Peristaltic Pump U-Shaped Transmission Layout for Compact E-Cigarettes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peristaltic pumps in e-cigarettes have a large volume due to the arrangement of gear sets in a deceleration box, leading to increased product size, manufacturing costs, and inconvenience in use and carrying.
Innovation Solution
A peristaltic pump design with a carrier, drive assembly, transmission assembly, and peristaltic assembly arranged in a U-shape, utilizing two accommodating spaces to integrate and compactly arrange transmission shafts and gears, reducing the need for a conventional deceleration outer box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a conventional deceleration box with multiple gear sets is used, then the deceleration function is achieved, but the volume of the decelerator and final product increases
Solution Approach 1:
The patent combines multiple gear sets (first, second, and third gear sets) into a single integrated deceleration box structure, where gears from different stages are arranged within the same housing space. This merging approach eliminates the need for separate deceleration boxes for each gear stage, thereby achieving the required deceleration function while reducing the overall volume of the decelerator.
2Power
If the volume of the decelerator is increased to accommodate multiple gear sets, then the deceleration function is maintained, but the volume of the final product increases
Solution Approach 1:
The patent integrates multiple gear sets into a single deceleration box, which is then installed within the pump head assembly. This merging strategy allows the decelerator to occupy space within the existing pump head volume rather than adding external volume, thereby maintaining the deceleration function while avoiding an increase in the final product volume.
3Reliability
If an external motor outer cover is used to house the motor and deceleration apparatus, then the components are protected, but the overall product volume increases
Solution Approach 1:
The patent combines the motor and deceleration apparatus into a single integrated assembly where the motor is directly coupled to the deceleration box. This merged configuration allows both components to share the same space within the pump head, eliminating the need for a separate external motor outer cover and thereby reducing the overall product volume while maintaining component protection.
4Power
If multiple gear sets are arranged in separate deceleration boxes, then each gear set functions independently, but the device complexity increases
Solution Approach 1:
The patent merges multiple gear sets into a single deceleration box with a unified structure. The first, second, and third gear sets are arranged within the same housing, sharing common mounting features and support structures. This integration reduces the number of separate components and assembly steps, thereby decreasing device complexity while maintaining the independent functionality of each gear set.

AI summary
The present invention discloses an electronic cigarette and a peristaltic pump thereof, the peristaltic pump including a carrier, a drive assembly, a transmission assembly, and a peristaltic assembly. The drive assembly is arranged on the carrier, the peristaltic assembly and the drive assembly are arranged side by side on the same side of the carrier, a first accommodating space is provided between the drive assembly and the carrier, a second accommodating space is provided between the peristaltic assembly and the carrier, the transmission assembly is respectively disposed in the first accommodating space and the second accommodating space, and the drive assembly is connected to the peristaltic assembly through the transmission assembly. The transmission assembly is respectively in the first accommodating space and the second accommodating space, to further connect the drive assembly to the peristaltic assembly. The transmission assembly, the drive assembly, and the peristaltic assembly are all arranged on the carrier, and are entirely in a shape of "U". Therefore, not only the first accommodating space and the second accommodating space are appropriately utilized, but also a conventional deceleration outer box is reduced. In addition, the arrangement of the transmission assembly is more compact, an effect of volume reduction is achieved, and the volume of a final product is also reduced, which is convenient for carrying and use.
