Description

Technical Field

[0001] The present application relates to the field of cleaning brushes, and in particular to a cleaning brush with steam spray. Background Art

[0002] The steam spray cleaning brush uses high-pressure steam to dissolve stains and sterilize. The penetrating power of steam molecules destroys the binding force between dirt and the surface, achieving the purpose of deep cleaning.

[0003] The existing steam spray cleaning brush consists of a steam spray pipe and a brush head. The steam spray hole of the steam spray pipe is exposed between the bristles of the brush head. High-pressure steam is sprayed toward the stains through the steam spray hole to accelerate the dissolution of the stains. The bristles on the brush head are then used to rub against the stains, thereby cleaning stubborn stains.

[0004] In the prior art, since the steam spray hole is buried inside the bristles, the steam sprayed from the steam spray hole will be disturbed by the bristles, resulting in a decrease in the pressure of the sprayed steam, affecting the cleaning effect of the stains; on the other hand, after the bristles come into contact with the stains, the stains will remain on the bristles. Over time, the stains will be transferred to the steam spray hole and block the steam spray hole. As time accumulates, the cleaning effect of the cleaning brush deteriorates, and the cleaning brush needs to be regularly maintained.

[0005] Therefore, how to design an efficient steam spray cleaning brush becomes a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0010] In an implementable embodiment, a limiting flange is provided at one end of the steam injection pipe away from the driving source, and the outer diameter of the limiting flange is greater than the inner diameter of the through hole.

[0011] In an implementable embodiment, the injection angle is between 5° and 20°.

[0012] In an implementable embodiment, the driving source includes a guiding cylinder, a sealing plate, a push rod, a push plate, and a spring. The guiding cylinder is provided on the head and recessed toward the inner cavity side. The sealing plate is slidably installed in the chamber of the guiding cylinder to form a sealed chamber. One end of the spring is fixedly connected to the sealing plate, and the other end of the spring is connected to the inner wall of the sealed chamber. The push rod is fixedly connected to the sealing plate and extends into the inner cavity of the head. The push plate is fixedly connected to the push rod. A number of steam injection pipes are installed on the push plate. A negative pressure port communicating with the sealed chamber is provided on the guiding cylinder, and a negative pressure source for providing a negative pressure environment for the sealed chamber is further included.

[0013] In an implementable embodiment, a negative pressure channel and an air delivery channel are further provided inside the handle. The negative pressure source is communicated with the sealed chamber through the negative pressure channel. The air delivery channel is communicated with the inner cavity of the head. A touch switch is further included. The touch switch is installed on the handle to simultaneously open or close the negative pressure channel and the air delivery channel.

[0014] In an implementable embodiment, a stain collection component is further included. The stain collection component is detachably installed on the head. The collection port of the stain collection component is aligned with the injection area.

[0015] In an implementable embodiment, the stain collection component includes a stain collection box. A collection channel communicating with the collection port is provided inside the stain collection box. A collection cavity is further included. The collection cavity is located inside the stain collection box and on one side of the collection channel to receive the dropped stain particles.

[0016] In one implementable embodiment, the bristles are detachably mounted on the head through a bristle plate. The bristle plate is rotatably mounted on the head through a first rotating shaft and switches between a first state and a second state.

[0017] Compared with the prior art, a cleaning brush with steam spraying of the present application has the following beneficial effects: In the present application, by using a steam spraying pipe with a steam inlet hole and a steam spraying hole, the steam to be sprayed in the inner cavity of the head is sprayed outwards, thereby realizing the cleaning of stains. The driving source drives the steam spraying pipe to switch between a standby state and an operating state, so as to be able to change the relative position between the steam spraying hole and the head. When the cleaning brush is in the operating state, the driving source pushes the steam spraying pipe to move, so that the steam spraying hole extends out of the through hole of the plugging seat, so that the steam spraying hole is exposed outside the head, thereby conveying the steam to be sprayed in the inner cavity of the head outwards. When the cleaning brush is in the standby state, at this time, the driving source drives the steam spraying pipe to retract, and the steam spraying hole is received into the through hole of the plugging seat to close the steam spraying hole, avoiding the plugging of the steam spraying hole by external stain particles and extending the maintenance period of the cleaning brush. The bristles are mounted on one side of the spraying area of the head, reducing the influence of the bristles on the spraying pressure of the steam to be sprayed, and at the same time being able to further reduce the stain particles on the bristles from entering the steam spraying hole. The axis of the steam spraying hole forms a spraying angle with the axis of the steam spraying pipe. Compared with the prior art in which the steam in the steam spraying hole is vertically sprayed onto the surface to be cleaned, the spraying angle of the present application will form an angle with the surface to be cleaned, reducing the risk of stain particles splashing into the bristles and the inside of the steam spraying hole, thereby being able to further extend the maintenance period of the cleaning brush.

