Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0042] Currently, cleaning equipment such as robotic vacuum cleaners typically have functions like vacuuming and mopping to clean floors. However, these cleaning devices suffer from poor energy efficiency when cleaning floors. For example, when using the vacuuming function, these devices usually employ a fan to drive airflow and create suction, drawing dust, hair, and other debris into a dustbin. Simultaneously, the airflow from the fan is expelled into the environment through an air duct. This wastes airflow energy, resulting in poor energy efficiency.

[0043] To address the aforementioned technical problems, this disclosure provides a cleaning device with at least one air-using component on its housing and a gas delivery device at the air outlet of a fan. The gas delivery device delivers the airflow discharged from the air outlet of the fan to the at least one air-using component, thereby enabling the function of the at least one air-using component. This allows for the reuse of the wind energy generated by the fan, effectively improving the energy-saving effect of the cleaning device and enhancing the user experience.

[0044] An exemplary embodiment of this disclosure provides a cleaning device, such as Figure 1 As shown, the cleaning device 1 includes a housing 11, a fan 13, and a gas delivery device 12. At least one air-using component is disposed on the housing 11. Exemplarily, only one air-using component may be disposed on the housing 11, or multiple air-using components may be disposed. In this embodiment, an air-using component refers to a component that can utilize airflow to achieve its own function. For example, components such as the drive wheel 141 and the mop tray 173 can achieve the obstacle-crossing function of the cleaning device 1 by floating up and down. Therefore, when the above-mentioned components can utilize airflow to achieve their own up and down floating, they can constitute the air-using component in this embodiment.

[0045] The fan 13 is housed within the casing 11. The fan 13 drives airflow to generate suction on the ground, thereby adsorbing impurities and cleaning the surface to be cleaned. The surface to be cleaned can be, for example, the floor, a tabletop, etc.

[0046] A gas delivery device 12 is disposed at the air outlet of the blower 13. The gas delivery device 12 delivers the airflow discharged from the air outlet of the blower 13 to at least one gas-consuming component. Exemplarily, the gas delivery device 12 can deliver the airflow discharged from the air outlet of the blower 13 to only one gas-consuming component, or to multiple gas-consuming components, or to each gas-consuming component, so that each gas-consuming component can use the airflow discharged from the air outlet of the blower 13 to perform its function.

[0047] This design enables the reuse of wind energy generated by the fan 13, effectively improving the energy-saving effect of the cleaning equipment 1 and thus enhancing the user experience.

[0048] Combination Figure 2 , Figure 3 and Figure 4 In one embodiment, at least one air-using component includes a first air-using component, which includes a travel module and a first adjustment unit 111. The travel module is disposed in the housing, and it is understood that the travel module refers to a component that can realize the walking function of the cleaning device 1. In this embodiment, the travel module includes a drive wheel mechanism or a caster wheel assembly 16.

[0049] Combination Figure 1 and Figure 2 Both the drive wheel mechanism and the caster wheel assembly 16 are located on the housing 11, with the caster wheel assembly 16 positioned upstream of the drive wheel mechanism in the forward direction of the cleaning device 1. The cleaning device 1 can move via the drive wheel mechanism and the caster wheel assembly 16. Furthermore, the caster wheel assembly 16 further enhances the stability of the cleaning device 1's movement and acts as a guide, improving the smoothness of the cleaning device 1's movement and thus effectively increasing its cleaning efficiency.

[0050] The first adjustment part 111 is disposed on the traveling module. That is, when the traveling module is a drive wheel mechanism, the first adjustment part 111 is disposed on the drive wheel mechanism; when the traveling module is a caster wheel assembly 16, the first adjustment part 111 is disposed on the caster wheel assembly 16. When the traveling module is both a drive wheel mechanism and a caster wheel assembly 16, both the drive wheel mechanism and the caster wheel assembly 16 are provided with the first adjustment part 111.

[0051] The first adjustment unit 111 is used to adjust the distance between the housing 11 and the surface to be cleaned by the airflow delivered by the gas delivery device 12. Exemplarily, when the cleaning device 1 encounters an obstacle, the first adjustment unit 111 drives the drive wheel mechanism or the caster wheel assembly 16 to move via airflow, thereby increasing the distance between the housing 11 and the surface to be cleaned, allowing the housing 11 to cross the obstacle and continue normal operation. After the housing 11 crosses the obstacle, it returns to its original position. Exemplarily, the first adjustment unit 111 may be, for example, an airbag or other component that can use air pressure to drive the movement of functional parts.

