Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Please refer to Figure 1 and Figure 2. The garden blowing device provided by an embodiment of the present application includes: a housing 11; it includes an air duct 18, and the air duct 18 includes an air inlet section and an air outlet section, wherein the air outlet section extends longitudinally; The airflow generating mechanism 19 is arranged in the air duct 18; the airflow generating mechanism 19 is used for generating airflow, and includes a fan 21 and a motor 23 for driving the fan 21 to rotate around a rotation axis; and the air inlet section and The air outlet sections are respectively located upstream and downstream of the air flow generating mechanism 19 in the flow direction of the air flow; the holding mechanism 26 includes a holding portion housing 28 and a support tube 29; one end of the support tube 29 is connected In the housing 11, the other end of the support tube 29 opposite to the housing 11 is connected to the holding portion housing 28, and the holding portion housing 28 is provided with a grip for the user to hold. The holding part; the holding part housing 28, the support tube 29, the air inlet section and the air outlet section are arranged in sequence in the direction of the rotation axis; the extension direction of the holding part and the direction of the rotation axis Consistent. The projection of the holding part on the rotation plane of the fan falls within the range of the projection of the air duct on the rotation plane. In this specific embodiment, the direction of the rotation axis of the fan is consistent with the longitudinal extension direction of the air outlet section.

When in use, the hand is held on the holding part, and the air flow is generated by the air flow generating mechanism 19, so that the air flow flows from the air inlet section to the air outlet section, and flows out from the air outlet section. This forms a blow.

It can be seen from the above technical solutions that the garden blowing device according to the embodiment of the application is provided with a housing 11, an air flow generating mechanism 19, and a holding mechanism 26, wherein the holding part housing 28, the supporting pipe 29, and the air inlet section And the air outlet sections are arranged in sequence in the longitudinal extension direction; and the extension direction of the grip part is consistent with the longitudinal extension direction; thereby effectively reducing the volume of the garden blowing device in the radial direction, making its radial direction It occupies the smallest volume. In turn, the occupied space is reduced, and the flexibility and convenience of operation are improved. Furthermore, the safety regulations of the garden hair dryer require that the distance between the grip portion held by the user and the air outlet 31 is greater than 700 mm. However, if the length of the air duct 18 is too long, the air outlet efficiency will be reduced. Therefore, when the length of the air duct 18 is optimal, the holding part housing 28 is placed behind, and the supporting tube 29 is used to support and extend the design requirement of 700 mm.

In this embodiment, as shown in FIG. 1, the housing 11 has a hollow rod shape as a whole. The hollow part forms a through channel 44. Of course, the housing 11 is not limited to a rod shape, but may also have other shapes; for example, a cube shape, which is not specified in this application. The housing 11 includes an air duct 18. The air duct 18 forms a through channel 44. Specifically, the air duct 18 includes an air inlet section and an air outlet section. The air outlet section extends longitudinally. As shown in Fig. 1, the air duct 18 extends in the vertical direction. The air pipe 18 is used for passing airflow, so that the air pipe 18 can blow outward.

Further, the casing 11 may include a casing 13, a blow pipe 15 and a siphon pipe 16 arranged in a longitudinally extending direction. The casing 13, the blow pipe 15, and the siphon pipe 16 are all hollow structures. In addition, the casing 13, the blow pipe 15 and the siphon pipe 16 communicate with each other to form a wind pipe 18. The inner diameter of the casing 13 is larger than the inner diameter of the blow pipe 15. Therefore, the air flow generating mechanism 19 can be installed in the casing 13. The inner diameter of the siphon tube 16 is larger than the inner diameter of the blow tube 15. Therefore, when the airflow in the air duct 18 flows from the blowpipe 15 to the siphon 16, the flow speed can be increased, which is beneficial for the airflow to flow out of the siphon 16.

In this embodiment, the air duct 18 has opposite ends in the longitudinally extending direction. For example, as shown in FIG. 1, the two ends are the upper end and the lower end of the air duct 18 respectively.

