Description

Technical Field

[0001] The utility model relates to the technical field of oxygen generators, and particularly relates to a noise-reducing oxygen generator. Background Art

[0002] Oxygen generators have been widely used in people's lives. Structures such as compressors and blowers are usually included in oxygen generators.

[0003] During the use of the oxygen generator, components such as compressors and blowers inside the oxygen generator are prone to vibration during mechanical movement, thus generating mechanical noise that is conducted to the surrounding of the oxygen generator. At the same time, the air flow inside the oxygen generator is also prone to generating noise, affecting the normal life of users. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a noise-reducing oxygen generator, which can play a role in shock absorption and noise reduction for the overall spatial structure inside the oxygen generator.

[0005] To solve the above technical problems, the utility model adopts the following solutions:

[0006] A noise-reducing oxygen generator includes a base. A molecular sieve tower, a compressor, and a blower are provided on the base. An integrated mounting frame is connected to the base. The compressor and the blower are both arranged inside the mounting frame. The molecular sieve tower is embedded on the side wall of the mounting frame. A shock pad is provided between the mounting frame and the molecular sieve tower. The height of the mounting frame is not less than the height of the molecular sieve tower. Its function is that through the setting of the integrated mounting frame, the overall strength of the mounting frame is relatively high, and vibrations are not likely to occur between the structures inside the mounting frame; since the entire side wall of the mounting frame is in contact with the molecular sieve tower, the contact area between the molecular sieve tower and the mounting frame is relatively large. Through the setting of the shock pad, the shock absorption and noise reduction effect of the whole mounting frame can be enhanced.

[0007] Further, the mounting frame includes a top plate, a partition plate, and a bottom plate arranged in sequence from top to bottom. The blower is arranged between the top plate and the partition plate. The compressor is arranged between the partition plate and the bottom plate. An upper shock-absorbing rubber head is provided between the partition plate and the compressor. A lower shock-absorbing rubber head is provided between the compressor and the bottom plate. The upper shock-absorbing rubber head and the lower shock-absorbing rubber head are coaxially arranged. Its function is that through the setting of the upper shock-absorbing rubber head and the lower shock-absorbing rubber head and the design of their spatial relationship, the shock absorption effect of the mounting frame on the compressor can be effectively improved.

[0008] Further, the mounting frame includes two side plates. The top plate, the partition plate, and the bottom plate are all arranged between the two side plates. A molecular sieve tower is coaxially embedded in each side plate respectively. Its function is that through the design of the coaxial spatial relationship between the side plate and the molecular sieve tower, the contact area between the shock pad and the side plate and the molecular sieve tower can be increased as much as possible, thereby improving the shock absorption effect.

[0009] Furthermore, the molecular sieve tower is cylindrical, the side plate is in the shape of a cylindrical surface with an inner diameter not less than the outer diameter of the molecular sieve tower, and at least two shock pads are evenly distributed circumferentially along the axial direction of the side wall of the molecular sieve tower.

[0010] Furthermore, the side plate is provided with an embedding groove for embedding the shock pad. The embedding groove is in the shape of a column whose cross-section is a sector ring extending along the axial direction of the side plate. Its function is that through the setting of the embedding groove, the shock pad can be embedded into the side plate, enhancing the shock absorption effect on the side wall.

[0011] Furthermore, the corners of the embedding groove facing the outside of the mounting frame are rounded. Its function is that through the design of rounding the embedding groove, when the molecular sieve tower presses the shock pad, the shock pad generates a circumferentially diffused deformation, thereby increasing the contact area between the shock pad and the molecular sieve tower, achieving the effect of enhancing the shock absorption and noise reduction.

[0012] Furthermore, the radius of the chamfer on the embedding groove is less than the depth of the embedding groove. Its function is that through the dimension design of the chamfer on the embedding groove, it can prevent the shock pad from falling off the embedding groove along the circumferential direction.

