Description

[0001] This application is a divisional application of Chinese patent application No. 202410295671.9 and invention name “A straight-handle car washing machine”, the contents of which are incorporated herein by reference. Technical Field

[0002] The invention relates to the technical field of cleaning equipment, and in particular to a straight-handled car washing machine. Background Art

[0003] In modern society, car washing has become a basic need for vehicle maintenance. However, traditional car washing devices have obvious limitations and shortcomings due to their design and operation mode. These devices often need to occupy at least a space that can accommodate a whole car, and during the car washing process, the body needs to be sprayed with clean water and cleaning liquid, and then the body needs to be scrubbed and rinsed by large mechanical rollers. This car washing method not only makes the entire car washing device bulky, but also consumes a lot of water and electricity during use, and the operating noise is relatively high; in recent years, with the popularization of floor scrubbers, the technical evolution and iterative development of "water-dust circulation" floor scrubbers have spawned portable car scrubbers. This new type of equipment uses a motor to drive the cleaning cylinder to scrub the car body, and the built-in water supply system and sink can effectively clean the cleaning cylinder, thereby achieving the purpose of recycling water resources.

[0004] Chinese patent CN218287692U of the prior art discloses an electric scrubbing vehicle tool, comprising an electric scrubbing head and a handle connected to the electric scrubbing head, wherein a circulating water tank for cleaning and collecting circulation is provided on the handle, wherein the circulating water tank comprises a water tank body provided with a first cavity, wherein the water tank body is provided with a water inlet and outlet mechanism for allowing water to enter or discharge the first cavity, wherein the water tank body is further provided with a pressure relief mechanism communicating with the inside and outside of the first cavity, wherein the pressure relief mechanism comprises a second cavity and a third cavity independently arranged from the first cavity, wherein a filter screen is provided between the second cavity and the first cavity, wherein an air passing component is provided between the third cavity and the second cavity, and wherein the third cavity is communicated with an exhaust nozzle communicating with the outside.

[0005] However, there is still a problem: since the cleaning head at one end of the existing portable car washing machine is heavy, and the handle at the other end and the body where the battery is placed are bent nearly 90 degrees, when in use, it causes the user to have difficulty holding the handle and the gripping feeling is poor. At the same time, when subjected to external force impact, it is easy to cause the electrical connection between the handle and the body to fail. It can be seen that it is necessary to provide a more stable and ergonomically designed grip handle to reduce the user's grip pressure and improve comfort, while strengthening the connection between the handle and the body and improving the stability of the structure.

[0056] The following further elaborates on the claims of the present invention in conjunction with specific embodiments and the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention also fall within the scope of protection of the present invention.

[0057] It should be understood that in the description of the embodiments of the present invention, all terms indicating directional indications, such as "upper", "lower", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation and positional relationship shown in the drawings, or the orientation or positional relationship when the product of the present invention is usually placed during use. It is only for the convenience of simplifying the description of the present invention, rather than explicitly or implicitly indicating that the device, element or component must have a specific orientation and a specific orientation structure. It should not be construed as a limitation of the present invention. It is only used to explain the relative positional relationship and movement conditions between the components under the shown drawings. When this specific posture changes, the directional indication may also change accordingly. For processes and methods, unless it is clearly recorded in the specification that each step must be carried out in sequence and the sequence change of each step is excluded, otherwise, except for those that cannot achieve the corresponding invention purpose, it is regarded as for the simplicity of description. The specification only takes the optimal or better examples selected from various implementation manners for illustration.

[0058] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, the positional relationship between components can be relatively fixed, or the components can be physically fixedly connected. They can be detachable or integrated. They can be mechanically connected or electrically connected. They can be directly connected or indirectly connected through an intermediate medium or component. They can be internally connected between two elements or interact with each other. Unless otherwise clearly defined in the specification, other interpretations may not achieve the corresponding functions or effects. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0059] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention. The present invention is further described below in conjunction with specific embodiments, but is not intended to limit the present invention.

