Description

Technical Field

[0001] This utility model belongs to the technical field of food processing machines, and relates to a food dehydrator. Background Technology

[0002] After washing vegetables, they are usually placed in a draining basket for automatic drainage. However, this method is time-consuming and not very effective. To quickly drain vegetables, the current trend is to use a food dehydrator. A food dehydrator generally includes a base, a mesh basket, a lid, and a top cover. In use, the vegetables are placed in the mesh basket, and the lid is rotated by a press-type drive component on the top cover. The lid rotates the mesh basket, and the centrifugal force generated by the rotation of the mesh basket throws the water out of the vegetables and separates it into the base, thus dehydrating the vegetables.

[0003] After the basket is dehydrated by rotation, the vegetables can only be taken out after the rotation stops. This process is very long. Therefore, it is necessary to install a braking device in the dehydrator so that the rotating basket can be stopped quickly.

[0004] Chinese invention patent CN103391739A (publication date: 2013.11.13) discloses an improved braking mechanism for a device for drying food and other articles. The device for drying food includes: a container comprising a bowl having sidewalls terminating at an edge defining an opening, and a lid detachably connected to the bowl and covering the opening; a basket assembly located within the bowl and rotatable relative to the container about a rotation axis, the basket assembly including a basket having perforated sidewalls terminating at a top edge, and a lid detachably connected to the basket. The cover has a top edge; an upright annular ridge extending from the top surface of the cover toward the cover, the annular ridge being coaxially arranged about the axis of rotation; and a braking assembly including a braking button supported by the cover, wherein the braking button is operatively connected to a clamping arm extending parallel to the axis of rotation and movable between a non-braking position and a braking position, wherein the clamping arm frictionally engages with the annular ridge when the braking button is translated relative to the cover, and wherein the clamping arms retract toward each other when the clamping arm moves toward the braking position.

[0005] The aforementioned dehydrator brakes the cap by clamping arms that contract with each other. The main source of its braking force is the force generated by the deformation of the clamping arms, which is very limited and cannot brake the cap quickly. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by providing a food dehydrator with the advantages of simple structure and rapid braking.

[0007] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

[0008] A food dehydrator includes a base, a mesh basket, a cover, and a top cover. The top cover is equipped with a drive assembly for rotating the cover. The cover is circumferentially fixed to the mesh basket, and rotating the cover causes the mesh basket to rotate synchronously. The top of the cover has a coaxial convex ring, and the bottom of the top cover has a braking assembly. The braking assembly includes a brake seat, a brake button, a slider, and a brake block. The slider slides radially on the brake seat, and the bottom of the slider extends below the brake seat and connects to the brake block. The brake button drives the slider and the brake block to slide inward. When the brake block slides to contact the outer side of the convex ring, it brakes the cover.

[0009] In the aforementioned food dehydrator, the top cover is provided with a mounting cavity, the bottom of the mounting cavity is provided with a mounting through hole, the brake button slides axially within the mounting cavity and its bottom passes through the mounting through hole and extends downward, the bottom of the brake button and the top of the slider are provided with cooperating drive slopes, when the brake button slides downward, the drive slope drives the slider to slide inward; specifically, the drive slope is inclined from top to bottom outward.

[0010] In the aforementioned food dehydrator, the structure of the brake button driving the slider can also be configured in other ways, such as the brake button abutting against the outer side of the slider, and the slider being driven to slide inward by radially sliding the brake button.

[0011] In the aforementioned food dehydrator, the brake seat is provided with a radial groove for the slider to slide, and the bottom of the brake seat is provided with a side sliding groove for the slider to extend and slide, and an axial groove for the brake button to slide; the middle of the slider is provided with a drive groove that cooperates with the brake button, and the drive inclined surface is provided on the inner side of the drive groove.

[0012] In the aforementioned food dehydrator, a radial limiting block extending upward to the drive channel is provided on the rear side of the axial through groove of the brake seat. When the inner side of the radial limiting block abuts against the inner side of the drive channel, a radial limiting structure is formed.

[0013] In the aforementioned food dehydrator, a radial return spring for driving the slider to reset is provided between the slider and the brake seat, and an axial return spring for driving the brake button to reset is provided between the brake button and the bottom of the mounting cavity.

[0014] In the aforementioned food dehydrator, limit through holes are provided on both sides of the mounting through hole, and axial limit blocks are provided on both sides of the brake button, which pass through the limit through holes. An axial limit clamp is provided at the bottom of the axial limit block to abut against the bottom of the top cover for limitation.

[0015] In the aforementioned food dehydrator, the bottom of the top cover is provided with a mounting base that cooperates with the brake seat. The brake seat is detachably connected to the mounting base by fasteners, and the mounting base and the brake seat form a closed cavity for accommodating the slider.

[0016] In the aforementioned food dehydrator, the brake block is connected to the inner side of the slider, and the inner side of the brake block is provided with an arc-shaped surface that matches the outer side of the convex ring.

