Description

Technical Field

[0001] The utility model belongs to the technical field of humidifiers, and particularly relates to a water level anti-wave device. Background Technique

[0002] A humidifier is a device used to increase the humidity of indoor air, usually used in dry climates or seasons to improve the comfort and health of indoor air. The humidifier releases moisture into the air through methods such as steam humidification, ultrasonic humidification, and spray humidification to increase the humidity of indoor air. It can help relieve problems such as dry skin, throat discomfort, and dry eyes caused by dryness, improve indoor air quality, and promote health. It is applicable to various indoor places such as homes, offices, hospitals, and schools.

[0003] In existing humidifiers, there is no anti-wave design for the water level, and the liquid level often causes frequent start and stop of the humidifying device due to the fluctuation of the water surface, which reduces the service life of the product and frequently causes equipment failures. As a result, a large number of after-sales customer complaints occur. Due to insufficient precision, water overflow causes problems such as roof flooding and floor water ingress, leading to safety issues and endless economic disputes. Therefore, the requirements for the accuracy and safety of liquid level control in water-using equipment are getting higher and higher.

[0004] In the patent with the publication number CN113465068A, a turbine humidifier is disclosed; it increases the air discharge volume by adding a worm wheel fan, thereby improving the humidification effect and having the advantage of high humidification efficiency. However, due to the addition of the worm wheel fan, when starting, the vibration generated by the worm wheel fan is relatively large, which will cause the water surface in the water storage tank to fluctuate, making it impossible to accurately measure the water level height, resulting in frequent start and stop of the humidifier and affecting the service life of the humidifier. Content of the Utility Model

[0005] The purpose of the utility model is to provide a water level anti-wave device to solve the following technical problems raised in the background technique:

[0006] The existing water storage tank of the humidifier has no anti-wave design, and the water surface fluctuation will affect the measurement of the water level.

[0007] To solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A water level anti-wave device is arranged in the middle of the water storage container. The anti-wave device includes a liquid level installation shell, a liquid level cover plate, and a capacitance liquid level gauge;

[0009] The liquid level cover plate is arranged above the liquid level installation shell, and the capacitance liquid level gauge is arranged below the liquid level cover plate and inside the liquid level installation shell; through holes are arranged on both sides of the liquid level installation shell; anti-wave grid parts are arranged in the through holes;

[0010] The wave - proof grid member includes an outer fence and an inner fence; the outer fence is of a U - shaped structure and is evenly spaced within the passing opening. A U - shaped first passing gap is formed between the outer fence and the liquid - level installation shell or adjacent outer fences; the inner fence is arranged inside the outer fence, the inner fence is of a U - shaped structure and is evenly spaced within the passing opening. Each inner fence is aligned with the adjacent first passing gap, and a U - shaped second passing gap is formed between the inner fence and the liquid - level installation shell or adjacent inner fences.

[0011] Furthermore, the liquid - level cover plate is hermetically connected to the liquid - level installation shell.

[0012] Furthermore, a connecting rod is fixedly connected to the bottom of the outer fence, and the inner fence is fixedly connected to the connecting rod.

[0013] Furthermore, a liquid - level gauge wire harness is provided on the capacitance liquid - level gauge. Two liquid - level gauge wire harness pressing plates, one long and one short, are fixedly connected to the bottom of the liquid - level cover plate. The liquid - level gauge wire harness pressing plates are used to fix the liquid - level gauge wire harness located at the bottom of the liquid - level cover plate into a continuous U - shaped structure.

[0014] Furthermore, a liquid - level pressing plate is fixedly connected to the bottom of the liquid - level cover plate, and the liquid - level pressing plate is connected to the capacitance liquid - level gauge.

[0015] Furthermore, a diversion hole is provided in the middle of the liquid - level cover plate.

[0016] Furthermore, liquid - level isolation cabins are provided on both sides inside the liquid - level installation shell, and the capacitance liquid - level gauge is arranged in the liquid - level isolation cabin.

[0017] Furthermore, two capacitance liquid - level gauges are provided, and the position of one capacitance liquid - level gauge is higher than that of the other.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The utility model is provided with a wave - proof device. The wave - proof device uses the wave - proof grid member to prevent waves. The wave - proof grid member includes an outer fence and an inner fence. Since both the outer fence and the inner fence are of U - shaped structures, the first passing gap and the second passing gap formed by the inner fence and the outer fence are also of U - shaped structures. The inner fence is clamped between the outer fences. When water flows through here, it needs to first pass through the first passing gap, enter between the outer fence and the inner fence, then pass through the second passing gap to enter the interior of the inner fence, then pass through the second passing gap to exit from the inner fence and enter between the inner fence and the outer fence, and finally flow into the liquid - level installation shell through the first passing gap. During this process, the ripples generated by water fluctuations are almost completely blocked by the outer fence and the inner fence, so that the water entering the interior of the liquid - level installation shell is very stable.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0028] Embodiment

[0029] A water level anti-wave device, as Figure 3 shown, is arranged in the middle of the water storage container 7. The anti-wave device 8 includes a liquid level mounting shell 1, a liquid level cover plate 2 and a capacitive liquid level gauge 3;

[0030] As Figures 2 to 3 shown, the liquid level cover plate 2 is arranged above the liquid level mounting shell 1, and the capacitive liquid level gauge 3 is arranged below the liquid level cover plate 2 and inside the liquid level mounting shell 1; through openings are arranged on both sides of the liquid level mounting shell 1; anti-wave grid members are arranged in the through openings; wherein, the capacitive liquid level gauge 3 is used to measure the liquid level height of the water storage container 7.

