[0079] Example 1: Figure 1-Figure 7 As shown, the embodiment of the present application provides a decorative cover with a sterilization function, comprising

[0080] The cover 1 is provided with a mounting and fixing portion (not marked);

[0081] The sterilization component 2 includes a fan 21, an air duct 22 and a sterilization component 23. The air duct 22 has an air inlet and an air outlet. The fan 21 is arranged on the air duct 22. The sterilization component 23 is arranged in the air duct 22 and is used to sterilize the air flow flowing through the air duct 22; the sterilization component 2 is arranged on the said mounting and fixing part.

[0082] Specifically, when the decorative cover with a sterilization function is in use, the cover shell 1 is mounted on the outer shell of the water heater to achieve a matching use. When the user is bathing, the fan 21 is turned on to circulate the air in the bathroom into the air duct 22, and the sterilization component 23 in the air duct 22 sterilizes the air flowing through the air duct 22.

[0083] As the user bathes in the bathroom, the hot and humid gas generated circulates into the air duct 22 for timely and effective sterilization, ensuring that the air quality in the bathroom remains safe and healthy, thereby effectively improving the user experience.

[0084] In some embodiments, one end of the air duct 22 forms the air inlet, the other end of the air duct 22 is a closed structure, the side wall of the air duct 22 is provided with the air outlet, and the fan 21 is connected to the air inlet.

[0085] Specifically, during the actual air supply process, the air flow after sterilization through the air duct 22 is output from the air outlet arranged along the length direction of the air duct 22 to increase the air outlet coverage area and effectively disperse the sterilized air to the bathroom.

[0086] In one embodiment, a through hole 11 is provided on the cover 1 ; a side wall of the air duct 22 is provided with an outwardly protruding air outlet nozzle 24 , the air outlet nozzle 24 forms the air outlet, and the air outlet nozzle 24 is inserted into the through hole 11 .

[0087] Specifically, an outwardly protruding air outlet nozzle 24 is provided on the side wall of the air duct 22 to output the sterilized air. The air discharged from the air outlet nozzle 24 forms an air curtain, which is softer and covers a wider area. In addition, since the airflow output from the air duct 22 is output through the air outlet nozzle 24, it can effectively prevent the air path of the air duct 22 from short-circuiting and avoid the mutual influence of the incoming and outgoing air.

[0088] The bottom of the housing 1 is provided with a through-hole 11. Specifically, air is discharged from the bottom of the housing 1 through an air outlet 24, which extends outward and passes through the through-hole 11 to better transport air downward. The transported air, heated by the hot water in the bathroom, rises upward, thereby sterilizing the air throughout the bathroom on a larger scale, thereby optimizing the air quality throughout the bathroom.

[0089] In other embodiments, in order to meet the air intake requirements of the air duct 22, an air suction port 12 is further provided on the side of the cover 1; and / or the back of the cover 1 is an open structure.

[0090] Specifically, the air duct 22 is arranged as a whole along the length direction of the cover shell 1, and the fan 21 is arranged at one end of the air duct 22 to connect to the air inlet. In this way, an air suction port 12 can be set on the end face of the cover shell 1 near the end of the fan 21 to meet the requirement that the air in the bathroom is sucked into the air duct 22 by the fan 21.

[0091] Similarly, for the cover 1 , the back thereof is an open structure, and the fan 21 can directly draw air from the back of the cover 1 .

[0092] In one embodiment of the present application, the decorative cover with a sterilization function also includes a control component 3, which includes a mounting cover 31 and an electric control board 32. The electric control board 32 is arranged on the mounting cover 31, and the mounting cover 31 is arranged on the cover shell 1. The electric control board 32 is electrically connected to the fan 21 and the sterilization component 23.

[0093] Specifically, in order to facilitate the user to control the sterilization component 2, a control component 3 can be configured, and the electric control board 32 in the control component 3 can control the operation of the sterilization component 2. Among them, the electric control board 32 can be configured with an independent power line or powered by the water heater.

[0094] In one embodiment, in order to facilitate the installation of the control component 3 and facilitate user operation, a hollow opening 13 is provided on the front of the cover 1. The control component 3 also includes a decorative panel 33. The installation cover 31 is provided on the decorative panel 33. The decorative panel 33 is clamped on the cover 1 and covers the hollow opening 13. The installation cover 31 passes through the hollow opening 13.

