Description

Technical Field

[0001] The present disclosure relates to a surface cleaning device. Background Art

[0002] Surface cleaning devices are suitable for cleaning hard floor surfaces such as tiles and hardwood, as well as soft floor surfaces such as carpets and cushions. In the design of surface cleaning devices, in order to achieve the twisting of the body relative to the cleaning head, a rotation mechanism is usually provided at the connection between the body and the cleaning head. This rotation mechanism allows the body to rotate around the cleaning head, thereby providing operational flexibility, such as adjusting the body angle during cleaning to adapt to different cleaning scenarios.

[0003] When the surface cleaning device is in an upright state, the body of the device is easily rotated around the cleaning head due to gravity, causing the body to tilt, affecting the balance of the machine, and a mechanism to fix the body is required. Traditional solutions have high requirements for user operation. When the body is reset, the locking structure is not aligned, which will cause the body to tilt excessively, posing a safety risk of the machine tipping over. Summary of the invention

[0004] The present disclosure provides a surface cleaning device, comprising: an upright body for housing a vacuum motor for generating suction; a recovery tank located upstream of the vacuum motor; a cleaning head having an airflow path, the cleaning head being connectable to the upright body so that when the cleaning head is connected to the upright body, foreign matter on the surface to be cleaned is guided along the airflow path and collected in a recovery box by suction generated by the vacuum motor; A connecting portion is arranged between the cleaning head and the upright body, and the connecting portion connects the cleaning head and the upright body; The connecting portion is rotatable relative to the upright body about a first pivot axis; The telescopic structure is arranged on the connecting part and is configured to couple and decouple the connecting part and the upright body; when the connecting part and the upright body are in the mutually coupled state, the upright body can deflect relative to the connecting part and be locked to the connecting part by the telescopic structure.

[0005] According to an example of the present disclosure, when the connecting portion and the upright body are in a mutually coupled state, the upright body can be locked by the connecting portion within a deflection angle range relative to the connecting portion, and the deflection angle range is greater than or equal to -15° and less than or equal to 15°.

[0008] According to an example of the present disclosure, the limiting groove structure includes a main limiting groove and a secondary limiting groove arranged adjacent to at least one side of the limiting groove, and in a coupled state, the main limiting groove and the secondary limiting groove can selectively accommodate the free end of the telescopic structure.

[0009] According to an example of the present disclosure, when the main limiting groove accommodates the free end of the telescopic structure, the upright body and the connecting portion are aligned; when the secondary limiting groove accommodates the free end of the telescopic structure, the upright body is deflected relative to the connecting portion.

[0010] According to an example of the present disclosure, the bottom of the secondary limiting groove has a guide slope toward the bottom of the primary limiting groove, and is configured to guide the free end of the telescopic structure to move in a direction away from the primary limiting groove.

[0012] According to an example of the present disclosure, the trigger is located on the cleaning head.

[0013] According to an example of the present disclosure, the connection portion includes: a shell; a bracket coupled to the housing and configured to receive the retractable structure; and The elastic reset member is used to connect the telescopic structure to the bracket in a resettable manner.

[0023] The present disclosure is further described in detail below in conjunction with the accompanying drawings and examples. It is understood that the specific examples described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0024] It should be noted that, in the absence of conflict, the examples and features in the examples in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with examples.

[0025] Unless otherwise specified, the exemplary examples / examples shown will be understood as exemplary features that provide various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various examples / examples can be combined, separated, interchanged and / or rearranged in addition without departing from the technical concept of the present disclosure.

[0026] In the prior art, this design of the surface cleaning device brings a significant technical problem when the body is in an upright state: due to the effect of gravity, the body is prone to uncontrolled rotation around the rotation axis of the cleaning head, causing the body to tilt. This tilt not only affects the balance of the machine, making it difficult to stand stably, but also may cause the risk of tipping over, especially when stored or suspended. Excessive rotation and tilting of the body will reduce the user experience, such as the need to frequently adjust the position of the body to keep it upright, and may also cause physical damage to the equipment, such as hitting the ground and causing parts to loosen or break. Therefore, a mechanism is needed to fix the body, limit its rotation in an upright state, and ensure the balance and safety of the machine.

