A novel exhaust valve and a linear exhaust structure thereon

Abstract

The present invention discloses a novel linear exhaust structure for an exhaust valve, which includes a relief valve disc, a relief structure, an intake passage A and an exhaust passage A. The relief valve disc is made of an elastic material, and is provided with a relief passage and a relief hole thereon. The relief hole is a micro-scratch hole that penetrates the outer wall of the relief valve disc and communicates with the relief passage. In the natural state of the relief structure, the relief hole is kept in a slightly open state. The intake passage A and the exhaust passage A are respectively communicated with both ends of the relief hole. By means of the relief structure, the relief hole in the form of a micro-scratch hole structure is in a slightly open state. At this time, the opening of the relief hole is in the maximum state. When exhausting, according to the principle that the air pressure generates a force acting on the relief hole to cause the deformation of the relief valve disc, under different air pressures, the relief hole will deform, and the greater the air pressure, the greater the deformation, and the corresponding relief hole will become smaller, so as to control the exhaust rate and keep it at a stable value.

Description

Technical Field

[0001] The present invention relates to an exhaust valve, and particularly to a novel exhaust valve and a linear exhaust structure thereon. Background Art

[0002] At present, linear valves on the market are all solenoid valves. Based on the principle of solenoid valves, some improvements have been made on this basis, so that a balance is generated between the spring force and the electromagnetic force under any coil current. The magnitude of the coil current or the magnitude of the electromagnetic force will affect the stroke of the plunger and the opening of the valve, and there is an ideal linear relationship between the valve opening (flow rate) and the coil current (control signal). Therefore, it can control the opening of the valve according to different air pressures, so that it can discharge an equal amount of gas per unit time.

[0003] However, due to the adoption of the principle of solenoid valves, the structure of the linear valve becomes relatively complex and has a high production cost. Summary of the Invention

[0004] One object of the present invention is to provide a novel linear exhaust structure for an exhaust valve, which has the advantages of simple structure, low production cost, etc.

[0005] The above technical object one of the present invention is achieved through the following technical solutions:

[0006] A novel linear exhaust structure for an exhaust valve includes a deflation valve sheet, a deflation structure, an intake passage A and an outlet passage A. An outer sleeve for inserting the deflation valve sheet is arranged outside the deflation valve sheet. The deflation valve sheet is made of an elastic material, and a deflation passage and a deflation hole are arranged thereon. The deflation hole is a micro-scratch hole penetrating through the outer wall of the deflation valve sheet and communicating with the deflation passage. The outer wall of the open end of the deflation passage is hermetically arranged with the outer sleeve; the deflation structure keeps the deflation hole in a slightly open state in the natural state; the intake passage A and the outlet passage A are respectively communicated with both ends of the deflation hole, and the acting force of the gas entering from the intake passage A on the deflation hole is opposite to the acting force of the deflation structure to open the deflation hole.

[0007] With such a setting, the deflation structure makes the deflation hole in the form of a micro-scratch hole in a slightly open state, and at this time, the opening of the deflation hole is in the maximum state. When deflating, according to the principle that the acting force generated by the air pressure on the deflation hole causes the deflation valve sheet to deform, under the action of different air pressures, the deformation at the deflation hole is different, that is, the greater the air pressure, the greater the deformation, and the corresponding deflation hole will become smaller. Based on this principle, the deflation rate is controlled to keep the deflation rate at a stable value.

[0008] More preferably, the air leakage structure is an air leakage needle, one end of the air leakage needle is inserted on the air leakage valve sheet, and the other end penetrates through the air leakage hole; the air leakage direction of the air leakage hole is from the outside of the air leakage valve sheet to the inside.

[0009] More preferably, the air leakage hole is arranged on the side wall of the air leakage valve sheet, and an air inlet channel A is formed between the outer wall of the air leakage valve sheet and the inner wall of the outer sleeve.

[0010] With such a setting, the aperture size of the air leakage hole passage is ensured by fixing the micro needle, so as to control the air leakage rate. The structure is very simple, making production and installation very convenient.

[0011] More preferably, the air leakage hole is arranged at the end of the air leakage valve sheet, and the air leakage structure is two extrusion rib strips arranged on the outer side wall of the air leakage valve sheet and centered on the axis. The two extrusion rib strips are in interference fit with the inner wall of the outer sleeve, and the air inlet channel A is communicated with the air leakage channel.