[0052] In this embodiment, the movement of the drive wheel mechanism or the universal wheel assembly 16 is driven by the first adjustment unit 111, resulting in a simple structure that facilitates the lightweight design of the cleaning equipment 1. Simultaneously, it enables the reuse of wind energy generated by the fan 13, effectively improving the energy-saving performance of the cleaning equipment 1 and thus enhancing the user experience.

[0053] Combination Figure 3and Figure 4 In one embodiment, the drive wheel mechanism includes a drive wheel assembly 14. The drive wheel assembly 14 is rotatably connected to the housing 11 via a shaft, for example, and has a first obstacle-crossing position and a first initial position. When the drive wheel assembly 14 is in the first obstacle-crossing position, the distance between the housing 11 and the surface to be cleaned is greater than the distance between the housing 11 and the surface to be cleaned when the drive wheel assembly 14 is in the first initial position. This enables the cleaning device 1 to have obstacle-crossing functionality, thereby improving the user experience. By adopting the above configuration, the drive wheel mechanism has a simple structure and is easy to manufacture.

[0054] Combination Figure 3 In one embodiment, the drive wheel assembly 14 includes a mounting portion and a drive portion and a drive wheel 141 disposed on the mounting portion. The mounting portion is rotatably connected to the housing 11, for example, via a rotating shaft. The drive portion includes, for example, a drive motor fixed to the mounting portion, or a drive motor and a gear assembly fixed to the mounting portion, with the drive motor and gear assembly drivingly connected. The drive portion can drive the rotation of the drive wheel 141. This design facilitates the installation and fixing of the drive portion and the drive wheel 141, and also facilitates the obstacle-crossing function of the cleaning device 1 via the drive wheel 141.

[0055] Combination Figure 1 and Figure 5 In one embodiment, two drive wheel mechanisms are provided, located on opposite sides of the travel direction of the cleaning device 1. When two drive wheel mechanisms are provided, two first adjustment parts 111 are also provided. The two first adjustment parts 111 respectively drive the two drive wheel mechanisms to adjust the distance between the housing 11 and the surface to be cleaned. This improves the stability of the cleaning device 1 during travel.

[0056] Combination Figure 3 and Figure 4 In one embodiment, the first adjustment unit 111 has a first inflation state and a first deflation state. Airflow is delivered to the first adjustment unit 111 through the air supply pipe 123 to put the first adjustment unit 111 into the first inflation state. When the cleaning device 1 encounters an obstacle, the first adjustment unit 111 is put into the first inflation state. When the first adjustment unit 111 is in the first inflation state, the drive wheel assembly 14 can reach the first obstacle-crossing position, increasing the distance between the housing 11 and the surface to be cleaned, thereby enabling the cleaning device 1 to cross the obstacle.

[0057] After the housing 11 crosses the obstacle, the first adjustment unit 111 begins to release air. Under the influence of gravity, the housing 11 gradually falls towards the surface to be cleaned until the first adjustment unit 111 is in the first venting state, at which point the housing 11 returns to its original position. Simultaneously, the drive wheel assembly 14 reaches its first initial position. During this process, the airflow discharged from the first adjustment unit 111 can be transported to other air-using components or discharged through the airflow delivery device 12. This facilitates the first adjustment unit 111's control over the drive wheel assembly 14, thereby adjusting the distance between the housing 11 and the surface to be cleaned.

[0058] Combination Figure 3 and Figure 4 In one embodiment, the drive wheel mechanism further includes a push rod assembly 15, which is disposed on the housing 11, and a first adjustment part 111 is disposed on the push rod assembly 15. During the inflation process of the first adjustment part 111, the push rod assembly 15 pushes the drive wheel assembly 14 to move until the first adjustment part 111 is in a first inflation state, at which point the drive wheel assembly 14 reaches a first obstacle-crossing position. By pushing the drive wheel assembly 14 under the action of the first adjustment part 111 through the push rod assembly 15, the distance between the housing 11 and the surface to be cleaned is adjusted. This design facilitates the driving of the drive wheel assembly 14 and makes the structure of the drive wheel mechanism more compact.

