Description

FIELD OF INVENTION

[0001] The present invention relates to skincare dispensing devices and physiotherapy devices. More particularly, the invention relates to an integrated skincare dispensing and physiotherapy device comprising a skincare container with a pump for dispensing skincare product, and a ring-shaped physiotherapy device surrounding the pump.BACKGROUND

[0002] Skincare product containers are commonly used to store and dispense topical compositions such as creams, lotions, serums, and essences. To enhance the absorption and efficacy of skincare products, various therapy devices have been developed that provide stimulation to the skin, including phototherapy, microcurrent stimulation, vibration, and heating.

[0003] Some approaches have combined skincare containers with therapy devices by attaching a therapy device to the container cap or body. For example, cosmetic containers with skin booster caps have been proposed that provide electrical stimulation, light irradiation, and vibration to the user's skin. Similarly, cosmetic containers with applicators that deliver current or vibration while applying contents to the user's body have been developed.

[0004] However, in many existing configurations, the therapy device blocks the dispensing outlet of the container, requiring the user to remove the therapy device before dispensing the skincare product. This separation and reattachment process is inconvenient and interrupts the user's skincare routine.

[0005] Furthermore, existing devices typically provide stimulation elements only on the therapy device itself, without providing stimulation elements on the pump or dispensing component. This limits the ability to apply physiological stimulation to the skin simultaneously with product dispensing.

[0006] Additionally, when therapy devices are positioned around or adjacent to dispensing components, the skin may inadvertently contact the dispensing components during therapy application. This interference between the skin and dispensing components can cause clumsy and unsmooth therapy operation, reducing the effectiveness of the treatment.

[0007] Some therapy devices have been proposed that can be stored in a retracted position and moved to an extended position for use. However, these devices do not address the need to separate dispensing and therapy functions by providing distinct positions where the therapy surface is at different heights relative to the dispensing end.

[0008] There remains a need for an integrated skincare dispensing and physiotherapy device that allows convenient dispensing without removing the therapy device, provides stimulation elements on both the therapy device and the pump with electrical connection therebetween, and enables positional movement of the therapy device to separate dispensing and therapy functions while preventing interference between the skin and dispensing components during therapy.OBJECTS OF THE INVENTION

[0009] Some objects of the invention are as follows:

[0010] An object of the present invention is to provide an integrated skincare dispensing and physiotherapy device comprising a skincare container with a pump and a ring-shaped physiotherapy device surrounding the pump, wherein the physiotherapy device includes a first stimulation element and the pump includes a second stimulation element for applying physiological stimulation to the skin.

[0011] Another object of the present invention is to provide a skincare therapy device wherein the physiotherapy device is movable relative to the bottle cap between a first position and a second position, wherein in the first position the therapy surface is at a height equal to or lower than the pressing head to enable dispensing, and in the second position the therapy surface is at a height greater than the pressing head to enable therapy application without interference from the dispensing components.

[0012] Another object of the present invention is to provide an electrical connection between the pump and the physiotherapy device so that electrical power and control signals are transmitted from the physiotherapy device to the second stimulation element in the pump.

[0013] An object of the present invention is to provide a guide structure on the bottle cap comprising a guide sleeve with first and second positioning grooves spaced along the first axis, and a positioning strip on the physiotherapy device to lock the physiotherapy device in the first position or the second position.

[0014] An object of the present invention is to enable the physiotherapy device to be detachably mounted to the bottle cap for independent use, cleaning, charging, or replacement.

[0015] An object of the present invention is to provide an occlusion cover with a plugging bulge that seals the liquid outlet and protects the stimulation elements from contamination during storage or transport.

[0016] An object of the present invention is to incorporate a heating element thermally coupled to the pressing head to preheat the dispensed product to a comfortable temperature prior to application.

[0017] An object of the present invention is to provide temperature control with a temperature sensor and a safety cutoff to prevent overheating of the product or skin.

[0018] An object of the present invention is to incorporate phototherapy light-emitting units and microcurrent electrodes on the physiotherapy device for delivering optical therapy and electrotherapy simultaneously or independently.

[0019] An object of the present invention is to provide a pressing notch on the side wall of the physiotherapy device through which the pressing elementis exposed, allowing the user to apply pressing force from the side.

[0020] An object of the present invention is to provide sliding conductive contacts or pogo-pin electrodes for establishing the electrical connection between the pump and the physiotherapy device.

[0062] In an embodiment, the phototherapy unit emits multiple therapeutic wavelengths adapted for skin care and dermatological treatment. Red light (approximately 630–660 nm) penetrates deeply into the skin to stimulate blood circulation, enhance collagen production, and promote skin regeneration and repair. Blue light (around 415–470 nm) exhibits antibacterial properties and is effective in treating acne, minimizing breakouts, and reducing inflammation. Green light (approximately 520–540 nm) helps reduce hyperpigmentation, even skin tone, and soothe sensitive or irritated skin. Yellow light (around 580–600 nm) improves cellular oxygen exchange, enhances lymphatic circulation, and supports detoxification and skin revitalization. Near-infrared light (800–850 nm) penetrates deeper tissue layers to accelerate healing, reduce pain, and alleviate inflammation, thereby supporting overall skin recovery and rejuvenation.BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS

[0082] The terms "a" and "an" herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. The terms "having", "comprising", "including", and variations thereof signify the presence of a component.

[0083] Embodiments of the present invention disclose an integrated skincare dispensing and physiotherapy device that combines a topical product container with a therapy module. The device addresses the need for convenient dispensing of skincare products while simultaneously providing physiological stimulation to enhance product absorption and skin treatment.

[0084] In an embodiment of the invention, the skincare therapy device comprises a bottle cap configured to be attached to a skincare product container, a pump mounted in the bottle cap and having a pump core movable along a vertical first axis with a dispensing end for discharging skincare product, and a physiotherapy device arranged along an outer periphery of the pump. The physiotherapy device comprises a first stimulation element, and the pump further comprises a second stimulation element configured to apply physiological stimulation to a skin surface while the skincare product is dispensed through the dispensing end.

[0085] In some embodiments, an electrical connection may be established between the pump and the physiotherapy device to permit transmission of electrical power and / or control signals to the second stimulation element. Structural implementations of such electrical connections are described in later embodiments.

[0086] In accordance with another aspect, the physiotherapy device is movable relative to the bottle cap between at least two axial positions to selectively enable dispensing and therapy modes. Detailed structural embodiments of such positional movement are described below.

[0087] The physiotherapy device may be ring-shaped and coaxially arranged with respect to the pump. The physiotherapy device may comprise a battery and a control circuit configured to drive both the first stimulation element and the second stimulation element. The pump and the physiotherapy device may be detachably connectable to one another, enabling independent use, cleaning, charging, or replacement of the physiotherapy device.

[0088] In another embodiment of invention, a method is provided for operating the skincare therapy device comprises moving the physiotherapy device relative to the bottle cap from a first position to a second position along a first axis, dispensing a skincare product from the pump in the first position, and applying physiological stimulation to a skin surface using the first stimulation element of the physiotherapy device in the second position. The method may further comprise applying a second stimulation from the second stimulation element in the pump when in the first position, with an electrical connection between the pump and the physiotherapy device established in the first position to power the second stimulation element.

[0089] In certain embodiments, the first stimulation element may include cooling, vibrational, ion therapy, or EMS modules to enhance therapeutic effect.

[0090] Embodiments of the present invention will now be described in detail with reference to FIGS. 1 to 17, wherein like reference numerals refer to like elements throughout.

[0091] In an embodiment, a skincare dispensing and physiotherapy device is provided, comprising a skincare container 100 and a physiotherapy device 116. The skincare container 100 is configured to hold and pump out skin care compositions such as eye cream, face cream, lotion, essence, facial cleanser, or their combinations. This combination provides users with an integrated solution that stores topical products and a device that enhances product delivery and skin stimulation.

[0092] In an embodiment, the skincare container 100 employs a pump 106 to dispense the product contained therein. The skincare container 100 includes a bottle body 102, a bottle cap 104, and a pump 106. The bottle body 102 defines a reservoir for the skin care product, and the bottle cap 104 is engaged with the bottle body 102 and defines an installation channel 180 that connects the interior of the bottle body 102 with the exterior. The pump 106 is mounted in the installation channel 180. The pump 106 includes a pressing head 108 disposed outside the bottle cap 104 and movable relative to the bottle cap 104 in a reciprocating manner, and the pressing head 108 defines a liquid outlet 110 in fluid communication with the interior of the bottle body 102. The pressing head 108 may also be referred to as the dispensing end or pressing end of the pump 106. This arrangement provides a familiar, hygienic dispensing interface compatible with a wide range of topical liquids and emulsions.

