[0004] With respect to the above-mentioned related technologies, the refrigeration mechanism in the driving host generates a large amount of heat when working, but the heat dissipation in the comparative document is only through the heat dissipation holes, and the heat dissipation effect is low. Utility Model Content

[0005] In order to improve the heat dissipation effect of a hot or cold compress host, the present application provides a hot or cold compress host.

[0006] The hot and cold compress host provided in this application adopts the following technical solution:

[0007] A hot or cold compress host, wherein a shell is provided with a heat conducting mechanism, a medium storage box for storing a medium, and a driving pump body connected to the medium storage box, and further comprises a fixed shell and a heat dissipation fan for installing the medium storage box, wherein the fixed shell and the inner wall of the shell form a heat dissipation duct for air flow, the heat conducting mechanism is located in the heat dissipation duct, and the heat dissipation fan is arranged at one end of the heat dissipation duct.

[0008] By adopting the above technical solution, when using the above hot or cold compress host, the heat-conducting mechanism works in the shell to generate heat, and the heat dissipation fan is used to draw or blow air, and the air flows rapidly in the heat dissipation duct, thereby cooling the heat-conducting mechanism installed in the heat dissipation duct. The heat dissipation fan is arranged at one end of the heat dissipation duct, so that the wind drawn into the shell or the wind blown into the shell is opposite to the heat dissipation duct, thereby improving the heat dissipation efficiency.

[0009] Optionally, the shell side wall is provided with ventilation holes penetrating the inner and outer side walls, and the ventilation holes include a first hole and a second hole respectively located at two ends of the heat dissipation duct.

[0010] By adopting the above technical solution, the ventilation holes include a first hole and a second hole, and the first hole and the second hole correspond to the two ends of the heat dissipation duct respectively, so as to ensure that the cold air from the outside can directly and efficiently enter the heat dissipation duct, thereby improving the efficiency and speed of air flow, and at the same time helping to reduce the accumulation of dust and other impurities, making the heat dissipation effect more ideal.

[0011] Optionally, the fixed shell is provided with limiting edges on both sides along the extension direction of the heat dissipation duct, and the shell is provided with a first limiting groove for the limiting edges to be sealed and inserted.

[0012] By adopting the above technical solution, the fixed shell is installed in the shell by plugging and fitting the limiting edge and the first limiting groove. At the same time, the first limiting groove and the limiting edge are sealed, so that the gap between the outer wall of the fixed shell and the inner wall of the shell can be blocked, thereby ensuring that air is transported from the heat dissipation duct.

[0013] Optionally, the shell includes a bottom shell, an annular sheet and a top cover, the fixed shell and the driving pump body are fixed to the bottom shell, the top cover is arranged on the top of the bottom shell and is snap-connected to the bottom shell, the annular sheet is arranged between the bottom shell and the top cover, the ventilation holes are located on opposite sides of the annular sheet and are arranged at intervals along the circumference of the annular sheet.

[0014] By adopting the above technical scheme, the specific composition of the shell is disclosed, the fixed shell and the driving pump body are fixed to the bottom shell, the top cover covers the bottom shell to achieve a sealing and protective effect, and the annular sheet is located between the bottom shell and the top cover. The above shell has a simple structure and is easy to assemble. Compared with opening the ventilation holes in the bottom shell or the top cover, the provision of the annular sheet can reduce the difficulty of opening the mold of the bottom shell and reduce the production cost.

[0015] Optionally, the annular sheet includes two symmetrical arc-shaped sheets and a connecting piece connecting the two arc-shaped sheets, and the connecting piece has a slot for inserting the connecting piece.

[0016] By adopting the above technical solution, the annular sheet is composed of two arc-shaped sheets, and the two arc-shaped sheets are connected and fixed by a connecting piece. Compared with the one-piece annular sheet, the assembly method of two arc-shaped sheets is adopted to reduce the assembly difficulty and production cost. The setting of the connecting piece can make the assembly more convenient.

[0017] Optionally, a protrusion is provided on the circumferential side of the arc-shaped piece, and the slot is adapted to the arc-shaped piece.

[0018] By adopting the above technical solution, the setting of the raised portion can improve the structural strength of the arc piece, increase the contact area between the end of the arc piece and the connecting piece, improve the positioning and fixing effect, improve the force distribution, avoid excessive stress concentration in a certain part, and improve the service life.

