Description

Technical Field

[0001] The utility model belongs to dry cell resuscitation equipment, and particularly relates to a dry cell resuscitation heating device. Background Art

[0002] At present, dry cell resuscitators use resistance heating elements as the core heating components. After these elements are powered on, they generate heat, and transfer the heat to the cell sample by conduction or radiation, so that its temperature gradually rises to the set value.

[0003] In order to ensure uniform heating of the sample, dry cell resuscitators generally have a structure for uniform heating. For example, the heating elements are usually arranged around or at the bottom of the sample chamber, or materials with good thermal conductivity are used to evenly distribute the heat, avoiding local overheating or overcooling. However, due to the different model specifications of the cryotubes for storing dry cells on the market, the corresponding sizes are slightly different, so the existing resuscitation heating structure cannot ensure that the same heating element can completely fit each type of cryotube to achieve the best uniform heat distribution. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a dry cell resuscitation heating device, which can ensure the best uniform heat distribution through a floating heating element that can clamp and completely fit the cryotube.

[0005] In order to solve the above technical problem, the utility model adopts the following technical scheme:

[0006] A dry cell resuscitation heating device includes a housing and a heating element arranged in the housing. The heating element includes a heat conduction tube, heating sheets circumferentially arranged on the outer wall of the heat conduction tube. A tapered cryotube insertion hole is axially penetrated through the heat conduction tube, and the heat conduction tube is an axially split structure. Rotating shafts are respectively penetrated through the upper parts of the two split heat conduction blocks, and spring assemblies for relatively swinging and clamping the two heat conduction blocks around their respective rotating shafts are arranged on the outer sides of the lower parts of the two split heat conduction blocks.

[0007] The spring assembly includes a first spring arranged between the lower part of the heat conduction block and the inner wall of the housing, a kidney-shaped hole vertically opened in the lower part of the housing, and a guiding screw with one end passing through the first spring and fixed on the heat conduction block and the other end passing through the kidney-shaped hole.

[0008] The heating device further includes a cryotube ejecting mechanism, which includes a ejector rod that can move upward and extend into the bottom end of the cryotube insertion hole, a second spring for pushing the ejector rod upward, and an electromagnetic plugging mechanism for fixing the downward movement of the ejector pin. The ejector rod successively includes an ejection section for ejecting the cryotube from top to bottom, a conical section for separating the two heat conducting blocks, a stop step for stopping the continuous extension of the ejector rod, and a lower section that penetrates the bottom of the housing. The second spring is sleeved on the lower section and abuts between the stop step and the bottom of the housing. An insertion slot for cooperating with the electromagnetic plugging mechanism to lock is further provided on the lower section.

[0009] The electromagnetic plugging mechanism includes a plug, a third spring for driving the plug to insert into the insertion slot, and an electromagnet for controlling the retraction of the plug and compressing the third spring.

[0010] The dry cell resuscitation heating device of the present utility model has the following advantages:

[0011] 1. The heat conducting tube with an axial half structure is adopted, and a floating mechanism that can be clamped relatively left and right is formed through a spring assembly. A conical hole is adopted inside. When the cryotube is inserted from above, the two heat conducting blocks can automatically clamp the cryotube and ensure that its inner wall is completely attached to the cryotube.

[0012] 2. It is not necessary to fully adapt to the cryotube, and it can meet various cryotubes with different sizes in the market.

[0013] 3. When the cryotube is inserted, the electromagnetic plugging mechanism can automatically lock the downward moving ejector rod. After heating is completed, the plug can be reset by the electromagnet, and the ejector rod can automatically eject the cryotube.

