Description

Technical Field

[0001] The utility model relates to a control box and bedding using the control box, in particular to a multiple noise reduction 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 lines connecting the solenoid valve and the air pump, and several air pipes connected to the air pump. During 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 high noise level. Simultaneously, the flow of air also generates noise. However, pillows are used in relatively quiet resting or sleeping environments. 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, leading to the user disabling the massage or height adjustment function. This 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 utility model is to solve the above-mentioned problems existing in the prior art and to provide a multiple noise reduction control box and a pillow using the same. The air pump is arranged in the noise reduction pump shell, and the noise reduction pump shell can play a role in sound insulation and noise reduction, thereby helping to reduce the noise generated during the use of the pillow.

[0004] The above technical objectives of the present invention are mainly solved by the following technical solutions:

[0005] The technical solution of the first technical subject involved in the present utility model is: a multiple noise reduction 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 it also includes a noise reduction pump housing, the air pump being disposed within the noise reduction pump housing, and the noise reduction pump housing being used to isolate the noise generated by the air pump to achieve the purpose of reducing the noise of the air pump. Since the noise generated by the operation of the air pump is the main noise source, the present technical solution disposes the air pump within the noise reduction pump housing, and the noise reduction pump housing can play a role in sound insulation and noise reduction, thereby helping to reduce the noise generated during the use of the pillow.

[0006] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the noise reduction pump housing is suspended on the top wall of the housing via a suspension assembly, so that the air pump is suspended in the air, and the inner cavity shape of the noise reduction pump housing is adapted to the shape of the housing of the air pump. In order to further reduce the noise during operation of the control box, it is further preferred to hang the air pump on the top wall of the housing. The noise reduction principle is as follows: since the vibration of the air pump during operation is the main vibration source, absorbing the vibration of the air pump is an effective vibration reduction method. Reducing the vibration absorption of the air pump can significantly reduce the noise reduction of the control box during operation.

[0007] 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 when working and is transmitted to the outer shell in turn, thereby reducing the impact of the air pump vibration on the normal and effective use of the pillow, and is conducive to maintaining and improving the user's normal rest and sleep quality.

[0008] Preferably, the shell includes a first shell and a second shell arranged in the inner cavity of the first shell, an air layer is provided between the first shell and the second shell, and the noise reduction pump shell is suspended on the top wall of the second shell by a suspension assembly, so that the air pump is suspended. The air pump is suspended on the top wall of the second shell, and the vibration of the air pump is absorbed by the suspension assembly that suspends the air pump, which greatly reduces the vibration of the air pump when it is working and is transmitted to the second shell and the first shell in turn. Because the second shell first absorbs and isolates the vibration and noise, the vibration and noise transmitted to the second shell by the inflation and deflation assembly are greatly reduced, thereby achieving the purpose of reducing the vibration generated when the inflation and deflation assembly is working, and further reducing the noise generated by the vibration, which is ultimately beneficial to keeping the pillow use environment quiet, and further beneficial to improving the user's rest and sleep quality.

[0009] Preferably, a connecting lug is provided on the outer wall of the noise reduction pump housing, and the suspension assembly is provided on the connecting lug, wherein the suspension assembly is suspended by an elastic shock-absorbing member. The elastic shock-absorbing member suspension is conducive to fully absorbing the vibration of the air pump, significantly reducing the vibration of the air pump from being transmitted to the second housing, thereby greatly reducing the vibration of the air pump from being transmitted to the first housing, thereby greatly reducing the noise generated.

[0010] Preferably, the noise-reducing pump housing includes a soundproof outer shell and a soundproof damping shell disposed within the soundproof outer shell. Both the soundproof outer shell and the soundproof damping shell have openable inner cavities, and the air pump is disposed within the inner cavity of the soundproof damping shell. The soundproof damping shell further enhances the sound insulation effect and reduces noise transmission from the noise-reducing pump housing. The soundproof outer shell is used to seal the air pump and reduce airborne noise. Both the soundproof outer shell and the soundproof damping shell have openable inner cavities, facilitating easy assembly and disassembly of the air pump.

[0011] Preferably, the sound insulation and damping shell is compounded on the inner wall of the sound insulation outer shell, and the sound insulation outer shell includes two sound insulation outer half shells with one end open, and the two open ends of the two sound insulation outer half shells are connected by a connecting piece to form a sound insulation sealing connection, and each of the sound insulation outer half shells and the bottom wall of the sound insulation and damping shell are provided with air holes, and the corresponding air pipes on the air path mechanism respectively pass through the corresponding air holes to form connections with the air inlet and air outlet of the air pump.

[0012] Preferably, the air pipe is interference-fitted with the wall of the air hole. Alternatively, the air inlet and the air outlet of the air pump usually have connecting pipe sections, which pass through the corresponding air holes and form an interference fit.

