[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0024] See Figures 1-7 A sealing machine for an integrated water tank, comprising a machine body 1, wherein the sealing machine includes: The chamber assembly 2 is mounted on the machine body 1 and is used for vacuum sealing. When the chamber assembly 2 is in the open state, it allows the part to be sealed to enter. When the chamber assembly 2 is in the closed state, it forms a working chamber so that the sealing machine can vacuum seal the part to be sealed. The cleaning water tank 5 is integrated on the body 1. The cleaning water tank 5 is connected to the chamber assembly 2 and provides cleaning fluid to the working chamber for cleaning.

[0025] The chamber assembly 2, cleaning water tank 5, and water box assembly 6 inside the machine body 1 are connected in sequence to form a liquid cleaning flow path. Automatic cleaning of the chamber assembly 2 can be achieved without disassembling the chamber assembly, solving the problem of manual disassembly and cleaning required by existing sealing machines due to the lack of cleaning function.

[0026] The sealing machine includes a water discharge solenoid valve 4, with its two ends connected to the chamber assembly 2 and the cleaning water tank 5, respectively. The water discharge solenoid valve 4 is installed inside the machine body 1.

[0027] The sealing machine includes an air pump 3, which is connected to the chamber assembly 2; The sealing machine has a vacuuming operation and a cleaning operation. The air pump 3 is configured to evacuate the working chamber to vacuum the parts to be sealed when the chamber assembly 2 is closed during the vacuuming operation, and is configured to evacuate the working chamber to draw the cleaning liquid in the cleaning water tank 5 into the working chamber when the chamber assembly 2 is closed during the cleaning operation. The air pump 3 is located inside the machine body 1.

[0028] The air pump 3 works in conjunction with the vacuum circuit to achieve the original vacuuming function of the sealing machine, while the drain solenoid valve 4 provides on / off control for the liquid cleaning flow path. The two work together without interference. When the air pump 3 operates, creating negative pressure between the chamber assembly 2 and the water box assembly 6, the drain solenoid valve 4 opens, using the negative pressure suction to guide the liquid in the cleaning water tank 5 towards the chamber assembly 2 and the water box assembly 6. This design eliminates the need for an additional power unit, allowing vacuuming and liquid flow to be achieved using a single air pump 3. The negative pressure of the vacuum pump enables the cleaning fluid to flow, resulting in a compact and energy-efficient structure. It also integrates vacuuming and automatic cleaning functions, enhancing the equipment's versatility and ease of use.

[0029] The sealing machine includes a water box assembly 6 for receiving liquid to prevent liquid from entering the air pump 3. The chamber assembly 2, the water box assembly 6, and the air pump 3 are connected in sequence to form a vacuum path so that the liquid drawn from the chamber assembly 2 enters the water box assembly 6 without reaching the air pump 3.

[0030] The water tank assembly 6 is used to collect the liquid from the flow cleaning chamber assembly 2, as well as the liquid that enters during vacuuming, preventing the liquid from directly entering the air pump 3 during vacuuming. When the air pump 3 is vacuuming, the gas flows to the air pump 3 through the chamber assembly 2 and the water tank assembly 6. Therefore, when there is liquid in the vacuuming path, the liquid is inside the water tank assembly 6 and cannot easily bypass the water tank assembly 6 to enter the air pump 3.

[0031] The sealing machine includes a pneumatic solenoid valve 7 for switching the chamber assembly 2 from a closed state to an open state. The pneumatic solenoid valve 7 is connected to the water box assembly 6 and / or the working chamber of the chamber assembly 2, and is located inside the machine body 1.

[0032] The water tank assembly 6 is equipped with a water tank liquid sensor for detecting the internal liquid level. The water tank assembly 6 includes a housing 604 and a water tank 605. The housing 604 is integrally formed with the body 1, or the housing 604 is detachably connected to the body 1. The water tank liquid sensor is disposed on the housing 604 or the water tank 605.

