Fig. 1 and 2 show views of different perspectives of a handheld electrical device 1 according to an embodiment of the present disclosure. As shown in fig. 1 and 2, the hand-held electric device 1 includes a handle housing 10 and includes a main body function portion 20. The handle housing 10 forms part of the housing of the hand-held electrical device 1, the handle housing 10 being accessible for a user to grasp the electrical device. The main body function portion 20 is a function portion of the electrical device. The body function part 20 may be disposed above the handle housing 10 and have a size larger than that of the handle housing. In the illustrated embodiment, the electrical device 1 is shown as a blower; the main body function part 20 is an air intake and supply function part of the blower accordingly. It should be understood that the illustrated electrical device 1 is merely exemplary and that the inventive concepts according to the present disclosure are applicable to other electrical devices having handles, such as flashlights and the like.

In order to facilitate the handling of the electrical device 1 by a user, the handle housing 10 is typically formed in a shape suitable for the user to grasp, so that the user can conveniently hold the device and move the device portably. In the illustrated embodiment, the handle housing 10 is formed in the shape of a cylinder. It should be understood that the illustrated embodiment is merely exemplary, and that the handle housing 10 may be formed in any other ergonomic shape. The handle housing 10 is also provided with a switch assembly. The switch assembly may include an electrical portion of the switch and a manipulation portion of the switch. The manipulation portion of the switch is provided outside the handle housing 10 so that a user can manipulate the switch outside the handle housing 10.

As shown in fig. 1 and 2, the handle housing 10 is provided with a switch through hole 12. The mechanical switch 30 is mounted in the interior cavity of the handle housing 10. In the illustrated embodiment, the mechanical switch 30 is shown as a sliding switch and may include movable contacts. As the mechanical switch 30 moves within the internal cavity, the contacts may contact or separate from stationary contacts in the electrical circuit of the electrical device to effect opening and breaking of the electrical circuit. It should be understood that the illustrated mechanical switch 30 is merely exemplary and that the switch provided on the handle housing 10 may be any other suitable switch. Furthermore, although in the illustrated embodiment, the mechanical switch 30 is shown as a switch that switches the switch state; it should be appreciated that this is merely exemplary and that a mechanical switch may be used for switching between a plurality of different modes of operation. As an example, in the case where the electrical device is a blower, the mechanical switch may also be used as a speed gear switch of the blower.

In some embodiments, the mechanical switch 30 may include an integrally disposed switch member 32. The operation piece 50 is disposed at the switch through hole 12 and is operable by a user outside the handle housing 10. Inside the interior cavity, the operating member 50 is engaged with the switch member 32. Thus, the user can actuate the movement of the control 50 by applying a force to the control 50 exposed outside the handle housing 10. Since the operation member 50 is coupled to the switching member 32, the switching member 32 moves together as the operation member 50 moves, thereby switching the operation state of the mechanical switch 30. It should be appreciated that the illustrated switch member 32 is merely exemplary, and that the manipulation member 50 may be engaged with any other suitable portion of the mechanical switch 30.

According to an embodiment of the present disclosure, at least a portion of the manipulation member 50 is exposed to the outside of the handle housing 10, for example, through the switch through hole 12; at least a portion of the control member 50 is mounted directly with the mechanical switch 30 (e.g., switch member 32) within the handle housing 10. This has advantages in terms of installation of the control 50.

Such a control 50 structure permits the control 50 to be assembled with the mechanical switch 30 from outside the handle housing 10. By way of example, in some embodiments, the handle housing 10 is an integrally molded injection molded piece. In this case, the handle housing 10 is not detachable, and the permission manipulation piece 50 can be assembled with the mechanical switch 30 from the outside of the handle housing 10 in a case where the mechanical switch 30 is assembled to be arranged inside the handle housing. Further, considering that the manipulation member 50 can be assembled with the mechanical switch 30 from the outside of the handle housing 10, the size of the opening through hole 12 can be reduced, improving the overall appearance of the handle housing.

