Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to cleaning equipment and a base assembly. Background Art

[0002] With the advancement of science and technology, in order to reduce people's labor intensity, cleaning equipment that can automatically clean the surface to be cleaned has emerged. The current cleaning equipment can not only clean the floor, but also clean the surface of carpets and other fabrics (for example, interior decorations).

[0003] In order to clean the surface of the blanket more thoroughly, the base assembly under the cleaning device is often equipped with a flat and long suction nozzle, which is conducive to getting close to the roots of the fabric's fluff and adsorbing the dust at the roots of the fluff. However, fluff, hair and other garbage are easy to adhere to the suction port and adsorption channel of the suction nozzle, which may cause the risk of clogging the suction port and adsorption channel in the long run, and long-term accumulation may breed bacteria and produce odor. The prior art is to set the suction nozzle at the bottom of the suction nozzle cover plate, and the suction nozzle and the suction nozzle cover plate are integrated into a suction nozzle assembly. The suction nozzle assembly is provided with a cover channel connecting the suction port and the adsorption channel. However, when the cleaning device is located on the blanket, there is a risk of clamping the fluff when the suction nozzle assembly is installed on the blanket. In addition, when the connection between the suction nozzle assembly and the base is poorly connected, the gap between the suction nozzle and the base during the movement of the cleaning device will also clamp the fluff, hindering the movement of the cleaning device. Utility Model Content

[0004] In view of the above problems, an embodiment of the utility model is proposed. The purpose of the embodiment of the utility model is to provide a cleaning device in which the suction nozzle and the seat body are reliably connected without any gap, and the adsorption channel, cover channel and suction port are easy to clean.

[0011] To achieve this purpose, the present invention adopts the following technical solutions:

[0012] A base assembly, comprising:

[0013] A seat body, a suction nozzle located at the bottom end of the front side of the seat body, and a suction nozzle cover plate abutting against the suction nozzle and movably arranged on the seat body;

[0014] The suction nozzle has a suction port, and the suction nozzle cover has a cover channel connected to the suction port, and the cover channel is connected to the suction mechanism through an adsorption channel. The technical solution provided by the embodiment of the utility model is to separately arrange the suction nozzle and the suction nozzle cover so that the connection between the suction nozzle cover and the base body will not affect the connection between the suction nozzle and the base body, thereby ensuring the reliability of the connection between the suction nozzle and the base body.

[0033] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solution in the embodiment of the present utility model is clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present utility model.

[0034] When practicing the embodiments of the utility model, the inventor found that the long and flat suction nozzle and the base assembly of the cleaning device for cleaning the surface of the fabric are either non-detachable, difficult to disassemble, or frequent disassembly will cause wear and breakage at the connection. Therefore, the user cannot or rarely cleans the suction nozzle and the suction nozzle cover during use. As the cleaning device is used for a longer time, dirt is easily accumulated on the lower surface of the nozzle cover and inside the suction nozzle air duct. If it is not cleaned and maintained, it is easy to cause troubles such as odor and blockage, and the user experience is very poor.

[0035] The reason is that the nozzle cover is not removable, or the nozzle cover and the nozzle are an integrated structure connected by a locking structure such as a buckle, a lock or a screw. In order to ensure that it is installed in place, a guide positioning structure is provided between the nozzle and the base body. When the cleaning device is cleaning the fabric surface, the base assembly will sink to the bottom of the fabric fluff, and the nozzle must be close to the root of the fluff or lower than the root of the fluff to properly cooperate with the guide positioning structure on the base assembly. This results in the nozzle and the nozzle cover being installed on the equipment body. The base assembly needs to be raised a certain distance, and the base assembly must be aligned with the guide positioning structure on the base assembly while being raised a certain distance. These two actions are difficult to perform at the same time, which can easily lead to improper assembly by the user and a poor user experience. In addition, if the nozzle and the nozzle cover are connected to the base assembly by screws, frequent disassembly will cause the screw hole to slip, thereby increasing the gap between the nozzle and the base assembly, or the nozzle falling off the base assembly.

[0036] In view of the above problems, an embodiment of the utility model provides a cleaning device to solve the problem that the suction nozzle and the suction nozzle cover are difficult to remove and install from the base assembly, and solves the problem of unreliable connection between the suction nozzle, the suction nozzle cover and the base assembly.

[0037] To this end, the utility model provides the following embodiments to solve or improve at least some of the above-mentioned problems. In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0038] In some features described in the specification, claims and the above-mentioned drawings of the utility model, descriptions such as "first" and "second" are used to distinguish different components, parts, modules, devices, etc., and do not represent the order of precedence, nor do they limit "first" and "second" to be different types. In addition, the embodiments described below are only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0039] Embodiment 1:

[0040] Figure 1 A partial cross-sectional structure diagram of a base assembly provided in an embodiment of the utility model Figure 1 , Figures 5 to 8 For a schematic diagram of the structure of the base assembly provided in different embodiments of the present invention, please refer to Figures 5 to 8 Any one of Figure 1 .

[0041] The present embodiment provides a cleaning device, which can clean the surface to be cleaned, including but not limited to fabric surface, floor surface, desktop, leather surface, etc. The cleaning device includes a device body and a base assembly 100 arranged at the bottom of the device body, and a suction mechanism is provided on one of the device body and the base assembly 100. The base assembly 100 is used to abut against the surface to be cleaned, and the base assembly 100 has a suction port at the abutment point with the surface to be cleaned. The suction port is connected to the suction mechanism through a suction channel 102. The suction mechanism can form a negative pressure in the suction channel 102, so that the external airflow enters the suction channel under the action of the negative pressure, and the airflow can drive the dirt on the surface to be cleaned into the suction channel 102 during the flow process.

[0042] In order to facilitate the collection of dirt on the surface to be cleaned, as a feasible embodiment, a dirt collecting box is provided on the device body or the base assembly 100. The dirt collecting box is arranged on the adsorption channel 102 and is located on the path of the airflow. The dirt that enters the adsorption channel 102 along with the airflow will be gathered in the dirt collecting box.

[0043] In order to prevent dirt from following the adsorption airflow out of the dirt collecting box and affecting the suction mechanism, as a feasible embodiment, a filter plug that blocks dirt from passing through but allows air to pass through is provided on the dirt collecting box, thereby preventing the adsorbed dirt from escaping from the dirt collecting box.

