Description

Technical Field

[0001] The invention relates to the technical field of atomization equipment, in particular to a constant-temperature atomization device for heating sterile injection water. Background Art

[0002] Sterile water for injection serves as the core solvent in nebulized inhalation therapy. Its high purity and isotonic properties ensure stable drug dissolution while preventing airway mucosal edema. The nebulizer disperses the drug solution into tiny particles, which act directly on the respiratory mucosa, exerting therapeutic effects such as antispasmodic, antiasthmatic, expectorant, and anti-inflammatory. It is particularly suitable for diluting hypertonic drugs and for children and mechanically ventilated patients.

[0003] The atomization of sterile water for injection places stringent demands on the stability, cleanliness, and temperature control accuracy of the atomization equipment. However, conventional atomization devices present numerous challenges that severely hinder the application of heated, constant-temperature atomization of sterile water for injection. In particular, the timing and volume of fluid infusion cannot be precisely controlled, and atomization can be easily interrupted due to insufficient fluid levels.

[0004] Traditional atomization devices mostly use float valves or electrode-type liquid level detection, which have slow response speeds and are prone to false triggering when the liquid level fluctuates, making it impossible to accurately control the timing and amount of fluid replenishment.

[0005] Liquid level detection in a float valve is based on the mechanical principle that a float moves the valve core as the liquid level rises and falls. However, the float valve cannot react immediately to changes in the liquid level, resulting in a significant lag. As the liquid level drops, the float valve may not be able to detect the change in time, opening the refill channel before the liquid level drops to a dangerous threshold, resulting in interrupted atomization.

[0006] During the atomization process, liquid levels inevitably fluctuate due to various factors, such as equipment vibration, impact of the fluid in the pipeline, and interference from the external environment. The float will rise and fall with these fluctuations, causing the valve core to move frequently. This can cause the float valve to open and close the replenishment channel multiple times before the liquid level reaches the critical point where replenishment is needed or stopped, making it impossible to accurately control the replenishment volume.

[0007] In addition, the atomizer of the traditional atomization device needs to be manually disassembled and cleaned regularly, which can easily introduce contamination during the operation, and frequent disassembly leads to increased component wear.

[0008] During manual disassembly and installation, dust, microorganisms, and other pollutants in the air can easily adhere to the surface of the atomizer or enter the device. These pollutants can not only clog the tiny pores in the atomizer, reducing atomization efficiency, resulting in reduced atomization volume and uneven atomization particles, but can also breed bacteria, affecting the purity of the atomized liquid and endangering patient health.

[0009] Frequent disassembly and installation can cause loosening and wear of connections between components, degrading sealing performance and potentially leading to problems such as liquid leakage. Furthermore, repeated mechanical friction accelerates the wear of the atomizer surface coating, causing a gradual decline in atomization performance, shortening service life, and increasing equipment maintenance costs and replacement frequency. Summary of the Invention

[0010] The purpose of the present invention is to provide a device for heating and constant-temperature atomization of sterile injection water to solve the problems raised in the above-mentioned background technology.

[0011] The main design ideas of the present invention are: When using sterile water for injection for heated, constant-temperature atomization, conventional atomizers present numerous problems, hindering their widespread adoption. Traditional atomizers often use float valves for liquid level detection. These valves exhibit significant hysteresis and are susceptible to frequent valve movement due to liquid level fluctuations. This makes it impossible to accurately detect and control the timing and volume of fluid infusion, leading to interruptions in atomization.

[0012] To this end, it is envisaged to improve the sterile water for injection heating and constant temperature atomization device. Specifically, the buoyancy ball assembly is improved to overcome the problems of traditional buoyancy balls due to hysteresis and susceptibility to interference from liquid level fluctuations. It can quickly respond to liquid level changes and accurately capture the timing of fluid infusion. When the liquid level drops to the fluid infusion threshold, the water injection valve drive assembly is driven to automatically open the water injection valve and deliver the added liquid through the fluid infusion assembly. After the fluid infusion is completed, the buoyancy ball assembly moves in the opposite direction to synchronously close the water injection valve and the fluid infusion assembly. Automatic and precise fluid infusion control without human intervention is achieved, ensuring that the amount of liquid in the atomization device is always within the appropriate range, providing a stable and continuous liquid supply for the atomization work, and ensuring the quality and efficiency of atomization.