[0093] In an embodiment, the bottle body 102 may be configured as a refillable design, allowing the user to refill the skincare product without replacing the entire container. The control board 166 may implement an energy-efficient standby mode that minimizes power consumption when the device is not in active use.

[0094] In an embodiment, the bottle cap 104 may be a ring-shaped mount that fastens to the bottle body 102. The installation channel 180 as a through-hole in the base provides an axial path between the bottle body 102, the interior, and the outside. The pump 106 may be facilitating in discharging liquid, gas, or mixtures without restriction from the skincare container 100 by application of compressive force. The pump 106 may include a pressing head 108, a piston, a spring, a suction tube, and at least one check valve. When the pressing head 108 is not depressed or pressed, the liquid in the skincare container 100 remains stationary, and the pump cavity is in pressure equilibrium with the liquid present in the container. On pressing the pressing head 108 compresses the piston and spring, thereby reducing pump cavity volume and increasing the cavity pressure. This pressure drives liquid out of the liquid outlet 110 while the internal check valve prevents backflow. On release, the spring returns the piston toward its original position, increasing the pump cavity volume and lowering the internal pressure so that liquid is drawn into the pump cavity through the suction tube, with the suction-end check valve ensuring one-way flow.

[0095] In an embodiment, the liquid dispensing component may include alternatives such as an automatic suction pump, a liquid dispensing dropper, or a liquid dispensing piston cylinder, without limiting it. Liquid may be dispensed by manual pressing, electric suction, or manual suction. The automatic suction pump requires no manual force, has a built-in micro motor and suction structure, and automatically creates a negative pressure after being powered on, achieving automatic liquid dispensing. The liquid dispensing dropper consists of a dropper head and a dropper body, where manually squeezing and releasing the dropper head creates a negative pressure, drawing the liquid from the container into the dropper body. The liquid-dispensing piston cylinder is similar in structure to a simple syringe, including a cylinder body, a piston, and a plunger, where pushing the plunger expels air from the cylinder and pulling the plunger uses negative pressure to draw out the liquid.

[0096] In an embodiment, the pump 106 may provide metered dispensing configured to dispense a predetermined amount of skincare product per press, such as 0.1 ml, 0.2 ml, or 0.5 ml, without limiting to it. The pump 106 may employ airless pump technology to prevent oxidation of the skincare product and maintain product freshness. The bottle body 102 may include a visual indicator showing the remaining product level, such as a transparent window or graduated markings. The pump 106 may include an anti-drip valve to prevent leakage after dispensing.

[0097] In an embodiment, the physiotherapy device 116 is ring-shaped and is arranged concentrically around the pressing head 108 so that the liquid outlet 110 remains exposed outside the physiotherapy device 116. In certain embodiments, the physiotherapy device 116 may be fixed relative to the bottle body 102. In alternative embodiments, the physiotherapy device 116 may be movable relative to the bottle cap. When the pressing head 108 is depressed, the physiotherapy device 116 is retained in its position relative to the bottle body 102, and the user may dispense product without removing the physiotherapy device 116. As the liquid outlet 110 is unobstructed by the physiotherapy device 116, users can access the dispensed product conveniently. Positioning the physiotherapy device 116 around the pressing head 108 also provides practical storage for the device and reduces the chance of misplacement while keeping the kit compact.

[0098] In an embodiment, the physiotherapy device 116 is also configured to be removable from the bottle body 102 and the bottle cap 104 so that it can be used independently from the skincare container 100. The ability to separate the physiotherapy device 116 from the skincare container 100 preserves the versatility of use and cleaning, replaceability, and enables independent charging or maintenance of the device.

[0099] In an embodiment, the therapy surface may be removable and replaceable for improved hygiene. The physiotherapy device 116 may have a water-resistant rating, such as IPX4 for splash resistance or IPX5 for water jet resistance, without limiting to it. The physiotherapy device 116 may include a self-cleaning mode using UV-C light to sanitize the therapy surface. A cleaning indicator may be provided to remind the user when cleaning is recommended based on usage time or number of uses.

[0100] In an embodiment, the physiotherapy device 116 is attached to the bottle cap 104. The physiotherapy device 116 simply overlies the top face of the bottle cap 104, in alternative embodiment magnet fasteners are provided between the physiotherapy device 116 and the bottle cap 104 to realize magnetic retention, a snap feature for example, a convex snap on one component and a corresponding slot on the other is used to mechanically clip the physiotherapy device 116 to the bottle cap 104. These selectable retention mechanisms provide reliable positioning while permitting intentional detachment when required.

[0101] In an embodiment, the physiotherapy device 116 may support interchangeable therapy heads configured for different treatment areas, such as a face therapy head, an eye therapy head, and a neck therapy head. The pump 106 may support replaceable pump cartridges for different skincare products, enabling the user to switch between products without replacing the entire bottle body 102. A modular battery pack may be provided for extended use, allowing the user to swap battery packs for continuous operation.

[0102] In an embodiment, the physiotherapy device 116 may be formed as a single unit or detachable from joining an upper shell 132 and a lower shell 148. The upper shell 132 includes a roof plate 134 and an inner baffle 138 on the interior side of the roof plate 134. The lower shell 148 includes a base plate 150 and an outer baffle 156 disposed outside the base plate 150. The roof plate 134 and base plate 150 are arranged to face one another, and the inner baffle 138 and outer baffle 156 are likewise opposed so that, together, the roof plate 134, inner baffle 138, base plate 150, and outer baffle 156 may form an enclosed storage space. Electronic components, including a battery164 and a control board 166, are housed within this storage space and may be electrically connected to the first stimulation element 170. Other stimulation elements may also be located within the storage space. Housing the electronics and optics within the shells provides a protected, compact module suitable for repeated topical application.

[0103] In an embodiment, the physiotherapy device 116 may support wireless or inductive charging capability, eliminating the need for a physical charging port and improving water resistance. A solar charging panel may be integrated into the outer surface of the physiotherapy device 116 for eco-friendly charging. The charging port 168 may be a USB-C port supporting fast charging capability, such as achieving 80% charge in approximately 30 minutes, without being limited to it. A battery level indicator may be provided as LED indicators on the physiotherapy device 116 or displayed in the companion app.

[0104] In an embodiment, the upper shell 132 further comprises a mating plate 142 integrally connected to the outer side of the roof plate 134. The mating plate 142 cooperates with the outer baffle 156 through a circumferential concave-convex interlocking configuration. Specifically, the mating plate 142 is provided with a plurality of concave parts 144 and convex parts 146 alternately arranged along the circumferential direction to form a continuous concave-convex engagement profile. Correspondingly, the outer baffle 156 is formed with alternating pits and protrusions along its circumference. Each concave part 144 is configured to be inserted into a corresponding pit of the outer baffle 156, thereby establishing a complementary interfit structure. Through this cooperative engagement, the mating plate 142 and the outer baffle 156 together form a closed annular assembly with enhanced structural integrity and positional stability.

[0105] In an embodiment, the outer peripheral surface of the physiotherapy device 116 may include a textured grip surface for secure handling during use. The therapy surface may be contoured to match facial contours for improved contact and treatment efficacy. The physiotherapy device 116 may have a lightweight design, such as less than 150 grams, without limiting to it, for comfortable extended use. The device may be configured for one-handed operation, allowing the user to dispense and apply therapy with a single hand.

[0106] In an embodiment, by employing the concave-convex interlocking configuration, accurate circumferential positioning is achieved during assembly, while simultaneously restricting undesired relative displacement between the mating plate 142 and the outer baffle 156. Furthermore, when the mating plate 142 and the outer baffle 156 are manufactured in distinct colors or surface finishes, the interlocked regions may produce differentiated visual effects, thereby enhancing aesthetic versatility and enabling design customization without altering functional performance.

[0107] In an embodiment, to reinforce the structural strength of the convex parts 146, a stiffener 172 is provided on the inner side corresponding to each convex part 146. The stiffener 172 improves resistance against bending or deformation under mechanical stress and ensures reliable engagement between the mating plate 142 and the outer baffle 156 during long-term use.

[0108] In an embodiment, the lower end of each stiffener 172 protrudes downward beyond the lower end of the corresponding convex part 146. The base plate 150 is provided on its upper surface with a plurality of positioning slots 152. The lower end of each stiffener 172 is insertable into the positioning slots 152, thereby achieving precise axial positioning during assembly and effectively preventing unintended rotational or lateral movement of the mating plate 142. This arrangement enhances assembly reliability and mechanical robustness.

[0109] In alternative embodiments, stiffening ribs may additionally or alternatively be formed on the inner side of the convex portions of the outer baffle 156, thereby further strengthening the overall annular structure while maintaining the same functional principle.

