Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a braking device for a dehydrator. Background Technology

[0002] A salad spinner, as a kitchen appliance, is mainly used to dehydrate washed fruits and vegetables. The structure of a salad spinner typically includes an outer shell, a top cover, a spin-drying basket, and a drive unit. The top cover fits onto the outer shell, the spin-drying basket is located inside the shell, and the drive unit is installed on the top cover and connected to the spin-drying basket. The user operates the drive unit to rotate the spin-drying basket, thus dehydrating the fruits and vegetables inside.

[0003] When the user needs to remove the dehydrated fruits and vegetables from the dehydration basket, the basket should be stopped rotating. For this purpose, salad spinners are usually equipped with a brake device so that the user can brake the basket as needed.

[0004] In the prior art, salad spinners typically employ a push-button brake structure. For example, a hand-cranked spinner disclosed in Chinese invention patent application (publication number CN101598488A) uses a braking device consisting of a fixed mounting plate, a brake button, and a brake caliper. During the rotation of the spinner basket, pressing the brake button opens the through hole at the rear end of the brake caliper, causing the front end of the caliper to move towards the center. This causes the wear-resistant lining of the spinner to press against the edge of the one-way turntable, braking the one-way turntable and stopping the spinner basket, which rotates synchronously with the one-way turntable, thus achieving the purpose of braking.

[0005] However, for dehydrators equipped with a button-type brake, when braking, the fingertip (or fingertip) needs to be aligned with the brake button and pressed down by the fingertip, which makes operation inconvenient.

[0006] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0007] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a braking device for a dehydrator, which has a simple and reasonable structure and is easy to operate.

[0008] To achieve the above objectives, the present invention adopts the following technical solution.

[0009] A braking device for a dehydrator, comprising:

[0010] The base defines the mounting position of the braking device;

[0011] A one-way turntable rotates in one direction under the drive of a drive device, and drives the dehydration basket of the dehydrator to rotate synchronously.

[0012] The braking device includes:

[0013] A hand-operated brake assembly is provided, which engages with the one-way turntable. The hand-operated brake assembly is movably disposed relative to the base. The hand-operated brake assembly extends to include a brake operating portion. The base is provided with a base operating portion corresponding to the brake operating portion.

[0014] In single-handed operation, the brake operating part and the base operating part can be moved away from and closer to each other by pinching and opening the fingers, thereby driving the hand-operated brake to move relative to the base:

[0015] When the brake operating part approaches the base operating part, the hand-squeezed brake component brakes the one-way turntable.

[0016] When the brake operating part moves away from the base operating part, the hand-operated brake releases the brake on the one-way turntable.

[0017] Furthermore, both the brake operating part and the base operating part are located on the upper surface of the base.

[0018] Furthermore, both the brake operating part and the base operating part extend laterally along the upper surface of the base.

[0019] Furthermore, the upper surface of the base has a stepped groove that provides the necessary space for the brake operating part to move. The base operating part is a protruding ridge formed on the upper surface of the base, and one side surface of the base operating part defines the first side wall of the stepped groove.

[0020] Furthermore, there is always an operating gap between the second side wall of the stepped groove, which is away from the first side wall, and the brake operating part.

[0021] Furthermore, the braking device also includes a turntable brake component, which is a friction ring fixedly sleeved on the one-way turntable, and the hand-operated brake component is provided with a brake protrusion that engages with the friction ring.

[0022] Furthermore, the base includes an upper cover and a sealing cover, the upper cover and the sealing cover are fixedly connected and cooperate to form a receiving cavity, the hand-operated brake is disposed in the receiving cavity, the upper cover is provided with a notch for the brake operating part to extend from the receiving cavity, and the base operating part is located on the side of the notch.

[0023] Furthermore, the hand-operated brake is horizontally rotatably disposed within the accommodating cavity. When the brake operating part and the base operating part move away from or closer to each other, the hand-operated brake swings relative to the base along with the brake operating part.

