Description

Technical Field

[0001] This invention belongs to the field of tissue dispenser technology, specifically relating to an intelligent tissue dispenser that disinfects, sterilizes, and removes odors. Background Technology

[0002] A smart tissue dispenser is a daily necessity that evenly moistens tissues. It typically consists of two parts: a lower tissue box and an upper mist cube (humidifier). To use it, simply pull a tissue from the tissue box and bring it close to the infrared sensor area of ​​the mist cube. The dispenser will then spray out even mist droplets, uniformly moistening the tissue for wiping. This device avoids the bacterial growth problems that can occur from keeping tissues constantly damp, and also eliminates concerns about preservatives in wet wipes.

[0003] Existing technology discloses a method where the humidification nozzle is detachably mounted on the water outlet pipe. When the nozzle becomes clogged, the user can easily remove it from the water outlet pipe and replace it with a new one to ensure that the paper towels are humidified evenly. However, in actual use, due to the nozzle's design being close to the paper outlet, the liquid cannot be fully absorbed during spraying, causing it to drip downwards, affecting the user experience and floor cleanliness. Furthermore, the direct spraying of liquid results in uneven dispersion, and the liquid remains on the paper towel surface, leading to poor paper towel quality and a poor user experience. Therefore, this paper proposes a smart paper towel dispenser that disinfects, sterilizes, and deodorizes. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an intelligent paper towel dispenser that disinfects, sterilizes, and removes odors.

[0005] The technical solution adopted to solve the above technical problems is:

[0006] A smart tissue dispenser for disinfection, sterilization, and deodorization includes a housing with upper and lower layers. The upper layer of the housing has an upward-opening tissue-holding cavity and a socket. The lower layer of the housing has a device cavity. A tissue feed port is provided between the device cavity and the tissue-holding cavity. A tissue outlet is provided on the bottom side wall of the housing. A control module is located at the front end of the housing.

[0007] A processing assembly installed in the device cavity, the processing assembly forming a conveying channel between the paper feed port and the paper output port, the processing assembly including;

[0008] The paper jam prevention structure located below the paper feed opening includes two hollow rollers and a power unit. The paper is wound between the two hollow rollers, and the power unit drives the hollow rollers to reciprocate closer and further away.

[0009] The paper cutting structure located below the anti-paper jamming structure includes a middle shell, a reversing cavity formed in the middle of the middle shell, a chip collection cavity formed in the middle of the reversing cavity, and a cutter for cutting paper installed in the chip collection cavity.

[0010] The wetting structure located below the paper cutting structure includes a guide shell, a spray frame at the top opening of the guide shell, and two pressure rollers stacked one and the other inside the guide shell. A slit is provided at the bottom of the guide shell.

[0011] The paper conveying structure includes a driving roller and a driven roller that are in squeezing contact. The driving roller and the driven roller are located at the top opening of the reversing cavity. The conveying structure also includes two receiving rollers, which are located at the bottom opening of the reversing cavity and are in squeezing contact with each other. A guide roller is installed between the paper cutting structure and the wetting structure.

[0012] A negative pressure structure that provides a negative pressure environment, wherein the negative pressure structure is connected to the hollow roller and the chip collection cavity respectively through a collecting pipe;

[0013] A water supply bottle is installed in the socket, and the bottom of the water supply bottle has an opening. The water supply bottle is used to provide disinfectant water to the spray frame. A pump is installed between the spray frame and the socket.

[0014] Rolls of dry paper towels are placed individually in the paper receiving cavity, with the paper ends extending through the paper feeder into the processing unit. Disinfectant is separately contained in a water supply bottle. When needed, the trigger control module activates the conveyor structure to feed the paper downwards. The hollow rollers of the anti-jamming structure reciprocate, moving closer and further away to loosen the paper from its wound state, reducing conveying resistance and preventing the paper from being torn by the conveyor structure. At the same time, free debris is drawn out through the hollow rollers. After the paper reaches the length of a single section, the cutter cuts the paper while simultaneously drawing out debris. The paper above the cutter is held by the drive and driven rollers to prevent it from affecting the next paper output, while the paper below the cutter is held by the receiving roller to ensure a clean cut. The cut paper is conveyed into the wetting structure, where disinfectant is sprayed out in the lower section of the conveyor to wet the paper. Pressure rollers one and two squeeze and disperse the disinfectant absorbed in the lower section of the paper to the upper section, resulting in fully wetted paper that does not drip.

