[0027] The following will be described in detail Figures 1-3 The present application will be described in detail.

[0028] Embodiments

[0029] By Figures 1-3 It can be seen that a face cooling fan machine comprises a shell 1, a plug 18 connected to a power source, and is electrically driven by connecting the plug 18 to the power source. Compared with the existing handheld small fan machine, the problem of fast battery consumption can be avoided. It also comprises a fan blade 7 installed inside the shell 1, and a motor for driving the fan blade 7 to rotate. The inside of the shell 1 is also provided with a refrigeration assembly and a cooling assembly, and the cooling assembly and the refrigeration assembly are sequentially located at the rear end of the fan blade 7. The refrigeration assembly plays a preliminary refrigeration role, and the cooling assembly plays a further refrigeration role on the basis of the refrigeration assembly.

[0030] A telescopic support rod 16 is installed on the outer wall of the shell 1, and a support seat 17 is installed at the bottom of the support rod 16. The support rod 16 can be telescoped and adjusted according to the actual use, so that the patient does not need to hold the fan for blowing and cooling, thereby reducing the burden on the patient and avoiding causing the patient's arm to be sore, numb and swollen. Moreover, there are various ways of telescopic adjustment, and only the folding and shrinking way is provided Figure 1 herein for reference. The support seat 17 plays a role of stable support, and the support seat 17 can be placed on the ground or hung on the wall, so as to meet the actual use requirements.

[0031] The outside air enters the shell 1 through the air inlet 20 on the shell 1 to be cooled and cooled, and finally the cold air is discharged from the air outlet 23 on the cover body 8 to cool the face of the patient.

[0032] The refrigeration assembly comprises a semiconductor refrigeration chip 2 mounted on the shell 1, and the model of the semiconductor refrigeration chip 2 is not specifically limited here and can meet the actual use requirements.

[0033] The principle of the semiconductor refrigeration chip 2 is mainly based on the thermoelectric effect, especially the Peltier effect, which is a phenomenon of heat transfer between two different semiconductor materials through direct current. When direct current passes through a thermocouple composed of P-type and N-type semiconductor materials in series, heat absorption and release will occur at both ends of the thermocouple. Specifically, the junction where the current flows from the N-type semiconductor to the P-type semiconductor will absorb heat and become the cold end, while the junction where the current flows from the P-type semiconductor to the N-type semiconductor will release heat and become the hot end.

[0034] The heat absorption and release is proportional to the size of the current and the number of element pairs of the semiconductor materials N and P, that is, the larger the current and the more the number of element pairs, the more obvious the refrigeration or heating effect.

[0035] Therefore, the semiconductor refrigeration chip 2 has small noise compared to the mechanical rotation of the fan blades for heat dissipation.

[0036] The specific installation method is that the cold end of the semiconductor refrigeration chip 2 is located inside the shell 1, and a plurality of heat-conducting rectangular fins 3 are mounted on the cold end. The rectangular fins 3 transfer and disperse the temperature of the cold end of the semiconductor refrigeration chip 2 to the inside of the shell 1, and the model is not specifically limited here and can meet the actual use requirements.

[0037] The electrical connection between the semiconductor refrigeration chip 2 and the plug 18 connected to the power supply is a routine technical means for those skilled in the art, and will not be described in detail here. In addition, the fan blades 7 can be connected with a wind speed adjusting module to control the wind power, and the semiconductor refrigeration chip 2 can be connected with a voltage control module, and the wind speed adjusting module and the power of the semiconductor refrigeration chip 2 are synchronized to maximize the efficiency, which will not be described in detail here.

[0038] In addition, the hot end of the semiconductor refrigeration chip 2 located outside the shell 1 is covered with a protective cover 4 to prevent the patient or staff from being scalded by accidentally touching the hot end of the semiconductor refrigeration chip 2, and the protective cover 4 and the shell 1 can be detachable. Figure 3 As shown, the connection between the two can be achieved by using elastic clamps, which is a routine technique and will not be described in detail here. In addition, other normal working methods can also be used.

[0039] The cooling assembly comprises a box 5 for storing cooling medium, and the cooling medium in the box 5 can be ice or dry ice. The outer wall of the box 5 is sleeved with a plurality of annular fins 6 at equal intervals, and the cooling medium in the box 5 is transferred to the annular fins 6, which further cools and cools the air.

[0040] The temperature of the cold end of the semiconductor refrigeration chip 2 is transmitted to the inside of the shell 1 through the rectangular fin 3, so that the air entering through the air inlet 20 is preliminarily cooled. Then the air is in contact with the annular fin 6 of the outer wall of the box 5, and is further cooled, and finally is discharged from the air outlet 23 to cool the patient's face.

