[0021] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0022] Please refer to Figures 1 to 5 A suspended silent inflation device includes a housing 1, a mounting bracket 2, an air pump 3, and an elastic element 5. The housing 1 is provided with an air inlet 121 and an air outlet 131. The mounting bracket 2 is fixed inside the housing 1. The mounting bracket 2 is provided with an assembly chamber 21. The air pump 3 is located in the assembly chamber 21, and one end of the air pump 3 is connected to the air outlet 131. The peripheral wall of the air pump 3 is connected to the inner wall of the assembly chamber 21 through the elastic element 5, and the air pump 3 is not in contact with the inner wall of the assembly chamber 21.
[0023] As can be seen from the above description, the beneficial effects of the present invention are as follows: the suspended silent inflation device has a simple and novel structure, which is convenient for production and assembly; by connecting the air pump 3 to the inner wall of the assembly chamber 21 through the elastic element 5, the air pump 3 is suspended in the assembly chamber 21, which can prevent the air pump 3 from vibrating and hitting the mounting bracket 2 when it is working. At the same time, the shock absorption capacity of the elastic element 5 is used to reduce the vibration amplitude of the air pump 3, thereby reducing the noise generated by the air pump 3 when it is working.
[0024] Furthermore, there are multiple elastic elements 5, which are divided into several groups, and at least one group of elastic elements 5 are evenly distributed around the axial direction of the air pump 3.
[0025] As described above, the even distribution of elastic elements 5 around the axial direction of the air pump 3 allows multiple elastic elements 5 to withstand the vibration forces of the air pump 3 in different directions. Specifically, regardless of whether this suspended silent inflation device is in an upright, oblique, or inverted position, the numerous elastic elements 5 can effectively keep the air pump 3 suspended.
[0026] Furthermore, a shock-absorbing ring 6 is provided on the inner peripheral wall of the assembly chamber 21 or on the outer peripheral wall of the air pump 3.
[0027] As described above, the shock absorber ring 6 can prevent the air pump 3 from vibrating too much under its own or external force and impacting the inner wall of the assembly chamber 21.
[0028] Furthermore, the housing 1 includes a soundproof cavity support 11, a mounting housing 12, and a soundproof housing 13. The mounting housing 12 has a mounting cavity 122, and the soundproof housing 13 has a rear cavity 132. The mounting housing 12 and the soundproof housing 13 are fixedly connected. The soundproof cavity support 11 is disposed between the mounting housing 12 and the soundproof housing 13 to separate the mounting cavity 122 and the rear cavity 132. The air inlet 121 communicates with the mounting cavity 122, and the air outlet 131 communicates with the rear cavity 132. The mounting bracket 2 is disposed in the mounting cavity 122, and one end of the air pump 3 is connected to the rear cavity 132.
[0029] As described above, the gas output by the air pump 3 must pass through the rear cavity 132 and the air outlet 131 in sequence. The mounting cavity 122 and the rear cavity 132 can isolate the noise generated by the air pump 3 during operation to a certain extent; at the same time, the rear cavity 132 can provide a certain buffer space for the turbulent airflow output by the air pump 3, so that the airflow that finally passes through the air outlet 131 becomes more stable, thereby reducing the airflow noise generated by this suspended silent inflation device during operation.
[0030] Furthermore, the soundproof cavity support 11 is provided with an air pipe interface 111 that connects to the rear cavity 132, and the air pump 3 is connected to the air pipe interface 111 through an air pipe 7, and the air pipe 7 has a bend.
[0031] As can be seen from the above description, the bend in the trachea 7 can reduce the airflow noise generated when the air pump 3 is working.
[0032] Furthermore, the trachea 7 is made of a flexible material.
[0033] As can be seen from the above description, the use of flexible material to make the air tube 7 can reduce the vibration intensity transmitted to the sound insulation cavity support 11 when the air pump 3 is working, thereby reducing the noise generated by this suspended silent inflation device.
[0034] Furthermore, the soundproof cavity support 11 has a first annular protrusion 112 on one side away from the mounting housing 12, and the soundproof housing 13 has a second annular protrusion 133 corresponding to the first annular protrusion 112. The first annular protrusion 112 and the second annular protrusion 133 form a soundproof cavity 113. One end of the air pump 3 and the air outlet 131 are respectively connected to the two ends of the soundproof cavity 113, and the soundproof cavity 113 is provided with soundproof cotton 8.
