Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an ultraviolet sterilization and humidification mechanism and a dry and wet paper machine. Background Technology

[0002] Paper towels are a common daily necessity, available in both sheet-fed and roll-fed forms. As living standards improve, the demand for humidifying paper towels is increasing, leading to the widespread adoption of corresponding devices. Chinese Patent Publication No. CN115886620A discloses a wet / dry paper machine and its control method, which humidifies paper towels by spraying water. The humidification mechanism includes a water pump, a heating channel, and an electric heating element.

However, in actual use, a certain amount of water remains in the nozzle during standby. This water is prone to bacterial growth, potentially leading to excessive bacteria levels in the sprayed water, resulting in poor user safety and experience. Therefore, designing a technology to improve user safety and experience is the technical problem this invention aims to solve. Utility Model Content

[0043] One embodiment of this utility model provides a wet and dry paper machine, including a housing, a humidification mechanism and a water tank disposed within the housing. The humidification mechanism is equipped with a heating mechanism and a water spraying mechanism. The heating mechanism draws water from the water tank into the heating mechanism for heating via a water pump, and the heated water is then sprayed outwards through the water spraying mechanism. For specific structural configurations, please refer to existing wet and dry paper machines (CN 115886620 A), which will not be limited or described in detail here.

[0044] In actual use, both the heating mechanism and the water spraying mechanism will temporarily store a certain amount of water. In standby mode, the water in the heating mechanism or the water spraying mechanism is prone to bacterial growth, which will affect the safety and user experience.

[0045] To address the issue of bacterial growth due to temporarily stored water, the following structural design and improvements were made to the relevant mechanisms of the wet and dry paper machine.

[0046] In Example 1, for the heating mechanism, because bacteria can easily grow in the water inside the heating mechanism when it is in standby mode after heating is completed, the heating mechanism is improved as follows to solve the problem of bacteria growing in the water inside the heating mechanism.

[0047] like Figures 3-6 As shown, this embodiment provides a heating mechanism 1, including:

[0048] A heating container 11 has a heating cavity formed inside it. The heating cavity is configured to temporarily store water to be heated. The heating container 11 is provided with an inlet connection and an outlet connection, which are respectively connected to the heating cavity.

[0049] An electric heating element 12 is disposed on the heating container 11 and configured to heat the water in the heating container 11;

[0050] The heating container 11 is further provided with a first sterilization irradiation port, and a first quartz plate 13 is sealed and covered on the first sterilization irradiation port. A first ultraviolet LED lamp 14 is provided 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.

[0051] Specifically, for the heating container 11, a heating cavity is formed inside. The water in the heating cavity can be heated by the electric heating element 12 to meet the requirements of use.

[0052] When not in use, the water in the heating container 11 remains stagnant, and bacteria can easily grow in it over time. By providing a first sterilization irradiation port on the heating container 11 and sealing it with a first quartz plate 13, ultraviolet light generated by a first ultraviolet LED lamp 14 arranged outside the first quartz plate 13 can be used to irradiate the water stored in the heating container 11. This ultraviolet light sterilizes the water, thereby reducing the continuous growth of bacteria inside the heating container 11.

[0053] Furthermore, the heating container 11 includes a heating cylinder 111, a first end cap 112 and a second end cap 113, the heating cylinder 111 is connected between the first end cap 112 and the second end cap 113, and a heating cavity is formed between the heating cylinder 111, the first end cap 112 and the second end cap 113;

[0054] The first quartz plate 13 is sandwiched between the heating cylinder 111 and the second end cap 113, and the heating cylinder 111 forms the first sterilization irradiation port adjacent to the port of the second end cap 113; the first ultraviolet LED lamp 14 is located between the second end cap 113 and the first quartz plate 13.

[0055] Specifically, the heating container 11 adopts a split structure for easy assembly, with the heating cylinder 111 located between the first end cap 112 and the second end cap 113. The port of the heating cylinder 111 adjacent to the second end cap 113 serves as the first sterilization irradiation port, thus eliminating the need to drill holes in the cylinder wall of the heating cylinder 111 and reducing the difficulty of processing.

