[0085] Figure 1 There is shown a spray fan 100 which blows out wind with water mist through the blowing and spraying functions and can cool and humidify a preset site. The spray fan 100 can be applicable to outdoor places such as basketball courts, parks, playgrounds, etc., and the spray fan 100 can also be applicable to indoor places such as shopping malls, factories, warehouses, etc.

[0086] As Figure 1 and Figure 2As shown, the spray fan 100 includes a fan assembly 11, a body 12, a nozzle 13, and a water injection port 14. Among them, the body 12 forms a frame 120 for supporting the fan assembly 11. The body 12 includes a first housing 121a and a second housing 122a. The first housing 121a forms a first accommodation cavity 121b for accommodating water, and the second housing 122a forms a second accommodation cavity 122b. The water injection port 14 is used to inject water into the first accommodation cavity 121b. There is a sealing assembly 141 matching the water injection port 14, so that when the water injection into the water injection port 14 is completed, the water injection port 14 is closed by the sealing assembly 141.

[0087] To illustrate the technical solution of the present application, the front side, rear side, left side, right side, upper side, and lower side as shown in Figure 1 and Figure 2 are also defined. As shown in Figure 1 and Figure 2 the body 12 is a cubic structure. In some embodiments, in the up and down direction, the length L of the body 12 is less than or equal to 600 mm; in the left and right direction, the width W of the body 12 is less than or equal to 400 mm; in the front and back direction, the thickness T of the body 12 is less than or equal to 200 mm. By setting the body 12 as a regular-shaped structure, the spray fan 100 is more easily stored when being stored.

[0088] As shown in Figure 3 the fan assembly 11 includes a fan blade 111 and a first motor 112 for driving the fan blade 111 to rotate. The first motor 112 is used to drive the fan blade 111 to rotate around the axis of the first motor 112. The first motor 112 is sealed by a waterproof material to prevent water mist from entering the first motor 112 under the action of the environment, etc. For example, the waterproof material can be a plastic film, etc., and the first motor 112 is sealed through a process such as hot air through the plastic film.

[0089] The nozzle 13 is used to spray water mist. The nozzle 13 is arranged on the fan assembly 11 or on the body 12. When the spray fan 100 is started, the water mist is sprayed from the nozzle 13 into the external environment, and the fan blade 111 rotates to generate an air flow to disperse the water mist sprayed from the nozzle 13 into the air, so that the temperature of the air in the environment drops.

[0090] As shown in Figure 4 the spray fan 100 further includes a pump assembly 15. The pump assembly 15 is located in the second accommodation cavity 122b. The pump assembly 15 is used to pump the water in the first accommodation cavity 121b to the nozzle 13.

[0091] As shown in Figure 4As shown, the spray fan 100 further includes a water inlet pipe 151 and a water outlet pipe 152. One end of the water inlet pipe 151 is connected to the first accommodation cavity 121b, and the other end of the water inlet pipe 151 is connected to the pump assembly 15, so that the water inlet pipe 151 can obtain water from the first accommodation cavity 121b and transmit the obtained water to the pump assembly 15, and the pump assembly 15 receives the water obtained from the first accommodation cavity 121b. One end of the water outlet pipe 152 is connected to the pump assembly 15, and the other end of the water outlet pipe 152 is connected to the nozzle 13, and the water is transmitted from the pump assembly 15 to the nozzle 13, so that the nozzle 13 can obtain water for spraying. Among them, the pump assembly 15 can be horizontally arranged in the second accommodation cavity 122b along the left-right direction as shown in Figure 4 or other setting methods are also possible, and the present application does not make any limitations. The water inlet pipe 151 and the water outlet pipe 152 can be connected to the pump assembly 15 in the arrangement shown in Figure 4 or can be connected to the pump assembly 15 in other arrangements, and the present application does not make any limitations.

[0092] As Figure 4 shown, the spray fan 100 further includes a second motor 153 for driving the pump assembly 15 to operate. The second motor 153 is connected to the pump assembly 15, and the second motor 153 is used to drive the pump assembly 15 to pump the water in the first accommodation cavity 121b to the nozzle 13, that is, by driving the pump assembly 15 with the second motor 153, the water inlet pipe 151 can obtain water from the first accommodation cavity 121b and pump the obtained water to the nozzle 13 through the water outlet pipe 152. Among them, the operating power of the pump assembly 15 is less than or equal to 10W.

