Description

Technical Field

[0001] This application belongs to the field of surface cleaning equipment technology, and specifically relates to a surface cleaning device with a heating component. Background Technology

[0002] In daily life and industrial production, surface cleaning devices such as floor scrubbers and robotic vacuum cleaners have become important tools for maintaining environmental cleanliness. These devices typically use cleaning components on a floor brush to contact the surface to be cleaned, using these components to wipe, scrape, or absorb stains.

[0003] To improve cleaning efficiency, existing technologies, such as patent CN202220029053.6, describe a solution that adds a heating component to a floor brush to enhance its cleaning ability. During the cleaning process, the heating component heats the cleaning surface, increasing the temperature and thus enhancing the dissolving power of the cleaning fluid for oil and stubborn stains, thereby improving the cleaning effect on the surface. Simultaneously, after the cleaning device completes its cleaning operation, the cleaning surface needs to be self-cleaned. After cleaning, the heating component adheres to the surface of the cleaning surface, continuously heating to accelerate the drying process, preventing bacteria growth or odors from prolonged dampness and extending the lifespan of the cleaning surface.

[0004] However, the heating element design needs to accommodate various usage scenarios: when the cleaning component is self-cleaning, or when thick dirt such as mud or oil adheres to its surface and requires separate treatment, the heating element must be separated from the cleaning component to avoid interference with the cleaning process. When the cleaning component is running on uneven ground or has protruding solid particles or other foreign objects on its surface, the heating element needs to have a certain degree of adaptive floating capability to avoid direct collisions with hard objects and ensure the stability of the cleaning process. Therefore, the existing heating element structure, which always remains in contact with the cleaning component, cannot meet the diverse usage needs of users in various scenarios.

[0005] The prior art CN202220029053.6 provides a roller brush cover that can abut or separate from the cleaning component under the action of a driving component. However, a roller brush cover that moves as a whole may lead to unreliable overall installation. If the roller brush cover shifts position during movement, it may fail to block dirt during floor cleaning. Furthermore, the roller brush cover may collide with other objects in the surrounding environment during movement, damaging the roller brush cover. Therefore, while those skilled in the art may require longitudinal movement of the heating component during the structural design of the heating component, it is not advisable to move the heating component by moving the entire roller brush cover.

[0006] To enable the heating element to move independently under the action of the driving component, the transmission component that drives the heating element needs to be located within the extension of the cleaning component, at least partially obscuring it, with pre-reserved displacement space for both the transmission component and the heating element within the extension. However, this structural design still has the following shortcomings: the existing driving structure and the vertical layout of the heating element itself occupy a large amount of space, resulting in a larger overall thickness of the floor brush, making it difficult to flexibly enter low areas such as under furniture and beds, and also affecting the ease of operation when the floor brush turns or rotates; on the other hand, to increase the contact area between the heating element and the cleaning component, the heating element usually adopts a rotating mounting structure concentrically set with the cleaning component. This structure makes it easy for the heating element to undergo longitudinal and lateral displacement relative to the cleaning component when subjected to external forces such as bumps or collisions with foreign objects. When the heating element re-engages with the cleaning component, the lateral displacement may result in a loose fit, affecting the heating efficiency of the heating element and thus adversely affecting the cleaning and drying effect of the cleaning component. Utility Model Content

[0007] This application provides a surface cleaning device with a heating component to solve the technical problems of traditional surface cleaning devices, such as the large space required for the longitudinal movement of the heating component affecting the thinness of the brush, and the excessive lateral movement of the heating component under external force making it difficult to reset.

[0008] The technical solution adopted in this application is as follows:

[0009] A surface cleaning device with a heating component includes a floor brush. The floor brush includes a cleaning component, a heating component, and an extension that at least partially covers the cleaning component. The cleaning component is detachably mounted on the floor brush. The heating component is located on the side of the extension facing the cleaning component. The floor brush also includes a oscillating component and a trigger for driving the oscillating component to rotate. The oscillating component includes a rotating shaft and a mounting portion and a transmission portion located on both sides of the rotating shaft. The oscillating component is mounted on the floor brush via the rotating shaft and rotates around the rotating shaft under the drive of the trigger. The mounting portion is used to mount the heating component and is at least partially located in the extension. The heating component moves longitudinally under the drive of the mounting portion, wherein the lever arm L1 from the mounting portion to the rotating shaft is greater than the lever arm L2 from the transmission portion to the rotating shaft.

[0010] The surface cleaning device with a heating component described in this application also includes the following additional technical features:

[0011] Optionally, the heating assembly includes a heating element. When the trigger is in a first position separated from the transmission part, the heating element abuts against the cleaning element. When the trigger is in a second position abutting against the transmission part, the heating element separates from the cleaning element.

[0012] Optionally, the floor brush includes a first cavity on which the oscillating member is installed and a second cavity that accommodates the trigger member. The first cavity includes an upper shell and a lower shell. The rotating shaft is installed on the upper shell. The lower shell has a through hole. The transmission part extends longitudinally downward from the rotating shaft and at least partially cooperates with the trigger member through the through hole.

[0013] Optionally, the width of the transmission part gradually narrows from the end connected to the rotating shaft along a first direction extending longitudinally.

[0014] Optionally, the mounting portion extends in a direction parallel to the extension portion, and the longitudinal thickness of the mounting portion near the end of the rotating shaft is greater than the longitudinal thickness near the end of the heating assembly.

[0015] Optionally, the floor brush includes a first cavity for accommodating a swinging member, the lower surface of the mounting portion near the lower shell of the first cavity is a horizontal plane, and the upper surface of the mounting portion near the upper shell of the first cavity is an inclined plane; the heating component is attached to the cleaning member, and the lower surface of the mounting portion abuts against the lower shell of the first cavity.

[0016] Optionally, the longitudinal thickness of the mounting portion decreases from the end connected to the rotating shaft along a second direction.

[0017] Optionally, the heating assembly further includes a mounting bracket, the mounting bracket and the mounting part being longitudinally fixedly mounted by a first mounting member, and the first mounting member being laterally mounted to the mounting part by a second mounting member.

[0018] Optionally, the first mounting member and the mounting portion are clearance-fitted in the lateral direction.

[0019] Optionally, the floor brush is further provided with a scraping component disposed on the trigger and a driving component for driving the trigger to rotate, wherein the scraping component and the heating component move synchronously under the drive of the trigger.

