Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning applications. More specifically, the present invention relates to a negative pressure sterilization device. Background Art

[0002] At present, the surface cleaning of containers for mold removal and other oily cleaning is done manually. For example, first spray the cleaning agent, then wipe and polish the surface, and finally collect the cleaning waste liquid. The manual operation process is not only time-consuming and laborious, but also for some special containers and occasions, it is not suitable to use cleaning agents for cleaning; therefore, manual wiping and polishing is not only inefficient, but also easy to 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 related fields have also tried to design automatic cleaning devices with brushes. Such cleaning devices can efficiently clean various surfaces through electric drive and the friction of brushes. In addition, the appropriate equipment and brush types can be selected according to different usage scenarios and needs, which can greatly improve the cleaning effect. However, the brushes in existing automatic cleaning devices usually wipe in one direction and cannot simulate the manual wiping and polishing action. Therefore, it is difficult to clean some stubborn stains on the surface of the container, thereby reducing the cleaning effect. Summary of the invention

[0004] In order to solve one or more of the technical problems mentioned above, the present invention provides a negative pressure sterilization device, which can not only effectively simulate the action of manual wiping, but also achieve an efficient and dust-free sterilization effect.

[0005] To achieve the above-mentioned purpose, according to the first aspect of an embodiment of the present application, a negative pressure sterilization device is provided, which includes: a power mechanism, which includes a motor, a fan, a frame, and a shell mounted on the frame; the shell includes a first shell and a second shell; the motor is arranged in the frame corresponding to the position of the first shell; the fan is arranged in the frame corresponding to the position of the second shell; the first output end of the motor is connected to the fan; a cleaner, which passes through the front end of the first shell and is connected to the frame through a sliding shaft, and is connected to the second output end of the motor through an eccentric shaft; the motor can drive the cleaner to reciprocate relative to the frame along the extension direction of the sliding shaft when the cleaner performs a cleaning task; a filter membrane, which is wrapped on the second shell with a mesh structure; the motor can drive the fan to rotate when the cleaner performs a cleaning task; the fan can provide negative pressure to the cleaner by rotating so that the airflow near the cleaner passes through the shell and is filtered by the filter membrane and then emitted into the air.

[0006] In order to achieve the above-mentioned purpose, according to the second aspect of the embodiment of the present application, an application of a negative pressure sterilization device is also provided, and the negative pressure sterilization device is applied to the end of the robotic arm of the humanoid robot.

[0007] Compared with the prior art, the embodiment of the present invention provides a negative pressure sterilization device, which includes a frame, a shell sleeved on the frame, a motor and a fan, a cleaner and a filter membrane installed in the frame in sequence. When the device is used, the first output end of the motor in the frame is connected to the fan, and the second output end of the motor is connected to the cleaner. The motor is used to provide a power source for the fan and the cleaner; the filter membrane is wrapped on the part of the shell arranged opposite to the fan. When the negative pressure sterilization device performs the cleaning task, the motor drives the cleaner to reciprocate relative to the frame along the extension direction of the sliding shaft, and the fan provides negative pressure to the cleaner driven by the motor so that the airflow near the cleaner passes through the shell and is filtered through the filter membrane and then released into the air. In this embodiment, the negative pressure sterilization device can effectively simulate the action of manual wiping by driving the cleaner to reciprocate through the motor; the negative pressure generated when the motor drives the fan to rotate sucks the airflow into the shell for filtering, so that the negative pressure sterilization device can achieve efficient and dust-free sterilization effect. It can be seen that the negative pressure sterilization device of this embodiment not only has the characteristics of compact structure and small size, but also can achieve efficient and pollution-free cleaning.

