[0002] With the development of technology, cleaning devices that can improve cleaning efficiency are becoming increasingly diverse. One type of cleaning device cleans by suction, with its suction head connected to the nozzle body via a flexible component, allowing the suction head to rotate relative to the nozzle body. However, during the manufacturing process, the flexible component is difficult to assemble, resulting in low product installation efficiency. Utility Model Content

[0003] In view of this, the present disclosure provides a suction nozzle assembly for a cleaning device to solve the problem of low installation efficiency of flexible components.

[0004] The nozzle assembly of this cleaning device includes a nozzle body, a top cover, a suction head, and a flexible component. The top cover is mounted on the nozzle body to form a suction chamber and a mounting chamber. The suction head is mounted on the nozzle body and has a suction port. The flexible component is mounted within the mounting chamber. The flexible component includes an upper wall and a lower wall. A flexible component channel connects the upper and lower walls, communicating between the suction port and the suction chamber. The nozzle body includes an upper mating portion and a lower mating portion. The upper mating portion mates with the upper wall of the flexible component, and the lower mating portion mates with the lower wall of the flexible component to position the flexible component against the nozzle body. The top cover, mating with the upper wall of the flexible component, presses the flexible component firmly against the nozzle body. A mating portion channel connects the upper and lower mating portions, and the flexible component channel communicates with the suction chamber through this channel.

[0005] Alternatively or supplementarily, the upper mating part is provided with a first positioning part, and the upper wall of the flexible member is provided with a second positioning part. The first positioning part and the second positioning part cooperate to position the upper wall of the flexible member relative to the upper mating part. The top cover is installed on the side of the upper wall of the flexible member away from the upper mating part and presses the upper wall of the flexible member between the top cover and the upper mating part.

[0006] Alternatively or supplementally, the first positioning part is a first positioning protrusion provided on the upper mating part, and the second positioning part is a first positioning hole provided on the upper wall of the flexible member, wherein the first positioning protrusion is at least partially located in the first positioning hole.

[0007] Alternatively or supplementally, the first positioning hole is a through hole that penetrates the upper wall of the flexible member.

[0008] Alternatively, the height of the first positioning protrusion is substantially equal to the thickness of the upper wall of the flexible member.

[0009] Alternatively or supplementally, the first positioning protrusion approaches its top and gradually tilts toward the side where the suction chamber is located.

[0010] Alternatively or supplementally, the nozzle body has a main body bottom wall that partially defines the installation chamber, the flexible lower wall is located between the lower mating part and the main body bottom wall, the flexible lower wall is provided with a second positioning protrusion, the main body bottom wall is provided with a second positioning hole, and the second positioning protrusion is at least partially located in the second positioning hole.

[0011] Alternatively, the bottom wall of the main body is also provided with a guide groove, which extends from the second positioning hole toward the edge of the bottom wall of the main body in the direction away from the suction chamber. The guide groove is configured to guide the second positioning protrusion to slide from the edge into the second positioning hole.

[0012] Alternatively or supplementally, the second positioning protrusion includes an end face and a first guide slope extending from the end face toward the suction chamber, the first guide slope gradually decreasing in the direction toward the suction chamber.

[0013] Alternatively or supplementarily, the upper mating portion and the lower mating portion are arranged opposite to each other in the first direction. The nozzle body also includes two side mating portions opposite to each other in a second direction perpendicular to the first direction.

The fourth positioning protrusion is elastically deformable, moving from the side of the third positioning protrusion away from the suction chamber, through the gap between the third positioning protrusion and the side mating portion, to the side of the third positioning protrusion near the suction chamber. When the fourth positioning protrusion is located on the side of the third positioning protrusion near the suction chamber, the third positioning protrusion abuts against the fourth positioning protrusion to position the flexible member sidewall relative to the main body sidewall.

[0014] Alternatively or supplementarily, the third positioning protrusion and the fourth positioning protrusion are respectively provided with a first abutting surface and a second abutting surface, and the third positioning protrusion is provided with a second guiding slope on the side facing away from the first abutting surface.

[0016] The suction nozzle assembly of the cleaning device provided in this disclosure positions the flexible component by engaging with the upper and lower mating parts of the suction nozzle body with the upper and lower walls of the flexible component, respectively. The top cover then presses the upper wall of the flexible component firmly, facilitating assembly and improving product installation efficiency. Furthermore, by pressing the upper wall of the flexible component firmly with the top cover, movement of the upper and lower walls relative to the upper and lower mating parts is prevented during use of the cleaning device, further enhancing the positioning effect on the flexible component and thus improving product stability.

