DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment: A rotary motor housing structure, such as Figure 1-Figure 5As shown, it includes a housing 1, and a front cover 2 and a rear cover 3 installed at both ends of the housing 1. The front cover 2 and the rear cover 3 are both provided with heat dissipation holes 23. The heat dissipation holes 23 are provided to facilitate the entry of external air into the housing 1 for air flow and heat dissipation.

[0025] Furthermore, the outer surface of the casing 1 is sleeved with a shell 4 coaxial with the casing 1, the shell 4 is a hollow cylindrical structure, and the two end surfaces are annular surfaces, four first through holes 5 and four second through holes 6 are circumferentially opened at the two ends of the shell 4, and the first through holes 5 are opposite to the second through holes 6 one by one, that is, the first through holes 5 and the corresponding second through holes 6 are coaxially arranged, and the two ends of the shell 4 are respectively provided with a first cover plate 7 for covering the first through holes 5 and a second cover plate 8 for covering the second through holes 6, a rotating rod 9 is provided in the shell 4, and the two ends of the rotating rod 9 are respectively rotatably connected to the two ends of the shell 4, and the two ends of the rotating rod 9 are respectively connected to the edges of the inner walls of the first cover plate 7 and the second cover plate 8 after passing through the shell 4, that is, the first cover plate 7 is connected to the second cover plate 8 through the rotating rod 9, and when the second cover plate 8 rotates with the rotating rod 9 as the axis, the first cover plate 7 is driven to rotate synchronously in the same direction through the rotating rod 9.

[0026] A rotating wheel 10 is provided on the outer side of the rear cover 3, and a first connecting rod 11 is hinged on the edge of the rotating wheel 10. The end of the first connecting rod 11 is hinged on the edge of the second cover plate 8. A driving assembly 12 is provided in the casing 1, and the driving assembly 12 is connected to the rotating wheel 10, and can drive the rotating wheel 10 to rotate reciprocatingly 90°. During the reciprocating rotation of the rotating wheel 10, since the rotating wheel 10 is connected to the second cover plate 8 through the first connecting rod 11, the second cover plate 8 reciprocates around the rotating rod 9 as the axis, thereby reciprocatingly opening and closing the second through hole 6. At the same time, since the first cover plate 7 and the second cover plate 8 rotate synchronously in the same direction, the first cover plate 7 also rotates reciprocatingly to reciprocate and open and close the first through hole 5, that is, the first through hole 5 and the second through hole 6 are opened and closed synchronously.

[0027] A nozzle 13 is installed on the inner wall of the housing 4, the nozzle of the nozzle 13 faces the outer surface of the housing 1, the nozzle 13 is connected to a connecting pipe 14, and is connected to the output end of a water pump 15 through the connecting pipe 14, and the input end of the water pump 15 is connected to a water tank 16. When in use, water is loaded into the water tank 16, and when the water pump 15 and the nozzle 13 are turned on, the water in the water tank 16 is pumped to the nozzle 13 through the connecting pipe 14, and the nozzle 13 sprays mist water toward the outer surface of the housing 1, and the mist water vaporizes and dissipates heat to the inner cavity of the housing 1 and the housing 4.

[0028] Specifically: when the rotary motor is running, the heat generated by it is conducted to the casing 1 and radiated to the inner cavity of the casing 4 through the casing 1; when the first cover plate 7 and the second cover plate 8 respectively cover the first through hole 5 and the second through hole 6, the inner cavity of the casing 4 is not connected with the outside world, and heat accumulates on the outer surface of the casing 1 and the inner cavity of the casing 4. At this time, the nozzle 13 sprays mist water to the outer surface of the casing 1, and the mist water absorbs heat and vaporizes to form hot air, and increases the air pressure in the inner cavity of the casing 4; when the first cover plate 7 and the second cover plate 8 rotate to open the first through hole 5 and the second through hole 6, the inner cavity of the casing 4 is connected with the outside world, and the hot air quickly flows to the outside world through the first through hole 5 and the second through hole 6, and the outside air flows to the inner cavity of the casing 4 through the first through hole 5 and the second through hole 6, forming air flow, dissipating the heat of the outer surface of the casing 1 and the inner cavity of the casing 4, repeating the cycle, and cooperating with the air flow heat dissipation of the heat dissipation holes 23 set in the front cover 2 and the rear cover 3, effectively reducing the overall temperature of the rotary motor.

