[0036] In actual use, a certain amount of water is temporarily stored in the heating mechanism and the water spraying mechanism. In the standby state, the water in the heating mechanism or the water spraying mechanism is prone to bacterial growth, thereby affecting the use safety and user experience.

[0037] To solve the problem of bacterial growth due to temporary storage of water, the related mechanisms of the dry-wet paper machine are designed and improved as follows.

[0038] In embodiment one, for the heating mechanism, after heating is completed, the water inside the heating mechanism in the standby state is prone to bacterial growth. To solve the problem of bacterial growth due to storage of water inside the heating mechanism, the heating mechanism is improved and designed as follows.

[0039] As shown in Figures 3-6 The embodiment provides a heating mechanism 1, which includes:

[0040] A heating container 11 is formed with a heating cavity inside, which is configured to temporarily store water to be heated. The heating container 11 is provided with a water inlet connection part and a water outlet connection part, which respectively communicate with the heating cavity.

[0041] An electric heating element 12 is arranged on the heating container 11 and is configured to heat the water in the heating container 11.

[0042] The heating container 11 is further provided with a first sterilization irradiation port, which is sealed and covered with a first quartz plate 13. A first ultraviolet LED lamp 14 is arranged outside the first quartz plate 13. The first ultraviolet LED lamp 14 is configured to irradiate ultraviolet light into the heating container 11 through the first quartz plate 13.

[0043] Specifically, for the heating container 11, a heating cavity is formed inside, and the water in the heating cavity can be heated under the action of the electric heating element 12, thereby meeting the requirements of use.

[0044] In the state of not being used, the water in the heating container 11 is in a static state, and with the extension of time, the water in the heating container 11 is easy to breed bacteria. By arranging the first sterilization irradiation port on the heating container 11, and sealing and shielding the first sterilization irradiation port by the first quartz plate 13, the ultraviolet irradiation generated by the first ultraviolet LED lamp 14 arranged outside the first quartz plate 13 can irradiate into the heating container 11, and the water stored in the heating container 11 is sterilized and treated by the ultraviolet, thereby reducing the continuous breeding of bacteria in the heating container 11.

[0045] Further, the heating container 11 comprises a heating cylinder 111, a first end cover 112 and a second end cover 113, the heating cylinder 111 is connected between the first end cover 112 and the second end cover 113, and a heating cavity is formed between the heating cylinder 111, the first end cover 112 and the second end cover 113.

[0046] The first quartz plate 13 is clamped between the heating cylinder 111 and the second end cover 113, and the port of the heating cylinder 111 adjacent to the second end cover 113 forms the first sterilization irradiation port; the first ultraviolet LED lamp 14 is located between the second end cover 113 and the first quartz plate 13.

[0047] Specifically, for the heating container 11, a split structure is adopted to facilitate assembly, and the heating cylinder 111 is between the first end cover 112 and the second end cover 113. The port of the heating cylinder 111 adjacent to the second end cover 113 serves as the first sterilization irradiation port, so that a hole does not need to be opened on the cylinder wall of the heating cylinder 111, thereby reducing the processing difficulty.

[0048] The first quartz plate 13 will be sealed at the port of the heating cylinder 111, and the first ultraviolet LED lamp 14 will be installed between the first quartz plate 13 and the second end cover 113, so that the first ultraviolet LED lamp 14 can be conveniently built-in in the heating container 11 to facilitate assembly.

[0049] Further, a stepped surface 114 is formed in the first sterilization irradiation port, the first quartz plate 13 abuts against the stepped surface 114, a sealing ring is arranged between the first quartz plate 13 and the stepped surface 114, and the second end cover 113 abuts against the first quartz plate 13 and presses the first quartz plate 13 on the sealing ring.

[0050] Specifically, in order to improve the installation sealing performance of the first quartz plate 13, the stepped surface 114 is formed at the port of the heating cylinder 111 to press the sealing ring between the first quartz plate 13 and the stepped surface 114, and the sealing ring can effectively enhance the connection sealing performance between the first quartz plate 13 and the stepped surface 114.

[0051] Further, the second end cover 113 is provided with an annular rib 115, which surrounds a mounting area where the first UV LED lamp 14 is located, and the annular rib 115 abuts against the first quartz plate 13.

