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 being used to sterilize water in the water storage chamber of the tank body, the water tank further comprising:
[0008] A fixed shaft is connected to the top wall of the water storage cavity and extends vertically.
[0009] Float;
[0010] A rotating component is installed at the lower end of the fixed shaft. The float and the germicidal lamp are both connected to the rotating component. The float can cause the rotating component to swing relative to the axis of the fixed shaft when the water level in the water storage chamber changes, so that the optical axis of the germicidal lamp swings.
[0011] In this technical solution, a float and a rotating component are installed in the water tank. Both the float and the germicidal lamp are connected to the rotating component. When the water level in the storage chamber changes, the float rises or falls under the action of buoyancy, thereby causing the axis of the rotating component to swing relative to the fixed axis. This causes the germicidal lamp connected to the rotating component to swing as well, thereby changing the orientation of the optical axis of the germicidal lamp. This allows the germicidal lamp to irradiate different positions in the storage chamber, improving the sterilization effect of the germicidal lamp and preventing the tank from aging due to the germicidal lamp continuously irradiating a certain position of the water tank for a long time.
[0012] Preferably, the rotating member is hinged to the fixed shaft.
[0013] Preferably, the rotating member is ball-jointed with the fixed shaft.
[0014] Preferably, the rotating component is provided with a through hole, the fixed shaft passes through the through hole, and there is a gap between the fixed shaft and the peripheral wall of the through hole. The water tank also includes a first limiting structure, which is disposed below the through hole and is used to restrict the fixed shaft from disengaging from the through hole.
[0015] In this technical solution, by providing a through hole in the rotating component and inserting the fixed shaft through the through hole, the connection between the rotating component and the fixed shaft can be made more reliable. At the same time, by providing a gap between the fixed shaft and the peripheral wall of the through hole, the rotating component can swing, preventing the fixed shaft and the through hole from jamming.
[0016] Preferably, the fixed shaft has a connecting portion that passes through the through hole. The connecting portion has a cylindrical structure, and the radial dimension of the through hole is larger than the diameter of the connecting portion.
[0017] In this technical solution, by setting the connecting part as a cylindrical structure, when the water level in the water storage chamber changes, the float ball can not only drive the rotating part to swing, but also make the rotating part rotate more smoothly around the axis of the fixed shaft. The optical axis of the germicidal lamp faces a wider angle, allowing the germicidal lamp to irradiate more positions in the water storage chamber, further improving the sterilization effect of the germicidal lamp.
[0018] Preferably, the through hole is a cylindrical through hole.
[0019] Preferably, the water tank further includes a second limiting structure, which is disposed above the through hole and is used to restrict the upward movement of the rotating member.
[0020] Preferably, the first limiting structure is arranged circumferentially around the through hole.
[0021] Preferably, the second limiting structure is arranged circumferentially around the through hole.
[0022] Preferably, a limiting step is formed on the fixed shaft, the limiting step is located at the top of the connecting part, and the second limiting structure is the limiting step.
[0023] In this technical solution, by setting a dimensional difference on the fixed shaft, that is, setting the diameter of the connecting part to be slightly smaller than the diameter of the fixed shaft above the connecting part, a limiting step that can serve as a second limiting structure can be formed on the fixed shaft, making the structure of the second limiting structure simpler and more reliable, without the need to add additional parts as the second limiting structure.
[0024] Preferably, a first recess is formed on the lower surface of the rotating member, and a second recess is formed on the upper surface of the rotating member;
[0025] When the rotating member deflects relative to the axis of the fixed shaft, the first recess provides clearance space for the first limiting structure, and the second recess provides clearance space for the second limiting structure.
[0026] Preferably, the rotating component includes a first rod and a second rod in an L-shape, the float and the fixed shaft are respectively connected to the two ends of the first rod, one end of the second rod is vertically connected to the middle of the first rod, and the germicidal lamp is connected to the other end of the second rod and to the side away from the float.
[0027] In this technical solution, by setting the rotating component as a first rod and a second rod, with the second rod vertically connected to the first rod, the float and the fixed shaft both connected to the first rod, and the germicidal lamp connected to the second rod on the side away from the float, interference between the germicidal lamp and the fixed shaft and the float is avoided.
[0028] A water purification device, the water purification device comprising the water tank as described above.
[0029] The positive and progressive effects of this utility model are as follows: By setting a float and a rotating component in the water tank, both the float and the germicidal lamp are connected to the rotating component. When the water level in the water storage chamber changes, the float rises or falls under the action of buoyancy, thereby causing the axis of the rotating component to swing relative to the fixed axis. This causes the germicidal lamp connected to the rotating component to swing as well, thereby changing the orientation of the optical axis of the germicidal lamp. This allows the germicidal lamp to irradiate different positions in the water storage chamber, improving the sterilization effect of the germicidal lamp, and avoiding the aging of the tank body caused by the germicidal lamp continuously irradiating a certain position of the water tank for a long time.

