Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure cleaning machines, in particular to a portable cleaning machine. Background Art

[0002] A cleaning machine uses a high-pressure plunger pump powered by a power unit to generate high-pressure water to wash surfaces. It removes dirt and flushes it away, ultimately cleaning the surface. Because it uses high-pressure water jets to remove dirt, high-pressure cleaning is recognized worldwide as one of the most scientific, economical, and environmentally friendly cleaning methods. High-pressure cleaning machines are typically mounted on a wheeled frame that can be moved to different locations, making it easier to clean in different locations.

[0003] However, the cleaning machine under the existing technology is usually placed on the ground, and there may be a situation where the height is insufficient when connecting the power supply and performing cleaning. At this time, it is very inconvenient to perform cleaning, and in some cases, cleaning work cannot be performed. Summary of the Invention

[0004] In order to solve the problem that cleaning machines in the prior art are usually placed on the ground and may not be at a high enough height when connecting to the power supply and performing cleaning, which makes cleaning very inconvenient and even impossible in some situations, the present application provides a portable cleaning machine.

[0005] A portable cleaning machine comprises a body and a frame, the body being used for pressurized water, the frame being provided with movable wheels at the bottom thereof, the movable wheels being rotatably connected to the frame, the body being detachably connected to the frame, the body being provided with an input port and an output port, the input port being used for introducing a water source, the output port being used for discharging pressurized water, the body being further provided with a handle, the handle being fixedly connected to the body; A fixing frame is provided on the machine body corresponding to the frame body, a supporting rod is provided on the frame body corresponding to the fixing frame, and a supporting plate is provided on the supporting rod corresponding to the fixing frame, and the supporting plate can abut against the fixing frame; The supporting plate is arranged at both ends of the fixing frame, and a locking column is slidably connected to the fixing frame. A locking groove is opened on the supporting plate corresponding to the locking column. The locking column is arranged at the position corresponding to the locking groove and can extend into the locking groove.

[0006] By adopting the technical scheme, the portable cleaning machine not only has a basic high-pressure water cleaning function, but also can be conveniently moved at different locations through the design of the moving wheels and the handle, and the body of the cleaning machine can be dismounted to work at different heights. In addition, the cooperation of the fixing frame, the supporting rod and the supporting plate ensures the stability of the body on the frame body, effectively preventing the shaking and falling risk during transportation. The setting of the locking column and the locking groove further enhances the reliability of the fixation, ensuring the stability and safety of the cleaning machine in the working state.

[0007] Optionally, the fixing frame is provided with a locking column at each end, and a locking groove is formed in the supporting plate at each end of the fixing frame.

[0008] By adopting the technical scheme, the connection between the body and the frame body is more stable and reliable, avoiding the risk of body falling due to vibration during movement. At the same time, the design of the double locking columns improves the locking force, ensuring that the device can maintain a good fixed state in various use environments, enhancing the overall stability and safety of the device.

[0009] Optionally, a drive gear is arranged between the two locking columns, and a transmission rack is arranged on each of the two locking columns and engaged with the drive gear on both sides. A sliding block is further arranged on the fixing frame and is in sliding connection with the fixing frame. A drive rack is fixedly arranged on the sliding block and is also engaged with the drive gear. The drive gear can drive the locking columns to move towards each other or away from each other.

[0010] By adopting the technical scheme, the locking columns can move towards each other or away from each other synchronously under the action of the drive gear. This design not only improves the operation convenience of the locking mechanism, but also ensures the stability and reliability of the locking process. When locking is needed, the drive gear drives the two locking columns to move inward at the same time, quickly completing the locking action. When unlocking is needed, reverse operation can make the locking columns quickly separate, facilitating disassembly, assembly and maintenance of the user. In addition, this design can effectively prevent safety hazards caused by failure of a single locking column, improving the use safety of the entire cleaning machine.

[0011] Optionally, a return spring is further arranged in the fixing frame, one end of the return spring is fixedly connected with the clamping block, and the other end of the return spring is fixedly connected with the sliding block. The return spring has a tendency to push the sliding block to drive the locking columns to move away from each other.

