DETAILED DESCRIPTION OF THE INVENTION

[0028] The present invention will be described in detail below with reference to FIGS.

[0029] The shower device is a water supply switching device including a water supply port 101, a first drain port 102 and a second drain port 103 communicating with the water supply port 101, and a switching member 104 for controlling communication between the water supply port 101 and the first drain port 102 or the second drain port 103; A shower module 20 is typically composed of a water outlet device such as a shower head or ceiling shower, and its water supply end communicates with a first drain outlet 102; a foaming module (30) including a foaming port (6054) and a liquid supply port connected to a second drain port (103); a first dispensing device connected to the dispensing port for providing a body care product; When the water inlet 101 is connected to the first drain outlet 102, water flows out of the shower module 20; when the water inlet 101 is connected to the second drain outlet 103, water flows out of the second drain outlet 103, enters the foaming module 30 via the water inlet, mixes with the body care product, and then foams from the foaming outlet 6054.

[0030] In the shower system proposed in this embodiment, the shower module 20 and foaming module 30 are separably connected, making it suitable for users who already have a shower module installed in their home, reducing replacement costs. By optimizing a conventional shower system into a foaming shower system, the user experience can be improved. Furthermore, the separate structure is simpler, has lower production costs than an integrated structure, and is easier to maintain.

[0031] In this embodiment, the water supply switching device includes a valve 10. The valve 10 is provided with a water supply inlet 101, a first drain outlet 102 and a second drain outlet 103 that communicate with the water supply inlet 101, and a switching member 104. A return spring 105 is provided between the switching member 104 and the valve 10. A switch 106, one end of which is connected to the switching member 104, is provided on the outside of the valve 10. When water is not being supplied, the switching member 104 closes the second drain outlet 103 due to the elastic force of the return spring 105. Therefore, as shown in FIG. 9 , in the initial state, the switching member 104 closes the second drain outlet 103, and the water supply inlet 101 communicates with the first drain outlet 102. When water is supplied in this state, water flows into the shower apparatus. As shown in Figure 10, when one end of switch 106 is pressed, switching member 104 moves, and at this time, the water supply pressure overcomes the elastic force of return spring 105, switching member 104 remains in a state where it closes first drain outlet 102 and opens second drain outlet 103, allowing water to flow to foaming device 60. When water needs to be released from the shower device, the other end of switch 106 is pressed, causing switching member 104 to move, and the elastic force of return spring 105 causes it to return to its initial state, at which point water will flow from the shower device.

[0032] In this embodiment, the foaming module 30 includes a power supply 40, a controller connected to the power supply 40, and an air supply device 50, which is usually composed of an air pump. The foaming module 30 further includes a foaming device 60, which is provided with a foaming cavity 6031, a liquid supply port connected to the foaming cavity 6031, and a foaming port 6054. The liquid supply port includes a raw water supply port 6051 connected to the second drain port 103, and a foaming liquid inlet 6053 connected to the first liquid supply device. The foaming device 60 is provided with an air intake port 6052 communicating with the foaming cavity 6031, and the air intake port 6052 communicating with the exhaust port of the air intake device 50.

[0033] In this embodiment, the first liquid supply device includes a plurality of storage spaces A701 and a switching valve 80. The switching valve 80 is provided with a plurality of inlets connected to the respective storage spaces A701 in a one-to-one relationship, and the outlet of the switching valve 80 is connected to the foaming liquid inlet 6053.

[0034] During use, the switching valve 80 supplies at least two types of foaming liquid, such as body soap and shampoo, to the foaming device 60, thereby eliminating the need for additional containers in the bathroom and improving the overall aesthetics of the bathroom. The water supply switching device directs the water flow to either the shower device or the foaming device 60, allowing the shower water and foam to flow through two independent paths, preventing the body soap and shampoo from being wasted and wasted along with the shower water. The foamed body soap and shampoo are then easily and uniformly applied to the body and hair, improving the user experience.

[0035] 4 to 6, the foaming device 60 includes a nozzle 601, a coupling device, and a foaming body 603, which are connected in sequence along the foaming direction. Specifically, the inlet end of the nozzle 601 forms a raw water supply port 6051, a negative pressure chamber 6022 is provided at the inlet end of the coupling device, the radial dimension of the outlet end of the nozzle 601 is smaller than the radial dimension of the negative pressure chamber 6022, a foaming liquid inlet 6053 communicates with the negative pressure chamber 6022, the internal space of the foaming body 603 forms a foaming cavity 6031, a foam 604 is provided in the foaming cavity 6031, and an air intake 6052 communicating with the foaming cavity 6031 is provided in the coupling device.

[0036] In this embodiment, as shown in FIG. 7 , the raw water supply port 6051 is connected to the second drain port 103, and the air intake port 6052 is connected to the exhaust port of the air supply device 50. During use, water is sprayed from the nozzle 601, generating negative pressure in the negative pressure chamber 6022, which causes the foamable liquid in the storage space A701 to be sucked into the negative pressure chamber 6022 and flow to the foam body 604 along with the water flow. The air supply device 50 also supplies air into the foaming cavity 6031, and performs a foaming operation on the foamable mixed liquid and air that pass through the foam body 604, forming bubbles that are then discharged from the foaming port 6054. In another embodiment, the raw water supply port 6051 is connected to the exhaust port of the air supply device 50, and the air intake port 6052 is connected to the second drain port 103. As shown in FIG. 8, the foaming liquid enters the foaming cavity 6031 together with the air flow under the action of negative pressure, and the water flow enters the foaming cavity 6031 through the air inlet 6052, and the subsequent foaming process is the same as described above.