[0059] Combination Figure 2 , Figure 3 and Figure 4 In one embodiment, the push rod assembly 15 includes a sleeve 151 and a push rod 152. The sleeve 151 is fixed to the housing 11 and includes a sealed end and an open end. The push rod 152 is disposed inside the sleeve 151, and the pushing end of the push rod 152 extends out of the sleeve 151 through the open end to abut against the drive wheel assembly 14. A first adjusting part 111 is disposed between the push rod 152 and the sealed end. The airflow delivery device 12 can pass through the sealed end of the sleeve 151 through a through hole and communicate with the first adjusting part 111 to deliver airflow to the first adjusting part 111. When the first adjusting part 111 is being inflated, the pushing end of the push rod 152 gradually extends out of the sleeve 151 to drive the drive wheel assembly 14 to rotate and raise the height of the housing 11. During the venting process of the first adjustment section 111, the housing 11 gradually falls, the drive wheel assembly 14 rotates in the opposite direction, and pushes the push rod 152 to gradually extend into the sleeve 151 until the housing 11 returns to its original position. This configuration makes the push rod assembly 15 simple in structure and easy to manufacture.

[0060] Combination Figure 6 and Figure 7In one embodiment, the caster wheel assembly 16 includes a fixing part 161 and a caster wheel 162. The first end of the fixing part 161 is slidably connected to the housing 11, and the fixing part 161 has a second initial position and a second obstacle-crossing position. When the fixing part 161 is in the second obstacle-crossing position, the distance between the housing 11 and the surface to be cleaned is greater than the distance between the housing 11 and the surface to be cleaned when the fixing part 161 is in the second initial position. This allows the caster wheel assembly 16 to float up and down, facilitating the obstacle-crossing function of the cleaning device 1. The above-described configuration makes the structure of the caster wheel assembly 16 simple and easy to manufacture.

[0061] Combination Figure 6 and Figure 7 In one embodiment, a first adjusting part 111 is disposed between the fixing part 161 and the housing 11. The first adjusting part 111 has a second inflated state and a second deflated state. An airflow is delivered to the first adjusting part 111 via a gas delivery device 12, so that the first adjusting part 111 is in the second inflated state. During the inflation process of the first adjusting part 111, the fixing part 161 moves from a second initial position towards a second obstacle-crossing position, and the height of the housing 11 gradually increases until the first adjusting part 111 is in the second inflated state and the fixing part 161 reaches the second obstacle-crossing position.

[0062] After the housing 11 crosses the obstacle, the first adjustment section 111 begins to release air. Under the influence of gravity, the housing 11 gradually falls towards the surface to be cleaned. The fixing section 161 moves from the second obstacle-crossing position to the second initial position until the first adjustment section 111 is in the second air-release state, the housing 11 returns to its original position, and the fixing section 161 reaches the second initial position. During this process, the airflow discharged from the first adjustment section 111 can be transported to other air-using components or discharged through the gas delivery device 12. This design facilitates the first adjustment section 111 to control the caster wheel assembly 16, thereby adjusting the distance between the housing 11 and the surface to be cleaned.

[0063] Combination Figure 7 In one embodiment, the housing 11 has a groove 113 corresponding to the fixing part 161, and the first end of the fixing part 161 is slidably connected in the groove 113. This allows for the installation of the fixing part 161. This arrangement simplifies the structure of the cleaning device 1, making it easier to manufacture and assemble.

[0064] In one embodiment, a first mating part is provided on the sidewall of the groove 113, and a second mating part is provided on the fixing part 161. The first mating part and the second mating part cooperate to restrict the movement of the fixing part 161 between the second obstacle-crossing position and the second initial position. Exemplarily, the first mating part can be a slide rail, and the second mating part can be a slider. The slider slides along the slide rail to restrict the movement of the fixing part 161 between the second obstacle-crossing position and the second initial position. Alternatively, the first mating part can be a groove, and the second mating part can be a locking structure that slides along the groove. The locking structure slides along the groove to restrict the movement of the fixing part 161 between the second obstacle-crossing position and the second initial position. This design effectively prevents the fixing part 161 from shifting or falling off during movement, thereby further improving the reliability of the cleaning device 1.

