Description

Technical Field

[0001] The utility model relates to the technical field of sealing devices, and more specifically, to a liquid sealing structure and a portable toilet. Background Art

[0002] The sealing structure is divided into static seals between relatively stationary parts and dynamic seals between relatively moving parts according to the working state of the sealing parts. Dynamic seals are divided into reciprocating and rotary seals according to the different forms of movement. The main sealing method is to place a sealing gasket at the connection between two parts. The gasket material is mostly elastic, such as rubber, plastic, asbestos, etc. Pressure is applied to the sealing gasket to deform it to fill the gap at the connection of the parts, thereby achieving a sealing effect. The reciprocating dynamic seals currently on the market are manual or pneumatic, and occupy a large volume.

[0003] The common reciprocating dynamic seal structures on the market are mostly directly driven. The driving components, sealing valves, plus the stroke required to open and close the valves, the entire structure occupies a large space, which is not conducive to the sealing of small portable toilet parts.

Guide rails are provided on both sides of the gate port, the sealing plate is rotatably connected to the mounting block through a connecting rod, and the mounting block is driven to slide on the guide rail by the driver, thereby driving the sealing plate to move towards or away from the gate port, and the gate port can be closed and opened. The sealing plate closes and opens the gate port by translation, thereby reducing the space required for the opening and closing of the automatic isolation gate for the vacuum box, and facilitating automatic loading and unloading equipment to load and unload materials into the vacuum box. When the technical solution adopts the method of the driver directly driving the sealing plate to move, the required installation space is large. Utility Model Content

[0007] In the present technical solution, the sealing baffle is driven by the driving assembly to slide horizontally along the connecting port on the shell to achieve the isolation and connection of the connecting port.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0029] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0030] Embodiment 1:

[0031] As shown in the figure, a liquid sealing structure is provided, including a shell 1, a sealing baffle 2, a driving assembly and a detection assembly, the shell 1 is penetrated by a communication port 101, the sealing baffle 2 is slidably connected to the communication port 101, the driving assembly is installed on the shell 1, the driving assembly is connected to the sealing baffle for driving the sealing baffle 2 to slide to close or open the communication port 101, and the detection assembly is installed on the sliding path of the sealing baffle 2 for detecting the position of the sealing baffle 2 and is electrically connected to the driving assembly.

[0032] Specifically, the driving assembly includes a telescopic structure 7, a push rod 6 and a connecting plate 5. The telescopic structure 7 and the push rod 6 are arranged side by side, and the telescopic end of the telescopic structure 7 and one end of the push rod 6 are respectively connected to the connecting plate 5, and the other end of the push rod 6 is connected to the sealing baffle 2.

[0033] In this embodiment, the telescopic structure 7 is a telescopic cylinder, and the telescopic ends of the push rod 6 and the telescopic structure 7 are respectively fixed to the connecting plate 5 by bolts. The connecting plate 5 is used to transmit the driving force of the telescopic structure 7 to avoid direct drive, occupy a small space, and have a compact structure.

[0034] Specifically, the telescopic end of the telescopic structure 7 and one end of the push rod 6 are respectively vertically fixed on one side of the connecting plate 5. In this embodiment, when the telescopic end of the telescopic structure 7 is extended, the push rod 6 is driven to extend out of the shell 1 to pull out the sealing baffle 6, thereby opening the connecting port 101. When the telescopic end of the telescopic structure 7 is retracted, the push rod 6 is driven to be pushed downward into the shell 1 to push the sealing baffle 6 into the connecting port 101, thereby closing the connecting port 101.

[0035] Specifically, the detection component includes a first photoelectric sensor 3 and a second photoelectric sensor 4 which are electrically connected to the driving component respectively. The first photoelectric sensor 3 and the second photoelectric sensor 4 are respectively arranged at a first position and a second position of the driving component along its movement direction. When the telescopic end of the telescopic structure 7 is fully extended, the end surface of the connecting plate 5 connected to the telescopic end can just block the second photoelectric sensor 4, so that the second photoelectric sensor 4 can send a signal that the connecting port 101 is in an open state. When the telescopic end of the telescopic structure 7 is fully retracted, the end surface of the connecting plate 5 connected to the telescopic end can just not block the first photoelectric sensor 3, so that the first photoelectric sensor 3 sends a signal that the connecting port is closed.

[0036] In this embodiment, the photoelectric sensor can be divided into a slot-type photoelectric sensor, a beam-type photoelectric sensor, a reflector-type photoelectric sensor, and a diffuse reflection-type photoelectric sensor, and the first photoelectric sensor 3 and the second photoelectric sensor 4 can be diffuse reflection-type photoelectric sensors, which are based on the photoelectric effect and involve the process of converting non-electrical signals into electrical signals. When light is irradiated onto the surface of the driving component, it causes electrons to jump from the surface of the material to the vacuum or the inside of the semiconductor, thereby generating a current or potential difference. The first photoelectric sensor 3 and the second photoelectric sensor 4 use photodiodes to detect light signals. The photodiode is composed of a PN structure. When the photodiode is illuminated, photons excite electrons in the P-type and N-type regions, causing the electrons in the semiconductor to generate photogenerated carriers through energy band transitions. Then, due to the special structure of the PN junction, electrons will move to the N-type region, and holes will move to the P-type region. The moving electrons and holes are collected at the PN junction boundary and form a photocurrent to the outside world. In addition, the first photoelectric sensor 3 and the second photoelectric sensor 4 both include three parts: a light source, an optical path, and a photoelectric element. The light source emits a light beam, which passes through the optical system and hits the object to be measured. The light beam reflected by the object passes through the optical system and hits the photoelectric device again. The photoelectric device converts the light signal into an electrical signal, which is finally processed by the signal processing circuit and output, thus realizing position feedback and precise driving of the drive component.

[0037] Specifically, the first photoelectric sensor 3 is arranged at the retracted position of the telescopic structure 7, the second photoelectric sensor 4 is arranged at the extended position of the telescopic structure 7, and the end face of the connecting plate 5 is provided with a shading plate. In this embodiment, the width of the connecting port is equal to the telescopic length of the telescopic structure 7.

[0039] In this embodiment, the shell 1 includes an upper shell 102 and a lower shell 103, and the upper shell 102 and the lower shell 103 are connected by screws. A third sealing structure 12 is pressed between the upper shell 102 and the lower shell 103. The third sealing structure 12 is a foam strip, which effectively prevents water seepage between the upper shell 102 and the lower shell 103.

[0040] Specifically, a sliding hole communicating with the interlayer is provided at one end of the housing 1 , the push rod 6 extends into the interlayer through the sliding hole, and a first sealing structure 8 is provided between the sliding hole and the push rod 6 .

[0041] In this embodiment, the first sealing structure 8 is pressed against one end of the housing 1 by a first pressing plate 9 .

[0042] Specifically, a second sealing structure 10 is provided between the interlayers at the position of the communication port 101 .

[0043] In this embodiment, the second sealing structure 10 is pressed by the second pressing plate 11 , so that the second sealing structure 10 can press the end surface of the sealing baffle 2 to achieve sealing of the communication port 101 .
