Description

Technical Field

[0001] The present invention relates to the technical field of atomizer cores, and in particular to a porous ceramic high-efficiency atomizer core flow guide structure. Background Art

[0002] The basic principle of ceramic atomizer core is to convert liquid into fine droplets through high-frequency oscillation to form inhalable aerosol or gas. The ceramic material used can withstand higher temperatures without deformation or damage, and its poor thermal conductivity can well avoid local overheating. It has strong corrosion resistance and durability, so ceramic atomizer core has gradually replaced the traditional metal atomizer core.

[0003] However, the ceramic atomizer core in the prior art usually uses external airflow to move toward the center, impacting the liquid flowing in the center to make it oscillate and form droplets. However, in this method, the airflow has an uneven effect on the liquid when impacting it, resulting in uneven liquid atomization and heating process, making it difficult for some liquids to evaporate and decompose quickly, and the sprayed atomized gas is unevenly distributed. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that the ceramic atomization core in the prior art usually uses the external airflow to move toward the center, impacts the liquid flowing in the center to make it oscillate and form droplets, but in this way the airflow has an uneven effect on the liquid when impacting it, resulting in uneven liquid atomization and heating process, part of the liquid is difficult to evaporate and decompose quickly, and the sprayed atomized gas is unevenly distributed. A porous ceramic high-efficiency atomization core guide structure is now provided.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a porous ceramic high-efficiency atomizer core flow guide structure, comprising an atomizer core body and a sleeve assembly sleeved outside the atomizer core body;

[0006] An inlet flow channel and a liquid inlet flow channel are formed inside the sleeve assembly;

[0007] A spiral pipe and a plurality of direct current pipes arranged circumferentially are formed inside the atomizer core body. The spiral pipe extends axially along the atomizer core body and is connected to the liquid inlet channel. The direct current pipe connects the inlet channel and the spiral pipe, and each direct current pipe penetrates the spiral pipe axially, so that the gas flowing in a straight line in the direct current pipe and the liquid flowing in a spiral direction into the spiral pipe impact each other to form droplets.

[0008] Furthermore, the sleeve assembly includes a sleeve body and a liquid inlet ring, the liquid inlet ring includes a first diverter ring which is sleeved on the outside of the sleeve body and has a liquid inlet, and a second diverter ring located between the sleeve body and the atomizer core body, and a plurality of connecting pipes are connected between the first diverter ring and the second diverter ring.

[0009] Furthermore, a focusing cover is fixed on the top of the atomizer core body, which includes an open cover with an open top and a larger upper and smaller lower structure, and a protruding portion located inside the open cover and with an arched structure, and the end of the direct current pipe away from the spiral pipe passes through the protruding portion.

[0010] Furthermore, a sealing component for opening or sealing the liquid inlet is installed on the liquid inlet.

[0011] Furthermore, the sealing assembly includes a liquid inlet mechanism fixed on the liquid inlet port and a sealing mechanism slidably arranged inside the liquid inlet mechanism. The bottom of the sealing mechanism is sealed and its peripheral wall is provided with a plurality of liquid outlet holes radially penetrating therethrough. When the liquid outlet holes are in contact with the inner peripheral wall of the liquid inlet mechanism, the liquid inlet mechanism is in a sealed state. When there is a gap between the liquid outlet holes and the inner peripheral wall of the liquid inlet mechanism to form a flow channel, the liquid inlet mechanism is in a conducting state.

[0012] Furthermore, the sealing mechanism protrudes radially to form a slider, the liquid inlet mechanism is provided with a sliding groove for the sliding of the slider, and the sliding groove includes a circumferential locking groove and an axial unlocking groove that are interconnected, and a torsion spring is provided between the liquid inlet mechanism and the sealing mechanism for confining the slider in the circumferential locking groove.

