[0034] As shown in Figures 1 and 2, a blower device 4 disclosed in this application includes:

[0035] Air blowing channel 1 includes a channel housing 101 with a curvature;

[0036] The blower module 2 is embedded in the channel housing 101;

[0037] The blower head 3 is fitted at the end of the blower channel 1. When the blower module 2 is activated, it generates air in the blower channel 1, and the blower head 3 blows air outward.

[0038] [Corrected according to detailed rule 91 28.09.2025] Wherein, the blowing channel 1 can be formed by two symmetrical and identical channel shells 101. The outer surface of each channel shell 101 is provided with a connection position, and the connection positions are symmetrical. Connecting parts, such as bolts, can be inserted through the connection positions. In this way, the channel shells 101 can be fixedly connected to form the blowing channel 1. In addition, the channel shell 101 is made into a shell with a curvature, which has a sound-absorbing function. Specifically, when the airflow passes through the curved blowing channel 1, the tangential acceleration of the curve causes the airflow to rotate, forming a rotating gas layer, avoiding the direct impact of the airflow, thereby achieving the sound-absorbing effect. It also has the ability to ensure that the wind force is more concentrated and stronger during the blowing process, specifically by changing the direction and intensity of the wind force. This allows for a more uniform and effective distribution of airflow within the channel. The blowing module 2 can be a device that generates flowing air, constructed from a centrifugal motor. The centrifugal motor operates based on centrifugal force, using the centrifugal force generated during rotation to drive objects or produce effects. The blowing module 2 can be installed at the opening in the middle of the channel housing 101, and it can be embedded inside the channel housing 101. When the blowing module 2 is activated, it generates corresponding flowing air. The blowing head 3 can be located at the end of the blowing channel 1, which is equivalent to the air outlet of the blowing channel 1. The flowing air at the air outlet can have its blowing direction changed by the blowing head 3. Thus, the blowing head 3 can blow flowing air to a specific area, moving the material in that specific area to the corresponding target area.

[0039] In this embodiment, the blower 4 blows various small objects such as leaves, grass clippings, and snow in the courtyard area toward the target area. As long as it does not affect the area where the user walks, the cleanliness of the courtyard area can be guaranteed, the aesthetic effect of the courtyard environment can be improved, and the user's walking will not be directly affected, thus improving the user's experience.

[0040] As shown in Figure 4, in some embodiments, the air blowing channel 1 includes two identical channel housings 101, which are symmetrically installed to form the air blowing channel 1.

[0041] [Correction based on Rule 91 28.09.2025] The number of channel housings 101 can be two. The two channel housings 101 can be stably installed in a symmetrical manner to form a blowing channel 1 that allows air to flow.

[0042] As shown in Figures 2, 3 and 4, in some embodiments, the blower module 2 includes a blower motor 201, an impeller component 202 and a ventilation component 203. The blower motor 201 is driven by the impeller component 202. After the ventilation component 203 is installed in the channel housing 101, the ventilation component 203 is located above the impeller component 202.

[0043] The blower module 2 passes through the opening of the channel housing 101, the ventilation component 205 is installed in the opening of the channel housing 101, and the blower motor 201 is located at the tail of the blower module 2. Thus, its installation position is located away from the opening of the ventilation component 203. In addition, the impeller component 202 is disposed between the ventilation component 203 and the blower motor 201. The blower motor 201 and the impeller component 202 are connected by a drive. When the blower motor 201 is started, the impeller component 202 rotates and generates corresponding airflow.

[0044] As shown in Figures 4 and 5, in some embodiments, the blower motor 201 includes a drive shaft 204, which is inserted into the connection hole 2021 of the impeller component 202.

[0045] The impeller component 202 has a hub, and the connecting hole 2021 on the hub is adapted to the drive shaft 204. Thus, the rotation of the drive shaft 204 can drive the entire impeller component 202 to rotate.

[0046] As shown in Figures 4 and 5, in some embodiments, the impeller component 202 has a ventilation opening 2022, the ventilation opening 2022 and the ventilation component 203 are symmetrically arranged at intervals, and a plurality of blades 2023 are arranged at intervals from the connection hole 2021 to the outer periphery of the impeller component 202.

