Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen-rich water preparation, specifically to an optimization technology for a pressure cutting link in a hydrogen-rich water production process, and especially to a hydrogen-rich water preparation device with an anti-escape mechanism. Background Art

[0002] Hydrogen-Rich Water (HRW), which is "water rich in dissolved hydrogen molecules", is commonly called "hydrogen molecule bubble water" or "hydrogen water". Hydrogen-rich water not only plays an important role in the biomedical field in reducing tissue oxidative damage after ischemia-reperfusion, inhibiting inflammatory response, preventing and treating metabolic diseases, preventing and treating arteriosclerosis and treating ophthalmic diseases, but also plays an important role in the field of crops in promoting biosynthesis, preventing and treating oxidative damage and increasing growth hormone levels.

[0003] The preparation of hydrogen-rich water is relatively simple, that is, hydrogen and raw water are mixed in a certain proportion to form a hydrogen-water mixture. This mixing process generally adopts pressure cutting technology, such as the bubble cutter technology disclosed by the applicant on December 19, 2023 (authorization number: CN220194673U): that is, part of the hydrogen-water mixture is pressurized to no more than 20MPa by a high-pressure pump, and then a bubble cutting head is used to form a hedge in the atmospheric pressure chamber to cut the hydrogen bubbles in the atmospheric pressure chamber to reduce the bubble diameter and achieve mixing of hydrogen and raw water.

[0004] However, after long-term application, the applicant found that because the solubility of hydrogen in water is low, and the surface area of ​​hydrogen bubbles is small when they are large, the contact area with water is limited. Therefore, although one cutting can reduce the bubble diameter, the bubbles directly enter the normal pressure environment after cutting. Because the hydrogen molecules inside the large bubbles are subjected to relatively small external pressure, the large pressure difference and small bubble diameter may cause the bubbles to rise rapidly and escape, which in turn leads to unsatisfactory effect of the equipment in preparing hydrogen-rich water.

[0005] At the same time, the applicant also found that during the above-mentioned hydrogen escape process, when the hydrogen-water mixture enters the low-pressure environment from the high-pressure environment of the cutter, part of the liquid that escapes the hydrogen will be retained in the pipeline due to the pressure drop and form residual water. This residual water does not fully participate in the cutting process, but accumulates inside the pipeline or equipment, resulting in waste of resources and impact on the equipment.

[0006] To this end, a hydrogen-rich water preparation device with an anti-escape mechanism is proposed. Utility Model Content

[0007] In view of this, the present invention aims to provide a hydrogen-rich water preparation device with an anti-escape mechanism to solve or alleviate the technical problems existing in the prior art, namely:

[0008] (1) How to solve the problem of hydrogen escape;

[0009] (2) How to further solve the problem of resource waste caused by residual water on the basis of solving the problem of hydrogen escape;

[0010] The technical solution of the present utility model is achieved as follows:

[0011] A hydrogen-rich water preparation device with an anti-escape mechanism includes a hydrogen generator 8 for preparing hydrogen installed in a housing 1. The improvement of this solution is that it includes the following components installed in the housing 1:

[0012] A gas-liquid mixing pump 7 for mixing the raw water and the hydrogen to form a hydrogen-water mixture;

[0013] A pressure cutting component is connected to the gas-liquid mixing pump 7 and is used to cut bubbles from the hydrogen-water mixture and to subject the mixture to multiple pressure differences, especially the alternating effects of high-pressure and low-pressure environments, so that the hydrogen in the hydrogen-water mixture no longer escapes.

[0014] In one embodiment, the pressure cutting assembly includes a first pressure cutter 4 and a second pressure cutter 5. The gas-liquid mixing pump 7 is connected to the first pressure cutter 4, and the first pressure cutter 4 is connected to the second pressure cutter 5 via a booster pump 10. The first pressure cutter 4 pressurizes the hydrogen-water mixture to no more than 10 MPa, and the second pressure cutter 5 pressurizes the hydrogen-water mixture to no more than 20 MPa.

[0015] After initial cutting by the first pressure cutter 4, the bubbles in the hydrogen-water mixture have been refined to a certain extent. In the second pressure cutter 5, the higher pressure causes the bubbles to be further cut into smaller nanoscale bubbles. This continuous refinement process greatly increases the surface area of ​​the bubbles, significantly improving the contact efficiency between hydrogen and water. Simultaneously, the hydrogen-water mixture in the second pressure cutter 5 can be further returned to the first pressure cutter 4, forming an alternating effect.

