Description

Technical Field

[0001] The utility model generally relates to the technical field of bathrooms, and in particular to a drainage speed increasing mechanism and a toilet. Background Art

[0002] The drainage structure of an existing toilet generally has a drain valve installed in the water tank, and the drain valve controls the opening and closing of the drainage pipe. When the drain valve is opened, the water in the water tank flows into the toilet through the drainage pipe, and the toilet is flushed by the gravitational potential energy of the water. In the above structure, the drainage speed of the drain valve and the flushing ability of the toilet are determined by the installation height of the water tank and the water level of the water tank. When the installation position of the toilet water tank is low or the water level is low, the gravitational potential energy is insufficient, resulting in a slow drainage speed of the drain valve and insufficient flushing ability of the toilet, which seriously affects the flushing effect of the toilet. In order to ensure that the toilet is flushed clean, more water needs to be used, resulting in a waste of water resources.

However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0028] The described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solution of the present invention may be practiced without one or more of the specific details, or other methods, components, materials, etc. may be used.

[0029] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0030] Example 1

[0031] See also Figure 1-2The embodiment of the present disclosure provides a drainage speed increasing mechanism 100, which is installed in a water tank 200 of a toilet. A drainage pipe 210 is provided at the bottom of the water tank 200, and a water outlet 211 of the drainage pipe 210 is connected to a toilet seat (not shown). The drainage pipe 210 forms a drainage channel 201 for water flow to flow through, so as to flush the toilet. The drainage speed increasing mechanism 100 includes a driving unit 110, a transmission unit 120, a pressure plate 130 and a drainage valve 140. The driving unit 110 is used to drive the transmission unit 120 to rotate, thereby driving the pressure plate 130 to rotate. The pressure plate 130 is arranged in the drainage channel 201 of the water tank 200 or in a channel connected to the drainage channel 201, for example, in a channel connected to the toilet seat and the drainage channel 201. When the pressure plate 130 rotates, the water flow in the drainage channel 201 or the channel in the toilet seat is pressurized, effectively increasing the drainage speed and flushing pressure. The pressurization principle is similar to the working principle of a propeller.

[0032] See also Figure 3 to Figure 6 In this embodiment, the driving unit 110 includes a water inlet body 111 and a rotating member 112 disposed in the water inlet body 111. The water inlet body 111 drives the rotating member 112 to rotate when water is inletted. Specifically, in one embodiment, the rotating member 112 is configured as an impeller, and the impeller includes a wheel shaft and a plurality of blades disposed around the wheel shaft. The blades rotate when impacted by the water flow.

[0033] Further, in one embodiment, the water inlet body 111 includes a rotating shell 113 and a water inlet pipe 114 and a water outlet pipe 115 respectively connected to the rotating shell 113. The impeller is rotatably arranged in the rotating shell 113. The water inlet pipe 114 is connected to the water supply pipe or the water tank 200 through a water inlet control valve (not shown) to achieve water inlet. It can be understood that the water inlet control valve can be an electric control valve such as a solenoid valve, or a mechanical valve of a purely mechanical mechanism, as long as the water inlet control of the water inlet pipe 114 can be achieved, and this embodiment does not impose specific restrictions. The water outlet pipe 115 can be connected to a drain pipe or a water tank 200 to achieve drainage.

[0034] Furthermore, the diameter of the water inlet pipe 114 is smaller than the diameter of the water outlet pipe 115. The smaller diameter of the water inlet pipe 114 can speed up the water flow and increase the rotation speed of the impeller, thereby further speeding up the drainage speed and improving the flushing effect on the toilet.

[0035] Furthermore, the water inlet pipe 114 and the water outlet pipe 115 are coaxially arranged to form a water flow channel between the water inlet pipe 114 and the water outlet pipe 115, and the impeller blades are at least partially in contact with the water flow channel to rotate under the impact of the water flow. Specifically, the edges of the impeller blades are in contact with the water flow channel.

[0036] Furthermore, a sealing cover 116 is provided above the rotating housing 113. A sealing ring is provided between the sealing cover 116 and the rotating housing 113. The top of the rotating housing 113 is sealed by the sealing cover 116 and the sealing ring.

[0037] Further, in a specific embodiment, the transmission unit 120 includes a transmission rod 123, and the transmission rod 123 is respectively in transmission cooperation with the rotating member 112 and the pressure plate 130, and the rotating member 112 drives the pressure plate to rotate through the transmission rod 123. Specifically, the transmission unit 120 also includes a driving gear 121 and a transmission gear 122. The driving gear 121 is in circumferential position-limiting cooperation with the rotating member 112. Specifically, the axle of the impeller extends downward to pass through the rotating housing 113, and the driving gear 121 is fixed to the axle of the impeller, and the two are coaxially arranged. The driving gear 121 is in circumferential position-limiting cooperation with the transmission gear 122, specifically, the circumferential side of the driving gear 121 is meshed with the circumferential side of the transmission gear 122. One end of the transmission rod 123 is in circumferential position-limiting cooperation with the transmission gear 122, and the other end is in circumferential position-limiting cooperation with the pressure plate 130. Specifically, the circumferential sides of both ends of the transmission rod 123 are provided with limiting grooves, and the transmission gear 122 and the pressure plate 130 are respectively provided with limiting blocks that cooperate with the limiting grooves at both ends of the transmission rod 123. The transmission gear 122 and the pressure plate 130 can be inserted into the transmission rod 123 in the axial direction, and cooperate with the circumferential limit of the transmission rod 123 to achieve the synchronous rotation of the transmission gear 122, the transmission rod 123 and the pressure plate 130. Further, in order to prevent the pressure plate 130 from coming out in the axial direction, the pressure plate 130 and the transmission rod 123 can be locked and fixed by fasteners such as screws.

