However, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, except for operations that must occur in a particular order, changes may be made that will be apparent upon understanding the disclosure of this application. Furthermore, descriptions of features known in the art may be omitted for clarity and brevity.

[0025] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways to implement the methods, devices, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0026] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, it may be directly “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, or one or more other elements may be present between them.

[0031] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the drawings may occur. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include changes in shapes that occur during manufacturing.

[0032] The features of the examples described herein can be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0033] The utility model provides a self-service car washing machine, such as Figure 1 As shown, the self-service car wash machine in this embodiment includes a water module, a detergent module, a liquid outlet module, and a switch module. The water module can output fresh water, the detergent module can output different detergents, and the switch module can adjust the operating states of the water module and detergent module accordingly. The following describes in detail the specific structure and connection relationship of each of these components of the self-service car wash machine according to the present invention.

[0034] In this embodiment, if Figure 1 As shown, the clean water module includes a water tank 10 and a clean water branch 11 that are connected in sequence. Specifically, a first low liquid level sensor 100 and a high liquid level sensor 101 are provided on the side of the water tank 10. The first low liquid level sensor 100 and the high liquid level sensor 101 are located on the bottom and top sides of the water tank 10, respectively. Furthermore, a water injection branch 103 is formed on the top of the water tank 10. A first solenoid valve 102 is provided on the water injection branch 103. Both the first low liquid level sensor 100 and the high liquid level sensor 101 are electrically and / or communicatively connected to the first solenoid valve 102. Thus, when the first low liquid level sensor 100 is triggered, the first solenoid valve 102 opens accordingly to enable water to be replenished into the water tank 10 through the water injection branch 103. When the water is replenished to the point where the high liquid level sensor 101 is triggered, the first solenoid valve 102 closes accordingly to stop the water replenishment.

[0035] It should be noted that there are no specific restrictions on the type and specifications of the first low liquid level sensor 100 and the high liquid level sensor 101, as long as they can achieve the above-mentioned technical effects. Furthermore, the specific locations of the first low liquid level sensor 100 and the high liquid level sensor 101 are also not fixed and can be determined based on actual needs. Furthermore, the water inlet of the water injection branch 103 can be connected to the municipal water supply pipeline to ensure timely and smooth water replenishment.

[0036] In this embodiment, the clean water branch 11 is connected to the bottom of the water tank 10, which can improve the smoothness of water flow. The clean water branch 11 is provided with a first valve assembly, which includes a manual valve 110 and a second solenoid valve 111 arranged in sequence. The manual valve 110 is normally open, that is, the flow of the clean water branch 11 is determined by the opening or closing of the second solenoid valve 111. However, when the device requires maintenance, the manual valve 110 needs to be manually closed to prevent excessive water outflow and damage to components.

[0037] In this embodiment, if Figure 1 As shown, the detergent module includes multiple parallel submodules, each of which is equipped with a detergent tank 20 and a detergent branch 21 connected in sequence. Different detergent tanks 20 are filled with different types of detergents, and each detergent branch 21 is provided with a second valve assembly. The opening and closing of the second valve assembly can control the opening and closing of the corresponding detergent branch 21, so that the user can flexibly select the corresponding detergent according to the type of stain on the vehicle. It should be noted that the number of submodules is not fixed and should be determined by the number of detergent types. For example, the detergent module in this embodiment is equipped with four submodules, and the corresponding detergent tanks 20 are respectively filled with foaming agent, shellac remover, wheel hub cleaner, and water wax. This can achieve the cleaning of different stains on the vehicle and can achieve vehicle maintenance.

[0038] Furthermore, within each submodule, each detergent branch 21 is connected to the bottom of the corresponding detergent tank 20, facilitating smooth detergent flow. Furthermore, the second valve assembly includes a meter 210 and a third solenoid valve 211, arranged in sequence. The meter 210 enables quantitative output of detergent to ensure effective cleaning, while the third solenoid valve 211 controls the opening and closing of the corresponding detergent branch. Furthermore, a second low-liquid-level sensor 200 is located on the bottom of each detergent tank 20. When triggered, the corresponding detergent can be manually added.

