[0052] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0053] refer to Figure 1-Figure 10 A bubble generating device is suitable for being detachably mounted on a faucet, which may be a faucet on a bathtub or a sink.

[0054] refer to Figure 1-Figure 4 The bubble generating device includes a main body 1, a sealing member 2, an infusion member 3, a blowing member 4, a driving member 5, and a one-way air inlet valve 6.

[0055] The body 1 includes a joint 11 and a main body, and the joint 11 is suitable for detachable connection with the faucet. For details, refer to Figure 3 The outer wall of the joint 11 is provided with a threaded section 111, and the threaded section 111 is suitable for being threadedly connected with the faucet.

[0056] refer to Figure 3The main body is universally connected to the joint 11, and the universal connection can be a ball head connection, a universal joint or other forms. The main body includes a rotating part 13 and a shell 12. Among them, the shell 12 is universally connected to the joint 11, and is provided with a water inlet hole 121, a liquid storage chamber 122, and a liquid passage 123 suitable for being connected in sequence. When the joint 11 is connected to the faucet, the water inlet hole 121 is connected to the faucet, so that the water flowing out of the faucet can enter the bubble generating device through the water inlet hole 121. The liquid storage chamber 122 has four water inlet ends connected to the water outlet end of the water inlet hole 121 for water inlet. The liquid storage chamber 122 stores a medium suitable for mixing with water to form a foam liquid, and the medium can be either solid or liquid. The liquid storage chamber 122 is made of a transparent material, so as to be suitable for observing the amount of medium or foam liquid inside the liquid storage chamber 122 and replenishing it accordingly. The liquid storage chamber 122 is formed by enclosing at least two detachable parts to replenish the medium.

[0057] refer to Figure 8 The liquid inlet end of the liquid passage 123 is connected to the liquid storage chamber 122 , the liquid passage 123 is formed by a hose 124 , and the liquid outlet end of the liquid passage 123 is suitable for connecting to the bubble outlet 131 on the rotating member 13 .

[0058] refer to Fig. 9 , Fig.10 The rotating member 13 is connected to the housing 12 for rotation around the first axis, and the rotating member 13 is supported by the housing 12. The rotating member 13 is provided with a plurality of bubble outlets 131 arranged around the first axis, and the rotating member 13 is suitable for being driven by hydraulic force or the driving member 5 to rotate relative to the housing 12, so that the liquid outlet end of the liquid passage 123 is correspondingly connected to each bubble outlet 131, and each bubble outlet 131 corresponds to the blowing member 4. Furthermore, since the main body is universally connected to the joint 11, the bubble outlet direction of the bubble outlet 131 can be further changed by manually adjusting the parking angle of the main body relative to the joint 11.

[0059] refer to Figure 3 , Figure 4 The sealing member 2 is mounted on the body 1, and is suitable for opening the water inlet hole 121 under the action of water pressure, and sealing the water inlet hole 121 when not under the action of water pressure. Specifically, in this embodiment, the sealing member 2 includes a force-applying member 21 and a moving member 22. In this embodiment, the moving member 22 is suitable for sliding relative to the body 1, and the moving member 22 is suitable for sliding in a direction away from the water inlet hole 121 under the action of water pressure to break away from the sealing top contact with the hole wall of the water inlet hole 121. At this time, the moving member 22 is away from the water inlet hole 121, the water inlet hole 121 is opened, and the water inlet hole 121 is suitable for water to enter the liquid storage chamber 122.

[0060] The force-applying member 21 is a spring in this embodiment. Of course, in other embodiments, the force-applying member 21 can also be a magnetic member, rubber or other member suitable for applying force to the moving member 22 in one direction. Specifically, the two ends of the spring act on the moving member 22 and the housing 12 of the main body 1 respectively, so as to apply a force to the moving member 22 to make it slide toward the hole wall of the water inlet hole 121. When the moving member 22 is not affected by water pressure, force is applied to the moving member 22 to make the moving member 22 slide to the hole wall of the water inlet hole 121, so that the water inlet hole 121 is sealed, and the foam liquid in the liquid storage chamber 122 will not flow out from the water inlet hole 121.

[0061] The method for the moving part 22 to seal the water inlet hole 121 can be any of the following: the moving part 22 can be a flexible part as a whole, such as the moving part 22 being a leather cup, or a part of a flexible part, such as the moving part 22 having a sealing ring to achieve sealing with the hole wall of the water inlet hole 121. Of course, there are other forms of sealing, which will not be described in detail here. In other embodiments, the moving part 22 can also be hinged with the body 1 (the moving part 22 is similar to a flap) to achieve movement relative to the water inlet hole 121 to open or seal the water inlet hole 121.