[0052] Specifically, the annular rib 115 formed on the second end cover 113 can exert sufficient pressure on the first quartz plate 13 to ensure that the first quartz plate 13 presses the sealing ring against the stepped surface 114. Meanwhile, the annular rib 115 surrounding the mounting area can also pre-mount the first UV LED lamp 14.

[0053] Further, the heating cylinder 111 is made of a heat-conducting material, and the outer wall of the heating cylinder 111 is provided with a heat-conducting mounting surface 116, on which the electric heating element 12 is arranged.

[0054] Specifically, the heating cylinder 111 is made of a heat-conducting material, such as stainless steel or aluminum, etc. The outer surface of the heating cylinder 111 is formed with a heat-conducting mounting surface 116, which is a plane. In this way, the heat-conducting connection area between the electric heating element 12 and the heating cylinder 111 can be effectively increased to improve the heating efficiency.

[0055] The electric heating element 12 can be a PTC heating sheet or an electric heating plate, etc.

[0056] To facilitate the connection of the waterway, the first end cover 112 can be provided with the water inlet connecting portion. The first end cover 112 can be connected with the water pump 3 through the water inlet connecting portion to meet the requirement of delivering water into the heating container 11. The water inlet connecting portion can be a water inlet connector, etc., which is not limited here.

[0057] In addition, to meet the requirement of outputting the heated water outside the heating container 11, the heating cylinder 111 is further provided with an extension 117 at the end adjacent to the second end cover 113, and the extension 117 protrudes from the outer wall of the heating cylinder 111.

[0058] The extension 117 is provided with the water outlet connecting portion.

[0059] Specifically, the extension 117 of the heating cylinder 111 forms the water outlet connecting portion, which can meet the requirement of outputting the water in the heating cavity outside.

[0060] The extension 117 is further provided with a connecting water groove 119, which communicates the water outlet connecting portion and the heating cavity.

[0061] The second end cover 113 also covers the outside of the connecting water groove 119.

[0062] Specifically, in order to make the water in the heating cylinder 111 flow to the water outlet connection part after being heated and output outward, a connecting water tank 119 can be arranged between the water outlet connection part and the port of the heating cylinder 111, so that the water in the heating cylinder 111 flows to the water outlet connection part through the connecting water tank 119. For example, the water outlet connection part can be a through hole 118, the connecting water tank 119 communicates the through hole 118 with the port of the heating cylinder 111, and the first quartz plate 13 seals the through hole 118, the connecting water tank 119 and the port of the heating cylinder 111.

[0063] In addition, in order to perform heat preservation treatment on the heating container 11, the heating container 11 is wrapped with a heat preservation layer 15.

[0064] Based on the heating mechanism 1 in the above embodiment, the dry and wet paper machine provided by the application connects the above heating mechanism 1 between the water spraying mechanism 2 and the water pump 3.

[0065] By arranging the first sterilization irradiation port on the heating container 11, the first sterilization irradiation port can be sealed and covered by the first quartz plate 13, and then the first ultraviolet LED lamp 14 can be arranged outside the first quartz plate 13. The first ultraviolet LED lamp 14 irradiates ultraviolet rays into the heating container 11, so that in actual use, the water in the heating container 11 can be affected by the ultraviolet rays generated by the first ultraviolet LED lamp 14 to reduce the generation of bacteria, thereby improving the safety and experience of users.

[0066] In the second embodiment, for the water spraying mechanism 2, after completing the water spraying operation, the water in the water spraying mechanism 2 in the standby state is easy to breed bacteria. In order to solve the problem of breeding bacteria in the water in the water spraying mechanism 2, the water spraying mechanism 2 is improved and designed as follows.

[0067] As shown in Figures 7-9 The heating mechanism 1 provided by the embodiment includes:

[0068] The water spraying seat 21 is in a strip structure, and is provided with a water supply channel 211 and a plurality of water outlet channels 212. The water spraying seat 21 is provided with a mounting socket 213 communicating with the water supply channel 211 at the end thereof. A plurality of water spraying holes 214 are arranged on the front side of the water spraying seat 21 and communicate with the corresponding water outlet channels 212. The plurality of water outlet channels 212 respectively communicate with the water supply channel 211.