[0022] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0023] like Figure 1 As shown, it includes a handle 1 and a head 2 which is detachably connected to the handle 1. Specifically, the handle 1 and the head 2 are assembled in a threaded connection. The handle 1 can be used to hold the cleaning brush, which is convenient for controlling the moving direction of the cleaning brush. The head 2 can be used to spray high-temperature and high-pressure steam onto the surface to be cleaned, so as to dissolve stubborn stain particles and enhance the cleaning effect of stubborn stains.

[0024] Specifically, Figure 2 As shown, a brush 22 for brushing off stains and a steam spray pipe 3 for spraying high-temperature and high-pressure steam can be installed on the head 2, and the steam sprayed from the steam spray pipe 3 can be used to dissolve stubborn stains.

[0025] A conventional cleaning brush with a steam spray function is provided with a steam spray pipe for spraying high-pressure and high-temperature steam, and is also provided with bristles 22 for cleaning dirt. The steam spray hole of the steam spray pipe is buried inside the bristles 22. The bristles 22 will affect the spray pressure of the steam. At the same time, during the cleaning process, stubborn stain particles will remain on the bristles 22. At this time, there is a risk of stains entering the steam spray hole, thereby causing the steam spray hole to be blocked. In order to maintain the cleaning effect of the cleaning brush, the cleaning brush needs to be maintained regularly.

[0026] To solve this problem, in this embodiment, Figure 2 and Figure 3As shown, the steam pipe 3 is installed in the inner cavity 20 of the head 2, and further includes a driving source 4 for driving the steam pipe 3 to switch between a standby state and an operating state. A sealing seat 5 is provided on the head 2, and a through hole 51 for the steam pipe 3 to pass through is provided on the sealing seat 5. Specifically, the steam pipe 3 adopts a hollow pipe structure with both ends sealed. Among them, the steam pipe 3 passes through the through hole 51, and the outer wall of the steam pipe 3 is slidably connected to the inner wall of the through hole 51 along the axial direction of the steam pipe 3; an inlet hole 31 and a steam hole 32 communicating with the cavity 30 of the steam pipe 3 are provided on the side wall of the steam pipe 3. Among them, the inlet hole 31 communicates with the inner cavity 20 of the head 2, and the inner cavity 20 is filled with high-pressure and high-temperature steam to be sprayed. In the operating state, as Figure 3 shown in the left schematic diagram, at this time, the driving source 4 pushes the steam pipe 3 to extend out of the head 2. At this time, the steam hole 32 on the steam pipe 3 is located outside the through hole 51, and the steam hole 32 is opened. The steam to be sprayed in the inner cavity 20 is sprayed outwards through the inlet hole 31 and the steam hole 32 to dissolve the stains. When the cleaning brush is in the standby state, at this time, the driving source 4 drives the steam pipe 3 to retract into the inner cavity 20 of the head 2. At this time, as Figure 3 shown in the right diagram, the steam hole 32 is located within the through hole 51, and the through hole 51 completes the sealing of the steam hole 32, which can solve the problem of blockage of the steam hole 32 caused by external stain particles.

[0027] It should be noted that in the operating state, since the pressure in the inner cavity 20 of the head 2 is greater than the external pressure, at this time, the steam to be sprayed in the inner cavity 20 continuously sprays outwards from the steam hole 32. During this process, stain particles cannot cause blockage of the steam hole 32.

