Description

Technical Field

[0001] This application relates to storm guns, and more particularly to handheld storm guns. Background Technology

[0002] A blower gun is a high-performance air-blowing device, also known as a powerful blower, leaf blower, dust collector, or air blower. Due to its superior performance in industrial dust removal, household cleaning, and leaf (snow) clearing, blower guns are increasingly used in daily life. Handheld blower guns are even more widely used due to their lightweight design and ease of operation.

[0003] Currently, when using a handheld storm gun, the angle of the airflow is adjusted by changing the position of the user's hand. The user's hand moves with the change of the airflow angle. At certain angles, the user's hand is sometimes in a relatively static position while holding the storm gun, which is very physically demanding. Utility Model Content

[0004] The present invention aims to provide a storm gun that can solve the above-mentioned problems.

[0005] According to a first aspect of the present invention, a storm gun is provided, comprising: The handle is designed for easy gripping by the user. The air duct section, which is connected to the handle section, is used to provide airflow to the outside; The power supply unit is used to provide power to the storm gun; The feature is that the storm gun further includes a pitch angle adjustment mechanism located between the handle and the blower section, which is capable of adjusting the pitch angle of the blower section relative to the handle.

[0006] According to one embodiment of the present invention, the pitch angle adjustment mechanism includes: a pitch button for locking and unlocking the pitch angle of the blower section relative to the handle section; and / or a limiting structure for preventing the blower section from pitching beyond the pitch range relative to the handle section.

[0007] According to one embodiment of the present invention, the pitch angle adjustment mechanism includes a pitch button with an external gear, an internal gear ring meshing with the external gear, and a return spring capable of pushing the pitch button to move axially.

[0008] According to one embodiment of the present invention, the pitch angle of the blower portion relative to the handle portion is in the range of -15° to +30°.

[0009] According to one embodiment of the present invention, the interior of the air duct is provided with sound-absorbing material; and / or the front of the air duct is provided with a soft sleeve device.

[0010] According to one embodiment of the present invention, the storm gun has a stepless speed control switch that can steplessly adjust the wind speed and a locking key to lock the wind speed.

[0011] According to one embodiment of the present invention, the locking key is disposed adjacent to the continuously variable speed switch.

[0012] According to one embodiment of the present invention, the storm gun has a storm start switch that can activate the storm mode with one button.

[0013] According to one embodiment of this utility model, a protective net is provided at the front and / or rear of the air duct, and the protective net is at least 60mm away from the blades of the storm gun. The distance can optionally be set to 70mm, 80mm, 90mm, 100mm, etc.

[0014] According to one embodiment of the present invention, the storm gun is a handheld storm gun.

[0015] According to this utility model, the storm gun can adjust the pitch angle of the air tube relative to the handle. Therefore, at some special angles, it is only necessary to adjust the pitch angle of the air tube through the pitch angle adjustment mechanism, instead of having the user's hand in a relatively stiff position to hold the storm gun. This saves physical strength and improves the user's operating experience. Attached Figure Description

However, it should be understood that the drawings are merely illustrative and for purposes of explanation only, and are not intended to limit the scope of the invention. Detailed Implementation

[0025] Figure 1 and Figure 2 A perspective view and a front view of the blower barrel of a storm gun according to a disclosed embodiment at a first angle relative to the handle are shown, respectively. Figure 3 and Figure 4 The illustration shows a perspective view and a front view of a storm gun with its blower section at a second angle relative to the handle section, according to a disclosed embodiment.

[0026] Depend on Figures 1-4 As can be seen, the storm gun 100 according to this disclosure includes a blower section 20, a handle section 10 pivotally connected to the blower section 20, and a battery module 60 connected to the handle section 10. A pitch angle adjustment mechanism 30 is provided at the junction of the blower section 20 and the handle section 10 for adjusting the angle between the blower section 20 and the handle section 10, allowing the user to adjust the pitch angle of the blower section 20 according to different tasks and workspaces. For example, when blowing away fallen leaves or snow in a garden, the blower section 20 can be tilted upwards relative to the handle section 10; for example, when cleaning a roof, the blower section 20 can be tilted downwards relative to the handle section 10, thus providing the user with a good operating experience.

[0027] exist Figure 1 and Figure 2 In the middle, the blower section 20 and the grip section 10 of the storm gun 100 are at a first angle, that is, they are perpendicular to each other.

