When the floor is cleaned by using the cleaning equipment, whether the floor is clean or not is difficult to judge, and a cleaning person is usually required to observe through human eyes to judge. In order to solve the problem, an induction device is additionally arranged on an air duct of the cleaning device to identify the amount of dust sucked from the ground, specifically, when the amount of dust in the air duct is large, the transmittance of the air duct is lower, the total amount of light energy emitted by an emitter of the induction device is smaller, when the amount of dust on the ground is gradually reduced, the amount of dust entering the air duct in the later stage of cleaning is smaller, the transmittance of the air duct is higher, then the total amount of light energy emitted by the emitter of the induction device is larger, the total amount of light energy received by the receiver is compared in real time, and when the total amount of light energy received by the receiver is in an ascending trend and is finally maintained at a certain value, the cleaning degree of the ground is higher.

Currently, the transmitter and the receiver of the sensing device are respectively arranged at two opposite sides of the sewage pipe channel. Because dirty pipe wall thickness is thicker, has the dispersion effect to the light beam that the transmitter sent to and, clean setting is when using, and the dirty pipe easily appears the condition such as shake, consequently, the receiver easily appears receiving the light beam that the transmitter sent, makes induction system appear erroneous judgement.

In view of this, an embodiment of the present utility model provides a cleaning apparatus, in which a first light-focusing structure is formed on a suction pipe, and the first light-focusing structure is used for focusing a light beam, so that the light beam emitted by an emitter can be focused, or the light beam received by a receiver can be focused, so that the total light transmission amount is increased, and the misjudgment rate of a sensing device is reduced.

Referring specifically to fig. 1 and 2, a cleaning apparatus according to an embodiment of the present utility model includes a suction assembly 10 and a sensing device 20.

The suction assembly 10 is used for sucking dust on the floor to be cleaned, one end of the suction assembly is communicated with the floor sweeping assembly of the cleaning device, and the other end of the suction assembly is communicated with the air duct of the cleaning device.

The suction assembly 10 comprises a suction duct 11. Here, the suction duct 11 is an intermediate duct that communicates the floor sweeping assembly with the air duct.

The sensing device 20 comprises a transmitter 21 and a receiver 22. The suction duct 11 has a first condensing structure 30 formed on a peripheral side wall thereof, the emitter 21 and the receiver 22 are oppositely disposed on the peripheral side wall of the suction duct 11, and one of the emitting end of the emitter 21 or the receiving end of the receiver 22 corresponds to the first condensing structure 30.

The transmitter 21 is for transmitting the beam energy and the receiver 22 is for receiving the beam energy. The emitter 21 and the receiver 22 are oppositely arranged on the peripheral side wall of the suction pipeline 11, and the connection line of the emitting end of the emitter 21 and the receiving end of the receiver 22 penetrates through the suction channel. Alternatively, the connection line of the transmitting end of the transmitter 21 and the receiving end of the receiver 22 penetrates the center line of the suction channel, that is, the distance between the transmitting end of the transmitter 21 and the receiving end of the receiver 22 is the largest, so that the space of the radial range of the suction duct 11 can be covered, that is, the real situation of the floor cleanliness can be reflected to the maximum.

Here, the shape and structure of the first light collecting structure 30 are not limited, and may be any shape and structure that can realize a light collecting function.

For example, the first light-focusing structure 30 may be a concave structure or a convex structure, taking the forward direction as an example that the transmitting end of the transmitter 21 points to the receiving end of the receiver 22, when the transmitting end of the transmitter 21 corresponds to the first light-focusing structure 30, the first light-focusing structure 30 is concave along the forward direction to form a concave structure, so as to focus the emitted light beam; when the receiving end of the emitter 21 corresponds to the first light focusing structure 30, the first light focusing structure 30 protrudes in a direction away from the forward direction to form a convex structure, so as to focus the received light beam.

The first light focusing structure 30 may also be, for example, a cone structure, i.e. focusing the light beam with its cone, and as such, the direction of propagation of the light beam can be adapted to focus the emitted light beam or to focus the received light beam by arranging the cone structure in a forward direction or in a reverse direction.

And, the first light focusing structure 30 may be an additional solid structure, or may be a virtual structure formed by recessing the peripheral sidewall of the suction duct 11.

According to the cleaning device provided by the utility model, the first light focusing structure 30 is formed on the peripheral side wall of the suction pipeline 11, and the first light focusing structure 30 is used for focusing the light beams, both the light beams emitted by the emitter 21 and the light beams received by the receiving end can be converged, so that the total amount of light energy received by the receiving end of the sensing device 20 is increased, and the misjudgment rate of the cleaning device in detecting the real-time dust collection amount is reduced.

Referring to fig. 1 and 2, in one embodiment, the second light condensing structure 40 is formed on the peripheral sidewall of the suction duct 11, and the receiving end of the receiver 22 or the emitting end of the emitter 21 corresponds to the other second light condensing structure 40.

