Description

Technical Field

[0001] This utility model relates to the field of blower technology, and more specifically, to a mobile blower with a waterproof and moisture-proof structure. Background Technology

[0002] The blower uses the high-speed rotation of the impeller to throw out air, which is drawn in through the air inlet and discharged through the air outlet. Both the air inlet and the air outlet have structures to prevent foreign objects from entering the interior. The blower can be installed indoors or outdoors as needed.

[0003] A search revealed an existing patent (publication number: CN216044551 U) that discloses a highly practical outdoor waterproof blower structure. This structure includes a housing formed by a fixed assembly of an upper cover and a lower cover, an annular impeller, and a waterproof motor. The waterproof motor is installed on the inner wall of the housing, and a rotatable annular impeller is installed inside the housing. An integrally formed guide groove is formed on the front of the housing, and an integrally formed rainproof brim extends outward from the guide groove. A strap fastener is provided at the bottom of the rainproof brim. An air inlet is formed on the front of the housing, and an air outlet is formed on the side. The rainproof brim in this invention serves to shield rainwater, preventing it from being drawn into the housing, thereby increasing the service life of the annular impeller and the waterproof motor. The outward protrusion of the guide groove creates a gap between the rainproof brim and the upper cover, allowing rainwater to flow quickly down the guide groove, further enhancing rain protection and providing a secure installation for a specific purpose. The inventors discovered the following problems with the existing technology during the development of this invention:

[0004] Existing blowers operate in outdoor environments with complex and changeable weather conditions. Rainfall may be accompanied by different wind directions, and changes in wind direction can cause rainwater to fall from various angles. In heavy rain, rainwater can be blown laterally, making it easy for rainwater to directly enter the blower. This can affect the operation of the internal equipment of the motor. Furthermore, when humid air is drawn into the blower, if it encounters a low temperature, the water vapor can easily reach the dew point temperature and condense. The condensed water droplets can enter the impeller and damage components such as the motor and impeller.

[0005] Therefore, a mobile blower with a waterproof and moisture-proof structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mobile blower with a waterproof and moisture-proof structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mobile blower with a waterproof and moisture-proof structure, comprising a base, a blower body, a universal adjustment pipe and a resistance heating wire, wherein a fixing hole is provided on one side of the upper end of the base, the blower body is installed on the upper end of the base, an exhaust port is provided on the right side of the blower body, a filter screen is installed on one side of the inner cavity of the exhaust port, an installation pipe is provided on the right side of the exhaust port, and an air supply connection port is provided on the right side of the installation pipe;

[0008] The universal regulating tube is located on the right side of the air supply connection port. An air inlet is opened at the end of the universal regulating tube away from the air supply connection port. The resistance heating wire is located on the inner surface of the universal regulating tube. A motor is installed on the left side of the fan body. An exhaust port is opened at the output end of the fan body. A connecting flange is welded to the outer surface of the exhaust port.

[0009] Preferably, the outer surface of the exhaust port is provided with a threaded structure, and the mounting tube is inserted into the outer surface of the exhaust port and engages with the threaded structure to achieve fixation.

[0010] Preferably, the diameters of the mounting pipe and the air supply connection port are equal, and the mounting pipe is movably connected to the air supply connection port via a rotating shaft.

[0011] Preferably, the shape of the universal regulating pipe is arranged in several corrugated patterns, and the universal regulating pipe is bent at 90 degrees away from the air supply connection port. The bending angle of the universal regulating pipe is controlled to adjust the orientation of the air inlet.

[0012] Preferably, the resistance heating wire is spirally wound and fixed around the inner wall of the universal adjustment tube, and the output end of the motor is connected to the impeller inside the fan body.

[0013] Preferably, the fixing holes are provided in two sets, and the two sets of fixing holes are arranged symmetrically.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] As attached Figures 1 to 4 The mobile blower shown includes a waterproof and moisture-proof structure, comprising a base 1, a blower body 2, a universal adjustment pipe 7 and a resistance heating wire 9. A fixing hole 101 is provided on one side of the upper end of the base 1. The blower body 2 is installed on the upper end of the base 1. An exhaust port 3 is provided on the right side of the blower body 2. A filter screen 4 is installed on one side of the inner cavity of the exhaust port 3. An installation pipe 5 is provided on the right side of the exhaust port 3. An air supply connection port 6 is provided on the right side of the installation pipe 5.

[0025] The universal regulating pipe 7 is located on the right side of the air supply connection port 6. An air inlet 8 is opened at the end of the universal regulating pipe 7 away from the air supply connection port 6. The resistance heating wire 9 is located on the inner surface of the universal regulating pipe 7. A motor 10 is installed on the left side of the fan body 2. An exhaust port 11 is opened at the output end of the fan body 2. A connecting flange 12 is welded to the outer surface of the exhaust port 11.

