Description

Technical Field

[0001] This invention relates to the field of ultrasonic cleaning technology, and more specifically to an ultrasonic cleaning machine that is easy to clean. Background Technology

[0002] Ultrasonic cleaning machines utilize the cavitation effect of ultrasound to clean items and are widely used in cleaning various materials. However, existing technologies have significant drawbacks. For example, traditional cleaning tanks are often rigidly connected to the shell and transducer using methods such as welding or bolting, making it difficult to thoroughly clean residual dirt from the inner wall of the cleaning tank. For instance, Chinese Patent Publication No. CN221773035U discloses an easy-to-clean ultrasonic cleaning machine that uses a built-in brushing mechanism to clean the bottom of the inner tank. While this can improve bottom cleaning in some areas, the brushing components are complex to disassemble, prone to accumulating dirt, and require multiple rinses to remove dirt from the side walls, which is time-consuming, labor-intensive, and affects the cleaning effect. Utility Model Content

[0003] To address the aforementioned issues, this invention provides an easy-to-clean ultrasonic cleaner. Through the design of the drive unit, pull ring, and positioning components, the cleaning tank is detachably mounted on the housing. Users can completely detach the cleaning tank from the housing without the need for tools or complex operations, allowing for comprehensive direct wiping, rinsing, or soaking of its inner walls, bottom, and corners. This avoids the risk of secondary contamination caused by the inability to deeply clean traditional fixed structures.

[0004] To address the problems of existing technologies, this invention provides an easy-to-clean ultrasonic cleaner, comprising a housing and a cleaning tank disposed on the housing. An ultrasonic transducer for driving the cleaning tank to vibrate is disposed inside the housing, and the ultrasonic transducer is fixedly connected to the bottom of the housing. Driving components are pivotally connected to the side walls on both sides of the housing, and each driving component has a rotatable pull ring. A connecting component corresponding to the pull ring is disposed on the cleaning tank. Rotatable positioning components are disposed on the side walls on both sides of the inner side of the housing, and the positioning components are drive-connected to the driving components. When the driving components rotate, they synchronously drive the pull ring and the positioning components to fix the cleaning tank.

[0005] Preferably, a transmission component that can slide horizontally is provided on the side wall of the housing, and a sliding groove extending vertically is provided at the bottom of the driving component. One end of the transmission component slides in conjunction with the sliding groove, and a connecting rod hinged to the middle of the positioning component is provided therewith. The connecting rod is hinged to the other end of the transmission component.

[0006] Preferably, a rotatable roller is provided at the end of the positioning member away from the housing, and a groove matching the roller is provided on the outer wall of the cleaning tank at the position corresponding to the roller.

[0007] Preferably, both sides of the top of the housing are provided with clearance grooves to avoid the connecting parts.

[0008] Preferably, the bottom of the cleaning tank is provided with a connection groove that matches the ultrasonic transducer.

[0009] Preferably, the top of the housing is provided with a receiving platform extending along its contour, and a guide post is fixedly provided on the receiving platform; the top of the cleaning tank is provided with an extension edge that matches the receiving platform, and a guide hole adapted to the guide post is opened on the extension edge.

[0010] The advantages of this invention compared to the prior art are:

[0011] 1. In use, the cleaning tank is placed inside the housing. By rotating the drive component, the drive component rotates around the pivot shaft. At this time, through the cooperation of the pull ring and the connecting component, the pull ring can pull the cleaning tank to the bottom of the housing. Simultaneously, the rotation of the drive component will drive the positioning component connected to it to move, causing the positioning component to rotate towards the outer wall of the cleaning tank until the positioning component abuts against the outer wall of the cleaning tank. Under the constraint of the pull ring and the positioning component, the cleaning tank is in close contact with the ultrasonic transducer, ensuring efficient transmission of vibration energy to achieve the cleaning function. This detachable setting solves the problem of inconvenient cleaning caused by the fixed connection of the cleaning tank in traditional cleaning machines from the structural source. Users can completely detach the cleaning tank from the housing without the need for tools or complicated operations, and directly wipe, rinse or soak its inner wall, bottom and corners from all directions, thoroughly removing dirt, residues and microorganisms that have accumulated after long-term use, avoiding the risk of secondary pollution caused by the inability to deeply clean traditional fixed structures.

