Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning base station design, and particularly relates to a cleaning base station and an infusion tube. Background Art

[0002] With the improvement of people's living standards, household intelligent devices are becoming more and more common in people's lives. Among them, cleaning robots are a relatively common type of household intelligent device, which can replace users to clean indoors and ensure the living environment.

[0003] The cleaning robots related to the related technology need to be configured with a cleaning base station. The cleaning base station has a position for the cleaning robot to dock. The cleaning robot docks in the cleaning base station to perform operations such as cleaning and drying the mop. Correspondingly, the cleaning base station is equipped with a retractable infusion tube, such as a sewage pipe and a water purification pipe. The infusion tube needs to be retractable during operation. Taking the sewage pipe as an example, after the cleaning robot finishes cleaning the mop, the sewage pipe needs to extend to the sewage pool to pump out the sewage. After pumping out the sewage, the sewage pipe needs to retract and then withdraw from the sewage pool.

[0004] In the related technology, the sewage pipe configured in the cleaning base station uses a corrugated pipe. Although the corrugated pipe can achieve retraction, the corrugated pipe has a problem of poor liquid passing ability, which is not conducive to the rapid drainage of sewage from the sewage pipe. Of course, not limited to the sewage pipe, other types of infusion tubes also have the problem of weak liquid passing ability when using corrugated pipes. Summary of the Utility Model

[0005] The utility model discloses a cleaning base station and an infusion tube to solve the problem of weak liquid passing ability caused by using corrugated pipes for the infusion tubes related to the related technology.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] In a first aspect, an embodiment of the utility model discloses an infusion tube. The infusion tube is a flexible tube, and the infusion tube includes a plurality of sequentially connected pipe segments. The inner wall of each pipe segment is provided with a spiral groove extending along the extension direction of the pipe segment, and the spiral directions of the spiral grooves on two adjacent pipe segments are opposite.

[0008] In a second aspect, an embodiment of the utility model discloses a cleaning base station, and the disclosed cleaning base station includes the infusion tube described in the first aspect.

[0009] The technical solutions adopted by the utility model can achieve the following technical effects:

[0010] The infusion tube disclosed in the embodiment of the present utility model improves the structure of using a corrugated tube as the infusion tube in the related art. A spiral groove extending along the extension direction of the tube section is provided on the inner wall of the tube section included in the flexible tube, so that while the flexible tube has good telescopic performance, due to the spiral groove extending along the extension direction of the tube section, the tube section has good liquid passing ability. At the same time, among the multiple tube sections included in the infusion tube disclosed in the embodiment of the present utility model, the spiral directions of the spiral grooves in two adjacent tube sections are opposite, so that the liquid guided by the spiral groove will not continuously accumulate spiral and be subjected to excessive centrifugal force when flowing through the infusion tube, thereby avoiding the influence of excessive centrifugal force on the water passing through, which can further improve the liquid passing ability of the water delivery pipe. It can be seen that the infusion tube disclosed in the embodiment of the present utility model can better improve the liquid passing ability, thereby better solving the problem of weak liquid passing ability existing in using a corrugated tube as the infusion tube in the related art.

[0011] In addition, the inventor unexpectedly found that among the multiple tube sections included in the infusion tube disclosed in the embodiment of the present utility model, since the spiral directions of the spiral grooves in two adjacent tube sections are opposite, when one end of the infusion tube moves relative to the other end for telescoping, the slight rotation of the infusion tube caused by the spiral of the spiral grooves in two adjacent tube sections will cancel each other out, thereby avoiding the transfer of torsional force to both ends of the infusion tube and causing connection reliability problems at both ends of the infusion tube.

[0018] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0019] The technical solutions disclosed in each embodiment of the present utility model will be described in detail below with reference to the drawings.

[0020] Please refer to Figures 1 to 3 , an infusion tube 10 is disclosed in an embodiment of the present utility model. The infusion tube 10 is a tubular structural member that can be telescoped. The infusion tube 10 is a flexible tube, and thus can be telescoped by flexible deformation. The infusion tube 10 disclosed in the embodiment of the present utility model can be used in the cleaning base station described in the background art, and can also be used as a telescopic infusion pipeline in other types of equipment. The embodiment of the present utility model does not make any restrictions.

