Vacuum cleaner

The present invention relates to a dust suction device, and more particularly to a dust suction device for performing dust detection on a runner port.

Recently, with the continuous development and advancement of technology, many companies have invested a lot of resources in robot research and development and product development, which has led to the emergence of a variety of robot products of various uses, and is widely used in factory automation, hospital automation. , museum tours, surgical aids, space exploration, military applications, home services, office services, entertainment, and even the replacement of humans to perform dangerous tasks.

In the family service, the self-propelled device for cleaning the house, also known as the cleaning robot, is itself a kind of cleaning and vacuuming device, which can automatically move to the floor without the user's operation, and absorb the ground on the walking process. Dust and stand back to stand or charge. In addition, in the case of cleaning the dust suction device, in recent years, there has also been developed a dust suction device that is cleaned by hand, and its function and cleaning principle are similar to those of the self-propelled device.

In the case of the dust suction device, a dust box is installed inside the dust suction device for accommodating dust and dirt sucked during the cleaning. However, since the dust box is disposed inside the dust suction device, it is for the user. In other words, it is impossible to directly judge the amount of dust and dirt collected in the current dust box directly by the naked eye, so the user must disassemble the dust collecting device after a period of time. In order to confirm the collection amount of the dust box, it is possible to ensure that the dust suction device can continue to operate and effectively clean the dust, which is quite inconvenient for the user.

In addition, users are forgotten to check the dust and dirt collection in the dust box due to busy or negligent, resulting in the dust box not being effectively cleaned up in time, which will cause the suction port to block. This will also make dust collection. The cartridge continues to operate ineffectively, losing the function of the cleaning device to achieve cleaning and at the same time causing waste of electricity.

The following is a detailed description of the specific implementation of the present invention with reference to the accompanying drawings and embodiments. Step description. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and cannot limit the scope of protection of the present invention.

Figure 1 is a schematic view of the dust collecting device of the present invention. Figure 2 is a partial schematic view of the interior of the dust collecting device of the present invention. Figure 3 is a schematic diagram of the dust detection of the runner at the creation. Please refer to Figures 1 to 3. In the present embodiment, the dust suction device 100 includes a body 110, a dust box 120, a fan 130, and a detecting device 140.

The body 110 has two drive wheels 114 and a flow port 112 and a communication port.

The dust collecting box 120 is disposed in the body 110. The dust collecting box 120 has a dust collecting tube member 122. The dust collecting tube member 122 has a first end 122a and a second end 122b. The first end 122a of the dust collecting tube member 122 is located in the dust box. 120, the second end 122b of the dust suction pipe member 122 passes through the flow channel opening 112 and protrudes outside the body 110. The dust suction pipe member 122 acts as a dust suction device 100 to absorb dust when it is walking on the ground to clean the ground.

The fan 130 is disposed in the body 110, and the fan 130 is located beside the dust box 120. The fan 130 is configured to provide a wind flow to drive the dust suction tube 122 to absorb dust.

The detecting device 140 is disposed at the flow port 112, and the detecting device 140 is located at two sides of the dust collecting tube 122. The detecting device 140 includes a detecting component 142 and a lens assembly 144. The detecting component 142 has an infrared emitting element 142a and an infrared receiving element 142b.

The lens assembly 144 has a first lens 144a and a second lens 144b. The first lens 144a and the second lens 144b are respectively located on opposite sides of the flow channel opening 112, and the first lens 144a has a first cutting angle C1 at the front end. The front end of the second lens 144b has a second chamfer angle C2, and the first chamfer angle C1 and the second chamfer angle C2 face each other.

A first distance D1 is formed between the front end of the first corner C1 and the front end of the second chamfer C2, and a second distance D2 is formed between the rear end of the first chamfer C1 and the rear end of the second chamfer of C2. The first distance D1 is greater than the second distance D2. In other words, the spacing between the first chamfer angle C1 and the center of the runner opening 112 is tapered, and the spacing between the second chamfer angle C2 and the center of the runner opening 112 is tapered. Therefore, when the dust flows through the flow passage opening 112, the wind flow drives the dust from the hole between the front end of the first chamfer C1 and the front end of the second chamfer C2, even if the dust is driven by the wind flow to the front end of the first chamfer C1. Or the front end of the second chamfer angle C2, the dust can still be sucked along the shape of the first chamfer angle C1 or the second chamfer angle C2, so that the dust does not remain at the first chamfer angle C1 or the second chamfer angle On C2.

The first lens 144a is coated on the infrared ray emitting element 142a, and the second lens 144b is coated on the infrared ray receiving element 142b. In the present embodiment, the infrared ray emitting element 142a is parallel to the infrared ray receiving element 142b for emitting an infrared ray R1 and passing through the first chamfer angle C1 and the second chamfer angle C2 to the infrared ray receiving element 142b.

After the infrared ray R1 emitted by the infrared ray emitting element 142a passes through the first chamfer angle C1, the infrared ray R1 passes through the chute 112 and passes through the second chamfer angle C2 to receive the infrared ray receiving element 142b, so that the lens assembly 144 can provide and assist the infrared ray R1 to walk. Avoid the offset by the path to reduce the rate of detection of dust.

Thus, when the dust flows through the flow passage opening 112, the dust will block the infrared rays, and the infrared receiving element 142b transmits the signal received by the infrared receiving element 142b into a floating voltage signal, and the amount of the voltage signal is used to determine the amount of the dust. Further, the detection device 140 of the present invention can detect even finer particles through the analog signal processing, thereby improving the accuracy of the dust collecting device 100 for detecting the flow path dust.

In summary, in the dust suction device proposed by the present invention, it is at the runner Infrared detection is used to detect dust. Moreover, the present invention is designed by the chamfering of the lens assembly, which not only allows the infrared ray to the infrared ray receiving element emitted by the infrared ray emitting element to be guided, but also enhances the effect of detecting the dust, and since the front end of the lens is provided with a chamfering angle, To avoid dust residue on the lens.

The above descriptions are merely illustrative of the preferred embodiments or examples of the technical means employed to solve the problems, and are not intended to limit the scope of the invention. Any change or modification that is consistent with the scope of the patent application scope of this creation or the scope of the patent creation is covered by the scope of the creation patent.
