[0035] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0036] The following describes the heating device for the detection cartridge and the sample detection equipment of the present invention with reference to the accompanying drawings.

[0037] like Figures 1 to 3 As shown, the utility model provides a heating device for a detection cartridge, wherein the heating device for a detection cartridge comprises:

[0038] The limit seat mechanism 100 forms an installation space 140 for the detection cartridge 300 to be inserted into;

[0039] The laminating heating mechanism 200 includes an elastic support member 210, a heating module 220 and a positioning block 230 arranged in sequence from bottom to top in the installation space 140. The positioning block 230 is connected to the bottom wall of the installation space 140 and forms a limited opening 231. A heating laminating portion 224 is protruded from the heating module 220. The heating laminating portion 224 extends from the limiting opening 231 and is used to laminat e heat transfer with the bottom end of the detection card box 300. The elastic support member 210 is arranged on the bottom wall of the installation space 140 and can elastically support the heating module 220.

[0040] When the detection card box 300 uses the above-mentioned heating device, since it includes a limit seat mechanism 100 and a bonding heating mechanism 200, when the detection card box 300 is inserted into the installation space 140 formed by the limit seat mechanism 100, the elastic support member 210 located below the positioning block 230 in the bonding heating mechanism 200 can elastically support the heating module 220, so that the heating bonding portion 224 on the heating module 220 is bonded to the bottom end of the detection card box 300 for heat transfer, and since the elastic support member 210 has an elastic function, the bonding position can be adaptively adjusted through elastic deformation to ensure that the heating bonding portion 224 and the detection card box 300 are stably bonded, avoiding the phenomenon of batch differences in temperature rise rate, thereby improving the use effect of the equipment.

[0041] Specifically, the limit seat mechanism 100 includes a lower mounting plate 110, an upper mounting plate 120 and a clamping assembly 130. The lower mounting plate 110 forms an installation space 140, and a clamping assembly 130 is provided on the upper side of the lower mounting plate 110. The clamping assembly 130 is used to clamp or loosen the detection card box 300 in the installation space 140. The upper mounting plate 120 is provided on the upper side of the lower mounting plate 110 and is used to cover the clamping assembly 130.

[0042] Furthermore, the positioning block 230 can be detachably mounted on the bottom wall of the installation space 140 by means of fasteners, which may be bolts or screws, and a space must be formed between the positioning block 230 and the bottom wall of the installation space 140 for accommodating the elastic support member 210 and the heating module 220 for lifting and lowering.

[0043] See also Figures 2 to 5In this embodiment of the present invention, the laminating heating mechanism 200 further includes a heat shield 240 located below the heating module 220. The heat shield 240 is disposed on the bottom wall of the installation space 140 and defines a mounting hole 241. The elastic support member 210 is positioned within the mounting hole 241. The addition of the heat shield 240 not only provides thermal insulation on the bottom side of the heating module 220, preventing heat transfer downward, but also serves as a position limiter for the elastic support member 210. Specifically, to ensure that the elastic support member 210 supports the heating module 220, during compression assembly, the lower end of the elastic support member 210 abuts the bottom wall of the installation space 140, while the upper end extends beyond the mounting hole 241. Furthermore, the heat shield 240 defines at least two mounting holes 241, spaced apart in an annular pattern. The number of elastic support members 210 corresponds to the number of mounting holes 241, and the elastic support members 210 are positioned within the mounting holes 241 in a one-to-one correspondence.

[0044] like Figure 8 As shown, in this embodiment of the utility model, a first limiting groove 150 for accommodating the heat insulation board 240 is formed on the bottom wall of the installation space 140. The addition of the first limiting groove 150 facilitates the assembly and disassembly of the heat insulation board 240 within the installation space 140. Specifically, the first limiting groove 150 can stop and limit the heat insulation board 240 at the four corners of the heat insulation board 240, and the height of the heat insulation board 240 can be higher than the height of the first limiting groove 150, so that the upper end portion of the heat insulation board 240 can be placed together with the heating module 220 in the lower installation space 232 formed on the lower side of the positioning block 230, thereby achieving upper and lower end positioning.

