Description

Technical Field

[0001] This manual relates to the field of rinsing products technology, and in particular to a water circuit switching device and a rinsing spray gun. Background Technology

[0002] Handheld spray guns are a common accessory in modern bathrooms, and their user experience directly impacts the cleaning experience. Currently, the mainstream products on the market are divided into two categories: rocker-button single-function spray guns and vertical center-button single-button spray guns. However, with the increasing demand from users for diversified rinsing scenarios and miniaturized products, the existing structures have obvious technical shortcomings.

[0003] Most handheld spray guns are single-function spray guns with a single water output mode, which cannot adapt to the water needs of multiple scenarios. One set of spray guns cannot cover all washing scenarios in the bathroom, resulting in a poor user experience and insufficient product versatility.

[0004] Therefore, there is an urgent need for a water path switching device that can be adapted to the flushing spray gun and simultaneously achieve independent control of the two water paths. Summary of the Invention

[0005] This manual provides a water path switching device and a flushing spray gun, which can solve the problems existing in related technologies.

[0006] In a first aspect, this disclosure provides a waterway switching device for switching the connection state between a main waterway and different branch waterways, including: The main body has the main waterway and two branch waterways, and the main waterway can be connected to the two branch waterways. The switching component includes a first switching part, a balancing elastic element, and a second switching part disposed within the main body. The balancing elastic element is located between the first switching part and the second switching part and is used to reset the first switching part and the second switching part. The first control component is installed on the main body and is directly or indirectly connected to the first switching unit; The second control component is installed on the main body and is directly or indirectly connected to the second switching unit; The switching component is normally closed. Under normal conditions, the main waterway and the two branch waterways are simultaneously closed. When the first control component is driven, it causes the first switching part to move toward the second switching part, and the main waterway and one of the two branch waterways switch from a closed state to a connected state. After the first control component is driven to terminate, the balancing elastic element resets the first switching part. When the second control component is driven, it moves the second switching part toward the first switching part, switching the main waterway from a closed state to a connected state with the other of the two branch waterways. After the first control component is terminated, the balancing elastic element resets the second switching part. The above-mentioned waterway switching device is a coordinated arrangement of the main waterway and the two branch waterways. Specifically, the main body carries the main waterway and the two branch waterways. This arrangement integrates and unifies the waterway flow carrier, simplifies the overall size of the device, and makes the docking positions of different waterways more regular, reducing the risk of installation and docking deviations. The switching component can arrange the first switching part, the balancing elastic element, and the second switching part in sequence. The balancing elastic element is placed between the two switching parts, providing reset force to both switching parts simultaneously. This eliminates the need for separate reset elements for each switching part, reducing the number of parts and compressing the internal space occupied by the device. The two control components (the first control component and the second control component) independently dock with the two switching parts (the first switching part and the second switching part), ensuring that the switching control of the two waterways does not interfere with each other, avoiding the false triggering problem that is prone to occur in single control structures, and improving the reliability of the switching action.

[0007] The normally closed configuration combined with dual-control independent drive makes the device more suitable for actual standby conditions during water outages: it eliminates the need for additional drive force to maintain the closed state, consumes no extra energy in standby mode, and avoids accelerated component aging due to continuous stress. The action combination of the first control component driving the first switching unit to move towards the second switching unit to open one side of the water channel, and the second control component driving the second switching unit to move towards the first switching unit to open the other side of the water channel, relies on the opposing movement of the two switching units to achieve single-channel opening. This eliminates the need for additional multi-channel independent blocking structures, resulting in simpler operational logic and a lower probability of jamming failures. The combined configuration of the balancing elastic element between the two switching units ensures that when one side of the switching unit is activated, the elastic force of the element also helps stabilize the position of the other side's switching unit, preventing accidental connection of unrelated water channels.

[0008] The above-mentioned complete set of devices can achieve the function of independent switching between two water channels with fewer parts, and the overall structure is more compact, making it suitable for installation in water channel scenarios with limited space; the dual independent control supports opening any one water channel as needed, making it more flexible to use; the normally closed plus elastic reset design reduces ineffective energy consumption and component wear, resulting in a longer overall service life of the device and lower failure maintenance costs.

[0009] In some examples, the two water channels include a first water channel and a second water channel; The first switching unit includes: The first guide section is capable of extending into the first water distribution channel; A first sealing part is disposed on the periphery of the first guide part for sealing the first water channel; The first receiving part is connected to the first guide part and located at the end of the first guide part, and is disposed on the outside of the first water channel, for receiving the balance elastic element; The second switching unit includes: The second guide section can extend into the second water distribution channel; The second sealing part is disposed on the periphery of the second guide part and is used to seal the second water channel; The second receiving part, connected to the second guide part and located at the end of the second guide part, is disposed on the outside of the second water channel and is used to receive the balancing elastic element.

[0010] The first and second switching parts mentioned above adopt a isomorphic combination design of guiding, sealing and external support, which reduces the processing complexity of the overall structure. The structural specifications of the two switching parts can be designed and produced in a unified manner, which reduces the types of parts and processing steps, and reduces the production and manufacturing costs as well as the cost of replacing parts for later maintenance. The two switching components each correspond to an independent water channel, and each completes the on / off switching action of its corresponding water channel without interference. When one switching component closes its corresponding water channel, the other switching component can open the other water channel. The actions are highly complementary, and the switching process will not result in both channels closing or opening simultaneously, making water control more stable. In addition, both switching components provide support for the balancing elastic element through the outer bearing part. The two switching components can be symmetrically arranged on both sides of the balancing elastic element, resulting in more balanced overall force distribution. This can offset the structural eccentric load caused by unilateral elastic force, further improving the operational stability of the entire switching assembly and reducing the probability of structural deformation after long-term use.

[0011] In some examples, the radial cross-section of the first sealing portion and / or the second sealing portion is at least partially tapered, and a tapered sealing surface is formed on the outer peripheral side.

[0012] The aforementioned conical sealing surface can better fit the mating sealing contact surface, adapt to the minor machining errors and assembly tolerances of the contact surface, thereby achieving a better sealing effect than conventional flat or curved surface structures. Under long-term pressure or temperature change conditions, it is also less prone to sealing failure due to structural deformation or material aging.

