Description

Cleaning device handle and cleaning device Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a cleaning device handle and a cleaning device. Background Art

[0002] Traditional car washes often occupy a space large enough to accommodate at least one vehicle. The washing process involves spraying water and cleaning fluid onto the vehicle body and scrubbing and rinsing it with large mechanical rollers. These systems are bulky, consume a lot of water and electricity, and are noisy. In recent years, with the rise in popularity of floor scrubbers, portable car scrubbers have emerged, evolving from "water-dust circulation" floor scrubbers. These scrubbers use a motor to drive a cleaning cylinder to wipe the vehicle body. The portable scrubbers are also equipped with a water supply system and sink to clean the cylinder, thereby cleaning the vehicle body. Because traditional car washes consume a lot of water and electricity and are noisy, portable car scrubbers are becoming increasingly popular with consumers.

[0003] The handles of some existing portable cleaning devices contain batteries, display panels, control panels, and other components, and can be quickly separated from the main body. However, some existing cleaning device handles are positioned at an angle of nearly 90° to the main body, which often results in a poor grip. In some cleaning device handles, components such as the battery are not tightly connected to the handle housing and other cleaning device components. Furthermore, the electrical connection between the handle and the main body can easily fail when subjected to significant external force. Summary of the Invention

DETAILED DESCRIPTION

[0059] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0060] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "far," "near," "front," and "back" and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0061] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0062] The inventors have discovered that the handles of existing portable cleaning devices have a poor grip, and when the handle is subjected to a large external impact, electrical connection failure between the handle and the body is likely to occur.

[0063] Based on this, the present invention provides a cleaning device handle and a cleaning device, which are described in detail below through specific embodiments.

[0064] In the first aspect, an embodiment of the present invention provides a cleaning device handle, as shown in Figures 1 to 7, the cleaning device handle includes a handle body 21A and an energy unit 50; the handle body 21A is formed by extending from the housing 20 of the cleaning device to the end; the handle body 21A is cylindrical, hollow inside and open at one end; the energy unit 50 provides power for the cleaning device, and the energy unit 50 includes a detachably connected abutment portion 50A and a clamping portion 50B, the abutment portion 50A is inserted into the handle body 21A and can slide along its axial direction to achieve abutment with the water pump assembly 10 in the cleaning device, and the clamping portion 50B can It is snap-fitted with the opening of the handle body 21A (not marked in the drawings), and the abutting portion 50A includes a shell 501 and a power supply assembly 504. The shell 501 is open at one end and semi-closed at the other end. The snap-fitting portion 50B seals the power supply assembly 504 in the shell 501 at the opening of the shell 501 (not marked in the drawings). The power supply assembly 504 includes a battery cell group 5041 and an output end 5042 that are electrically connected to each other. The output end 5042 at least partially extends out of the semi-closed end of the shell 501 (not marked in the drawings); when the snap-fitting portion 50B is snap-fitted with the handle body 21A, the output end 5042 is electrically connected to the water pump assembly 10.

[0065] Specifically, as shown in Figures 1, 6, 7 and 11, the power supply assembly 504 is accommodated in the shell 501; the shell 501 is inserted into the handle body 21A, and the clamping portion 50B is clamped with the opening of the handle body 21A to seal the power supply assembly 504 in the shell 501.

[0066] In this embodiment, referring to Figures 1 to 3, the handle body 21A is cylindrical. Compared with the existing cleaning device handle that is bent nearly 90°, the handle body 21A and the energy unit 50 are longer, the battery cell group 5041 is also more slender, and the connection between the battery cell group 5041 and the outer shell 501 is tighter, which not only improves the grip, but also improves the stability of the snap-fit ​​between the energy unit 50 and the handle body 21A.

[0067] In this way, when the user holds the handle of the cleaning device, he can directly hold the outer surface of the handle body 21A. While holding the handle body 21A tightly, the user also makes the handle body 21A and the outer shell 501 of the energy unit 50 slide and engage with each other under the positive pressure of the user's hand, and the relative sliding friction between the two increases, so that when the handle of the cleaning device is subjected to a large external force, the energy unit 50 can still maintain a reliable electrical connection with the water pump assembly 10 in the cleaning device.

[0068] In one or more optional embodiments, a depressible engaging mechanism (not shown) is provided on the outer surface of the engaging portion 50B, which engages with the opening of the handle body 21A. Providing the engaging mechanism on the outer surface of the engaging portion 50B facilitates the user to quickly separate the energy unit 50 from the handle body 21A by simply pressing the engaging mechanism to release the engaging portion 50B from the handle body 21A, thereby quickly removing the entire energy unit 50 from the handle body 21A.

