This application claims priority to Chinese Patent Application No. 202322665631.2, filed on Oct. 7, 2023, which is hereby incorporated by reference in its entirety.
The present disclosure relates to the field of children's toys technologies, and in particular, to an improved transmission structure for a mini bubble machine.
At present, automatic bubble blowing machines on the market require providing transmission gears and shafts to separately transmit to impellers and bubble-forming components for the impeller and bubble-forming components in bubble blowing components. This results in the use of a large number of transmission gears, renders the overall volume of the bubble machine to be large and cumbersome when playing by children, which has poor less portability.
Publication No. of CN216629660U, entitled with a tooth box structure for a bubble machine, discloses a tooth box structure for a bubble machine. Although an impeller is connected to a transmission shaft of a transmission motor, which saves a certain amount of transmission gear and space, the bubble-forming component requires a large number of transmission gears and a transmission shaft is provided at an upper end, which is matched with transmission teeth provided around the bubble-forming component to achieve a rotation of the bubble-forming component. This layout greatly occupies the space of the transmission structure, and due to the need to provide transmission teeth around the bubble-forming component, it cannot be made thin for stable transmission. The weight increases and occupies space.
The purpose of the present disclosure is to provide a transmission structure for a mini bubble machine in response to the shortcomings of existing technology, and to solve a problem of the existing bubble machine transmission structure occupying a large space, which results in large volume, heavy weight, and poor portability of the blowing bubble toys.
The technical solution adopted by the present disclosure to achieve the above objectives is as following.
A transmission structure for a mini bubble machine, including a shell, a bubble blowing component provided at a front end of the shell, and a transmission mechanism that is connected to a rear end of the bubble blowing component; the transmission mechanism include a drive motor and a transmission shaft component connected to the drive motor; a front end of the transmission shaft component is connected to the bubble blowing component, the bubble blowing component is driven to work by the drive motor through driving the transmission shaft component.
The drive motor is located at an upper end of the transmission shaft component, a liquid adding component that is connected to the transmission shaft component is provided at a lower end of the transmission shaft component; the bubble blowing component includes an impeller, an air guide member, and a bubble-forming component.
The transmission shaft component is a shaft-to-shaft structure.
The transmission shaft component includes a first transmission gear fixedly connected to the impeller at a front end and driving the impeller to rotate synchronously, a support member provided at a rear end of the first transmission gear, and a bubble-forming component transmission shaft axially provided at a center of the support member, first transmission gear, impeller, and air guide member; the bubble-forming component transmission shaft penetrates the support member, first transmission gear, impeller, and air guide member; a front end of the bubble-forming component transmission shaft is fixedly at a center of the bubble-forming component; a second transmission gear is fixedly fixed at a rear end of the bubble-forming component transmission shaft, the second transmission gear is connected to the liquid adding component; the second transmission gear drives the bubble-forming component transmission shaft to rotate, thereby driving the bubble-forming component to work.
An impeller transmission shaft is sleeved on the bubble-forming component transmission shaft and which is movably connected to the bubble-forming component transmission shaft; a rear end of the impeller transmission shaft is provided in the support member, a front end of the impeller transmission shaft is provided in a center of the air guide member, the first transmission gear and impeller are fixed on the impeller transmission shaft.
The liquid adding component includes an liquid adding wheel, a first reversing tooth is provided at a rear end of the first transmission gear, a power input end of the liquid adding wheel is connected to the first reversing tooth through a third transmission gear; an power output end of the liquid adding wheel is connected to the second transmission gear through a fourth transmission gear, a second reversing tooth is provided at a rear end of the fourth transmission gear; the fourth transmission gear is connected to the second transmission gear through the second reversing tooth.
A liquid adding pipe extrusion wheel is provided on the liquid adding wheel.
The beneficial effect of the present disclosure is that the transmission structure for the mini bubble machine of the present disclosure adopts a shaft-to-shaft transmission structure for the impeller and bubble-forming component, thereby solving the problem of large volume of the bubble machine caused by the large space of the traditional bubble machine transmission structure due to the proving of more transmission gears and external transmission shafts. Due to the use of the shaft-to-shaft transmission structure of the present disclosure, the transmission mode of the bubble-forming component is changed from a transmission of gear connected to other transmission shaft to a shaft-to-shaft transmission, thereby achieving the bubble-forming component can be thin, further reducing space occupancy, and reducing the weight of the bubble machine.