[0045] See also Figures 3 to 5 In this embodiment of the present invention, a side of the heat shield 240 facing the heating module 220 further includes a clearance groove 242 for accommodating the electronic components on the heating module 220. Specifically, the electronic components on the heating module 220 are arranged to protrude toward the side facing the heat shield 240. The addition of the clearance groove 242 not only reserves space for the electronic components, preventing them from being directly press-fitted onto the heat shield 240, but also serves as a position limiter for the heating module 220. More specifically, the electronic components on the heating module 220 can be configured as a temperature protection switch.

[0046] See also Figures 3 to 6In the embodiment of the present invention, the heating module 220 includes a heating block 221 and an electric heating element 222. The heating block 221 includes a heating substrate 223 and a heating bonding portion 224. The electric heating element 222 is stacked on the lower side of the heating substrate 223 and located on the upper side of the heat insulation plate 240. The heating bonding portion 224 is protruding from the upper side of the heating substrate 223. That is, when the electric heating element 222 is energized, it can heat the heating block 221 and heat the detection cartridge 300 through heat transfer through the bonding between the heating bonding portion 224 and the detection cartridge 300. In addition, a lower mounting space 232 is formed on the lower side of the positioning block 230 for stacking the heating substrate 223 and the electric heating element 222. The addition of the lower mounting space 232 further serves to limit the heating module 220, thereby ensuring assembly reliability.

[0047] Furthermore, the stacked height of the heating substrate 223 and the electric heating element 222 is less than the height of the lower installation space 232, so that the heating module 220 can be raised and lowered within the lower installation space 232 following the elastic deformation of the elastic support member 210. In addition, the heating block 221 can be configured as an integrally formed metal part, and the electric heating element 222 can be configured as an electric heating film, specifically a polyimide film (PI) electric heating film. The electric heating film is integrated with the heating block 221 through a heat-sealing process to form a heating module 220, and a temperature protection switch is connected to the side of the electric heating film facing the thermal insulation board 240.

[0048] In this embodiment of the present invention, a positioning rib 225 is protruded from the side of the heating base 223 facing the positioning block 230, and a second limiting groove 233 is formed on the wall of the lower installation space 232 to accommodate the positioning rib 225. The addition of the positioning rib 225 and the second limiting groove 233 further limits the position and ensures assembly reliability.

[0049] In the embodiment of the present invention, the positioning rib 225 includes two straight sections 226 arranged relatively parallel to each other. The straight sections 226 extend from one end of the heating substrate 223 away from the heating bonding portion 224 toward the heating bonding portion 224. The second limiting groove 233 has two limiting surfaces arranged in a one-to-one correspondence with the two straight sections 226. That is, by providing the positioning rib 225 with two straight sections 226 arranged in parallel and the two straight sections 226 corresponding to the two limiting surfaces of the second limiting groove 233, the limiting area can be increased. In addition, one end of the straight section 226 is limited to be located at the end of the heating substrate 223 away from the heating bonding portion 224 and the extension direction is set to extend toward the heating bonding portion 224, so as to unify the processing references of the limiting opening 231, the lower loading space 232, and the second limiting groove 233 on the positioning block 230. Furthermore, the positioning rib 225 further includes a curved section 227 connecting the two straight sections 226 . The curved section 227 is provided at one end of the straight section 226 close to the heating and laminating portion 224 and is curved outwardly between the two straight sections 226 .

[0050] like Figure 3 、 Figure 4 and Figure 7 As shown, in the embodiment of the present invention, the limiting opening 231 is open on the peripheral side of the positioning block 230, and the lower loading space 232 extends from the peripheral edge of the limiting opening 231 to the lower side of the positioning block 230 and includes a substrate accommodating section 234 and a pin accommodating section 235 arranged in sequence. The heating substrate 223 is placed in the substrate accommodating section 234, and the substrate accommodating section 234 is formed with a stop at each of the four corners of the heating substrate 223, thereby further improving the reliability of limiting the heating substrate 223. At the same time, the wiring pins of the electric heating element 222 can be placed in the pin accommodating section 235. Accordingly, the wiring pins on the electric heating element 222 should be arranged to extend from the side away from the limiting opening 231. The pin accommodating section 235 and the substrate accommodating section 234 are directly connected, which can facilitate the processing and manufacturing of the positioning block 230. Furthermore, the positioning block 230 can be provided with connection holes for fasteners to pass through on opposite sides of the lower installation space 232, so as to facilitate the connection between the positioning block 230 and the bottom wall of the installation space 140, and the width dimension of the pin accommodating section 235 is smaller than the width dimension of the substrate accommodating section 234.