[0069] In one or more optional embodiments, as shown in Figures 1, 3, and 9 to 11, the outer surface of the clamping portion 50B is flush with the outer surface of the handle body 21A; when the clamping portion 50B is clamped to the handle body 21A, the clamping end surface of the clamping portion 50B (not shown in the drawings) just blocks the open end surface of the handle body 21A (not shown in the drawings). In this way, only a small amount of the clamping portion 50B of the energy unit 50 is exposed outside the handle body 21A. When the user holds the cleaning device handle, the majority of the grip is still on the outer surface of the handle body 21A. Even if a small amount of gripping area falls on the outer surface of the clamping portion 50B, it still does not affect the user's grip on the handle body 21A. At the same time, the sliding engagement between the handle body 21A and the housing 501 of the energy unit 50 increases the relative sliding friction between the two under the positive pressure of the user's hand, so that when the cleaning device handle is subjected to a large external force, the energy unit 50 can still maintain a reliable electrical connection with the water pump assembly 10 in the cleaning device. On the other hand, as shown in FIG10 , the clamping portion 50B is only exposed on the outer surface of the handle body 21A at the very end of the handle body 21A, which makes it convenient for the user to directly press the clamping mechanism on the outer surface of the clamping portion 50B to release the clamping portion 50B from the handle body 21A. The user can then pull out the entire energy unit 50 quickly and conveniently.

[0070] In one specific embodiment, as shown in Figures 2 to 7 , the engaging mechanism includes an engaging button 502, an elastic member 503, and a guide frame 505. Specifically, as shown in Figures 6 and 7 , a pair of mating holes 5011 are disposed on the sidewalls of the housing 501; the guide frame 505 blocks the opening of the housing 501, and a guide through hole 5051 is disposed radially therefrom; the elastic member 503 is mounted in the guide through hole 5051, the engaging button 502 extends into the guide through hole 5051 and the mating hole 5011, abutting against the elastic member 503, and the engaging button 502 is engaged with the opening of the handle body 21A. Specifically, as shown in Figures 4 and 5, the snap-on button 502 includes a snap-on end 5021 and a button end 5022 connected into a whole. The snap-on end 5021 can be a hook structure that can be snapped into the inner wall groove of the handle body 21A (not marked in the drawings). The outer surface of the button end 5022 is flush with the outer surface of the handle body 21A, and the two form a smoothly transitioned whole. The exposed outer surfaces of the button end 5022 are all provided with anti-slip grooves, which can prevent the user from slipping while holding the handle body 21A, causing the cleaning device to fall out of the hand and break. At the same time, it also helps to remind the user through touch that the button end 5022 is different from other parts of the handle body 21A, and reminds the user that the energy unit 50 can be separated from the handle body 21A by pressing the snap-on button 502.

[0071] In this embodiment, as shown in Figures 1 to 7, the energy unit 50 is connected to the handle body 21A via a snap button 502. Since the snap button 502 abuts the elastic member 503, the snap end 5021 of the snap button 502 can abut against the inner wall of the handle body 21A under the elastic force of the elastic member 503. Moreover, when the housing 501 is inserted into the handle body 21A, the snap end 5021 is snapped with the inner wall of the handle body 21A, and the button end 5022 is located outside the handle body 21A. Pressing the button end 5022 can compress the elastic member 503, facilitating the removal of the energy unit 50 from the handle body 21A. The outer surface of the button end 5022 of the snap button 502 is flush with the outer surface of the housing 501. When the cleaning device handle is held, the snap button 502 is not subjected to any force alone and thus cannot be accidentally pressed.

[0072] In one or some optional embodiments, as shown in Figures 6, 7, and 11, a pole piece receiving hole 5012 is provided at the semi-enclosed end of the housing 501 of the abutment portion 50A, and the output end 5042 of the power supply assembly 504 at least partially extends out of the pole piece receiving hole 5012 to achieve electrical connection between the output end 5042 and the power supply electrode (not shown in the drawings) of the water pump assembly 10. Providing the pole piece receiving hole 5012 at the semi-enclosed end of the housing 501 facilitates the output end 5042 of the power supply assembly 504 to at least partially extend out of the pole piece receiving hole 5012. When the electrical connection between the output end 5042 and the power supply electrode of the water pump assembly 10 is poor due to ablation or oxidation between the two, it is convenient for the user to promptly replace and maintain the output end 5042.

