Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a corrugated pipe assembly for a floor scrubber and a floor scrubber. Background Technology

[0002] As people have higher and higher requirements for home cleaning, smart cleaning tools such as home floor scrubbers are becoming more and more popular. Most floor scrubbers on the market can now clean dry and wet garbage on the floor. They use a fan to suck the dirt into a corrugated pipe and then send it to a wastewater tank.

[0003] Currently, the corrugated pipes and connectors of floor scrubbers on the market are fitted using two methods: curved surface adhesive and spiral adhesive. Curved surface adhesive uses a smooth surface at the corrugated pipe connection, with the corrugated pipe inserted directly into the connector and wastewater outlet. This method results in poor adhesion and a tendency for the pipe to detach. Spiral adhesive uses a threaded connection between the corrugated pipe and the connector. Adhesive is applied to the threaded groove before the connector is screwed in. This method is more stable but less efficient. Furthermore, both of these adhesive methods require extensive disassembly for replacement after the corrugated pipe assembly is installed in the machine. Additionally, the connectors cannot be easily replaced due to the adhesive, leading to high maintenance costs and low efficiency. Summary of the Invention

[0026] The corrugated pipe joint 11 is provided with a connecting block, and the connecting block is provided with a slot along its circumference. The slot is connected to the slot at the lower end of the sewage tank 62. The slot is provided with a threaded structure, and the slot is provided with a threaded slot structure that is compatible with the slot.

[0027] The end of the corrugated pipe joint 11 that connects to the sewage tank 62 is provided with a silicone part to form a sealed connection with the sewage tank 62.

[0028] The sewage outlet connector 12 is symmetrically provided with a crossbar 121 and a top rod protrusion 122, with the top rod protrusion 122 located on the crossbar 121.

[0029] A push rod element 4 is provided on the push rod protrusion 122, and the driving end of the push rod element 4 faces the push rod protrusion 122.

[0030] Two component grooves are provided. The component groove 13 is located on the lower side of the connecting block. The component groove 13 is also symmetrically arranged on the circumference of the bellows 1. The plane of the inner wall of the component groove 13 is set as a transparent plane.

[0031] The wastewater detection unit 2 is equipped with an infrared emitting element and an infrared receiving element. The emitting end of the infrared emitting element faces the transparent plane inside the element groove 13, and the infrared receiving element is located on the opposite side of the infrared emitting element. The receiving end of the infrared receiving element faces the transparent plane inside the other element groove 13.

[0032] As another technical solution of the present invention: a floor scrubber, including the above-mentioned easily detachable corrugated pipe 1 connection structure, and also including a body 6 and a floor brush base 7. The body 6 is provided with a clean water tank 61, a wastewater tank 62 and a power component. The lower end of the wastewater tank 62 is provided with a slot. The floor brush base 7 includes a wastewater outlet 5 and a floor brush water pump. The body 6 is also provided with a handle 64. The handle 64 has a disassembly button 65. The wastewater outlet 5 is provided with a through hole adapted to the top rod protrusion 122. The floor brush base 7 is equipped with a top rod element 4.

[0033] Implementation Case 1:

[0034] This invention relates to a corrugated pipe 1 connection structure and a floor scrubber that can be easily disassembled and assembled. The aim is to achieve the disassembly and assembly of the corrugated pipe 1 and the arbitrary switching of the floor scrubber's operating states without requiring significant disassembly and assembly of the scrubber. For ease of description, a specific embodiment is provided for illustration. It should be emphasized that the described embodiment is only a part of this application.

[0035] The connection structure of the easily detachable corrugated pipe 1 is illustrated with the attached diagram as an example, as detailed below:

[0036] The corrugated pipe 1 has different connecting structures at both ends to facilitate easy assembly and disassembly with the structure of the machine body 6. These are the corrugated pipe connector 11 and the sewage outlet connector 12. The corrugated pipe 1 serves as a channel for sewage to enter the sewage tank 62 inside the machine body 6, while also ensuring a tight seal during sewage flow. The corrugated pipe 1 and the two connectors are made through secondary injection molding, resulting in a robust and highly airtight assembly.

[0037] The corrugated pipe joint 11 has a slot on its circumference, which can be configured as a threaded structure. The corrugated pipe joint 11 is threadedly connected to the slot at the lower end of the sewage tank 62. In order to prevent the corrugated pipe joint 11 from falling off the slot at the lower end of the sewage tank 62 and to ensure sealing, an annular silicone part is provided at the upper port of the corrugated pipe joint 11 after flaring.

