For the sake of clarity of the present invention, the front side, the rear side, the left side, the right side, the upper side and the lower side as shown in fig. 2 are also defined. As shown in fig. 1 to 5, in a first plane 102 perpendicular to the rotation axis of the motor 112b, the projection of the housing 12 in the first plane 102 in the direction of the rotation axis is substantially rectangular. Wherein the gantry 12 comprises an extension that can be placed and extends in a plane parallel to the placement plane 101 of the external environment. The moving wheel is arranged within the extension, in particular at one end of the extension. Frame 12 partially surrounds the peripheral sides of fan assembly 112 and is connected thereto by at least a first pivot point 127, and further, frame 12 includes a second pivot point 128. The fan assembly 112 can rotate around the pivot to drive the water mist sprayed from the nozzle to cover a wider range.

The frame 12 includes a first linkage assembly 121, a second linkage assembly 122, and a third linkage assembly 123. The second connecting assembly 122 is fixedly connected to the first connecting assembly 121 and the third connecting assembly 123, respectively. In fact, the first connecting member 121, the second connecting member 122 and the third connecting member 123 may be integrally formed as long as the three structurally satisfy the strength requirement. The housing 12 is formed with a receiving slot for receiving the host 11, and the host 11 is at least partially disposed in the receiving slot and is fixedly connected or detachably connected to the housing 12. In the present embodiment, a first buffer portion 124 is disposed at the connection position of the second connection assembly 122 and the first connection assembly 121, and the first buffer portion 124 intersects with the first connection assembly 121 and the second connection assembly 122 in an inclined manner; the second buffer part 125 is arranged at the joint of the second connecting assembly 122 and the third connecting assembly 123, and the second buffer part 125, the second connecting assembly 122 and the third connecting assembly 123 are simultaneously obliquely intersected, so that the switching of the spray fan in different standing postures is more convenient when the size of the whole machine is saved. In this embodiment, the first connecting assembly 121, the second connecting assembly 122 and the third connecting assembly 123 also extend in respective planes, thereby forming a plane on which the spray fan 100 can be placed. That is, the first connecting assembly 121, the second connecting assembly 122 and the third connecting assembly 123 can be used as extensions and can be used for placing the spray fan 100.

Specifically, the first buffer 124 and the second buffer 125 are shell-shaped with a plurality of contact surfaces, and the first connecting assembly 121, the second connecting assembly 122, and the third connecting assembly 123 include a plurality of connecting rods arranged at intervals, and the connecting rods are connected to the above buffers. The atomizing fan 100 includes at least a first standing posture and a second standing posture, and different positions of the housing are in contact with the placement plane 101 and provide support when the atomizing fan is in different standing postures, and the standing posture means that the fan can be stably supported on the placement plane 101 without depending on an external force, and does not exclude a case where the atomizing fan moves along the placement plane 101 in the standing posture. In this embodiment, partial end surfaces of the first and second buffer portions may be used as a placing surface for the spray fan 100, and a plane on which the end surfaces are located is tangent to the lower edge of the movable wheel 14, and the second connecting component 122 is located above or flush with the plane, so that the fan can stand stably in the first standing posture shown in fig. 2. The second standing position is provided, for example, when the first connecting assembly 121 is used as the bottom side, the other end of the first connecting assembly 121 is provided with a shell-shaped end portion, the lower edge of the moving wheel 14 and one end of the first buffer portion 124 are used as a standing support, that is, an extension portion is formed, and the first connecting assembly 122 is located above or flush with the plane, so that the stable standing of the spray fan can be ensured.

