Ice shaver structure

Abstract

An ice shaver structure comprises an ice pawl drive rotation unit, an ice pawl lifting control unit, a shaving blade unit, and a braking device. During shaving, ice blocks are placed inside the shaver housing. When the motor is started, the motor of the ice pawl drive rotation unit drives the worm gear, causing the ice pawl to rotate in tandem. Simultaneously, the braking device stops the ice pawl lifting control unit, allowing the ice pawl to grip the ice block and rotate together while the worm gear slowly moves downwards. As the ice block passes the shaving blade unit, a thin layer of shaved ice is scraped off by the blade, falling through an opening and being collected by a pre-placed connecting basin below the opening. When the ice block is shaved to its lower limit, the worm gear contacts a control switch, de-energizing and stopping the motor. When the amount of shaved ice reaches the pre-estimated amount or the ice block is shaved to its lower limit, with the motor stopped, a slight force is applied to overcome the resistance of the braking device to turn the adjusting wheel of the ice pawl lifting control unit, causing the worm gear and ice pawl to move upwards and away from the shaver housing, thus completing the shaving process.

Description

[Technical Field]

[0001] This utility model relates to a structure for an ice shaver, particularly a household electric ice shaver that allows adjustment of the coarseness of the shaved ice and is intended for home use. [Background Technology]

[0002] An ice shaver primarily uses blades to scrape the surface of an ice block, creating a shaved ice layer. This shaved ice, combined with dried fruit or fresh fruit and sugar syrup, becomes a refreshing summer treat. This invention is designed for home use, allowing consumers to make their own refreshing ice treats at home. [Utility Model Content]

[0003] The main purpose of this utility model is to provide a household electric shaver that allows for adjustable shaved ice texture and is easy to operate.

[0004] The structure of this ice shaver mainly comprises: an ice cleaver disk drive and rotation unit, an ice cleaver disk lifting and control unit, a shaver blade unit, and a braking device. The ice cleaver disk drive and rotation unit has a worm gear connected to the center of the top surface of the ice cleaver disk. The worm gear has an axially extending recess at a position on its circumference. This recess allows a key to be inserted into the wheel hole of the end gear of a first gear set driven by a motor, enabling the motor to drive the worm gear and ice cleaver disk to rotate via the first gear set after startup. The crampon disc lifting control unit has a manually adjustable wheel installed on the outside of the ice shaver. The axle of the adjusting wheel is connected to a second gear set, and the tail gear of the second gear set meshes with a worm. When the motor drives the worm to rotate, a braking device keeps the tail gear stationary. While rotating, the worm can move downwards along with the tail gear until it reaches the lowest set position, at which point it touches a control switch, stopping the motor and the worm and crampon disc together. To move the crampon disc upwards, because the key of the end gear is embedded in an axially extending groove, it does not affect the upward linear displacement of the worm. Manually rotating the adjusting wheel can indirectly drive the tail gear to rotate, and the rotation of the tail gear can drive the worm to move upwards, causing the crampon disc to move upwards as well. The shaving unit is located on the bottom of a box that can hold ice blocks. This box can be attached to or detached from the machine body. When attached, the ice claw disc can be embedded inside the box and the ice claws hold the top surface of the ice block, causing the ice block to rotate as a whole. The shaving unit includes a shaving blade, a slanted slider, an external threaded rod, an internal threaded hole, and a knob. The bottom surface of the box body has a receiving chamber in which the slanted slider is installed. The bottom end of the shaving blade is fixed to an inclined surface of the slanted slider. The top end of the shaving blade extends perpendicularly to the inclined surface and can extend upward into the box body through an opening on the bottom surface of the box body. The slanted slider is located at the opposite end of the shaving blade and connects to one end of the external threaded rod. The internal threaded hole is fixed to the wall of the box body. The other end of the external threaded rod passes through the interior of the internal threaded hole and engages with the shaving blade before exiting the machine body and being fixed to the knob. Rotating the knob can adjust the depth of the shaving blade into the box body, thus adjusting the coarseness of the shavings. The braking device can intermittently brake the tail gear, so that the worm remains stationary while rotating and can move downwards along the tail gear.

[0005] The braking device has a coaxial wheel on the side of one of the gears in the second gear set; a brake pad is provided, which abuts against the wheel surface of the wheel; a connecting post extends upward from the center of the top of the brake pad; a rigid platform is fixed to the top surface of the connecting post; an internal threaded hole is provided inside the body above the platform, through which a bolt is inserted; when the bolt rotates in the forward direction, the bottom applies axial pressure to the platform; an opening is provided on the top cover of the body corresponding to the top of the bolt; a screwdriver is inserted through the opening and the bolt is rotated to adjust the contact tightness between the brake pad and the wheel.

