The signal reception mode of the existing RV fans is set in advance and cannot be adjusted arbitrarily once set. As a result, when multiple fans are installed, only one remote control can control multiple fans at the same time, increasing costs and wasting energy when not necessary. Summary of the Utility Model
[0006] In order to facilitate the adjustment of the signal reception mode of the RV fan, so that one remote control can control multiple fans simultaneously or can separately control one or more of them, the utility model provides an RV fan and an RV.
[0007] First aspect: The utility model provides an RV fan, adopting the following technical scheme:
[0008] An RV fan includes a lower box main body, a blowing component for blowing air, a position adjustment component for adjusting the blowing direction of the blowing component, and a control component for controlling the operation of the blowing component;
[0009] The control component includes a circuit board, a signal receiver, a signal selector, and a remote control. The circuit board, the signal receiver, and the signal selector are all fixedly installed on the lower box body. The signal receiver, the signal selector, and the circuit board are electrically connected in sequence. Multiple signal transmission modules are provided on the remote control, and all of the multiple signal transmission modules are wirelessly connected to the signal receiver.
[0010] By adopting this technical solution, the remote control emits a control signal, and the signal receiver on the control component can receive the control signal emitted by the remote control and transmit the signal to the circuit board to control the blowing component to work. When there are multiple fan bodies, the signal selector on each fan body can be set separately, so that the signal receiver on each fan body can receive signals of different modes. Then, multiple signals corresponding to the received modes of the multiple signal receivers are emitted through the signal transmission modules of different modes on the remote control, realizing the individual control of multiple fans by one remote control. It is possible to specifically turn on the fans that need to work without controlling other fans, saving energy when not necessary.
[0011] Optionally, a power interface is provided on the lower box body, and the control component is electrically connected to the power interface.
[0012] By adopting this technical solution, a power interface is provided on the lower box body to directly supply power to the fan, reducing the manufacturing cost. At the same time, when it is inconvenient to directly supply power with a DC power supply, an internal battery can be installed inside the lower box body, and connecting the internal battery to the power interface can charge the internal battery, expanding the usage scenarios.
[0013] Optionally, a first fixing plate is fixedly installed on the side wall inside the lower box body, and the power interface is fixedly installed on the first fixing plate.
[0014] By adopting this technical solution, the first fixing plate can increase the fixing area between the power interface and the lower box body, making the power interface more firmly fixed.
[0015] Optionally, the signal selector includes a rotary encoder switch. The rotary encoder switch is fixedly installed on the lower box body and is electrically connected to the circuit board. By changing the position of the rotary encoder switch, the signal receiving mode of the signal receiver can be adjusted.
[0016] By adopting this technical solution, the circuit board controls the signal receiver to receive signals of different modes according to the digital information output by the rotary encoder switch. In this way, the function of signal selection can be realized by inputting different control signals to control the rotary encoder switch.
[0017] Optionally, the signal selector further includes a dedicated knob, which is connected to the knob coding switch in a cooperative manner.
[0018] By adopting this technical solution, when the dedicated knob is rotated, the knob coding switch will collect the position information of the dedicated knob and output different digital signals according to different position information of the dedicated knob. The setting of the dedicated knob facilitates the control of the knob coding switch and simplifies the operation of signal selection.
[0019] Optionally, a second fixing plate is further fixedly installed on the inner side wall of the lower box body, and the knob coding switch is fixedly installed on the second fixing plate.
[0020] By adopting this technical solution, the second fixing plate can increase the fixing area between the knob coding switch and the lower box body, make the knob coding switch more firmly fixed, reduce the probability of being damaged, and increase the service life.
[0021] Optionally, each signal transmitting module on the remote controller includes a timing adjustment module and a wind speed adjustment module.
[0022] By adopting this technical solution, when adjusting different fans, the timing adjustment module and the wind speed adjustment module can be directly used through the signal transmitting module corresponding to the fan to adjust the wind speed and timing of the fan. Each button corresponds to the function of a different fan, and there is no need to adjust multiple buttons on the remote controller, making the operation simpler.