Here, the shape and structure of the second light condensing structure 40 are not limited, and may be any shape and structure capable of realizing a light condensing function. Of course, the shape and structure of the second light focusing structure 40 may be the same as or different from that of the first light focusing structure 30.

For example, the second light-focusing structure 40 may be a concave structure or a convex structure, taking the forward direction as an example that the transmitting end of the transmitter 21 points to the receiving end of the receiver 22, when the transmitting end of the transmitter 21 corresponds to the second light-focusing structure 40, the second light-focusing structure 40 is concave along the forward direction to form a concave structure, so as to focus the emitted light beam; when the receiving end of the emitter 21 corresponds to the second light focusing structure 40, the second light focusing structure 40 protrudes in a direction away from the forward direction to form a convex structure, so as to focus the received light beam.

The second light focusing structure 40 may also be, for example, a cone structure, i.e. focusing the light beam with its cone, as such, the direction of propagation of the light beam can be adapted by a forward or reverse arrangement of cone structures to focus the emitted light beam or to focus the received light beam.

And, the second light condensing structure 40 may be an additional solid structure or a virtual structure formed by recessing the peripheral sidewall of the suction duct 11.

Specifically, as shown in fig. 2, the first light condensing structure 30 and the second light condensing structure 40 are both virtual structures, and the shape structure of the first light condensing structure 30 and the shape structure of the second light condensing structure 40 are the same, and are both concave structures, taking the forward direction as an example where the transmitting end of the transmitter 21 points to the receiving end of the receiver 22, the first light condensing structure 30 is a concave structure formed by recessing the peripheral side wall of the suction duct 11 in the forward direction, and the second light condensing structure 40 is a concave structure formed by recessing the peripheral side wall of the suction duct 11 in the direction away from the forward direction, and at the same time, the dimensions of the two concave structures are equal, for example, the inner diameter of each place of the concave structures, and the depth thereof are equal.

Specifically, in one embodiment, the first light gathering structure 30 and/or the second light gathering structure 40 are spherical grooves.

Here, in the present embodiment, the first light condensing structure 30 is a spherical groove; alternatively, the second light focusing structure 40 is a spherical groove; alternatively, the first light focusing structure 30 and the second light focusing structure 40 are spherical grooves. It can be understood that the inner wall of the spherical groove is of a spherical structure, and the spherical structure has better effect of condensing or converging the light beam.

For example, taking the forward direction of the emitting end of the emitter 21 pointing to the receiving end of the receiver 22 as an example, when the first light focusing structure 30 is a spherical groove, the spherical groove is a groove formed by recessing the peripheral side wall of the suction pipe 11 along the forward direction; when the second light collecting structure 40 is a spherical groove, the spherical groove is a groove formed by recessing the peripheral side wall of the suction duct 11 in a direction away from the forward direction.

Referring to fig. 2, in one embodiment, the suction duct 11 is made of a light-transmitting material, and the wall thickness of each of the first light-condensing structure 30 and the second light-condensing structure 40 is smaller than the average wall thickness of the suction duct 11.

Here, the light-transmitting material is a material that transmits light, for example, transparent plastic, transparent resin, or the like. The suction duct 11 of transparent material is transparent to the light beam at the emitting end of the emitter 21 and is finally received by the receiving end of the receiver 22.

And, the first light condensing structure 30 and the second light condensing structure 40 are both virtual body structures concavely formed at the peripheral side wall of the suction duct 11 such that the wall thickness of the suction duct 11 at the first light condensing structure 30 and the second light condensing structure 40 is smaller than the average wall thickness of the suction duct 11. In this way, the transmitting end of the transmitter 21 may be disposed closer to the peripheral side wall of the suction duct 11, and the receiving end of the receiver 22 may be disposed closer to the peripheral side wall of the suction duct 11, and then the distance of the connecting line of the transmitting end of the transmitter 21 and the receiving end of the receiver 22 may be shortest.

Referring to fig. 1 and 2, in one embodiment, the cleaning apparatus further includes a fixing assembly 50, where the fixing assembly 50 includes a fixing frame 51 surrounding a peripheral sidewall of the suction duct 11, and two cover plates 52, the fixing frame 51 has two accommodating cavities 50a for accommodating the emitter 21 and the receiver 22, respectively, and each cover plate 52 covers an opening end of the corresponding accommodating cavity 50a to limit-fix the emitter 21 and the receiver 22.

It will be appreciated that during cleaning, the fan of the cleaning apparatus vibrates to drive the other components to vibrate synchronously, so that during synchronous vibration, the emitter 21 and the receiver 22 may move relatively to the suction duct 11, which eventually results in a lack of light signal reception.

Here, the fixing component 50 is used for fixing and limiting the emitter 21 and the receiver 22, so as to reduce the probability of relative movement of the emitter 21 and the receiver 22 relative to the suction duct, and improve the reliability of signal transmission of the sensing device 20.