[0019] Optionally, the bottom shell has second limiting grooves for sealingly inserting the connecting member on two opposite sides of the extending direction of the heat dissipation duct.

[0020] By adopting the above technical scheme, a connection method between the connecting piece and the bottom shell is disclosed. The bottom shell is sealed and plugged with the connecting piece through the second limiting groove. The installation method is simple, so that the gap between the annular sheet and the fixed shell is blocked, ensuring that the cold air flows in the heat dissipation duct after entering from the ventilation hole, thereby improving the heat dissipation effect.

[0021] Optionally, one side of the connecting member has a first inclined surface inserted into the bottom shell, and a second inclined surface on a side away from the first inclined surface, and the inclination directions of the first inclined surface and the second inclined surface are opposite.

The setting of the second inclined surface facilitates the top cover to be buckled and fixed to the bottom cover, thereby reducing the probability of interference between the connecting member and the top cover.

[0023] Optionally, the heat dissipation fan is an exhaust fan.

[0024] By adopting the above technical solution, the heat dissipation fan is an exhaust fan, and the air in the shell is extracted through the heat dissipation fan. Under the action of negative pressure, external air enters from the vent on the side away from the heat dissipation fan, and is then discharged from the other vent along the heat dissipation duct, while driving the heat generated by the heat conduction mechanism. The laminar flow generated by the exhaust-type heat dissipation has a stable airflow and is less subject to resistance loss from the heat sink.

[0025] Optionally, the heat dissipation fan is installed obliquely on one side of the bottom shell, and the axis of the heat dissipation fan is staggered with the extension axis of the heat dissipation duct.

Meanwhile, the heat-conducting fan is an exhaust-type fan with stable airflow, which is suitable for heat-conducting mechanisms with relatively uniform heat distribution;

[0029] 2. The application can simultaneously realize the positioning installation of the fixed shell and the sealing blocking between the outer wall of the fixed shell and the inner wall of the shell body through the cooperation of the limiting edge and the first limiting groove, so as to ensure that the air flows to the heat dissipation duct;

[0030] 3. The present application can reduce production costs and improve assembly efficiency by providing arc-shaped sheets and connectors, while also blocking the gap between the annular sheet and the fixed shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The embodiment of the present application discloses a hot or cold compress host.

[0038] Reference Figure 1 and Figure 2 A hot and cold compress host comprises a housing 1, in which a heat conduction mechanism 2, a medium storage box 3 for storing a medium, a driving pump body 4 for driving the medium to flow, a fixed housing 5 for installing the medium storage box 3 and the heat conduction mechanism 2, and a heat dissipation fan 6 are arranged. The heat conduction mechanism 2 is fixed to the bottom of the fixed housing 5, and the medium storage box 3 is fixed to the top of the fixed housing 5. In the figure, the positive direction of Z is the top, and the negative direction is the bottom.

[0039] The heat conduction mechanism 2 is a semiconductor heat conduction structure in the prior art, including a semiconductor refrigeration sheet 21, a heat sink 22, and a heat conduction material 23 connecting the refrigeration sheet 21 and the heat sink 22. The semiconductor refrigeration sheet 21 is provided with a heat conduction metal plate 24 and a heat conduction pipe 25 welded to the top of the heat conduction metal plate 24 on the side away from the heat sink 22. The heat conduction metal plate 24 and the semiconductor refrigeration sheet 21 are connected by the heat conduction material 23, and the two ends of the heat conduction pipe 25 are respectively connected to the water outlet end of the medium storage box 3 and the input end of the driving pump body 4.

[0040] Reference Figure 2 and Figure 3 The housing 1 is an elliptical shell as a whole, including a bottom shell 11, an annular sheet 12 and a top cover 13 covering the bottom shell 11. The fixed shell 5 is fixed in the bottom shell 11, and a heat dissipation duct 51 for air flow is formed between the bottom of the fixed shell 5 and the bottom wall of the bottom shell 11, and both ends of the heat dissipation duct 51 penetrate the fixed shell 5. Among them, the spacing arrangement direction of the heat dissipation fins 22 is parallel to the extension direction of the heat dissipation duct 51. A snap ring 111 that snaps with the top cover 13 is integrally provided in the bottom shell 11. The snap ring 111 has snap grooves 1111 at intervals, and the top cover 13 has a clamping block 131 corresponding to the snap grooves 1111.

