Abstract
Description
Technical Field
[0001] This utility model relates to the field of water purification equipment technology, and in particular to a water tank and a water purification device containing the same. Background Technology
[0002] Currently, water purification products filter impurities from tap water using filter cartridges to obtain purified water. Limited by booster pumps and filter membranes, the water flow rate is generally not very high. Most mainstream water purification equipment currently has a flow rate of less than 2L / min. To provide users with a better water experience, there is a type of volumetric high-flow-rate water purification product. This product has a built-in water tank, and the purified water is stored in the tank before being pumped out using a high-flow-rate pump to achieve a large-flow-rate output.
[0003] This type of high-flow-rate product can provide a large flow of water, but it also has the problem of bacterial growth in the water tank. To solve this problem, a static UV sterilization lamp is usually installed inside the water tank. The UV sterilization lamp kills bacteria in the water tank or inhibits their growth.
[0004] Generally, water tanks have irregular structures, while the effective irradiation range of a germicidal lamp is conical. Therefore, there are areas in the water tank that cannot be irradiated. In this case, products achieve sterilization and bacteriostasis effects through prolonged irradiation, such as continuous irradiation for more than 1 hour. However, prolonged irradiation not only affects the lifespan of the sterilization device but also accelerates the aging of the water tank itself. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a water tank and a water purification device containing the same.
[0006] The present invention solves the above-mentioned technical problems through the following technical solution:
[0007] A water tank includes a tank body and a germicidal lamp. The germicidal lamp is installed in the tank body, and the optical axis of the germicidal lamp is oriented toward the water storage cavity of the tank body. The water tank also includes a driving device. The germicidal lamp is flexibly connected to the tank body. The rotation shaft of the driving device abuts against the germicidal lamp, and the rotation shaft is angularly arranged with respect to the optical axis of the germicidal lamp. The driving device is used to drive the germicidal lamp to deflect via the rotation shaft, thereby changing the orientation of the optical axis.
[0008] In this technical solution, the sterilizing lamp is flexibly connected to the housing, and the rotating shaft of the drive device abuts against the sterilizing lamp. The rotating shaft is set at an angle to the optical axis of the sterilizing lamp, so that the sterilizing lamp is driven to deflect by the rotating shaft of the drive device, thereby changing the orientation of the optical axis of the sterilizing lamp in the housing. By changing the way the sterilizing lamp irradiates in the housing, the light projected by the sterilizing lamp can irradiate different areas of the water storage chamber, thus solving the contradiction between the sterilization effect and the irradiation time and effectively avoiding the accelerated aging of the water tank body.
[0009] Preferably, the water tank includes a rotor, and along the axial direction of the rotor, the rotor has a first surface and a second surface disposed opposite to each other, the rotation shaft is perpendicularly connected to the first surface, the first surface and the second surface are not parallel, and the germicidal lamp abuts against the second surface.
[0010] In this technical solution, a specific installation scheme is provided in which the rotating shaft and the optical shaft are set at an angle. By setting a wheel with a first surface and a second surface that are set opposite to each other and are not parallel, the rotating shaft is connected to the first surface and the germicidal lamp abuts against the second surface, which makes it easier to fix the germicidal lamp.
[0011] Preferably, the rotating wheel is coaxial with the rotating shaft.
[0012] In this technical solution, by setting the rotating wheel and the rotating shaft coaxially, the outer peripheral position of the rotating wheel remains unchanged when the rotating shaft drives the rotating wheel to rotate, making it easier to fix the rotating wheel.
[0013] Preferably, the housing is provided with through mounting holes, and the drive device, the rotating wheel and the germicidal lamp are installed in the mounting holes from the outside to the inside, with the power cords of the drive device and the germicidal lamp extending out from the mounting holes;
[0014] The water tank also includes a sealing element made of a flexible material. The outer periphery of the sealing element is fixed to the outer periphery of the mounting hole. The sealing element has a through hole through which the germicidal lamp passes.
