Description

Technical Field

[0001] The invention belongs to the field of air conditioning, and in particular relates to a humidifier. Background Art

[0002] Compared with other humidifiers, such as evaporative humidifiers, ultrasonic humidifiers have the advantages of small size, high humidification intensity, low power consumption, and good control performance. Therefore, they are widely used in household humidifiers with high power. However, the range of action of ultrasonic humidifiers is small, and fans are generally required to expand the effective action radius. Moreover, fans can make the atomization more uniform. Therefore, many high-power humidifiers are matched with larger fans. Fans can prevent heatstroke and cool down. Therefore, the fans of some ultrasonic humidifiers are set at a higher position, and the water tank of the humidifier is generally set at a lower position to lower the center of gravity. In this way, the distance between the ultrasonic atomizer and the fan is far, and it is usually necessary to use a closed pipe to transport the atomized fluid to the fan position. In this way, a large amount of atomized fluid contacts the inner wall of the pipe and condenses into water droplets, which reduces the efficiency of atomization. For example, the Chinese patent publication number "CN115853801A" is named "an improved floor fan with fixed mist guide pipe", which discloses a mist guide pipe structure, and its pipe is relatively curved, which is easy to produce a large amount of condensed water, reducing the atomization efficiency.

[0003] In addition, in order to make the atomized fluid flow faster, a separate small fan is needed to assist the fluid flow. However, the waterproof performance of small fans is generally poor. Therefore, in order to prevent the atomized fluid from entering the area of ​​the small fan, the channel from the small fan to the atomization channel is generally designed to be a more curved shape. In this way, there is a large amount of turbulence in the airflow blown by the small fan, which will also generate a large amount of turbulence in the atomized fluid after reaching the atomized fluid. In this way, the atomized fluid will have a large amount of irregular flow and collide with the inner wall of the pipe, which will increase the condensed water droplets and further reduce the atomization efficiency.

[0004] like Fig.11 As shown, some existing ultrasonic humidifiers are provided with an atomization chamber 1 and an atomization channel 2. There are two defects: the atomization channel 2 is curved, so the atomized fluid 12 flows in the atomization channel 2 and collides with the inner wall for many times; the small fan 10 is provided to generate lateral flow air 11, making the atomized fluid 12 flow more chaotically and more likely to contact with the inner wall of the atomization channel 2. The direction of the arrow in the figure indicates the direction of fluid flow. Multiple collisions of the atomized fluid 12 will make the atomization efficiency lower.

[0005] Chinese patent publication number "CN108397849A" and the patent name "A kind of atomizing humidifier with circular air inlet" discloses a humidifier with circular air inlet. Although it partially solves the technical problem of the second point mentioned above, the air is blown vertically into the atomized fluid near the atomizing generator. Although it is easier to mix with the atomized fluid, it also produces more turbulence, which is not conducive to the long-distance transportation of the atomized fluid. It is easy to contact and condense with the inner wall of the atomizing channel. In addition, since the atomizing channel is short and straight, it does not consider the technical problem of how to transport the atomized fluid in the atomizing channel. Therefore, when this technical solution uses a curved atomizing channel, under the action of inertia, many atomized fluids will collide with the inner wall of the atomizing channel to produce a large number of condensed water droplets, reducing the working efficiency of the humidifier.

[0006] Chinese patent publication number "CN206755467U" and patent name "A Humidifier" discloses a humidifier having the same technical problem and is not suitable for use in longer or curved channels. Summary of the invention

[0007] In view of the above-mentioned prior art, an object of the present invention is to provide a humidifier with higher atomization efficiency, so as to reduce condensation of atomized fluid in the atomization channel.

[0008] The technical solution of the present invention is implemented as follows: a humidifier includes an atomization chamber and an atomization channel, the atomization channel is arranged above the atomization chamber, the atomization chamber and / or the atomization channel are evenly distributed or surrounded by an air flow channel, the air flow channel is provided with an air inlet and an air outlet, the air inlet is located outside the atomization chamber and the atomization channel, the air outlet is located inside the atomization chamber and / or the atomization channel, the air outlet opening is inclined upward or vertically upward and is parallel or nearly parallel to the axial direction of the atomization channel, and an angle within the range of 10 degrees is considered to be parallel.

