Description

Technical Field

[0001] The utility model relates to the field of electronic control and furniture products, in particular to a noise reduction control box and a pillow using the same. Background Art

[0002] A pillow that can automatically adjust the height of the pillow and / or has a massage function includes a pillow body, an airbag arranged in the pillow body, and a control box that controls the inflation or deflation of the airbag (referred to as inflation and deflation). The control box includes a control box body, a control board arranged inside the control box body, and an inflation and deflation assembly connected to the control board, and the inflation and deflation assembly is connected to the airbag in the pillow body through an air pipe. Since the inflation and deflation assembly is prone to generate a large noise during the inflation or deflation process, and the pillow is used in a quiet rest or sleep environment, a large noise will affect the user's rest or sleep quality, and in severe cases, it is easy to cause the user to be unable to rest or sleep.

[0003] In addition, the existing control box for controlling the inflation and deflation of airbags is relatively large in size. In order to meet the user's demand for miniaturization of corresponding technological products, the control box needs to be miniaturized. However, the composition and connection method of the inflation and deflation components cannot be applied to smaller control boxes. Summary of the invention

[0004] The purpose of the utility model is to solve the above-mentioned problems existing in the prior art and to provide a noise reduction control box and a pillow using the same. By adding air storage boxes, no matter in the process of inflating the airbag or deflating the airbag, the gas first passes through the air storage box for buffering, weakening the air flow speed and air pressure, greatly reducing the noise caused by rapid high-pressure airflow, and achieving the purpose of reducing noise.

[0005] The above technical purpose of the utility model is mainly solved by the following technical solutions: a noise reduction control box, including an outer shell, an air charging and discharging assembly arranged in the inner cavity of the outer shell, the air charging and discharging assembly includes an air pump, and is characterized in that the air charging and discharging assembly also includes an air charging air storage box, an intermediate air storage box and an air deflation air storage box, the air charging air storage box is used to buffer and store the air generated by the air pump, the intermediate air storage box is used to buffer and store the gas coming out of the air charging air storage box for inflating the airbag for noise reduction or for buffering and storing the gas released from the airbag for noise reduction before entering the air deflation air storage box, and the air deflation air storage box is used to buffer and discharge the gas again for noise reduction. In the prior art, whether in the process of inflating the airbag or in the process of deflating the airbag, the gas must pass through the trachea. When passing through the trachea, the air flow velocity and air pressure increase sharply, thereby generating great shocks and vibrations, thereby causing great noise. The technical solution adds each gas storage box, so that the gas from the air pump and the gas from the solenoid valve first enter the corresponding gas storage box, and the corresponding gas storage box can increase the airflow channel sharply, and the airflow speed and air pressure are sharply reduced, thereby greatly reducing the shock and vibration caused by the airflow speed and air pressure, thereby achieving the purpose of reducing noise. For example, the gas passing through the solenoid valve will cause the airflow speed to change, and the intermediate gas storage box and the deflated gas storage box avoid the noise problem caused by the gas flowing out of the solenoid valve being directly transported to the airbag or directly discharged to the outside.

[0006] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: the air pump is suspended in the inner cavity of the outer shell by a soft supporting suspension part, which is used to reduce the vibration generated when the air pump is working and transmitted to the outer shell, and the inflation and deflation assembly also includes at least two solenoid valves, and the solenoid valves are elastically buffered with the outer shell. The elastic buffer is used to absorb the vibration generated when the solenoid valve is working and reduce the vibration transmitted to the outer shell. This technical solution absorbs the vibration generated when the air pump and the solenoid valve are working respectively by means of soft supporting suspension parts and elastic buffering, reduces the noise generated between the outer shell and surrounding objects due to vibration, and achieves the purpose of further noise reduction.

[0007] In order to further improve the noise reduction effect, an inner shell is arranged in the inner cavity of the outer shell, the air charging and discharging assembly is arranged in the inner cavity of the inner shell, the air pump is suspended in the inner cavity of the inner shell through a soft supporting suspension, and the air charging and discharging assembly also includes at least two solenoid valves, and the solenoid valves are elastically buffered with the inner shell. By adding an inner shell, the air charging and discharging assembly is isolated in the inner cavity of the inner shell, and the vibration and noise generated when the air charging and discharging assembly is working are isolated by the inner shell, so as to achieve the purpose of vibration reduction and noise reduction. In this technical solution, the elastic buffering cooperation between the solenoid valve and the inner shell can achieve the same technical effect as the elastic buffering cooperation between the solenoid valve and the outer shell involved in the aforementioned technical solution, and both are used to reduce noise.

