Description

Technical Field

[0001] The invention belongs to the technical field of anti-itch devices, and particularly relates to an anti-itch structure and a portable mosquito repellent. Background Art

[0002] Mosquito bites are a very common nuisance in daily life. The symptoms such as itching, redness and swelling of the skin they cause are not only uncomfortable and affect work and rest, but in some cases may also lead to skin infections due to scratching or spread diseases through mosquitoes.

[0003] However, existing products and devices for relieving itching from mosquito bites utilize local application of heat energy, a widely recognized and applied physical method for alleviating itching. For example, heat is generated by an electric heating element, and then a heated surface is brought into contact with the itchy skin area to relieve discomfort.

[0004] However, heat transfer from the hot compress surface to the skin occurs primarily through conduction. The skin itself has a certain thermal resistance and heat capacity, and combined with the heat dissipation provided by subcutaneous blood flow, the effective depth of heat energy applied this way is typically limited, primarily confined to the epidermis and superficial dermis. In other words, this method of heating to relieve itching often has a superficial effect.

[0005] However, many mechanisms of itching are not limited to the outermost layer of the skin. For example, the pathological process of inflammatory reactions caused by mosquito bites, sensitization of nerve endings, or infiltration of immune cells involved in certain dermatitis may occur in deeper layers of the skin. Simple surface heating may not be able to effectively reach these deep tissues and cannot fundamentally regulate or block the itching signals or inflammatory processes dominated by deep factors. If the root cause of itching lies in persistent irritation or inflammation deeper under the skin, then the itch relief obtained by simply changing the temperature and sensation of the surface skin may be short-lived. Once the heat stimulus is eliminated, the itching sensation driven by deep factors may quickly recur. Summary of the Invention

[0021] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-7 as shown, the specific embodiments provided by the present invention are as follows: As Figures 1 to 3 shown, this embodiment provides an anti-itching structure 2, which is applied to a portable mosquito repellent, aiming to provide a convenient solution for users to relieve itching after being bitten by mosquitoes.

[0023] Referring to a specific implementation manner, the portable mosquito repellent has a main body 1. The anti-itching structure 2 described in this embodiment is disposed on the main body 1 of the portable mosquito repellent.

[0024] Specifically, the anti-itching structure 2 includes an infrared light emitting component 201. In this embodiment, the infrared light emitting component 201 specifically includes a plurality of infrared LED lamp beads. The infrared LED lamp beads are preferably disposed in a specific surface area of the main body 1 of the portable mosquito repellent, and this specific surface area is convenient for users to align it with the bitten area of the skin when needed. For example, the infrared LED lamp beads can be arranged in an array in a flat or slightly convex area of the mosquito repellent housing.

[0025] The infrared LED lamp beads are capable of emitting infrared light with a wavelength range of 630 nm to 650 nm. In order to achieve the anti-itching function, a corresponding control switch is also provided on the portable mosquito repellent for starting or closing the infrared light emitting component 201. The control switch can be an independent button or can be combined with other function switches of the mosquito repellent.

[0026] When the user's skin is bitten by a mosquito, hold the portable mosquito repellent and start the infrared light emitting component 201, for example, by pressing the control button, so that the plurality of infrared LED lamp beads emit infrared light with a wavelength range of 630 nm to 650 nm. Bring the part of the portable mosquito repellent provided with the infrared LED lamp beads close to or gently touch the skin area bitten by the mosquito.

[0027] Use the infrared light emitted by the infrared LED lamp beads to directly irradiate the skin surface of the bitten area for a period of time. Through the irradiation of this infrared light, it is expected to relieve or eliminate the itching sensation caused by mosquito bites.

[0028] In this embodiment, the infrared light emitting component 201 achieves the itching relief effect by emitting infrared light of a specific wavelength. The infrared LED lamp beads, as the light source, have the advantages of low power consumption, fast response speed, small size, etc., and are suitable for integration into portable electronic devices. The integration of this itching relief structure 2 with the portable mosquito repellent enables users to conveniently and quickly handle the itching problem after being bitten by mosquitoes when carrying out outdoor activities or using mosquito repellent products in daily life, thus enhancing the user experience.

