[0034] In this embodiment, the collection box 103 is designed to be installed at the bottom of the installation shell 101 to collect dust and debris generated during cleaning. Two sets of cleaning brushes 102 are installed on one side of the installation shell 101 in a rotating manner, and their main function is to sweep the dust and fine particles on the ground to the center. The roller brush 104 is located on one side of the two sets of cleaning brushes 102 to further help push the accumulated dirt into the collection box 103.

[0035] In order to enhance the dust removal effect, the device is also equipped with a negative pressure pump 105, which can generate sufficient suction to help inhale finer dust particles. It is matched with two first air inlets 106 and a second air inlet 107. The design of these air inlets allows air to flow in from different directions, ensuring the effective collection of dust. In particular, a first baffle 108 is installed at the air inlet of each first air inlet 106. The function of this baffle is to prevent large particles from directly entering the air duct, thereby protecting the internal structure from damage. A sliding first scraper 109 is provided on one side adjacent to the first baffle 108. Through the control of the driver 110, the first scraper 109 can move along a predetermined path, effectively remove the dust accumulated on the baffle, and keep the air inlet unobstructed.

[0036] In addition, the second baffle 111 is arranged at the entrance of the second air inlet 107. This design helps to optimize the airflow direction and ensure the maximum working efficiency of the negative pressure pump 105. Overall, this self-cleaning dust removal device integrates multiple functional components, which not only improves the automation of cleaning work, but also greatly enhances the self-maintenance ability of the equipment, reducing the user's maintenance cost and difficulty of use.

[0038] The dust collecting bucket 112 is connected to the negative pressure pump 105, forming a complete airflow channel from the ground to the dust collecting bucket 112, ensuring that fine particles such as dust can be effectively sucked in and stored. The filter element 113 is installed inside the dust collecting bucket 112, as a key filtering component, responsible for intercepting tiny particles in the air and preventing them from returning to the environment, thereby achieving the purpose of purifying the air.

[0039] The filter element 113 includes a filter element body 114 , a support frame 115 and a handle 116 . The support frame 115 is disposed in the dust collecting barrel 112 , the filter element body 114 is fixed on the support frame 115 , and the handle 116 is disposed on the support frame 115 .

[0040] The support frame 115 is fixed inside the dust collection bucket 112, providing a stable support for the filter element body 114. The filter element body 114 is tightly mounted on the support frame 115, ensuring good sealing and filtering effect. At the same time, in order to facilitate the user to replace or clean the filter element 113, the designer cleverly adds a handle 116 on the support frame 115, making the operation easier and faster.

[0041] The first scraper blade 109 includes a scraper blade body 117, a first spring 118 and a contact brush 119.

The support rod 124 is slidably arranged on one side of the contact rod 123, and is supported by the support spring 125 to ensure that the support rod 124 can be close to the contact rod 123, and then transmit power to the first scraper 109, so that it can slide along a predetermined track, effectively cleaning the dust accumulated on the first baffle 108, when it moves to the extreme position of the first scraper 109, the contact rod 123 will push the support rod 124 to slide, so that the support rod 124 compresses the support spring 125, so that the contact rod 123 can rotate to break away from the contact with the first scraper 109, at this time the first scraper 109 can be reset, and then the cycle can be repeated.

[0047] The driver 110 further includes a protective cover 126 , and the protective cover 126 is used to protect the first gear 121 and the second gear 122 .

[0048] The protective cover 126 covers the first gear 121 and the second gear 122, which can not only prevent dust and debris from entering, but also reduce mechanical wear and extend the service life.

[0049] The second baffle 111 includes a second baffle body 127 and a vibrator 128 . The second baffle body 127 is slidably disposed on one side of the second air inlet duct 107 , and the vibrator 128 is disposed on one side of the second baffle body 127 .

[0050] The second baffle body 127 can slide along one side of the second air inlet 107, which allows it to flexibly adjust its position to meet different cleaning requirements. The vibrator 128 is installed on one side of the second baffle body 127 to help remove dust on the baffle by generating vibration.

[0051] The vibrator 128 includes a cam 129 , a compression spring 130 and a vibration motor 131 .

[0052] The cam 129 is mounted on one side of the second baffle body 127, and the output end of the vibration motor 131 is connected to the cam 129. When the motor is started, the rotation of the cam 129 generates periodic vibrations, which are transmitted to the second baffle body 127 through the compression spring 130, thereby achieving the effect of removing dust. The design of the compression spring 130 ensures the efficiency and stability of vibration transmission.