[0009] The beneficial effect of such design is: an atomizing structure is provided in the atomizing chamber to atomize water, and the atomized fluid will rise from the atomizing chamber to the atomizing channel under the action of inertia or airflow. As the atomized fluid in the atomizing chamber and the atomizing channel flows, a pressure difference is formed between the air inlet and the air outlet or the pressure difference is expanded, so that a large amount of air reaches the air outlet from the air inlet and enters the atomizing chamber or the atomizing channel. Since the atomizing chamber and / or the atomizing channel are evenly distributed or surrounded by the air flow channel, the air outlet also needs to be evenly distributed or surrounded by the atomizing chamber and / or the atomizing channel. After the air enters the atomizing chamber and / or the atomizing channel, most of it flows along the inner wall of the atomizing chamber and / or the atomizing channel, so that the atomized fluid can be isolated from the inner wall of the atomizing channel by air, reducing the direct collision between the atomized fluid and the inner wall. Especially for high-power humidifiers, it can avoid a large amount of atomized fluid from contacting the atomizing channel, reduce the condensation rate of the atomized fluid, and significantly improve the working efficiency of the humidifier.

[0010] Furthermore, multiple air inlet pipes are evenly distributed in the circumference of the atomization chamber and / or the atomization channel, and the air outlets of the air inlet pipes are evenly distributed in an annular manner on the inner wall of the atomization chamber or the atomization channel. The air outlet of the air inlet pipe is close to the inner wall of the atomization chamber or the atomization channel or directly abuts against the inner wall. The closer the distance, the higher the space utilization rate. As a preferred embodiment, it can be designed as an S-shaped tube, and a drainage groove is provided at the lower end of the S-shaped tube. A pressure-stabilizing hole is provided on the side wall of the S-shaped tube. The pressure-stabilizing hole can stabilize the pressure difference on both sides to ensure that the fluid flow is more stable. The air inlet pipe can also be designed as a straight pipe, but if it is designed outside the atomization chamber, the space is relatively limited. The straight pipe can penetrate from the bottom of the atomization chamber into the atomization chamber. The structure is simple and the flow resistance is small.

[0011] Furthermore, an annular air duct is provided on the circumference of the atomization chamber and / or the atomization channel, and the air outlet of the annular air duct is arranged along the inner wall of the atomization chamber or the atomization channel. In this way, as the air flows, it is equivalent to generating a gas protection layer on the inner wall of the atomization channel, thereby preventing a large amount of atomized fluid from contacting the inner wall of the atomization channel, reducing water droplets condensed on the inner wall of the atomization channel, and improving the atomization efficiency.

[0012] Furthermore, the air inlet is connected to a chamber provided with a small fan and the small fan can generate a positive pressure airflow, which can generate a stable airflow, better isolate the atomized fluid in the atomization channel, further increase the flow speed of the atomized fluid, and improve the atomization efficiency.

[0013] Furthermore, a large fan is provided at the mist outlet of the atomizing channel so that the rotation of the large fan accelerates the gas flow, thereby reducing the pressure of the atomizing channel to form a negative pressure. The negative pressure can be used to increase the pressure difference and accelerate the flow of the atomized fluid in the atomizing channel.

[0014] Furthermore, the shape of the cross-section of the atomization channel transitions from a circle to an approximate rhombus or shuttle shape. During the atomization fluid delivery process, the surface area of ​​the circle is the smallest under the same flow rate, which can minimize the contact between the atomized fluid and the inner wall of the atomization channel. However, providing a circular pipe at the mist outlet will greatly increase the flow resistance. The rhombus or shuttle shape can reduce the flow resistance and increase the working efficiency of the large fan.

[0015] Furthermore, the atomization channel is provided with a mist outlet section, which is arranged in front of the large axial flow fan. The mist outlet section extends along an inverted U-shaped trajectory and is provided with multiple mist outlets, so that the atomized fluid can be diffused into the airflow more evenly to avoid concentrated diffusion in one area.

[0016] Furthermore, the atomization channel is provided with a mist outlet section, which is arranged in front of the large axial flow fan. The mist outlet section is extended along an O-shaped trajectory. The atomization channel and the mist outlet section form a ρ-shaped structure. The mist outlet section is provided with multiple mist outlets, which can achieve a more uniform mist outlet effect and is also easier to set up a liquid return channel.

[0017] Furthermore, a liquid return pipe is provided outside the atomization channel and is connected to the atomization chamber. Water droplets are easily condensed at some bending positions, so a liquid return pipe is provided to ensure liquid reflux. The liquid return pipe has a smaller space to form a larger positive pressure to achieve a better air flow effect.

[0018] Furthermore, an air filter is provided outside the atomization channel, which can filter dust and other foreign matter in the air. The filter can also absorb water droplets that condense on the atomization channel and flow down, and then diffuse into the air by evaporation, thereby increasing the humidity of the air.

