Referring to fig. 1-8, the embodiment discloses an exhaust structure, which includes a body 1 and a valve plate 2, wherein the body 1 is provided with an exhaust hole 3. The body 1 is also rotatably provided with a rotating part which is positioned at the exhaust side of the exhaust hole 3. Valve block 2 sets up on the rotation portion, and valve block 2 is equipped with a plurality ofly, and each valve block 2 sets up in the circumferential direction of rotation portion. The valve plate 2 comprises a first section 5 connected with the rotating part and a second section 4 used for covering the exhaust hole 3, and the valve plate 2 can be elastically deformed to enable the second section 4 to be close to or far away from the first section 5 so as to open or close the exhaust hole 3.

When the second section 4 shields the exhaust hole 3, a closed space is formed at the air inlet side of the exhaust hole 3, so that the refrigerant in the cylinder is closed, and the refrigerant is compressed in the cylinder. When the pressure of compressed air reaches a certain value, the compressed high-pressure refrigerant air can form an upward impact force, and the second section 4 is warped under the action of the impact force to deform, so that the second section 4 moves towards the direction close to the first section 5, and the exhaust hole 3 is opened. The refrigerant air discharged from the discharge hole 3 can be blown to the first section 5 and move the first section 5, and the valve sheet 2 is integrally rotated under the action of the rotating portion. The valve plate 2 plays a role in guiding the refrigerant while rotating. Moreover, the baffle plate in the prior art is not arranged above the second section 4, so that the problem that the valve plate 2 is upwardly tilted by the impact force of the refrigerant and then collides with the baffle plate to generate noise is solved.

Further, in the circumferential direction around the rotation axis of the rotating portion, the first section 5 and the second section 4 of any one of the valve sheets 2 are both disposed in the same direction. Under operating condition, the high pressure refrigerant probably strikes second section 4 or the high pressure refrigerant lasts and assaults second section 4 at the interval, thereby guarantees the continuation rotation after the valve block 2 atress through all setting up first section 5 and the second section 4 with arbitrary valve block 2 along same direction on the circumferential direction of rotation portion, guarantees the stability of valve block 2 water conservancy diversion effect.

After the valve plates 2 are driven by a refrigerant to rotate through the arrangement of the valve plates 2, when the valve plates 2 stop rotating, the second sections 4 of the valve plates 2 can still cover the exhaust holes 3; the periodic stable use of the device is ensured. Simultaneously, through the setting of a plurality of valve blocks 2, the periodic of exhaust hole 3 is opened can be probabilistic make the refrigerant impact different valve blocks 2, and then the refrigerant frequently strikes same valve block 2 when the periodic of having avoided exhaust hole 3 among the prior art is opened to the most probable to each valve block 2 balanced atress of assurance to the at utmost. Through the even atress of a plurality of valve blocks 2, solved among the prior art because frequent and single impact force of being cold-fed for valve block 2 frequently deforms and causes valve block 2 wearing and tearing, cracked possibility, extension valve block 2's life.

The valve plates 2 are arranged in the circumferential direction of the body 1, so that the layout of the valve plates 2 on the body 1 is more attractive. Meanwhile, in order to ensure that the exhaust hole 3 is opened to a closed state, the second section 4 of one valve plate 2 completely covers the exhaust hole 3, so that the effect of closing the exhaust hole 3 is realized. So that one side of the gas discharge hole 3 can perform a function of compressing gas.

Alternatively, for convenience of processing, the gap between two adjacent second segments 4 is not more than 50 μm. Through adjusting the distance between two adjacent valve blocks 2 to the minimum for exhaust structure can guarantee in the course of the work that valve block 2 stops after rotating, and arbitrary second section 4 can cover exhaust hole 3 completely, guarantees the normal work of the side of admitting air in exhaust hole 3. At the same time, a gap value of not more than 50 μm makes the distance between two adjacent second segments 4 small and facilitates installation and processing. When the valve plate 2 rotates to stop, if the exhaust hole 3 is just positioned at the gap between two adjacent second sections 4, the air leakage efficiency is low because the gap is small and the influence on the compression of the air inlet side of the exhaust hole 3 is small. At the same time, the air discharged from the discharge hole 3 is intercepted by the first segment 5 and drives the first segment 5 to rotate by a small amplitude, so that the valve plate 2 rotates and completely covers the discharge hole 3. Alternatively, the smaller the gap between two adjacent second segments 4, the better, in view of the actual operation and the compression effect in the inlet side of the outlet opening 3.