[0012] 2. The present invention, through the setting of grooves and rollers, provides clear positioning guidance for the rollers, ensuring that the cleaning tank can be quickly and accurately aligned with the ultrasonic transducer during installation, thereby improving the stability of vibration transmission; while during disassembly, the rolling characteristics of the rollers make the separation process of the positioning component from the cleaning tank smoother and less labor-intensive, avoiding jamming problems caused by excessive frictional resistance, and further enhancing the convenience of disassembling the cleaning tank.

Detailed Implementation

[0024] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 8 As shown: An easy-to-clean ultrasonic cleaner includes a housing 1 and a cleaning tank 12 disposed on the housing 1. An ultrasonic transducer 11 for driving the cleaning tank 12 to vibrate is disposed inside the housing 1, and the ultrasonic transducer 11 is fixedly connected to the bottom of the housing 1. A driving member 13 is pivotally connected to the side walls on both sides of the housing 1, and a rotatable pull ring 131 is disposed on the driving member 13. A connecting member 121 corresponding to the pull ring 131 is disposed on the cleaning tank 12. Rotatable positioning members 14 are disposed on the side walls on both sides inside the housing 1, and the positioning members 14 are connected to the driving member 13 through a transmission. When the driving member 13 rotates, it can synchronously drive the pull ring 131 and the positioning member 14 to fix the cleaning tank 12.

[0026] In use, the cleaning tank 12 is placed inside the housing 1. By rotating the drive member 13, the drive member 13 rotates around the pivot shaft. At this time, through the cooperation of the pull ring 131 and the connecting member 121, the pull ring 131 can pull the cleaning tank 12 towards the bottom of the housing 1. Simultaneously, the rotation of the drive member 13 will drive the positioning member 14, which is connected to it, to move, causing the positioning member 14 to rotate towards the outer wall of the cleaning tank 12 until the positioning member 14 abuts against the outer wall of the cleaning tank 12. This makes the bottom of the cleaning tank 12 fit tightly against the ultrasonic transducer 11, and the vibration of the ultrasonic transducer 11 is efficiently transmitted to the liquid in the cleaning tank 12 through this contact surface, generating a cavitation effect. When it is necessary to clean the cleaning tank 12, by rotating the drive member 13 in the opposite direction, the pull ring 131 will separate from the connecting member 121, and the positioning member 14 will disengage from the cleaning tank 12, thereby realizing the quick disassembly of the cleaning tank 12.

[0027] The cleaning tank 12 is in close contact with the ultrasonic transducer 11 under the constraint of the pull ring 131 and the positioning member 14, ensuring efficient transmission of vibration energy to achieve the cleaning function. When cleaning is required, the reverse rotation of the drive member 13 can simultaneously release the constraint of the pull ring 131 and the positioning member 14 of the cleaning tank 12, allowing it to be quickly and easily removed directly from the housing 1. This detachable design solves the problem of inconvenient cleaning caused by the fixed connection of the cleaning tank 12 in traditional cleaning machines from the structural root. Users can completely detach the cleaning tank 12 from the housing 1 without the need for tools or complicated operations, and directly wipe, rinse or soak its inner wall, bottom and corners from all directions, thoroughly removing dirt, residue and microorganisms that have accumulated after long-term use, avoiding the risk of secondary pollution caused by the inability to deeply clean traditional fixed structures.

[0028] like Figures 1 to 8 As shown: A transmission component 142 that can slide in the horizontal direction is provided on the side wall of the housing 1, and a sliding groove 132 extending in the vertical direction is provided at the bottom of the driving component 13. One end of the transmission component 142 is slidably engaged with the sliding groove 132. A connecting rod 141 that is hinged to the middle of the positioning component 14 is provided therewith. The connecting rod 141 is hinged to the other end of the transmission component 142.