[0016] In one embodiment, the system further includes a storage tank 2 mounted within the housing 1 for storing the raw water, and a water purifier 3 connected to the storage tank 2 for purifying the raw water. The storage tank 2 receives the raw water (purified water, tap water, mineral water, etc.), while the water purifier 3 is responsible for purifying the raw water. The water purifier 3 is connected to a three-way valve. One path of the three-way valve is connected to the hydrogen generator 8, for transferring a portion of the purified raw water to the hydrogen generator 8; the other path of the three-way valve is connected to the gas-liquid mixing pump 7, for transferring another portion of the purified raw water to the gas-liquid mixing pump 7.

[0017] In one embodiment, the housing 1 further includes a gas-water storage barrel 9 for storing the hydrogen-water mixture generated by the initial cutting by the first pressure cutter 4 and for storing the hydrogen-water mixture generated by the alternating cutting by the second pressure cutter 5.

[0018] The first pressure cutter 4 first stores the generated hydrogen-water mixture in the gas-water storage barrel 9. Based on the product's production quota, it can determine whether to directly discharge the hydrogen-water mixture from the gas-water storage barrel 9 or return it to the second pressure cutter 5 for further cutting. Furthermore, after the second pressure cutter 5 completes cutting, it also first stores the generated hydrogen-water mixture in the gas-water storage barrel 9 and, based on the aforementioned logic, determines whether to return to the first pressure cutter 4 for another alternate cutting session.

[0019] In one embodiment, the gas-water storage tank 9 is further connected to a return water control valve 6, which is connected to the storage tank 2 via a pressure pump. Specifically, when the gas-liquid mixing pump 7 mixes the raw water and hydrogen to form a hydrogen-water mixture, which is then passed to the first pressure cutter 4 for a first pressure cut and introduced into the gas-water storage tank 9, residual water will inevitably be generated if the hydrogen-water mixture returns to the second pressure cutter 5. This residual water can then be returned to the storage tank 2 via the pressure pump. Even if it is contaminated during this process, it can be purified by the water purifier 3 during the next preparation process, thus minimizing water waste.

[0020] In one embodiment, the gas-water storage tank 9 is connected to a storage tank 11 for storing finished hydrogen-rich water. That is, after multiple rounds of alternating cutting by the first pressure cutter 4 and the second pressure cutter 5, when the hydrogen-water mixture is deemed by the staff to meet the relevant production tasks or process indicators, the hydrogen-water mixture in the storage tank 9 is transferred to the storage tank 11 via another pressure pump to form the desired hydrogen-rich water.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) Improve the quality of hydrogen-rich water: The utility model significantly refines the diameter of bubbles in the hydrogen-water mixture through multiple rounds of alternating cutting by the first and second pressure cutters, making the hydrogen more evenly distributed in the water and having higher solubility. This helps to improve the antioxidant capacity and bioavailability of hydrogen-rich water, thereby enhancing its benefits to human health.

[0023] (2) Efficient use of water resources: This utility model introduces an air-water mixing storage tank as an intermediate buffer and regulation link, which not only achieves flexible control of the cutting process, but also realizes the effective recovery and reuse of excess water through the design of the return water control valve and pressure pump. This not only reduces the waste of water resources, but also reduces production costs, which is in line with the concept of sustainable development.

[0024] (3) Enhanced process flexibility: The basic structural form of the utility model objectively allows operators to flexibly adjust the number of cuts and cycle flow according to production task indicators and process requirements. This high degree of process flexibility ensures that the hydrogen-rich water preparation process can adapt to different production scenarios and needs, improving the versatility and applicability of the equipment.

[0025] (4) Reduced production costs: This solution excels in reducing production costs by optimizing the cutting process and improving water resource utilization. On the one hand, by reducing water waste and recycling water resources, water bills are reduced; on the other hand, by improving the quality and output of hydrogen-rich water, the added value and market competitiveness of the product are increased.