In this embodiment, the air flow generating mechanism 19 is provided in the air duct 18. Specifically, the air flow generating mechanism 19 may be fixedly arranged in the air duct 18. The fixing method may be screw fixing, bolt fixing, etc., which is not specified in this application.

Further, the air flow generating mechanism 19 can be provided in any part of the air duct 18. For example, the air flow generating mechanism 19 may be provided between the two ends of the air duct 18. The air flow generating mechanism 19 may also be arranged in either end of the two ends of the air duct 18. That is, the air flow generating mechanism 19 is arranged in the upper end of the air duct 18. Or the air flow generating mechanism 19 is provided in the lower end of the air duct 18.

Preferably, in order to enable the airflow generating mechanism 19 to form a stable airflow in the air duct 18, the airflow generating mechanism 19 is arranged in either end of the air duct 18. For example, as shown in FIG. 1, the air flow generating mechanism 19 is provided at the upper end of the air duct 18. Specifically, the cabinet 13 is located at the upper end. The air flow generating mechanism 19 is provided in the casing 13.

In this embodiment, the airflow generating mechanism 19 is used to generate airflow. The air inlet section and the air outlet section are respectively located upstream and downstream of the air flow generating mechanism 19 in the flow direction of the air flow. That is, the air flow generating mechanism 19 divides the air duct 18 into an air inlet section and an air outlet section. For example, as shown in Figure 1, the air inlet section is located above the air outlet section. Thus, the airflow can flow from the air inlet section to the air outlet section and out from the air outlet section. For example, as shown in FIG. 1, the airflow generating mechanism 19 can generate airflow in the air duct 18 and allow the airflow to flow out from the lower end of the air outlet section. Specifically, an air inlet 33 is provided at one end of the air inlet section away from the air outlet section. An air outlet 31 is provided at one end of the air outlet section away from the air inlet section. More specifically, the air inlet section is formed with an air inlet 33 on the upper end. An air outlet 31 is formed on the lower end of the air outlet section. The air outlet 31 is used for the air flow in the air pipe 18 to pass through, so that the air flow can flow out of the air outlet section through the air outlet 31. Further, as shown in FIG. 1, for example, the siphon tube 16 is located at the lower end. The lower end of the siphon tube 16 is provided with an opening. The opening forms an air outlet 31.

Therefore, when the fan 21 rotates, the fan 21 can form a negative pressure in the air duct 18, so that air can flow into the air inlet section from the outside of the housing 11, and then generate air flow in the air inlet section and make the air flow from the air outlet. The lower end of the section flows out to form a blower.

In this embodiment, the holding mechanism 26 is provided on the housing 11. Specifically, the holding mechanism 26 may be arranged on the outer wall of the air duct 18. Of course, the holding mechanism 26 is not limited to being provided on the outer wall of the air duct 18. The holding mechanism 26 may also be arranged on the inner wall of the air duct 18, which is not specified in this application. Furthermore, the holding mechanism 26 is fixedly connected to the housing 11. Therefore, the housing 11 can be held by the holding and holding mechanism 26. The fixed connection may be screw connection, bolt connection, welding, integral molding, etc., which is not specified in this application.

In this embodiment, the gripping mechanism 26 includes a gripping portion housing 28 and a support tube 29. One end of the support pipe 29 is connected to the housing 11, and the other end of the support pipe 29 opposite to the housing 11 is connected to the grip housing 28. Specifically, as shown in FIG. 1, the lower end of the support pipe 29 is fixedly inserted into the air pipe 18. The upper end of the support tube 29 is connected to the grip housing 28. The connection method can be screw connection, bolt connection, welding, integral molding, and the like. Therefore, the holding portion housing 28 and the housing 11 can be fixedly connected by the support tube 29. As shown in FIG. More specifically, for example, as shown in FIG. 1, the support tube 29 is fixedly inserted into the upper end of the air inlet section. Further, the support tube 29 is fixedly penetrated in the casing 13. The fixing method can be interference fit, screw connection, welding, etc.

