[0057] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0058] Reference Figure 1 and Figure 2The embodiment of the present application provides a water spraying toy 100, which comprises a toy body 200 and a water valve 300, and the water valve 300 is used for controlling the water spraying of the toy body 200 to meet the water playing demand of children.

[0059] Specifically, as shown in Figure 1 and Figure 2 , the toy body 200 comprises an air-filled chamber 210, and the water valve 300 is connected to the wall of the air-filled chamber 210 through a rubber coating structure 401 (as shown in the figure) to be arranged in the air-filled chamber 210. Figure 3

[0060] In the embodiment, the air-filled chamber 210 comprises a main air-filled chamber 201 and a plurality of auxiliary air-filled chambers 202, and the main air-filled chamber 201 and the plurality of auxiliary air-filled chambers 202 can be in communication with each other or not. Each of the auxiliary air-filled chambers 202 is provided with a water spraying chamber 203, and the wall of the water spraying chamber 203 is provided with a water spraying hole 204 in communication with the outside.

[0061] The water valve 300 described above is located in the main air-filled chamber 201, and the water valve 300 comprises a water inlet channel 301, a shower water spraying port 302 and a plurality of water outlet channels 303, wherein the water inlet channel 301 is used for connecting a water source. Exemplarily, one water inlet channel 301 is provided in the embodiment, which is connected with a first external water pipe 205, the first external water pipe 205 passes through any one of the auxiliary air-filled chambers 202 from the main air-filled chamber 201 and is finally extended to the outside to connect an external water source. However, it can be understood by those skilled in the art that in other embodiments, other numbers of water inlet channels 301 can be provided, which are respectively connected with the first external water pipe 205 to realize water supply at multiple points through the plurality of first external water pipes 205. Further, the first external water pipe 205 can also directly pass out from the main air-filled chamber 201 to connect the external water source without passing through the auxiliary air-filled chamber 202.

[0062] In addition, it can be understood that in other embodiments, the water valve 300 can also be arranged in the auxiliary air-filled chamber 202.

[0063] As shown in Figure 1 and Figure 2 , the shower water spraying port 302 of the water valve 300 is exposed to the main air-filled chamber 201 and is in continuous communication with the water inlet channel 301. It can be understood that the shower water spraying port 302 is dispersedly sprayed to the surrounding. Since the shower water spraying port 302 is in a state of continuous communication with the water inlet channel 301, as long as the water flow enters the water inlet channel 301, the shower water spraying port 302 will continuously disperse water to the surrounding for the children to play.

[0066] The water inlet channel 301 of the water valve 300 of the embodiment is in turn communicated with the plurality of water outlet channels 303, that is, at the same time, the water inlet channel 301 is only communicated with one water outlet channel 303 of the plurality of water outlet channels 303, that is, at this moment, only the water outlet channel 303 is supplied with water, so that the water spraying hole 204 on the water spraying chamber 203 in the sub-air chamber 202 corresponding to the water outlet channel 303 sprays water linearly outward, and the other water outlet channels 303 are not supplied with water.

[0067] Briefly, the water valve 300 of the embodiment can realize the purpose of sequentially and alternately circulating water supply to the plurality of water outlet channels 303, and the plurality of water spraying chambers 203 of the toy body 200 can automatically and cyclically switch water outlet, so as to realize the effect of automatic intermittent water spraying. In this way, the water spraying toy 100 is changed from the original static water spraying to dynamic water spraying, and the fun is improved. In addition, the plurality of water spraying chambers 203 corresponding to the plurality of water outlet channels 303 which alternately spray water are matched with the shower nozzle 302 which continuously and dispersively sprays water, so as to give children a better water playing experience.

[0068] It should be noted that in the embodiment, the water valve 300 is provided with one water inlet channel 301 and three water outlet channels 303, and the three water outlet channels 303 match the three sub-air chambers 202. However, those skilled in the art can understand that in other embodiments, other numbers of water outlet channels 303 and sub-air chambers 202 corresponding thereto can also be provided, such as four, five, etc. In addition, a plurality of water spraying chambers 203 can also be provided in one sub-air chamber 202, so as to correspond to a plurality of water outlet channels 303, so as to realize the purpose of alternately spraying water from a plurality of points of one sub-air chamber 202.

