Technical Field
[0001] The utility model belongs to the technical field of compressors, and particularly relates to a pump structure with an exhaust passage. Background Art
[0002] With the acceleration of the urbanization process and the increase in industrial activities, the problem of noise pollution has become increasingly serious, which not only affects people's rest and sleep, but also may pose a potential threat to physical and mental health. Therefore, the research and application of noise improvement technologies have important practical significance.
[0003] Nowadays, as the temperature of the earth's environment is getting higher and higher, almost every household installs air conditioners to relieve the boredom brought by hot air. During the use of air conditioners, the noise mainly comes from the compressors.
[0004] When the compressor is running, valve plate flapping sounds will be generated during the opening and closing of the valve plate on the support. The existing noise reduction method is to add a noise reduction cover on the support, so that the compressed gas in the compressor passes through the support and then directly discharges upward through the noise reduction cover. In practical applications, it is found that the noise reduction effect of this method is not good and cannot better improve the auditory sense. Content of the Utility Model
[0005] In order to solve the deficiencies of the above-mentioned prior art, the utility model provides a pump structure with an exhaust passage, which realizes the purpose of changing the exhaust position, performing re-noise reduction processing on the compressed gas, and effectively improving the auditory sense.
[0006] The technical purpose to be achieved by the utility model is realized through the following technical solutions:
[0007] The utility model provides a pump structure with an exhaust passage, and the pump structure includes a support, a first noise reduction cover, a cylinder block, and a second noise reduction cover;
[0008] The support has a first surface and a second surface arranged opposite to each other, and an exhaust hole penetrating through the first surface and the second surface is formed on the support. The first noise reduction cover is connected to the first surface and communicated with the exhaust hole;
[0009] The cylinder block has a first end face and a second end face arranged opposite to each other. The first end face is connected to the second surface, and the second noise reduction cover is connected to the outer peripheral surface of the cylinder block;
[0010] An exhaust passage is formed between the support and the cylinder block, and the exhaust passage communicates the first noise reduction cover and the second noise reduction cover.
[0011] In some implementation manners, the exhaust passage includes a first passage portion and a second passage portion that are communicated with each other;
[0012] The first channel portion penetrates through the first surface and the second surface, and the second channel portion penetrates through the first end face and the outer peripheral surface of the cylinder block, achieving the effect that the exhaust channel communicates with the first muffler cover and the second muffler cover.
[0013] In some implementation manners, the second channel portion includes a vertically extending section and a horizontally extending section that are in communication with each other;
[0014] The vertically extending section extends from the first end face towards the second end face and does not penetrate through the second end face;
[0015] The horizontally extending section extends from the outer peripheral surface of the cylinder block towards the inner peripheral surface of the cylinder block and does not penetrate through the inner peripheral surface of the cylinder block, achieving the effect of communicating with the second muffler cover and at the same time achieving the effect of lateral exhaust.
[0016] In some implementation manners, the number of the exhaust channels is two, and the two exhaust channels are respectively located on both sides of the exhaust hole, so that after the compressed gas is refracted and silenced by the first muffler cover, it then enters the second muffler cover through the two exhaust channels in a dispersed manner, improving the noise reduction effect.
[0017] In some implementation manners, the number of the second muffler covers is two, and the two second muffler covers are respectively in communication with the two exhaust channels, expanding the silencing space and further improving the silencing effect.
[0018] In some implementation manners, the first muffler cover includes a first panel and a first cover body that protrudes outward from the middle of the first panel;
[0019] The first panel is connected to the first surface, so that a closed cavity is formed inside the first cover body;
[0020] The second muffler cover is provided with an exhaust port for discharging gas, changing the exhaust position, thereby improving the gas eddy current sound and further improving the ear feeling.
[0021] In some implementation manners, the second muffler cover includes a second panel and a second cover body that protrudes outward from the middle of the second panel;
[0022] The second panel is connected to the outer peripheral surface of the cylinder block, and the exhaust port is located on the second cover body. The connection relationship between the second muffler cover and the cylinder block is established through the second panel, and the compressed gas after refraction and silencing is discharged through the exhaust port.
[0023] In some implementation manners, the exhaust port is located on a surface of the second cover body that is away from the second panel, realizing the lateral discharge of the compressed gas, and the rotor counterweight can be avoided during the exhaust process, improving the gas eddy current sound and the ear feeling.