[0013] Furthermore, the liquid inlet mechanism includes a liquid inlet pipe and a receiving tube fixedly mounted on the outside of the liquid inlet pipe, with a lower receiving groove formed therebetween; the sealing mechanism includes a sealing tube slidably arranged on the inner side of the liquid inlet pipe and a sliding tube fixedly mounted on the outside of the sealing tube, with an upper receiving groove formed therebetween; a receiving cavity for installing a torsion spring is formed between the upper receiving groove and the lower receiving groove.

[0014] Furthermore, an air intake pipe is provided on the top of the sleeve assembly, and a plurality of guide vanes are fixed to the inner peripheral wall of the air intake pipe.

[0015] Furthermore, a heating mechanism is provided at the bottom of the atomizing core, which includes a heating cover with a plurality of atomizing spray holes, a heat-conducting ring fixed to the inner wall of the heating cover, and a heat-conducting wire connected to the heat-conducting ring.

[0016] Furthermore, the outer peripheral wall of the sleeve body is recessed to form a first fixing groove for the first diverter ring to be inserted into, and the outer peripheral wall of the atomizer core body is recessed to form a second fixing groove for the second diverter ring to be inserted into.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention utilizes a staggered flow-guiding design of spiral pipes and direct current pipes, where the direct current airflow drives the spiral liquid flow to impact and oscillate to form smaller droplets. Combined with the flow guidance of the guide plate and the flow focusing of the focusing hood, the airflow enters the direct current pipe and is distributed relatively evenly and concentratedly. Compared with the method of diverting the gas to impact the liquid, it ensures to a certain extent that the liquid is fully impacted by the airflow, and the droplets formed are relatively uniform, thus avoiding the occurrence of uneven droplet sizes during subsequent heating.

[0019] 2. By setting up a heating mechanism and utilizing the heat conduction effect of the heat conducting wire and the heat conducting ring, the external heat is conducted into the surface of the heating cover. The high-temperature heating cover heats the droplets in the atomizing nozzle to ensure that the droplets evaporate quickly to form atomized gas. At the same time, the outlet hole utilizes the dispersed airflow in the air inlet pipe to drive the atomized gas to spray out, further improving the practicality of the device.

[0020] 3. By setting up the sealing component, the elastic deformation of the torsion spring is utilized. When installing the device, the compressed torsion spring drives the slide tube and the sealing tube to unseal the liquid outlet hole in the sealed state to facilitate the flow of liquid. When the infusion pipeline needs to be removed, the elastic reset of the torsion spring drives the liquid outlet hole to seal, preventing external dust and other impurities from passing through the liquid inlet pipe, ensuring the subsequent smooth operation of the device.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention, and directions and references (e.g., up, down, left, right, etc.) may only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not to be taken in a limiting sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, a porous ceramic high-efficiency atomizer core flow guide structure includes an atomizer core body 2 and a sleeve assembly 1 sleeved outside the atomizer core body 2;

[0038] The sleeve assembly 1 has an inlet flow channel and a liquid inlet flow channel formed inside;

[0039] A spiral pipe 201 and a plurality of direct current pipes 202 arranged circumferentially are formed inside the atomizer core body 2. The spiral pipe 201 extends axially along the atomizer core body 2 and is connected to the liquid inlet channel through a curved pipe 203. The direct current pipe 202 connects the inlet channel and the spiral pipe 201, and each direct current pipe 202 penetrates the spiral pipe 201 axially, so that the liquid flowing in a straight line in the direct current pipe 202 and the liquid flowing in a spiral direction into the spiral pipe 201 impact each other to form small droplets.