[0012] By adopting this technical solution, the reset spring allows the locking column to automatically return to its initial position when no external force is applied, thus eliminating tedious manual operation and improving ease of use. Furthermore, the elastic recovery characteristics of the reset spring ensure the stability of the locking column in the unlocked state, reducing the risk of locking failure due to accidental collisions, and improving the safety and reliability of the device.

[0013] Optionally, a feed groove is provided on the support plate corresponding to the locking column, the feed groove is connected to the locking groove, and a guide arc surface is provided on the end of the locking column away from the other locking column, and the guide arc surface can abut the support plate at the top position of the feed groove.

[0014] By adopting this technical solution, a feed slot can be provided on the support plate, and a guide arc surface can be provided at the end of the locking post. This allows the locking post to smoothly and automatically enter the locking slot without the need to move the sliding block for installation, thereby achieving rapid positioning and stable connection between the body and the frame. The guide arc design effectively avoids the possibility of jamming during the locking process, improving user convenience and device stability.

[0015] Optionally, a push rod is further provided on the frame, which is fixedly connected to the frame and used to hold and push the frame to move. A lifting frame is provided on the upper side of the push rod, which is fixedly connected to the push rod and also has a support plate with the same structure.

[0016] By adopting the above technical solution, a push rod and a lifting frame are added to the frame. The push rod is convenient for users to grasp and push the frame to move, improving the portability and ease of operation of the equipment. The lifting frame design allows the cleaning machine to be placed on it, thereby increasing the height, solving the problem of insufficient height in the existing technology that makes cleaning impossible. A support plate with the same structure is also provided to ensure the stability and safety of the machine body in the raised state.

[0017] Optionally, a telescopic rod is further provided between the machine body and the frame body, the bottom of the telescopic rod is hinged to the frame body, and the top of the telescopic rod is hinged to the machine body and is detachably connected, and the lifting frame is set to correspond to the shape of the machine body.

[0018] By adopting the above technical solution, the design of the telescopic rod allows the height of the machine to be flexibly adjusted to suit different cleaning scenarios. When the height of the cleaning machine needs to be raised, this can be achieved by adjusting the length of the telescopic rod, avoiding the impact of insufficient height on the cleaning effect. Furthermore, the detachable connection design of the telescopic rod facilitates removal when the entire machine needs to be disassembled, further improving the portability and ease of operation of the device. The provision of the lifting frame not only increases the operating comfort of the push rod, but also ensures the stability of the machine in the raised state, preventing it from tipping over during use.

[0019] Optionally, a support rod is provided on the lifting frame corresponding to the telescopic rod, and a matching groove is provided on the support rod corresponding to the telescopic rod. The telescopic rod can be embedded in the matching groove and abut against the groove wall of the matching groove. A vertical rod is also provided at the bottom of the support rod, and the bottom of the vertical rod is fixedly connected to the frame body, and the top of the vertical rod is fixedly connected to the support rod.

[0020] By adopting the above technical solution, this can be achieved by adjusting the length of the telescopic rod. The mating groove on the support rod ensures that the telescopic rod is stably embedded and closely contacted with it, thereby improving the stability of the entire device. At the same time, the provision of the vertical rod further enhances the stability of the support rod. The telescopic rod, support rod and vertical rod can form a triangle together, thereby improving the support effect and stability of the body.

[0021] Optionally, an electromagnet is further provided in the fixing frame, the electromagnet is electrically connected to the body, the electromagnet is arranged corresponding to the position of the sliding block, and the electromagnet can absorb the sliding block to drive the locking column to extend into the locking groove.

[0022] By adopting the above technical solution, the portable cleaning machine can install an electromagnet in the fixed frame and electrically connect it to the body. When the support plate needs to be locked, the electromagnet can be activated through the control circuit, and the magnetic force generated by the electromagnet is used to attract the sliding block, thereby driving the locking column into the locking groove, realizing a quick locking function. It can also lock the position of the body more stably based on the reset spring. This design not only improves the convenience of operation, but also enhances the reliability of the lock, ensuring that it will not loosen during movement. At the same time, the introduction of the electromagnet makes the locking process more automated, reduces the complexity of manual operation, and improves the user experience.