[0028] Furthermore, in this embodiment, to solve the problem that the bristles 22 affect the steam spraying of the steam pipe 3, as Figure 4 shown, a spraying area 21 for installing the steam pipe 3 is provided on the head 2, and the bristles 22 are installed on one side of the spraying area 21 to avoid the influence of the bristles 22 on the spraying pressure of the sprayed steam.

[0029] Under normal circumstances, the steam sprayed out by the steam pipe 3 will be vertically sprayed on the surface of the object to be cleaned. At this time, the stubborn stains peeled off from the object to be cleaned will splash into the bristles 22 or the steam holes 32. When the stains remain on the bristles 22, when the bristles 22 clean the surface of the object, there is a risk that the stains will be transferred to the surface of the object again, resulting in incomplete cleaning; there is also a risk that the splashed stains will enter the steam holes 32.

[0030] Since both ends of the steam pipe 3 in this application are in a closed state and the steam holes 32 are provided on the side wall of the steam pipe 3, therefore, the steam in this application sprays outwards from the side of the steam pipe 3, reducing the risk of stains entering the steam holes 32.

[0031] In order to enable the steam ejected from the steam ejection holes 32 to be ejected onto the surface of the object to be cleaned, in this application, as Figure 3 shown, a diversion channel 35 communicating with the steam ejection holes 32 is further provided in the cavity 30 of the steam pipe 3. Among them, the axis of the diversion channel 35 forms an ejection angle 33 with the axis of the steam pipe 3. It should be noted that the ejection angle 33 refers to the angle with the vertical plane. Among them, the range of the ejection angle 33 is between 5° and 20°. The diversion channel 35 is used to guide the airflow inside the cavity 30 and then eject it outward from the steam ejection holes 32 to ensure that the ejected steam extends obliquely downward, so that the steam can be ejected onto the surface of the object to be cleaned.

[0032] Specifically, in this embodiment, the ejection angle 33 is 10°.

[0033] In order to fix the plugging seat 5, in this embodiment, as Figure 5 shown, an installation opening 23 is provided on the bottom wall of the head 2, and the installation opening 23 communicates with the inner cavity 20 of the head 2. As Figure 3 and Figure 4 shown, the plugging seat 5 is installed on the positioning component 6, and the positioning component 6 is used to plug the installation opening 23, thereby sealing the inner cavity 20 of the head 2. The positioning component 6 and the steam pipe 3 can be installed inward from the installation opening 23, which is convenient for assembling the cleaning brush.

[0034] Specifically, as Figure 3 shown, the positioning component 6 includes a first positioning plate 61 and a second positioning plate 62. Among them, the plugging seat 5 is clamped between the first positioning plate 61 and the second positioning plate 62, and the first positioning plate 61, the second positioning plate 62 and the bottom wall of the head 2 are fixedly connected by bolts, and the installation opening 23 is plugged through the first positioning plate 61.

[0035] Among them, as Figure 3 shown, a placement groove 621 is provided on the second positioning plate 62, and the plugging seat 5 can be installed in the placement groove 621. It should be noted that in this embodiment, the placement groove 621 is frustum-shaped, and the structure of the plugging seat 5 is the same as that of the placement groove 621. The outer wall of the plugging seat 5 abuts against the inner wall of the placement groove 621, thereby improving the installation stability of the plugging seat 5.

[0036] In the solution of using the first positioning plate 61 and the second positioning plate 62 to clamp the plugging seat 5, it is convenient to replace the damaged plugging seat 5.

