The electromagnetic vibration device includes a vibration column at least partially disposed within the installation channel and an electromagnetic coil disposed outside the installation channel.

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 a scattered light distribution. The difference in radiation intensity between the center and edges of the lamp is significant, meaning areas far from the light source or receiving side-irradiation receive doses far below the sterilization threshold, creating a breeding ground for bacteria. Furthermore, the complex internal structure of the water tank (including filters, baffles, and inlet / outlet pipes) makes it easy for the fixed light source to be blocked, creating permanent shadow areas (such as corners and recesses) where UV rays cannot penetrate or reflect. These shortcomings of existing water purifiers lead to a persistent risk of biofilm growth within the tank, reducing water safety and potentially causing secondary pollution, posing health risks to users with long-term use. Current solutions rely on increasing the number of lamps or extending irradiation time, but these do not address the root cause 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 an electromagnetic vibration device. An installation channel extending perpendicularly to the side wall of the water storage tank is formed therein. The installation channel communicates with the inner cavity of the water storage tank. The electromagnetic vibration device includes at least a vibration column partially disposed in the installation channel and an electromagnetic coil disposed outside the installation channel. One end of the vibration column is provided with a magnetic element. When the electromagnetic coil is energized, it acts on the magnetic element through a changing magnetic field, causing the magnetic element to drive the vibration column to vibrate reciprocally.

[0009] To facilitate the installation and fixation of the vibrating column and the transmission of vibration to the wall of the water storage tank, an elastic connecting plate extending laterally is provided at the end of the vibrating column away from the magnetic component. This elastic connecting plate is directly or indirectly fixed to the inner wall of the water storage tank. The elastic connecting plate amplifies the vibration amplitude, evenly transmits the vibration to the tank wall, and enhances the removal of microorganisms from corners.

[0010] To ensure the secure installation of the vibrating column, there are two elastic connecting plates, which are symmetrically arranged relative to the vibrating column.

[0011] As an improvement, the vibrating column is made of sheet metal. Using sheet metal allows for increased vibration frequency through its elasticity, thereby enhancing peeling efficiency.

[0012] To facilitate processing and reduce production costs, the vibration column and the elastic connecting plate are integrated as one piece.

[0013] As an improvement, the vibrating column is axially hollow, and an opening communicating with the interior of the vibrating column is provided at the end away from the magnetic component. The axially hollow vibrating column, with its lightweight design, reduces drive energy consumption. On the other hand, the hollow and open design of the vibrating column increases the contact surface with the water flow, which can better transfer vibration energy to the water flow in the storage tank during vibration. The opening enhances the cavitation effect and improves the microbial stripping rate.

[0014] To form the aforementioned installation channel and facilitate the installation of the electromagnetic coil, the bottom of the side wall of the water storage tank has an outwardly protruding boss, the installation channel is constructed inside the boss, and the electromagnetic coil is sleeved on the outside of the boss.

[0015] To protect the electromagnetic coil, a protective sleeve is also included, which is fitted over the electromagnetic coil and the boss. Adding the protective sleeve provides physical protection, moisture resistance, and insulation, ensuring long-term reliability.

[0016] As an improvement, a reflector is also provided inside the water tank. The reflector is located adjacent to the ultraviolet lamp, and the side of the reflector facing the ultraviolet lamp has a concave reflective surface with a notch facing the ultraviolet lamp. The reflector can be adjusted relative to the ultraviolet lamp by a drive mechanism, thereby reflecting the ultraviolet light emitted by the ultraviolet lamp from the concave reflective surface to different areas inside the water tank.

[0017] The aforementioned "concave reflecting surface" can be understood as an inwardly concave curved surface used to focus or directionally reflect light. Examples include arcs (such as parabolic cross sections), spheres, and ellipsoids.

