Description

Technical Field

[0001] This invention relates to the field of steam cleaning technology, specifically to a high-speed precision gear transmission device for household steam cleaning appliances. Background Technology

[0002] Steam cleaning is a technology that uses high-temperature, high-pressure steam for deep cleaning. It heats water to over 100°C to form steam, which is then sprayed under pressure to remove dirt, kill bacteria, and disinfect. The steam can reach temperatures above 120°C, effectively killing bacteria, viruses, and fungi. It is especially suitable for environments where bacteria can easily grow, such as home textiles. It uses low-pressure steam for gentle cleaning, avoiding scratches or corrosion caused by traditional high-pressure water or chemical agents. It uses only water as the cleaning medium, and no chemical reagents are added during the cleaning process. Only a small amount of condensate remains after cleaning, avoiding chemical residues that could pollute the environment or materials. Therefore, it requires a high-speed, precision gear transmission device for household steam cleaning appliances.

[0003] Most existing household steam cleaning appliances use motors for direct transmission, which has poor transmission stability and is not suitable for precision machinery and high-speed heavy-load scenarios. It cannot reduce dynamic load and achieve smooth transmission, and it cannot lock gears, which may cause accidental rotation. Its poor stability reduces its practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed precision gear transmission device for household steam cleaning appliances, in order to solve the problems mentioned in the background art. Existing household steam cleaning appliances mostly use motors for direct transmission, which has poor transmission stability, is not suitable for precision machinery and high-speed heavy-load scenarios, cannot reduce dynamic load and achieve smooth transmission, and cannot lock the gears, which may cause accidental rotation, resulting in poor stability and reduced practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-speed precision gear transmission device for household steam cleaning appliances, comprising a housing, heat dissipation grooves equally spaced at both ends of the housing, a circular groove at the bottom inner end of the housing, a circular rod rotatably mounted inside the circular groove, a drive gear fixedly mounted on the top of the circular rod, a rotating gear rotatably mounted on the bottom inner end of the housing to the right of the drive gear, the outer surface of the rotating gear meshing with the outer surface of the drive gear, a transmission rod rotatably mounted on the bottom of the housing, the top of the transmission rod penetrating the housing and fixedly connected to the bottom of the rotating gear, a driven pulley rotatably mounted on the top of the housing, a driving pulley rotatably mounted on the top of the housing to the right of the driven pulley, a transmission belt movably mounted on the outer surface of the driven pulley and the outer surface of the driving pulley, a rotating rod fixedly mounted on the top of the drive gear, and a rotary motor fixedly mounted on the top inner end of the housing.

[0006] Preferably, a protective shell is fixedly installed on the top of the housing, and heat dissipation holes are provided at equal intervals at both ends of the protective shell.

[0007] Preferably, a fixing rod is fixedly installed at the bottom of the inner side of the housing. A strip groove is opened inside the fixing rod. A lead screw is rotatably installed inside the strip groove. A threaded sleeve is threaded onto the surface of the lead screw. A movable plate is fixedly installed on the top of the threaded sleeve, and a locking rod is fixedly installed on one side of the movable plate.

[0008] Preferably, a retaining ring is fixedly installed on the top of the rotating gear, and a locking hole is provided around the surface of the retaining ring.

[0009] Preferably, an adjusting motor is fixedly installed on one side of the fixing rod, and the output end of the adjusting motor passes through the fixing rod and is fixedly connected to one side of the lead screw.

[0010] Preferably, crossbars are fixedly installed at both ends of the bottom of the housing, and each crossbar has a groove inside. A slider is movably installed inside each groove, and a connecting rod is fixedly installed on the opposite side of each slider. One end of the connecting rod is fixedly connected to one end of the moving plate.