[0021] The infusion tube 10 disclosed in the embodiment of the present utility model includes a plurality of sequentially connected pipe segments 11. The plurality of pipe segments 11 are sequentially connected along the through direction of the infusion tube 10 to form a through infusion structure. Two adjacent pipe segments 11 can be of an integral structure, or can be connected by means of bonding, welding, etc. The embodiment of the present utility model does not limit the specific connection manner of the plurality of pipe segments 11.

[0022] Among the plurality of pipe segments 11, a spiral groove 101 extending along the extension direction of the pipe segment 11 is provided on the inner wall of each pipe segment 11. Specifically, the spiral groove 101 on the inner wall of each pipe segment 11 spirally extends along the through direction of the pipe segment 11, so as to extend from one end of the pipe segment 11 to the other end. The provision of the spiral groove 101 on the inner wall of each pipe segment 11 enables the infusion tube 10, which is essentially a flexible tube, to have good telescopic performance, so that it can be telescopically extended well during the working process.

[0023] At the same time, the spiral groove 101 spirally extends from one end of the pipe segment 11 to the other end. Therefore, the spiral groove 101 can guide the liquid being transported to pass through the infusion tube 10 more easily during the infusion process of the infusion tube 10, which is beneficial to improving the liquid passing capacity of the infusion tube 10. Since the inner wall of the corrugated pipe is an annular groove, the resistance to the liquid is relatively large. Therefore, compared with the corrugated pipe used in the related art, the infusion tube 10 disclosed in the embodiment of the present utility model has a stronger liquid passing capacity.

[0024] In the embodiment of the present utility model, the spiral directions of the spiral grooves 101 on two adjacent pipe segments 11 are opposite, so that when the liquid flows through one pipe segment 11 and then into an adjacent another pipe segment 11, it can be reversely guided to reduce the centrifugal force received by the liquid, which is beneficial for the liquid to better extend along the through direction of the pipe segment 11, and this can further improve the liquid passing capacity of the infusion tube 10. In the embodiment where the infusion tube 10 is used as a sewage discharge pipe, since the centrifugal force received by the sewage can be reduced, the bad adhesion caused by the dirt in the sewage being thrown onto the inner wall of the pipe segment 11 due to a large centrifugal force can also be reduced.

[0025] The infusion tube 10 disclosed in the embodiment of the present utility model improves the structure of using a corrugated pipe as the infusion tube 10 in the related art. A spiral groove 101 extending along the extension direction of the pipe segment 11 is provided on the inner wall of the pipe segment 11 included in the flexible pipe, so that while the flexible pipe has good telescopic performance, because the spiral groove 101 extends along the extension direction of the pipe segment 11, the pipe segment 11 has good liquid passing capacity. At the same time, among the multiple pipe segments 11 included in the infusion tube 10 disclosed in the embodiment of the present utility model, the spiral directions of the spiral grooves 101 in two adjacent pipe segments 11 are opposite, so that the liquid guided by the spiral groove 101 will not continuously accumulate spiral and receive too large centrifugal force when flowing through the infusion tube 10, thus avoiding the influence on passing due to the liquid receiving too large centrifugal force, and at the same time, it is also easy for the liquid to form a turbulent flow, which can further improve the liquid passing capacity of the infusion tube 10. It can be seen that the infusion tube 10 disclosed in the embodiment of the present utility model can better improve the liquid passing capacity, and thus can better solve the problem of weak liquid passing capacity existing in using a corrugated pipe as the infusion tube in the related art.

[0026] In addition, the inventor unexpectedly found that among the multiple pipe segments 11 included in the infusion tube 10 disclosed in the embodiment of the present utility model, since the spiral directions of the spiral grooves 101 in two adjacent pipe segments 11 are opposite, when one end of the infusion tube 10 moves relative to the other end for telescoping, the slight rotation of the infusion tube 10 caused by the spiral of the spiral groove 101 in two adjacent pipe segments 11 will cancel each other out, thus avoiding the connection reliability problem at both ends of the infusion tube 10 caused by the torsional force being transmitted to both ends of the infusion tube 10.