[0018] The concave reflective surface of the aforementioned water purifier's reflector effectively concentrates the scattered light from the ultraviolet lamps, focusing the originally dispersed radiation energy onto the target area. This significantly increases the ultraviolet intensity per unit area, allowing microorganisms to accumulate to a critical sterilization dose within a very short irradiation time, effectively solving the problem of residual live bacteria due to insufficient dosage when water flows through at high speeds. Furthermore, the drive mechanism adjusts the reflector's position in real time, actively covering shadow areas (such as filter gaps and pipe wall grooves) within the water tank that traditional fixed light sources cannot reach. Through periodic scanning irradiation, physical blind spots for biofilm growth are completely eliminated, blocking secondary pollution sources. The reflector's directional reflection characteristics enable efficient use of ultraviolet energy, reducing the number of lamps or shortening the irradiation time while maintaining the same sterilization effect. Compared to traditional solutions, this effectively reduces energy consumption, and the adjustable design avoids over-configuration of light sources to cover dead areas, significantly reducing maintenance costs. The water purifier solution proposed in this application solves the technical problems of ultraviolet intensity dilution and uneven coverage by redesigning the optical path and dynamically controlling it. It achieves disinfection of the entire water tank without dead corners while ensuring instant sterilization effect, thus comprehensively improving water quality safety and system economy.

[0019] Generally, ultraviolet (UV) lamps can be UV bulbs (point light sources), UV tubes (i.e., line light sources), or surface light sources formed by combining multiple UV bulbs or tubes. Preferably, to better adapt to water purifiers, the UV lamp is a vertically extending UV tube. Since the light from a linear UV tube diverges radially, the reflector shape needs to be optimized for efficient light focusing and to fit the tube structure. Specifically, the reflector is elongated, and its extension direction is consistent with the length direction of the UV tube. The cross-section of the concave reflective surface of the reflector is arc-shaped. The arc-shaped reflective surface of the reflector can directionally reflect UV light to the target area, reducing light energy loss; the elongated reflector is parallel to the tube, achieving uniform longitudinal reflection, which is suitable for the disinfection needs of deep water tanks.

[0020] To simplify the movement of the reflector and ensure the reflection effect of ultraviolet light, the reflector rotates around or parallel to the axis of the ultraviolet lamp under the drive mechanism. It is understood that the movement of the reflector relative to the ultraviolet lamp is not limited to rotation around a set axis; it can also be linear motion or a combination of linear motion and rotational motion (including rotation around an axis or rotation at a hinge point).

[0021] To ensure the reflector maintains a stable relative position with the lamp tube during rotation, guaranteeing a controllable reflected light path and avoiding mechanical interference, the reflector is improved by including a first side edge and a second side edge opposite to each other. The first side edge is positioned against the ultraviolet lamp tube, while the second side edge is positioned away from the ultraviolet lamp tube. The axis of rotation of the reflector relative to the ultraviolet lamp tube coincides with or is adjacent to the central axis of the ultraviolet lamp tube. This structural design also allows the reflector to be as close as possible to the ultraviolet lamp tube and minimizes the space occupied by the reflector during rotation within the water tank, reducing interference with other components within the water tank.

[0022] To facilitate connection with the reflector and to meet the requirement that "the axis of rotation of the reflector relative to the UV lamp tube coincides with or is adjacent to the central axis of the UV lamp tube", the top of the reflector has a connecting end cap extending toward the location of the UV lamp tube. The driving mechanism is a drive motor located on the top of the water tank, and the output shaft of the drive motor is connected to the connecting end cap to drive the reflector to rotate.

[0023] Compared with existing technologies, the advantages of this invention are as follows: The vibrating column of the electromagnetic vibration device generates high-frequency horizontal vibration under electromagnetic drive, directly acting on the side walls and corners of the water storage tank. This effectively shakes off the microbial film adhering to the inner wall, grooves, or the back of the filter element, suspending it in the water. This solves the problem of "permanent shadow areas" caused by fixed irradiation of traditional ultraviolet lamps. The suspended microorganisms are exposed to the ultraviolet radiation range, completely eliminating sterilization blind spots. Continuous water disturbance also promotes the uniform diffusion of ultraviolet light to dead corners, increasing the radiation dose per unit area, ensuring complete inactivation of microorganisms, and blocking biofilm regeneration at the source. This invention does not require increasing the number of ultraviolet lamps or extending the irradiation time; it significantly improves sterilization efficiency through physical vibration alone, avoiding the high energy consumption and maintenance costs of traditional solutions, while extending the lifespan of the ultraviolet lamps. In the preferred embodiment, the vibrating column is built-in through a side wall mounting channel, and the external electromagnetic coil design balances sealing and vibration transmission efficiency, making it particularly suitable for complex water storage tanks without occupying internal water purification space.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] 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.

