Description

Hand-held type surface cleaning device

Technical Field

The utility model relates to a surface cleaning utensil, concretely relates to hand-held type surface cleaning device.

Background

At present, various types of cleaning devices are commonly used in daily life, and common cleaning devices in the market, such as handheld dust collectors, are more and more familiar to consumers, and due to the advantages of portability and good controllability, the cleaning devices become the mainstream choice for consumers when selecting household dust collectors.

The handheld dust collector basically has two common design targets, firstly, the wireless design is realized, a power line does not need to be dragged in the using process, the operation feeling is improved, and the using environment is expanded; secondly, a lightweight and compact design is required to reduce the fatigue degree during use.

Among commercially available products, there is a very portable hand-held cleaner, which has a cylindrical structure, has an overall length approximately equal to that of an adult arm, can be held by one hand for operation, and is mainly used as a vehicle-mounted cleaner for cleaning an interior structure of a vehicle such as a seat back, and for cleaning a surface of furniture such as a surface of a table, a surface of a sofa, a surface of a cabinet, and the like. In summary, such hand-held cleaners are designed to address the need for cleaning in most situations where the operator is not required to bend down to reach the cleaning site. Obviously, compared with the traditional dust collector mainly used for cleaning the floor, the dust collector has the advantages that the connecting rod for connecting the cleaning head is shortened or omitted, and even the air inlet for dust collection is directly formed in the body, so that the overall compactness of the dust collector is obviously improved.

It is clear that this design is aimed at a portable hand-held cleaner, which is necessarily desired by consumers to be able to clean narrow spaces, such as gaps between furniture, and corners which are difficult to reach when flat, such as roofs, furniture tops … …, some of which require the operator to hold the hand-held cleaner with one hand and extend his arm as far as possible to clean the cleaning surface with the front end of the cleaner. Past product often can dispose different kinds of extension rod, and these extension rods can let the operator control hand-held type dust catcher in the position that goes the trunk near apart from the health and clean, and the inventor discovers when the product improves the research and development, and the appearance of extension rod has increased the whole length of dust catcher, runs counter with the design purpose of portability, can let the focus antedisplacement of dust catcher in addition, causes the tired sense of operation. Therefore, the cleaning machine has the advantage that an operator can straighten the arms as far as possible to clean the corners of a narrow space in a labor-saving mode.

The above description is included in the technical recognition scope of the inventors, and does not necessarily constitute the prior art.

Disclosure of Invention

In order to solve the above problem, the utility model provides a hand-held type surface cleaning device, include:

the body is provided with a front end provided with an air suction opening and a rear end opposite to the front end; the body is at least partially cylindrical;

a handle extending rearward from a rear end of the body;

the handle is arranged on the body, the rear end of the body is connected with the handle through a transition part, and the operating part is positioned on one side of the body; the transition part is positioned on the opposite side; and the distance between the operating piece and the connection part of the rear end of the body and the handle ranges from 10mm to 40 mm.

Obviously, with the above solution, the positional relationship between the operating member and the transition portion is such that when the user is holding the handle, the index finger of the user can be placed on the transition portion and the thumb of the user can touch the operating member. The user can be supported to control the operating part in a natural and relaxed mode through the thumb when holding the device with one hand.

Now, in order to support one-handed operation, determination of the holding position and the holding posture is critical, and after the holding position and the holding posture are determined, consideration needs to be given to making the whole process of the operation device more comfortable through an optimized design, and fatigue feeling reflected on the arm of an operator needs to be reduced as much as possible. This is advantageous in maintaining high cleaning efficiency, which otherwise would reduce the necessity for setting up the device to support one handed operation, as the operator would choose to clean for a period of time, and then retract the extended arms back around the torso for appropriate rest, as the operation of the device can be assisted by the other hand.

In a preferred embodiment, the centre of gravity of the device is located forward of the connection with the handle at the rear end of the body, at a distance of 20mm to 100mm from the connection with the handle at the rear end of the body.

Due to the inherent structure of the portable hand-held surface cleaning device, the device is compact, the weight of the device is concentrated, and the density of the device is improved on a macroscopic surface. This design is not itself friendly to achieve a sense of lightness during operation. In particular, the handheld vacuum cleaner is mainly used in a position where important cleaning is required, and the requirement for portability is very prominent. The light feeling is not only embodied in that the position and the angle of the device can be adjusted in a labor-saving way in the operation process, but also embodied in that the device is more labor-saving when the device is carried to move in a space needing to be cleaned.