[0027] The limiting effect of the prior art is highly dependent on the precise alignment of the retractable structure and the hole. If the body fails to properly align with the hole during the resetting process (for example, due to improper user operation or displacement of the cleaning head), the free end of the retractable structure cannot smoothly enter the hole, resulting in failure of the limiting function. At this time, the body may still rotate around the cleaning head, causing excessive tilt or even tipping over. This alignment requirement increases the difficulty of user operation, especially when quickly adjusting the body state, the user needs to ensure that the relative position of the body and the cleaning head are completely consistent, otherwise the limiting mechanism will not be effective. This reliance on precise alignment makes the prior art solution a potential safety hazard in actual use, especially in a home environment, where children or pets may accidentally touch the body, further amplifying the risk of tipping over.

[0028] The present disclosure provides a surface cleaning device, whose upright position limiting mechanism is intended to enhance stability in an upright state. The device includes an upright body accommodating a vacuum motor and a recovery tank, a cleaning head defining an airflow path (which can be connected to the upright body to collect debris), and a connecting portion pivotally connecting the cleaning head and the upright body. The connecting portion rotates around a first pivot relative to the upright body and rotates around a substantially vertical second pivot relative to the cleaning head, thereby achieving multi-directional adjustment. The retractable structure on the connecting portion can selectively couple or decouple the connecting portion and the upright body, and limit the rotation around the first pivot within a range of -15° to 15° in the coupled state. That is, in the coupled state, the upright body and the connecting portion can be locked within a range of -15° to 15°. The upright body has a limiting slot structure with a main slot and adjacent secondary slots, which are circumferentially distributed within a range of 15°, for receiving the free end of the retractable structure to ensure stability even in the case of misalignment. A trigger component on the cleaning head activates the coupling in the upright position and releases the coupling during operation, and an elastic return component helps the retractable structure return.

[0029] Compared with the prior art, the present invention improves the upright stability and safety of the surface cleaning device. Unlike the traditional design that relies on precise alignment to limit rotation, the present invention limits the locking of the upright body in the upright state within the range of -15° to 15° through the main limiting groove and the secondary limiting groove, which can reduce the risk of tipping even if it is not locked in alignment with the connecting part. A safe upright state is achieved, the convenience of use is improved, and the overall stability, safety and ease of use are better than the existing solutions.

[0030] Other aspects of the present disclosure will be partially described in the following description, and partially will be obvious from the description, or can be learned through the practice of the present disclosure. An embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0035] In the following detailed description, terms such as “front side”, “rear side”, “left side”, and “right side” may be defined by the drawings, but the shapes and positions of components are not limited by these terms.

[0036] Figure 1 A schematic structural diagram of the surface cleaning device 1 is provided, showing its main components: a handle 30 , an upright body 20 , a connecting portion 100 and a cleaning head 10 . Figure 1 Provides a basis for understanding the implementation of the present disclosure. Figure 1In a preferred example, the surface cleaning device includes a handle 30 detachably mounted to an upright body 20, and the body is pivotally connected to the cleaning head 10 via a connecting portion 100. The handle 30 is provided with a user interaction button for controlling the start and stop of the device, the liquid delivery rate, the suction power, and optional functions such as the activation of a voice interaction system and volume adjustment, thereby improving the user experience.

[0037] The cleaning head 10 can absorb foreign matter (such as hair) on the surface to be cleaned by the suction force of air. The cleaning head 10 can move on the surface to be cleaned while absorbing foreign matter such as dust on the surface.

[0038] An airflow path may be formed inside the cleaning head 10. The airflow path formed inside the cleaning head 10 may be communicated with the upright body 20 through the connection portion 100. External air and foreign matter introduced through the cleaning head 10 may move into the upright body 20 through the connection portion 100.

