[0009] By adopting the above technical solution, after several fans are installed on the mounting plate, the mounting plate is inserted into the insertion opening together with the fans. The reverse guide rail is inserted into the forward guide rail and slides along the forward guide rail. During the sliding process, the several fans enter the box body until the mounting plate closes the insertion opening. The locking mechanism locks the reverse guide rail to fix the positions of the several fans. When maintenance is required, the locking mechanism is used to unlock the reverse guide rail, and the mounting plate can be pulled to take out the several fans from the insertion opening, so as to achieve the effect of facilitating maintenance.

[0010] Optionally, the mounting plate is divided into two layers. The size of the first-layer plate body is larger than that of the insertion opening, and the size of the second-layer plate body is equal to that of the insertion opening. When the second-layer plate body is inserted into the insertion opening, the first-layer plate body covers the insertion opening.

[0011] By adopting the above technical solution, since the size of the second-layer plate body is equal to that of the insertion opening, the second-layer plate body can block the insertion opening, and then the first-layer plate body with a size larger than that of the insertion opening is used to cover the insertion opening, so as to achieve the effect of closing the insertion opening and reduce the air leakage from the insertion opening.

[0012] Optionally, a sealing layer is provided between the first-layer plate body and the second-layer plate body, and the sealing layer contacts the box body beside the insertion opening.

[0017] By adopting the above technical solution, the locking rod is provided with an external thread through the connection point between the first section and the second section, and the third section is provided with an external thread at the end away from the first section, so that the two sections of external threads are screwed to the first threaded hole and the second threaded hole respectively when locking. The two-point screw connection provides stable stability. During the unlocking or insertion process, the second section without external threads is used to directly penetrate the first locking port and the second locking port, thereby improving the convenience of locking without the need to rotate too many turns, thereby improving the convenience of locking or unlocking.

[0018] Optionally, the first locking openings are provided with two groups, which are respectively located at an end of the reverse guide rail close to the mounting plate and an end away from the mounting plate.

[0019] By adopting the above technical solution, when the locking rod locks the reverse guide rail near the first locking opening at one end of the mounting plate, the fan assembly is in a closed state and can operate normally; when the locking rod disengages from the first locking opening and the second locking opening, the reverse guide rail can move along the forward guide rail, and during the movement, the first locking opening away from one end of the mounting plate is docked with the second locking opening, and then the locking rod is inserted for locking, so that several fans will not be separated from the embedded opening and the box body. This method enables several fans to be repaired and cleaned without being disassembled from the box body or the embedded opening, eliminating the disassembly and assembly process and improving the efficiency of maintenance or cleaning.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. After the battery pack conveys power to the fan assembly, the fan assembly forms an air flow and conveys it to the air outlet grille, and the outdoor environment is cooled through the air outlet grille.

In addition, when it is said that a certain device "includes" a certain component, unless there is a particularly contrary record, it does not exclude other components, but means that other components can also be included.

[0044] The following combines the attached Figure 1 - attached Figure 7 , and further details the present application.

[0045] The embodiment of the present application discloses an outdoor fan.

[0046] An outdoor fan, referring to Figure 1 and Figure 2As shown in the figure, it includes a box body 1. The box body 1 provides installation and protection. The interior of the box body 1 is an installation space, and there are several mounting brackets 10 for fixing and supporting, providing the fixing and installation of other components.

[0047] Inside the box body 1, there are a locking mechanism 2, a fan assembly 3, an air outlet grille 4, a battery pack 5 and an inverter; the air outlet grille 4 is embedded at one end of the box body 1, and the air outlet grille 4 can also be provided with a control switch and an adjustment switch, which are used to adjust and control the overall opening and closing of the outdoor fan. The air outlet grille 4 provides the air outlet of the outdoor fan. The air outlet grille 4 is aligned with the user to achieve the effect of air cooling, accelerating the air flow speed of the surrounding environment, so as to provide the function of adjusting the environmental temperature.

[0048] Among them, if it is necessary to further provide a cooling effect, a refrigeration structure such as a compressor can be set to further achieve the cooling effect.