Under the condition that the exhaust hole 3 is in a closed state, the exhaust hole 3 is positioned in the middle of the second section 4 of any valve plate 2, and the state is an ideal state. However, due to the irregularity of the acting force of the rotation of the valve plate 2 caused by the refrigerant impact, the actual exhaust impact of the exhaust hole 3 and the stress point of the second section 4 of the valve plate 2 cannot be estimated. Therefore, the distance between two adjacent valve plates 2 should be smaller, so that the valve plates 2 are closely matched in clearance, and no matter what point the second section 4 of the valve plate 2 is acted by the exhaust impact of the exhaust hole 3, the valve plates 2 are matched with each other, so that the high-pressure refrigerant gas can be stably discharged.

Further, first section 5 is arc platelike structure, can play the effect of temporary storage and promotion to the refrigerant that blows to first section 5 through curved structure to blow continuously to first section 5 under the effect of refrigerant, the refrigerant makes first section 5 continuously rotate, still can drive first section 5 upward air motion of rotation side when first section 5 rotates, plays better drainage effect to high-pressure draught in the cylinder.

Optionally, one side of the first section 5 in the direction of blowing the refrigerant is concave, the refrigerant can intensively enter the concave part of the first section 5 when blowing the refrigerant to the first section 5, the concave part of the first section 5 can also play a certain storage role on the refrigerant, and the refrigerant drives the first section 5 to rotate under the action of the motion inertia of the refrigerant. When the exhaust hole 3 is in an open state, the impact force of the high-pressure refrigerant gas is upward, and the second section 4 is bent and deformed under the action of the refrigerant, so that a force releasing process can be performed on the high-pressure refrigerant gas. The first section 5 rotates under the action of the refrigerant, and the rotating power of the valve plate 2 can form centripetal force for flow guiding, so that the flow guiding effect is achieved on the refrigerant.

Further, the first segment 5 may further include a third portion and a fourth portion connected in series. One end of the third part is fixedly connected with the second section 4, and the fourth part is arranged at one end of the third part far away from the second section 4.

Optionally, the third portion is an arc-shaped plate-shaped structure, and the fourth portion is a flat plate-shaped structure. The setting through arc platelike structure can play the effect of water conservancy diversion to the refrigerant, and the flat structure setting of fourth part can provide the biggest deformation space for second section 4, avoids 4 deformation in-process of second section to strike with first section 5 to the problem of noise production.

Further, the body 1 comprises a base 6 and a neck seat 7, the base 6 is arranged in a cylindrical structure, and the exhaust holes 3 are arranged on the base 6; the neck seat 7 is vertically and fixedly arranged on the central axis of the base 6.

Specifically, a boss 8 is arranged on the base 6, and the exhaust hole 3 is arranged on the boss 8. In order to ensure the sealing effect of the valve plate 2 on the exhaust hole 3, the lower surface of the second section 4 is flush with the upper surface of the boss 8. At this moment, a height difference is formed between the valve plate 2 and the base 6, and the valve plate 2 reduces impact force and friction force between the valve plate 2 and the base 6 in the rotating process through the height difference. Meanwhile, in the process of the up-and-down swinging of the valve plate 2, the height difference is formed, the up-and-down swinging amplitude of the valve plate 2 is increased, the stroke of the valve plate 2 moving downwards is increased, the possibility of impact between the valve plate 2 and the base 6 is further reduced, and the damage to the valve plate 2 in the working process is reduced.

Optionally, the edge of the boss 8 is provided with a chamfer or fillet. Through the setting of chamfer or fillet, reduce the friction of valve block 2 between rotation in-process and convex seat 8, reduce the damage of valve block 2 working process.

Similarly, in order to reduce the abrasion of the boss 8 to the valve plate 2, a rubber pad can be arranged on the upper surface of the boss 8, and the damage of the boss 8 to the valve plate 2 in the rotating process of the valve plate 2 is reduced through the arrangement of the rubber pad. The arrangement form of the convex seat 8 is only a simple introduction of the example, and in the actual use process, technicians can reduce the friction damage between the valve plate 2 and the convex seat 8 in the rotation process of the valve plate 2 according to technical habits and other or other various modes of other prior art means, so that the service life of the valve plate 2 is ensured.