For example, the fixing frame 51 and the circumferential side wall of the suction duct 11 may be integrally connected, so as to improve the synchronous vibration of the transmitter 21 and the receiver 22 and the suction duct 11 and reduce the probability of occurrence of relative movement. Alternatively, the fixing frame 51 may be connected to the peripheral wall of the suction duct 11 by a screw connection, a socket connection, a snap connection, or the like.

The emitter 21 and the receiver 22 are respectively limited in the corresponding accommodating cavities 50a, and the limiting form of the emitter 21 and the receiver 22 in the accommodating cavities 50a is not limited. For example, the inner shape of the accommodating cavity 50a is adapted to the outer shapes of the emitter 21 and the receiver 22, that is, the emitter 21 and the receiver 22 are directly clamped in the corresponding accommodating cavity 50a, the cover plate 52 is used for placing the emitter 21 and the receiver 22 out of the opening end of the accommodating cavity 50a, or corresponding limiting structures are arranged in the accommodating cavity 50a, and the emitter 21 and the receiver 22 are limited and fixed through the limiting structures.

Specifically, referring to fig. 1 and 2, in one embodiment, the fixing assembly 50 further includes a first positioning post 53 disposed in the accommodating cavity 50a, and a second positioning post 54 disposed on the cover plate 52 and corresponding to the first positioning post 53, and the transmitter 21 and the receiver 22 are sandwiched between the corresponding first positioning post 53 and second positioning post 54.

It will be appreciated that when the cover plate 52 is disposed over the open end of the receiving cavity 50a, the first positioning post 53 and the second positioning post 54 are opposite, i.e. the central axes of the two should be coincident or substantially coincident, so that a clamping force can be applied to the transmitter 21 or the receiver 22 by the first positioning post 53 and the second positioning post 54 to fix the transmitter 21 and the receiver 22 in the receiving cavity 50 a.

Here, the cover body and the fixing frame 51 may be fixedly connected by a fastener, or may be connected by a clip connection or a plug connection.

For example, the cover body and the fixing frame 51 may be fixedly connected by using screws, and threaded holes may be respectively formed on the first positioning column 53 and the second positioning column 54 for the screws to pass through.

Specifically, referring to fig. 1 and 2, in one embodiment, the first positioning post 53 is formed with a protrusion 55, and the transmitter 21 and the receiver 22 are formed with a recess 56 adapted to the protrusion 55.

Here, the convex portion 55 may be a boss, a convex bone, or the like, and the concave portion 56 may be a groove, an opening, or the like. Then, before the preparation for the installation, the emitter 21 and the receiver 22 are set on the first positioning post 53, at this time, the convex portion 55 is fitted with the concave portion 56, that is, the emitter 21 and the receiver 22 may be temporarily connected with the first positioning post 53 to achieve the preliminary positioning, and then the second positioning post 54 is abutted with the first positioning post 53 by the cover plate 52 to completely limit the emitter 21 and the receiver 22.

Illustratively, the protrusion 55 is a boss formed on the first positioning post 53 and the recess 56 is a groove formed by inward depression of the side wall of the transmitter 21 or receiver 22. The shape of the notch of the groove is matched with the outline of the boss, so that one or more first positioning columns 53 are arranged at the same time, and the requirement of preliminary positioning of the emitter 21 or the receiver 22 can be met.

Referring to fig. 1, in one embodiment, the second positioning post 54 is provided with a avoidance structure 57 for avoiding the transmitter 21 and the receiver 22.

Here, the avoidance structure 57 serves to prevent structural interference of the transmitter 21 or the receiver 22 on the mounting. For example, the relief structure 57 may be a notch or slot formed in the second positioning post 54, and the space formed by the notch or slot may accommodate the transmitter 21 and the receiver 22.

Referring to fig. 1, in one embodiment, the fixing assembly 50 further includes two pipe columns 58 for limiting the transmitting end of the transmitter 21 or the receiving end of the receiver 22, and each pipe column 58 is formed in the accommodating cavity 50 a.

It will be appreciated that the transmitting end of the transmitter 21 or the receiving end of the receiver 22 are protruding portions, which are adapted to the inner space of the tube, i.e. the inner diameter of the tube is adapted to the outer diameter of the transmitting end of the transmitter 21 or the receiving end of the receiver 22, so as to further increase the number of connection sites between the transmitter 21 or the receiver 22 and the fixing frame 51, thereby further improving the connection stability of the transmitter 21 or the receiver 22 in the accommodating cavity 50 a.

Referring to fig. 1 and 2, in one embodiment, one of the columns 58 corresponds to the first light gathering structure 30 and the other column 58 corresponds to the second light gathering structure 40.

It can be appreciated that the requirement of the transmission of the optical signal on stability can be met while the transmitting end of the transmitter 21 or the receiving end of the receiver 22 is limited.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