In this embodiment, the grip housing 28 is provided with a grip for the user to hold. Therefore, on the one hand, the hand can be held on the holding part to increase the friction between the palm and the holding mechanism 26; on the other hand, the holding part can be far away from the housing 11, so that the airflow in the air duct 18 can be compared with the operator. The distance is far, and thus avoid the air current to cause harm to the operator. Since the safety regulations of the garden blowing device require that the distance between the grip portion held by the user and the air outlet 31 is greater than 700 mm. However, if the length of the air duct 18 is too long, the air outlet efficiency will be reduced. Therefore, when the length of the air duct 18 is optimal, the holding part housing 28 is placed behind, and the supporting tube 29 is used to support and extend the design requirement of 700 mm.

In this embodiment, the grip housing 28, the support tube 29, the air inlet section and the air outlet section are arranged in sequence in the longitudinally extending direction. That is, the holding portion housing 28 is located at the end of the supporting pipe 29 away from the air pipe 18. The air inlet section is located between the support pipe 29 and the air outlet section. For example, as shown in FIG. 1, the grip housing 28 is located at the upper end of the support tube 29. Specifically, the end of the holding portion housing 28 facing the support tube 29 is sleeved outside the support tube 29. For example, as shown in FIG. 1, the lower end of the holding portion housing 28 is sleeved outside the upper end of the support tube 29.

In this embodiment, the extension direction of the grip portion coincides with the longitudinal extension direction. In this way, the extension direction of the grip portion is consistent with the extension direction of the air outlet section. For example, as shown in Fig. 1, the grip portion and the air outlet section both extend in the up and down direction. In this way, the volume of the garden blowing device in the radial direction can be effectively reduced, so that the volume occupied in the radial direction is the smallest. Thereby reducing the occupied space and improving the flexibility and convenience of operation.

In one embodiment, the grip housing 28, the support tube 29, the air inlet section, and the air outlet section are arranged in a line in the direction of the rotation axis. That is, the holding portion housing 28, the supporting pipe 29, the air inlet section and the air outlet section are arranged in a line. For example, as shown in FIG. 1, the grip housing 28 is located above the support tube 29. The support pipe 29 is located above the air inlet section. The air inlet section is located above the air outlet section. Since the safety regulations of the garden blowing device require that the distance between the grip portion held by the user and the air outlet 31 is greater than 700 mm. However, if the length of the air duct 18 is too long, the air outlet efficiency will be reduced. Therefore, the holding portion housing 28, the supporting pipe 29, the air inlet section and the air outlet section are arranged in a line, and the extension direction of the holding portion is consistent with the longitudinal extension direction, so that the length of the air pipe 18 is equal to The efficiency can be optimized. Specifically, the length of the air pipe 18 can be made smaller to reduce the air loss. The air inlet 33 and the air outlet 31 are in a straight line, the air flow direction is basically unchanged, and the air loss is small.

In one embodiment, the central axes of the grip housing 28, the support tube 29, the air inlet section, and the air outlet section substantially coincide. Thereby, the volume of the garden blowing device in the radial direction is further reduced, thereby further reducing the occupied space of the garden blowing device.

Further, the center of the air outlet 31 is located on the central axis of the holding mechanism 26. Rotating the holding mechanism 26 in this way can accurately control the position of the air outlet 31 of the air duct 18. Furthermore, the operation is more flexible, the rotation is more convenient, and the work directivity is better.

Specifically, the center of the air outlet 31 is located on the central axis of the air duct 18. More specifically, as shown in FIG. 1, the central axis of the casing 13, the central axis of the blow pipe 15 and the central axis of the siphon 16 are all on the same straight line. The air outlet 31 is provided on the lower side of the siphon tube 16.

