Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of humidifiers, and in particular to an air humidifier Background Art
[0002] Commonly used air humidifiers usually use ultrasonic atomization or evaporative atomization to humidify the air.
[0003] Among them, ultrasonic atomization is widely used in daily humidification products. It has the effects of high conversion efficiency, no need for heating, no consumables, and energy saving. However, due to the limitation of the frequency of the transducer device, the atomized particles are large, and obvious white mist can be seen. There are many technical defects in the use process. Conventional ultrasonic atomizers have obvious white mist, and the atomized particles are large, generally composed of water particles larger than 3 microns. After the water particles come out of the atomizer, they need to be vaporized in the air to achieve a real improvement in the air humidity. Due to the large particle size, the speed of vaporization and diffusion in the air is limited, resulting in poor humidity balance, which can easily cause the humidity around the atomizer to be too high, reach saturation, and form secondary condensation problems.
[0004] Ordinary evaporative humidifiers, whether hot mist or cold mist mode, have obvious technical defects. Hot mist humidifiers, because they need to use heating evaporation, have low conversion efficiency and high energy consumption. In order to increase the surface area of the liquid, cold mist humidifiers usually use water curtains or similar structures to increase the contact area between water and air, thereby improving the efficiency of evaporation or vaporization. However, this method is prone to scale and bacterial growth on the water curtain or similar structure. At the same time, increasing the contact area will limit the volume of the product, which is not conducive to the development of product miniaturization. Summary of the invention

[0031] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0032] like Figure 1 As shown, the air humidifier of the present invention includes an evaporative humidifying component 1, an atomizing humidifying component 2, and a humidifying air flow channel 3. The evaporative humidifying component 1 and the atomizing humidifying component 2 are both connected to the humidifying air flow channel 3. In some embodiments, the evaporative humidifying component 1 is arranged above the atomizing humidifying component 2. The atomizing humidifying component 2 atomizes the water in the water tank 24 into particles to increase its contact area with the air. The evaporative humidifying component 1 uses high-speed air flow to quickly vaporize the water particles.
[0033] like Figure 1 As shown, the evaporative humidification component 1 is provided with a first pneumatic device 11, and the first pneumatic device 11 is provided with an air outlet 12, and the air outlet 12 is connected to the humidification air flow channel 3. In some embodiments, a heating device 14 is provided between the first pneumatic device 11 and the air outlet 12 to heat the air, increase the air pressure difference and heat the air, and improve its vaporization efficiency. In some embodiments, the first pneumatic device 11 is connected to a first air duct 13, and the first air duct 13 is connected to the air outlet 12. The heating device 14 is provided in the first air duct 13. The setting of the first air duct 13 stabilizes the air pressure and airflow area at the air outlet 12, so that the vaporization effect is better and more stable.
[0034] like Figure 1 As shown, the atomizing humidifying component 2 is provided with a water tank 24, an atomizer 27, a second pneumatic device 28, and a mist outlet 26. The atomizer 27 atomizes the water in the water tank 24, and the second pneumatic device 28 accelerates the air flow above the water tank 24. The mist outlet 26 is connected to the humidifying air flow channel 3. In some embodiments, the atomizing humidifying component 2 is provided with a shell 21, a water tank 24 is provided in the shell 21, a receiving chamber 25 is provided below the water tank 24, and an inner chamber 22 is provided above the water tank 24, and the inner chamber 22 is surrounded by the surface of the water tank 24 and a plurality of side walls 23. The atomizer 27 and the second pneumatic device 28 are arranged in the receiving chamber 25. In some embodiments, the atomizer 27 is an ultrasonic atomizer 27, which is arranged at the bottom of the water tank 24, and the water in the water tank 24 is atomized by the vibration of the ultrasonic atomizer 27. The mist outlet 26 is disposed on a side wall 23 of the inner cavity 22 . In some implementations, the mist outlet 26 is disposed on an upper side wall 23 of the inner cavity 22 .
[0035] like Figure 1As shown, the humidification air flow channel 3 is provided with an air outlet component 31, the wind direction of the air outlet 12 forms an angle with the wind direction of the mist outlet 26 and converges the air flow at the air outlet component 31, and the wind speed at the air outlet 12 is greater than the wind speed at the mist outlet 26, the converged airflow vaporizes, and is led out into the air through the air outlet component 31 for air humidification. Due to the pressure difference between the air outlet 12 and the mist outlet 26, the converged airflow will produce a Venturi effect, which reduces the air pressure at the mist outlet 26 and in the inner cavity 22, increases the saturation difference, and accelerates the vaporization speed, so that the mist led out of the mist outlet 26 is vaporized. The setting of the air outlet component 31 ensures that the converged airflow can evaporate and vaporize well, thereby improving the vaporization efficiency of the device.
