Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1 and fig. 2. An embodiment of the present application provides a garden blower, comprising: a housing 11; the air-conditioning system comprises an air pipe 18, wherein the air pipe 18 comprises an air inlet section and an air outlet section, and the air outlet section lengthily extends; an airflow generating mechanism 19 provided in the air duct 18; the air flow generating mechanism 19 is used for generating air flow and comprises a fan 21 and a motor 23 for driving the fan 21 to rotate around a rotation axis; the air inlet section and the air outlet section are respectively positioned at the upstream and the downstream of the airflow generating mechanism 19 in the flowing direction of the airflow; a grip mechanism 26 including a grip housing 28 and a support tube 29; one end of the support tube 29 is connected to the housing 11, the other end of the support tube 29 opposite to the housing 11 is connected to the holding part housing 28, and the holding part housing 28 is provided with a holding part for a user to hold; the holding part shell 28, the supporting tube 29, the air inlet section and the air outlet section are sequentially arranged in the direction of the rotation axis; the extending direction of the holding part is consistent with the rotating axis direction. The projection of the grip portion onto the plane of rotation of the fan falls within the range of the projection of the air duct onto this plane of rotation. In this embodiment, the rotation axis direction of the fan is consistent with the longitudinal extension direction of the air outlet section.

When the air-flow-generating device is used, a user holds the holding part by hand and generates air flow through 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. Thus forming a blow.

The technical scheme shows that: the garden blowing device according to the embodiment of the present application is provided with a housing 11, an airflow generating mechanism 19 and a holding mechanism 26, wherein a holding portion housing 28, a support tube 29, an air inlet section and an air outlet section are sequentially arranged in a lengthwise extending direction; the extending direction of the holding part is consistent with the lengthwise extending direction; thereby effectively reducing the volume of the garden blowing device in the radial direction and ensuring that the volume occupied by the garden blowing device in the radial direction is minimum. Thereby reducing the occupied space and improving the flexibility and the convenience of operation. Further, the safety regulations of garden blowing devices require that the distance between the holding part held by the user and the air outlet 31 is more than 700 mm. However, if the length of the duct 18 is too long, the air outlet efficiency is reduced. Therefore, under the condition that the length of the air duct 18 is optimal, the holding part shell 28 is arranged at the rear, and the supporting pipe 29 is adopted to support and prolong the design requirement of ensuring 700 mm.

In the present embodiment, as shown in fig. 1, the housing 11 is a hollow rod as a whole. The hollow portion forms a through passage 44. Of course, the housing 11 is not limited to a rod shape, and may have other shapes; for example, a square shape, and this application does not intend to limit the present invention. The housing 11 includes an air duct 18. The duct 18 forms a through passage 44. Specifically, the air duct 18 includes an air inlet section and an air outlet section. The air outlet section extends lengthwise. As shown in fig. 1, the duct 18 extends in the up-down direction. The air duct 18 is used for passing air flow so that the air duct 18 can blow air outwards.

Further, the housing 11 may include a casing 13, a blow pipe 15, and a siphon pipe 16 arranged in a direction extending lengthwise. The casing 13, the blow pipe 15, and the siphon pipe 16 are all hollow structures. And the cabinet 13, the blow pipe 15, and the siphon pipe 16 are communicated with each other to form an air duct 18. The inner diameter of the housing 13 is larger than the inner diameter of the blow pipe 15. So that the housing 13 can house the airflow generating mechanism 19 therein. The siphon tube 16 has an inner diameter larger than that of the blow pipe 15. Thereby increasing the velocity of the air flow as it flows from the lance tube 15 to the siphon tube 16 within the ductwork 18, thus facilitating the flow of air out of the siphon tube 16.

In the present embodiment, the duct 18 has opposite ends in the direction in which the duct extends lengthwise. Such as shown in fig. 1, which are the upper and lower ends of the air duct 18, respectively.

In the present embodiment, the airflow generation mechanism 19 is provided in the duct 18. Specifically, the airflow generating mechanism 19 may be fixedly disposed in the air duct 18. The fixing method may be screw fixing, bolt fixing, or the like, and this application does not specify this.