[0014] 4. The ejector rod has a conical section, which can separate the two heating blocks to both sides when inserted, facilitating the removal of the cryotube. Description of the Drawings

[0020] A dry cell resuscitation heating device of the present utility model, as Figures 1-4 shown, includes a housing 1 and a heating element disposed inside the housing 1. The heating element specifically includes a heat conduction tube 2 and heating sheets 3 circumferentially arranged on the outer wall of the heat conduction tube 2. A tapered cryopreservation tube insertion hole 4 is axially formed through the heat conduction tube 2, and the heat conduction tube 2 is an axially split structure, that is, it is composed of two split heat conduction blocks 21 combined. Rotating shafts 8 are respectively inserted through the upper parts of the two heat conduction blocks 21, and both ends of the rotating shafts 8 are fixed to the housing 1. Spring assemblies for making the two heat conduction blocks 21 swing relatively around their respective rotating shafts 8 and clamp are arranged on the outer sides of the lower parts of the two heat conduction blocks 21. The design of the spring assemblies and the rotating shafts 8 enables the two heat conduction blocks 21 to have a structure that can float left and right.

[0021] Each spring assembly specifically includes a first spring 5 abutted between the outer wall of the lower part of the heat conduction block 21 and the inner wall of the housing 1, a kidney-shaped hole 6 vertically formed in the lower part of the housing 1, and a guiding screw 7 with one end passing through the first spring 5 and fixed on the heat conduction block 21 and the other end passing through the kidney-shaped hole 6. The two heat conduction blocks 21 can be relatively clamped by the first spring 5. When the two heat conduction blocks 21 overcome the clamping force and swing open in the reverse direction, the guiding screw 7 can swing in the corresponding kidney-shaped hole 6 and play a guiding role for the first spring 5.

[0022] In order to enable the cryopreservation tube 10 after heating and resuscitation to automatically pop out for convenient taking, the heating device of the present utility model further includes a cryopreservation tube ejecting mechanism, which specifically includes a top rod 9 that can move upward and extend into the bottom end of the cryopreservation tube insertion hole 4, a second spring 11 for pushing the top rod 9 to move upward, and an electromagnetic plugging mechanism for fixing the downward movement of the top pin. The top rod 9 is vertically arranged and successively includes a top ejection section 91 for ejecting the cryopreservation tube 10, a tapered section 92 for separating the two heat conduction blocks 21, a stop step 93 for stopping the continuous extension of the top rod 9, and a lower section 94 with the lower end passing through the bottom of the housing 1. The bottom of the housing 1 has a bushing 15 for the vertical passage of the lower section 94. The second spring 11 is sleeved on the lower section 94 and abutted between the stop step 93 and the bottom of the housing 1. An insertion slot 95 for cooperating with the electromagnetic plugging mechanism to lock is further arranged on the lower section 94.

[0023] The electromagnetic plugging mechanism mainly includes a plug 12, a third spring 13 for driving the plug 12 to insert into the insertion slot 95, and an electromagnet 14 for controlling the retraction of the plug 12 and compressing the third spring 13.

[0024] Initially, both the ejection section 91 and the conical section 92 of the ejector rod 9 extend into the heat conduction tube 2 from bottom to top and are stopped by the stop step 93. The latch is pressed against the outer wall of the lower section 94 below the latch groove 95 by the elastic force of the third spring 13. When the cryopreservation tube 10 is inserted into the heat conduction tube 2 from the upper end of the heat conduction tube 2 and abuts against the ejector rod 9 and moves downward until it is installed in place, the conical section 92 is just completely ejected from the heat conduction tube 2. The two heat conduction blocks 21 of the heat conduction tube 2 are respectively clamped against the cryopreservation tube 10 by the elastic force of the first spring 5, so that the tapered cryopreservation tube insertion hole 4 formed is completely fitted with the cryopreservation tube 10. At the same time, the latch groove 95 moving downward with the lower section 94 is locked by the latch 12 under the action of the third spring 13, and the second spring 11 is compressed. At this time, the dry cells can be revived by heating with the heating sheet 3 for a certain period of time. After heating, the latch 12 is sucked back by energizing the electromagnet 14, and the ejector rod 9 moves upward under the action of the second spring 11, so that the ejection section 91 and the conical section 92 extend into the heat conduction tube 2 in sequence. The two heating blocks are swung open to both sides by the conical section 92, and the cryopreservation tube 10 is ejected upward from the heat conduction tube 2 by the ejection section 91.

As long as it is within the scope of the substantial spirit of the present invention, changes and modifications to the above embodiments will fall within the scope of the claims of the present invention.