[0040] When in use, the gas enters the direct current pipe 202 through the inlet flow channel, and the liquid enters the liquid flow channel and the curved pipe 203 in turn and enters the spiral pipe 201. Through the staggered diversion design of the spiral pipe 201 and the direct current pipe 202, the direct current airflow drives the spiral liquid flow to impact and oscillate to form smaller droplets. Because in the spiral liquid flow and direct current airflow system, the flow field presents a relatively regular distribution, the rotational characteristics of the spiral liquid flow make its interaction with the direct current airflow more orderly, and the velocity and pressure distribution are more continuous and smooth in space, providing a stable dynamic basis for the generation of uniform droplets; and the direct current pipe 202 runs through the spiral pipe 201, so in the process of the liquid passing through the spiral pipe 201, the liquid and gas will continue to impact each other, ensuring that the liquid is fully impacted by the airflow while the formed droplets are relatively uniform, avoiding the occurrence of uneven droplet size during subsequent heating.

[0041] In some examples, such as Figure 3 and Figure 4 As shown, the sleeve assembly 1 includes a sleeve body 101 and a liquid inlet ring 102, the liquid inlet ring 102 includes a first diverter ring 1021 sleeved outside the sleeve body 101 and having a liquid inlet, and a second diverter ring 1022 located between the sleeve body 101 and the atomizer core, the first diverter ring 1021 is located outside the second diverter ring 1022, and a plurality of radially extending connecting pipes 1023 are connected between the first diverter ring 1021 and the second diverter ring 1022;

[0042] A first diverter cavity is formed inside the first diverter ring 1021, a second diverter cavity is formed inside the second diverter ring 1022, and both ends of the connecting pipe 1023 are respectively connected to the first diverter cavity and the second diverter cavity; a plurality of through holes are radially penetrated through the sleeve body 101, and the plurality of through holes correspond one-to-one to the plurality of connecting pipes 1023, and each connecting pipe 1023 passes through its corresponding through hole; the liquid enters the first diverter cavity from the liquid inlet and then enters each connecting pipe 1023 to form a primary diversion, and then the liquid in each connecting pipe 1023 converges into the second diverter cavity and enters each direct current pipe 202 to form a secondary diversion.

[0043] In some examples, a focusing cover 204 is fixed on the top of the atomizer core body 2, which includes an open cover 2041 with an open top and a larger upper and smaller lower structure, and a protrusion 2042 located on the inner side of the open cover 2041 and having an arched structure. The protrusion 2042 is preferably spherical. The end of the direct current pipe 202 away from the spiral pipe 201 passes through the protrusion 2042. After the gas enters from the inlet flow channel, it is first focused by the focusing cover 204, so that the airflow entering the direct current pipe 202 is relatively evenly and concentrated.

[0044] In some examples, a sealing component 4 for opening or sealing the liquid inlet is installed on the liquid inlet. When the atomizer core body 2 is in a working state, the liquid inlet is opened to allow liquid to enter. When the atomizer core body 2 is in a non-working state, the sealing component 4 blocks the liquid inlet to prevent external dust and other impurities from entering the device through the liquid inlet, thereby ensuring the subsequent smooth operation of the device.

[0045] In some examples, the sealing assembly 4 includes a liquid inlet mechanism 401 fixed on the liquid inlet and a sealing mechanism 402 slidably disposed inside the liquid inlet mechanism 401, the bottom of the sealing mechanism 402 is blocked and a plurality of liquid outlet holes 4021 radially penetrating the sealing mechanism 402 are provided on its peripheral wall, the liquid inlet mechanism 401 includes equal diameter sections and flared sections distributed up and down, and the flared section is a structure with a small upper portion and a large lower portion;

[0046] In the initial state, the liquid outlet hole 4021 on the sealing mechanism 402 is in contact with the inner circumferential wall of the equal diameter section of the liquid inlet mechanism 401, and impurities entering the sealing mechanism 402 cannot enter the liquid inlet mechanism 401 through the liquid outlet hole 4021. At this time, the liquid inlet mechanism 401 is blocked;

[0047] When the sealing mechanism 402 is driven to move downward, the liquid outlet hole 4021 on the sealing mechanism 402 is separated from the equal-diameter section of the liquid inlet mechanism 401 and enters the flared section. There is a gap between the liquid outlet hole 4021 and the inner circumferential wall of the flared section to form a flow channel. The liquid entering the sealing mechanism 402 can enter the liquid inlet mechanism 401 through the liquid outlet hole 4021 and the above-mentioned flow channel in turn, and then enter the first diversion ring 1021 through the liquid inlet.