[0012] With such a setting, the size of the air leakage hole is controlled by the extrusion rib strips and the interference fit, so as to control the air leakage rate.

[0013] More preferably, the air leakage hole and the two extrusion rib strips are arranged coplanarly.

[0014] With such a setting, when the extrusion rib strips are squeezed, the effect of slightly opening the air leakage hole can be better achieved, and the deformation law under air pressure is more controllable.

[0015] More preferably, the air leakage valve sheet is made of rubber or silica gel material.

[0016] The second object of the present invention is to provide a new type of exhaust valve.

[0017] The above technical object two of the present invention is achieved by the following technical solutions:

[0018] A new type of exhaust valve, including a clutch mechanism, a nozzle and a linear exhaust structure. An air inlet channel B is arranged on the nozzle; the linear exhaust structure is inserted into the clutch mechanism and sequentially engages and disengages with the nozzle as the clutch mechanism is powered on and off; a gap is arranged between the linear exhaust structure and the inner wall of the clutch mechanism to form an air outlet channel B, and an elastic member is arranged between the nozzle and the linear exhaust structure to keep the nozzle and the linear exhaust structure separated; the air inlet channel B is communicated with the air outlet channel B / air outlet channel A respectively as the clutch mechanism is disengaged / engaged.

[0019] In this way, the clutch device drives the linear exhaust structure to move, so that it can separate and close with the air nozzle, thus forming two states: separate and close. In the separate state, the air inlet channel B is connected with the air outlet channel B, and it is in a rapid exhaust state. In the closed state, the air inlet channel B is connected with the air outlet channel A, and it is in a linear exhaust state. This structure replaces the previous practice of requiring both rapid discharge valves and linear exhaust valves in medical and health products, and realizes that one valve can achieve two functions.

[0020] It is further preferred that: the clutch mechanism includes an energized coil and an iron core, the energized coil includes a wire frame and a wire package, the wire package is arranged outside the wire frame, and the iron core is inserted into the wire frame; the iron core and the outer shell are arranged in one piece, and the air nozzle is made of magnetic material. With such an arrangement, the iron core and the air nozzle are attracted to each other by the principle that the iron core becomes magnetic after the energized coil is energized.

[0021] Further preferably, a plurality of convex ribs for retaining the radially limited iron core are arranged on the inner wall of the wire rack.

[0022] This arrangement maintains the stability of the iron core during axial sliding, ensuring that it will not shake left and right when powered on, thereby affecting the sealing.

[0023] Further preferably, a gasket for maintaining the sealing property of the connection between the tuyere and the iron core is provided at one end of the iron core facing the tuyere, and a vent hole is provided on the gasket.

[0024] With such arrangement, the gasket ensures the sealing of the connection between the air nozzle and the linear exhaust structure, so that the wind will not enter the air outlet channel B from the air inlet channel B to affect the linear exhaust.

[0025] Further preferably, the air relief valve plate is integrally arranged with the gasket, the air vent is communicated with the air relief channel, and the air relief hole is located on an end surface away from the opening of the air vent.

[0026] With such arrangement, when the extruded ribs are used as the deflation structure, the deflation valve plate and the gasket are arranged as an integrated structure by utilizing their characteristics, so that the overall structure is simpler.

[0027] Further preferably, an outer frame is arranged outside the energized coil, a socket for inserting the nozzle head is arranged on the outer frame, one end of the outer frame relative to the socket is open, and a patch for positioning the wire rack is installed at the open end of the outer frame.

[0028] With such arrangement, the exhaust valve can be integrally installed and fixed by arranging the outer frame and the patch.

[0029] Further preferably, the elastic member is a spring.

[0030] A third object of the present invention is to provide a novel exhaust valve.

[0031] The third technical object of the present invention is achieved by the following technical solutions:

[0032] A new type of exhaust valve includes a clutch mechanism, a nozzle, and the above-mentioned linear exhaust structure. A iron core is arranged in the clutch mechanism, which opens / clogs the air outlet of the nozzle with the on / off power of the clutch mechanism. A gap is formed between the iron core and the inner wall of the clutch mechanism to form an air outlet channel B; an elastic member is arranged between the nozzle and the iron core to keep the nozzle and the iron core separated, and an exhaust hole communicating with the intake channel A on the linear exhaust structure is arranged on the nozzle.

