Description

Technical Field

[0001] This invention relates to the field of aerosol generation, and more particularly to aerosol generation apparatus. Background Technology

[0002] Micro-oil mist lubrication typically involves mixing compressed air (such as air) with a very small amount of lubricating oil, vaporizing the mixture to form an oil mist containing micron-sized droplets. This mist is then sprayed at high speed through nozzles onto the cutting area or moving parts, effectively cooling and lubricating them. The core component is the pump body, where the reciprocating motion of the plunger completes the oil suction and pressure actions. The pressure-out lubricating oil mixes with the compressed air to form an oil mist. Existing plunger pumps have an adjusting rod for regulating the oil delivery rate. By screwing the adjusting rod in and out, the piston stroke is adjusted, thus controlling the plunger stroke and consequently the oil delivery rate. When the adjusting rod is screwed to its limit, the piston stroke is very small, and the piston cannot move normally, preventing the plunger from discharging grease and causing equipment failure.

[0003] Therefore, there is an urgent need for an aerosol generating device that ensures the plunger will not malfunction due to adjustments to the adjusting rod, in order to overcome the above-mentioned defects. Summary of the Invention

[0004] The purpose of this invention is to provide an aerosol generating device that ensures the plunger will not malfunction due to adjustments of the adjusting rod.

[0005] To achieve the above objectives, the aerosol generating device provided by the present invention includes a base, a liquid-pushing assembly, a through-hole component, an output assembly, and an adjusting rod. The base, from left to right, is provided with a connection cavity, a mounting cavity, and a sliding cavity. The base also includes a liquid inlet channel and a first air inlet, which communicates with the connection cavity. The output assembly is installed in the connection cavity, and the through-hole component is installed in the mounting cavity. The through-hole component has a liquid storage channel that communicates with the liquid inlet channel. The liquid-pushing assembly is slidably installed in the sliding cavity, and includes a plunger that passes through the liquid storage channel. The liquid-pushing assembly slides to the left within the sliding cavity. The plunger is driven into the liquid storage channel, pushing the liquid in the storage channel toward the output component. Compressed air input from the first air inlet flows into the output component. The liquid pushing component slides to the right in the sliding cavity, driving the plunger out of the liquid storage channel, creating a negative pressure in the liquid storage channel and drawing the liquid in the inlet channel into the liquid storage channel. The adjusting rod is adjustable in the sliding cavity, and the adjusting rod is used to adjust the amount of plunger penetration in the liquid storage channel. The adjusting rod includes a limiting part provided in the sliding cavity. The liquid pushing component is also slidably provided in the limiting part. The limiting part includes a blocking structure that restricts the liquid pushing component to always maintain the same sliding distance.

[0006] Preferably, the liquid pushing assembly also includes a piston that is slidably mounted in the sliding chamber, a limiting part passing through the piston, the piston sliding left and right along the limiting part, and the right end of the plunger being inserted into the piston by means of a ball joint connection.

[0007] Preferably, the blocking structure includes a first blocking end formed at the left end of the limiting portion and a second blocking end formed at the right end of the limiting portion. The first blocking end is inserted into the piston, and the second blocking end is disposed outside the piston. The first blocking end and the second blocking end are spaced apart in the left-right direction, and the sliding distance of the liquid pushing assembly is the distance between the first blocking end and the second blocking end.

[0008] Preferably, the diameter of the limiting portion is smaller than both the diameter of the first blocking end and the diameter of the second blocking end.

[0009] Preferably, the insert is provided with a liquid inlet, the liquid storage channel is connected to the liquid inlet channel through the liquid inlet, and the plunger pushes the liquid in the liquid inlet channel toward the output component by passing over the liquid inlet.

[0010] Preferably, the aerosol generating device of the present invention further includes an indicator rod that passes through an adjusting rod. The left end of the indicator rod is mounted on the piston, and the right end of the indicator rod is located outside the base. The indicator rod slides back and forth synchronously with the piston.

[0011] Preferably, the piston has a connecting cavity, the left end of the indicator rod is located in the connecting cavity, the liquid pushing assembly also includes a connecting cover, the connecting cover is connected to the left end of the indicator rod, the left end of the indicator rod forms a contact body located in the connecting cover, and the right end of the plunger passes through the connecting cover and contacts the contact body by means of spherical contact.

[0012] Preferably, the right end face of the plunger is a curved structure, and the end face of the contact body is a flat structure. The curved structure abuts against the flat structure, and the right end of the plunger is locked inside the connecting cover by a snap ring.

