Description

Technical Field

[0001] This utility model relates to the technical field of fabric cleaning machines, and in particular to a fabric cleaning device. Background Technology

[0002] Currently, in people's daily lives, most car seats, furniture sofas, carpets, etc. are cleaned and maintained using fabric cleaning machines.

[0003] In existing technologies, the cleaning head of a fabric cleaning machine only has a cleaning function and cannot be replaced with other functional attachments, resulting in a relatively limited functionality. Furthermore, in existing fabric cleaning machines, after wastewater is collected, it can only be poured out and cannot be further decomposed into clean water for reuse, which is not conducive to resource conservation. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing fabric cleaning machines where the cleaning head cannot be replaced with other functional accessories, and provides a fabric cleaning device in which the cleaning head can be replaced with other functional accessories.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fabric cleaning device, comprising:

[0007] main body;

[0008] An operating handle, one end of which is connected to the main body, and a replacement groove is provided on the side wall of the other end of the operating handle. A sliding groove is provided at the bottom of the replacement groove, and a connecting block is provided in the sliding groove. A rectangular hole is provided at the bottom of the sliding groove.

[0009] The replacement button is elastically slidably connected to the side wall of the operating handle, with one end of the replacement button located outside the operating handle and the other end located inside the operating handle.

[0010] A connecting rod is located inside the operating handle. One end of the connecting rod is bent and fixedly connected to the end of the replacement button located inside the operating handle. The other end of the connecting rod is bent and passes through the rectangular hole and is fixedly connected to one side of the connecting block. The top of the connecting block is away from the replacement button, and the bottom of the connecting block is close to the replacement button. A slot is provided on the top of the corresponding other side of the connecting block. The connecting block is elastically connected to the slide groove up and down by the connecting rod driven by the replacement button.

[0011] Several head attachments with different functions are provided. Each head attachment has a protruding locking block that matches a slot. The head attachment is detachably connected to the replacement slot via the locking block matching the slot. When replacing a head attachment, the operator slides the replacement button downwards. The replacement button, through a connecting rod, moves the connecting block in the slide downwards, causing the slot to move away from the top sidewall of the slide. Then, the corresponding head attachment is inserted into the slot via the locking block, and the replacement button is released. Under the elastic reset action, the replacement button moves the connecting block upwards via the connecting rod, fixing the locking block between the slot and the top sidewall of the slide. This allows the corresponding head attachment to be replaced within the replacement slot. The operation is simple, achieving the goal of replacing the cleaning head with other functional attachments, thus diversifying its functions and improving its practicality.

[0012] Preferably, the slot is V-shaped with acute angles formed by its two side walls. One side wall of the slot is parallel to the sliding direction of the connecting block, while the other side wall of the slot is inclined upwards. This design of the slot improves the connection strength between the head accessory and the replacement slot under elastic compression when the head accessory is matched with the locking block.

[0013] Preferably, the operating handle has a cavity in its side wall, and rectangular holes two parallel to the first rectangular hole are provided on both the front and rear sides of the cavity. A connecting shaft is located at the center of the replacement button. One end of the connecting shaft is fixedly connected to the replacement button, and the other end passes through the two rectangular holes two and is fixedly connected to the end of a connecting rod. The replacement button drives the connecting rod to slide up and down along the length of the rectangular holes two, connecting it to the side wall of the operating handle. A spring is provided inside the cavity, and the connecting shaft is elastically connected to the cavity vertically via the spring. The cavity facilitates the limiting installation of the spring; when the replacement button slides, it drives the connecting rod to slide via the connecting shaft, thus achieving synchronous sliding of the connecting block via the connecting rod, facilitating the disassembly and assembly of the locking block and the locking slot. The locking slot secures the locking block with a spring, enabling the replacement of several head accessories with different functions.

[0014] Preferably, the operating handle is equipped with a sewage pipe and a clean water pipe respectively. The other end of the operating handle is equipped with a suction nozzle that is connected to one end of the sewage pipe. The suction nozzle is located above the replacement slot, and the replacement button is located below the replacement slot. The suction nozzle, replacement slot, and replacement button are all located on the same side of the operating handle. The bottom of the replacement slot is fixed with a water outlet pipe that is connected to one end of the clean water pipe. The head accessory is equipped with a connector that matches the water outlet pipe. The head accessory is sealed to the water outlet pipe through the connector. The other ends of the sewage pipe and the other ends of the clean water pipe are both connected to the interior of the main body. Driven by corresponding components inside the main body, the main body is connected to the water outlet pipe via a clean water pipe, and then connected to the head accessory via a connector connected to the water outlet pipe to achieve the corresponding function. At the same time, the main body is connected to the suction nozzle via a wastewater pipe for corresponding operation. The head accessory is connected to the replacement slot via a matching locking block and locking groove, and the connector is connected to the water outlet pipe in the replacement slot to achieve the connection between the clean water pipe and the head accessory, facilitating the corresponding operation of the head accessory. The connection method between the water outlet pipe and the connector is generally a plug-in method for sealing connection, which is a common mating method, so it will not be described in detail here.