[0036] like Figure 1 As shown, the evaporative humidification component 1 also extends a guide plate 15 at the air outlet 12, near the mist outlet 26, toward the humidification air flow channel 3, and the guide plate 15 extends toward the air outlet component 31. This prevents the airflow at the air outlet 12 from passing through the mist outlet 26 too much into the inner cavity 22 due to the pressure difference, thereby affecting the efficiency of vaporization and the effect of humidification. At the same time, the mist at the mist outlet 26 is also guided to be discharged toward the air outlet component 31, fully mixed with the airflow discharged from the air outlet 12, and vaporized.
[0037] In some embodiments, such as Figure 1 As shown, the second pneumatic device 28 is arranged in the inner cavity 22 or at the bottom of the water tank 24, and the wind of the second pneumatic device 28 is directed into the inner cavity 22, accelerating the flow of the airflow in the inner cavity 22, so that the mist is directed to the humidification airflow channel 3 through the mist outlet 26. The wind direction of the second pneumatic device 28 can be set as required. In some embodiments, the wind direction of the second pneumatic device 28 is parallel to the surface of the water tank 24, which can better balance the airflow in the inner cavity 22 and make the mist particles more stable.
[0038] In some embodiments, such as Figure 1As shown, the second air moving device 28 is arranged at the bottom of the water tank 24, arranged in the accommodating chamber 25, and the wind is led out of the surface of the water tank 24 through the second air duct 281 of the second air moving device 28. In some embodiments, the air duct opening 282 of the second air duct 281 is opened in the direction of the side wall 23 away from the mist outlet 26, and the wind of the air duct opening 282 is led out to the side wall 23, and the wind direction of the air duct opening 282 is parallel to the surface of the water tank 24. The wind of the air duct opening 282 is led out to the side wall 23, and the side wall 23 diffuses the wind upward and in the opposite direction of the outflow, so that the wind is fully diffused in the inner cavity 22, accelerating the airflow in the inner cavity 22, and ensuring the stability of the airflow, ensuring a better atomization effect, and avoiding secondary condensation of part of the mist in the inner cavity 22 or the continuous increase of the atomized particles.
[0039] In some embodiments, such as Figure 1 As shown, the humidification air flow channel 3 is a vaporization channel. In order to better achieve vaporization, the air outlet 12 is set to be multiple, and the mist outlet 26 is set to be multiple, which can be combined arbitrarily to increase the atomized particles and air flow, and further accelerate the evaporation speed.
[0040] The working principle of the air humidifier in this embodiment is to use the ultrasonic transducer atomizer to vibrate and generate energy to atomize water to form water particle mist beads of 3 to 10 microns in size, increase the surface area of the liquid, and the second pneumatic device 28 passes the atomized particles through the inner cavity 22 to the mist outlet 26 and enter the humidification air flow channel 3. The first pneumatic device 11 forms a separate high-speed air duct, the wind speed of the air outlet 12 is greater than the wind speed of the mist outlet 26, the airflow of the air outlet 12 and the airflow of the mist outlet 26 converge on the humidification air flow channel 3, and the high-speed airflow of the air outlet 12 is used to vaporize the atomized particles guided out of the mist outlet 26, so that the airflow after convergence on the humidification air flow channel 3 enters the air guide component 31 for full vaporization. The air guided out on the air guide component 31 is a vaporized humidified gas, which meets the effect of high humidity and no obvious atomized particles, thereby realizing rapid humidification of the air.
[0041] The air humidifier in this embodiment makes full use of various elements of evaporation to maximize the humidification efficiency without producing adverse effects or consumables.
[0042] The factors that generally affect evaporation are temperature, humidity, liquid surface area, and air flow rate on the liquid surface. Under relatively static conditions, the evaporation rate of water only depends on the molecular diffusion rate, and the evaporation rate W is described by the following equation:
[0043]
[0044] The above formula is called Dalton's law, which shows that the evaporation rate W is proportional to the saturation difference (Ee) and the molecular diffusion coefficient (A), and inversely proportional to the air pressure (P). The saturation difference (Ee), at a certain temperature, the difference between the saturated water vapor pressure (E) and the actual water vapor pressure (e) in the air, is called the saturation difference (d). That is, d = Ee. It indicates the degree of saturation of the actual water vapor in the air. It is often used in the study of water surface evaporation. Its size can indicate the evaporation capacity of water molecules. The larger d is, the stronger the evaporation capacity and the faster the speed.
[0045] In some embodiments, various factors affecting evaporation are fully utilized by combining structures and principles, so that the evaporation efficiency is greatly improved.
