Water storage type water purifier

Abstract

This utility model relates to a storage-type water purifier, comprising: a water storage tank; an ultraviolet lamp disposed within the water storage tank; and a motion mechanism for moving the ultraviolet lamp within the water storage tank. The ultraviolet lamp includes a lampshade, on which a turbulence-dispersing component is provided. This component stirs the water within the storage tank as the ultraviolet lamp moves. The advantages are: during the lamp's movement, microorganisms in all areas receive high-intensity direct irradiation, overcoming the drawback of excessively large differences in radiation intensity between the center and edge of a fixed lamp. Furthermore, the turbulence-dispersing component moving with the ultraviolet lamp actively agitates the water flow, generating a turbulent effect that breaks up the static water layer. This forces microorganisms deposited on the bottom or side walls of the storage tank to suspend in the high-intensity ultraviolet radiation zone. The microorganisms repeatedly traverse the core sterilization area in the turbulent flow, accumulating sufficient irradiation. Even under high-speed water flow, the critical sterilization dose can be ensured, significantly reducing the risk of viable bacteria residue.

Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and in particular to a storage-type water purifier. Background Technology

[0002] Water purifiers typically use ultraviolet (UV) lamps for sterilization. These UV lamps are usually fixed in place, resulting in a fixed radiation angle and scattered light distribution, significantly diluting the UV intensity per unit area. Microorganisms require a cumulative dose (intensity × time) to be inactivated; this energy dispersion prevents the instantaneous critical sterilization dose from being reached. Especially with fast water flow, some microorganisms may pass through the sterilization zone without sufficient irradiation, posing a high risk of residual live bacteria. The significant difference in radiation intensity between the center and edges of the lamp means that areas far from the light source or under side irradiation receive doses far below the sterilization threshold, becoming breeding grounds for bacteria. Furthermore, the complex internal structure of the water tank (e.g., filters, baffles, inlet / outlet pipes) makes it easy for the fixed light source to be blocked, creating permanent shadow areas (e.g., corners, recesses) where UV light cannot penetrate or reflect. These shortcomings of existing water purifiers lead to a continuous risk of biofilm growth within the tank, reducing water safety and potentially causing secondary pollution, posing health risks to users with long-term use. Existing solutions rely on increasing the number of lamps or extending the illumination time, but these cannot solve the fundamental problem and instead increase energy consumption and maintenance costs.

[0003] Therefore, existing water purifiers still need further improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a storage-type water purifier that can achieve thorough sterilization and disinfection, based on the current state of the existing technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a storage-type water purifier, comprising:

[0006] Water storage tank;

[0007] An ultraviolet lamp is installed inside the water storage tank;

[0008] It also includes a motion mechanism for moving the ultraviolet lamp within the water storage tank. The ultraviolet lamp includes a lampshade, and the lampshade is also provided with a baffle. The baffle stirs the water in the water storage tank as the ultraviolet lamp moves.

[0009] The water purifier's moving mechanism drives the ultraviolet lamp to move within the water tank, actively covering shadowed areas such as corners, the back of partitions, and pipe gaps that traditional fixed light sources cannot reach, effectively eliminating physical blind spots for biofilm growth. During the lamp's movement, microorganisms in all areas receive high-intensity direct radiation, overcoming the drawback of excessively large differences in radiation intensity between the center and edges of fixed lamps. Furthermore, the turbulence-generating components moving with the ultraviolet lamp actively agitate the water flow, creating a turbulent effect that breaks up the static water layer. This forces microorganisms deposited on the bottom or side walls of the water tank to suspend in the high-intensity ultraviolet radiation zone. The microorganisms repeatedly traverse the core sterilization area in the turbulent flow, accumulating sufficient irradiation. Even under high-speed water flow, the critical sterilization dose is ensured, significantly reducing the risk of viable bacteria residue. This dynamic ultraviolet coverage combined with hydraulic agitation disrupts the conditions for microbial attachment and colonization, fundamentally preventing biofilm formation and avoiding secondary pollution. Compared to solutions such as increasing the number of lamps or extending the irradiation time, this solution achieves a more comprehensive sterilization effect by operating a single lamp dynamically, while reducing system energy consumption and maintenance complexity, thus combining high efficiency and economy.

[0010] To simplify the structure of the motion mechanism and ensure comprehensive disinfection of the ultraviolet lamp, the ultraviolet lamp is a horizontally extending ultraviolet tube. The motion mechanism includes a drive motor and a rotating shaft vertically positioned within the water tank, which is driven by the drive motor to rotate around its own axis. One end of the ultraviolet lamp is connected to the rotating shaft, which drives its rotation. This vertical rotating shaft, in conjunction with the horizontal lamp, utilizes rotation to cover the radial area, saving lateral space. The rotational motion causes the turbulence-generating components to create vortices, enhancing the water disturbance effect.