[0024] In some implementations, connection holes are formed on the second panel for positioning and connecting with the outer peripheral surface of the cylinder block, facilitating the alignment and assembly of the second sound muffler with the cylinder block and improving the positioning accuracy and convenience of assembly.
[0025] In some implementations, in the axial direction, the height of the second sound muffler is less than that of the cylinder block, avoiding increasing the original height of the pump structure and adapting to the assembly requirements of a conventional compressor structure.
[0026] In summary, the present utility model has at least the following advantages:
[0027] A pump structure with an exhaust passage provided by the present utility model has an exhaust passage formed between the support and the cylinder block, replacing the way in a traditional compressor where compressed gas directly discharges upward after passing through the sound muffler from the support. This enables the compressed gas to enter the second sound muffler through the exhaust passage after being refracted and silenced by the first sound muffler, changing the exhaust position, increasing the sound silencing space, and performing further noise reduction processing on the compressed gas to effectively improve the auditory sensation. Moreover, by providing a discharge port for gas discharge on the second sound muffler, the rotor counterweight can be avoided during the exhaust process, improving the gas eddy noise and further improving the auditory sensation.

[0040] To make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.
[0041] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
[0042] Embodiment 1:
[0043] Please refer to Figures 1 - 5 , a pump structure with an exhaust passage, the pump structure includes a support 100, a first soundproof cover 200, a cylinder block 300 and a second soundproof cover 400.
[0044] Refer to Figure 2 and Figure 3 , the support 100 has a first surface 110 and a second surface 120 arranged opposite to each other. For example, the support 100 is presented as a circular base structure, usually used for the limit of the rotating shaft, and a shaft sleeve for the rotating shaft to pass through extends outward at the middle position of its first surface 110.
[0045] An exhaust hole 130 is opened on the support 100 through the first surface 110 and the second surface 120. The first soundproof cover 200 is connected to the first surface 110, and the first soundproof cover 200 is communicated with the exhaust hole 130.
[0046] The exhaust hole 130 is used for discharging compressed gas. After the compressed gas is discharged through the exhaust hole 130, it enters the inside of the first silencing cover 200 for refraction silencing. Understandably, the first silencing cover 200 is provided with a through hole for the shaft sleeve to pass through, and the outer periphery of the shaft sleeve is hermetically connected to the edge of the through hole to prevent the compressed gas from escaping through the connection between the shaft sleeve and the through hole, affecting the silencing effect or causing an impact on other components.
[0047] See Figure 4 , the cylinder block 300 has a first end face 310 and a second end face 320 arranged opposite to each other. The first end face 310 is connected to the second surface 120, and the second silencing cover 400 is connected to the outer peripheral surface of the cylinder block 300. That is, the second silencing cover 400 is connected to the outer peripheral surface of the cylinder block 300 in a laterally installed manner.
[0048] See Figure 5 , an exhaust passage 500 is provided between the support 100 and the cylinder block 300, and the exhaust passage 500 communicates with the first silencing cover 200 and the second silencing cover 400.
[0049] As can be seen from the content of the background art, during the operation of the compressor, a valve flap flapping sound will be generated during the opening and closing process of the valve flap. This noise is the main noise source of the compressor. In terms of the specific structure, an installation groove for installing the valve flap is formed on the first surface 110 of the support 100, and the exhaust hole 130 is opened at the bottom of the installation groove, that is, it penetrates the first surface 110 and the second surface 120. One end of the valve flap is fixedly installed in the installation groove, and the other end of the valve flap movably covers the exhaust hole 130. When compressed gas is discharged through the exhaust hole 130, an impact force will be generated on the valve flap, causing the valve flap to lift away from the exhaust hole 130. When there is no compressed gas discharged, the valve flap returns to cover the exhaust hole 130 under the action of its own gravity or its own plasticity, thereby generating a flapping sound.
[0050] To address the noise problem caused by the flapping sound, in this embodiment, the first silencing cover 200 is connected to the first surface 110 of the support 100, the second silencing cover 400 is connected to the outer peripheral surface of the cylinder block 300, and the exhaust hole 130 is communicated with the first silencing cover 200, and the exhaust passage communicates with the first silencing cover 200 and the second silencing cover 400. In this way, when the compressed gas is discharged through the exhaust hole 130, it first enters the inside of the first silencing cover 200 for refraction silencing, and then enters the inside of the second silencing cover 400 through the exhaust passage for secondary refraction silencing. Compared with the traditional method of only setting a silencing cover on the support 100, this embodiment changes the exhaust position, expands the silencing space, reduces the noise transmission, and achieves the effect of reducing the valve flap flapping sound and effectively improving the ear feeling.