[0093] As Figure 5 shown, the spray fan 100 further includes a battery assembly 16. The battery assembly 16 is arranged in the second accommodation cavity 122b. The battery assembly 16 includes a battery pack 161 and a battery compartment 162. Since the pump assembly 15 is also arranged in the second accommodation cavity 122b, in order to improve the safety of the spray fan 100, a partition 154 can be provided between the pump assembly 15 and the battery assembly 16, so that when the pump assembly 15 fails and there is a water leakage problem, the partition 154 can prevent the leaked water from flowing to the battery assembly 16 and ensure the power supply safety of the battery assembly 16.

[0094] Alternatively, in some embodiments, the second housing 122a or the first housing 121a is formed with an access port, and the battery pack 161 is detachably connected to the access port. When the battery pack 161 is installed in the connection port, at least part of the battery pack 161 is exposed. Or rather, when the battery pack 161 is installed in the connection port, the battery pack 161 is located outside the first accommodation cavity and the second accommodation cavity, which is convenient for users to observe the remaining power of the battery pack.

[0095] The battery pack 161 is used to supply power to the first motor 112 and the second motor 153, so that the first motor 112 drives the fan blade 111 to rotate, and the second motor 153 drives the pump assembly 15 to operate. Among them, the battery pack 161 is connected to the circuit board assembly 155 and further supplies power to the first motor 112 and the second motor 153 through the circuit board assembly 155. The circuit board assembly 155 is arranged in the second accommodation cavity 122b. Optionally, the circuit board assembly 155 includes a circuit board and a circuit board box. The circuit board is installed in the circuit board box. When the circuit board is installed in the circuit board box, sealant can also be injected into the circuit board box, which can improve the waterproof performance of the circuit board assembly 155. Optionally, the circuit board assembly 155 can also only include a circuit board, which is not limited in this application.

[0096] In some embodiments, the battery pack 161 is detachably connected to the body 12, and the battery pack 161 is detachable from the battery compartment 162 in the second accommodation cavity 122b. When the battery pack 161 is installed in the second accommodation cavity 122b, in the up-down direction, at least part of the first accommodation cavity 121b is located above the battery pack 161, so that the battery pack 161 is located below the interior of the body 12, improving the stability of the spray fan 100. When the battery pack 161 is not installed in the second accommodation cavity 122b and is removed from the spray fan 100, the battery pack 161 can also be used to supply power to other power tools.

[0097] In some embodiments, the battery pack 161 is inserted into the second accommodation cavity 122b along the left-right direction. As Figure 6 shown, in order to make the thickness of the body 12 of the spray fan 100 thinner, when the battery pack 161 is installed in the second accommodation cavity 122b, in the direction along the fan shaft 1111 of the fan blade 111, the thickness of the battery pack 161 is less than or equal to 90 mm. For example, the thickness of the battery pack 161 can be 75 mm, or 85 mm, etc. That is, with the thinnest surface of the battery pack 161 facing the side of the body 12, the battery pack 161 is horizontally installed in the second accommodation cavity 122b. Therefore, the installation direction of the battery compartment 162 in the second accommodation cavity 122b matches that of the battery pack 161. As Figure 5As shown in the figure, a first movable opening 122c is formed on the side surface of the second housing 122a. By opening the first movable opening 122c, the battery pack 161 can be inserted into the second accommodation cavity 122b in a left-to-right or right-to-left direction. Among them, the opening area of the first movable opening 122c is larger than the area of the thinnest surface of the battery pack 161. Optionally, the number of battery packs 161 can be greater than or equal to one, the nominal voltage of the battery pack 161 is greater than or equal to 6V and less than or equal to 56V. In some embodiments, the nominal voltage of the battery pack is equal to or equal to 3.6V and less than or equal to 36V. In some embodiments, the nominal voltage of the battery pack 161 is greater than or equal to 6V and less than or equal to 36V. In some embodiments, the nominal voltage of the battery pack 161 is greater than or equal to 6V and less than or equal to 24V. The working current of the battery pack 161 is greater than or equal to 0.5A and less than or equal to 5A. For example, when the nominal voltage of a single battery pack is 4V, and the number of battery packs 161 is 2 and the two battery packs are connected in series, the nominal voltage of the battery assembly 16 is 8V.