Detailed Implementation

[0029] Numerous specific details are set forth below to provide an understanding of the structure, function, and use of the embodiments described and illustrated in the specification and figures. It is to be understood that the embodiments described and illustrated herein are non-limiting examples, and thus it will be appreciated that the particular structural and functional details disclosed herein are representative and exemplary. Variations and changes may be made to these embodiments without departing from the scope of the claims.

[0030] A cleaning device can use a fluid (such as water) to clean floors, carpets, sofas, etc. The device includes a supply container, a collection container, a nozzle assembly, tubing, and a water inlet channel. The water inlet channel applies the cleaning fluid from the supply container to the surface of the object being cleaned. The tubing then provides a suction channel, drawing dirt from the surface of the object along with the fluid from the suction head into the collection container, achieving both rapid cleaning and stain collection. While the suction head is typically designed to conform to a level surface for easy cleaning, the nozzle body cannot maintain a fixed angle with the ground during operation. Therefore, the suction head needs to be designed to rotate relative to the nozzle body.

[0031] To design the suction head to rotate relative to the nozzle body while ensuring a continuous suction channel between the nozzle body and the suction head, a flexible component can be installed between the nozzle body and the water brush to connect them. One end of this flexible component connects to the suction head, and the other end connects to the suction chamber of the nozzle body, thus forming a suction channel between the nozzle body and the suction head, allowing the suction head to rotate relative to the nozzle body. To attach the flexible component to the nozzle body, positioning structures that mate with the flexible component can be provided on both the top cover and the nozzle body. The flexible component can only be inserted into the installation space formed by these positioning structures after the top cover is assembled onto the nozzle body. However, during the installation of the cleaning device, the flexible component is difficult to insert into the installation space, making assembly challenging.

[0032] Therefore, to facilitate the assembly of flexible components and improve product installation efficiency, this disclosure improves the nozzle assembly of the cleaning device. The nozzle assembly of the cleaning device according to this disclosure is illustrated below with reference to the accompanying drawings.

[0033] like Figures 1 to 5 As shown, one embodiment of this disclosure provides a suction nozzle assembly 100 for a cleaning device. The suction nozzle assembly 100 includes a suction nozzle body 10, a top cover 20, a suction head 30, and a flexible member 40. The top cover 20 is mounted on the suction nozzle body 10 to cooperate with the suction nozzle body 10 to form a suction chamber 50 and a mounting chamber 60. The mounting chamber 60 provides mounting space for parts that need to be mounted on the suction nozzle body 10. The suction head 30 is mounted on the suction nozzle body 10 and has a suction port 31. After cleaning the object, dirty fluid containing stains can also be sucked in through the suction port 31. The flexible member 40 is installed within the mounting chamber 60. The flexible member 40 includes an upper flexible member wall 41 and a lower flexible member wall 42. A flexible member channel 43 communicating between the upper flexible member wall 41 and the lower flexible member wall 42 and the suction port 31 and the suction chamber 50 is provided. When the suction head 30 rotates relative to the nozzle body 10, the upper wall 41 and the lower wall 42 of the flexible component can both undergo elastic deformation, thereby maintaining the connection of the suction channel from the suction port 31 through the flexible component channel 43 to the suction chamber 50, and maintaining a sealed connection with the suction head 30 and the suction chamber 50.

[0034] The nozzle body 10 includes an upper mating portion 11 and a lower mating portion 12. The upper mating portion 11 mates with the upper wall 41 of the flexible component, and the lower mating portion 12 mates with the lower wall 42 of the flexible component to position the flexible component 40 to the nozzle body 10. The top cover 20 mates with the upper wall 41 of the flexible component to press the flexible component 40 to the nozzle body 10. A mating channel 13 is provided between the upper mating portion 11 and the lower mating portion 12, and the flexible component channel 43 communicates with the suction chamber 50 through the mating channel 13.

[0035] The suction nozzle assembly 100 of the cleaning device provided in this embodiment positions the flexible component 40 by engaging the upper mating portion 11 and the lower mating portion 12 of the suction nozzle body 10 with the upper wall 41 and the lower wall 42 of the flexible component, respectively. The upper wall 41 of the flexible component is then pressed down by the top cover 20, making the flexible component 40 easy to assemble and thus improving the installation efficiency of the product. In addition, by pressing down the upper wall 41 of the flexible component with the top cover 20, the upper wall 41 and the lower wall 42 of the flexible component can be prevented from moving relative to the upper mating portion 11 and the lower mating portion 12 during the use of the cleaning device, further enhancing the positioning effect on the flexible component 40 and thus improving the stability of the product.

