Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, specifically to a cleaning device and its air duct switching system. Background Technology

[0002] In daily life, fabric items such as sofas, carpets, curtains, and leather chairs accumulate dirt on their surfaces after prolonged use. Users often prefer to purchase fabric cleaning machines to remove this dirt. Specifically, fabric cleaning machines typically have a handheld cleaning attachment, usually equipped with a water spray nozzle and a suction nozzle. The water spray nozzle sprays clean water or a cleaning solution containing detergent onto the surface dirt of the fabric, and the suction nozzle removes the sprayed liquid and any remaining dirt, thus achieving the purpose of cleaning the fabric.

[0003] Current fabric cleaning machines typically only offer cleaning capabilities and lack drying functions, requiring users to spend a considerable amount of time air-drying the fabric after washing, resulting in a poor user experience. While a few fabric cleaning machines on the market are equipped with drying functions, these require an additional fan to achieve this, making the equipment very heavy and significantly increasing power consumption.

[0004] Meanwhile, the drying hot air of the fabric cleaning machine is mainly blown out from the air outlet on the accessories. However, the area from which the hot air is blown out on the drying accessories is relatively small, which results in excessively long drying time when drying large wet areas, leading to a poor user experience. Utility Model Content

[0005] This disclosure provides a cleaning device and its air duct switching system to address the problems existing in the prior art.

[0006] According to a first aspect of this disclosure, a cleaning device is provided, comprising:

[0007] The machine body is equipped with a recycling space and a clean water space.

[0008] The main motor is mounted on the machine body and is configured to have an air inlet and an air outlet;

[0009] A drying air duct is provided on the machine body and modified to connect with the air outlet of the main motor. A heating element is provided inside the drying air duct.

[0010] The drying duct has an outlet end adjacent to the side wall of the machine body. The drying duct is located downstream of the heating element and is configured to penetrate the wall of the drying duct to form an air outlet that communicates with the outside. A baffle is movably installed in the drying duct and is configured to close or open the outlet end of the drying duct.

[0011] A drying accessory, the drying accessory including a plug assembly configured to extend from the outlet end into the drying duct and push a baffle to open the outlet end of the drying duct and close the air outlet.

[0012] According to a second aspect of this disclosure, a duct switching system for a cleaning device is also provided, comprising:

[0013] Main motor;

[0014] Exhaust gas discharge channel;

[0015] A drying duct; the drying duct has an outlet end and an air outlet adjacent to the outlet end and penetrating the wall of the drying duct; a baffle is movably disposed in the drying duct, the baffle being configured to close or open the outlet end; when the baffle is configured to close the outlet end, the airflow in the drying duct is configured to be discharged through the air outlet; and when a drying accessory pushes the baffle and extends it from the outlet end to open the outlet end of the drying duct and close the air outlet, the airflow in the drying duct is configured to be discharged through the drying accessory.

[0016] A reversing assembly, which can selectively open the passage between the main motor and the exhaust gas discharge channel, or selectively open the passage between the main motor and the drying air duct.

[0017] One beneficial effect of this disclosure is that the main motor has an air inlet and an air outlet. When the main motor is working, the air inlet can draw air to create a negative pressure environment in the recovery space to achieve the cleaning function; the air drawn out by the main motor can be discharged from the air outlet and flow into the drying air duct to be heated to form hot air, thereby achieving the drying function. Specifically, without the drying accessories installed, hot air can be blown out from the air outlet to dry a large area of ​​the work surface; with the drying accessories installed, hot air can be blown out from the drying accessories to dry a localized, targeted area of ​​the work surface. This disclosure enables the cleaning equipment to simultaneously perform cleaning and drying functions by setting up a single main motor, without significantly increasing the weight and power consumption of the cleaning equipment, thereby improving the user experience.

[0018] Other features and advantages of this disclosure will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings. Attached Figure Description

[0038] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0039] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0040] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0042] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0043] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0044] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0045] This disclosure provides a cleaning device, which can be various types of cleaning equipment such as fabric cleaning machines, handheld floor scrubbers, and robot vacuum cleaners; this disclosure does not limit the type of cleaning device. This embodiment uses a fabric cleaning machine as an example for illustration.