[0048] In some examples, the sealing mechanism 402 is radially protruding to form a slider 4022, the number of which may be but is not limited to one, two, or three, and the sliders 4022 are spaced apart along the circumference of the sealing mechanism 402;

[0049] The liquid inlet mechanism 401 is provided with a slide groove for the slider 4022 to slide, the number of the slide grooves corresponds to the number of the sliders 4022, and each slider 4022 slides in its corresponding slide groove, the slide groove includes a circumferential locking groove 4011 and an axial unlocking groove 4012 that are interconnected, and a torsion spring 403 is provided between the liquid inlet mechanism 401 and the sealing mechanism 402 for confining the slider 4022 in the circumferential locking groove 4011;

[0050] In the initial state, the slider 4022 is confined in the circumferential locking groove 4011 under the elastic force of the torsion spring 403. At this time, the sealing mechanism 402 and the liquid inlet mechanism 401 are axially locked, and the sealing mechanism 402 cannot slide up and down. At this time, the liquid inlet mechanism 401 is blocked;

[0051] When the force of the torsion spring 403 is overcome and the sealing mechanism 402 is driven to rotate, the slider 4022 enters the axial unlocking groove 4012 from the circumferential locking groove 4011, and then drives the sealing component 4 to move downward to expose the liquid outlet 4021 in the sealed state. At this time, the liquid inlet mechanism 401 is in a conductive state.

[0052] In some examples, the liquid inlet mechanism 401 includes a liquid inlet pipe 4013 and a receiving tube 4014 fixedly mounted on the outside of the liquid inlet pipe 4013, with a lower receiving groove formed therebetween, and the sealing mechanism 402 includes a sealing tube 4023 slidably arranged on the inner side of the liquid inlet pipe 4013 and a sliding tube 4024 fixedly mounted on the outside of the sealing tube 4023, with an upper receiving groove formed therebetween, and a receiving cavity for installing the torsion spring 403 is formed between the upper receiving groove and the lower receiving groove.

[0053] First, the output liquid pipeline is fixedly connected to the top of the slide 4024, and the slide 4024 is driven to rotate, so that the slide 4024 drives the slider 4022 from the circumferential locking groove 4011 to the axial unlocking groove 4012. At this time, the torsion spring 403 is elastically deformed by the rotation force of the slide 4024, and then the slide 4024 is pressed to drive the sealing tube 4023 to slide in the liquid inlet tube 4013, and the liquid outlet hole 4021 enters the expanded section from the equal diameter section of the liquid inlet tube 4013 to expose the liquid outlet hole 4021 to conduct the liquid, and the liquid enters the liquid outlet hole 4021 and the liquid inlet tube 4013 in turn. The first diversion chamber is now subjected to the pressing force of the slide 4024, so that the torsion spring 403 is further elastically compressed. After the output liquid pipeline is fixed, the torsion spring 403 is always in a compressed deformation state, which facilitates the liquid to enter the liquid inlet pipe 4013. When the device needs to be removed from the sprayer, the fixed output liquid pipeline can be removed, and the elastic reset of the torsion spring 403 drives the slide 4024 and the sealing tube 4023 to slide upward to seal the liquid outlet 4021, so as to prevent dust and other debris from entering the device through the liquid inlet pipe 4013 and causing blockage when the device is in a dismantled state and contacts the outside world.

[0054] In some examples, an air intake pipe 1012 is provided on the top of the sleeve assembly 1 , a plurality of guide vanes 1013 are fixed to the inner wall of the air intake pipe 1012 , and the above-mentioned air intake flow channel is formed inside the air intake pipe 1012 .