In one embodiment, the center of the air inlet 33 is located on the central axis of the air duct 18. In this way, the air inlet 33 and the air outlet 31 are in a straight line, the airflow direction is basically unchanged, and the airflow loss is small. Specifically, as shown in FIG. 1, the central axis of the casing 13, the central axis of the blow pipe 15 and the central axis of the siphon 16 are all on the same straight line. The air inlet 33 is provided on the upper side of the casing 13. Therefore, when the fan 21 forms a negative pressure in the air duct 18, the air outside the casing 11 can flow into the air inlet section through the air inlet 33, and flow along the extension direction of the air outlet section until it flows out from the air outlet 31.

Further, the rotation axis of the fan 21 and the central axis of the air duct 18 are located on the same straight line. Specifically, as shown in FIG. 1, the fan 21 is located in the center of the casing 13. In addition, the fan 21 can rotate around the central axis of the casing 13. The central axis of the casing 13 and the central axis of the blow pipe 15 and the central axis of the siphon 16 are all located on the same straight line.

Preferably, a first shock-absorbing member 39 is provided between the support pipe 29 and the air pipe 18. Specifically, the first shock absorber 39 is enclosed between the support tube 29 and the air duct 18. Therefore, when the housing 11 is moved by the holding mechanism 26, impact between the support tube 29 and the inner wall of the air duct 18 can be avoided, thereby reducing the abrasion of the housing 11. The first shock-absorbing member 39 may be sponge, rubber, foam, or the like, for example.

Preferably, a second shock-absorbing member 38 is provided between the support tube 29 and the grip housing 28. Specifically, the second shock absorber 38 is enclosed between the support tube 29 and the grip housing 28. Therefore, when the housing 11 is moved by the holding mechanism 26, impact between the support tube 29 and the inner wall of the holding portion housing 28 can be avoided, thereby reducing the wear of the holding mechanism 26. The second shock-absorbing member 38 may be sponge, rubber, foam, or the like, for example.

Preferably, the support tube 29 is made of a metal material. Therefore, the strength of the support tube 29 can be sufficiently large. The metal material may be iron, copper, aluminum, or the like, for example. Preferably, the support tube 29 is made of aluminum.

In one embodiment, the air inlet 33 and the air outlet 31 are relatively open. That is, the opening direction of the air inlet 33 and the opening direction of the air outlet 31 are opposite to each other in the longitudinally extending direction. For example, as shown in FIG. 1, the air inlet 33 is provided on the upper side of the casing 13. The air outlet 31 is provided on the lower side of the siphon tube 16. The air inlet 33 opens toward the upper side. The air outlet 31 opens toward the lower side. The support tube 29 penetrates through the air inlet 33. In this way, the holding portion housing 28 can be separated from the air inlet 33.

In one embodiment, as shown in FIG. 1, the central axis of the holding mechanism 26 and the central axis of the air duct 18 are located on the same straight line. Specifically, the central axis of the support tube 29, the central axis of the holding portion housing 28, and the central axis of the air duct 18 are on the same straight line. Rotating the holding mechanism 26 in this way can accurately control the position of the air outlet 31 of the air duct 18. Furthermore, the operation is more flexible, the rotation is more convenient, and the work directivity is better.

In another embodiment, the air inlet 33 opens downward when the garden blowing device is in working condition. For example, as shown in Fig. 2, the air inlet 33 opens downward. Therefore, it is possible to prevent the air inlet 33 from facing the operator, thus reducing the injury of the airflow to the operator.

Specifically, the housing 11 includes a first part 35 close to the holding mechanism 26 and a second part 37 located on the side of the first part 35 away from the holding mechanism 26. For example, as shown in FIG. 2, the first part 35 is located on the upper side of the housing 11. The second part 37 is located on the lower side of the housing 11. The first part 35 extends in the longitudinally extending direction. The second portion 37 extends in the longitudinally extending direction. And the first part 35 is located above the second part 37. The first part 35 and the second part 37 are fixedly connected. The fixed connection may be screw connection, bolt connection, welding, integral molding, and the like.

