Description

Technical Field

[0001] The present invention relates to a high-pressure wind blade. Background Art

[0002] At present, in the production processes of many industries, high-pressure pumps are required, such as water heaters, air pumps, fans, high-efficiency radiators, etc. Existing high-pressure pumps all adopt a structure similar to that of fan blades. The difference is that the inclination angle of the blades of the high-pressure pump is larger, which can generate a greater wind pressure and flow rate. However, for the wind blades of such high-pressure pumps, the area of the air inlet side is equal to the area of the air outlet side, and the pressure of the blown air is still not high enough. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a high-pressure wind blade with a simple structure and capable of generating an ultra-high wind pressure.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] A high-pressure wind blade includes a main shaft and a plurality of blades spaced apart on the main shaft. The blades include an inner air-throwing section and an outer air-pressing section. The main shaft is connected with a baffle plate located on the air outlet side of the blades, and the outer edge of the baffle plate is located between the main shaft and the outer edge of the blades.

[0006] Preferably, the inner air-throwing section is parallel to the axis of the main shaft, and the outer air-pressing section is an inclined arc plate.

[0007] Preferably, the inner air-throwing section is an arc plate parallel to the main shaft. The rotation direction when the high-pressure wind blade normally presses air is the rotation direction of the blade, and the inner air-throwing section bends in a direction opposite to the rotation direction of the blade.

[0008] Preferably, the outer air-pressing section bends towards the rotation direction of the blade relative to the inner air-throwing section, so that a bending part is formed at the connection between the outer air-pressing section and the inner air-throwing section.

[0009] Preferably, the high-pressure wind blade further includes an air-gathering ring. The main shaft and the blades are both arranged inside the air-gathering ring, and the outer ends of at least two blades are fixedly connected to the inner side wall of the air-gathering ring.

[0010] Preferably, the outer ends of all the blades are fixedly connected to the inner side wall of the air-gathering ring.

[0011] Preferably, the baffle plate is circular and the outer edge of the baffle plate is flush with the outer edge of the inner air-throwing section.

[0012] The beneficial effects of the present invention are as follows: The high-pressure wind blade of the present invention has a simple structure and is easy to manufacture. When it rotates, the cross-sectional area of the air outlet position is smaller than that of the air inlet position, and it can compress air to generate extremely high wind pressure.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings.

[0017] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, the descriptions involving "preferred", "sub-preferred", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one of such features.

[0018] Referring to Figures 1 to 3 , the present invention provides a high-pressure wind blade, which includes a main shaft 1 and a plurality of blades 2 spaced apart on the main shaft 1. Each blade 2 is evenly arranged along the outer wall of the main shaft 1. The blade 2 includes an inner air-throwing section 21 and an outer air-compressing section 22. The main shaft 1 is connected with a baffle 3 located on the air outlet side of the blade 2, and the outer edge of the baffle 3 is located between the outer edges of the main shaft 1 and the blade 2.

[0019] Preferably, the baffle 3 is circular and the outer edge of the baffle 3 is flush with the outer edge of the inner air-throwing section 21.

[0020] The inner air-throwing section 21 is parallel to the axis of the main shaft 1, and the outer air-compressing section 22 is an inclined arc-shaped plate. Referring to Figure 2, a pressure accumulation chamber 5 is formed between two adjacent blades 2 and the baffle 3. When the high-pressure wind blade of the invention rotates counterclockwise during operation, the air directly in front of the outer air-pressing section 22 is directly pressed by the outer air-pressing section 22 to the rear of the blade 2; the air in front of the inner air-throwing section 21 is first sucked into the pressure accumulation chamber 5. Due to the principle that the faster the speed, the lower the air pressure, the air in the pressure accumulation chamber 5 will flow outwards and is finally also pressed by the outer air-pressing section 22 to the rear of the blade 2. Since the air inlet area is larger than the air outlet area, therefore, when the high-pressure wind blade of the present invention rotates, it can compress the air and generate an ultra-high wind pressure.

[0021] Further, the inner air-throwing section 21 is an arc-shaped plate parallel to the main shaft 1. The rotation direction when the high-pressure wind blade normally presses air is the rotation direction of the blade 2, and the inner air-throwing section 21 bends towards the direction opposite to the rotation direction of the blade 2. With such a structure, it is convenient to throw the air in the pressure accumulation chamber 5 outwards along the centrifugal direction.

[0022] Further, the outer air-pressing section 22 bends towards the rotation direction of the blade 2 relative to the inner air-throwing section 21, so that a bending portion is formed at the connection between the outer air-pressing section 22 and the inner air-throwing section 21. With such a design of the outer air-pressing section 22, the pressure on the air thrown out from the pressure accumulation chamber 5 can be increased.

[0023] Refer to Figure 1 And Figure 2 , in Embodiment 1 of the present invention, the high-pressure wind blade further includes a cylindrical air-gathering ring 4. The main shaft 1 and the blade 2 are both arranged inside the air-gathering ring 4, and the outer ends of at least two blades 2 are fixedly connected to the inner side wall of the air-gathering ring 4. Preferably, the outer ends of all the blades 2 are fixedly connected to the inner side wall of the air-gathering ring 4. The design of the air-gathering ring 4 can further enhance the air-gathering pressure.

[0024] Refer to Figure 3 , in Embodiment 2 of the present invention, the high-pressure wind blade does not include the air-gathering ring 4, and it can be used in a pipeline slightly larger than the above-mentioned air-gathering ring 4. Compared with the solution with the air-gathering ring 4, the air-gathering pressure of this solution is slightly smaller, but the air-gathering flow rate will be increased.

[0025] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