[0033] With such a setting, the linear exhaust structure is driven by the clutch device to move, so that the separation and combination actions occur between the linear exhaust structure and the nozzle, thus forming two states of separation and combination. In the separated state, the intake channel B is communicated with the air outlet channel B, and at this time, it is in the rapid exhaust state. In the combined state, the gasket blocks the air outlet of the nozzle, so that the gas can only be discharged from the exhaust hole, that is, it is exhausted through the linear exhaust structure, so it is in the linear air leakage state. This structure replaces the previous practice of using both a rapid discharge valve and a linear exhaust valve on medical and health products, and realizes that one valve can achieve two functions.

[0034] Further preferably: The clutch mechanism further includes an energized coil, the energized coil includes a coil holder and a coil package, the coil package is arranged outside the coil holder, the iron core is inserted into the coil holder, and one end of the nozzle is inserted into the coil holder and is made of magnetic material; the outer sleeve is arranged on the coil holder.

[0035] With such a setting, the iron core and the nozzle are attracted to each other by the principle that the iron core becomes magnetic after the energized coil is energized.

[0036] Further preferably: A limiting step for keeping the exhaust hole and the intake channel A in alignment is arranged at one end of the coil holder where the nozzle is inserted.

[0037] With such a setting, the nozzle is axially limited, so that the axes of the exhaust hole and the intake channel A are on the same horizontal plane, and misalignment will not occur due to the sliding of the nozzle.

[0038] Further preferably: An annular cutting groove is arranged around the exhaust hole.

[0039] With such a setting, the annular cutting groove can be provided, and it is not necessary to ensure that the exhaust hole and the intake channel A are exactly on the same axis to be communicated, which is more convenient for assembly.

[0040] Further preferably: A plurality of convex ribs for radially limiting the iron core are arranged on the inner wall of the coil holder.

[0041] With such a setting, the stability of the iron core during axial sliding is maintained, ensuring that there is no left - right shaking during power - on, which may affect the sealing performance.

[0042] Further preferably, a gasket for maintaining the connection sealing between the air nozzle and the iron core is provided at one end of the iron core facing the air nozzle.

[0043] With such a setting, the connection sealing between the air nozzle and the linear exhaust structure is ensured by the gasket, so that air does not enter the air outlet channel B from the air inlet channel B, which may affect the linear exhaust.

[0044] Further preferably, an outer frame is provided outside the energized coil. A jack for inserting the head of the air nozzle is provided on the outer frame. One end of the outer frame relative to the jack is open, and a patch for positioning the wire frame is installed at the open end of the outer frame.

[0045] With such a setting, through the setting of the outer frame and the patch, the overall installation and fixation of the exhaust valve are realized.

[0046] Further preferably, the elastic member is a spring.

[0047] In summary, the present invention has the following beneficial effects:

Through the cooperation of the air vent hole with the micro - scratch hole structure and the air release structure, combined with the deformable setting of the air release valve piece, the opening size of the air vent hole can be automatically adjusted according to the size of the air release pressure, so that linear exhaust can be achieved with a simple structure;

[0049] 2. Through the setting of the clutch mechanism, the exhaust valve has two functions: rapid exhaust and linear exhaust. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0069] The present invention will be further described in detail below with reference to the accompanying drawings.

[0070] Embodiment 1: A novel linear exhaust structure for an exhaust valve, asFigure 1 and Figure 2 As shown in Figure 2 , it includes an outer sleeve 1 and a deflation valve piece 2, and the deflation valve piece 2 is inserted into the outer sleeve 1.

[0071] Among them, the deflation valve piece 2 is made of an elastic material such as rubber or silica gel. In this embodiment, rubber 2 material is used.

[0072] Referring to Figure 1 , a deflation channel 21 that does not penetrate the deflation valve piece 2 is provided on the axis of the deflation valve piece 2. An air vent 22 is provided on the side wall of the deflation valve piece 2. The air vent 22 penetrates the side wall and communicates with the deflation channel 21, and it is a micro-scratch hole (that is, in the natural state, under the elastic action of the rubber, the air vent 22 tends to be closed, which can be seen in Figure 2 and Figure 3 ).