[0023] Optionally, a passage groove is provided on the supporting plate corresponding to the electromagnet, and a conductive sheet is provided in the passage groove, and the conductive sheet can connect the electromagnet with the circuit of the body.

[0024] By adopting the above technical solution and setting a passage groove, when the machine body is inserted into the passage groove and powered on, the electromagnet is started to lock the machine body on the frame, making the machine body more stable during operation, thereby further improving the stability during operation.

[0025] In summary, this application has at least the following beneficial effects: 1. This application solves the problem that in the prior art, cleaning machines are usually placed on the ground, and there may be insufficient height when connecting the power supply and performing cleaning, which makes it very inconvenient to perform cleaning, and in some cases, cleaning cannot be performed. This application connects the machine body and the frame in a detachable manner. When work at different heights is required, the machine body can be directly removed, making the use of the machine body more flexible.

[0026] 2. This application also provides a lifting frame. When there is no suitable place to place the machine body in the workplace, the product can be placed on the lifting frame to work. It can provide a place to place the machine body, thereby achieving the lifting of the product. At the same time, a triangle can be formed during the lifting process for support, thereby ensuring stability during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0034] Example 1 A portable cleaning machine, such as Figure 1As shown, the body 1 includes a frame 2 and a housing 2. The body 1 is used for pressurized water. The bottom of the frame 2 is provided with a moving wheel 21, which is rotatably connected to the frame 2. The body 1 is detachably connected to the frame 2. The body 1 is provided with an input port 11 and an output port 12. The input port 11 is used to introduce water, and the output port 12 is used to discharge pressurized water. The body 1 is also provided with a handle 13, which is fixedly connected to the body 1. In specific implementation, the body 1 needs to be powered on to work. Water is introduced at the input port 11, and the water is pressurized inside the body 1 and discharged from the output port 12. A water gun for flushing is usually provided, and flushing needs to be done by holding the water gun.

[0035] like Figure 2 and Figure 3 As shown, a fixing bracket 14 is provided on the body 1 corresponding to the frame 2. A supporting rod 22 is provided on the frame 2 corresponding to the fixing bracket 14. A supporting plate 23 is also provided on the supporting rod 22 corresponding to the fixing bracket 14. The supporting plate 23 is capable of abutting the fixing bracket 14. The supporting plates 23 are provided at both ends of the fixing bracket 14. Locking posts 141 are slidably connected to the fixing bracket 14. Locking slots 231 are defined on the supporting plates 23 corresponding to the locking posts 141. The locking posts 141 are positioned corresponding to the locking slots 231 and can be inserted into the locking slots 231. Locking posts 141 are provided at both ends of the fixing bracket 14. Locking slots 231 are also defined on the supporting plates 23 at both ends of the fixing bracket 14. In a specific embodiment, during installation, the locking posts 141 can be inserted into the locking slots 231 for fixation. When disassembly is required, the locking posts 141 can be removed from the locking slots 231 to complete disassembly.

[0036] like Figure 2 and Figure 3 As shown, a drive gear 142 is disposed between the two locking posts 141. Both locking posts 141 are provided with transmission racks, which mesh with the drive gears 142 on either side. A sliding block 144 is also provided on the fixed frame 14. The sliding block 144 is slidably connected to the fixed frame 14. A drive rack 143 is fixedly disposed on the sliding block 144, which also meshes with the drive gear 142. The drive gear 142 can drive the locking posts 141 toward or away from each other. In a specific implementation, pushing the sliding block 144 can cause the drive gear 142 to rotate, which in turn can cause the locking posts 141 to move. Thus, a single sliding block 144 can drive the two sliding posts toward or away from each other.

[0037] like Figure 1 and Figure 3As shown, a return spring 145 is also disposed within the fixing frame 14. One end of the return spring 145 is fixedly connected to the clamping block, and the other end of the return spring 145 is fixedly connected to the sliding block 144. The return spring 145 tends to push the sliding block 144 to drive the locking post 141 away from each other. In a specific implementation, the return spring 145 can push the locking post 141 to lock it, thereby reducing the possibility of the body 1 loosening after being fixed to the frame 2, thereby reducing the possibility of the body 1 falling off.