[0052] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0053] like Figures 1-6As shown, this embodiment provides a water tank 100, which includes a tank body 1 and a germicidal lamp 2. The germicidal lamp 2 is used to sterilize the water in the water storage chamber of the tank body 1. The water tank 100 also includes a fixed shaft 3, a float 4, and a rotating component 5. The fixed shaft 3 is connected to the top wall of the water storage chamber and extends vertically. The rotating component 5 is installed at the lower end of the fixed shaft 3. The float 4 and the germicidal lamp 2 are both connected to the rotating component 5. The float 4 can drive the rotating component 5 to deflect relative to the axis of the fixed shaft 3 when the water level in the water storage chamber changes, so that the optical axis L of the germicidal lamp 2 swings. By setting a float ball 4 and a rotating component 5 in the water tank 100, both the float ball 4 and the sterilizing lamp 2 are connected to the rotating component 5. When the water level in the water storage chamber changes, the float ball 4 rises or falls under the action of buoyancy, thereby causing the rotating component 5 to swing relative to the axis of the fixed shaft 3. This causes the sterilizing lamp 2 connected to the rotating component 5 to swing as well, thereby changing the orientation of the optical axis L of the sterilizing lamp 2. This allows the sterilizing lamp 2 to irradiate different positions in the water storage chamber, improving the sterilization effect of the sterilizing lamp 2 and preventing the sterilizing lamp 2 from continuously irradiating a certain position in the water tank 100 for a long time, which would cause the tank body 1 to age.
[0054] like Figure 1 and Figure 2 As shown, Figure 1 The middle section is a cross-sectional structural diagram of the water tank when the water storage chamber is full of water. Figure 2 This is a cross-sectional structural diagram of the water tank when the water storage chamber is not full. In this embodiment, the axial deviation of the rotating component 5 relative to the fixed shaft 3 refers to the change in the angle between the axis of the rotating component 5 and the axis of the fixed shaft 3 under the action of the float 4, thereby causing a change in the orientation of the optical axis L of the germicidal lamp 2 fixed on the rotating component 5.
[0055] Specifically in this embodiment, such as Figures 1-4 As shown, the rotating component 5 has a through hole 501, and the fixed shaft 3 passes through the through hole 501. There is a gap between the fixed shaft 3 and the peripheral wall of the through hole 501. The water tank 100 also includes a first limiting structure 6, which is located below the through hole 501 and is used to prevent the fixed shaft 3 from disengaging from the through hole 501. By providing a through hole 501 on the rotating component 5 and passing the fixed shaft 3 through the through hole 501, the connection between the rotating component 5 and the fixed shaft 3 is made more reliable. At the same time, the gap between the fixed shaft 3 and the peripheral wall of the through hole 501 allows the rotating component 5 to sway, preventing the fixed shaft 3 from getting stuck between the through hole 501 and the fixed shaft 3.
[0056] Of course, in other embodiments, the rotating member 5 and the fixed shaft 3 can be connected by a hinge or a ball joint, so as to achieve the purpose of the rotating member 5 deflecting relative to the axis of the fixed shaft 3 under the drive of the float 4.
[0057] In this embodiment, as Figure 5 and Figure 6 As shown, the fixed shaft 3 has a connecting part 31, such as Figure 1 and Figure 2 As shown, the connecting part 31 passes through the through hole 501. The connecting part 31 has a cylindrical structure, and the through hole 501 is a cylindrical through hole with a diameter larger than that of the connecting part 31. By setting the connecting part 31 to a cylindrical structure, when the water level in the water storage chamber changes, the float 4 can not only drive the rotating part 5 to swing, but also make the rotating part 5 rotate more smoothly around the axis of the fixed shaft 3. The optical axis L of the germicidal lamp 2 faces a wider angle, allowing the germicidal lamp 2 to irradiate more areas in the water storage chamber, further improving the sterilization effect of the germicidal lamp 2.
[0058] Of course, in other embodiments, the connecting part 31 may also be a non-cylindrical structure, and the through hole 501 may also be a non-cylindrical through hole. In this case, the rotating part 5 may not be able to rotate around the axis of the fixed shaft 3 or the smoothness of rotation may decrease. However, the rotating part 5 can still swing. The irradiation range of the germicidal lamp 2 fixed on the swingable rotating part 5 is still larger than the irradiation range when the germicidal lamp 2 is directly fixed to the box 1, which can improve the sterilization effect of the germicidal lamp 2.
[0059] In this embodiment, the water tank 100 also includes a second limiting structure, which is disposed above the through hole 501 and is used to restrict the upward movement of the rotating member 5.
[0060] Specifically, in this embodiment, both the first limiting structure 6 and the second limiting structure are arranged circumferentially around the through hole 501. That is, when the rotating member 5 rotates around the axis of the fixed shaft 3 along the circumferential direction of the fixed shaft 3, the rotating member 5 will be limited between the first limiting structure 6 and the second limiting structure at any position.
