DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-3As shown, a water dispenser filter element replacement reminder device includes a water dispenser assembly 1, an outer wall of the water dispenser assembly 1 is provided with a reminder screen 103, a filter element 207 capable of maintaining vertical reciprocating motion is provided inside the water dispenser assembly 1, a first electric switch 106 is provided between the bottom of the filter element 207 and the inside of the water dispenser assembly 1, a water inlet mechanism is provided on the top of the filter element 207, the water inlet mechanism maintains threaded engagement with the water dispenser assembly 1, a driving fan blade 204 is provided on the top of the water inlet mechanism to drive the water inlet mechanism to maintain axial rotation, a second electric switch 206 is provided between the bottom of the water inlet mechanism and the water dispenser assembly 1, and the first electric switch 106 and the second electric switch 206 are maintained in series to connect the reminder screen 103.

[0027] The main purpose of the water dispenser filter replacement reminder device is to drive the fan blade 204 and the water injection rotary block 201 to maintain threaded engagement with the water injection hole 102, so that the water injection rotary block 201 can keep the second electric switch 206 disconnected by rotating during the water injection process, thereby disconnecting the connection circuit of the reminder screen 103, and avoiding the sinking of the filter element 207 due to the water injection work, thereby causing a misjudgment; the torsion spring 205 arranged at the bottom of the driving fan blade 204 is also driven. When there is no water injection work, the torsion spring 205 drives the connecting shaft 203 to rotate in the opposite direction, so that the water injection rotary block 201 rotates in the opposite direction to keep the second electric switch 206 connected, and then it can be extended through the bellows 208. When there are too many impurities in the filter element 207, the electrode switch 209 at the bottom is kept connected to the first electric switch 106 due to the action of gravity, so that the reminder screen 103 performs the reminder work.

[0028] In the technical solution provided by this utility, Figure 1 , Figure 2 and Figure 3 It can be seen that the water dispenser assembly 1 includes a shell 101, and a water injection hole 102 is opened on the top of the shell 101, through which water can be injected and filtered inside, and a filter element groove 104 is also opened inside the shell 101, and the water injection hole 102 is kept in communication with the filter element groove 104, so that water can be filtered through the filter element 207.

[0029] Furthermore, a reminder component 2 is also provided inside the filter element slot 104, and the reminder component 2 includes a water inlet mechanism arranged inside the water injection hole 102, and the water inlet mechanism specifically includes a water injection rotary block 201 which is engaged and connected to the inner wall of the water injection hole 102 and is in a "convex" shape. Through the rotation of the water injection rotary block 201, the water injection rotary block 201 can be reciprocated vertically in the filter element slot 104, so that the second electric switch 206 is reciprocatedly disconnected and connected, and a water inlet slot 202 is opened inside the water injection rotary block 201, so that water can be poured from the water inlet slot 202 into the interior of the filter element slot 104, and filtered through the internal filter element 207.

[0030] Furthermore, a connecting shaft 203 is provided running through the interior of the water inlet groove 202, and the end of the connecting shaft 203 close to the outer wall of the shell 101 is provided with driving blades 204 distributed in a circular array. By keeping the driving blades 204 tilted, when the water is injected, the driving blades 204 generate a lateral thrust, thereby rotating, and the end of the connecting shaft 203 close to the filter element groove 104 is connected to the bottom of the water injection rotary block 201, so that the rotation of the driving blades 204 drives the rotation of the entire water injection rotary block 201, thereby performing vertical movement, thereby driving the second electric switch 206 to disconnect.

[0031] Furthermore, a torsion spring 205 sleeved on the outer wall of the connecting shaft 203 is provided at the bottom of the driving blade 204. Through the torsion spring 205, the connecting shaft 203 can be reset and rotated when there is no water injection work, so that the water injection rotating block 201 is reset, so that the second electric switch 206 is connected again.

[0032] Furthermore, a second electric switch 206 is provided between the water injection rotary block 201 and the top of the filter element slot 104, and the water injection rotary block 201 is driven to maintain axial rotation by driving the fan blade 204 so as to disconnect the second electric switch 206, and the output end of the second electric switch 206 is connected to the prompt screen 103 and maintains series operation, at which time the prompt screen 103 will not perform prompt work.

[0033] Furthermore, a filter element 207 is slidably disposed inside the filter element slot 104, and a bellows 208 is disposed on the top of the filter element 207. Due to the extensibility of the bellows 208, when there are too many impurities or too much water inside the filter element 207, the entire filter element 207 will slide down, and an electrode switch 209 is disposed at the bottom of the filter element 207. The filter element 207 is driven to maintain vertical reciprocating motion, which can drive the electrode switch 209 to maintain electrical connection with the first electrical switch 106, thereby driving the first electrical switch 106 to remain turned on.

[0034] Furthermore, a power supply 105 is provided inside the housing 101, and the power supply 105 is connected in series with the first electric switch 106, the second electric switch 206 and the prompt screen 103. When water is injected, the second electric switch 206 is disconnected by the vertical displacement of the water injection rotary block 201. At this time, no matter whether the filter element 207 sinks due to internal moisture or internal impurities, causing the first electric switch 106 to be connected, the entire circuit cannot be connected, and thus the prompt screen 103 cannot perform a prompting operation to avoid accidental touch. When the water injection operation is not in progress, the water injection rotary block 201 is reset to cause the second electric switch 206 to remain connected. At this time, all the moisture inside the filter element 207 is also filtered and discharged. Only when there are too many impurities inside the filter element 207 will the filter element 207 sink and the first electric switch 106 be connected. At this time, the entire circuit remains connected and the prompt screen 103 will perform a prompting operation.

[0035] Working principle: First, water is injected into the water injection hole 102. The water impacts the driving blade 204, causing the driving blade 204 to rotate axially, thereby driving the water injection rotating block 201 to rotate downward, disconnecting the second electric switch 206, and the water enters the filter element slot 104 through the water inlet slot 202, and is filtered through the filter element 207;

[0036] When the filter element 207 performs filtering, there will be moisture and residual impurities inside, causing the filter element 207 to slide down through the extendable and contractible bellows 208, so that the first electrical switch 106 and the electrode switch 209 are in contact and connected. However, since the first electrical switch 106 and the second electrical switch 206 are connected in series, the entire circuit cannot be connected at this time.

[0037] When more water injection and filtering work is performed, more impurities will accumulate inside the filter element 207. When no water injection work is performed, the water injection block 201 is reset and rotated by the torsion spring 205 to keep the second electric switch 206 connected. At this time, the filter element 207 sinks through more impurities. At this time, the first electric switch 106 is connected to the electrode switch 209 and remains connected. At this time, the circuit composed of the power supply 105, the first electric switch 106, the second electric switch 206 and the prompt screen 103 remains connected, so that the prompt screen 103 prompts the replacement of the filter element 207.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
