Description

Technical Field

[0001] The present invention relates to the technical field of medical care equipment, and in particular to an automatic moxibustion smoke purifier. Background Art

[0002] A moxibustion smoke purifier is an air purification device designed to remove the smoke, odor, and harmful substances produced during moxibustion. It collects and processes the smoke released during moxibustion through physical filtration and chemical adsorption, thereby reducing indoor air pollution and improving air quality. Current moxibustion smoke purifiers primarily consist of a smoke hood, an exhaust fan, a smoke duct, and a smoke filter. The exhaust fan, when operating, transports the moxibustion smoke from the smoke hood through the smoke duct to the smoke filter for filtration. When the exhaust fan of this type of moxibustion smoke purifier is operating to remove smoke, its operating power is fixed. This means that even when the amount of moxibustion smoke is low, the exhaust fan still operates at a high power level, resulting in unnecessary energy waste. While the exhaust fan's gear can be adjusted to operate at a low power level when the amount of smoke is low, this requires manual control. Furthermore, if the amount of smoke increases, the exhaust fan's power needs to be increased to improve suction. This type of moxibustion smoke purifier not only requires manual operation, but also requires manual judgment of the size of the smoke and then pressing a button to increase or decrease the exhaust fan power so that the suction force meets the current amount of smoke. Summary of the Invention

[0003] The present invention aims to provide an automatic moxibustion smoke purifier to solve the problem that the current moxibustion smoke purifier needs to manually judge the size of the smoke and then adjust the power of the exhaust fan.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: an automatic moxibustion smoke purifier, comprising a purifier body, the purifier body comprising a smoke collecting hood, a smoke guide pipe, an exhaust fan and a filter device;

[0005] It also includes a controller, which includes a smoke collection module, a data processing module, a PID control module and an execution module;

[0006] The smoke collection module is used to collect the smoke concentration in the smoke collection hood and transmit the collected smoke concentration to the data processing module and the PID control module;

[0007] The data processing module is used to calculate the operating power of the exhaust fan according to the smoke concentration;

[0008] The execution module is used to receive the power of the exhaust fan calculated by the data processing module, and then control the exhaust fan to operate at the calculated power;

[0009] The PID control module is used to perform calculations based on the smoke concentration signal transmitted by the smoke collection module. When the exhaust fan is in operation, if the smoke concentration in the smoke hood increases per unit time, the PID control module increases the operating power of the exhaust fan through calculation to increase the air intake of the exhaust fan; if the smoke concentration in the smoke hood decreases per unit time, the PID control module reduces the operating power of the exhaust fan through calculation to reduce the air intake of the exhaust fan; when the smoke concentration in the smoke hood remains unchanged, the exhaust fan power is kept unchanged.

[0010] Working principle of the present invention:

[0011] During moxibustion, the smoke rises in the air and enters the smoke hood. At this time, the smoke collection module transmits the collected smoke concentration to the data processing module. The data processing module calculates the corresponding power of the air volume when it is extracted from the smoke hood based on the current smoke concentration, and then starts the exhaust fan through the execution module. At this time, the exhaust fan continues to run and draws the smoke in the smoke hood into the filter device through the smoke guide pipe for purification. If the smoke concentration in the smoke hood gradually increases during the extraction process, the smoke collection module transmits the smoke concentration signal to the PID control module. The PID control module increases the operating power of the exhaust fan through calculation and transmits the increased operating power model to the execution module. The execution module then increases the suction volume of the exhaust fan and speeds up the emission of smoke. When the smoke concentration in the smoke hood begins to gradually decrease, the smoke collection module transmits the smoke concentration signal to the PID control module. The PID control module calculates the reduction of the operating power of the exhaust fan and then transmits the reduced operating power signal to the execution module. The execution module controls the exhaust fan to reduce the operating power. Repeat this adjustment until the speed at which the exhaust fan extracts the smoke from the smoke hood is balanced with the speed at which the smoke enters the smoke hood.

[0012] Beneficial effects of the present invention:

[0013] 1. In this solution, the smoke concentration in the smoke hood is monitored by the smoke collection module, and the smoke concentration is calculated in real time by the data processing module and the PID control module. The operating power of the exhaust fan is automatically adjusted according to the calculation results, which solves the problem of manual operation to adjust the exhaust fan power.

[0014] 2. In this solution, the smoke collection module collects the changes in smoke concentration in real time, and the output processing module and PID control module respond quickly to ensure that the exhaust speed and smoke generation are matched. This can effectively avoid energy waste caused by high power and avoid the smoke overflow in the smoke hood due to insufficient exhaust speed of the exhaust fan.

[0015] 3. This solution absorbs and purifies the moxibustion smoke, thus preventing it from affecting other people in the room, reducing indoor air pollution, and improving breathing comfort during the moxibustion process.

[0016] Furthermore, the smoke collection module uses a laser particle counter. The purpose is that the laser particle counter can accurately measure the smoke concentration in the air, and the laser particle counter is miniature and easy to install in the smoke collection hood.

