[0002] The ultraviolet lamp device structurally includes a housing. Inside the housing, a quartz lamp tube storing inert gas is provided. Electrodes are arranged inside the tube of the quartz lamp tube, and both ends of the electrodes are respectively placed at both ends of the quartz lamp tube. By using the electrodes to provide a voltage drop, the inert gas inside the quartz lamp tube generates ionic discharge, thereby emitting ultraviolet rays.

[0003] In the existing ultraviolet lamp device solutions, for the structure of the quartz lamp tube, deviations will occur during the firing process of the existing quartz lamp tube, which will make it difficult to fit the quartz lamp tube during the assembly with the electrodes.

As shown in Figure 3 it shows that the arc part of the electrode is difficult to completely fit with the quartz lamp tube. However, in applications, only the fitting part of the electrode and the quartz lamp tube can generate ultraviolet rays.

[0004] In addition, in Figure 3 for the positioning of the electrodes, after using the electrode support, the maximum width of the combination of the electrodes and the electrode support is equal to the diameter of the tube of the quartz lamp tube, so that the electrodes can be positioned. Furthermore, it can be known that the electrode support used to position the electrodes occupies a large space inside the tube, and its cooling effect on the electrodes will also be affected to a certain extent.

[0038] In order to better elaborate the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0039] It should be clear that the described embodiments are only a part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative work belong to the scope protected by the embodiments of this application.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. On the contrary, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects and do not have to be used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] In the existing ultraviolet lamp device solutions, for the structure of the quartz lamp tube, deviations will occur during the firing process of the existing quartz lamp tube, which will make it difficult to fit the quartz lamp tube when assembling with the electrode. For example, Figures 1 to 3 As shown in the partial structure of the existing ultraviolet lamp device, in order to adapt to the structure of the quartz lamp tube a, it is necessary to miniaturize the arc of the electrode c shown in the figure, and then install it in the tube of the quartz lamp tube a in cooperation with the electrode bracket b. As shown in Figure 1 It shows that the arc part of the electrode c is difficult to completely fit with the quartz lamp tube a. However, in application, only the fitting part of the electrode c and the quartz lamp tube a can generate ultraviolet rays.

[0044] In addition, in Figure 3In it, for the positioning of the electrode c, after using the electrode support b, only when the widest width after the combination of the electrode c and the electrode support b is equal to the diameter of the tube of the quartz lamp tube a can the electrode c be positioned. Furthermore, it can be known that the electrode support b used to position the electrode c occupies a large space inside the tube, and its cooling effect on the electrode c will also be affected to a certain extent.

[0045] Therefore, the technical problem actually solved by this application lies in improving the positioning structure of the electrode assembly in the ultraviolet lamp device.

[0046] As a preferred embodiment of this application, as Figure 4 shown, an ultraviolet lamp device includes:

[0047] A cylindrical quartz lamp tube 1, and a channel 101 is configured in the middle of the quartz lamp tube 1;

[0048] An electrode assembly 2 with a shape matching that of the quartz lamp tube 1, such as the electrode assembly 2 with a semi-cylindrical main body shown in Figure 4 wherein the electrode assembly 2 is arranged at the position of the channel 101, and the electrode assembly 2 is configured to abut against the upper edge and the lower edge of the electrode assembly 2 through an elastic member 3, so that the upper edge and the lower edge of the electrode assembly 2 are in close contact with the inner peripheral wall of the quartz lamp tube 1, and further the whole electrode assembly 2 is fully attached to the inner peripheral wall of the quartz lamp tube 1, which is beneficial to the generation of ultraviolet rays.

[0049] An ultraviolet lamp device of the present utility model includes a quartz lamp tube 1 and an electrode assembly 2 with a shape matching that of the quartz lamp tube 1. The electrode assembly 2 is arranged at the position of the channel 101. By configuring the electrode assembly 2 to abut against the upper edge and the lower edge of the electrode assembly 2 through an elastic member 3, the upper edge and the lower edge of the electrode assembly 2 are in close contact with the inner peripheral wall of the quartz lamp tube 1. Furthermore, after the electrode assembly 2 is assembled with the quartz lamp tube 1, no edge gap will be generated, which is beneficial to the generation of ultraviolet rays. Moreover, under the condition that the upper edge and the lower edge of the electrode assembly 2 are in close contact with the inner peripheral wall of the quartz lamp tube 1, the electrode assembly 2 is horizontally positioned inside the quartz lamp tube 1. When fixing the electrode assembly 2 with an external support, it can be avoided that the external support extends into the channel 101 for fixing, which is beneficial to providing a sufficient ventilation path for cooling the electrode assembly 2.

[0050] Preferably, the elastic member 3 is one of a torsion spring, a snap ring or a spring.

[0051] When the elastic member 3 is a snap ring, the snap ring is usually a flat spring piece or a coiled helical spring piece, and it is embedded in the fixed position to play a role in fixing or adjusting the axial position;

[0052] When the elastic member 3 is a spring, the spring can be in the shape of a helix, rod, plate, lock spring, etc. Its function is to store elastic potential energy by relying on internal elastic deformation, so as to play roles such as shock absorption, support, and ejection.

