[0001] This application claims priority to Chinese Patent Application No. 202422076359.9, filed on August 27, 2024, entitled “Foaming Device, Bath Foam Machine and Bathing System”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of bathroom technology, and in particular to a foaming device, a bath foam machine, and a bathing system. Background Technology

[0003] Existing shower systems primarily serve cleaning and massage functions. As people's living standards improve, their demands for quality of life and bathing experience also increase. However, current showerheads only provide basic water flow, and bathrooms typically require separate storage for toiletries such as shower gel and shampoo, which is not only inconvenient but also takes up valuable bathroom space.

[0004] Currently, there are showers on the market with foaming functions, but they have complex piping, take up a lot of space, have many parts, and are more expensive.

[0005] Utility Model Content

[0006] Therefore, it is necessary to provide a foaming device, a bath foam machine, and a bathing system to address the aforementioned problems with existing shower systems.

[0007] The first aspect of this application provides a foaming device, which includes a liquid storage container, a mixing container, a multi-way valve, a liquid extraction device, an air inflation device, and a water circuit switching valve.

[0017] The foaming device in the above embodiments further includes a flow valve between the water switching valve and the mixing container. By adjusting the opening and closing degree of the flow valve, the flow rate of clean water entering the mixing container can be adjusted, thereby adjusting the foaming effect.

[0018] In one embodiment, a first one-way valve is provided between the liquid extraction device and the mixing container.

[0019] The foaming device in the above embodiments further includes a first one-way valve between the liquid extraction device and the mixing container to prevent liquid in the mixing container from flowing back to the liquid extraction device, thereby improving the reliability of the foaming device.

[0040] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0041] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

[0042] As shown in Figures 1 and 3, this embodiment provides a foaming device, which includes a liquid storage container 10, a mixing container 20, a multi-way valve 30, a liquid extraction device 40, an air inflation device 50, and a water circuit switching valve 60.

[0043] The number of liquid storage containers 10 is not less than two, and the not less than two liquid storage containers 10 are selectively connected to the liquid extraction device 40 through a multi-way valve 30;

[0044] The mixing container 20 is connected to the aeration device 50, the liquid extraction device 40, and the water outlet, respectively.

[0045] The water circuit switching valve 60 has a first channel and a second channel. The water outlet can be directly connected to the shower faucet through the first channel, and the mixing container 20 can be connected to the shower faucet through the second channel. The water circuit switching valve 60 is configured to selectively open the first channel or the second channel.

[0046] The liquid storage container 10 can be used to hold cleaning solutions for body cleansing, such as shower gel and shampoo. There can be at least two liquid storage containers 10; for example, one container can hold shower gel, and the other can hold shampoo. It should be noted that in other embodiments, the number of liquid storage containers 10 can be three, four, or similar, so that different brands and types of shower gel or shampoo with different functions can be stored in different containers 10.

[0047] The multi-way valve 30 can be used to selectively connect the liquid extraction device 40 to different liquid storage containers 10 according to cleaning requirements. For example, the multi-way valve 30 is a three-way valve with two inlets and one outlet. One inlet channel of the three-way valve is connected to the liquid storage container 10 containing shower gel, and the other is connected to the liquid storage container 10 containing shampoo. The outlet channel of the three-way valve is connected to the inlet of the liquid extraction device 40. When shampooing is required, the outlet channel of the three-way valve is connected to the liquid storage container 10 containing shampoo and disconnected from the liquid storage container 10 containing shower gel; when showering is required, the outlet channel of the three-way valve is connected to the liquid storage container 10 containing shower gel and disconnected from the liquid storage container 10 containing shampoo. It should be noted that the multi-way valve 30 can also be a four-way valve, a five-way valve, etc., and needs to be configured appropriately according to the number of liquid storage containers 10.

[0048] The pumping device 40 can be used to transfer the cleaning solution in the storage bottle to the mixing container 20. The pumping device 40 can be a positive displacement pump, peristaltic pump, gear pump, diaphragm pump, or screw pump. For example, the pumping device 40 is a peristaltic pump. Because the pumping device 40 selectively connects to multiple storage containers 10 via the multi-way valve 30, different cleaning solutions can be transferred using a single pumping device 40. This not only reduces the overall size of the device but also lowers the overall product cost, improving competitiveness.

[0049] The inflation device 50 can be used to deliver external gas to the mixing container 20. The inflation device 50 can be an air pump structure, with its air inlet connected to the outside atmosphere and its other end connected to the mixing container 20. After the air pump structure is started, it can deliver gas to the mixing container 20. It should be noted that in some embodiments, the inflation device 50 and the liquid extraction device 40 are integrated into one structure.

