[0006] In a first aspect, an embodiment of the present application provides a damper, comprising:

[0007] The valve body has a ventilation area, wherein the ventilation area is provided with a plurality of first ventilation openings;

[0008] The baffle is used to adjust the opening of the first vent, and a plurality of second vents are provided on the baffle, and the second vents are arranged corresponding to the first vents.

[0015] In some embodiments, the valve body is provided with a boss along the circumference of the ventilation area, and slide grooves are provided on opposite sides of the boss, and opposite ends of the baffle are respectively slidably disposed in the two slide grooves.

[0030] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0034] The present application provides an air conditioning device.

[0035] In the embodiment of the present application, the air conditioning device includes a shell and an air valve 100. The shell is provided with a plurality of vents including an air inlet and an air outlet. The air valve 100 is used to adjust the air volume of the vents.

[0036] In the prior art, when the size of the vent is large, a large-stroke wind valve 100 structure is usually used to adjust the air volume of the vent. This has high requirements on the space on both sides of the vent, and usually requires a width equal to the length of the vent to be reserved. However, some air conditioning devices may not provide enough stroke / space on both sides of the vent to push the wind valve 100 to adjust the air volume.

[0037] In order to solve the above technical problems, the present application proposes a damper 100 .

[0038] For ease of description, the length direction of the air valve 100 is defined as the X-axis direction, the width direction of the air valve 100 is defined as the Y-axis direction, and the thickness direction of the air valve 100 is defined as the Z-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0039] The directional terms such as “upper”, “lower”, “top”, “bottom”, “left”, “right”, “inside” and “outside” used in describing the air valve 100 in the embodiment of the present application are mainly based on the position of the air valve 100 in the attached Figure 1The display orientation is explained in detail, with the positive direction of the Z axis being the "top" and "upper", the negative direction of the Z axis being the "bottom" and "lower", the positive direction of the X axis being the "right", the negative direction of the X axis being the "left", the positive direction of the Y axis being the "outside", and the negative direction of the Y axis being the "inside", which does not constitute a limitation on the orientation of the air valve 100 in actual application scenarios.

[0040] See also Figure 1-Figure 5 In the implementation of the present application, the air valve 100 includes a valve body 110 and a baffle 120, the valve body 110 has a ventilation area 111, and the ventilation area 111 is provided with a plurality of first ventilation openings 1111; the baffle 120 is used to adjust the opening of the first ventilation openings 1111, and the baffle 120 is provided with a plurality of second ventilation openings 122, and the second ventilation openings 122 are arranged corresponding to the first ventilation openings 1111, and the baffle 120 is slidably connected to the valve body 110 so that the degree of misalignment between the first ventilation holes and the second ventilation openings 122 can be adjusted.

[0041] It can be understood that the air valve 100 is arranged at the ventilation opening of the shell, the ventilation area 111 of the air valve 100 is arranged corresponding to the ventilation opening of the shell, and the valve body 110 and the shell can be integrally formed or separately formed.

[0042] The technical solution of the present application shortens the adjustment stroke of the air valve 100 by providing a plurality of small-sized first ventilation openings 1111 in the ventilation area 111 of the valve body 110 and providing a plurality of corresponding small-sized second ventilation openings 122 on the baffle 120. During the air volume adjustment process, the sliding of the baffle 120 can change the degree of misalignment between the multiple first vents 1111 and the multiple second vents 122 correspondingly arranged, that is, it can change the degree to which the multiple first vents 1111 are blocked; by sliding the baffle 120 to make the second vents 122 completely staggered with the first vents 1111, the air valve 100 can be closed, that is, the air volume of the first vent 1111 is adjusted to the minimum; by sliding the baffle 120 to move the second vent 122 to a position directly opposite to the first vent 1111, the air valve 100 can be fully opened, that is, the air volume of the first vent 1111 is adjusted to the maximum, and the air volume of the first vent 1111 is switched from the minimum air volume to the maximum air volume by moving the length of the first vent 1111 (the length along the sliding direction of the baffle 120). The air valve 100 provided by the technical solution of the present application can be applicable to various types of large-sized air outlets. The present application divides the existing large-sized air outlet into multiple small-sized air outlets (first air outlets 1111), and divides the baffle 120 into multiple small-sized blocks 121 (located between two adjacent second air outlets 122) corresponding to the small-sized air outlet. This makes it possible to adjust the air volume of the large-sized air outlet by moving the baffle 120 by a smaller stroke, which means that the baffle 120 occupies less space on both sides of the air outlet.