DETAILED DESCRIPTION

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

[0015] Figure 1 , which is a schematic structural diagram of a negative pressure sterilization device provided by one embodiment of the present invention; Figure 2 As shown, it is shown Figure 1 The exploded view of the negative pressure sterilization device shown in FIG. Figure 3 As shown, it is shown Figure 1 A partial diagram of the brush drive of the negative pressure sterilization device shown in FIG. Figure 4 As shown, it is shown Figure 1 The schematic diagram of the fan position of the negative pressure sterilization device shown;

[0016] like Figure 1 , Figure 2 ,as well as Figure 3As 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 shell sleeved on the frame 103; the shell includes a first shell 105 and a second shell 106; the motor 101 is arranged in the frame 103 corresponding to the position of the first shell 105; the fan 102 is arranged in the frame 103 corresponding to the position of the second shell 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 shell 105 and is connected to the frame 103 through a sliding shaft 1031, and is connected to the second output end of the motor 101 through 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 on a second shell 106 with 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 for the cleaner 20 by rotating so that the airflow near the cleaner 20 passes through the shell and is filtered by the filter membrane 30 and then emitted into the air.

[0017] When the negative pressure sterilization device is working, first, the motor 101 and the fan 102 are installed in the skeleton 103; and 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 skeleton 103 through the sliding shaft 1031; secondly, the first shell 105 is mounted on the skeleton 103 corresponding to the position of the motor 101, and the second shell 106 is mounted on the skeleton 103 corresponding to the position of the fan 102; and the first shell 105 and the second shell 106 are connected through the skeleton 103; finally, the filter membrane 30 is mounted on the second shell 106 with a mesh structure.

[0018] When the negative pressure sterilization device performs the cleaning task, the motor 101 drives the cleaner 20 to reciprocate relative to the frame 103 along the extension direction of the sliding shaft 1031 by rotating, and the fan 102, driven by the motor 101, provides negative pressure to the cleaner 20 to absorb the airflow near the cleaner 20, and the absorbed airflow passes through the first shell 105 and the second shell 106 and is filtered by the filter membrane 30 on the second shell 106 and then emitted into the air. Therefore, the negative pressure sterilization device can not only effectively simulate the manual wiping action and improve the cleaning effect of the container surface; but also the bacteria and dust particles cleaned by the cleaner can also be filtered by the filter membrane, thereby achieving an efficient and dust-free sterilization effect.

[0019] In a preferred embodiment, the cleaner 20 includes 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 that is symmetrical up and down; the front end of the skeleton 103 is provided with a sliding shaft 1031 that is symmetrical up and down; the first through hole 2021 of the brush holder 202 passes through the sliding shaft 1031 and is connected to the front end of the skeleton 103.

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

[0021] like Figure 3 A partial diagram of the brush drive is shown. The length of the sliding shaft 1031 on the frame 103 is greater than the length of the hole of the brush 201. When the motor 101 rotates, it can drive the brush holder 202 to reciprocate on the sliding shaft 1031, so that the brush on the brush holder can simulate the manual wiping action to repeatedly wipe the container surface, thereby improving the cleaning effect of the cleaner on the container surface.

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

[0023] Specifically, the first shell 105 and the second shell 106 are sequentially sleeved on the skeleton 103 and connected to the skeleton 103; wherein the first shell 105 is connected to the cross-sectional port 1032 of the skeleton 103 by screws. A groove is provided on one side of the cross-sectional port 1032 of the skeleton 103; a protrusion is provided on one end of the second shell 106; the protrusion of the second shell 106 is inserted into the groove to achieve the matching connection between the second shell 106 and the cross-sectional port 1032 of the skeleton 103. Thus, the skeleton 103, the first shell 105, the second shell 106, the filter membrane 30, and the fan 102 constitute the fan 102 air filter system; the fan 102 air filter system can continuously absorb the airflow near the cleaner 20, which includes dust particles, bacteria and gas; the airflow is filtered by the filter membrane 30 and discharged into the air; thus, the effect of dust-free sterilization can be achieved in the cleaning process, which solves the technical problem of bacteria and dust particles generated in the cleaning process floating in the air and polluting the air in the prior art, and achieves pollution-free cleaning.

