A water tank and sprayer for a toy sprayer

Abstract

This invention relates to the field of toy sprayer technology, and in particular to a water tank and sprayer for a toy sprayer. The tank includes a housing with an annular protrusion on the bottom wall for securing absorbent cotton. The side wall of the securing ring has a connecting groove. The tank also includes multiple sets of diversion plates, which are positioned between the inner side wall of the housing and the outer side wall of the securing ring. These diversion plates are staggered. Through this design, after liquid water enters the tank, it first gathers in the diversion space and then flows into the securing ring through the connecting groove. This reduces the flow distance of the water into the securing ring and improves the flow efficiency. As the water level in the diversion space rises, the water pressure increases, allowing the water to more easily flow into the securing ring through the connecting groove and contact the absorbent cotton. This enables even a small amount of water to generate sufficient pressure to pass through the connecting groove, allowing the sprayer to spray normally even with a small amount of water.

Description

Technical Field

[0001] This invention relates to the field of toy sprayer technology, and in particular to a water tank and sprayer for toy sprayers. Background Technology

[0002] With the development of technology and the increasing demands of children for the realism and fun of toys, toy design is constantly pursuing innovation and breakthroughs. In the toy market, a type of toy that simulates real spray is particularly popular among children. By adding a sprayer, spray toys can spray atomized gas, adding dynamic effects to the toys and making them more vibrant. Spray toys can bring children a brand-new interactive experience, enhance the fun of the toys, and stimulate children's desire to explore. For example, a fire-breathing dinosaur can spray mist combined with LED lights to simulate the fire-breathing effect of a dinosaur, and a steam train can spray steam to simulate real steam power. The existing sprayer includes a water tank, a top cover, absorbent cotton, and an atomizer. The water tank has an annular retaining ring for securing the absorbent cotton. Two sets of connecting grooves are located on the side wall of the retaining ring, both along the same diameter. The top cover is mounted on the water tank, and the atomizer is installed on the top cover to atomize the liquid from the absorbent cotton. The top cover has an inlet for adding liquid. When the toy is to activate the spray function, water needs to be added to the sprayer. Due to the surface tension of water, the interaction forces between water molecules cause the water to tend to form a spherical shape. The surface tension also creates resistance when the water passes through the connecting grooves. Therefore, after entering the water tank from the inlet, the liquid water flows around the retaining ring. Because of the small size of toy sprayers, it's impossible to reduce water flow resistance by increasing the width of the connecting groove. Furthermore, increasing the width of the connecting groove would reduce the contact area between the fixing ring and the absorbent cotton, causing the absorbent cotton to tilt and make poor contact with the atomizing plate, thus affecting the spraying effect. Therefore, existing atomizers require continuous water addition to raise the water level. Only when the water pressure exceeds the resistance can the liquid water pass through the connecting groove and contact the absorbent cotton. This design poses a safety hazard for children using the toy. To ensure proper spraying, children often add too much water. As the toy moves, excess water overflows the sprayer, causing a short circuit in the toy's internal circuitry and resulting in a poor user experience.

[0003] Therefore, there is a need to provide a water tank for a sprayer used in toys. Summary of the Invention

[0004] To address the problem in existing toy sprayers where, due to surface tension, insufficient water in the tank makes it difficult for the water to flow through the connecting groove and contact the absorbent cotton for atomization, resulting in a poor user experience, this application provides a water tank and sprayer for toy sprayers.

[0005] In a first aspect, the present invention provides a water tank for a toy sprayer, which adopts the following technical solution: A water tank for a toy sprayer includes a tank body, the bottom wall of which is provided with an annular protrusion for fixing a water-absorbing cotton, the side wall of which is provided with a communicating groove, and a plurality of diversion plates, the diversion plates being disposed between the inner side wall of the tank body and the outer side wall of the fixing ring, the diversion plates being staggered from each other.

[0006] Preferably, the diversion plate is provided in two sets, and the two sets of diversion plates are respectively connected between the inner side wall of the box and the outer side wall of the fixing ring to form a diversion space, and the connecting groove is connected to the diversion space.

[0007] Preferably, any one set of the drainage plates is inclined toward the other set of drainage plates so that the drainage space has a constricted portion, and the constricted portion is located near the opening of the connecting groove.

