[0002] The invention relates to a fan assembly and a baby mattress comprising the same. Background Art

[0003] When babies sleep at night, their bedding and body temperatures differ from those of adults. To ensure a comfortable sleeping environment for babies, it's necessary to adjust the bed temperature by turning on the air conditioner or adding more blankets. However, this approach is cumbersome, ineffective, and can also lead to problems like poor air circulation for the baby. To address this issue, heated mattresses have been introduced. A heating fan blows hot air into the mattress, raising and maintaining a constant temperature, creating a more comfortable sleeping environment for the baby.

[0004] However, the hot air blower in the prior art often has an overly high temperature at the air inlet, causing the mattress and circuit board connected to the air inlet to be exposed to a high temperature environment for a long time and damaged. After the heated mattress has been used for a period of time, problems such as local overheating and failure of control effect will occur, which greatly reduces the service life of the heated mattress.

[0005] Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects in the prior art of the heated mattress in that the temperature at the air inlet is too high, resulting in local overheating of the mattress and a shortened service life of the circuit board and the fan, and to provide a fan assembly and a baby mattress including the same.

[0007] The present invention solves the above technical problems through the following technical solutions:

[0008] A fan assembly is applied to a baby mattress, the fan assembly comprising: a mounting shell, a fan and an air guide, the fan being arranged inside the mounting shell; the air guide being connected to the air outlet of the fan, the air guide comprising a hot air channel, a first natural wind channel and a second natural wind channel, the hot air channel extending toward the outside of the mounting shell and connected to the mattress body, the outlet of the first natural wind channel facing the connection between the hot air channel and the baby mattress, and the outlet of the second natural wind channel facing the interior of the mounting shell.

[0009] In this solution, the above-mentioned structural form is adopted, so that the air blown out from the fan is heated by the hot air channel and then flows into the mattress body, thereby heating the baby mattress; at the same time, the air flowing through the first natural air channel blows toward the connection between the hot air channel and the baby mattress, thereby cooling the connection, effectively avoiding local overheating of the mattress body and ensuring the safety and comfort of the baby mattress; in addition, the air flowing through the second natural air channel blows toward the interior of the mounting shell, thereby cooling the interior of the mounting shell, effectively avoiding damage to equipment such as the fan and circuit boards due to temperature rise in the mounting shell, thereby extending the service life of the fan assembly; the structure of the fan assembly is simple and compact, and a single fan can be used to supply hot air to the baby mattress and cool the connection position and the mounting shell, so that the fan is fully utilized, effectively saving energy, and facilitating installation, control and maintenance.

[0036] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0037] As shown in Figures 1 to 8, this embodiment discloses a fan assembly 1, which is applied to a baby mattress. The fan assembly 1 includes: a mounting shell 11, a fan 12 and an air guide 13. The fan 12 is arranged inside the mounting shell 11; the air guide 13 is connected to the air outlet of the fan 12, and the air guide 13 includes a hot air channel 131, a first natural wind channel 132 and a second natural wind channel 133. The hot air channel 131 extends to the outside of the mounting shell 11 and is connected to the mattress body 2. The outlet of the first natural wind channel 132 is toward the connection between the hot air channel 131 and the baby mattress, and the outlet of the second natural wind channel 133 is toward the inside of the mounting shell 11.

