[0026] like Figures 1 to 4 As shown, Figure 1 The figure shows a front view of a bubble water spraying device provided by the present invention. Figure 2 Shown is an exploded view of a bubble water spraying device provided by the present invention. Figure 3 A schematic diagram showing the initial state of a bubble water spraying device provided by the present invention is shown. Figure 4 A schematic diagram showing the water discharge state of a bubble water spraying device provided by the present invention is shown.

[0027] The bubble water spraying device of an embodiment of the present invention includes a spraying housing 1 and a reciprocating assembly 2. The spraying housing 1 encloses a spraying chamber 11 and is provided with a water inlet 12 and a water outlet 13. The reciprocating assembly 2 is connected to and disposed within the spraying chamber 11. The water inlet 12 communicates with the spraying chamber 11. High-pressure water entering the spraying chamber 11 propels the reciprocating assembly 2 to move, thereby connecting the water outlet 13 with the spraying chamber 11. The water outlet 13 includes a tapered section 131 and a diverging section 132, which are sequentially connected. The tapered section 131 is located near the spraying chamber 11, so that the negative pressure generated by the diverging section 132 allows dissolved gases in the high-pressure water to escape, forming high-pressure bubble water with micro-nano bubbles.

[0028] like Figures 1 to 4As shown, the spray housing 1 is surrounded to form a spray chamber 11. Preferably, the spray housing 1 includes a spray barrel 15, a first end wall 16 and a second end wall 17, wherein the spray barrel 15 is a tubular structure, the first end wall 16 closes the left end of the spray barrel 15, and the second end wall 17 closes the right end of the spray barrel 15. Preferably, the second end wall 17 is sealed and fixed to the right end of the spray barrel 15 through a sealing gasket 4. The left end of the reciprocating assembly 2 is connected to the first end wall 16, and the right end of the reciprocating assembly 2 is connected to the second end wall 17, which can facilitate the connection of the reciprocating assembly 2 to the spray housing 1. The reciprocating assembly 2 is in the spray chamber 1. 1 can reciprocate. In the initial state, the reciprocating component 2 is located on the right side of the spray chamber 11, so that the water inlet 12 is connected to the spray chamber 11. When the water inlet 12 is connected to the water pump 3 or the indoor pipeline, water enters the spray chamber 11 through the water inlet 12. After the spray chamber 11 is filled, further water inflow can increase the water pressure in the spray chamber 11 to generate high-pressure water. The continuous high water pressure pushes the reciprocating component 2 to move to the left, thereby connecting the water outlet 13 and the spray chamber 11. The high-pressure water is sprayed out from the water outlet 13, reducing the water pressure in the spray chamber 11, so that the reciprocating component 2 moves rightward to the initial state, and the cycle repeats.

[0029] The water outlet 13 includes a tapered section 131 and a gradually expanding section 132 arranged in sequence from the inside to the outside, which is similar to a Venturi structure. The water initially entering the spray chamber 11 usually has some gaseous substances in the air dissolved in the water. The high-pressure water sharply reduces the cross-section of the tapered section 131 to produce high-speed flow. The high-speed flowing water forms a negative pressure in the gradually expanding section 132. The gas dissolved in the water escapes due to supersaturation and forms micro-nano bubbles in the water. As the water flows outward along the gradually expanding section 132, the pressure continues to decrease, and the micro-nano bubbles continue to expand. When the micro-nano bubble water is sprayed onto the surface of the object to be cleaned, such as the range hood, the external environment pressure is restored, and the micro-nano bubbles burst instantly. The strong impact generated by the rupture has a collision and peeling effect on the dirt on the surface of the object to be cleaned. Combined with the impact of the high-speed water flow, a cleaner decontamination effect is achieved.

[0030] Preferably, the bubble water spraying device also includes a water pump 3, which is connected to the water inlet 12 to increase the pressure of the water pump 3 entering the spraying chamber 11. When the water pump 3 is a pulse water pump 3, the pulse water pump 3 is converted to a low-pressure state when the reciprocating component 2 moves to the right, which can speed up the recovery of the bubble water spraying device to its initial state.

[0031] In a preferred embodiment of the present invention, the ratio of the length of the tapered section 131 to the length of the divergent section 132 is 1:2 to 1:7.

[0032] Among them, when the length of the tapering section 131 and the length of the gradually expanding section 132 are greater than 1:2, the cross-sectional change of the tapering section 131 is small, and it is difficult to generate sufficient negative pressure in the gradually expanding section 132 to allow the gas dissolved in the water to escape and form micro-nano bubbles. When the length of the tapering section 131 and the length of the gradually expanding section 132 are less than 1:7, the micro-nano bubbles burst before reaching the surface of the object to be cleaned, and their optimal decontamination effect cannot be achieved.