[0029] In a specific manner, the plurality of infrared LED lamp beads are arranged inside the main body 1 of the portable mosquito repellent. Preferably, these infrared LED lamp beads are centrally arranged inside one end of the main body 1 of the portable mosquito repellent. In order to enable the infrared light emitted by the internal infrared LED lamp beads to effectively irradiate the external target area (such as the user's skin), on the end where the infrared LED lamp beads are arranged, at least in the area corresponding to the position of the infrared LED lamp beads, a light-transmitting structure 202 is provided. The light-transmitting structure 202 can be implemented in various ways: for example, a transparent housing (or transparent cover) can be provided at this end, and the transparent housing covers the outside of the infrared LED lamp beads, allowing the infrared light to transmit out unobstructed.

[0030] Or, it can also be that holes corresponding one by one to the positions of the infrared LED lamp beads or covering the entire lamp bead array, or through slots, are directly opened on the housing of this end, and the infrared light passes through these holes or slots and is emitted outward.

[0031] In a specific embodiment, the plurality of infrared LED lamp beads are compactly arranged in a circular array inside one end of the main body 1 of the portable mosquito repellent and are aligned with a preset light-transmitting structure 202 (such as a transparent housing, holes or slots) at this end.

[0032] This layout of the circular array can include, for example, 3 to 8 (or a specific number determined according to actual needs) infrared LED lamp beads, which are equidistantly or distributed at a specific angle on a preset circumference, or one or more lamp beads can be additionally arranged at the center position.

[0033] The circular array can project the infrared light energy of 630 nm to 650 nm emitted by the infrared LED lamp beads relatively more concentratedly onto a roughly circular treatment area. This generally matches the shape of the circular or oval redness and itching areas formed on the skin after being bitten by mosquitoes more closely, thereby ensuring effective coverage of the target area and a more uniform light distribution, which helps to enhance the effect of relieving itching.

[0034] On the other hand, the circular array layout itself has a relatively regular and compact structure, which is convenient for integration and fixation in the limited internal space of the portable mosquito repellent (especially at the end), and is also beneficial to the relevant circuit board design and wiring.

[0035] In addition, when the light is emitted from the circular array, the user can more intuitively align the center of the circular light spot with the bite, making the operation more convenient.

[0036] Therefore, setting the infrared LED lamp beads in a circular array and guiding the light out through the light-transmitting structure 202 at the end of the mosquito repellent is an optimal technical solution for achieving the anti-itching function described in the present invention, which takes into account the therapeutic effect, structural rationality and ease of use.

[0037] In a specific embodiment, in order to perform standardized control on the infrared light irradiation process and improve the user experience, the working time of the infrared LED lamp beads emitting infrared light has specific stages and cycles.

[0038] When the user activates the anti-itch function through the control switch on the portable mosquito repellent, the infrared LED lamp beads in the infrared light emitting component 201 are activated and emit infrared light with a wavelength of 630nm to 650nm.

[0039] The single continuous emission time of infrared light is 10 seconds as a standard working stage. After completing a 10-second irradiation stage, the device can perform cyclic operation according to the preset logic.

[0040] For example, in one embodiment, a manual cyclic start method is used. After the first 10-second exposure period, infrared light emission automatically stops. If the user feels that the itching is not completely relieved, they can operate the control switch again to start the next 10-second exposure period. In this way, the user can repeat multiple 10-second exposure periods according to their personal preference.

[0041] For example, in another embodiment, an automatic cycle mode is employed. Upon a single user activation, the device can automatically execute a complete treatment cycle consisting of multiple 10-second exposure phases. For example, the device may be configured to perform three consecutive 10-second exposure phases. Between each 10-second exposure phase, there may be a brief pause, for example, 2-5 seconds, during which the infrared light is turned off or its power is reduced. The device then automatically enters the next 10-second exposure phase, continuing until the predetermined number of cycles have been completed and the device automatically terminates.