[0046] The atomization part is used to increase the surface area of the liquid and speed up the evaporation rate. The liquid is atomized into liquid particles with a diameter of 3 to 10um, so that the surface area of the liquid is increased. According to the container area of a conventional humidifier, taking a diameter of 20cm as an example, referring to the atomization volume of 700mL / H, and the average particle diameter of 5um, the surface area of the atomized particles is increased by about 10,000 times compared with the surface area of the liquid surface, which greatly speeds up its evaporation rate and creates powerful conditions for vaporization.
[0047] By using the high-speed air duct (first air duct 13), the air flow speed on the liquid surface can be increased to improve its evaporation speed. At the same time, the air pressure in the inner cavity 22 of the mist outlet 26 is reduced, so that the saturation difference of the humidification air flow channel 3 is increased, and the vaporization efficiency and evaporation speed in the humidification air flow channel 3 are accelerated.
[0048] The heating device 14 is used to increase the temperature in the first air duct 13, so that the temperature entering the humidified air flow channel 3 is increased, and the evaporation rate in the humidified air flow channel 3 is accelerated, so that the mist discharged from the mist outlet 26 is fully vaporized after passing through the humidified air flow channel 3 and the air discharge component 31. The airflow discharged through the air discharge component 31 is humidified gas without obvious atomized particles, and can quickly diffuse into the air and humidify the air.
[0049] At the same time, the humidified air flow channel 3 is provided with an air outlet component 31, so that the atomized particles can be fully vaporized in the channel, so that the final air has sufficient humidity but does not contain too many water particles.
[0050] On the other hand, a humidification method of an air humidifier, such as Figure 2 As shown, including:
[0051] Step 1 The atomizer 27 atomizes the water in the water tank 24 to generate mist, thereby increasing the surface area of the liquid and accelerating the evaporation rate.
[0052] Step 2: The first pneumatic device 11 generates a high-speed airflow, which enters the humidification airflow channel 3. The air flow speed on the liquid surface can be increased to improve its evaporation speed.
[0053] Step 3: The second pneumatic device 28 guides the mist out and enters the humidification airflow channel 3 to converge with the high-speed airflow, and the mist is vaporized into gas. The converged airflow, due to the pressure difference between the air outlet 12 and the mist outlet 26, that is, there is a certain wind speed difference and pressure difference between the high-speed airflow generated by the first pneumatic device 11 and the mist generated by the second pneumatic device 28, will produce a Venturi effect, reduce the air pressure at the mist outlet 26 and in the inner cavity 22, increase the saturation difference, and accelerate the vaporization speed, so that the mist guided out of the mist outlet 26 is vaporized.
[0054] Step 4: The vaporized gas enters the air outlet component 31 for full vaporization, and then enters the air to humidify the air. The arrangement of the air outlet component 31 ensures that the converged airflow can be evaporated and vaporized well, thereby improving the vaporization efficiency of the device.
[0055] Preferably, the wind speed of the high-speed airflow generated by the first pneumatic device 11 at the air outlet 12 is greater than the wind speed of the second pneumatic device 28 in directing the mist to the mist outlet 26 .
[0056] Preferably, the atomizer 27 is an ultrasonic atomizer 27, which is disposed at the bottom of the water tank 24, and uses the energy generated by the vibration of the transducer atomizer sheet in the ultrasonic atomizer 27 to atomize the water. In other embodiments, the atomizer 27 may be of other types, and is not limited to being disposed at the bottom of the water tank 24.
[0057] Preferably, the air outlet 12 is provided with a guide plate 15 near the mist outlet 26, and the guide plate 15 extends into the humidification air flow channel 3 in the direction of the air outlet component 31, so that there is an air pressure difference between the air outlet 12 and the mist outlet 26, thereby accelerating the efficiency of vaporization.
[0058] Preferably, a first air duct 13 is provided between the first pneumatic device 11 and the air outlet 12, and a heating device 14 is provided on the first air duct 13 to heat the airflow of the first air duct 13. By heating, the evaporation speed is accelerated, so that the particle size of the humidified gas entering the air is smaller, the diffusion speed is faster, and the humidity balance in the air is better.
[0059] In summary, the air humidifier of the present invention utilizes the atomizing humidifying component 2 to atomize the water in the water tank 24 into particles, thereby increasing its contact area with the air and accelerating its evaporation rate. At the same time, the evaporative humidifying component 1 is used to rapidly vaporize the water particles by utilizing high-speed air flow, so that the airflow derived through the air derivation component 31 is a humidified gas that can quickly diffuse in the air and humidify the air. At the same time, the humidification speed of this type of air humidifier is fast, and the humidified air has a good humidity balance, and will not produce secondary condensation, giving people a stronger sense of comfort. In addition, this type of air humidifier has a simple structure and is easy to develop in miniaturization. At the same time, it has low power consumption and saves costs. It is an environmentally friendly and economical product that meets the needs of the public.
