[0031] Throughout the specification, when a device is said to be "connected" to another device, this includes not only the case of "direct connection" but also the case of "indirect connection" by placing other elements therebetween. In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0032] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0033] The embodiment of the present application discloses an outdoor fan.

[0034] An outdoor fan, reference Figure 1 and Figure 2 As shown, it includes a box body 1, which provides installation and protection. The interior of the box body 1 is an installation space, and is provided with a plurality of mounting frames 10 for fixing and supporting, which provide fixation and installation of other components.

[0035] The box body 1 includes 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 in one end of the box body 1, and the air outlet grille 4 may also be provided with a control switch and an adjustment switch for adjusting and controlling the overall opening and closing of the outdoor fan, and the air outlet grille 4 provides air outlet for the outdoor fan. The air outlet grille 4 is aimed at the user to achieve the effect of air cooling, speeding up the air flow speed of the surrounding environment, so as to provide the function of regulating the ambient temperature.

[0036] If further cooling effect is required, a refrigeration structure such as a compressor can be provided to further achieve the cooling effect.

[0037] 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 changing the flow speed of the ambient gas. During outdoor use, the fan assembly 3 is prone to draw in too much dust, hay, branches, leaves and other debris, which causes dust to accumulate or debris to accumulate inside the fan. If it is not cleaned for a long time, it is easy to be damaged. Therefore, the fan assembly 3 is slidably connected to one end of the box body 1 to facilitate sliding out from one end of the box body 1 for easy maintenance or cleaning.

[0038] The battery pack 5 is installed on the mounting frame 10, and the battery pack 5 provides power supply. The battery pack 5 is also connected to an inverter, which converts the direct current of the battery pack 5 into alternating current to ensure that the fan assembly 3 can obtain a stable alternating current power supply.

[0039] The locking mechanism 2 is installed on the side wall of the box body 1 and is engaged with the fan assembly 3 to provide a locking effect on the fan assembly 3. The locking mechanism 2 is used to fix 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 ends the locking effect, the fan assembly 3 loses its fixing effect and can be taken out from the box body 1 to achieve the effect of convenient maintenance.

[0040] Specifically, after the battery pack 5 transmits electricity to the fan assembly 3, the fan assembly 3 forms an airflow and transmits it to the air outlet grille 4, so that the outdoor environment is cooled down. 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, thereby partially detaching from the box body 1, and the fan assembly 3 can be repaired or cleaned to achieve the purpose of convenient maintenance.

[0041] For further reference, Figure 3 As shown, the fan assembly 3 includes a mounting plate 31, a ventilation duct 32 and a plurality of fans 33; an embedding opening 11 is opened on the box body 1, and the mounting plate 31 is snap-fitted with the embedding opening 11, so that the mounting plate 31 covers the embedding opening 11, making the appearance beautiful.

[0042] A plurality of fans 33 are mounted on the mounting plate 31 and are connected to the mounting plate 31 by bolts. In this embodiment, the number of the plurality of fans 33 is three, as shown in the figure.

[0043] A positive guide rail 12 is provided in the box body 1, and a reverse guide rail 34 is provided on the side of the mounting plate 31 close to the box body 1. The reverse guide rail 34 is slidably connected to the positive guide rail 12. An inner groove is provided on the positive 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 guide protrusion is consistent with the style of the inner groove, and can be T-shaped or arc-shaped to ensure that the reverse guide rail 34 cannot be separated from the positive guide rail 12, but can slide along the positive guide rail 12.

[0044] A plurality of fans 33 are connected to a ventilation duct 32 at one end away from the mounting plate 31. The ventilation duct 32 is connected to 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, preferably a circular duct. The figure takes a rectangular duct as an example.

[0045] The reverse guide rail 34 is connected to the locking mechanism 2. When the reverse guide rail 34 is inserted into the forward guide rail 12, it 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, thereby achieving a locking effect.

[0046] Specifically, after the fans 33 are installed on the mounting plate 31, the mounting plate 31 is inserted into the embedding opening 11, and 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 fans 33 enter the box body 1 until the mounting plate 31 closes the embedding opening 11. The locking mechanism 2 locks the reverse guide rail 34 to fix the positions of the 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 remove the fans 33 from the embedding opening 11, so as to facilitate maintenance.