[0036] In some embodiments, such as Figures 3 to 5 As shown, the specific way in which the upper mating part 11 and the upper wall 41 of the flexible member cooperate is as follows: the upper mating part 11 is provided with a first positioning part 111, and the upper wall 41 of the flexible member is provided with a second positioning part 411. The first positioning part 111 and the second positioning part 411 cooperate to position the upper wall 41 of the flexible member relative to the upper mating part 11.

[0037] The top cover 20 presses the upper wall 41 of the flexible component in the following way: the top cover 20 is installed on the side of the upper wall 41 of the flexible component away from the upper mating part 11, and presses the upper wall 41 of the flexible component between the top cover 20 and the upper mating part 11.

[0038] In some embodiments, such as Figures 3 to 5 As shown, the first positioning part 111 is a first positioning protrusion 111 provided on the upper mating part 11, and the second positioning part 411 is a first positioning hole 411 provided on the upper wall 41 of the flexible member. The first positioning protrusion 111 is at least partially located in the first positioning hole 411. When the suction head 30 rotates relative to the nozzle body 10, the upper wall 41 of the flexible member will tend to move relative to the upper mating part 11 due to tension or compression. Since the first positioning protrusion 111 is in the first positioning hole 411, the sidewall of the first positioning protrusion 111 will abut against the sidewall of the first positioning hole 411 to prevent the upper wall 41 of the flexible member from moving relative to the upper mating part 11, thus preventing the upper wall 41 of the flexible member from falling off the upper mating part 11 when the suction head 30 rotates relative to the nozzle body 10, thereby improving the stability of the product. For example, the upper mating part 11 may be provided with 5 first positioning protrusions 111, and the upper wall 41 of the flexible member may be provided with 5 first positioning holes 411 accordingly. It should be noted that the number of the first positioning protrusion 111 and the first positioning hole 411 is not limited to this, and can be set according to actual needs.

[0039] In other embodiments, the first positioning part 111 may also be a positioning hole provided on the upper mating part 11, and the second positioning part 411 may also be a positioning protrusion provided on the upper wall 41 of the flexible member. The positioning protrusion of the upper wall 41 of the flexible member may also be located at least partially in the positioning hole on the upper mating part 11, so as to realize the positioning function of the upper mating part 11 on the upper wall 41 of the flexible member.

[0040] The first positioning hole 411 can be a through hole or a blind hole. A blind hole refers to the first positioning hole 411 not extending through the thickness of the upper wall 41 of the flexible member, but only extending a portion of the thickness from one side surface of the upper wall 41 to the other side surface, thus forming a groove. In some embodiments, such as... Figure 4 As shown, the first positioning hole 411 is a through hole that passes through the upper wall 41 of the flexible component. When the flexible component 40 is installed onto the nozzle body 10, the first positioning hole 411 and the first positioning protrusion 111 can be observed through the through hole to see whether they are installed in place, which helps to improve the installation efficiency of the product.

[0041] If the height of the first positioning protrusion 111 is too high compared to the thickness of the upper wall 41 of the flexible member, it will result in an excessively large gap between the first positioning protrusion 111 and the top cover 20. The upper wall 41 of the flexible member will easily detach through this gap after being stretched and deformed. Therefore, in some embodiments, such as... Figure 5 As shown, the height of the first positioning protrusion 111 is basically equal to the thickness of the upper wall 41 of the flexible component, so as to avoid the problem that the upper wall 41 of the flexible component will detach through the gap after deformation due to the excessive gap between the first positioning protrusion 111 and the top cover 20.

[0042] In some embodiments, such as Figure 5 As shown, the first positioning protrusion 111 gradually tilts towards the side where the suction chamber 50 is located as it approaches its top, that is, towards... Figure 5 The first positioning protrusion 111 is inclined in the S1 direction. When the upper wall 41 of the flexible component is subjected to a pulling force away from the suction chamber 50 (S2 direction), the first positioning protrusion 111 will hook onto the upper wall 41 of the flexible component. Specifically, the inclined first positioning protrusion 111 can abut against the first positioning hole 411 both in the S1 direction and in the direction towards the upper mating part 11, thereby preventing the upper wall 41 of the flexible component from moving in the S2 direction and also preventing the upper wall 41 of the flexible component from moving away from the upper mating part 11. Therefore, the first positioning protrusion 111 gradually tilts towards the side where the suction chamber 50 is located as it approaches its top, which can further improve the stability of the product.

