Referring to the drawings and initially to Figs. 1-6, a drive mechanism for a dehydrator in accordance with the preferred embodiment of the present invention comprises a housing 20, a base 10 located under the housing 20, a rotation barrel 21 rotatably mounted in the housing 20 to receive an article, such as a mop head and the like, a driven member 12 rotatably mounted between the base 10 and the housing 20, a propeller shaft 121 having a first end secured on and rotated by the driven member 12 and a second end extending through the housing 20 and secured to the rotation barrel 21 to rotate the rotation barrel 21, a drive member 11 rotatably mounted between the base and the housing 20 and engaging the driven member 12 to rotate the driven member 12, a worm 111 secured on the drive member 11 to rotate the drive 10 member 11, an actuating member 13 movably mounted on the worm 111 and having an inner portion provided with a worm hole 131 meshing with the worm 111 to rotate the worm 111 by axially moving the actuating member 13 relative to the worm 111, a pedal 15 pivotally mounted on the base 10 and connected with the actuating member 13 to move the actuating member 13 relative to the worm 111 axially, and an elastic member 14 mounted on the worm 111 and pressing the actuating member 13 to move the actuating member 13 relative to the worm 111.
The drive member 11 is a gear, and the driven member 12 is a gear.
The drive member 11 has a diameter greater than that of the driven member 12.
The propeller shaft 121 is co-axial with the driven member 12, and the worm 111 is co-axial with the drive member 11. The propeller shaft 121 is located between the housing 20 and the base 10. The worm 111 is located between the housing 20 and the base 10. The elastic member 14 is biased between the actuating member 13 and the housing 20 to move the actuating member 13 toward the drive member 11. The actuating member 13 has two opposite sides each provided with a protruding pivot rod 132. The pedal 15 has an end portion provided with a pivot portion 151 pivotally connected with the actuating member 13 to move the actuating member 13 outwardly relative to the drive member 11. The pivot portion 151 of the pedal 15 has a substantially U-shaped profile and has an opening to receive the actuating member 13. The pivot portion 151 of the pedal 15 has two opposite sides each provided with an elongate pivot slot 152 pivotally mounted on the respective pivot rod 132 of the actuating member 13.
The drive mechanism further comprises a pivot seat 16 mounted on the base 10, and the pedal 15 is pivotally mounted on the pivot seat 16 by a pivot pin 162. The pivot seat 16 consists of two upright support plates spaced from each other. The pivot seat 16 has two opposite sides each provided with a through hole 161 to allow passage of the pivot pin 162. The pedal 15 is sandwiched between the two support plates of the pivot seat 16 and has a mediate portion provided with a pivot hole 153 pivotally mounted on the pivot pin 162.
In operation, referring to Figs. 3-6 with reference to Figs. 1 and 2, when the pedal 15 is stepped downward as shown in Figs. 5 and 6, the pivot portion 151 of the pedal 15 is moved upward to move the actuating member 13 upward relative to the worm 111 and to compress the elastic member 14. At this time, the worm hole 131 of the actuating member 13 meshes with the worm 111 so that when the actuating member 13 is moved upward relative to the worm 111, the worm 111 is driven and rotated by the worm hole 131 of the actuating member 13 to rotate the drive member 11 which rotates the driven member 12 which rotates the propeller shaft 121 which drives the rotation barrel 21 to rotate in the housing 20. On the contrary, when the stepping force applied on the pedal 15 is removed, the actuating member 13 is driven by the restoring force of the elastic member 14 to move downward relative to the worm 111 as shown in Figs. 3 and 4. At this time, the worm hole 131 of the actuating member 13 meshes with the worm 111 so that when the actuating member 13 is moved downward relative to the worm 111, the worm 111 is driven by the worm hole 131 of the actuating member 13 to rotate in the opposite direction and to rotate the drive member 11 which rotates the driven member 12 which rotates the propeller shaft 121 which drives and rotates the rotation barrel 21 in the opposite direction. The above-mentioned procedures are repeated successively so that the rotation barrel 21 is rotated reciprocally to spin the mop head rightward and leftward so as to dry the mop head.
Accordingly, the drive member 11 has a diameter greater than that of the driven member 12 so that the drive member 11 has a larger transmission power to drive the driven member 12 efficiently so as to rotate the rotation barrel 21 and to dry the mop head easily and quickly. In addition, the drive member 11 has a diameter greater than that of the driven member 12 so that the user can operate the pedal 15 easily and conveniently so as to drive the drive member 11 in an energy-saving manner. Further, the drive mechanism has a greatly simplified construction, thereby decreasing the cost of fabrication.
Referring to Figs. 7-10, the elastic member 14 is biased between the actuating member 13a and the base 10 to move the actuating member 13a outwardly relative to the base 10. The base 10 has a surface provided with a fixing hole 101 to fix a lower end of the propeller shaft 121. The actuating member 13a abuts a bottom of the pedal 15a and has two bent resting portion 132a abutting two opposite sides of the pedal 15a. The pedal 15a has a mediate portion provided with an elongate guide slot 156a to allow passage of the worm 111. The drive mechanism further comprises a pivot seat 16a mounted on the base 10, and the pedal 15a has an end portion provided with a pivot portion 151a pivotally mounted on the pivot seat 16a by a pivot pin 162a. The pivot seat 16a has an upper end provided with a transverse through hole 161a to allow passage of the pivot pin 162a. The pivot seat 16a has a side provided with two reinforcing plates 163a each abutting a top of the base 10. The pivot portion 151a of the pedal 15a has a substantially U-shaped profile and has an opening 155a to receive the pivot seat 16a and to allow passage of the propeller shaft 121. The pivot portion 151a of the pedal 15a has two pivot holes 154a pivotally mounted on the pivot pin 162a.
