Technical Field
The invention relates to the field of medical appliances, in particular to an energy-saving humidifying water box.
Background
Before the air of the breathing machine enters the human respiratory system, a humidifying device is generally adopted to humidify the air of the breathing machine. The hot steam is generated in the humidifying water box by heating water, and the air of the breathing machine is humidified by the hot steam. The area of the heating plate in the humidifying water box only occupies a small part of the area of the bottom of the humidifying water box, and when the heating plate heats, some energy can be wasted and the starting time is long.
The patent document with the authority of CN204319472U discloses a water box device in a household breathing machine, which comprises a water box for containing water and a heat conductor, and is characterized by also comprising a dewatering plate, wherein the dewatering plate is a plate in a closed loop shape and is arranged in an inner cavity of the water box, and the water in the water box is divided into an inner part and an outer part which are accommodated in the dewatering plate to form a corresponding dewatering area and a water box area; the heat conductor is arranged at the bottom of the water box corresponding to the precipitation area, and at least one notch for communicating the water box area with the precipitation area is arranged on the lower side of the precipitation plate.
The proposal of the patent document has more processing steps, more complex structure and increased cost, and the notch is positioned at the bottom and is easy to be blocked; the notch is positioned at the bottom of the precipitation plate, and heat of water is more convenient to transfer from bottom to top, so that when the heat conductor heats the water in the precipitation area, the water in the vicinity of the notch in the water box area is still transferred, and the water is positioned at the bottom of the water box area, so that heat transfer is faster, and therefore, some waste exists for the heat.
Disclosure of Invention
The invention mainly aims to provide an energy-saving humidifying water box which is convenient to process, difficult to block, short in starting time of a breathing machine and high in energy utilization rate.
In order to achieve the above purpose, the invention provides an energy-saving humidifying water box, which comprises a closed box body, wherein the upper part of the box body is provided with an air inlet and an air outlet; the box body is internally provided with a heating tank, the side wall of the heating tank is provided with a strip-shaped groove, the inside and the outside of the heating tank are communicated through the strip-shaped groove, and the bottom of the heating tank is provided with a heating component.
Further improved, the air inlet and the air outlet are arranged on the top surface of the box body, and the air inlet and the air outlet are positioned above the heating pool. Theoretically, the air inlet and the air outlet are arranged at the upper part of the side face of the box body, and the like, but because the hot steam moves upwards, the air inlet and the air outlet are arranged above the heating pool, so that the hot steam meets the air more conveniently, and the utilization rate of the hot steam can be improved.
Further improved, the top surface in the box body is equipped with first barricade and second barricade, air inlet and gas outlet are located between first barricade and the second barricade, first barricade and second barricade extend towards the heating pool direction respectively. Through first barricade and second barricade, can guide the hot steam that the heating pond produced and the air of air inlet meet, improve the utilization ratio of hot steam.
Further improved, the first retaining wall and the second retaining wall are vertically arranged.
Further improved, the first retaining wall and the second retaining wall are connected to form a closed enclosing wall, the air inlet and the air outlet are located in the enclosing wall, the enclosing wall extends towards the heating pool to be in butt joint, and the enclosing wall is sleeved outside the heating pool. The first retaining wall and the second retaining wall are connected with the structure of the urban surrounding wall, so that the hot steam generated by the heating pool is more conveniently guided.
Further improved, the bottom end of the air outlet is provided with a horn connecting pipe, one end with a larger diameter of the horn connecting pipe is arranged downwards, the bottom end of the horn connecting pipe extends to the upper part of the heating pool, and a gap is reserved between the horn connecting pipe and the bottom end and between the horn connecting pipe and the heating pool. The air entering through the air inlet can be led to enter the horn connecting pipe through the gap, and meets with the hot steam in the horn connecting pipe, and finally flows out of the air outlet, so that the hot steam can be prevented from flowing into the area outside the horn connecting pipe, and the utilization rate of the hot steam is improved.
Further improved, the length direction of the strip-shaped groove is arranged in a vertical mode along the side wall of the heating pool. The strip groove of vertical setting can play the effect of the inside and outside region of intercommunication heating bath, but the position of strip groove intercommunication is evenly distributed on the lateral wall of heating bath, and when heating element heated the water in the heating bath, convection current between the water of the outer bottom of the water box heating bath of heating bath bottom would reduce a lot, also can reduce the waste of some energy to a certain extent.
Further improved, the width of the strip-shaped groove is 0.5 mm-2 mm. Preferably, the width of the strip-shaped groove is 1mm, so that a certain temperature difference can be ensured inside and outside the heating pool, and convection can be realized inside and outside the heating pool, so that a liquid level difference cannot exist inside and outside the heating pool.
Further improved, the heating assembly comprises a heating plate, the heating plate is paved at the bottom of the heating tank, and the area of the heating plate is equal to the area of the bottom surface of the heating tank. The heat utilization rate on the heating plate can be improved. The heating assembly also includes a heat source, which may be a resistance wire or other heating means, by which the heating plate is heated.
Further improved, the air inlet is connected with an air inlet pipe, and the air outlet is connected with an air outlet pipe. The air inlet pipe/air outlet pipe is convenient for the air inlet/air outlet to be connected with other parts of the breathing machine.