[0015] In this technical solution, compared to installing the drive unit, rotor, and germicidal lamp inside the water storage chamber and then leading out the power cords of the drive unit and germicidal lamp through small holes, installing the drive unit, rotor, and germicidal lamp using mounting holes reduces the space occupied inside the water storage chamber, allowing the water tank to store a larger volume of water. Simultaneously, the inclusion of sealing components improves the water tank's sealing performance, preventing leaks.
[0016] Preferably, the germicidal lamp has a groove extending circumferentially along the optical axis of the germicidal lamp, and the sealing member located on the periphery of the through hole is embedded in the groove.
[0017] In this technical solution, by setting a groove on the germicidal lamp and embedding the sealing element in the groove, the sealing effect can be further improved;
[0018] Preferably, the inner surface of the germicidal lamp is flush with the inner surface of the housing.
[0019] In this technical solution, by setting the inner surface of the germicidal lamp to be flush with the inner surface of the box, the germicidal lamp does not extend into the water storage cavity, which can further avoid the germicidal lamp occupying the space of the water storage tank.
[0020] Preferably, the seal covers the outer side of the housing, the outer surface of the housing has a protrusion facing the seal, the inner surface of the seal has a groove facing the housing, and the protrusion is embedded in the groove.
[0021] Preferably, the water tank further includes a pressure cap, which is disposed on the outside of the seal. The pressure cap and the tank body are fixed together by a groove and a boss. The pressure cap and the seal are fixed together by a groove and a boss. The pressure cap has a clearance hole that extends through the inside and outside. The drive device and the wheel are disposed in the clearance hole, and the drive device is connected to the pressure cap.
[0022] Preferably, the angle between the rotation axis and the optical axis is α, and the value of α is in the range of α ≥ 5°.
[0023] In this technical solution, by setting the angle between the rotating shaft and the second surface to be greater than or equal to 5°, the area that the germicidal lamp can illuminate is larger, thereby improving the sterilization effect.
[0024] Preferably, the angle between the rotation axis and the optical axis is α, and the value of α is in the range of α ≤ 45°.
[0025] In this technical solution, by setting the angle between the rotating shaft and the optical axis to less than or equal to 45°, the excessive movement range of the germicidal lamp during deflection is avoided, which could cause the seal to slip out of the groove.
[0026] Preferably, the driving device is a motor.
[0027] A water purification device, the water purification device comprising the water tank as described above.
[0028] The positive and progressive effects of this utility model are as follows: by setting a driving device to connect to the sterilizing lamp, the rotating shaft of the driving device is connected to the sterilizing lamp, and the rotating shaft is set at an angle to the optical axis of the sterilizing lamp, so that the sterilizing lamp is driven to deflect by the rotating shaft of the driving device, thereby changing the orientation of the optical axis of the sterilizing lamp in the tank. By changing the way the sterilizing lamp irradiates in the tank, the light projected by the sterilizing lamp can irradiate different areas of the water storage chamber, thus solving the contradiction between the sterilization effect and the irradiation time, and effectively avoiding the accelerated aging of the water tank body.

[0046] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0047] like Figures 1-3As shown, this embodiment provides a water purification device, which includes a water tank 100 for storing purified water. The water tank 100 includes a tank body 1 and a sterilizing lamp 4. The sterilizing lamp 4 is installed in the tank body 1, and the optical axis of the sterilizing lamp 4 is set towards the water storage cavity 101 of the tank body 1. The water tank 100 also includes a driving device 2. The sterilizing lamp 4 is flexibly connected to the tank body 1. The rotating shaft 21 of the driving device 2 abuts against the sterilizing lamp 4, and the rotating shaft 21 is set at an angle to the optical axis L of the sterilizing lamp 4. The driving device is used to drive the sterilizing lamp to deflect through the rotating shaft to change the orientation of the optical axis. By flexibly connecting the sterilizing lamp 4 to the housing 1, the rotating shaft 21 of the drive device 2 abuts against the sterilizing lamp 4, and the rotating shaft 21 is set at an angle to the optical axis L of the sterilizing lamp 4, so that the sterilizing lamp 4 is driven to deflect by the rotating shaft 21 of the drive device 2, changing the orientation of the optical axis L of the sterilizing lamp 4 in the housing 1. By changing the irradiation position of the sterilizing lamp 4 in the housing 1, the light projected by the sterilizing lamp 4 can irradiate different areas of the water storage chamber 101, solving the contradiction between the sterilization effect and the irradiation time, and effectively avoiding the accelerated aging of the water tank body.