Further, the airflow generating mechanism 19 may be provided to any portion of the duct 18. For example, the air flow generating mechanism 19 may be disposed between the ends of the air duct 18. The airflow generating mechanism 19 may also be provided in either of the two ends of the air duct 18. I.e. the air flow generating means 19 is arranged in the upper end of the air duct 18. Or the air flow generating means 19 is provided in the lower end of the air duct 18.

Preferably, in order to enable the air flow generating means 19 to create a steady air flow within the air duct 18, the air flow generating means 19 is provided in either end of the air duct 18. The airflow generating mechanism 19 is provided at the upper end of the air duct 18, as shown in fig. 1, for example. Specifically, the housing 13 is located at the upper end. The airflow generating mechanism 19 is disposed in the housing 13.

In the present embodiment, the airflow generation mechanism 19 is used to generate an airflow. The air inlet section and the air outlet section are respectively positioned at the upstream and the downstream of the airflow generating mechanism 19 in the flowing direction of the airflow. That is, the airflow generating mechanism 19 divides the air duct 18 into an air inlet section and an air outlet section. For example, as shown in fig. 1, the air inlet section is located above the air outlet section. Thereby enabling the air current to flow to the air outlet section from the air inlet section and flow 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 make the airflow flow out from the lower end of the air outlet section. Specifically, one end of the air inlet section, which is far away from the air outlet section, is provided with an air inlet 33. The air outlet 31 is arranged at one end of the air outlet section far away from the air inlet section. More specifically, the air intake section is formed with an air intake opening 33 on an upper end. The air outlet section is formed with an air outlet 31 on the lower end. The air outlet 31 is used for the air flow in the air supply pipe 18 to pass through, so that the air flow can flow out of the air outlet section through the air outlet 31. Further, a siphon 16 is located at the lower end, as shown in fig. 1, for example. The siphon tube 16 is provided with an opening at its lower end. The opening forms an outlet opening 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 airflow is generated in the air inlet section, and the airflow flows out from the lower end of the air outlet section, so as to form a blowing air.

In the present embodiment, the gripping mechanism 26 is provided on the housing 11. Specifically, the gripping mechanism 26 may be disposed on an outer wall of the air duct 18. Of course, the gripping mechanism 26 is not limited to being disposed on the outer wall of the air duct 18. The holding mechanism 26 may also be disposed on the inner wall of the air duct 18, which is not specified in this application. Further, the holding mechanism 26 is fixedly connected to the housing 11. So that the housing 11 can be gripped by gripping the gripping mechanism 26. The fixed connection may be a screw connection, a bolt connection, a welding, an integral molding, etc., and is not specified in this application.

In the present embodiment, the grip mechanism 26 includes a grip housing 28 and a support pipe 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 section housing 28. Specifically, as shown in fig. 1, the lower end of the support tube 29 is fixedly inserted into the air duct 18. The upper end of the support tube 29 is connected to the grip housing 28. The connection mode can be screw connection, bolt connection, welding, integral forming and the like. So that the grip housing 28 can be fixedly connected to the housing 11 via the support tube 29. More specifically, as shown in fig. 1, for example, a support pipe 29 is fixedly disposed through the upper end of the air intake section. Further, the support tube 29 is fixedly inserted into the housing 13. The fixing means may be interference fit, screw connection, welding, etc.

In the present embodiment, the grip housing 28 is provided with a grip portion to be gripped by a user. So that on the one hand the hand can be held on the grip portion to increase the friction between the palm and the gripping means 26; on the other hand, the grip portion can be far away from the housing 11, so that the airflow in the air duct 18 is far away from the operator, thereby avoiding the airflow from causing injury to the operator. The safety specification of the garden blowing device requires that the distance between the holding part held by the user and the air outlet 31 is more than 700 mm. However, if the length of the duct 18 is too long, the air outlet efficiency is reduced. Therefore, under the condition that the length of the air duct 18 is optimal, the holding part shell 28 is arranged at the rear, and the supporting pipe 29 is adopted to support and prolong the design requirement of ensuring 700 mm.

