Definitions

  • the present disclosure relates to the technical field of household appliances, and in particular, to a hair dryer.
  • multiple cables are usually provided inside the hair dryer to electrically connect the components. Because of the limitation of the shapes and sizes of the cables, it is not possible to effectively reduce the volume of the handle. Meanwhile, the setting of multiple cables is not conducive for the user to assemble and disassemble the hair dryer, which reduces the usability of the hair dryer.
  • the main objective of the present disclosure is to provide a hair dryer, which aims to effectively reduce the volume of the hair dryer, so as to facilitate the user to hold it, and improve the operation during the installation and maintenance of the hair dryer, thereby improving the usability of the hair dryer.
  • a hair dryer including:
  • the power line includes a live wire terminal and a neutral wire terminal
  • the hair dryer includes: a first conductive metal sheet connected to the live wire terminal; and a second conductive metal sheet connected to the neutral wire terminal, the first conductive metal sheet and the second conductive metal sheet being symmetrically disposed on the inner wall of the housing.
  • the conductive metal sheet is integrated with the inner wall of the housing; and/or the conductive metal sheet is a copper sheet.
  • an anti-oxidation layer is formed on a portion of the conductive metal sheet exposed outside the inner wall of the housing.
  • the housing includes a body and a handle connected to the body; the conductive metal sheet is disposed on an inner wall of the handle; the main control board is disposed in the body; and the power line is connected to an end of the handle away from the body.
  • the hair dryer further includes an operation switch slidably disposed on the handle and located between the body and the conductive metal sheet, the operation switch being configured to make the main control board and the conductive metal sheet in a conducting state or a non-conducting state by sliding.
  • the handle includes an air inlet; the body includes an air outlet; and the hair dryer further includes a fan located in the handle and electrically connected to the main control board, the fan being configured to suck an external air fluid from the air inlet.
  • the hair dryer further includes: a first filter sleeve sleeved and fixed on the handle, and configured to cover the air inlet, the first filter sleeve including first filter holes for filtering the external air fluid.
  • an end of the handle away from the body is protruded with abutting protrusions, the abutting protrusions being configured to limit the first filter sleeve when the first filter sleeve is sleeved on the handle; and/or the hair dryer further includes a second filter sleeve connected to the end of the handle away from the body, an inner surface of the second filter sleeve being abutted against an outer surface of the first filter sleeve, the second filter sleeve including second filter holes oppositely disposed to the first filter holes, and a pore diameter of one of the first filter holes is smaller than a pore diameter of one of the second filter holes.
  • the present disclosure further provides a hair dryer, including:
  • the hair dryer includes a housing provided with a main control board; a power line connected to the housing and extending out of the housing; and a conductive metal sheet fixed to an inner wall of the housing, and configured to electrically conduct the main control board and the power line.
  • the conductive metal sheet is used to replace multiple cables to achieve electrical continuity, thereby saving the wiring space in the housing of the hair dryer, which can correspondingly reduce the size of the hair dryer and improve the user's feeling of holding the hair dryer.
  • the conductive metal sheet does not easily affect the maintenance operation of the user. Meanwhile, since the conductive metal sheet is fixed to the inner wall of the housing, the conductive metal sheet is not easy to shake when using the hair dryer, thereby improving the usability of the hair dryer.
  • fixed can be fixed connections, detachable connections, or integral connections; may also be mechanical or electrical connections; may also be direct connections or indirect connections via intervening structures, may also be inner connecting of two elements, or interaction relationship between two elements.
  • fixed can be fixed connections, detachable connections, or integral connections; may also be mechanical or electrical connections; may also be direct connections or indirect connections via intervening structures, may also be inner connecting of two elements, or interaction relationship between two elements.
  • the descriptions, such as the "first”, the “second” in the embodiment of present disclosure, can only be used for describing the aim of description, and cannot be understood as indicating or suggesting relative importance or impliedly indicating the number of the indicated technical feature. Therefore, the feature indicated by the “first”, the “second” can express or impliedly include at least one feature.
  • the meaning of "and/or” appearing throughout the text is that it includes three paratactic schemes, taking "A and/or B" as examples, including scheme A, or scheme B, or schemes that A and B meet at the same time.

  • an anti-oxidation layer is formed on a portion of the conductive metal sheet 30 exposed outside the inner wall surface of the housing 10. Since the conductive metal sheet 30 is exposed outside for a long time, it is prone to oxidation, resulting in a decrease in conductive performance. Therefore, the anti-oxidation layer is formed on a portion of the conductive metal sheet 30 exposed outside the inner wall surface of the housing 10, which not only effectively prevents the oxidation of the conductive metal sheet 30, but also increases the conductivity.

  • the operation switch 40 slides to the initial position, the operation switch 40 is separated from the conductive metal sheet 30 at this time, so that the body 11 and the conductive metal sheet 30 are disconnected to stop the work of the hair dryer 100.
  • the user can control the opening and closing of the hair dryer 100 by sliding the operation switch 40, which is more convenient.
  • the operation switch 40 is always abutted against the conductive metal sheet 30. By sliding the operation switch 40 to abut and disengage the operation switch 40 from the body 11, the body 11 may be connected and disconnected with the conductive metal sheet 30.

  • the conductive metal sheet 30 is provided instead of a plurality of cables to achieve electrical conduction, thereby saving the wiring space in the handle 12, reducing the size of the hair dryer 100, and improving the user's feeling when holding the handle 12 of the hair dryer 100.
  • the coincidence of the central axis of the fan with the central axis of the handle 12 can not only further reduce the size of the handle 12, but also in the process of using the hair dryer, when the fan speed exceeds 50,000 rpm, if the fan is not concentric with the handle 12, centrifugal force will be generated. Therefore, when the user uses the hair dryer, the user needs to apply more force to overcome the centrifugal force of the motor.
  • the central axis of the fan coincides with the central axis of the handle 1212, so the centrifugal force generated by the fan at high speed can be reduced to reduce the force required for the user to hold the hair dryer, which further optimizes the user's feel when holding the handle 12.
