Description

Technical Field

[0001] The present invention relates to the technical field of intelligent toilets, and in particular to a spray rod. Background Art

[0002] Flushing is a fundamental function of smart toilets. Current flushing technologies used in these systems are subject to power limitations within the overall electronic control platform. Water temperatures must meet specified standards, and flow rates generally do not exceed 650ml. Under these constraints, to improve flushing effectiveness, most existing methods employ the addition of an air pump for mixing. However, this method produces a messy water spray, making the flushing experience less comfortable.

[0003] In addition, patents CN102146697B and CN103967098 both propose using a pulse pump to improve flushing effectiveness. This method converts a continuous water flow into intermittent droplets at a point on the cleaning surface, generating longitudinal pulses. This method can improve flushing effectiveness to a certain extent, but is less effective for cleaning dirt in narrow grooves.

[0004] Therefore, how to enrich the flushing water splashes of existing smart toilets and improve the flushing effect is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The present invention provides a novel spray boom, which overcomes the deficiencies of the prior art described in the background art.

[0008] a nozzle assembly, which is provided separately from the body, and has a nozzle connected to the water channel of the body;

[0009] The vibration motor is arranged in the nozzle assembly so that when the vibration motor is working, the nozzle assembly is driven to vibrate, and the cleaning water sprayed from the nozzle swings at least in the lateral direction.

[0010] Preferably, the cross-sectional area of ​​the water outlet of the nozzle is 0.5-1.8 mm2.

[0011] Preferably, the vibration frequency of the vibration motor is 80-300 Hz / s.

[0012] Preferably, the front end of the body has a cavity that passes through from top to bottom, and the nozzle assembly is arranged in the cavity and vibrates in the cavity under the drive of the vibration motor.

[0013] Preferably, the nozzle assembly is connected to the body via a flexible connector, and the flexible connector is made of elastic material to reduce the vibration transmitted to the body when the vibration motor is working.

[0014] Preferably, the flexible connector is a hose connecting the main body water channel and the nozzle.

[0015] Preferably, the flexible connection member is a buffer sleeve wrapped around the outer ring of the nozzle assembly, and the buffer sleeve is hung on the main body.

[0016] Preferably, the body has a connecting bracket fixed to the body, the body water channel is connected to the nozzle through the connecting bracket, and the flexible connector connects the connecting bracket and the nozzle assembly.

[0017] Preferably, a water flow path is formed in the flexible connector, and the water flow path is connected to the nozzle.

[0018] Preferably, the nozzle assembly has a receiving cavity for accommodating the vibration motor, and the receiving cavity and the flexible connector are integrally formed.

[0019] The present invention further provides an intelligent toilet, which includes the above-mentioned spray rod.

[0020] Compared with the background technology, the technical solution of the present invention has the following advantages:

[0021] 1. Vibration is used to generate pulsating water in the horizontal direction, providing a new type of flushing water spray and improving the flushing effect;

[0022] 2. Combined with horizontal pulse water, the water outlet hole is appropriately reduced, the water outlet speed will increase, thereby improving the cleaning effect of stubborn dirt;

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-2 As shown, the present invention provides a spray bar comprising a main body 10, a nozzle assembly 20, a vibration motor 30, and a spray bar bracket 40 for receiving the main body 10 and driving the main body 10 to move forward and backward. The nozzle assembly 20 is separate from the main body 10, forming a main body waterway 11 within the main body 10. The nozzle assembly 20 includes nozzles 23 (including a posterior wash nozzle 23-2 and a feminine wash nozzle 23-1), which are connected to the main body waterway 11. The vibration motor 30 is disposed within the nozzle assembly 20 so that when the vibration motor 30 is in operation, it causes the nozzle assembly 20 to vibrate, causing the wash water sprayed from the nozzles 23 to oscillate at least laterally. In this embodiment, the front end of the main body 10 has a cavity 15 extending vertically therethrough. The nozzle assembly 20 is disposed within this cavity 15 and connected to the main body 10 via a flexible connector 21. Driven by the vibration motor 30, the nozzle assembly 20 vibrates within the cavity 15. The flexible connector 21 is made of an elastic material, thereby reducing the vibration transmitted to the main body 10 during operation by the vibration motor 30. Since the vibration motor 30 is built into the nozzle assembly 20 and is independent of the spray boom body 10 , the vibration transmitted to the spray boom body 10 can be minimized and the noise can be reduced.

[0034] In this embodiment, a water flow path is formed within the flexible connector 21, which connects to the nozzle 23. The main body 10 includes a connecting bracket 12 fixed thereto, through which the main body water path 11 communicates with the water flow path. The spray assembly 20 also includes a housing 22 for accommodating the vibration motor 30. The housing 22 is integrally formed with the flexible connector 21 and is also made of an elastic material.

