Description

Technical Field

[0001] The utility model belongs to the field of heating equipment, and in particular relates to a warming table mat with a replaceable surface layer. Background Art

[0002] Whether it is office work or study, it needs to be done on the desk. In winter, due to the low temperature, for people who need to work at a desk, when writing or operating a computer, their hands are exposed to the outside for a long time, and they are easily frozen in the low temperature state, affecting their activities. Gloves cannot generate heat and have limited warming effect. Turning on the air conditioner consumes too many resources. Therefore, modern people often place warm table mats on the desk to provide hand warmth for people who work at desks in winter.

[0003] At present, the existing warming table mats are made of multiple layers of fabric, and it is difficult to remove the fabric. However, during long-term use, the fabric is easily stained. Since the warming table mat needs to be powered on, cleaning can easily cause water to enter the interior, causing the warming table mat to malfunction.

[0004] Therefore, in view of the problems that the existing warming table mats are difficult to disassemble, the dirty fabrics cannot be cleaned, and cleaning easily causes the warming table mats to malfunction, the existing warming table mats are improved and a warming table mat with a replaceable surface layer is designed, which makes it convenient to disassemble and replace the top layer of fabric and clean the replaced fabric. Utility Model Content

[0005] In order to overcome the problem that the existing warm table mat is made of multiple layers of fabric, it is difficult to disassemble the fabric and it is impossible to clean the dirty fabric.

[0006] The technical solution of the utility model is: a warming table mat with a replaceable surface layer, comprising a supporting frame, a heating layer, a fabric layer, Velcro, a heat-insulating layer, and a thermally conductive copper plate; a heating layer is arranged in the supporting frame, a fabric layer is arranged on the top of the supporting frame, a Velcro is connected between the fabric layer and the supporting frame, a heat-insulating layer is arranged in the supporting frame below the heating layer, and a thermally conductive copper plate is arranged in the supporting frame above the heating layer.

[0007] Preferably, by changing the original stitching connection to an easy-to-detach Velcro connection, the fabric layer can be easily separated from the heating layer, making it convenient to clean the fabric layer with dirty surface. The heating layer is responsible for generating heat, and the heat-insulating layer and the heat-conducting copper plate conduct the heat of the heating layer to the fabric layer, providing concentrated heat for the user's hands.

[0008] Preferably, an anti-skew plate is fixedly connected to the front side of the support frame at a 90-degree angle to the support frame, the bottom end of the support frame is close to the table top, and the anti-skew plate is close to the edge of the table. The anti-skew plate and the support frame are both made of hard materials and have supporting capabilities. By having the anti-skew plate close to the edge of the table, the angle deviation of the warm table mat can be limited to prevent it from skewing.

[0009] Preferably, two heating layers with built-in heating wires are arranged opposite to each other on the left and right sides of the supporting frame. USB sockets electrically connected to the heating wires are connected on both sides of the left and right sides of the supporting frame. The heating wires of the heating layer are powered by plugging a USB cable into the USB interface to provide a warming effect. The design of the two heating layers enables the thermal insulation pad to perform local heating and zone control.

[0010] Preferably, an insulation layer made of cut polyurethane foam board is placed in the support frame and close to the inner wall of the support frame, and the bottom end of the heating layer is close to the top end of the insulation layer. The polyurethane foam board has good thermal insulation effect, which can prevent the heat of the heating layer from being conducted downward, so that the heat generated by the heating layer can be concentrated and conducted upward, thereby improving the heating efficiency of the heating table mat.

[0011] Preferably, a waterproof layer is provided in the support frame, which is close to the inner wall of the support frame. The waterproof layer is provided at the top of the heating layer. A thermal conductive copper plate with a T-shaped cross-section is provided above the waterproof layer. The waterproof layer can protect the heating layer and prevent water vapor from entering the heating layer and causing damage to the heating wire. The thermal conductive copper plate has good thermal conductivity and can direct the heat generated by the heating layer upward.

[0012] Preferably, a support groove is opened on the support frame, and the thermally conductive copper plate is placed in the support groove, and the bottom end of the fabric is close to the top of the thermally conductive copper plate. The support groove can provide support for the thermally conductive copper plate, so that the thermally conductive copper plate is close to the waterproof layer while avoiding applying force on the thermally conductive copper plate to cause the thermally conductive copper plate to squeeze the waterproof layer and heating layer below and cause damage to the heating wire.

[0013] Preferably, a groove is provided on the support frame, in which the fleece surface of the Velcro is glued, and the hook surface of the Velcro is glued to the bottom of the fabric layer. The design of the groove allows the Velcro with a certain thickness to be stored in the groove, ensuring that the fabric layer on the surface of the supporting frame remains flat. Combined with the smooth thermal conductive copper plate that provides support, the adverse effects caused by the uneven support surface for office writing can be avoided.

[0014] Beneficial effects of the utility model:

[0015] 1. By changing the multi-layer sewing design of the original warming table mat, the fabric layers are stacked in the support frame, and the fabric and the support frame are connected by Velcro, so that the fabric can be removed and replaced after it is soiled, and the replaced fabric can be washed without washing the entire warming table mat, thus avoiding malfunction caused by the heating layer of the warming table mat coming into contact with water;

[0016] 2. The heat insulation layer separates the heating layer from the bottom of the frame and the table top. At the same time, the heat-conducting copper plate guides the temperature to the fabric, which plays a role in precise heat conduction and avoids waste caused by double-sided diffusion of heat.

[0017] 3. The design of two heating layers enables this heating table mat to achieve local heating and zone control, which improves the versatility of the heating table mat;

[0018] 4. The anti-skew plate is close to the edge of the table, which can adjust the position of the warm table mat to prevent it from shifting. At the same time, the fabric is close to the smooth surface of the heat dissipation copper plate, which provides support for the panel to avoid affecting the office or writing effect due to potholes.

After power is turned on, the heating wire starts to heat up. The heat insulation layer 5 cut by the polyurethane foam board has a good heat insulation effect, which can prevent the heat generated by the heating layer 2 from flowing downward. The heat of the heating layer 2 is transferred upward along the waterproof layer 9 to the heat-conducting copper plate 6, and the heat is transferred to the fabric layer 3 through the heat-conducting copper plate 6, providing heat for the hands of the user who works at the desk, and preventing the user's hands from being frozen by the low temperature in winter;