[0013] Furthermore, when used in conjunction with a balancing elastic element, the balancing elastic element can continuously provide a stable preload to the conical sealing structure, compensating for the minute gaps that occur after long-term use, and further improving the stability and service life of the sealing system.

[0014] In some examples, a first snap-fit ​​groove is provided on the first receiving part, and the first end of the balancing elastic member snaps into the first snap-fit ​​groove; The second receiving part is provided with a second snap-fit ​​groove, and the second end of the balancing elastic member is snapped into the second snap-fit ​​groove.

[0015] The above structure can be equipped with independent snap-fit ​​grooves at both receiving parts, with the two ends of the balancing elastic element respectively embedded into the first snap-fit ​​groove and the second snap-fit ​​groove to complete the snap-fit ​​fixation. The above structure breaks down the elastic element, which originally required integral molding or additional connecting parts for fixation, into an assembly form with snap-fit ​​at both ends, simplifying the overall structural design. It eliminates the need for additional pressure plates, bolts, and other fixing parts, reducing structural complexity and overall space occupation.

[0016] In some examples, the first switching part further includes a first reinforcing part, which is disposed at the junction of the first receiving part and the first guide part; The second switching section also includes a second reinforcing section, which is located at the junction of the second receiving section and the second guide section.

[0017] The aforementioned first and second reinforcing sections, serving as incremental structures at corresponding junctions, directly fill the structural strength gaps at the connection points between the first receiving section and the first guide section, and between the second receiving section and the second guide section. These two junctions are the core areas where the switching section bears external impacts and experiences stress concentration. The receiving section is responsible for bearing the action load transmitted by the trigger, while the guide section provides directional constraints for the switching action. The connection point between these two is the weakest node in the entire force chain of the switching section. The reinforcing sections directly strengthen this weak node, achieving targeted reinforcement of the stress-weak points through structural layout.

[0018] In some examples, the first control component includes: The first pressing member is movably connected to the main body, and when driven, the first pressing member can directly or indirectly press the first switching part. The first elastic element has a first end connected to the first pressing element and a second end connected to the main body or the first switching part. The first elastic element is used to drive the first pressing element to reset. After being driven, the first pressing member overcomes the elastic force of the first elastic member and directly or indirectly drives the first switching part to open the first water channel. And / or, the second control component includes: The second pressing member is movably connected to the main body. When driven, the second pressing member can directly or indirectly press the second switching part. The second elastic element has a first end connected to the second pressing element and a second end connected to the main body or the second switching part. The second elastic element is used to drive the second pressing element to reset. After being driven, the second pressing member overcomes the elastic force of the second elastic member and directly or indirectly drives the second switching part to open the second water channel.

[0019] The above structure is a further refinement of the structure of the first control component and the second control component. Specifically, the pressing component and the elastic component can be treated as separate functional units, and then connected to the main body and the switching part. The independent control of the two water channels is clearly defined at the structural level. Each control component corresponds only to its own switching part and will not interfere with each other, thus realizing the modular decomposition of the control link.

[0020] In some examples, the first control component also includes: The first lever is rotatably connected to the first pressing member or the main body. The first lever includes an integrally formed first rotating part, a first driven part and a first driving part, and the first driven part and the first driving part are arranged at an angle. A first torsion spring is installed on the first rotating part. The first lever arm of the first torsion spring acts on the first pressing member or the main body, and the second lever arm of the first torsion spring acts on the first driven part or the first driving part. After being driven, the first pressing member drives the first lever to rotate relative to it, and drives the first switching part. The first torsion spring is used to drive the first lever to reset. And / or, the second control component further includes: The second lever is rotatably connected to the second pressing member or the main body. The second lever includes an integrally formed second rotating part, a second driven part and a second driving part. The second driven part and the second driving part are set at an angle. The second torsion spring is installed on the second rotating part. The second lever arm of the second torsion spring acts on the second pressing member or the main body. The second lever arm of the second torsion spring acts on the second driven part or the second driving part. When the second pressing member is driven, it causes the second lever to rotate relative to it, and drives the second switching part. The second torsion spring is used to drive the second lever to reset.

[0021] The above structure is a further modification of the first and second control components. By adding two independent components—a lever and a torsion spring—more stable and reliable functions can be achieved. The lever includes three functional sections: a rotating part, a driven part, and a driving part. It can change the direction of the driven force, for example, converting radial force into axial force. A transmission and reset path can also be constructed through a rotational connection and torsion spring force application. This clearly defines three independent functional modules: pressing force, transmission reversal, and reset springback, avoiding structural interference caused by integrating multiple functions into a single part.

[0022] In some examples, a balance bar is provided on the first pressing element and / or the second pressing element.

[0023] The aforementioned balance bar is an additional structure directly mounted on the pressing component. It corrects force offsets that occur during repeated pressing, ensuring the pressing component always moves in the preset direction and preventing misalignment or jamming between the pressing component and adjacent parts. This simplifies the design of additional correction structures. Derivation: Over long-term use, the pressing component's force points are prone to uneven distribution due to operational deviations. Unilateral force can cause the pressing component to tilt and jam. By directly mounting a balance bar on the pressing component, the force can be balanced with the support of the bar, offsetting the deflection torque caused by unilateral force and structurally preventing tilting. Practical Effects: It effectively extends the lifespan of the pressing component, reduces the probability of jamming during pressing, provides a smoother and more consistent user experience, and avoids adding excessive structural complexity, balancing user experience with ease of manufacturing and assembly.

[0024] In some examples, the two water channels are a shower channel and a blade channel, with a shower structure at the end of the shower channel and a blade water structure at the end of the blade channel.

[0025] The shower head structure described above has a relatively dispersed water output and a wide coverage area, which can quickly wet and initially rinse a large area to be cleaned, removing floating dust and large particles of impurities attached to the surface.

[0026] The blade water structure concentrates the water flow and has a stronger impact, which can penetrate deep into crevices to flush away stubborn stains and specifically clean residual dirt that is difficult to remove by the shower head structure.