[0041] In addition, the bottom of the box 5 is also provided with a positioning lug 19 which is inserted and matched with the positioning groove 21 at the bottom of the inner wall of the shell 1. The positioning lug 19 is arranged to facilitate the positioning of the box 5 in the shell 1, and plays a role of rapid positioning.

[0042] The top of the box 5 is provided with a sealing plug 9 which plays a sealing role. The sealing plug 9 is arranged to prevent the cooling medium in the box 5 from being discharged from the opening.

[0043] By Figure 2 It can be seen that the sealing plug 9 is movably provided with a latch 14 which penetrates the sealing plug 9 and is inserted into the inner wall groove of the box 5. The latch 14 is also provided with a first compression spring 13 for abutting the latch 14 against the inner wall groove of the box 5. The shape of the latch 14 is matched with the shape of the inner wall groove of the box 5, and the elastic force of the first compression spring 13 tightly inserts the latch 14 into the inner wall groove of the box 5.

[0044] The sealing plug 9 is connected with the box 5 by the latch 14. When the sealing plug 9 is pulled, the positioning lug 19 of the box 5 is also separated from the positioning groove 21, that is, the box 5 is taken out for subsequent addition of cooling medium. The standby box 5 filled with cooling medium can be reinserted into the shell 1.

[0045] The sealing plug 9 is mounted with a driving assembly. The driving assembly can separate the latch 14 from the inner wall groove of the box 5, and separate the sealing plug 9 from the box 5.

[0046] The driving assembly includes a movable rod 11 mounted in the top through hole of the sealing plug 9, a second compression spring 15 sleeved on the movable rod 11 and mounted on the sealing plug 9, a cavity 22 communicating with the top through hole of the sealing plug 9, a connecting rod 12 mounted in the cavity 22, the end of the movable rod 11 connected with the connecting rod 12, and the two ends of the connecting rod 12 inserted and matched with the latches 14. The connecting rod 12 can simultaneously act on the two latches 14, which saves time and labor and is convenient for the operator to operate.

[0047] And, the connecting rod 12 two ends are bevel-shaped, so that the staff moves the rod 11 down, at this time the second compression spring 15 is elastically deformed under the action of external force, the bevel generates a component force to drive the bolt 14 to disengage from the inner wall groove of the box 5, at this time the first compression spring 13 is elastically deformed under the action of the bolt 14. At this time, pulling the handle 10 up can disengage the sealing plug 9 from the opening of the box 5, and the cooling medium is added. After the cooling medium is added, the sealing plug 9 is inserted into the opening of the box 5 again, and when inserted into the corresponding position, the bolt 14 is inserted into the inner wall groove of the box 5 again to be fixed.

[0048] In addition, the sealing plug 9 is also provided with the handle 10, and the handle 10 can be provided with two, so as to facilitate the staff to operate with both hands.

[0049] Specifically, when the face cooling fan machine is used, the plug 18 is connected to the power supply, the fan blade 7 and the semiconductor refrigeration chip 2 are started, the semiconductor refrigeration chip 2 starts refrigeration work, and the temperature of the cold end of the semiconductor refrigeration chip 2 is transmitted to the inside of the shell 1 through the rectangular fin 3, so that the air entering through the air inlet 20 is preliminarily cooled. Subsequently, the air contacts the annular fin 6 on the outer wall of the box 5, and is further cooled and cooled, and finally is discharged from the air outlet 23 under the rotation of the fan blade 7, so as to cool the face of the patient.

[0050] When the cooling medium in the box 5 needs to be consumed, the staff can pull the sealing plug 9, and the positioning lug 19 of the box 5 is disengaged from the positioning groove 21, that is, the box 5 is taken out for subsequent addition of the cooling medium. At this time, the standby box 5 filled with the cooling medium can be inserted into the shell 1 again.

[0051] When the sealing plug 9 needs to be disengaged from the box 5, the staff can press down the movable rod 11, at this time the second compression spring 15 is elastically deformed under the action of external force, the bevel generates a component force to drive the bolt 14 to disengage from the inner wall groove of the box 5, at this time the first compression spring 13 is elastically deformed under the action of the bolt 14. At this time, pulling the handle 10 up can disengage the sealing plug 9 from the opening of the box 5, and the staff can add the cooling medium.

[0052] After the cooling medium is added, the sealing plug 9 can be inserted into the opening of the box 5 again, and when inserted into the corresponding position, the bolt 14 is inserted into the inner wall groove of the box 5 again to be fixed.

[0053] The above is only a preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
