Description

Technical Field

[0001] This utility model relates to the field of vehicle decontamination technology, and in particular to a decontamination device for a vehicle's triangular window and a vehicle. Background Technology

[0002] The triangular window, a key component of vehicle body design, is typically located between the front door and the A-pillar or between the rear door and the C-pillar, balancing vehicle functionality and safety requirements. Initially, the triangular window primarily served to expand the driver's field of vision, effectively reducing blind spots caused by A-pillars and C-pillars, thereby improving driving safety. Subsequently, with the iterative upgrades in automotive technology, the function of the triangular window has continued to expand, playing a positive role not only in the stability of the vehicle body structure but also in optimizing interior lighting and ventilation.

[0003] Because the outer surface of the triangular window is constantly exposed to the external environment, it is easily contaminated by pollutants such as rainwater, mud, leaves, and dust. This can affect the driver's visibility through the triangular window, potentially leading to safety hazards while driving. Therefore, regular or frequent cleaning of the triangular window is necessary. However, current technology typically uses separate cleaning components and manual cleaning, resulting in low cleaning efficiency. Utility Model Content

[0074] To address the problem of low cleaning efficiency of vehicle triangular windows in existing technologies, this utility model provides a cleaning device for vehicle triangular windows and a vehicle.

[0075] Figure 1 This is a front view of the vehicle triangular window cleaning device provided in this embodiment of the utility model. Figure 2 This is a cross-sectional view of the vehicle triangular window cleaning device provided in this embodiment of the utility model, combined with... Figures 1 to 2 This utility model embodiment provides a cleaning device for a vehicle triangular window, comprising:

[0076] At least one nozzle structure 1 and at least one delivery channel 2;

[0077] It is understood that nozzle structure 1 and conveying channel 2 are connected, and the number of nozzle structures 1 and conveying channels 2 can be the same or different. When the number of nozzle structures 1 and conveying channels 2 is the same, one nozzle structure 1 is connected to one conveying channel 2; when the number of nozzle structures 1 and conveying channels 2 is different, one nozzle structure 1 is connected to two or more conveying channels 2, or one conveying channel 2 is connected to two or more nozzle structures 1.

[0078] The connectivity between nozzle structure 1 and conveying channel 2 is controllable. This can be achieved by installing a controllable switch, such as a solenoid valve, between them to regulate the connection. Connecting one nozzle structure 1 to one conveying channel 2 allows for targeted control of this connectivity. Connecting one nozzle structure 1 to two or more conveying channels 2, or vice versa, simplifies the structure of the cleaning device for the vehicle's triangular window.

[0079] In this embodiment of the utility model, a nozzle structure 1 connected to a conveying channel 2 is used as an example for explanation.

[0080] The nozzle structure 1 includes a gradually expanding cavity 11. The first end of the gradually expanding cavity 11 is connected to the conveying channel 2. The conveying channel 2 is used to input cleaning medium into the gradually expanding cavity 11 through the first end of the gradually expanding cavity 11. The second end of the gradually expanding cavity 11 is the outlet end of the cleaning medium. The diameter of the first end of the gradually expanding cavity 11 is smaller than the diameter of the second end of the gradually expanding cavity 11.

[0081] It should be noted that the gradually expanding cavity 11 is a cavity structure, and the gradually expanding cavity 11 is a flat cavity. The gradually expanding cavity 11 includes a first end and a second end opposite to each other, and the diameter of the cavity of the gradually expanding cavity 11 gradually increases from the first end 111 to the second end 112 of the gradually expanding cavity (i.e., in the direction of top view).

[0082] By designing the expanding cavity 11 as a flat chamber, and with the diameter of the chamber gradually increasing from the first end 111 to the second end 112, the surface-shaped cleaning medium sprayed within the expanding cavity can increase the cleaning area and improve the cleaning efficiency. The cleaning medium can be a liquid medium, a gaseous medium, or a combination of both. When the cleaning medium is liquid, it can be water or a liquid containing chemical substances that remove stains, bacteria, or viruses. When spraying the cleaning medium, it can be a surface-shaped gas, a surface-shaped fluid, or a surface-shaped air curtain.

[0083] The cleaning device for the triangular window of the vehicle may also include a media storage structure or a media supply structure. The media storage structure or media supply structure is used to store cleaning media. The media storage structure or media supply structure is connected to the conveying channel 2. The media storage structure or media supply structure is used to supply cleaning media to the conveying channel 2, so that the conveying channel 2 inputs cleaning media into the gradually expanding cavity 11 through the first end 111 of the gradually expanding cavity.

[0084] The cleaning medium is conveyed through the conveying channel 2 toward the first end 111 of the gradually expanding cavity. After entering the gradually expanding cavity 11, the cleaning medium flows to the second end 112 of the gradually expanding cavity and is ejected from the second end 112. The schematic diagram of the nozzle structure 1 and the conveying channel 2 is shown below. Figure 3 As shown, Figure 3 The direction indicated by the middle arrow is the direction in which the cleaning medium flows within the conveying channel 2 and the gradually expanding cavity 11, as well as the direction in which it is ejected from the ejection end.

[0085] It should also be noted that a switch structure can be provided within the expanding cavity 11. This switch structure can be a controllable retractable baffle. In the extended state, the baffle is completely in contact with the inner wall of the expanding cavity. This switch structure controls whether the cleaning medium can enter the expanding cavity 11 or whether it can be ejected from the ejection end of the expanding cavity 11. For example, the baffle is located at the first end 111 of the expanding cavity. In the extended state, the cleaning medium cannot enter the expanding cavity 11. In the retracted state, the cleaning medium can enter the expanding cavity 11 through the first end 111 and can also be ejected from the ejection end of the expanding cavity 11. Alternatively, the baffle can be located at the second end 112 of the expanding cavity, or between the first end 111 and the second end 112 of the expanding cavity. In the extended state, the cleaning medium can enter the expanding cavity 11 but cannot be ejected from the expanding cavity 11. When the baffle is retracted, the cleaning medium can enter the gradually expanding cavity 11 through the first end of the gradually expanding cavity 11, and can also be ejected from the ejection end of the gradually expanding cavity 11. For example, there are two baffles, which are respectively set at the first end 111 and the second end 112 of the gradually expanding cavity. The extension and retraction of the baffle at the first end 111 controls whether the cleaning medium can enter the gradually expanding cavity 11 through the first end 111, and the extension and retraction of the baffle at the second end 112 controls whether the cleaning medium can be ejected from the ejection end of the gradually expanding cavity 11.

[0086] By setting this switch structure, it is possible to control whether the nozzle structure 1 receives or sprays the cleaning medium, which facilitates the cleaning operation.

[0087] It should also be noted that this switch structure can also be used in conjunction with the aforementioned controllable switch, that is, to control whether the cleaning medium flows in the delivery channel 2 and the gradually expanding cavity 11 respectively.

[0088] The ejector end is located at the edge of the vehicle's triangular window 3. The nozzle of the ejector end that sprays the cleaning medium is flat, and the extension line of the direction in which the cleaning medium is sprayed is parallel or nearly parallel to the surface of the vehicle's triangular window. The cleaning medium, in a planar form, is sprayed from the ejector end to clean the surface of the vehicle's triangular window. That is, in a top-view direction, the diameter of the cavity within the expanding chamber 11 gradually increases.

[0089] By designing the expanding cavity 11 as a flat chamber, and gradually increasing the diameter of the cavity structure from the first end 111 to the second end 112 of the expanding cavity, the surface cleaning medium sprayed from the expanding cavity can increase the cleaning area and improve the cleaning efficiency.

