[0025] It is worth mentioning that in the following embodiments, the decontamination device can clean textile articles in a home or an office. For example, it can decontaminate and clean beds, bed sheets, quilts, sofas, chairs, pillows, etc., and is not limited to the cleaning of the above-mentioned objects. In the following embodiments, the cleaning applied to a bed will be further elaborated.

[0026] As Figure 1 , Figure 2 and Figure 3 described, it is a decontamination device 10 in an embodiment, including a housing 100, an ultraviolet lamp 200 and a decontamination mechanism 300; an installation cavity is provided in the housing 100, and the ultraviolet lamp 200 and the decontamination mechanism 300 are both disposed in the installation cavity; the housing 100 has a decontamination surface 111, and a decontamination port 112 communicating with the installation cavity is opened on the decontamination surface 111. The ultraviolet lamp 200 and the decontamination mechanism 300 are disposed at a position in the installation cavity close to the decontamination port 112, and the ultraviolet lamp 200 and the decontamination mechanism 300 are oriented towards the decontamination port 112. The decontamination mechanism 300 includes a solution box 310, a liquid outlet head 320 and a cleaning member 330. The solution box 310 is communicated with the liquid outlet head 320 through a connecting pipe 321. The liquid outlet head 320 is used to spray a cleaning liquid outwards through the decontamination port 112, and the cleaning member 330 is movably disposed in the decontamination port 112 for cleaning the surface of an object.

[0027] In this embodiment, the decontamination surface 111 is used to fit onto the surface of the object to be cleaned and slide along the surface of the object to be cleaned. During the sliding process, the surface of the object to be cleaned is decontaminated. The solution box 310 is used to store the cleaning liquid, and the cleaning liquid also flows through the connecting pipe to the liquid outlet head 320, and flows out from the liquid outlet on the liquid outlet head 320 onto the surface of the object to be cleaned. The cleaning member 330 cooperates with the cleaning liquid to clean the surface of the object to be cleaned. Since the cleaning member 330 is driven to move within the decontamination port 112, the cleaning liquid is evenly smeared on the surface of the object to be cleaned through the movement, and the dirt on the object is removed. In this embodiment, a valve is provided on the connecting pipe, and the valve is electrically connected to the switch 410 on the housing 100. In this way, by controlling the opening of the valve, the connecting pipe can be connected, and the cleaning liquid in the solution box 310 can be transported to the liquid outlet head 320.

[0028] The moving mode of the cleaning member can be linear reciprocating motion or rotation. Through the movement of the cleaning member, the surface of the object to be cleaned is rubbed, and the cleaning liquid is stirred evenly, so as to realize the cleaning and decontamination of the surface of the object to be cleaned. The cleaning liquid is a dry cleaning solution, and the dry cleaning solution includes perchloroethylene. In this way, dry cleaning of the surface of the object to be cleaned can be realized without rinsing with water. It is worth mentioning that the object to be cleaned includes but is not limited to beds, bed sheets, quilt covers, sofas, etc., and no redundant description is given in this embodiment.

[0029] In addition, the ultraviolet lamp 200 irradiates ultraviolet light onto the surface of the object to be cleaned through the decontamination port 112. Through the irradiation of the ultraviolet lamp 200, the surface of the object to be cleaned can be effectively sterilized and disinfected, making the decontamination and deodorization effects better.

[0030] In the above embodiment, by arranging the liquid outlet head 320 and the cleaning member 330 in the housing 100, the household cleaning device can spray the cleaning liquid on the surface of the household, and cooperate with the movement of the cleaning member 330 to clean the surface of the household, making the cleaning effect of the household such as the bed better, and making the deodorization and decontamination effects better. In addition, through the irradiation of the ultraviolet lamp 200, the surface of the object to be cleaned can be effectively sterilized and disinfected, making the decontamination and deodorization effects better.

[0031] In order to recover the cleaning liquid remaining in the liquid outlet head 320 that has not been sprayed, in one embodiment, as shown in FIG. 2, the decontamination mechanism 300 further includes a self-priming pump 360. A partition is provided in the solution box 310, and the partition divides the solution box 310 into a solution chamber 311 and a recovery chamber 312. The solution chamber 311 is communicated with the liquid outlet head 320 through the connecting pipe. The first end of the self-priming pump 360 is communicated with the liquid outlet head 320 through a recovery pipe, and the second end of the self-priming pump 360 is communicated with the recovery chamber.

