Description

Technical Field

[0001] The utility model relates to a control box and bedding using the control box, in particular to a multiple vibration-damping control box and a pillow using the same. Background Art

[0002] A pillow that automatically adjusts its height and / or has a massage function includes a pillow body, an airbag disposed within the pillow body, and a control box that controls the inflation or deflation of the airbag. The control box includes the control box body, a control panel disposed within the control box body, an inflation and deflation assembly connected to the control panel (which includes an air pump, a solenoid valve connected to the air pump control, control lines connecting the solenoid valve and the air pump, and several air pipes connected to the air pump, etc.; when in operation, the air pump, solenoid valve, and air pipes all generate vibration and noise). The inflation and deflation assembly is connected to the airbag within the pillow body via the air pipes. Because the inflation and deflation assembly vibrates during inflation or deflation, the vibration generates a relatively loud noise. However, pillows are used in relatively quiet resting or sleeping environments, and vibration and noise will affect the user's rest or sleep quality. In severe cases, it can easily prevent the user from resting or sleeping, and the massage or height adjustment function may be disabled, which not only fails to achieve the height adjustment and massage functions but also results in a certain amount of waste. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and to provide a multiple vibration-damping control box and a pillow using the same. A second shell is added inside the first shell. At the same time, the air pump is suspended on the top wall of the second shell so that the vibration of the air pump is absorbed by the elastic suspension member that suspends the air pump, thereby greatly reducing the vibration of the air pump during operation and transmitting it to the second shell and the first shell in turn, thereby reducing the vibration and noise generated by the inflation and deflation components during operation and transmitting them from the inside of the shell to the outside, ultimately achieving the purpose of vibration reduction and noise reduction, which is conducive to keeping the pillow use environment quiet, and further conducive to improving the user's rest and sleep quality.

[0004] The above-mentioned technical objectives of the present invention are primarily achieved through the following technical solution: a multi-vibration damping control box comprising a housing, an air pump disposed within the housing, a circuit board for controlling the operation of the air pump, and an air path mechanism connected to the air pump, characterized in that the housing comprises a first housing, a second housing disposed within the first housing and cooperating with the first housing for noise reduction, the air pump and the air path mechanism being disposed within the inner cavity of the second housing, and the air pump being suspended from the top wall of the second housing. This technical solution differs from the prior art in that a second housing is added within the first housing, and the air pump is suspended from the top wall of the second housing. The effect is: since the vibration of the air pump during operation is the main vibration source, absorbing and isolating the vibration of the air pump is an effective vibration reduction and noise reduction solution. Specifically, the vibration of the air pump is absorbed by the elastic suspension parts that suspend the air pump, which greatly reduces the vibration of the air pump during operation and is transmitted to the second shell and the first shell in turn, thereby reducing the impact of the air pump vibration on the normal and effective use of the pillow, and is beneficial to maintaining and improving the user's normal rest and sleep quality; at the same time, the second shell isolates the vibration transmitted to the second shell by the inflation and deflation component, so that the vibration of the inflation and deflation component can rarely be transmitted to the first shell, thereby achieving the purpose of reducing the vibration generated when the inflation and deflation component is working, and thus also reducing the noise generated by the vibration, which is ultimately beneficial to keeping the pillow use environment quiet, and thus beneficial to improving the user's rest and sleep quality.

[0005] As a further improvement and supplement to the above technical solution, the present invention employs the following technical measures: a fixed sleeve is mounted on the air pump, and an elastic suspension member is provided on the fixed sleeve, through which the air pump is suspended from the top wall of the second housing. The provision of the elastic suspension member effectively absorbs vibrations generated by the air pump during operation, reducing the transmission of vibrations generated by the air pump to the second housing, and ultimately effectively reducing vibrations generated by the control box during operation.

[0006] Preferably, there are at least two fixing sleeves, one mounted on each end of the air pump. The fixing sleeve is provided with a first connecting ear, and the elastic suspension member is provided with at least two clamping grooves. The elastic suspension member extends through a first connecting hole on the first connecting ear and a second connecting hole on the second housing. The wall of the first connecting hole engages with one clamping groove, and the wall of the second connecting hole engages with the other clamping groove. Having at least two fixing sleeves facilitates stable suspension of the air pump and further reduces vibrations generated during operation. The provision of the first connecting ear and the clamping groove facilitates a stable and reliable connection between the fixing sleeve and the elastic suspension member.

[0007] Preferably, the elastic suspension member is provided with a plurality of spaced convex rings, and the space between two adjacent convex rings is the clamping groove. The cooperation between the convex rings and the clamping groove is conducive to forming a stable and reliable connection between the elastic suspension member and the first connecting ear.

