Description

Technical Field

[0001] This utility model relates to heat dissipation technology, and more particularly to a heat dissipation device and bedding. Background Technology

[0002] People with cervical spondylosis or those seeking cervical spine health care can use smart pillows with built-in traction airbags to provide traction and massage to relieve discomfort or promote cervical spine health. These smart pillows are divided into two categories based on their power supply: external power supply and built-in rechargeable battery power supply. For smart pillows powered by built-in rechargeable batteries, battery heat dissipation is a technical problem that needs to be solved. Current technology generally uses a cooling fan inside the pillow for heat dissipation. However, using a cooling fan not only generates noise but also complicates the product structure, thus reducing product reliability. Utility Model Content

[0003] This utility model provides a heat dissipation device and bedding. The technical problem to be solved is how to dissipate heat from the battery built into the bedding.

[0004] This utility model is achieved through the following technical solution:

[0005] A heat dissipation device includes an air pump, a first air valve, a second air valve, and an inflation / deflation pipeline. The air pump, the first air valve, and the second air valve are connected in pairs through the inflation / deflation pipeline. The first air valve is used to connect to an airbag that needs to be inflated or deflated. When the airbag is depressurized, the airflow released through the first air valve enters the inflation / deflation pipeline and then flows out from the second air valve. When the first air valve is closed, the airflow drawn in by the air pump enters the inflation / deflation pipeline and then flows out from the second air valve. The second air valve is configured to allow the airflow to flow through it and then through a heat-generating component to remove the heat generated by the heat-generating component.

[0006] Furthermore, the second air valve is configured such that its airflow direction is toward the heating element.

[0007] Furthermore, the heat dissipation device also includes a housing, the interior of which forms a receiving cavity. The air pump, the air charging / discharging pipeline, the first air valve, the second air valve, and the heating element are all disposed within the receiving cavity. The receiving cavity has an air inlet and an air outlet. The air pump draws in airflow from the air inlet, and the airflow flows out from the second air valve and then out from the air outlet. The heating element is located on the airflow path from the second air valve to the air outlet.

[0008] Furthermore, the air pump, the air filling and discharging pipeline, the second air valve, and the heating element are arranged sequentially along the first direction, with the air pump located at the air inlet and the heating element located at the air outlet.

[0009] Furthermore, the heat dissipation device also includes a temperature sensor and a controller. The temperature sensor detects the temperature of the heat-generating component. When the temperature of the heat-generating component exceeds the standard, the controller closes the first air valve and sends a command to the air pump to draw in airflow. After receiving the command, the air pump draws in airflow.

[0010] Furthermore, the heating element is a battery.

[0011] A bedding set including the heat dissipation device as described above.

[0012] Compared with the prior art, the heat dissipation device provided by this utility model includes an air pump, a first air valve, a second air valve, and an inflation / deflation pipeline. The air pump, the first air valve, and the second air valve are connected in pairs through the inflation / deflation pipeline. The first air valve is used to connect the airbag that needs to be inflated or deflated. When the airbag is depressurized or when the first air valve is closed, the air pump can generate airflow, which enters the inflation / deflation pipeline and flows out through the second air valve, thereby dissipating heat from the heat-generating components. This eliminates the need for a cooling fan, thus avoiding fan noise. At the same time, since there is no need to set up an additional dedicated cooling fan, the product structure is not complicated, thereby improving product reliability. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the heat dissipation device provided by this utility model. Detailed Implementation

[0014] This utility model discloses a heat dissipation device capable of cooling a heat-generating component 5. The heat-generating component 5 can be a battery or a circuit board, etc., and these components have temperature requirements. Figure 1As shown, the heat dissipation device includes an air pump 1, a first air valve 2, a second air valve 3, and an inflation / deflation pipeline 4. The air pump 1, the first air valve 2, and the second air valve 3 are connected in pairs via the inflation / deflation pipeline 4. The first air valve 2 connects to the airbag that needs to be inflated / deflated. When the airbag needs to be inflated, the second air valve 3 is closed, and the air pump 1 inflates the airbag through the inflation / deflation pipeline 4. When the airbag is depressurized, the airflow released through the first air valve 2 enters the inflation / deflation pipeline 4 and then flows out through the second air valve 3. When the first air valve 2 is closed, the airflow drawn in by the air pump 1 enters the inflation / deflation pipeline 4 and then flows out through the second air valve 3. The second air valve 3 is configured to allow the airflow to flow through it and then through the heating element 5 to carry away the heat generated by the heating element 5. In this way, when the airbag is depressurized and when air is drawn in by the air pump 1 with the first air valve 2 closed, airflow can be generated and enter the inflation / deflation pipeline 4 and flow out through the second air valve 3, thereby dissipating heat from the heat-generating component 5. This eliminates the need for a cooling fan, thus preventing fan noise. At the same time, since there is no need to set up an additional dedicated cooling fan, the product structure is not complicated, thereby improving product reliability.

[0015] The second air valve 3 is configured such that airflow flows through it and then passes through the heating element 5 in two ways, including but not limited to the following:

[0016] Method 1: Configure the second air valve 3 so that its airflow direction is towards the heating element 5. For example... Figure 1 As shown, the outlet 6 of the second air valve 3 is set to face the heating element 5, so that the airflow direction when it flows out of the second air valve 3 is towards the heating element 5, so that the airflow flows through the heating element 5 after it flows out of the second air valve 3.

[0017] Method 2: The heat dissipation device also includes a housing 7, inside which a receiving cavity 8 is formed. The air pump 1, the charging / discharging pipeline 4, the first air valve 2, the second air valve 3, and the heating element 5 are all disposed within the receiving cavity 8. The receiving cavity 8 has an air inlet 9 and an air outlet 10. The air pump 1 draws in air through the air inlet 9, and the air flows out through the second air valve 3 and then out through the air outlet 10. The heating element 5 is located on the airflow path from the second air valve 3 to the air outlet 10. The receiving cavity 8 formed by the housing 7 ensures that the airflow entering the receiving cavity 8 through the air inlet 9 can only flow out through the air outlet 6, thus limiting the airflow path to a certain extent. Compared with Method 1, this method can more effectively control the airflow path, thereby achieving a better heat dissipation effect on the heating element 5.

[0018] It should be noted that Method 1 and Method 2 can coexist. In practice, either Method 1 or Method 2 can be used, or both can be used simultaneously.

[0019] An air pump 1, an air filling / discharging pipeline 4, a second air valve 3, and a heating element 5 can be arranged sequentially along a first direction, with the air pump 1 located at the air inlet 9 and the heating element 5 located at the air outlet 10. The advantage of this arrangement is that the airflow travels in one direction throughout the entire process from entering the receiving cavity 8 to exiting the receiving cavity 8, which is more conducive to airflow guidance and also more conducive to the layout of various functional components within the receiving cavity 8.

[0020] The heat dissipation device may also include a temperature sensor and a controller. The temperature sensor detects the temperature of the heat-generating component 5, and the controller closes the first air valve 2 and sends a command to the air pump 1 to draw in air when the temperature of the heat-generating component 5 exceeds the limit. Upon receiving the command, the air pump 1 draws in air. By introducing a temperature sensor and a controller, automatic heat dissipation can be achieved when the temperature of the heat-generating component 5 exceeds the limit, thus improving the product's intelligence level.

[0021] Based on the aforementioned heat dissipation device, this utility model also provides a bedding set, which includes the heat dissipation device described above. The bedding set can be a pillow or a mattress, etc.
