Description

Technical Field

[0001] This utility model relates to the field of facial steamer technology, and more specifically, to a distance-sensing anti-scalding facial steamer device. Background Technology

[0002] With the advancement of technology in the beauty and skincare field, facial steamers, as devices for deep facial cleansing and hydration, have widely entered the consumer market. Current facial steamers typically use heating elements to vaporize liquid in a reservoir, and then use micro-air pumps or other air delivery devices to transport the high-temperature steam to the nozzles, which are then directed to the user's facial area. Their working principle is based on the thermal effect of the steam promoting pore dilation, while the nano-sized water molecules it carries can penetrate the stratum corneum to achieve moisturizing.

[0003] However, existing facial steamers require the steam generator to maintain a temperature above 100°C to ensure continuous vaporization efficiency, resulting in high steam temperatures at the nozzle outlet. Therefore, users must maintain a safe distance to avoid the risk of burns. However, this distance causes the steam energy to decrease during diffusion, making it difficult to control the effective temperature applied to the face. If the distance is too far, the temperature is too low, making it difficult to achieve the desired deep pore cleansing effect. If the distance is too close, the steam temperature can easily rise suddenly, causing facial burns. Therefore, a facial steamer that dynamically adjusts the steam temperature based on the distance is needed to solve this problem. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a distance-sensing anti-scalding facial steamer to solve the aforementioned problems.

[0005] This utility model is implemented as follows: A distance-sensing anti-scalding facial steamer includes a housing. Inside the housing, from bottom to top, are a first partition and a second partition, which divide the interior into a water tank at the bottom, a misting chamber in the middle, and a mixing chamber at the top. The misting chamber includes a central air duct disposed between the first and second partitions, connecting the misting chamber and the mixing chamber. A steam nozzle communicating with the mixing chamber is located at the top of the housing. An infrared distance sensor is located on the outer side of the mixing chamber near the opening of the steam nozzle. A microcontroller is also located inside the misting chamber.

[0006] Furthermore, the atomization chamber includes a hot atomization pool, four cold atomization pools, and a blowing chamber distributed along the central air duct. The hot atomization pool, the cold atomization pool, and the blowing chamber are respectively connected to the side wall of the central air duct. The top of the central air duct extends through to the mixing chamber. The volume of the hot atomization pool is twice the volume of the cold atomization pool.

[0007] Furthermore, the blowing chamber includes a fan disposed near the inner wall of the outer casing, a first air outlet is provided on the outer casing near the fan, and a second air outlet is provided on the outer bottom of the central air duct near the blowing chamber.

[0008] Furthermore, a mezzanine space is provided above the air blowing chamber via a partition, and the microcontroller is disposed in the mezzanine space.

[0009] Furthermore, the atomization chamber is equipped with a water control valve, the inlet of which is connected to the water tank via a pipe. The atomization chamber is also equipped with a water level gauge and a heating unit. A water vapor outlet is provided on the side wall of the central air duct near the top of the atomization chamber.

[0010] Furthermore, the water vapor outlet is inclined, with the inclination direction being the side of the inner side of the thermal atomization pool facing the top of the central air duct.

[0011] Furthermore, the cold atomization pool is equipped with the same water control valve, water level gauge and water vapor outlet as the hot atomization pool, and an atomization generator is installed inside the cold atomization pool.

[0012] Furthermore, a steam mixing impeller is provided inside the mixing chamber, a first support is provided above the central air duct inside the mixing chamber, and a second support extending laterally is provided on the inner side wall of the mixing chamber. The steam mixing impeller is movably disposed between the first support and the second support.

[0013] Furthermore, an indicator light is provided on the outside of the mixing chamber near the lower part of the infrared ranging sensor.

[0014] Furthermore, the microcontroller is electrically connected to the water level gauge, the water control valve, the atomizer, the heating unit, the fan, the indicator light, and the infrared ranging sensor, respectively.