[0110] In an embodiment, the lower shell 148 further includes a connecting plate 158 disposed on the inner side of the base plate 150. The connecting plate 158 is annular in configuration. The limiting groove 160 is formed along the inner circumference of the connecting plate 158, while a corresponding limiting protrusion 140 is formed along the outer circumference of the inner baffle 138. The connecting plate 158 is arranged around the outer periphery of the inner baffle 138 such that the limiting groove 160 engages with the limiting protrusion 140 in a snap-fit manner. This cooperative engagement prevents separation of the connecting plate 158 relative to the inner baffle 138 and ensures stable structural integration of the upper shell 132 and lower shell 148.

[0111] In an embodiment, the limiting groove 160 and the limiting protrusion 140 may extend circumferentially along the lower shell 148 and may be provided in multiple segments distributed around the circumference, thereby enhancing circumferential locking strength and load distribution.

[0112] In an embodiment, the base plate 150 is provided with a support structure 154. The support structure 154 abuts against and supports the lower surface of the ring lamp plate 130, thereby mechanically connecting the ring lamp plate 130 to the inner surface of the upper shell 132. The support structure 154 may be configured in columnar, plate-like, ribbed, or other suitable forms to provide stable mechanical support while accommodating electrical routing and assembly requirements.

[0113] In an embodiment, the first stimulation element 170 may include a phototherapy lamp 126 located in the storage space, and the light-emitting units 128, for example, LEDs, of the phototherapy lamp 126 correspond to the light-transmitting hole 136 so that emitted light exits through the light-transmitting hole 136 and the light transmission plate 162. Concretely, the phototherapy lamp 126 may be implemented as a ring lamp plate 130 carrying a plurality of light-emitting units 128 disposed around the ring; each light-emitting unit 128 is aligned with a respective light-transmitting hole 136 so that light is delivered outwardly in controlled locations. Because the remainder of the upper shell 132 is light-blocking and the inner baffle 138 further prevents stray light transmission through the central opening, light may be emitted through the intended transmission holes, increasing efficacy and user comfort.

[0114] In an embodiment, the upper shell 132 is formed as a light-blocking structure except where light transmission is required. The roof plate 134 is provided with at least one light-transmitting hole 136, and the physiotherapy device 116 further includes a circular light transmission plate 162 that is superposed over the exterior of the roof plate 134 to cover the light-transmitting hole 136, and to distribute the light evenly on the surface of the full place for better stimulation, phototherapy.

[0115] In an embodiment, the first stimulation element 170 may include at least one microcurrent electrode 124 exposed at the upper end of the physiotherapy device 116. In a representative configuration, two microcurrent electrodes 124 are provided, one may be serving as a positive electrode, and the other may be serving as a negative electrode. The microcurrent electrodes 124 may be crescent-shaped, circular, annular, or otherwise configured according to ergonomic or functional considerations, without limitation. Each microcurrent electrode 124 is electrically connected to the ring lamp plate 130 via a conductive structure such as an electrode contact, conductive column, or equivalent conductive member, thereby enabling coordinated electrical control under the main circuit system, driven by the control board 166.

[0116] In an embodiment, the microcurrent electrodes 124 may deliver current in the range of approximately 10 µA to 600 µA, such as 50 µA, 100 µA, 200 µA, 300 µA, or 500 µA, without limiting to it. The voltage applied to the microcurrent electrodes 124 may be less than 60V DC. The microcurrent may be delivered as direct current (DC), pulsed current, or alternating waveforms with frequencies in the range of approximately 0.1 Hz to 1000 Hz. The electrode material may include gold, gold-plated copper, stainless steel (such as 316L), titanium, or platinum, without limiting to it.

[0117] In an embodiment, the light-transmitting holes 136 are arranged in a staggered relationship relative to the microcurrent electrodes 124. Both the light-transmitting hole 136 and the microcurrent electrodes 124 are positioned on the same side of the upper shell 132, thereby enabling simultaneous phototherapy and microcurrent stimulation while preventing functional interference between optical and electrical components.

[0118] In an embodiment, the light-emitting units 128 may emit red, infrared, blue, or violet light without limitation. The light-emitting units 128 may emit the same wavelength, or a subset of units may emit one wavelength while others emit a different wavelength, thereby supporting single-wavelength or mixed-wavelength phototherapy regimes. Optionally, the lower shell 148 may also be formed as a light-blocking structure so that emission is confined to the light-transmitting hole 136.

[0119] In an embodiment, the light-emitting units 128 may have an irradiance or power density in the range of approximately 5 mW / cm² to 100 mW / cm², such as 10 mW / cm², 20 mW / cm², 30 mW / cm², or 50 mW / cm², without limiting to it. Each light-emitting unit 128 may be driven at a current in the range of approximately 10 mA to 100 mA. The total optical output power of the phototherapy lamp 126 may be in the range of approximately 50 mW to 500 mW. Treatment duration may be controlled by the control board 166 and may range from approximately 1 minute to 20 minutes per session.

[0120] In an embodiment, the stimulation element can be the heating and cooling component configured to provide controlled thermal therapy. The heating and cooling component may include a Peltier module, a resistive heating plate, or a thermoelectric component disposed beneath or adjacent to the light-transmitting plate. The thermal component is thermally coupled to the surface of the housing so that heat or coolness is effectively transferred to the user's skin. The control circuit regulates the direction and magnitude of current through the Peltier component to alternately produce heating or cooling effects.

[0121] In an embodiment, the stimulation element can be the magneto-therapy component that may include one or more electromagnetic coils or permanent magnets configured to generate a pulsed or static magnetic field to promote blood circulation and cellular metabolism. The stimulation element can be the ultrasonic wave therapy component that may include one or more piezoelectric transducers adapted to emit ultrasonic vibrations in the range of 0.8-3 MHz to stimulate tissue regeneration, enhance transdermal absorption of skincare products, and relieve muscular tension.

[0122] In an embodiment, the phototherapy component provides optical stimulation using specific wavelengths of light, while the microcurrent component delivers controlled low-level electric currents through electrodes on the device surface. The heating and cooling components, including the thermoelectric (Peltier) component, regulate the surface temperature to deliver thermal therapy for soothing or tightening skin. All these components may be controlled individually or simultaneously through the circuit board and user interface, allowing the user to select desired therapy modes depending on treatment needs.

[0123] In an embodiment, the battery 164 and the control board 166 are arranged approximately opposite to one another along the radial direction of the physiotherapy device 116, for example, roughly 180° apart, so that mass and weight are balanced around the ring, improving handling and preventing a pronounced imbalance during use. The peripheral side of the physiotherapy device 116 and the corresponding portion of the control board 166 may be provided with a charging port 168 to enable recharging of the battery 164, via wired or wireless charging. The control board may be operated wirelessly, for example, by Bluetooth connection, or other apps.

[0124] In an embodiment, the battery 164 may have a capacity in the range of approximately 100 mAh to 1000 mAh, such as 200 mAh, 300 mAh, 500 mAh, or 800 mAh, without limiting to it. The battery 164 may have a nominal voltage of approximately 3.7V for lithium-ion or lithium-polymer cells, or approximately 3V for button cells. The control board 166 may include a charging circuit supporting constant-current constant-voltage (CC-CV) charging, battery protection circuitry for over-charge, over-discharge, and over-current protection, and a fuel gauge for battery state monitoring. Power consumption may be approximately 0.5W to 2W for heating mode, 0.1W to 0.5W for phototherapy mode, and 0.05W to 0.2W for microcurrent mode.

[0125] In an embodiment, the skin care therapy device further includes a sealing or occlusion cover 112 that is connected to the side of the skincare container 100, proximate the physiotherapy device 116. The occlusion cover could be transparent, translucent, or opaque, preferably opaque here. The occlusion cover 112 is provided with a plugging bulge 114 configured to be inserted into the liquid outlet 110. In the arrangement, the occlusion cover 112 cooperates with the bottle cap 104 to clamp the physiotherapy device 116 and thereby prevent the physiotherapy device 116 from falling off, and is easily detachable. Insertion of the plugging bulge 114 into the liquid outlet 110 reduces or restricts the risk of leakage from the liquid outlet 110. As the occlusion cover 112 is located in contact with the side of the physiotherapy device 116 that faces the upper end face of the physiotherapy device 116, pressure applied to the occlusion cover 112 is not translated into downward movement of the pressing head 108, thereby avoiding accidental dispensation when the occlusion cover 112 is touched or pressed accidentally.