[0017] Furthermore, the filtering device includes a filter bottle with an exhaust hole at the top. The filter bottle contains filtered water, and the exhaust end of the smoke guide pipe extends downward from the top of the filter bottle into the filter bottle and extends to the inner bottom of the filter bottle. The purpose of this arrangement is to allow smoke discharged from the smoke guide pipe to enter the filtered water in the filter bottle, where the filtered water absorbs particulate matter in the smoke and dissolves water-soluble substances, thereby achieving a filtering and purification effect. The purified gas is then discharged from the filter bottle through the exhaust hole.

[0018] Furthermore, a sponge block is fixedly attached to the filter bottle. The size of the sponge block is the same as the cross-section of the filter bottle and is located below the surface of the filtered water. The purpose of this is to slow the rise of smoke in the filtered water by blocking the sponge block, increasing its contact time with the filtered water and improving the purification effect. At the same time, the porous nature of the sponge block further filters the smoke and divides oversized bubbles in the filtered water into smaller bubbles, thereby increasing the contact area with the filtered water.

[0023] The following is further described in detail through specific implementation methods:

[0024] The embodiment is basically as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown:

[0025] An automatic moxibustion smoke purifier, comprising a purifier body and a controller;

[0026] The purifier body includes a smoke collecting hood 7, a smoke guide pipe 4, an exhaust fan and a filter device.

[0027] The filtering device includes a filter bottle 2, the top of which is provided with an exhaust hole 1, and the filter bottle 2 is filled with filtered water. The outlet end of the smoke guide pipe 4 penetrates downward from the top of the filter bottle 2 into the filter bottle 2 and extends to the inner bottom of the filter bottle 2. A sponge block 3 is fixedly connected to the filter bottle 2. The size of the sponge block 3 is the same as the size of the cross section of the filter bottle 2, and the sponge block 3 is located below the liquid surface of the filtered water.

[0028] The controller includes a smoke collection module 6, a data processing module, a PID control module and an execution module; the smoke collection module 6 adopts a laser particle counter.

[0029] The smoke collection module 6 is used to collect the smoke concentration in the smoke collection hood 7 and transmit the collected smoke concentration to the data processing module and the PID control module;

[0030] The data processing module is used to calculate the operating power of the exhaust fan 5 according to the smoke concentration;

[0031] The execution module is used to receive the power of the exhaust fan 5 calculated by the data processing module, and then control the exhaust fan 5 to operate at the calculated power;

[0032] The PID control module is used to perform calculations based on the smoke concentration signal transmitted by the smoke collection module 6. When the exhaust fan 5 is in operation, if the smoke concentration in the smoke hood 7 increases per unit time, the PID control module increases the operating power of the exhaust fan 5 through calculation to increase the air intake of the exhaust fan 5; if the smoke concentration in the smoke hood 7 decreases per unit time, the PID control module reduces the operating power of the exhaust fan 5 through calculation to reduce the air intake of the exhaust fan 5; when the smoke concentration in the smoke hood 7 remains unchanged, the power of the exhaust fan 5 is kept unchanged.

[0033] The specific implementation process is as follows:

[0034] When performing moxibustion, the moxibustion smoke rises in the air and enters the smoke hood 7. At this time, the smoke collection module 6 transmits the collected smoke concentration to the data processing module. The data processing module calculates the corresponding power of the air volume when it is extracted from the smoke hood 7 based on the current smoke concentration, and then starts the exhaust fan through the execution module. At this time, the exhaust fan continues to run and draws the smoke in the smoke hood 7 into the filter device through the smoke guide pipe 4 for purification. If the smoke concentration in the smoke hood 7 gradually increases during the extraction process, the smoke collection module 6 transmits the smoke concentration signal to the PID control module. The PID control module increases the operating power of the exhaust fan 5 through calculation and transmits the increased operating power model to the execution module. The execution module then increases the suction volume of the exhaust fan 5 and speeds up the emission of smoke. When the smoke concentration in the smoke hood 7 begins to gradually decrease, the smoke collection module 6 transmits the smoke concentration signal to the PID control module. The PID control module calculates the reduction of the operating power of the exhaust fan 5 and then transmits the reduced operating power signal to the execution module. The execution module controls the exhaust fan 5 to reduce the operating power. The adjustment is repeated until the speed at which the exhaust fan 5 extracts the smoke from the smoke hood 7 is balanced with the speed at which the smoke enters the smoke hood 7 .

[0035] After the smoke enters the filter bottle 2 through the smoke guide tube 4, the smoke discharged from the smoke guide tube 4 enters the filtered water of the filter bottle 2, and the particulate matter in the smoke is adsorbed by the filtered water, and the substances soluble in water are dissolved, thereby achieving the effect of filtering and purification. The obstruction of the sponge block 3 delays the floating speed of the smoke in the filtered water, increases the contact time with the filtered water, and improves the purification effect. At the same time, the smoke is further filtered through the porous characteristics of the sponge block 3, and the bubbles with too large a volume in the filtered water are divided into smaller bubbles, thereby increasing the contact area with the filtered water. The purified gas is discharged from the filter bottle 2 through the exhaust hole 1.
