[0001] The present invention relates to a water tank structure of a humidifier, and more specifically, to an antibacterial cleaning water tank structure and method for a pure type humidifier. Background Art

[0002] The water tank and water tank in the humidifier are in a humid environment for a long time, which is easy to breed bacteria, and the water added to the water tank cannot be guaranteed to be free of impurities. Therefore, it is necessary to set a filter device on the water flow path inside the humidifier to filter the water to improve the cleanliness of the water, or to sterilize the water.

[0003] However, the existing humidifier filter device has a relatively complex structure, and the filter device is difficult to disassemble after installation and is not easy to replace. Summary of the invention

[0004] One of the purposes of the present invention is to solve the above-mentioned shortcomings and provide an antibacterial cleaning water tank structure and method for a pure humidifier, so as to solve the problem that the existing filter device is difficult to disassemble, replace and clean.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The present invention provides an antibacterial clean water tank structure for a pure type humidifier, comprising an outer shell and a water tank, the water tank comprising a first cavity and a second cavity, the first cavity and the second cavity being interconnected via a clean filter storage box, a primary filter screen being installed on the clean filter storage box, for allowing liquid in the first cavity to flow into the second cavity via the primary filter screen on the clean filter storage box, a water pump being installed in the outer shell, a water inlet of the water pump being connected to the second cavity, and a water outlet being connected to the first cavity.

[0007] Preferably, a further technical solution is: a water leakage hole is provided at the bottom of the first cavity, and the first cavity is connected to the cleaning filter storage box through the water leakage hole; the interior of the first cavity is used to install a drum evaporator.

[0008] A further technical solution is: a first overflow port is provided on the first cavity, and the first overflow port is communicated with the clean filter storage box.

[0009] A further technical solution is: a second overflow port is further provided on the first cavity, and the second overflow port is communicated with the second cavity.

[0010] A further technical solution is: the vertical distance from the second overflow port to the bottom of the first cavity is greater than the vertical distance from the first overflow port to the bottom of the first cavity, the opening area of ​​the second overflow port is greater than the opening area of ​​the first overflow port, and the opening area of ​​the first overflow port is greater than the opening area of ​​the leakage hole.

[0011] A further technical solution is: a mounting groove is provided above the second overflow port, and the mounting groove is located in the middle above the side wall of the first cavity.

[0012] A further technical solution is: the primary filter is located on the liquid outlet of the clean filter storage box.

[0013] A further technical solution is: a frame is installed on the inner wall of the water tank for fixing the water pump by the frame, and a slow flow platform is provided in the first cavity, and the slow flow platform is located below the connecting part between the water pump and the first cavity.

[0014] The present invention also provides an antibacterial cleaning storage method for a pure type humidifier, using an antibacterial cleaning storage structure for a pure type humidifier, comprising the following steps:

[0015] Step A, adding liquid, the liquid enters the first cavity, and flows into the clean filter storage box through the water leakage hole, and after being filtered by the primary filter screen, flows into the second cavity;

[0016] Step B, the liquid level rises. When the liquid level in the first cavity rises to the first overflow port, the liquid simultaneously flows into the clean filter storage box through the first overflow port, and after being filtered by the primary filter screen, flows into the second cavity;

[0017] Step C, stabilizing the liquid level, when the liquid level in the first cavity rises too fast and is higher than the first overflow port and continues to rise to the second overflow port, the liquid simultaneously flows directly into the second cavity through the second overflow port;

[0018] Step D, stop adding liquid. When the liquid level in the first cavity is lower than the first overflow port and no more liquid is added, the liquid continues to flow from the leaking hole through the cleaning filter storage box into the second cavity until it is drained. At this time, the first cavity remains dry.

[0019] A further technical solution is: the adding of liquid in step A is to directly add the liquid into the first cavity, or to pump the liquid in the second cavity into the first cavity by a water pump.

[0020] Compared with the prior art, the beneficial effects of the present invention are at least one of the following:

[0021] The water tank is designed to be divided into a first cavity and a second cavity, and the first cavity and the second cavity are connected through a clean filter storage box, and a primary filter is detachably installed on the clean filter storage box, so that the first cavity flows into the clean filter storage box, and flows into the second cavity after being filtered by the primary filter; thereby, impurities in the liquid are retained inside the clean filter storage box and no longer circulate between the first cavity and the second cavity, which is beneficial to improving the cleanliness of the evaporated liquid; and under the action of a water pump, the liquid in the second cavity is pumped into the first cavity, so that the liquid can be repeatedly filtered between the first cavity and the second cavity.

