Description

Technical Field

[0001] This disclosure relates to the field of cleaning tool technology, and more specifically, to a cleaning handle that is easy to operate. Background Technology

[0002] The spray and suction cleaner can directly clean fabric surfaces without disassembly, just like hand washing clothes. It has a long lifespan, does not damage materials, and solves the problems of inefficiency and cumbersome disassembly in traditional cleaning methods. The cleaner sprays and suctions immediately without leaving any residue, and there is no dripping or leakage. It is widely used in the cleaning of fabric sofas, curtains and carpets. In addition, there is no need for special drying after cleaning, which reduces the impact of cleaning on daily life.

[0003] Existing cleaning device handles have relatively simple structures. For example, patent CN202321491326.X describes a multi-functional cleaning nozzle and a cleaning machine equipped with the nozzle, and patent CN202121279373.9 describes a spray-suction cleaning device. These devices use a rigid suction tube as a handle for hand operation, while the water supply tube is separate from the suction tube. Since high-temperature cleaning is often required during the cleaning process, the high temperature of the water supply tube can easily burn the operator's hand or arm, resulting in insufficient convenience and safety. Another example is patent CN202420592832.6, which describes a suction nozzle and household suction device with an ergonomic design. A hand handle is formed by extending the suction tube to the end, which can avoid burns to some extent. However, the hand handle of this structure is not ergonomically designed. Since the cleaning part, water supply tube, and suction tube are all located at the front of the hand handle, the handle and tubes have a certain weight due to the lever principle, increasing the force on the hand and hindering the flexibility of hand operation.

[0004] Therefore, this design proposes a convenient cleaning handle that can effectively prevent scalding and improve the flexibility of manual operation.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this disclosure is to provide a cleaning handle that is easy to operate, thereby overcoming, at least to some extent, one or more problems caused by the limitations and defects of the related technology.

[0007] According to one aspect of this disclosure, a conveniently operable cleaning handle is provided, comprising a water inlet tube, a suction tube, a cleaning nozzle, and a handheld body; wherein,

[0008] The handheld body is formed by two half-shells fastening together to form its handheld shell, which includes a handheld part, a curved neck and a connecting part. There is an operating angle between the connecting part and the handheld part. The two are connected by the rounded corner of the curved neck. The operating angle is 120°≤140°. The handheld shell is provided with a positioning and guiding positioning structure for the water supply pipe and the water suction pipe.

[0009] The cleaning nozzle is mounted on the connecting part at the front end of the handheld body and extends forward along the axis of the connecting part. The cleaning nozzle includes a nozzle body and a nozzle. The nozzle body is a hollow, flat structure. The nozzle is located inside the nozzle body, and its threaded connector extends out from below the nozzle body. The cleaning surface at the front end of the nozzle body is sloping to form a slope angle with the vertical cleaning plane, with a slope angle of 15° ≤ 20°.

[0010] The water supply pipe includes an external connecting pipe, a control valve pipe, an internal water supply branch pipe, and a flexible water supply pipe. One end of the internal water supply branch pipe is connected to the control valve pipe, and the other end is connected to the flexible water supply pipe.

One end of the internal suction branch tube is connected to the inner end of the connector tube, and the other end is connected to the flexible suction tube.

[0012] In one exemplary embodiment of this disclosure, a switch seat is integrally formed on the upper part of the handle or at the connection between the handle and the bend neck. The switch seat protrudes from the circumferential surface of the handle, and a control switch is provided on its right side. The control switch is connected to a control valve pipe for controlling the on / off state of the water supply pipe.

[0013] In one exemplary embodiment of this disclosure, the handheld part has a cam-shaped circular structure, with its lower half-arc covering the outside of the built-in water supply branch pipe and its upper half-arc covering the outside of the built-in water absorption branch pipe. An anti-slip structure is provided on the outer peripheral surface of the lower half-arc.

[0014] In one exemplary embodiment of this disclosure, the water supply tube and the water absorption tube are inserted into a storage bag. The storage bag is a flexible woven fabric structure that can be rolled up and stretched. It includes a small tube bag hole and a large tube bag hole connected as an integral structure. Both ends of the storage bag are respectively provided with tightening ropes that can simultaneously tighten the openings of the small tube bag hole and the large tube bag hole at the same end.

[0015] In one exemplary embodiment of this disclosure, the cleaning drill bit also includes an integrally formed extended connecting tube, the axis of which is parallel to the symmetrical center plane of the drill bit body, and a threaded connecting joint tube for extending the forward extension of the drill bit body.

[0016] In one exemplary embodiment of this disclosure, the diameter of the extended connecting pipe is greater than the thickness of the dipper head body, the upper side of the extended connecting pipe is connected to the upper plane of the dipper head body along an arc transition, and its lower circumferential surface is connected to the lower plane of the dipper head body.