[0038] like Figure 2 and Figure 3 As shown, the support plate 23 further defines a feed slot 232 corresponding to the locking post 141. The feed slot 232 communicates with the locking slot 231. A guide arc 146 is provided on one end of the locking post 141 away from the other locking post 141. The guide arc 146 is capable of abutting the support plate 23 at the top of the feed slot 232. In practice, the locking post 141 can be fed into the locking slot 231 without adjusting the sliding block 144. As the locking post 141 is fed, it can move toward the center under the guidance of the guide arc 146. When the locking post 141 is aligned with the locking slot 231, it can be actively released, thereby completing the locking.

[0039] Working principle: By controlling the locking column 141 through the sliding block 144, the body 1 can be quickly disassembled and assembled. When the use environment of the body 1 is different, the body 1 can be disassembled from the frame 2, thereby improving the versatility of the body 1.

[0040] Example 2 like Figure 4 As shown, the main difference between the second embodiment and the first embodiment is that the frame 2 of the second embodiment is further provided with a push rod 24, which is fixedly connected to the frame 2 and is used to grip and push the frame 2 to move. A lifting frame 241 is provided on the upper side of the push rod 24, which is fixedly connected to the push rod 24 and has a supporting plate 23 with the same structure. In specific implementation, when the machine body 1 needs to be lifted but there is no other place to place the machine body 1, the machine body 1 can be placed on the lifting frame 241 for operation, thereby further improving versatility.

[0041] like Figure 4As shown, a telescopic rod 3 is further provided between the body 1 and the frame 2. The bottom of the telescopic rod 3 is hinged to the frame 2, and the top of the telescopic rod 3 is hinged to the body 1 and detachably connected. The lifting frame 241 is configured to correspond to the shape of the body 1. A support rod 242 is further provided on the lifting frame 241 corresponding to the telescopic rod 3. A matching groove 244 is formed on the support rod 242 corresponding to the telescopic rod 3. The telescopic rod 3 can be embedded in the matching groove 244 and abut the groove wall of the matching groove 244. A vertical rod 243 is further provided at the bottom of the support rod 242. The bottom of the vertical rod 243 is fixedly connected to the frame 2, and the top of the vertical rod 243 is fixedly connected to the support rod 242. In specific implementations, the telescopic rod 3 can be used to lift the machine body 1 when it is raised, making it more stable during the lifting process. When the machine body 1 is lifted, it can be moved toward the lifting frame 241. The support rod 242, the vertical rod 243, and the telescopic rod 3 form a triangular structure, making the machine body 1 more stably fixed to the lifting frame 241, thereby improving stability during operation. In other embodiments, a counterweight block can be installed on the frame 2 to reduce the possibility of the machine body 1 tipping over due to uneven weight, further improving stability during use.

[0042] Working principle: The basic working principle is the same as that of embodiment 1, but an elevating frame 241 is added to place the body 1, and is supported by the telescopic rod 3, the support rod 242 and the vertical rod 243. When pushing the frame 2 to move, it can also be pushed by the push rod 24.

[0043] Example 3 like Figure 5 As shown, the main difference between Example 3 and Example 2 is that an electromagnet 147 is further provided within the fixing frame 14. The electromagnet 147 is electrically connected to the housing 1 and is positioned corresponding to the position of the sliding block 144. The electromagnet 147 can attract the sliding block 144 to drive the locking post 141 into the locking slot 231. A passage slot 233 is provided on the support plate 23 corresponding to the electromagnet 147. A conductive sheet 234 is provided within the passage slot 233. The conductive sheet 234 can connect the electromagnet 147 to the circuit of the housing 1. In specific implementation, the electromagnet 147 can only conduct electricity when connected to the conductive sheet 234. The electromagnet 147 can only operate when the housing 1 is in operation. When the electromagnet 147 is in operation, it indicates that the housing 1 is in operation, and the housing 1 will be locked, thereby making the housing 1 more stable during operation and improving operational stability.

[0044] Working principle: The basic working principle is the same as that of embodiment 2, but an electromagnet 147 capable of locking the body 1 is added. The working status of the body 1 is used to determine whether the body 1 needs to be locked, thereby increasing the stability of the body 1 during operation.

[0045] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