[0027] The combination of two water outlet structures can balance cleaning efficiency and solve the problem of cleaning hard-to-reach areas. Compared with a single water outlet structure, it can complete high-quality cleaning in a shorter time and improve the overall user experience.

[0028] Secondly, a flushing spray gun includes: The aforementioned water path switching device can switch between the shower head water path and the blade water path; The shower head structure is connected to the shower head water channels; and Blade water structure, connected to blade water channels.

[0029] This disclosed rinsing spray gun integrates the water path switching device with the shower head and blade water structure, fundamentally solving the pain point of traditional rinsing equipment that requires multiple external water interfaces and different water outlets to switch water modes. In actual use, traditional rinsing equipment often requires two separate water outlet devices or switching modes by disassembling and replacing water outlets to achieve both gentle shower water and high-pressure blade water functions. This process not only interrupts the current rinsing operation but also requires storing the idle water outlet, wasting operation time and increasing storage space. For scenarios such as home cleaning, bathroom rinsing, or car washing, the user experience is very unsmooth. However, this disclosed device directly switches the internal water path through the built-in water path switching device, without any external disassembly. Users only need to operate the switching device to change the water mode in a short time (e.g., within 1-3 seconds). The entire process does not require taking your hands off the device or interrupting the rinsing process. The structural design itself is optimized for maximum ease of use.

[0033] The following description provides specific application scenarios and requirements for this specification, intended to enable those skilled in the art to make and use the contents of this specification. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but rather to the widest scope consistent with the claims.

[0034] The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not restrictive. For example, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” used herein may also include the plural forms. When used in this specification, the terms “comprising,” “including,” and / or “containing” mean that the associated feature, integer, step, operation, element, and / or component is present, but do not preclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups, or that other features, integers, steps, operations, elements, components, and / or groups may be added to the system / method.

[0035] Considering the following description, these and other features of this specification, as well as the operation and function of the related components of the structure, and the economy of assembly and manufacture of the parts, can be significantly improved. All of these form part of this specification with reference to the accompanying drawings. However, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0036] The flowcharts used in this specification illustrate operations implemented according to some embodiments of this specification. It should be clearly understood that the operations in the flowcharts may not be implemented in a sequential order. Instead, the operations may be implemented in reverse order or simultaneously. Furthermore, one or more additional operations may be added to the flowcharts. One or more operations may be removed from the flowcharts.

[0037] In this specification, "X includes at least one of A, B, or C" means that X includes at least A, or X includes at least B, or X includes at least C. That is, X can include only one of A, B, and C, or any combination of A, B, and C, as well as other possible content / elements. Any combination of A, B, and C can be A, B, C, AB, AC, BC, or ABC.

[0038] In this specification, unless explicitly stated otherwise, the relationships between structures can be direct or indirect, complete or partial. For example, when describing "A is connected to B," unless explicitly stated that A and B are directly connected, it should be understood that A can be directly connected to B or indirectly connected to B. Similarly, when describing "A is above B," unless explicitly stated that A is directly above B (AB is adjacent and A is above B), it should be understood that A can be directly above B or indirectly above B (AB is separated by other elements, and A is above B). Furthermore, when describing "A is inside B," unless explicitly stated that A is entirely inside B, it should be understood that A can be entirely inside B or partially inside B. And so on.

[0039] Handheld spray guns are a common accessory in modern bathroom spaces, and their user experience directly impacts the cleaning experience. Currently, the mainstream handheld spray guns on the market are mainly divided into two structural designs: rocker button single-function spray guns and vertical center-button single-button spray guns. However, as users' demands for diversified rinsing scenarios and miniaturized products continue to increase, the existing structures have obvious technical shortcomings.

[0040] First, most existing spray guns suffer from limited functionality. Traditional products, such as rocker-button single-function spray guns, only support one water flow mode in their internal flow channels, failing to meet the diverse water flow requirements of different flushing scenarios. When users flush the toilet, clean the floor, or perform feminine hygiene, the required water flow intensity and coverage are different. A single-function spray gun cannot cover all bathroom flushing needs with a single device, limiting the product's versatility and reducing the user experience.

[0041] Secondly, there is an irreconcilable contradiction between the labor-saving operation structure and the appearance design of traditional spray guns. Rocker button spray guns rely on an exposed rocker structure to achieve labor-saving pressing, but this structure greatly limits the appearance design: on the one hand, the assembly gap between the exposed rocker and the housing is prone to trapping dirt and bacteria in the humid environment of the bathroom, which not only reduces the hygiene of the product but also increases the difficulty of cleaning and maintenance; on the other hand, this relatively large external component also limits the product's ability to be designed in a simple and integrated direction, affecting the overall aesthetics of the product.

[0042] While the vertical center-bolt single-button spray gun solves the problem of dirt accumulation on exposed rocker plates, its internal structure introduces new design bottlenecks. This solution uses a vertical center-bolt as the core of water flow control, and its axially arranged structure requires sufficient longitudinal assembly space within the spray gun housing to accommodate the center-bolt and related components such as springs and seals. This directly leads to an increase in the overall outer diameter and length of the spray gun, failing to meet the current trend of miniaturization and lightweight spray guns.

[0043] The bathroom fixtures industry is currently moving towards modularization and minimalist integrated solutions, with multifunctional, compact, and miniaturized hardware accessories becoming the mainstream of research and development. Existing spray gun structures suffer from inherent defects due to excessive internal space occupation, which has become a key technical obstacle restricting product iteration and upgrades. There is an urgent need for a new spray gun solution that can simultaneously achieve independent control of dual water channels, has a compact structure, and a simple appearance, thus addressing the pain points of existing products.

[0044] As an example, Figure 1 An exploded view of the structure of a water path switching device 100 and a flushing spray gun provided according to an embodiment of the present disclosure is shown.