[0022] By designing a first overflow port connected to the clean filter storage box in the first cavity, when the liquid level in the first cavity reaches the first overflow port, the liquid can flow into the clean filter storage box through the first overflow port and the leakage hole at the same time, so that the liquid level is always maintained at the position of the first overflow port in the first cavity, which is more conducive to cooperating with the drum evaporator to improve the humidification efficiency of the humidifier and keep the humidification amount constant.

[0023] By arranging the second overflow port on the side wall of the first cavity, when the speed at which the liquid level in the first cavity rises within a unit time is greater than the sum of the amounts of liquid discharged from the leakage hole and the first overflow port, after the liquid level continues to rise to the position of the second overflow port, the liquid in the first cavity can be discharged into the second cavity simultaneously through the second overflow port, the first overflow port and the leakage hole, thereby further improving the stability of the liquid level in the first cavity and preventing the liquid from overflowing from the upper part of the first cavity due to excessively rapid rise of the liquid level in a short period of time.

DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] refer to Figure 1 , Figure 2 , Figure 3 As shown, one embodiment of the present invention is an antibacterial clean water tank structure for a pure humidifier, comprising an outer shell 1 and a water tank 2, the water tank 2 being installed in the outer shell 1, the water tank 2 comprising a first cavity 5 and a second cavity 6, the first cavity 5 and the second cavity 6 being interconnected through a clean filter receiving box 4, for the liquid in the first cavity 5 to flow into the second cavity 6 through the clean filter receiving box 4, a primary filter 12 being installed on the clean filter receiving box 4, for the liquid in the first cavity 5 to flow into the second cavity 6 through the primary filter 12 on the clean filter receiving box 4, and filtering the liquid flowing through through the primary filter 12; more importantly, in the outer shell 1 A water pump 3 is also required to be installed in the shell 1. The water inlet of the aforementioned water pump 3 is connected to the second cavity 6, and the water outlet is connected to the first cavity 5. The water pump 3 is used to pump the liquid in the second cavity 6 into the first cavity 5 through the water pump 3, so that a certain amount of liquid is maintained in the first cavity 5, so that the drum evaporator 14 placed in the first cavity 5 can be immersed below the liquid level of the first cavity 5, and the liquid below the liquid level is brought out to above the liquid level by rolling, and evaporated and humidified under the action of flowing air; and before that, the impurities in the liquid are filtered out by the aforementioned primary filter 12 and retained in the clean filter storage box 4, so as to improve the cleanliness of the evaporated liquid; at the same time, the clean filter storage box 4 can also be removed from the water tank 2 for cleaning.

[0033] refer to Figure 2 , Figure 4 As shown, in another embodiment of the present invention, it is preferred to set a leakage hole 7 at the bottom of the aforementioned first cavity 5, and the leakage hole 7 is preferably designed at the bottom of the first cavity 5, that is, the aforementioned first cavity 5 is connected with the clean filter storage box 4 through the leakage hole 7, so that the liquid in the first cavity 5 flows into the clean filter storage box 4 through the leakage hole 7, and flows into the second cavity 6 after being filtered by the primary filter screen 12 in the clean filter storage box 4.

[0034] refer to Figure 2 , Figure 3 , Figure 5As shown, in another embodiment of the present invention, since the pumping amount of the water pump can generally reach 40-60L / h, which is much larger than the drainage amount of the water leakage hole 7 and the evaporation amount of the drum evaporator 14, in order to prevent the liquid from rising too fast in the first cavity 5 and causing overflow, a first overflow port 9 can also be provided on the first cavity 5 at the same time. The first overflow port 9 is located above the clean filter storage box 4, and the first overflow port 9 is also connected to the clean filter storage box 4, so that the liquid in the first cavity 5 reaches When the liquid flows into the first overflow port 9, it flows into the cleaning filter storage box 4 through the first overflow port 9 at the same time, which can not only prevent the liquid in the first cavity 5 from overflowing, but also keep the liquid level in the first cavity 5 constant, which is conducive to cooperating with the drum evaporator 14 to maintain the stability of the evaporation and humidification amount; as shown in the figure, the bottom of the first cavity 5 is arc-shaped and is placed above the second cavity 6. The arc-shaped bottom of the first cavity 5 is convenient for matching with the second cavity 6, and it is also convenient for the liquid in the first cavity 5 to be emptied in time through the leakage hole 7 at the bottom.