[0029] By setting the nozzle 13, the nozzle 13 sprays atomized water. On the one hand, after the water is atomized, the area in contact with the heat increases, the heat absorption area increases, and the heat absorption effect is improved; on the other hand, after the water is atomized, it can contact with the heat more fully, so that it is quickly vaporized, and the vaporization rate is improved. After vaporization to form hot air, the air pressure in the inner cavity of the shell 4 increases, and cooperates with the heat radiated by the casing 1 to form high pressure and high temperature. When the first through hole 5 and the second through hole 6 are opened, the hot air flows quickly to the outside under the action of the diameter change and air pressure of the first through hole 5 and the second through hole 6, taking away the heat. At the same time, the outside air is replenished into the inner cavity of the shell 4, forming a state of rapid air flow.

[0030] Preferably, the housing 1, the outer shell 4, the front cover 2 and the rear cover 3 are made of materials with excellent thermal conductivity to facilitate heat conduction and heat dissipation.

[0031] Preferably, a heat-conducting column 22 is installed on the inner wall of the outer shell 4, and the end of the heat-conducting column 22 abuts the outer surface of the casing 1; by providing the heat-conducting column 22, on the one hand, the outer shell 4 can be supported by the heat-conducting column 22, and on the other hand, the heat can be effectively conducted to the outer shell 4 through the heat-conducting column 22, and the heat is radiated outward through the outer shell 4.

[0032] Preferably, the water tank 16 and the water pump 15 are installed away from the casing 1 to prevent the water in the water tank 16 from absorbing the heat radiated outward from the casing 1, thereby increasing the temperature of the water and reducing the evaporation heat dissipation effect.

[0033] Further, such as Figure 4As shown, the driving assembly 12 includes a turntable 1201 located in the housing 1, and a first groove 1202 is opened on the side of the turntable 1201 facing the back cover 3. The first groove 1202 is circular and is coaxially arranged with the turntable 1201. A quarter-tooth gear 1203 is fixedly installed at the bottom of the first groove 1202. The quarter-tooth gear 1203 is coaxially arranged with the turntable 1201, and a quarter-tooth gear ring 1204 is installed on the groove wall of the first groove 1202. A main gear 1205 is arranged in the first groove 1202, and the quarter-tooth gear 1203 and the quarter-tooth gear ring 1204 are alternately meshed with the main gear 1205.

[0034] Specifically, when the turntable 1201 rotates counterclockwise and maintains, the quarter-tooth gear 1203 is synchronously driven to rotate counterclockwise. When the quarter-tooth gear 1203 rotates to mesh with the main gear 1205, the main gear 1205 is driven to rotate clockwise. When the quarter-tooth gear 1203 rotates to disengage with the main gear 1205, the quarter-tooth ring 1204 meshes with the main gear 1205 and drives the main gear 1205 to rotate counterclockwise. When the quarter-tooth ring 1204 disengages with the main gear 1205, the main gear 1205 does not rotate, and the quarter-tooth gear 1203 and the quarter-tooth ring 1204 rotate counterclockwise with the turntable 1201 until the quarter-tooth gear 1203 meshes with the main gear 1205 again, and this cycle repeats, causing the main gear 1205 to rotate back and forth 90°, that is, the main gear 1205 rotates alternately 90° clockwise and counterclockwise.

[0035] like Figure 5 As shown, a second groove 301 is provided on one side of the rear cover 3 facing the rotating disk 1201. The second groove 301 is circular and is coaxially arranged with the rear cover 3. A driving wheel 1206 and a driven wheel 1207 are arranged in the second groove 301. The driving wheel 1206 and the driven wheel 1207 are jointly sleeved with a belt 1208 and are connected by the belt 1208. That is, the driving wheel 1206 and the driven wheel 1207 rotate synchronously in the same direction, and the driving wheel 1206 is connected to the rear cover 1206 in rotation. 3. A second connecting rod 1209 is installed on the driving wheel 1206, and the end of the second connecting rod 1209 is connected to the main gear 1205, that is, the main gear 1205 drives the driving wheel 1206 to rotate synchronously in the same direction through the second connecting rod 1209. A third connecting rod 1210 is installed on the driven wheel 1207, and the end of the third connecting rod 1210 passes through the rear cover 3 and is connected to the rotating wheel 10, that is, the driven wheel 1207 drives the rotating wheel 10 to rotate synchronously in the same direction through the third connecting rod 1210.

[0036] like Figure 3-Figure 5As shown, when the quarter-tooth gear 1203 drives the main gear 1205 to rotate clockwise, the main gear 1205 drives the driving wheel 1206 to rotate clockwise synchronously through the second connecting rod 1209. Since the driving wheel 1206 is connected to the driven wheel 1207, and the driven wheel 1207 is connected to the rotating wheel 10 through the third connecting rod 1210, the rotating wheel 10 rotates clockwise synchronously. The rotating wheel 10 drives the second cover plate 8 to rotate clockwise through the first connecting rod 11, and the second through hole 6 is gradually opened to the maximum. At the same time, since the second cover plate 8 is connected to the first cover plate 7 through the rotating rod 9, the first cover plate 7 rotates synchronously, and the first through hole 5 is gradually opened to the maximum.