[0015] Preferably, a control panel is fixed to the top of the main body, several rollers are rotatably connected to the bottom of the main body, a water tank is provided on the side of the main body, and a water pump, a positive pressure air pump, a negative pressure air pump, and a circuit board are detachably connected inside the main body. The water pump, positive pressure air pump, and negative pressure air pump are all electrically connected to the control panel through the circuit board. An electrical socket is provided at the bottom of the replacement slot, located on the side of the slide. An electrical plug matching the electrical socket is fixed on the head accessory. A power cord is fixed on the main body. The head accessory is connected to the control panel through the electrical socket and the electrical plug, and then connected to the control panel through the circuit board. The control panel is electrically connected to the power cord via a circuit board. The water pump is connected to the clean water pipeline. Water in the water tank is pumped by the water pump and sequentially transported to the head accessory through the clean water pipeline and the outlet pipe. A suction pipe and a sewage collection pipe are fixed inside the water tank. Both the positive pressure pump and the negative pressure pump are connected to the sewage pipeline. Gas in the water tank is drawn in through the suction pipe under the positive pressure of the positive pressure pump and then sequentially sprayed out through the sewage pipeline and the nozzle. Sewage is drawn in through the nozzle under the negative pressure of the negative pressure pump and then sequentially collected in the water tank through the sewage pipeline and the sewage collection pipe. The power cord facilitates connection between the main unit and external wiring for power supply; the control panel allows the operator to control the start and stop of the dryer and select different functions; the head accessory is powered by plugging in the electrical socket and pins, and the corresponding functions can be activated through the control panel. The plug-in connection is a common method, so its specific structure will not be described here; water in the tank is pumped by the water pump and sequentially delivered to the head accessory through the clean water pipe and outlet pipe, facilitating the spraying of clean water onto the surface of the object to be treated, thus enabling further processing by the head accessory; gas in the tank is drawn in through the suction pipe by the positive pressure pump and then sequentially sprayed out through the wastewater pipe and nozzle, facilitating the drying of the object by the head accessory; wastewater is drawn in through the nozzle by the negative pressure pump and sequentially collected in the tank through the wastewater pipe and collection pipe, facilitating the treatment of wastewater on the surface of the object and maintaining environmental hygiene.

[0016] Preferably, a water pipe is provided on the bottom side wall of the main body. One end of the water pipe is fixedly connected to the main body, and the other end of the water pipe is fixed with a connecting shell. Two mutually isolated channels are provided inside the water pipe. One end of the operating handle is fixed with a connecting cover that matches the connecting shell. The connecting cover and the connecting shell are detachably connected and together form two mutually isolated filter chambers. Both the cleaning filter element and the filter element can be detachably connected to the filter chambers. The water tank is connected to one of the channels through a water pump. This channel is connected to the clean water pipeline through one of the filter chambers. The suction pipe and the sewage collection pipe are connected to the other channel after passing through a positive pressure air pump and a negative pressure air pump, respectively. This channel is connected to the sewage pipeline through the other filter chamber. The connecting cover and connecting shell can be detachably connected using snap-fit ​​or other methods, facilitating the cleaning and replacement of the filter element within the filter chamber. This is a common connection method and will not be elaborated upon here. When the cleaning filter element is installed in the filter chamber connected to the sewage pipe, it facilitates the purification of sewage sucked in by the suction nozzle into clean water, which is then collected back into the water tank, promoting water recycling and resource conservation. When the filter element is installed in the filter chamber connected to the clean water pipe, it facilitates the conversion of clean water in the water tank into a near-pure water flow that is sprayed onto the surface of the object to be treated, preventing scale buildup and further improving the cleaning effect.

[0017] Preferably, one side of the main body has a handheld slot, and the corresponding other side of the main body has a mounting slot that matches the water tank. The water tank is inserted into the mounting slot through its bottom. The bottom of the mounting slot has a clean water interface, a suction interface, and a wastewater interface. The clean water interface is connected to one of the channels via a water pump. The suction interface and the wastewater interface are respectively connected to the other channel via a positive pressure pump and a negative pressure pump. The top of the water tank is an open end covered with a cover, which is detachably connected to the water tank. One end of the suction pipe and one end of the wastewater collection pipe... Both ends are fixedly connected to the bottom of the water tank. The other end of the suction pipe and the other end of the sewage collection pipe are suspended in the top opening of the water tank. The side walls of the suction pipe and the sewage collection pipe are provided with through holes that communicate with the inside of the water tank. The through holes correspond to the top opening of the water tank. The bottom of the water tank is provided with three connection ports. Two of the connection ports are connected to the inside of the sewage collection pipe and the suction pipe, respectively, and are sealed and plugged into the sewage interface and the suction interface, respectively. The other connection port is connected to the inside of the water tank and is sealed and plugged into the clean water interface. The water tank is inserted into the mounting slot. This is a common fitting method, so it will not be described in detail here, to facilitate the installation and disassembly of the water tank. When the water tank is inserted into the mounting slot, the connection port is usually equipped with a one-way valve. When the three connection ports at the bottom of the water tank are sealed and inserted into the clean water interface, air intake interface and sewage interface on the mounting slot respectively, the one-way valve opens to facilitate the flow of water. This is a common fitting method, so it will not be described in detail here.

