DETAILED DESCRIPTION
[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0048] See also Figure 1 and Figure 2 . The garden hair dryer provided in one embodiment of the present application includes: a shell 11; an air duct 18, wherein the air duct 18 includes an air inlet section and an air outlet section, wherein the air outlet section extends longitudinally; an air flow generating mechanism 19, which is arranged in the air duct 18; the air flow generating mechanism 19 is used to generate air flow, 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 section are respectively located upstream and downstream of the air flow generating mechanism 19 in the flow direction of the air flow; a gripping mechanism 26, including a gripping portion shell 28 and a support tube 29; one end of the support tube 29 is connected to the shell 11, and the other end of the support tube 29 opposite to the shell 11 is connected to the gripping portion shell 28, and the gripping portion shell 28 is provided with a gripping portion for a user to grip; the gripping portion shell 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 extending direction of the gripping portion is consistent with the direction of the rotation axis. The projection of the grip portion 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.
[0049] When in use, the hand holds the grip portion, and the airflow is generated by the airflow generating mechanism 19, so that the airflow flows from the air inlet section to the air outlet section and then flows out from the air outlet section, thus forming a blowing airflow.
[0050] From the above technical solution, it can be seen that the garden blower device described in the embodiment of the present application is provided with a housing 11, an airflow generating mechanism 19, and a grip mechanism 26. The grip housing 28, support tube 29, air inlet section, and air outlet section are arranged in sequence in the longitudinal direction. The extension direction of the grip is consistent with the longitudinal direction. This effectively reduces the radial volume of the garden blower device, minimizing its radial volume. This reduces the space occupied and improves operational flexibility and convenience. Furthermore, safety regulations for garden blowers require that the distance between the user's grip and the air outlet 31 be greater than 700 mm. However, if the air duct 18 is too long, the air outlet efficiency will be reduced. Therefore, when the air duct 18 is of optimal length, the grip housing 28 is positioned at the rear and the support tube 29 is used to extend the length to ensure the 700 mm design requirement.
[0051] In this embodiment, if Figure 1 As shown, the shell 11 is in the shape of a hollow rod as a whole. The hollow part forms a through passage 44. Of course, the shell 11 is not limited to being rod-shaped, and can also be in other shapes; for example, a cube shape, which is not specified in this application. The shell 11 includes an air duct 18. The air 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 longitudinally. Figure 1 As shown, the air duct 18 extends in the up-down direction. The air duct 18 is used for allowing air to pass through so that the air duct 18 can blow air outwards.
[0052] Furthermore, the housing 11 may include a casing 13, a blowpipe 15, and a siphon pipe 16 arranged in a longitudinal direction. The casing 13, blowpipe 15, and siphon pipe 16 are all hollow structures. The casing 13, blowpipe 15, and siphon pipe 16 are interconnected to form an air duct 18. The inner diameter of the casing 13 is larger than the inner diameter of the blowpipe 15. Thus, an airflow generating mechanism 19 can be installed in the casing 13. The inner diameter of the siphon pipe 16 is larger than the inner diameter of the blowpipe 15. Thus, when the airflow in the air duct 18 flows from the blowpipe 15 to the siphon pipe 16, the flow velocity can be increased, which is conducive to the airflow flowing out of the siphon pipe 16.
[0053] In this embodiment, the air duct 18 has two opposite ends in the longitudinal direction. Figure 1 As shown, the two ends are the upper end and the lower end of the air duct 18 respectively.
[0054] In this embodiment, the airflow generating mechanism 19 is provided in the air duct 18. Specifically, the airflow generating mechanism 19 can be fixedly provided in the air duct 18. The fixing method can be screw fixing, bolt fixing, etc., which is not specified in this application.
[0055] Furthermore, the airflow generating mechanism 19 can be disposed at any portion of the air duct 18. For example, the airflow generating mechanism 19 can be disposed between the two ends of the air duct 18. The airflow generating mechanism 19 can also be disposed within either end of the air duct 18. That is, the airflow generating mechanism 19 can be disposed within the upper end of the air duct 18. Alternatively, the airflow generating mechanism 19 can be disposed within the lower end of the air duct 18.
