[0076] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0077] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0078] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0079] In this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. "And / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0080] This disclosure provides an exemplary embodiment of a water spraying device, with reference to... Figures 1-20 As shown, the water spraying device may include a switching mechanism 40, a water pump 20, a first water spraying device 10, and a second water spraying device 30. The switching mechanism 40 has a main water inlet structure 411 and at least two water outlets 412, including a first water outlet 412a and a second water outlet 412b. The switching mechanism 40 is used to switch the main water inlet structure 411 to be connected to the first water outlet 412a or the second water outlet 412b. The water outlet of the water pump 20 is connected to the main water inlet structure 411. The first water spraying device 10 is connected to the first water outlet 412a. The second water spraying device 30 is connected to the second water outlet 412b.

[0081] The water spraying device disclosed herein has a switching mechanism 40 capable of switching the main water inlet structure 411 to connect to the first water outlet 412a, thereby enabling the water pump 20 to provide a water source for the first water spraying device 10; the switching mechanism 40 can also switch the main water inlet structure 411 to connect to the second water outlet 412b, thereby enabling the water pump 20 to provide a water source for the second water spraying device 30; thus enabling one water pump 20 to provide a water source for at least two water spraying devices, thereby saving the number of water pumps 20 used and reducing costs. The water pump 20 can be an electromechanical integrated electric water pump.

[0082] In some exemplary embodiments of this disclosure, reference is made to Figures 1-4 , Figures 6-16 As shown, the switching mechanism 40 has a main water inlet structure 411 and at least two water outlets 412, the at least two water outlets 412 including a first water outlet 412a and a second water outlet 412b; for example, the switching mechanism 40 may have a main water inlet structure 411 and two water outlets 412; the switching mechanism 40 may also have a main water inlet structure 411 and three or more water outlets 412. Generally, the number of water outlets 412 can be the same as the number of water spray devices that need to be connected.

[0083] The outlet of water pump 20 is connected to the main water inlet structure 411; the first water spray device 10 is connected to the first water outlet 412a; and the second water spray device 30 is connected to the second water outlet 412b. The switching mechanism 40 is used to switch the main water inlet structure 411 to either the first water outlet 412a or the second water outlet 412b; that is, the switching mechanism 40 can switch the main water inlet structure 411 to the first water outlet 412a, thereby enabling water pump 20 to provide water to the first water spray device 10; the switching mechanism 40 can also switch the main water inlet structure 411 to the second water outlet 412b, thereby enabling water pump 20 to provide water to the second water spray device 30; thus enabling one water pump 20 to provide water to at least two water spray devices, thereby saving the number of water pumps 20 used and reducing costs.

[0084] In some exemplary embodiments of this disclosure, reference is made to Figures 6-16 As shown, the switching mechanism 40 may include a housing 41 and a core 42. The housing 41 is provided with a main water inlet structure 411 and at least two water outlets 412. For example, the housing 41 may be provided with a main water inlet structure 411 and two water outlets 412; the housing 41 may also be provided with a main water inlet structure 411 and three or more water outlets 412.

[0085] The core 42 is provided with at least two water outlet channels 421. For example, the core 42 may be provided with two water outlet channels 421, or it may be provided with three or more water outlet channels 421. The number of water outlets 412 may be the same as the number of water outlet channels 421.

[0086] At least a portion of the core 42 is movably disposed within the housing 41 so that the main water inlet structure 411 is connected to different water outlets 412 through different water outlet channels 421; for example, a portion of the core 42 may be movably disposed within the housing 41, while another portion of the core 42 may be disposed outside the housing 41, or the entire core 42 may be disposed within the housing 41.

[0087] The following explanation uses an example with two water outlets 412 and two water outlet channels 421. (Refer to...) Figures 1-2 , Figures 6-16 As shown, the two water outlets 412 include a first water outlet 412a and a second water outlet 412b, and the two water outlet channels 421 include a first water outlet channel 421a and a second water outlet channel. The water outlet of the water pump 20 is connected to the main water inlet structure 411, the first water spray device 10 is connected to the first water outlet 412a, and the second water spray device 30 is connected to the second water outlet 412b. At least a portion of the core 42 is movably disposed within the housing 41, allowing the main water inlet structure 411 to be connected to the first water outlet 412a via the first water outlet channel 421a, thereby enabling the water pump 20 to provide water to the first water spray device 10; alternatively, the main water inlet structure 411 can be connected to the second water outlet 412b via the second water outlet channel, thereby enabling the water pump 20 to provide water to the second water spray device 30. This allows one water pump 20 to provide water to at least two water spray devices, thereby reducing the number of water pumps 20 used and lowering costs.

[0088] Reference Figure 8 and Figure 14As shown, the main water inlet structure 411 may include a main water inlet 4111 and at least two branch water outlets 4112, with the main water inlet 4111 connected to the at least two branch water outlets 4112; for example, the main water inlet structure 411 may include a main water inlet 4111 and two branch water outlets 4112, or the main water inlet structure 411 may include a main water inlet 4111 and three or more branch water outlets 4112. Generally, the number of branch water outlets 4112 can be the same as the number of water outlets 412.

[0089] The core 42 is provided with multiple sealing structures 424. The sealing structures 424 are used to seal the outer periphery of the branch outlet 4112 and the outer periphery of the outlet 412 under different conditions. The sealing structure 424 may include a sealing ring. The sealing structure 424 can prevent the leakage of liquid flowing through the branch outlet 4112 and the outlet 412.

[0090] In this case, refer to Figure 1 As shown, the water inlet of the water pump 20 can be used to connect to an external water source, that is, to provide water to the first water spraying device 10 and the second water spraying device 30 through an external water source.