[0011] Preferably, the top of the rotating rod passes through the housing and is fixedly connected to the bottom of the driven pulley, and the output end of the rotary motor passes through the housing and is fixedly connected to the bottom of the driving pulley. Compared with the prior art, the beneficial effects of the present invention are: This high-speed precision gear transmission device for household steam cleaning appliances operates by having the operator start a rotary motor. The motor's operation causes the drive pulley to rotate, which in turn drives the transmission belt. The transmission belt then drives the driven pulley, which in turn drives a rotating rod. This rotating rod, in turn, drives a drive gear. The drive gear then drives a circular rod to rotate within a circular groove. Simultaneously, the drive gear drives a rotating gear, which in turn drives the transmission rod. Thus, the transmission rod rotates automatically through the drive gear and rotating gear. This gear transmission method reduces dynamic load and achieves smooth transmission.

[0012] This high-speed precision gear transmission device for household steam cleaning appliances works as follows: During daily use, the operator starts the regulating motor, which causes the lead screw to rotate. The lead screw then drives the lead sleeve to slide inside the slotted groove. The lead sleeve then drives the moving plate to slide, which in turn drives the connecting rod to slide. The connecting rod then drives the slider to slide inside the slide groove. Simultaneously, the moving plate drives the locking rod to slide until the locking rod reaches the locking hole, thus locking the rotating gear and preventing accidental rotation when not in operation, thereby improving its stability.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0016] Please see Figures 1-5A high-speed precision gear transmission device for household steam cleaning appliances includes a housing 1. Heat dissipation grooves 2 are equidistantly spaced at both ends of the housing 1. A circular groove 3 is formed at the bottom interior of the housing 1. A circular rod 4 is rotatably mounted inside the circular groove 3. A drive gear 5 is fixedly mounted on the top of the circular rod 4. A rotating gear 6, located to the right of the drive gear 5, is rotatably mounted at the bottom interior of the housing 1. The outer surface of the rotating gear 6 meshes with the outer surface of the drive gear 5. A transmission rod 7 is rotatably mounted at the bottom of the housing 1. The top of the transmission rod 7 passes through the housing 1 and is fixedly connected to the bottom of the rotating gear 6. A driven belt is rotatably mounted at the top of the housing 1. The drive pulley 9, located to the right of the driven pulley 8, is rotatably mounted on the top of the housing 1. A transmission belt 10 is movably mounted on the outer surface of the driven pulley 8 and the outer surface of the drive pulley 9. A rotating rod 11 is fixedly mounted on the top of the drive gear 5. The top of the rotating rod 11 passes through the housing 1 and is fixedly connected to the bottom of the driven pulley 8. A rotary motor 12 is fixedly mounted on the top of the inside of the housing 1. The output end of the rotary motor 12 passes through the housing 1 and is fixedly connected to the bottom of the drive pulley 9. A protective shell 13 is fixedly mounted on the top of the housing 1. Both ends of the protective shell 13 are provided with heat dissipation holes 14 at equal intervals.

[0017] In this invention, when the transmission rod 7 needs to be driven, the rotary motor 12 is started. The operation of the rotary motor 12 causes the drive pulley 9 to rotate, which in turn drives the transmission belt 10 to rotate. Subsequently, the transmission belt 10 drives the driven pulley 8 to rotate, which in turn drives the rotating rod 11 to rotate. The rotating rod 11 then drives the drive gear 5 to rotate, which in turn drives the round rod 4 to rotate inside the round groove 3. At the same time, the drive gear 5 drives the rotating gear 6 to rotate, which in turn drives the transmission rod 7 to rotate. Thus, the transmission rod 7 can be automatically rotated through the drive gear 5 and the rotating gear 6. This operation method uses gear transmission, thereby reducing dynamic load and achieving smooth transmission. Secondly, the rotary motor 12 generates heat during operation, which can be dissipated through the heat dissipation groove 2. The outer surfaces of the driven pulley 8, the drive pulley 9, and the transmission belt 10 are all rough, and they transmit power through friction. When they are running, they generate a lot of friction, which can be dissipated through the heat dissipation holes 14. Example 2:

