[0005] In order to achieve the above-mentioned utility model purpose, the utility model is implemented through the following technical solutions:

[0006] A water spraying brush comprises a brush handle, a brush head and a water spraying device, wherein the water spraying device comprises a liquid storage chamber arranged on the brush handle, the liquid storage chamber is sealed and provided with a water inlet plug, a water outlet plug and a switch, the liquid storage chamber is provided with a water inlet and a water outlet, the water outlet is provided with a water outlet plug, the switch is pressed to open the water outlet plug through air pressure, and the water outlet discharges water to the bottom of the brush head, the water inlet is detachably installed with a water inlet plug, and the water inlet plug is provided with an exhaust groove, and when the water inlet plug is installed, the exhaust groove exhausts air outwardly, so that the liquid storage chamber maintains air pressure balance with the outside world. A water inlet plug and a water outlet plug are arranged on the liquid storage chamber to make the liquid storage chamber in a sealed state. The volume of the liquid storage chamber is reduced by pressing the switch to increase the pressure of the gas and liquid inside the liquid storage chamber, and drive the water outlet plug to open and spray water outward. The overall structure of the water spraying device is simple and the assembly is more convenient. In addition, a general water inlet plug will be inserted into the liquid storage chamber to reduce the volume of the liquid storage chamber when the cover is closed. After the water inlet plug is closed, the air is compressed to make the air pressure in the liquid storage chamber greater than the atmospheric pressure. In order to maintain the balance of internal and external air pressures, the water outlet plug is easy to open and spray water. The arrangement of the exhaust groove makes it convenient for part of the air in the liquid storage chamber to be compressed and flow out from the exhaust groove when the water inlet plug is installed, thereby achieving the balance of air pressure inside and outside the liquid storage chamber and preventing liquid from flowing out.

[0007] Preferably, a first sealing layer is provided at the end of the exhaust groove. When the water inlet plug is installed to a preset position, the first sealing layer blocks the water inlet so that the liquid storage cavity remains sealed. The exhaust groove extends along the movable direction of the water inlet plug, and can always exhaust air outward when the water inlet plug enters the liquid storage cavity. The first sealing layer is provided so that the liquid storage cavity is in a sealed state after the water inlet plug is installed in place.

[0008] Preferably, the water inlet plug is further provided with a second sealing layer, the first sealing layer and the second sealing layer both protrude outward along the side of the water inlet plug, and an annular groove is formed between the first sealing layer and the second sealing layer, the edge of the water inlet can be inserted into the annular groove, and the first sealing layer and the second sealing layer form a seal on the inner and outer sides of the water inlet respectively. By clamping the edge of the water inlet by the first sealing layer and the sealing layer, the sealing effect of the water inlet plug is better, and air and water leakage of the water inlet is avoided.

[0009] Preferably, the switch is made of a flexible material, a through hole is provided on the liquid storage cavity, and the switch is fixedly mounted on the through hole to block the through hole, and the switch is pressed to deform into the liquid storage cavity, the volume of the liquid storage cavity is reduced, and the gas and liquid inside leave from the water outlet plug.

[0010] Preferably, the switch includes a top surface and a side surface, the through hole is provided with a fixing frame extending outward, the side surface of the switch is sleeved on the outside of the fixing frame, and the side surface of the switch is sealed and connected to the fixing frame. The setting of the fixing frame facilitates the installation of the switch.

[0011] Preferably, a pressing groove is provided on the top of the fixing frame, a step is formed between the pressing groove and the fixing frame, and the inner surface and the end of the side of the switch are respectively fitted with the pressing groove and the step. The fixing frame and the switch are connected with multiple surfaces to expand the matching area so that the sealing connection effect of the two is better.

[0012] Preferably, the inner surface of the switch side and the pressing groove, and the end of the switch side and the step are sealed and fixed by glue. Glue can meet the requirements of sealing and fixing, and has low cost and convenient assembly.

[0013] Preferably, the top surface of the switch is arc-shaped, and the thickness of the top surface of the switch is smaller than the thickness of the side surface of the switch. The arc-shaped setting can increase the volume of the switch that is compressed by deformation, and the thickness difference between the top surface and the side surface of the switch can facilitate the top surface of the switch to deform under force, thereby preventing the side surface from following the deformation and causing tearing and air leakage between the switch and the fixing frame.

[0014] Preferably, the brush handle and the brush head are detachably connected, and the brush head is provided with a drainage hole at a position corresponding to the water outlet, and the drainage hole penetrates along the vertical direction of the brush head.

[0024] like Figure 1-5 A water spraying brush comprises a brush handle 1, a brush head 2 and a water spraying device, the water spraying device comprises a liquid storage chamber 3 arranged on the brush handle 1, the liquid storage chamber 3 is sealed, and is provided with a water inlet plug 4, a water outlet plug 5 and a switch 6, the liquid storage chamber 3 is provided with a water inlet 7 and a water outlet 8, the water outlet 8 is provided with a water outlet plug 5, the switch 6 is pressed to open the water outlet plug 5 through air pressure, and the water outlet 8 discharges water to the bottom of the brush head 2, the water inlet 7 is detachably installed with the water inlet plug 4, and the water inlet plug 4 is provided with an exhaust groove 9, and when the water inlet plug 4 is installed, the exhaust groove 9 exhausts air outwardly, so that the liquid storage chamber 3 maintains air pressure balance with the outside world.