[0032] In this embodiment, the solution box 310 is divided into two independent chambers. One is the solution chamber 311 for storing unused cleaning liquid, and the other is the recycling chamber 312 for recycling and storing the recycled cleaning liquid. In this way, when there is cleaning liquid remaining in the liquid outlet head 320 after cleaning, under the action of the self-priming pump 360, the cleaning liquid remaining in the liquid outlet head 320 and the connecting pipe is sucked into the recycling pipe and then transported to the recycling chamber, realizing the recycling of the cleaning liquid and effectively avoiding the waste of the cleaning liquid.

[0033] In order to achieve efficient cleaning of the bed, in one embodiment, please refer to Figure 3 , the liquid outlet head 320 is a shower head, and the cleaning member 330 is a plurality of hoses arranged on the shower head.

[0034] In this embodiment, the decontamination mechanism 300 includes a plurality of drive motors and a plurality of shower heads. Each drive motor is drivingly connected to a shower head, and the drive motor is used to drive the shower head to rotate. In this way, the rotation of the shower head will drive the hoses to rotate. The hoses are soft rubber hoses, and the rotation of the plurality of soft rubber hoses, in cooperation with the cleaning liquid, rubs the surface of the bed to achieve the cleaning of the bed. Due to the soft characteristics of the hoses, they are easy to deform and have elasticity, which can effectively increase the friction frequency and friction force of the object to be cleaned, and cooperate with the cleaning liquid to play a good cleaning role on the bed.

[0035] In one embodiment, a pipe is provided in each of the hoses, and the shower head is provided with a plurality of liquid outlet ports, and each liquid outlet port is communicated with one of the pipes.

[0036] In this embodiment, the pipe of each hose is communicated with a liquid outlet port, so that the cleaning liquid in the shower head can be evenly sprayed onto the bed through each hose, thereby making the cleaning effect better. In addition, the hoses not only play a role in cleaning, but also play a role in transporting the cleaning liquid, making the cleaning liquid more evenly and closer to the end of the hose for spraying, further improving the cleaning efficiency.

[0037] In one embodiment, as Figure 2 shown, the decontamination mechanism 300 further includes a first blower 340. The first blower 340 is disposed in the housing 100, and the first blower 340 is communicated with the decontamination port 112 through an air duct 103.

[0038] In this embodiment, the first blower 340 is used to blow air to the decontamination port 112 through the air duct 103. In this way, by driving the rapid circulation of air by the first blower 340, the cleaning liquid coated on the surface of the object to be cleaned can be quickly dried, accelerating the evaporation of the cleaning liquid, thereby improving the cleaning efficiency.

[0039] In one embodiment, as Figure 2As shown, the decontamination mechanism 300 further includes a heating component 350, and the heating component 350 is disposed in the air duct 103.

[0040] In this embodiment, the heating component 350 includes a heating wire, and the heating wire is disposed between the first blower 340 and the decontamination port 112, that is, the heating wire is disposed on the path where the first blower 340 blows air towards the decontamination port 112. In this way, after the heating wire is powered on, it heats up, causing the air to be heated. The first blower 340 blows the hot air towards the surface of the object to be cleaned, which can effectively accelerate the drying of the cleaning liquid on the surface of the object to be cleaned.

[0041] In one embodiment, please refer to Figure 1 and Figure 2 , a plurality of heat dissipation holes 113 communicating with the installation cavity are formed in one side of the housing 100 facing away from the decontamination surface 111.

[0042] In this embodiment, a plurality of heat dissipation holes 113 are formed in the back surface of the housing 100, and the heat dissipation holes 113 are aligned with the ultraviolet lamp 200 and the decontamination port 112. In this way, the hot air blown out by the first blower 340 after heating can also be dissipated through the heat dissipation holes 113, preventing heat from accumulating on the surface of the object to be cleaned and providing an outlet for the air circulation, making the air circulation smoother.

[0043] In one embodiment, the decontamination device 10 further includes a dust suction mechanism. The installation cavity includes a first installation sub-cavity 101 and a second installation sub-cavity 102 that are isolated from each other. The first installation sub-cavity 101 communicates with the decontamination port 112. The ultraviolet lamp 200 and the decontamination mechanism 300 are both disposed in the first installation sub-cavity 101. A dust suction port 105 communicating with the second installation sub-cavity 102 is further formed in the decontamination surface 111. The dust suction mechanism is disposed in the second installation sub-cavity 102 and is oriented towards the dust suction port 105.