[0031] As required, detailed embodiments of the present invention are disclosed herein, but it should be understood that the disclosed embodiments are merely exemplary of the present invention, and the present invention may be implemented in different and alternative forms. The accompanying drawings may not be drawn to scale, and certain features may be exaggerated or reduced to show the details of specific components. Therefore, the specific structural and functional details disclosed herein should not be understood as having a limiting meaning, but only as a representative basis to teach those skilled in the art to adopt the present invention differently. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a humidifier, specifically an ultrasonic humidifier, includes an atomizing chamber 1 and an atomizing channel 2, the atomizing channel 2 is arranged above the atomizing chamber 1, the atomizing chamber 1 and the atomizing channel 2 are evenly distributed or surrounded by an air flow channel 3, the air flow channel 3 is provided with an air inlet 31 and an air outlet 32, the air inlet 31 is located outside the atomizing chamber 1 and the atomizing channel 2, the air outlet 32 ​​is located inside the atomizing chamber 1 or the atomizing channel 2, the opening of the air outlet 32 ​​is tilted upward or vertically upward and parallel or nearly parallel to the axial direction of the atomizing channel 2, the larger the angle between the opening direction of the air outlet 32 ​​and the axial direction of the atomizing channel 2, the easier it is to generate turbulence, once turbulence is generated, the atomized fluid 12 in the atomizing channel 2 is easy to contact the inner wall of the atomizing channel 2, condense on the inner wall of the atomizing channel 2 to produce water droplets, and reduce the atomization efficiency. The opening of the air outlet 32 ​​determines the direction of the airflow, so in order to reduce turbulence, parallel airflow is the best choice.

[0033] like Figure 1 and Figure 2 As shown, in order to meet the needs of different environments and locations, the humidifier is provided with a battery compartment 4, which can be powered by batteries. This has certain requirements on the working efficiency of the humidifier. The higher the working efficiency of the humidifier with the same power, the longer the battery life. The atomization chamber 1 is set in the first water tank 13, and the first water tank 13 is connected to the second water tank 14 through a control valve. When the water level of the first water tank 13 is lower than a certain height, the second water tank 14 can replenish the water for the first water tank 13. Considering the situation of external power supply, an independent power supply compartment 5 can be set in the humidifier to adjust the power supply voltage to charge the battery or directly drive the humidifier to work. A control panel 6 can also be set on the humidifier to realize the control of various functions of the humidifier. A roller 7 can be set at the bottom of the humidifier to facilitate the movement of the humidifier.

[0034] like Figure 3 and Figure 7As shown, the atomization channel 2 is provided with a plurality of air inlets 31, and the direction of the air inlets 31 is parallel to the axial direction of the atomization channel 2, and is in a vertically upward direction. Of course, after entering the atomization channel 2, some air may also flow upward at an angle, and will mix with the atomized fluid 12, which is also inevitable. Therefore, it is necessary to set another air inlet 31 after a certain distance to ensure the isolation effect of other positions, so as to maximize the atomization effect and reduce the proportion of condensation after atomization.

[0035] like Figure 7 As shown, an air filter 8 is provided outside the atomizing channel 2, and the air filter 8 wraps the entire atomizing channel 2. The air filter 8 absorbs the water droplets condensed in the atomizing channel 2 and uses the airflow to allow the water droplets to evaporate slowly. As a preferred solution, the bottom of the air filter 8 is located in the first water tank 13 so that the excess water that is not evaporated in time by the air filter 8 can enter the first water tank 13 for recycling. Generally speaking, this situation will not occur in an environment with low humidity, but in an extreme environment with high humidity and low temperature, if the humidifier starts working, the air filter 8 may be relatively wet, that is, the air filter 8 may produce dripping in an extreme environment, so it can be prevented.

[0036] Embodiment 1:

[0037] like Figure 2 , Figure 3 and Figure 7 As shown, an annular air channel 33 is provided in the circumferential direction of the atomizing chamber 1 and the atomizing channel 2, and the air outlet 32 ​​of the annular air channel 33 is arranged along the inner wall of the atomizing chamber 1 or the atomizing channel 2. An atomizing tube 15 is provided in the circumferential direction of the atomizing chamber 1, and a water inlet hole 16 is provided in the side wall of the atomizing tube 15. The water inlet hole 16 is connected with the first water tank 13 so that the water in the first water tank 13 enters the atomizing chamber 1 through the water inlet hole 16. A piezoelectric ceramic sheet 17 is provided at the bottom of the atomizing chamber 1 to generate ultrasonic vibration under the action of a power supply of a certain frequency, so that a large amount of atomized fluid 12 can be generated in the atomizing chamber 1 under the action of the piezoelectric ceramic sheet 17, and is thrown out of the atomizing tube 15 under the action of inertia. A first conduit 18 is provided outside the atomizing tube 15, and the first conduit The inner diameter of 18 is larger than the outer diameter of the atomizing tube 15, and an annular air passage 33 is formed at the transition position between the first conduit 18 and the atomizing tube 15, that is, the positive pressure air generated outside the first conduit 18 and the atomizing tube 15 can enter the first conduit 18 through the gap between the first conduit 18 and the atomizing tube 15, and this part of the air will move along the inside of the first conduit 18 under the action of inertia, so the atomized fluid 12 in the first conduit 18 can be separated from the inner wall of the first conduit 18, thereby reducing the chance of the atomized fluid 12 contacting the first conduit 18.