[0026] (5) Significant environmental benefits: The technical solution of this utility model focuses on environmental benefits during the production process. By reducing wastewater discharge and recycling surplus water, it reduces the impact on the environment. This not only meets the requirements of environmental protection, but also lays a good foundation for sustainable development. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Explanation of terms in this specific implementation method:

[0033] (1) Hydrogen-water mixture: refers to the mixture obtained by mixing hydrogen and raw water by the gas-liquid mixing pump 7 and cutting it by the first pressure cutter 4 and / or the second pressure cutter 5. When the mixture does not reach the storage tank 11, it is collectively referred to as hydrogen-water mixture and is regarded as a semi-finished product that has not yet reached the predetermined preparation process or production indicators;

[0034] (2) Hydrogen-rich water: The hydrogen-water mixture stored in the storage tank 11 is considered to be a product that meets the predetermined preparation process or production indicators.

[0035] (3) The first pressure cutter 4 and the second pressure cutter 5: both are the components of the “nano-cutting device 6” in the utility model patent authorization number: CN220194673U of “A nano-bubble cutter” disclosed by the applicant on December 19, 2023.

[0036] Example: The preparation of hydrogen-rich water is relatively simple, that is, hydrogen and raw water are mixed in a certain proportion to form a hydrogen-water mixture. This mixing process is generally bubble cutter technology. However, because the solubility of hydrogen in water is low, and because the surface area of ​​hydrogen bubbles is small when they are large, the contact area with water is limited. Therefore, although one cutting can reduce the bubble diameter, the bubbles enter the normal pressure environment directly after cutting, and the hydrogen molecules inside the large bubbles are subjected to relatively small external pressure. The large pressure difference and small bubble diameter may cause the bubbles to rise rapidly and escape, which in turn leads to unsatisfactory results in the preparation of hydrogen-rich water by the equipment. In order to solve this technical problem, please refer to the following. Figures 1-2 The device for producing hydrogen-rich water with an anti-escape mechanism shown in FIG. includes a hydrogen generator 8 for producing hydrogen, mounted within a housing 1. A storage tank 2 is installed within the housing 1 and stores various raw waters, such as purified water, tap water, or mineral water. These raw waters are fed into the storage tank 2 via external pipes. A water purifier 3 is then connected to the storage tank 2 to purify the raw water, removing impurities, suspended matter, and other components that could affect the quality of the hydrogen-rich water.

[0037] Specifically, the raw water purified by the water purifier 3 is then diverted through a three-way valve. One path of the three-way valve is connected to the hydrogen generator 8, supplying a portion of the purified raw water to the hydrogen generator 8 for electrolysis or chemical reaction to generate hydrogen. The other path is directly connected to the gas-liquid mixing pump 7, which provides the other portion of purified raw water required for the hydrogen-water mixing process. The hydrogen generated by the hydrogen generator 8 is transported to the gas-liquid mixing pump 7 through a pipeline and mixed with the raw water from the water purifier 3 to form an initial hydrogen-water mixture.

[0038] It is understandable that purifying the raw water by the water purifier 3 can ensure the purity of the water quality in the subsequent hydrogen dissolution process and reduce the possibility of bubble escape. Secondly, the design of the three-way valve enables the purified raw water to be flexibly distributed to the hydrogen generator 8 and the gas-liquid mixing pump 7, which not only meets the needs of hydrogen generation, but also provides a stable water source for hydrogen-water mixing. In addition, by precisely controlling the diversion ratio of the raw water, the dissolution efficiency of hydrogen and the quality of hydrogen-rich water can be further optimized.

[0039] It should be noted that the hydrogen generator 8 can be either a traditional electrolysis type or a traditional hydrogen rod type.

[0040] In this embodiment, the purified raw water and the generated hydrogen need to be mixed into a hydrogen-water mixture. To achieve this goal, a gas-liquid mixing pump 7 is installed at an appropriate position in the housing 1. Its function is to mix the raw water (water that has been properly pretreated) with the hydrogen generated by the hydrogen generator 8 to form a preliminary hydrogen-water mixture. Subsequently, the hydrogen-water mixture is directed to a pressure cutting assembly. The pressure cutting assembly is composed of multiple pressure chambers in series, and each chamber is provided with a bubble cutting structure, such as a nano-cutting head. The hydrogen-water mixture first enters the first high-pressure chamber. In this chamber, the hydrogen-water mixture is pressurized to a preset high-pressure range (such as 13 to 20 MPa) by a specific pressurizing device (such as a high-pressure pump), and then enters the cutting area for initial bubble cutting. The cut hydrogen-water mixture is then released into a low-pressure environment (i.e., a normal pressure chamber or a slightly lower pressure chamber), so that the bubbles are further refined and their escape is reduced during the pressure drop. After the initial cutting, the hydrogen-water mixture continues to flow to the next high-pressure chamber for secondary pressurization and cutting. This process is repeated many times. Through the alternating action of high-pressure and low-pressure environments, the bubbles in the hydrogen-water mixture are continuously refined, while minimizing the escape of hydrogen.

