Description
Technical Field
[0001] This utility model relates to the field of valve technology, and in particular to a regulating device and a cleaning device. Background Technology
[0002] In daily life, cleaning devices are a common cleaning tool widely used in vehicle washing, yard cleaning, and home sanitation. They remove stains by spraying water, thus improving cleaning efficiency. The precise adjustment of water flow is a key factor affecting the user experience of cleaning devices, and the required water flow varies significantly depending on the cleaning scenario (such as washing vehicle surfaces and cleaning crevices, small-area indoor cleaning, and large-area yard washing).
[0003] In the existing technology, the flow regulation structure of some cleaning devices is not reasonably designed. Their regulation components mostly adopt simple switch control or fixed channel structure, which makes it difficult to achieve continuous and precise adjustment of water flow. The water flow is either too large and causes splashing, or too small and affects cleaning efficiency. It is difficult to adapt to diverse cleaning needs, thus causing inconvenience to users.
[0004] Therefore, there is an urgent need for an adjustment device and a cleaning device to solve the above-mentioned technical problems. Utility Model Content

The first valve body and the second valve body are disposed opposite to each other. The second valve body is disposed on the drive component and has a flow hole that can selectively communicate with the flow channel.

[0013] Optionally, the drive assembly includes a first drive member, which is coaxially sleeved on the first adjustment mechanism and has a first passage communicating with the flow hole, and the second valve body is disposed on the first drive member.
[0014] Optionally, the inner peripheral wall of the first driving member extends radially to provide a limiting portion, which surrounds and forms the first passage.

[0022] This utility model provides an adjustment device and a cleaning device. The adjustment device includes a first adjustment mechanism and a second adjustment mechanism. The first adjustment mechanism includes a first valve body with a flow channel for a fluid medium. A second adjustment mechanism is rotatably connected to the first adjustment mechanism and includes a drive assembly and a second valve body. The first and second valve bodies are arranged opposite to each other. The second valve body is disposed on the drive assembly and has a flow hole selectively connected to the flow channel. When the drive assembly rotates relative to the first adjustment mechanism, it drives the second valve body to rotate synchronously relative to the first valve body.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0035] like Figures 1-5As shown, this embodiment provides an adjustment device, which includes a first adjustment mechanism 1 and a second adjustment mechanism 2. The first adjustment mechanism 1 includes a first valve body 11, which has a flow channel 111 for the passage of a fluid medium. The second adjustment mechanism 2 is rotatably connected to the first adjustment mechanism 1. The second adjustment mechanism 2 includes a drive assembly 21 and a second valve body 22. The first valve body 11 and the second valve body 22 are disposed opposite to each other. The second valve body 22 is disposed on the drive assembly 21 and has a flow hole 221 that can selectively communicate with the flow channel 111. When the drive assembly 21 rotates relative to the first adjustment mechanism 1, it drives the second valve body 22 to rotate relative to the first valve body 11 to adjust the size of the effective flow cross-sectional area of the flow hole 221 and the flow channel 111.
[0036] In this embodiment, the first regulating mechanism 1 includes a first valve body 11, which has a flow channel 111 for the passage of a fluid medium. A second regulating mechanism 2 is rotatably connected to the first regulating mechanism 1. The second regulating mechanism 2 includes a drive assembly 21 and a second valve body 22. The first valve body 11 and the second valve body 22 are disposed opposite to each other. The second valve body 22 is disposed on the drive assembly 21 and has a flow hole 221 that can selectively communicate with the flow channel 111. When the drive assembly 21 rotates relative to the first regulating mechanism 1, it drives the second valve body 22 to rotate synchronously relative to the first valve body 11. This process causes a gradual change in the overlapping area between the flow hole 221 and the flow channel 111, resulting in a continuous change in the effective flow cross-sectional area between them, thereby regulating the flow rate of the fluid medium. Through the above configuration, the regulating device of this embodiment can easily regulate the flow rate of the fluid medium, adapting to diverse scenario requirements.
[0037] It should be noted that in this embodiment, the effective flow cross-sectional area refers to the cross-sectional area of the overlapping region between the flow orifice 221 and the flow channel 111. The size of this area directly determines the actual flow rate of the fluid medium; the larger the area, the larger the flow rate, and when the area is zero, the fluid is cut off. By rotating the drive component 21 relative to the first adjustment mechanism 1, the second valve body 22 is driven to rotate relative to the first valve body 11, thereby adjusting the size of the effective flow cross-sectional area between the flow orifice 221 and the flow channel 111. This allows for different water volumes to be adjusted when cleaning different parts of the vehicle at varying distances, and also for different scenarios such as cleaning courtyards and restrooms. This improves scenario adaptability and avoids waste caused by large-area splashing of water.