As shown in fig. 1, 2, and 6, the second buffer 125 is further provided with a battery compartment 126 for connecting the power module 13. As one implementation, the power supply component 13 is provided as one or more battery packs that may be mounted directly to the battery compartment 126. The first connecting assembly 121, the second connecting assembly 122 and the third connecting assembly 123 each comprise a set of substantially parallel connecting rods. Wherein the battery compartment 126 is substantially arranged in the seam of the substantially parallel arranged connecting rods of the third connecting assembly 123. And makes full use of the space between the third connecting member 123 and the main body 11. Here, the battery compartment 126 also substantially utilizes the space of the joint of the connection rod of the third connection member 123. The battery compartment 126 is substantially rectangular in shape, hollow inside, and can be engaged with the power module 13. A coupling portion or a connection terminal (not shown) for connecting a battery pack is further provided in the battery housing 126 so that the battery pack can be electrically connected to the control circuit when the battery pack is inserted into the battery housing 126. In this embodiment, the battery compartment 126 is further provided with a compartment cover 126a, and the compartment cover 126a can rotate around a rotating shaft and has a first position for closing the space in the battery compartment 126 and a second position for opening the space in the battery compartment 126. It will be appreciated that the compartment cover 126a is disposed on the battery compartment 126 at an end remote from the third connection assembly 123, thereby avoiding interference with the third connection assembly 123 when the compartment cover 126a is transitioned between the first and second positions. The battery compartment 126 also extends along the extending direction of the second buffer portion 125, so as to better fit with the connecting rod of the third connecting component 123, so that the connection relationship between the battery compartment 126 and the third connecting component 123 is tighter. In fact, the battery compartment 126 is disposed near the second connecting assembly 122, so that after the battery compartment 126 is installed with the battery, the center of gravity of the whole spray fan 100 is closer to the lower side, thereby making the spray fan 100 more stable when being placed and less prone to lodging under the impact of the external environment. The second connecting member 122 extends substantially in a plane perpendicular to the up-down direction, and the outer contour of the battery compartment 126 is disposed above the plane, that is, when the spray fan 100 is normally placed, the outer contour of the battery compartment 126 does not interfere with the second connecting member 122, and the lower surface of the second connecting member 122 is used as a contact surface. In the present embodiment, an acute angle α between the extending direction of the battery compartment 126 and the placing plane 101 is set to be equal to or greater than 0 ° and equal to or less than 90 °, preferably equal to or greater than 10 ° and equal to or less than 75 °, so as to match the shape of the second buffer 125.

In the present embodiment, since the rated power of the atomizing fan 100 is large, in order to satisfy the functional output of the atomizing fan 100 for a long time, the power supply module 13 is set to have a large capacity, so that it has a large weight. In addition, the main body 11 occupies a large space in the up-down direction and the left-right direction because it is necessary to satisfy a large area of blowing or spraying. Specifically, the size of the main body 11 in the vertical direction is 400mm or more and 550mm or less; the dimension of the main body 11 in the left-right direction is 400mm or more and 500mm or less. When the main unit 11 is mounted on the chassis 12, the overall diameter of the spray fan 100 is equal to or greater than 550mm and equal to or less than 1000mm, specifically, the size of the entire spray fan 100 in the vertical direction is set to be equal to or greater than 600mm and equal to or less than 750mm, and the size of the entire spray fan 100 in the horizontal direction is set to be equal to or greater than 650mm and equal to or less than 800 mm. In the present embodiment, the main body 11 of the atomizing fan 100 is further provided with a handle portion 111e for carrying, and the handle portion 111e occupies a preset height in the vertical direction, so that the size of the entire atomizing fan 100 in the vertical direction is greater than or equal to 620mm and less than or equal to 720 mm. Through the arrangement, the air volume blown out by the spray fan 100 provided by the embodiment can reach 5000cfm, so that a better cooling effect is realized.