[0091] Of course, in some other exemplary embodiments of this disclosure, the water spraying device may also include a liquid storage tank 80, which is connected to the water inlet of the water pump 20; that is, the liquid storage tank 80 provides a water source for the first water spraying device 10 and the second water spraying device 30.

[0092] The water source required by the switching mechanism 40 is the same water source connected to the water pump 20, which cannot meet the needs of the two water spraying devices that require different water sources.

[0093] In some exemplary embodiments of this disclosure, reference is made to Figures 3-4 , Figures 10-16 As shown, the housing 41 is also provided with a main water outlet structure 413 and at least two water inlets 414. For example, the housing 41 may also be provided with a main water outlet structure 413 and two water inlets 414, or the housing 41 may also be provided with a main water outlet structure 413 and three or more water inlets 414.

[0094] The core 42 is also provided with at least two water inlet channels 422. For example, the core 42 may also be provided with two water inlet channels 422, or the core 42 may be provided with three or more water inlet channels 422. The number of water inlets 414 may be the same as the number of water inlet channels 422.

[0095] The following description uses an example with two inlets 414 and two inlet channels 422. The two inlets 414 include a first inlet 414a and a second inlet 414b, and the two inlet channels 422 include a first inlet channel and a second inlet channel 422b. A main outlet structure 413 is used to connect to the inlet end of the water pump 20. At least a portion of the core 42 is movably disposed within the housing 41, allowing the main outlet structure 413 to be connected to different inlets 414 via different inlet channels 422. For example, the main outlet structure 413 can be connected to the first inlet 414a via the first inlet channel, allowing a water supply device connected to the first inlet 414a to provide a water source; the main outlet structure 413 can be connected to the second inlet 414b via the second inlet channel 422, allowing a water supply device connected to the second inlet 414b to provide a water source. This enables two different water supply devices to provide a water source to the water pump 20, thereby achieving water inlet switching.

[0096] For example, the water spraying device may also include a liquid storage tank 80, which has a first water outlet connected to a first water inlet 414a, making the liquid storage tank 80 a water supply device; and a second water inlet 414b for connecting to an external water source, making the external water source a water supply device.

[0097] When the main water inlet structure 411 is connected to the first water outlet 412a through the first water outlet channel 421a, the main water outlet structure 413 can be connected to the first water inlet 414a through the first water inlet channel, so that the liquid storage tank 80 provides water to the first water spraying device 10; when the main water inlet structure 411 is connected to the second water outlet 412b through the second water outlet channel, the main water outlet structure 413 can be connected to the second water inlet 414b through the second water inlet channel 422b, so that the external water source provides water to the second water spraying device 30; thereby satisfying the need to switch between different water supply sources for the first water spraying device 10 and the second water spraying device 30.

[0098] Reference Figures 12-15 As shown, the main water outlet structure 413 may include a main water outlet 4131 and at least two branch water inlets 4132, with the main water outlet 4131 connected to the at least two branch water inlets 4132; for example, the main water outlet structure 413 may include a main water outlet 4131 and two branch water inlets 4132, or the main water outlet structure 413 may include a main water outlet 4131 and three or more branch water inlets 4132. Generally, the number of branch water inlets 4132 can be the same as the number of water inlets 414.

[0099] Reference Figures 12-15As shown, the core 42 is provided with multiple sealing structures 424. The sealing structures 424 are used to seal the outer periphery of the sub-inlet 4132 and the outer periphery of the inlet 414 under different conditions. The sealing structure 424 may include a sealing ring. The sealing structure 424 can prevent the leakage of liquid flowing through the sub-inlet 4132 and the inlet 414.

[0100] The aforementioned inlet water switching section and outlet water switching section are integrally formed. However, in other exemplary embodiments of this disclosure, the inlet water switching section and outlet water switching section may also be separately formed; specifically, refer to... Figure 17 As shown, the switching mechanism 40 may further include an inlet housing 45 and an inlet core 46. The inlet housing 45 is provided with a main outlet structure 413 and at least two inlets 414. For example, the inlet housing 45 may be provided with a main outlet structure 413 and two inlets 414, or it may be provided with a main outlet structure 413 and three or more inlets 414. The main outlet structure 413 is used to connect to the inlet end of the water pump 20. The inlet core 46 is provided with at least two inlet channels 422, and at least a portion of the inlet core 46 is movably disposed within the inlet housing 45 so that the main outlet structure 413 is connected to different inlets 414 through different inlet channels 422.

[0101] In some exemplary embodiments of this disclosure, the housing 41 may include at least three connecting plates 415 connected end-to-end in sequence, the at least three connecting plates 415 being connected end-to-end in sequence to form a receiving cavity of the housing 41, and the core 42 being configured in a shape adapted to the receiving cavity. For example, the housing 41 may include three connecting plates 415 connected end-to-end in sequence, such that the housing 41 is configured as a cylindrical shape with both ends open of a triangular prism; in this case, the core 42 is configured as a triangular prism; see reference... Figures 6-12 As shown, the housing 41 may include four connecting plates 415 connected end to end in sequence, such that the housing 41 is a cylindrical shape with open ends of a quadrangular prism. In this case, the core 42 is a quadrangular prism. Of course, the housing 41 may include more connecting plates 415 connected end to end in sequence, which will not be described in detail here.

[0102] Reference Figures 6-12 As shown, a main water inlet structure 411 is provided on a connecting plate 415. Specifically, a main water inlet 4111 is provided on the outer side of the connecting plate 415, and two branch water outlets 4112 are provided on the inner side of the connecting plate 415.

The channel can be set in the shape of "[", or in the shape of "<", or other shapes, which will not be elaborated here. In addition, a main water inlet connecting pipe can be provided on the main water inlet 4111. The entire main water inlet connecting pipe can be referred to as the main water inlet 4111.