[0060] The handle of a portable car washing machine in the prior art adopts a structure that is bent at nearly 90 degrees. For example, Chinese patent CN218536624U discloses a car wiping device with a pressure relief function, including a body, a shell connected to the front end of the body, and a handle connected to the end of the body. The cleaning mechanism is installed in the shell, the pump and part of the delivery pipeline in the cleaning liquid delivery mechanism are installed in the body, part of the delivery pipeline in the cleaning liquid delivery mechanism, and a section of the wiping roller in the pipeline of the cleaning liquid delivery mechanism that passes through the cleaning mechanism are installed in the shell, the control circuit board, battery, and display panel of the car wiping device are installed in the handle, and the body, shell, and handle are all arranged with a power harness, a signal harness, and a connector to provide power or sensor signal transmission to the car wiping device.

[0061] However, when in use, since one end of the cleaning head is heavy, when the user holds the handle bent at nearly 90 degrees, there are problems of effort and poor grip. At the same time, when subjected to external force impact, it is easy to cause the electrical connection between the handle and the body to fail. Therefore, in order to provide a more stable and ergonomically designed grip handle to reduce the user's grip pressure and improve comfort, while strengthening the connection between the handle and the body and improving the stability of the structure, the present invention is made.

[0062] The present invention will be further described below in conjunction with specific embodiments, but the present invention is not limited thereto.

[0068] Figure 9 This is a perspective view of one angle of the straight-handle car washer of the present invention without the cleaning roller installed, Figure 10 This is another perspective view of the straight-handle car washer of the present invention without the cleaning roller installed, showing the arrangement of multiple exhaust ports where the exhaust passage of the water tank of the straight-handle car washer is connected to the decontamination device of the upper cover assembly.

[0069] As Figures 1 - 10As shown in the figure, the present invention provides a straight-handle car washer, which includes a cleaning roller assembly 30, a housing assembly 20, a water tank 40, a battery assembly 50, and a water pump assembly 10; the cleaning roller assembly 30 is rotatable and its wet outer surface elastically presses against and scrubs the surface of the vehicle body to be cleaned; the housing assembly 20 includes a bottom shell 21 and an upper shell 22, the upper shell 22 covers the bottom shell 21, the bottom shell 21 extends forward to form a U-shaped structure to clamp both ends of the cleaning roller assembly 30, the bottom shell 21 extends to the end to form a straight cylindrical handle 21B, and the handle has a receiving cavity inside, and one end of the handle 21B has an opening; the water tank 40 is detachably clamped to the upper shell 22, and the water tank 40 provides clear water to the surface of the cleaning roller assembly 30 through a clear water channel (not marked in the drawing) between the water tank 40 and the surface of the cleaning roller assembly 30, and collects the sewage squeezed out from the surface of the cleaning roller assembly 30 through a sewage channel (not marked in the drawing) between the water tank 40 and the surface of the cleaning roller assembly 30; the battery assembly 50 includes a waterproof part 501 and a docking part 502, the docking part 502 is detachably installed in the receiving cavity of the handle 21B through the opening, the docking part 502 is provided with an output terminal, and the waterproof part 501 closes the opening; the water pump assembly 10 includes a power connection terminal 10A and a water inlet and outlet terminal 10B, and is installed in the housing assembly 20, and the power connection terminal 10A is elastically electrically connected to the output terminal of the battery assembly 50; wherein, the battery assembly 50 provides power for the water pump assembly 10, the water pump assembly 10 pumps clear water from the water tank 40, and the water tank 40 also collects sewage.

[0070] Further, as Figure 2 , Figure 7 shown in the figure, a conduction channel (not marked in the drawing) is communicatively provided between the upper shell 22 and the bottom shell 21 of the housing assembly 20, the water pump assembly 10 is clamped in the conduction channel and installed adjacent to the battery assembly 50, the power connection terminal 10A of the water pump assembly 10 is elastically electrically connected to the output terminal of the battery assembly 50 in the conduction channel, and the water inlet and outlet terminal 10B of the water pump assembly 10 is connected to the clear water channel and the sewage channel in the conduction channel, conveys the clear water pumped out from the water tank 40 to the surface of the cleaning roller assembly 30, and collects the sewage squeezed out from the surface of the cleaning roller assembly 30 back into the water tank 40.

