The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, the embodiment of the utility model discloses a photo-curing working part, which is a main functional component of a photo-curing machine, wherein the photo-curing working part is detachably arranged on a host of the photo-curing machine, a general battery is arranged in the host, and the host is used for providing electric energy for the photo-curing working part.

As shown in fig. 2 and 3, the photo-curing working portion includes a metal housing 101, a photo-curing lamp 108, and an insulating structure. The metal housing 101 is a main supporting portion of the photo-curing working portion, a first end thereof is a lamp body mounting end for mounting the photo-curing lamp 108, and a second end thereof is a host mounting end for mounting to a host. A transfer shaft 102 is usually arranged at the mounting end of the host, and the light curing working part is detachably connected with the host by being inserted into an end jack of the host through the transfer shaft 102.

The light curing lamp 108 is arranged at the mounting end of the lamp body, the metal shell 101 is provided with a mounting cavity for arranging the lead 104 of the light curing lamp 108, the metal shell 101 is in a hollow structure state, the lead 104 of the light curing lamp 108 extends from one end (the mounting end of the lamp body) of the metal shell 101 to the other end (the mounting end of the host machine) through the mounting cavity, the end part of the switching shaft 102 is usually provided with the switching circuit board 105, and the lead 104 of the light curing lamp 108 extends to the position of the switching circuit board 105 and is electrically connected to the switching circuit board 105. One end of the adapter shaft 102 is generally provided with a threaded portion, and the adapter circuit board 105 is disposed at the other end of the adapter shaft 102, and the adapter shaft 102 is screwed to the host mounting end of the metal casing 101 through the threaded portion. After the light curing working part is inserted into the host of the light curing machine through the adapter shaft 102, the light curing lamp 108 is electrically connected with the host through the lead 104 and the adapter circuit board 105, so that a battery in the host can supply power for the light curing lamp 108 and the like and elements thereof.

As shown in fig. 4, a heat insulating structure is provided between the substrate 112 of the light curing lamp 108 and the inner wall of the metal housing 101. Specifically, the heat insulation structure may be the heat insulation cavity 107, the heat insulation pad 111, and may also include the heat insulation cavity 107 and the heat insulation pad 111, and the description will be given below by taking the heat insulation cavity 107 and the heat insulation pad 111 as examples.

The heat insulating pad 111 is disposed on the substrate 112 of the light curing lamp 108, and the heat insulating pad 111 may be directly fixed on the substrate 112 of the light curing lamp 108 or may be indirectly disposed on the substrate 112 of the light curing lamp 108 through other members. A heat insulation cavity 107 is formed between the heat insulation pad 111 and the inner wall of the metal housing 101, that is, the inner wall of the metal housing 101 is provided with the heat insulation cavity 107 recessed in a direction away from the heat insulation pad 111 at a position where the heat insulation pad 111 is provided, so as to ensure that a larger distance is provided between the substrate 112 of the light curing lamp 108 and the corresponding inner wall of the metal housing 101, thereby reducing heat conduction efficiency.

In summary, in the photocuring working portion provided by the utility model, the heat insulation pad 111 is disposed on the substrate 112 of the photocuring lamp 108, and the heat insulation pad 111 is closer to the inner wall of the metal casing 101 than the substrate 112, so that the heat conduction speed of the substrate 112 to the metal casing 101 can be reduced under the action of the heat insulation pad 111. Meanwhile, a heat insulation cavity 107 is further arranged between the heat insulation pad 111 and the inner wall of the metal shell 101, and compared with the heat insulation pad 111 directly attached to the inner wall of the metal shell 101, the heat insulation cavity 107 has lower heat transfer efficiency. Under the double heat insulation effect of the heat insulation pad 111 and the heat insulation cavity 107, the speed of heat conduction from the light curing lamp 108 to the metal shell 101 near the light curing lamp 108 can be slowed down, the local temperature of the metal shell 101 in the oral cavity is prevented from being too high, and the patient is prevented from being scalded.

Although the above embodiment adds the heat insulation pad 111 and the heat insulation chamber 107, which can prevent the local temperature of the metal housing 101 from being too high to a certain extent and reduce the risk of scalding the patient, heat still gathers near the light curing lamp 108, and as the on time of the light curing lamp 108 increases, the temperature of the metal housing 101 also continuously rises, so that the medical staff is required to turn off the light curing machine after a period of use, which definitely affects the use efficiency of the light curing machine.

Based on this, in an embodiment of the present utility model, a heat conductive wrapper 106 for conducting heat away is added to the photo-curing working portion. The heat-conducting packing material 106 is disposed between the heat-insulating pad 111 and the substrate 112, that is, the heat-conducting packing material 106 is attached to the substrate 112, and the heat-insulating pad 111 is attached to the heat-conducting packing material 106. The heat conducting packing material 106 extends into the mounting cavity, and in order to ensure better heat dissipation efficiency, the area of the heat conducting packing material 106 is as large as possible. The heat of the substrate 112 is transferred to the entire heat conductive packing material 106 through the portion in contact with the heat conductive packing material 106, and is transferred into the mounting chamber by the heat conductive packing material 106. As part of the heat of the substrate 112 is absorbed and transferred by the heat-conductive wrapping material 106, the heat retained near the light-curing lamp 108 is reduced, and then the heat of the metal housing 101 near the light-curing lamp 108 is reduced, and even if the starting time is increased, the heat is not increased sharply, so that the patient is prevented from being scalded, and the service life of the light-curing lamp 108 is prolonged due to the reduction of the heat near the light-curing lamp 108.