[0013] Furthermore, the base is provided with a front cover, and the rear end face of the front cover fits with the front end faces of the top plate and the partition board. The rear end face of the front cover is the end face of the front cover facing the mounting frame, and the front end face of the partition board is the end face of the partition board facing the front cover. Its function is that through the design of the spatial relationship between the front cover and the partition board, the fixing ability of the front cover to the partition board can be enhanced.

[0014] Furthermore, on the rear end face of the front cover, at the height where the fan is located, there are an air outlet and a wind guide groove arranged in sequence along the horizontal direction. The air outlet is arranged offset from the fan, and the wind guide groove is arranged opposite to the fan. Its function is that through the setting of the spatial relationship between the air outlet and the wind guide groove and the fan, it can prevent the wind blown out by the fan from directly blowing towards the air outlet and easily generating noise.

[0015] Furthermore, on the rear end face of the front cover, at the height where the compressor is located, there is a noise reduction groove for embedding sound-absorbing material. The sound-absorbing material can adopt existing technologies such as glass wool and foam plastic. The cross-section of the noise reduction groove is in the shape of a dovetail groove. Its function is that through the setting of the noise reduction groove and its spatial relationship, sound-absorbing material can be loaded into the noise reduction groove to absorb the noise generated by the compressor towards the front cover, effectively reducing noise.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. Through the setting of the integrated mounting frame, the overall strength of the mounting frame is relatively high, and it is not easy for the structures inside the mounting frame to vibrate; since the entire side wall of the mounting frame is in contact with the molecular sieve tower, the contact area between the molecular sieve tower and the mounting frame is relatively large. Through the setting of the shock pad, the shock absorption and noise reduction effect on the overall mounting frame can be enhanced;

[0018] 2. By setting the spatial relationship between the air outlet, the air guide groove and the fan, it is possible to avoid the wind blown by the fan directly blowing towards the air outlet, which is likely to generate noise.

[0019] 3. By setting the noise reduction groove and its spatial relationship, sound-absorbing materials can be installed in the noise reduction groove to absorb the noise generated by the compressor towards the front cover, effectively reducing noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A noise-reducing oxygen generator, as Figure 1 shown, includes a base 1, on which a molecular sieve tower 2, a compressor 3, and a fan 4 are arranged. An integral mounting bracket 5 is connected to the base 1. The compressor 3 and the fan 4 are both arranged inside the mounting bracket 5. The molecular sieve tower 2 is embedded in the side wall of the mounting bracket 5, and a shock pad 6 is arranged between the mounting bracket 5 and the molecular sieve tower 2. The height of the mounting bracket 5 is not less than the height of the molecular sieve tower 2. Its function is that through the arrangement of the integral mounting bracket 5, the overall strength of the mounting bracket 5 is relatively high, and vibrations are not likely to occur between the structures inside the mounting bracket 5; since the entire side wall of the mounting bracket 5 is in contact with the molecular sieve tower 2, the contact area between the molecular sieve tower 2 and the mounting bracket 5 is relatively large. Through the arrangement of the shock pad 6, the shock absorption and noise reduction effect of the entire mounting bracket 5 can be enhanced.

[0030] Specifically, as Figure 2 shown, the mounting bracket 5 includes a top plate 7, a partition plate 8, and a bottom plate 9 arranged in sequence from top to bottom. The fan 4 is arranged between the top plate 7 and the partition plate 8, the compressor 3 is arranged between the partition plate 8 and the bottom plate 9, an upper shock-absorbing rubber head 10 is arranged between the partition plate 8 and the compressor 3, a lower shock-absorbing rubber head 11 is arranged between the compressor 3 and the bottom plate 9, and the upper shock-absorbing rubber head 10 and the lower shock-absorbing rubber head 11 are coaxially arranged. Its function is that through the arrangement of the upper shock-absorbing rubber head 10 and the lower shock-absorbing rubber head 11 and the design of their spatial relationship, the shock absorption effect of the mounting bracket 5 on the compressor 3 can be effectively improved.

