DETAILED DESCRIPTION

[0044] The core of the utility model is to provide an ultraviolet germicidal lamp device, which can use the sterilization function during foot bathing, improve user experience, kill germs and reduce the risk of cross infection;

[0045] Another core of the utility model is to provide a foot bath having the above-mentioned ultraviolet germicidal lamp device.

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] The embodiment of the utility model provides an ultraviolet sterilization lamp device, which can be used in a foot bath and connected to the circulating water system of the foot bath, so that the foot bath water in the foot bath can flow through the ultraviolet sterilization lamp device, and the ultraviolet sterilization lamp device is used for sterilization. Under the circulation of the circulating water system, the ultraviolet sterilization lamp device can be kept to continuously sterilize the foot bath water. Since only the foot bath water flowing through is sterilized, it is not necessary to irradiate the barrel of the foot bath with ultraviolet light, which can avoid harm to the user. Since it is harmless to the user during the sterilization process, the foot bath water can be processed in real time, that is, the sterilization function can be used during the foot bath, which improves the user experience, kills germs at the same time, and reduces the risk of cross infection.

[0048] See also Figure 2 to Figure 4 The ultraviolet germicidal lamp device disclosed in the embodiment of the utility model includes a first germicidal lamp housing 411 , a second germicidal lamp housing 415 , a transparent lampshade 412 and an ultraviolet lamp assembly 413 .

[0049] The second germicidal lamp housing 415 is sealedly connected to the first germicidal lamp housing 411, and a lamp housing cavity is formed between the first germicidal lamp housing 411 and the second germicidal lamp housing 415. In order to ensure that the components in the lamp housing cavity can be disassembled, the first germicidal lamp housing 411 and the second germicidal lamp housing 415 are connected in a detachable manner, for example, the two can be assembled by fasteners or buckles.

[0050] The transparent lampshade 412 is arranged in the lamp housing cavity. The transparent lampshade 412 is made of a light-transmitting material so as to at least allow ultraviolet rays to penetrate. After the transparent lampshade 412 is installed in the lamp housing cavity, the lamp housing cavity is divided into a sealed water inlet and outlet cavity and an ultraviolet lamp installation space. The water inlet and outlet cavity needs to be sealed and separated from the ultraviolet lamp installation space because the foot bath water needs to pass through it, so as to prevent the foot bath water from entering the ultraviolet lamp installation space, causing the ultraviolet lamp assembly 413 in the ultraviolet lamp installation space to be disconnected, thereby affecting normal use.

[0051] The water inlet and outlet cavity has at least one water inlet interface 4113 and at least one water outlet interface. It should be noted that when the ultraviolet germicidal lamp device is connected to the circulating water system of the foot bath, the water inlet interface 4113 can be connected to the circulating water system so that the foot bath water circulating in the circulating water system can flow into the water inlet and outlet cavity. The water outlet interface can be directly connected to the barrel of the foot bath, or it can be connected to the circulating water system so that the ultraviolet germicidal lamp device is connected in series to the water circulation system. The ultraviolet germicidal lamp device can be connected to the uppermost stream of the circulating water system, or it can be connected to the lowermost stream of the circulating water system, or it can be connected to the midstream of the circulating water system.

[0052] The ultraviolet lamp assembly 413 is disposed in the ultraviolet lamp installation space and is used to irradiate ultraviolet light in the direction of the transparent lampshade 412. The ultraviolet lamp assembly 413 can usually protect the circuit board and the ultraviolet lamp disposed on the circuit board. During installation, the ultraviolet lamp needs to be directed toward the transparent lampshade 412 so that ultraviolet light can be emitted in the direction of the transparent lampshade 412.

[0053] The ultraviolet lamp assembly 413 may include a circuit board and ultraviolet germicidal lamp beads disposed on the circuit board, wherein the ultraviolet germicidal lamp beads include at least two-band ultraviolet light lamp beads, the two-band ultraviolet light is respectively ultraviolet light of two bands of UVA and UVC. Ultraviolet germicidal lamp beads have advantages over traditional germicidal lamp tubes such as long life and no risk of water leakage.

[0054] In this embodiment, the ultraviolet germicidal lamp device can be used as a separate assembly, which can be applied to different types of water-filled footbath buckets (i.e., footbaths). The ultraviolet germicidal lamp device has good compatibility, so that the ultraviolet germicidal function can be added to the footbath without ultraviolet germicidal function, which can greatly reduce the cost. The ultraviolet germicidal lamp device sterilizes the circulating hot water for foot washing, which increases the efficiency of sterilization. In addition, the ultraviolet germicidal lamp device has good effects on the purification, sterilization, disinfection and skin disease treatment of footbath water.

