Description

Technical Field

[0001] The invention relates to an atomization system, in particular to an atomization system using a microporous atomization sheet for atomization. Background Art

[0002] At present, the commonly used atomizers are divided into piezoelectric ceramic atomizers and microporous atomizers. The piezoelectric ceramic atomizer needs to be placed in the liquid and generate high-frequency resonance under the control of the drive control circuit to break up the liquid water molecule structure and produce naturally flowing water mist. The working environment and atomization principle of the microporous atomizer are completely different. There are many conical micropores in the central area of ​​the microporous atomizer, and the conical micropores play the role of storing liquid. When working, the inner side of the microporous atomizer is in contact with the water in the liquid container, and the outer side is exposed to the external space. In this way, the conical micropores are connected to the liquid container and the external space. When working, driven by the high-frequency circuit, the microporous atomizer high-speed bending vibration ejects the liquid stored in the conical micropores. The microporous atomizer undergoes two stages of ejection and rehydration for each vibration cycle. The two stages of ejection and rehydration are repeated, so that the liquid is ejected from the micropores of the microporous atomizer to form mist.

[0003] The microporous atomizing sheet is often used in the side spraying equipment of the reverse pouring type. For example, the bottled humidifier with patent number 201610876935.5 proposed by the patentee on January 9, 2016 includes a base, a microporous atomizing sheet arranged on the base, and a controller electrically connected to the microporous atomizing sheet; a liquid storage channel is arranged on the base, and the microporous atomizing sheet is used to atomize the liquid in the liquid storage channel, characterized in that the liquid storage channel is roughly L-shaped and includes a vertical liquid storage channel and a horizontal liquid storage channel, and a bottle body connecting mechanism is also arranged on the base, and the bottle body connecting mechanism can be detachably connected to the inverted liquid storage bottle and make the bottle mouth of the liquid storage bottle sealed and docked with the liquid inlet of the vertical liquid storage channel; the microporous atomizing sheet is detachably connected to the liquid outlet of the horizontal liquid storage channel. In a non-atomizing working state, when the liquid level in the liquid storage bottle is higher than the liquid level in the horizontal liquid storage channel, the inner hydraulic pressure of the microporous atomization sheet is often greater than the atmospheric pressure, causing the liquid in the horizontal liquid storage channel to be forced to leak out through the micropores of the microporous atomization sheet, forming a slow penetration phenomenon. Summary of the invention

[0004] In the face of the above technical problems, one of the inventive purposes of the present invention is to propose a technical solution that can be used to alleviate the above slow penetration phenomenon. In view of this, the present invention proposes an atomization system that uses a microporous atomization sheet for atomization, including an atomization body, the atomization body includes a microporous atomization sheet installed at a side position of the atomization body, a liquid cache space is arranged on the inner side of the microporous atomization sheet, and the microporous atomization sheet is used to atomize and spray the liquid in the liquid cache space, characterized in that an infusion channel is also arranged on the atomization body, the infusion channel is connected to the liquid cache space for providing the liquid to be atomized to the liquid cache space, and a control valve is provided on the infusion channel, and the control valve is used to open or close the infusion channel.

[0005] The side of the microporous atomizing sheet facing the external space is the outer side, and the opposite side is the inner side.

[0006] Among them, the infusion channel can transport external liquid outside the liquid cache space to the liquid cache space. For example, the liquid container to be discussed below can be selected as a liquid storage device for the external liquid. When the control valve opens the infusion channel, the external liquid will be transported to the liquid cache space through the infusion channel. At this time, if it is in a non-atomization working state, and when the liquid level of the external liquid is higher than the liquid level in the liquid cache space, the hydraulic pressure at the position of the microporous atomization sheet in the liquid cache space will increase, and the probability and amount of liquid leakage from the micropores of the microporous atomization sheet to the external space will be increased. When the control valve shuts off the infusion channel, the infusion channel stops providing the liquid to be atomized to the liquid cache space, and the liquid level height of the external liquid will not affect the hydraulic pressure at the position of the microporous atomization sheet in the liquid cache space, or the effect is very small.