[0033] In a preferred embodiment of the present invention, the reciprocating assembly 2 includes a conductor 21, a valve core 22, a first spring 23 and a second spring 24. The spray housing 1 includes a spray barrel 15, a first end wall 16 and a second end wall 17. The spray barrel 15 is a cylindrical structure with openings at both ends. The first end wall 16 and the second end wall 17 are respectively connected to the openings at both ends of the spray barrel 15 to enclose and form a spray chamber 11. The conductor 21 is elastically connected to the second end wall 17 through the second spring 24 and is lockably sealed to the side wall of the spray barrel 15. The valve core 22 is elastically connected to the first end wall 16 through the first spring 23 and is sealed to the side wall of the spray barrel 15.

[0034] like Figures 2 to 4 As shown, the valve core 22 is elastically connected to the left end of the spray housing 1 through the first spring 23, and the conductor 21 is elastically connected to the right end of the spray housing 1 through the second spring 24. The right end of the valve core 22 and the left end of the conductor 21 are releasably offset. After water enters the spray chamber 11, it can only fill the right part of the spray chamber 11. In the initial state, the first spring 23 and the second spring 24 are respectively in a compressed state. At this time, the conductor 21 is at the right dead point and is locked. When a large amount of water enters the spray chamber 11 through the water inlet hole 12, pressure is generated, pushing When the valve core 22 moves to the left, the conductor 21 is unlocked and the lock of the conductor 21 is released. The conductor 21 moves to the right due to the action of the second spring 24, so that the part of the spray chamber 11 located on the right side of the conductor 21 is connected with the water outlet 13, so that high-pressure water is sprayed out through the water outlet 13. At this time, the water pressure in the spray chamber 11 is reduced, and the action of the first spring 23 causes the valve core 22 to move to the right, and the valve core 22 abuts against the conductor 21, thereby pushing the conductor 21 to move to the right and return to its initial state, and this cycle repeats.

[0035] Preferably, the outer circumferential surface of the valve core 22 is provided with a first sealing groove 223, in which a first sealing ring 5 is disposed. The valve core 22 is sealedly connected to the spray barrel 15 of the spray housing 1 via the first sealing ring 5, thereby ensuring the sealing of the right portion of the spray chamber 11. The outer circumferential surface of the conductor 21 is provided with a second sealing groove 214, in which a second sealing ring 6 is disposed. The conductor 21 is sealedly connected to the spray barrel 15 of the spray housing 1 via the second sealing ring 6, allowing water to completely enter the right-side spray chamber 11 of the conductor 21 through the water hole 221.

[0036] In a preferred embodiment of the present invention, the conductor 21 is a tubular structure. The inner wall of the conductor 21 is provided with a first step 211 , and the valve core 22 abuts against the first step 211 .

[0037] like Figure 3 and Figure 4 As shown, the conductor 21 is a tubular structure. When the conductor 21 is at its left dead point, water enters through the water inlet 12 and passes through the conductor 21 to reach the water outlet 13. The first step 211 is set on the inner wall of the conductor 21. When the valve core 22 abuts against the conductor 21, it directly abuts the left end surface of the first step 211, and the left end of the second spring 24 can also directly abut the right end surface of the first step 211.

[0038] In a preferred embodiment of the present invention, a water hole 221 is defined at one end of the valve core 22 close to the conductor 21 , so that when the valve core 22 abuts against the conductor 21 , high-pressure water flows through the water hole 221 and the conductor 21 to the water outlet 13 .

[0039] like Figures 2 to 4 As shown, the right end of the valve core 22 is passed through the conductor 21. When the right end periphery of the valve core 22 abuts against the first step 211, the water hole 221 is opened at the right end of the valve core 22 to connect the cavities on the left and right sides of the second step 251, so that water can flow to the water outlet 13 after entering the water inlet 12.

[0040] In a preferred embodiment of the present invention, the reciprocating assembly 2 further includes a stopper 25 and a third spring 26. The spray housing 1 is provided with a mounting groove 14. One end of the stopper 25 is connected to the conductor 21, and the other end is elastically connected to the mounting groove 14 through the third spring 26 to limit the movement stroke of the conductor 21.