[0013] On this basis, improvements have been made to the cleaning of the atomizer disc to address the pain point of the transmission atomizer device requiring manual disassembly and cleaning of the atomizer disc. A roller brush assembly is installed on the rehydration component. During the rehydration process, as the rehydration component moves up and down to replenish the fluid, it will simultaneously drive the roller brush assembly to roll and clean the atomizer disc. This achieves the simultaneous rehydration and cleaning process, eliminating the need for manual intervention or equipment disassembly, and can complete the atomizer disc cleaning task in a timely and efficient manner, ensuring that the atomizer disc is always in optimal working condition and providing reliable protection for the stable operation of the device.

[0014] To achieve the above object, the present invention provides the following technical solutions: The present invention provides a device for heating and constant temperature atomization of sterile injection water, comprising an atomization box, a water injection valve provided on the top of the atomization box, a breathing mask connected to the side wall thereof, and further comprising: The buoyancy ball assembly is floated on the liquid surface in the atomization box The water injection valve drive assembly is arranged in the atomizing box, one end of which is installed below the buoyancy ball assembly and the other end is connected to the water injection valve; The liquid replenishing component is arranged in the atomizing box and is connected to the water outlet end of the water injection valve. The water injection valve is opened by the water injection valve driving component to replenish liquid into the atomizing box.

[0015] The buoyancy ball assembly includes a square frame, inside which four first buoyancy balls are arranged. The four first buoyancy balls are arranged on two diagonals of the square frame. A second buoyancy ball is arranged at the center of the square frame, and the size of the second buoyancy ball is larger than that of the first buoyancy ball. The second buoyancy ball and the first buoyancy ball and the first buoyancy ball and the square frame are connected by ball joints.

[0016] In order to open or close the water injection valve, it is further preferred that the water injection valve drive assembly includes: A vertical transmission member, the lower end of which is elastically connected to the bottom of the atomizer box and is located below the buoyancy ball assembly, and the upper end of which is equipped with a first rack; One end of the transverse transmission member is engaged with the first rack, and the other end is connected to the water injection valve.

[0017] In order to automatically and accurately perform fluid refilling, it is further preferred that the fluid refilling component includes: A pulley shaft is arranged on the side wall of the atomization box; The pulley is mounted on the pulley shaft and rotates along the circumference of the pulley shaft, with a flexible rope wound around it; A counterweight connected to one end of the flexible cable; The liquid replenishing component is connected to the other end of the flexible rope, and the water inlet of the liquid replenishing component is connected to the water outlet of the water filling valve.

[0018] In order to lock or release the fluid infusion assembly, further preferably, the ratchet assembly includes: a ratchet, fixedly connected to a side wall of the pulley; A pawl is provided on the side wall of the atomizer box and engages with the ratchet wheel; A pawl transmission member, one end of which is placed below the buoyancy ball assembly and the other end of which is connected to the pawl, for driving the pawl to disengage from the ratchet wheel; The stop claw is arranged on the side wall of the atomizer box and is used to drive the pawl to engage with the ratchet wheel.

[0019] The specific process of the liquid replenishing component opening the water injection valve through the water injection valve driving component to replenish liquid into the atomizing box is as follows: After the atomization application starts, the buoyancy ball assembly descends to the first warning position and contacts the ratchet transmission component, and drives the ratchet transmission component to open the liquid replenishing component; Initially, the weight of the liquid replenishing member is less than the weight of the counterweight member, and the liquid replenishing member slides upward to the water outlet end of the water injection valve and is connected to the water outlet end of the water injection valve; The buoyancy ball assembly continues to descend to the second warning position and contacts the water injection valve drive assembly, and drives the water injection valve drive assembly to open the water injection valve; After the water injection valve is opened, the liquid replenishing component starts to replenish liquid. When the weight of the replenished liquid and its own weight is greater than the weight of the counterweight, the liquid replenishing component slides downward and disconnects from the water injection valve. The liquid replenishing piece slides to the bottom of the atomizer box to discharge the replenished liquid; The buoyancy ball assembly begins to rise, the water injection valve drive assembly drives the water injection valve to close, and the stop claw drives the liquid replenishment assembly to close.

[0020] In order to clean the atomization module in time, it is further preferred that a rolling brush assembly is further included, which is arranged on the counterweight and is used for rolling cleaning of the atomization module.

[0021] Further preferably, the roller brush assembly includes: A roller brush is arranged on the counterweight; The roller brush transmission part is connected to the counterweight part and is used to drive the counterweight part to rotate circumferentially.