[0051] Please see again Figure 3In an embodiment of the present invention, the number of elastic support members 210 can be at least two, and at least two elastic support members 210 are arranged in a ring-shaped interval on the bottom wall of the installation space 140 and elastically support the heating module 220 respectively. By limiting the number of elastic support members 210 to at least two, it can be ensured that different elastic support members 210 apply supporting forces to the heating module 220 at different positions to ensure the stability of the support. Specifically, the number of elastic support members 210 can be four, and the four elastic support members 210 can be arranged in a one-to-one correspondence with the four corner positions of the heating module 220. The elastic support members 210 include but are not limited to being springs, and other parts with elastic functions are also possible.

[0052] In the embodiment of the present invention, there is a gap between the wall surface of the limiting opening 231 and the heating and fitting portion 224. The existence of the gap and the ability of the elastic support member 210 to swing to a certain extent allow not only the height of the heating module 220 to be adaptively adjusted during the adaptive adjustment process, but also the horizontal position of the heating module 220 to be adjusted, thereby further improving the fit between the heating and fitting portion 224 and the detection cartridge 300. It can be understood that the limiting opening 231 and the peripheral side profile of the heating and fitting portion 224 are contoured.

[0053] like Figure 6 and Figure 11 As shown, in this embodiment of the present invention, the upper end of the heating and laminating portion 224 is concave to form a laminating cavity 228. The inner wall of the laminating cavity 228 is used to laminarly mate with the bottom end of the detection cartridge 300 for heat transfer. The addition of the laminating cavity 228 not only achieves alignment and lamination, but also serves as a position limiter. Specifically, the bottom end of the detection cartridge 300 is formed with a detection laminating portion 310 that is contoured to the laminating cavity 228.

[0054] See also Figure 9 In this embodiment of the present invention, the lower mounting plate 110 of the position limiting mechanism 100 includes a main body 111 defining an installation space 140 and two overlapping portions 112 disposed at opposite ends of the main body 111. The bottom surfaces of the two overlapping portions 112 are both higher than the bottom surface of the main body 111. The addition of the overlapping portions 112 facilitates the subsequent assembly of the position limiting mechanism 100 on the sample testing device.

[0055] Specifically, see Figure 9 and Figure 10The bottom surfaces of the main body 111 and the overlapping portion 112 are further provided with a first wire groove 113 and a second wire groove 114 in a one-to-one correspondence. The first wire groove 113 can be used for the wires connected to the wiring pins in the installation space 140 to pass through and extend to the second wire groove 114. The second wire groove 114 is away from the end of the first wire groove 113 and passes through the periphery of the overlapping portion 112. It can be understood that the wiring pins of all the electronic control components in the installation space 140 need to be connected to the external power supply through wires. The starting end of the first wire groove 113 starts from the bottom of one of the wiring pins and passes through the bottom of other wiring pins in the installation space 140 in sequence until it extends to the terminal leading to the second wire groove 114. In addition to the heating module 220 having wiring pins in the space 140, the limit seat mechanism 100 is also provided with an in-place detection member for detecting the position of the detection card box 300. The in-place detection member also has wiring pins, and a wire passing opening 115 is formed on the main body 111. The wire passing opening 115 can allow the wires connected to the wiring pins to extend downward from the installation space 140. Of course, the positioning block 230 can also be provided with a wire passing opening 115 at a position corresponding to the wiring pin. The first row of wire troughs 113 passes through all the wire passing openings 115, so that the wires of all wiring pins are guided to the second row of wire troughs 114 through the same first row of wire troughs 113, and then guided to the outside by the second row of wire troughs 114. At the same time, the lower mounting plate 110 is further provided with a first cable cover plate 116 and a second cable cover plate 117. The first cable cover plate 116 and the second cable cover plate 117 cover the first cable groove 113 and the second cable groove 114 in a one-to-one correspondence, and can be specifically detachable. The addition of the first cable cover plate 116 and the second cable cover plate 117 can play a role in protecting the wires.

[0056] In addition, the present invention further provides a sample testing device, wherein the sample testing device includes a test cartridge 300 and the above-described heating device for the test cartridge, wherein the test cartridge 300 is pluggable and removable within the installation space 140. Because the sample testing device adopts all the technical solutions of the above-described embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-described embodiments, and will not be detailed here.
