Description

Technical Field

[0001] The utility model belongs to dry cell resuscitation equipment, in particular to a cell resuscitation heating device with a multi-petal chuck. Background Art

[0002] The dry cell recovery instrument uses resistive heating elements as its core heating components. When powered, these elements generate heat, which is transferred to the cell sample through conduction or radiation, gradually raising its temperature to the set value.

[0003] Application number is a multi-petal chuck cell resuscitation heating device. It utilizes an axially split heat conducting tube with a tapered hole for cryotube insertion. A rotating shaft is inserted into the upper portion of each of the two heat conducting chucks, and a spring assembly is installed on the outer side of each of the two heat conducting chucks, allowing them to swing relative to each other around their respective rotating shafts. The spring assembly allows the two heat conducting chucks to clamp the cryotubes placed in the hole from both sides, thus meeting the varying sizes of cryotubes available on the market.

[0004] However, in actual use, it was found that the thermal chuck with the above-mentioned two-half structure still had poor fit with the cryopreservation tube, and the fact that only the lower part of the thermal chuck had left and right floating also limited its fit to a certain extent. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cell resuscitation heating device with a multi-petal chuck, wherein the heat conducting tube adopts an equally divided multi-petal chuck and can float radially to clamp the cryopreservation tube, thereby making it fit the cryopreservation tube more closely.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] Each spring assembly includes a first spring arranged between the outer wall of the thermal chuck and the inner wall of the shell, a waist-shaped hole vertically opened on the shell, and a guide screw with one end passing through the first spring and fixed on the outer wall of the thermal chuck and the other end passing through the waist-shaped hole.

[0010] The heating device also includes a freezing tube ejection mechanism, including a push rod that can move upward and extend from the bottom end of the freezing tube insertion hole, a second spring for pushing the push rod upward, and an electromagnetic latch mechanism for fixing the push pin to move downward.

[0021] like Figure 1 、 Figure 2As shown, a cell resuscitation heating device with a multi-petal chuck of the present invention is applied to a resuscitation instrument. In addition to the heating device of the present invention, the resuscitation instrument also includes a casing 1, a temperature control knob 2, and a temperature sensor installed in the thermal chuck 6 described below. The heating device is arranged in the casing 1, including a shell 3 and a heating element arranged in the shell 3. The heating element specifically includes a heat pipe 4 and a heating plate 5 circumferentially arranged on the outer wall of the heat pipe 4. A tapered cryotube insertion hole 11 is provided axially through the heat pipe 4. The difference is that the heat pipe 4 is equally divided into 3-6 independent thermal chucks 6 in the circumferential direction, and each thermal chuck 6 has a plurality of spring assemblies arranged in the vertical direction on the outside that can make the thermal chuck 6 radially floating and clamped.

[0022] The number of the thermally conductive chucks 6 can be three, four or more. Figure 1 The thermally conductive chuck 6 shown in FIG is divided into four equal parts, and each thermally conductive chuck 6 has two spring assemblies, which are respectively arranged at the upper and lower parts of the thermally conductive chuck 6. Of course, three or more spring assemblies can be arranged according to the longitudinal length of the thermally conductive chuck.

[0023] Each spring assembly includes a first spring 8 positioned between the outer wall of the thermal chuck 6 and the inner wall of the housing 3, a waist-shaped hole 12 vertically defined in the housing, and a guide screw 7, one end of which passes through the first spring 8 and is secured to the outer wall of the thermal chuck 6, with the other end extending through the waist-shaped hole 12. The upper and lower first springs 8 force the thermal chucks 6 radially inward, allowing the four thermal chucks 6 to be combined to form a tube. When a cryogenic tube 10 is inserted into the thermal tube 4 from above, the four thermal chucks 6 are pushed back and forth as they are inserted until they are fully inserted. Because the insertion hole formed by the four thermal chucks 6 matches the taper of the cryogenic tube 10, and due to the action of the first springs 8, the four thermal chucks 6 are able to maintain a constant grip and conform to the wall of the cryogenic tube 10. Due to the tapered shape of the cryogenic tube 10, as the thermal chucks 6 move radially back and forth, the guide screws 7 can move within their corresponding waist-shaped holes 12 within a certain arc, guiding the first springs 8.

[0024] Similarly, to enable the cryotube 10 to automatically eject after heating and resuscitation, making it easier to remove, the heating device of the present invention also includes a cryotube ejection mechanism. Specifically, it includes a push rod 9 that can be moved upward and extends from the bottom end of the cryotube insertion hole 11, a second spring 15 for pushing the push rod 9 upward, and an electromagnetic latch mechanism for securing the push rod downward. The push rod 9 is vertically arranged and, from top to bottom, includes an ejection section 91 for ejecting the cryotube 10, a tapered section 92 for separating the two thermal chucks 6, a stop step 93 for preventing the push rod 9 from further extending, and a lower section 94, the lower end of which extends through the bottom of the housing 3. The bottom of the housing 3 has a shaft sleeve 15 for vertically extending the lower section 94. The second spring 15 is mounted on the lower section 94 and abuts between the stop step 93 and the bottom of the housing 3. The lower section 94 also has a latch slot 95 that cooperates with the electromagnetic latch mechanism to lock.

[0025] The electromagnetic latch mechanism mainly includes a latch 16 , a third spring 13 driving the latch 16 to insert into the latch slot 95 , and an electromagnet 14 controlling the retraction of the latch 16 and compressing the third spring 13 .

[0026] The working principle of the cell resuscitation heating device with multi-petal chuck of the utility model is as follows:

[0027] Initially, the ejection section 91 and tapered section 92 of the ejector pin 9 both extend from bottom to top into the heat pipe 4 and are stopped by the stop step 93. The latch, under the elastic force of the third spring 13, presses against the outer wall of the lower section 94 below the latch slot 95. When the cryotube 10 is inserted into the heat pipe 4 from its upper end and moves downward against the ejector pin 9 until it is fully seated, the tapered section 92 is completely ejected from the heat pipe 4. The multiple thermal chucks 6 of the heat pipe 4, each under the elastic force of the first spring 8, clamp the cryotube 10, allowing the tapered cryotube insertion hole 11 formed by them to fully fit the cryotube 10. Simultaneously, the latch slot 95, which moves downward with the lower section 94, is locked by the latch 16, which is acted upon by the third spring 13, while the second spring 15 is compressed. At this point, heating by the heating plate 5 for a certain period of time can be performed to achieve resuscitation of the dry cells. After heating is completed, the electromagnet 14 is energized to suck the pin 16 back, and the ejector rod 9 is moved upward by the second spring 15, so that the ejection section 91 and the tapered section 92 are sequentially extended into the heat conduction tube 4, and the two heating blocks are swung open to both sides by the tapered section 92, while the cryotube 10 is pushed upward out of the heat conduction tube 4 by the ejection section 91.

[0028] However, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. Any changes or modifications to the above embodiments shall fall within the scope of the claims of the present invention as long as they are within the spirit of the present invention.
