Description

Technical Field

[0001] The utility model relates to the technical field of cleaning machines, in particular to a negative pressure shunt structure of a plasma cleaning machine. Background Art

[0002] Plasma cleaning machine is a high-tech technology that uses plasma to achieve effects that conventional cleaning methods cannot achieve. Plasma is a state of matter, also called the fourth state of matter, and does not belong to the common three states of solid, liquid and gas. Applying enough energy to the gas to ionize it will become a plasma state, and the properties of the active components are used to treat the sample surface, thereby achieving the purpose of cleaning, coating, etc.

[0003] Among them, the patent publication number "CN213591285U" records a "plasma cleaning machine", which includes a cleaning machine body, a first cavity, a lifting device and a limiting device. The first cavity is installed in the cleaning machine body and is used to clean the material to be cleaned. The lifting device can drive the first cavity to do lifting and lowering movements. The limiting device is used to limit the first cavity after the lifting device lifts the first cavity. The plasma cleaning machine disclosed in this patent can solve the technical problem that in some plasma cleaning machines, it is not very convenient for the staff to clean and maintain its reaction cavity.

[0004] However, this type of plasma cleaning machine still has certain problems during use, such as:

[0005] Plasma cleaning machines may produce residual cleaning liquid during cleaning and maintenance. If a liquid discharge structure is not provided, the liquid generated in the cavity cannot be discharged smoothly, which is not conducive to the cleaning and long-term use of the cavity. In addition, particulate residues may be generated in the cavity during the cleaning process, and direct discharge during cleaning will cause pollution to the environment. Utility Model Content

[0006] The utility model aims to provide a negative pressure shunt structure for a plasma cleaning machine to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a negative pressure diversion structure of a plasma cleaning machine, comprising a water tank, a vacuum pipe connected to the top of the water tank, a negative pressure pump fixedly connected to the other end of the vacuum pipe, a water inlet fixedly connected to the top of one side of the water tank, a one-way water stop valve threadedly connected to the water inlet for one-way flow toward the water tank, a water inlet pipe threadedly connected to the other end of the one-way water stop valve, a water outlet fixedly connected to the bottom of the other side of the water tank, a filter cover threadedly connected to the inner side of the water outlet, a ball valve threadedly connected to the outer side of the water outlet, and a water outlet pipe threadedly connected to the other end of the ball valve.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 3 The utility model provides a negative pressure diversion structure of a plasma cleaning machine, including a water tank 100, a suction pipe 110 is connected to the top of the water tank 100, the other end of the suction pipe 110 is fixedly connected to a negative pressure pump 200, a water inlet 120 is fixedly connected to the top of one side of the water tank 100, a one-way water stop valve 121 is threadedly connected to the water inlet 120, the other end of the one-way water stop valve 121 is threadedly connected to a water inlet pipe 122, a water outlet 130 is fixedly connected to the bottom of the other side of the water tank 100, a filter cover 131 is threadedly connected to the inner side of the water outlet 130, a ball valve 132 is threadedly connected to the outer side of the water outlet 130, and the other end of the ball valve 132 is threadedly connected to a water outlet pipe 133.

[0026] In a specific embodiment, the negative pressure pump 200 is turned on to evacuate the gas in the water tank 100 to put the water tank 100 in a negative pressure state, and the liquid in the cleaning box of the plasma cleaning machine is sucked into the water tank 100 along the water inlet pipe 122. The ball valve 132 is opened, and the liquid is discharged along the water outlet 130, which is convenient for the discharge of the residual cleaning liquid in the plasma cleaning machine, is beneficial for the cleaning and maintenance of the cleaning box, and increases the practicality of the negative pressure shunt structure. At the same time, when the liquid passes through the filter cover 131, it effectively prevents the solid pollutants in the liquid from being directly discharged to pollute the environment. After the drainage is completed, the filter cover 131 is removed to clean the pollutants, further increasing the practicality of the negative pressure shunt structure.

[0027] See also Figure 1 to Figure 2 The one-way water stop valve 121 opens unidirectionally toward the water tank 100, and the end of the water inlet pipe 122 is provided with an external thread 123 threadedly connected to the cleaning box of the plasma cleaning machine.

[0028] In a specific embodiment, during normal drainage, sewage flows into the water tank 100 unimpeded through the one-way water stop valve 121. When the ball valve 132 is closed or the water outlet 130 is blocked and the water storage height in the water tank 100 exceeds the water inlet 120, the sewage in the water tank 100 cannot flow into the plasma cleaning machine through the one-way water stop valve 121, effectively preventing sewage from flowing back and polluting the plasma cleaning machine again, thereby increasing the practicality of the negative pressure diversion structure.

[0029] See also Figures 1 to 3 , a detachable filter screen 134 is embedded inside the filter cover 131;

[0030] In a specific embodiment, after drainage is completed, the filter cover 131 is removed from the water outlet 130, the filtered pollutants are cleaned and the filter screen 134 is replaced according to actual usage, which is simple and convenient and increases the convenience of the negative pressure diversion structure.

[0031] See also Figure 1 A vertical long strip observation port 140 is provided on the front of the water tank 100 , and a sealing glass 141 is embedded in the observation port 140 .

[0032] In a specific embodiment, the drainage condition of the water tank 100 can be observed in real time through the observation port 140, and the situation of poor drainage or inability to drain can be discovered and solved in time, thereby ensuring cleaning and drainage efficiency and increasing the practicality of the negative pressure diversion structure.

[0033] Working principle: Before use, check whether the connections of each part are tight. First, close the ball valve 132. At this time, the water tank 100 is in a sealed state. Connect the negative pressure shunt structure to the cleaning box of the plasma cleaning machine through the external thread 123 at the end of the water inlet pipe 122. Then start the negative pressure pump 200 to extract the gas in the water tank 100. At this time, the water tank 100 is in a negative pressure state. Under the action of the air pressure difference, the liquid in the cleaning box flows into the water tank 100 along the water inlet pipe 122 through the one-way water stop valve 121, which is convenient for cleaning and maintaining the cleaning box of the plasma cleaning machine, and increases the practicality of the negative pressure shunt structure. The water storage volume in the water tank 100 is monitored in real time through the observation port 140. When the water absorption is completed or the water storage height is about to be higher than the water inlet 120, open the ball valve 132 to discharge the liquid. If the water volume is higher than the water inlet 120, the water in the water tank 100 is blocked by the one-way water stop valve 121 and cannot flow back, which effectively avoids secondary pollution of the plasma cleaning machine and further enhances the practicality of the negative pressure shunt structure. After the drainage is completed, the ball valve 132 is unscrewed from the water outlet 130, the filter cover 131 is unscrewed from the water outlet 130, the filtered debris is cleaned, and the filter screen 134 is replaced according to the actual use. In addition, during the drainage process, if the water volume is found to decrease very slowly or stop through the observation port 140, it is considered whether the water outlet 130 is blocked, and the filter cover 131 can be cleaned in time to ensure smooth drainage. After use, the negative pressure diversion structure can be separated from the plasma cleaning machine and stored separately.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