[0043] In the embodiment of the present application, the number of the first vents 1111 and the second vents 122 can be the same or different. Preferably, the number of the first vents 1111 and the second vents 122 is the same. This arrangement allows the first vents 1111 and the second vents 122 to be arranged one-to-one, and by adjusting the misalignment degree between the first vents 1111 and the corresponding second vents 122, the opening of each first vent 1111 can be adjusted.

[0044] In the embodiment of the present application, the shapes of the first vent 1111 and the second vent 122 can independently be rectangular, circular, elliptical or other shapes.

[0045] See also Figure 1 , Figure 2 and Figure 5 In a preferred embodiment, the first vent 1111 and the second vent 122 are both rectangular in shape. This arrangement is more conducive to increasing the opening rate of the ventilation area 111 of the valve body 110 and is more convenient for increasing the opening adjustment range of the first vent 1111.

[0046] In the embodiment of the present application, the shapes of the plurality of first vents 1111 can be the same or different from each other. Correspondingly, the shapes of the plurality of second vents 122 can be the same or different from each other.

[0047] In order to facilitate the proportional adjustment of the opening of each first vent 1111, in a preferred embodiment, regardless of whether the shapes of the multiple first vents 1111 / second vents 122 are the same, the extension length of each first vent 1111 along the X-axis direction is consistent, and correspondingly, the extension length of each second vent 122 along the X-axis direction is consistent.

[0048] In the embodiment of the present application, the opening adjustment range of the first vents 1111 may be 0% to 100%, or 5% to 100%, 10% to 100%, 10% to 99%, etc. The opening adjustment ranges of the first vents 1111 may be the same or different.

[0049] In a preferred embodiment, the opening adjustment range of the first vent 1111 is 0% to 100%, that is, the baffle 120 can adjust the opening of the first vent 1111 to 0%, 20%, 40%, 60%, 80%, 100% or any range therebetween; the first vent 1111 and the second vent 122 are arranged one by one, and the opening adjustment range of each first vent 1111 is 0% to 100%. The baffle 120 has a first position and a second position, and the baffle 120 can slide between the first position and the second position. In the first position, the projections of the first vent 1111 and the second vent 122 on the axial direction (Z-axis direction) of the baffle 120 overlap, and the air valve 100 is fully opened. In the second position, the projections of the first vent 1111 and the second vent 122 on the axial direction (Z-axis direction) of the baffle 120 are staggered, and the air valve 100 is fully closed.

[0050] In the embodiment of the present application, the sizes of the first vent 1111 and the corresponding second vent 122 may be the same or different. Preferably, the size of the second vent 122 is greater than or equal to the first vent 1111.

[0051] Specifically, when the first vent 1111 and the second vent 122 corresponding thereto have the same shape, preferably, the first vent 1111 and the second vent 122 corresponding thereto have the same size; when the first vent 1111 and the second vent 122 corresponding thereto have different shapes, preferably, the size of the second vent 122 is larger than the size of the first vent 1111 corresponding thereto, for example: the first vent 1111 is circular in shape, and the second vent 122 corresponding thereto has a rectangular shape, then the area of ​​the inscribed circle of the second vent 122 is consistent with the area of ​​the first vent 1111. This arrangement enables the opening adjustment range of the first vent 1111 to be between 0% and 100%.

