[0039] Embodiment 1

[0040] This embodiment is an explanation and description of a heated handheld facial cleansing device with a faucet water diverter.

[0041] Appendix Figure 1Schematic diagram of the overall structure of a heated handheld facial cleanser with a faucet water diverter, a handheld facial cleanser without a water tank, including a main body 1, a handle 2, a facial cleansing head 3 and a faucet water diverter 4. The facial cleansing head 3 is screwed to the top of the handle 2. There are two types of facial cleansing heads, a sponge head and a metal head. The faucet water diverter is a one-in-two-out water valve with a switching switch, which is a mature accessory for a faucet dental cleaner. The inlet is connected to the faucet, and there are two outlets. One is the normal water outlet 4b, and the other is the pressure-reducing water outlet 4a, which is used to connect to the facial cleanser. Because the water pressure and flow rate requirements of the facial cleanser are much smaller than the normal flow rate of the faucet, the pressure-reducing water outlet is a 1-cm-long threaded metal pipe with a diameter of about 1.5 mm, and a hose 5b is fixedly connected with a nut; during installation, the hose 5b is inserted into the metal pipe, and then the nut is rotated to fasten the hose. The second hose 5b enters the main body through the inlet hole 11 of the main body, and is fixed by an internal card slot and then connected to the inlet end of the micro electromagnetic water valve 7. The outlet end hose of the micro electromagnetic water valve is connected to the water inlet end of the heating tube assembly. The water outlet end of the heating tube assembly is connected to the handle through the main body outlet hole and then the hose 5a. The hose 5b connecting the faucet water diverter and the hose 5a connecting the handle are slightly different. The hose connecting the handle has a self-retractable characteristic so as to be stored in the storage bin of the main body. The wall-mounted rack 8 is used to place the handle.

[0042] The internal structure of the main body 2 is similar to that of an instant hot water dispenser without a water tank. The main body includes a housing, an AC power socket located at the lower part of the housing, an inlet hole and an outlet hole. The inlet hole is the inlet of the hose, which is used to transfer the hose from the outside of the main body to the inside; the outlet hole is the outlet of the hose, which is used to transfer the hose from the inside of the main body to the handle. A main body inner bracket 12 is arranged inside the main body. The instant hot heating tube assembly 6, the micro electromagnetic water valve 7, the power drive board 9 and the touch button control board 10 are fixed on the main body inner bracket 12. The inner bracket assembled with complete components is fixed in the internal card slot by being embedded from the bottom of the housing, and then the bottom cover is fixed to the bottom of the housing with a waterproof silicone ring.

[0043] Further, the main body is designed with a waterproof structure. Briefly describe the waterproof structure solution of the main body of the present utility model. Waterproof silicone sleeves are added to the AC power socket, the inlet hole and the outlet hole of the main body housing, and a waterproof silicone ring is added to the joint between the housing and the bottom cover. The top of the housing is silk-screened with touch button symbols, and touch buttons are used for convenient waterproof structure design.

[0044] Further, the heating tube assembly cooperates with the control circuit to realize the instant hot heating function. The present utility model preferably uses a rare earth thick film or a wound wire thick film instant hot heating tube. The instant hot heating tube assembly is an existing mature technology of an instant hot water dispenser and will not be elaborated here; because the maximum water temperature of the facial cleanser is only about 40 degrees, the over-temperature protection switch temperature protection point on the heating tube assembly is about 48 degrees, and the heating tube power can be designed to be about 1000W.

[0045] In this embodiment, attachedFigure 2 It is a schematic diagram of the handle structure of a handheld facial cleanser with a faucet water diverter. The handle includes a handle body 21, a bottom cover 25, a button 28, and a spiral interface component 23 at the top. The spiral interface component 23 includes an internal spiral interface, a through-hole water inlet column, a component silicone ring 23a, and a decorative piece 23b. The spiral interface component is assembled at the top of the handle. The internal spiral interface and the through-hole water inlet column are connected. The internal spiral interface is used to connect the facial cleansing head, and the through-hole water inlet column is used to connect the internal hose. The component silicone ring is used for sealing with the body to play a waterproof role. The decorative piece is buckled on the surface of the spiral interface component. The button 28 is made of silicone and is assembled on the body by the process of two-color injection molding.