In some embodiments, the control 50 is a sliding control and is configured to slide along a straight line within the switch through hole 12. It should be understood that the illustrated embodiments are exemplary only; the control member 50 may select other types of switches according to the type of the mechanical switch 30, for example, in the case that the mechanical switch is a rotary switch, the control member 50 may be configured as a knob member. In the case where the mechanical switch is a push switch, the manipulation member 50 may be a manipulation button.

In some embodiments, the switch through hole 12 is an elongated hole that includes a first longitudinal end and an opposite second longitudinal end, wherein the control member 50 moves linearly between the first and second longitudinal ends. In some embodiments, the elongated aperture may also serve as a stop in addition to the guide operator control 50. In some embodiments, instead of an elongated aperture as a limiting action, the mechanical switch itself may be provided with a limiting member. It should be understood that the illustrated embodiments are merely exemplary and that the switch via may be implemented in any other suitable shape.

In some embodiments, as shown in fig. 1 and 2, at least a portion of the control 50 may extend beyond the outer surface of the handle housing 10. This is particularly advantageous when the mechanical switch is a sliding mechanical switch. This allows the user to conveniently apply the pushing force to the manipulation member 50.

In some embodiments, as shown in fig. 1 and 2, a cover plate 40 is also provided at the switch through hole 12. The cover plate 40 is configured to cover the switch through hole 12. The cover 40 is engageable with the manipulation member 50 and moves with the manipulation member 50 when the manipulation member 50 moves.

In some embodiments (not shown), the cover 40 is disposed on the exterior of the handle housing 10 and engages the handle 50 on the exterior of the handle housing 10. In some embodiments, as shown in fig. 1 and 2, the cover 40 is disposed inside the handle housing 10 and engages the manipulation member 50 inside the handle housing 10. In some embodiments, the cover 40 may include a cover through hole 42, and the control 50 is configured to pass through the cover through hole 42 to engage with the mechanical switch 30. By shielding of the cover plate 40, the electric devices disposed in the inner cavity can be prevented from being exposed through the switch through hole 12, and also foreign pollutants such as dust can be prevented from entering the inner cavity of the handle housing 10 through the switch through hole 12.

Fig. 3 and 4 show structural details of a switch assembly according to an embodiment of the present disclosure. As shown in fig. 3 and 4, the switch assembly may include: an operation piece 50 adapted to be exposed at the switch through hole 12 of the handle housing 10; a cover plate 40 arranged to remain covering the switch through hole 12 during movement of the manipulation member 50; and a mechanical switch 30 housed inside the handle housing 10 and adapted to be directly engaged with the manipulation member 50. Thus, when the user manipulates the manipulation control 50 outside the handle housing 10, the mechanical switch 30 moves along with it, thereby switching the operation state of the mechanical switch 30. Meanwhile, since the cover plate 40 remains covering the switch through hole 12 regardless of the operating state of the operating piece 50.

In some embodiments, as shown in fig. 3 and 4, the handle 50 includes a head section 54 and an engagement section 56 located on the inside of the cover 40. The outer peripheral dimension of the head section 54 is greater than the diameter of the cover through hole 42, and the outer peripheral dimension of the engagement section 56 is less than the diameter of the cover through hole 42 to permit the mounting of the control 50 to the mechanical switch 30 from the outside of the handle housing 10.

In some embodiments, as shown in fig. 3 and 4, the switch member 32 of the mechanical switch 30 is provided in the shape of a protrusion. The control 50 may include a shape adapted to engage the switch member 32. For example, the manipulation member 50 may include one or more claws 52 as engagement portions, the claws 52 being configured to be detachably locked with the switch member 32. It should be understood that in the illustrated embodiment, the switch 32 may be provided with a card slot, by way of example only. The engagement portion of the control member 50 may be provided in other suitable forms as long as locking of the control member 50 and the mechanical switch 30 can be achieved.