[0045] Firstly, referring to Figures 2 to 5This disclosure provides a waterway switching device 100 for switching the connection state between the main waterway 111 and different branch waterways, including: The main body 110 has the main waterway 111 and two branch waterways, wherein the main waterway 111 is capable of communicating with the two branch waterways; The switching component 120 includes a first switching part 121, a balancing elastic element 122 and a second switching part 123 disposed within the main body 110. The balancing elastic element 122 is located between the first switching part 121 and the second switching part 123 and is used to reset the first switching part 121 and the second switching part 123. The first control component 130 is installed on the main body 110 and is directly or indirectly connected to the first switching unit 121; The second control component 140 is installed on the main body 110 and is directly or indirectly connected to the second switching unit 123; The switching component 120 is normally closed. Under normal conditions, the main waterway 111 and the two branch waterways are simultaneously closed. When the first control component 130 is driven, it causes the first switching part 121 to move toward the second switching part 123, and the main waterway 111 and one of the two branch waterways are switched from a closed state to a connected state. After the first control component 130 is driven to terminate, the balance elastic element 122 resets the first switching part 121. When the second control component 140 is driven, it causes the second switching part 123 to move toward the first switching part 121, and the main waterway 111 and the other of the two branch waterways switch from a closed state to a connected state. After the first control component 130 is driven to terminate, the balancing elastic element 122 resets the second switching part 123.

[0046] The aforementioned waterway switching device 100 (hereinafter referred to as the device) is a coordinated arrangement of the main waterway 111 and two branch waterways. Specifically, the main body 110 carries the main waterway 111 and the two branch waterways. This arrangement integrates and unifies the carriers of water flow, simplifies the overall size of the device, and makes the docking positions of different waterways more regular, reducing the risk of installation and docking deviations. The switching component 120 can arrange the first switching part 121, the balancing elastic element 122, and the second switching part 123 in sequence. The arrangement of the balancing elastic element 122 between the two switching parts can provide reset elasticity for both switching parts simultaneously, eliminating the need to configure reset elements for each switching part, reducing the number of parts, and compressing the internal space occupied by the device. The two control components (the first control component 130 and the second control component 140) are independently connected to the two switching parts (the first switching part 121 and the second switching part 123), ensuring that the switching control of the two waterways does not interfere with each other, avoiding the false triggering problem that is prone to occur in single control structures, and improving the reliability of the switching action.

[0047] The normally closed configuration combined with dual-control independent drive makes the device more suitable for the actual needs of water outage standby: it does not require additional driving force to maintain the closed state, there is no additional energy consumption in standby mode, and it will not accelerate component aging due to continuous force. The action combination of the first control component 130 driving the first switching part 121 to move towards the second switching part 123 to open one side of the water channel, and the second control component 140 driving the second switching part 123 to move towards the first switching part 121 to open the other side of the water channel, relies on the opposing movement of the two switching parts to achieve the opening of a single water path. It does not require additional multi-path independent blocking structures, the action logic is simpler, and the probability of jamming failure is lower. The combination configuration of the balancing elastic element 122 between the two switching parts, when one side of the switching part is activated, the elastic force of the elastic element can also help stabilize the position of the other side of the switching part, preventing unrelated water paths from being accidentally connected.

[0048] The above-mentioned complete set of devices can achieve the function of independent switching between two water channels with fewer parts, and the overall structure is more compact, making it suitable for installation in water channel scenarios with limited space; the dual independent control supports opening any one water channel as needed, making it more flexible to use; the normally closed plus elastic reset design reduces ineffective energy consumption and component wear, resulting in a longer overall service life of the device and lower failure maintenance costs.

[0049] In summary, the water circuit switching device 100 disclosed herein, through the structural design of integrating the main and branch water channels in the main body 110, clamping the balancing elastic element 122 in the dual switching parts, and independently driving the dual control components, simplifies the overall structure and reduces the number of parts, while achieving independent and reliable switching of the two water circuits. It also has the advantages of low standby power consumption, low failure rate, and long service life, and can be adapted to various application scenarios that require switching between different water circuits.

[0050] Reference Figure 6 and Figure 7 In some examples, the two water channels include a first water channel and a second water channel; The first switching unit 121 includes: The first guide portion 1211 is capable of extending into the first water distribution channel; The first sealing part 1212 is disposed on the periphery of the first guide part 1211 and is used to seal the first water channel; The first receiving part 1213 is connected to the first guiding part 1211 and located at the end of the first guiding part 1211. It is disposed on the outside of the first water channel and is used to receive the balancing elastic member 122.

[0051] The above structure divides the first switching part 121 into three independent functional structures: the first guide part 1211, the first sealing part 1212, and the first receiving part 1213. This structural division clarifies the functional boundaries of each unit: the first guide part 1211 alone undertakes the positioning and guiding role of extending into the water distribution channel. During the switching process, the first guide part 1211 first enters the water distribution channel to complete positioning calibration, preventing the first sealing part 1212 and the overall structure from deviating or getting stuck. The push stroke always advances smoothly along the axis of the water distribution channel, reducing the resistance of the switching operation and structural wear; the first sealing part 1211... 12. Based on the peripheral positioning arrangement of the guide part, it can accurately reach the sealing position by following the guide part, ensuring that the peripheral part fully fits the inner wall of the water channel, achieving reliable on / off sealing, and will not cause leakage due to positioning deviation; the first receiving part 1213 is set on the outside of the water channel, which will not occupy the water passage space inside the water channel, avoid additional water resistance affecting the flow efficiency, and also provide a stable support receiving point for the balancing elastic element 122. The expansion and contraction force of the elastic element is always transmitted along the preset direction, and will not be affected by the impact of water flow in the water channel, thus greatly improving the stability of the force.

[0052] It should be noted that the size of the first guide section 1211 is smaller than the size of the corresponding water channel, so that the water channel can be opened after the first switching section 121 is driven to move, thus opening the corresponding water passage. After the driven state is released, the balancing elastic member 122 will reset the first switching section 121 and re-close the corresponding water channel. The second guide section 1231 is similar and will not be described in detail later.

[0053] Reference Figure 6 and Figure 7 In other examples, the second switching unit 123 includes: The second guide section 1231 is capable of extending into the second water channel; The second sealing part 1232 is disposed on the periphery of the second guide part 1231 and is used to seal the second water channel; The second receiving part 1233 is connected to the second guide part 1231 and located at the end of the second guide part 1231. It is disposed on the outside of the second water channel and is used to receive the balancing elastic member 122.