[0022] In order to uniformly heat the liquid in the atomizing box, it is further preferred that a stirring component is further included, which is arranged in the atomizing box and is used to stir the liquid in the atomizing box.

[0023] The stirring assembly comprises: A stirring element, one end of which is located in the liquid, with a plurality of stirring blades arranged on its surface along its axial direction, and the other end of which is connected to the water outlet end of the water injection valve; The stirring driving member is arranged at the other end of the stirring member and is communicated with the water outlet end of the water injection valve, and is used for driving the stirring member to rotate circumferentially along its axis.

[0024] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a heated, constant-temperature atomizer for sterile water for injection. Through the efficient collaboration of a buoyancy ball assembly, a water injection valve drive assembly, and a fluid infusion assembly, this device establishes an automated, precise fluid infusion control system. This system can sense and automatically adjust the fluid level within the atomizer in real time, achieving precise replenishment and dynamic balancing without manual intervention, ensuring the fluid level is consistently maintained within the optimal operating range.

[0025] 2. The present invention incorporates a roller brush assembly in addition to the rehydration assembly. As the rehydration assembly moves up and down, the roller brush assembly simultaneously performs comprehensive rolling cleaning of the atomizer module. This enables simultaneous rehydration and cleaning. Its self-cleaning closed-loop system completely eliminates the risk of cross-contamination introduced by manual maintenance. Without manual intervention or equipment disassembly, the atomizer module can be cleaned promptly and efficiently, ensuring the atomizer is always in optimal working condition.

[0026] 3. The present invention also incorporates a stirring assembly at the outlet of the water injection valve. This utilizes the potential energy of the liquid after the valve is opened to drive the stirring element, stirring the liquid in the atomization chamber in all directions. This ensures more even heating of the liquid, preventing uneven heating and temperature stratification in the upper and lower layers of liquid, which can affect the atomization effect. This self-driven stirring mechanism requires no external power source or manual intervention, significantly improving the safety and reliability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0030] Example 1 like Figures 1 to 4As shown, this embodiment provides a sterile injection water heating and constant temperature atomization device, including a nebulizer box 10, a water injection valve 101 is fixedly provided on the top, a breathing mask 102 is connected to the side wall, and a buoyancy ball assembly is floated on the liquid surface in the nebulizer box 10; a water injection valve drive assembly is arranged in the nebulizer box 10, one end of which is installed below the buoyancy ball assembly, and the other end is connected to the water injection valve 101; a fluid replenishment assembly is arranged in the nebulizer box 10, connected to the water outlet end of the water injection valve 101, and the water injection valve drive assembly opens the water injection valve 101 to transport the replenished liquid into the nebulizer box 10; the fluid replenishment assembly also includes a ratchet assembly, one end of which is installed below the buoyancy ball assembly, and the other end is connected to the fluid replenishment assembly.

[0031] In a specific implementation, the nebulizer box 10 is made of high-strength, corrosion-resistant medical-grade materials, such as medical-grade 316L stainless steel, to ensure that the stored sterile water for injection is not contaminated and can withstand the various pressure and temperature changes during operation. The nebulizer box 10 has an ergonomic design for easy placement and operation in a medical environment, such as a cylindrical or square structure.

[0032] The interior of the nebulizer box 10 is divided into two upper and lower compartments. The upper compartment is the liquid storage compartment 103, which is used to store sterile injection water for nebulization to ensure that the water is pure and the supply is stable; the lower compartment is the nebulizer compartment 104, which is used to store the nebulized liquid and heat the nebulized liquid at a constant temperature to provide support for the nebulization application. The water injection valve 101 is set on the partition between the liquid storage compartment 103 and the nebulizer compartment 104, and can be connected to the liquid storage compartment 103 and the nebulizer compartment 104 respectively, and is used to transport the sterile injection water in the liquid storage compartment 103 to the nebulizer compartment 104. The side of the partition that contacts the liquid storage compartment 103 is a curved surface structure. In order to facilitate the flow of sterile injection water to the water injection valve 101, the water injection valve 101 is set at the lowest point of the curved surface structure.

[0033] A water inlet is provided on the top of the liquid storage chamber 103, and sterile water for injection can be added to the liquid storage chamber 103. The side wall of the atomization chamber 104 is connected to an atomization tube 105, and the other end of the atomization tube 105 is connected to a breathing mask 102. During atomization application, the breathing mask 102 is worn on the patient's face for atomization treatment. A control panel 106 is provided on the side wall of the atomization box 10 for accepting control instructions input by the user and displaying relevant working parameters of the atomization application. For example, the user inputs the start and stop instructions of the atomization device, the temperature range of the liquid heating, the atomization time, the atomization intensity, etc. The control panel 106 is connected to the controller, and the controller is fixedly arranged on the rear side wall of the atomization box 10.