[0044] In this embodiment, the ultraviolet lamp 200, the liquid outlet head 320, and the cleaning member 330 are disposed in the first installation sub-cavity 101. In this embodiment, the decontamination device 10 can also suck dust from the surface of the object to be cleaned. The first installation sub-cavity 101 and the second installation sub-cavity 102 that are independent and non-communicating with each other are provided in the housing 100, so that the decontamination mechanism 300 and the dust suction mechanism are respectively placed in different chambers, which is conducive to separate decontamination cleaning and dust suction. During use, first, the bed is vacuumed, then the cleaning liquid is sprayed on the bed for decontamination, and ultraviolet light is irradiated. In this way, not only can the dust on the surface of the bed be effectively removed, but also the bed can be effectively cleaned and the odor can be removed.

[0045] In order to reasonably arrange each mechanism and make the decontamination device 10 easy to operate, in one embodiment, the housing 100 includes a first sub-housing 110 and a second sub-housing 120. The first sub-housing 110 is connected to the second sub-housing 120. The first installation sub-cavity 101 and the second installation sub-cavity 102 are arranged in the first sub-housing 110. The second sub-housing 120 is arranged on the side of the first sub-housing 110 facing away from the decontamination surface 111. A blowing cavity 121 is arranged in the second sub-housing 120. The blowing cavity 121 is communicated with the first installation sub-cavity 101 through an air duct 103. The decontamination mechanism 300 further includes a first blower 340 and a heating component 350. The first blower 340 is arranged in the blowing cavity 121, and the first blower 340 is communicated with the decontamination port 112 through the air duct 103. The heating component 350 is arranged in the air duct 103.

[0046] In this embodiment, the first sub-housing 110 is arranged in a flat shape. The bottom surface of the first sub-housing 110 is the decontamination surface 111. The side of the first sub-housing 110 opposite to the decontamination surface 111 is the top surface. The top surface is connected to the second sub-housing 120. Both the decontamination surface 111 and the top surface of the first sub-housing 110 are arranged as flat surfaces. The two sides of the first sub-housing 110 are arranged as arc surfaces. The first sub-housing 110 and the second sub-housing 120 are respectively provided with air ducts 103 that communicate with each other, so that the blowing cavity 121 is communicated with the first installation sub-cavity 101 through the air duct 103. A baffle is arranged in the first sub-housing 110. The baffle divides the installation cavity in the first sub-housing 110 into a first installation sub-cavity 101 and a second installation sub-cavity 102. By arranging the first sub-housing 110 in a flat shape, it is beneficial to increase the contact area between the decontamination surface 111 and the object to be cleaned, so that the decontamination surface 111 better fits on the surface of the object to be cleaned, and it is beneficial to place the decontamination device 10.

[0047] The second sub-housing 120 is arranged in a cylindrical shape. The solution box 310 is connected to the second sub-housing 120. The self-priming pump 360, the heating component 350 and the first blower 340 are arranged in the blowing cavity 121. By arranging the second sub-housing 120 in a cylindrical shape, the volume of the blowing cavity 121 is relatively large and matches the shape of the first blower 340, which is beneficial to installing the heating component 350 and the first blower 340.

[0048] In addition, a handle 400 is arranged on the second sub-housing 120. The handle 400 is convenient for the user to hold and operate. A switch 410 is arranged on the handle 400. The switch 410 is electrically connected to the first blower 340, the drive motor, the heating component 350 and the self-priming pump 360 respectively through a control main board. The switch 410 is used to control the operation of the first blower 340, the drive motor, the heating component 350 and the self-priming pump 360.

[0049] In one embodiment, a flow guide plate 150 is disposed in the installation cavity. The flow guide plate 150 is bent and is located in the air duct 103. The flow guide plate 150 is used to direct air to the main board in the decontamination device 10.

[0050] In this embodiment, due to the arrangement of the flow guide plate 150, when the heating component 350 is not working and the first fan 340 is working, the air flowing in the air duct 103 can flow along the flow guide plate, so that the air can take away the heat of the main board, which can play a good heat conduction role and avoid overheating of the main board.