In the present embodiment, the grip housing 28, the support tube 29, the air inlet section, and the air outlet section are arranged in this order in the direction in which the longitudinal direction extends. I.e. the grip housing 28, is located at the end of the support tube 29 remote from the air duct 18. The air inlet section is positioned 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 grip housing 28 facing the support tube 29 is fitted over the support tube 29. For example, as shown in fig. 1, the lower end of the grip housing 28 is fitted over the upper end of the support tube 29.

In the present embodiment, the extending direction of the grip portion coincides with the longitudinal extending direction. The extending direction of the holding part is consistent with the extending direction of the air outlet section. For example, as shown in fig. 1, the holding portion and the air outlet section both extend in the vertical direction. Therefore, the volume of the garden blowing device in the radial direction can be effectively reduced, and the volume occupied by the garden blowing device in the radial direction is the minimum. 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 straight line in the direction of the rotation axis. That is, the grip housing 28, the support tube 29, the air inlet section, and the air outlet section are arranged in a straight line. For example, as shown in fig. 1, the grip housing 28 is located above the support tube 29. The support tube 29 is located above the air intake section. The air inlet section is positioned above the air outlet section. The safety specification of the garden blowing device requires that the distance between the holding part held by the user and the air outlet 31 is more than 700 mm. However, if the length of the duct 18 is too long, the air outlet efficiency is reduced. Therefore, the holding portion shell 28, the support tube 29, the air inlet section and the air outlet section are arranged in a straight line, and the extending direction of the holding portion is consistent with the lengthwise extending direction, so that the length and the efficiency of the air pipe 18 can be optimized, specifically, the length of the air pipe 18 can be reduced, the air outlet loss is reduced, the air inlet 33 and the air outlet 31 are on the same straight line, the air flow direction is basically unchanged, and the air flow 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 further reducing the volume of the garden blower in the radial direction and thus further reducing the space taken up by the garden blower.

Further, the air outlet 31 is centered on the central axis of the holding mechanism 26. Rotating the gripping mechanism 26 in this manner accurately controls the position of the outlet opening 31 of the air hose 18. And further 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 center axis of the casing 13, the center axis of the blow pipe 15, and the center axis of the siphon pipe 16 are all aligned. The outlet 31 is provided below the siphon tube 16.

In one embodiment, the air inlet 33 is centered on the central axis of the air duct 18. Therefore, the air inlet 33 and the air outlet 31 are in the same 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 pipe 16 are all aligned. The intake vent 33 is provided at an upper side of the cabinet 13. Therefore, when the fan 21 forms negative pressure in the air duct 18, air outside the housing 11 can flow into the air inlet section through the air inlet 33 and flow along the extending direction of the air outlet section until flowing out of the air outlet 31.

Further, the rotation axis of the fan 21 is aligned with the central axis of the air duct 18. Specifically, as shown in fig. 1, the fan 21 is located at the center of the cabinet 13. And the fan 21 can rotate around the central axis of the housing 13. The central axis of the housing 13 is aligned with the central axis of the blow pipe 15 and the central axis of the siphon pipe 16.

Preferably, a first damper 39 is provided between the support pipe 29 and the air duct 18. In particular, the first damper 39 is enclosed between the support tube 29 and the air duct 18. Thus, when the housing 11 is moved by the holding mechanism 26, the impact between the support tube 29 and the inner wall of the air duct 18 can be avoided, and the wear of the housing 11 can be reduced. The first shock absorbing member 39 may be, for example, a sponge, rubber, foam, or the like.

Preferably, a second damper 38 is provided between the support tube 29 and the grip housing 28. Specifically, the second damper 38 is enclosed between the support tube 29 and the grip housing 28. Thus, when the housing 11 is moved by the gripping mechanism 26, the impact between the support pipe 29 and the inner wall of the grip housing 28 can be avoided, and the abrasion of the gripping mechanism 26 can be reduced. The second shock absorbing member 38 may be, for example, a sponge, rubber, foam, or the like.

Preferably, the support tube 29 is made of a metallic material. So that the support tube 29 can be sufficiently strong. The metal material may be, for example, iron, copper, aluminum, or the like. Preferably, the support tube 29 is made of aluminum.

