An electric desktop cleaning device

Abstract

The present invention relates to an electric desktop cleaning device, belonging to the technical field of electric dust removal. By providing a spraying component, the spraying component sprays sticky foam onto the desktop, and the foam will adhere to the dust and stains on the desktop. Then, through the adsorption component, the foam that has adhered to the dust and stains is adsorbed into the cleaning housing together, completing the cleaning of the desktop. It should be noted that since the adsorption component of this solution uses an electric suction method to clean the dust and stains on the desktop, the dust and stains hidden in the recesses of the desktop, or the dust and stains existing at the contact between the protrusions and the desktop of the desktop will move towards the cleaning housing due to the air pressure difference, realizing the cleaning of the desktop.

Description

Technical Field

[0001] The present invention belongs to the technical field of electric dust removal, and particularly relates to an electric desktop cleaning device. Background Art

[0002] In an office, the most common office supply is a desk. During the use of the desk, some dust and impurities will adhere to its desktop. In order to maintain the cleanliness of the desktop, it is necessary to clean it through a desktop cleaning device.

[0003] For example, the utility model patent with the patent authorization announcement number: CN210582434U discloses a desktop cleaner, which includes a housing, an upper cover and a roller; a columnar bearing recess arched upward and shaft seats at both ends of the columnar bearing recess are formed at the bottom of the housing, and a dust inlet groove is opened at the top of the columnar bearing recess; the roller is inserted into the shaft seat by means of shaft protrusions at both ends to form a rolling positioning structure; the two edges of the roller surface close to the dust inlet groove can send the adsorbed particulate dust into the housing through the dust inlet groove.

[0004] Based on the retrieval of the patent authorization announcement number and combined with its deficiencies, it is found that:

[0005] Existing desktop cleaners all use rollers to adsorb particulate matter and bring the particulate matter into the housing 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. Such a desktop will cause the dust and stains existing at the contact between the depression or protrusion and the desktop to be unable to be removed by the roller, and thus the cleaning of the desktop cannot be completed. Summary of the Invention

The battery is arranged inside the cleaning housing, and the power switch is arranged on the top of the cleaning housing. The power switch is electrically connected to the battery and the adsorption pump respectively, and the power switch is used to lock or release the electrical connection relationship between the battery and the adsorption pump. The air suction pipe and the adsorption pump are both arranged inside the cleaning housing. The two ends of the air suction pipe are respectively in communication with the adsorption port and the interior of the cleaning housing, and the adsorption pump is in communication with the air suction pipe.

[0009] As a preferred technical solution of the present invention, the spraying component includes a spraying pump, a spraying tank filled with sticky foam inside, and a nozzle. The nozzle is hermetically arranged on the spraying port. The spraying pump and the spraying tank are both arranged inside the cleaning housing, and the spraying pump is respectively connected to the spraying tank and the nozzle.

[0010] As a preferred technical solution of the present invention, the adsorption component further includes a storage box with a hollow interior and an exhaust pipe. The cleaning housing is also provided with an exhaust port. The storage box is arranged inside the cleaning housing. The two ends of the exhaust pipe are respectively in communication with the exhaust port and one end of the storage box. The two ends of the air suction pipe are respectively in communication with the adsorption port and the other end of the storage box. The adsorption pump is in communication with the exhaust pipe.

[0011] As a preferred technical solution of the present invention, the front end of the cleaning housing extends and bends towards the direction close to the desktop. The adsorption port is arranged on the front end face of the cleaning housing. Along the axis perpendicular to the end face of the adsorption port, the distance between the adsorption port and the desktop is 3 cm.

[0012] As a preferred technical solution of the present invention, the spraying port is arranged at the extended and bent part of the front end of the cleaning housing. The spraying port is inclined. The horizontal distance between the adsorption port and the projection on the desktop projected along the axis perpendicular to the end face of the spraying port is 5 cm - 8 cm.

[0013] As a preferred technical solution of the present invention, the storage box is filled with cleaning water.

