Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a pre-filter valve head. Background Technology

[0002] A pre-filter valve head is a key component in domestic or industrial water treatment systems. It is usually installed on the main water inlet pipe to filter out large particulate impurities in the water, such as sand, mud, and rust, in order to protect downstream water purification equipment and household appliances from damage and extend their service life.

[0003] Current pre-filter valve heads, when in use, produce water with poor safety, as the water is prone to containing microorganisms, bacteria, and viruses, affecting its usability and reducing water safety and quality. Furthermore, in cold climates, inadequate anti-freezing measures can easily lead to freezing damage, affecting normal operation and reducing cold resistance and equipment safety. Therefore, those skilled in the art have provided a pre-filter valve head to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pre-filter valve head. Through the inclusion of a disinfection device, it can destroy the DNA or RNA of microorganisms, preventing their reproduction and survival, and effectively kill bacteria, viruses, and other pathogens, thus achieving water disinfection and improving water quality and safety. Then, through the inclusion of a mineral release device, it allows minerals to be slowly released and dissolved in the water, mixing with it and improving the taste, making it fresher and more palatable, thereby enhancing the water's flavor and health benefits. Finally, the heating element heats the outer shell of the bottle, and the ceramic insulating shell provides low thermal conductivity and excellent high-temperature resistance, preventing freezing damage in cold climates and improving cold resistance and safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-filter valve head, comprising a valve head body, an inlet located at the center of one side of the valve head body, an outlet located at the center of the other side of the valve head body, a connection port located at the center of the lower end face of the valve head body, a bottle body located at the output end of the connection port, a drain ball valve located at the output end of the bottle body, a filter element located at the center inside the bottle body, a sealing element located near the lower center of the inner wall of the output end of the bottle body, a heating wire wound around the outside of the connection port, a heat insulation shell fitted around the center of the outer side of the heating wire, a mineral release device located near the center of the upper end face of the valve head body, and a disinfection device located at the center inside the outlet.

[0006] The above technical solution, through the setting of the disinfection device, enables it to destroy the DNA or RNA of microorganisms, prevent their reproduction and survival, and effectively kill bacteria, viruses and other pathogens, thereby achieving water disinfection and improving water quality and the safety of water use.

[0007] Furthermore, the mineral release device includes a storage tank, a sealing cover, and a discharge port. The storage tank is located on the upper end face of the valve head body, the sealing cover is located at the center of the upper end face of the storage tank, and the discharge port is located at the center of the lower inner wall of the storage tank. The output end passes through the storage tank and the upper end face of the valve head body in sequence and extends to the upper inner wall of the valve head body.

[0008] The above technical solution, through the opening and closing of the sealed lid, allows workers to put minerals into the storage tank, store the minerals in the storage tank, and then transport them to the water outlet through the discharge port to mix with water. This allows the minerals to slowly dissolve into the water, mix with the water, and improve the taste of the water, making it fresher and more palatable, thereby improving the taste and health benefits of the water.

[0009] Furthermore, a plate valve is provided at the upper center of the discharge port, and a rotary motor is provided at the upper center of one side of the discharge port. The output end of the rotary motor passes through one side wall of the discharge port and extends to one inner side wall of the discharge port, and is fixedly connected to the plate valve.

[0010] The above technical solution uses a rotary motor to drive the plate valve to rotate, which enables control over the feeding of minerals, avoiding both excessive and insufficient feeding, thereby ensuring the mixing effect of minerals and water.

[0011] Furthermore, the disinfection device includes two fixed frames, two support rods, and multiple ultraviolet lamps. The two fixed frames are respectively located at the center of the upper inner wall and the center of the lower inner wall of the water outlet. The two support rods are respectively located at the center of the two fixed frames near both sides. The multiple ultraviolet lamps are arranged vertically at the center of the two support rods.

[0012] The above technical solution, through the fixing of the bracket and the support of the support rod, satisfies the need for fixed support of the ultraviolet lamp tube, avoiding damage caused by excessive water flow impact. Then, the ultraviolet lamp tube irradiates the water, which can destroy the DNA or RNA of microorganisms, prevent their reproduction and survival, and effectively kill bacteria, viruses and other pathogens, thereby achieving water disinfection and improving water quality and the safety of water use.

[0013] Furthermore, both the inlet and outlet are provided with threads at their outer center;

[0014] The above technical solution utilizes threads on the outside of the inlet and outlet to facilitate connection with the main water inlet pipe.

[0015] Furthermore, the connection port is connected to the bottle body in a through manner;

[0016] The above technical solution, through the connection between the connector and the bottle body, satisfies the requirements for water flow and filtration.

