[0002] The facial ultrasonic care device is a beauty instrument that uses ultrasonic technology for skin care. It acts on the deep layers of the skin through high-frequency ultrasonic vibrations to achieve effects such as cleaning, firming, lifting and nutrition introduction.

[0003] Facial ultrasonic care devices in the prior art usually need to be used with care media (gel and essence) and use ultrasonic treatment to improve skin care. However, in the actual treatment process, the care medium is usually applied to various parts of the face and moved along the face during the care operation. However, the face needs to be treated over a large area when applying, and it is impossible to quickly perform care treatment on each area in time after the treatment. Part of the applied medium slides and evaporates, resulting in care medium loss, which requires additional replenishment. Moreover, if the care treatment is not performed in time after application, the medium adheres to the face with a sticky texture, causing discomfort to the caregiver, and it is impossible to perform targeted and immediate application according to the position of the care probe, resulting in poor overall use effect. Summary of the invention

The magnetic ball is fixedly sleeved inside the hollow ball. One end of the push rod is fixedly connected to the fitting cover, and the other end is fixedly connected to the magnetic block. The fitting cover is located above the hollow ball and is magnetically connected to the magnetic ball. The hollow ball rolls in the arc opening. When the hollow ball moves upward in the inner cavity, the feeding assembly extrudes the coating medium through the gap between the arc opening and the hollow ball.

[0008] Preferably, the mounting shell is fixedly sleeved on the top of the bottom shell, the handle is fixedly sleeved on the top of the mounting shell, the piezoelectric wafer ring is fixedly sleeved inside the bottom shell, and the upper end sensing mechanism is nested in the handle and electrically connected to the connecting wire. The damping layer is located above the piezoelectric wafer ring, and the device control part is electrically connected to the connecting wire.

[0009] Preferably, the electromagnet is located in the inner cavity and fixed to the bottom of the handle. When the electromagnet is energized, it magnetically attracts the magnetic block. One end of the spring is fixedly connected to the limiting ring, and the other end is fixed to the bottom of the handle and sleeved outside the push rod. The limiting ring is fixedly sleeved on the outer surface of the push rod, and the heating tube is fixedly connected in the communicating ring cavity.

[0010] Preferably, the feeding assembly includes a sleeve, a rotating shaft, and a spiral blade. The sleeve is fixedly sleeved on the side of the mounting shell, and the inner end is fixedly connected to the outer side of the cylinder body and communicates with the communicating ring cavity. The rotating shaft is rotatably sleeved in the sleeve, and the spiral blade is fixedly connected to the outer side of the rotating shaft. A motor is provided at the outer end of the sleeve, and the output shaft of the motor is fixedly connected to the rotating shaft.

[0011] Preferably, the feeding port is vertically opened, the feeding assembly is horizontally installed on the mounting shell, the feeding port communicates with the top of the sleeve, and a sealing cover is detachably installed on the top of the feeding port.

[0012] Preferably, an assembly cavity is opened on the side of the mounting shell, the air supply pump is fixedly installed in the assembly cavity, the air supply pump communicates with the intermediate processing cylinder, a bypass mechanism is provided on one side of the intermediate processing cylinder, the bypass mechanism is conducted when the air pressure inside the inner cavity increases, a bypass hole is opened on the outer side surface of the mounting shell, and the bypass hole communicates with the inside of the mounting shell.

[0013] Preferably, the air outlet end of the air supply pump passes through the outer side surface of the cylinder body and communicates with the inner cavity.

The outer surface of the hollow ball absorbs the heat of the hot air flow in the inner cavity through the top groove.

[0015] A nursing method for a facial ultrasonic care device includes the following nursing steps:

[0016] Step 1: Before use, open the feeding port, pour the facial application medium for nursing into the feeding port, and fill it into the feeding assembly. Operate the device control unit to make the piezoelectric wafer ring generate ultrasonic waves.

[0017] Step 2: Hold the handle to make the nursing operation mechanism contact and approach the facial skin to be nursed. At the same time, start the dynamic sealing assembly to open a gap at the bottom of the dynamic sealing assembly, initially squeeze the application medium onto the face, and then make the bottom shell contact the face by squeezing the application medium.

