[0048] Embodiment 1

[0049] See also Figures 1 to 5 As shown, this embodiment provides an air intake mechanism, which is applied to a bubble water preparation device. The air intake mechanism includes an air intake chamber 103 and a water intake chamber 102, and the air intake chamber 103 and the water intake chamber 102 are independently arranged.

[0050] Based on this structure, the air intake mechanism provided in this embodiment can adjust the pressure of the air intake chamber 103 and the pressure of the water intake chamber 102 respectively by independently setting the air intake chamber 103 and the water intake chamber 102, thereby facilitating the preliminary mixing of the gas in the air intake chamber 103 and the water in the water intake chamber 102, thereby realizing automatic and continuous provision of bubble water without the need for a booster pump and without consuming electrical energy.

[0051] Further, in some optional embodiments, see Figure 1 and Figure 2 As shown, the air intake mechanism further includes a tube shell 101 , a water intake chamber 102 is located inside the tube shell 101 , and a gap is provided between the outer surface of the chamber wall of the water intake chamber 102 and the inner wall of the tube shell 101 to form an air intake chamber 103 .

[0052] The water inlet chamber 102 has a water source inlet 105 and a water outlet 106 which are arranged opposite to each other. The water source inlet 105 is used to communicate with an external water source, and the water outlet 106 is located below the water source inlet 105 .

[0053] When in use, the water source inlet 105 is connected to an external water source, for example, the water source inlet 105 is connected to the bottom of the tap, the faucet is turned on, and the tap water enters the water inlet chamber 102. When the water flows through the water outlet 106, a pressure difference is generated between the air inlet chamber 103 and the water inlet chamber 102, which has a certain suction force on the air inlet chamber 103, thereby facilitating the preliminary mixing of air and water in the air inlet chamber 103.

[0054] It should be noted that the air inlet chamber 103 and the water inlet chamber 102 may also be placed side by side. In this case, the outlet of the air inlet chamber 103 and the water outlet 106 of the water inlet chamber 102 are connected via a three-way pipe.

[0055] Further, in some optional embodiments, see Figure 2 As shown, the cross-sectional area of ​​the water inlet chamber 102 gradually decreases from the water source inlet 105 to the water outlet 106. This increases the flow rate of the water at the water outlet 106, and is more conducive to generating a pressure difference between the air inlet chamber 103 and the water inlet chamber 102, thereby sucking in the gas in the air inlet chamber 103 and preliminarily mixing it with water.

[0056] Further, in some optional embodiments, a drainage port 107 is provided at the lower end of the tube shell 101, and a gap is provided between the drainage port 107 and the water outlet 106, and the diameter of the drainage port 107 is larger than the diameter of the water outlet 106. When the water flow accelerates from the water source inlet 105 to the water outlet 106, the gap between the drainage port 107 and the water outlet 106 has a certain suction force on the air inlet chamber 103, and the air in the air inlet chamber 103 enters the drainage port 107 and is preliminarily mixed with the water.

[0057] In order to realize automatic and continuous air intake under a relatively large tap water pressure, it is necessary to realize that the air intake chamber 103 is at a negative pressure and the air mixing chamber where water and air are initially mixed is at a positive pressure. Not only the air intake chamber 103 and the air mixing chamber must be effectively isolated, but also the gap s between the drainage port 107 and the water outlet 106 must be small enough. In a possible design of this embodiment, see Figure 3 As shown, the drainage port 107 is located directly below the water outlet 106, and the gap s between the drainage port 107 and the water outlet 106 is no greater than 5 mm.

[0058] Optionally, the gap s between the drainage port 107 and the water outlet 106 may be, but is not limited to, 1 mm, 2 mm, 3 mm, 4 mm or 5 mm.

[0059] In another possible design of this embodiment, the water outlet 106 is located inside the drainage port 107, and the gap s between the drainage port 107 and the water outlet 106 is no greater than 5 mm.

[0060] In this embodiment, a connecting tube is integrally formed at the lower end of the tube shell 101 , and the inner cavity of the connecting tube is the gas mixing cavity 115 .

[0061] Furthermore, in certain optional embodiments, a drainage extension section 108 is extended from the lower end of the tube shell 101 of the air intake mechanism, and the drainage extension section 108 is connected to the drainage port 107. The drainage extension section 108 is used to inject water in the water inlet chamber 102 and gas in the air intake chamber 103 into the mixing chamber 115 for mixing.

[0062] In order to achieve automatic and continuous air intake under a higher tap water pressure, it is necessary to achieve a negative pressure in the air intake chamber 103 and a positive pressure in the air mixing chamber 115, so that the water in the water intake chamber 102 is injected into the air mixing chamber 115 through the drainage extension section 108, and the negative pressure is used to inject the gas in the air intake chamber 103 into the air mixing chamber 115 to achieve preliminary mixing of gas and water.