[0008] Preferably, the sidewall of the diversion plate gradually tapers upwards from the bottom wall of the box, so that the cross-section of the sidewall of the diversion plate is trapezoidal.

[0009] Preferably, the wall of any one set of connecting channels is inclined toward the wall of another set of connecting channels, so that the cross-section of the connecting channel is an inverted trapezoid.

[0010] Preferably, the distance between the diversion plate and the side wall of the connecting channel is L1, and the distance between the two side walls of the connecting channel is L2, where 0≤L1≤L2.

[0011] Preferably, the line connecting the center of the fixed ring and the center of the connecting groove is a radius R. When the diversion plate is projected onto the bottom wall of the box, the angle between the radius R and any set of diversion plates is α, where 0° < α < 180°.

[0012] Preferably, the side wall of the box is provided with an inclined portion that slopes from the outside in, and the inclined portion is provided corresponding to the drainage space.

[0013] Preferably, the inner sidewall of the box is provided with a slope, which gradually slopes from the connection between the sidewalls of the box and the bottom wall of the box.

[0014] Secondly, the present invention provides a technical solution for a toy sprayer that adopts the following: A sprayer for toys includes a water tank as described above, and also includes absorbent cotton, a top cover, and an atomizing plate. The top cover has an inlet for adding water into the tank and an atomizing port for connecting to a fixing ring. Two sets of drainage plates are respectively connected between the inner side wall of the tank and the outer side wall of the fixing ring to form a drainage space. The inlet connects to the drainage space. The absorbent cotton is inserted into the atomizing port and the fixing ring. The atomizing plate is disposed on the top cover and is used to atomize the liquid absorbed by the absorbent cotton.

[0015] The beneficial effects of this invention are as follows: 1. Through the design of the diversion plate, after liquid water enters the water tank, it first gathers in the diversion space, and then flows into the fixed ring through the connecting groove. This reduces the flow distance of the water into the fixed ring and improves the flow efficiency of the water. As the water level in the diversion space rises and the water pressure increases, the water can more easily flow into the fixed ring through the connecting groove and come into contact with the absorbent cotton. This allows a small amount of water to generate enough pressure to pass through the connecting groove, ensuring the contact area between the fixed ring and the absorbent cotton. This allows the sprayer to spray normally even with a small amount of water.

[0016] 2. Due to the improved water tank design, the amount of water added is reduced, thereby reducing the waiting time from adding water to spraying, improving the user experience for children. The improved design also reduces the risk of short circuits in the toy's internal circuitry caused by excessive water overflow, making the spray toy more convenient to use and improving the safety of the toy.

[0022] Furthermore, unless otherwise defined, the technical and scientific terms used in this invention have the same meanings as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for the purpose of describing particular embodiments only and not for limiting the invention. It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or collections thereof.

[0023] Example 1: Refer to Figures 1 to 4 A water tank for a toy sprayer includes a tank body 101. The bottom wall of the tank body 101 has an annular protrusion for fixing a water-absorbing cotton 2, and a fixing ring 102 for fixing the bottom wall. The side wall of the fixing ring 102 has a connecting groove 1021. The tank also includes two sets of diversion plates 103, which are disposed between the inner side wall of the tank body 101 and the outer side wall of the fixing ring 102. The two sets of diversion plates 103 are staggered, with at least two sets of diversion plates 103 corresponding to the connecting groove 1021. Due to the surface tension of water... The presence of water molecules causes them to tend to form a spherical shape due to intermolecular forces. Surface tension creates resistance as the water flows through the connecting channel 1021. Through the design of the guide plate 103, the liquid water, after entering the water tank 1, is blocked by the guide plate 103 and no longer flows around the fixing ring 102 of the absorbent cotton 2. The liquid water, blocked by the guide plate 103, collects at the guide plate 103. When the liquid water collects between the guide plates 103, and the water pressure exceeds the resistance of flowing through the connecting channel 1021, [the flow continues]. Water flows into the fixed ring 102 through the connecting groove 1021 and comes into contact with the absorbent cotton 2. Once the water comes into contact with the absorbent cotton 2, the absorbent cotton 2 absorbs the water, making it easier for the water to flow through the connecting groove 1021. Thus, when a small amount of water is added to the water tank 1, the absorbent cotton 2 can completely absorb the water and draw it to one end of the atomizing plate 4 for atomization. This allows the sprayer to spray normally with a small amount of water. Secondly, without increasing the width of the connecting groove 1021, spraying can be achieved with a small amount of water, ensuring the contact area between the fixed ring 102 and the absorbent cotton 2 and improving the stability of the absorbent cotton 2. Furthermore, atomized gas can be sprayed with only a small amount of water in the water tank 1, reducing the amount of water added and reducing the direction of liquid overflow from the sprayer causing short circuits to electronic components, thus improving the safety of using the spray toy. It also reduces the waiting time from adding water to spraying, improving the experience of children using the toy, bringing children a brand-new interactive experience, enhancing the fun of the toy, and stimulating children's desire to explore.