[0047] In some embodiments, reference Figure 4 As shown, the mounting plate 31 is divided into two layers of plates. The size of the first layer of plate 311 is larger than the embedding opening 11, so that the first layer of plate 311 can completely cover the embedding opening 11. The size of the second layer of plate 312 is equal to or smaller than the embedding opening 11, so that the second layer of plate 312 can be directly embedded in the embedding opening 11, and the first layer of plate 311 covers the embedding opening 11, thereby completing the sealing effect, ensuring beauty while improving sealing.

[0048] Specifically, the second layer of plate 312 is equal in size to the embedded opening 11 so that the second layer of plate 312 can block the embedded opening 11, and then the first layer of plate 311 which is larger in size than the embedded opening 11 is used to cover the embedded opening 11, thereby closing the embedded opening 11 and reducing air leakage from the embedded opening 11.

[0049] Furthermore, a sealing layer 3112 is provided between the first plate body 311 and the second plate body 312. The sealing layer 3112 is in contact with the box body 1 next to the embedding port 11. The sealing layer 3112 may be a rubber layer. When the first plate body 311 covers the embedding port 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.

[0050] In some embodiments, reference Figure 5As shown, there are four groups of positive guide rails 12 and reverse guide rails 34, and the mounting plate 31 is a rectangular plate, so 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 positive 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 be just embedded in the four groups of positive guide rails 12.

[0051] The four sets of forward guide rails 12 and reverse guide rails 34 can improve the installation stability of the overall mounting plate 31 and the fans 33. The four sets of reverse guide rails 34 can provide better movement stability, prevent the movement position from shifting, and provide a more stable connection.

[0052] In some embodiments, reference 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 next to 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. A reinforcing plate can be provided to improve the stability of the connection of the locking seat 21.

[0053] 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 consistent, and 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.

[0054] A first threaded hole 13 is provided on the box body 1, and a 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 consistent, and the aperture 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 be just inserted into the first threaded hole 13 and the second threaded hole 211. The axes of the first threaded hole 13, the second locking hole 121 and the second threaded hole 211 are on the same horizontal axis, that is, they can be connected to each other.

[0055] When the locking rod 22 passes through the first threaded hole 13 to the first locking opening 341 , the second locking opening 121 and the second threaded hole 211 in sequence, 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 the fans 33 .

[0056] refer to Figure 5 As shown, the locking rod 22 is divided into three sections. The first section is located outside the box body 1. The first section can be provided with a rotating handle to provide rotational locking and rotational unlocking. The connection point between the second section and the first section and the end of the third section close to the locking seat 21 are both provided with external threads.

[0057] When the locking rod 22 is opened for locking, after the mounting plate 31 covers the embedding opening 11, the first locking opening 341 of the reverse guide rail 34 is docked with the second locking opening 121 of the forward guide rail 12, and they are in a connected state. The third section of the locking rod 22 is screwed into the first threaded hole 13. When the third section is disengaged from the first threaded hole 13, the second section without external threads directly follows the third section to pass through the first locking opening 341 and the second locking opening 121. Then 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. The first section continues to be rotated so that the end of the third section is screwed with the second threaded hole 211 of the locking seat 21, and the connection point between the second section and the first section is screwed with 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, thereby achieving a locking effect.

[0058] The locking rod 22 is provided with an external thread through the connection point between the first section and the second section, and an external thread is provided at the end of the third section away from the first section, so that when locking, the two sections of the external thread are respectively screwed with the first threaded hole 13 and the second threaded hole 211, and the two-point screw connection provides stable stability. During the unlocking or insertion process, the second section without the external thread is used to directly penetrate the first locking port 341 and the second locking port 121, thereby improving the convenience of locking without rotating too many times, thereby improving the convenience of locking or unlocking.

[0059] For further reference, Figure 6 As shown, two groups of first locking openings 341 are provided, and the two groups of first locking openings 341 are respectively located at one end of the reverse guide rail 34 close to the mounting plate 31 and one end away from the mounting plate 31 . The two groups of first locking openings 341 are provided with two groups capable of switching the locking positions of the fan assembly 3 .

[0060] When the locking rod 22 locks the reverse guide rail 34 with the first locking hole 341 at one end of 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 hole 341 and the second locking hole 121, the reverse guide rail 34 can move along the forward guide rail 12. During the movement, the first locking hole 341 away from the end of the mounting plate 31 docks with the second locking hole 121, and then the locking rod 22 is inserted for locking. At this time, a number of fans 33 extend out of the embedding hole 11 and will not disengage from the embedding hole 11. The fans 33 can be repaired or cleaned, and the stability of the fans 33 is guaranteed. The fans 33 will not disengage from the embedding hole 11 and the box body 1. This method enables the fans 33 to be repaired and cleaned without being disassembled from the box body 1 or the embedding hole 11, eliminating the disassembly and assembly process and improving the efficiency of repair or cleaning.

