Description

Technical Field

[0001] The utility model relates to the field of nozzle maintenance of an aerosol generator, in particular to a cleaning device for an atomizing nozzle of an aerosol generator and an aerosol generator. Background Art

[0002] Existing aerosol generator nozzles typically utilize the Venturi effect, drawing a mixed solution containing fixed particles into the nozzle through negative pressure. After mixing with compressed air, a high-speed airflow is generated through a small hole, dispersing the liquid into small particles. This airflow is then subjected to high-temperature dehumidification treatment to produce an aerosol of a specified concentration. During the development of this utility model, the applicant discovered that the prior art suffers from at least the following problems:

[0003] During use, particles in the solution generated by the wet method or the particles in the dry method are likely to accumulate at the inlet and gradually block the inlet. Utility Model Content

[0004] The embodiment of the utility model provides a cleaning device for the atomizing nozzle of an aerosol generator and an aerosol generator, which can solve the technical problem in the prior art that "during use, particulate matter in the solution generated by the wet method or particulate matter in the dry method is prone to accumulation at the inlet and gradually block the inlet."

[0005] To achieve the above-mentioned purpose, on the one hand, an embodiment of the present invention provides a cleaning device for an atomizing nozzle of an aerosol generator, wherein the atomizing nozzle has a gas channel that runs transversely therethrough, and the atomizing nozzle also has a particle channel that is angled with and connected to the gas channel, wherein a first end of the gas channel has an air inlet, and a second end of the gas channel is connected to a particle outlet of the particle channel.

[0006] The atomizing nozzle further comprises a mixing channel connected to the particle outlet and the second end of the gas channel, wherein the mixing channel comprises an outlet for spraying a mixture of the mixed gas and particles.

[0007] The atomizing nozzle is connected to a generating cavity, and the generating cavity includes an input channel for the mixed gas and particulate matter to enter the generating cavity, the input channel has a cavity inlet, and the mixture outlet is connected to the cavity inlet;

[0008] The cleaning device is used to clean the particles on the particle channel and the mixing channel of the atomizing nozzle, and the cleaning device includes:

[0009] A cylindrical valve core is provided at the inlet side of the cavity and enters into the input channel. There is an angle between the cylindrical valve core and the input channel. When the cylindrical valve core rotates to a first position, the gas channel and the input channel are connected to form a passage. When the cylindrical valve core rotates to a second position, the gas channel and the input channel are disconnected and no passage can be formed.

[0010] On the other hand, an embodiment of the present invention provides an aerosol generator, comprising: an atomizing nozzle having a transversely extending gas channel, the atomizing nozzle also having a particle channel that is angled and connected to the gas channel, the first end of the gas channel having an air inlet, the second end of the gas channel being connected to the particle outlet of the particle channel,

[0011] The atomizing nozzle further comprises a mixing channel connected to the particle outlet and the second end of the gas channel, wherein the mixing channel comprises an outlet for spraying a mixture of the mixed gas and particles.

[0012] The atomizing nozzle is connected to a generating cavity, and the generating cavity includes an input channel for the mixed gas and particulate matter to enter the generating cavity, the input channel has a cavity inlet, and the mixture outlet is connected to the cavity inlet;

[0013] The aerosol generator further comprises the aforementioned cleaning device for the atomizing nozzle of the aerosol generator.

[0014] The above technical solution has the following beneficial effects: when working, the cylindrical valve core rotates to the first position, the gas channel and the input channel are connected to form a passage, compressed air is input into the gas channel from the air inlet, and the fixed particulate matter or the fixed particulate matter mixed solution is sucked in through the particulate matter channel. After the compressed air contracts through the pipeline of the gas channel, a high-speed airflow is generated through the small holes. Because of the negative pressure generated by the Venturi effect, the fixed particulate matter or the fixed particulate matter mixed solution is sucked into the mixing channel when passing through the particulate matter channel, and after mixing with the air, it is ejected at high speed from the mixture outlet, enters the input channel, and further enters the generating cavity.