[0051] In order to achieve better dust suction effect, in one embodiment, the dust suction mechanism includes a diversion plate 510, a second fan 520 and a dust suction box 530. The diversion plate 510 is bent. One end of the diversion plate 510 is disposed on one side of the dust suction port 105. The other end of the diversion plate 510 is connected to the dust suction box 530. The second fan 520 is disposed between the dust suction port 105 and the dust suction box 530 and is oriented towards the dust suction port 105. The dust suction box 530 has an inlet that faces the diversion plate 510.

[0052] In this embodiment, the second fan 520 is an exhaust fan, which is used to draw air in the direction of the dust suction port 105 and send the drawn air into the dust suction box 530. A dust storage cavity is disposed in the dust suction box 530 for storing dust. The diversion plate 510 is bent, which is beneficial to guiding the air and dust drawn by the second fan 520 to the dust suction box 530. In this way, the dust suction effect can be better.

[0053] In one embodiment, the diversion plate 510 includes a diversion plate body, a support plate and a connecting plate. One side of the diversion plate body is connected to one side of the support plate. The other side of the support plate is connected to one side of the connecting plate. The other side of the connecting plate is connected to the other side of the diversion plate body. The diversion plate body, the support plate and the connecting plate are connected in sequence, and a dust suction cavity is formed inside. The support plate is connected to the first sub-shell 110, and the dust suction port 105 is opened on the support plate. The second fan 520 is disposed in the dust suction cavity. The diversion plate body is bent. The connecting plate is recessed inward on the outer side of the dust suction cavity to form a mounting portion. The dust suction box 530 is disposed on the mounting portion. The connecting plate is provided with a dust suction hole, and the dust suction hole is aligned and communicated with the inlet of the dust suction box 530. In this way, when the first fan 340 located in the dust suction cavity works, the dust on the surface of the object to be cleaned can be sucked in, and the air and dust can flow along the diversion plate 510 to the dust suction hole, and then the dust enters the dust suction box 530.

[0054] The above-mentioned decontamination device 10 is configured with a liquid outlet head 320 and a cleaning member 330 inside the housing 100, enabling the household decontamination device to spray the cleaning liquid onto the surface of household items and, in cooperation with the movement of the cleaning member 330, clean the surface of household items, thereby achieving a better cleaning effect on household items such as beds, and a better effect of removing odors and dirt.

[0055] In one embodiment, the decontamination device has two working modes. One is the ordinary dust suction and ultraviolet sterilization mode; the other is the decontamination and drying mode. By setting up a double-chamber structure solution box and containing dry cleaning solution such as perchloroethylene inside, it can quickly and safely clean local dirty beddings or clothes. At the same time, an axial flow fan and an electric heater are provided inside the second sub-housing, which can blow-dry the cleaned surface, and avoid the problem of overheating and burning the circuit board due to poor ventilation when blowing hot air, ensuring the reliability and safety of the product.

[0056] The device mainly consists of two major components: a fan compartment and a dust suction compartment 2, and specifically, the vacuum cleaner can be modularly divided.

[0057] As Figure 4 shown, after the push-button switch activates the power supply and the dust suction mode is selected, the second fan starts. The second fan is a downward dust suction fan, and a negative pressure is formed in the dust storage chamber. Dust particles, cotton fluffs, hair and other sundries on the surface of the item are sucked into the dust box from the dust suction port. The dust box can be removed for manual cleaning. At the same time, the ultraviolet lamp can be turned on to sterilize the cleaned surface.

[0058] In addition, the user can also select the decontamination mode. If the above-mentioned push-button switch also selects the decontamination mode, the quantitative dry cleaning liquid in the solution box flows through the hose in the middle of the shower head to the surface to be cleaned. Subsequently, the drive motor starts, driving the shower head to rotate for the stirring cleaning mode. Through the dry cleaning principle, the chemical solvent of the dry cleaning liquid penetrates, dissolves, and dilutes to clean the item. Subsequently, the self-priming pump is started to recover the waste solution remaining in the shower head and the hose on the shower head, completing the cleaning mode.

[0059] After the cleaning is completed, the first fan is controlled to start, and the heating component is controlled to be energized for heating, and hot air is blown out from the air duct to blow-dry the wet surface of the item, completing the decontamination mode.

[0060] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0061] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