[0069] The connecting pipe 22 is provided with a plurality of connecting holes 221 on the pipe wall thereof. The connecting pipe 22 is sealingly inserted into the mounting socket 213 and extends into the water supply channel 211. The connecting holes 221 communicate with the corresponding water outlet channels 212.

[0070] A second ultraviolet LED lamp 23 is arranged at the end of the connecting pipe 22 and configured to irradiate ultraviolet light into the connecting pipe 22.

[0071] Specifically, the connecting pipe 22 is inserted into the water supply channel 211 of the water spraying seat 21, and the connecting pipe 22 can be used to transport water. After the water in the connecting pipe 22 is transported into the water spraying seat 21, the water in the connecting pipe 22 flows into the corresponding water outlet channel 212 through the connecting hole 221 to meet the requirement of water outlet.

[0072] In the state of not being used, the water in the connecting pipe 22 is in a static state, and with the extension of time, the water in the connecting pipe 22 is easy to breed bacteria. By arranging the second ultraviolet LED lamp 23 at the end of the connecting pipe 22, the second ultraviolet LED lamp 23 generates ultraviolet light irradiation into the connecting pipe 22, and the water stored in the connecting pipe 22 is sterilized by the ultraviolet light, thereby reducing the continuous breeding of bacteria in the connecting pipe 22.

[0073] The pipe diameter of the connecting pipe 22 is larger than that of the water outlet channel 212, so the water storage capacity in the connecting pipe 22 will be much larger than that of the water outlet channel 212. In the case of effectively inhibiting the breeding of bacteria in the connecting pipe 22, the overall number of bacteria can be effectively inhibited.

[0074] Preferably, the outer wall of the connecting pipe 22 is further provided with a reflective layer, which is configured to reflect ultraviolet light towards the connecting hole 221.

[0075] Specifically, the reflective layer arranged on the connecting pipe 22 can emit ultraviolet light into the water outlet channel 212, thereby further inhibiting the breeding of bacteria in the water outlet channel 212 to a certain extent.

[0076] Further, the connecting pipe 22 is provided with a positioning portion 222, and the water spraying seat 21 is provided with a positioning matching portion; the positioning portion 222 and the positioning matching portion are connected together.

[0077] Specifically, since the connecting hole 221 arranged on the connecting pipe 22 needs to communicate with the corresponding water outlet channel 212, after the connecting pipe 22 is inserted into the water inlet channel, the connecting hole 221 of the connecting pipe 22 needs to be adjusted to be aligned with the water outlet channel 212. In order to improve the assembly convenience, by positioning the positioning portion 222 and the positioning matching portion, the installation posture of the connecting pipe 22 can be positioned so that the connecting hole 221 can be aligned with the water outlet channel 212.

[0078] The positioning part 222 is a positioning notch formed at the pipe opening of the connecting pipe 22, and the positioning matching part is a positioning protrusion formed in the water supply channel 211, which is clamped in the positioning notch. Alternatively, the positioning part 222 is a positioning block formed on the outer pipe wall of the connecting pipe 22, and the positioning matching part is a positioning clamping groove formed on the water spraying seat 21, and the positioning block is clamped in the positioning clamping groove.

[0079] In addition, in order to improve the effect of water spraying, the water spraying mechanism 2 further comprises a spray head 25 which is detachably arranged on the water spraying seat 21 and covers the water spraying hole 214.

[0080] Specifically, the water output from the water spraying hole 214 can be treated by the spray head 25 to achieve a spraying effect. The specific structure of the spray head 25 can adopt the structure of a conventional spray head, which is not limited and described here.

[0081] Further, for the second ultraviolet LED lamp 23, it can be installed at any end of the connecting pipe 22. For example, the second ultraviolet LED lamp 23 is arranged outside the water spraying seat 21, and the second ultraviolet LED lamp 23 is located outside the outer pipe opening of the connecting pipe 22.

[0082] Alternatively, the water spraying seat 21 is provided with a second sterilization irradiation opening, which is arranged at the end of the water supply channel 211, and the second sterilization irradiation opening is in communication with the water supply channel 211. The second sterilization irradiation opening is sealingly provided with a second quartz plate 24; the second ultraviolet LED lamp 23 is arranged outside the second quartz plate 24, and the second ultraviolet LED lamp 23 is located outside the inner pipe opening of the connecting pipe 22.