[0008] Preferably, the two adjacent protruding rings are respectively a flat plate protruding ring and a guide protruding ring. The outer end surface of the guide protruding ring is an outer convex guide surface, and the inner end surface is a flat surface. The guide protruding ring is used to guide the elastic suspension member through the corresponding connecting hole so that the two protruding rings are respectively clamped on the corresponding first connecting ear and the second housing. The flat plate protruding ring and the guide protruding ring cooperate to ensure the clamping force of the first connecting ear. The provision of the guide protruding ring facilitates the smooth passage of the guide protruding ring through the first connecting hole, so that the flat plate protruding ring and the guide protruding ring cooperate to be located at both ends of the first connecting hole.

[0009] Preferably, the second housing is provided with a recessed mounting groove, the second connection hole being provided through the bottom of the mounting groove, and the upper end of the elastic suspension member being positioned within the mounting groove. The provision of the mounting groove facilitates accommodating the upper end of the elastic suspension member, preventing the upper end of the elastic suspension member from extending above the second housing and interfering with the arrangement of other components, thereby improving space utilization within the control box.

[0010] Preferably, the second shell is provided with a plurality of second connecting ears, each of which is provided with an elastic shock absorber. The interior of the first shell is provided with a plurality of connecting pins, each of which corresponds to the elastic shock absorber in a one-to-one manner and is connected to the second connecting ears through the connecting member, so that the outer wall of the second shell is spaced apart from the inner wall of the first shell. The elastic shock absorber is used to isolate the connecting pins to prevent the connecting member from making hard contact with the second connecting ears. The spacing between the outer wall of the second shell and the inner wall of the first shell, as well as the provision of the elastic shock absorber, are conducive to further reducing the vibration of the second shell (the vibration of the second shell caused by the small amount of vibration generated by the air pump when it is working is transmitted to the second shell) from being transmitted to the first shell, further reducing the vibration of the control box when it is working.

[0011] The preferred solution for the outer wall of the second shell and the inner wall of the first shell to be spaced apart is: the first shell includes a first cover shell with an open lower end, a first base plate that cooperates with the opening and is detachably connected to the first cover shell through a connecting piece, an upper connecting foot extending downward is provided on the top wall of the first cover shell, and a lower connecting foot extending upward is provided on the first base plate, and the upper connecting foot is inserted into the connecting hole of the elastic shock-absorbing component and then plug-fitted with the corresponding lower connecting foot, and a connection is formed through the connecting piece.

[0012] Preferably, the lower connecting leg has a hollow portion extending vertically through the first base plate. An elastic vibration-damping foot is provided below the first base plate, inserted upward into the lower end of the hollow portion. The provision of the elastic vibration-damping foot helps reduce the transmission of vibration generated by the control box during operation to the supporting structure (such as a bedside table, table, or mattress), further reducing the impact of vibration from the control box during operation on the user.

[0013] The second technical solution of the present invention is as follows: a pillow comprising an outer shell, an airbag disposed within the outer shell, and connected to a control box via an external air tube. The control box is characterized in that the control box is the aforementioned multiple vibration-damping control box. Elastic suspension members are employed to reduce the transmission of operating vibrations of the air pump to the second outer shell; the outer wall of the second outer shell is spaced from the inner wall of the first outer shell, and elastic shock-absorbing members are provided to reduce the transmission of vibrations from the second outer shell to the first outer shell; and elastic vibration-damping feet are employed to reduce the transmission of vibrations from the first outer shell to an object supporting the control box. These multiple vibration-damping measures effectively reduce the impact of vibrations on the user.

[0014] The present invention has the following beneficial effects: 1. The elastic suspension member is used to reduce the transmission of the air pump's operating vibration to the second housing, thereby reducing the vibration of the second housing and facilitating the reduction of vibration of the entire control box. 2. The spacing between the outer wall of the second housing and the inner wall of the first housing and the provision of the elastic shock-absorbing member reduce the transmission of vibration from the second housing to the first housing, thereby reducing the vibration of the first housing and facilitating the reduction of vibration of the entire control box. 3. The elastic vibration-damping foot is used to reduce the transmission of vibration from the first housing to the object supporting the control box, thereby effectively reducing the vibration of the supporting object and the noise generated by the vibration, thereby reducing the impact of the vibration and noise on the supporting object on the user, and further effectively reducing the impact of the vibration on the user.

[0022] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0023] Example 1: Figure 1-Figure 5 As shown, a multiple vibration damping control box includes a shell, an air pump 3 arranged in the shell, a circuit board 4 for controlling the operation of the air pump 3, and an air path mechanism connected to the air pump 3.

