Description

Technical Field

[0001] The utility model belongs to the field of suction testing devices, and particularly relates to a suction testing device for parts of a vacuum cleaner. Background Art

[0002] A vacuum cleaner mainly consists of three parts: dust raising, dust suction, and dust filtering. Generally, it includes a series-wound commutator motor, a centrifugal fan, a dust filter (bag), and a dust suction accessory. The power of a general vacuum cleaner is 400 - 1000 W or higher, and the power of a portable vacuum cleaner is generally 250 W and below. A vacuum cleaner can remove dust mainly because an electric exhaust fan is installed at its "head". There is an air impeller on the rotating shaft of the exhaust fan. After being powered on, the exhaust fan rotates at a speed of 500 revolutions per second to generate a relatively high suction force and pressure. Under the action of the suction force and pressure, air is discharged at high speed, and the air at the dust suction part in front of the fan continuously supplements the air in the fan, resulting in an instantaneous vacuum inside the vacuum cleaner and a negative pressure difference with the external atmospheric pressure. Under the action of this pressure difference, air containing dust is inhaled. Dust and other sundries pass through the carpet or floor brush, long connecting pipe, elbow pipe, hose, and hose connector into the dust filter bag in sequence. The dust and other sundries are retained in the dust filter bag. After the air is purified by the filter element, it is discharged from the tail of the machine body.

[0003] During the production process of a vacuum cleaner, in order to ensure that the vacuum cleaner has good dust suction ability, in the existing production of vacuum cleaners, due to the lack of an effective suction monitoring structure, it is very easy for the vacuum cleaner to have a deviation in dust adsorption during use due to too small suction force during production, which will affect the overall performance of the vacuum cleaner.

[0004] Therefore, in view of the deficiencies of the above solutions in actual production and implementation, they are corrected and improved. At the same time, with the spirit and concept of pursuing excellence, and with the assistance of professional knowledge and experience, and after various ingenious ideas and tests, the present utility model is created. A suction testing device for parts of a vacuum cleaner is provided specifically to solve the problem that in the existing production of vacuum cleaners, due to the lack of an effective suction monitoring structure, it is very easy for the vacuum cleaner to have a deviation in dust adsorption during use due to too small suction force during production, which will affect the overall performance of the vacuum cleaner.

[0024] As Figures 1 - 6 shown, a suction force testing device for vacuum cleaner parts includes: a side plate 3, the main body of the side plate 3 is longitudinally arranged, and the side plate 3 is fixedly connected to the top surface of the base 1, and a through hole is opened inside the side plate 3, a conduit 301 is embedded in the through hole, and the conduit 301 is a hollow tubular structure, and the conduit 301 is a right-side one-way opening structure. A flow concentrator 302 is fixedly connected to the right end surface of the conduit 301, and the main body of the flow concentrator 302 is a structure that is thinner on the left and thicker on the right. The conduit 301 communicates with the flow concentrator 302. A display screen 303 is fixedly connected to the front end surface of the flow concentrator 302, and the display screen 303 is a touch control structure. A tension sensor 304 is fixedly connected to the inside of the conduit 301, and a piston 305 is fixedly connected to the right side of the tension sensor 304. The piston 305 is slidably connected to the inside of the conduit 301. The conduit 301 and the piston 305 together form a pumping structure. A fixing bolt 204 is screwed into the internal threaded hole opened in the collar 203, and the main body 205 of the vacuum cleaner is clamped and limited inside the fixing bolt 204. The left opening of the main body 205 of the vacuum cleaner is inserted into the inside of the flow concentrator 302.

[0025] Among them, the main body of the base 1 is a rectangular frame structure, and a through hole is opened inside the base 1. This through hole is the mounting hole 101, and there are four mounting holes 101 in total. The four mounting holes 101 are respectively opened at the four corners inside the base 1. The mounting hole 101 and the base 1 together form a connection structure. A guide rail 102 is fixedly connected to the inside of the base 1, and the main body of the guide rail 102 is horizontally arranged. The guide rail 102 and the base 1 together form a support structure. A transverse groove is opened inside the guide rail 102, and an electric push rod 2 is installed in the transverse groove.

[0026] Among them, a moving seat 201 is installed on the left output end of the electric push rod 2, and the main body of the moving seat 201 is a rectangular block structure. A slider 202 is fixedly connected to the outside of the moving seat 201, and there are two sliders 202 in total. The two sliders 202 are respectively fixedly connected to the front and rear side surfaces of the moving seat 201. The moving seat 201 is slidably connected to the transverse groove opened in the guide rail 102 through the slider 202 fixedly connected to its outer side surface. A collar 203 is fixedly connected to the top surface of the moving seat 201. The main body of the collar 203 is an annular structure, and a screw hole is opened on the outer peripheral surface of the collar 203.

[0027] During use, when the suction of the vacuum cleaner is sampled, the sampled vacuum cleaner main body 205 can be inserted into the inner side of the collar 203 fixedly connected to the top surface of the moving seat 201, and the two fixing bolts 204 installed on the outer peripheral surface of the collar 203 can be manually held and inserted inward to synchronously position the vacuum cleaner main body 205 inserted into the collar 203.

During the air pumping process, the piston 305 installed in the conduit 301 can be adsorbed synchronously. When the piston 305 is adsorbed, the tension sensor 304 can be pulled synchronously. The tension sensor 304 is also called a resistance strain type sensor and belongs to the series of weighing sensors. It uses two force transmission parts to transmit force. Its structure contains a force-sensitive device and two force transmission parts. The force-sensitive device contains a piezoelectric sheet and a piezoelectric sheet gasket. The latter contains a substrate part and an edge force transmission part. Its characteristic is that the two ends of the two force transmission parts are fixed together, and the force-sensitive device is clamped by the transverse acting surface between the two ends. The piezoelectric sheet gasket is pressed on the central area of the piezoelectric sheet on one side. The substrate part is located on the other side of the piezoelectric sheet between the edge force transmission part and is in close contact with the piezoelectric sheet. One of its uses is to make a hook scale to replace the rod. Therefore, the tension received by the tension sensor 304 can be synchronously fed back to the display screen 303 arranged on the front end surface of the flow concentrating cover 302 for display.