[0073] As Figure 1 and Figure 2 shown, an air inlet hole 11 and a plug hole 12 with a diameter larger than the air inlet hole 11 are provided in the outer sleeve 1. The air inlet hole 11 and the plug hole 12 communicate and penetrate the outer sleeve 1. The deflation valve piece 2 is inserted into the plug hole 12, and a convex ring 23 is provided on the outer side wall of the opening end of the deflation channel 21 on the deflation valve piece 2. The diameter of the convex ring 23 is slightly larger than the diameter of the plug hole 12 to form an interference fit to achieve sealing after installation.

[0074] The outer diameter of the deflation valve piece 2 is smaller than the inner diameter of the plug hole 12, so that an air inlet channel A3 communicating with the air inlet hole 11 is formed between the outer wall of the deflation valve piece 2 and the inner wall of the plug hole 12.

[0075] In addition, a deflation structure 4 that can keep the air vent 22 in a slightly open state in the natural state is also provided on the deflation valve piece 2. In this embodiment, the deflation structure 4 is a deflation needle 41. One end of the deflation needle 41 is inserted into the deflation valve piece 2, and the other end penetrates the air vent 22. The air vent 22 is kept in a slightly open state by the diameter of the deflation needle 41. Among them, the deflation channel 21 in this embodiment is also the exhaust channel A.

[0076] When in use, the gas to be discharged enters from the air inlet hole 11, passes through the air inlet channel A3 and then enters the deflation channel 21 from the air vent 22 to achieve deflation. And because the air inlet channel A3 is outside the deflation valve piece 2, when the gas enters the air inlet channel A3, an air pressure will be formed outside the deflation valve piece 2 to form a pressure on both sides of the air vent 22 to press the deflation needle 41. The greater the air pressure, the greater the pressure, and the greater the deformation generated at the air vent 22, so that the opening of the air vent 22 will become smaller, thereby realizing the control of the deflation rate.

[0077] Embodiment 2: As Figure 1As shown, the difference from Embodiment 1 is that only the insertion holes 12 penetrating both ends are provided on the outer sleeve 1. The air release holes 22 are provided at one end of the air release valve piece 2 opposite to the opening end of the air release channel 21, and the air release holes 22 penetrate through this end and communicate with the air release channel 21.

[0078] Among them, in this embodiment, the air release channel 21 serves as the intake channel A3, and the insertion hole 12 communicating with the air release hole 22 serves as the exhaust channel A.

[0079] Such as Figure 2 and Figure 3 As shown, two extrusion rib strips 42 along the central axis are provided on the outer side wall of the air release valve piece 2 as the air release structure 4 of this embodiment, and the two extrusion rib strips 42 are in interference fit with the inner wall of the outer sleeve 1. Among them, the air release holes 22 and the two extrusion rib strips 42 are arranged coplanarly.

[0080] During use, the gas to be discharged enters from the air release channel 21, passes through the air release holes 22, and then is discharged from the insertion holes 12. Among them, when the gas enters the air release channel 21, the air pressure formed will generate an outward acting force on the inner wall of the air release channel 21, and the slight opening effect of the air release holes 22 is formed by the acting force generated by the inward extrusion of the extrusion rib strips 42. Therefore, the greater the air pressure, the greater the outward acting force generated on the inner wall, that is, the greater the acting force generated by the inward extrusion of the extrusion rib strips 42 is offset, so that the opening of the air release holes 22 becomes smaller.

[0081] Embodiment 3: A new type of exhaust valve, such as Figure 1 As shown, it includes an outer frame 5 and a clutch mechanism, a nozzle 7 and the linear exhaust structure in Embodiment 1 installed in the outer frame 5.

[0082] Referring to Figure 1 and Figure 3 , the clutch mechanism includes an energized coil 6 and an iron core 10. The energized coil 6 includes a coil holder 61 and a coil package 62. Baffles 611 are provided at both ends of the coil holder 61, and the coil package 62 is arranged outside the coil holder 61 between the two baffles 611.

[0083] Among them, the iron core 10 is integrally provided with the outer sleeve 1 in Embodiment 1. An installation hole 612 for inserting the iron core 10 is provided on the coil holder 61. The diameter of the installation hole 612 is larger than the diameter of the iron core 10. At the same time, a number of convex ribs 615 for radially limiting the iron core 10 are provided on the inner wall of the installation hole 612 (which can be seen in the appendix Figure 17 ), and the gaps formed between adjacent convex ribs 615, the iron core 10 and the installation hole 612 are the air outlet channels B.