[0126] In an embodiment, the plugging bulge 114 and the occlusion cover 112 may be formed as a single integrated structure, for example, by injection molding from a materially uniform hard plastic without restriction. Alternatively, the plugging bulge 114 may be formed from a softer elastomeric material, such as a sealing ring, while the occlusion cover 112 may be formed from a harder plastic, for instance, using a two-shot molding process. When formed from a soft sealing material, the plugging bulge 114 can provide an improved fluid seal at the liquid outlet 110 and further reduce leakage risk. These materials and manufacturing options provide design flexibility without constraining the scope of the invention.

[0127] In an embodiment, the occlusion cover 112 completely covers the upper end of the physiotherapy device 116 and the pressing head 108, so as to protect the first stimulation element 170 on the physiotherapy device 116 from contamination or wear and to prevent inadvertent activation or accidental depressing of the pressing head 108. This protective function preserves device hygiene and helps maintain reliable operation over time.

[0128] In an embodiment, the physiotherapy device 116 comprises a first portion 118 and a second portion 120 located at the upper end of the first portion 118. The first portion 118 and the second portion 120 of the physiotherapy device 116 are connected to form a step for the occlusion cover on the physiotherapy device. The cross-section of the second portion 120 is smaller than that of the first portion 118, and the periphery of the second portion 120 is provided with a snap bump 122. The interior of the occlusion cover 112 is provided with a snap slot configured to receive the snap bump 122, and the end of the occlusion cover 112 is attached to the upper end of the first portion 118. In this way, the first portion 118 and second portion 120 form a stepped profile, the first portion 118 being larger than the second portion 120, which provides a stable seating surface and an intuitive mechanical interface for clipping the occlusion cover 112.

[0129] In an embodiment, the occlusion cover 112 includes a disc-shaped central portion and an annular convex edge surrounding the disc. The disc-shaped portion overlies the second portion 120, while the convex edge is disposed around the periphery of the second portion 120 and defines an interior snap slot that engages the second portion 120. The convex edge also connects to the upper end of the first portion 118, such that the occlusion cover 112 covers and protects the second portion 120. By mechanically coupling the occlusion cover 112 to the physiotherapy device 116 in this manner, the occlusion cover 112 is not easily separated during normal use, and the closure of the liquid outlet 110 is reliably maintained.

[0130] In some embodiments, the first stimulation element 170 is arranged at the upper end of the second portion 120, and a gap is maintained between the occlusion cover 112 and the first stimulation element 170 in the vertical direction so that, when the occlusion cover 112 is installed, it does not collide with or press against the first stimulation element 170, and cause scratching or damage. This spacing prevents mechanical abrasion or deformation of the first stimulation element 170 and avoids damage to electrical contacts. For example, when the first stimulation element 170 comprises microcurrent electrodes 124, the microcurrent electrodes 124 are not compressed by the occlusion cover 112, thereby preserving electrode integrity and electrical connectivity.

[0131] The pump 106 further comprises a second stimulation element configured to apply physiological stimulation to a skin surface while the skincare product is dispensed through the dispensing end. The second stimulation element may include, but is not limited to, a heating element, a microcurrent element, a Peltier element, a vibrational element, a thermal element, or a combination thereof. The second stimulation element is located in or on the pressing head 108 or pump 106 to provide additional therapeutic or cosmetic stimulus during or after dispensing.

[0132] In an embodiment, the second stimulation element comprises a heating element 186 embedded in the pressing head 108 and thermally coupled to a concave arc surface 188. The pressing head 108 provides the concave arc surface 188 with a depth of 1 to 3 mm, with a liquid outlet 110 located centrally at the lowest point. Multi-hole or single-hole may be present for more dispersed dispensing. The heating element 186 may be an embedded type, for example, a resistance, ceramic, or graphene heater, without limiting to it, thermally coupled to the pressing head 108 but electrically insulated from the liquid and skin.

[0133] In an embodiment, the second stimulation element may comprise at least one microcurrent electrode disposed on the dispensing end of the pump 106. The microcurrent electrode on the dispensing end may be configured to deliver localized electrical stimulation to the skin during or immediately after dispensing of the skincare product. The microcurrent electrode on the pump 106 may work independently or in coordination with the microcurrent electrodes 124 on the physiotherapy device 116 (first stimulation element) to provide enhanced electrical stimulation coverage. The microcurrent electrode on the dispensing end may be electrically connected to the battery 164 and main control board 166 in the physiotherapy device 116 via the electrical connection system as first electrode 196 and second electrode 198. The microcurrent delivered through the dispensing end electrode may be in the range of approximately 10 µA to 600 µA, and may be delivered as direct current (DC), pulsed current, or alternating waveforms. This configuration enables the user to receive microcurrent stimulation while the skincare product is being dispensed, promoting immediate absorption and enhancing the therapeutic effect of the skincare product.

[0134] In an embodiment, the heating element 186 may have a power rating in the range of approximately 1W to 5W. Thermal coupling between the heating element 186 and the concave arc surface 188 may be achieved through direct contact, thermal paste, thermally conductive adhesive, or potting compound. The heating element 186 may be thermally insulated from the liquid pathway using an insulating layer or air gap to prevent thermal degradation of heat-sensitive skincare actives.

[0135] In an embodiment, the curvature of the concave arc surface 188 may be designed to adapt to the size of the skin care area. For curved areas such as around the eyes and nose, where a smaller amount of skin care product is needed, a shallow concave arc surface 188 with a radius of 5mm-10mm may be used, without limiting to it. For large-area application on the face, a gently sloping concave arc surface 188 with a smaller arc radius may be used to increase the capacity of the skin care product. The concave design helps to gather the skincare product, preventing waste caused by splashing or flowing after dispensing.

[0136] In an embodiment, an electrical connection is provided between the pump 106 and the physiotherapy device 116 so that electrical power and / or control signals are transmitted from the physiotherapy device 116 to the second stimulation element in the pump 106. A first electrode 196 is exposed on the inner peripheral surface of the physiotherapy device 116 and is electrically connected to the battery 164. A second electrode 198 is exposed on the outer peripheral surface of the pressing head 108 and is electrically connected to the second stimulation element, such as the heating element 186. When the physiotherapy device 116 is positioned such that the first electrode 196 and the second electrode 198 contact, a circuit is closed to power the second stimulation element.

[0137] In an embodiment, the electrical connection comprises sliding conductive contacts between the pump 106 and the physiotherapy device 116. Alternatively, the electrical connection may comprise pogo-pin electrodes. The first electrode 196 on the inner wall of physiotherapy device 116 and the second electrode 198 on the outer periphery of pressing head 108 are shaped to mate reliably, may be by an arc-shaped ring, small spring-loaded contacts, or pogo-pin style contacts. First electrode 196 and second electrode 198 surfaces are corrosion-resistant, may be metal plated, for example, gold-plated, or stainless.

[0138] In an embodiment, when the second stimulation element is a heating element 186, a temperature sensor thermistor may be used in proximity to the concave arc surface 188 for closed-loop control, with thermal cutoff, operated through the control board 166. The temperature sensor may be an NTC thermistor, PTC thermistor, thermocouple, or RTD (resistance temperature detector), without limiting to it. The control board 166 may implement closed-loop temperature control using on-off control, proportional control, or PID (proportional-integral-derivative) control algorithms. The safety cutoff temperature may be set in the range of approximately 43°C to 50°C, such as 45°C, to prevent skin burns or product degradation. The temperature control system may have a response time of less than 5 seconds to reach the target temperature.

[0139] In an embodiment, the electrical connection is established only when the physiotherapy device 116 is in an assembly position relative to the pump 106. The heating element 186 only energizes when the first electrode 196 and the second electrode 198 contact. When the physiotherapy device 116 is removed or moved out of the assembly position, the heating element 186 is unpowered. The physiotherapy device is powered with current-limiting, temperature cutoff, and an indicator LED for heating active and ready. The battery 164 may be a small Li-ion rechargeable or button-cell for a low-power heater; design heating power to match battery 164 capacity and thermal safety margins.

[0140] In an embodiment, the physiotherapy device 116 includes a control board configured to control both the first stimulation element 170 and the second stimulation element in the pump 106. The main control board 166 is electrically connected to the battery 164 and is arranged inside the physiotherapy device 116, for example, within the enclosed storage space formed by the upper shell 132 and lower shell 148. The main control board 166 provides regulated power and control signals to each stimulation element and sensor including, the second stimulation element such as heating element 186 embedded in the pressing head 108 and thermally coupled to the concave arc surface 188, the first stimulation element 170, the phototherapy lamp 126 and its light-emitting units 128 carried on the ring lamp plate 130, and any temperature sensor or thermistor associated with the pressing head 108. The main control board 166 implements safety and feedback routines such as current limiting, over-temperature cut-off, closed-loop temperature control based on the temperature sensor, timed operation of stimulation modes, and battery management, including charge level monitoring and low-voltage cut-out.