[0029] In use, rotating the drive member 13 causes it to rotate around its pivot. The slide groove 132 at the bottom of the drive member 13 then moves along a trajectory. The transmission member 142, which slides in cooperation with the slide groove 132, converts the rotation of the drive member 13 into a horizontal linear slide under the guidance of the slide groove 132. The other end of the transmission member 142 pulls the positioning member 14 through the hinged connecting rod 141, causing the positioning member 14 to swing around its connection point with the housing 1. When the drive member 13 rotates in the locking direction, the transmission member 142 slides horizontally and pushes the positioning member 14 towards the outer wall of the cleaning tank 12 through the connecting rod 141 until the end of the positioning member 14 is in close contact with the side wall of the cleaning tank 12. At the same time, the pull ring 131 on the drive member 13 cooperates with the connecting member 121 on the cleaning tank 12, pulling the cleaning tank 12 vertically until the bottom of the cleaning tank 12 is in contact with the ultrasonic transducer 11. This achieves the simultaneous completion of the pulling and lateral positioning of the cleaning tank 12 by the drive member 13.

[0030] When the cleaning tank 12 needs to be disassembled, the drive component 13 is rotated in the opposite direction. The slide groove 132 drives the transmission component 142 to slide horizontally in the opposite direction. The connecting rod 141 pulls the positioning component 14 to swing away from the side wall of the cleaning tank 12, releasing the lateral abutment force. At the same time, the pull ring 131 separates from the connecting component 121, and the constraint force on the cleaning tank 12 disappears synchronously, allowing it to be directly removed from the housing 1. In this way, the rotation of the drive component 13 is transformed into a multi-dimensional positioning action, ensuring that the cleaning tank 12 remains stable during operation through the lateral abutment of the positioning component 14, avoiding displacement or loosening caused by high-frequency vibration. During cleaning, all constraints can be released simultaneously without step-by-step operation, making the disassembly process of the cleaning tank 12 more convenient and efficient. The swinging contact of the positioning component 14 provides reliable support for the working state of the cleaning tank 12, while the sliding cooperation between the transmission component 142 and the slide groove 132 ensures that this support can be quickly and thoroughly released when needed, allowing users to thoroughly clean the inner wall of the disassembled cleaning tank 12, thus eliminating the pain point of traditional fixed connection cleaning tank 12 being difficult to clean deeply from a structural perspective.

[0031] like Figures 1 to 9 As shown: a rotatable roller 143 is provided at the end of the positioning member 14 away from the housing 1, and a groove 122 matching the roller 143 is provided on the outer wall of the cleaning pool 12 at the position corresponding to the roller 143.

[0032] When the driving member 13 drives the positioning member 14, which is connected to it for transmission, to rotate, the roller 143 at the end of the positioning member 14 first contacts the outer wall of the cleaning tank 12 and rolls along the outer wall surface to the groove 122. As the positioning member 14 swings further, the roller 143 is embedded in the groove 122, forming a locking position, so that the circumferential surface of the roller 143 is in contact with the inner wall of the groove 122, restricting the horizontal displacement of the cleaning tank 12; at the same time, the driving member 13 pulls the cleaning tank 12 vertically toward the bottom of the housing 1 through the pull ring 131, so that the bottom of the cleaning tank 12 is in close contact with the ultrasonic transducer 11. During disassembly, the positioning member 14 swings in the opposite direction, and the roller 143 is disengaged from the groove 122 and rolls away along the outer wall of the cleaning tank 12. The entire process uses the rolling friction of the roller 143 to replace the traditional rigid contact sliding friction, reducing the operating resistance. The mechanical wear during the positioning process is significantly reduced, extending the service life of the positioning component 14 and the cleaning tank 12. The groove 122 provides a clear positioning guide for the roller 143, ensuring that the cleaning tank 12 can be quickly and accurately aligned with the ultrasonic transducer 11 during installation, thus improving the stability of vibration transmission. During disassembly, the rolling characteristics of the roller 143 make the separation process between the positioning component 14 and the cleaning tank 12 smoother and less strenuous, avoiding jamming caused by excessive frictional resistance, and further enhancing the ease of disassembly of the cleaning tank 12.

