[0030] The following will further illustrate the technical solution of the present utility model in conjunction with the attached drawings Figures 1 to 5 and through specific embodiments.

[0031] As Figures 1 - 5 shown, a glass heater convenient for assembly includes a body 1 and a heating element 2;

[0032] The body 1 includes a front shell 11, a rear shell 12, an upper limit frame, a lower limit frame 13, a left limit frame 14, and a right limit frame that are detachably connected;

[0033] The front shell 11 and the rear shell 12 are detachably connected. After the front shell 11 and the rear shell 12 are closed and connected, a cavity is formed. The heating element 2 is located in the cavity, and the front and rear sides of the heating element 2 are respectively arranged in close contact with the front shell 11 and the rear shell 12;

[0034] The upper limit frame, the lower limit frame 13, the left limit frame 14, and the right limit frame are installed between the front shell 11 and the rear shell 12. The upper and lower ends of the heating element 2 are respectively arranged in close contact with the upper limit frame and the lower limit frame 13, and the left and right ends of the heating element 2 are respectively arranged in close contact with the left limit frame 14 and the right limit frame.

[0035] By arranging the front and rear sides of the heating element 2 in close contact with the front shell 11 and the rear shell 12 respectively, the heating element 2 is limited between the upper limit frame, the lower limit frame 13, the left limit frame 14, and the right limit frame installed between the front shell 11 and the rear shell 12. The heating element 2 can be installed in the body 1 without using bolts, which is convenient for the assembly of the glass heater and the maintenance and replacement of the heating element 2 when it is damaged later.

[0036] As Figures 3 - 4 shown, two first limit grooves 111 and two second limit grooves 116 are respectively formed on the adjacent side walls of the front shell 11 and the rear shell 12. The two ends of the upper limit frame and the lower limit frame 13 are respectively clamped in the corresponding first limit grooves 111, and the left limit frame 14 and the right limit frame are respectively clamped in the corresponding second limit grooves 116.

[0037] Specifically, by means of limiting the upper limit frame and the lower limit frame 13 through the first limiting groove 111, and limiting the left limit frame 14 and the right limit frame through the second limiting groove 116, the upper limit frame, the lower limit frame 13, the left limit frame 14 and the right limit frame can be fixed between the front shell 11 and the rear shell 12 without bolts, thus shortening the disassembly and assembly time.

[0038] As Figure 2 shown, on one side of the front shell 11 facing the rear shell 12, there are provided a plurality of first threaded cylinders 112, on one side of the rear shell 12 facing the front shell 11, there are provided a plurality of second threaded cylinders 113, the inner wall of the second threaded cylinder 113 is provided with a third threaded cylinder 114, one end of the first threaded cylinder 112 far from the front shell 11 is inserted into the second threaded cylinder 113 and abuts against the outer wall of the third threaded cylinder 114, on the other side of the rear shell 12, there is provided an installation hole communicating with the second threaded cylinder 113, a bolt is inserted into the installation hole, and the bolt is threadedly inserted into the third threaded cylinder 114 and the first threaded cylinder 112.

[0039] Specifically, by means of inserting the first threaded cylinder 112 into the second threaded cylinder 113, the front shell 11 and the rear shell 12 can be quickly and accurately aligned and butted together, and by means of the bolt passing through the installation hole and being threadedly inserted into the third threaded cylinder 114 and the first threaded cylinder 112, the disassembly and assembly between the front shell 11 and the rear shell 12 can be facilitated.

[0040] As Figures 1 - 4 shown, the front shell 11 and the rear shell 12 are respectively provided with heat dissipation holes 15 communicating with the cavity, the heat generating end of the heat generating member 2 covers the heat dissipation holes 15, a plurality of the first threaded cylinders 112 are arranged around the heat dissipation holes 15, and four of the first limiting grooves 111 and four of the second limiting grooves 116 are both located between the plurality of the first threaded cylinders 112 and the heat dissipation holes 15.

[0041] Specifically, by providing the heat dissipation holes 15, it is convenient for the heat generating body 2 to radiate heat to the outside of the body 1 through the heat dissipation holes 15.