[0056] 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. Figure 1 As shown, the airflow generating mechanism 19 is disposed at the upper end of the air duct 18. Specifically, the housing 13 is located at the upper end. The airflow generating mechanism 19 is disposed in the housing 13.
[0057] 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 airflow generating mechanism 19 in the flow direction of the airflow. That is, the airflow generating mechanism 19 divides the air duct 18 into the air inlet section and the air outlet section. For example, Figure 1 As shown, the air inlet section is located above the air outlet section. This allows the air flow to flow from the air inlet section to the air outlet section and out from the air outlet section. For example, Figure 1 As shown, the airflow generating mechanism 19 can generate airflow in the air duct 18 and enable 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, an air inlet 33 is formed on the upper end of the air inlet section. An air outlet 31 is formed on the lower end of the air outlet section. The air outlet 31 is used to allow the airflow in the air duct 18 to pass through, so that the airflow can flow out of the air outlet section through the air outlet 31. Further, for example, Figure 1 As shown, 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.
[0058] 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 shell 11, thereby generating airflow in the air inlet section and making the airflow flow out from the lower end of the air outlet section to form blowing.
[0059] In this embodiment, the holding mechanism 26 is provided on the housing 11. Specifically, the holding mechanism 26 can be provided 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 can also be provided 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. Thus, the housing 11 can be held by holding the holding mechanism 26. The fixed connection can be a screw connection, a bolt connection, welding, an integral molding, etc., which is not specified in this application.
[0060] In this embodiment, the gripping mechanism 26 includes a gripping portion housing 28 and a support tube 29. One end of the support tube 29 is connected to the housing 11, and the other end of the support tube 29 opposite to the housing 11 is connected to the gripping portion housing 28. Specifically, Figure 1 As shown, the lower end of the support tube 29 is fixedly installed in the air duct 18. The upper end of the support tube 29 is connected to the handle housing 28. The connection method can be screw connection, bolt connection, welding, integral molding, etc. Thus, the handle housing 28 can be fixedly connected to the housing 11 through the support tube 29. More specifically, for example, Figure 1 As shown, the support tube 29 is fixedly installed in the upper end of the air inlet section. Further, the support tube 29 is fixedly installed in the housing 13. The fixing method can be interference fit, screw connection, welding, etc.
[0061] In this embodiment, the handle housing 28 is provided with a grip for the user to grasp. This allows the user to grip the grip to increase friction between the palm and the grip mechanism 26. Furthermore, the grip can be positioned away from the housing 11, keeping the airflow within the air duct 18 at a distance from the operator, thereby preventing the airflow from causing harm to the operator. Safety regulations for garden hair dryers require that the distance between the user's grip and the air outlet 31 be greater than 700 mm. However, if the air duct 18 is too long, the air outlet efficiency will be reduced. Therefore, when the air duct 18 is at an optimal length, the handle housing 28 is positioned at the rear, and a support tube 29 is used to extend the length to ensure the 700 mm design requirement.
[0062] In this embodiment, the handle housing 28, the support tube 29, the air inlet section and the air outlet section are arranged in sequence in the longitudinal direction. That is, the handle housing 28 is located at the end of the support tube 29 away from the air duct 18. The air inlet section is located between the support tube 29 and the air outlet section. For example, Figure 1 As shown, the handle housing 28 is located at the upper end of the support tube 29. Specifically, one end of the handle housing 28 facing the support tube 29 is sleeved on the outside of the support tube 29. Figure 1 As shown, the lower end of the grip housing 28 is sleeved onto the outer side of the upper end of the support tube 29 .
[0063] In this embodiment, the extending direction of the grip portion is consistent with the longitudinal extending direction. Thus, the extending direction of the grip portion is consistent with the extending direction of the air outlet section. Figure 1 As shown, the grip and air outlet section both extend in the vertical direction. This effectively reduces the radial volume of the garden hair dryer, minimizing its radial volume. This reduces space usage and improves operational flexibility and convenience.