[0047] The ventilation openings 2022 and ventilation components 203 in the impeller component 202 are symmetrically arranged at intervals, that is, outside air can enter the impeller component 202 through the ventilation components 203 and ventilation openings 2022. Multiple blades 2023 are arranged at intervals from the connecting hole 2021 to the outer periphery of the impeller component 202. The rotation of multiple blades 2023 can increase the intensity of the airflow in the blowing channel 1. In addition, the structure of the impeller component 202 can be a hollow turntable with ventilation openings 2022 inside. The ventilation openings 2022 are opened at the upper end of the structure and the connecting hole 2021 is opened at the lower end.

[0048] As shown in Figure 2, in some embodiments, a fixed post 2031 is provided at the center of the ventilation component 203, and a plurality of ventilation fins 2032 are provided at intervals from the fixed post 2031 to the outer periphery of the ventilation component 203.

[0049] The ventilation component 203 has a fixed column 2031 at its center, and multiple ventilation fins 2032 are arranged at intervals from the fixed column 2031 to the outer periphery of the ventilation component 203. The interval between each ventilation fin 2032 can be the same or different. The shape of the ventilation fin 2032 can be set to a structure with a certain curvature to reduce the resistance to air entry.

[0050] As shown in Figures 2 and 4, in some embodiments, the blower head 3 is provided with a connecting air outlet 301 and a blower outlet 302 connected to one air outlet end of the connecting air outlet 301, and the other air outlet end of the connecting air outlet 301 is connected to the end of the channel housing 101.

[0051] The air outlet 302 is fixedly connected to the air outlet 301 at one end, and the end of the channel housing 101 is fixedly connected to the air outlet 301 at one end. In this way, the airflow can flow throughout the air duct and blow towards the designated area.

[0052] In some embodiments, the air outlet 302 includes an upper air outlet (not shown) and a lower air outlet (not shown), the upper air outlet (not shown) passing through the lower air outlet (not shown), and the upper air outlet (not shown) and the lower air outlet (not shown) sharing the same air outlet end.

[0053] The upper air outlet (not shown) directs the airflow upwards from the ground, while the lower air outlet (not shown) directs the airflow downwards from the ground. The two air outlets are stacked one on top of the other and use the same air outlet. This means that after the airflow passes through the air outlet, it can be divided into two flow directions. Thus, the air outlet 302 has different airflow directions, which can increase the intensity of blowing the material and prevent insufficient airflow due to wind obstruction.

[0054] As shown in Figures 1, 2, 3 and 4, in some embodiments, the air outlet 302 is elongated.

[0055] The air outlet 302 is elongated, meaning it has both long and short sides. The arrangement of the long and short sides allows the air outlet 302 to have a larger airflow range.

[0056] As shown in Figures 6 and 7, to address the problem that most current cleaning machines are operated manually with low automation and lack the ability to automatically identify small objects and obstacles, the blowing device 4 disclosed in this application embodiment further includes:

[0057] Mounting bracket 5 includes upper mounting bracket 501 and lower mounting bracket 502;

[0058] [Correction based on Rule 91 28.09.2025] Identification module 6 includes a first mounting component 601 and an identification component 602 mounted on the first mounting component 601. The first mounting component 601 and the upper mounting bracket 501 form an installation space for mounting the air blowing channel 1.

[0059] The collision module 7 protrudes from the lower mounting bracket 502.

[0060] Among them, the mounting bracket 5 is the basic structure of the entire blower 4. The mounting bracket 5 may include an upper mounting bracket 501 and a lower mounting bracket 502. The relative installation positions of the upper mounting bracket 501 and the lower mounting bracket 502 are different. The relative installation position of the upper mounting bracket 501 can be understood as the upper position of the blower 4 in the working state, and the relative installation position of the lower mounting bracket 502 can be understood as the lower position of the blower 4 in the working state. The two mounting brackets can be fixedly connected by bolts, rivets, screws or snap-fit ​​parts.

