Description

Portable blower adjustment structure

The present invention relates to a blower structure; in particular, to a portable blower adjustment structure that can adjust the exhaust outlet to any angle and can be carried and moved at any time and stably placed.

According to the general structure of the blower, it at least includes a hollow outer shell and a motor fan installed in the outer shell. The outer shell has a base plate for placing on the floor or table, an air inlet for the air outside the outer shell to flow into the outer shell, and an air outlet for discharging the air that has flowed into the inner shell toward the other side of the outer shell. In this way, the circulation effect of exhaust and extraction can be achieved;

Although the above creation can achieve its creation purpose, it will produce the following deficiencies during operation:

Since the base of the conventional blower is fixed to the bottom of the housing, the blower can be placed on the floor or table. However, during the moving process, both hands must be used to move the blower to another place, which causes inconvenience in moving and is a major problem.

As mentioned above, since the base plate of the conventional blower is fixed to the bottom surface of the outer shell, the angle between the base plate and the exhaust outlet of the blower is also fixed, so that the wind force sucked out will only spray at a fixed angle, and the discharged wind force will be forced to directly hit the machine equipment or the position where the personnel are working, resulting in failure to meet the actual needs of the parties, which is another major trouble.

Therefore, how to develop a device with stepless adjustment of the spray direction angle, which can be carried and moved with one hand and can be stably placed, is a technical issue that the industry needs to solve as a priority.

The main content of the portable blower adjustment structure of the present invention is to provide a method of using the shaft of the fixing part to be sleeved in the shaft hole of the handle support, so that the magnetic attraction part can be located between the fixing groove of the horizontal plate of the fixing part and the metal limit plate of the handle support, and one end of the fixing part is assembled at the blower body, so that the handle of the handle support is located above the blower body and the supporting part of the handle support. Under the blower body; in this way, it can not only maintain any angle adjustment between the fixing part and the handle support, but also has the function of changing the direction angle of the exhaust outlet of the blower body assembled at the fixing part, and has the function of steplessly adjusting the spray direction. At the same time, it can also be carried and moved with one hand, and the placement of the blower is more stable. Multiple functions are its progressiveness.

In order to achieve the above-mentioned purpose, the main technical means of the present invention at least include: a blower body, a fixing member arranged at the blower body, a handle support member arranged at the fixing member, and a magnetic attraction member located between the fixing member and the handle support member, wherein: the blower body at least includes a hollow outer shell, and a motor fan installed and assembled in the outer shell, the outer shell has an air inlet for air to flow in, and an air outlet for exhausting the air that has flowed into the inner part of the outer shell toward the other side of the body; the fixing member at least includes a magnetic attraction member arranged at the fixing member, and a magnetic attraction member located between the fixing member and the handle support member. The blower body comprises a fixing part, a horizontal plate connected to the other end of the fixing part, an axis arranged on the horizontal plate, a fixing groove arranged on the horizontal plate, and a control box with a key switch connected to the other end of the horizontal plate; the handle support component at least comprises a handle for hand-holding, a metal stop plate connected to the other end of the handle, a support component connected to the metal stop plate, and an axis hole for accommodating the axis of the fixing component; and the magnetic attraction component is accommodated in the fixing groove, and the other side of the magnetic attraction component can be attached and attracted to the outer surface of the metal stop plate.

The present invention is related to a portable blower adjustment structure, as shown in Figures 1 to 5, which at least includes: a blower body 1, a set of fixing parts 2 arranged at the blower body 1, a set of handle support parts 3 arranged at the fixing parts 2, and a magnetic attraction part 4 located between the fixing parts 2 and the handle support parts 3, wherein:

The blower body 1 at least includes a hollow outer shell 10 and a motor fan (not shown) installed in the outer shell 10. The outer shell 10 has an air inlet 101 for air to flow in, and an air outlet 102 for discharging the air that has flowed into the inner part of the outer shell 10 toward the other side of the outer shell 10;

The fixing member 2 at least includes a fixing portion 20 assembled at the blower body 1, horizontal plates 21, 22 connected to the other end of the fixing portion 20, shafts 210, 220 provided at the horizontal plates 21, 22, fixing grooves 211, 221 provided at the horizontal plates 21, 22, and a control box 25 having a key switch 251 connected to the other end of the horizontal plates 21, 22;

The handle support member 3 at least includes a handle portion 30 for hand-holding, a metal stop plate 31 connected to the other end of the handle portion 30, support portions 32, 33 connected to the metal stop plate 31, and an axis hole 310 for accommodating the axis portions 210, 220 of the fixing member 2; the handle portion 30 and the support portions 32, 33 respectively form an opening and closing angle of about 120 to 160 degrees;

The magnetic attraction member 4 is accommodated in the fixing grooves 211 and 221, and the other side of the magnetic attraction member 4 can be attached to and attracted to the outer surface of the metal limiting plate 31;

Please refer to Figures 1 and 3. When the user wants to move the blower body 1, he only needs to hold the handle portion 30 of the handle support member 3 with one hand, and then use one hand to move the blower body 1 (including the fixing member 2 and the handle support member 3) to the desired working place. Then, the handle portion 30 of the handle support member 3 and the support portions 32 and 33 are respectively opened and closed at an angle of about 120 to 160 degrees, so that the blower body 1 can be placed When the fan is placed on the ground or on a table, it will be in a more stable state; at this time, the key switch 251 located at the control box 25 can be pressed to start the motor fan located in the blower body 1, and the air located outside the air inlet 101 will be sucked into the outer shell 10 by the air inlet 101, and then squeezed and ejected from the exhaust outlet 102 of the outer shell 10 toward the other side of the outer shell 10 (as shown in Figure 3) At this time, if the working space is too narrow or the equipment is too densely placed or too close to the workers, one can use one hand to press or hold the handle 30 and then use the other hand to apply force to move the exhaust outlet 102 of the blower body 1 to move it upward or downward (that is, the force must be greater than the magnetic attraction of the magnetic element 4) to the desired angle and then stop (as shown in Figure 4). At this time, the magnetic element 4 that has been adjusted and rotated will continue to adhere to the The outer surface of the metal limit plate 31 (i.e., the magnetic attraction force of the magnetic attraction member 4 will be greater than the moment formed by the gravity at one end of the blower body 1) is adjusted to achieve the adjusted angle positioning; in this way, the fixing member 2 and the handle support member 3 can be adjusted at any angle, and the exhaust outlet 102 of the blower body 1 assembled at the fixing member 2 can be linked to change the spray angle, thereby achieving the effect of stepless adjustment of the spray direction.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention; therefore, all equivalent changes or modifications based on the features and spirit described in the scope of the present invention should be included in the scope of the patent application of the present invention.