[0041] Specifically, the pressure cutting component uses the principle of alternating high-pressure and low-pressure environments to efficiently cut bubbles in the hydrogen-water mixture and reduce hydrogen escape. In a high-pressure environment, the hydrogen-water mixture is pressurized to a certain value, which significantly increases the fluid velocity and kinetic energy, contributing to the rupture and refinement of the bubbles. Subsequently, when the high-pressure hydrogen-water mixture enters a low-pressure environment, the pressure drop causes the pressure difference inside and outside the bubbles to rapidly expand and rupture into smaller bubbles. This alternating action of high and low pressure not only promotes the continuous refinement of the bubbles, but also reduces the possibility of hydrogen escaping from the bubbles by shortening the residence time of the bubbles in the low-pressure environment. In addition, multiple pressure differential effects further enhance the refinement effect of the bubbles, ensuring the stability and high density of hydrogen in the final product.

[0042] It is understandable that by introducing the pressure cutting component, efficient nano-scale cutting of bubbles in the hydrogen-water mixture is achieved, making the distribution of hydrogen in the final product more uniform and the bubble diameter smaller (reaching the nanoscale), thereby improving the solubility and stability of hydrogen. At the same time, through the alternating effect of high-pressure and low-pressure environments, the escape of hydrogen during the preparation process is effectively reduced, ensuring the high-quality output of hydrogen-rich water. In addition, the device also has good flexibility and controllability. Parameters such as the number of pressure cuttings, pressure range, and configuration of the cutting head can be adjusted according to actual needs to meet the requirements of hydrogen-rich water quality in different application scenarios.

[0043] Furthermore, to achieve the function of the pressure cutting assembly described above, the pressure cutting assembly includes a first pressure cutter 4 and a second pressure cutter 5. A gas-liquid mixing pump 7 is connected to the first pressure cutter 4, and the first pressure cutter 4 is connected to the second pressure cutter 5 via a booster pump 10. The first pressure cutter 4 pressurizes the hydrogen-water mixture to no more than 10 MPa, and the second pressure cutter 5 pressurizes the hydrogen-water mixture to no more than 20 MPa.

[0044] The gas-liquid mixing pump 7 first mixes the raw water with the hydrogen produced by the hydrogen generator 8 to form an initial hydrogen-water mixture. This mixture is then introduced into the first pressure cutter 4. Inside the first pressure cutter 4, the hydrogen-water mixture is pressurized to a pressure of no more than 10MPa by the action of the booster pump 10. Under this pressure, the bubbles in the hydrogen-water mixture begin to be initially refined, and some large bubbles are cut into smaller bubbles. After completing the initial cutting, the hydrogen-water mixture is transported to the second pressure cutter 5 via a pipeline. In the second pressure cutter 5, the hydrogen-water mixture is pressurized again, but this time the pressure is increased to no more than 20MPa. The higher pressure environment prompts the bubbles to be further cut into nanoscale bubbles, thereby achieving more refined bubble refinement. In addition, according to the process requirements, the hydrogen-water mixture processed by the second pressure cutter 5 can be selectively returned to the first pressure cutter 4 for multiple cycle cutting to further optimize the nanoscale refinement effect of the bubbles.

[0045] Specifically, the hydrogen-water mixture processed by the second pressure cutter 5 is selectively returned to the first pressure cutter 4 for further cutting. This is essentially equivalent to multiple cycles of cutting, and the bubbles in the hydrogen-water mixture undergo a further refinement process, allowing the bubble diameter to be further reduced to the nanometer level. This more refined bubble refinement helps increase the solubility of hydrogen in the hydrogen water, thereby improving the quality and efficacy of hydrogen-rich water. This can make the bubble distribution in each batch of hydrogen-rich water more uniform and the bubble diameter more consistent. This helps to improve the stability and consistency of the product.

[0046] Specifically, on the flow path of the hydrogen-water mixture, pressure pumps of different specifications and performances are configured for the first pressure cutter 4 and the second pressure cutter 5, respectively.