[0061] [Corrected according to Rule 91, 28.09.2025] The blower module 2 may include a blower channel 1 and a blower head 3. The blower channel 1 is installed in the installation space formed by the first mounting component 601 and the upper mounting bracket 501 (the blower channel 1 is installed in the installation space after the first mounting component 601 and the upper mounting bracket 501 are connected). The blower channel 1 may be formed by two symmetrical and identical channel housings 101. The outer surface of each channel housing 101 is provided with a connection position, and the connection positions are symmetrical. Connectors such as bolts can be inserted through the connection positions. In this way, the channel housings 101 can be fixedly connected to form the blower channel 1. In addition, the channel housing 101 is made into a curved shape. The curved shell has a noise reduction function. Specifically, when the airflow passes through the curved air blowing channel 1, the tangential acceleration of the bend causes the airflow to rotate, forming a rotating gas layer, which avoids the direct impact of the airflow and thus achieves the noise reduction effect. It also ensures that the wind force is more concentrated and stronger during the blowing process. Specifically, it changes the direction and intensity of the wind force, so that the wind force is more evenly and effectively distributed in the channel. The blower head 3 can be set at the end of the air blowing channel 1, which is equivalent to the air outlet of the air blowing channel 1. The airflow at the air outlet can change the blowing direction through the blower head 3. In this way, the blower head 3 can blow airflow to a specific area outside, moving the material in the specific area to the corresponding target area.

[0062] [Corrected according to Rule 91 28.09.2025] The identification module 6 may include a first mounting component 601 and an identification component 602. The first mounting component 601 may be a housing structure for mounting the identification component 602. An opening (first opening) adapted to the identification component 602 is formed on the first mounting component 601. The identification camera or identification probe in the identification component 602 is installed in the opening (first opening). Other electronic components in the identification component 602 are housed in the internal space formed by the first mounting component 601. The identification component 602 may be at least one of a camera or an ultrasonic radar. In addition, the number of openings (first openings) formed by the identification module 6 is not specifically limited. Multiple identification components 602 may be set according to the requirements of identification accuracy. For example, two openings (first openings) are formed on the first mounting component 601 for placing a binocular camera. The binocular camera can identify the distance between the blower 4 and the obstacle.

[0063] The collision module 7 can be a structure consisting of a collision sensor (not shown) and a collision strip 701. The collision strip 701 can be made of metal and can be hollow inside. A protective sleeve with protective or cushioning material can be provided at the position where the collision strip 701 contacts the external obstacle. The protective sleeve can be made of a material with a certain elastic deformation. After the protective sleeve is provided, fixing plugs for fixing the protective sleeve to the collision strip 701 and preventing water ingress can be provided on both sides of the collision strip 701. In this way, the collision strip 701 can play a protective function when colliding with the obstacle. The collision sensor (not shown) can be located inside the collision strip 701, which is also the position where the collision strip 701 is most likely to come into contact with the external obstacle. It can be triggered when contacting the obstacle (Figure 701). The detection circuit in the collision sensor (not shown) can include a pressure sensor and a photoelectric sensor. The sensitive element in the pressure sensor is in contact with the outer shell of the collision strip 701. After the collision strip 701402 comes into contact with an external obstacle, the collision strip 701 will cause the sensitive element to deform or displace, and the detection circuit in the pressure sensor can sense the collision signal. The photoelectric sensor is equipped with a transmitter and a receiver. The passage between the transmitter and the receiver can be kept open. The transmitter is in contact with the outer shell of the collision strip 701. After the collision strip 701 comes into contact with an external obstacle, the collision strip 701 will cause the transmitter to displace, thereby closing the original passage, and the detection circuit in the photoelectric sensor can sense the collision signal.

[0064] In this embodiment, the blowing module 2 in the blowing device 4 blows various small objects such as leaves, grass clippings, and snow in the courtyard area toward the target area, ensuring that it does not affect the user's walking area. This maintains the cleanliness of the courtyard area, improves the aesthetics of the courtyard environment, and does not directly affect the user's walking, thus enhancing the user experience. In addition, the recognition module 6 in the blowing device 4 can identify the various small objects mentioned above or the distance between them and obstacles. The collision module 7 in the blowing device 4 can determine the collision situation between the blowing device 4 and the obstacle. Thus, the automation level can be improved by automatically recognizing various situations.

