DETAILED DESCRIPTION

[0030] The preferred embodiments of the present application are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present application to illustrate the principles of the present application.

[0031] Example 1

[0032] This embodiment provides a dust-filled vacuum pressure detection tool, see Figures 1 to 5 , including a tube body 1 and an air inlet part and a vacuum pressure sensor 3 provided on the tube body 1. The air inlet part and the vacuum pressure sensor 3 are connected to the fluid channel in the tube body 1, and one end of the fluid channel is connected to the suction pipe 4 of the cleaning equipment.

[0033] When the cleaning device is in use, the top end of the detection tool is placed on the air inlet end of the cleaning device's suction pipe 4. The cleaning device's motor is turned on, and the external fluid enters the cleaning device through the air inlet and the fluid channel in the pipe body 1. After being filtered by the cleaning device's cyclonic separation component, dust and other particulate matter are placed in the dust collection cup. When the dust collection cup is full of dust, the fluid will still flow in the fluid channel. At this time, the gas pressure in the fluid channel detected by the vacuum pressure sensor 3 is the gas pressure value when the cleaning device is in the dust-full state.

[0034] Compared with the prior art, the dust-full vacuum pressure detection tooling provided in this embodiment is specifically used to detect the vacuum pressure of the cleaning equipment when the dust cup is full of dust. It can obtain the vacuum pressure of the cleaning equipment in the dust-full state, and then obtain the difference between the intake vacuum pressure values ​​of the cleaning equipment in the dust-full state and the non-dust-full state, and then judge the working performance of the motor of the cleaning equipment in the dust cup is full of dust. At the same time, once the motor is suffocated, the above-mentioned detection tooling can also obtain the vacuum pressure value of the motor in the suffocated state.

[0035] In addition, the above-mentioned detection tooling has a simple structure and occupies a small volume, so the inspectors of the cleaning equipment can conveniently detect the vacuum pressure of the cleaning equipment at any time.

[0036] Exemplarily, the air intake portion may include a main air intake hole 10 provided at the bottom end of the tube body 1 and an auxiliary air intake hole 11 provided on the side wall of the tube body 1, and the pressure sensor is provided on the side wall of the tube body 1. The aperture of the main air intake hole 10 is larger than the aperture of the auxiliary air intake hole, and the air intake volume of the main air intake hole 10 is larger than the air intake volume of the auxiliary air intake hole 11. This is because the air intake pipe 4 of the cleaning equipment is connected to the top end of the tube body 1, and the main air intake hole 10 is provided at the bottom end of the tube body 1. The gas entering from the main air intake hole 10 can enter the suction pipe 4 along a straight fluid path, thereby reducing the influence of fluid resistance on the vacuum pressure test results. At the same time, considering that the aperture of the main air intake hole 10 provided at the bottom end of the tube body 1 is limited, the provision of the auxiliary air intake hole 11 on the side wall of the tube body 1 can further increase the air intake volume of the above-mentioned detection tooling.

[0037] To further increase the air intake of the detection fixture, the auxiliary air intake hole 11 is located on the side of the vacuum pressure sensor 3 away from the main air intake hole 10. In other words, the auxiliary air intake hole 11 is located between the vacuum pressure sensor 3 and the suction pipe 4. This allows the auxiliary air intake hole 11 to be as close to the suction pipe 4 as possible, reducing the loss of fluid entering through the auxiliary air intake hole 11 and thus reducing the impact of fluid resistance on the air intake of the detection fixture.

