Description

Technical Field

[0001] The utility model relates to the field of gene sequencing equipment, and particularly relates to a capillary insulation furnace structure. Background Art

[0002] Generally, there are two types of insulation furnaces applied in the field of gene sequencing on the market. One is a super-high type with two blowers arranged up and down respectively (as shown in Figure 1 ), and the other is a super-high type with two juxtaposed sewn blowers (as shown in Figure 2 );

[0003] These two super-high type insulation furnace structures have the following three major problems or defects:

[0004] Because the furnace cavity is super-high type, the temperature inside the insulation furnace inevitably has a step phenomenon. Therefore, the first type uses two fans to take over and reconcile, and the second type uses two fans to blow air downward for reconciliation;

[0005] Because the furnace cavity is super-high type, the locking buckle in the middle of the insulation furnace is difficult to lock and seal the upper and lower parts, and without sealing, it is easier to cause the temperature in the furnace cavity to be uneven;

[0006] The furnace door is made of PC, with insufficient stiffness and self-deformation, making it impossible to seal. Content of the Utility Model

[0007] The utility model provides a capillary insulation furnace structure, which can solve at least one problem pointed out in the background art.

[0008] A capillary insulation furnace structure includes a furnace body and a furnace door. The furnace body has a furnace cavity, and the furnace door is used to close the furnace cavity;

[0009] A blower area and a capillary area are arranged in the furnace cavity. A blower is installed in the blower area, and the capillary area is used to accommodate capillaries. A heating area is arranged at the central position of the capillary area.

[0010] A sealing ring matching the outer shape of the furnace cavity is arranged on the inner side of the furnace door.

[0011] The sealing ring is made of ethylene propylene diene monomer rubber.

[0012] The furnace door is made of PPS.

[0013] At least one inner wall corner of the capillary area adopts an arc transition, so that the area of the capillary area except the heating area forms an annular duct.

[0014] The number of the blowers is at least one.

[0015] The air outlet of the blower is communicated with the capillary area.

[0016] The air outlet of the blower faces one section of the quasi-circular annular air duct.

[0017] At least one temperature sensor is installed in the furnace cavity.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: through the design of the blower and the inner arc surface of the capillary zone, the hot air can circulate and rotate in one direction inside the furnace body in the present utility model, making the temperature inside the furnace more uniform. In addition, a furnace door with higher strength is used in combination with an EPDM sealing ring to completely isolate the inside from the outside, preventing air leakage, thereby further reducing the interference with the temperature uniformity inside the furnace.

Detailed Embodiments

[0025] The following combines the drawings to describe in detail a specific embodiment of the present utility model, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiment.

[0026] As Figures 3 to 4 shown, a capillary heat preservation furnace structure provided by an embodiment of the present utility model includes a furnace body 3 and a furnace door 4. A furnace cavity 5 is provided inside the furnace body 3, and the furnace door 4 is used to close the furnace cavity 5;

[0027] Since the existing furnace door 4 is made of PC material and has insufficient stiffness, it deforms itself and cannot be sealed. Therefore, the furnace door 4 of the present utility model is made of PPS material with higher stiffness. After locking the door, the door does not deform. In combination with an ethylene propylene diene monomer (EPDM) sealing ring 6 that matches the outer shape of the furnace cavity 5, the inside is completely isolated from the outside, preventing air leakage, thereby reducing the interference with the temperature uniformity inside the furnace;

[0028] Existing holding furnaces, such as Figure 1 and Figure 2 shown, have a relatively high internal space (ultra-high type) in the existing holding furnace structure 1 and the existing holding furnace structure 2, resulting in uneven internal temperature. Therefore, it is necessary to separately install blowers at the upper and lower parts for adjustment or use two blowers side by side for adjustment. The ultra-high type space also makes the furnace door longer, and it is not easy to be sealed;

[0029] Based on this, the holding furnace of the present utility model adopts a square or approximately square structure, which compresses the space compared with the existing holding furnace. Firstly, it is convenient to make the temperature more uniform. Secondly, it can make the furnace door 4 shorter and easier to achieve sealing;

[0030] The installation of the furnace door 4 and the furnace body 3 of the present utility model adopts the existing hinge method and is fixed with a buckle;

[0031] The furnace cavity 5 of the present utility model is divided into two areas, namely a blowing area 7 and a capillary area 8. A blower 10 is installed in the blowing area 7, and the capillary area 8 is used to accommodate a capillary 11. A heating area 9 is arranged at the central position of the capillary area 8;

[0032] As Figure 3 shown, at least one inner wall corner of the capillary area 8 is transitioned with an arc surface 12, so that the area of the capillary area 8 except the heating area 9 forms an approximately circular ring-shaped air duct. In this embodiment, two arc surfaces 12 are used for transition as an example. The air outlet of the blower 10 is communicated with the capillary area 8, and the air outlet of the blower 10 faces one section of the approximately circular ring-shaped air duct;

[0033] The air outlet of the blower 10 in this embodiment is located at Figure 3 the position on the left side in Figure 3 . Therefore, the two arc surfaces 12 are located at the inner wall corners on the right side. The blower 10 blows air from the upper left corner downwards. When the hot air molecules reach the bottom, they can only turn to the right (the air direction is as shown by the arrow in

[0034] ). In addition, there are two arc surfaces 12 on the upper and lower sides on the right, making the flow of hot air molecules smoother. There is no turbulence or eddy current formed by dead corners in the entire furnace cavity 5, thus ensuring uniform temperature in the furnace cavity 5. In addition, a temperature sensor 13 is also installed in the furnace body 3 to better control the furnace temperature;

[0035] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit and basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.

[0036] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
