[0007] Furthermore, each liquid supply branch includes a connecting channel, and each liquid outlet is connected to the liquid supply channel through a corresponding connecting channel; wherein, the minimum flow cross-sectional area of ​​the liquid supply branch is the minimum flow cross-sectional area of ​​each corresponding connecting channel.

[0008] Furthermore, the main structure is provided with a blocking part, which is located between the liquid supply channel and multiple liquid outlets. The connecting channel includes a flow hole located in the blocking part, and the minimum flow cross-sectional area of ​​the liquid supply branch is the area of ​​the flow hole.

[0009] Furthermore, the main structure includes: a support component; a liquid supply component, wherein the liquid supply component is installed on the support component, and the liquid outlet is located on the liquid supply component, and the support component and the liquid supply component form a liquid supply channel.

[0010] Furthermore, the liquid inlet is located on the support member, and the support member and the liquid supply member are sealed together at the contact point; and / or, the support member and the liquid supply member are detachably connected.

[0011] Furthermore, when a blocking part is provided on the main structure: the blocking part is provided on the liquid supply component, and a groove is provided on the side of the blocking part near the support component, with the depth direction of the groove facing the liquid supply component, and the groove and the support component forming a flow hole; or, the blocking part is provided on the support component, and a groove is provided on the side of the blocking part near the liquid supply component, with the depth direction of the groove facing the support component, and the groove and the liquid supply component forming a flow hole.

[0012] Furthermore, along the direction away from the liquid inlet, the depth of the groove corresponding to each liquid outlet increases sequentially.

[0013] Furthermore, the main structure has a first end and a second end, with the first end and the second end positioned opposite each other, and the liquid inlet located at the first end; along the direction from the first end to the second end, the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each liquid outlet gradually increases.

[0014] Furthermore, the main structure has a first end and a second end, which are arranged opposite to each other, and the liquid inlet is located between the first end and the second end; along the direction from the liquid inlet to the first end, the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each liquid outlet gradually increases; along the direction from the liquid inlet to the second end, the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each liquid outlet gradually increases.

[0015] According to another aspect of the present invention, a cleaning device is provided, comprising: a cleaning apparatus for cleaning the surrounding environment; and a liquid supply apparatus, which is the aforementioned liquid supply apparatus, and is positioned corresponding to the cleaning apparatus to supply liquid to different positions of the cleaning apparatus through multiple liquid outlets of the liquid supply apparatus.

[0016] The liquid supply device using the technical solution of this utility model includes a main structure, wherein the main structure is provided with: a liquid supply channel for liquid to flow through; a liquid inlet connected to the liquid supply channel to supply liquid to the liquid supply channel; and multiple liquid outlets arranged along the extension direction of the liquid supply channel, each liquid outlet being connected to the liquid supply channel so that liquid in the liquid supply channel flows out through the multiple liquid outlets; wherein the channel between the liquid supply channel and any liquid outlet is a liquid supply branch, and the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each liquid outlet gradually increases along the direction away from the liquid inlet.

When liquid flows along the supply channel, a pressure drop occurs within the channel along the flow direction, resulting in pressure differences at each outlet. This invention addresses this issue by designing the supply branches between each outlet and the supply channel such that the minimum flow cross-sectional area of ​​the supply branch corresponding to each outlet gradually increases along the direction away from the inlet. Thus, the lower the liquid pressure, the larger the minimum flow cross-sectional area of ​​the supply branch corresponding to the outlet, thereby increasing the liquid flow rate at the outlet. This results in more uniform liquid output at each outlet, reducing or avoiding poor flow uniformity at different outlets due to pressure drop within the supply channel. This improves the uniformity of liquid output from the supply device and solves the technical problem of poor liquid supply uniformity in related technologies. Attached Figure Description

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Please refer to Figures 1 to 7 To address the technical problems described in the background section, embodiments of this utility model provide a liquid supply device, comprising a main structure 1, wherein the main structure 1 is provided with: a liquid supply channel 11 for supplying liquid to flow therethrough; a liquid inlet 12 connected to the liquid supply channel 11 to supply liquid to the liquid supply channel 11 through the liquid inlet 12; and a plurality of liquid outlets 13 arranged sequentially along the extension direction of the liquid supply channel 11, each liquid outlet 13 being connected to the liquid supply channel 11 so that liquid in the liquid supply channel 11 flows out through the plurality of liquid outlets 13; wherein the channel between the liquid supply channel 11 and any liquid outlet 13 is a liquid supply branch, and along the direction away from the liquid inlet 12, the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each liquid outlet 13 gradually increases.