[0038] In order to improve the detection accuracy of the above-mentioned detection tooling, the number of the above-mentioned vacuum pressure sensors 3 can be multiple, and the multiple vacuum pressure sensors 3 are arranged in a circumferential spiral along the inner wall of the tube body 1. This is because, due to the influence of fluid resistance, the flow velocity of the fluid will have a certain loss during the flow process. In other words, the vacuum pressure measured by the vacuum pressure sensor 3 at different positions on the side wall of the tube body 1 will also be different. The multiple vacuum pressure sensors 3 are arranged in a circumferential spiral along the inner wall of the tube body 1. It is possible to measure multiple vacuum pressure values ​​at the same time. The average vacuum pressure value can be obtained by taking the average of the multiple vacuum pressure values, which effectively reduces the influence of the setting position of the vacuum pressure sensor 3 on the vacuum pressure, thereby improving the detection accuracy of the above-mentioned detection tooling.

[0039] In order to enable the above-mentioned detection tooling to be used for the study of the influence of the detection position of the vacuum pressure sensor 3 on the vacuum pressure value, the above-mentioned detection tooling also includes a sleeve arranged on the inner wall of the tube body 1, and a plurality of detection holes are opened on the sleeve along the axial direction. The detection holes correspond one-to-one to the positions of the vacuum pressure sensor 3, and the corresponding detection holes and the vacuum pressure sensor 3 are located in the same radial section of the tube body 1.

[0040] For example, the pressure sensor may include a first pressure sensor, a second pressure sensor, and a third pressure sensor arranged in a circumferential spiral along the inner wall of the tubular body 1, and the detection holes may include a first detection hole, a second detection hole, and a third detection hole arranged axially along the casing. The first pressure sensor corresponds to the first detection hole and is located within a first radial cross-section of the tubular body 1, the second pressure sensor corresponds to the second detection hole and is located within a second radial cross-section of the tubular body 1, and the third pressure sensor corresponds to the third detection hole and is located within a third radial cross-section of the tubular body 1. When it is necessary to detect the vacuum pressure at the position where the first pressure sensor is located, the first pressure sensor is overlapped with the first detection hole, and the first pressure sensor is connected to the fluid channel in the tube body 1; when it is necessary to detect the vacuum pressure sensor 3 at the position where the second pressure sensor is located, the sleeve is rotated along the circumference of the sleeve so that the second pressure sensor is overlapped with the second detection hole, and the second pressure sensor is connected to the fluid channel in the tube body 1; similarly, when it is necessary to detect the vacuum pressure sensor 3 at the position where the third pressure sensor is located, the sleeve is rotated along the circumference of the sleeve so that the third pressure sensor is overlapped with the third detection hole, and the third pressure sensor is connected to the fluid channel in the tube body 1.

[0041] It is understandable that in order to enable the inspection personnel to understand the vacuum pressure of the cleaning equipment in a dust-filled state in real time, the above-mentioned inspection tooling also includes a display connected to the vacuum pressure sensor 3, which is used to display the vacuum pressure value collected by the vacuum pressure sensor 3.

[0042] During the vacuum pressure detection process, in order to prevent the suction pipe 4 from separating from the tube body 1, the above-mentioned detection tooling also includes an interface portion provided at the top of the tube body 1. The tube body 1 is connected to the suction pipe 4 of the cleaning equipment through the interface portion. The interface portion can increase the connection stability between the tube body 1 and the suction pipe 4 of the cleaning equipment, thereby preventing the suction pipe 4 from separating from the tube body 1.

[0043] Specifically, the above-mentioned interface part includes an interface tube 5 and an interface protrusion provided on the inner wall of the interface tube 5. The fluid enters the interface tube 5 from the air inlet end of the interface tube 5, and it will interact with the interface protrusion to generate a thrust from the air inlet end of the interface tube 5 to the air outlet end of the interface tube 5, so that the interface tube 5 and the tube body 1 are close to the suction pipe 4 of the cleaning equipment, thereby further increasing the connection stability between the tube body 1 and the suction pipe 4 of the cleaning equipment.

[0044] In order to improve the sealing performance of the connection between the interface portion, the pipe body 1 and the suction pipe 4, a sealing ring 6 is provided between the interface portion and the pipe body 1. For example, the pipe body 1 is sleeved on the outside of the mouthpiece 5, and the sealing ring 6 is sleeved on the outer wall of the bottom end of the mouthpiece 5, located between the pipe body 1 and the mouthpiece 5.