[0015] Furthermore, the outer shell includes an inner shell, which is provided with an oblique diameter hole between the anti-jamming structure and the paper cutting structure. The oblique diameter hole is designed to protrude forward in the middle. The active roller is provided with spiral strips at both ends. The spiral strips rotate to spread the paper to the left and right sides.

[0016] With the above technical solution, in order to ensure that the paper is flat in the horizontal direction, when the paper is pulled down through the oblique diameter hole, it will be squeezed and flattened to both sides by the oblique diameter hole. In addition, the rotating spiral will push the two sides of the paper to the left and right respectively, so that it is flattened in the horizontal direction.

[0017] Furthermore, the device cavity has a built-in drive structure, which is equipped with a gear set. The drive structure can drive the drive roller and one of the receiving rollers to rotate through the gear set, and the drive structure can drive the two hollow rollers to rotate through the gear set.

[0018] The above technical solution provides a power source for paper feeding. The drive structure is equipped with a servo motor, which distributes the rotational power to the drive roller and one of the receiving rollers through a gear set. The drive roller pulls the paper above downwards, and the receiving roller clamps the paper below and continues to push it downwards. The rotation of the two hollow rollers can scrape off more free paper scraps, ensuring the cleanliness of the equipment and the quality of the output paper.

[0019] Furthermore, the power component has two components located at the ends of the two hollow rollers. The power component includes a connecting frame and a sliding sleeve. The two connecting frames are rotatably connected to one of the hollow rollers, and the two sliding sleeves are fitted onto the end of the other hollow roller. A spring frame is installed between the connecting frame and the inner shell. A magnetic attractor is installed on the upper part of the connecting frame. An electromagnet is installed on the inner shell directly opposite the position of the magnetic attractor. When the connecting frame is attracted and translated by the electromagnet, it can push the sliding sleeve to move upward.

[0020] Through the above technical solution, in order to achieve the smooth movement of the two hollow rollers away and close together, the connecting frame can be attracted and moved backward by an electromagnet. At this time, the spring frame is stretched and stored. After the electromagnet is de-energized, the spring frame rebounds and causes the connecting frame to move forward and reset. During the forward movement of the connecting frame, the sliding sleeve is pushed upward, causing the two hollow rollers to move away from each other. During the backward movement of the connecting frame, the sliding sleeve moves downward and resets, causing the two hollow rollers to move closer to each other, thus completing the reciprocating drive action.

[0021] Furthermore, a heater is installed at the outlet end of the pump, and the heater is connected in series between the spray frame and the pump via a pipe.

[0022] To improve comfort, the above technical solution allows for the activation of a heater based on ambient temperature when temperatures are low. This heater heats the paper before the disinfectant is sprayed onto it, and the heating temperature can be adjusted via a control module to enhance comfort.

[0023] Furthermore, the outer casing also includes a cover shell, which is fastened and installed above the paper receiving cavity. A sensor is installed on the outer casing at the receiving roller, and a sensor is installed on the outer casing above the pressure roller. A temperature sensor is built into the heater.

[0024] With the above technical solution, the cover opening faces downwards and is directly attached to the paper receiving cavity, making it easy to remove for adding paper rolls. Sensor 1 is used to detect whether the paper has reached the receiving roller position and promptly detect paper jams at the cutter position. Sensor 2 can detect whether the paper has reached the pressure roller position and can serve as the starting signal for disinfectant spraying. The temperature sensor can detect the heating temperature to prevent the disinfectant from overheating or underheating.

