[0038] Please refer to Figures 1 to 10 , this embodiment provides an industrial humidifier 100, which includes: a box body 1, an atomizing head assembly 2 disposed in the box body 1, a bracket 4 connected to the inside of the box body 1, and a fan 3 connected to the bracket 4. A liquid cavity 10 is provided inside the box body 1, and an automatic water inlet valve 5 is further provided on the box body 1. The automatic water inlet valve 5 is used to automatically control the switch to input water, the liquid to be atomized, into the water tank 1. A potentiometer 6 and a start-stop switch 7 are also embedded on the outer shell of the box body 1. A control box 8 for controlling the operation of the atomizing head assembly 2 is further provided in the water tank 1. The potentiometer 6 is also electrically connected to the control box 8 and is used to input a control signal to control the working power of the atomizing head assembly 2, thereby controlling the amount of mist output. The atomizing head assembly 2 is used to generate ultrasonic vibrations to atomize the atomizing liquid in the liquid cavity 10. The start-stop switch 7 is also electrically connected to the control box 8 and is used to control the opening or closing of the fan 3 and the atomizing head assembly 2. The fan 3 is used to inhale the air in the external environment of the box body 1 and convey it to the position where the atomizing head assembly 2 is located, so as to accelerate the output of the water mist atomized by the atomizing head assembly 2.

[0039] The internal cavity of the water tank 1 is separated by the bracket 4 into two communicating cavities. One of them is the above-mentioned liquid cavity 10, and the other cavity 40 is used to arrange the bracket 4, the control box 8, the automatic water inlet valve 5, etc.

[0040] Please refer to Figures 5 to 7 , the atomizing head assembly 2 includes a plurality of atomizing heads 21 arranged in parallel. The plurality of atomizing heads 21 are respectively and independently controlled by the control box 8 to work, that is, the working states of each atomizing head 21 do not affect each other and are independently controlled by the control box 8. A mounting plate 111 is provided at the bottom of the box body 1, and the plurality of atomizing heads 21 are all fixedly connected to the mounting plate 111. In this embodiment, the plurality of atomizing heads 21 are arranged in a matrix on the mounting plate 111. The mounting plate 111 is provided with mounting holes corresponding to the atomizing heads 21. The atomizing surface of the atomizing sheet on the atomizing head 21 extends into the liquid cavity 10 through the mounting holes, so that the atomizing sheet can be in full contact with the atomizing liquid. The atomizing head 21 is fixedly connected to the mounting plate 111 by screws.

[0041] In this embodiment, several atomizing heads 21 are respectively and independently electrically connected to the control box 8, and the working state of each atomizing head 21 is independently controlled by the control box 8. Therefore, the failure of an individual atomizing head 21 does not affect the working state of other atomizing heads 21, so that the industrial humidifier can continue to work. At the same time, with the design of independently parallel-connected atomizing heads 21, the later maintenance and replacement of the atomizing heads 21 are more convenient and fast. Only the faulty atomizing head 21 needs to be replaced correspondingly, without the need to replace the entire atomizing head assembly 2, thus saving costs.

[0042] In this embodiment, the atomizing head assembly 2 is fixedly arranged at the bottom of the liquid chamber 10. In other embodiments, a float or floating body can also be used to suspend the atomizing head assembly 2 in the atomizing liquid, so that the atomizing head assembly 2 can rise and fall synchronously with the liquid level of the atomizing liquid, improving the fog output and enhancing the atomizing efficiency.

[0043] Among them, the control box 8 includes a control circuit board and a sealed box body for placing the control circuit board. The control circuit board is externally connected to an external power supply or an internal energy storage power supply, and receives the control signals of the potentiometer 6 and the start-stop switch 7, and synchronously controls the working modes and states of the fan 3 and the atomizing head assembly 2.