[0073] In one embodiment, as shown in Figures 2, 3, 9, and 10, the output terminal 5042 includes a positive electrode sheet 50422, a negative electrode sheet 50423, and an electrode sheet support frame 50421. The battery cell assembly 5041 is placed between the guide frame 505 and the electrode sheet support frame 50421, and abuts the guide frame 505 and the electrode sheet support frame 50421 respectively. A raised electrode placement portion 50421a is provided at one end of the electrode support frame 50421 away from the battery cell group 5041, and the positive electrode 50422 and the negative electrode 50423 are respectively placed on the electrode placement portion 50421a, and the electrode placement portion 50421a extends out of the electrode accommodating hole 5012. The two output poles (not marked in the accompanying drawings) of the battery cell group 5041 are electrically connected to the positive electrode 50422 and the negative electrode 50423 respectively. The positive electrode 50422 and the negative electrode 50423 can be electrically connected to the power taking electrodes of the water pump assembly 10 respectively, thereby realizing a detachable electrical connection between the energy unit 50 and the cleaning device water pump assembly 10, so that the energy unit 50 can supply power to the water pump assembly 10 and can be removed for charging when the power is insufficient.

[0074] In a specific embodiment, as shown in Figures 1 and 7, two electrode placement portions 50421a can be provided, one for placing the positive electrode 50422 and the other for placing the negative electrode 50423. Correspondingly, two electrode accommodating holes 5012 are provided. The two electrode placement portions 50421a, each equipped with the positive electrode 50422 and the negative electrode 50423, extend out of the corresponding electrode accommodating holes 5012 and are electrically connected to the two power-taking electrodes of the water pump assembly 10, thereby further improving the compactness and stability of the structure.

[0075] The present invention provides a cleaning device handle of an embodiment, in which the handle body 21A is used in conjunction with an elastic member 503 and a snap-on button 502 to achieve a tight snap connection between the energy unit 50 and the handle body 21A, and the output end 5042 of the power supply assembly 504 is arranged to at least partially extend out of the shell 501 and be electrically connected to the water pump assembly 10, thereby achieving a detachable electrical connection between the cleaning device handle and the cleaning device, and the power supply assembly 504 is arranged in the shell 501 and a guide frame 505 is arranged to abut the power supply assembly 504, so that the power supply assembly 504 is firmly installed, and the handle body 21A is cylindrical, which improves the convenience of holding compared to the existing cleaning device handle that is bent nearly 90°, and while ensuring the detachable electrical connection, the stability of the component installation is improved, and electrical connection failure is less likely to occur, thereby avoiding the energy unit built into the cleaning device handle from being detached under the action of impact.

[0076] In a specific embodiment, as shown in Figures 5 and 7, the energy unit 50 may further include a buffer pad 506 disposed between the guide frame 505 and the battery pack 5041. The buffer pad 506 can provide a buffer for the battery pack 5041 when the energy unit 50 or the cleaning device handle as a whole is impacted, and can also help reduce vibration when the cleaning device is operating, thereby protecting the power supply assembly 504, preventing the power supply assembly 504 from loosening or being damaged, and ensuring that the electrical connection between the power supply assembly 504 and the water pump assembly 10 is not easily invalidated. The material of the buffer pad 506 can be sponge, etc., and the specific details can be referred to the detailed description in the prior art, and are not limited here.

[0077] In a specific embodiment, as shown in Figures 2 to 4, 6, 7, and 11, the energy unit 50 may further include an end cap 507 and a sealing cap 508. The end cap 507 is provided on the end of the clamping portion 50B away from the cleaning device housing 20, and a charging head (not shown in the drawings) is provided through the middle of the end cap 507. The sealing cap 508 is provided on the end of the end cap 507 away from the housing 501 and is interference-fitted with the sealing cap 508 to seal the outer end of the end cap 507. This prevents the charging head on the end cap 507 from being splashed by water when not charging and causing a short circuit. Specifically, a sealing plug 5081 is provided on the end surface of the sealing cap 508 facing the end cap 507. The end cap 507 is correspondingly provided with a sealing plug receiving hole 5071. The sealing plug 5081 can extend into the sealing plug receiving hole 5071 and interference-fit with the sealing plug receiving hole 5071 to achieve a sealed connection between the sealing cap 508 and the end cap 507. Since the guide frame 505 blocks the open end of the housing 501 , after the end cover 507 and the sealing cover 508 are combined to seal the clamping portion 50B, the guide frame 505 can abut against the inner end surface of the end cover 507 .