[0098] In some embodiments, as Figure 7 shown, a power display component 123 is further provided on the body 12 of the spray fan 100, and the power state of the battery pack 161 is displayed through the power display component 123. The power display component 123 can be arranged on the second housing 122a, so as to be relatively close to the battery pack 161, which is convenient for displaying the power state of the battery pack 161. Among them, the power display component 123 can be composed of multiple display windows. When the battery pack 161 is in a full charge state, all the multiple display windows remain lit. When the battery pack 161 is in a half charge state, half of the multiple display windows are in a long-lit state and the other half are in a long-dark state. In addition, the power display component 123 can also display the power state of the battery pack 161 in other ways, which is not limited in this application.

[0099] As Figure 7 shown, the spray fan 100 further includes a water mist adjustment component 17. The water mist adjustment component 17 is arranged on the second housing 122a of the spray fan 100. Among them, for the convenience of user operation, the water mist adjustment component 17 is arranged on the front side (front surface) of the spray fan 100, that is, on the front side (front surface) of the second housing 122a. The water mist adjustment component 17 is connected to the pump component 15 and is used to control the amount of water pumped by the pump component 15 from the first accommodation cavity 121a to the nozzle 13. Optionally, the water mist adjustment component 17 can be as Figure 7The shown knob-type component controls the amount of water pumped by the pump component 15 to the nozzle 13 by rotating the knob. For example, when the water mist adjustment component 17 rotates to the far left, the pump component 15 is in a non-operating state, that is, the amount of water pumped by the pump component 15 to the nozzle 13 is 0. When the water mist adjustment component 17 rotates to the far right, the pump component 15 is in an operating state and at the maximum operating gear, that is, the amount of water pumped by the pump component 15 to the nozzle 13 is the largest. In addition, when the water mist adjustment component 17 rotates to the far left, the pump component 15 can also be in an operating state and at the maximum operating gear; when the water mist adjustment component 17 rotates to the far right, the pump component 15 is in a non-operating state.

[0101] As Figure 8As shown, the spray fan 100 further includes an angle adjustment component 19. The angle adjustment component 19 is disposed on the body 12 and is used to adjust the operating angle of the spray fan 100, that is, to adjust the standing angle of the spray fan 100. Among them, the angle adjustment component 19 can adjust the operating angle of the spray fan 100 to be greater than or equal to 0 degrees and less than or equal to 90 degrees. That is, the angle adjustment component 19 can adjust the standing angle of the spray fan 100 to be greater than or equal to 0 degrees and less than or equal to 90 degrees, so that the spray fan 100 can be supported and stand at any angle between standing on a certain plane (standing angle equal to 90 degrees) and lying flat on a certain plane (standing angle equal to 0 degrees). To not affect the normal operation of the spray fan 100, the angle adjustment component 19 is disposed at the rear side of the spray fan 100, that is, the back surface of the body 12. The angle adjustment component 19 includes a fixed end 191 and a movable end 192. To ensure the stability of the angle adjustment component 19 in adjusting the standing angle of the spray fan 100, the fixed end 191 of the angle adjustment component 19 is fixed on the back surface of the first housing 121a. Specifically, the fixed end 191 of the angle adjustment component 19 is respectively fixed at both ends of the back surface of the first housing 121a on the left and right sides of the fan assembly 11. Among them, the connection line of the two ends can be parallel to the plane along the left-right direction, or can be not parallel to the plane along the left-right direction, as long as the angle adjustment component 19 can stably support the spray fan 100. The angle adjustment component 19 is a foldable component, that is, a retractable component. A storage groove 193 matching the angle adjustment component 19 is provided on the back surface of the body 12. The storage groove 193 includes both a part disposed on the back surface of the first housing 121a and a part disposed on the back surface of the second housing 122a. When the angle adjustment component 19 is retracted into the storage groove 193, the angle adjustment component 19 does not protrude from the outer surface of the body 12, making the outer surface of the body 12 tend to be flat, so that the spray fan 100 is more easily stored. Optionally, the angle adjustment component 19 can be a Figure 8 hinged support leg as shown, or any other component form that can play a supporting role. The present application does not make a limitation.

[0102] In some embodiments, the volume (water storage capacity) of the first accommodating cavity 121b is less than or equal to 20L. For example, the volume of the first accommodating cavity 121b can be 3.5L. In some embodiments, the volume of the first accommodating cavity 121b is greater than or equal to 2L and less than or equal to 15L. Alternatively, in some embodiments, the volume of the first accommodating cavity 121b is greater than or equal to 2L and less than or equal to 10L.