[0042] As Figure 4 shown, the outer side walls of a plurality of the first threaded cylinders 112 and the second threaded cylinders 113 are respectively provided with reinforcing ribs 115, and a plurality of the reinforcing ribs 115 are respectively fixed to the adjacent side walls of the front shell 11 and the rear shell 12.

[0043] Specifically, by providing the reinforcing ribs 115, the strength of the first threaded cylinders 112 and the second threaded cylinders 113 can be improved.

[0044] As Figure 4As shown, two third limiting grooves 141 are respectively formed in the adjacent side walls of the left limiting frame 14 and the right limiting frame, and the number of the heating elements 2 is two. The left and right ends of the two heating elements 2 are respectively clamped in the corresponding third limiting grooves 141.

[0045] Specifically, by respectively clamping the left and right ends of the heating element 2 in the corresponding third limiting grooves 141, the left and right ends of the heating element 2 can be quickly limited, and it is convenient for the disassembly and assembly of the heating element 2 with the left limiting frame 14 and the right limiting frame.

[0046] Furthermore, the number of the heating elements 2 is two, and the heating elements 2 with a smaller weight can cover the heat dissipation holes 15 of the front shell 11 and the rear shell 12, thereby reducing the weight of the glass heater.

[0047] As Figure 4 shown, a plurality of positioning plates 142 are respectively provided on the opposite side walls of the left limiting frame 14 and the right limiting frame. The positioning plates 142 are fixed between the first threaded cylinder 112 and the second threaded cylinder 113, and the first threaded cylinder 112 penetrates through the positioning plates 142.

[0048] Specifically, by the way that the first threaded cylinder 112 penetrates through the positioning plates 142, the left limiting frame 14 and the right limiting frame can be fixed to avoid the phenomenon that the left limiting frame 14 and the right limiting frame shake.

[0049] As Figure 4 shown, the heating element 2 is a heating glass, and an adhesive is bonded between the heating element 2 and the front shell 11 and the rear shell 12.

[0050] Specifically, by bonding the heating element 2 with the front shell 11 and the rear shell 12 through the adhesive, the phenomenon that the heating element 2 shakes in the machine body 1 can be avoided.

[0051] Preferably, the adhesive is a foam adhesive. The foam adhesive has good bonding performance, heat insulation effect and weather resistance, and can effectively reduce the heat transfer of the heating element 2 to the machine body 1, avoiding the phenomenon that the machine body 1 is overheated and scalding the user when touched, thereby improving the service life of the device.

[0052] As Figure 5 shown, air outlet grilles 117 and air inlet grilles 118 are respectively provided on the top and bottom side walls of the front shell 11. Through holes 131 are respectively formed in the upper limiting frame and the lower limiting frame 13. The air outlet grilles 117 and the air inlet grilles 118 are communicated with the through holes 131 and the cavity.

[0053] Specifically, air flows upward through the air inlet grille 118, the through hole 131, the cavity and the air outlet grille 117, and is heated by the heating element 2, forming a convective heat transfer of hot air rising. Heat is generated simultaneously by two methods, namely thermal radiation and thermal convection, reducing the ineffective loss of energy and increasing the heating rate.

[0054] Preferably, the adjacent heating elements 22 are spaced apart, and the minimum gap between the adjacent heating elements 22 is 10 mm. By setting the minimum gap between the adjacent heating elements 22 to 10 mm, the thickness of the heater can be made thinner while not affecting the convective heat transfer effect of the heater.

[0055] As Figure 5 shown, the air outlet grille 117 and the air inlet grille 118 and the front shell 11 are of an integrally formed structure.

[0056] Specifically, the air outlet grille 117 and the air inlet grille 118 and the front shell 11 being of an integrally formed structure can facilitate the manufacturing and processing of the front shell 11 and the assembly of the machine body 1.

[0057] The technical principle of the present utility model has been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present utility model and cannot be construed in any way as a limitation on the protection scope of the present utility model. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present utility model without creative efforts, and these embodiments will fall within the protection scope of the present utility model.