[0008] Preferably, the solenoid valve is arranged on a first mounting seat, and an elastic buffer connection is formed between a connection portion of the first mounting seat and the inner housing via a first elastic buffer member, and the first elastic buffer member absorbs vibration and part of noise during operation of the solenoid valve.

The effect and working principle of the second elastic buffer are equivalent to those of the first elastic buffer, and are used to isolate the vibration on the inner shell from being transmitted to the outer shell.

[0012] Preferably, the air outlet of the inflation air storage box is connected to the second port of each of the solenoid valves, the first air vent of the intermediate air storage box is connected to the first port of the solenoid valve, the second air vent of the intermediate air storage box is used to form a connection with the airbag, and the air inlet of the deflation air storage box is connected to the third port of each of the solenoid valves.

[0013] Preferably, in order to rationally utilize the internal space of the inner shell or the outer shell and make the volume of each air storage box as large as possible, the inflation air storage box, the intermediate air storage box and the deflation air storage box are all U-shaped, and a limiting structure is provided on the inner wall of the inner shell in the inner cavity of the outer shell, and the limiting structure is used to limit the deflation air storage box.

This technical solution adopts a noise reduction control box with each air storage box, which can buffer the airflow during the process of inflating or deflating the airbag, greatly reducing the airflow velocity and air pressure, thereby reducing the shock and vibration caused by the airflow and air pressure, so as to achieve the purpose of reducing noise. In addition, the effect of vibration reduction and noise reduction is further improved by adopting soft supporting suspension parts, first elastic buffer parts, second elastic buffer parts and adding inner shells.

DETAILED DESCRIPTION

[0029] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0030] Example 1: Figure 1-Figure 11 As shown, the technical solution of the first technical subject involved in the utility model is: a noise reduction control box 17, including an outer shell, and an air charging and discharging component arranged in the inner cavity of the outer shell, and the air charging and discharging component includes an air pump 2.

[0031] The difference between the present technical solution and the prior art is that the inflation and deflation assembly also includes an inflation air storage box 13, an intermediate air storage box 14 and a deflation air storage box 15. The inflation air storage box 13 is used to buffer and store the inflation generated by the operation of the air pump 2, and the intermediate air storage box 14 is used to buffer and store the gas coming out of the inflation air storage box 13 for inflating the airbag for noise reduction or for buffering and storing the gas released from the airbag for noise reduction and then entering the deflation air storage box 15, and the deflation air storage box 15 is used to buffer and discharge the gas again for noise reduction.

[0032] In the prior art, whether in the process of inflating the airbag or deflating the airbag, the gas must pass through the trachea. When passing through the trachea, the airflow velocity and air pressure increase sharply, thereby generating great shocks and vibrations, thereby causing great noise. However, the technical solution adds each gas storage box, so that the gas from the air pump or the gas coming out through the solenoid valve first enters the corresponding gas storage box. The corresponding gas storage box increases the airflow channel sharply, and the airflow velocity and air pressure decrease sharply, thereby greatly reducing the shocks and vibrations caused by the airflow velocity and air pressure, thereby achieving the purpose of reducing noise. For example, the gas passing through the solenoid valve will cause a change in the airflow velocity, and the intermediate gas storage box and the deflated gas storage box avoid the noise problem caused by the gas flowing out of the solenoid valve being directly transported to the airbag or directly discharged to the outside world.

[0033] In actual application, the air pump 2 is suspended in the inner cavity of the outer shell by a soft supporting suspension 3, which is used to reduce the vibration generated when the air pump 2 is working and transmitted to the outer shell. The inflation and deflation assembly also includes at least two solenoid valves 4 (including a first solenoid valve, a second solenoid valve...the Nth solenoid valve), and the solenoid valve 4 is elastically buffered with the outer shell.

[0034] like Figure 6 As shown, in Figure 6A, B, C, and D represent the solenoid valve A port, the solenoid valve B port, the solenoid valve C port, and the solenoid valve D port, respectively. The first solenoid valve and the second solenoid valve are connected to the corresponding tracheal ports of two independent airbags or two independent airbag groups through the intermediate air storage box 14 to realize the independent inflation and deflation control of different airbag parts in the pillow. To further explain, the intermediate air storage box 14 includes the first intermediate air storage box, the second intermediate air storage box...the Nth intermediate air storage box, which can be an intermediate air storage box connected to the airbags, or each intermediate air storage box can be connected to the corresponding tracheal port of an independent airbag. In specific applications, the Nth intermediate air storage box can be connected to other air ports according to the user's own connection, and the number of air ports can be determined by the user.