[0026] Among them: the fixing hole 101 of the base 1 provides a stable and precise positioning point for the installation of the fan body 2. By using appropriate bolts or other fasteners to cooperate with the fixing hole 101, the fan body 2 can be firmly installed. The filter screen 4 plays a preliminary role in filtering impurities. During the process of the fan body 2 drawing air from the exhaust port 3 by the impeller driven by the motor 10, the filter screen 4 prevents impurities from entering the fan body 2. The mounting pipe 5 and the air supply connection port 6 provide a stable connection medium for the fan body 2. The mounting pipe 5 can be rotated to engage with the external thread 31 of the exhaust port 3 for connection and fixation. The universal adjustment pipe 7 can... The universal regulating pipe 7 can be flexibly bent and rotated in multiple directions. When facing different rainfall directions and environments, users can easily adjust the orientation of the air inlet 8 on the universal regulating pipe 7 according to the actual situation. The universal regulating pipe 7 is equipped with a resistance heating wire 9. When the resistance heating wire 9 is energized, it will generate heat and raise the temperature of the pipe wall. In humid environments, the air often contains a lot of water vapor. The resistance heating wire 9 ensures that the temperature of the pipe wall is always higher than the dew point temperature of the air, thereby effectively preventing water vapor from condensing on the pipe wall and preventing moisture from accumulating at the impeller exhaust port 3. The connecting flange 12 ensures that the exhaust port 11 can guarantee the sealing of the connection.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the outer surface of the exhaust port 3 is provided with a threaded structure 31. After the mounting tube 5 is inserted into the outer surface of the exhaust port 3, it engages with the threaded structure 31 to achieve fixation. Furthermore, the exhaust port 3 is connected and installed with the mounting tube 5 using a threaded structure, which makes the disassembly process relatively simple. Just align the mounting tube 5 with the exhaust port 3, and then rotate the mounting tube 5 to gradually insert it along the thread to complete the installation.

[0030] In a preferred embodiment, the diameters of the mounting pipe 5 and the air supply connection port 6 are equal, and the mounting pipe 5 is movably connected to the air supply connection port 6 via a rotating shaft; furthermore, the diameters of the mounting pipe 5 and the air supply connection port 6 ensure smooth airflow, and the mounting pipe 5 can rotate flexibly when engaged with the exhaust port 3 via the rotating shaft connection.

[0031] In a preferred embodiment, the universal regulating pipe 7 has a corrugated shape with several corrugations. The universal regulating pipe 7 is bent at 90 degrees away from the air supply connection port 6. The bending angle of the universal regulating pipe 7 is controlled to adjust the orientation of the air inlet 8. Furthermore, in rainy weather, rainwater will fall naturally under the action of gravity. Setting the air inlet 8 downward can effectively prevent rainwater from directly entering the pipe. The corrugated pipe structure can guide rainwater to slide down the pipe wall. Even if a small amount of rainwater splashes onto the pipe, it will flow to the ground along the grooves of the corrugations and will not accumulate at the pipe opening or flow into the exhaust port 3. Moreover, it can be bent by the user.

[0032] In a preferred embodiment, the resistance heating wire 9 is spirally wound around the inner wall of the universal regulating tube 7, and the output end of the motor 10 is connected to the impeller inside the fan body 2. Furthermore, the spiral wound of the resistance heating wire 9 around the inner wall of the universal regulating tube 7 can ensure that the air inside the tube is heated evenly. The spiral distribution allows heat to be evenly distributed in the circumferential direction of the tube, without obvious heating dead zones, and air molecules will be affected by heat when passing near the tube wall.

[0033] In a preferred embodiment, two sets of fixing holes 101 are provided, and the two sets of fixing holes 101 are symmetrically arranged; furthermore, the torque generated by the motor 10 can be efficiently transmitted to the impeller inside the fan body 2, so that the impeller can rotate at a high speed to draw air out from the exhaust port 3.

[0034] The working process of this utility model is as follows: First, when the blower is working, the motor 10 starts and its output end directly transmits power to the impeller inside the blower body 2, causing the impeller to rotate at high speed. The rotation of the impeller generates negative pressure inside the blower body 2. At this time, negative pressure is formed at the exhaust port 3. Under the action of the pressure difference, the outside air begins to flow towards the exhaust port 3. The air first gathers towards the air inlet 8 at the far end of the universal adjustment pipe 7. Since the universal adjustment pipe 7 is corrugated and can be bent and adjusted, the orientation of its air inlet 8 can be flexibly adjusted according to the corrugated pipe body and the actual direction of rainwater.

[0035] When it rains, rainwater will fall naturally under gravity. Positioning the air inlet 8 downwards effectively prevents rainwater from directly entering the pipe. After air enters the universal regulating pipe 7 through the air inlet 8, during its flow within the pipe, if the ambient humidity is high, the resistance heating wire 9 will be energized and heat up. Its spiral structure, wrapped around the inner wall of the universal regulating pipe 7, evenly heats the pipe wall, raising its temperature and maintaining it above the air dew point temperature. This effectively prevents moisture in the air from condensing into water droplets on the pipe wall, avoiding potential pipe blockage caused by moisture condensation and preventing humid air from entering the fan body 2 and causing corrosion to components such as the motor and impeller. Air then smoothly enters the exhaust port 3 through the installation pipe 5. Before entering the exhaust port 3, the air passes through the universal regulating pipe 7. The connection point with the air supply port 6 enters the installation pipe 5. The installation pipe 5 is fixed to the air outlet 3 by the threaded structure 31. When disassembly or installation is required, simply rotate the installation pipe 5. The air passes through the filter screen 4 installed on one side of the inner cavity of the air outlet 3. The filter screen 4 can intercept impurities. The treated air is discharged from the exhaust port 11 of the blower body 2 under the continuous suction of the impeller. The connecting flange 12 welded to the outside of the exhaust port 11 facilitates reliable connection with subsequent ventilation ducts or other related equipment. The fixing hole 101 of the base 1 provides a stable and precise positioning point for the installation of the blower body 2. The blower body 2 is installed on the required equipment by using appropriate bolts or other fasteners to cooperate with the fixing hole 101. The above is the working principle of this mobile blower with a waterproof and moisture-proof structure.