[0047] (1) The first pressure cutter 4 is equipped with a pressure pump capable of pressurizing the hydrogen-water mixture to no more than 10 MPa. Alternatively, the through-groove aperture and micropores are designed with targeted dimensions and quantity.

[0048] (2) The second pressure cutter 5 is equipped with a pressure pump capable of pressurizing the hydrogen-water mixture to no more than 20 MPa. The pump should have a high outlet pressure capability. Alternatively, the through-groove aperture and micropores are designed with targeted dimensions and quantity.

[0049] (3) Install a pressure sensor at the outlet of each pressure pump to monitor the output pressure in real time. Based on the feedback from the pressure sensor, the operating state of the pressure pump is automatically adjusted through a PLC (programmable logic controller) or other control system to ensure that the output pressure is stable within the set range. PLC can also be omitted, but corresponding control elements, such as a pressure regulating valve, need to be added to achieve precise control of the output pressure.

[0050] It should be pointed out that the above-mentioned principle of preventing hydrogen from escaping is to utilize the fluid dynamic characteristics under different pressure environments to achieve efficient cutting and thinning of bubbles. In the first pressure cutter 4, the moderate pressure environment causes the bubbles in the hydrogen-water mixture to begin to be subjected to the effect of shear force and thinning. Subsequently, in the second pressure cutter 5, the higher pressure not only enhances the kinetic energy of the fluid, but also aggravates the interaction and collision between the bubbles, further promoting the thinning of the bubbles. In addition, through the alternating circulation of the hydrogen-water mixture between the high and low pressure environments, the bubbles have undergone multiple thinning processes, thereby achieving a significant reduction in bubble diameter. This pressure alternation mechanism ensures the efficiency and consistency of the bubble cutting effect.

[0051] It should also be pointed out that this solution achieves multi-level refinement and efficient cutting of bubbles in the hydrogen-water mixture through the series use of two-stage pressure cutters, so that the bubble diameter in the final product can reach the nanoscale level, thereby significantly improving the solubility and stability of hydrogen. Secondly, the pressure alternating action mechanism makes the bubble cutting process more continuous and efficient, reduces the escape of hydrogen during the preparation process, and ensures the high-quality output of hydrogen-rich water. In addition, this implementation method also has good process adaptability and flexibility, and the pressure parameters and number of cycles can be adjusted according to actual needs to meet the quality requirements of hydrogen-rich water in different application scenarios.

[0052] In this embodiment, the hydrogen-water mixture generated by the initial cutting by the first pressure cutter 4 or the hydrogen-water mixture generated by the alternating cutting by the second pressure cutter 5 needs to be stored in a gas-water storage tank 9 .

[0053] Specifically: The gas-water mixture storage barrel 9 is installed inside the casing 1. It is designed to store the hydrogen-water mixture after the initial cutting by the first pressure cutter 4. It also serves as a temporary storage container for the hydrogen-water mixture after the alternating cutting by the second pressure cutter 5. During the production process, the first pressure cutter 4 first performs initial cutting on the hydrogen-water mixture, and then introduces the cut hydrogen-water mixture into the gas-water mixture storage barrel 9 for temporary storage. According to the specific requirements of the production task, the operator can decide whether to directly guide the hydrogen-water mixture from the gas-water mixture storage barrel 9 for subsequent processing, or return it to the second pressure cutter 5 for more refined cutting. Similarly, when the second pressure cutter 5 completes the cutting, the processed hydrogen-water mixture will also be introduced into the gas-water mixture storage barrel 9, and then the same logic will be used to decide whether it needs to be returned to the first pressure cutter 4 for alternating cutting again to achieve the desired bubble refinement effect.

[0054] It should be noted that the use of the gas-water storage tank 9 as an intermediate buffer and regulation link enables flexible control of the hydrogen-water mixture cutting process. Through the temporary storage and recirculation mechanism, the system can adjust the number and degree of cutting according to actual needs to ensure that the bubble diameter and hydrogen solubility of the final product are optimized. The introduction of the gas-water storage tank 9 makes the cutting process no longer a linear single operation. Instead, it can be repeated and alternately cut according to product requirements and production conditions, thereby improving the bubble refinement effect and the quality of hydrogen-rich water.