[0035] As described above, the gas generated by the air pump 3 needs to pass through the air pipe interface 111, the sound insulation cavity 113 and the air outlet 131 in sequence. The sound insulation cotton 8 in the sound insulation cavity 113 has good sound absorption capacity, which helps to reduce the airflow noise generated when the air pump 3 is working.
[0036] Furthermore, gaps are formed between the sound insulation cotton 8 and the two end walls of the sound insulation cavity 113.
[0037] As can be seen from the above description, creating a gap between the sound insulation cotton 8 and the two end walls of the sound insulation cavity 113 can reduce the impact of airflow obstruction caused by the installation of the sound insulation cotton 8.
[0038] Furthermore, it also includes a sound insulation sheet 9, which is fixed inside the air inlet 121.
[0039] As can be seen from the above description, the sound insulation sheet 9 can reduce the airflow noise generated when air passes through the air intake 121.
[0040] Furthermore, the elastic element 5 is a spring, a sheet, a silicone pad, a silicone tube, or a silicone cap.
[0041] As can be seen from the above description, the specific types and structures of elastic elements 5 are diverse, and can be selected according to different usage conditions and assembly requirements.
[0042] Example 1
[0043] Please refer to Figures 1 to 5 Embodiment 1 of the present invention is: a suspended silent inflation device, which can be widely used to inflate various airbag products, such as inflatable toys, air mattresses, inflatable dolls or balloons.
[0044] This suspended silent inflation device includes a housing 1, a mounting bracket 2, an air pump 3, and an elastic element 5. The housing 1 is provided with an air inlet 121 and an air outlet 131. The mounting bracket 2 is fixed inside the housing 1. The mounting bracket 2 is provided with an assembly chamber 21. The air pump 3 is located in the assembly chamber 21, and one end of the air pump 3 is connected to the air outlet 131. The peripheral wall of the air pump 3 is connected to the inner wall of the assembly chamber 21 through the elastic element 5, and the air pump 3 is not in contact with the inner wall of the assembly chamber 21.
[0045] Specifically, in this embodiment, the suspended silent inflation device also includes a battery 4, which is fixed on the mounting bracket 2 to supply power to the air pump 3; in other embodiments, this charging device can use an external power source to supply power to the air pump 3. The housing 1 has protruding bosses at both ends, with an air inlet 121 and an air outlet 131 respectively located on the bosses. The bosses facilitate connection of this suspended silent inflation device to the inflation interface of an inflatable toy or air mattress. The housing 1 also has a window 10 to allow external control lines to pass through and electrically connect to the air pump 3 in the housing 1, thereby controlling the operating state of the air pump 3.
[0046] In this embodiment, the elastic element 5 is preferably a spring. In other embodiments, the elastic element 5 may be a sheet, a silicone pad, a silicone tube, or a silicone cap. Figure 3 and Figure 4 As shown, there are multiple elastic elements 5, which are divided into several groups, and at least one group of elastic elements 5 are evenly distributed around the axial direction of the air pump 3.
[0047] In this embodiment, there are eight elastic elements 5, divided into two groups. In each group of four elastic elements 5, the central axis of any one elastic element 5 is perpendicular to the central axes of the two adjacent elastic elements 5, and the central axes of the four elastic elements 5 pass through the same intersection point, which is located on the central axis of the air pump 3. When the air pump 3 vibrates and moves in any radial direction during operation, at least one elastic element 5 is compressed and at least one elastic element 5 is stretched. The elastic elements 5 will generate a reverse force on the air pump 3, thereby reducing the vibration intensity of the air pump 3. In other embodiments, the elastic elements 5 can be set as one group, three groups or more; each group of elastic elements 5 can have two, three or more.
[0048] like Figure 4 As shown, a shock-absorbing ring 6 is provided on the inner peripheral wall of the assembly chamber 21 or on the outer peripheral wall of the air pump 3. In this embodiment, the shock-absorbing ring 6 is preferably a cotton ring, and two rings are provided, with the two shock-absorbing rings 6 spaced apart on the outer peripheral wall of the air pump 3. In other embodiments, the shock-absorbing ring 6 can be made of rubber or silicone, and there can be one, three or more rings.