[0054] The second switching unit 123 is similar to the first switching unit 121, except that it controls the opening and closing of different water channels. Specifically, through the cooperation of the second guide unit 1231, the second sealing unit 1232, and the second receiving unit 1233, the beneficial effects obtained are the same as those of the first switching unit 121. The second guide unit 1231 extends into the water channel in advance to complete the guidance and positioning, ensuring the positioning accuracy of the second switching process and avoiding jamming; the second sealing unit 1232 accurately seals the water channel based on the positioning around the guide unit, ensuring the reliability of the seal; the second receiving unit 1233 supports the balancing elastic member 122 on the outside without occupying the internal water passage space, while ensuring the stability of the elastic member under force, providing consistent structural stability for the switching action of the two water channels.

[0055] The first switching part 121 and the second switching part 123 mentioned above adopt a isomorphic combination design of guiding, sealing and external support, which reduces the processing complexity of the overall structure. The structural specifications of the two switching parts can be designed and produced in a unified manner, which reduces the types of parts and processing steps, and reduces the production and manufacturing costs and the cost of replacing parts for later maintenance. The two switching components each correspond to an independent water channel, and each completes the on / off switching action of its corresponding water channel. That is, when either side of the control component is pressed once, only the water channel matched with that control component is opened, while the other water channel remains closed, and the two switching paths do not interfere with each other. In addition, both switching parts provide support for the balancing elastic element 122 through the outer receiving part. The two switching parts can be symmetrically arranged on both sides of the balancing elastic element 122, resulting in a more balanced overall force distribution. This can offset the structural off-center load caused by unilateral elastic force, further improve the operational stability of the entire switching valve assembly, and reduce the probability of structural deformation after long-term use.

[0056] The above-mentioned overall structure can adopt a modular structure with different functions, which greatly improves the structural compactness of the entire switching component 120. Each functional unit only undertakes its corresponding function, and there will be no functional redundancy. Only the necessary space for guidance and water passage is reserved inside the water channel, resulting in a smaller overall volume and adaptability to more water control scenarios with limited installation space. Meanwhile, the modular structure makes assembly, disassembly, and maintenance more convenient. When a structural part wears out or fails, only the damaged part needs to be replaced, without replacing the entire switching unit, resulting in lower maintenance costs. In addition, the dual switching unit design can adapt to the switching requirements of two independent water channels. The guide ensures the accuracy of the action, the seal ensures the reliability of water control, and the outer bearing ensures the stability of elastic force. The three links work together to improve the smoothness, sealing, and long-term stability of the entire water control switching process, thus extending the service life of the entire valve body.

[0057] In summary, this design divides the first and second switching sections 123 into three independent functional structures: guiding, sealing, and external support. Through clear structural division of labor, these structures respectively achieve smooth guidance and positioning, reliable sealing and closure, and stable support of elastic components, avoiding structural interference between different functions. The use of a homogeneous modular design reduces processing and maintenance costs while ensuring that the two switching sections operate independently and complementaryly, with balanced force. The overall design, while maintaining structural compactness, improves the reliability and stability of the dual-channel on / off switching, reduces production and maintenance costs, extends component lifespan, and adapts to water control switching requirements in various scenarios.

[0058] Reference Figure 6 and Figure 7 In some examples, the radial cross-section of the first sealing portion 1212 and / or the second sealing portion 1232 is at least partially tapered, and a tapered sealing surface is formed on the outer peripheral side.

[0059] The aforementioned conical sealing surface can better fit the mating sealing contact surface, adapt to the minor machining errors and assembly tolerances of the contact surface, thereby achieving a better sealing effect than conventional flat or curved surface structures. Under long-term pressure or temperature change conditions, it is also less prone to sealing failure due to structural deformation or material aging.

[0060] Furthermore, when used in conjunction with the balancing elastic element 122, the balancing elastic element 122 can continuously provide a stable preload to the conical sealing structure, compensate for the small gaps that occur after long-term use, and further improve the stability and service life of the sealing system.

[0061] In some examples, a first receiving portion 1213 is provided with a first snap-fit ​​groove 1214, and the first end of the balancing elastic member 122 snaps into the first snap-fit ​​groove 1214; The second receiving part 1233 is provided with a second snap-fit ​​groove 1234, and the second end of the balancing elastic member 122 is snapped into the second snap-fit ​​groove 1234.

[0062] The above structure can be provided with independent snap-fit ​​grooves in the two receiving parts, and the two ends of the balancing elastic element 122 are respectively embedded into the first snap-fit ​​groove 1214 and the second snap-fit ​​groove 1234 to complete the snap-fit ​​fixation. The above structure breaks down the elastic element that originally needed to be integrally formed or fixed by an additional connecting part 220 into an assembly form with snap-fit ​​at both ends, which simplifies the overall structural design, eliminates the need for additional pressure plates, bolts and other fixing parts, and reduces the structural complexity and overall space occupation.

[0063] During assembly, first align the first end of the balancing elastic element 122 with the first snap-fit ​​groove 1214 and push it in to snap it in place. Then align the second end with the second snap-fit ​​groove 1234 to complete the snap-fit. The assembly process is simple and clear, requiring only two steps of alignment and snap-fit ​​to complete the installation. There is no need for complicated alignment and locking operations, which reduces the assembly difficulty and improves the assembly efficiency. At the same time, the positioning method of snap-fit ​​at both ends can automatically limit the installation position of the balancing elastic element 122 and avoid misalignment during installation.

[0064] The locking method at both ends can stably constrain the balancing elastic element 122 in a preset position, reducing or even avoiding the displacement or loosening of the elastic element during operation, thus improving the overall working stability and reliability of the structure. At the same time, it simplifies the design of parts and assembly processes, reduces the overall production and assembly costs, and improves the mass production adaptability of the product.

[0065] In summary, by opening corresponding snap-fit ​​grooves in the first and second receiving parts 1233 respectively, and snap-fitting and fixing the two ends of the balancing elastic element 122, the overall structure is simplified and the assembly difficulty is reduced, while the fixing stability of the balancing elastic element 122 is effectively improved, which has the advantages of both production cost and performance.