[0031] Specifically, as Figure 2 shown, the mounting bracket 5 includes two side plates 12. The top plate 7, the partition plate 8, and the bottom plate 9 are all arranged between the two side plates 12, and each side plate 12 coaxially embeds a molecular sieve tower 2 respectively. Its function is that through the design of the spatial relationship where the side plates 12 are coaxial with the molecular sieve tower 2, the contact area between the shock pad 6 and the side plates 12 and the molecular sieve tower 2 can be increased as much as possible, thereby improving the shock absorption effect.

[0032] Specifically, as Figure 1 、 Figure 2As shown, the molecular sieve tower 2 is cylindrical, and the side plate 12 is in the shape of a cylindrical surface with an inner diameter not less than the outer diameter of the molecular sieve tower 2. At least two shock pads 6 are evenly distributed circumferentially along the axial direction of the side wall of the molecular sieve tower 2.

[0033] Specifically, as Figure 3 shown, an embedding groove 13 for embedding the shock pad 6 is provided on the side plate 12. The embedding groove 13 is in the shape of a column whose cross-section is a sector ring and extends along the axial direction of the side plate 12. Its function is that through the setting of the embedding groove 13, the shock pad 6 can be embedded into the side plate 12, enhancing the shock absorption effect on the side wall.

[0034] Specifically, as Figure 3 shown, the corners of the embedding groove 13 facing outside the mounting frame 5 are rounded. Its function is that through the design of rounding the embedding groove 13, when the molecular sieve tower 2 presses the shock pad 6, the shock pad 6 generates a circumferentially diffused deformation, thereby increasing the contact area between the shock pad 6 and the molecular sieve tower 2, achieving the effect of enhancing shock absorption and noise reduction.

[0035] Specifically, as Figure 3 shown, the radius of the chamfer on the embedding groove 13 is less than the depth of the embedding groove 13.

[0036] Specifically, as Figure 1 shown, a front cover is provided on the base 1, and the rear end face of the front cover fits with the front end faces of the top plate 7 and the partition plate 8. The rear end face of the front cover is the end face of the front cover facing the mounting frame 5, and the front end face of the partition plate 8 is the end face of the partition plate 8 facing the front cover. Its function is that through the design of the spatial relationship between the front cover and the partition plate 8, the fixing ability of the front cover to the partition plate 8 can be enhanced.

[0037] Specifically, as Figure 4 shown, an air outlet 14 and a wind guide groove 15 are provided on the rear end face of the front cover at the height where the fan 4 is located, arranged horizontally in sequence. The air outlet 14 is arranged in a staggered manner with the fan 4, and the wind guide groove 15 is arranged opposite to the fan 4. Its function is that through the setting of the spatial relationship between the air outlet 14 and the wind guide groove 15 and the fan 4, it can prevent the wind blown out by the fan 4 from directly blowing towards the air outlet 14 and easily generating noise.

[0038] Specifically, as Figure 4 shown, a noise reduction groove 16 for embedding sound-absorbing material is provided on the rear end face of the front cover at the height where the compressor 3 is located. The sound-absorbing material can adopt existing technologies such as glass wool and foam plastics. The cross-section of the noise reduction groove 16 is in the shape of a dovetail groove. Its function is that through the setting of the noise reduction groove 16 and its spatial relationship, sound-absorbing material can be loaded into the noise reduction groove 16 to absorb the noise generated by the compressor 3 towards the front cover, effectively reducing noise.

[0039] The working principle of this embodiment is described as follows: During the operation of the oxygen generator, the vibration generated by the compressor 3 is alleviated by the upper shock-absorbing rubber head 10 and the lower shock-absorbing rubber head 11, reducing the vibration transmitted to the mounting frame 5. The vibration of the mounting frame 5 caused by the fan 4 and the compressor 3 is transmitted to the shock-absorbing pad 6 and alleviated by the shock-absorbing pad 6. At the same time, the airflow noise generated by the fan 4 is reduced by the spatial layout of the air guide groove 15 and the air outlet 14, and the noise generated by the compressor 3 is absorbed by the sound-absorbing material in the noise reduction groove 16.

[0040] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Based on the technical essence of the present invention, any simple modifications, equivalent replacements, and improvements made to the above embodiments within the spirit and principle of the present invention still fall within the protection scope of the technical solution of the present invention.