[0024] It is worth mentioning that in the existing sprayer, without the guide plate 103, water drips into the water tank 1 from the inlet 301 and flows around the absorbent cotton 2 fixing ring 102. When the water level does not exceed 2 / 3 of the absorbent cotton 2 fixing ring 102, the corresponding water volume is V1. It is difficult for water to flow into the absorbent cotton 2 fixing ring 102. Due to the poor water absorption effect of the absorbent cotton 2 on the side, it is difficult to spray smoke when the atomizing plate 4 is activated. However, in the improved sprayer, the water tank... 1 is equipped with a diversion plate 103. After the liquid water enters the water tank 1, it is blocked by the diversion plate 103 and no longer flows around the fixing ring 102 of the absorbent cotton 2. The liquid water is blocked by the diversion plate 103 and gathers at the diversion plate 103. When the liquid water gathers between the diversion plates 103 and the water pressure is greater than the resistance of the flow through the connecting channel 1021, the corresponding water volume is V2. The water flows into the fixing ring 102 through the connecting channel 1021 and contacts the absorbent cotton 2. V2 is much smaller than V1.

[0025] Reference Figure 1 To further ensure that spraying can be achieved with a small amount of water, it is necessary to allow the liquid water to flow more smoothly through the connecting groove 1021. Two sets of diversion plates 103 are provided. The two sets of diversion plates 103 are respectively connected between the inner side wall of the housing 101 and the outer side wall of the fixing ring 102 to form a diversion space 1031. The connecting groove 1021 is connected to the diversion space 1031. The sealed diversion space 1031 is designed to increase the water pressure. The connection between the connecting groove 1021 and the diversion space 1031 helps the water to pass better through the small opening of the connecting groove 1021, reduces the influence of water surface tension, and improves the smoothness of water flow. By improving the water flow conditions, the water volume requirement of the sprayer is reduced.

[0026] When the water overflows the inner wall of the drainage space 1031, the water will overflow from the top wall of the drainage plate 103 into another part of the box 101. Two sets of connecting channels 1021 are provided, and the two sets of connecting channels 1021 are arranged opposite each other. After the water drainage space 1031 overflows, the opposite connecting channels 1021 can make the water flow into the fixed ring 102 from two opposite directions, increasing the fluidity of the water during the flow process and reducing the flow resistance. Secondly, the opposite connecting channels 1021 can provide a more stable water supply, making the spray effect more stable. It is worth mentioning that the height of the drainage plate 103 is greater than or equal to the height of the fixed ring 102.

[0027] Since the absorbent cotton 2 expands slightly in volume after absorbing water, the side wall of the fixing ring 102 gradually expands upward from the bottom wall of the housing 101, making the side wall of the fixing ring 102 narrower at the top and wider at the bottom. The cross-section of the side wall of the fixing ring 102 is trapezoidal, and the inner diameter of the bottom of the fixing ring 102 is larger than the inner diameter of the top of the fixing ring 102. Before absorbing water, the top of the fixing ring 102 contacts the absorbent cotton 2 to fix its insertion position. When the absorbent cotton 2 expands after absorbing water, the bottom wall of the fixing ring 102 provides space for the absorbent cotton 2 to expand, so that the expanded absorbent cotton 2 contacts the bottom wall of the fixing ring 102, increasing the contact area between the absorbent cotton 2 and the fixing ring 102, making the absorbent cotton 2 more securely inserted in the fixing ring 102.