[0046] Furthermore, an internal bracket is arranged inside the body. The internal bracket includes an inner front bracket 24a and an inner rear bracket 24b. The purpose of setting it is to facilitate the assembly of internal components. First, place the vibration motor 26 on the upper part of the inner rear bracket 24b, assemble the handle control board 30 welded with the battery negative electrode piece on the inner front bracket 24a, and then fix the inner front bracket 24a on the inner rear bracket with screws. In this way, the lower part of the combined internal bracket forms a battery compartment for accommodating AA or AAA dry batteries. Then, embed the assembled internal bracket component into the internal limit card slot from the lower end of the body and fix it.

[0047] Furthermore, the function of the vibration motor is to enable the facial cleansing head to have a sonic vibration effect. The sonic vibration can enhance the cleaning effect and at the same time have a certain massage effect. The purpose of placing the vibration motor at the top of the body is to make the vibration intensity of the facial cleansing head large and the vibration intensity at the hand-held part of the handle weak.

[0048] Furthermore, the bottom cover 25 includes a hose inlet hole, a bottom cover silicone ring 25a, and a battery cover 22. The battery cover 22 includes a battery positive electrode piece and a silicone ring. The battery cover is screwed on the bottom cover and is a detachable structure. According to the assembly sequence, after the internal bracket component is installed in the body, then assemble the bottom cover with a waterproof silicone ring at the bottom of the body. The bottom cover and the bottom of the body are fixed by snap connection.

[0049] Furthermore, the hose from the base enters the handle through the hose inlet hole of the bottom cover, and after being fixed by the card slot, it is connected to the through-hole water inlet column of the spiral interface component. The button, the vibration motor, the battery compartment are electrically connected to the handle control board.

[0050] Further explanation, the handle is designed with a waterproof structure. Here is a simple description of the waterproof structure solution of the present invention. The silicone button on the body is assembled on the body by the injection molding process. The spiral interface component is assembled on the top of the body with a silicone ring. The bottom cover is snap-fixed to the lower end of the body with a waterproof silicone ring. The battery cover is screwed on the bottom cover with a silicone ring.

[0051] In this embodiment, there are two types of face-washing heads: a sponge head and a metal head. The structures of the two face-washing heads are different. The structures of the two face-washing heads are described in detail below:

[0052] Attached Figure 3 is a schematic structural diagram of the sponge head. The sponge head includes a first face cover 33, a sponge block 31, a pressing ring 34 and a first rear cover 36. The first face cover 33 is provided with a water outlet hole 32 and a surface diversion groove; the first rear cover 36 is provided with a spiral first water inlet joint 37; the face cover and the rear cover are ultrasonically fixed together, and the water outlet hole of the first face cover communicates with the first water inlet joint.

[0053] Further, the sponge block 31 is cylindrical with a step at the bottom. The cylindrical part of the sponge is inserted into the annular pressing ring 34, and then the pressing ring is screwed onto the first face cover. The stepped part of the sponge is pressed against the surface of the first face cover; the cylindrical part of the sponge protrudes about 5-10 millimeters from the surface of the pressing ring. The purpose of the protrusion is to adapt to the contour of the nose on the face; the pressing ring is fixed to the first rear cover by a snap-fastening 35 structure, and the number of snap-fastening is 2-4. There is a step at the bottom of the first rear cover to facilitate pinching by hand to disassemble and assemble the pressing ring and replace the sponge. A first silicone ring 37a is added to the threaded structure of the first water inlet joint to form a sealing structure when threadedly connected to the handle.

[0054] Further, water enters from the first water inlet joint and flows out through the water outlet hole of the first face cover. The surface diversion groove diffuses the water onto the sponge block. The sponge block is preferably a PVA sponge used for a sponge face wash. This type of sponge is soft and skin-friendly and has good water absorption. It should be noted that after each face wash with the sponge head, the water in the sponge head needs to be squeezed out as much as possible so that the sponge can dry quickly.

[0055] Attached Figure 4 is a schematic structural diagram of the metal head. The metal head includes a metal stamping part 38, a second face cover 39 and a second rear cover 40; the surface of the metal stamping part 38 is circular and has a certain curvature, slightly higher in the middle than the periphery, and dozens to more than a hundred micropores 38a are processed on its surface by laser drilling. The aperture of the micropores is between 0.1 and 0.2 millimeters. The second face cover 39 is provided with a water outlet hole, and the second rear cover 40 is provided with a water inlet column. The face cover and the rear cover are ultrasonically welded together; the metal stamping part 38 is snap-fastened to the face cover. The second rear cover is provided with a spiral second water inlet joint 41, and a second silicone ring 41a is added to the threaded structure of the second water inlet joint to form a sealing structure when threadedly connected to the handle. The diameter of the metal head is about 35-40 millimeters, and its surface is electroplated with skin-friendly titanium or gold.