[0043] In some embodiments, such as Figure 3 , Figure 4 and Figure 5As shown, the nozzle body 10 has a main body bottom wall 14 that partially defines the mounting chamber 60. A flexible lower wall 42 is located between the lower mating portion 12 and the main body bottom wall 14. The flexible lower wall 42 is provided with a second positioning protrusion 421, and the main body bottom wall 14 is provided with a second positioning hole 141. The second positioning protrusion 421 is at least partially located in the second positioning hole 141. After the second positioning protrusion 421 is at least partially located in the second positioning hole 141, when the flexible lower wall 42 tends to move relative to the lower mating portion 12, the sidewall of the second positioning hole 141 will resist the sidewall of the second positioning protrusion 421, thereby restricting the movement of the flexible lower wall 42 relative to the lower mating portion 12.

[0044] In some embodiments, such as Figure 3 , Figure 5 and Figure 6 As shown, the main body bottom wall 14 is also provided with a guide groove 142. The guide groove 142 extends from the second positioning hole 141 in the direction away from the suction chamber 50 (S2 direction) to the edge of the main body bottom wall 14. The guide groove 142 is configured to guide the second positioning protrusion 421 to slide from the edge into the second positioning hole 141. By providing the guide groove 142, when the flexible member 40 is installed, the second positioning protrusion 421 can slide along the guide groove 142 from the edge of the main body bottom wall 14 into the second positioning hole 141. Specifically, when the second positioning protrusion 421 is located at the edge of the main body bottom wall 14, the two side walls of the guide groove 142 can respectively abut against the second positioning protrusion 421 on both sides of the second positioning protrusion 421. The second positioning protrusion 421 can only move along the extension direction of the guide groove 142, that is, in the S1 direction. When the second positioning protrusion 421 slides along the guide groove 142 to the second positioning hole 141, the side wall of the second positioning hole 141 will abut against the side wall of the second positioning protrusion 421, at which point the second positioning protrusion 421 can be installed in place. Therefore, providing the guide groove 142 on the bottom wall 14 of the main body can improve the installation efficiency of the product.

[0045] In some embodiments, such as Figure 4 , Figure 5 and Figure 6As shown, the second positioning protrusion 421 includes an end face 4211 and a first guide slope 4212 extending from the end face 4211 toward the suction chamber 50 (S1 direction). The first guide slope 4212 gradually slopes toward the bottom of the second positioning protrusion 421 along the direction toward the suction chamber 50, so as to gradually approach the surface of the lower wall 42 of the flexible member along the direction toward the suction chamber 50. When installing the flexible member 40, the side of the second positioning protrusion 421 approaching the suction chamber 50 first contacts the edge of the main body bottom wall 14. Since the height of the side of the second positioning protrusion 421 approaching the suction chamber 50 is lower than the height of the side away from the suction chamber 50, it is easier to enter the gap between the lower mating part 12 and the main body bottom wall 14. When the lower wall 42 of the flexible member moves toward the S1 direction, the first guide slope 4212 will at least partially fit against the main body bottom wall 14 after being squeezed and deformed, thereby facilitating the sliding of the lower wall 42 of the flexible member into place. After the lower wall 42 of the flexible component is installed in place, the second positioning protrusion 421 is at least partially located in the second positioning hole 141. At this time, the end face 4211 of the second positioning protrusion 421 can abut against the side wall of the second positioning hole 141, thereby preventing the lower wall 42 of the flexible component from moving relative to the lower mating part 12. Therefore, by providing the first guide slope 4212 on the second positioning protrusion 421, not only can the installation efficiency of the product be improved, but also the stability of the product can be improved.

[0046] It should be noted that the end face 4211 of the second positioning protrusion 421 is not necessary. In some embodiments, the second positioning protrusion 421 does not include the end face 4211. The first guide slope 4212, which gradually decreases in the direction approaching the suction chamber 50, can also facilitate the sliding of the lower wall 42 of the flexible component into place and position it after it has slid into place, thereby improving the product installation efficiency and stability.