[0049] like Figure 2As shown, the housing 1 includes a soundproof cavity support 11, a mounting housing 12, and a soundproof housing 13. The mounting housing 12 has a mounting cavity 122, and the soundproof housing 13 has a rear cavity 132. The mounting housing 12 is fixedly connected to the soundproof housing 11. The soundproof cavity support 11 is disposed between the mounting housing 12 and the soundproof housing 13 to separate the mounting cavity 122 and the rear cavity 132. The air inlet 121 communicates with the mounting cavity 122, and the air outlet 131 communicates with the rear cavity 132. The mounting bracket 2 is disposed in the mounting cavity 122, and one end of the air pump 3 is connected to the rear cavity 132.
[0050] Specifically, the mounting bracket 2 is fixed on the sound insulation cavity bracket 11; the mounting housing 12 and the sound insulation housing 13 can be connected by snap-fit or adhesive; the inner wall of the mounting housing 12 is provided with a stepped structure, and the sound insulation cavity bracket 11 is located between the stepped structure and the end face of the sound insulation housing 13.
[0051] like Figure 2 and Figure 4 As shown, the soundproof cavity support 11 is provided with an air pipe interface 111 that connects to the rear cavity 132. The air pump 3 is connected to the air pipe interface 111 through an air pipe 7, and the air pipe 7 has a bending area. The air pipe 7 is made of a flexible material. In this embodiment, the air pipe 7 is preferably made of rubber. The bending area of the air pipe 7 can provide a certain margin for the vibration deformation of the air pipe 7, and at the same time extend the total length of the air pipe 7, thereby greatly improving the phenomenon that the vibration generated by the air pump 3 is transmitted to the soundproof cavity support 11 through the air pipe 7.
[0052] like Figure 2 and Figure 5 As shown, the soundproof cavity support 11 has a first annular boss 112 on one side away from the mounting housing 12, and the soundproof housing 13 has a second annular boss 133 corresponding to the first annular boss 112. The first annular boss 112 and the second annular boss 133 form a soundproof cavity 113. One end of the air pump 3 and the air outlet 131 are respectively connected to the two ends of the soundproof cavity 113, and the soundproof cavity 113 is provided with soundproof cotton 8. Specifically, the soundproof cotton 8 is cylindrical. To improve the soundproofing effect of the soundproof cavity 113, the soundproof housing 13 also has a third annular boss 134 on the outer periphery of the second annular boss 133. The first annular boss 112 extends between the second annular boss 133 and the third annular boss 134, and the outer edge of the first annular boss 112 has a chamfered structure to facilitate the assembly of the first annular boss 112.
[0053] like Figure 2 and Figure 5As shown, gaps are formed between the sound insulation cotton 8 and the two end walls of the sound insulation cavity 113. Specifically, the inner side of the first annular boss 112 on the sound insulation cavity support 11 is provided with a limiting protrusion 114 protruding away from the sound insulation cavity support 111, and the sound insulation cotton 8 is clamped between the end face of the limiting protrusion 114 and the second annular boss 133.
[0054] like Figure 2 As shown, this suspended silent inflation device also includes a sound-insulating sheet 9, which is fixed inside the air inlet 121. In this embodiment, the sound-insulating sheet 9 is preferably made of cotton, and is glued to the inside of the air inlet 121 to seal the air inlet 121.
[0055] In summary, the suspended silent inflation device provided by this invention has a simple and novel structure, facilitating production and assembly. By connecting the air pump to the inner wall of the assembly chamber via an elastic element, the air pump is suspended within the assembly chamber, preventing it from vibrating and impacting the mounting bracket during operation. Simultaneously, the shock-absorbing capacity of the elastic element reduces the vibration amplitude of the air pump, thereby reducing noise generated during operation. The addition of a shock-absorbing ring further prevents the air pump from colliding with the mounting bracket. The flexible material of the air pipe reduces the vibration intensity transmitted from the air pump to the soundproof cavity bracket. The soundproof cavity and sound-absorbing cotton reduce the airflow noise generated by the air pump. Gaps are formed between the sound-absorbing cotton and the end walls of the soundproof cavity, which helps to mitigate the airflow obstruction caused by the sound-absorbing cotton. The sound-absorbing cotton also reduces the airflow noise generated by air passing through the air inlet.
[0056] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
