Description

Technical Field

[0001] This invention belongs to the field of water purification technology, and in particular relates to a filter bottle, a matching water circuit board, and a water purifier composed of such a filter bottle and water circuit board. Background Technology

[0002] Water purifiers with a filtration system consisting of filter bottles and a water circuit board are the most common type on the market. They integrate various water circuits, valves, pumps, etc., onto a single water circuit board, and then connect the filter bottles to the board for filtration. When filter bottles need to be replaced, they can be easily removed from the water circuit board and new ones installed. This structure makes the internal structure of the water purifier simple, neat, and organized, and consumers can replace the filter bottles without professional tools, thus making it the mainstream model. For example, the applicant's earlier Chinese patent application CN213569933U discloses such a water purifier including filter bottles and a water circuit board.

[0003] This method is suitable for filter bottles using materials such as activated carbon, PP cotton, and RO membranes as filter elements, as they only require water circuit connection, making replacement very convenient. Electroadsorption filter elements are another popular type of filter element. They are also made of wound membrane material and include at least one of the following: bipolar membrane electro-deionization filter elements, ion exchange resin filter elements, capacitive desalination filter elements, membrane capacitive desalination filter elements, and electro-regenerative ion exchange filter elements. Their working principle is to use the space between adjacent membranes as a flow channel, applying different potentials to adjacent membranes. In one case, the anions and cations in the influent are adsorbed onto the corresponding electrode membrane, thus obtaining purified water; in another case, the polarity of adjacent membranes reverses, and the ions adsorbed on the membranes return to the influent, resulting in a higher concentration of saline solution. This process is also called regeneration. For example, CN113402073A, CN212403789U, and CN212403777U disclose water purifiers using electroadsorption filter elements.

[0004] Electroadsorption filter cartridges require electricity to operate, so an electrical connection is still needed after connecting them to the water circuit board. Obviously, this prevents ordinary consumers from replacing the filter bottles themselves, causing inconvenience. Summary of the Invention

[0005] The purpose of this invention is to provide a filter bottle suitable for electroadsorption filter cartridges, a matching water circuit board, and a water purifier composed of such a filter bottle and water circuit board.

[0006] The present invention adopts the following technical solution: a filter bottle, including a filter bottle shell, an electroadsorption filter element inside the filter bottle shell, and a front end cap and a rear end cap at both ends of the filter bottle shell, which fix and encapsulate the filter element in the inner cavity of the filter bottle shell; the rear end cap of the filter bottle has an inlet port and an outlet port, characterized in that: the rear end cap of the filter bottle also has two electrical connectors.

[0007] The electrical connector is a plug-in type.

[0008] The inlet and outlet ports are arranged on the same radius of the rear end cap of the filter bottle, and the two electrical connectors are located on both sides of the line connecting the inlet and outlet ports.

[0009] The filter bottle is used horizontally, with its axis in the horizontal direction.

[0010] Of course, filter bottles can also be used vertically, even if they are perpendicular to the horizontal plane.

[0011] The present invention also adopts the following technical solution: a water circuit board, comprising several bases for inserting filter bottles, each base having two water nozzles for connecting the inlet and outlet ports of the filter bottles; the water nozzles of adjacent bases are connected by water channels pre-processed inside the water circuit board; characterized in that: each base has two electrical connectors, which are connected to a power source through a pre-set circuit inside the water circuit board.

[0012] The electrical connector is a plug-in type.

[0013] The two water nozzles are arranged on the same radius of the base, and the two electrical connectors are located on both sides of the line connecting the two water nozzles.

[0014] The water channel plate is used vertically, and the plane on which each base is located is perpendicular to the horizontal plane.

[0015] When the filter bottle is used vertically, the water circuit board can also be used horizontally, with the base parallel to the horizontal plane.

[0016] The present invention also adopts the following technical solution: a water purifier, characterized in that: it includes the aforementioned water circuit board and filter bottles, the number of filter bottles is the same as the number of bases on the water circuit board, the filter bottles are inserted into the bases, the inlet and outlet ports of the filter bottles are connected to the water nozzles of the water circuit board, and the electrical connectors of the filter bottles are connected to the electrical connectors of the water circuit board.

[0017] This invention integrates the circuitry onto the water circuit board, making the water circuit board also a circuit board. The connection between the filter bottle and the water circuit board serves as both a water circuit connection and a circuit connection. The filter bottle replacement operation in this invention is the same as in existing technologies, but it eliminates the need for additional power-off and power-on procedures, making it more convenient and faster.

[0018] Figure 1 This is a cross-sectional schematic diagram of the filter bottle of the present invention.

[0019] Figure 2 This is a schematic diagram of the rear end cap of the filter bottle of the present invention.

[0020] Figure 3 This is a schematic diagram of the water circuit board of the present invention. Detailed Implementation

[0021] See the attached drawings. The filter bottle of this embodiment includes a filter bottle shell 10. After the electroadsorption filter element 13 is installed in it, the front cover 11 and the rear cover 12 encapsulate the filter element to form a complete filter bottle. The rear cover 12 has two water ports and two electrical ports, namely a water inlet port 121, a water outlet port 122, a positive terminal connector 123, and a negative terminal connector 124.

[0022] The water circuit board 2 has three bases 21, 22, and 23, which can correspond to three filter bottles. Since the three bases are identical, only one of them will be described. Base 23 is equipped with two water nozzles 232 and 232, as well as a positive terminal connector 233 and a negative terminal connector 234.

[0023] When assembling the water circuit board and filter bottle into a water purifier, the orientation shown in the attached diagram is as follows: the water circuit board is placed vertically, with the axes of each base parallel to the horizontal direction. In this configuration, the two electrical connectors 233 and 234 are on the same horizontal line, and the two water nozzles 231 and 232 are on the same vertical line. The filter bottle is placed horizontally, with its axis parallel to the horizontal direction. In this configuration, the two electrical connectors 123 and 124 are on the same horizontal line, and the inlet port 121 and outlet port 122 are on the same vertical line, with the outlet port higher than the inlet port. After the filter bottle is inserted into the water circuit board, the inlet port 121 connects to the water nozzle 231, the outlet port 122 connects to the water nozzle 232, connectors 123 and 234 are electrically connected, and connectors 124 and 233 are electrically connected, thus completing the water and electrical connections in one step. To replace the filter bottle, simply remove it.
