[0002] A baby carrier is a childcare aid designed as a chair that can be strapped to the waist of a parent or caregiver. It primarily uses a belt to distribute the baby's weight to the waist and surrounding area, thereby reducing pressure on the arms and back of the parent or caregiver.

[0003] However, prolonged use of a hip seat, especially in hot and humid weather, can cause discomfort for users such as parents or infants, affecting their mood and overall experience. Traditional hip seats primarily address this issue through passive cooling methods, such as using cotton fabric for sweat absorption and heat dissipation. However, this method still results in stuffiness after extended use, is ineffective in heat dissipation, and lacks proactive and intelligent features.

[0004] Therefore, there is an urgent need to propose a breathable airflow guiding structure and a waist stool that can achieve active heat dissipation. Summary of the Invention

[0049] Please see Figures 1 to 12 This utility model embodiment provides a breathable airflow guiding structure suitable for waist stools, including: a breathable component 1, a housing 2, and a heat dissipation component 3 disposed on the housing 2.

[0050] In one embodiment, the breathable member 1 is provided with a breathable portion 11 extending through its thickness. The breathable portion 11 is provided with a contact surface 111 facing the back of the infant and a human body contact surface 112 disposed opposite to the contact surface 111. The contact surface 111 and / or the human body contact surface 112 are provided with a plurality of breathable holes 113.

[0051] Thickness can be understood as... Figure 3 The distance between the contact surface 111 and the human body contact surface 112 shown.

[0052] It should be noted that the contact surface 111 is the area on the breathable component 1 that directly contacts the skin of the baby's back, and its outline is adapted to the curve of the baby's back; the human body contact surface 112 is the surface on the breathable component 1 that directly contacts the body of the user, such as the parent. For example, the human body contact surface 112 refers to the surface on the breathable component 1 that directly contacts the skin of the wearer's waist and abdomen, and its outline is adapted to the curve of the human waist and abdomen.

[0053] It is worth mentioning that the contact surface 111 and / or the human body contact surface 112 are provided with a plurality of ventilation holes 113, including: the contact surface 111 is provided with a plurality of ventilation holes 113, or the human body contact surface 112 is provided with a plurality of ventilation holes 113; or, both the contact surface 111 and the human body contact surface 112 are provided with a plurality of ventilation holes. Providing a plurality of ventilation holes 113 only on the contact surface 111 allows for heat dissipation from the baby's back; providing a plurality of ventilation holes 113 only on the human body contact surface 112 allows for heat dissipation from the wearer's (e.g., the parent's) back side corresponding to the baby's back; and providing a plurality of ventilation holes 113 on both the contact surface 111 and the human body contact surface 112 allows for heat dissipation from both the baby's back and the wearer's back side corresponding to the baby's back.

[0054] In one embodiment, the ventilation holes 113 are distributed on the contact surface 111 and / or the human body contact surface 112, and their distribution includes: uniform distribution in all areas; non-uniform distribution in all areas; or uniform distribution in some areas and non-uniform distribution in some areas.

[0055] It should be noted that uniformly distributing the ventilation holes 113 on the contact surface 111 and / or the human body contact surface 112 facilitates processing and manufacturing; while non-uniformly distributing the ventilation holes 113 on the contact surface 111 and / or the human body contact surface 112 allows for the placement of the ventilation holes 113 according to actual needs; and while some areas of the ventilation holes 113 are evenly distributed and some areas are non-uniformly distributed on the contact surface 111 and / or the human body contact surface 112, ventilation holes 113 can be evenly placed in areas with more sweat, such as the middle of an infant's back, and non-uniformly placed near the arms.

[0056] In an alternative embodiment, a plurality of vents 113 provided on the contact surface 111 and / or the human body contact surface 112 may at least partially penetrate the contact surface 111 and the human body contact surface 112.

[0057] Specifically, the ventilation holes 113 at least partially penetrate the contact surface 111 and the human body contact surface 112, including: all ventilation holes 113 penetrating the contact surface 111 and the human body contact surface 112; or, some ventilation holes 113 penetrating the contact surface 111 and the human body contact surface 112, while the remaining portion does not penetrate the contact surface 111 and the human body contact surface 112, such as being provided on the contact surface 111 or the human body contact surface 112.