[0038] Furthermore, the diameter of the driving gear 121 is larger than that of the transmission gear 122. The larger diameter of the driving gear 121 and the smaller diameter of the transmission gear 122 can increase the rotation speed of the transmission gear 122, thereby increasing the rotation speed of the pressure plate 130 and further improving the flushing effect on the toilet.

[0039] Furthermore, the pressure plate 130 includes a rotating shaft 131 and a plurality of spiral blades 132 arranged around the rotating shaft 131. The blades 132 are arranged in a spiral and inclined manner, which has a stronger pressurizing effect on the drainage channel and better improves the flushing effect of the toilet.

[0040] Further, in one embodiment, the drain valve 140 includes a valve body 141 and a base 142 connected to the valve body 141. The valve body 141 includes a housing 143 and a water stopper 144 movably disposed in the housing 143. The base 142 is disposed below the valve body 141, and the base 142 is provided with an opening 103 for water from the water supply tank 200 to enter and a drain port 148 communicated with the drain channel 201. The drain valve 140 also includes a starter 145, which can control the water stopper 144 to move to open or close the drain port 148. The pressure sheet 130 is disposed in the drain channel 201 or in the base 142.

[0041] In other embodiments, the starter 145 may be a water tank control panel, and the control panel may be an inductive control panel or a mechanical control panel, etc., which may be selected according to specific needs.

[0042] It should be noted that the specific structure of the starter 145 can refer to the drain valve structure in the existing toilet tank, which will not be described in detail here.

[0043] Furthermore, a hollow tube 146 is further provided in the valve body 141, and the transmission rod 123 is passed through the hollow tube 146 and passes through the bottom of the hollow tube 146 to be connected to the pressure plate 130. The pressure plate 130 is arranged below the drain port 148. Specifically, in one embodiment, the hollow tube 146 is movably arranged in the valve body 141, and the water stop member 144 is configured as a water stop pad 147 fixed to the bottom of the hollow tube 146. The water stop pad 147 is adapted to the drain port 148 to open or close the drain port 148. The hollow tube 146 of this embodiment is used as an overflow pipe of the water tank. Of course, an overflow pipe can also be provided separately. The hollow tube 146 is only used for the transmission rod 123 to pass through.

[0044] It is understandable that, in another embodiment, the hollow tube 146 may be fixedly connected to the base 142 , and the water stop member 144 may be configured as a water stop pad 147 movably disposed at the bottom of the valve body 141 , and the water stop pad 147 may be adapted to the drain port 148 to open or close the drain port 148 .

[0045] Furthermore, the base 142 is provided with a fixing rib 149 at the position of the drain port 148 , and is fixed to the transmission rod 123 via the fixing rib 149 , so as to further improve the structural stability of the transmission unit 120 .

[0046] Further, the water inlet body 111 is arranged above the drain valve 140, and the water inlet body 111 is detachably connected to the drain valve 140. Specifically, a positioning sleeve 118 is connected to the lower part of the water inlet body 111 through a connecting piece 117, and the positioning sleeve 118 is detachably connected to the outer shell 143 of the drain valve 140. The positioning sleeve 118 has a sleeve cavity 101 adapted to the top of the outer shell 143, and a positioning sheet 102 is provided on the top of the sleeve cavity 101, and the positioning sheet 102 is fixed to the outer shell 143 by fasteners such as screws.

[0047] Furthermore, the water inlet control valve of the water inlet body 111 cooperates with the starter 145 of the drain valve 140 to control the water inlet control valve to open water inlet when or before the drain port 148 is opened. And after the drain port 148 is closed, the water inlet control valve closes water inlet.

[0048] It should be noted that the linkage between the water inlet control valve of the water inlet body 111 and the starter 145 of the drain valve 140 can be achieved, for example, by a control unit such as a single-chip microcomputer, or by a mechanical linkage mechanism, which is not specifically limited in this embodiment.

[0049] The working process of the drainage speed increasing mechanism 100 is as follows:

[0050] When the drain valve 140 is started, the water inlet body 111 is started at the same time or in advance. The water inlet body 111 is filled with water. Under the impact of the water flow, the impeller rotates, driving the driving gear 121, the transmission gear 122, and the transmission rod 123 to rotate, and then driving the pressure plate 130 to rotate. The pressure plate 130 rotates, pressurizing the drainage channel, increasing the drainage speed, and improving the flushing intensity of the toilet. After the drainage is completed, the water inlet control valve closes the water inlet.

The specific structure of the drainage speed increasing mechanism 100 is described in Example 1.