[0017] In an exemplary embodiment of this disclosure, the front end of the lower plane of the excavator head is thickened to form a front end boss.

The inner end face of the front end boss protrudes to the pipe-carrying area to provide an installation boss. An installation hole is provided on the installation boss, which is obliquely penetrating to the water suction chamber inside the excavator head for positioning and locking the threaded joint. The axis of the installation hole is perpendicular to the cleaning excavator surface. After the external connecting pipe is connected, it is located in the pipe-carrying area.

[0018] In one exemplary embodiment of this disclosure, the front end of the water suction chamber of the scraper head is blocked by the scraper face mesh plate. The middle part of the scraper face mesh plate is a water spraying area, and a water suction area is set around the water spraying area.

Detailed Implementation

[0027] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0028] This example embodiment provides a cleaning handle that is easy to operate, such as... Figures 1-3 As shown, it includes a water supply pipe 2, a suction pipe 3, a cleaning nozzle 5, and a handheld device 4; wherein,

[0029] The handheld body 4 is used for heat protection and hand grip, therefore, it should have a certain thickness and strength. It is formed by two rigid half-shells being snapped together to form its handheld shell, including the handheld part 41, the curved neck 43 and the connecting part 44. In order to facilitate cleaning of the horizontal cleaning plane below the hand or the vertical cleaning plane above the head, there should be a certain operating angle between the handheld part 41 and the connecting part 44 to improve the operating comfort. The operating angle is 120°≤140°. The handheld part 41 and the connecting part 44 are connected by the rounded corner of the curved neck 43. The handheld shell has an integrally formed positioning structure for positioning and guiding the water supply pipe 2 and the water suction pipe 3, such as the positioning post for guiding the pipeline, the positioning clamp, and the support plate for multi-point support of the internal high-temperature water supply pipe 2, etc.

[0030] The cleaning head 5 is detachably installed on the connecting part 44 at the front end of the handheld body 4. In order to facilitate the cleaning head 5 to penetrate into the gap to a sufficient depth, the cleaning head 5 does not have a bend structure. It extends forward along the axis of the connecting part 44, and its head body 51 is connected to the handheld part 41. The head body 51 has a tapered and flat structure from the front end to the rear end. It has a hollow interior with a water absorption chamber 511. The front end of the water absorption chamber 511 is blocked by the face plate 53. The nozzle 54 is set in the water absorption chamber 511 of the head body 51. The front end is connected to the face plate 53. The nozzle 54 sprays water through the spray area 531 in the middle of the face plate 53. The water absorption chamber 511 is connected to the water absorption area 532 around the spray area 531. The suction force builds a virtual splash wall to prevent high temperature cleaning water from splashing out. At the same time, since the splash plate and splash area are omitted, the structural thickness of the head body 51 can be effectively reduced.

[0031] Refer again Figure 3 In order to form a uniform suction force in the head body 51, the nozzle 54 also has a tapered and flat structure from the front end to the rear end. The threaded joint 541 integrally formed at the rear end of the nozzle 54 extends out from below the head body 51. The front end of the lower plane of the head body 51 is thickened to form a front boss 512. The nozzle 54 is located at the front end of the water suction chamber 511 and is directly opposite the front boss 512, which helps to increase the cleaning force acting on the cleaning surface. The front end is thicker than the rear end, and the area of ​​the front and rear channels of the water suction chamber 511 is uniformly and orderly reduced, which helps to form a uniform suction force.

[0032] To prioritize routine cleaning operations, the cleaning surface at the front end of the head body 51 is sloped inwards from the bottom to form a slope angle with the vertical cleaning plane, with a slope angle of 15°≤20°. The sloped cleaning surface matches the operating angle of the handheld part 41, satisfying the ergonomic operation design and facilitating observation and cleaning operations. In addition, the mesh plate 53 is wider at the top and narrower at the bottom, so that the suction is more distributed in the upper part of the water spray area 531, which better meets the suction requirements of routine operations. The side of the head body 51 transitions between the upper and lower planes of the head body 51 through the side rounded corner 515.

[0033] The routing of the water supply pipe 2 needs to consider scalding prevention and flexibility of movement. It includes an external connecting pipe 21, a control valve pipe 22, an internal water supply branch pipe 23, and a flexible water supply pipe 24. The control valve pipe 22 can be an electric or mechanical valve body, which is used to control the on / off of the water supply pipe 2. The control valve pipe 22 and the internal water supply branch pipe 23 are built into the handheld housing together. The control valve pipe 22 is locked in the handheld housing, and its outer end extends out of the end face of the connecting part 44 and is connected to one end of the external connecting pipe 21. The other end of the external connecting pipe 21 is connected to the threaded connector 541. One end of the internal water supply branch pipe 23 is connected to the control valve pipe 22, and the other end is connected to the flexible water supply pipe 24. The end of the flexible water supply pipe 24 is locked at the lower end of the handheld part 41. The flexible water supply pipe 24 is located outside the handheld housing, maintaining its original flexibility, which facilitates movement and rotation operation.