[0044] When the cleaning device is cleaning a fabric surface, since there may be long fluff on the fabric surface, such as a carpet, etc., in order to ensure the cleaning effect, the base assembly 100 will be buried in the fluff. For ease of operation, the user often directly places the cleaning device on the fabric surface, which will cause the base assembly 100 to directly press the fluff on the fabric surface underneath, so that the base assembly 100 cannot directly contact the roots of the fluff, which is not easy to clean, thus affecting the cleaning effect.

[0045] To solve the above problems, please refer to Figure 5 As an achievable embodiment, the base assembly 100 includes a base body 110 and a suction nozzle 120 located at the bottom front end of the base body 110. The suction nozzle 120 is in a flat and long shape and has a suction port 121. The suction port 121 is connected to the suction channel 102, that is, the suction port 121 is the suction port. When the base assembly 100 moves with the push of the user, the head of the flat and long suction nozzle 120 will push the fluff away and abut against the root of the fluff when it abuts against the fluff on the surface of the fabric, so that the suction port 121 can face the root of the fluff, and the adsorption force generated by the suction mechanism can act on the root of the fluff, so that the dirt at the root of the fluff can follow the adsorption airflow into the dirt collecting box, achieving a good cleaning effect.

[0046] There are a lot of hair or solid particles mixed in the dirt adsorbed by the cleaning device during operation. When these hair or solid particles enter the suction port or flow in the adsorption channel, they may adhere to the wall of the suction port or adhere to the adsorption channel 102. As the user continues to use the cleaning device to clean the surface, the hair or solid particles gradually gather in the adsorption channel 102. When a certain amount is reached, there is not only a risk of clogging the suction port 121 or the adsorption channel 102, but also bacteria may grow in the adsorption channel 201 or the suction port 121, thereby producing odor.

[0047] In order to solve the above problems, in some achievable embodiments of the present invention, a structure of the seat assembly 100 that can be implemented is that it also includes a nozzle cover plate 130, which is in contact with the nozzle 120 and can be movably arranged on the seat 110. The nozzle cover plate 130 is provided with a cover plate channel 101, one end of which is connected to the suction port and the other end of which is connected to the adsorption channel 102. After the cleaning device has been working for a period of time, the nozzle cover plate 130 can be operated to shift relative to the seat 110 to expose the cover plate channel 101 and the adsorption channel 102, and the cover plate channel 101 and the adsorption channel 102 can be cleaned and then reset.

[0048] Specifically, in some achievable embodiments of the present invention, a possible connection relationship between the nozzle cover plate 130 and the base 110 is that the top of the nozzle cover plate 130 can be rotatably disposed on the base 110. When the nozzle cover plate 130 needs to be cleaned, the user can operate the nozzle cover plate 130 to rotate the top of the nozzle cover plate 130 relative to the base 110, thereby exposing the openings of the cover channel 101 and the adsorption channel 102. At this time, the user can use a water spray gun to flush water into the cover channel 101 and the adsorption channel 102 for cleaning. Of course, one side or the bottom of the nozzle cover plate 130 can also be rotatably disposed on the base 110, as long as the nozzle cover plate 130 can be displaced relative to the base 110 to expose the openings of the cover channel 101 and the adsorption channel 102.

[0049] In some feasible embodiments of the present invention, another feasible connection relationship between the nozzle cover 130 and the base 110 is that the nozzle cover 130 is detachably arranged on the base 110. When the adsorption channel 102 needs to be cleaned, the user can remove the nozzle cover 130 from the base 110, and can take the nozzle cover 130 under the faucet to rinse the cover channel 101, and then put it back after cleaning.

[0050] Figure 2 A partial cross-sectional structure diagram of a base assembly provided in an embodiment of the utility model Figure 5 , Figure 3 A schematic diagram of the structure of a nozzle cover plate provided in an embodiment of the utility model. Figure 4 For a schematic diagram of the structure of the base assembly provided in one embodiment of the utility model, please refer to Figure 2 to Figure 4 .

[0051] Since the nozzle cover 130 has a certain curvature and a certain width, if a spray cleaning method is adopted, the sprayed clean water will collide with the channel arm of the cover channel 101 at the curvature to reduce the spray force, thus causing the problem of unclean cleaning.

[0052] In order to solve the above problems, in some achievable embodiments of the present invention, a achievable structure of the nozzle cover 130 is that the nozzle cover 130 includes a cover body 133 and a nozzle flap 134 that can be set on the cover body 133, the nozzle flap 134 and the cover body 133 are arranged to form a cover channel 101, the bottom end of the nozzle flap 134 can be rotatably set at the lower end of the cover body 133 to open or close the cover channel 101, the bottom end of the cover body 133 has a connecting port 135 connected to the cover channel 101, the connecting port 135 is connected to the suction port, and the first sealing member 131 is arranged around the connecting port 135. When cleaning the cover channel 101, the cover body 133 can be rotated to separate the cover body 133 from the nozzle cover to open the cover channel 101. When cleaning, the channel wall of the cover channel 101 can be fully brushed to ensure that the cover channel 101 can be cleaned thoroughly and avoid the adhesion of stubborn stains.

[0053] Furthermore, in order to avoid a stable connection between the cover body 133 and the nozzle flap 134 and to prevent the two from detaching from each other due to non-human factors, as an optional solution, a locking assembly 138 is provided between the cover body 133 and the nozzle flap 134. The locking assembly 138 is located at the center of the upper end of the cover body and the nozzle flap 134 to ensure the stability of the locking and prevent deflection.

[0054] Specifically, as an optional solution, the locking assembly 138 includes a locking member 1381, a locking slot 1383 and a return member 1382, one end of the return member 1382 is connected to the locking member 1381, and the other end is connected to one of the cover body 133 and the suction nozzle flap 134, the locking slot 1383 is arranged on the other of the cover body 133 and the suction nozzle flap 134, the return member 1382 has a certain compression deformation, the locking member 1381 can move within the range that the return member 1382 can recover, the locking slot 1383 is located on the return path of the return member 1382, the locking member 1381 has a wrench extending to the outside, and the user can drive the locking member 1381 to move in the direction of compressing the return member 1382 by moving the wrench. At this time, the return member 1382 is moved out of the locking slot 1383, thereby achieving unlocking of the cover body 133 and the suction nozzle flap 134. When the user releases the wrench, the locking member 1381 moves toward the locking groove 1383 under the action of the restoring force of the restoring member 1382 until it abuts against the groove wall of the locking groove 1383 to achieve locking between the cover body 133 and the suction nozzle flap 134.

