[0028] refer to Figure 1-4 .

[0029] In this specific embodiment, a dustproof and energy-saving blower is provided, comprising a housing 1, a blower 2 and a motor 3;

[0030] The housing 1 has an internal accommodation space, and a housing air filter inlet 11 and a housing air outlet 12 are provided on the housing 1; the blower 2 is arranged in the housing 1, and the blower 2 is fixedly connected to the housing 1, and the blower 2 is connected to the air outlet 12; the motor 3 is arranged in the housing 1, and the motor 3 is also connected to the blower 2. The accommodation space inside the housing 1 provides an environment isolated from the external environment for the blower 2 and the motor 3. The blower 2 and the motor 3 are installed inside the housing 1, and the dust, water vapor and other potentially corrosive particles in the environment outside the housing 1 are difficult to directly contact the blower 2 and the motor 3. The blower 2 and the motor 3 can work in a relatively closed and cleaner environment isolated from the external environment, and the probability of circuit failure caused by contact with water vapor, device moisture and rust, etc. is reduced, and the probability of device corrosion caused by contact with dust or other corrosive particles is also greatly reduced.

[0031] In this specific embodiment, a filter 4 is also included; the filter 4 is arranged outside the housing 1 and fixedly connected to the housing 1, and the filter 4 is connected to the housing air filter inlet 11, and the air in the external environment penetrates the filter 4 and enters the housing 1 through the housing air filter inlet 11. After the air containing dust, water vapor and other corrosive particles in the external environment is filtered by the filter 4 and enters the internal accommodation space of the housing 1, it is sent out from the housing air outlet 12 under the drive of the blower 2. During the whole air supply process, the motor 3 and the blower 2 are in a relatively dry and clean air flow environment, and the possibility of the motor 3 and the blower 2 being damp, rusted or corroded, and the possibility of structural aging and component damage is greatly reduced, and the whole blower can maintain stable operation for a longer time and obtain a longer working life.

[0032] In this specific embodiment, the shell 1 includes a front shell 1A and a rear cover 1B, which are detachably connected. The front shell 1A is roughly square and has an internal accommodating space, one of which is open for installing the rear cover 1B. The rear cover 1B is in a plate shape, and the shell air filter inlet 11 and the shell air outlet 12 are both opened on the rear cover 1B.

[0033] In this specific embodiment, the motor 3 is a brushless DC synchronous motor. Compared with the prior art that uses a low-speed, low-efficiency AC asynchronous motor to drive a heavy cast iron impeller, the dust-proof and energy-saving blower provided in this specific embodiment is equipped with a brushless DC synchronous motor with a larger speed and higher efficiency, which is compatible with the blower 2 and improves the energy efficiency of the motor 3.

[0034] In this specific embodiment, the blower 2 includes a blower support 21 and a blower 22; the blower support 21 is a plate-like structure, and the bottom of the blower support 21 is fixedly connected to the housing 1, and the blower 22 is fixedly connected to one side of the blower support 21. The blower 22 includes a volute 221 and an aluminum alloy riveted impeller 222; specifically, one side of the volute 221 is fixedly arranged on the blower support 21, the aluminum alloy riveted impeller 222 is arranged in the volute 221, and the aluminum alloy riveted impeller 222 is rotatably connected to the volute 221; the motor 3 is fixedly arranged on the outside of one side of the volute 221, and the motor 3 output shaft of the motor 3 passes through the volute 221 and is drivingly connected to the aluminum alloy riveted impeller 222. The volute 221 is provided with a volute air inlet 221A and a volute air outlet 221B for allowing air to enter, and the fan support 21 is provided with a support vent 21A, the volute air inlet 221A is aligned with the support vent 21A; the volute air outlet 221B is connected to the shell air outlet 12. The volute 221 is arranged on one side of the fan support 21 close to the shell air filter inlet 11. After the motor 3 is started, the output shaft of the motor 3 transmits torque to the aluminum alloy riveted impeller 222, driving the aluminum alloy riveted impeller 222 to rotate. The rotating aluminum alloy riveted impeller 222 draws air into the volute 221 from the volute air inlet 221A, compresses the air and sends it out from the shell air outlet 12 through the volute air outlet 221B. The motor 3 drives the aluminum alloy riveted impeller 222 to rotate continuously, and the air outside the shell 1 is continuously passed through the filter 4 and enters the shell 1 from the shell air filter inlet 11, and then continuously flows into the volute air inlet 221A.

[0035] During the operation of the above-mentioned blower, the shell air filter inlet 11 of the shell 1 and the shell air outlet 12 are arranged on the same side wall of the shell 1, and the volute 221 is arranged on the side of the fan support 21 close to the shell air filter inlet 11, then the motor 3 arranged at the volute 221 is located on the side close to the shell air filter inlet 11, and the air in the external environment enters the shell 1 through the shell air filter inlet 11 and first flows through the motor 3 and the surface of the volute 221, and then bypasses the motor 3 and the volute 221 before reaching the volute air inlet 221A opened on the other side of the fan support 21, so that the air will continuously flow through the surface of the motor 3 and the volute 221, and the heat generated by the motor 3 during operation The heat accumulated on the vortex casing 221 is transferred to the air and finally dissipated from the shell outlet 12 with the air flow, which largely avoids the situation that the motor 3 is burned due to heat accumulation due to untimely heat dissipation during operation, and the inside of the shell 1 is fully, effectively and timely cooled; at the same time, since the aluminum alloy riveted impeller 222 is made of aluminum alloy, compared with the blades cast by cast iron in one piece in the prior art, the aluminum alloy riveted impeller 222 has a lighter weight, and the motor 3 does not need to bear excessive burden when driving the aluminum alloy riveted impeller 222. When the blower 2 provides the same air volume and the same wind speed, the motor 3 has lower energy consumption.

[0036] In this specific embodiment, at least one heat dissipation hole 221C is provided on one side of the volute 221 where the motor 3 is installed, and the heat dissipation hole 221C is adjacent to the outer peripheral surface of the motor 3, so that the wind passing through the heat dissipation hole 221C blows the outer peripheral surface of the motor 3. The aluminum alloy riveted impeller 222 generates significant heat during high-speed rotation, and the heat dissipation hole 221C provided on the volute 221 can provide an additional heat dissipation path for the aluminum alloy riveted impeller 222, thereby improving the heat dissipation performance of the aluminum alloy riveted impeller 222.

[0037] In this specific embodiment, there are four heat dissipation holes 221C, which surround the motor 3. Since the heat dissipation holes 221C are provided around the motor 3, the air passing through the heat dissipation holes 221C forms an airflow to flow over the surface of the motor 3, and the heat generated by the motor 3 when working is dissipated to the outside of the housing 1 along with the airflow.

[0038] In this specific embodiment, a controller 5 and an operation panel are also included. The operation panel is arranged on the outer surface of the housing 1, and the controller 5 is arranged inside the housing 1. The controller 5 is fixedly connected to the housing 1, and the controller 5 interacts with the motor 3. In the specific setting, the controller 5 can be arranged near the motor 3. In this way, on the one hand, the distance between the controller 5 and the motor 3 can be shortened, which is convenient for the connection and interaction between the two. On the other hand, the air duct design in the housing 1 as described above can be used to take away the heat generated at the controller 5 with the airflow flowing inside the housing 1, so as to provide timely and effective heat dissipation for the controller 5.

[0039] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
