Description

Technical Field

[0001] This utility model relates to the field of ventilator technology, and in particular to a water tank module and a ventilator. Background Technology

[0002] Ventilators play a crucial role in the clinical care and daily relief of asthma patients. Asthma patients often experience discomfort such as wheezing, shortness of breath, chest tightness, and coughing due to problems such as airway spasm and dry mucous membranes. The ventilator, through its core functional module, uses a heater in the water tank to heat water, producing warm water vapor. Then, with the help of a fan, the warm water vapor is delivered to the user's airway, achieving airway humidification care.

[0003] Existing water tanks leak when tilted at an angle exceeding 30 degrees. Furthermore, the lack of optimized steam atomization in the design results in generally large droplet diameters in the output warm steam, making it difficult for the user's airway mucosa to effectively absorb the steam and thus hindering its ability to moisturize the airway and relieve symptoms, reducing the ventilator's efficiency. On the other hand, the excessively large droplet diameter also causes the steam to condense into liquid water during delivery to the user (e.g., a mask), leading to leaks and compromising the user experience. Utility Model Content

[0004] This utility model provides a water tank module to solve the problems of water leakage and poor user experience during water tank use.

[0005] This utility model discloses a water tank module, including a tank body, the tank body having an airflow inlet and an airflow outlet, and a heater being provided inside the tank body for heating water and generating water vapor; The airflow inlet and the airflow outlet are positioned on the tank body above the water level inside the tank body, and the height of the airflow outlet is greater than the height of the airflow inlet, while the diameter of the airflow outlet is smaller than the diameter of the airflow inlet.

[0006] Optionally, the housing includes a top cover, a shell, and a bottom shell arranged sequentially from top to bottom. The airflow inlet and the airflow outlet are located on the shell. The bottom shell forms a receiving groove. The heater is located at the bottom of the receiving groove. The receiving groove is connected to the airflow inlet and the airflow outlet.

[0007] Optionally, the airflow inlet and the airflow outlet are located at opposite ends on the same side of the housing.

[0008] Optionally, the height difference between the airflow inlet and the airflow outlet is 1cm to 5cm, and the height of the airflow inlet on the housing is 2cm to 5cm.

[0009] Optionally, the housing is further provided with a control component for adding water from an external water bottle into the receiving slot.

[0010] Optionally, the control component includes a valve plate, a control element, and a valve. The upper cover has a water inlet, and an external water bottle is disposed on the water inlet. The valve plate is disposed inside the upper cover and located at the water inlet. The valve plate has a first through hole and a second through hole. The first through hole is used to communicate with the water inlet. The control element is disposed inside the housing and is used to control the opening or closing of the first through hole, so that water from the water inlet can enter the receiving groove. The valve is disposed on the side of the upper cover away from the water inlet. The valve is disposed at the second through hole and is used to balance the pressure difference at the water bottle.

[0011] Optionally, a detection component is further provided inside the housing. The detection component includes a control circuit board and a first probe and a second probe disposed on the control circuit board. The control circuit board is disposed on the inner wall of the housing and electrically connected to the control component. The first probe and the second probe face the receiving groove and are used to measure the water level in the receiving groove. When the first probe detects that the water level is greater than a first preset water level, the control circuit board controls the control component to close the first through hole. When the second probe detects that the water level is less than a second preset water level, the control circuit board controls the control component to open the first through hole.

[0012] Optionally, the valve includes a valve body and a waterproof and breathable membrane disposed on one side of the valve body, the valve body is fixed to the upper cover, and the waterproof and breathable membrane is attached to the second through hole.

[0013] Optionally, a water inlet is provided on the side wall of the housing, and an external water bottle is provided on one side of the housing. The control component includes a water pipe and a control element. The water pipe passes through the water inlet to connect the external water bottle and the control element. The control element is used to inject water from the external water bottle into the receiving tank.

[0014] This utility model also discloses a ventilator, including the water tank module described above.