[0023] Optionally, the lower box body is further provided with a plurality of wind speed adjustment indicator lights and a plurality of timing adjustment indicator lights that are all electrically connected to the circuit board.
[0024] By adopting this technical solution, the wind speed adjustment indicator lights and the timing adjustment indicator lights can provide signal feedback for users when the fan is controlled remotely by the remote controller at a long distance, enabling users to clearly know the current working state of the fan without approaching the fan body, which is convenient for users to adjust and control.
[0025] Optionally, the lower box body is further provided with a lower box cover plate and a fan base. The lower box cover plate is connected to the lower box body. The circuit board is fixedly installed on the lower box cover plate. The lower box cover plate is provided with a special-shaped sliding groove with different opening diameters at both ends. The fan base is provided with a special-shaped column, and the special-shaped column is provided with a groove with a diameter between the opening diameters of both ends of the special-shaped sliding groove. The fan base is slidably arranged in the special-shaped sliding groove of the lower box cover plate through the special-shaped column.
[0026] By adopting this technical solution, during installation, the fan base can be first fixed on the wall, and then the lower box body fixedly connected to the lower box cover plate can be slidably installed on the fan base. When installing, the end with a larger opening of the special-shaped chute is oriented away from the ground, so that the special-shaped chute is installed at the groove on the special-shaped column. Moving the special-shaped chute towards the end with a smaller opening can snap the groove on the special-shaped column into the special-shaped chute. After fixing the fan base in this way, when disassembling and assembling the fan again, only need to slide the fan body to remove or install the special-shaped chute from the special-shaped column, and the installation is convenient and fast.

Through the above method, the fan can rotate 360° through damping connection positions.
[0048] Refer to Figures 4 to 6, the lower box body 300 includes a power interface 310, a rotating shaft 320, a locking assembly 330, a first fixing plate 340, a second fixing plate 350, a timing button 360, a wind speed adjustment button 370, a lower box cover 380, and a fan base 390. A rotating shaft 320 is rotatably connected to the upper part of the lower box body 300. The rotating shaft 320 is connected to the bottom ring sleeve 221 of the fan main frame 220 and is axially limited by the baffle of the lower box body 300. The pin holes of one side of the ring sleeve 221 are slidably connected to the lock catch assembly to achieve limitation.

The power interface 310 is a DC socket plug, and the DC socket plug is fixedly installed in the hole position on the second fixing plate 350. The power interface 310 is a basic power supply method. In the case where it is inconvenient to directly use the power interface 310 for power supply, an internal power supply can be connected inside the lower box body 300. The power interface 310 is connected to the internal power supply and charges the internal power supply. The timing button 360 and the wind speed adjustment button 370 are fixedly installed through the corresponding holes on the lower box body 300.

A groove is provided at the middle position of the special-shaped column 391, and the diameter of the groove is the same as the diameter of the smaller opening of the special-shaped chute 381. The groove of the special-shaped column 391 of the fan base 390 is slidably connected to the special-shaped chute 381 of the lower box cover 380 to achieve the overall installation of the lower box.
