Detailed Embodiments

[0024] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] Please refer to Figure 1 and Figure 2 , the present invention provides an air supply device, which includes: a housing 1, and an air storage cavity 10 is provided inside the housing 1; an air outlet 20 is provided on the housing 1, and the air outlet 20 communicates the air storage cavity 10 with the external space of the housing 1; a flexible film 2, which is deformably arranged; a knocking structure 3, which has a movable knocking part, when the knocking structure 3 acts, the knocking part knocks on the flexible film 2 to make the flexible film 2 deform, and the flexible film 2 drives the gas in the air storage cavity 10 to move to the outside of the housing 1 through the air outlet 20.

[0026] The air supply device of the present invention includes: a housing 1, a flexible membrane 2, and a knocking structure 3. The interior of the housing 1 has an air storage cavity 10; an air outlet 20 is provided on the housing 1, and the air outlet 20 communicates the air storage cavity 10 with the external space of the housing 1; the flexible membrane 2 is deformably arranged; the knocking structure 3 has a movable knocking part. When the knocking structure 3 operates, the knocking part knocks on the flexible membrane 2 to make the flexible membrane 2 deform, and the flexible membrane 2 drives the gas in the air storage cavity 10 to move to the outside of the housing 1 through the air outlet 20. By adopting this structural design, the regular deformation of the flexible membrane 2 is caused by the knocking of the knocking structure 3 on the flexible membrane 2, so that the flexible membrane 2 can drive the gas in contact with it, and part of the gas in the housing 1 is transported to the outside of the housing 1 through the air outlet 20, which can make the blown air more soothing, effectively reduce the blowing feeling of the user, and solve the problem of poor air supply comfort of the air supply device in the prior art.

[0027] Specifically, when the knocking structure 3 regularly knocks on the flexible membrane 2, the flexible membrane 2 vibrates, squeezes the gas in the air storage cavity 10 to flow out through the air outlet 20, forming a number of air vortices 100. During the process of moving along the original trajectory, the air vortices 100 gradually mix with the surrounding air and spread and become larger, and the wind speed will be further reduced. When blowing on the human body, the effect of gentle wind can be achieved, significantly reducing the blowing feeling of the user, effectively improving the air supply comfort, and when applied to structures such as air conditioners, the occurrence probability of air conditioner diseases can be effectively reduced.

[0028] It should be noted that the above-mentioned knocking is not limited to the conventional meaning of knocking. It should be understood that as long as the knocking structure 3 can drive the flexible membrane 2 to deform. In actual implementation, the knocking part of the knocking structure 3 can be arranged at an interval from the flexible membrane 2 or connected to the flexible membrane 2. When the two are arranged at an interval, the knocking part only plays a knocking role when approaching the flexible membrane 2. When the two are connected, the knocking part can drive the flexible membrane 2 to move during the reciprocating process of regular movement, producing an effect similar to knocking, so as to better drive the flexible membrane 2 to vibrate.

[0029] Specifically, an air inlet is provided on the housing 1, and the flexible membrane 2 covers the air inlet; a plurality of air inlet holes are provided on the flexible membrane 2.

[0030] By adopting the above settings, when the air supply device is in use, the gas enters the air storage cavity 10 of the housing 1 through the air inlet holes on the flexible membrane 2, which can effectively reduce the disturbance of the gas in the air storage cavity 10 by the incoming air, and keep the gas in the air storage cavity 10 in a relatively calm state as much as possible. Therefore, when the knocking structure 3 knocks on the flexible membrane 2, it is easier to generate air vortices 100, thereby improving the air supply comfort.

[0031] In specific implementation, according to the actual situation and requirements, the flexible film 2 can completely block the air inlet or block a part of the air inlet.

[0032] Specifically, the air outlet 20 is a circular hole. By setting the air outlet 20 as a circular hole, when the flexible film 2 deforms to drive the gas to be regularly discharged through the air outlet 20, the discharged gas is more likely to form an air vortex 100, thereby being more likely to spread and mix with the surrounding air, making the air supply experience better.

[0033] Of course, the air outlet 20 can also be a structure of other shapes, such as a rectangle, an ellipse, a triangle or other irregular shapes, as long as the gas can pass through it. Of course, these shaped air outlets 20 are not conducive to the generation of the air vortex 100, and are likely to affect the mixing of the air outlet with the surrounding air, making the wind feeling more obvious and being disadvantageous to the air supply experience.

