Description

Technical Field

[0001] This disclosure relates to a surface cleaning device. Background Technology

[0002] Surface cleaning devices are suitable for cleaning hard floor surfaces such as tile and hardwood, as well as soft floor surfaces such as carpet and upholstered surfaces. In the design of surface cleaning devices, a rotating mechanism is typically incorporated at the connection between the body and the floor brush to allow for rotation of the unit relative to the cleaning head. This rotating mechanism allows the unit to rotate around the floor brush, providing operational flexibility, such as adjusting the body angle during cleaning to adapt to different cleaning scenarios. Utility Model Content

[0003] This disclosure provides a surface cleaning apparatus, comprising:

[0004] An upright body is used to house the vacuum motor used to generate suction.

[0005] The recovery bin is located upstream of the vacuum motor;

[0006] A cleaning head with an airflow path can be connected to an upright body so that when the cleaning head is connected to the upright body, the suction generated by the vacuum motor can be used to guide foreign objects on the surface to be cleaned along the airflow path and collect them into the collection box.

[0007] A neck is positioned between the cleaning head and the upright body, connecting the cleaning head and the upright body;

[0008] The neck is capable of rotating about a first pivot axis relative to the upright body;

[0009] A retractable structure, arranged on one side of the neck, is configured to couple and decouple the neck and the upright body. In the coupled state, the rotation of the neck relative to the upright body about a first pivot axis is limited to a first angular range.

[0010] According to one example of this disclosure, the first angle range includes a range greater than or equal to -15° and less than or equal to 15°.

[0020] According to one example of this disclosure, the trigger is located on the cleaning head.

[0021] According to one example of this disclosure, the neck includes:

[0022] An outer shell;

[0023] A support frame, connected to the housing, and configured to receive a retractable structure; and

[0034] The present disclosure will now be described in further detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0035] It should be noted that, where there is no conflict, the examples and features in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and examples.

[0036] Unless otherwise stated, the exemplary examples / exemplaries shown are to be understood as providing exemplary features of various details that provide some ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various examples / exemplaries may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0037] In existing surface cleaning devices, this design presents a significant technical problem when the machine is in an upright position: due to gravity, the machine body is prone to uncontrolled rotation around the rotation axis of the cleaning head, causing it to tilt. This tilt not only affects the machine's balance, making it difficult to stand stably, but also poses a risk of tipping over, especially when stored or not in use. Excessive rotation and tilting degrade the user experience, requiring frequent adjustments to maintain upright position, and can also cause physical damage to the equipment, such as impacts to the ground leading to loosening or breakage of components. Therefore, a mechanism is needed to stabilize the machine body, limit its rotation in an upright position, and ensure the machine's balance and safety.

[0038] The limiting effect of existing technologies relies heavily on the precise alignment of the retractable structure with the hole. If the body fails to align correctly with the hole during reset (e.g., due to improper user operation or misalignment of the cleaning head), the free end of the retractable structure cannot smoothly enter the hole, causing the limiting function to fail. In this case, the body may still rotate around the cleaning head, resulting in excessive tilting or even tipping over. This alignment requirement increases the difficulty of user operation, especially when quickly adjusting the body's position. Users need to ensure that the relative positions of the body and the cleaning head are perfectly aligned; otherwise, the limiting mechanism will not function. This reliance on precise alignment creates safety hazards in practical use, especially in home environments where children or pets may accidentally touch the body, further increasing the risk of tipping over.