[0058] The ventilation hole 113 penetrates the contact surface 111 and the human body contact surface 112, which can be understood as follows: Figure 5 The air vent 113 of the contact surface 111 and the human body contact surface 112 are the same.

[0059] In another alternative embodiment, the vent 113 does not penetrate the contact surface 111 and the body-fitting surface 112. Alternatively, the vent 113 penetrates the contact surface 111 but not the body-fitting surface 112; or, the vent 113 does not penetrate the contact surface 111 but penetrates the body-fitting surface 112.

[0060] It should be noted that the contact surface 111 is provided with a vent hole 113 and the human body contact surface 112 is provided with a vent hole 113, but the vent holes 113 on the two surfaces are independent of each other.

[0061] It is worth mentioning that by providing multiple ventilation holes 113 on the contact surface 111 and / or the body-contact surface 112, heat dissipation can be achieved on the back of the infant and / or on the side of the parent relative to the infant's back. This limits heat dissipation to the back of the infant and / or on the side of the wearer (such as the parent) relative to the infant's back. When dissipating heat on the back of the infant, discomfort such as rashes caused by overheating is avoided. When dissipating heat on the side of the parent relative to the infant's back (i.e., the contact area between the parent and infant's backs), heat can be dissipated from this contact area, reducing its temperature and making both the wearer and the infant feel comfortable, thus improving the wearer's experience. Simultaneously dissipating heat on both the back of the infant and the side of the parent relative to the infant's back offers the advantage of considering both the infant and the parent's comfort and satisfaction.

[0062] In one embodiment, the housing 2 is provided with an air inlet 21 and an air outlet 22, and the ventilator 1 is connected to the housing 2.

[0063] In one alternative, the breathable component 1 is detachably connected to the housing 2. This detachable connection allows the breathable component 1 to be removed from the housing 2 when not in use, such as in hot weather like winter. It can also be removed for cleaning after use to maintain cleanliness. The detachable connection method can include snap-fit ​​and threaded connections.

[0064] In one alternative approach, the breathable element 1 is fixedly connected to the housing 2, and the fixed connection, such as by bonding, is not limited here.

[0065] In one embodiment, the heat dissipation component 3 is disposed inside the housing 2 and configured to drive airflow, such that a first airflow channel 4 is formed between the vent 113 and the air inlet 21, and a second airflow channel 5 is formed between the air inlet 21 and the air outlet 22.

[0066] The heat dissipation component 3 can be a fan or a miniature air pump, which is fixedly installed inside the housing 2. Specifically, the heat dissipation component 3, such as a fan or a miniature air pump, can be fixedly installed inside the housing 2 by means of a bracket or the like.

[0067] In an alternative embodiment, the first airflow channel 4 includes a first guide section 41 and a second guide section 42; the first guide section 41 is formed by interconnecting flow channels 411 between a plurality of the vent holes 113, the interconnecting flow channels 411 including at least one guide groove 4111; the second guide section 42 is formed by connecting at least one selected vent hole 1131 of the first guide section 41 and the air inlet 21.

[0068] The interconnected flow channel 411 can be understood as a physical channel or path formed between the vent holes 113 that allows airflow to flow between each other.

[0069] It should be noted that the interconnecting flow channel 411 includes at least one guide groove 4111, that is, the guide groove 4111 of the interconnecting flow channel 411 can be as follows: Figure 9 The number shown can be one or more, such as two or three, and there is no restriction here.

[0070] In one embodiment, two guide channels of interconnected flow channel 411 are described exemplarily, i.e., as follows Figure 10 and 11 As shown, the flow guide 4111 includes a first flow guide 41111 and a second flow guide 41112.

[0071] In an optional manner, such as Figure 10 As shown, the first guide channel 41111 connects the first vent 1132 and the second vent 1133; the second guide channel 41112 connects the second vent 1133 and the third vent 1134.

[0072] In an optional manner, such as Figure 10 As shown, the first guide channel 41111 connects the first vent 1132 and the second vent 1133; the second guide channel 41112 connects the third vent 1134 and the fourth vent 1135.