[0063] When the water outlet 106 is inserted into the drainage extension section 108 , the gap s between the drainage port 107 and the water outlet 106 may be, but is not limited to, 1 mm, 2 mm, 3 mm, 4 mm or 5 mm.

[0064] Furthermore, in some optional embodiments, the drainage extension section 108 is a straight tube section; or the cross-sectional area of ​​the drainage extension section 108 gradually increases from the end where the drainage extension section 108 is connected to the drainage port 107 toward the free end of the drainage extension section 108.

[0065] In one possible design, see Figure 2 As shown, the drainage extension section 108 is a straight pipe section. If the straight pipe section is too short, the separation effect between the air inlet chamber 103 and the air mixing chamber is not obvious; if the straight pipe section is too long, although it can provide a better spatial separation effect, the increased length increases the resistance between water and the tube wall, consumes the water kinetic energy, and affects the flow rate of the fluid flowing out of the drainage extension section 108, resulting in a weakened impact force and affecting the gas-liquid mixing effect.

[0066] Optionally, the length of the straight pipe section in this embodiment is 2 to 5 times the diameter of the drainage port 107 .

[0067] In another possible design, see Figure 4 As shown, the cross-sectional area of ​​the drainage extension section 108 gradually increases from the end where the drainage extension section 108 is connected to the drainage port 107 toward the free end of the drainage extension section 108, that is, the drainage extension section 108 is trumpet-shaped. This makes the water flow divergent at the end of the drainage extension section 108, which can increase the area of ​​gas-liquid mixing.

[0068] Furthermore, in some optional embodiments, the air intake mechanism also includes an air intake pipeline 109 , and the air intake pipeline 109 is connected to the air intake chamber 103 .

[0069] In a possible design of this embodiment, see Figure 2 As shown, the air intake line 109 is located at the top of the air intake chamber 103 .

[0070] Furthermore, in some optional embodiments, the angle between the axis of the air inlet pipeline 109 and the axis of the water inlet chamber 102 is 30° to 60°.

[0071] The air intake pipe 109 in this embodiment is located at the top of the air intake chamber 103 , and the angle between the axis of the air intake pipe 109 and the axis of the water intake chamber 102 is 30° to 60°, which can reduce the resistance of air entering the air intake chamber 103 .

[0072] Optionally, the angle between the axis of the air inlet pipeline 109 and the axis of the water inlet chamber 102 may be, but is not limited to, 30°, 40°, 50° or 60°.

[0073] Preferably, the angle between the axis of the air inlet pipeline 109 and the axis of the water inlet chamber 102 is 40° to 50°.

[0074] In another possible design of this embodiment, see Figure 5 As shown, the air intake pipeline 109 is located at one end of the drainage extension section 108 close to the drainage port 107 .

[0075] Specifically, a gas inlet is provided on the side wall of the drainage extension section 108 at one end close to the jet port. At this time, the air inlet pipeline 109 passes through the tube wall of the tube shell 101 and is connected with the gas inlet on the drainage extension section 108 .

[0076] The axis of the air intake pipe 109 arranged in the drainage extension section 108 needs to form a certain angle with the water flow direction so that the air can smoothly enter the mixing chamber driven by the water flow. In this embodiment, the angle between the axis of the air intake pipe 109 and the water flow direction is 30°~80°.

[0077] Optionally, the angle between the axis of the air inlet pipe 109 and the water flow direction may be, but is not limited to, 30°, 40°, 50°, 60°, 70° or 80°.

[0078] More preferably, the angle between the axis of the air inlet pipe 109 and the water flow direction is 40° to 60°.

[0079] In this embodiment, the air intake pipeline 109 is provided with a one-way valve 104. After the air in the air intake chamber 103 is sucked in, the air intake chamber 103 is under negative pressure, thereby automatically opening the one-way valve 104, and the air outside the air intake chamber 103 is sucked into the air intake chamber 103, realizing automatic and continuous air intake.

[0080] Furthermore, in some optional embodiments, the water inlet chamber 102 is in a hollow cone shape, and the angle between the extension direction of the chamber wall of the water inlet chamber 102 and the axis of the water inlet chamber 102 is 10° to 35°. This method can increase the flow rate of water, so that the water can withstand greater back pressure when flowing out of the water outlet 106.

[0081] If the angle between the extension direction of the chamber wall of the water inlet chamber 102 and the axis of the water inlet chamber 102 is too large, the flow velocity will change rapidly and the kinetic energy of water lost due to friction of the chamber wall will increase; if the angle between the extension direction of the chamber wall of the water inlet chamber 102 and the axis of the water inlet chamber 102 is too small, the water inlet chamber 102 will be too long, the overall size of the device will become larger, and the cost will also increase.