[0020] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0021] The surface cleaning device of this application is equipped with a heating component, which can heat the cleaning component as needed during the cleaning process, thereby increasing the temperature of the cleaning component when cleaning the surface and improving the cleaning effect of the cleaning fluid on stubborn stains such as oil. After cleaning, during the self-cleaning process of the cleaning component, the heating component can separate from the cleaning component to provide a self-cleaning space, and then adhere to the outer surface of the cleaning component after the cleaning process to heat the component, facilitating rapid drying. Alternatively, during the self-cleaning process, the heating component can switch between separation and contact with the cleaning component to utilize the rotation of the cleaning component to clean dirt trapped between the cleaning component and the heating component, as well as dirt adhering to the surface of the heating component. Furthermore, to allow the heating component to movably engage with the cleaning component, the heating component is mounted on the floor brush via a swinging component. The swinging component engages with a trigger that drives the swinging component to rotate, and has a mounting part for mounting the heating component and a transmission part that can rotate around a pivot under the action of the trigger. The trigger and transmission unit cooperate to cause the oscillating component to rotate. The heating element mounted on the mounting part rotates synchronously around the axis under the drive of the oscillating component, thereby driving the heating assembly to move longitudinally. To reduce the influence of the external environment on the movement of the oscillating component, the oscillating component is located inside the floor brush. The floor brush includes an extension that at least partially covers the cleaning component, and an extension for mounting the heating assembly is at least partially located within the extension and moves longitudinally within the extension.

[0022] The trigger for driving the rotation of the heating element is typically located inside the brush body behind the cleaning element. The heating element, which selectively contacts the cleaning element, needs to be positioned above it, necessitating a oscillating element to transmit longitudinal displacement. To ensure the heating element can contact and separate from the cleaning element, meeting the heating requirements during floor cleaning while maintaining sufficient clearance for cleaning, the heating element needs ample longitudinal displacement. However, since the brush needs to reach under sofas, beds, and other low-lying areas, its thickness must be as thin as possible. Therefore, the oscillating element is pivotally mounted on the brush via a pivot, forming a lever to reduce the brush's thickness. Specifically, by setting the mounting arm L1 of the swing component to be greater than the transmission arm L2, the driving method of the heating component is optimized by using the lever principle. This design allows the trigger component to drive the transmission component to make a small movement, which in turn drives the heating component to complete sufficient vertical movement through the mounting component. There is no need to reserve too much vertical space for the drive structure, thereby effectively reducing the overall thickness of the floor brush. This allows the cleaning device to easily enter low areas that were previously difficult to reach, such as the bottom of wardrobes and under sofas, greatly expanding the cleaning range.

[0023] Furthermore, since the lever arm L1 is greater than the lever arm L2, according to the lever principle, the longer the lever arm, the greater the torque generated under the same force, and the more significant the corresponding end displacement. Specifically, when the trigger drives the transmission part to rotate around the shaft by a small angle, the displacement at the end of the transmission part is small because the lever arm L2 is shorter; however, under the lever action, the displacement at the end of the mounting part connected to the other end of the shaft is greater than that of the transmission part because the lever arm L1 is longer. This means that by simply rotating the swinging part by a small angle, the heating component located at the end of the mounting part can achieve a sufficiently large longitudinal displacement to meet the requirements of contacting or separating from the cleaning component. This design brings many conveniences to the actual use of the surface cleaning device. For example, when cleaning a surface with dirt, oil, or other contaminants, it is necessary to separate the heating component from the cleaning component. At this time, the trigger only needs to drive the transmission part to make a slight rotation, and the mounting part can drive the heating component to quickly move to the appropriate position separated from the cleaning component. The entire process requires minimal movement of the transmission unit, significantly reducing the vertical space needed for the drive structure within the floor brush. This effectively lowers the overall thickness of the brush and creates more space for the design and installation of other components. This allows the cleaning device to easily access previously inaccessible low-lying areas, such as under wardrobes and sofas, greatly expanding its cleaning range.

[0024] Building upon this, since the heating component's significant displacement can be achieved with only a small angle rotation of the oscillating component, on one hand, it makes position control of the trigger component during rotation more convenient and precise. Compared to large-scale movement of the trigger component and / or transmission unit, changing the position of the mounting part by small-scale rotation of the transmission unit results in more accurate positioning of the transmission unit, allowing the heating component to accurately contact or separate from the cleaning component as needed. On the other hand, the small-scale rotation of the trigger component and transmission unit also allows for faster position adjustments based on usage. For example, during cleaning, if the floor brush encounters uneven ground and vibrates, even if the heating component floats, it can quickly return to its original position with minor adjustments from the oscillating component, re-engaging in close contact with the cleaning component. This significantly reduces the problem of loose contact caused by excessive displacement and difficulty in returning to position of the heating component, thus ensuring uniform heating of the cleaning component and enabling the cleaning fluid to continuously and efficiently dissolve oil and other stains. During the self-cleaning phase, it also ensures that the heating component maintains good contact with the cleaning component, accelerating the drying speed of the cleaning component and improving the overall cleaning effect and user experience. Alternatively, if the heating element and the cleaning element become stuck due to dirt during operation, the position between them can be quickly adjusted by slightly rotating the transmission part driven by the trigger element. This shortens the triggering time of the trigger element, allowing the position of the heating element to be adjusted more quickly.

[0025] Furthermore, when the longitudinal displacement of the heating element is constant, the mounting part with a larger lever arm only needs to rotate a small angle around the axis to cause the heating element to undergo the preset longitudinal displacement. The rotating mounting part brings both longitudinal and lateral displacement to the heating element. With the same longitudinal displacement, a longer rotation radius and a smaller rotation angle result in a smaller lateral displacement. Therefore, during the movement of the heating element driven by the mounting part with a longer lever arm L1, the lateral displacement of the heating element is smaller, allowing it to move from a position separate from the cleaning component to a contact position, and / or, the lateral displacement from a contact position to a separation position is even smaller. When the heating element and the cleaning component are in the contact position, there is a larger contact area, ensuring the heating effect on the cleaning component and thus guaranteeing the stability of the cleaning and drying effects.

[0060] Example 1:

[0061] This embodiment provides a surface cleaning device with a heating component 3. Specifically, the surface cleaning device in this embodiment is used to wipe the surface to be cleaned and has a cleaning component for wiping the surface. To improve the cleaning efficiency of the cleaning component, a heating component located above the cleaning component is also provided on the floor brush to heat the cleaning component and thus better dissolve dirt. The surface cleaning device in this embodiment can be a handheld surface cleaning device with a body and a handle, or it can be a surface cleaning device of any form, such as a self-moving cleaning robot.