Further, the opening direction of the exhaust hole 3 is parallel to the height direction of the body 1 or forms an included angle.

Specifically, when the opening direction of the exhaust hole 3 is parallel to the height direction of the body 1, that is, the exhaust hole 3 sequentially penetrates through the base 6 and the boss 8 along the height direction of the base 6, and the exhaust hole 3 is of a circular structure. The air flow discharged from the air outlet side of the air outlet hole 3 is vertically upward impacted due to the vertical arrangement of the air outlet hole 3.

Specifically, when the opening direction of the exhaust hole 3 forms an included angle with the height direction of the body 1, the included angle is an acute angle, and at this time, the exhaust hole 3 is in an elliptical shape. Exhaust hole 3 can incline to the right for the gas of exhaust in the exhaust hole 3 is towards the slope blowout of right side, and the refrigerant impact makes the 4 perks that make of second section, and makes second section 4 produce the effort of right motion, and under the effect of first section 5 water conservancy diversion, valve block 2 is round 7 anticlockwise rotations of neck seat.

Similarly, the exhaust hole 3 can also incline to the left, so that the gas exhausted from the exhaust hole 3 is obliquely ejected towards the left side, the second section 4 tilts upwards due to the impact of the refrigerant, the second section 4 generates acting force moving leftwards, and the valve plate 2 rotates clockwise around the neck seat 7 under the action of the flow guide of the first section 5 adjacent to the valve plate 2.

Further, one side of the valve plate 2, which is far away from the neck seat 7, is abutted against the upper surface of the convex seat 8, and one side of the valve plate 2, which is close to the neck seat 7, is rotatably connected with the neck seat 7. In order to avoid that the valve plate 2 is inclined as a whole, so that the side of the valve plate 2 close to the neck seat 7 contacts the base 6, part of the flange still may collide with the base 6 during rotation.

Optionally, the neck seat 7 is provided with a lifting seat 9, and the height of the lifting seat 9 is the same as that of the convex seat 8; the whole structure of the valve plate 2 is moved upwards through the arrangement of the lifting seat 9. The valve plate 2 is in a horizontal state, when the exhaust hole 3 is in a closed state, the second section 4 is abutted to the upper surface of the convex seat 8, so that the exhaust hole 3 is covered, and a gap is formed between the lower surface of the second section 4 and the base 6; when the exhaust hole 3 is in an opening state, the valve plate 2 is not in contact with the base 6, so that the valve plate 2 is abraded in the rotating process, and the service life of the valve plate 2 is prolonged.

Specifically, the rotating part is a bearing 10, the bearing 10 is sleeved outside the neck seat 7 of the body 1, and the bearing 10 is positioned on the upper side of the lifting seat 9; the valve plate 2 is fixedly arranged on one side of the bearing 10 far away from the neck seat 7. The stability of the rotation process of the valve plate 2 is ensured through the arrangement of the bearing 10.

Further, the section of the bearing 10 in the radial direction of the neck seat 7 completely covers the section of the elevated seat 9 in the radial direction of the neck seat 7. In the use, bearing 10 covers on raising seat 9 completely for after valve block 2 installed on bearing 10, any position of valve block 2 can not with raise and contact between the seat 9, and then avoid the valve seat in the rotation process valve block 2 with raise the possibility of the seat between 9 friction.

Alternatively, the cross-section of the elevation seat 9 in the radial direction of the neck seat 7 is circular for ease of machining and installation. Through the circular arrangement, when the lifting seat 9 and the neck seat 7 are detachably mounted, the lifting seat 9 and the neck seat 7 are conveniently mounted; when the lifting seat 9 and the neck seat 7 are integrally formed, the ring shape can also increase the overall aesthetic property. Meanwhile, the lifting seat 9 is arranged to be annular in the radial direction of the neck seat 7, so that the size of the lifting seat 9 can be conveniently selected according to the diameter of the bearing 10.

