outlet device of the embodiment of the present invention may be applied to an intelligent toilet, but is not limited thereto. For example, the present invention may be applied to shower heads in bathrooms, car washing spray guns, kitchen faucets or other suitable use scenarios, but the present invention is not limited thereto. For convenience of explanation, the water outlet device is applied to the intelligent toilet as an example.

Referring to fig. 3 and 4, fig. 4 is a sectional view of a first mixing chamber 120 according to an embodiment of the present invention. Spray bar 10 includes first casing 110, first hybrid chamber 120 and screen 130, and first hybrid chamber 120 sets up in first casing 110, and includes first passageway 121 and rectification portion 122 that sets up on first passageway 121, and a plurality of rectification holes 1221 have been seted up on rectification portion 122, and rectification hole 1221 is linked together with first passageway 121 to make when the aqueous vapor mixed liquid that is supplied by the feed pipe passes through rectification portion 122, is divided by rectification portion 122. The screen 130 is disposed on the first channel 121 and downstream of the rectifying portion 122 to slow down the flow rate of the water-gas mixture.

The water-gas mixture supplied from the water supply pipe enters the first passage 121 and is divided into a plurality of parts by the rectifying holes 1221 of the rectifying portion 122. Therefore, water and gas in the water-gas mixed liquor can be better fused. Then, the water-gas mixture rectified by the rectifying part 122 passes through the screen 130. Since the screen 130 has a plurality of screen holes, the water flow speed is reduced after the water-gas mixture passes through the screen 130. According to bernoulli's theorem, when the fluid velocity is decreased, the pressure in the fluid is increased, and the solubility of the gas in water is increased, so that the oxygen content in water can be further increased. In other words, the oxygen content in the water is significantly increased by the combined action of the rectifying portion 122 and the mesh 130.

It is understood that the number of the first passages 121 in the embodiment of the present invention is one or more. In this embodiment, the first mixing chamber 120 includes two independently disposed first channels 121, and each of the first channels 121 has a flow straightener 122 and a screen 130 disposed thereon. When the water-gas mixture passes through the two first passages 121, the water flow having a high oxygen content can be formed by the rectifying portion 122 and the mesh 130.

The mesh sizes of the two screens 130 may be different. Thus, when the water flows through the screens 130 with different mesh numbers, the two screens 130 have different decelerating effects on the water flow, so as to form water flows with different oxygen contents, and finally, the water flows in different states are sprayed by the spray head 20.

As shown in fig. 5 and 6, fig. 5 is a schematic view of a water outlet device according to an embodiment of the present invention from another viewing angle. Fig. 6 shows a cross-sectional view a-a in fig. 5. Spray bar 10 also includes a second mixing chamber 140, with second mixing chamber 140 disposed within first housing 110 and interfacing with first mixing chamber 120. The second mixing chamber 140 includes a second passage 141, and the second passage 141 communicates with the first passage 121. The screen 130 is sandwiched between the first mixing chamber 120 and the second mixing chamber 140. The water flow slowed down by the screen 130 can enter the second channel 141 and finally reach the spray head 20.

It is understood that the number of the second channels 141 may be one or more, and corresponds to the number of the first channels 121. Meanwhile, the one or more second passages 141 are in corresponding communication with the one or more first passages 121 in position.

As shown in fig. 4 and 6, the inner wall of the first channel 121 is provided with a receiving groove 123, and the screen 130 is embedded in the receiving groove 123 and abutted by the end surface of the second mixing chamber 140. That is, the screen 130 is interposed between the bottom wall of the accommodating groove 123 and the end surface of the second mixing chamber 140. By such a design, the screen 130 can be firmly disposed between the first mixing chamber 120 and the second mixing chamber 140, and misalignment of the screen 130 due to water current impact can be prevented.

As shown in fig. 4, 6 and 7, fig. 7 is a cross-sectional view B-B of fig. 5. The spray head 20 includes a second housing 210, a water outlet 220, a micro bubble generator 230, and an end cap 240.

The second housing 210 is connected to the first housing 110 to form an outer shell of the water outlet device.

The water outlet body 220 is disposed in the second housing 210 and includes a third channel 221 and a containing cavity 222, the micro-bubble generator 230 is disposed in the containing cavity 222, and the first channel 121, the second channel 141, the third channel 221 and the containing cavity 222 are communicated.