[0018] Step 3: Push the nursing operation mechanism to move along the face. Under the pressure of the face, the bottom gap in the dynamic sealing assembly is opened passively. With the feeding assembly remaining started, during the movement of the bottom shell along the face, the bottom of the bottom shell always automatically extrudes the application medium onto the face, and cooperates with the ultrasonic waves of the piezoelectric wafer ring to act on the facial skin to complete the nursing treatment.

[0019] Step 4: Start the heating tube before nursing. As the feeding assembly continuously conveys the application medium, the application medium extruded from the bottom of the bottom shell has a certain amount of heat.

[0020] Step 5: During the facial care process, start the air supply pump. The air supply pump inputs air into the inner part of the intermediate treatment cylinder and heats the hollow ball in the dynamic sealing assembly. During the facial care process, the heated hollow ball moves along the face and performs hot compress and rolling massage through the hot application medium to complete the comprehensive care.

[0021] The beneficial effects of the present invention are as follows:

[0022] (1) By utilizing the cooperation of an intermediate processing cylinder, a dynamic sealing component, and a feeding component, the present invention extrudes and stores the facial application medium in the feeding component and inputs it into the internal diversion space of the intermediate processing cylinder. Before nursing, by controlling the dynamic sealing component to actively open the bottom gap, the application medium is actively and directionally applied to the facial care area. During the actual facial pressing and nursing process, the dynamic sealing component is passively extruded to open the bottom gap, enabling the application medium to be automatically extruded along the facial care, thereby avoiding premature full facial application, achieving automatic targeted application for the care area, and being able to achieve both prior directional active application and passive follow-up application along the position of the care operation mechanism during facial care, realizing various application processes of the application medium for nursing, reducing the discomfort of premature full application, applying instantaneously according to the care situation, and providing better comfort and convenience.

[0023] (2) By cooperating with the heating tube in the intermediate processing cylinder, when the feeding component is used to realize the extrusion and diversion of the application medium, the heating treatment of the application medium is completed, ensuring that the medium extruded subsequently is fully heated and warmed up. By using the heated application medium, gentle application is realized, further improving the absorption effect of the application medium and the adaptability of nursing, especially for winter nursing. Moreover, the diversion channel and the feeding component can store the application medium, and in cooperation with the automatic sealing at the bottom of the intermediate processing cylinder and the sealing treatment of the feeding port, effective storage of the application medium for nursing is achieved, eliminating the need for repeated feeding and further improving the comfort and convenience of facial application nursing.

[0024] (3) By once again utilizing the cooperation of the intermediate processing cylinder and the dynamic sealing component, during actual facial application and ultrasonic-assisted nursing, in cooperation with the hollow balls rolling along the face, the air supply pump is used to input air into the intermediate processing cylinder and heat it, enabling the hot air to act on the rolling hollow balls, causing the surfaces of the hollow balls to fully absorb heat, and continuously performing rolling hot compress and rolling massage on the face during the rolling process. During the process of cooperating with ultrasonic nursing, the heated rolling hollow balls are also used to complete facial massage nursing, comprehensively improving the nursing effect.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a facial ultrasonic care device and its care method, including an equipment control unit 1, a connection line 2, and a care operation mechanism. The care operation mechanism includes a grip 3, a mounting shell 4, a bottom shell 5, a damping layer 6, and a piezoelectric wafer ring 7. An intermediate processing cylinder 8 is fixedly sleeved inside the bottom shell 5. A dynamic sealing component 9 and a heating tube 10 are respectively arranged inside the intermediate processing cylinder 8. A feeding component 11 and an air supply pump 12 are respectively arranged on both sides of the mounting shell 4. A feeding port 15 is arranged at the top of the mounting shell 4 and is communicated with the feeding component 11. The intermediate processing cylinder 8 includes a cylinder body 81, an internal cavity 82, a communicating ring cavity 83, an arc-shaped opening 84, a communicating cavity 85, and a ring groove 86. The internal cavity 82 and the arc-shaped opening 84 are respectively opened at the upper and lower ends of the cylinder body 81 and are communicated with each other. The communicating ring cavity 83, the communicating cavity 85, the ring groove 86, and the arc-shaped opening 84 are all opened in the cylinder body 81 and are communicated in sequence. The dynamic sealing component 9 includes a push rod 91, an adapter cover 92, a hollow ball 93, a magnetic ball 94, a limiting ring 95, a spring 96, an electromagnet 97, and a magnetic block 98. The magnetic ball 94 is fixedly sleeved inside the hollow ball 93. One end of the push rod 91 is fixedly connected to the adapter cover 92, and the other end is fixedly connected to the magnetic block 98. The adapter cover 92 is located above the hollow ball 93 and is magnetically connected to the magnetic ball 94. The hollow ball 93 rolls in the arc-shaped opening 84. When the hollow ball 93 moves upward in the internal cavity 82, the feeding component 11 extrudes the coating medium through the gap between the arc-shaped opening 84 and the hollow ball 93.