[0090] It should be noted that "the nozzle is located at the edge of the vehicle's triangular window 3" can be understood as the nozzle being installed on the vehicle's triangular window 3, and the installation position is located at the edge of the vehicle's triangular window 3. It should also be noted that the vehicle's triangular window 3 is surrounded by a frame, which includes an upper frame 4, a lower frame 5, and a side frame 6. The upper frame 4 can be either the vehicle's A-pillar or C-pillar. "The nozzle is located at the edge of the vehicle's triangular window 3" can also be understood as the nozzle being installed on the frame, and the installation position is located at the edge of the frame. Since the edge of the frame fits against the edge of the vehicle's triangular window 3, it is considered that the installation position of the nozzle is located at the edge of the vehicle's triangular window 3.

[0091] The edge of the vehicle triangular window 3 includes at least one curved segment 7 and at least one straight segment 8;

[0092] It is understood that the edge of the vehicle triangular window 3 can be divided into at least one curved segment 7 and at least one straight segment 8. The length of each curved segment 7 can be the same or different. The specific value of the length of the curved segment 7 is not limited in this embodiment of the present invention. The length of each straight segment 8 can be the same or different. The specific value of the length of the straight segment 8 is not limited in this embodiment of the present invention.

[0093] The location of the ejection end includes at least one of the following:

[0094] Set along the curve segment 7;

[0095] Set along the straight line segment 8;

[0096] It is positioned at the corner where the curve segment 7 and the straight line segment 8 intersect;

[0097] The corner where the curve segment 7 intersects with another curve segment 7 is located; wherein, the corner where the curve segment 7 intersects with another curve segment 7 refers to the corner where one curve segment 7 intersects with another curve segment 7, that is, the corner where the curve segment 7 intersects with another curve segment 7 is located at the corner where the edge of the vehicle triangular window 3 includes at least two curve segments 7, and the first curve segment is one of the at least two curve segments, and the second curve segment is one of the at least two curve segments other than the first curve segment;

[0098] The corner where the line segment 8 intersects with another line segment 8 is located; wherein, the corner where the line segment 8 intersects with another line segment 8 refers to the corner where one line segment 8 intersects with another line segment 8, that is, the corner where the line segment 8 intersects with another line segment 8 is located when the edge of the vehicle triangular window 3 includes at least two line segments 8, and the first line segment is one of the at least two line segments, and the second line segment is one of the at least two line segments other than the first line segment;

[0099] The arrangement of the nozzle along curve segment 7 can be understood as the nozzle being aligned with curve segment 7, and the length of the nozzle being the same as or substantially the same as the length of curve segment 7. The arrangement of the nozzle along straight segment 8 can also be understood as the nozzle being aligned with straight segment 8, and the length of the nozzle being the same as or substantially the same as the length of straight segment 8. The nozzle being positioned at the corner where curve segment 7 and straight segment 8 intersect can be understood as the intersection of curve segment 7 and straight segment 8, with the intersection being a bend in the line segment. The nozzle is also bend-shaped, with a portion of the nozzle aligned with a portion of curve segment 7, and the length of that portion being the same as or substantially the same as the length of that portion of curve segment 7. The other portion of the nozzle is aligned with a portion of straight segment 8, and the length of that other portion being the same as or substantially the same as the length of that portion of straight segment 8. The nozzle is positioned at the corner where the curve segments intersect. This can be understood as one curve segment 7 intersecting with another curve segment 7. The intersection includes a part of one curve segment 7 and a part of another curve segment 7, and the intersection is a bend in the line segment. The nozzle is also bend in the line segment. A part of the nozzle is attached to a part of one curve segment 7, and the length of the part of the nozzle is the same as or substantially the same as the length of a part of one curve segment 7. The other part of the nozzle is attached to a part of another curve segment 7, and the length of the other part of the nozzle is the same as or substantially the same as the length of a part of another curve segment 7. The nozzle is positioned at the corner where the two straight segments 8 intersect. This can be understood as the intersection of one straight segment 8 and another straight segment 8. The intersection includes a part of one straight segment 8 and a part of another straight segment 8, and the intersection is a bend in the line segment. The nozzle is also bend in the line segment. A part of the nozzle is attached to a part of one straight segment 8, and the length of the part of the nozzle is the same as or substantially the same as the length of a part of one straight segment 8. The other part of the nozzle is attached to a part of another straight segment 8, and the length of the other part of the nozzle is the same as or substantially the same as the length of a part of another straight segment 8.

[0100] Since the cleaning device for the vehicle triangular window provided in this embodiment includes at least one nozzle structure 1, and each nozzle structure 1 includes a spray end, the number of spray ends is at least one. When the number of nozzle structures 1 is one, the spray end can be positioned at any of the above-described locations. For example, a schematic diagram showing a spray end positioned along a curved segment above the outer surface of the vehicle triangular window 3 is shown below. Figure 1 As shown in the diagram, a spray nozzle is positioned along a straight line segment below the outer surface of the vehicle's triangular window 3. Figure 4 As shown. When the number of nozzle structures 1 is two, as... Figure 5As shown, one of the spray nozzles is positioned along a straight segment below the outer surface of the vehicle's triangular window 3, while the other spray nozzle is positioned at the corner where the curved segment and the straight segment intersect at the edge of the vehicle's triangular window 3. When the spray nozzle is positioned below the edge of the vehicle's triangular window 3, the cross-sectional view of the vehicle's triangular window cleaning device is as follows. Figure 6 As shown.

[0101] It should be noted that the location of the ejector end provided in this embodiment includes the above-mentioned content, that is, the ejector end can be flexibly set at any position on the edge of the vehicle triangular window 3.

[0102] By setting two or more nozzle structures 1, the cleaning efficiency of the outer surface of the vehicle triangular window 3 can be improved.

[0103] It should be noted that the specific size of each nozzle can be determined based on its location and the dimensions of the outer surface of the vehicle's triangular window 3. For example, if the nozzle is positioned above or below the outer surface of the vehicle's triangular window 3, its size can be set to a larger size; if it is positioned to the left or right of the outer surface of the vehicle's triangular window 3, its size can be set to a smaller size. The larger the outer surface of the vehicle's triangular window 3, the larger the size of the nozzle; the greater the distance between the edges of the outer surface of the vehicle's triangular window 3, the larger the size of the nozzle. Here, the size of the nozzle can be understood as the end face size of the nozzle.

[0104] Among them, the top, bottom, left and right sides of the outer surface of the vehicle triangular window 3 are the observer's viewing angle directions when the observer faces the outer surface of the vehicle triangular window 3 while the vehicle is in a natural driving or parking state.

[0105] To improve the cleaning efficiency of the outer surface of the vehicle's triangular window 3 and to conserve cleaning media, the extension line of the direction of the cleaning media sprayed from the nozzle is made parallel or nearly parallel to the outer surface of the vehicle's triangular window 3. This allows the sprayed cleaning media to better adhere to or flow along the outer surface of the vehicle's triangular window 3 in a planar or air curtain manner, ensuring that the cleaning media is not wasted or lost. In other words, all the sprayed cleaning media can clean the outer surface of the vehicle's triangular window 3. Furthermore, cleaning the outer surface of the vehicle's triangular window 3 in a planar or air curtain manner can also increase the cleaning area and improve the cleaning efficiency.

