Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ventilation pipes, and specifically relates to a dust-proof ventilation pipe. Background Art
[0002] A ventilation pipe is a hollow pipe used for ventilation, mostly circular or square. The plates, profiles and other main finished materials used in the manufacture and installation of ventilation pipes generally include circular, rectangular, spiral, corrugated, etc. The main function of the ventilation pipe is to provide a mechanism for indoor and outdoor air to circulate, which is crucial for controlling the temperature, humidity and air quality of the indoor environment. Good ventilation can dilute and remove indoor pollutants.
[0003] A Chinese patent with the publication number CN207112207U discloses a ventilation pipe, which includes an inner pipe and an outer pipe. The outer pipe is sleeved on the outer side wall of the inner pipe, and the inlet end of the outer pipe is connected to the outer side wall of one end of the inner pipe, and the outlet end of the outer pipe is connected to the outer side wall of the other end of the inner pipe; a first coolant channel is formed between the inner side wall of the outer pipe and the outer side wall of the inner pipe; a coolant inlet is provided at the inlet end of the outer pipe, and the coolant inlet is communicated with the first coolant channel; a coolant outlet is provided at the outlet end of the outer pipe, and the coolant outlet is communicated with the first coolant channel, so that it can effectively prevent the air leakage in the ventilation pipe from freezing under low temperature conditions and the cost of the ventilation pipe is relatively low.
[0004] In the above application, components such as an inner pipe, an outer pipe and a coolant channel are used to form a ventilation pipe and achieve the function of preventing freezing. Among them, the component structure of the ventilation pipe does not involve a filtering structure or a detachable function, and it is easy to enter dust and sundries during use, which affects the internal blockage of the ventilation pipe and further affects the normal use of the ventilation pipe. In addition, the ventilation pipe is prone to offset at the interface, so a reinforcement component needs to be set to enhance the fixing effect. Therefore, the ventilation pipe has deficiencies in terms of dust prevention and preventing offset problems. Summary of the Utility Model
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model provides a dust-proof ventilation pipe, which includes a main body. The main body includes a ventilation pipe device, a filter screen structure and a reinforcement component. A ventilation duct is provided outside the ventilation pipe device, and a connection axis is provided outside the ventilation duct; a connection clamping ring is provided outside the filter screen structure, a filter plate is provided inside the connection clamping ring, a connection ring is connected to the bottom of the connection clamping ring, and a filter mesh cover is provided inside the connection ring; fasteners are provided on both sides outside the reinforcement component, a connection block body is provided on one side of the fastener, a screw cavity is provided on the top of the connection block body, and a fastening rivet and a cap are installed on the top of the screw cavity.
[0007] A filter screen structure is set up to prevent dust and sundries from entering the inside of the ventilation duct and affecting its normal use. By setting a double-layer filtering structure at the air inlet and outlet of the ventilation duct, an outer filter screen cover is set. The strip plates in the filter screen cover prevent sundries from entering the ventilation duct, achieving the blocking of sundries with larger volumes. At the same time, a filter plate is set at the bottom of the filter screen cover. A number of through holes on the surface of the filter plate allow dust and small-volume dirt to enter the inside of the ventilation duct, and the through holes do not affect the ventilation effect. The double-layer filtering of the pipe orifice realizes the dust-proof effect of the ventilation duct, thereby improving the working efficiency of the ventilation duct.
[0008] In addition, a reinforcement component is set. The two sides of the fastener cooperate with the fastening rivets to be fixed to the bottom of the internal screw cavity, realizing the fixation of the two ends of the ventilation duct by the fasteners, thus strengthening the fixation effect at both ends of the ventilation duct, and further avoiding the ventilation duct from being loosely fixed and shifted during use, which affects the working efficiency of the ventilation duct.
[0009] Furthermore, the ventilation duct is tubular and has elbows inside. There are two groups of elbows located at the bending parts of the air inlet pipe and the air outlet pipe. The outside of the elbows is provided with a connecting axis connected to the inside of the ventilation duct. Both the air inlet pipe and the air outlet pipe are provided with exhaust hoods inside. The exhaust hoods are cylindrical and internally reticulated.
[0010] Furthermore, the connecting collar is cylindrical and is adaptively connected to the bottom of the ventilation duct. The filter plate is a circular plate with a number of through holes opened inside. The through holes are all circular and penetrate both sides of the filter plate, and are equidistantly distributed in a circumferential array. The coupling ring is annular and is the same size as and adaptively connected to the connecting collar. The filter screen cover is composed of a number of strip plates arranged in combination. The two ends of the strip plates are tangentially connected to the coupling ring and are equidistantly distributed in a straight line.
[0011] Furthermore, there are two groups of fasteners, both of which are arc-shaped blocks and are symmetrically distributed in a straight line. The connecting block is a square block located at the center position outside the fastener. The screw cavity is a circular chamber. The screw cavity is located in the middle of the connecting block. A fixing opening is opened inside the screw cavity. The fixing opening is circular and extends to the bottom of the screw cavity.
[0012] Furthermore, there are two groups of fastening rivets, both of which are cylindrical and are centrally symmetrically distributed. The top of the fastening rivet is provided with a cap. The cap is hexagonal prism-shaped and is adaptively connected to the center position of the fastening rivet.
[0013] The utility model has the following beneficial effects:
[0014] The present utility model: A filter screen structure is provided to prevent dust and sundries from entering the interior of the ventilation duct, which may affect the normal use of the ventilation duct. By setting a double-layer filtering structure at the air inlet and outlet of the ventilation duct, a filter screen cover is arranged on the outer layer. The strip-shaped plate in the filter screen cover prevents sundries from entering the ventilation duct, achieving the blocking of larger-sized sundries. At the same time, a filter plate is arranged at the bottom of the filter screen cover. The several through holes on the surface of the filter plate enable dust and small-sized dirt to enter the interior of the ventilation duct, and the through holes do not affect the ventilation effect. The dust-proof effect of the ventilation duct is achieved through the double-layer filtering of the pipe orifice, thereby improving the working efficiency of the ventilation duct.
[0015] (2)The present utility model: A reinforcement component is provided. By means of the fasteners on both sides cooperating with the fastening rivets to be fixed to the bottom of the internal screw cavity, the fasteners fix the two ends of the ventilation duct interface, thus strengthening the fixing effect at both ends of the ventilation duct, and further preventing the ventilation duct from shifting due to loose fixing during use, which may affect the working efficiency of the ventilation duct.