[0036] Embodiment 1: Before use, open the sealing cover 16 on the feeding port 15, pour the facial application medium for nursing into the feeding port 15, and fill it into the sleeve 111 of the feeding assembly 11. Operate the equipment control unit 1 to energize the piezoelectric wafer ring 7 to generate ultrasonic waves. Hold the grip 3 so that the nursing operation mechanism contacts and approaches the facial skin to be nursed. At the same time, start the electromagnet 97 in the dynamic sealing assembly 9, generate magnetic suction force to adsorb the magnetic block 98, compress the spring 96, and the magnetic block 98 moves and drives the push rod 91 to move upward along the inside of the inner cavity 82, driving the adapter cover 92 to move upward, and driving the magnetic ball 94 in the hollow ball 93 magnetically attracted to the bottom of the adapter cover 92 to move upward. The magnetic ball 94 moves to open the arc opening 84, so that a gap is opened at the bottom of the dynamic sealing assembly 9. The spiral blade 113 in the feeding assembly 11 squeezes the application medium in the sleeve 111 into the communicating ring cavity 83, and after being heated by the heating tube 10, it is squeezed into the communicating cavity 85, and is extruded through the annular groove 86 and the arc opening 84, and is initially extruded onto the face. Subsequently, the bottom shell 5 contacts the face by squeezing the application medium, and pushes the nursing operation mechanism to move along the face. Under the pressure of the face, the hollow ball 93 in the dynamic sealing assembly 9 is resisted and is passively moved out of the arc opening 84, and the bottom gap is passively opened. As the feeding assembly 11 remains started, during the movement of the bottom shell 5 along the face, the arc opening 84 in the middle processing cylinder 8 at the bottom of the bottom shell 5 always automatically extrudes the application medium onto the face, and cooperates with the ultrasonic waves of the piezoelectric wafer ring 7 to act on the facial skin to complete the nursing treatment.

[0037] First of all, by using the cooperation of the middle processing cylinder 8, the dynamic sealing assembly 9 and the feeding assembly 11, the facial application medium is squeezed and stored in the feeding assembly 11 and input into the internal diversion space of the middle processing cylinder 8. Before nursing, the bottom gap is actively opened by controlling the dynamic sealing assembly 9 to achieve the active and directional application of the application medium to the facial nursing area. And during the actual facial pressing and nursing process, the dynamic sealing assembly 9 is passively squeezed to open the bottom gap, so that the application medium is automatically extruded when nursing along the face, thus avoiding the prior full application on the face, achieving automatic targeted application for the nursing area, and being able to achieve both prior directional and active application, and passive follow-up application along the position of the nursing operation mechanism during facial nursing, realizing various application treatments of the application medium for nursing, reducing the discomfort of prior full application, and applying immediately according to the nursing situation, providing better comfort and convenience.