[0066] It should be noted that the area where the switching component 120 is located can be enclosed to form a barrel-shaped structure in which the switching component 120 is nested. The corresponding inner wall can also further constrain the balancing elastic element 122, further reducing or even preventing the elastic element from shifting or loosening during operation.

[0067] Reference Figure 6 and Figure 7 In some examples, the first switching part 121 further includes a first reinforcing part 1216, which is disposed at the junction of the first receiving part 1213 and the first guide part 1211; The second switching part 123 also includes a second reinforcing part 1236, which is disposed at the junction of the second receiving part 1233 and the second guide part 1231.

[0068] The aforementioned first reinforcing part 1216 and second reinforcing part 1236 serve as incremental structures at corresponding junctions, directly filling the structural strength gaps at the connection points of the first receiving part 1213 and the first guide part 1211, and the second receiving part 1233 and the second guide part 1231. These two junctions are the core areas where the switching part withstands external impacts and stress concentration. The receiving part is responsible for bearing the action load transmitted by the trigger, and the guide part is responsible for providing directional constraints for the switching action. The connection point between these two is the weakest node in the entire force chain of the switching part. The reinforcing parts directly strengthen this weak node, achieving targeted reinforcement of the weak stress points from a structural layout perspective.

[0069] In the original structure without reinforcement, the first receiving part 1213 and the first guide part 1211, and the second receiving part 1233 and the second guide part 1231 are integrally formed different functional sections. The cross-sectional dimensions and structural support at the connection points are consistent with those of a single functional section. When the switching part repeatedly undergoes contact and triggers the actuator, the alternating load will continuously act on the connection point, and the stress will continuously concentrate in this area. After long-term use, stress fatigue, connection cracking, or even breakage are likely to occur. However, by placing reinforcement at the two connection points, the reinforcement can disperse the stress concentrated in this area and evenly transfer the load that was originally concentrated on the connection section to the entire switching part body, significantly reducing the alternating stress per unit area.

[0070] It should be noted that the aforementioned reinforcing structure can be multiple plate-like structures surrounding the corresponding guide portion, allowing for more uniform reinforcement.

[0071] Reference Figure 1 In some examples, the first control component 130 includes: The first pressing member 131 is movably connected to the main body 110. When driven, the first pressing member 131 can directly or indirectly press the first switching part 121. The first elastic element 132 has a first end connected to the first pressing element 131 and a second end connected to the main body 110 or the first switching part 121. The first elastic element 132 is used to drive the first pressing element 131 to reset. After being driven, the first pressing member 131 overcomes the elastic force of the first elastic member 132 and directly or indirectly drives the first switching part 121 to open the first water channel. And / or, the second control component 140 includes: The second pressing member 141 is movably connected to the main body 110. When driven, the second pressing member 141 can directly or indirectly press the second switching part 123. The second elastic element 142 has a first end connected to the second pressing element 141 and a second end connected to the main body 110 or the second switching part 123. The second elastic element 142 is used to drive the second pressing element 141 to reset. After being driven, the second pressing member 141 overcomes the elastic force of the second elastic member 142 and directly or indirectly drives the second switching part 123 to open the second water channel.

[0072] The above structure is a further refinement of the structure of the first control component 130 and the second control component 140. Specifically, the pressing component and the elastic component can be used as separate functional units, and then connected to the main body 110 and the switching part. The independent control of the two water channels is clearly defined at the structural level. Each control component corresponds only to its own switching part and will not interfere with each other, thus realizing the modular decomposition of the control link.

[0073] Existing integrated multi-channel control structures are prone to accidental triggering, where pressing one control component can cause an unexpected action in another switching unit. In contrast, this solution sets up the first and second control components 140 completely independently. Each component retains only a single-channel connection between the pressing element, the elastic element, and the corresponding switching unit, eliminating structural interference across components and preventing accidental triggering at its structural root. At the same time, the movable connection method provides the pressing element with room to move along the pressing direction, and the elastic element connects the pressing element and the fixed end (main body 110 / corresponding switching unit) respectively. This provides the pressing element with a resetting elastic constraint without restricting its triggering action.

[0074] The combination of the pressing element and the elastic element mentioned above realizes the triggering function and automatically completes the reset action. The combination of these elements can form three implementation methods. Specifically, it can be adapted to different water output demand scenarios as needed. It can either retain only a single-channel control or set up two independent channels at the same time, making it more adaptable.

[0075] When a user needs to open a water channel, they only need to apply pressure to the corresponding pressing element to overcome the elastic force of the elastic element and drive the switching part to open the channel. After releasing the pressing element, the accumulated elastic force of the elastic element can automatically drive the pressing element to reset, eliminating the need for the user to manually pull back the pressing element, thus simplifying the operation.

[0076] The above structure has a low barrier to entry; users only need to press to trigger it, and it automatically resets when released, resulting in a smoother user experience. The combination method is flexible, and single-channel or dual-channel control can be flexibly selected according to product needs. There is no need to redevelop the overall structure, which reduces the development and production costs of the product.

[0077] Furthermore, a sealing structure can be provided at the connection position between the first pressing member 131 and the second pressing member 141 and the main body 110 to prevent external water or dirt from entering the main body 110, ensuring the cleanliness of the main body 110 and preventing external contamination of the interior of the main body 110.

[0078] The first control component 130 and the second control component 140 mentioned above can adopt an asymmetrical back-to-back button layout that conforms to ergonomic design, supports one-handed operation and mode switching (different water output modes are achieved by applying force with different fingers), is comfortable to hold, easy to operate, and reduces the learning cost of use; Reference Figure 8 and Figure 9 In some examples, the first control component also includes: The first lever 133 is rotatably connected to the first pressing member 131 or the main body 110. The first lever 133 includes an integrally formed first rotating part 1331, a first driven part 1332 and a first driving part 1333. The first driven part 1332 and the first driving part 1333 are arranged at an angle.