Furthermore, the air duct 18 is arranged in the second part 37. The support tube 29 penetrates through the first part 35. In this way, the housing 11 can be connected to the holding mechanism 26 through the first part 35. Through the second part 37, an air flow can be generated in the housing 11. Specifically, the airflow generating mechanism 19 is provided in the second part 37. For example, as shown in FIG. 2, the air flow generating mechanism 19 is arranged on the side of the second part 37 close to the first part 35. That is, the air flow generating mechanism 19 is provided on the upper side of the second part 37.

Further, the central axis of the first part 35 and the central axis of the second part 37 do not coincide. That is, the central axis of the first part 35 and the central axis of the second part 37 are staggered in the direction perpendicular to the longitudinal extension.

Further, an end of the first part 35 away from the second part 37 is provided with an opening 32 that is opened away from the second part 37 in a longitudinally extending direction. The support tube 29 passes through the opening 32. The air outlet 31 is disposed at an end of the second part 37 away from the first part 35. In addition, the air outlet 31 is opened away from the first part 35 in the longitudinally extending direction. That is, the opening 32 and the air outlet 31 are relatively open in the longitudinally extending direction. However, there is a height difference between the center of the opening 32 and the center of the air outlet 31. The air inlet 33 is disposed at an end of the second part 37 facing the first part 35. For example, as shown in FIG. 2, the air inlet 33 is provided at the upper end of the second part 37. In addition, the air inlet 33 is opened deviating from the longitudinally extending direction. In this way, when the hand is held on the holding portion housing 28, the air inlet 33 is not directly opposite to the hand, so as to prevent the airflow from causing harm to the user.

Further, the end of the second portion 37 facing the first portion 35 deviates from the longitudinal extension direction and extends to form a bent portion. The air inlet 33 is arranged on the bent portion. For example, as shown in FIG. 2, the upper end of the second portion 37 forms a bent portion extending downward.

In one embodiment, the holding part is located below the central axis of the airflow generating mechanism 19 when the garden blowing device is in the working state. This is because when the airflow generating mechanism 19 generates airflow, the airflow flows out through the air outlet and produces a reaction force on the air duct 18. Since the holding part is located below the central axis of the airflow generating mechanism 19 when the garden blowing device is in working condition, when the garden blowing device is in working condition, the force of the airflow on the air duct 18 can generate relative to the holding Torque for turning the upper part upwards. In this way, the air duct 18 can be lifted up by the reaction force of the air flow, thereby saving manpower.

In one embodiment, the garden hair dryer provided by the embodiment of the present application further includes: a battery pack connection interface 41 for connecting a battery pack; or a power plug interface for plugging in an external power source; a battery pack connection interface 41 or a power source The plug-in ports are all arranged at one end of the holding mechanism 26 away from the air duct 18. That is, the battery pack connection interface 41 or the power plug interface and the housing 11 are respectively located on opposite sides of the holding mechanism 26. For example, as shown in FIG. 1, the battery pack connection interface 41 or the power plug interface is located at the upper end of the holding mechanism 26. The housing 11 is located at the lower end of the holding mechanism 26. Therefore, the hand can be held between the battery pack connection port 41 or the power plug port and the housing 11. Further, since the important weight components are the motor and the fan, and both the motor and the fan are arranged at the front end of the holding mechanism 26; and the torque applied to the holding mechanism 26 by the battery pack or external power source and the airflow generating mechanism 19 is opposite, the operation is more Lightweight and flexible.

In one embodiment, the garden blowing device provided by the embodiment of the present application further includes: a battery pack for connecting to the battery pack connection interface 41; or an external power source for connecting to the power plug interface; the battery pack and external The power source is used to provide power to the air flow generating mechanism 19. This ensures that the fan 21 in the air flow generating mechanism 19 can rotate.

Further, the battery pack connection interface 41 or the power plug interface includes a housing. For example, as shown in Fig. 1, the housing is rectangular as a whole. Of course, the housing is not limited to a rectangular shape, and may also have other shapes, such as a hexagonal shape. The shell is used to put a battery pack or an external power source. Specifically, a cavity is provided in the housing. The battery pack or external power source can be installed in the cavity.