[0078] In one specific embodiment, as shown in Figures 2, 3, 10, 13, and 14, the energy unit 50 further includes a charge control board 509 and an insulating light guide plate 510. The charge control board 509 and the insulating light guide plate 510 are housed within the clamping portion 50B and are respectively sleeved on the guide frame 505. Specifically, one or more support columns 5052 are provided at one end of the guide frame 505 facing the end cap 507. Accordingly, the charge control board 509 is provided with a corresponding number of first fixing holes 5091, and the insulating light guide plate 510 is provided with a corresponding number of second fixing holes 5101. The support columns 5052 pass through the corresponding first fixing holes 5091 and second fixing holes 5101, thereby achieving the installation and fixation of the charge control board 509 and the insulating light guide plate 510. The charging control board 509 is positioned near the battery pack 5041 and is electrically connected to the charging head. The charging control board 509 is also electrically connected to the input and output terminals of the battery pack 5041. The charging control board 509 can control whether to charge the entire battery pack 5041 based on the voltage between the individual cells in the battery pack 5041. The insulating light guide plate 510 is positioned near the end cap 507. The charging control board 509 is provided with a raised light-emitting portion 5092, and the sealing cap 508 is provided with a corresponding light-transmitting portion 5082. The light-emitting portion 5092 passes through the insulating light guide plate 510 and the end cap 507, abutting against the light-transmitting portion 5082 of the sealing cap 508. Therefore, the light emitted by the light-emitting portion 5092 can be seen through the light-transmitting portion 5082. Furthermore, the charging control board 509 is electrically connected to the power supply assembly 504 and the water pump assembly 10. When the water pump assembly 10 is in different working modes, the light-emitting portion 5092 of the charging control board 509 can emit lights of different colors, thereby serving as an indication.

[0079] In one specific embodiment, as shown in Figures 6 and 7 , the energy unit 50 may further include a light guide column 511 and a light shielding ring 512 disposed around the light guide column 511. The light guide column 511 is disposed around the outer periphery of the charging control board 509 and the insulating light guide plate 510. The light guide column 511 can transmit light emitted by the light-emitting portion 5092, while the light shielding ring 512 can shield the light transmitted through the light guide column 511, confining the light within the light shielding ring 512 so that the light accurately reaches the light-transmitting portion 5082 of the sealing cover 508, ensuring that the light clearly transmits through the light-transmitting portion 5082, thereby indicating the operating mode of the water pump assembly 10. The number of light shielding rings 512 can be one or more, and can be appropriately set according to actual needs.

[0080] In a specific embodiment, as shown in FIG7 , the energy unit 50 may further include an insulating sheet 513 between the electrode support frame 50421 and the housing 501. The insulating sheet 513 may be provided with the same number of insulating sheet 513 through-holes as the electrode placement portions 50421a. The electrode placement portions 50421a are electrically connected to the water pump assembly 10 after passing through the corresponding insulating sheet 513 through-holes. The insulating sheet 513 can seal and isolate the electrode support frame 50421 from external components, thereby improving the safety of the external output of the battery cell group 5041.

[0081] In one specific embodiment, as shown in Figures 1, 2, 4, 6, and 7, the outer wall of the housing 501 is provided with a guide groove 5013, and the inner wall of the handle body 21A is provided with a guide strip (not shown). The guide strip cooperates with the guide groove 5013, and the guide groove 5013 circumferentially constrains the guide strip, thereby improving the connection stability between the energy unit 50 and the handle body 21A. When the energy unit 50 is installed in the handle body 21A, the end of the guide strip aligns with the end of the guide groove 5013, and the guide strip slides along the guide groove 5013 until the engaging end 5021 of the engaging button 502 engages with the inner wall of the handle body 21A. Furthermore, the guide grooves 5013 can be unevenly distributed circumferentially on the outer wall of the housing 501, so that the guide grooves 5013 can be used to identify the installation direction. For example, three guide grooves 5013 can be provided on one side and two guide grooves 5013 on the other side. The number of guide grooves 5013 can be used to determine the installation direction, thereby ensuring installation efficiency.

[0082] In one specific embodiment, as shown in FIG3 , a cell sealing ring 514 can be provided at the junction of the cell group 5041 and the guide frame 505 to seal the gap between the guide frame 505 and the housing 501, thereby enclosing the cell group 5041 within the housing 501 and sealing and securing the outer periphery of the end of the cell group 5041. A housing sealing ring 515 can be provided at the junction of the housing 501 and the handle body 21A to seal and secure the abutting portion 50A of the energy unit 50 within the handle body 21A.