[0141] In an embodiment, building upon the basic structure described above, the physiotherapy device 116 is movable relative to the bottle cap 104 along an axial direction (first axis) to switch between a first position and a second position. When the physiotherapy device 116 is in the first position, the therapy surface of the physiotherapy device 116 is at least a height equal to, lower than, the height of the pressing end of the pump 106. When the physiotherapy device 116 is in the second position, the therapy surface of the physiotherapy device 116 is at a height greater than the height of the pressing end of the pump 106. This positional movement enables separation of dispensing and therapy functions while maintaining structural stability during use.

[0142] In an embodiment, a guide structure is provided on the bottle cap 104. The guide structure comprises a hollow cylindrical guide sleeve 174 disposed on the bottle cap 104 and surrounding the outer periphery of the installation channel 180. The guide sleeve 174 extends axially and is coaxial with the installation channel 180. The pump 106 may be a columnar pump that slides axially inside the guide sleeve 174 and the installation channel 180. The pump core contains a piston chamber, an inlet valve at the inlet end 192, an outlet valve at the pump outlet end 190, and a return spring for positioning back to the original position after use. The pressing head 108 forms the outermost axial face of the pump core and includes the pressing head 108 with the central liquid outlet 110.

[0143] In an embodiment, the outer peripheral surface of the guide sleeve 174 is provided with a first positioning groove 176 and a second positioning groove 178 that are spaced apart along the axial direction. The first positioning groove 176 corresponds to a first position, and the second positioning groove 178 corresponds to a second position. The physiotherapy device 116 is fitted around the outer periphery of the guide sleeve 174 and can slide along the axial direction.

[0144] In an embodiment, the inner peripheral wall of the physiotherapy device 116 is provided with a flexible circumferential positioning strip 194 that engages one or more annular positioning grooves on the guide sleeve 174. The positioning strip 194 can be embedded in the first positioning groove 176 or the second positioning groove 178 to lock the physiotherapy device 116 in the first position or the second position.

[0145] In an embodiment, when the physiotherapy device 116 is in the first position (dispense position), the pressing head 108 is exposed and accessible centrally, present slightly above the physiotherapy surface or first stimulation element 170 surface. The user may press axially on pressing head 108 from direct finger or a small applicator. The downward travel compresses the internal spring and moves the pump piston, closing the inlet valve and opening the outlet valve so skincare fluid flows from the pump chamber through the pump outlet end 190 and out the liquid outlet 110 onto the concave arc surface 188. The concave geometry collects the dispensed drop at the bottom for immediate fingertip application, or in the depth of the concave surface. When the user releases, the spring returns the pump 106 to its rest position, the inlet valve reopens, and the chamber refills from the bottle body 102 via the inlet end 192.

[0146] In an embodiment, when the physiotherapy device 116 is in the second position (therapy position), the height of the therapy surface in the axial direction is greater than the height of the pressing head 108. A predetermined separation "D" when the physiotherapy device is in the second position may present, between the physiotherapy device 116 surface and pressing head 108, between 1 and 5 mm, such as 1.2mm, 1.5mm, 1.7mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 4.8mm, without limiting to it. When the user uses the therapy surface to apply therapy to the skin, the skin is less likely to accidentally contact the lower pressing head 108 or be obstructed by the pump 106.

[0147] In an embodiment, the physiotherapy device 116 is connected to the base via a sliding fit structure, a snap-fit structure, or a threaded connection structure to switch between the first position and the second position. The sliding fit adapts to the assembly relationship between the physiotherapy device 116 and the guide sleeve 174, achieving smooth sliding based on the contact surfaces of the two.

[0148] In an embodiment, the physiotherapy device 116 threads onto the guide sleeve 174, for example, an internal thread on the physiotherapy device 116, matching the external thread on the guide sleeve 174. Rotating the physiotherapy device 116 may convert the rotary motion to precise axial displacement. Thread pitch determines displacement per revolution choose pitch so that one to three turns give the required displacement, for example, 0.5 to 2 mm per 90° rotation. Thread self-locking keeps the device fixed without extra latching.

[0149] In an embodiment, when the device includes a second stimulation element, the positional movement may control the electrical connection. In the first position, the first electrode 196 on the inner circumference of the physiotherapy device 116 contacts the second electrode 198 on the pump 106. This closes the circuit between battery 164 and the second stimulation element, such as heating element 186, powering the second stimulation element. Representative comfortable preset temperature for heating element 186 is provided from approximately 38 to 42 °C, without limiting to it, the preset temperature could be between any range suitable for the need up to 100 °C.

[0150] In an embodiment, after dispensing the liquid from the bottle body 102, on sliding the physiotherapy device 116 upward along the guide sleeve 174, the positioning strip disengages from the first positioning groove 176 and snaps into the second positioning groove 178, and the physiotherapy device 116 successfully comes to the second position. On moving to the second position, the first electrode 196 separates from the second electrode 198, and the second stimulation element, such as heating element 186, is immediately de-energized by the control board 166, avoiding unnecessary heating while the therapy is applied. The first stimulation element 170, which may host LEDs, microcurrent electrodes, RF coil, etc. are now above the pressing end and can be moved smoothly across the skin without obstruction, giving various therapies through the stimulation elements.

[0151] In an embodiment, guide sleeve 174 may contain three annular positioning grooves spaced axially, the lower first positioning groove 176 facilitating in dispensing liquid, a mid third groove may facilitate in heating-only position, and upper second positioning groove 178 facilitating in therapy. Positioning strip 194 on physiotherapy device 116 may lock into any of the three grooves, facilitating the regular detachment and locking for the respective function needed.

[0152] In an embodiment, when the physiotherapy device 116 is locked in the first positioning groove 176, the pressing head 108 is exposed, and the first electrode 196 and the second electrode 198 are not in contact. The pump 106 works as before, allowing dispensing without activating the second stimulation element if desired. This variant supports dispensing at room temperature when preferred. After dispensing, on sliding the physiotherapy device 116 upward into the third groove, the mid position electrodes, as first electrode 196 and second electrode 198, make contact, and the second stimulation element, such as heating element 186 is powered to preheat fluid collected in concave arc surface 188 until the predetermined temperature is reached. The heating period is controlled by an internal timer and temp sensor controlled through the control board 166 on the physiotherapy device 116. After preheating, on sliding the physiotherapy device 116 further to the second positioning groove 178, moving to the second position opens the electrode gap and de-energizes the second stimulation element immediately prior to skin contact, minimizing burn risk, and making the physiotherapy device ready for applying to the skin. Separating the second stimulation element activation into its own locked position enables precise activation durations and prevents the second stimulation element from running during dispensing or therapy unless explicitly placed in the assembly position.

[0153] In an embodiment, removing the physiotherapy device 116 fully breaks contact between the first electrode 196 and the second electrode 198 and de-energizes the second stimulation element. The annular physiotherapy device 116 may be detached for independent use, as it is ergonomic, of lighter weight, powered by an inbuilt battery 164, and functions controlled by the control board 166. As the physiotherapy device 116 is detachable, making it easy to clean or replace, and operate. Seals and the guide sleeve keep the pump core sealed when the device is detached. A flexible sealing object may be present attached between pump 106 and the physiotherapy device 116, preventing the defecting of the first electrode 196 and the second electrode 198, which may be made of a pogo pin, from the discharged liquid, also from environmental moisture.

[0154] In another embodiment, the pressing element 204 may be formed as a single protruding lug projecting outward from the outer peripheral wall of the pressing head. This pressing element 204is arranged perpendicular to the first axis, giving direct, loss-minimized transmission of manual force to pump core. The lug may be rectangular or gently arc-shaped in plan, sized to accommodate a single fingertip, without limiting to it and may incorporate a thin silicone anti-slip pad bonded to the pressing element 204 for tactile feedback and to prevent slippage during operation. In another embodiment, symmetric twin lugs as two opposing pressing element 204 features spaced approximately 180° apart, may be provided so that the user may squeeze between two fingers for a longer moment arm and improved force control. The pressing element 204 may be elastic or spring-loaded, for example, a soft silicone bump over a small spring-plunger that permits a short, controlled travel and tactile pre-travel before the pump core is driven, this spring-assisted design may reduce accidental actuation and improve the perceived quality of operation for users requiring lower actuation force.