[0037] In order to switch the steam pipe 3 between the standby state and the working state, in this embodiment, as Figure 6 and Figure 7As shown in the figure, the drive source 4 further includes a guide cylinder 40, a sealing plate 41, a push rod 42, a push plate 43, and a spring 44. Among them, the guide cylinder 40 is installed on the head 2 and extends into the inner cavity 20 of the head 2. One side of the guide cylinder 40 is open outward. The sealing plate 41 is installed inside the guide cylinder 40. The side wall of the sealing plate 41 is slidably connected to the inner wall of the guide cylinder 40 along the axis of the guide cylinder 40. Among them, the sealing plate 41 and the guide cylinder 40 form a sealed cavity 401. One end of the push rod 42 is fixedly installed on the sealing plate 41, and the other end of the push rod 42 extends through the guide cylinder 40 into the inner cavity 20. The push plate 43 is fixedly connected to the push rod 42. A plurality of steam pipes 3 are fixedly installed on the push plate 43. The spring 44 is sleeved outside the push rod 42. One end of the spring 44 is fixedly connected to the sealing plate 41, and the other end of the spring 44 is fixedly connected to the inner wall of the sealed cavity 401. The guide cylinder 40 is also provided with a negative pressure port 402 communicating with the sealed cavity 401, and further includes a negative pressure source connected to the negative pressure port 402 to form a negative pressure environment for the sealed cavity 401.

[0038] Through the above settings, the negative pressure source is used to extract the air inside the sealed cavity 401. At this time, the pressure in the sealed cavity 401 drops, forming an air pressure difference with the external air pressure. Thus, the sealing plate 41 begins to compress the spring 44. At the same time, the steam pipes 3 are pushed outwards from the inner cavity 20 through the push rod 42 and the push plate 43. Thus, the steam to be sprayed in the inner cavity 20 is sprayed out through the steam pipes 3, realizing the release of steam. When the negative pressure source stops extracting the air in the sealed cavity 401, the gas in the inner cavity 20 surges into the sealed cavity 401 through the gap between the guide cylinder 40 and the push rod 42. Under the elastic force of the spring 44, the steam pipes 3 are driven to move into the inner cavity 20. At this time, the steam holes 32 are blocked by the through holes 51, preventing the steam in the inner cavity 20 from being discharged outwards, so that the cleaning brush is maintained in the standby state.

[0039] When the negative pressure source provides a negative pressure environment for the sealed cavity 401, in order to prevent the air outside the head 2 from entering the sealed cavity 401, thereby transferring the external dust to the inner cavity 20 through the sealed cavity 401 and reducing the blockage of the steam pipes 3 caused by the external dust in the inner cavity 20. Therefore, in this embodiment, as Figure 6 and Figure 7 shown, it further includes a sealing ring 45. Among them, the sealing ring 45 is installed on the peripheral wall of the sealing plate 41. When the sealing plate 41 is placed in the guide cylinder 40, the outer wall of the sealing ring 45 abuts against the inner wall of the guide cylinder 40, strengthening the seal of the gap between the sealing plate 41 and the inner wall of the guide cylinder 40 and preventing the entry of external dust.

[0040] When the cleaning brush is in the standby state, as Figure 3As shown in the right-side schematic diagram, the steam jet hole 32 is located on the inner wall of the through hole 51 at this time and blocks the steam jet hole 32. Usually, the steam jet pipe 3 is in the shape of a cylindrical tube with a uniform thickness. Therefore, in the standby state, the end wall of the steam jet pipe 3 cannot block the end of the through hole 51 exposed on the outside, and there is still a risk that the stain particles peeled off from the object to be cleaned will enter the inside of the through hole 51, thus blocking the through hole 51. Therefore, in this embodiment, as Figure 3 shown, a limiting flange 34 is provided at one end of the steam jet pipe 3 away from the inner cavity 20. Among them, the outer diameter of the limiting flange 34 is greater than the inner diameter of the through hole 51. When the cleaning brush is in the standby state, the limiting flange 34 is used to block the end position of the through hole 51 at this time, preventing external stain particles from entering the through hole 51 and reducing the risk of the through hole 51 being blocked. At the same time, when the limiting flange 34 abuts against the end wall of the through hole 51, the steam jet pipe 3 stops extending further into the inner cavity 20.

[0041] In order to further limit the position of the steam jet pipe 3, as Figure 6 shown, it further includes a first limiting retaining ring 403 and a second limiting retaining ring 404. Among them, both the first limiting retaining ring 403 and the second limiting retaining ring 404 are installed on the inner wall of the guiding cylinder 40. When the cleaning brush is in the standby state, the sealing plate 41 abuts against the first limiting retaining ring 403. When the cleaning brush is in the working state, the sealing plate 41 abuts against the second limiting retaining ring 404. By restricting the position of the sealing plate 41, the position of the steam jet pipe 3 is further limited.