[0025] Furthermore, the cutter is arranged horizontally, the sharpened end of the cutter is serrated, a secondary cutter is installed in the chip collection cavity at the top surface of the cutter, a force-bearing frame is installed at the unsharpened end of the cutter, an eccentric shaft is installed on the top of the middle shell to push the force-bearing frame to move laterally, and a reset component is installed between the cutter and the middle shell.

[0026] Through the above technical solution, in order to achieve smooth paper cutting, when not cutting paper, the reset component pulls the cutter backward to ensure the smooth flow of the conveying channel. When cutting paper, the conveying structure stops rotating, and the eccentric shaft rotates to push the force frame forward, so that the cutter contacts the auxiliary blade and completes the complete cutting of the paper.

[0027] Furthermore, the pressure roller one and pressure roller two adopt a segmented structure to form an installation gap, the installation gaps of the pressure roller one and pressure roller two are staggered, a water-passing gap is formed between the pressure roller one and pressure roller two and the inner wall of the guide shell, and the guide shell is equipped with guide blocks arranged at equal intervals at the slit.

[0028] Through the above technical solution, in order to output high-quality paper segments, the disinfectant sprayed from the spray frame is metered, the disinfectant wets the lower section of the paper, the pressure roller rotates to transport the paper downwards, and squeezes the surface disinfectant into the deeper layers of the paper, while squeezing out excess disinfectant. The squeezed-out disinfectant is dispersed by multiple water passage gaps and converges at the slit position. Due to the viscosity of the disinfectant and the obstruction and dispersion by the guide block, the converged disinfectant is redispersed by the guide block and contacts the middle and upper sections of the paper. The disinfectant on the surfaces of pressure rollers one and two will be absorbed by the paper when it contacts the middle and upper sections, so that the paper is wet overall but does not drip.

[0029] Furthermore, the collecting pipe has three air intake manifolds, two of which are rotatably connected to the end of the hollow roller via adapters. The circumferential sidewall of the hollow roller has symmetrically arranged drainage ports, in which mesh plates and germicidal lamps are alternately installed. One of the air intake manifolds is connected to the chip collection chamber. The negative pressure structure is connected to the external atmosphere through a pipe.

[0030] Through the above technical solution, in order to achieve centralized collection of paper scraps, the collecting pipe makes the inside of the hollow roller negative pressure. The air carrying paper scraps enters the hollow roller through the wire mesh, and the paper scraps in the scrap collection chamber will directly enter the collecting pipe and be centrally transported to the outside atmosphere for discharge. Meanwhile, the germicidal lamp will sterilize the paper by irradiation.

[0031] Furthermore, the water supply bottle is slidably fitted with a plug for sealing the opening, and the socket is provided with a push rod in the middle, which can push the plug upward to open the opening of the water supply bottle.

[0032] With the above technical solution, a sealing device is installed at the bottom opening of the water supply bottle to facilitate the replacement of the water supply bottle. During the installation and when not installed, the sealing device seals the opening of the water supply bottle under the action of gravity. When the water supply bottle is plugged into the socket, the top rod pushes the sealing device upward, so that the disinfectant can flow out smoothly. The operation is convenient and prevents overflow during replacement.

[0033] The beneficial effects of this invention are as follows:

[0034] (1) The present invention has a paper jam prevention structure. The processing components of the device form a conveying channel, so that the rolled paper towels can be continuously stretched, flattened, cut, cleaned and moistened and sterilized. The hollow rollers can be far apart from each other, so that the paper wrapped around the outside of the two hollow rollers can be stretched into a single layer of loose state, which facilitates subsequent traction, prevents the tightly rolled paper from having too much resistance to unfolding, causing poor paper output, timely cleaning of free debris, and absorbing and removing odors from the paper towels. It can also be equipped with a sterilizing lamp for sterilization and cleaning of dry paper.

