[0002] Ventilators have become an indispensable routine medical device in medical institutions, widely used in various clinical departments, especially emergency and intensive care units. The gas supply device of a ventilator includes a compressed air supply device and an oxygen supply device. The compressed air provided by the compressed air supply device and the oxygen provided by the oxygen supply device are mixed in a certain proportion and then delivered to the breathing mask for the patient's use.

[0003] In the existing technology, the air compressor used in medical ventilators has an unreasonable internal component layout, which leads to insufficient use of internal space, resulting in an excessively large external size of the air compressor, which is not conducive to miniaturization design and has a high production cost. Summary of the Invention

[0005] To address the above problems, the present invention proposes the following technical solution:

Therefore, they should not be construed as limitations on the present invention.

[0031] See Figures 1-5 The present invention provides an air compressor comprising a first mounting bracket 1, a second mounting bracket 10, a filter device 2, a compression pump 3, a copper pipe 4, a pressure reducing valve 5, a pressure display assembly 6, and a drain filter 7. The second mounting bracket 10 is disposed inside the first mounting bracket 1, and the second mounting bracket 10 has a first cavity A inside. The compression pump 3 is disposed in the first cavity A. A second cavity B is formed between the lower end of the second mounting bracket 10 and the inner bottom of the first mounting bracket 1. The copper pipe 4 is installed in the second cavity B. The compression pump 3 and the copper pipe 4 are arranged along a first direction. A third cavity C is formed between one end of the second mounting bracket 10 and the inner wall of the first mounting bracket 1. The first cavity A and the third cavity C are arranged along the second direction. The pressure-sensing component 6 and the drain filter 7 are disposed in the third cavity C and arranged along the third direction. The pressure-reducing valve 5 is disposed on one side of the second mounting bracket 10, and the filter device 2 is disposed on the other side of the second mounting bracket 10 away from the pressure-reducing valve 5. The filter device 2, the compressor pump 3, and the pressure-reducing valve 5 are arranged along the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0032] See Figures 2-3 The filter device 2 is provided with an air inlet pipe 20. The filter device 2 is connected to the compressor pump 3 through a first pipe 200. The compressor pump 3 is connected to the copper pipe 4 through a second pipe 30. The copper pipe 4 is connected to the pressure reducing valve 5 through a third pipe 40. The pressure reducing valve 5 is connected to the drain filter 7 through a fourth pipe 50. The drain filter 7 is provided with an air outlet pipe 70. A branch pipe 500 is connected to the fourth pipe 50. The branch pipe 500 is used to connect to the pressure display component 6.

[0033] Specifically, the compressor pump 3 and the copper pipe 4 are arranged along a first direction, which is a vertical direction, with the compressor pump 3 positioned at the upper end of the copper pipe 4; the first cavity A and the third cavity C are arranged along a second direction, with the pressure-sensing assembly 6 and the drain filter 7 disposed within the third cavity C and arranged along a third direction, which is a front-to-back direction. The arrangement can be either the first cavity A in front and the third cavity C in back, or the third cavity C in front and the first cavity A in back; the third direction is a left-to-right direction, which can be either the pressure-sensing assembly 6 on the left and the drain filter 7 on the right, or the drain filter 7 on the left and the pressure-sensing assembly 6 on the right. Component 6 is on the right; the filter device 2, the compressor pump 3, and the pressure reducing valve 5 are arranged along a third direction. They can be configured such that the filter device 2 is on the left, the compressor pump 3 is in the middle, and the pressure reducing valve 5 is on the right, or the pressure reducing valve 5 is on the left, the compressor pump 3 is in the middle, and the filter device 2 is on the right. Here, the first direction refers to the Z-axis, the second direction refers to the Y-axis, and the third direction refers to the X-axis. By arranging the components within the first mounting frame 1 according to their external dimensions and structural characteristics along three mutually perpendicular directions, the space inside the first mounting frame 1 along the first, second, and third directions can be fully utilized, resulting in a more three-dimensional and compact component layout.

[0034] In this embodiment, during operation, the air intake pipe 20 is used to introduce air into the filter device 2 for filtration, and then the air is conveyed through the first pipe 200 to the compressor pump 3 adjacent to the filter device 2 in a third direction for compression. Afterwards, it is conveyed through the second pipe 30 to the copper pipe 4 adjacent to the filter device 2 in a first direction. The gas compressed by the compressor pump 3 has a certain amount of heat, which is dissipated as it passes through the copper pipe 4. Then, it is conveyed through the third pipe 40 to the pressure reducing valve 5 located above the copper pipe 4 for pressure reduction, and finally, it passes through the fourth pipe 50 to the drain filter 7 and is discharged from the air outlet pipe 70. The second mounting bracket 10 is not... The first mounting bracket is used only for mounting the compressor pump 3 and also cooperates with the first mounting bracket 1 to form a first cavity A, a second cavity B, and a third cavity C. Multiple components inside the air compressor are respectively installed in the three cavities and arranged along the first direction, the second direction, and the third direction. The first direction, the second direction, and the third direction are perpendicular to each other. This structure, by arranging the components inside the first mounting bracket 1 according to their external dimensions and structural features along three mutually perpendicular directions, can make full use of the space inside the first mounting bracket 1 along the first direction, the second direction, and the third direction, making the internal component layout more three-dimensional and compact, and making the external dimensions of the first mounting bracket 1 smaller, which is conducive to miniaturization design and thus reduces production costs.