[0024] Furthermore, an elastic element is provided inside the accommodating cavity, which ensures that the hand-operated brake component always has a tendency to release the brake on the one-way turntable.

[0025] Furthermore, the elastic element is an elastic sheet, a positioning post is provided in the accommodating cavity, one end of the elastic element is connected to the hand-operated brake element, and the other end of the elastic element abuts against the positioning post.

[0026] The beneficial effects of this utility model are as follows:

[0027] This utility model provides a braking device for a dehydrator. By extending a brake operating part from a hand-operated brake component and setting a base operating part corresponding to the brake operating part on the base, the brake operating part and the base operating part cooperate with each other, so that the brake operating part and the base operating part can be controlled to move away from each other and move closer together under one-handed operation, thereby driving the hand-operated brake component to move relative to the base, thereby realizing braking control of the one-way turntable and the dehydration basket.

[0028] Compared to the button-type brake structure in the prior art, the brake device for a dehydrator provided by this utility model allows the user to manually engage and disengage the dehydration basket by applying a portion of the fingers of their dominant hand to the brake operating part and the remaining fingers of the same hand to the base operating part. This manual squeezing and disengaging action moves the brake operating part and the base operating part closer and further apart. This achieves braking control of the dehydration basket. This hand-squeezed brake structure is not only simple and reasonable in design, but also convenient and labor-saving to operate. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] like Figures 1 to 3 The braking device of a salad dehydrator shown includes a base 1, which provides the necessary installation space for the braking device to define its installation position. In a specific embodiment, the base 1 is a component of the salad dehydrator and is mounted to the outer shell 2 of the salad dehydrator.

[0035] The salad dehydrator also includes a one-way turntable 3, which is connected to the dehydration basket 4. The one-way turntable 3 rotates in one direction under the drive of the dehydrator's drive device, and drives the dehydration basket 4 of the dehydrator to rotate synchronously, thereby enabling the salad dehydrator to perform dehydration operations. When the salad dehydrator is performing dehydration operations, the base 1 and the outer shell 2 remain relatively stationary.

[0036] See Figure 1 and Figure 2 The braking device includes a hand-operated brake 5, which engages with a one-way turntable 3 for braking. The hand-operated brake 5 is movably disposed relative to the base 1. The hand-operated brake 5 extends to a brake operating part 51. The base 1 is provided with a base operating part 111 corresponding to the brake operating part 51. With the base 1 as a reference, under the action of an external force, the brake operating part 51 can move closer to and further away from the base operating part 111. During the relative movement of the two, the hand-operated brake 5 moves synchronously with the brake operating part 51.

[0037] In a specific embodiment, the maximum distance between the brake operating part 51 and the base operating part 111 is within the range that an ordinary adult can reach with one hand. That is, the user can move the brake operating part 51 and the base operating part 111 away from each other and move closer to each other by pinching and opening the fingers under one-handed operation, so as to drive the hand-squeezed brake 5 to move relative to the base 1: when the brake operating part 51 is close to the base operating part 111, the hand-squeezed brake 5 brakes the one-way turntable 3, at which time the dehydration basket 4 stops rotating; when the brake operating part 51 is away from the base operating part 111, the hand-squeezed brake 5 releases the brake on the one-way turntable 3, at which time the dehydration basket 4 can rotate under the drive of the drive device.

[0038] Preferably, for ease of braking control by the user, see [reference needed]. Figure 1 Both the brake operating part 51 and the base operating part 111 are located on the upper surface of the base 1. Furthermore, both the brake operating part 51 and the base operating part 111 extend laterally along the upper surface of the base 1, so that when the salad spinner is placed on the kitchen countertop, the user can more easily access the brake operating part 51 and the base operating part 111 to perform braking operations.

