The electromagnetic valve extrudes the foaming piece 11 and the foaming element 12 to generate bubbles. The bubbles overflow from the overflow hole 13 to the first end face.

[0035] Specifically, the foaming element 12 can be an internal sponge, which is convenient for foaming the foaming element 12, and liquid consumables can be added in the sponge. A gel film can also be added outside the sponge and the liquid consumables, wherein the gel film is similar to a laundry gel bead, and the outer film melts after adding water. Further, the consumables can also be freeze-dried consumables, which expand after adding water.

[0036] In one embodiment of the present embodiment, the opening is arranged opposite to the first end face, the first end face is provided with an air hole 14 and a water inlet hole 15, the air hole 14 is communicated with the foaming cavity 10, and air enters the face cleaning instrument from the air hole 14; the water inlet hole 15 is communicated with the foaming cavity 10 and is used for foaming of the foaming element 12; the housing is provided with a feeding hole 16 and a piston in sealing connection with the feeding hole 16 at a position away from the opening, the feeding hole 16 is used for conveying the face cleaning product into the foaming cavity 10, and the piston is used for preventing overflow of bubbles from the feeding hole 16.

[0037] As shown in the drawings, Figure 2 In another embodiment of the present embodiment, the opening is arranged adjacent to the first end face, a one-way check valve is arranged in the overflow hole 13, the opening and the first end face and the cleaning cavity are matched in the same manner as described above, and details are not repeated here, when the reciprocating motion of the electromagnetic valve extrudes the foaming piece 11 and the foaming element 12, the one-way check valve arranged in the overflow hole 13 can prevent the backflow of bubbles in the overflow hole 13 from entering the housing, thereby avoiding malfunction of the face cleaning instrument.

[0038] Before use of the face cleaning instrument, the face cleaning product is sent into the foaming cavity 10 through the feeding hole 16, and water is sent onto the foaming element 12 through the water inlet hole 15, and the face cleaning instrument is turned on, at this time, the power supply unit supplies power to the electromagnetic valve, the electromagnetic valve is arranged vertically to the opening direction, and the foaming piece 11 can be continuously extruded according to the reciprocating motion of the electromagnetic valve, since one end of the foaming piece 11 abuts against the foaming element 12, the foaming piece 11 further extrudes the foaming element 12, so that the foaming piece 11 and the foaming element 12 also make reciprocating motion, in the reciprocating motion process, air enters from the air hole 14, and through the combined action of water, air and extrusion, the face cleaning product on the foaming element 12 is foamed, space occupation is saved, and the face cleaning instrument is more light, beautiful and elegant.

[0039] In a further embodiment of the present application, the electromagnetic valve comprises an iron rod 21, an iron sheet 22 and a copper coil 23 sleeved outside the iron rod 21, a first end of the iron rod 21 extends into the housing and is connected with the foaming piece 11, the iron sheet 22 is arranged in spaced apart relationship with the iron rod 21, the power supply unit supplies power to the copper coil 23 to magnetize the iron rod 21, and the iron rod 21 moves towards the iron sheet 22 after magnetization of the iron rod 21.

[0040] When the power supply unit supplies power to the solenoid valve, that is, the copper coil 23 is energized, the iron rod 21 is magnetized at this time, and under the action of the magnetic force, the iron rod 21 moves toward the direction of the iron sheet 22. Since the iron rod 21 is connected to the bubble part 11, and the bubble part 11 is in contact with the bubble element 12, the bubble part 11 and the bubble element 12 are driven to move away from the first end face in the direction perpendicular to the opening; when the power supply unit cuts off power to the solenoid valve, that is, the copper coil 23 is cut off, the iron rod 21 has no magnetic force at this time, and the iron rod 21 is away from the iron sheet 22. At this time, the bubble part 11 and the bubble element 12 move closer to the first end face in the direction perpendicular to the opening. During the reciprocating motion of the iron rod 21, the bubble part 11 and the bubble element 12 are also reciprocating, thereby causing the bubble element 12 to foam.

[0041] In a further embodiment of the present invention, the foaming part 11 is a flexible baffle. Optionally, the flexible baffle is a soft rubber vibration film. The flexible baffle is sealed with the foaming cavity, which can form a seal between the foaming part 11 and the foaming cavity 10 along the opening direction to prevent bubbles from overflowing from the opening, making the cleansing device safer to use and extending the service life of the cleansing device.

Figure 1 As shown, when the iron rod 21 is magnetized and moves toward the iron sheet 22, it compresses the elastic element 24. When the iron rod 21 is not magnetized, the elastic force of the elastic element 24 pulls the iron rod 21 away from the sheet, causing the iron rod 21 to reciprocate, thereby compressing the foaming part 11 and the foaming element 12 to achieve a foaming effect, making the foaming process of the cleansing device safer and more reliable. Optionally, the elastic element 24 is a spring.

[0043] Further references Figure 3 In a further embodiment of the present invention, an elastic element 24 is provided between the flexible baffle and the first end face. When the iron rod 21 reciprocates, it will continuously squeeze the flexible baffle, thereby squeezing the foaming element 12, causing the cleansing product on the foaming element 12 to foam.

[0044] In other embodiments of the present invention, the air hole 14 and the water inlet hole 15 are the same hole. Before the cleansing device is used, water first enters the cleaning chamber to allow the foaming element 12 to foam. During the use of the cleansing device, the reciprocating motion of the iron rod 21 continuously squeezes the foaming part 11 and the foaming element 12, allowing air to enter, thereby causing the cleansing product on the foaming element 12 to foam, making the cleansing device structure safe and reliable, and reducing the size of the cleansing device for easy carrying.

[0046] The power supply unit of the facial cleanser instrument supplies power to the copper coil 23, so that the iron bar 21 is magnetized; the magnetized iron bar 21 will squeeze the elastic element 24 and move the iron bar 21 to the direction of the iron sheet 22;

[0047] After the power supply unit stops supplying power to the copper coil 23, the iron bar 21 moves away from the iron sheet 22 under the action of the elastic element 24;

[0048] Due to the reciprocating motion of the iron bar 21, the iron bar 21 squeezes the foaming element 11 and the foaming element 12 to achieve the foaming effect.

[0049] In the present application, the power supply unit of the facial cleanser instrument supplies power to the electromagnetic valve, then the copper coil 23 is electrified and the iron bar 21 is magnetized, the iron bar 21 moves to the direction of the iron sheet 22 and squeezes the elastic element 24, when the power supply unit stops supplying power to the electromagnetic valve, the copper coil 23 is de-energized, the iron bar 21 is not magnetized, the iron bar 21 moves away from the iron sheet 22 under the action of the elastic force of the elastic element 24 and returns to the initial state, until the power supply unit supplies power to the electromagnetic valve again, the iron bar 21 reciprocates along the direction perpendicular to the opening and squeezes the foaming element 11 and the foaming element 12, so that the facial cleanser product on the foaming element 12 is foamed, the present application uses the principle of the electromagnetic valve to make the facial cleanser instrument foam, reduces the production cost, the electromagnetic valve occupies small volume and saves space, at the same time, the sealing of the foaming element 11 and the foaming cavity 10 can effectively prevent the foam from leaking out, and the use is safer.