[0035] See Figure 3 Preferably, the air compressor further includes a first shock-absorbing structure 100, which is disposed at the inner bottom of the first mounting bracket 1, and the second mounting bracket 10 is connected to the upper end of the first shock-absorbing structure 100, so that the second mounting bracket 10 is disposed at a distance from the inner bottom of the first mounting bracket 1, thereby forming the second cavity B between the lower end of the second mounting bracket 10 and the inner bottom of the first mounting bracket 1.

[0036] Specifically, the compression pump 3 is installed inside the first cavity A. In the second direction, the length of the interior of the first cavity A matches the length of the compression pump 3, and in the first direction, the height of the interior of the first cavity A matches the height of the compression pump 3.

[0037] In this embodiment, the first shock-absorbing structure 100 has a shock-absorbing function on the one hand, and on the other hand, it sets the second mounting bracket 10 at a distance from the inner bottom of the first mounting bracket 1, so that the first cavity A and the second cavity B are arranged along the first direction. This facilitates the installation of the components inside the air compressor into the first cavity A and the second cavity B in appropriate positions. The internal component layout is more three-dimensional and compact, making the first mounting bracket 1 smaller in size, which is conducive to miniaturization design.

[0038] See Figure 3 Preferably, the copper tube 4 is arranged in a curved and meandering manner inside the second cavity B.

[0039] Specifically, the cross-section of the copper tube 4 is curved and meandering, or the cross-section of the copper tube 4 is sinusoidal or cosine wave; or the cross-section of the copper tube 4 is triangular wave.

[0040] In this embodiment, the special structure of the copper pipe 4 allows it to occupy less space when laid inside the second cavity B, i.e., the inner bottom of the first mounting bracket 1; on the other hand, it helps to improve heat dissipation efficiency.

[0041] See Figure 3 Preferably, the pressure display assembly 6 includes a pressure gauge 61, an air tank 62, and a pressure sensor 63. The air tank 62 and the drain filter 7 are arranged opposite each other and along a third direction. The pressure gauge 61 is located between the air tank 62 and the drain filter 7, and the pressure sensor 63 is located on one side of the air tank 62.

[0042] See Figure 2 The branch pipe 500 includes a first branch pipe 501, a second branch pipe 502 and a third branch pipe 503. The first branch pipe 501 is used to connect the fourth pipe 50 and the gas storage tank 62. The second branch pipe 502 is used to connect the gas storage tank 62 and the pressure sensor 63. The third branch pipe 503 is used to connect the pressure gauge 61 to the second branch pipe 502.

[0043] Specifically, the lower end of the drain filter 7 has a drain pipe, which is used to filter moisture in the gas and discharge it through the drain pipe; the gas storage tank 62 and the pressure gauge 61 are set to monitor whether the pressure of the gas passing through other components meets the requirements.

[0044] In this embodiment, the gas storage tank 62 and the drain filter 7 are arranged opposite each other and along a third direction. The pressure gauge 61 is located between the gas storage tank 62 and the drain filter 7, and the pressure sensor 63 is located on one side of the gas storage tank 62. The gas storage tank 62, the pressure gauge 61, and the drain filter 7 are arranged sequentially along a third direction. This structure allows the three components to be arranged in a row in the third cavity C, which is beneficial for the integrated installation of the pressure display component 6 and also for making full use of the external space of the first mounting bracket 1, so as to save space and achieve the purpose of miniaturization.

[0045] See Figure 3 Preferably, the first mounting bracket 1 includes a first side plate 11, a second side plate 12, a connecting rod 17, and a base plate 13. The first side plate 11 and the second side plate 12 are both connected to the base plate 13. The first side plate 11 and the second side plate 12 are arranged opposite to each other and are arranged along a third direction. Two connecting rods 17 are connected between the two ends of the first side plate 11 and the second side plate 12.

[0046] Specifically, the first side plate 11, the second side plate 12, and the base plate 13 can be connected by welding, riveting, bolting, snap-fitting, or other methods; the connecting rod 17 is used to strengthen the strength and stability of the first mounting bracket 1. The outer wall of the first side plate 11 is provided with a groove, and the filter device 2 is fixed to the groove. The air intake pipe 20 and the first pipe 200 penetrate the first side plate 11 and extend into the interior of the first mounting bracket 1, which helps prevent the air intake pipe 20 from drawing in external dust and other impurities, thus ensuring that the air drawn in by the air intake pipe 20 is relatively clean.

[0047] In this embodiment, the structure of the first mounting bracket 1 provides a solid carrier for the installation of each component, and by separating each component, it allows each component to be installed in a suitable position, which is conducive to achieving a miniaturized design.