[0106] Furthermore, the cleaning medium includes a gaseous medium and / or a liquid medium. In the process of cleaning the outer surface of the vehicle's triangular window 3, in one optional method, a surface-like or curtain-like gaseous medium can be sprayed, allowing the gaseous medium to adhere to or flow along the outer surface of the vehicle's triangular window 3, thereby achieving efficient cleaning while saving liquid medium. In another optional method, for some stubborn stains, the outer surface of the vehicle's triangular window 3 can be initially cleaned by spraying a surface-like liquid medium, followed by spraying a surface-like or curtain-like gaseous medium for further cleaning. After initial cleaning, any remaining stains are removed again to ensure effective removal of even the most stubborn stains. Alternatively, for some difficult-to-remove stains, a gas-liquid mixed-phase cleaning medium can be sprayed. This involves first introducing a liquid medium into the expanding chamber, followed by a gas medium into the expanding chamber of the nozzle structure. The gas medium disperses the liquid medium within the expanding chamber, forming a gas-liquid mixed-phase cleaning medium. This mixed-phase cleaning medium is then sprayed from the nozzle end. This mixed-phase cleaning medium has stronger cleaning power and is more suitable for removing stubborn stains with strong adhesion. The extension line of the direction in which the cleaning medium is sprayed from the nozzle end is nearly parallel to the outer surface of the vehicle's triangular window 3. This can be understood as forming an angle between the extension line of the direction in which the cleaning medium is sprayed from the nozzle end and the outer surface of the vehicle's triangular window 3, with the angle ranging from 0° to 5°.

[0107] In addition, the nozzle is designed to face the outer surface of the vehicle's triangular window 3.

[0108] The fact that the nozzle is positioned toward the outer surface of the vehicle's triangular window 3 can be understood as the direction in which the cleaning medium is sprayed from the nozzle is from the edge of the outer surface of the vehicle's triangular window 3 toward the interior of the outer surface of the vehicle's triangular window 3.

[0109] It should also be noted that, regardless of the direction in which the nozzle is positioned on the outer surface edge of the vehicle's triangular window 3, the cleaning medium sprayed from the nozzle is directed towards the interior or center of the outer surface of the vehicle's triangular window 3.

[0110] In this embodiment of the invention, the conveying channel 2 inputs cleaning medium into the gradually expanding cavity 11 through the first end 111 of the gradually expanding cavity. The second end 112 of the gradually expanding cavity is the spraying end of the cleaning medium. The spraying end is set at the edge of the outer surface of the vehicle triangular window 3 and faces the outer surface of the vehicle triangular window 3. The cleaning medium sprayed through the spraying end is sprayed towards the outer surface of the vehicle triangular window 3, thereby cleaning the outer surface of the vehicle triangular window 3. It is only necessary to control whether the conveying channel 2 delivers cleaning medium into the gradually expanding cavity 11 or whether the spraying end sprays cleaning medium to control whether the outer surface of the vehicle triangular window 3 is cleaned. The control method and cleaning method are simple and easy to operate.

[0111] The cleaning medium, in a planar form, is sprayed out from the spray nozzle to clean the outer surface of the vehicle's triangular window 3.

[0112] In order to improve the cleaning efficiency of the outer surface of the vehicle's triangular window and ensure that the cleaning medium sprayed from the nozzle can flow along or adhere to the outer surface of the vehicle's triangular window 3, the cleaning medium sprayed from the nozzle is set to be a surface fluid, so that the cleaning medium flows along the outer surface of the vehicle's triangular window 3, thereby achieving the purpose of quickly removing stains, bacteria or viruses from the outer surface of the vehicle's triangular window 3 and ensuring the driver's clear driving vision. The stains may include the fingerprints of the driver and passengers, mud or rainwater, etc.

[0113] It is understood that, in the embodiments of this utility model, the planar cleaning medium includes planar fluid, curtain fluid, air curtain, and planar gas.

[0114] In one alternative implementation, such as Figure 2 and Figure 6 As shown, two opposing walls are provided, namely a first wall 9 and a second wall 10, which are spaced apart, i.e., a certain gap is left between them. A nozzle structure 1 and a delivery channel 2 are provided or formed within this gap. The first wall 9 is the wall away from the outer surface of the vehicle's triangular window 3, and the second wall 10 is the wall close to the outer surface of the vehicle's triangular window 3. In this implementation, by providing two opposing walls and setting the nozzle structure 1 and delivery channel 2 within the gap between them, it is convenient to adjust the spray angle of the cleaning medium and to design the shape of the spray nozzle.

[0115] In another alternative implementation, such as Figure 7 and Figure 8 As shown, only one wall surface, namely the first wall surface 9, can be set. The first wall surface 9 and the outer surface of the vehicle triangular window 3 are spaced apart. A certain gap is left between the first wall surface 9 and the outer surface of the vehicle triangular window 3. The nozzle structure 1 and the delivery channel 2 are set or formed in the gap. In this implementation, by setting only one wall surface and setting the nozzle structure 1 and the delivery channel 2 on the outer surface of the vehicle triangular window 3, the structure of the cleaning device for the vehicle triangular window can be simplified, and the cleaning medium sprayed from the spray end can be better adhered to or flow along the outer surface of the vehicle triangular window 3.

[0116] In some embodiments, in order to ensure that the cleaning medium ejected from the nozzle is a planar fluid, the nozzle outlet (or the end face from which the cleaning medium is ejected) of the nozzle has at least one of the following shapes:

[0117] Long strip;

[0118] Slit-like;

[0119] Slit-like;

[0120] linear;

[0121] fissure-like;

[0122] Elliptical slit shape;

[0123] Curved slit-like; and,

[0124] Wavy, slit-like.

[0125] By setting the nozzle outlet for spraying the cleaning medium to the shape described above, the nozzle structure is formed into a flat nozzle, ensuring that the sprayed cleaning medium adheres to or flows along the outer surface of the vehicle's triangular window in a planar or air curtain manner, thereby more effectively cleaning the outer surface of the vehicle's triangular window and improving cleaning efficiency.

[0126] Furthermore, by designing the gradually expanding cavity 11 as a flat chamber, with the first end 111 of the gradually expanding cavity facing the second end 112 of the gradually expanding cavity, the diameter of the chamber of the gradually expanding cavity 11 gradually increases. Combined with setting the end face of the nozzle that sprays the cleaning medium to the above shape, it can better ensure that the nozzle sprays a surface, curtain, or screen-like cleaning medium, increasing the cleaning area and improving the cleaning efficiency.

[0127] Among them, "elongated" refers to the nozzle of the spraying end that emits the cleaning medium forming a rectangular structure, the length-to-width ratio of which is greater than a first proportional value; "slit-shaped" refers to the nozzle of the spraying end that emits the cleaning medium forming a finer rectangular structure, the length-to-width ratio of which is greater than a second proportional value; "narrow slit" refers to the nozzle of the spraying end that emits the cleaning medium forming an extremely fine rectangular structure, the length-to-width ratio of which is greater than a third proportional value; and "linear" refers to the nozzle of the spraying end that emits the cleaning medium forming a rectangular structure that is substantially nearly linear, the length-to-width ratio of which is greater than a fourth proportional value. The third proportional value is greater than the second proportional value, the second proportional value is greater than the first proportional value, and the fourth proportional value is greater than the third proportional value. For example, the third proportional value is 50, the second proportional value is 20, the first proportional value is 10, and the fourth proportional value is 100.

[0128] A slit-like shape refers to the nozzle outlet from which the cleaning medium is ejected forming an irregular slit shape, similar to a slit formed by tearing. The ratio of the length to the width of the circumscribed rectangle of the nozzle outlet is greater than the fifth ratio value, for example, the fifth ratio value is 30.

[0129] "Elliptical slit shape" refers to the nozzle of the spraying end that sprays out the cleaning medium in a finer elliptical shape, with the eccentricity of the ellipse being greater than a second preset value. For example, the second preset value can be 0.9.

[0130] The term "curved slit shape" refers to the shape of the nozzle from which the cleaning medium is ejected. The overall shape of the nozzle nozzle is curved, and the ratio of the length to the width of the circumscribed rectangle of the nozzle nozzle is greater than a second ratio value. For example, the second ratio value is 20.

[0131] The term "wavy slit shape" refers to the shape of the nozzle from which the cleaning medium is ejected. The overall shape of the nozzle nozzle is wavy, and the ratio of the length to the width of the circumscribed rectangle of the nozzle nozzle is greater than a second ratio value. For example, the second ratio value is 20.