[0038] The sewage outlet connector 12 is provided with a crossbar 121 and a top rod protrusion 122. The crossbar 121 and the top rod protrusion 122 form a snap-fit ​​structure that engages with the through hole at the sewage outlet 5, so that the sewage outlet connector 12 is fastened to the sewage outlet 5, and the corrugated pipe 1 can be fastened to the sewage outlet 5. The crossbar 121 is made of elastic material. When the top rod protrusion 122 is pushed out, the crossbar 121 is recessed inward so that it can be pushed out, thereby realizing the disassembly function of the corrugated pipe 1.

[0039] The wastewater detection unit 2 includes an infrared emitting element and an infrared receiving element, both of which are installed in a fixed position inside the body 6 of the floor scrubber. The infrared emitting element and the infrared receiving element are arranged opposite to each other so that the infrared light emitted by the infrared emitting element can be received by the infrared receiving element.

[0040] The element groove 13 is located on the circumference of the connection between the corrugated pipe 1 and the corrugated pipe joint 11. It is a groove that is recessed into the corrugated pipe 1, and its bottom plane is made of a light-transmitting material. Its bottom plane is a transparent plane. When the corrugated pipe joint 11 is screwed and fixed in the slot at the lower end of the sewage tank 62, the transparent plane of the inner wall of the element groove 13 will allow the infrared emitting element and the infrared receiving element of the sewage detection unit 2 to penetrate the corrugated pipe joint 11 and be received by the infrared receiving element, so as to detect the sewage dirt intensity in real time when sewage enters the sewage tank 62 through the corrugated pipe 1.

[0041] A conveniently detachable corrugated pipe 1 connection structure and floor scrubber include a machine body 6 and a floor brush base 7. One end of the corrugated pipe 1 is connected and locked into a slot at the lower end of the wastewater tank 62 of the machine body 6 via a corrugated pipe connector 11. The other end is connected and locked into a wastewater outlet 5 in the floor brush base 7 via a wastewater outlet connector 12. One end of the wastewater outlet connector 12 is equipped with a flexible snap-fit ​​structure, which allows for controlled assembly and disassembly of one end of the wastewater outlet connector 12. This enables quick replacement and cleaning of the corrugated pipe 1 assembly, achieving the function of cleaning and disassembling the corrugated pipe 1 without extensive disassembly of the floor scrubber. Even if it breaks, the components can be quickly replaced to maintain the function of continuous operation and avoid the need to return to the factory for repair. At the same time, it provides a dirt intensity detection function, which can identify the dirt intensity of the environment in real time and adjust the enhanced function accordingly to clean the floor. Correspondingly, the clean water tank 61, wastewater tank 62, power component and the floor brush base 7 are set with floor brush water pump, wastewater outlet 5 and push rod element 4. The power component is a blower 63. A disassembly button 65 is set on the handle 64 of the machine body 6. The disassembly button 65 can control the push rod element 4 to push forward and push the push rod protrusion 122 out of the through hole.

[0042] Floor scrubber operating status (fan 63 operating normally, i.e., the floor scrubber circulates water at a constant speed through each channel): The floor scrubber starts normally. At this time, the floor brush water pump pumps clean water from the clean water tank 61 at a constant speed for washing. At the same time, the fan 63 starts normally, and sewage is drawn in from the sewage outlet 5. The sewage flows through the corrugated pipe 1, thus allowing the sewage to enter the sewage tank 62. Simultaneously, the sewage detection unit 2 transmits and receives normally, i.e., the infrared light emitted by the infrared emitting element can be received by the infrared receiving element. When the sewage detection unit 2 transmits and receives normally, the detected sewage dirt intensity is normal, i.e., the environment is relatively dirty.

[0043] In the high-power operation mode of the floor scrubber (high-power mode of blower 63, i.e., the floor scrubber increases the flow of water through all channels): When sewage is sucked in from sewage outlet 5 and flows through corrugated pipe 1, the sewage detection unit 2 experiences a transmission and reception abnormality. That is, the infrared light emitted by the infrared emitting element cannot be received by the infrared receiving element. When the sewage detection unit 2 experiences a transmission and reception abnormality, the detected sewage dirt intensity is high, i.e., the environment is heavily dirty. The infrared light passing through the corrugated pipe 1 will be blocked by too much dirt and become weak, thus failing to be received, triggering the high-power operation mode. The suction power of blower 63 will increase, and at the same time, the water output of the floor scrubber pump will increase, cleaning the heavily polluted floor.