[0056] 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 cap 113. In this way, the first ultraviolet LED lamp 14 can be conveniently built into the heating container 11 for easy assembly.

[0057] Furthermore, 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 provided between the first quartz plate 13 and the stepped surface 114, and the second end cap 113 abuts against the first quartz plate 13 and presses the first quartz plate 13 tightly against the sealing ring.

[0058] Specifically, in order to improve the installation sealing of the first quartz plate 13, a 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. The sealing ring can effectively enhance the connection sealing between the first quartz plate 13 and the stepped surface 114.

[0059] Furthermore, the second end cap 113 is also provided with an annular rib 115, which surrounds and forms an installation area. The first ultraviolet LED lamp 14 is located in the installation area, and the annular rib 115 abuts against the first quartz plate 13.

[0060] Specifically, the annular rib 115 formed on the second end cap 113 can apply sufficient pressure to the first quartz plate 13 to ensure that the first quartz plate 13 presses the sealing ring tightly onto the stepped surface 114. At the same time, the mounting area formed around the annular rib 115 can also be pre-installed with the first ultraviolet LED lamp 14.

[0061] Furthermore, the heating cylinder 111 is made of a thermally conductive material, and the outer wall of the heating cylinder 111 is provided with a thermally conductive mounting surface 116, and the electric heating element 12 is disposed on the thermally conductive mounting surface 116.

[0062] Specifically, the heating cylinder 111 is made of a thermally conductive material, such as stainless steel or aluminum. The outer surface of the heating cylinder 111 has a thermally conductive mounting surface 116, which is flat. This effectively increases the thermally conductive connection area between the electric heating element 12 and the heating cylinder 111, thereby improving heating efficiency.

[0063] The electric heating element 12 can be a conventional electric heating element such as a PTC heating element or an electric heating plate.

[0064] To facilitate water connection, a water inlet connection can be provided on the first end cap 112. The first end cap 112 can be connected to the water pump 3 through the water inlet connection to meet the requirement of supplying water to the heating container 11. The water inlet connection can be a physical entity such as a water inlet connector, and is not limited thereto.

[0065] In addition, in order to meet the requirement of the heating container 11 to output heated water, the heating cylinder 111 is provided with an extension 117 at the end adjacent to the second end cap 113, and the extension 117 protrudes from the outer wall of the heating cylinder 111.

[0066] The extension 117 is provided with the water outlet connection part.

[0067] Specifically, the extension 117 of the heating cylinder 111 forms a water outlet connection, which can meet the requirement of water being output from the heating chamber.

[0068] The extension 117 is also provided with a connecting water tank 119, which connects the water outlet connection and the heating cavity.

[0069] The second end cap 113 also covers the outside of the connecting water tank 119.

[0070] Specifically, in order for the water in the heating cylinder 111 to be heated and then flow to the outlet connection for output, a connecting water tank 119 can be provided between the outlet connection and the port of the heating cylinder 111. In this way, the water in the heating cylinder 111 flows to the outlet connection via the connecting water tank 119. For example, the outlet connection can be a through hole 118, and the connecting water tank 119 connects the through hole 118 to the port of the heating cylinder 111. The first quartz plate 13 covers and seals the through hole 118, the connecting water tank 119, and the port of the heating cylinder 111.

[0071] In addition, in order to keep the heating container 11 warm, the heating container 11 is wrapped with an insulation layer 15.

[0072] Based on the heating mechanism 1 in the above embodiments, the dry and wet paper machine provided in this application connects the heating mechanism 1 between the water spraying mechanism 2 and the water pump 3.