[0047] In some embodiments, such as Figure 3 , Figure 4 and Figure 7As shown, the upper mating portion 11 and the lower mating portion 12 are arranged opposite to each other in a first direction. The first direction includes the X1 direction and the X2 direction, which are opposite to each other. The upper mating portion 11 and the lower mating portion 12 are located on the X1 direction side and the X2 direction side, respectively, in the first direction. The nozzle body 10 also includes two side mating portions 15 that are opposite to each other in a second direction perpendicular to the first direction. The second direction includes the Y1 direction and the Y2 direction, which are opposite to each other. The two side mating portions 15 are located on the Y1 direction side and the Y2 direction side, respectively, in the second direction. The mating portion channel 13 is located between the two side mating portions 15 in the second direction. The nozzle body 10 also includes two main body sidewalls 16, which are located outside the two side mating portions 15 in the second direction. The flexible member 40 also includes two flexible member sidewalls 44, each flexible member sidewall 44 being located between a corresponding side mating portion 15 and a corresponding main body sidewall 16. The main body sidewall 16 is provided with a third positioning protrusion 161 protruding toward the flexible member sidewall 44. The flexible sidewall 44 is provided with a fourth positioning protrusion 441 protruding towards the main body sidewall 16. The fourth positioning protrusion 441 can elastically deform from the S2 direction side of the third positioning protrusion 161, passing through the gap between the third positioning protrusion 161 and the side mating part 15, to the S1 direction side of the third positioning protrusion 161. When the fourth positioning protrusion 441 is located on the S1 direction side of the third positioning protrusion 161, the third positioning protrusion 161 abuts against the fourth positioning protrusion 441 to position the flexible sidewall 44 relative to the main body sidewall 16. When the flexible sidewall 44 is subjected to a tensile force along the S2 direction, the abutment between the third positioning protrusion 161 and the fourth positioning protrusion 441 positions the flexible sidewall 44 relative to the main body sidewall 16, preventing the flexible sidewall 44 from moving relative to the main body sidewall 16 along the S2 direction, thereby preventing the flexible sidewall 44 from detaching during the use of the cleaning device. By positioning the upper wall 41, lower wall 42, and two side walls 44 of the flexible component, the movement of the flexible component 40 can be restricted in all directions, thereby further improving the stability of the product.

[0048] In some embodiments, the third positioning protrusion 161 and the fourth positioning protrusion 441 are respectively provided with a first abutting surface 1611 and a second abutting surface 4411 that abut against each other. The third positioning protrusion 161 is provided with a second guiding slope 1612 on the side opposite to the first abutting surface 1611. The second guiding slope 1612 approaches the top of the third positioning protrusion 161 and gradually slopes toward the first abutting surface 1611. Figure 7 It shows Figure 3The third positioning protrusion 161 and the corresponding fourth positioning protrusion 441 are located on the X1 direction side. The top of the third positioning protrusion 161 is the end of the third positioning protrusion 161 closest to the suction chamber 50, that is, the third positioning protrusion 161 gradually protrudes away from the main body sidewall 16 along the S1 direction. When installing the flexible component 40, the fourth positioning protrusion 441 first contacts the end of the second guide slope 1612 away from the suction chamber 50. As the flexible component sidewall 44 moves in the S1 direction, the fourth positioning protrusion 441 will abut against the second guide slope 1612, causing the flexible component sidewall 44 to gradually deform in the X2 direction. When the second abutment surface 4411 moves in the S1 direction beyond the position of the first abutment surface 1611, the fourth positioning protrusion 441 will move in the X1 direction under the action of the elastic restoring force of the flexible component sidewall 44, causing the first abutment surface 1611 and the second abutment surface 4411 to abut against each other, at which point the flexible component sidewall 44 is installed in place. When the flexible sidewall 44 tends to move along the S2 direction, the first abutment surface 1611 will resist the second abutment surface 4411, preventing the flexible sidewall 44 from moving along the S2 direction, thereby preventing the flexible sidewall 44 from falling off during the use of the cleaning device. Therefore, by providing the second guide slope 1612 on the third positioning protrusion 161, the installation efficiency of the product is improved; by providing the first abutment surface 1611 on the third positioning protrusion 161 to resist the second abutment surface 4411 of the fourth positioning protrusion 441, the stability of the product is improved.

[0049] This disclosure also provides a cleaning device 1000, including the aforementioned nozzle assembly 100, device body 200, and tube 300. For example... Figure 8 As shown, one end of the tube 300 is connected to the nozzle assembly 100, and the other end is connected to the device body 200, creating a suction flow path from the suction port 31 of the nozzle assembly 100 to the interior of the device body 200 when the suction source is running. The cleaning device 1000 can be, for example, a floor scrubber, used to clean floors, carpets, and sofas. The device body 200 may include a supply container and a recovery container. When the suction source is running, the cleaning fluid in the supply container is applied to the surface of the object being cleaned through the water injection channel. After the surface of the object being cleaned is washed by the cleaning fluid, the dirty fluid carrying stains can be sucked in at the suction port 31 of the nozzle assembly 100, and then sequentially drawn into the recovery container through the flexible channel 43, the suction chamber 50, and the tube 300.

[0050] It should be noted that the elements described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0051] It should be understood that multiple components and / or parts can be provided by a single integrated component or part. Alternatively, a single integrated component or part can be divided into multiple separate components and / or parts.
