Description

Technical Field

[0001] This utility model relates to the field of automotive maintenance device technology, specifically a car wash bottle. Background Technology

[0002] Currently, most commercially available car wash bottles typically consist of a bottle body and a cap connected to the bottle body. The cap has an inflation valve and a spray nozzle. Users inflate the bottle with compressed air through the inflation valve to build up pressure. The spray nozzle connects to a spray gun via a high-pressure flexible tube, and the pressure difference forces the cleaning fluid to be sprayed out through the spray gun. However, these existing car wash bottles have several significant drawbacks in practical use:

[0003] First, the liquid absorption efficiency is low and the residue is large. Traditional suction tubes are usually straight tubes with a flat cut at the bottom and do not fit the inner surface of the bottle bottom. When the liquid level in the bottle is low, the suction tube cannot effectively absorb the liquid that has gathered at the lowest point of the bottle bottom, resulting in a large amount of cleaning liquid residue and waste. In addition, the liquid residue at the bottom of the bottle often accumulates undissolved particles drawn in from the outside or separated from the cleaning agent. These impurities can easily clog the suction tube or the downstream nozzle, affecting normal use. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a car wash bottle that improves liquid utilization, reduces residue, filters cleaning fluid, and breaks up foam in the cleaning fluid to ensure stable spraying.

[0005] The technical solution adopted by this utility model to achieve the above-mentioned objective is as follows: a car wash bottle, including a bottle body and a bottle cap threadedly connected to the bottle body. An inflation valve, a spray connector, a pressure relief valve, and a pressure gauge are fixedly connected to the bottle cap. A suction tube is fixedly connected to the bottle cap and communicates with the spray connector. The suction tube extends into the bottle body. The inner bottom surface of the bottle body is provided with an inverted frustum-shaped liquid collection groove. A filter cylinder is fixedly connected to the bottom end of the suction tube. The bottom surface of the filter cylinder abuts against the bottom surface of the liquid collection groove.

[0006] In the above technical solution, the specific structure of the bottle cap is as follows:

[0007] The bottle cap includes a threaded connection part and a cap body fixedly connected to the threaded connection part. The threaded connection part is threadedly connected to the bottle mouth of the bottle body. An inflation valve, a spray connector, a pressure relief valve, and a pressure gauge are fixedly connected to the cap body.

[0008] In the above technical solution, the cap body is provided with four sets of mounting surfaces;

[0009] The bottle cap is provided with an inflation channel that mates with a set of mounting surfaces, and the inflation valve is connected to the inflation channel.

[0010] One set of the mounting surfaces is fitted with a pressure relief channel, and the pressure relief valve is connected to the pressure relief channel;

[0011] One set of the mounting surfaces is equipped with a liquid outlet channel, the liquid outlet channel is connected to the spray connector, and the liquid suction pipe is connected to the liquid outlet channel;

[0012] One of the mounting surfaces is equipped with a pressure channel, and the pressure gauge works in conjunction with the pressure channel to achieve pressure measurement.

[0013] Furthermore, the liquid outlet channel is located at the center of the bottle cap.

[0014] In the above technical solution, in order to facilitate the disassembly and assembly of the suction tube, the top end of the suction tube is provided with a threaded mounting part, and the threaded mounting part is threadedly connected to the liquid outlet channel;

[0015] Furthermore, to ensure the sealing of the suction tube connection, a sealing platform is fixedly connected to the bottom of the threaded mounting part on the suction tube, and a sealing ring is fixedly connected to the sealing platform, with the sealing ring abutting against the bottom surface of the threaded connection part.

[0016] The beneficial effects of this utility model are as follows: The bottom of the bottle body is provided with a liquid collection tank with an inverted frustum shape, and the bottom end of the suction tube is fixedly connected to a filter cylinder. The filter cylinder is located in the liquid collection tank, so that the liquid in the bottle can be sucked out to the maximum extent through the central suction tube regardless of any tilt angle, which improves the utilization rate of the liquid, reduces residue, and the filter cylinder can effectively intercept impurities or undissolved particles in the cleaning liquid, prevent clogging of the subsequent spray gun, ensure smooth spraying, and extend the service life of the equipment. The filter cylinder can also break up the foam in the cleaning liquid, ensuring that the liquid jet sprayed from the spray gun is stable and continuous, making the cleaning operation more precise and efficient.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] Please see Figures 1-8 A car wash bottle mainly includes a bottle body 100 and a bottle cap 200. The bottle cap 200 is detachably installed on the bottle mouth of the bottle body 100 by means of a threaded connection, so as to facilitate the filling of the bottle body 100 with cleaning fluid.

[0034] First of all, the bottle cap 200 is an integrated functional module with four core components fixedly installed on it, namely the inflation valve 300, the injection connector 400, the pressure relief valve 500 and the pressure gauge 600. Among them, the inflation valve 300 is used to connect to an external air source to fill the sealed bottle body 100 with compressed air to establish working pressure.