[0041] like Figures 2 to 4 As shown, the third spring 26 is disposed in the mounting groove 14, the upper end of the third spring 26 is fixed to the spray housing 1, and the lower end of the third spring 26 is fixed to the stopper 25. The upper portion of the stopper 25 is in the mounting groove 14, so that the stopper 25 can slide along the mounting groove 14 under the action of the third spring 26 and the valve core 22. When the valve core 22 moves to the left, the stopper 25 is pressed to move into the mounting groove 14, thereby releasing the blockage of the guide 21 by the stopper 25. When the valve core 22 pushes the guide 21 to the right to return to its initial state, the stopper 25 extends from the mounting groove 14 due to the elastic force of the third spring 26, thereby locking the guide 21.

[0042] In a preferred embodiment of the present invention, a second step 251 is provided on the top periphery of the blocker 25, and a third step 212 is provided on the periphery of one end of the conductor 21 close to the valve core 22. The third step 212 cooperates with the second step 251 to form an interlocking state of the blocker 25 and the conductor 21.

[0043] like Figures 2 to 4 As shown, a second step 251 is provided on the top periphery of the blocker 25, so that the blocker 25 is divided into an upper blocking large end and a lower blocking small end, and a third step 212 is provided on the left side of the conductor 21, so that the conductor 21 is divided into a left conductive small end and a right conductive large end. In the initial state, the step surface of the third step 212 fits the surface of the blocking large end of the blocker 25, and the blocking small end of the blocker 25 extends into the conductor 21. The step surface of the second step 251 fits the conductive small end of the conductor 21, then an interlocking state of the blocker 25 and the conductor 21 can be formed.

[0044] In a preferred embodiment of the present invention, a first inclined surface 222 is provided at one end of the valve core 22 close to the conductor 21. The first inclined surface 222 is used to squeeze the blocker 25 to move toward the installation groove 14 to release the interlocking state between the blocker 25 and the conductor 21.

[0045] like Figures 2 to 4 As shown, the first inclined surface 222 extends outward from left to right along the radial direction of the valve core 22, so that the right end of the valve core 22 is a bell-mouth structure. When the valve core 22 moves to the left, the top of the blocker 25 can be retracted a certain distance into the installation groove 14 along the first inclined surface 222.

[0046] In a preferred embodiment of the present invention, a receiving groove 213 extending along the axial direction of the conductor 21 is provided at the conductor 21 corresponding to the blocker 25, so that when the blocker 25 and the conductor 21 are released from the interlocking state, the top of the blocker 25 is set in the receiving groove 213.

[0047] like Figure 3 and Figure 4 As shown, when the valve core 22 moves to the left and pushes the blocker 25 to move upward, since the outer periphery of the valve core 22 fits against the inner wall of the conductor 21, the maximum upward movement of the blocker 25 can only make the bottom surface of the blocker 25 flush with the inner wall of the conductor 21. In order to prevent the blocking small end of the blocker 25 from interfering with the conductor 21, a receiving groove 213 is opened along the axial direction of the left end of the conductor 21. The width of the receiving groove 213 is slightly larger than the diameter of the blocking small end. When the conductor 21 moves to the left, the blocking small end of the blocker 25 can slide in the receiving groove 213 until the blocking large end of the blocker 25 abuts against the third step 212.

[0048] In a preferred embodiment of the present invention, the bubble water spraying device further includes a water pump 3 , and a water outlet of the water pump 3 is connected to the water inlet 12 .

[0049] like Figure 3 and Figure 4 As shown, the water pump 3 is arranged at the water inlet 12 to increase the water pressure of the water pump 3 entering the spray chamber 11, especially when the water pump 3 is a pulse water pump 3, it can speed up the speed of the reciprocating component 2 returning to its initial state.

[0050] The bubble water spraying device of the present invention allows high-pressure water to flow through the tapered section 131 and the gradually expanding section 132 in sequence, thereby generating negative pressure in the gradually expanding section 132 to squeeze the gas dissolved in the high-pressure water to form micro-bubble water, which has an impact and peeling effect on the dirt on the surface of the object to be cleaned. Combined with the impact of the high-speed water flow, a cleaner cleaning effect is achieved; the conductor 21 is locked by the blocker 25, and the second spring 24 stores a certain amount of elastic potential energy in the initial state, so that the valve core 22 drives the blocker 25 to retract. When the conductor 21 is unlocked, the conductor 21 can move toward the side where the valve core 22 is located, thereby connecting the water outlet 13 and the spray chamber 11; the water pump 3 is arranged at the water inlet hole 12 to increase the water pressure of the water pump 3 entering the spray chamber 11, especially when the water pump 3 is a pulse water pump 3, it can accelerate the speed of the reciprocating component 2 returning to its initial state.
