[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-Figure 6The present embodiment provides an electric desktop cleaning device, comprising a cleaning shell 1 with a hollow interior, an adsorption component 2 and a spraying component 3. The front end of the cleaning shell 1 is provided with an adsorption port 101 and a spraying port 102. The adsorption component 2 is arranged in the cleaning shell 1, and the adsorption end of the adsorption component 2 is connected to the adsorption port 101; the spraying component 3 is arranged in the cleaning shell 1, and the output end of the spraying component 3 is connected to the spraying port 102, and is used to spray viscous foam on the desktop. The adsorption component 2 comprises an adsorption pump 201, an air suction pipe 203, a battery and a power switch. The battery is arranged in the cleaning shell 1, and the power switch is arranged on the top of the cleaning shell 1. The power switch is respectively connected to the battery and the adsorption pump. The pump 201 is connected with an electric wire, and the power switch is used to lock or release the circuit connection relationship between the battery and the adsorption pump 201. The suction pipe 203 and the adsorption pump 201 are both arranged in the cleaning shell 1. The two ends of the suction pipe 203 are respectively connected with the adsorption port 101 and the cleaning shell 1. The adsorption pump 201 and the suction pipe 203 are connected with each other. The adsorption component 2 adsorbs the dust or foam on the desktop into the cleaning shell 1 through the adsorption port 101; by providing a spraying component 3, the spraying component 3 sprays the sticky foam on the desktop, and the foam will adhere to the dust and stains on the desktop, and then the foam that has completed the adhesion of dust and stains will be adsorbed into the cleaning shell through the adsorption component 2. 1, the cleaning process of the desktop is completed; it is worth noting that, since the adsorption component 2 of the present solution adopts an electric suction method to clean the dust and stains on the desktop, the dust and stains hidden in the depression of the desktop, or the dust and stains existing at the contact point between the protrusion of the desktop and the desktop will move toward the cleaning shell 1 due to the air pressure difference, so as to achieve the cleaning process of the desktop; in addition, there is a situation that the dust and stains attached to the depression of the desktop, or the dust and stains attached to the contact point between the protrusion of the desktop and the desktop are difficult to be adsorbed in the cleaning shell 1 by the air pressure difference, and at this time, the dust and stains that are difficult to remove are moved toward the cleaning shell 1. The sticky foam is sprayed, and the sticky foam will stick to dust and stains. In addition, the volume of the foam body is large, so this setting can easily realize the adsorption component 2 to adsorb the foam that has adhered to dust and stains, and finally achieve the cleaning of the desktop, which solves the problem that the existing desktop cleaners all use rollers to adsorb particles, and bring the particles into the shell for collection to achieve the cleaning of the desktop; however, in actual situations, the surface of the table is not flat, and there may be irregular depressions or protrusions in some parts of it. Such a desktop will make it impossible for the dust and stains in the contact between the depressions or protrusions and the desktop to be removed by the rollers, and thus the problem of failing to complete the cleaning of the desktop.

[0022] Specifically, the spray assembly 3 of the present scheme includes a spray pump 301, a spray tank 302 filled with viscous foam, and a nozzle 303. The nozzle 303 is sealed on the spray port 102. The spray pump 301 and the spray tank 302 are both arranged in the cleaning shell 1. The spray pump 301 is respectively connected to the spray tank 302 and the nozzle 303. By providing the spray assembly 3, when the spray pump 301 starts working, the viscous foam in the spray tank 302 will be sprayed onto the table through the nozzle 303, thereby realizing the spray treatment of the table.

[0023] Specifically, the adsorption component 2 of the present scheme includes an adsorption pump 201, an internally hollow storage box 202, an air suction pipe 203 and an exhaust pipe 204. The cleaning shell 1 is also provided with an exhaust port 103. The storage box 202 and the adsorption pump 201 are both arranged in the cleaning shell 1. The two ends of the exhaust pipe 204 are respectively connected to the exhaust port 103 and one end of the storage box 202, and the two ends of the air suction pipe 203 are respectively connected to the adsorption port 101 and the other end of the storage box 202. The adsorption pump 201 and the exhaust pipe 204 are connected to each other. By providing the adsorption component 2, the connection point between the adsorption pump 201 and the exhaust pipe 204 is located in the middle of the exhaust pipe 204. When the adsorption pump 201 starts to work, During operation, the adsorption pump 201 will exhaust air toward the position of the exhaust port 103, thereby causing an air pressure difference at both ends of the exhaust pipe 204, and the gas located at the end of the exhaust pipe 204 close to the storage box 202 will flow toward the end of the exhaust pipe 204 close to the exhaust port 103; similarly, in the storage box 202, the gas in the storage box 202 close to the end of the suction pipe 203 will flow toward the position in the storage box 202 close to the end of the exhaust pipe 204; in the suction pipe 203, the air located at the adsorption port 101 will flow toward the end of the suction pipe 203 close to the storage box 202, and finally the dust and stains will be adsorbed into the storage box 202 through the adsorption port 101.