[0007] According to the above technical scheme, compared with the prior art, the present invention can achieve at least one of the following beneficial technical effects: since the control valve is used to open or close the infusion channel, the control valve can be used to control the amount and time of the liquid to be atomized provided to the liquid cache space, so that it can better cooperate with the needs of the atomization work and provide the appropriate amount of liquid to the liquid cache space at the appropriate time. In addition, according to actual needs, the function of the control valve to shut off the infusion channel can be utilized. When the atomization system is in a non-atomization working state, the control valve is allowed to shut off the infusion channel, so that the hydraulic pressure at the position of the microporous atomization piece in the liquid cache space will not be affected by the liquid level height of the external liquid. The hydraulic pressure at the position of the microporous atomization piece in the liquid cache space is mainly determined by the liquid level height in the liquid cache space. Compared with the situation where the control valve is in an open state and the liquid level of the external liquid is higher than the liquid level in the liquid cache space, the hydraulic pressure at the position of the microporous atomization piece in the liquid cache space can be effectively reduced, which is conducive to making the hydraulic pressure at the position of the microporous atomization piece in the liquid cache space less than or close to the external atmospheric pressure, thereby reducing the probability and leakage amount of the liquid in the liquid cache space leaking from the micropores of the microporous atomization piece to the external space, and alleviating the occurrence of slow infiltration.

[0008] If the flow area of ​​the pipe in the infusion channel or the control valve is large enough, after the control valve opens the infusion channel, a small part of the air in the liquid cache space passes through the micropores of the microporous atomization sheet and is discharged to the external space, while most of the air can be discharged in time through the infusion channel and the pipe in the control valve, so that the liquid in the infusion channel can enter the liquid cache space in time for fluid replenishment. However, if the flow area of ​​the pipe in the infusion channel or the control valve is very small, the air in the liquid cache space cannot be discharged through the infusion channel and the pipe in the control valve, and the speed of discharge to the external space through the micropores of the microporous atomization sheet is very slow, the air pressure in the liquid cache space is very likely to prevent the liquid from entering the liquid cache space, so that the liquid cache space cannot get an appropriate amount of fluid replenishment. In order to solve the above technical problems, the present invention further proposes the following solution, in which an exhaust channel is also arranged on the atomization body, and the exhaust channel is connected to the liquid cache space for exhausting the air in the liquid cache space. In this way, the air in the liquid cache space can be discharged to the outside of the liquid cache space in time through the exhaust channel, so that the liquid in the infusion channel can smoothly enter the liquid cache space. This solution is suitable for solutions in which the flow area of ​​the infusion channel or the pipeline in the control valve is large or small.

[0009] A further technical solution may also include a liquid container, wherein a liquid storage cavity for containing the liquid to be atomized is arranged in the liquid container, and the liquid container is used to be detachably connected to the atomizing body and is located above the liquid cache space; when the liquid container is connected to the atomizing body, the infusion channel is connected to the liquid storage cavity of the liquid container so as to transport the liquid in the liquid storage cavity to the liquid cache space; the exhaust channel is connected to the upper space of the liquid in the liquid storage cavity so as to maintain an air pressure balance between the upper space of the liquid in the liquid storage cavity and the liquid cache space. According to the above technical solution, after the control valve opens the infusion channel, the liquid in the liquid storage cavity enters the liquid cache space through the infusion channel, and the air in the liquid cache space is discharged to the upper space of the liquid in the liquid storage cavity through the exhaust channel. In addition, when the atomization system topples over and part of the liquid in the liquid buffer space enters the exhaust channel, the exhaust channel can cause the liquid that has entered therein to flow back into the liquid storage cavity without leaking into the external space and wetting other parts.

[0010] A further technical solution may be that the liquid container is vertically mounted on the atomizing body so that the liquid level in the liquid container is higher than the liquid level in the liquid buffer space; and further includes an exhaust pipe, the exhaust pipe having a tube inner cavity, one end of the tube inner cavity of the exhaust pipe is connected to the exhaust channel, and the other end extends to the upper space of the liquid in the liquid storage cavity so that the upper space of the liquid in the liquid storage cavity is connected to the exhaust channel and the liquid buffer space through the tube inner cavity. According to the above technical solution, the exhaust pipe can be used to very conveniently realize the connection between the liquid buffer space and the upper space of the liquid in the liquid storage cavity.