[0044] Please refer to again Figures 5 to 8 , the atomizing head assembly 2 is arranged at the right bottom inside the box body 1, the bracket 4 is arranged above the left side inside the box body 1, and the corresponding fan 3 is arranged on the bracket 4. An air inlet channel communicating with the bottom of the box body 1 is arranged inside the bracket 4, or the bracket 4 and the side wall and bottom of the box body 1 jointly enclose an air inlet channel. The air inlets of the air inlet channel or the air inlet channel are all arranged at the bottom of the box body 1 so as to input air from the bottom of the box body 1. Correspondingly, an air outlet 41 is arranged on the bracket 4, and the air outlet 41 is arranged opposite to the air inlet end of the fan 3, and the air outlet of the fan 3 faces the atomizing head assembly 2.

[0045] Specifically, the air inlet opened at the bottom of the box body 1 is arranged below the atomizing head assembly 2, and no air inlet is arranged in other parts of the bottom of the box body 1. At the same time, the bottom end of the atomizing head assembly 2 is exposed to the space above the air inlet. Since heat will be generated during the operation of the atomizing head assembly 2, these heats will affect its working efficiency, so it is necessary to discharge them in time. The air inlet of the input gas passage of the fan 3 is opened at a position below the atomizing head assembly 2, so that air flows through the bottom space 110 of the atomizing head assembly 2, thereby taking away the heat generated when the atomizing head 21 works, improving the working efficiency and service life of the atomizing head 21. The wire of the atomizing head 21 is led out from its bottom and electrically connected to the control box 8. It should be noted that the air inlet passage connecting the fan 3 only needs to pass through the bottom of the atomizing head 21 to take away the heat generated by the atomizing head 21. As for the air inlet, it can also be arranged at other positions of the box body. At the same time, the fan 3 inhales the gas with a higher temperature, and this gas will also increase the temperature of the aerosol atomized by the atomizing head assembly 2, making it diffuse faster.

[0046] The bracket 4 divides the inner cavity of the box body 1 into two cavities. The automatic water inlet valve 5 is arranged in the cavity 40. The cavity 40 is in a communicating state with the liquid cavity 10, so that the liquid level in the liquid cavity 10 is kept consistent with the liquid level in the cavity 40. The volume of the liquid cavity 10 is larger than the volume of the cavity 40. The liquid cavity 10 is used to store the atomizing liquid, and the cavity 40 is used to arrange the automatic water inlet valve 5. The automatic water inlet valve 5 includes a controllable switch valve and a water level detection unit. The water level detection unit can detect the lower limit water level and the upper limit water level. When the liquid level in the cavity 40 is lower than the lower limit water level, the automatic control switch valve is opened to transport the atomizing liquid to the cavity 40 from the outside; on the contrary, when the liquid level in the cavity 40 is higher than the upper limit water level, the switch valve is automatically closed to block the input of the atomizing liquid from the outside to the cavity 40, so as to keep the liquid level in the cavity 40 within the set height range. Since the liquid cavity 10 is in a communicating state with the cavity 40, the water level detection unit also correspondingly monitors the liquid level height of the liquid cavity 10. Too high a liquid level will cause the liquid to overflow from the box body 1, and too low a liquid level will also cause the atomizing head 21 to be exposed to dry burning and damaged. Therefore, it is necessary to strictly detect the liquid level height of the liquid cavity 10.

[0047] Since the atomizing liquid will fluctuate greatly due to vibration during the operation of the atomizing head assembly 2, the corresponding liquid level will inevitably fluctuate greatly. The water level detection unit of the automatic water inlet valve 5 is used to detect the height value of the liquid level. Therefore, this liquid level fluctuation will cause inaccurate detection of the liquid level value, which may cause the control box to receive incorrect information and send out incorrect control signals, resulting in the atomizing head assembly 2 being in an abnormal working state, and even causing the atomizing head assembly 2 to be damaged and scrapped. Therefore, the bracket 4 divides the interior of the box body 1 into an independent cavity 40, or the bracket 4 has a partition part, and the partition part and the box body 1 enclose the cavity 40, so as to form a cavity that is connected to the liquid cavity 10 but relatively independent of each other. Due to the isolation and blocking effect of the bracket 4, the fluctuation impact on the liquid level generated by the atomizing head assembly 2 during operation will not be directly transmitted to the liquid level inside the cavity 40, and the water level detection unit located in the cavity 40 is significantly less affected by the liquid level fluctuation, so that the detected liquid level value is more accurate, thus avoiding mis-triggering of the control box 8 and outputting incorrect control signals, and protecting the normal operation of the atomizing head assembly 2.

