Description

Water gun connector with microbubble generating structure Technical Field

[0001] This utility model belongs to the field of microbubble technology for household cleaning equipment, and specifically relates to a water gun connector with a microbubble generating structure. Background Technology

[0002] Microbubbles are bubbles with diameters ranging from tens of micrometers to hundreds of nanometers when they are generated. These bubbles are between microbubbles and nanobubbles and have physical and chemical properties that conventional bubbles do not possess. They can be used in household cleaning scenarios, including laundry and dishwashing.

[0003] In related technologies, the generators that produce microbubbles are relatively large and not suitable for household appliances that are directly connected to tap water pipes. If the generator is directly connected to the water gun, it not only increases the overall length of the connection between the water gun and the water supply hose, but also changes the center of gravity of the water gun, making it inconvenient for users to hold the water gun and continue rinsing, resulting in a decline in the user experience.

[0004] Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a water gun connector with a microbubble generating structure. This solves the problem that the existing microbubble water generating devices occupy a large space, and directly connecting the generator to the water gun changes the center of gravity of the water gun, making it inconvenient for users to hold the water gun and continue rinsing, thus reducing the user experience.

[0020] In one embodiment of this utility model, the inner wall of the water outlet connection is provided with a stepped structure, which is used to form a sealed cavity when connected with the water gun.

[0021] In one embodiment of this utility model, an elastic element is provided between the outer shell and the water outlet connection part. One end of the elastic element is abutted at the connection between the water outlet connection part and the water inlet connection part, and the other end of the elastic element is abutted at the top of the guide slider, so as to keep the buckle structure formed by the buckle in a locked state.

[0031] The water gun connector with a microbubble generating structure provided by this utility model can achieve the following technical effects:

[0032] 1. This utility model integrates the inlet hurricane plate, outlet hurricane plate, and inner core in a single molding process, achieving the integration of the microbubble generating structure and the water gun connector. This avoids occupying additional installation space and achieves the beneficial effects of both microbubble generation and easy installation. It also avoids increasing the overall length of the water gun connection to the water supply hose, which would alter the water gun's center of gravity, making it easier to hold the water gun for rinsing and other operations. The principle behind generating microbubbles is as follows: the flow velocity of the water passing through the water gun connector of this utility model rapidly changes to a turbulent state. In this turbulent state, the water not only collides within the inner cavity of the inlet connection but also collides a second time with the sealed cavity inside the outlet connection as it flows out from the multiple bubble generating holes of the outlet hurricane plate. This effectively microbubbles the bubbly or dissolved air in the tap water.

[0033] 2. By installing a conversion connector in the guide connector inside the water inlet connection, the conversion connector includes a sleeve, which facilitates the installation and replacement of conversion connectors of different thicknesses and sizes by means of a sleeve. This allows the water gun connector of this utility model to adapt to different water gun water supply hose connections, increasing the versatility of the water gun connector, and it has the characteristics of simple operation and high flexibility.

[0034] 3. During the installation process of the threaded connector by rotating it along the thread direction, the inside of the threaded connector abuts against the outer end of the water inlet connection, causing the outer end of the water inlet connection to close towards the water inlet connection, thereby clamping and fixing the water supply hose located between the water inlet connection and the guide connector, which facilitates the installation and adjustment of the water supply hose; and, by providing several flanges on the outer surface of the sleeve, not only can the structural strength of the guide connector be enhanced, but the contact part between the water supply hose and the sleeve can also be deformed by the flanges, which enhances the sealing effect of the connection.

Detailed Implementation

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] Example 1

[0048] Referring to Figures 1-4, one embodiment of this utility model provides a water gun connector with a microbubble generating structure, including an inner core 1, a threaded connector 2, a housing 3, and a conversion connector 4. The inner core 1 includes an inlet connection 11 and an outlet connection 12. The threaded connector 2 is threadedly connected to the outside of the inlet connection 11. The housing 3 is slidably disposed on the outside of the outlet connection 12. The outlet connection 12 is connected to the water gun via a snap-fit ​​structure. A guide connector 13 is provided inside the inlet connection 11. An inlet hurricane plate 5 is provided at the end of the guide connector 13. An outlet hurricane plate 6 is provided at the connection between the inlet connection 11 and the outlet connection 12. The conversion connector 4 is sleeved on the outside of the guide connector 13. The inlet hurricane plate 5 and the outlet hurricane plate 6 are integrally formed with the inner core 1. Both the inlet hurricane plate 5 and the outlet hurricane plate 6 are provided with a plurality of bubble generating holes 7. An inner cavity 14 is formed at the center of the inner core 1.