[0013] Preferably, the right end of the connecting cavity has a stepped surface structure, the right end of the contact body extends outward in the circumferential direction to form a positioning platform, the positioning platform is connected to the stepped surface structure, the right end of the connecting cover is connected to the positioning platform, and the left end of the connecting cover is locked to the connecting cavity by a snap ring.

[0014] Preferably, the seat body is also provided with a second air inlet. The piston divides the sliding chamber into a sliding left chamber and a sliding right chamber. A first spring is installed in the sliding left chamber. The first spring abuts against the piston. The first spring always has the tendency to push the piston to slide to the right. The seat body is provided with a second air inlet that communicates with the sliding right chamber.

[0015] Compared with the prior art, in this invention, no matter how the adjusting rod is adjusted to adjust the amount of oil dispensed, the travel distance of the pushing component remains constant with each movement. That is, this application extends the adjusting rod so that the pushing component slides to the limiting part. The limiting part is provided with a blocking structure that restricts the pushing component to always maintain the same sliding distance. The travel distance of the pushing component remains unchanged, and it will not be unable to move normally due to the adjustment of the amount of oil dispensed. The plunger can normally push out oil, and the oil storage channel can normally receive oil, ensuring that the plunger will not be unable to move normally due to the adjustment of the adjusting rod.

[0027] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] This invention discloses an aerosol generating device 100 for dispensing minute amounts of liquid and outputting compressed air. The output compressed air and liquid mix and vaporize at a nozzle to form an aerosol containing micron-sized droplets. This invention uses a solution as a lubricating oil in its description, but it is understood that the solution is not limited to lubricating oil and can be water, alcohol, or various chemical solvents. When compressed air and lubricating oil mix and vaporize to form micron-sized droplet oil mist, it is sprayed at high speed through a nozzle onto the cutting area or moving parts for cooling and lubrication.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11As shown, the aerosol generating device 100 of the present invention includes a base 10, a liquid pushing assembly 20, a through-hole member 30, an output assembly 40, and an adjusting rod 50. The base 10 is provided with a connection cavity 11, a mounting cavity 12, and a sliding cavity 13 from left to right. The base 10 also has a liquid inlet channel 14 and a first air inlet 15. The first air inlet 15 communicates with the connection cavity 11. The output assembly 40 is installed in the connection cavity 11, and the through-hole member 30 is installed in the mounting cavity 12. The through-hole member 30 has a liquid storage channel 31, which communicates with the liquid inlet channel 14. The liquid pushing assembly 20 is slidably installed in the sliding cavity 13, and the liquid pushing assembly 20 includes a plunger 21 that passes through the liquid storage channel 31. The liquid-pushing assembly 20 slides to the left within the sliding chamber 13, causing the plunger 21 to penetrate into the liquid storage channel 31. This pushes the liquid in the liquid storage channel 31 towards the output assembly 40, achieving the dispensing action. Compressed air input from the first air inlet 15 flows into the output assembly 40. The liquid flowing into the output assembly 40 and the compressed air flowing into the output assembly 40 ultimately mix at the tail end of the output assembly 40, forming an aerosol containing micron-sized droplets. The liquid-pushing assembly 20 slides to the right within the sliding chamber 13, causing the plunger 21 to exit the liquid storage channel 31. This creates a negative pressure in the liquid storage channel 31, drawing the liquid from the inlet channel 14 into the liquid storage channel 31. The adjusting rod 50 is adjustable in its insertion depth within the sliding chamber 13. The adjusting rod 50 is used to adjust the insertion depth of the plunger 21 in the liquid storage channel 31, thereby adjusting the dispensing volume. A larger insertion depth of the plunger 21 results in a higher dispensing volume, while a smaller insertion depth results in a smaller dispensing volume. The penetration amount of the plunger 21 refers to the degree to which the plunger 21 penetrates the insert 30. The adjusting rod 50 includes a limiting part 51 disposed in the sliding cavity 13, and the liquid pushing assembly 20 is also slidably disposed in the limiting part 51. The limiting part 51 includes a blocking structure that limits the liquid pushing assembly 20 to always maintain the same sliding distance.

[0030] In this invention, regardless of how the adjusting rod 50 is adjusted to adjust the amount of oil dispensed, the travel distance of the pushing component 20 remains constant with each movement. That is, by "extending" the adjusting rod 50, the pushing component 20 is slidably positioned in the limiting part 51. The limiting part 51 has a blocking structure that restricts the pushing component 20 to always maintain the same sliding distance. The travel distance of the pushing component 20 remains constant, and it will not be unable to move normally due to the adjustment of the amount of oil dispensed. The plunger 21 can normally dispense oil, and the reservoir channel 31 can normally receive oil, ensuring that the plunger 21 will not be unable to move normally due to the adjustment of the adjusting rod 50.