In one embodiment, the intake vent 33 and the exhaust vent 31 are relatively open. That is, the opening direction of the inlet vent 33 and the opening direction of the outlet vent 31 are opposite to each other in the direction in which the longitudinal direction extends. For example, as shown in fig. 1, the intake vent 33 is provided at an upper side of the cabinet 13. The outlet 31 is provided below the siphon tube 16. The intake vent 33 is open toward the upper side. The outlet port 31 is open toward the lower side. The support tube 29 is inserted into the air inlet 33. This allows the grip portion housing 28 to be distant from the air inlet 33.

In one embodiment, as shown in FIG. 1, the central axis of the gripping mechanism 26 is aligned with the central axis of the air hose 18. Specifically, the central axis of the support tube 29, the central axis of the grip housing 28, and the central axis of the air duct 18 are on the same straight line. Rotating the gripping mechanism 26 in this manner accurately controls the position of the outlet opening 31 of the air hose 18. And further the operation is more flexible, the rotation is more convenient and the work directivity is better.

In another embodiment, the air inlet opening 33 is open downwards when the garden blower is in operation. For example, as shown in fig. 2, the intake vent 33 is open downward. Thereby preventing the air inlet 33 from facing the operator, and thus reducing the damage of the air flow to the operator.

Specifically, the housing 11 includes a first portion 35 adjacent to the gripping mechanism 26 and a second portion 37 on a side of the first portion 35 remote from the gripping mechanism 26. The first portion 35 is located on the upper side of the housing 11, as shown in fig. 2, for example. The second portion 37 is located on the underside of the housing 11. The first portion 35 extends in a direction of longitudinal extension. The second portion 37 extends in a direction of longitudinal extension. And the first portion 35 is located above the second portion 37. The first part 35 and the second part 37 are fixedly connected. The fixed connection mode can be screw connection, bolt connection, welding, integral forming and the like.

Further, the air duct 18 is disposed within the second portion 37. The support tube 29 is disposed through the first portion 35. This enables the housing 11 to be connected to the holding means 26 via the first part 35. The second part 37 enables an air flow to be generated in the housing 11. Specifically, the airflow generating mechanism 19 is disposed within the second portion 37. For example, as shown in fig. 2, the airflow generating mechanism 19 is disposed on a side of the second portion 37 adjacent to the first portion 35. That is, the airflow generating mechanism 19 is provided on the upper side of the second portion 37.

Further, the central axis of the first portion 35 is not coincident with the central axis of the second portion 37. I.e. the central axis of the first portion 35 is offset from the central axis of the second portion 37 in a direction perpendicular to the longitudinal extension.

Further, an end of the first portion 35 remote from the second portion 37 is provided with an opening 32 which is open in the direction of longitudinal extension away from the second portion 37. A support tube 29 is disposed through the opening 32. The outlet opening 31 is disposed at an end of the second portion 37 remote from the first portion 35. And the outlet opening 31 is open opposite the first portion 35 in the direction of longitudinal extension. I.e. the opening 32 and the outlet mouth 31 are relatively open in the direction of longitudinal extension. But with a height difference between the center of the opening 32 and the center of the outlet opening 31. The air inlet opening 33 is provided at an end of the second portion 37 facing the first portion 35. For example, as shown in fig. 2, the intake vent 33 is provided at an upper end of the second portion 37. And the air inlet opening 33 is opened deviating from the lengthwise extending direction. Thus, when the hand is held on the grip portion housing 28, the air inlet 33 is not opposite to the hand, thereby preventing the air flow from causing damage to the user.

Further, one end of the second portion 37 facing the first portion 35 extends away from the lengthwise extending direction to form a bent portion. The air inlet 33 is disposed on the bending portion. The upper end of the second portion 37 forms a downwardly extending bend, as shown in figure 2 for example.

In one embodiment, the grip is located below the central axis of the air flow generating means 19 when the garden blower is in operation. When the airflow generating mechanism 19 generates airflow, the airflow flows out through the air outlet and generates a reaction force on the air duct 18. Since the grip is located below the central axis of the air flow generating means 19 when the garden blower is in operation, the force of the air flow on the air hose 18 can generate a torque on the air hose 18 that is upwardly directed relative to the grip when the garden blower is in operation. In this way, the air duct 18 can be lifted upwards by the reaction force of the air flow, thereby saving manpower.

