Description

Technical Field

[0001] The utility model relates to the technical field of spray nozzles, in particular to a foam spray nozzle with a pressure-boosting function. Background Art

[0002] The cleaning agent and the soluble liquid pass through the bottle tube. During use, the liquid output inside the bottle is converted into foam and sprayed out through the press nozzle adapted to the bottle.

[0003] A Chinese patent discloses a bottled air-conditioning foam cleaning agent (authorization announcement number CN202864069U). The patented technology consists of a pressure bottle and an air-conditioning foam cleaning agent contained in the pressure bottle. The pressure bottle consists of an outer bottle cap, a rotating bottle mouth, an elastic bottle mouth and a bottle body. The rotating bottle mouth consists of a fixed part of the rotating bottle mouth and a rotating part of the rotating bottle mouth. Under the guidance of the screw-in slideway of the fixed part of the rotating bottle mouth, the rotating part of the rotating bottle mouth can move 1 mm to 2 mm along the axial direction of the bottle body. There is an annular groove on the upper part of the bottle body, and a circle of protrusions on the inner wall of the outer bottle cap. The bottle body and the outer bottle cap are covered by the groove of the bottle body and the protrusion of the outer bottle cap. The volume of the air-conditioning foam cleaning agent contained in the pressure bottle is 500 ml to 550 ml; a hose is connected to the elastic bottle mouth, and the hose goes straight to the bottom of the bottle body; a spare curled hose is provided on the inner upper part of the outer bottle cap.

[0004] This patented technology can effectively spray the cleaning agent when used, but there are still some shortcomings during use. The pressure of the pressing structure is uncontrollable, resulting in the output cleaning agent foam having a short distance and a small spraying range after mixing with the cleaning agent and gas. Therefore, technical personnel in this field provide a foam nozzle with a pressurization function to solve the problems raised in the above background technology. Utility Model Content

[0025] 2. Beneficial effects

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] The utility model uses a press-and-spray structure, a piston pressurizing structure and a spring reset structure to squeeze the cleaning agent sucked into the pressure chamber by the piston, and the gas inside the pressure chamber is squeezed out through the gas inside the pressure chamber. The cleaning agent is mixed during the output process to form foam and spray out, thereby spraying the cleaning agent foam on the corresponding position;

[0028] At the same time, the pressure chamber is connected to the air supply pipe. When the cleaning agent is output, the cleaning agent mixed with the gas is pressurized. Increasing the output pressure can ensure that the cleaning agent can be sprayed out at a higher speed and force, thereby enhancing the cleaning effect. During the use of this nozzle, it is very suitable for cleaning particularly stubborn dirt. The high output pressure can make the cleaning liquid cover a wider range, thereby reducing the number of repeated cleaning times and improving the cleaning effect of large areas or difficult-to-access areas.

[0029] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] Example 1

[0045] See also Figure 1-Figure 4 As shown, this embodiment is a foam spray head with a pressurizing function, comprising a bottle body 100,

[0046] The spraying structure 200 is located inside the upper end of the bottle body 100;

[0047] The spraying structure 200 includes a bottle mouth 206, a bottle cap 201 located at the upper end of the bottle body 100 and sleeved on the outer wall of the bottle mouth 206, a suction pipe 202 installed inside the bottle cap 201, a delivery pipe 205 located inside the upper end of the nozzle 203, a piston 208 sleeved on the outer wall of the delivery pipe 205, a valve sleeve 210 fixed to the lower end of the delivery pipe 205, a spring 213 located at the lower end of the valve sleeve 210, a valve ball 212 located at the lower end of the spring 213, a pressure chamber 209 located inside the upper end of the suction pipe 202, a funnel 211 located inside the suction pipe 202, and a nozzle 203 located at one end of the delivery pipe 205;

[0048] The bottle cap 201 is provided with mutually meshing threads at one end opposite to the bottle mouth, and a ring-shaped sealing gasket is provided on the inner wall of the upper end of the bottle cap 201;

[0049] A sliding sleeve 207 is embedded in the upper end of the bottle cap 201, and the delivery tube 205 is slidably installed inside the sliding sleeve 207;

[0050] A gland 204 is provided at the upper end of the delivery pipe 205;

[0051] The pressure chamber 209 is located above the funnel 211, the piston 208 is slidably installed inside the pressure chamber 209, and the valve ball 212 is located at the center of the funnel 211;

[0052] Use of the ejection structure 200;

[0053] The bottle body 100 stores cleaning agent inside. During use, the pressure cap 204 is pressed, and the delivery pipe 205 is slidably installed inside the upper end of the bottle cap 201 through the sliding sleeve 207. The delivery pipe 205 descends longitudinally, and the piston 208 moves longitudinally inside the pressure chamber 209 inside the suction pipe 202. At the same time, the spring 213 is forced to shrink, driving the valve ball 212 to close the funnel 211, and the lower end of the suction pipe 202 is closed. The cleaning agent in the pressure chamber 209 is delivered to the delivery pipe 205 through the valve sleeve 210. The cleaning agent output from the delivery pipe 205 is mixed with the extrusion pressure inside the pressure chamber 209, mixed inside the nozzle 203, and formed into foam to be sprayed out;

[0054] It is worth mentioning that a one-way flow valve group is arranged inside the valve sleeve 210. When the valve sleeve 210 is lifted, the pressure squeezes the valve group to close. When it descends longitudinally, the valve group opens. When the pressure cover 204 is relaxed, the spring 213 loses its squeezing force, and the valve ball 212 closed at the center of the funnel 211 is lifted. The piston 208 rises and the suction force acts on the inside of the pressure chamber 209. The suction force enters the suction tube 202 through the funnel 211, and then enters the inside of the bottle body 100, sucking the cleaning liquid inside the bottle body 100 into the suction tube 202. The cleaning agent remaining in the suction tube 202 is pushed to the pressure chamber 209 for storage, so as to provide cleaning agent for reuse.

[0055] Example 2

[0056] See also Figure 1-Figure 4 As shown, this embodiment is based on the embodiment 1 and also includes; and;

[0057] The pressurizing structure 300 is located at one side of the upper end of the bottle body 100;

[0058] The pressurizing structure 300 includes a gas tank 301 , an air supply pipe 304 located at one side of the bottle mouth 206 and at one end of the gas tank 301 , and a control valve 305 located inside the air supply pipe 304 .

[0059] One end of the air supply pipe 304 passes through the bottle mouth 206, and one end of the air supply pipe 304 passes through the bottle mouth 206 and is located in communication with the pressure chamber 209;

[0060] A pressure gauge 303 is provided at the upper end of the gas tank 301, an injection port 302 is provided at the upper end of the gas tank 301, and a one-way valve is provided inside the injection port 302;

[0061] Performing use of the pressurized structure 300;

[0062] When using the foam spraying device, the process of pressing the piston 208 opens the valve of the air supply pipe 304, and the compressed gas stored in the gas tank 301 is transported to the air supply pipe 304. The air supply pipe 304 transports the pressurized air flow into the pressure chamber 209, and the pressure chamber 209 is additionally pressurized. The pressurized air flow is mixed with the cleaning agent and output. After the output pressure of the cleaning liquid is increased, the cleaning liquid foam covers a wider range, thereby reducing the number of repeated cleaning times. The cleaning agent is more flexible in dealing with different types of dirt or materials. Therefore, it can meet more diverse cleaning needs and is suitable for cleaning large areas or difficult-to-access areas.