[0018] Please see Figures 1-5A high-speed precision gear transmission device for household steam cleaning appliances, wherein a fixed rod 15 is fixedly installed at the bottom of the inner side of the housing 1, a strip groove 16 is opened inside the fixed rod 15, a lead screw 17 is rotatably installed inside the strip groove 16, a threaded sleeve 18 is threaded onto the surface of the lead screw 17, a movable plate 19 is fixedly installed on the top of the threaded sleeve 18, and a locking rod 20 is fixedly installed on one side of the movable plate 19. A fixed ring 21 is fixedly installed on the top of the rotating gear 6, and a locking hole 22 is opened around the surface of the fixed ring 21.

[0019] In this invention, when it is necessary to lock the rotating gear 6, the lead screw 17 will cause the lead sleeve 18 to slide inside the strip groove 16 when it rotates. The outer surface of the lead sleeve 18 and the inner surface of the strip groove 16 are both smooth, which allows the lead sleeve 18 to slide more smoothly inside the strip groove 16 and reduces the occurrence of jamming. At this time, the lead sleeve 18 will cause the moving plate 19 to slide, and then the moving plate 19 will cause the locking rod 20 to slide until the locking rod 20 reaches the inside of the locking hole 22, which can lock the rotating gear 6 and prevent the rotating gear 6 from rotating unexpectedly when it is not running, thereby improving its stability. Example 3:

[0020] Please see Figures 1-5 A high-speed precision gear transmission device for household steam cleaning appliances. An adjusting motor 23 is fixedly installed on one side of the fixed rod 15, and the output end of the adjusting motor 23 passes through the fixed rod 15 and is fixedly connected to one side of the lead screw 17. A crossbar 24 is fixedly installed at both ends of the bottom inside the housing 1. A sliding groove 25 is opened inside the crossbar 24. A slider 26 is movably installed inside the sliding groove 25. A connecting rod 27 is fixedly installed on the opposite side of the slider 26, and one end of the connecting rod 27 is fixedly connected to one end of the moving plate 19.

[0021] In this invention, when the adjusting motor 23 is running, it drives the lead screw 17 to rotate. The design of the adjusting motor 23 can improve the rotation efficiency of the lead screw 17, thereby improving the adjustment efficiency of the lead sleeve 18. When the moving plate 19 slides, it drives the connecting rod 27 to slide. Subsequently, the connecting rod 27 drives the slider 26 to slide inside the slide groove 25. The inner surface of the slide groove 25 and the outer surface of the slider 26 are both smooth, which can make the slider 26 slide more smoothly inside the slide groove 25 and reduce the occurrence of jamming. The design of the slide groove 25 and the slider 26 can make the sliding of the connecting rod 27 more stable.

[0022] Working principle: First, the operator starts the rotary motor 12. The operation of the rotary motor 12 causes the drive pulley 9 to rotate, which in turn drives the transmission belt 10 to rotate. Subsequently, the transmission belt 10 drives the driven pulley 8 to rotate, which in turn drives the rotating rod 11 to rotate. The rotating rod 11 then drives the drive gear 5 to rotate, which in turn drives the round rod 4 to rotate inside the round groove 3. Simultaneously, the drive gear 5 drives the rotating gear 6 to rotate, which in turn drives the transmission... When rod 7 rotates, the adjusting motor 23 is started. The operation of the adjusting motor 23 causes the lead screw 17 to rotate, which in turn causes the lead screw 17 to slide inside the slot 16. At this time, the lead screw 17 causes the sleeve 18 to slide inside the slot 16. The sleeve 18 then causes the moving plate 19 to slide, which in turn causes the connecting rod 27 to slide. Subsequently, the connecting rod 27 causes the slider 26 to slide inside the groove 25. At the same time, the moving plate 19 causes the locking rod 20 to slide until the locking rod 20 reaches the inside of the locking hole 22, thus locking the rotating gear 6.
