[0038] Please refer to Figures 1 to 10 , this embodiment provides an industrial humidifier 100, and the industrial humidifier 100 includes: a box body 1, an atomizing head assembly 2 disposed in the box body 1, a bracket 4 connected inside the box body 1, and a fan 3 connected to the bracket 4. A liquid chamber 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, i.e., 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, and 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 size of the mist output. The atomizing head assembly 2 is used to generate ultrasonic vibrations so as to atomize the atomizing liquid in the liquid chamber 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 suck in 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 which is the above-mentioned liquid chamber 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 separately 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. The bottom of the box body 1 is provided with a mounting plate 111, and the plurality of atomizing heads 21 are 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 for installing the atomizing heads 21. The atomizing surface of the atomizing sheet on the atomizing head 21 extends into the liquid chamber 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, the plurality of atomizing heads 21 are separately 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 individual atomizing heads 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 at the upper left 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 provided 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 to input air from the bottom of the box body 1. Correspondingly, an air outlet 41 is provided 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 is generated during the operation of the atomizing head assembly 2, these heats will affect its working efficiency, so it needs to be discharged 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 from the outside to the cavity 40; 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 generate large fluctuations due to vibration during the operation of the atomizing head assembly 2, the corresponding liquid level will inevitably have large fluctuations. The water level detection unit of the automatic water inlet valve 5 is used to detect the height value of the liquid level. Therefore, such liquid level fluctuations will cause inaccurate detection of the liquid level value, which may cause the control box to receive incorrect information and issue 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 portion, and the partition portion 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 the 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 As shown in the figure, a groove 112 is recessed downward at the position below the bracket 4 on 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 then flow to the liquid cavity 10 after the groove 112 is filled. 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 of the position 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 protection of the atomizing head 21 from being 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, and further improve 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 isolating the interior of the box body 1 into a cavity 40 and a liquid cavity 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, it takes away the heat generated by the work of the atomizing head 21 at the same time.

[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 protrusion 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] Among them, a side fog outlet is further provided on the side wall of the box body 11, and a fog outlet 121 is provided on the top cover 12. A fog outlet pipe 15 or a cover plate 14 is respectively connected to the side fog outlet and the fog outlet 121. When the fog outlet 121 is opened, fog can be emitted upward from the top of the box body 1, and when the side fog outlet is opened, fog can be emitted from the side wall of the box body 1, so as to meet the requirements of the fog emission direction in different environments. Obviously, the cover plate 14 and the fog outlet pipe 15 can be interchanged in position on the side fog outlet and the fog outlet 121 according to actual needs, and the cover plate 14 can seal the fog outlet that does not need to be opened.

[0057] Please refer to again Figure 11 and Figure 12 Also, a buckle guide rail 431 is further provided on the bracket 4, and a corresponding buckle guide groove 1101 is provided on the inner side wall of the box body 1. The bracket 4 is fixedly connected by sliding and clamping the buckle guide rail 431 with the buckle guide groove 1101. Specifically, the buckle guide rail 431 includes two longitudinally arranged L-shaped clamping parts, and the buckle guide groove 1101 is two linear card slots corresponding to the L-shaped clamping parts. The L-shaped clamping parts are slidably inserted into the linear card slots from top to bottom. Among them, an overflow port 16 is provided in the middle of the buckle guide groove 1101, that is, the overflow port 16 is located between the two linear card slots. When the bracket 4 is assembled to 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 drain from the overflow port 16 to prevent the liquid level from exceeding the upper limit value. The advantage of adopting the structural design of using the bracket 4 to block the overflow port 16 is that the traditional overflow function is retained, and at the same time, the water mist generated in the liquid cavity 10 is prevented from being discharged from the overflow port 16, and the blocking structure can block the atomized water mist from being output from the overflow port 16.

[0058] For the industrial atomizer 100 of this embodiment, by designing the atomization assembly 2 as a plurality of atomizing heads 21 independently controlled in parallel, it is convenient for later individual maintenance or replacement. The air inlet is arranged below the atomizing head 21, so as to take away the heat generated at the atomizing head 21 while the fan 3 sends air to the liquid cavity, improving the working efficiency and service life of the atomizing head 21. The bracket 4 is used to isolate the inside of the box body 1 into a connected cavity 40 and a liquid cavity 10, and the automatic water inlet valve 5 is arranged in the cavity 40, so as to avoid the influence of the vibration generated by the operation of the atomizing head assembly 2 on the liquid level fluctuation on the water level detection unit. Further, a groove 112 is provided 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 body 1 is connected by a movable buckle, with high assembly efficiency and convenient for subsequent opening and maintenance. The position design of the bracket 4 and the overflow port 16 retains the traditional overflow port while preventing water mist from being discharged from the overflow port 16.

[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 is only an example to further illustrate the technical content of the present utility model, so as to make it easier for readers to understand, but it does not mean that the implementation mode of the present utility model is limited to this. Any technical extension or re-creation based on the present utility model is protected by the present utility model. The protection scope of the present utility model is subject to the claims.