[0061] Further, refer to Figure 6As shown, a first limit block is provided at the first locking opening 341 away from one end of the mounting plate 31, and a second limit block (not numbered in the figure) is provided at the second locking opening 121. When the first locking opening 341 away from one end of the mounting plate 31 moves to the second locking opening 121 along the reverse guide rail 34, the first limit block abuts against the second limit block, and the first locking opening 341 and the second locking opening 121 are docked, thereby achieving the effect of quickly positioning the positions of the first locking opening 341 and the second locking opening 121 and improving the positioning speed.

[0062] In some embodiments, reference 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 a plurality of fans 33, the fixed pipe 322 is installed in the box body 1 and connected to the air outlet grille 4, the pipe openings of the movable pipe 321 and the fixed pipe 322 abut against each other, the movable pipe 321 receives the wind power of the plurality of fans 33, and then transmits the wind power to the fixed pipe 322, and then the fixed pipe 322 transmits the wind power to the air outlet grille 4, and when the plurality of fans 33 move along the reverse guide rail 34 The movable tube 321 and the fixed tube 322 can be switched to be docked or separated. When the locking mechanism 2 locks the first locking opening 341 close to the mounting plate 31, the movable tube 321 and the fixed tube 322 are in a docking state, and the fans 33 can transmit wind power. When the locking mechanism 2 locks the first locking opening 341 away from the mounting plate 31, the movable tube 321 and the fixed tube 322 are in a separated state, and the fans 33 and the movable tube 321 can be maintained or repaired.

[0063] For further reference, Figure 7 As shown, a conical rubber ring 3221 is provided at the pipe mouth of the fixed pipe 322, and a contact rubber ring 3211 is provided at the pipe mouth of the movable pipe 321. When the movable pipe 321 contacts the fixed pipe 322, the contact rubber ring 3211 contacts the conical rubber ring 3221. The contact rubber ring 3211 contacts the inner wall of the conical rubber ring 3221, so that during wind transportation, the leakage of airflow from the joint between the fixed pipe 322 and the movable pipe 321 can be reduced, thereby improving the air tightness of airflow transportation.

[0064] Furthermore, an electromagnet ring 3222 and a sealing ring 3223 are provided on the fixed tube 322; the sealing ring 3223 is sleeved on the fixed tube 322 and can slide along the outer wall of the fixed tube 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 tube 321, so that the outer wall of the conical rubber ring 3221 is pressed against the movable tube 321 to further improve the sealing effect.

[0065] 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 3223 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. The sealing ring 3223 is close to the side of the electromagnet ring 3222 and an iron-containing sheet is provided to facilitate the magnetic attraction between the sealing ring 3223 and the electromagnet ring 3222. The plurality of springs provide pressure for the sealing ring 3223 to press the conical rubber ring 3221 and the moving tube 321.

[0066] 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 the power is off, the magnetic adsorption ability is lost, and the sealing ring 3223 is acted upon by the elastic force of the elastic part 3224 to move to the conical rubber ring 3221, and press the conical rubber ring 3221 onto the outer wall of the moving tube 321, thereby further improving the sealing performance between the moving tube 321 and the fixed tube 322.

[0067] refer to Figure 5 As shown, a sensor switch 212 is provided in the second threaded hole 211, and the sensor switch 212 is electrically connected to the electromagnet ring 3222. The electrical connection method can be an electrical signal connection or a cable data connection, that is, a wireless data connection or a 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, the sensor switch 212 is contacted or pressed. 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, the electromagnet ring 3222 loses its magnetic force, and the sealing ring 3223 is moved to the conical rubber ring 3221 by the elastic force of the elastic part 3224, pressing the moving tube 321.

[0068] When the locking rod 22 rotates in the opposite direction and disengages from the second threaded hole 211 of the locking seat 21, the sensor switch 212 loses pressure and turns on the power supply 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, thereby disengaging from the conical rubber ring 3221, so that the movable tube 321 can be disengaged from the fixed tube 322.

[0069] By cooperating with the sensor switch 212 and the locking rod 22 to connect the power supply of the electromagnet ring 3222, the sealing ring 3223 can conveniently close the conical rubber ring or open the conical rubber ring, providing a stable sealing effect while achieving the effect of conveniently switching the sealing ring 3223 to a sealed or separated state.