Optionally, when the volume of the first accommodating cavity 121b is 18L, the corresponding length of the first accommodating cavity 121b is less than or equal to 550mm, the width of the first accommodating cavity 121b is less than or equal to 350mm, and the thickness of the first accommodating cavity 121b is less than or equal to 150mm. Among them, the first accommodating cavity 121b can be made by blow molding process, making the body 12 lighter in weight and the spray fan 100 more portable and easier to carry.

[0103] In some embodiments, the first accommodating cavity 121b is made of a light-transmitting material, and the material of the first housing 121a corresponding to the first accommodating cavity 121b is a light-transmitting material, so that the first accommodating cavity 121b can display the water storage capacity of the spray fan 100. Among them, the light-transmitting material can be a semi-transparent material. Since the first accommodating cavity 121b is made of a light-transmitting material, when there is a light source, the first accommodating cavity 121b can scatter the light source, thereby providing area lighting for the area where the spray fan 100 is located. In addition, the first accommodating cavity 121b can also be made of an opaque material, which is not limited in this application.

[0104] In some embodiments, the spray fan 100 further includes a lighting device 20, such as Figure 9As shown, the light-emitting device 20 can be installed at the connection between the first housing 121a and the fan assembly 11. The light-emitting device 20 can provide area lighting for the area where the spray fan 100 is located through the first accommodation cavity 121b. Among them, the light-emitting device 20 can be installed at the front connection between the first housing 121a and the fan assembly 11, or at the back connection between the first housing 121a and the fan assembly 11. This application does not make a limitation. Optionally, the light-emitting device 20 can be installed around the fan assembly 11 for one week (360 degrees), or the light-emitting device 20 can also be installed only around the fan assembly for 10 degrees. In addition, the light-emitting device 20 can also be any degree greater than or equal to 0 degrees and less than or equal to 360 degrees around the fan assembly. This application does not make a limitation. Among them, the light-emitting device 20 is powered by the battery pack 161.

[0105] As Figure 10 shown, the spray fan 100 further includes a handle assembly 21, and the handle assembly 21 is arranged on the first housing 121a corresponding to the first accommodation cavity 121b. Among them, the handle assembly 21 and the first housing 121a can be integrated and jointly manufactured by blow molding. In addition, the handle assembly 21 can also not be integrated with the first housing 121a. This application does not make a limitation.

[0106] As Figure 10As shown, the handle assembly 21 and the water injection port 14 can both be located on the upper side of the first housing 121a, and the handle assembly 21 and the water injection port 14 are on the same side, making it more convenient to fill water into the spray fan 100. Among them, the water injection port 14 includes a filtering assembly 142. The filtering assembly 142 is located inside the water injection port 14 and can filter foreign matters in the water injected into the first accommodation cavity 121b, so that the nozzle 13 is not easily blocked by foreign matters during use. Among them, the filtering assembly 142 is detachably connected in the water injection port 14, which is convenient for regularly cleaning the filtering assembly 142. Optionally, when the volume in the first accommodation cavity 121b is 3.5L, the nominal voltage of the battery pack 161 is 20V, and the electricity storage capacity of the battery pack 161 is 2.0Ah, the battery pack 161 can support the spray fan 100 to operate for a time greater than or equal to 1 hour when the water storage in the first accommodation cavity 121b is the largest. That is, when the water storage in the first accommodation cavity 121b of the spray fan 100 is the largest, the operating wind speed of the spray fan 100 is the largest (i.e., the operating power of the fan assembly 11 is 15W), and the water output of the nozzle 13 is the largest (i.e., the operating power of the pump assembly 15 is 5W), the battery pack 161 supports the spray fan 100 to operate for 2 hours.

Optionally, when the volume in the first accommodation cavity 121b is 3.5L, the nominal voltage of the battery pack 161 is 12V, and the electricity storage capacity of the battery pack 161 is 2.0Ah, the battery pack 161 can support the spray fan 100 to operate for a time greater than or equal to 1 hour when the water storage in the first accommodation cavity 121b is the largest.That is, when the water storage amount in the first accommodating cavity 121b of the spray fan 100 is the largest, the wind speed at which the spray fan 100 operates is the smallest (i.e., the operating power of the fan assembly 11 is 3W), and the water output of the nozzle 13 is the least (i.e., the operating power of the pump assembly 15 is 3W), the battery pack 161 can support the spray fan 100 to operate for 3 hours.