[0034] Similarly, the suction tube 3 includes a connector tube 31, an internal suction branch tube 32, and a flexible suction tube 33. The internal suction branch tube 32 and the internal water supply branch tube 23 are installed parallel to each other inside the handheld housing. The connector tube 31 is a rigid tube that is fixed inside the connecting part 44 of the handheld housing. It serves as the end positioning and intermediate connection of the internal suction branch tube 32. Its outer end extends out of the end face of the connecting part 44 for quick connection to the cleaning nozzle 5. One end of the internal suction branch tube 32 is connected to the inner end of the connector tube 31, and the other end is connected to the flexible suction tube 33. Similarly, the end of the flexible suction tube 33 is locked at the lower end of the handheld part 41. The flexible water supply tube 24 is located outside the handheld housing, maintaining its original flexibility for easy movement and rotation.

[0035] In one exemplary embodiment of this disclosure, a switch base 42 is integrally formed on the upper part of the handle 41 or at the connection between the handle 41 and the curved neck 43, facilitating cleaning and operation with one hand. The switch base 42 protrudes from the handle surface of the handle 41 and, specifically, is located on the inner handle surface to prevent collisions. Figures 1-2 As shown, the control switch 421 is located on the right side of the switch base 42. When holding the cleaner with the right hand, the water spray can be controlled by extending the index finger. The control switch 421 is electrically or mechanically connected to the control valve pipe 22.

[0036] In an exemplary embodiment of this disclosure, the handheld part 41 is cam-shaped and adapted to the diameter of the water suction pipe 3 and the diameter of the water spray pipe. The water spray pipe is located below. The lower half-arc of the handheld part 41 covers the outside of the built-in water supply branch pipe 23, and the upper half-arc covers the outside of the built-in water suction branch pipe 32. The lower half-arc surface is a small arc surface, and the upper half-arc surface is a large arc surface. The lower half-arc surface is a four-finger gripping area, and can be provided with anti-slip grooves or raised anti-slip stripes with a finger width. Furthermore, the raised anti-slip stripes can be anti-scalding inserts.

[0037] In an exemplary embodiment of this disclosure, the water delivery flexible tube 24 and the water absorption flexible tube 33 can be connected into a flexible integrated structure by one or more storage bags 1 inserted along the tube. Multiple storage bags 1 can be sequentially threaded through the pipeline to store multiple sections of the pipeline separately. The storage bag 1 includes a small tube bag hole and a large tube bag hole connected in parallel and as an integrated structure. Both ends of the storage bag 1 are respectively provided with tightening ropes that can simultaneously tighten the openings of the small tube bag hole and the large tube bag hole at the same end. After tightening the tightening ropes, the water delivery flexible tube 24 and the water absorption flexible tube 33 can be made to fit together.

[0038] The storage bag 1 has a flexible woven fabric structure, which can roll up the exposed tubing. The water delivery flexible tube 24 and water absorption flexible tube 33 exposed outside the storage bag 1 can be separated, which is convenient for bending.

[0039] In one exemplary embodiment of this disclosure, the cleaning scraper head 5 further includes an integrally formed extended connecting tube 52. The extended connecting tube 52 extends rearward along the scraper head body 51, with its axis parallel to the symmetrical center plane of the scraper head body 51. The extended connecting tube 52 is threadedly connected to a connector tube 31 to extend the forward extension of the scraper head body 51, making it easier to extend into the gap for cleaning work.

[0040] In addition, in order to increase the suction flow rate by increasing the channel area at the rear end of the extruder body 51, the diameter of the extended connecting pipe 52 is greater than the thickness of the extruder body 51. The upper circumferential surface of the extended connecting pipe 52 is connected to the upper plane of the extruder body 51 by an arc transition, and its lower circumferential surface extends to connect to the lower plane of the extruder body 51, reserving a routing channel for the external connecting pipe 21.

[0041] Specifically, the end face of the connecting part 44 of the inner end face of the front boss 512 and the lower plane of the squeegee head 51 form a pipe-carrying area 55. In order to facilitate installation and operation, the inner end face of the front boss 512 protrudes from the pipe-carrying area 55 to provide a mounting boss 514. The mounting boss 514 is provided with a mounting hole 513 that extends obliquely to the water suction chamber 511 inside the squeegee head 51. The axis of the mounting hole 513 is perpendicular to the cleaning squeegee surface. The nozzle 54 extends obliquely from the middle of the cleaning squeegee surface to the lower plane of the cleaning squeegee head 5. The root circle of the threaded joint 541 is positioned and locked in the mounting hole 513. The external connecting pipe 21 is threadedly connected to the threaded joint 541 and is pulled by the pipe-carrying area 55 to the control valve pipe 22 on the end face of the connecting part 44.
