Detailed Description

As shown in fig. 1-6, the high pressure syringe with heating and heat preserving functions of the present invention comprises a main body 110, a supporting rod 120 and a chassis 130 connected in sequence from top to bottom, wherein a heating device 200 is provided at the front end of the main body 110. The heating device 200 is mainly divided into a heating mechanism 210 and a hinge mechanism 220, wherein the heating mechanism 210 includes an upper shell 211 and a lower shell 212, and two U-shaped grooves 213 with upward openings are formed in the middle of the upper shell 211. The both sides of the cylinder 300 are locked by the locking balls 214 so that the heating unit 200 can be positioned and fixed at a desired position. The upper shell 211 and the lower shell 212 are buckled with each other to form an inner cavity, the heating element 215 is arranged in the inner cavity below the U-shaped groove 213, and the upper end face of the heating element 215 is attached to the lower end face of the U-shaped groove 213. The U-shaped grooves 213 on the left and right sides can put down two syringes at the same time, so that the heating and heat-preserving efficiency of the syringe 300 is improved. Heating mechanism 210 is wrapping up cylinder 300 and can also make things convenient for the dismouting cylinder when playing fine heating and the heat preservation effect for the cylinder liquid medicine, has avoided the dismouting mode that the cylinder is interfered. The heating element 215 may be a resistive heating element or a heating film for heating and holding. The inner cavity is fixedly provided with a control main board 233 electrically connected with the heating element 215, and the control main board 233 is arranged in the middle of the heating mechanism 210 in a sheet shape.

The hinge mechanism 220 is disposed below the heating mechanism 210, and connects the heating mechanism 210 and the support rod 120. The movable end of the hinge mechanism 220 is fixedly connected to the heating mechanism 210, and the fixed end is fixedly connected to the host 110. The hinge mechanism 220 comprises a fixed end wire sheath 225, a fixed end rotating shaft member 224, a movable end rotating shaft member 222 and a movable end wire sheath 221; one end of the fixed end rotating shaft member 224 is fixedly arranged at the front end of the host 110, and the other end is rotatably connected with the movable end rotating shaft member 222; one end of the moving end rotating shaft member 222 is fixedly installed at the bottom end of the heating mechanism 210, and the other end is rotatably connected with the fixed end rotating shaft member 224; the fixed end cable sheath 225 is installed outside the fixed end rotating shaft member 224, and the movable end cable sheath 221 is installed outside the movable end rotating shaft member 222. The detection hole 226 is for infrared ray assisted detection, and is located above the middle of the fixed end rotating shaft member 224 for detecting whether the heating mechanism 210 is closed. When the heating mechanism 210 is closed, the slot of the heating mechanism 210 facing the host 110 is just locked into the fixed end rotating shaft member 224.

The damping module 223 is a damping rotary disc, which connects the fixed end and the movable end, so that the structure can rotate up and down. The vertical rotation can hover at any angle and cannot rotate and fall off under the action of the gravity of the vertical rotation. The rotation mode is more firm and safe. The inner cavity is further fixedly provided with a sensor unit 234 electrically connected with the control main board 233, the sensor unit 234 is an angle detection sensor for detecting the angle of the heating mechanism 210, and the syringe 300 can be better heated when the angle is adjusted to the correct position. The heating mechanism 210 is connected with the host 110 in a clamping or hinge manner, so that heating is facilitated. Details of the various components of the heating device 200 are shown in fig. 6.

When the heating mechanism 210 in the heating apparatus 200 is rotated, the sensor unit 234 may be a resistance heating element or a heating film, and the sensor unit 234 starts heating after sensing the syringe, otherwise the sensor unit 234 does not heat. The intelligent induction type heating and heat preservation is very convenient and safe.

As shown in fig. 7-12, the working principle of the high-pressure injector with heating and heat-preserving functions of the present invention is as follows:

as shown in fig. 7, the main body 110 faces the operator, and the horizontal heating device 200 is vertically downward through the hinge mechanism 220, so that the syringe 300 can be conveniently and subsequently placed in the main body 110. Fig. 8 is a partially enlarged view of the heating device 200 and the heating device 100 of fig. 7. As shown in fig. 8, the heating mechanism 210 is connected to the hinge mechanism 220, and the fixed end rotary shaft member 224 is opposite to the syringe 300, i.e., is to be placed into the main body 110; the fixed end rotating shaft member 224 is provided with a detection hole 226, and the detection hole 226 can assist in detecting whether the heating mechanism 210 is in a horizontal position or not by infrared. As shown in fig. 9, when the heating mechanism 210 is vertically downward, the syringes 300 are placed into the main unit 110 away from the opening of the U-shaped groove 213, and two syringes 300 can be placed into the main unit at the same time to improve the heating and heat preservation efficiency. As shown in fig. 10, the two syringes 300 have been placed into the main unit 110. Heating mechanism 210 is vertical downwards and is relatively convenient to dismouting cylinder 300, and cylinder 300 can not disturb the dismouting process. Fig. 11 is a partially enlarged view of the hinge mechanisms 220 and 230. As shown in fig. 11, the movable end waterproof joint 231 is provided to prevent the liquid medicine in the syringe 300 from flowing to the control main board 233; the lower case 212 protects the control main plate 233 from malfunction of the main plate 333 caused by the liquid medicine wetting 333 of the cylinder 300.

As shown in fig. 12, when the heating mechanism 210 is swung to the horizontal 90 degrees, the sensor unit 234 detects whether its angle is correct. When the angle is correct, after the infrared auxiliary detection of the detection hole 226 detects the heating mechanism 210, the heating mechanism 210 starts to work, and the heating element 215 automatically performs heating and heat preservation. The heating mechanism 210 can be used for better heating and insulating the syringe 300 by wrapping the syringe 300. When the syringe 300 needs to be taken out, the heating mechanism 210 is rotated to 90 degrees downward; finally, the syringe 300 is removed, and the heating mechanism 210 is returned to the horizontal position.

It will be apparent to those skilled in the art that various other changes and modifications may be made in the above-described embodiments and concepts and all such changes and modifications are intended to be within the scope of the appended claims.