[0034] As a specific implementation, the main controller 12 can utilize the BROADCOM BCM2711 quad-core Cortex-A72 (ARM V8) 64-bit system-on-chip (SoC). It operates at a 1.5GHz clock speed, features 4GB of RAM, and supports multiple storage interfaces for easy storage expansion. The BCM2711 offers a rich set of peripheral interfaces, including GPIO, HDMI, SPI, USB, PCIe, Ethernet, Wi-Fi, and Bluetooth. The BCM2711 integrates a power management unit (PMU) that manages chip power and also provides power to peripherals. The operating power supply has a wide input voltage range of 5 to 34V, an adjustable DC output voltage between 2 and 28V, and an output current of 12A. Interface expansion circuitry can provide multiple RS485 and RS232 interfaces.

[0035] A heating module 107 is fixed to the bottom of the atomization chamber 104 to heat the atomized liquid. Heating module 107 uses a PTC heating element, such as the Heraeus HP100-M, with a power output of 8W to 15W and an operating temperature of 80°C to 150°C. Its titanium alloy housing supports IP67 waterproofing. During atomization, the liquid is heated to a constant temperature of 37°C (human comfort temperature) with an error of ≤±1°C. Heating module 107 is electrically connected to a controller, which issues specific temperature adjustment instructions to heating module 107.

[0036] A plurality of temperature sensors are installed on the side wall of the atomization chamber 104 for real-time collection of the temperature of the atomized liquid. Specifically, the temperature sensor adopts a DS18B20 digital temperature sensor and outputs a digital signal. The sampling frequency is 10Hz, the temperature measurement range is -55℃~+125℃, and the accuracy is ±0.5℃. The programmable resolution is 9 to 12 bits, the operating voltage is DC5.5V, and a single bus interface is supported. Duplex communication can be achieved with one data line. Multiple temperature sensors are electrically connected to the controller to transmit the collected real-time liquid temperature to the controller.

[0037] The inner wall of the atomizer tube 105 is equipped with an end-tidal carbon dioxide (EtCO2) monitoring device for real-time monitoring of the partial pressure and concentration of carbon dioxide in the patient's exhaled alveolar gas. EtCO2 is a key indicator of the body's ventilation function. For example, the CM2201, based on a non-dispersive infrared monitoring principle, offers a measurement range of 0-150 mmHg (0-20.0% volume ratio) and a respiratory rate range of 0-150 breaths / minute with an accuracy of ±1 breath / minute, meeting the monitoring needs of patients of all ages. It features a sampling frequency of 100Hz, an operating temperature and humidity range of 0°C-45°C, and 10%-90% RH (non-condensing), and output parameters including CO2 concentration (mmHg), end-tidal CO2, exhaled CO2, and respiratory rate. RS232 serial communication is supported. The device is electrically connected to the controller to transmit the collected real-time EtCO2 information to the controller.

[0038] Atomizer module 108 is located at the water inlet of atomizer tube 105 to atomize the atomized liquid. Atomizer module 108 utilizes a piezoelectric ceramic atomizer with an atomization rate of 0.1 ml / min to 5 ml / min, an operating frequency of 100 kHz to 200 kHz, and a micropore size of 1 μm to 10 μm. Atomizer module 108 is electrically connected to a controller, which issues specific start / stop and atomization commands to atomizer module 108.

[0039] It should be noted that the buoyancy ball assembly is floated on the surface of the liquid in the atomizing chamber 104 and is used to detect changes in the liquid level. It moves synchronously with the rise or fall of the liquid level. The water injection valve drive assembly is disposed in the atomizing chamber 104 and controls the water injection valve drive assembly to open or close the water injection valve 101 by the movement of the buoyancy ball assembly. The fluid replenishment assembly is disposed in the atomizing chamber 104 and is used to transport replenished liquid into the atomizing chamber 104. When the buoyancy ball assembly descends, the fluid replenishment assembly is opened. After the fluid replenishment is completed, the fluid replenishment assembly is closed.