It is understood that the number of the third channels 221 may be one or more, and corresponds to the number of the second channels 141. Meanwhile, the one or more third channels 221 are in corresponding communication with the one or more second channels 141 in position.

The second housing 210 includes a first outlet hole 211, the outlet body 220 includes a second outlet hole 223, and the second outlet hole 223 is communicated with the accommodating cavity 222 and corresponds to the first outlet hole 211.

The water flows into the microbubble generator 230 after passing through the first, second, and third passages 121, 141, and 221 in sequence. Under the action of the micro-bubble generator 230, a large amount of bubbles are separated out from the water flow to form micro-bubble water, and the micro-bubble water is sprayed out after sequentially passing through the second water outlet 223 and the first water outlet 211, so that the cleaning purpose is realized. Because the oxygen content in the water flow is obviously improved under the action of the rectifying part 122 and the screen 130 before passing through the micro-bubble generator 230, the water flow sprayed out after passing through the micro-bubble generator 230 is rich in micro-bubbles, so that the micro-bubble water sprayed out of the water outlet device disclosed by the embodiment of the utility model has stronger decontamination capability, permeability and deoiling capability, has a better disintegration and cleaning effect on residues on the buttocks of a human body, has a cleaning and bacteriostasis effect on nursing in the menstrual period of a female, and can prevent partial gynecological diseases. In addition, the water flow contains a large amount of oxygen, so that the water flow also has a certain relieving effect on symptoms such as skin itch of a human body.

As shown in fig. 7 and 8, fig. 8 is a sectional view of the microbubble generator 230 according to the embodiment of the present invention. The microbubble generator 230 includes a venturi structure 234, and the venturi structure 234 communicates with the first passage 121, the second passage 141, and the third passage 221. The venturi structure 234 includes an inlet section 231, a throat section 232, and a diffuser section 233, the throat section 232 being disposed between the inlet section 231 and the diffuser section 233. The diameter of the inlet section 231 is gradually smaller and the diameter of the diffuser section 233 is gradually larger along the water flow direction.

When the water flows through the venturi structure 234, the sectional area of the inlet 231 is gradually reduced and the sectional area of the diffuser 233 is gradually increased, and the sectional area is reduced and the water flow speed is increased according to bernoulli's theorem, so that the water pressure is reduced. When the water flow passes through the diffuser 233, the pressure is further released and the solubility of the gas in the water is drastically reduced, so that a large number of micro bubbles are precipitated in the water, and finally micro bubble water is formed.

It is understood that the number of the microbubble generators 230 may be one or more, and the venturi structures 234 of one or more microbubble generators 230 are respectively in communication with one or more third channels 221.

The end cap 240 is connected to the water outlet body 220 to enclose the microbubble generator 230 within the accommodation chamber 222. Meanwhile, a water diversion chamber 260 is formed between the cover 240 and the microbubble generator 230. The water diversion chamber 260 is in communication with the venturi structure 234.

A water-air mixing chamber 250 is formed between the micro-bubble generator 230 and the inner wall surface of the accommodating chamber 222, the venturi structure 234 is communicated with the water-air mixing chamber 250, and the water-air mixing chamber 250 is arranged at the tail end of the venturi structure 234.

As shown in FIG. 8, the length L of throat section 232 is equal to the diameter D1 of throat section 232 along the direction of water flow. The ratio of the diameter D1 of the throat section 232 to the maximum diameter D2 of the inlet section 231 is 1/4-1/3. Through such design, the microbubble effect that produces is better when making rivers pass through throat section 232.

As shown in fig. 3, the second housing 210 is provided with a plurality of first outlet holes 211, and the plurality of first outlet holes 211 can be divided into two groups and are respectively disposed in different areas of the second housing 210. The two sets of first outlet holes 211 are respectively communicated with the two first channels 121.

As mentioned above, the mesh sizes of the screens 130 in the two first channels 121 are different, so that the water-air mixture can pass through the two first channels 121 and the microbubble generator 230, and then two groups of the first water outlet holes 211 can spray out two different states of microbubble water to meet different cleaning requirements, such as hip washing and gynecological washing. It will be appreciated that the number of first outlet holes 211 in each group may be one or more.
