Abstract
Description
Technical Field
[0001] This utility model relates to the field of sprayers, and more particularly to a vertical hot and cold sprayer. Background Technology
[0002] A sprayer is a mechanical device that disperses liquid into a mist. Sprayers primarily utilize pressure to propel liquid through tiny nozzles. Typically, a liquid pump generates pressure, delivering liquid from a reservoir to the nozzle. For example, in some small, manual sprayers, manually pressing a piston forces liquid in the reservoir under pressure, which is then expelled as droplets through the nozzle's orifices. In larger, electric or fuel-powered sprayers, an electric motor or engine drives the liquid pump, generating higher pressure, allowing the liquid to be sprayed at a greater flow rate and over a longer range.
[0003] Existing hot and cold mist beauty devices are simply heating sprays or directly spraying cold mist, with limited functionality, lacking adjustable settings, preheating, and heat preservation functions. While misting machines are frequently used in the medical field, existing models are relatively limited in function, poorly adaptable to different skin types, and the connection between the hot and cold spray nozzles and the atomizer in the device body results in bulky packaging, inconvenient transportation, and increased shipping costs. To address these technical problems, this application proposes a vertical hot and cold misting machine. Utility Model Content

[0030] reference Figure 4-6The beauty spray machine uses a cold spray atomizing plate 28 to atomize water from the cold water tank 27, which is then blown out through a spray nozzle by a fan 29. The microcontroller on the wiring board 31 controls the high, medium, and low speeds of the atomizing plate using PWM signals. This is mainly achieved by adjusting the duty cycle of the PWM signal. The specific working principle is as follows: PWM signal basics: PWM, or Pulse Width Modulation, is a method of digitally encoding analog signal levels. It controls the load by outputting a series of square wave pulse signals with different duty cycles. The duty cycle refers to the ratio of the high-level duration to the entire cycle. Control principle of the cold spray atomizing plate 28: Vibration frequency of the atomizing plate at high, medium, and low speeds: High speed: The frequency of the atomizing plate is usually around 1.5MHz-2.0MHz. At this frequency, the amount of water mist produced per unit time is relatively large, which can quickly replenish moisture to the skin. It is suitable for use when the skin is dry and needs rapid calming and soothing, or when a large area needs extensive hydration. For example, after sun exposure, when the skin is severely red, dry, and tight, the high-speed cold spray can be used for rapid emergency treatment. Medium setting: The atomizing plate frequency is generally between 1.2MHz and 1.5MHz. This frequency produces a moderate amount of water mist, providing a continuous and stable supply of moisture and soothing effect to the skin. It is suitable for daily cold spray treatments, such as when the skin feels slightly tight after cleansing, using the medium setting for routine calming and hydration. Low setting: The atomizing plate frequency is approximately 1.0MHz to 1.2MHz. This frequency produces a relatively small amount of fine water mist, suitable for sensitive and fragile skin that cannot withstand a large amount of water mist, or when only localized, mild hydration and calming are needed. For example, if the skin has mild allergic symptoms and only needs a small amount of cold mist for soothing, the low setting can be selected. High setting: When the cold spray atomizing plate is required to operate at the high setting, the beauty device's control circuit will output a PWM signal with a high duty cycle, such as 80% or even higher. This means that within each PWM cycle, the atomizing plate is energized for a longer period and de-energized for a shorter period. The cold atomizing plate 28 continuously receives a high-energy drive signal, causing its internal piezoelectric ceramic plate to vibrate at a high frequency and amplitude, rapidly and massively converting the liquid into water mist, thus achieving a large spray volume and strong atomization effect. Medium setting: At the medium setting, the duty cycle of the PWM signal output by the control circuit is moderate, such as around 50%. At this time, the energizing and de-energizing time of the cold atomizing plate 28 is approximately equal, the vibration frequency and amplitude of the piezoelectric ceramic plate are moderate, and the speed and amount of liquid conversion into water mist are also at a moderate level, producing a moderate spray volume and atomization effect. Low setting: At the low setting, the duty cycle of the PWM signal output by the control circuit is very low, such as 20% or lower. The energizing time of the cold atomizing plate 28 in each cycle is very short, the vibration frequency and amplitude of the piezoelectric ceramic plate are small, the speed and amount of liquid conversion into water mist are slow, thus achieving a smaller spray volume and weaker atomization effect.By changing the duty cycle of the PWM signal, the beauty device can precisely control the working state of the cold spray atomizing plate 28, realizing the adjustment of different levels of cold spray (high, medium, and low) to meet different user needs. Implementation method: Heating or preheating state function description with standby heat preservation: Preheating process: Circuit design: A heating control circuit based on a thyristor on the terminal board is designed, with the heating element connected in series with the thyristor in the power circuit. The microcontroller on the terminal board calculates the required heating power based on the set preheating temperature and the temperature detected by the current temperature sensor. Trigger angle control: During the preheating stage, the microcontroller outputs a trigger signal with a large duty cycle to the thyristor, keeping the thyristor conducting for most of the AC power cycle, allowing the heating element to obtain a high average voltage for rapid heating at high power, causing the internal temperature of the sprayer to rise quickly to near the set preheating temperature. Heat preservation process: Temperature monitoring and feedback: When the temperature approaches the set preheating temperature, the temperature sensor feeds back the real-time temperature signal to the microcontroller on the terminal board. Adjusting the firing angle: Based on the temperature deviation, the microcontroller reduces the firing angle of the SCR, shortening the conduction time of the SCR within the AC power cycle, thereby reducing the average power of the heating element and maintaining the temperature within the set insulation range. Stable insulation: Continuously monitoring the temperature and dynamically adjusting the SCR firing angle compensates for heat loss, ensuring the internal temperature of the sprayer remains stable at the insulation temperature.