[0035] The main body water channel 11 can be formed by connecting to an external water channel through a hose 13, or the water channel can be formed directly inside the main body. In this embodiment, the main body 10 has a groove for placing the hose 13, and the connecting bracket 12 is provided with a front interface 12-1 and a rear interface 12-2. The front interface 12-1 is connected to the water flow channel of the nozzle assembly 20, and the rear interface 12-2 is connected to the hose 13. In this way, the nozzle 23 is connected to the main body water channel 11 through the connecting bracket 12. The method for fixing the connecting bracket 12 to the main body 10 can be a common connection method and is not limited here. In addition, the outside of the main body 10 is covered with a shell 14, and the main body 14 is assembled as a whole on the spray rod bracket 40, which can realize functions such as telescoping and flushing.

[0036] Thus, the nozzle assembly 20 is connected to the connecting bracket 12 via the flexible connector 21, which also supports the entire nozzle assembly 20. During flushing, the cleaning water flows through the hose 13 to the connecting bracket 12 and then to the nozzle assembly 20. The vibration motor is turned on, and the vibration is transmitted through the accommodating chamber 22 to the posterior washing nozzle 23-2 or the feminine washing nozzle 23-1, causing it to generate a lateral amplitude, thereby driving the water to oscillate and form a sine wave-like water splash.

[0037] The water outlet hole of the nozzle 23 in this application can be appropriately reduced, and the preferred water outlet hole cross-sectional area range is 0.5-1.8mm 2 , if the water outlet hole is reduced in size, the internal pressure will increase, and the water outlet speed will increase, thereby improving the cleaning effect of stubborn dirt. However, if the water outlet hole is too small, the overall cleaning flow rate will be too small, and the cleaning efficiency will be affected. If it is too large, the water outlet speed will decrease, the flushing force will become smaller, and the overall cleaning flow rate will be too large, which will affect the heating power and EMC test of the smart toilet. The water outlet cross-sectional area referred to in this application can be the water outlet cross-sectional area of ​​a single hole, or it can be the sum of the water outlet cross-sectional areas of multiple holes. There is no limitation on the shape of the water outlet hole, which can be circular or other shapes.

[0038] In the present application, the vibration frequency of the vibration motor 30 is selected. Since, under the condition of a certain amplitude, the higher the frequency, the stronger the stimulation, but the higher the frequency, the greater the energy the vibration motor needs to provide, and the larger the volume of the vibration motor will be. Therefore, the vibration frequency of the vibration motor of the present application is preferably 80-300Hz / s, and the mass of the nozzle assembly is as small as possible to reduce the amplitude that the vibration motor needs to provide.

[0039] Figure 3The water spray shape of the prior art longitudinal pulse water and the transverse pulse water of the present application is shown. The nozzle assembly of the present application swings after vibration, and the water flow becomes a water spray similar to a sine wave. The actual cleaning area is increased when the water spray swings rapidly, thereby solving the problem of low cleaning efficiency. The same point A in the cleaning site is taken, and the water amount and time of the point A form a regular intermittent form, i.e. pulse water, when the flushing is performed.

[0040] Figure 4 The cleaning effect of the prior art longitudinal pulse water and the transverse pulse water of the present application on a small and narrow groove of a cleaning surface is shown. When the longitudinal pulse water reaches the narrow groove, the water spray is discontinuous and large, most of which is blocked by the raised parts around the narrow groove, energy is lost, and the cleaning of the bottom of the narrow groove is affected. The transverse pulse water of the present application becomes small when it reaches the narrow groove, and can reach the bottom of the narrow groove, thereby cleaning more completely.

[0041] As Figures 5-6 For another embodiment of the present application, the flexible connecting member 21 is a buffer sleeve wrapped around the outer circle of the nozzle assembly 20, and the buffer sleeve is hung on the body 10. The buttock washing nozzle 23-2 and the female washing nozzle 23-1 can be assembled together and form a containing cavity 22 for accommodating the vibration motor 30 therebetween. Thus, the entire nozzle assembly 20 is connected with the body through the flexible connecting member 21. Since the flexible connecting member 21 is made of an elastic material, the vibration transmitted to the body when the vibration motor works can be reduced, and the noise can be reduced.

[0042] Similarly, the flexible connecting member can also be a hose connecting the water path of the body and the nozzle, and the entire nozzle assembly is supported through the hose. The flexible connecting member can be replaced by other elastic bodies such as springs and elastic plastic walls, which are used to support the entire nozzle assembly. At the same time, the vibration of the nozzle assembly is not obviously hindered, and the noise caused by the vibration is not transmitted to the body.

[0043] The preferred embodiments of the present application are shown and described above. It should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments. The present application can be used in various other combinations, modifications and environments, and can be modified within the scope of the inventive concept disclosed herein by the above teachings or related technical or knowledge. The modifications and changes made by those skilled in the art without departing from the spirit and scope of the present application should be within the protection scope of the claims of the present application.
