For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0037] The breathable valve assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, the breathable valve assembly 100 according to the embodiment of the present invention includes a housing 1, a breathable valve body 2 and a dustproof device 3.

[0039] Specifically, the shell 1 defines an inner cavity 12, which can accommodate other components of the breathable valve assembly 100 or other components assembled with the breathable valve assembly 100, thereby preventing external forces from directly impacting the more delicate components in the inner cavity 12, protecting the components in the inner cavity 12, and increasing the strength of the breathable valve assembly 100.

[0040] Further, if Figure 1 As shown, the housing 1 is provided with a mounting hole 11, and the breather valve body 2 is inserted into the mounting hole 11. For example, the breather valve assembly 100 is used in a reducer. When the reducer is operating, the friction of the internal gears and the agitation of the oil generate heat, which in turn causes the internal gas to expand, resulting in an increase in internal pressure. When the internal air pressure exceeds a certain value, the breather valve body 2 automatically opens and discharges excess gas, thereby preventing the reducer from being damaged or malfunctioning due to excessive internal air pressure. By allowing the free inflow and outflow of gas, the breather valve body 2 can help the reducer dissipate some heat, improve heat dissipation efficiency, and help the reducer operate within a reasonable temperature range, thereby improving its operating efficiency and durability.

[0041] Furthermore, the dustproof device 3 is located within the inner cavity 12 and is provided on the breathable valve body 2. The dustproof device 3 is fixedly connected to the housing 1 and is used to prevent particulate matter within the inner cavity 12 from clogging the breathable valve body 2. It is understood that when components within the inner cavity 12 stir the airflow, some particulate matter may be generated. These particulate matter then moves within the inner cavity 12 with the airflow. The dustproof device 3 can prevent these particulate matter from entering the breathable valve body 2, thereby preventing the particulate matter from accumulating in the breathable valve body 2 and clogging the breathable valve body 2, thereby achieving a good dustproof effect.

[0042] According to the breathable valve assembly 100 of the embodiment of the present invention, by inserting the breathable valve body 2 into the mounting hole 11 on the shell 1, the air pressure balance between the inner cavity 12 and the external atmosphere can be ensured, thereby preventing the air pressure in the inner cavity 12 from being too high or too low, and helping the inner cavity 12 to dissipate heat. The dustproof device 3 is located at the breathable valve body 2 in the inner cavity 12. The dustproof device 3 can block particulate matter from entering the breathable valve body 2, thereby preventing particulate matter from being enriched at the breathable valve body 2 and clogging the breathable valve body 2, thereby having a good dustproof effect.

[0043] In addition, the air valve body 2 is detachably connected to the shell 1, the air valve body 2 can be replaced regularly, and the replacement price of the air valve body 2 is low; and the air valve body 2 can be arranged according to installation requirements to match different usage requirements.

[0044] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the dustproof device 3 includes a dustproof shell body 31 and a dustproof side plate 32. The dustproof shell body 31 is covered at the mounting hole 11 and together with the shell 1 defines a dustproof cavity 311. The air valve body 2 is connected to the dustproof cavity 311. Particles entering the dustproof device 3 can be deposited at the bottom of the dustproof cavity 311 to avoid clogging the air valve body 2. The upper end of the dustproof cavity 311 is provided with an air flow inlet 312, which facilitates the air circulation in the dustproof cavity 311. When the air pressure in the inner cavity 12 is high, the air flow in the inner cavity 12 can enter the dustproof cavity 311 through the air flow inlet 312 and exhaust to the external atmosphere through the air breathable valve body 2 in the dustproof cavity 311. At the same time, when the air pressure in the inner cavity 12 is low, the external atmosphere enters the dustproof cavity 311 through the air breathable valve body 2 and enters the inner cavity 12 from the air flow inlet 312, thereby achieving air pressure balance in the inner cavity 12; the dustproof side panel 32 is arranged in the dustproof cavity 311 and is at least partially located above the mounting hole 11. The dustproof side panel 32 can further block particulate matter and reduce the risk of particulate matter clogging the air breathable valve body 2.

[0045] Further, if Figure 3 and Figure 4 As shown, the length direction of the dustproof side plate 32 (as shown Figure 4 One end of the dustproof side plate 32 (in the first direction shown) is connected to the inner wall 314 of the dustproof cavity 311, and the other end is inclined upward and separated from the other side wall 314 arranged oppositely, which can bounce some particles to the outside of the dustproof cavity 311. At the same time, particles can accumulate at the position where the dustproof side plate 32 is connected to the inner wall 314 of the dustproof cavity 311, which can further reduce the risk of particles clogging the air valve body 2.

