Description

Technical Field

[0001] The utility model relates to the technical field of rotating dining tables, in particular to a desktop electric turntable. Background Art

[0002] In the catering industry, electric turntables for dining tables are widely used, allowing diners to easily rotate the electric turntables for convenient access to food and drinks. However, most of the electric turntables for dining tables on the market are modified from existing dining tables. A motor is installed in the dining table, and the output shaft of the motor extends upward out of the table top and is connected to the turntable. The motor drives the turntable to rotate normal to the table top of the dining table, making the electric turntable and the dining table an integrated structure. If the merchant needs to replace the electric turntable, it will cost a lot.

[0003] And because the turntable is directly connected to the motor, when the table turntable starts to rotate, it cannot be manually stopped, accelerated or reversed, otherwise the motor or transmission mechanism is easily damaged, making it inconvenient for guests to pick up dishes when dining.

[0004] Later, a desktop electric turntable separated from the dining table appeared, which includes a bottom cover, an upper cover, a motor mounted on the bottom cover, and a control board for controlling the motor. The power supply of the desktop electric turntable can be set on the bottom cover, or can be set outside the desktop electric turntable by a cable connection.

[0005] Chinese patent ZL202321172465.6 discloses an infrared automatic rotating dinner plate. It includes a chassis, a movable plate, a drive motor and a drive circuit, the movable plate is arranged above the chassis, a receiving cavity is arranged between the movable plate and the chassis, the drive motor and the drive circuit are both arranged in the receiving cavity, the drive circuit is electrically connected to the drive motor, the drive motor is connected to the movable plate to drive the movable plate to rotate; the drive circuit includes an infrared transceiver module, a main control module, a power module and a motor drive module, the power module is respectively connected to the infrared transceiver module, the main control module and the motor drive module, the infrared transceiver module is connected to the main control module, the main control module is connected to the motor drive module, and the motor drive module is connected to the drive motor; an infrared reflective strip is fixedly installed on the inner side of the movable plate, the infrared reflective strip receives the infrared light signal output by the infrared transceiver module, and reflects the infrared light signal to the infrared transceiver module. This solution requires a huge annular infrared reflective strip to be fixed on the movable plate. The infrared reflective strip is large in size and requires a large cutting mold for cutting, or a CNC cutting machine for production, which has high processing costs. When a large-sized infrared sensitive strip is manually installed, it is easy to deform and the installation efficiency is low. If it is positioned and installed by a tooling mold, the installation efficiency can be improved, but the production cost of a large tooling mold is also very high. Therefore, this solution leads to high production costs. Utility Model Content

[0006] The utility model aims to provide a desktop electric turntable with a simple structure and capable of reducing costs.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

That is, the annular array is composed of segmented materials and can be formed by segmented fixing or coating without the need for a large mold. For example, a circular array can be made by pasting a black EVA sheet on the inner wall. For another example, the upper cover is placed on a turntable, and each time it rotates a predetermined angle, an ink block of a predetermined color and shape is printed on the inner wall. Greatly reducing production costs.

[0016] Since the load-bearing ring and the upper cover are independent of each other, that is, there is no rigid transmission connection between the two, the user can manually pause, accelerate or reverse the upper cover during the rotation of the upper cover without damaging the motor, making it very convenient for guests to pick up the dishes they want to enjoy when dining.

[0017] Furthermore, a gear ring is arranged on the outer circumference of the load-bearing ring, and the motor drives the load-bearing ring to rotate through the reducer and the gear ring. After deceleration, a smaller motor can be used to drive the upper cover, which is beneficial to reducing the power demand of the motor and reducing costs.