[0014] As a preferred technical solution of the present invention, the distance between the end where the air suction pipe communicates with the storage box and the end where the exhaust pipe communicates with the storage box is greater than the distance between the end where the air suction pipe communicates with the storage box and the highest liquid level of the cleaning water.

[0015] As a preferred technical solution of the present invention, a liquid level sensor is further provided. The liquid level sensor is arranged in the storage box. The installation height of the liquid level sensor is between the top surface in the storage box and the highest liquid level of the cleaning water.

[0018] The beneficial effects of the present invention are as follows:

[0019] By setting up a spraying component, the spraying component sprays sticky foam onto the desktop. The foam will adhere to the dust and stains on the desktop. Then, through the adsorption component, the foam that has adhered to the dust and stains is adsorbed into the cleaning housing together, completing the cleaning of the desktop. It should be noted that since the adsorption component in this solution uses an electric suction method to clean the dust and stains on the desktop, the dust and stains hidden in the recesses of the desktop or the dust and stains existing at the contact points between the protrusions and the desktop of the desktop will move towards the cleaning housing due to the air pressure difference, achieving the cleaning of the desktop. In addition, there is a situation where it is difficult to adsorb the dust and stains attached to the recesses of the desktop or the contact points between the protrusions and the desktop of the desktop into the cleaning housing through the air pressure difference. At this time, sticky foam is sprayed towards these difficult-to-remove dust and stains. The sticky foam will stick to the dust and stains, and combined with the relatively large volume of the foam body, such a setting can easily enable the adsorption component to adsorb the foam that has adhered to the dust and stains, ultimately achieving the cleaning of the desktop, and solving the problem that existing desktop cleaners all use roller wheels to adsorb particulate matter, bringing the particulate matter into the housing 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 recesses or protrusions in some parts. Such a desktop will cause the dust and stains existing in its recesses or at the contact points between the protrusions and the desktop to be unable to be removed by the roller wheels, and thus the cleaning of the desktop cannot be completed.

[0029] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0030] Please refer to Figures 1-6, this embodiment provides an electric desktop cleaning device, which includes a cleaning housing 1 with a hollow interior, an adsorption component 2, and a spraying component 3. An adsorption port 101 and a spraying port 102 are opened at the front end of the cleaning housing 1. The adsorption component 2 is arranged inside the cleaning housing 1, and the adsorption end of the adsorption component 2 is connected to the adsorption port 101; the spraying component 3 is arranged inside the cleaning housing 1, and the output end of the spraying component 3 is in communication with the spraying port 102, and is used to spray sticky foam onto the desktop. The adsorption component 2 includes an adsorption pump 201, an air suction pipe 203, a battery, and a power switch. The battery is arranged inside the cleaning housing 1, and the power switch is arranged on the top of the cleaning housing 1. The power switch is electrically connected to the battery and the adsorption pump 201 respectively. The power switch is used to lock or release the circuit connection relationship between the battery and the adsorption pump 201. Both the air suction pipe 203 and the adsorption pump 201 are arranged inside the cleaning housing 1. The two ends of the air suction pipe 203 are respectively in communication with the adsorption port 101 and the inside of the cleaning housing 1, and the adsorption pump 201 is in communication with the air suction pipe 203. The adsorption component 2 adsorbs the dust or foam on the desktop into the cleaning housing 1 through the adsorption port 101; by setting the spraying component 3, the spraying component 3 sprays sticky foam onto the desktop, and the foam will adhere to the dust and stains on the desktop. Then, the adsorption component 2 adsorbs the foam that has adhered to the dust and stains into the cleaning housing 1 together to complete the cleaning of the desktop; it is worth noting that since the adsorption component 2 of this solution uses an electric suction method to clean the dust and stains on the desktop, the dust and stains hidden in the recesses of the desktop, or the dust and stains existing at the contact between the protrusions and the desktop of the desktop will move towards the inside of the cleaning housing 1 due to the air pressure difference, realizing the cleaning of the desktop; in addition, there is a situation where it is difficult to adsorb the dust and stains attached to the recesses of the desktop, or the dust and stains attached to the contact between the protrusions and the desktop of the desktop into the cleaning housing 1 by means of air pressure difference. At this time, spray sticky foam on these difficult-to-remove dust and stains. The sticky foam will stick to the dust and stains, and the volume of the foam body is relatively large. Such a setting can easily enable the adsorption component 2 to adsorb the foam that has adhered to the dust and stains, and finally realize the cleaning of the desktop, solving the problem that existing desktop cleaners all use rollers to adsorb particulate matter and bring the particulate matter into the housing for collection to achieve the cleaning of the desktop; however, in actual situations, the table surface is not flat, and there may be irregular recesses or protrusions in some parts. Such a desktop will cause the dust and stains existing in its recesses or at the contact between the protrusions and the desktop to be unable to be removed by the rollers, and thus the cleaning of the desktop cannot be completed.