[0062] like Figures 1 to 3As shown, the brush includes a floor brush 1, which includes a cleaning component 2, a heating component 3, and an extension 4 that at least partially covers the cleaning component 2. The cleaning component 2 is detachably mounted on the floor brush 1. The heating component 3 is located on the side of the extension 4 facing the cleaning component 2. The floor brush 1 also includes a swing component 5 and a trigger 6 for driving the swing component 5 to rotate. The swing component 5 includes a rotating shaft 51 and a mounting portion 52 and a transmission portion 53 located on both sides of the rotating shaft 51, respectively. The swing component 5 is mounted on the floor brush 1 via the rotating shaft 51 and rotates around the rotating shaft 51 under the drive of the trigger 6. The mounting portion 52 is used to mount the heating component 3 and is at least partially located on the extension 4. The heating component 3 moves longitudinally under the drive of the mounting portion 52. The lever arm L1 from the mounting portion 52 to the rotating shaft 51 is greater than the lever arm L2 from the transmission portion 53 to the rotating shaft 51.

[0063] Specifically, the extension 4 is constructed as part of the housing of the floor brush 1, located above the cleaning component 2, and the projection of the extension 4 in the vertical direction coincides with a portion of the cleaning component 2, i.e. Figure 2 The portion to the left of the longitudinal section line A is the extension 4. The existence of the extension 4 provides room for the movement of the swing member 5 within the floor brush 1, reducing the influence of the external environment on the movement of the swing member 5. Figure 3 The diagram in F1 shows the direction of force applied when the mounting part 52 drives the heating component 3 to move. Figure 3 F2 shows the direction in which the trigger 6 applies force to the transmission part 53.

[0064] It should be noted that the heating component 3 located above the cleaning component 2 needs to heat the cleaning component 2 as needed during the surface cleaning operation, thereby increasing the temperature of the cleaning component 2 when cleaning the surface, thus improving the cleaning effect of the cleaning liquid on stubborn stains such as oil. Furthermore, after the cleaning operation is completed, during the self-cleaning process of the cleaning component 2, the heating component 3 needs to be able to separate from the cleaning component 2 to provide a self-cleaning space, and after the cleaning process is completed, it needs to adhere to the outer surface of the cleaning component 2 to heat it, facilitating rapid drying of the cleaning component 2. Therefore, the heating component 3 is mounted on the oscillating component 5 mounting part 52, which allows for longitudinal movement, so that the heating component 3 can be movably mounted on the floor brush 1.

[0065] The trigger 6, used to drive the rotation of the heating element 3, is typically located inside the main body of the floor brush 1 behind the cleaning element 2. The heating element 3, which selectively contacts the cleaning element 2, needs to be positioned above it. Therefore, a swing element 5 is required to transmit longitudinal displacement. To ensure that the heating element 3 can contact and separate from the cleaning element 2, meet the heating requirements of the cleaning element 2 during floor cleaning, and maintain sufficient clearance between the heating element 3 and the cleaning element 2 for cleaning dirt, the heating element 3 needs sufficient longitudinal displacement. However, since the floor brush 1 needs to reach into low areas such as under sofas and beds for cleaning, its thickness must be as thin as possible. Therefore, the swing element 5 is pivotally mounted on the floor brush 1 via a pivot, forming a lever to reduce the thickness of the floor brush 1.

[0066] Specifically, the floor brush 1 is also provided with a swinging part 5 and a triggering part 6. The mounting part 52 of the swinging part 5 is used to install the heating component 3. The transmission part 53 can rotate around the rotating shaft 51 under the action of the triggering part 6, and at the same time, the mounting part 52 rotates around the rotating shaft 51 synchronously to drive the heating component 3 to move longitudinally.

[0067] During this process, since the lever arm L1 of the mounting part 52 of the swinging part 5 is set to be greater than the lever arm L2 of the transmission part 53, the driving method of the heating component 3 is optimized by means of the lever principle. This design allows the triggering part 6 to drive the transmission part 53 to make a small movement, which can drive the heating component 3 to complete a sufficient longitudinal movement through the mounting part 52. There is no need to reserve too much vertical space for the driving structure, thereby effectively reducing the overall thickness of the floor brush 1. This allows the cleaning device to easily enter low areas that were previously difficult to reach, such as the bottom of the wardrobe and under the sofa, greatly expanding the cleaning range and leaving space for the installation of other components inside the floor brush 1.

[0068] Furthermore, since the lever arm L1 is greater than the lever arm L2, according to the lever principle, the longer the lever arm, the greater the torque generated under the same force, and the more significant the corresponding end displacement. Specifically, when the trigger 6 drives the transmission part 53 to rotate around the rotating shaft 51 by a small angle, the displacement at the end of the transmission part 53 is small because the lever arm L2 is shorter; however, under the lever action, the displacement at the end of the mounting part 52 connected to the other end of the rotating shaft 51 is greater than that of the transmission part 53 because the lever arm L1 is longer. This means that by simply rotating the swinging member 5 by a small angle, the heating component 3 located at the end of the mounting part 52 can achieve a sufficiently large longitudinal displacement to meet the requirements of contacting or separating from the cleaning component 2. This arrangement brings many conveniences in the actual use of the surface cleaning device. For example, when cleaning a surface to be cleaned that is covered with dirt, oil, or other contaminants, it is necessary to separate the heating component 3 from the cleaning component 2. At this time, the trigger 6 only needs to drive the transmission part 53 to make a slight rotation, and the mounting part 52 can drive the heating component 3 to quickly move to a suitable position separated from the cleaning component 2. The entire process eliminates the need for a large movement space in the transmission unit 53, thus significantly reducing the vertical space reserved inside the floor brush 1 for the drive structure. This effectively reduces the overall thickness of the floor brush 1, freeing up space for the design and installation of other components within the floor brush 1. This allows the cleaning device to easily access previously inaccessible low-lying areas, such as the bottom of wardrobes and under sofas, greatly expanding the cleaning range.