[0055] It's understandable that the addition of the gas-water storage tank 9 significantly enhances the functionality and flexibility of the hydrogen-rich water preparation device. First, as an intermediate storage container, it balances the flow rate of the hydrogen-water mixture and cutting efficiency during the cutting process, avoiding system overload or underload caused by continuous cutting. Second, through a flexible recirculation mechanism, the gas-water storage tank 9 enables the system to customize cutting according to product requirements and production conditions, thereby meeting the varying demands for hydrogen-rich water quality in different application scenarios.

[0056] Furthermore, the gas-water storage barrel 9 not only serves as a temporary storage and recycling container for the hydrogen-water mixture, but is also connected to the storage box 2 via the return water control valve 6, and the storage box 2 is purified by the water purifier 3. This connection path realizes the circulation and reuse of water resources through a pressure pump. When the gas-liquid mixing pump 7 mixes the purified raw water with hydrogen to form a hydrogen-water mixture, and after preliminary cutting by the first pressure cutter 4, the cut product is introduced into the gas-water storage barrel 9 for temporary storage. If it is decided not to directly export the hydrogen-water mixture for subsequent processing at this time, but to return it to the second pressure cutter 5 for more precise cutting, then a portion of residual water may be generated during the second pressure cutting process. This portion of residual water is controlled by the return water control valve 6 and is transported back to the storage box 2 under the action of the pressure pump.

[0057] In the storage tank 2, the recovered residual water is mixed with new raw water, ready for the next round of purification and hydrogen-rich water preparation process. Since the water in the storage tank 2 is recycled, it is necessary to ensure that the residual water does not introduce new sources of pollution before reuse. In order to achieve this goal, all recovered residual water will be purified again by the water purifier 3 to remove impurities or microorganisms that may be produced by the cutting process. In this way, this embodiment not only improves the utilization rate of water resources, but also reduces the environmental burden caused by wastewater discharge. At the same time, it ensures that the water quality in the hydrogen-rich water preparation process is always maintained in the best condition, ensuring the quality and safety of the final product. This water resource recovery and utilization mechanism is an important advancement in the sustainable development of the hydrogen-rich water preparation process.

[0058] In this embodiment, after the hydrogen-water mixture has undergone multiple rounds of alternating cutting by the first pressure cutter 4 and the second pressure cutter 5, and its bubble diameter and hydrogen solubility have met the relevant production task or process indicators, the operator can control the valves and piping system to direct the hydrogen-water mixture stored in the gas-water storage tank 9 to the storage tank 11. To achieve this transfer process, a pressure pump is specially provided to pump the hydrogen-water mixture from the gas-water storage tank 9 to the storage tank 11.

[0059] The storage tank 11, serving as a storage container for the finished hydrogen-rich water, has sufficient capacity to hold the prepared hydrogen-rich water and ensure its stability and safety during storage. The storage tank 11 must be made of conventional materials with good sealing, pressure resistance, and corrosion resistance to ensure that the hydrogen-rich water is not contaminated or affected by the external environment during long-term storage.

[0060] Furthermore, the storage tank 11 is also equipped with a low water level sensor 111 and a high water level sensor 112 for detecting the water level.

[0061] Preferably, the storage barrel 11 is also equipped with a water outlet valve 113 for discharging water, and a meter 114 is used for measuring the water.

[0062] In this embodiment, all electrical components of the device as a whole rely on AC power for energy supply; specifically, the electrical components of the device as a whole are conventionally electrically connected to the AC power output port through devices such as relays, transformers and button panels to meet the energy supply requirements of all electrical components of the device.

[0063] In this embodiment, a controller is further provided on the outside of the device, which is used to connect and control all electrical components of the device as a whole to be driven according to a pre-set program as a preset value and drive mode; it should be pointed out that the above-mentioned drive mode corresponds to the corresponding start-stop time interval, speed, power and other output parameters between the relevant electrical components mentioned above, that is, it meets the requirements of the relevant electrical components mentioned above to drive the relevant mechanical devices to operate according to the functions described therein.

[0064] Preferably, the controller is a PLC controller, which completes the above control requirements through conventional PLC control modes such as ladder diagrams, sequential function charts, function block diagrams, instruction tables or structured texts; it should be pointed out that the operating parameters of the electrical components or other power components driven by its programming are non-limiting; specifically, the relevant drive control is adjusted according to actual usage requirements.

[0065] The above-described embodiments merely represent implementation methods for the relevant practical applications of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