[0049] In this embodiment, the present invention integrates the inlet hurricane plate 5, the outlet hurricane plate 6, and the inner core 1 in a single molding process, achieving the integration of the microbubble generating structure and the water gun connector. This avoids occupying additional installation space and achieves the beneficial effects of generating microbubbles and convenient installation. It also avoids the change in the center of gravity of the water gun caused by increasing the overall length of the connection between the water gun and the water supply hose. The principle behind this is as follows: the flow velocity of the water flowing through the water gun connector of the present invention is rapidly changed into a turbulent state. The turbulent water not only collides in the inner cavity 14 of the inlet connection part 11, but also collides a second time with the sealed cavity inside the outlet connection part 12 when it flows out from the multiple bubble generating holes 7 of the outlet hurricane plate 6. This effectively microbubbles the bubbly air or dissolved air in the tap water. This allows users to easily generate microbubble water by simply replacing the connector, and the replaced water gun can be used in the same way as the original water gun without the need for readjustment.

[0050] Example 2

[0051] Based on Embodiment 1, the central axis of the bubble generating hole 7 on the inlet hurricane plate 5 or the outlet hurricane plate 6 is set to be inclined to the central axis of the inner core 1; the bubble generating hole 7 is set as a tapered hole with a gradually decreasing diameter along the water flow direction.

[0052] Example 3

[0053] Referring to Figure 5, based on Embodiment 1, the adapter 4 includes a sleeve 41 and a base 42. The sleeve 41 is coaxially sleeved with the guide connector 13, and the base 42 is disposed at the bottom of the guide connector 13. The outer surface of the sleeve 41 is provided with a plurality of flanges 43.

[0054] In this embodiment, by sleeved with the guide connector 13 inside the water inlet connection 11, the conversion connector 4 includes a sleeve 41, which facilitates the installation and replacement of conversion connectors 4 of different thicknesses by sleeve. This allows the water gun connector of this utility model to adapt to different water gun water supply hose connections, increasing the versatility of the water gun connector, and it has the characteristics of simple operation and high flexibility.

[0055] Furthermore, by providing several flanges 43 on the outer surface of the sleeve 41, not only can the structural strength of the guide joint 13 be enhanced, but the contact area between the water supply hose and the sleeve 41 can also be deformed by the flanges 43, thereby enhancing the sealing effect at the connection.

[0056] Example 4

[0057] Referring to Figures 1-9, based on Embodiment 1 or 3 above, the inner wall of the outer shell 3 is provided with a guide slider 31; the outer wall of the water outlet connection part 12 is provided with a guide groove 121 corresponding to the guide slider 31, and the outer shell 3 slides along the guide groove 121 via the guide slider 31; the bottom of the guide groove 121 is provided with a mounting hole 1211 and a support bar 1212, and a buckle 122 is provided in the guide groove 121, the buckle 122 being used to engage the end of the water gun connected to the water outlet connection part 12; the buckle 122 includes a spring piece 1221 and a boss 1222 provided on the spring piece 1221, the spring piece 1221 is accommodated in the bottom of the guide groove 121, and one end of the spring piece 1221 abuts against the support bar 1212, and the boss 1222 is accommodated in the mounting hole 1211.

[0058] When the guide slider 31 slides along the guide groove 121, the guide slider 31 interferes with the buckle 122, and the boss 1222 extends through the mounting hole 1211 to the inner wall of the water outlet connection 12. A plurality of buckles 122 form the buckle structure.

[0059] The top end of the water inlet connection 11 is provided with a plurality of clamping members 16, and the inner side of the clamping member 16 is provided with a clamping groove. The clamping member 16 is used to close towards the center to clamp the water inlet pipe when the threaded joint 2 is threadedly connected to the water inlet connection 11.

[0060] In this embodiment, during the installation process by rotating the threaded connector 2 along the thread direction, the interior of the threaded connector 2 abuts against several clamping members 16 provided at the top of the water inlet connection 11, causing the clamping members 16 to close towards the center of the water inlet connection 11, thereby clamping and fixing the water supply hose located between the water inlet connection 11 and the guide connector 13, which facilitates the installation and adjustment of the water supply hose; and, through the buckling structure formed by multiple buckles 122, under the sliding interference of the guide slider 31, the buckling structure can lock or release the water gun.