[0155] In an embodiment, the pressing notch 202 in the physiotherapy device 116 is designed to provide ergonomic access to pressing element 204 and to control the hand posture during operation. In the fan-shaped through-notch, pressing notch 202 extends radially through the device sidewall along the first axis, subtending a central angle selected from approximately 30° to 120° depending on user preference and device diameter, the minimum circumferential width is designed in the range of about 8 mm to 25 mm so that a single finger or a pair of fingers can comfortably engage pressing element 204 without contacting heating end face. A dual-opposing notch arrangement may be provided, as two smaller notches placed on opposite sides of the device, allowing alternate grip positions, for right- and left-handed users, while distributing structural weakening symmetrically. For multi-finger actuation, a low-height tall-width notch variant is provided where notch 202 has increased axial height and larger circumferential width to permit a thumb-and-index pinch or a two-finger press over a broader surface area.

[0156] In an embodiment, the first axis defines the principal direction of manual actuation and the aligned motion of pressing element 204 and pump core. The first axis coincides with the device central axis so that pressing force is applied axially and directly to pump core, producing a linear downward stroke optimised for simple push-release operation and minimal lateral loading. For ergonomic optimization an angled-axis embodiment tilts the first axis by a small angle, for example 5° to 20°, relative to the physiotherapy device central axis so that the pressing element 204 more naturally follows the user’s thumb or finger orientation during use, the pressing element 204 is maintained normal to the first axis so that force transmission remains axial with respect to the pump, and guide structures are aligned to the tilted first axis to avoid binding.

[0157] In another embodiment, the press pump 106 is mounted concentrically within a central mounting hole of bottle cap 104 so that the pressing element 204 is exposed through pressing notch 202 in the surrounding physiotherapy device 116, this layout keeps the pumping mechanism compact, aligns the axis of actuation with the device centre for balanced handling, and positions the pressing element 204 such that it can be accessed easily through notch 202. An offset-notch arrangement shifts pressing notch 202 circumferentially, to favor right- or left-handed operation in user-specific variants, this may be offered as left and right-handed models without altering internal pump geometry. The full guide structure 206 additionally incorporates venting grooves, on the guide rod or sleeve to avoid airlock and to allow pressure equalization during pump return. Where reduced component count and low stroke are acceptable, the guide sleeve 174 alone is used as a light-weight guide, relying on tight sliding tolerances between pressing head 108 and guide sleeve 174.

[0158] In an embodiment, the user may grip the device so that a thumb or finger enters pressing notch 202 and contacts the pressing element 204. When the user applies force along the first axis, the pressing element 204, causing pump core to translate and create positive pressure that draws liquid in through the inlet end 192 and forces fluid out through pump outlet end 190 and the liquid outlet 110. The dispensed liquid can be applied directly to the skin or collected briefly on the heating end face if warming is required. Releasing the force allows the pump’s internal return spring or elastic element to restore the pump core to its original position, drawing the chamber back into suction-ready state, this simple push-release cycle is reliable, requires minimal parts, and is suitable for low-stroke, low-cost devices where the guide structure 206 can be omitted or simplified.

[0159] In an embodiment, the device may include a guide structure comprising a guide hole at the bottom of the pressing member with an axis parallel to the first axis, and a guide rod with one end fixed to the bottle cap 104 and the other end slidably inserted through the guide hole. The guide hole and / or guide rod may be provided with venting grooves for venting air during movement of the pressing member. The venting grooves may be strip-shaped grooves extending along the axial direction, with a width and depth of approximately 0.5mm-1mm, without limiting to it, to ensure smooth airflow without affecting guiding accuracy.

[0160] In an embodiment, the guide structure may include a limiting groove formed on the guide sleeve 174 extending along the axial direction, and a limiting pin protruding from the outer peripheral wall of the pressing head 108 that is embedded in and slides along the limiting groove. The limiting pin may be elastic, such as a spring plunger pin, an elastic steel ball pin, or a silicone protrusion pin, without limiting to it, facilitating compression and insertion into the limiting groove. The limiting groove provides a sliding trajectory and limiting boundary for the limiting pin, precisely limiting the movement stroke of the pressing head 108 and preventing disengagement from the guide sleeve 174.

[0161] In an embodiment, the pump 106 may be facilitating in discharging liquid, gas, or mixtures without restriction from the skincare container 100 by application of compressive force. The pump 106 may include the pressing head 108, a piston, a spring, a suction tube, and at least one check valve. When the pressing head 108 is not depressed or pressed, the liquid in the skincare container 100 remains stationary, and the pump cavity is in pressure equilibrium with the liquid present in the container. On pressing the pressing head 108 compresses the piston and spring, thereby reducing the pump cavity volume and increasing cavity pressure. This pressure drives liquid out of the liquid outlet 110 while the internal check valve prevents backflow. On release, the spring returns the piston toward its original position, increasing the pump cavity volume and lowering the internal pressure so that liquid is drawn into the pump cavity through the suction tube, with the suction-end check valve ensuring one-way flow.

[0162] In an embodiment, the physiotherapy device 116 is ring-shaped and is arranged concentrically around the pressing head 108 so that the liquid outlet 110 remains exposed outside the physiotherapy device 116. The physiotherapy device 116 is fixed relative to the bottle body 102 so that, when the pressing head 108 is depressed, the physiotherapy device 116 is retained in its position relative to the bottle body 102, and the user may dispense product without removing the physiotherapy device 116. As the liquid outlet 110 is unobstructed by the physiotherapy device 116, users can access the dispensed product conveniently. Positioning the physiotherapy device 116 around the pressing head 108 also provides practical storage for the device and reduces the chance of misplacement while keeping the kit compact.

[0163] In an embodiment, the physiotherapy device 116 is also configured to be removable from the bottle body 102 and the bottle cap 104 so that it can be used independently from the skincare container 100. The ability to separate the physiotherapy device 116 from the skincare container 100 preserves the versatility of use and cleaning, replaceability, and enables independent charging or maintenance of the device.

[0164] In an embodiment, the physiotherapy device 116 is attached to the bottle cap 104. The physiotherapy device 116 simply overlies the top face of the bottle cap 104, in alternative embodiment magnet fasteners are provided between the physiotherapy device 116 and the bottle cap 104 to realize magnetic retention, a snap feature for example, a convex snap on one component and a corresponding slot on the other is used to mechanically clip the physiotherapy device 116 to the bottle cap 104. These selectable retention mechanisms provide reliable positioning while permitting intentional detachment when required.

[0165] In an embodiment, the skin care therapy device further includes a sealing or occlusion cover 112 that is connected to the side of the skincare container 100, proximate the physiotherapy device 116. The occlusion cover could be transparent, translucent, or opaque, preferably opaque here. The occlusion cover 112 is provided with a plugging bulge 114 configured to be inserted into the liquid outlet 110. In the arrangement, the occlusion cover 112 cooperates with the bottle cap 104 to clamp the physiotherapy device 116 and thereby prevent the physiotherapy device 116 from falling off, and is easily detachable. Insertion of the plugging bulge 114 into the liquid outlet 110 reduces or restricts the risk of leakage from the liquid outlet 110. As the occlusion cover 112 is located in contact with the side of the physiotherapy device 116 that faces the upper end face of the physiotherapy device 116, pressure applied to the occlusion cover 112 is not translated into downward movement of the pressing head 108, thereby avoiding accidental dispensation when the occlusion cover 112 is touched or pressed accidentally.

[0166] In an embodiment, the plugging bulge 114 and the occlusion cover 112 may be formed as a single integrated structure, for example, by injection molding from a materially uniform hard plastic without restriction. Alternatively, the plugging bulge 114 may be formed from a softer elastomeric material, such as a sealing ring, while the occlusion cover 112 may be formed from a harder plastic, for instance, using a two-shot molding process. When formed from a soft sealing material, the plugging bulge 114 can provide an improved fluid seal at the liquid outlet 110 and further reduce leakage risk. These materials and manufacturing options provide design flexibility without constraining the scope of the invention.

[0167] In an embodiment, the occlusion cover 112 completely covers the upper end of the physiotherapy device 116 and the pressing head 108, so as to protect the first stimulation element 170 on the physiotherapy device 116 from contamination or wear and to prevent inadvertent activation or accidental depressing of the pressing head 108. This protective function preserves device hygiene and helps maintain reliable operation over time.

[0168] In an embodiment, the occlusion cover 112 onto the bottle body 102 opening may be a threaded, snap, or gasketed fit. The installation channel 180 opens into the bottle body 102 interior. The pump 106 may be present in the installation channel 180 through the guide sleeve 174, and the inlet end 192 reaches the pressing head 108 exposed above the guide sleeve 174. The return spring may be present to keep the pump 106 upward or in the rest position. The circular physiotherapy device 116 is fitted over the guide sleeve 174 so it can slide axially. Initially, the positioning strip 194 is located over the first positioning groove 176, in the first position.