[0028] Reference Figures 1 to 3 To further improve the smoothness of water flow from the drainage space 1031 into the connecting channel 1021, one set of drainage plates 103 is inclined towards the other set of drainage plates 103, giving the drainage space 1031 a constricted portion. The constricted portion is located near the opening of the connecting channel 1021. This makes the two sets of drainage plates 103 form a V-shape. The constricted portion allows the water in the drainage space 1031 to flow more concentratedly into the connecting channel 1021, increasing the guidance of the water flow, reducing water scattering and resistance, reducing water bends and collisions, and lowering water flow resistance, making the water flow smoother. Secondly, due to the constricted portion design of the drainage space 1031, the water concentration effect is increased, the water pressure is increased, and it helps the water to better enter the fixing ring 102 through the narrow opening of the connecting channel 1021.

[0029] Reference Figures 1 to 3 The sidewall of the diversion plate 103 gradually expands upward from the bottom wall of the box 101, thus making the cross-section of the sidewall of the diversion plate 103 trapezoidal. The distance between the outer surface of the top wall of the diversion plate 103 and the inner surface of the bottom wall of the box 101 is greater than the height of the connecting channel 1021, which improves the water flow distribution. Under the action of its own weight, the water slides down the sidewall of the diversion plate 103 to the bottom wall of the diversion space 1031, reducing the amount of water adhering to the sidewall of the diversion plate 103. Secondly, the gradually expanding sidewall design of the diversion plate 103 makes the inner wall of the diversion space 1031 have an inverted frustum shape, which increases the water flow concentration effect, increases the water pressure in the diversion space 1031, and helps the water to pass through the connecting channel 1021 better and be atomized. Furthermore, it reduces the diffusion of the water flow, making the water flow more concentrated towards the connecting channel 1021, and improving the diversion efficiency of the diversion space 1031.

[0030] Reference Figure 4The wall of any one set of connecting channels 1021 is inclined toward the wall of another set of connecting channels 1021, so that the cross-section of the connecting channel 1021 is set in an inverted trapezoidal shape. The width of the opening of the connecting channel 1021 near the bottom of the box 101 is smaller than the width of the opening of the top wall of the connecting channel 1021. Due to the water pressure in the drainage space 1031, the pressure near the bottom of the box 101 is greater than the pressure at the upper end of the drainage space 1031, so that the water pressure matches the opening size of the connecting channel 1021, improving the smoothness and consistency of the water flow through the connecting channel 1021.

[0031] Reference Figure 3 When the diversion plate 103 is connected to the side wall of the connecting channel 1021, if the distance between the side plate of the diversion plate 103 and the inner wall of the connecting channel 1021 is too large, water will accumulate at the connection between the diversion plate 103 and the fixing ring 102, forming water droplets or beads, which are in equilibrium and have poor flow, preventing water from flowing normally into the connecting channel 1021. Conversely, if the distance between the side wall of the diversion plate 103 and the connecting channel 1021 is too small, the diversion plate 103 will occupy the width of the opening of the connecting channel 1021, increasing the resistance to water flow. The distance between the diversion plate 103 and the side wall of the connecting channel 1021 is L1, and the distance between the two side walls of the connecting channel 1021 is L2, where 0 ≤ L1 ≤ L2. It should be noted that when the diversion plate 103 is connected to the side wall of the connecting channel 1021, the water will accumulate at the connection between the diversion plate 103 and the fixing ring 1021, forming water droplets or beads, which are in equilibrium and have poor flow, preventing water from flowing normally into the connecting channel 1021. When the sidewall of the flow plate 103 gradually tapers upwards from the bottom wall of the housing 101, thus making the cross-section of the sidewall of the flow plate 103 trapezoidal, L1 represents the minimum distance between the flow plate 103 and the sidewall of the connecting channel 1021. When the channel wall of any one set of connecting channels 1021 is inclined toward the channel wall of another set of connecting channels 1021, thus making the cross-section of the connecting channel 1021 inverted trapezoidal, L2 represents the minimum distance between the two sidewalls of the connecting channel 1021. It is worth mentioning that when the distance between the two sidewalls of the connecting channel 1021 is 2mm, the distance between the flow plate 103 and the sidewall of the connecting channel 1021 is 0.92mm, which improves the flow efficiency and smoothness of the water flow.

