Description

Technical Field

[0001] The present utility model belongs to the field of smart bed controllers, and in particular, relates to a controller with a good vibration reduction effect and a smart bed.Background

[0002] The existing smart beds use controllers to inflate and deflate to achieve the function of air mattresses. The existing controllers generally comprise air pumps and solenoid valves connected to the air pumps. An air pump generates significant vibration during operation, and the components inside a controller are in surface contact. The generated vibration is prone to resonance among the components that are in surface contact, which in turn generates noise that is not conductive to sleep. As a result, when the controller is in operation, a user with light sleep may be disturbed by the vibration generated by the air pump and thus unable to fall asleep. Therefore, there is a need to modify the existing control to reduce the influence of the vibration on the user and enhance the use experience.Summary

[0003] Aiming at the problem that the existing controllers generate significant vibration which affects the sleep of a user, the present utility model provides a controller with a good vibration reduction effect and a smart bed. By arranging a solenoid valve assembly in a suspended manner and providing a cushioning member at the connection between a suspension and an inner housing, vibration conduction generated by an air pump assembly is reduced, effectively reducing the influence of vibration on a user.

[0004] The technical solution used by the present utility model is as follows: a controller with a good vibration reduction effect, comprising: an air pump assembly for driving gas, thereby generating airflow; an inner housing for accommodating the air pump assembly; a solenoid valve assembly connected to the air pump assembly and located in a space enclosed by the inner housing, the airflow generated by the air pump assembly being drawn out by opening and closing the solenoid valve assembly; and a suspension connected to an upper portion of the inner housing, the air pump assembly being connected to the suspension from bottom to top in a suspended manner, and a gap being formed between the air pump assembly and the inner housing, a cushioning member being provided at the connection between the suspension and the inner housing.

[0005] The air pump assembly is a component that mainly generates vibration. The air pump assembly is connected to the suspension from bottom to top in a suspended manner, and the cushioning member is provided at the connection between the suspension and the inner housing, and therefore, the air pump assembly is not in direct contact with the inner housing, a transmission path for the vibration generated by the air pump assembly to be transmitted to the inner housing through the cushioning member and the suspension is long, the vibration is gradually weakened, and the noise generated is small, effectively reducing the influence of the vibration.

[0006] Further, the cushioning member comprises a cantilever which is a rigid elastic member; two ends of the cantilever are connected to the upper portion of the inner housing; and a middle section of the cantilever is connected to the suspension from bottom to top. The cantilever is a rigid elastic member, which can ensure the supporting strength and reduce the vibration conduction. Since two ends of the cantilever are connected to the upper portion of the inner housing, and the middle section is connected to the suspension, the vibration generated by the air pump assembly connected to the suspension is transmitted upwards to the cantilever, and then to the upper portion of the inner housing. The connections between various components are in point contact, which makes it difficult to generate resonance during vibration transmission. Moreover, the vibration transmission path is long, causing the vibration to be easily weakened.

[0007] Further, the cushioning member further comprises a vibration reduction foot which is a soft elastic member; an upper portion of the vibration reduction foot is provided with an external thread; a nut is embedded on the suspension; the upper portion of the vibration reduction foot is threadedly connected to the nut; and a lower portion of the vibration reduction foot is fixed to the cantilever through a threaded connecting member. The cantilever is used in conjunction with the vibration reduction foot. The vibration reduction foot is a soft elastic member, which can absorb some of the vibration and reduce the vibration transmitted to the inner housing.

[0008] Further, a first vibration reduction rubber is provided at the connection between the air pump assembly and the suspension; and the first vibration reduction rubber comprises a damping portion which can be penetrated on the suspension and a connecting portion which is connected to an outer side of the air pump assembly. Since the first vibration reduction rubber is a soft material and can absorb some of the vibration, the vibration generated by the air pump assembly is weakened by the first vibration reduction rubber before reaching the suspension, effectively reducing the amount and amplitude of vibration transmitted to the suspension.

[0009] Further, the air pump assembly comprises an air pump main body and a box body for accommodating the air pump main body; at least two screws are transversely arranged in the box body; and the air pump main body is connected to the screws through a vibration reduction belt, so that the air pump main body is suspended in the box body. The air pump main body is suspended in the box body, and the vibration generated thereby is only transmitted to the box body through the transversely arranged screws and the vibration reduction belt. The vibration can be partially absorbed by the vibration reduction belt, effectively reducing the amount and amplitude of vibration transmitted to the box body.

[0010] Further, the controller with a good vibration reduction effect further comprises an outer shell, wherein the outer shell is located on an outer side of the inner housing and is connected to the inner housing through a connecting column, so that a gap is formed between the outer shell and the inner housing; and the connecting column is a vibration reduction member. The outer shell encloses the inner housing, providing better protection. Moreover, the connecting column is provided between the inner housing and the outer shell, so that the inner housing is in point contact with the outer shell, and the connecting column is a vibration reduction member, which can reduce vibration conduction by absorbing some of the vibration.

[0011] Further, the solenoid valve assembly is connected to a lower portion of the suspension from bottom to top through a second vibration reduction rubber. This structure allows the solenoid valve assembly to be suspended on the suspension. The solenoid valve assembly also generates vibration during operation, and the second vibration reduction rubber provided can absorb some of the vibration, effectively reducing vibration transmission.