[0050] The shower faucet can be used to control the connection or disconnection between the water supply source and the water circuit switching valve 60. Specifically, when the shower faucet is in the open state, the water supply source and the water circuit switching valve 60 are connected, and the water supply source delivers clean water to the water circuit switching valve 60; when the shower faucet changes from the open state to the closed state, the connection between the water supply source and the water circuit switching valve 60 is cut off, and the water supply source stops delivering clean water to the water circuit switching valve 60. It should be noted that in some embodiments, the water supply source includes a hot water supply and a cold water supply, and the shower faucet is equipped with a thermostatic valve, which can adjust the temperature of the clean water delivered by the water supply source to the water circuit switching valve 60.

[0051] The water outlet can be one or a combination of a handheld shower head, an overhead shower head, or a combination thereof. For example, the water outlet is a handheld shower head from which foam formed in the mixing container 20 is sprayed.

[0052] In the foaming device described in the above embodiments, the inflation device 50 can be used to deliver external gas to the mixing container 20, and the liquid extraction device 40 can be used to deliver the cleaning liquid in the storage container 10 to the mixing container 20. By setting at least two storage containers 10, different cleaning liquids can be selected for foaming according to actual cleaning requirements. Based on the fact that at least two storage containers 10 are selectively connected to the liquid extraction device 40 through a multi-way valve 30, and the liquid outlet of the multi-way valve 30 is connected to the liquid inlet of the liquid extraction device 40, different cleaning liquids can be delivered through one liquid extraction device 40, which not only reduces the overall size of the device, but also reduces the overall cost of the product and improves competitiveness.

[0053] As shown in Figure 1, in addition to the features of the above embodiments, this embodiment further specifies that: the water circuit switching valve 60 is electrically connected to the multi-way valve 30, the water circuit switching valve 60 includes multiple working positions, and the multi-way valve 30 selects one of the liquid storage containers 10 to connect with the liquid pumping device 40 according to the current working position of the water circuit switching valve 60.

[0054] In the above embodiments, the water circuit switching valve 60 and the multi-way valve 30 are further electrically connected. By switching the working position of the water circuit switching valve 60, the liquid inlet channel of the multi-way valve 30 corresponding to the current working position can be opened. Then, different cleaning liquids can be delivered to the mixing container 20 through a liquid pumping device 40, thereby reducing the size of the device.

[0055] The water switching valve 60 may include multiple operating positions, such as a clean water position, a shower gel position, and a shampoo position. When the water switching valve 60 is in the clean water position, the second channel of the water switching valve 60 is closed, and the first channel is open, allowing clean water from the water source to be directly delivered to the water dispenser via the first channel. When the water switching valve 60 is in the shower gel position, the first channel of the water switching valve 60 is closed, and the second channel is open. At this time, the multi-way valve 30 is connected to the storage container 10 containing shower gel, and the shower gel is delivered to the mixing container 20 via the pumping device 40. When the water switching valve 60 is in the shampoo position, the first channel of the water switching valve 60 is closed, and the second channel is open. At this time, the multi-way valve 30 is connected to the storage container 10 containing shampoo, and the shampoo is delivered to the mixing container 20 via the pumping device 40.

[0056] It should be noted that in some embodiments, the water circuit switching valve 60 is provided with the same number of microswitches as the liquid storage container 10. The microswitches are electrically connected to the multi-channel. When the water circuit switching valve 60 switches to a different working position, the microswitch corresponding to the working position is triggered, thereby controlling the corresponding liquid inlet channel in the multi-way valve 30 to be open.

[0057] As shown in Figure 3, in addition to the features of the above embodiments, this embodiment further specifies that the water circuit switching valve 60 is a manual mechanical valve.

[0058] In the above embodiments, the water circuit switching valve 60 is further defined as a manual mechanical valve. Based on this design, even if the device experiences a power outage, it will not affect the water outlet from spraying clean water.

[0059] The water circuit switching valve 60 can be manually rotated to switch its working position.

[0060] As shown in Figure 1, in addition to the features of the above embodiments, this embodiment further specifies that: a flow valve 70 is provided between the water switching valve 60 and the mixing container 20, and when the flow valve 70 is configured to be open in the second channel, it adjusts the flow rate of clean water entering the mixing container 20.

[0061] In the above embodiment, a flow valve 70 is further provided between the water switching valve 60 and the mixing container 20. By adjusting the opening and closing degree of the flow valve 70, the flow rate of clean water entering the mixing container 20 can be adjusted, thereby adjusting the foaming effect.

[0062] The flow valve 70 can be used to control the amount of water entering the mixing container 20. When the foam effect sprayed by the water outlet is too thin, the flow valve 70 is used to reduce the amount of clean water entering the mixing container 20. When the foam effect sprayed by the water outlet is too dense, the flow valve 70 is used to increase the amount of clean water entering the mixing container 20.