[0011] A further technical solution may be that an annular transition ring is further provided between the atomizing body and the liquid container, the transition ring is provided with an annular groove, and the exhaust channel and the inner cavity of the tube are respectively connected to the groove cavity of the annular groove. According to the above technical solution, the annular groove has a certain extension length in the circumferential direction, and it can be a closed annular or open annular shape, and the groove cavity of the annular groove becomes an intermediate transition connection channel between the exhaust channel and the inner cavity of the tube, reducing the precision requirement for the alignment connection of the exhaust channel and the inner cavity of the tube.

[0012] A further technical solution may be that a sealing ring is provided between the two walls of the annular groove and the atomizing body, so as to reduce the leakage of liquid through the gap between the annular groove and the atomizing body.

[0013] A further technical solution may be that an annular transition ring is further provided between the atomizing body and the liquid container, an annular channel is formed between the transition ring and the atomizing body, and the exhaust channel and the tube lumen are respectively connected to the annular channel. According to the above technical solution, the annular channel has a certain extension length in the circumferential direction, and it can be a closed ring or an open ring. The annular channel becomes an intermediate transition connection channel between the exhaust channel and the tube lumen, reducing the precision requirements for the alignment connection between the exhaust channel and the tube lumen.

[0014] A further technical solution may be that the liquid container is screwed onto the atomizing body, and the cavity of the liquid container presses against the transition ring, so that the transition ring can be positioned by using the liquid container.

[0015] A further technical solution may be that the control valve is a solenoid valve.

[0016] In order to realize the automatic control of the microporous atomization sheet and the control valve, a further technical solution may also include a control device, wherein the microporous atomization sheet and the control valve are respectively connected to the control device by signal, and the control device is used to control the atomization work of the microporous atomization sheet and the work of the control valve. According to the above technical solution, the control device can be used to control the coordinated work of the microporous atomization sheet and the control valve. For example, the microporous atomization sheet can be controlled to work intermittently, and the control valve can be used to open the infusion channel to provide the liquid to be atomized to the liquid cache space when the microporous atomization sheet stops working, and the infusion channel is closed and the microporous atomization sheet is started after an appropriate amount of liquid to be atomized is stored in the liquid cache space. In this way, it is possible to provide the liquid to be atomized to the liquid cache space, and it is also possible to alleviate the slow penetration phenomenon caused by the infusion channel being normally open.

[0017] Since the present invention has the above characteristics and advantages, it can be applied to an atomization system that uses a microporous atomization sheet for atomization. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The structure of the atomization system using a microporous atomization sheet for atomization using the technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] As shown in the figure, the present invention proposes an atomization system that uses a microporous atomization sheet for atomization, including an atomization body 100, wherein the atomization body 100 includes a microporous atomization sheet 3 installed at a side position of the atomization body 100, and a liquid buffer space 21 is arranged on the inner side of the microporous atomization sheet 3. The microporous atomization sheet 3 is used to atomize and spray the liquid in the liquid buffer space 21. It is characterized in that an infusion channel (22, 41) is also arranged on the atomization body 100, and the infusion channel (22, 41) is connected to the liquid buffer space 21 for providing the liquid to be atomized to the liquid buffer space 21. A control valve 7 is provided on the infusion channel (22, 41), and the control valve 7 is used to open or close the infusion channel (22, 41).