[0039] This disclosure provides a surface cleaning apparatus with an upright position limiting mechanism designed to enhance stability in an upright position. The apparatus includes an upright body housing a vacuum motor and a recovery tank, a cleaning head defining an airflow path (attached to the upright body to collect debris), and a connector pivotally connecting the cleaning head and the upright body. The connector rotates about a first pivot relative to the upright body and about a substantially perpendicular second pivot relative to the cleaning head, thereby enabling multi-directional adjustment. A retractable structure on the connector selectively couples or decouples the connector from the upright body, limiting rotation about the first pivot to a range of -15° to 15° in the coupled state. That is, in the coupled state, the upright body and the connector can be locked within a range of -15° to 15°. The upright body has a limiting groove structure with a main groove and adjacent secondary grooves circumferentially distributed within a 15° range for receiving the free end of the retractable structure, ensuring stability even in cases of misalignment. The triggering component on the cleaning head can activate the coupling in the upright position and release the coupling during operation, while the elastic reset component helps the retractable structure return to its original position.

[0040] This disclosure improves the upright stability and safety of surface cleaning devices compared to existing technologies. Unlike traditional designs that rely on precise alignment to limit rotation, this disclosure uses a main limiting groove and a secondary limiting groove to lock the upright body within a range of -15° to 15° in the upright state, reducing the risk of tipping even if it is not properly aligned with the connecting parts. This achieves a safe upright state, improves ease of use, and provides overall stability, safety, and ease of use compared to existing solutions.

[0041] Other aspects of this disclosure will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of the disclosure. An embodiment of this disclosure will now be described in detail with reference to the accompanying drawings.

[0046] In the following detailed description, terms such as "front side", "rear side", "left side", and "right side" may be defined by the accompanying drawings, but the shape and position of the parts are not limited by these terms.

[0047] Figure 1 A schematic diagram of the surface cleaning device 1 is provided, showing its main components: handle 30, upright body 20, connecting part 100 and cleaning head 10. Figure 1 This provides a basis for understanding the implementation of this disclosure. Reference Figure 1In a preferred embodiment, the surface cleaning device includes a handle 30 detachably mounted to the upright body 20, the body being pivotally connected to the cleaning head 10 via a connecting portion 100. The handle 30 is equipped with user interaction buttons for controlling the device's start / stop, liquid delivery rate, suction power, and optional functions such as enabling and adjusting the volume of a voice interaction system, enhancing the user experience.

[0048] The cleaning head 10 can use air suction to remove foreign objects (such as hair) from the surface to be cleaned. The cleaning head 10 can move on the surface to be cleaned while simultaneously removing dust and other foreign objects from the surface.

[0049] An airflow path can be formed inside the cleaning head 10. The airflow path formed inside the cleaning head 10 can be connected to the upright body 20 through the connecting part 100. External air and foreign objects introduced through the cleaning head 10 can move into the upright body 20 through the connecting part 100.

[0050] like Figure 2 As shown, the connecting part 100 can be rotatably connected to the cleaning head 10. As the connecting part 100 rotates around the cleaning head 10, the cleaning head 10 can rotate around the upright body 20 connected to the connecting part 100. Therefore, the degree of freedom of operation of the surface cleaning device 1 can be increased.

[0051] The upright body 20 forms part of the appearance of the surface cleaning device 1. One end of the upright body 20 can be mounted to the cleaning head 10. Specifically, one end of the upright body 20 is pivotally mounted to the connecting portion 100. The handle 30 is removably connected to the other end of the upright body 20. Relative to the cleaning head 10, the handle 30 can be operated to move the upright body 20 within a first angular range that limits the relative free pivoting of the connecting portion 100 and the upright body 20, and within a second angular range that maintains the relative free pivoting of the connecting portion 100 and the upright body 20.

[0052] According to some examples, the upright body 20 can be connected to the cleaning head 10. The connecting portion 100 can be coupled to both the upright body 20 and the cleaning head 10 to connect the upright body 20 to the cleaning head 10. For example, one end of the upright body 20 can be coupled to the connecting portion 100.

[0053] In some examples, such as Figures 1 to 3 The connecting portion 100 can be coupled to the lower end of the upright body 20 to restrict the pivotal degree of freedom of the upright body 20 relative to the connecting portion 100. The connecting portion 100 can be coupled to the upright body 20 by a limiting device. For example, as Figure 3 As shown, in the connecting part 100, the telescopic structure 111 provided in the limiting device can be engaged with the limiting groove 112 provided at the annular part 201 at the lower end of the upright body.

