Description

Technical Field

[0001] The present invention relates to the field of heating devices, and in particular to a heater. Background Art

[0002] Heaters such as electric blankets or heated mattresses have long been widely used. They are heated by electric heating wires or heat-conducting fluids. Electric heating wire heating requires the deployment of almost non-extensible electric heating wires on flexible sheets or mattresses. When in use, the electric heating wires will seriously damage the user experience of mattresses or sheets - the body presses down after lying down, causing the surface area of ​​the mattress to increase, and the electric heating wire cannot be extended. It either pulls the surrounding mattress or sheets, or pulls the electric heating wire, which is easy to cause damage to the electric heating wire, accompanied by the risk of leakage; and when the heater encounters an irregularly shaped object for heating, it is easy to cause uneven local force on the heater, thereby damaging the heater. Some physical therapy products require heating of the joints. When the joint outer wrapping is moved, it will stretch sharply. Although the electric heating wire can be wound to avoid the tension being concentrated on the electric heating wire, it is extremely difficult to achieve the same extensibility in any direction, and it is also very troublesome to fix the electric heating wire. The electric heating wire has a small area, uneven heating, and the user experience is not good enough. Summary of the invention

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0020] Reference Figure 1-2An embodiment of the heater of the present invention comprises a retractable heating body 1, a power supply 2, a power supply controller 3, a data processor 4 and a power detection module 5; the retractable heating body 1 is heated by a conductive sponge 11; the power supply 2 is connected to the retractable heating body 1; the power supply controller 3 is connected to the power supply 2, and is used to control the input voltage of the power supply 2 to the retractable heating body 1 according to the output power of the power supply 2; the power detection module 5 is respectively connected to the power supply 2 and the power supply controller 3, and is used to detect the output power of the power supply 2 and output the detection result; the data processor 4 is respectively connected to the power supply controller 3 and the power detection module 5, and is used to receive the detection result signal sent by the power detection module 5 and control the power supply controller 3.

[0021] During operation, the power supply 2 supplies power to the retractable heating body 1 to make the retractable heating body 1 generate heat. If the object wrapped by the retractable heating body 1 needs to be moved or different objects need to be heated, the retractable heating body 1 will be squeezed or stretched during use and will have different resistivities. Therefore, in order to control the heating temperature of the retractable heating body 1, the present invention detects the output power of the power supply 2 to the retractable heating body 1 in real time through the power detection module 5 and sends a power signal containing the power value of the power supply 2 to the data processor 4. The data processor 4 is used to receive the detection result signal sent by the power detection module 5 to determine whether the power value output by the power supply 2 exceeds the preset threshold range; if the power value output by the power supply 2 exceeds the preset threshold range, the data processor 4 sends a control signal to the power controller 3 according to the judgment result; the power controller 3 adjusts the input power of the power supply 2 to the retractable heating body 1 according to the control signal, thereby controlling the temperature of the retractable heating body 1; and the retractable heating body 1 of the heater has excellent ductility, and the heater can adapt to irregular-shaped objects through the deformation of the retractable heating body 1, and can also adapt to objects of different shapes through the deformation of the retractable heating body 1. One heater can heat or keep warm for a variety of objects, and has stronger applicability.

[0022] In some embodiments, the power detection module 5 includes a voltage sensing unit and a current sensing unit. The voltage sensing unit is used to detect the output voltage of the power supply 2 in real time, and the current sensing unit is used to detect the output current of the power supply 2 in real time. The power value output by the power supply 2 can be obtained by multiplying the detected voltage and current.

[0023] In some embodiments, the power controller 3 is a converter, through which the output voltage or output current of the power supply 2 can be controlled.

[0024] Reference Figure 3Furthermore, the heater also includes a temperature sensor, which is connected to the power controller 3. The temperature of the conductive sponge 11 can be detected by the temperature sensor, and the change in the temperature of the conductive sponge 11 can facilitate the user to understand the state of the heater, and the maximum output power value of the power supply 2 can be adjusted by the manual adjustment device to control the temperature of the heater.

[0025] Furthermore, the retractable heating body 1 includes a conductive sponge 11 and an outer layer 12, the conductive sponge 11 is connected to the power controller 3, and the outer layer 12 is arranged outside the conductive sponge 11. The conductive sponge 11 has good flexibility, elasticity and ductility, is easy to stretch during use, and is easy to restore to its original state after deformation, and is not easy to be damaged. The retractable heating body 1 has excellent ductility. The heater can adapt to irregular-shaped objects through the deformation of the retractable heating body 1, and can also adapt to objects of different shapes through the deformation of the retractable heating body 1. One heater can heat or keep warm a variety of objects, and has stronger applicability. It is not only easy to use, but also has a wide range of applications.