[0045] It can be understood that in order to prevent axial movement during the installation of the interface pipe 5, the outer wall of the above-mentioned suction pipe 4 is provided with a mounting groove for accommodating the sealing ring 6. The sealing ring 6 is located in the mounting groove, and the side wall of the mounting groove can limit the axial movement of the sealing ring 6.

[0046] In order to prevent the sealing ring 6 from falling out of the installation groove under the action of force during the installation of the interface pipe 5, an elastic retaining ring can be provided in the installation groove. During the installation of the interface pipe 5, when the inner wall of the pipe body 1 contacts the side of the sealing ring 6 away from the elastic retaining ring and applies a certain pressure, the side of the sealing ring 6 close to the elastic retaining ring is deformed under the action of pressure, so that the contact area and contact force between the sealing ring 6 and the elastic retaining ring are increased, thereby preventing the sealing ring 6 of the radial sealing device from falling out of the installation groove under the action of force; in addition, under the action of pressure, the sealing ring 6 can transmit the pressure to the elastic retaining ring, causing the elastic retaining ring to undergo a certain deformation and absorb a certain pressure, which is equivalent to reducing the pressure acting on the sealing ring 6, and can further prevent the sealing ring 6 of the radial sealing device from falling out of the installation groove under the action of force.

[0047] For example, within a mounting groove, there are one or two circlips. When there is one circlip, it is located on the side of the mounting groove close to the tube body 1. When there are two circlips, they are located on both sides of the mounting groove, with the sealing ring 6 located between the two circlips.

[0048] Example 2

[0049] This embodiment provides a device for detecting the vacuum pressure of a cleaning device. Figures 6 and 7 , including the dust-filled vacuum pressure detection tooling provided in Example 1 and a pressure stabilizing box 7 connected to the detection tooling. Specifically, the air outlet of the pressure stabilizing box 7 is connected to the air inlet of the detection tooling, and the pressure stabilizing box 7 is placed on the laboratory bench or the ground through a bracket.

[0050] Compared with the prior art, the beneficial effects of the dust-filled vacuum pressure detection device for cleaning equipment provided in this embodiment are basically the same as the beneficial effects of the dust-filled vacuum pressure detection tooling provided in Example 1, and are not described in detail here.

[0051] For different types of cleaning equipment, the size of the suction pipe 4 is also different. It can be understood that due to the simple structure and small size of the detection tooling, different types of cleaning equipment can be equipped with detection tooling of specific sizes during dust-filled vacuum pressure detection. However, due to the large size of the pressure stabilizing box 7, the size of the pressure stabilizing box 7 cannot be changed according to the type of cleaning equipment. In order to improve the adaptability of the above-mentioned pressure stabilizing box 7 and enable it to be suitable for the sizes of the suction pipes 4 of different types of cleaning equipment, the above-mentioned pressure stabilizing box 7 can be connected to the bottom end of the tube body 1 of the detection tooling through the box body connection part 8.

[0052] Specifically, the structure of the box connection portion 8 includes an adjustable clamp and a plurality of connectors arranged in an annular shape. The plurality of connectors are connected by the adjustable clamp to form an annular box connection portion 8. The box connection portion 8 is sleeved with the bottom end of the tube body 1. By adjusting the diameter of the adjustable clamp, the gap size between the plurality of connectors can be adjusted, thereby adjusting the diameter of the box connection portion 8, so that the box connection portion 8 can be fixedly connected to the bottom end of the tube body 1 of different sizes. It should be noted that the above-mentioned adjustable clamp refers to a clamp with an adjustable diameter. For example, the adjustable clamp can be a steel band clamp or a T-bolt clamp.

