Detailed Description

As shown in fig. 1, the blower 100 can sweep fallen leaves on the floor when the battery pack 200 is mounted, thereby cleaning the floor, lawn, and the like.

As shown in fig. 1 to 3, the blower 100 includes: an air duct 11, a housing 12, a motor 13, a fan 14, and a battery pack 200.

The duct 11 is formed with a duct 11a around a central axis 101, the duct 11a is centered on the central axis 101, and both ends of the duct 11 are defined as an air inlet 111 and an air outlet 112, respectively. The blowing air flow enters the air duct 11 from the air inlet 111, and the air duct 11 guides the air flow to blow out from the air outlet 112 along the central axis 101, so as to blow towards the fallen leaves.

The housing 12 includes: a main body part 121, a handle part 122, and a battery pack coupling part 123. The body portion 121 surrounds at least a portion of the ductwork 11. The handle portion 122 is for holding by a user. The battery pack coupling portion 123 is used for mounting the battery pack 200, and the battery pack coupling portion 123 can guide the battery pack 200 to be inserted to the rear end of the handle portion 122 along the first straight line 102.

The main body 121 surrounds and forms a receiving cavity 121a, a part of the air duct 11 extends into the receiving cavity 121a of the main body 121, and the other part is located outside the main body 121. Thus, the air inlet 111 at the rear end of the air duct 11 is located in the accommodating cavity 121a, and the air outlet 112 at the front end of the air duct 11 is located outside the accommodating cavity 121 a. The distance between the intake port 111 and the exhaust port 112 is also 65 cm or more and 77 cm or less in the direction along the center axis 101. An airflow inlet 121b is also formed at the rear end of the body part 121. The airflow flows from the outside of the housing 12 into the accommodating cavity 121a through the airflow inlet 121b, then enters the air duct 11a through the air inlet 111, and finally flows out from the air outlet 112. The main body 121 is further connected to an air inlet net 15 at the airflow inlet 121b, and the air inlet net 15 allows the heat dissipation airflow to enter the accommodating cavity 121a and prevents leaves, stones and the like from entering the accommodating cavity 121 a. The air inlet net 15 is connected to the rear end of the main body portion 121 by screws. The grill 15 and the air inlet 111 are spaced apart from each other by a predetermined distance in the direction along the center axis 101. Further, in the direction along the central axis 101, the minimum distance between the air inlet net 15 and the air inlet 111 is 2 cm or more and 10 cm or less. The main body portion 121 is also arranged substantially symmetrically about a median plane S, which can improve the balance of the entire machine.

The handle portion 122 is connected to the upper side of the body portion 121. The handle portion 122 extends along the second straight line 103, the direction of the second straight line 103 extending from the handle portion 122 intersects the central axis 101 in an inclined manner, and the degree of the included angle formed by the inclined intersection of the second straight line 103 and the central axis 101 is greater than or equal to 8 degrees and less than or equal to 18 degrees, and further, the degree of the included angle formed by the inclined intersection of the second straight line 103 and the central axis 101 is greater than or equal to 10 degrees and less than or equal to 15 degrees. The handle portion 122 is angled to allow the user to more comfortably and easily operate the blower 100.

The battery pack coupling portion 123 is provided at one end of the handle portion 122, and the battery pack coupling portion 123 is provided at the rear end of the handle portion 122. As shown in fig. 6, an access terminal 123a is further provided at the battery pack coupling portion 123, and the access terminal 123a is used for electrically connecting with an output terminal on the battery pack 200, so that the battery pack 200 supplies power to the motor 13. Further, the pack coupling portion 123 is located at an upper side of the intake vent 111 so as not to affect an intake air amount of the intake vent 111.

In this embodiment, the projection of the battery pack combining portion 123 in the plane perpendicular to the central axis 101 is located outside the projection of the air inlet 111 in the plane, so that the position of the battery pack combining portion 123 is reasonably set, thereby on one hand, ensuring the air inlet amount at the air inlet 111 and improving the blowing efficiency of the blower 100, and on the other hand, setting the center of gravity of the whole blower is more reasonable, and improving the balance performance of the blower 100 operated by the user.