[0032] Reference Figure 3After determining the distance between the diversion plate 103 and the inner wall of the connecting channel 1021, the factor affecting the volume of the diversion space 1031 is the setting angle of the diversion plate 103. The size of the diversion space 1031 plays a decisive role in the water pressure. If the diversion space 1031 is too small, the water pressure will be too low and unable to overcome the resistance of the water flow through the connecting channel 1021. If the diversion space 1031 is too large, it will increase the amount of water added, V2. The line connecting the center of the fixing ring 102 and the center of the connecting channel 1021 is the radius R. When the diversion plate 103 is projected onto the bottom wall of the box 101, the angle between the radius R and any set of diversion plates 103 is α, where 0° < α < 180°. When the distance between the side wall of the box 101 and the outer wall of the fixing ring 102 is large, the angle will be smaller. When angle α is close to 0°, the volume of the drainage space 1031 can be increased by tilting the drainage plate 103 at a small angle, thereby obtaining water pressure sufficient to overcome the resistance of water flowing through the connecting channel 1021. When the distance between the side wall of the tank 101 and the outer wall of the fixing ring 102 is small, the clamping angle α is close to 180°. At this time, a larger tilt angle is needed to increase the volume of the drainage space 1031, thereby obtaining water pressure sufficient to overcome the resistance of water flowing through the connecting channel 1021. It is worth mentioning that when the distance between the side wall of the tank 101 and the outer wall of the fixing ring 102 is 1.5cm, the included angle α is 27.5°, the included angle between the two sets of drainage plates 103 is 55°, and the extension line of the angle bisector of the two sets of drainage plates 103 passes through the center of the fixing ring 102.

[0033] Reference Figures 1 to 4 The side wall of the box 101 is provided with an inclined part 104 that slopes from the outside to the inside. The inclined part 104 is provided in the corresponding drainage space 1031. After the liquid enters the drainage space 1031, the water level will rise continuously as the water volume increases. The water is diverted to the connecting channel 1021 by the inclined part 104 that faces the connecting channel 1021, thus optimizing the drainage effect. Furthermore, when the water drips onto the inclined part 104, the water flows along the side wall of the drainage plate 103 to the bottom wall of the box 101.

[0034] It is worth mentioning that the side wall of the box 101 of the inclined part 104 is arc-shaped, and the center of the side wall is concentric with the center of the fixed ring 102, forming a force on the liquid ring in the drainage space 1031, so that the water in the drainage space 1031 flows more smoothly to the connecting groove 1021.

[0035] Reference Figure 1 The inner side wall of the box 101 is provided with a slope 105. The slope 105 is gradually inclined from the connection with the side wall of the box 101 toward the bottom wall of the box 101 to reduce the flow resistance of the liquid in the box 101 and make the flow smoother.

[0036] The side wall of the housing 101 is provided with an inwardly protruding part, which is arc-shaped and serves to buffer the water flow. Furthermore, the inwardly protruding part makes the side wall of the housing 101 form a concave part, which facilitates the installation of the sprayer.