[0035] (2) Through the design of the paper cutting structure and the conveying structure, the present invention clamps and limits the cutting end through the conveying structure when cutting continuous paper, ensuring the smooth start of the second start and the neatness of the cutting end. The end face of the cutter is optimized to increase the cutting force during cutting, ensuring thorough cutting, and is suitable for more resilient facial tissues or washcloths, with strong applicability.

[0036] (3) By optimizing the wetting structure, the present invention adopts quantitative spraying when spraying disinfectant, combined with extrusion dispersion. The first and second pressure rollers are used to extrude and disperse the disinfectant absorbed by the lower section of the paper into the deep layer, and the excess disinfectant is dispersed and squeezed into the guide shell. The disinfectant is absorbed by the continuously descending paper under the further obstruction and dispersion of the guide block, wetting the middle and upper sections of the paper, and obtaining wet paper that is wetted as a whole and does not drip.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0051] like Figures 1-12 As shown, this embodiment provides an intelligent paper towel humidifier for disinfection, sterilization, and deodorization, including a housing 1. The housing 1 is divided into upper and lower parts, which are fixed by snap-fit ​​or bolts. The housing 1 has two layers. The upper layer of the housing 1 forms an upward-opening paper-holding cavity 15 and a socket 13. The paper-holding cavity 15 can hold rolls of dry paper, and the socket 13 can be used to install a water supply bottle 2 to provide disinfectant water separately. The lower layer of the housing 1 forms a device cavity, which is sealed and used to accommodate moving elements and control devices. A paper passage 14 is provided between the device cavity and the paper-holding cavity 15, allowing unprocessed paper to enter. The outer casing 1 has a paper outlet 11 on its bottom side wall, through which the processed paper is discharged for easy access. A control module 17 is located at the front of the outer casing 1, containing a control board and sensing elements. These sensing elements can be contact or non-contact, used to acquire user action signals as the device's start signal. The control board uses a microcontroller and can pre-store control algorithms for intelligent temperature regulation and paper output control. Since microcontrollers are mature technologies for motion control and are existing technology, their internal structure and control principles will not be detailed here.

[0052] The processing assembly installed in the equipment cavity forms a conveying channel 10 between the paper inlet 14 and the paper outlet 11. The conveying channel 10 allows the paper to pass from top to bottom and performs continuous stretching to prevent jamming, cutting and wetting sterilization. The processing assembly includes:

[0053] Regarding anti-paper jam structure 3, refer to... Figure 6 , Figure 7 and Figure 8 The anti-jamming structure 3 is located below the paper feed 14. The anti-jamming structure 3 includes two hollow rollers 31 and a power unit 34. The paper is wound between the two hollow rollers 31. The paper is wound backward on the back side of the rear hollow roller 31. After passing around the rear hollow roller 31, the paper is wound forward and upward on the front side of the front hollow roller 31 in an "8" shape. The power unit 34 drives the hollow rollers 31 to move closer and further away, which can stretch the rolled paper above into a single layer and release it.

[0054] Regarding paper cutting structure 9, refer to... Figure 8The paper cutting structure 9 is located below the anti-jamming structure 3. The paper cutting structure 9 includes a middle shell 91. A reversing cavity 98 is formed in the middle of the middle shell 91, which runs vertically through the paper. The paper passes through the reversing cavity 98 and is reversed to a vertical position for cutting. A chip collection cavity 96 is formed in the middle of the reversing cavity 98 in the middle shell 91. A cutter 93 for cutting the paper is installed in the chip collection cavity 96. The cutter 93 cuts the paper at the position of the chip collection cavity 96 and collects the cut-out chips in a timely manner.