[0132] By setting the first, second, third, and fourth proportional values ​​mentioned above, the ratio between the length and width of the nozzle can be adjusted, which means that the thickness and width of the surface or air curtain cleaning medium sprayed from the nozzle can be adjusted.

[0133] It should also be noted that, since the cleaning device for the vehicle's triangular window includes at least one nozzle structure 1, that is, at least one spray end, when there are two or more nozzle structures 1, the shapes of the nozzle outlets from which the cleaning medium is sprayed from the two or more nozzle structures 1 can be the same or different. For example, when there are three nozzle structures 1, the nozzle outlet of the spray end of each nozzle structure 1 can be either elongated or slit-shaped. For another example, when there are three nozzle structures 1, the nozzle outlet of one nozzle structure 1 is elongated, the nozzle outlet of another nozzle structure 1 is slit-shaped, and the nozzle outlet of the remaining nozzle structure 1 is a curved slit-shaped.

[0134] Since the nozzle may be located at the corner where two line segments intersect, in this case, the nozzle is angled. The end face of the nozzle from which the cleaning medium is ejected is divided into two parts at the angle, each part having the shape described above. Alternatively, it can be understood that when the nozzle is straightened, the end face of the nozzle has the shape described above.

[0135] Figure 9 This is a schematic diagram of the ejector end provided in an embodiment of the present invention, as shown below. Figure 9 As shown, in some embodiments, the ejection end includes at least two ejection outlets 1121, which are spaced apart in the extending direction of the ejection end.

[0136] In order to further reduce the cleaning time and improve the cleaning efficiency of removing stains from the vehicle's triangular window, in this embodiment, at least two spray outlets 1121 are opened on the spray end, and the cleaning medium is sprayed out simultaneously through at least two spray outlets 1121 to improve the cleaning efficiency of removing stains from the vehicle's triangular window.

[0137] Among them, "at least two nozzles 1121" refers to two, three or more nozzles 1121.

[0138] At least two nozzles 1121 are spaced apart in the extension direction of the nozzle end. This can be understood as a gap between any two adjacent nozzles 1121 in the extension direction of the nozzle end. The gap between any two adjacent nozzles 1121 can be the same or different.

[0139] It should also be noted that the shape of each of the at least two nozzles 1121 is one of the above-mentioned elongated, slit, narrow, linear, fissure, elliptical slit, curved slit, and wavy slit shapes, and the shapes of the at least two nozzles 1121 may be the same or different.

[0140] For example, such as Figure 9 As shown, six nozzles 1121 are provided on the nozzle end. The interval between any two adjacent nozzles 1121 is different, and the six nozzles 1121 have the same shape, which is long strip.

[0141] For example, six nozzles 1121 are opened on the nozzle end, wherein the interval between any two adjacent nozzles 1121 is the same, and among the six nozzles 1121, two are elongated, two are wavy slits, and two are curved slits.

[0142] For example, six nozzles 1121 are opened on the nozzle end. The interval between any two adjacent nozzles 1121 is different. Among the six nozzles 1121, two are long strips, three are lines, and one is a curved slit.

[0143] In some embodiments, when the ejection end is arranged along the curve segment 7, the nozzle structure 1 is curved, and the difference between the curvature of the nozzle structure 1 and the curvature of the curve segment 7 is less than a first preset curvature value.

[0144] The term "curved" in "nozzle structure 1" can be understood as meaning that the overall shape of nozzle structure 1 is curved or arc-shaped.

[0145] When the nozzle end is set along the curve segment 7, the nozzle structure 1 to which the nozzle end belongs is curved, and the difference between the curvature of the nozzle structure 1 to which the nozzle end belongs and the curvature of the corresponding curve segment 7 is less than the first preset curvature value. That is, the curvature of the nozzle structure 1 is basically consistent with the curvature of the corresponding curve segment 7, so as to ensure that the cleaning medium sprayed from the nozzle end of the nozzle structure 1 can better conform to the outer surface of the vehicle triangular window 3 and flow, thereby achieving the purpose of quickly removing stains from the outer surface of the vehicle triangular window 3.

[0146] For example, such as Figure 1As shown, when the nozzle end is located to the left or right of the outer surface of the vehicle's triangular window 3, the nozzle end is set along the curved segment 7, and the overall shape of the nozzle structure 1 is arc-shaped or curved.

[0147] When the ejection end is arranged along the straight segment 8, the nozzle structure 1 is linear;

[0148] The term "nozzle structure 1 is linear" can be understood as the overall shape of nozzle structure 1 being linear.

[0149] When the spray end is set along the straight segment 8, the nozzle structure 1 to which the spray end belongs is straight, so as to ensure that the cleaning medium sprayed from the spray end of the nozzle structure 1 can better adhere to the outer surface of the vehicle triangular window 3 and flow, thereby achieving the purpose of quickly removing stains from the outer surface of the door handle vehicle triangular window 3.

[0150] In some embodiments, when the ejection end is located at the corner where the curved segment 7 and the straight segment 8 intersect, the first part of the nozzle structure 1 is curved, the first part of the nozzle structure 1 is arranged along the first part of the curved segment 7, and the difference between the curvature of the first part of the nozzle structure 1 and the curvature of the first part of the curved segment 7 is less than a second preset curvature value. The second part of the nozzle structure 1 is straight, the second part of the nozzle structure 1 is arranged along the first part of the straight segment 8, wherein the first part of the nozzle structure 1 intersects with the second part of the nozzle structure 1, and the first part of the curved segment 7 intersects with the first part of the straight segment 8.

[0151] The first part of the nozzle structure 1 is curved, which can be understood as the entire first part of the nozzle structure 1 being curved or arc-shaped. The second part of the nozzle structure 1 is straight, which can be understood as the entire second part of the nozzle structure 1 being straight.

[0152] That is, the first part on the curve segment 7 intersects with the first part on the straight segment, forming an angled structure. The first part of the nozzle structure 1 and the second part of the nozzle structure 1 intersect, forming an angled shape. The difference between the curvature of the first part of the nozzle structure 1 to which the spray end belongs and the curvature of the first part on the corresponding curve segment 7 is less than the second preset curvature value. That is, it ensures that the curvature of the nozzle structure 1 is basically consistent with the curvature of the corresponding curve segment 7. In addition, the second part of the nozzle structure 1 is straight, which can ensure that the cleaning medium sprayed from the spray end of the nozzle structure 1 can better conform to the outer surface of the vehicle triangular window 3 and flow, thereby achieving the purpose of quickly removing stains from the outer surface of the vehicle triangular window 3.

[0153] In some embodiments, when the ejection end is located at the corner where the curve segment 7 intersects with the curve segment 7, the first part of the nozzle structure 1 is curved, the first part of the nozzle structure 1 is arranged along the first part of the curve segment 7, and the difference between the curvature of the first part of the nozzle structure 1 and the curvature of the first part of the curve segment 7 is less than a third preset curvature value. The second part of the nozzle structure 1 is curved, the second part of the nozzle structure 1 is arranged along the second part of the curve segment 7, and the difference between the curvature of the second part of the nozzle structure 1 and the curvature of the second part of the curve segment 7 is less than a fourth preset curvature value. In this embodiment, the first part of the nozzle structure 1 intersects with the second part of the nozzle structure 1, and the first part of the curve segment 7 intersects with the second part of the curve segment 7.

[0154] Wherein, the corner position where the curve segment 7 intersects with the curve segment refers to the corner position where one curve segment 7 (i.e., the first curve segment mentioned above) intersects with another curve segment 7 (i.e., the second curve segment mentioned above). The first part of the curve segment 7 is a part of one curve segment 7, and the second part of the curve segment 7 is a part of another curve segment 7. The intersection of the first part of the curve segment 7 and the second part of the curve segment means that a part of one curve segment 7 intersects with a part of another curve segment 7.

