Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular is a multifunctional atomizing drug administration, sputum suction and cleaning device. Background Art

[0002] Traditional suction devices are mainly divided into electric multi-function negative pressure suction devices and simple manual suction devices. These devices are widely used in medical work, suitable for timely suctioning of respiratory mucus or vomiting in military combat medical treatment, as well as in hospitals and homes.

[0003] The functions of traditional suction devices are relatively simple, mainly focusing on suction operations, and are unable to provide medication treatment while suctioning. In response to the limitations of traditional suction devices, the medical field has proposed a multifunctional atomization medication suction device that can achieve atomization medication function while suctioning, which can improve the treatment effect and reduce patient pain.

[0004] When using a multifunctional atomized drug administration and sputum suction cleaning device, the suction part needs to be inserted into the patient's throat for negative pressure suction. In order to reduce the patient's discomfort during sputum suction, the radius of the pipe through which the sputum passes should not be set too large. In addition, the viscosity of the patient's respiratory tract varies. When thicker sputum passes through a channel with a smaller radius, the friction with the pipe and the smaller diameter of the pipe will inevitably cause thick sputum to remain in the pipe. When medical staff remove the pipe, the sputum is likely to fall back into the patient's respiratory tract, affecting both the patient's comfort and the efficiency of sputum suction. Therefore, it is necessary to propose a multifunctional atomized drug administration and sputum suction cleaning device that can reduce the consumption of suction driving force and reduce the sputum falling from the suction tube back into the patient's body. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a multifunctional atomization drug administration and sputum suction cleaning device. By setting an inner tube and an outer tube, the separation of atomization drug administration and sputum suction is realized, the gap between the inner tube and the outer tube is used as the absorption and storage space for sputum, and a protrusion is set in the gap to increase the adhesion effect of sputum and thus reduce the probability of sputum falling out.

[0006] To achieve the above-mentioned objectives, the technical solution of the present invention is as follows: a multifunctional aerosolized medication, sputum suction and cleaning device, comprising an insertion tube, one end of the insertion tube being connected to a driving unit for aerosolizing medication and providing a sputum suction driving force, and an end of the insertion tube away from the driving unit being fixedly connected to an operating head for releasing aerosolized liquid and sucking sputum;

[0007] The insertion tube includes an outer tube and an inner tube. The outer tube is sleeved on the outside of the inner tube and a gap is provided between the inner tube for sputum to pass through. The outer tube is provided with a support block with an annular structure near one end of the operating head. The support block is located in the gap between the outer tube and the inner tube. The inner and outer side walls of the support block are fixedly connected to the inner tube and the outer tube respectively. A number of sputum holes for sputum to pass through are opened on the support block. Check valves are fixedly connected to the sputum holes. The inner wall of the outer tube is provided with a protrusion with a threaded structure.

[0008] The principle of the basic solution is: the operating head is brought to the patient's throat through the insertion tube, the driving part is used to atomize the medicine liquid, provide the driving force for the release of the atomized medicine liquid, and provide the effect of suction driving negative pressure, the inner tube is used as the channel for the atomized medicine liquid, the gap between the outer tube and the inner tube is used as the channel for sputum suction, and the sputum hole is used to limit the backflow of sputum.

[0009] The beneficial effects of the basic scheme are: 1. By setting the gap between the inner tube and the outer tube as a channel and storage space for sputum suction, the driving force required to suck the sputum out of the tube is reduced, thereby improving the suction efficiency.

[0010] 2. Due to the different respiratory conditions of different patients, there are sputums with different viscosities. By setting the protrusions of the threaded structure, the friction between the sputum with high viscosity and the inner wall of the outer tube is increased, and the probability of the sputum being thrown out of the gap and falling back into the patient's respiratory tract when the insertion tube is removed due to the small friction is reduced.

[0011] 3. Since the inner tube and the outer tube are in the patient's throat when they work, the patient's swallowing action will exert inward deformation pressure on the outer tube. By setting the support block and the check valve, on the one hand, the probability of sputum being squeezed out of the gap due to the reduction in the volume of the gap between the inner tube and the outer tube can be reduced. On the other hand, the sputum hole for sputum to enter the gap can be kept from being squeezed and deformed, reducing the problem of the operating head losing its suction effect due to the squeezing force of swallowing and reducing the suction efficiency.

