Description

Technical Field

[0001] The utility model relates to the field of air mattresses, in particular to an integrated noise reduction air pump assembly, a noise reduction control box and a noise reduction inflatable mattress. Background Art

[0002] Existing air mattresses use a built-in control box to inflate the airbags. The control box is equipped with an air pump, a controller for controlling its inflation, and an air box for alleviating high-speed airflow. During operation, the controller controls the air pump to output air, which is then buffered by the air box and then supplied to the airbag to inflate it to achieve elastic support, or repeatedly inflate and deflate it to achieve massage. The air box buffers the high-flow air output by the air pump, reducing the noise generated by the excessively fast airflow speed, thereby achieving a noise reduction effect. The air pump and the air box inside the existing control box are separately arranged. The multiple air outlets of the air pump are connected to the air box through an independent hose to adjust the air flow rate. Multiple hoses are winding and coiled in the control box. The overall structure of the air pump assembly composed of the air pump, the air box, and the hose is complicated and not compact, which takes up space in the control box. In addition, the coiled hose is difficult to organize. The air path connections between the various components in the air pump assembly need to be assembled in the control box, and the installation speed is slow and inefficient. Utility Model Content

The air pump and air box in the air pump assembly are integrated in the same shell with a compact structure. They can be prefabricated and assembled as an integral component and placed as a whole when the control box is assembled. At the same time, the air outlet nozzle of the air pump and the air box are connected by plugging, eliminating the need for a hose connection and the need to arrange the air supply pipe.

[0004] The technical solution adopted by the utility model to solve the technical problem is: an integrated noise reduction air pump assembly, including an air pump and an air box and an air path connecting the two, an air outlet nozzle is provided on the air pump, and an air inlet connector and an air outlet connector are provided on the air box, and the air pump and the air box are arranged in a detachable shell, the air outlet nozzle is sealed and plugged with the air inlet connector to form an air path, and an opening matching the air outlet connector is provided on the shell.

The integrated air pump assembly can be prefabricated in advance and mass-produced, which is convenient for the assembly of the subsequent control box. The air pump supplies air to the air box by plugging and connecting the air outlet nozzle and the air inlet connector of the air box.

When the air outlet nozzle and the air inlet joint are plugged and connected, the inner tube wall is pressed between the air outlet nozzle and the first joint tube to achieve a sealed connection between the air outlet nozzle and the air inlet joint.

[0006] The first joint pipe is arranged in a concave hole formed by the concave surface of the gas box, and the side wall of the concave hole surrounds the first joint pipe to form an annular groove that can accommodate the outer tube wall. The first joint pipe is arranged in the concave surface of the gas box, which can further shorten the length occupied by the air inlet nozzle and the air inlet joint for plugging and connecting.

[0007] The housing is provided with a shock-absorbing assembly for shock-absorbing the air pump and the air box. The shock-absorbing assembly includes an air pump shock-absorbing sleeve and an air box shock-absorbing sleeve respectively tightly sleeved outside the air pump and the air box. The air pump shock-absorbing sleeve is suspended on the inner wall of the housing, and the air box shock-absorbing sleeve is tightly attached to the inner wall of the housing. The air pump and the air box are each equipped with a corresponding shock-absorbing sleeve. The shock-absorbing sleeve has a shock-absorbing effect to alleviate the vibration generated by the operation of the air pump and the air box, and also has the function of installation and positioning. The air pump shock-absorbing sleeve suspends the air pump in the housing, and the air box shock-absorbing sleeve is tightly attached to the inner wall of the housing so that the air box is tightly arranged in the housing.

[0008] The air pump shock-absorbing sleeve is provided with a plurality of through holes corresponding to the shape and number of the air pump, and the air pump shock-absorbing sleeve is provided with a plurality of hanging ears with holes along the periphery, and the inner wall of the shell is provided with a mounting column for receiving the hanging ears; the air box shock-absorbing sleeve is provided with an annular hole matching the shape of the air box.

[0009] The air pump shock-absorbing sleeve is formed by connecting annular bodies arranged in a row and arc-shaped edges of two adjacent annular bodies in an integral manner. The inner periphery of the annular bodies surrounds the through hole. The hanging ears are arranged on the outer periphery of the annular bodies at both ends of the air pump shock-absorbing sleeve, and the hanging ears can be folded and retracted along the length direction. The annular bodies are tightly fitted to install the air pump through the inner edge holes, the arc-shaped edges connect all the annular bodies into an integrated structure, and the hanging ears suspend the air pump shock-absorbing sleeve and the air pump in the shell; when the air pump generates vibration during operation, the hanging ears and the arc-shaped edges can be elastically deformed to absorb and alleviate the vibration generated by the operation of the air pump, and prevent the vibration from spreading outward and affecting other components.

