[0048] The following is combined Figure 1-10 This utility model will be described in detail.

[0049] A shower device includes a water inlet switching device, which has a water inlet 101 and a first water outlet 102 and a second water outlet 103 connected to the water inlet 101, and also includes a switching element 104 for controlling the water inlet 101 to be connected to the first water outlet 102 or the second water outlet 103.

[0050] Shower module 20, typically using a shower head, overhead spray or other water outlet device, has its inlet end connected to the first water outlet 102;

[0051] The foaming module 30 includes a liquid inlet and a foam outlet 6054, with the liquid inlet connected to the second water outlet 103.

[0052] The first liquid dispensing device, connected to the liquid inlet, is used to provide nursing solution;

[0053] When the inlet 101 is connected to the first outlet 102, the shower module 20 outputs water; when the inlet 101 is connected to the second outlet 103, water flows out from the second outlet 103, enters the foaming module 30 from the liquid inlet, mixes with the care solution, and generates foam from the foam outlet 6054.

[0054] The shower device proposed in this embodiment allows the shower module 20 and the foaming module 30 to be connected separately, thus making it suitable for users who have already installed the shower module 20 at home, reducing their replacement costs, optimizing the original ordinary shower device into a shower device with foaming function, and improving the user experience; at the same time, the separate design structure is simpler, the production cost is lower than that of the integrated type, and it is easier to maintain.

[0055] In this embodiment, the water inlet switching device includes a valve body 10. The valve body 10 has a water inlet 101, a first water outlet 102 and a second water outlet 103 connected to the water inlet 101, and a switching element 104. A return spring 105 is provided between the switching element 104 and the valve body 10. A switch 106 is provided outside the valve body 10, and one end of the switch 106 is connected to the switching element 104. When no water is entering, the switching element 104 closes the second water outlet 103 under the elastic force of the return spring 105. Therefore, in the default state, the switching element 104 closes the second water outlet 103, and the water inlet 101 is connected to the first water outlet 102. If water enters at this time, the water flows to the shower device, such as... Figure 9 As shown; pressing one end of switch 106 causes the switching element 104 to move. At this time, the inlet water pressure overcomes the elastic force of the reset spring 105, keeping the switching element 104 in the state of closing the first outlet 102 and opening the second outlet 103. The water flows to the aerator 60, as shown. Figure 10 As shown. If water is needed from the shower, press the other end of switch 106 to move switch 104. Under the elastic force of reset spring 105, switch 104 returns to the default state, and water is then released from the shower.

[0056] In this embodiment, the foaming module 30 includes a power supply 40 and a controller and an air supply device 50 connected to the power supply 40. The air supply device 50 is usually an air pump. It also includes a foaming device 60, which has a foaming chamber 6031 and a liquid inlet and a foam outlet 6054 connected to the foaming chamber 6031. The liquid inlet includes a raw water inlet 6051 connected to the second water outlet 103 and a foaming liquid inlet 6053 connected to the first liquid supply device. The foaming device 60 also has an air inlet 6052 connected to the foaming chamber 6031 and connected to the air outlet of the air supply device 50.

[0057] In this embodiment, the first liquid supply device includes several liquid storage chambers A701 and a switching valve 80. The switching valve 80 has multiple inlets and is paired with each liquid storage chamber A701. The outlet of the switching valve 80 is connected to the foaming liquid inlet 6053.

[0058] In use, at least two foaming liquids, such as shower gel and shampoo, are supplied to the foaming device 60 via the switching valve 80, avoiding the need to place related containers in the bathroom and improving the overall aesthetics of the bathroom. At the same time, the water inlet switching device directs the water flow to the shower device or the foaming device 60, so that the shower water and foam flow out from two independent channels, avoiding waste caused by the shower gel and shampoo flowing out with the shower water. Furthermore, the foamed shower gel and shampoo are easier to apply evenly to the body or hair, improving the user experience.

[0059] In this embodiment, as Figures 4-6 As shown, the foaming device 60 includes a nozzle 601, a connecting device, and a foaming body 603 connected sequentially along the foaming direction. Specifically, the inlet end of the nozzle 601 forms a raw water inlet 6051, the inlet end of the connecting device is provided with a negative pressure chamber 6022, the radial dimension of the outlet end of the nozzle 601 is smaller than the radial dimension of the negative pressure chamber 6022, the foaming liquid inlet 6053 is connected to the negative pressure chamber 6022, the internal space of the foaming body 603 forms a foaming chamber 6031, a foaming core 604 is provided in the foaming chamber 6031, and the connecting device is provided with an air inlet 6052 connected to the foaming chamber 6031.

[0060] In this embodiment, the raw water inlet 6051 is connected to the second water outlet 103, and the air inlet 6052 is connected to the air outlet of the air supply device 50, such as... Figure 7As shown, during use, the nozzle 601 sprays water, creating a negative pressure in the negative pressure chamber 6022, thereby drawing the foaming liquid from the storage chamber A701 into the negative pressure chamber 6022, and allowing it to flow with the water to the foaming core 604; simultaneously, the air supply device 50 supplies air to the foaming chamber 6031, and the foaming mixture flowing through the foaming core 604 and the air complete the foaming operation, thereby forming foam, which is discharged from the foam outlet 6054. In other embodiments, the raw water inlet 6051 is connected to the air outlet of the air supply device 50, and the air inlet 6052 is connected to the second water outlet 103, as shown. Figure 8 As shown, the foaming liquid enters the foaming chamber 6031 along with the airflow under negative pressure, and the water flows into the foaming chamber 6031 through the air inlet 6052. The subsequent foaming process is the same as described above.

