[0002] The part for storing reagents in the immune analyzer is a reagent pot, and since a low-temperature environment is required for the storage of reagents, the reagent pot usually needs to be refrigerated and kept warm. The reagent pot cover is usually provided with a sampling hole and a warehouse door for taking and placing reagent bottles. Since the sampling hole is in an open state, and the warehouse door is frequently opened for taking and placing reagent bottles, the external normal-temperature air of the reagent pot contacts the sampling hole wall and the warehouse door edge wall at low temperature to produce condensation, and a large amount of condensed water will accumulate for a long time, increasing the risk of reagent contamination caused by the dropping of condensed water into the reagent pot, and the risk of equipment damage.

[0003] The existing reagent pot cover is generally provided with three layers, i.e. an upper cover, a heat preservation layer and a lower cover, and a circle of heating wires is arranged on the upper surface of the lower cover. This scheme cannot effectively prevent condensation around the sampling hole and the warehouse door. Due to the difference in functions, the amount of condensation water generated by the reagent pot cover, the sampling hole and the warehouse door is different. If this scheme is directly used for the sampling hole and the warehouse door, the anti-condensation effect around the sampling hole and the warehouse door cannot be consistent, and there is an uneven situation that there is no condensation water at one place and a large amount of condensation water at another place.

[0037] Pot cover embodiment:

[0038] Referring toFigures 1 to 4 The pot cover provided by the embodiment comprises a cover body 1, a heating wire 2, a first heat preservation layer 3 and a door 4.

[0039] The door 11, the two grooves 12 and the sample holes 13 are arranged on the cover body 1. The grooves 12 are recessed in the top wall of the cover body 1. The sample holes 13 are used for inserting a sampling needle into the reagent pot to suck reagents. The sample holes 13 are divided into two groups and arranged in the two grooves 12 respectively. All the sample holes 13 in each group penetrate the groove bottom of the groove 12. The sample holes 13 can be circular, waist-shaped, rectangular or polygonal. The door 11 is approximately trapezoidal in structure. The door 4 is connected to the door 11 in a hinged manner or detachably. The first heat preservation layer 3 is arranged on the bottom wall of the cover body 1. The heating wire 2 is arranged between the cover body 1 and the first heat preservation layer 3. The first heat preservation layer 3 is made of a material with low thermal conductivity, such as polystyrene or rubber sponge. The first heat preservation layer 3 not only can preserve heat for the pot body 6, but also can block the heat conduction of the heating wire 2 to the pot body 6.

[0040] The heating wire 2 comprises the second arrangement section 22, the third arrangement section 23 and the two first arrangement sections 21. The first arrangement section 21, the second arrangement section 22 and the third arrangement section 23 are connected into the same heating wire 2. The two first arrangement sections 21 are arranged around the sample holes 13 respectively. The second arrangement section 22 is arranged around the door 11.

[0041] Because the cold air in the reagent pot contacts with the external environment through the sample holes 13, the condensation is most likely to occur around the sample holes 13. When the reagent bottles are taken out or put in, the door 4 needs to be opened, which causes the external hot air to contact with the low-temperature gas in the door 11 and produce condensate water around the door 11. The frequency of opening the door 4 is related to the load of the experiment test. The heat exchange amount of the door 11 with the external environment is less than that of the sample holes 13 with the external environment. Therefore, the density of the heating wire 2 around the sample holes 13 is greater than that around the door 11. The density is the heat amount of the heating wire arranged in the unit area of the bottom wall, which is related to the material, length and diameter of the heating wire.

[0042] The bottom wall of the cover body 1 is provided with a second installation groove 15, a third installation groove 16 and two first installation grooves 14a / 14b. The second installation groove 15 extends along the periphery of the door opening 11, the third installation groove 16 extends along the periphery of the cover body 1, and the two first installation grooves 14a / 14b are respectively arranged corresponding to the corresponding grooves 12, and the first installation grooves 14a / 14b are arranged around the sampling hole 13. The second installation groove 15 is communicated with the first first installation groove 14a through two first communication grooves 18a / 18b, and the two first communication grooves 18a / 18b are arranged in parallel. The two first installation grooves 14a / 14b are communicated through two second communication grooves 19a / 19b, and the two second communication grooves 19a / 19b are arranged in parallel.