When an operator uses the handheld cleaning device to clean and tidy the cleaning surface, the operator can hold the handle with the palm, and then the operator controls the handheld surface cleaning device to move and adjusts the placing angle of the handheld cleaning device by matching the wrist with the arm. In the cleaning process, the palm holds the handle to form the support to the device, and the holistic weight of device can apply the torque to the position of holding, mainly just resists this torque when the operator removes or rotates the device, and the torque has directly influenced the operation experience for the hindrance that controls and cause.

The gravity center of the whole device is arranged at the front side of the connection part of the rear end of the body and the handle, the moment arm of the torque formed by the weight of the whole device is the position of the gravity center to the hand-held handle, the length of the moment arm is set to be in the range of 20mm to 100mm, firstly, the length of the moment arm is controlled, and the holding force required to apply offset torque when the control device moves can be controlled to be in a smaller range; secondly, the torque applied to the handle by the integral device in the gripping position will tend to tilt the device towards the lower front of the handle, most of the time during cleaning, where the cleaning surface is generally horizontal, such as a counter or table top, and during cleaning, the operator will control the suction opening at the front end of the device to approach or be supported by the cleaning surface. Under this kind of operating mode, the focus position of so designing will reduce the dynamics that needs the extra applied power of controlling, and this power of controlling is mainly used for controlling the inclination that cleaning device need keep when cleaning, through the dynamics that reduces the power of controlling, can reduce fatigue to a certain extent and feel.

In addition, sometimes, a substantially vertical cleaning surface such as a wall, a curtain and the like is cleaned, at this time, the front end of the device is in a state of being inclined upward, the moment applied to a supporting point formed by the palm holding handle by the self weight of the device is divided into two directions of force, one is force substantially perpendicular to the extending direction, and the other is force for driving the front end of the device to be closer to the cleaning surface.

In one implementation, referring to fig. 10 and 11, a hand-held surface cleaning device is shown in a state of being held by a single hand, wherein the device includes a body 100 having a front end provided with an air suction opening and a rear end opposite to the front end; as shown, the body is at least partially cylindrical; a handle 200 extending rearward from the rear end of the body; wherein, the body 100 is provided with an operating part 170, a transition part 160 is formed at the connection part of the rear end of the body 100 and the handle 200, the operating part is arranged at one side of the body, and the transition part is arranged at the opposite side; in the implementation shown in fig. 11 and 12, the operation element 170 and/or the indication element; the operating member 170 and/or the indicating member is provided on an upper side surface of the rear end of the body 100 at the connection with the handle 200; the transition portion is formed on the lower surface of the device. And the distance range of the connection part of the rear end of the operating piece and the body and the handle is 10mm to 40 mm. The positional relationship of the operating member 170 to the transition portion 160 is such that when the user is holding the handle, the index finger of the user can be placed at the transition portion and the thumb of the user can touch the operating member.

The arrangement of the positional relationship between the transition portion and the operating member in the above-described aspect may be defined in such a manner that the operating member is disposed on one side of the surface of the body, and the transition portion is disposed for the index finger to be placed so that the operator can hold the handle in a substantially determined posture, and at this time, the root of the thumb is also supported on the surface of the body on the other side substantially opposite to the transition portion, it being understood that the thumb support portion is located in the position region where the distances from the rear end of the handle to the structures or elements are substantially within a range. This range is about 15mm to 30 mm. The operating parts are distributed in an operating area, and the distance between any point in the operating area and the center of the front position area is not more than the operating radius of the thumb. Therefore, the root of the thumb can be controlled to be supported in a position area corresponding to the transition part every time, such as the area defined by the two dotted lines in fig. 11, and the thumb can touch the operating part, so that when the device is held by one hand and the arm is straightened to clean the cleaning surface in the narrow space, the device can be controlled by one hand without additional assistance.

