Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a cleaning device and a cleaning system. Background Technology

[0002] Cleaning equipment includes robotic vacuum cleaners, vacuum cleaners, and multi-functional cleaning base stations. Most cleaning equipment often uses cleaning components to clean dust, debris, hair, and other debris from surfaces to be cleaned.

[0003] In related technologies, cleaning devices are equipped with a drive assembly and a shielding component. The drive assembly moves the shielding component to adjust the size of the suction inlet of the cleaning assembly, thereby improving its cleaning effect. However, existing drive assemblies have relatively complex structures. Summary of the Invention

[0004] The main objective of this application is to provide a cleaning device and cleaning system to solve the problem of the complex structure of the drive assembly that drives the movement of the shielding component in the prior art.

[0005] According to one aspect of this application, a cleaning device is provided, comprising:

[0006] The body has an intake port at its bottom;

[0007] A shielding component is movably disposed on the body, the shielding component having a first position that reduces the opening size of the inlet and a second position that increases the opening size of the inlet;

[0008] The pump body component and the first drive component are both disposed on the machine body, and the first drive component is connected between the pump body component and the shielding component. The pump body component is used to transport pressure medium.

[0009] The first driving component is configured to drive the shielding component to the first position when the pump body component is turned on, and to drive the shielding component to the second position after the pump body component is turned off, or to drive the shielding component to the second position after the pump body component is turned off and then turned on again.

[0010] Furthermore, the first driving component is directly connected to the blocking component, so as to drive the blocking component to the first position when the pump body component is turned on, and to drive the blocking component to the second position after the pump body component is turned off; or,

[0011] A locking component is connected between the first driving component and the blocking component. When the pump body component is turned on, the locking component, driven by the first driving component, moves the blocking component to the first position and locks the blocking component in the first position. When the pump body component is turned off and then turned on again, the locking component, driven by the first driving component, unlocks the blocking component and moves the blocking component to the second position.

[0012] Furthermore, the locking component includes:

[0013] Base, the base being disposed on the fuselage;

[0014] A sliding component is disposed on the base and can reciprocate along a first direction or a second direction opposite to the first direction. The sliding component is connected to the blocking component and the first driving component respectively, and a first limiting part is provided on the sliding component.

[0015] A limiting fitting component, wherein the first end of the limiting fitting component is connected to the base, and the second end of the limiting fitting component opposite to the first end is rotatable around the first end and slides in contact with the sliding component;

[0016] When the pump body component is turned on, the first driving component drives the sliding component to move along the first direction to bring the blocking component to the first position. The second end contacts the first limiting part to lock the sliding component and lock the blocking component in the first position.

[0017] Furthermore, the base has a cavity, a connecting channel communicating with the cavity, and a groove; the second end has a bent section; and the sliding component includes:

[0018] A slider is movably disposed in the groove, and the slider is provided with a first guide channel and a protrusion structure, the protrusion structure having a first limiting part;

[0019] A push rod is disposed on the slider and extends along the first direction, and the push rod at least partially extends through the groove and is connected to the blocking component;

[0020] An abutment portion is disposed on the slider and at least partially located in the cavity; the first driving member at least partially passes through the connecting channel and is connected to the abutment portion.

[0021] When the first driving component drives the slider to move along the first direction through the abutment portion, the top rod moves with the slider and drives the blocking component to the first position, and the bent section slides from the first guide channel to the first limiting portion to lock the slider.

[0022] Furthermore, the slider is provided with a second limiting part and a second guide channel, the second guide channel is connected to the first guide channel, and an elastic reset member is sleeved on the top rod, the two opposite ends of the elastic reset member respectively abutting against the inner wall surface of the groove and the slider;

[0023] When the pump body component is closed and then reopened, the first driving component drives the slider to move along the first direction. The bent section separates from the first limiting part and moves to the second guide channel to unlock the slider. At the same time, the slider compresses the elastic reset member. After being unlocked, the slider moves along the second direction under the reset action of the elastic reset member to bring the blocking component to the second position, and the bent section moves along the second guide channel to the second limiting part.

[0024] Furthermore, one of the base and the sliding component is provided with a groove extending along the first direction, and the other is provided with a sliding protrusion adapted to the groove.

[0025] Furthermore, the machine body is provided with a second driving component and a moving component. The second driving component is connected between the pump body component and the moving component. The second driving component is configured to drive the moving component to lift the machine body along the height direction of the machine body after receiving the pressure medium delivered by the pump body component, and to drive the moving component to lower the machine body along the height direction of the machine body after the pump body component stops delivering the pressure medium.

[0026] Furthermore, the pump body component includes an air pump, the first driving component includes a first cylinder, the second driving component includes a second cylinder, the air pump is connected to the first cylinder through a first pipeline and to the second cylinder through a second pipeline; a first on / off component is provided on the first pipeline for controlling the on / off of the first pipeline, and a second on / off component is provided on the second pipeline for controlling the on / off of the second pipeline;

[0027] Specifically, when the second switching component controls the second pipeline to disconnect, the first switching component controls the first pipeline to connect; when the first switching component controls the first pipeline to disconnect, the second switching component controls the second pipeline to connect.

