Disclosure of Invention

The invention discloses a branding accessory for a hot air blower, which comprises an embossing device for embossing a processing surface and a connecting device for connecting the embossing device with an air outlet of the hot air blower.

The invention provides a branding accessory, by which the use possibility of a hot air blower can be expanded. The stamp can be stamped, for example, on the work surface by means of a stamping attachment. The branding accessories can be heated by means of the heated air from the hot air blower.

The branding attachment is designed to be able to be connected to the hot air blower in a particularly releasable manner. The branding attachment may be configured to be insertable into an air outlet of a hot air blower. The branding attachment can be configured, for example, in the form of a can, in the form of a cap, in the form of a bowl or in the form of a sleeve. When the branding attachment is connected to the hot air blower, heated air may flow into, around, and/or through the branding attachment and heat the branding attachment. The branding attachment is made of a heatable material, which is substantially heat-resistant and heat-conducting. For example, the branding attachment is made of metal, such as brass.

The hot air blower is designed as an electrically operated hot air blower. The electrically operated hot air blower can be designed as a mains-operated hot air blower or as a battery-operated hot air blower. For example, the heat gun may be configured as a heat gun or a heat blower. Furthermore, the heat gun is also constructed as a hand-held heat gun. The air heater comprises a housing having an air outlet. The housing comprises an electric heating device and a fan wheel with an electric drive motor. The electric drive motor and the electric heating device can be controlled and/or regulated by means of a control unit. Furthermore, the heat blower may have a temperature sensor. The electric drive motor may drive the fan impeller. The electric heating device is configured for heating air. The heated air is output from the housing through the air outlet by means of the fan wheel.

The electric drive motor, the electric heating device and/or the control unit are configured to be actuated by a manual switch. If the manual switch is actuated by the user, the electric drive motor, the electric heating device and/or the control unit are switched on and the hot air blower starts to run. If the user accordingly no longer actuates the manual switch, the electric drive motor, the electric heating device and/or the control unit are switched off.

The heat gun comprises an energy supply device, wherein the energy supply device is provided for battery operation by means of a battery, in particular a battery pack of a handheld power tool, and/or for grid operation. In a preferred embodiment, the energy supply device is designed for battery operation. Within the scope of the present invention, a "hand-held power tool battery pack" is to be understood to mean a combination of at least one battery cell and a battery pack housing.

The hot air blower 100 is designed here, for example, as a battery hot air blower. The air heater 100 has a housing 110 with a handle 126 and an air outlet 112. For network-independent power supply, the heat blower 100 can be mechanically and electrically connected to a battery-operated power supply, so that the heat blower 100 is designed as a battery-operated heat blower 100. In this case, the battery pack 130 of the hand-held power tool serves as an energy supply device. However, the invention is not limited to battery-operated air blowers, but also air blowers which are grid-dependent, i.e. run on the grid, can be used.

The housing 110 of the air heater 100 comprises an electric heating means 120 and a fan impeller 119 with an electric drive motor 114. In addition, the heat blower 100 further includes a control unit 170. The drive motor 114 and the heating device 120 can be controlled and/or regulated using the control unit 170. The drive motor 114 drives the fan impeller 119. The heating device 120 heats air. The heated air is discharged from the housing 110 through the air outlet 112 as an air flow using the fan wheel 119. The air heater 100 includes a temperature sensor 172. The drive motor 114, the heating device 120 and the control unit 170 can be activated by means of the manual switch 128. When the manual switch 128 is manipulated by the user, the drive motor 114, the heating device 120 and the control unit 170 are turned on and the operation of the air heater 100 is started. When the user no longer manipulates the manual switch 128, the drive motor 114, the heating device 120, and the control unit 170 are turned off.

Furthermore, the housing 110 comprises a power supply device holding device 160. The energy supply device holder 160 receives the hand-held power tool battery pack 130 and forms a base 162 with a standing surface. The hand-held power tool battery pack 130 can be released from the energy supply device holder 160 without tools. In one embodiment, the energy supply device holder 160 is disposed on the handle 126. The air heater 100 may be shut down by the base 162.