[0012] Furthermore, the operating head includes a mist outlet head and a sputum suction head. The sputum suction head is wrapped around the mist outlet head. The mist outlet head is detachably connected to the end of the inner tube, and the sputum suction head is detachably connected to the end of the outer tube. The gap between the sputum suction head and the mist outlet head is connected to the gap between the outer tube and the inner tube. The mist outlet head is provided with a number of mist outlet holes for spraying atomized liquid medicine, and the inner walls of the mist outlet holes are fixedly connected to a first one-way air valve. The sputum suction head is provided with a number of suction holes for sputum to pass through.

[0013] The beneficial effects of the basic scheme are: due to the negative pressure of sputum suction, the sputum will move into the tube, and there is a possibility of entering the inner tube, overflowing through the mist outlet to perform atomized medication to the patient's respiratory system. By setting a first one-way air valve, the probability of sputum entering the inner tube through the mist outlet during the sputum suction stage can be reduced, reducing the secondary contamination of the inner tube by sputum and reducing the need for subsequent cleaning of the inner tube.

[0014] Furthermore, the driving unit includes a driving box and an intelligent system, the intelligent system is connected to the driving box signal, the inner tube and the outer tube have one end away from the mist outlet, extending through the side wall of the driving box and into the driving box, one end of the inner tube located in the driving box passes through the side wall of the outer tube and is connected to an atomizing component for atomizing the liquid medicine, and one end of the outer tube located in the driving box is connected to a sputum suction component for providing negative pressure drive for sputum suction;

[0015] A drug feeding port is provided on the top of the driving box, which is detachably connected to a drug feeding cover. A sealing ring is detachably connected to the connection between the drug feeding cover and the drug feeding port. A drug feeding pipe is fixedly connected to the bottom of the drug feeding port, and one end of the drug feeding pipe away from the drug feeding port is fixedly connected to a drug storage tank.

[0016] The beneficial effects of the basic scheme are: since the atomized liquid is a mist-like liquid, by setting a sealing ring, on the one hand, it can reduce the contamination of the liquid by air during the process, and on the other hand, maintain the airtightness of the drive box, reduce the problem of the atomized liquid overflowing into the drive box, and improve the efficiency of atomized drug delivery.

[0017] Furthermore, a temperature sensor and a heating plate are fixedly connected to the inner wall of the medicine storage tank.

[0018] The beneficial effect of the basic solution is: when the nebulized liquid medicine with a temperature lower than the respiratory tract temperature enters the respiratory system, it will cause the human body to feel uncomfortable and cough. The temperature of the liquid medicine is detected in real time by the temperature sensor, and the heating plate heats the liquid medicine to achieve the temperature control of the nebulized liquid medicine, thereby improving the patient's comfort when taking the medicine and reducing the efficiency of nebulized medicine due to uncomfortable behaviors such as coughing.

[0019] Furthermore, the atomization assembly includes an atomizer fixedly connected to the bottom of the box, the atomizer input port is fixedly connected to a connecting tube for conveying the liquid medicine to be atomized, the atomizer output port is fixedly connected to the inner tube, the connecting tube is connected to a pump at one end away from the atomizer, the output end of the pump is fixedly connected to the connecting tube, the input end of the pump is fixedly connected to a medicine delivery tube, and the other end of the medicine delivery tube is fixedly connected to one side of the medicine storage tank.

[0020] The beneficial effects of the basic solution are: the nebulizer's atomization and the continuous extraction of the pump provide driving force, so that the atomized liquid medicine enters the inner tube for the next step of transportation, and the atomized liquid medicine is pumped into the patient's respiratory system through the nebulizer, reducing the problem of waste caused by overflow of the atomized liquid medicine.

[0021] Furthermore, the medicine storage tank is fixedly connected to an air supply pipe on the side away from the medicine delivery pipe, and the air supply pipe is connected to the sputum suction component at one end away from the medicine delivery pipe. A first electrically controlled air valve is fixedly connected to the air supply pipe, and a second electrically controlled air valve is fixedly connected to the inner wall of the inner tube located in the drive box.