[0049] The fan assembly 3 is slidably connected to the other end of the box body 1. The fan assembly 3 is the main tool for providing the change of the environmental gas flow speed. During the outdoor use of the fan assembly 3, it is easy to draw in too much dust, dry grass, branches, leaves and other sundries, resulting in easy dust collection or accumulation of sundries inside the fan. If not cleaned for a long time, it is easy to be damaged. Therefore, by slidingly connecting the fan assembly 3 to one end of the box body 1, it can be easily slid out from one end of the box body 1, facilitating maintenance or cleaning.

[0050] The battery pack 5 is installed on the mounting bracket 10. The battery pack 5 provides power supply. The battery pack 5 is also connected to an inverter, which provides the conversion of the direct current of the battery pack 5 into alternating current to ensure that the fan assembly 3 can stably obtain the power supply of alternating current.

[0051] The locking mechanism 2 is installed on the side wall of the box body 1 and is clamped with the fan assembly 3, providing a locking effect on the fan assembly 3. The locking mechanism 2 is used for fixing the fan assembly 3, so that the fan assembly 3 will not slide out of the box body 1 at will. After the locking mechanism 2 finishes the locking effect, the fan assembly 3 loses the fixing effect and can be taken out of the box body 1 to achieve the effect of convenient maintenance.

[0052] Specifically, after the battery pack 5 delivers power to the fan assembly 3, the fan assembly 3 forms an air flow and delivers it to the air outlet grille 4. The outdoor environment is cooled down through the air outlet grille 4. When disassembly is required, the locking mechanism 2 is opened. After the locking mechanism 2 is disconnected from the fan assembly 3, the fan assembly 3 slides along the box body 1, so as to partially disengage from the box body 1, and then the fan assembly 3 can be repaired or cleaned to achieve the effect of convenient maintenance.

[0053] Further, refer to Figure 3As shown in the figure, the fan assembly 3 includes a mounting plate 31, a ventilation duct 32, and a plurality of fans 33; an embedding opening 11 is formed on the box body 1, and the mounting plate 31 is snap-connected to the embedding opening 11, so that the mounting plate 31 covers the embedding opening 11, making the appearance beautiful.

[0054] A plurality of fans 33 are installed on the mounting plate 31 and are bolted to the mounting plate 31. In this embodiment, the number of the plurality of fans 33 is three, which can be referred to in the figure.

[0055] A forward guide rail 12 is provided inside the box body 1, and a reverse guide rail 34 is provided on one side of the mounting plate 31 close to the box body 1. The reverse guide rail 34 is slidably connected to the forward guide rail 12. An inner groove is provided on the forward guide rail 12, and a guide protrusion is provided on the reverse guide rail 34. The guide protrusion is embedded in the inner groove and can move along the inner groove. The styles of the guide protrusion and the inner groove are the same, and can be T-shaped or arc-shaped to ensure that the reverse guide rail 34 cannot be separated from the forward guide rail 12, but can slide along the forward guide rail 12.

[0056] One end of the plurality of fans 33 away from the mounting plate 31 is connected to a ventilation duct 32, and the ventilation duct 32 communicates with the air outlet grille 4. The ventilation duct 32 is used to transport the air flow provided by the plurality of fans 33 to ensure the stability of wind cooling. The ventilation duct 32 can be a rectangular duct or a circular duct, and preferably a circular duct. The figure takes a rectangular duct as an example.

[0057] The reverse guide rail 34 is connected to the locking mechanism 2. After the reverse guide rail 34 is inserted into the forward guide rail 12 and moves along the forward guide rail 12 to the locking mechanism 2, the reverse guide rail 34 can be fixed by the locking mechanism 2, so that the reverse guide rail 34 cannot continue to move along the forward guide rail 12, so as to achieve the locking effect.

[0058] Specifically, after the plurality of fans 33 are installed on the mounting plate 31, the mounting plate 31 is inserted into the embedding opening 11, the reverse guide rail 34 is inserted into the forward guide rail 12 and slides along the forward guide rail 12. During the sliding process, the plurality of fans 33 enter the box body 1 until the mounting plate 31 closes the embedding opening 11, and the locking mechanism 2 locks the reverse guide rail 34 to fix the positions of the plurality of fans 33. When maintenance is required, the locking mechanism 2 is used to unlock the reverse guide rail 34, and the mounting plate 31 is pulled to take out the plurality of fans 33 from the embedding opening 11, so as to achieve the effect of facilitating maintenance.