[0037] When the quarter-tooth gear 1203 rotates to disengage with the main gear 1205, the first through hole 5 and the second through hole 6 are maximally open, and at this time, the quarter-tooth gear ring 1204 meshes with the main gear 1205, driving the main gear 1205 to rotate counterclockwise, and the main gear 1205 drives the driving wheel 1206 to rotate counterclockwise synchronously through the second connecting rod 1209, thereby causing the rotating wheel 10 to rotate counterclockwise synchronously, and the rotating wheel 10 drives the second cover plate 8 to rotate counterclockwise through the first connecting rod 11, gradually closing the second through hole 6 to be completely, and the first cover plate 7 rotates counterclockwise synchronously under the drive of the rotating rod 9, gradually closing the first through hole 5 to be completely.

[0038] When the quarter-tooth ring 1204 is not engaged with the main gear 1205, the first through hole 5 and the second through hole 6 are completely closed, and the turntable 1201 continues to rotate counterclockwise. At this time, the main gear 1205 does not rotate, and the first through hole 5 and the second through hole 6 remain closed. At this stage, the nozzle 13 sprays mist water, and the mist water absorbs heat and vaporizes.

[0039] When the quarter-tooth ring 1204 is not meshed with the main gear 1205 and the turntable 1201 rotates 180° counterclockwise, the quarter-tooth gear 1203 meshes with the main gear 1205 again, and the main gear 1205 rotates clockwise, and the first through hole 5 and the second through hole 6 are gradually opened to the maximum. At this time, the hot air in the outer shell 4 flows quickly to the outside, taking away the heat, and the outside air is replenished into the inner cavity of the outer shell 4 to form air flow.

[0040] The rotating wheel 10 is rotated 90° back and forth by rotating the rotating disk 1201, so that the first cover plate 7 and the second cover plate 8 respectively open and close the first through hole 5 and the second through hole 6 back and forth for vaporization and heat dissipation. The main gear 1205 is driven to rotate by the quarter-tooth gear 1203 and the quarter-tooth gear ring 1204. On the basis of realizing the reciprocating 90° rotation of the main gear 1205, sufficient time is provided for the atomized water to absorb heat and vaporize, thereby improving the atomized water heat absorption effect, thereby improving the heat dissipation effect.

[0041] Further, such as Figure 2As shown, a rotor 17 is provided in the casing 1, a reducer 18 is installed at one end of the rotor 17, a drive shaft 19 is installed at the output end of the reducer 18, the end of the drive shaft 19 is connected to the turntable 1201, and the turntable 1201 and the drive shaft 19 are coaxially arranged; when the rotary motor is running, the rotor 17 rotates under the action of electromagnetic force, and the turntable 1201 is driven to rotate by the rotor 17, so that there is no need to set up an additional power device for the turntable 1201, the overall structure of the rotary motor is simplified, and the energy utilization rate is improved.

[0042] A light emitter 20 is installed on the driving shaft 19, and a light receiver 21 is installed on the inner wall of the casing 1. When the driving shaft 19 rotates, the light emitter 20 rotates along with the driving shaft 19. When the driving shaft 19 rotates until the light emitter 20 and the light receiver 21 correspond to each other, the light receiver 21 receives the light beam emitted by the light emitter 20, triggering the water pump 15 and the nozzle 13 to open.

[0043] Preferably, the outer side surface of the rear cover 3 is flush with the end surface of the housing 4 having the second through hole 6, which, on the one hand, improves the aesthetics; on the other hand, facilitates the first connecting rod 11 to drive the second cover plate 8 to rotate to avoid interference.

[0044] like Figure 3 As shown, the housing 4 includes a first housing 401 and a second housing 402 that can be docked. The first housing 401 and the second housing 402 have the same structure. Both ends of the first housing 401 are provided with first fixing ears 403 extending outwards, and both ends of the second housing 402 are provided with second fixing ears 404 extending outwards. The first housing 401 and the second housing 402 are fixedly connected by bolts penetrating the first fixing ears 403 and the second fixing ears 404 and then screwing nuts. By setting the housing 4 as a split structure to form the first housing 401 and the second housing 402, the housing 4 can be easily installed on the outer surface of the housing 1, so as to achieve the effect of easy disassembly and maintenance.

[0045] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