[0065] [Correction 28.09.2025 according to Rule 91] As shown in FIG7, in one embodiment, a connecting member 8 is connected between the first mounting member 601 and the second mounting member 901 and the upper mounting bracket 501.

[0066] [Corrected according to Rule 91 28.09.2025] Wherein, the connecting component 8 can serve as a connecting mechanism between the first mounting component 601 and the upper mounting frame 501. By providing a fixing structure inside the connecting component 8 that can be connected to the first mounting component 601, the first mounting component 601 can be fixed to the upper mounting frame 501 by the fixing structure after the connecting component 8 is placed on the upper mounting frame 501. The connecting component 8 can also serve as a connecting mechanism between the second mounting component 901 and the upper mounting frame 501. By providing a fixing structure inside the connecting component 8 that can be connected to the second mounting component 901, the second mounting component 901 can be fixed to the upper mounting frame 501 by the fixing structure after the connecting component 8 is placed on the upper mounting frame 501.

[0067] [Correction 28.09.2025 according to Rule 91] As shown in FIG6, in one embodiment, the blower device 4 further includes a lighting module 9, the lighting module 9 including a second mounting component 901 and a lighting component 902 mounted on the second mounting component 901, the second mounting component 901, the first mounting component 601 and the upper mounting bracket 501 forming an installation space for mounting the blower channel 1.

[0068] [Correction based on Rule 91, 28.09.2025] The lighting module 9 may include a second mounting component 901 and a lighting component 902. The second mounting component 901 may be a housing structure for mounting the lighting component 902. An opening (second opening) adapted to the lighting component 902 is formed on the second mounting component 901. The lamp plate of the lighting component 902 can be mounted in this opening (second opening). Other electronic components in the lighting component 902 are housed within the internal space formed by the second mounting component 901. The housing on the second mounting component 901 can be docked with the upper mounting bracket 501 to form a mounting bracket. The installation space for the air blowing channel 1 is provided, and the housing on the first mounting component 601 can also be connected with the upper mounting bracket 501 to form the installation space for the air blowing channel 1. The air blowing channel 1 is then installed in the installation space formed by the three components. The lighting component 902 can be a long strip of LED light panel. The long strip design can increase the lighting coverage of the air blowing device 4, which is beneficial to the recognition accuracy in low ambient light conditions. In addition, there is no specific limit to the number of lighting modules 9. Multiple lighting modules 9 can be set according to the lighting range requirements. For example, lighting modules 9 can be set on the left and right sides of the air blowing device 4.

[0069] [Correction 28.09.2025 according to Rule 91] As shown in FIG6, in one embodiment, the first mounting component 601 has a first opening adapted to the identification component 602, and the second mounting component 901 has a second opening adapted to the lighting component 902.

[0070] [Correction based on Rule 91 28.09.2025] The first opening can fix the first mounting component 601 to the blower 4, improving the recognition accuracy, and the second opening can fix the second mounting component 901 to the blower 4, improving the lighting effect.

[0071] As shown in Figures 6 and 7, in one embodiment, the collision module 7 includes a collision sensor (not shown) and a collision strip 701. The collision strip 701 is internally provided with a collision sensor (not shown) for identifying collisions, and the collision strip 701 protrudes relative to the lower mounting bracket 502.

[0072] The collision strip 701 protrudes outward from the mounting bracket. Specifically, a support component protruding outward can be provided on the lower mounting bracket 502. The collision strip 701 is installed on the support component. In this way, when the blower 4 collides, the collision strip 701 first collides with the obstacle, and the collision signal is identified by the collision sensor (not shown) installed inside the collision strip 701.

[0073] As shown in Figures 1 and 4, in one embodiment, the air blowing channel 1 includes two identical channel housings 101. The two channel housings 101 are symmetrically installed to form the air blowing channel 1.

[0074] [Correction based on Rule 91 28.09.2025] The number of channel housings 101 can be two. The two channel housings 101 can be stably installed in a symmetrical manner to form a blowing channel 1 that allows air to flow.