[0010] The number of the air pumps is 2 to 4, and the air box is provided with an air inlet connector and an air outlet connector in parallel with the number of air pumps.

The air pump assembly in the control box adopts the aforementioned integrated noise reduction air pump assembly, which has a compact structure and high integration, is convenient for control box assembly and subsequent maintenance and replacement, and there is no need to reconnect the hose to clear the air path and organize the hose every time. It can also effectively save the internal space of the base box, creating conditions for reducing the size of the control box. The integrated air pump assembly is suspended in the inner cavity of the base box by a suspension with a shock-absorbing effect. The suspension uses shock-absorbing feet to alleviate the working vibration of the air pump assembly and its impact on the base box, thereby achieving overall noise reduction of the control box and preventing the vibration of the control box from affecting the use of the mattress. The elastic hanging rod can further alleviate the vibration generated by the operation of the air pump assembly through its own deformation.

[0012] The shell is hung on the suspension, and sound-absorbing cotton is attached to the inner wall of the bottom box and / or the inner wall of the box cover. The integrated air pump assembly is installed on the suspension in a hanging manner, which can absorb working vibration by shaking, further reducing vibration and noise; the sound-absorbing cotton on the inner wall of the bottom box and the box cover can absorb noise, improving the quiet effect of the control box.

[0013] The third purpose of the invention of the utility model is to provide a noise reduction inflatable bed, including a bed frame, a mattress with an air bag built in, and a control box for supplying air to the air bag, the control box being connected to the air bag through an air pipe, wherein the control box is one of the aforementioned noise reduction control boxes, the control box being externally disposed on the mattress and disposed on the bed frame.

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1-7 As shown, embodiment 1 is an integrated noise reduction air pump assembly, including three air pumps 1 and air boxes 2 and an air path connecting the two. Each air pump 1 is provided with an air outlet nozzle 1-1, and the two sides of the air box 2 are respectively provided with three air inlet connectors 2-1 arranged in a row and an air outlet connector 2-2. All air pumps 1 and air boxes 2 are arranged in a detachable shell 3. The shell 3 in this embodiment is formed by connecting the left and right shells shown in the figure with screws. The three air pumps 1 and an air box are separately installed in the two shells. The air outlet nozzles 1-1 of the three air pumps 1 are matched with the three air inlet connectors 2-1 and sealed and plugged to form an air path. The shell 3 is provided with an opening 3-1 matching the air outlet connector 2-2.

[0027] The noise reduction air pump assembly optimizes the overall structure. All air pumps and air boxes are integrated in a housing 3. The air path between the air pump and the air box eliminates the conventional hose and is replaced by a plug-in connector. The plug-in assembly and subsequent disassembly are very convenient, and there is no need to sort out the coiled hose. The integrated air pump assembly is an independent component that can be prefabricated in advance for mass production, which is convenient for subsequent assembly with other components to make a control box for an inflatable mattress.

[0028] Furthermore, the structure of the air inlet connector 2-1 is also optimized to ensure the effect of sealed docking. The air inlet connector 2-1 includes a first connector tube 2-11 provided on the surface of the air box 2 and connected to the inner cavity, and an elastic sealing sleeve 2-12 sleeved thereon. The sealing sleeve 2-12 is preferably made of elastic silicone material, and has a double-layer structure consisting of an inner tube wall 2-13 and an outer tube wall 2-14. The inner tube wall and the outer tube wall are connected as a whole at the front end of the sealing sleeve 2-12. When in use, the outer tube wall 2-14 is tightly sleeved on the outside of the first connector tube 2-11, and the inner tube wall 2-13 is inserted into the first connector tube 2-11 to form a plug-in channel 4 for docking the air outlet nozzle 1-1. The air outlet nozzle 1-1 is inserted into the plug-in channel 4 and tightly matches the inner tube wall 2-14 to achieve sealed plug-in connection with the air inlet connector 2-1.

[0029] In order to further optimize the compactness of the noise reduction air pump assembly, the first joint tube 2-11 is arranged in a concave hole formed in the surface of the air box 2, and the side walls of the concave hole surround the first joint tube 2-11 to form an annular groove 5 that can accommodate the outer tube wall 2-14. By arranging the first joint tube in the concave surface of the air box, the length occupied by the air nozzle and the air intake joint is shortened.