[0051] In some embodiments, the exhaust passage includes a first passage portion 510 and a second passage portion 520 that are connected and communicate with each other; the first passage portion 510 penetrates through the first surface 110 and the second surface 120, and the second passage portion 520 penetrates through the first end face 310 and the outer peripheral surface of the cylinder block 300, achieving the effect of connecting the exhaust passage with the first muffler 200 and the second muffler 400.
[0052] It can be understood that one end of the first passage portion 510 communicates with the first muffler 200, the other end of the first passage portion 510 communicates with the second passage portion 520, and the other end of the second passage portion 520 communicates with the second muffler 400. Here, the first passage portion 510 can be in a vertical passage state, that is, the openings formed on the first surface 110 and the second surface 120 of the first passage portion 510 are in an aligned state. Of course, in order to increase the sound absorption path, the first passage portion 510 can also be in an inclined or curved passage state, that is, the openings formed on the first surface 110 and the second surface 120 of the first passage portion 510 are in a non-aligned state.
[0053] It should be noted that in this embodiment, there is no specific limitation on the presentation state of the first passage portion 510, which can be adjusted according to actual needs. In one example, for the convenience of processing, the first passage portion 510 is in a vertical passage state.
[0054] Furthermore, the second passage portion 520 includes a vertical section 521 and a horizontal section 522 that are connected and communicate with each other; the vertical section 521 extends from the first end face 310 towards the second end face 320 and does not penetrate through the second end face 320; the horizontal section 522 extends from the outer peripheral surface of the cylinder block 300 towards the inner peripheral surface of the cylinder block 300 and does not penetrate through the inner peripheral surface of the cylinder block 300, achieving the effect of communicating with the second muffler 400 and at the same time achieving the effect of lateral exhaust.
[0055] As is known, the second muffler 400 is connected to the outer peripheral surface of the cylinder block 300. To avoid the influence of compressed gas on the inside of the cylinder block 300 and ensure the communication relationship between the second passage portion 520 and the second muffler 400, combined with the structure of the traditional cylinder block 300, the vertical section 521 and the horizontal section 522 intersect between the first end face 310 and the outer peripheral surface of the cylinder block 300.
[0056] In the pump structure with an exhaust passage provided in this embodiment, an exhaust passage is provided between the support 100 and the cylinder block 300, replacing the way that compressed gas in the traditional compressor directly discharges upward after passing through the muffler from the support 100. The compressed gas is refracted and silenced by the first muffler 200 and then enters the second muffler 400 through the exhaust passage, changing the exhaust position, increasing the sound absorption space, and performing re-noise reduction processing on the compressed gas, achieving the purpose of effectively improving the ear feeling.
[0057] Example 2:
[0058] The difference between this embodiment and Embodiment 1 is that in this embodiment, further structural optimization is performed on the pump structure of the present utility model. Please refer to Figure 6 .
[0059] In this embodiment, the number of exhaust channels is two, and the two exhaust channels are respectively located on both sides of the exhaust hole 130. After the compressed gas is refracted and silenced by the first silencing cover 200, it then enters the second silencing cover 400 through the two exhaust channels in a dispersed manner, improving the noise reduction effect.
[0060] Furthermore, the number of the second silencing covers 400 is two, and the two second silencing covers 400 are respectively communicated with the two exhaust channels, expanding the silencing space and further improving the silencing effect.
[0061] Since the two exhaust channels are respectively located on both sides of the exhaust hole 130, in order to perform a better refraction and silencing effect on the compressed gas discharged from the two exhaust channels, correspondingly, two second silencing covers 400 are connected to the outer peripheral surface of the cylinder block 300, and one second silencing cover 400 is communicated with one exhaust channel.