[0038] The specific structure of the regulating device is described below:
[0039] Specifically, such as Figures 1-5As shown, the first adjusting mechanism 1 includes a fixing member 12, and the first valve body 11 is snapped into the fixing member 12, thereby realizing the quick assembly and disassembly of the first valve body 11 and the fixing member 12. The fixing member 12 extends along its own axial direction and is provided with a flow groove 121 communicating with the flow channel 111, which can provide a stable flow path for the fluid medium and ensure smooth fluid passage.
[0040] More specifically, in this embodiment, the overall structure of the fastener 12 is a circular tube to facilitate processing and assembly and reduce fluid flow resistance. Along the axial direction of the fastener 12, multiple grooves are spaced apart, extending circumferentially along the fastener 12 for assembly and connection with other components to meet the assembly requirements of different parts. In other embodiments, the fastener 12 may be a square tube or a non-circular tube; as long as the above functions are achieved, the specific structure of the fastener 12 is not limited here.
[0041] Specifically, the drive assembly 21 is coaxially sleeved on the outside of the fixing member 12, and the first valve body 11 and the second valve body 22 are both disposed between the fixing member 12 and the drive assembly 21 to improve the compactness of the overall structure, reduce the overall space occupied by the device, and facilitate installation in small equipment such as cleaning devices.
[0042] More specifically, in this embodiment, the fixing member 12 has an assembly groove at one end facing the drive assembly 21. The assembly groove extends along the inner peripheral wall of the fixing member 12 and is used to assemble the first valve body 11 to improve the positional stability of the first valve body 11 after assembly. The fixing member 12 and the drive assembly 21 form an accommodating space for accommodating the first valve body 11 and the second valve body 22, which not only facilitates assembly but also protects the first valve body 11 and the second valve body 22 from collision damage.
[0043] Specifically, the first adjustment mechanism 1 also includes a limiting member 13. The outer peripheral wall of the fixing member 12 is provided with a sliding groove 122 along its own circumferential direction. The limiting member 13 passes through the driving component 21 and the sliding groove 122 along the radial direction of the fixing member 12 and slides with the sliding groove 122. When the driving component 21 rotates relative to the fixing member 12, the limiting member 13 slides continuously in the sliding groove 122. This can ensure smooth rotation between the driving component 21 and the fixing member 12, making it convenient for users to control the flow rate of the fluid. It can also ensure that the driving component 21 and the fixing member 12 are both limited along their own axial direction, preventing relative displacement between the driving component 21 and the fixing member 12 in the axial direction and ensuring the stability of the overall structure.
[0044] Specifically, the drive assembly 21 includes a first drive member 211, which is coaxially sleeved with the first adjustment mechanism 1 to ensure that its central axis is consistent with the central axis of the first adjustment mechanism 1, thereby reducing eccentric shaking during rotation. The first drive member 211 is provided with a first passage 2111 that communicates with the flow hole 221, so that fluid can enter the flow hole 221 through the first passage 2111, thereby ensuring the continuity of fluid flow. The second valve body 22 is disposed on the first drive member 211, thereby forming a stable support for the second valve body 22 and ensuring that the second valve body 22 and the first drive member 211 can rotate synchronously.
[0045] More specifically, the first valve body 11 and the first drive member 211 surround to form a flow channel 111, that is, the inner wall of part of the flow channel 111 is disposed in the first valve body 11, and the inner wall of the remaining part of the flow channel 111 is disposed in the first drive member 211, thereby simplifying the overall structural design.
[0046] Specifically, the inner peripheral wall of the first driving member 211 extends radially and is provided with a limiting part 2112, which forms a first passage 2111. The second adjusting mechanism 2 also includes a sealing member 23, which is sandwiched between the limiting part 2112 and the second valve body 22. The sealing member 23 can both block the gap between the limiting part 2112 and the second valve body 22 to prevent fluid leakage and also provide axial limiting for the second valve body 22 through the limiting part 2112. The sealing member 23 can be a rubber ring or a silicone ring, as long as it can achieve a seal between the limiting part 2112 and the second valve body 22. The specific structure of the sealing member 23 is not specified here.
[0047] Specifically, in the first driving member 211 and the second valve body 22, one is provided with a limiting groove 2113, and the other is provided with a limiting protrusion 222 that cooperates with the limiting groove 2113 to achieve circumferential positioning between the first driving member 211 and the second valve body 22, ensuring that the two move synchronously and avoiding the failure of adjustment action transmission caused by the relative circumferential sliding between the first driving member 211 and the second valve body 22.