[0030] Furthermore, a shock-absorbing assembly for shock-absorbing the air pump 1 and the air box 2 is also provided in the housing 3, and the shock-absorbing assembly includes an air pump shock-absorbing sleeve 6 and an air box shock-absorbing sleeve 7, wherein the air pump shock-absorbing sleeve 6 is suspended on the inner wall of the housing 3 and is tightly sleeved outside the air pump 1, and the air box shock-absorbing sleeve 7 is tightly attached to the inner wall of the housing 3 and is tightly sleeved outside the air box 2. When working, the two shock-absorbing sleeves have a shock-absorbing effect on the air pump and the air box respectively, alleviate the vibration generated by the work of the air pump and the air box, and thus reduce noise.

[0031] As shown in the figure, three through holes 6-1 with the same shape as the air pump 1 are arranged on the air pump shock-absorbing sleeve 6 in this embodiment. In this embodiment, the ring bodies at both ends are preferably provided with hanging ears, and two hanging ears 8 with holes are symmetrically arranged on the periphery of each ring body. The inner wall of the shell 3 is provided with a mounting column 3-2 for sleeve-connecting the hanging ears 8; the air box shock-absorbing sleeve 7 is provided with an annular hole 7-2 matching the shape of the air box 2. The specific air pump shock-absorbing sleeve 6 is formed by three ring bodies arranged in a row and the arc edges of two adjacent ring bodies connected in one body. The inner periphery of the ring body surrounds the through hole, and the hanging ears can be folded and retracted along its length direction. The ring body is tightly fitted with the air pump through the inner edge hole, and the arc edge connects all the ring bodies into an integrated structure. The hanging ears suspend the air pump shock-absorbing sleeve and the air pump in the shell; when the air pump generates vibration during operation, the hanging ears and the arc edges can be elastically deformed to absorb and alleviate the vibration generated by the operation of the air pump, and prevent the vibration from spreading outward and affecting other components.

[0032] like Figure 8 As shown, Example 2 is a noise reduction control box, including a matching base box 11 and a box cover 12, an air pump assembly and a controller (not shown in the figure) arranged in the inner cavity of the base box 11, the air pump assembly includes an air pump 1 and an air box 2 and a connecting air circuit, the air pump assembly in this embodiment is the integrated noise reduction air pump assembly described in Example 1, the housing 3 of the controller and the integrated noise reduction air pump assembly is arranged on a suspension 16, the suspension 16 is connected to an elastic hanging rod 13 through a plurality of vibration support feet 14, the hanging rod 13 is fixed in the base box 11, and the hanging rod here is preferably made of spring steel.

[0033] Since the air pump assembly in the control box adopts the integrated noise reduction air pump assembly in Example 1, the control box structure is more compact and more integrated, which is convenient for assembly and subsequent maintenance and replacement. It is not necessary to reconnect the hose ventilation path and arrange the hose routing every time the air pump assembly is replaced, which can effectively save the internal space of the bottom box and create conditions for further reducing and optimizing the volume of the control box; the integrated air pump assembly is suspended in the inner cavity of the bottom box using a suspension with a shock-absorbing effect. The suspension uses shock-absorbing feet to alleviate the working vibration of the air pump assembly and its impact on the bottom box, reduce the noise of the control box, and prevent the vibration of the control box from affecting the use of the mattress. The hanging rod made of elastic spring steel can use its own deformation to further alleviate the vibration generated by the work of the air pump assembly. In addition, in order to further reduce the noise and shock of the control box, the shell 3 is hung on the suspension 16, and the vibration generated by the work of the air pump assembly can be absorbed by shaking and buffering. At the same time, the inner wall of the bottom box 11 and the inner wall of the box cover 12 are both affixed with sound-absorbing cotton for sound insulation and noise reduction.

[0034] like Fig. 9 As shown, Example 3 is a noise reduction inflatable bed, including a bed frame 18, a mattress 19 with an air bag built in, and a control box 17 for supplying air to the air bag. The control box 17 is connected to the air bag through an air pipe 15. The control box 17 of this embodiment is the noise reduction control box described in Example 2. The control box 17 is externally placed on the mattress 19 and is arranged on the bed frame 18. The inflatable bed uses the noise reduction control box of Example 2 to inflate the air bag. When working, the noise is low and the vibration is small, which will not affect the use of the mattress. It has a significant effect on keeping the headrest quiet and improving the sleeping effect.