[0022] The beneficial effects of the basic scheme are: by switching the first electrically controlled air valve and the second electrically controlled air valve, the flow direction restriction in the inner tube and the flow direction restriction in the gap between the inner tube and the outer tube are achieved. On the one hand, the backflow phenomenon is reduced, which affects the efficiency of nebulization and suction. On the other hand, the absorption of nebulization driven by the negative pressure driving force of suction is reduced, thereby reducing the probability of the nebulized drug solution being absorbed before it acts on the patient's respiratory system.

[0023] Furthermore, a button for stopping atomization and starting sputum suction is fixedly connected to the outer top wall of the drive box.

[0024] The beneficial effect of the basic solution is: sending a signal to the intelligent system through a button to control the switching of the first and second electronically controlled gas valves, which is convenient for operation and realizes one-button switching operation steps.

[0025] Furthermore, the sputum suction component includes an elastic contraction tube, in which several springs are provided. One end of the spring is fixedly connected to the top wall of the contraction tube, and the other end of the spring is fixedly connected to the bottom wall of the contraction tube. The bottom of one side of the contraction tube is fixedly connected to the air supply pipe, and the top of the same side of the contraction tube close to the air supply pipe is fixedly connected to the outer tube.

[0026] The beneficial effects of the basic scheme are: due to the elasticity of the contraction tube and the storage pressure properties of the spring, energy storage of the pumped atomized liquid medicine is achieved. By restoring the volume of the contraction tube during the suction process, the stored energy is released through the atmospheric pressure recovery of the contraction tube and the deformation recovery of the spring, thereby providing self-driven negative pressure suction and reducing energy waste.

[0027] Furthermore, a connecting rod is fixedly connected to the top wall of the shrinking cylinder, a second one-way air valve is provided in the opening on the top of the shrinking cylinder, and the connecting rod is away from the shrinking cylinder. The end of the connecting rod passes through the top wall of the drive box and is fixedly connected to the pressing plate, and the connecting rod and the drive box are slidably matched.

[0028] The beneficial effect of the basic solution is that when the negative pressure for suction is insufficient by releasing the stored energy, the contraction tube can be repeatedly compressed and restored by pressing the plate, so that the negative pressure for suction can be manually provided, reducing the probability of sputum not being completely cleaned due to insufficient negative pressure, reflecting its versatility.

[0029] Furthermore, the intelligent system includes a temperature acquisition module, a temperature analysis module, a temperature drive module and a control drive module;

[0030] Temperature acquisition module, used to collect the temperature signal of the drug solution and convert it into temperature data;

[0031] The temperature analysis module is used to compare the temperature of the administered liquid with the normal human body temperature, and send a signal when the liquid temperature is lower than the human body temperature;

[0032] The temperature drive module is used to control the activation of the heating plate to heat the liquid medicine;

[0033] The control drive module is used to control the switching of the on / off states of the first electrically controlled gas valve and the second electrically controlled gas valve.

[0034] The beneficial effects of the basic solution are: intelligent control of temperature collection and temperature rise is achieved through the intelligent system, which facilitates temperature detection and heating operations, and the driving of the first and second electronically controlled gas valves through signals enables more convenient and quick operation.

DETAILED DESCRIPTION

[0040] The following is further described in detail through specific implementation methods:

[0041] Example 1:

[0042] Basically as attached Figure 1、 Figure 2 、 Figure 3 and Figure 4 As shown: A multifunctional aerosol drug administration and sputum suction cleaning device includes an insertion tube 1, which is made of an elastic rubber material that is harmless to the human body. One end of the insertion tube 1 is connected to a driving part for aerosolizing drug liquid and providing sputum suction driving force, and the end of the insertion tube 1 away from the driving part is welded and connected to an operating head 2 for releasing aerosol liquid and sucking sputum; when the patient needs to administer drug and clean the respiratory tract, the insertion tube 1 is first inserted into the patient's mouth so that the operating head 2 reaches the patient's throat, and the driving part is started to realize the operation of aerosolizing drug administration and sputum suction cleaning by the operating head 2 in the patient's throat, thereby aerosolizing drug administration and sucking sputum for the patient in the throat.