[0055] In order to ensure the sealing of the cover channel 101, as an optional solution, the nozzle cover also includes a third sealing member 139, which is arranged on the circumference of the nozzle flap 134 facing the cover body 133 and abuts against the cover body 133 to seal the suction channel. The third sealing member 139 can be made of rubber. The sealing member made of rubber has good sealing effect and low cost.

[0056] In another embodiment, when the locking assembly 138 is unlocked, the nozzle flap 134 can be removed from the cover body 133 , and after the user removes the nozzle flap 134 , the nozzle flap 134 and the cover body 133 can be rinsed separately.

[0057] In order to enable the user to clean the cleaning equipment more efficiently, as a feasible embodiment, the suction nozzle 120 can also be set on the suction nozzle cover 130, that is, the suction nozzle 120 and the suction nozzle cover 130 are integrated into a suction nozzle assembly. When the suction nozzle assembly is removed from the base 110 and the user takes the suction nozzle assembly under the faucet for cleaning, the cover channel 101 and the suction port 121 can be cleaned at the same time.

[0058] Figure 5 This is a schematic diagram of the structure of a base assembly provided in one embodiment of the utility model. Figure 6 This is a schematic diagram of the structure of a cleaning device provided by an embodiment of the utility model. Figure 7 For a schematic diagram of the structure of an external device connected to a cleaning device according to an embodiment of the utility model, please refer to Figure 2 to Figure 7 In some achievable embodiments of the present invention, the nozzle cover 130 further includes an accessory socket cover 136. The nozzle cover 130 has an accessory socket 137 whose one end is connected to the adsorption channel 102 and the other end is connected to the outside. The accessory socket cover 136 is covered at the accessory socket 137 to block or open the accessory socket 137. External equipment can be connected to the adsorption channel 102 through the accessory socket 137. The suction mechanism provides adsorption force to the external equipment through the adsorption channel 102. The external equipment can use the adsorption force to adsorb the solid waste on the surface to be cleaned and place it in the dirt collection box through the adsorption channel.

[0059] The accessory socket cover 136 has a protruding handle to facilitate the removal of the accessory socket cover 136 from the accessory socket 137. In addition, when unlocking the nozzle flap 134 and the cover body 133, four fingers can be used to pull the handle and the thumb can be used to apply force to the wrench to drive the locking member 1381 to compress the return member 1382 to unlock the locking assembly 138, thereby realizing the one-handed opening of the cover channel 101, which is simple to operate.

[0060] As an optional solution, the accessory socket cover 136 has a fifth sealing member, which abuts against the circumference of the accessory socket 137 to seal the accessory socket 137 .

[0061] When the cleaning device is placed on the surface to be cleaned, such as a long-pile carpet, when the user removes the cover assembly for cleaning and then installs it back, the fluff of the long-pile carpet will be clamped between the cover assembly and the base 110, and in order to obtain a better cleaning effect, the suction port 121 is as close to the surface to be cleaned as possible, so the suction nozzle 120 almost contacts the surface to be cleaned. When the cover assembly is installed back after cleaning, the user needs to lift the base 110 and then install the cover assembly, which is inconvenient to operate.

[0062] To solve the above problems, please refer to Figure 8 to Figure 11 As an achievable embodiment, the nozzle 120 is disposed on the base 110, the bottom end of the nozzle cover 130 abuts against the nozzle 120, and the nozzle cover 130 is detachably connected to the base 110 via a latch assembly 140. Due to the elongated shape of the nozzle 120, the fluff of the blanket can be pressed under the nozzle 120, so that the fluff can be prevented from being sandwiched between the nozzle cover 130 and the base 110 when the nozzle cover 130 is installed on the base 110. In addition, by separately arranging the suction nozzle 120 and the suction nozzle cover 130, the disassembly and installation between the suction nozzle cover 130 and the base 110 does not affect the connection relationship between the suction nozzle 120 and the base 110, thereby ensuring the reliability of the connection between the suction nozzle 120 and the base 110, and preventing the suction nozzle 120 and the base 110 from having a gap due to failure or poor connection between the suction nozzle assembly and the base 110, thereby preventing the cleaning device from being caught by fluff during the movement of the surface to be cleaned. In addition, the separation and locking between the suction nozzle cover 130 and the base 110 can be achieved by operating the latch assembly 140 to unlock or lock, and the structure is simple, so that the suction nozzle cover 130 can be easily disassembled for cleaning and then reassembled. After the suction nozzle cover 130 is disassembled, the user can also clean the suction port 121 of the suction nozzle 120, and the cleaning method includes but is not limited to cleaning with a brush, spraying water toward the suction port 121 with a nozzle, etc. This ensures that no dirt will accumulate in the cover channel 101 and at the suction port 121, and ensures that the normal use of the cleaning equipment will not block the adsorption channel 102. Of course, as an achievable embodiment, the suction nozzle 120 can also be detachably arranged on the base body 110. When the suction nozzle 120 needs to be cleaned, the suction nozzle 120 can be removed from the base body 110, and then installed back on the base body 110 after cleaning. When the front end opening 112 is installed on the base body 110 and it is inconvenient to clean the dirt from the suction port 121, the suction nozzle 120 can be removed from the base body 110 for cleaning. This can greatly reduce the number of times the suction nozzle 120 is disassembled and assembled on the body, delay the wear of the connection between the suction nozzle 120 and the base body 110, and ensure the service life.

[0063] The cleaning equipment mentioned above includes but is not limited to carpet cleaners, vacuum cleaners, floor scrubbers, upright suction equipment, canister equipment, portable suction machines or commercial suction machines, etc.

[0064] Fig.12 For a schematic diagram of the structure of the lock pin and the reset member provided in one embodiment of the utility model, please refer to Fig.12 .