[0064] In one embodiment, the handle 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 handle housing 28, the support tube 29, the air inlet section and the air outlet section are arranged in a straight line. For example, Figure 1 As shown, the handle shell 28 is located above the support tube 29. The support tube 29 is located above the air inlet section. The air inlet section is located above the air outlet section. Because the safety regulations of garden hair dryers require that the distance between the handle 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 handle shell 28, the support tube 29, the air inlet section and the air outlet section are arranged in a straight line, and the extension direction of the handle is consistent with the direction of longitudinal extension, so that the length and efficiency of the air duct 18 can be optimized. Specifically, the length of the air duct 18 can be made smaller to reduce the air outlet loss. The air inlet 33 and the air outlet 31 are in a straight line, the air flow direction remains basically unchanged, and the air flow loss is small.
[0065] In one embodiment, the central axes of the handle housing 28, the support tube 29, the air inlet section, and the air outlet section are substantially aligned, thereby further reducing the radial volume of the garden hair dryer and the space occupied by the garden hair dryer.
[0066] Furthermore, the center of the air outlet 31 is located on the central axis of the gripping mechanism 26. Rotating the gripping mechanism 26 can accurately control the position of the air outlet 31 of the air duct 18, thereby further making the operation more flexible, the rotation more convenient, and the working directionality better.
[0067] Specifically, the center of the air outlet 31 is located on the central axis of the air duct 18. More specifically, as Figure 1 As shown, the central axis of the housing 13, the central axis of the blowpipe 15 and the central axis of the siphon pipe 16 are all on the same straight line. The air outlet 31 is provided on the lower side of the siphon pipe 16.
[0068] 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 air flow direction remains basically unchanged, and the air flow loss is small. Figure 1 As shown, the central axis of the housing 13, the central axis of the blowpipe 15, and the central axis of the siphon 16 are all aligned. An air inlet 33 is provided on the upper side of the housing 13. Therefore, when the fan 21 creates a negative pressure within the air duct 18, air outside the housing 11 can flow into the air inlet section through the air inlet 33 and then flow along the extension direction of the air outlet section until it flows out of the air outlet 31.
[0069] Furthermore, the rotation axis of the fan 21 is located on the same straight line as the central axis of the air duct 18. Figure 1As shown, the fan 21 is located at the center of the housing 13. The fan 21 can rotate around the central axis of the housing 13. The central axis of the housing 13, the central axis of the blowpipe 15, and the central axis of the siphon 16 are all located on the same straight line.
[0070] Preferably, a first shock absorber 39 is disposed between the support tube 29 and the air duct 18. Specifically, the first shock absorber 39 is disposed between the support tube 29 and the air duct 18. This prevents impact between the support tube 29 and the inner wall of the air duct 18 when the housing 11 is moved using the gripping mechanism 26, thereby reducing wear on the housing 11. The first shock absorber 39 may be made of, for example, sponge, rubber, or foam.
[0071] Preferably, a second shock absorber 38 is disposed between the support tube 29 and the grip housing 28. Specifically, the second shock absorber 38 is disposed between the support tube 29 and the grip housing 28. This prevents impact between the support tube 29 and the inner wall of the grip housing 28 when the grip mechanism 26 moves the housing 11, thereby reducing wear on the grip mechanism 26. The second shock absorber 38 may be made of, for example, sponge, rubber, or foam.
[0072] Preferably, the support tube 29 is made of a metal material. Thus, the strength of the support tube 29 can be sufficiently large. The metal material can be, for example, iron, copper, aluminum, etc. Preferably, the support tube 29 is made of aluminum.
[0073] 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 longitudinal direction. Figure 1 As shown, the air inlet 33 is located on the upper side of the housing 13. The air outlet 31 is located on the lower side of the siphon tube 16. The air inlet 33 is open toward the upper side, while the air outlet 31 is open toward the lower side. The support tube 29 is inserted into the air inlet 33. This allows the handle housing 28 to be separated from the air inlet 33.
