Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an atomizing fan. Background Technology

[0002] In hot weather, misting fans are often used to quickly cool down the air by blowing water mist. These misting fans are equipped with a fixed water tank. In order to make the overall shape and size of the misting fan neat and aesthetically pleasing, other components need to be designed to avoid the location of the water tank, which leads to design limitations, production and assembly inconveniences, and other problems. Moreover, when the misting humidification function is not needed, the water tank still needs to be used.

[0003] In addition, the spray assembly used to form water mist needs to be placed in the airflow path driven by the fan to deliver the water mist forward. Typically, the spray assembly is fixed inside the fan's mesh cover, which is very inconvenient during assembly. Some spray assemblies are fixed in the center of the mesh cover where the airflow does not pass, resulting in poor water mist delivery.

[0004] In addition, to make it convenient for users to place the fan in locations without sockets, some fans are equipped with batteries for power supply. When the battery is depleted, the fan needs to be moved to a socket for charging, which is inconvenient. To address this, removable battery installation methods have emerged in related technologies. However, the disassembly structure of ordinary batteries is relatively complex, and the electrical connection stability is poor. When the battery is impacted, it is easy to fall off or have poor conductivity. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the purpose of this invention is to provide a misting fan that can be detachably installed with a water bucket to improve ease of use, versatility, and freedom of movement.

[0006] A misting fan according to an embodiment of the present utility model includes: a fan body, a plurality of nozzles installed on the mesh cover of the fan body, the nozzles being connected to a water pump via pipes, the input end of the water pump being connected to a water suction pipe that can extend downward to the lower part of the fan body, and the bottom of the fan body being provided with a mounting base for placing in the opening of a water bucket, the mounting base being provided with a limiting mechanism that cooperates with the edge of the opening of the water bucket.

[0007] The atomizing fan according to the embodiments of the present utility model has at least the following beneficial effects:

[0008] When using the atomizing function, users simply fill a water bucket with water, place the fan's mounting base at the opening of the bucket, and use a limiting mechanism to position or limit the bucket, preventing separation of the bucket and fan from external force or vibration during operation. The water pump extends downwards to the bottom of the bucket. When the fan is working, the pump delivers the water from the bucket to the nozzle to form a mist. When the atomizing function is not needed, the bucket can be removed. This detachable installation method improves convenience, versatility, and freedom of use.

[0009] In some embodiments of this utility model, the limiting mechanism includes a limiting groove formed on the bottom surface of the mounting base. The inner peripheral wall of the limiting groove can contact the outer peripheral wall of the opening of the water bucket. At least two limiting blocks are provided in the limiting groove, which are distributed around the central circumference of the limiting groove. The limiting blocks can abut against the inner peripheral wall of the opening of the water bucket to prevent the water bucket from detaching from the mounting base.

[0010] In some embodiments of this utility model, the three limiting blocks are evenly distributed circumferentially around the center of the limiting groove, and the limiting blocks and the inner peripheral wall of the limiting groove define an insertion gap that is wider at the bottom and narrower at the top.

[0011] In some embodiments of this utility model, the bottom of the limiting sink abuts against a portion of the upper surface of the water bucket, and the dimension of the mounting base along a certain direction of the horizontal plane is smaller than the diameter of the water bucket, so that the opening of the water bucket is exposed on the side of the mounting base.

[0012] In some embodiments of this utility model, at least two nozzles are arranged circumferentially at a uniform interval around the center of the mesh cover of the fan body. Each nozzle includes a connecting seat fixed to the outer peripheral edge of the mesh cover. The connecting seat is provided with an adapter pipe. One end of the adapter pipe is detachably connected to a nozzle. The other end of the adapter pipe is provided with a flexible hose extending along the inner wall of the mesh cover between it and the water pump.

[0013] In some embodiments of this utility model, the nozzle is threadedly connected to the adapter pipe, and a sealing bead, a spring and an atomizing nozzle are arranged sequentially inside the adapter pipe. One end of the spring drives the sealing bead to elastically abut against the internal channel of the adapter pipe, and the other end of the spring drives the atomizing nozzle to elastically abut against the nozzle. A fluid gap communicating with the interior of the adapter pipe is provided between the atomizing nozzle and the nozzle.

[0014] In some embodiments of this utility model, a positioning pressure plate is installed on the inner circumference of the mesh cover, and the positioning pressure plate is provided with a channel for the hose to pass through.

[0015] In some embodiments of this utility model, the fan body has a storage battery, which is electrically connected to the motor of the fan body and the water pump through a control module, and the storage battery has a charging port.

[0016] In some embodiments of this utility model, the side of the fan body is recessed and has an open mounting cavity.

[0031] See Figures 1 to 3The present invention discloses an atomizing fan, comprising: a fan body 100, wherein a plurality of nozzles 200 are installed on a mesh cover 110 of the fan body 100, the nozzles 200 are connected to a water pump 300 via pipes, the input end of the water pump 300 is connected to a water suction pipe 400 that extends downward to the bottom of the fan body 100, and the bottom of the fan body 100 is provided with a mounting base 120 for placing in the opening of a water bucket 10, the mounting base 120 being provided with a limiting mechanism 500 that cooperates with the edge of the opening of the water bucket 10.

[0032] When using the atomizing function, the user simply fills a water bucket 10 with water, places the mounting base 120 of the fan body 100 at the opening of the water bucket 10, and uses the limiting mechanism 500 to position or limit the water bucket 10, preventing separation of the water bucket 10 and the fan body 100 due to external force or vibration during operation. The water suction pipe 400 extends downward to the bottom of the water bucket 10. When the fan body 100 is working, the water pump 300 delivers the water in the water bucket 10 to the nozzle 200 to form a water mist, which is then blown forward by the wind. The water bucket 10 is a common household tool, requiring no special equipment and offering high convenience. Moreover, with a similar opening diameter, it is suitable for water buckets 10 of different heights. When the atomizing function is not needed, the water bucket 10 can be removed, reducing the size of the atomizing fan and increasing flexibility.