[0035] Preferably, the inventors have designed the preferred structure of the drum evaporator 14 as follows: Figure 5 , Figure 6 As shown, the drum evaporator 14 includes a plurality of evaporation blades, and the plurality of evaporation blades are mounted on a rotating shaft. The evaporation blades are provided with a plurality of small through holes or blind holes, and the two ends of the rotating shaft are movably mounted in the mounting groove 11 respectively. The evaporation blades are driven to rotate by the rotating shaft, that is, during the rotation of the drum evaporator 14, the liquid in the first cavity 5 is brought out to above the liquid surface and attached to the evaporation blades of the drum evaporator 14. The liquid attached to the evaporation blades also forms a liquid film on the small through holes or blind holes through surface tension, and evaporates under the action of the flowing air, and is gasified into water vapor and mixed in the flowing air and discharged, thereby achieving air humidification.

[0036] In this embodiment, the liquid in the first cavity 5 flows into the clean filter storage box 4 through the first overflow port 9 and the leakage hole 7, flows into the second cavity 6 after being filtered by the primary filter screen 12, and the liquid in the second cavity 6 can be pumped back into the first cavity 5 by the water pump 3 for evaporation and humidification. At the same time, the liquid refluxed into the first cavity 5 can also flow into the clean filter storage box 4 through the first overflow port 9 and the leakage hole 7 again, and flow into the second cavity 6 after being filtered by the primary filter screen 12 again, so that the liquid in the water tank 2 can be circulated and filtered to improve the cleanliness of the liquid in the water tank 2.

[0037] It should be noted that the aforementioned clean filter storage box 4 is a water flow channel located between the aforementioned first cavity 5 and the aforementioned second cavity 6, which is used to connect the first cavity 5 and the second cavity 6 to each other through the clean filter storage box 4, and the aforementioned leakage hole 7 and the first overflow port 9 are respectively connected to the aforementioned clean filter storage box 4, so that the liquid in the first cavity 5 can flow into the clean filter storage box 4 through the leakage hole 7 and the first overflow port 9 respectively, and the liquid in the clean filter storage box 4 is filtered by the primary filter net 12 and then flows into the second cavity 6.

[0038] refer to Figure 2 , Figure 3 As shown, in another embodiment of the present invention, in order to avoid overflow caused by adding liquid too quickly to the first cavity 5 in a short period of time, a second overflow port 8 can be further provided on the side wall of the aforementioned first cavity 5, and the second overflow port 8 is connected with the aforementioned second cavity 6, so that when liquid is added, the liquid can also flow into the second cavity 6 through the second overflow port 8 at the same time. In this embodiment, the second overflow port 8 is directly connected with the second cavity 6 without passing through the aforementioned cleaning filter storage box 4.

[0039] Furthermore, the vertical distance from the second overflow port 8 to the bottom of the first cavity 5 is greater than the vertical distance from the first overflow port 9 to the bottom of the first cavity 5; that is, when the liquid level in the first cavity 5 rises, the liquid in the first cavity 5 first flows continuously into the clean filter storage box 4 through the leaking hole 7, and when the liquid level reaches the first overflow port 9, the liquid simultaneously flows continuously into the clean filter storage box 4 through the first overflow port 9, and if the liquid level continues to rise and reaches the second overflow port 8, the liquid then simultaneously flows continuously into the second cavity 6 through the second overflow port 8, that is, at this time, the liquid in the first cavity 5 simultaneously flows into the second cavity 6 from the second overflow port 8, the first overflow port 9 and the leaking hole 7; based on this, the opening area of ​​the second overflow port 8 needs to be greater than the opening area of ​​the first overflow port 9, and the opening area of ​​the first overflow port 9 is greater than the opening area of ​​the leaking hole 7, so that per unit time, the amount of liquid passing through the second overflow port 8 is greater than the amount of liquid passing through the first overflow port 9.

[0040] Under the above structure, when the liquid level in the first cavity 5 rises too fast, that is, when the "flood season" occurs, the liquid in the first cavity 5 flows into the second cavity 6 from the second overflow port 8, the first overflow port 9 and the leakage hole 7 at the same time; when the liquid level in the first cavity 5 rises slowly, that is, when the "dry season" occurs, the liquid in the first cavity 5 only flows into the second cavity 6 from the first overflow port 9 and the leakage hole 7 through the cleaning filter storage box 4, that is, no matter in the "flood season" or the "dry season", the liquid level in the first cavity 5 can always be kept constant, and the cycle is repeated.