[0043] The insertion tube 1 includes an outer tube 101 and an inner tube 102. The outer tube 101 is sleeved on the outside of the inner tube 102 and a gap for sputum to pass through is provided between the outer tube 101 and the inner tube 102. A support block 103 with an annular structure is provided at one end of the outer tube 101 near the operating head 2. The support block 103 is located in the gap between the outer tube 101 and the inner tube 102. The inner and outer side walls of the support block 103 are respectively welded to the inner tube 102 and the outer tube 101. A number of sputum holes for sputum to pass through are opened on the support block 103, and check valves 104 are welded in the sputum holes. A protrusion 105 with a threaded structure is provided on the inner wall of the outer tube 101. When the insertion tube 1 is inserted into the throat, the drive unit is started to realize the atomization of the medicine liquid. The atomized medicine liquid overflows from the operating head 2 through the inner tube 102 and directly acts on the patient's respiratory system. On the one hand, it is beneficial to the drug administration efficiency of the patient's respiratory system. On the other hand, it is beneficial to moisten the dry sputum and facilitate the subsequent absorption of sputum.

[0044] After the nebulization medication is finished, when the patient performs the sputum suction operation, the negative pressure generated by the driving part acts on the gap between the outer tube 101 and the inner tube 102, and the sputum will be sucked into the gap through the operating head 2. The support block 103 is provided to support the gap between the inner tube 102 and the outer tube 101, reducing the probability that the outer tube 101 and the inner tube 102 are closed and the sputum suction operation cannot be performed due to the pressure exerted by the patient's throat on the outer tube 101. In addition, since the outer tube 101 is provided with a threaded protrusion 105, the friction between the sputum and the wall of the outer tube 101 is increased, and the check valve 104 is used to ensure that the path of the sputum is from the operating head 2 to the gap between the outer tube 101 and the inner tube 102. On the one hand, the sputum can be absorbed and stored in the gap between the outer tube 101 and the inner tube 102. On the other hand, it reduces the probability that the sputum will fall back into the patient's respiratory system due to the centrifugal force caused by inertia when the inner tube 102 and the outer tube 101 are subsequently removed.

[0045] In addition, due to the different viscosities of sputum or the differences in the effects of atomized administration, using the gap between the outer tube 101 and the inner tube 102 as a space for storing sputum can reduce the probability that some sputum cannot be absorbed and improve the efficiency of the operating head 2 in absorbing sputum.

[0046] Example 2:

[0047] As attached Figure 2 and Figure 4 As shown, the difference from the above embodiment is that the operating head 2 includes a mist outlet head 201 and a sputum suction head 202, the sputum suction head 202 is wrapped outside the mist outlet head 201, the mist outlet head 201 and the end of the inner tube 102 are detachably connected by a snap structure, the sputum suction head 202 and the end of the outer tube 101 are detachably connected by a snap structure, the gap between the sputum suction head 202 and the mist outlet head 201 is connected to the gap between the outer tube 101 and the inner tube 102, and the mist outlet head 201 is provided with a plurality of The mist outlet hole from which the medicine liquid is sprayed has a first one-way air valve 203 welded to its inner wall; in the process of atomizing the medicine, the atomized medicine liquid reaches the mist outlet head 201 through the inner tube 102, and overflows through the mist outlet hole to perform atomization medicine on the patient's respiratory system. By setting the first one-way air valve 203, the probability of sputum entering the inner tube 102 through the mist outlet hole during the sputum absorption stage can be reduced, the secondary contamination of the inner tube 102 by the sputum can be reduced, the steps for cleaning the inner tube 102 can be reduced, and the operation is facilitated.

[0048] The suction head 202 is provided with a number of suction holes for sputum to pass through; during the suction operation, the sputum will enter the gap between the suction head 202 and the mist outlet head 201 through the suction holes, and then enter the gap between the outer tube 101 and the inner tube 102 under the action of the negative pressure of the driving part, thereby achieving the effect of sputum suction and collection. In addition, the suction holes also serve as channels for the atomized liquid to overflow the suction head 202, without affecting the overflow of the atomized liquid.

[0049] Example 3:

[0050] As attached Figure 1 and Figure 3As shown, the difference from the above embodiment is that the driving part includes a driving box 3 and an intelligent system, the intelligent system is connected to the driving box 3 signal, the inner tube 102 and the outer tube 101 are away from the mist outlet 201, one end passes through the side wall of the driving box 3 and extends into the driving box 3, one end of the inner tube 102 located in the driving box 3 passes through the side wall of the outer tube 101 and is connected to an atomizing component for atomizing the medicine liquid, and one end of the outer tube 101 located in the driving box 3 is connected to a sputum suction component for providing sputum suction negative pressure drive; the driving part realizes the atomization operation and transportation operation of the medicine liquid through the atomizing component, the atomized medicine liquid enters the inner tube 102 and is transported to the other end of the inner tube 102 for drug administration operation, and is connected to the outer tube 101 through the sputum suction component, so that the negative pressure generated by the sputum suction component can be transmitted to the gap between the outer tube 101 and the inner tube 102, thereby achieving the sputum suction effect.

