Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention.
Referring to fig. 1 and 2, a handheld power tool according to an embodiment of the present application includes: a main body 11; the main body 11 is provided with a first interface 16 and a second interface 18; a first power supply; for connection to the first interface 16 to enable power to be supplied to the hand-held power tool; a second power supply 15; for connection to the second interface 18 to enable power to be supplied to the hand-held power tool; a bypass structure 19 having a first state and a second state, the bypass structure 19 allowing the first power source to access the first interface 16 and preventing the second power source 15 from accessing the second interface 18 in the first state; in the second state, the bypass structure 19 allows the second power source 15 to access the second interface 18 and prevents the first power source from accessing the first interface 16.
The technical scheme shows that: in the electric hand tool according to the embodiment of the present invention, the avoidance structure 19 is provided, and the avoidance structure 19 has a first state and a second state, so that when the first power supply is connected to the first interface 16, the second power supply 15 can be prevented from being connected to the second interface 18 through the first state. And by this second state, to prevent the first power supply from accessing the first interface 16 when the second power supply 15 accesses the second interface 18. This prevents the main body 11 from simultaneously turning on both the first power supply and the second power supply 15.
In the present embodiment, the hand-held power tool according to the embodiment of the present invention may be a hair dryer, for example. Of course, the hand-held power tool is not limited to the hair dryer, and may be other tools, such as a lawn mower, and the like, and the application is not limited thereto.
In the present embodiment, the main body 11 includes a housing 29, and in the present embodiment, the housing 29 is a blower housing in which a flow passage for passing an air flow is formed. Further, a fan for generating a negative pressure is provided in the main body 11. So that the gas outside the main body 11 can enter the flow channel under the action of negative pressure and form a gas flow. Further, a motor for driving the fan to rotate is disposed in the main body 11. Of course, the main body 11 is not limited to a fan and a motor, and other devices may be provided, which is not limited in this application.
Further, the main body 11 is provided with a first port 16 and a second port 18. Specifically, the first and second interfaces 16, 18 are disposed on the blower housing, as shown, for example, in fig. 1.
In this embodiment, a first power source is used to connect to the first interface 16 to provide power to the hand held power tool. So that the first power supply can supply power to the main body 11 when the first power supply is connected to the first interface 16. Specifically, the first power source is used to supply power to a motor inside the main body 11, for example. Of course, the first power source is not limited to supplying power to the motor, and may also supply power to other devices, and the present application does not provide for this. Further, the first power source may be a battery pack. For example, the first power source is a battery pack with a power supply voltage of 20V. Of course, the power supply of the first power supply is not limited to 20V, and may be other voltage, for example, 25V, which is not specified in this application.
Further, the first interface 16 may be a general battery pack dedicated interface for connecting a general battery pack.
In particular, the first interface 16 has a first access terminal 46. The first access terminal 46 is adapted to be connected to a first power source. So that when the first access terminal 46 is connected to the first power source, the current in the first power source can flow into the main body 11 through the first access terminal 46, thereby supplying power to the hand-held power tool.
More specifically, the first port 16 may be provided with a hollow mounting chamber 33. The mounting chamber 33 is used for mounting a first power source. A battery holder for fixing the first power source is provided in the mounting chamber 33. The first access terminal 46 includes a positive terminal and a negative terminal disposed within the mounting chamber 33. The positive terminal is used for connecting the positive pole of the first power supply. The negative terminal is used for connecting the negative pole of the first power supply.
Further, the mounting chamber 33 is open toward one side of the housing 29. Specifically, as shown in fig. 1, the mounting chamber 33 has an open mouth 31 opened outward. So that the first power source can be put into the installation chamber 33 through the opening 31. Further, a slide rail is installed in the opening 31. The first power source can be moved along the slide rail to enter the mounting chamber 33.
Further, the first interface 16 is arranged inside the housing 29. The positive and negative terminals in the first port 16 can thus be protected by the housing 29 to prevent the positive and negative terminals from being damaged by external devices. Of course, the first interface 16 is not limited to be disposed inside the housing 29, and the first interface 16 may be disposed outside the housing 29, which is not limited in this application.