[0042] In order to provide a negative pressure environment for the sealing cavity 401 in the head 2, in this embodiment, as Figure 2 、 Figure 4 and Figure 6 shown, a negative pressure channel 11 connected to an external negative pressure source is provided on the handle 1. The negative pressure channel 11 is connected to the negative pressure port 402, thereby providing a negative pressure environment for the sealing cavity 401.

[0043] In order to provide high-temperature and high-pressure steam to be sprayed into the inner cavity 20 of the head 2, in this embodiment, as Figure 2 and Figure 4 shown, a gas transmission channel 12 is provided on the handle 1. One end of the gas transmission channel 12 is connected to an external steam source, and the other end of the gas transmission channel 12 is connected to the inner cavity 20 of the head 2.

[0044] The cleaning brush in this application is mainly used for cleaning cultural relics. Among them, the pressure of the high-temperature and high-pressure steam to be sprayed is between 0.3 Mpa and 4 Mpa, and the temperature of the steam is between 40 °C and 80 °C. The spraying pressure and the temperature of the steam can be adjusted adaptively according to different types of cultural relics.

[0045] After the steam ejected from the steam pipe 3 touches the surface of the cultural relic to be cleaned, the stains on the surface of the cultural relic will splash out under the action of the steam impact force. The splashing stain particles will fall onto the workbench or other positions of the cultural relic, making it inconvenient to handle the splashing stain particles. Therefore, in this embodiment, as Figure 2 shown, it further includes a stain collection assembly 8 installed on the bottom wall of the head 2. Among them, the negative pressure source is connected to the stain collection assembly 8 to provide a negative pressure environment for the stain collection assembly 8, so as to collect the stain particles peeled off from the surface of the cultural relic and prevent the peeled stain particles from splashing wantonly.

[0046] Specifically, in this embodiment, as Figure 4 shown, a splashing angle 26 is formed between the spraying area 21 and the horizontal plane, where the splashing angle 26 is between 5° and 25°. Specifically, the splashing angle 26 in this embodiment is 15°; when the steam to be sprayed is ejected from the steam hole 32 of the steam pipe 3, the steam will impact on the surface of the cultural relic to be cleaned towards the handle 1 side, and the impacted and fallen stain particles will splash towards the rear side of the handle 1.

[0047] It should be noted that, as Figure 4 and Figure 8 shown, the collection port 80 of the stain collection assembly 8 is in the same direction as the direction of stain splashing, so as to use the collection port 80 to collect the stain particles.

[0048] As Figure 8 shown, the stain collection assembly 8 includes a stain collection box 81. Among them, the stain collection box 81 is detachably installed on the bottom of the head 2, and a suction port 84 is provided on the stain collection box 81. The suction port 84 is connected to the negative pressure source, so as to be able to form a negative pressure inside the stain collection box 81 to realize the suction and collection of the splashing stain particles.

[0049] Furthermore, as Figure 8 shown, a collection channel 82 and a collection cavity 83 are further provided inside the stain collection box 81. Among them, one end of the collection channel 82 is connected to the collection port 80, and the other end of the collection channel 82 is connected to the suction port 84. The external stain particles flow along the collection channel 82 towards the suction port 84.

[0050] Furthermore, a barrier net is provided at the position of the suction port 84, and the collection cavity 83 is located directly below the barrier net. When the stain particles hit the barrier net, the stain particles will fall into the collection cavity 83 under the action of gravity to complete the collection of the stain particles.

[0051] After the cleaning brush finishes cleaning the cultural relic, the stain collection assembly 8 can be removed from the head 2, then the barrier net is removed, and the stain particles stored inside the collection cavity 83 are poured out from the suction port 84.