[0083] Based on the water spraying mechanism 2 in the above embodiment, the dry and wet paper machine provided by the application directly or indirectly connects the water spraying mechanism 2 and the water pump 3 to realize sterilization and water spraying.

[0084] By arranging the connecting pipe 22 in the water supply channel 211 of the water spraying seat 21, the connecting pipe 22 is used to meet the requirement of supplying water to the water spraying hole 214, and the end of the connecting pipe 22 is further provided with the second ultraviolet LED lamp 23. The second ultraviolet LED lamp 23 irradiates ultraviolet rays into the connecting pipe 22, so that in actual use, the water in the connecting pipe 22 can be reduced by the ultraviolet irradiation of the second ultraviolet LED lamp 23. Bacteria are generated, thereby improving the user safety and experience.

[0085] Based on the above embodiments one and two, the technical problem of easy breeding of bacteria in the internal water storage of the heating mechanism 1 and the water spraying mechanism 2 is solved by simultaneously improving the design of the heating mechanism 1 and the water spraying mechanism 2.

[0090] Wherein, the water pump 3, the heating container 11 and the connecting pipe 22 are sequentially connected.

[0091] Specifically, the heating container 11 in the heating mechanism 1 can be irradiated by the first ultraviolet LED lamp 14 to achieve sterilization and bacteriostatic treatment during use, and similarly, the connecting pipe 22 in the water spraying mechanism 2 can be irradiated by the second ultraviolet LED lamp 23 to achieve sterilization and bacteriostatic treatment. Ultraviolet rays are used to sterilize the stored water, thereby reducing the continuous breeding of bacteria in the stored water.

[0092] Further, the heating container 11 comprises a heating cylinder 111, a first end cover 112 and a second end cover 113, the heating cylinder 111 is connected between the first end cover 112 and the second end cover 113, and a heating cavity is formed between the heating cylinder 111, the first end cover 112 and the second end cover 113;

[0093] The heating cylinder 111 is further provided with an extension 117 at the end adjacent to the second end cover 113, and the extension 117 protrudes from the outer wall of the heating cylinder 111;

[0094] The extension 117 is provided with a through hole 118, and the surface of the extension 117 opposite to the second end cover 113 is further provided with a connecting water groove 119, and the connecting water groove 119 is connected between the through hole 118 and the port of the heating cylinder 111;

[0095] The first quartz plate 13 is clamped between the heating cylinder 111 and the second end cover 113, and the first quartz plate 13 further seals and covers the through hole 118 and the connecting water groove 119;

[0096] The connecting pipe 22 is sealingly inserted into the through hole 118, and the connecting pipe 22 communicates with the heating cavity through the connecting water groove 119; the first ultraviolet LED lamp 14 and the second ultraviolet LED lamp 23 are arranged between the first quartz plate 13 and the second end cover 113;

[0097] The first ultraviolet LED lamp 14 is arranged at the port of the heating cylinder 111 and is configured to irradiate ultraviolet rays into the heating cylinder 111 through the first quartz plate 13;

[0098] The second ultraviolet LED lamp 23 is arranged at the through hole 118 and is configured to irradiate ultraviolet rays into the connecting pipe 22 through the first quartz plate 13 and the through hole 118.

[0099] Specifically, since the water output by the heating mechanism 1 is delivered into the water spraying seat 21 through the connecting pipe 22 and sprayed out of the water spraying hole 214, in order to facilitate the centralized installation of the first ultraviolet LED lamp 14 and the second ultraviolet LED lamp 23, the first ultraviolet LED lamp 14 and the second ultraviolet LED lamp 23 can be installed on the second end cover 113 of the heating container 11.

[0100] Since the end of the connecting pipe 22 is inserted into the through hole 118 of the extension 117, and the through hole 118 is further sealed and covered by the first quartz plate 13. In this way, the second ultraviolet LED lamp 23 can irradiate ultraviolet rays through the first quartz plate 13 and into the connecting pipe 22 through the through hole 118.

[0101] And because the first ultraviolet LED lamp 14 and the second ultraviolet LED lamp 23 are centrally installed between the second end cover 113 and the first quartz plate 13, on the one hand, it is convenient to centrally assemble, and on the other hand, it is also convenient for the second ultraviolet LED lamp 23 to irradiate the inside of the connecting pipe 22 from the end of the connecting pipe 22.