[0062] In other embodiments, only a partial deformation of the seal 2 (its general position does not move relative to the main body 1) is required. Specifically, the seal 2 is deformed by water pressure to open the water inlet hole 121, and recovers to seal the water inlet hole 121 when no water pressure is applied. This embodiment lists several feasible methods. For example, the seal 2 is a one-way sealing ring, or a duckbill valve (which expands under pressure when water is introduced to open the water inlet hole 121, and recovers to close the water inlet hole 121 when no water is introduced).

[0063] refer to Figure 6 , Figure 7 The infusion component 3 is installed on the body 1, and is suitable for conveying the foam liquid in the liquid storage cavity 122 to the bubble outlet 131. In this embodiment, the foam liquid in the liquid storage cavity 122 is mainly output in the form of negative pressure. Specifically, the infusion component 3 is suitable for squeezing and relaxing the hose 124, so that the liquid passage 123 is at a negative pressure relative to the liquid storage cavity 122, and the foam liquid in the liquid storage cavity 122 is squeezed out by the atmospheric pressure, so that the foam liquid in the liquid storage cavity 122 is conveyed to the bubble outlet 131 through the liquid passage 123.

[0064] As for the squeezing and relaxing mode of the infusion component 3, this embodiment cites two implementation modes, such as the infusion component 3 is suitable for sliding or rotating relative to the hose 124 to squeeze and relax the hose 124. Take the rotation of the infusion component 3 relative to the hose 124 as an example. The housing 12 is provided with a mounting cavity 125, the cavity wall of the mounting cavity 125 is made of hard material, the cross section of the mounting cavity 125 is roughly n-shaped, the hose 124 is placed in the mounting cavity 125 and fits the cavity wall of the mounting cavity 125, and the infusion component 3 is provided with a squeezing column 31, and the squeezing column 31 can be only one or more, and in this embodiment, two are provided. The squeezing column 31 fits with the side of the hose 124 away from the cavity wall of the mounting cavity 125, and squeezes the hose 124. When the infusion component 3 rotates, the squeezing column 31 changes position to squeeze different positions of the hose 124, and at the same time, the previously squeezed part of the hose 124 is not squeezed, and negative pressure is generated through this process, and the same position is squeezed again after another rotation, so as to continuously suck. By arranging a plurality of squeezing positions, the suction effect can be better. In other embodiments, the squeezing or relaxation of the hose 124 can be achieved by the movement of the infusion parts 3 arranged on both sides of the hose 124, without relying on the cavity wall of the mounting cavity 125.

[0065] Of course, in other embodiments, if the infusion device 3 is a pump, the liquid extraction may not be achieved by squeezing and loosening the hose 124, and the foam liquid in the liquid storage chamber 122 may be directly extracted by the suction force applied by the pump.

[0066] refer to Figure 6 , Figure 7 The blowing member 4 is mounted on the main body 1 and is suitable for blowing out the foam liquid in the bubble outlet 131 to form bubbles. In this embodiment, the wind force is generated by the rotation of the impeller.

[0067] refer to Figure 6 , Figure 7 , Fig. 9 , Fig.10 There is one driving member 5, and the driving member 5 is suitable for driving the infusion member 3, the blowing member 4 and the rotating member 13 to work.

[0068] Specifically, the driving member 5 is a rotating motor, one end of which outputs power to the blowing member 4 for rotation, and the other end transmits the power to the infusion member 3 (whose outer wall has a tooth portion) and the rotating member 13 (the inner ring has a tooth portion) through a gear set, thereby realizing the rotation of the infusion member 3 and the rotating member 13.

[0069] refer to Figure 3 The air inlet end of the one-way air inlet valve 6 is connected to the atmosphere, and the air outlet end is connected to the liquid storage chamber 122 to prevent vacuum in the liquid storage chamber 122, which would result in failure to output foam liquid.

[0070] When in use, ensure that there is medium in the liquid storage chamber 122, connect the connector 11 to the faucet, open the water path of the faucet, and refer to Figure 4 The moving part 22 slides under the action of water pressure, thereby moving away from the hole wall of the water inlet hole 121, the water inlet hole 121 opens, and the force-applying part 21 stores energy, and water enters the liquid storage chamber 122 from the water inlet hole 121 to mix with the medium to form foam liquid.

[0071] refer to Figure 3 By observing the foam liquid content in the liquid storage chamber 122, the faucet is closed, and the force-applying member 21 releases energy, causing the moving member 22 to slide toward the hole wall of the water inlet hole 121, thereby sealing against the hole wall of the water inlet hole 121 to seal the water inlet hole 121. If the faucet is removed at this time, the liquid in the liquid storage chamber 122 will not flow out from the one-way air inlet valve 6 and the water inlet hole 121.

