Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.

The present application provides a cleaning device with a handle and a handle mounted on a manually operated mobile device, and the structure and operation of the cleaning device and the handle are described below with specific embodiments. It should be noted that the embodiments described below are only examples of a part of the present application, and not all examples. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. To facilitate understanding of the cleaning device of the present application, the structure of the handle mounted on the cleaning device will be described in detail.

First embodiment

A first embodiment of the present application provides a handle for mounting on a manually operated mobile instrument, which in this embodiment can be held by one hand as well as both hands. Fig. 1 and fig. 2 are schematic structural diagrams of a handle of a first embodiment of the present application in different states, respectively. Fig. 1 is a schematic structural view of a grip on a handle in a state where a handle body is held by one hand, and fig. 2 is a schematic structural view of a grip on a handle in a state where the grip can be held by two hands. In order to facilitate observing the internal structure of the handle, the application provides fig. 3 to 5, and fig. 3 to 5 can illustrate the disassembled structural schematic diagram of each component on the handle. The structure and the operation principle of the handle of the present embodiment will be explained in detail below.

Referring to fig. 1 to 5, the handle of the present embodiment includes a handle body 101, a handle 102 mounted on the handle body, and a lock element 103. The handle 102 has two states: a closed state in which the handle body 101 is held by one hand, and an open state in which the grip 102 is held by both hands. Specifically, in this embodiment, it should be noted that when the handle 102 is in the closed state that facilitates the handle body 101 to be held by one hand, the user can hold the front end of the handle by one hand, and when the handle 102 is in the open state that enables the handle to be held by two hands, the user can hold the first handle 102-1 and the second handle 102-2 of the handle 102 by two hands.

Specifically, the handle 102 includes a first handle 102-1 and a second handle 102-2 (the first handle 102-1 and the second handle 102-2 are not shown simultaneously in FIG. 1, and the first handle 102-1 and the second handle 102-2 are shown simultaneously in FIG. 2). Referring to fig. 1, fig. 1 illustrates a handle 102 on a handle in a state that the handle body 101 is held by a single hand, and at this time, it can be seen from fig. 1 that a first handle 102-1 and a second handle 102-2 are in a fitting state. Referring to fig. 2, fig. 2 illustrates the handle 102 in a state of being held by both hands, and it can be seen from fig. 2 that the first handle 102-1 and the second handle 102-2 are in an open state. When first handle 102-1 and second handle 102-2 are in an open position, first handle 102-1 and second handle 102-2 are symmetrical about lock member 103.

Of course, it is understood that the state of the handle 102 shown in fig. 1 in which the handle body 101 is held by one hand and the state of the handle 102 shown in fig. 2 in which the handle body 102 is held by both hands are examples, and do not mean that the handle body 101 can be held by one hand only in the state shown in fig. 1, or that the handle 102 can be held by both hands only in the state shown in fig. 2. For example, when the angle between the first handle 102-1 and the second handle 102-2 is a certain angle, the lock member 103 can lock the first handle 102-1 and the second handle 102-2 of the two handles of the handle 102 so that the first handle 102-1 and the second handle 102-2 of the two handles of the handle 102 cannot rotate, and at this time, the first handle 102-1 and the second handle 102-2 can be locked in the current state. Such a state in which the first handle 102-1 and the second handle 102-2 are at an angle and the first handle 102-1 and the second handle 102-2 cannot be rotated can be actually taken as an example of a state in which the extension handle 102 can be held by both hands.

In the present embodiment, the handle 102 has a closed state that facilitates the handle body 101 to be held by one hand, an open state that facilitates the handle 102 to be held by both hands, and is capable of being switched between the closed state and the open state, depending on the structure and the operation principle of the lock member 103. Specifically, the lock member 103 has a locked position and an unlocked position, and when the lock member 103 is located at the unlocked position, the handle 102 can be switched between the closed state and the open state; when the lock member 103 is located at the lock position, the handle 102 is locked in the current state. Specifically, when the lock member 103 is located at the unlocking position, the handle 102 may be rotated to a suitable position or angle, and then the lock member 103 is located at the locking position, so that the handle 102 is switched between a state of being held by both hands and a state of facilitating the grip of the handle body 101 by one hand.