In one embodiment, the garden blowing device provided by the embodiment of the present application further includes: a battery pack connection interface 41 for connecting a battery pack; or the power supply interface is used for plugging an external power supply; the battery pack connection port 41 or the power supply plug port is disposed at an end of the holding mechanism 26 remote from the air hose 18. I.e., the battery pack connection port 41 or the power supply jack, and the housing 11 are located on opposite sides of the holding mechanism 26, respectively. For example, as shown in fig. 1, a battery pack connection port 41 or a power supply jack is located at the upper end of the gripping mechanism 26. The housing 11 is located at the lower end of the gripping mechanism 26. So that the hand can be held between the battery pack connection port 41 or the power supply jack and the housing 11. Further, since the important weight components are the motor and the fan, and both the motor and the fan are provided at the front end of the holding mechanism 26; and the torque applied by the battery pack or the external power supply and the airflow generating mechanism 19 to the holding mechanism 26 is opposite, so the operation is lighter and more flexible.

In one embodiment, the garden blowing device provided by the embodiment of the present application further includes: a battery pack for connection to the battery pack connection interface 41; or an external power supply for connecting to the power supply interface; both the battery pack and the external power source are used to power the airflow generating mechanism 19. Thereby ensuring that the fan 21 in the airflow generating mechanism 19 can be rotated.

Further, the battery pack connection interface 41 or the power supply jack includes a housing. For example, as shown in fig. 1, the housing is rectangular in shape as a whole. Of course, the housing is not limited to a rectangular shape, but may have other shapes, such as a hexagonal shape. The shell is used for placing a battery pack or an external power supply. Specifically, a cavity is provided within the housing. The battery pack or an external power source can be mounted within the cavity.

Further, a through passage 44 is provided in the holding mechanism 26. Specifically, the through passage 44 includes a first through passage provided in the grip section housing 28 and a second through passage 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 passage and the second through passage communicate with each other. And one end of the first through channel, which is far 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 passage communicates with the cavity. The end of the second through passage remote from the first through passage communicates with the air duct 18. The lower end of the second through passage communicates with an air duct 18, as shown in fig. 1, for example. The through-passage 44 is used for passing a conductor for connecting the battery pack or an external power source to the airflow generating mechanism 19. The material of the conductor may be, for example, metal. Of course, the conductor is not limited to metal, and may be made of other materials, such as graphite, and the like, and the present application does not limit the conductor. Which conductors are used to connect the power supply to the fan 21 and the motor 23. So that the power source can be electrically connected to the fan 21 and the motor 23 through the wires to supply power to the fan 21 and the motor 23. The wire can be extended into the air duct 18 by penetrating the wire into the first through passage and the second through passage, and then is connected with the fan 21 and the motor 23 in the air duct 18.

In one embodiment, a control switch 46 is provided on a side of the gripping mechanism 26 adjacent the housing 11. So that the control switch 46 can be easily touched by a finger when the hand is held on the holding mechanism 26, thereby facilitating the operation of the control switch 46 by the finger. The control switch 46 is connected to the airflow generating mechanism 19. Specifically, the control switch 46 is connected to both the motor 23 and the fan 21. The control switch 46 is capable of finger-actuated operation of the airflow generating mechanism 19 when held in one hand of a user. In particular, the control switch 46 may be used to turn the fan 21 on and off. The control switch 46 may also be used to adjust the rotational speed of the fan 21 and to adjust the direction of rotation of the fan 21. Further, when the garden blowing device is in a working state, an included angle between the central axis of the air pipe 18 and the horizontal plane is an acute angle; and held by hand on the gripping mechanism 26 and the finger can touch the control switch 46.

Specifically, the control switch 46 may be a membrane switch or a light-sensitive switch.