[0071] In this way, by setting the handle to have a columnar straight handle structure for accommodating the battery assembly, compared with the structural setting of the prior art in which the handle and the body where the battery is placed are bent nearly 90 degrees, the joints and muscles of the hand are in a more comfortable position when holding. When one end of the cleaning head is heavier and causes the center of gravity of the car washing machine to shift, the straight handle setting can distribute the weight more evenly, reduce the sense of imbalance, and reduce the effort during use. At the same time, the straight handle structure is more stable, and it is easier to control the movement direction and strength of the car washing machine when holding, reducing the extra force consumption caused by unstable control; by extending the bottom shell of the outer shell assembly to the end to form a straight cylindrical handle, so that the water pump assembly installed in the outer shell assembly is electrically connected to the battery assembly installed in the handle, the battery assembly and the water pump assembly are integrated and installed at the corner of the handle and the bottom shell, simplifying the circuit design and connection method. This structure reduces deformation during external force impact, avoids the problem of the outer shell assembly being easily broken or loosened at the corner of the handle, improves the structural stability of the product, improves the reliability of the electrical connection, and avoids the problem of electrical connection failure. In addition, when the user holds the handle of the cleaning device, the user can directly hold the outer surface of the handle. While holding the handle tightly, the user also causes the handle and the outer shell of the battery assembly to slide and engage with each other under the positive pressure of the user's hand, which increases the relative sliding friction between the two. This allows the battery assembly to maintain a reliable electrical connection with the water pump assembly in the cleaning device when the handle of the cleaning device is subjected to a large external force impact.

[0072] In one or some alternative embodiments, Figure 1 , Figure 3 , Figure 4 , Figures 8 to 10 As shown, the waterproof part 501 of the battery assembly 50 is provided with a snap-in component 5011, and the side wall of the battery assembly 50 is provided with a connecting groove 503, and the connecting groove 503 is extended along the port of the docking part 502 of the battery assembly 50 toward the waterproof part 501. The battery assembly 50 is positioned through the connecting groove 503 and extends into the accommodating cavity of the handle 21B, and is fixed at the opening of the handle 21B in cooperation with the snap-in component 5011.

[0073] Specifically, the battery assembly 50 is accurately positioned through the connection groove 503 and extends into the accommodation cavity of the handle 21B. The clamping member 5011 provided on the waterproof portion 501 is used to fix the battery assembly 50 at the opening of the handle 21B. By providing the clamping member 5011 and cooperating with the connection groove 503, the problem that the battery assembly 50 moves or is displaced during vibration when the car washer is working is avoided. At the same time, the connection groove 503 extends from the port of the docking portion 502 of the battery assembly 50 towards the waterproof portion 501. A waterproof rubber ring 5012 is sleeved between the end point of the extension of the connection groove 503 and the end face of the waterproof portion 501 close to the connection groove 503. After the battery assembly 5 is connected to the handle 21B, the waterproof rubber ring 5012 effectively seals the opening of the handle 21B, preventing moisture or dampness from entering the accommodation cavity of the handle 21B and further entering the interior of the battery assembly 50 or affecting the electrical connection between the output end of the battery assembly 50 and the power connection end 10A of the water pump assembly 10, maintaining the dry state of the battery assembly 50, and preventing the decline or failure of battery performance caused by moisture intrusion.

[0074] In one or some alternative embodiments, as Figures 1 to 4 、 Figure 8 shown, the housing assembly 20 includes a bottom shell 21 and an upper shell 22 covering the bottom shell 21. The upper part of the bottom shell 21 is open, and the connection and transition part between the upper part of the bottom shell 21 and the handle 21B is bent at an angle; a plurality of positioning parts are provided on the side wall of the bottom shell 21 to enable the detachable connection between the bottom shell 21 and the upper shell 22.

