Description

Technical Field

[0001] The utility model relates to the technical field of portable oxygen generators, in particular to a shock-absorbing ball for an air compressor of a portable oxygen generator. Background Art

[0002] At present, shock-absorbing pads are important components of portable oxygen concentrators. Since the air compressor in the portable oxygen concentrator compresses the air through piston movement, the piston rod moves linearly to compress the air. During this process, the body of the machine will vibrate. The shock-absorbing pads can reduce the vibration generated by the air compressor when it is working, reduce noise, and improve the overall experience of users when using it. It can also play a role in auxiliary fixation.

[0003] However, the inventors found in actual applications that the existing shock-absorbing pads are mostly cylindrical structures, and the shock-absorbing effect is not obvious enough, and the problem of excessive shaking amplitude cannot be solved. Therefore, we propose a shock-absorbing ball for a portable oxygen concentrator air compressor. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0005] Specifically, the technical problem to be solved by the present invention is to provide a shock-absorbing ball for a portable oxygen concentrator air compressor to solve the technical problem that the existing shock-absorbing pads are mostly cylindrical structures, the shock-absorbing effect is not obvious, and the vibration amplitude is too large.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A shock-absorbing ball for a portable oxygen concentrator air compressor comprises: a base;

[0008] a portable oxygen concentrator, the portable oxygen concentrator being arranged on the base;

[0009] an air compressor, the air compressor being arranged in the portable oxygen concentrator;

[0010] A shock-absorbing ball is arranged on the air compressor and on the base.

[0011] As an improved technical solution, an open waist-shaped slot is provided inside the support leg of the air compressor, and the inner cavity of the open waist-shaped slot is movably connected to the shock-absorbing ball.

[0012] As an improved technical solution, the shock-absorbing ball includes an upper component, which is movably connected to the inner cavity of the open waist-shaped slot. A middle component is provided on the upper component, and a lower component is provided at one end of the middle component away from the upper component. The outer surface of the lower component is fixedly connected to the interior of the base.

[0013] As an improved technical solution, the outer surface diameter of the recess of the upper component is adapted to the inner cavity width of the open waist-shaped slot.

[0014] As an improved technical solution, the middle component is an arc-shaped sphere.

[0015] As an improved technical solution, the connection between the lower component and the middle component is in a concave ring shape, and the diameter of the top outer surface of the remaining part is larger than the diameter of the bottom outer surface.

[0016] As an improved technical solution, a fixing groove is opened inside the top of the base, and there are four fixing grooves. The inner cavity of the fixing groove is fixedly connected to the outer surface of the lower component, and the shape and size of the inner cavity of the fixing groove are compatible with the shape and size of the outer surface of the lower component.

[0017] After adopting the above technical solution, the beneficial effects of the utility model are:

[0018] 1. In the present invention, when the air compressor in the portable oxygen concentrator generates vibration during operation, the air compressor will generate corresponding displacement. The shock-absorbing ball serves as an elastic element connecting the base and the air compressor to withstand this displacement and convert it into elastic deformation. The elastic deformation will generate an upward rebound force opposite to the displacement and a damping force opposite to the vibration direction. Under the joint action of these two forces, the vibration generated by the mechanical movement can be offset and eliminated to enhance the buffering function and improve the stability. At the same time, the vibration amplitude of the entire air compressor can be reduced, thereby reducing the vibration amplitude of the entire air compressor and improving the overall stability of the air compressor, thereby ensuring the working stability of the portable oxygen concentrator and improving the overall experience of the user during actual use.

[0019] 2. The utility model fixes the shock-absorbing ball on the base, at this time the lower part of the shock-absorbing ball is fixed in the fixing groove, and then the air compressor in the portable oxygen concentrator is fixed on the shock-absorbing ball, at this time the upper part of the shock-absorbing ball is fixed on the waist-shaped slot opened at the support foot of the air compressor, so as to realize fixing the air compressor in the portable oxygen concentrator on the base through the shock-absorbing ball, thereby facilitating fixing the air compressor in the portable oxygen concentrator on the base through the shock-absorbing ball, and the operation is simple and quick.