[0029] The liquid supply device with this structural design has a main structure 11 equipped with a liquid supply channel 11, an inlet 12, and multiple outlets 13. The liquid to be supplied enters the liquid supply channel 11 through the inlet 12, is then transported through the liquid supply channel 11 to each outlet 13, and is subsequently discharged through the multiple outlets 13, thus supplying liquid to various locations. When the liquid flows along the liquid supply channel 11, a pressure drop occurs within the liquid supply channel 11 along the flow direction, resulting in different pressures at each outlet 13. In this embodiment, the liquid supply branches between each outlet 13 and the liquid supply channel 11 are designed such that, along the direction away from the inlet 12, the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each outlet 13 gradually increases. In this way, the smaller the liquid pressure at a location, the larger the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to the outlet 13, thereby increasing the liquid flow rate at the outlet 13. This makes the liquid output from the outlet 13 at each location more uniform, which can reduce or avoid the situation where the liquid flow rate of different outlets 13 is not uniform due to the pressure drop inside the liquid supply channel. This improves the uniformity of liquid output of the liquid supply device and solves the technical problem of poor uniformity of liquid supply in related technologies.

[0030] It should be noted that in actual implementation, it is sufficient for the main structure 1 of the liquid supply device to have multiple liquid outlets 13 that meet the above requirements. In addition, the liquid supply device may also have other liquid outlets. For example, in one optional embodiment, the main structure 1 of the liquid supply device is provided with multiple liquid outlets 13, wherein at least one liquid outlet 13 meets the above-mentioned flow cross-sectional area requirements for the liquid supply branch. As another example, in another optional embodiment, the main structure 1 of the liquid supply device is provided with ten liquid outlets 13, and a portion of these ten liquid outlets 13 can be selected to meet the above-mentioned flow cross-sectional area requirements for the liquid supply branch.

[0031] It is understandable that for any liquid supply branch, it starts at the liquid supply channel 11 and ends at the outer surface of the corresponding liquid outlet 13.

[0032] The minimum flow cross-sectional area is the minimum area of ​​the flow cross-section at each location of the liquid supply branch. Specifically, along the extension direction of the liquid supply branch, a cross-section perpendicular to the flow direction is made at each location. For any cross-section, the area enclosed by the inner wall of the liquid supply branch is the flow cross-sectional area at that location. For this liquid supply branch, the minimum value of the flow cross-sectional area along its extension direction is taken, which is the aforementioned minimum flow cross-sectional area. In actual implementation, the specific structural form of each liquid supply branch can vary. For example, it can be a channel set inside the main structure 1, or a pipe connecting the liquid supply channel 11 and the corresponding outlet 13. The cross-sectional area at the narrowest point of this channel or pipe corresponds to the aforementioned minimum flow cross-sectional area, which determines the flow rate of the liquid supply branch.

[0033] For example, in one optional embodiment, each outlet 13 is connected to the supply channel 11 via a single pipe. In this case, each supply branch is a single pipe. If the pipe has a uniform diameter, the minimum flow cross-sectional area of ​​the supply branch is the area enclosed by the inner wall of the pipe. If the pipe has an uneven diameter (some sections are thicker than others), the minimum flow cross-sectional area of ​​the supply branch is the area enclosed by the inner wall of the thinnest section.

[0034] For example, in another alternative implementation, such as Figure 1 and Figure 2 As shown, the channel between the liquid supply channel 11 and the liquid outlet 13 is a liquid supply branch, which can be regular or irregular in shape. For example... Figure 2 As shown in this embodiment, the flow cross-sectional area at each location of the liquid supply branch is different along the liquid flow direction. The flow cross-sectional area corresponding to point C is the minimum flow cross-sectional area of ​​the liquid supply branch, which is significantly smaller than the flow cross-sectional area corresponding to point B.