The direction of the first straight line 102 in which the battery pack 200 is mounted to the pack coupling portion 123 is parallel to or within the bisector S. The first straight line 102 intersects the central axis 101 obliquely, and an included angle formed by the intersection of the first straight line 102 and the central axis 101 is greater than or equal to 55 degrees and less than or equal to 70 degrees. The first straight line 102 also obliquely intersects with a second straight line 103 extending from the handle portion 122, and an included angle formed by the intersection of the first straight line 102 and the second straight line 103 is greater than or equal to 65 degrees and less than or equal to 80 degrees. Thus, when the user holds the handle part 122 with his hand, since the battery pack coupling part 123 is disposed at a proper position, the battery pack 200 coupled to the rear end of the handle part 122 does not interfere with the user's wrist or arm, so that the user can hold the handle part 122 in a comfortable posture, and the user does not feel fatigue even after operating the hair dryer 100 for a long time, thereby improving the working efficiency.

The fan 14 is attached to the motor 13 and can be rotated about a central axis 101 by the motor 13. When the fan 14 rotates, blowing air flow can be generated, and the blowing air flow enters the casing 12 from the air inlet net 15, enters the air duct 11a from the air inlet 111, and finally is blown out from the air outlet. The fan 14 and the motor 13 are both disposed in the air passage 11a formed by the air duct 11, and in the central axis direction, the fan 14 and the motor 13 are both disposed between the air inlet 111 and the air outlet 112, and the fan 14 is further disposed between the air inlet 111 and the motor 13.

As shown in fig. 4 and 5, the battery pack coupling portion 123 protrudes beyond the handle portion 122 in the direction of the first straight line 102 by a dimension L1 of 5.5 cm or less. In this way, the size of the battery pack 200 or the battery pack coupling portion 123 protruding from the grip portion 122 can be restricted, and the interference of the battery pack 200 or the battery pack coupling portion 123 with the wrist and the arm of the user can be further reduced, thereby improving the comfort of the operation.

In the present embodiment, when the battery pack 200 is mounted to the battery pack coupling portion 123, the projection of the battery pack 200 in the plane perpendicular to the central axis 101 is also located outside the projection of the intake vent 111 in the plane, and the battery pack 200 is also located on the upper side of the intake vent 111. Thereby further ensuring the air intake of the blower 100 and improving the blowing efficiency. Specifically, the nominal voltage of the battery pack 200 is 18V, and the capacity is 5 Ah. The maximum wind speed of the blowing air flow blown by the blower 100 is equal to or higher than 85MPH, and further, the maximum wind speed of the blowing air flow blown by the blower 100 is equal to or higher than 90 MPH.

As shown in fig. 5 and 6, the battery pack coupling part 123 has a coupling surface 123b extending in a first plane parallel to the first straight line 102. The coupling surface 123b is further concavely formed with a coupling groove 123c, and an access terminal 123a is disposed in the coupling groove 123 c. When the battery pack 200 is coupled to the pack coupling portion 123, the battery pack 200 has a coupling surface 201 coupled to the coupling surface 123b, the battery pack 200 is further partially inserted into the groove, and the coupling surface 201 and the coupling surface 123b are parallel to each other. The attachment surface 201 and the attachment surface 123b are both located on the upper side of the air inlet 111, and a projection of the attachment surface 201 and the attachment surface 123b in a plane perpendicular to the central axis is located outside a projection of the air inlet 111 in the plane. The attachment surface 201 and the bonding surface 123b are parallel to the first straight line 102, an included angle formed by the plane where the attachment surface 201 is located and the central axis 101 in an inclined intersection mode is larger than or equal to 55 degrees and smaller than or equal to 70 degrees, and an included angle formed by the plane where the bonding surface 123b is located and the central axis 101 in an inclined intersection mode is larger than or equal to 55 degrees and smaller than or equal to 70 degrees.

A circuit board assembly 16 is also provided in the accommodation chamber 121 a. As shown in fig. 7 and 8, the circuit board assembly 16 includes a first circuit board 161, a second circuit board 162, and a support box 163, the first circuit board 161 and the second circuit board 162 being arranged in parallel with each other, and the first circuit board 161 and the second circuit board 162 being mounted into the support box 163. Thus, the first circuit board 161, the second circuit board 162 and the supporting box 163 can be integrated, so that the installation is convenient, and the space occupied by the first circuit board in the accommodating cavity 121a can be greatly reduced. The first circuit board 161 and the second circuit board 162 are each provided with electronic components thereon. The first circuit board 161 is located at a lower side of the second circuit board 162, and the first circuit board 161 is also connected with a heat sink 164. In order to dissipate heat from the circuit board assembly 16, the front end of the housing 12 is surrounded by a through hole 124 through which the air duct 11 extends, and a gap 124a is formed between a wall of the through hole 124 and an outer wall of the air duct 11, the gap 124a allowing a heat dissipating airflow to enter the accommodating chamber 121a from the outside, and the gap 124a is located on the upper side of the air duct 11. The inner wall of the housing 12 is further provided with a guide portion 125, and the guide portion 125 guides the flow of the heat dissipating air flow. As shown in fig. 9 and 10, the guide portion 125 is provided with a diversion port 125a, and the diversion port 125a allows the heat dissipation airflow to pass through, so that a part of the heat dissipation airflow flows along the lower side of the guide portion 125, and a part of the heat dissipation airflow enters the upper side of the guide portion 125 through the diversion port 125a, thereby forming two paths of heat dissipation airflow in the accommodating cavity 121 a. One of the heat dissipation airflows flows through the lower side of the first circuit board 161, and the other airflow flows through the upper side of the second circuit board 162, so that the heat dissipation airflows can simultaneously dissipate the heat of the electronic components on the first circuit board 161 and the second circuit board 162. After flowing through the circuit board assembly 16, the heat dissipation airflow does not flow out of the housing 12 from the housing 12, but directly enters the air inlet 111 from a position between the air inlet net 15 and the air inlet 111, finally passes through the air duct 11 and flows out of the air outlet 112.