[0037] In this embodiment, since the cross-sectional flow area of ​​the outlet end of the nozzle 601 is smaller than that of the inlet end, the fluid flowing through the nozzle 601 is compressed, its flow rate increases, the pressure on the fluid surface decreases, and negative pressure is generated in the negative pressure chamber 6022. In addition, as shown in Fig. 5, since the negative pressure region is mainly concentrated at the rear part of the outlet end of the nozzle 601, the foaming liquid inlet 6053 is located at the rear part of the outlet end of the nozzle 601.

[0038] In this embodiment, the coupling device includes a first connecting member 6021 and a second connecting member 6023 that are connected to each other. The first connecting member 6021 is provided with a negative pressure chamber 6022 and a foaming liquid inlet 6053 connected to the negative pressure chamber 6022, and the second connecting member 6023 is provided with an air intake 6052. In addition, a check valve 606 that opens in one direction along the foaming direction is provided between the first connecting member 6021 and the second connecting member 6023 to prevent backflow of the fluid.

[0039] In this embodiment, the system further includes a first suction pump 901 and a flow sensor 110 electrically connected to the controller. The first suction pump 901 is located between the switching valve 80 and the foaming liquid inlet 6053, and the flow sensor 110 is located between the second drain outlet 103 and the raw water supply port 6051. When the flow sensor 110 detects water flow, the controller activates the air supply device 50 and the first suction pump 901. When the flow sensor 110 does not detect water flow, the controller deactivates the air supply device 50 and the first suction pump 901. This realizes automatic activation and deactivation of the air supply device 50 and the first suction pump 901, stabilizes the amount of air supply and the amount of foaming liquid supply, and further stabilizes the foaming effect. In another embodiment, when the air intake port 6052 is used as the water supply port 101, the flow sensor 110 is located between the second drain outlet 103 and the air intake port 6052, and the beneficial effects are the same as those described above.

[0040] In this embodiment, the device further includes a second liquid supply device. The second liquid supply device includes a storage space B702, a second suction pump 902 communicating with the storage space B702, and an activation switch 100 for activating the second suction pump 902. The second suction pump 902 and the activation switch 100 are electrically connected to a controller. The storage space B702 and the storage space A701 are distinguished by the fact that the storage space A701 is used to store foaming liquid and the storage space B702 is used to store non-foaming liquid, thereby meeting various user requirements. Furthermore, the activation switch 100 is an inductive switch, and types of inductive switches include, but are not limited to, laser, infrared, and capacitance. This allows the user to dispense liquid without contact, improving the user experience.

[0041] In this embodiment, the device further includes a housing 120 in which an installation space 1201 and a storage space 1202 are installed. The control device, the air supply device 50, the foaming device 60, the first liquid supply device, and the second liquid supply device are all installed in the installation space 1201. The drain port 180 of the second liquid supply device, i.e., the outlet of the second suction pump 902, is installed on the ceiling wall of the storage space 1202. An activation switch 100 is installed near the drain port 180 to easily detect user operation. The selector switch of the switching valve 80 is installed so as to penetrate the surface of the housing 120, or a handle 130 operably connected to the selector switch is provided on the surface of the housing 120. An internal case 140 is installed at the top of the installation space 1201. A plurality of partitions are provided within the internal case 140, thereby dividing the space of the internal case 140 into a plurality of spaces. Each space comprises a battery case 703 for mounting a power module, a storage space A 701, and a storage space B 702. By providing the storage space 1202, unused space in the housing 120 can be effectively utilized, providing convenience for the user to temporarily store small items such as eyeglasses and accessories.

[0042] In this embodiment, the device further includes a cover 150 and a foaming head 160. The cover 150 can open and close the mounting space 1201, thereby preventing dust and moisture from entering the mounting space. The foaming head 160 is connected to the foaming port 6054 of the foaming device 60 and can be magnetically attached to the housing 120. Compared with the recessed fitting used in the prior art, the magnetic attachment method makes detachment by magnetic attachment more convenient and improves the aesthetic appearance of the housing 120.

[0043] In this embodiment, the system further includes a mixer tap 170. The mixer tap 170 is provided with a hot water inlet, a cold water inlet, and a mixed water outlet. The hot water inlet is connected to the hot water pipe, the cold water inlet is connected to the cold water pipe, and the mixed water outlet is connected to the water supply port 101 of the switching device.

[0044] The shower device proposed in this embodiment is used as follows.

[0045] In the initial state, the switching member 104 closes the second drain outlet 103 and opens the first drain outlet 102, allowing water to flow into the shower device while the user is taking a shower. After the shower, if body soap or shampoo needs to be applied, one end of the switch 106 is pressed, causing the switching member 104 to close the first drain outlet 102 and open the second drain outlet 103, allowing water to flow to the foaming device 60. In this case, the flow sensor 110 detects the water flow path, and the controller activates the air pump and first suction pump 901, causing foam to be sprayed from the foaming head 160, completing foaming and allowing the user to apply the foam to their body surface or hair.

[0046] After application is complete, pressing the other end of the switch 106 causes the switching member 104 to close the second drain outlet 103 and open the first drain outlet 102, the flow sensor 110 is no longer able to detect the water flow path, the controller stops the air pump and first suction pump 901, ends foaming, and water comes out of the shower device to wash away the foam.