[0017] In the aforementioned food dehydrator, the brake block is made of a flexible material, and a plurality of connectors are provided at one end of the brake block opposite to the slider. The bottom of the slider is provided with a connecting cavity that mates with the connectors, and the bottom of the slider is provided with a fixing plate that closes the connecting cavity and fixes the brake block. The fixing plate is fixedly connected to the slider through a snap-fit ​​structure or a column hole structure.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] This invention provides a food dehydrator with an improved braking structure. The brake button directly drives the slider and brake block to move radially, and the brake block acts on the sealing ring to produce a braking effect. The braking structure of this invention can directly transmit the force applied by the operator to the brake block and act on the sealing ring. The braking force can increase with the increase of the applied force. At the same time, the braking effect can be further improved by using the brake block that can generate sufficient friction.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-6 :

[0028] A food dehydrator includes a base basin 1, a mesh basket 2, a cover 3, and a top cover 4. The top cover 4 is provided with a drive assembly 5 for driving the cover 3 to rotate. The cover 3 is circumferentially fixed to the mesh basket 2. When the cover 3 rotates, it drives the mesh basket 2 to rotate synchronously. The top of the cover 3 is provided with a coaxial convex ring 6. The bottom of the top cover 4 is provided with a braking assembly. The braking assembly includes a brake seat 7, a brake button 8, a slider 9, and a brake block 10. The slider 9 slides radially on the brake seat 7. The bottom of the slider 9 extends below the brake seat 7 and connects to the brake block 10. The brake button 8 drives the slider 9 and the brake block 10 to slide inward. When the brake block 10 slides to contact the outer side of the convex ring 6, it brakes the cover 3.

[0029] Comparison Appendix Figure 1 and attached Figure 2 The dehydration method in this embodiment is the same as that of existing dehydrators, and will not be described again here. The braking method in this embodiment is as follows: Pressing the brake button 8 drives the slider 9 to move inward, and the brake block 10 moves inward synchronously until the brake block 10 contacts the outer side of the convex ring 6. The contact surface between the brake block 10 and the outer side of the convex ring 6 generates a frictional force that resists the rotation of the cover 3, and this force increases rapidly with the continued pressing, causing the cover 3 to stop quickly, and the basket 2 to stop rotating.

[0030] Comparison Appendix Figure 5 and attached Figure 6In this embodiment, the specific structure of the brake button 8 driving the slider 9 is as follows: the top cover 4 is provided with a mounting cavity 11, the bottom of the mounting cavity 11 is provided with a mounting through hole 12, the brake button 8 slides axially in the mounting cavity 11 and the bottom passes through the mounting through hole 12 and extends downward, the bottom of the brake button 8 and the top of the slider 9 are provided with cooperating driving inclined surfaces 13, when the brake button 8 slides downward, the driving inclined surface 13 drives the slider 9 to slide inward; specifically, the driving inclined surface 13 is inclined outward from top to bottom, when the brake button 8 is pressed, the brake button 8 generates axial displacement along the mounting cavity 11, since the slider 9 can only move radially and cannot move axially, the interaction between the driving inclined surfaces 13 causes the slider 9 to move inward.

[0031] Furthermore, in order to facilitate the sliding action, the brake seat 7 is provided with a radial groove 14 for the slider 9 to slide, and the bottom of the brake seat 7 is provided with a side sliding groove 15 for the slider 9 to extend and slide, and an axial groove 16 for the brake button 8 to slide; the middle of the slider 9 is provided with a drive groove 17 that cooperates with the brake button 8, and the drive inclined surface 13 is provided on the inner side of the drive groove 17.

[0032] Furthermore, a radial limiting block 18 extending upward to the drive through groove 17 is provided on the rear side of the axial through groove 16 of the brake seat 7. When the inner side of the radial limiting block 18 abuts against the inner side of the drive through groove 17, a radial limiting structure is formed.

[0033] This embodiment also provides a reset structure for the braking assembly. A radial reset spring 19 is provided between the slider 9 and the brake seat 7 to drive the slider 9 to reset. When the slider 9 moves inward, the radial reset spring 19 is compressed. After the brake button 8 is released, the radial reset spring 19 drives the slider 9 to reset outward. An axial reset spring 20 is provided between the brake button 8 and the bottom of the mounting cavity 11 to drive the brake button 8 to reset. When the brake button 8 is pressed down, the axial reset spring 20 is compressed. After the brake button 8 is released, the axial reset spring 20 drives the brake button 8 to reset upward.

[0034] Comparison Appendix Figure 3 and attached Figure 4 To prevent the brake button 8 from coming off, limit holes 21 are provided on both sides of the mounting through hole 12, and axial limit blocks 22 are provided on both sides of the brake button 8, which pass through the limit holes 21. An axial limit clip 23 is provided at the bottom of the axial limit block 22 to abut against the bottom of the top cover 4.

[0035] Comparison Appendix Figure 4 The bottom of the top cover 4 is provided with a mounting base 24 that cooperates with the brake seat 7. The brake seat 7 is detachably connected to the mounting base 24 by fasteners. The mounting base 24 and the brake seat 7 form a closed cavity for accommodating the slider 9.

[0036] To increase the contact area during braking, the brake block 10 is connected to the inner side of the slider 9, and the inner side of the brake block 10 is provided with an arc-shaped surface that matches the outer side of the convex ring 6.

[0037] Preferably, the brake block 10 is made of a flexible material. A plurality of connectors 25 are provided at the end of the brake block 10 opposite to the slider 9. A connecting cavity 26 that mates with the connectors 25 is provided at the bottom of the slider 9. A fixing plate 27 that closes the connecting cavity 26 and fixes the brake block 10 is provided at the bottom of the slider 9. The fixing plate 27 is fixedly connected to the slider 9 via a snap-fit ​​structure or a post-hole structure. The elastic deformation of the brake block 10 generates sufficient braking friction between the brake block 10 and the convex ring 6. Furthermore, the greater the force applied to pressing the brake button 8, the greater the deformation of the brake block 10, thereby generating even greater friction.

[0038] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