In this embodiment, the second power source 15 is adapted to be connected to the second interface 18 to enable power to be supplied to the hand-held power tool. So that the second power supply 15 can supply power to the main body 11 when the second power supply 15 is connected to the second interface 18. Specifically, the second power supply 15 is used to supply power to a motor inside the main body 11, for example. Of course, the second power source 15 is not limited to supplying power to the motor, and may supply power to other devices, and the present application does not provide for this. Further, the second power source 15 may be a backpack type power source, including a backpack or a waist pack, and a battery pack mounted on the backpack or the waist pack. The second power supply 15 is, for example, a backpack power supply having a power supply voltage of 80V. Of course, the power supply of the second power supply 15 is not limited to 80V, and may be other voltage, for example, 60V, which is not limited in this application. However, the voltage of the second power supply is higher than that of the first power supply, so that different requirements of the main body 11 for the power supply voltage can be satisfied by the first power supply and the second power supply 15.
Further, the second interface 18 may be a dedicated cable interface for a backpack power supply, and is used for connecting the backpack power supply.
Further, the second interface 18 has a second access terminal 48. The second access terminal 48 is for connection to a second power supply 15. So that when the second access terminal 48 is connected to the second power source 15, the current in the second power source 15 can flow into the main body 11 through the second access terminal 48 to supply power to the main body 11.
Further, as shown in fig. 1, the first access terminal 46 and the second access terminal 48 extend toward the same side of the housing 29. Thereby enabling access to the first and second power sources 15 on the same side of the housing 29. So that the escape structure 19 can extend towards the first interface 16 when the second power supply 15 is switched in the second interface 18, so that a stop can be formed for the first interface 16 in the mounting direction. This prevents the first and second access terminals 46, 48 from extending toward the two sides of the housing 29, and the relief structure 19 does not easily form a stop for the first port 16.
Further, the extending direction of the first access terminal 46 may coincide with the extending direction of the second access terminal 48, so that the accessing direction of the first interface 16 coincides with the accessing direction of the second interface 18. Of course, the extending direction of the first access terminal 46 may not coincide with the extending direction of the second access terminal 48. This application is not intended to be limited thereto.
Specifically, the connection direction of the first interface 16 is the connection direction of the first power supply to the first interface 16. Specifically, the first power supply is installed in the installation chamber 33 through the opening 31. Thus, the direction of the first power source connected to the first interface 16 is the moving direction of the first power source in the opening 31. For example, as shown in fig. 1, the opening 31 of the first port 16 opens toward the left side of the housing 29. The moving direction of the first power supply within the opening 31 is a left-right direction. The access direction of the first interface 16 is thus the left-right direction.
The connection direction of the second interface 18 is the connection direction of the second power supply 15 to the second interface 18. Specifically, the second power supply 15 is connected to the second interface 18 by contacting the receptacle 44 thereon with the ferrule of the second interface 18. The direction of the second power supply 15 accessing the second interface 18 is thus the extension direction of the ferrule. For example, as shown in fig. 1, the ferrule of the second port 18 extends in the left-right direction. Therefore, the direction of the second power supply 15 connected to the second interface 18 is the left-right direction.
More specifically, the second interface 18 may be a four-wire or five-wire cable receptacle for mating with a backpack battery plug. More specifically, referring to fig. 1, the second interface 18 is a cable socket as shown in fig. 1. The cable socket is capable of connecting a backpack battery having a cable plug 47 as shown in fig. 1. Further, the cable plug 47 is circular. The cable plug 47 includes a threaded cap 41, a receptacle 44 disposed within the threaded cap 41. The cable socket to which the cable plug 47 is mated has a second access terminal 48. The second access terminal 48 includes: for mating with the ferrule of the receptacle 44. When the cable plug 47 is inserted into the cable socket, the ferrule is in contact with the insertion hole 44, and the current of the backpack type battery flows into the body 11 through the ferrule, thereby supplying power to the body 11.