[0049] Refer to Figures 6 to 10, the control component 400 includes a circuit board 430, a signal receiver 420, a signal selector 410, and a remote controller 440. The signal selector 410 can select the received signal by controlling the receiving antenna, adjusting the RF front-end processing module, or by adjusting the digital signal processing module. In this embodiment, taking the control of the digital signal processing module by a rotary encoder as an example, in other embodiments, methods such as frequency modulation, amplitude modulation, or adjusting the carrier wave can be used to achieve the selection of the received signal. The signal selector 410 includes a dedicated knob 411 and a knob coding switch 412. The dedicated knob 410 is a simple way to control the knob coding switch 412 to switch modes. In other embodiments, the knob coding switch 412 can also be controlled to rotate by using a handle or a dial. The knob coding switch 412 is installed at the corresponding position on the first fixing plate 340 and connected to the circuit board 430 through a wire. Then, the dedicated knob 411 is fixedly installed at one end of the knob coding switch 412 facing the outside of the lower box body 300. Finally, the circuit board 430 is connected to the lower box body 300, and the circuit of the circuit board 430 passes through the lower box cover 380 and is fixed. The remote controller 440 includes five signal transmitting modules. Each signal transmitting module includes a control button for an infrared emitter, a timing adjustment module 441, and a wind speed adjustment module 442. The remote controller 440 can emit infrared signals of five modes by using the infrared emitters in the five signal transmitting modules. The infrared emitter can control the infrared emitter to emit different types or modes of control signals by adjusting the intensity, frequency of the infrared ray, or by modulating the carrier wave, etc. In this embodiment, the different modes of infrared signals described refer to controlling the infrared emitter to emit different control signals by adjusting the frequency of the infrared ray. In other embodiments, controlling the infrared emitter to emit different mode control signals by adjusting the intensity of the infrared ray or modulating the carrier wave, etc. is also possible. Among them, the knob coding switch 412 correspondingly has five modes. Each mode controls the signal receiver 420 to receive a mode signal emitted by a certain group of signal transmitting modules on the corresponding remote controller 440. For example, by operating the dedicated knob 411 to adjust the knob coding switch 412 of a certain fan to mode one, the circuit board 430 only receives the signal emitted by the infrared emitter in the signal transmitting module 1 of the remote controller 440 according to the setting. By operating the wind speed adjustment module 442 or the timing adjustment module 441 of the signal transmitting module 1 of the remote controller 440, the small fan can be controlled to complete the corresponding wind speed adjustment or timing adjustment operation. At this time, the wind speed or timing adjustment modules of other signal transmitting modules on the remote controller 440 cannot control this fan, so as to realize the control of the knob coding switch 412 of the fan in the same mode by a group of signal transmitting modules of the remote controller 440.
[0050] The specific implementation principle of a motorhome in an embodiment of the present utility model is as follows: When using the remote control 440 to control multiple motorhome fans jointly: By rotating the dedicated knobs 411 on different motorhome fans, the knob coding switches 412 on multiple motorhome fans are adjusted to the same mode. At this time, the signal receivers 420 on different motorhome fans can receive signals of the same mode, and multiple motorhome fans can be controlled simultaneously by pressing the buttons on the corresponding signal transmission module of the remote control 440; When using the remote control 440 to control different motorhome fans individually: By rotating the dedicated knobs 411 on different motorhome fans, the knob coding switches 412 on different motorhome fans are adjusted to different modes, and the motorhome fan with the knob coding switch 412 set to the corresponding mode can be controlled by pressing the buttons on the corresponding signal transmission module of the remote control 440, realizing the individual control of different motorhome fans. When using the remote control 440 to adjust the rotation speed or timing of the motorhome fan, reference can also be made to the timing adjustment indicator light 361 and the wind speed adjustment indicator light 371 on the motorhome fan, and the working state of the motorhome fan can be adjusted more intuitively.
[0051] In summary, in the embodiment of the present utility model, a signal receiver 420 and a signal selector 410 are installed on the motorhome fan, so that the motorhome fan can receive signals of different modes by adjusting the signal selector 410, and the remote control 440 is designed so that it can emit signals of different modes. By adjusting the signal selectors 410 on multiple motorhome fans to receive signals of the same mode, the simultaneous control of multiple motorhome fans can be achieved; By adjusting the signal selectors 410 on multiple motorhome fans to receive signals of different modes, the individual control of different motorhome fans can be achieved; The signal selector 410 is made of a dedicated knob 411 and a knob coding switch 412, enabling users to adjust the signal receiver 420 by rotating the dedicated knob 411 and the knob coding switch 412, which is convenient for users to operate. For example, the knob coding switch 412 includes five modes from 1 to 5, and the signal receiving mode is infrared; The wind speed adjustment indicator light 371 and the timing adjustment indicator light 361 are set to provide users with information feedback when controlling the motorhome fan through the remote control 440, clarify the working state of the motorhome fan, and facilitate users to adjust according to the working state of the motorhome fan.
[0052] The above is the preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