[0035] Specifically, the elastic buffer is used to absorb the vibration generated when the solenoid valve 4 is working, and reduce the vibration transmitted to the outer shell. This technical solution absorbs the vibration generated when the air pump 2 and the solenoid valve 4 are working respectively by means of the soft supporting suspension 3 and the elastic buffer, reduces the noise generated by the outer shell and the surrounding objects due to the vibration, and achieves the purpose of further noise reduction.

[0036] In practical applications, when the solenoid valve 4 is a two-position three-way solenoid valve, Figure 7-Figure 9 As shown, two two-position three-way solenoid valves are connected in series, and the right solenoid valve (i.e. Figure 7 The solenoid valve D port of the right solenoid valve in the figure (hereinafter referred to as the right solenoid valve) is a closed port. Among them, the solenoid valve B port 24 of the two two-position three-way solenoid valves is used to connect to the intermediate gas storage box 14, and the solenoid valve C port 25 is used to connect to the deflated gas storage box 15. One of the solenoid valves (i.e. Figure 7 The left electromagnetic valve in the middle, referred to as the left electromagnetic valve, is connected to the gas storage box 13 through the electromagnetic valve A port 23 on it, and the electromagnetic valve D port 26 on it (i.e. the left electromagnetic valve) is used to connect another electromagnetic valve (i.e. Figure 7 The solenoid valve A port 23 on the right solenoid valve in the figure (hereinafter referred to as the right solenoid valve) connects the two solenoid valves in series. In practical applications, the solenoid valve A port 23 on one solenoid valve and the solenoid valve D port 26 on the other solenoid valve are connected in any state. Figure 7 As shown, when both solenoid valves are not powered, the solenoid valve B port 24 and the solenoid valve C port 25 are connected to each other for airbag deflation. Figure 8 As shown, when both solenoid valves are powered on, the solenoid valve A port 23 and the solenoid valve B port 24 are connected for airbag inflation. Fig. 9 As shown, when the left solenoid valve is energized and the right solenoid valve is not energized, the left solenoid valve inflates the airbag connected thereto and the right solenoid valve deflates the airbag connected thereto.

[0037] In practical applications, when the solenoid valve 4 is a two-position two-way solenoid, Fig.10 and Fig.11As shown, three two-position two-way solenoid valves are connected in series, the solenoid valve C port 25 on each solenoid valve is a closed port (i.e., no air is vented), the solenoid valve A port 23 on the left solenoid valve is connected to the inflation gas storage box 13, the solenoid valve B port 24 on the right solenoid valve is connected to the deflation gas storage box 15, the solenoid valve B port 24 on the left solenoid valve and the middle solenoid valve is connected to the middle gas storage box 14, the solenoid valve A port 23 on the middle solenoid valve is connected to the solenoid valve D port 26 on the left solenoid valve, the solenoid valve D port 26 on the middle solenoid valve is connected to the solenoid valve A port 23 on the right solenoid valve, and the solenoid valve D port 26 on the right solenoid valve is a closed port. Fig.10 As shown in FIG. 11 , when the left solenoid valve and the middle solenoid valve are both energized and the right solenoid valve is not energized, it is used to inflate the airbag.

[0038] Example 2: Figure 1-11 As shown, in order to further improve the noise reduction effect, an inner shell is arranged in the inner cavity of the outer shell, the inflation and deflation assembly is arranged in the inner cavity of the inner shell, the air pump 2 is suspended in the inner cavity of the inner shell through a soft supporting suspension 3, and the inflation and deflation assembly also includes at least two solenoid valves 4, and the solenoid valves 4 are elastically buffered with the inner shell.

[0039] By adding an inner shell, the inflation and deflation components are isolated in the inner cavity of the inner shell, and the vibration and noise generated by the inflation and deflation components during operation are isolated by the inner shell, thereby achieving the purpose of reducing vibration and noise. The elastic buffering cooperation between the solenoid valve 4 and the inner shell in this technical solution can achieve the same technical effect as the elastic buffering cooperation between the solenoid valve 4 and the outer shell involved in the aforementioned technical solution, both of which are used to reduce noise.

[0040] In practical applications, the solenoid valve 4 is arranged on the first mounting seat 5, and an elastic buffer connection is formed between the connection part of the first mounting seat 5 and the inner housing through the first elastic buffer 6. The first elastic buffer 6 absorbs vibration and part of the noise of the solenoid valve 4 when it is working.

[0041] In practical applications, the first mounting seat 5 is a mounting plate or a mounting box (in Figure 1-Figure 3 , Figure 5 The structure of the mounting plate is shown in the figure. For those skilled in the art, the structure of the mounting box is understandable. In order to avoid redundancy, the corresponding structural schematic diagram is omitted). The solenoid valves 4 are fixed on the mounting plate or in the mounting box.