[0169] In an embodiment, in an embodiment, the physiotherapy device 116 comprises a first portion 118 and a second portion 120 located at the upper end of the first portion 118. The first portion 118 and the second portion 120 of the physiotherapy device 116 are connected to form a step for the occlusion cover on the physiotherapy device. The cross-section of the second portion120 is smaller than that of the first portion 118, and the periphery of the second portion120 is provided with a snap bump 122. The interior of the occlusion cover 112 is provided with a snap slot configured to receive the snap bump 122, and the end of the occlusion cover 112 is attached to the upper end of the first portion 118. In this way, the first portion 118 and second portion 120 form a stepped profile, the first portion 118 being larger than the second portion 120, which provides a stable seating surface and an intuitive mechanical interface for clipping the occlusion cover 112.

[0170] In an embodiment, the occlusion cover 112 includes a disc-shaped central portion and an annular convex edge surrounding the disc. The disc-shaped portion overlies the second portion 120, while the convex edge is disposed around the periphery of the second portion 120 and defines an interior snap slot that engages the second portion 120. The convex edge also connects to the upper end of the first portion 118, such that the occlusion cover 112 covers and protects the second portion 120. By mechanically coupling the occlusion cover 112 to the physiotherapy device 116 in this manner, the occlusion cover 112 is not easily separated during normal use, and the closure of the liquid outlet 110 is reliably maintained.

[0171] In some embodiments, the physiotherapy device 116 has stimulation elements, for example, a first stimulation element 170, a phototherapy lamp 126 providing phototherapy. The first stimulation element 170 is arranged at the upper end of the second portion 120, and a gap is maintained between the occlusion cover 112 and the first stimulation element 170 in the vertical direction so that, when the occlusion cover 112 is installed, it does not collide with or press against the first stimulation element 170, and cause scratching or damage. This spacing prevents mechanical abrasion or deformation of the first stimulation element 170 and avoids damage to electrical contacts. For example, when the first stimulation element 170 comprises microcurrent electrodes 124, the microcurrent electrodes 124 are not compressed by the occlusion cover 112, thereby preserving electrode integrity and electrical connectivity.

[0172] In an embodiment, the upper shell 132 is formed as a light-blocking structure except where light transmission is required. The roof plate 134 is provided with at least one light-transmitting hole 136, and the physiotherapy device 116 further includes a circular light transmission plate 162 that is superposed over the exterior of the roof plate 134 to cover the light-transmitting hole 136, and to distribute the light evenly on the surface of the full place for better stimulation, phototherapy.

[0173] In an embodiment, by employing the concave-convex interlocking configuration, accurate circumferential positioning is achieved during assembly, while simultaneously restricting undesired relative displacement between the mating plate 142 and the outer baffle 156. Furthermore, when the mating plate 142 and the outer baffle 156 are manufactured in distinct colors or surface finishes, the interlocked regions may produce differentiated visual effects, thereby enhancing aesthetic versatility and enabling design customization without altering functional performance.

[0174] In an embodiment, the lower end of each stiffener 172 protrudes downward beyond the lower end of the corresponding convex part 146. The base plate 150 is provided on its upper surface with a plurality of positioning slots 152. The lower end of each stiffener 172 is insertable into the positioning slots 152, thereby achieving precise axial positioning during assembly and effectively preventing unintended rotational or lateral movement of the mating plate 142. This arrangement enhances assembly reliability and mechanical robustness.

[0175] In alternative embodiments, stiffening ribs may additionally or alternatively be formed on the inner side of the convex portions of the outer baffle 156, thereby further strengthening the overall annular structure while maintaining the same functional principle.

[0176] In an embodiment, the lower shell 148 further includes a connecting plate 158 disposed on the inner side of the base plate 150. The connecting plate 158 is annular in configuration. The limiting groove 160 is formed along the inner circumference of the connecting plate 158, while a corresponding limiting protrusion 140 is formed along the outer circumference of the inner baffle 138. The connecting plate 158 is arranged around the outer periphery of the inner baffle 138 such that the limiting groove 160 engages with the limiting protrusion 140 in a snap-fit manner. This cooperative engagement prevents separation of the connecting plate 158 relative to the inner baffle 138 and ensures stable structural integration of the upper shell 132 and lower shell 148.

[0177] In an embodiment, the limiting groove 160 and the limiting protrusion 140 may extend circumferentially along the lower shell 148 and may be provided in multiple segments distributed around the circumference, thereby enhancing circumferential locking strength and load distribution.

[0178] In an embodiment, the physiotherapy device 116 is in the first position when the pressing head 108 is exposed and accessible centrally, present slightly above the therapy surface or first stimulation element 170 surface, when in the first position. The user may press axially on pressing head 108 from direct finger or a small applicator. The downward travel actuates the pump 106 to dispense skincare fluid through the liquid outlet 110 onto the concave arc surface 188. The concave geometry collects the dispensed drop at the bottom for immediate fingertip application, or in the depth of the concave surface. When the user releases, the spring returns the pump 106 to its rest position, the inlet valve reopens, and the chamber refills from the bottle body 102 via the inlet end 192.

[0179] In an embodiment, the sensor for detecting the user's skin type may include an impedance sensor, a capacitance sensor, an optical reflectance sensor, or a combination thereof. The impedance sensor may measure skin hydration levels by applying a small AC signal and measuring the resulting impedance. The optical sensor may measure skin tone, oiliness, or other optical properties by emitting light and detecting reflected light intensity. The control board 166 may process sensor data and select the appropriate compartment for dispensing based on predetermined skin type profiles or user-configured preferences.

[0180] In an embodiment, the skincare therapy device comprises at least one sensor configured to detect a skin parameter of a user. The at least one sensor is disposed on the therapy surface of the physiotherapy device 116, on the pressing head 108, or on a dedicated sensing region of the device configured to contact the user's skin prior to dispensing.

[0181] In an embodiment, the at least one sensor comprises an impedance sensor configured to measure skin hydration level. The impedance sensor comprises at least two electrodes, which may be the microcurrent electrodes 124 or dedicated sensing electrodes, spaced apart on the therapy surface. The control board 166 applies a low-amplitude alternating current signal, such as in the range of 1 kHz to 100 kHz, between the electrodes and measures the resulting impedance. Lower impedance values indicate higher skin hydration, while higher impedance values indicate lower skin hydration. The control board 166 compares the measured impedance value against predetermined threshold values stored in memory to classify the skin hydration level as low, normal, or high.

[0182] In an embodiment, the at least one sensor comprises a capacitance sensor configured to measure skin moisture content. The capacitance sensor comprises interdigitated electrodes disposed beneath a thin dielectric layer on the therapy surface. The control board 166 measures the capacitance between the interdigitated electrodes, which varies based on the dielectric properties of the skin in contact with the sensor surface. The measured capacitance value is correlated to skin moisture content using a calibration curve stored in the control board 166 memory.

[0183] In an embodiment, the at least one sensor comprises an optical reflectance sensor configured to measure skin oiliness, skin tone, or other optical properties. The optical reflectance sensor comprises at least one light-emitting element, such as an LED emitting light in the visible or near-infrared spectrum, and at least one photodetector configured to detect light reflected from the user's skin. The ratio of reflected light intensity to emitted light intensity is indicative of skin surface properties. Higher reflectance at certain wavelengths may indicate oilier skin, while lower reflectance may indicate drier skin. The control board 166 processes the reflectance data to determine skin oiliness level.

[0184] In an embodiment, the at least one sensor comprises a combination of an impedance sensor and an optical reflectance sensor to provide multi-parameter skin analysis. The control board 166 receives detection data from both sensors and applies a decision algorithm to determine an overall skin condition classification.

[0185] In an embodiment, the control board 166 is configured to determine a skin condition based on the detection data by comparing the measured sensor values against predetermined threshold values or ranges stored in a lookup table in non-volatile memory. The lookup table associates ranges of sensor values with corresponding skin condition classifications, such as dry skin, normal skin, oily skin, combination skin, or sensitive skin.

[0186] In an embodiment, the control board 166 implements a decision tree algorithm to determine the skin condition. The decision tree comprises a series of conditional branches based on the measured sensor values. For example, if the measured impedance value exceeds a first threshold indicating low hydration, the algorithm branches to a dry skin classification. If the measured impedance value is below the first threshold and the measured optical reflectance value exceeds a second threshold indicating high oiliness, the algorithm branches to an oily skin classification. If neither condition is met, the algorithm branches to a normal skin classification.

[0187] In an embodiment, the control board 166 is configured to automatically control the pump 106 to dispense a selected skincare formulation based on the determined skin condition. The control board 166 stores in memory a mapping table that associates each skin condition classification with a corresponding compartment of the bottle body 102. Upon determining the skin condition, the control board 166 retrieves the corresponding compartment identifier from the mapping table and actuates the valve assembly to establish fluid communication between the pump chamber and the selected compartment.