[0107] As Figure 11 shown, the first accommodating cavity 121b is arranged around the fan assembly 11. In the circumferential direction, the first accommodating cavity 121b forms an angle A around the fan assembly 11, and the angle of the angle A is greater than or equal to 180 degrees. Optionally, as Figure 12 shown, the angle A of the first accommodating cavity 121b around the fan assembly 11 can be 360 degrees, and the first accommodating cavity 121b surrounds the fan assembly 11 for one week, so that the fan assembly 11 is supported in the frame of the first housing 121a corresponding to the first accommodating cavity 121b. In some embodiments, in the circumferential direction, the first accommodating cavity 121b forms an angle A around the fan assembly 11 that is greater than or equal to 90 degrees. In some embodiments, in the circumferential direction, the first accommodating cavity 121b forms an angle A around the fan assembly 11 that is greater than or equal to 120 degrees. In some embodiments, in the circumferential direction, the first accommodating cavity 121b forms an angle A around the fan assembly 11 that is greater than or equal to 300 degrees.

[0108] As Figure 13 shown, the nozzle 13 is arranged on the fuselage 12, specifically on the front side of the first housing 121a, that is, the front of the fuselage 12. Optionally, the nozzle 13 is detachable and can be removed from the first housing 121a when a usage failure occurs. Optionally, the nozzle 13 can also be retractable. A storage groove 131 matching the nozzle 13 can be arranged on the first housing 121a. When the nozzle 13 does not need to spray water mist, the nozzle 13 can be stored in the storage groove 131. And when the nozzle 13 is stored in the storage groove 131, the nozzle 13 does not protrude from the outer surface of the fuselage 12, so that the outer surface of the fuselage 12 remains flat, which is convenient for the storage of the spray fan 100. Optionally, the storage groove 131 can be arranged at the position as Figure 13 shown, or can be arranged at other positions on the front of the fuselage 12 where the nozzle 13 can be stored, and this application does not make a limitation. Optionally, the position of the nozzle 13 can be at the lowest position at the junction of the fan assembly 11 and the first housing 121a as Figure 13 shown, that is, the lowest position passed by the rotation of the fan assembly 11. The position of the nozzle 13 can also be any position at the junction of the fan assembly 11 and the first housing 121a, and this application does not make a limitation.

[0109] In some embodiments, the diameter of the fan blade 111 of the fan assembly 11 is greater than or equal to 5 inches and less than or equal to 20 inches. For example, the diameter of the fan blade 111 of the fan assembly 11 can be 6 inches or 7 inches. In some embodiments, the diameter of the fan blade 111 of the fan assembly 11 is greater than or equal to 6 inches and less than or equal to 15 inches. In some embodiments, the diameter of the fan blade 111 of the fan assembly 11 is greater than or equal to 6 inches and less than or equal to 10 inches. When the fan assembly 11 is operating, the operating power of the fan assembly 11 is greater than or equal to 3W and less than or equal to 15W, and the wind speed at which the fan assembly operates is greater than or equal to 2.5 m / s. For example, the wind speed at which the fan assembly operates can be 6.4 m / s. In some embodiments, the operating power of the fan assembly 11 is greater than or equal to 3W and less than or equal to 12W. Alternatively, the operating power of the fan assembly 11 is greater than or equal to 3W and less than or equal to 10W.

