Preferably, in the present application, the rotation axis of the valve 30 coincides with the central symmetry line of the valve 30, and the rotation axis of the valve 30 coincides with the central symmetry line of the cross section of the fresh air inlet 21 passing through the rotation axis of the valve 30.
For example, in the present application, as shown in fig. 1, the cross section of the fresh air inlet 21 is circular, and the rotation axis of the valve 30 passes through the central point of the cross section of the fresh air inlet 21 and extends along the radial direction of the cross section of the fresh air inlet 21. Correspondingly, the valve 30 is a circular plate-shaped structure, and the fresh air inlet 21 is opened or closed by the rotation of the valve 30.
As shown in fig. 1 and 2, a pipe joint 10 according to an embodiment of the present invention includes: a first pipe section 11 and a second pipe section 12.
Specifically, one end of the first pipe segment 11 is suitable for being connected with the fresh air inlet 21, one end of the second pipe segment 12 is connected with the other end of the first pipe segment 11, the aperture of the second pipe segment 12 is smaller than that of the first pipe segment 11, and the axis of the second pipe segment 12 is parallel to the axes of the fresh air inlet 21 and the first pipe segment 11, is perpendicular to the rotation axis of the valve 30 and is positioned on one side of the rotation axis of the valve 30.

The aperture of the second pipe section 12 is smaller than that of the first pipe section 11, and the outer diameter of the corresponding second pipe section 12 is smaller than that of the first pipe section 11, mainly to adapt to the connection of different fresh air pipes. The pipe diameter at the new trend pipe is the same roughly with the aperture of new trend import 21, when can fitting, along coupling 10's length direction, coupling 10's aperture can be the same, when the pipe diameter of new trend pipe is less than the aperture of new trend import 21, can't realize connecting coupling 10 through the same pipe diameter, therefore, set up coupling 10 of this application and make the pipe diameter of first pipeline section 11 be greater than the pipe diameter of second pipeline section 12, when the pipe diameter of new trend pipe is less can't be connected with the pipe diameter is the same roughly with the pipe diameter of new trend import 21's aperture coupling 10 cooperation, can be connected new trend pipe and second pipeline section 12 cooperation, satisfy user's user demand, thereby avoid the user to enlarge the wall hole.
In addition, the axis of the second pipe section 12 is parallel to the axes of the fresh air inlet 21 and the first pipe section 11, so that the pipe joint 10 extends along a straight line as a whole, and the resistance to the flow of air flow and the noise can be reduced. Further, the axis of the second pipe section 12 is perpendicular to the axis of rotation of the valve 30 and is located on one side of the axis of rotation of the valve 30. When the valve 30 is rotated to a position parallel to the central axis of the second pipe section 12 (as shown by the dashed line of the valve 30 in fig. 1 and fig. 2), that is, when the valve 30 opens the fresh air inlet 21, because the rotation axis of the second pipe section 12 is located at one side of the rotation axis of the valve 30, the valve 30 is spaced apart from the center of the second pipe section 12, and the area of the valve 30 covering the second pipe section 12 is smaller than the area of the valve 30 located on the central axis of the second pipe section 12, which is beneficial to increasing the intake air amount of the fresh air inlet 21 and reducing noise.
According to the pipe joint 10 of the embodiment of the utility model, the axis of the second pipe section 12 is parallel to the axes of the fresh air inlet 21 and the first pipe section 11, and the axis of the second pipe section 12 is perpendicular to the rotation axis of the valve 30 and is positioned at one side of the rotation axis of the valve 30, so that the air flow can flow linearly as a whole, the flow resistance of the air flow is reduced, the noise is reduced, and when the valve 30 is at the position of opening the fresh air inlet 21, namely when the valve 30 is parallel to the axes of the second pipe section 12 and the first pipe section 11, the shielding area of the valve 30 on the second pipe section 12 can be reduced, the air intake of the fresh air inlet 21 is favorably increased, and the noise can be further reduced.
In some embodiments of the present invention, as shown in fig. 1 and 2, the axis of the first tube segment 11 coincides with the axis of the fresh air inlet 21. From this be convenient for first pipeline section 11 and new trend between 21 be connected, and can reduce the turning between first pipeline section 11 to new trend import 21, the flow of the air current of being convenient for reduces the resistance that the air current flows, noise abatement. In this case, the second tube section 12 is eccentrically disposed with respect to the first tube section 11 and with respect to the fresh air inlet 21, since the axis of the second tube section 12 is parallel to and spaced apart from the axis of the first tube section 11.
Further, as shown in fig. 1 and 2, the plane defined by the axis of the first pipe segment 11 and the axis of the second pipe segment 12 is perpendicular to the rotational axis of the valve 30. It can be understood that the second pipe section 12 is located at the position where the distance between the rotation axis of the valve 30 and the inner wall of the fresh air inlet 21 is the largest, so that the second pipe section 12 is convenient to arrange, the airflow can flow conveniently, the airflow is ensured to flow linearly in the process of entering the first pipe section 11 from the second pipe section 12 and then entering the fresh air inlet 21, the airflow flowing resistance is reduced, and the noise generated in the airflow flowing process is reduced.
