[0005] Preferably, the switch element is located on the second silencer cavity.

[0006] Preferably, the control box further comprises a bottom shell, and the second silencer cavity is located between the bottom shell and the switch element.

[0007] Preferably, the first silencer cavity is connected to the air pump module via a one-way air valve.

[0008] Preferably, there are two silencer modules, and the first silencer cavities of the two silencer modules are arranged side by side.

[0009] Preferably, the first air pipe is located between the first silencing cavity and the second silencing cavity.

[0010] Preferably, the second silencing cavity is provided with an air outlet.

[0011] Preferably, the silencer module further comprises a connecting portion connected to the first silencer cavity, and the connecting portion is used for installing an air pressure sensor.

[0012] Preferably, the switch element is a solenoid valve.

[0013] A bedding comprises the above control box.

[0014] Compared with the prior art, the switch element provided by the utility model is closed when the first air pipe is inflating the external device and is opened when the first air pipe is deflated, so that the first silencer cavity is connected with the second silencer cavity. In this way, the gas flows to more silencer cavities during deflation, thereby effectively reducing the airflow noise.

[0024] In order to make the purpose, technical solution and beneficial technical effect of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described in this specification are only for explaining the utility model, and are not intended to limit the utility model.

[0025] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
