[0023] It is worth mentioning that, asFigure 2 As shown in the figure, the shell 1a is made of two left and right shells, the shell 1a is provided with a filling valve 1b for controlling communication and closing, the handle 3 includes a pressing part 3a and a hinged part 3b, the hinged part 3b is located in the shell 1a, the front end of the shell 1a is provided with a square hole 1a1, the square hole 1a1 is provided with a lead-in end 1a1a above, the lead-in end 1a1a is arc-shaped, the top of the pressing part 3a is provided with a slot 3a1 at the front end, the temperature measuring module 2 is provided with a clamping piece 2a below which can be elastically deformed, the clamping piece 2a can pass through the square hole 1a1 and the slot 3a1 in turn, and the clamping piece 2a and the bottom of the temperature measuring module 2 have a clamping gap.

[0024] As shown in the figure, Figure 3 and Figure 4 the filling valve 1b of the filler 1 is located in the middle of the shell 1a, the temperature measuring module 2 and the handle 3 are located in front of the filling valve 1b, and the detection table 4 is located at the rear end of the filling valve 1b, wherein the filling valve 1b is provided with a pressure detection port 1b1 at the rear end, an air outlet pipe at the front end and a valve core 1b2 at the middle, the pressure detection port 1b1 is electrically connected with the detection table 4, the handle 3 is divided into a pressing part 3a and a hinged part 3b, the hinged part 3b is located in the shell 1a, and the top of the hinged part 3b is provided with a top plate 3b1, one end of the top plate 3b1 is located above the valve core 1b2 of the filling valve 1b, the temperature measuring module 2 is located directly above the handle 3 and is arranged vertically with the axis of the valve core 1b2, and the pressure gauge is arranged obliquely with the axis of the valve core 1b2, wherein the top of the handle 3 is wrapped in the shell 1a.

[0025] More importantly, as shown in the figure, Figure 4 the front end of the shell 1a is provided with a square hole 1a1, the top of the pressing part 3a of the handle 3 is provided with a slot 3a1, the slot 3a1 is located behind the square hole 1a1, the clamping piece 2a passes through the square hole 1a1 and the slot 3a1 in turn, and the top plate 3b1 of the pressing handle 3 and the bottom of the containing groove 1a2 are clamped between the clamping gap.

[0026] In summary, the refrigerant filling device of the present application, when filling, the handle 3 at the front end of the filling is pressed, the valve core 1b2 in the filling valve 1b is driven to move downward, and then the refrigerant in the refrigerant tank is injected into the refrigerant equipment through the gas outlet pipe of the filling valve 1b, the hose 5 and the filling head 6, until the user observes the pressure at the pressure detection port 1b1 on the detection table 4 to be in the appropriate position, and stops filling. Wherein, on the basis of the prior art, a temperature measurement module 2 is arranged at the front end of the filler 1, after filling is completed, the temperature measurement module 2 is inserted into the air outlet of the air conditioner through the clamping space 2b between the clamping piece 2a and the bottom of the temperature measurement module 2, so that the temperature measurement module 2 can measure the temperature at the air outlet of the air conditioner and convert it into a digital signal to be sent to the detection table 4, and the current temperature is displayed on the detection table 4, so that the user can have a more intuitive understanding of the refrigeration effect of the air conditioner after filling. Wherein, in addition to being clamped on the blade of the air outlet of the air conditioner, the clamping piece 2a can be elastically deformed to a certain extent, so that in the non-use state, the clamping piece 2a can pass through the square hole 1a1 at the front end of the shell 1a, and the end of the temperature measurement probe 2c on the temperature measurement module 2 is embedded in the receiving groove 1a2.

[0027] It is worth mentioning that the handle 3 is provided with a through slot 3a1 for the clamping piece 2a to pass through. Since the handle 3 drives the hinge part 3b to rotate relative to the shell 1a through the pressing part 3a, and then presses the valve core 1b2, in the non-use state, the clamping piece 2a is inserted into the square hole 1a1 and the through slot 3a1 from front to back in sequence, and the top plate 3b1 of the handle 3 and the bottom of the receiving groove 1a2 are fixed in the clamping space 2b. When the handle 3 is swinging, interference will occur, which will prevent the handle 3 from being pressed downward, so that the refrigerant tank and the filling head 6 cannot be connected, and the accidental touch during use is avoided.

[0028] In addition, since the temperature measurement module 2 needs to be repeatedly inserted and pulled out, in order to avoid wear and tear of the side wall of the square hole 1a1 caused by repeated insertion and pulling out, which affects the clamping effect, a circular arc leading end 1a1a is arranged on the side wall above the square hole to avoid direct edge contact with the inner side of the clamping piece 2a to cause wear and tear, and to reduce the difficulty of insertion.