[0026] Furthermore, the retractable heating body 1 may be partially provided with the conductive sponge 11 inside or entirely provided with the conductive sponge 11 .

[0027] Furthermore, the outer covering layer 12 is one or more of insulating sponge, silicone, leather, and cloth. When the outer covering layer 12 is completely wrapped around the outside of the conductive sponge 11 and the heating interlayer does not need too much ductility, a material with poor elasticity such as leather or cloth can be used as the outer covering layer 12. When the heating interlayer needs to have good elasticity, silicone can be used as the outer covering layer 12. In other embodiments, the outer covering layer 12 can be partially made of silicone material with good elasticity and partially made of leather or cloth with poor elasticity, which is used in the case where the heating interlayer needs to have good elasticity in some positions.

[0028] Reference Figure 2 Furthermore, the retractable heating body 1 is provided with a positioning buckle 13, and the retractable heating body 1 is connected with the positioning buckle 13 to enclose a storage space. When in use, the positioning buckle 13 can be opened to expand the retractable heating body 1, so that objects can be placed in the storage space more easily, and then the positioning buckle 13 can be fastened to close the storage space, so that objects are not easy to fall. The positioning buckle 13 can be used to expand and close the retractable heating body 1, so that objects with irregular shapes can be placed in the storage space more easily, which is more convenient to use.

[0029] Furthermore, the positioning buckle 13 is a Velcro, which is convenient to open and close. By using Velcro as the positioning buckle 13, the telescopic heating body 1 can be more convenient to unfold and close.

[0030] In some embodiments, the retractable heating body 1 is provided with a through opening, and the opening is adapted to be provided with a zipper 14, which is used to open or close the opening. The zipper 14 can be opened or closed to conveniently open the storage space, and part of the objects in the storage space can be taken out more conveniently, which is more convenient when the objects in the storage space do not need to be completely taken out.

[0031] Furthermore, the heater also includes a heating frame, and the retractable heating body 1 is detachably arranged on the outside of the heating frame. In the case where some objects are easily damaged and it is inconvenient to directly contact the retractable heating body 1, the heating frame can be used as an aid. When in use, the object is placed in the heating frame, and the retractable heating body 1 is arranged on the outside of the heating frame to heat or keep the object warm to prevent the object from being squeezed. After use, the retractable heating body 1 can be removed from the heating frame, which is convenient to use.

[0032] Furthermore, the heating rack is provided with a hook, and the retractable heating body is provided with a hanging ring for connecting the hook. The retractable heating body can be more conveniently connected to the heating rack through the connection between the hook and the hanging ring.

[0033] In some embodiments, the heating rack is retractable, and the shape and size of the space enclosed inside the heating rack can be adjusted by stretching and compressing.

[0034] Furthermore, the retractable heating body 1 matches heating racks of various specifications. Since the structure of the heating rack is relatively fixed, heating racks of different specifications correspond to objects of different specifications, and the retractable heating body 1 has retractability and ductility, and can match multiple heating racks at the same time, or multiple retractable heating bodies 1 can be connected to each other to cooperate with one or more heating racks, which is more flexible to use.

[0035] Furthermore, a storage bag 15 is provided on the retractable heating body 1, and part of the storage bag 15 is fixedly connected to the retractable heating body 1. The storage bag 15 is used to be folded up when the retractable heating body 1 is not in use, so that the heater is more convenient to carry.

[0036] Furthermore, the conductive sponge 11 includes a heating trunk and a key heating area, and the key heating area includes one or more heating sponge columns with a cross section smaller than the heating trunk. A cross section smaller than the heating trunk will result in a greater resistance in the area, and the entire conductive sponge 11 cannot achieve the goal of reasonable current introduction and reasonable power distribution. Therefore, although the interlayer is almost a whole piece of conductive sponge 11 of a certain thickness, the sponge is appropriately divided, which makes it easier to introduce current, and on the other hand, makes finer cuts in places where higher heat is required to obtain greater resistance, thereby obtaining a greater power density per unit area in the required area, thereby achieving a local higher heat effect.

[0037] The heating part of the heater of the present invention has excellent ductility. The heater can adapt to irregular-shaped objects through the deformation of the retractable heating body 1, and can also adapt to objects of different shapes through the deformation of the retractable heating body 1. One heater can heat or keep warm a variety of objects, with stronger applicability. It is used for heating bedding and clothing and has an excellent tactile experience.