[0039] In this embodiment, see Figure 1 and Figure 2 The upper surface of the base 1 has a stepped groove 112 that provides the necessary movement space for the brake operating part 51. The base operating part 111 is a raised ridge formed on the upper surface of the base 1. One side surface of the base operating part 111 defines a first side groove wall 1121 of the stepped groove 112. There is always an operating gap 113 between the second side groove wall 1122 of the stepped groove 112, which is away from the first side groove wall 1121, and the brake operating part 51. The operating gap 113 ensures that the user's fingers can always easily reach the brake operating part 51.

[0040] The stepped groove 112 provides the space required for the movement of the brake operating part 51. Taking a right-handed user as an example, when operating, the user can touch the brake operating part 51 with their thumb and touch the base operating part 111 with their remaining four fingers. By pinching and opening the fingers, the brake operating part 51 and the base operating part 111 move closer and further apart, thereby performing braking control.

[0041] In this embodiment, see Figure 2 The braking device also includes a rotary brake component 6, which is a friction ring fixedly fitted onto a one-way rotary disc 3. Specifically, the one-way rotary disc 3 is provided with a frustum 31, which is concentrically and coaxially arranged with the one-way rotary disc 3. The friction ring is fixedly fitted onto the outside of the frustum 31. The hand-operated brake component 5 is provided with a brake protrusion 52 that cooperates with the friction ring. The brake protrusion 52 is located on the outside of the friction ring. When the fingers squeeze together, causing the brake operating part 51 and the base operating part 111 to move closer to each other (since the base operating part 111 is relatively stationary, that is, the brake operating part 51 moves towards the base operating part 111), the brake protrusion 52 moves towards the friction ring under the action of the hand-operated brake component 5 and abuts against the outer wall of the friction ring. Under the action of mutual friction between the two, the braking effect is achieved. When the fingers are opened, the external force exerted by the user on the brake operating part 51 disappears, and the brake protrusion 52 will not exert a force on the friction ring, that is, the mutual friction between the two disappears, thereby releasing the brake.

[0042] In this embodiment, see Figure 2 and Figure 3 The base 1 includes an upper cover 11 and a sealing cover 12. The upper cover 11 and the sealing cover 12 are fixedly connected and cooperate to form a receiving cavity 13. The hand-operated brake component 5 is disposed in the receiving cavity 13. To save installation space, the hand-operated brake component 5 is horizontally rotatably disposed in the receiving cavity 13. Of course, in other embodiments, the hand-operated brake component 5 can also be disposed in the receiving cavity 13 in other ways, such as vertical installation, depending on actual needs.

[0043] The end of the hand-operated brake 5 that is away from the brake operating part 51 is rotatably connected to the receiving cavity 13. The brake protrusion 52 is provided in the middle of the hand-operated brake 5, which makes the operating lever arm of the hand-operated brake 5 longer and the operation more effortless. When the brake operating part 51 and the base operating part 111 move away from each other and move closer to each other, the hand-operated brake 5 swings with the brake operating part 51 relative to the base 1.

[0044] The upper cover 11 is provided with a notch 114 for the brake operation part 51 to extend from the accommodating cavity 13. The base operation part 111 is located on the side of the notch 114. Specifically, in this embodiment, the stepped groove 112 is located outside the notch 114, that is, after the brake operation part 51 extends out of the notch 114, it lies on the stepped groove 112.

[0045] In this embodiment, see Figure 2 An elastic element 7 is provided inside the accommodating cavity 13. The elastic element 7 ensures that the hand-squeezed brake 5 always has a tendency to release the brake on the one-way turntable 3. By providing the elastic element 7, when the user releases their finger during the braking control of the dehydration basket 4, the elastic element 7 drives the hand-squeezed brake 5 to move in the direction of releasing the brake under the action of elastic force, making the operation more convenient.

[0046] Preferably, in order to facilitate installation and improve the elasticity of the elastic element 7, the elastic element 7 is a metal elastic sheet, and a positioning post 131 is provided in the accommodating cavity 13. One end of the elastic element 7 is connected to the hand-operated brake element 5, and the other end of the elastic element 7 abuts against the positioning post 131.

[0047] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