[0032] Figures 1-6 This illustration shows a preferred embodiment of the water purifier of this utility model. The water purifier with disinfection function in this embodiment includes a water tank 10, an ultraviolet lamp 2, a reflector 3, a drive mechanism, and an electromagnetic vibration device. The water tank 10 consists of a tank body 11 with an open top and a cover 12 detachably fitted onto the tank body 11. The outer periphery of the cover 12 is connected to the tank body 11 via a snap-fit. The detachable cover 12 facilitates the installation of the components within the water tank 10 and subsequent maintenance and cleaning. The ultraviolet lamp 2 is a vertically extending ultraviolet lamp tube (linear light source), cylindrical in shape. Its lower end is fixed through a second mounting hole on the bottom wall of the water tank 10, with an exposed wire connection end 21 for power supply. The ultraviolet lamp tube extends from bottom to top to the adjacent top wall of the water tank 10, thus essentially penetrating the height of the tank, allowing for comprehensive disinfection of the water within the tank.

[0033] See Figure 1 The water storage tank 10 is a flat, box-shaped structure. The aforementioned ultraviolet lamp is positioned in the middle area of ​​the length and width of the water storage tank 10.

[0034] See Figure 6The reflector 3 is a long strip-shaped component, extending in the same direction as the length of the ultraviolet lamp tube, with a circular arc-shaped (parabolic) cross-section forming a concave reflective surface 30. This reflective surface faces the ultraviolet lamp tube, with the concave opening directly opposite the tube to focus and scatter ultraviolet light. The concave reflective surface 30 of the reflector 3 can be coated with a reflective coating that easily reflects ultraviolet light. The top of the reflector 3 has a connecting end cap 33 extending horizontally towards the ultraviolet lamp tube for linkage with the drive mechanism. The two opposite sides of the reflector 3 are designated as the first side edge 31 and the second side edge 32, respectively. The first side edge 31 of the reflector 3 is in close contact with the surface of the ultraviolet lamp tube, while the second side edge 32 is away from the tube, thus forming an asymmetrical enclosure structure.

[0035] Combination Figure 2 and Figure 4 The driving mechanism includes a drive motor 4 located on top of the water tank 10. The cover 12 of the water tank 10 has a partially recessed mounting groove 120, within which the drive motor 4 is fixed. The top opening of the mounting groove 120 is sealed by a cap 13. A first mounting hole is formed in the bottom wall of the mounting groove 120, into which a rubber sealing sleeve 121 is fitted. The output shaft 41 of the drive motor 4 passes downward through the sealing sleeve 121 and is rigidly connected to the connecting end cap 33 of the reflector 3. The sealing sleeve 121 ensures the water tank's airtightness during rotation, preventing water leakage. The central axis of the output shaft 41 of the drive motor 4 coincides with the central axis of the ultraviolet lamp, allowing the reflector 3 (driven by the drive motor 4) to rotate around the axis of the ultraviolet lamp. During the rotation of the reflector 3 around the ultraviolet lamp, the first side edge 31 of the reflector 3 remains in close contact with the outer peripheral wall of the ultraviolet lamp, while the distance between the second side edge 32 and the ultraviolet lamp remains essentially constant. The above structural design also allows the reflector 3 to be as close as possible to the ultraviolet lamp tube, and minimizes the space occupied by the reflector 3 during its rotation within the water tank 10, thus reducing interference with other components within the water tank 10.

[0036] See Figure 3 After the ultraviolet lamp is activated, the light is radially scattered to the concave reflective surface 30 of the reflector 3. The arc-shaped reflective surface focuses and directionally reflects the scattered light to a specific area of ​​the water tank 10. The drive motor 4 periodically drives the reflector 3 to rotate around the axis of the ultraviolet lamp (the rotation angle is adjustable from 0° to 360°), allowing the reflected beam to scan different areas inside the water tank. Through the focusing effect of the reflector 3 and continuous rotation, the ultraviolet intensity in the target area can be effectively increased (compared to the unfocused state), ensuring that microorganisms reach the critical bactericidal dose instantly and eliminating the risk of biofilm growth in the shaded areas. Figure 4 The dashed section shows the reflector 3 in a state of rotation to another angular position.