[0041] The heat dissipation fan 6 is an exhaust fan, which is fixed obliquely to one side of the fixed shell 5 by bolts and corresponds to one end of the heat dissipation duct 51. The heat dissipation fan 6 is tilted upward away from the bottom wall of the heat dissipation duct 51, so that the central axis of the heat dissipation fan 6 and the extension axis of the heat dissipation duct 51 are intertwined. The driving pump body 4 is fixed to the other end of the heat dissipation duct 51.

[0042] The two sides of the fixed shell 5 near one end of the driving pump body 4 abut against the inner wall of the bottom shell 11 to prevent air from flowing to the outside of the fixed shell 5. In order to further increase the sealing effect and position the fixed shell 5, the fixed shell 5 is integrally provided with limiting edges 52 on the opposite sides along the extension direction of the heat dissipation duct 51. The limiting edges 52 are located on the side of the fixed shell 5 near the heat dissipation fan 6 and extend along the Z direction. The opposite sides of the inner wall of the bottom shell 11 have first limiting grooves 1112 that are sealed with the limiting edges 52. Through the matching and plugging of the limiting edges 52 and the first limiting grooves 1112, the sealing of the two sides of the length direction of the fixed shell 5 and the inner wall of the bottom shell 11 is achieved, and the positioning and installation of the fixed shell 5 is achieved at the same time.

[0043] Reference Figure 3 and Figure 4 The annular sheet 12 is disposed between the bottom shell 11 and the top cover 13 and is in an elliptical ring shape. The annular sheet 12 includes two symmetrical arc-shaped sheets 121 and a connecting member 122 for connecting the arc-shaped sheets 121.

[0044] The opposite sides of the annular sheet 12 are provided with ventilation holes penetrating the two sides, and the ventilation holes are circular holes evenly spaced along the circumference of the annular sheet 12. The ventilation holes include a first hole 123 and a second hole 124. The first hole 123 corresponds to the air inlet of the heat dissipation duct 51, that is, it is located on the side of the annular sheet 12 close to the driving pump body 4, and the second hole 124 corresponds to the air outlet of the heat dissipation duct 51, that is, it is located on the side of the annular sheet 12 close to the heat dissipation fan 6.

[0045] The two sides of the connector 122 have slots 1221 for inserting the ends of the arc-shaped sheet 121. The arc-shaped sheet 121 has a convex portion 1211 in the circumferential direction, and the convex portion 1211 protrudes outward away from its central axis. In this embodiment, the convex portion 1211 is formed by a stamping process. The slot 1221 is adapted to the convex portion 1211, and the cross section in the Z direction is a U-shaped groove. The bottom of the slot 1221 is a sealed end, and the top passes through the top surface of the connector 122.

[0046] The connector 122 has an inserting portion 1222 on the side away from the slot 1221 for sealingly inserting with the bottom shell 11. The clamping ring 111 also has a second limiting groove 1113 for inserting the inserting portion 1222. The second limiting groove 1113 realizes the limited installation of the annular sheet 12 and the bottom shell 11, and at the same time forms a barrier to the gap between the inner wall of the bottom shell 11 and the clamping ring 111, thereby ensuring that the air entering from the first hole 123 is transported to the heat dissipation duct 51, thereby improving the air flow speed.

[0047] The top and bottom of the connecting member 122 both have inclined surfaces, the inclined surface at the bottom is the first inclined surface 1223, and the inclined surface at the top is the second inclined surface 1224. The two inclined surfaces are inclined in opposite directions to facilitate the insertion of the connecting member 122 into the second limiting groove 1113 and the buckling and fixing of the top cover 13.

[0048] The implementation principle of a hot or cold compress host in an embodiment of the present application is as follows: the heat conduction mechanism 2 is started to transfer heat to the heat-conducting metal plate 24, and the pump body 4 is driven to start to transport the fluid in the medium storage box 3 to the heat-conducting pipe 25 for heating or cooling; when the hot or cold compress host is working, the heat dissipation fan 6 is started at the same time, so that the shell 1 generates negative pressure, and air enters from the first hole 123, and then is discharged from the second hole 124 along the heat dissipation duct 51, and the heat generated by the heat sink 22 is taken out during the air flow, thereby achieving the heat dissipation effect.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