[0046] Furthermore, if Figure 4 As shown, there are multiple dustproof side plates 32, and the multiple dustproof side plates 32 are arranged in the up and down directions (such as Figure 4 The spacing arrangement in the upper and lower directions shown in the figure can prevent particles from approaching the air valve body 2 many times, avoid the accumulation of particles in the air valve body 2, and the structure of the dustproof device 3 is relatively simple and the cost is low.

[0047] Furthermore, if Figure 3 and Figure 4As shown, along the vertical direction, two adjacent dustproof side panels 32 are respectively connected to the two opposite side walls 314 of the dustproof cavity 311. In the horizontal projection, the two adjacent dustproof side panels 32 have an overlapping area. The multiple dustproof side panels 32 can form a maze-like structure, which can guide the flow direction of the airflow entering the dustproof cavity 311. The dustproof device 3 is dust-proof and oil-proof by utilizing centrifugal force, and it intercepts larger and heavier dust particles to prevent them from clogging the breathable valve body 2 and preventing particulate matter from accumulating in the breathable valve body 2. The dustproof device 3 has a relatively simple structure and low cost. An airflow inlet 312 is formed between the two uppermost dustproof side panels 32, allowing the airflow entering the dustproof cavity 311 to smoothly enter the maze-like structure and ensure the dustproof effect of the dustproof side panels 32.

[0048] In addition, the labyrinth-like structure formed by the multiple dust-proof side plates 32 has a certain oil-gas coarse separation effect, which can effectively avoid the problem of rapid reduction in air permeability caused by oil leakage in the inner cavity 12.

[0049] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the dustproof shell body 31 includes a bottom wall 313 and a side wall 314, and the width direction of the dustproof side plate 32 (such as Figure 3 One end of the dustproof side panel 32 (in the second direction shown) is connected to the bottom wall 313, and the other end is against the housing 1, making the position of the dustproof side panel 32 relatively simple and reliable; one end of the side panel 314 in the width direction is connected to the bottom wall 313 and the other end is against the housing 1, and one end of the dustproof side panel 32 in the length direction is connected to the side wall 314. At this time, the dustproof cavity 311 formed by the dustproof housing body 31 and the housing 1 is relatively closed, which can prevent airflow from crossing in the inner cavity 12 and prevent the dustproof device 3 from failing. It can also contain particulate matter in the dustproof cavity 311 to prevent it from affecting the ventilation effect of the breathable valve body 2.

[0050] In some embodiments of the present invention, a flywheel is provided in the inner cavity 12, and the opening direction of the air flow inlet 312 is set downstream of the highest point of the flywheel along the rotation direction of the flywheel, which can reduce the risk of rust and other particles or dust on the flywheel entering the dustproof cavity 311 when the flywheel rotates, avoid the accumulation of particles in the air valve body 2, and further reduce the risk of particles clogging the air valve body 2, thereby avoiding affecting the ventilation effect of the air valve body 2.

[0051] In some embodiments of the present invention, the dustproof device 3 is an integrated part, which can reduce the manufacturing cost of the dustproof device 3 and the structure of the dustproof device 3 is relatively simple.

[0052] In some embodiments of the present invention, the dustproof device 3 is a plastic part, which is light in weight. When the air valve assembly 100 is used in a vehicle, the vehicle can be lightweight. In addition, the injection molding process is relatively mature and the manufacturing process is relatively simple.

[0053] In some embodiments of the present invention, Figure 1 As shown, the air valve assembly 100 also includes a first sealing ring 4, which is arranged between the inner peripheral wall of the mounting hole 11 and the outer peripheral wall of the air valve body 2, and can ensure the sealing effect of the air valve body 2 and the shell 1, and avoid air leakage between the air valve body 2 and the shell 1.

[0054] The present invention also provides a reducer having the breathable valve assembly 100 of the above embodiment.

[0055] The reducer according to the embodiment of the present invention includes the above-mentioned breathable valve assembly 100 .

[0056] Specifically, when the reducer is operating, friction between the internal gears and the agitation of the oil generate heat, which in turn causes the internal gas to expand and increase internal pressure. When the internal pressure exceeds a certain value, the vent valve body 2 automatically opens to expel excess gas, thus preventing damage or malfunction of the reducer caused by excessive internal pressure. By allowing the free flow of gas, the vent valve body 2 helps the reducer dissipate some heat, improves heat dissipation efficiency, and helps the reducer operate within a reasonable temperature range, thereby enhancing its operating efficiency and durability.

[0057] According to the reducer of the embodiment of the present invention, by providing the above-mentioned breathable valve assembly 100, by passing the breathable valve body 2 through the mounting hole 11 on the shell 1, it can ensure the air pressure balance between the inner cavity 12 and the external atmosphere, avoid the air pressure in the inner cavity 12 being too high or too low, and help the inner cavity 12 to dissipate heat, and the dustproof device 3 is located at the breathable valve body 2 in the inner cavity 12.
