[0023] To describe in detail the technical content, structural features, and achieved effects of the present invention, the following will be described in detail in conjunction with the embodiments and the accompanying drawings.

[0024] As Figures 1 to 7 shown, the embodiment of the present invention provides an atomization method for an anti-clogging atomization dispenser. The atomization dispenser 100 has an atomization sheet 1 and a switch cover 2 for covering the atomization outlet. An outlet cavity 3 is provided between the atomization sheet 1 and the switch cover 2. The atomization method includes the following steps:

[0025] S1. Determine the working state of the atomization dispenser 100. The atomization dispenser 100 has a first state of normal operation and a second state in the standby mode. The atomization dispenser 100 operates at a first power in the first state.

[0026] S2. Determine that the atomizing dispenser 100 is in the second state, and detect the state of the switch cover 2. The switch cover 2 has an open state for opening the atomizing outlet and a closed state for closing the atomizing outlet. When the switch cover 2 is in the open state, control the atomizing dispenser 100 to operate at the first power so that the atomizing dispenser 100 is in the first state. Specifically, first, when it is determined that the atomizing dispenser 100 is in the second state in the standby mode, that is, when it is determined that the atomizing dispenser 100 is not in the normal working first state, further detect the state of the switch cover 2. When the state of the switch cover 2 is the open state, control the atomizing dispenser 100 to operate at the first power so that the atomizing dispenser 100 is in the first state to maintain normal operation.

[0027] S3. When it is determined that the atomizing dispenser 100 is in the second state and the switch cover 2 is in the closed state, control the atomizing dispenser 100 to operate at the second power and operate for the first preset time t1, and the second power is greater than the first power. Specifically, when the switch cover 2 is in the closed state, control the atomizing dispenser 100 to operate at the higher second power and operate for the first preset time t1, so as to keep the atomizing sheet 1 of the atomizing dispenser 100 moist on the basis of not affecting the normal operation of the atomizing dispenser 100, and avoid the substances remaining on the atomizing sheet 1 from drying and blocking the atomizing sheet 1. The first preset time t1 can specifically be 0.5 seconds. Of course, in some other embodiments, it can also be 1 second or other times, as long as it is a time that can keep the atomizing sheet 1 moist, and it is not limited here.

[0028] S4. After the second preset time t2 or when it is determined that the humidity in the outlet cavity 3 is less than the first preset value, repeatedly execute the foregoing steps to keep the atomizing sheet 1 in a moist state. Specifically, after the atomizing dispenser 100 operates at the second power for the first preset time t1, the atomizing dispenser 100 stops operating. At this time, the atomizing sheet 1 is in a moist state. When the second preset time t2 has elapsed, or when it is determined that the humidity in the outlet cavity 3 is less than the first preset value, at this time, the humidity of the atomizing sheet 1 becomes lower, and it is necessary to execute steps S1 to S4 again to keep the atomizing sheet 1 moist and avoid blockage.

[0029] Specifically, refer to the appendix Figure 6, when the atomizing dispenser 100 in the embodiment of the present invention is not in use, that is, when it enters the second state of the standby mode, it starts to detect whether the switch cover 2 is in the closed state or the open state. If the switch cover 2 is in the open state, it is determined that the atomizing dispenser 100 is in the first state of normal operation, and only the first power is enabled for spraying. If it is detected that the switch cover 2 is in the closed state, a higher second power is started for spraying, and the spraying stops after the first preset time t1 of spraying. When the time for stopping spraying reaches the second preset time t2 or the humidity in the outlet cavity 3 is less than the first preset value, the humidity of the atomizing sheet 1 becomes lower. At this time, steps S1 to S4 are executed again for automatic high-power spraying, and this cycle continues.

[0030] The general reason for the blockage of the atomizing dispenser 100 is that large particle water molecules or thick drugs are in an inactive state when not vibrating. Coupled with being exposed to the air, it is easy for the water to volatilize, and a solid object remains in the micropores of the atomizing sheet 1, resulting in blockage. In the embodiment of the present invention, aiming at the root cause of this problem, by always keeping the atomizing sheet 1 in a wet state, it is ensured that the objects in the micropores will not solidify, and further the smoothness of the micropores is ensured. In addition, the embodiment of the present invention is carried out when the user is on standby and does not affect the normal use of the user. The atomizing dispenser of the present invention does not always operate at the higher second power. Therefore, the performance of the atomizing sheet 1 will not be damaged due to long-term overload operation, the service life of the atomizing dispenser 100 can be extended, and the spraying effect can be ensured.