[0042] In practical applications, the connection part of the first mounting seat 5 is the first connecting ear 8, the first connecting ear 8 is provided with a first elastic buffer 6, and the first connecting ear 8 is fixed to the inner shell by a first connecting member (which may be a screw) passing through the first elastic buffer 6. The first elastic buffer 6 isolates the rigid first mounting seat 5, the first connecting member and the first connecting ear 8, avoiding direct contact between rigid structures, thereby facilitating vibration reduction and noise reduction.

[0043] In practical applications, the inner shell is provided with a second connecting ear 9, the second connecting ear 9 is provided with a second elastic buffer 10, the top wall and the bottom wall of the outer shell are provided with an upper connecting column 11 and a lower connecting column 12 respectively, and the second connecting member (which can be a screw) sequentially passes through the bottom wall, the lower connecting column 12, the second elastic buffer 10 and the upper connecting column 11 to form a connection, so that the inner shell is fixed in the inner cavity of the outer shell. The effect and working principle of the second elastic buffer 10 are equivalent to those of the first elastic buffer 6, and are used to isolate the vibration on the inner shell from being transmitted to the outer shell.

[0044] In practical applications, the inner shell includes an upper inner shell 20 and a lower inner shell 21, and a plurality of outwardly protruding third connecting ears are arranged on the upper inner shell 20, and a plurality of outwardly protruding fourth connecting ears are arranged on the lower inner shell 21, and the third connecting ears and the fourth connecting ears are arranged one by one, and the third connecting ears and the fourth connecting ears are connected by a connecting piece so that the upper inner shell 20 and the lower inner shell 21 are closed to form the inner shell. The provision of the third connecting ear and the fourth connecting ear, on the one hand, is conducive to ensuring that there is sufficient connection surface between the upper inner shell 20 and the lower inner shell 21 to make the connection more reliable, and on the other hand, is conducive to ensuring that there is sufficient installation space inside the inner shell, which is convenient for assembling the inflation and deflation components, and reduces the possibility of the inflation and deflation components contacting the inner shell, and is also conducive to vibration reduction and noise reduction.

[0045] In actual application, the outer shell includes a lower outer shell 9 and an upper outer shell 8. In order to hide the second connecting piece, the second connecting piece for connecting the upper connecting column 11 and the lower connecting column 12 is inserted from the bottom of the lower outer shell 6 into the connecting channel of the lower connecting column 12, and then passes through the connecting hole of the second elastic buffer 10 and is inserted into the connecting channel of the upper connecting column 11. Finally, the second connecting piece is tightened to stabilize the upper connecting column 11 and the lower connecting column 12 to fix the inner shell, while the lower outer shell 9 and the upper outer shell 8 are connected to complete the assembly of the control box 17.

[0046] In actual application, the air outlet of the inflation air storage box 13 is connected to the second port of each of the solenoid valves, the first air vent of the intermediate air storage box 14 is connected to the first port of the solenoid valve, the second air vent of the intermediate air storage box 14 is used to form a connection with the airbag, and the air inlet of the deflation air storage box 15 is connected to the third port of each of the solenoid valves.

[0047] In practical applications, in order to rationally utilize the internal space of the inner shell or the outer shell and make the volume of each gas storage box as large as possible, the inflation gas storage box 13, the intermediate gas storage box 14 and the deflation gas storage box 15 are all U-shaped, and a limiting structure is provided on the inner wall of the inner shell in the inner cavity of the outer shell, and the limiting structure is used to limit the deflation gas storage box 15.

[0048] Example 3: Fig.12 As shown, the technical solution of another technical subject involved in the present technical solution is: a pillow, comprising a pillow body 16, an airbag cushion arranged in the pillow body 16, and a control box 17 connected to the airbag cushion through an air tube.

[0049] The difference between the present technical solution and the prior art is that the control box 17 is the noise reduction control box 17 described in Example 1 or Example 2, and the purpose of noise reduction is achieved when the airbag is inflated or deflated.

[0050] Specifically, the present technical solution adopts the method of adding a noise reduction control box 17 to each air storage box, which can buffer the airflow during the process of inflating or deflating the airbag, greatly reducing the airflow velocity and air pressure, thereby reducing the shock and vibration caused by the airflow and air pressure, thereby achieving the purpose of reducing noise. In addition, the soft supporting suspension member 3, the first elastic buffer member 6, the second elastic buffer member 10 and the additional inner shell are adopted to further improve the effect of vibration reduction and noise reduction.

In the above embodiments, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