[0055] Since the circulating heated water is sterilized during the foot washing process, the sterilization effect is related to the irradiation amount, and the foot bath water that is constantly circulating will be constantly irradiated, thereby increasing the sterilization rate of bacteria and fungi. The ultraviolet sterilization lamp device can be placed at the bottom of the barrel, and does not directly irradiate the user, which is harmless to the user. Moreover, the utility model can perform sterilization during the foot washing process, and there is no need to sterilize the barrel body before or after foot washing, thereby improving the user experience.

[0056] like Figure 3 and Figure 4 As shown, the ultraviolet lamp assembly 413 can be fixed on the transparent lampshade 412 or the second germicidal lamp housing 415 by fasteners, or the fixing method without fasteners can be adopted to improve the installation efficiency. For example, in this embodiment, an ultraviolet lamp support rib 4152 can be set on the second germicidal lamp housing 415, and the ultraviolet lamp assembly 413 is pressed by the ultraviolet lamp support rib 4152 on the side surface of the transparent lampshade 412 that is opposite to the water inlet and outlet chamber. That is, in this embodiment, after the first germicidal lamp housing 411 and the second germicidal lamp housing 415 are fixed, the ultraviolet lamp support rib 4152 will press the ultraviolet lamp assembly 413 on the transparent lampshade 412. During installation, it is only necessary to place the ultraviolet lamp assembly 413 and the transparent lampshade 412 at the corresponding positions between the first germicidal lamp housing 411 and the second germicidal lamp housing 415, and then fasten the first germicidal lamp housing 411 and the second germicidal lamp housing 415, and the ultraviolet lamp assembly 413 can be fixed.

[0057] In this embodiment, the ultraviolet lamp support rib 4152 can be an annular structure, and the second germicidal lamp housing 415 has an annular outer wall arranged concentrically with the ultraviolet lamp support rib 4152, and an annular groove 4153 is formed between the annular outer wall and the ultraviolet lamp support rib 4152. It should be noted that the ultraviolet lamp support rib 4152 can also be a discontinuous structure, that is, it is composed of a plurality of support blocks arranged in a ring shape. A plurality of protrusions can be provided on the ultraviolet lamp support rib 4152, and the ultraviolet lamp assembly 413 is abutted by the protrusions. That is, in this embodiment, the ultraviolet lamp support rib 4152 has a plurality of ( Figure 3 The scheme shown has two protrusions, which contact the ultraviolet lamp assembly 413 through the protrusions. There is no need for the ultraviolet lamp supporting rib 4152 to be completely in contact with the ultraviolet lamp assembly 413 on one side thereof. This can reduce the processing accuracy of the ultraviolet lamp supporting rib 4152, reduce material usage, and reduce manufacturing costs.

[0058] The first germicidal lamp housing 411 presses one end of the transparent lampshade 412 into the annular groove 4153. The inner ring side wall and the outer ring side wall of the annular groove 4153 can form a limit for the first germicidal lamp housing 411 and the transparent lampshade 412, so as to facilitate the docking of the first germicidal lamp housing 411 and the transparent lampshade 412 with the second germicidal lamp housing 415. At the same time, after installation, relative movement between the three (the first germicidal lamp housing 411, the second germicidal lamp housing 415 and the transparent lampshade 412) can be avoided, thereby improving the reliability of installation. In addition, the formation of the annular groove 4153 is also helpful for sealing.

[0059] In order to facilitate the installation of the transparent lampshade 412, the transparent lampshade 412 has a lampshade body 4121 and a fixed pressing edge 4122, so that the transparent lampshade 412 has a flange-like structure. The lampshade body 4121 is a slot structure with one side open, the bottom of the slot of the lampshade body 4121 faces the water inlet and outlet cavity, and the open side of the lampshade body 4121 is connected to the fixed pressing edge 4122, and the fixed pressing edge 4122 is located on the outside of the lampshade body 4121.

[0060] It should be noted that the width of the fixed pressing edge 4122 should be smaller than the width of the annular groove 4153, so that the fixed pressing edge 4122 can be embedded in the annular groove, and the first germicidal lamp housing 411 is crimped on the fixed pressing edge 4122. That is, the portion of the first germicidal lamp housing 411 extending into the annular groove 4153 can be directly or indirectly crimped on the fixed pressing edge 4122 to press the fixed pressing edge 4122 against the bottom wall of the annular groove 4153.