[0065] Further, in some achievable embodiments of the present invention, one achievable manner of the latch assembly 140 is that the latch assembly 140 includes a matching lock pin 141, a lock port 142, and a reset member 143 connected to the lock pin 141. The reset member 143 and the lock pin 141 are located on one of the base 110 and the nozzle cover 130, and the lock port 142 is located on the other. The lock pin 141 can move within the resettable range of the reset member 143, and the lock port 142 is located on the reset path of the lock pin 141. The lock pin 141 can be disengaged from the lock port 142 during the movement, thereby unlocking the nozzle cover 130 from the base 110. The reset member 143 must pass through the lock port 142 when resetting, and the lock pin 141 is inserted into the lock port 142 when passing through the lock port 142, thereby locking the nozzle cover 130 from the base 110, which has a simple structure and is easy to operate. As an optional solution, please refer to Figure 8 to Figure 11 , the lock pin 141 and the reset member 143 are located on the nozzle cover 130, and the lock port 142 is located on the base 110; or the lock pin 141 and the reset member 143 are located on the base 110, and the lock port 142 is located on the nozzle cover 130. As long as the lock pin 141 and the lock port 142 can cooperate to lock or unlock the nozzle cover 130 and the base 110, this embodiment is not specifically limited. As an optional solution, please refer to Fig.12The reset member 143 is a spring or a retaining spring. The reset member 143 is a spring and the reset member 143 and the locking pin 141 are located on the nozzle cover 130. One end of the spring is connected to the locking pin 141, and the other end of the spring is connected to the nozzle cover 130. The locking pin 141 can move along the direction of spring compression to compress the spring, thereby separating the locking pin 141 from the locking port 142. At this time, the nozzle cover 130 is unlocked from the seat body 110, and the nozzle cover 130 can be separated from the seat body 110. When the nozzle cover 130 is cleaned and aligned with the seat 110, the elastic force of the spring drives the spring to reset the lock pin 141. The lock pin 141 passes through the lock port 142 and is accommodated in the lock port 142. At this time, the spring has not yet returned to its natural state and still has a certain elastic force. Under the action of the elastic force, the lock pin 141 is pressed against the lock port 142, thereby locking the nozzle cover 130 and the seat 110, and preventing the nozzle cover 130 from separating from the seat 110. Of course, the reset member 143 can also be made of a material with elastic rubber material. As long as it has a certain displacement and can drive the pin lock to reset, this embodiment does not make specific limitations. In order to allow the lock pin 141 to smoothly enter the lock port 142 and avoid being restricted by the lock port 142, as an achievable embodiment, please refer to Figure 8 to Figure 11 In any one of them, the end surface where the locking pin 141 cooperates with the locking opening 142 is a guide surface 1411 , and under the action of the guide surface 1411 , the locking pin 141 can smoothly slide into the locking opening 142 .

[0066] In order to facilitate the movement of the locking pin 141 , as a feasible embodiment, a handle is further provided on the locking pin 141 , and the operator can move the locking pin 141 by turning the handle, which is easy to operate.

[0067] As an achievable embodiment, there are multiple latch assemblies 140, and the connection strength of the multiple latch assemblies 140 is higher, and the stable connection between the nozzle cover plate 130 and the base 110 is ensured, and the nozzle cover plate 130 can be prevented from falling off or deflecting from the base 110 unintentionally. The handles on the lock pins 141 of the multiple latch assemblies 140 can be linked, and the operator only needs to operate the unlocking button to unlock or lock all the latch assemblies 140. As an achievable embodiment, the handles of the multiple latch assemblies 140 unlocked in one direction are connected to a linkage rod, and the end of the linkage rod forms an unlocking button. The operator pushes the end of the linkage rod to unlock or lock the multiple latch assemblies 140.

[0068] As the best embodiment, please refer to Figure 8 to Figure 11Any one, there are two latch assemblies 140, and the two latch assemblies 140 are arranged on both sides of the connection between the nozzle cover plate 130 and the base body 110. When unlocking the nozzle cover plate 130 and the base body 110, the operator only needs to use the thumb and index finger of one hand to respectively contact the handles on the two latch assemblies 140 and apply a pinching force to bring the two handles closer together to achieve unlocking of the two latch assemblies 140, and release the handle to achieve locking of the two latch assemblies 140. The structure is simple and easy to operate. The arrangement of the two latch assemblies 140 can not only ensure the smooth installation of the nozzle cover plate 130 on the base body 110, but also ensure the connection strength.

[0069] In this embodiment, please refer to Figure 3 and Figure 4 , both sides of the upper end where the nozzle cover plate 130 abuts against the base body 110 are provided with latch assemblies 140. Since the docking interface between the cover channel 101 and the suction channel 102 is located at the upper end of the nozzle cover plate 130, the latch assemblies 140 are arranged at the upper end of the nozzle cover plate 130 closer to the docking interface, so that the cover channel 101 and the suction channel 102 can dock stably without displacement between the two, thereby ensuring the suction effect.

[0070] In the present embodiment, both sides of the upper end of the nozzle cover plate 130 have a lock port 142, and correspondingly, both sides of the abutment between the seat body 110 and the upper end of the nozzle cover plate 130 have a lock pin 141 that cooperates with the lock port 142. In order to facilitate user operation, the latch assembly 140 also includes a press-release member 144, by pressing the press-release member 144, the lock pin 141 can be driven to move toward the direction of the compression reset member 143 to move out of the lock port 142 and retract into the seat body 110, thereby realizing the unlocking between the nozzle cover plate 130 and the seat body 110. Release the press-release member 144, and the press-release member 144 is reset. At this time, the lock pin 141 extends out of the seat body 110 under the reset elastic force of the reset member 143. Since there are two latch assemblies, when removing the nozzle cover plate 130 from the seat body 110, the user needs to press the press-release member 144 with both hands at the same time, which is simple to operate. Furthermore, different operation modes can be used to distinguish the disassembly between the nozzle cover plate 130 and the base body 110 and the disassembly between the cover plate body 133 and the nozzle flap 134 .

