Where there is no conflict, the various features in the embodiments and examples of this utility model can be combined with each other, all of which are within the protection scope of this utility model.

[0038] Please refer to Figures 1 to 10. This embodiment of the utility model provides a waist stool, including a seat cushion 1, a support belt (not shown in the figure) and a heat dissipation device 2.

[0039] In one embodiment, the seat cushion 1 has an upper surface 11 that supports the infant, and the seat cushion 1 is provided with a filling 12.

[0040] The filling material 12 may be composed of at least one of the following soft filling materials: memory foam, high-density sponge, natural latex, PP cotton, down, air fiber, and natural cotton. Of course, the filling material 12 may also be composed of other filling materials with soft properties, and there are no restrictions on this.

[0041] It should be noted that the seat cushion 1 also includes a protective sleeve (not shown in the figure) that covers the filling 12. The protective sleeve allows the filling 12 to be placed inside the seat cushion 1, protecting the filling 12 and thus keeping the filling 12 clean and tidy.

[0042] In one embodiment, as shown in Figures 4, 8, 9 and 10, the filler 12 includes an upper side 122, a front side 123, a lower side 124 and a rear side 121 facing the human body.

[0043] The rear side 121 is an irregular plane, specifically an uneven plane as shown in Figures 4, 8 and 10. The shape of the rear side 121 can be determined by the shape of one side of the adjacent component. In this embodiment, it can be determined by the shape of the side of the body 22 of the heat dissipation device 2 adjacent to the rear side 121. Through the adaptation of the two, the filler 12 and the body 21 can be better assembled together for heat dissipation, and the problem of noise generation or collapse of the filler 12 due to the gap between the two can also be avoided.

[0044] It should be noted that the front side 123 and the lower side 124 are connected to form a smooth arc surface at the connection. Of course, it can also be understood that the front side 123 and the lower side 124 are formed by a single arc surface, and this is not a limitation.

[0045] In one embodiment, the rear side surface 121 is composed of a first sub-side surface 1211, a first sub-connecting surface 1212, a second sub-side surface 1213, a second sub-connecting surface 1214, and a third sub-side surface 1215. The first sub-side surface 1211 and the second sub-side surface 1213 are connected through the first sub-connecting surface 1212, and the second sub-side surface 1213 and the third sub-side surface 1215 are connected through the second sub-connecting surface 1214. The first sub-side surface 1211 and the third sub-side surface 1215 protrude in a direction away from the second sub-side surface 1213.

[0046] It should be noted that in this embodiment, the first sub-side surface 1211 and the third sub-side surface 1215 protrude away from the second sub-side surface 1213, forming a hollowed-out bottom (i.e., lower side surface 124) design as shown in Figures 8 to 10. This hollowed-out design allows the air outlet 222 located at the lower end of the main body 22 to be exposed to the seat cushion 1, that is, the air outlet 222 is exposed from the bottom of the filling body 12, thus achieving heat dissipation. Compared with a design where the air outlet 222 is not exposed, this method avoids the situation where heat cannot be dissipated inside the seat cushion 1 or is dissipated in a timely manner, resulting in the seat cushion 1 becoming too hot for the buttocks.

[0047] In one embodiment, the second sub-side surface 1213 includes a second upper sub-side surface 12131 and a second lower sub-side surface 12132, and the third sub-side surface 1215 includes a third upper sub-side surface 12151 and a third lower sub-side surface 12152. The second lower sub-side surface 12132 protrudes towards the body 22 of the heat dissipation device 2; the third lower sub-side surface 12152 and the third upper sub-side surface 12151 protrude away from the second sub-side surface 1213, but the third lower sub-side surface 12152 protrudes a greater distance to form a stepped surface, thereby supporting part of the outer shell of the body 22 of the heat dissipation component 2 and exposing its air outlet 222 at the bottom of the seat cushion 1. By designing the second sub-side surface 1213 and the third sub-side surface 1215 as concave and convex surfaces, this embodiment allows the filler 12 to be fitted and assembled with the outer shell of the heat dissipation device 22. This not only dissipates the heat generated by the baby and wearer to the external environment, but also avoids material waste and reduces costs due to the fitted assembly.

