[0002] The desk mat is mainly made of plastic, which has good anti-scalding, anti-skid and heat insulation effects, is easy to clean, and is suitable for coffee tables, the middle of tables and under crystal plates, and plays a decorative role in the home environment. With the development of modern education, more and more students need to review textbooks and write homework after school. Although the smooth surface of the desk is convenient for use, it is not conducive to students' use in cold weather because of cold fingers. The existing portable desk mat can provide lighting compensation and use electromagnetic coils for direct heating. However, due to the uncontrollable temperature, it is easy to make the temperature too high, affecting the use.

[0003] After searching, for example, the authorization announcement number (CN108903543A) is a smart multifunctional portable desk mat, including: a first area, the first area includes a power module, a sensor module and a control module, the power module is used to supply power to other modules, and the sensor module is used to sense the user's sitting posture or the light of the use environment; a second area, the second area includes a wireless charging module and an alarm module, the wireless charging module is used to provide a wireless charging function, and the alarm module is used to sound an alarm; a third area, the third area is provided with a first heating module, the first heating module is used to heat the third area; a fourth area, the fourth area includes a second heating module, and the second heating module is used to heat the fourth area. This device solves the problem that the existing desk mat cannot provide corresponding lighting compensation for students when using the desk. However, the device uses electromagnetic coils for direct heating, which will cause the temperature of the desk mat to be uncontrollable during use, resulting in the problem of excessive temperature, which is inconvenient to use and reduces the practicality of the device.

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs. Example

[0026] like Figures 1 to 4 As shown,

[0027] This embodiment includes:

[0028] A desk mat body 1 is used for laying on the surface of a desk. A control center made of a single-chip microcomputer is arranged inside the desk mat body 1, and a temperature sensor is arranged inside the desk mat body 1. The temperature of the desk mat body 1 is controlled by parameters set by the through-hole single-chip microcomputer. A plug hole 3 for easy connection is arranged on one side of the desk mat body 1. The plug hole 3 is powered on as a whole through a power cord 4 connected to the plug hole 3, so that the desk mat body 1 can be heated and used easily.

[0029] The surface of the table mat body 1 is made of high temperature resistant natural rubber material. Natural rubber is not only soft in texture, but also has no odor. In order to prevent the thread ends of the table mat body 1 from coming out when in use, a lock-edge weaving technique is used around the table mat body 1 to make the overall structure of the table mat body 1 more compact and reasonable, thereby increasing the service life of the table mat body 1. The bottom of the table mat body 1 is provided with an inclined anti-skid pattern for anti-skid fixation when placed. The anti-skid pattern is arranged at an inclination angle of 30 degrees to 45 degrees as a whole, and two interlaced oblique grooves, one deep and one shallow, are arranged inside the anti-skid pattern to further improve the anti-skid ability of the table mat body 1.

[0030] The water tank 5 is completely sealed and leak-proof. The sealed water tank 5 can effectively avoid leakage and conduction during heating, thereby improving the safety of the device. The water tank 5 is embedded in the interior of the table mat body 1. A circulating liquid with a low specific heat capacity is added to the interior of the water tank 5. The low specific heat capacity means that the circulating liquid can absorb less heat. In conjunction with the temperature sensor and the control of the single-chip microcomputer arranged inside the table mat body 1, the corresponding body adaptability can be effectively maintained, which is convenient for use.

[0031] A submersible water pump is also connected to the inside of the water tank 5. Because the inside of the water tank 5 needs to be heated for use in cold weather, the water pump also needs to be treated to resist high temperatures. Because of the low specific heat capacity of the circulating fluid, the increased temperature of the circulating fluid will not damage the internal structure of the water pump. The output end of the water pump is connected to one end of a circular tube 7 that passes through the side wall of the water tank 5, and the other end of the circular tube 7 is connected to the outer wall of the water tank 5. The circular tubes 7 are evenly arranged inside the table mat body 1, and the circulating fluid flows inside the circular tubes 7 to heat the table mat body 1.

[0032] In order to facilitate the carrying of the table mat body 1, except for the water tank 5 and the electric heating seat 6 which cannot be folded, other structures located inside the table mat body 1 are made of high temperature resistant and corrosion resistant flexible materials, and the same is true for the circular tube 7. This allows the table mat body 1 to be folded to reduce the occupied space when carried, making it easy to carry and move.

[0033] The filling port 2 is arranged at the top of the water tank 5, and the end of the filling port 2 passes through the top of the table mat body 1 and extends to the outside, and a sealing cover is provided on the top of the filling port 2. The total amount of circulating liquid inside the water tank 5 is adjusted through the filling port 2 to prevent the circulating liquid from being reduced and causing damage when the water tank 5 is heated, which is convenient for use.

[0034] A cover plate 11 is movably connected to the top of the electric heating seat 6, a magnetic crystal plate 13 is arranged in the middle of the cover plate 11, the magnetic crystal plate 13 is abutted against the bottom of the water tank 5, and a ring plate 12 is welded to the bottom of the cover plate 11, the ring plate 12 is movably connected to the card slot 8 arranged on the top of the electric heating seat 6, because a storage slot is arranged on the top of the electric heating seat 6, a cross-shaped bracket 9 is welded inside the storage slot, and the bracket 9 is provided with a limiting groove 10 for easy connection, and the limiting groove 10 is clamped with the electromagnetic coil, and the circulating fluid inside the water tank 5 is heated by the eddy current generated by the electromagnetic coil, thereby completing the heating of the entire table mat body 1.

[0035] How it works

[0036] When using the portable intelligent warm table mat, the power supply connection of the table mat body 1 is completed by connecting the power cord 4 to the socket 3, and then the regulation of the circulating liquid inside the water tank 5 is completed through the filling port 2. At this time, the control switch completes the work of the electric heating seat 6, and after the circulating liquid is heated up, the water pump is finally started. Under the action of the circular tube 7, the heating of the table mat body 1 is completed.
