Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum cleaners, and particularly relates to an air inlet structure of a vacuum cleaner with a built-in detection probe. Background Art

[0002] The working principle of a vacuum cleaner is that the motor drives the fan to rotate, generating negative pressure, so that the surrounding air and dust are sucked into the vacuum cleaner together. The sucked air separates dust and impurities through a filtration system, and then discharges the clean air outside the vacuum cleaner.

[0003] However, the existing vacuum cleaners have the problem of being unable to monitor the dust suction situation in real time. Due to the lack of a direct monitoring mechanism, it is impossible to timely understand the working state of the vacuum cleaner, such as whether the suction force weakens, whether the filter is blocked, etc. If these problems are not dealt with in time, it will further affect the dust suction effect of the vacuum cleaner, and may accelerate the wear of the vacuum cleaner due to overuse, shortening its service life. Summary of the Utility Model

[0004] The purpose of the utility model is to propose an air inlet structure of a vacuum cleaner with a built-in detection probe to solve the problem that the existing vacuum cleaners cannot monitor the dust suction situation in real time. Due to the lack of a direct monitoring mechanism, it is impossible to timely understand the working state of the vacuum cleaner, such as whether the suction force weakens, whether the filter is blocked, etc. If these problems are not dealt with in time, it will further affect the dust suction effect of the vacuum cleaner, and may accelerate the wear of the vacuum cleaner due to overuse, shortening its service life.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an air inlet structure of a vacuum cleaner with a built-in detection probe, including:

[0006] A vacuum cleaner body; an air inlet is provided thereon,

[0007] A visible probe housing; it is detachably connected to the air inlet, and a probe is arranged in the visible probe housing, and an air inlet housing is connected to the visible probe housing;

[0008] A protective shell; it is detachably connected to the periphery of the air inlet and sleeved on the visible probe housing and the air inlet housing.

[0009] As a further description of the above technical scheme:

[0010] A plurality of first mounting posts are arranged on the periphery of the air inlet, and a plurality of first mounting grooves are arranged on the periphery of the visible probe housing, and the first mounting grooves are clamped on the first mounting posts.

[0011] As a further description of the above technical scheme:

[0012] The tops and circumferences of several of the first mounting posts are provided with second mounting posts and clamping blocks, and the protective shell is provided with a second mounting groove and a clamping groove on the inner wall facing the air inlet. The second mounting posts and the second mounting grooves match each other, and the clamping blocks and the clamping grooves match each other.

[0013] As a further description of the above technical solution:

[0014] A piezoelectric sensor is arranged inside the visual probe housing.

[0015] As a further description of the above technical solution:

[0016] The visual probe housing, the air inlet and the air inlet housing are communicated with each other.

[0017] As a further description of the above technical solution:

[0018] The probe is a laser detection probe.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0020] 1. In the present utility model, by installing a visual probe housing at the air inlet of the vacuum cleaner body, a laser detection probe and a piezoelectric sensor are arranged inside it. The piezoelectric sensor is used to monitor the inhaled dust particles. When the dust particles impact the sensor, electrical signals will be generated. These signals are processed and converted into quantitative data of the dust. The laser detection probe forms a clear illumination area by emitting a laser beam and receiving the reflected light to realize the visualization of the dust. During the operation of the vacuum cleaner, the piezoelectric sensor and the laser detection probe will continuously send signals to the control system. When the laser detection probe detects a large amount of dust, the control system of the vacuum cleaner body may increase the suction of the vacuum cleaner; at the same time, the piezoelectric sensor will also monitor the inhaled dust amount in real time for more refined adjustment. This structure of the air inlet probe can monitor the dust quantity or concentration in the inhaled air flow in real time, enabling the vacuum cleaner to intelligently adjust the suction, and also avoiding problems such as blockage or excessive wear inside the vacuum cleaner, thereby improving the service life.