Further, a through channel 44 is provided in the holding mechanism 26. Specifically, the through channel 44 includes a first through channel provided in the holding portion housing 28 and a second through channel provided in the support tube 29. For example, as shown in Fig. 1, the first through passage is located on the upper side. The second through passage is located on the lower side. The first through channel is connected to the second through channel. And one end of the first through channel away from the second through channel is communicated with the cavity. For example, as shown in FIG. 1, the upper end of the first through channel is communicated with the cavity. An end of the second through-passage away from the first through-passage communicates with the air duct 18. For example, as shown in FIG. 1, the lower end of the second through passage is communicated with the air duct 18. The through channel 44 is used for a conductor to pass through, and the conductor is used to connect a battery pack or an external power source to the airflow generating mechanism 19. The material of the conductor may be metal, for example. Of course, the conductor is not limited to metal, and can also be other materials, such as graphite, which is not specified in this application. This conductor is used to connect the power supply and the fan 21 and the motor 23. Therefore, through the wire, the power supply can be electrically connected to the fan 21 and the motor 23 to provide power for the fan 21 and the motor 23. By threading the wires in the first through channel and the second through channel, the wires can be extended into the air duct 18 and then connected to the fan 21 and the motor 23 in the air duct 18.

In one embodiment, a control switch 46 is provided on the side of the holding mechanism 26 close to the housing 11. Therefore, when the hand is held on the holding mechanism 26, the finger can easily touch the control switch 46, which can facilitate the operation of the control switch 46 by the finger. The control switch 46 is connected to the air flow generating mechanism 19. Specifically, the control switch 46 is connected to both the motor 23 and the fan 21. The control switch 46 can trigger the operation of the air flow generating mechanism 19 with a finger when the user holds it with one hand. Specifically, the control switch 46 can be used to turn the fan 21 on and off. The control switch 46 can also be used to adjust the rotation speed of the fan 21 and adjust the rotation direction of the fan 21. Further, when the garden blowing device is in the working state, the included angle between the central axis of the air duct 18 and the horizontal plane is an acute angle; and the hand is held on the holding mechanism 26 and the finger can touch the control switch 46.

Specifically, the control switch 46 may be a membrane switch or an optical switch.

In one embodiment, the garden hair dryer provided by the embodiment of the present application further includes a supporting mechanism arranged at an end of the holding portion housing 28 away from the supporting tube 29. For example, the supporting mechanism is provided at the upper end of the holding mechanism 26. The support mechanism is used to support the opponent. Therefore, when the hand is held on the holding mechanism 26, it can be supported by the supporting mechanism to reduce the difficulty of operation.

Please refer to Figure 3 and Figure 4. The garden blowing device provided by an embodiment of the present application includes: a housing 11; it includes an air duct 18; an airflow generating mechanism 19 arranged in the air duct 18; and the airflow generating mechanism 19 is used to generate airflow The battery pack connection interface 41 is used to connect the battery pack; the battery pack provides power for the airflow generating mechanism 19; the holding mechanism 26 is arranged between the battery pack connection interface 41 and the housing 11 , So that the battery pack connection interface 41, the holding mechanism 26 and the housing 11 are arranged in sequence.

It can be seen from the above technical solutions that the garden blowing device described in the embodiment of this application is provided with a housing 11, an air flow generating mechanism 19, a battery pack connection interface 41, and a holding mechanism 26, wherein the holding mechanism 26 is arranged on the battery pack. The connection interface 41 and the housing 11 are connected so that the battery pack connection interface 41, the holding mechanism 26 and the housing 11 are arranged in sequence. Since the important weight components are the motor, fan, and battery pack, and the motor and fan are all set at one end of the holding mechanism 26; the battery pack is set at the other end of the holding mechanism 26, so the battery pack and the airflow generating mechanism 19 are opposed to the holding mechanism 26. The applied torque is opposite, so the operation is lighter and more flexible.