The initial state of the rotating member 900 is in fluid communication with one of the water outlet channels 303, and the rotating member 900 can correspond to one water outlet channel 303 every 120° of rotation, so as to realize the sequential and circulating water supply to the three water outlet channels 303, and also make the water spray cavity 203 in the toy body 200 in communication with the three water outlet channels 303 to sequentially and circularly spray water, thereby meeting the entertainment needs of children.

[0086] Reference Figure 4 , Figure 8 to Figure 10, the water flow entering from the water inlet channel 301 flows into the first chamber 540, and the water flow in the first chamber 540 flows into the water storage cavity 110 through the water distribution pipe 801 of the connecting piece 800. At the same time, the water flow entering the first chamber 540 drives the impeller 600 to rotate in the first chamber 540, the rotation of the impeller 600 drives the transmission assembly 700 to rotate, the transmission assembly 700 transmits power to the rotating piece 900, so that the rotating piece 900 rotates in the second chamber 560, and the water outlet hole 901 of the rotating piece 900 also rotates synchronously with the rotation of the rotating piece 900. When the rotating piece 900 rotates by a preset angle, the water outlet hole 901 is in fluid communication with one of the plurality of water outlet channels 303, that is, the water outlet hole 901 fluidly connects the water storage cavity 110 and the water outlet channel 303, so that the water in the water storage cavity 110 flows to the water outlet channel 303 through the water outlet hole 901, and finally flows to the water spray chamber 203 in the corresponding toy body 200 to be sprayed from the water spray hole 204 of the water spray chamber 203. When the rotating piece 900 continues to rotate under the drive of the impeller 600, the water outlet hole 901 leaves the last water outlet channel 303 and fluidly connects with other water outlet channels 303 adjacent to the last water outlet channel 303, so as to supply water to the other water outlet channels 303 from the water storage cavity 110, that is, to make the water spray chamber 203 in the other auxiliary inflation chamber 202 of the toy body 200 spray water. In this way, the rotating piece 900 rotates 360°, and the plurality of water outlet channels 303 arranged at intervals along the circumferential direction R are sequentially and alternately realized to spray water once, so as to realize the effect of automatic intermittent water spraying of the water spray chamber 203 of the plurality of auxiliary inflation chambers 202. In this way, the water spray toy 100 changes from the original static water spraying to dynamic water spraying, improving the water play fun.

[0087] In the embodiment, as shown in Figure 8 and Figure 10 , the rotating piece 900 includes a water storage portion 910 and a connecting portion 920 protruding on the upper surface of the water storage portion 910. The water storage portion 910 is hollow inside and the lower end of the water storage portion 910 is open to define the water storage cavity 110 with the bottom wall of the second chamber 560. The water outlet hole 901 is arranged on the outer wall of the water storage portion 910.

[0088] It can be understood that in another embodiment, the water storage portion 910 is hollow inside and the lower end of the water storage portion 910 is closed to form the water storage cavity 110.

[0089] Exemplarily, the water storage portion 910 and the connecting portion 920 of the rotating piece 900 are both in cylindrical shape and coaxial, and the outer diameter of the connecting portion 920 is smaller than the outer diameter of the water storage portion 910.

[0090] Referring to Figure 4 , Figure 8 andFigure 11 The connecting piece 800 comprises a fixed part 802 in communication with the water distribution pipe 801, the upper surface of the water storage part 910 abuts against the fixed part 802, that is, the fixed part 802 is arranged on the upper surface of the water storage part 910, and the connecting part 920 is arranged in the fixed part 802, and the transmission assembly 700 is connected with the connecting part 920.

[0091] Exemplarily, the fixed part 802 also has a cylindrical shape, and both upper and lower ends thereof are open, the upper surface of the water storage part 910 abuts against the fixed part 802, and the connecting part 920 protruding from the upper surface of the water storage part 910 extends into the fixed part 802, and the annular space formed by the inner wall of the fixed part 802 and the outer wall of the connecting part 920 accommodates the water from the water distribution pipe 801 of the connecting piece 800. The connecting part 920 is provided with a connecting hole 921, and one end of the transmission assembly 700 extends into the connecting hole 921 to realize the connection between the transmission assembly 700 and the rotating piece 900, so that the rotating piece 900 can be driven to rotate by the transmission assembly 700 when the impeller 600 rotates.