The first circuit board 161 and the second circuit board 162 are also located outside the handle portion 122, and the first circuit board 161 and the second circuit board 162 are also disposed between the handle portion 122 and the air duct 11.

In addition, the guide portion 125 is also formed of two portions, and includes a left guide portion 126c and a right guide portion 127c, respectively, the left guide portion 126c includes a first portion 126d and a second portion 126e, and the right guide portion 127c includes a third portion 127d and a fourth portion 127 e. When the left shell 126 and the right shell 127 are butted, the left guide portion 126c and the right guide portion 127c are butted, the edge of the first portion 126d is abutted with the edge of the third portion 127d, and the edge of the second portion 126e is spaced from the edge of the fourth portion 127e to form a diversion port 125a between the second portion 126e and the fourth portion 127 e.

As shown in fig. 9 to 11, at least one damping element 17, in particular a damping mat, is also arranged between the housing 12 and the wind pipe 11. The damper element 17 is disposed between the main body portion 121 of the housing 12 and the air duct 11. Motor 13 and fan 14 set up in wind channel 11a, will produce great vibration, and the vibration can be transmitted to tuber pipe 11, and the position that holds motor 13 and fan 14 of tuber pipe 11 sets up in main part 121 of casing 12 again, and like this, if do not have damping element 17, the vibration can be transmitted to main part 121 through tuber pipe 11, then transmits to handle portion 122 again, can make user's feeling tired like this, and can make user's not stable hair-dryer 100 of gripping, reduce work efficiency. And through the setting of damping element 17 for vibration is after transmitting tuber pipe 11, is absorbed by damping element 17 basically, thereby effectual reduction transmits to the vibration of main part 121, and then makes the stability of complete machine good, and the user can be light, laborsaving, stable grips hair-dryer 100, improves work efficiency.

As shown in fig. 12 to 14, a first mounting structure 113 for mounting the damping element 17 is formed on an outer surface of the air duct 11, and the damping element 17 is mounted to the first mounting structure 113.

The housing 12 includes: a left housing 126 and a right housing 127. The left housing 126 and the right housing 127 are connected by screws. The damping element 17 is also arranged on the mid-plane S. In this way, in the process of butting the left casing 126 and the right casing 127, the user can see the position of the vibration damping element 17, the position of the contact part of the left casing 126 and the vibration damping element 17, and the position of the contact part of the right casing 127 and the vibration damping element 17, so that the positions of the left casing 126 and the right casing 127 and the vibration damping element 17 can be relatively corresponded, and the user can accurately install the left casing 126 and the right casing 127. On the contrary, if the damping member 17 is not disposed on the middle section S, but disposed on the left or right side of the middle section S, then, when the user is to butt the left casing 126 and the right casing 127, the relative position of the left casing 126 and the damping member 17 and the relative position of the right casing 127 and the damping member 17 need to be considered, in fact, because the air duct 11 is disposed in the main body 121, the user cannot see the position of the damping member 17 when mounting the left casing 126 and the right casing 127, and thus only the left casing 126 and the right casing 127 can be mounted blindly, which increases the difficulty of mounting and also makes the mounting less accurate.

The number of damping elements 17 is four. The four damping elements 17 are arranged on the central section S of the housing 12, which facilitates the assembly. Wherein, two damping elements 17 set up the upside in tuber pipe 11, and two other damping elements 17 set up the downside in tuber pipe 11 for hair-dryer 100's stability is better, and the equilibrium is also better.