[0028] Further, the first on / off component includes a first solenoid valve or a one-way valve, the one-way valve having a first pressure threshold, wherein when the pressure output by the air pump to the first pipeline is greater than or equal to the first pressure threshold, the one-way valve controls the first pipeline to open; and / or,

[0029] The second on / off component includes a second solenoid valve.

[0030] Furthermore, a third pipeline is provided on the machine body, which is connected to the second pipeline and the outside. A pressure reducing valve is provided on the third pipeline, and the pressure reducing valve has a second pressure threshold, wherein:

[0031] After the moving component raises the machine body along its height, when the pressure output by the air pump is greater than or equal to the second pressure threshold, the pressure reducing valve controls the third pipeline to open; and / or,

[0032] The first on / off component includes a one-way valve, which has a first pressure threshold that is greater than a second pressure threshold.

[0033] On the other hand, this application also provides a cleaning system, which includes the cleaning equipment described above.

[0034] Since the first driving component in this application is connected between the pump body component and the shielding component, when it is necessary to change the position of the shielding component to adapt to different cleaning conditions, it is only necessary to control the opening and closing of the pump body component, without the need for an additional independent control switch or driving device. Specifically, when the cleaning operation needs to be switched to the concentrated suction mode, it is only necessary to turn on the pump body component to deliver the pressure medium. The pressure medium acts directly on the first driving component, and the power transmission does not need to go through other intermediate transmission components. The first driving component can quickly move the shielding component in the direction of reducing the size of the suction inlet until the shielding component reaches the first position. When it is necessary to switch to the normal cleaning mode, it is only necessary to turn off the pump body component to stop delivering the pressure medium. After the first driving component loses pressure support, it can automatically drive the shielding component to move in the opposite direction to the second position by means of the self-resetting characteristics of the first driving component, thereby increasing the size of the suction inlet opening. Alternatively, after the pump body component is turned off and then turned on again to deliver the pressure medium and let the pressure medium act directly on the first driving component, the first driving component will then drive the shielding component to move in the direction of increasing the size of the suction inlet to the second position. The entire transmission process can achieve power transmission through only the pump body component and the first drive component. The position switching of the shielding component can be completed without a complex transmission structure, which reduces the number of internal components and assembly difficulty, and also reduces the space occupied by the internal structure of the equipment, making it possible to design lightweight and miniaturized cleaning equipment.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0049] As mentioned in the background section, existing cleaning devices are equipped with a drive assembly and a shielding component. The drive assembly moves the shielding component to adjust the size of the suction inlet of the cleaning component, thereby improving its cleaning effect. However, existing drive assemblies have relatively complex structures. Therefore, the inventors of this application have designed a new cleaning device that at least solves the problem of the complex structure of the drive assembly that moves the shielding component in the prior art. The cleaning device of this application will be described in detail below with reference to the accompanying drawings.

[0050] See Figures 1 to 4 As shown, this application provides a cleaning device, which includes a body 10, a shielding component 20, a pump body component 30, and a first drive component 40.

[0051] Specifically, the bottom of the body 10 is provided with a suction port (not shown in the figure); the shielding member 20 is movably disposed on the body 10, and the shielding member 20 has a first position that reduces the size of the suction port opening and a second position that increases the size of the suction port opening; the pump body member 30 and the first drive member 40 are both disposed on the body 10, and the first drive member 40 is connected between the pump body member 30 and the shielding member 20, and the pump body member 30 is used to transport the pressure medium; wherein, the first drive member 40 is configured to drive the shielding member 20 to the first position when the pump body member 30 is turned on, and to drive the shielding member 20 to the second position after the pump body member 30 is turned off, or to drive the shielding member 20 to the second position after the pump body member 30 is turned off and then turned on again.

[0052] In this embodiment, the pump body component 30 can deliver a pressurized medium when it is turned on, and can stop delivering the pressurized medium when it is turned off. In actual use of the cleaning device, the device collects dirt into its own interior through the suction port to clean the surface to be cleaned. This embodiment allows the shielding component 20 to have two cleaning states by having a first position and a second position. When the shielding component 20 is in the second position, dirt on the surface to be cleaned can be sucked through the larger opening of the suction port; when the shielding component 20 is in the first position, dirt on the surface to be cleaned can be sucked through the smaller opening of the suction port. Because the opening size of the suction port when the shielding component 20 is in the first position is smaller than that when it is in the second position, the sealing of the suction port when the shielding component 20 is in the first position is higher than that when it is in the second position, thus providing a stronger suction effect on the surface to be cleaned.