[0053] It is understandable that the box connecting portion 8 is used to connect the tube body 1 and the pressure stabilizing box 7. In order to achieve the connection between the box connecting portion 8 and the pressure stabilizing box 7, the box connecting portion 8 also includes a fastening screw, a sliding hole is provided on the connector, and a sliding groove is provided on the surface of the pressure stabilizing box 7. The bottom end of the fastening screw passes through the sliding hole and rests on the bottom of the sliding groove, thereby achieving a fixed connection between the box connecting portion 8 and the pressure stabilizing box 7. It should be noted that when the size of the tube body 1 needs to be changed, the fastening screw is first loosened to make the connector and the pressure stabilizing box 7 a sliding connection. Then, the diameter of the adjustable clamp is adjusted, and the multiple connectors are moved closer to or away from the center of the box connecting portion 8. The end of the tube body 1 is inserted between the multiple connectors. Then, the adjustable clamp and the fastening screw are tightened in sequence.

[0054] It is worth noting that the connection sealing between the box connecting part 8 and the tube body 1 will affect the vacuum pressure detection. In order to improve the connection sealing between the two, the above-mentioned box connecting part 8 also includes an elastic sealing body arranged between the connecting bodies. The shape of the elastic sealing body is also a fan ring. Multiple elastic sealing bodies and multiple connecting bodies are connected by adjustable clamps to form a ring-shaped box connecting part 8.

[0055] In order to be able to detect the effects of different air intake volumes on the dust-filled vacuum pressure of the cleaning equipment, the above-mentioned dust-filled vacuum pressure detection device for the cleaning equipment also includes a flow regulating component 9 connected to the pressure stabilizing box 7. Specifically, the air outlet of the flow regulating component 9 is connected to the air inlet of the pressure stabilizing box 7, and the flow regulating component 9 is used to adjust the fluid flow entering the pressure stabilizing box 7, thereby adjusting the air intake volume entering the cleaning equipment.

[0056] As for the structure of the flow regulating component 9, specifically, it includes a flow orifice 14 and a flow orifice mounting piece. The pressure stabilizing box 7 is fixedly connected to the external fluid pipeline 2 through the flow orifice mounting piece, and the flow orifice 14 is placed in the flow orifice mounting piece.

[0057] Exemplarily, the flow orifice mounting assembly includes a first joint 12 and a second joint 13, a flow orifice cavity is formed between the first joint 12 and the second joint 13, the first joint 12 is fixedly connected to the second joint 13 through a sliding assembly 15, and the first joint 12 can approach or move away from the second joint 13 along the axial direction of the flow orifice mounting assembly. Specifically, the first joint is fixedly connected to the fluid pipeline 2, and the second joint is fixedly connected to the pressure stabilizing box 7. The fluid enters the suction pipe 4 of the cleaning equipment through the fluid pipeline 2, the second joint 13, the flow orifice 14, the first joint 12, the pressure stabilizing box 7 and the pipe body 1 in sequence. When removing the flow orifice 14, the first joint 12 moves away from the second joint 13 through the sliding assembly 15, so that a gap is generated between the first joint 12 and the second joint 13. The flow orifice 14 can be taken out of the flow orifice cavity through the gap, completing the disassembly process of the flow orifice 14; when installing a new flow orifice 14, the new flow orifice 14 is placed into the flow orifice cavity through the gap, and the first joint 12 moves toward the second joint 13 through the sliding assembly 15, so that the first joint 12 and the second joint 13 are fixedly connected, completing the installation process of the flow orifice 14. In this way, the flow orifice 14 is installed between the pressure stabilizing box 7 and the fluid pipeline 2 through the first joint 12 and the second joint 13. Since the first joint 12 and the second joint 13 are fixedly connected by the sliding assembly 15, when replacing the flow orifice 14, it is only necessary to slide the second joint 13 away from the first joint 12 to create a gap between the two, so that the flow orifice 14 can be taken and placed, without removing the air flow channel from the pressure stabilizing box 7 body, thereby simplifying the replacement process of the flow orifice 14.