[0027] In the embodiment where the infusion tube 10 disclosed in the embodiment of the present utility model is applied to a cleaning base station, since the infusion tube 10 can take into account improving the liquid passing capacity and the connection stability, the cleaning base station using the infusion tube 10 disclosed in the embodiment of the present utility model has the advantage of reliable infusion. Of course, the infusion in this process can be the process of discharging sewage or the process of inputting clean water, and the embodiment of the present utility model does not make a limitation.

[0028] In the embodiments of the present utility model, one spiral groove 101 may be provided on the inner wall of each pipe section 11, or multiple spiral grooves 101 may be provided. The embodiments of the present utility model do not limit the number of spiral grooves 101 formed on the inner wall of each pipe section 11. In a more preferred solution, multiple spiral grooves 101 may be provided on the inner wall of each pipe section 11 in order to better balance the flexibility of the pipe section 11 for convenient telescoping while also improving the liquid passing capacity of the pipe section 11. The multiple spiral grooves 101 in each pipe section 11 extend from one end of the pipe section 11 to the other end. In this case, on the basis of ensuring the telescoping of the infusion tube 10, the multiple spiral grooves 101 can not only guide the liquid simultaneously to improve the liquid passing capacity, but also avoid the problem of insufficient strength of the infusion tube 10 caused by too few spiral grooves 101, thereby making the infusion tube 10 not easily collapse.

[0029] The multiple spiral grooves 101 provided on the inner wall of each pipe section 11 do not intersect on the pipe section 11. In a specific embodiment, the multiple spiral grooves 101 provided on the inner wall of each pipe section 11 may be substantially parallel. Specifically, the multiple spiral grooves 101 provided on the inner wall of each pipe section 11 may be parallel.

[0030] In the embodiments where multiple spiral grooves 101 are provided on the inner wall of the pipe section 11, the depths of the spiral grooves 101 in each pipe section 11 may be equal or unequal, and the embodiments of the present utility model do not make any restrictions. In an alternative solution, in order to make the liquid more likely to form turbulence when passing through, among the multiple spiral grooves 101 provided in each pipe section 11, the depth of the spiral groove 101, the cross-sectional shape of the spiral groove 101, and the width of the groove opening of the spiral groove 101 may be different. For the convenience of manufacturing, the shapes and various dimensional parameters of the multiple spiral grooves 101 provided on the inner wall of each pipe section 11 may also be exactly the same. The embodiments of the present utility model do not impose excessive restrictions.

[0031] In order to further improve the strength of the infusion tube 10 and prevent it from collapsing, in one embodiment, a spiral reinforcing protrusion 12 may be provided on the outer wall of each pipe section 11, and the spiral reinforcing protrusion 12 may be arranged around the corresponding pipe section 11. The spiral reinforcing protrusion 12 can improve the strength of the pipe section 11. More specifically, the spiral reinforcing protrusion 12 may extend from one end of the corresponding pipe section 11 to the other end along the extending direction of the corresponding pipe section 11, so as to achieve a better strengthening effect.

[0032] The embodiments of the present utility model do not limit the specific setting position of the spiral reinforcing protrusion 12. Considering that the inner wall of each pipe section 11 is provided with a spiral groove 101, in an alternative embodiment, on each pipe section 11, the spiral reinforcing protrusion 12 can be in one-to-one correspondence with the spiral groove 101, and the spiral reinforcing protrusion 12 is provided on the outer side of the bottom wall of the opposite spiral groove 101. That is to say, the spiral groove 101 and the spiral reinforcing protrusion 12 are respectively located on the inner and outer sides of the same part of the pipe section 11. This structure enables the spiral reinforcing protrusion 12 to be distributed along the spiral groove 101, thereby facilitating the setting of the spiral reinforcing protrusion 12. In an embodiment where the infusion tube 10 is integrally injection-molded, the inner and outer sides of the corresponding part of the pipe section 11 can be made to be sunken and convex respectively through mold design to form the spiral groove 101 and the spiral reinforcing protrusion 12, thereby facilitating the synchronous molding of these two structures and being beneficial to improving the manufacturing efficiency of the infusion tube 10.