[0071] Specifically, as an optional solution, the push-unlocking member 144 has a first guiding slope, and the lock pin 141 has a second guiding slope. The first guiding slope abuts against the second guiding slope. When the push-unlocking member 144 moves downward, the first guiding slope imparts a force to the second guiding slope toward the seat body, thereby driving the lock pin 141 to retract into the seat body 110. When the pressing force disappears, the lock pin 141 extends out of the seat body 110 under the action of the reset member 143. In this process, the second guiding slope imparts an upward force to the first guiding slope, so that the second guiding slope and the first guiding slope are relatively displaced, while driving the push-unlocking member 144 to reset. The structure is simple. In some feasible embodiments of the present invention, another feasible way of implementing the latch assembly 140 is that the latch assembly 140 includes a first magnetic component and a second magnetic component, wherein the first magnetic component is arranged on the nozzle cover 130, and the second magnetic component is arranged on the base 110 corresponding to the first magnetic component. When the nozzle cover 130 and the base 110 need to be unlocked, the second magnetic component or the first magnetic component is controlled to be demagnetized, so that the force between the first magnetic component and the second magnetic component disappears. At this time, the nozzle cover 130 and the base 110 are unlocked, or the user can apply a force greater than the magnetic attraction force to the nozzle cover 130 to unlock the nozzle cover 130 and the base 110. The nozzle cover 130 can be removed from the base body 110 for cleaning. After the nozzle cover 130 is cleaned and aligned with the base body 110, the second magnetic component or the first magnetic component is controlled to be magnetized. At this time, there is a magnetic attraction force between the second magnetic component and the first magnetic component, and the nozzle cover 130 cannot be removed from the base body 110, so the nozzle cover 130 and the base body 110 can be locked.

[0072] As an achievable embodiment, one of the first magnetic attraction member and the second magnetic attraction member is an electromagnet, and the other is a magnet or a metal block that can generate suction when in contact with a magnet, such as a steel block or an iron block. The electromagnet can be magnetized by charging the electromagnet, and the electromagnet can be demagnetized by powering off the electromagnet, which is easy to operate. As a preferred embodiment, the second magnetic attraction member located on the base 110 is an electromagnet, and the second magnetic attraction member can be coupled to a power source device on the base 110 or the equipment body, and the power source device provides electrical energy to the second magnetic attraction member. Of course, the first magnetic attraction member located on the nozzle cover 130 can also be an electromagnet, and a battery coupled to the first magnetic attraction member is provided on the nozzle cover 130.

[0073] In some achievable embodiments of the present invention, another achievable manner of the latch assembly 140 is that a groove is provided on the base 110, and a card block is provided on one of the upper groove walls of the groove and the upper part of the nozzle cover plate 130, and a card slot that matches the card block is provided on the other, and the lower ends of the base 110 and the nozzle cover plate 130 also match the card block and the card slot assembly. It can be understood that whether the nozzle cover plate 130 is made of plastic or metal, it itself has a certain amount of elastic deformation, and can be compressed a certain distance or stretched a certain distance. In order to ensure that the nozzle cover plate 130 and the periphery of the base 110 can be tightly pressed, a certain pulling force is applied to the nozzle cover plate 130 here, so that it is in a stretched state, and a certain tension is generated inside the nozzle cover plate 130. When the upper and lower ends of the nozzle cover 130 are connected to the base 110, the nozzle cover 130 itself will apply a certain force to the base 110 at the point of contact with the base 110 in order to resist the internal tension, so that the nozzle cover 130 can be tightly pressed against the base 110 and remain locked with the base 110 under the action of its own tension. It can be understood that the distance between the connection points on the base 110 that are connected to the upper and lower parts of the nozzle cover 130 is greater than the height of the nozzle cover 130, but is within the range of the elastic deformation of the nozzle cover 130. In other words, the nozzle cover 130 cannot reach the upper and lower connection points connected to the base 110 in the natural state. Only when the nozzle cover 130 is stretched a certain distance so that the nozzle cover 130 is in an elastically stretched state can it be installed on the base 110. In this way, a locking component specifically for locking the nozzle cover 130 to the base 110 can be saved, parts can be saved, and the structure can be more compact.

[0074] In order to facilitate the alignment of the nozzle cover 130 with the base 110, as an achievable embodiment, please refer to Figure 8 and Fig. 9 At least one set of pre-positioning components 150 that cooperate with each other are provided on the nozzle cover plate 130 and the base body 110 to limit the position of the nozzle cover plate 130 installed on the base body 110 and guide the alignment of the latch component 140 between the nozzle cover plate 130 and the base body 110. When the nozzle cover plate 130 is installed on the base body 110, the positioning component is operated to cooperate and connect first. At this time, there is no need to perform additional operations to align the nozzle cover plate 130 with the base body 110, and the nozzle cover plate 130 and the base body 110 can be accurately installed, which is convenient for users to operate.

[0075] Specifically, in some practicable embodiments of the present invention, please refer to Figure 8 or Figure 3One possible implementation of the pre-positioning assembly 150 is that the pre-positioning assembly 150 includes a first positioning member 151 and a second positioning member 152 that match each other. The first positioning member 151 is disposed on the nozzle cover plate 130, and the second positioning member 152 is disposed on the base 110 or the nozzle 120. The first positioning member 151 can rotate around the second positioning member 152 or the first positioning member 151 can move along the second positioning member 152. When the nozzle cover plate 130 is connected to the base 110, the first positioning member 151 and the second positioning member 152 are first aligned and installed. After installation, the nozzle cover plate 130 is operated to drive the first positioning member 151 to rotate or move around the second positioning member 152 to achieve accurate positioning of the nozzle cover plate 130 on the base 110, and the operation is simple.

[0076] In some practicable embodiments of the present invention, please refer to Figure 8 One possible way to realize the first positioning member 151 and the second positioning member 152 is that the first positioning member 151 is a card block with a certain arc, and a groove is correspondingly arranged on the base body 110 corresponding to the position of the first positioning member 151, and the second positioning member 152 is a limiting rod connecting the two opposite sides of the groove, and a limiting space is formed between the inner surface of the groove connecting the two opposite sides of the groove and the limiting rod, and the first positioning member 151 is inserted into the limiting space, and the arc-shaped card block can rotate around the limiting rod to realize the rotation of the nozzle cover 130 relative to the base body 110. At this time, the driving lock pin 141 moves along the direction of the compression reset member 143 to prevent the lock pin from hindering the rotation of the nozzle cover 130. When the nozzle cover 130 rotates to abut against the base body 110, the nozzle cover 130 and the base body 110 are precisely positioned. At this time, the locking pin 141 is released, and the locking pin 141 is inserted into the locking opening 142 under the action of the resetting member 143 , and the latch assembly 140 locks the nozzle cover 130 on the base body 110 .