[0069] Based on this, since the large displacement of the heating component 3 can be achieved by only rotating the swinging member 5 by a small angle, on the one hand, it makes the position control of the triggering member 6 during rotation more convenient and precise. Compared to making the triggering member 6 and / or the transmission part 53 move significantly, and changing the position of the mounting part 52 by rotating the transmission part 53 slightly, the positioning of the transmission part 53 is more accurate, allowing the heating component 3 to accurately contact or separate from the cleaning part 2 as needed. On the other hand, the small-amplitude rotation of the triggering member 6 and the transmission part 53 can also be adjusted more quickly according to the usage. For example, during the cleaning process, when the ground brush 1 encounters an uneven surface and bumps, even if the heating component 3 floats, it can quickly return to its original position with the slight adjustment of the swinging member 5 and re-fit tightly with the cleaning part 2. This greatly reduces the problem of loose contact with the cleaning part 2 caused by excessive displacement and difficulty in returning to its original position of the heating component 3, thereby ensuring the uniform heating of the cleaning part 2 by the heating component 3, and enabling the cleaning fluid to continuously and efficiently dissolve stains such as oil. During the self-cleaning phase, it ensures that the heating element 3 and the cleaning element 2 maintain good contact at all times, accelerating the drying speed of the cleaning element 2 and improving the overall cleaning effect and user experience. Alternatively, if the heating element 3 and the cleaning element 2 become stuck due to dirt during operation, the position between the heating element 3 and the cleaning element 2 can be quickly adjusted by slightly rotating the transmission part 53 driven by the trigger 6, shortening the triggering time of the trigger 6 and thus allowing the position of the heating element 3 to be adjusted more quickly.

[0070] Furthermore, when the longitudinal displacement of the heating component 3 is constant, the mounting part 52 with a larger lever arm only needs to rotate a small angle around the axis to cause the heating component 3 to undergo the preset longitudinal displacement. The rotating mounting part 52 brings both longitudinal and lateral displacement to the heating component 3. With the same longitudinal displacement, a longer rotation radius and a smaller rotation angle result in a smaller lateral displacement. Therefore, during the movement of the heating component 3 driven by the mounting part 52 with a longer lever arm L1, the lateral displacement of the heating component 3 is small. This makes the lateral displacement of the heating component 3 from the separation position to the contact position with the cleaning component 2, and from the contact position to the separation position even smaller. When the heating component 3 and the cleaning component 2 are in the contact position, they have a larger contact area, ensuring the heating effect on the cleaning component 2 and thus guaranteeing the stability of the cleaning and drying effects.

[0071] Preferably, the mounting part 52 and the transmission part 53 are integrally formed and a first rotating hole is provided at the connection between the two. The floor brush 1 housing is provided with a downwardly extending rotating seat. The rotating seat is provided with a second rotating hole that is aligned with the first rotating hole. The rotating shaft 51 is inserted into the first rotating hole and the second rotating hole in sequence, thereby realizing the rotational connection between the swinging member 5 and the rotating seat.

[0072] Preferably, as another implementation of this embodiment, the swing member 5 is provided with a rotating shaft 51 protruding from the surface of the swing member 5, and the mounting part 52 and the transmission part 53 are respectively located on both sides of the rotating shaft 51. The floor brush 1 is provided with a first rotating hole and a second rotating hole, and the two ends of the rotating shaft 51 are respectively engaged with the first rotating hole and the second rotating hole, so that the swing member 5 is rotatably mounted on the floor brush 1.

[0073] Preferably, as another implementation of this embodiment, the swing member 5 is provided with a through hole, and the floor brush 1 is provided with a first mounting post and a second mounting post for mounting the swing member 5. The first mounting post and the second mounting post are respectively inserted into the through hole of the swing member 5 from both sides to mount the swing member 5 on the floor brush 1.

[0074] Preferably, as another implementation of this embodiment, the swing member 5 is provided with mounting grooves, two of which are respectively provided on both sides of the swing member 5. The floor brush 1 is provided with a first mounting post and a second mounting post that cooperate with the mounting grooves. The first mounting post and the second mounting post cooperate with the mounting grooves on both sides of the swing member 5 to mount the swing member 5 on the floor brush 1, and enable the swing member 5 to rotate around the first mounting post and the second mounting post. The swing member 5 can also be pivotally mounted on the floor brush 1 in any mounting method that can be conceived by those skilled in the art, with one side of the swing member 5 being a mounting part 52 for mounting the heating component 3, and the other side being a transmission part 53 that cooperates with the trigger member.

[0075] Optionally, there may be one swing member 5 for mounting the heating assembly 3, and the swing member 5 is positioned corresponding to the middle of the heating assembly 3 to ensure stable mounting; or there may be two, three, four, five or six swing members 5. Further, in order to ensure that the heating assembly 3 is subjected to uniform force in the axial direction, taking the example of having two swing members 5, the two swing members 5 may be symmetrically arranged about the axis of the heating assembly 3.

[0076] As a preferred embodiment of this example, Figure 2 , Figure 4 As shown, the heating assembly 3 includes a heating element 31, a trigger element 6 in a first position separated from the transmission part 53, the heating element 31 abutting against the cleaning element 2, and the trigger element 6 in a second position abutting against the transmission part 53, the heating element 31 being separated from the cleaning element 2.

[0077] Figure 2 The trigger is in the first position. Figure 4When the trigger 6 is in the second position and the trigger 6 is in the first position separated from the transmission part 53, the heating element 31 can naturally keep in contact with the cleaning element 2 under the action of gravity. In this state, during the cleaning work, the heating element 31 can continuously heat the cleaning element 2 to ensure that the cleaning fluid always maintains a high activity to dissolve the oil stains. During the self-cleaning process, the heating element 31 can also work closely with the heating element 2 to achieve hot water self-cleaning and improve the efficiency of self-cleaning. After the self-cleaning is completed, the close contact between the heating element 31 and the cleaning element 2 can also quickly increase the temperature of the cleaning element 2 and accelerate the evaporation of water.

[0078] When the heating element 31 comes into contact with the cleaning element 2, the swing element 5 is not affected by the trigger element 6 and naturally comes into contact with the cleaning element 2 under the action of gravity. When large particles of dirt or hard dirt appear between the heating element 31 and the cleaning element 2, the heating element 31 has a certain amount of upward clearance space, which reduces the possibility of the cleaning element 2 getting stuck.

[0079] When the trigger 6 switches to the second position abutting against the transmission part 53, the heating element 31 moves with the mounting part 52 and separates from the cleaning element 2. In actual operation, for example, when a large amount of dried dirt or sticky oil adheres to the surface of the cleaning element 2, the separation of the heating element 31 provides sufficient cleaning space for the cleaning element 2, preventing dirt from accumulating between the heating element 31 and the cleaning element 2. Simultaneously, during the self-cleaning rinsing phase of the cleaning element 2, the separation of the heating element 31 prevents it from obstructing the flow of cleaning fluid, ensuring that every area of ​​the cleaning element 2 is thoroughly rinsed, thus improving the thoroughness of self-cleaning. This switching mechanism of the heating component 3 abutting against and separating from the cleaning element 2 allows the working state of the heating component 3 to match the cleaning requirements, ensuring both the heating efficiency and preventing the heating component 3 from interfering with the self-cleaning process or the cleaning of the cavity of the cleaning element 2.