[0155] A portion of curve segment 7 intersects with a portion of another curve segment 7, forming a bend. The first part of nozzle structure 1 and the second part of nozzle structure 1 intersect, forming a bend. The difference between the curvature of the first part of nozzle structure 1 at the spray end and the curvature of the first part of the corresponding curve segment 7 is less than the third preset curvature value, ensuring that the curvature of nozzle structure 1 is basically consistent with the curvature of the corresponding curve segment 7. The difference between the curvature of the second part of nozzle structure 1 at the spray end and the curvature of the second part of the corresponding curve segment 7 is less than the fourth preset curvature value, ensuring that the curvature of nozzle structure 1 is basically consistent with the curvature of the corresponding curve segment 7. This ensures that the cleaning medium sprayed from the spray end of nozzle structure 1 can better adhere to the outer surface of the vehicle triangular window 3, thereby achieving the purpose of quickly removing stains from the outer surface of the vehicle triangular window 3.

[0156] In some embodiments, when the ejection end is located at the corner where the straight segment 8 intersects with the straight segment 8, the first part of the nozzle structure 1 is straight and is arranged along the first part of the straight segment 8, and the second part of the nozzle structure 1 is straight and is arranged along the second part of the straight segment, wherein the first part of the nozzle structure 1 intersects with the second part of the nozzle structure 1, and the first part of the straight segment 8 intersects with the second part of the straight segment 8.

[0157] Wherein, the corner position where the line segment 8 intersects with the line segment 8 refers to the corner position where one line segment 8 (i.e., the first line segment mentioned above) and another line segment 8 (i.e., the second line segment mentioned above) intersect. The first part of the line segment 8 is a part of one line segment 8, and the second part of the line segment 8 is a part of another line segment 8. The intersection of the first part of the line segment 8 and the second part of the line segment 8 means that a part of one line segment 8 intersects with a part of another line segment 8.

[0158] A portion of one straight segment 8 intersects with a portion of another straight segment 8, forming a bend. The first part of the nozzle structure 1 and the second part of the nozzle structure 1 intersect, forming a bend. The first part of the nozzle structure 1 to which the spray end belongs is straight, and the second part of the nozzle structure 1 to which the spray end belongs is straight. This ensures that the cleaning medium sprayed from the spray end of the nozzle structure 1 can better adhere to the outer surface of the vehicle triangular window 3 and flow, thereby achieving the purpose of quickly removing stains from the outer surface of the vehicle triangular window 3.

[0159] It should be noted that the first preset curvature value, the second preset curvature value, the third preset curvature value, and the fourth preset curvature value can be the same or different, but all of the above values ​​are relatively small.

[0160] In one optional implementation, the cleaning device for the vehicle triangular window includes two nozzle structures 1. One nozzle structure 1 is located below the outer surface of the vehicle triangular window 3. The overall shape of the nozzle structure 1 is straight, and the end face of the nozzle structure 1 that sprays the cleaning medium is elongated. The other nozzle structure 1 is located above the outer surface of the vehicle triangular window 3. The overall shape of the nozzle structure 1 is curved, and the end face of the nozzle structure 1 that sprays the cleaning medium is elongated.

[0161] In one optional implementation, the cleaning device for the vehicle triangular window includes two nozzle structures 1. One nozzle structure 1 is located below the outer surface of the vehicle triangular window 3. The overall shape of the nozzle structure 1 is straight, and the cleaning medium sprayed from the nozzle structure 1 is parallel to the outer surface of the vehicle triangular window 3. The other nozzle structure 1 is located above the outer surface of the vehicle triangular window 3. The overall shape of the nozzle structure 1 is curved, and the angle between the cleaning medium sprayed from the nozzle structure 1 and the outer surface of the vehicle triangular window 3 is 4°.

[0162] Figure 10 and Figure 11 This is a schematic diagram of the nozzle structure 1 provided by this utility model.

[0163] In some embodiments, a flow splitting structure is provided inside the gradually expanding cavity 11;

[0164] The diversion structure is perpendicular to or intersects with the first direction, which is the flow direction of the cleaning medium in the gradually expanding cavity 11.

[0165] The function of this diversion structure is to divert the cleaning medium in the expanding cavity 11 to ensure that the cleaning medium ejected through the ejection end is a surface fluid.

[0166] It should be noted that the direction of the flow-dividing structure is perpendicular to or intersects with the flow direction of the cleaning medium in the expanding cavity 11, and in order to ensure the flow-dividing effect of the cleaning medium, the flow-dividing structure is a fluid dispersion structure. Preferably, the plane of the flow-dividing plate is perpendicular to the flow direction of the cleaning medium in the expanding cavity.

[0167] In one alternative implementation, such as Figure 10 As shown, the diversion structure includes multiple diversion columns 113 arranged at intervals; wherein, the number of diversion columns 113 can be determined according to the size of the expanding cavity 11, that is, the larger the size of the expanding cavity 11, the more diversion columns 113 there are.

[0168] A diversion channel is formed between two adjacent diversion columns 113, and the cleaning medium is diverted to the ejection end through the diversion channel.

[0169] The size of the diversion channel can be determined based on the size of the expanding cavity 11 and the number of diversion columns 113.

[0170] The cleaning medium is diverted through the diversion channel to the ejection end.

[0171] Preferably, the dimensions of the diversion channels formed between any two adjacent diversion columns 113 are as equal as possible to ensure uniform diversion of the cleaning medium.

[0172] In this configuration, the first end 1131 of each diversion column extends into the interior of the diffuser 11, and the second end 1132 of the diversion column extends to the end face near the ejection end, so that the output end of the diversion channel can be as close as possible to or flush with the end face of the ejection end. The extension direction of each diversion column 113 is perpendicular to or intersects with the flow direction of the cleaning medium in the diffuser 11. Preferably, the extension direction of each diversion column 113 is perpendicular to the flow direction of the cleaning medium in the diffuser 11. The extension of the second end 1132 of the diversion column to the end face near the ejection end can be understood as the distance between the second end 1132 of the diversion column and the end face of the ejection end being less than a preset distance, for example, 5 mm.

[0173] After the cleaning medium enters the gradually expanding cavity 11 through the first end 111 of the gradually expanding cavity, the cleaning medium enters the diversion channel and flows to the ejection end through the diversion channel.

[0174] By setting a diversion column 113 in the gradually expanding cavity 11, and dividing the diversion channel by the diversion column 113, the cleaning medium in the gradually expanding cavity 11 can be uniformly diverted, ensuring that the cleaning medium sprayed from the spray end is a surface fluid that can adhere to or flow along the outer surface of the vehicle triangular window 3. Figure 10 The arrow shown indicates the flow direction of the cleaning medium.

[0175] In this optional implementation, multiple diverter columns 113 can be connected to form a fixed, integrated structure. In this case, the two outermost diverter columns 113 can be fixed within the expanding cavity 11, thus achieving the installation of multiple diverter columns 113. Furthermore, the diverter columns 113 can be detachably installed within the expanding cavity 11. This installation method is simple and facilitates adjustment of the size of the diversion channel formed between any two adjacent diverter columns. Alternatively, instead of connecting the multiple diverter columns 113, each diverter column 113 can be installed individually within the expanding cavity 11. This installation method allows for individual replacement of each damaged diverter column, saving tooling materials.

[0176] Furthermore, a flow-diverting channel is formed between the first flow-diverting column and the corresponding side wall of the gradually expanding cavity; wherein, the first flow-diverting column is the flow-diverting column 113 located at the edge among a plurality of spaced-apart flow-diverting columns 113.