[0015] The beneficial effects of the water tank module and ventilator provided in this utility model embodiment are as follows: an airflow inlet and an airflow outlet are provided on the tank body. These two openings are channels for gas to flow inside the tank body. Inside the tank body, a heater is installed. The core function of the heater is to heat the water stored in the tank body. Through heating, the water is converted into water vapor. External airflow (such as the airflow generated by the fan in the ventilator) can enter the tank body through the airflow inlet, mix with the water vapor generated inside the tank body, and then flow out from the airflow outlet, and then be delivered to the user's airway. In the above process, the airflow inlet and outlet are positioned higher than the water level inside the tank. Even if the water tank module tilts at a certain angle during use, the water inside the tank cannot reach the airflow inlet and outlet, thus significantly reducing the probability of leakage and improving the stability of the water tank module in different usage scenarios. The airflow enters the tank from the larger airflow inlet and flows out along the smaller airflow outlet. During this process, the airflow speed at the outlet increases, which helps to disperse water vapor and reduce the droplet diameter. At the same time, the height of the airflow outlet is greater than the height of the airflow inlet. Larger droplets in the water vapor will settle to the lower part of the airflow outlet under the influence of gravity, while smaller droplets are output along the airflow outlet. These smaller droplets are more easily adsorbed and absorbed by the user's airway mucosa, which can fully play the role of moisturizing the airway and relieving symptoms such as wheezing and shortness of breath, thus improving the working efficiency of the ventilator. Secondly, smaller droplets are less likely to condense into liquid water during delivery, further reducing water leakage in the delivery path (such as the mask) and improving the user experience.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] This utility model embodiment provides a water tank module, such as Figures 1 to 8 As shown, the device includes a housing 10, which has an airflow inlet 101 and an airflow outlet 102. A heater 131 is installed inside the housing 10 to heat water and generate steam. The positions of the airflow inlet 101 and the airflow outlet 102 on the housing 10 are higher than the water level inside the housing 10, and the height of the airflow outlet 102 is greater than the height of the airflow inlet 101. The diameter of the airflow outlet 102 is smaller than the diameter of the airflow inlet 101.

[0020] An airflow inlet 101 and an airflow outlet 102 are provided on the housing 10. These two openings are channels for gas to flow inside the housing 10. A heater 131 is installed inside the housing 10. The core function of the heater 131 is to heat the water stored inside the housing 10. Through heating, the water is converted into water vapor. External airflow (such as the airflow generated by the fan in the ventilator) can enter the housing 10 through the airflow inlet 101, mix with the water vapor generated inside the housing 10, and then flow out from the airflow outlet 102, and then be delivered to the user's airway. In the above process, the air inlet 101 and air outlet 102 are positioned higher than the water level inside the tank 10. Even if the water tank module tilts at a certain angle during use, the water inside the tank 10 cannot reach the air inlet 101 and air outlet 102, thus significantly reducing the probability of leakage and improving the stability of the water tank module in different usage scenarios. The airflow enters the tank 10 from the larger air inlet 101 and flows out along the smaller air outlet 102. During this process, the airflow velocity at the air outlet 102 increases, which helps to dissipate water vapor. The smaller droplets disperse and reduce their diameter. Simultaneously, the height of the airflow outlet 102 is greater than the height of the airflow inlet 101, causing larger droplets in the water vapor to settle at the lower part of the airflow outlet 102, while smaller droplets are output along the airflow outlet 102. This makes them more easily adsorbed and absorbed by the user's airway mucosa, effectively moisturizing the airway and relieving wheezing and shortness of breath in asthmatic users, thus improving the ventilator's efficiency. Furthermore, the smaller droplets are less likely to condense into liquid water during delivery, further reducing water leakage in the delivery path (such as the mask) and improving the user experience.

[0021] As a preferred embodiment, refer to Figures 1 to 5 The housing 10 includes a top cover 110, a housing 120 and a bottom shell 130 arranged sequentially from top to bottom. An airflow inlet 101 and an airflow outlet 102 are located on the housing 120. The bottom shell 130 forms a receiving groove 1301. A heater 131 is located at the bottom of the receiving groove 1301. The receiving groove 1301 is connected to the airflow inlet 101 and the airflow outlet 102.

[0022] The enclosure 10 adopts a split design, consisting of three parts from top to bottom: the top cover 110, the shell 120, and the bottom shell 130. Each part is independently processed and then connected and fixed by bolts, buckles, etc. This split structure facilitates the assembly, disassembly, and subsequent maintenance of the enclosure 10.

