Abstract

The utility model discloses a house ventilation device, which comprises a ventilation pipeline, wherein a sleeve is sleeved at one end of the ventilation pipeline, a limiting column is fixedly connected with the sleeve, a wax motor is fixedly arranged in the limiting column, an opening is formed in the bottom of the limiting column, one end of the wax motor extends out of the opening of the limiting column, an internal thread is arranged at the opening at the upper end of the limiting column, the upper end of the limiting column is integrally sleeved with a connecting column, and a top cover is fixedly connected to the top of the connecting column. The utility model relates to a house ventilation equipment, which adopts a wax motor taking a paraffin core as a main material as an equipment core, and because the thermal expansion coefficient of paraffin is smaller, when the paraffin is cold, a top cover is tightly covered on a sleeve to form a seal, so that no air flows in a room, the warmth of the room is ensured, when the temperature is higher, the paraffin is heated and expanded, a top rod jack jacks up the whole top cover upwards, and a gap is formed between the top cover and the sleeve at the moment, so that ventilation is started indoors and outdoors, and the whole process does not need to be electric and is changed automatically according to the temperature change.

Description

House ventilation equipment Technical Field The utility model relates to the technical field of house ventilation equipment, in particular to house ventilation equipment. Background The ventilation pipe is hollow pipe material for ventilation, and is round or square. The plates, the profiles and other main finished materials used for manufacturing and installing the ventilation pipe are in accordance with the regulations of the national current standards of design and related products, and the factory inspection is applied to qualify and prove that the materials are inspected according to the national current related standards when entering the field, along with the economic development, the urban process is quickened, people gather together for life work, and in order to enable air to circulate better, the breathing air quality of the people is guaranteed, so the ventilation pipe is widely applied to various places of people life and work, and the functional requirements on the ventilation pipe are also higher and higher. The house walls in some cold areas are thick, so that the ventilation equipment is inconvenient to construct and install, corresponding pipeline positions are needed to be cut out in the initial stage of building, and a plurality of problems such as circuit wire connection at a planning position are needed to be arranged, meanwhile, the influence on equipment in cold weather is prevented, and the method is inconvenient. In order to solve the problems, the proposal is generated. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a house ventilation device, which solves the problems in the background art. The house ventilation equipment comprises a ventilation pipeline, wherein a sleeve is sleeved at one end of the ventilation pipeline, a second limiting column is fixedly connected with the sleeve, a wax motor is fixedly arranged in the second limiting column, an opening is formed in the bottom of the second limiting column, one end of the wax motor extends out of the opening of the second limiting column, an internal thread is formed in the opening of the upper end of the second limiting column, the upper end of the second limiting column is integrally sleeved with a connecting column, and a top cover is fixedly connected to the top of the connecting column. Preferably, the bottom surface of the top cover is conical and folded downwards, foam cotton materials are integrally arranged on the bottom surface of the top cover, and a plurality of holes are formed in the bottom surface of the sleeve in the circumferential direction. Preferably, the hole is fixedly connected with a plurality of spacing posts, the spacing posts are staggered, and the non-woven fabric filter bag is fixedly sleeved on the spacing posts. Preferably, a push rod is arranged in the wax motor, the top of the push rod penetrates out of the wax motor, and the push rod is positioned in the middle of the connecting column. Preferably, a paraffin core is arranged below the ejector rod, and the paraffin core is in a shape with a small upper part and a large lower part.