[0053] Therefore, when cleaning hard surfaces such as floors and tiles, since dust, hair, and other dirt usually float on the surface, the shielding component 20 can be positioned in the second position, and the dirt on the surface can be cleaned through the suction port with a larger opening. When cleaning soft surfaces such as carpets, since dust, hair, and other dirt tend to embed deeply into the interior of the surface, the shielding component 20 can be positioned in the first position, and the surface can be deeply cleaned through the suction port with a smaller opening.

[0054] Meanwhile, since the first drive component 40 in this embodiment is connected between the pump body component 30 and the shielding component 20, when it is necessary to change the position of the shielding component 20 to adapt to different cleaning conditions, it is only necessary to control the opening and closing of the pump body component 30, without the need to set up an additional independent control switch or drive device. Specifically, when the cleaning operation needs to be switched to the concentrated suction mode, simply turn on the pump component 30 to deliver the pressure medium. The pressure medium acts directly on the first drive component 40 without passing through any other intermediate transmission components. The first drive component 40 can then quickly move the shielding component 20 in the direction of reducing the size of the suction inlet until the shielding component 20 reaches the first position. When it is necessary to switch to the regular cleaning mode, simply turn off the pump component 30 to stop delivering the pressure medium. The first drive component 40 loses pressure support and can then automatically drive the shielding component 20 to move in the opposite direction to the second position by means of the self-resetting characteristics of the first drive component 40, thereby increasing the size of the suction inlet. Alternatively, after the pump component 30 is turned off and then turned on again, it delivers the pressure medium and the pressure medium acts directly on the first drive component 40. The first drive component 40 then drives the shielding component 20 to move in the direction of increasing the size of the suction inlet to the second position. The entire transmission process can achieve power transmission through only the pump body component 30 and the first drive component 40. The position switching of the shielding component 20 can be completed without a complex transmission structure, which reduces the number of internal components and assembly difficulty, and also reduces the space occupied by the internal structure of the equipment, making it possible to design lightweight and miniaturized cleaning equipment.

[0055] Furthermore, such as Figures 3 to 4 As shown, in one embodiment of this application, the first driving component 40 is directly connected to the blocking component 20, so as to drive the blocking component 20 to a first position when the pump body component 30 is turned on, and to drive the blocking component 20 to a second position after the pump body component 30 is turned off. The first driving component 40 is directly connected to the blocking component 20, eliminating the intermediate transmission connectors that may exist in the prior art, making the power transmission path shorter and more direct.

[0056] Specifically, when the cleaning operation needs to be switched to a concentrated suction mode (such as cleaning soft surfaces like carpets), the pump component 30 is turned on. The pressure medium delivered by the pump component 30 acts directly on the first drive component 40. Since the first drive component 40 is directly connected to the shielding component 20, the driving force can be instantly transmitted to the shielding component 20, causing the shielding component 20 to move quickly to the first position. At this time, the suction inlet opening is reduced, the sealing is improved, and the negative pressure inside the device is more concentrated, which can deeply absorb dirt embedded in the surface to be cleaned. When the cleaning operation needs to be switched to a regular cleaning mode (such as cleaning hard surfaces like floors and tiles), the pump component 30 is turned off. The pump component 30 stops delivering the pressure medium. After the first drive component 40 loses pressure support, it can directly drive the shielding component 20 to move in the opposite direction to the second position by virtue of its own structural reset characteristics. The suction inlet opening is enlarged, which can quickly cover a larger cleaning area to collect dirt floating on the surface, and can also prevent large particles of debris from getting stuck in the suction inlet. Furthermore, this direct connection design allows the position switching of the shielding component 20 to be achieved simply by controlling the start and stop of the pump body component 30, without the need for manual adjustment or additional operation of a separate control switch. This simplifies the operation process, provides a faster response to different cleaning conditions, and reduces the probability of component failure by minimizing transmission components, thus extending the equipment's service life.

[0057] Furthermore, such as Figures 1 to 2 As shown, in another embodiment of this application, a locking component 50 is connected between the first driving component 40 and the blocking component 20. When the pump component 30 is turned on, the locking component 50, driven by the first driving component 40, moves the blocking component 20 to a first position and locks the blocking component 20 in the first position. When the pump component 30 is turned off and then turned on again, the locking component 50, driven by the first driving component 40, unlocks the blocking component 20 and moves the blocking component 20 to a second position. In this embodiment, the locking component 50 can form a stable limit after the blocking component 20 reaches the target position, avoiding the blocking component 20 from shifting due to factors such as device vibration and suction fluctuations during the cleaning process. This ensures that the size of the suction inlet opening remains accurate in different cleaning modes, and eliminates the need for an additional manual fixing structure, further simplifying operation and structural design.