[0046] Fabric cleaning machines are used to clean fabric items such as sofas, carpets, curtains, and leather chairs. After prolonged use, these fabric items accumulate dirt and grime, which the cleaning machine can remove. However, existing fabric cleaning machines typically only clean and lack drying capabilities, requiring users to leave them to air dry for extended periods after washing, resulting in a poor user experience. To address this issue, the cleaning equipment disclosed herein includes a drying function.

[0047] refer to Figures 1 to 4 The cleaning equipment includes a main body (1), a main motor (2), a drying duct (3), and drying accessories (4). The main body (1) is the core of the cleaning equipment, containing various functional components and piping. For example... Figure 1 As shown, a carrying handle 18 can be provided on the top of the body 1. Users can lift the cleaning equipment by holding the carrying handle 18, thereby moving the cleaning equipment to a more convenient position for operation.

[0048] refer to Figure 4 The machine body 1 is provided with a recovery space 11 and a clean water space 12. The recovery space 11 is used to temporarily store dirt generated during cleaning, and the clean water space 12 is used to store clean liquids such as clean water and / or cleaning solution. The liquid in the clean water space 12 can be sprayed onto the work surface to be cleaned to wet the work surface and enhance the cleaning effect.

[0049] In one embodiment of this disclosure, reference is made to Figure 1The cleaning equipment includes a cleaning component 6, which may include a cleaning tube 61, a cleaning brush head 62, and a cleaning handheld part 63. The cleaning tube 61 is used to connect to the main body 1, such as... Figure 2 As shown, a connection port 17 is provided on the body 1. The cleaning tube 61 can extend into the body 1 through the connection port 17, thereby connecting with the recycling space 11 and the clean water space 12 respectively. The cleaning brush head 62 is connected to the free end of the cleaning tube 61 through the cleaning handle 63. When cleaning, the user holds the cleaning handle 63 to move the cleaning brush head 62 on the working surface for precise cleaning of dirt on fabrics.

[0050] The cleaning tube 61 can be constructed as a flexible, extendable tube that can be bent freely. During cleaning, the user moves the cleaning brush head 62, causing the cleaning tube 61 to deform naturally. A longer cleaning tube 61 can cover a larger cleaning area, reducing the need for the user to frequently move the cleaning equipment. In one specific embodiment of this disclosure, such as... Figure 1 As shown, a storage rack 19 can be provided on the side wall of the body 1. After the cleaning work is completed, the user can coil the cleaning tube 61 on the outside of the body 1. The storage rack 19 can support part of the cleaning tube 61, thus making it easy to store.

[0051] The cleaning brush head 62 can be equipped with bristles that can rub against the work surface, thereby improving the cleaning effect. In addition, the cleaning brush head 62 can also be equipped with a water spray nozzle and a suction port. The water spray nozzle can be connected to the clean water space 12 through the cleaning pipe 61, and the suction port can be connected to the recycling space 11 through the cleaning pipe 61. During cleaning, the user can spray cleaning liquid from the clean water space 12 onto the surface dirt of the fabric through the water spray nozzle. The cleaning brush head 62 then moves back and forth over the dirt area, brushing off the dirt with the bristles. Under the negative pressure of the suction port, the remaining liquid and dirt are sucked into the recycling space 11.

[0052] refer to Figure 4 The main motor 2 is mounted on the body 1 and is configured to have an air inlet 201 and an air outlet 202. The main motor 2 is located inside the body 1 and can be separated from the liquid storage recovery space 11 and the clean water space 12, thus helping to balance the overall center of gravity of the cleaning equipment. When the main motor 2 is turned on, it draws in air through the air inlet 201 and discharges this air through the air outlet 202.

[0053] The drying air duct 3 is installed on the machine body 1 and is modified to connect with the air outlet 202 of the main motor 2. A heating element 31 is installed inside the drying air duct 3. The heating element 31 can be a PTC heating element. The gas from the air outlet 202 of the main motor 2 can be blown into the drying air duct 3 and heated into hot air as it flows through the heating element 31. The hot air can be used for drying.

