Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
As shown in fig. 1 and 2, the blower 100 includes: motor 10, fan 20, battery package 30, casing 40, handle 50 and dryer 60.
The motor 10 is used to drive the fan 20, rotating the fan 20 about a central axis 21 for generating an air flow. The battery pack 30 supplies power to the motor 10. The case 40 is formed with a fitting portion 41, and the battery pack 30 is detachably attached to the fitting portion 41. Handle 50 is held by a user to operate blower 100. Specifically, the handle 50 is formed by the housing 40. The handle 50 is provided with a control switch 51, and the user can control the control switch 51 when holding the handle 50. The centers of gravity of the handle 50 and the battery pack 30 are located on both sides of the central axis 21 of the fan 20, respectively. The air duct 60 is formed with an air duct 61, and the air duct 61 guides the air flow generated by the fan 20. The motor 10 and the fan 20 are located within the air duct 61. Specifically, the fan 20 is an axial fan, and the air passage 61 is a linear air passage.
As shown in fig. 2 and 3, the motor 10 includes a motor housing 11 and a winding 12. The windings 12 are accommodated in the motor housing 11. The motor 10 is provided with air inlet openings 13, and specifically, the air inlet openings 13 are formed by the motor housing 11. The air inlet holes 13 are used for allowing air flow to enter so as to cool the interior of the motor 10.
As shown in fig. 3, an air inlet 62 and an air outlet 63 are formed at both ends of the air duct 60; the fan 20 drives the air flow to enter the air duct 60 from the air inlet 62 and to be exhausted from the air outlet 63. The fan 20 is positioned between the intake vent 62 and the motor 10. The blower 100 further includes a support device 70, and the support device 70 supports the motor 10 in the air duct 61.
As shown in fig. 3 and 4, the supporting device 70 includes: a guide portion 71, a fixing portion 72, and a connecting portion 73.
The guide portion 71 is disposed between the motor 10 and the inner wall of the air duct 60. The guide part 71 can divert at least part of the airflow flowing along the air duct 61 and then flow to the motor 10; specifically, referring to the direction of the arrow in fig. 3, the guide portion 71 can divert at least a portion of the airflow flowing along the air duct 61 and then enter the interior of the motor housing 11 through the air inlet holes 13. The guiding function of the guiding portion 71 changes the flow direction of the partial air flow flowing along the air duct 61 so that the air flow entering the interior of the motor 10 is increased, and the cooling effect is improved.
The fixing part 72 is used for fixing the motor 10; the motor 10 is fixed to the fixing portion 72 by screws. The fixing portion 72 is formed with an airflow inlet 721. The fixing portion 72 forms an air inlet 721 corresponding to the air inlet 13 formed in the motor housing 11. The rotation of the fan 20 causes the air flow to pass through the fan 20, the guide portion 71 and the motor 10 in sequence. Part of the air flow generated by the rotation of the fan 20 enters the interior of the motor housing 11 through the air flow inlet 721 and the air inlet holes 13 by the action of the guide portion 71 to cool the motor 10.
The connecting portion 73 connects the guide portion 71 and the air duct 60. Specifically, the connecting portion 73 connects the fixing portion 72 and the air tube 60, thereby fixing the motor 10 at a specific position within the air duct 61. The number of the connecting portions 73 is 3 or more, and the number of the guide portions 71 is 3 or more. The number of the guide portions 71 corresponds to the number of the connecting portions 73. Specifically, as shown in fig. 4 and 5, the number of the connecting portions 73 is 3, and the plurality of connecting portions 73 are uniformly distributed along the central axis 21. More specifically, the number of the guide portions 71 is 3, and the plurality of guide portions 71 are distributed along the center axis 21.
As shown in fig. 6 and 7, the guide portion 71 is formed with a wind guide groove 711; specifically, the guide portion 71 includes: a first guide surface 712 and a second guide surface 713. The air guide groove 711 is formed by the first guide surface 712 and the second guide surface 713. The plane in which the first guide surface 712 is located obliquely intersects the central axis 21 of the fan 20. The plane in which the first guide surface 712 is located obliquely intersects the radial direction of the central axis 21 of the fan 20. Specifically, the first guide surface 712 and the second guide surface 713 are planar. One end of the air guide groove 711 close to the airflow inlet 721 is a near end of the air guide groove 711, and one end of the air guide groove 711 far away from the airflow inlet 721 is a far end of the air guide groove 711; the distance between the proximal end of the air guide groove 711 and the motor 10 in the direction of the central axis 21 of the fan 20 is smaller than the distance between the distal end of the air guide groove 711 and the motor 10. The first guide surface 712 and the second guide surface 713 are arranged or the air guide groove 711 is arranged in a direction such that the wind generated by the rotation of the fan 20 can be smoothly guided into the motor 10, thereby improving the cooling efficiency.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