[0041] As mentioned above, within a unit time, the amount of liquid pumped by the water pump 3 is greater than the sum of the amount of liquid flowing into the clean filter storage box 4 from the leaking hole 7 and the amount of liquid evaporated by the above-mentioned drum evaporator 14; wherein, the amount of liquid pumped by the above-mentioned water pump 3 is generally 40-60L / h, and the evaporation amount of the above-mentioned drum evaporator 14 is 260-410ml / h; that is, when in use, the liquid in the second cavity 6 is pumped into the first cavity 5 by the water pump 3, so that the liquid level in the first cavity 5 gradually increases, and when the liquid level in the first cavity 5 reaches the first overflow port 9, the liquid exceeding the first overflow port 9 can be discharged into the clean filter storage box 4 through the first overflow port 9.

[0042] refer to Figure 3 , Figure 5 As shown, in another embodiment of the present invention, mounting grooves 11 are arranged above the aforementioned second overflow port 8, the aforementioned mounting grooves 11 are semicircular grooves, and are located in the middle above the side wall of the aforementioned first cavity 5, and are used for the ends of the drum evaporator 14 to be respectively installed in the aforementioned mounting grooves 11. When the drum evaporator 14 is immersed below the liquid level of the first cavity 5, the drum evaporator 14 rotates to bring the liquid in the first cavity 5 out to above the liquid level, and adheres to the surface of the rolling humidifier, and completes evaporation under the action of the flowing air to achieve air humidification.

[0043] refer to Figure 1 , Figure 2 As shown, in another embodiment of the present invention, a frame 10 is installed on the inner wall of the water tank 2, which is used to fix the water pump 3 through the frame 10, and at the same time fix the pipeline connecting the water pump 3 and the first cavity 5, so as to improve the stability of the water pump 3 during operation, and to pump the liquid in the second cavity 6 into the first cavity 5 through the water pump 3, so that the liquid can achieve the above-mentioned circulation between the first cavity 5 and the second cavity 6, wherein the water pump 3 is an existing product on the market, and its specific model can be selected according to actual conditions.

[0044] refer to Figure 1 , Figure 2 As shown, in another embodiment of the present invention, a slow flow table 13 is provided in the aforementioned first cavity 5, and the aforementioned slow flow table 13 is located below the connecting portion between the aforementioned water pump 3 and the aforementioned first cavity 5, and is used to reduce the flow rate of the liquid flowing into the second cavity 6 through the slow flow table 13, and is used to reduce the sound of the liquid flowing into the first cavity 5, so as to avoid excessive noise when using the humidifier.

[0045] At the same time, in order to further kill the bacteria in the circulating liquid between the first cavity 5 and the second cavity 6, an ultraviolet sterilization lamp can be installed inside the second cavity 6 to kill the bacteria in the second cavity 6 by ultraviolet light irradiation, thereby reducing the bacteria in the circulating liquid between the first cavity 5 and the second cavity 6.

[0046] Another embodiment of the present invention is an antibacterial cleaning method based on the above water tank structure. The method needs to use the antibacterial cleaning water tank structure in the above embodiment. The method includes the following steps and is preferably performed in order:

[0047] Step S1, adding liquid, the liquid enters the first cavity, and flows into the clean filter storage box through the water leakage hole, and after being filtered by the primary filter screen, flows into the second cavity;

[0048] Step S2, the liquid level rises. When the liquid level in the first cavity rises to the first overflow port, the liquid simultaneously flows into the clean filter storage box through the first overflow port, and after being filtered by the primary filter screen, flows into the second cavity;

[0049] Step S3, stabilizing the liquid level. When the liquid level in the first cavity rises too fast and is higher than the first overflow port and continues to rise to the second overflow port, the liquid simultaneously flows directly into the second cavity through the second overflow port;

[0050] Step S4, stop adding liquid. When the liquid level in the first cavity is lower than the first overflow port and no more liquid is added, the liquid continues to flow from the leaking hole through the cleaning filter storage box into the second cavity until it is drained. At this time, the first cavity remains dry.

[0051] It should be noted that the liquid may be added in the above step S1 by directly adding the liquid into the first cavity, or by pumping the liquid in the second cavity into the first cavity through a water pump.

[0052] As mentioned in the above embodiment, in this embodiment, in order to keep the liquid level in the first cavity constant and make the rolling humidifier located in the first cavity achieve the best humidification amount, the water flow between the first cavity and the second cavity needs to be designed as follows: the liquid in the second cavity is pumped into the first cavity by the water pump, and the amount of liquid flowing out of the first overflow port per unit time is greater than the amount of liquid pumped into the first cavity by the water pump; in the same unit time, the amount of liquid pumped into the first cavity by the water pump is greater than the sum of the amount of liquid discharged from the leaking hole and the amount of liquid evaporated in the first cavity. That is, when the water pump is running, the liquid level in the first cavity can gradually rise to the position of the first overflow port, and the liquid level in the first cavity can be kept constant.