[0037] Example 2: Refer to Figures 1 to 10 A sprayer for toys includes a water tank as described in Embodiment 1, and also includes absorbent cotton 2, a top cover 3, and an atomizing plate 4. The top cover 3 has an inlet 301 for adding water into the tank body 101 and an atomizing port 302 for connecting to a fixing ring 102. The inlet 301 connects to a drainage space 1031, and the atomizing port 302 connects to the fixing ring 102. The absorbent cotton 2 is inserted into the atomizing port 302 and the fixing ring 102. The atomizing plate 4 is disposed on the top cover 3 and is used to atomize the liquid absorbed by the absorbent cotton 2. The inlet 301 is used to add liquid water. The top cover 3 is assembled with the water tank 1 to form a sealed water storage space, preventing the risk of liquid overflow from the sprayer causing short circuits in the components. By using the top cover 3 to cover the water tank 1, the spraying speed is reduced. The difficulty in processing the components of the misting device improves the assembly effect of the spray. The atomizing plate 4 is assembled on the upper cover 3. When in use, water is added through the water inlet 301. The water enters the drainage space 1031. As the amount of water increases, the water level in the drainage space 1031 rises and the water pressure increases. When the water pressure is greater than the resistance of the water flow through the connecting groove 1021, the water flows from the drainage space 1031 into the fixing ring 102 and contacts the absorbent cotton 2. After the absorbent cotton 2 absorbs water, the atomizing plate 4 converts the liquid into tiny mist particles. When the misting device is applied to toys, it creates a spray effect. For example, when the misting device is applied to a fire-breathing dinosaur toy, it can simulate the phenomenon of the dinosaur breathing fire. When the misting device is applied to a steam train toy, it can simulate the steam of a steam engine.

[0038] Reference Figure 9 When the atomizing plate 4 is assembled with the upper cover 3, the upper cover 3 is provided with a placement groove 303 for placing the atomizing plate 4. The placement groove 303 is recessed from the outer top wall of the upper cover 3 downwards. The placement groove 303 improves the stability of the atomizing plate 4 assembly position, improves the integrity of the sprayer, reduces the risk of the atomizing plate 4 being misaligned, and improves the spraying effect and uniformity of the sprayer. Reference Figure 9 The arrangement of the atomizing port 302 and the atomizing plate 4 affects whether the absorbent cotton 2 can continuously deliver water from the water tank 1 to the atomizing plate 4 for atomization. The opening of the atomizing port 302 is connected to the bottom wall of the placement groove 303. It is worth mentioning that the center of the atomizing port 302 coincides with the center of the placement groove 303. The absorbent cotton 2 passes through the atomizing port 302, and the bottom surface of the atomizing plate 4 contacts the inner bottom wall of the placement groove 303, thereby contacting the absorbent cotton 2 and atomizing the water absorbed by the absorbent cotton 2.

[0039] Reference Figures 5 to 7After the water in the water tank 1 is absorbed by the absorbent cotton, it will cause an imbalance in the pressure inside the water tank 1. The top cover 3 is also provided with an exhaust hole 304, which is connected to the water tank 1. The exhaust hole 304 is used to balance the internal and external pressure, so that the absorbent cotton 2 can continuously absorb the water in the water tank 1, thereby the atomizing plate 4 can continuously generate mist, improve the realism of the toy's air jet, and increase the toy's interactivity and fun.

[0040] When the inner wall of the drainage space 1031 is projected onto the top cover 3, the drainage space 1031 and the vent 304 are staggered, so that the drainage space 1031 can maintain a certain water pressure, allowing the water in the drainage space 1031 to flow smoothly into the fixing ring 102. If the vent 304 is aligned with the drainage space 1031, the drainage space 1031 will be depressurized, affecting the water flow to the fixing ring 102. As a result, the atomizing plate 4 cannot continuously and stably output atomized gas, causing the toy to spray intermittently, which affects the child's user experience.

[0041] Reference Figures 7 to 9 The absorbent cotton 2 is inserted into the atomizing port 302 and the fixing ring 102. With the increase of usage time and frequency, the absorbent cotton 2 will shrink to a certain extent, which will reduce the contact area between the absorbent cotton 2 and the atomizing plate 4 or prevent them from contacting each other. This will cause the sprayer to fail to spray atomized gas normally. Therefore, a sprayer for toys also includes a compression spring 5. The two ends of the compression spring 5 are connected between the absorbent cotton 2 and the bottom wall of the water tank 1. Under the elastic force of the compression spring 5, the absorbent cotton 2 is squeezed towards the atomizing plate 4, so that the absorbent cotton always sticks to the atomizing plate 4, thereby the sprayer continuously and stably outputs atomized gas, improves the service life of the sprayer, and improves the spraying effect and spraying continuity of the spraying toy.

