[0032] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0033] Please refer to Figure 1 and Figure 2 The seat air blowing mechanism 100 and the child safety seat provided in the embodiment of the utility model can solve the above-mentioned problems, which will be described in detail below.

[0034] The seat blowing mechanism 100 includes a headrest 110 and a blowing piece 120 connected to each other; wherein the blowing piece 120 has a first air outlet 1201 and a second air outlet 1202, the first air outlet 1201 is arranged toward the headrest 110 and is used to blow air to the human head, and the second air outlet 1202 is used to blow air to the human back.

[0035] In the working state, the blowing member 120 can output airflow through the first air outlet 1201, and by limiting the direction of the first air outlet 1201, the airflow can produce a blowing effect on the head of the human body, thereby achieving cooling and heat dissipation of the head. By setting the second air outlet 1202, it is possible to achieve cooling and heat dissipation of the head and back at the same time.

[0036] refer to Figure 1 In order to improve the blowing effect on the human head, the number of the first air outlets 1201 can be at least two, and the arrangement direction of the at least two first air outlets 1201 is perpendicular to the direction of the first air outlet 1201.

[0037] In this embodiment, the first air outlets 1201 are arranged in a straight line and can be regarded as a horizontal direction, and the orientation of the first air outlets 1201 can be regarded as a direction from bottom to top in the height direction.

[0038] Of course, in other embodiments of the present invention, in order to enable different positions of the head to experience different blowing effects, the first air outlets 1201 can also be arranged in an arc, and the first air outlet 1201 in the middle of the arc can be set higher than the first air outlets 1201 on both sides, or the first air outlet 1201 in the middle of the arc can be set lower than the first air outlets 1201 on both sides. There is no limitation on the specific arrangement of the multiple first air outlets 1201.

[0039] refer to Figure 1 and Figure 2 The blowing member 120 includes a blowing shell 121, a first fan 122 and a second fan 123. The blowing shell 121 is connected to the headrest 110. The first fan 122 and the second fan 123 are both accommodated in the blowing shell 121. The first air outlet 1201 is opened in the blowing shell 121 and is connected to the first fan 122. The second air outlet 1202 is opened in the blowing shell 121 and is connected to the second fan 123.

[0040] During installation, the first fan 122 and the second fan 123 can be accommodated in the blowing shell 121. On the one hand, the blowing shell 121 can shield and protect the two. On the other hand, the blowing shell 121 can isolate the first fan 122 and the second fan to prevent them from being too close to the human body and posing a safety hazard.

[0041] Furthermore, the first air outlet 1201 and the second air outlet 1202 are connected to the first fan 122 and the second fan 123 respectively, so that the airflows generated by the two air outlets have different sources, which helps to improve the diversion effect and avoid the mutual influence between the two and reduce the blowing effect.

[0042] In addition, because there is a certain distance between the first air outlet 1201 and the headrest 110, that is, there is a sufficient distance between the first air outlet 1201 and the human head, in order to make the output airflow velocity and pressure sufficient, the first fan 122 can be a blower fan, and the blowing housing 121 is provided with an air suction port 1203, and the air suction port 1203 is arranged corresponding to the first fan 122. It can be understood that the first fan 122 is a blower fan, which sucks airflow through the air suction port 1203 and then outputs it through the first air outlet 1201, so that the output airflow has a sufficient velocity and pressure.

[0043] In the present embodiment, the number of the first fans 122 is one; of course, in other embodiments of the present invention, the number of the first fans 122 may be two, three, four, etc. The arrangement direction of at least two first fans 122 may be consistent with the arrangement direction of the first air outlet 1201, or may be perpendicular to the arrangement direction of the first air outlet 1201. Multiple first fans 122 may also be arranged in an array. There is no limitation on the specific number and arrangement of the first fans 122.

[0044] refer to Figure 1 and Figure 2 The first air outlet 1201 is located on the upper side of the first fan 122 , and the air intake 1203 is arranged at the same height as the first fan 122 .

[0045] In the above technical solution, by limiting the relative positions of the first air outlet 1201, the air intake port 1203 and the first fan 122, the airflow can quickly enter the first fan 122 when entering from the air intake port 1203, and then be pressurized by the first fan 122 and then output from the first air outlet 1201, thereby ensuring the air outlet effect while increasing the air outlet rate by reducing the transmission path of the airflow.

[0046] It should be noted that, because the first fan 122 has a certain extension dimension in the height direction, and usually there are multiple air intake ports 1203, the equal height setting of the air intake port 1203 and the first fan 122 includes the air intake port 1203 located at a high place being equal to the top position of the first fan 122, and the air intake port 1203 located at a low place being equal to the bottom position of the first fan 122, which can be understood as the air intake port 1203 and the first fan 122 being equal in height.