[0075] Specifically, the bottom shell 21 includes a cleaning head bottom shell 21A and a handle 21B. The connection and transition part between the cleaning head bottom shell 21A and the handle 21B is bent at an angle. The upper part of the cleaning head bottom shell 21A is open, facilitating the assembly of the water pump assembly 10. At the connection part between the lower part of the cleaning head bottom shell 21A and the handle 21B, its outer contour is smoothly curved. Cooperating with the straight-handled handle 21B, the handle 21B and the cleaning head bottom shell 21A are connected in a curve. When the user holds the straight-handled handle 21B, the housing assembly 20, as the connecting component between the handle 21B and the front cleaning roller assembly 30, the curved design can make the device more naturally adapt to the working hand shape of the user, reduce fatigue during long-term use, and improve the comfort of the user when holding.

[0076] In one or some alternative embodiments, as Figures 1 to 4As shown, after the upper shell 22 and the bottom shell 21 are covered, a cavity for installing the water pump assembly 10 is formed inside (not marked in the attached drawing). A wire groove for circuit wiring and a pipeline channel for water pipe circulation are provided at the bottom of the cavity (not marked in the attached drawing). The pipeline channel includes a water outlet pipe 10a and a water return pipe 10b that communicate with the water pump assembly 10. A wire groove for routing the wire harness cable 10c is provided at the bottom of the cavity.

[0077] Specifically, after the upper shell 22 and the bottom shell 21 are covered, a cavity for protecting the water pump assembly 10 is formed. A wire groove and a pipeline channel are provided at the bottom of the cavity. The wire groove is used to fix the wire harness cable 10c that is electrically connected to the cleaning roller assembly 30 clamped in front of the water pump assembly 10 and the housing assembly 20. The pipeline channel includes a water outlet pipe 10a and a water return pipe 10b that communicate with the water pump assembly 10.

[0078] In one or some alternative embodiments, as Figures 1 to 3 、 Figure 6 shown, a cleaning roller assembly 30 is clamped at one end of the housing assembly 20 away from the handle 21B. The cleaning roller assembly 30 includes a drive motor 30a and a cleaning roller 30b sleeved on the output rotating shaft (not marked in the attached drawing) of the drive motor 30a. The water outlet pipe 10a and the water return pipe 10b of the water pump assembly 10 transport the clear water in the water tank 40 to the surface of the cleaning roller 30b and recover the sewage from the surface of the cleaning roller 30b to the water tank 40. When the drive motor 30a works, its output rotating shaft rotates and drives the cleaning roller 30b to rotate. The cleaning roller 30b elastically abuts against the vehicle body to be cleaned. The cleaning roller 30b continuously wetted by the clear water rotates to continuously scrub the vehicle body, and the sewage after scrubbing the vehicle body is further collected by the water tank 40.

[0079] In one or some alternative embodiments, as Figure 1 、 Figure 4 shown, the cleaning head bottom shell 21A of the bottom shell 21 extends forward to form a U-shaped structure to clamp both ends of the cleaning roller assembly 30. The cleaning head bottom shell 21A includes a cleaning head left clamping plate 21A1, a cleaning head right clamping plate 21A2, and a cleaning head bottom shell body (not marked in the attached drawing) connecting the two. Specifically, as Figure 4 、 Figure 5As shown, one end of the driving motor 30a is fixed on the left clamping plate 21A1 of the cleaning head. A cleaning roller 30b is sleeved on the output shaft at the other end of the driving motor 30a. An elastic snap button (not shown in the drawing) is provided at the other end of the cleaning roller 30b, and the elastic snap button is snap-connected to the right clamping plate 21A2 of the cleaning head.

The spring 2213 applies a horizontal elastic force to the locking rod 2214 by its elasticity, so that the locking rod 2214 can move horizontally elastically.