[0018] Preferably, several head accessories include a cleaning head, which includes a mounting base that matches the replacement slot. A locking block is fixed to the center of one side of the mounting base. The locking block, electrical pin, and connector are all located on the same side wall of the mounting base. The mounting base is detachably connected to the replacement slot via the locking block matching the slot. The opposite side of the mounting base is provided with a rotating head and a spray nozzle communicating with the connector. The mounting base contains a driver (not shown in the figure), which is electrically connected to the electrical pin. One side of the rotating head is rotatably connected to the mounting base under the drive of the driver. Several evenly distributed brushes are fixed on the opposite side of the rotating head. The suction nozzle is located above the rotating head, and the spray nozzle is located below the rotating head. When the cleaning function is needed, the operator inserts the cleaning head into the replacement slot using the replacement button, and simultaneously installs the cleaning filter cartridge into the filter chamber connected to the sewage pipe, and the filter cartridge into the filter chamber connected to the clean water pipe. After the operator presses the cleaning button on the control panel, the clean water in the tank flows to the clean water pipe under the pumping action of the water pump, and then sprays out through the spray nozzle on the cleaning head. The driver drives the rotating head to rotate, and the brush cleans the surface of the object to be treated. At the same time, the sewage is sucked in through the suction nozzle under the negative pressure of the negative pressure air pump, and then passes through the sewage pipe, the cleaning filter cartridge and the sewage collection pipe in sequence before being collected in the water tank. This facilitates the purification of sewage into clean water for recycling, which helps to save resources.

[0019] As another preferred embodiment, several head accessories also include an ironing head. One side of the ironing head has a protrusion that matches the replacement slot. The temperature adjustment knob is located on the side of the protrusion. A locking block is fixed to the center of the protrusion. The locking block, electrical pin, and connector are all located on the same side wall of the protrusion. A steam generator (not shown in the figure) is detachably connected inside the ironing head. The steam generator is electrically connected to the electrical pin. The opposite side of the ironing head has several evenly distributed steam holes. The connector communicates with the steam holes through the steam generator. When the ironing function is needed, the operator replaces the ironing head using the replacement button and installs it in the replacement slot. After the operator presses the ironing button on the control panel, the clean water in the water tank is filtered through a filter cartridge and converted into purified water by the water pump. This purified water is then transported to the steam generator through a clean water pipeline. The generated steam is ejected through the steam holes to achieve the ironing function. Depending on actual needs, a temperature adjustment knob can also be provided on one side of the ironing head to adjust the ironing temperature.

[0020] As another preferred embodiment, several head accessories also include a drying and sterilizing head. One side of the drying and sterilizing head is fixed with a protrusion that matches the replacement slot and an insertion port that matches the suction nozzle. A locking block is fixed to the center of the protrusion. The locking block, electrical pin, and insertion port are all located on the same side wall of the protrusion. On the opposite side of the drying and sterilizing head, several ultraviolet lamps, each electrically connected to the electrical pin, and several air vents connected to the insertion port are provided. The ultraviolet lamps are embedded in the side wall of the drying and sterilizing head. When the drying and sterilizing function is required, the operator replaces the drying and sterilizing head using the replacement button and installs it in the replacement slot. After the operator presses the drying button on the control panel, under the push of the positive pressure air pump, airflow is drawn into the sewage pipe through the suction pipe, finally enters the air vent through the suction nozzle, and is blown out from the air vent, thus drying the object to be treated. At the same time, the ultraviolet lamps sterilize the object to be treated.

[0021] The beneficial effects of this utility model are:

[0022] 1. Different functional head accessories can be replaced in the replacement slot using the replacement button. The operation is simple and achieves the purpose of replacing the cleaning head with other functional accessories, making its functions more diverse and improving its practicality;

[0023] 2. When the cleaning filter cartridge is installed in the filter chamber connected to the sewage pipe, it is easy to purify the sewage sucked in by the nozzle into clean water and return it to the water tank, which facilitates water recycling and helps to save resources.