[0084] One end of the installation hole 612 is open for the iron core 10 to be inserted, and the other end is provided with a blocking rib 613 to prevent the iron core 10 from slipping out.

[0085] The air nozzle 7 is arranged in a stepped shape, and an air intake channel B71 is arranged through it. One end of the outer frame 5 is open, and a patch 52 is installed at this end. The wire holder 61 is fixed in the outer frame 5 through the patch 52.

[0086] A jack 51 is arranged at one end of the outer frame 5 opposite to the opening. The smaller-diameter end of the air nozzle 7 is inserted into the jack 51, and the other end is inserted into the wire holder 61, and the step abuts against the end face of the outer frame 5.

[0087] A spring is sleeved between the air nozzle 7 and the iron core 10, and the elastic force of the spring separates the air nozzle 7 from the iron core 10.

[0088] A gasket 8 is installed at one end of the iron core 10 facing the air nozzle 7. The gasket 8 is made of the same material as the air release valve piece 2. An air vent hole 81 penetrating the gasket 8 is arranged on the gasket 8, and the air vent hole 81 is coaxially arranged with the air intake hole 11.

[0089] Working principle: When the clutch mechanism is not powered on, the air nozzle 7 and the iron core 10 are separated under the action of the elastic force of the spring. At this time, the air intake channel B71 is communicated with the air outlet channel B, and it is in a rapid exhaust state. When the clutch mechanism is powered on, the coil on the wire coil 62 is powered on, making the iron core 10 inside it magnetic. Under the action of magnetic attraction, it overcomes the elastic force of the spring. At this time, the iron core 10 and the air nozzle 7 are attracted to each other, and the air intake channel B71 is communicated with the air intake hole 11 on the iron core 10, that is, communicated with the air intake channel A3. At this time, the gas needs to pass through the air release hole 22, making the exhaust valve in a linear exhaust state.

[0090] Embodiment 4: A new type of exhaust valve, as Figure 11 and 12 shown. The difference from Embodiment 3 is that the linear exhaust structure in Embodiment 2 is adopted.

[0091] Moreover, the gasket 8 and the air release valve piece 2 are integrally arranged, that is, the air vent hole 81 and the air release channel 21 are also integrally arranged.

[0092] Embodiment 5: A new type of exhaust valve, as Figure 11 and 12 shown. The difference from Embodiment 3 is that the iron core 10 is not a linear exhaust structure. Among them, the gasket 8 is solid. When the energized coil 6 is energized, the iron core 10 contacts the air nozzle 7, and the gasket 8 completely blocks the outlet of the air nozzle 7.

[0093] An exhaust hole 72 is arranged on the side surface of the air nozzle 7, and the exhaust hole 72 penetrates the side wall of the air nozzle 7.

[0094] The outer sleeve 1 on the linear exhaust structure is integrally arranged on the wire holder 61, and the air intake hole 11 on the outer sleeve 1 penetrates the inner wall of the wire holder 61, so that when the air nozzle 7 is installed on the wire holder 61, the air intake hole 11 is communicated with the exhaust hole 72.

[0095] Referring to Figure 15 and Figure 16 , at one end of the air nozzle 7 inserted into the wire holder 61, there is a limited position step 614 for keeping the exhaust hole 72 and the intake passage A3 in alignment. An annular protrusion is provided on the outer side wall of the air nozzle 7 so that the air nozzle 7 is axially positioned between the wire holder 61 and the outer frame 5. At the same time, in order to facilitate assembly and ensure the communication between the exhaust hole 72 and the intake passage A3, an annular cut groove 73 is provided around the exhaust hole 72.

[0096] Referring to Figure 17 , a plurality of ribs 615 for radially limiting the iron core 10 are provided on the inner wall of the wire holder 61.

[0097] Embodiment 6: A new type of exhaust valve, as Figure 17 shown, is different from Embodiment 5 in that the linear exhaust structure in Embodiment 2 is adopted. Among them, a ventilation hole 616 communicating with the exhaust hole 72 is provided on the wire holder 61. Among them, the outer sleeve 1 is threadedly connected to the wire holder 61. When the outer sleeve 1 is installed on the wire holder 61, the air leakage channel 21 communicates with the ventilation hole 616.

[0098] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the protection scope of the present invention, it is protected by the patent law.