[0061] Specifically, the first limiting structure 6 is a cylindrical sleeve connected to the bottom of the connecting part 31. A limiting step 32 is formed on the fixed shaft 3, located at the top of the connecting part 31, and the second limiting structure is the limiting step 32. By setting a dimensional difference on the fixed shaft 3, that is, setting the diameter of the connecting part 31 to be slightly smaller than the diameter of the fixed shaft 3 above the connecting part 31, a limiting step 32 that can serve as the second limiting structure can be formed on the fixed shaft 3. This makes the structure of the second limiting structure simpler and more reliable, without the need for additional parts as the second limiting structure.
[0062] Of course, in other embodiments, the first limiting structure 6 may also be a protrusion on the top of the connecting part 31, or a plurality of protrusions spaced circumferentially along the bottom of the connecting part 31. Similarly, the second limiting structure may also be a protrusion on the fixed shaft 3 above the connecting part 31, or a plurality of protrusions spaced circumferentially along the fixed shaft 3 above the connecting part 31. Further details will not be provided here.
[0063] In this embodiment, as Figure 3 and Figure 4 As shown, the rotating component 5 includes a first rod 51 and a second rod 52 with an L-shaped structure. A float 4 and a fixed shaft 3 are respectively connected to both ends of the first rod 51. That is, a through hole 501 is provided on the first rod 51. The second rod 52 is vertically connected to the lower surface of the first rod 51, and the connection point between the second rod 52 and the first rod 51 is located in the middle of the first rod 51. The germicidal lamp 2 is connected to the side of the second rod 52 away from the float 4. By setting the rotating component 5 as a first rod 51 and a second rod 52, with the second rod 52 vertically connected to the lower surface of the first rod 51, the fixed shaft 3 above the rotating component 5, and both the float 4 and the fixed shaft 3 connected to the first rod 51, and the germicidal lamp 2 connected to the side of the second rod 52 away from the float 4, interference between the germicidal lamp 2 and the fixed shaft 3 is avoided in the vertical direction, and interference between the germicidal lamp 2 and the float 4 is avoided in the horizontal direction.
[0064] Specifically, the L-shaped structure of the second rod 52 of the adapter is configured such that after the second rod 52 extends a distance perpendicular to the first rod 51 to ensure that the germicidal lamp 2 will not interfere with the fixed shaft 3, it bends away from the float 4. The germicidal lamp 2 is fixed at the position after the second rod 52 is bent, so that the germicidal lamp 2 and the float 4 are as far apart as possible, thereby ensuring that the germicidal lamp 2 does not interfere with the fixed shaft 3 and the float 4.
[0065] In this embodiment, as Figure 1 As shown, the germicidal lamp 2 is configured such that when the water storage chamber is full of water, the float 4 drives the rotating component 5 to swing to its highest position. At this time, the optical axis L of the germicidal lamp 2 is vertical, meaning the front of the germicidal lamp 2 is facing downwards. Specifically, the upper surface of the first limiting structure 6 and the lower surface of the second limiting structure are both horizontally positioned, and the distance between the upper surface of the first limiting structure 6 and the lower surface of the second limiting structure is equal to the thickness of the first rod 51. When the water storage chamber is full of water, the float 4 drives the rotating component 5 to rise until the first rod 51 is horizontal. The upper surface of the first limiting structure 6 abuts against the lower surface of the first rod 51, and the lower surface of the second limiting structure abuts against the upper surface of the first rod 51. The first rod 51 remains horizontal, and the float 4 cannot rise further.
[0066] At the same time, such as Figures 1-4As shown, a first recess 502 is formed on the lower surface of the rotating member 5. The first recess 502 extends from the side of the peripheral wall of the through hole 501 away from the float 4 towards the float 4. A second recess 503 is formed on the upper surface of the rotating member 5. The second recess 503 extends from the side of the peripheral wall of the through hole 501 near the float 4 towards the side away from the float 4. When the water level in the water storage chamber drops, the rotating member 5 deflects relative to the axis of the fixed shaft 3. The first recess 502 provides clearance space for the first limiting structure 6, and the second recess 503 provides clearance space for the second limiting structure.
[0067] Of course, in other embodiments, a limiting member can also be provided on the top of the rotating member 5 or the float 4, so that when the water storage cavity is full of water, the highest point of the float 4 floating under the action of buoyancy is limited by the limiting member to the position where the germicidal lamp 2 is facing downward. This will not be elaborated further here.
[0068] In this embodiment, a liquid level sensor and an anti-overflow probe are also provided on the water tank 100. Both the liquid level sensor and the anti-overflow probe are located inside the water storage cavity. The liquid level sensor is used to detect the water level in the water storage cavity so that the user can know the amount of water in the water storage cavity, while the anti-overflow probe is used to prevent the water in the water storage cavity from overflowing.
[0069] This embodiment also provides a water purification device, which includes the water tank 100 as described above.

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.