[0055] Regarding wetting structure 4, refer to... Figure 9 , Figure 10 and Figure 12 The wetting structure 4 is located below the paper cutting structure 9. The wetting structure 4 includes a guide shell 41, which is vertically continuous and has a large opening at the top and a narrow slit 44 at the bottom. A spray frame 46 is provided at the top opening of the guide shell 41. The spray frame 46 sprays disinfectant water in an atomized manner downwards and backwards. The guide shell 41 contains a pressure roller 1 42 and a pressure roller 2 43 stacked on top of each other. The pressure roller 1 42 and the pressure roller 2 43 can squeeze the disinfectant water into the inner layer of the paper and squeeze out the excess disinfectant water. When the paper passes through the slit 44, the squeezed disinfectant water is absorbed again to ensure the dispersion of the disinfectant water.

[0056] Regarding conveyor structure 8, refer to... Figure 7 , Figure 8 and Figure 9 The conveying structure 8 conveys the paper and includes a driving roller 81 and a driven roller 82 that are in squeezing contact to clamp the paper. The driving roller 81 and the driven roller 82 are located at the top opening of the reversing cavity 98 to ensure that the paper is smoothly fed into the reversing cavity 98 and changes from a horizontal state to a vertical state. At the same time, the conveying structure 8 also includes two receiving rollers 84. The two receiving rollers 84 are located at the bottom opening of the reversing cavity 98 and are in squeezing contact with each other to clamp the paper below so that the paper can continue to be conveyed after being cut. Furthermore, a guide roller 85 is installed between the paper cutting structure 9 and the wetting structure 4 to carry the cut paper and smoothly convey it to the position of the wetting structure 4 to ensure smooth paper conveying.

[0057] Regarding negative pressure structure 6, refer to... Figure 4 and Figure 8 The negative pressure structure 6 is equipped with an air pump, which can provide a negative pressure environment during operation. The negative pressure structure 6 is connected to the hollow roller 31 and the chip collection chamber 96 through the manifold 61. The manifold 61 is a multi-channel hose that connects the air pump, the two hollow rollers 31 and the chip collection chamber 96 at the same time to realize the negative pressure suction action. The suction at the position of the hollow roller 31 can remove the paper debris before humidification, and the chip collection chamber 96 can eliminate the newly generated debris during slitting in time.

[0058] Regarding water supply bottle 2, refer to... Figure 1 and Figure 2The water supply bottle 2 is installed in the socket 13. The bottom of the water supply bottle 2 has an opening. After being plugged in, the disinfectant water in the water supply bottle 2 can enter the socket 13. A pump 5 is installed between the spray frame 46 and the socket 13. When the pump 5 is working, it can deliver disinfectant water to the spray frame 46 to disinfect, sterilize and humidify the paper towels.

[0059] In a further embodiment, to ensure the paper is flattened in the horizontal direction, a specific configuration is provided, referring to... Figure 7 The outer shell 1 includes an inner shell 16. The inner shell 16 is located between the anti-jamming structure 3 and the paper cutting structure 9 and is provided with an oblique diameter hole 161. When the paper is pulled down through the oblique diameter hole 161, the middle of the oblique diameter hole 161 is designed to bulge forward. The paper will be squeezed and flattened to both sides by the oblique diameter hole 161. The active roller 81 is provided with a spiral strip 83 at both ends. The rotating spiral strip 83 will push the two sides of the paper to the left and right respectively. The rotation of the spiral strip 83 will unfold the paper to the left and right sides, so that it is fully flattened in the horizontal direction.

[0060] In a further embodiment, a specific driving structure 7 is provided as a power source for pushing the paper, referring to... Figure 5 and Figure 6 The equipment cavity contains a drive structure 7, which is equipped with a gear set 71 and a servo motor. The motor shaft of the servo motor is equipped with a drive gear and multiple continuously meshing driven gears. The rotational power is distributed and transmitted to the drive roller 81 and one of the receiving rollers 84 through the gear set 71. The drive roller 81 is connected to one of the transmission gears. The rotation of the drive roller 81 pulls the paper above downwards. One of the receiving rollers 84 is connected to one of the transmission gears. The receiving roller 84 clamps the paper below and continues to push it downwards. The drive structure 7 can drive two hollow rollers 31 to rotate through the gear set 71. Each of the two hollow rollers 31 is connected to a driven gear. The rotation of the hollow rollers 31 can scrape off more free paper scraps. The hollow rollers 31 are in a negative pressure state and attract and remove the paper scraps, ensuring the cleanliness of the equipment and the quality of the paper output.