[0056] Further, water enters through the second water inlet joint, flows through the water inlet column of the second rear cover to the water outlet holes of the second face cover, and then diffuses through the surface diversion. A water pressure is formed in the narrow cavity formed by the inner surface of the metal stamping part and the face cover, causing the water to spray out from the micropores on the surface of the metal stamping part, forming many fine water columns. The designed spraying distance does not exceed 30 cm. If the spraying distance is too far, it is not convenient to use and it is easy to wet clothes or other objects during operation. The metal head can be close to the face for rinsing or can be covered with a sponge sleeve for scrubbing.

[0057] It should be further noted that the sponge sleeve equipped with the metal head is composed of a sponge layer and a cloth layer. The two layers are bonded or sewn together with sponge glue around the perimeter. A slit is processed in the middle of the cloth layer, and this slit is used to insert the metal head.

[0058] In this embodiment, Figure 5 This is the electrical connection schematic diagram of the main unit 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 switching power supply buck circuit located on the power drive board converts the alternating current into a low-voltage direct current voltage to supply power to the control circuit, and 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 across the two ends of the alternating current. The function of the thyristor is to adjust the power of the heating tube, and the control circuit intelligently controls the conduction degree of the thyristor according to the water temperature measured by the temperature sensor at the water outlet of the heating tube. The electromagnetic water valve, the temperature sensor and the power drive board are electrically connected to the touch button control board. In order to improve the use 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 power circuit board and the heating tube.

[0059] As a further explanation of the above technical solution, the path of water in this embodiment is as follows: Water flows from the faucet through the faucet water divider to the hose, and then enters the micro electromagnetic water valve inside the main unit by relying on the water pressure inside the water pipe, then flows to the heating tube assembly, flows through the hose to the through-hole water inlet column inside the handle, and finally flows into the inside of the face washing head and then flows out from the surface of the face washing head; the micro electromagnetic water valve is used to control the on-off of the water path, and the electromagnetic water valve opens when the face washing instrument is turned on.

[0060] The principle of water output control in this embodiment is further explained as follows: It is controlled by adjusting the aperture of the pressure-reducing water outlet of the faucet water divider to ensure that the flow rate requirements of the face washing instrument can be met even when the faucet is opened at the maximum or half flow rate. According to the test results, the flow rate requirement of the face washing instrument in this embodiment is about 0.4 - 0.6 liters per minute, while the maximum flow rate of the faucet is usually 6 - 10 liters per minute, so a pressure-reducing water outlet is needed to reduce the flow rate; on the other hand, the small flow rate requirement of the face washing instrument can greatly save water. The efficient face washing method of continuously flushing the face with the face washing head that sprays water makes full use of the water, and can save water compared with the direct water connection method using the faucet described in the background technology.

[0061] Example 2

[0062] This example is an explanation and description of a non-heated handheld facial cleanser with a faucet water diverter.

[0063] The difference from Example 1 is that because of the lack of a heating function, there is no main body part in Example 1. The faucet water diverter connector is directly connected to the handle by a hose, and the handle structure is the same as that in Example 1.

[0064] Reference attachment Figure 6 FIG. is a schematic diagram of the overall structure of a non-heated handheld facial cleanser with a faucet water diverter. The handheld facial cleanser without a water tank includes a handle 2, a facial cleansing head 3, and a faucet water diverter 4. The facial cleansing head 3 is screwed onto the top of the handle 2. The facial cleansing head has two types: a sponge head and a metal head.

[0065] Further, the water path in this example is as follows: Switch the faucet water diverter to the reduced-pressure water outlet, turn on the faucet switch, and rely on the water pressure in the water pipe. Water flows from the external hose to the hose inside the handle and then out of the facial cleansing head.

[0066] Example 3

[0067] This example is an explanation and description of a handheld facial cleanser with a hose connector.

[0068] Different from the above Examples 1 and 2, this example does not use a faucet water diverter connector but a hose connector. In Examples 1 and 2, water flows from the faucet to the facial cleansing head by the water pressure in the water pipe. In this example, there is no faucet, so the facial cleanser will use a micro direct-current water pump to make water flow to the facial cleansing head.

