[0032] Embodiment

[0033] Combined Figures 1 to 4 As shown, the first embodiment of the present invention provides a microbubble functional shower, including a main body 40, a shower head 50 and a microbubble functional shower air dissolving device. Among them, the second opening 35 is connected to the shower head 50 through a hose, and a microbubble generating device is provided on the shower head 50.

[0034] Combined Figure 1 and Figure 2 , the microbubble functional shower air dissolving device described in this embodiment includes: an air inlet device 10, a connection component 20 and an air dissolving component 30. Among them, the air inlet device 10 is used to introduce gas;

[0035] The connecting water passage 41 of the connecting component 20 is connected to the air inlet device 10, which is suitable for the flow of water and gas, and is configured to control the opening and closing of the air inlet device 10 according to the opening and closing of the water passage 41;

[0036] The air dissolving component 30 is provided with an air dissolving cavity 321. The air dissolving cavity 321 is provided with a first opening 34 and a second opening 35. The first opening 34 is connected to the connecting component 20. The air dissolving component 30 is configured to mix the water flow and gas entering through the first opening 34 in the air dissolving cavity 321 to form a gas-liquid mixed fluid, and flow out from the second opening 35.

[0037] In this embodiment, the connection component 20 includes a first check valve 21, a second check valve 22, and a lever 23. Among them, the first check valve 21 is connected to the water inlet passage 41 and is configured to allow water to flow unidirectionally into the first check valve 21; the second check valve 22 is provided at the air inlet of the air intake device 10 and is configured to allow the gas in the air intake device 10 to flow out unidirectionally from the second check valve 22; the lever 23 is connected to the first check valve 21 and the second check valve 22, and one end thereof is rotatably connected to the inside of the housing of the connection component 20. The lever 23 is configured to drive the second check valve 22 to open when the first check valve 21 is opened, so that gas and water flow into the dissolved air component 30.

[0038] Combined with Figure 2 As shown, in the above embodiment, the first check valve 21 and the second check valve 22 are existing products, which include a push rod 211, a seal, and a spring. The lever 23 includes a first ridge, a second ridge, and a fulcrum. The first ridge presses against the tail of the push rod 211 of the first check valve 21. The second ridge is provided between the fulcrum of the lever 23 and the first ridge and presses against the head of the push rod 211 of the second check valve 22. When the microbubble function switch is turned on, under the action of water pressure, the push rod 211 of the check valve moves downward, pushing open the first ridge, driving the lever 23 to rotate along the fulcrum, and at the same time driving the second ridge to push up the push rod 211, opening the air intake device 10, thereby introducing gas. At this time, water also flows in from the first check valve 21 and flows into the dissolved air component 30 through the diversion channel inside the connection component 20. The gas also enters the dissolved air component 30 through the air guide channel inside the connection component 20; Another check valve can be installed in the air intake device 10 to prevent water from entering; when the microbubble water function is turned off, the water pressure disappears, and the check valve returns to its original state under the action of the spring, thereby closing the air intake device 10. As a preferred embodiment, the diversion channel and the air guide channel can be independent of each other to prevent excessive water pressure from entering the air intake device 10.

[0039] The intake device 10 is a replaceable gas storage tank 11, which includes a gas storage tank 11 and a gas tank connector 12. The gas storage tank 11 is connected to the connection assembly 20 through the gas tank connector 12. The gas tank is a replaceable gas tank, and when replacing, the gas tank can be directly pulled out from the connector; the gas storage tank 11 is preset with compressed gas, and the gas can be carbon dioxide, oxygen, nitrogen, etc. Of course, the gases that can be used are not limited to this. In a preferred embodiment, a pressure indicator is provided on the gas storage tank 11, and the user can understand the gas remaining in the gas storage tank 11 according to the pressure indicator, reminding the user to replace the gas storage tank 11. Of course, the intake device 10 can also directly introduce high-pressure gas and communicate with an external gas source. As a preferred embodiment, the gas storage tank 11 is adopted here.

[0040] As shown in combination with Figure 2 The dissolved air component 30 includes an upper cover 31, a separator 32 and a dissolved air tank 33. The upper cover 31 is provided with the first opening 34, and the bottom of the dissolved air tank 33 is provided with the second opening 35; the dissolved air cavity 321 is arranged inside the separator 32. The separator 32 is arranged inside the dissolved air tank 33 and there is a gap for the supply of gas-liquid mixed fluid to flow between the separator 32 and the inner wall of the dissolved air tank 33; the end opening of the separator 32 is connected to the upper cover 31, and it is configured such that when gas and water flow enter from the upper cover 31, they are mixed in the separation cavity to form a gas-liquid mixed fluid, and then flow out from above the separator 32, enter the gap, and flow out from the second opening 35. The separator 32 in this embodiment is cup-shaped, with an opening at the cup top, two cup ears are provided at the opening, and two cup feet are provided at the cup bottom. The cup feet are placed around the second opening 35, so that there is a gap between the separator 32 and the dissolved air tank 33 for the gas-liquid mixed fluid to pass through; the upper cover 31 seals the mouth of the dissolved air tank 33, and the separator 32 is completely sealed inside the dissolved air tank 33, and the diameter of the first opening 34 is smaller than the mouth of the separator 32. In this way, when gas and water flow enter from the first opening 34, they will directly rush into the bottom of the separator 32 and merge with each other under the action of the impact force to form a gas-liquid mixed fluid. The gas-liquid mixed fluid will flow upward from the edge of the separator 32, enter the gap between the outer wall of the separator 32 and the inner wall of the dissolved air tank 33, and then enter the conduit from the second opening 35 and reach the shower head 50.

[0041] Through the above solution, the dissolved air device of the shower has a simple structure, reduces the production and use costs, eliminates the potential safety hazards of using electricity in the way of using an electric pump, improves the gas-liquid mixing effect at the same time, and reduces the problem of hole blockage; and through the replaceable gas storage tank 11 method, it is also convenient for users to replace the gas source in time and convenient for users to use.

[0042] In this embodiment, the dissolved air assembly 30 is disposed inside the body 40 of the shower, and the air inlet device 10 is disposed outside the body 40. The microbubble generating device in this embodiment can adopt a variety of technologies. For example, microbubbles can be generated by setting a fine filter, or microbubble water can be released by setting a pressure reducing device, or other existing microbubble shower heads can be used. The microbubble scheme used belongs to the prior art and will not be elaborated here.

[0043] By adopting the above technical solutions, the present invention can achieve the following technical effects: The present invention optimizes the gas-liquid mixing device of the microbubble function shower by setting the connection assembly 20, the air inlet device 10 and the dissolved air device, and directly controls the movement of the connection assembly 20 by the action of water pressure, thereby controlling the opening and closing of the air inlet device 10, and flowing into the shower head 50 after being fully mixed in the dissolved air device. On the one hand, the structure of the gas-liquid mixing device is simple, reducing the production and use costs. On the other hand, the gas-liquid mixing effect is also improved, thereby improving the microbubble effect of the microbubble function shower.

[0044] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