[0031] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the liquid-pushing assembly 20 also includes a piston 22 that is slidably mounted in the sliding cavity 13. A limiting part 51 passes through the piston 22, and the piston 22 slides left and right along the limiting part 51. The right end of the plunger 21 is inserted into the piston 22 via a ball joint connection. The limiting part 51 provides guidance for the sliding of the piston 22, making the movement of the piston 22 more stable. The ball joint connection of the right end of the plunger 21 allows for multi-directional adjustment during movement, reducing the risk of jamming.

[0032] like Figures 3 to 9 As shown, the blocking structure includes a first blocking end 52 formed at the left end of the limiting portion 51 and a second blocking end 53 formed at the right end of the limiting portion 51. The first blocking end 52 is inserted into the piston 22, and the second blocking end 53 is disposed outside the piston 22. The first blocking end 52 and the second blocking end 53 are spaced apart in the left-right direction. The sliding distance of the liquid pushing assembly 20 is the distance between the first blocking end 52 and the second blocking end 53, i.e. Figure 9 The center distance L1 (actually smaller than the center distance L1, because it is necessary to consider setting a matching blocking structure on the piston 22, but for ease of representation, the center distance L1 is used as the sliding stroke of the piston 22).

[0033] When piston 22 stops due to obstruction by the first blocking end 52, plunger 21 enters the liquid storage channel 31 and reaches its leftmost limit position. When piston 22 stops due to obstruction by the second blocking end 53, plunger 21 exits the liquid storage channel 31 and reaches its rightmost limit position. The first blocking end 52 and the second blocking end 53 limit the piston 22 to slide only within the distance defined by these two ends, and it must slide within this distance. The distance traveled by piston 22 each time is constant.

[0034] Preferably, the diameter of the limiting part 51 is smaller than the diameter of both the first blocking end 52 and the second blocking end 53. A sealing ring is installed on the first blocking end 52, and the piston 22 slides on the first blocking end 52. The sealing ring can prevent air leakage.

[0035] like Figures 3 to 6 As shown, the insert 30 is provided with a liquid inlet 32, and the liquid storage channel 31 is connected to the liquid inlet channel 14 through the liquid inlet 32. The plunger 21 passes over the liquid inlet 32 ​​and pushes the liquid in the liquid inlet channel 14 toward the output component 40.

[0036] It can be understood that the greater the penetration depth of the plunger 21, that is, the more of the plunger 21 penetrates into the liquid storage channel 31, the more oil it can push out, and vice versa. For example, Figure 4 The penetration depth of the middle plunger 21 should be greater than Figure 6 The penetration depth of the middle plunger 21, therefore Figure 4 The middle plunger 21 can push out more oil.

[0037] It should be noted that when the plunger 21 has not yet passed the inlet 32, the oil in the reservoir 31 will not be pushed out due to insufficient pressure difference. Only after the plunger 21 has passed the inlet 32, i.e., when the plunger 21 is in the position of... Figure 3 The oil in the storage channel 31 can only be pushed out when the state shown is reached, because the oil in the storage channel 31 cannot flow back to the inlet channel 14, and can only be output in one direction to push out the oil in the storage channel 31.

[0038] like Figures 3 to 9 As shown, the aerosol generating device 100 of the present invention also includes an indicator rod 60. The indicator rod 60 passes through the adjusting rod 50, with its left end mounted on the piston 22 and its right end located outside the base 10. The indicator rod 60 slides back and forth synchronously with the piston 22. As the indicator rod 60 slides back and forth synchronously with the piston 22, its right end continuously enters and exits the base 10. By observing whether the right end of the indicator rod 60 continuously enters and exits the base 10, it can be determined whether the aerosol generating device 100 is operating normally.

[0039] like Figures 3 to 9 As shown, the piston 22 has a connecting cavity 221, and the left end of the indicator rod 60 is located in the connecting cavity 221. The liquid-pushing assembly 20 also includes a connecting cover 23, which is connected to the left end of the indicator rod 60. The left end of the indicator rod 60 forms a contact body 61 located within the connecting cover 23. The right end of the plunger 21 passes through the connecting cover 23 and contacts the contact body 61 via a spherical contact. The connecting cover 23 connects the piston 22, plunger 21, and contact body 61 together, enhancing the overall stability of the structure and ensuring that the three can move synchronously. The right end of the plunger 21 contacts the contact body 61 via a spherical contact, allowing the right end of the plunger 21 to be inserted into the piston 22 via a ball joint connection, enabling the plunger 21 to be multi-directionally adjustable during movement.