[0087] In one or some alternative embodiments, as Figure 5As shown, a water pipe interface (not marked in the attached drawing) connecting the clean water pipe 10a and a sewage recovery port (not marked in the attached drawing) connecting the sewage pipe 10b are provided on the bottom shell 21 near the surface of the cleaning roller 30b. The water pipe interface communicates with the clean water pipe 10a, and the sewage recovery port communicates with the sewage pipe 10b. The clean water pipe 10a and the sewage pipe 10b communicate with the water tank 40. The clean water pipe 10a, the water pipe interface, the sewage recovery port, and the sewage pipe 10b form a sewage channel and a clean water circulation channel provided on the bottom shell 21.

[0088] Further, as Figure 5 、 Figure 6 shown, a water squeezing tip P that elastically abuts against the surface of the cleaning roller 30b and points to the axis of the cleaning roller 30b is provided on the bottom shell 21A of the cleaning head. The water squeezing tip P penetrates the entire outer surface of the cleaning roller 30b along the extending direction of its axis. As Figure 5 、 Figure 6 shown, a detachable spatula strip assembly 21D is also detachably connected to the lower surface of the bottom shell 21A of the cleaning head near the surface of the cleaning roller 30b. A water supporting tip Q that elastically supports the surface of the cleaning roller 30b is provided on the detachable spatula strip assembly 21D and points to the surface of the cleaning roller 30b. The water supporting tip Q penetrates the entire outer surface of the cleaning roller 30b along the extending direction of its axis. The water squeezing tip P, the water supporting tip Q, the lower surface of the bottom shell 21A of the cleaning head clamped between the two, and the outer surface of the cleaning roller 30b clamped between the two jointly enclose a water guiding space M for the flow of clean water and sewage. As Figure 5 shown, after the clean water is ejected from the water pipe interface, it directly enters the water guiding space M. In the water guiding space M, the clean water is infiltrated and absorbed by the outer surface of the cleaning roller 30b. At the same time, as the cleaning roller 30b rotates, the water squeezing tip P squeezes out the sewage in the cleaning roller 30 and guides it along the water supporting tip Q to the water guiding space M, and then the sewage is pumped away from the sewage recovery port. During the process of the entire cleaning roller 30b cleaning the surface of the vehicle body to be cleaned, the water guiding space M is used to continuously replace the clean water and sewage on the surface of the cleaning roller 30b until the surface of the vehicle body is wiped clean.

[0089] In one or some alternative embodiments, as Figure 5 shown, a sewage perspective window 21C is further provided at the interface of the sewage channel near the water guiding space M. The upper surface of the sewage perspective window 21C directly protrudes out of the outer surface of the upper shell 22A of the cleaning head. The sewage perspective window 21C is made of a transparent material. Through the sewage perspective window 21C, the sewage flow situation in the sewage channel can be directly observed to judge the degree of sewage contamination, so that the user can anticipate in advance whether it is necessary to promptly dump the sewage, add clean water, or clean the filtering device (not marked in the attached drawing) in the water tank 40.

[0090] In one or some alternative embodiments, as Figure 1 , Figure 6 , Figure 10 shown, an exhaust outlet 21A3 and an exhaust pipe 40a are further provided on the bottom shell 21A of the cleaning head. The exhaust outlet 21A3 is communicated with the water tank 40 through the exhaust pipe 40a to adjust the pressure in the water tank 40. In a preferred embodiment, a plurality of exhaust outlets 21A3 are provided. The plurality of exhaust outlets 21A3 are arranged at intervals and are simultaneously connected to the exhaust pipe 40a to adjust the pressure in the water tank 40. As the cleaning roller 30b rotates, the exhaust outlet 21A3 can discharge the air in the water tank 10 to the surface of the cleaning roller 30b after being squeezed by the water squeezing tip P. In other words, the air discharged from the water tank 10 will not be discharged to the water guiding space M, so that the replacement of clean water and sewage in the water guiding space M is more stable and the cleaning effect is better.

[0091] In one or some alternative embodiments, as Figures 1 to 3 shown, a display panel (not shown in the drawings) is provided in the waterproof part 501 to monitor the working state and battery health of the battery assembly 50, and at the same time, the display panel also monitors the working state of the entire car wash in real time.