[0011] To facilitate the installation and subsequent maintenance of the drive motor, the drive motor is mounted on top of the water storage tank, and its output shaft is connected to the top of the rotating shaft. Mounting the drive motor on top of the water storage tank avoids the risk of the motor being submerged in water, thus improving waterproofing safety. Furthermore, the motor can be disassembled or replaced without draining the water, facilitating maintenance.

[0012] To facilitate the installation of the drive motor and subsequent maintenance and disassembly, the top wall of the water tank has a recessed mounting groove and a cover that fits over the top opening of the mounting groove. The drive motor is housed in the mounting groove, and its output shaft passes through the bottom wall of the groove and connects to the reflector. The recessed design on the top of the water tank saves external space and keeps the water purifier's appearance neat.

[0013] Considering the need for a tight seal when the motor shaft enters the water tank to prevent water leakage leading to short circuits or contamination, a first through-hole is provided on the bottom wall of the mounting groove. A sealing sleeve is provided at the first mounting hole, and the output shaft of the drive motor passes through the sealing sleeve. The sealing sleeve (such as a rubber ring) effectively fills the gap between the shaft and the hole wall, achieving dynamic rotational sealing.

[0014] For the installation and subsequent maintenance of the various components inside the water tank, the water tank includes a water tank body with an open top and a detachable cover that fits onto the water tank body, and the cover has the aforementioned mounting groove.

[0015] To simplify the assembly structure between the UV lamp and the rotating shaft, a non-circular connecting hole is provided at the end of the UV lamp, and the rotating shaft passes through and connects to the connecting hole. The aforementioned "non-circular connecting hole" can be understood as a hole structure with a non-circular cross-section, used for transmitting torque. Examples include polygonal holes (such as hexagonal holes), keyway holes, and D-shaped holes.

[0016] Generally, a flow disruptor can be a component that can disrupt the stability of water flow through its physical structure. Examples include: flow disruptors, spiral fins, irregular protrusions, etc. Preferably, the flow disruptor includes flow disruptors arranged sequentially along the length of the UV lamp's cover.

[0017] Considering that the baffles perpendicular to the length of the UV lamp tube have low water stirring efficiency and may create unidirectional flow dead zones, each baffle is positioned at the bottom of the UV lamp tube's cover, and the extension direction of each baffle has a certain acute angle relative to the length direction of the UV lamp tube. These inclined baffles can drive the water to form a spiral turbulent flow, improving stirring uniformity. They also optimize fluid resistance and reduce motor noise and energy consumption.

[0018] As an improvement, a controller is also included, which is electrically connected to the drive motor. The controller controls the drive motor to drive the ultraviolet lamp to perform intermittent rotation. The aforementioned "intermittent rotation" can be understood as a periodic "rotation-pause" action, not continuous rotation. For example, the controller is set to pause for 10 seconds after rotating for 30 seconds (or after a certain angle), and the cycle repeats.

[0019] Compared with existing technologies, the advantages of this invention are as follows: The moving mechanism of the water purifier drives the ultraviolet lamp to move within the water tank, allowing ultraviolet light to actively cover shadowed areas such as corners, the back of partitions, and pipe gaps that traditional fixed light sources cannot reach, effectively eliminating physical blind spots for biofilm growth. During the lamp's movement, microorganisms in each area can receive high-intensity direct irradiation, overcoming the defect of excessively large differences in radiation intensity between the center and edge of fixed lamps. Furthermore, the turbulence-generating components that move with the ultraviolet lamp actively agitate the water flow, creating a turbulent effect that breaks up the static water layer. This forces microorganisms deposited on the bottom or side walls of the water tank to suspend in the high-intensity ultraviolet radiation zone. The microorganisms repeatedly traverse the core sterilization area in the turbulent flow, accumulating sufficient irradiation. Even under high-speed water flow, the critical sterilization dose can be reached, significantly reducing the risk of live bacteria residue. This dynamic ultraviolet coverage combined with hydraulic agitation can disrupt the conditions for microbial attachment and colonization, fundamentally preventing biofilm formation and avoiding secondary pollution. Compared to solutions such as increasing the number of lamps or extending the irradiation time, this solution achieves a more comprehensive sterilization effect by operating a single lamp dynamically, while reducing system energy consumption and maintenance complexity, thus combining high efficiency and economy.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0025] Figures 1-3A preferred embodiment of the storage-type water purifier of this utility model is shown. The storage-type water purifier of this embodiment includes: a water tank body 11 with an open top, a cover 12 detachably fitted to the top of the water tank body 11, an ultraviolet lamp 2 disposed inside the water tank body 11, a motion mechanism for driving the ultraviolet lamp 2, and a controller for controlling the motion mechanism. A baffle 22 is provided at the bottom of the lampshade 20 of the ultraviolet lamp 2. When the motion mechanism drives the ultraviolet lamp 2 to rotate, the baffle 22 synchronously agitates the water flow, achieving a dual effect of dynamic sterilization and water mixing.