For example, when a user needs to use the manually-operated mobile device with the handle of the present embodiment, taking the handheld cleaning device as the manually-operated mobile device as an example, the user can hold the handheld cleaning device with one hand or both hands, and the handheld cleaning device can be switched between the one-hand holding state and the two-hand holding state.

For example, when the grip 102 on the handle on the hand-held cleaning device is in the state shown in fig. 1, the user can hold the handle with one hand by having the lock member 103 in the locked position. If the lock element 103 is located at the unlock position, the first handle 102-1 and the second handle 102-2 of the handle 102 may be rotated, and when the first handle 102-1 and the second handle 102-2 are rotated to a suitable angle or position, the lock element 103 may be set to the lock position, so as to lock the first handle 102-1 and the second handle 102-2 in the current state, for example, the first handle 102-1 and the second handle 102-2 may be locked in the state shown in fig. 2, and at this time, the user may hold the handles with both hands, which realizes the conversion of the handheld cleaning apparatus from the one-hand holding state to the two-hand holding state.

Similar to the above procedure, it is also possible to switch the hand-held cleaning device from a two-handed holding state to a one-handed holding state, e.g. when the grip on the handle on the hand-held cleaning device is in the state shown in fig. 2, the user can hold the handle with both hands by setting the lock member 103 to the locked position. If the lock element 103 is located at the unlock position, the first handle 102-1 and the second handle 102-2 of the handle 102 can be rotated, and when the first handle 102-1 and the second handle 102-2 are rotated to a suitable angle or position, the lock element 103 can be set to the lock position, so as to lock the first handle 102-1 and the second handle 102-2 in the current state, for example, the first handle 102-1 and the second handle 102-2 can be locked in the state shown in fig. 1, and at this time, the user can hold the handles with one hand, which realizes the conversion of the handheld cleaning device from the two-hand holding state to the one-hand holding state.

It should be noted that the handle 102 can be switched between the closed state and the open state when the lock member 103 is located at the unlocking position, and the handle 102 is locked at the current state when the lock member 103 is located at the locking position, and the structure of the lock member 103 will be described in detail below in connection with the structure of the lock member 103.

In particular, the locking element 103 may be realized with an axial component. Please refer to fig. 3, which is a schematic structural diagram of a lock component according to a first embodiment of the present application.

The axial member is mounted on the handle body 101 and can be operated by the user to be in an unlocked position and a locked position; the handle 102 is coupled to the handle body 101 by being fitted to the axial member. Namely: in this embodiment, the grip 102 is mounted on the grip body 101 through the axial member by being fitted over the axial member. In order to facilitate the pushing and pulling of the axial component, the pushing and pulling component 103-3 is arranged on the axial component, and the axial component can be respectively positioned at an unlocking position and a locking position by pushing and pulling the pushing and pulling component 103-3 on the axial component. Specifically, the push-pull member 103-3 may be a push-pull button, and of course, the push-pull member 103-3 may be a member other than the push-pull button, which is convenient for the user to perform the push-pull operation.