[0038] In addition, in cooperation with the heating tube 10 in the intermediate processing cylinder 8, when the feeding assembly 11 is used to realize the extrusion and diversion of the coating medium, the heating treatment of the coating medium is completed, ensuring that the medium following the extrusion is fully heated and raised in temperature. By using the heated coating medium, gentle coating is realized, further improving the absorption effect of the coating medium and the adaptability of nursing, especially for winter nursing. Moreover, the diversion channel and the feeding assembly 11 can store the coating medium. With the automatic sealing at the bottom of the intermediate processing cylinder 8 and the sealing treatment of the feeding port 15, the effective storage of the coating medium for nursing is realized, eliminating the need for repeated feeding and further improving the comfort and convenience of facial coating nursing.

[0039] Embodiment 2: During the facial care process, the air supply pump 12 is started. The air supply pump 12 inputs air into the interior of the intermediate processing cylinder 8, fills the internal cavity 82 through the notch 99, and heats the hollow ball 93 in the dynamic sealing assembly 9 through the top groove 910 on the adapter cover 92. During the facial care process, the heated hollow ball 93 rolls along the face and performs hot compress and rolling massage through the hot coating medium to complete comprehensive care.

[0040] First of all, by making use of the cooperation between the intermediate processing cylinder 8 and the dynamic sealing assembly 9 again, during the actual facial coating and ultrasonic action nursing, in cooperation with the hollow ball 93 rolling along the face, the air supply pump 12 is used to input air into the intermediate processing cylinder 8 and heat it, so that the hot air acts on the rolling hollow ball 93, enabling the surface of the hollow ball 93 to fully absorb heat, and continuously performing rolling hot compress and rolling massage on the face during the rolling process. During the process of cooperating with ultrasonic nursing, the heated rolling hollow ball 93 is also used to complete facial massage nursing, comprehensively improving the nursing effect.

[0041] Among them, the installation shell 4 is fixedly sleeved on the top of the bottom shell 5, the handle 3 is fixedly sleeved on the top of the installation shell 4, the piezoelectric wafer ring 7 is fixedly sleeved inside the bottom shell 5, and the upper end electro-sensitive mechanism is nested in the handle 3 and electrically connected to the connecting wire 2. The damping layer 6 is located above the piezoelectric wafer ring 7, and the device control unit 1 is electrically connected to the connecting wire 2.

[0042] The piezoelectric wafer ring 7 is powered on and started through the electro-sensitive mechanism and the connecting wire, and generates ultrasonic action to complete the nursing operation. The damping layer 6 is located on the back of the wafer and is used to absorb the ultrasonic waves radiated backward by the wafer, reduce interference, and at the same time shorten the vibration time and improve the resolution.

[0043] Among them, the electromagnet 97 is located in the internal cavity 82 and fixed to the bottom of the handle 3. When the electromagnet 97 is powered on, it magnetically attracts the magnetic block 98. One end of the spring 96 is fixedly connected to the limiting ring 95, and the other end is fixed to the bottom of the handle 3 and sleeved outside the push rod 91. The limiting ring 95 is fixedly sleeved on the outer surface of the push rod 91, and the heating tube 10 is fixedly connected in the communicating ring cavity 83.

[0044] By utilizing the electromagnetic force generated when the electromagnet 97 is energized to actively adsorb the magnetic block 98, the push rod 91 is driven to move upward. Then, by using the adsorption effect between the adapter cover 92 at the bottom of the push rod 91 and the magnetic ball 94, the magnetic ball 94 is driven to move upward, and the arc-shaped opening 84 and the annular groove 86 are opened, realizing the extrusion and release of the coating medium to complete the coating. The heating tube 10 is located in the communicating annular cavity 83 to heat the internally extruded coating medium.

[0045] Among them, the feeding assembly 11 includes a sleeve 111, a rotating shaft 112, and a spiral blade 113. The sleeve 111 is fixedly sleeved on the side of the mounting shell 4, and its inner end is fixedly connected to the outer side of the cylinder body 81 and communicates with the communicating annular cavity 83. The rotating shaft 112 is rotatably sleeved in the cylinder body 81, and the spiral blade 113 is fixedly connected to the outer side of the rotating shaft 112. A motor is provided at the outer end of the sleeve 111, and the output shaft of the motor is fixedly connected to the rotating shaft 112. The feeding port 15 is vertically opened, and the feeding assembly 11 is horizontally installed on the mounting shell 4. The feeding port 15 communicates with the top of the sleeve 111, and a sealing cover 16 is detachably installed at the top of the feeding port 15.