[0026] In this embodiment, the water tank 10 is a flat tank body, specifically including a tank body 11 and a cover 12. The cover 12 is detachably fixed to the top of the tank body 11 by a snap-fit ​​assembly, facilitating internal cleaning or component replacement. The top of the cover 12 is provided with a mounting groove 120. Specifically, the surface of the cover 12 is partially recessed to form a square or circular receiving cavity (i.e., mounting groove 120), the top of which is open and sealed by a cap 13, and the bottom has a through first mounting hole.

[0027] The motion mechanism includes a drive motor 3 and a rotating shaft 32 connected to the output shaft 31 of the drive motor 3. The drive motor 3 is fixed in the mounting groove 120 of the cover 12, and the output shaft 31 extends vertically downward. A rubber sealing sleeve 121 is embedded in the first mounting hole, and the output shaft 31 of the drive motor 3 passes through the sealing sleeve 121 and extends into the water storage tank 10 to connect with the rotating shaft 32, achieving dynamic rotational waterproofing. It can be understood that the rotating shaft 32 and the output shaft 31 of the drive motor 3 can be a single piece, such as formed by welding or other methods; or they can be separate parts, such as connected by a coupling. The rotating shaft 32 is also vertically arranged and can be a metal shaft or a plastic rod.

[0028] See Figure 3 In this embodiment, the ultraviolet lamp 2 is a horizontally extending ultraviolet lamp tube, which includes a lamp cover 20 and a light source emitting ultraviolet light disposed inside the lamp cover 20. A hexagonal connecting hole 21 (not a circular hole) is opened at one end of the ultraviolet lamp tube, and the bottom end of the rotating shaft 32 is inserted into the hole to form a torque transmission structure. Of course, alternatively, the connecting hole 21 can also be a D-shaped hole or a circular hole with a keyway, and the rotating shaft 32 is provided with a matching cross section.

[0029] The baffle 22 at the bottom of the UV lamp cover 20 can be composed of multiple baffles, which are equidistantly arranged along the length of the bottom of the UV lamp cover 20. Each baffle is tilted at a 30° acute angle relative to the length of the UV lamp, and the tilt direction can be the same as the rotation direction. The tilted baffles, during rotation, push the water body to form a spiral turbulence, causing sedimented microorganisms to suspend in the high-intensity UV radiation zone. The material of each baffle can be the same as that of the lamp cover 20; that is, the baffle can be integrally formed with the lamp cover 20. Alternatively, the baffles can be detachably connected to the bottom of the lamp cover 20 via a plug-in connection.

[0030] The drive motor 3 is electrically connected to the water purifier's controller, which can preset intermittent operation programs: such as pausing for 5 seconds after every 15 degrees of rotation. This allows for targeted and programmed cleaning of certain areas according to a predetermined program. On the other hand, the pause period also allows microorganisms to diffuse into the radiation core area with the turbulent flow, increasing the cumulative radiation dose while reducing motor energy consumption.

[0031] In this embodiment, the motion mechanism of the water purifier drives the ultraviolet lamp 2 to move within the water storage tank 10, allowing ultraviolet light to actively cover shadowed areas such as corners, the back of partitions, and pipe gaps that traditional fixed light sources cannot reach, effectively eliminating physical blind spots for biofilm growth. During the lamp's movement, microorganisms in each area can receive high-intensity direct irradiation, overcoming the drawback of excessively large differences in radiation intensity between the center and edge of a fixed lamp. Furthermore, the turbulence-inducing component 22, moving with the ultraviolet lamp 2, actively agitates the water flow, generating a turbulent effect that breaks up the static water layer. This forces microorganisms deposited on the bottom or side walls of the water storage tank 10 to suspend in the high-intensity ultraviolet radiation zone. The microorganisms repeatedly traverse the core sterilization area in the turbulent flow, accumulating sufficient irradiation. Even under high-speed water flow, the critical sterilization dose can be reached, significantly reducing the risk of live bacteria residue. This dynamic ultraviolet coverage combined with hydraulic agitation disrupts the conditions for microbial attachment and colonization, fundamentally preventing biofilm formation and avoiding secondary pollution. Compared to solutions such as increasing the number of lamps or extending the irradiation time, this solution achieves a more comprehensive sterilization effect by operating a single lamp dynamically, while reducing system energy consumption and maintenance complexity, thus combining high efficiency and economy.