In application, the air compressor 3 is fixed on the shock-absorbing ball 4, and the shock-absorbing ball 4 is fixed on the open waist-shaped slot 31 at the support leg on the air compressor 3, so as to fix the air compressor 3 on the shock-absorbing ball 4, thereby facilitating the fixing of the air compressor 3 on the shock-absorbing ball 4, and the operation is simple and quick.

[0036] Reference Figure 4 The shock-absorbing ball 4 includes an upper component 41, which is movably connected to the inner cavity of the open waist-shaped slot 31. A middle component 42 is provided on the upper component 41, and a lower component 43 is provided at one end of the middle component 42 away from the upper component 41. The outer surface of the lower component 43 is fixedly connected to the interior of the base 1.

[0038] The middle part 42 is in the shape of a curved ball.

[0039] The connection between the lower component 43 and the middle component 42 is in a concave ring shape, and the outer surface diameter of the top end of the remaining part is larger than the outer surface diameter of the bottom end. In application, when the air compressor 3 in the portable oxygen concentrator 2 generates vibration during operation, the air compressor 3 will generate corresponding displacement. The shock-absorbing ball 4 serves as an elastic element connecting the base 1 and the air compressor 3 to withstand this displacement and convert it into elastic deformation. The elastic deformation will generate an upward rebound force opposite to the displacement and a damping force opposite to the vibration direction. Under the joint action of these two forces, the vibration generated by the mechanical movement can be offset and eliminated to enhance the buffering function and improve stability.

[0040] Reference Figure 2 and Figure 3 A fixing groove 11 is opened inside the top of the base 1, and there are four fixing grooves 11. The inner cavity of the fixing groove 11 is fixedly connected to the outer surface of the lower component 43. The shape and size of the inner cavity of the fixing groove 11 are adapted to the shape and size of the outer surface of the lower component 43. In application, by fixing the shock-absorbing ball 4 on the base 1, the lower component 43 of the shock-absorbing ball 4 is fixed in the fixing groove 11 to achieve the fixation of the shock-absorbing ball 4 on the base 1, thereby facilitating the fixing of the shock-absorbing ball 4 on the base 1, and the operation is simple and quick.

[0041] In actual use, the shock-absorbing ball 4 is fixed to the base 1, and the lower part 43 of the shock-absorbing ball 4 is fixed in the fixing groove 11. Then, the air compressor 3 in the portable oxygen concentrator 2 is fixed to the shock-absorbing ball 4. At this time, the upper part 41 on the shock-absorbing ball 4 is fixed to the waist-shaped card slot 31 at the support foot of the air compressor 3, so that the air compressor 3 in the portable oxygen concentrator 2 is fixed to the base 1 through the shock-absorbing ball 4. This makes it convenient to fix the air compressor 3 in the portable oxygen concentrator 2 to the base 1 through the shock-absorbing ball 4, and the operation is simple and quick.

[0042] When the air compressor 3 in the portable oxygen concentrator 2 generates vibration during operation, the air compressor 3 will generate corresponding displacement. The shock-absorbing ball 4 serves as an elastic element connecting the base 1 and the air compressor 3 to withstand this displacement and convert it into elastic deformation. The elastic deformation will generate an upward rebound force opposite to the displacement, and a damping force opposite to the vibration direction. Under the joint action of these two forces, the vibration generated by the mechanical movement can be offset and eliminated to enhance the buffering function and improve stability. At the same time, the vibration amplitude of the air compressor 3 can be reduced, thereby reducing the vibration amplitude of the air compressor 3 and improving the overall stability of the air compressor 3, thereby ensuring the working stability of the portable oxygen concentrator 2 and improving the overall experience of the user during actual use. This device can not only reduce the vibration amplitude of the air compressor 3, but also improve the overall stability of the air compressor 3.