Further, the bearing 10 and the neck seat 7 are in interference fit. The interference fit prevents gaps from being generated between the inner ring of the bearing 10 and the two mating surfaces on the outer peripheral side of the neck seat 7, and prevents the inner ring of the bearing 10 and the two mating surfaces on the outer peripheral side of the neck seat 7 from being seriously worn due to the gaps, so that the bearing 10 rotates badly, generates heat or causes the abrasion in the bearing 10, thereby causing the damage of the bearing 10. Meanwhile, the bearing 10 and the neck seat 7 are in interference fit, and the firmness of connection between the bearing 10 and the neck seat 7 can be guaranteed. And moreover, the connection strength can be ensured through an interference fit connection mode, the number of parts for fixed connection is reduced, and the overall structure of the device is simplified.

Optionally, the bearing 10 is installed by cold pressing and hot sleeving.

Furthermore, one side of each valve plate 2 close to the neck seat 7 is fixedly arranged on the outer peripheral side of the bearing 10, and the valve plates 2 continuously rotate around the neck seat 7 under the action of the bearing 10 under the action of the impact force of a cooling medium.

Similarly, each valve sheet 2 may be detachably provided on the outer circumferential side of the bearing 10. For example, the outer bearing 10 of bearing 10 is provided with the draw-in groove, is provided with the joint portion that matches with the draw-in groove on the valve block 2, and valve block 2 realizes the fixed connection of valve block 2 and bearing 10 through in going into the draw-in groove with joint portion card. Simultaneously, when one of them valve block 2 broke down, can take out in the draw-in groove through the joint portion with this valve block 2, change a new valve block 2 can, need not wholly change, practice thrift the cost.

Further, the second segment 4 is horizontally disposed on the base 6 with the exhaust hole 3 in a closed state. One end of the first section 5 in the length direction is connected with the upper surface of the second section 4; under the condition that the exhaust hole 3 is in an open state, one end of the second section 4, which is far away from the first section 5, is deformed and bent upwards. It should be noted that, in order to guarantee the water conservancy diversion effect of valve block 2 to the refrigerant, the second section 4 should be less than the first section 5 apart from the maximum height of base 6 for the maximum height of second section 4 after the upwards perk of second section 4, and second section 4 can not take place to interfere with first section 5 in deformation process. Thereby guarantee that second section 4 plays the effect of direction to the refrigerant, the refrigerant just can make valve block 2 rotate to the impact of first section 5, and then plays the effect of water conservancy diversion to the refrigerant.

Further, the end of the first section 5 connected to the second section 4 divides the second section 4 into a first portion 11 and a second portion 12. The first part 11 is used to cover the exhaust hole 3, and the second part 12 is used to engage with the adjacent valve plate 2 with a small gap. Meanwhile, in the rotation process of the valve plate 2, the second part 12 can also generate a force balance for the refrigerant, so that the stability of the valve plate 2 in the rotation process is ensured.

Optionally, the area of first portion 11 is greater than second portion 12, and through slightly being bigger with the area setting of first portion 11, can guarantee that valve block 2 can guarantee that first portion 11 covers exhaust hole 3 in the different positions of rotation process back valve block 2. Simultaneously, the area of second part 12 sets up a little less, reduces the condition that second part 12 covers exhaust hole 3 after valve block 2 rotates, and then makes the water conservancy diversion effect not good when avoiding second part 12 to cover exhaust hole 3. Moreover, a bending space can be provided for the arc-shaped structure of the first section 5 through the arrangement of the second part 12, so that the second section 4 is prevented from impacting the first section 5 in the process of tilting upwards after being impacted by a cooling medium, and then noise is generated or the second section 4 is damaged.

Further, with reference to fig. 2-7, in order to ensure the flow guiding effect of the valve plate 2, the orthographic projection of the first portion 11 of any valve plate 2 in the plane perpendicular to the rotation axis of the rotation part is completely located within the contour defined by the orthographic projection of the first section 5 of the valve plate 2 or the first section 5 of the adjacent valve plate 2 in the plane of the rotation axis of the rotation part. After the first portion 11 is impacted and bent by the refrigerant, a part of the refrigerant is guided by the first portion 11 to move leftwards, and the other part of the refrigerant is impacted upwards onto the surface of the first section 5, guided by the structure of the first section 5 and moves the first section 5. Meanwhile, the refrigerant discharged from the exhaust hole 3 impacts the first portion 11, the tilting of the first portion 11 also compresses the refrigerant between the first portion 11 and the first section 5, and the valve plate 2 is also driven to rotate by the compression force between the first portion 11 and the first section 5 and the pushing force of the first portion 11. Through the arrangement, the refrigerant rushing out from the exhaust hole 3 can be intercepted and impact the first section 5 to enable the valve plate 2 to rotate, and the flow guide effect is realized.