[0047] refer to Figure 1 and Figure 2 The air inlet 1203 is arranged on a side of the blowing housing 121 close to the human body. In addition, the air inlet 1203 can correspond to the neck position of the human body.

[0048] When it is necessary to inhale air, air can be inhaled from near the human neck through the air inlet 1203. On the one hand, the volume of the human neck is smaller than that of the head and the back, so there will not be too much obstruction when inhaling air; on the other hand, the airflow effect generated when inhaling air can also take away the heat from the neck, thereby having a certain heat dissipation and cooling effect on the neck position.

[0049] refer to Figure 1 and Figure 2In order to prevent the air intake port 1203 from directly taking away the airflow output by the second air outlet 1202 when working, the distance between the air intake port 1203 and the first air outlet 1201 can be made smaller than the distance between the air intake port 1203 and the second air outlet 1202. By maintaining a sufficient safety distance between the air intake port 1203 and the second air outlet 1202, the negative impact of the air outlet effect of the second air outlet 1202 when the air intake port 1203 is sucking air can be avoided.

[0050] refer to Figure 1 and Figure 2 The second fan 123 and the second air outlet 1202 are arranged at the same height. By limiting the relative position of the second air outlet 1202 and the second fan 123, the airflow generated by the second fan 123 can be quickly discharged from the second air outlet 1202, and the air outlet rate can be increased by reducing the transmission path of the airflow in the blowing shell 121.

[0051] It should be noted that, because the second fan 123 has a certain extension dimension in the height direction, and usually there are multiple second air outlets 1202, the equal height setting of the second air outlet 1202 and the second fan 123 includes the second air outlet 1202 located at a high place being equal to the top position of the second fan 123, and the second air outlet 1202 located at a low place being equal to the bottom position of the second fan 123, which can be understood as the second air outlet 1202 and the second fan 123 being equal in height.

[0052] In this embodiment, the second fan 123 may be a fan, which drives the peripheral air flow by the rotation of the fan blades, and the flowing air flow may be output through the second air outlet 1202 .

[0053] Of course, in other embodiments of the present invention, the second fan 123 may also be a blower, and corresponding air inlets may be opened on both sides of the blowing shell 121, so that air is taken in through the air inlet, pressurized by the second fan 123, and then blown out through the second air outlet 1202.

[0054] refer to Figure 1 and Figure 2 In order to improve the blowing effect on the back of the human body, the number of the second fans 123 can be two, and the arrangement direction of the two second fans 123 is perpendicular to the direction of the first air outlet 1201.

[0055] In this embodiment, the two second fans 123 are arranged in a straight line and can be regarded as a horizontal direction.

[0056] Of course, in other embodiments of the present invention, the number of the second fans 123 can be one, three, four, etc. When the number is greater than two, the second fans 123 can be arranged in a straight line, in a curve, or in an array. There is no limitation on the specific number and arrangement of the second fans 123.

[0057] The embodiment of the utility model also provides a child safety seat, including a seat air-drying mechanism 100, and also including a base, a turntable, a seat cushion, a back cushion and a leg pad. The base is located at the lowest side of the child safety seat and is used to prevent the child from sitting on the car seat. The back cushion is sleeved on the outside of the air-drying member 120. The back cushion is usually made of fabric, so it has a certain ventilation effect and will not block the wind. The seat cushion is connected to the end of the back cushion away from the headrest 110, and the leg pad is connected to the end of the seat cushion away from the back cushion. The turntable is connected between the base and the seat cushion. The turntable can drive the seat cushion, the leg pad, the back cushion and the seat air-drying mechanism 100 to rotate relative to the base under the action of an external force, so as to adjust the sitting posture of multiple children in different directions.

[0058] The child safety seat comprises a seat air blowing mechanism 100 , which has all the functions of the seat air blowing mechanism 100 .

[0059] In summary, the seat air blowing mechanism 100 and the child safety seat provided by the embodiment of the utility model have at least the following advantages:

[0060] (1) The blowing member 120 can output airflow through the first air outlet 1201 and the second air outlet 1202. The second air outlet 1202 produces a blowing effect on the back of the human body, and by limiting the direction of the first air outlet 1201, the airflow can produce a blowing effect on the head of the human body, thereby achieving cooling and heat dissipation of the head and back at the same time;

[0061] (2) The blowing shell 121 can be provided with an air suction port 1203, and the air suction port 1203 is arranged corresponding to the first fan 122. The air suction port 1203 draws air into the first fan 122, and then the air is output from the first air outlet 1201, so that the output air flow has a sufficient flow rate and flow pressure, thereby ensuring the blowing effect on the human head.

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