[0095] Specifically, the hollow opening 13 configured on the housing 1 allows for installation of the control assembly 3 from the front side of the housing 1, while the decorative panel 33 obscures the hollow opening 13 to enhance the overall appearance. The touch buttons electrically connected to the electronic control board 32 are arranged on the decorative panel 33 for user convenience.

[0096] In another embodiment, the sterilization component 23 can be physically represented in a variety of ways. For example, the sterilization component 23 can be a UV lamp positioned within the air duct 22, thereby sterilizing the airflow entering the air duct 22 through UV light. Alternatively, the sterilization component 23 can be an ozone generator positioned at the air inlet of the air duct 22, capable of releasing an appropriate amount of ozone to sterilize the airflow flowing within the air duct 22.

[0097] By setting a sterilization component in the cover, the fan configured in the sterilization component can suck the air in the bathroom into the air duct, and the air flow flowing in the air duct can be sterilized by the sterilization component. After the air is sterilized by the sterilization component, it will be output from the air outlet of the air duct and flow back into the bathroom. In this way, the air in the bathroom can circulate into the air duct for sterilization, so as to purify the air in the bathroom and improve the user experience.

[0098] Example 2: Figures 8-18 As shown, the embodiment of the present application provides a water heater, comprising a shell 4 and an inner tank (not shown) disposed in the shell 4, wherein the inner tank is provided with a water inlet pipe 5 and a water outlet pipe 6, and the water inlet pipe 5 and the water outlet pipe 6 extend to the outside of the shell 4,

[0099] The water heater further comprises the above-mentioned decorative cover with sterilization function; the cover shell 1 of the decorative cover with sterilization function is arranged on the outer shell 4 and is located in front of the water inlet pipe 5 and the water outlet pipe 6.

[0100] Specifically, the water heater can be an electric heater or a heat pump water heater and other physical entities. By configuring a decorative cover with a sterilization function, the function of the water heater itself can be increased, thereby meeting the user's requirement for sterilizing the air in the bathroom space during bathing.

[0101] In another embodiment of the present application, the water heater further includes an anti-leakage valve module 7, which includes:

[0102] A first water pipe 100 is provided with a first water inlet pipe head 101, a first connecting pipe head 102, and a first water outlet pipe head 103. A first connecting flow channel 104 is further provided in the first water pipe 100. Port 1 of the first connecting flow channel 104 is connected to the first water inlet pipe head 101, and port 2 of the first connecting flow channel 104 is connected to the first connecting pipe head 102 and the first water outlet pipe head 103 respectively.

[0103] The second water pipe 200 is provided with a second water inlet pipe head 201, a second connecting pipe head 202, and a second water outlet pipe head 203. The second water inlet pipe head 201 is provided with a one-way valve 208, which is used to control the one-way flow of water from the second water inlet pipe head 201 into the second water pipe 200;

[0104] The automatic anti-leakage valve 300 includes a spring 301 and a sealing valve head 302. The sealing valve head 302 is slidably disposed within the first connecting pipe head 102 and is used to open and close port 2 of the first connecting channel 104. The spring 301 is disposed within the first connecting pipe head 102 and is used to apply an elastic force to the sealing valve head 302 toward port 2 of the first connecting channel 104.

[0105] The connecting pipe 400 is disposed between the first connecting pipe head 102 and the second connecting pipe head 202 .

[0106] Specifically, the anti-leakage valve module 7 provided in the embodiment of the present application is used to be installed on the inlet and outlet water pipes of the water heater in the user's home to protect the water heater from water leakage.

[0107] The anti-leakage valve module 7 mainly includes a first water pipe 100 , a second water pipe 200 , an automatic anti-leakage valve 300 and a connecting pipe 400 .

[0108] The first water inlet pipe head 101 configured for the first water pipe 100 is used to connect to the external water supply pipe to introduce tap water from the municipal pipe network, and the first water outlet pipe head 103 of the first water pipe 100 is connected to the water inlet pipe port of the water heater in the user's home to transport the tap water to the water heater.

[0109] The second water inlet pipe 201 of the second water pipe 200 is connected to the water outlet of the water heater, thereby outputting the treated water from the water heater. The second water outlet pipe 203 of the second water pipe 200 is connected to the water terminal in the user's home to achieve the final output of water.

[0110] The first water pipe 100 and the second water pipe 200 are connected via a connecting pipe 400 , so that the first connecting pipe head and the second connecting pipe head are connected to each other.