[0054] In one embodiment of this disclosure, the drying duct 3 is configured to be located below the main motor 2, and the air inlet 201 and air outlet 202 of the main motor 2 are configured to open downwards. A negative pressure pipe 51 and a positive pressure pipe 52 are provided between the main motor 2 and the drying duct 3. The air inlet 201 of the main motor 2 is configured to be connected to the recovery space 11 through the negative pressure pipe 51, and the air outlet 202 of the main motor 2 is configured to be connected to the drying duct 3 through the positive pressure pipe 52.

[0055] Specifically, refer to Figure 4 , Figure 8 and Figure 9 A motor support 21 can be provided at the bottom of the main motor 2, and the motor support 21 mounts the main motor 2 and positions it above the drying air duct 3. For example... Figure 9 As shown, the top of the motor support 21 has an open structure. Since the air inlet 201 and air outlet 202 of the main motor 2 are constructed to open downwards, the air inlet 201 and air outlet 202 of the main motor 2 can be connected to the internal cavity of the motor support 21.

[0056] The side wall of the motor support 21 is provided with an air inlet 211 for connecting to the negative pressure pipe 51. The air inlet 201 of the main motor 2 is connected to the recovery space 11 through the air inlet 211 and the negative pressure pipe 51, thereby creating a negative pressure environment in the recovery space 11 to provide sufficient suction for the suction port of the cleaning brush head 62. The side wall of the motor support 21 is also provided with a positive pressure pipe 52. The air outlet 202 of the main motor 2 is connected to the drying air duct 3 through the positive pressure pipe 52, thereby providing air to the drying air duct 3 as a drying air source.

[0057] Furthermore, in one specific embodiment of this disclosure, such as Figure 8 As shown, a housing chamber for accommodating the electromagnetic pump 22 can also be provided on the side wall of the motor support 21. The electromagnetic pump 22 can be used to pump liquid in the clean water space 12 to the spray nozzle of the cleaning brush head 62. In this disclosure, the electromagnetic pump 22 is installed close to the main motor 2, thereby integrating the main electrical components inside the body 1 and optimizing the internal structural layout of the body 1. At the same time, the housing chamber accommodating the electromagnetic pump 22 is connected to the chamber accommodating the main motor 2, thereby using the airflow generated by the main motor to carry away the heat dissipated by the electromagnetic pump in the housing chamber, preventing the electromagnetic pump from being damaged due to continuous heat generation during operation in the sealed housing chamber.

[0058] refer to Figure 4 and Figure 5 The drying duct 3 has an outlet end 32 adjacent to the side wall of the machine body 1. The drying duct 3, located downstream of the heating element 31, is configured to penetrate the wall of the drying duct 3 to form an air outlet 33 communicating with the outside. In a specific embodiment of this disclosure, the air outlet 33 can be located on the bottom wall of the drying duct 3, and the outlet end 32 can be located on the side wall of the drying duct 3. It is understood that both the outlet end 32 and the air outlet 33 are located downstream of the heating element 31 in the drying duct 3, thereby ensuring that the gas flowing to the outlet end 32 and the air outlet 33 is hot air that can be directly used for drying. A baffle 34 is movably disposed in the drying duct 3, and the baffle 34 is configured to close or open the outlet end 32. The baffle 34 can be hinged to the machine body 1, and in its natural state, the baffle 34 can move to the position of closing the outlet end 32 under its own weight.

[0059] With the air outlet 33 open and the outlet end 32 closed, the gas in the drying air duct 3 can be blown directly from the bottom of the body 1 through the air outlet 33, achieving drying of large-area wet areas. At this time, the user can place the entire cleaning device on the work surface to be dried and aim the air outlet 33 at the area to be dried. Then the user can continue to clean other areas. When the main motor 2 is working, it draws in the recovery space 11 to create a negative pressure environment, thereby providing sufficient suction for the suction port of the cleaning brush head 62, while supplying air to the drying air duct 3. The hot air formed by the heating element 31 can be blown directly from the air outlet 33 at the bottom of the body 1 to the area to be dried, thereby achieving the drying function. This disclosure realizes that by setting a main motor 2, the cleaning device can realize both cleaning and drying functions at the same time, without significantly increasing the weight and power consumption of the cleaning device, avoiding the operational complexity caused by the user having to use cleaning and drying accessories at the same time, thereby improving the user experience.