[0015] When the atomizing nozzle stops working or is periodically cleaned of the fixed particles or the fixed particle mixed solution, the cylindrical valve core rotates to the second position, stopping the fixed particles or the fixed particle mixed solution from being drawn in through the particle channel, but continuing to input compressed air from the air inlet into the gas channel. Because the cylindrical valve core disconnects the gas channel from the input channel and prevents a passage from being formed, the compressed air naturally flows into the particle channel with a low negative pressure. The continuous compressed air can blow the fixed particles or the fixed particle mixed solution in the particle channel back into its original container or cavity, thereby cleaning the particle channel and preventing the particle channel from becoming clogged after use. The utility model can achieve automatic cleaning of the aerosol particle channel, especially the inlet, of the aerosol in the aerosol generating device, greatly reducing the phenomenon of blockage of the particle channel, especially the inlet, in the aerosol generating device, reducing manual maintenance time and cost, and providing the greatest guarantee for the subsequent long-term stable operation of the aerosol generating device. It can also achieve dredging of the particle channel, especially the inlet, after it becomes clogged. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1 、 Figure 3 and Figure 4 As shown, in combination with an embodiment of the present utility model, a cleaning device for an atomizing nozzle of an aerosol generator is provided, the atomizing nozzle 4 is provided with a transversely running gas channel 6, the atomizing nozzle 4 is also provided with a particle channel 5 which is at an angle to and connected to the gas channel 6, the first end of the gas channel 6 is provided with an air inlet 61, the second end of the gas channel 6 is connected to the particle outlet 51 of the particle channel 5, the atomizing nozzle 4 is also provided with a mixing channel 20 connected to the particle outlet 51 and the second end of the gas channel 6, the mixing channel 20 has a mixture outlet 201 for spraying out the mixed gas and particles, the atomizing nozzle 4 is connected to a generating cavity 7, the generating cavity 7 includes an input channel 9 for the mixed gas and particles to enter the generating cavity 7, the input channel 9 has a cavity inlet 91, and the mixture outlet 201 is connected to the cavity inlet 91; the cleaning device is used to clean the particles on the particle channel 5 of the atomizing nozzle 4 and the mixing channel 20.

[0026] The cleaning device includes: a cylindrical valve core 1, which is arranged on the side of the cavity inlet 91 and enters into the input channel 9. There is an angle between the cylindrical valve core 1 and the input channel 9. When the cylindrical valve core 1 rotates to a first position, the gas channel 6 and the input channel 9 are connected to form a passage. When the cylindrical valve core 1 rotates to a second position, the gas channel 6 and the input channel 9 are disconnected and no passage can be formed.

[0027] During operation, the cylindrical valve core 1 rotates to the first position, the gas channel 6 is connected with the input channel 9 to form a passage, and compressed air is input into the gas channel 6 from the air inlet 61, and the fixed particulate matter or the fixed particulate matter mixed solution is sucked in through the particulate matter channel 5. After the compressed air contracts through the pipeline of the gas channel 6, a high-speed airflow is generated through the small holes. Because of the negative pressure generated by the Venturi effect, the fixed particulate matter or the fixed particulate matter mixed solution is sucked into the mixing channel 20 when passing through the particulate matter channel 5, and after mixing with the air, it is ejected at high speed from the mixture outlet 201, enters the input channel 9, and further enters the generating cavity 7.

[0028] When the atomizing nozzle 4 is stopped or the fixed particles or the fixed particle mixed solution are periodically cleaned, the cylindrical valve core 1 rotates to the second position, stopping the fixed particles or the fixed particle mixed solution from being drawn through the particle channel 5, but continuing to input compressed air from the air inlet 61 into the gas channel 6. Because the cylindrical valve core 1 disconnects the gas channel 6 from the input channel 9, preventing a passage, the compressed air naturally flows into the particle channel 5, where the negative pressure is low. The continuous flow of compressed air can blow the fixed particles or the fixed particle mixed solution in the particle channel 5 back into its original container or cavity, thereby cleaning the particle channel 5 and preventing the particle channel 5 from becoming clogged after use. The present utility model can achieve automatic cleaning of the aerosol particle channel 5, especially its inlet, in the aerosol generating device, greatly reducing the phenomenon of blockage in the particle channel 5, especially its inlet, in the aerosol generating device, reducing manual maintenance time and cost, and providing the greatest guarantee for the subsequent long-term stable operation of the aerosol generating device. Moreover, even if the particle channel 5, especially its inlet, is clogged, it can be cleared.

[0029] Preferably, if Figure 2 As shown, the angle between the cylindrical valve core 1 and the input channel 9 is ninety degrees, and the cylindrical valve core 1 has a through hole 2, which is perpendicular to the axis of the cylindrical valve core 1. When the cylindrical valve core 1 rotates to the first position, the through hole 2, the gas channel 6 and the input channel 9 are connected to form a passage. The second position is perpendicular to the first position. When the cylindrical valve core 1 rotates to the second position, the through hole 2 is perpendicular to the input channel 9, and the gas channel 6 and the input channel 9 are disconnected and cannot form a passage.

[0030] By rotating the cylindrical valve core 1, the position of the through hole 2 is changed to realize the connection and closing of the gas channel 6 and the input channel 9, thereby meeting the normal working requirements and cleaning requirements of the atomizing nozzle 4.

[0031] Preferably, if Figure 4As shown, the cylindrical valve core 1 is arranged in the cylindrical valve hole 8 on the cavity wall of the generating cavity 7, and the cylindrical valve core 1 has a first end, and the first end of the cylindrical valve core 1 contacts the bottom of the cylindrical valve hole 8, and the cylindrical valve core 1 has a second end, and the second end of the cylindrical valve core 1 is exposed outside the cylindrical valve hole 8, and the cylindrical valve core 1 is rotated to the first position or the second position through the second end of the cylindrical valve core 1.