[0080] Furthermore, when the trigger 6 is separated from the transmission part 53, the heating element 31 abuts against the cleaning element 2. This ensures that the force exerted on the heating element 31 by the rotation of the cleaning element 2 or the turning or collision of the floor brush 1 will not be transmitted from the oscillating member 5 to the trigger 6. In other words, when the heating element 31 heats the cleaning element 2, the trigger 6 will not be affected by the adverse forces exerted by the cleaning element 2. When the trigger 6 contacts the oscillating member 5, the heating element 31 separates from the cleaning element 2. The fact that the heating element 31 is not in contact with the cleaning element 2 ensures that the force transmission path between the cleaning element 2 and the trigger 6 is cut off in all working states, reducing the obstruction effect of the heating element 31 on the rotation of the cleaning element 2.

[0081] In one implementation of this embodiment, the heating element 31 includes a heating element body and a heat conductor disposed between the heating element body and the cleaning element 2. Preferably, the heating element 31 is a PTC heater, with a heat conductor sleeved on the outside. The heat conductor is a flat aluminum tube, and the PTC heater is located inside the flat aluminum tube. The heating element 31 extends along the width direction of the cleaning element 2, and its extension length is consistent with the width of the cleaning element 2. Optionally, the heating element 31 can also be any heating element known to those skilled in the art, such as a magnetic heating element or an infrared heating element.

[0082] As another preferred embodiment of this example, Figure 2 , Figure 4 As shown, the floor brush 1 includes a first cavity 11 on which the swing member 5 is installed and a second cavity 12 that accommodates the trigger member 6. The first cavity 11 includes an upper shell 13 and a lower shell 14. The rotating shaft 51 is installed on the upper shell 13. The lower shell 14 has a through hole 141. The transmission part 53 extends longitudinally downward from the rotating shaft 51 and at least partially passes through the through hole 141 to cooperate with the trigger member 6.

[0083] The partitioned design of the first cavity 11 and the second cavity 12 provides an orderly installation space for the swing component 5 and the trigger component 6. The upper shell 13 and lower shell 14 of the first cavity 11 cooperate to achieve stable installation of the swing component 5, while the second cavity 12 provides an independent movement space for the trigger component 6. Specifically, the rotating shaft 51 is installed on the upper shell 13, ensuring the axis of the swing component 5 is fixed during rotation and reducing the possibility of shaking of the heating component 3 due to loosening of the rotating shaft 51. The through hole 141 in the lower shell 14 provides a precise movement channel for the transmission part 53, allowing it to pass through the through hole 141 and stably cooperate with the trigger component 6 in the second cavity 12. During cleaning, when the floor brush 1 tilts during a turn, the fixing effect of the upper shell 13 on the rotating shaft 51 ensures that the swing component 5 will not change its movement trajectory due to gravity. The cooperation between the transmission part 53 and the trigger component 6 through the through hole 141 is also unaffected by the tilt of the floor brush 1, maintaining a stable transmission of driving force.

[0084] Specifically, such as Figure 2 , Figure 4 As shown, the first cavity 11 includes a mounting cavity 111 located on the front side and a receiving cavity located on the rear side. The projection of the upper shell 13 along the vertical direction covers the mounting cavity 111 and the receiving cavity. The mounting cavity 111 is used to mount the heating assembly 3 and has a downward opening. The lower shell 14 forms the bottom wall of the receiving cavity. The front end of the mounting part 52 is located in the mounting cavity 111 and connected to the heating assembly 3. The rear end of the mounting part 52 is located in the receiving cavity. One end of the transmission part 53 is located in the receiving cavity and connected to the mounting part 52, and the other end extends downward through the through hole 141 of the lower shell 14 into the second cavity 12.

[0085] As a preferred example of this implementation, such as Figures 2 to 4 As shown, the width of the transmission part 53 gradually narrows from the end connected to the rotating shaft 51 along its longitudinal direction in a first direction.

[0086] Figure 3 The arrow X points to the first direction. The transmission part 53 is designed such that it has a larger width at the end connected to the mounting part 52, ensuring the stability of the connection with the mounting part 52, while its other end gradually narrows along the first direction, so that the transmission part 53 has a smaller width at the end away from the rotating shaft 51. In this way, when the trigger 6 needs to drive the transmission part 53 and move the heating component 3, the narrow end makes contact first, which can effectively disperse the impact force at the moment of contact. In cleaning scenarios, such as when the user needs to quickly separate the heating component 3 to clean up sudden mud and dirt, the trigger 6 pushes the transmission part 53, and the narrow end is subjected to force first, which can reduce abnormal noise and wear caused by hard impact, and allow the heating component 3 to more smoothly separate and adhere to the cleaning component 2.

[0087] Meanwhile, the gradual width of the transmission part 53, while ensuring the stability of the connection with the mounting part 52, reduces the requirement of the transmission part 53 for the internal installation space of the floor brush 1, and also reduces the probability of the transmission part 53 interfering with the internal components of the floor brush 1 during the movement of the floor brush 1.

[0088] As a preferred embodiment of this example, Figure 2 , Figure 4 As shown, the mounting portion 52 extends in a direction parallel to the extension portion 4, and the longitudinal thickness of the mounting portion 52 near the rotating shaft 51 is greater than the longitudinal thickness near the heating component 3.

[0089] The end of the mounting part 52 near the rotating shaft 51 needs to withstand the centrifugal force that drives the heating component 3 to rotate and ensure reliable installation of the rotating shaft 51 and the floor brush 1. The relatively large longitudinal thickness ensures sufficient structural strength in this part, preventing bending or breakage during long-term use and providing reliable support for the stable movement of the heating component 3. The thinner thickness at the end near the heating component 3 reduces the overall weight of the mounting part 52, resulting in less inertia for the swinging component 5 during rotation. The triggering component 6 requires only a small driving force to drive the heating component 3 to move quickly. For example, when the floor brush 1 encounters protruding solid particles during cleaning, the thinner end of the mounting part 52 responds quickly and floats upwards in conjunction with the heating component 3 after the impact. Once the particles are passed, the mounting part 52 quickly returns to its original position and adheres to the cleaning component 2. Furthermore, the thinner design at the end near the heating component 3 allows for greater longitudinal movement of the mounting part 52 within the first cavity, enabling a larger gap between the heating component 3 and the cleaning component 2 when moving away from it, facilitating better operation of the cleaning component 2.

