[0007] As an improvement of the utility model, the air guide piece is arc-shaped and one section is arranged opposite to the vent.

[0008] As an improvement of the utility model, the ventilation cross-section of the air duct gradually decreases starting from the air inlet.

[0009] As an improvement of the utility model, the air guide blades are arranged at intervals along the air duct.

[0010] As an improvement of the utility model, the air duct is arc-shaped, and the air inlet is composed of a sealing sheet and an inner wall of the air duct.

[0011] After adopting the above structure, the constant pressure air duct milk warmer of the utility model has the following advantages compared with the prior art: by setting the air duct, the hot air component can be reasonably guided to blow out hot air, and a sealing sheet is set at the tail of the air duct to avoid the air duct from forming a circulating air duct and avoiding the accumulation of hot air, and the pressure in the air duct can be quickly increased, and the hot air can be quickly guided to the bottle area, and several air guide sheets in the air duct can distribute the hot air flow rate and flow in the air duct, so that the hot air is more uniform in the air duct and the hot air is blown into the bottle area more uniformly.

[0014] As shown in the figure: 100, milk bottle basket; 110, vent; 200, hot air component; 300, air duct; 310, air inlet; 320, sealing sheet; 330, air guide sheet; 400, shell. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] See also Figure 1-Figure 2 The constant pressure air duct milk warmer shown includes a bottle basket 100 and a hot air component 200, and also includes an air duct 300. The air duct 300 is provided with an air inlet 310 connected to the hot air component 200, and the other end of the air duct 300 is sealed with a sealing sheet 320. A plurality of air guide plates 330 are provided in the air duct 300. By providing the air duct 300, the hot air blown out by the hot air component 200 can be reasonably guided, and the sealing sheet 320 is provided at the tail end of the air duct 300 to avoid the air duct 300 from forming a circulating air duct 300, avoid hot air accumulation, and can quickly increase the pressure in the air duct 300, can quickly guide the hot air to the bottle area, and the plurality of air guide plates 330 in the air duct 300 can distribute the hot air flow rate and flow in the air duct 300, so that the hot air is more uniform in the air duct 300, and the hot air is blown into the bottle area more uniformly.

[0017] See also Figure 1-Figure 2The constant pressure air duct milk warmer shown also includes a shell 400, the outer wall of the milk bottle basket 100 cooperates with the shell 400 to form an air duct 300, and the outer wall of the milk bottle basket 100 is provided with a plurality of vents 110 connected with the air duct 300 along the circumferential direction, which can evenly introduce the hot air in the air duct 300 into the milk bottle basket 100, so that the hot air is blown into the milk bottle area more evenly. The air guide 330 is arc-shaped and is arranged opposite to the vent 110 at one section, that is, it cuts the hot air in the air duct 300 to a certain extent, and balances the flow velocity and pressure difference caused by the distance of the air duct 300. The ventilation cross section of the air duct 300 gradually decreases from the air inlet 310, and cooperates with the air duct 300 with a gradually decreasing cross-sectional area, so that when the air flow in the air duct 300 does not circulate, the hot air in the air duct 300 is more even, and the hot air in the air duct 300 can be evenly introduced into the milk bottle basket 100.

[0018] See also Figure 1-Figure 2 In the constant pressure air duct milk warmer shown, the air guide plates 330 are arranged at intervals along the air duct 300, which has a better air guiding effect and less wind velocity loss. The air duct 300 is arc-shaped, which has a better guiding effect and reduces noise. The air inlet 310 is composed of a sealing plate 320 and the inner wall of the air duct 300, that is, one end face of the sealing plate 320 has a sealing function and the other end face is a guiding surface of the air inlet 310, which makes the structure more compact and reasonable and reduces the number of components.