[0077] In some practicable embodiments of the present invention, please refer to Figure 3 Another possible way to realize the first positioning member 151 and the second positioning member 152 is that the first positioning member 151 is an insert block arranged at the lower end of the suction nozzle cover 130, and the second positioning member 152 is a slot arranged on the suction nozzle 120, and the insert block cooperates with the slot. When the insert block is inserted into the slot and inserted to the bottom of the slot along the slot, the suction nozzle cover 130 and the base body 110 are accurately positioned, with a simple structure and easy operation.

[0078] When installing the suction nozzle cover 130 on the base 110, first align the first positioning member 151 with the second positioning member 152 and insert it. During the insertion process, drive the locking pin 141 to move along the direction of the compression reset member 143 to prevent the locking pin from hindering the suction nozzle cover 130 from moving downward. When the first positioning member 151 is inserted to the predetermined position of the second positioning member 152, release the locking pin 141. Under the action of the reset member 143, the locking pin 141 is inserted into the locking port 142, and the latch assembly 140 locks the suction nozzle cover 130 on the base 110.

[0079] Since the dirt on the surface to be cleaned is sucked into the dirt collection box by the suction force of the suction mechanism when cleaning the surface to be cleaned, the better the sealing performance of the adsorption channel 102 is, the stronger the adsorption force on the surface to be cleaned is. Figure 8 to Figure 11 In any one of them, a first sealing member 131 is provided on the nozzle cover 130 where it abuts against the nozzle 120 to avoid a gap between the nozzle cover 130 and the nozzle 120 due to the separation, thereby ensuring the sealing between the nozzle cover 130 and the nozzle 120.

[0080] Similarly, as an achievable embodiment, please refer to Figure 8 to Figure 11 In any one of the embodiments, the second sealing member 132 is provided at the abutment between the nozzle cover plate 130 and the base body 110. The second sealing member 132 can be provided on the nozzle cover plate 130 or on the base body 110. As long as the sealing between the nozzle cover plate 130 and the base body 110 can be achieved, this embodiment does not make any specific limitation. For example, the first sealing member 131 and the second sealing member 132 can be made of rubber material. The rubber material has a weak texture, a certain elastic deformation, a good sealing effect, and a low cost.

[0081] It is understandable that in order to strictly seal the nozzle cover 130 and the base body 110, the first seal 131 needs to be compressed and deformed. At this time, the first seal 131 will give a force along the reset direction of the first seal 131 under the action of its own elastic restoring force. Although the pre-positioning component 150 can limit the position of the nozzle cover 130, the limited direction is different from the force given to the nozzle cover 130 by the first seal 131 when it is reset. Therefore, the nozzle cover 130 will still shift under the action of the reset force of the first seal 131.

[0082] To avoid the above problems, please refer to Figure 2 to Figure 4In some achievable embodiments of the present invention, a vertical limiting structure 170 is provided at the abutment point between the nozzle cover plate and the nozzle to limit the position of the nozzle cover plate in the vertical direction. Since the first seal 131 is located at the bottom end of the nozzle cover plate 130, in order to achieve a better sealing effect of the first seal 131, the abutment surface between the nozzle cover plate 130 and the nozzle 120 is a horizontal plane, so the reset force direction of the first seal 131 is in the vertical direction. The limiting structure 170 can limit the force of the nozzle cover plate 130 in the vertical direction, thereby limiting the nozzle cover plate 130 from being affected by the reset force of the first seal 131, thereby ensuring that the nozzle cover plate 130 will not shift and ensuring a good seal between the nozzle cover plate 130 and the nozzle 120.

[0083] Specifically, one possible structure of the limiting structure 170 is that the limiting structure 170 includes a limiting groove 171 and a hook 172 that cooperates with the limiting groove 171, and the hook 172 is detachably connected to the limiting groove 171. The limiting groove 171 is located on one of the suction nozzle or the suction nozzle cover, and the hook 172 is located on the other. When installing the suction nozzle cover 130 on the base 110, it is necessary to tilt it at a certain angle so that the hook 172 can enter the limiting groove 171, and then rotate the suction nozzle cover 130 toward the base 110 so that the hook 172 is stuck in the limiting groove 171. At this time, the latch assembly 140 just locks the suction nozzle cover 130 with the base 110. In one embodiment, the hook 172 includes a bent upward portion, such as Figure 2 As shown, when the hook 172 is accommodated in the limiting groove 171, the bent upward portion of the hook 172 is located below the top wall of the limiting groove 171. Thus, the bent upward portion of the hook 172 is limited by the top wall of the limiting groove 171 in the vertical direction, thereby tightly fixing the nozzle cover 130 on the nozzle 120 to ensure sealing.

[0084] It should be noted that since the function of the pre-positioning component 150 is to pre-position the installation position of the nozzle cover 130, and the limiting structure 170 can not only limit the displacement of the nozzle cover 130 in the vertical direction, but also play a role in pre-positioning the installation of the nozzle cover 130, the limiting structure 170 can replace the pre-positioning component 150.

[0085] As an achievable embodiment, please refer to Figure 8 to Figure 11Any one of them, the base assembly 100 also includes a roller brush 160, the base body 110 has a receiving chamber 111 with a bottom end and a front opening, and the nozzle cover plate 130 is located at the front end opening 112 of the receiving chamber 111 to open or block the front end opening 112. The roller brush 160 is located in the receiving chamber 111, and the two ends of the roller brush 160 are rotatably connected to the two side walls of the receiving chamber 111. The bottom opening of the receiving chamber 111 is a roller brush opening 115, and the roller brush 160 abuts against the surface to be cleaned through the roller brush opening 115. The rotation of the roller brush 160 can drive the dust on the surface of the surface to be cleaned to rotate together, which has a dust-raising effect. In addition, the roller brush 160 continuously abuts against the surface to be cleaned during the rolling process, which also has the effect of beating the dust. The raised dust is more likely to enter the suction port 121 along with the adsorption airflow, so the surface to be cleaned can be cleaned more thoroughly.

[0086] During the cleaning process of the surface to be cleaned, dirt will adhere to the roller brush 160 and hair and the like will be entangled with the roller brush 160 as the roller brush 160 rotates, so the roller brush 160 needs to be cleaned regularly. As an achievable embodiment, the roller brush 160 is detachably arranged in the accommodating cavity 111 on the base 110, and the roller brush 160 can be disassembled through the front end opening 112 of the accommodating cavity 111 for easy cleaning. In addition, the upper surface of the suction nozzle 120 is flush with the bottom surface of the accommodating cavity 111, which can avoid affecting the disassembly of the roller brush 160.