[0035] In this embodiment, each liquid supply branch includes a connecting channel, and each liquid outlet 13 is connected to the liquid supply channel 11 through a corresponding connecting channel. The minimum flow cross-sectional area of ​​each liquid supply branch is the minimum area of ​​the flow cross-section of the corresponding connecting channel. By using connecting channels to connect the liquid supply channel 11 to the corresponding liquid outlet 13, and by designing the flow cross-sectional area of ​​the connecting channels, the minimum flow cross-sectional area of ​​each liquid supply branch can be controlled. In this embodiment, the opening size and / or opening shape of multiple liquid outlets 13 are the same. For example, when the liquid outlet 13 is circular, the orifice diameter of multiple liquid outlets 13 is the same, thereby ensuring the consistency of the liquid discharge state at each liquid outlet 13 and avoiding the shape and / or size of the liquid outlet 13 from affecting the liquid discharge state.

[0036] In another optional implementation, in order to facilitate the control of the minimum flow cross-sectional area of ​​each liquid supply branch, the multiple liquid outlets 13 are of different sizes (i.e., different opening areas). In this case, the minimum flow cross-sectional area of ​​the liquid supply branch is the area of ​​each liquid outlet 13, so that there is no need to change the internal channel, which facilitates the processing and manufacturing of the liquid supply device.

[0037] Specifically, the main structure 1 is provided with a blocking part 15, which is located between the liquid supply channel 11 and multiple liquid outlets 13. The connecting channel includes a flow hole 150 provided in the blocking part 15, and the minimum flow cross-sectional area of ​​the liquid supply branch is the area of ​​the flow hole 150.

[0038] In this embodiment, a blocking part 15 is provided on the main structure 1, and a flow hole 150 is provided on the blocking part 15. The minimum flow cross-sectional area of ​​each liquid supply branch is the area of ​​the corresponding flow hole 150. In this way, by controlling the size of each flow hole 150, the uniformity of liquid supply can be easily controlled.

[0039] In some optional embodiments, the main structure 1 includes: a support member 16; a liquid supply member 17, the liquid supply member 17 being installed on the support member 16, the liquid outlet 13 being disposed on the liquid supply member 17, and the support member 16 and the liquid supply member 17 forming a liquid supply channel 11.

[0040] In a preferred embodiment, the support member 16 and the liquid supply member 17 are detachably disposed, i.e., they can be separated. By designing the main structure 1 of the liquid supply device as a detachable structure consisting of the support member 16 and the liquid supply member 17, the inside of the liquid supply channel 11 can be cleaned by separating the two. Thus, when the inside of the liquid supply device is blocked by debris, scale, etc., the liquid supply channel 11 can be fully exposed by separating the support member 16 and the liquid supply member 17, making it easy to perform cleaning and maintenance operations.

[0041] Specifically, the liquid inlet 12 is provided on the support member 16; and / or, the support member 16 and the liquid supply member 17 are sealed together at the contact point.

[0042] In one specific embodiment, the liquid inlet 12 is located on the support 16 to ensure its installation reliability. The contact point between the support 16 and the liquid supply component 17 is sealed to prevent leakage due to gaps between them. In actual implementation, different implementation schemes can be adopted to meet the sealing requirements.

[0043] For example, in one alternative embodiment, at least a portion of the liquid supply element 17 is made of a flexible material (e.g., soft rubber), and when the liquid supply element 17 is mounted on the support 16, the pressure points of the liquid supply element 17 deform, thereby fitting more closely to the support 16.

[0044] For example, in another alternative embodiment, a sealing gasket is provided between the liquid supply member 17 and the support member 16, thereby further improving the sealing between the two.

[0045] In this embodiment, the support member 16 is made of a flexible material, and the support member 16 and the liquid supply member 17 are engaged in a snap-fit ​​connection, thereby simplifying the structure and reducing the difficulty of operation while ensuring sealing. Of course, if structural complexity and operational difficulty are not considered, other connection methods can also be used between the two, such as connection by fasteners.

