In one embodiment, referring to fig. 1 to 4, a supporting mechanism 100 includes: a chassis 12, a bracket 11, a transmission assembly 16 and a first motor 161. A first receiving cavity 124 is provided in the chassis 12. The bracket 11 is installed on the chassis 12, and the air outlet assembly 200 is installed on the bracket 11. The transmission assembly 16 and the first motor 161 are both located in the first accommodating cavity 124. An output shaft of the first motor 161 is drivingly connected to the transmission assembly 16. The transmission assembly 16 is connected with the chassis 12, and one of the first motor 161 and the bracket 11 is in transmission fit. The first motor 161 is used to drive the support 11 to rotate on the chassis 12 around its axis through the transmission assembly 16.

In the assembly process of the support mechanism 100, the transmission assembly 16 is connected to the first motor 161; then, the first motor 161 is in transmission fit with the bracket 11, and the other end of the transmission assembly 16 is connected to the chassis 12, or the first motor 161 is connected to the chassis 12, and the other end of the transmission assembly 16 is in transmission fit with the bracket 11; next, the support 11 is mounted on the chassis 12 to form the support mechanism 100; finally, the air outlet assembly 200 is mounted on the supporting mechanism 100, and the spraying assembly 300 is mounted on the air outlet device. Because the support 11 is connected with the chassis 12 through the transmission of the first motor 161 and the transmission component 16, the first motor 161 is started to drive the transmission component 16 to move, so that the transmission component 16 drives the support 11 to circularly reciprocate or rotate 360 degrees on the chassis 12, namely, the air outlet component 200 can realize automatic rotation when blowing air, adjust the left and right air supply angles, and enlarge the air supply range. Meanwhile, the water mist sprayed out of the spraying assembly 300 is blown out along with the blowing of the air supply assembly, so that the air supply assembly is favorable for cooling and humidifying at the same time, a plurality of fan devices are not needed, and the purchase cost and the energy consumption are also reduced.

In addition, in this embodiment, the support 11 is rotatably connected to the chassis 12, and the air outlet assembly 200 is mounted on the support 11, so that the air outlet assembly 200 can rotate on the chassis 12 around its own axis along with the support 11, which is beneficial to adjusting the left and right air supply angles and expanding the air supply range.

In the present embodiment, the rotation mode of the bracket 11 mounted on the chassis 12 is a reciprocating rotation, and the rotation angle is 65 °, but the present invention is not limited thereto.

It should be noted that a drive fit is understood as: the transmission force of the transmission assembly 16 or the first motor 161 can be transmitted to the bracket 11 to drive the bracket 11 to rotate on the chassis 12. Wherein, the transmission fit's realization mode has two kinds: firstly, the transmission component 16 or the first motor 161 is directly connected with the bracket 11 in a transmission way; secondly, the transmission assembly 16 or the first motor 161 is indirectly in transmission connection with the support 11, that is, an intermediate structure is further arranged between the support 11 and the chassis 12, the transmission assembly 16 or the first motor 161 is directly in transmission connection with the intermediate structure, and indirect transmission is achieved for the support 11 through the intermediate structure.

It should be further noted that, one of the transmission assembly 16 and the first motor 161 is in transmission fit with the bracket 11, and the other is connected with the chassis 12, which is understood as follows: the transmission assembly 16 and the first motor 161 are driven in two ways. First, the first motor 161 is in transmission fit with the bracket 11, and the transmission assembly 16 is linked with the chassis 12, so that the relative positions of the first motor 161 and the bracket 11 are kept unchanged, and the bracket 11 and the first motor 161 are driven to rotate together through power transmission; secondly, the transmission assembly 16 is in transmission fit with the support 11, the first motor 161 is connected with the chassis 12, the relative position of the first motor 161 on the chassis 12 is unchanged, and the support 11 is pushed to rotate around the axis of the support 11 through output power. Meanwhile, the structure of the transmission assembly 16 has various structures, and it is only necessary to convert the power of the first motor 161 into the rotation power of the bracket 11, for example: the transmission assembly 16 may be a crank and rocker mechanism, a gear set structure, a combination structure of a master wheel, a slave wheel and a synchronous belt, etc.

Further, referring to fig. 3, the chassis 12 includes a chassis 12 and a base 13. The base 13 is rotatably mounted on the chassis 12, a first accommodating cavity 124 is defined between the chassis 12 and the base 13, one of the transmission components 16 and the first motor 161 is in transmission connection with the base 13, the other one is connected with the chassis 12, and the support 11 is mounted on the base 13.