[0031] Specifically, the spraying assembly 3 of this solution includes a spraying pump 301, a spraying tank 302 filled with viscous foam inside, and a nozzle 303. The nozzle 303 is sealingly arranged on the spraying port 102. Both the spraying pump 301 and the spraying tank 302 are arranged inside the cleaning housing 1. The spraying pump 301 is respectively connected to the spraying tank 302 and the nozzle 303. By providing the spraying assembly 3, when the spraying pump 301 starts to work, the viscous foam contained in the spraying tank 302 will be ejected onto the tabletop through the nozzle 303, realizing the spraying treatment of the tabletop.

[0032] Specifically, the adsorption assembly 2 of this solution includes an adsorption pump 201, a hollow storage box 202 inside, a suction air duct 203, and an exhaust air duct 204. The cleaning housing 1 is also provided with an exhaust air port 103. Both the storage box 202 and the adsorption pump 201 are arranged inside the cleaning housing 1. The two ends of the exhaust air duct 204 are respectively communicated with the exhaust air port 103 and one end of the storage box 202. The two ends of the suction air duct 203 are respectively communicated with the adsorption port 101 and the other end of the storage box 202. The adsorption pump 201 is communicated with the exhaust air duct 204; by providing the adsorption assembly 2, the connection between the adsorption pump 201 and the exhaust air duct 204 is located in the middle of the exhaust air duct 204. When the adsorption pump 201 starts to work, the adsorption pump 201 will exhaust air towards the position of the exhaust air port 103, thereby causing a pressure difference at both ends of the exhaust air duct 204. The gas at the end of the exhaust air duct 204 close to the storage box 202 will flow towards the end of the exhaust air duct 204 close to the exhaust air port 103; similarly, inside the storage box 202, the gas at the end of the storage box 202 close to the suction air duct 203 will flow towards the position at the end of the storage box 202 close to the exhaust air duct 204; inside the suction air duct 203, the air at the adsorption port 101 will flow towards the end of the suction air duct 203 close to the storage box 202, and finally, it is realized that dust and stains will be adsorbed into the storage box 202 through the adsorption port 101.

[0033] Furthermore, since the adsorption of dust and stains by this solution using the adsorption port 101 is achieved through the suction force of the pressure difference, therefore, during the actual operation of the device, the distance between the adsorption port 101 and the tabletop cannot be too far apart. Based on this, the front end of the cleaning housing 1 of this solution extends and bends towards the direction close to the tabletop. The adsorption port 101 is arranged on the front end face of the cleaning housing 1. Along the axis perpendicular to the end face of the adsorption port 101, the distance between the adsorption port 101 and the tabletop is 3 cm; through such a setting, when the device is placed on the tabletop, the adsorption port 101 can adsorb the dust and stains on the tabletop along the axis perpendicular to the end face of the adsorption port 101.