Further, the third portion may be provided in two forms, specifically, the third portion is provided in a concave arc structure toward the first portion 11 or the third portion is provided in a convex structure toward the first portion 11.

Specifically, when the third portion is disposed toward the first portion 11 in a concave arc structure, the orthographic projection of the fourth portion of the valve plate 2 in a plane perpendicular to the rotation axis of the rotation portion should completely cover the first portion 11 of the valve plate 2. The refrigerant is guided to the third part after the first part 11 is tilted, so that the blowing valve plate 2 rotates integrally.

Similarly, when the third portion is disposed in an outwardly convex arc structure toward the first portion 11, an orthographic projection of the fourth portion of the valve plate 2 in a plane perpendicular to the rotation axis of the rotating portion completely covers the first portion 11 of the adjacent valve plate 2 of the valve plate 2, so that the refrigerant guided by the first portion 11 is blown to the third portion of the adjacent valve plate 2, and the valve plate 2 is driven to rotate.

Further, the structure of the valve plate 2 is simple, and the valve plate 2 is convenient to produce, process and manufacture. It should be noted that, because the second section 4 needs to cover the exhaust hole 3, and needs to bear the impact force of the refrigerant with a certain pressure, and needs to deform under the impact force of the high-pressure refrigerant gas, and needs to return to the original state after deformation to still maintain the sealing operation of the exhaust hole 3. Therefore, the valve plate 2 can be made of metal or other materials meeting the above requirements in the prior art.

Further, in order to avoid the interference of the process of bending deformation of the second segment 4 with the adjacent second segment 4, a hollowed-out portion 13 is provided on one side of the first portion 11 close to the neck seat 7. After the first part 11 is provided with the hollow part 13, the edge section of the first part 11, which is far away from the second part 12, of the same valve plate 2 is a broken line section, and the material cost of the valve plate 2 can be saved.

Likewise, the side of the second portion 12 close to the neck seat 7 may also be provided with a hollow-out portion 13, so as to ensure that the second portion 12 of one valve plate 2 does not affect the bending deformation of the first portion 11 of the adjacent valve plate 2.

Referring to fig. 1-8, the present embodiment further discloses a compressor, which includes the above-mentioned exhaust structure. When high-pressure gas rushes out from the exhaust hole 3 of the body 1, the high-pressure gas impacts the second section 4 of the valve plate 2, the second section 4 is stressed and deformed after being impacted, and then the high-pressure gas impacts the first section 5 to generate rotating power for the valve plate 2. Under the condition that the valve plate 2 rotates, the valve plate 2 deforms successively to disperse, absorb and guide flushed high-pressure gas to disperse uniformly, so that the inside of the compressor is stressed uniformly. Meanwhile, the high-pressure gas can be prevented from intensively impacting the running click rotor and stator in the compressor. The valve plates 2 are used for decomposing and bearing the impact of high-pressure gas, so that the service life of the valve plates 2 is prolonged, and the service life of the compressor is further prolonged. And, the valve block 2 can also utilize the centripetal force to play the effect of oil-gas separation under the high-speed condition of rotating.

Further, the compressor further includes a muffler 14, and the above-described exhaust structure is provided in the muffler 14. The noise generated when the compressor works is reduced through the arrangement of the silencer 14, and meanwhile, the oil path of the air flow can be changed through the arrangement of the silencer 14. The rotation of the valve plate 2 enables the air flow to firstly shoot to the periphery and then rapidly move upwards, so that the air flow firstly uniformly impacts the inner wall of the inner cavity of the silencer 14, and then intensively impacts the rotor circulation hole of the motor, the flow guiding effect on the air flow is realized, the movement stability of the air flow is ensured, and the effects of shock absorption and noise reduction can be achieved.