[0034] For better air supply, a plurality of air outlets 20 are provided. In this embodiment, in order to make the air supply more uniform, the plurality of air outlets 20 are arranged in multiple rows and columns.

[0035] Specifically, there are a plurality of air outlets 20, and the distances from the plurality of air outlets 20 to the flexible film 2 are all different; at least part of the air storage cavity 10 is a constricted cavity, and along the direction away from the flexible film 2, the area of the flow cross-section of the constricted cavity gradually decreases.

[0036] By adopting the above settings, the flow cross-section of the constricted cavity, that is, the cross-section perpendicular to the direction of the gas entering the air storage cavity 10, by gradually reducing the flow cross-section of the constricted cavity, can enable the gas at the air outlet 20 farther from the flexible film 2 to flow out more fully to the outside of the air storage cavity 10 when being squeezed, so as to ensure the uniformity of the air supply of the plurality of air outlets 20 as much as possible, and finally make the air supply of the air supply device more gentle and improve the air supply experience.

[0037] Specifically, the air storage cavity 10 has a first inner wall surface 101 and a second inner wall surface 102 arranged opposite to each other, the air outlet 20 extends to the first inner wall surface, and both the first inner wall surface 101 and the second inner wall surface 102 are arc-shaped surfaces.

[0038] By adopting the above settings, the gas can flow more smoothly along the first inner wall surface 101 and the second inner wall surface 102, which is not only beneficial to improving the air supply stability, but also enables the gas to be more fully and uniformly distributed in the air storage cavity 10, thereby improving the uniformity and consistency of the air supply at each position of the air supply device.

[0039] Specifically, the knocking structure 3 includes a motor and an eccentric member, the eccentric member is connected to the output shaft of the motor, and the knocking part is at least part of the eccentric member.

[0040] Of course, the tapping structure 3 is not limited to the above-mentioned structure, as long as it can achieve the effect of driving the flexible membrane 2 to deform. For example, the tapping structure 3 can also be a vibrator, which is connected to the flexible membrane 2, thereby driving the flexible membrane 2 to deform. For another example, the tapping structure 3 includes a micro cylinder, which drives the flexible membrane 2 to deform through the reciprocating motion of the micro cylinder.

[0041] Please refer to Figures 3 to 5 The present invention also provides an air-conditioning indoor unit, which includes: a main body part, which includes a casing 4, a heat exchanger 5 and a fan 6, the heat exchanger 5 and the fan 6 are arranged inside the casing 4, and the casing 4 is provided with an air outlet 41; an air supply device, which is the above-mentioned air supply device, and is arranged at the air outlet 41 of the main body part so that the gas flowing out of the air outlet 41 is delivered through the air supply device.

[0042] Specifically, the air-conditioning indoor unit includes a wind shield assembly 7, at least part of which is movably arranged to have a first state and a second state; when the wind shield assembly 7 is in the first state, the wind shield assembly 7 separates the air outlet 41 from the external space of the air-conditioning indoor unit, and the air outlet 41 is connected to the air storage chamber 10 of the shell 1; when the wind shield assembly 7 is in the second state, the wind shield assembly 7 separates the air outlet 41 from the air storage chamber 10 of the shell 1, and the air outlet 41 is connected to the external space of the air-conditioning indoor unit.

[0043] Specifically, the wind shield assembly 7 includes an upper wind shield plate 71 and a lower wind shield plate 72, and both the upper wind shield plate 71 and the lower wind shield plate 72 are rotatably arranged; when the wind shield assembly 7 is in a first state, the upper wind shield plate 71 and the lower wind shield plate 72 are connected to separate the air outlet 41 from the external space of the air-conditioning indoor unit; when the wind shield assembly 7 is in a second state, the upper wind shield plate 71 separates the air outlet 41 from the air storage chamber 10 of the shell 1, and the gas discharged from the air outlet 41 is discharged to the outside of the air-conditioning indoor unit through the gap between the upper wind shield plate 71 and the lower wind shield plate 72; wherein, the length of the upper wind shield plate 71 is greater than the length of the lower wind shield plate 72.

[0044] It should be noted that, when the air conditioner indoor unit is normally installed and used, when the wind shield assembly 7 is in the second state, at least a portion of the upper wind shield plate 71 is located above the lower wind shield plate 72 .

[0045] In addition, the present invention further provides an air conditioner, which includes the above-mentioned air conditioner indoor unit.