[0043] The second arrangement section 22 is arranged in the second installation groove 15, the third arrangement section 23 is arranged in the third installation groove 16, and the two first arrangement sections 21 are respectively arranged in the two first installation grooves 14a / 14b. Specifically:

[0044] The two ends of the third installation groove 16 are respectively provided with an outlet 162 and an inlet 161, and the outlet 162 and the inlet 161 are arranged adjacent to each other. The middle part of the third installation groove 16 is provided with a first communication part 163 and a second communication part 164, and the first communication part 163 is communicated with the first end of the second installation groove 15. The middle part of the second installation groove 15 is provided with a third communication part 151 and a fourth communication part 152, the third communication part 151 is communicated with the first first communication groove 18a, and in turn communicated with the first end of the first first installation groove 14a. The middle part of the first first installation groove 14a is provided with a fifth communication part 141 and a sixth communication part 142, the fifth communication part 141 is communicated with the first second communication groove 19a, and in turn communicated with the first end of the second first installation groove 14b. The second end of the second first installation groove 14b is communicated with the second second communication groove 19b, and the second second communication groove 19b is communicated with the sixth communication part 142. The second end of the first first installation groove 14a is communicated with the second first communication groove 18b, and the second first communication groove 18b is communicated with the second installation groove 15 through the fourth communication part 152. The second end of the second installation groove 15 is communicated with the third installation groove 16 through the second communication part 164.

[0045] The heating wire 2 enters from the inlet 161 of the third installation groove 16 and extends along the extension direction of the third installation groove 16 to the first communication part 163; then, the heating wire 2 enters from the first end of the second installation groove 15 and extends to the third communication part 151; then, the heating wire 2 enters from the first end of the first first installation groove 14a through the first first communication groove 18a and extends to the fifth communication part 141; then, the heating wire 2 enters from the first end of the second first installation groove 14b and extends along the extension direction of the second first installation groove 14b; then, the heating wire 2 exits from the second end of the second first installation groove 14b and extends to the sixth communication part 142 through the second second communication groove 19b; then, the heating wire 2 extends to the second end of the first first installation groove 14a and extends to the fourth communication part 152 through the second first communication groove 18b; then, the heating wire 2 extends along the extension direction of the second installation groove 15 to the second end of the second installation groove 15; then, the heating wire 2 extends to the second communication part 164 and enters the third installation groove 16; then, the heating wire 2 extends along the extension direction of the third installation groove 16 to the outlet 162.

[0046] In the embodiment, the openings of the first installation groove 14a / 14b, the second installation groove 15, the third installation groove 16, the first communication groove 18a / 18b and the second communication groove 19a / 19b are arranged downward. The width of the opening of the three installation grooves and the two communication grooves is slightly smaller than the corresponding groove depth, and the width of the opening is slightly smaller than the diameter of the heating wire 2, so that the heating wire 2 cannot easily come off the installation groove and the communication groove after being placed in the installation groove or the communication groove, thereby fixing the heating wire 2. The groove depth of the three installation grooves and the two communication grooves is slightly larger than the diameter of the heating wire 2, which ensures that the heating wire 2 is completely buried in the corresponding installation groove and communication groove.

[0047] In other embodiments, the width of the opening of the first installation groove, the second installation groove, the third installation groove, the first communication groove and the second communication groove is equal to the corresponding groove depth, and is greater than the diameter of the heating wire. After the heating wire is placed in the three installation grooves and the two communication grooves, it can be fixed by a fixing plate or a first heat preservation layer.

[0048] The cover body 1 is provided with an edge part 17 extending along the circumference of the cover body 1. The third installation groove 16 is arranged on the bottom wall of the edge part 17 and extends along the extension direction of the edge part 17, and the third arrangement section 23 is arranged in the third installation groove 16.

[0049] Due to the limited sealing degree of the pot cover and the pot body 6, a small amount of cold air will leak, and generally the pot cover will be opened only during maintenance, and the opening frequency is low. Therefore, the density of the heating wire 2 around the door hole 11 is greater than the density of the heating wire 2 at the edge part 17. The density is the heating amount of the heating wire arranged in the unit area of the bottom wall, and the heating amount is related to the material, length and diameter of the heating wire.