In one embodiment, the garden blowing device provided by the embodiment of the present application further includes: a support mechanism provided at an end of the grip housing 28 remote from the support tube 29. For example, the support mechanism is provided at the upper end of the holding mechanism 26. The supporting mechanism is used for supporting the hand. Therefore, when the hand is held on the holding mechanism 26, the operation difficulty can be reduced through the support of the supporting mechanism.

Please refer to fig. 3 and 4. An embodiment of the present application provides a garden blower, comprising: a housing 11; it includes an air duct 18; an airflow generating mechanism 19 provided in the air duct 18; the airflow generating mechanism 19 is used for generating airflow; a battery pack connection interface 41 for connecting a battery pack; the battery pack supplies power to the airflow generation mechanism 19; a holding mechanism 26 disposed between the battery pack connection port 41 and the housing 11, such that the battery pack connection port 41, the holding mechanism 26, and the housing 11 are arranged in sequence.

The technical scheme shows that: the garden blower according to the embodiment of the present application is provided with a housing 11, an airflow generating mechanism 19, a battery pack connecting port 41, and a holding mechanism 26, wherein the holding mechanism 26 is disposed between the battery pack connecting port 41 and the housing 11, so that the battery pack connecting port 41, the holding mechanism 26, and the housing 11 are sequentially arranged. Because the important weight parts are the motor, the fan and the battery pack, and the motor and the fan are arranged at one end of the holding mechanism 26; the battery pack is arranged at the other end of the holding mechanism 26, so that the torque applied to the holding mechanism 26 by the battery pack and the airflow generating mechanism 19 is opposite, and the operation is lighter and more flexible.

In the present embodiment, as shown in fig. 3 and 4, the housing 11 is a hollow rod as a whole. The hollow portion forms a through passage 44. Of course, the housing 11 is not limited to a rod shape, and may have other shapes; for example, a square shape, and this application does not intend to limit the present invention. The housing 11 includes an air duct 18. The duct 18 forms a through passage 44. Specifically, the air duct 18 includes an air inlet section and an air outlet section. The air outlet section extends lengthwise. As shown in fig. 3, the duct 18 extends in the left-right direction. The air duct 18 is used for passing air flow so that the air duct 18 can blow air outwards.

In the present embodiment, the airflow generation mechanism 19 is used to generate an airflow. Specifically, the airflow 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 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 airflow is generated in the air inlet section, and the airflow flows out from the right end of the air outlet section, so as to form blowing.

In the present embodiment, the battery pack connection interface 41 is used to connect a battery pack. The battery pack supplies power to the airflow generating mechanism 19. Thus, when the battery pack is mounted on the mounting interface, the torque applied by the battery pack and the airflow generating mechanism 19 to the holding mechanism 26 is opposite, so that the operation is lighter and more flexible.

Further, the grip mechanism 26 includes a grip 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 section housing 28. Specifically, as shown in fig. 3, for example, the right end of the support pipe 29 is fixedly inserted into the air pipe 18. The left end of the support tube 29 is connected to the grip housing 28. The connection mode can be screw connection, bolt connection, welding, integral forming and the like. So that the grip housing 28 can be fixedly connected to the housing 11 via the support tube 29.

In the present embodiment, the grip housing 28, the support tube 29, the air inlet section, and the air outlet section are arranged in this order in the direction in which the longitudinal direction extends. I.e. the grip housing 28, is located at the end of the support tube 29 remote from the air duct 18. The air inlet section is positioned 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 grip housing 28 facing the support tube 29 is fitted over the support tube 29. For example, as shown in fig. 1, the lower end of the grip housing 28 is fitted over the upper end of the support tube 29.

In the present embodiment, the extending direction of the grip portion coincides with the longitudinal extending direction. The extending direction of the holding part is consistent with the extending direction of the air outlet section. For example, as shown in fig. 3, the grip portion and the air outlet section both extend in the left-right direction. Therefore, the volume of the garden blowing device in the radial direction can be effectively reduced, and the volume occupied by the garden blowing device in the radial direction is the minimum. 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 straight line in the longitudinal direction. That is, the grip housing 28, the support tube 29, the air inlet section, and the air outlet section are arranged in a straight 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 tube 29 is located at the left end of the air intake section. The air inlet section is positioned at the left end of the air outlet section. The safety specification of the garden blowing device requires that the distance between the holding part held by the user and the air outlet 31 is more than 700 mm. However, if the length of the duct 18 is too long, the air outlet efficiency is reduced. Therefore, the holding portion shell 28, the support tube 29, the air inlet section and the air outlet section are arranged in a straight line, and the extending direction of the holding portion is consistent with the lengthwise extending direction, so that the length and the efficiency of the air pipe 18 can be optimized, specifically, the length of the air pipe 18 can be reduced, the air outlet loss is reduced, the air inlet 33 and the air outlet 31 are on the same straight line, the air flow direction is basically unchanged, and the air flow loss is small.