[0087] Sometimes, there will inevitably be some solid dirt on the surface to be cleaned. If a vacuum cleaner with only adsorption function is used for cleaning, these solid dirt are difficult to clean. To solve the above problems, please refer to Figure 4 As an achievable embodiment, at least one nozzle 122 is provided on the suction nozzle 120, and a clean water tank for loading clean water is provided on the base body 110 or the device body, and the clean water tank and the nozzle 122 are connected through a pipe 113. The clean water tank is loaded with clean water, and the clean water tank can provide clean water to the nozzle 122 through the pipe 113. When the user encounters solid dirt when cleaning the surface to be cleaned, the nozzle 122 can be operated to spray water to dissolve the solid dirt. In order to accelerate the dissolution of the solid dirt, after the clean water is sprayed on the solid dirt, the cleaning device can be pushed so that the roller brush 160 is located at the solid dirt. The roller brush 160 continuously beats or scrubs the solid dirt to promote the dissolution of the solid dirt, and the solid dirt is formed after dissolution. The sewage can follow the adsorption airflow through the adsorption channel 102 and enter the dirt collection box. Thus, the solid dirt is cleaned.

[0088] When the solid dirt is large, or there is a large area of ​​dirt on the surface to be cleaned, the cleaning efficiency is low if only the nozzle 122 is used to spray water. It is understandable that the nozzle 122 is a point, and the cleaning water sprayed from this point will have a limited range even if it is sprayed in a fan shape. When facing a large area of ​​dirt, the nozzle 122 needs to be operated continuously to spray water, and the amount of water sprayed on the entire solid dirt surface is not uniform, which not only has low efficiency but also affects the subsequent cleaning effect.

[0089] In order to solve the above problem, as an achievable embodiment, please refer to Fig.11 , at least one water spray plate 123 is also provided on the nozzle 122, and the water spray plate 123 is connected to the pipeline 113. It is equivalent to integrating multiple nozzles 122 in an array on a plate. When the cleaning device passes through a large area of ​​solid dirt on the surface to be cleaned, it can spray water on the surface covered by the base assembly 100 and clean it with the roller brush 160 to dissolve the solid dirt and then suck the sewage into the dirt collection box in time, which not only improves the cleaning efficiency but also can control the uniform amount of water sprayed toward the solid dirt, ensuring a uniform and good cleaning effect.

[0090] In order to facilitate the user to control the flow of cleaning water to the nozzle 122 or the water spray plate 123 and make full use of the pipeline, please refer to Figure 8 As an achievable embodiment, the seat body 110 or the equipment body is further provided with a switching valve 114, which is arranged on the pipeline 113 and located on the path through which the clean water flows, and the switching valve 114 can control the clean water to flow to the nozzle 122 or the water spray plate 123. When the clean water tank is located on the seat body 110, the pipeline must be located on the seat body 110, and the switching valve 114 is located in the pipeline on the seat body 110. When the clean water tank is located on the equipment body, the pipeline connecting the clean water tank and the nozzle 122 runs through the equipment body and the seat body 110, then at this time, the switching valve 114 can be arranged on the pipeline located on the equipment body or on the pipeline located on the seat body 110. When the nozzle 122 is needed, the user can control the switching valve 114 to switch to clean water flowing to the nozzle 122, and when the water spray plate 123 is needed, the user can control the switching valve 114 to switch to clean water flowing to the water spray plate 123. As an optional solution, the switching valve 114 is a solenoid valve, which is coupled to a power source device on the equipment body. The equipment body is provided with an operation interface for the user to interact with the cleaning equipment and a controller for controlling the normal operation of the electronic devices on the entire cleaning equipment. The solenoid valve and the operation interface are coupled to the controller, and the user can realize the switching operation of the solenoid valve by operating the corresponding instructions of the operation interface. The controller and the display are conventional settings in this field. The controller commonly used in this field for data calculation and processing and the touch screen display for displaying to the user can be applied to this embodiment.

[0091] In order to expand the application scope of the cleaning device provided in this embodiment, please refer to Fig.11 As an achievable embodiment, the base assembly 100 further includes a roller, which can replace the roller brush 160. A plurality of water sprinkling ports 116 are arranged on the wall of the accommodating cavity 111 parallel to the axis of the roller at intervals along the direction of the axis of the roller. The water sprinkling ports 116 are connected to the clean water tank through a pipeline 113, and a switching valve 114 can switch the clean water to flow to the water sprinkling ports 116. The clean water sprayed from the water sprinkling ports 116 can wet the roller. At this time, the cleaning device is a floor scrubber that can clean the floor surface.

[0092] In order to make the cleaning range of the cleaning device with the above-mentioned floor scrubber function wider, the suction nozzle 120 and the suction nozzle cover 130 can be removed. At this time, the front side of the drum is unobstructed, and the floor at the wall base can be cleaned through the front end of the drum.

[0093] It is understandable that the working principle of the floor scrubber is to use a wet roller to adsorb the dirt on the surface to be cleaned onto the roller. When the roller rotates into the seat 110, a scraper is provided in the seat 110 to abut against the roller to scrape off the sewage attached to the roller. The scraped sewage is adsorbed into the sewage collection box along with the adsorption airflow. Therefore, a scraping strip is provided on the wall of the accommodating chamber 111 of this embodiment to abut against the roller to scrape off the sewage adhered to the roller. It is understandable that since the bristles of the roller brush 160 are made of a flexible material, although the scraping strip will abut against the bristles, it does not affect the rotation of the roller brush 160.