In some embodiments, the handle 50 may be coupled with the cover 40. In some embodiments, the handle 50 may be secured to the cover 40 by a snap, interference fit, rivet, hot melt or ultrasonic weld, or the like. As an example, the manipulation member 50 may be joined to the cover plate 40 at the head section 54. In other embodiments, the handle 50 may be joined to the cover 40 at a joining section 56. In other embodiments, the handle 50 may be joined to the cover 40 at a transition region between the head section 54 and the joining section 56. Fig. 5 and 6 respectively show partial cross-sectional views of a handheld electrical device according to an embodiment of the present disclosure. As shown in fig. 5 and 6, the cover plate 40 is disposed in the inner cavity, and the size of the cover plate 40 is set to be larger than the size of the switch through hole 12. Since the cover plate 40 is larger in size than the switch through hole 12, the cover of the cover plate 40 to the switch through hole 12 can be ensured. Considering that the cover 40 is larger in size than the switch through hole 12, it cannot be installed from the outside of the handle housing 10 as an integral member. According to the present disclosure, by allowing the operation piece 50 to be mounted with the mechanical switch 30 through the cover plate 40, which enables the cover plate 40 to be mounted inside the handle housing 10 without being exposed to the outside of the handle housing, the aesthetic appearance of the electrical device can be further improved.

In some embodiments, as shown in fig. 5 and 6, the electrical device 1 may further include a support bracket 34. The support bracket 34 may be configured inside the handle housing 10 and configured to support various functional components inside the handle housing. As an example, the support bracket 34 may be implemented as part of an internal functional device of the electrical apparatus. In some embodiments, the support shelf 34 may include a receiving slot 36 configured to receive a cover 40. The above-described construction of the support bracket 34 has advantages in terms of assembly. This allows the assembly of the cover 40 and the support bracket 34 to be installed together into the interior cavity of the handle housing 10 after the cover 40 and the support bracket 34 are assembled together. In addition, the receiving groove 36 may provide a track for movement of the cover 40. After the assembly of cover 40 and support bracket 34 is installed together into the interior cavity of handle housing 10, actuating member 50 is inserted into switch throughbore 12 outside of handle housing 10 such that actuating member 50 engages (e.g., snaps) with mechanical switch 30. During movement of the operating member 50, the receiving groove 36 guides movement of the cover plate 40.

With the control member 50, cover 40 and mechanical switch 30 in place, the user can actuate movement of the mechanical switch 30 by moving the control member 50. In the first state as shown in fig. 5, the operation piece 50 is located at the right side end of the switch through hole 12. Meanwhile, a cover plate 40 (shown as a hatched portion) covers the switch through hole 12 to maintain the closure of the inside of the handle housing.

When the user moves the operation member 50 leftward from the state shown in fig. 5, the operation member 50 moves toward the left longitudinal end in the opening through hole 12, and brings the mechanical switch 30 and the cover plate 20 together to move leftward. As shown in fig. 6, in a state where the manipulation member 50 abuts against the left longitudinal end, the mechanical switch 30 is switched from the first operation state to the second operation state. At the same time, the cover plate 20 remains covering the switch through hole 12 to maintain the closure of the interior of the handle housing. Thus, the cover plate 20 can always ensure the closure of the interior of the handle housing, regardless of the position of the operating member 50.

In the illustrated embodiment, the mechanical switch 30 is shown in two operating states. The two operating states may correspond to, for example, ON and OFF states of the device. It should be understood that this is merely exemplary and that mechanical switch 30 may include more than two operating states. As an example, the mechanical switch may include an operation state corresponding to a different gear in addition to the switch state.

Moreover, although operations are depicted in a particular order, this should be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing may be advantageous. Likewise, while several specific implementation details are included in the above discussion, these should not be construed as limiting the scope of the present disclosure. Certain features that are described in the context of separate embodiments can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombination.