In one embodiment, the grip is located below the central axis of the air flow generating means 19 when the garden blower is in operation. When the airflow generating mechanism 19 generates airflow, the airflow flows out through the air outlet and generates a reaction force on the air duct 18. Since the grip is located below the central axis of the air flow generating means 19 when the garden blower is in operation, the force of the air flow on the air hose 18 can generate a torque on the air hose 18 that is upwardly directed relative to the grip when the garden blower is in operation. In this way, the air duct 18 can be lifted upwards by the reaction force of the air flow, thereby saving manpower. When the garden blower is in operation, the included angle between the central axis of the air pipe 18 and the horizontal plane is an acute angle.

In one embodiment, the support tube 29 is bent such that when the garden blower is in a horizontal position, the end of the support tube 29 connected to the housing 11 is not at the same height as the other end of the support tube 29 connected to the grip housing 28. For example, as shown in fig. 3, the garden blowing device is horizontally positioned. The grip housing 28 extends in the left-right direction. The support tube 29 extends obliquely upward and connects the grip housing 28 to the air hose 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 support tube 29 has a right end higher than a left end of the support tube 29. As shown in fig. 4, the garden blowing device is horizontally positioned. The grip housing 28 extends obliquely upward. The support tube 29 extends obliquely upward and connects the grip housing 28 to the air hose 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 support tube 29 has a right end higher than a left end of the support tube 29.

Further, the central axis of the grip portion is substantially parallel to the central axis of the airflow generation 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 generation mechanism 19 extends in the left-right direction.

In another embodiment, the gripping portion is disposed at an angle to the central axis of the airflow generating mechanism 19. Specifically, the grip portion extends obliquely upward as shown in fig. 4, for example. And the central axis of the support tube 29 substantially coincides with the central axis of the grip section housing 28. The central axis of the airflow generation mechanism 19 extends in the left-right direction. When the airflow generating mechanism 19 generates airflow, the airflow flows out through the air outlet and generates a reaction force on the air duct 18. And because the holding part is positioned below the airflow generating mechanism 19 when the garden blower is in the working state, the acting force of the airflow on the air duct 18 can generate torque which rotates upwards relative to the holding part on the air duct 18 when the garden blower is in the working state. In this way, the air duct 18 can be lifted upwards by the reaction force of the air flow, thereby saving manpower.

Further, a control switch 46 is provided on a side of the holding mechanism 26 close to the housing 11. So that the control switch 46 can be easily touched by a finger when the hand is held on the holding mechanism 26, thereby facilitating the operation of the control switch 46 by the finger. The control switch 46 is connected to the airflow generating mechanism 19. Specifically, the control switch 46 is connected to both the motor 23 and the fan 21. The control switch 46 is capable of finger-actuated operation of the airflow generating mechanism 19 when held in one hand of a user. In particular, the control switch 46 may be used to turn the fan 21 on and off. The control switch 46 may also be used to adjust the rotational speed of the fan 21 and to adjust the direction of rotation of the fan 21. Further, when the garden blowing device is in a working state, an included angle between the central axis of the air pipe 18 and the horizontal plane is an acute angle; and held by hand on the gripping mechanism 26 and the finger can touch the control switch 46.

Further, the garden blowing device of the embodiment of the present application further includes: a support mechanism provided at an end of the grip housing 28 remote from the support tube 29. The supporting mechanism is used for supporting the hand. Therefore, when the hand is held on the holding mechanism 26, the operation difficulty can be reduced through the support of the supporting mechanism.