[0048] Specifically, in this embodiment, the water tank includes a rotating wheel 3. Along the axial direction of the rotating wheel 3, the rotating wheel 3 has a first surface 301 and a second surface 302 that are arranged opposite to each other. A rotating shaft 21 is perpendicularly connected to the first surface 301. The first surface 301 and the second surface 302 are not parallel, and the germicidal lamp 4 abuts against the second surface 302. By setting the rotating wheel 3 with the first surface 301 and the second surface 302 that are arranged opposite to each other and not parallel, and the rotating shaft 21 being perpendicularly connected to the first surface 301, and the germicidal lamp 4 abutting against the second surface 302, it is easier to fix the germicidal lamp 4.
[0049] in, Figure 2 and Figure 3 The germicidal lamp 4 shown is for illustrative purposes only. In actual applications, the germicidal lamp 4 is tilted, and there is an angle between the optical axis and the rotation axis of the germicidal lamp 4.
[0050] Meanwhile, the angle between the rotating shaft 21 and the optical axis L is α, and the preferred value of α is 5° ≤ α ≤ 45°. By setting the angle between the rotating shaft and the optical axis L to be greater than or equal to 5°, the area that the light from the germicidal lamp 4 can illuminate is larger, thus improving the sterilization effect. By setting the angle between the rotating shaft and the optical axis L to be less than or equal to 45°, excessive movement of the germicidal lamp 4 during deflection is avoided, which could cause the seal 5 to slip out of the groove.
[0051] Specifically, in this embodiment, a = 5°.
[0052] Of course, in other embodiments, the germicidal lamp 4 and the rotating shaft 21 can be directly abutted together. Meanwhile, 'a' can be set to other suitable angles according to the projection shape and range of the germicidal beam, etc., which will not be elaborated here.
[0053] Specifically, in this embodiment, the rotating wheel 3 is coaxially arranged with the rotating shaft. That is, the axis of the rotating wheel 3 coincides with the axis of the rotating shaft 21. By coaxially arranging the rotating wheel 3 with the rotating shaft 21, the outer peripheral position of the rotating wheel 3 remains unchanged when the rotating shaft 21 drives the rotating wheel 3 to rotate. This makes it easier to fix the rotating wheel 3 and also makes the structure of the water tank more compact.
[0054] Of course, in other embodiments, the axis of the rotating wheel 3 may not coincide with the rotating shaft 21. When the driving device 2 drives the rotating wheel 3 to rotate, the rotating wheel 3 rotates eccentrically. The germicidal lamp 4 fixed on the rotating wheel 3 moves under the drive of the rotating wheel 3. The projection range of the germicidal lamp 4 is larger, but the eccentric rotating wheel 3 requires a larger installation space and the structural compactness decreases.
