Embodiment 1

[0046] This embodiment provides a straight pipe with adjustable suction, see Figure 1 to Figure 6 , including a straight pipe body 2 and a suction adjustment assembly disposed on the inner wall of the straight pipe body 2, wherein the suction adjustment assembly includes a suction adjustment airbag 1 and an inflation and deflation assembly for inflating and deflation of the suction adjustment airbag 1. It should be noted that the suction regulating airbag 1 is an elastic airbag, and the volume of the suction regulating airbag 1 can be adjusted by adjusting the gas volume filled into the suction regulating airbag 1 .

[0047] When it is necessary to increase the suction in the straight pipe, open the inflation and deflation assembly to inflate the suction adjustment airbag 1, so that the volume of the suction adjustment airbag 1 increases, the radial cross-sectional area of ​​the straight pipe becomes smaller, and the flow rate remains basically unchanged. , the gas flow rate ...

Embodiment 2

[0059] The structure of the straight pipe with adjustable suction provided by this embodiment is basically the same as the structure of the straight pipe with adjustable suction provided by Embodiment 1, the only difference is that the air pressure sensor 6 is used instead of the suction gauge 55, see Figure 7 to Figure 8 , by measuring the gas pressure in the suction-adjusting airbag 1 and indirectly reflecting the volume of the suction-adjusting airbag 1, therefore, the above-mentioned straight pipe with adjustable suction can also include a processor 7, a suction-adjusting key 8 and a function for detecting the suction-adjusting airbag 1. The air pressure sensor 6 of the gas pressure, the processor 7 and the suction adjustment key 8 are all arranged in the main body of the vacuum cleaner, and the processor 7 can communicate with the suction adjustment key 8, The air pressure sensor 6, the air supply unit, the suction valve and the air discharge valve 4 are connected. When ...

Embodiment 3

[0063] This embodiment provides a method for adjusting the suction of a straight pipe. The straight pipe with adjustable suction provided in Embodiment 1 is used. When increasing the suction, the above-mentioned straight pipe suction adjustment method includes the following steps:

[0064] Step 1: Adjust the suction adjustment key, and the processor obtains the set suction value corresponding to the corresponding gear of the suction adjustment key;

[0065] Step 2: The processor controls the opening of the inflation and deflation component, and the inflation and deflation component fills the suction adjustment airbag with gas;

[0066] Step 3: The processor obtains the real-time suction value in the straight pipe body collected by the suction gauge in real time;

[0067] Step 4: The processor compares the real-time suction value with the set suction value in real time. When the real-time suction value is greater than or equal to the set suction value for the first time, the p...

Abstract

The invention discloses a straight pipe with the adjustable suction force, an adjustment method for the suction force of the straight pipe and a vacuum cleaner and belongs to the technical field of suction force adjustment equipment. The problems of a monotonous adjustment mode and poor accuracy of the suction force of the straight pipe in the prior art are solved. The straight pipe with the adjustable suction force comprises a straight pipe body and a suction force adjustment assembly arranged on the inner wall of the straight pipe body. The method comprises the following steps that a suctionforce adjustment key is adjusted, and a set suction force value corresponding to a corresponding gear of the suction force adjustment key is acquired; an air inflation and release assembly is controlled to be opened and injects air into a suction force adjustment airbag; a real-time suction force value or real-time pressure is acquired and compared with the set value; when the real-time suction force value or the real-time pressure is larger than or equal to the set value for the first time, the air inflation and release assembly is closed, and the suction force value in the straight pipe reaches the set suction force value. The straight pipe with the adjustable suction force can be applied to adjustment of the suction force of the vacuum cleaner.

Description

technical field [0001] The invention relates to a suction regulating device, in particular to a straight pipe with adjustable suction, a method for regulating the suction of the straight pipe, and a vacuum cleaner. Background technique [0002] In the prior art, when adjusting the suction force in the straight pipe, the area of ​​the pressure relief port covered by the flow element is usually adjusted by manually adjusting the outer wall of the straight pipe. This adjustment form is too simple and the accuracy is poor. Contents of the invention [0003] In view of the above analysis, the present invention aims to provide a straight pipe with adjustable suction, a straight pipe suction adjustment method, and a vacuum cleaner, which solves the problem that the suction adjustment form in the straight pipe in the prior art is too single and the accuracy is poor . [0004] The purpose of the present invention is mainly achieved through the following technical solutions: [00...
