Description

Technical Field

[0001] The present invention relates to a fan, and more particularly to a fan with a fast switching usage mode. Background Art

[0002] A fan is a common electrical appliance that uses an electric motor to drive the fan blades to rotate to accelerate the air circulation. Installing a fan in a recreational vehicle can cool off and promote air circulation, improving people's living comfort.

[0003] In a Chinese utility model patent application with the application number 2024221261848 and the title "A Recreational Vehicle Fan and a Recreational Vehicle" (not yet published as of May 21, 2025), a fan applied to a recreational vehicle is provided. It includes a lower box body for fixed connection and a blowing assembly. The blowing assembly is connected to the lower box body through a position adjustment assembly, and this position adjustment assembly is used to adjust the blowing direction of the blowing assembly. The lower box body is fixedly installed inside the carriage. This fan needs to be fixed at a preset position inside the vehicle, resulting in limited usage range and unable to meet the needs of position changes.

[0004] In a Chinese utility model patent with the application number 2023218034280 and the title "A Fan with a Quick - detachable Battery Pack", a fan that can be used movably is disclosed. It includes a fan body, a connection base is provided at the lower part of the fan body, a battery pack is detachably connected below the connection base, several conductive contacts are provided at the rear of the connection base, and several conductive card slots corresponding to the conductive contacts are provided on the battery pack for connection with the conductive contacts. It has a quick - detachable battery pack below the fan for power supply to the fan, with the characteristics of being used anywhere and movably. However, due to the limited power stored in the battery pack, it can only be used for a short time in a scenario without wiring. If it is necessary to meet the daily continuous usage requirements in a recreational vehicle, the battery pack needs to be replaced frequently, and the fan cannot be reliably fixed, bringing inconvenience to use, especially not suitable for bumpy spaces.

[0005] In the prior art, there are also fans that can be switched between mobile and fixed usage modes. They can be powered by a detachable battery pack, thus facilitating position adjustment for use at any time. When the battery pack is removed, it can also be plugged in and used through a fixed power source. However, when it is plugged in and used, the position of the fan can only be placed in a certain area and cannot be reliably fixed to the surrounding environment. Therefore, it cannot adapt to the working conditions of a recreational vehicle during movement and bumpy states. Summary of the Invention

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the embodiments.

[0033] A fan with a quick-switch mode of use includes a fan body and an adapter assembly 600. The fan body includes a blowing assembly, a control assembly 430 for controlling the operation of the blowing assembly, and a lower box body. The blowing assembly and the control assembly 430 are both arranged on the lower box body. The lower box body is electrically connected to the control assembly 430, and the lower box body is detachably connected to the adapter assembly 600. The adapter assembly 600 is used to electrically connect the lower box body to the power supply module. Among them, the blowing assembly is the same as the utility model patent application "Application No. 2024221261848, entitled "A RV Fan and RV", and the specific structure and connection method will not be repeated here. Figure 1 It is a schematic diagram of the overall structure of the cited patent application.

[0034] like Figures 2-5As shown in the figure, the lower box body includes a lower box housing 300 and a lower box cover plate 380 provided below the lower box housing 300. The lower box cover plate 380 is connected to the lower box housing 300 by screws. A connection port 381 is provided at the lower part of the lower box cover plate 380, and a number of conductive posts 382 are provided in the connection port 381. The conductive posts 382 pass through the lower box cover plate 380 and are electrically connected to the control component 430 through control wires. To standardize the wiring, a section of the control wire close to the lower box cover plate 380 is a plastic-coated plate-like structure. One end of it is provided with a wiring pin connected to the power pin of the control component 430, and the other end is connected to the conductive post 382.

[0035] As Figure 6 , Figure 7 , Figure 9 As shown in the figure, the adapter component 600 includes an adapter base 610 and an adapter bottom plate 620. A connection platform 611 adapted to the connection port 381 is provided at the upper part of the adapter base 610. A card slot 612 corresponding to the conductive post 382 is provided on the connection platform 611. A wiring cavity 613 is provided at the lower part of the connection platform 611 corresponding to the card slot 612. A conductive clip 614 is arranged in the corresponding card slot 612, and one end of it extends into the wiring cavity 613.

[0036] As Figures 4-5 As shown in the figure, guide grooves 383 are provided on the two side walls of the connection port 381 in the horizontal direction. Guide bars 615 are provided on the two sides of the connection platform 611. The guide bars 615 can slide along the corresponding guide grooves 383. The connection platform 611 slides into the connection port 381 along with the guide bars 615 until the conductive clip 614 on the connection platform 611 is docked with the conductive post 382. The connection platform 611 can also slide out of the connection port 381 along with the guide bars 615 to disconnect the conductive clip 614 from the conductive post 382 until the adapter base 610 is separated from the lower box cover plate 380.

