[0002] The current container surface mold cleaning and other oil stain cleaning are realized through manual operation. For example, first, spray cleaning agent, then perform surface wiping and polishing, and finally collect the cleaning waste liquid. The manual operation process is not only time-consuming and laborious, but also unsuitable for cleaning some special containers and occasions with cleaning agent; therefore, manual wiping and polishing not only have low efficiency, but also easily cause mold and dust particles to spread into the air, polluting the air environment.

[0003] In order to overcome the problem of low efficiency of manual wiping, researchers in the relevant field also attempt to design an automatic cleaning device with a brush. This kind of cleaning device can efficiently clean various surfaces through electric drive and the friction of the brush. Moreover, according to different use scenarios and needs, appropriate equipment and brush types can be selected to greatly improve the cleaning effect. However, the brush in the existing automatic cleaning device usually wipes along one direction and cannot simulate the action of manual wiping and polishing, so it is difficult to clean some stubborn stains on the surface of the container, thereby reducing the cleaning effect. SUMMARY

[0014] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0016] AsFigure 1 , Figure 2 ,as well as Figure 3 As shown, a negative pressure sterilization device includes: a power mechanism 10, a cleaner 20, and a filter membrane 30. The power mechanism 10 includes a motor 101, a fan 102, a frame 103, and a housing fitted onto the frame 103; the housing includes a first housing 105 and a second housing 106; the motor 101 is disposed within the frame 103 corresponding to the position of the first housing 105; the fan 102 is disposed within the frame 103 corresponding to the position of the second housing 106; the first output end of the motor 101 is connected to the fan 102. The cleaner 20 passes through the front end of the first housing 105 and is connected to the frame 103 via a sliding shaft 1031, and simultaneously connected to the second output end of the motor 101 via an eccentric shaft 40; the motor 101 can drive the cleaner 20 to reciprocate relative to the frame 103 along the extension direction of the sliding shaft 1031 when the cleaner 20 performs a cleaning task. The filter membrane 30 is wrapped around the second housing 106, which has a mesh structure; the motor 101 can drive the fan 102 to rotate when the cleaner 20 performs a cleaning task; the fan 102 can provide negative pressure to the cleaner 20 by rotating so that the airflow near the cleaner 20 is filtered through the filter membrane 30 and then dispersed into the air.

[0017] When the negative pressure sterilization device is working, firstly, the motor 101 and the fan 102 are installed inside the frame 103; the first output end of the motor 101 is connected to the fan 102, and the second output end is connected to the cleaner 20 through the eccentric shaft 40; at the same time, the cleaner 20 is connected to the frame 103 through the sliding shaft 1031; secondly, the first housing 105 is fitted onto the frame 103 corresponding to the position of the motor 101, and the second housing 106 is fitted onto the frame 103 corresponding to the position of the fan 102; the first housing 105 and the second housing 106 are connected through the frame 103; finally, the filter membrane 30 is fitted onto the mesh-structured second housing 106.

[0018] When the negative pressure sterilization device performs a cleaning task, the motor 101 rotates, driving the cleaner 20 to reciprocate relative to the frame 103 along the extension direction of the sliding shaft 1031. Simultaneously, the fan 102, driven by the motor 101, provides negative pressure to the cleaner 20 to adsorb airflow near the cleaner 20. The adsorbed airflow passes through the first housing 105 and the second housing 106, is filtered by the filter membrane 30 on the second housing 106, and then dispersed into the air. Therefore, the negative pressure sterilization device not only effectively simulates the action of manual wiping, improving the cleaning effect of the container surface, but also allows bacteria and dust particles cleaned by the cleaner to be filtered by the filter membrane, thus achieving a highly efficient and dust-free sterilization effect.

[0019] In the preferred embodiment, the cleaner 20 comprises a brush holder 202 and a brush 201; the brush 201 is detachably mounted on one side of the brush holder 202; the other side of the brush holder 202 is provided with a first through hole 2021 symmetrical in up and down; the front end of the skeleton 103 is provided with a sliding shaft 1031 symmetrical in up and down; the first through hole 2021 of the brush holder 202 is connected to the front end of the skeleton 103 through the sliding shaft 1031.

[0020] Specifically, first, the through hole on the other side of the brush holder 202 is passed through the sliding shaft 1031 of the skeleton 103 to realize the connection of the brush holder 202 and the skeleton 103; then the brush 201 is fixed on one side of the brush holder 202 by screws, thereby facilitating the disassembly of the brush 201 from the brush holder 202, and providing convenience for the replacement of the brush 201.

[0021] As Figure 3 The partial view of the brush driving is shown. The length of the sliding shaft 1031 on the skeleton 103 is greater than the length of the first through hole 2021 on the brush holder. When the motor 101 rotates, it can drive the brush holder 202 to make reciprocating motion on the sliding shaft 1031, so that the brush on the brush holder can simulate the action of manual wiping to repeatedly wipe the surface of the container, thereby improving the cleaning effect of the cleaner on the surface of the container.

[0022] In the preferred embodiment, the skeleton 103 is provided with a cross-section port 1032 at a preset position away from the front end of the skeleton; the first shell 105 is sleeved on the skeleton 103 and connected with the cross-section port 1032 of the skeleton; the second shell 106 is sleeved on the skeleton 103 relative to the first shell 105 and cooperatively connected with the cross-section port 1032 of the skeleton.