[0177] In the case that the first diversion column 113 located at the edge of the multiple spaced diversion columns 113 does not fit against the side wall of the expansion cavity, the gap between the first diversion column and the side wall of its corresponding expansion cavity also forms a diversion channel, which is used to divert the cleaning medium.

[0178] The side wall of the gradually expanding cavity corresponding to the first diverter column can be understood as the first diverter column being set close to a certain part of the inner wall of the gradually expanding cavity. This part is located between the top wall and the bottom wall of the gradually expanding cavity, and this part is the side wall of the gradually expanding cavity corresponding to the first diverter column.

[0179] It should be noted that since the expanding cavity is a flat chamber, a row of spaced-apart diversion columns 113 is provided, so there are two first diversion columns. The two first diversion columns are arranged opposite each other, and the side walls of the expanding cavity corresponding to the two first diversion columns are also opposite each other.

[0180] Optionally, the diversion column 113 can be made of rubber or stainless steel to prevent it from rusting in an environment where the cleaning medium is wet, thereby improving its service life.

[0181] In one alternative implementation, such as Figure 11 As shown, the diversion structure includes multiple diversion pipes 114; the number of diversion pipes 114 can be determined according to the size of the expanding cavity 11, that is, the larger the size of the expanding cavity 11, the more diversion pipes 114 there are.

[0182] The first end 1141 of the diversion pipe extends into the interior of the gradually expanding cavity 11, and the second end 1142 of the diversion pipe extends into the ejection end; the cleaning medium enters the diversion pipe from the first end 1141 and is diverted from the second end 1142 to the ejection end.

[0183] The extension of the second end 1142 of the diversion pipe to the ejection end can be understood as the second end 1142 of the diversion pipe being close to the end face of the ejection end, but not extending beyond the end face of the ejection end. The distance between the second end 1142 of the diversion pipe and the end face of the ejection end is less than a preset distance, for example, the preset distance is 5mm.

[0184] It is understood that in this implementation, at the first end 1141 of the diversion pipe in the expanding cavity 11, all structures except the first end 1141 of the diversion pipe are closed or sealed structures, that is, the cleaning medium can only enter the first end 1141 of the diversion pipe and enter the interior of the diversion pipe 114 from the first end 1141 of the diversion pipe. The sealing structure can be a solid sealing structure, where a portion of the gradually expanding cavity 11 is designed as a sealed solid, extending to the ejection end. Multiple diversion pipes 114 are opened inside the sealed solid, connecting the non-sealed portion of the gradually expanding cavity 11 to the ejection end. This allows the cleaning medium in the gradually expanding cavity 11 to enter the diversion pipe 114 through the first end 1141 and then be diverted to the ejection end from the second end 1142. Alternatively, the sealing structure can be a sealing plate that fits tightly against the inner wall of the gradually expanding cavity 11. The first end 1141 of the diversion pipe passes through the sealing plate, and the second end 1142 extends to the ejection end. This allows the cleaning medium in the gradually expanding cavity 11 to enter the diversion pipe 114 through the first end 1141 and then be diverted to the ejection end from the second end 1142.

[0185] After the cleaning medium enters the gradually expanding cavity 11 through the first end 111 of the gradually expanding cavity, the cleaning medium gradually flows to the first end 1141 of the diversion pipe and then enters the diversion pipe 114, and flows to the ejection end through the second end 1142 of the diversion pipe.

[0186] By setting a diversion pipe 114 in the expansion cavity 11, the cleaning medium in the expansion cavity 11 can be uniformly diverted, ensuring that the cleaning medium sprayed from the spray end is a surface fluid that can adhere to or flow along the outer surface of the vehicle triangular window 3. Figure 11 The arrow shown indicates the flow direction of the cleaning medium.

[0187] Preferably, the diameters of the multiple branch pipes 114 are the same to ensure uniform distribution of the cleaning medium. The specific value of the diameter of the branch pipe 114 can be determined according to the size of the expanding cavity 11, that is, the larger the size of the expanding cavity 11, the larger the diameter of the branch pipe 114.

[0188] In this optional implementation, multiple branch lines 114 can be connected to form a fixed, integrated structure. In this case, any one or two branch lines 114 can be connected to the inside of the expanding cavity 11 to achieve the installation of multiple branch lines 114. This installation method of the branch lines 114 is simple to operate. Alternatively, the multiple branch lines 114 can be installed separately in the expanding cavity 11 without connecting them. This installation method of the branch lines 114 facilitates individual replacement of each damaged branch line 114, saving tooling materials.

[0189] Optionally, the diversion pipe 114 can be made of rubber or stainless steel to prevent the cleaning medium from corroding the inner wall of the diversion pipe 114 and to improve the service life of the diversion pipe 114.

[0190] It should be noted that, since the expanding cavity is a flat chamber, a row of branch pipes 114 is installed.

[0191] In one optional implementation, the flow splitting structure includes a flow splitting plate; the flow splitting plate is disposed perpendicular to the top wall and the bottom wall of the gradually expanding cavity 11, and the flow splitting plate intersects with or is perpendicular to the first direction.

[0192] The fact that the flow divider is set perpendicular to the top wall and bottom wall of the expanding cavity 11 can be understood as the top wall and bottom wall of the expanding cavity 11 being two opposite and parallel walls in the expanding cavity 11, and the plane on which the flow divider is set is perpendicular to the plane containing the top wall and bottom wall of the expanding cavity 11.

[0193] In addition, in order to ensure that the flow divider can divert the cleaning medium in the expansion cavity 11, the plane of the flow divider is perpendicular to or intersects with the flow direction of the cleaning medium in the expansion cavity. Preferably, the plane of the flow divider is perpendicular to the flow direction of the cleaning medium in the expansion cavity.

[0194] In this optional implementation, the edge of the diverter plate is sealed and fitted to the inner wall of the diffuser 11, and the cleaning medium in the diffuser 11 can only be diverted to the ejection end through the through hole.

[0195] The number of through holes on the manifold can be determined based on the size of the manifold or the size of the expanding cavity 11. That is, the larger the size of the manifold or the size of the expanding cavity 11, the more through holes can be opened on the manifold.

[0196] After the cleaning medium enters the gradually expanding cavity 11 through the first end 111 of the gradually expanding cavity, the cleaning medium is diverted through the through holes on the diverter plate and flows to the ejection end.

[0197] By setting a flow divider in the expansion cavity 11, the cleaning medium in the expansion cavity 11 can be uniformly distributed, ensuring that the cleaning medium sprayed from the nozzle can adhere to or flow along the outer surface of the vehicle triangular window 3.

[0198] Furthermore, in this optional implementation, the shape of the through hole is not limited to a circle; it can also be a rectangle, an ellipse, or other shapes.

[0199] Preferably, in order to ensure uniform distribution of the cleaning medium, the size and shape of the multiple through holes are equal.

[0200] Alternatively, the diverter plate can be made of rubber or stainless steel to prevent it from rusting or corroding in environments where the cleaning medium is wet, thus extending its service life.

[0201] Furthermore, in the second direction, the diameter of the through hole gradually increases; wherein, the second direction is the direction in which the cleaning medium is ejected from the through hole.

[0202] By setting the orifice diameter to gradually increase in the direction of the sprayed cleaning medium, the cleaning medium after being diverted through different orifices can cross after being sprayed, thereby ensuring that the sprayed cleaning medium is in a planar shape.