[0055] In some examples, a heating mechanism 3 is provided at the bottom of the atomizing core, which includes a heating cover 301 with a plurality of atomizing spray holes 302, a heat-conducting ring 303 fixed to the inner circumferential wall of the heating cover 301, and a heat-conducting wire 304 connected to the heat-conducting ring 303, the heat-conducting wire 304 passes through the sleeve assembly 1 and is fixedly connected to the sleeve assembly 1, the inner circumferential wall of the sleeve assembly 1 is fixedly connected to the outer circumferential wall of the heating cover 301, and the bottom wall of the sleeve assembly 1 is provided with a plurality of air outlet holes 305;

[0056] The heat conducting wire 304 is connected to the heating device, and the heat conducting effect of the heat conducting wire 304 and the heat conducting ring 303 is utilized to conduct the external heat into the surface of the heating cover 301. The high-temperature heating cover 301 heats the droplets in the atomizing nozzle 302 to evaporate them to form atomized gas. While ensuring that the droplets evaporate quickly to form atomized gas, the air outlet 305 cooperates with the dispersed airflow in the air inlet pipe 1012 to drive the atomized gas to spray out, thereby further improving the practicability of the device.

[0057] In some examples, the outer peripheral wall of the sleeve body 101 is recessed to form a first fixing groove 1011 for the first diverter ring 1021 to be inserted into, and the outer peripheral wall of the atomizer core body 2 is recessed to form a second fixing groove 205 for the second diverter ring 1022 to be inserted into. The first fixing groove 1011 and the second fixing groove 205 are both annular grooves, and the first diverter ring 1021 and the second diverter ring 1022 can be fixed respectively through the first fixing groove 1011 and the second fixing groove 205.

[0058] Working principle:

[0059] First, the output liquid pipeline is fixedly connected to the top of the slide cylinder 4024, and the slide cylinder 4024 is driven to rotate, so that the slide cylinder 4024 drives the slider 4022 from the circumferential locking groove 4011 to the axial unlocking groove 4012. At this time, the torsion spring 403 is elastically deformed by the rotation force of the slide cylinder 4024, and then the slide cylinder 4024 is pressed to drive the sealing tube 4023 to slide in the liquid inlet tube 4013, and the liquid outlet hole 4021 enters the expanded section from the equal diameter section of the liquid inlet tube 4013 to expose the liquid outlet hole 4021 to conduct the liquid, and the liquid enters the first diverter ring 1021 through the liquid outlet hole 4021 and the liquid inlet tube 4013 in turn. The liquid in the first diverter ring 1021 is diverted into the second diverter ring 1022 through the connecting tube 1023, and then diverted by the second diverter ring 1022 into a plurality of curved pipes 203 to bend and flow to the spiral pipe 201, so that the liquid flow direction is distributed in a spiral shape;

[0060] At the same time, the airflow is blown into the sleeve assembly 1 through the air inlet pipe 1012, and the gas is spirally guided by a plurality of guide plates 1013 through the air inlet pipe 1012, so that the airflow is guided into a spiral shape and rotates into the sleeve, which can improve the airflow concentration to a certain extent, and then the airflow passes through the focusing cover 204 to gather most of the central airflow and rush to the direct current pipe 202, and the airflow is diverted into the atomizer core body 2 through a plurality of direct current pipes 202, and the airflow is straight at this time; a plurality of direct current pipes 202 staggered through a plurality of spiral pipes 201, and the spiral guiding liquid is staggered with the direct current airflow, so that the straight airflow and the spiral liquid flow are staggered and impacted with each other to form relatively small droplets, ensuring that the liquid is fully impacted by the airflow while the droplets are relatively uniformly formed, and the liquid and the gas impact each other to form small droplets and then form a spray, and cooperate with the heating mechanism 3 to complete the atomization process, and a small amount of airflow that enters the sleeve from the air inlet pipe 1012 and does not reach the focusing cover 204 is discharged through the air outlet 305, which is convenient for the synchronous blowing of the gas heated and atomized by the heating mechanism 3.