[0060] refer to Figure 2 and Figure 3 The cleaning equipment includes a drying accessory 4 that is detachable from the main body 1. The drying accessory 4 includes a plug assembly 41, a drying tube 42, and a drying head 43. The plug assembly 41 is configured to extend from the outlet end 32 into the drying duct 3 and push a baffle to open the outlet end 32 of the drying duct 3 and close the air outlet 33.

[0061] In one specific embodiment of this disclosure, the air outlet 33 is closed by blocking the air outlet 33 through the outer wall of the plug assembly 41. Specifically, during insertion, the plug assembly 41 pushes the baffle 34 to flip, thereby allowing the plug assembly 41 to extend from the outlet end 32 into the drying duct 3, and sealing the air outlet 33 through the side wall of the plug assembly 41, thus connecting the drying duct 3 through the outlet end 32. One end of the plug assembly 41 is connected to the drying head 43 through the drying tube 42, and the other end is inserted into the machine body 1 from the outlet end 32. During insertion, the plug assembly 41 can push the baffle 34 to flip up, thereby allowing it to be inserted into the drying duct 3.

[0062] When inserted, the outer wall of the plug assembly 41 fits tightly against the inner wall of the drying duct 3 near the outlet end 32, thereby blocking the air outlet 33 located on the bottom wall of the drying duct 3 and sealing it. At this time, the hot air in the drying duct 3 cannot be discharged through the air outlet 33, but continues to flow into the plug assembly 41 along the extension direction of the drying duct 3. The plug assembly 41 can have a shape adapted to the outlet end 32, and a sealing structure can be provided at the connection point after insertion, ensuring that there are no air leaks between the outlet end 32 and the plug assembly 41. All the hot air in the drying duct 3 can flow through the plug assembly 41 to the drying head 43, allowing the user to flexibly handle areas where drying through the air outlet 33 is inconvenient.

[0063] In one specific embodiment of this disclosure, the air outlet 33 is configured to be located adjacent to the outlet end 32, thereby shortening the length of the plug assembly 41 inserted into the drying air duct 3. The plug assembly 41 only needs to be inserted for a very short time to block the air outlet 33, thereby reducing the difficulty for users to install the plug assembly 41 and improving the user experience. Furthermore, the part of the plug assembly 41 inserted into the drying air duct 3 is flat, and the width of the top and bottom walls is greater than the height of its side walls, thereby ensuring that the plug assembly 41 can seal the air outlet 33.

[0064] like Figure 3 As shown, a drying handle 431 can be provided on the top of the drying head 43, allowing the user to manually control the movement of the drying head 43 on the damp working surface to be dried by holding the drying handle 431. Multiple drying air vents 432 are provided on the bottom surface of the drying head 43, and these vents are connected to the drying duct 3 via a drying pipe 42 and a plug assembly 41. Hot air from the drying duct 3 can be evenly blown out from the multiple drying air vents 432. The user can position the bottom surface of the drying head 43 towards the working surface to be dried, allowing the hot air from the drying air vents 432 to dry it.

[0065] Similar to the aforementioned cleaning tube 61, the drying tube 42 can also be constructed as a flexible tube that can be bent freely. During the process of the user moving the drying head 43 for localized drying, the drying tube 42 can naturally deform. The longer drying tube 42 can radiate a larger drying area and drying areas in different directions, such as the side area of ​​a fabric sofa, so that the user does not have to move the cleaning equipment frequently during the drying process.

[0066] Without the drying accessory 4 installed, hot air can be blown out from the air outlet 33 to dry a large area of ​​the work surface. With the drying accessory 4 installed, hot air can be blown out from the drying accessory 4 to dry specific areas of the work surface. Thus, users can choose whether to install the drying accessory 4 based on the specific location and size of the area to be dried, thereby improving the user experience. For example, when the work surface to be dried is a curtain, the air outlet 33 at the bottom of the cleaning device is insufficient to dry a vertically positioned surface; therefore, the user can choose to install the drying accessory 4 and dry it manually. When the work surface to be dried is a carpet, and the area to be dried is large, the cleaning device can be placed directly on the carpet. While cleaning with the cleaning accessories, the hot air blown from the bottom of the cleaning device dries the previously cleaned damp areas, thus drying the carpet over a large area through the air outlet 33 while shortening the overall cleaning time.