[0042] For example, in another specific embodiment, infrared light can be continuously emitted, but every 10 seconds, a prompt is given to the user that a stage has been completed, such as a flashing indicator light or slight vibration. The user can decide whether to continue irradiation or stop based on this prompt.

[0043] Based on this, it helps to ensure sufficient but not excessive illumination of the mosquito bite area, avoiding discomfort that may be caused by the user forgetting to turn off the light or excessive continuous irradiation time.

[0044] On the one hand, staged irradiation may be more effective in activating certain biological reactions of the skin than single long-term irradiation, helping to achieve a more ideal itching relief and soothing effect.

[0045] On the other hand, it provides a clear reference for the user's usage duration, with simple operation and easy to master.

[0046] This kind of timing and cycle control function is usually realized by a micro control unit (MCU) or a dedicated timing integrated circuit (IC) built into the portable mosquito repellent device, controlling the on / off of the infrared LED lamp beads, the continuous light-emitting time, and the cycle logic through a preset program.

[0047] In order to further enhance the itching relief effect of the itching relief structure 2 and provide diversified relief means, the itching relief structure 2 further includes an electric heating component 203. The electric heating component 203 is used to relieve itching and discomfort by applying hot compress to the mosquito bite area.

[0048] The electric heating component 203 includes an electric control heating element.

[0049] In a specific embodiment, the electric control heating element is a ceramic heating sheet.

[0050] Among them, the electric control heating element is preferably arranged on a certain specific surface area of the portable mosquito repellent device main body 1, or on a certain surface of the ceramic heating sheet. This area is the hot compress working surface 2031, which is used to directly or indirectly contact the user's skin. Preferably, the hot compress working surface 2031 overlaps or partially overlaps with the area enclosed by the infrared light emitted by the infrared light emitting component 201 in the previous embodiment, and is located at the same end of the main body 1, that is, the treatment end.

[0051] For example, in a specific embodiment, the end surface of one end of the portable mosquito repellent device main body 1 is recessed inward to form a space for accommodating the electric control heating element, and the ceramic heating sheet is assembled in this space. On the annular wall surface enclosing to form this space, a light-transmitting structure 202 is provided, such as setting the annular wall surface to be transparent, or opening holes on the annular wall surface.

[0052] Generally speaking, in this embodiment, by combining the infrared light emitting component 201 suitable for emitting infrared light with the electric heating component 203 including the electric control heating element, and making the two act on the same treatment application area on the device main body 1 together, multi-dimensional physical itching relief combining the surface layer and the deep layer is realized, and the effect is more comprehensive and in-depth.

[0053] Among them, the electric heating component 203 (through the hot compress working surface 2031) mainly acts on the skin surface layer. The heat generated by the electric control heating element is directly transmitted to the skin surface, which can quickly increase the temperature of the epidermis and the superficial dermis in the bitten area. This surface heating effect can quickly degrade or denature and inactivate some itching-causing proteins remaining in the mosquito saliva, and promote the dilation of superficial capillaries and blood circulation. These effects mainly occur on the skin surface layer, aiming to achieve rapid and immediate itching relief.

[0054] Among them, the infrared light emitting component 201 (emitting infrared light) focuses on acting on the deep layer of the skin. The emitted infrared light with a specific wavelength has relatively good tissue penetration ability and can reach deeper skin layers than heat conduction (such as the dermis layer and even part of the subcutaneous tissue). The infrared light exerts its unique photobiomodulation effect in this deep layer area, such as reducing the local inflammatory reaction caused by the bite and promoting cell metabolism and repair processes. These effects help to solve the itching problem from a deeper and more fundamental level and may bring additional benefits of anti-inflammatory, detumescence, and accelerating healing, achieving an in-depth itching relief effect with the potential for conditioning and repair.