[0034] Further, the spraying port 102 of this solution is arranged at the extended bending part at the front end of the cleaning housing 1. The spraying port 102 is inclined. The horizontal distance between the adsorption port 101 and the projection on the desktop projected along the axis perpendicular to the end face of the spraying port 102 is 5 cm - 8 cm. With such a setting, when the sticky foam is ejected from the spraying port 102, it will adhere to the desktop at a horizontal distance of 5 cm - 8 cm from the adsorption port 101. At this time, the adsorption port 101 cannot immediately adsorb the ejected sticky foam into the cleaning housing 1, allowing the sticky foam to have sufficient time to completely adsorb the dust and stains in the area adhered to by the foam. Then, the device adsorbs the foam adhered with dust and stains into the cleaning housing 1.

[0035] In addition, it should be noted that since the suction pipe 203 and the exhaust pipe 204 are interconnected through the storage box 202, to prevent the dust and stains in the storage box 202 from being discharged out of the storage box 202 again through the exhaust pipe 204, the storage box 202 of this solution is filled with cleaning water 4. When the dust and stains enter the storage box 202 through the suction pipe 203, due to the presence of the cleaning water 4, the dust and stains will fall into the cleaning water 4 and cannot be sucked into the exhaust pipe 204 by the wind force at one end of the exhaust pipe 204, avoiding the situation where the dust and stains enter the storage box 202 and then are discharged out of the storage box 202 again through the exhaust pipe 204.

[0036] Further, to ensure that the dust and stains sucked into the storage box 202 will first adhere to the cleaning water 4, rather than being adsorbed into the exhaust pipe 204 due to the suction force of the exhaust pipe 204 at the other end of the storage box 202, the distance between the end where the suction pipe 203 is interconnected with the storage box 202 and the end where the exhaust pipe 204 is interconnected with the storage box 202 in this solution is greater than the distance between the end where the suction pipe 203 is interconnected with the storage box 202 and the highest liquid level of the cleaning water 4. In addition, in this solution, the end of the suction pipe 203 close to the storage box 202 is vertically interconnected with one end at the top of the storage box 202. Similarly, the end of the exhaust pipe 204 close to the storage box 202 is vertically interconnected with the other end at the top of the storage box 202. With such a setting, when the dust and stains are adsorbed from the suction pipe 203 into the storage box 202, the dust and stains will move under the action of a vertically downward force, that is, the force in the direction close to the cleaning water 4 on the dust and stains is greater than the suction force from the exhaust pipe 204. Also, since the distance between the dust and stains just entering the storage box 202 and the cleaning water 4 is less than the distance between them and the exhaust pipe 204, therefore, it can be ensured that the dust and stains sucked into the storage box 202 will first adhere to the cleaning water 4, rather than being adsorbed into the exhaust pipe 204 due to the suction force of the exhaust pipe 204 at the other end of the storage box 202.

[0037] It should also be noted that the height of the connection between the suction air duct 203 and the storage box 202 in this solution is lower than the height of the connection between the exhaust air duct 204 and the storage box 202. Such a setting can prevent dust and stains from being adsorbed into the exhaust air duct 204 due to the suction force of the exhaust air duct 204. At the same time, it can greatly increase the distance between the exhaust air duct 204 and the liquid level of the cleaning water 4, ensuring that the exhaust air duct 204 can absorb the gas in the storage box 202, and thus guaranteeing the suction force of the suction port 101.

[0038] It is worth noting that since the storage box 202 in this solution is respectively connected to the suction air duct 203 and the exhaust air duct 204, in order to prevent the cleaning water 4 located in the storage box 202 from flowing out of the cleaning housing 1 through the suction air duct 203 or the exhaust air duct 204 and affecting the adsorption effect of the adsorption component 2 on dust and stains, this solution also includes a liquid level sensor 5. The liquid level sensor 5 is arranged in the storage box 202, and the installation height of the liquid level sensor 5 is between the top surface in 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, and the liquid level sensor 5 is communicatively connected to the adsorption pump 201; when the amount of the cleaning water 4 filled in the storage box 202 is too much, or the device tilts during use, resulting in the liquid level of the cleaning water 4 rising and the cleaning water 4 coming into contact with the liquid level sensor 5, at this time, after the liquid level sensor 5 recognizes the rising of the liquid level of the cleaning 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 due to water ingress; on the other hand, it reminds the user that the liquid level of the cleaning water 4 is too high at this time, and the filling amount of the cleaning water 4 needs to be reduced or the use angle of the device needs to be adjusted.

