After investigation, the current industry situation is to add a pressure transmitter to the main circulation water pipe of the equipment to monitor the main circulation pressure, but the pressure of the load rack loaded with the cleaning object cannot be effectively measured, which is precisely the link that most affects the cleaning effect.

It also includes a circulation pipeline 2, a circulation pump 3, a pressure transmitter 7 and a detection hose 8. The circulation pipeline 2 is connected to the cleaning machine 1 and supplies water to the water supply branch pipe 5. The circulation pump 3 is arranged on the circulation pipeline 2. One end of the detection hose 8 is connected to the pressure transmitter 7, and the other end is connected to the water supply branch pipe 5.

[0023] During the operation of the cleaning machine 1, the circulating pump 3 drives the cleaning water in the inner chamber through the circulating pipeline 2, and connects with the load rack 4 through the reserved docking port of the cleaning cabin, driving the spray arm 6 to rotate to clean the objects loaded on the load rack 4. The spray pressure of the spray arm 6 directly affects the cleaning effect of the object. The pressure detection device helps R&D personnel to monitor the internal pressure of the water supply branch pipe 5 on the load rack 4, providing quantitative data support for subsequent equipment optimization.

[0024] The quick connector 13 is connected to one end of the water supply branch pipe 5 near the spray arm 6. This position can more accurately reflect the water pressure of the spray arm 6, can accurately reflect the cleaning effect, and the data is more accurate and effective. The middle part of the detection hose 8 can be flexibly fixed at the supporting position of the load frame 4 to prevent the detection hose 8 from affecting the normal operation of the load frame 4.

[0025] See also Figure 2 In this embodiment, the pressure transmitter 7 is fixed to the upper part of the cleaning machine 1 through a fixing structure. Specifically, the fixing structure includes a through-wall joint 9 and a fastening nut 10. The lower part of the through-wall joint 9 is arranged in the cleaning machine 1, the upper end of the through-wall joint 9 extends upward from the cleaning machine 1 and is fixedly connected to the pressure transmitter 7, and the fastening nut 10 is arranged outside the cleaning machine 1 and is threadedly connected to the upper part of the through-wall joint 9.

[0026] A hose connector 12 is provided inside the lower part of the through-wall connector 9, one end of the detection hose 8 is fixedly connected to the hose connector 12, and the upper end of the hose connector 12 is sealed and connected to the lower part of the through-wall connector 9 and is connected to the pressure transmitter 7. In order to ensure that the connection between the through-wall connector 9 and the cleaning machine 1 is sealed reliably, a sealing gasket 11 is provided between the lower part of the through-wall connector 9 and the cleaning machine 1 in this embodiment.

[0027] See also Figure 3 The water supply branch pipe 5 is provided with a quick connector 13 for connecting the detection hose 8. The detection software is connected through the quick connector 13, which makes the connection more convenient and the detection efficiency higher.