[0035] The spray connector 400 is used to connect an external spray gun or hose (the hose is then connected to the spray gun) as a channel for the outflow of cleaning fluid.

[0036] As a key safety device, the pressure relief valve 500 automatically opens when the pressure inside the bottle exceeds the preset safety threshold to release excess pressure and ensure safe use.

[0037] The pressure gauge 600 is used to display the pressure value inside the bottle in real time, making it convenient for users to monitor and adjust.

[0038] Furthermore, the bottle cap 200 includes a threaded connection part 201 that is threadedly connected to the bottle mouth of the bottle body 100, and a cap body 202 fixed on the threaded connection part 201. The cap body 202 has four independent mounting surfaces 203, which are used to assemble the above four core components and communicate with their respective internal channels.

[0039] Specifically, the bottle cap 200 is provided with an inflation channel 204 that mates with a set of mounting surfaces 203, and the inflation valve 300 is connected to the inflation channel 204, so that external gas can enter the bottle through the inflation valve 300.

[0040] The bottle cap 200 is fitted with another set of mounting surfaces 203 and is provided with a pressure relief channel 205. The pressure relief valve 500 is connected to the pressure relief channel 205, forming a release path for high-pressure gas.

[0041] The bottle cap 200 is provided with a liquid outlet channel 206 in cooperation with the third set of mounting surfaces 203. The liquid outlet channel 206 is connected to the spray connector 400. In particular, the liquid outlet channel 206 is preferably located at the center of the bottle cap 200.

[0042] The bottle cap 200 is fitted with the fourth mounting surface 203 and has a pressure channel 207. The sensing end of the pressure gauge 600 is fitted with the pressure channel 207 to accurately measure the gas pressure inside the bottle.

[0043] Secondly, in order to connect the liquid inside the bottle cap 200 and the bottle body 100, a suction tube 700 is fixedly connected to the bottle cap 200. The top end of the suction tube 700 is provided with a threaded mounting part 701, which is tightly threaded into the liquid outlet channel 206 through the threaded mounting part 701, realizing the flow channel connection between the suction tube 700 and the spray connector 400. This threaded connection method facilitates the installation and disassembly of the suction tube 700 and is conducive to daily maintenance and cleaning.

[0044] To further ensure the sealing of the connection, a sealing platform 702 extending radially outward is fixedly provided on the suction tube 700 below the threaded mounting part 701. A sealing ring 703 is fixedly embedded on the top surface of the sealing platform 702. When the suction tube 700 is fully screwed into the liquid outlet channel 206, the sealing ring 703 forms a tight end face contact seal with the lower surface of the threaded connection part 201 of the bottle cap 200, effectively preventing liquid and gas under high pressure from leaking from the connection.

[0045] The bottom end of the above-mentioned suction tube 700 extends to the bottom of the bottle body 100. On the inner bottom surface of the bottle body 100, there is a downwardly recessed inverted frustum-shaped liquid collection groove 101. The structure of the liquid collection groove 101 helps to collect the remaining liquid in the bottle to the lowest point at the center of its bottom.

[0046] In addition, a filter cylinder 704 is fixedly connected to the bottom end of the suction pipe 700. The bottom surface of the filter cylinder 704 abuts against the bottom surface of the collection tank 101, so that the cleaning liquid inside the bottle 100 must pass through the filter cylinder 704. The filter cylinder 704 itself is made of porous filter material. Its pore size allows liquid to pass through but can effectively intercept solid particulate impurities. When the user pressurizes the bottle through the inflation valve 300, the cleaning liquid is drawn into the filter cylinder 704 from the bottom of the collection tank 101 under pressure. When flowing through the filter cylinder 704, impurities in the liquid are filtered. At the same time, if the cleaning liquid generates foam due to shaking or other reasons, the foam will be sheared and squeezed and broken when forced to pass through the dense filter structure of the filter cylinder 704, and will be reduced to liquid and gas, thereby effectively eliminating the adverse effect of foam on spray stability.

[0047] The working principle of this invention is as follows: The user first opens the bottle cap 200, injects the diluted cleaning solution into the bottle body 100, then tightens the bottle cap 200, and fills the bottle with compressed air through the inflation valve 300, observing the pressure gauge 600 until the required working pressure is reached. Then, the inflation valve 300 is closed. When the pressure is too high, the pressure relief valve 500 will automatically activate to ensure safety. After that, the spray gun or hose is connected to the spray connector 400, and the spray gun switch is turned on. The pressurized cleaning solution in the bottle is then drawn into the filter cartridge 704 from the bottom of the collection tank 101. After filtration and defoaming, a stable liquid flow is formed and sprayed out. During the entire use process, the pressure gauge 600 can be monitored by the user in real time.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