Further, the second interface 18 is located at one side of the housing 29. For example, as shown in fig. 1, the second port 18 is located on the left side of the housing 29.
Further, the second port 18 is located on the same side of the housing 29 as the opening 31 of the first port 16. For example, as shown in fig. 1, the second port 18 and the opening 31 of the first port 16 are located on the left side of the housing 29. Specifically, the ferrule of the cable receptacle extends toward the side of the housing 29 where the opening 31 of the first interface 16 is located. Thereby allowing the first and second power sources 15 to be accessed into the housing 29 from the same side of the housing 29.
Further, the second interface 18 is arranged inside the housing 29. The ferrule in the second port 18 can be protected by the housing 29 to prevent the ferrule from being damaged by external equipment. Of course, the second port 18 is not limited to be disposed inside the housing 29, and the second port 18 may be disposed outside the housing 29, which is not limited in this application.
Further, the first access terminal 46 and the second access terminal 48 are offset in a direction perpendicular to the extension direction of the first access terminal 46 and/or the second access terminal 48. The first access terminal 46 and the second access terminal 48 are offset from each other, that is, the first port 16 and the second port 18 are juxtaposed in the left-right direction.
In the present embodiment, the avoidance structure 19 has a first state and a second state. In the first state, the avoidance mechanism allows the first power source to access the first interface 16 and prevents the second power source 15 from accessing the second interface 18. Thereby ensuring that the first power supply and the second power supply 15 cannot be simultaneously connected to the first interface 16 and the second interface 18, respectively. In the second state, the avoidance mechanism allows the second power source 15 to access the second interface 1816 and prevents the first power source 15 from accessing the first interface 16. Thereby ensuring that the first power supply and the second power supply 15 cannot be simultaneously connected to the first interface 16 and the second interface 18, respectively. Thus, the first and second states of the bypass structure 19 prevent the main body 11 from being powered by both the first and second power sources 15.
In one embodiment, the bypass structure 19 is disposed on one of the first power source, the second power source 15, and the main body 11. In particular, the avoidance structure 19 may be configured on the first power source. Alternatively, the evacuation structure 19 may be disposed on the second power supply 15. Alternatively, the escape structure 19 may be disposed on the main body 11. As shown in fig. 1, for example, the avoidance structure 19 is configured to be disposed on the second power source 15.
Specifically, the bypass structure 19 may be secured to one of the first power source, the second power source 15, and the main body 11. The fixing mode can be screw fixing, bolt fixing, welding fixing, integral forming fixing and the like, and the application is not specified. Therefore, the avoiding structure 19 is fixed on one of the first power supply, the second power supply 15 and the main body 11, so that the avoiding structure 19 and one of the first power supply, the second power supply 15 and the main body 11 form a whole, the steps of mounting and dismounting the avoiding structure 19 are reduced, and the operation is simplified.
In one embodiment, the first and second power sources 15 are connectable in the same direction to the first and second interfaces 16 and 18, respectively. The escape structure 19 comprises a connecting portion 26 and a blocking portion 28. The connecting portion 26 is configured to be connected to the first power source or the second power source 15, and the blocking portion 28 is configured to switch the avoidance structure between the first state and the second state.
In a specific embodiment, the connecting portion 26 is connected to the second power supply 15, in the first state, after the first power supply is connected to the first interface 16, when the second power supply 15 is installed toward the second interface along the installation direction, the stopping portion 28 can abut against the first power supply, so as to prevent the second power supply from being continuously installed toward the second interface, and thus a first avoidance space for limiting the second power supply 15 from being connected to the second interface 18 is formed between the stopping portion 28 and the main body 11 in cooperation with the first power supply; in the second state, the stopping portion 28 can cover at least a portion of the first interface 16 along the installation direction of the first interface 16 after the second power supply 15 is connected to the second interface 18, so as to prevent the first power supply from being connected to the first interface 16 along the installation direction.