By such arrangement, when a user holds the handle with one hand, the thumb can contact with the operating piece arranged at any point in the area limited by the thumb operating radius, so that one or more operations such as starting, stopping, operating mode switching, operating state switching and the like of the device can be executed. As a particularly advantageous implementation, the operating member comprises a push button for performing an operation of opening the dust container, and the push button is arranged to be pushed forward to a first position and then to trigger the opening of the dust container for removing dust and other dirt from the dust container, and then to slide back to the original position under the action of the spring force when the push button is acted on by an external force. The push button is very suitable for being operated by a single hand, so that the comfort degree of thumb operation can be improved to a certain extent, and the fatigue feeling is reduced.

Of course, the above description of the arrangement of the operating region may also be defined in other ways, not limited to the above-mentioned exemplary way, it being understood that, based on the "positional relationship of the operating member to the transition portion being satisfied, when the user is holding the handle, the index finger of the user can be placed on the transition portion and the thumb of the user can touch the operating member. The technical idea of the invention is to select other suitable criteria to determine the setting range of the position area for supporting the root of the thumb under different conditions, and the difference of the selected criteria does not affect the setting range of the position area.

In one implementation, the hand-held surface cleaning apparatus is configured as described with reference to fig. 1, the apparatus comprising: a body 100 having a front end (forward direction indicated by arrow F in the drawing) where the air suction opening 110 is provided and a rear end (backward direction indicated by arrow B in the drawing) opposite to the front end; the body 100 is at least partially cylindrical; a handle 200 extending backward from the rear end of the body 100, the handle 200 being at least partially cylindrical; as shown, the center of gravity of the device is located forward of the connection point of the rear end 120 of the body and the handle 200, and the distance L1 from the center of gravity to the connection point of the rear end 120 of the body and the handle 200 can be set to a value ranging from 20mm to 100 mm.

Through the distribution of rationally arranging device inside and outside spare part and adjusting device's outside profile, can realize the adjustment to the device focus, dispose focus in aforementioned position, be favorable to improving the operation experience that the operator used hand-held type cleaning device to carry out clean and tidy time to clean surface. When an operator holds the handle by hands, the hand-held surface cleaning device is controlled to move and the placement angle of the hand-held cleaning device is adjusted by matching the wrist with the arm. In the cleaning process, the palm holds the handle to form the support to the device, and the holistic weight of device can apply the torque to the position of holding, mainly just resists this torque when the operator removes or rotates the device, and the torque has directly influenced the operation experience for the hindrance that controls and cause.

The gravity center of the whole device is arranged at the front side of the connection part of the rear end of the body and the handle, the moment arm of the torque formed by the weight of the whole device is the position of the gravity center to the hand-held handle, the length of the moment arm is set to be in the range of 20mm to 100mm, the length of the moment arm is controlled firstly, and the holding force required to apply offset torque when the control device moves can be controlled to be in a smaller range.

Secondly, the torque applied to the handle by the integral device in the gripping position will tend to tilt the device towards the lower front of the handle, most of the time cleaning is performed on a substantially horizontal cleaning surface such as a counter or table top, and referring to fig. 12, the operator will control the suction opening at the front end of the device to be close to or supported on the cleaning surface when the hand-held cleaning device with the same center of gravity configuration is used for cleaning. Under this kind of operating mode, the focus position of so designing will reduce the dynamics that needs the extra applied power of controlling, and this power of controlling is mainly used for controlling the inclination that cleaning device need keep when cleaning, through the dynamics that reduces the power of controlling, can reduce fatigue to a certain extent and feel.

In addition, sometimes, there is also a cleaning surface that is substantially vertical, such as a wall, a curtain, etc., and referring to fig. 13, at this time, the device will be in a state that the front end is substantially inclined upward, and the moment that the self-weight of the device applies to the supporting point formed by the palm-holding handle will be divided into two directions, one is a force that is substantially perpendicular to the extending direction, and the other is a force that drives the front end of the device closer to the cleaning surface.

In a preferred implementation, in conjunction with fig. 1, the average radial dimension of the body 100 will be set greater than the average radial dimension of the handle 200. Specifically, in connection with FIG. 5, the thickness H1 of the handle 200 will be less than the thickness H2 of the body 100, and in connection with FIG. 6, the width B1 of the handle 200 will be less than the width B2 of the body 100.

The radial dimension of the handle is set smaller than that of the body, which facilitates comfortable holding and also meets the requirement of reserving the arrangement space of the internal elements.