[0006] The braking device is achieved by manually holding the adjusting wheel in place, thereby preventing the tail gear from moving.

[0007] A control switch is located on the side of the machine body where the worm gear moves down to its lowest position. When the worm gear moves down to its lowest position, it contacts the control switch, which then stops the motor.

[0008] With this setup, during shaved ice operation, ice blocks are placed inside the box, and the length of the shaver blades extending into the box is adjusted. When the motor is started, the motor of the rotating unit driven by the ice claw disc drives the first gear set and the worm gear, causing the ice claw disc to rotate in tandem. The ice claw disc grips the ice block and rotates together, while the worm gear slowly moves downwards simultaneously. As the ice block passes over the shaver blades, a thin layer of ice shavings is scraped off, and the shavings fall through the opening and are collected by a pre-placed connecting basin located below the opening. When the ice block is shaved to the lower limit, the worm gear contacts the control switch, stopping the motor. When the amount of shaved ice reaches the estimated amount or the ice block is shaved to the lower limit, with the motor stopped, a slight force is applied to overcome the resistance of the braking device and turn the adjusting wheel. This causes the second gear set to drive the tail gear to rotate, which in turn moves the worm gear and ice claw disc upwards away from the box, completing the shaved ice process.

Detailed Implementation Methods

[0035] Please see Figures 1-6 As shown, the ice shaver 1 of this utility model embodiment has a body 10 covering the components. The main components consist of an ice pawl disc drive rotation unit 20, an ice pawl disc lifting control unit 30, a shaver blade unit 40, and a braking device 50. Among them,

[0036] The crampon disc drives the rotating unit 20, such as Figure 5 , 6 As shown, it includes a motor 21, a first gear set 22, a worm gear 23, and a pawl disc 24. The shaft 210 of the motor 21 can drive the first gear set 22 to rotate. The first gear set 22 includes gears a2a, b2b, c2c, d2d, e2e, f2f, and g2g that mesh sequentially or coaxially. The g gear 22g finally meshes with a final gear 220, so that the motor 21 can drive the first gear set 22 and the final gear 220 to rotate. A key 222 protrudes from the wall of the wheel hole 221 of the final gear 220. The worm gear 23 passes through the hole of the wheel hole 221 and has an axially extending groove 230 at a position on its circumference. The groove 230 allows the key 222 of the final gear to be inserted, so that the final gear 220 can drive the worm gear 23 to rotate by the key 222. The top center of the crampon disc 24 is fixedly connected to the bottom end of the worm gear 23. After the motor 21 is started, it can transmit driving force through the first gear set 22 to drive the worm gear 23 and the crampon disc 24 to rotate. The bottom surface of the crampon disc 24 has crampons 240 protruding downwards to grip the top surface of the ice block.

[0037] Please refer to the crampon disc lifting control unit 30. Figures 5-9 As shown. A manually adjustable wheel 31 is provided outside the body 10. The axle 310 of the adjustable wheel 31 is connected to a second gear set 32. The second gear set 32 ​​drives the i gear 32i through the h gear 32h, and the i gear 32i drives the coaxial tail gear 320 to rotate. The tail gear 320 meshes with the worm 23. When the aforementioned motor 21 drives the worm 23 to rotate, the brake device 50 (described in detail below) presses against the ice cleat disc lifting control unit 30, fixing the tail gear 320 stationary. When the worm 23 is indirectly driven to rotate by the motor 21, it can move downwards along the stationary tail gear 320 until it moves to the lowest limit setting position. At this point, the worm 23 touches a control switch 33 fixed to the body 10 (e.g., ...). Figure 3 , 5 When the motor 21 stops (as shown in Figure 8), the worm gear 23 and the crampon disc 24 also stop. To move the crampon disc 24 upwards, since the key 222 of the end gear 220 is embedded in the recess 230, it does not affect the upward linear displacement of the worm gear 23. Therefore, manually rotating the adjusting wheel 31 (overcoming the resistance of the braking device 50) will drive the second gear set 32 ​​to indirectly drive the tail gear 320 to rotate. When the tail gear 320 rotates, it drives the worm gear 23 to move upwards and reset, causing the crampon disc 24 to move upwards as well. Figure 9 As shown.

