Description

Technical Field

[0001] The utility model belongs to the field of intelligent bed accessories, and particularly relates to a controller and an intelligent bed used on an air mattress. Background Art

[0002] Existing intelligent beds use a controller to inflate and deflate to realize the functions of an air mattress. The existing controller usually includes an electromagnetic valve connected to an air pump. When the electromagnetic valve works, it will generate large vibrations, and the contact surfaces of various components in the controller are large, and there are many vibration transmission paths. The generated vibrations are prone to resonance at large contact surfaces, and the resonance will cause noise that is not conducive to sleep. When this existing controller works, users with light sleep will be disturbed by the vibrations generated by the air pump and thus cannot fall asleep. Therefore, it is necessary to improve the existing controller to reduce the impact of vibrations on users and enhance the user experience. Summary of the Utility Model

[0003] Aiming at the problems of the existing technology, the utility model provides a controller and an intelligent bed used on an air mattress, which relieve the impact brought by vibrations by suspending the electromagnetic valve assembly and arranging a shock-absorbing belt on the electromagnetic valve assembly.

[0004] The technical solution adopted by the utility model is as follows: A controller used on an air mattress includes:

[0005] An inner housing;

[0006] A suspension, connected to the upper part of the inner housing, playing a supporting role;

[0007] An air pump assembly, used to generate air flow, arranged in the inner housing;

[0008] An electromagnetic valve assembly, located in the inner housing, and arranged on the suspension from bottom to top. The electromagnetic valve assembly is connected to the air pump assembly, and the on-off of the air flow is controlled by opening and closing the electromagnetic valve assembly;

[0009] The electromagnetic valve assembly is directly or indirectly connected to the suspension through a shock-absorbing belt, so that the electromagnetic valve assembly is suspended inside the inner housing.

[0010] The electromagnetic valve assembly that generates vibrations is suspended on the suspension, and the two are only connected through a shock-absorbing belt, effectively reducing the contact area and the vibration transmission path, thereby reducing noise. Moreover, the shock-absorbing belt can absorb part of the vibrations, further reducing the vibrations and effectively relieving the impact brought by the vibrations.

[0011] Further, a protective frame is provided outside the solenoid valve assembly. The protective frame surrounds the solenoid valve assembly. The shock-absorbing belt includes a first connection end threaded through the suspension and a second connection end threaded through the protective frame. Damping portions are provided at both the first connection end and the second connection end. The protective frame plays a protective role to prevent the solenoid valve assembly from being scratched by sharp objects and losing its function. The shock-absorbing belt has a certain toughness and elasticity, and damping portions are provided at both ends thereof. The two damping portions can be respectively clamped on the suspension and the protective frame, facilitating the installation of the protective frame.

[0012] Further, at least two shock-absorbing belts are provided and symmetrically arranged on both sides of the protective frame. To ensure structural stability, a plurality of shock-absorbing belts are usually selected. In addition, the symmetrical structure can also reduce the generation of irregular noises and further alleviate the discomfort caused by the noises.

[0013] Further, a main air box is provided between the air pump assembly and the solenoid valve assembly. The protective frame has a connection end, and the connection end is connected to the main air box to support the main air box. When the air flow generated by the air pump assembly flows towards the solenoid valve assembly through the main air box, the flow rate is delayed by the main air box, effectively reducing the noise impact caused by wind noise.

[0014] Further, the suspension is connected to the inner housing through a cantilever. The middle section of the cantilever is connected to the suspension upwards, and both ends of the cantilever are connected to the upper part of the inner housing downwards. The cantilever is a sheet spring steel. The suspension and the inner housing are only connected by the cantilever, with a small contact area and few vibration transmission paths. Moreover, the cantilever is a sheet-shaped spring steel piece, which has good toughness, can provide sufficient support, and also has a certain elasticity to absorb part of the vibration and reduce vibration transmission.

[0015] Further, a plurality of shock-absorbing feet are provided at the connection between the suspension and the cantilever. The shock-absorbing feet are rubber parts. The rubber shock-absorbing feet can absorb part of the vibration, and the vibration is weakened when transmitted from the suspension to the cantilever, thereby reducing the impact of the vibration.

[0016] Further, an outer housing is provided outside the inner housing. The inner housing is connected to the outer housing through a connecting column, and the connecting column is a rubber part. The outer housing plays a good protective role for the inner housing. The outer housing and the inner housing are only connected by the connecting column, with a small contact area and a single vibration transmission path. Moreover, the connecting column is an elastic rubber part, effectively reducing the amount of vibration transmitted from the inner housing to the outer housing.

[0017] Furthermore, there are two sets of the air pump assemblies, which are respectively arranged on both sides of the solenoid valve assembly. The air pump assembly includes an air pump main body and a housing for accommodating the air pump main body. A shock-absorbing strip is connected to the outside of the housing. The middle section of the shock-absorbing strip is connected to the housing, and both ends of the shock-absorbing strip are connected upward to the suspension. The symmetrically arranged structure effectively reduces the generation of irregular vibrations. The shock-absorbing strip is snap-connected, inserted, or sleeved on the outside of the housing, which can not only reduce the vibration transmission but also ensure the structural stability.

[0018] Furthermore, a pair of buffer air boxes are provided on the suspension. The input end of the auxiliary buffer air box is connected to the output end of the solenoid valve assembly, and the output end of the auxiliary buffer air box is connected to a female connector seat arranged on the inner housing. The auxiliary buffer air box is connected to the female connector seat, and the air flow is further buffered before output, further reducing the wind noise generated by the air flow.

[0019] An intelligent bed includes a bed frame, an air mattress, and a controller connected to the air mattress. The controller is used to control the inflation and deflation of the air mattress, and the controller uses the controller used on the above-mentioned air mattress.

[0020] The beneficial effects of the present utility model are as follows: This application is a controller used on an air mattress and an intelligent bed. The solenoid valve assembly that generates vibrations is suspended on the suspension, and the two are only connected by a shock-absorbing belt, effectively reducing the contact area and the vibration transmission path, thereby reducing noise. Moreover, the shock-absorbing belt can absorb part of the vibrations, further reducing the vibrations and effectively alleviating the influence brought by the vibrations. Description of the Drawings