[0037] In this embodiment, the concave reflective surface 30 of the reflector 3 of the water purifier effectively concentrates the scattered light from the ultraviolet lamp 2, reflecting the originally dispersed radiation energy to the target area. The ultraviolet intensity per unit area can be significantly increased, allowing microorganisms to accumulate to the critical sterilization dose within a very short irradiation time, effectively solving the problem of insufficient dose leading to residual live bacteria when water flows through at high speed. Based on this, the drive mechanism adjusts the position of the reflector 3 in real time, actively covering shadow areas (such as filter gaps and pipe wall grooves) within the water tank 10 that cannot be illuminated by traditional fixed light sources. Through periodic scanning irradiation, physical blind spots for biofilm growth are completely eliminated, blocking secondary pollution sources. The directional reflection characteristics of the reflector 3 enable efficient utilization of ultraviolet energy, reducing the number of lamps or shortening the irradiation time while maintaining the same sterilization effect. Compared to traditional solutions, this effectively reduces energy consumption. Furthermore, the adjustable design avoids over-configuration of light sources to cover dead areas, significantly reducing maintenance costs. The water purifier solution proposed in this application solves the technical problems of ultraviolet intensity dilution and uneven coverage by redesigning the optical path and dynamically controlling it. It achieves disinfection of the entire water tank without dead corners while ensuring instant sterilization effect, thus comprehensively improving water quality safety and system economy.

[0038] See Figure 4 and Figure 5 The lower part of the side wall of the water tank body 11 of the water tank 10 has an outwardly protruding boss 14, which is a horizontally extending cylindrical boss structure. A cylindrical installation channel 140 is opened inside the boss 14. The extension direction of the boss 14 is basically perpendicular to the side wall of the water tank 10, and the installation channel 140 also extends in a direction perpendicular to the side wall and communicates with the inner cavity of the water tank 10.

[0039] The electromagnetic vibration device includes a vibrating column 5, a magnetic component 51, and an electromagnetic coil 6. The vibrating column 5 can be an axially hollow vibrating column 5 integrally formed from 304 stainless steel sheet metal. One end of the column facing the interior of the water storage tank 10 is open, while the other end is closed, with the magnetic component 51, composed of permanent magnets, fixed by adhesive bonding. Two elastic connecting plates 52 extend symmetrically from the open end of the vibrating column 5, distributed 180° symmetrically, and can be fixed to the support column on the inner wall of the water storage tank 10 by screws. The electromagnetic coil 6 is sleeved on the outside of the boss 14. When energized, it generates an alternating magnetic field that drives the magnetic component 51, causing the vibrating column 5 to reciprocate horizontally (e.g., amplitude ±1mm, frequency 50Hz).

[0040] In some embodiments, the electromagnetic coil 6 and the boss 14 are covered by an ABS engineering plastic protective sleeve 61 and fixed to the side wall of the water tank 10 by buckles or screws.

[0041] The working process of the water purifier in this embodiment is as follows: A pulsed current is applied to the electromagnetic coil 6, driving the vibrating column 5 to vibrate at high frequency. This vibration is transmitted to the inner wall of the water storage tank 10 through the elastic connecting plate 52, shaking off the microbial film attached to the corners. The drive motor 4 drives the reflector 3 to rotate, and the concave reflective surface 30 focuses and reflects ultraviolet light to different areas within the water storage tank 10. Suspended microorganisms receive high-intensity ultraviolet radiation in the disturbed water flow, achieving comprehensive sterilization.

[0042] Based on the above embodiments, other embodiments can be obtained by replacing and improving the relevant technical features. For example, the reflector 3 can swing around the side axis of the ultraviolet lamp tube through the hinge point (non-concentric rotation) to achieve fan-shaped area scanning. Alternatively, when the ultraviolet lamp 2 is replaced with a point light source (ultraviolet lamp bulb 2), the reflector 3 is changed to a bowl-shaped ellipsoid with the focal point located at the center of the bulb. A surface light source (multi-lamp array) is configured with multiple independent reflectors 3, each of which rotates synchronously by a linkage mechanism. Furthermore, the drive mechanism uses a linear motor to move the reflector 3 up and down along the length of the ultraviolet lamp tube, solving the problem of uneven longitudinal irradiation. Another example is that the upper end of the ultraviolet lamp tube is suspended from the cover 12, while the lower end is freely suspended; the reflector 3 is connected to the bottom wall of the water tank through a bottom bearing. Of course, the drive motor 4 can also be externally mounted, driving the reflector 3 through the water tank wall via a magnetic coupling transmission device, avoiding sealing problems.