[0024] One of the differences between this technical solution and the prior art is that the shell includes a first shell 1, a second shell 2 arranged inside the first shell 1 and cooperating with the first shell 1 for noise reduction, the air pump 3 and the air path mechanism are arranged in the inner cavity of the second shell 2, and the air pump 3 is suspended on the top wall of the second shell 2.

[0025] In this technical solution, a second housing 2 is added within the first housing 1, and an air pump 3 is suspended on the top wall of the second housing 2. The effect is that, since the vibration of the air pump 3 during operation is the main vibration source, absorbing and isolating the vibration of the air pump 3 is an effective vibration and noise reduction solution. Specifically, the vibration of the air pump 3 is absorbed by the elastic suspension member 6 that suspends the air pump 3, significantly reducing the vibration of the air pump 3 during operation from being transmitted to the second housing 2 and the first housing 1 in sequence. This reduces the impact of the vibration of the air pump 3 on the normal and effective use of the pillow 22, and helps maintain and improve the user's normal rest and sleep quality.

[0026] At the same time, the second shell 2 isolates the vibration transmitted to the second shell 2 by the inflation and deflation component, so that the vibration of the inflation and deflation component can rarely be transmitted to the first shell 1, thereby achieving the purpose of reducing the vibration generated when the inflation and deflation component is working, and further reducing the noise generated by the vibration, which is ultimately beneficial to keeping the use environment of the pillow 22 quiet, and further beneficial to improving the user's rest and sleep quality.

[0027] The above technical solution is then further demonstrated and explained to make it more perfect and further improve the vibration reduction and noise reduction effect:

[0028] In actual use, a fixing sleeve 5 is placed over the air pump 3, and an elastic suspension member 6 is provided on the fixing sleeve 5. The air pump 3 is suspended from the top wall of the second housing 2 via the elastic suspension member 6. The provision of the elastic suspension member 6 effectively absorbs vibrations generated by the air pump 3 during operation, reducing the transmission of vibrations generated by the air pump 3 to the second housing 2, and ultimately effectively reducing vibrations generated by the control box 23 during operation. The fixing sleeve 5 can be a rigid fixing sleeve 5 or an elastic fixing sleeve 5 with a certain clamping force (to prevent the air pump 3 from being released from the fixing sleeve 5).

[0029] In actual application, there are at least two fixing sleeves 5 (at least two fixing sleeves 5 are conducive to the stable suspension of the air pump 3 and further reduce the vibration generated when the air pump 3 is working. In this embodiment, two fixing sleeves 5 are preferably fixed at corresponding positions at both ends of the air pump 3), which are respectively sleeved on the two end parts of the air pump 3. A first connecting ear 7 is provided on the fixing sleeve 5, and at least two clamping grooves 8 are provided on the elastic suspension member 6. The elastic suspension member 6 passes through the first connecting hole 12 on the first connecting ear 7 and the second connecting hole 13 on the second shell 2 respectively. The hole wall of the first connecting hole 12 is clamped into one of the clamping grooves 8, and the hole wall of the second connecting hole 13 is clamped into the other of the clamping grooves 8. The provision of the first connecting ear 7 and the clamping groove 8 is conducive to forming a stable and reliable connection between the fixing sleeve 5 and the elastic suspension member 6.

[0030] In practical applications, the elastic suspension member 6 is provided with a plurality of spaced convex rings, and the interval between two adjacent convex rings is the clamping groove 8. The cooperation between the convex ring and the clamping groove 8 is conducive to forming a stable and reliable connection between the elastic suspension member 6 and the first connecting ear 7.

[0031] In actual application, to facilitate efficient and reliable connection between the elastic suspension member 6 and the first connecting ear 7, the two adjacent protrusions are respectively a flat plate protrusion 9 and a guide protrusion 10. The outer end surface of the guide protrusion 10 is an outer convex guide surface, and the inner end surface is a flat surface. The guide protrusion 10 is used to guide the elastic suspension member 6 through the corresponding connecting hole so that the two protrusions are respectively clamped on the corresponding first connecting ear 7 and the second housing 2. The flat plate protrusion 9 and the guide protrusion 10 cooperate to ensure the clamping force of the first connecting ear 7. The provision of the guide protrusion 10 facilitates the smooth passage of the guide protrusion 10 through the first connecting hole 12, so that the flat plate protrusion 9 and the guide protrusion 10 cooperate to be located at both ends of the first connecting hole 12.

[0032] In actual application, in order to avoid the upper end of the elastic suspension member 6 extending to the top of the second shell 2 to interfere with the arrangement of other components, it is beneficial to improve the internal space utilization of the control box 23, a concave assembly groove 11 is provided on the second shell 2, and a second connecting hole 13 is provided through the bottom of the assembly groove 11. The upper end of the elastic suspension member 6 is placed in the assembly groove 11, so that the upper end of the elastic suspension member 6 is completely accommodated in the assembly groove 11.