[0040] The overall usage process is: 1. When the atomization application begins, the liquid in the atomization chamber 104 gradually decreases, and the buoyancy ball assembly drops synchronously with the liquid level; 2. After the buoyancy ball assembly descends to the first warning position, it contacts the lower end of the ratchet assembly and further drives the ratchet assembly to descend. The descent of the ratchet assembly drives the fluid infusion assembly to open; 3. After the liquid replenishing component is opened, its water inlet is connected to the water outlet of the water filling valve 101, and liquid is ready to be replenished from the water filling valve 101; 4. The buoyancy ball assembly continues to descend to the second warning position and contacts the lower end of the water injection valve drive assembly, further driving the water injection valve drive assembly to descend. The descent of the water injection valve drive assembly drives the water injection valve 101 to open; 5. After the water injection valve 101 is opened, the liquid replenishing component starts to replenish liquid. When the replenished liquid reaches the set threshold, the replenished liquid is discharged into the atomization chamber 104, and the buoyancy ball component rises synchronously with the liquid level; 6. After the buoyancy ball assembly begins to rise, the water injection valve 101 is driven to close by the self-resetting elastic force of the water injection valve drive assembly; 7. The buoyancy ball assembly continues to rise and passes the first warning position and then separates from the ratchet assembly. The rehydration assembly is driven to close by the self-resetting elastic force of the ratchet assembly.

[0041] Example 2 like Figures 1 to 15 As shown, based on Example 1, this embodiment provides a sterile injection water heating and constant temperature atomization device, the buoyancy ball assembly adopts a symmetrical multi-sphere layout structure, including a square frame 111, four first buoyancy balls 112 are arranged inside, the four first buoyancy balls 112 are arranged on the two diagonals of the square frame 111, and a second buoyancy ball 113 is arranged at the center of the square frame 111, and the size of the second buoyancy ball 113 is larger than the size of the first buoyancy ball 112, and the second buoyancy ball 113 and the first buoyancy ball 112 and the square frame 111 are connected by ball joints.

[0042] It should be noted that the four first buoyancy balls 112 are distributed diagonally in space, forming a double rotationally symmetrical structure, which effectively suppresses the torsional vibration of the square frame 111 outside the plane; the central second buoyancy ball 113 and the four first buoyancy balls 112 form a five-sphere concentric system, optimizing the overall center of gravity configuration through the mass-buoyancy gradient distribution. The ball hinge connection uses a self-lubricating polymer bushing, allowing a ±15° tilt angle and 360° rotational freedom. The double ball hinge transmission mechanism realizes torque vector decomposition, ensuring that each buoyancy unit maintains dynamic balance in 6-degree-of-freedom movement. The size gradient design enables the central second buoyancy ball 113 to bear 60% of the basic buoyancy, and the four outer first buoyancy balls 112 provide attitude fine-tuning capabilities.

[0043] The bottom of the atomizing chamber 104 is vertically symmetrically provided with four sliding bars along the outside of the square frame 111. Each sliding bar is provided with a slider, which is fixedly connected to the outer wall of the square frame 111. The buoyancy ball assembly can slide freely vertically along the sliding bar for horizontal position limiting. A water level detector 114 is connected to one side of the square frame 111. The water level detector 114 is electrically connected to the controller for real-time collection of liquid level data and transmission to the controller. An observation window is provided on the side wall of the atomizing box 10 near the water level detector 114. Medical staff can view the liquid level data collected by the water level detector 114 through the observation window outside the atomizing box 10.

[0044] The water injection valve drive assembly includes a vertical transmission member and a horizontal transmission member. The lower end of the vertical transmission member is elastically connected to the bottom of the atomizer box 10 and is located below the buoyancy ball assembly. A first rack 121 is mounted on the side wall of the upper end. One end of the horizontal transmission member is engaged with the first rack 121, and the other end is rotatably connected to the water injection valve 101. Specifically, the water injection valve drive assembly is disposed within the atomizer chamber 104 and is used to open or close the water injection valve 101.

[0045] As a specific embodiment, vertical transmission member includes a first torsion spring 122, which is vertically arranged on the bottom of atomizing chamber 104. The other end of the first torsion spring 122 is connected with a first connecting rod 123, and the first connecting rod 123 is an L-shaped structure. The other end of the first torsion spring 122 is connected with the corner of the first connecting rod 123L-shaped structure, and the specific connection point is located at the outer surface of the corner and on a side of the vertical section axis colinear with it. The horizontal section of the first connecting rod 123L-shaped structure is located below one end of square frame 111. The first rack 121 is vertically arranged on the sidewall of the free end of the vertical section of the first connecting rod 123L-shaped structure.