[0015] The beneficial effects of this invention are as follows: It collects real-time facial distance data from the user via an infrared ranging sensor and transmits it to a microcontroller. The microcontroller dynamically adjusts the number of cold mist pools that start and stop based on a preset distance threshold. When a user is detected approaching, the system automatically increases the cold mist output. Hot and cold steam are thoroughly mixed in the mixing chamber via a central duct, and the homogenization effect is enhanced by the rotation of a steam mixing impeller. The final output is composite steam with a temperature controlled within a safe range. This device innovatively constructs a three-level temperature control protection system: the first level uses distance monitoring for front-end early warning; the second level uses dynamic ratios of hot and cold steam for mid-range adjustment; and the third level uses a mixing impeller to ensure uniform steam at the end. Through a dual mechanism of infrared ranging and cold mist compensation, the risk of burns is reduced. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] like Figures 1-3 As shown, this utility model provides a distance-sensing anti-scalding facial steamer, including a housing 10. Inside the housing 10, from bottom to top, are respectively provided a first partition 11 and a second partition 12, which divide the interior of the housing 10 into a water tank 14 at the bottom, an atomizing chamber 17 in the middle, and a mixing chamber 15 at the top. The atomizing chamber 17 includes a central air duct 13 disposed between the first partition 11 and the second partition 12, connecting the atomizing chamber 17 and the mixing chamber 15. A steam nozzle 16 is disposed at the top of the housing 10, communicating with the mixing chamber 15. An infrared ranging sensor 20 is installed on the side near the opening of the steam nozzle 16. A microcontroller 1804 is also installed in the atomization chamber 17. This solution reduces the temperature of the hot mist by opening different numbers of cold atomization pools 1701. In actual use, the infrared ranging sensor 20 monitors the distance between the user's face and the facial steamer in real time. The closer the distance, the more cold atomization pools 1701 are opened to ensure that there will be no burns at close range. When the distance is far, the number of cold atomization pools 1701 is reduced to ensure that the heat of the hot mist can reach the expected temperature when it reaches the user's face.

[0022] like Figure 3 As shown, the atomization chamber 17 includes a hot atomization pool 1702, four cold atomization pools 1701 and a blowing chamber 18 distributed along the central air duct 13. The hot atomization pool 1702, the cold atomization pools 1701 and the blowing chamber 18 are respectively connected to the side wall of the central air duct 13, and the top of the central air duct 13 extends through to the mixing chamber 15.

[0023] Furthermore, the air chamber 18 includes a fan 1802 disposed near the inner wall of the outer casing 10, a first air outlet 1801 opened on the outer casing 10 near the fan 1802, and a second air outlet 1301 opened on the outer bottom of the central air duct 13 near the air chamber 18.

[0024] As a preferred embodiment, the first air vent 1801 is a square channel opened on the outer casing 10. A dust filter device is detachably installed in the square channel to prevent external airflow from bringing dust and other objects into the interior of the facial steamer, causing the hot mist to pollute the user's face and creating an unpleasant impression. At the same time, the detachable installation facilitates regular replacement and prevents secondary pollution problems caused by long-term use.

[0025] The dust filter device is a filter screen.

[0026] like Figure 2 As shown, a mezzanine space 1803 is provided above the air blowing chamber 18 via a partition. The microcontroller 1804 is located in the mezzanine space 1803. The mezzanine space 1803 also contains a control circuit and a power line extending to the outside. This circuit part is a conventional technical means, so it is not marked in the figure.

[0027] In this embodiment, a water control valve 1704 is installed inside the atomization chamber 17. The inlet of the water control valve 1704 is connected to the water tank 14 through a pipe. A water level gauge 1703 and a heating unit 1706 are also installed inside the atomization chamber 17. A water vapor outlet 1707 is opened on the side wall of the central air duct 13 near the top of the atomization chamber 17. It should be noted that the water level gauge 1703 is equipped with two thresholds. The first threshold is the water replenishment threshold, and the second threshold is the water full threshold. When the microcontroller 1804 detects the first threshold signal, it controls the water control valve 1704 to open and draw water from the water tank 14 to replenish water. When the second threshold is triggered, the water replenishment stops.