[0024] Furthermore, since the present solution utilizes the suction port 101 to absorb dust and stains through the suction force of the air pressure difference, the distance between the suction port 101 and the desktop cannot be too far during the actual operation of the device. Based on this, the front end of the cleaning shell 1 of the present solution is extended and bent in the direction close to the desktop, and the suction port 101 is arranged on the front end surface of the cleaning shell 1. Along the axial direction perpendicular to the end face of the suction port 101, the distance between the suction port 101 and the desktop is 3 cm. Through such a setting, when the device is placed on the desktop, the suction port 101 can absorb the dust and stains on the desktop along the axial direction perpendicular to the end face of the suction port 101.

[0025] Furthermore, in the present embodiment, the spray port 102 is arranged at the extended bend at the front end of the cleaning shell 1, the spray port 102 is arranged at an angle, and the horizontal distance between the suction port 101 and the projection onto the desktop along the axial direction perpendicular to the end face of the spray port 102 is 5cm-8cm; through such a setting, when the sticky foam is sprayed out from the spray port 102, it will adhere to the desktop at a horizontal distance of 5cm-8cm from the suction port 101. At this time, the suction port 101 cannot immediately absorb the sprayed sticky foam into the cleaning shell 1, which allows the sticky foam to have sufficient time to absorb all the dust and stains in the area where the foam is attached, and then the device absorbs the foam with dust and stains into the cleaning shell 1.

[0026] In addition, it should be noted that since the suction duct 203 and the exhaust duct 204 are interconnected through the storage box 202, in order to prevent the dust and stains in the storage box 202 from being re-discharged outside the storage box 202 through the exhaust duct 204, the storage box 202 of this scheme is filled with clean water 4. When dust and stains enter the storage box 202 through the suction duct 203, due to the presence of the clean water 4, the dust and stains will fall into the clean water 4 and cannot be sucked into the exhaust duct 204 by the wind force at one end of the exhaust duct 204, thereby avoiding the dust and stains from entering the storage box 202 and being re-discharged outside the storage box 202 through the exhaust duct 204.

[0027] Furthermore, in order to ensure that the dust and stains sucked into the storage box 202 will first adhere to the clean water 4, rather than being adsorbed into the exhaust duct 204 due to the adsorption force of the exhaust duct 204 located at the other end of the storage box 202, the distance between the end of the suction duct 203 and the storage box 202 that is interconnected and the end of the exhaust duct 204 and the storage box 202 that is interconnected is greater than the distance between the end of the suction duct 203 and the storage box 202 that is interconnected and the highest liquid level of the clean water 4; in addition, the end of the suction duct 203 of the present scheme that is close to the storage box 202 is vertically interconnected with the end of the top of the storage box 202; similarly, the end of the exhaust duct 204 of the present scheme that is close to the storage box 202 is vertically interconnected with the end of the top of the storage box 202 It is interconnected with the other end of the top of the storage box 202; through such an arrangement, when dust and stains are absorbed into the storage box 202 from the suction pipe 203, the dust and stains will be moved by the vertical downward force, that is, the force applied to the dust and stains in the direction close to the clean water 4 is greater than the suction force applied to them from the exhaust pipe 204. Also, since the distance between the dust and stains that have just entered the storage box 202 and the clean water 4 is smaller than the distance between them and the exhaust pipe 204, it can be ensured that the dust and stains sucked into the storage box 202 will first adhere to the clean water 4, rather than being absorbed into the exhaust pipe 204 due to the adsorption force of the exhaust pipe 204 located at the other end of the storage box 202.

[0028] It should also be noted that the height of the connection between the suction duct 203 and the storage box 202 in this scheme is lower than the height of the connection between the exhaust duct 204 and the storage box 202. Such a setting can prevent dust and stains from being adsorbed into the exhaust duct 204 through the adsorption force of the exhaust duct 204, and can also greatly increase the distance between the exhaust duct 204 and the liquid surface of the clean water 4, thereby ensuring that the exhaust duct 204 can absorb the gas in the storage box 202, thereby ensuring the adsorption force of the adsorption port 101.