[0046] The transverse transmission assembly includes a first gear 124, which forms a gear-rack meshing pair with the first rack 121. The gear shaft of the first gear 124 is rigidly connected to one end of a second connecting rod 125 via a rigid coaxial connection. The second connecting rod 125 is arranged transversely along a horizontal reference plane, and its other end is connected to the valve stem of the water injection valve 101 via an articulated joint, forming a revolving pair. A valve stem travel of 0° to 90° corresponds to a fully closed to fully open state.

[0047] In operation, when the buoyancy ball assembly descends to the second warning line and contacts the horizontal section of the first connecting rod 123, compressing the first torsion spring 122 and driving the first connecting rod 123 and the first rack 121 to move downward synchronously. The downward movement of the first rack 121 drives the first gear 124 meshing with it to begin circumferential rotation, and simultaneously drives the second connecting rod 125 to rotate circumferentially, thereby opening the water injection valve 101 through the valve stem.

[0048] When the buoyancy ball assembly begins to rise with the liquid level, the first connecting rod 123 and the first rack 121 are pushed upward synchronously by the restoring elastic force of the first torsion spring 122. The upward movement of the first rack 121 drives the first gear 124 meshing with it to rotate in the opposite direction, and simultaneously drives the second connecting rod 125 to rotate in the opposite direction, thereby closing the water injection valve 101 through the valve stem.

[0049] The rehydration assembly includes a pulley shaft 131, which is fixedly arranged on the side wall of the atomizer box 10; a pulley 132, which is sleeved on the pulley shaft 131 and rotates circumferentially along the pulley shaft 131, and a flexible rope 133 is wound around it; a counterweight 134, which is connected to one end of the flexible rope 133; and a rehydration member 135, which is connected to the other end of the flexible rope 133, and its water inlet is connected to the water outlet end of the water injection valve 101.

[0050] As a specific embodiment, the pulley shaft 131 is horizontally fixedly arranged inside the atomization chamber 104, and pulleys 132 are provided at both ends. A flexible cable 133 is wound around each pulley 132, and the pulley 132 drives the flexible cable 133 to rotate synchronously along the axial direction of the pulley shaft 131. The flexible cable 133 is made of a high-strength, corrosion-resistant flexible material. One end of the flexible cable 133 is connected to a counterweight 134 near the side wall of the atomization chamber 104, and the other end is connected to a fluid replenishing component 135. The counterweight 134 and the fluid replenishing component 135 are both arranged horizontally, and the weight of the counterweight 134 is greater than the weight of the fluid replenishing component 135.

[0051] The counterweight 134 is made of 304 stainless steel and is specifically a rod-shaped structure. Both ends are sleeved with collars, and the flexible rope 133 is fixedly connected to the collars. The fluid replenishing piece 135 is a square strip structure with an internal hollow top opening for conveniently storing the replenished liquid. The fluid replenishing piece 135 is vertically mounted with a second rack 136 on the side wall away from the counterweight 134. The bottom surface of the atomizing chamber 104 is symmetrically provided with two dumping side blocks 138. When the fluid replenishing piece 135 moves to the bottom of the atomizing chamber 104 and contacts with the dumping side blocks 138, the dumping side blocks 138 drive the fluid replenishing piece 135 to discharge the replenished liquid.

[0052] The outlet of the water inlet valve 101 is connected to a liquid conduit, which is arranged at an angle to facilitate liquid outflow. The outlet of the conduit communicates with the liquid infusion chamber of the liquid infusion component 135. A liquid infusion valve 137 is installed at the outlet of the conduit to control the flow of liquid into the liquid infusion chamber of the liquid infusion component 135. Liquid infusion valve 137 utilizes a ball valve structure, with a valve stem travel of 0° to 90°, corresponding to a fully closed to fully open state.

[0053] The valve stem of the rehydration valve 137 is rotatably connected to the third connecting rod, which penetrates the sidewall of the catheter and is sealed thereto, for example, using a double O-ring and graphite packing composite seal. The other end of the third connecting rod is axially locked to the slave pulley via a spline coupling. The second rack 136 meshes with a second gear, whose shaft is coaxially connected to the primary pulley via a locking sleeve. A highly elastic timing belt is installed between the primary and secondary pulleys.