[0188] In an embodiment, the control board 166 is further configured to select a therapy mode based on the determined skin condition and to activate the first stimulation element 170 and the second stimulation element based on the selected therapy mode. The control board 166 stores in memory a therapy mode table that associates each skin condition classification with corresponding stimulation parameters. For example, for dry skin, the therapy mode table may specify activation of the heating element 186 at a temperature of 40° C and activation of red light phototherapy at 630 nm to promote circulation and absorption. For oily skin, the therapy mode table may specify activation of blue light phototherapy at 415 nm to provide antibacterial treatment and no heating. The control board 166 retrieves the stimulation parameters from the therapy mode table and controls the stimulation elements accordingly.

[0189] In an embodiment, the control board 166 is configured to automatically dispense a blend of skincare formulations from two or more compartments based on the determined skin condition. For combination skin exhibiting both dry and oily regions, the control board 166 may control the valve assembly to dispense a mixture of a hydrating formulation and an oil-control formulation in a predetermined ratio, such as 1:1 or 2:1.

[0190] In an embodiment, the skincare therapy device comprises a user interface, such as a button, touch sensor, or wireless connection to a companion mobile application, configured to receive user input to initiate the skin analysis and automatic dispensing sequence. Upon receiving the user input, the control board 166 activates the at least one sensor, acquires detection data, determines the skin condition, selects the appropriate compartment, and actuates the pump 106 to dispense the selected formulation. A visual or audible indicator, such as an LED or beep, may be provided to indicate completion of the dispensing sequence.

[0191] In an embodiment, the control board 166 is configured to store historical skin condition data in non-volatile memory and to track changes in the user's skin condition over time. The companion mobile application may retrieve the historical data via wireless communication and display trends and recommendations to the user.

[0192] In an embodiment, the user may configure personalized skin condition thresholds and formulation preferences via the companion mobile application. The personalized settings are transmitted to the control board 166 and stored in non-volatile memory, enabling customized automatic dispensing tailored to the individual user's skin characteristics and preferences.

[0193] In an embodiment, the pressing head 108 comprises a circular pressing surface with an anti-slip texture. pressing head 108 provides the concave arc surface 188 with a depth of 1 to 3 mm, liquid outlet 110 located centrally at the lowest point. Multi-hole or single-hole may be present for more dispersed dispensing. The heating element 186 may be an embedded type, for example, a resistance, ceramic, or graphene heater, without limiting to it, thermally coupled to the pressing head 108 but electrically insulated from the liquid and skin. A temperature sensor thermistor may be used in proximity to the concave arc surface 188 for closed-loop control, with thermal cutoff, operated through the control board 166. The first electrode 196 on the inner wall of physiotherapy device 116 and the second electrode 198 on the outer periphery of pressing head 108 are shaped to mate reliably, may be by an arc-shaped ring, small spring-loaded contacts without limiting to it. First electrode 196 and second electrode 198 surfaces are corrosion-resistant, may be metal plated, for example, gold-plated, or stainless. The guide sleeve 174 may include openings where the electrode contacts can protrude during assembly positions.

[0194] In an embodiment, the temperature sensor may be an NTC thermistor, PTC thermistor, thermocouple, or RTD (resistance temperature detector), without limiting to it. The control board 166 may implement closed-loop temperature control using on-off control, proportional control, or PID (proportional-integral-derivative) control algorithms. The safety cutoff temperature may be set in the range of approximately 43° C to 50° C, such as 45° C, to prevent skin burns or product degradation. The temperature control system may have a response time of less than 5 seconds to reach the target temperature.

[0195] In an embodiment, the control board 166 may include skin contact detection circuitry configured to detect when the therapy surface is in contact with skin before activating microcurrent stimulation, preventing electrical shock when not in contact with skin. The control board 166 may implement an auto-shutoff timer that automatically deactivates stimulation after a predetermined treatment duration, such as 10 minutes, 15 minutes, or 20 minutes. The physiotherapy device 116 may include a motion sensor configured to pause therapy if the device is stationary for an extended period or if the device is dropped. A child lock feature may be provided to prevent accidental activation by children.

[0196] In an embodiment, the therapy surface and pressing head 108 may include an antimicrobial coating for hygiene, such as silver ion coating, copper-infused material, or other antimicrobial agents, without limiting to it. The bottle body 102 may be formed from UV-resistant materials to protect light-sensitive skincare formulations from degradation. The seals and gaskets contacting the skincare product may be formed from food-grade or medical-grade silicone to ensure biocompatibility and chemical resistance.

[0197] In an embodiment, when the physiotherapy device 116 is locked in the first position during dispensing, the first electrode 196 on the inner circumference of the physiotherapy device 116 contacts the second electrode 198 on the pump 106. This closes the circuit between battery 164 and the second stimulation element, such as heating element 186, powering the second stimulation element. Representative comfortable preset temperature for heating element 186 is provided from approximately 38 to 42 °C. The heating element 186 is embedded and does not directly contact the product or skin. During dispensing, the dispensed liquid passes immediately over the heated concave arc surface 188 and is pre-warmed before user application.

[0198] In an embodiment, after dispensing the liquid from the bottle body 102, on sliding the physiotherapy device 116 upward along the guide sleeve 174, the positioning strip 194 disengages from the first positioning groove 176 and snaps into the second positioning groove 178, and the physiotherapy device 116 successfully comes to the second position. On moving to the second position, the first electrode 196 separates from the second electrode 198, and the second stimulation element, such as heating element 186, is immediately de-energized by the control board 166, avoiding unnecessary heating while the therapy is applied. The first stimulation element 170, which may include LEDs, microcurrent electrodes, RF coil, etc. are now above the pressing end and can be moved smoothly across the skin without obstruction, giving various therapies through the stimulation elements.

[0199] In an embodiment, the sealing rings, O-rings, and gaskets may be formed from materials such as silicone rubber, EPDM (ethylene propylene diene monomer), fluoroelastomer (such as Viton), nitrile rubber, or thermoplastic elastomer, without limiting to it. The seal material may be selected for chemical compatibility with common skincare formulation ingredients, including water, glycerin, oils, alcohols, and surfactants. The seal hardness may be in the range of approximately 40 to 70 Shore A durometer.

[0200] In an embodiment, a flexible sealing object is provided between the pump 106 and the physiotherapy device 116 to protect the electrical contacts, for example, the first electrode 196 and second electrode 198, which may be pogo-pin style spring contacts, and to prevent ingress of discharged liquid or environmental moisture. The flexible sealing object may take the form of one or more of: an annular O-ring seated in a circumferential groove around the pump outlet, a thin elastomeric membrane or diaphragm spanning the central opening with a self-sealing axial slit or cross-slit to permit axial movement of the pump pressing head 108 while closing around the contact region, a U-profile axial lip seal that compresses against the pump outer surface when the physiotherapy device 116 is assembled, an accordion-bellows style flexible sleeve that accommodates axial travel, or an overmolded elastomeric gasket integrated into the physiotherapy device 116 inner periphery. The sealing object may be formed from at least one of silicone rubber, EPDM, nitrile rubber (NBR), fluoroelastomer (Viton), or a thermoplastic elastomer (TPE), selected for chemical compatibility with common skincare formulations and for long-term elasticity, without limiting to it. Where low friction and wear resistance are desired for repeated sliding engagement, the sealing object may be formed from a fluorosilicone or a PTFE-filled elastomeric compound. The sealing object may be sized and pre-compressed such that the pogo-pin contacts remain free to engage electrically, as the seal compresses around the pin bodies but does not restrict the required spring travel of the pogo pins, and may include a thin local relief-notch to receive the pogo head and accommodate lateral alignment. Typical geometric guidance may include O-ring cross sections of about 1.0 to 3.0 mm and membrane thicknesses in the range of 0.2 to 1.5 mm, and seal hardness may be about 40 to 70 Shore A without restriction, depending on the material and required sealing force. The sealing object may be attached by snap-fit into a mating groove, by adhesive bonding, by two-shot overmolding during manufacture, or by a thin retaining plate, enabling straightforward assembly and replacement. In one variant, the sealing object additionally incorporates a hydrophobic surface treatment or fluoropolymer coating to promote drainage of dispensed liquid away from the electrode gap and to reduce residue buildup. Provision of the flexible sealing object thus prevents defecting or corrosion of the electrode contacts from discharged liquid and ambient moisture, improves the device's washability and hygiene, and supports an improved ingress protection level for the assembled cap-and-physiotherapy module.
