Description

Technical Field

[0001] This utility model relates to cleaning devices, and more particularly to an ultrasonic cleaning device that can achieve water recycling. Background Technology

[0002] Existing water circulation filters (with disclosed structure: filter base, miniature submersible pump, pump gland, screw cap, inner gland, O-ring, PP cotton filter element) have revealed the following defects in actual use: 1. Difficult to disassemble and assemble – When replacing the filter element, the entire “pump + filter element” assembly must be removed. It is necessary to lift it up and deform the cleaning basket in part to unlock it. Operators need to master specific skills, otherwise it is easy to cause fatigue fracture of plastic parts. 2. High water resistance - The original water outlet is located at the cap end and faces the side wall of the cleaning tank. The side wall is close to the water outlet, which creates backflow resistance. When the filter element is about to become clogged, the water output drops sharply, and users cannot predict this in advance. 3. Requires a separate adapter – The C105 miniature submersible pump relies on an external DC12V adapter, increasing the number of desktop cables, and the entire unit becomes unusable if the adapter is lost, resulting in poor versatility; 4. Complex fixed structure - requires additional composite filter brackets and fan platform frames, which takes up extra space, has a messy appearance, and the laser-cut brackets need to be repeatedly adjusted for different models, resulting in high production costs; 5. Filter cartridge missing warning - The current solution does not have a clogging warning. Users often only find that the filter cartridge is saturated when the water flow is extremely low, which leads to repeated contamination of the cleaning solution and reduces cleaning efficiency.

[0003] Therefore, the market urgently needs a water circulation filtration solution that is easy to install and disassemble, has low resistance, universal power supply, can be integrated with the cleaning basket, and has a clogging indicator. Summary of the Invention

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Figure 1 This is an exploded view of the water circulation filter and cleaning basket, specifically including the water pump fastening bracket 51, O-ring seal 52, DC12V submersible pump 53, bracket pressure block 54, cleaning basket handle 55, plastic cleaning basket 56, filter bottom shell 57, filter element bottom sealing ring 58, 10μm PP cotton filter element 59, filter element top sealing ring 510, and screw cap 511.

[0017] The filter base 57 can be made of one-piece injection-molded ABS, with an internal partition dividing it into a "filter cartridge compartment" and a "pump compartment". The filter cartridge compartment has an annular boss on its inner wall for axial positioning of the filter cartridge bottom sealing ring 58. The pump compartment has two limiting ribs at its bottom, which engage with the snap-fit ​​on the pump mounting bracket 51 to achieve a three-step fixation: "push-in - rotate - lock". Alternatively, four screw holes can be provided in the middle of the pump mounting bracket 51. The top and bottom two screw holes are used to fix the pump mounting bracket 51 and the filter base 57. The two middle screw holes of the pump mounting bracket 51 are used to fix the cleaning frame. The upper left corner of the pump mounting bracket 51 is a fixing block for the bracket 54.

[0018] Submersible pump 53 is a standard miniature centrifugal pump powered by DC 12V, with a two-pin DC plug at the outlet. The pump outlet is a straight pipe with a diameter of φ4~8mm, which is interference-fitted with the side wall hole of the filter bottom shell 57, eliminating the need for a hose and preventing it from falling off.

[0019] The filter element assembly includes a 10μm PP cotton filter element 59, which is a hollow cylinder with grooves and matching annular ribs that correspond to the bottom sealing ring 58 and the top sealing ring 510. Both sealing rings are silicone O-rings, which are axially compressed by the cap 511 after assembly to form an end face seal.

[0020] The cap 511 has an annular rib on its inner end face for synchronously pressing the top sealing ring 510 of the filter element. The central hole is coaxial with the inner hole of the filter element, forming a direct injection channel.

[0021] Among them, the detachable stainless steel bracket is 66. Figure 2 This is a schematic diagram of an independently extended water circulation filter. The stainless steel plate is laser-cut and then folded at 90° to form two symmetrical clamping claws. The clamping claw spacing can be adjusted on-site according to the hole spacing on the side wall of the target cleaning machine, without the need for molds.

