[0049] As a further implementation of the above technical solution: In this embodiment, there are three types of face wash heads: sponge head, soft brush head and metal head. The structures of face wash heads of different materials are different. The structures of the three types of face wash heads are further described below:

[0050] Attached Figure 3The sponge head structure schematic diagram, the sponge head includes a first surface cover 33, a sponge block 31, a pressure ring 34 and a first back cover 36. The first surface cover 33 is provided with a water outlet 32 ​​and a surface guide groove; the first back cover 36 is provided with a spiral first water inlet joint 37; the surface cover and the back cover are ultrasonically fixed together, and the water outlet of the first surface cover and the first water inlet joint are connected. The sponge block 31 is cylindrical, with a step at the bottom. The cylindrical part of the sponge is loaded into the annular pressure ring 34, and then the pressure ring is buckled and pressed on the first surface cover. The step part of the sponge is squeezed on the surface of the first surface cover, and the pressure ring is fixed to the first back cover with a screw buckle 35 structure; the bottom of the first back cover is provided with a step, which is convenient for hand pinching to disassemble and assemble the pressure ring. The middle area of ​​the first surface cover 33 is slightly higher than the periphery, the purpose is to raise the sponge block, slightly higher than the pressure ring, suitable for the contour of the bridge of the nose. The first silicone ring 37a is added to the threaded structure of the first water inlet joint, the purpose is to form a sealing structure when it is threaded with the handle.

[0051] Furthermore, water enters from the first water inlet joint, flows out through the water outlet of the first cover, and the surface guide groove diffuses the water to the sponge block. As for the material of the sponge block, the PVA sponge used in the sponge face wash is preferred. This type of sponge is soft, skin-friendly and has good water absorption, and can gently remove dirt and grease from the face. It should be noted that after washing your face with the sponge head, you need to squeeze out the water from the sponge head as much as possible so that the sponge can dry as soon as possible.

[0052] Attached Figure 4 The soft bristle brush head is a schematic diagram of the structure. The soft bristle brush head includes a soft bristle bundle 38 and a bottom shell 41. The soft bristle bundle is fastened by a metal fastener 39, and the tail ends are welded together, with a water outlet in the middle. A water inlet column 40 is arranged in the middle of the bottom shell 41, and a spiral second water inlet joint 42 is arranged on the back, and the water inlet column is connected to the water inlet joint. The lower part of the metal fastener 39 is glued and then embedded in the bottom shell 41 for fixing. The water inlet column 40 in the bottom shell extends into the water outlet of the soft bristle bundle 38, and the length of the water inlet column is about one third of the length of the soft bristle bundle. A second silicone ring 42a is added to the threaded structure of the second water inlet joint to form a sealing structure when it is threadedly connected with the handle.

[0053] Furthermore, water enters from the second water inlet joint, flows out to the soft hair bundle through the water outlet column of the bottom shell, and then flows out from the middle of the surface of the soft hair bundle. When the soft hair bundle moves and scrubs on the skin surface, it can spread the water. Regarding the material of the soft brush bristles, PBT bristles commonly used in facial cleansing brushes are used. The soft brush head can deeply clean the skin, but it is not suitable for all skin types. Use it with caution on sensitive skin. It should be noted that after washing your face with a soft brush head, you need to wipe the soft brush head as dry as possible so that the soft brush head can dry as soon as possible.

[0054] Attached Figure 5The schematic diagram of the metal head structure is shown in FIG. 4 . The metal head includes a metal stamping 43, a third face cover 44 and a third back cover 45. The surface of the metal stamping 43 is circular and has an arc, and the middle is slightly higher than the periphery. The surface is provided with dozens to hundreds of water outlet micropores 43a, and the aperture of the micropores is between 0.1 and 0.2 mm, and is made by laser punching technology. The third face cover 44 is provided with a water outlet hole, and the third back cover 45 is provided with a water inlet column. The face cover and the back cover are ultrasonically welded together. The metal stamping 43 is snap-fastened to the face cover. The third back cover 45 is provided with a spiral third water inlet joint 46, and a third silicone ring 46a is added to the threaded structure of the third water inlet joint to form a sealing structure when it is threadedly connected with the handle. The diameter of the metal head is about 35 to 40 mm.

[0055] Furthermore, water enters from the third water inlet joint, flows through the water inlet column of the third back cover to the water outlet of the third front cover, and then diffuses through the surface guide groove, and then forms water pressure in the narrow cavity formed by the inner surface of the metal stamping and the front cover, so that water is ejected from the micropores on the surface of the metal stamping to form many fine water columns. The designed ejection distance does not exceed 30 cm. If the ejection distance is too far, it is inconvenient to use, and it is easy to wet clothes or other objects during operation. The metal head can be washed close to the face, or it can be scrubbed with a sponge cover.

[0056] What needs further explanation is the sponge cover that comes with the metal head. The sponge cover is composed of a sponge layer and a cloth layer. The two layers are bonded or sewn together with sponge glue around the edges. A slit is processed in the middle of the cloth layer, and this slit is used to insert the metal head.

[0057] In this embodiment, the attached Figure 6 This is a schematic diagram of the electrical connection relationship in the base of this embodiment. The alternating current is connected through the power socket on the back of the base. A power drive board connected to the power socket is installed inside. The switch power supply step-down circuit located on the power drive board converts the alternating current into a low-voltage direct current voltage and supplies power to the control circuit. The control circuit is located on the touch button control board; the thyristor, the heating tube and the over-temperature protection switch are connected in series at both ends of the alternating current. The function of the thyristor is to adjust the power of the heating tube. The control circuit intelligently controls the conduction degree of the thyristor based on the water temperature at the outlet of the heating tube measured by the temperature sensor of the heating tube assembly, thereby adjusting the power of the heating tube to achieve the purpose of regulating the water temperature. The micro water pump, temperature sensor, and power drive board are electrically connected to the touch button control board. In order to improve the safety of the heating tube and avoid dry burning, the heating tube is used in combination with the over-temperature protection switch and the over-temperature protection switch is electrically connected in series between the AC power supply and the heating tube.

[0058] The principle of the utility model for saving water or electricity is as follows: the water output of the face washing head can be controlled by adjusting the aperture of the water inlet column of the water inlet of the base, and then cooperating with the software PWM method to control the rotation speed of the water pump. The aperture of the water inlet column is adjusted to about 1.2 mm. When the DC micro water pump of the selected model 130 is at the maximum rotation speed, the water output of the face washing head is about 0.6 liters / minute, which can meet the water output needs of the above three face washing heads; because the face washing head is directly and continuously scrubbing the face, the water almost passes through the face, and the water is fully utilized, so the water output of the face washing head does not need to be large; the maximum water output of a normal faucet is 6 to 10 liters / minute, and the water output is 3 to 5 liters / minute when half of the faucet is turned on. According to the face washing method of the background technology, to achieve the same face washing effect, the face washing time used is longer than that of the face washing device of the utility model, because the face washing head that discharges water is always scrubbing the face, which is more efficient. Obviously, the water-saving effect of the face washing device of the utility model is very obvious, so that using the instant heating face washing device in cold weather saves more electricity than washing the face with an instant hot faucet.