[0048] More specifically, in this embodiment, the inner peripheral wall of the first driving member 211 is provided with a limiting groove 2113 facing each other, and the outer peripheral wall of the second valve body 22 is provided with limiting protrusions 222 on both sides facing each other. The limiting protrusions 222 correspond one-to-one with the limiting grooves 2113, so that the second valve body 22 is limited to the first driving member 211 along its own circumference, ensuring that the two can rotate synchronously relative to the fixing member 12, and avoiding the displacement between the first driving member 211 and the second valve body 22 when the first driving member 211 rotates.
[0049] In other embodiments, the limiting groove 2113 is disposed on the second valve body 22 and the limiting protrusion 222 is disposed on the first driving member 211, which can also achieve the above-mentioned function. Here, the specific position of the above-mentioned components is not limited in too much.
[0050] Specifically, the drive assembly 21 also includes a second drive member 212, which is coaxially snapped onto the first drive member 211 to enable quick assembly and disassembly of the second drive member 212 and the first drive member 211, facilitating later maintenance or component replacement. The second drive member 212 is provided with a second passage 2121, one end of which is connected to the first passage 2111 to ensure smooth flow of fluid from the second passage 2121 to the first passage 2111. The other end of the second passage 2121 is configured to be detachably connected to the connector 100, which not only facilitates the flow of water from the connector 100 into the first passage 2111 and the second passage 2121, but also allows for compatibility with different specifications and types of connectors 100, thereby enhancing the versatility of the device.
[0051] More specifically, in this embodiment, both the first driving member 211 and the second driving member 212 are sleeve structures, which facilitates processing and assembly. One end of the first driving member 211 is rotatably connected to the fixing member 12, and the other end of the first driving member 211 is engaged with one end of the second driving member 212, which not only ensures the rotation adjustment function of the driving assembly 21, but also facilitates the independent processing and assembly of each component. In other embodiments, both the first driving member 211 and the second driving member 212 are stepped shafts or irregularly shaped sleeve structures, which can also achieve the above-mentioned functions. Therefore, the specific structure of the above components is not limited further.
[0052] Specifically, the outer peripheral wall of the second drive member 212 is provided with an anti-slip part 2122, which can increase the friction during user operation, making it easier for the user to hold and rotate the second drive member 212 for flow adjustment. The anti-slip part 2122 includes, but is not limited to, anti-slip textures or anti-slip protrusions, and the specific structure of the anti-slip part 2122 is not limited here.
[0053] The specific working process of the regulating device is explained below:
[0054] When the water flow needs to be increased, the user holds the anti-slip part 2122 of the second drive member 212, causing the first drive member 211 and the second drive member 212 to rotate relative to the fixed member 12. At this time, the limiting member 13, which passes through the drive assembly 21 and the sliding groove 122, slides synchronously with the first drive member 211 and the second drive member 212 in the sliding groove 122, ensuring that the drive assembly 21 and the fixed member 12 rotate smoothly and are axially limited. Since the first drive member 211 and the second valve body 22 are limited and cooperated by the limiting groove 2113 and the limiting protrusion 222, when the first drive member 211 rotates, it will drive the second valve body 22 to rotate synchronously relative to the first valve body 11. This causes the effective flow cross-sectional area of the flow hole 221 of the second valve body 22 and the flow channel 111 of the first valve body 11 to gradually increase. The flow rate of the fluid medium passing through the second passage 2121, the first passage 2111, the flow hole 221 and the flow channel 111 in sequence increases accordingly, thereby realizing the increase of water flow.
[0055] When it is necessary to reduce the water flow, the user rotates the second drive component 212 in the opposite direction, causing the second valve body 22 to rotate in the opposite direction relative to the first valve body 11. The effective flow cross-sectional area of the flow hole 221 and the flow channel 111 gradually decreases, and the flow rate of the fluid medium decreases accordingly, thus achieving the reduction of water flow.
[0056] If it is necessary to shut off the water flow, continuously rotate the second drive component 212 in the opposite direction until the effective flow cross-sectional area of the flow hole 221 and the flow channel 111 is zero, and the fluid medium cannot pass through, at which point the water flow is shut off.
[0057] In addition, this embodiment also provides a cleaning device, which includes a main body 200 and the above-mentioned adjustment device. The first adjustment mechanism 1 is connected to the main body 200, so that the user can directly rotate the drive component 21 to adjust the water flow rate during the use of the cleaning device, which is more convenient and faster.
[0058] Specifically, the main body 200 has an installation port 201 at its water outlet. The installation port 201 is configured to be detachably connected to the replacement head, allowing users to replace and combine replacement heads with different functions to meet different usage needs. The replacement heads include, but are not limited to, brush heads, direct spray heads, shower heads, and foam heads. The aforementioned detachable connection includes, but is not limited to, snap-fit or screw-fit methods, which are not further specified here.
[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