[0051] A medication port is provided on the top of the driving box 3, and the medication port is detachably connected to a medication cover 302 through a snap-fit ​​structure. A sealing ring 303 is provided at the connection between the medication cover 302 and the medication port. A medication tube 401 is welded to the bottom of the medication port, and the end of the medication tube 401 away from the medication port is welded and fixedly connected to the medication storage tank 4; medical staff put the liquid medicine to be atomized into the driving box 3 through the medication port, and then close the medication cover 302 to achieve an airtight and leak-proof effect between the medication tube 401 and the medication storage tank 4.

[0052] Example 4:

[0053] As attached Figure 3 As shown, the difference from the above embodiment is that a temperature sensor 402 and a heating plate 403 are welded to the inner wall of the medicine storage tank 4; in the atomization drug administration stage, since the temperature of the human respiratory system is close to body temperature, the supercooled drug liquid is directly atomized and administered to the patient's respiratory system, which is likely to cause discomfort to the patient during the drug administration process. The temperature of the drug liquid in the medicine storage tank 4 is detected in real time by the temperature sensor 402, and then the heating plate 403 is controlled by the intelligent system to heat the drug liquid in the medicine storage tank 4, so that the temperature of the drug liquid reaches a temperature that allows the patient to take the drug comfortably, thereby achieving a multi-functional atomization drug administration effect.

[0054] Example 5:

[0055] As attached Figure 3As shown, the difference from the above embodiment is that the atomization assembly includes an atomizer 5 welded to the bottom of the box body, the inlet of the atomizer 5 is melted and connected to a connecting pipe 501 for conveying the liquid medicine to be atomized, the outlet of the atomizer 5 is melted and connected to the inner tube 102, the connecting pipe 501 is connected to the end away from the atomizer 5 with a pump 502, the output end of the pump 502 is melted and connected to the connecting pipe 501, the input end of the pump 502 is connected to a drug delivery pipe 503, and the other end of the drug delivery pipe 503 is melted and connected to one side of the medicine storage tank 4; the process of atomizing the liquid medicine is to use the pump 502 to pump the liquid medicine in the medicine storage tank 4 through the drug delivery pipe, the pump 502 and the connecting pipe 501 in sequence into the atomizer 5, the atomization of the atomizer 5 and the continuous extraction of the pump 502 provide a driving force, so that the atomized liquid medicine enters the inner tube 102 for the next step of transportation, thereby achieving the effect of the atomized liquid medicine being pumped to the patient's respiratory system by the atomizer 5.

[0056] Example 6:

[0057] As attached Figure 3 As shown, the difference from the above embodiment is that the medicine storage tank 4 is melted and connected to the air delivery pipe 602 on the side away from the medicine delivery pipe 503, and the other end of the air delivery pipe 602 is connected to the sputum suction component. A first electrically controlled air valve 603 is welded in the air delivery pipe 602, and a second electrically controlled air valve 106 is welded to the inner wall of the inner tube 102 located in the driving box 3. A button 301 for stopping atomization and starting sputum suction is welded on the outer top wall of the driving box 3; during the process of atomizing the drug for the patient, the first electrically controlled air valve 603 is in the open state and the second electrically controlled air valve 106 is in the closed state, so that the flow direction of several tubes in the driving box 3 is from the sputum suction component to the sputum suction component. The liquid flows to the air supply pipe 602, and then from the air supply pipe 602 to the medicine storage tank 4, and then from the medicine storage tank 4 to the medicine delivery pipe 503, and from the medicine delivery pipe 503 to the nebulizer 5, and finally from the nebulizer 5 to the inner tube 102; at this time, the connection between the outer tube 101 and the sputum suction component is cut off, that is, there is no negative pressure to generate suction force; when the atomization drug administration is ended, the intelligent system can control the first electrically controlled air valve 603 to be converted into a closed state, and the second electrically controlled air valve 106 to be converted into an open state, so that the connection between the outer tube 101 and the sputum suction component is restored, and the connection between the air supply pipe 602 and the sputum suction component is cut off, thereby achieving the effect of sputum suction.