In this embodiment, the lock member 103, i.e., the axial member, moves in the extending direction along the grip portion 101-1 (shown in fig. 2) of the handle body 101, the grip portion 101-1 of the handle body 101 is a portion that is gripped by a single hand of a user when the user performs a cleaning operation using the cleaning apparatus, and when the push-pull member 103-3 is pressed, the axial member moves forward (cleaning apparatus advancing direction) in the extending direction of the grip portion 101-1 of the handle body 101, and when the push-pull member 103-3 is pulled out or pushed out, the axial member moves backward (cleaning apparatus retreating direction) in the extending direction of the grip portion 101-1 of the handle body 101. The direction of movement of the axial component is not coplanar with the plane of rotation of the first handle 102-1 and the second handle 102-2. In another embodiment, the lock element 103, i.e., the axial member, can move back and forth in the horizontal direction, and when the push-pull member 103-3 is pressed, the axial member moves forward in the horizontal direction (cleaning device forward direction), and when the push-pull member 103-3 is pulled out or pushed out, the axial member moves backward in the horizontal direction (cleaning device backward direction). At this time, the direction of movement of the axial components is perpendicular to the plane of rotation of the first handle 102-1 and the second handle 102-2.

In the present embodiment, in order to clearly illustrate how the axial member and the handle 102 are mounted on the handle body 101 together, and to realize the process of switching the handle 102 between the closed state and the open state, the following is explained in detail with reference to fig. 1, 4 and 5. Fig. 4 is a schematic structural diagram of the handle 102 locked by the lock element 103 according to the first embodiment of the present application, and fig. 5 is a schematic structural diagram of the handle 102 unlocked by the lock element 103 according to the first embodiment of the present application.

Specifically, the handle body 101 is provided with a mounting position (not shown in the figure). The handle 102 is provided with a mounting hole 102-3. The axial member is inserted through the mounting hole 102-3 to be coupled to the handle 102 and further inserted into the mounting position, so that the handle 102 is mounted on the handle body 101. In the present embodiment, the mounting position provided on the grip body 101 may refer to a relevant portion of the coupling position of the mounting hole that receives the grip 102, and a hole of the axial member.

To facilitate locking or unlocking the handle 102 with the axial member, the axial member may be designed to include a first portion 103-1 and a second portion 103-2 as schematically shown in FIG. 3. The main reason why the axial member is designed to include a first portion 103-1 and a second portion 103-2 is that when the position where the axial member is received in the mounting hole 102-3 is located in the first portion 103-1, the axial member can lock the handle 102, that is: the first handle 102-1 and the second handle 102-2 are in a locked state and are not free to rotate relative to each other. When the position where the axial component is sleeved with the mounting hole 102-3 is located at the second portion 103-2, the axial component unlocks the handle 102, and the handle 102 can rotate around the axial component, that is: the first handle 102-1 and the second handle 102-2 are in an unlocked state and can rotate freely with the axial component as an axis. In the present embodiment, specifically, when the push-pull member 103-3 is pressed, the position where the axial member is fitted into the mounting hole 102-3 is located at the second portion 103-2, and the axial member unlocks the knob 102; when the push-pull member 103-3 is restored (pulled out from the pressed state), the position where the axial member is fitted into the mounting hole 102-3 is located at the first portion 103-1, and the axial member locks the knob 102.

In this embodiment, when the axial component is pushed or pulled, in order to facilitate determining the extent of the pushing or pulling, the lock element 103 is changed from the initial locking position to the unlocking position, which can be determined by the movement stroke of the axial component during the pushing or pulling process. Specifically, when the moving stroke of the axial component reaches the length of the first portion 103-1 in the axial direction of the axial component, or the sum of the sizes of the rotary joints of the first handle 102-1 and the second handle 102-2 in the axial direction of the axial component, the lock element 103 is changed from the locked position to the unlocked position.

In order to return the lock element 103 from the unlocked position to the initial locked position when the axial member is pushed or pulled, a mechanical return structure or an electrical return structure is also mounted on the handle. Specifically, when the lock element 103 is in the unlocked position, and the first handle 102-1 and the second handle 102-2 of the handle 102 are rotated to the locked position, the lock element 103 is triggered to return to the original locked position by triggering the mechanical reset mechanism or the electric reset mechanism. The mechanical or electrical reset mechanism described above can trigger the reset of the lock element 103.