[0029] It is worth noting that, since the storage box 202 of the present solution is respectively connected with the suction pipe 203 and the exhaust pipe 204, in order to prevent the cleaning water 4 in the storage box 202 from flowing out of the cleaning shell 1 through the suction pipe 203 or the exhaust pipe 204 and affecting the adsorption effect of the adsorption component 2 on dust and stains, the present solution is further provided with a liquid level sensor 5, which is arranged in the storage box 202. The setting height of the liquid level sensor 5 is between the top surface of the storage box 202 and the highest liquid level of the cleaning water 4. The liquid level sensor 5 is used to detect the liquid level of the cleaning water 4. 5 is connected to the adsorption pump 201 for communication; when the amount of clean water 4 filled in the storage box 202 is too much, or the device is tilted during use, causing the liquid level of the clean water 4 to rise, so that the clean water 4 and the liquid level sensor 5 contact each other, at this time, after the liquid level sensor 5 recognizes the rising liquid level of the clean water 4, it will control the adsorption pump 201 to stop working. On the one hand, this approach can ensure that the adsorption pump 201 will not be damaged by water ingress; on the other hand, it reminds the user that the liquid level of the clean water 4 is too high at this time, and it is necessary to reduce the filling amount of the clean water 4 or adjust the use angle of the device.

[0030] Furthermore, the present solution also includes a water-proof membrane 6, which is sealed at the connection between the exhaust pipe 204 and the storage box 202. Such a setting can prevent the clean water 4 in the storage box 202 from flowing to the adsorption pump 201 through the exhaust pipe 204, causing damage to the adsorption pump 201; at the same time, the water-proof membrane 6 will not prevent the normal flow of air, ensuring that the adsorption component 2 of the present solution can work normally.

[0031] According to the above embodiments, the present solution needs to be placed on a desktop to absorb dust and stains on the desktop normally; in addition, when the device is placed on a desktop, it is also necessary to ensure that the bottom surface of the device and the desktop remain parallel to each other and cannot be tilted, so as to ensure that the clean water 4 in the storage box 202 does not flow into the suction pipe 203 through the connecting port between the suction pipe 203 and the storage box 202, thereby affecting the dust and stain absorption effect of the storage box 202; based on this, in order to limit the use of the device, the present solution also includes The pressing unit 7 includes a pressing module 701, a pressing rod 702 and a pressing spring 703. A pressing slot 104 is provided at the bottom of the cleaning housing 1. It should be noted that the bottom of the cleaning housing 1 of the present solution is actually the bottom of the storage box 202, that is, the pressing slot 104 is provided at the bottom of the storage box 202; the pressing module 701 is provided in the pressing slot 104, the pressing rod 702 is slidably provided in the pressing slot 104, and a pressing groove 104 is formed between the pressing rod 702 and the pressing slot 104. The pressing spring 703 is arranged in the pressing space, and the two ends of the pressing spring 703 are respectively connected to the pressing rod 702 and the pressing slot 104, and the pressing module 701 is respectively connected to the spray pump 301 and the adsorption pump 201, and the pressing rod 702 can lock or release the pressing cooperation relationship between it and the pressing module 701; by providing the pressing unit 7, the force of the pressing spring 703 with a normal length on the pressing rod 702 is greater than the weight of the device itself, so the cleaning shell 1 in the normal state will tilt. It is set obliquely. It should be noted that the degree of inclination of the cleaning shell 1 under normal conditions is not enough to make the liquid level of the cleaning water 4 in the storage box 202 higher than the liquid level sensor 5; when using the device, it is necessary to manually press the cleaning shell 1 so that the pressing rod 702 overcomes the force of the pressing spring 703 and slides in the direction of the pressing slot 104 until the pressing rod 702 and the pressing module 701 are in a pressing fit relationship. At this time, the pressing module 701 controls the spray pump 301 and the adsorption pump 201 to work normally.

[0032] According to the above embodiment, it can be known that during use of the device, it is necessary to ensure that the bottom surface of the cleaning shell 1 remains parallel to the desktop. If it is accidentally tipped over during use, the cleaning water 4 in the storage box 202 will flow into the suction pipe 203, thereby causing the cleaning water 4 to remain in the suction pipe 203. At this time, when the device is used to absorb dust on the desktop, the absorbed dust will adhere to the inner wall of the suction pipe 203, affecting the subsequent cleaning effect of the desktop. Based on this, in order to solve this problem, the present solution is provided with a sealing assembly 8, which includes a hinge plate 801, a hinge spring 802 and a drive unit 9, one end of the hinge plate 801 is hingedly arranged at the connection between the suction pipe 203 and the storage box 202, the hinge spring 802 is arranged in the storage box 202, and the two ends of the hinge spring 802 are respectively connected to the hinge plate 80 1 is connected to the storage box 202, and the driving unit 9 is arranged in the suction pipe 203. The driving unit 9 controls the closing of the hinged plate 801 by connecting with the hinged plate 801; specifically, when the driving unit 9 applies a force to the hinged plate 801, the hinged plate 801 will rotate along the hinged end of the connection between the suction pipe 203 and the storage box 202, so as to achieve a sealing fit between the connection between the hinged plate 801, the suction pipe 203 and the storage box 202, and prevent the water in the storage box 202 from flowing into the suction pipe 203; when the driving unit 9 releases the force applied to the hinged plate 801, the hinged plate 801 will release the sealing fit relationship between the connection between the suction pipe 203 and the storage box 202 due to the force of the hinged spring 802, so that the adsorption component 2 can normally adsorb the dust and stains on the desktop into the storage box 202.