[0052] In order to provide a negative pressure to the suction port 84, in this embodiment, as Figure 2 and Figure 9 shown, one end of the negative pressure channel 11 close to the head 2 is connected with a bifurcated first negative pressure pipe 111 and a second negative pressure pipe 112. Among them, the first negative pressure pipe 111 is connected with the negative pressure port 402, and the second negative pressure pipe 112 is connected with the suction port 84.

[0053] Specifically, as Figure 4 shown, a buffer cavity 27 is separated in the inner cavity 20 of the head 2. A connection port 271 is provided on the buffer cavity 27, and the connection port 271 is connected with the second negative pressure pipe 112, and the buffer cavity 27 is used to connect with the suction port 84; after the second negative pressure pipe 112 is connected with the buffer cavity 27, the pressures at various points inside the buffer cavity 27 tend to be balanced, and then the buffer cavity 27 is used to connect with the suction port 84, so as to improve the stability of the suction force of the storage channel 82.

[0054] Since multiple steam pipes 3 are distributed on the spraying area 21, the range of splashing of stain particles on the cultural relics is relatively large. In order to improve the storage effect on the splashed particles, in this embodiment, as Figure 8 and Figure 10 shown, a curved diversion surface 85 is provided on one side of the stain storage box 81 facing the spraying area 21. A drainage port 86 communicating with the storage channel 82 is provided at the bottom of the diversion surface 85. The splashed stain particles caused by spraying steam through the steam pipe 3 are blocked by the diversion surface 85, and the sprayed steam condenses into water flow on the diversion surface 85, so as to wash the stain particles to the drainage port 86 at the bottom of the diversion surface 85, and then the negative pressure at the position of the storage channel 82 is used to suck the stain particles and the condensed water at the drainage port 86 into the stain storage box 81.

[0055] Since the air supply channel 12 is arranged on the handle 1, and the temperature of the steam transported by the air supply channel 12 is between 40°C and 80°C, when the user directly holds the handle 1, there is a risk of being scalded. Therefore, in this embodiment, as Figure 2 and Figure 9 shown, an isolation cavity 13 is provided on the handle 1 outside the air supply channel 12 to reduce the conduction of the heat inside the air supply channel 12 to the handle 1 and reduce the risk of the user being scalded.

[0056] When the cleaning brush is in use, in order to be able to control the steam to be sprayed by the steam pipe 3 and realize the recovery of the stain particles, in this embodiment, as Figure 2 and Figure 10 shown, a touch switch 7 for controlling the opening or closing of the negative pressure channel 11 and the air supply channel 12 is also provided on the handle 1. By adjusting the state of the touch switch 7, the steam in the handle 1 can be controlled to be transported to the head 2, and at the same time, the negative pressure environment in the sealing cavity 401 and the stain storage box 81 can be controlled.

[0057] It should be noted that the touch switch 7 controls the opening or closing of the negative pressure channel 11 and the gas transmission channel 12 simultaneously.

[0058] Specifically, as Figure 12 shown, a control cavity 71 is provided on the handle 1 at the middle position of the gas transmission channel 12. Among them, both ends of the control cavity 71 are communicated with the gas transmission channel 12. The diameter of the control cavity 71 is larger than that of the gas transmission channel 12. The control cavity 71 includes a sealing section 711 and an opening section 712. The sealing section 711 is on the side away from the head 2, and the opening section 712 is on the side close to the head 2. A plurality of diversion grooves 713 are provided on the peripheral wall of the opening section 712. A control valve 714 is slidably connected inside the control cavity 71. The outer wall of the control valve 714 abuts against the inner wall of the control cavity 71 at the sealing section 711 to close the gas transmission channel 12. When the control valve 714 is located behind the opening section 712, the gas transmission channels 12 on both sides of the control cavity 71 are communicated through the diversion grooves 713, thereby opening the gas transmission channel 12.

[0059] In this embodiment, when the control valve 714 switches between the sealing section 711 and the opening section 712, it needs to be realized through the pull rope 72 and the compression spring 73. A limiting block 715 is fixedly provided on the inner wall of the control cavity 71 at the opening section 712. One end of the compression spring 73 abuts against the limiting block 715, and the other end of the compression spring 73 abuts against the control valve 714. The pull rope 72 is connected to the control valve 714. By pulling the pull rope 72, the control valve 714 can be driven to compress the compression spring 73 to open the gas transmission channel 12. When the restriction on the pull rope 72 is released, at this time, the compression spring 73 pushes the control valve 714 to reset, thereby closing the gas transmission channel 12.