[0054] 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 restrict the relative pivoting between the cleaning head 10 and the upright body 20; or decouple the upright body 20 from the cleaning head 10 so that the cleaning head 10 and the upright body 20 can pivot independently while maintaining the connection. The user can change the relative position of the cleaning head 10 and the upright body 20 in the front-back direction (the operating direction of the surface cleaning device) by operating the handle 30 to couple and decouple the upright body 20 and the cleaning head 10 by means of the limiting device. The limiting device can be arranged on the opposite side of the connecting part 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 pivot locking between the connecting part and the upright body 20.

[0055] 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 port of the upright body 20. In some examples, the limiting groove 112 may be recessed inward from the annular member 201 at the port of the upright body 20. For example, the limiting groove 112 may be arranged circumferentially from the annular member 201 at the port of the upright body 20 and recessed inward. The limiting groove 112 may engage with a retractable structure 111 provided in the limiting device. In response to the coupling of the limiting groove 112 with the retractable structure 111, the retractable structure 111 may be accommodated within the limiting groove 112. Thus, the upright body 20 may be coupled with the limiting device. Since the limiting device is coupled with the connecting portion 100, the connecting portion 100 may be coupled with the upright body 20.

[0056] Reference Figures 4 to 7 According to one embodiment of the present disclosure, the connecting portion 100 may include a housing 110 and a support 120 disposed at the bottom of the housing 110. The housing 110 may be generally cylindrical, and the support 120 may be generally annularly disposed at the bottom of the housing 110. A flexible suction tube 300 of the surface cleaning device may pass through the housing 110 and the support 120 into a fluid recovery path within the upright body 20. The flexible suction tube 300 may maintain fluid flow when the connecting portion 100 and the upright body 20 pivot relative to each other, and may not twist with the relative pivoting of the connecting portion 100 and the upright body 20. The flexible suction tube 300 may maintain fluid flow when the angle between the connecting portion 100 and the cleaning head 10 changes (or when the angle between the upright body 20 and the cleaning head 10 changes), and may not be bent or compressed when the angle between the connecting portion 100 and the cleaning head 10 (or the upright body 20 and the cleaning head 10) changes.

[0057] 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 pivotally connect the housing 110 to the upright body 20 and the cleaning head 10, respectively. The first pivot portion 110a may be arranged along a first direction such that the connection portion 100 and the upright body 20 pivot about the first direction A while maintaining the connection. The second pivot portion 110b may be arranged along a second direction, which is substantially perpendicular to the first direction, such that the connection portion 100 and the cleaning head 10 pivot about the second direction B while maintaining the connection.

[0058] Further as 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 retractable receiving portion 121 for receiving the retractable structure 111. In some examples, the retractable structure 111 includes at least a limiting pin 122 located within the receiving portion 121 and a spring return member 123 surrounding the limiting pin 122. The limiting pin 122 includes a driving end 122-2 and a free end 122-1. The spring return member 123 is located near the limiting pin 122. The driving end 122-2 protrudes below the bracket 120 and can overcome the restoring action of the spring return member 123 under external force, causing the driving end 122-2 to move upward into 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 part 100 is limited to a certain angular range. Typically, for safety reasons, the angular range of relative pivoting is set within an absolute value of no more than 15° to ensure that, in the upright state, large relative pivoting offsets between the upright body 20 and the connecting part 100 are avoided. When the external force disappears, under the reset action of the spring reset member 123, the limiting pin 122 returns to its initial position relative to the bracket 120, and the free end 122-1 disengages from the limiting groove 112 of the upright body 20, thereby releasing the coupling between the connecting part 100 and the upright body 20. In some examples, the receiving part 121 of the retractable structure may be disposed inside the housing 110.