[0055] Therefore, the present invention combines the rapid effect on the surface layer by heating and the deep conditioning by infrared light to form a composite physical itching relief solution with complementary advantages and multi-dimensional effects. Compared with the devices in the prior art that only rely on a single physical method (only heating or only infrared light), the present invention can provide a more comprehensive and thorough itching relief effect and has stronger adaptability to itching caused by different reasons and at different depths.

[0056] In a specific embodiment, a temperature control component is provided. The temperature control component includes a temperature probe 205 and a control circuit. Specifically, the temperature control component mainly includes a temperature probe 205 and a control circuit.

[0057] Among them, the temperature probe 205 can be, for example, a thermistor, a PTC thermistor, a thermocouple, or an integrated temperature sensor IC. It is closely attached to or integrated near the hot compress working surface 2031 of the electric control heating element, or directly integrated inside or on the surface of the electric control heating element. Its function is to monitor the temperature of the hot compress working surface 2031 or the key points of the heating element itself in real time.

[0058] The control circuit usually has a microcontroller as the core, or is composed of a dedicated temperature control IC and peripheral components. The control circuit receives the real-time temperature signal from the temperature probe 205.

[0059] During operation, a target operating temperature range is preset in the control circuit. For example, a safe and effective temperature point such as 45°C, or an adjustable temperature range such as 40°C - 50°C. When the heating function is started, the control circuit adjusts the electric power supplied to the electrically controlled heating element through PWM (pulse width modulation) signals, switch on / off, or other means.

[0060] If the current temperature is lower than the set value, the control circuit will drive the heating element to heat up.

[0061] When the temperature probe 205 detects that the temperature reaches the preset upper limit or the target value, the control circuit will reduce the heating power or temporarily cut off the heating current to prevent the temperature from rising further. When the temperature drops slightly, the heating will be resumed in a timely manner, so as to accurately maintain the temperature of the hot compress working surface 2031 within the preset target range.

[0062] The control circuit usually also includes an independent over-temperature protection mechanism. If the temperature rises abnormally due to any fault and exceeds the set safety upper limit, the control circuit will immediately forcefully cut off the power supply to the heating element and may issue an alarm through an indicator light or a buzzer to ensure user safety.

[0063] As mentioned above, the temperature control component is often linked with the timing function. After reaching the preset single-time hot compress duration, such as 15 - 30 seconds, the heating function is automatically turned off, further enhancing safety and saving energy.

[0064] Through such a temperature control component, it can be ensured that the heating and itching relief function can not only reach an effective treatment temperature, but also strictly control the upper temperature limit, avoiding discomfort or burns to the user's skin, making the product safer and more reliable.

[0065] In a specific usage scenario, the temperature of the electrically controlled heating element is set to three gears.

[0066] The first gear (low temperature gear) has a set temperature of 40°C. The heat provided by this gear is relatively mild, mainly suitable for infants and young children with particularly delicate skin, or for adult users and body parts that are more sensitive to temperature, to ensure absolute safety and comfort.

[0067] The second gear (medium temperature gear) has a set temperature of 45°C. This gear is considered to be the conventional hot compress and itching relief temperature suitable for most adult users, which can provide significant thermal stimulation to effectively relieve itching while ensuring safety.

[0068] The third gear (high temperature gear) has a set temperature of 50°C. This gear provides a stronger sense of heat and is suitable for people with a higher tolerance to temperature, or in some cases, when users hope to quickly suppress a strong itching sensation through a higher temperature.

[0069] The user can select the desired temperature range through a dedicated range selection mechanism provided on the portable mosquito repellent device (for example, a button that can cycle through high, medium, and low ranges, or by short - pressing / long - pressing the same button to achieve different function switches, not shown in the figure) to select the desired temperature range. Once the user selects a certain range, the goal of the control circuit is to accurately maintain the temperature of the hot compress working surface 2031 near the set temperature value corresponding to that range.