[0042] Reference Figures 5 to 9 When a compression spring 5 is provided between the absorbent cotton 2 and the bottom wall of the water tank 1, the compression spring 5 indirectly exerts a pushing force on the atomizing plate 4, causing the atomizing plate 4 to tend to move away from the top cover 3. Obviously, when the inner wall of the placement groove 303 is engaged with the outer wall of the atomizing plate 4, under the action of the compression spring 5, there is a risk that the atomizing plate 4 will detach from the placement groove 303 and thus detach from the top cover 3. Therefore, a sprayer for toys also includes a clamping member 6 for pressing the atomizing plate 4. The clamping member 6 is screwed to the top cover 3. The clamping member 6 presses the atomizing plate 4 onto the top cover 3, providing a downward force for the atomizing plate 4, while the compression spring 5 provides an upward force for the absorbent cotton 2, thereby making the absorbent cotton 2 adhere tightly to the atomizing plate 4, improving the atomization effect and spray continuity of the sprayer.

[0043] Reference Figures 5 to 7 In order to ensure that the mist can be emitted normally after the clamping component 6 is installed, the clamping component 6 is provided with a mist outlet 601, which is connected from the outer top wall of the clamping component 6 toward the atomizing plate 4.

[0044] Reference Figures 5 to 7 In order to guide the sprayed atomized gas, the clamping member 6 has a protruding guide port 602. The guide port 602 is annular. The mist outlet 601 is tangent to the guide port 602. The inner diameter of the guide port 602 is larger than that of the mist outlet 601, which increases the cross-sectional area and reduces the flow rate of the atomized gas. The atomized gas does not need as much kinetic energy to maintain its flow, thereby forming a fan-shaped atomization effect and improving the realism of the spray toy.

[0045] Reference Figures 5 to 7 To further enhance the realism of the toy, the recessed part 603 is recessed on the side from the guide port 602 toward the atomizing port 302 and is used to install LED lights. The recessed part 603 is arc-shaped, making the guide port 602 crescent-shaped. By changing the color of the LED lights, the effect of shooting fire or air can be simulated, thus enhancing the realism of the spray toy. The crescent-shaped guide port 602 places the LED in the fan-shaped atomized gas, improving the uniformity of the LED illuminating the atomized gas.

[0046] Reference Figures 7 to 10 To further enhance the stability of the absorbent cotton 2, a positioning ring 305 for fixing the absorbent cotton 2 is provided on the inner wall of the top cover 3 protruding towards the fixing ring 102. The positioning ring 305 is concentrically arranged with the fixing ring 102, thereby reducing the risk of the absorbent cotton 2 deforming under the elastic force of the compression spring 5.

[0047] It is worth mentioning that the height of the positioning ring 305 is less than the distance between the top wall of the fixing ring 102 and the inner top wall of the upper cover 3, allowing water to come into contact with the absorbent cotton 2 through the gap, increasing the water absorption of the absorbent cotton 2, thereby enabling the sprayer to continuously output atomized gas. The height L3 of the positioning ring 305 and the distance L4 between the top wall of the fixing ring 102 and the inner top wall of the upper cover 3 are L4-L3=0.5mm±0.2mm, preferably L4-L3=0.3mm. Under normal temperature and pressure, the diameter of a water droplet is about 0.3 mm. This range is derived from physical factors such as the size of the water droplet and surface tension. By setting L4-L3=0.3mm, water can flow normally through this gap and come into contact with the absorbent cotton 2, while ensuring that the contact area between the positioning ring 305 and the absorbent cotton 2 is maximized.

[0048] Reference Figure 2 and Figure 7The height of the diversion plate 103 affects the volume of the diversion space 1031, thereby affecting the water pressure in the diversion space 1031. The height of the diversion plate 103 is greater than the height of the fixing ring 102. An overflow groove 1033 is provided on the side of the diversion plate 103 near the positioning ring 305. Preferably, the sum of the height of the fixing ring 102 and the distance between L4 and L3 is less than the height of the diversion plate 103. When the water in the diversion space 1031 overflows the overflow groove 1033, the water overflows from the diversion space 1031 into the housing 101. The overflow groove 1033 is set near the gap between the positioning ring 305 and the fixing ring 102, so that while overflowing, some water flows into the gap and contacts the absorbent cotton 2, so that the absorbent cotton 2 has a better water absorption effect and improves the spray continuity and consistency of the sprayer.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