[0065] In one embodiment, one of the first mating part and the second mating part is a first sliding groove, and the other of the first mating part and the second mating part is a first limiting protrusion. Exemplarily, the first sliding groove can be provided on the sidewall of the groove 113 and the first limiting protrusion can be provided on the fixing part 161, or the first limiting protrusion can be provided on the sidewall of the groove 113 and the first sliding groove can be provided on the fixing part 161. This simplifies the structure of the first mating part and the second mating part, facilitating manufacturing. The extending direction of the first sliding groove is parallel to the moving direction of the fixing part 161, thus effectively improving the smoothness of the sliding of the fixing part 161.

[0066] Combination Figure 1 , Figure 8 and Figure 9 In one embodiment, at least one air-using component further includes a second air-using component, which includes a cloth tray assembly 17 and a second adjustment part 112. The cloth tray assembly 17 is disposed on the housing 11 and can wipe the surface to be cleaned to achieve cleaning. The second adjustment part 112 is disposed on the cloth tray assembly 17 to adjust the distance between the cloth tray assembly 17 and the surface to be cleaned by the airflow delivered by the gas delivery device 12.

[0067] This prevents the mop tray assembly 17 from wetting surfaces such as carpets that cannot tolerate moisture, and also prevents the carpet from obstructing the movement of the mop tray assembly 17. For example, when the cleaning device 1 moves from the floor onto the carpet, the distance between the mop tray assembly 17 and the floor is first increased via the second adjustment part 112 to prevent the mop tray assembly 17 from wetting the carpet and to prevent the carpet from obstructing its movement. After the cleaning device 1 has passed the carpet, the distance between the mop tray assembly 17 and the floor is decreased via the second adjustment part 112, so that the mop tray assembly 17 is in contact with the floor for continued cleaning.

[0068] The cleaning effect on the surface to be cleaned can also be improved by adjusting the floating degree of the mop tray assembly 17. For example, the floating degree of the mop tray assembly 17 can be adjusted according to the degree of dirt on the surface to be cleaned, thereby adjusting the pressure exerted by the mop tray assembly 17 on the surface to be cleaned. For example, when the surface to be cleaned is dirty, the pressure exerted by the mop tray assembly 17 on the surface to be cleaned is increased to improve the cleaning effect of the mop tray assembly 17 on the surface to be cleaned. When the surface to be cleaned is relatively clean, reducing the pressure exerted by the mop tray assembly 17 on the surface to be cleaned can also ensure the cleaning effect of the mop tray assembly 17 on the surface to be cleaned. When it is necessary to increase the pressure exerted by the mop tray assembly 17 on the surface to be cleaned, airflow is delivered to the second adjustment unit 112 through the gas delivery device 12. When it is necessary to reduce the pressure exerted by the mop tray assembly 17 on the surface to be cleaned, the gas in the second adjustment unit 112 is delivered to other gas-using components or discharged through the airflow delivery device 12. With this configuration, the cleaning effect of the cleaning equipment 1 can be effectively improved, thereby further enhancing the user experience.

[0069] Combination Figure 9 In one embodiment, the cloth tray assembly 17 includes a rotating shaft assembly and a driving device. A cloth tray 173 is mounted on the rotating shaft assembly, and the driving device is mounted on the housing 11 and connected to the rotating shaft assembly. The driving device drives the rotating shaft assembly to rotate the cloth tray 173. This effectively improves the cleaning effect on the surface to be cleaned. A second adjustment part 112 is mounted on the rotating shaft assembly. The second adjustment part 112 is used to adjust the distance between the cloth tray 173 and the surface to be cleaned by the airflow delivered by the gas delivery device 12. This arrangement facilitates the installation of the second adjustment part 112 while avoiding interference between the second adjustment part 112 and the driving device, thereby further improving the reliability of the cleaning equipment 1.

[0070] Combination Figure 9 In one embodiment, the rotating shaft assembly includes a first rotating shaft 171 and a second rotating shaft 172, with the outer peripheral surface of the first rotating shaft 171 being driven to a driving device. Exemplarily, a toothed structure is provided on the outer peripheral surface of the first rotating shaft 171. The driving device includes a drive motor and a gear assembly, the gear assembly meshing with the toothed structure on the first rotating shaft 171, and the drive motor being driven to the gear assembly, thus achieving a driving connection between the outer peripheral surface of the first rotating shaft 171 and the driving device.