[0037] To realize the limit of the adapter base 610 and the lower box cover plate 380, a limit port 384 is provided on the connection port 381 of the lower box cover plate 380, and a through hole 616 corresponding to the limit port 384 is provided on the connection platform 611 of the adapter base 610. A limit mechanism 617 is provided on the adapter base 610. As Figure 8As shown, the limiting mechanism 617 includes a limiting slider 6171, a limiting tongue 6172, a limiting pressure plate 6173 and a limiting spring 6174. Among them, the limiting slider 6171, the limiting tongue 6172 and the limiting pressure plate 6173 are integrally arranged. The limiting tongue 6172 and the limiting pressure plate 6173 are respectively arranged at both ends of the limiting slider 6171. The limiting pressure plate 6173 extends from one side of the adapter base 610 for pressing. A limiting chute 618 is vertically opened on the adapter base 610. The limiting slider 6171 slides along the guidance of the limiting chute 618 to drive the limiting tongue 6172 to extend out or retract from the through hole 616, so as to cooperate with the limiting port 384 to lock or unlock. When the limiting pressure plate 6173 is not pressed, the limiting spring 6174 is supported between the limiting slider 6171 and the adapter bottom plate 620. A limiting blind hole 622 is provided on the adapter bottom plate 620. One end of the limiting spring 6174 is arranged in the limiting blind hole 622, and the other end is connected to the bottom of the limiting slider 6171, which is used to keep the limiting tongue 6172 in the limiting position. When pressing the limiting pressure plate 6173, the whole formed by the limiting slider 6171, the limiting tongue 6172 and the limiting pressure plate 6173 slides downward, and the limiting spring 6174 is compressed, so that the limiting tongue 6172 disengages from the limiting port 384 to unlock. The adapter bottom plate 620 is horizontally attached to the bottom of the adapter base 610, which keeps the limiting slider 6171 in the limiting chute 618. The adapter bottom plate 620 also covers the wiring cavity 613 at the same time. A wiring hole 621 communicating with the wiring cavity 613 is provided on the adapter bottom plate 620.

[0038] The power supply module includes a fixed power supply module and a mobile power supply module. There are at least two adapter assemblies 600. Among them, at least one adapter assembly 600 is installed at a fixed position in the space and is electrically connected to the fixed power supply module, and at least one adapter assembly 600 is electrically connected to the mobile power supply module.

[0039] When the fan uses the fixed power supply module, as Figure 6 shown, connect the wire led out by the conductive clip 614 through the wiring cavity 613 and the wiring hole 621 to the reserved power cord in the carriage 500, and then fix the adapter assembly 600 on the carriage 500. Align the connection port 381 of the lower box cover plate 380 of the fan with the connection platform 611 and slide the guide groove 383 along the guide bar 615. Press down the lower box cover plate 380 to compress the limiting spring 6174, and the limiting tongue 6172 retracts into the through hole 616. Until the conductive column 382 is in full contact with the conductive clip 614, the limiting tongue 6172 extends out of the through hole 616 and extends into the limiting port 384 under the elastic action of the limiting spring 6174 to complete the limiting of the adapter base 610 and the lower box cover plate 380. At this time, the fan motor is connected to the reserved power cord in the carriage 500 through the control component 430, the conductive column 382 and the conductive clip 614, realizing the continuous use of the fan at the preset position in the carriage 500.

[0040] At this time, since the adapter assembly 600 is fixed on the car body 500, its spatial position relative to the car body is fixed. Therefore, after the fan body is slidably installed on the adapter assembly 600, its spatial position relative to the car body is also relatively fixed, ensuring the stability of the vehicle during bumpy use.

[0041] When the fan is using the mobile power module 700, Figure 7 As shown, the mobile power module is located below the adapter assembly 600 and includes a battery box 710 and a battery 720, with the battery 720 located within the battery box 710. During use, the battery box 710 is fixed to the adapter base plate 620 of the adapter assembly 600. Wires extending from the conductive clip 614 through the wiring cavity 613 and the wiring hole 621 are connected to the battery 720, providing a portable power source for the fan.

[0042] To switch the fan from fixed to mobile mode, the limiting pressure plate 6173 is pressed, causing the limiting tongue 6172 to retract into the through hole 616. The fan is then slid, disengaging the fan's lower cover 380 from the adapter assembly 600 fixed to the vehicle compartment 500. The fan's lower cover 380 is then connected to the adapter assembly 600 in the mobile power module 700 until the conductive posts 382 and conductive clips 614 are fully engaged and the limiting mechanism 617 has fully secured the adapter 610 and lower cover 380. At this point, the fan's control assembly 430, conductive posts 382, and conductive clips 614 are connected to the battery 720. Powered by the battery 720, the fan is no longer restricted by the location of an onboard power source, allowing it to be used anytime, anywhere.

[0043] In addition, to quickly understand the power level of the battery 720, a power display module 711 connected to the battery 720 is provided on the battery box 710. A charge and discharge interface 712 connected to the battery 720 is provided on the battery box 710. The battery 720 can be charged in a timely manner according to the displayed power level, or the battery 720 can be used as a power source for other devices. The lower box body of the fan is provided with a lighting lamp 391 and a lighting adjustment button 392 for controlling the lighting lamp 391 to turn on and off. The lighting lamp 391 is connected to the control component 430 in a conventional manner via the lighting adjustment button 392, extending the use of the fan. Compared with the utility model patent application "Application No. 2024221261848, entitled "A RV Fan and RV", the control component in this application has added a power pin electrically connected to the lighting adjustment button 392. Both are conventional structures, and the specific structure and connection method are not repeated here.

[0044] In the present application, when the adapter component 600 is fixed, the lower box body and the blowing component can be easily removed, moved to other locations and installed on another set of adapter components 600 and mobile power module 700, thereby realizing the conversion of the fan from fixed installation to mobile installation, and vice versa. The fixed installation mode can provide a long-lasting power supply, and the mobile installation mode can meet the usage requirements of different locations. The rapid conversion between the two modes avoids the position limitation brought by fixed installation, and also avoids the trouble of replacing batteries caused by battery capacity, thereby solving the problems existing in the prior art.

[0045] However, the above description is merely a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the present invention should still fall within the scope of the claims of the present invention.