[0059] In some embodiments, refer to Figure 4As shown, the mounting plate 31 is divided into two layers of plate bodies. The size of the first layer of plate body 311 is larger than that of the embedding opening 11, so that the first layer of plate body 311 can completely cover the embedding opening 11. The size of the second layer of plate body 312 is equal to or smaller than that of the embedding opening 11, so that the second layer of plate body 312 can be directly embedded into the embedding opening 11, while the first layer of plate body 311 covers the embedding opening 11, thus completing the closing effect, ensuring aesthetics and improving the sealing performance at the same time.

[0060] Specifically, since the size of the second layer of plate body 312 is equal to that of the embedding opening 11, the second layer of plate body 312 can block the embedding opening 11. Then, the first layer of plate body 311 with a size larger than that of the embedding opening 11 is used to cover the embedding opening 11, so as to achieve the function of closing the embedding opening 11 and reduce the air leakage from the embedding opening 11.

[0061] Furthermore, a sealing layer 3112 is provided between the first layer of plate body 311 and the second layer of plate body 312. The sealing layer 3112 contacts the box body 1 beside the embedding opening 11. The sealing layer 3112 can be made of a rubber layer. When the first layer of plate body 311 covers the embedding opening 11, the sealing layer 3112 is tightly attached to or pressed against the box body 1, thereby further improving the sealing performance and avoiding air leakage.

[0062] In some embodiments, referring to Figure 5 As shown, there are four groups of forward guide rails 12 and four groups of reverse guide rails 34. The mounting plate 31 is a rectangular plate. Therefore, the mounting plate 31 has four corners. The four groups of reverse guide rails 34 are respectively located at the four corners of the mounting plate 31, and the four groups of forward guide rails 12 are respectively located at the four corners of the embedding opening 11, so that the four groups of reverse guide rails 34 can just be embedded into the four groups of forward guide rails 12.

[0063] Setting four groups of forward guide rails 12 and reverse guide rails 34 can improve the installation stability of the overall mounting plate 31 and several fans 33. Using the four groups of reverse guide rails 34 makes the moving stability better, the moving position will not shift, and the connection is more stable.

[0064] In some embodiments, referring to Figure 5 As shown, the locking mechanism 2 includes a locking seat 21 and a locking rod 22; the locking seat 21 is installed on the box body 1, specifically, it can be installed on the mounting frame 10 inside the box body 1 and is located beside the reverse guide rail 34. The locking seat 21 is in the shape of a rectangular block and is connected to the inner wall of the box body 1. Reinforcing plates can be provided to improve the connection stability of the locking seat 21.

[0065] A first locking opening 341 is formed on the reverse guide rail 34, and a second locking opening 121 is formed on the forward guide rail 12. The diameters of the first locking opening 341 and the second locking opening 121 are the same. The diameter of the locking rod 22 is less than or equal to the diameters of the first locking opening 341 and the second locking opening 121, so that the locking rod 22 can just be inserted into the first locking opening 341 and the second locking opening 121.

[0066] The first threaded hole 13 is provided on the box body 1, and the second threaded hole 211 is provided on the locking seat 21. The apertures of the first threaded hole 13 and the second threaded hole 211 are the same, and the diameter of the locking rod 22 is less than or equal to the apertures of the first threaded hole 13 and the second threaded hole 211, so that the locking rod 22 can also just be inserted into the first threaded hole 13 and the second threaded hole 211. The axes of the first threaded hole 13, the second locking port 121 and the second threaded hole 211 are on the same horizontal axis, that is, they can communicate with each other.

[0067] When the locking rod 22 passes through the first threaded hole 13 in sequence and then through the first locking port 341, the second locking port 121 and the second threaded hole 211, the reverse guide rail 34 is fixed to the locking seat 21 and the forward guide rail 12, thereby fixing the positions of the mounting plate 31 and several fans 33.

[0068] Reference Figure 5 As shown, the locking rod 22 is divided into three sections. The first section is located outside the box body 1. A rotating handle can be provided on the first section to facilitate rotational locking and rotational unlocking. External threads are provided at the connection point between the second section and the first section and at one end of the third section close to the locking seat 21.