[0071] The first rotating shaft 171 has a cavity with one open end. The first end of the second rotating shaft 172 extends into the cavity from the open end of the first rotating shaft 171 and is slidably connected to the first rotating shaft 171. The wiping tray 173 is disposed at the second end of the second rotating shaft 172. The second rotating shaft 172 has a third obstacle-crossing position and a third initial limit position. When the second rotating shaft 172 is in the third obstacle-crossing position, the distance between the wiping tray 173 and the surface to be cleaned is greater than the distance between the wiping tray 173 and the surface to be cleaned when the second rotating shaft 172 is in the third initial position. This allows the wiping tray 173 to float up and down, thereby further improving the cleaning effect of the cleaning device 1. The above-described configuration simplifies the structure of the rotating shaft assembly and facilitates manufacturing.

[0072] Combination Figure 9 In one embodiment, the second adjustment section 112 is disposed between the first end of the second rotating shaft 172 and the sealing end of the first rotating shaft 171. The second adjustment section 112 has a third inflation state and a third deflation state. Airflow is delivered to the second adjustment section 112 via the gas delivery device 12 to place the second adjustment section 112 in the third inflation state. During the inflation process, the second rotating shaft 172 moves from the third obstacle-crossing position to the third initial position, gradually decreasing the distance between the wiping disc 173 and the surface to be cleaned, or gradually increasing the pressure exerted by the wiping disc 173 on the surface to be cleaned, until the second adjustment section 112 is in the third inflation state and the second rotating shaft 172 reaches the third initial position.

[0073] During the venting process of the second adjustment unit 112, the second rotating shaft 172 moves from the third initial position to the third obstacle-crossing position to gradually increase the distance between the wiping tray 173 and the surface to be cleaned or gradually decrease the pressure exerted by the wiping tray 173 on the surface to be cleaned, until the second adjustment unit 112 is in the third venting state and the second rotating shaft reaches the third obstacle-crossing position. During this process, the airflow discharged from the second adjustment unit 112 can be transported to other air-using components or discharged through the gas delivery device 12. In this way, the second adjustment unit 112 can control the wiping tray assembly 17, thereby adjusting the distance between the wiping tray 173 and the surface to be cleaned.

[0074] In one embodiment, a third mating part is provided on the inner sidewall of the first rotating shaft 171, and a fourth mating part is provided on the outer surface of the second rotating shaft 172. The third mating part and the fourth mating part cooperate to restrict the movement of the second rotating shaft 172 between the third obstacle-crossing position and the third initial position. For example, the third mating part can be a slide rail, and the fourth mating part can be a slider. The slider slides along the slide rail to restrict the movement of the second rotating shaft 172 between the third obstacle-crossing position and the third initial position. Alternatively, the third mating part can be a groove, and the fourth mating part can be a locking structure that slides along the groove. The locking structure slides along the groove to restrict the movement of the second rotating shaft 172 between the third obstacle-crossing position and the third initial position. This design effectively prevents the second rotating shaft 172 from shifting or falling off during movement, thereby further improving the reliability of the cleaning device 1.

[0075] In one embodiment, one of the third and fourth mating parts is a second groove, and the other is a second limiting protrusion. Exemplarily, the second groove can be provided on the inner wall of the first rotating shaft 171, and the second limiting protrusion can be provided on the outer surface of the second rotating shaft 172; alternatively, the second limiting protrusion can be provided on the inner wall of the first rotating shaft 171, and the second groove can be provided on the outer surface of the second rotating shaft 172. This simplifies the structure of the third and fourth mating parts and facilitates manufacturing. The extending direction of the second groove is parallel to the moving direction of the second rotating shaft 172, thus effectively improving the smoothness of the sliding of the second rotating shaft 172.

[0076] Combination Figure 1 and Figure 5 In one embodiment, two cloth tray assemblies 17 are provided, and correspondingly, two second adjustment units 112 are also provided. The two second adjustment units 112 respectively drive the movement of the two cloth tray assemblies 17 to adjust the distance between the cloth tray assembly 17 and the surface to be cleaned or to adjust the pressure of the cloth tray assembly 17 on the surface to be cleaned. In this way, the cleaning effect and obstacle-crossing ability of the cleaning device 1 on the surface to be cleaned can be further improved.

[0077] In one embodiment, both the first adjustment part 111 and the second adjustment part 112 are airbags, that is, combined with Figure 1 and Figure 4 The first adjustment part 111 used to drive the drive wheel assembly 14 is a first airbag. Figure 1 and Figure 7 The first adjustment part 111 used to drive the universal wheel assembly 16 is a second airbag. Figure 9 The second adjustment part 112 used to drive the cloth tray 173 is a third airbag.