[0061] In a further embodiment, to facilitate the smooth movement of the two hollow rollers 31 away from each other and towards each other, a specific power component 34 structure is disclosed, referring to... Figure 6 and Figure 7The power unit 34 has two components located at the ends of the two hollow rollers 31, driving both ends simultaneously to ensure that the hollow rollers 31 remain horizontal. The power unit 34 includes connecting frames 341 and sliding sleeves 342. The two connecting frames 341 are rotatably connected to one of the hollow rollers 31, and the two sliding sleeves 342 are fitted onto the ends of the other hollow roller 31. A spring holder 343 is installed between the connecting frame 341 and the inner shell 16. A magnetic suction component 344 is installed on the upper part of the connecting frame 341. The inner shell 16... An electromagnet is installed directly opposite the magnetic suction component 344. The connecting frame 341 can be attracted by the electromagnet and moved backward. At this time, the spring frame 343 is stretched and stored. After the electromagnet is de-energized, the spring frame 343 rebounds and causes the connecting frame 341 to move forward and reset. During the forward movement of the connecting frame 341, the sliding sleeve 342 is pushed upward, causing the two hollow rollers 31 to move away from each other. During the backward movement of the connecting frame 341, the sliding sleeve 342 moves downward and resets, causing the two hollow rollers 31 to move closer to each other, thus completing the reciprocating drive action.

[0062] It should be noted that the power component 34 can be replaced with a telescopic rod that extends forward and backward. Both ends of the telescopic rod have sleeves, which are rotatably connected to the two hollow rollers 31. When the telescopic rod extends, it moves the two hollow rollers 31 away from each other, stretching the paper forward and backward. When the telescopic rod shortens, it moves the two hollow rollers 31 closer to each other, and the stretched paper will be in a loose state that is easy to pull. The power component 34 can also adopt other structures, which can be selected according to the application scenario.

[0063] In a further embodiment, refer to Figure 4 and Figure 5 To improve comfort, a heater 51 is installed at the outlet end of the pump 5. When the temperature is low, the heater 51 can be turned on according to the ambient temperature to heat the paper before the disinfectant is sprayed onto it. The heater 51 is connected in series between the spray frame 46 and the pump 5 through a pipe. The heating temperature can be adjusted by the control module 17 to increase the paper output temperature and thus increase comfort.

[0064] In a further embodiment, to ensure the cleanliness of the paper during long-term use, refer to Figure 7 , Figure 8 and Figure 9The outer casing 1 also includes a cover 12, which is snapped onto the paper receiving cavity 15 with its opening facing downwards, allowing for easy removal for adding paper rolls. A sensor 18 is installed on the outer casing 1 at the receiving roller 84. The sensor 18 detects whether paper has reached the receiving roller 84, promptly identifying paper jams at the cutter 93. If no paper is detected, it indicates that the paper is exhausted or jammed at the cutter 93, prompting the user to address the issue promptly. The alert can be triggered by a built-in alarm with sound and light, or by uploading the problem to a network terminal. It can also provide a working time indication signal for the negative pressure structure 6. After paper cutting, the negative pressure structure 6 stops working, and the conveying structure 8 continues working until the sensor 18 detects... Once the paper is detected to have entered the receiving roller 84, the negative pressure structure 6 is activated to prevent the negative pressure from affecting the smooth downward movement of the paper into the receiving roller 84. At the same time, a sensor 19 is installed on the outer shell 1 above the pressure roller 43. The sensor 19 can detect whether the paper has reached the pressure roller 43 and can serve as the starting signal for disinfectant spraying. When the paper is detected to have reached the pressure roller 43, disinfectant spraying will be activated. After the pressure roller 43 has conveyed the paper for a certain distance, which is no more than half the length of a single section of paper, a signal to stop spraying is issued to ensure that the upper section of paper is relatively dry and can absorb the excess disinfectant squeezed out by the lower section of paper, preventing dripping. In addition, the heater 51 has a built-in temperature sensor that can detect the heating temperature to prevent the disinfectant from being overheated or underheated.