[0069] When the locking rod 22 starts to be locked, after the mounting plate 31 covers the embedding opening 11, the first locking port 341 of the reverse guide rail 34 is docked with the second locking port 121 of the forward guide rail 12 and is in a communicating state. The third section of the locking rod 22 is screwed into the first threaded hole 13. When the third section disengages from the first threaded hole 13, the second section without external threads directly passes through the first locking port 341 and the second locking port 121 along with the third section. Subsequently, the third section moves to the second threaded hole 211, and the connection point between the first section and the second section reaches the first threaded hole 13. Continuing to rotate the first section makes the end of the third section screwed to the second threaded hole 211 of the locking seat 21, and the connection point between the second section and the first section is screwed to the first threaded hole 13. At this time, the entire locking rod 22 passes through the box body 1, the forward guide rail 12, the reverse guide rail 34 and the locking seat 21, so that the reverse guide rail 34 cannot move along the forward guide rail 12, achieving the locking effect.

[0070] External threads are provided at the connection point between the first section and the second section of the locking rod 22, and external threads are provided at the end of the third section far from the first section. When the two sections of external threads are locked, they are respectively screwed to the first threaded hole 13 and the second threaded hole 211. The two-point screwing provides stable firmness. During the unlocking or insertion process, the second section without external threads directly passes through the first locking port 341 and the second locking port 121, thereby improving the convenience of locking, without the need to rotate too many turns, and improving the use convenience of locking or unlocking.

[0071] Furthermore, reference Figure 6As shown, there are two sets of first locking ports 341. The two sets of first locking ports 341 are respectively located at one end of the reverse guiding rail 34 close to the mounting plate 31 and at one end far from the mounting plate 31. The two sets of first locking ports 341 are provided to set two locking positions for the fan assembly 3 that can be switched.

[0072] When the locking rod 22 locks the first locking port 341 at the end of the reverse guiding rail 34 close to the mounting plate 31, the fan assembly 3 is in a closed state and can operate normally. When the locking rod 22 disengages from the first locking port 341 and the second locking port 121, the reverse guiding rail 34 can move along the forward guiding rail 12. During the movement, the first locking port 341 at the end far from the mounting plate 31 is docked with the second locking port 121, and then the locking rod 22 is inserted for locking. At this time, several fans 33 extend outside the embedding port 11 and will not disengage from the embedding port 11, so that several fans 33 can be repaired or cleaned, and the stability of several fans 33 is ensured. Several fans 33 will not disengage from the embedding port 11 and the box body 1. In this way, several fans 33 can be repaired and cleaned without being disassembled from the box body 1 or the embedding port 11, saving the disassembly and assembly links and improving the efficiency of repair or cleaning.

[0073] Furthermore, referring to Figure 6 As shown, a first limiting block is also provided at the first locking port 341 at the end far from the mounting plate 31, and a second limiting block (not labeled in the figure) is provided at the second locking port 121. When the first locking port 341 at the end far from the mounting plate 31 moves to the second locking port 121 along with the reverse guiding rail 34, the first limiting block abuts against the second limiting block, and the first locking port 341 is docked with the second locking port 121, so as to quickly position the positions of the first locking port 341 and the second locking port 121 and improve the positioning speed.

[0074] In some embodiments, referring to Figure 7 As shown, the ventilation duct 32 includes a movable pipe 321 and a fixed pipe 322; the movable pipe 321 is connected to several fans 33, the fixed pipe 322 is installed in the box body 1 and is connected to the air outlet grille 4. The pipe orifices of the movable pipe 321 and the fixed pipe 322 are in mutual abutment. After the movable pipe 321 receives the wind power conveyed by several fans 33, it conveys the wind power to the fixed pipe 322, and then the fixed pipe 322 conveys the wind power to the air outlet grille 4. When several fans 33 move along with the reverse guiding rail 34, the docking or separation of the movable pipe 321 and the fixed pipe 322 can be switched. When the locking mechanism 2 locks the first locking port 341 close to the mounting plate 31, the movable pipe 321 and the fixed pipe 322 are in a docked state, and several fans 33 can convey the wind power. When the locking mechanism 2 locks the first locking port 341 far from the mounting plate 31, the movable pipe 321 and the fixed pipe 322 are in a separated state, so that several fans 33 and the movable pipe 321 can be maintained or repaired.