[0017] Furthermore, the heat-insulating outer shell is made of ceramic material;

[0018] The above technical solution utilizes a ceramic insulating shell, which has low thermal conductivity and excellent high-temperature resistance, preventing equipment from freezing and being damaged in cold climates, thereby improving cold resistance and safety.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, when the pre-filter valve head is used, the disinfection device is designed to destroy the DNA or RNA of microorganisms, prevent their reproduction and survival, and effectively kill bacteria, viruses and other pathogens, thereby disinfecting the water and improving the safety of water quality and water use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 This utility model provides an embodiment of a pre-filter valve head, comprising a valve head body 1, an inlet 2 at the center of one side of the valve head body 1, an outlet 3 at the center of the other side of the valve head body 1, a connection port 4 at the center of the lower end face of the valve head body 1, a bottle body 5 at the output end of the connection port 4, a drain ball valve 6 at the output end of the bottle body 5, a filter element 7 at the center inside the bottle body 5, a sealing element 8 at the lower center of the inner wall of the output end of the bottle body 5, a heating wire 9 wound around the outside of the connection port 4, and a heat insulation shell 10 fitted around the center of the outside of the heating wire 9. The heating wire 9 heats the outer shell of the bottle body 5, and the heat insulation shell 10, made of ceramic material, gives it low thermal conductivity and excellent high-temperature resistance, preventing it from leaking in cold weather. Climate causes freezing damage to equipment, thus improving cold resistance and safety. A mineral release device 11 is provided on one side of the center of the upper end face of the valve head body 1. The mineral release device 11 allows minerals to be slowly released and dissolved into the water, mixing with the water and improving the taste of the water, making it fresher and more palatable, thereby improving the taste and health benefits of the water. A disinfection device 12 is provided in the center of the inside of the outlet 3. The disinfection device 12 can destroy the DNA or RNA of microorganisms, preventing their reproduction and survival, and can effectively kill bacteria, viruses and other pathogens, thus achieving water disinfection and improving water quality and the safety of water use.

[0031] The mineral release device 11 includes a storage tank 1101, a sealing cap 1102, and a discharge port 1103. The storage tank 1101 is located on the upper end face of the valve head body 1, the sealing cap 1102 is located at the center of the upper end face of the storage tank 1101, and the discharge port 1103 is located at the center of the lower inner wall of the storage tank 1101. The output end passes through the storage tank 1101 and the upper end face of the valve head body 1 in sequence and leads to the upper inner wall of the valve head body 1. By opening and closing the sealing cap 1102, the device allows the operator to put minerals into the storage tank 1101, store the minerals in the storage tank 1101, and then transport them to the water outlet 3 through the discharge port 1103 to mix with water. This allows the minerals to be slowly released and dissolved in the water, mixing with the water and improving the taste of the water, making it fresher and more palatable, thereby improving the taste and health benefits of the water.

[0032] A plate valve 1104 is located at the upper center of the discharge port 1103. A rotary motor 1105 is located at the upper center of one side of the discharge port 1103. The output end of the rotary motor 1105 passes through one side wall of the discharge port 1103 and extends to one inner side wall of the discharge port 1103, and is fixedly connected to the plate valve 1104. The rotary motor 1105 drives the plate valve 1104 to rotate, which satisfies the control of the mineral feeding, avoids too much or too little, and thus ensures the mixing effect of minerals and water.

[0033] The disinfection device 12 includes two fixed frames 1201, two support rods 1202, and multiple ultraviolet lamps 1203. The two fixed frames 1201 are respectively located at the center of the upper inner wall and the center of the lower inner wall of the outlet 3. The two support rods 1202 are respectively located at the center of the two fixed frames 1201 on both sides. The multiple ultraviolet lamps 1203 are arranged vertically at the center between the two support rods 1202. The fixed frames 1201 and the support rods 1202 fix and support the ultraviolet lamps 1203, preventing damage caused by excessive water flow impact. The ultraviolet lamps 1203 irradiate the water, which can destroy the DNA or RNA of microorganisms, prevent their reproduction and survival, and effectively kill bacteria, viruses and other pathogens, thereby disinfecting the water and improving the water quality and safety of water use.

[0034] Both the inlet 2 and outlet 3 have threads at their outer center, which allow them to connect to the main water inlet pipe. The connection port 4 is connected to the bottle body 5, allowing for water flow and filtration. The heat insulation shell 10 is made of ceramic material, which gives it low thermal conductivity and excellent high-temperature resistance, preventing freezing damage to the equipment in cold climates and thus improving cold resistance and safety.

[0035] Working Principle: When the pre-filter valve head is in use, the threads on the outside of the inlet 2 and outlet 3 allow it to connect to the main water inlet pipe. The connection port 4 then connects it to the bottle body 5, ensuring water flow and filtration. The heating wire 9 heats the outer shell of the bottle body 5. The ceramic insulating shell 10 provides low thermal conductivity and excellent high-temperature resistance, preventing freezing damage in cold climates and improving cold resistance and safety. The sealing cap 1102 allows operators to add minerals to the storage tank 1101, where they are stored. The minerals are then transported to the outlet 3 through the outlet 1103 to mix with water, allowing for slow dissolution. When added to water, it mixes with the water, improving the taste and making it fresher and more palatable, thus enhancing the water's flavor and health benefits. A rotating motor 1105 drives a plate valve 1104 to rotate, controlling the amount of minerals added and preventing over- or under-addition, ensuring proper mixing. Finally, a fixing bracket 1201 and a support rod 1202 secure the ultraviolet lamp 1203, preventing damage from excessive water flow. The ultraviolet lamp 1203 then irradiates the water, destroying the DNA or RNA of microorganisms, inhibiting their reproduction and survival, and effectively killing bacteria, viruses, and other pathogens, thus disinfecting the water and improving water quality and safety.
