DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0034] For example Figures 1-7As shown, the utility model provides a kind of liquid cooling heat dissipation bulb, including lamp body 1, glass cover 2 and base 3, the lamp body 1 is connected in the base 3, the glass cover 2 is sleeved in one end of the lamp body 1 and the end of glass cover 2 extends into the base 3, so that the glass cover 2 forms airtight space 21 in, the working end of the lamp body 1 is located in the airtight space 21, and the glass cover 2 with the base 3 is detachably connected;The base 3 is also provided with the liquid cooling chamber 4 formed by the inner wall of the base 3 and the outer wall of the glass cover 2, and the base 3 is also provided with water inlet channel 41 and drain channel 42 communicated with the liquid cooling chamber 4 respectively;

[0035] When using, the lamp body 1 is in working condition, cooling liquid enters into the liquid cooling chamber 4 from the water inlet channel 41 and fills the entire liquid cooling chamber 4, so that the cooling liquid can be fully contacted with the glass cover 2 and the base 3 and absorb heat, and then the cooling liquid is discharged from the drain channel 42 outside the bulb;Through the continuous flow of cooling liquid, the heat of the base 3 and the glass cover 2 is continuously taken away, so that the entire bulb can be kept at stable working temperature for continuous work, not only effectively improving the working stability of the bulb, but also further improving the service life of the bulb.

[0036] Specifically, in the embodiment, the base 3 includes detachably connected upper seat 31, middle seat 32 and lower seat 33 from top to bottom, the upper seat 31 and the middle seat 32, and the lower seat 33 and the middle seat 32 are fixed by bolts 34;Among them, the liquid cooling chamber 4 is enclosed by the upper seat 31, the middle seat 32 and the glass cover 2, since the liquid cooling chamber 4 is composed of multiple parts, the gap between each part is easy to cause the risk of cooling liquid leakage, therefore the sealing structure in the base 3 is crucial, and the sealing structure also needs to ensure that the overall installation of the bulb is convenient;

[0037] To solve the technical problem, as Figure 8As shown, in the present embodiment, the liquid cooling chamber 4 is provided with a packing ring 5 sleeved on the glass cover 2, the packing ring 5 is provided with a plurality of communication holes 51, a first sealing ring 432 is arranged between the top of the packing ring 5 and the top wall of the liquid cooling chamber 4, and a second sealing ring 442 is arranged between the bottom of the packing ring 5 and the bottom wall of the liquid cooling chamber 4; that is, during the liquid cooling process, the cooling liquid can fully contact the glass cover 2 through the communication holes 51 to absorb heat, at the same time, the first sealing ring 432 is tightly pressed by the bottom of the upper seat 31, the top of the packing ring 5 and the circumferential wall of the glass cover 2, thereby effectively ensuring the sealing performance of the upper part of the liquid cooling chamber 4; at the same time, the second sealing ring 442 is tightly pressed by the bottom wall of the liquid cooling chamber 4 in the upper seat 31, the bottom of the packing ring 5 and the circumferential wall of the glass cover 2, thereby effectively ensuring the sealing performance of the lower part of the liquid cooling chamber 4.

[0038] Therefore, during installation, the first sealing ring 432, the packing ring 5 and the second sealing ring 442 can be sleeved on the glass cover 2 in sequence, due to the fastening force of the first sealing ring 432 and the second sealing ring 442, the packing ring 5 can be stably fixed on the glass cover 2, thereby facilitating the installation of the glass cover 2 and the base 3; then the glass cover 2 is inserted into the base 3, so that the first sealing ring 432, the packing ring 5 and the second sealing ring 442 are located in the liquid cooling chamber 4, finally the upper seat 31 is covered and the upper seat 31 and the middle seat 32 are fixed by the bolts 34, at this time, the upper seat 31 and the middle seat 32 are close to each other and jointly press the first sealing ring 432 and the second sealing ring 442 in the liquid cooling chamber 4, thereby further improving the pressing force of the first sealing ring 432 and the second sealing ring 442 and the sealing performance of the liquid cooling chamber 4, so that the lamp has good assembly and disassembly convenience, and the liquid cooling chamber 4 has good sealing effect.

[0039] Specifically, as Figure 9As shown, in order to enable the first sealing ring 432 and the second sealing ring 442 located in the liquid cooling chamber 4 to actively approach and compress the peripheral wall of the glass cover 2 to improve the sealing performance of the liquid cooling chamber 4, the top of the clamping ring 5 is provided with a first inclined surface 52, and the top wall of the liquid cooling chamber 4 is provided with a second inclined surface 431. The first inclined surface 52, the second inclined surface 431, and the glass cover 2 together form a gap 43 with a trapezoidal cross-sectional structure. The first sealing ring 432 is located within the gap 43 and... Inside, the vertical distance D1 near one end of the glass cover 2 is greater than the vertical distance D2 at the other end; through the trapezoidal structure, when the upper seat 31 and the middle seat 32 are pressed up and down, the first sealing ring 432 is pressed up and down by the second inclined surface 431 and the first inclined surface 52, and moves towards the glass cover 2 under the guidance of the two inclined surfaces, and finally seals and presses between the three-sided structure of the glass cover 2 peripheral wall, the first inclined surface 52 and the second inclined surface 431, thereby ensuring the sealing of the upper part of the liquid cooling chamber 4;

[0040] Similarly, the bottom of the clamping ring 5 is provided with a third inclined surface 53, and the bottom wall of the liquid cooling chamber 4 is provided with a plane 441. The third inclined surface 53, the plane 441, and the glass cover 2 together form a gap 44 with a right-angled trapezoidal cross-section. The second sealing ring 442 is located within the gap 44. At the same time, within the gap 44, the vertical distance D3 near one end of the glass cover 2 is greater than the vertical distance D4 at the other end. This causes the second sealing ring 442 to be subjected to vertical compression by the third inclined surface 53 and the plane 441 when the upper seat 31 and the middle seat 32 are pressed together. Under the guidance of the two inclined surfaces, it moves towards the glass cover 2 and finally seals and is pressed between the three-sided structure of the glass cover 2, the third inclined surface 53, and the plane 441, thereby ensuring the sealing of the lower part of the liquid cooling chamber 4.