[0022] Figure 3 This is a diagram showing the disassembly and replacement of the filter element in an existing water circulation filter. The filter element needs to be pushed upwards by more than 3 mm before being pushed downwards to allow the retaining clip to be in place. The reverse operation requires removing the entire filter before the filter element can be replaced.

[0023] Figure 4 This is a schematic diagram of the water circulation filter of this utility model for replacing the filter element; the filter element can be cleaned or replaced simply by unscrewing the cap from the side.

[0024] Detailed working principle of water circulation filter 1. Suction stage: The entire filter is submerged in the cleaning solution. After the submersible pump 53 is powered on, a negative pressure is generated at the pump inlet. The liquid first enters the pump chamber through the grid at the bottom of the filter housing 57 pump compartment; the grid can block large particles and prevent the pump impeller from getting stuck.

[0025] 2. Water pressure stage: The impeller pushes the liquid out of the pump outlet tangentially, and the liquid directly enters the side wall hole of the filter cartridge chamber. The flow velocity increases instantly, forming a vortex, which makes the liquid evenly distributed on the outer surface of the filter cartridge and avoids local blockage.

[0026] 3. Filtration stage: The swirling liquid radially penetrates the outer wall of the 10μm PP cotton filter element 59, and particulate matter is trapped by the PP cotton fibers; the clean liquid flows upward along the central channel of the filter element. The top sealing ring 510 and the bottom sealing ring 58 of the filter element form an end face seal under the axial compression of the screw cap 511, ensuring that the liquid can only pass through the filter element and there is no bypass leakage.

[0027] 4. Spraying stage: After the clean liquid reaches the top of the filter element, it is sprayed vertically through the central hole of the cap 511, forming a stable water column that directly sprays onto the surface of the object being washed. As the filter element gradually becomes saturated, the water flow from the central hole decreases linearly. Users can visually recognize the decrease in water flow and replace the filter element in advance.

[0028] The cleaning basket is integrally injection molded ABS, and its shape matches the cleaning tank. The side wall is an integrally molded cylindrical filter housing. An opening is provided on the plastic cleaning basket 56 at a position matching the small circular hole in the central disc of the filter base 57, allowing the filter water to flow directly into the basket through this opening. Reinforcing ribs are provided around the perimeter to ensure no deformation during long-term hanging. The cleaning basket handle 55 can be made of stainless steel wire wrapped in TPR, with both ends directly inserted into the pre-set locking holes in the cleaning basket 56. The assembled water circulation filter is axially inserted into the housing of the plastic cleaning basket 56; the Ω-shaped buckle of the water pump mounting bracket 51 engages with the boss on the housing wall. The water pump mounting bracket 51 has four screw holes in the middle; the top and bottom two screw holes are used to fix the water pump mounting bracket 51 and the filter base 57. The two middle screw holes of the water pump mounting bracket 51 are used to fix the cleaning frame. The upper left corner of the water pump mounting bracket 51 is a fixing block for the bracket 54.

The stainless steel tank generator assembly 8 is fixed below the inner cover 3 to realize ultrasonic vibration transmission. The right handle 5 and the left handle 26 are symmetrically engaged on both sides of the pressure ring 4 for handling the entire machine.

[0030] 2. Control and Power Supply System: The main PCB board 10 and the socket PCB board 15 are connected via pin headers. The socket PCB board 15 integrates an AC socket 18, a DC socket 16, and a rocker switch 17. The control PCB board 25 is mounted on the control box bracket 24. The control panel lens 23 is attached to the surface of the control box bracket 24 and is electrically connected to the rocker switch 17 to realize the on / off, timer, and heating start / stop of the whole machine.

[0031] 3. Heating system: Ceramic heater 22 is attached to the bottom of inner cylinder 9; ceramic insulation cotton 21 and double-layered ceramic heater 22 are pressed together by heater bottom cover 19 and heater top cover 20 to prevent heat from dissipating.

[0032] 4. Heat dissipation system: The cooling fan 13 is inserted into the cooling fan cover 12, and the fan cover is fixed to the side wall of the bottom shell 11 with screws; the water baffle 14 is located above the fan to prevent condensate from entering the fan.