[0058] Example 7:

[0059] As attached Figure 3As shown, the difference from the above embodiment is that the sputum suction component includes an elastic shrinking tube 6, and a plurality of springs 601 are provided in the shrinking tube 6. One end of the spring 601 is welded to the inner top wall of the shrinking tube 6, and the other end of the spring 601 is welded to the inner bottom wall of the shrinking tube 6. The bottom of one side of the shrinking tube 6 is melted and connected to the air supply pipe 602, and the top of the same side of the shrinking tube 6 close to the air supply pipe 602 is melted and connected to the outer tube 101; in the process of realizing aerosol drug administration, since the sealing ring 303 forms a sealed space with the medicine storage tank 4, the volume in the medicine storage tank 4 remains unchanged during the process, and the extraction of the liquid medicine reduces the volume. A difference in atmospheric pressure between the medicine storage tank 4 and the shrink tube 6 will occur, causing the gas in the shrink tube 6 to be pumped into the medicine storage tank 4. Since the shrink tube 6 is also in a sealed state, the volume of the shrink tube 6 is reduced. At this time, the closed state of the second electrically controlled air valve 106 makes it impossible for the shrink tube 6 to replenish the gas balance pressure difference. The atmospheric pressure inside and outside the shrink tube 6 will exert pressure on the side wall of the shrink tube 6, causing the shrink tube 6 to be continuously compressed, thereby reducing the volume of the shrink tube 6. At this time, the spring 601 will be deformed under pressure to continuously store the downward pressure until the atomization drug delivery process is completed.

[0060] When the atomization drug administration process is completed and the suction operation begins, the second electrically controlled air valve 106 is opened and the first electrically controlled air valve 603 is closed. At this time, the connection between the outer tube 101 and the contraction tube 6 is restored. At the same time, the spring 601 releases the stored pressure to restore the volume of the contraction tube 6, so that the gas in the gap between the outer tube 101 and the inner tube 102 and the gap between the suction head 202 and the mist outlet head 201 will escape into the contraction tube 6. At this time, the negative pressure generated by the contraction tube 6 will produce a suction effect, acting on the suction head 202 to produce a suction effect; the effect of self-driven suction negative pressure is achieved, which saves resources and facilitates operation.

[0061] A connecting rod 604 is welded to the top wall of the contraction tube 6, and a second one-way air valve 606 is provided at the top opening of the contraction tube 6. A pressing plate 605 is welded to the top wall of the drive box 3 at one end of the connecting rod 604 away from the contraction tube 6, and the connecting rod 604 slides with the drive box 3; considering that some patients have different sputum consistencies and accumulation conditions, when the negative pressure generated by the deformation stored in the contraction tube 6 cannot completely absorb the sputum, since the gas flow direction of the second one-way air valve 6 is from the inside of the contraction tube 6 to the outside of the contraction tube 6, at this time, the medical staff compresses the contraction tube 6 by pressing the pressing plate 605 to reduce the volume of the contraction tube 6, and pulls up the pressing plate 605 to restore the volume of the contraction tube 6. Repeated operations continuously generate negative pressure for suctioning sputum to absorb the sputum, which can reduce the probability of incomplete absorption of sputum.

[0062] Example 8:

[0063] The difference from the above embodiment is that the intelligent system includes a temperature acquisition module, a temperature analysis module, a temperature drive module and a control drive module.

[0064] The temperature acquisition module collects the temperature signal of the liquid in the liquid storage tank through the temperature sensor 402, and converts the temperature signal into temperature data and transmits it to the temperature analysis module.

[0065] The temperature analysis module is used to receive temperature data and compare the temperature data with the human body temperature of 37°C. When the temperature data of the medicine liquid is greater than 37°C, a signal to stop heating is sent to the temperature driving module. When the temperature data is less than 37°C, a signal to increase the temperature is sent to the temperature driving module.

[0066] The temperature driving module is used to receive the signal of needing to increase the temperature and stopping the temperature increase, and drive and control the heating plate 403 to start and stop after receiving the signal.
