It atomizes the water in the water tank through a set atomization device first, and then blows the water mist to the user with the wind force of the fan to cool down. The spray hand-held fan has the characteristics of spray cooling, silent and portable, and is widely loved by consumers.

[0003] The spray fans in the prior art adopt the design methods of cotton swabs or single water tanks. For the fans using cotton swab spraying, it is necessary to interrupt the spraying and replace the cotton swab after using for a period of time. For the fans using single water tank spraying, it is also necessary to interrupt the spraying to replenish water to the water tank. The use is rather troublesome. Whether it is a spray fan with a cotton swab or a single water tank, there is a situation that the spraying needs to be interrupted and the water replenishment operation needs to be carried out on time during the use process, and the use process is inconvenient. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a negative pressure water absorption type spray fan, aiming to solve the technical problem that the spray fans in the prior art need to interrupt the spraying and carry out the water replenishment operation on time during the use process, and the use process is rather inconvenient.

[0005] To achieve the above purpose, the utility model proposes a negative pressure water absorption type spray fan, including:

[0006] A fan head, which includes a fan blade, a wind cover, and a mist outlet. The fan head is used for air outlet and / or mist outlet operations;

[0007] A water tank, which includes a main water source device and a secondary water tank. The main water source device is cooperatively installed outside the fan head, while the secondary water tank is installed inside the fan head;

[0008] A water pipe, which is arranged between the main water source device and the secondary water tank, and is used for connecting the main water source device and the secondary water tank and conducting water transmission between them;

[0009] An atomization device, which is installed on the fan head and is used for atomizing the water in the secondary water tank.

[0010] Further, the main water source device is a main water tank and / or an adapter ring.

[0011] Further, the main water tank is detachably installed outside the fan head, and both ends of the water pipe are respectively connected to the main water tank and the secondary water tank for water transmission.

[0012] Further, the adapter ring is fitted and connected to the outer end face of the fan head. The adapter ring is used to connect an external water bottle, and both ends of the water pipe are respectively connected to the external water bottle and the secondary water tank for water transmission and introduction therebetween.

[0013] Further, a sealing component is provided on the outer wall of the fan head corresponding to the secondary water tank. The sealing component is used to maintain the sealed state of the secondary water tank.

[0014] Further, the sealing component is a silica gel cover, and the silica gel cover is tightly fitted on the outer wall of the fan head.

[0015] Further, a gap is left between the silica gel cover and the fan head for conveniently opening or closing the silica gel cover.

[0017] Further, the fixing device includes a first fixing device provided at the main water source device.

[0018] Further, the fixing device includes a second fixing device provided at the secondary water tank.

[0019] In the technical solution of the present utility model, the water in the water tank is atomized by setting an atomizing device, and then the water mist is blown towards the user by the wind force of the fan head for cooling. This product adopts the principle of negative pressure water absorption. First, water is added to the main water tank and the secondary water tank, and the sealing component at the secondary water tank is covered to make the secondary water tank form a sealed state. When the product is in the spray working state, the atomizing device will spray the water in the secondary water tank. After the water is sprayed by the atomizing device, a negative pressure area with a relatively small pressure will be formed inside the secondary water tank. At this time, the water in the main water tank area with a relatively large pressure will flow into the secondary water tank with a small pressure through the water pipe, resulting in a back suction phenomenon, and finally negative pressure water absorption is formed. In addition, in addition to the detachable main water tank, an attached adapter ring can also be used to be compatible with commercially available conventional water bottles to achieve negative pressure water absorption and complete water replenishment, that is, the main water tank is replaced by using the adapter ring and an external water bottle.

[0030] The present utility model provides a negative pressure water absorption type spray fan.

[0031] In the embodiment of the present utility model, as Figures 1 to 5 shown, the negative pressure water absorption type spray fan includes a fan head 1 and a water tank 2. The fan head 1 includes a fan blade 11, a wind cover 12, and a mist outlet 13. The fan head 1 is used for air blowing and / or mist spraying operations. The water tank 2 includes a main water source device 21 and a secondary water tank 22. The main water source device 21 is cooperatively installed outside the fan head 1, while the secondary water tank 22 is installed inside the fan head 1. A water pipe 3 is provided between the main water source device 21 and the secondary water tank 22 for connecting the main water source device 21 and the secondary water tank 22 and transferring water between them. Additionally, there is an atomizing device 4 for atomizing the water stored in the secondary water tank 22, and the atomizing device 4 is installed in the fan head 1.

[0032] In this embodiment, the main water source device 21 is a main water tank 211 and / or an adapter ring 212. The function of the main water source device 21 is to store water and serve as a backup water source. After the water in the secondary water tank 22 is consumed, the secondary water tank 22 is replenished with water through the main water source device 21.

[0033] Specifically, the main water tank 211 is detachably installed outside the fan head 1. The two ends of the water pipe 3 are respectively connected to the main water tank 211 and the secondary water tank 22 for water transfer. When water replenishment is required, the main water tank 211 is detached from the fan head 1, and water is poured into the water injection port of the main water tank 211.

[0034] Specifically, the adapter ring 212 is cooperatively connected to the outer end face of the fan head 1. The adapter ring 212 is used to connect an external drinking water bottle. The two ends of the water pipe 3 are respectively connected to the external drinking water bottle and the secondary water tank 22 for water transfer between them. In this process, it can be understood that the adapter ring 212 and the external drinking water bottle actually replace the main water tank 211 and provide the function of replenishing water to the secondary water tank 22.