It is understood that, in this embodiment, when the push-pull member 103-3 is pulled out, the position where the axial member is sleeved with the mounting hole 102-3 is located at the second portion 103-2, and the axial member unlocks the handle 102; when the push-pull member 103-3 is restored (pressed back from the drawn state), the position where the axial member is fitted into the mounting hole 102-3 is located at the first portion 103-1, and the axial member locks the knob 102, in which case the mutual positional relationship of the first portion 103-1 and the second portion 103-2 is opposite to the structure shown in fig. 3, that is: in this case, the first portion 103-1 is directly connected with the push-pull member 103-3 while the first portion 103-1 is connected with the second portion 103-2. That is, in this structure, the positions of the first portion and the second portion are exchanged compared to those of fig. 3.

More specifically, in order to allow the axial member to lock the handle 102 when the position where the axial member is fitted into the mounting hole 102-3 is located at the first portion 103-1; meanwhile, when the position where the axial member is fitted in the mounting hole 102-3 is located in the second portion 103-2, the axial member unlocks the handle 102, and in this embodiment, the inner circumferential surface of the mounting hole 102-3 may be provided as a non-circumferential surface; correspondingly, the outer peripheral surface of the first portion 103-1 is provided with a shape and a size matching the shape and the size of the inner peripheral surface of the mounting hole 102-3, and has a non-circular shape so that the axial member locks the knob 102 when the position where the axial member is fitted into the mounting hole 102-3 is located in the first portion 103-1. Of course, the non-circular shape is only a theoretical possibility, and in practice, the shape is selected at least to achieve a snug fit of the outer circumference of the first portion 103-1 with the inner circumference of the mounting hole 102-3 in both the closed and open states, as required to enable the handle to be locked. In a more obvious alternative, the inner circumferential surface of the mounting hole is a regular polygon with even number of sides; correspondingly, the shape of the outer peripheral surface of the first part 103-1 of the axial component adopts the same regular polygon and has the size matched with the inner peripheral surface of the mounting hole; the handle and the lock element have the following number of position states between the closed state and the open state, which enable locking: the number of edges is divided by 2.

Specifically, referring to fig. 4, fig. 4 illustrates an example of matching the shape and size of the outer peripheral surface of the first portion 103-1 with the shape and size of the inner peripheral surface of the mounting hole 102-3, as can be seen from fig. 4: the inner peripheral surface of the mounting hole 102-3 is square, the outer peripheral surface of the first portion 103-1 is also square, and the two are just of a size which enables the first portion 103-1 and the mounting hole 102-3 to be matched with each other to realize sleeve connection, and at the moment, the axial component locks the handle 102.

Meanwhile, the outer circumferential surface of the second portion 103-2 may be shaped as a circumferential surface as illustrated in fig. 5, and when the outer circumferential surface of the second portion 103-2 is shaped as a circumferential surface, the circumferential surface needs to have a size capable of being fitted into the inner circumferential surface of the mounting hole 102-3, so that the axial member unlocks the handle 102 when the position where the axial member is fitted into the mounting hole 102-3 is located in the second portion 103-2.

In the present embodiment, when the inner peripheral surface of the mounting hole 102-3 is provided in a square shape; correspondingly, the outer peripheral surface of the first portion 103-1 is also provided with a square shape. The handle 102 and the lock member 103 are lockable in two states between a closed state and an open state (including a closed state and an open state). These two states are a closed state as shown in fig. 1 and an open state as shown in fig. 2, respectively.

In the present embodiment, except that the inner peripheral surface of the mounting hole 102-3 and the outer peripheral surface of the first portion 103-1 are provided in a square shape having a size matching. The inner peripheral surface of the mounting hole 102-3 and the outer peripheral surface of the first portion 103-1 may be provided in other regular polygonal shapes having matching sizes. Of course, the number of sides of other regular polygons should be even. For example, the inner peripheral surface of the mounting hole 102-3 and the outer peripheral surface of the first portion 103-1 may be provided in a regular octagon or a regular hexadecimal shape whose dimensions match.