[0073] By providing a first sterilization irradiation port on the heating container 11, which can be sealed and covered by a first quartz plate 13, a first ultraviolet LED lamp 14 can be installed on the outside of the first quartz plate 13. The first ultraviolet LED lamp 14 irradiates ultraviolet light into the heating container 11. In actual use, the water in the heating container 11 can reduce the growth of bacteria due to the ultraviolet light irradiation generated by the first ultraviolet LED lamp 14, thereby improving user safety and experience.

[0074] In Example 2, for the water spraying mechanism 2, after the water spraying operation is completed, bacteria easily grow in the water inside the water spraying mechanism 2 in the standby state. In order to solve the problem of bacteria growing in the water inside the water spraying mechanism 2, the following improved design is made to the water spraying mechanism 2.

[0075] like Figures 7-9 As shown, this embodiment provides a heating mechanism 1, including:

[0076] A water spray base 21 is strip-shaped and has a water supply channel 211 and multiple water outlet channels 212. The end of the water spray base 21 is provided with an installation socket 213 that connects to the water supply channel 211. Multiple water spray holes 214 are also provided on the front side of the water spray base 21, and the water spray holes 214 are connected to the corresponding water outlet channels 212. The multiple water outlet channels 212 are respectively connected to the water supply channel 211.

[0077] A connecting pipe 22 is provided with a plurality of connecting holes 221 on its wall. The connecting pipe 22 is sealed and inserted into the mounting socket 213 and extends into the water supply channel 211. The connecting holes 221 are connected to the corresponding water outlet channel 212.

[0078] The second ultraviolet LED lamp 23 is disposed at the end of the connecting tube 22 and configured to irradiate ultraviolet light into the connecting tube 22.

[0079] Specifically, a connecting pipe 22 is inserted into the water supply channel 211 of the spray base 21. The connecting pipe 22 can be used to transport water. After the water is transported into the spray base 21 through the connecting pipe 22, the water in the connecting pipe 22 will flow through the connecting hole 221 to the corresponding water outlet channel 212 to meet the requirements of water outlet.

[0080] When not in use, the water in the connecting pipe 22 remains stagnant, and bacteria can easily grow in it over time. By installing a second ultraviolet LED lamp 23 at the end of the connecting pipe 22, the ultraviolet light generated by the second ultraviolet LED lamp 23 is directed into the connecting pipe 22 to sterilize the water stored in the connecting pipe 22, thereby reducing the continuous growth of bacteria inside the connecting pipe 22.

[0081] The diameter of the connecting pipe 22 is larger than that of the outlet channel 212. Therefore, the amount of water stored in the connecting pipe 22 will be much greater than that stored in the outlet channel 212. In order to effectively inhibit the growth of bacteria in the water in the connecting pipe 22, the overall number of bacteria can be effectively reduced.

[0082] Preferably, the connecting tube 22 can be a quartz tube. For this purpose, the outer wall of the connecting tube 22 is also provided with a reflective layer, which is configured to reflect ultraviolet rays toward the connecting hole 221.

[0083] Specifically, the reflective layer on the connecting pipe 22 can emit ultraviolet rays into the water outlet channel 212, which can further inhibit the growth of bacteria in the water outlet channel 212 to a certain extent.

[0084] Furthermore, the connecting pipe 22 is provided with a positioning part 222, and the water spray base 21 is provided with a positioning mating part; the positioning part 222 is connected to the positioning mating part.

[0085] Specifically, since the connecting hole 221 on the connecting pipe 22 needs to communicate with the corresponding water outlet channel 212, after inserting the connecting pipe 22 into the water inlet channel, it is necessary to adjust the connecting hole 221 of the connecting pipe 22 to align with the water outlet channel 212. To improve assembly convenience, the positioning part 222 and the positioning mating part are mutually positioned and mated to position the installation posture of the connecting pipe 22, so that the connecting hole 221 can be aligned with the water outlet channel 212.