[0058] For example, the number of the above-mentioned sliding components 15 can be at least one. From the perspective of structural simplification, the number of sliding components 15 is one, which can be located at the upper end of the first joint 12 and the second joint 13. This is because the fluid pipeline 2 is heavy. When the first joint 12 and the second joint 13 are connected, under the action of the gravity of the air flow channel, the first joint 12 can be in close contact with the second joint 13, so that the flow orifice 14 is stably placed in the flow orifice cavity. From the perspective of structural stability, the number of sliding components 15 can be three, located at the upper end, left side, and right side of the first joint 12 and the second joint 13, respectively. Compared with setting up one sliding component 15, three sliding components 15 jointly support the first joint 12, which can reduce the shear force of the first joint 12 and the second joint 13 on the sliding component 15 and reduce the possibility of damage to the sliding component 15. In addition, as the number of bolts increases, it is easier to control the movement of the first joint 12.

[0059] Regarding the structure of the first joint 12 and the second joint 13, specifically, the first joint 12 includes a first tube and a first connecting ring provided at one end of the first tube, and the second joint 13 includes a second tube and a second connecting ring provided at one end of the second tube, and the first connecting ring is fixedly connected to the second connecting ring through a sliding assembly 15.

[0060] It should be noted that the first connecting ring can be provided at either end of the first tube, and the second connecting ring can also be provided at either end of the second tube. From an installation perspective, for example, the first connecting ring can be provided at one end of the first tube close to the second tube, with the other end of the second tube fixedly connected to the airflow channel, and the second connecting ring can be provided at one end of the second tube close to the first tube, with the other end of the first tube fixedly connected to the pressure stabilizing tank 7.

[0061] Regarding the structure of the sliding assembly 15, specifically, it includes a bolt 1501 and a nut 1502 that cooperates with the bolt 1501. The first joint 12 is fixedly connected to the second joint 13 through the bolt 1501. Specifically, the bolt 1501 passes through the first connecting ring and the second connecting ring and is connected with the nut 1502, so that the first joint 12 can move relative to the second joint 13 through the bolt 1501.

[0062] When the first joint 12 and the second joint 13 are fixedly connected, in order to reduce the axial and circumferential displacement of the two, a limiting assembly 16 for axially and circumferentially limiting the bolt 1501 can be provided between the bolt 1501 and the first connecting ring of the first joint 12. This is because, during use, the bolt 1501 and the nut 1502 may become loose, causing the first joint 12 to move away from the second joint 13, resulting in a gap between the two, and the flow orifice 14 is likely to fall out of the gap. The provision of the limiting assembly 16 can limit the bolt 1501 in the axial and circumferential direction, reduce the shaking of the bolt 1501, and further reduce the loosening between the bolt 1501 and the nut 1502, thereby improving the connection stability of the flow orifice mounting assembly.

[0063] For example, the above-mentioned limiting assembly 16 can be an elastic limiting assembly 16, including a spring and a locating pin, one end of the spring is fixedly connected to the first connecting ring of the first joint 12, and the other end is fixedly connected to the locating pin, and a locating groove for accommodating part or all of the locating pins is provided on the bolt 1501, and part or all of the locating pins are inserted into the locating groove. When the flow orifice 14 is removed, the first joint 12 moves away from the second joint 13 through the sliding assembly 15, so that a gap is generated between the first joint 12 and the second joint 13, the locating pin is disengaged from the locating groove, and the spring is in a compressed state; when a new flow orifice 14 is installed, the first joint 12 moves toward the second joint 13 through the sliding assembly 15, and the locating pin is inserted into the locating groove under the action of the spring rebound force, so that the second joint 13 can be axially and circumferentially positioned, reducing the shaking of the bolt 1501, and further reducing the loosening between the bolt 1501 and the nut 1502, thereby improving the connection stability of the above-mentioned flow orifice mounting component.

[0067] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in this application should be covered by the scope of protection of the present application.