[0079] The first torsion spring 134 is installed on the first rotating part 1331. The first force arm of the first torsion spring 134 acts on the first pressing member 131 or the main body 110, and the second force arm of the first torsion spring 134 acts on the first driven part 1332 or the first driving part 1333. When the first pressing member 131 is driven, it causes the first lever 133 to rotate relative to it, and drives the first switching part 121. The first torsion spring 134 is used to drive the first lever 133 to reset.

[0080] And / or, the second control component further includes: The second lever 143 is rotatably connected to the second pressing member 141 or the main body 110. The second lever 143 includes an integrally formed second rotating part 1431, a second driven part 1432 and a second driving part 1433. The second driven part 1432 and the second driving part 1433 are arranged at an angle. The second torsion spring 144 is installed on the second rotating part 1431. The second force arm of the second torsion spring 144 acts on the second pressing member 141 or the main body 110, and the second force arm of the second torsion spring 144 acts on the second driven part 1432 or the second driving part 1433. When the second pressing member 141 is driven, it causes the second lever 143 to rotate relative to it, and drives the second switching part 123. The second torsion spring 144 is used to drive the second lever 143 to reset.

[0081] The above structure is a further modification of the first and second control components. By adding two independent components—a lever and a torsion spring—more stable and reliable functions can be achieved. The lever includes three functional sections: a rotating part, a driven part, and a driving part. It can change the direction of the driven force, for example, converting radial force into axial force. A transmission and reset path can also be constructed through a rotational connection and torsion spring force application. This clearly defines three independent functional modules: pressing force, transmission reversal, and reset springback, avoiding structural interference caused by integrating multiple functions into a single part.

[0082] This structure places the pivot point on the rotating part of the lever. The driven part receives the pressing force from the pressing component, the driving part outputs torque to drive the switching part, and the torsion spring provides a separate reset force. Each component performs only its corresponding function, thus avoiding reliability issues caused by functional confusion from the structural source. If an integrated transmission and reset structure were used, a single component would need to perform three functions simultaneously: driven, transmission, and reset. This would not only significantly increase the complexity of component manufacturing but also accelerate component fatigue aging due to stress concentration in the deformation area.

[0083] Furthermore, the aforementioned first driven portion 1332 and first driving portion 1333 are arranged at an angle. This means that the first driven portion 1332 extends from the first end to the second end relative to the first rotating portion 1331 in a first direction, and the first driving portion 1333 extends from the first end to the second end relative to the first rotating portion 1331 in a second direction. The first direction and the second direction can intersect and have a certain angle, which can range from 30° to 180°. The angle in the attached figure is approximately 120°. It can also be 60°, 75°, 90°, 135°, 150°, 165°, etc. The angle can be adjusted adaptively according to the actual transmission requirements. The lengths of the first driven portion 1332 and the first driving portion 1333 can be equal or one longer than the other, and their ends can be curved to improve transmission efficiency.

[0084] The second driven part 1432 and the second driving part 1433 are set at an angle in a similar manner, and will not be described again here.

[0085] Furthermore, the first guide portion 1211 is provided with a first driven groove 1215 that matches the first driving portion 1333 in the first lever 133; the second guide portion 1231 is provided with a second driven groove 1235 that matches the second driving portion 1433 in the second lever 143. The rotation of the lever can cause the corresponding guide portion to slide relative to the main body 110.

[0086] Furthermore, the combination of the first elastic element 132 and the first torsion spring 134 in this disclosure can achieve dual reset, reduce the reset pressure of a single elastic element, increase service life, and reduce component costs.

[0087] Furthermore, the lever is a one-piece molded structure, which significantly reduces the difficulty of parts processing. Only the torsion spring mounting position and the rotation shaft position need to be reserved, resulting in low mold opening costs and high consistency in mass production. The structural fault tolerance is improved. If a single part is damaged, only the corresponding component needs to be replaced, without replacing the entire control assembly, resulting in lower maintenance costs. The functional partitions are clear, and the rotation connection provides a stable rotation fulcrum for the lever, avoiding lever offset and jamming during transmission, and resulting in higher transmission accuracy.

[0088] The aforementioned lever is a lever, which improves force transmission efficiency. The lever structure reduces the pressing stroke, allowing for a more compact overall structure and reducing the installation space occupied by the control components. It also improves reset stability, with a fixed torsion spring position and stable lever arm relationship. Even after long-term repeated pressing, there will be no issues with spring relaxation, misalignment, or detachment, resulting in a longer service life. Furthermore, it offers high flexibility in combination, adapting to various application scenarios such as single-switching and dual-switching, without requiring a redesign of the main 110 structure, thus reducing the development costs for products of different specifications.

[0089] In some examples, a balance bar 150 is provided on the first pressing member 131 and / or the second pressing member 141.

[0090] The aforementioned balance bar 150 is an additional structure directly mounted on the pressing component. It corrects the force offset generated during repeated pressing, ensuring the pressing component always moves in the preset direction and preventing misalignment or jamming between the pressing component and adjacent parts. This simplifies the design of additional correction structures. Derivation: During long-term use, the force points on the pressing component are prone to uneven distribution due to operational deviations. Unilateral force can cause the pressing component to tilt and jam. By directly mounting the balance bar 150 on the pressing component, the force can be balanced with the support of the bar, offsetting the deflection torque caused by unilateral force and structurally preventing tilting. Actual effect: It effectively improves the service life of the pressing component, reduces the probability of jamming during pressing, provides a smoother and more consistent user experience, and does not add excessive structural complexity, balancing user experience with ease of manufacturing and assembly.

[0091] Mounting slots are provided on both sides of the pressing component. The balance bar 150 has a U-shaped rod structure, with its middle part rotatably connected to the main body 110 and its two ends connected to the corresponding mounting slots. Specifically, the main body 110 is provided with a rotating connecting slot that matches the middle part of the balance bar 150. The middle part of the balance bar 150 can be snapped into the rotating connecting slot and has a certain rotation space. The mounting slots on both sides of the pressing component can limit and guide the two ends of the balance bar 150. The bent ends on both sides of the balance bar 150 can be inserted into the corresponding mounting slots and can slide relative to the mounting slots. When installing the balance bar 150, first remove the main body 110 of the pressing component from the assembly station. Check the position and dimensions of the mounting slots on both sides of the balance bar 150 and the pressing component. After confirming that the direction of the U-shaped opening is parallel to the movement direction of the pressing component, first insert one end of the balance bar 150 into one of the mounting slots and gently press it to make the end lock into the bottom of the slot. Then slightly adjust the angle of the bar and push the other end into the other mounting slot. After it is in place, gently shake the bar to confirm that both ends are not loose. If the design requires an interference fit, a small pressing tool can be used to press the end into the mounting slot to avoid deformation of the bar or damage to the slot caused by knocking. After installation, pull the pressing component back and forth several times in the preset direction to check for any jamming or movement deviation. Confirm that the balance bar 150 does not interfere with the movement of adjacent components, and the entire assembly process is complete.