[0086] The positioning part 222 is a positioning notch formed at the opening of the connecting pipe 22, and the positioning mating part is a positioning protrusion formed in the water supply channel 211, the positioning protrusion being engaged in the positioning notch. Alternatively, the positioning part 222 is a positioning block formed on the outer wall of the connecting pipe 22, and the positioning mating part is a positioning groove formed on the spray seat 21, the positioning block being engaged in the positioning groove.

[0087] In addition, to improve the water spraying effect, the water spraying mechanism 2 also includes a nozzle 25, which is detachably mounted on the water spraying base 21 and covers the water spraying hole 214.

[0088] Specifically, the nozzle 25 allows water output from the spray hole 214 to be processed by the nozzle 25 to achieve a spray effect. The specific structure of the nozzle 25 can adopt the structure of a conventional spray head, and will not be limited or described in detail here.

[0089] Furthermore, the second ultraviolet LED lamp 23 can be installed at either end of the connecting pipe 22. For example, the second ultraviolet LED lamp 23 is arranged outside the water spray base 21, and the second ultraviolet LED lamp 23 is located outside the outer opening of the connecting pipe 22.

[0090] Alternatively, a second sterilization irradiation port is provided on the water spray base 21. The second sterilization irradiation port is arranged at the end of the water supply channel 211 and is connected to the water supply channel 211. A second quartz plate 24 is sealed on the second sterilization irradiation port. The second ultraviolet LED lamp 23 is arranged outside the second quartz plate 24 and is located outside the inner pipe opening of the connecting pipe 22.

[0091] Based on the water spraying mechanism 2 in the above embodiments, the dry and wet paper machine provided in this application connects the water spraying mechanism 2 and the water pump 3 directly or indirectly to achieve sterilization water spraying.

[0092] By providing a connecting pipe 22 in the water supply channel 211 of the spray base 21, the water supply requirements to the spray hole 214 are met. Furthermore, a second ultraviolet LED lamp 23 is provided at the end of the connecting pipe 22. The second ultraviolet LED lamp 23 irradiates ultraviolet light into the connecting pipe 22. In actual use, the water in the connecting pipe 22 is affected by the ultraviolet light generated by the second ultraviolet LED lamp 23, which can reduce the growth of bacteria, thereby improving the user's safety and experience.

[0093] Example 3: Based on Examples 1 and 2 above, and addressing the technical problem that bacteria can easily grow in the internal water of the heating mechanism 1 and the water spraying mechanism 2, the heating mechanism 1 and the water spraying mechanism 2 are simultaneously improved in design.

[0094] like Figures 1-7 and Figure 9 As shown, this embodiment provides an ultraviolet sterilization and humidification mechanism, including:

[0095] Water pump 3;

[0096] Heating mechanism 1 includes a heating container 11, an electric heating element 12, and a first ultraviolet LED lamp 14. A heating cavity is formed inside the heating container 11, and the electric heating element 12 is disposed on the heating container 11. The heating container 11 is also provided with a first sterilization irradiation port, and a first quartz plate 13 is sealed and covered on the first sterilization irradiation port. The first ultraviolet LED lamp 14 is disposed outside the first quartz plate 13.

[0097] A water spray mechanism 2 includes a water spray base 21, a connecting pipe 22, and a second ultraviolet LED lamp 23. The water spray base 21 has a water supply channel 211 and multiple water outlet channels 212. The end of the water spray base 21 has a mounting port 213 communicating with the water supply channel 211. Multiple water spray holes 214 are also provided on the front side of the water spray base 21, and each water spray hole 214 communicates with a corresponding water outlet channel 212. The connecting pipe 22 has multiple connecting holes 221 on its wall. The connecting pipe 22 is sealed and inserted into the mounting port 213 and extends into the water supply channel 211. The connecting holes 221 communicate with the corresponding water outlet channels 212. The second ultraviolet LED lamp 23 is located at the end of the connecting pipe 22 and is configured to irradiate ultraviolet light into the connecting pipe 22.

[0098] The water pump 3, the heating container 11, and the connecting pipe 22 are connected in sequence.

