Technical Field

[0001] This utility model belongs to the field of filter screen technology, specifically relating to a filter screen structure for a wastewater collection box of a cleaning machine. Background Technology

[0002] An ultrasonic cleaner is a device that uses the principle of high-frequency sound wave vibration to clean the surface of objects. The wastewater collection tank is connected to the ultrasonic cleaner through a drain pipe. When the ultrasonic cleaner is cleaning the workpiece, the wastewater will flow into the wastewater collection tank through a specific drainage channel and drain pipe under the action of gravity or pressure. A filter screen is installed at the inlet of the wastewater collection tank. During the process of wastewater flowing in, larger solid impurities, such as metal shavings, dirt particles, and fibers, will be intercepted by the filter screen to prevent these impurities from entering the collection tank and causing blockage or affecting subsequent processing.

[0003] Existing cleaning machines use filter screens to filter wastewater when collecting it through a wastewater collection tank. The filter screens are conventionally bolted to the wastewater collection tank. Bolt installation requires tools to disassemble each screen individually. Especially after long-term use, the bolts may rust or become stuck due to wastewater corrosion and impurity accumulation. The disassembly process is time-consuming and laborious, affecting the frequency and efficiency of filter screen cleaning and indirectly increasing the risk of filter screen clogging. Therefore, this utility model proposes a filter screen structure for the wastewater collection tank of a cleaning machine. Utility Model Content

[0004] The purpose of this utility model is to provide a filter screen structure for a wastewater collection tank of a cleaning machine, so as to solve the problems mentioned in the background art, which are caused by the conventional bolt installation method, which makes the installation of the filter screen and the wastewater collection tank inconvenient to operate and increases the risk of clogging.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter screen structure for a wastewater collection tank of a cleaning machine, comprising a wastewater collection tank disposed on the side of the cleaning machine, a filter screen disposed inside the wastewater collection tank, and an installation mechanism disposed between the filter screen and the wastewater collection tank, the installation mechanism comprising a support column and a locking assembly, the support column being disposed on the side of the filter screen, and the end of the support column being fixed to the inner side of the wastewater collection tank, and the locking assembly being disposed at the connection between the filter screen and the wastewater collection tank.

[0006] Preferably, the cross-section of the support column is rectangular.

[0007] Preferably, the locking assembly consists of a locking block, a movable groove, a pushing component, a silicone seat, and a locking slot. The movable groove is located inside the sewage collection tank, the locking slot is located on the side of the filter screen, the locking block is located inside the movable groove and the locking slot, the pushing component is located at the connection between the top of the locking block and the movable groove, and the silicone seat is located at the connection between the end of the locking block and the end of the locking slot.

[0008] Preferably, the inner wall edge of the silicone seat has an inclined structure.

[0009] Preferably, the pushing component consists of a push block and a push groove. The push groove is located at the top of the sewage collection tank and is connected to the movable groove. The push block is located inside the push groove, and the bottom end of the push block is fixed to the top end of the locking block.

[0011] Preferably, a drain pipe is installed on the side of the cleaning machine, and the output end of the drain pipe is inserted into the inside of the filter screen.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By designing a new filter and installation mechanism, this system improves upon the previous method where wastewater from the cleaning machine was discharged into the wastewater collection tank through a drain pipe. The filter, installed with conventional bolts, required tools to remove each bolt individually, leading to cumbersome operation. Furthermore, after prolonged use, the bolts could rust or become stuck due to wastewater corrosion and impurities, increasing the risk of filter clogging. The new system uses a snap-fit ​​installation method, eliminating the need for tools and allowing for manual push-pull operation. This significantly reduces cleaning time and facilitates frequent maintenance by operators. It offers advantages in ease of operation, maintenance efficiency, and long-term stability, making it particularly suitable for scenarios requiring frequent filter cleaning of the wastewater collection tank.

