[0037] The following will be combined with Figures 1 to 5 to describe the exhaust device and septic tank system provided by the present utility model.

[0038] Refer to Figures 1 to 3 As shown, the exhaust device 10 provided by the embodiments of the present utility model includes: an exhaust pipe 110 and an auxiliary exhaust assembly 120.

[0039] The auxiliary exhaust assembly 120 includes a first annular flow guide member 121, a second annular flow guide member 122 and a third annular flow guide member 123 that are coaxially arranged vertically and at intervals. A suction cavity 124 is formed at the center of the first annular flow guide member 121, the second annular flow guide member 122 and the third annular flow guide member 123. The suction cavity 124 is communicated with the exhaust end of the exhaust pipe 110.

[0040] A first air intake space is formed between the first annular flow guide member 121 and the second annular flow guide member 122, and a second air intake space is formed between the second annular flow guide member 122 and the third annular flow guide member 123. Both the first air intake space and the second air intake space are communicated with the suction cavity 124.

[0041] Four first partitions 125 are evenly distributed in the circumferential direction between the first annular flow guide member 121 and the second annular flow guide member 122 to divide the first intake space into four first intake chambers 126. Four second partitions 127 are evenly distributed in the circumferential direction between the second annular flow guide member 122 and the third annular flow guide member 123 to divide the second intake space into four second intake chambers 128. The first intake chambers 126 and the second intake chambers 128 are arranged alternately in the circumferential direction.

[0042] The outer diameters of the first annular flow guide member 121 and the second annular flow guide member 122 gradually decrease from bottom to top.

[0043] For the exhaust device 10 provided by the present utility model, by arranging the auxiliary exhaust assembly 120, air can be guided to the suction chamber 124 through the first intake space and the second intake space formed between the first annular flow guide member 121, the second annular flow guide member 122 and the third annular flow guide member 123. Moreover, since the outer diameters of the first annular flow guide member 121 and the second annular flow guide member 122 gradually decrease from bottom to top, an inclined upward flow guiding effect can be provided to the external air flow, so that the air flow entering the suction chamber 124 through the first intake space and the second intake space forms an upward suction effect on the exhaust pipe 110, thereby improving the exhaust efficiency of the exhaust pipe 110. In addition, by arranging the first partitions 125 and the second partitions 127, the first intake space and the second intake space can be divided into the first intake chambers 126 and the second intake chambers 128 facing different directions, which is convenient for the external air flow to enter the suction chamber 124 and improves the exhaust efficiency of the exhaust pipe 110.

[0044] Specifically, in this embodiment, the first annular flow guide member 121, the second annular flow guide member 122 and the third annular flow guide member 123 are all conical cylindrical components, and openings are provided at both the upper and lower ends thereof.

[0045] The four first partitions 125 evenly divide the first intake space into four first intake chambers 126, and the four first intake chambers 126 respectively correspond to four air inlet directions. Similarly, the four second partitions 127 evenly divide the second intake space into four second intake chambers 128, and the four second intake chambers 128 respectively correspond to four air inlet directions. Since the four first intake chambers 126 and the four second intake chambers 128 are arranged alternately, the auxiliary exhaust assembly 120 can adapt to the air inlet from eight directions.

[0046] As an example, the four first intake chambers 126 and the four second intake chambers 128 can be configured to face due east, due south, due west, due north, southeast, northeast, southwest and northwest directions respectively. So that the auxiliary exhaust assembly 120 can introduce the external air flow into the suction chamber 124 under various wind direction conditions, provide an outward suction effect on the exhaust pipe 110, and thus improve the exhaust effect.

[0047] SeeFigures 1 to 3 As shown, according to some embodiments of the present utility model, the auxiliary exhaust assembly 120 further includes a fourth annular flow guide member 129. The fourth annular flow guide member 129 is coaxially and spaced below the first annular flow guide member 121, and the fourth annular flow guide member 129 is connected to the exhaust end of the exhaust pipe 110. A third intake space is formed between the fourth annular flow guide member 129 and the first annular flow guide member 121, and the third intake space is communicated with the suction chamber 124. The outer diameter of the fourth annular flow guide member 129 gradually decreases from bottom to top. By providing the fourth annular flow guide member 129 below the first annular flow guide member 121, the flow guide surface formed by its outer wall can be used to introduce the external air flow into the suction chamber 124 through the third intake space, further improving the exhaust effect of the exhaust pipe 110.

[0048] Specifically, the shape of the fourth annular flow guide member 129 is the same as that of the first annular flow guide member 121, the second annular flow guide member 122, and the third annular flow guide member 123, and it is also a conical tube-shaped component with openings at both its upper and lower ends.

[0049] See Figure 2 and Figure 3 As shown, according to some embodiments of the present utility model, the vertical distance ( Figure 3 L1 in Figure 3 ) between the upper end of the fourth annular flow guide member 129 and the lower end of the first annular flow guide member 121 is less than or equal to 2 mm. The vertical distance ( Figure 3 L2 in ) between the upper end of the first annular flow guide member 121 and the lower end of the second annular flow guide member 122 is less than or equal to 2 mm. The vertical distance (

[0050] L3 in Figure 2 ) between the upper end of the second annular flow guide member 122 and the lower end of the third annular flow guide member 123 is less than or equal to 2 mm. By configuring the vertical distances between the upper end of the fourth annular flow guide member 129 and the lower end of the first annular flow guide member 121, the upper end of the first annular flow guide member 121 and the lower end of the second annular flow guide member 122, and the upper end of the second annular flow guide member 122 and the lower end of the third annular flow guide member 123 to be less than or equal to 2 mm, the air flow entering the first intake space, the second intake space, and the third intake space is difficult to overflow to the outside from the gap between adjacent flow guide members, which can further improve the exhaust effect of the exhaust pipe 110.