In this embodiment, as shown in FIGS. 3 and 4, the housing 11 has a hollow rod shape as a whole. The hollow part forms a through channel 44. Of course, the housing 11 is not limited to a rod shape, but may also have other shapes; for example, a cube shape, which is not specified in this application. The housing 11 includes an air duct 18. The air duct 18 forms a through channel 44. Specifically, the air duct 18 includes an air inlet section and an air outlet section. The air outlet section extends longitudinally. As shown in FIG. 3, the air duct 18 extends in the left-right direction. The air pipe 18 is used for passing airflow, so that the air pipe 18 can blow outward.

In this embodiment, the airflow generating mechanism 19 is used to generate airflow. Specifically, the air flow generating mechanism 19 includes a fan 21 and a motor 23 for driving the fan 21 to rotate. Therefore, when the fan 21 rotates, the fan 21 can form a negative pressure in the air duct 18, so that air can flow into the air inlet section from the outside of the housing 11, and then generate air flow in the air inlet section, and make the air flow from the air outlet. The right end of the segment flows out to form a blower.

In this embodiment, the battery pack connection interface 41 is used to connect the battery pack. The battery pack provides power to the air flow generating mechanism 19. Therefore, when the battery pack is installed on the installation interface, the torque applied by the battery pack and the airflow generating mechanism 19 to the holding mechanism 26 is opposite, so the operation is lighter and more flexible.

Further, the holding mechanism 26 includes a holding portion housing 28 and a support tube 29. One end of the support pipe 29 is connected to the housing 11, and the other end of the support pipe 29 opposite to the housing 11 is connected to the grip housing 28. Specifically, for example, as shown in FIG. 3, the right end of the support tube 29 is fixedly inserted into the air tube 18. The left end of the support tube 29 is connected to the grip housing 28. The connection method can be screw connection, bolt connection, welding, integral molding, and the like. Therefore, the holding portion housing 28 and the housing 11 can be fixedly connected by the support tube 29.

In this embodiment, the grip housing 28, the support tube 29, the air inlet section and the air outlet section are arranged in sequence in the longitudinally extending direction. That is, the holding portion housing 28 is located at the end of the supporting pipe 29 away from the air pipe 18. The air inlet section is located between the support pipe 29 and the air outlet section. For example, as shown in FIG. 3, the grip housing 28 is located at the left end of the support tube 29. Specifically, the end of the holding portion housing 28 facing the support tube 29 is sleeved outside the support tube 29. For example, as shown in FIG. 1, the lower end of the holding portion housing 28 is sleeved outside the upper end of the support tube 29.

In this embodiment, the extension direction of the grip portion coincides with the longitudinal extension direction. In this way, the extension direction of the grip portion is consistent with the extension direction of the air outlet section. For example, as shown in Fig. 3, both the holding portion and the air outlet section extend in the left-right direction. In this way, the volume of the garden blowing device in the radial direction can be effectively reduced, so that the volume occupied in the radial direction is the smallest. Thereby reducing the occupied space and improving the flexibility and convenience of operation.

In one embodiment, the holding portion housing 28, the support tube 29, the air inlet section and the air outlet section are arranged in a line in the longitudinal direction. That is, the holding portion housing 28, the supporting pipe 29, the air inlet section and the air outlet section are arranged in a line. For example, as shown in FIG. 3, the grip housing 28 is located at the left end of the support tube 29. The support pipe 29 is located at the left end of the air inlet section. The inlet section is located at the left end of the outlet section. Since the safety regulations of the garden blowing device require that the distance between the grip portion held by the user and the air outlet 31 is greater than 700 mm. However, if the length of the air duct 18 is too long, the air outlet efficiency will be reduced. Therefore, the holding portion housing 28, the supporting pipe 29, the air inlet section and the air outlet section are arranged in a line, and the extension direction of the holding portion is consistent with the longitudinal extension direction, so that the length of the air pipe 18 is equal to The efficiency can be optimized. Specifically, the length of the air pipe 18 can be made smaller to reduce the air loss. The air inlet 33 and the air outlet 31 are in a straight line, the air flow direction is basically unchanged, and the air loss is small.