In an alternative implementation of the aforementioned gravity center arrangement, referring to fig. 2, a dust box 130, a filter 140 and a suction motor 150 are provided in the body 100; a battery 210 is provided in the handle 200, and the weight of the battery 210 is controlled to be less than the sum of the weights of the dust box 130, the filter 140, and the suction motor 150.

In this way, the suction motor with heavier weight is arranged in the body, the battery is placed in the handle, and on the premise of meeting the normal use capacity of the battery, the weight of the battery is designed to be lighter than the suction motor or the sum of the weights of the dust collection box, the filter and the suction motor, so that the gravity center of the whole device is naturally distributed to the position, at which the front side of the connection part of the rear end of the body and the handle is not too far away. Meanwhile, the battery is arranged on the handle, the handle can be detachably connected with the body, the battery is detached by detaching the handle, and separated charging is carried out, so that one set of device can be provided with a plurality of batteries. In other implementations, the handle will be integrally formed with the body by reducing the number of connections to improve the overall compactness of the device.

In an alternative implementation, referring to fig. 3, the axis of the dust bin 130, the axis of the filter 140, and the axis of the suction motor 150 will generally coincide with a common axis.

The dust collecting box, the filter and the suction motor are coaxially arranged, the force arms of the torque which is independently applied to the holding position by the dust collecting box, the filter and the suction motor are approximately parallel, the trend that the torque which is integrally applied to the holding position by the device changes along with the angle is expected, and the distribution of internal elements of the device and the structure of an accommodating space are facilitated.

In an alternative implementation, referring to fig. 4, the axis of the battery 210 is parallel to at least one of the axis of the dust box 130, the axis 140 of the filter, and the axis of the suction motor 150.

The axis of the battery is arranged to be approximately parallel to the axis of the element in the body, so that the moment change of the device is more regular.

It should be understood that the above-mentioned axes, in various implementations of the present invention, indicate the geometric centerlines of the various partial structures.

In an alternative implementation, and with reference to any of fig. 7-10, the transition is formed in a manner that includes a recess 160.

The concave part formed at the connecting position of the handle and the body can drive a user to place an index finger in the concave part when the user naturally holds the handle, the supporting position formed by holding the handle by a palm is driven to be approximately kept fixed, the moment applied to the supporting position by the self weight of the device is approximately kept stable, and it needs to be explained that the change of the stable indicating moment is driven to be regular, and the moment applied to the supporting position by the self weight of the device is approximately consistent when the device is placed at the same angle.

As a preferred arrangement, the depth of the recess, i.e. the depth of the bottom of the recess relative to the outer surface of the handle, is 5mm to 15 mm. The size range is designed according to human engineering, the index finger of the palm can be hooked on the concave part in a comfortable way, the holding position is indicated, the holding firmness can be increased, the stability of the device is kept, and the control force is favorably exerted.

In addition, referring to fig. 8, a side of the recess 160 adjacent to the handle 200 is formed with a raised stopper rib 1601.

The convex limiting ribs can indicate the positions of the concave parts more clearly and can play a certain anti-slip role, when water stains or sweat are attached to the palm, the convex limiting ribs serve as a stop structure, the forefinger can be prevented from slipping out, and particularly the device can be prevented from slipping out of the palm during holding. When the device is carried and the device is moved, the limiting ribs are matched with the concave parts to form support in the vertical direction, so that the device is prevented from being loosened and slid from the palm carelessly.

The provision of actuation elements such as buttons and indicators, arranged on the upper side of the junction of the handle and the rear end of the body, allows the device to be operated with one hand, for example, by holding it with one hand and using the thumb to operate the relevant element. In a more preferred implementation, the operation button can be a power switch, and can also be a button for controlling and triggering to open the dust box.

Furthermore, as shown in the figures, the operating member is preferably located at the junction of the body and the handle, i.e., forward of the region forming the transition portion, to support the thumb to be manipulated in an extended state, increasing comfort.

Finally, as a clear characterization of the device described in the various implementations of the invention, it is preferred that the front end of the body of the device is 240mm to 400mm from the connection with the handle at the rear end of the body. That is, the functional components or parts other than the handle are integrated in such a length range, i.e. the solution of the invention is more suitable for products that can be considered as "mini" or "portable" cleaners. Of course, the present invention is not limited to the above products in the case of the same technical concept.
