Description

Technical Field

[0001] This utility model relates to the field of industrial fans, specifically to a mobile spray fan. Background Technology

[0002] Industrial fans are large-scale mechanical devices specifically designed to meet the needs of large-area, high-intensity ventilation. Their core function is to improve ambient air quality, regulate temperature, and promote airflow through powerful air circulation. They are widely used in open spaces such as factory workshops, warehouses, logistics centers, stadiums, and farms. These fans typically use large blades several meters in diameter, driven by high-power motors, to produce a three-dimensional airflow effect covering thousands of square meters. The airflow is evenly distributed and naturally gentle, effectively reducing indoor temperature while avoiding the discomfort caused by the direct blowing of traditional small fans.

[0003] Industrial fans are designed with a focus on a balance between durability and energy efficiency. The fan blades are mostly made of aerospace-grade aluminum alloy or high-strength engineering plastics and undergo precise dynamic balancing to reduce vibration and noise. The motors adopt a dustproof and waterproof structure to meet the long-term operating requirements of complex industrial environments. Some models are also equipped with variable frequency speed control technology, which can flexibly adjust the wind speed according to the actual scenario, so as to meet the ventilation requirements of different seasons or processes while saving energy.

[0004] However, conventional industrial fans are large in size and are usually mounted directly on the wall, which is not very convenient. In addition, they can only dissipate heat by blowing air, so the cooling effect is poor. Utility Model Content

[0040] Example

[0041] Please refer to Figure 1-9As shown, this embodiment provides a mobile spray fan, including a water tank base 1, a fan body 2, and a spray assembly 3. The fan body 2 is fixed to the water tank base 1; the spray assembly 3 includes a water pump 31 and a spray water pipe 32, with the water pump 31 fixed to the water tank base 1. The inlet of the water pump 31 is connected to the inside of the water tank, and the outlet of the water pump 31 is connected to the spray water pipe 32, which is located on the air inlet side 214 or the air outlet side 215 of the fan body 2. A sliding assembly 4 is provided at the bottom of the water tank base 1.

[0042] The fan body 2 is fixed on the water tank base 1. The sliding component 4 at the bottom of the water tank base 1 improves the overall flexibility and facilitates moving the fan position according to usage requirements. Furthermore, the fan body 2 and the water tank base 1 are two independent entities, which facilitates classified maintenance during the inspection process and reduces maintenance costs. The water pump 31 draws water from the water tank base 1. In this embodiment, the spray pipe 32 is equipped with a nozzle 33, and the water is sprayed out through the spray pipe 32 and the nozzle 33. The sprayed water droplets are located on the airflow path of the fan body 2 and move with the airflow, effectively improving the overall cooling effect.

[0043] Please refer to Figure 4 and Figure 5 As shown, specifically, the water tank base 1 is a one-piece molded water tank base 1, with a reinforcing channel 11 extending through the top and bottom surfaces of the water tank base 1. The one-piece molded water tank base 1 effectively improves its structural strength, ensuring it can provide stable support for the blower body 2 and enhancing the operational stability of the mobile spray blower. Simultaneously, the reinforcing channel 11 connects the upper and lower bottom surfaces of the water tank, further improving the structural strength of the water tank base 1. Furthermore, the bottom of the water tank base 1 is provided with downward-protruding reinforcing ribs 12, which effectively increase the bottom hardness of the water tank base 1, thereby further enhancing its structural strength.

[0044] The top surface of the water tank base 1 is provided with a placement position 13 and a fixing position 14. The outer bottom of the fan body 2 is fixed to the placement position 13. The rear end of the fan body 2 is provided with an outwardly extending eave 213, which extends into the fixing position 14 and connects with the side wall of the fixing position 14. The eave 213 and the fan body 222 form an "L"-shaped contact structure. The eave 213 abuts against the fixing position 14, and the fixing position 14 applies a rearward supporting force to the eave 213, effectively improving the installation stability of the fan body 2.

[0045] Furthermore, a guide groove 141 is provided on the fixing position 14, and the guide groove 141 is located in the extension direction of the placement position 13. The front side of the protrusion 213 is attached to the front side wall of the guide groove 141, and the two ends of the protrusion 213 abut against the opposite side walls of the guide groove 141. The protrusion 213 is located in the guide groove 141. During the assembly process, the fan body 2 is placed on the placement position 13 and slides along the guide groove 141 until the protrusion 213 abuts against the front side wall of the guide groove 141, thus fixing the fan body 2. This effectively reduces the assembly difficulty. In the early stage of assembly, it is not necessary to perform detailed positioning of the fan body 2. During the sliding process, the position of the fan body 2 can be adjusted to ensure the accuracy of the installation position 15 of the fan body 2.

[0046] Specifically, the fan body 2 includes a fan housing 21 and a fan assembly 22 fixed inside the fan housing 21. The fan housing 21 includes a circular air outlet duct 211 and a rectangular air inlet duct 212 connected to each other. The circular air outlet duct 211 is fixed at the front end of the placement position 13, and the rectangular air inlet duct 212 is fixed at the rear end of the placement position 13. A protruding eave 213 is provided at the rear end of the rectangular air inlet duct 212. The rectangular air inlet duct 212 effectively increases the opening size of the air inlet side 214 of the fan body 2, while the circular air outlet duct 211 guides the airflow and its opening size is smaller than that of the air inlet side 214, effectively increasing the airflow velocity and improving the cooling effect.