[0092] In some examples, the two water channels are a shower water channel 112 and a blade water channel 113, with a shower structure 200 at the end of the shower water channel 112 and a blade water structure 300 at the end of the blade water channel 113.

[0093] The above-mentioned shower head structure 200 has a relatively dispersed water output and a wide coverage area, which can quickly wet and initially rinse a large area to be cleaned, removing floating dust and large particulate impurities attached to the surface.

[0094] The blade water structure 300 features concentrated water flow and stronger impact, allowing it to penetrate deep into crevices to flush away stubborn stains and effectively clean residual dirt that the shower head structure 200 struggles to remove.

[0095] The combination of two water outlet structures can balance cleaning efficiency and solve the problem of cleaning hard-to-reach areas. Compared with a single water outlet structure, it can complete high-quality cleaning in a shorter time and improve the overall user experience.

[0096] Furthermore, the water channel switching device 100 also includes a front water channel structure 160, a rear water channel structure 170, and a tail sleeve 180. The front water channel structure 160 and the rear water channel structure 170 are both located inside the main body 110, and the tail sleeve 180 is located at the end of the water inlet of the main body 110. The front water channel structure 160 and the rear water channel structure 170 are located at opposite ends of the switching assembly 120. The front water channel structure 160 cooperates with the main body 110 to form the aforementioned shower head water channel 112 and blade water channel 113, while the rear water channel structure 170 cooperates with the main body 110 to form the main water channel 111.

[0097] Furthermore, the shower head structure 200 includes a water outlet panel 210 at least partially located outside the main body 110 and a connector 220 disposed within the main body 110. The water outlet panel 210 is provided with a plurality of shower head outlets. The blade water structure 300 includes a front cover 310 at least partially located outside the main body 110 and a blade water outlet 320 disposed within the main body 110. The front cover 310 is provided with a blade water outlet adapted to the blade water outlet 320.

[0098] Secondly, this disclosure also provides a flushing spray gun, comprising: The water path switching device 100 described above can switch between the shower head water channel 112 and the blade water channel 113; Shower head structure 200, connected to shower head water channel 112; and The blade water structure 300 is connected to the blade water channel 113.

[0099] The flushing spray gun disclosed herein integrates the water path switching device 100 with the shower head structure 200 and the blade water structure 300 into one unit, fundamentally solving the pain point of traditional flushing equipment that requires multiple external water path interfaces and different water outlets to switch water output modes. In actual use, traditional flushing equipment often requires two separate water outlet devices or switching modes by disassembling and replacing water outlets if both gentle shower water output and high-pressure blade water output functions are needed. This process not only requires interrupting the current flushing operation, but also requires additional storage of the idle water outlet, wasting operation time and increasing storage space. For scenarios such as home cleaning, bathroom flushing, or car washing, the user experience is very unsmooth. However, this disclosure directly switches the internal water path on and off through the built-in water path switching device 100, without any external disassembly. Users only need to operate the switching device to change the water output mode in a short time (e.g., within 1-3 seconds). The entire process does not require taking your hands off the device or interrupting the flushing process. The structural design itself has been greatly optimized for ease of use.

[0100] Specifically, the reliability of this integrated structure far surpasses that of a split structure. Traditional split switching structures require sealing between multiple components. Each additional detachable connection point adds a potential point of leakage. Over time, the sealing rings at these connections wear out and age, leading to leaks that not only soil the environment but also reduce water pressure and affect rinsing performance. In contrast, the water switching device 100 disclosed in this invention is integrated within the spray gun. The shower head structure 200 and the blade water structure 300 are fixed structures on the spray gun body. The switching device controls the flow of water within the system, reducing the number of sealed interfaces and structurally lowering the probability of seal failure. This built-in switching structure also makes the spray gun's appearance more streamlined and integrated, eliminating protruding external interfaces and loose detachable parts. It provides a better grip, reduces dirt accumulation, and makes cleaning the spray gun easier, eliminating hard-to-reach areas.

[0101] The above-mentioned flushing spray gun can switch between two modes with one click: gentle water from the shower head and high-pressure water from the blade, meeting the flushing water needs of multiple bathroom scenarios and providing a better user experience. The above structure can eliminate the external rocker arm by incorporating a button structure in the main body along the 110-axis, making it more hygienic as there are no gaps for dirt to hide. At the same time, it removes the restrictions on the appearance of the shell, allowing for the design of a thin and minimalist appearance. The switching component 120 can be arranged axially based on the main body 110. Correspondingly, the first switching part 121, the balancing elastic element 122, and the second switching part 123 are all laid flat axially based on the main body 110, significantly reducing the overall size of the spray gun, achieving miniaturization and lightweight design, and adapting to the installation needs of modern minimalist bathrooms. The two water circuits are equipped with independent reset elastic elements such as springs, ensuring that the opening and closing of the water circuits do not interfere with each other. Pressing to reset is smooth, sealing prevents dripping, and the structure is durable and not prone to failure. Shower water and blade water can be switched separately. The integrated axial module is simple to assemble, with a compact component layout, facilitating mass production and effectively controlling product production costs. This disclosure simplifies the internal flow channel design, reduces the risk of leakage, and improves water inlet efficiency and outlet pressure. The dual-mode water output configuration covers diverse scenario needs, satisfying both the gentle water output requirements for daily rinsing and feminine hygiene, and the high-pressure cleaning needs for stubborn stains and crevices, making the product more adaptable.
