[0025] In the present invention, the locking box body is fixedly installed below the bracket, and the supporting guide rail is fixedly installed above the bracket.

[0026] In the present invention, the rebound baffle has two positions: an initial position and an installation position. When the medicine tank is not installed, the rebound baffle is in the initial position. When the medicine tank is installed, the tank body is pushed in from one side of the support rail. The medicine tank pushes the rebound baffle, which simultaneously pushes the locking pin into the locking box. When the rebound baffle moves to the installation position, the locking pin automatically resets and inserts into a groove in the bottom plate of the medicine tank. The medicine tank is now locked and cannot be pulled out, and the proximity switch is triggered, indicating that the medicine tank is in the installed state. Pushing a button controls the locking pin to retract into the locking box.

The medicine tank can now be easily pulled out, and the proximity switch is turned off, indicating that the medicine tank is not installed. During operation, the electronically controlled evaporator automatically detects the status of the medicine tank. If it is in the installed state, the safety pin is automatically activated, locking the locking assembly and preventing the button from being pressed. This prevents the medicine tank from ejecting due to accidental activation of the reset switch during use, ensuring safety.

[0027] In the present invention, a circular mounting hole is provided in the center of the front of the locking box body. The button is coaxially mounted within the mounting hole and can move along the axis of the mounting hole. A square hole is provided in the center of the top plate of the locking box body. The locking pin is mounted within the square hole and can move along the axis of the mounting hole. A rectangular slot is provided at the rear of the top plate. The rebound baffle extends from the slot and can slide freely along the longitudinal direction of the slot.

[0028] In the present invention, the button and the locking pin can automatically pop out from their respective holes when in a free state.

[0029] In the present invention, the button and the locking pin are in a linkage relationship. When the button moves into its mounting hole, the locking pin is driven to move into the square hole.

[0030] In the present invention, the locking pin can move independently. When the pin head of the locking pin is pressed to move it from a free state into the square hole, the button does not move.

[0031] In the present invention, the rebound baffle has two positions: the tank-mounted position and the tank-unmounted position (initial position). A proximity switch monitors the rebound baffle's position. When the tank is removed, the rebound baffle automatically rebounds from the tank-mounted position to the tank-unmounted position, with the proximity switch providing feedback.

[0032] In the present invention, the safety pin is vertically arranged on one side of the button, pneumatic control is adopted, and the control interface is arranged at the bottom of the rear of the locking box body.

[0033] Compared with the prior art, the technical effects of the present invention are as follows:

[0082] In this embodiment,

[0083] Kinematic relationship of the safety pin assembly:

[0084] ① Free position: The air source pipe 22 is not ventilated, and the safety pin 23 is retracted into the safety pin installation cylinder 27 under the action of the return spring 25, and its top surface contacts the bottom surface of the head of the air source pipe 22.

[0085] ② Working state: The air source pipe 22 is ventilated. Under the action of the air source pressure, the safety pin 23 moves to the bottom along the safety pin installation cylinder 27. Its bottom surface contacts the first sealing ring. The head of the safety pin 25 extends out of the safety pin installation cylinder and is stuck in the step of the step button. At this time, the button 1 cannot be pressed and the locking device is locked to prevent accidental touch.

[0086] Kinematic relationship of the locking assembly:

[0087] ① Free position: The locking pin 9 is against the bottom of the locking device top plate 28-1, and the head of the locking pin 9 extends from the square hole of the locking device top plate. At the same time, the connecting rod 12 is pulled to drive the locking slider 4 to move left along the locking guide rail 5 to the right of the locking guide rail head bracket 2. The button 1 is linked and extends the locking device.

[0088] ② Pressing the head of the locking pin 9 can cause it to rotate counterclockwise along the locking pin shaft 8, driving the second connecting rod pin shaft 11 to slide along the sliding groove of the connecting rod 12, while the other parts remain stationary.

[0089] ③ Press button 1 to push the locking slider 4 and the first connecting rod pin 10 to move rightward along the locking guide rail 5, and drive the locking pin 9 to rotate counterclockwise through the connecting rod 12 and the second connecting rod pin 11, so that its head retracts into the locking device.

[0090] Kinematic relationship of the rebound component:

[0091] ① Free position: The rebound slider 16 is tightened against the limit nut 15 under the elastic force of the compression spring 17 , and the rebound baffle 18 moves to the initial position along with the rebound slider 16 .

[0092] ② Evaporator installation position: The evaporator pushes the rebound baffle 18 to move rightward to the installation position locking device housing as a limit for the rebound baffle 18, driving the rebound slider 16 to move rightward along the rebound guide rail 14 to the proximity switch 20. The proximity switch 20 is triggered to feedback the evaporator installation status.

[0093] The specific working principle of the locking device of the present invention is:

[0094] The locking box and the support rail are fixedly installed on the bracket. The medicine storage tank is pushed into the support rail and the locking box completes the locking action. The action process is as follows:

[0095] 1. If Figure 14-16 As shown, when installing the evaporator tank, align the groove at the bottom of the tank with the support rail and push it inward. The bottom of the tank presses the locking pin into the locking box. At the back of the tank, push the rebound baffle from the unmounted position to the mounted position. When the rebound baffle moves to the mounted position, the locking pin rebounds, and the pin head extends into the groove in the tank bottom plate, completing the locking action.

[0096] 2. When the evaporator is operating normally, the pneumatic safety pin rises, securing the button in its initial position to prevent accidental contact that could cause the tank to fall out and cause a dangerous situation. The proximity switch provides real-time feedback on the position of the rebound baffle, facilitating automatic control of the electronically controlled evaporator.

[0097] 3. If Figure 17-18 As shown, when the evaporator medicine storage tank is disassembled, press the button, the locking pin is linked and retracted into the locking box body, the pin head is separated from the groove at the bottom of the medicine storage tank, the rebound baffle rebounds to the position where the medicine storage tank is not installed, and at the same time pushes the medicine storage tank to pop out. At this time, the medicine storage tank can be easily taken out.

[0098] The present invention has an automatic pop-up structure for the medicine storage tank. The medicine storage tank is automatically popped out by pressing a button. The locking device has a built-in proximity switch, which can provide real-time feedback on the installation status of the medicine storage tank. The safety pin can automatically lock the self-resetting switch when the evaporator is running, making it invalid when the evaporator is in normal use, preventing accidental touch and ensuring safety during use.

[0099] Any content not described in detail in the present invention can be based on conventional technical knowledge in the art.

[0100] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