[0058] Specifically, when the pump component 30 is switched to the concentrated suction mode, the pressure medium delivered by the pump component 30 drives the first drive component 40. The first drive component 40 simultaneously drives the locking component 50 and the shielding component 20 to move. When the shielding component 20 moves to the first position where the suction inlet opening is reduced, the locking component 50 triggers the locking mechanism to securely limit the shielding component 20 to the first position. At this time, the suction inlet sealing remains stable, and the device can always use a strong suction effect to deeply clean soft surfaces such as carpets. When the cleaning scene needs to be switched to the large opening mode, the pump component 30 is turned off first. After being turned on again, the first drive component 40 will first drive the locking component 50 to release the lock on the shielding component 20, and then continue to drive the shielding component 20 to move to the second position where the suction inlet opening is increased. This ensures that the shielding component 20 does not get stuck during the position switching process, and that it can stably adapt to the cleaning needs of hard surfaces such as floors and tiles after reaching the second position. This connection design with locking function not only solves the problem of easy displacement of the shielding component 20 in the traditional non-locking structure, ensuring the consistency of cleaning effect, but also allows the position switching and locking / unlocking actions to be completed in conjunction with the start / stop of the pump component 30 and the first drive component 40, without the need for additional operation of the locking control, thus simplifying the operation process.

[0059] Furthermore, such as Figures 5 to 8 As shown, the locking component 50 in this embodiment includes a base 51, a sliding component 52, and a limiting engagement component 54. The base 51 is disposed on the body 10; the sliding component 52 is disposed on the base 51 and can reciprocate along a first direction or a second direction opposite to the first direction. The sliding component 52 is connected to the blocking component 20 and the first driving component 40 respectively, and a first limiting portion 53 is provided on the sliding component 52; the first end 541 of the limiting engagement component 54 is connected to the base 51, and the second end 542 of the limiting engagement component 54, opposite to the first end 541, can rotate around the first end 541 and slide in contact with the sliding component 52; wherein, when the pump body component 30 is turned on, the first driving component 40 drives the sliding component 52 to move along the first direction to bring the blocking component 20 to a first position, and the second end 542 contacts the first limiting portion 53 to lock the sliding component 52, thereby locking the blocking component 20 in the first position. It should be noted that the "first direction" in this application refers to... Figure 5 The direction indicated by the middle arrow X; "second direction" refers to Figure 5 The direction indicated by the middle arrow Y.

[0060] Specifically, when the pump body component 30 is turned on, and the first drive component 40 drives the sliding component 52 to move along the first direction under the action of the pressure medium, the base 51 can prevent the sliding component 52 from shifting and shaking, ensuring the stability of the power transmission path. Since the sliding component 52 is connected to both the shielding component 20 and the first drive component 40, it can directly transmit the driving force to the shielding component 20, causing it to move until it reaches the first position with a reduced opening. At this time, the first limiting part 53 set by the sliding component 52 moves synchronously to the corresponding position, eliminating the need for an additional positioning structure. This allows the second end 542 of the limiting mating part 54 to rotate around the first end 541 connected to the base 51 and fit against the first limiting part 53 under the sliding contact action of the sliding component 52, forming a limiting lock on the sliding component 52. This, in turn, firmly limits the shielding component 20 to the first position, ensuring the airtightness of the suction port and a strong suction effect.

[0061] For example, the limiting fitting 54 in this embodiment includes a limiting rod.

[0062] Furthermore, such as Figures 5 to 8 As shown, in this embodiment, the base 51 has a cavity 511, a connecting channel 512 communicating with the cavity 511, and a groove 513. The second end 542 has a bent section 5421. The sliding component 52 includes a slider 521, a push rod 522, and an abutment portion 523. The slider 521 is movably disposed in the groove 513. The slider 521 is provided with a first guide channel 5211 and a protrusion structure 5212. The protrusion structure 5212 has a first limiting portion 53. The push rod 522 is disposed on the slider 521 and extends along a first direction. The push rod 522 at least partially protrudes from the groove 513 and is connected to the blocking component 20. The abutment portion 523 is disposed on the slider 521 and at least partially located in the cavity 511. The first driving component 40 at least partially passes through the connecting channel 512 and is connected to the abutment portion 523. In this embodiment, when the first driving component 40 drives the slider 521 to move along the first direction via the abutment part 523, the push rod 522 moves with the slider 521 and drives the blocking component 20 to the first position. The bent section 5421 slides from the first guide channel 5211 to the first limiting part 53 to lock the slider 521. In this embodiment, the groove 513 can directly plan a dedicated movement path for the sliding component 52, preventing the slider 521 from deviating from the direction when it moves, and ensuring accurate subsequent power transmission. The cavity 511 reserves space for the abutment part 523 to prevent the abutment part 523 from interfering with other components when it moves. The connecting channel 512 can also accurately align the connection position between the first driving component 40 and the abutment part 523, allowing the power of the first driving component 40 to be smoothly transmitted to the abutment part 523 without additional alignment adjustments.