[0111] For the automatic anti-leakage valve 300 in the first connecting head, the sealing valve head 302 configured therein can move back and forth in the first connecting head according to the different water pressure differences on both sides, and then use the sealing valve head 302 to open and close the port 2 of the first connecting channel 104 to achieve the purpose of preventing water leakage.

[0112] During use, a conventional water heater is usually equipped with two external connectors for connecting to external water pipes. During installation, the first water outlet pipe head 103 is connected to one of the external connectors of the water heater, and the second water inlet pipe head 201 is connected to the other external connector of the water heater.

[0113] When the user uses water through the water terminal, the second water pipe 200 is connected to the water terminal through the second water outlet pipe to output water upward. At this time, the water pressure in the second water pipe 200 is lower than the water pressure out of the first water inlet pipe head 101. At the same time, the first connecting pipe head is connected to the second connecting pipe head through the connecting pipe 400, so the water pressure at the first connecting pipe head is also reduced accordingly.

[0114] The water introduced from the first water inlet pipe head 101 applies water pressure to one side of the sealing valve head 302 of the automatic anti-leakage valve 300 through port 2 of the first connecting channel 104, while the other side of the sealing valve head 302 is connected to the water terminal and connected to the outside world through the connecting pipe 400, the second connecting pipe head and the second water outlet pipe head 203, so that the other side of the sealing valve head 302 is in a static pressure state.

[0115] At this time, port two of the first connecting channel 104 pushes the sealing valve head 302 to overcome the elastic force of the spring 301 and move in the direction away from port two of the first connecting channel 104. During this process, the spring 301 is continuously compressed until the elastic force generated by the spring 301 is the same as the water pressure generated by the water pressure of port two of the first connecting channel 104 on the sealing valve head 302.

[0116] In this way, the water at the second port of the first connecting flow channel 104 pushes the sealing valve head 302 to be output and finally flows into the water heater through the first water outlet pipe head 103 .

[0117] After the user turns off the water terminal, the tap water pressure of the external water supply pipe is transmitted to the second water pipe 200, causing the water pressure of the first connecting pipe head to gradually increase and eventually become the same as the water pressure in the first water inlet pipe head 101.

[0118] The spring 301 pushes the sealing valve head 302 to move toward the second port of the first connecting channel 104 under its own elastic force until the sealing valve head 302 blocks and closes the second port of the first connecting channel 104 .

[0119] At this time, if the water heater itself is broken and leaking, since the second water inlet pipe head 201 of the second tube body is equipped with a one-way valve 208, leakage at the water terminal will not cause changes in the water pressure in the second tube body, and the automatic anti-leakage valve 300 will always be in a state of closing port 2 of the first connecting flow channel 104. Ultimately, even if the water heater is damaged, no tap water will be input into the water heater to cause serious leakage.

[0120] By configuring an automatic anti-leakage valve in the first water pipe, the sealing valve head in the automatic anti-leakage valve can slide back and forth in the first water pipe relative to the port 2 of the first connecting flow channel. The first water pipe is connected to the water supply pipe (tap water pipe) in the user's home through the first water inlet pipe head. The first water pipe and the second water pipe are respectively installed on the water heater in the user's home. When the water heater is in use, the water introduced by the first water pipe is processed by the water heater and then output from the second water pipe. At this time, since the connecting pipe connects the first connecting pipe head and the second connecting pipe head, the water pressure in the first connecting pipe head is lower than the water pressure in the first water inlet pipe head. At this time, the sealing valve head is pushed open by the water introduced by the first water inlet joint, so that the automatic anti-leakage valve opens the port 2 of the first connecting flow channel, and the first water inlet pipe head and The first water outlet pipe head is connected to supply water to the water heater; when the water heater is in the water-off state, the water pressures in the first water pipe and the second water pipe gradually become the same, so that the water pressure in the first water inlet pipe head and the first connecting pipe head is balanced. At this time, the automatic anti-leakage valve moves the sealing valve head toward the second port of the first connecting channel under the action of the spring, and finally, the sealing valve head automatically resets and closes the second port of the first connecting channel; in the event of water leakage inside the water heater, since the second water inlet pipe head is provided with a one-way valve, the water pressure in the first water inlet pipe head and the first connecting pipe head remains balanced, thereby ensuring that the water supply pipe will not output water from the first water pipe, thereby reducing leakage accidents and improving the reliability of the water heater.