[0023] The above technical solution will be further described below in conjunction with the accompanying drawings. Figure 1 and Figure 2As shown, the atomization system includes an atomization body 100 and a liquid container 200. The atomization body 100 includes an outer shell 1, a microporous atomization sheet 3 installed at a side position of the atomization body 100, an atomization sheet fixing seat 2 accommodated in the outer shell 1 for fixing the microporous atomization sheet 3, and a connector 4 for connecting the liquid container 200. A spray nozzle 11 is arranged on the outer shell 1, and the spray nozzle 11 is used to guide the atomized vapor sprayed by the microporous atomization sheet 3. A liquid buffer space 21 is arranged on the atomization sheet fixing seat 2, and the liquid buffer space 21 is arranged on the inner side of the microporous atomization sheet 3. An infusion channel 22 is also arranged on the atomization sheet fixing seat 2, and the infusion channel 22 is connected to the liquid buffer space 21. A concave cavity 40 is arranged on the connector 4, and a connecting thread 43 is arranged on the side wall of the concave cavity 40, and the connecting thread 43 is used to be threadedly connected with the liquid container 200. A liquid infusion channel 41 is provided on the bottom wall of the cavity 40. A liquid storage inner cavity 201 for storing liquid to be atomized is arranged in the liquid container 200. The liquid container 200 is used to be detachably connected to the connector 4 and vertically installed on the atomizing body 100. The liquid container 200 is located above the liquid buffer space 21, and the liquid level in the liquid container 200 is higher than the liquid level in the liquid buffer space 21. When the liquid container 200 is connected to the atomizing body 100, the liquid infusion channel (22, 41) communicates with the liquid storage inner cavity 201 of the liquid container 200 so as to transport the liquid in the liquid storage inner cavity 201 to the liquid buffer space 21. A control valve 7 is provided on the infusion channel (22, 41), and the control valve 7 is a solenoid valve. The control valve 7 includes an inlet channel 71 and an outlet channel 72. The inlet channel 71 is connected to the infusion channel 41, and the outlet channel 72 is connected to the infusion channel 22. A valve core 73 is provided at the intersection of the inlet channel 71 and the outlet channel 72. When the valve core 73 moves to the intersection of the inlet channel 71 and the outlet channel 72 and blocks the outlet channel 72, the liquid in the inlet channel 71 cannot enter the outlet channel 72. When the valve core 73 moves away from the intersection of the inlet channel 71 and the outlet channel 72 so that the inlet channel 71 is connected to the outlet channel 72, the liquid in the inlet channel 71 can enter the outlet channel 72.

[0024] According to the above technical solution, since the control valve 7 is used to open or close the infusion channel (22, 41), the control valve 7 can be used to control the amount and time of the liquid to be atomized provided to the liquid cache space 21, so as to better meet the needs of the atomization work and provide the appropriate amount of liquid to the liquid cache space 21 at the appropriate time. In addition, according to actual needs, the function of the control valve 7 to close the infusion channel (22, 41) can be utilized. When the atomization system is in a non-atomization working state, the control valve 7 is allowed to close the infusion channel (22, 41) so that the liquid-containing inner cavity 201 is not connected to the liquid cache space 21, and no communicating vessel is formed. The hydraulic pressure at the position of the microporous atomization sheet 3 in the liquid cache space 21 will not be affected by the liquid level height in the liquid-containing inner cavity 201, and the hydraulic pressure at the position of the microporous atomization sheet 3 in the liquid cache space 21 is mainly determined by the liquid buffer. The height of the liquid level in the storage space 21 is determined by the height of the liquid level in the storage space 21. Compared with the case where the infusion channel (22, 41) is connected to the liquid storage inner cavity 201 and the liquid level in the liquid storage inner cavity 201 is higher than the liquid level in the liquid cache space 21, the hydraulic pressure at the position of the microporous atomization sheet 3 in the liquid cache space 21 can be effectively reduced, which is beneficial for making the hydraulic pressure at the position of the microporous atomization sheet 3 in the liquid cache space 21 less than or close to the external atmospheric pressure, thereby reducing the probability and leakage amount of the liquid in the liquid cache space 21 leaking from the micropores of the microporous atomization sheet 3 to the external space, thereby alleviating the occurrence of slow penetration.

[0025] If the flow area of ​​the pipe in the infusion channel (22, 41) or the control valve 7 is large enough, after the control valve 7 opens the infusion channel (22, 41), a small part of the air in the liquid cache space 21 is discharged to the external space through the micropores of the microporous atomization sheet 3, and most of the air can be discharged in time through the infusion channel (22, 41) and the pipe in the control valve 7, so that the liquid in the infusion channel (22, 41) can enter the liquid cache space 21 in time for fluid replenishment. However, if the flow area of ​​the pipe in the infusion channel (22, 41) or the control valve 7 is very small, the air in the liquid cache space 21 cannot be discharged through the infusion channel (22, 41) and the pipe in the control valve, and the speed of discharge to the external space through the micropores of the microporous atomization sheet 3 is very slow, the air pressure in the liquid cache space 21 is very likely to prevent the liquid from entering the liquid cache space 21, so that the liquid cache space 21 cannot obtain an appropriate amount of fluid replenishment. In order to solve the above technical problems, further, an exhaust channel 23 is arranged on the atomizer body 100. In the present embodiment, the exhaust channel 23 is arranged on the atomizer plate fixing seat 2. The exhaust channel 23 is connected to the liquid cache space 21 to exhaust the air in the liquid cache space 21. The exhaust channel 23 is also connected to the upper space 202 of the liquid in the liquid-containing inner cavity 201 so that the air pressure balance is maintained between the upper space 202 of the liquid in the liquid-containing inner cavity 201 and the liquid cache space 21. According to the above technical solution, after the control valve 7 opens the infusion channel (22, 41), the liquid in the infusion channel (22, 41) enters the liquid cache space 21, and the air in the liquid cache space 21 is discharged into the upper space 202 of the liquid in the liquid-containing inner cavity 201 through the exhaust channel 23. In addition, when the atomization system topples over and part of the liquid in the liquid buffer space 21 enters the exhaust channel 23, the exhaust channel 23 can cause the liquid entering therein to flow back into the liquid storage cavity 201 without leaking into the external space and wetting other parts.

