[0019] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0020] As Figure 1 shown, a device for incubating and interpreting a colloidal gold or carbon microarray chip card includes a homogenizing mask 2. A module camera 1 is provided on the homogenizing mask 2. In this embodiment, the module camera 1 is arranged on the top of the homogenizing mask 2, with the lens extending into the homogenizing mask 2, and the rest is fixed to the outside of the homogenizing mask 2 by screws, for identifying the QR code of the detection card below and taking photos for sampling. The bottom end of the homogenizing mask 2 is fixedly connected to a metal card slot 7. A corresponding slot is provided in the upper part of the metal card slot 7 for placing the colloidal gold / carbon microarray chip card. A heating film 8 is attached to the bottom of the metal card slot 7. The heating film 8 has double-sided adhesive on its back and is pasted on the bottom of the metal card slot 7 for heating the metal card slot 7.

[0021] A contact switch 6 is provided at the end side of the slot of the metal card slot 7 for touching and sensing whether the colloidal gold / carbon microarray chip card is inserted in place. A temperature control switch 9 is provided on the metal card slot 7 for sensing the temperature of the heating film 8. In this embodiment, the temperature control switch 9 is attached to the heating film 8 and fixed to the metal card slot 7 by screws, and there are holes at the corresponding position of the heating film 8 for the fixing screws to pass through. The temperature control switch 9 is electrically connected in series with the heating film 8 to the control circuit board 10 for controlling the on / off of the power supply of the heating film 8 according to the sensed temperature. The temperature control switch 9 directly controls the temperature of the metal card slot 7: when the preset temperature of the temperature control switch 9 is reached, the temperature control switch 9 automatically disconnects, so that the heating film 8 stops heating the metal card slot 7. When the temperature is lower than the preset temperature of the temperature control switch 9, the temperature control switch 9 is in a normally on state, and the heating film 8 will continuously heat the metal card slot 7. In this way, through the power calculation of the heating film 8 and the heat conduction calculation of the material of the metal card slot 7, the temperature range of 40°C ± 0.5°C can be achieved at the contact surface between the metal card slot 7 and the detection card. The contact switch 6 and the module camera 1 are respectively electrically connected to the control circuit board 10 for controlling the operation of the module camera 1 and the heating film 8 according to the signal of the contact switch 6.

[0022] As Figure 1 and Figure 3 shown, a ring-shaped LED light board 3 is provided at the bottom of the homogenizing mask 2. The ring-shaped LED light board 3 is electrically connected to the control circuit board 10 for providing light source for the homogenizing mask 2.

[0023] A homogenizing coating is provided on the inner wall of the homogenizing mask 2 to enhance the intensity of light source diffuse reflection and form a uniform and reliable ambient light.

[0024] As Figure 2 and Figure 3As shown, the bottom end of the light homogenizing mask 2 is connected to the metal card slot 7 through a support structure. In this embodiment, after the bottom end of the light homogenizing mask 2 is attached to the annular LED light board 3, it is fixed to the metal card slot 7 by screws and hexagon studs, so that a gap is formed between its bottom end and the metal card slot 7, and a card shell pressing plate 4 is provided in this gap. A card shell compression spring 5 is provided on the card shell pressing plate 4. In this embodiment, as Figure 1 shown, the card shell compression spring 5 is fixed to the bottom of the card shell pressing plate 4 by screws, and the card shell pressing plate 4 is fixed to the upper end of the metal card slot 7, so that the card shell compression spring 5 provides a certain elastic downward pre-tightening force to the colloidal gold / carbon microarray chip card inserted into the slot of the metal card slot 7, making the colloidal gold / carbon microarray chip card as a test card fit better with the metal card slot 7.

[0025] The bottom end of the metal card slot 7 is supported and connected to the base 11, and the control circuit board 10 is located between the metal card slot 7 and the base 11 and is fixed to the base 11.

[0026] The base 11 is sleeved with a housing 13 for covering and protecting the module camera 1, the light homogenizing mask 2, the metal card slot 7 and the control circuit board 10.

[0027] As Figure 4 and Figure 5 shown, an outer shell card insertion port 12 and an outer shell power port 14 are provided on the side wall of the outer shell 13. The outer shell card insertion port 12 is opposite to the slot opening of the metal card slot 7 for inserting the colloidal gold / carbon microarray chip card. The outer shell power port 14 is internally electrically connected to the control circuit board 10 and externally connected to a power source through a corresponding cable.

[0028] The heating film 8 is a polyamide heating film.

[0029] In this embodiment, a Bluetooth module can be set on the control circuit board 10 to facilitate communication with a host computer or a mobile terminal APP.

[0030] Working process and principle of the present invention After inserting the power supply and turning on the machine → the metal card slot 7 is heated to the fixed temperature of the temperature control switch 9 → the mobile phone APP successfully connects to the Bluetooth module of the device, and the module camera 1 recognizes the QR code of the test card to confirm the incubation time and the type of test product → insert the colloidal gold / carbon microarray chip card → the test card touches the contact switch 6 to start the incubation countdown → after the incubation countdown ends, the module camera 1 takes a photo and transmits the test card photo to the mobile phone APP through the Bluetooth module, and the mobile phone APP performs corresponding interpretation.

[0031] Those skilled in the art can understand that the relevant modules involved in the present invention and the functions they implement can be achieved by loading conventional computer software programs or related protocols in the prior art on the improved hardware and the devices, components or systems composed thereof, rather than improving the computer software programs or related protocols in the prior art. For example, the improved computer hardware system can still achieve specific functions of the hardware system by loading the existing software operating system. Therefore, it can be understood that the innovation of the present invention lies in the improvement of the hardware modules in the prior art and their connection and combination relationships, rather than merely the improvement of the software or protocol loaded in the hardware modules to achieve related functions.