In the present embodiment, when the inner peripheral surface of the mounting hole 102-3 is provided as a regular octagon; correspondingly, the shape of the outer peripheral surface of the first portion 103-1 is also set to be a regular octagon. The handle 102 and the lock member 103 are lockable in four states between (including) a closed state and an open state. Among the four states, there are three states that the handle 102 is locked and opened, and the included angles between the two handles (the first handle and the second handle) are: 90 degrees, 180 degrees, and 270 degrees.

Specifically, please refer to fig. 6 to 9, which are first to fourth structural diagrams of the handle when the outer peripheral surface of the first portion of the first embodiment is in a regular octagon shape, respectively. Specifically, fig. 6 shows a first perspective view of the handle at an angle of 90 degrees between the first handle and the second handle, and fig. 7 shows a second perspective view of the handle at an angle of 90 degrees between the first handle and the second handle. As can be seen from fig. 6 and 7: when the angle between the first handle 102-1 and the second handle 102-2 is 90 degrees, the lock member 103 can be used to lock the first handle 102-1 and the second handle 102-2 in that particular position.

Fig. 8 shows a schematic plan view of the handle at a 90 degree angle between the first handle and the second handle, and fig. 9 shows a schematic plan view of the handle at a 180 degree angle between the first handle and the second handle. As can be seen from fig. 9: the lock member 103 can be used to lock the first handle 102-1 and the second handle 102-2 in that particular position when the angle between the first handle 102-1 and the second handle 102-2 is 180 degrees.

In the present embodiment, when the inner peripheral surface of the mounting hole 102-3 is provided as a regular hexadecimal shape; correspondingly, the outer peripheral surface of the first portion 103-1 is also shaped like a regular hexadecimal. The handle 102 and the lock member 103 are lockable in eight states between (including) a closed state and an open state. Among the eight states, there are seven states that can be the state that the handle 102 is locked by opening, and the included angles between the two handles (the first handle and the second handle) in these seven states are: 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees.

Meanwhile, a guiding reminder 103-4 is added to a specific position of the handle, for example, the outer end face of the push-pull member 103-3, and as can be seen in fig. 8 and 9 in particular, the guiding reminder 103-4 is used to prompt the user to lock the first handle 102-1 and the second handle 102-2 by the lock element 103 when the first handle 102-1 and the second handle 102-2 of the handle 102 are rotated to the specific position. The particular positions correspond to angles that just lock the first handle 102-1 to the second handle 102-2. Specifically, the guiding and reminding mechanism 103-4 may be a plurality of marks on the outer end surface of the push-pull member 103-3 corresponding to a plurality of rotation angles of the first handle 102-1 and the second handle 102-2, and when the first handle 102-1 and the second handle 102-2 are rotated to be aligned with the marks, the user can select to lock the handles at the angles corresponding to the marks. More specifically, a mark on the outer end face of the push-pull member 103-3 corresponds one-to-one to an angle on the outer peripheral surface of the first portion 103-1 that can be used to lock the first handle 102-1 and the second handle 102-2.

In this embodiment, in order to facilitate the user to sense which angle the first handle 102-1 and the second handle 102-2 of the rotating handle 102 rotate to, the first handle 102-1 and the second handle 102-2 can be locked, specifically, a gear can be arranged inside the handle, and the gear is meshed with the first handle 102-1 and the second handle 102-2 of the handle 102, so as to facilitate the synchronous and angular rotation of the first handle 102-1 and the second handle 102-2 when the lock member 103 is located at the unlocking position.