[0070] Correspondingly, the infrared LED lamp beads can perform a running - light mode with different flashing frequencies or dynamic effects according to the above three ranges.

[0071] Specifically, when the user selects a specific temperature range of the electric heating component 203 through the range selection mechanism, not only will the electric heating component 203 operate according to the temperature parameters corresponding to that range, but at the same time, several infrared LED lamp beads will start a preset dynamic lighting mode, namely the running - light mode.

[0072] In this mode, the infrared LED lamp beads do not all light up constantly or simply flash synchronously at the same time, but light up, go out, or change brightness in turn according to a certain order and rhythm, forming a flowing light effect. More importantly, the dynamic characteristics of this running - light mode will vary according to the currently selected heating range, thus playing a role in intuitive indication and potential synergistic treatment.

[0073] For example, when the electric control heating element operates in the first range, the running - light mode of the infrared LED lamp beads will be the softest and have the lowest frequency. For example, the infrared LED lamp beads can very slowly light up one by one in sequence and then go out gently, forming a gentle and soothing chasing light ring, or the whole will change brightness in a breathing pattern at a relatively low frequency. The aim is to provide a non - glaring and gentle visual feedback, which is in line with the gentle treatment concept for sensitive populations in this range.

[0074] When the electric heating component 203 operates in the second range, the flashing frequency or flowing speed of the running - light mode will be moderate. For example, the chasing speed of the infrared LED lamp beads will be significantly faster than that in the first range, or the alternation of flashing will be more frequent, forming a clear and definite dynamic visual effect, indicating that the device is in the treatment state for regular adult use.

[0075] When the electric heating component 203 operates in the third range, the running - light mode will show the fastest, strongest, or most complex dynamic effect. For example, the infrared LED lamp beads will chase and flash at an extremely high speed, or present the effect of multiple groups of lamp beads flashing alternately quickly. This strong dynamic light effect clearly identifies the current highest heating range.

[0076] In a specific embodiment, the antipruritic structure 2 further includes a vibration component 204. The vibration component 204 is specifically used to generate mechanical vibrations, and achieves the purpose of interfering with, dispersing or suppressing the itchy feeling of the skin through physical stimulation, so as to realize physical antipruritic.

[0077] The core of the vibration component 204 can adopt common micro vibration motors in the field, such as eccentric rotor motors, linear resonant actuators, piezoelectric ceramic vibrators, etc.

[0078] The vibration component 204 is firmly installed inside the portable mosquito repellent device body 1, and the selection of its position takes into account that the vibration can be effectively transmitted to the device shell, especially to the treatment end for contacting the skin. For example, it is at the same end or near the hot compress working surface 2031 or the infrared light emission area, so that the user can clearly feel the vibration.

[0079] When the user feels itchy at the mosquito bite area, the vibration component 204 can be started. Then, the vibrating part of the portable mosquito repellent device is gently pressed on or near the itchy skin area. The mechanical stimulation generated by the vibration can be used for physical antipruritic.

[0080] In a specific embodiment, in order to ensure that each functional component inside the antipruritic structure 2, such as the infrared light emission component 201 including infrared LED lamp beads, the electric heating component 203 including an electric control heating element, the vibration component 204, and the control circuit for driving these components, can obtain stable and reliable power supply, preferably efficient contact power-on is adopted.

[0081] Reference Figure 2 As shown, in a specific embodiment of the present invention, in order to effectively manage the heat of the infrared light emission component 201, the antipruritic structure 2 further includes at least one phase change material unit 3. The phase change material unit 3 is specifically configured to be able to exchange heat with the infrared light emission component 201 to help stabilize the working temperature of the infrared light emission component 201.

[0082] The phase change material unit 3 mainly consists of two parts: a completely sealed container for containing the phase change material, and the phase change material itself filled inside the sealed container. The selection of the phase change material aims to utilize its characteristic of absorbing or releasing a large amount of latent heat and having a gentle temperature change when undergoing a phase change near a specific temperature point.