[0121] In some embodiments, in order to facilitate the installation of the automatic anti-leakage valve 300, the automatic anti-leakage valve 300 also includes a connecting elbow 303 and an adjusting screw 304. A threaded hole is provided on the connecting elbow 303, and the adjusting screw 304 is threadedly connected in the threaded hole and rests on the spring 301; the connecting pipe 400 is connected to the first connecting pipe head through the connecting elbow 303.

[0122] Specifically, there are certain differences in the water pressure of water supply networks in different regions. Therefore, it is necessary to adjust the elastic force generated by the spring 301 on the sealing valve head according to the local water pressure, thereby ensuring that the sealing valve head can perform a good sealing effect on the first connecting channel 104.

[0123] During actual use, after the operator installs the anti-leakage valve module 7 on the water heater, he uses a screwdriver to turn the adjusting screw 304 to change the squeezing force of the adjusting screw 304 on the spring 301, and then adjusts the elastic force of the spring 301 in the initial state to ensure that the spring 301 can apply appropriate spring force to the sealing valve head 302, so as to meet the water pressure requirements of the local water supply network.

[0124] In another embodiment, the automatic anti-leakage valve 300 further includes an elastic diaphragm 305, which is located between the spring 301 and the sealing valve head 302. The elastic diaphragm 305 is arranged between the first connecting head and the connecting elbow 303, and the elastic diaphragm 305 is used to seal the outer pipe opening of the first connecting head.

[0125] Specifically, the elastic diaphragm 305 configured for the automatic anti-leakage valve 300 can block the first connecting pipe head to prevent the cold water introduced from the first water inlet pipe head 101 from directly entering the second water pipe 200 through the connecting pipe 400 .

[0126] In addition, the elastic diaphragm 305 is a flexible structure and can be deformed accordingly according to the magnitude of the force applied.

[0127] To this end, when the user uses water through the water terminal, the second water pipe 200 is connected to the water terminal through the second water outlet pipe to output water upward. The water pressure in the second water pipe 200 is lower than the water pressure out of the first water inlet pipe head 101, and under the action of the connecting pipe 400, a pressure difference is formed on both sides of the elastic diaphragm 305.

[0128] The water pressure at the second port of the first connecting flow channel 104 is relatively high, thereby pushing open the sealing valve head 302 , and the tap water enters the first connecting pipe head and is cut off by the elastic diaphragm 305 and does not flow into the connecting pipe 400 .

[0129] After the user turns off the water terminal, the tap water pressure of the external water supply pipe is transmitted to the second water pipe 200, and the water pressure of the first connecting pipe head gradually increases and eventually becomes the same as the water pressure in the first water inlet pipe head 101. At this time, the water pressure on both sides of the elastic diaphragm 305 is the same, and under the action of the spring 301, the elastic diaphragm 305 exerts an elastic force on the sealing valve head 302 to close the port 2 of the first connecting flow channel 104 through the sealing valve head 302.

[0130] In some embodiments, the sealing valve head 302 includes a valve body 3021 and a sealing plug 3022. The sealing plug 3022 is arranged on the valve body 3021. The valve body 3021 is slidably arranged in the first connecting pipe head. The sealing plug 3022 is arranged opposite to port 2 of the first connecting channel 104. The valve body 3021 is arranged on the elastic diaphragm 305.

[0131] Specifically, the valve body 3021 is used as a mounting component to mount the bearing sealing plug 3022 . The sealing plug 3022 is made of a flexible sealing material such as rubber or silicone, so as to perform a good seal on the second port of the first connecting channel 104 through the sealing plug 3022 .

[0132] The sealing valve head 302 adopts a split structure, uses the valve body 3021 to slide back and forth in the first connecting pipe head, and uses the sealing plug 3022 to effectively seal the edge of the second port of the first connecting channel 104.

[0133] In some embodiments, a first through hole 3023 is provided on the valve body 3021, and a second through hole 3024 is provided on the sealing plug 3022. The first through hole, the second through hole and the port two of the first connecting channel 104 are connected in sequence. The sealing plug 3022 is used to seal the edge of the port two of the first connecting channel 104, and the elastic diaphragm 305 covers the first through hole.

[0134] Specifically, the valve body 3021 and the sealing plug 3022 are respectively provided with through holes, and the tap water at the second port of the first connecting channel 104 can flow into the side of the elastic diaphragm 305 through the second through hole 3024 and the second through hole, thereby directly applying water pressure to the elastic diaphragm 305.