[0053] The second baffle 111 also includes a moving block 132, a third gear 133, a rack 134, a moving motor 135 and a sweeping brush 136.

When the motor is working, the third gear 133 and the rack 134 can cooperate to drive the moving block 132 to move along the preset track. The sweeping brush 136 is fixed on the moving block 132. As the moving block 132 moves, the sweeping brush 136 can clean the second baffle body 127 more thoroughly. Such a design not only improves the cleaning efficiency, but also ensures the long-term cleaning of the second baffle 111 area, reduces the maintenance frequency, and improves the user experience.

[0055] Second embodiment

[0056] The present invention also provides a self-cleaning dust-removing vehicle, comprising the self-cleaning dust-removing device.

[0057] The present invention also provides a self-cleaning dust removal vehicle, which integrates the self-cleaning dust removal device described above, and is intended to provide efficient and intelligent cleaning solutions for urban streets, industrial parks, large public places, etc.

[0058] Third embodiment

[0059] See also Fig. 9 The present invention also provides a self-cleaning dust removal method, comprising:

[0060] S301 starts two cleaning brushes 102 to clean the ground and collect the cleaned garbage in the center;

[0061] Before starting the cleaning operation, first start the two cleaning brushes 102 installed on both sides of the self-cleaning dust removal vehicle. The two cleaning brushes 102 rotate to sweep the dust, paper scraps, leaves and other debris on the ground to the central area of ​​the vehicle. The design of the cleaning brushes 102 is usually inclined at a certain angle to ensure that the debris can be smoothly gathered in the middle.

[0062] The rotation speed and direction of the cleaning brush 102 can be adjusted according to the ground conditions and cleaning requirements to achieve the best cleaning effect.

[0063] S302 The roller brush 104 drives the garbage into the collection box 103;

[0064] When the debris is collected in the center of the vehicle by the cleaning brush 102, the roller brush 104 on one side of the cleaning brush 102 starts to work. The roller brush 104 further pushes the debris collected in the central area into the collection box 103 by rotating at high speed.

[0065] The design of the roller brush 104 usually has a strong friction force, which can effectively handle various types of garbage and ensure that the debris smoothly enters the collection box 103. At the same time, the rotation direction and speed of the roller brush 104 can also be adjusted according to actual conditions to improve cleaning efficiency.

[0066] S303: starting the negative pressure pump 105 so that negative pressure can be generated in the first air inlet duct 106 and the second air inlet duct 107, and dust generated by cleaning by the cleaning brush 102 is collected through the first air inlet duct 106 and the second air inlet duct 107;

[0067] In order to capture the fine dust and particles generated during the cleaning process, the negative pressure pump 105 is started. The negative pressure pump 105 generates a strong negative pressure in the first air inlet 106 and the second air inlet 107 to form an effective air flow channel.

[0068] These airflow channels suck in the dust and fine particles raised by the cleaning brush 102 and the roller brush 104 during operation, and transmit them to the dust collection bucket 112 through the air inlet duct. The design of the first air inlet duct 106 and the second air inlet duct 107 takes into account the optimization of airflow, ensures efficient collection of dust, and avoids secondary pollution.

[0069] S304 starts the driver 110 to drive the first scraper 109 to move to clean the impurities on the first baffle 108 .

[0070] In order to keep the air inlet duct unblocked, the driver 110 is started to drive the first scraper 109 to move along a predetermined track. The first scraper 109 is close to the first baffle 108 and removes dust and impurities on the baffle through sliding motion.

[0071] The first scraper 109 is generally designed to include a scraper body 117, a first spring 118, and a contact brush 119. The first spring 118 ensures that the scraper body 117 is always in close contact with the baffle, and the contact brush 119 further removes the residue on the baffle. This ensures that the air inlet is always unobstructed and the negative pressure pump 105 is maintained in the best working state.

[0072] The motion of the driver 110 is controlled by a motor to ensure that the scraper blade moves smoothly and efficiently. Meanwhile, the design of the protective cover 126 can protect the key components of the driver 110 and extend its service life.

[0073] Through the above steps, the self-cleaning dust removal method can not only clean the floor efficiently, but also automatically process and collect the dust and debris generated during the cleaning process, greatly reducing manual intervention and improving the automation level and overall efficiency of cleaning operations.

[0074] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