[0048] See Figure 3 and Figure 5 Preferably, the first mounting bracket 1 further includes a connecting plate 14 disposed between the first side plate 11 and the second side plate 12, the connecting plate 14 being located at the end of the compression pump 3 away from the pressure display assembly 6, and the connecting plate 14 having a communication port 15;

[0049] The air compressor also includes a cooling fan 8, which is located at the communication port 15 and is arranged along the third direction with the compression pump 3.

[0050] Specifically, the communication port 15 is disposed on the connecting plate 14, and the cooling fan 8 is bolted to the side of the connecting plate 14 away from the first cavity A. The communication port 15 is slightly larger than the cooling fan 8, which is beneficial for better matching the shape of the cooling fan 8.

[0051] In this embodiment, the cooling fan 8 is configured to cooperate with the copper pipe 4, which exchanges heat to lower the temperature of the gas inside the copper pipe 4 and raise the temperature of the copper pipe 4. The cooling fan 8 helps to enhance the air circulation inside the first mounting bracket 1, thereby helping the copper pipe 4 dissipate heat.

[0052] See Figure 3 Preferably, the base plate 13 is provided with ventilation holes 16, and a plurality of ventilation holes 16 are evenly spaced apart. Along the first direction, the plurality of ventilation holes 16 are located below the copper pipe 4.

[0053] In this embodiment, the ventilation hole 16 is located below the copper pipe 4. On the one hand, this helps to enhance the heat dissipation effect of the copper pipe 4. On the other hand, the arrangement of multiple ventilation holes 16 helps to prevent larger impurities from entering the interior of the first mounting bracket 1 through the ventilation holes 16.

[0054] See Figure 4 Preferably, the air compressor further includes a housing 9 and a base 91. The first mounting bracket 1 is fixedly mounted on the base 91. The housing 9 is used to cover the outside of the first mounting bracket 1, the second mounting bracket 10, the filter device 2, the compression pump 3, the copper pipe 4, the pressure reducing valve 5, the pressure display assembly 6, the drain filter 7, and the cooling fan 8, and the housing 9 is connected to the base 91. The bottom of the base 91 facing the ventilation holes 16 is provided with ventilation openings 92 corresponding to the plurality of ventilation holes 16, and a ventilation cover 93 is provided on the side wall of the housing 9 opposite to the cooling fan 8.

[0055] Specifically, the filter device 2 is installed in the groove, and part of the filter device 2 protrudes from the outside of the first mounting bracket 1. The outer shell 9 is provided with a protruding shell facing the filter device 2 to match the filter device 2.

[0056] In this embodiment, the outer shell 9 is provided to cover the outside of the first mounting frame 1 and each component, which has a protective function for the first mounting frame 1 and each component, and also has the function of preventing dust and impurities from entering the air compressor, and also has a certain aesthetic effect.

[0057] See Figure 5Preferably, the air compressor further includes a limiting member 90, and the outer shell 9 is connected to the first mounting bracket 1 via the limiting member 90. The limiting member 90 includes a limiting block 901, a limiting post 902, a limiting rod 903, and a limiting plate 904 connected in sequence. The limiting block 901, the limiting post 902, and the limiting rod 903 are coaxially arranged. The diameter of the limiting block 901 is larger than the diameter of the limiting post 902, and the diameter of the limiting post 902 is larger than the diameter of the limiting rod 903. The limiting plate 904 has a rectangular cross-section, and the length of the limiting plate 904 is the same as the diameter of the limiting post 902. A connecting hole 94 matching the limiting post 902 is provided on the side wall of the outer shell 9 near the connecting rod 17. A limiting hole 170 is provided on the connecting rod 17, and the shape of the limiting hole 170 matches the shape of the cross-section of the limiting plate 904.

[0058] In this embodiment, during installation, the outer shell 9 is placed over the first mounting bracket 1 and all components, with the connecting hole 94 aligned with the limiting hole 170. The limiting member 90 is inserted into the connecting hole 94, and the limiting plate 904 is inserted into the limiting hole 170, with the side wall of the connecting plate 14 engaged with the limiting rod 903. Then, the limiting block 901 is rotated to rotate the limiting plate 904 and displace it from the limiting hole 170, thereby achieving engagement and fixing the outer shell 9 to the first mounting bracket 1. The cross-sectional shape of the limiting plate 904 can be triangular, rectangular, polygonal, or various non-circular shapes combined therewith, and the limiting hole 170 matches the limiting plate 904.

[0059] See Figure 3 Preferably, the air compressor further includes a second shock-absorbing structure 103, and the second shock-absorbing structure 103 is provided between the two sides of the compression pump 3 and the first side plate 11 and the second side plate 12 respectively along the second direction.

[0060] Specifically, the first damping structure 100 and the second damping structure 103 have the same structure. The first damping structure 100 includes a damping rubber ball 101 and support rods 102 disposed opposite to the damping rubber ball 101. The damping rubber ball 101 is an elliptical sphere with a hollow interior, and four through holes are provided through the side wall of the damping rubber ball 101. The two support rods 102 are respectively disposed at both ends of the long axis of the damping rubber ball 101.

[0061] In this embodiment, the second shock-absorbing structure 103 has a shock-absorbing effect, which helps to prevent the compression pump 3 from vibrating excessively during operation.

[0062] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