[0061] Furthermore, the first germicidal lamp housing 411 includes a germicidal lamp housing body and an embedded pressing edge. The germicidal lamp housing body is a slot structure with an opening on one side, and the open side of the germicidal lamp housing body is connected to the embedded pressing edge, and the embedded pressing edge is located on the outside of the germicidal lamp housing body. The embedded pressing edge at least includes a first side wall, and a sealing ring 414 is provided between the first side wall and the fixed pressing edge 4122. The sealing ring 414 can be a rubber sealing ring or a silicone sealing ring, as long as the sealing ring 414 has a certain elasticity and can be compressed. As the first germicidal lamp housing 411 and the second germicidal lamp housing 415 are tightened, the sealing ring 414 is gradually compressed and elastically deformed to form a reliable seal.

[0062] The area surrounded by the ultraviolet lamp support ribs 4152 is a hollow structure, which is more conducive to the ultraviolet lamp assembly 413 to dissipate heat through the hollow structure. In addition, the hollow structure is provided so that even if the sealing ring 414 fails, causing the footbath water in the water cavity to leak at the sealing ring 414, it will not affect the ultraviolet lamp assembly 413. Since the ultraviolet lamp assembly 413 is lifted up by the convex points on the ultraviolet lamp support ribs 4152, a gap is formed between the ultraviolet lamp support ribs 4152 and the ultraviolet lamp support ribs 4152 at the non-convex point position, and the leaked footbath water will be discharged through the gap and the hollow structure, and will not soak the ultraviolet lamp assembly 413.

[0063] In a specific embodiment of the utility model, the embedded pressing edge may also include a second side wall, the second side wall is connected to the outer side of the first side wall, and the second side wall is embedded in the annular groove and is located between the fixed pressing edge 4122 and the annular outer wall. In this embodiment, the first side wall and the second side wall can be designed to be perpendicular to each other. In this way, the sealing ring 414 can be pressed tightly in the space surrounded by the first side wall and the second side wall of the embedded pressing edge and the outer side wall of the fixed pressing edge 4122 and the lampshade body 4121, so that the upper and lower surfaces and the inner and outer side walls of the sealing ring 414 are in contact with the first germicidal lamp housing 411 and the transparent lampshade 412, further improving the sealing effect.

[0064] It should be noted that the cross-sections of the lampshade body 4121, the annular groove 4153 and the germicidal lamp housing body are all circular, and of course they can also be other shapes, and the present invention does not limit their shapes.

[0065] In a specific embodiment of the utility model, a first fixing portion 4114 is provided on the first germicidal lamp housing 411. The first fixing portion 4114 can be arranged on the outer side wall of the germicidal lamp housing body. The first fixing portion 4114 can be designed as an integrated structure with the germicidal lamp housing body and integrally formed by an injection molding process. The number of the first fixing portions 4114 can be designed according to the fastening requirements. In this embodiment, there are multiple first fixing portions 4114, for example, 2-5.

Figure 3 Two are shown in the scheme.

[0068] The third fixing part 4115 is used to be fixed with the fourth fixing part 120 on the barrel body 100 of the foot bath through a fastener. The number of the fourth fixing part 120 should be the same as the third fixing part 4115, and they should correspond one to one. When the first germicidal lamp housing 411 and the second germicidal lamp housing 415 are fastened, the third fixing part 4115 and the fourth fixing part 120 need to be matched one to one first, and then the third fixing part 4115 and the fourth fixing part 120 are fixed by fasteners.

The fastener passes through the light hole and is tightened on the threaded hole, so that the third fixing part 4115 and the fourth fixing part 120 can be fastened, and then the ultraviolet germicidal lamp device can be fixed on the barrel body 100 of the foot bath.

[0069] Furthermore, the water inlet interface 4113 and the water outlet interface are both arranged on the first sterilization lamp housing 411. As long as the water inlet interface 4113 and the water outlet interface can be connected to the water inlet and outlet chambers, the utility model does not limit their arrangement positions. The water outlet interface at least includes a first water outlet interface 4111 and a second water outlet interface 4112. In this embodiment, multiple water outlet interfaces are provided, and multiple water outlet points can be arranged on the barrel body 100 to improve the mixing effect of the foot bath water after sterilization.