[0063] Specifically, when the pump body component 30 is opened, the power of the first drive component 40 passes through the connecting channel 512 of the base 51 and acts on the abutment part 523 in the cavity 511. The abutment part 523 drives the slider 521 to move along the groove 513 in the first direction. The slider 521 simultaneously pushes the push rod 522, and the push rod 522 directly drives the shielding component 20 to move to the first position where the opening is reduced. During this process, the bent section 5421 slides along the first guide channel 5211 of the slider 521, and as the slider 521 moves, the bent section 5421 slides to the first limit part 53 to lock the slider 521, thereby keeping the shielding component 20 stably in the first position, ensuring the airtightness of the suction port to achieve strong suction. Throughout the process, no additional manual intervention is required. The precise structural adaptation ensures stable locking and efficient power transmission, and the absence of redundant components simplifies operation and maintenance, reducing the probability of failure.

[0064] Furthermore, such as Figures 6 to 7 As shown, in this embodiment, the slider 521 is provided with a second limiting part 5213 and a second guide channel 5214. The second guide channel 5214 is connected to the first guide channel 5211. An elastic reset member 60 is sleeved on the top rod 522. The two opposite ends of the elastic reset member 60 abut against the inner wall surface of the groove 513 and the slider 521, respectively. When the pump body component 30 is closed and then reopened, the first driving component 40 drives the slider 521 to move along the first direction. The bending section 5421 separates from the first limiting part 53 and moves to the second guide channel 5214 to unlock the slider 521. At the same time, the slider 521 compresses the elastic reset member 60. After unlocking, the slider 521 moves along the second direction under the reset action of the elastic reset member 60 to drive the blocking component 20 to the second position, so that the bending section 5421 moves along the second guide channel 5214 to the second limiting part 5213. In this embodiment, the newly added second limiting part 5213 and second guide channel 5214 on the slider 521, through the connection design between the second guide channel 5214 and the first guide channel 5211, provide a more complete sliding and unlocking path for the bent section 5421, avoiding jamming of the bent section 5421 during the unlocking process. The second limiting part 5213 can limit the bent section 5421 after the slider 521 is reset, ensuring that the next locking action can be accurately triggered.

[0065] Specifically, when the pump body component 30 is closed and then reopened, the first drive component 40 drives the slider 521 to move in the first direction. The slider 521 drives the first limiting part 53 of the protruding structure 5212 to move synchronously, causing the bent section 5421, which was originally stuck in the first limiting part 53, to disengage. Then, it slides into the second guide channel 5214 along the connected first guide channel 5211, completing the unlocking of the slider 521. During this process, when the slider 521 moves in the first direction, it squeezes the elastic reset member 60, causing the elastic reset member 60 to store reset potential energy. After unlocking is completed, the first drive component 40 stops applying force, the elastic reset member 60 releases its potential energy, and pushes the slider 521 to move in the opposite direction in the second direction. The slider 521 drives the blocking component 20 to move to the second position with an increased opening via the push rod 522. Meanwhile, the bent section 5421 slides along the second guide channel 5214 as the slider 521 moves in the opposite direction, eventually contacting the second limiting part 5213 on the slider 521. The second limiting part 5213 limits the bent section 5421, preventing the slider 521 from over-resetting and ensuring that when the pump body component 30 is turned on next time, the bent section 5421 can smoothly slide from the second limiting part 5213 into the first guide channel 5211 to achieve a new round of locking action. In other words, this embodiment ensures a smooth unlocking path through the interconnection design of the second guide channel 5214, and automatically resets the slider 521 with the help of the elastic reset component 60. The entire driving process not only reduces manual intervention but also eliminates the need for additional driving components. Furthermore, the limiting effect of the second limiting part 5213 ensures the stability of the component after reset, making the cleaning mode switching more efficient and further optimizing the overall reliability of the cleaning equipment.

[0066] For example, the elastic reset member 60 in this embodiment includes a spring, a metal sheet, or a torsion spring, etc. Any other variation of the concept of this application is within the protection scope of this application.

[0067] Furthermore, such as Figures 5 to 8 As shown, in this embodiment, one of the base 51 and the sliding member 52 is provided with a groove 514 extending along the first direction, and the other is provided with a sliding protrusion 5215 adapted to the groove 514. That is, the base 51 may have a groove 514 and the sliding member 52 may have a sliding protrusion 5215, or the base 51 may have a sliding protrusion 5215 and the sliding member 52 may have a groove 514. This application's... Figure 5The illustration shows the case where a groove 514 is provided on the base 51 and a sliding protrusion 5215 is provided on the sliding component 52. Specifically, in this embodiment, by using the sliding protrusion 5215 in conjunction with the groove 514, when the first driving component 40 drives the slider 521 to move, the sliding protrusion 5215 moves smoothly along the extension direction of the groove 514, providing additional guiding support for the slider 521. This prevents the top rod 522 from causing a positional deviation in the blocking component 20 due to the slider 521's offset, or misalignment between the bent section 5421 and the first guide channel 5211, the second guide channel 5214, the first limiting part 53, and the second limiting part 5213.

[0068] For example, in this embodiment, the groove 514 and the sliding protrusion 5215 can each be set to one, two, three, or more; this application does not make a specific limitation. Figure 5 The diagram shows the case where both the groove 514 and the sliding protrusion 5215 are set to two.