As shown in fig. 9, the atomizing fan 100 is further provided with a movable wheel 14 as one implementation. Specifically, the moving wheel 14 is provided at the first buffer portion 124 and is rotatable about a rotation axis. Specifically, the rotation shaft is provided on the first connection assembly 121 or the second connection assembly 122. As one implementation, two moving wheels 14 are provided, which are respectively located on the connecting rods of the first connecting assembly 121 or the second connecting assembly 122. It will be appreciated that one or more moving wheels 14 may be provided so as to be selectively provided on the connecting rod and movable by the atomizing fan 100. The moving wheel 14 has a circumferential outer contour, which is substantially flush with the placing plane 101 or located above the placing plane 101 when it is mounted to the first connecting assembly 121 or the second connecting assembly 122, so that when the atomizing fan 100 is placed normally, the outer contour of the moving wheel 14 does not interfere with the second connecting assembly 122, and the lower surface of the second connecting assembly 122 is used as a contact surface, or the outer contour of the moving wheel 14 and the lower surface of the second connecting assembly 122 are simultaneously used as contact surfaces. To facilitate movement of the spray fan 100, a handle assembly 15 is also provided which cooperates with the moving wheel 14. Specifically, the handle assembly 15 includes a main body portion 151 extending substantially in a linear direction and a grip portion 152 connected to the main body portion 151. The grip portion 152 includes an inner profile and an outer profile. Wherein the inner contour is distributed around the battery compartment 126, and the outer contour is disposed to be flush with the placing plane 101 or to be located on the upper side of the placing plane 101 in the up-down direction. The grip portion 152 includes a first grip portion 152a extending in the same direction as the battery compartment 126 and a second grip portion 152b substantially parallel to the placement plane 101. The first grip portion 152a includes two oppositely disposed units, and the second grip portion 152b is configured as a semi-enclosed ring member connecting the two first grip portions 152 a. Because the spray fan 100 of the present embodiment has a plurality of standing postures, the above structure, in combination with the positions of the third connecting assembly 123 and the battery compartment 126, can fully protect the safety of the battery compartment 126 in different standing postures, and even in a walking state of the fan, can also improve the stability of the battery and reduce the vibration of the battery. Based on the size of the spray fan 100 in this embodiment, the arrangement of the battery compartment 126 can make the whole machine have a more stable center of gravity.

The handle assembly 15 is also arranged in a telescoping configuration and on the second connecting assembly 122 at the end remote from the moving wheel 14. In this embodiment, the connecting rod of the second connecting assembly 122 is provided as a hollow structure that can be used to accommodate at least part of the handle assembly 15.

The handle assembly 15 has a first state and a second state. When the handle assembly 15 is in the first state, the handle assembly 15 is in a retracted state, in which the inner contour of the grip portion 152 substantially conforms to or is adjacent to the battery compartment 126. The main body 151, the first grip 152a, and the second grip 152b surround the respective sides of the battery compartment 126. When the handle assembly 15 is in the second state, the handle assembly 15 is in the extended state, and the main body 151 of the handle assembly 15 extends out of the second connecting assembly 122 to a predetermined length, so as to facilitate gripping, and at this time, the spraying fan 100 can be dragged at an angle to the ground and can roll along the ground under the action of the roller. For ease of operation, the centre of gravity of the spray fan 100 when drawn at an angle to the ground is arranged to lie between the grip portion 152 and the moving wheel 14. More specifically, the center of gravity of the atomizing fan 100 is positioned adjacent to the moving wheel 14 when the fan is towed at an angle to the ground.

As shown in fig. 2 and 8, the atomizing fan 100 is further provided with a control module 16 for controlling an output mode and an output power, and the control module 16 is disposed on the third connecting assembly 123 and located between the two connecting rods of the third connecting assembly 123 and at the upper end of the battery compartment 126. Specifically, the panel of the control module 16 includes a power button 161, an air volume display 162, an air volume control button 163, a mist control button 164, a top button 165, and a first indicator light 166. The power control button is used to control the spray fan 100 to be turned on or off, and can control the spray fan 100 to enter a remote control mode in the on state. In addition, the air volume display 162 includes a plurality of gear displays and can reflect the current output air volume in real time. The air volume control button 163 includes a first control button 163a and a second control button 163 b. The first control button 163a is used to decrease the air volume, and the second control button 163b is used to increase the air volume. The mist control button 164 is used to control the opening or closing of the mist. When the mist is turned off, the atomizing fan 100 may be a general fan, and only blows air. When the mist is turned on, the atomizing fan 100 can perform both the atomizing and blowing actions. As an implementation manner, the water mist control button 164 further includes a water mist multi-stage adjusting button 164a, and the water mist multi-stage adjusting button 164a controls the output power or pressure of the water pump through a line, so as to control the water mist to be sprayed out at different sizes or different speeds and displayed on the display screen, thereby meeting different requirements of different application scenes. The top button 165 is used to control the fan direct motor to reach maximum power and output maximum air volume. When top button 165 is pressed, second indicator light 166 lights up or flashes to indicate that the spray fan is at maximum air flow. When the maximum air flow is reached by pressing the second control button 163b a plurality of times, the second indicator light 166 is also lit or blinked accordingly. In other embodiments, the second indicator light 166 may also be used to display the charge level of the battery assembly.