[0041] Specifically, such as Figure 10 As shown, due to the arrangement of the clamping ring 5, the filling space of the coolant in the liquid cooling chamber 4 is reduced. Therefore, in order to further increase the filling space of the coolant, the inner peripheral wall of the clamping ring 5 is provided with an inwardly recessed groove 54, and the outer peripheral wall of the clamping ring 5 is provided with an inwardly recessed groove 55. The inner groove 54 and the outer groove 55 are connected through the connecting hole 51. Through the arrangement of the inner groove 54 and the outer groove 55, the clamping ring 5 is able to ensure good contact force with the first sealing ring 432 and the second sealing ring 442, while effectively increasing the filling space of the coolant in the liquid cooling chamber 4, further increasing the contact area between the coolant and the glass cover 2 and the base 3, and improving the heat dissipation efficiency of both.

[0042] Specifically, as shown in Figures 10-11 The end of the glass cover 2 is provided with an opening 22, and the base 3 is provided with an air chamber 6 in communication with the opening 22, so that the air chamber 6 is in communication with the sealed space 21. The air chamber 6 is provided with a support 61 for supporting the end wall of the opening 22.

[0043] Further, the top of the support 61 is provided with a plurality of protrusions 62, and the air holes 63 are formed between adjacent protrusions 62. The air holes 63 are in communication with the air chamber 6. The base 3 is further provided with an air pipe 64 in communication with the air holes 63.

[0044] In use, the user can connect an air pump (not shown) to the end of the air pipe 64. The air pump sequentially performs vacuumizing and gas filling processes on the sealed space 21 in the glass cover 2 through the air holes 63 and the air chamber 6. During the gas filling process, the user can fill different gases to change the light emitting brightness, heat amount, light color and other properties of the lamp body 1 under the reaction of different gases, so that the user can change the light emitting brightness, heat amount, light color and other properties of the lamp body 1 according to the heating needs of the object to be heated, thereby improving the convenience and flexibility of the lamp.

[0045] Specifically, as shown in Figures 12-13 The lamp body 1 includes a filament 11 and two parallelly arranged pins 12. The two ends of the filament 11 are respectively connected to the ends of the two pins 12. Since the lamp in the prior art is of an integrated structure, and the filament 11 is a consumable product with a short service life, the replacement frequency of the lamp is high during heating, which leads to an increase in the maintenance and replacement cost of the lamp and the heating cost. In the embodiment, the filament 11 and the pin 12 are detachably connected, that is, during the maintenance of the lamp, only the glass cover 2 needs to be removed to realize the separate disassembly and replacement of the filament 11.

[0046] Further, the end of the pin 12 is provided with a detachable fixing member 13. The detachable connection mode can be threaded connection, clamping, screw connection, or integral connection. The fixing member 13 is provided with a mounting hole 131 coaxially arranged with the pin 12. The side wall of the fixing member 13 is provided with at least one fixing hole 132 in communication with the mounting hole 131. The fixing hole 132 is screwed with a screw 14.

[0047] When installing, one end of the fixing member 13 is connected with the pin 12, and the filament 11 is inserted into the fixing member 13 from the mounting hole 131 at the other end of the fixing member 13, at this time, the screw 14 is tightened, so that the end of the screw 14 in the fixing hole 132 can press and fix the filament 11 in the mounting hole 131, thereby realizing the fixation and detachable connection of the filament 11; in the embodiment, the detachable connection structure of the fixing member 13 and the filament 11 is simple, and the assembly parts are less, so that the maintenance and replacement convenience of the filament 11 can be effectively improved; at the same time, since the winding shape, thickness and material of different filaments 11 can affect the heating effect of the filament 11, through the detachable connection of the filament 11 and the pin 12, the user can replace the filament 11 according to the heating demand, thereby improving the practicability of the bulb.

[0048] Preferably, the end of the pin 12 away from the filament 11 is inserted into the lower seat 33, and the pin 12 and the lower seat 33 can be fixed by filling with sealing material or vacuum welding, thereby ensuring the air tightness of the air chamber 6.

[0049] The innovation of the utility model lies in that the packing ring, the first sealing ring and the second sealing ring are arranged in the liquid cooling chamber, the first sealing ring and the second sealing ring are fixed by three sides, the sealing of the liquid cooling chamber is realized, the liquid cooling chamber has good sealing property and the dismounting convenience of the glass cover is effectively improved; meanwhile, through the detachable design of the filament and the design that the air pipe is communicated with the closed space, the user can replace the filament and perform vacuumizing or gas filling according to the heating demand, thereby improving the practicability and use flexibility of the bulb.

Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than by the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
