[0002] The blower, also known as a fan or air blower, plays a crucial role in a vehicle's air conditioning and heating system. When the vehicle is in air conditioning mode, the blower draws in outside air and guides it through the condenser and evaporator to cool or heat the interior space. Even when cooling or heating is not needed, the blower still provides ventilation.
[0003] In existing technologies, the impeller of a traditional automotive blower is directly fitted to the shaft, and the shaft end does not have a waterproof seal, causing the shaft end to be directly exposed to the air and in direct contact with the air drawn in from upstream. This structure often leads to problems such as shaft end corrosion, water accumulation in the blower, and poor airflow. Utility Model Content
[0004] The purpose of this utility model is to provide a blower structure with a sealed air guide cover to alleviate the technical problems existing in the prior art, such as the lack of a waterproof seal at the shaft end of the blower, which causes the shaft to directly contact the air drawn in from upstream, resulting in shaft end corrosion, water accumulation in the blower, and poor airflow.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] In a first aspect, the present invention provides a blower structure with a sealed flow guide cover, including an impeller mechanism and an end cover. The impeller mechanism includes a housing assembly and a blade assembly, and the blade assembly is connected to the housing assembly along the outer edge of the housing assembly.

[0008] Furthermore, the housing assembly includes a first housing and a connector, one end of the first housing is provided with the main shaft chamber, and the first housing is connected to the blade assembly through the connector;
[0009] The end cap is connected to the first housing to seal the spindle chamber.
[0010] Furthermore, a connecting block is provided at one end of the first housing;
[0011] The end cap is provided with a connecting groove;
[0012] The connecting block is connected to the connecting groove.
[0013] Furthermore, the end cap is welded to the first housing at the joint.
[0014] Furthermore, the connector is connected to the first housing along the outer edge of the first housing, and the connector is provided with a first guide surface, which is used to guide air to the blade assembly.
[0015] Furthermore, the outer wall of the end cap is configured as a second flow guide surface, which is aligned and connected to the end of the first flow guide surface that is away from the blade assembly.
[0016] Furthermore, the housing assembly also includes a plurality of reinforcing ribs, which are spaced apart along the outer wall of the first housing and are all connected to the connector.
[0017] Furthermore, the housing assembly also includes a second housing, which is connected to the end of the first housing remote from the end cap;

[0041] Example 1
[0042] This embodiment provides a blower structure with a sealed flow guide cover, see reference. Figure 1 and Figure 3 The blower structure with a sealed flow guide cover includes an impeller mechanism 1 and an end cover 2. The impeller mechanism 1 includes a housing assembly and a blade assembly 14. The blade assembly 14 is connected to the housing assembly along the outer edge of the housing assembly. The end cover 2 is connected to the housing assembly and is used to close the main shaft chamber of the housing assembly.
[0043] This utility model embodiment at least alleviates the technical problems existing in the prior art where the blower shaft end does not have a waterproof sealing function, resulting in shaft end corrosion, water accumulation in the blower, and poor airflow due to the shaft directly contacting the air drawn in from upstream.
[0044] In this embodiment of the present invention, the housing assembly of the impeller mechanism 1 is used to connect with an external rotating shaft, and a main shaft chamber connected to the rotating shaft is opened inside the housing assembly. The end of the main shaft chamber opposite to the shaft is in an open state. The end cover 2 is placed on the open end of the main shaft chamber of the housing assembly so that the shaft end has a waterproof sealing function, avoiding problems such as corrosion or poor flow due to direct contact between the shaft and the air after a period of use.
[0045] Compared with the prior art, the blower structure with a sealing guide cover provided in this utility model embodiment achieves the sealing of the main shaft chamber by setting an end cover 2 at the opening end of the main shaft chamber of the housing assembly, thereby avoiding water accumulation, corrosion and poor flow due to direct contact between the shaft and air.
[0046] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The housing assembly includes a first housing 11 and a connector 12. One end of the first housing 11 has a main shaft chamber, and the first housing 11 is connected to the blade assembly 14 through the connector 12.

[0061] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The blade assembly 14 includes a first connecting ring 142, a second connecting ring 143, and a plurality of blade bodies 141. The first connecting ring 142 is connected to the housing assembly. One end of each of the plurality of blade bodies 141 is connected to the first connecting ring 142, and one end of each blade body 141 is connected to the second connecting ring 143.
[0062] Specifically: a plurality of blade bodies 141 are provided between the first connecting ring 142 and the second connecting ring 143, and the plurality of blade bodies 141 are distributed at intervals along the circumference of the first connecting ring 142 and the second connecting ring 143, and the interval between adjacent blade bodies 141 is equal, so that air can be discharged from the gaps between the blade bodies 141.
[0063] Furthermore, referring to Figure 1 and Figure 2 Each blade assembly 14 is a curved sheet structure, and multiple blade bodies 141 are distributed at intervals.
[0064] Specifically, the cross-section of the blade assembly 14 can be an arc-shaped C-shaped structure or an S-shaped structure, so that a curved interval space is formed between adjacent blade bodies 141, and the air can be discharged more quickly and smoothly during the rotation of the impeller mechanism 1.