In some embodiments of the present disclosure, a limiting structure 13 is disposed on at least one of the first pipe segment 11 and the second pipe segment 12, and the valve 30 has a wind guiding position (shown in fig. 1 and 2 as a solid line position of the valve 30) abutting against the limiting structure 13, in which the valve 30 is inclined toward a direction close to an axis of the second pipe segment 12 in a direction from the first pipe segment 11 to the second pipe segment 12. Wherein, in the wind-guiding position, the angle between the plane of valve 30 and the perpendicular to new trend air inlet axis is alpha, and alpha satisfies: alpha is less than 90 degrees. Therefore, the air flow resistance can be further reduced, and the air duct performance is improved.
In addition, when the user selects the fresh air pipes with different installation pipe diameters, no matter what pipe joint 10 is selected, only the same set of electric control parameter control is needed, the electric control parameter does not need to be changed, the fresh air valve 30 can automatically stop at the angle most beneficial to air inlet when being opened only by being limited by the limiting structure 13, and the optimal air inlet angle is automatically adjusted, so that the air duct performance is improved.
Specifically, referring to fig. 1 and 2, when the user selects a fresh air duct having an aperture substantially the same as that of the fresh air inlet 21, since the aperture of the pipe joint 10 is also substantially the same as that of the fresh air inlet, when the fresh air is opened, the inner wall of the pipe joint 10 is concentric with the fresh air inlet 21, and since there is no structural interference, the valve 30 is given to rotate the electrical control parameter 90 ° clockwise, so that the valve 30 can rotate 90 ° clockwise from the initial position (the position where the fresh air inlet 21 is closed) without a barrier. When the user chooses the fresh air pipe of less pipe diameter for use, can adopt the coupling 10 of this application, fresh air pipe and second pipeline section 12 are connected, give valve 30 equally and rotate automatically controlled parameter 90, but this moment because limit structure 13's restriction for valve 30 actually can only rotate and be less than 90, and valve 30 also is in the best air inlet position this moment.
As shown in fig. 2, in the air duct system, the position where the gap between the two side walls is the smallest is called the throat, where the flow resistance is the largest, the size of the throat affects the performance of the whole air duct, and the larger the size of the throat is, the smaller the resistance of the whole air duct is, and the better the performance of the air duct is. In the present application, if the valve 30 rotates 90 °, the sizes of the throats (positions shown by the dashed square circles) at the two sides are D1 and D2, respectively, and when the valve 30 rotates only to abut against the limit structure 13, the sizes of the throats at the two sides are D3 and D4, respectively, wherein D3 is larger than D1, and D4 is larger than D2, as a whole, the size of the throat is enlarged when the valve 30 rotates to abut against the limit structure 13, and the improvement on the performance of the air duct is considerable.
In some embodiments of the present invention, as shown in fig. 1 and 2, at least one of the second pipe segment 12 and the first pipe segment 11 is provided with an avoidance groove of the avoidance valve 30, and a side wall of the avoidance groove is formed as the limit structure 13. Because the valve 30 rotates to the position of opening new trend import 21 by the position of closing new trend import 21, certain space is required in the rotation of valve 30, and a part of valve 30 can rotate towards new trend import 21 outside, and first pipeline section 11 and second pipeline section 12 can block the rotation of valve 30, through set up on at least one in first pipeline section 11 and second pipeline section 12 and dodge the groove for valve 30 can be smooth rotates through dodging the groove. Wherein the side wall of the avoiding groove is formed into a limiting structure 13, when the valve 30 rotates to the side wall stopping with the avoiding eraser, the valve 30 can not continue to rotate due to the blocking effect of the side wall of the avoiding groove, so that the valve 30 is kept at the position, and at the moment, part of the structure of the valve 30 is positioned in the avoiding groove.

A fresh air module according to an embodiment of the present invention is described below.
As shown in fig. 1 and 2, the fresh air module according to the embodiment of the present invention includes a housing 20, a valve 30, and a pipe joint 10.
Specifically, the housing 20 is provided with a fresh air inlet 21, and the valve 30 is rotatably disposed in the fresh air inlet 21 to open or close the fresh air inlet 21. Specifically, the cross section of the fresh air inlet 21 is circular, the valve 30 is of a circular plate-shaped structure, and the rotation axis of the valve 30 extends along the radial direction of the fresh air inlet 21, namely the rotation axis of the valve 30 is intersected with the central axis of the fresh air inlet 21.