[0067] In one embodiment of this disclosure, reference is made to Figure 4 , Figure 11 and Figure 12 The bottom of the body 1 is provided with a second groove 102 formed by an upward indentation. The second groove 102 is configured to be isolated from the air outlet 33 by a partition; the second groove 102 is connected to the air outlet 33 through a plurality of through openings 103 provided in the partition.

[0068] Specifically, the second groove 102 can be formed on the outer wall of the bottom shell 10 on the side away from the air outlet 33, and the side wall of the bottom shell 10 is constructed to be concave upward to form the second groove 102. In this embodiment, the partition is the wall surface of the bottom shell 10, and the second groove 102 is isolated from the air outlet 33 through the wall surface of the bottom shell 10. Multiple openings 103 penetrate the wall surface of the bottom shell 10, thereby connecting the second groove 102 and the air outlet 33 through the multiple openings 103. This allows the airflow blown out of the air outlet 33 to flow into the second groove 102 through the multiple openings 103 and finally dissipate outward from the second groove 102. By setting the second groove 102, the area on the bottom shell 10 of the machine body 1 corresponding to the air outlet 33 can be raised relative to the working surface. The hot air blown towards the working surface through the opening 103 can flow in the area enclosed by the second groove 102, thereby improving the drying effect. The area of ​​the second groove 102 at the bottom of the machine body is larger than the area of ​​the drying head 43, thus giving the second groove 102 a larger drying area than the drying head 43. The three sides of the second groove 102 are located near the edge of the machine body, close to the outlet end 32, thereby making full use of the bottom area of ​​the machine body and maximizing the drying area formed by the second groove 102.

[0069] In one embodiment of this disclosure, reference is made to Figure 10 and Figure 12 The machine body 1 has a first groove 101 on the upper side of the partition plate, corresponding to the second groove 102. The first groove 101 is located below the air outlet 33 and communicates with the air outlet 33. That is, a first groove 101 that communicates with the air outlet 33 and is recessed downwards is provided on the bottom side of the machine body 1 facing the drying air duct 3. It can also be understood that the first groove 101 and the second groove 102 are located on opposite sides of the bottom shell 10, and the area of ​​the first groove 101 is larger than the area of ​​the air outlet 33. Without the drying accessory 4 installed, the hot air in the drying air duct 3 is blown out through the air outlet 33 and further diffuses and flows into the first groove 101, so that it can be blown out of the machine body 1 from multiple openings 103. By setting the larger area of ​​the first groove 101, the drying area of ​​the air outlet 33 is increased. In addition, by setting multiple evenly distributed openings 103, the uniformity of drying is improved, and local concentrated heating of the working surface is avoided.

[0070] In one embodiment of this disclosure, reference is made to Figures 4 to 7The inner wall of the drying duct 3 has a ring-shaped stepped surface 35 facing the outlet end 32. The free end of the plug assembly 41 is configured to abut against the stepped surface 35. The stepped surface 35 can limit the insertion depth of the plug assembly 41. When the plug assembly 41 is inserted into place, its free end face abuts against the stepped surface 35, and the user will feel obvious insertion resistance, thus confirming that the insertion is in place. This disclosure improves the user's insertion feel by setting the stepped surface 35, reduces the difficulty of installing the drying accessory 4, and increases the user's insertion success rate.

[0071] In one embodiment of this disclosure, reference continues to be made to... Figures 4 to 7 The top wall of the drying duct 3 is provided with a groove 36 for receiving the baffle 34. The plug assembly 41 is configured to push the baffle 34 to flip up towards the top wall of the drying duct 3 during insertion until it fits into the groove 36. During insertion, the plug assembly 41 can push the baffle 34 to flip up towards the top of the drying duct 3, and the baffle 34 is embedded in the groove 36, thereby avoiding the plug assembly 41, so that the plug assembly 41 can be smoothly inserted into the drying duct 3.

