Embodiments of the invention

In the following description, a lot of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" The orientation or positional relationship of other indications is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation and The azimuth structure and operation of, therefore cannot be understood as a limitation of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.

As shown in Figures 1 to 4, a heating one-way distributor includes: a housing 1, a feed port 2, a feed channel 3, a stroke guide sleeve 3, a sealing ball seat 4, a sealing steel ball 5, and a discharge Channel 6, discharge port 7.

Wherein, two feed ports 2 are provided on the upper surface of the housing 1, and one feed port 2 is provided on two opposite sides thereof, as shown in FIG. 3, the four feed ports 2 Are communicated with each other through a feed channel 3 provided inside the housing 1, and the four feed ports 2 and the feed channel 3 are all located on the same cross-section (AA); a stroke guide is provided in the feed channel 3 Sleeve 3, a sealing ball seat 4 is sleeved on the stroke guide sleeve 3, a sealing steel ball 5 installed in the sealing ball seat 4, the sealing steel ball 5 can roll back and forth along the sealing ball seat 4; the discharge channel 6 is located in the sealing channel In the middle position and along the normal direction through the sealed channel, two feed ports 2 are provided on the upper surface of the housing 1, and one feed port 2 is provided on two opposite sides, as shown in Figure 4 The four discharge ports 7 are communicated with each other through a discharge channel 6 arranged inside the casing 1, and the four feed ports 2 and the feed channel 3 are all located on the same cross-section (BB).