[0050] See Figure 2 and Figure 3As shown, according to some embodiments of the present utility model, the inner diameters of the first annular flow guide member 121, the second annular flow guide member 122, and the third annular flow guide member 123 gradually decrease from bottom to top in terms of outer diameter. By configuring the inner diameters of the first annular flow guide member 121, the second annular flow guide member 122, and the third annular flow guide member 123 to gradually decrease from bottom to top in terms of outer diameter, it is possible to make the cross-sectional areas of the first intake cavity 126 and the second intake cavity 128 gradually decrease from bottom to top. When the external air flow enters the first intake cavity 126 and the second intake cavity 128, under the guiding action of the outer wall of the flow guide member, it flows obliquely upward, and the flow velocity gradually increases, which can further enhance the suction effect on the exhaust pipe 110.

[0051] See Figure 4 As shown, according to some embodiments of the present utility model, an air intake structure 111 is provided on the side wall of the exhaust pipe 110. The air intake structure 111 is used to introduce air into the exhaust pipe 110 to prevent condensation and freezing inside the exhaust pipe 110. Since the temperature is relatively low in winter in cold regions, condensation and freezing are likely to occur inside the exhaust pipe 110, affecting the exhaust effect. By providing the air intake structure 111 on the side wall of the exhaust pipe 110, the external air flow can enter the exhaust pipe 110 through the air intake structure 111, preventing condensation and freezing inside the exhaust pipe 110, and enabling the exhaust pipe 110 to maintain a better exhaust effect for a long time.

[0052] According to some embodiments of the present utility model, a plurality of air intake structures 111 are provided on the side wall of the exhaust pipe 110 at intervals along its length direction. When the length of the exhaust pipe 110 is relatively long, by providing a plurality of air intake structures 111 on the side wall of the exhaust pipe 110 at intervals along its length direction, the anti-condensation and freezing effect inside the exhaust pipe 110 can be improved. Correspondingly, each air intake structure 111 is provided with a sliding switch 112.

[0053] Furthermore, according to some embodiments of the present utility model, the exhaust device 10 further includes a sliding switch 112. The sliding switch 112 is slidably engaged with the side wall of the exhaust pipe 110 to open or close the air intake structure 111. By providing the sliding switch 112, when the ambient temperature is relatively high (such as in summer), the air intake structure 111 can be closed through the sliding switch 112 to avoid the air intake structure 111 affecting the suction effect of the auxiliary exhaust assembly 120 on the exhaust pipe 110.

[0054] Specifically, in this embodiment, the sliding switch 112 is a sleeve-type sliding switch, which is sleeved on the outer wall of the exhaust pipe 110, and the air intake structure 111 can be opened or closed by sliding up and down. Since there is a certain frictional force between the inner wall of the sleeve-type sliding switch and the outer wall of the exhaust pipe 110 itself, without the application of external force, the sleeve-type sliding switch can maintain its current height without the need for additional limiting structures.

[0055] In some embodiments, a locking screw or the like can also be used to lock and fix the sleeve-type sliding switch.

[0056] See Figure 4 As shown, according to some embodiments of the present invention, the air intake structure 111 includes a plurality of air intake holes arranged circumferentially on the side wall of the exhaust pipe 110. By configuring the air intake structure 111 as a plurality of air intake holes arranged on the side wall of the exhaust pipe 110, it can ensure that the air flow from all directions outside can smoothly enter the exhaust pipe 110. Moreover, since the air intake holes have a smaller size compared to air intake structures 111 such as grooves or openings, the probability of foreign solid impurities entering the exhaust pipe 110 from the outside can be effectively reduced, ensuring that the air intake structure 111 can be used stably for a long time.

[0057] See Figure 1 As shown, according to some embodiments of the present invention, a rain cap 130 is provided at the outlet end of the third annular deflector 123. By providing the rain cap 130, it can prevent rainwater from entering the septic tank 20 through the exhaust pipe 110.

[0058] The septic tank system provided by the present invention will be described below. The septic tank system described below can be mutually corresponding and referred to the exhaust device 10 described above.

[0059] See Figure 5 As shown, the septic tank system provided by the embodiments of the present invention includes: a septic tank 20 and the exhaust device 10 described in any one of the above embodiments. The septic tank 20 is provided with an exhaust port, and the inlet end of the exhaust pipe 110 is connected to the exhaust port.

[0060] For the septic tank system provided by the present invention, due to the adoption of the above exhaust device 10, it has a better exhaust effect and can effectively prevent the odor from accumulating in the septic tank 20.

[0061] It should be noted that the septic tank 20 has at least one exhaust port, such as a single or multiple exhaust ports. The number of the exhaust devices 10 corresponds to the number of the exhaust ports one by one.

[0062] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