[0099] Specifically, during use, the heating container 11 in the heating mechanism 1 can be irradiated by the first ultraviolet LED lamp 14 to achieve sterilization and bacteriostasis. 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 bacteriostasis. Ultraviolet light is used to sterilize the stored water, thereby reducing the continuous growth of bacteria in the stored water.

[0100] Furthermore, the heating container 11 includes a heating cylinder 111, a first end cap 112 and a second end cap 113, the heating cylinder 111 is connected between the first end cap 112 and the second end cap 113, and a heating cavity is formed between the heating cylinder 111, the first end cap 112 and the second end cap 113;

[0101] The heating cylinder 111 is further provided with an extension 117 at the end adjacent to the second end cap 113, and the extension 117 protrudes from the outer wall of the heating cylinder 111.

[0102] The extension 117 is provided with a through hole 118, and the surface of the extension 117 opposite to the second end cap 113 is also provided with a connecting water tank 119, which connects the through hole 118 and the port of the heating cylinder 111.

[0103] The first quartz plate 13 is sandwiched between the heating cylinder 111 and the second end cap 113, and the first quartz plate 13 also seals and covers the through hole 118 and the connecting water tank 119.

[0104] The connecting pipe 22 is sealed and inserted into the through hole 118, and the connecting pipe 22 is connected to the heating cavity through the connecting water tank 119; the first ultraviolet LED lamp 14 and the second ultraviolet LED lamp 23 are disposed between the first quartz plate 13 and the second end cap 113.

[0105] The first ultraviolet LED lamp 14 is disposed at the port of the heating cylinder 111 and is configured to irradiate ultraviolet light into the heating cylinder 111 through the first quartz plate 13;

[0106] The second ultraviolet LED lamp 23 is disposed at the through hole 118 and configured to irradiate ultraviolet light into the connecting pipe 22 through the first quartz plate 13 and the through hole 118.

[0107] Specifically, since the water output from the heating mechanism 1 is transported into the spray seat 21 through the connecting pipe 22 and sprayed out from the spray 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.

[0108] Since the end of the connecting tube 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, the second ultraviolet LED lamp 23 can irradiate ultraviolet light through the first quartz plate 13 and irradiate the connecting tube 22 through the through hole 118.

[0109] Since the first ultraviolet LED lamp 14 and the second ultraviolet LED lamp 23 are installed together between the second end cover 113 and the first quartz plate 13, it is convenient for centralized assembly on the one hand, and convenient for the second ultraviolet LED lamp 23 to irradiate the inside of the connecting tube 22 from the end of the connecting tube 22 on the other hand.

[0110] Furthermore, the pipe body of the connecting pipe 22 exposed between the spray base 21 and the extension 117 is also provided with a protective pipe 26, which wraps around the outside of the connecting pipe 22 and is located between the spray base 21 and the extension 117.

[0111] Specifically, since ultraviolet light needs to be irradiated in the connecting pipe 22, and part of the connecting pipe 22 will extend outside the spray base 21 and the corresponding port of the connecting pipe 22 needs to be inserted into the through hole 118, the protective pipe 26 is sleeved on the outside of the connecting pipe 22. On the one hand, it can protect the connecting pipe 22, and on the other hand, it can reduce the amount of ultraviolet light reaching the outside of the connecting pipe 22, thereby improving the sterilization intensity of ultraviolet light inside the connecting pipe 22.

[0112] Meanwhile, the two ends of the connecting pipe 22 are inserted into the spray seat 21 and the extension 117 respectively. Normally, in order to meet the requirements of a sealed connection, both ends of the connecting pipe 22 are fitted with sealing rings (unmarked). The end of the protective pipe 26 can abut against the sealing ring on the corresponding side to press the sealing ring tightly and achieve a good seal for the connecting pipe 22.

[0113] Furthermore, the second end cap 113 is also provided with an annular rib 115, which surrounds and forms an installation area.