[0061] In this embodiment, the flow cross-sectional area at the outlet end of nozzle 601 is smaller than that at its inlet end, thereby compressing the fluid flowing through nozzle 601, increasing its flow velocity, and thus reducing the pressure on the fluid surface, thereby generating negative pressure in the negative pressure chamber 6022. Simultaneously, the negative pressure zone is mainly concentrated at the rear end of the nozzle 601 outlet end; therefore, the foaming liquid inlet 6053 is located at the rear end of the nozzle 601 outlet end, such as... Figure 5 As shown.

[0062] In this embodiment, the adapter includes a first connector 6021 and a second connector 6023 connected to each other. The first connector 6021 is provided with a negative pressure chamber 6022 and a foaming liquid inlet 6053 connected to the negative pressure chamber 6022. The second connector 6023 is provided with an air inlet 6052. A check valve 606 that opens in one direction along the foaming direction and the liquid inlet 6053 is provided between the first connector 6021 and the second connector 6023 and at the foaming liquid inlet 6053 to prevent fluid backflow.

[0063] In this embodiment, a first suction pump 901 and a flow sensor 110 are 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 outlet 103 and the raw water inlet 6051. When the flow sensor 110 detects water flow, the controller starts the air supply device 50 and the first suction pump 901. When the flow sensor 110 does not detect water flow, the controller shuts off the air supply device 50 and the first suction pump 901, realizing the automatic start and stop of the air supply device 50 and the first suction pump 901, and stabilizing the air intake and foaming liquid intake to stabilize the foaming effect. In other embodiments, the air inlet 6052 is used as the water inlet 101, and the flow sensor 110 is located between the second outlet 103 and the air inlet 6052, producing the same beneficial effects as described above.

[0064] This embodiment also includes a second liquid dispensing device, comprising a liquid storage chamber B702, a second suction pump 902 connected to the liquid storage chamber B702, and an actuation switch 100 for activating the second suction pump 902. The second suction pump 902 and the actuation switch 100 are electrically connected to the controller. The difference between the liquid storage chamber B702 and the liquid storage chamber A701 is that the liquid storage chamber A701 is used to hold foaming liquid for foaming, while the liquid storage chamber B702 is used to hold liquids that do not require foaming, meeting diverse user needs. Furthermore, the actuation switch 100 is an inductive switch, and the type of inductive switch includes, but is not limited to, laser, infrared, and capacitive sensing, enabling contactless liquid dispensing and improving the user experience.

[0065] In this embodiment, a housing 120 is also included. The housing 120 has an installation chamber 1201 and a storage chamber 1202. 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 located in the installation chamber 1201. The outlet 180 of the second liquid supply device, i.e., the outlet of the second suction pump 902, is located on the top wall of the storage chamber 1202. The actuation switch 100 is located around the outlet 180 to facilitate sensing user actions. The switching valve 80 has a switching switch that passes through the surface of the housing 120, or the surface of the housing 120 has a handwheel 130 that is driven to the switching switch. The top of the installation chamber 1201 has an inner box 140. The inner box 140 has several partitions, which divide the space of the inner box 140 into several spaces. Each space constitutes a battery box 703 for installing the power supply module 40, a liquid storage chamber A701, and a liquid storage chamber B702, respectively. The storage compartment 1202 makes full use of the remaining space in the box 120, providing convenience for users to temporarily store small items such as glasses and jewelry.

[0066] In this embodiment, a cover 150 and a foaming head 160 are also included. The cover 150 can be opened and closed to install the chamber 1201, preventing dust and moisture from entering the chamber. The foaming head 160 is connected to the foaming port 6054 of the foaming device 60, and the foaming head 160 can be magnetically attached to the box 120. Compared with the groove snap-fit ​​used in the prior art, the magnetic connection is more convenient to take out, and the box 120 is more aesthetically pleasing.

[0067] In this embodiment, a mixing valve 170 is also included, which has a hot water inlet, a cold water inlet and a mixed water outlet. The hot water inlet is connected to a hot water pipe, the cold water inlet is connected to a cold water pipe, and the mixed water outlet is connected to the inlet 101 of the switching device.

[0068] The shower device proposed in this embodiment is used as follows:

[0069] In the default state, switch 104 closes the second water outlet 103 and opens the first water outlet 102, allowing water to flow to the shower device and the user to begin showering. After showering, if shower gel or shampoo needs to be applied, press one end of switch 106. Switch 104 closes the first water outlet 102 and opens the second water outlet 103, allowing water to flow to the foaming device 60. At this time, flow sensor 110 detects the water flow, and the controller starts the air pump and the first suction pump 901. Foam is then sprayed out from the foaming head 160, completing the foaming process. The user can then apply the foam to their body or hair.

[0070] After application, press the other end of switch 106. Switch 104 closes the second water outlet 103 and opens the first water outlet 102. Flow sensor 110 does not detect water flow. The controller shuts off the air pump and the first suction pump 901, thus stopping foaming. Water then flows from the shower device, rinsing the foam clean.