The embodiment further includes a control method of the nozzle, the control module 16 can control the nozzle 113 to reduce the total amount of water discharged from the nozzle 113 in a period of time, and simultaneously ensure that the water discharge pressure of the nozzle 113 is unchanged, that is, when the outlet pressure of a single nozzle is P in T time, the total amount of water discharged from the nozzle is Q, and this process is recorded as the maximum amount of water required under the predetermined outlet pressure of the nozzle; under the action of the control module, when the outlet pressure of a single nozzle is P in the T time, the total water outlet amount of the nozzle is Q ', and Q' < Q. Specifically, the water yield can be reduced to 10-90% of the maximum water yield Q under the action of the control module, namely Q' is more than or equal to 0.1Q and less than or equal to 0.9Q. Furthermore, the water quantity can be reduced to 33 percent and 66 percent of the maximum water yield Q, and the spraying effect and the cooling performance can also be ensured.

The above-mentioned schemes for reducing the flow rate include, but are not limited to, the following schemes:

in one implementation, the control module 16 controls the nozzle 113 to have an interval time t between the nth spray and the (n + 1) th spray, n ≧ 1. The control module realizes pulse water spraying by controlling the start and stop of the water pump, and keeps original outlet pressure when spraying water mist for the nth time and spraying water mist for the (n + 1) th time, so that the required atomization effect can be ensured and the required water amount can be reduced. When the spraying fan is used as a user, continuous water spraying can affect the user to enable the sprayed part of the user to form gathered water stains, and when the pulse water spraying has the required atomization effect, the water on the skin and the surface of clothes of the user and the water on the surface of an operation object are evaporated by combining continuous air blowing at intervals, so that the operation is kept dry and comfortable. In this implementation, the rotation function of the fan assembly may be combined to cover the water mist to a wider range, specifically, when the atomizing fan 100 is in the spraying interval, the control module 16 may control the atomizing fan 100 to rotate for a certain angle, or when the atomizing fan 100 is in the spraying interval, the control module 16 may control the atomizing fan 100 to reduce the rotation speed, that is, the swing speed is fast when spraying and the swing speed is slow after stopping spraying, and so on.

In another implementation, the control module 16 controls a portion of the nozzles 113 to spray water mist, and the remaining nozzles stop spraying water mist. At the same time, the control module 16 calculates to reduce the water supply by reducing the pump operating power, etc., to maintain the nozzle discharge pressure at a predetermined pressure of 60PSI or more and 1000PSI or less, preferably 80PSI or more and 600PSI or less. In this embodiment, the water pipe assembly 114 connected to each nozzle 113 includes a plurality of independently controlled pipelines, or the water pipe assembly 114 is composed of a main water path and a plurality of branches corresponding to each nozzle 113, and a valve controlled by a control module is disposed at a connection position between the branch and the main water path and is used for controlling opening and closing of each branch. Since in this embodiment the nozzles 113 are equally spaced around the circumference of the fan, when the control section of the nozzles is opened and the section of the nozzles is closed, the open nozzles should be spaced apart and evenly distributed around the spray fan.

In another implementation, the control module 16 controls at least a portion of the nozzle 113 outlet diameter to be reduced, or the nozzle 113 diameter is reduced by user manipulation, including but not limited to rotating the spray head, etc. Specifically, a switching mechanism is provided in the nozzle, and the control module 16 or a user can change the diameter of the nozzle 113 through the switching mechanism. At the same time, the control module 16 calculates to reduce the water supply by reducing the pump operating power, etc., to maintain the nozzle discharge pressure at a predetermined pressure of 60PSI or more and 1000PSI or less, preferably 80PSI or more and 600PSI or less.

The present embodiment also includes a method of controlling a pump to protect operation of the pump. When the pump works and when the working current of the pump is detected to be larger than the maximum rated working current, the control module 16 judges that the pump is locked, and the control module 16 controls the pump to stop working.
