## Abstract

The present invention provides a capsule endoscope, including: an enclosure, including a main body portion and end portions located at both ends of the main body portion; a hardware component, arranged in an accommodating space enclosed by the enclosure, the hardware component including a battery component, the battery component being arranged in a space corresponding to the main body portion; a first thermal insulation material layer, arranged between the enclosure and the battery component; and a sealing layer, arranged between the hardware component and the thermal insulation material layer. The capsule endoscope can effectively reduce the thermal convection between the battery component and the enclosure, better concentrate the heat inside the enclosure, so that the battery component may reach a higher thermal equilibrium temperature, extend the working time of the battery component, and improve the stability of the capsule endoscope.

## Claims

### Claim 1

A capsule endoscope, comprising:
an enclosure, comprising a main body portion and end portions located at both ends of the main body portion;
a hardware component disposed within an accommodating space enclosed by the enclosure, wherein the hardware component comprises a battery component, the battery component is disposed in a space corresponding to the main body portion;
a first thermal insulation material layer disposed between the enclosure and the battery component; and
a sealing layer disposed between the hardware component and the first thermal insulation material layer.

### Claim 2 (depends on 1)

The capsule endoscope of claim 1, wherein the hardware component further comprises a circuit control component, and the first thermal insulation material layer is disposed between the enclosure and the circuit control component.

### Claim 3 (depends on 1)

The capsule endoscope of claim 1, wherein the thickness of the sealing layer is between 0.01 mm-0.02 mm.

### Claim 4 (depends on 1)

The capsule endoscope of claim 1, wherein the accommodating space enclosed by the enclosure is a vacuum space.

### Claim 5 (depends on 1)