[0052] In the embodiment of the present application, the sizes of the plurality of first vents 1111 may be the same or different. In order to facilitate the adjustment of the openings of the first vents 1111 in the same proportion, the extension lengths of the first vents 1111 arranged in the same row along the Y-axis direction in the X-axis direction are consistent, and the extension lengths of the first vents 1111 arranged in the same column along the X-axis direction in the X-axis direction may be the same or different.

[0053] In the embodiment of the present application, there are various arrangements of the first vents 1111 and the second vents 122 .

[0054] In one embodiment, the plurality of first vents 1111 are sequentially arranged along a first direction, the first direction being the sliding direction of the baffle 120 relative to the valve body 110 during air volume adjustment, that is, the X-axis direction. In this embodiment, the length direction of the first vents 1111 is the second direction, the second direction is perpendicular to the first direction, and the second direction is the Y-axis direction. Specifically, the first vents 1111 extend from the front end to the rear end of the ventilation area 111 in the width direction.

[0055] In the above embodiment, the arrangement of the plurality of second vents 122 is consistent with the arrangement of the plurality of first vents 1111, that is, the plurality of second vents 122 are sequentially arranged along the first direction, and the spacing between two adjacent second vents 122 is consistent with the spacing between two adjacent first vents 1111. In other words, the baffle plate 120 is formed with a plurality of stoppers 121 sequentially arranged at intervals along the first direction, and the stoppers 121 on the baffle plate 120 and the second vents 122 are staggeredly arranged along the first direction.

[0056] In the above embodiment, when the opening area of ​​the ventilation area 111 of the valve body 110 is constant, the smaller the size of the first ventilation opening 1111 and the smaller the distance between two adjacent first ventilation openings 1111, the more conducive it is to reduce the maximum travel distance of the air valve 100. It should be noted that the smaller the size of the first ventilation opening 1111, the greater the total resistance encountered by the gas flowing through the ventilation area 111, so the size of the first ventilation opening 1111 needs to be reasonably designed and should not be too small. Those skilled in the art can make reasonable adjustments according to the actual application scenario, and this application does not specifically limit this.

[0057] See also Figure 5 In another embodiment, a plurality of the first vents 1111 are arranged in a staggered array.

[0058] See also Figure 3 In the above embodiment, the arrangement of the plurality of second vents 122 is consistent with the arrangement of the plurality of first vents 1111, that is, the plurality of second vents 122 are arranged in a staggered array. In other words, the baffle plate 120 is formed with a plurality of stoppers 121 arranged in a staggered array, and the stoppers 121 on the baffle plate 120 are arranged in a staggered array with the second vents 122.

[0059] In the above embodiment, along the second direction, the width of the first vent 1111 / the second vent 122 is L1, and the distance between two adjacent first vents 1111 / the second vent 122 arranged in a row is L2, and L2 ≥ L1. Preferably, L2 = L1, and such a setting is more conducive to improving the opening rate of the ventilation area 111 of the valve body 110. Of course, those skilled in the art can also adjust the relationship between L2 and L1 according to the actual opening rate requirements, and this application does not specifically limit this.

[0060] In the above embodiment, along the first direction, the width of the first vent 1111 / the second vent 122 is d1, and the distance between two adjacent first vents 1111 / the second vent 122 arranged in a row is d2, preferably, d1 = d2. This arrangement allows the opening adjustment range of each first vent 1111 to be between 0% and 100%.

[0061] In the embodiment of the present application, the baffle 120 can be arranged outside or inside the ventilation area 111 of the valve body 110. Preferably, the baffle 120 is arranged inside the ventilation area 111, which is conducive to improving the aesthetics of the air valve 100.

[0062] In the embodiment of the present application, the valve body 110 is provided with a slide groove, and the baffle 120 can be slidably disposed in the slide groove.

[0063] See also Figure 5In one embodiment, the valve body 110 is provided with a boss 112 along the circumference of the ventilation area 111, and slide grooves are provided on opposite sides of the boss 112, and opposite ends of the baffle 120 are respectively slidably disposed in the two slide grooves.