[0033] The water box assembly 6 is provided with a first end 601, a second end 602 and a third end 603; the first end 601 is connected to the input end of the air pump 3, the second end 602 is connected to the output end of the air solenoid valve 7, the input end of the air solenoid valve 7 is connected to the outside of the water box assembly 6, and the third end 603 is connected to the chamber assembly 2. When the water box assembly 6 returns from a negative pressure state to a positive pressure state, the air pump 3 stops running, the air solenoid valve 7 opens, and the gas enters the water box assembly 6 through the air solenoid valve 7. The first end 601, the second end 602 and the third end 603 are all mounted on the outer shell 604, and the water box 605 is detachably installed inside the outer shell 604.

[0034] The liquid level sensor in the water tank can detect the liquid level inside the water tank assembly 6 in real time, preventing overflow due to excessive liquid inside the assembly 6. When the liquid level sensor is mounted on the housing 604, the probe of the liquid level sensor is aligned with the water tank 605 (the probe of the liquid level sensor faces inwards towards the water tank 605) to avoid interference during the installation and removal of the water tank 605. The liquid level sensor is mounted on the upper part of the housing 604 via a spring-loaded elastic extension and retraction mechanism. The water tank 605 is equipped with a guide slope to guide the extension and retraction of the liquid level sensor during installation and removal. The housing 604 has an installation chamber where the liquid level sensor is confined. The installation chamber has a through hole for the probe of the liquid level sensor to extend out, and a sealing plate is provided on the upper part of the installation chamber. The sealing plate is fixed with screws to allow the liquid level sensor and spring to be installed inside the installation chamber.

[0035] When the liquid sensor in the water tank is installed on the water tank 605, the probe of the liquid sensor must be located inside the water tank 605. The lower part of the liquid sensor is sealed to the water tank 605 through a sealing ring, etc. The bottom of the liquid sensor is provided with a first power terminal, and the housing 604 is provided with a second power terminal. The second power terminal is electrically connected to the machine control device. After the water tank 605 is installed in place (the water tank 605 can no longer be pushed into the housing 604), the second power terminal makes conductive contact with the first power terminal.

[0036] The cleaning water tank 5 is equipped with a water tank liquid sensor for detecting the internal liquid level. The cleaning water tank 5 is integrally formed with the body 1, or the cleaning water tank 5 is detachably connected to the body 1.

[0037] The water tank liquid sensor inside the cleaning water tank 5 can detect the internal liquid level in real time, accurately reflecting the water shortage or fullness status, thus preventing cleaning from failing due to water shortage in the cleaning water tank 5. When the cleaning water tank 5 is integrally molded with the body 1, the structure is highly stable and has good sealing performance, preventing cleaning fluid leakage; the detachable connection design allows the cleaning water tank 5 to be removed separately. This technical solution preferably integrates the cleaning water tank 5 with the body 1. The cleaning water tank 5 has a mounting position 501 for installing the water tank liquid sensor. The probe of the water tank liquid sensor is located inside the cleaning water tank 5, with the lower part of the water tank liquid sensor inserted into the mounting position 501, and a sealed connection (through a sealing ring, sealant, etc.) between the two to prevent water leakage.

[0039] The open design at the top of the cleaning water tank 5 facilitates quick addition of water and cleaning agents, making operation intuitive and convenient. The cover 8 can be detachably installed in the open position of the cleaning water tank 5, effectively preventing external dust and impurities from entering the interior of the cleaning water tank 5. When the cover 8 is removed, liquid can be added to the cleaning water tank 5.

[0040] Alternatively, the cover 8 can be rotatably or slidably installed in the open position of the cleaning water tank 5. The cover 8 is hinged to the body 1, and the cover 8 rotates to open and close the upper opening of the cleaning water tank 5. The body 1 has a sliding groove, and the two sides of the cover 8 are inserted into the sliding groove, allowing the cover 8 to slide to open and close the upper opening of the cleaning water tank 5. This technical solution preferably uses the cover 8 placed directly in the open position of the upper part of the cleaning water tank 5. The top of the cleaning water tank 5 has a positioning groove, and the cover 8 is detachably installed in the positioning groove.
