[0019] The present disclosure will be further described in greater detail by way of specific embodiments, reference being made to the following description and to the attached drawings in which:

[0020] It should be noted that the embodiments and features of the present disclosure can be combined with each other, as long as there is no conflict. The technical solutions of the present disclosure will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] Unless otherwise indicated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of a way in which the inventive concept(s) of the present disclosure can be put into practice. Thus, unless otherwise specified, features of the various embodiments / examples can additionally be combined, separated, interchanged, and / or rearranged, without departing from the inventive concept(s) of the present disclosure.

[0022] The use of cross-hatching and / or shading in the drawings is generally used to indicate different regions within the same component and is not intended to indicate or suggest any preference or requirement for particular materials, material properties, dimensions, proportions, commonality of the illustrated components, and / or any other characteristics, attributes, properties, etc. of the components. Moreover, in the drawings, the size and relative sizes of components can be exaggerated for clarity and / or descriptive purposes. When exemplary examples can be otherwise identical, a particular process sequence can be performed in a different order than described. For example, two sequentially described processes can be performed at substantially the same time or in the reverse order described. Also, like reference numerals denote like components.

[0023] When a component is referred to as being “on” or “over”, “connected to” or “coupled to” another component, it can be directly on, connected, or coupled to the other component, or intervening components can be present. When a component is referred to as being “directly on”, “directly connected to”, or “directly coupled to” another component, there are no intervening components present. The term “connected” can refer to physical or electrical connection, with or without intervening components.

[0024] For descriptive purposes, the present disclosure can use spatial or relative terms, such as “below”, “lower”, “under”, “underneath”, “below”, “down”, “up”, “above”, “over”, “higher”, and “side” (e.g., as in “sidewall”) to describe the relationship between one component and another component as the figure(s) are oriented. The spatial or relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “under” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. Moreover, the device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatial or relative descriptors used herein interpreted accordingly.

[0025] The terminology used herein is for the purpose of describing specific examples and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not preclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent deviations in measurements, calculations, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0026] Most existing portable surface cleaning devices that are easy for users to hold use a single, straight frame. Due to their small overall size, they are suitable for quick cleaning of various small surfaces, such as desktops and car interiors. Their compact size also makes them easy for users to store and place. However, the straight frame also limits the angle at which the user can hold the surface cleaning device. For example, in some confined spaces, users need to adjust the angle between the straight frame and the surface to be cleaned to achieve a clean result, which can be inconvenient for users.

[0027] This disclosure provides a portable surface cleaning device with multiple possible fixing methods, making it more convenient to use and adaptable to more cleaning environments.

[0028] Figure 1 A portable surface cleaning device 100 according to one embodiment of the present disclosure is shown. Figure 1 As shown, the portable surface cleaning device 100 includes a main body 101 extending along a longitudinal axis L from a first end 1011 to a second end 1012. The interior of the main body 101, from the first end 1011 to the second end 1012, sequentially includes a motor assembly 103, a filter assembly 104, a dust cup assembly 105, and a nozzle assembly 106. The main body 101 may include a housing 107 with a substantially uniform outer diameter extending from the first end 1011 to the second end 1012. In one embodiment, the nozzle assembly 106 and / or the filter assembly 104, etc., are detachable. The main body 101 includes a release button 108 operable to slide, unlocking or locking the nozzle assembly 106, causing the nozzle assembly 106 to change direction and angle relative to the main body 101 about a pivot assembly 110.

[0029] The portable surface cleaning apparatus 100 includes a handle portion 102 adjacent to a first end 1011 of the main body portion 101. The handle portion 102 is used during operation to be held by a user to operate the portable surface cleaning apparatus 100 in various directions. The handle portion 102 of the portable surface cleaning apparatus 100 also includes a switch activation key 109 that can be activated by the user while holding the handle portion 102 to power on and off the portable surface cleaning apparatus 100, adjust the power setting of the motor, and the like.

[0030] The motor assembly 103 of the main body portion 101 can include a control circuit to selectively power a motor disposed therein. The motor can be a direct current motor or other suitable motor to generate suction. The motor generates suction to draw air into the suction nozzle assembly 106.

[0031] The dust cup assembly 105 can be configured to receive and store dust and debris received through the suction nozzle assembly 106. The suction nozzle assembly 106 is rotatably coupled to the dust cup assembly 105 through a pivot assembly 110. Thus, the suction nozzle assembly 106 can be rotated along a first rotational axis and stopped at an angle of not less than a right angle to the longitudinal axis 116 of the main body portion 101 when released, for example, by a release button 108. The suction nozzle assembly 106, when open, the dust cup assembly 105 forms an open mouth that can be used to pour dust and debris from the open mouth of the dust cup assembly 105. Thus, the suction nozzle assembly 106 can be switched between a closed orientation and an open orientation.