[0061] In one application scenario of this embodiment, the spring piece 1221 is configured as an arc-shaped structure with a certain angle. In the clamping state, when the guide slider 31 slides upward along the guide groove 121 toward the water inlet connection 11, the guide slider 31 abuts against the spring piece 1221, so that the guide slider 31, the spring piece 122 and the support bar 1212 abut together, releasing the abutment and fixation of the guide slider 31 against the boss 1222. At the same time, since the spring piece 1221 has a certain curvature, the boss 1222 at one end of the spring piece 1221 is pulled outward from the mounting hole 1211, releasing the locking state of the buckle structure. Conversely, when the guide slider 31 slides downward along the guide groove 121 toward the water outlet connection 12, the boss 1222 extends out from the inner wall surface of the water outlet connection 12, thereby clamping the water gun connection part in the water outlet connection 12.

[0062] Example 5

[0063] Based on embodiment 4, the inner wall of the water outlet connection 12 is provided with a stepped structure 123. The stepped structure 123 is used to form a sealed cavity when connected with the water gun. The sealed cavity is the cavity between the top of the stepped structure 123 and the water outlet hurricane plate 6. An elastic member 8 is provided between the outer shell 3 and the water outlet connection 12. One end of the elastic member 8 abuts against the connection between the water outlet connection 12 and the water inlet connection 11, and the other end of the elastic member 8 abuts against the top of the guide slider 31. This is used to reset the outer shell 3 after sliding by the elastic deformation of the elastic member 8, keeping the buckle structure formed by the buckle 122 in a locked state. The elastic member 8 can be a spring.

[0064] Example 6

[0065] Referring to Figures 7 and 8, based on Embodiment 5, the outer side of the water outlet connection 12 includes a first outer wall surface 1201 and a second outer wall surface 1202. The first outer wall surface 1201 is disposed on the side near the water inlet connection 11, and the second outer wall surface 1202 is disposed on the side near the end of the water outlet connection 12. The outer diameter of the second outer wall surface 1202 is larger than the outer diameter of the first outer wall surface 1201. The elastic member 8 is sleeved on the outer side of the first outer wall surface 1201.

[0066] The guide groove 121 includes two side plates 1213 arranged opposite to each other. One end of the side plate 1213 facing the water inlet connection 11 is provided with a clearance notch, which is used to avoid the elastic element when the outer shell 3 moves up and down.

[0067] The inner core 1 has an annular limiting part 15 at one end of the water outlet connection part 12.

[0068] An anti-detachment fastener 33 is provided on the inner side of the outer shell 3. The anti-detachment fastener 33 has a fan-shaped structure and engages with the lower limit part 15 when the outer shell 3 is sleeved with the inner core 1.

[0069] The anti-detachment fastener 33 includes a base 331 and an outwardly curved fin 332; the base 331 protrudes from the bottom inner side of the outer casing 3, and the fin 332 extends toward the end of the outer casing 3.

[0070] The anti-detachment fastener 33 is provided in a plurality of units, which are arranged along the circumferential direction.

[0071] In this embodiment, the two side plates 1213 of the guide groove 121, which are arranged opposite each other, can not only move the guide slider 31 in a predetermined direction, but also serve as structural reinforcement of the water outlet connection 12, so as to avoid the water outlet connection 12 being provided with multiple parts.

[0072] Example 7

[0073] Referring to Figures 7 and 8, based on any one of Embodiments 1-6, a partition baffle 17 is provided between the water inlet connection 11 and the water outlet connection 12. The partition baffle 17 has an upper end face, a lower end face, and a reinforcing rib disposed between the upper end face and the lower end face. The upper end face is used to position and install the threaded connector 2, and the lower end face is used to position and install the outer shell 3.

[0074] In this embodiment, the upper end face of the partition baffle 17 is used to prevent the threaded connector 2 from being over-installed during installation, and can also visually demonstrate whether the threaded connector 2 is installed in place (the threaded connector 2 and the upper end face are just abutting). The diameter of the lower end face of the partition baffle 17 is smaller than the inner diameter of the outer shell 3. The lower end face of the partition baffle 17 can be used to abut against the elastic element, so that the end of the elastic element that abuts against the lower end face forms a fixed end, and the end of the elastic element that abuts against the outer shell 3 is a movable end. In the normal relaxed state, the elastic element makes the top of the outer shell 3 just flush with the lower end face. At the same time, it can also visually demonstrate whether the current buckle structure is in a locked state (if the top of the outer shell 3 is just flush with the lower end face, it is locked; otherwise, it may not be locked in place).

[0075] The outer surface of the outer casing 3 is provided with anti-slip texture 32; the outer surface of the outer casing 3 is provided with directional markings, which are arranged adjacent to the anti-slip texture 32.

[0076] In this embodiment, the outer surface of the outer shell 3 is also provided with anti-slip texture 32 and direction markings, which makes it easy to use.

[0077] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