[0050] The heating wire 2 extends along a preset path, which includes a straight line, a curve, a circular arc or a combination thereof. The preset path includes the respective extension paths of the first mounting groove 14a / 14b, the second mounting groove 15, the third mounting groove 16, the first communication groove 18a / 18b and the second communication groove 19a / 19b, that is, the first mounting groove 14a / 14b, the second mounting groove 15, the third mounting groove 16, the first communication groove 18a / 18b and the second communication groove 19a / 19b all include a straight line, a curve, a circular arc or a combination thereof.

[0051] The heating wire 2 includes a heating material and a wrapping layer, and the wrapping layer is arranged on the outer periphery of the heating material. The heating material can be a nickel alloy filament or a constantan wire, and the wrapping layer is preferably silicone.

[0052] Referring to Figure 5 and Figure 6 , the pot cover further comprises a temperature control assembly 5. The temperature control assembly 5 can be arranged on the cover body 1, or can be arranged at a position other than the cover body 1. In order to facilitate the later maintenance of the equipment, and also save the space for installing the temperature detector 52 and the temperature control switch 53 on the pot cover, the latter is preferred in this embodiment.

[0053] The temperature control assembly 5 comprises a heating block 51, a temperature detector 52 and a temperature control switch 53. The heating block 51 is made of a heat-conducting material. The temperature detector 52 is preferably a temperature sensor, and is arranged on the heating block 51 and used for detecting the temperature of the heating block 51. One end of the heating wire 2 is connected to the heating block 51, and the heat emitted by the heating wire 2 can cause the temperature of the heating block 51 to rise. The temperature of the heating wire 2 is controlled by the control module to always remain within a preset range, so as to avoid affecting the refrigeration temperature in the reagent pot due to excessively high temperature, or causing condensate water on the surface of the pot cover due to excessively low heating temperature.

[0054] The temperature control switch 53 is connected in series with the heating wire 2. When the temperature of the heating wire 2 is out of control or the temperature detector 52 detects that the temperature of the heating block 51 is higher than a first preset temperature, the temperature control switch 53 can be disconnected, so that the heating wire 2 stops heating, thereby protecting the heating wire 2 and avoiding equipment damage caused by excessively high heating temperature. When the temperature detector 52 detects that the temperature of the heating block 51 is lower than a second preset temperature, the temperature control switch 53 is closed, and the heating wire 2 can heat again. The first preset temperature is greater than the second preset temperature.

[0055] The first side of the heating block 51 is provided with a mounting groove 511, and the temperature detector 52 and the temperature control switch 53 are arranged in the mounting groove 511. The second side of the heating block 51 is provided with a fixing groove 512, the fixing groove 512 extends in a meandering manner, and the heating wire 2 is arranged in the fixing groove 512 and extends along the extension direction of the fixing groove 512.

[0056] Reagent pot embodiment:

[0057] In combination Figure 2 And Figure 3 The reagent pot provided in the embodiment comprises a pot body 6, a second heat preservation layer 7 and the pot cover of the above-mentioned embodiments.

[0058] The second heat preservation layer 7 is arranged on the outer side of the pot body 6, and is made of a material with low thermal conductivity such as polystyrene or rubber sponge, so as to preserve heat of the pot body 6 and block the heat of the heating wire 2 from being conducted into the pot body 6. The pot cover is connected to the pot body 6 in a hinged manner, and a containing cavity for containing a reagent box is formed between the pot cover and the pot body 6. The pot cover can be hinged to the pot body 6 or detachably connected to the pot body 6, and the latter is preferred in the embodiment.

[0059] The upper portion of the pot body 6 is provided with a supporting portion 61, the edge portion 17 of the pot cover is arranged on the supporting portion 61, a blocking piece 8 is arranged between the edge portion 17 and the supporting portion 61, and the third arrangement section 23 located on the edge portion 17 is arranged above the blocking piece 8. The blocking piece 8 is made of plastic material and is used for preventing the heating wire 2 from being directly contacted with the pot body 6 to cause friction damage.

[0060] A sealing ring 9 is further arranged at the connection between the pot cover and the pot body 6, and extends along the circumference of the pot body 6, so as to prevent the cold air in the pot body 6 from leaking.

[0062] The analyzer provided in the embodiment comprises the reagent pot of the above-mentioned embodiments.

[0063] As can be seen from the above, the above-mentioned arrangement is beneficial to prevent condensate water from appearing around the sampling hole 13 and the door hole 11 and to prevent the condensate water from polluting the reagent.