[0023] The top cover 110 is the top component of the housing 10. The airflow inlet 101 and airflow outlet 102 are located on the housing 120, which clarifies their placement. Compared to placing them on the top cover 110 or the bottom shell 130, placing them on the housing 120 makes it easier to connect to external airflow delivery pipes (such as the fan outlet pipe of the ventilator and the air delivery pipe leading to the mask). At the same time, it can better match the water level design in the storage tank 1301, ensuring that both are above the water level, so that the water in the storage tank 1301 will not leak out from the airflow inlet 101 and the airflow outlet 102. The storage tank 1301 is the core area for storing water in the housing 10. The heater 131 is installed at the bottom of the storage tank 1301. This installation method allows the heater 131 to directly contact the water in the storage tank 1301, resulting in higher heat transfer efficiency and rapid heating of the water to the temperature that produces water vapor, reducing energy loss. Meanwhile, the receiving groove 1301 is connected to the airflow inlet 101 and the airflow outlet 102. This design ensures that the airflow entering through the airflow inlet 101 can flow over the receiving groove 1301 and fully mix with the water vapor generated by the heater 131 inside the receiving groove 1301. The mixed humid airflow then flows out from the airflow outlet 102. In this embodiment, the heater 131 uses existing devices, which are not specifically limited here, such as an electric heating element.

[0024] As a preferred embodiment, refer to Figure 1 The airflow inlet 101 and the airflow outlet 102 are located at opposite ends on the same side of the housing 120.

[0025] The air inlet 101 and the air outlet 102 are located on the same side, which is convenient for user operation and use. The air inlet 101 and the air outlet 102 are located at opposite ends on the same side, which makes the airflow path in the housing 120 longer and can cover most of the area above the receiving groove 1301. This means that during the flow, the airflow has a larger contact area and a longer contact time with the water vapor generated in the receiving groove 1301, and the mixing is more thorough. As a result, the gas delivered to the user end has a better humidification effect, which further enhances the user's experience.

[0026] As a preferred embodiment, the height difference between the airflow inlet 101 and the airflow outlet 102 is 1cm to 5cm, and the height of the airflow inlet 101 on the housing 120 is 2cm to 5cm.

[0027] The aforementioned height difference allows the airflow to form a reasonable upward flow path within the housing 10, and fully utilizes gravity and changes in airflow velocity to optimize the droplet refinement effect, thereby improving the user experience.

[0028] The height of the airflow inlet 101 on the housing 120, as defined above, refers to the distance from the lower edge of the airflow inlet 101 to the bottom of the housing 120. This inlet height of 2cm to 5cm provides sufficient safety margin for water level fluctuations. Even if the water tank module tilts slightly or experiences a brief rise in water level during filling, the water level is unlikely to reach the height of the airflow inlet 101, effectively preventing the risk of water leakage from the airflow inlet 101. This further enhances the leak-proof performance of the water tank module, ensuring user safety and cleanliness during use.

[0029] As a preferred embodiment, refer to Figures 2 to 8 The housing 10 is also equipped with a control component, which is used to add water from the external water bottle 20 into the receiving tank 1301, thereby improving the user's convenience.

[0030] As a preferred embodiment, the housing 10 is further provided with a control component, which includes a valve plate 310, a control element 320, and a valve 330. The upper cover 110 forms a water inlet 103, and an external water bottle 20 is provided on the water inlet 103. The valve plate 310 is located inside the upper cover 110 and at the water inlet 103. The valve plate 310 has a first through hole 3101 and a second through hole 3102. The first through hole 3101 is used to communicate with the water inlet 103. The control element 320 is located inside the housing 120 and is used to control the opening or closing of the first through hole 3101, so that the water flowing into the water inlet 103 can enter the receiving groove 1301. The valve 330 is located on the side of the upper cover 110 away from the water inlet 103 and is located at the second through hole 3102, which is used to balance the pressure difference at the water bottle 20.

[0031] The top cover 110 is equipped with a water inlet 103, allowing users to easily add water to the housing 10. Water flows along the shell 120 into the receiving groove 1301, where it is heated by the heater 131 to generate steam. A first through-hole 3101 on the valve plate 310 connects to the water inlet 103. When the housing 10 needs water replenishment, the control element 320 opens, allowing water from the external water bottle 20 to flow into the receiving groove 1301 through the water inlet 103 and the first through-hole 3101. The water is heated by the heater 131 to generate steam. Simultaneously, when the water level in the receiving groove 1301 reaches the required level, the control element 320 closes, cutting off the water supply and preventing overflow. A valve 330 connects to a second through-hole 3102, balancing the pressure difference inside the water bottle 20 to maintain stable internal and external pressure and ensure a continuous and smooth water supply. (Refer to...) Figures 2 to 6 When the water bottle 20 is located on top of the box 10, the control component 320 in this embodiment is a solenoid valve.