[0039] Furthermore, this solution also includes a water isolation film 6. The water isolation film 6 is hermetically arranged at the connection between the exhaust air duct 204 and the storage box 202. Such a setting can prevent the cleaning water 4 located in the storage box 202 from flowing to the adsorption pump 201 through the exhaust air duct 204, resulting in damage to the adsorption pump 201; at the same time, the water isolation film 6 does not prevent the normal flow of air, ensuring that the adsorption component 2 of this solution can work properly.

[0040] According to the above embodiments, this solution needs to be placed on the desktop in order to normally adsorb dust and stains on the desktop; in addition, when the device is placed on the desktop, it is also necessary to ensure that the bottom surface of the device is parallel to the desktop without tilting, so as to ensure that the cleaning water 4 in the storage box 202 will not flow into the suction air pipe 203 through the communication port between the suction air pipe 203 and the storage box 202, affecting the effect of the storage box 202 in adsorbing dust and stains; based on this, in order to limit the use of the device, this solution further includes a pressing unit 7, and the pressing unit 7 includes a pressing module 701, a pressing rod 702 and a pressing spring 703. A pressing groove hole 104 is formed at the bottom of the cleaning housing 1. It should be noted that the bottom of the cleaning housing 1 in this solution is actually the bottom of the storage box 202, that is, the pressing groove hole 104 is provided at the bottom of the storage box 202; the pressing module 701 is arranged in the pressing groove hole 104, the pressing rod 702 is slidably arranged in the pressing groove hole 104, a pressing space is formed between the pressing rod 702 and the pressing groove hole 104, the pressing spring 703 is arranged in the pressing space, and both ends of the pressing spring 703 are respectively connected to the pressing rod 702 and the pressing groove hole 104. The pressing module 701 is respectively communicatively connected to the spraying pump 301 and the adsorption pump 201, and the pressing rod 702 can lock or release its pressing cooperation relationship with the pressing module 701; by providing the pressing unit 7, the acting force of the pressing spring 703 on the pressing rod 702 in the normal state is greater than the weight of the device itself. Therefore, the cleaning housing 1 in the normal state will be inclined. It should be noted that the inclination degree of the cleaning housing 1 in the normal state 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 this device, it is necessary to manually press the cleaning housing 1 so that the pressing rod 702 overcomes the acting force of the pressing spring 703 and slides in the direction of the pressing groove hole 104 until the pressing rod 702 and the pressing module 701 are in a pressing cooperation relationship. At this time, the pressing module 701 controls the spraying pump 301 and the adsorption pump 201 to work normally.

[0041] According to the above embodiments, it can be seen that during the use of the device, it is necessary to ensure that the bottom surface of the cleaning housing 1 is parallel to the desktop. If the device accidentally topples during use, the cleaning water 4 located in the storage box 202 will flow into the suction air duct 203, resulting in the residual cleaning water 4 in the suction air duct 203. At this time, when using the device to adsorb the dust on the desktop, the adsorbed dust will adhere to the inner wall of the suction air duct 203, affecting the subsequent cleaning effect of the desktop. Based on this, to solve this problem, a sealing assembly 8 is provided in this solution. The sealing assembly 8 includes a hinge plate 801, a hinge spring 802, and a driving unit 9. One end of the hinge plate 801 is hinged to the connection between the suction air duct 203 and the storage box 202. The hinge spring 802 is arranged in the storage box 202, and both ends of the hinge spring 802 are connected to the hinge plate 801 and the storage box 202 respectively. The driving unit 9 is arranged in the suction air duct 203. The driving unit 9 controls the closing of the hinge plate 801 by connecting with the hinge plate 801. Specifically, when the driving unit 9 applies a force to the hinge plate 801, the hinge plate 801 will rotate along the hinge end of its connection with the suction air duct 203 and the storage box 202, realizing the sealing fit between the hinge plate 801 and the connection between the suction air duct 203 and the storage box 202, preventing the water in the storage box 202 from flowing into the suction air duct 203. When the driving unit 9 releases the force applied to the hinge plate 801, the hinge plate 801 will re-release the sealing fit relationship with the connection between the suction air duct 203 and the storage box 202 due to the action of the hinge spring 802, enabling the adsorption assembly 2 to normally adsorb the dust and stains on the desktop into the storage box 202.