[0048] In one embodiment, the second sub-side surface 1213 includes a second upper sub-side surface 12131 and a second lower sub-side surface 12132, and the third sub-side surface 1215 includes a third upper sub-side surface 12151 and a third lower sub-side surface 12152. The second upper sub-side surface 12131 and the second lower sub-side surface 12132 are interlocked by a concave-convex structure, and the third upper sub-side surface 12151 and the third lower sub-side surface 12152 are also interlocked by a concave-convex structure. By adopting a concave-convex design for the second sub-side surface 1213 and the third sub-side surface 1215, this embodiment allows the rear side surface 121 of the filler 12 to be fitted and assembled with the heat dissipation device 2, etc., which facilitates assembly and reduces costs.

[0049] In one alternative approach, the third upper sub-side 12151 can be an arc surface, and the second upper sub-side 12131 can also be an arc surface. Through the design of the arc surfaces, they are connected to the third lower sub-side 12152 and the second lower sub-side 12132 respectively.

[0050] In another alternative approach, the second upper sub-side surface 12131 may not be a curved surface. By providing a connecting surface between the second upper sub-side surface 12131 and the second lower sub-side surface 12132, the second upper sub-side surface 12131 and the second lower sub-side surface 12132 can be connected together, thereby forming a concave-convex surface. Similarly, a connecting surface can be provided between the third upper sub-side surface 12151 and the third lower sub-side surface 12152 to connect the third upper sub-side surface 12151 and the third lower sub-side surface 12152 together.

[0051] In one embodiment, the lumbar stool further includes a support strap (not shown) connected to the seat cushion 1.

[0052] In one alternative embodiment, the support belt is a waist belt, which can be located on both sides of the seat cushion 1 and used to wrap around the waist of the person. The waist belts located on both sides of the seat cushion 1 can be fixed together using methods such as buckles, Velcro, or adjustable straps.

[0053] In an alternative embodiment, the support strap is a shoulder strap, which may be specifically located on the seat cushion 1, such as on the upper surface of the seat cushion 1. The shoulder strap is fixed by the shoulder, which can prevent the waist stool from tilting forward or sliding sideways due to the baby's movement or the wearer bending over.

[0054] In one alternative, the support belt may include both a waist belt and shoulder straps. The coordinated arrangement of the waist belt and shoulder straps can not only significantly reduce the burden on the waist, but also help to fix the baby carrier, preventing it from swaying or slipping during walking or activity, thus ensuring the baby's safety and improving safety. It can also make the weight distribution more even, reduce local pressure, and improve the wearer's comfort.

[0055] It should be noted that the human body described in this utility model can be understood as the person using the waist stool to care for the baby, that is, the wearer, who can be the baby's parents or other caregivers.

[0056] In one embodiment, the heat dissipation device 2 has a vent 21, a body 22 disposed on the rear side 121 of the filler 12, and a heat dissipation component 23 disposed within the body 22.

[0057] The breathable component 21 is provided on the upper surface 11 of the seat cushion 1, and the breathable component 21 has a breathable hole 211 facing the baby. The body 22 is provided with an air inlet 221 and an air outlet 222, and the breathable hole 211 is connected to the air inlet 221 and the air outlet 222.

[0058] In other words, air can enter through the vent 211, pass through the air inlet 221, and be discharged to the external environment through the air outlet 222.

[0059] This utility model discloses a waist stool with a heat dissipation device. The wearer can activate the heat dissipation function when using the waist stool, which improves the wearer's comfort and satisfaction, resulting in a better user experience.

[0060] Furthermore, the heat dissipation device used in the waist stool of this utility model includes a breathable component with ventilation holes facing the baby on the upper surface of the seat cushion. When the wearer uses the waist stool, because the breathable component with ventilation holes is located at the baby's back, the waist stool can not only dissipate the baby's heat and reduce the amount of sweat, but also minimize discomfort such as dampness, redness, or rashes on the baby's back caused by prolonged use or in hot weather. This helps to soothe the baby and further improves the comfort and satisfaction of both the baby and the wearer.

[0061] In one embodiment, as shown in Figures 5 to 7, the body 22 of the heat dissipation device 2 includes a pipe body 223 with an air inlet 221, and the vent 21 is connected to the pipe body 223; wherein, a portion of the pipe body 223 with the air inlet 221 protrudes from the upper surface 11.