[0048] Further, please refer to again Figure 4 , a groove 112 is recessed downward at the position below the bracket 4 of the mounting plate 111, the bottom of the water level detection unit of the automatic water inlet valve 5 extends into the groove 112, the atomizing head 21 is connected to the mounting plate 111, and the longitudinal height of the groove 112 is lower than the position where the atomizing head 21 is located. Therefore, the atomizing liquid will preferentially fill the groove 112, and when the groove 112 is filled, it will flow to the liquid cavity 10. Since the water level detection unit of the automatic water inlet valve 5 cannot directly detect the accurate liquid level height above the atomizing head 21, a groove 112 with a lower position is provided on the mounting plate 111, and the water level detection unit is arranged in the groove 112. The lower limit detection height of the water level detection unit is not lower than the horizontal plane height where the atomizing head 21 is located, so as to ensure that when the actually detected liquid level value in the cavity 40 is lower than the lower limit value, the liquid level above the atomizing head 21 is still not lower than the height of the atomizing surface of the atomizing head 21, thus maximizing the guarantee that the atomizing head 21 will not be damaged due to lack of atomizing liquid. When the water is lacking, the water level detection unit will be triggered preferentially and control the automatic water inlet valve to open and input the atomizing liquid.

[0049] In another embodiment, a low liquid level sensor and a high liquid level sensor are further provided in the cavity 40 to assist the liquid level detection of the automatic water inlet valve 5, further improving the accuracy and reliability of the detection.

[0050] The water inlet end of the automatic water inlet valve 5 is externally connected to an external water pipe, and the water outlet end extends into the cavity 40 for inputting atomizing liquid into the cavity 40.

[0051] Specifically, please refer to Figure 11, an air outlet 41, an installation groove 42 for installing and fixing the fan 3, and a partition 43 for separating the interior of the box body 1 into a cavity 40 and a liquid chamber 10 are provided on the bracket 4.

[0052] Please refer to again Figure 1 , Figure 2 and Figure 10 , the box body 1 includes: a box main body 11, a top cover 12 connected to the top surface of the box main body 11, and a bottom plate 13 connected to the bottom of the box main body 11. The middle of the bottom 119 of the box main body 11 is a convex structure. When the box body 1 is placed on a bearing surface, there is a certain height difference between the box body 1 and the bearing surface, so as to prevent the bottom of the box body 1 from directly contacting the bearing surface, and prevent liquids such as water in the external environment from entering the box body 1 and damaging the internal electrical components. The bottom plate 13 is snap-connected or screwed to the convex part of the bottom 119 of the box body 1.

[0053] As Figure 14 shown, a plurality of air inlets 131 are provided on the bottom plate 13, and the air inlets 131 are only opened directly below the atomizing head assembly 2, so that when external air enters the box body 1, the heat generated by the work of the atomizing head 21 is taken away together.

[0054] As Figure 13 shown, a mist outlet 121 is further provided on the top cover 12, and a movable buckle 122 is provided on the side edge of the opposite side of the top cover 12. A clamping convex is provided on the top surface edge of the corresponding box main body 11. When the top cover 12 is closed on the box main body 11, rotating the movable buckle 122 can lock the top cover 12 on the box main body 11. Adopting a movable buckle 122 and other snap connection methods can improve the assembly efficiency and facilitate quick opening of the box body 1 for maintenance in the later stage. It can be understood that in other embodiments, the top cover 12 can also adopt other structural designs of snap connection with the box main body 11, or can adopt screw connection.

