Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a spray fan. Background Technology

[0002] Currently, existing misting fans are broadly divided into two categories: AC misting fans powered by mains electricity and DC misting fans powered by battery packs. AC misting fans are limited by the availability of power outlets, thus restricting their application scenarios. DC misting fans, due to the need for larger battery packs, are correspondingly larger and heavier. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention proposes a spray fan that has a wider range of applications and is small in size and lightweight.

[0004] To achieve the above objectives, the present invention provides a spray fan comprising:

[0005] A fan assembly, which includes fan blades and a motor for driving the fan blades to rotate;

[0006] Nozzles are used to spray water mist.

[0007] A water supply system comprising a water pipe assembly and a pump, wherein the water pipe assembly is connected to a nozzle and the pump is connected to the water pipe assembly for pumping water from a water source into the water pipe assembly.

[0008] The nozzle includes a nozzle body, a nozzle head, a water guide, and an elastic element. The nozzle head is detachably connected to the nozzle body. The water guide is movably disposed inside the nozzle via the elastic element. The outer peripheral wall of the water guide has a water guide groove extending along the central axis of the nozzle.

[0009] The pump supplies water to the nozzle at a water pressure of 100-200 PSI.

[0031] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0032] like Figure 1 and Figure 2 As shown, the preferred embodiment of the spray fan 100 of this utility model includes a fan assembly 1, a nozzle 2, and a water supply system 3. The fan assembly 1 includes fan blades 11 and a motor (not shown) for driving the fan blades to rotate; the motor is coaxially connected to the fan blades 11. The nozzle 2 is mounted on the fan assembly 1 and is used to spray water mist. The water supply system 3 includes a water pipe assembly (not shown) and a pump 30. The water pipe assembly is connected to the nozzle 2, and the pump 30 is connected to the water pipe assembly to pump water from a water source into the water pipe assembly, thereby pressurizing the water from the water source and delivering it to the nozzle 2.

[0033] The aforementioned "water source" includes both water stored in containers and external tap water.

[0034] Furthermore, the fan assembly 1 also includes a mesh cover 13, which is installed on the front side of the fan assembly 1 and serves as a safety protection. Preferably, the nozzle 2 is installed on the mesh cover 13.

[0035] like Figure 3 and Figure 4 As shown, the nozzle 2 includes a nozzle body 21, a nozzle head 22, a water guide 23, and an elastic member 24. The nozzle head 22 is detachably connected to the nozzle body 21. The water guide 23 is movably disposed inside the nozzle 2 via the elastic member 24. The outer peripheral wall of the water guide 23 has a water guide groove 230 extending along the central axis A of the nozzle 2.

[0036] One end 21a of the nozzle body 21 is connected to the water pipe assembly, and the other end 21b is detachably connected to the nozzle head 22. A sealing ring 25 is installed between the nozzle body 21 and the nozzle head 22.

[0037] The nozzle body 21 has a water flow channel 211 that communicates with the water pipe assembly. The interior of the nozzle body 21 forms a receiving cavity 212 that communicates with the water flow channel 211. The elastic member 24 and the water guide member 23 are housed in the receiving cavity 212, and the elastic member 24 is located at the bottom of the receiving cavity 212.

[0038] The nozzle head 22 has a nozzle hole 221, and an internal space 222 is formed inside the nozzle head 22. When the nozzle head 22 is connected to the nozzle body 21, the receiving cavity 212 communicates with the internal space 222, together forming an active space for the water guide 23 to move.

[0039] Multiple water guide grooves 230 opened on the outer peripheral wall of the water guide component 23 can guide the flow of high-pressure water entering the nozzle 2, so that the water flows evenly to the nozzle head 22, thereby reducing the probability of the nozzle head 2 being blocked by scale and impurities.

[0040] The nozzle head 22 is detachably connected to the nozzle body 21, allowing the user to remove the nozzle head 22 in case the nozzle 2 becomes clogged, and clean the scale and impurities inside the nozzle 2 to ensure that the nozzle 2 has a good spray effect. Preferably, in this embodiment, the nozzle head 22 is detachably connected to the nozzle body 21 via a threaded connection mechanism 26. In other embodiments, the nozzle head may also be connected to the nozzle body using other detachable connection structures.

[0041] In this invention, the spray fan 100 includes a plurality of nozzles 2, which are evenly distributed on the same circumference with the rotation center O of the fan assembly as the center.