The body portion 121 is formed with a second mounting structure 128, the second mounting structure 128 and the first mounting structure 113 cooperating to fix the position of the damping element 17 within the housing 12. In this way, the damping element 17 can be connected to the air duct 11 and the housing 12, respectively, so as to reduce the vibration transmitted from the air duct 11 to the housing 12.

The left housing 126 has a left mounting structure 126a formed thereon and the right housing 127 has a right mounting structure 127a formed thereon. The left mounting structure 126a and the right mounting structure 127a together comprise a second mounting structure 128.

The damping element 17 is a cylinder centered on the center line 103 and centrally formed with a mounting hole 171 closed at one end and open at the other end. The first mounting structure 113 is a mounting post that mates with the mounting hole 171. The damping element 17 is mounted on the mounting posts such that the first mounting structure 113 limits the damping element 17 from disengaging from the air duct 11 in a radial direction perpendicular to the centre line 103.

The left mounting structure 126a is formed with a left groove 126b, the right mounting structure 127a is formed with a right groove 127b, the left groove 126b and the right groove 127b exhibit a circular arc shape, and the vibration damping element 17 is a circular pad. Thus, when the left and right housings 126 and 127 are mated, the left and right mounting structures 126a and 127a cooperate to mount the damping element 17 such that the damping element 17 is partially inserted into the left recess 126b and partially inserted into the right recess 127 b. Thus, the defect that the damping element 17 needs to be mounted blindly when being arranged at the left or right side of the bisecting plane S can be avoided, or if the damping element 17 is mounted only through the left housing 126 without being mounted by the right housing 127, the damping element 17 needs to be mounted blindly when the machine is mounted, which inevitably makes the mounting position inaccurate, causes shaking, and the like. When the damping element 17 is installed, the damping element 17 may be installed in the left groove 126b, the left groove 126b can install the damping element 17, so that the position of the damping element 17 is basically confirmed, and then the right housing 127 is abutted to the left housing 126, so that the damping element 17 is also installed by the right installation structure 127a, and thus the precise installation of the damping element 17 is completed.

The left mounting structure 126a is also formed with a first left arc 126f and a second left arc 126g, and the right mounting structure 127a is formed with a first right arc 127f and a second right arc 127 g. When the left and right cases 126 and 127 are butted, the first left circular arc 126f and the first right circular arc 127f are butted to form a first circle surrounding the cylinder in one circumferential direction around the center line 103, and the first right circular arc 126g and the second right circular arc 127g are butted to form a second circle located on the upper side of the cylinder. The radius of the first circle is larger than the radius of the second circle. The radius of the first circle is the same as the radius of the cylinder, and the radius of the second circle is smaller than the radius of the cylinder. The second mounting structure 128 thus prevents the damping element 17 from being detached from the first mounting structure 113 in the direction of the centre line 103.

As shown in fig. 14 to 16, the duct 11 includes: an air inlet pipe 114, an air outlet pipe 115 and a connecting pipe 116. The air inlet pipe 114, the connecting pipe 116 and the air outlet pipe 116 are arranged in sequence along the direction of the central axis 101. A connection pipe 116 is provided between the inlet duct 114 and the outlet duct 115 and connects both of them. The end of the air inlet pipe 114 away from the connecting pipe 116 forms an air inlet 111, and the end of the air outlet pipe 115 away from the connecting pipe forms an air outlet 112. The connecting pipe 116 is detachably connected with the air inlet pipe 114, and the connecting pipe 116 is detachably connected with the air outlet pipe 115. Blower 100 also includes a motor housing 18 and a deflector 19. The motor accommodating portion 18 is used for accommodating the motor 13, and the motor accommodating portion 18 is fixedly connected with the air inlet pipe 114. The guiding portion 19 is used for guiding the airflow, the guiding portion 19 is disposed between the motor accommodating portion 18 and the air outlet 112, and the guiding portion 19 is fixedly connected to the connecting pipe 116.

Two damping elements 17 are provided between the air inlet duct 114 and the main body portion 121, and two damping elements 17 are provided between the connection duct 116 and the main body portion 121. The vibration generated by the motor 13 and the fan 14 is transmitted to the air inlet pipe 114 through the motor accommodating portion 18, and the vibration generated by the motor 13 and the fan 14 is transmitted to the connecting pipe 116 through the diversion portion 19, and the air inlet pipe 114 is provided with the vibration damping element 17, and the connecting pipe 116 is also provided with the vibration damping element 17, so that the vibration transmitted to the housing 12 from the air inlet pipe 114 can be reduced, and the vibration transmitted to the housing 12 from the connecting pipe 116 can also be reduced.