[0072] In one embodiment of this disclosure, reference is made to Figures 4 to 7 The machine body 1 is equipped with an exhaust gas discharge channel 13 and a reversing component. The reversing component can selectively connect the positive pressure pipe 52 to the exhaust gas discharge channel 13, or selectively connect the positive pressure pipe 52 to the drying air duct 3. The exhaust gas discharge channel 13 can be directly connected to the external environment of the machine body 1. Understandably, when the cleaning equipment is performing cleaning operations, the main motor 2 needs to be turned on to create negative pressure in the recovery space 11, at which time airflow will form in the positive pressure pipe 52. However, if the user does not currently require drying, the gas in the positive pressure pipe 52 does not need to flow into the drying air duct 3 for heating, but can be directly discharged from the machine body 1 through the exhaust gas discharge channel 13. In this way, the airflow can be controlled to enter the drying air duct 3 for heating only when drying is required. In usage scenarios where only cleaning is needed and drying is not required, the airflow can be kept out of the drying air duct 3, thereby saving energy consumption required for heating.

[0073] Specifically, the reversing assembly includes a transition channel 14 communicating with the positive pressure duct 52. The transition channel 14 includes a first outlet 141 extending upward and communicating with the exhaust gas discharge channel 13, and a second outlet 142 extending downward and communicating with the drying air duct 3. Airflow from the positive pressure duct 52 can enter the transition channel 14 and flow to the exhaust gas discharge channel 13 through the first outlet 141, or flow to the drying air duct 3 through the second outlet 142.

[0074] The commutation assembly also includes a commutator 15 movably connected within the transition channel 14, specifically, see reference 14. Figure 6 , Figure 7 , Figure 13 and Figure 14 The commutator 15 includes a first blocking portion 151 and a second blocking portion 152, which are configured at an angle. The first blocking portion 151 and the second blocking portion 152 may be integrally formed. For example, in a specific embodiment of this disclosure, the first blocking portion 151 and the second blocking portion 152 may be configured as an arc shape. A rotating cavity 140 adapted to the commutator 15 is provided in the transition channel 14, and the commutator 15 is configured to be rotatably connected in the rotating cavity 140.

[0075] The reversing member 15 can rotate within the rotating cavity 140, thereby causing the first blocking part 151 and the second blocking part 152 to rotate to different angles. Specifically, the reversing member 15 can rotate and switch between a first position and a second position. When rotated to different positions, the first blocking part 151 and the second blocking part 152 can form different passages with the inner wall of the transfer channel 14, thereby enabling the passage of the first outlet 141 or the second outlet 142.

[0076] like Figure 7 As shown, when the reversing member 15 is rotated to the first position, the first blocking part 151 is configured to close the second outlet 142, thereby closing the second outlet 142 and opening the first outlet 141. The airflow from the positive pressure pipe 52 enters the transfer channel 14. Since the second outlet 142 is closed by the first blocking part 151 at this time and the first outlet 141 is in the open state, the airflow can flow out from the first outlet 141, thereby flowing to the exhaust gas discharge channel 13, and then being discharged from the machine body 1.

[0077] like Figure 6 As shown, when the reversing member 15 is rotated to the second position, the second blocking part 152 is configured to block the first outlet 141, thereby closing the first outlet 141 and opening the second outlet 142. The airflow from the positive pressure pipe 52 enters the transfer channel 14. Since the first outlet 141 is closed by the second blocking part 152 at this time and the second outlet 142 is in the open state, the airflow can flow out from the second outlet 142 and flow into the drying air duct 3 for heating, thereby realizing the drying function.

[0078] In one specific embodiment of this disclosure, reference is made to Figure 13 and Figure 14 One end of the reversing member 15 is configured to be drive-connected to a reversing button 16 located outside the body 1. The user can control the reversing member 15 to rotate between a first position and a second position by toggling the reversing button 16. The outer side of the reversing button 16 is exposed outside the body 1 for easy user operation, while its inner side is used for drive-connection with the reversing member 15.

[0079] A drive gear 161, which can be a rack, can be provided on the inner side of the reversing button 16. A driven gear 153, which can be a gear disk arranged along the circumferential direction of the reversing member 15, is provided at the end of the reversing member 15 near the reversing button 16. The driven gear 153 meshes with the drive gear 161. When the reversing button 16 moves in a straight line under the action of an external force, the drive gear 161 drives the driven gear 153 to move, thereby driving the reversing member 15 to rotate between the first position and the second position.