[0026] In order to achieve that the exhaust channel 23 is connected to the upper space 202 of the liquid in the liquid storage chamber 201, as shown in FIG. Figure 2As shown, an annular transition ring 5 is also provided between the atomizing body 100 and the liquid container 200. An outer sealing ring 61 and an inner sealing ring 62 provided in the inner ring space of the outer sealing ring 61 are provided between the cavity bottom wall of the connector 4 and the transition ring 5. The inner sealing ring 62 is arranged at intervals from the outer sealing ring 61 so as to form an annular channel 6 therebetween. An exhaust transition channel 42 is also provided on the connector 4, one end of the exhaust transition channel 42 is connected to the exhaust channel 23, and the other end is connected to the annular channel 6. The transition ring 5 is also provided with a connecting tube 51, on which an exhaust pipe 8 is detachably plugged, and the exhaust pipe 8 has a tube inner cavity 81, one end of the tube inner cavity 81 of the exhaust pipe 8 is connected to the annular channel 6 and thus connected to the exhaust channel 23, and the other end extends to the upper space 202 of the liquid in the liquid-containing inner cavity 201 so that the upper space 202 of the liquid in the liquid-containing inner cavity 201 is connected to the exhaust channel 23 and the liquid buffer space 21 through the tube inner cavity 81. According to the above technical solution, the exhaust pipe 8 can be used to very conveniently realize the communication between the exhaust channel 23 and the upper space 202 of the liquid in the liquid-containing inner cavity 201. In addition, the liquid container 200 is screwed on the atomizing body 100, and the cavity of the liquid container 200 presses the transition ring 5. In this way, the transition ring 5 can be positioned by using the liquid container 200, which is also conducive to enhancing the sealing between the transition ring 5 and the atomizing body 100.

[0027] In other embodiments, in order to realize that the exhaust channel 23 is connected to the upper space 202 of the liquid in the liquid storage inner cavity 201, other embodiments can also be adopted, and an annular transition ring 5 is further provided between the atomizing body 100 and the liquid storage container 200, and an annular groove is provided in the transition ring 5, and the exhaust channel 23 and the tube inner cavity 81 are respectively connected to the groove cavity of the annular groove. A sealing ring is provided between the two walls of the annular groove and the atomizing body 100. In this way, the use of the sealing ring can reduce the leakage of liquid through the gap between the annular groove and the atomizing body 100.

[0028] Further, in order to realize the automatic control of the microporous atomization sheet 3 and the control valve 7, the atomization system also includes a control device (not shown in the figure), and the microporous atomization sheet 3 and the control valve 7 are respectively connected to the control device by signal, and the control device is used to control the atomization work of the microporous atomization sheet 3 and the work of the control valve 7. According to the above technical scheme, the control device can be used to control the microporous atomization sheet 3 and the control valve 7 to work in coordination. For example, the microporous atomization sheet 3 can be controlled to work intermittently, and the control valve 7 can be used to open the infusion channel (22, 41) to provide the liquid to be atomized to the liquid buffer space 21 when the microporous atomization sheet 3 stops working, and the opening time of the control valve 7 is controlled by a timer so that the liquid buffer space 21 stores an appropriate amount of liquid to be atomized, and then the control valve 7 is used to close the infusion channel (22, 41) and start the microporous atomization sheet 3. In this way, it is possible to provide the liquid to be atomized to the liquid buffer space 21, and it is also possible to alleviate the slow penetration phenomenon caused by the infusion channel (22, 41) being always open.