[0023] Specifically, the first shell 105 and the second shell 106 are sequentially sleeved on the skeleton 103 and connected with the skeleton 103; wherein the first shell 105 is connected with the cross-section port 1032 of the skeleton 103 through a screw. One side of the cross-section port 1032 of the skeleton 103 is provided with a groove; one end of the second shell 106 is provided with a protrusion; the protrusion of the second shell 106 is inserted into the groove to realize the cooperative connection of the second shell 106 and the cross-section port 1032 of the skeleton. Thus, the skeleton 103, the first shell 105, the second shell 106, the filter membrane 30, and the fan 102 form a fan air filter system; the fan air filter system can continuously absorb the airflow near the cleaner, the airflow including dust particles, bacteria and gas; the airflow is filtered by the filter membrane and discharged into the air; thus, the dust-free and bacteria-free effect can be realized in the cleaning process, and the technical problem that the bacteria and dust particles generated in the cleaning process fall in the air to pollute the environment in the prior art is solved, thereby realizing pollution-free cleaning.

[0024] In the preferred embodiment, the first shell 105 is a gas guide shell; the gas guide shell includes a first port and a second port; the gas guide shell is sleeved on the skeleton 103 and the first port of the gas guide shell is connected with the cross-section port 1032 of the skeleton; the second port of the gas guide shell is in the shape of a horn; the cleaner 20 passes through the second port and is connected with the skeleton 103 through the sliding shaft 1031, and the second port and the cleaner 20 have a gas guide channel for airflow input. Thus, the gas guide shell with the horn-shaped opening in the embodiment can not only increase the airflow, but also reduce the gap between the gas guide shell and the skeleton, thereby reducing the width of the gas guide channel and further increasing the airflow speed and improving the gas adsorption force on the surface of the cleaner.

[0025] In the preferred embodiment, the second shell 106 includes a frame 1061 and a steel mesh 1062 sleeved outside the frame 1061; the frame 1061 is connected with the cross-section port 1032 of the skeleton 103 relative to the first shell 105; and the filter membrane 30 is detachably installed in the steel mesh 1062.

[0026] Specifically, the frame 1061 can be a cuboid frame; one end of the cuboid frame has a protrusion; the protrusion is embedded in the groove in the skeleton 103 to realize the connection of the second shell 106 and the skeleton 103. Then the filter membrane 30 is installed in the inside of the steel mesh 1062 and fixed through a screw; finally, the steel mesh 1062 with the filter membrane 30 is sleeved on the cuboid frame to obtain the second shell with the filter membrane. The filter membrane 30 can be filter cotton, and in order to improve the bacteria removal effect of the filter membrane, the filter cotton is preferably polyester bacteria removal filter cotton, glass fiber bacteria removal filter cotton, and foam bacteria removal filter cotton.

[0027] In the preferred embodiment, the brush holder 202 is provided with a waist-shaped hole 2022; the eccentric shaft 40 comprises a second through hole and a protruding shaft arranged on the plane of the second through hole; the second output end of the motor 101 is connected with the second through hole, and the protruding shaft is inserted into the waist-shaped hole 2022; when the motor 101 rotates around its bearing, the protruding shaft moves up and down in the waist-shaped hole 2022 along a direction perpendicular to the sliding shaft 1031.

[0028] Specifically, the second output end of the motor 101 is inserted into the second through hole and fixedly connected with the second through hole; the protruding shaft is inserted into the waist-shaped hole of the brush holder 202. When the motor 101 rotates, the motor 101 drives the eccentric shaft 40 connected therewith to move up and down in the waist-shaped hole to realize the repeated movement of the cleaner 20 along the extension direction of the sliding shaft 1031. Thus, the repeated movement of the eccentric shaft in the waist-shaped hole is converted into the repeated movement of the cleaner on the sliding shaft, so that the repeated wiping of the cleaner on the surface of the container is realized, and the cleaning effect is improved.

[0029] In order to improve the adsorption force of the surface of the cleaner, in the preferred embodiment, the fan 102 is an axial fan or a centrifugal fan.

[0030] In the preferred embodiment, the length of the waist-shaped hole is greater than twice the pitch of the eccentric shaft; the swing amplitude of the brush holder on the sliding shaft 1031 is determined according to the pitch of the eccentric shaft.

[0031] Specifically, the pitch of the eccentric shaft 40 is used to indicate the distance between the protruding shaft of the eccentric shaft 40 and the center of the second through hole (or the second output end inserted into the second through hole). With the center of the second through hole as the origin, the diameter of the circle drawn by the motor 101 driving the eccentric shaft 40 to rotate one round is determined as the swing amplitude of the brush holder 202 on the sliding shaft 1031.

[0032] Thus, the negative pressure sterilization device of the embodiment converts the repeated movement of the eccentric shaft in the waist-shaped hole into the repeated swing of the brush holder on the sliding shaft, which not only effectively simulates the action of manual wiping, but also has the advantages of compact structure, small space occupation, strong power output, etc., and improves the cleaning effect of the negative pressure sterilization device.

[0033] In an embodiment not shown, an application of a negative pressure sterilization device is provided, which is applied to the end of the mechanical arm of the humanoid robot. The humanoid robot can control the negative pressure sterilization device to wipe the surface of the container, thereby solving the problems of low efficiency and high cost of manual wiping and improving the cleaning efficiency of the negative pressure sterilization device.