[0078] The gas delivery device 12 delivers the airflow discharged from the outlet of the blower 13 to each airbag. Each airbag adjusts the distance between its housing and the surface to be cleaned, or adjusts the distance between the corresponding functional component and the surface to be cleaned, through airflow adjustment. This arrangement simplifies the structure of the adjustment unit, making it easy to manufacture and assemble.

[0079] Combination Figure 1 In one embodiment, the gas delivery device 12 includes a diversion component 121, an inlet pipe 122, and at least one delivery pipe 123. The diversion component 121 includes an inlet end and at least one delivery end. One end of the inlet pipe 122 is connected to an air outlet, and the other end of the inlet pipe 122 is connected to the inlet end. The number of delivery ends of the diversion component 121 corresponds to the number of gas-using components. For example, when there is only one gas-using component, the diversion component 121 has one delivery end and one delivery pipe 123; when there are multiple gas-using components, such as five gas-using components, the diversion component 121 has five delivery ends and five delivery pipes 123. The first end of each delivery pipe 123 is connected to each delivery end, and the second end of each delivery pipe 123 is connected to each gas-using component. The air intake duct 122 collects air from the outlet of the fan 13 and directs it to the distribution component 121, which then distributes the airflow to each air-using component. This arrangement simplifies the structure of the gas delivery device 12, making it easier to process and assemble, while reducing the space occupied inside the housing 11, thus facilitating the miniaturization of the cleaning equipment 1.

[0080] Combination Figure 1 In one embodiment, the diversion component 121 further includes an exhaust end, and the gas delivery device 12 further includes an exhaust pipe 124. One end of the exhaust pipe 124 is connected to the exhaust end, and the other end of the exhaust pipe 124 is used to discharge the airflow entering the exhaust pipe 124 to the outside of the housing 11. For example, when none of the gas-using components need to use airflow, the diversion component 121 discharges all the airflow entering from the intake pipe 122 to the outside of the housing 11 through the exhaust pipe 124; or, when the gas-using components need to reduce or discharge gas, the diversion component 121 can also discharge the airflow exiting from the supply pipe 123 to the outside of the housing 11 through the exhaust pipe 124. This design can effectively regulate the airflow, avoid airflow stagnation affecting the normal use of the cleaning equipment 1, thereby effectively improving the reliability of the cleaning equipment 1.

[0081] In one embodiment, the flow divider 121 includes a multi-way pneumatic valve, which has an inlet end and at least one outlet end. One end of the inlet pipe 122 is connected to the outlet, and the other end of the inlet pipe 122 is connected to the inlet end. The first ends of each outlet pipe 123 are respectively connected to the outlet end. By using a multi-way pneumatic valve as the flow divider 121, it is easier to control the flow divider 121.

[0082] In one embodiment, the cleaning device 1 further includes a control unit electrically connected to the diversion component 121. The control unit is configured to control the diversion component 121 to reverse the airflow according to indication information. Exemplarily, the indication information may be, for example, an obstacle crossing indication, a reset indication, a pressurization indication, a depressurization indication, etc.

[0083] When no instruction is received, the control unit controls the diversion component 121 to discharge all the airflow entering from the intake pipe 122 through the exhaust pipe 124.

[0084] When an obstacle crossing instruction is received, the control unit controls the diversion component 121 to divert the airflow entering through the intake pipe 122 to the first airbag and the second airbag through the air delivery pipe 123, and / or controls the diversion component 121 to discharge the airflow discharged from the third airbag through the exhaust pipe 124.

[0085] When a reset instruction is received, the control unit controls the diversion component 121 to discharge the airflow from the first airbag and the second airbag through the exhaust pipe 124, and / or controls the diversion component 121 to divert the airflow entering the intake pipe 122 to the third airbag through the air delivery pipe 123.

[0086] When a pressurization instruction is received, the control unit controls the diversion component 121 to deliver the airflow entering through the intake pipe 122 to the third airbag through the delivery pipe 123.

[0087] When a decompression instruction is received, the control unit controls the diversion component 121 to discharge the airflow from the third airbag through the exhaust pipe 124.

[0088] This design effectively improves the convenience and accuracy of controlling the diversion component 121, and enables independent control of each gas-consuming component according to specific usage scenarios, thereby further enhancing the energy-saving effect of the cleaning equipment 1 and the user experience.