[0035] In this embodiment, a sealing component 5 is provided on the outer wall of the fan head 1 corresponding to the secondary water tank 22. The sealing component 5 is used to maintain the closed state of the secondary water tank 22. During use, after the main water source device 21 and the secondary water tank 22 are filled with water, the sealing component 5 is covered to make the secondary water tank 22 in a closed state.

[0036] Specifically, in a more preferred embodiment, the sealing component 5 is set as a silica gel cover. The silica gel cover is tightly fitted on the outer wall of the fan head 1. The silica gel cover has a strong fitting degree and is more convenient to use.

[0037] Further, a gap 6 is provided between the silica gel cover and the fan head 1 for conveniently opening or closing the silica gel cover. When the silica gel cover needs to be opened, the user uses a hand or a tool to resist the gap 6 and pull the silica gel cover upward with force. When closing, the gap 6 serves as a positioning component to close the silica gel cover by fitting it to the gap 6.

[0038] In this embodiment, a fixing device 7 for fixing the water pipe 3 is cooperatively arranged at the port of the water pipe 3. In a more preferred embodiment, the fixing device 7 is arranged below the power supply bin 8. In this position, enough moving space can be left for the water pipe 3.

[0039] In a more preferred embodiment, the power supply form of the present utility model is set to a charging mode. Specifically, a charging interface 14 is arranged on the side wall of the fan head 1 and is electrically connected to the power supply bin 8. More preferably, the charging interface 14 is set as a Type-C interface, which can be compatible with more charging scenarios. In some other embodiments, other commonly used charging interfaces 14 such as Micro-USB interfaces and Lightning interfaces are selected. At the same time, it can be understood that the present utility model can also adopt the method of replacing the battery for power supply, but it is a bit more troublesome than charging. The setting of the power supply form belongs to the prior art part and will not be elaborated here too much.

[0040] Specifically, the fixing device 7 includes a first fixing device 71 arranged at the main water source device 21. The first fixing device 71 winds the water pipe 3 around its surface. While fixing the water pipe 3, it also plays a role in storing the water pipe 3. In fact, it shortens the volume occupied by the water pipe 3 and can also extend the water pipe 3 when needed.

[0041] Specifically, the fixing device 7 includes a second fixing device 72 arranged at the secondary water tank 22. The second fixing device 72 docks one end of the water pipe 3 to enable it to be smoothly connected to the secondary water tank 22. The second fixing device 72 is actually a convex component on the side of the secondary water tank 22. Preferably, in order to prevent water leakage during the negative pressure water absorption process, the diameter of the second fixing device 72 needs to fit the diameter of the water pipe 3.

[0042] In this embodiment, a switch 15 is arranged on the side wall of the fan head 1. The switch 15 includes a wind power switch 151 and a spray switch 152. The wind power switch 151 controls the operation of the fan blade 11. Specifically, the fan blade 11 is started by the motor 9, and then wind power is generated by rotating the fan blade 11. The spray switch 152 controls the start and stop of the atomizing device 4. In a more preferred embodiment, the motor 9 is cooperatively provided with a motor bracket 91 to prevent the phenomenon of displacement during use. It can be understood that in some other embodiments, only one switch 15 can be arranged to start the fan blade 11 and the atomizing device 4 at the same time. However, since the applicable scenarios of this embodiment are few, it is not a preferred embodiment.

[0043] In this embodiment, a printed circuit board 10 is provided on the side of the fan head 1. Through the printed circuit board 10, information parameters such as the remaining power or usage time of the present utility model can be displayed. Preferably, a lens 101 is provided on the side wall of the fan head 1 to facilitate viewing the information parameters on the printed circuit board 10 during use.

[0044] The following content is the working principle description of the present utility model:

[0045] The present utility model has two main usage methods, that is, two embodiments based on the main water source device 21. For the embodiments generated by the main water source device 21, one is to install a main water tank 211 outside the fan head 1. In this embodiment, first, water is added to the main water tank 211 and the secondary water tank 22, and the sealing member 5 at the top is covered to make the secondary water tank 22 in a sealed state. When the product sprays, the atomizing device 4 sprays the water in the secondary water tank 22. After the water is sprayed by the atomizing device 4, a negative pressure area with a relatively small pressure is formed inside the secondary water tank 22. At this time, the main water tank 211 with a relatively large pressure will flow the water stored in it into the secondary water tank 22 with a relatively small pressure through the water pipe 3, resulting in a backflow phenomenon and forming negative pressure water absorption. At the same time, as long as there is still water in the secondary water tank 22, the main water tank 211 can be disassembled for water addition without interrupting the spraying; the second embodiment is to connect an adapter ring 212 outside the fan head 1 and an external drinking water bottle. In fact, the adapter ring 212 and the external drinking water bottle realize the replacement of the main water tank 211, so as to provide a water replenishment function for the secondary water tank 22. Since the structure is similar to the first embodiment, it will not be elaborated here.

[0046] It can be understood that during the actual production of the product, the main water tank 211 and the adapter ring 212 can be installed at the same time. And for the convenience of assembly and consumer use, the adapter ring 212 is set to a structure that is screwed with the main water tank 211. The shape of the docking position of the main water tank 211 can be designed to be the same as that of the commonly sold drinking water bottles on the market.

[0047] It should be noted that although the attached drawings in the present utility model are examples of handheld fans, the dual-water-tank design of the present utility model can be applied to various styles of spray fans, that is, negative pressure water absorption is generated through the main water source device 21 and the secondary water tank 22, and then rapid water replenishment operation is carried out without interrupting the spraying.

[0048] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