[0038] like Figure 2 , Figure 3 and Figure 7As shown, the first conduit 18 is configured as a conical conduit, that is, the radius of the lower end is greater than the radius of the upper end, and a second conduit 19 is arranged above the first conduit 18. The second conduit 19 is also configured as a conical conduit, that is, the radius of the lower end is greater than the radius of the upper end. Of course, if there is enough space, the larger the conduit radius, the better, and it does not need to be configured as a cone. In addition, under special circumstances, the conduit can also be designed to be curved, but the atomization efficiency of the curved shape will decrease relative to the straight structure. However, compared with other solutions in the prior art, the atomization efficiency of the annular airway 33 is still increased to a certain extent, so it also has obvious advantages. Therefore, the technical solution of the present application does not specifically limit the shape of the conduit, and it can be designed according to actual needs. Figure 7 This is an implementation method of a curved duct. This curved design generally requires more air to be introduced on the outer side of the curve to achieve a better protection effect. Wrapping the air filter 8 on the outside of the duct is also a better choice. A small fan 10 can be used to form an air positive pressure zone outside the duct. A humidifier shell can be used to form it. A return pipe 81 can also be separately set outside the duct. In this way, the air outside the duct has a tendency to flow into the duct, forming a stable air flow.

[0039] like Figure 2 , Figure 3 and Figure 4 As shown, the air inlet 31 is connected to the chamber 40 in which the small fan 10 is provided, and the small fan 10 can generate a positive pressure airflow. In order to prevent liquid from entering the chamber of the small fan 10, a fan cover 20 is provided above the small fan 10, and an air outlet 21 is provided at the position of the fan cover 20 facing away from the atomizing chamber 1, so that the small fan 10 can be protected and prevented from getting wet. Positive pressure is relative to atmospheric pressure. Pressure greater than atmospheric pressure is positive pressure, and pressure less than atmospheric pressure is negative pressure.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, the mist outlet 22 of the atomizing channel 2 is provided with a large fan 9 so that the rotation of the large fan 9 accelerates the gas flow and can reduce the pressure of the atomizing channel 2 to form a negative pressure. The greater the air flow rate, the smaller the static pressure, so the static pressure of the mist outlet 22 will decrease when the large fan 9 is started, and the faster the wind speed of the large fan 9, the smaller the static pressure of the mist outlet 22. If the large fan 9 is large enough, the small fan 10 can be turned off, or the humidifier is not directly provided with a small fan 10, and an air inlet can be provided at a suitable position.

[0041] like Figure 2 , Figure 3 and Figure 7As shown, the atomization channel 2 includes a delivery channel and a diffusion channel, and the cross-sectional shape transitions from the circular shape of the delivery channel to the approximately rhombus or shuttle shape of the diffusion channel. The circular structure has certain advantages in conveying fluids, but at the mist outlet 22, the circular structure will produce a large flow resistance, affecting the working efficiency of the large fan 9, so the mist outlet 22 needs to be optimized and improved.