In one embodiment, the holding part is located below the central axis of the airflow generating mechanism 19 when the garden blowing device is in the working state. This is because when the airflow generating mechanism 19 generates airflow, the airflow flows out through the air outlet and produces a reaction force on the air duct 18. Since the holding part is located below the central axis of the airflow generating mechanism 19 when the garden blowing device is in working condition, when the garden blowing device is in working condition, the force of the airflow on the air duct 18 can generate relative to the holding Torque for turning the upper part upwards. In this way, the air duct 18 can be lifted up by the reaction force of the air flow, thereby saving manpower. When the garden blowing device is in working condition, the included angle between the central axis of the air duct 18 and the horizontal plane is an acute angle.

In one embodiment, the support tube 29 is in a bent shape. When the garden blowing device is placed horizontally, one end of the support tube 29 connected to the housing 11 and the other end of the support tube 29 connected to the holding portion housing 28 are not at the same height. For example, as shown in Figure 3, the garden blowing device is placed horizontally. The grip housing 28 extends in the left-right direction. The support tube 29 extends upwards obliquely, so as to connect the holding portion housing 28 with the air duct 18. The right end of the support tube 29 is connected to the housing. The left end of the support tube 29 is connected to the grip housing 28. The right end of the support tube 29 is higher than the left end of the support tube 29. As shown in Figure 4, the garden blowing device is placed horizontally. The grip housing 28 extends obliquely upward. The support tube 29 extends upwards obliquely, so as to connect the holding portion housing 28 with the air duct 18. The right end of the support tube 29 is connected to the housing. The left end of the support tube 29 is connected to the grip housing 28. The right end of the support tube 29 is higher than the left end of the support tube 29.

Further, the central axis of the grip portion is substantially parallel to the central axis of the air flow generating mechanism 19. For example, as shown in FIG. 3, the central axis of the grip portion extends in the left-right direction. The central axis of the airflow generating mechanism 19 extends in the left-right direction.

In another embodiment, the gripping portion is arranged at an angle to the central axis of the airflow generating mechanism 19. Specifically, for example, as shown in FIG. 4, the grip portion extends obliquely upward. In addition, the central axis of the support tube 29 roughly coincides with the central axis of the grip housing 28. The central axis of the airflow generating mechanism 19 extends in the left-right direction. This is because when the airflow generating mechanism 19 generates airflow, the airflow flows out through the air outlet and produces a reaction force on the air duct 18. And because the holding part is located below the air flow generating mechanism 19 when the garden blowing device is in working state, when the garden blowing device is in working state, the force of the air flow on the air duct 18 can generate upward force on the air duct 18 relative to the holding part. Torque of rotation. In this way, the air duct 18 can be lifted up by the reaction force of the air flow, thereby saving manpower.

Furthermore, a control switch 46 is provided on the side of the holding mechanism 26 close to the housing 11. Therefore, when the hand is held on the holding mechanism 26, the finger can easily touch the control switch 46, which can facilitate the operation of the control switch 46 by the finger. The control switch 46 is connected to the air flow generating mechanism 19. Specifically, the control switch 46 is connected to both the motor 23 and the fan 21. The control switch 46 can trigger the operation of the air flow generating mechanism 19 with a finger when the user holds it with one hand. Specifically, the control switch 46 can be used to turn the fan 21 on and off. The control switch 46 can also be used to adjust the rotation speed of the fan 21 and adjust the rotation direction of the fan 21. Further, when the garden blowing device is in the working state, the included angle between the central axis of the air duct 18 and the horizontal plane is an acute angle; and the hand is held on the holding mechanism 26 and the finger can touch the control switch 46.

Further, the garden hair dryer of the embodiment of the present application further includes: a supporting mechanism arranged at an end of the holding portion housing 28 away from the supporting tube 29.