[0069] Furthermore, such as Figure 1 and Figure 3 As shown, in this embodiment, the body 10 is provided with a second drive component 70 and a moving component 80. The second drive component 70 is connected between the pump body component 30 and the moving component 80. The second drive component 70 is configured to drive the moving component 80 to lift the body 10 along the height direction after receiving the pressure medium delivered by the pump body component 30, and to drive the moving component 80 to lower the body 10 along the height direction after the pump body component 30 stops delivering the pressure medium. In this embodiment, the setting of the second drive component 70 and the moving component 80 continues the core logic of the equipment relying on the pump body component 30 to deliver the pressure medium for drive, without the need for an additional independent power source, further simplifying the overall drive system of the equipment. At the same time, by adjusting the height of the body 10, the cleaning equipment has obstacle-crossing capability, improving its flexibility of use.

[0070] Specifically, when the cleaning scenario requires raising the unit 10 (such as crossing a threshold or cleaning the edge of a thick carpet), the pump component 30 activates and delivers a pressurized medium to the second drive component 70. Under the pressure of the medium, the second drive component 70 generates driving force, causing the moving part 80 to move upwards along the height of the unit 10. During this movement, the moving part 80 supports the unit 10 and lifts it until its height matches the current scenario. When the unit 10 needs to be lowered, the pump component 30 stops delivering the pressurized medium, and the second drive component 70 loses pressure support, causing the moving part 80 to move downwards along the height of the unit 10. As the moving part 80 lowers, the unit 10 gradually approaches the surface to be cleaned, ensuring the suction inlet effectively contacts the surface for cleaning. The entire driving process requires no additional operation of a separate control switch, allowing height adjustment and cleaning mode switching to be synchronized.

[0071] Furthermore, such as Figure 1 and Figure 3 As shown, in this embodiment, the pump body component 30 includes an air pump 31, the first drive component 40 includes a first cylinder 41, and the second drive component 70 includes a second cylinder 71. The air pump 31 is connected to the first cylinder 41 through a first pipeline 11 and to the second cylinder 71 through a second pipeline 12. A first on / off component 14 is provided on the first pipeline 11 to control the on / off state of the first pipeline 11. A second on / off component 15 is provided on the second pipeline 12 to control the on / off state of the second pipeline 12. When the second on / off component 15 controls the second pipeline 12 to disconnect, the first on / off component 14 controls the first pipeline 11 to be open; when the first on / off component 14 controls the first pipeline 11 to disconnect, the second on / off component 15 controls the second pipeline 12 to be open. It is understood that in this embodiment, the first on / off component 14 and the second on / off component 15 are linked by a one-on-one linkage control logic to ensure that the first cylinder 41 and the second cylinder 71 do not receive gas delivered by the air pump 31 at the same time, so as to prevent the cleaning equipment from adjusting the position of the shielding component 20 and the height of the body 10 at the same time, thus avoiding structural damage caused by action conflict.

[0072] Specifically, when the cleaning operation requires adjusting the position of the shielding component 20 (e.g., switching to concentrated suction mode), the second on / off component 15 controls the second pipe 12 to disconnect, cutting off the gas supply from the air pump 31 to the second cylinder 71. Simultaneously, the first on / off component 14 controls the first pipe 11 to open, allowing the high-pressure gas output by the air pump 31 to enter the first cylinder 41 via the first pipe 11. Subsequently, the first cylinder 41, under gas pressure, drives the sliding component 52 to move, thereby causing the shielding component 20 to switch to the target position. When the height of the machine body 10 needs to be adjusted (e.g., to raise the machine body 10 to cross an obstacle), the first on / off component 14 controls the first pipeline 11 to disconnect, stopping the air supply to the first cylinder 41. Simultaneously, the second on / off component 15 controls the second pipeline 12 to open, allowing the high-pressure gas output from the air pump 31 to enter the second cylinder 71 via the second pipeline 12. Subsequently, the second cylinder 71 converts the gas pressure into lifting power, driving the moving part 80 to move and raise the machine body 10. When the pump body component 30 stops supplying air, it drives the moving part 80 to lower the machine body 10. In both operating conditions, the linkage control of the first on / off component 14 and the second on / off component 15 ensures that the power of the air pump 31 is always concentrated on supplying the currently operating drive component, avoiding action failure or jamming caused by power dispersion. This structural design not only allows each drive function of the equipment (obstruction adjustment, height adjustment) to be independently controlled and without interference, but also reduces manufacturing costs and maintenance difficulty through standardized air pump 31 and cylinder components.

