Further, the tail of the liquid outlet 44 is an opening 442, the opening 442 communicates with the liquid outlet 43, the head 443 is made of elastic soft material, and a closed slit 444 is arranged in the middle of the head 443 After receiving a certain pressure from the liquid in the opening 442, the slit 444 will open.

Further, the liquid outlet hole 43 is arranged on the same side of the brush head 4, so that the cleaning liquid is discharged on the same side of the brush head 4, and the cleaning liquid can be better accurately sprayed to the parts to be cleaned.

Concrete use process and principle of the present invention are as follows.

Before the initial use, the present invention is placed vertically, and the ventilation screw 13 is unscrewed, so that the atmosphere communicates with the hollow part in the hand-held part 1 . Open the stopper cover 32, use tools such as a funnel to drain the cleaning solution into the liquid storage tank 3. Under the effect of gravity, the cleaning liquid enters into the middle hole 21 through the connecting pipe 34 and the one-way valve 35 respectively. The gravity cannot overcome the elastic force at the slit 444 of the liquid outlet 44 and pushes away the opening of the head 443 of the liquid outlet 44. The slit 444 allows the gas or liquid in the infusion channel 42 to flow out from the liquid outlet 44 . When the liquid level of the cleaning liquid in the liquid storage tank 3 reaches the highest level, stop adding the cleaning liquid. At this time, the liquid level of the cleaning liquid in the liquid storage tank 3 is as high as that in the middle hole 21 , and there will be a small amount of air in the lower part of the middle hole 21 and in the infusion channel 42 . Tighten the ventilation screw 13 to separate the atmosphere from the hollow part in the handle 1 . ready for use.

When cleaning sanitary utensils, the side of the brush head 4 with the liquid outlet hole 43 is aimed at the part to be cleaned. In use, it includes a gripping process and a loosening process.

Clenching process: Slowly grip and squeeze the elastic ring 14, so that the elastic ring 14 shrinks inwardly, the air in the elastic ring 14 is squeezed, the volume shrinks, and the pressure increases. The gas in the hollow part communicates with each other, and the gas pressure in the hollow part of the hand-held part 1 increases, pushing the liquid level of the cleaning liquid in the middle hole 21 to drop. The one-way valve 35 can only allow the liquid to flow from the connecting pipe 34 to the middle hole 21, so the cleaning liquid cannot flow from the middle hole 21 to the connecting pipe. The cleaning liquid in the middle hole 21 pushes the air or liquid in the lower part of the middle hole 21 and the infusion channel 42 , so that the air or liquid flows from the liquid outlet hole 43 to the liquid outlet 44 . At this time, the air or liquid with a certain pressure pushes away the slit 444 of the head 443 of the liquid outlet 44, and sprays to the part to be cleaned.

Loosening process: loosen the elastic ring 14, the elastic ring 14 expands outward under the action of elasticity, the air volume in the elastic ring 14 expands, the pressure becomes smaller, and a negative pressure is formed when it is lower than the atmospheric pressure. The hole 15 connects the air in the elastic ring 14 with the air in the hollow portion of the handle 1 , so that the air pressure in the middle hole 21 is a negative pressure. Under the action of atmospheric pressure, the air enters the liquid storage tank 3 from the ventilation check valve 33 to push the cleaning liquid, and enters into the middle hole 21 through the communication pipe 34 and the check valve 35 respectively. Gravity cannot overcome the elastic force at the slit 444 of the liquid outlet 44 , but pushes away the slit 444 of the head 443 of the liquid outlet 44 , so that the gas or liquid in the infusion channel 42 flows out from the liquid outlet 44 . Until the air pressure in the middle hole 21 and the air pressure in the liquid storage tank 3 reach equilibrium.

During the cleaning process, repeat the tightening process and loosening process. It is ejected at a certain speed from the liquid outlet, and the parts to be cleaned that are not soaked in water are directly and accurately contacted by the cleaning liquid quantitatively, and the cleaning process is easy to complete; and the parts soaked in water can also be sprayed by the cleaning liquid. The concentration of the cleaning solution at this part can quickly meet the requirements, and the bristles on the brush head can be used to clean quickly, so as to achieve the purpose of accurately injecting the cleaning solution and save the amount of cleaning solution.

When the amount of cleaning liquid is sprayed to a certain amount, hold the handle 1 tightly to make the brush head 4 scrub the cleaning part.

When it is observed from the liquid level mirror 36 that the liquid level in the liquid storage tank 3 is lower than the stored liquid level, the plugging cover 32 is opened to add cleaning liquid.

When not in use for a long time, open the ventilation screw 13 of the baffle plate 12 and the ventilation screw 45 at the bottom of the brush head 4 to drain the cleaning liquid in the system.

The foregoing embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made according to the structures, shapes and principles of the present invention shall be covered by the protection of the present invention. within range.