Thus, its installation position is located away from the opening of the ventilation component 203. In addition, the impeller component 202 is disposed between the ventilation component 203 and the blower motor 201. The blower motor 201 and the impeller component 202 are connected by a drive. When the blower motor 201 is started, the impeller component 202 rotates and generates corresponding airflow.

[0078] The impeller component 202 is equipped with a hub, and the connecting hole 2021 of the hub is adapted to the drive shaft 204. Thus, the rotation of the drive shaft 204 can drive the entire impeller component 202 to rotate. The ventilation port 2022 and the ventilation component 203 in the impeller component 202 are symmetrically arranged at intervals, that is, the outside air can enter the impeller component 202 through the ventilation component 203 and the ventilation port 2022. Multiple blades 2023 are arranged at intervals from the connecting hole 2021 to the outer periphery of the impeller component 202. The rotation of multiple blades 2023 can increase the intensity of the airflow in the blowing channel 1. In addition, the structure of the impeller component 202 can be a hollow turntable with blades 2023 set inside. The upper end of this structure has a ventilation port 2022 and the lower end has a connecting hole 2021.

[0082] The air outlet 302 is fixedly connected to the air outlet 301 at one end, and the end of the channel housing 101 is fixedly connected to the air outlet 301 at one end. In this way, the airflow can flow throughout the air duct and blow towards the designated area.

[0083] As shown in Figures 8 and 9, the cleaning device involves the connection between a power plug and a power socket. However, the power socket in existing cleaning devices is not fixed. To address the issue that the working vibration of the cleaning device can easily cause the power plug to detach from the power socket, and the fact that the power cord is not properly stored, making it easy for the cord to be stretched, further increasing the risk of the power plug detaching from the power socket, the blower device 4 disclosed in this application embodiment further includes a fixing module connected to the mounting bracket 502; the fixing module includes:

[0084] Mounting component 10 includes a fixing plate 1001 and a mounting box 1002. The fixing plate 1001 is provided on one side of the mounting box 1002, and an installation opening for fixing the wire socket 12 is provided on the other side of the mounting box 1002. The fixing plate 1001 is fixedly connected to the external structure.

[0085] The bundle 11 is located on the same horizontal level as the mounting position and is used to store and fix the wires connected to the wire socket 12.

[0086] [Corrected according to Rule 91, September 28, 2025] The surface of one side of the fixing plate 1001 can be connected to an external structure, which can be the mounting bracket 5 on the blower 4 or other locations on the robot where the wire socket 12 can be installed. The surface of the fixing plate 1001 can be provided with multiple fixing positions (not shown in the figure) for connection to the external structure, such as multiple screw holes for threaded connection. The shape of the mounting box 1002 is adapted to the wire socket 12, that is, a mounting position for fixing the wire socket 12 is provided on one side of the mounting box 1002. The mounting box 1002 and the external structure only form a single point through which the wire socket 12 protrudes. The opening (the wire socket can be directly connected to the wire plug) and the surrounding fixing positions (not shown) on the mounting box 1002 can also be distributed together to fix the mounting member 10 on the surface of the external structure together with the fixing positions (not shown) of the fixing plate 1001; the bundle member 11 can be provided with an arched annular part 1101, the annular part 1101 is hollow in the middle, the annular part 1101 can be fixedly connected to the mounting plate 1102 of the bundle member 11 through the fixing positions (not shown), the setting of the annular part 1101 and the mounting position are on the same installation horizontal line, after the wire plug is connected to the wire socket of the wire socket 12, the wire can be stored and fixed in the hollow space of the annular part 1101;

[0087] In this embodiment, the electrical socket 12 is fixed by the mounting box 1002 in the mounting component 10, and the entire mounting box 1002 is fixed to the external structure by the fixing plate 1001 in the mounting component 10. The wires leading out of the electrical socket 12 in the mounting box 1002 are stored by the bundle member 11. In this way, the electrical socket 12 will not easily fall off in the working state, and the wires connected to the electrical socket 12 are stored, reducing the risk of the wires falling off the electrical socket 12.

[0088] As shown in Figure 9, in one embodiment, both the fixing plate 1001 and the mounting box 1002 are provided with fixing positions (not shown), which are used for fixed connection with external structures.