[0019] 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.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a filter screen structure for a wastewater collection tank of a cleaning machine, including a wastewater collection tank 2 disposed on the side of the cleaning machine 1, a filter screen 3 disposed inside the wastewater collection tank 2, and an installation mechanism disposed between the filter screen 3 and the wastewater collection tank 2. The installation mechanism consists of support columns 31 and engaging components 32. The support columns 31 are disposed on the side of the filter screen 3, and the ends of the support columns 31 are fixed to the inner side of the wastewater collection tank 2. During the installation of the filter screen 3, the filter screen 3 is initially engaged within the area formed by the symmetrically arranged support columns 31, and then limited and engaged by the engaging components 32. Component 32 is located at the connection between filter screen 3 and sewage collection tank 2. Through the designed filter screen 3 and installation mechanism, it improves the original process where sewage generated by the cleaning machine 1 is discharged into the sewage collection tank 2 through the drain pipe 4. While the filter screen 3 filters the sewage, the conventional method of bolting the filter screen 3 to the sewage collection tank 2 requires tools to disassemble each bolt individually, which is cumbersome. Especially after long-term use, the bolts may rust or become stuck due to sewage corrosion and impurity accumulation, making disassembly time-consuming and laborious, indirectly increasing the risk of filter screen clogging. The filter screen 3 is installed by a snap-fit ​​mechanism with the sewage collection tank 2. No tools are required; the filter screen 3 can be disassembled and installed manually by pushing and pulling, significantly reducing cleaning time and facilitating frequent maintenance by operators. It offers advantages in ease of operation, maintenance efficiency, and long-term stability, making it particularly suitable for scenarios where the sewage collection tank 2 requires frequent cleaning of the filter screen 3. The support column 31 has a rectangular cross-section. The snap-fit ​​assembly 32 consists of a snap-fit ​​block 321, a movable groove 322, a pushing assembly 323, a silicone seat 324, and a slot 325. The movable groove 322 is located within the sewage collection tank. Inside the box 2, a slot 325 is opened on the side of the filter screen 3. A block 321 is set inside the movable groove 322 and inside the slot 325. The filter screen 3 and the sewage collection box 2 are locked together by the locking component 32. The pushing component 323 is set at the connection between the top of the block 321 and the movable groove 322. A silicone seat 324 is set at the connection between the end of the block 321 and the end of the slot 325. The inner wall edge of the silicone seat 324 is inclined. A drain pipe 4 is installed on the side of the cleaning machine 1. The output end of the drain pipe 4 is inserted into the inside of the filter screen 3.

[0021] In this embodiment, preferably, the pushing component 323 consists of a pushing block 3231 and a pushing groove 3232. The pushing groove 3232 is opened on the top of the sewage collection tank 2, and the pushing groove 3232 is in communication with the movable groove 322. The pushing block 3231 is disposed inside the pushing groove 3232. The bottom end of the pushing block 3231 is fixed to the top end of the locking block 321. The pushing component 323 is used to move the locking block 321. The top end of the pushing block 3231 is at the same level as the top end of the sewage collection tank 2.

[0022] The working principle and usage process of this utility model are as follows: During operation, the cleaning machine 1 is connected to the sewage collection tank 2 through the drain pipe 4. When the cleaning machine 1 is cleaning the workpiece, the sewage after cleaning will flow into the sewage collection tank 2 through the specific drainage channel and drain pipe 4 under the action of gravity or pressure. During the process of the sewage flowing into the sewage collection tank 2 through the drain pipe 4, larger solid impurities, such as metal fragments, dirt particles, and fibers, will be intercepted by the filter screen 3 installed inside the sewage collection tank 2, preventing these impurities from entering the sewage collection tank 2 and causing blockage or affecting subsequent processing.

[0023] When the impurities trapped inside the filter screen 3 accumulate to a certain extent, the filter screen 3 is disassembled and cleaned. First, the locking component 32 between the filter screen 3 and the sewage collection tank 2 is operated. The push block 3231 is pushed so that it slides inside the push groove 3232, causing the locking block 321 to move inside the movable groove 322 and inside the silicone seat 324. This causes the end of the locking block 321 to separate from the silicone seat 324 and be stored inside the movable groove 322, thus removing the restriction between the filter screen 3 and the sewage collection tank 2. Then, the filter screen 3 is moved upward to separate it from the support column 31, completing the disassembly of the filter screen 3. Finally, the filter screen 3 is cleaned.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