[0082] Preferably, the angle between the extension direction of the chamber wall of the water inlet chamber 102 and the axis of the water inlet chamber 102 is 20° to 30°.

[0083] Furthermore, in some optional embodiments, a chamber wall of the water inlet chamber 102 is provided with a connecting and fixing portion, and the connecting and fixing portion is fixedly connected to the tube shell 101 .

[0084] In this embodiment, the connection fixing portion is fixedly connected to the tube shell 101, so that the air inlet chamber 103 is a closed cavity.

[0085] Further, in some optional embodiments, see Figure 2 As shown, the connecting and fixing part includes a top plate 110 and a side wall 111. The top plate 110 has a through hole connected to the water source inlet 105. The edge of the through hole is fixedly connected to one end of the water inlet chamber 102 close to the water source inlet 105. The edge of the top plate 110 is fixedly connected to the side wall 111. The side wall 111 is fixedly connected to one end of the tube shell 101 close to the water source inlet 105.

[0086] In this embodiment, the top plate 110 and the water inlet chamber 102 are integrally formed.

[0087] Optionally, the top plate 110 is circular in shape, the side wall 111 is an annular side wall, the outer peripheral surface of the side wall 111 is provided with an external thread, and the tube shell 101 is provided with an internal thread matching the external thread.

[0088] Furthermore, in some optional embodiments, the inner surface of the chamber wall of the air inlet chamber 103 has a smooth transition, which can reduce the resistance when the air enters the air inlet chamber 103 and enters the drainage port 107 through the air inlet chamber 103 .

[0089] Embodiment 2

[0090] See also Figure 6 and Figure 7 As shown, this embodiment provides a device for preparing bubble water, including the air intake mechanism provided in the first embodiment of the present disclosure.

[0091] Further, in some optional embodiments, there are multiple air intake mechanisms, and the multiple air intake mechanisms are connected in series or in parallel. In this case, a water inlet manifold needs to be used in conjunction with the water inlet manifold.

[0092] Further, in some optional embodiments, see Figure 7 As shown, the bubble water preparation device further includes a gas mixing tank 112, and the gas mixing tank 112 is fixedly connected to the tube shell 101. The gas and water that have been preliminarily mixed are further fully mixed in the gas mixing tank 112.

[0093] Further, in some optional embodiments, a connecting pipe is integrally formed at the lower end of the tube shell 101 , the connecting pipe is threadedly connected to the upper end of the mixing tank 112 , one end of the connecting pipe is connected to the drainage port 107 , and the other end of the connecting pipe is connected to the mixing tank 112 .

[0094] In this embodiment, a gas-liquid mixer 113 is disposed inside the gas mixing tank 112 , and the drainage port 107 is located directly above the gas-liquid mixer 113 to ensure a good gas mixing effect.

[0095] In this embodiment, the bubble water preparation device further includes a bubble releaser 114 , which is connected to the lower end of the gas mixing tank 112 .

[0096] It should be noted that the bubble releaser 114 and the gas-liquid mixer 113 are both existing technologies, and their structures are not described in detail in this embodiment.

[0097] Embodiment 3

[0098] This embodiment provides a water output device, including the bubble water preparation device provided in the second embodiment of the present disclosure.

[0099] The water outlet device provided in this embodiment, due to the use of the bubble water preparation device provided in the second embodiment of the present disclosure, can not only save electricity and reduce noise, but also meet the demand for long-term use of bubble water, thereby improving the user experience.

[0100] It should be noted that the water outlet device provided in this embodiment may be a drinking water device, a cleaning device, a water heater or a shower head, etc.

[0101] In summary, the present invention can utilize negative pressure to inhale gas and mix it with water flowing out of the water outlet 106, thereby realizing automatic and continuous provision of bubble water without the need for a booster pump and without consuming electrical energy. When in use, the water source inlet 105 is connected to an external water source, for example, the water source inlet 105 is connected to the bottom of the tap, the faucet is turned on, and the tap water enters the water inlet chamber 102. When the water flows through the water outlet 106, since the cross-sectional area of ​​the water inlet chamber 102 gradually decreases from the water source inlet 105 to the water outlet 106, the flow rate of the water at the water outlet 106 increases, and the gap between the drainage port 107 and the water outlet 106 has a certain suction force on the air inlet chamber 103. The air in the air inlet chamber 103 enters the drainage port 107 and is preliminarily mixed with the water. After the air in the air inlet chamber 103 is sucked in, the air inlet chamber 103 is under negative pressure, thereby automatically opening the one-way valve 104, and the air outside the air inlet chamber 103 is sucked into the air inlet chamber 103, realizing automatic and continuous air intake.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