[0073] It should be noted that the selected vent 1131 is a vent selected from the plurality of vents 113 forming the interconnected flow channel 411. In one feasible manner, such as... Figure 12 As shown, the vent 113 can be a vent near the air inlet 21. Of course, the vent 1131 can also be a vent not near the air inlet 21. The vent 1131 can be pre-set according to actual needs. For example, after the vent is selected, a second guide section 42 can be set between the selected vent 1131 and the air inlet 21.

[0074] It is worth mentioning that, Figures 9 to 12 Only one interconnecting flow channel 411 is illustrated. In another embodiment, the first guide section 41 may also include multiple interconnecting flow channels 411, such as two or three, each of which is formed by at least one guide groove 4111. The number of vent holes 113 forming each interconnecting flow channel 411 is also not limited, for example, two, three, or four. That is, the first guide section 41 within the vent 11 contains multiple interconnecting flow channels 411, and the paths formed by each interconnecting flow channel 411 can be varied, which is not limited here. This embodiment improves heat dissipation efficiency by providing multiple interconnecting flow channels 411.

[0075] In one embodiment, the second airflow channel 5 is formed by sequentially connecting a third guide section 51, a heat dissipation component 3, and a fourth guide section 52; wherein, the third guide section 51 connects the air inlet 21 with the air inlet end of the heat dissipation component 3; and the fourth guide section 53 connects the air outlet end of the heat dissipation component 3 with the air outlet 22.

[0076] In one embodiment, the breathable element 1 is a textile material having the breathable holes 113. Specifically, the breathable element 1 is any one of mesh fabric, nonwoven fabric, knitted fabric, and woven fabric; of course, in other embodiments, the breathable element 1 may also be other materials, and there is no limitation here.

[0077] This utility model provides a breathable airflow guiding structure, which, by setting breathable components, air inlets, air outlets and heat dissipation components, forms an active heat dissipation structure that is different from traditional waist stools. It can solve the problem of the waist stool being stuffy and affecting the mood and use experience of users such as parents or infants, and can actively dissipate heat, thus having an intelligent feature.

[0078] Furthermore, the breathable airflow guiding structure of this utility model embodiment provides a breathable portion that extends through the thickness of the breathable component. Multiple air vents are formed on the contact surface of the breathable portion facing the baby's back and / or on the human body contact surface opposite to the contact surface, further dissipating heat from the baby's back and / or the area where the parents' backs are relative to the baby's back. When dissipating heat from the baby's back, discomfort such as rashes caused by stuffiness can be avoided. When dissipating heat from the area where the parents' backs are relative to the baby's back (i.e., the contact area between the parents' and baby's backs), the parents' comfort is improved. Simultaneously dissipating heat from both the baby's back and the area where the parents' backs are relative to the baby's back caters to both the baby and the parents, improving the comfort and satisfaction of both.

[0079] Please see Figures 3 to 5 This utility model provides a waist stool, which includes a seat cushion 200 and a breathable airflow guiding structure as described above. The breathable component 1 is disposed on the seat cushion 200, specifically on the upper surface 201 of the seat cushion 200.

[0080] In one embodiment, a baby carrier further includes a support belt, which may include at least one of a shoulder strap and a waist belt. When the support belt includes a waist belt, the waist belt is located on both sides of the seat cushion 200 for wrapping around the waist of the wearer. The waist belts located on both sides of the seat cushion 1 can be fixed together by means of buckles, Velcro, or adjustable straps. When the support belt includes a shoulder strap, the shoulder strap can be located on the seat cushion 200, specifically by means of sewing or other methods. The back strap is fixed through the shoulder, which can prevent the baby carrier from tilting forward or sliding sideways when the baby moves or the wearer bends over. When the support belt includes both a shoulder strap and a waist belt, the coordinated setting of the waist belt and the back strap can not only significantly reduce the burden on the waist, but also help to fix the baby carrier, prevent the baby carrier from shaking or sliding down when walking or moving, ensure the baby's safety, improve safety, and also make the weight distribution more even, reduce local pressure, and improve the wearer's comfort.

[0081] A waist stool according to an embodiment of the present invention is provided with the above-mentioned breathable airflow guiding structure, which can actively dissipate heat, improve the experience of parents, and further dissipate heat on the back of the baby and / or the position of the parents relative to the back of the baby, avoiding discomfort symptoms such as rashes on the back of the baby due to stuffiness, thus improving the satisfaction and comfort of parents and / or babies.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