[0074] In one embodiment, Figure 1 As shown, the central axis of the grip mechanism 26 is aligned with the central axis of the air duct 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 aligned. Rotating the grip mechanism 26 thus accurately controls the position of the air outlet 31 of the air duct 18, further enhancing operational flexibility, rotational convenience, and operational directional control.
[0075] In another embodiment, the air inlet 33 is open downwards when the garden blower is in operation. Figure 2 As shown, the air inlet 33 opens downwards, thereby preventing the air inlet 33 from facing the operator, thus reducing the harm of the airflow to the operator.
[0076] Specifically, the housing 11 includes a first portion 35 close to the gripping mechanism 26 and a second portion 37 located on a side of the first portion 35 away from the gripping mechanism 26. Figure 2 As shown, the first portion 35 is located on the upper side of the housing 11. The second portion 37 is located on the lower side of the housing 11. The first portion 35 extends in the longitudinal direction. The second portion 37 extends in the longitudinal direction. The first portion 35 is located above the second portion 37. The first portion 35 and the second portion 37 are fixedly connected. The fixed connection can be screwed, bolted, welded, or integrally molded.
[0077] Furthermore, the air duct 18 is disposed in the second portion 37. The support tube 29 is passed through the first portion 35. Thus, the housing 11 can be connected to the gripping mechanism 26 through the first portion 35. The second portion 37 can generate airflow in the housing 11. Specifically, the airflow generating mechanism 19 is disposed in the second portion 37. For example, Figure 2 As shown, the airflow generating mechanism 19 is disposed on a side of the second portion 37 close to the first portion 35 . That is, the airflow generating mechanism 19 is disposed on the upper side of the second portion 37 .
[0078] Furthermore, the central axis of the first portion 35 does not coincide with the central axis of the second portion 37. That is, the central axis of the first portion 35 and the central axis of the second portion 37 are staggered in a direction perpendicular to the longitudinal extension.
[0079] Furthermore, an opening 32 is provided at one end of the first part 35 away from the second part 37, which is open in the direction of longitudinal extension facing away from the second part 37. The support tube 29 is passed through the opening 32. The air outlet 31 is provided at one end of the second part 37 away from the first part 35. And the air outlet 31 is open in the direction of longitudinal extension facing away from the first part 35. That is, the opening 32 and the air outlet 31 are relatively open in the direction of longitudinal extension. 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 provided at one end of the second part 37 facing the first part 35. For example, Figure 2 As shown, the air inlet 33 is provided at the upper end of the second portion 37. The air inlet 33 is opened in a direction offset from the longitudinal extension. Thus, when the hand is gripping the grip housing 28, the air inlet 33 is not directly facing the hand, thus preventing the airflow from causing harm to the user.
[0080] Furthermore, one 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 provided on the bent portion. Figure 2 As shown, the upper end of the second portion 37 forms a bent portion extending downward.
[0081] In one embodiment, the handle is located below the central axis of the airflow generating mechanism 19 when the garden hairdryer is in operation. This is because when the airflow generating mechanism 19 generates airflow, the airflow, after flowing out through the air outlet, generates a reaction force on the air duct 18. Since the handle is located below the central axis of the airflow generating mechanism 19 when the garden hairdryer is in operation, the force of the airflow on the air duct 18 can generate a torque causing the air duct 18 to rotate upward relative to the handle. This allows the air duct 18 to be lifted upward by the reaction force of the airflow, thereby saving manpower.
[0082] In one embodiment, the garden hair dryer provided in 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 supply; the battery pack connection interface 41 or the power plug interface is provided at the end of the gripping 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 gripping mechanism 26. For example, Figure 1 As shown, the battery pack connection port 41 or power socket is located at the upper end of the grip mechanism 26. The housing 11 is located at the lower end of the grip mechanism 26. This allows for a hand to grip between the battery pack connection port 41 or power socket and the housing 11. Furthermore, since the motor and fan, the major weight components, are located at the front end of the grip mechanism 26, and the torques exerted on the grip mechanism 26 by the battery pack or external power source and the airflow generating mechanism 19 are opposite, operation is easier and more flexible.