[0032] As a preferred embodiment, refer to Figure 3 and Figure 5 The housing 120 also includes a detection component 40, which includes a control circuit board 410 and a first probe 420 and a second probe 430 disposed on the control circuit board 410. The control circuit board 410 is disposed on the inner wall of the housing 120 and electrically connected to the control component 320. The first probe 420 and the second probe 430 face the receiving groove 1301 and are used to measure the water level in the receiving groove 1301. When the first probe 420 detects that the water level is greater than the first preset water level, the control circuit board 410 controls the control component 320 to close the first through hole 3101. When the second probe 430 detects that the water level is less than the second preset water level, the control circuit board 410 controls the control component 320 to open the first through hole 3101.

[0033] The detection component 40 is designed to automatically add water to the water tank module. Specifically, a control circuit board 410 electrically connected to the control component 320 is installed on the inner wall of the housing 120. The control circuit board 410 is equipped with a first probe 420 and a second probe 430 electrically connected to each other. The first probe 420 measures the water level in the accommodating tank 1301. When the first probe 420 detects that the water level is higher than the first preset water level, it indicates that sufficient water has been added to the accommodating tank 1301. Therefore, the control circuit board 410 controls the control component 320 to close the first through hole 3101 to prevent water from overflowing due to continued injection. When the second probe 430 detects that the water level is lower than the second preset water level, it indicates that the water in the accommodating tank 1301 is about to evaporate. At this time, the control circuit board 410 controls the control component 320 to open the first through hole 3101 and inject water into the accommodating tank 1301. This embodiment achieves on-demand water addition, improves water level control accuracy, and enhances equipment reliability. It provides users with safer and more reliable portable medical devices.

[0034] In this embodiment, the detection principle of the first probe 420 and the second probe 430 to detect the water level in the accommodating tank 1301 is existing technology and will not be described in detail here.

[0035] As a preferred embodiment, refer to Figure 4 The valve 330 includes a valve body 331 and a waterproof and breathable membrane 332 disposed on one side of the valve body 331. The valve body 331 is fixed to the upper cover 110, and the waterproof and breathable membrane 332 is attached to the second through hole 3102.

[0036] The valve body 331, serving as the basic frame of the valve 330, is fixedly mounted on the upper cover 110, providing a stable installation environment for the waterproof and breathable membrane 332. The waterproof and breathable membrane 332 is a core functional component, made of waterproof and breathable materials (such as polytetrafluoroethylene microporous membranes, eptfe membranes, etc.). Its pore size only allows gas molecules to pass through, while water molecules cannot. Specifically, during operation, when water in the water bottle 20 flows into the receiving tank 1301 through the inlet 103 and the first through-hole 3101, a negative pressure is formed inside the water bottle 20 due to the reduced water volume. At this time, the atmospheric pressure is greater than the internal pressure of the water bottle 20, and external air enters through the valve body 331 of the valve 330, passes through the waterproof and breathable membrane 332, and enters the inlet 103 through the second through-hole 3102, ultimately flowing into the water bottle 20. This achieves a balance of air pressure inside and outside the water bottle 20, ensuring a continuous and smooth water flow and preventing water outages caused by pressure imbalance, thus improving the reliability of the water supply.

[0037] As a preferred embodiment, refer to Figure 7 and Figure 8 The housing 120 has a water inlet 103 on its side wall and an external water bottle 20 on one side of the housing 120. The control assembly includes a water pipe 210 and a control component 320. The water pipe 210 passes through the water inlet 103 to connect the external water bottle 20 and the control component 320. The control component 320 is used to inject water into the injection receiving tank 1301 in the external water bottle 20.

[0038] Reference Figure 7 and Figure 8 When the water bottle 20 is located on one side of the water tank, the control component 320 is a water pump, which uses the water pump and water pipe 210 to inject water into the accommodating tank 1301.

[0039] This application also discloses a ventilator, including the water tank module described in the foregoing embodiments. This ventilator has the same structure and beneficial effects as the water tank module described in the foregoing embodiments.
