[0038] See also Figures 1 to 10 The present embodiment provides an industrial humidifier 100, which includes: a box 1, an atomizing head assembly 2 disposed in the box 1, a bracket 4 connected to the box 1, and a fan 3 connected to the bracket 4. A liquid chamber 10 is provided in the box 1, and an automatic water inlet valve 5 is also provided on the box 1. The automatic water inlet valve 5 is used to automatically control the switch so as to input water into the water tank 1 to wait for the liquid to be atomized. A potentiometer 6 and a start-stop switch 7 are also embedded on the outer shell of the box 1, and a control box 8 for controlling the operation of the atomizing head assembly 2 is also 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 atomizer head assembly 2 is used to generate ultrasonic vibrations to atomize the atomized liquid in the liquid chamber 10. The start-stop switch 7 is also electrically connected to the control box 8 to control the opening or closing of the fan 3 and the atomizer head assembly 2. The fan 3 is used to inhale air from the external environment of the box body 1 and transport it to the location of the atomizer head assembly 2, so as to accelerate the output of the water mist generated by the atomization of the atomizer head assembly 2.

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

[0040] See also Figures 5 to 7 , the atomizer head assembly 2 includes a plurality of atomizer heads 21 arranged in parallel, and the plurality of atomizer heads 21 are individually controlled by the control box 8 to work, that is, the working states of each atomizer 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 atomizer heads 21 are fixedly connected to the mounting plate 111. In the present embodiment, the plurality of atomizer heads 21 are arranged in a matrix on the mounting plate 111, and the mounting plate 111 is provided with mounting holes corresponding to the installation of the atomizer heads 21, and the atomizing surface of the atomizer sheet on the atomizer head 21 extends from the mounting hole into the liquid chamber 10, so that the atomizer sheet can fully contact with the atomized liquid, and the atomizer head 21 is fixedly connected to the mounting plate 111 by screws.

[0041] In this embodiment, a plurality of atomizer heads 21 are electrically connected to the control box 8 independently, and the working state of each atomizer head 21 is independently controlled by the control box 8. Therefore, failure of an individual atomizer head 21 does not affect the working state of other atomizer heads 21, so that the industrial humidifier can continue to work. At the same time, the design of independent parallel atomizer heads 21 makes it more convenient and quick to maintain and replace the atomizer heads 21 in the later stage. It is only necessary to replace the corresponding atomizer heads 21 that have failed, without having to replace the atomizer head assembly 2 as a whole, thereby saving costs.

[0042] In this embodiment, the atomizer head assembly 2 is fixedly arranged at the bottom of the liquid chamber 10. In other embodiments, a float or a floating body can also be used to suspend the atomizer head assembly 2 in the atomized liquid, so that the atomizer head assembly 2 rises and falls synchronously with the liquid level of the atomized liquid, thereby increasing the mist output and enhancing the atomization 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 connected to an external power supply or an internal energy storage power supply, and receives control signals from the potentiometer 6 and the start-stop switch 7 to synchronously control the working mode and status of the fan 3 and the atomizer head assembly 2.

[0044] Please refer again Figures 5 to 8 , the atomizer head assembly 2 is arranged at the right bottom of the box body 1, the bracket 4 is arranged at the upper left side of the box body 1, and the corresponding fan 3 is arranged on the bracket 4. The bracket 4 is provided with an air inlet channel connected to the bottom of the box body 1, or the bracket 4 and the side wall and bottom of the box body 1 together enclose an air inlet channel, and the air inlet channel or the air inlet of the air inlet channel are both arranged at the bottom of the box body 1, so as to input air from the bottom of the box body 1. Correspondingly, the bracket 4 is provided with an air outlet 41, which is arranged in alignment with the air inlet end of the fan 3, and the air outlet of the fan 3 faces the atomizer head assembly 2.

[0045] Specifically, the air inlet opened at the bottom of the housing 1 is arranged below the atomizing head assembly 2, and no air inlet is arranged at the other parts of the bottom of the housing 1, and the bottom end of the atomizing head assembly 2 is exposed to the space above the air inlet. Since the atomizing head assembly 2 generates heat during operation, the heat will affect its working efficiency, so it needs to be discharged in time. The air inlet of the input gas channel of the fan 3 is opened at the lower position of the atomizing head assembly 2, so that the 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, and 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 channel connected to the fan 3 only needs to pass through the bottom of the atomizing head 21, so as to take away the heat generated by the atomizing head 21, and the air inlet can of course be arranged at other positions of the housing. At the same time, the fan 3 inhales a gas with a higher temperature, which will also increase the temperature of the steam mist atomized by the atomizing head assembly 2, so that it spreads faster.