[0083] In one embodiment, the garden blower 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 supply for connecting to the power socket; the battery pack and the external power supply are both used to provide power to the airflow generating mechanism 19, thereby ensuring that the fan 21 in the airflow generating mechanism 19 can rotate.
[0084] Furthermore, the battery pack connection interface 41 or the power socket includes a housing. Figure 1 As shown, the housing is generally rectangular. Of course, the housing is not limited to a rectangular shape and can also have other shapes, such as a hexagonal shape. The housing is used to house a battery pack or an external power source. Specifically, a cavity is provided within the housing. The battery pack or external power source can be installed within this cavity.
[0085] Furthermore, a through passage 44 is provided in the gripping mechanism 26. Specifically, the through passage 44 includes a first through passage provided in the gripping portion housing 28 and a second through passage provided in the support tube 29. Figure 1As shown, the first through channel is located on the upper side. The second through channel is located on the lower side. The first through channel and the second through channel are connected. And the end of the first through channel away from the second through channel is connected to the cavity. For example, Figure 1 As shown, the upper end of the first through-channel is connected to the cavity. The end of the second through-channel away from the first through-channel is connected to the air duct 18. Figure 1 As shown, the lower end of the second through channel is connected to the air duct 18. The through channel 44 is used for a conductor to pass through, and the conductor is used to connect the battery pack or external power supply to the airflow generating mechanism 19. The material of the conductor can be, for example, metal. Of course, the conductor is not limited to metal, and can also be other materials, such as graphite, etc., which is not specified in this application. The conductor is used to connect the power supply and the fan 21 and the motor 23. Thus, through the wire, the power supply can be electrically connected to the fan 21 and the motor 23, and then provide power to the fan 21 and the motor 23. By passing the wire through the first through channel and the second through channel, the wire can be extended into the air duct 18, and then connected to the fan 21 and the motor 23 in the air duct 18.
[0086] In one embodiment, a control switch 46 is provided on a side of the gripping mechanism 26 near the housing 11. This allows the fingers to easily access the control switch 46 when the hand is gripping the gripping mechanism 26, making it convenient for the fingers to operate the control switch 46. 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 can be triggered by the user's finger to operate the airflow generating mechanism 19 when the user grips the device 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 and rotation direction of the fan 21. Furthermore, when the garden blower is in operation, the central axis of the air duct 18 forms an acute angle with the horizontal plane; and the hand is gripping the gripping mechanism 26, and the fingers can access the control switch 46.
[0087] Specifically, the control switch 46 can be a membrane switch or a light sensor switch.
[0088] In one embodiment, the garden hairdryer provided in the embodiments of the present application further includes a support mechanism disposed at the end of the grip housing 28 away from the support tube 29. For example, the support mechanism is disposed at the upper end of the grip mechanism 26. The support mechanism is used to support the hand. Thus, when the hand is gripping the grip mechanism 26, the support mechanism provides support, reducing the difficulty of operation.
[0089] See also Figure 3 and Figure 4One embodiment of the present application provides a garden hair dryer, which includes: a housing 11; an air duct 18; an airflow generating mechanism 19 disposed in the air duct 18; the airflow generating mechanism 19 is used to generate airflow; a battery pack connection interface 41 is used to connect to a battery pack; the battery pack provides power to the airflow generating mechanism 19; and a gripping mechanism 26 is disposed between the battery pack connection interface 41 and the housing 11, so that the battery pack connection interface 41, the gripping mechanism 26, and the housing 11 are arranged in sequence.
[0090] The above technical solution demonstrates that the garden hair dryer described in the embodiments of this application comprises a housing 11, an airflow generating mechanism 19, a battery pack connection interface 41, and a gripping mechanism 26. The gripping mechanism 26 is disposed between the battery pack connection interface 41 and the housing 11, such that the battery pack connection interface 41, gripping mechanism 26, and housing 11 are arranged in sequence. Because the motor, fan, and battery pack are the primary weight components, and the motor and fan are all located at one end of the gripping mechanism 26, while the battery pack is located at the other end, the torques exerted on the gripping mechanism 26 by the battery pack and airflow generating mechanism 19 are opposite, resulting in easier and more flexible operation.
