[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] like Figure 1-3 As shown, the utility model provides a high-pressure spray unit for ice cream, comprising a cylinder body 1, a piston rod 16 that can extend downwardly is arranged inside the cylinder body 1, the lower end of the cylinder body 1 is provided with connecting pipes 5 connected end to end along the axial direction, the lower end of the lowermost connecting pipe 5 is connected to the spray valve body 7, an axially movable pressurizing rod 15 is arranged inside the end-to-end connecting pipes 5, the upper end of the pressurizing rod 15 is connected to the piston rod 16, a pressurizing chamber 14 is formed between the lower end of the pressurizing rod 15 and the spray valve body 7, a valve block 8 with a hole in the middle is installed inside the spray valve body 7, the lower end of the spray valve body 7 is provided with an air jet 11, the upper end of the air jet 11 is provided with a valve ball 10, and a spring 12 is provided between the valve ball 10 and the valve block 8.

[0018] Specifically, after the rodless cavity in the cylinder body 1 enters the high-pressure gas, the piston rod 16 can extend downward, driving the pressurizing rod 15 to move in the inner hole of the connecting pipe 5, which will compress the air in the pressurizing cavity 14 and push the air into the spray valve body 7. The valve block 8 plays a role in guiding the flow. The high-pressure air moves faster after passing through the valve block 8. The high-pressure air moves to the bottom of the valve ball 10 and pushes the valve ball 10 upward, compressing the spring 12, and finally ejected from the air jet 11. The pressure and gas volume of the ejected gas can be precisely controlled. The ejected gas is sprayed onto the chocolate, which can atomize the chocolate.

[0019] After the rod chamber of the cylinder body 1 is filled with air, the piston rod 16 can be retracted upward, and the pressurizing rod 15 is also retracted upward, thus forming a cycle. The lower end of the spray valve body 7 is directly connected to the raw material pipe, and no polluted air from the outside is sucked into the pressurizing chamber 14.

[0020] In this embodiment, a pneumatic reversing valve 2 is mounted on the exterior of the cylinder body 1. This pneumatic reversing valve 2 is connected to an external high-pressure gas source and, via pipelines, is connected to the rodless chamber air pipe 4 and the rod chamber air pipe of the cylinder body 1. This pneumatic reversing valve 2 enables rapid alternating exhaust and intake of air between the rod chamber and the rodless chamber of the cylinder body 1, ensuring spray efficiency. Furthermore, a quick exhaust valve 3 is mounted on the rod chamber air pipe. The pneumatic reversing valve 2 is connected to the quick exhaust valve 3, increasing the exhaust velocity of the rod chamber when the piston rod 16 is depressed, ensuring that high-pressure gas can be generated in the pressurized chamber 14.

[0021] In this embodiment, if Figure 2 As shown, adjacent connecting pipes 5 and the connecting pipe 5 and the spray valve body 7 are connected via a clamp 6 , and an axial sealing ring 9 is installed inside the clamp 6 at the connection point.

[0022] In this embodiment, if Figure 2 As shown, the central hole of the valve block 8 is a conical hole with a large diameter at the upper end and a small diameter at the lower end. The conical hole can increase the speed of the high-pressure gas.

[0023] In this embodiment, if Figure 2 As shown, an adjusting seat 18 is installed at the upper end of the cylinder body 1, and an adjusting screw 17 is vertically installed at the upper end of the adjusting seat 18. The lower end of the adjusting screw 17 passes through the upper end of the cylinder body 1 and is inserted into the rodless cavity of the cylinder. The adjusting screw 17 can be raised and lowered by rotating the adjusting screw 17. When the upper end of the piston rod 16 in the cylinder is against the adjusting screw 17, it cannot rise. Therefore, the raising and lowering of the adjusting screw 17 can control the stroke of the piston rod 16, thereby controlling the stroke of the piston rod 16 each time it is pressed down, and controlling the amount of high-pressure gas ejected from the jet port 11, thereby controlling the spray amount of the raw material.

[0024] In this embodiment, an O-ring 19 is provided on the outer side of the lower end of the pressurizing rod 15 . The O-ring 19 can improve the sealing performance of the pressurizing chamber 14 .

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0027] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