[0046] The bracket 4 divides the inner cavity of the box body 1 into two cavities, and the automatic water inlet valve 5 is arranged in the cavity 40. The cavity 40 and the liquid cavity 10 are connected so that the liquid level in the liquid cavity 10 is 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 atomized liquid, and the cavity 40 is used to set 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 switch valve is automatically controlled to open to deliver atomized liquid from the outside to the cavity 40; conversely, 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 external input of atomized liquid to the cavity 40, thereby keeping the liquid level in the cavity 40 within the set height range. Since the liquid cavity 10 is in a connected state with the cavity 40, the water level detection unit also monitors the liquid level height of the liquid cavity 10. If the liquid level is too high, the liquid will overflow from the box 1, and if the liquid level is too low, the atomizer head 21 will be exposed to dry burning and damaged, so it is necessary to strictly detect the liquid level height of the liquid cavity 10.

[0047] Since the atomized liquid of the atomizer head assembly 2 will have large fluctuations due to vibration during operation, the corresponding liquid level will inevitably have large fluctuations, and the water level detection unit of the automatic water inlet valve 5 is used to detect the height value of the liquid level, so this liquid level fluctuation will lead to inaccurate detection of the liquid level value, which may cause the control box to receive wrong information and send out wrong control signals, causing the atomizer head assembly 2 to be in an abnormal working state, causing the atomizer head assembly 2 to be damaged and scrapped, etc. Therefore, the bracket 4 isolates 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 are surrounded to form 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 effect of the liquid level generated by the atomizer 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 its detection of the liquid level value is more accurate, thereby avoiding the control box 8 from being triggered by mistake and outputting an erroneous control signal, and protecting the normal operation of the atomizer head assembly 2.

[0048] For further information, please refer again to Figure 4 The mounting plate 111 is located below the bracket 4 and is concavely provided with a groove 112. 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. The longitudinal height of the groove 112 is lower than the position of the atomizing head 21. Therefore, the atomized liquid will first fill the groove 112, and then flow to the liquid chamber 10 when 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 of the water level above the atomizing head 21, a lower groove 112 is set on the mounting plate 111, and the water level detection unit is set 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 atomizing head 21. It can ensure that when the actual 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, thereby maximally ensuring that the atomizing head 21 will not be damaged due to lack of atomized liquid. When there is a lack of water, the water level detection unit will be triggered first and control the automatic water inlet valve to open and input atomized liquid.

[0049] In another embodiment, a low-level liquid level sensor and a high-level liquid level sensor are further disposed in the cavity 40 to assist in liquid level detection of the automatic water inlet valve 5 , thereby further improving the accuracy and reliability of 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 , so as to input atomized liquid into the cavity 40 .

[0051] For details, please refer to Fig.11The bracket 4 is provided with an air outlet 41 , a mounting groove 42 for mounting 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 .

[0052] Please refer again Figure 1 , Figure 2 and Fig.10 The box body 1 comprises: a box body 11, a top cover 12 connected to the top surface of the box body 11, and a bottom plate 13 connected to the bottom of the box body 11. The middle part of the bottom 119 of the box body 11 is an upward 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 avoid the bottom of the box body 1 directly contacting the bearing surface, and to 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-fitted or screwed to the convex part of the bottom 119 of the box body 1.

[0053] like Fig.14 As 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 atomizer head assembly 2 , so that when the external air enters the box body 1 , it also takes away the heat generated by the atomizer head 21 at work.

[0054] like Fig.13 As shown, the top cover 12 is also provided with a mist outlet 121, and a movable buckle 122 arranged on the side opposite to the top cover 12, and the corresponding top edge of the box body 11 is provided with a convex. When the top cover 12 is covered on the box body 11, the top cover 12 can be locked on the box body 11 by rotating the movable buckle 122. The use of the movable buckle 122 and other buckle connection methods such as the convex buckle can improve the assembly efficiency and facilitate the rapid opening of the box body 1 for inspection and maintenance at a later stage. It is understandable that in other embodiments, the top cover 12 can also adopt other buckle-connected structural designs with the box body 11, or can be connected by screws.

[0055] The side wall of the box body 11 is also provided with a water inlet 18 connected to the automatic water inlet valve 5, an overflow port 16 and a drain port 17. The longitudinal height of the drain port 17 is lower than that of the overflow port 16. The longitudinal height of the overflow port 16 is lower than that of the water inlet 18. A rubber plug is provided on the drain port 17. The side wall of the box body 11 is also provided with a plurality of reinforcing ribs 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 Fig.11 and Fig.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 scenes such as air curtain cabinets and landscaping.

[0060] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this.