[0031] As Figures 4 to 6As shown, the wave-proof grid member includes an outer fence 9 and an inner fence 12; the outer fence 9 is of a U-shaped structure and is evenly spaced within the through-port. A U-shaped first through-gap 11 is formed between the outer fence 9 and the liquid-level mounting shell 1 or adjacent outer fences 9; the inner fence 12 is arranged inside the outer fence 9, the inner fence 12 is of a U-shaped structure and is evenly spaced within the through-port. Each inner fence 12 is aligned with the adjacent first through-gap 11, and a U-shaped second through-gap 13 is formed between the inner fence 12 and the liquid-level mounting shell 1 or adjacent inner fences 12.

[0032] During use, as Figure 3 shown, the water in the water storage container 7 fluctuates, causing ripples in the water storage container 7. The space in the middle separated by the wave-proof device 8 is relatively small, and the water in the wave-proof device 8 fluctuates less. When the ripples on both sides of the water storage device move towards the middle, they will first pass through the first through-gap 11 between the outer fences 9 and interfere with the inner fences 12. Specifically, as Figure 3 shown, since the outer fence 9 only allows a small amount of water to pass through the first through-gap 11, most of the water will impact the liquid-level mounting shell 1 or the outer fence 9, and part of the energy in the water is consumed. Subsequently, the water enters between the outer fence 9 and the inner fence 12, and then flows out from the first through-gap 11 inside the outer fence 9 after passing through the two layers of second through-gaps 13 and enters the inside of the liquid-level mounting shell 1. It should be noted here that since both the outer fence 9 and the inner fence 12 are of U-shaped structures, the first through-gap 11 and the second through-gap 13 formed by the inner fence 12 and the outer fence 9 are also of U-shaped structures. The inner fence 12 is sandwiched between the outer fences 9. When the water flow passes through here, it needs to first pass through the first through-gap 11, enter between the outer fence 9 and the inner fence 12, then pass through the second through-gap 13 into the inside of the inner fence 12, then pass through the second through-gap 13 and exit from the inner fence 12 and enter between the inner fence 12 and the outer fence 9, and finally flow into the liquid-level mounting shell 1 through the first through-gap 11. During this process, the ripples generated by the water fluctuation are almost completely blocked by the outer fence 9 and the inner fence 12, so that the water entering the inside of the liquid-level mounting shell 1 is very stable. Thus, the stability of the detected water in the wave-proof device 8 is ensured. Finally, the water level is measured by the capacitance liquid-level gauge 3 to obtain a relatively accurate liquid-level condition, thereby ensuring the normal operation and rotation of the humidifier.

[0033] In a preferred embodiment, the liquid-level cover plate 2 is hermetically connected to the liquid-level mounting shell 1. Since electronic devices are provided inside the liquid-level cover plate 2, it is necessary to ensure the sealing between the two to prevent the water in the liquid-level mounting shell 1 from entering the inside of the liquid-level cover plate 2.

[0034] In a preferred embodiment, as Figures 4 to 5As shown, a connecting rod 10 is fixedly connected to the bottom of the outer fence 9, and the inner fence 12 is fixedly connected to the connecting rod 10. The connection at the bottom of the outer fence 9 can connect all the outer fences 9 in series, making all the outer fences 9 into a whole, which can enhance the structural strength of the outer fence 9. At the same time, the design of the connecting rod can also facilitate the installation of the inner fence 12, and the inner fence 12 can be directly installed on the connecting rod 10. The inner fence 12 installed on the connecting rod 10 can easily align with the first passing gap 11 and can ensure effective structural strength.

[0035] In a preferred embodiment, as Figure 2 shown, a level gauge wire harness 4 is provided on the capacitance level gauge 3. Two level gauge wire harness 4 pressing plates, one long and one short, are fixedly connected to the bottom of the level cover plate 2. The level gauge wire harness 4 pressing plates are used to fix the level gauge wire harness 4 located at the bottom of the level cover plate 2 into a continuous U-shaped structure. During use, water droplets in the wave-proof device 8 are likely to splash into the level gauge wire harness 4. Therefore, bending the level gauge wire harness 4 into a continuous U-shaped structure by the level gauge wire harness 4 pressing plates can effectively prevent water from flowing along the level gauge wire harness 4.

[0036] In a preferred embodiment, as Figure 2 shown, a level pressing plate 6 is fixedly connected to the bottom of the level cover plate 2, and the level pressing plate 6 is connected to the capacitance level gauge 3. The level pressing plate 6 is used to conveniently fix the position of the capacitance level gauge 3.

[0037] In a preferred embodiment, a diversion hole is provided in the middle of the level cover plate 2. The diversion hole in the middle of the level cover plate 2 enables the water splashed on the level cover plate 2 to flow into the level installation shell 1.

[0038] In a preferred embodiment, level isolation compartments are provided on both sides inside the level installation shell 1, and the capacitance level gauge 3 is arranged in the level isolation compartments. The level isolation compartments are used to protect the capacitance level gauge 3 because the capacitance level gauge 3 needs waterproof protection during use.

[0039] In a preferred embodiment, two capacitance level gauges 3 are provided, and the position of one capacitance level gauge 3 is higher than that of the other. The one with a higher position serves as the capacitance level gauge 3 for high-level measurement, and the one with a lower position serves as the low-level capacitance level gauge 3, so as to facilitate the accurate measurement of the liquid level height inside the level installation shell 1.