[0033] Furthermore, the driving unit 9 of the present scheme includes an internally hollow telescopic rod 901, a telescopic block 904, a telescopic spring 902 and a connecting rope 903, the telescopic rod 901 is arranged in one end of the suction pipe 203 close to the storage box 202, it is worth noting that the end of the suction pipe 203 close to the storage box 202 is vertically arranged on the top of the storage box 202, and a telescopic slot is provided on the side wall of the end of the suction pipe 203 close to the storage box 202, it is worth noting that the axial direction of the telescopic slot is perpendicular to the axial direction of the end of the suction pipe 203 close to the storage box 202, the telescopic rod 901 is arranged in the telescopic slot, and the axial direction of the telescopic rod 901 is kept consistent with the axial direction of the telescopic slot. The telescopic block 904 is slidably arranged in the telescopic rod 901, and there is a telescopic space between the telescopic block 904 and the bottom of the telescopic rod 901, and the telescopic spring 902 is arranged in the telescopic space, and the two ends of the telescopic spring 902 are respectively connected to the telescopic block 904 and the telescopic rod 901, and the two ends of the connecting rope 903 are respectively connected to the end of the hinged plate 801 away from its hinged end and the telescopic block 904; by providing a driving unit 9, when the device is used, if it accidentally falls, the cleaning shell 1 will tip over. At this time, the cleaning water 4 in the storage box 202 will flow out through the gap between the hinged plate 801 and the connection between the suction pipe 203 and the storage box 202. First, the cleaning water 4 will flow to It should be noted that inside the driving unit 9, due to the tipping of the cleaning shell 1, the axial direction of the telescopic rod 901 is consistent with the direction of gravity, and the cleaning water 4 will flow toward the bottom of the telescopic rod 901 due to the force of gravity. As the weight of the cleaning water 4 flowing into the telescopic rod 901 increases, the telescopic block 904 will move toward the bottom of the telescopic rod 901, and then pull the connecting rope 903, driving the hinged plate 801 to achieve a sealed fit at the connection between it and the suction pipe 203 and the storage box 202; similarly, when the device is manually rearranged, the axial direction of the telescopic rod 901 and the direction of gravity remain perpendicular to each other, and the cleaning water 4 located in the telescopic rod 901 will The force flows back to the hinged plate 801. Since the connection between the hinged plate 801 and the air suction pipe 203 and the storage box 202 is still in a sealed state, the clean water 4 will stay on the hinged plate 801. As the amount of clean water 4 flowing out to the telescopic rod 901 increases, the telescopic block 904 is reset under the action of the telescopic spring 902, which causes the force of the connecting rope 903 on the hinged plate 801 to disappear. At this time, the hinged plate 801 is reset under the action of the hinge spring 802, and the hinged plate 801 releases the sealing relationship between the connection between the hinged plate 801 and the air suction pipe 203 and the storage box 202, and the clean water 4 on the hinged plate 801 flows back into the storage box 202. It is worth noting that in order to ensure that the clean water 4 on the hinged plate 801 can flow back into the storage box 202 smoothly, the hinged plate 801 is located in the storage box 202 when it is hinged and rotated.

[0034] In addition, it is worth noting that in order to ensure that the clean water 4 flowing out can all flow into the telescopic rod 901 when the cleaning shell 1 is tipped over, the width of the telescopic rod 901 of this solution is equal to the height dimension of the inner wall of one side of the suction pipe 203, so as to ensure that the clean water 4 flowing out can all flow into the telescopic rod 901. In addition, the drive unit 9 of this solution is provided with a plurality of drive units 9, and the plurality of drive units 9 are matched with the plurality of inner side walls at one end of the suction pipe 203 in a one-to-one correspondence, and any drive unit 9 is provided on the inner side wall at one end of the corresponding suction pipe 203. Such a setting can ensure that the clean water 4 can always flow into at least one telescopic rod 901 when the cleaning shell 1 is tipped over; on the one hand, such a setting can ensure that the drive unit 9 can respond in time and work normally when the cleaning shell 1 is tipped over; on the other hand, it ensures that the clean water 4 will not adhere to the rest of the suction pipe 203 when it flows out of the storage box 202.