[0046] In this embodiment, when the main structure 1 is provided with a blocking part 15: the blocking part 15 is provided on the liquid supply member 17, and the blocking part 15 is provided with a groove 14 on the side near the support member 16, the depth direction of the groove 14 is towards the liquid supply member 17, and the groove 14 and the support member 16 form a flow hole 150; or, the blocking part 15 is provided on the support member 16, and the blocking part 15 is provided with a groove 14 on the side near the liquid supply member 17, the depth direction of the groove 14 is towards the support member 16, and the groove 14 and the liquid supply member 17 form a flow hole 150.

[0047] Specifically, along the direction away from the liquid inlet 12, the depth of the groove 14 corresponding to each liquid outlet 13 increases sequentially.

[0048] like Figure 6 As shown, the rightmost slot 14 is closest to the liquid inlet 12 and has the smallest depth. The left slot 14 is far from the liquid inlet 12 and therefore has a larger depth. At this time, the height difference between the bottom of the two slots and the same reference position satisfies L1 > L2.

[0049] In an optional embodiment, the main structure 1 has a first end and a second end, the first end and the second end are arranged opposite to each other, and the liquid inlet 12 is arranged at the first end; along the direction from the first end to the second end, the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each liquid outlet 13 gradually increases.

[0050] In another optional embodiment, the main structure 1 has a first end and a second end, the first end and the second end are arranged opposite to each other, and the liquid inlet 12 is arranged between the first end and the second end; along the direction from the liquid inlet 12 to the first end, the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each liquid outlet 13 gradually increases; along the direction from the liquid inlet 12 to the second end, the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each liquid outlet 13 gradually increases.

[0051] In addition, an embodiment of the present invention also provides a cleaning device, which includes: a cleaning device 10 for cleaning the surrounding environment; and a liquid supply device, which is the liquid supply device described above, and is arranged in a position corresponding to the cleaning device 10, so as to supply liquid to different positions of the cleaning device 10 through multiple liquid outlets 13 of the liquid supply device.

[0052] In a preferred embodiment, the cleaning equipment includes a bracket, on which the cleaning device 10 and the liquid supply device are mounted. The bracket is detachably mounted from the main body of the cleaning equipment, thereby facilitating the removal of the cleaning device 10 and the liquid supply device from the main body of the cleaning equipment for maintenance.

[0053] In a preferred embodiment, the support member 16 is the bracket described above, thereby further simplifying the structure of the cleaning equipment and reducing its manufacturing cost.

[0054] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0055] The liquid supply device of this utility model embodiment includes a main structure 1, wherein the main structure 1 is provided with: a liquid supply channel 11, which is used to supply liquid to flow therethrough; a liquid inlet 12, which is connected to the liquid supply channel 11 to supply liquid to the liquid supply channel 11 through the liquid inlet 12; and a plurality of liquid outlets 13, which are arranged sequentially along the extension direction of the liquid supply channel 11, and each liquid outlet 13 is connected to the liquid supply channel 11 so that the liquid in the liquid supply channel 11 flows out through the plurality of liquid outlets 13; wherein, the channel between the liquid supply channel 11 and any liquid outlet 13 is a liquid supply branch, and along the direction away from the liquid inlet 12, the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each liquid outlet 13 gradually increases. The liquid supply device with this structural design has a main structure 11 equipped with a liquid supply channel 11, an inlet 12, and multiple outlets 13. The liquid to be supplied enters the liquid supply channel 11 through the inlet 12, is then transported through the liquid supply channel 11 to each outlet 13, and is subsequently discharged through the multiple outlets 13, thus supplying liquid to various locations. When the liquid flows along the liquid supply channel 11, a pressure drop occurs within the liquid supply channel 11 along the flow direction, resulting in different pressures at each outlet 13. In this embodiment, the liquid supply branches between each outlet 13 and the liquid supply channel 11 are designed such that, along the direction away from the inlet 12, the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to each outlet 13 gradually increases. In this way, the smaller the liquid pressure at a location, the larger the minimum flow cross-sectional area of ​​the liquid supply branch corresponding to the outlet 13, thereby increasing the liquid flow rate at the outlet 13. This makes the liquid output from the outlet 13 at each location more uniform, which can reduce or avoid the situation where the liquid flow rate of different outlets 13 is not uniform due to the pressure drop inside the liquid supply channel. This improves the uniformity of liquid output of the liquid supply device and solves the technical problem of poor uniformity of liquid supply in related technologies.