[0031] In the embodiment of the present invention, a first switch member is further provided on the atomizing dispenser 100. The switch cover 2 slides up and down to open or close the atomizing outlet. The steps for detecting the state of the switch cover 2 include:

[0032] S21, as Figures 1 to 3 shown, when the switch cover 2 is slid and the atomizing outlet is opened, when the switch cover 2 triggers the first switch member to conduct, it is determined that the switch cover 2 is in the open state. Specifically, the first switch member can be a micro switch, a photoelectric switch, etc. For example, when the first switch is a micro switch, when the switch cover 2 slides down to open the atomizing outlet, the bottom of the switch cover 2 presses the elastic piece of the micro switch, triggering the micro switch to conduct.

[0033] S22, when the first switch member is not conducting, it is determined that the switch cover 2 is in the closed state. Specifically, the first switch member is normally in a non-conducting state, and as long as the first switch member is in a non-conducting state, it is determined that the switch cover 2 is in the closed state.

[0034] In an embodiment of the present invention, the second preset time t2 is determined according to the drying time of the atomizing substance on the atomizing sheet 1. If the second preset time t2 is reached, it means that the atomizing sheet 1 will soon be in a dry state. At this time, the first preset time t1 is atomized automatically at the second power, and this cycle is repeated.

[0035] In an embodiment of the present invention, the atomizing method further includes:

[0036] S5. When the atomizing dispenser 100 operates at the second power, when it is determined that the switch cover 2 is in an open state, the atomizing dispenser 100 is controlled to adjust from operating at the second power to operating at the first power. Specifically, if it is detected that the switch cover 2 is in an open state during the automatic high-power atomizing process, it is considered that the atomizing dispenser 100 needs to be used normally, the automatic atomizing process is exited, and it switches to the first state and operates at the first power. In an embodiment of the present invention, when it is determined that the atomizing dispenser 100 is in the first state of normal operation, only the first power is enabled for atomizing, which will not affect the normal use of the atomizing dispenser 100.

[0037] In an embodiment of the present invention, as Figure 7 shown, a position recognition member is provided on the switch cover 2 of the atomizing dispenser 100. The position recognition member is used to recognize whether the switch cover is ready to be opened. The atomizing method further includes:

[0038] S51. When the position recognition member detects that the switch cover 2 is opened to the first position, the atomizing dispenser 100 is controlled to operate at the second power and operate for a third preset time t3. The third preset time t3 is less than the time for sliding the switch cover 2 from the closed state to the open state. Specifically, when the switch cover 2 slides downward, for example, when the first position corresponds to the switch cover sliding downward by 1 mm, it is determined that the switch cover is ready to be opened. At this time, the atomizing dispenser 100 is controlled to operate at the second power and operate for the third preset time t3. The position recognition member can be a position sensor. When the position sensor detects that the switch cover 2 is opened to the first position and the switch cover 2 has not been in an open state yet, the atomizing dispenser 100 is controlled to operate at the second power and operate for the third preset time t3. The third preset time t3 is very short, for example, it can be 0.5 seconds, so that the micropores of the atomizing sheet 1 can be broken through potential blocked holes by high-power atomization, achieving the purpose of smooth atomization, thereby providing guarantee for the normal operation of the atomizing dispenser 100. And the third preset time t3 is very short, and the third preset time t3 is less than the time for sliding the switch cover 2 from the closed state to the open state, so as to ensure that when the switch cover 2 is in an open state, it can operate at the normal first power without affecting the normal use of the user.

[0039] S52. Determine that the switch cover 2 is in the open state, and start the atomizing dispenser 100 to operate at the first power. Specifically, when the switch cover 2 is in the open state, the atomizing dispenser 100 has already ended its operation at the second power and has broken through the potential clogging holes. The atomizing dispenser 100 can work normally. Since the high-power atomizing time is extremely short, it will not damage the electrical performance of the atomizing sheet 1 due to long-term overloaded operation, and the spraying effect can be ensured.