[0038] As shown in Figures 1 to 5, a fan 12 is provided within the mounting shell 11. The air outlet of the fan 12 is connected to an air guide 13. The air guide 13 is provided with three layers, namely a hot air channel 131 in the middle layer, and a first natural air channel 132 and a second natural air channel 133 on both sides. The other end of the hot air channel 131 is connected to the mattress body 2 via a connector 14. The outlet of the first natural air channel 132 faces the connection between the hot air channel 131 and the connector 14, while the outlet of the second natural air channel 133 faces the interior of the mounting shell 11. Specifically referring to Figure 5, A in the figure represents the flow path of the wind in the hot air channel 131, B represents the flow path of the wind in the first natural air channel 132, and C represents the flow path of the wind in the second natural air channel 133. The air blown out from the fan 12 is heated by the hot air channel 131 and then flows into the mattress body 2, thereby heating the baby mattress; at the same time, the air flowing through the first natural air channel 132 blows toward the connection between the hot air channel 131 and the baby mattress, thereby cooling the connection, effectively avoiding local overheating of the mattress body 2 and ensuring the safety and comfort of the baby mattress; in addition, the air flowing through the second natural air channel 133 blows toward the interior of the mounting shell 11, thereby cooling the interior of the mounting shell 11, effectively avoiding damage to equipment such as the fan 12 and circuit boards due to temperature rise in the mounting shell 11, thereby extending the service life of the fan assembly 1; the fan assembly 1 has a simple and compact structure, and can supply hot air to the baby mattress and cool the connection position and the mounting shell 11 through a single fan 12, so that the fan 12 is fully utilized, effectively saving energy, and facilitating installation, control and maintenance.

[0039] In a preferred embodiment, as shown in Figures 1 and 4 , the fan 12 is vertically arranged, with the air outlet of the fan 12 facing vertically downward. As shown in Figures 6 and 7 , a side panel 22 is provided on the side of the mattress body 2 , and the mounting shell 11 is detachably mounted on the side surface of the side panel 22 .

[0040] As can be seen from Figures 1 and 7, the fan assembly 1 is generally in the shape of a vertical box, and the fan 12, controller 16, and other components therein are also arranged vertically, so that the fan assembly 1 can be embedded in the vertical enclosure 22, with its side edges flush with the side surfaces of the enclosure 22, thereby ensuring that the structure of the baby mattress is compact and aesthetically pleasing, and there are no protruding structures, effectively preventing the baby from colliding with the mattress during use, thereby ensuring the safety and comfort of the baby mattress. In other embodiments, depending on the specific structure of the baby mattress, the fan assembly 1 can also be set horizontally or tilted to match the structure of the mattress body 2. Therefore, the specific structure of the fan assembly 1 and its internal components such as the fan 12 and controller 16 are not limited to the scope disclosed in this embodiment.

[0041] In a preferred embodiment, as shown in FIG. 2 and FIG. 3 , the first natural wind channel 132 and the second natural wind channel 133 are respectively provided on both sides of the hot wind channel 131 , and the hot wind channel 131 is bent to form an arc shape.

[0042] As shown in Figures 4 and 5, the hot air channel 131 is bent toward the mattress body 2, the first natural air channel 132 is located on the side of the hot air channel 131 close to the mattress body 2, and the second natural air channel 133 is located on the side of the hot air channel 131 away from the mattress body 2.

[0043] As can be seen from FIG5 , after the hot air channel 131 is bent, the wind generated by the fan 12 is introduced into the connector 14 along path A, and then introduced into the mattress body 2, thereby ensuring that the fan assembly 1 provides a heat source for the mattress body 2; at the same time, after the hot air channel 131 is bent, the outlet of the first natural wind channel 132 is exactly opposite the bending part of the hot air channel 131, so that the wind blown from the fan 12 into the first natural wind channel 132 effectively cools the connection between the hot air channel 131, the connector 14 and the mattress body 2 along path B; in addition, as shown in FIG1 , FIG2 and FIG5 , After the hot air channel 131 is bent, since the second natural wind channel 133 is arranged on the side of the hot air channel 131 away from the mattress body 2, there is no obstruction at the outlet of the second natural wind channel 133 and it directly faces the interior of the mounting shell 11, so that the wind flowing into the second natural wind channel 133 from the fan 12 is blown into the mounting shell 11 along the C path, and the interior of the mounting shell 11 is cooled, thereby ensuring the safety of the internal components of the fan assembly 1 and preventing damage due to overheating, effectively improving the service life of the fan assembly 1 and ensuring its stability and safety during operation.