[0032] Preferably, if Figure 1 and Figure 2 As shown, the surface of the cylindrical valve core 1 is provided with an annular groove 11, which is provided between the second end of the cylindrical valve core 1 and the through hole 2. The cleaning device also includes a sealing ring, which is provided in the annular groove 11 and is in sealing contact with the inner wall of the cylindrical valve hole 8, making the input channel 9 a sealed channel. Then, the fixed particulate matter or the fixed particulate matter mixed solution is sucked into the mixing channel 20 and can enter the input channel 9 after mixing with air. Preferably, two parallel annular grooves 11 are provided, and two matching sealing rings are also provided to improve the sealing performance.

[0033] Preferably, if Figure 1 and Figure 2 As shown, a flange 3 is provided on the second end of the cylindrical valve core 1, and the cleaning device also includes a stop switch 10, which is installed on the flange 3. The stop switch 10 is used to automatically stop and lock the cylindrical valve core 1 when it is rotated to the first position. The stop switch 10 is used to automatically stop and lock the cylindrical valve core 1 when it is rotated to the second position, and the cylindrical valve core 1 can be easily rotated to the first position or the second position.

[0034] Preferably, if Figure 1 As shown, the stop switch 10 is a steering gear, which is a finished product. The steering gear can be controlled by a program. When the particle passage 5, especially its inlet, is blocked, a programmed one-button automatic unblocking function can be realized, thereby realizing functions such as automatic maintenance. In addition, the steering gear is easy to purchase and easy to operate.

[0035] Preferably, if Figure 1 As shown, a sealing cover is provided on the cylindrical valve hole 8 at the second end of the cylindrical valve core 1.

[0036] like Figure 1 、 Figure 3 and Figure 4As shown, in combination with an embodiment of the utility model, an aerosol generator is provided, comprising: an atomizing nozzle 4 having a transversely extending gas channel 6, the atomizing nozzle 4 also having a particle channel 5 which is at an angle to and connected to the gas channel 6, the first end of the gas channel 6 having an air inlet 61, the second end of the gas channel 6 being connected to the particle outlet 51 of the particle channel 5, the atomizing nozzle 4 also having a mixing channel 20 connected to the particle outlet 51 and the second end of the gas channel 6, the mixing channel 20 having a mixture outlet 201 for spraying out the mixed gas and particles, the atomizing nozzle 4 being connected to a generating cavity 7, the generating cavity 7 including an input channel 9 for the mixed gas and particles to enter the generating cavity 7, the input channel 9 having a cavity inlet 91, the mixture outlet 201 being connected to the cavity inlet 91; the aerosol generator also comprises a cleaning device for the atomizing nozzle of any of the aforementioned aerosol generators. During operation, the cylindrical valve core 1 rotates to the first position, the gas channel 6 is connected with the input channel 9 to form a passage, and compressed air is input into the gas channel 6 from the air inlet 61, and the fixed particulate matter or the fixed particulate matter mixed solution is sucked in through the particulate matter channel 5. After the compressed air contracts through the pipeline of the gas channel 6, a high-speed airflow is generated through the small holes. Because of the negative pressure generated by the Venturi effect, the fixed particulate matter or the fixed particulate matter mixed solution is sucked into the mixing channel 20 when passing through the particulate matter channel 5, and after mixing with the air, it is ejected at high speed from the mixture outlet 201, enters the input channel 9, and further enters the generating cavity 7.

[0037] When the work is stopped or the fixed particulate matter or fixed particulate matter mixed solution in the atomizing nozzle 4 is cleaned regularly, the cylindrical valve core 1 rotates to the second position, stops sucking the fixed particulate matter or fixed particulate matter mixed solution through the particulate matter channel 5, but continues to input compressed air into the gas channel 6 from the air inlet 61. Because the cylindrical valve core 1 disconnects the gas channel 6 from the input channel 9 and no passage is formed, the compressed air will naturally flow to the particulate matter channel 5 with low negative pressure. The continuous compressed air can blow the fixed particulate matter or fixed particulate matter mixed solution in the particulate matter channel 5 back into its original container or cavity, thereby cleaning the particulate matter channel 5 and preventing the particulate matter channel 5 from being blocked after use.

[0038] Preferably, if Figure 1As shown, when aerosols are generated by a wet method, the generating chamber 7 has a small droplet outlet 71 located at the top and a large droplet outlet 72 located at the bottom. During operation, the atomizing nozzle 4 sprays a fixed particle mixed solution into the generating chamber 7 through the input channel 9. The large-sized fixed particle mixed solution naturally settles and flows out through the large droplet outlet 72, while the small-sized fixed particle mixed solution flows upward with the airflow through the small droplet outlet 71 and undergoes high-temperature dehumidification treatment to achieve separation of the large and small fixed particle mixed solutions. If aerosols are generated by a dry method, the solution flows directly out through the small droplet outlet 71.