[0090] As a preferred example of this implementation, such as Figure 2 As shown, the floor brush 1 includes a first cavity 11 that accommodates the swinging member 5. The mounting part 52 is horizontal near the lower surface of the lower shell 14 of the first cavity 11, and inclined near the upper surface of the upper shell 13 of the first cavity 11. The heating component 3 is attached to the cleaning member 2, and the lower surface of the mounting part 52 abuts against the lower shell 14 of the first cavity 11.

[0091] The mounting part 52 has a larger contact area with the lower shell 14 of the first cavity 11 due to its horizontal lower surface, providing stable support for the mounting part 52. When the heating component 3 is in contact with the cleaning component 2 to heat the cleaning component 2, it may be subjected to force due to the rotational friction of the cleaning component 2 or the bumps of the floor brush 1, and this force is transmitted to the mounting part 52. At this time, the lower surface of the mounting part 52 abuts against the lower shell 14 of the first cavity 11, so that the lower shell 14 can provide a more stable support for the mounting part 52, offsetting most of the force transmitted from the cleaning component 2 by the heating component 3. On the one hand, it improves the contact stability between the heating component 3 and the cleaning component 2, and improves the working stability of the heating component 3; on the other hand, it reduces the adverse effects of external forces on the mounting part 52, improves the stability of the mounting part 52 during the heating process of the heating component 3, and helps to extend the service life of the mounting part 52. Furthermore, when the trigger 6 is in the first position, the bottom surface of the mounting portion 52 is in contact with the surface of the extension portion 4. The extension portion 4 serves to limit the mounting portion 52, ensuring that the heating element 31 and the cleaning element 2 have a suitable contact position and contact depth. This reduces the probability of local gaps appearing when the heating element 3 and the cleaning element 2 are in contact due to the tilt of the mounting portion 52, thus ensuring the uniformity of heating.

[0092] Secondly, the inclined surface design of the upper part effectively reduces the space occupied between the mounting part 52 and the upper shell 13 of the first cavity 11. Without affecting the rotation of the swinging member 5, it reduces the overall height of the first cavity 11, indirectly reducing the thickness of the floor brush 1. For example, in the compact design of the floor brush 1, the inclined upper surface of the mounting part 52 can avoid interference with the upper shell 13, so that the swinging member 5 will not collide with the upper shell 13 even when it rotates to the maximum angle. This ensures the range of motion of the heating component 3 and allows the floor brush 1 to be made thinner. In addition, when the floor brush 1 moves on the uneven surface to be cleaned, the contact between the horizontal lower surface and the lower shell 14 of the first cavity 11 can provide a stable reference position for the heating component 3, reducing the displacement of the heating component 3 caused by the bumps of the floor brush 1, ensuring that it always maintains good heating contact with the cleaning component 2, and improving the stability of the cleaning and drying effect.

[0093] Preferably, such as Figure 2 , Figure 4As shown, when the heating component 3 is attached to the cleaning component 2, the upper surface of the mounting part 52 gradually extends downward from the side near the rotating shaft 51 to the side near the heating component 3; and there is a swing gap 130 between the upper surface of the first cavity 11 and the upper surface of the mounting part 52. When the swinging component 5 swings at the same angle, the side of the mounting part 52 near the rotating shaft 51 rotates less, so the swing gap 130 between it and the upper surface of the first cavity 11 is smaller, and the side of the mounting part 52 near the heating component 3 rotates more, so the swing gap 130 between it and the upper surface of the first cavity 11 is larger.

[0094] As a preferred embodiment of this example, Figures 2 to 4 As shown, the longitudinal thickness of the mounting portion 52 decreases from the end connected to the rotating shaft 51 along the second direction.

[0095] Figure 3 The middle arrow Y points to the second direction. From a structural perspective, the thicker thickness of the mounting part 52 near the rotating shaft 51 can withstand the larger torque generated by the heating component 3, ensuring the structural stability of the mounting part 52 during long-term rotational motion, thus providing basic support for the stable movement of the heating component 3. The gradually decreasing thickness along the second direction significantly reduces the weight of the mounting part 52 away from the rotating shaft 51, making the center of gravity of the swinging component 5 closer to the rotating shaft 51, and greatly reducing the inertial resistance during rotation. In practical use, this means that when the trigger 6 drives the transmission part 53, the mounting part 52 can more nimbly drive the heating component 3 to move. For example, when the user needs to quickly separate the heating component 3 to clean sudden dirt, the heating component 3 can complete the displacement in a short time, improving the convenience of operation. At the same time, the lightweight end design also reduces the floating amplitude of the heating component 3 when bumpy. Even if the floor brush 1 encounters large undulations, the heating component 3 can quickly return to its position and adhere to the cleaning component 2, avoiding heating interruption due to excessive shaking and ensuring that the cleaning fluid continues to work efficiently.

[0096] As a preferred embodiment of this example, Figure 5 As shown, the floor brush 1 is also provided with a scraping component 9 on the trigger component 6 and a driving component 10 that drives the trigger component 6 to rotate. The scraping component 9 and the heating component 3 move synchronously under the drive of the trigger component 6.

[0097] The scraper 9 and heating assembly 3 move synchronously under the drive of the trigger 6, achieving coordinated operation of cleaning and heating functions. When the trigger 6 is in the second position, it contacts the transmission part 53 and drives the swinging part 5 to rotate, thereby separating the heating assembly 3 from the cleaning part 2. At this time, the scraper 9 also separates from the cleaning part 2 under the drive of the trigger 6. When the trigger 6 is in the first position, it releases the transmission part 53, and the mounting part 52 drives the heating assembly 3 to contact the cleaning part 2. The scraper 9 also contacts the cleaning part 2 under the push of the trigger 6. The scraper 9, which can flexibly contact or separate from the cleaning part 2, can adapt to different working states of the surface cleaning equipment. For example, when it is necessary to scrape off dirt from the outer surface of the cleaning component 2, the scraper 9 and the heating component 3 simultaneously come into contact with the cleaning component 2. The scraper 9 scrapes off the dirt from the surface of the cleaning component 2, and the heating component 3 heats the cleaning component 2 to accelerate the dissolution of the dirt. When it is necessary to dry the surface of the cleaning component 2, the heating component 3 and the scraper 9 simultaneously come into contact with the cleaning component 2. The scraper 9 scrapes off the cleaning liquid on the cleaning component 2, and the heating component 3 irons and dries the cleaning component 2 after the water has been scraped off, thus accelerating the drying process of the cleaning component 2.