[0065] In a further embodiment, a drive configuration is provided to achieve smooth paper cutting, referring to... Figure 8 and Figure 11The cutter 93 is horizontally arranged, with its serrated edge. This disperses contact with the paper surface, preventing uneven cutting caused by concentrated contact in a short period. It also creates an angle between the blade and the paper, increasing cutting force and resulting in a more thorough cut. This design is suitable for more durable papers, such as face towels and tissues. A secondary blade 97 is installed in the chip collection chamber 96 on top of the cutter 93. The secondary blade 97 and the top of the cutter 93 form a scissor structure, further increasing cutting power and enhancing versatility. A force-bearing frame 92 is installed at the unsharpened end of the cutter 93, with an arc-shaped contact surface at its rear end. A pusher is installed on the top of the middle shell 91. The eccentric shaft 95 of the moving force frame 92 has three protruding side shafts. Each 120-degree rotation can complete a full forward push of the force frame 92. When cutting paper, the conveying structure 8 stops rotating, and the eccentric shaft 95 rotates to push the force frame 92 forward, so that the cutter 93 contacts the auxiliary blade 97, completing the complete cutting of the paper. Furthermore, a reset member 94 is installed between the cutter 93 and the middle shell 91. When the side shafts are disengaged from the force frame 92, the reset member 94 drives the cutter 93 to move backward, thus achieving smooth reset. When not cutting paper, the reset member 94 pulls the cutter 93 backward to ensure the unobstructed flow of the conveying channel 10.

[0066] It should be emphasized that the eccentric shaft 95 is equipped with a single-door motor for rotational drive. Alternatively, the entire drive configuration can be replaced with a telescopic rod. When the telescopic rod extends, it can move the cutter 93 forward to perform the cutting operation. When the telescopic rod shortens, it can move the cutter 93 backward to complete the reset operation. The specific choice can be made according to the usage scenario.

[0067] In a further embodiment, to output high-quality paper segments, refer to Figure 10 and Figure 12 The disinfectant sprayed from the spray frame 46 is quantitatively controlled by the control module 17 to ensure that each section of paper receives the appropriate amount of disinfectant. In operation, the disinfectant wets the lower section of the paper, and the pressure roller 42 rotates to convey the paper downwards, squeezing the surface disinfectant into the deeper layers of the paper while expelling excess disinfectant. The pressure rollers 42 and 43 are segmented, forming an installation gap 47. The installation gaps 47 between the pressure rollers 42 and 43 are staggered, and the expelled disinfectant is roughly dispersed through multiple water-passing gaps, and then dispersed further below. The water converges at the slit 44, and a water-passing gap is formed between the pressure roller 1 42 and the pressure roller 2 43 and the inner wall of the guide shell 41 to ensure that the disinfectant water flowing down from above passes smoothly. The disinfectant water on the surface of the pressure roller 1 42 and the pressure roller 2 43 will be absorbed by the paper when it comes into contact with the middle and upper section of the paper. The guide shell 41 is equipped with guide blocks 45 arranged at equal intervals at the slit 44. Due to the viscosity of the disinfectant water and the obstruction and further dispersion by the guide blocks 45, the collected disinfectant water is redispersed by the guide blocks 45 and dispersed into contact with the middle and upper section of the paper, so that the paper is wet as a whole but does not drip.