[0040] In some other specific embodiments of the present invention, a second switch member is further provided on the atomizing dispenser 100. During the process of the switch cover 2 sliding from the closed state to the open state, the second switch member is first triggered to conduct, and then the first switch member is triggered to conduct. The atomizing method further includes:

[0041] S511. Determine that the second switch member is conducting, and control the atomizing dispenser 100 to operate at the second power for a fourth preset time t4, and the fourth preset time t4 is less than the time for sliding the switch cover 2 from the closed state to the open state; specifically, the second switch member can be a micro switch, a photoelectric switch, etc. The second switch member is configured to conduct when the switch cover 2 slides downward, for example, when it slides 1 mm. At this time, it is confirmed that the switch cover is ready to be opened, and the atomizing dispenser 100 is controlled to operate at the second power for the fourth preset time t4. The fourth preset time t4 is very short, for example, it can be 0.5 seconds, so that the micropores of the atomizing sheet 1 can be broken through the potential clogging holes by high-power atomization, achieving the purpose of smooth spraying, thereby providing guarantee for the normal operation of the atomizing dispenser 100. And the fourth preset time t4 is very short, and the fourth preset time t4 is less than the time for sliding the switch cover 2 from the closed state to the open state, so as to ensure that when the switch cover 2 is in the open state, it can operate at the normal first power without affecting the normal use of the user.

[0042] S521. Determine that the switch cover 2 is in the open state, and start the atomizing dispenser 100 to operate at the first power. Specifically, when the switch cover 2 is in the open state, the atomizing dispenser 100 has already ended its operation at the second power and has broken through the potential clogging holes. The atomizing dispenser 100 can work normally. Since the high-power atomizing time is extremely short, it will not damage the electrical performance of the atomizing sheet 1 due to long-term overloaded operation, and the spraying effect can be ensured.

[0043] In the embodiments of the present invention, as Figure 5 and Figure 6As shown, the atomizing dispenser 100 has a main control device, and a timing unit is provided on the main control device. A second preset time t2 is preset in the timing unit. Step S3, after the step of determining that the switch cover 2 is in the closed state and controlling the atomizing dispenser 100 to operate at a second power for a first preset time t1, includes:

[0044] S04. Start the timing of the timing unit. When the timing time reaches the second preset time t2, execute step S4.

[0045] In the embodiment of the present invention, a humidity sensor 4 is provided in the outlet cavity 3. The humidity sensor 4 detects the humidity in the outlet cavity 3 to determine that the humidity in the outlet cavity 3 is less than a first preset value. The first preset value can be obtained through multiple experiments. When the humidity in the outlet cavity 3 is less than the first preset value, it means that the atomizing sheet 1 will soon be in a dry state. At this time, steps S1 to S4 are executed again to perform automatic high-power spraying, and this cycle continues.

[0046] As Figures 5 to 7 shown, the hardware structure of the atomizing dispenser 100 in the embodiment of the present invention includes an external switch cover detection circuit, a main control device, a first power control module, a second power control module, an atomizing sheet 1, and a humidity sensor 4. The external switch cover detection circuit includes the first switch member and the second switch member. The first switch member is used to detect the open state and closed state of the switch cover 2, and the second switch member is used to detect whether the switch cover 2 is ready to be opened. The first power control module and the second power control module can be integrated with the main control device or two separate modules separately provided from the main control device. The first power control module, the second power control module, and the humidity sensor are all electrically connected to the main control device, so that the main control device can control the atomizing dispenser 100 to start spraying at the first power for normal use or control the atomizing dispenser 100 to start spraying at the second power for high-power spraying by controlling the first power control module.

[0047] The embodiment of the present invention also provides a medical atomizing dispenser 100, which atomizes by using the atomizing method of the above-mentioned atomizing dispenser 100. The atomizing method in the embodiment of the present invention is used for the case where the atomized substance is a drug, which can ensure that the objects in the micropores of the atomizing sheet 1 will not solidify, ensure the smoothness of the micropores, achieve the purpose of long-term stable operation required in medical treatment, and avoid the blockage of the atomizing dispenser 100 and delay the use by patients.

[0048] The above-disclosed are only the preferred examples of the present invention. Of course, the scope of the rights of the present invention cannot be limited by this. Therefore, the equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