[0025] In this embodiment, the water inlet 7 is arranged on a side away from the brush head 2, and the water outlet 8 is arranged on a side close to the brush head 2. Figure 1 As shown, the water inlet 7 is located at the upper side, and the water outlet 8 is located at the lower end. The liquid in the liquid storage chamber 3 is contained from bottom to top due to gravity, and after pressing the switch 6, the liquid flows out to the water outlet 8 below.

[0026] The water spray device in this embodiment discharges liquid through a sealed and pressed structure. Water is added through the water inlet 7, liquid is discharged through the water outlet 8 and the switch 6 is controlled. The water inlet plug 4 and the water outlet plug 5 seal the liquid storage chamber 3. When liquid is added to the liquid storage chamber 3, the liquid flows into the liquid storage chamber 3 from the water inlet 7. At the same time when the liquid enters the liquid storage chamber 3, the same volume of air in the liquid storage chamber 3 is discharged from the water inlet 7. When the liquid is added and the water inlet plug 4 is closed, the traditional press-type sealing plug or the threaded sealing plug, because it extends into the liquid storage chamber 3 or the air in the inner cavity of the sealing plug enters the liquid storage chamber 3, as the sealing plug is closed, the storage chamber 3 is closed. The reduction in the volume of the liquid cavity 3 or the excess air compression increases the air pressure and hydraulic pressure in the liquid storage cavity 3, and is greater than the atmospheric pressure of the external environment, so that the liquid in the liquid storage cavity 3 opens the water outlet plug 5 and discharges outward due to the internal and external air pressure difference, which is extremely inconvenient to use. The exhaust groove 9 on the water inlet plug 4 is arranged, and when the water inlet plug 4 is closed, the squeezed air in the liquid storage cavity 3 can be discharged from the exhaust groove 9 until the water inlet plug 4 completely covers the water inlet 7. The exhaust groove 9 is blocked by the water inlet 7 or the water inlet plug 4 to achieve the sealing of the liquid storage cavity 3 and the balance of the internal and external air pressures. The liquid in the liquid storage cavity 3 will not automatically flow out from the water outlet 8.

[0027] Preferably, a first sealing layer 10 is provided at the end of the exhaust groove 9. When the water inlet plug 4 is installed to a preset position, the first sealing layer 10 blocks the water inlet 7 to keep the liquid storage chamber 3 sealed.

[0028] In this embodiment, a second sealing layer 11 is further provided on the water inlet plug 4. The first sealing layer 10 and the second sealing layer 11 both protrude outward along the side of the water inlet plug 4, and an annular groove 12 is formed between the first sealing layer 10 and the second sealing layer 11. The edge of the water inlet 7 can be inserted into the annular groove 12, and the first sealing layer 10 and the second sealing layer 11 form seals on the inner and outer sides of the water inlet 7 respectively.

[0029] Preferably, the switch 6 is made of a flexible material, a through hole 13 is provided on the liquid storage chamber 3, and the switch 6 is fixedly mounted on the through hole 13 to block the through hole 13. The switch 6 is pressed to deform into the liquid storage chamber 3, the volume of the liquid storage chamber 3 is reduced, and the gas and liquid inside leave from the water outlet plug 5.

[0030] Specifically, the switch 6 includes a top surface 14 and a side surface 15 . A fixing frame 16 extending outward is provided on the through hole 13 . The side surface 15 of the switch 6 is sleeved on the outside of the fixing frame 16 , and the side surface 15 of the switch 6 is sealed and connected to the fixing frame 16 .

[0031] In this embodiment, a pressing groove 17 is provided on the top of the fixing frame 16, and a step 18 is formed between the pressing groove 17 and the fixing frame 16. The inner surface and the end of the side 15 of the switch 6 are respectively fitted with the pressing groove 17 and the step 18. The inner surface of the side 15 of the switch 6 and the pressing groove 17, and the end of the side 15 of the switch 6 and the step 18 are sealed and fixed by glue.

[0032] Preferably, the top surface 14 of the switch 6 is arc-shaped, and the thickness of the top surface 14 of the switch 6 is smaller than the thickness of the side surface 15 of the switch 6. The arc-shaped setting can increase the volume of the switch 6 that is compressed by deformation. The thickness difference between the top surface 14 and the side surface 15 of the switch 6 can facilitate the deformation of the top surface 14 of the switch 6 under force, thereby preventing the side surface 15 from following the deformation and causing tearing and air leakage between the switch 6 and the fixing frame 16.

[0033] In the above embodiment, in order to facilitate the replacement of the brush head 2 and the replacement of brush heads 2 of different styles, the brush handle 1 and the brush head 2 are detachably connected, and the brush head 2 is provided with a drainage hole 19 at the position corresponding to the water outlet 8. The drainage hole 19 passes through the brush head 2 in the up and down directions. When cleaning, the liquid in the liquid storage chamber 3 can flow to the brush head 2 or the surface to be cleaned.

[0034] In this embodiment, the top of the liquid storage chamber 3 is closed, and a connecting head 20 is provided on the outer side of the top of the liquid storage chamber 3. An extension rod 21 is detachably connected to the connecting head 20. The setting of the extension rod 21 can extend the length of the brush handle 1, which is convenient for users to brush the floor or brush the windows. Before and after the installation of the extension rod 21, the liquid storage chamber 3 is always closed and the liquid can be pressed outward.

[0035] In the above embodiment, the water outlet plug 5 is made of soft rubber and is provided with a cross groove 22. The edge of the cross groove 22 forms blades 23. When the blades 23 are closed, the liquid cannot flow out of the cross groove 22. When the switch 6 is pressed, the liquid exerts force outward, causing the blades 23 to fold in shape, the cross groove 22 to enlarge, and the liquid can flow out.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