[0028] In this embodiment, the water vapor outlet 1707 is inclined, with the inclination direction being the side where the inner side of the thermal atomization pool 1702 faces the top of the central air duct 13. This inclination facilitates the airflow from the blowing chamber 18 towards the central air duct 13 to blow these steams towards the mixing chamber 15, preventing the flow diversion phenomenon and thus affecting the formation of hot fog in the thermal atomization pool 1702.

[0029] In this embodiment, the cold atomizing pool 1701 is equipped with the same water control valve 1704, water level gauge 1703 and water vapor outlet 1707 as the hot atomizing pool 1702, and the cold atomizing pool 1701 is equipped with an atomizing generator 1705.

[0030] In this embodiment, the volume of the hot atomizing pool 1702 is twice the volume of the cold atomizing pool 1701. Since the main function of this facial steaming device is to perform hot steaming, that is, the hot atomizing pool 1702 is the main working unit, it needs to generate a large amount of hot mist. At the same time, the number of times the water in the hot atomizing pool 1702 is replenished should be reduced to avoid the temperature dropping after water replenishment, which would result in too frequent intervals of hot mist generation and affect the user experience.

[0031] In this embodiment, a steam mixing impeller 1502 is provided inside the mixing chamber 15. A first support 1501 is provided above the central air duct 13 inside the mixing chamber 15. A second support 1503 extending laterally is provided on the inner side wall of the mixing chamber 15. The steam mixing impeller 1502 is movably disposed between the first support 1501 and the second support 1503. Since the cold mist and hot mist converge at the top end of the central air duct 13 and the internal space of the mixing chamber 15 is small, the mixing is not sufficient, which leads to instability in the way the mist blows onto the user's face. After the steam mixing impeller 1502 is installed at the air outlet of the central air duct 13, the steam mixing impeller 1502 is rotated by the cold mist and hot mist, thereby increasing the mixing effect and solving the problem of insufficient mixing.

[0032] In a preferred embodiment, an indicator light 19 is provided on the outside of the mixing chamber 15, near the infrared ranging sensor 20. The distance to the user detected by the infrared ranging sensor 20 is divided into stages, with each stage represented by a different color of the indicator light 19. Each stage corresponds one-to-one with the number of cold atomizing pools 1701. Taking the four cold atomizing pools 1701 in this embodiment as an example, as the user moves closer to the facial steamer, the indicator light 19 changes color sequentially from red to orange to yellow to blue to green. The specific rules are as follows: When the red light is on, the user is furthest away. To ensure that the hot mist is stable enough when it reaches the user's face, all four cold misting pools 1701 stop generating cold mist. Orange light, activates a cold atomization pool 1701; Yellow light, activate two cold atomization pools 1701; Blue light, activate three cold atomization pools 1701; Green light, turns on the cold atomization pool 1701.

[0033] It should be noted that the core function of indicator light 19 is to warn the user of the temperature range of steam nozzle 16, so as to prevent them from rashly approaching the steam nozzle 16 when it is in the red light state and causing burns.

[0034] like Figure 4 As shown, the microcontroller 1804 is electrically connected to the water level gauge 1703, the water control valve 1704, the atomizer 1705, the heating unit 1706, the fan 1802, the indicator light 19, and the infrared ranging sensor 20.

[0035] Specifically, based on the distribution of the cold atomizing pool 1701 and the hot atomizing pool 1702, the microcontroller 1804 dynamically adjusts the number of cold atomizing pools 1701 that are turned on according to the user distance monitored by the infrared ranging sensor 20, thereby adjusting the temperature of the hot mist so that the hot mist is in a suitable temperature range when it reaches the user's face. Through the above structure, the problem that the effect of the existing facial steamer is affected by the distance between the user's face and the nozzle is that the effect is poor when the face is too far away and easy to burn when the face is too close is solved.

[0036] It should be noted that the specific models and specifications of the microcontroller 1804, water level gauge 1703, water control valve 1704, atomizer 1705, heating unit 1706, fan 1802, indicator light 19 and infrared ranging sensor 20 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The power supply and operating principle of the microcontroller 1804, water level gauge 1703, water control valve 1704, atomizer 1705, heating unit 1706, fan 1802, indicator light 19 and infrared ranging sensor 20 are clear to those skilled in the art and will not be described in detail here.

[0038] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