The heat conducting packing material 106 can be made of graphene or metal (red copper, aluminum and the like) as a heat conducting material, the heat conducting material is not limited, and the heat conducting material can be made of a material with high heat conductivity coefficient, and particularly a material with good heat conducting effect in the horizontal direction is more suitable for being used as a material of the heat conducting packing material 106.

Further, the portion of the thermally conductive encapsulant 106 located in the mounting cavity is wrapped around the outside of the conductive wire 104. In this embodiment, the heat conducting package material 106 and the wires 104 are fixed together by wrapping, so that the extending direction and the position of the wires 104 can be restrained by the rigidity of the heat conducting package material 106, and the electrical disconnection caused by the movement of the wires 104 can be avoided. In general, there are a plurality of wires 104, and the heat conducting package material 106 may encapsulate a plurality of wires 104 at the same time, or each wire 104 may encapsulate one heat conducting package material 106, which is not limited in the form of the heat conducting package material 106 in the present utility model.

The heat conducting packing material 106 may not contact with the inner wall of the metal casing 101 in the installation cavity, so as to reduce the conduction efficiency of the heat conducting packing material 106 to the metal casing 101, and avoid the rapid temperature rise of the metal casing 101. The heat conducting packing material 106 is located in the installation cavity and can be connected with the metal shell 101 through a plurality of heat conducting fins, so that heat of the heat conducting packing material 106 is conducted to the metal shell 101, and the heat is diffused into the air through the metal shell 101, and the positions of the heat conducting fins are far away from the part located in the oral cavity as far as possible.

In order to prevent the metal case 101 from being excessively hot when the heat dissipation is satisfied, in the present embodiment, the heat storage material body 110 for absorbing the heat of the heat conductive packing material 106 is filled in the installation cavity. The heat storage material body 110 may be a phase change heat storage material, for example, a phase change heat storage material such as phase change paraffin or phase change microcapsule, or a mixture of a phase change paraffin or other phase change material and a heat conducting material. The heat conducting packaging material 106 transfers heat at the substrate 112 of the light curing lamp 108 to the mounting cavity along the extending direction of the heat conducting packaging material, and radiates/conducts to the metal shell 101 for heat dissipation in the process; the installation cavity is filled with a heat storage material body 110 formed by a heat storage material, so that under a high heating working condition, the heat which is not dissipated by the metal shell 101 is absorbed and stored through the heat storage material body 110, and after the light curing machine stops working, the heat storage material body 110 slowly releases the stored heat to the metal shell 101, and the stored heat is diffused into the surrounding environment through the metal shell 101.

To ensure that heat transfer pack 106 is less likely to dissipate heat that is more likely to be absorbed and stored by heat storage material body 110. In this embodiment, the heat-conducting packaging material 106 passes through the heat-storage material body 110, that is, the heat-storage material body 110 wraps part of the heat-conducting packaging material 106, so as to improve the heat conduction efficiency, so that the heat of the heat-conducting packaging material 106 is absorbed by the heat-storage material body 110.

Since the heat storage material body 110 is made of a phase change material, its volume changes with temperature change, and at the same time, the heat storage material body 110 also has a certain fluidity with temperature increase, and in order to prevent leakage of the heat storage material body 110 due to volume expansion in a high temperature environment, a heat conductive adhesive layer (not shown in the drawing) is added in this embodiment. The heat conducting glue layers are arranged in the mounting cavity and are positioned on two sides of the heat storage material body 110, so that a heat storage cavity is formed between the heat conducting glue layers on two sides of the heat storage material body 110, and the heat storage material body 110 is positioned in the heat storage cavity. Note that, the heat storage material body 110 may also be made of a heat storage gel, and thus, a heat conducting glue layer may not be provided, and leakage of the heat storage material body 110 may be avoided.

Since the volume of the heat storage material body 110 increases due to the temperature rise, it is necessary to ensure that the heat storage cavity has a sufficient volume in order to ensure that the heat storage cavity can accommodate the heat storage material body 110 after the temperature rise. In this embodiment, the heat storage material body 110 is isolated in the heat storage cavity by the heat conducting glue layer, so that the heat storage material body 110 can be prevented from leaking or entering the vicinity of the light curing lamp 108 to affect the normal operation of the light curing lamp 108. In addition, there is exposed conductor at the connection between the wire 104 and the substrate 112 of the light curing lamp 108, and the heat conductive adhesive layer can also improve the insulation effect at the connection between the wire 104 and prevent short circuit.

As shown in fig. 2, the lamp body mounting end has a light outlet, the light curing lamp 108 is disposed in the cavity of the lamp body mounting end, and the light emitting portion of the light curing lamp 108 faces the light outlet, and the lens 103 is fixed at the light outlet through the locking member 109. The lens 103 gathers the light emitted from the light curing lamp 108, and the use effect is better, and the locking member 109 is used for fixing the lens 103, the light curing lamp 108, and the like.