[0091] In this embodiment, if Figure 3 、 Figure 4 As shown, the shell 11 is in the shape of a hollow rod as a whole. The hollow part forms a through passage 44. Of course, the shell 11 is not limited to being rod-shaped, and can also be in other shapes; for example, a cube shape, which is not specified in this application. The shell 11 includes an air duct 18. The air 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 longitudinally. Figure 3 As shown, the air duct 18 extends in the left-right direction. The air duct 18 is used for allowing air to pass through so that the air duct 18 can blow air outwards.
[0092] In this embodiment, the airflow generating mechanism 19 is provided in the air duct 18. Specifically, the airflow generating mechanism 19 can be fixedly provided in the air duct 18. The fixing method can be screw fixing, bolt fixing, etc., which is not specified in this application.
[0093] In this embodiment, the airflow generating mechanism 19 is used to generate airflow. Specifically, the airflow generating mechanism 19 includes a fan 21 and a motor 23 for driving the fan 21. When the fan 21 rotates, it creates a negative pressure within the air duct 18, allowing air to flow from outside the housing 11 into the air inlet section, thereby generating airflow within the air inlet section and outflowing from the right end of the air outlet section, forming a blowing airflow.
[0094] In this embodiment, the battery pack connection interface 41 is used to connect a battery pack. The battery pack provides power to the airflow generating mechanism 19. Therefore, when the battery pack is installed on the mounting interface, the torques exerted by the battery pack and the airflow generating mechanism 19 on the gripping mechanism 26 are opposite, making operation easier and more flexible.
[0095] Furthermore, the gripping mechanism 26 includes a gripping portion housing 28 and a support tube 29. One end of the support tube 29 is connected to the housing 11, and the other end of the support tube 29 opposite to the housing 11 is connected to the gripping portion housing 28. Specifically, for example, Figure 3 As shown, the right end of the support tube 29 is fixedly inserted into the air duct 18. The left end of the support tube 29 is connected to the handle housing 28. This connection can be made by screws, bolts, welding, or integral molding. Thus, the support tube 29 securely connects the handle housing 28 to the housing 11.
[0096] In this embodiment, the handle housing 28 is provided with a grip for the user to grasp. This allows the user to grip the grip to increase friction between the palm and the grip mechanism 26. Furthermore, the grip can be positioned away from the housing 11, keeping the airflow within the air duct 18 at a distance from the operator, thereby preventing the airflow from causing harm to the operator. Safety regulations for garden hair dryers require that the distance between the user's grip and the air outlet 31 be greater than 700 mm. However, if the air duct 18 is too long, the air outlet efficiency will be reduced. Therefore, when the air duct 18 is at an optimal length, the handle housing 28 is positioned at the rear, and a support tube 29 is used to extend the length to ensure the 700 mm design requirement.
[0097] In this embodiment, the handle housing 28, the support tube 29, the air inlet section and the air outlet section are arranged in sequence in the longitudinal direction. That is, the handle housing 28 is located at the end of the support tube 29 away from the air duct 18. The air inlet section is located between the support tube 29 and the air outlet section. For example, Figure 3 As shown, the handle housing 28 is located at the left end of the support tube 29. Specifically, one end of the handle housing 28 facing the support tube 29 is sleeved outside the support tube 29. Figure 1 As shown, the lower end of the grip housing 28 is sleeved onto the outer side of the upper end of the support tube 29 .
[0098] In this embodiment, the extending direction of the grip portion is consistent with the longitudinal extending direction. Thus, the extending direction of the grip portion is consistent with the extending direction of the air outlet section. Figure 3 As shown, the grip and air outlet section both extend in the left-right direction. This effectively reduces the radial volume of the garden hair dryer, minimizing its radial volume. This reduces space usage and improves operational flexibility and convenience.