[0073] Furthermore, such as Figure 1 and Figure 3As shown, the first on / off component 14 in this embodiment includes a first solenoid valve 141 or a one-way valve 142. The one-way valve 142 has a first pressure threshold. When the pressure output by the air pump 31 to the first pipeline 11 is greater than or equal to the first pressure threshold, the one-way valve 142 controls the first pipeline 11 to be open. It can be understood that the design of the first on / off component 14 in this embodiment, which includes the first solenoid valve 141 or the one-way valve 142, provides two adaptable solutions for pipeline on / off control. It can be flexibly selected according to the equipment cost budget and control accuracy requirements without reconstructing the overall pipeline system.

[0074] Specifically, when the first solenoid valve 141 is selected as the first on / off component 14, in the condition where the position of the blocking component 20 needs to be adjusted, the second on / off component 15 controls the second pipeline 12 to disconnect. At the same time, the control signal of the equipment control system is transmitted to the first solenoid valve 141. At this time, the first solenoid valve 141 actuates to open the first pipeline 11, so that the high-pressure gas output by the air pump 31 can enter the first cylinder 41 through the first pipeline 11, thereby driving the blocking component 20 to switch positions. When the one-way valve 142 is selected as the first on / off component 14, the same applies when adjusting the position of the blocking component 20. In the 0 position, the second on / off component 15 first cuts off the second pipeline 12. Then, the air pump 31 increases the output pressure. When the pressure is greater than or equal to the first pressure threshold of the one-way valve 142, the valve core of the one-way valve 142 opens under the action of gas pressure to make the first pipeline 11 open, so that the high-pressure gas can smoothly enter the first cylinder 41 to drive the blocking component 20 to move. If the output pressure of the air pump 31 is lower than the first pressure threshold, the valve core of the one-way valve 142 automatically resets, and the first pipeline 11 remains blocked, effectively avoiding gas leakage that would cause insufficient power in the first cylinder 41.

[0075] Furthermore, such as Figure 1 and Figure 3 As shown, the second on / off component 15 in this embodiment includes a second solenoid valve 151. Specifically, the second solenoid valve 151 can quickly switch the on / off state of the second pipeline 12 through an electrical control signal. It has a fast response speed and clear control logic, which can accurately match the cleaning conditions and prevent the second pipeline 12 from being accidentally opened when the machine body 10 does not need to be raised.

[0076] Furthermore, such as Figure 1As shown, in this embodiment, the body 10 is provided with a third pipeline 13, which is connected to the second pipeline 12 and the outside. A pressure reducing valve 16 is provided on the third pipeline 13, and the pressure reducing valve 16 has a second pressure threshold. Specifically, after the moving part 80 raises the body 10 along its height direction, when the pressure output by the air pump 31 is greater than or equal to the second pressure threshold, the pressure reducing valve 16 controls the third pipeline 13 to open. It can be understood that the third pipeline 13 in this embodiment provides a pressure release channel for the second pipeline 12 after the body 10 is raised, preventing the pressure in the second pipeline 12 from being continuously too high and causing overload of the second cylinder 71. At the same time, the pressure reducing valve 16 on the third pipeline 13 is set with a second pressure threshold, which can automatically control the pipeline opening based on pressure judgment, eliminating the need for additional monitoring or control components and simplifying the pressure protection logic.

[0077] Specifically, when the machine body 10 needs to be raised, the first on / off component 14 controls the first pipeline 11 to disconnect, and the second on / off component 15 controls the second pipeline 12 to open. Subsequently, the high-pressure gas output by the air pump 31 enters the second cylinder 71 through the second pipeline 12. The second cylinder 71 drives the moving part 80 to move upward along the height direction of the machine body 10 to gradually raise the machine body 10. As the machine body 10 is raised, if the air pump 31 continues to output high-pressure gas, causing the pressure in the second pipeline 12 to continuously increase, when the pressure is greater than or equal to the second pressure threshold of the pressure reducing valve 16, the valve core of the pressure reducing valve 16 opens under pressure, and the third pipeline 13 is opened accordingly. This allows excess high-pressure gas in the second pipeline 12 to be discharged to the outside through the third pipeline 13, so that the pressure in the second pipeline 12 drops back to a safe range. When the pressure in the second pipeline 12 drops below the second pressure threshold, the pressure reducing valve 16 automatically resets to close the third pipeline 13. The air pump 31 continues to supply air to the second cylinder 71 to maintain the current lifting height of the machine body 10, preventing the machine body 10 from falling due to insufficient pressure. In this embodiment, the cooperation between the third pipeline 13 and the pressure reducing valve 16 provides a reliable pressure protection mechanism for the lifting process of the machine body 10, preventing damage to components due to overload. At the same time, automatic control is achieved by relying on the second pressure threshold of the pressure reducing valve 16, without the need for additional electrical control signals or manual operation.