[0013] Preferably, the air pipe connected to the air inlet of the air pump is connected to a buffer air box, and the air outlet of the air pump is connected to another buffer air box and a solenoid valve. The buffer air box is used to reduce noise. The provision of the buffer air box facilitates temporarily buffering the gas entering or exiting the air pump, reducing the gas flow rate and the possibility of vortexes, thereby reducing the noise generated by the gas flow.

[0014] Preferably, the solenoid valve is mounted on a vibration-damping platform for reducing vibration and noise. The air path mechanism, buffer air box, solenoid valve, and vibration-damping platform are all located within the second housing. The vibration-damping platform is designed to reduce vibration generated during operation of the solenoid valve, thereby reducing the noise caused by the vibration. In this technical solution, components prone to vibration and / or noise are located within the second housing. The second housing provides the primary sound insulation and noise reduction functions, reducing the vibration and noise transmitted to the first housing, thereby reducing the vibration and noise of the entire control box during operation, achieving multiple noise reduction objectives.

[0015] The technical solution of the second technical theme involved in the present utility model is as follows: a pillow comprising an outer shell, an air bag arranged in the outer shell, connected to a control box via an external air pipe, characterized in that the control box is the aforementioned multiple noise reduction control box.

[0026] The technical solution of the present invention will be further specifically described below with reference to the embodiments and the accompanying drawings.

[0027] Example 1: Figure 1-Figure 7As shown, the technical solution of the first technical subject involved in the utility model is:

[0028] A multiple noise reduction control box comprises a housing, an air pump 3 arranged in the housing, a circuit board 4 for controlling the operation of the air pump 3, and an air path mechanism connected to the air pump 3.

[0029] The difference between this technology and the prior art is that the multiple noise reduction control box 13 also includes a noise reduction pump housing 14, and the air pump 3 is arranged in the noise reduction pump housing 14. The noise reduction pump housing 14 is used to isolate the noise generated by the air pump 3 to achieve the purpose of noise reduction of the air pump 3.

[0030] Since the noise generated when the air pump 3 is working is the main noise source, the technical solution sets the air pump 3 in the noise reduction pump housing 14. The noise reduction pump housing 14 can play a role in sound insulation and noise reduction, thereby helping to reduce the noise generated during the use of the pillow 12.

[0031] Next, we will explain the above scheme in detail:

[0032] In actual applications, to further reduce the noise generated by the control box 13 during operation, the noise-reducing pump housing 14 is suspended from the top wall of the housing via the suspension assembly 5, allowing the air pump 3 to be suspended in mid-air. The inner cavity shape of the noise-reducing pump housing 14 is adapted to the shape of the housing of the air pump 3. Further preferably, the air pump 3 is suspended from the top wall of the housing. The noise reduction principle is as follows: since the vibration of the air pump 3 during operation is the primary source of vibration, absorbing the vibration of the air pump 3 is an effective vibration reduction method. Reducing the vibration absorption of the air pump 3 can significantly reduce the noise generated by the operation of the control box 13.

[0033] Specifically, the vibration of the air pump 3 is absorbed by the elastic suspension parts that suspend the air pump 3, which greatly reduces the vibration of the air pump 3 when working and is transmitted to the outer shell in turn, thereby reducing the impact of the vibration of the air pump 3 on the normal and effective use of the pillow 12, and is conducive to maintaining and improving the user's normal rest and sleep quality.

[0034] In actual application, in order to further increase the noise reduction effect, the shell includes a first shell 1 and a second shell 2 arranged in the inner cavity of the first shell 1, and there is an air layer between the first shell 1 and the second shell 2. The noise reduction pump shell 14 is suspended on the top wall of the second shell 2 through a suspension component 5, so that the air pump 3 is suspended in the air.

[0035] In this technical solution, the air pump 3 is suspended on the top wall of the second shell 2, and the vibration of the air pump 3 is absorbed by the suspension component 5 that suspends the air pump 3, which greatly reduces the vibration of the air pump 3 when it is working and is transmitted to the second shell 2 and the first shell 1 in turn. Because the second shell 2 first absorbs and isolates the vibration and noise, the vibration and noise transmitted to the second shell 2 by the inflation and deflation component are greatly reduced, 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 12 quiet, and further beneficial to improving the user's rest and sleep quality.

[0036] In actual application, in order to facilitate the connection of the suspension assembly 5, a connecting lug 6 is provided on the outer wall of the noise reduction pump housing 14, and the suspension assembly 5 is mounted on the connecting lug 6. The suspension assembly 5 is suspended by an elastic shock-absorbing member. The elastic shock-absorbing member suspension is conducive to fully absorbing the vibration of the air pump 3, significantly reducing the vibration of the air pump 3 from being transmitted to the second housing 2, and further greatly reducing the vibration of the air pump 3 from being transmitted to the first housing 1, thereby greatly reducing the noise generated.