[0031] Reference Figure 5-7 The system includes a lower water tank shell 19, with a junction box 31 installed at its front end. The junction box 31 houses a thermal spray thyristor and a microcontroller. A cold spray atomizing plate 28 is located at the bottom of the lower water tank shell 19. Multiple connecting pipes are installed on the left and right sides and the bottom of the lower water tank shell 19. A float with a 4mm thick magnetic ring is located on the left rear end of the lower water tank shell 19. A water cup lid 22 is located at the bottom of the lower water tank shell 19, inside the bottom wall of the shell. A heating element 23 is located at the bottom of the water cup lid 22, and a temperature sensor 30 is located on the outside of the heating element 23. The temperature sensor can detect the water temperature in real time. An upper water tank shell 20 is located at the top of the lower water tank shell 19. The upper water tank shell 20 has a junction box 31 installed at its front end. A fan 29 is installed at the front end of the upper shell 20 of the water tank. The fan has a speed of 2500 rpm and can reduce the temperature of the water mist processed by the atomizer. A water tank sealing ring 24 is provided on the side of the upper shell 20 and the lower shell 19 of the water tank. A Hall switch plate 25 is provided on the bottom rear end of the lower shell 19 of the water tank. Two Hall sensors are provided on the Hall switch plate 25, with a travel distance of 9 mm between them. When the float floats above the upper Hall sensor, it means that there is water. When the float floats below the lower Hall sensor, it means that there is no water. Since the two Hall sensors are spaced apart, the problem of false alarms can be effectively solved. A fixing block 26 is provided at the bottom of the Hall switch plate 25. The fixing block 26 is connected to the lower shell 19 of the water tank by bolts.
[0032] Reference Figure 4-6 The beauty spray machine features a hot spray function. It receives feedback signals from a temperature sensor 30, which are then processed by a microcontroller on a connector board 31 to control three power levels (high, medium, and low) via a thyristor. This control primarily adjusts the power of the heating element by controlling the thyristor's conduction angle, thus achieving different spray effects. The power level control principle is as follows: High level: In the high level, the controller sends a trigger signal to the thyristor's control electrode, ensuring the thyristor is almost fully conductive in each AC power cycle, with a conduction angle close to 180°. The hot spray atomization is achieved by the boiling rate of the water at different heating levels and the combination of ozone generated by the UV lamp with hot steam, producing a large amount of hot spray containing negative ions. The UV atomization principle: When the UV lamp is lit, it emits ozone, which combines with the boiling water vapor at high temperatures and decomposes into oxygen-rich, negative-ion-rich mist. As the heating temperature increases, the ozone decomposition rate accelerates. At temperatures exceeding 100°C, the decomposition becomes very rapid, beginning to convert into oxygen. At a high temperature of 270°C, it can immediately convert into a large amount of oxygen. The voltage applied to the heating element or fan 29 is almost a complete AC voltage waveform, allowing the load to obtain maximum power, thus achieving effects such as rapid heating to generate a large amount of steam or the fan 29 operating at high speed to spray a large amount of mist. Medium setting: In the medium setting, the controller adjusts the timing of the trigger signal so that the conduction angle of the thyristor within the AC power cycle is approximately 90°-120°. At this setting, the average voltage and power obtained by the load are between the high and low settings, resulting in a moderate heating speed or mist volume. Low setting: In the low setting, the controller makes the conduction angle of the thyristor very small, such as 30°-60°. Thus, within one AC power cycle, the thyristor is only in the conducting state for a short time, resulting in a lower average voltage and power obtained by the load, slower heating speed, or reduced mist volume. By changing the conduction angle of the thyristor, the beauty sprayer can precisely control the power of the load, achieving adjustments between high, medium, and low settings to meet the user's needs in different scenarios.
[0033] Working principle: For hot spray, first rotate the water cup 3 and remove it from the bottom of the water cup lid 22 to fill it with water. The water in the water cup 3 is heated by the heating tube 23, and the water temperature is monitored in real time by a temperature sensor. After heating, the water emits ozone when the UV lamp is lit. The ozone combines with the boiling water vapor and decomposes into oxygen mist, which is a negative ion mist. Inside the sealed water cup 3, water vapor continuously accumulates, increasing the internal pressure. When the pressure reaches a certain level, exceeding the external atmospheric pressure, the water vapor will be sprayed out as hot mist through the hot nozzle 11 under the pressure difference. For cold spray, water is taken out from the cold spray water tank 27 at the rear of the housing 1. The water is atomized by contacting the cold spray atomizing plate 28 at the bottom of the lower housing 19 of the water tank, and then blown out of the nozzle by the fan 29. Hot and cold spray are two independent working systems. Switching between hot and cold spray modes can be controlled by the cold spray button and hot spray button on the control panel 2. Cold spray: The atomizer turns the water in the cold spray tank into a mist, which, driven by the fan at three speeds (high, medium, and low), produces different amounts of cool, refreshing mist that is then sprayed out through the nozzle. Hot spray: A temperature sensor detects the water temperature and sends feedback to the microcontroller on the wiring board, which adjusts the heating element at three speeds (high, medium, and low). The three heating speeds adjust the evaporation rate of the water to produce hot mist, thus regulating the spray volume.
