[0029] As shown in Figs. 1-3 some embodiments of the present application disclose a freezing auxiliary device for oral cavity. The freezing auxiliary device comprises a cooling device 1 and a freezing liquid delivery device 2, the cooling device 1 comprises a flow pipeline 11; the freezing liquid delivery device 2 is communicated with the flow pipeline 11 to deliver freezing liquid to the flow pipeline 11.

[0030] Specifically, the cooling device 1 is the part of the freezing auxiliary device placed in the oral cavity. It directly plays a role of cooling in the oral cavity. The cooling device 1 is preferably made of thin material with good heat transfer effect. The cooling device 1 is small in size, easy to be placed in the oral cavity, such as around the teeth, or convenient for the teeth to bite. The freezing liquid delivered to the flow pipeline 11 of the cooling device 1 can realize the temperature reduction around the placement site and play an auxiliary anesthesia effect.

[0031] In the preferred technical scheme of the present application, the freezing auxiliary device further comprises a control device electrically connected with the freezing liquid delivery device 2, for controlling the freezing liquid delivery device 2.

[0032] Specifically, the control device can control the refrigerant delivery device 2 by manual setting in advance. By inputting control parameters, the refrigerant delivery device 2 can be controlled to start and stop, increase or decrease the delivery speed, increase or decrease the delivery flow rate, and other operations.

[0033] In particular, the control device can be a controller, a motor, or other equipment. It can also be an auxiliary control program on other equipment.

[0034] In the preferred technical solution of the present application, the refrigeration auxiliary device also includes: a detection device, which is arranged on the cooling device 1 and electrically connected to the control device, for detecting the temperature of the refrigerated liquid in the circulation pipe 11 and feeding back to the control device.

[0035] Specifically, the control device can automatically control the cooling device 1, and the data it relies on comes from the detection data of the detection device. Through a pre-set control strategy, the cooling device 1 is autonomously controlled with the support of the data fed back by the detection device.

[0036] In a preferred technical solution of the present application, the detection device includes a temperature measuring instrument, a probe of which is inserted into the circulation pipe 11 .

[0037] Specifically, the temperature measuring instrument is a device used to detect fluid temperature in real time. After its probe is inserted into the flow pipe 11, when the fluid flows through, it can monitor the fluid in real time. This is convenient, fast, and has high monitoring accuracy.

[0038] In particular, in order to improve the measurement accuracy, more probes can be provided, and the positions of the probes can be evenly distributed at multiple positions of the flow pipe 11. By comparing the temperature of each probe, accurate data can be obtained and whether any probe is damaged can be found.

[0039] In a preferred technical solution of the present application, the detection device further includes a flow meter, which is used to measure the flow rate of the liquid in the circulation pipe 11.

[0040] Specifically, a flow meter is a device used to measure fluid temperature in real time. Besides temperature, flow rate is also a crucial measurement. Temperature can be controlled by controlling the flow rate. For example, if the temperature is too low, the flow rate can be slowed down, and vice versa.

[0041] In particular, in order to improve detection accuracy, several flow meters may be provided to achieve precision detection.

[0042] In the preferred technical solution of the present application, the cooling device 1 further includes: a U-shaped body 12 , and the flow pipe 11 is arranged in the U-shaped body 12 .

[0043] Specifically, the U-shaped body 12 cannot be too thick and should adopt a material with good heat dissipation effect. The U-shaped body is beneficial to the circulation of fluid, saves space, and has good cooling effect.

[0044] In the preferred technical solution of the present application, the U-shaped body 12 is a thin-walled shell, and the flow-through pipeline 11 is a U-shaped spiral coil that enters from one side of the U-shaped body 12 and extends out from the other side after multiple bending.

[0045] Specifically, the U-shaped body 12 naturally adopts a thin-walled shell for the purpose of improving the refrigeration effect. The flow-through pipeline 11 adopts a U-shaped spiral coil, which is a very space-saving method to increase the volume of fluid. Thus, the fluid flow per unit area is large, and the cooling time is controllable. In the case of using a U-shaped spiral coil for the flow-through pipeline 11, the setting of the fluid inlet and outlet of the U-shaped body 12 is not limited.

[0046] As shown in Figs. 1 to 2 In the preferred technical solution of the present application, the U-shaped body 12 includes a first side plate 121, a second side plate 122, and a connecting plate connecting the first side plate 121 and the second side plate 122, the first side plate 121 and the second side plate 122 are formed as U-shaped side plates, the cross section of the first side plate 121 and the second side plate 122 is a H-shaped cross section shape, the connecting part of the first side plate 121 and the second side plate 122 is provided with an inlet 123 and an outlet 124, and the flow-through pipeline 11 extends from the inlet 123, passes through the first side plate 121 and the second side plate 122, and then extends to the outlet 124 to form a double-U-shaped fluid passage.

[0047] Specifically, the first side plate 121 and the second side plate 122 both include an arc-shaped part and a straight part, and the arc-shaped parts of the two are combined together to form a U-shaped shape, which is the shape of the entire body structure. The inner sides of the first side plate 121 and the second side plate 122 are connected with a connecting plate, which is fixed by welding, for example. The first side plate 121 and the second side plate 122 both have flow-through pipelines 11, and the connecting plate away from the arc-shaped side also has a flow-through pipeline 11 to keep the flow-through pipelines 11 inside the entire U-shaped body 12 unobstructed. The fluid inflow opening and outflow opening, i.e. the inlet 123 and the outlet 124, are both arranged on the arc-shaped side, the inlet 123 communicates with the flow-through pipeline 11 in the first side plate 121, and the outlet 124 communicates with the flow-through pipeline 11 in the second side plate 122. This arrangement forms a very thin overall U-shaped body 12, saves materials, and the fluid flows through the entire U-shaped body 12 uniformly and widely, so the refrigeration effect is good.

[0048] In particular, the flow-through pipeline 11 starts from the inlet 123, forms a U-shaped bending channel in the first side plate 121, and also forms a bending channel in the second side plate 122 until it communicates with the outlet 124 to form a double-U-shaped fluid passage.

[0049] In the preferred technical solution of the present application, the refrigeration auxiliary device further comprises a filter screen arranged at the inlet for filtering impurities of the inflowing fluid.

[0050] Specifically, the filter screen is mainly used to keep the flow channel 11 inside the U-shaped body 12 unobstructed. The inflow and outflow openings of the fluid, i.e. the inlet 12, are filtered of impurities to prevent the flow channel 11 from being blocked due to the presence of impurities.

[0051] In the preferred technical solution of the present application, the refrigeration auxiliary device further comprises a handle arranged on the cooling device 1 for holding the cooling device 1.

[0052] Specifically, after the handle is installed, the position of the cooling device 1 can be conveniently controlled, facilitating subsequent operation.

[0053] The refrigeration auxiliary device for oral cavity provided by the present application realizes real-time flow control of the refrigeration liquid by designing the cooling device 1 and the refrigeration liquid delivery device 2, controlling the delivery speed and flow of the refrigeration liquid to control the temperature of the cooling device 1, so that the temperature in the oral cavity is controllable, and the refrigeration injury is reduced.

[0054] The refrigeration auxiliary device for oral cavity is also designed with a temperature measuring instrument and a flow meter, which accurately realizes the control of the flow rate and temperature of the cooling liquid, and achieves good cooling effect.

[0055] The U-shaped spiral coil pipe can realize more flow in smaller space, improving the cooling effect.

[0056] The design of the I-shaped cross-sectional shape facilitates the occlusion of the upper and lower teeth, is more suitable for the teeth, and achieves good cooling effect.