[0033] like Figures 1 to 7 As shown: Both sides of the top of the housing 1 are provided with clearance grooves 15 for avoiding the connector 121.

[0034] When installing the cleaning tank 12, it is inserted from the top of the housing 1. The connector 121 on the cleaning tank 12 is aligned with the clearance grooves 15 on both sides of the top of the housing 1, and moves downward into the housing 1 along the guide path of the clearance grooves 15. The clearance grooves 15 provide an unobstructed movement channel for the connector 121, avoiding interference and collision between the connector 121 and the top of the housing 1. This ensures that the connector 121 can smoothly enter and exit the housing 1 during installation or disassembly of the cleaning tank 12, completely eliminating the installation difficulties or component collision problems caused by obstruction from the top of the housing 1 in traditional structures. This makes the installation and disassembly of the cleaning tank 12 more convenient and efficient, and by avoiding mechanical interference, it reduces the risk of wear between the connector 121 and the housing 1, extending the service life of the equipment.

[0035] like Figures 2 to 5 , Figure 7 and Figure 9 As shown: The bottom of the cleaning tank 12 is provided with a connection groove 123 that matches the ultrasonic transducer 11.

[0036] When the cleaning tank 12 is pulled towards the bottom of the housing 1 by the drive component 13 via the pull ring 131, the connecting groove 123 at the bottom of the cleaning tank 12 will nest and fit with the ultrasonic transducer 11. At this time, the top surface of the ultrasonic transducer 11 is in close contact with the bottom surface of the connecting groove 123. The high-frequency vibration generated by the transducer is directly transmitted to the cleaning tank 12 through this contact surface, driving the liquid in the cleaning tank 12 to generate a cavitation effect. The setting of the connecting groove 123 provides radial constraint to the ultrasonic transducer 11, preventing the cleaning tank 12 from undergoing horizontal displacement or shaking during high-frequency vibration, ensuring that the transducer and the cleaning tank 12 always maintain the optimal energy transfer state. This nested structure also increases the contact area between the cleaning tank 12 and the ultrasonic transducer 11, reduces energy loss during vibration transmission, and allows ultrasonic energy to act more efficiently on the cleaning fluid, improving the intensity and uniformity of the cavitation effect, thereby improving the cleaning effect.

[0037] like Figures 1 to 4 , Figure 6 and Figure 7 and Figure 9 As shown: The top of the housing 1 is provided with a receiving platform 16 extending along its contour, and a guide post 161 is fixedly provided on the receiving platform 16; the top of the cleaning tank 12 is provided with an extension edge 124 matching the receiving platform 16, and a guide hole 1241 adapted to the guide post 161 is provided on the extension edge 124.

[0038] When installing the cleaning tank 12, place the extended edge 124 of the cleaning tank 12 onto the receiving platform 16 at the top of the housing 1, aligning the guide hole 1241 on the extended edge 124 with the guide post 161 on the receiving platform 16. Then, push the cleaning tank 12 downwards into the housing 1 along the axial direction of the guide post 161. The cooperation between the guide post 161 and the guide hole 1241 provides precise vertical guidance for the installation of the cleaning tank 12, ensuring that the cleaning tank 12 will not shift horizontally during descent. After the drive component 13 rotates and drives the pull ring 131 and the positioning component 14 to complete the fixing, the extended edge 124 is completely in contact with the receiving platform 16, forming a top support for the cleaning tank 12. This disperses the weight of the cleaning tank 12 and the stress during vibration, reduces the load on the drive component 13 and the positioning component 14, and extends the service life of the mechanical components. At the same time, this guiding and positioning mechanism effectively suppresses the shaking or tilting of the cleaning tank 12 during disassembly and assembly, reduces the risk of component collision and wear, and makes the maintenance process of the equipment safer and smoother.

[0039] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
