Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which together with the embodiments of the invention serve to explain the principles of the invention.

Example one

The embodiment provides a dust fullness vacuum pressure detection tool, refer to fig. 1 to 5, including body 1 and the air inlet portion and the vacuum pressure sensor 3 of locating on body 1, air inlet portion and vacuum pressure sensor 3 communicate with the fluid passage in body 1, and the one end of fluid passage communicates with the suction pipe 4 of cleaning device.

When the cleaning equipment is used, the top end of the detection tool is sleeved on the air inlet end of the suction pipe 4 of the cleaning equipment, the motor of the cleaning equipment is started, external fluid sequentially enters the cleaning equipment through the air inlet part and the fluid channel in the pipe body 1, and after being filtered by the cyclone separation component of the cleaning equipment, particles such as dust and the like are placed in the dust collection cup. When the dust cup is in a dust-full state, the fluid still flows in the fluid channel, and the gas pressure in the fluid channel detected by the vacuum pressure sensor 3 is the gas pressure value of the cleaning device in the dust-full state.

Compared with the prior art, the dust full vacuum pressure detection tool provided by the embodiment is specially used for detecting the vacuum pressure of the cleaning equipment in the dust full state of the dust collection cup, can obtain the vacuum pressure of the cleaning equipment in the dust full state, further obtains the difference value of the air inlet vacuum pressure values of the cleaning equipment in the dust full state and the non-dust full state, and further judges the working performance of the motor of the cleaning equipment in the dust full state of the dust collection cup; meanwhile, once the motor is dead, the detection tool can also obtain the vacuum pressure value of the motor in the dead state.

In addition, the detection tool is simple in structure and small in occupied size, and detection personnel of the cleaning equipment can conveniently detect the vacuum pressure of the cleaning equipment at any time.

Exemplarily, the air inlet portion may include a main air inlet hole 10 disposed at a bottom end of the tube body 1 and an auxiliary air inlet hole 11 disposed on a side wall of the tube body 1, and the pressure sensor is disposed on the side wall of the tube body 1. Wherein, the aperture of the main air inlet hole 10 is larger than that of the auxiliary air inlet hole, and the air inflow of the main air inlet hole 10 is larger than that of the auxiliary air inlet hole 11. This is because the suction pipe 4 of the cleaning apparatus is connected to the top end of the pipe body 1, the main air inlet hole 10 is provided at the bottom end of the pipe body 1, and the gas entering from the main air inlet hole 10 can enter the suction pipe 4 along a straight fluid path, thereby reducing the influence of the fluid resistance on the vacuum pressure test result. Meanwhile, the air inflow of the detection tool can be further increased by considering that the aperture of the main air inlet 10 arranged at the bottom end of the tube body 1 is limited and the arrangement of the auxiliary air inlet 11 on the side wall of the tube body 1.

In order to further improve the air intake amount of the detection tool, the auxiliary air inlet 11 is disposed on a side of the vacuum pressure sensor 3 away from the main air inlet 10, that is, the auxiliary air inlet 11 is disposed between the vacuum pressure sensor 3 and the suction pipe 4. Therefore, the auxiliary air inlet holes 11 can be close to the suction pipe 4 as much as possible, the loss of fluid entering from the auxiliary air inlet holes 11 is reduced, and the influence of fluid resistance on the air inflow of the detection tool is reduced.

In order to improve the detection accuracy of the detection tool, the number of the vacuum pressure sensors 3 may be multiple, and the multiple vacuum pressure sensors 3 are spirally arranged along the circumferential direction of the inner wall of the pipe body 1. This is because, receive the influence of fluid resistance, the fluid has certain loss at the in-process velocity of flow, that is to say, vacuum pressure that vacuum pressure sensor 3 set up the different positions of surveying at body 1 lateral wall also can be different, the circumference spiral arrangement of a plurality of vacuum pressure sensors 3 along body 1 inner wall can survey a plurality of vacuum pressure values simultaneously, a plurality of vacuum pressure values are got the average and can be obtained average vacuum pressure value, effectively reduce the influence of vacuum pressure sensor 3 set position to vacuum pressure, thereby improve the detection accuracy of above-mentioned detection frock.

When the vacuum pressure at the position of the first pressure sensor needs to be detected, the first pressure sensor is superposed with the first detection hole and is communicated with the fluid channel in the pipe body 1; when the vacuum pressure sensor 3 at the position of the second pressure sensor needs to be detected, the sleeve is rotated along the circumferential direction of the sleeve, so that the second pressure sensor is superposed with the second detection hole, and the second pressure sensor is communicated with the fluid channel in the tube body 1; similarly, when the vacuum pressure sensor 3 at the position of the third pressure sensor needs to be detected, the sleeve is rotated along the circumferential direction of the sleeve, so that the third pressure sensor coincides with the third detection hole, and the third pressure sensor is communicated with the fluid passage in the pipe body 1.

It can be understood that, in order to enable the detection personnel to know the vacuum pressure of the cleaning device in the dust full state in real time, the detection tool further comprises a display connected with the vacuum pressure sensor 3 and used for displaying the vacuum pressure value collected by the vacuum pressure sensor 3.

In the vacuum pressure detection process, in order to avoid the separation of the suction tube 4 and the tube body 1, the detection tool further comprises a connector part arranged at the top end of the tube body 1, the tube body 1 is connected with the suction tube 4 of the cleaning equipment through the connector part, the connection stability between the tube body 1 and the suction tube 4 of the cleaning equipment can be improved through the connector part, and the separation of the suction tube 4 and the tube body 1 is avoided.