[0047] Please refer to Figure 1 and Figure 9 As shown, in this embodiment, both the air inlet side 214 of the rectangular air inlet duct 212 and the air outlet side 215 of the circular air outlet duct 211 are provided with grid mesh 216. The spray water pipe 32 is provided on the air outlet side 215 of the fan body 2, that is, the spray water pipe 32 is fixed on the grid mesh 216 on the air outlet side 215 of the circular air outlet duct 211. This ensures that the water droplets are sprayed out in front of the fan assembly 22, avoiding the water droplets from affecting the working stability of the electrical components of the fan assembly 22. Similarly, the spray water pipe 32 can also be provided on the air inlet side 214 of the fan body 222, and the fan assembly 22 is waterproofed. The water droplets pass through the fan blades 2221 of the fan assembly 22, and the fan blades 2221 strike the water droplets, reducing their size and forming a water mist, further improving the cooling effect.

[0048] Please refer to Figure 1 and Figure 4 As shown, the top surface of the water tank base 1 has two opposing mounting positions 15, which are located on both sides of the circular air outlet duct 211. The water pump 31 is mounted on one of the mounting positions 15. The water pump 31 is installed by utilizing the dimensional difference between the circular air outlet duct 211 and the water tank base 1, thus making full use of the assembly space on the top surface of the water tank base 1.

[0049] The water tank base 1 has a water inlet 16 and a drain outlet 17. The water inlet 16 is located in another mounting position 15, and the drain outlet 17 is located on the bottom surface of the water tank base 1. The water inlet 16 is located on the top surface of the water tank base 1, ensuring that the entire internal space of the water tank base 1 can hold water. Compared to a side-mounted water inlet 16, this effectively increases the water storage capacity. Furthermore, placing the water inlet 16 in another mounting position 15 further improves the utilization rate of the top surface space of the water tank base 1.

[0050] Please refer to Figure 3 As shown, specifically, the fan assembly 22 includes a mounting frame 221 and a fan body 222 fixed on the mounting frame 221. The end of the mounting frame 221 extends outward and is fixedly connected to the inner wall of the rectangular air inlet duct 212. The fan body 222 includes fan blades 2221 and a motor 2222. The motor 2222 is fixed on the mounting frame 221 and passes through the mounting frame 221 to drive the fan blades 2221. The end of the mounting frame 221 is fixedly connected to the inner wall of the rectangular air inlet frame. The internal planar structure of the rectangular air inlet duct 212 is used to fit and fix the end of the mounting frame 221, effectively improving the installation stability of the mounting frame 221.

[0051] In this embodiment, the end of the mounting bracket 221 is provided with a first mounting through hole 2211, and a first connector (not shown in the figure) is fixed in the first mounting through hole 2211. The first connector passes through the first mounting channel and is fixedly connected to the inner sidewall of the rectangular air inlet duct 212. The inner sidewall of the rectangular air inlet duct 212 is fixed with two corresponding and outwardly protruding fitting plates 2121. The end of the mounting bracket 221 extends between the fitting plates 2121. A second mounting through hole 2122 is provided on the fitting plate 2121. A second connector is fixed in the second mounting through hole 2122. The second connector passes through the end of one fitting plate 2121 and the mounting bracket 221 and is fixedly connected to the other fitting plate 2121. The first connector connects the mounting bracket 221 and the rectangular air inlet duct 212 in the airflow direction, and the second connector connects the mounting bracket 221 and the fitting fixing plate 2121 on the rectangular air inlet duct 212 in the vertical airflow direction, forming a vertical fixing structure that fixes the mounting bracket 221 in multiple directions, further improving the installation stability of the mounting bracket 221. In this embodiment, both the first and second connectors are bolts and nuts.

[0052] Please refer to Figure 3 , Figure 6 and Figure 7As shown, in this embodiment, the mounting bracket 221 includes a first tube 2212, a second tube 2213, and a limiting piece 2214. Each of the first tube 2212, the second tube 2213, and the limiting piece 2214 has a insertion channel 2215 in its middle. The insertion channel 2215 is through which the drive end of the power supply 2222 passes and is connected to the fan blade 2221. An insertion notch 2216 is provided in the middle of the opposite side of the first tube 2212 and the second tube 2213. The insertion notch 2216 corresponds to the insertion channel 2215, and insertion slots 2217 are formed on both sides of the insertion notch 2216. The sidewalls of the first tube 2212 and the second tube 2213 form insertion pieces 2218 between the insertion slots 2217. The insertion notches 2216 of the first tube 2212 and the second tube 2213 are arranged opposite to each other. Simultaneously, the insertion piece 2218 of the first tube 2212 is inserted into the insertion slot 2217 of the second tube 2213, and the insertion piece 2218 of the second tube 2213 is inserted into the insertion slot 2217 of the first tube 2212, completing the insertion between the first tube 2212 and the second tube 2213. In the assembled state, the sides of the first tube 2212 and the second tube 2213 are on the same plane and abut against each other, forming a cross-shaped structure for mounting the fan body 222. The first tube 2212 and the second tube 2213 are provided with limiting channels 2219 on both sides of the insertion notch 2216 and the insertion channel 2215. The limiting piece 2214 has two corresponding limiting parts 2220 on one side. The limiting parts 2220 are inserted into the limiting channels 2219 on the same side of the first tube 2212 and the second tube 2213 to connect and limit the first tube 2212 and the second tube 2213, thereby improving the overall structural strength of the mounting bracket 221.

[0053] The sliding component 4 includes multiple casters, which are fixed around the bottom surface of the water tank base 1. In this embodiment, there are four casters. The four casters support the water tank base 1 around the bottom surface of the water tank base 1, effectively improving the movement stability of the water tank base 1.
