By adopting the technical scheme, through the cooperation of the first half groove and the second half groove, the air outlet can be communicated with the air outlet flow channel, and the balance pipe is built-in, so that the layout is more reasonable, the ageing and damage of the balance pipe are avoided, the safety coefficient is higher, and the stability is better.
Still further, the present utility model provides: the second shell is provided with an air inlet, the air inlet groove is arranged on the air inlet, the second shell is provided with an air outlet matched with the air inlet, and the second shell further comprises an air vent groove penetrating through the inner walls of the air inlet and the air outlet.
By adopting the technical scheme, when in use, the valve plate is arranged between the air inlet and the air outlet, or the valve plate is arranged on the air outlet, then the valve plate is opened for ventilation, and when the valve plate is just opened, the valve plate can be ventilated through the ventilation groove, at the moment, the unit area of the ventilation groove is smaller, the pressure intensity is high, the reaction speed is higher, and the reaction effect can be improved.
Still further, the present utility model provides: the ventilation grooves are arranged at intervals along the circumferential direction.
By adopting the technical scheme, when the valve plate is completely opened, the ventilation groove can increase the flow area, so that the flow rate is increased, and the effect is better when the valve plate is used.
The utility model is further provided with: a seal is disposed between the first housing and the second housing.
By adopting the technical scheme, the air leakage between the first shell and the second shell can be prevented, so that the effect is better and the stability is higher when the air leakage type air conditioner is used.
The utility model is further provided with: the sealing piece comprises a sealing groove and a sealing ring, wherein the sealing groove is arranged on the first shell and distributed along the outer edges of the first half groove and the air outlet, and the sealing ring is arranged on the sealing groove.
By adopting the technical scheme, when in use, the first shell is connected with the second shell, and then the sealing ring is pressed on the sealing groove through the second shell to achieve the sealing effect, and the air leakage at a single position can be fully prevented along the distribution of the outer edges of the first half groove and the air outlet, so that the sealing effect is further improved.

Description of the embodiments
The following detailed description of specific embodiments of the utility model refers to the accompanying drawings:
in the description of the present utility model, it should be understood that the terms "upper," "lower," "bottom," "top," "front," "rear," "inner," "outer," "left," "right," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be configured and operated in a particular orientation, and thus should not be construed as limiting the present utility model.
The utility model discloses a carburetor with a built-in balance pipe, which comprises a first shell 1 and a second shell 2 which are arranged in a split mode, wherein an air inlet groove 3 (the most preferable waist-shaped groove is adopted for the air inlet groove 3) is arranged on the second shell 2, and air outlet holes 4 are formed at two ends of the air inlet groove 3.
Be equipped with air inlet 9 on the second casing 2, air inlet 3 locates on the air inlet 9, be equipped with on the second casing 2 with the gas outlet 10 of air inlet 9 looks adaptation, still including running through the ventilation groove 11 that sets up on air inlet 9 and gas outlet 10 inner wall, during the use, can set up the valve plate usually between air inlet 9 and gas outlet 10, or set up the valve plate on gas outlet 10, then open through the valve plate and ventilate, of course when the valve plate just opens, can ventilate through ventilation groove 11, at this moment, the unit area ratio of ventilation groove 11 is less, and the great reaction rate of pressure is faster, can improve the reaction effect.