[0062] It should be noted that in this embodiment, there is no specific limitation on the number of the exhaust channels and the second silencing covers 400, and it can also be three or four, etc. Similarly, there is no limitation on the specific distribution position of the exhaust channels and the corresponding relationship with the second silencing covers 400, and it can be adjusted according to actual needs. For example, in one example, the number of the exhaust channels is three, one of the exhaust channels is located on one side of the exhaust hole 130, and the other two exhaust channels are located on the other side of the exhaust hole 130. The number of the second silencing covers 400 is two, one of the second silencing covers 400 is communicated with one exhaust channel, and the other second silencing cover 400 is communicated with the two exhaust channels located on the same side.
[0063] A pump structure with exhaust channels provided in this embodiment further improves the silencing effect through the optimized design of the number of the exhaust channels and the second silencing covers 400.
[0064] Example 3:
[0065] The difference between this embodiment and Embodiment 1 is that in this embodiment, further structural optimization is performed on the pump structure of the present utility model. Please refer to Figure 7 and Figure 8 .
[0066] In this embodiment, the first sound insulation cover 200 includes a first panel 210 and a first cover body 220 that bulges outward from the middle of the first panel 210; the first panel 210 is connected to the first surface 110, so that a closed cavity is formed inside the first cover body 220, and an exhaust port 410 for gas discharge is provided on the second sound insulation cover 400.
[0067] It can be understood that after the compressed gas enters the inside of the first cover body 220 through the exhaust hole 130, it is refracted and silenced by the first cover body 220, and then enters the inside of the second sound insulation cover 400 through the exhaust passage for refraction and silencing. The closed cavity formed inside the first cover body 220 here is mainly to change the exhaust position, so that the compressed gas cannot be discharged to the outside through the first cover body 220, replacing the way that the compressed gas in the traditional compressor directly discharges upward after passing through the sound insulation cover by the support 100, thereby improving the gas eddy current sound and further improving the ear feeling.
[0068] In some embodiments, the second sound insulation cover 400 includes a second panel 420 and a second cover body 430 that bulges outward from the middle of the second panel 420; the second panel 420 is connected to the outer peripheral surface of the cylinder block 300, and the exhaust port is located on the second cover body 430. The connection relationship between the second sound insulation cover 400 and the cylinder block 300 is established through the second panel 420, and the compressed gas after refraction and silencing is discharged through the exhaust port 410.
[0069] Furthermore, the exhaust port 410 is located on the side of the second cover body 430 away from the second panel 420, realizing the lateral discharge of the compressed gas, and the rotor counterweight can be avoided during the exhaust process, improving the gas eddy current sound and the ear feeling.
[0070] In some embodiments, connection holes 440 for positioning and connecting with the outer peripheral surface of the cylinder block 300 are provided on the second panel 420, which is convenient for aligning and assembling the second sound insulation cover 400 with the cylinder block 300, and improving the positioning accuracy and convenience of the assembly.
[0071] For example, the number of the connection holes 440 is two, which are respectively located on the opposite sides of the second panel 420. After the threaded ends of the bolts pass through the connection holes 440, they are locked on the cylinder block 300 to perform alignment connection on the second sound insulation cover 400, improving the accuracy and convenience of the assembly.
[0072] In some embodiments, in the axial direction, the height of the second sound insulation cover 400 is less than the height of the cylinder block 300. This kind of height relationship limitation will not increase the original height of the pump structure on the one hand, which is convenient for adapting to the assembly of existing products. On the other hand, it can also compress the height of the traditional sound insulation cover. For example, the height of the first sound insulation cover 200 is less than the height of the traditional sound insulation cover arranged on the support 100, thereby reducing the rotor hot sleeve depth and realizing the flat design of the compressor.
[0073] A pumping structure with an exhaust passage provided in this embodiment has an exhaust passage opened between the support and the cylinder block, replacing the way in which compressed gas in a traditional compressor directly discharges upward after passing through the muffler cover from the support. This enables the compressed gas to enter the second muffler cover through the exhaust passage after being refracted and silenced by the first muffler cover, changing the exhaust position, increasing the silencing space, performing further noise reduction processing on the compressed gas, and achieving the purpose of effectively improving the ear feeling. Moreover, by providing a discharge port for gas discharge on the second muffler cover, the rotor counterweight can be avoided during the exhaust process, improving the gas eddy current sound and further improving the ear feeling.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0076] In addition, terms such as "horizontal", "vertical", "hanging" do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined.

Therefore, all such substitutions, improvements and variations are included within the spirit and scope of the appended claims.