[0110] As Figure 13 and Figure 14 shown, the fan assembly 11 further includes a front fan grille 113 and a rear fan grille 114. Among them, neither the front fan grille 113 nor the rear fan grille 114 protrudes from the outer surface of the body 12, that is, the front fan grille 113 does not protrude from the front side (front surface) of the body 12, and the rear fan grille 114 does not protrude from the rear side (back surface) of the body 12, so that the outer surface of the spray fan 100 remains flat, making the spray fan 100 easier to store. In some embodiments, the nozzle 13 is provided on the fan assembly 11. Specifically, the nozzle 13 can be provided on the front fan grille 113 so that the nozzle 13 does not affect the normal operation of the fan assembly 11. Optionally, the nozzle 13 can be detachable. Optionally, the nozzle 13 can also be retractable. When the nozzle 13 is retractable, as Figure 15 shown, a nozzle storage groove 132 matching the nozzle 13 is provided on the front fan grille 113. When the nozzle 13 does not need to spray water mist, the nozzle 13 is stored in the nozzle storage groove 132, and when the nozzle 13 is stored in the storage groove 132, the nozzle 13 does not protrude from the outer surface of the body 12, making the outer surface of the body 12 remain flat, so that the spray fan 100 is easier to store. At the same time, when the spray fan 100 falls forward, the nozzle 13 can be stored in the nozzle storage groove 132, so that the nozzle 13 will not be damaged, improving the service life of the nozzle 13. Optionally, the present application does not limit the position of the nozzle 13 on the front fan grille 113, and the nozzle 13 can be located at any suitable working position on the front fan grille 113. Optionally, the storage groove 132 can be set at the position as Figure 15 shown, or can be set at other positions on the front of the front fan grille 113 where the nozzle 13 can be stored, and the present application does not make a limitation.

[0111] In some embodiments, the number of nozzles 13 can be 1 as shown Figure 13 in the figure. The number of nozzles 13 can also be 2, 3, or any positive integer greater than or equal to 1, which is not limited in this application. In some embodiments, the nozzles 13 can intermittently spray water mist, so as to save the water in the first accommodating cavity 121b while ensuring the function of the spray fan 100. The nozzles 13 can also continuously spray water mist, which is not limited in this application.

[0112] In some embodiments, the front fan grille 113 is recessed to a certain extent compared with the front of the fuselage 12, so that the light-emitting device 20 can be installed on the front fan grille 113. The rear fan grille 114 can also be recessed to a certain extent compared with the rear of the fuselage 12, so that the light-emitting device 20 can be installed on the rear fan grille 114. In addition, the light-emitting device 20 can be installed on both the front fan grille 113 and the rear fan grille 114, which is not limited in this application.

[0113] The currently existing spray fans need to be externally connected to a water bucket or a water pipe when in use, which is not convenient when the spray fans are in use. And once separated from the water bucket or the water pipe, the spray fans cannot spray. The spray fan 100 in this application makes the spray fan 100 more convenient to use by using the fuselage 12 as both the frame for supporting the fan assembly 11 and the water storage device of the spray fan 100. Even when the spray fan 100 is far from the water source, the spray fan 100 can rely on the water stored in the fuselage 12 to perform the spraying operation. And when the spray fan 100 needs to be refilled with water, the entire spray fan 100 can be directly moved for refilling, without separating the spray fan from the water bucket as in the prior art and refilling the water bucket. At the same time, when the spray fan needs to be moved, the spray fan 100 in this application is also more convenient to move. In addition, since the fuselage 12 of the spray fan 100 in this application has a cubic structure, the spray fans 100 can be neatly arranged when being stored, which is convenient for storage.

[0114] In some embodiments, as Figure 16As shown, since the left and right sides of the first accommodation cavity 121b of the spray fan 100 are two parallel planes, that is, the left and right sides of the first housing 121a are two parallel planes, the spray fan 100 can be placed sideways on the window sill 21, and the spray fan 100 can be fixed by the clamping of the window sill 21 and the window 22. The spray fan 100 is used as a window sash. Optionally, in the up and down direction, the length of the body 12 of the spray fan 100 is less than or equal to 600 mm, and in the left and right direction, the width of the body 12 is less than or equal to 400 mm. Optionally, in the up and down direction, the length of the body 12 of the spray fan 100 is less than or equal to 600 mm, and in the front and back direction, the thickness of the body is less than or equal to 200 mm. In some embodiments, the length of the body 12 of the spray fan 100 is less than or equal to 500 mm, in the left and right direction, the width of the body 12 is less than or equal to 300 mm, and in the front and back direction, the thickness of the body is less than or equal to 130 mm. In some embodiments, the length of the body 12 of the spray fan 100 is less than or equal to 450 mm, in the left and right direction, the width of the body 12 is less than or equal to 300 mm, and in the front and back direction, the thickness of the body is less than or equal to 110 mm.

[0115] In some embodiments, the spray fan 100 can be powered by the battery pack 161. In some embodiments, the spray fan 100 includes a plug assembly, and the spray fan 100 can also be powered by the cooperation of the plug assembly and the socket.

[0116] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form. Any technical solutions obtained by using equivalent replacements or equivalent transformations fall within the protection scope of the present application.