[0094] In order to ensure that the sewage from the cleaning equipment of the above-mentioned floor scrubber function is sucked into the sewage collection tank in time, as an achievable embodiment, please refer to Figure 1The seat body 110 further includes a switching plate 117. A first suction port 118 is provided on the cavity wall of the seat body 110 located above the accommodating cavity 111. A second suction port 119 is provided on the cavity wall of the seat body 110 located away from the front end opening 112 of the accommodating cavity 111. Both the first suction port 118 and the second suction port 119 are connected to the suction mechanism through the adsorption channel 102 located on the seat body 110. The switching plate 117 is arranged in the adsorption channel 102 and is located on the path of the adsorption airflow. The switching plate 117 can move to switch the first suction port 118 to be connected to the suction mechanism or the second suction port 119 to be connected to the suction mechanism. The cover plate channel 101 is connected to the first suction port 118, and the second suction port 119 is located below the scraper, so that the sewage scraped by the scraper can be adsorbed into the sewage collection box through the second suction port 119 in time to ensure the cleaning effect. The switch plate 117 can be shifted according to different modes of the cleaning device to connect the suction mechanism to the cover plate channel 101 or to the second suction port 119. Specifically, when the cleaning device is cleaning the surface of the fabric, the switch plate 117 is switched to connect the suction mechanism to the drive-in cavity, and when the cleaning device is cleaning a plane such as a bottom plate, the switch plate 117 is switched to connect the suction mechanism to the second suction port 119. Preferably, the switch plate 117 is an electromagnetic reversing valve, which is coupled to the power source device and the controller respectively, and the user can operate the reversing function of the electromagnetic reversing valve through the display screen.

[0095] Embodiment 2:

[0096] The present embodiment provides a base assembly base body 110, including a base body 110, a suction nozzle 120 and a suction nozzle cover plate 130. One side of the base body 110 has a accommodating cavity 111 with a front end opening 112. The suction nozzle 120 is arranged on the base body 110, located at the bottom end of the accommodating cavity 111 and abutting against the surface to be cleaned. The suction nozzle 120 has a suction port 121. The suction nozzle cover plate 130 abuts against the suction nozzle 120 and is detachably connected to the base body 110 through at least one latch assembly 140 to block or open the front end opening 112. The accommodating cavity 111 and the suction nozzle cover plate 130 form a starting cavity. The suction port 121 is connected to the bottom end of the starting cavity, and the top end of the starting cavity is connected to the suction mechanism. The nozzle 120 and the nozzle cover 130 are separately arranged so that the disassembly and installation of the nozzle cover 130 and the base 110 do not affect the connection between the nozzle 120 and the base 110, thereby ensuring the reliability of the connection between the nozzle 120 and the base 110. In addition, the nozzle cover 130 and the base 110 can be separated and locked by operating the latch assembly 140 to unlock or lock, which has a simple structure and is convenient for removing the nozzle cover 130 for cleaning and then reinstalling.

[0097] The structure of the base assembly body 110 of this embodiment and the functions of the various components are the same as those of the base assembly 100 on the cleaning device in the first embodiment, and will not be described in detail here.

[0098] Application scenario 1:

[0099] The wool carpet in the living room is full of dust, various debris and a large piece of solid dirt. The user uses the cleaning device provided in the first embodiment to clean the wool carpet.

[0100] First, confirm the mode of the cleaning device. If it is in the scrubber mode, the user switches the scrubber mode to the fabric cleaning mode by touching the display screen. In this mode, the switch plate 117 switches to the cover channel 101 to communicate with the suction mechanism.

[0101] The roller brush 160 is installed in the accommodating cavity 111 instead of the roller. After the suction nozzle 120 is installed on the base 110, the first positioning member 151 on the suction nozzle cover 130 is aligned with the second positioning member 152, and the suction nozzle cover 130 is operated to move so that the first positioning member 151 rotates around the second positioning member 152 or the first positioning member 151 moves along the second positioning member 152. At the same time, the user respectively contacts the handles on both sides of the top of the suction nozzle cover 130 with the index finger and thumb, and applies opposite pinching forces. At this time, the locking pin 141 moves along the reset member 143 toward the suction nozzle cover 130 under the action of the pinching force. When the suction nozzle cover 130 is aligned with the base 110, the user releases the handle. At this time, the locking pin 141 is inserted into the locking port 142 under the action of the reset force of the reset member 143, thereby realizing the installation of the suction nozzle cover 130 and the base 110.

[0102] The user controls the start-up of the cleaning device through the touch display screen and pushes the cleaning device to pass over the surface of the wool carpet. During this process, the head of the suction nozzle 120 contacts the fluff on the wool carpet and causes the fluff to fall in the direction of movement of the head of the suction nozzle 120, thereby exposing the root of the fluff to the suction port 121. The adsorption airflow sucks the dirt, dust or debris at the root of the fluff into the adsorption channel 102, and enters the dirt collecting box through the adsorption channel 102. At the same time, the roller brush 160 located downstream of the suction nozzle 120 beats the fluff on the wool carpet during continuous rotation, and lifts up the dust attached to the fluff. In the process of the user pushing and pulling the cleaning device back and forth, the dust lifted up is sucked into the starting cavity through the suction port 121 and the roller brush port 115, and reaches the dirt collecting box through the adsorption channel 102.

[0103] When cleaning solid dirt on the wool carpet, the user controls the clean water in the clean water tank to flow to the nozzle 122 or the water spray plate 123 through the touch display screen, and the clean water is sprayed onto the solid dirt. In this process, as the user pushes and pulls the cleaning device roller brush 160 back and forth, the solid dirt is continuously scrubbed and patted, so that the solid dirt is dissolved faster. The dissolved sewage follows the adsorption airflow into the suction port 121, and enters the dirt collecting box after passing through the adsorption channel 102.

[0104] Application scenario 2:

[0105] When the user needs to clean the nozzle cover 130 after cleaning, the user controls the demagnetization of the second magnetic part that locks the nozzle cover 130 and the base 110 through the touch display screen. At this time, the nozzle cover 130 and the base 110 are unlocked, and the nozzle cover 130 is moved so that the first positioning part 151 rotates or moves along the second positioning part 152 to separate the nozzle cover 130 from the base 110. At this time, the nozzle cover 130 can be cleaned, and the suction port 121 can be cleaned through the front end opening 112 of the accommodating cavity 111 with a brush or the like. When cleaning is completed, the first positioning member 151 on the nozzle cover 130 is aligned with the second positioning member 152, and the nozzle cover 130 is moved so that the first positioning member 151 rotates around the second positioning member 152 or the first positioning member 151 moves along the second positioning member 152 to align the nozzle cover 130 with the base 110. At this time, the user controls the second magnetic suction member to energize and magnetize through the touch display screen, thereby achieving locking between the nozzle cover 130 and the base 110.