[0054] In operation, when the fluid infusion component 135 moves upward, the second rack 136 drives the second gear and the main pulley to rotate synchronously, which in turn is driven by the synchronous belt to rotate the slave pulley. The rotation of the slave pulley, through the third connecting rod, drives the valve stem to rotate 90 degrees forward, opening the fluid infusion valve 137. When the fluid infusion component 135 moves downward, it drives the second gear and the main pulley to rotate in the opposite direction, which in turn is driven by the synchronous belt to rotate the slave pulley in the opposite direction, driving the valve stem to rotate 90 degrees in the opposite direction, closing the fluid infusion valve 137.

[0055] The ratchet assembly includes a ratchet 141, which is fixedly connected to the side wall of the pulley 132; a pawl 142, which is arranged on the side wall of the atomizer box 10 and engages with the ratchet 141; a pawl transmission member, one end of which is placed below the buoyancy ball assembly and the other end is connected to the pawl 142, used to drive the pawl 142 to disengage from the ratchet 141; a stop pawl 143, which is arranged on the side wall of the atomizer box 10 and is used to drive the pawl 142 to engage with the ratchet 141.

[0056] As a specific embodiment, ratchet 141 is coaxially arranged with pulley 132 and is fixedly connected with the outer sidewall of pulley 132.One end of ratchet 142 is arranged on the sidewall of atomizing chamber 104, and its working end is engaged with ratchet 141. Ratchet transmission member comprises the fourth connecting rod 144, and the fourth connecting rod 144 is vertically arranged, and its upper end is fixedly connected with the outer sidewall of ratchet 142 working ends, and the lower end is fixedly connected with floating member 145. Floating member 145 is horizontally arranged, and its other end is positioned at the below of square frame 111.One end of stop pawl 143 is arranged on the sidewall of atomizing chamber 104, and its working end is positioned at the below of ratchet 142 working ends.The connecting end of stop pawl 143 is provided with spring, can rely on the elastic force of spring to drive its working end to move up and down.

[0057] In operation, when the buoyancy ball assembly descends along with the liquid level, it contacts the floating member 145 and drives it to descend synchronously, thereby driving the pawl 142 to disengage the ratchet 141 through the fourth connecting rod 144. When the buoyancy ball assembly rises along with the liquid level and leaves the floating member 145, the restoring elastic force of the stop pawl 143 drives the pawl 142 to engage with the ratchet 141 again.

[0058] The atomizing device also includes a roller brush assembly mounted on the counterweight 134, which is used to perform rolling cleaning on the atomizing module 108 of the atomizing device as the counterweight 134 moves up and down. It should be noted that the water inlet of the atomizing tube 105 is positioned near the counterweight 134 to facilitate cleaning of the atomizing module 108. The roller brush assembly includes a roller brush 151 mounted on the counterweight 134, and a roller brush transmission member connected to the counterweight 134 to drive the counterweight 134 to rotate circumferentially along its axis.

[0059] As a specific embodiment, the roller brush 151 is sleeved at the center of the counterweight 134 and rotates synchronously with the counterweight 134. The surface of the roller brush 151 is provided with flexible bristles, and the bristles are made of high-temperature resistant and corrosion-resistant medical silicone material. The roller brush transmission member includes a third gear 152, and a third gear 152 is provided at both ends of the counterweight 134. The two third gears 152 are arranged symmetrically along the axis of the counterweight 134 and are located on the inner side of the collar. The third gear 152 can rotate along the axis of the counterweight 134. The third gear 152 is engaged with a third rack 153, and the third rack 153 is arranged vertically, with the bottom end connected to the bottom of the atomizing chamber 104 and the top end connected to the side wall of the atomizing chamber 104.

[0060] During specific operation, when the counterweight 134 moves downward, the roller brush transmission member drives the counterweight 134 and the roller brush 151 to rotate circumferentially, and then the roller brush 151 is used to perform rolling cleaning on the atomization module 108; when the counterweight 134 moves upward, the roller brush transmission member also drives the counterweight 134 and the roller brush 151 to rotate circumferentially, and performs rolling cleaning on the atomization module 108.

[0061] Example 3 like Figures 1 to 15 As shown, based on Example 2, this embodiment provides a sterile injection water heating constant temperature atomization device, which also includes a stirring assembly, which is arranged in the atomization chamber 104 and is used to stir the liquid in the atomization chamber 104 so that the liquid is heated more evenly. The stirring assembly includes a vertically arranged stirring member 161, the upper end of which is connected to the water outlet end of the water injection valve 101, and the lower end is located in the liquid, and a plurality of stirring blades are axially arranged on its surface; a stirring drive member, which is arranged at the other end of the stirring member 161 and is connected to the water outlet end of the water injection valve 101, and is used to drive the stirring member 161 to rotate circumferentially along its axis. The stirring drive member includes a turbine blade 162, which is fixedly connected to the upper end side wall of the stirring member 161; a guide pipe 163, which is arranged at the water outlet end of the water injection valve 101 and is connected to the water outlet end of the water injection valve 101, and is used to guide the liquid to flow to the turbine blade 162 and drive the turbine blade 162 to rotate.