[0055] An inlet 18, an overflow port 16 and a drain port 17 for connecting an automatic water inlet valve 5 are further provided on the side wall of the box main body 11. The longitudinal height of the drain port 17 is lower than that of the overflow port 16, and the longitudinal height of the overflow port 16 is lower than that of the inlet 18. A rubber plug is provided on the drain port 17. A plurality of reinforcing ribs are further provided on the side wall of the box main body 11 to improve the overall strength of the box body 1.

[0056] The side wall of the box body 11 is also provided with a side mist outlet, and the top cover 12 is provided with a mist outlet 121. The side mist outlet and the mist outlet 121 are respectively connected with a mist outlet pipe 15 or a cover plate 14. When the mist outlet 121 is opened, mist can be discharged upward from the top of the box body 1, and when the side mist outlet is opened, mist can be discharged from the side wall of the box body 1, thereby adapting to the requirements of the mist outlet direction in different environments. Obviously, the cover plate 14 and the mist outlet pipe 15 can be interchanged on the side mist outlet and the mist outlet 121 according to actual needs, and the cover plate 14 can seal the mist outlet that does not need to be opened.

[0057] Please refer again Figure 11 and Figure 12 , the bracket 4 is also provided with a snap guide rail 431, and the corresponding inner side wall of the box body 1 is also provided with a snap guide groove 1101, and the bracket 4 is fixedly connected by sliding the snap guide rail 431 with the snap guide groove 1101. Specifically, the snap guide rail 431 includes two longitudinally arranged L-shaped snap-in parts, and the snap guide groove 1101 is two linear snap-in grooves corresponding to the L-shaped snap-in parts, and the L-shaped snap-in parts are slidably inserted into the linear snap-in grooves from top to bottom. Among them, the overflow port 16 is provided in the middle of the snap guide groove 1101, that is, the overflow port 16 is located between the two linear snap-in grooves. When the bracket 4 is assembled in the box body 1, the bracket 4 will block the overflow port 16, but a certain gap will be reserved. When the water level in the cavity 40 is higher than the overflow port 16, the water will be discharged from the overflow port 16 to prevent the liquid level from exceeding the upper limit value. The advantage of the structural design of using the bracket 4 to shield the overflow port 16 is that the traditional overflow function is retained while preventing the water mist generated in the liquid chamber 10 from being discharged from the overflow port 16. The shielding structure can prevent the atomized water mist from being output from the overflow port 16.

[0058] The industrial atomizer 100 of this embodiment is designed to be controlled independently in parallel by designing the atomizing assembly 2 as a plurality of atomizing heads 21, which can be easily repaired or replaced separately in the later stage. The air inlet is arranged below the atomizing head 21, so that the heat generated at the atomizing head 21 is taken away while the fan 3 delivers air to the liquid cavity, thereby improving the working efficiency and service life of the atomizing head 21. The cavity 40 and the liquid cavity 10 that are connected are isolated in the box 1 by the bracket 4, and the automatic water inlet valve 5 is arranged in the cavity 40, so as to avoid the influence of the liquid level fluctuation caused by the vibration generated by the operation of the atomizing head assembly 2 on the water level detection unit. A groove 112 is further arranged at the bottom of the cavity 40, and the water level detection unit is sunk into the groove 112, so as to improve the accuracy of liquid level detection. In addition, the top cover 12 of the box 1 is connected by a movable buckle, which has high assembly efficiency and is convenient for subsequent unpacking and maintenance. The position design of the bracket 4 and the overflow port 16 prevents water mist from being discharged from the overflow port 16 while retaining the traditional overflow port.

[0059] The industrial humidifier 100 of this embodiment can be used for dust removal and purification, and can also be used in scenarios such as air curtain cabinets and landscape creation.

[0060] The above only uses embodiments to further illustrate the technical content of the present invention, so as to make it easier for readers to understand, but it does not mean that the implementation manners of the present invention are limited to this. Any technical extension or re-creation based on the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