More specifically, as shown in fig. 1 for example, when the connection portion 26 is connected to the cable plug 47 of the second power source 15, the avoidance structure 19 can move with the cable plug 47 of the second power source 15. The first power supply is connected to the first interface 16 without being limited by the stop 28, and is in the first state. When the first power supply is connected to the first interface 16, a part of the first power supply extends out of the mounting chamber 33 through the opening 31, and when the cable plug 47 of the second power supply 15 is moved towards the second interface 18, the avoiding structure 19 also moves towards the second interface 18, and when the stopping portion 28 abuts against the first power supply protruding out of the first interface 16, the first power supply can limit the second power supply 15 to continue moving towards the second interface 18, and a first avoiding space is enclosed among the first power supply, the first stopping surface 21 and the second interface 18. Due to the first escape space, the jack 44 in the cable plug 47 of the second power supply 15 cannot be further installed toward the second interface, so that the second power supply 15 cannot access the second interface 18. Thereby making the second power supply 15 inaccessible to the second interface 18 when the first power supply is accessed to the first interface 16.
Further, the second power supply 15 is connected to the second interface 18 in the second state. When the second power supply 15 is connected to the second interface 18, the stopping portion 28 extends radially outward from the cable plug 47 of the second power supply 15, and extends to face the first interface 16 and cover at least a part of the slide rail in the first interface 16 along the installation direction of the first interface 16. Thereby causing the first interface 16 to be at least partially obscured. Thereby preventing the first power supply from accessing the first interface 16.
Further, the escape structure 19 is not limited to be provided on the cable plug 47 of the second power supply 15, and may be provided on a connector. In particular, the connector is used to connect the cable plug 47 and the second interface 18, such that the cable plug 47 can be connected to the second interface 18 via the connector. So that the cable plug 47 can be connected to the second interface 18 via the connector when the format of the cable plug 47 is not adapted to the format of the second interface 18. The connection head may then be an adapter. Specifically, the connector has a first connection end and a second connection end. The first connection end is adapted to mate with a cable plug 47 of the second power source 15. The second connection is adapted to the second interface 18. So that the second power supply 15 can be connected to the second interface 18 through the first connection terminal and the second connection terminal.
In another specific embodiment, the connecting portion 26 is connected to the first power supply, and in the first state, the stopping portion 28 can cover at least a portion of the second interface 18 along the installation direction of the second interface 18 after the first power supply is connected to the first interface 16, so as to prevent the second power supply 15 from being connected to the second interface 18; in the second state, the stopper portion 28 can abut against the second power supply 15 when the first power supply is connected to the first interface 16 after the second power supply 15 is connected to the second interface 18, so that a second avoidance space for limiting the first power supply from being connected to the first interface 16 can be formed between the stopper portion and the main body 11.
More specifically, when the connecting portion 26 is disposed on the first power source, the avoiding structure 19 can move with the first power source. In the first state, the first power is not limited by the stopper 28 when being connected to the first interface 16. When the first power source 15 is connected to the first interface 16, the stopping portion 28 extends radially outward from the first power source 15 and extends to face the second interface 18 and cover at least a part of the second interface 18 along the mounting direction of the second interface. Thereby causing the second interface 1816 to be at least partially occluded. Thereby preventing the second power supply 15 from accessing the second interface 1816.
When the second power supply 15 is connected to the second interface 18, the second power supply 15 forms a protrusion outside the second interface 1816. So that when the first power source 15 moves towards the first interface 16, the avoidance structure 19 also moves towards the first interface 16. Since the stop 28 extends radially outward from the first power source 15, when the stop 28 abuts against the second power source 15 protruding out of the second interface 18, the second power source 15 will limit the first power source 15 from moving further toward the first interface 16. And a second clearance space is enclosed between the second power source 15, the first stop surface 21 and the first interface 16. Due to the presence of this second escape space, the second power supply 15 cannot access the second interface 18.
Further, the connecting portion 26 is a tube body that extends lengthwise and can be sleeved. As shown in fig. 1, the tube is sleeved on the cable plug 47 of the second power source 15.