[0098] On the other hand, when the cavity of the cleaning component 2 needs to be cleaned or is dirty, the scraper 9 and the heating component 3 can be separated from the cleaning component 2 at the same time to release the dirt that may be trapped between the cleaning component 2 and the scraper 9 and / or the cleaning component 2 and the heating component 3, while providing flushing space for the dirt to be flushed away by the cleaning fluid.

[0099] This embodiment does not limit the structure of the scraping member 9. It can be any structure that can come into contact with the cleaning member 2 to scrape away dirt, such as comb teeth, scraper strips, or a component composed of comb teeth and scraper strips.

[0100] Preferably, the drive component 10 is disposed inside the floor brush body on the rear side of the floor brush 1, such as... Figure 5 As shown, the trigger 6 is provided with a mating gear 61, and the output end of the drive 10 is constructed as a transmission gear 101. The drive 10 drives the transmission gear 101 to rotate, and through the meshing transmission of the transmission gear 101 and the mating gear 61, it drives the trigger 6 to rotate. The rotation of the trigger 6 drives the scraping part 9 to rotate synchronously, thereby realizing the synchronous movement of the scraping part 9 and the swinging part 5.

[0101] Specifically, the trigger 6 has an arc-shaped structure, the gear 61 is located on the outer convex side of the arc-shaped structure, and the scraper 9 is installed on the inner concave side of the arc-shaped structure.

[0102] This embodiment does not limit the synchronization of movement between the scraping component 9 and the swinging component 5. It is understood that when the triggering component 6 is between the first and second positions, the scraping component 9 has already separated from the cleaning component 2, but the scraping component 9 has not moved to the maximum distance between itself and the cleaning component 2. Therefore, in another embodiment, it can be configured such that when the triggering component 6 just switches from the first position to the second position, the triggering component 6 is not in contact with the transmission part 53, and the heating component 3 is still in contact with the cleaning component 2. When the triggering component 6 moves to a position between the first and second positions, the triggering component 6 abuts against the transmission part 53 and drives the heating component 3 to move longitudinally, at which point the heating component 3 separates from the cleaning component 2. That is, during the switching process of the triggering component 6 from the first position to the second position, the scraping component 9 separates from the cleaning component 2 first, and the heating component 3 separates from the cleaning component 2 later than the scraping component 9.

[0103] As one implementation of this embodiment, the surface cleaning device can be a handheld surface cleaning device. Specifically, the surface cleaning device in this embodiment also includes a body 120 pivotally connected to the floor brush 1 and a dispensing component 110 for wetting the cleaning component 2. The body 120 can rotate relative to the floor brush 1 to accommodate different working postures of the operator. A handle is provided at the top of the body 120. When cleaning the floor, the angle between the body 120 and the floor brush 1 is close to 90° to facilitate user support. When the surface to be cleaned is below an obstacle such as a table, the user can hold the handle to rotate the body 120 towards the rear of the floor brush 1, reducing the vertical height of the body 120 so that the cleaning component 2 can enter the bottom of the table. The dispensing component 110 has multiple dispensing ports along the extension direction of the cleaning component 2. Cleaning liquid flows out from these ports to evenly wet the cleaning component 2 or the surface to be cleaned. The cleaning liquid can be clean water, clean water mixed with detergent, etc. The floor brush 1 has a suction port 15 on the rear side of the corresponding cleaning component 2. The floor brush 1 also has a suction hose inside, one end of which is connected to the suction port 15, and the other end of which passes rearward through the hinge between the floor brush 1 and the body 120, extending upward into the body 120 and connecting to the suction pipe inside the waste collection tank. The waste collection tank is detachably connected to the body 120 and is used to temporarily store the waste liquid collected during cleaning. The top of the floor brush 1 has a detachable water tank 180, which provides cleaning fluid to the dispensing component 110.

[0104] In this embodiment, the cleaning component 2 is as follows: Figure 2 The tracked cleaning component shown includes a front roller, a rear roller, and a cleaning cloth sleeved on the front and rear rollers. The outer surface of the cleaning cloth has tufts of hair. Alternatively, the cleaning component 2 can also be any type of wiping component capable of cleaning the floor, such as a single roller structure, a double roller structure, or a conical roller structure.

[0105] Example 2:

[0106] In this embodiment, as Figure 6 , Figure 7 As shown, the heating assembly 3 also includes a mounting bracket. The mounting bracket and the mounting part 52 are longitudinally fixedly installed by a first mounting member 7, and the first mounting member 7 is laterally installed with the mounting part 52 by a second mounting member 8.

[0107] The dual mounting method, employing a first mounting component 7 for longitudinal fixation and a second mounting component 8 for lateral fixation, ensures a stable connection between the heating component 3 and the mounting part 52. Longitudinal fixation effectively prevents the heating component 3 from detaching from the mounting part 52 under gravity. For example, when the ground brush 1 is tilted to clean the bottom of a wall, the heating component 3 will not sag due to its own weight and will always move synchronously with the mounting part 52. Furthermore, the simultaneous placement of the first mounting component 7 and the second mounting component 8 enhances the shock resistance of the heating component 3. When the ground brush 1 moves over a rough surface to be cleaned, even under significant vibration, the heating component 3 remains stably fixed to the mounting part 52, reducing the decrease in heating effect caused by loosening and extending the service life of the device.

[0108] Specifically, the heating assembly 3 has a mounting hole, the first mounting member 7 passes through the mounting hole and has a mounting part at the bottom of the mounting hole. The surface area of ​​the mounting part is larger than that of the mounting hole and fits against the lower surface of the heating assembly 3. The upper end of the first mounting member 7 has a through hole, and the second mounting member 8 passes through the through hole to mount the first mounting member 7 to the second mounting member 8. The end of the mounting part 52 includes two aligned connecting protrusions 521. The second mounting member 8 passes through the through holes on the two connecting protrusions 521 in sequence. One side of one connecting protrusion 521 is also provided with a limiting groove 140. One end of the second mounting member 8 is bent and located in the limiting groove 140. When it is necessary to remove the second mounting member 8, it is only necessary to rotate the second mounting member 8 so that its bent side is disengaged from the limiting groove 140, and then pull the second mounting member 8 out of the connecting protrusion 521. The first mounting member 7 can be pulled out from the mounting hole from below to separate the first mounting member 7 from the heating assembly 3.