[0039] like Figure 2 As shown, the connecting portion 100 may be rotatably connected to the cleaning head 10. As the connecting portion 100 rotates around the cleaning head 10, the cleaning head 10 may rotate around the upright body 20 connected to the connecting portion 100. Therefore, the degree of freedom of operation of the surface cleaning device 1 may be improved.

[0040] The upright body 20 may form a part of the appearance of the surface cleaning device 1. One end of the upright body 20 may be mounted to the cleaning head 10. Specifically, one end of the upright body 20 may be pivotally mounted to the connecting portion 100. The handle 30 may be removably connected to the other end of the upright body 20. With respect to the cleaning head 10, the handle 30 may be operated to move the upright body 20 within a first angle range that limits the relative free pivoting of the connecting portion 100 and the upright body 20 and a second angle range that keeps the connecting portion 100 and the upright body 20 from relative free pivoting.

[0041] According to some examples, the upright body 20 may be connected to the cleaning head 10. The connecting portion 100 may be coupled to the upright body 20 and the cleaning head 10, respectively, to connect the upright body 20 to the cleaning head 10. For example, one end of the upright body 20 may be coupled to the connecting portion 100.

[0042] In some examples, such as Figures 1 to 3 The connecting portion 100 may be coupled to the lower end of the upright body 20 to limit the pivotal freedom of the upright body 20 relative to the connecting portion 100. The connecting portion 100 may be coupled to the upright body 20 via a limiting device. Figure 3 As shown, in the connection portion 100, the telescopic structure 111 provided in the limiting device can be engaged with the limiting groove 112 provided at the ring member 201 at the port at the lower end of the upright body.

[0043] The limiting device is configured to fix or release the coupling state between the cleaning head 10 and the upright body 20. For example, the limiting device can couple the cleaning head 10 to the upright body 20 to limit the relative pivoting between the cleaning head 10 and the upright body 20; or uncouple the upright body 20 from the cleaning head 10 so that the cleaning head 10 and the upright body 20 can independently pivot while maintaining the connection state. The user can change the relative position of the cleaning head 10 and the upright body 20 in the front-to-back direction (the direction in which the surface cleaning device runs) by operating the handle 30 to couple and uncouple the upright body 20 and the cleaning head 10 through the limiting device. The limiting device can be arranged on the side opposite to the connecting portion 100 and the upright body 20. The user only needs to operate the handle 30 to change the relative angle between the upright body 20 and the cleaning head 10 to achieve the pivot locking between the connecting portion and the upright body 20.

[0044] In some examples, such as Figure 3 and Figure 4 As shown, the upright body 20 may include a limiting groove 112. The limiting groove 112 may be formed at the end of the upright body 20. In some examples, the limiting groove 112 may be recessed inward from the ring member 201 at the end of the upright body 20. For example, the limiting groove 112 may be arranged along the circumferential direction and recessed inward from the ring member 201 at the end of the upright body 20. The limiting groove 112 may be engaged with the telescopic structure 111 provided in the limiting device. In response to the limiting groove 112 being coupled to the telescopic structure 111, the telescopic structure 111 may be accommodated in the limiting groove 112. Therefore, the upright body 20 may be coupled to the limiting device. Since the limiting device is coupled to the connecting portion 100, the connecting portion 100 may be coupled to the upright body 20.

[0045] Reference Figures 4 to 7 According to one embodiment of the present disclosure, the connection part 100 may include a housing 110 and a bracket 120 disposed at the bottom of the housing 110. The housing 110 may be substantially cylindrical, and the bracket 120 may be substantially annularly disposed at the bottom of the housing 110. The flexible suction tube 300 of the surface cleaning device may pass through the housing 110 and the bracket 120 to the fluid recovery path in the upright body 20. The flexible suction tube 300 may maintain the fluid patency when the connection part 100 and the upright body 20 are relatively pivoted, and does not twist with the relative pivoting of the connection part 100 and the upright body 20. The flexible suction tube 300 may maintain the fluid patency when the angle between the connection part 100 and the cleaning head 10 is changed (or when the angle between the upright body 20 and the cleaning head 10 is changed), and does not bend when the angle between the connection part 100 and the cleaning head 10 (or the upright body 20 and the cleaning head 10) is changed.