[0060] In order to open or close the negative pressure channel 11, in this embodiment, as Figure 12 shown, a sliding cavity 74 is provided on the handle 1, which is communicated with the negative pressure channel 11 and cuts off the negative pressure channel 11 in the middle. A sliding column 75 is slidably connected in the sliding cavity 74. A through hole 751 is provided on the sliding column 75, which can communicate the negative pressure channels 11 on both sides of the sliding cavity 74. When the through hole 751 is completely misaligned with the negative pressure channel 11, the supply of negative pressure from the outside to the head 2 is stopped. When the through hole 751 is aligned with the negative pressure channel 11, the negative pressure channel 11 is opened to provide a negative pressure environment for the head 2.

[0061] Among them, the pull rope 72 is fixedly connected to the sliding column 75, so as to realize the synchronous movement of the control valve 714 and the sliding column 75, and realize the simultaneous opening or simultaneous closing of the gas transmission channel 12 and the negative pressure channel 11.

[0062] It should be noted that the pull rope 72 is always in a taut state.

[0063] In order to ensure the stable sliding of the sliding column 75, a slider can be installed on the outer wall of the sliding column 75, and a sliding groove for inserting the slider is provided on the inner wall of the sliding cavity 74, thereby improving the stability of the movement of the sliding column 75, avoiding circumferential rotation of the sliding column 75 during the sliding process, and reducing the risk that the conducting hole 751 cannot connect the negative pressure channels 11 on both sides.

[0064] In order to realize the movement of the sliding column 75, in this embodiment, as shown in FIG. Figure 12 As shown, the touch switch 7 also includes a pressing handle 76, wherein the pressing handle 76 includes a gripping portion 761 and a pushing portion 762, and also includes a second rotating shaft 77. The pressing handle 76 is rotatably mounted on the outer wall of the handle 1 through the second rotating shaft 77, and the gripping portion 761 and the pushing portion 762 are respectively located on both sides of the second rotating shaft 77. The sliding column 75 extends out of the outer wall of the sliding cavity 74, and a toggle groove 752 for inserting the pushing portion 762 is provided, and the pushing portion 762 abuts against the bottom wall of the toggle groove 752.

[0065] When the pressing handle 76 is not pressed, the conducting hole 751 closes the negative pressure channels 11 on both sides, and the control valve 714 is located at the sealing section 711 to close the gas supply channel 12. When it is necessary to provide steam and a negative pressure environment to the head 2, the hand is held on the handle 1 and the gripping portion 761 of the pressing handle 76 is pressed. At this time, the pressing handle 76 rotates around the second rotating shaft 77, and the pushing portion 762 cooperates with the toggle groove 752 to toggle the sliding column 75 to the outside of the sliding cavity 74. The hole 751 connects the negative pressure channels 11 on both sides. During the movement of the sliding column 75, the control valve 714 is switched from the sealing section 711 to the opening section 712 through the pull rope 72 and the compression spring 73 is compressed. At this time, the guide groove 713 connects the gas supply channels 12 on both sides, thereby supplying steam to the inner cavity 20 of the head 2; when the restriction on the pressing handle 76 is released, the compression spring 73 pushes the control valve 714 to reset, and drives the sliding column 75 to move through the pull rope 72, thereby closing the negative pressure channel 11.

[0066] In order to realize the installation of the bristles 22, in this embodiment, as Figure 13 As shown, it also includes a bristle plate 24, on which the bristles 22 are fixedly mounted. The bristles 22 are detachably mounted on the bottom wall of the head 2 and located on one side of the spraying area 21 through the bristle plate 24. Figure 2 As shown, the bristles 22 and the stain collecting assembly 8 are respectively located on both sides of the spraying area 21 .