[0038] The planer unit 40, such as Figure 1 ,2 and Figures 10-12 As shown, an ice block is placed on the bottom surface of a box 41, which can hold ice blocks. The box 41 can be combined with or separated from the machine body 10. When combined, the ice claw disc 24 can be embedded inside the box 41 and the ice claw 240 holds the top surface of the ice block, causing the ice block to rotate as a whole. The planer unit 40 is provided with a planer 42, a sliding block 43, an external thread bar 44, an internal thread hole 45, and a knob 46; the bottom surface of the box 41 is divided into a receiving chamber 410, and the sliding block 43 is installed in the receiving chamber 410. The bottom end of the planer 42 is fixed to a slope 430 of the sliding block 43; the top end of the planer 42 extends perpendicularly to the slope 430 and can extend upward into the box 41 through an opening 411 on the bottom surface of the box 41; the sliding block 43 is located at the opposite end of the planer 42, connecting one end of the external thread rod 44. The internal thread hole 45 is fixed to the wall of the housing 41. The other end of the external thread rod 44 passes through the interior of the internal thread hole 45 and meshes with it before protruding outside the machine body 10 and being fixed to the knob 46. The external thread rod 44 protrudes outward from the outer side of the outer section of the machine body 10 and is fitted with a compression spring 47. The two ends of the compression spring 47 abut against the outer wall of the machine body 10 and the knob 46, giving the knob 46 the force to pull the external thread rod 44 outward. Manually rotating the knob 46 can adjust the depth to which the external thread rod 44 pushes the inclined slider 43 to pull the planer 42 into the housing 41, thereby adjusting the coarseness of the shaved ice. Figure 12 Planer blade 42 extends a relatively long length Figure 12 The extra length is L.

[0039] The braking device 50 can be achieved by manually fixing the adjusting wheel 31 to hold the tail gear 320 stationary while the motor 21 drives the worm gear 23 to rotate. However, this method requires more effort from the operator. Alternatively, the structure of the braking device 50 can also be as follows: Figure 3 , 5As shown, in one of the gears of the second gear set 32 ​​(e.g., gear h 32h in the figure), a coaxial circular wheel 51 is provided on the side of the wheel; a brake pad 52 is provided, which abuts against the wheel surface of the circular wheel 51. A connecting post 520 extends upward from the middle of the top of the brake pad 52. A rigid platform 521 is fixed to the top surface of the connecting post 520. An internal threaded hole 53 is provided inside the body 10 above the platform 521. The internal threaded hole 53 allows a bolt 54 to pass through, and when the bolt 54 rotates in the forward direction, its bottom can apply axial pressure to the table surface 521. The top cover 11 of the machine body 10 has an opening 12 corresponding to the top of the bolt 54. A screwdriver can be inserted into the opening 12 to adjust the rotation of the bolt 54, thereby adjusting the contact tightness between the brake pad 52 and the wheel 51, and braking the wheel 51, the h gear 32h, and the tail gear 320. Therefore, when the motor 21 drives the worm 23 to rotate, because the tail gear 320 is stopped by the braking device 50, the worm 23 can not only rotate, but also move downwards along the stationary tail gear 320.

[0040] When applying:

[0041] Before shaving the ice, manually rotate knob 46 to adjust the extension length of the shaving blade 42 of the shaving unit 40 to adjust the coarseness of the shaved ice. Then, manually rotate adjustment wheel 31 to drive the second gear set 32, which in turn drives the tail gear 320. When the tail gear 320 rotates, it drives the worm gear 23 to move upwards, causing the ice claw disc 24 to move upwards as well, and thus lifting the ice claw disc 24 away from the housing 41. Figure 9 As shown. Then, remove the box 41, put the ice brick into the box 41, and then hold the box 41 and connect it to the main body 10.

[0042] The motor 21 is started, and at the same time, the braking device 50 keeps the tail gear 320 stationary due to braking. In this situation, the worm gear 23, in addition to being indirectly driven to rotate by the motor 21, can also move axially downward with the stationary tail gear 320 as the meshing fulcrum, driving the ice claw disc 24 downward and causing the ice claw 240 to engage with the top surface of the ice block, causing the ice block to rotate together, while the worm gear 23 slowly moves downward. When the bottom surface of the ice block passes the planer 42, a thin layer of ice shavings will be scraped off by the planer 42, and the ice shavings will fall from the opening 411 and be received by the connecting basin located below the opening 411.

[0043] When the ice block is shaved to the lower limit, the worm gear 23 will contact the control switch 33 (e.g., Figure 8As shown, the control motor 21 is powered off and stopped; when the amount of ice shaved reaches the estimated amount or the ice block is shaved to the lower limit, with the motor 21 stopped, slightly force is applied to overcome the resistance of the brake device 50 to rotate the adjusting wheel 31, so as to drive the tail gear 320 to rotate, which in turn drives the worm 23 and the ice claw plate 24 to move upward and reset in the opposite direction, leaving the box 41, thus completing the ice shaving process.

[0044] If the braking resistance of the brake pads 52 of the aforementioned braking device 50 to the wheel 51 is too low due to wear, it can be adjusted by turning the bolt 54 through the opening 12 with a screwdriver.