[0046] like Figure 6As shown, in some examples, the housing 110 may include a first pivot portion 110a and a second pivot portion 110b, configured to connect the housing 110 to the upright body 20 and the cleaning head 10 in a pivotable manner. The first pivot portion 110a may be arranged along a first direction so that the connection portion 100 and the upright body 20 can be axially pivoted around a first direction A while being connected. The second pivot portion 110b may be arranged along a second direction that is substantially perpendicular to the first direction so that the connection portion 100 and the cleaning head 10 can be axially pivoted around a second direction B while being connected.

[0047] Further Figure 6 and Figure 7 As shown, the bracket 120 is generally formed at the bottom of the housing 110 and maintains coaxiality with the main body of the housing 110. The bracket 120 includes a receiving portion 121 of a telescopic structure, which is used to receive the telescopic structure 111 on the bracket 120. In some examples, the telescopic structure 111 at least includes a limit pin 122 located in the receiving portion 121 and a spring return member 123 arranged around the limit pin 122. The limit pin 122 includes a driving end 122-2 and a free end 122-1. The spring return member 123 is arranged near the limit pin 122. The driving end 122-2 protrudes below the bracket 120 and can overcome the return action of the spring return member 123 under the application of external force, so that the driving end 122-2 moves upward to the limiting groove 112 of the upright body 20 to form a coupling between the connecting portion 100 and the upright body 20. In the coupled state, the relative pivoting between the upright body 20 and the connecting portion 100 is limited to a certain angle range. Generally, considering the safety needs, the angle range of the relative pivoting is set within an offset range with an absolute value not greater than 15° to ensure that a large angle of relative pivoting offset is avoided between the upright body 20 and the connecting portion 100 in the upright state. When the external force disappears, under the reset action of the spring reset member 123, the limit pin 122 is reset to the starting position relative to the bracket 120, and the free end 122-1 is disengaged from the limiting groove 112 of the upright body 20 to release the coupling between the connecting portion 100 and the upright body 20. In some examples, the receiving portion 121 of the telescopic structure may be disposed inside the housing 110.

[0048] In some examples, the external force that causes the driving end 122-2 to move is provided by the cleaning head 10. For example, when the user operates the handle 30 so that the upright body 20 is in a substantially vertical state relative to the cleaning head 10 (a self-standing state of the surface cleaning device), the trigger block on the cleaning head 10 releases the driving end 122-2 to generate an external force that actuates the driving end 122-2 to move. When the user operates the handle 30 so that the upright body 20 is in a non-vertical state relative to the cleaning head 10 (a working state of the surface cleaning device), the trigger block moves away from the driving end 122-2, the external force that actuates the driving end 122-2 to move disappears, and the limit pin 122 is reset under the reset action of the spring reset member 123.