[0037] In actual applications, to further improve the noise reduction effect, the noise reduction pump housing 14 includes a soundproof housing 7 and a soundproof damping housing 8 disposed within the soundproof housing 7. Both the soundproof housing 7 and the soundproof damping housing 8 are housings with openable inner cavities, and the air pump 3 is disposed within the inner cavity of the soundproof damping housing 8. The soundproof damping housing 8 helps further improve the sound insulation effect and reduce the amount of noise transmitted from the noise reduction pump housing 14. The soundproof housing 7 is used to seal the air pump 3 and reduce airborne noise. Both the soundproof housing 7 and the soundproof damping housing 8 are housings with openable inner cavities, which facilitates the disassembly and assembly of the air pump 3.

[0038] In actual application, the sound insulation and damping shell 8 is compounded on the inner wall of the sound insulation outer shell 7. The sound insulation outer shell 7 includes two sound insulation outer half shells with one end open, and the two open ends of the two sound insulation outer half shells are connected by a connecting piece to form a sound insulation sealing connection. Each of the sound insulation outer half shells and the bottom wall of the sound insulation and damping shell 8 is provided with an air hole 9, and the corresponding air pipes on the air path mechanism respectively pass through the corresponding air holes 9 to form a connection with the air inlet and air outlet of the air pump 3.

[0039] In actual applications, the air pipe has an interference fit with the wall of the air hole 9, that is, the corresponding air pipe on the air path mechanism passes through the air hole 9 and enters the interior of the noise reduction pump housing 14 to form a connection with the air inlet and air outlet of the air pump 3. Alternatively, in actual applications, the air inlet and air outlet of the air pump 3 usually have connecting pipe sections, which respectively pass through the corresponding air hole 9 and form an interference fit.

[0040] In actual use, to reduce the noise generated by the airflow in the air path mechanism, the air pipe connected to the air inlet of the air pump 3 is connected to a buffer air box 10, and the air outlet of the air pump 3 is connected to another buffer air box 10 and a solenoid valve 15. The buffer air box 10 is used to reduce noise. The provision of the buffer air box 10 helps temporarily buffer the gas entering or exiting the air pump 3, reducing the gas flow rate and the possibility of vortexes, thereby reducing the noise generated by the gas flow.

[0041] In actual use, to reduce the noise generated by the vibration of the solenoid valve 15 during operation, the solenoid valve 15 is disposed on a vibration-damping platform 11 for reducing vibration and noise. The air path mechanism, buffer air box 10, solenoid valve 15, and vibration-damping platform 11 are all disposed within the second housing 2. The provision of the vibration-damping platform 11 serves to reduce the vibration generated during operation of the solenoid valve 15, thereby reducing the noise caused by vibration. In this technical solution, components prone to vibration and / or noise are disposed within the second housing 2. The second housing 2 performs the primary sound insulation and noise reduction functions, reducing the vibration and noise transmitted to the first housing 1, thereby reducing the vibration and noise of the entire control box 13 during operation, achieving the purpose of multiple noise reduction.

[0042] In summary, the present technical solution at least adopts a noise reduction pump shell 14 to reduce the noise of the air pump 3 which mainly causes noise due to vibration, adopts an elastic suspension component 5 to suspend the noise reduction pump shell 14 to further reduce the vibration generated by the air pump 3 from being transmitted to the contacting parts for noise reduction, adopts a first shell 1 to cooperate with a second shell 2 so that the air pump 3 and other parts that are prone to vibration and / or noise are arranged in the second shell 2 for noise reduction, adopts a buffer air box 10 to reduce the noise generated by the gas flow in the inflation and deflation components, adopts a vibration reduction platform 11 to reduce the vibration and noise generated by the operation of the solenoid valve 15, and one or more means to reduce the working noise of the control box 13, thereby helping to keep the use environment of the pillow 12 quiet, and further helping to improve the user's rest and sleep quality.

[0043] Example 2: The technical solution of the second technical subject involved in the utility model: a pillow, including a cover, an air bag arranged in the cover, connected to the control box 13 through an external air tube, characterized in that the control box 13 is the aforementioned multiple noise reduction control box.

[0044] As for the technical solution of the pillow 12, since the technical solution of Example 1 at least adopts a noise-reducing pump shell 14 to reduce the noise of the air pump 3 whose noise is mainly caused by vibration, adopts an elastic suspension component 5 to suspend the noise-reducing pump shell 14 to further reduce the vibration generated by the air pump 3 from being transmitted to the contacting parts for noise reduction, adopts the first shell 1 to cooperate with the second shell 2 so that the air pump 3 and other parts that are prone to vibration and / or noise are arranged in the second shell 2 for noise reduction, adopts a buffer air box 10 to reduce the noise generated by the gas flow in the inflation and deflation components, and adopts a vibration reduction platform 11 to reduce the vibration and noise generated by the operation of the solenoid valve 15, one or more means are used to reduce the noise of the control box 13, which is beneficial to keep the pillow 12 involved in this embodiment in a quiet use environment during use, and further beneficial to improve the user's rest and sleep quality.