[0068] In a further embodiment, to achieve centralized collection of paper scraps, refer to Figure 5 and Figure 8 The collecting pipe 61 has three air intake manifolds, which create a negative pressure inside the hollow roller 31. Two of the air intake manifolds are rotatably connected to the ends of the hollow roller 31 via adapters, ensuring continuity without affecting the rotation of the hollow roller 31. Symmetrically arranged inlet ports are provided on the circumferential sidewall of the hollow roller 31. A wire mesh 33 and a germicidal lamp 32 are installed alternately in the inlet ports. Air carrying paper scraps enters the hollow roller 31 through the wire mesh 33, while the germicidal lamp 32 sterilizes the paper with light. One of the air intake manifolds is connected to the scrap collection chamber 96. The negative pressure structure 6 is connected to the external atmosphere through a pipe. The paper scraps in the scrap collection chamber 96 directly enter the collecting pipe 61 and are centrally transported to the external atmosphere for discharge.

[0069] In a further embodiment, to facilitate the replacement of water supply bottle 2, refer to... Figure 3 The water supply bottle 2 has a slidable plug 21 for sealing the opening. The plug 21 has a circular rubber stopper on top and a cross-shaped bracket below. When the plug 21 is not installed or during installation, the plug 21 seals the opening of the water supply bottle 2 under the action of gravity. At the same time, the socket 13 has a top rod in the middle. When the water supply bottle 2 is inserted, the top rod pushes the plug 21 upward and the bracket enters the water supply bottle 2 a certain distance, so that the disinfectant can flow out smoothly. It is easy to operate and prevents spillage during replacement.

[0070] It should be emphasized that an opening can be set at the top of water supply bottle 2, and a top plate can be screwed into the opening. By unscrewing the top plate, disinfectant can be added directly, making the operation more convenient.

[0071] The working principle of this embodiment is as follows:

[0072] Rolls of dry paper towels are placed individually in the paper receiving chamber 15, with the paper ends extending through the paper outlet 14 into the processing assembly. Disinfectant is contained separately in the water supply bottle 2 and stored independently to avoid evaporation or contamination during storage.

[0073] When the paper is picked up, the trigger control module 17 causes the conveying structure 8 to work and convey the paper downward. The hollow roller 31 of the anti-jamming structure 3 will move back and forth, pulling the paper that is wrapped in the figure "8" outside the two hollow rollers 31 from the wound state to a loose state, reducing the conveying resistance and preventing the paper from being torn by the conveying structure 8. It can also prevent paper jams caused by insufficient traction.

[0074] While the tearing action is being performed, the hollow roller 31 is in a negative pressure suction state, which draws the free debris out through the hollow roller 31. The germicidal lamp 32 installed on the hollow roller 31 emits ultraviolet light to perform the sterilization action.

[0075] During conveying, the inclined diameter hole 161, together with the spiral strips 83 at both ends of the drive roller 81, pulls the paper to the left and right sides to ensure the paper is flat and facilitates subsequent slitting and impregnation.

[0076] When the conveyed paper reaches the length of a single section, the conveying structure 8 stops rotating, the cutter 93 extends to cut the paper, and at the same time, it sucks up and removes slag to ensure the cleanliness of the inside of the equipment and the paper itself. The paper above the cutter 93 is clamped by the driving roller 81 and the driven roller 82 to prevent it from retracting upward and affecting the next paper output. The paper below the cutter 93 is clamped by the receiving roller 84, so that the paper is in a flat state before cutting to ensure a neat cut.

[0077] The cut paper continues to be conveyed until it enters the wetting structure 4. It can also be designed according to the unit length of the paper segment to ensure that when the upper end of the paper is cut, the lower end of the paper is already in the wetting structure 4. When the paper is conveyed downward, the wetting structure 4 sprays a certain amount of disinfectant water backward and downward through the spray frame 46 to wet the lower section of the paper. The pressure roller 1 42 and pressure roller 2 43 squeeze and disperse the disinfectant water absorbed in the lower section of the paper into the deeper layer, and disperse the excess disinfectant water into the guide shell 41. Under the further obstruction and dispersion of the guide block 45, the disinfectant water is absorbed by the continuously descending paper, wetting the middle and upper sections of the paper, resulting in wet paper that is fully wetted and does not drip.

[0078] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