[0203] It should also be noted that, since the vehicle triangular window cleaning device provided in this embodiment includes at least one nozzle structure 1, when the number of nozzle structures 1 is two or more, the diffuser 11 of each nozzle structure 1 can be implemented using one of the three implementation methods described above. That is, the diffuser 11 of each nozzle structure 1 has the same structure. For example, when there are two nozzle structures 1, both diffuser 11 of the two nozzle structures 1 are provided with a diversion pipe 114, or both diffuser 11 of the two nozzle structures 1 are provided with a diversion column. When the number of nozzle structures 1 is two or more, each nozzle structure 1... The diffuser 11 can be implemented using two or more of the three implementation methods described above. That is, the diffuser 11 of each nozzle structure 1 can be the same or different. For example, when there are three nozzle structures 1, one nozzle structure 1 has a flow divider column in its diffuser 11, another nozzle structure 1 has a flow divider pipe 114 in its diffuser 11, and the remaining nozzle structure 1 has a flow divider plate in its diffuser 11. Or, when there are three nozzle structures 1, two nozzle structures 1 have flow divider columns in their diffuser 11, and the other nozzle structure 1 has a flow divider pipe 114 in its diffuser 11.

[0204] In some embodiments, such as Figure 10 and Figure 11As shown, the expanding cavity 11 and the conveying channel 2 form an angle, the angle being between 45° and 90°.

[0205] By designing an angle between the expanding cavity 11 and the conveying channel 2, the cleaning medium can be slowed down when it flows through the bend where the conveying channel 2 connects to the expanding cavity 11, effectively reducing the pressure of the cleaning medium and ensuring that the surface fluid is ejected from the ejection end.

[0206] It is understood that the angle formed by the expanding cavity 11 and the conveying channel 2 is the angle between the first direction and the second direction. The first direction is the direction in which the conveying channel 2 conveys the cleaning medium to the first end 111 of the expanding cavity, and the second direction is the direction in which the cleaning medium is conveyed from the first end 111 of the expanding cavity and the edge of the first end 111 of the expanding cavity into the expanding cavity 11.

[0207] Preferably, the included angle is 90°, as this provides the best deceleration effect on the cleaning medium.

[0208] By designing the expanding cavity 11 as a flat chamber, with the first end 111 of the expanding cavity facing the second end 112 of the expanding cavity, the diameter of the expanding cavity 11 gradually increases. Combined with setting the end face of the nozzle that sprays the cleaning medium into the above-mentioned shape (including at least one of the following shapes: strip-shaped, slit-shaped, narrow slit-shaped, linear, fissure-shaped, elliptical slit-shaped, curved slit-shaped, and wavy slit-shaped), and designing the expanding cavity 11 to form an angle with the conveying channel 2, it is possible to better ensure that the nozzle sprays a surface-shaped, curtain-shaped, or screen-shaped cleaning medium, thereby increasing the cleaning area and improving the cleaning efficiency.

[0209] In one alternative implementation, the cross-section of the expanding cavity 11 is designed as a trapezoidal structure, the angle between the expanding cavity 11 and the conveying channel 2 is 90°, the end face of the nozzle from which the cleaning medium is ejected is slit-shaped, the conveying channel 2 inputs the cleaning medium into the expanding cavity 11 through the first end of the expanding cavity 11, the cleaning medium is decelerated at the bend where the conveying channel 2 connects with the expanding cavity 11, and then flows to the nozzle of the expanding cavity 11, where it is ejected as a surface fluid through the slit-shaped nozzle to clean the outer surface of the vehicle triangular window 3.

[0210] In some embodiments, the cleaning device for the vehicle triangular window further includes a pressurizing structure, which pressurizes the cleaning medium and then inputs the pressurized cleaning medium into the expanding cavity 11 through the delivery channel 2.

[0211] The pressurizing structure can be a high-pressure pump.

[0212] The pressurizing structure is used to pressurize the cleaning medium. After the cleaning medium is pressurized by the pressurizing structure, the pressurized cleaning medium (or high-pressure cleaning medium) is delivered to the first end of the gradually expanding cavity 11 through the delivery channel 2, so that the pressurized cleaning medium (or high-pressure cleaning medium) is input into the gradually expanding cavity through the delivery channel 2. The pressurized cleaning medium (or high-pressure cleaning medium) has a better decontamination effect.

[0213] In some embodiments, considering the low ambient temperature in winter or other low-temperature weather, in order to achieve rapid decontamination of the outer surface of the vehicle triangular window 3, a heating structure is provided in the expanding cavity 11 or the conveying channel 2. The heating structure is used to heat the cleaning medium so that the heated surface cleaning medium is sprayed out from the spraying end, thereby achieving efficient decontamination and rapid drying of the outer surface of the vehicle triangular window 3.

[0214] The heating structure can be a mesh resistance wire or other components with heating function, and the heating structure can also be connected to a control structure, which is used to control the heating structure to start or stop heating the cleaning medium.

[0215] Preferably, the heating structure can be located near the end face of the nozzle from which the cleaning medium is ejected, so as to ensure that the cleaning medium ejected from the nozzle has a sufficient temperature.

[0216] The following describes the specific structure of the cleaning device for the vehicle's triangular window using a complete implementation method:

[0217] The cleaning device for the vehicle's triangular window includes two nozzle structures 1, each connected to a conveying channel 2. One nozzle structure 1 has its ejection end positioned below the outer surface of the vehicle's triangular window 3. This nozzle structure 1 has a straight overall shape and an elongated nozzle outlet. The angle between the diffuser 11 of this nozzle structure 1 and the conveying channel 2 is 90°. The cleaning medium ejected from this nozzle structure 1 is parallel to the outer surface of the vehicle's triangular window 3. The other nozzle structure 1 has its ejection end positioned above the outer surface of the vehicle's triangular window 3. This nozzle structure 1 has a curved overall shape and a slit-like nozzle outlet. The angle between the diffuser 11 of this nozzle structure 1 and the conveying channel 2 is 90°. The angle between the cleaning medium ejected from this nozzle structure 1 and the outer surface of the vehicle's triangular window 3 is 4°. Both nozzle structures 1 have a diversion pipe 114 within their diffuser 11 to divert the cleaning medium.

[0218] This utility model embodiment also provides a vehicle, including a cleaning device for the vehicle triangular window as described in any of the preceding claims.

[0219] The vehicle provided in this embodiment can clean the surface of the triangular window using a cleaning device on the triangular window. The nozzle is positioned at the edge of the triangular window and faces its outer surface. Cleaning medium is sprayed from the nozzle to clean the outer surface of the triangular window. Cleaning is controlled by adjusting whether the delivery channel supplies cleaning medium into the expanding chamber or whether the nozzle sprays cleaning medium. The control and cleaning methods are simple and easy to operate. Specifically, the edge of the triangular window includes at least one curved segment and at least one straight segment; the nozzle… The setting position includes at least one of the following: set along the curved segment, set along the straight segment, set at the corner where the curved segment and the straight segment intersect, set at the corner where the curved segment and the straight segment intersect, set at the corner where the straight segment and the straight segment intersect. That is, the spray end can be set at any position or direction on the edge of the vehicle's triangular window, which facilitates the layout of the spray end. The extension line of the direction in which the cleaning medium is sprayed from the spray end is designed to be parallel or nearly parallel to the surface of the vehicle's triangular window. Moreover, the spray end of the gradually expanding cavity sprays a surface-shaped cleaning medium, which can increase the cleaning area of ​​the sprayed cleaning medium and improve the cleaning efficiency on the outer surface of the vehicle's triangular window.

[0220] It should be noted that the vehicle provided in this utility model embodiment is a vehicle that includes the cleaning device for the vehicle triangular window described in any of the above claims. Therefore, all embodiments of the cleaning device for the vehicle triangular window described above are applicable to this vehicle and can achieve the same or similar technical effects.

[0221] like Figure 12 As shown, this utility model embodiment also provides a method for cleaning a vehicle triangular window, applied to the cleaning device for a vehicle triangular window as described in any of the above claims, the method comprising:

[0222] Step 1201: Introduce the cleaning medium into the diffuser chamber of the nozzle structure through the delivery channel.