In this embodiment, the first handle 102-1 and the second handle 102-2 can extend in a vertical direction when the handle 102 is in the closed state, and the first handle 102-1 and the second handle 102-2 are attached together, for example: a closed state as shown in fig. 1; the first handle 102-1 and the second handle 102-2 can extend in a horizontal direction when the handles 102 are in an open position, for example: the open state as shown in fig. 2; of course, when the inner peripheral surface of the mounting hole 102-3 is formed in a shape corresponding to the outer peripheral surface of the first portion 103-1 to be a regular even number (the even number is equal to or greater than six) polygon, the first handle 102-1 and the second handle 102-2 can be locked at a plurality of opening angles.

The process of unlocking and locking the handle 102 by the lock member 103 as described above is described by way of example in which an axial member is provided on the lock member 103 and a mounting hole is provided on the handle 102 for the axial member to pass through. It will be appreciated that an axial member may also be provided on the handle 102 and a mounting slot for the axial member to pass through may be provided on the lock element 103 to complete the process of unlocking the lock element 103 and locking the handle 102. The axial part on the handle 102 is butted with the mounting slot to mount the handle 102 on the handle body 101. Specifically, the handle body 101 is provided with an installation position, and the axial component passes through the installation slot position and further extends into the installation position, so that the handle 102 is installed on the handle body 101.

As long as it is ensured that the lock element 103 can unlock and lock the handle 102, the handle 102 has a closed state, an open state and can be switched between the closed state and the open state.

In this embodiment, as shown in FIG. 5, a magnetic attraction device 102-4 can be disposed on the first handle 102-1 and the second handle 102-2. The magnetic attraction 102-4 is configured to provide a force to engage the first handle 102-1 and the second handle 102-2 when the lock member 103 is in the unlocked position, such that the first handle 102-1 and the second handle 102-2 are engaged to close the handles 102. For example, when the first handle 102-1 and the second handle 102-2 are in the open state as shown in FIG. 2, if the handle 102 is desired to be in the closed state as shown in FIG. 1, the first handle 102-1 and the second handle 102-2 can be engaged together when the lock member 103 is in the unlocked position, and the magnetic attraction 102-4 maintains the handle 102 in the closed state. This avoids the extra action of manually engaging the first handle 102-1 and the second handle 102-2 together when the user operates the handle body 101 with one hand.

In this embodiment, a spring arrangement may also be provided between the first handle 102-1 and the second handle 102-2. The spring means is used to provide a force to separate the first handle 102-1 and the second handle 102-1 from each other when the lock member 103 is in the unlocked position, so that the handles 102 are in an open state. For example, if it is desired to place the handle 102 in the open state as shown in FIG. 2 when the first and second handles 102-1 and 102-2 are in the closed state as shown in FIG. 1, a spring device may be provided between the first and second handles 102-1 and 102-2, specifically a torsion spring provided at the junction of the first and second handles 102-1 and 102-2, and the torsion spring may be provided between the first and second handles 102-1 and 102-2, so that when the lock member 103 is in the unlocked position, the first and second handles 102-1 and 102-2 can be sprung open by the torsion spring, so that the handles 102 are in the open state. This avoids the user's manual operation of separating the first handle 102-1 from the second handle 102-2; of course, the spring means should be configured to be flexible enough to allow the first handle 102-1 and the second handle 102-2 to return to the closed position under the action of an external force.

In this embodiment, the installation position provided on the grip body 101 may refer to a relevant portion of the combination portion of the installation hole to receive the knob 102, and a hole of the axial member in which a structure to seat the first portion 103-1 of the axial member is provided, and a space of the structure to receive the first portion 103-1 of the axial member when the push-pull member 103-3 is pressed.

In the embodiment, as the handle on the handle body is matched with the lock element, when the lock element is positioned at the locking position, the handle can be locked at the current state, and when the lock element is positioned at the unlocking position, the handle can be switched between the closed state and the open state and further rotated to the closed state or the open state; therefore, the user can set the handle to the closed state or the open state when the lock element is located at the unlocking position, and move the lock element to the locking position after the lock element is set to the locking position, so that the handle is maintained at the closed state or the open state, and the user can conveniently hold the handheld cleaning device according to the needed mode.