[0032] As Figure 1 shown, the handle portion 102 defines a receiving cavity 1021 that can receive one or more rechargeable batteries 111.

[0033] The receiving cavity 1021 defined by the handle portion 102 is in communication with the interior of the main body portion 101. The main body portion 101 houses the motor assembly 103 therein. Along the longitudinal axis L, the filter assembly 104 is disposed before the motor assembly 103. As Figure 1 shown, the filter 124 is a straight-through filter, but cyclonic filter arrangements are within the scope of the present disclosure.

[0034] Figure 2 An exemplary embodiment of the portable surface cleaning apparatus 100 is shown in a folded configuration. As Figure 2 shown, the handle portion 102 of the portable surface cleaning apparatus 100 is rotatably movably coupled to the main body portion 101 through a swivel joint 300. In Figure 1 the straight configuration, the portable surface cleaning apparatus 100 has a generally elongated cylindrical shape. In Figure 2In the illustrated bent configuration, the portable surface cleaning apparatus 100 has a generally L-shaped shape.

[0035] The handle portion 102 has a rechargeable battery 111 therein, and the body portion 101 has a motor assembly 103 disposed therein. The motor assembly 103 can be coupled to the rechargeable battery 111 via an electrical wire. Figure 2 An electrical wire routing path W, shown as a dashed line, is shown formed between the rechargeable battery 111 and the motor assembly 103. The electrical wire routing path W includes internal electrical wires therein for delivering electrical power to the electronics in the body portion 101, at least one of which traverses the extension to the interior of the body. A swivel joint 300 formed between the handle portion 102 and the body portion 101 can be articulated via user operation to change the configuration of the portable surface cleaning apparatus 100 and the electrical wire routing path W from a straight configuration to a bent configuration or an angled configuration. As Figure 2 As shown, as a result of the articulation of the swivel joint 300, the handle portion 102 and the body portion 101 are angled relative to each other. As a result, the electrical wire routing path W, shown as a dashed line, is bent between the handle portion 102 and the body portion 101.

[0036] As can be appreciated by those skilled in the art, the handle portion 102 and the body portion 101 of the portable surface cleaning apparatus 100 can be relatively fixed by the swivel joint 300 at any position between a position in which the portable surface cleaning apparatus 100 is in a straight configuration and a position in which the portable surface cleaning apparatus 100 is in an angled configuration to operate the portable surface cleaning apparatus 100 for cleaning in different environments while keeping the electrical wire routing path W always on. In other aspects, the swivel joint 300 can be configured to prevent the electrical wire routing path W from being twisted beyond its connection limits on the circuit board of the rechargeable battery 111 and / or the control board of the motor assembly 103. As Figure 1 As shown, the portable surface cleaning apparatus 100 can be configured in a fully straight configuration in which the swivel joint 300 locks the body so as to be in longitudinal alignment with the handle portion 102. Figure 2 As shown, the portable surface cleaning apparatus 100 can be configured in a fully bent configuration in which the swivel joint 300 locks the body portion 101 and the handle portion 102 at a generally perpendicular angle. The portable surface cleaning apparatus 100 can also be configured in a swivel configuration in which the swivel joint 300 positions and locks the body in an angled position relative to the handle portion 102 in a range of positions between the fully straight configuration and the fully bent configuration.

[0037] As indicated above, the body portion 101 and the handle portion 102 mate to each other at a rotary joint 300. The rotary joint 300 can have various configurations, but in the illustrated embodiment it includes a hinged structure configured with respect to the handle portion 102 and the body portion 101. The rotary joint 300 can be rotated in a first direction to an angled configuration and locked, and in a second direction to return to a straight configuration. In particular, the rotary joint can include a handle hinge on the handle and a body hinge on the body. The handle hinge includes a first mating piece configured to rotationally couple the handle to the body frame; the body hinge includes a second mating piece configured to rotationally couple the body to the handle frame, e.g., the first mating piece is locked to the body and / or the second mating piece is locked to the handle assembly in the straight and / or the folded configurations.

[0038] The handle portion 102 can also include a user interface for enabling a user to provide inputs for operating the portable surface cleaning device 100 and displays. The user interface can include the switch operation key 109 described above for powering the portable surface cleaning device 100 on and off, adjusting the power setting of the motor. The user interface can also include display prompts such as battery status display, dirt particle concentration display, etc.