[0033] See Figure 2 In some embodiments of this utility model, the limiting mechanism 500 includes a limiting groove 510 formed on the bottom surface of the mounting base 120. The inner peripheral wall of the limiting groove 510 can contact the outer peripheral wall of the opening of the water bucket 10. At least two limiting blocks 520 are provided in the limiting groove 510, which are distributed around the central circumference of the limiting groove 510. The limiting blocks 520 can abut against the inner peripheral wall of the opening of the water bucket 10 to prevent the water bucket 10 from detaching from the mounting base 120. The above structure can prevent the water bucket 10 from displacing relative to the fan body 100 in its radial direction, thereby ensuring the stability of the product.

[0034] See Figure 2 In some embodiments of this utility model, in order to improve the reliability of the limiting mechanism 500, the three limiting blocks 520 are evenly distributed circumferentially around the center of the limiting groove 510. In order to facilitate the installation and disassembly of the water bucket 10, the limiting block 520 and the inner peripheral wall of the limiting groove 510 define an insertion gap 530 that is wider at the bottom and narrower at the top, so that the opening of the water bucket 10 can be easily inserted or pulled out along the insertion gap 530.

[0035] In some embodiments of this utility model, the bottom of the limiting groove 510 abuts against a portion of the upper surface of the water bucket 10, and the dimension of the mounting base 120 in a certain direction along the horizontal plane is smaller than the diameter of the water bucket 10, so that the opening of the water bucket 10 is exposed on the side of the mounting base 120. It is understood that draining some of the water from the water bucket 10 will cause a decrease in the air pressure inside the water bucket 10; the above arrangement can prevent the water bucket 10 from collapsing.

[0036] See Figure 1 and Figure 3 In some embodiments of this utility model, at least two nozzles 200 are arranged circumferentially around the center of the mesh cover 110 of the fan body 100, which facilitates more uniform water mist contained in the airflow. Each nozzle 200 includes a connecting seat 210 fixed to the outer peripheral edge of the mesh cover 110. An adapter pipe 220 is provided on the connecting seat 210. One end of the adapter pipe 220 is detachably connected to a nozzle 230, and the other end of the adapter pipe 220 is connected to the water pump 300, with a flexible hose extending along the inner wall of the mesh cover 110. It should be noted that the hose extends along the inner wall of the mesh cover 110 without interfering with the fan blades of the fan body 100, and the detachable nature of the nozzle 230 facilitates cleaning and maintenance when the nozzle 230 becomes clogged.

[0037] See Figure 5 In some embodiments of this utility model, the nozzle 230 is threadedly connected to the adapter pipe 220. A sealing bead 240, a spring 250, and an atomizing nozzle 260 are sequentially arranged inside the adapter pipe 220. One end of the spring 250 drives the sealing bead 240 to elastically abut against the internal channel of the adapter pipe 220, and the other end of the spring 250 drives the atomizing nozzle 260 to elastically abut against the nozzle 230. A fluid gap communicating with the interior of the adapter pipe 220 is provided between the atomizing nozzle 260 and the nozzle 230. It can be understood that when the sealing bead 240 and the spring 250 form a one-way valve, when water enters the adapter pipe 220, it pushes open the sealing bead 240, compresses the spring 250, and allows water to be sprayed outwards through the fluid gap.

[0038] See Figure 3 In some embodiments of this utility model, in order to prevent the flexible hose from deforming or shifting and interfering with the fan blades of the fan body 100, a positioning pressure plate 600 is installed on the inner circumference of the mesh cover 110, and the positioning pressure plate 600 is provided with a channel 610 for the flexible hose to pass through. Specifically, the positioning pressure plate 600 is fixed to the mesh cover 110 by means of a threaded connection.

[0039] See Figure 4In some embodiments of this utility model, to facilitate user placement of the fan in locations without power outlets, the fan body 100 includes a battery 700. The battery 700 is electrically connected to the motor of the fan body 100 and the water pump 300 via a control module. The battery 700 has a charging port, which is used to charge the battery 700 when its power is depleted. The control module can select whether to power the water pump 300, thereby enabling or disabling the atomization function. Furthermore, the control module includes charging and discharging circuits connected to the battery 700.

[0040] See Figure 4 In some embodiments of this utility model, the fan body 100 has a recessed mounting cavity 130 with an open opening on its side. Sliding mounting grooves 140 are provided on both sides of the mounting cavity 130 along its depth direction. A first electrical contact 150 is provided on the bottom wall of the mounting cavity 130 along its depth direction. The battery 700 is electrically connected to the battery holder 710. The battery holder 710 has a second electrical contact that cooperates with the first electrical contact 150. The battery holder 710 has a guide protrusion 720 that cooperates with the sliding mounting groove 140. When installing the battery 700, the guide protrusion 720 of the battery holder 710 slides along the sliding mounting groove 140 until the first electrical contact 150 and the second electrical contact come into contact. When removing the battery 700, the battery holder 710 and the battery 700 can be pulled out together from the mounting cavity 130. This method is convenient for installation and removal, facilitates charging, and provides high electrical connection stability.

[0041] See Figure 4 In some embodiments of this utility model, in order to protect the battery 700 and achieve waterproofing, a switch cover 800 that can be opened or closed is rotatably provided at the opening of the mounting cavity 130, and a waterproof sealing ring 810 is provided between the switch cover 800 and the fan body 100.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