[0062] During specific operation, when the liquid replenishment valve 101 needs to be opened, the liquid flows along the guide pipe 163 to the turbine blade 162 under the action of gravity, and the turbine blade 162 is driven to rotate under the impact of the liquid flow, and then the stirring element 161 is driven to rotate synchronously, and the stirring blades thereon are used to stir the atomized liquid in all directions to avoid uneven heating of the upper and lower layers of liquid and temperature stratification, which affects the atomization effect.

[0063] The specific clinical application process of the technical solution of the present invention is: 1. In the initial state, the counterweight 134 is close to the top side of the atomization chamber 104, and the liquid replenishing component 135 is close to the bottom side of the atomization chamber 104. When the atomization application begins, the liquid in the atomization chamber 104 gradually decreases, and the buoyancy ball assembly drops synchronously with the liquid level; 2. After the buoyancy ball assembly descends to the first warning position, the square frame 111 contacts the upper surface of the floating member 145, further driving the pawl transmission member to descend, thereby pulling the pawl 142 out of the ratchet wheel 141 to open the fluid infusion assembly; 3. After the fluid replenishment assembly is opened, the weight of the fluid replenishment component 135 is less than the weight of the counterweight 134, so the counterweight 134 moves downward and the fluid replenishment component 135 moves upward; 4. When the counterweight 134 moves downward, the roller brush transmission element drives the counterweight 134 and the roller brush 151 to rotate circumferentially, thereby rolling and cleaning the atomization module 108 through the roller brush 151; 5. As the rehydration member 135 moves upward, the second rack 136 drives the second gear and the main pulley to rotate synchronously, and in turn drives the timing belt, the slave pulley, the third connecting rod, and the valve stem to gradually open the rehydration valve 137, so that the rehydration chamber of the rehydration member 135 and the water outlet of the water injection valve 101 are fully connected; 6. After the buoyancy ball assembly continues to descend to the second warning position, the square frame 111 contacts the upper surface of the horizontal section of the first connecting rod 123, and further drives the vertical transmission member to move downward, thereby gradually opening the water injection valve 101 through the horizontal transmission assembly; 7. After the water injection valve 101 is opened, the liquid replenishing chamber of the liquid replenishing member 135 begins to be replenished with liquid. When the weight of the replenished liquid and the liquid replenishing member 135 itself is greater than the weight of the counterweight 134, the counterweight 134 begins to move upward, and the liquid replenishing member 135 moves downward. 8. After the water injection valve 101 is opened, the liquid also flows along the guide pipe 163 to the turbine blade 162, driving the turbine blade 162 to rotate, and then synchronously driving the stirring member 161 to rotate, using the stirring blades thereon to stir the atomized liquid in all directions; 9. When the counterweight 134 moves upward, the roller brush transmission element drives the counterweight 134 and the roller brush 151 to rotate circumferentially, and then the roller brush 151 rolls and cleans the atomization module 108 again; 10. As the rehydration member 135 moves downward, the second rack 136 drives the second gear and the main pulley to rotate in the opposite direction, and in turn drives the timing belt, the slave pulley, the third connecting rod, and the valve stem to gradually close the rehydration valve 137, so that the rehydration chamber of the rehydration member 135 and the water outlet of the water injection valve 101 are completely closed; 11. After the liquid replenishing component 135 moves downward to the bottom of the atomizing chamber 104, the liquid replenishing component 135 is driven to discharge the replenished liquid by tilting the side block 138, and the buoyancy ball assembly begins to rise synchronously with the liquid level; 12. When the buoyancy ball assembly rises above the second warning line, the square frame 111 separates from the first connecting rod 123, and the return elastic force of the first torsion spring 122 drives the vertical transmission member to move downward, thereby driving the horizontal transmission member to rotate in the opposite direction and gradually close the water injection valve 101; 13. When the buoyancy ball assembly continues to rise and crosses the first warning line, the square frame 111 separates from the floating member 145, and the restoring elastic force of the stop claw 143 drives the pawl 142 to re-engage with the ratchet wheel 141, closing the fluid infusion assembly.