[0033] In actual application, in order to space the second shell 2 from the first shell 1, the second shell 2 is provided with a plurality of second connecting ears 15, each of which is provided with an elastic shock-absorbing member 16. A plurality of connecting pins are provided inside the first shell 1, and the connecting pins correspond to the elastic shock-absorbing members 16 one-to-one and are connected to the second connecting ears 15 through a connecting member, so that the outer wall of the second shell 2 is spaced from the inner wall of the first shell 1, and the elastic shock-absorbing member 16 is used to isolate the connecting pins to avoid hard contact between the connecting member and the second connecting ear 15. The spacing of the outer wall of the second shell 2 from the inner wall of the first shell 1 and the provision of the elastic shock-absorbing member 16 are conducive to further reducing the vibration of the second shell 2 (the vibration of the second shell 2 caused by the small amount of vibration generated by the air pump 3 when it is working is transmitted to the second shell 2) from the first shell 1, further reducing the vibration of the control box 23 when it is working.

[0034] In actual application, the preferred scheme for the outer wall of the second shell 2 and the inner wall of the first shell 1 to be spaced apart is: the first shell 1 includes a first cover shell 17 with an open lower end, and a first base plate 18 that cooperates with the opening and is detachably connected to the first cover shell 17 through a connecting piece. The top wall of the first cover shell 17 is provided with an upper connecting foot 19 extending downward, and the first base plate 18 is provided with a lower connecting foot 20 extending upward. The upper connecting foot 19 is inserted into the connecting hole of the elastic shock absorber 16 and then plugged into the corresponding lower connecting foot 20, and a connection is formed through the connecting piece.

[0035] In actual application, in order to further reduce the vibration generated when the control box 23 is working and transmitted to the supporting body (such as a bedside table, table or mattress, etc.) supporting the control box 23, and further reduce the impact of the vibration when the control box 23 is working on the user, the lower connecting foot 20 has a hollow part that passes through the upper and lower parts, and the hollow part passes through the first bottom plate 18. An elastic vibration-damping foot 21 is provided below the first bottom plate 18 and is inserted into the lower end of the hollow part from bottom to top.

[0036] In actual use, the inflation and deflation components include an air pump 3, a solenoid valve 27 connected to the air pump 3, a fixing platform 26 for fixing the solenoid valve 27, a control line connected to the air pump 3, and several air pipes connected to the air pump 3. To further improve the vibration and noise reduction effect of the control box 23, a buffer noise reduction box 28 is installed on the air pipe to moderate the gas flow velocity in the air pipe and eliminate gas vortexes in the air pipe, thereby achieving the effect of vibration and noise reduction.

[0037] In practice, a fixing platform 26 is provided within the second housing 2 to secure a solenoid valve 27; the solenoid valve 27 is mounted below the fixing platform. A third connecting lug 29 is provided on the side of the fixing platform 26, and an elastic shock-absorbing member 16 is mounted on the third connecting lug 29 and engages with the third connecting lug 29. A third connecting leg extends downward from the inside of the second housing 2, passes through the elastic shock-absorbing member 16, and is then secured to the fixing platform 26 via a gasket and threaded connector.

[0038] In actual application, in order to facilitate the installation of the second housing 2, the second housing 2 includes a second shell cover 24 with an open lower end, and a second bottom plate 25 that cooperates with the opening and is detachably connected to the second cover through a connector.

[0039] In actual application, in order to facilitate the operation of the control box 23 , the circuit board 4 in the control box 23 is fixed to the inner side of the top wall of the first housing 17 .

[0040] Example 2: Figure 6 As shown, the technical solution of the second technical subject of the present invention is: a pillow 22, including an outer shell, an air bag arranged in the outer shell, and connected to the control box 23 through an external air tube.

[0041] The difference between this technical solution and the prior art is that the control box 23 is the multiple vibration reduction control box described in Example 1.

[0042] In the present technical solution, the main means of achieving the vibration reduction and noise reduction effect are: 1. Using elastic suspension parts 6 to reduce the transmission of the working vibration of the air pump 3 to the second shell 2. Using the spacing setting of the outer wall of the second shell 2 and the inner wall of the first shell 1 and the setting of the elastic shock-absorbing parts 16 to reduce the transmission of vibration from the second shell 2 to the first shell 1. 3. Using elastic vibration-damping feet 21 to reduce the transmission of vibration from the first shell 1 to the object supporting the control box 23. The above-mentioned multiple vibration reduction means are used to effectively reduce the impact of vibration on the user.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations are possible in the above embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