[0075] Furthermore, referring to Figure 7 as shown, a conical rubber ring 3221 is provided at the pipe orifice of the fixed pipe 322, and an abutting rubber ring 3211 is provided at the pipe orifice of the movable pipe 321. When the movable pipe 321 abuts against the fixed pipe 322, the abutting rubber ring 3211 abuts against the conical rubber ring 3221. By using the inner wall of the abutting rubber ring 3211 to abut against the conical rubber ring 3221, when pneumatically conveying, the leakage of air flow from the butt joint of the fixed pipe 322 and the movable pipe 321 can be reduced, and the airtightness of the air flow conveying can be improved.

[0076] Still further, an electromagnet ring 3222 and a sealing ring 3223 are provided on the fixed pipe 322; the sealing ring 3223 is sleeved on the fixed pipe 322 and can slide along the outer wall of the fixed pipe 322. When the sealing ring 3223 slides to the conical rubber ring 3221, it abuts against the outer wall of the conical rubber ring 3221. The inner diameter of the sealing ring 3223 is larger than the outer diameter of the movable pipe 321, so that the outer wall of the conical rubber ring 3221 is pressed tightly against the movable pipe 321 to further improve the sealing effect.

[0077] The electromagnet ring 3222 is sleeved on the side away from the conical rubber ring 3221, and an elastic part 3224 is provided between the electromagnet ring 3222 and the sealing ring 3223. The elastic part 3224 can adopt a plurality of springs. The sealing ring 3223 is magnetically connected to the electromagnet ring 3222. A iron sheet is provided on the side of the sealing ring 3223 close to the electromagnet ring 3222 to facilitate the magnetic attraction between the sealing ring 3223 and the electromagnet ring 3222. The plurality of springs provide the pressure for the sealing ring 3223 to press the conical rubber ring 3221 and the movable pipe 321.

[0078] The electromagnet ring 3222 contains a signal transceiver, which can be powered on or off by sending and receiving signal instructions. When powered on, the electromagnet ring 3222 generates magnetic force, and the magnetic force is greater than the elastic force of the elastic part 3224, so that the sealing ring 3223 is adsorbed on the electromagnet ring 3222. When powered off, the adsorption ability due to the magnetic force is lost, and the sealing ring 3223 is affected by the elastic force of the elastic part 3224 and moves to the position of the conical rubber ring 3221, pressing the conical rubber ring 3221 against the outer wall of the movable pipe 321, thereby further improving the sealing performance between the movable pipe 321 and the fixed pipe 322.

[0079] Referring to Figure 5As shown, a sensor switch 212 is provided in the second threaded hole 211. The sensor switch 212 is electrically connected to the electromagnet ring 3222. The electrical connection method can be electrical signal connection or cable data connection, that is, wireless data connection or wired data connection. When the locking rod 22 passes through the first threaded hole 13, the first locking port 341, and the second locking port 121 and is inserted into the second threaded hole 211 of the locking seat 21, it contacts or presses the sensor switch 212. The sensor switch 212 can adopt a pressure sensor. When the pressure sensor is subjected to the pressure of the locking rod 22, the power supply of the electromagnet ring 3222 is disconnected, and the electromagnet ring 3222 loses its magnetic force. The sealing ring 3223 moves to the conical rubber ring 3221 under the elastic force of the elastic part 3224 and presses the moving tube 321.

[0080] When the locking rod 22 rotates in the reverse direction and disengages from the second threaded hole 211 of the locking seat 21, the sensor switch 212 that has lost pressure turns on the energized state of the electromagnet ring 3222. After the electromagnet ring 3222 is energized, the sealing ring 3223 is subjected to a magnetic force greater than the elastic force, so as to disengage from the conical rubber ring 3221, enabling the moving tube 321 to disengage from the fixed tube 322.

[0081] By means of the cooperation between the sensor switch 212 and the locking rod 22 to connect and disconnect the power supply of the electromagnet ring 3222, it is convenient to close or open the conical rubber ring of the sealing ring 3223, providing a stable sealing effect while achieving the function of conveniently switching the sealing or separating state of the sealing ring 3223.

The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