Alternatively, the shape of the housing 13 may be various, such as a rectangle, a square, a regular hexagon, a regular octagon, or other shapes.

In one embodiment, referring to fig. 3, the base 13 is circular, and the opening of the first accommodating cavity 124 is circular. Therefore, the base 13 is set to be circular, so that no extra volume is added during rotation, which is beneficial to saving the volume of the chassis 12 and the space of the first accommodating cavity 124, and making the structure more compact and stable.

Further, referring to fig. 7, the diameter of the base 13 is larger than the diameter of the opening of the first accommodating cavity 124. When the outdoor water-proof spraying fan 400 is used outdoors, rainwater on the base 13 cannot flow into the first accommodating cavity 124, so that the first accommodating cavity 124 is kept dry, the motor and the transmission assembly 16 in the first accommodating cavity 124 are protected from being corroded by water to cause damage and failure, and the water-proof effect of the spraying fan 400 is improved.

In one embodiment, referring to fig. 3, a fixing hole 131 is formed on a surface of the base 13 facing the bracket 11, and a second surrounding edge 132 is disposed around the fixing hole 131. When the bracket 11 is connected with the base 13, water cannot permeate into the first accommodating cavity 124 from the fixing hole 131 due to the blocking of the second surrounding edge 132, so that the first accommodating cavity 124 is kept dry, the motor and the transmission assembly 16 in the first accommodating cavity 124 are protected from being damaged and lost due to water erosion, and the waterproof effect of the spray fan 400 is improved.

Alternatively, the second surrounding edge 132 may be adhered, integrally formed with the housing 13, or other connecting means.

In one embodiment, referring to fig. 1 and 7, the housing 13 is circumferentially provided with a third surrounding edge 136. A fourth peripheral edge 156 is provided on the chassis 12. The fourth peripheral edge 156 is disposed about the periphery of the housing 13. It can be seen that when the base 13 is connected to the base 12, the third peripheral edge 13 surrounds the fourth peripheral edge 156, and when water flows down on the base, the water flows down along the third peripheral edge 136. And water does not seep back into the first receiving cavity 124 of the chassis 12 due to the blocking of the fourth peripheral edge 156. The drying in the first accommodating cavity 124 is kept, the motor and the transmission assembly 16 in the first accommodating cavity 124 are protected from being damaged and failed due to water erosion, and the waterproof effect of the spray fan 400 is improved.

Alternatively, the third surrounding edge 136 may be adhered, sleeved, integrally formed with the base 13, or other connecting means. The fourth peripheral edge 156 may be adhered, sleeved, integrally formed with the chassis 12, or otherwise connected.

Further, a rubber sheath 126 is arranged between the connection between the base 13 and the chassis 12. Thus, the abrasion between the protective base 13 and the chassis 12 is reduced, so that the quality and the use effect of the spray fan 400 are improved.

In one embodiment, referring to fig. 3, a supporting shaft 122 is disposed in the chassis 12, and the base 13 is mounted on the supporting shaft 122 through a bearing 151. Therefore, the friction force between the base 13 and the chassis 12 is reduced by the bearing 151 during rotation, so that the chassis 12 can provide a force for the support 11 and the air outlet assembly 200 on the support 11 to lift upwards, which is beneficial to the smoother and lighter left-right swing of the spray fan 400.

Alternatively, the type of bearing 151 may be a rolling bearing, a knuckle bearing, a sliding bearing, or other bearing types. When the bearing 151 is a rolling bearing, the rolling bearing may be a ball bearing, a cylindrical roller bearing, a needle bearing, a tapered roller bearing, a self-aligning roller bearing, or the like.

Further, the bearing 151 is disposed to be sleeved on the support shaft 122, and the base 13 is mounted on the support shaft 122 through the bearing 151. Therefore, the base 13 can rotate on the chassis 12, which is beneficial to the smoother and lighter left-right swing of the spray fan 400.

In one embodiment, referring to fig. 1, the chassis 12 includes a bottom shell 15 and an upper lid 128 mounted on the bottom shell 15. The support shaft 122 is disposed within the upper cover 128. The base 13 is mounted on the upper cover 128 and encloses a first receiving chamber 124 with the upper cover 128. The supporting shaft 122 is provided with a through hole 121, and the bottom case 15 is provided with a top shaft 154. The top shaft 154 penetrates the through hole 121 and pushes the bearing 151 against the housing 13. Therefore, in the assembly process, after the bottom shell 15, the upper cover 128 and the base 13 are assembled in sequence, the bearing 151 is supported by the top shaft 154 of the bottom shell 15 penetrating into the through hole 121, so that the bearing 151 is firmly fixed between the supporting shaft 122 and the base 13. Meanwhile, the structure of the chassis 12 is more compact, which is beneficial to saving the movement space of the first motor 161 and the transmission assembly 16 in the first accommodating cavity 124, and improving the quality of the spray fan 400.