[0067] like Figure 5 and Figure 13As shown in the figure, a first rotating shaft 241 is provided on one side of the brush hair plate 24, and a limiting shaft 242 is provided on the other side. Among them, the axes of the first rotating shaft 241 and the limiting shaft 242 coincide. A plugging hole 281 for inserting the first rotating shaft 241 is provided on the head 2, and a limiting through groove 282 for placing the limiting shaft 242 is also provided. During the installation process, the brush hair plate 24 is inserted inward from the side of the head 2 through the limiting through groove 282 until the first rotating shaft 241 is inserted into the plugging hole 281. At this time, the limiting shaft 242 is located in the limiting through groove 282. At this time, the brush hair plate 24 is rotated around the first rotating shaft 241, and the brush hair plate 24 is flipped to a horizontal state.

[0068] As Figure 13 and Figure 14 shown in the figure, a locking member 25 is further provided on the brush hair plate 24. The brush hair plate 24 is locked on the head 2 by using the locking member 25, thereby completing the installation of the brush hair plate 24.

[0069] Specifically, the locking member 25 includes a locking hole 251 opened on the side wall of the head 2, a locking groove 252, a locking block 253 and a pushing spring 254 opened on the side wall of the brush hair plate 24. Among them, the locking block 253 is slidably installed in the locking groove 252. One end of the pushing spring 254 abuts against the inner wall of the locking groove 252, and the other end of the pushing spring 254 abuts against the locking block 253. When the brush hair plate 24 is in a horizontal state, the locking hole 251 is aligned with the locking groove 252. At this time, the locking block 253 is inserted into the locking hole 251, thereby realizing the locking of the brush hair plate 24.

[0070] Specifically, as Figure 14 shown in the figure, a first guiding surface 2531 and a second guiding surface 2532 are provided on the locking block 253. When the brush hair plate 24 is flipped towards the horizontal state, the first guiding surface 2531 first abuts against the bottom wall of the head 2, thereby pushing the locking block 253 into the locking groove 252 and compressing the pushing spring 254. When the brush hair plate 24 is in a horizontal state, the locking groove 252 is aligned with the locking hole 251. At this time, the pushing spring 254 will push the locking block 253 out and insert it into the locking hole 251. At this time, the top wall of the brush hair plate 24 abuts against the head 2, restricting the brush hair plate 24 from continuing to flip upwards.

[0071] Referring to Figure 14 shown in the figure, a groove for the brush hair plate 24 to be embedded is provided on the bottom wall of the head 2, and the locking hole 251 is provided on the side wall of the groove. When the brush hair plate 24 is in a horizontal state, the gap between the top wall of the brush hair plate 24 and the top wall of the groove is small, and it cannot meet the requirement for the brush hair plate 24 to continue to flip upwards around the first rotating shaft 241.

[0072] When the brush hair plate 24 is turned outwards from the groove for disassembling the brush hair plate 24 from the head 2, the second guiding surface 2532 will abut against the side wall of the locking hole 251, thereby pushing the locking block 253 into the locking groove 252 to release the locking between the brush hair plate 24 and the head 2, and the removal of the brush hair plate 24 can be realized.

[0073] In this embodiment, after the cleaning brush finishes cleaning the surface of the cultural relic, the stain particles remaining on the brush hairs 22 can be cleaned. At this time, the brush hair plate 24 can be switched between a first state and a second state. The first state is the state where the brush hair plate 24 is locked to the head 2. Referring to Figure 2 As shown, in the first state, the brush hairs 22 can complete the cleaning of the stain particles on the surface of the cultural relic; after the locking member 25 is unlocked from the head 2, the brush hair plate 24 is turned around the first rotating shaft 241 so that one end of the brush hair plate 24 away from the first rotating shaft 241 abuts against the guiding surface 85 of the stain receiving assembly 8. At this time, the brush hair plate 24 is inclined backwards by an angle, as Figure 9 shown. At this time, the steam ejected from the steam pipe 3 can clean the stain particles on the brush hairs 22, causing the stain particles to drop onto the guiding surface 85 and then flow into the drainage port 86 along the guiding surface 85 to complete the cleaning of the brush hairs 22.
