Description

An anhydrous capsule micro-semiconductor physical cooling ice belt worn on the human head

Technical field

The invention relates to the field of semiconductor refrigeration and medical devices, in particular to a micro-physical cooling ice belt or ice cap which can be worn on the head of a human body by using semiconductor refrigeration.

Background technique

The micro-physical cooling ice belt that is worn on the head of the human body by means of semiconductor refrigeration is a physical cooling device that is directly worn on the head of the human body and has its own refrigeration and temperature control performance. It is used for physical cooling of human body fever and is usually used in children's groups. Different from the traditional ice belt, the traditional ice belt itself has no refrigeration and temperature control performance, and must be placed in the refrigerator for pre-cooling before use.

The prior art structure is composed of a fixing belt, a water bladder, a soft rubber, a cold guide plate, a cooling sheet, a sponge pad, a radiator, and a fan. In its construction, there is a water bladder, which is applied to the human head for cold cooling and physical cooling. It is a plastic film product that is preset with water. On one of its outer surfaces, it is in close contact with a cold guide plate, which is heat exchanged with the cold guide plate, and is cooled from the inside to the entire water bladder. The cold guide plate is a heat-conducting metal plate, which is located in the center of the soft rubber. It is exposed in the soft rubber, and two faces are exposed. One surface is used for installing the cooling sheet, which absorbs the cold surface heat of the cooling piece and the other surface is closely attached. The outer surface of the water bladder; on the left and right sides of the soft rubber, each is connected with a fixing strap for wearing. This configuration of the prior art and the use of a water bladder as a means of applying a cold pack have the following drawbacks: first, it is to exchange heat between the outer surface of the water bladder side and the cold guide plate, and then from the inside to the inside. The water in the entire water bladder cools down. In this respect, the thermal resistance of the heat conduction between the cold guide plate and the outer surface of the water bladder will be relatively large, and the cooling rate will be relatively slow; on the other hand, the water bladder must compete for a certain amount of water, so that the entire water bladder is cooled down. The water must be cooled down first, so the cooling capacity requirements will be larger. However, if the cooling rate is slow and the cooling capacity is large, the corresponding cooling power should be large. The performance parameters and size specifications of the electronic components that accompany it will also increase, which will make the whole ice belt product look more cumbersome. . However, for the ice-belt product, it is also used in the children's group. To make it comfortable to wear, it is important to make the volume as small as possible and the weight as light as possible. Obviously, such ice belts with water bladders are light and small and subject to certain restrictions. Secondly, the water bladder is made of plastic film. It is a wearing part. It is easy to be punctured by accident. If the whole ice belt cannot be used, the ice belt can not be used. To solve this problem, only one more, even several water bladders can be used. However, there are more and more restrictions, and it is impossible to solve this inconvenient problem from the root cause. In addition, the water in the water bladder will be slowly evaporated, and it is necessary to replenish the water from time to time. In order to solve this problem, it is necessary to provide an injection hole on the water bladder and a separate injection device. This will undoubtedly increase unnecessary costs.

Summary of the invention

The object of the present invention is to overcome the shortcoming of the prior art due to the use of a water bladder as a cold compressing device, and the cooling capacity is large, so that the ice belt is light and small, and the comfort is limited, and the water bladder is The inconvenience of using one of the consumables and the water in the water bladder will increase the unnecessary cost. To this end, the present invention provides a waterless capsule micro-semiconductor physical cooling ice belt worn on a human body head. Since the present invention does not have a water bladder, there are no above-mentioned three unfavorable factors in the prior art, so that the ice belt technology can be made to be as small as possible, more comfortable to wear, more convenient to use, and lower in cost.

The technical solution adopted by the invention is: a water-free micro-semiconductor physical cooling ice belt worn on the head of the human body, which is composed of a fixing belt, a soft rubber, a cold guide sheet, a cold guide plate, a cooling sheet, a sponge pad, and a heat dissipation. Components, fans, etc. The utility model is characterized in that: on the cold guide plate, a cold guide sheet is arranged, and the joints are integrally connected by screw connection or riveting, and the guide fins are metal sheets having better thermal conductivity and certain elasticity; The cold guide plate and the cold guide sheet assembly are injected into the center of the soft rubber through the plastic injection molding process. After being integrated into one body, only one surface is exposed outside the guide plate for the installation of the cooling sheet, and the cold surface heat of the cooling sheet is absorbed. The cold guide sheets are all wrapped in soft rubber; a fixed strap is attached to the left and right sides of the soft rubber for wearing. With this design scheme, on the one hand, the heat of the cold guide plate can be directly transmitted to the surrounding soft rubber through the cold conductive film which is better wrapped by the thermal conductive property inside the soft rubber, so that the soft rubber achieves the effect of rapid cooling, so that The cooling rate is fast, the soft rubber thickness of the wrapped cold guide sheet is usually relatively thin, and the shape of the cold guide sheet is designed to be slightly smaller than the soft rubber to ensure uniform temperature around the surface of the soft rubber. Obviously, this is faster than the prior art in which the cold guide plate is in close contact with the outer surface of the water bladder, and then the heat is cooled from the surface to the inside of the entire water bladder, and no water bladder exists. The cooling capacity requirement will be smaller, that is, the cooling power will be relatively smaller, so that the ice strip product can be made smaller and lighter, so that the wearing comfort is better. On the other hand, the structure in which the cooling fins having a certain elasticity are wrapped in the soft rubber is used as a cold physical cooling device. First, when worn, it can be bent and deformed from person to person and is not used. Object limitation; second, it uses soft rubber surface to contact the forehead skin, which does not make people feel uncomfortable; third, there is no wearing parts, it is convenient to use, and they are formed by injection molding at a lower cost. .

The cold guide plate is provided with a screw hole and a heat sink screw connection.

The through-cooling plate is provided with a plurality of through holes, so that the soft glue on both sides of the cold guide sheet is connected to each other through the holes to prevent delamination of the soft rubber on both sides of the curved deformation.

The soft rubber is provided with a blind hole for inserting a temperature sensor.

The connecting structure of the fixing tape and the soft rubber is made of a material having the same melting point and welded by a high frequency.

The fixing belt has a shape of a belt, that is, an ice belt; and the shape is a hat shape, that is, an ice cap. In the present invention, the control circuit is a conventional technique and will not be described.

The invention has the advantages of compact structure, small volume and light weight, better wearing comfort, and no wearing parts of the water bladder, which is more convenient to use and lower in cost.
