Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaners, in particular to a dust content early warning device for a dust collecting bag based on a sensor. Background Art

[0002] A vacuum cleaner is mainly composed of three parts: dust collection, dust collection, and dust filtration. It generally includes a series commutator motor, a centrifugal fan, a dust filter (bag), and dust collection accessories. The power of a general vacuum cleaner is 400-1000W or higher, and the power of a portable vacuum cleaner is generally 250W or less. The vacuum cleaner can remove dust mainly because its "head" is equipped with an electric exhaust fan. There is a wind impeller on the rotating shaft of the exhaust fan. After power is turned on, the exhaust fan will generate high suction and pressure at a speed of 500 revolutions per second. Under the action of suction and pressure, the air is discharged at a high speed, and the air in the dust collection part at the front end of the fan continuously replenishes the air in the fan, causing an instantaneous vacuum inside the vacuum cleaner, forming a negative pressure difference with the external atmospheric pressure. Under the action of this pressure difference, dust-containing air is inhaled. The vacuum cleaner has a built-in dust bag to collect dust. When the dust bag is full, it will affect the dust collection efficiency. However, users often forget to check the dust bag during use. For this reason, a dust content warning device for the dust bag based on a sensor is proposed. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1 to Figure 3As shown, a dust content warning device of a dust bag based on a sensor includes a dust bag body 3, a positioning ring 1 is fixedly installed on the upper end of the dust bag body 3, a positioning bracket 2 is fixedly installed in the positioning ring 1, a detection mechanism 4 is arranged in the middle of the positioning bracket 2, the detection mechanism 4 includes a positioning seat 401, a detection spring 402, a spring seat 403, a detection support 404 and a detection pressure plate 405, and an early warning mechanism 5 is also arranged on the positioning bracket 2, and the early warning mechanism 5 includes a sensor mounting seat 501 integrally formed with the positioning bracket 2, a displacement sensor 502 mounted on the sensor mounting seat, and a sensor sheath 503 mounted on the displacement sensor 502. The detection mechanism 4 is mounted on the inner side of the positioning ring 1 through the positioning bracket 2.

[0018] A detection mechanism 4 is provided in the middle position of the positioning bracket 2, and the detection mechanism 4 includes a positioning seat 401, a detection spring 402, a spring seat 403, a detection pillar 404 and a detection pressure plate 405. The positioning seat 401 is fixedly installed on the positioning bracket 2, and a detection pillar 404 is movably installed on the positioning seat 401. The spring seat 403 is fixedly installed on the detection pillar 404. A detection spring 402 is sleeved on the detection pillar 404 above the spring seat 403, and a detection pressure plate 405 is fixedly installed on the lower end of the detection pillar 404. The detection spring 402 provides an upward elastic force for the detection pillar 404, thereby causing the detection pillar 404 to move upward.

[0019] A sensor mounting hole is provided at the upper end of the sensor mounting seat 501 , and the displacement sensor 502 is movably mounted on the sensor mounting seat 501 through the sensor mounting hole, and passes through the sensor mounting seat 501 to sense the displacement of the detection pillar 404 .

[0020] It should be noted that the utility model is a sensor-based dust bag dust content warning device. In actual use, the entire device is first installed in the dust bag body 3, and the diameter of the detection pressure plate 405 is slightly smaller than the inner diameter of the dust bag body 3, so that it can move in the dust bag body 3. Since an inlet and outlet hole is provided in the middle position of the positioning seat 401, the detection pillar 404 is movably installed on the positioning seat 401 through the inlet and outlet hole, one end of the detection spring 402 is connected to the bottom of the positioning seat 401, and the other end of the detection spring 402 is connected to the spring seat 403, and the detection pressure plate 405 is movably installed in the dust bag body 3 through the detection pillar 404. As dust falls on the detection pressure plate 405, more and more dust will fall, causing the detection pillar 404 to move downward. After the detection pillar 404 moves downward, the displacement sensor 502 senses the displacement signal of the detection pillar 404 and sends the signal to the main control system of the dust collecting equipment. The prompt module of the main control system reminds the user that the dust bag is fully loaded; in the utility model, the sensor mounting seat and the displacement sensor are movably connected through threads, so that the maintenance and debugging of the displacement sensor can be convenient; through the sensor sheath, dust is prevented from falling directly on the end of the displacement sensor, and the displacement sensor is protected.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