[0080] In one embodiment of this disclosure, such as Figure 13 As shown, the cleaning equipment also includes a detection sensor 7 and a control unit. The detection sensor 7 is configured to be triggered when the reversing member 15 moves to the second position, and the control unit is configured to control the heating element 31 to operate based on the triggered electrical signal. When the detection sensor 7 detects that the reversing member 15 is in the second position, the positive pressure pipe 52 is connected to the drying air duct 3, indicating that the user has a drying need. Therefore, the heating element 31 is controlled to operate, thereby heating the airflow in the drying air duct 3 to generate hot air. Conversely, when the reversing member 15 is not detected to be in the second position, it means that the user does not currently have a drying need, so there is no need to control the heating element 31 to operate. It can be seen that in the usage scenario of cleaning only and not drying, the airflow does not need to enter the drying air duct 3, and the heating element 31 will not operate, thereby saving the energy consumption required for heating.

[0081] In one specific embodiment of this disclosure, such as Figure 13 As shown, the detection sensor 7 can be a microswitch located below the reversing button 16. The reversing button 16 can have two positions: an upper position and a lower position, corresponding to the first and second positions of the reversing member 15, respectively. When the reversing button 16 is in the upper position, the bottom of the reversing button 16 does not contact the detection sensor 7, thus preventing the detection sensor 7 from being triggered. When the reversing button 16 moves to the lower position, the bottom of the reversing button 16 contacts the detection sensor 7, and the detection sensor 7 sends a trigger signal to the control unit. The control unit controls the heating element 31 to operate based on the triggered electrical signal.

[0082] In other embodiments, reference is made to Figure 15 , Figure 16The baffle 34 is pivotally connected to the bottom of the outlet end of the drying duct 3, and the force of the torsion spring ensures that the baffle 34 remains in the closed outlet end 32 state when no external force is involved. When the plug assembly 41 extends from the outlet end 32 and pushes the baffle 34 downward, the baffle is flipped downward by the force of the plug assembly 41 and covers the air outlet 33 of the drying duct, thus closing the air outlet 33 while opening the outlet end 32. Because the bottom of the plug assembly 41 presses down on the baffle after insertion, the baffle remains in the closed outlet 33 state. When the plug assembly is pulled out, the baffle 32 flips upward under the restoring force of the torsion spring, thereby opening the air outlet 33 and closing the outlet end 32. Because the air outlet 33 is blocked by the baffle, the length of the plug assembly 41 extending into the drying duct can be less than the length of the baffle to avoid the plug assembly 41 being too long. Of course, the length of the plug assembly 41 extending into the drying duct can also be greater than the length of the baffle.

[0083] In other embodiments, the air outlet can also be set on the side wall of the drying air duct. The baffle is pivotally connected to the side wall of the outlet end by a torsion spring. The pivoting of the baffle can close the outlet end and open the air outlet for large-area drying, or close the air outlet and open the outlet end for small-area flexible drying.

[0084] This disclosure also provides an air duct switching system applicable to the cleaning equipment described above. The air duct switching system includes: a main motor 2, an exhaust gas discharge channel 13, a drying air duct 3, and a reversing assembly. The drying air duct 3 has an outlet end 32 and an air outlet 33 adjacent to the outlet end 32 and penetrating the wall of the drying air duct 3. A baffle 34 is movably disposed in the drying air duct 3, configured to close or open the outlet end 32. When the baffle 34 is configured to close the outlet end 32, the airflow in the drying air duct 3 is configured to be discharged through the air outlet 33. When the drying accessory 4 pushes the baffle 34 and extends it from the outlet end to open the outlet end 32 of the drying air duct and close the air outlet 33, the airflow in the drying air duct 3 is configured to be discharged through the drying accessory 4. The reversing assembly can selectively open the passage between the main motor 2 and the exhaust gas discharge channel 13, or selectively open the passage between the main motor 2 and the drying air duct 3.

[0085] Application Scenario 1

[0086] In home cleaning scenarios, the cleaning equipment is a fabric cleaning machine, which users use to clean carpet surfaces. Initially, there are no areas requiring drying, so users only use the cleaning function of the fabric cleaning machine and not its drying function.

[0087] The user can move the reversing button 16 to the upper position, thereby keeping the reversing element 15 in the first position, thus closing the second outlet 142 and opening the first outlet 141. At this time, the detection sensor 7 will not be triggered, so the control unit will not control the heating element 31 to work, thereby saving the energy required for heating.