[0028] exist Figure 3 and Figure 4 In the middle, the blower section 20 of the storm gun 100 and the handle section 10 are at a second angle, that is, the blower section 20 is tilted upward at a certain angle relative to the handle section 10.

[0029] Figure 5 , Figure 6 and Figure 7An exploded view schematically illustrates the pitch angle adjustment mechanism 30 between the air intake and the grip of a storm gun according to one disclosed embodiment. Figures 5-7 As can be seen, the pitch angle adjustment mechanism 30 includes an end cap 140 located at one end of the handle portion 10 near the air duct portion 20. An internal gear ring 170 is provided inside the end cap 140. The internal gear ring 170 can be integrally formed with the end cap 140 or can be fixedly attached to the end cap 140.

[0030] The pitch angle adjustment mechanism 30 also includes a housing portion 160 disposed at one end of the air duct portion 20 near the handle portion 10. A pitch button 180 and a cooperating return spring 150 are installed within the housing portion 160. The main body of the pitch button 180 is a closed-end cylindrical shape forming a chamber to accommodate the return spring 150. A circumferential external gear 130 that meshes with an internal gear ring 170 is provided at the closed end of the main body, and a cylindrical protrusion 190 coaxial with the axis of the cylindrical main body is provided at the closed end, facilitating user pressing to control the locking and unlocking of the pitch angle adjustment mechanism. According to one embodiment of this disclosure, the diameter of the cylindrical protrusion 190 is smaller than the diameter of the cylindrical main body. The external gear 130 is coaxial with the central axis of the cylindrical main body. A plurality of slits 185 extending along the axial direction are provided on the cylindrical wall of the main body. According to one embodiment of this disclosure, the number of slits 185 is six. Understandably, slit 185 can be any other suitable number, such as any number between 5 and 12.

[0031] The housing portion 160 is provided with a plurality of ribs 165 integral with the housing portion 160. The number of ribs 165 is the same as the number of slits 185. The ribs 165 engage with the slits 185, so that the gear button 180 is rotatably fixed to the air duct portion 20. That is, the gear button 180 cannot rotate relative to the air duct portion 20.

[0032] The reset spring 150 is placed in the cavity of the cylindrical body, and the pitch button 180 moves axially by means of the deformation of the reset spring 150, which may be a helical spring.

[0033] When it is necessary to adjust the pitch angle of the air duct section 20, the user presses the pitch button 180, and the pitch button 180 compresses the return spring 150 axially. Figure 6 The external gear 130 is moved axially to the right to disengage from the internal gear ring 170 (i.e., unlock). Once disengaged, the air duct portion 20 can rotate relative to the handle portion 10. After rotating to an appropriate angle, such as 15°, the user can release the tilt button 180, at which point the return spring 150 pushes the external gear 130 back towards the handle portion 10. Figure 6Pushing the left side of the device causes the external gear 130 to mesh with the internal gear ring 170 (i.e., lock). At this time, the blower section 20 is locked relative to the handle section 10, allowing it to operate normally, such as blowing away leaves.

[0034] According to one embodiment of this disclosure, the external gear 130 and the internal gear ring 170 of the pitch button 180 each have 24 teeth in the circumferential direction. That is, each rotation of one tooth corresponds to a rotation angle of 15°. It can be understood that the external gear 130 and the internal gear ring 170 can have any other suitable number of teeth in the circumferential direction, that is, each tooth can correspond to any suitable angle. Generally, the external gear 130 and the internal gear ring 170 can have any number of teeth between 20 and 60 in the circumferential direction.

[0035] Alternatively, the pitch angle adjustment mechanism 30 may include an internal gear ring disposed in the housing portion 160 and a pitch button 180 and a return spring 150 mounted in the end cover portion 140.

[0036] According to the storm gun disclosed herein, the pitch angle of the blower section 20 relative to the grip section 10 is optionally in the range of -30° to +45°, preferably in the range of -15° to +30°. In this document, a negative angle (e.g., -30°) indicates that the blower section 20 is tilted downwards relative to the grip section 10, and a positive angle (e.g., +45°) indicates that the blower section 20 is tilted upwards relative to the grip section 10.

[0037] According to one embodiment of this disclosure, the pitch angle adjustment mechanism 30 of the storm gun 10 is provided with a limiting structure to prevent the air tube portion 20 from pitching out of range relative to the handle portion 10.