[0062] It is understood that the air inlet 221 is located above the upper surface 11 of the seat cushion 1; the remaining part of the pipe body 223 is located inside the main body 22. In this embodiment, the part of the pipe body 223 with the air inlet 221 protrudes from the upper surface 11 of the seat cushion 1, which makes it easier to detach and install the breathable component 31 and the pipe body 323. For example, when the wearer does not use the breathable component 21 in cool weather, the breathable component 21 can be removed. Also, when the breathable component 21 needs to be cleaned, it can be removed.

[0063] It should be noted that the remaining part of the pipe body 223 is located inside the main body 22. It can be understood that the main body 22 includes the remaining part of the pipe body 223. The specific location of the pipe body 223 in the main body 22 can be set in various ways, which are not limited here.

[0064] The vent 21 and one end of the duct body 223 with the air inlet 221 can be detachably connected together, and the detachable connection can be made by means such as threads and clips.

[0065] Of course, in application scenarios where it is not necessary to disassemble the vent 211, the vent 21 and one end of the pipe body 223 with the air inlet 221 can also be fixedly connected by means such as adhesive bonding.

[0066] In another embodiment, the pipe body 223 at one end of the air inlet 221 does not protrude from the upper surface 11 of the seat cushion 1. Specifically, the air inlet 221 can be flush with the upper surface 11, or the air inlet 221 can be located below the upper surface 11, and the end of the vent 21 near the air inlet 221 is connected to the pipe body 223 below the upper surface 11, thereby connecting the air inlet 221 and the vent hole 211.

[0067] It should be noted that setting the air inlet 221 flush with the upper surface 11 or below the lower surface 11 not only facilitates the wearer's disassembly and assembly, but also solves the technical problem that when the ventilation component 211 is removed, some of the pipes 223 protrude from the upper surface 11, thus affecting the aesthetics of the entire waist stool, and even potentially obstructing the wearer or infant, such obstruction causing discomfort to the wearer's waist or the infant's buttocks or back.

[0068] In one embodiment, the air outlet 222 on the body 22 is located on the lower end face of the body 22 and exposed to the seat cushion 1. As shown in FIG3, in this embodiment, the air outlet 222 is set as the filling body 12 exposed to the seat cushion 1, which serves to exhaust the hot air from the air outlet 222 to the external environment.

[0069] Specifically, when the heat dissipation component 23 in the heat dissipation device 2 is turned on, a negative pressure is generated in the main body 22 and the pipe body 223, so that the heat generated by the baby enters through the vent 211 of the vent 21 and is transferred to the external environment through the air inlet 221, the pipe body 223 and the air outlet 222 in sequence.

[0070] It should be noted that the waist stool may also have an exposed switch that can be turned on or off by the wearer to allow the heat dissipation component 23 to be turned on or off; that is, the switch is connected to the heat dissipation component 23. The main body 22 contains a power supply connected to the switch and the heat dissipation component 23, and may further contain a circuit board connected to the switch, the power supply, and the heat dissipation component 23. Optionally, the switch may also be located on the main body 22.

[0071] In one embodiment, as shown in FIG4, the seat cushion 1 has a first support surface 13 supporting the waist and abdomen of the human body, and the body 22 of the heat dissipation device 2 is disposed between the rear side 121 of the filling body 12 and the first support surface 13.

[0072] Optionally, one side of the body 22 of the heat dissipation device 2 is fitted to the rear side 121 of the filler 12; or, one side of the body 22 of the heat dissipation device 2 is separated from the rear side 121 of the filler 12 by a gap, which is not limited here.

[0073] Optionally, the other side of the body 22 of the heat dissipation device 2 is fitted to the first support surface 13, such as being detachably assembled together; or, the other side of the body 22 of the heat dissipation device 2 is separated from the first support surface 13 by a gap.

[0074] In other words, there are many ways in which the body 22 of the heat dissipation device 2 is located between the rear side 121 of the filler 12 and the first support surface 13, and no restrictions are imposed here.