[0135] In another embodiment, in order to ensure that the valve body 3021 can slide smoothly in the first connecting head, and to ensure that the tap water introduced by the first water inlet pipe head 101 can smoothly enter the first connecting head to apply comprehensive pressure to the elastic diaphragm 305, the side wall of the valve body 3021 is also provided with a plurality of sliding ribs 3025 protruding outward, and the sliding ribs are abutted against the inner wall of the first connecting head.

[0136] When the user uses water through the water terminal, the valve body 3021 drives the sealing plug 3022 away from the second port of the first connecting channel 104, thereby allowing the tap water to flow into the first connecting pipe head through the first water inlet pipe head 101. The water flow can flow to the elastic diaphragm 305 through the gap between the valve body 3021 and the inner wall of the first connecting pipe head, so that the elastic diaphragm 305 obtains water pressure over a larger area.

[0137] In another embodiment, a sleeve 3031 is provided in the connecting elbow 303 , the threaded hole is formed in the sleeve, and the spring 301 is inserted into the sleeve.

[0138] Specifically, the spring 301 is inserted into the sleeve to position and install the spring 301 through the sleeve. At the same time, the adjusting screw 304 is threadedly connected to the sleeve to adjust the elastic force of the spring 301 in the initial state.

[0139] In order to increase the effective area of the spring 301 exerting force on the elastic diaphragm 305 , the automatic anti-leakage valve 300 further includes a top block 306 , which is slidably disposed in the sleeve and is located between the spring 301 and the elastic diaphragm 305 .

[0140] Specifically, the top block 306 is located between the spring 301 and the elastic diaphragm 305 , and the contact area formed between the top block 306 and the elastic diaphragm 305 is larger, so as to ensure that the elastic diaphragm 305 is subjected to uniform force.

[0141] At the same time, the top block 306 can slide in the sleeve to better apply elastic force to the elastic diaphragm 305.

[0142] In another embodiment, in order to facilitate the user to directly operate the water circuit opening and closing of the anti-leakage valve module 7, a first auxiliary joint 105 is provided on the first water pipe 100, a first partition 107 is provided in the first auxiliary joint 105, and a first water inlet (unmarked) and a first water outlet (unmarked) are provided on the first partition 107. The second port of the first connecting flow channel 104, the first water inlet, the first water outlet, and the first water outlet pipe head 103 are connected in sequence;

[0143] A first switching valve 106 is provided in the first auxiliary joint 105 . The first switching valve 106 is arranged opposite to the first partition plate 107 and is used to switch the first water inlet and / or the first water outlet.

[0144] Specifically, during actual use, when the user needs to completely close the anti-leakage valve module 7, the first switch valve 106 can be operated to switch the first water inlet and / or the first water outlet through the first switch valve 106 to actively control the flow path between the first water inlet pipe head 101 and the first water outlet pipe head 103, and then completely close the anti-leakage valve module 7 as needed, which is more conducive to further improving the reliability of use.

[0145] The specific structure of the first switch valve 106 can adopt the valve core structure of a conventional water valve, which is not limited or elaborated here.

[0146] In another embodiment, a second connecting channel 204 is further provided in the second water pipe 200, port 1 of the second connecting channel 204 is connected to the second water inlet pipe head 201, and port 2 of the second connecting channel 204 is connected to the second connecting pipe head 202 and the second water outlet pipe head 203 respectively.

[0147] Specifically, in order for the second water inlet pipe head 201 to meet the requirement of supplying water to the second water outlet pipe head 203 and the second connecting pipe head, a second connecting flow channel 204 is configured in the second water pipe 200 to realize water flow distribution.

[0148] Similarly, in order to completely close the second water pipe 200, a second auxiliary joint 205 is provided on the second water pipe 200, a second partition 206 is provided in the second auxiliary joint 205, a second water inlet and a second water outlet are provided on the second partition 206, and the second connecting channel 204 has a second water inlet, and the second water outlet is connected to the second water outlet pipe head 203 and the second connecting pipe head respectively; a second switch valve 207 is provided in the second auxiliary joint 205, and the second switch valve 207 is arranged opposite to the second partition 206 and is used to switch the second water inlet and / or the second water outlet.

[0149] Specifically, during actual use, when the user needs to completely close the second water pipe 200, the second switch valve 207 can be operated to switch the second water inlet and / or the second water outlet through the second switch valve 207 to actively control the flow path between the second water inlet pipe head 201 and the second water outlet pipe head 203 and the second connecting pipe head, and then completely close the second water pipe as needed, which is more conducive to further improving the reliability of use.