[0109] Furthermore, such as Figure 7 As shown, the first mounting member 7 and the mounting portion 52 are in a clearance fit in the lateral direction. Specifically, the first mounting member 7 and the connecting protrusion 521 are in a clearance fit in the lateral direction.

[0110] The first mounting component 7 and the mounting part 52 are fitted with a lateral clearance. This design provides the heating component 3 with a certain lateral adjustment space, effectively compensating for dimensional deviations during production and use. During production and assembly, due to minor errors in part processing, the clearance fit allows the heating component 3 to be finely adjusted laterally, ensuring its precise alignment with the cleaning component 2 and reducing the probability of assembly difficulties or component damage caused by rigid connections. On the other hand, the existence of the lateral clearance between the first mounting component 7 and the mounting part 52 provides the heating component 3 with lateral displacement space. When the heating component 3 is in contact with the cleaning component 2, it may be affected by the frictional force of the rotation of the cleaning component 2, or when protruding dirt such as stone particles adheres to the outer surface of the cleaning component 2 and comes into contact with the heating component 3, the heating component 3 may be affected by the aforementioned forces and tend to move laterally relative to the cleaning component 2. The existence of the lateral clearance allows the heating component 3 to move to a certain lateral position under the action of external forces, realizing the lateral floating of the heating component 3 relative to the cleaning component 2, which helps to improve the adaptability of the heating component 3 to changes in the external working environment. Furthermore, the existence of the lateral gap between the first mounting member 7 and the mounting part 52 also provides space for the mounting part 52 to move laterally. When the mounting part 52 rotates around the pivot 51, both longitudinal and lateral displacements occur simultaneously. Since there is a lateral gap between the first mounting member 7 and the mounting part 52, only the mounting part 52 moves laterally and does not cause the heating component 3 to move laterally together with the mounting part 52. The heating component 3 only moves longitudinally, so that when the heating component 3 comes into contact with the cleaning member 2 again, it can still fit tightly with a large contact area, reducing the problem of poor fit between the cleaning member 2 and the heating component 3 due to inaccurate control during the displacement process.

[0111] Furthermore, when the internal components of the ground brush 1 undergo slight deformation due to wear, this clearance fit allows the heating assembly 3 to adaptively adjust its lateral position, ensuring it remains in close contact with the cleaning component 2. For example, if the surface of the cleaning component 2 shows slight wear after prolonged use, the heating assembly 3 can compensate for the wear through lateral fine-tuning, maintaining good heating contact. Simultaneously, the clearance fit reduces rigid friction between the heating assembly 3 and the mounting part 52. As the heating assembly 3 rotates with the mounting part 52, the small lateral movement space reduces wear between components, extends the service life of the heating assembly 3, and ensures stable heating even after long-term use.

[0112] Specifically, such as Figure 7 As shown, the first mounting member 7 is spaced apart from the two connecting protrusions 521 to form a lateral gap between the first mounting member 7 and the connecting protrusions 521 on both sides.

[0113] Example 3:

[0114] In this embodiment, with the use of the cleaning component 2, the lint on its surface may shed or flatten, potentially causing the heating component 3 to fail to adhere to the cleaning component 2 at positions where it should have been. Since the change in the outer diameter of the cleaning component 2 is extremely slight and constantly changing, adjusting the swing position of the swinging component 5 to ensure proper contact between the heating component 3 and the cleaning component 2 requires high precision. Therefore, this embodiment provides an installation structure for the heating component 3 that, without altering the mating positions of the triggering component 6 and the swinging component 5, ensures proper contact between the heating component 3 and the cleaning component 2 when the triggering component 6 is in its first position. Figure 8 , Figure 9 As shown, the heating assembly 3 also includes an inner support 32, an outer support 33, and a flexible sealing body 34 fixedly connected to the inner support 32 and the outer support 33 respectively. The inner support 32 has a mounting through hole extending along the length of the cleaning component 2. The heating component 31 is disposed in the mounting through hole and protrudes downward from the lower surface of the inner support 32 through the mounting through hole. A floating gap 150 exists between the inner support 32 and the outer support 33. The outer support 33 is fixed to the mounting cavity 111 of the floor brush 1 housing and fits against its inner wall. A heat insulation component 35 is also provided between the inner support 32 and the heating component 31.

[0115] The surface cleaning device also includes a cantilever bracket 160 fixedly connected to the heating component 3. At least a portion of the cantilever bracket 160 and the heating component 3 are located within the mounting cavity 111. The cantilever bracket 160 is fixedly connected to the inner bracket 32. The heating component 3 is floatingly mounted on the extension 4 via the cantilever bracket 160, and there is a heat dissipation gap between the heating component 3 and the extension 4.

[0116] The cantilever bracket 160 includes a suspension portion 1601 located at its top, and the extension portion 4 is provided with a mating portion that aligns with the suspension portion 1601. The suspension portion 1601 can move longitudinally relative to the mating portion to switch the heating assembly 3 between a position that is in contact with the cleaning component 2 or a position that is separate from the cleaning component 2.

[0117] Specifically, the cantilever bracket 160 includes a cantilever body 1602 extending horizontally, with two first connecting parts located on either side of the cantilever body 1602. A cantilever boss 1603 protrudes upwards in the middle of the cantilever body 1602, with a threaded hole inside the boss 1603. The suspension part 1601 is constructed as a bolt threadedly connected to the cantilever boss 1603, with a flange at the top. The extension part 4 has a protruding portion above the cantilever boss 1603, with an overlapping ring at the bottom. The top of the bolt is located inside the protrusion, and the flange overlaps with the overlapping ring. The top of the bolt can move up and down within the protrusion to accommodate the vertical movement of the heating assembly 3 and the inner bracket 32.

[0118] Furthermore, guide protrusions are provided on both sides of the cantilever body 1602, and the extension 4 has a guide groove extending downward in the vertical direction, with the guide protrusions located within the guide groove. The guide protrusions and guide grooves cooperate to guide the heating assembly 3 to move in the vertical direction.

[0119] An elastic reset member 170 is provided between the cantilever bracket 160 and the extension 4. The elastic reset member 170 can drive the cantilever bracket 160 and the heating assembly 3 to return from the position separated from the cleaning component 2 to the position in contact with the cleaning component 2. Further, the elastic reset member 170 is a spring.