As shown in fig. 1 and 2, the pipe joint 10 comprises a first pipe segment 11 and a second pipe segment 12, wherein one end of the first pipe segment 11 is connected and communicated with a fresh air inlet 21, one end of the second pipe segment 12 is connected with one end of the first pipe segment 11 far away from the fresh air inlet 21, and one end of the second pipe segment 12 far away from the first pipe segment 11 is suitable for being connected with a fresh air pipe. The idle running of the first pipe section 11 can be substantially 53mm, and the aperture of the second pipe section 12 can be 30mm, and the following description will be given by taking the fresh air pipe as the fresh air pipe with the diameter of 30mm, wherein the fresh air pipe is divided into the fresh air pipe with the diameter of 53 mm.
The cross sections of the first pipe section 11 and the second pipe section 12 are both circular, and the aperture of the first pipe section 11 is substantially the same as that of the fresh air inlet 21, so that the connection between the first pipe section 11 and the fresh air inlet 21 is convenient to realize. In addition, the central axis of the first pipe section 11 coincides with the central axis of the fresh air inlet 21.

In fact, compared with the solution of the second pipe segment 12 concentric with the first pipe segment 11, the unobstructed intake air area of the second pipe segment 12 is about 4%, and the air volume of the fresh air inlet 21 can be increased by about 4%.
In addition, be equipped with on first pipeline section 11 and the second pipeline section 12 and dodge the groove in order to guarantee the smooth rotation of valve 30, in addition, the lateral wall that dodges the groove forms into the limit structure 13 that ends with valve 30, when valve 30 ends with the lateral wall that dodges the groove first pipeline section 11 extremely in the direction of second pipeline section 12, valve 30 orientation is close to the direction slope of second pipeline section 12 axis can promote the wind channel performance to it is spacing through limit structure 13, need not to change automatically controlled parameter, just realize valve 30 self-adaptation to the best air inlet position under the eccentric state, further promote the wind channel performance, following explanation utility model discloses the principle.
When the user chooses the fresh air pipe that the pipe diameter is 53mm for use, can adopt the coupling 10 that the aperture is 53mm, because this coupling 10 aperture is the same with fresh air intake maximum diameter, consequently need not do unnecessary structural design, when fresh air opened, coupling 10 inner wall and fresh air inlet 21 are concentric. Due to the absence of structural interference, the given valve 30 rotates the electrical control parameter by 90 ° so that the valve 30 can rotate 90 ° clockwise from the initial position without obstruction.
When a user selects a fresh air pipe with the pipe diameter of 30mm, the pipe joint 10 is adopted, the second pipe section 12 is eccentrically arranged relative to the first pipe section 11, the rotating electric control parameter of the valve 30 is also given to be 90 degrees, at the moment, due to the limitation of the limiting structure 13, the valve 30 can only rotate 80 degrees actually and is stopped against the limiting structure 13, and at the moment, the valve 30 is also at the optimal air inlet position. The specific principle is as shown in fig. 2, in the air duct system, the position where the gap between the two side wall surfaces is the smallest is called the throat portion, where the flow resistance is the largest, the size of the throat portion affects the performance of the whole air duct, and the larger the size of the throat portion is, the smaller the resistance of the whole air duct is, and the better the performance of the air duct is. On the premise of the eccentricity of the air duct, if the valve 30 rotates 90 °, the sizes of the throats on both sides are D1-5.3 mm and D2-25.3 mm, respectively, and when the air duct rotates only 80 °, the sizes of the throats on both sides are D3-8.1 mm and D4-28.5 mm, respectively, in a whole view, the size of the throat is enlarged by about 15% when the air duct rotates 80 °, and the improvement of the performance of the air duct is considerable.
When a user selects a use scene without expanding a wall hole, a fresh air pipe with the diameter smaller than that of the fresh air inlet needs to be installed, and the pipe joint 10 structure adopted by the utility model has better air duct performance and lower noise with the same air volume. And through the spacing design of structural, the wind channel of eccentric air inlet of cooperation for no matter the user with the fresh air pipe of which kind of pipe diameter, only with one set of automatically controlled parameter alright with the automatically regulated that can realize the 30 angles of new valve, thereby improve the fresh air efficiency of taking a breath of whole module. The data of the D30 air duct test is shown in Table 1, the same set of electric control parameters are used for controlling the opening of the valve 30 to be 90 degrees, and the self-adjusting valve 30 has the optimal structural performance. At this time, the opening degree of the valve 30 is controlled to be 90 °, so the air volume of the D53 pipe is not affected.
TABLE 1 fresh air Module test results
In summary, no matter the user chooses to ream the fresh air pipe (D53) or not (D30), the same set of electrical control parameters can be used to control the rotation angle of the valve 30, but different actual rotation angles of the valve 30 can be obtained. Under the condition of no hole expansion, the circle centers of the second pipe section 12 and the fresh air inlet 21 are different, and the position of the fresh air valve 30 is different from the hole expansion condition, so that the maximum hole expansion-free air volume is obtained.