[0088] When the user begins cleaning, the main motor 2 is turned on, creating a negative pressure in the recovery space 11, which causes airflow to be blown out of the positive pressure pipe 52. The airflow from the positive pressure pipe 52 enters the transfer channel 14. Since the second outlet 142 is closed by the first blocking part 151 at this time, and the first outlet 141 is open, the airflow can flow out from the first outlet 141, thereby flowing to the exhaust gas discharge channel 13, and then being discharged from the machine body 1.

[0089] Application Scenario 2

[0090] In home cleaning scenarios, the cleaning equipment is a fabric cleaning machine, which the user uses to clean the carpet surface. At this point, the user has finished cleaning a large area of ​​the carpet and needs to dry this area, while continuing to clean any remaining areas.

[0091] The user needs to move the reversing button 16 to the lower position, so that the bottom of the reversing button 16 contacts the detection sensor 7, and the detection sensor 7 sends a trigger signal to the control unit. At this time, the reversing component 15 moves to the second position, thereby closing the first outlet 141 and opening the second outlet 142, connecting the positive pressure pipe 52 to the drying air duct 3. The control unit can control the heating element 31 to work, thereby heating the airflow in the drying air duct 3 to generate hot air.

[0092] Users do not need to install the drying accessory 4. Instead, they can place the entire fabric cleaning machine on the work surface to be dried and aim the air outlet 33 at the area to be dried. At this time, users can continue to clean other areas. When the main motor 2 is working, it draws in the recovery space 11 to create a negative pressure environment, thereby providing sufficient suction for the suction port of the cleaning brush head 62. At the same time, it supplies air to the drying air duct 3. The hot air generated by the heating element 31 can be blown directly from the air outlet 33 at the bottom of the machine body 1 to the area to be dried, thereby realizing the drying function.

[0093] This disclosure enables the fabric cleaning machine to perform both cleaning and drying functions simultaneously by setting up a main motor 2, without significantly increasing the weight and power consumption of the fabric cleaning machine, thereby improving the user experience.

[0094] Application Scenario 3

[0095] In home cleaning scenarios, the cleaning equipment is a fabric cleaning machine. Users use the fabric cleaning machine to clean localized dirt on the sofa surface. At this point, the user has finished cleaning the dirty area and needs to precisely and quickly dry that area.

[0096] The user needs to move the reversing button 16 to the lower position, so that the bottom of the reversing button 16 contacts the detection sensor 7, and the detection sensor 7 sends a trigger signal to the control unit. At this time, the reversing component 15 moves to the second position, thereby closing the first outlet 141 and opening the second outlet 142, connecting the positive pressure pipe 52 to the drying air duct 3. The control unit can control the heating element 31 to work, thereby heating the airflow in the drying air duct 3 to generate hot air.

[0097] In addition, the user needs to install the drying accessory 4 on the body 1. The plug assembly 41 is configured to push the baffle 34 and extend from the outlet end 32 to block the air outlet 33, so as to connect the drying air duct 3 through the outlet end 32. In the inserted state, the outer wall of the plug assembly 41 can fit tightly against the inner wall of the drying air duct 3 near the outlet end 32, thereby blocking the air outlet 33 provided on the bottom wall of the drying air duct 3. At this time, the hot air in the drying air duct 3 cannot be discharged through the air outlet 33, but will continue to flow into the plug assembly 41 along the extension direction of the drying air duct 3. The plug assembly 41 can have a shape adapted to the outlet end 32, and a sealing structure can be provided at the connection position after plugging, so as to ensure that there is no air leakage gap between the outlet end 32 and the plug assembly 41, and all the hot air in the drying air duct 3 can flow to the drying head 43 through the plug assembly 41.

[0098] Users can manually control the movement of the drying head 43 on the damp sofa surface by holding the drying handle 431. Multiple drying vents 432 are located on the bottom surface of the drying head 43, and these vents are connected to the drying duct 3 via a drying pipe 42 and a plug assembly 41. Hot air from the drying duct 3 can be evenly blown out from the multiple drying vents 432. Users can position the bottom surface of the drying head 43 towards the sofa surface to be dried, allowing the hot air from the drying vents 432 to perform localized, targeted drying.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