[0099] In one embodiment, the handle 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 handle housing 28, the support tube 29, the air inlet section and the air outlet section are arranged in a straight line. For example, Figure 3 As shown, the handle shell 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 inlet section. The air inlet section is located at the left end of the air outlet section. Since the safety regulations of the garden hair dryer require that the distance between the handle 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 handle shell 28, the support tube 29, the air inlet section and the air outlet section are arranged in a straight line, and the extension direction of the handle is consistent with the longitudinal extension direction, so that the length and efficiency of the air duct 18 can be optimized. Specifically, the length of the air duct 18 can be made smaller to reduce the air outlet loss. The air inlet 33 and the air outlet 31 are in a straight line, the air flow direction remains basically unchanged, and the air flow loss is small.
[0100] In one embodiment, the central axes of the handle housing 28, the support tube 29, the air inlet section, and the air outlet section are substantially aligned, thereby further reducing the radial volume of the garden hair dryer and the space occupied by the garden hair dryer.
[0101] In one embodiment, the handle is located below the central axis of the airflow generating mechanism 19 when the garden hairdryer is in operation. This is because when the airflow generating mechanism 19 generates airflow, the airflow, after flowing out through the air outlet, generates a reaction force on the air duct 18. Since the handle is located below the central axis of the airflow generating mechanism 19 when the garden hairdryer is in operation, the force of the airflow on the air duct 18 can generate a torque that causes the air duct 18 to rotate upward relative to the handle. This allows the air duct 18 to be lifted upward by the reaction force of the airflow, thereby saving manpower. When the garden hairdryer is in operation, the central axis of the air duct 18 forms an acute angle with the horizontal plane.
[0102] In one embodiment, the support tube 29 is bent, and when the garden blower 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 handle housing 28 are not at the same height. Figure 3 As shown, the garden blower is placed horizontally. The handle housing 28 extends in the left-right direction. The support pipe 29 extends upward at an angle, thereby connecting the handle housing 28 to the air duct 18. The right end of the support pipe 29 is connected to the housing. The left end of the support pipe 29 is connected to the handle housing 28. The right end of the support pipe 29 is higher than the left end of the support pipe 29. Figure 4As shown, the garden blower is positioned horizontally. The handle housing 28 extends upward at an angle. A support tube 29 extends upward at an angle, connecting the handle housing 28 to 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 handle housing 28. The right end of the support tube 29 is higher than the left end.
[0103] Furthermore, the central axis of the grip portion is substantially parallel to the central axis of the airflow generating mechanism 19. Figure 3 As shown, 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.
[0104] In another embodiment, the grip portion is arranged at an angle to the central axis of the airflow generating mechanism 19. Specifically, for example Figure 4 As shown, the grip extends upward at an angle. 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 generates a reaction force on the air duct 18. Furthermore, since the grip is located below the airflow generating mechanism 19 when the garden blower is in operation, the force of the airflow on the air duct 18 can generate a torque causing the air duct 18 to rotate upward relative to the grip. This allows the air duct 18 to be lifted upward by the reaction force of the airflow, thereby saving manpower.
[0105] Furthermore, a control switch 46 is provided on one side of the gripping mechanism 26 near the housing 11. This allows the fingers to easily access the control switch 46 when the hand is gripping the gripping mechanism 26, making it convenient for the fingers to operate the control switch 46. 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 can be triggered by the user's finger to operate the airflow generating mechanism 19 when the user grips the device 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 and rotation direction of the fan 21. Furthermore, when the garden blower is in operation, the central axis of the air duct 18 forms an acute angle with the horizontal plane; and the hand is gripping the gripping mechanism 26, and the fingers can access the control switch 46.
[0106] Furthermore, the garden hairdryer of the embodiment of the present application further includes a support mechanism disposed at the end of the grip housing 28 away from the support tube 29. The support mechanism is used to support the hand. Thus, when the hand is gripping the grip mechanism 26, the support mechanism can provide support, reducing the difficulty of operation.
[0107] Preferably, the support tube 29 is made of a metal material. Thus, the strength of the support tube 29 can be sufficiently large. The metal material can be, for example, iron, copper, aluminum, etc. Preferably, the support tube 29 is made of aluminum.