[0046] The feeding assembly 11 completes the extrusion and pushing through the extrusion of the spiral blade 113 to achieve continuous discharging, and at the same time, storage can be realized in cooperation with the sealing cover 16.

[0047] Among them, an assembly cavity 14 is opened on the side of the mounting shell 4. The air supply pump 12 is fixedly installed in the assembly cavity 14. The air supply pump 12 communicates with the intermediate processing cylinder 8. A bypass mechanism is provided on one side of the intermediate processing cylinder 8, and the bypass mechanism is conducted when the air pressure in the internal cavity 82 increases. A bypass hole 17 is opened on the outer side of the mounting shell 4, and the bypass hole 17 communicates with the inside of the mounting shell 4. The air outlet end of the air supply pump 12 passes through the outer side of the cylinder body 81 and communicates with the internal cavity 82. The bypass mechanism includes a side pipe and a pressure valve 13. The side pipe is sleeved on the side of the cylinder body 81, and the two ends of the side pipe are respectively communicated with the internal cavity 82 and the inner cavity of the mounting shell 4. The pressure valve 13 is fixedly sleeved on the side pipe.

[0048] The air supply pump 12 supplies air and inputs it into the internal cavity 82, cooperating with the heating tube 10 to increase the temperature. On the one hand, it improves the heating treatment of the hollow ball 93. The pressure valve 13 actively discharges when there is internal stored air pressure, ensuring that the hollow ball 93 absorbs heat sufficiently while ensuring that the internal air pressure will not be too high to affect the magnetic attraction connection between the magnetic ball 94 and the adapter cover 92, and immediately discharging the excess air volume.

[0049] Among them, the dynamic sealing assembly 9 further includes a notch 99 and a top groove 910. The notch 99 is opened on the limiting ring 95, and the top groove 910 is opened on the outer side of the adapter cover 92. The outer surface of the hollow ball 93 absorbs the heat of the hot air flow in the internal cavity 82 through the top groove 910.

[0050] The internal cavity 82 is ensured to be fully conductive through the notch 99 and the top groove 910, ensuring the contact of the hot air with the hollow ball 93 and improving the contact heating effect.

[0051] A nursing method for a facial ultrasonic care device includes the following nursing steps:

[0052] First step: Before use, open the feeding port 15, pour the facial application medium for nursing into the feeding port 15, and fill it into the feeding component 11. Operate the device control unit 1 to make the piezoelectric wafer ring 7 generate ultrasonic waves.

[0053] Second step: Hold the handle 3 so that the nursing operation mechanism contacts and approaches the facial skin to be nursed. At the same time, start the dynamic sealing component 9, so that the bottom of the dynamic sealing component 9 opens a gap, and initially extrudes the application medium onto the face. Subsequently, make the bottom shell 5 contact the face by extruding the application medium.

[0054] Third step: Push the nursing operation mechanism to move along the face. Under the pressure of the face, the bottom gap in the dynamic sealing component 9 is opened passively. With the feeding component 11 remaining started, during the movement of the bottom shell 5 along the face, the bottom of the bottom shell 5 always automatically extrudes the application medium onto the face and cooperates with the ultrasonic waves of the piezoelectric wafer ring 7 to act on the facial skin to complete the nursing treatment.

[0055] Fourth step: Start the heating tube 10 before nursing. As the feeding component 11 continuously conveys the application medium, the application medium extruded from the bottom of the bottom shell 5 has a certain amount of heat.

[0056] Fifth step: During the facial care process, start the air supply pump 12. The air supply pump 12 inputs air into the interior of the intermediate processing cylinder 8 and heats the hollow ball 93 in the dynamic sealing component 9. During the facial care process, the heated hollow ball 93 rolls along the face and performs hot compress and rolling massage through the hot application medium to complete the comprehensive care.