[0038] According to another embodiment, the pitch angle adjustment mechanism 30 does not have an external gear and an internal gear ring structure, but has a rotating shaft that rotates the air duct portion 20 relative to the handle portion 10, the rotating shaft being able to lock the air duct portion 20 relative to the handle portion 10 in one or more rotatable positions.

[0039] The storm gun 100 disclosed herein includes a continuously variable speed control mechanism that can steplessly adjust the wind speed, allowing the user to adjust the wind speed from slow to fast or from fast to slow as needed. The continuously variable speed control mechanism can be a mechanical or electronic mechanism.

[0040] Figures 1-4The stepless speed control switch 50 of the storm gun according to this disclosure is shown. Stepless speed adjustment is possible by pressing the stepless speed control switch 50, and the wind speed can be locked using the lock button 80. In the storm gun according to this disclosure, the lock button 80 is located near the stepless speed control switch 50. That is, the lock button 80 is located adjacent to the stepless speed control switch 50, allowing the user to lock the desired wind speed with their thumb while controlling the stepless speed control switch with their index finger.

[0041] Figure 3 The present disclosure also shows a storm start switch 70, which can activate the storm mode with one click when the storm start switch 70 is pressed, thus improving work efficiency.

[0042] like Figures 1 to 4 As shown, the front of the air duct section 20 of the storm gun 100 disclosed herein is provided with a soft sleeve device 230. According to this disclosure, the soft sleeve device 230 can be a leather sleeve, rubber sleeve, plastic sleeve, etc., fixed to the front of the air duct section 20 by means of sleeve connection, snap-fit, adhesive bonding, etc. The soft sleeve device 230 serves two purposes: firstly, it prevents injury to a person accidentally colliding with the front of the storm gun; secondly, it acts as a buffer when the front of the storm gun collides with a hard object (such as the ground), thus protecting the storm gun.

[0043] According to this disclosure, a protective net is provided at the front and / or rear of the air duct section 20 of the storm gun 100. Figure 1 The protective net 40 at the rear of the blower section 20 is shown. According to one embodiment of this disclosure, the protective net is at least 60 mm away from the blades of the blower, preferably at least 90 mm away. Because the protective net 40 is provided, personal safety is prevented from being harmed by the inhalation of hair or other debris during use.

[0044] Figure 8 A schematic diagram of a silencer for a storm gun according to one disclosed embodiment is shown. Figure 8 As shown, the motor 90 is housed within the air duct section 20. A noise reduction device is provided on the inner wall of the air duct section near the motor 90. In the storm gun 100 according to this disclosure, the noise reduction device can be a noise reduction material 200 (e.g., noise-reducing cotton), thereby significantly reducing noise during the operation of the storm gun and improving the user's operating experience. In the storm gun 100 according to this disclosure, noise reduction material 200 is provided on both the front and rear sides of the motor 90. That is, noise reduction material 200 is provided at both the air inlet and outlet positions of the air duct section 20.

[0045] According to one embodiment, the sound-absorbing material 200 can be fixed to the inner wall of the duct section 20 by a fixing device. The fixing device is, for example, tape (single-sided or double-sided tape) or adhesive.

[0046] According to another embodiment of this disclosure, the duct section 20 may adopt a double-shell design, with a sound-absorbing material layer filled between the two shells to block noise transmission.

[0047] Optionally, sound-absorbing materials can be installed between the double-layer shell and on the inner wall of the air duct.

[0048] The battery module 60 can be fixedly or detachably connected to the handle 10 to provide power to the motor of the storm gun 100. Alternatively, the storm gun 100 can be directly powered by a power outlet by connecting it directly to a power outlet via a power cord.

[0049] According to the present invention, since the pitch angle of the blower section 20 relative to the handle section 10 can be adjusted, at some special angles, it is only necessary to adjust the pitch angle of the blower section 20 through the pitch angle adjustment mechanism, so that the user's hand does not need to be in a relatively stiff state to hold the blower, thereby saving physical strength and improving the user's operating experience.

[0050] Although the features of the embodiments described herein have been described, it will be understood that those skilled in the art can make various omissions, substitutions and changes to the structure of the present invention, and adjustments to the structure of the present invention are possible while still achieving the functions of the present invention.