[0223] The nozzle structure and the conveying channel are connected, and the number of nozzle structures and the number of conveying channels can be the same or different. When the number of nozzle structures and the number of conveying channels are the same, one nozzle structure is connected to one conveying channel; when the number of nozzle structures and the number of conveying channels are different, one nozzle structure is connected to two or more conveying channels, or one conveying channel is connected to two or more nozzle structures.

[0224] The connectivity between the nozzle structure and the delivery channel is controllable. This can be achieved by installing a controllable switch, such as a solenoid valve, between them to regulate the connection. Connecting one nozzle structure to one delivery channel allows for targeted control of this connectivity. Connecting one nozzle structure to two or more delivery channels, or vice versa, simplifies the design of the cleaning device for the vehicle's triangular window.

[0225] The cleaning medium is delivered through the delivery channel toward the first end of the gradually expanding cavity, and after entering the gradually expanding cavity, it flows toward the second end of the gradually expanding cavity.

[0226] Step 1202: Spray the surface cleaning medium through the nozzle structure to clean the surface of the vehicle's triangular window.

[0227] The cleaning medium enters the gradually expanding cavity through the first end and flows to the second end, and is ejected from the second end.

[0228] A switch structure can also be installed inside the expanding cavity. This switch structure can be a baffle that can be controlled to extend and retract. In the extended state, the baffle is completely in contact with the inner wall of the expanding cavity. The switch structure controls whether the cleaning medium can enter the expanding cavity or whether it can be ejected from the ejection end of the expanding cavity.

[0229] By setting this switch structure, it is possible to control whether the nozzle structure receives or sprays the cleaning medium, which facilitates the control of the cleaning operation.

[0230] To improve the cleaning efficiency of the outer surface of the vehicle's triangular window and ensure that the cleaning medium sprayed from the nozzle flows along or adheres to the outer surface of the vehicle's triangular window, the cleaning medium sprayed from the nozzle is set to be a surface fluid. This allows the cleaning medium to flow along the outer surface of the vehicle's triangular window, thereby quickly removing stains, bacteria, or viruses from the outer surface of the vehicle's triangular window and ensuring the driver's clear vision. The stains may include fingerprints of the driver and passengers, mud, sand, or rainwater.

[0231] In some embodiments, the cleaning medium is introduced into the diffuser cavity of the nozzle structure through a delivery channel, including:

[0232] After the cleaning medium is pressurized by the pressurizing structure, the pressurized cleaning medium is input into the gradually expanding cavity through the conveying channel;

[0233] The pressurizing structure can be a high-pressure pump.

[0234] The pressurizing structure is used to pressurize the cleaning medium. After the cleaning medium is pressurized by the pressurizing structure, the pressurized cleaning medium (or high-pressure cleaning medium) is delivered to the first end of the gradually expanding cavity through the delivery channel, so that the delivery channel inputs the pressurized cleaning medium (or high-pressure cleaning medium) into the gradually expanding cavity.

[0235] Then, the pressurized cleaning medium, in a planar form, is sprayed out through the nozzle structure to clean the surface of the vehicle's triangular window.

[0236] By pressurizing the cleaning medium, the nozzle structure sprays out the pressurized cleaning medium in a planar shape. This pressurized cleaning medium (or high-pressure cleaning medium) has a better cleaning effect.

[0237] In some embodiments, the cleaning medium in a planar form is sprayed through the spray end of the nozzle structure to clean the surface of the vehicle's triangular window, including at least one of the following:

[0238] A planar liquid medium is sprayed from the nozzle end of the nozzle structure to clean the surface of the vehicle's triangular window.

[0239] A planar gaseous medium is ejected from the nozzle end of the nozzle structure to clean the surface of the vehicle's triangular window.

[0240] The nozzle structure sprays a surface-shaped gaseous medium and a surface-shaped liquid medium through its nozzle outlet end to clean the surface of the vehicle's triangular window. Specifically, when the cleaning medium includes a liquid medium and / or a gaseous medium, and the medium supply structure includes a liquid supply structure and / or a gas supply structure, three methods are provided for cleaning the surface of the vehicle's triangular window:

[0241] Implementation Method 1: A planar liquid medium is sprayed from the nozzle structure to clean the surface of the vehicle's triangular window. In this implementation method, the nozzle structure only sprays a liquid medium, and the surface of the vehicle's triangular window is cleaned solely through this planar liquid medium.

[0242] Method 2: A planar gaseous medium is ejected from the nozzle structure to clean the surface of the vehicle's triangular window. In this method, the nozzle structure only ejects a gaseous medium, and the surface of the vehicle's triangular window is cleaned solely through this planar gaseous medium.

[0243] It should be noted that stains with weak adhesion on the surface of the vehicle's triangular window can be removed using either the first or second method described above. For example, stains such as droplets or flower petals can be removed simply by spraying a surface-shaped gaseous medium through the nozzle structure.

[0244] Method 3: A planar gaseous medium and a planar liquid medium are ejected from the nozzle structure to clean the surface of the vehicle's triangular window. In other words, the surface of the vehicle's triangular window is cleaned by combining a gaseous medium with a liquid medium.

[0245] Optionally, in implementation method three, for stains with strong adhesion on the surface of the vehicle's triangular window, such as mud stains, the main cleaning method can be cleaning with a gaseous medium, and the auxiliary cleaning method can be cleaning with a liquid medium.

[0246] In some embodiments, the cleaning medium in a planar form is sprayed through the nozzle end of the nozzle structure to clean the surface of the vehicle's triangular window, including:

[0247] A surface-shaped cleaning medium with a first preset pressure is sprayed out through the nozzle structure to perform initial cleaning on the surface of the vehicle's triangular window.

[0248] A surface-shaped cleaning medium with a second preset pressure is sprayed out through the nozzle structure to perform secondary cleaning on the surface of the vehicle's triangular window.

[0249] Wherein, the first preset pressure is greater than the second preset pressure.

[0250] In this embodiment, cleaning the surface of the vehicle's triangular window can be divided into two or more stages. In the case of two stages, the first stage involves using a surface-type cleaning medium at a first preset pressure (a relatively high pressure value) to perform initial cleaning of the vehicle's triangular window surface, removing larger stains. The second stage involves using a surface-type cleaning medium at a second preset pressure (a relatively low pressure value) to perform secondary cleaning of the vehicle's triangular window surface, removing the remaining stains from the first stage. In the case of multiple stages, the pressure value of the cleaning medium can be further reduced based on the above two stages to perform the next stage of cleaning operation.

[0251] In some embodiments, the cleaning medium in a planar form is sprayed through the nozzle end of the nozzle structure to clean the surface of the vehicle's triangular window, including:

[0252] A surface-shaped cleaning medium with a first preset flow rate is sprayed out through the nozzle structure to perform initial cleaning on the surface of the vehicle's triangular window.

[0253] A surface-shaped cleaning medium with a second preset flow rate is sprayed out through the nozzle structure to perform secondary cleaning on the surface of the vehicle's triangular window.

[0254] Wherein, the first preset flow rate is greater than the second preset flow rate.

[0255] In this embodiment, the cleaning of the vehicle's triangular window surface can be divided into two or more stages. In the case of two stages, the first stage involves using a surface-type cleaning medium with a first preset flow rate (a relatively large flow rate value) to perform initial cleaning of the vehicle's triangular window surface, removing larger stains. The second stage involves using a surface-type cleaning medium with a second preset flow rate (a relatively small flow rate value) to perform secondary cleaning of the vehicle's triangular window surface, removing the remaining stains from the first stage. In the case of multiple stages, the flow rate of the cleaning medium can be further reduced based on the above two stages to perform the next stage of cleaning operation.

[0256] The above describes the preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this utility model, and these improvements and modifications are also within the protection scope of this utility model.
