Description

Technical Field

[0001] This utility model relates to the field of atomization device technology, specifically to an atomizing spray gun for preparing aerogel particles. Background Technology

[0002] The patent with authorization announcement number CN104384037B discloses an atomizing nozzle, which includes a nozzle, an atomizing cavity, a fluid connector, a swirl vane, etc. The fluid connector needs to be connected to the gas flow channel at the atomizing cavity. However, the fluid connector and the nozzle are connected by a thread. When the fluid connector rotates to complete the docking with the nozzle, it needs to simultaneously complete the connection with the gas flow channel of the atomizing cavity. The required precision of the connection is too high and needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses an atomizing spray gun for preparing aerogel particles, comprising a fluid connector, a swirl vane, a nozzle, and an atomizing chamber. The nozzle has an opening at its tail end communicating with its internal cavity, and a spray hole at its head end communicating with its internal cavity. The atomizing chamber and the fluid connector are arranged sequentially along the axial direction in the cavity. The atomizing chamber has a gas channel and a liquid channel, and the fluid connector has a gas channel and a liquid channel. The gas channel and the liquid channel are correspondingly connected. The swirl vane is arranged on the end face of the atomizing chamber facing the fluid and corresponds to the liquid channel. A positioning block is radially protruding from the peripheral wall of the tail end of the atomizing chamber, and multiple positioning blocks are spaced apart circumferentially. The positioning block is inserted into a slot corresponding to the end face of the fluid connector. A rotating cylinder is fitted on the peripheral wall of the fluid connector, and the two are rotatably engaged. The peripheral surface of the rotating cylinder is threadedly connected to the cavity wall of the corresponding nozzle.

[0005] During installation, if the atomizing chamber and the fluid connector are fixed together as one unit in advance by the positioning block, the fluid connector is connected to the corresponding gas flow channel and liquid flow channel of the atomizing chamber under the positioning block. In this solution, the fluid connector does not need to be rotated, only the rotating drum needs to be rotated to form a connection with the nozzle, which is convenient for docking and reduces the difficulty of docking.

[0006] Furthermore, a groove is provided on the first end face of the fluid connector, and the tail end of the atomizing cavity is inserted into the groove. A slot is provided at the groove opening end face of the groove to cooperate with the positioning block, thereby improving stability.

[0007] Furthermore, the fluid connector has a threaded end cap connected to its circumferential surface near the tail end. The circumferential wall of the fluid connector is stepped along the axial direction. The rotating cylinder is rotatably connected in the space between the end cap and the corresponding stepped interface. When in use, if the rotating cylinder is put on the fluid connector and then the end cap is screwed on at the tail end, the rotating cylinder is effectively limited, which facilitates installation and shaping.

[0008] Furthermore, the first gas flow channel is distributed around the first liquid flow channel, and the second gas flow channel is distributed around the second liquid flow channel.

[0009] Furthermore, an atomizing chamber is provided at the first end of the atomizing cavity, and both the liquid flow channel one and the gas flow channel one are connected to the atomizing chamber.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model improves the docking structure between the atomizing chamber and the fluid connector, as well as the docking structure between the fluid connector and the nozzle, which facilitates the alignment and connection of the flow channels and reduces the difficulty of docking.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1 , Figure 2As shown, in this example, an atomizing spray gun for preparing aerogel particles includes a fluid connector 3, a swirl vane 4, a nozzle 1, and an atomizing chamber 2. The tail end of the nozzle 1 is formed with an opening communicating with its internal cavity 100, and the head end of the nozzle 1 is formed with a spray hole 101 communicating with its internal cavity. The atomizing chamber 2 and the fluid connector 3 are sequentially installed in its cavity 100 along the axial direction, and the tail end of the fluid connector 3 extends out from the opening.

[0020] In this example, gas flow channel 21 and liquid flow channel 22 are formed along the axial direction inside the atomizing cavity 2. The gas flow channel 21 is evenly distributed around the liquid flow channel 22. An atomizing cavity 23 connected to the liquid flow channel 22 is formed in the first end of the atomizing cavity 2. The diameter of the first end of the atomizing cavity 2 is smaller than the diameter of the tail end. An annular air channel 24 is formed between the circumferential surface of the first end of the atomizing cavity 2 and the corresponding cavity wall 100. A channel is formed radially in the cavity wall of the atomizing cavity 23 to connect with the annular air channel 24. The gas flow channel 21 is connected to the annular air channel 24.

[0021] In this example, gas channel 31 and liquid channel 30 are formed axially within the fluid connector 3. Gas channel 31 is evenly distributed around liquid channel 30 at intervals. Liquid channel 30 and liquid channel 22 are on the same straight line. Gas channel 21 and gas channel 31 have the same number and are on the same straight line when aligned. After the fluid connector 3 is connected to the atomizing chamber 2 at the end, gas channel 21 and gas channel 31 are connected accordingly, and liquid channel 22 and liquid channel 30 are connected accordingly. A swirl vane 4 is installed on the end face of the atomizing chamber 2 facing the fluid connector 3, and the swirl vane corresponds to liquid channel 30. The specific configuration of the swirl vane can be found in the patent with authorization publication number CN104384037B.

[0022] In this example, a positioning block 25 is radially protruding outward at the peripheral wall of the tail end of the atomizing chamber 2, and multiple positioning blocks 25 are distributed circumferentially. For example, four positioning blocks are evenly distributed circumferentially in a cross shape, corresponding to the groove 32 formed at the end face of the fluid connector. Four slots 33 are formed at the groove end face of the groove 32. The tail end of the atomizing chamber 2 is inserted into the groove 32, and the positioning block 25 is inserted into the slot 33. If the positioning block is located on the peripheral wall of one of the gas channels, then when the positioning block is inserted into the slot, the gas channel one corresponds to the gas channel two.

[0023] In this example, a rotating cylinder 6 is fitted around the peripheral wall of the fluid connector 3, and the two rotate in conjunction. The peripheral surface of the rotating cylinder 6 is threadedly engaged with the cavity wall of the corresponding nozzle 1. In this example, a ring-shaped end cap 5 is threadedly connected to the peripheral surface of the fluid connector 3 near its tail end. The peripheral wall of the fluid connector 3 is axially stepped in two stages. The rotating cylinder 6 is rotatably connected in the space between the end cap 5 and the corresponding stepped interface. In use, if the rotating cylinder 6 is fitted onto the fluid connector, and then the end cap 5 is screwed on at the tail end, the rotating cylinder is effectively limited. A threaded surface is formed on the peripheral wall of the first end of the rotating cylinder, corresponding to a meshing threaded surface formed on the cavity wall, thus securing it with threaded engagement.

[0024] To facilitate the application of force to the rotating cylinder, in this example, a circumferential groove 2 is formed on the circumferential wall at the tail end of the rotating cylinder 6, and circumferential protrusions 61 are formed at intervals on the bottom wall of the groove 2.

[0025] During installation, the atomizing chamber is fixed to the fluid connector beforehand, and then inserted into the nozzle cavity. The rotating cylinder is then threaded to connect with the nozzle cavity wall.

[0026] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