[0042] exist Figure 1 and Figure 5a In the preferred embodiment shown, a plurality of nozzles 2 are evenly distributed on the circumference of the outer edge 15 of the fan assembly 1. Preferably, this embodiment includes three nozzles, with adjacent nozzles spaced 120° apart. The nozzle heads 22 of the nozzles 2 are inclined toward the center 10 of the fan assembly 1, so that the water mist sprayed by the nozzles 2 is substantially within the airflow range blown by the fan assembly 1, thereby utilizing the water mist more efficiently to cool the surrounding environment. Preferably, the angle at which the nozzle heads 22 are inclined toward the center 10 of the fan assembly 1 is not less than 30°.

[0043] like Figure 5b In the second embodiment shown, a plurality of nozzles 2 are evenly distributed on the circumference of the center 10 of the fan assembly 1. The nozzle heads 22 of the nozzles 2 are inclined toward the outer edge 15 of the fan assembly 1, so that the water mist sprayed by the nozzles 2 is within the airflow range blown by the fan assembly 1. Preferably, the angle at which the nozzle heads 22 are inclined toward the outer edge 15 of the fan assembly 1 is not less than 30°.

[0044] like Figure 5c In the third embodiment shown, a plurality of nozzles 2 are evenly distributed on a circumference between the center 10 and the outer edge 15 of the fan assembly 1. In this embodiment, the central axis of the nozzles 2 is substantially parallel to the central axis of the fan assembly 1.

[0045] The “center” of the aforementioned fan assembly 1 refers to the middle part of the fan blades or the mesh cover, specifically, the part of the fan blades that extends outward from it, or the part of the mesh cover that extends outward from it.

[0046] This invention does not limit the number of nozzles; those skilled in the art can select an appropriate number of nozzles according to actual needs.

[0047] like Figure 1 and Figure 2 As shown, the spray fan 100 also includes a baffle ring 4, which is disposed around the periphery of the fan assembly 1, forming an airflow channel 40 between the baffle ring 4 and the fan assembly 1. Specifically, the baffle ring 4 includes a first part 41 and a second part 42. The first part 41 is located outside the outer circumferential wall 14 of the fan assembly 1 and is connected to the fan assembly 1. Preferably, in this embodiment, the first part 41 is connected to the outer circumferential wall 14 by a rib 5. In other embodiments, the first part 41 can also be connected to the fan assembly 1 by other structures and can be connected to other parts of the fan assembly 1. This utility model does not limit the connection position and connection structure. The second part 42 is connected to the front side of the first part 41 and extends obliquely from the front side toward the external space to form a trumpet-shaped opening. Furthermore, in the direction of the central axis of the fan assembly 1, the second part 42 at least partially extends beyond the fan assembly 1, thereby extending the length of the airflow channel 40.

[0048] The inner surface of the baffle ring 4 is at a certain distance from the outer circumferential wall 14 of the fan assembly 1, and the space between them forms an airflow channel 40. The baffle ring 4 allows air behind the fan assembly 1 to enter the periphery of the fan assembly 1, increasing the airflow around the fan assembly 1. This means that the air blown by the spray fan of this invention includes not only the main airflow generated by the fan assembly 1 itself, but also the airflow around the fan assembly 1. Therefore, the spray fan can blow out a larger and stronger airflow. The airflow becomes more concentrated after passing through the airflow channel 40, and under the guidance of the second part 42, the airflow is blown to a larger area, achieving cooling of a larger area.

[0049] In other embodiments, LED lights (not shown) are mounted on the retaining ring 4 to enhance the ambiance.

[0050] In this invention, the pump 30 supplies water to the nozzle 2 at a water pressure of 100 to 200 PSI, and the diameter of the nozzle orifice 221 of the nozzle head 22 is no greater than 0.4 mm. Based on this setting, the water mist sprayed from the nozzle 2 is finer and more uniform.

[0051] The spray fan 100 of this utility model includes a built-in battery (not shown), which makes the application scenarios of the spray fan 100 more extensive, and its size and weight are smaller, making it more convenient to use.

[0052] exist Figure 1 In the illustrated embodiment, the spray fan 100 is a floor-standing type, comprising a base 6, a support rod 7, a control unit 8, and a fan bracket 9. The base 6 is used to place the spray fan 100 on the ground. The lower end of the support rod 7 is connected to the base 6, and the upper end is connected to the control unit 8. The top of the control unit 8 is connected to the fan bracket 9, which is approximately U-shaped and used to support the fan assembly 1. The outer casing of the control unit 8 is provided with an operation panel 80 with operation buttons for user operation. The pump 30 is mounted on the control unit 8, and a built-in battery is installed inside the control unit 8. The control unit 8 also contains a control board (not shown) for controlling the operation of the spray fan 100.

[0053] Figure 1 The illustration shows one form of the spray fan of this utility model. In other optional embodiments, the spray fan may also take other forms, such as tabletop, wall-mounted, etc.

[0054] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