[0055] In this embodiment, the housing 1 has through-holes. The drive unit, the rotating wheel 3, and the germicidal lamp 4 are installed sequentially from the outside to the inside of the mounting holes. The power cords of the drive unit and the germicidal lamp 4 extend from the mounting holes. The water tank also includes a sealing element 5, which is made of a flexible material. The outer periphery of the sealing element 5 is fixed to the outer periphery of the mounting hole. The sealing element 5 has a through hole through which the germicidal lamp 4 passes, thereby achieving a flexible connection between the germicidal lamp 4 and the housing 1. The sealing element 5 provides upward support for the germicidal lamp 4. When the second surface 302 of the rotating wheel 3 abuts against the germicidal lamp 4, it exerts downward pressure on the germicidal lamp 4. Therefore, when the germicidal lamp 4 abuts against the rotating wheel 3, the lowest point of the second surface 302 moves downward at the point of contact with the germicidal lamp 4, while the side of the germicidal lamp 4 closest to the highest point of the second surface 302 moves upward under the support of the sealing element 5, thus causing the germicidal lamp 4 to be in an inclined state. When the rotor 3 rotates, due to the inclined arrangement of the second surface 302, the lowest point of the second surface 302 will abut against different positions of the germicidal lamp 4 during the rotation of the rotor 3. Furthermore, the position where the germicidal lamp 4 abuts against the second surface 302 is tilted downwards, resulting in different deflection directions of the germicidal lamp 4. Compared to installing the drive unit, rotor 3, and germicidal lamp 4 inside the water storage chamber 101 and then leading out the power cords of the drive unit and germicidal lamp 4 through small holes, installing the drive unit, rotor 3, and germicidal lamp 4 through mounting holes reduces the space occupied inside the water storage chamber 101, allowing the water tank to store a larger amount of water. Simultaneously, the sealing element 5 improves the water tank's sealing performance, preventing leakage.
[0056] Of course, in other embodiments, the drive device, the rotating wheel 3 and the germicidal lamp 4 can also be installed in the water storage chamber 101 and the power cords of the drive device and the germicidal lamp 4 can be led out through the small hole, which will not be described in detail here.
[0057] Specifically, in this embodiment, the germicidal lamp 4 has a threaded part on the side near the water storage chamber. The diameter of the threaded part is smaller than the diameter of other parts of the germicidal lamp 4. The threaded part passes through the through hole of the sealing member 5. At the same time, the germicidal lamp is provided with a nut that matches the threaded part. The sealing member 5 is pressed by the cooperation between the nut and the threaded part, thereby realizing the sealed connection between the box 1 and the germicidal lamp 4 and preventing water leakage.
[0058] Of course, in other embodiments, a groove extending circumferentially along the optical axis L of the germicidal lamp 4 can also be provided on the germicidal lamp 4, and the sealing member 5 located on the periphery of the through hole can be embedded in the groove to improve the sealing effect of the water tank. Optionally, the connection strength and sealing effect between the germicidal lamp 4 and the sealing member 5 can be further improved by applying sealant or the like.
[0059] Meanwhile, in this embodiment, the inner surface of the germicidal lamp 4 is flush with the inner surface of the housing 1. By setting the inner surface of the germicidal lamp 4 to be flush with the inner surface of the housing 1, the germicidal lamp 4 does not extend into the water storage chamber 101, which further avoids the germicidal lamp 4 occupying the space of the water storage tank.
[0060] In this embodiment, the sealing member 5 covers the outside of the box body 1, the outer surface of the box body 1 has a protrusion facing the sealing member 5, the inner surface of the sealing member 5 has a groove facing the box body 1, and the protrusion is embedded in the groove.
[0061] Meanwhile, the water tank also includes a pressure cap 6, which is made of rigid material. The pressure cap 6 is located on the outside of the sealing element 5 and is fixed to the tank body 1 by grooves and bosses. The pressure cap 6 has through-holes that allow for internal and external clearance. The drive device and the rotating wheel 3 are located in the clearance holes, and the drive device is connected to the pressure cap 6. The pressure cap 6 also has a connecting part 61, which is connected to the tank body 1 by screws to achieve reliable fixation of the pressure cap 6.
[0062] Specifically, in this embodiment, the driving device is a motor.
[0063] Of course, in other embodiments, the driving device 2 can also be other devices in the prior art that can drive the germicidal lamp 4 to rotate, which will not be described in detail here.
[0064] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