[0039] In this embodiment, the clean water and detergent output by the above-mentioned clean water module and detergent module are both exported through the liquid outlet module. Specifically, the liquid outlet module is formed with a liquid outlet branch 30, and the clean water branch 11 and each detergent branch 21 are connected to the liquid outlet branch 30, that is, the clean water branch 11 and the detergent branch 21 are formed in parallel. The liquid outlet branch 30 is sequentially provided with a static mixer 300, a flow meter 301, a plunger pump 302 and a water gun assembly (all of which belong to existing devices). In particular, the water gun assembly in this embodiment includes a clean water gun 303 and a detergent gun 304 arranged in parallel. When the user only needs to use clean water, the clean water gun 303 is used; and when the user needs to use detergent, the detergent gun 304 is used accordingly, so that the cleaning effect of the vehicle can be guaranteed.

[0040] The switch assembly in this embodiment includes a first switch 41 electrically connected or communicatively connected to the second solenoid valve 111. The switch assembly also includes a plurality of second switches 42 electrically connected or communicatively connected to the third solenoid valve 211 in a one-to-one correspondence. Furthermore, the switch assembly includes a PCB controller 40, through which the first switch 41 and the second switch 42 are electrically and / or communicatively connected to the second solenoid valve 111 and the third solenoid valve 211.

[0041] When the user uses the car washing machine, the user can first press the first switch 41, at which time the second solenoid valve 111 is opened and each third solenoid valve 211 is closed, so that the clean water branch 11 is connected to the liquid outlet branch 30, and the clean water is discharged by the clean water gun 303; then, the user can select the corresponding cleaning agent according to the stains on the vehicle body, that is, press the corresponding second switch 42, at which time the second solenoid valve 111 and the corresponding third solenoid valve 211 are both opened, so that the clean water branch 11 and the corresponding cleaning agent branch 21 are connected to the liquid outlet branch 30, the cleaning agent and clean water are evenly mixed in the static mixer 300 and discharged through the flow meter, plunger pump 302 and cleaning agent gun 304 to rinse the vehicle body; after the cleaning agent has fully softened and decomposed the stains, the user scrubs the vehicle body, and then presses the first switch 41, at which time the second solenoid valve 111 is opened and each third solenoid valve 211 is closed, and the vehicle is rinsed by the clean water gun 303.

[0042] It should be noted that the on-off control of the valve by the switch and the PCB controller 40 is a conventional technical means in this field, so the control logic will not be elaborated in detail. In addition, the first low liquid level sensor 100 and the high liquid level sensor 101 can also realize the on-off control of the first solenoid valve 102 through the PCB controller 40. In addition, Figure 1As shown, the meter 210, second low liquid level sensor 200, and flow meter 301 can also be communicatively or electrically connected to the PCB controller 40 to facilitate the above-mentioned technical effects. For example, when the clean water module is activated, clean water flows through the flow meter 301, and the flow meter 301 feeds back a pulse signal to the PCB controller 40, allowing its flow rate to be accurately monitored. However, if the clean water module is activated and the flow meter 301 does not output a signal, it indicates that no clean water is flowing through the flow meter 301, indicating that the water tank 10 is short of water.

[0043] It needs to be further explained that, Figure 1 In the figure, the solid line represents the physical pipeline, and the dotted line represents the electrical connection or communication connection. In addition, the meter 210 can detect the output of the cleaning agent, and according to the data such as the diameter of the clean water branch 11, the mixing ratio of the cleaning agent can be ensured to ensure its cleaning effect.

[0044] According to the self-service car washing machine of the present invention, a clean water module capable of outputting clean water (through the liquid outlet module) and a detergent module capable of outputting different types of detergents (through the liquid outlet module) are provided. When the user starts to wash the vehicle, the first valve component on the clean water branch 11 is adjusted to the open state through the switch component to output clean water to wet the vehicle body; and then the second valve component on the corresponding detergent branch 21 can be adjusted to the open state through the switch component (according to the stains on the vehicle) to output the detergent corresponding to the stains, so that a variety of stains can be decomposed and cleaned.

[0045] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The scope of protection of the present application is not limited thereto. Although the present application has been described in detail with reference to the above-described embodiments, those skilled in the art should understand that any person skilled in the art can modify or easily conceive of changes to the technical solutions described in the above-described embodiments within the technical scope disclosed in the present application, or perform equivalent replacements for some of the technical features thereof. These modifications, changes, or replacements do not deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application shall be subject to the scope of protection of the claims.