[0033] To further improve the strength of the infusion tube 10, the infusion tube 10 disclosed in the embodiments of the present utility model may further include an annular reinforcing protrusion 13. An annular reinforcing protrusion 13 may be provided at the connection of two adjacent pipe sections 11. The annular reinforcing protrusion 13 can enhance the radial strength of the infusion tube 10, so that the infusion tube 10 is less likely to collapse. To avoid affecting the liquid passage, the annular reinforcing protrusion 13 is provided on the outer wall at the connection of two adjacent pipe sections 11.

[0034] The infusion tube 10 may only include a plurality of sequentially connected pipe sections 11. In this case, among the plurality of pipe sections 11, the two pipe sections 11 located at both ends of the infusion tube 10 are used to connect with other components (such as the fixing member 20 and the driving mechanism 30 described later), so as to realize the installation of the infusion tube 10. In other embodiments, the infusion tube 10 may include a first connection section 14, a second connection section 15, and a tube body. The tube body includes the plurality of sequentially connected pipe sections 11 mentioned above. The first connection section 14 is connected to the pipe section 11 at one end of the tube body. The second connection section 15 is connected to the pipe section 11 at the other end of the tube body. The infusion tube 10 with this structure is specifically provided with the first connection section 14 and the second connection section 15, so as to facilitate the connection of the infusion tube 10 with other components of the corresponding equipment (such as a cleaning base station), thus facilitating the installation.

[0035] The structures of the first connection section 14 and the second connection section 15 can be various. The embodiments of the present utility model do not limit the specific structures of the first connection section 14 and the second connection section 15. In one embodiment, at least one of the first connection section 14 and the second connection section 15 may be a threaded connection section, and thus connection with the other components described above is achieved through threaded cooperation. In another embodiment, the first connection section 14 and the second connection section 15 may be snap connection sections including snaps, and thus connection with the other components described above is achieved through snap connection.

[0036] In yet another embodiment, both the first connecting section 14 and the second connecting section 15 can be straight pipe sections. The first connecting section 14 and the second connecting section 15 can be communicated through the pipe body. The first connecting section 14 and the second connecting section 15 can be respectively fixedly connected to other components described above through a clamping mechanism (such as a hoop).

[0037] In the embodiment of the present utility model, the infusion tube 10 can be of an integral structure or a split structure, and the embodiment of the present utility model does not limit this. For the convenience of manufacturing, the infusion tube 10 can adopt an integral structure. For example, the infusion tube 10 is formed by an integral injection molding process.

[0038] As described above, the infusion tube 10 is a flexible tube and is made of a flexible material. For example, the infusion tube 10 can be a silicone tube made of silicone material. Again, for example, the infusion tube 10 can be a rubber tube made of rubber material. Of course, the embodiment of the present utility model does not limit the specific material of the infusion tube 10.

[0039] Based on the infusion tube 10 disclosed in the embodiment of the present utility model, please refer to Figure 3 , the embodiment of the present utility model further discloses a cleaning base station. The disclosed cleaning base station can include the infusion tube 10 described in any one of the above embodiments. The infusion tube 10 can be used as the sewage pipe of the cleaning base station, can also be used as the clean water pipe of the cleaning base station, and can also be used as other pipelines of the cleaning base station. The embodiment of the present utility model does not limit this.

[0040] In one embodiment, the cleaning base station can include a fixing member 20 and a driving mechanism 30. The fixing member 20 is a structural member that fixes the first end of the infusion tube 10 to the housing of the cleaning base station. The driving mechanism 30 is disposed inside the housing of the cleaning base station. The driving mechanism 30 can be a linear motor, a link driving mechanism, a hydraulic telescopic member, a pneumatic telescopic member, etc. The embodiment of the present utility model does not limit the specific type of the driving mechanism 30. The driving mechanism 30 is connected to the second end of the infusion tube 10, and the driving mechanism 30 can drive the second end of the infusion tube 10 to move relative to the first end of the infusion tube 10, so as to realize the telescopic movement of the infusion tube 10.

[0041] In the above embodiments of the present utility model, the differences between the various embodiments are mainly described. As long as the different optimized features of the various embodiments are not contradictory, they can be combined to form a more optimal embodiment. Considering the simplicity of the text, it will not be elaborated here.

[0042] The embodiments of the present utility model have been described above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present utility model, those of ordinary skill in the art can also make many forms without departing from the spirit of the present utility model and the scope protected by the claims, and all of them fall within the protection scope of the present utility model.