[0075] In another embodiment, as shown in FIG6, the support surface supporting the waist and abdomen of the human body can also be set on the body 22, that is, the body 22 of the heat dissipation device 2 is provided with a second support surface 224 supporting the human body, that is, the second support surface 224 is the side of the body 22 near the waist and abdomen of the human body.

[0076] Optionally, the second support surface 224 is connected to the upper surface 11. Specifically, the second support surface 224 can be integrated with the body 22. In this case, if the second support surface 224 is assembled with the upper surface 11 of the seat cushion 1, the body 22 and the internal components of the body 22 will also be assembled together.

[0077] In one embodiment, vent holes can also be provided on the upper surface 11 of the seat cushion 1, and vent holes can also be provided on the support surface that supports the human body, so as to discharge the heat inside the seat cushion to the outside, thereby dissipating heat from the seat cushion and preventing problems such as the seat cushion getting too hot.

[0078] In one embodiment, the breathable element 21 may be a textile material having the breathable holes 211.

[0079] Specifically, the breathable element 311 can be any of the following: mesh fabric, non-woven fabric, knitted fabric, and woven fabric. Of course, it can also be other textile materials with breathable holes 311, and there are no restrictions on this.

[0080] It should be noted that the breathable component 31 in this embodiment is made of textile material, which, compared to rigid materials such as metal mesh, has the functions of breathability, softness and moisture absorption, further improving the comfort of the wearer and the baby.

[0081] In one embodiment, the heat dissipation component 23 may be at least one of a fan and a heat sink.

[0082] In an alternative embodiment, as shown in Figure 5, the heat dissipation component 23 includes a fan. When heat dissipation is required, the wearer can turn on the fan via a switch button connected to the fan. When the fan is working, a negative pressure is generated within the body, which draws in hot air through the vents. The air then passes through the air inlet, the duct body, and the air outlet in sequence, and is discharged into the external environment, thus achieving the function of circulating heat dissipation.

[0083] In one alternative embodiment, the heat dissipation component 23 includes not only a fan but also a heat sink. When heat dissipation is required, the wearer turns on the fan. When the fan is working, a negative pressure is generated within the body. Air carrying heat enters through the vent and then enters the duct body through the air inlet. The duct (or air passage) within the duct body guides the air to the heat sink and the fan. The heat sink absorbs heat, and the fan drives the airflow, accelerating the airflow from the air outlet to the external environment, thereby achieving the function of circulating heat dissipation.

[0084] In an alternative embodiment, the heat dissipation assembly 23 consists only of a heat sink, and air is discharged to the external environment through the air inlet, the duct body, the heat sink and the air outlet.

[0085] It should be noted that this embodiment adds a heat sink, which is used in conjunction with the fan for heat dissipation. Compared with the method without a heat sink, the heat dissipation time is shortened and the user experience is better.

[0086] In one embodiment, multiple heat dissipation components 23 and multiple air outlets 222 may be provided, such as two or three, without limitation. Providing multiple heat dissipation components 23 can further accelerate heat dissipation.

[0087] In one embodiment, the heat dissipation device 2 of the waist stool is further provided with a diffusion component, which is connected to the heat dissipation component 23. When the heat dissipation component 23 is activated to dissipate heat, the diffusion component can diffuse and conduct the heat generated by the wearer or infant. The negative pressure generated by the heat dissipation component 23 within the body 22 draws in heat through the vent 211 and transfers the heat to the air outlet 222 for discharge. This embodiment, by adding a diffusion component, can diffuse and conduct heat, and when used with the heat dissipation component, the heat dissipation effect is better.

[0088] In summary, the present invention provides a baby carrier comprising a seat cushion, a support strap, and a heat dissipation device. The heat dissipation device includes a heat dissipation component and a ventilated element disposed on the upper surface of the seat cushion supporting the infant. The ventilated element has vents facing the infant, and these vents are connected to an air inlet and an air outlet. By providing a ventilated element with vents facing the infant on the upper surface of the seat cushion, the present invention allows heat from the air to enter through the vents to the air inlet and exit through the air outlet to the external environment during heat dissipation. This not only dissipates heat but also improves the comfort and satisfaction of the wearer and the infant, thereby soothing the infant and preventing discomfort such as dampness, redness, or rashes on the infant's back due to heat.

[0089] 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.