[0053] When the elastic member 3 is a torsion spring, a sufficient elastic thrust is provided by the torsion spring, and the torsion spring is not easily deformed, which is preferably used in this embodiment.

[0054] In this embodiment, the electrode assembly 2 adopts a split structure, such as Figure 4 shown, the electrode assembly 2 includes:

[0055] an arc-shaped upper electrode 21 and an arc-shaped lower electrode 22, and the lower electrode 22 is assembled and connected to the upper electrode 21;

[0056] The elastic member 3 is arranged between the upper electrode 21 and the lower electrode 22, and the upper end and the lower end of the elastic member 3 are respectively in close contact with the upper electrode 21 and the lower electrode 22.

[0057] For the connection method between the upper electrode 21 and the lower electrode 22: the upper electrode 21 is provided with a fixing portion 211; the lower electrode 22 is provided with a ring groove portion 221;

[0058] The fixing portion 211 is placed in the ring groove portion 221 to assemble and connect the upper electrode 21 and the lower electrode 22.

[0059] The lower end edge of the upper electrode 21 extends inward to form a first portion 212, and a "C"-shaped fixing portion 211 is formed by an outward arc-shaped extension from the end of the first portion 212;

[0060] Similarly, the lower end edge of the lower electrode 22 extends inward to form a second portion 222. The second portion 222 is opposite to the first portion 212 in position, and a "C"-shaped ring groove portion 221 is formed by an outward arc-shaped extension from the end of the second portion 222; in terms of size, the ring groove portion 221 is larger than the fixing portion 211, so that the fixing portion 211 can be placed in the ring groove portion 221;

[0061] Furthermore, it can be realized that the upper electrode 21 is inserted into the ring groove portion 221 through the fixing portion 211 in the extending direction of the lower electrode 22 for combined connection. When the electrode assembly 2 is in the current combined connection state, the upper electrode 21 and the lower electrode 22 can only be separated by horizontal movement in their respective extending directions and cannot be separated in the vertical direction, having a certain combined structure stability.

[0062] In addition, when the elastic member 3 merely abuts against the upper electrode 21 and the lower electrode 22, the first part 212 of the upper electrode 21 and the second part 222 of the lower electrode 22 support each other as platforms. When they are abutted by the elastic member 3, they will not be accidentally displaced, and thus the upper electrode 21 and the lower electrode 22 can be fully attached to the inner wall of the quartz lamp tube 1 respectively.

[0063] Regarding the positioning method of the elastic member 3, as Figure 5 shown, clamping grooves are formed on both the upper electrode 21 and the lower electrode 22; after the upper electrode 21 and the lower electrode 22 are assembled, the two clamping grooves are opposite in position, and the elastic member 3 is installed between the two clamping grooves.

[0064] In this embodiment, the electrode assembly 2 further includes:

[0065] an electrode bracket 23, the electrode bracket 23 is located at both ends of the quartz lamp tube 1, and the electrode bracket 23 is used to position the upper electrode 21 and the lower electrode 22 in the channel 101.

[0066] As Figure 4 shown, since the electrode bracket 23 does not extend into the channel 101 for fixation, enough ventilation paths are reserved in the channel 101, which is beneficial to cooling the electrode assembly 2.

[0067] In this embodiment, according to the aforementioned cooling of the electrodes, as a specific example in this embodiment, as Figure 5 shown, the ultraviolet lamp device further includes a heat dissipation assembly 5 provided at both ends of the quartz lamp tube 11, and the heat dissipation assembly 5 is used to dissipate heat from the electrodes and the quartz lamp tube 11.

[0068] Specifically, the heat dissipation assembly includes:

[0069] a heat dissipation member 51, the heat dissipation member 51 is disposed closely around the outer periphery of the quartz lamp tube 1;

[0070] a flow guide member 52, the flow guide member 52 is installed at one end of the quartz lamp tube, one end of the flow guide member 52 communicates with the channel 101, a connecting portion 53 is formed on the outer periphery of the flow guide member 52, and the flow guide member 52 is connected to the heat dissipation member 51 through the connecting portion 53, and the flow guide member 52 is used to guide the air flow direction.

[0071] Among them, for the heat dissipation of the electrode assembly 2, that is, the fan is used to guide the air flow into the channel 101 through the flow guide member 52 to dissipate heat from the electrode assembly 2.

[0072] For the heat dissipation of the quartz lamp tube 1, that is, the heat dissipation member 51 is used for heat dissipation, and a connecting portion 53 for fixing the heat dissipation member 51 is installed on the flow guide member 52.

[0073] Regarding the structure of the flow guide member 52, specifically, the flow guide member 52 includes:

[0074] An annular ring portion 521; and a flared portion 522, the flared portion 522 is connected to the ring portion 521, and the flared portion 522 can guide the air flow to converge towards the ring portion 521, so that the air flow can pass through the channel 101 in sufficient quantity to promote the heat dissipation effect.

[0075] In addition, a plurality of holes 5221 are formed in the flared portion 522. When the air flow passes through the flared portion 522, a small amount of the air flow will pass through the holes 5221 and be dispersed on the outer periphery of the quartz lamp tube 1, so as to be able to cool and dissipate the heat of the quartz lamp tube 1.

[0076] According to the disclosure and teaching of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