[0092] As shown in Figure 10 and Figure 11 , the upper surface of the water storage part 910 is provided with a plurality of water passing holes 911 at intervals, and the plurality of water passing holes 911 are in fluid communication with the water storage cavity 110 and the annular space formed by the inner wall of the fixed part 802 and the outer wall of the connecting part 920. Exemplarily, the plurality of water passing holes 911 are arranged in the annular region between the outer edge of the upper surface of the water storage part 910 and the connecting part 920, and the water flowing in the water distribution pipe 801 of the connecting piece 800 flows into the fixed part 802 and then flows into the water storage cavity 110 through the water passing holes 911.

[0093] In the embodiment, the upper surface of the water storage part 910 is provided with 12 water passing holes 911 at equal intervals, so that the water flow can uniformly flow into the water storage cavity 110 through the water passing holes 911 arranged at intervals. It can be understood by those skilled in the art that, in other embodiments, the upper surface of the water storage part 910 can also be provided with other numbers of water passing holes 911 at intervals, for example, 8, 9, 10, 11, 13, etc., and further, the plurality of water passing holes 911 can also be arranged at unequal intervals.

[0094] As shown in Figure 9 , the fourth inner recessed region 531 of the third shell 530 is provided with a mounting seat 570, and the mounting seat 570 and the bottom wall of the second cavity 560 (that is, the bottom wall of the fourth inner recessed region 531) define a mounting cavity 572. Exemplarily, the mounting seat 570 has a cylindrical shape, is located at the center of the third shell 530, and is integrally formed with the third shell 530.

[0095] Referring to Figure 8 to Figure 11The rotating member 900 and the fixed part 802 of the connecting member 800 are located in the mounting cavity 572, and the outer wall of the water storage part 910 is attached to the wall of the mounting cavity 572, that is, the water storage part 910 of the rotating member 900 is coaxial with the mounting cavity 572, and the water outlet hole 901 on the outer wall of the water storage part 910 is opposite the wall of the mounting cavity 572.

[0096] The plurality of water outlet channels 303 are arranged at intervals in the circumferential direction (i.e., the circumferential direction R) of the wall of the mounting cavity 572, and any one of the plurality of water outlet channels 303 is in fluid communication with the mounting cavity 572. For example, one end of each water outlet channel 303 penetrates the wall of the mounting cavity 572 to be in fluid communication with the mounting cavity 572, and the other end of each water outlet channel 303 extends out of the fourth recessed area 531, that is, out of the third shell 530.

[0097] Continuing to refer to Figure 8 to Figure 11 The impeller 600 drives the rotating member 900 to rotate in the second cavity 560, and the water outlet hole 901 on the outer wall of the water storage part 910 rotates relative to the wall of the mounting cavity 572. The water outlet hole 901 is rotated to a set angle, which corresponds to the position of one of the plurality of water outlet channels 303 that penetrates the wall of the mounting cavity 572. At this time, the water storage cavity 110 and the water outlet channel 303 are in fluid communication through the water outlet hole 901, and the water in the water storage cavity 110 flows into the water outlet channel 303 through the water outlet hole 901 and eventually flows out of the water outlet channel 303. The continuous rotation of the rotating member 900 in the second cavity 560 causes the water storage cavity 110 to be sequentially and cyclically connected to the plurality of water outlet channels 303 through the water outlet hole 901. The water outlet hole 901 is rotated to the corresponding water outlet channel 303, which is in water outlet, while the other water outlet channels 303 are not in water outlet, thereby realizing the automatic and cyclic switching of the plurality of water outlet channels 303 and achieving the effect of automatic and intermittent water spraying of the toy body 200.