[0012] Further, a main air box is provided between the solenoid valve assembly and the air pump assembly so as to cushion the airflow that passes through the main air box; and the main air box is connected to the suspension. The airflow generated by the air pump assembly first flows into the main air box, and then into the solenoid valve assembly, so that the airflow is initially cushioned at the main air box, which can weaken the vibration generated by the airflow.

[0013] Further, a joint female seat is provided on the inner housing; the solenoid valve assembly is connected to the joint female seat through a secondary cushioning air box which is used for cushioning the airflow that passes through the secondary cushioning air box; and upper and lower sides of the secondary cushioning air box are respectively provided with a secondary circuit board and a main circuit board which are connected through a flat cable. The secondary cushioning air box is located between the solenoid valve assembly and the joint female seat to cushion the airflow flowing out of the solenoid valve assembly, so that the airflow is further cushioned at the secondary cushioning air box, and the vibration generated by the airflow is further weakened.

[0014] As another inventive point, the present application further provides a smart bed, comprising a bedstead, an air mattress, and a controller for controlling the operation of the air mattress, wherein the controller is mounted below the bedstead and is connected to the air mattress through an air pipeline; and the controller is the controller with a good vibration reduction effect above.

[0015] The beneficial effect of the present utility model is as follows: the present application provides a controller with a good vibration reduction effect and a smart bed, in which the air pump assembly is connected to the suspension from bottom to top in a suspended manner, and the cushioning member is provided at the connection between the suspension and the inner housing. A transmission path for the vibration generated by the air pump assembly to be transmitted to the inner housing through the cushioning member and the suspension is long, the vibration is gradually weakened, and the noise generated is small, effectively reducing the influence of the vibration.Description of Drawings

The cantilever 4 is a rigid elastic member, which can ensure the supporting strength and reduce the vibration conduction. Since two ends of the cantilever 4 are connected to the upper portion of the inner housing 2, and the middle section is connected to the suspension 3, the vibration generated by the air pump assembly 1 connected to the suspension 3 is transmitted upwards to the cantilever 4, and then to the upper portion of the inner housing 2. The connections between various components are in point contact, which makes it difficult to generate resonance during vibration transmission. Moreover, the vibration transmission path is long, causing the vibration to be easily weakened.

The cantilever 4 is a rigid elastic member, which can ensure the supporting strength and reduce the vibration conduction. Since two ends of the cantilever 4 are connected to the upper portion of the inner housing 2, and the middle section is connected to the suspension 3, the vibration generated by the air pump assembly 1 connected to the suspension 3 is transmitted upwards to the cantilever 4, and then to the upper portion of the inner housing 2. The connections between various components are in point contact, which makes it difficult to generate resonance during vibration transmission. Moreover, the vibration transmission path is long, causing the vibration to be easily weakened.

Since the first vibration reduction rubber 1-5 is a soft material and can absorb some of the vibration, the vibration generated by the air pump assembly 1 is weakened by the first vibration reduction rubber 1-5 before reaching the suspension 3, effectively reducing the amount and amplitude of vibration transmitted to the suspension. The first vibration reduction rubber is clamped, bonded, or sleeved on the outer side of the air pump assembly. The damping portion is clamped on the suspension 3 to providing better positioning.

The air pump main body 1-1 is suspended in the box body 1-2, and the vibration generated thereby is only transmitted to the box body 1-2 through the transversely arranged screws 1-4 and the vibration reduction belt 1-2. The vibration can be partially absorbed by the vibration reduction belt 1-3, effectively reducing the amount and amplitude of vibration transmitted to the box body 1-2.

[0024] The controller with a good vibration reduction effect further comprises an outer shell 6, wherein the outer shell 6 is located on an outer side of the inner housing 2 and is connected to the inner housing 2 through a connecting column 6-1, so that a gap is formed between the outer shell 6 and the inner housing 2; and the connecting column 6-1 is a vibration reduction member.

[0029] The air pump assembly 1 is a component that mainly generates vibration. The air pump assembly 1 is connected to the suspension 3 from bottom to top in a suspended manner, and the cushioning member is provided at the connection between the suspension 3 and the inner housing 2, and therefore, the air pump assembly 1 is not in direct contact with the inner housing 2, a transmission path for the vibration generated by the air pump assembly 1 to be transmitted to the inner housing 2 through the cushioning member and the suspension 3 is long, the vibration is gradually weakened, and the noise generated is small, effectively reducing the influence of the vibration.

[0030] In this embodiment, the vibration generated by the air pump assembly 1 achieves a first-level cushioning effect through the cantilever 4. The vibration reduction foot 5 is provided to absorb some of the vibration, achieving a second-level cushioning effect. The air pump assembly 1 is suspended on the suspension 3 through the first vibration reduction rubber 1-5, achieving a third-level cushioning effect. The air pump assembly 1 is connected to the screws through the vibration reduction belt 1-3, achieving a fourth-level cushioning effect. In this way, the influence of the vibration on the user is gradually weakened, and the vibration reduction effect is good.Embodiment 2