[0059] In some examples, the external force that causes the drive 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 perpendicular state relative to the cleaning head 10 (the self-standing state of the surface cleaning device), the trigger block on the cleaning head 10 releases the drive end 122-2 to generate an external force that actuates the drive end 122-2. When the user operates the handle 30 so that the upright body 20 is in a non-perpendicular state relative to the cleaning head 10 (the operating state of the surface cleaning device), the trigger block moves away from the drive end 122-2, the external force actuating the drive end 122-2 disappears, and the limiting pin 122 is reset by the reset action of the spring reset member 123.

[0060] like Figure 5 and Figure 8 As shown, a limiting groove 112 may be arranged on an annular member 201 at an annular port at one end of the upright body 20. The annular member 201 at this annular port forms a generally 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 primary limiting groove 112b arranged within a circumferential 30° range. The secondary limiting groove 112a may be recessed from the surface of the pivot surface. The secondary limiting groove 112a may be formed in a shape corresponding to the lower end 210 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 primary limiting groove 112b, configured to guide the free end 122-1 of the retractable structure toward a direction away from the primary limiting groove 112b. When the upright body is in an upright but not aligned state, that is, when the free end 122-1 of the retractable structure has deviated from the main limiting groove 112b and fallen into the secondary limiting groove 112a, in order to reliably restrict the upright body within the secondary limiting groove 112a and prevent it from disengaging from the secondary limiting groove 112a and causing the upright body to deviate by an excessive angle, the free end 122-1 is guided to the bottom of the groove of the secondary limiting groove 112a by the guide slope 112a1 to prevent disengagement. 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 and the connecting part 100, the free end 122-1 of the limiting 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 restricting the relative pivoting of the connecting part 100 and the upright body 20.

[0061] The secondary limiting groove 112a may be disposed adjacent to the primary limiting groove 112b. For example, the secondary limiting groove 112a may be arranged axially close to the primary limiting groove 112b on the pivot surface. There may be multiple secondary limiting grooves 112. For example, two secondary limiting grooves 112a and one primary limiting groove 112b may be provided, located on both sides of the primary limiting groove 112b. The secondary limiting grooves 112 may have a length distributed circumferentially to facilitate the adaptation degree of 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 to this.

[0062] A surface cleaning apparatus 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 detach 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 the connecting portion 100. The user may decouple the upright body 20 and the connecting portion 100 by operating the handle 30 to change the relative angle between the upright body 20 and the cleaning head 10.

[0063] Typically, the connecting portion 100 can be positioned in a first position and a second position relative to the cleaning head 10 about the B-axis. For example, the connecting portion 100 may be in a first position at a large angle to the cleaning head 10 or in a second position at a near-perpendicular angle to the cleaning head 10. The second position of the connecting portion 100 may be a position where the connecting portion 100 is substantially perpendicular to the cleaning head 10. That is, the angle between the connecting portion 100 and the cleaning head 10 may be approximately 90 degrees. Typically, an angle of approximately 90 degrees between the connecting 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 connecting portion 100 to the upright body 20 when the surface cleaning device is in the upright position, the connecting portion 100 is coupled to the upright body 20 in response to the connecting portion 100 being in the second position. Of course, the surface cleaning device 1 can also operate (e.g., in a self-cleaning state) when the connecting portion 100 is in the second position. Therefore, the air (air containing foreign matter) drawn into the surface cleaning device 1 can pass sequentially through the airflow path and the recovery box of the surface cleaning device.

[0064] The first position of the connecting portion 100 can be a position in which the connecting portion 100 is substantially inclined or horizontal 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 greater than 90 degrees between the connecting portion 100 and the cleaning head 10 may indicate that the user is using the surface cleaning device. Therefore, in order to unlock the connecting portion 100 from the upright body 20 during 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 control the upright body 20 and the cleaning head 10 to clean the surface to be cleaned.
