For instance, various combinations of specific technical f eatures / embodiments can be crafted, reflecting distinct implementations in shoe sole design. To avoid unnecessary repetition, the myriad potential combinations of certain technical f eatures / embodiments within this invention will not be further elucidated.

[0030] Please note that the terms "arrangement" and "connection" should be understood in a broad sense, for example, they can be fitted, installed, and connected directly, or they can be arranged and connected indirectly through centralized components and structures. Additionally, the direction or positional relationship is indicated by "center, " "top, " "bottom," "left," "right," "vertical," "horizontal," "inner," "outer," and others in this invention.

[0031] As shown in Figure 1, this embodiment of the invention provides a water and air respirator mounted on shoes, including upper shell (1) and lower shell (2) . The upper shell (1) is made of soft material such as silicone, and the lower shell (2) is made of hard material such as rigid plastic. Upper shell (1) and lower shell (2) are connected to form a closed cavity within. During use, the upper shell (1) undergoes deformation relative to the lower shell (2) , causing the volume inside the closed cavity to change, forming a structure similar to air pockets.

[0032] At the same time, the lower shell (2) is equipped with an inlet (3) and an outlet (4) . The inlet (3) is equipped with the first one-way valve (5) , and the outlet (4) is equipped with the second one-way valve (6) . One-way valve (5) , the first is used for the one-way entry into the entry channel (3) .

[0033] The second one-way valve (6) is used for one-way discharge from the exit channel (4) . Therefore, when the upper shell (1) is pressed and reshaped to reduce the sealed cavity volume. The air and / or fluid within the cavity can be removed from the insole through the exit (4) . When the upper shell (1) returns to its initial position and the cavity volume is closed, the sealed cavity expands, the sealed cavity can pass through the inlet 3 to suck in air and / or liquid moisture inside the shoe, thereby making the inside of the shoe, especially the sole (10) to be breathable and dry.

[0034] Between the upper shell (1) and the lower shell (2) there is an elastic body. In this embodiment, the elastic body is a compression spring (7) . The upper end of the compression spring (7) is in contact with the upper shell (1) , and the lower end of the compression spring (7) is in contact with the lower shell (2) . Therefore, when the foot of the user steps on the upper shell (1) , and the upper shell (1) , then presses the elastic body (7) during the pressing process. This will cause the volume of the sealed or enclosed cavity between the upper shell (1) and the lower shell (2) decreasing. When the foot is lifted, the upper shell (1) can compress the compression spring (7) . The compression spring (7) will return to its original position after the recovery action, which results in increase the volume of the sealed cavity. Therefore, when the user is walking or running, the volume of the sealed cavity is constantly changing, thus realizing a cyclical process of pumping, and exhausting the shoe, so that the shoe can continue to be in a breathable and dry state.

[0035] It is understood that the respirator is usually installed in the heel part of the sole (10) . When the foot descends, the upper shell (1) is likely to deform excessively, causing the upper surface of the upper shell (1) to collapse relatively to the plane of the heels of the sole (10) . Therefore, the user will feel like leaning, which will affect the user experience. Based on this, in this embodiment, it is optimized that when the pressure spring (7) is in a maximum compression state, the upper shell (1) is flush with the upper surface of the sole (10) so that the user does not feel unstable and want to lean back .

[0036] As a further improvement, in this embodiment, the upper shell (1) is provided with a first connecting column (8) , and the top of the compression spring (7) is wrapped on the first connecting post (8) . At the same time, the lower shell (2) is provided with a second connecting column (9) , and the bottom of the compression spring (7) is sleeved on the second connecting column (9) . Through this arrangement of the first and second connecting column (8 and 9) , on the one hand, make an easy way in installing the pressure spring (7) . Both ends of the pressure spring (7) can be directly sleeved on the connecting columns, which can ensure the position of the pressure spring (7) during use.

[0037] For stability, it is important to set the length of both connecting column (8 and 9) so that the first connecting column (8) and the second connecting column (9) is in contact. The upper shell (1) is in line with the upper surface of the sole (10) , therefor the upper shell (1) cannot be pressed furthermore. At that time, the pressure spring (7) is obviously in the maximum state of compression. Through this arrangement of the first and second connecting column (8 and 9) , the upper shell (1) and the upper surface of the sole (10) can be more stably aligned in a flat position, and the compression spring (7) will not be over compressed due to load weight of the user. Then, the service life of the pressure spring (7) can also be lengthened.

[0038] As a preferred implementation, in this embodiment, the first one-way valve (5) and the second one-way valve (6) are both silicone one-way valves. The structure of the silicone one- way valve can be used to achieve absolute one-way. The operation is by utilizing the resistance of silicone. Ensure the accuracy of the air and / or liquid flow direction inside the shoe to avoid back suction. In this embodiment, periphery of the upper shell (1) and periphery of the lower shell 2 are tightly connected and fixed by a high-frequency welding to form a sealed cavity to ensure the sealing.

[0039] At the same time, as shown in Figure 2, with the same innovative concept, this embodiment is also provided the breathable shoes with the sole (10) . This sole (10) is provided with a plurality of through holes (11) which are connected to the inside of the breathable shoe. The heel of the sole (10) is provided with a mounting groove (12) . This mounting groove (12) is used to attach said respirator. In addition, the sole (10) is provided with a first channel (13) and a second channel (14) . The first channel (13) is connected to the through-hole (11) , and at the same time, the first channel (13) is connected to the inlet (3) of the respirator.

[0040] The second channel (14) is connected to the exit channel of the respirator. The holes (4) are connected, and the second channel (14) is connected to the outside of the sole (10) . Therefore, during the process of emptying the shoes using the respirator, air and / or liquid in the shoe enters the first channel (13) from each hole (11) , then enters the respirator from the inlet (3) , and finally is discharged from the outlet (4) and the second channel (14) to the outside of the shoe.

[0041] It should be noted that the first channel (13) and the second channel (14) may be pipes separately attached to the sole (10) or may be channels opened by the sole (10) itself. The entry channel, the exit channel, inlet, outlet can be more than one in number, respectively.

[0042] The breathable shoes provided in this embodiment has the same beneficial effect as the respirator mentioned above, which will no longer be described herein. The above embodiment is the preferred embodiment of the invention. It should be pointed out that for those who have ordinary skills in the art, some improvements and modifications can be made without departing from the principles described in the present invention, should also be considered as the scope of protection of the present invention.