[0069] Reference attachment Figure 7 FIG. is a schematic diagram of the overall structure of a handheld facial cleanser with a hose connector. The handheld facial cleanser without a water tank includes a handle 2, a facial cleansing head 3, and a hose connector 15. The facial cleansing head 3 is screwed onto the top of the handle 2. The facial cleansing head has two types: a sponge head and a metal head.

[0070] Furthermore, the hose connector 15 includes a fixing block 15a, a fixing cap 15b and a spiral joint 15c; one end of the hose connector is a fixing block, and the fixing block includes a shell and an internal water inlet column. The hose 15d is inserted from the hole of the upper cover of the shell, and then the hose is inserted into the water inlet column and fixed, and finally the upper cover is buckled and fixed to the bottom cover; when the hose is placed in the container, the fixing block plays the role of sinking the hose to the bottom. The other end of the hose connector is a spiral joint 15c, which is an external spiral structure of a through hole, which is convenient for spiral connection with the water inlet interface of the handle; the hose is inserted into the spiral joint and fixed by the fixing nut 15b. The hose length of the hose connector is about 60 cm. The spiral joint of the hose connector is spirally connected to the water inlet interface 20 of the handle.

[0071] The handle of this embodiment is quite different from the handle of Embodiment 1. Figure 8 Schematic diagram of the handle structure of a handheld facial cleanser with a hose connector, the handle includes a handle body 21, a bottom cover 25, a button 28 and a spiral interface component 23 at the top; the spiral interface component 23 includes an inner spiral interface and a through-hole water inlet column, a component silicone ring 23a and a decorative piece 23b, and the spiral interface component is assembled on the top of the handle. The inner spiral interface and the through-hole water inlet column are connected, the inner spiral interface is used to connect the facial cleanser head, and the through-hole water inlet column is used to connect the internal hose 1; the component silicone ring is used to seal with the body to play a waterproof role, and the decorative piece 23b is buckled on the surface of the spiral interface component 23. The button 28 is made of silicone and is assembled on the body using a two-color injection molding process.

[0072] Furthermore, an inner bracket is provided inside the fuselage, and the inner bracket includes an inner bracket front frame 24a and an inner bracket rear frame 24b, and the purpose of the provision is to facilitate the assembly of internal parts; first, the rechargeable battery 27 and the micro water pump 19 are placed in the inner bracket rear frame 24b, and the handle control panel 30 is assembled on the inner bracket front frame 24a, and then the inner bracket front frame 24a is fixed to the inner bracket rear frame 24b with screws, so that the front and rear brackets are combined to fix the rechargeable battery 27 and the micro water pump 19, and then the micro vibration motor 26 is fixed to the top of the inner bracket; finally, the assembled complete inner bracket assembly is embedded into the internal limit slot from the lower end of the fuselage and fixed.

[0073] Further, the bottom cover 25 includes a water inlet interface 20, a bottom cover silicone ring 25a, a charging socket 29, and a socket rubber plug 29a; the water inlet interface includes an internal spiral interface and a connected water outlet column. The internal spiral interface is used to connect to a hose connector, and the water outlet column is used to connect to an internal hose. The main body of the charging socket is fixed inside a groove on the inner side of the bottom cover and sealed with glue; the socket rubber plug includes a tail and a main body. The tail is fixed on the bottom cover, and the main body of the rubber plug can be inserted into the jack of the charging socket. When charging is required, the main body of the rubber plug is pulled out. According to the assembly steps, after the assembled inner bracket assembly is installed into the fuselage, the bottom cover with a waterproof silicone ring is then assembled at the bottom of the fuselage, and the bottom cover is fixedly connected to the bottom of the fuselage by a buckle.

[0074] For further explanation, the hose connector is connected to the water inlet interface of the handle bottom cover. One end of the internal hose inside the handle is connected to the water outlet column, and the other end is connected to the inlet end of the micro water pump. The outlet end hose is connected to the water inlet column of the through hole of the spiral interface assembly. The button, vibration motor, micro water pump, rechargeable battery, and charging socket are electrically connected to the handle control board.

[0075] The water flow control principle of this embodiment is further described as follows: it is achieved by adjusting the aperture of the water inlet column of the hose connector fixing block and controlling the rotation speed of the micro water pump by the control board.

[0076] The benefits of this embodiment are: the whole product is made small and convenient to carry. When in use, only the fixing block of the hose connector needs to be placed in a water-containing container, which can be a mineral water bottle, a washbasin, etc.