[0078] Furthermore, such as Figure 1As shown, the first on / off component 14 in this embodiment includes a one-way valve 142, which has a first pressure threshold greater than a second pressure threshold. Specifically, when the fuselage 10 needs to be raised, the second on / off component 15 controls the second pipeline 12 to open, and the air pump 31 starts to output pressure. When the pressure gradually rises to the second pressure threshold, the pressure reducing valve 16 responds and controls the third pipeline 13 to open as needed, thereby discharging excess pressure in the second pipeline 12 to the outside to maintain stable pressure in the second pipeline 12. At this time, because the pressure of the air pump 31 has not reached the first pressure threshold, the one-way valve 142 remains closed to prevent the first pipeline 11 from opening, thereby preventing the blocking component 20 from operating and ensuring that power is concentrated for adjusting the height of the fuselage 10. When the body 10 is raised to the position and the shielding component 20 needs to be adjusted, the air pump 31 continues to increase the output pressure until the pressure exceeds the second pressure threshold and reaches the first pressure threshold. The one-way valve 142 opens under high pressure to make the first pipeline 11 open, so that the high-pressure gas output by the air pump 31 can enter the first cylinder 41 through the first pipeline 11 to drive the sliding component 52 to switch the shielding component 20 to the target position.

[0079] like Figures 1 to 2 As shown, in the first embodiment of this application, the first driving component 40 is a first cylinder 41, and a locking component 50 is connected between the first cylinder 41 and the blocking component 20; the first on / off component 14 is a one-way valve 142, which is disposed on the first pipeline 11; the second driving component 70 is a second cylinder 71; the second on / off component 15 is a second solenoid valve 151, which is disposed on the second pipeline 12; and the pressure reducing valve 16 is disposed on the third pipeline 13.

[0080] Specifically, such as Figure 2 As shown, the control logic of the first embodiment in this application is as follows: First, the cleaning equipment is powered on and the pump body component 30 is opened. When the second solenoid valve 151 is opened and the one-way valve 142 is closed, the gas delivered by the pump body component 30 acts on the second cylinder 71 through the second pipeline 12. Under the action of air pressure, the second cylinder 71 generates driving force to drive the moving part 80 to lift the machine body 10 along the height direction of the machine body 10. Then, the pump body component 30 is closed, and the second cylinder 71 loses pressure support, so as to drive the moving part 80 to lower the machine body 10 along the height direction of the machine body 10; or, the pump body component 30 stops with a delay and continues to work. At this time, the pressure reducing valve 16 is opened to achieve pressure reduction until the pump body component 30 is closed.

[0081] When the second solenoid valve 151 is closed, the pump body component 30 increases the output pressure. When the pressure is greater than or equal to the first pressure threshold of the one-way valve 142, the valve core of the one-way valve 142 opens under the action of gas pressure to open the first pipeline 11, thereby facilitating the smooth entry of high-pressure gas into the first cylinder 41. The first cylinder 41 drives the locking component 50 to move, thereby moving the blocking component 20 to the first position. At this time, the locking component 50 locks the blocking component 20 in the first position. Subsequently, the pump body component 30 either delays stopping and continues to work or stops working directly. When the pump body component 30 delays stopping and continues to work until the locking component 50 is overloaded, the pump body component 30 stops working.

[0082] Next, when it is necessary to switch the blocking component 20 to the second position, the pump body component 30 restarts, so that the first cylinder 41 drives the locking component 50 to move under the pressure medium delivered by the pump body component 30. The locking component 50 first unlocks the blocking component 20 and then drives the blocking component 20 to switch to the second position.

[0083] like Figures 3 to 4 As shown, in the second embodiment of this application, the first driving component 40 is a first cylinder 41, which is directly connected to the blocking component 20; the first on / off component 14 is a first solenoid valve 141, which is disposed on the first pipeline 11 to control the on / off state of the first pipeline 11; the second on / off component 15 is a second solenoid valve 151, which is disposed on the second pipeline 12 to control the on / off state of the second pipeline 12.

[0084] Specifically, such as Figure 4 As shown, the control logic of the second embodiment in this application is as follows: First, the cleaning equipment is powered on and the pump body component 30 is opened. When the second solenoid valve 151 is opened, the gas delivered by the pump body component 30 acts on the second cylinder 71 through the second pipeline 12. Under the action of air pressure, the second cylinder 71 generates driving force to drive the moving part 80 to lift the machine body 10 along the height direction of the machine body 10. Then, the pump body component 30 is closed, the second solenoid valve 151 is closed, and the second cylinder 71 drives the moving part 80 to lower the machine body 10 along the height direction of the machine body 10.

[0085] When the first solenoid valve 141 is opened, the pressure medium delivered by the pump body component 30 directly acts on the first cylinder 41, and the first cylinder 41 drives the shielding component 20 to move to the first position. When the deep cleaning operation is completed, the pump body component 30 is closed, the first solenoid valve 141 is closed, and the first cylinder 41 drives the shielding component 20 to move to the second position.

[0086] On the other hand, this application also provides a cleaning system that includes the aforementioned cleaning equipment. Therefore, this cleaning system encompasses all the technical effects of the aforementioned cleaning equipment. Since the technical effects of the cleaning equipment have already been described in detail above, they will not be repeated here.

[0087] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