[0040] Furthermore, the right end face of the plunger 21 is a curved structure, while the end face of the contact body 61 is a flat structure. The curved structure abuts against the flat structure, and the right end of the plunger 21 is locked inside the connecting cover 23 by a snap ring. The curved structure can rotate in multiple directions on the flat structure, thereby realizing the multi-directional rotation adjustment of the plunger 21.

[0041] like Figures 3 to 6As shown, a stepped surface structure 222 is formed at the right end of the connecting cavity 221. The right end of the contact body 61 extends outward in the circumferential direction to form a positioning platform 62. The positioning platform 62 is connected to the stepped surface structure 222. The right end of the connecting cover 23 is connected to the positioning platform 62. The left end of the connecting cover 23 is locked to the connecting cavity 221 by a snap ring. The snap ring locks the connecting cover 23 in the connecting cavity 221. The stepped surface structure 222 can provide positioning for the positioning platform 62, which makes the plunger 21, piston 22 and indicator rod 60 reliably and stably connected together.

[0042] like Figures 3 to 6 As shown, the seat 10 also has a second air inlet 16. The piston 22 divides the sliding chamber 13 into a sliding left chamber and a sliding right chamber. A first spring 24 is installed in the sliding right chamber. The first spring 24 abuts against the piston 22 and has a constant tendency to push the piston 22 to slide to the right. The seat 10 has a second air inlet 16 that communicates with the sliding right chamber. Compressed air is injected into the sliding right chamber through the second air inlet 16. The compressed air pushes the piston 22 to slide to the left, causing the plunger 21 to penetrate the liquid storage channel 31 and push the oil to the output assembly 40. At this time, the first spring 24 is compressed. After the injection of compressed air into the sliding right chamber stops, the first spring 24 returns to its original position and pushes the piston 22 to slide to the right, causing the plunger 21 to exit the liquid storage channel 31.

[0043] like Figures 3 to 6 As shown, the output component 40 can adopt the existing structure, and a one-way valve 41 to prevent liquid backflow is provided in the output component 40.

[0044] A second spring 70 is also installed in the sliding right chamber. The second spring 70 abuts against the adjusting rod 50 and has a constant tendency to push the adjusting rod 50 to move to the left. The second spring 70 improves the feel of operating the adjusting rod 50. A limit head 80 is installed at the right end of the adjusting rod 50, and the right end of the indicator rod 60 is also inserted into the limit head 80. The limit head 80 is provided with an observation port through which the movement of the indicator rod 60 can be observed.

[0045] When the adjusting rod 50 is inserted into the sliding cavity 13, and the limiting head 80 is aligned with the seat 10, the adjusting rod 50 reaches its limit position and can no longer be inserted into the sliding cavity 13. The state at this point is as follows: Figure 3 , Figure 4 and Figure 5 As shown, this is the adjustment that allows plunger 21 to achieve its maximum insertion depth. After properly unscrewing the adjusting lever 50, as... Figure 6 As shown, even if the plunger 21 penetrates into the liquid storage channel 31 and reaches the leftmost limit position, the penetration amount of the plunger 21 is less than... Figure 3 , Figure 4 and Figure 5The amount of oil pushed out by the plunger 21 is relatively small because the amount of oil pushed out is limited. Therefore, by screwing in or out the adjusting rod 50, the amount of oil pushed out by the plunger 21 can be adjusted, thus achieving the adjustment of the oil supply.

[0046] The following is a brief description of the working process of the aerosol generating device 100 of the present invention: Compressed gas flows into the assembly chamber 11 through the first air inlet 15 and then into the output assembly 40. The compressed gas is input into the sliding right chamber through the second air inlet 16. The compressed gas pushes the piston 22 to slide to the left, causing the plunger 21 to pass into the liquid storage channel 31. After the plunger 21 passes the liquid inlet 32, it pushes the oil in the liquid storage channel 31 towards the output assembly 40. The oil output from the output assembly 40 and the compressed air finally mix at the nozzle to form micron-sized droplet oil mist. After the injection of compressed air into the sliding right chamber stops, the first spring 24 pushes the piston 22 to slide to the right, causing the plunger 21 to pass out of the liquid storage channel 31. The liquid storage channel 31 forms a negative pressure, and the oil in the liquid inlet channel 14 is drawn into the liquid storage channel 31. During the above-mentioned operation, the indicator rod 60 slides back and forth in the left and right direction in the sliding cavity 13, and the right end of the indicator rod 60 continuously enters and exits the base 10, so that the indicator device operates smoothly.

[0047] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