[0044] In a preferred embodiment, as shown in Figures 2 and 3 , fan assembly 1 includes a heating element 134 disposed within hollow hot air passage 131. This allows airflow from fan 12 to flow through hot air passage 131, where it is heated by heating element 134 and then into mattress body 2. This simple structure does not affect the normal operation of first and second natural air passages 132, 133, thereby ensuring the safety of fan assembly 1.

[0045] In a preferred embodiment, as shown in Figures 1, 5, and 8, the fan assembly 1 includes a connector 14, one end of which is connected to the air guide 13 and the other end is connected to the mattress body 2.

The connector 14 has multiple hollow branch joints 141, each of which is connected to the multiple air supply pipes 25. Each air supply pipe 25 is provided with multiple air supply holes 251, which penetrate the heating pad 21. This allows the hot air flowing out of the branch joints 141 to flow evenly into the air supply pipes 25 and out through the air supply holes 251, thereby achieving the effect of heating the mattress and regulating the sleeping environment temperature. Furthermore, the hot air flow generated by the fan assembly 1 is introduced into various parts of the mattress body 2 through the connector 14 and the branch connector 141, thereby heating the mattress body 2 as a whole, making the temperature of each position of the mattress body 2 uniform and constant, thereby ensuring the comfort and safety of the baby mattress.

[0046] In a preferred embodiment, the mattress body 2 is formed by laminating an upper heating pad 21 and a lower sealing pad. The heating pad 21 and the enclosure 22 are made of a one-piece polyurethane foam material, and the lower sealing pad is made of a sponge hot-pressed. By selecting the polyurethane foam material, the heating pad 21 and the enclosure 22 can be made into an integral part, and the polyurethane foam material has good elasticity and is light in weight, making the overall weight of the mattress body 2 light and providing a good sleeping experience. In addition, the polyurethane foam material has good airtightness, so that the air supply duct 25 formed after the polyurethane foam material and the sponge material are laminated can effectively transmit wind.

[0047] In other embodiments, the materials of the various components of the mattress body 2 can be adjusted accordingly based on actual production requirements, cost requirements, etc. For example, the heating pad 21 and the surrounding plate 22 can be made of hot-pressed sponge, and the lower sealing pad can be made of a one-piece polyurethane foam material; or the entire mattress body 2 can be made of a one-piece polyurethane foam material. Therefore, the specific material of the mattress body 2 is not limited to the scope disclosed in this embodiment.

The mounting shell 11 is disposed within the outer shell 152, and the multiple mounting portions 151 are respectively disposed on the outer surface of the outer shell 152. The connecting shell 15 is connected to the mattress body 2 via the multiple mounting portions 151. The fan assembly 1 is connected to the surrounding panel 22 of the mattress body 2 via the multiple mounting portions 151 on the connecting shell 15. The mounting shell 11 is detachably connected to the outer shell 152 of the connecting shell 15, thereby facilitating the removal of the various components of the fan assembly 1 for maintenance and replacement, effectively improving the convenience of the baby mattress.

[0049] In a preferred embodiment, as shown in Figures 1 and 6 , the fan assembly 1 includes a cover plate 17, a controller 16, a temperature detector 24, and a humidity detector 23. The controller 16 is disposed within the mounting housing 11, and the output of the controller 16 is electrically connected to the fan 12. The temperature detector 24 and the humidity detector 23 are both disposed within the mattress body 2 and are used to detect the temperature and humidity of the mattress body 2. The temperature detector 24 and the humidity detector 23 are electrically connected to the input of the controller 16. The cover plate 17 covers the surface of the fan assembly 1 and is provided with the air inlet slot for the fan 12 and a start button.

[0050] As shown in FIG6 , the temperature and humidity of the mattress body 2 are detected by the temperature detector 24 and the humidity detector 23, and the detection signal is sent to the controller 16. The controller 16 controls the switch of the fan 12 and issues an alarm signal according to the detection signal, thereby ensuring that the temperature of the baby mattress is constant when the baby is sleeping, ensuring the comfort and safety of the baby when sleeping, and also reminding the guardian by issuing an alarm signal when the baby wets the bed, further improving the safety and user experience of the baby mattress.
