[0026] Specifically, as shown in the figure, the pressure measuring channel group includes first pressure measuring channel 53, second pressure measuring channel 54, third pressure measuring channel 55 and fourth pressure measuring channel 55, wherein the first pressure measuring channel 53 is coaxially vertically arranged in the slide rod section 51, the second pressure measuring channel 54 is horizontally arranged in the slide rod section 51, the lower end of the first pressure measuring channel 53 is communicated with the pressure measuring nozzle 4, and the upper end is communicated with the middle part of the second pressure measuring channel 54;The third pressure measuring channel 55 is horizontally arranged in the adjusting section 52, and the fourth pressure measuring channel 55 is coaxially vertically arranged in the adjusting section 52, the lower end of the fourth pressure measuring channel 55 is communicated with the middle part of the third pressure measuring channel 55, and the upper end is communicated with the upper pressure measuring cavity 21.
[0027] Specifically, as shown in the figure, the first sealing ring 6 is sleeved on the slide rod segment 51, and the second sealing ring 7 is sleeved on the bottom of the adjusting segment 52, and when the pressure measuring rod 5 moves downward, the second sealing ring 7 is in contact with the lower sleeve shell 3, thereby sealing the gas or liquid flowing into the pressure measuring tool inside the pressure measuring tool.
[0028] Specifically, as shown in the figure, the reset spring 8 is arranged in the upper pressure measuring cavity 21, the upper end of the reset spring 8 is in abutment with the pressure gauge 1, and the lower end of the reset spring 8 is in abutment with the adjusting segment 52 of the pressure measuring rod 5, the reset spring 8 applies a downward pressure to the pressure measuring rod 5, and under normal conditions, the reset spring 8 drives the second sealing ring 7 to be in sealing contact with the lower sleeve shell 3.
[0029] Specifically, as shown in the figure, when the pressure measuring nozzle 4 is used for pressure measurement of an aerosol can product, the pressure measuring head is aligned with the aerosol valve and is pressed downward to make the pressure measuring nozzle 4 retract to the end, the adjusting segment 52 moves upward and abuts against the upper sleeve shell 2, at this time, the second pressure measuring channel 54 rises to the upper space of the lower pressure measuring cavity 31, the second pressure measuring channel 54 is in communication with the third pressure measuring channel 55, and the pressure gauge 1 performs pressure measurement.
[0030] Specifically, as shown in the figure, the upper sleeve shell 2 and the lower sleeve shell 3 are in threaded connection, and the upper sleeve shell 2 and the pressure gauge 1 are in threaded connection.
[0031] Specifically, the specific implementation principle of the utility model is:
[0032] Before pressure measurement, the pressure measuring rod 5 is kept in a pressed state under the action of the elastic force of the reset spring 8. At this time, the second sealing ring 7 on the adjusting segment 52 is in close contact with the lower sleeve shell 3, forming a seal, so that the gas or liquid in the pressure measuring tool cannot leak. The first pressure measuring channel 53 and the second pressure measuring channel 54 are independent of each other in the slide rod segment 51, and the third pressure measuring channel 55 and the fourth pressure measuring channel 56 are also independent of each other in the adjusting segment 52.
[0033] The pressure measuring nozzle 4 is aligned with the aerosol valve of the aerosol can, and the pressure measuring rod 5 is pressed downward, so that the pressure measuring nozzle 4 retracts to the end. At this time, the adjusting segment 52 moves upward and abuts against the upper sleeve shell 2. During the downward pressing of the pressure measuring rod 5, the first sealing ring 6 ensures the sealing between the slide rod segment 51 and the lower pressure measuring cavity 31, so as to prevent gas or liquid from leaking.
[0034] When the pressure measuring nozzle 4 is fully pressed into the aerosol valve, the rising of the adjusting section 52 causes the second pressure measuring channel 54 (horizontally arranged) to enter the upper space of the lower pressure measuring cavity 31 and communicate with the third pressure measuring channel 55 in the upper space. At the same time, due to the close connection of the pressure measuring nozzle 4 and the aerosol valve, the gas or liquid in the aerosol can enters the first pressure measuring channel 53 through the pressure measuring nozzle 4, then passes through the second pressure measuring channel 54, the third pressure measuring channel 55, and finally enters the upper pressure measuring cavity 21 through the fourth pressure measuring channel 55.
[0035] When the pressure measuring channel group is fully connected, the pressure of the gas or liquid in the aerosol can is transmitted to the pressure gauge 1 through the pressure measuring channel, and the pressure gauge 1 displays the current pressure value. Due to the elastic force of the reset spring 8, the pressure measuring rod 5 always maintains close contact with the aerosol valve, ensuring the stability and accuracy of the pressure measuring process.
[0036] After the pressure measurement is completed, loosen the pressure measuring rod 5, and the elastic force of the reset spring 8 pushes the pressure measuring rod 5 back to the initial state. During the rising of the pressure measuring rod 5, the second sealing ring 7 again closely contacts with the lower sleeve 3, forming a seal to prevent the gas or liquid in the pressure measuring tool from being sprayed out during separation. At the same time, due to the special design of the pressure measuring channel group, even if the pressure measuring rod 5 is separated from the aerosol valve, the pressure measuring channel will automatically close, ensuring that the pressure in the pressure measuring tool will not be suddenly released, thereby effectively preventing the occurrence of the splashing phenomenon.
[0037] The pressure measuring tool is not limited to the pressure measurement of female valve aerosol cans. When needed, only the corresponding pressure measuring head needs to be replaced to realize the pressure measurement of different specifications of female and male valves. The pressure measuring tool has remarkable anti-splashing effect, effectively avoids the liquid in the aerosol can product from being splashed onto the product or onto the worker operating it, and saves the time of cleaning the product.
[0038] The utility model proposes a kind of anti-splashing aerosol can pressure measuring tool, and pressure measuring function is realized by upper sleeve, lower sleeve and coaxial sliding pressure measuring rod of detachable connection, and pressure measuring channel group is equipped in pressure measuring rod, and passage opening and closing are controlled by adjusting pressure measuring rod position.The tool structure is reasonable, easy to operate, can effectively seal the gas or liquid in the internal during pressure measurement, prevent splashing, and the design of reset spring and sealing ring ensures the accuracy and safety of measurement.Screw connection is used between upper sleeve and pressure gauge and upper sleeve, easy to disassemble and maintain, improve the practicability and durability of tool.