[0072] Turn on the driving member 5, the driving member 5 drives the infusion member 3, the blowing member 4 and the rotating member 13 to rotate, Figure 3 , Figure 6 The infusion piece 3 squeezes the hose 124 by rotating, so that negative pressure is formed at the squeezing point. Under the action of atmospheric pressure, the foam liquid in the liquid storage chamber 122 is transported to the bubble outlet 131 through the liquid passage 123. Since the one-way air inlet valve 6 is connected to the liquid storage chamber 122, no vacuum is formed in the liquid storage chamber 122.

[0073] refer to Fig. 9 , Fig.10 The foam liquid at the bubble outlet 131 rotates with the rotating member 13 until the bubble outlet 131 corresponds to the blowing member 4, and the wind force generated by the blowing member 4 blows the bubbles out. Figure 3 , Figure 4 When the direction of blowing bubbles needs to be changed, the corresponding angle can be changed by making the main body rotate universally relative to the joint 11.

[0074] Compared with the prior art, this embodiment has the following beneficial effects:

[0075] In an exemplary embodiment, a bubble generating device is suitable for being detachably mounted on a faucet, and includes a body 1, a sealing member 2, an infusion member 3, and a blowing member 4. The body 1 is provided with a water inlet hole 121, a liquid storage chamber 122, and a bubble outlet 131 which are connected in sequence. The water inlet hole 121 is suitable for being connected to the faucet, and the liquid storage chamber 122 stores a medium suitable for mixing with water to form a foam liquid; the sealing member 2 is installed on the body 1, and is suitable for being subjected to water pressure to open the water inlet hole 121, so that water can enter the liquid storage chamber 122 through the water inlet hole 121 and mix with the medium to form a foam liquid. When the body 1 is installed on the faucet, the faucet waterway is opened, and due to the large water force generated by the faucet, sufficient impact can be generated to fully mix the water and the medium, which is more convenient and labor-saving than hand-cranked mixing, and there is no need to disassemble to pour water into the liquid storage chamber 122, and children can also perform the above operation. The sealing member 2 seals the water inlet 121 when not under water pressure, thereby preventing the medium or foam liquid from flowing out of the water inlet 121 when the main body 1 is removed from the faucet, resulting in waste. The infusion member 3 is installed on the main body 1, which is suitable for conveying the foam liquid in the liquid storage cavity 122 to the bubble outlet 131, so that the infusion action is performed when it is needed.

The moving member 22 moves when subjected to water pressure and automatically resets under the action of the force-applying member 21, thereby achieving the effect of opening or sealing the water inlet hole 121.

[0077] In an exemplary embodiment, the seal 2 is a flexible member, which is deformed by water pressure to open the water inlet hole 121 and recovers to seal the water inlet hole 121 when not affected by water pressure, thereby achieving the effect of opening or sealing the water inlet hole 121.

The infusion piece 3 is suitable for squeezing and relaxing the hose 124 to form a negative pressure at the squeezing point. Under the action of the negative pressure, the foam liquid in the liquid storage chamber 122 is transported to the bubble outlet 131 through the liquid passage 123. The air inlet end of the one-way air inlet valve 6 is connected to the atmosphere, and the air outlet end of the one-way air inlet valve 6 is connected to the liquid storage chamber 122, so that air is taken into the liquid storage chamber 122 to prevent the liquid storage chamber 122 from being vacuumed when the foam liquid is discharged.

[0079] In an exemplary embodiment, the infusion member 3 is suitable for sliding or rotating relative to the hose 124 to squeeze and relax the hose 124 to achieve the transportation of the foam liquid through the liquid channel 123 .

[0080] In an exemplary embodiment, the main body 1 includes a rotating member 13 and a shell 12, the rotating member 13 is connected to the shell 12 for rotation around a first axis, the rotating member 13 is provided with a plurality of bubble outlets 131 arranged around the first axis, the rotating member 13 is suitable for being driven by hydraulic power or a driving member 5 to rotate relative to the shell 12, so that the liquid outlet end of the liquid passage 123 is correspondingly connected with each bubble outlet 131, so that each bubble outlet 131 can accumulate foam liquid, and each bubble outlet 131 corresponds to the blowing member 4, so that each bubble outlet 131 can form bubbles when corresponding to the blowing member 4, and the bubble effect is better.

[0081] In an exemplary embodiment, a driving member 5 is also included, and the driving member 5 is suitable for driving the infusion member 3, the blowing member 4 and the rotating member 13 to work.