[0042] Furthermore, the driving unit 9 of the present solution includes a telescopic rod 901 with a hollow interior, a telescopic block 904, a telescopic spring 902, and a connecting rope 903. The telescopic rod 901 is disposed inside one end of the air suction pipe 203 close to the storage box 202. It should be noted that one end of the air suction pipe 203 close to the storage box 202 is vertically disposed at the top of the storage box 202. A telescopic slot hole is formed in the side wall of one end of the air suction pipe 203 close to the storage box 202. It should be noted that the axial direction of the telescopic slot hole is perpendicular to the axial direction of one end of the air suction pipe 203 close to the storage box 202. The telescopic rod 901 is disposed in the telescopic slot hole, and the axial direction of the telescopic rod 901 is consistent with the axial direction of the telescopic slot hole. The telescopic block 904 is slidably disposed inside the telescopic rod 901. There is a telescopic space between the telescopic block 904 and the bottom of the telescopic rod 901. The telescopic spring 902 is disposed in the telescopic space. The two ends of the telescopic spring 902 are respectively connected to the telescopic block 904 and the telescopic rod 901. The two ends of the connecting rope 903 are respectively connected to one end of the hinge plate 801 far from its hinge end and the telescopic block 904. By providing the driving unit 9, when the device accidentally falls during use, causing the cleaning housing 1 to tilt. At this time, the cleaning water 4 located in the storage box 202 will flow out through the gap at the connection between the hinge plate 801 and the air suction pipe 203 and the storage box 202. First, the cleaning water 4 will flow into the driving unit 9. It should be noted that since the cleaning housing 1 is tilted, at this time, the axial direction of the telescopic rod 901 is consistent with the direction of gravity. The cleaning water 4 will flow towards the bottom of the telescopic rod 901 under the action of gravity. As the weight of the cleaning water 4 flowing into the telescopic rod 901 increases, the telescopic block 904 will move towards the bottom of the telescopic rod 901, thereby pulling the connecting rope 903 and driving the hinge plate 801 to achieve a sealed fit at its connection with the air suction pipe 203 and the storage box 202. Similarly, when the device is manually repositioned, at this time, the axial direction of the telescopic rod 901 is perpendicular to the direction of gravity. The cleaning water 4 located inside the telescopic rod 901 will flow back onto the hinge plate 801 under the action of gravity. Since the connection between the hinge plate 801 and the air suction pipe 203 and the storage box 202 is still in a sealed state at this time, the cleaning water 4 will stay on the hinge plate 801. As the amount of cleaning water 4 flowing out to the telescopic rod 901 increases, the telescopic block 904 is reset under the action of the telescopic spring 902, thereby causing the acting force of the connecting rope 903 on the hinge plate 801 to disappear. At this time, the hinge plate 801 is reset under the action of the hinge spring 802, and the hinge plate 801 releases its sealed fit relationship with the connection between the air suction pipe 203 and the storage box 202. The cleaning water 4 located on the hinge plate 801 flows back into the storage box 202. It should be noted that to ensure that the cleaning water 4 located on the hinge plate 801 can smoothly flow back into the storage box 202, when the hinge plate 801 undergoes hinge rotation, it is always located inside the storage box 202.

[0043] In addition, it is also worth noting that in order to ensure that when the cleaning housing 1 is tilted, all the cleaning water 4 flowing out can flow into the telescopic rod 901, the width of the telescopic rod 901 in this solution is equal to the height dimension of the inner wall on one side of the air suction pipe 203, ensuring that all the cleaning water 4 flowing out can flow into the telescopic rod 901.
