[0037] Please refer to Figure 1 and Figure 2 This embodiment provides a waste liquid collection box, including a box body 100, a suction pipe 200, a funnel 300, and a liquid level connection pipe 600;
[0038] The housing 100 has an inner cavity 101; a pipette connector 500 is provided on the housing 100;
[0039] Along the length of the suction tube 200, the suction tube 200 includes a first end 210 and a second end 220 opposite to each other; the tube body of the suction tube 200 is sealed to the box 100, the first end 210 is located outside the box 100, and the second end 220 extends into the inner cavity 101.
[0040] The top of the funnel 300 is mounted on the box 100, the funnel 300 is connected to the inner cavity 101, and a plug 310 is detachably mounted on the bottom opening of the funnel 300.
[0041] The liquid level connecting pipe 600 is sealed to the tank 100. The top of the liquid level connecting pipe 600 is located at the top of the tank 100, and the bottom of the liquid level connecting pipe 600 is located at the bottom of the tank 100. The liquid level connecting pipe 600 is located outside the tank 100. Multiple liquid level windows 601 are provided on the liquid level connecting pipe 600.
[0042] The waste liquid collection tank in this design uses a siphon principle to draw in or discharge waste liquid via a suction pipe 200. A funnel 300 facilitates timely and efficient emptying of the waste liquid from the tank 100. A pipette connector 500 is installed on the tank 100, which can be connected to a bidirectional pipette pump to inject and discharge liquid into and from the tank 100. A level window 601 on the level connection pipe 600 allows for easy observation of the liquid level within the tank 100. The tank 100 is also easily mounted on a fire truck chassis. Thus, the waste liquid collection tank offers advantages such as simple structure and ease of assembly and maintenance.
[0043] It should be noted that the pipetting connector 500 in this solution refers to the connector that connects to the pipetting pump. The specific structure and dimensions of the connector are not limited here, as long as the pipetting connector 500 can connect to the pipetting pump. (The specific product selection may include threaded connectors, quick-release connectors, etc.)
[0044] Please continue reading. Figure 1 , Figure 2 , Figure 3 and Figure 4 To understand more structural details of the waste liquid collection tank. In an optional embodiment, the tank body 100 includes a cylindrical body 110 and tank covers 120 disposed at both ends of the cylindrical body 110; the cylindrical body 110 and the tank covers 120 enclose an inner cavity 101. Such a tank body 100 has the advantages of simple structure, convenient installation, and lower cost. Optionally, the tank body 100 is cylindrical. It is easy to understand that in other embodiments of this utility model, the tank body 100 can also be cuboid, etc., which is only an example here and is not limited to any specific embodiment.
[0045] In this embodiment, the inner cavity 101 is a sealed structure. This ensures the sealing performance of the housing 100, thereby guaranteeing the safety and reliability of waste liquid collection.
[0046] Optionally, the suction pipe 200 and the liquid level connection pipe 600 are both arranged along the radial direction of the tank 100. This allows the pipes to be installed on the tank 100 with the shortest path, which shortens the length of the pipes and thus provides better suction and drainage.
[0047] As can also be seen from the figure, in an optional embodiment, the second end 220 of the suction tube 200 is directly opposite the funnel 300. This allows the suction tube 200 to enter the bottom of the housing 100 in a timely and efficient manner, while also reducing the impact on the housing 100 when waste liquid is injected into the inner cavity 101 from the second end 220; on the other hand, this arrangement also facilitates the rapid drainage of liquid by the suction tube 200 through the funnel 300.
[0048] In an optional embodiment, the second end 220 extends below the top opening of the funnel 300. That is, waste liquid is first injected into the funnel 300 from the second end 220 of the suction tube 200, and then flows from the funnel 300 to other locations in the inner cavity 101. This reduces the impact during waste liquid injection and ensures efficient liquid suction and discharge.
[0049] As can also be seen from the figure, in an optional embodiment, the liquid level connecting pipe 600 includes a first bend 610, a straight pipe 630, and a second bend 620 connected in sequence; the first bend 610 is located at the top of the tank 100, and the second bend 620 is located at the bottom of the tank 100; the straight pipe 630 is located on one side of the length direction of the tank 100. This arrangement can ensure the stability of the waste liquid in the liquid level connecting pipe 600, thereby ensuring accurate observation of liquid level changes at the liquid level window 601.
[0050] In an optional embodiment, all level windows 601 are located on straight pipes 630. The straight pipes 630 are arranged radially along the tank 100. This ensures that the tank 100 is arranged vertically, thereby guaranteeing that the level windows 601 accurately display the current level within the tank 100. Multiple level windows 601 are evenly spaced on the straight pipes 630.
[0051] Furthermore, in an optional embodiment, the first bend 610 and the second bend 620 are arranged symmetrically to each other. This ensures the stability and reliability of the liquid in the liquid level connection pipe 600.
[0052] In an optional embodiment, the waste liquid collection tank further includes a baffle plate 700; the baffle plate 700 is disposed in the inner cavity 101, and the baffle plate 700 divides the tank body 100 into a left chamber 103 and a right chamber 104; the suction pipe 200, the funnel 300, and the liquid level connecting pipe 600 are all disposed on the left chamber 103 of the tank body 100.
[0053] During use, the liquid level window 601 is connected to the connecting pipe, allowing for continuous observation of the liquid level within the tank 100. A bidirectional pipette pump is connected to the top of the tank 100 via a threaded pipette connector 500. The suction pipe 200 uses a siphon principle to draw in and discharge waste liquid. A funnel 300 is located at the bottom of the tank 100; to drain the waste liquid, the plug 310 installed below the funnel 300 is removed. A baffle 700 is installed inside the tank 100 to reduce lateral movement of waste liquid within the tank 100 during vehicle traffic. This waste liquid collection tank is mounted on the chassis of a fire truck. It features a simple structure, facilitating assembly and maintenance.
[0054] Secondly, this utility model provides a fire-fighting equipment, which includes the waste liquid collection tank of any of the foregoing embodiments. Such fire-fighting equipment can achieve simple and efficient treatment of waste liquid.
[0055] In summary, this utility model embodiment provides a waste liquid collection tank and fire-fighting equipment, which has at least the following advantages:
[0056] The suction pipe 200 uses a siphon principle to draw in or discharge waste liquid. The funnel 300 facilitates timely and efficient emptying of the waste liquid from the tank 100. The pipette connector 500 can be connected to a bidirectional pipette pump, enabling the injection and discharge of liquid into and from the tank 100. The level window 601 on the level connection pipe 600 allows for easy observation of the liquid level within the tank 100. Furthermore, the tank 100 is easily mounted on a fire truck chassis. In summary, this waste liquid collection tank offers advantages such as simple structure and ease of assembly and maintenance.
[0057] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