[0044] Corrugated pipe 1 replacement status (corrugated pipe 1 is broken or emits an odor, and corrugated pipe 1 needs to be replaced): Press and hold the disassembly button 65 at the handle 64. Pressing and holding can prevent accidental touch and at the same time realize the disassembly function of corrugated pipe 1. At this time, the blower 63 starts at maximum power to suck away the dirt and water that can be sucked away in each channel. Then, the push rod elements 4 at both ends of the sewage outlet 5 are activated to push the push rod protrusion 122 of the sewage outlet connector 12 out of the through hole. The sewage outlet connector 12 of corrugated pipe 1 is in a detachable state. This realizes the function of cleaning and disassembling corrugated pipe 1 without extensive disassembly of the machine. At the same time, corrugated pipe 1 can be completely replaced by replacing the same part.

[0045] The floor scrubber is equipped with a system that enables the above operations, allowing the floor scrubber to assemble and disassemble the corrugated pipe 1 and switch between various working states.

[0046] Example 2:

[0047] A floor scrubber includes the aforementioned easily detachable corrugated pipe 1 connection structure, and also includes a body 6, a floor brush base 7, and a system. The body 6 is provided with a clean water tank 61, a wastewater tank 62, and a power component. The lower end of the wastewater tank 62 is provided with a slot. The floor brush base 7 includes a wastewater outlet 5 and a floor brush water pump. The body 6 is also provided with a handle 64, which has a disassembly button 65. The wastewater outlet 5 is provided with a through hole that matches the top rod protrusion 122. The floor brush base 7 is equipped with a top rod element 4.

[0048] The corrugated pipe 1 connection structure consists of corrugated pipe 1, wastewater detection element, corrugated pipe connector 11, wastewater outlet connector 12, wastewater outlet 5, and top rod element 4. The corrugated pipe 1 and the two connectors are connected by secondary injection molding, resulting in high component strength and airtightness. When assembled on the floor scrubber, the top rod element 4 is in a retracted state, and its top rod does not contact the protrusion. After cooperating with the wastewater outlet 5, the two sealing rings set on the wastewater outlet 5 will form a double seal, enhancing the airtightness of the entire machine. Dirt is sucked in from the wastewater outlet 5 and sent to the wastewater tank 62 along the corrugated pipe 1. When passing through the lower end of the corrugated pipe connector 11, the infrared light emitted by the wastewater detection unit 2 will pass through the corrugated pipe 1. The intensity of the light is used to detect the level of dirt in the working environment. If there is a lot of dirt in the environment, the infrared light passing through the corrugated pipe 1 will be blocked by too much dirt and become weak, thereby triggering the system's strong mode. In this mode, the suction of the fan 63 will increase, and the water output of the floor brush pump will increase, realizing the dirt detection function. After the floor scrubber has been working for a period of time, dirt will accumulate in the corrugated grooves on the inner wall of the corrugated pipe 1, mold will grow, and it may even emit a strong odor. At this time, the corrugated pipe 1 needs to be cleaned. Press the corrugated pipe 1 disassembly function button on the handle 64. The fan 63 will start at maximum power to suck away the dirt and water in the channel. Then, the push rod elements 4 at both ends of the sewage outlet 5 will start to hold the buckle of the sewage outlet connector 12. At this time, the sewage outlet connector 12 is in a detachable state. After separating the sewage outlet 5 from the sewage outlet connector 12, remove the sewage tank. Rotate the corrugated pipe connector 11 until it is completely loose, and then take out the entire corrugated pipe 1 for cleaning. This realizes the function of cleaning and disassembling the corrugated pipe 1 without extensive disassembly of the machine. At the same time, the corrugated pipe 1 can be completely replaced by replacing the same part. This realizes the function of quickly replacing components to continue operation even if the corrugated pipe 1 is broken, avoiding the need for factory repair.

[0049] In summary, after reading this invention document, those skilled in the art can make various other corresponding modifications to the technical solutions and concepts based on this invention without creative mental effort, and all of these modifications fall within the scope of protection of this invention.