[0049] like Figure 5 and Figure 8 As shown, the limiting groove 112 may be arranged on the annular member 201 at the annular port at one end of the upright body 20. The annular member 201 at the annular port forms a substantially annular pivot surface that pivots relative to the connecting portion 100. In some examples, the limiting groove 112 is formed on the pivot surface, and the limiting groove 112 may include a secondary limiting groove 112a and a main limiting groove 112b arranged within a circumferential range of 30°. The secondary limiting groove 112a may be formed from a surface depression of the pivot surface. The secondary limiting groove 112a may be formed into a shape corresponding to the lower end of the upright body 20. In some examples, the bottom of the secondary limiting groove 112a has a guide slope 112a1 toward the bottom of the main limiting groove 112b, which is configured to guide the free end 122-1 of the telescopic structure to move in a direction away from the main limiting groove 112b. When the upright body is in an upright non-aligned state, that is, when the free end 122-1 of the telescopic structure has deviated from the main limiting groove 112b and fallen into the secondary limiting groove 112a, in order to reliably limit the upright body in the secondary limiting groove 112a and prevent it from being separated from the secondary limiting groove 112a, thereby causing the upright body to deviate by an excessive angle, the free end 122-1 is guided to the bottom of the secondary limiting groove 112a by the guide slope 112a1 to prevent it from being separated. In some examples, the main limiting groove 112b is formed as a through hole that can penetrate the pivot surface. In response to the coupling of the upright body 20 with the connecting portion 100, the free end 122-1 of the limit pin 122 can pass through the main limiting groove 112b or abut against the bottom of the guide slope 112a1 of the secondary limiting groove 112a, thereby limiting the relative pivoting of the connecting portion 100 and the upright body 20.

[0050] The secondary limiting groove 112a may be arranged adjacent to the main limiting groove 112b. For example, the secondary limiting groove 112a is arranged adjacent to the main limiting groove 112b in the axial direction of the pivot surface. There may be multiple secondary limiting grooves 112. For example, two secondary limiting grooves 112a and one main limiting groove 112b may be provided and located on both sides of the main limiting groove 112b. The secondary limiting groove 112 may have a length distributed along the circumferential direction to facilitate providing the adaptability freedom when the connecting portion 100 and the upright body 20 are coupled. However, the form of the secondary limiting groove 112a is not limited thereto.

[0051] The surface cleaning device 1 according to one embodiment of the present disclosure may include a limiting device. The limiting device is configured to couple the upright body 20 to the cleaning head 10 or to separate the upright body 20 from the cleaning head 10. For example, the limiting device may couple the upright body 20 to the connecting portion 100 or to separate the upright body 20 from the connecting portion 100. The user may uncouple the upright body 20 from the connecting portion 100 by operating the handle 30 to change the relative angle between the upright body 20 and the cleaning head 10.

[0052] Typically, the connection portion 100 is generally capable of being in a first position and a second position relative to the cleaning head 10 around the B axis. For example, the connection portion 100 may be in a first position that may be at a larger angle with the cleaning head 10 or in a second position that may be at a nearly vertical angle with the cleaning head 10. The second position of the connection portion 100 may be a position in which the connection portion 100 is substantially perpendicular to the cleaning head 10. That is, the angle between the connection portion 100 and the cleaning head 10 may be approximately 90 degrees. Typically, an angle of approximately 90 degrees between the connection portion 100 and the cleaning head 10 may indicate that the user has stopped using the surface cleaning device. Therefore, in order to lock the connection portion 100 with the upright body 20 when the surface cleaning device is in an upright state, the connection portion 100 is coupled to the upright body 20 in response to the connection portion 100 being in the second position. Of course, the surface cleaning device 1 may also be operated (for example, in a self-cleaning state) when the connection portion 100 is in the second position. Therefore, the air (air containing foreign matter) sucked into the surface cleaning device 1 may pass through the air flow path and the recovery box of the surface cleaning device in sequence.

[0053] The first position of the connecting portion 100 may be that the connecting portion 100 is substantially in an inclined or horizontal position relative to the cleaning head 10. That is, the angle between the connecting portion 100 and the cleaning head 10 is greater than 90 degrees. Generally, an angle between the connecting portion 100 and the cleaning head 10 greater than 90 degrees may indicate that the user is using the surface cleaning device. Therefore, in order to unlock the connecting portion 100 and the upright body 20 during the operation of the surface cleaning device, in response to the connecting portion 100 being in the second position, the connecting portion 100 is decoupled from the upright body 20, thereby facilitating the user to operate the handle 30 to manipulate the upright body 20 and the cleaning head 10 to clean the surface to be cleaned.