[0024] In a preferred embodiment, the first housing 105 is an air-guiding housing; the air-guiding housing includes a first port and a second port; the air-guiding housing is sleeved on the frame 103 and the first port of the air-guiding housing is connected to the cross-sectional port 1032 of the frame 103; the second port of the air-guiding housing is trumpet-shaped; the cleaner 20 passes through the second port and is connected to the frame 103 via a sliding shaft 1031, and an air-guiding channel for airflow input is provided between the second port and the cleaner 20. Therefore, the air-guiding housing with a trumpet-shaped opening in this embodiment can not only increase the airflow, but also reduce the gap between the air-guiding housing and the frame, thereby reducing the width of the air-guiding channel, thereby increasing the airflow velocity, and improving the gas adsorption force on the surface of the cleaner.

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

[0026] Specifically, the frame 1061 can be a rectangular parallelepiped frame 1061; one end of the rectangular parallelepiped frame 1061 has a protrusion; the protrusion is embedded in the groove in the frame 103 to achieve the connection between the second housing 106 and the frame 103. Then, the filter membrane 30 is installed inside the steel mesh 1062 and fixed by screws; finally, the steel mesh 1062 with the filter membrane 30 is sleeved on the rectangular parallelepiped frame 1061 to obtain the second housing 106 with the filter membrane 30. The filter membrane 30 can be a filter cotton, in order to improve the sterilization effect of the filter membrane; preferably, the filter cotton is a polyester sterilization filter cotton, a glass fiber sterilization filter cotton, and a foam sterilization filter cotton.

[0027] In a preferred embodiment, the brush holder 202 is provided with a straight waist hole 2022; the eccentric shaft 40 includes a second through hole 401, and a protruding shaft arranged on the plane where the second through hole 401 is located; the second output end of the motor 101 is cooperatively connected with the second through hole 401, and the protruding shaft is inserted into the straight waist hole 2022; when the motor 101 makes a circular motion around its bearing, it drives the protruding shaft to make up and down reciprocating motion in the straight waist hole 2022 along a direction perpendicular to the sliding shaft 1031.

[0028] Specifically, the second output end of the motor 101 is passed through the second through hole 401 and fixedly connected to the second through hole 401; the protruding shaft is inserted into the straight hole of the brush holder 202. When the motor 101 rotates, the motor 101 drives the eccentric shaft 40 connected thereto to make up and down reciprocating motions in the straight hole to achieve the repeated motion of the cleaner 20 along the extension direction of the sliding shaft 1031. Thus, the reciprocating motion of the eccentric shaft in the straight hole is converted into the reciprocating motion of the cleaner on the sliding shaft, thereby achieving the repeated wiping of the container surface by the cleaner and improving the cleaning effect.

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

[0030] In a preferred embodiment, the length of the straight waist hole 2022 is greater than twice the wheelbase of the eccentric shaft 40 ; the swing amplitude of the brush holder 202 on the sliding shaft 1031 of the skeleton 103 is determined according to the wheelbase of the eccentric shaft 40 .

[0031] Specifically, the wheelbase of the eccentric shaft 40 is used to indicate the distance between the protruding shaft on the eccentric shaft 40 and the center of the second through hole 401 (or the second output end inserted into the second through hole 401). With the center of the second through hole 401 as the origin, the diameter of the circle obtained by the motor 101 driving the eccentric shaft 40 to rotate one circle is determined as the swing amplitude of the brush holder 202 on the sliding shaft 1031.

[0032] Therefore, the negative pressure sterilization device of this embodiment combines the reciprocating motion of the straight waist hole in the eccentric shaft and the reciprocating swinging of the brush holder on the sliding shaft, which can not only effectively simulate the manual wiping action, but also the overall structure has the advantages of compact design, small space occupation, strong power output, etc., thereby improving 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, and the negative pressure sterilization device 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 problem of low efficiency and high cost of manual wiping, and improving the cleaning efficiency and cleaning effect.