[0089] The multiple fixing positions (not shown in the figure) can stably fix the mounting box 1002 in the external structure.

[0090] As shown in FIG9, in one embodiment, the cluster member 11 includes an annular portion 1101 and a mounting plate 1102. The annular portion 1101 is disposed on the surface side of the mounting plate 1102, and the side of the mounting plate 1102 is fixedly connected to an external structure.

[0091] [Correction 28.09.2025 according to Rule 91] The annular portion 1101 can also be fixed to the surface of the mounting plate 1102 by means of the mounting position, such as fixing positions (not shown) provided on the left and right sides of the annular portion 1101. The mounting plate 1102 can be composed of a mounting surface 11021 and a fixing surface 11022 that are connected.

[0092] [Correction 28.09.2025 based on Rule 91] As shown in FIG8, in one embodiment, the mounting plate 1102 includes a mounting surface 11021 and a fixing surface 11022. An annular portion 1101 is provided on the mounting surface 11021, and a fixing position (not shown) is provided on the fixing surface 11022 for fixed connection with an external structure.

[0093] [Corrected according to Rule 91 28.09.2025] The mounting surface 11021 and the fixing surface 11022 can form a connection angle. Each surface has a structure. An annular part 1101 is provided on the mounting surface 11021, and a fixing position (not shown) for connection with an external structure is provided on the fixing surface 11022.

[0094] [Correction 28.09.2025 according to Rule 91] As shown in Figures 10 and 11, in one embodiment, the lower mounting frame 502 is provided with an obstacle-crossing component 14 near the bottom of the ground. The obstacle-crossing component 14 includes a guide surface 1401 and a reinforced bottom surface 1402, and the guide surface 1401 is fixedly connected to the reinforced bottom surface 1402.

[0095] [Correction based on Rule 91, 28.09.2025] In the blower device 14, both the guide surface 1401 and the reinforced bottom surface 1402 can protrude relative to the edge of the lower mounting frame 1302. The blower device 14 is designed to allow the robot with the blower device 4 installed to easily navigate and overcome obstacles, reducing the risk of frequent shaking and the risk of the power cord plug coming off the power socket. The guide surface 1401 can enhance obstacle-crossing ability. The design of the guide surface 1401 allows the robot to pass through ground obstacles (such as small stones, protrusions, etc.) more smoothly, reducing damage or jamming caused by collisions, thereby improving the stability and reliability of the entire device or system. The reinforced bottom surface 1402 can protect the bottom of the blower device 4. The reinforced bottom surface 1402 not only increases the structural strength of the lower mounting frame 502, but also provides additional protection when in contact with the ground.

[0096] As shown in Figures 10 and 11, in one embodiment, the guide surface 1401 is inclined relative to the reinforced bottom surface 1402, and the guide surface 1401 and the reinforced bottom surface 1402 are connected by a reinforcing surface 1403.

[0097] [Correction based on Rule 91, 28.09.2025] The guide surface 1401 is inclined relative to the reinforced bottom surface 1402, which can significantly reduce the risk of the blower 4 getting stuck or damaged due to obstacles. The reinforcing surface 1403 can be set inside the lower mounting bracket 502. The presence of the reinforcing surface 1403 significantly enhances the connection strength between the guide surface 1401 and the reinforced bottom surface 1402, making the overall structure more stable and reliable, and improving the service life and safety of the blower 4.

[0098] This application also discloses a robot (not shown in the figures), comprising:

[0099] Blowering device 4;

[0100] The moving vehicle body (not shown) is connected to the blower 4.

[0101] [Correction based on Rule 91, September 28, 2025] The mobile body is a self-moving body. The robot formed by using this body and the blower 4 can automatically blow air in the target area to move the corresponding material to the target area. At the same time, during the operation, the identification module 16 can identify the small objects and obstacles that need to be cleaned, and the collision module 7 can determine the collision with the obstacles. Then, it can make corresponding planning and processing autonomously, such as controlling the robot to move to the corresponding target area and clean the small objects, or controlling the robot to avoid obstacles in advance, or controlling the robot to retreat after colliding with obstacles.