[0063] As shown in Figure 2, in addition to the features of the above embodiments, this embodiment further specifies that a first one-way valve 91 is provided between the liquid extraction device 40 and the mixing container 20.

[0064] In the above embodiments, a first one-way valve 91 is further provided between the liquid extraction device 40 and the mixing container 20 to prevent the liquid in the mixing container 20 from flowing back to the liquid extraction device 40, thereby improving the reliability of the foaming device.

[0065] As shown in Figure 2, in addition to the features of the above embodiments, this embodiment further specifies that a second one-way valve 92 is provided between the inflation device 50 and the mixing container 20.

[0066] In the above embodiments, a second one-way valve 92 is further provided between the inflation device 50 and the mixing container 20 to prevent the liquid in the mixing container 20 from flowing back to the inflation device 50, thereby improving the reliability of the foaming device.

[0067] As shown in Figures 2 and 3, in addition to the features of the above embodiments, this embodiment further specifies that: the foaming device also includes a silencing pipe 80, the air inlet end of the silencing pipe 80 is connected to the outside atmosphere, and the air outlet end of the silencing pipe 80 is connected to the air inlet end of the inflation device 50.

[0068] In the above embodiments, the airflow needs to pass through a silencer before entering the inflation device 50 to reduce noise and prevent the noise generated by the inflation device 50 from affecting the user experience.

[0069] The silencer includes a sleeve, which is a shell structure with open ends. Sound-absorbing cotton is installed inside the sleeve. When airflow enters the silencer, the noise generated is absorbed by the sound-absorbing cotton, thereby reducing the noise generated by the inflation device 50.

[0070] In addition to the features of the above embodiments, this embodiment further specifies that the foaming device also includes a battery module, which supplies power to the multi-way valve 30, the liquid extraction device 40, and the air filling device 50.

[0071] The above embodiments further specify that the foaming device is equipped with a battery module to power the multi-way valve 30, the liquid extraction device 40 and the air inflation device 50, so as to avoid dangerous situations such as short circuits caused by using mains power in the bathroom.

[0072] The battery module can be a rechargeable battery, which can be removed from the casing for charging, avoiding the use of mains power and reducing the risk of short circuits caused by high humidity in the bathroom.

[0073] As shown in Figure 2, in addition to the features of the above embodiments, this embodiment further specifies that: a foamer 93 is provided between the mixing container 20 and the water outlet. The foamer 93 includes a foaming tube and foam cotton. The foam cotton is located inside the foaming tube. The liquid inlet end of the foaming tube is connected to the liquid outlet end of the mixing container 20, and the liquid outlet end of the foaming tube is connected to the liquid inlet end of the water outlet. The foaming tube and the mixing container 20 are detachably connected.

[0074] The foam can be a cotton structure with multiple small holes. The gas-liquid mixture after exiting the mixing container 20 enters the foaming tube. The gas-liquid mixture forms uniform foam after passing through the foam, resulting in better bubble effect. The foaming tube is detachably connected to the mixing container 20 to avoid the foamer 93 becoming clogged due to time, water quality, or other reasons, which would affect the foaming effect. It is also easy to remove, replace, and clean.

[0075] As shown in Figure 4, this embodiment provides a bath foam machine, which includes:

[0076] The aforementioned foaming device;

[0077] The outer shell has an internal mounting cavity. The mixing container 20, multi-way valve 30, liquid extraction device 40, and air filling device 50 are installed in the mounting cavity. The liquid storage container 10 is detachably connected to the outer shell.

[0078] The outer casing can be, but is not limited to, a metal or non-metal casing. For example, the casing can be a plastic casing. The casing can be elongated. An installation cavity is formed inside the casing, within which the mixing container 20, multi-way valve 30, liquid extraction device 40, and inflation device 50 can be installed. The casing can be fixed to a bathroom wall. For example, the casing can be fixed to the bathroom wall using screws, hooks, clips, slide rails, etc.

[0079] This embodiment provides a bathing system, which includes:

[0080] The aforementioned bath foam machine;

[0081] A shower faucet, with its inlet connected to the water supply and its outlet connected to a shower foam machine.

[0082] The water outlet is directly connected to the first channel and the mixing container 20.

[0083] For details regarding shower faucets and water dispensers, please refer to the above text; they will not be repeated here.

[0084] In addition to the features of the above embodiments, this embodiment further specifies that: the shower faucet has a mixing chamber and a hot water channel and a cold water channel communicating with the mixing chamber, and a thermostatic valve is provided in the mixing chamber, the thermostatic valve being configured to control the degree of conduction of the hot water channel and / or the cold water channel.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