[0098] It can be understood that the rotation speed of the impeller 600 determines the water outlet time of the water outlet channel 303 to some extent. That is, if the rotation speed of the impeller 600 is slow, that is, the rotation speed of the rotating member 900 is slow, the duration of the water outlet hole 901 and the water outlet channel 303 connected thereto remaining in communication is long, and the water outlet time of the water outlet channel 303 is long. On the contrary, if the rotation speed of the impeller 600 is fast, the duration of the water outlet hole 901 and the water outlet channel 303 connected thereto remaining in communication is short, and the water outlet time of the water outlet channel 303 is short, that is, the next water outlet channel 303 is switched to water outlet in a relatively fast time.

[0099] It should be noted that since the water outlet passage 303 is in fluid communication with the water storage cavity 110 through the mounting cavity 572, and the water storage cavity 110 and the mounting cavity 572 are in a surrounding relationship, that is, the impeller 600 rotates 360°, and must pass through three water outlet passages 303, and as long as it passes through one water outlet passage 303, the water outlet hole 901 will be in communication with the water outlet passage 303, that is, the water outlet hole 901 and the plurality of water outlet passages 303 are sequentially and alternately communicated.

[0100] Exemplarily, the outer wall of the fixed part 802 is provided with a third sealing ring 805, and the outer wall of the fixed part 802 and the inner wall of the mounting cavity 572 jointly extrude the third sealing ring 805, thereby forming a seal between the fixed part 802 and the mounting cavity 572, so as to avoid water in the water storage cavity 110 from leaking upward.

[0101] As shown in Figure 9 and Figure 12 , the top of the mounting seat 570 is provided with a limiting groove 571, and the outer wall of the fixed part 802 of the connecting piece 800 is provided with a protrusion 803 matched with the limiting groove 571, so as to limit the rotation of the connecting piece 800 relative to the mounting seat 570. In the embodiment, the top of the mounting seat 570 is provided with two limiting grooves 571, and correspondingly, the outer wall of the fixed part 802 is provided with two protrusions 803, and the protrusions 803 can be embedded in the corresponding limiting grooves 571, so as to facilitate the assembly of the connecting piece 800, and also limit the rotation of the connecting piece 800 relative to the mounting seat 570.

[0102] Exemplarily, as shown in Figure 9 , Figure 11 and Figure 12 , the water distribution pipe 801 is in L shape. The outer wall of the mounting seat 570 is outwardly provided with a supporting part 532, and the supporting part 532 includes a containing groove 533 for supporting the water distribution pipe 801 of the connecting piece 800.

The impeller shaft 602 of the impeller 600 is provided with an eighth gear portion 605, and the eighth gear portion 605 is engaged with the seventh gear portion 742. The gears of the gear set connect the impeller 600 and the rotating member 900 to achieve the effect of power transmission. Those skilled in the art can understand that, in other embodiments, other transmission assemblies such as shaft couplings can also be used for transmission connection.

The first mounting hole 528 is used for the impeller shaft 602 to extend into the first mounting space 527 and engage with the seventh gear portion 742 of the fourth gear 740. As shown in Figure 8 , Figure 10 and Figure 13As shown, the lower end of the second installation space 562 is provided with a second installation hole 563, so that the first shaft 711 of the first gear 710 extends out of the first installation space 527 and is connected with the rotating member 900.

The center of the upper end of the first shaft 711 of the first gear 710 is provided with a center groove 713, and the center groove 713 is provided for inserting a rotating shaft 714. One end of the rotating shaft 714 is sleeved with a first shaft sleeve 715, and the first shaft sleeve 715 is embedded in the first cylindrical groove 581. The first gear 710 and the rotating shaft 714 can rotate relative to the first shaft sleeve 715. In this way, the positioning of the first gear 710 in the gear installation space 580 is realized, and it is ensured that the first gear 710 can rotate in the gear installation space 580 under the action of the impeller 600.

[0108] As shown in Figure 7 , Figure 10 , Figure 12 and Figure 13 , the second gear 720 includes a second shaft (not shown in the figure), the upper end of the second shaft is sleeved with a second shaft sleeve 723, the second shaft sleeve 723 is embedded in the second cylindrical groove 582, and the lower end of the second shaft is sleeved with a third shaft sleeve (not shown in the figure), the third shaft sleeve is embedded in the fifth cylindrical groove 564.