[0042] like Figure 5 , Figure 6 and Figure 7 As shown, the atomizing channel 2 is provided with a mist outlet section 26, the cross section of which is diamond-shaped. The mist outlet section 26 is arranged in front of the large axial flow fan 9, and the mist outlet section 26 extends along an inverted U-shaped trajectory. The mist outlet section 26 is provided with a plurality of mist outlets 22. The mist outlets 22 include an annular mist outlet 23, a hole-shaped mist outlet 24, and a top mist outlet 25. The top mist outlet 25 facilitates the atomized fluid 12 with a larger density to leave the atomizing channel 2 directly from the top, and the hole-shaped mist outlet 24 facilitates the atomized particles with a smaller particle size to quickly enter the air duct formed by the large fan 9 by utilizing the pressure difference to fully mix with the air. The annular mist outlet 23 extends along the entire mist outlet section 26, and the pressure difference formed by the large fan 9 can be utilized to promote the flow of the atomized fluid 12. The U-shaped structure takes into account the inertial effect of the atomized fluid 12 during the flow, and is also arranged in combination with the action range of the large fan 9 on the other hand. As the mist outlet section 26 extends, the amount of atomized fluid 12 decreases, and the size of the mist outlet section 26 can also be gradually reduced. As shown in FIG. Fig.10 As shown, a liquid return pipe 81 is provided outside the atomizing channel 2, and the liquid return pipe 81 is connected to the atomizing chamber 1. Of course, if an air filter 8 is provided outside the atomizing channel 2, it is generally unnecessary to provide a separate liquid return pipe 81, and the liquid return pipe 81 also has certain advantages, that is, the liquid return pipe 81 is connected to the chamber 40 of the small fan 10 to maintain the positive pressure in the liquid return pipe 81, so that the flow efficiency of the atomized fluid 12 in the atomizing channel 2 is higher.

[0043] like Figure 5 , Figure 6 and Figure 2 As shown, the atomizing channel 2 is provided with a mist outlet section 26, which is arranged in front of the large axial flow fan 9, and the mist outlet section 26 is extended along an o-shaped track, and the atomizing channel 2 and the mist outlet section 26 form a p-shaped structure, and the mist outlet section 26 is provided with a plurality of mist outlets 22. In this way, a closed annular structure is formed, and even if a large number of water droplets are condensed, they can flow into the first water tank 13 along the atomizing channel 2, or directly evaporate into the air using the air filter 8.

[0044] Embodiment 2:

[0045] like Figure 8 , Fig. 9 and Fig.10As shown, 12 air inlet pipes 35 are evenly distributed in the circumferential direction of the atomizing chamber 1 and the atomizing channel 2, and the air outlets 32 of the air inlet pipes 35 are evenly distributed in a ring shape and close to the inner wall of the atomizing chamber 1 or the atomizing channel 2. The atomizing pipe 15 is provided in the atomizing chamber 1, and the atomizing pipe 15 is located in the first water tank 13. A plurality of rectangular holes 34 are evenly distributed in the circumferential direction of the atomizing pipe 15. Water from the first water tank 13 enters the atomizing chamber 1 through the rectangular holes 34, and the air inlet pipe 35 is provided in the rectangular holes 34. As a preferred atomizing chamber 1, the air inlet pipe 35 can be designed as an S-shaped pipe, and a drainage groove 36 is provided at the lower end of the S-shaped pipe. It can also be designed as a straight pipe, but if it is designed outside the atomizing chamber 1, the space is relatively limited, and the straight pipe can penetrate from the bottom of the atomizing chamber 1 to reach the atomizing chamber 1. The structure is simple and the flow resistance is small. The small fan 10 can be arranged below the atomizing chamber 1. The small fan 10 delivers positive pressure air to the atomizing channel 2 and the atomizing chamber 1 through the air inlet 31 of the air inlet pipe 35. The positive pressure air can be used to isolate the atomized fluid 12 from the inner wall of the atomizing channel 2, thereby improving the atomization efficiency. The small fan 10 can also deliver air to the first water tank 13, and deliver the air to the atomizing chamber 1 through the rectangular hole 34. The atomizing channel 2 is arranged in multiple sections in a stepped shape. The air inlet pipe 35 of the atomizing channel 2 can be directly arranged in a straight line. The other structures of the humidifier refer to Example 1, and the same design can be adopted.

[0046] Embodiment 3:

[0047] like Fig.12 As shown, an atomizing tube 15 is provided outside the atomizing chamber 1, a guide ring 37 is provided inside the atomizing tube 15, a pressure-stabilizing hole 38 is provided on the side wall of the guide ring 37, a drainage groove 36 is provided at the bottom of the guide ring 37, and a plurality of air inlets 31 are provided at the position of the guide ring 37 of the atomizing tube 15. In order to prevent the shaking water droplets from entering the air inlet 31 from the guide ring 37 and overflowing to the outside of the atomizing tube 15 during atomization, a reflux ring 39 is provided outside the atomizing tube 15. The direction of the arrow 82 at the center position is the axial direction of the atomizing channel 2. The atomizing channel 2 is provided with multiple levels of atomizing ducts, such as a first duct 18 and a second duct 19. The arrow indicates the flow direction of the flowing air 11. The small fan 10 generates positive pressure air, and the contact between the atomized fluid 12 and the inner walls of the first duct 18 and the second duct 19 is reduced by the action of the flowing air 11, which is different from the prior art. Fig.11 It forms a sharp contrast.