[0064] Specifically, the ventilation area 111 is rectangular, the boss 112 is rectangular ring-shaped, the front and rear ends of the boss 112 are provided with sliding grooves, and the front and rear ends of the baffle 120 can be slidably disposed in the sliding grooves of the front and rear ends of the boss 112 respectively.

[0065] See also Figure 2 and Figure 4 In the above embodiment, along the first direction, the length of the baffle 120 is less than the length of the ventilation area 111, and the length difference between the baffle 120 and the ventilation area 111 is ≥ the extension length of the first ventilation opening 1111 along the first direction. This arrangement allows the left and right ends of the ventilation area 111 of the valve body 110 to reserve sufficient moving space for the baffle 120, which is more conducive to improving the installation convenience and aesthetics of the air valve 100.

[0066] In the above embodiment, the gap width between the baffle 120 and the ventilation area 111 is d3. When the baffle 120 is made of self-lubricating material, d3=0mm; when the baffle 120 is made of other non-self-lubricating materials, the front and rear ends of the baffle 120 are connected to the valve body 110 through pulleys, and 0mm<d3≤1mm. This setting can take into account the sliding convenience of the baffle 120 and the opening control range of the first vent 1111.

[0067] See also Figure 5 On the basis of the above embodiment, in one embodiment, the end of the boss 112 in the first direction is provided with an opening 1121 connected with the slide groove, and the end of the baffle 120 facing the opening 1121 is provided with a push rod 123, and the push rod 123 extends out of the opening 1121. The push rod 123 is used to push the baffle 120 to slide relative to the valve body 110 along the first direction, which can improve the convenience of adjusting the opening of the first vent 1111.

[0068] In the above embodiment, the push rod 123 can be driven to move in translation manually or by a driving device, and the driving device can be an electric or pneumatic driving member.

[0069] In one embodiment, the air valve 100 further includes a driving device, which is in transmission connection with the baffle 120 to drive the baffle 120 to slide along the first direction relative to the valve body 110. Specifically, the driving device is in transmission connection with the baffle 120 via the push rod 123.

[0070] On the basis of the above embodiments, in one embodiment, the air valve 100 also includes a wind speed sensor and a controller, the wind speed sensor is arranged on one side of the ventilation area 111, and is used to measure the wind speed of the first vent 1111, the input end of the controller is electrically connected to the wind speed sensor, and the output end of the controller is electrically connected to the driving device, and the controller controls the start and stop of the driving device according to the measurement result of the wind speed sensor.

[0071] During use, when the airflow passes through the first vent 1111, the wind speed sensor detects the wind speed and transmits the wind speed signal to the controller. The controller compares the preset position of the baffle 120 corresponding to the wind speed signal with the current actual position. If the preset position does not match the actual position, the controller controls the drive device to drive the baffle 120 to move to the preset position. It can be understood that when the wind speed increases, the controller controls the drive device to drive the baffle 120 to move, so that the opening of the first vent 1111 is reduced to a suitable range; when the wind speed decreases, the controller controls the drive device to drive the baffle 120 to move, so that the opening of the first vent 1111 is increased to a suitable range.

[0072] In the above embodiment, by cooperating the wind speed sensor, the controller and the driving device, the position of the baffle 120 can be automatically adjusted, that is, the intelligent control of the air volume of the vent of the air device is realized, and the overall flexibility is high.

[0073] See also Figure 5 In one embodiment, a mounting portion 113 is provided outside the ventilation area 111, and the mounting portion 113 extends along the circumference of the ventilation area 111 to form a frame shape. The mounting portion 113 and the boss 112 are respectively located at the inner and outer sides of the ventilation area 111. Specifically, an outer flange is formed at one end of the mounting portion 113 facing away from the ventilation area 111, and the outer flange extends from the end of the mounting portion 113 away from the ventilation area 111. In this embodiment, the external ventilation pipe can be connected to the air valve 100 through the mounting portion 113, so as to facilitate the input or output of gas.

[0074] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