[0083] To achieve the heat exchange function, this sealed container forms direct physical contact with at least one component of the infrared light emitting component 201 or its adjacent area through its outer surface. For example, the sealed container can be closely attached to the circuit board, heat sink or its heat generating core area of the infrared light emitting component 201, ensuring that when the infrared light emitting component 201 generates heat during operation, or is affected by thermal radiation or heat conduction from other heat sources inside the device (such as the electric heating component 203), this heat can be effectively transferred to the phase change material unit 3. Through this direct contact configuration, the phase change material can absorb the excess heat of the infrared light emitting component 201, thereby buffering and regulating its temperature, helping to prevent the component from overheating, and maintaining its operation within a more optimal working temperature range, ensuring its performance and service life.

[0084] When the infrared light emitting component 201 and the electric heating component 203 stop working or their power significantly decreases, the temperature of themselves and the phase change material unit 3 is usually higher than other structures inside the device and the surrounding ambient air.

[0085] Therefore, the heat stored in the phase change material (at this time the phase change material is in a liquid state or partially liquid state) will be conducted through the wall of its sealed container to the internal structural components of the main body 1 that are in contact with it and have a lower temperature.

[0086] These structural components then transfer the heat to the air through natural convection with the air inside the main body 1. By providing heat dissipation holes or gaps in the main body 1, the hot air inside may also exchange with the external ambient air.

[0087] As Figures 4 to 7 shown, in this embodiment, the overall housing structure of the portable mosquito repellent device includes at least one first housing 101 and a second housing 102. These two housing parts can perform relative mechanical movement, enabling the user to drive either housing relative to the other from a separated state to a closely contacted state, or to return from the closely contacted state to the separated state.

[0088] Among them, when the first housing 101 and the second housing 102 are driven by the user to be in close contact with each other, the preset conductive terminals or electrical contacts located on their respective docking interfaces also engage reliably, thereby forming a complete electrical circuit.

[0089] At this time, the aforementioned contact power-on is established, connecting the main power supply to the entire itching relief structure 2 (including all its functional components and control circuits), enabling it to enter the standby or operable state.

[0090] Conversely, when the user drives the first housing 101 to separate from the second housing 102, these conductive terminals or electrical contacts are also disconnected, and the electrical circuit is cut off, thereby stopping the power supply to each component of the antipruritic structure 2.

[0091] For example, one or more spring pins or elastic contacts are provided on the docking surface of the first housing 101, and a matching conductive plane, pad or fixed contact is provided on the corresponding docking surface of the second housing 102. When the two housings are closed, the spring pins or elastic contacts contact the conductive areas of each other with a certain pressure to form a circuit. Correspondingly, a control switch 207 can be provided at the end of the second housing 102 to control the above-mentioned components to operate according to a set program.

[0092] Alternatively, a magnetic attraction-assisted alignment and contact method can also be adopted, that is, magnets that attract each other are provided at the docking parts of the two housings to assist the user in accurately aligning and keeping the two housings in contact, and at the same time the magnetic force can also ensure the contact pressure between the electrical contacts.

[0093] The portable mosquito repellent includes a container 103. The container 103 is used to hold a volatile liquid, such as a mosquito-killing liquid. It also includes a volatilization component 104, such as a volatilization rod, which is adapted to be inserted into the container 103 and is used to guide the volatilization of the mosquito-killing liquid. And it also includes an electric control heating component 105, which is used to apply heat to the volatilization component 104 to increase the diffusion efficiency of the mosquito-killing liquid.

[0094] Among them, the electric control heating component 105 can be inserted into the volatilization component 104 without contacting the inner wall surface of the volatilization component 104 to actively accelerate the diffusion of the mosquito-killing liquid.

[0095] Alternatively, the electric control heating component 105 is located outside the volatilization component 104 to actively accelerate the diffusion of the mosquito-killing liquid.