Alternatively, the upper cover 128 may be mounted to the bottom case 15 by bolting, riveting, bonding, or other means. Of course, indirect mounting between the upper cover 128 and the bottom case 15 may also be adopted, such as: a mounting structure is provided on the bottom housing 15 and the upper cover 128 is mounted to the mounting structure such that the upper cover 128 is indirectly mounted to the bottom housing 15. Thus, the bottom shell 15 is convenient to disassemble and assemble through the fixing structure; and also facilitates more stable attachment of the upper cover 128 to the bottom housing 15.

Further, please refer to fig. 1, a rotating flat pad 152 and a clearance-avoiding rubber pad 153 are further disposed between the connection between the bearing 151 and the base 13, so that the base 13 can be better connected with the bearing 151, thereby reducing or even avoiding the phenomena of slipping and idling, and further facilitating to improve the structural stability of the spray fan 400, and further improving the usability of the product.

Therefore, the second accommodating cavity 155 is beneficial to the conduit 33 and the signal wire to be arranged and hidden in the spraying fan 400, and the sealing performance and the waterproof effect of the spraying fan 400 are further improved. On the other hand, the second accommodating cavity 155 is beneficial to saving materials of the chassis 12, so that the production cost is reduced.

It should be noted that the second mounting hole 133, the through hole 121 and the first mounting hole 125 are used for sequentially penetrating the conduit 33 and/or the signal line, and it should be understood that: the second mounting hole 133, the through hole 121 and the first mounting hole 125 are used for sequentially and simultaneously penetrating the guide tube 33 and the signal line; alternatively, the second mounting hole 133, the through hole 121, and the first mounting hole 125 are used to sequentially penetrate the guide tube 33; alternatively, the second mounting hole 133, the through hole 121, and the first mounting hole 125 are used to sequentially insert signal lines.

Alternatively, the number of the first mounting holes 125 is one, two, or more. Meanwhile, the number of the rubber sheath 126 and the through quick connector 127 is one, two or more.

Specifically, a rubber sheath 126 is further disposed on the first mounting hole 125. In this manner, the conduit 33 and/or signal wires are threaded through the rubber boot 126 into the receiving cavity, which facilitates protecting the wires and/or signal wires from damage by the walls of the mounting hole.

Further, a through quick connector 127 is disposed on the first mounting hole 125. Thus, the external lead and/or the water pipe can be directly connected with the through quick connector 127, which is beneficial to the installation, the disassembly and the transportation of the spray fan 400 and is also beneficial to improving the whole sealing performance of the spray fan 400.

Therefore, when the first motor 161 is powered on, the first transmission member 163 connected to the output shaft is driven to rotate; after the first transmission member 163 rotates, the second transmission member 162 is driven to swing. Because one end of the second transmission member 162 is connected to the chassis 12, and the chassis 12 is in a fixed state, in the driving process of this embodiment, the chassis 12 is used as a support base, and the reverse thrust power is transmitted to the first motor 161 through the second transmission member 162 and the first transmission member 163, so that the first motor 161 rotates and drives the base 13 to rotate reciprocally, thereby realizing the automatic rotation of the spray fan 400 around the support shaft 122.

Specifically, the first transmission member 163 is rotatably connected to the second transmission member 162, and the second transmission member 162 is rotatably connected to the chassis 12. Thus, the base 13 drives the first transmission member 163 and the second transmission member 162 to perform a link movement when rotating, which is beneficial to realize the rotation and air supply of the spray fan 400.

Further, the first transmission member 163 is an eccentric wheel. The eccentric is connected with the output shaft of the first motor 161 to form a cam mechanism.

It should be noted that a rolling fit is understood as: by the rolling of the rolling members 135, the sliding friction force of the rotation of the housing 13 on the chassis 12 is dispersed into the static friction force of a plurality of small contact areas on the rolling members 135, so that the friction force is reduced. Meanwhile, the rolling members 135 are installed between the housing 13 and the chassis 12 in two ways: the first is that the rolling member 135 is installed on the side of the base 13 facing the chassis 12, and the rolling member 135 is integrally formed with the base 13 to be rolled and engaged on the chassis 12 and rotated. Secondly, the rolling members 135 are mounted on the chassis 12, and the housing 13 is rollingly engaged and rotated on the whole formed by the rolling members 135 and the chassis 12.