[0024] 3. When the filter element is installed in the filter chamber connected to the clean water pipeline, it is easy to convert the clean water in the water tank into a water flow that is close to pure water and spray it onto the surface of the object to be treated. This avoids the formation of limescale and further improves the cleaning effect of the object to be treated. Attached Figure Description

[0053] like Figure 10 , Figure 11 and Figure 17 As shown, several head accessories 10 also include a drying and sterilizing head. One side of the drying and sterilizing head is fixed with a protrusion 50 that matches the replacement slot 3 and an insertion port 52 that matches the nozzle 18. A locking block 11 is fixed to the center of the protrusion 50. The locking block 11, the electrical plug 28 and the insertion port 20 are all located on the same side wall of the protrusion 50. On the other side of the drying and sterilizing head, there are several ultraviolet lamps 53 that are electrically connected to the electrical plug 28 and several air vents 54 that are connected to the insertion port 52. The ultraviolet lamps 53 are embedded in the side wall of the drying and sterilizing head.

[0054] In Example 1, when replacing the head accessory 10, the operator slides the replacement button 7 downwards. The replacement button 7 moves the connecting block 5 in the slide groove 4 downwards synchronously via the connecting rod 8, so that the slot 9 moves away from the top side wall of the slide groove 4. Then, the head accessory 10 with the corresponding function is inserted into the slot 9 via the locking block 11, and the replacement button 7 is released. Under the reset action of the spring 15, the replacement button 7 moves the connecting block 5 upwards via the connecting rod 8, so that the locking block 11 is fixed between the slot 9 and the top side wall of the slide groove 4. Thus, the head accessory 10 with the corresponding function can be replaced in the replacement slot 3. The operation is simple and achieves the purpose of replacing the cleaning head with other functional accessories, making its functions more diverse and improving its practicality.

[0055] When the head accessory 10 is installed into the replacement slot 3, it is powered by plugging in the electrical socket 27 and the electrical pin 28. The corresponding functions can be activated by operating the control panel 21. The connection between the electrical socket 27 and the electrical pin 28 is a common way of connecting, so its specific structure will not be described in detail here. Water in water tank 22 is pumped by water pump 23 and sequentially transported to head accessory 10 through clean water pipe 17 and outlet pipe 19, facilitating the spraying of clean water onto the surface of the object to be treated, thus facilitating further operation of the object by head accessory 10; gas in water tank 22 is drawn in through suction pipe 30 under the positive pressure of positive pressure air pump 24 and then sequentially sprayed out through sewage pipe 16 and nozzle 18, facilitating the drying of the object by head accessory 10; sewage is drawn in through nozzle 18 under the negative pressure of negative pressure air pump 25 and sequentially collected in water tank 22 through sewage pipe 16 and sewage collection pipe 31, facilitating the treatment of sewage on the surface of the object to be treated and maintaining environmental hygiene.

[0056] In Example 2, when the cleaning function is required, the operator installs the cleaning head into the replacement slot 3 via the replacement button 7 according to Example 1. Simultaneously, the cleaning filter element 36 is installed in the filter chamber connected to the sewage pipe 16, and the filter element 37 is installed in the filter chamber connected to the clean water pipe 17. After the operator presses the cleaning button on the control panel 21, the clean water in the water tank 22 flows to the clean water pipe 17 under the pumping action of the water pump 23, and is then sprayed out through the spray nozzle 48 on the cleaning head. The driver (not shown in the figure) drives the rotating head 47 to rotate, and the brush 49 scrubs the surface of the object to be treated. Simultaneously, under the negative pressure of the negative pressure air pump 25, the sewage is sucked in through the suction nozzle 18 and sequentially passes through the sewage pipe 16, the cleaning filter element 36, and the sewage collection pipe 31 before being collected in the water tank 22. The cleaning filter element 36 facilitates the purification of sewage into clean water for recycling, thus saving resources.

[0057] In Example 3, when the ironing function is required, the operator replaces the ironing head using the replacement button 7 according to Example 1 above and installs it in the replacement slot 3. After the operator presses the ironing button on the control panel 21, the clean water in the water tank 22 is converted into pure water by the filter element 37 under the pumping action of the water pump 23, and is transported to the steam generator through the clean water pipeline 17. The generated steam is sprayed out through several steam holes 51 to achieve the ironing function. According to actual needs, a temperature adjustment knob can also be provided on one side of the ironing head to adjust the ironing temperature.

[0058] In Example 4, when the drying and sterilization function is required, the operator replaces the drying and sterilization head by using the replacement button 7 according to Example 1 above, and installs it in the replacement slot 3. After the operator presses the drying button on the control panel 21, the airflow is drawn in through the suction pipe 30 and enters the sewage pipe 16 under the push of the positive pressure air pump 24. Finally, it enters the air outlet through the suction nozzle 18 and is blown out from the air outlet 54, which dries the object to be treated. At the same time, the ultraviolet lamp 53 sterilizes the object to be treated.
